Utilizing multiple access technologies such as 5G, 4G, and Wi-Fi within a coherent framework is currently standardized by 3GPP within 5G ATSSS. Indeed, distributing packets over multiple networks can lead to increased robustness, resiliency and capacity. A key part of such a framework is the multi-access proxy, which transparently distributes packets over multiple paths. As the proxy needs to serve thousands of customers, scalability and performance are crucial for operator deployments. In this paper, we leverage recent advancements in data plane programming, implement a multi-access proxy based on the MP-DCCP tunneling approach in P4 and hardware accelerate it by deploying the pipeline on a smartNIC. This is challenging due to the complex scheduling and congestion control operations involved. We present our pipeline and data structures design for congestion control and packet scheduling state management. Initial measurements in our testbed show that packet latency is in the range of 25 μs demonstrating the feasibility of our approach.
A Case Study of the Basic Learners’ Struggles in Guessing from Context to Retain Words Learned
(2022)
Guessing meaning from context is a challenging strategy for Second Language Learners (SLLs). In using the strategy, research found that poor students or low proficiency learners struggled in their attempts to use it. Mainly, it was reported that it was due to their vocabulary knowledge was limited. In another aspect, retaining vocabulary learnt is also important. Such is essential since learning vocabulary does not mean knowing the definition only. Yet, learners must also be able to use the vocabulary as they engage in language skills such as reading, writing, speaking and listening. The study aims at finding the hindrances faced among poor students’ using contextual clues in retaining vocabulary. The study employed a case study to collect data from two basic students studying at a tertiary level. The study found that their hindrances in guessing meaning contexts were due to their being confused in guessing meaning when reading a sentence. Also, it was found that they were not able to find clues since they lacked vocabulary to guess correctly. The study implied that guessing meaning from context required sizeable vocabulary knowledge. Therefore, more training is necessary to assist basic learners in being successful in guessing from contexts.
In einer ethnologisch-vergleichenden Perspektive zeigt Christoph Antweiler auf, dass auch in nichtindustriellen Gesellschaften Gewaltlosigkeit aktiv hergestellt werden muss, welche Ressourcen und kulturellen Kompetenzen dazu erforderlich sind und welche Rolle dritte Personen oder Instanzen dabei spielen können. Mechanismen gewaltfreier Konfliktregelung beschreibt er anhand des Fallbeispiels der Semai in Malaysia.
The two articles of «Langage» and «Langue», published in 1765 in the 9th volume of the great French Encyclopédie by Diderot and D’Alembert, treat some essential philosophical questions on the human ability of communication with linguistic signs. Nevertheless, as the two authors Jaucourt and Beauzée did not share completely identic points of view, the comparative lecture of both articles reveals a complementary perspective, particularly relating to the origin of language as a divine gift or humans’ creation for communicative needs. A further aspect of divergence concerns the textual composition of the article « Langage » as a structured informative text, and the article « Langue » as a long and freely composed writing including personal remarks by the author. The following article deals with the potential of approaches to the Encyclopédie in modern linguistics, concretely demonstrated in the comparative analysis of these two articles.
In 2013, three hundred years had passed since the foundation of the Real Academia Española (RAE). The celebrations accompanying this anniversary were extended across the year and came to a closure with the publication of the 23rd edition of the Diccionario de la lengua española in 2014. Spanish media followed the above-mentioned festivities with a detailed coverage. The purpose of this article is to study the image of the RAE conveyed through the media and the Internet, which can be subsumed under the three terms ‘diverse, democratic and modern’. This form of representation is put into a broader context by considering the linguistic politics pursued by the RAE and the Asociación de Academias de la Lengua Española (ASALE) under the keyword of panhispanism. Finally, a closer look is taken at El buen uso del español, a student manual published by the RAE and the ASALE in 2013, in relation to panhispanism and prescriptivism.
Für die Steinartefakte der ältesten Linearbandkeramik (LBK) liegen bisher kaum mikrofossile oder chemische Analysen zur Herkunftsbestimmung der Rohmaterialien vor, was das Bild der Rohmaterialversorgung auf einem sehr allgemeinen Niveau hält. Es werden die Rohmaterialanalysen des Inventars Langenbach-Niederhummel, Lkr. Freising, Obb., vorgestellt und mit dem bisherigen Forschungsstand diskutiert. Es zeigt sich die intensive Anbindung an das Revier des Ortenburger Raumes, was die Bedeutung der Isar als Verbindungsweg unterstreicht. Aufgrund der technologischen Analyse des Inventars ist von einer Produktion innerhalb der Siedlung auszugehen, was auf eine Selbstversorgung der Siedlung schließen lässt. Dies betont, dass sich die Siedlung in einer eher isolierten Position befand und es noch kein etabliertes Weitergabenetzwerk für Austauschprozesse gab. Mehrere Rohmaterialtypen weisen über das Verbreitungsgebiet der ältesten Linearbandkeramik hinaus. Vor allem die angezeigten transalpinen Verbindungen lassen sich durch weitere Beispiele in einen räumlichen und zeitlichen Kontext setzen. Die Ergebnisse bestätigen eine Kontinuität dieser Routen seit dem Mesolithikum, die sich nach der Linearbandkeramik auch in späteren neolithischen Phasen abzeichnen. Vor dem Hintergrund dieser Ergebnisse stellt sich die Frage nach dem Mobilitätsfaktor, der ursächlich für solche Rohmaterialbezüge ist.

Propofol und Methohexital hemmen die Dünndarmperistaltik. Untersuchungen des Wirkmechanismus am Meerschweinchendünndarm in vitro Fragestellung: Die Hemmung der Darmmotilität durch Anästhetika und Pharmaka zur Analgosedierung von Patienten in der Intensivmedizin kann Ursache weiterer Komplikationen sein. Diese Arbeit untersucht, ob die Hypnotica Propofol und Methohexital einen Einfluss auf die intestinale Peristaltik haben. Methodik: Dünndarmsegmente des Meerschweinchens wurden in vitro in einer Vorrichtung perfundiert, die propulsive Peristaltik ermöglicht. Durch Registrierung des intraluminalen Drucks kann die Schwelle (peristaltic pressure threshold, PPT), ab der peristaltische Kontraktionen ausgelöst werden, bestimmt werden. Propofol, Methohexital, sowie mögliche Antagonisten, wurden den Dünndarmsegmenten extraserosal zupipettiert und die Änderungen der PPT registriert. Ergebnisse: Propofol und Methohexital beeinflussten die Dünndarmperistaltik auf unterschiedliche Art und Weise. Methohexital führte konzentrationsabhängig zu einem Anstieg der PPT, z.T. bis zur kompletten Hemmung der Peristaltik. Im Gegensatz dazu führte die Gabe von Propofol in keinem Fall zur kompletten Hemmung, es zeigte sich lediglich ein Anstieg der PPT. Die Hemmung durch Methohexital trat nach Naloxon und z.T. nach Bicucullin vermindert auf. Die Hemmung der Peristaltik durch Propofol war zumeist unbeeinflusst durch die verwendeten Antagonisten. Schlussfolgerung: Propofol und Methoxital hemmen konzentrationsabhängig die Dünndarmperistaltik des Meerschweinchens. Der hemmende Effekt von Methohexital scheint durch endogene Einflüsse und durch Bindung an vermittelt GABAA- Rezeptoren vermittelt zu werden. Die vorliegenden Daten weisen darauf hin, dass Hypnotika wie Propofol und Methohexital auch auf die menschliche Peristaltik einen hemmenden Einfluss haben und bei Intensivpatienten einen Ileus induzieren oder verschlimmern können. GABA- Rezeptoren scheinen hierbei eine untergeordnete Rolle zu spielen.

This article seeks to analyse urban representation in José Cardoso Pires’s Lisboa – Livro de Bordo (1997), a book dedicated to the author’s home city Lisbon, by focusing on its prevailing nautical and maritime imagery. This imagery as well as its tendency to design Lisbon as a city-ship shall be examined with regard to spatial construction in the Livro de Bordo. Urban sailing as well as the recurrent representations of the Portuguese capital’s spaces as heterotopias will be interpreted as approaches to subvert institutional and homogenic discourses on Lisbon.
This paper discusses complementation strategies in Spanish, focusing on a specific construction most speakers are not aware of: the complementation clause preceded by the verb conocer. Not being a typical complement-taking verb, conocer surprises with a stable and persistent presence throughout the centuries, from Old Spanish to Modern Spanish. After giving an introduction into the field of complementation clauses and one of its main focus of study, grammatical mood, this study uses empirical data from the corpus programs CORDE, CREA and CORPES XXI to show the usage and prevalence of the construction in question. In doing so, this analysis gives a quantitative insight, exemplifying the results with several examples from all ages.
Auf der Grundlage einer quantitativen Analyse untersucht Hans-Jürgen Brandt Konfliktlösungen und deren Wandel unter der Bedingung des Rechtspluralismus in andinen Gemeinschaften Perus und Ecuadors. Die indigene Justiz ist einerseits wegen ihrer friedensstiftenden und integrativen Funktion angesehen, sie ist andererseits aber nicht universalistisch orientiert und steht, beispielsweise im Hinblick auf Körperstrafen, zuweilen in Widerspruch zu den Menschenrechten.

Utilizing multiple access networks such as 5G, 4G, and Wi-Fi simultaneously can lead to increased robustness, resiliency, and capacity for mobile users. However, transparently implementing packet distribution over multiple paths within the core of the network faces multiple challenges including scalability to a large number of customers, low latency, and high-capacity packet processing requirements. In this paper, we offload congestion-aware multipath packet scheduling to a smartNIC. However, such hardware acceleration faces multiple challenges due to programming language and platform limitations. We implement different multipath schedulers in P4 with different complexity in order to cope with dynamically changing path capacities. Using testbed measurements, we show that our CMon scheduler, which monitors path congestion in the data plane and dynamically adjusts scheduling weights for the different paths based on path state information, can process more than 3.5 Mpps packets 25 μs latency.
This article concentrates on the Argentine author Esteban Echeverría who is known as the founding father of Romanticism in the River Plate region. The author of this article intends to show that the importance of Echeverría for the development of Argentine national literature goes beyond the spreading of Romanticist aesthetics. Especially his poem La cautiva (1837) has been regarded as the national epic poem of Argentina because it represents national landscape and the early days of national history. However, as the classification of this narrative poem as the national epic poem already indicates, Echeverría also contributed to the presence of this prestigious genre at the River Plate region. By investigating Echeverría‘s less known verse texts – namely the texts which were read by all Romantics but which have been neglected by literary studies so far – this article illustrates that Echeverría gave decisive impulses for the presence of the epic poem at the River Plate.

The novel Madame Chrysanthème (1887) and the essays collected in Japoneries d’automne (1889) written by French travel author Pierre Loti offer a paradoxical view of Japan during the Meiji period. In both travel writings, the author is torn between aesthetic japonism – which spread all over Europe at the end of the 19th century – and exotic expectations, i.e. the picturesque fascination of the Other. The latter, however, remains unsatisfied throughout his stay. In both writings, Pierre Loti provides an insight into Japan that entirely reflects the spirit of his time. Thereby, he contributes to an image of Japan, which will long remain vivid in the Occident. Contemporaries perceive Loti’s representation of Japan as a realistic testimony, tinged with both sensory impressions and his highly ambiguous feelings towards the distant country, which in the end remained incomprehensible to him.
Auf der Suche nach Frieden. Zur Gestaltung von Nachkriegsordnungen – eine archäologische Spurensuche
(2024)
Ein in der archäologischen Konfliktforschung bislang wenig beachtetes Thema, die Geschehnisse nach Kampfhandlungen und die Etablierung einer Nachkriegsordnung, verbunden mit der Entstehung symbolischer Landschaften als Element einer Erinnerungskultur, behandelt Stefan Burmeister, der unter anderem die Ereignisse nach dem sog. Karfreitagsgefecht der Bundeswehr am 2. April 2010 in Afghanistan und die Rolle der materiellen Kultur in diesem Kontext analysiert.

This article will examine the cinematic approach to the trauma of the Falklands/Malvinas War in Lola Ariasʼ film Teatro de Guerra (AR/ES, 2018). The armed conflict between Ar-gentina and Great Britain in 1982 can be understood as a traumatic liminal experience, whose artistic reception pushes conventional aesthetics to their limits and calls for innova-tive representational strategies. Based on a cultural studies approach to the Falklands/Mal-vinas War as a collective trauma, this contribution will highlight selected moments of aes-thetic border crossing in Teatro de Guerra, by which the film succeeds in transcending boundaries between former enemies of the war.
The nameless protagonist of the postmodern novel Monsieur, written by Belgian author Jean-Philippe Toussaint, can be described as a rather strange man. He lacks ambition, a drive for action and seems to be unfit for daily life. He constantly fails to accomplish his predestined role as a real man, as for instance to pay the bill for dinner when dating a woman. The scope of the present paper is to analyse, on the one hand, how this novel deconstructs hegemonial concepts of masculinity but, on the other hand, is in itself also a parody of the latter.
captar – cap(i)tar, facto – fato: Variation und Wandel bei Plosivsequenzen im Portugiesischen
(2015)
The present study is concerned with the production and perception of the stop consonant clusters /pt/ and /kt/ as well as CVC-Sequences /pVt/ and /kVt/ in European and Brazilian Portuguese (EP and BP, respectively). European and Brazilian Portuguese have the same syllable structure (Bisol 1999: 731, Mateus/d’Andrade 2000: 39), but are postlexically affected by contrary phenomena. After the occurence of phonological processes such as vowel reduction and deletion in European clusters and vowel epenthesis in Brazilian consonant clusters, the difference between lexical consonant clusters and CVC-sequences would be diminished in both varieties, so that EP would realize both as CC, while BP would realize both as CVC. In order to test whether clusters and CVC-sequences can be distinguished in production and perception, we discuss a physiological experiment and a perceptual study with participants of both varieties. The results show less overlap in BP than in EP. The reason for which is seen in the perception of intervocalic epenthetic elements even in lexical clusters in BP and more consonant clusters in EP.

Immersive virtual environments provide users with the opportunity to escape from the real world, but scripted dialogues can disrupt the presence within the world the user is trying to escape within. Both Non-Playable Character (NPC) to Player and NPC to NPC dialogue can be non-natural and the reliance on responding with pre-defined dialogue does not always meet the players emotional expectations or provide responses appropriate to the given context or world states. This paper investigates the application of Artificial Intelligence (AI) and Natural Language Processing to generate dynamic human-like responses within a themed virtual world. Each thematic has been analysed against humangenerated responses for the same seed and demonstrates invariance of rating across a range of model sizes, but shows an effect of theme and the size of the corpus used for fine-tuning the context for the game world.
This paper deals with the origin of the hundred-year old theory of tierras bajas and tierras altas, focusing on the description of vowel weakening within that theory developed in 1921 by Henríquez Ureña. I argue that the early conception of vowel weakening and its dialectal distribution has strongly influenced the kind of research we have been conducting about this phonetic feature to this day. The aim of this study therefore, is to sharpen our understanding of the former zeitgeist of research and to stimulate further big data-based studies on vowel weakening overcoming the traditional dialectal division of tierras bajas and tierras altas.

Nach ersten, wenig erfolgreichen Entwicklungsimpulsen in den 1990er Jahren ist der Online-Lebensmitteleinzelhandel in Deutschland inzwischen in eine Expansionsphase übergegangen, die durch einen Wandel unterschiedlicher Einflussfaktoren begünstigt wurde, so zuletzt beispielsweise durch Rahmenbedingungen der Covid-19-Pandemie. Diese Entwicklung führt dabei nicht nur zu einer Herausbildung neuer oder transformierter Betriebsformen, sondern treibt auch einen Wandel von räumlichen Organisationstrukturen an, der veränderte Standortanforderungen handelnder Akteure mit sich bringt.
Diese Arbeit untersucht jene Veränderungen in Bezug auf Logistik, Lagerinfrastruktur und Filialsysteme anhand von ausgewählten Unternehmensbeispielen aus dem ergänzenden, reinen sowie kombinierten E-Commerce. Dabei bedient sich die Arbeit einerseits am theoretischen Ansatz der Multi-Level-Perspektive aus dem Blickwinkel der Transitionsforschung, um zu ergründen, warum eine Expansion des Online-Lebensmitteleinzelhandels heute im Gegensatz zu den 1990er Jahren begünstigt wird. Andererseits wird mithilfe eines Methodenmixes aus Sekundärdatenanalyse und qualitativer Forschung analysiert, welche Charakteristika die neuen Betriebsformen aufweisen und welche veränderten Ansprüche diese an die Organisationsstruktur sowie die Standorte von Handelsunternehmen stellen.
Dabei kann verdeutlicht werden, dass logistische Abläufe (wie auch der Ort der Warenübergabe) heute eine hohe Relevanz für die Charakteristik einer Betriebsform aufweisen und der Online-Lebensmitteleinzelhandel somit zu einer größeren Hybridisierung des Lebensmitteleinkaufs – überwiegend in urbanen Räumen – führt. Dies zeigt zudem, dass bisherige Betriebsformensystematiken nicht mehr ausreichen, um die komplexen Merkmale der neuen Betriebsformen und Vertriebsmodelle hinreichend abzubilden.
This paper gives an overview of our recent activities in the field of satellite communication networks, including an introduction to geostationary satellite systems and Low Earth Orbit megaconstellations. To mitigate the high latencies of geostationary satellite networks, TCP-splitting Performance Enhancing Proxies are deployed. However, these cannot be applied in the case of encrypted transport headers as it is the case for VPNs or QUIC. We summarize performance evaluation results from multiple measurement campaigns. In a recently concluded project, multipath communication was used to combine the advantages of very heterogeneous communication paths: low data rate, low latency (e.g., DSL light) and high data rate, high latency (e.g., geostationary satellite).
Martin Dinges’ Konzept der „Justiznutzung“ meint eine Instrumentalisierung der Justiz beispielsweise mittels einer gleichzeitigen oder alternativen Nutzung verschiedener justizförmiger Angebote nach Opportunitätskriterien. Ausgehend von diesem Konzept, ermittelt er Gemeinsamkeiten mit und Differenzen zu der Nutzung medizinischer Angebote in der europäischen Frühmoderne.
