In this paper, we investigate the phase diagram of the interacting Fermi gas with Rashba-type spin-orbit coupling (SOC) on a square optical lattice. The phase diagram is investigated in a wide range of atomic interactions and SOC strength within the framework of the cluster dynamical mean-field theory (CDMFT). We show that the interplay between the atomic interactions and SOC results in a rich phase diagram. In the deep Mott insulator regime, the SOC can induce diverse spin ordered phases. Whereas near the metal-insulator transition (MIT), the SOC tends to destroy the conventional antiferromagnetic fluctuations, giving rise to distinctive features of the MIT. Furthermore, the strong fluctuations arising from SOC may destroy the magnetic orders and trigger an order to disorder transition in close proximity of the MIT.}, language = {en} } @article{SunStarlyDalyetal.2020, author = {Sun, Wei and Starly, Binil and Daly, Andrew C and Burdick, Jason A and Groll, J{\"u}rgen and Skeldon, Gregor and Shu, Wenmiao and Sakai, Yasuyuki and Shinohara, Marie and Nishikawa, Masaki and Jang, Jinah and Cho, Dong-Woo and Nie, Minghao and Takeuchi, Shoji and Ostrovidov, Serge and Khademhosseini, Ali and Kamm, Roger D and Mironov, Vladimir and Moroni, Lorenzo and Ozbolat, Ibrahim T}, title = {The bioprinting roadmap}, series = {Biofabrication}, volume = {12}, journal = {Biofabrication}, number = {2}, doi = {10.1088/1758-5090/ab5158}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-254027}, year = {2020}, abstract = {This bioprinting roadmap features salient advances in selected applications of the technique and highlights the status of current developments and challenges, as well as envisioned advances in science and technology, to address the challenges to the young and evolving technique.

The emerging application of printing-in-space and an overview of bioprinting technologies are also included in this roadmap. Due to the rapid pace of methodological advancements in bioprinting techniques and wide-ranging applications, the direction in which the field should advance is not immediately clear. This bioprinting roadmap addresses this unmet need by providing a comprehensive summary and recommendations useful to experienced researchers and newcomers to the field.}, language = {en} } @article{BenhalevyGuptaDananetal.2017, author = {Benhalevy, Daniel and Gupta, Sanjay K. and Danan, Charles H. and Ghosal, Suman and Sun, Hong-Wei and Kazemeier, Hinke G. and Paeschke, Katrin and Hafner, Markus and Juranek, Stefan A.}, title = {The Human CCHC-type Zinc Finger Nucleic Acid-Binding Protein Binds G-Rich Elements in Target mRNA Coding Sequences and Promotes Translation}, series = {Cell Reports}, volume = {18}, journal = {Cell Reports}, number = {12}, doi = {10.1016/j.celrep.2017.02.080}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-171122}, pages = {2979-2990}, year = {2017}, abstract = {The CCHC-type zinc finger nucleic acid-binding protein (CNBP/ZNF9) is conserved in eukaryotes and is essential for embryonic development in mammals. It has been implicated in transcriptional, as well as post-transcriptional, gene regulation; however, its nucleic acid ligands and molecular function remain elusive. Here, we use multiple systems-wide approaches to identify CNBP targets and function. We used photoactivatable ribonucleoside-enhanced crosslinking and immunoprecipitation (PAR-CLIP) to identify 8,420 CNBP binding sites on 4,178 mRNAs. CNBP preferentially bound G-rich elements in the target mRNA coding sequences, most of which were previously found to form G-quadruplex and other stable structures in vitro. Functional analyses, including RNA sequencing, ribosome profiling, and quantitative mass spectrometry, revealed that CNBP binding did not influence target mRNA abundance but rather increased their translational efficiency. Considering that CNBP binding prevented G-quadruplex structure formation in vitro, we hypothesize that CNBP is supporting translation by resolving stable structures on mRNAs.}, language = {en} }
