  abstract  = {This is a pilot study that examined the effect of cell-phone conversation on cognition using a continuous multitasking paradigm. Current theorizing argues that phone conversation affects behavior (e.g., driving) by interfering at a level of cognitive processes (not peripheral activity) and by implying an attentional-failure account. Within the framework of an intermittent spare-utilized capacity threading model, we examined the effect of aspects of (secondary-task) phone conversation on (primary-task) continuous arithmetic performance, asking whether phone use makes components of automatic and controlled information-processing (i.e., easy vs. hard mental arithmetic) run more slowly, or alternatively, makes processing run less reliably albeit with the same processing speed. The results can be summarized as follows: While neither expecting a text message nor expecting an impending phone call had any detrimental effects on performance, active phone conversation was clearly detrimental to primary-task performance. Crucially, the decrement imposed by secondary-task (conversation) was not due to a constant slowdown but is better be characterized by an occasional breakdown of information processing, which differentially affected automatic and controlled components of primary-task processing. In conclusion, these findings support the notion that phone conversation makes individuals not constantly slower but more vulnerable to commit attention failure, and in this way, hampers stability of (primary-task) information processing.},

  abstract  = {Gegenstand der vorliegenden Arbeit war eine systematische Analyse der Ver-arbeitbarkeit, Abbindedauer, pH Wert- und Temperatur-Verl{\"a}ufe w{\"a}hrend des Abbindens und der Eigenschaften der ausgeh{\"a}rteten Zementpaste, welche je-weils aus Farringtonit (Mg3(PO4)2) unterschiedlicher Reaktivit{\"a}t bestand und mit Diammoniumhydrogenphosphat und Polyacryls{\"a}ure zur Reaktion gebracht und konventionellen w{\"a}ssrigen Zementsystemen gegen{\"u}bergestellt wurde. Ein besonderer Fokus wurde hierbei auf die Beurteilbarkeit der Eignung dieser Zementsysteme als injizierbare Zementpasten in m{\"o}glicherweise lasttragenden Bereichen gelegt. Eine Reaktivierung von Farringtonit und anschließendes Ab-binden mit Wasser konnte durch Hochenergiemahlung f{\"u}r 2 h bis 24 h erzielt werden. Mechanisch aktiviertes Farringtonit mit Polyacryls{\"a}ure (100.000 g/mol) bzw. kurzzeitig gemahlenes Farringtonit mit h{\"o}her molekulargewichtiger Polyac-ryls{\"a}ure f{\"u}hrte auf Grund der zum Teil summierten Reaktivit{\"a}t in der sauren Umgebung der Polyacryls{\"a}ure zu einer schlechten Verarbeitbarkeit und unzu-reichenden Druckfestigkeiten. Um chelatisiertes Farringtonit mit angemessenen Festigkeiten zu erhalten, zeigte sich die Anwesenheit von Ammoniumionen als vielversprechende Strategie. Als hydratisierte Produkte wurden je nach Formu-lierung Struvit (MgNH4PO4·6H2O), Newberyit (MgHPO4·3H2O) oder Mag-nesiumphosphathydrat (Mg3(PO4)2·22H2O) gewonnen. Besonders die Kombina-tion von kurzzeitig gemahlenem Farringtonit mit 17,5 Gew.\%iger Poly-acryls{\"a}ure L{\"o}sung und 23,1 Gew.\%iger Diammoniumhydrogenphos-phat L{\"o}sung mit einem Pulver-zu-Fl{\"u}ssigkeitsverh{\"a}ltnis von 1,5 g/ml f{\"u}hrte zu Zementpasten, die hinsichtlich ihres Abbindeverhaltens und der mechanischen Eigenschaften denen der Einzelbestandteile {\"u}berlegen waren. Die entwickelten Zementsysteme zeigten 60 min nach Beginn des Abbindevor-gangs einen pH-Wert von 4,7 bis 6,4 und Temperaturmaxima von 28,5 °C bis 52 °C je nach Zusammensetzung. Der Mischzement, f{\"u}r welchen maximale Druckfestigkeiten von 15,0±4,1 MPa gemessen wurden, zeigte ein deutlich we-niger spr{\"o}des Bruchverhalten im Vergleich zu den reinen Verd{\"u}nnungen. Da der spr{\"o}de Charakter klassischer mineralische Knochenzemente einen limitie-renden Faktor f{\"u}r die Anwendung in lasttragenden Bereichen darstellt, kann dies als deutliche Verbesserung der mechanischen Eigenschaften beurteilt wer-den. Immerhin lagen die erzielten Festigkeitswerte in der Gr{\"o}ßenordnung der humanen Spongiosa. Besonders hervorzuheben ist außerdem der synergisti-sche Effekt, welcher bei Zementformulierungen aus kurzzeitig gemahlenem Farringtonit mit 17,5 Gew.\%iger Polyacryls{\"a}ure L{\"o}sung und 23,1 Gew.\%iger Diammoniumhydrogenphosphat L{\"o}sung mit einem Pulver-zu-Fl{\"u}ssigkeitsver-h{\"a}ltnis von 1,5 g/ml beobachtet werden konnte. Diese Formulierung wies bis zu vierfach h{\"o}here Festigkeitswerte als die Einzelbestandteile auf. Somit bildet das entwickelte Mischzement-System eine gute Basis f{\"u}r weitere Entwicklungen hin zu mechanisch lasttragenden Defekten.},

  abstract  = {This dissertation investigates selected causes and effects of worker mobility between firms in three empirical studies for Germany. Chapter 2 investigates the productivity effects of worker inflows to manufacturing establishments, distinguishing inflows by their previous employers' wage level, as a proxy for productivity. The chapter is motivated by several empirical studies which find that worker inflows from more productive or higher-paying firms increase hiring firms' productivity. The analyses in chapter 2 are based on a unique linked employer-employee data set. The findings indicate that inflows from higher-paying establishments do not increase hiring establishments' productivity, but inflows from lower-paying establishments do. Further analyses suggest that this effect is due to a positive selectivity of such inflows from their sending establishments. These findings can be interpreted as evidence of a reallocation process by which the best employees of lower-paying establishments become hired by higher-paying establishments. This process reflects the assortative pattern of worker mobility in Germany documented by Card et al. (2013) for the past decades. The chapter thus contributes to the literature by linking establishment-level productivity analysis to the assortative pattern of inter-firm worker mobility, thereby providing a micro-foundation for the latter. Chapter 3 focuses on a positive selection of workers moving between firms from another, more specific perspective. The analysis focuses on the importance of regional labor market competition for establishments' apprentice training and poaching of apprenticeship completers. Previous studies have found that firms provide less training if they are located in regions with strong labor market competition. This finding is usually interpreted as evidence of a higher risk of poaching in these regions. Yet, there is no direct evidence that regional competition is positively correlated with poaching. Building on a recently established approach to ex-post identify poaching of apprenticeship completers, this chapter is the first to directly investigate the correlation between regional labor market competition and poaching. Using German administrative data, it is found that competition indeed increases training establishments' probability of becoming poaching victims. However, poaching victims do not change their apprenticeship training activity in reaction to poaching. Instead, the findings indicate that the lower training activity in competitive regions can be attributed to lower retention rates, as well as a less adverse selection and lower labor and hiring costs of apprenticeship completers hired from rivals. Chapter 4 investigates the effects of local broadband internet availability on establishment-level employment growth. The analysis uses data for Germany in the years 2005-2009, when broadband was introduced in rural regions of Western Germany and in large parts of Eastern Germany. Technical frictions in broadband rollout are exploited to obtain exogenous variation in local broadband availability. The results suggest that broadband expansion had a positive effect on employment growth in the Western German service sector and a negative effect in Western German manufacturing, suggesting that broadband expansion has accelerated the reallocation of workers from manufacturing to services. Furthermore, this pattern of results is driven by pronounced positive effects in knowledge- and computer-intensive industries, suggesting that it is the actual use of broadband in the production process that leads to complementary hiring, respectively a slowdown of employment growth, in the respective sectors. For Eastern Germany, no significant employment growth effects are found.},

  abstract  = {Background: There is a paucity of studies examining the safety of venom immunotherapy (VIT) in children. We aimed to assess the incidence of anaphylactic side effects during rush VIT in a cohort of pediatric patients and adult controls. Methods: 72 consecutive cycles of VIT-buildup in 71 children/adolescents aged 7-17 years were retrospectively evaluated and compared to an adult control group (n = 981) with regard to baseline parameters (sex, causative venom, severity of index sting reaction, results of allergy testing, comorbidities) and the incidence of anaphylactic adverse reactions. Results: Compared to adults, severe index sting-induced anaphylaxis was significantly less common in children (P = .001). Children were more likely to suffer from bee venom allergy (P < .001) and showed higher levels of bee venom-specific IgE (P = .013), but lower serum tryptase concentrations (P = .014). The overall rate of VIT-induced anaphylactic reactions was higher in children than in adults (6.9\% vs 2.5\%, P = .046 by univariate analysis). In the final binary logistic regression model, however, only bee VIT (P = .039; odds ratio 2.25; confidence interval 1.04-4.87) and 5-day compared to 3-day buildup protocols (P = .011; odds ratio 2.64; confidence interval 1.25-5.57) were associated with an increased risk of treatment-induced anaphylaxis. All pediatric patients finally reached and tolerated the target maintenance dose of 100 µg. Conclusions: The higher anaphylactic reaction rate observed in pediatric patients may be attributed to a greater prevalence of bee venom allergy. VIT-induced anaphylaxis in children is usually mild and does not affect further updosing and maintenance of VIT.},

Fabricated in a wet-chemical procedure, the spherical NPs with a diameter of 5-10 nm show a crystalline structure.

Owing to the Gd\(^{3+}\) ions on the surface, the NPs reduce the MR T\(_{1}\) relaxation time constant as a function of their concentration. Thus, the NPs can be used as a MRI CA with a mean relaxivity of about r = 0.471 mL·mg\(^{-1}\)·s\(^{-1}\). Repeated MRI examinations of four different batches prove the reproducibility of the NP synthesis and determine the long-term stability of the CAs.

  abstract  = {Platelets are continuously produced from megakaryocytes (MK) in the bone marrow by a cytoskeleton-driven process of which the molecular regulation is not fully understood. As revealed in this thesis, MK/ platelet-specific Profilin1 (Pfn1) deficiency results in micro- thrombocytopenia, a hallmark of the Wiskott-Aldrich syndrome (WAS) in humans, due to accelerated platelet turnover and premature platelet release into the bone marrow. Both Pfn1-deficient mouse platelets and platelets isolated from WAS patients contained abnormally organized and hyper-stable microtubules. These results reveal an unexpected function of Pfn1 as a regulator of microtubule organization and point to a previously unrecognized mechanism underlying the platelet formation defect in WAS patients. In contrast, Twinfilin2a (Twf2a) was established as a central regulator of platelet reactivity and turnover. Twf2a-deficient mice revealed an age-dependent macrothrombocytopenia that could be explained by a markedly decreased platelet half-life, likely due to the pronounced hyper-reactivity of \(Twf2a^{-/-}\) platelets. The latter was characterized by sustained integrin acti- vation and thrombin generation in vitro that translated into accelerated thrombus formation in vivo. To further elucidate mechanisms of integrin activation, Rap1-GTP-interacting adaptor molecule (RIAM)-null mice were generated. Despite the proposed critical role of RIAM for platelet integrin activation, no alterations in this process could be found and it was concluded that RIAM is dispensable for the activation of β1 and β3 integrins, at least in platelets. These findings change the current mechanistic understanding of platelet integrin activation. Outside-in signaling by integrins and other surface receptors was supposed to regulate MK migration, but also the temporal and spatial formation of proplatelet protrusions. In this the- sis, phospholipase D (PLD) was revealed as critical regulator of actin dynamics and podo- some formation in MKs. Hence, the unaltered platelet counts and production in \(Pld1/2^{-/-}\) mice and the absence of a premature platelet release in the bone marrow of \(Itga2^{-/-}\) mice question the role of podosomes in platelet production and raise the need to reconsider the proposed inhibitory signaling by α2β1 integrins on proplatelet formation. Non-muscle myosin IIA (NMMIIA) has been implicated as a downstream effector of the in- hibitory signals transmitted via α2β1 integrins. Besides Rho-GTPase signaling, also \(Mg^{2+}\) and transient receptor potential melastatin-like 7 (TRPM7) channel α-kinase are known regulators of NMMIIA activity. In this thesis, TRPM7 was identified as major regulator of \(Mg^{2+}\) homeostasis in MKs and platelets. Furthermore, decreased \([Mg^{2+}]_i\) led to deregulated NMMIIA activity and altered cytoskeletal dynamics that impaired thrombopoiesis and resulted in macrothrombocytopenia in humans and mice.},

Such devices range from novel coherent light emitters to reconfigurable potential landscapes for electro-optical polariton-lattice based quantum simulators as well as building blocks of optical logic architectures. Especially for the latter, the strongly interacting nature of the light-matter hybrid particles has been used to facilitate fast and efficient switching of light by light, something which is very hard to achieve with weakly interacting photons. We demonstrate here that polariton transistor switches can be fully integrated in electro-optical schemes by implementing a one-dimensional polariton channel which is operated by an electrical gate rather than by a control laser beam. The operation of the device, which is the polariton equivalent to a field-effect transistor, relies on combining electro-optical potential landscape engineering with local exciton ionization to control the scattering dynamics underneath the gate. We furthermore demonstrate that our device has a region of negative differential resistance and features a completely new way to create bistable behavior.},

  abstract  = {MicroRNAs play an important role in the interplay between bacterial pathogens and host cells, participating as host defense mechanisms, as well as exploited by bacteria to subvert host cellular functions. Here, we show that microRNAs modulate infection by Shigella flexneri, a major causative agent of bacillary dysentery in humans. Specifically, we characterize the dual regulatory role of miR-29b-2-5p during infection, showing that this microRNA strongly favors Shigella infection by promoting both bacterial binding to host cells and intracellular replication. Using a combination of transcriptome analysis and targeted high-content RNAi screening, we identify UNC5C as a direct target of miR-29b-2-5p and show its pivotal role in the modulation of Shigella binding to host cells. MiR-29b-2-5p, through repression of UNC5C, strongly enhances filopodia formation thus increasing Shigella capture and promoting bacterial invasion. The increase of filopodia formation mediated by miR-29b-2-5p is dependent on RhoF and Cdc42 Rho-GTPases. Interestingly, the levels of miR-29b-2-5p, but not of other mature microRNAs from the same precursor, are decreased upon Shigella replication at late times post-infection, through degradation of the mature microRNA by the exonuclease PNPT1. While the relatively high basal levels of miR-29b-2-5p at the start of infection ensure efficient Shigella capture by host cell filopodia, dampening of miR-29b-2-5p levels later during infection may constitute a bacterial strategy to favor a balanced intracellular replication to avoid premature cell death and favor dissemination to neighboring cells, or alternatively, part of the host response to counteract Shigella infection. Overall, these findings reveal a previously unappreciated role of microRNAs, and in particular miR-29b-2-5p, in the interaction of Shigella with host cells.},

  abstract  = {Der Stellenwert der Erhaltungstherapie mit Gemcitabin (GEM), die im Anschluss an die Cisplatin-basierte Polychemotherapie (CBPC) bei den radikal operativ vorbehandelten Patienten mit fortgeschrittenem Urothelkarzinom (UC) erfolgt, bleibt bis dato unklar. In der vorliegenden Arbeit konnten die Ergebnisse der GEM-Erhaltungstherapie mittels retrospektiver Analyse evaluiert werden. Zwischen 1999 und 2013 erhielten 38 operativ vorbehandelte Patienten im Anschluss an die prim{\"a}re CBPC zus{\"a}tzlich im viertelj{\"a}hrlichen Intervall zwei konsekutive Infusionen von GEM (1 250 mg/m2) als Erhaltungstherapie. Dieses Kollektiv wurde durch ein ebenso operativ vorbehandeltes Kontrollkollektiv (n = 38), das lediglich eine prim{\"a}re CBPC erhielt, mittels eines `Propensity Score Matching`-Verfahrens gematched. Mittels Kaplan-Meier-Sch{\"a}tzungen mitsamt dem Log-rank-Test wurden die Gesamt{\"u}berlebens- und tumorspezifische {\"U}berlebensraten sowie das progressionsfreie {\"U}berleben in beiden Kollektiven beurteilt. Die Analyse der {\"U}berlebensdaten erfolgte durch die Regressionsmethode nach Cox (proportionales Hazard Modell). Die mediane Follow-Up Zeit betrug 37 Monate bei einem Interquartilsabstand von 9 bis 148 Monaten. Die Patienten, die die GEM-Erhaltungstherapie erhielten, zeigten signifikant bessere Ergebnisse bez{\"u}glich der Gesamt-5-Jahres-{\"U}berlebensrate (49,2 vs. 26,5 \%, p = 0,0314) sowie der tumorspezifischen 5-Jahres-{\"U}berlebensrate (61,3 vs. 33,4 \%, p = 0,0386). Dabei ergab sich in beiden Kollektiven kein statistisch signifikanter Unterschied bez{\"u}glich des progressionsfreien 5-Jahres-{\"U}berlebens (10,3 vs. 16,1 \%, p = 0,134). Es ist dargelegt, dass die zus{\"a}tzliche GEM-Erhaltungschemotherapie nach Abschluss der prim{\"a}ren CBPC bei operativ vorbehandelten Patienten mit fortgeschrittenem UC sowohl Gesamt- als auch tumorspezifisches {\"U}berleben (wenngleich an einem kleinen Patientenkollektiv) verbessern kann. Der Einfluss der GEM-Erhaltungstherapie auf das progressionsfreie {\"U}berleben sollte in prospektiven Studien mit großer Patientenanzahl k{\"u}nftig evaluiert werden.},

  abstract  = {Als W{\"a}rmed{\"a}mmstoffe werden {\"u}blicherweise makropor{\"o}se Stoffsysteme wie Sch{\"a}ume, Pul-versch{\"u}ttungen, Faservliese und - wolle eingesetzt. Zus{\"a}tzlich finden mikro- und mesopor{\"o}se D{\"a}mmstoffe wie Aerogele Anwendung. Um effiziente W{\"a}rmed{\"a}mmstoffe entwickeln zu k{\"o}nnen, muss der Gesamtw{\"a}rmetransport in por{\"o}sen Materialien verstanden werden. Die ein-zelnen W{\"a}rmetransport-Mechanismen Festk{\"o}rperw{\"a}rmeleitung, Gasw{\"a}rmeleitung und W{\"a}rme-strahlung k{\"o}nnen zuverl{\"a}ssig analytisch beschrieben werden. Bei manchen por{\"o}sen Materialien liefert jedoch auch eine Wechselwirkung zwischen den verschiedenen W{\"a}rmetransport-Mechanismen, d.h. die Kopplung von Festk{\"o}rper- und Gasw{\"a}rmeleitung, einen hohen Beitrag zur Gesamtw{\"a}rmeleitf{\"a}higkeit. Wie hoch dieser Kopplungseffekt bei einer bestimmten Probe ausf{\"a}llt, kann bisher schwer abgesch{\"a}tzt werden. Um den Kopplungseffekt von Festk{\"o}rper- und Gasw{\"a}rmeleitung besser zu verstehen, sind sowohl experimentelle als auch theoretische Untersuchungen an verschiedenen por{\"o}sen Stoffsystemen erforderlich. Zus{\"a}tzlich kann ein zuverl{\"a}ssiges theoretisches Modell dazu beitragen, die mittlere Porengr{\"o}ße von por{\"o}sen Mate-rialien zerst{\"o}rungsfrei anhand von gasdruckabh{\"a}ngigen W{\"a}rmeleitf{\"a}higkeitsmessungen zu bestimmen. Als Modellsystem f{\"u}r die experimentellen Untersuchungen wurde der hochpor{\"o}se Feststoff Aerogel verwendet, da seine strukturellen Eigenschaften wie Porengr{\"o}ße und Dichte w{\"a}hrend der Synthese gut eingestellt werden k{\"o}nnen. Es wurden Resorcin-Formaldehyd-Aerogele mit mittleren Porengr{\"o}ßen von etwa 600 nm, 1 µm und 8 µm sowie daraus mittels Pyrolyse abge-leitete Kohlenstoff-Aerogele synthetisiert und jeweils hinsichtlich ihrer Struktur und W{\"a}rme-leitf{\"a}higkeiten experimentell charakterisiert. Die Gesamtw{\"a}rmeleitf{\"a}higkeiten dieser Aerogele wurden f{\"u}r verschiedene Gasatmosph{\"a}ren (Kohlenstoffdioxid, Argon, Stickstoff und Helium) in Abh{\"a}ngigkeit vom Gasdruck durch das Hitzdraht-Verfahren bestimmt. Hierf{\"u}r wurde der Messbereich der Hitzdraht-Apparatur des ZAE Bayern mittels einer Druckzelle auf 10 MPa erweitert. Die Messergebnisse zeigen, dass bei allen Aerogel-Proben Festk{\"o}rper- und Gasw{\"a}r-meleitung einen deutlichen Kopplungsbeitrag liefern: Die gemessenen gasdruckabh{\"a}ngigen W{\"a}rmeleitf{\"a}higkeiten sind um Faktor 1,3 bis 3,3 h{\"o}her als die entsprechenden reinen Gas-w{\"a}rmeleitf{\"a}higkeiten. Die jeweilige H{\"o}he h{\"a}ngt sowohl vom verwendeten Gas (Gasw{\"a}rmeleitf{\"a}higkeit) als auch vom Aerogeltyp (Festk{\"o}rperw{\"a}rmeleitf{\"a}higkeit und Festk{\"o}rperstruktur) ab. Ein stark vernetzter Festk{\"o}rper verursacht beispielsweise einen niedrigeren Kopplungsbei-trag als ein weniger stark vernetzter Festk{\"o}rper. Andererseits wurde die gasdruckabh{\"a}ngige W{\"a}rmeleitf{\"a}higkeit von Melaminharzschaum - einem flexiblen, offenporigen und hochpor{\"o}sen Material - in einer evakuierbaren Zwei-Plattenapparatur unter Stickstoff-Atmosph{\"a}re bestimmt. Das Material zeichnet sich dadurch aus, dass die Addition der Einzelw{\"a}rmeleitf{\"a}higkeiten gut erf{\"u}llt ist, d.h. kein Kopplungsef-fekt auftritt. Allerdings konnte gezeigt werden, dass die gestauchte und damit unregelm{\"a}ßige Struktur von Melaminharzschaum die Kopplung von Festk{\"o}rper- und Gasw{\"a}rmeleitung deut-lich beg{\"u}nstigt. Je st{\"a}rker die Melaminharzschaumprobe komprimiert wird, umso st{\"a}rker f{\"a}llt der Kopplungseffekt aus. Bei einer Kompression um 84 \% ist beispielsweise die gemessene gasdruckabh{\"a}ngige W{\"a}rmeleitf{\"a}higkeit bei 0,1 MPa um ca. 17 \% gegen{\"u}ber der effektiven W{\"a}rmeleitf{\"a}higkeit von freiem Stickstoff erh{\"o}ht. Die experimentellen Untersuchungen wurden durch theoretische Betrachtungen erg{\"a}nzt. Zum einen wurde die Kopplung von Festk{\"o}rper- und Gasw{\"a}rmeleitung anhand einer Serienschal-tung der thermischen Widerst{\"a}nde von Festk{\"o}rper- und Gasphase dargestellt, um die Abh{\"a}n-gigkeit von verschiedenen Parametern zu untersuchen. Dadurch konnte gezeigt werden, dass der Kopplungsterm stets von den Verh{\"a}ltnissen aus Festk{\"o}rper- und Gasw{\"a}rmeleitf{\"a}higkeit sowie aus den geometrischen Parametern beider Phasen abh{\"a}ngt. Des Weiteren wurden mit dem Computerprogramm HEAT2 Finite-Differenzen-Simulationen an Modellstrukturen durchgef{\"u}hrt, die f{\"u}r por{\"o}se Stoffsysteme, insbesondere Aerogel, charakteristisch sind (Stege, H{\"a}lse, Windungen und tote Enden). Die simulierten gasdruckabh{\"a}ngigen W{\"a}rmeleitf{\"a}higkeiten zeigen deutlich, dass die Festk{\"o}rperstruktur mit der geringsten Vernetzung, d.h. das tote Ende, am meisten zur Kopplung von Festk{\"o}rper- und Gasw{\"a}rmeleitung beitr{\"a}gt. Dies korre-liert mit den experimentellen Ergebnissen. Dar{\"u}ber hinaus kann man erkennen, dass die Ge-samtw{\"a}rmeleitf{\"a}higkeit eines schlecht vernetzten por{\"o}sen Systems, wo also ein hoher Kopp-lungseffekt (Serienschaltung) auftritt, niemals gr{\"o}ßer wird als die eines gut vernetzten Sys-tems mit gleicher Porosit{\"a}t, wo haupts{\"a}chlich paralleler W{\"a}rmetransport durch beide Phasen stattfindet. Schließlich wurden drei Modelle entwickelt bzw. modifiziert, um die gasdruckabh{\"a}ngige W{\"a}rmeleitf{\"a}higkeit von por{\"o}sen Stoffsystemen theoretisch beschreiben zu k{\"o}nnen. Zun{\"a}chst wurde ein f{\"u}r Kugelsch{\"u}ttungen entwickeltes Modell f{\"u}r Aerogel angepasst, d.h. Kopplung von Festk{\"o}rper- und Gasw{\"a}rmeleitung wurde nur in den L{\"u}cken zwischen zwei benachbarten Partikeln ber{\"u}cksichtigt. Ein Vergleich mit den Messkurven zeigt, dass der ermittelte Kopplungsterm zu gering ausf{\"a}llt. Daher wurde ein bereits existierendes Aerogelmodell mit kubischer Einheitszelle, welches zus{\"a}tzlich Kopplung zwischen den einzelnen Partikelstr{\"a}ngen beinhaltet, verbessert. Auch dieses Modell liefert keine zufriedenstellende {\"U}bereinstimmung mit den Messwerten, denn der Kopplungsbeitrag wird immer noch untersch{\"a}tzt. Das liegt daran, dass die gew{\"a}hlte regelm{\"a}ßige kubische Struktur f{\"u}r Aerogel zu ungenau ist. So geht bei der Berechnung des Kopplungsterms der bereits erw{\"a}hnte hohe Beitrag durch tote Enden (und auch Windungen) verloren. Erfahrungsgem{\"a}ß k{\"o}nnen jedoch alle f{\"u}r Aerogel erhaltenen gasdruckabh{\"a}ngigen Messkurven mit dem sogenannten Skalierungsmodell relativ gut beschrieben werden. Das entspricht dem Knudsen-Modell f{\"u}r reine Gasw{\"a}rmeleitung, welches mit einem konstanten Faktor skaliert wird. Die Anwendung dieses einfachen Modells auf die Messdaten hat gezeigt, dass die Akkommodationskoeffizienten von Helium in Aerogel deut-lich h{\"o}her sind als die Literaturwerte (ca. 0,3 auf Metalloberfl{\"a}chen): In den vermessenen RF- und Kohlenstoff-Aerogelen lassen sich Akkommodationskoeffizienten nahe 1 f{\"u}r Helium ab-leiten. Dar{\"u}ber hinaus ist das Skalierungsmodell gut geeignet, die mittleren Porengr{\"o}ßen por{\"o}ser Materialien zuverl{\"a}ssig aus gasdruckabh{\"a}ngig gemessenen W{\"a}rmeleitf{\"a}higkeitskurven zu bestimmen. Dies stellt somit eine unkomplizierte und zerst{\"o}rungsfreie Charakterisierungsmethode dar.},

It is shown that by tuning the quantum well parameters one can strongly disturb the 0D-character of the coupled system ground state, initially located in a dot. The out-coupling of either an electron or a hole state from the quantum dot confining potential is viewed by a significant elongation of the photoluminescence decay time constant. Band structure calculations show that in the GaAs-based coupled system at its ground state a hole remains isolated in the dot, whereas an electron gets delocalized towards the quantum well. The opposite picture is built for the ground state of a coupled system based on InP.},

  abstract  = {We theoretically investigate the propagation of heat currents in a three-terminal quantum dot engine. Electron-electron interactions introduce state-dependent processes which can be resolved by energy-dependent tunneling rates. We identify the relevant transitions which define the operation of the system as a thermal transistor or a thermal diode. In the former case, thermal-induced charge fluctuations in the gate dot modify the thermal currents in the conductor with suppressed heat injection, resulting in huge amplification factors and the possible gating with arbitrarily low energy cost. In the latter case, enhanced correlations of the state-selective tunneling transitions redistribute heat flows giving high rectification coefficients and the unexpected cooling of one conductor terminal by heating the other one. We propose quantum dot arrays as a possible way to achieve the extreme tunneling asymmetries required for the different operations.},

  abstract  = {Bone fractures typically heal without surgical intervention. However, pathological situations exist which impede the healing process resulting in so-called non-union fractures. Such fractures are nowadays treated with scaffold material being introduced into the defect area. These scaffolds can be doped with osteogenic factors, such as bone morphogenetic protein (BMP)2. BMP2 belongs to the most osteogenic growth factors known to date. Its medical use, efficiency and safety have been approved by FDA for certain applications. Currently, BMP2 is distributed with a stabilizing scaffold, which is simply soaked with the growth factor. Due to fast release kinetics supraphysiological high doses of BMP2 are required which are causally associated with severe side effects observed in certain applications being most harmful in the area of the cervical spine. These side-effects include inflammation, swelling and breathing problems, leading to disastrous consequences or secondary surgical interventions. Since it could be shown that a retardation of BMP2 release from the scaffold resulted in superior bone forming properties in vivo, it seems obvious to further reduce this release to a minimum. This can be achieved by covalent coupling which in the past was already elaborated using mainly classical EDC/NHS chemistry. Using this technique coupling of the protein occurs non-site-directedly leading mainly to an unpredictable product outcome with variable osteogenic activities. In order to improve the reproducibility of scaffold functionalization by BMP2 we created variants one of which contains a unique unnatural amino acid substitution within the mature polypeptide sequence (BMP2-K3Plk) and another, BMP2-A2C, in which an N-terminal alanine has been substituted by cysteine. These modifications enable site-specific and covalent immobilization of BMP2 e.g. onto polymeric beads. Both proteins were expressed in E. coli, renatured and purified by cation-exchange chromatography. Both variants were extensively analyzed in terms of purity and biological activity which was tested by in vitro interaction analyses as well as in cell based assays. Both proteins could be successfully coupled to polymeric beads. The different BMP2 functionalized beads were shown to interact with the ectodomain of the type I receptor BMPR-IA in vitro indicating that the biological activity of both BMP2 variants retained upon coupling. Both functionalized beads induced osteogenic differentiation C2C12 cells but only of those cells which have been in close contact to the particular beads. This strongly indicates that the BMP2 variant are indeed covalently coupled and not just adsorbed. We claim that we have developed a system for a site-specific and covalent immobilization of BMP-2 onto solid scaffolds, potentially eliminating the necessity of high-dose scaffold loading. Since immobilized proteins are protected from removal by extracellular fluids, their activities now rely mainly on the half-life of the used scaffold and the rate of proteolytic degradation. Assuming that due to prolonged times much lower loading capacities might be required we propose that the immobilization strategy employed in this work may be further refined and optimized to replace the currently used BMP2-containing medical products.},

  abstract  = {Many pathogenic bacteria utilize specialized secretion systems to deliver proteins called effectors into eukaryotic cells for manipulation of host pathways. The vast majority of known effector targets are host proteins, whereas a potential targeting of host nucleic acids remains little explored. There is only one family of effectors known to target DNA directly, and effectors binding host RNA are unknown. Here, we take a two-pronged approach to search for RNA-binding effectors, combining biocomputational prediction of RNA-binding domains (RBDs) in a newly assembled comprehensive dataset of bacterial secreted proteins, and experimental screening for RNA binding in mammalian cells. Only a small subset of effectors were predicted to carry an RBD, indicating that if RNA targeting was common, it would likely involve new types of RBDs. Our experimental evaluation of effectors with predicted RBDs further argues for a general paucity of RNA binding activities amongst bacterial effectors. We obtained evidence that PipB2 and Lpg2844, effector proteins of Salmonella and Legionella species, respectively, may harbor novel biochemical activities. Our study presenting the first systematic evaluation of the RNA-targeting potential of bacterial effectors offers a basis for discussion of whether or not host RNA is a prominent target of secreted bacterial proteins.},
