A diverse array of AMPAR signalling complexes are established by receptor auxiliary subunits, which associate with the AMPAR in various combinations to modulate trafficking, gating and synaptic strength2. However, their mechanisms of action are poorly understood. Here we determine cryo-electron microscopy structures of the heteromeric GluA1–GluA2 receptor assembled with both TARP-γ8 and CNIH2, the predominant AMPAR complex in the forebrain, in both resting and active states. Two TARP-γ8 and two CNIH2 subunits insert at distinct sites beneath the ligand-binding domains of the receptor, with site-specific lipids shaping each interaction and affecting the gating regulation of the AMPARs. Activation of the receptor leads to asymmetry between GluA1 and GluA2 along the ion conduction path and an outward expansion of the channel triggers counter-rotations of both auxiliary subunit pairs, promoting the active-state conformation. In addition, both TARP-γ8 and CNIH2 pivot towards the pore exit upon activation, extending their reach for cytoplasmic receptor elements. CNIH2 achieves this through its uniquely extended M2 helix, which has transformed this endoplasmic reticulum-export factor into a powerful AMPAR modulator that is capable of providing hippocampal pyramidal neurons with their integrative synaptic properties.

The hippocampal CA3-CA1 pyramidal cell synaptic connection shows an input-side dependent asymmetry where the hemispheric location of the presynaptic CA3 neuron determines the synaptic properties. Left-input synapses terminating on apical dendrites in stratum radiatum have a higher density of NMDA receptor subunit GluN2B, a lower density of AMPA receptor subunit GluA1 and smaller areas with less often perforated PSDs. On the other hand, left-input synapses terminating on basal dendrites in stratum oriens have lower GluN2B densities than right-input ones. Apical and basal synapses further employ different signaling pathways involved in LTP. SDS-digested freeze-fracture replica labeling can visualize synaptic membrane proteins with high sensitivity and resolution, and has been used to reveal the asymmetry at the electron microscopic level. However, it requires time-consuming manual demarcation of the synaptic surface for quantitative measurements. To facilitate the analysis of replica labeling, I first developed a software named Darea, which utilizes deep-learning to automatize this demarcation. With Darea I characterized the synaptic distribution of NMDA and AMPA receptors as well as the voltage-gated Ca2+ channels in CA1 stratum radiatum and oriens. Second, I explored the role of GluN2B and its carboxy-terminus in the establishment of input-side dependent hippocampal asymmetry. In conditional knock-out mice lacking GluN2B expression in CA1 and GluN2B-2A swap mice, where GluN2B carboxy-terminus was exchanged to that of GluN2A, no significant asymmetries of GluN2B, GluA1 and PSD area were detected. We further discovered a previously unknown functional asymmetry of GluN2A, which was also lost in the swap mouse. These results demonstrate that GluN2B carboxy-terminus plays a critical role in normal formation of input-side dependent asymmetry.","lang":"eng"}],"has_accepted_license":"1","file_date_updated":"2022-07-02T22:30:04Z","publication_status":"published","publication_identifier":{"issn":["2663-337X"]},"related_material":{"record":[{"status":"public","relation":"part_of_dissertation","id":"9756"},{"id":"9437","status":"public","relation":"part_of_dissertation"},{"relation":"part_of_dissertation","status":"public","id":"8532"},{"relation":"part_of_dissertation","status":"public","id":"612"}]},"year":"2021","status":"public","degree_awarded":"PhD","date_published":"2021-06-01T00:00:00Z","publisher":"Institute of Science and Technology Austria","alternative_title":["ISTA Thesis"],"article_processing_charge":"No","doi":"10.15479/at:ista:9562","type":"dissertation","_id":"9562","date_updated":"2023-09-11T12:55:53Z","ddc":["570"],"page":"124"},{"external_id":{"isi":["000665644000048"]},"year":"2021","isi":1,"acknowledgement":"The research is funded by Higher Education Commission (HEC) Pakistan under start-up research grant program (SRGP) Project no. 2454.","date_published":"2021-06-18T00:00:00Z","publication":"RSC Advances","status":"public","type":"journal_article","date_updated":"2023-08-08T14:23:21Z","_id":"9569","publisher":"Royal Society of Chemistry","doi":"10.1039/d1ra03428f","article_processing_charge":"No","quality_controlled":"1","ddc":["540"],"page":"21702-21715","file":[{"file_id":"9596","date_created":"2021-06-23T13:09:34Z","file_size":2114557,"date_updated":"2021-06-23T13:09:34Z","creator":"asandaue","relation":"main_file","checksum":"cd582d67ace7151078e46b3a896871a9","file_name":"2021_RSCAdvances_Dar.pdf","success":1,"content_type":"application/pdf","access_level":"open_access"}],"department":[{"_id":"KiMo"}],"month":"06","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","issue":"35","citation":{"apa":"Dar, M.

We adopted the wet chemical procedure, using various contents of Fe3O4 (magnetite) from 0–100% for making two-dimensional graphene–Fe3O4 nanohybrids. The homogeneous dispersal of Fe3O4 nanoparticles decorated on the graphene surface combined with their biocompatibility and high thermal conductivity make them an excellent material for magnetic hyperthermia. The morphological and magnetic properties of the nanohybrids were studied using scanning electron microscopy (SEM) and a vibrating sample magnetometer (VSM), respectively. The smart magnetic platforms were exposed to an alternating current (AC) magnetic field of 633 kHz and of strength 9.1 mT for studying their hyperthermic performance. The localized antitumor effects were investigated with artificial neural network modeling. A neural net time-series model was developed for the assessment of the best nanohybrid composition to serve the purpose with an accuracy close to 100%. Six Nonlinear Autoregressive with External Input (NARX) models were obtained, one for each of the components. The assessment of the accuracy of the predicted results has been done on the basis of Mean Squared Error (MSE). The highest Mean Squared Error value was obtained for the nanohybrid containing 45% magnetite and 55% graphene (F45G55) in the training phase i.e., 0.44703, which is where the model achieved optimal results after 71 epochs. The F45G55 nanohybrid was found to be the best for hyperthermia applications in low dosage with the highest specific absorption rate (SAR) and mean squared error values.","lang":"eng"}],"intvolume":"        11","has_accepted_license":"1"},{"main_file_link":[{"url":"https://arxiv.org/abs/2006.01275","open_access":"1"}],"quality_controlled":"1","_id":"9570","date_updated":"2023-08-08T14:08:08Z","type":"journal_article","article_processing_charge":"No","doi":"10.1103/PhysRevB.103.235201","publisher":"American Physical Society","acknowledgement":"We acknowledge insightful discussions with K.

The baseline variant of QSGD provides strong theoretical guarantees, however, for practical purposes, the authors proposed a heuristic variant which we call QSGDinf, which demonstrated impressive empirical gains for distributed training of large neural networks. In this paper, we build on this work to propose a new gradient quantization scheme, and show that it has both stronger theoretical guarantees than QSGD, and matches and exceeds the empirical performance of the QSGDinf heuristic and of other compression methods."}],"has_accepted_license":"1","date_created":"2021-06-20T22:01:33Z","article_type":"original","volume":22,"oa_version":"Published Version","title":"NUQSGD: Provably communication-efficient data-parallel SGD via nonuniform quantization","day":"01","scopus_import":"1","author":[{"first_name":"Ali","full_name":"Ramezani-Kebrya, Ali","last_name":"Ramezani-Kebrya"},{"first_name":"Fartash","full_name":"Faghri, Fartash","last_name":"Faghri"},{"full_name":"Markov, Ilya","last_name":"Markov","first_name":"Ilya"},{"last_name":"Aksenov","id":"2980135A-F248-11E8-B48F-1D18A9856A87","full_name":"Aksenov, Vitalii","first_name":"Vitalii"},{"full_name":"Alistarh, Dan-Adrian","id":"4A899BFC-F248-11E8-B48F-1D18A9856A87","last_name":"Alistarh","orcid":"0000-0003-3650-940X","first_name":"Dan-Adrian"},{"first_name":"Daniel M.","last_name":"Roy","full_name":"Roy, Daniel M."}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"A.

We show a construction of an arbitrarily large odd-sized point set that allows Bob to obtain almost 3/4 of the total weight. This construction answers a question asked by Matsumoto, Nakamigawa, and Sakuma in [Graphs and Combinatorics, 36/1 (2020)].

However, neither parent-of-origin-specific transcription nor imprints have been comprehensively mapped at the blastocyst stage of preimplantation development. Here, we address this by integrating transcriptomic and epigenomic approaches in mouse preimplantation embryos. We find that seventy-one genes exhibit previously unreported parent-of-origin-specific expression in blastocysts (nBiX: novel blastocyst-imprinted expressed). Uniparental expression of nBiX genes disappears soon after implantation. Micro-whole-genome bisulfite sequencing (µWGBS) of individual uniparental blastocysts detects 859 DMRs. We further find that 16% of nBiX genes are associated with a DMR, whereas most are associated with parentally-biased H3K27me3, suggesting a role for Polycomb-mediated imprinting in blastocysts. nBiX genes are clustered: five clusters contained at least one published imprinted gene, and five clusters exclusively contained nBiX genes. These data suggest that early development undergoes a complex program of stage-specific imprinting involving different tiers of regulation.","lang":"eng"}],"volume":12,"article_type":"original","date_created":"2021-06-27T22:01:46Z","author":[{"last_name":"Santini","full_name":"Santini, Laura","first_name":"Laura"},{"full_name":"Halbritter, Florian","last_name":"Halbritter","first_name":"Florian"},{"first_name":"Fabian","full_name":"Titz-Teixeira, Fabian","last_name":"Titz-Teixeira"},{"first_name":"Toru","full_name":"Suzuki, Toru","last_name":"Suzuki"},{"first_name":"Maki","last_name":"Asami","full_name":"Asami, Maki"},{"first_name":"Xiaoyan","full_name":"Ma, Xiaoyan","last_name":"Ma"},{"first_name":"Julia","full_name":"Ramesmayer, Julia","last_name":"Ramesmayer"},{"last_name":"Lackner","full_name":"Lackner, Andreas","first_name":"Andreas"},{"first_name":"Nick","last_name":"Warr","full_name":"Warr, Nick"},{"first_name":"Florian","orcid":"0000-0002-7462-0048","id":"48EA0138-F248-11E8-B48F-1D18A9856A87","full_name":"Pauler, Florian","last_name":"Pauler"},{"last_name":"Hippenmeyer","id":"37B36620-F248-11E8-B48F-1D18A9856A87","full_name":"Hippenmeyer, Simon","orcid":"0000-0003-2279-1061","first_name":"Simon"},{"full_name":"Laue, Ernest","last_name":"Laue","first_name":"Ernest"},{"full_name":"Farlik, Matthias","last_name":"Farlik","first_name":"Matthias"},{"last_name":"Bock","full_name":"Bock, Christoph","first_name":"Christoph"},{"last_name":"Beyer","full_name":"Beyer, Andreas","first_name":"Andreas"},{"first_name":"Anthony C.F.","last_name":"Perry","full_name":"Perry, Anthony C.F."},{"full_name":"Leeb, Martin","last_name":"Leeb","first_name":"Martin"}],"day":"12","scopus_import":"1","title":"Genomic imprinting in mouse blastocysts is predominantly associated with H3K27me3","oa_version":"Published Version","issue":"1","citation":{"ista":"Santini L, Halbritter F, Titz-Teixeira F, Suzuki T, Asami M, Ma X, Ramesmayer J, Lackner A, Warr N, Pauler F, Hippenmeyer S, Laue E, Farlik M, Bock C, Beyer A, Perry ACF, Leeb M. 2021.

This strengthens a result of Bousquet, Lagoutte, and Thomassé, who proved the analogous result for unordered graphs.\r\nA key idea of the above paper was to show that any unordered graph on n vertices that does not contain an induced path of size k, and whose maximum degree is at most c(k)n for some small c(k) > 0, contains two disjoint linear size subsets with no edge between them. This approach fails for ordered graphs, because the analogous statement is false for k ≥ 3, by a construction of Fox.

MADM applications include the analysis of lineage, single-cell morphology and physiology, genomic imprinting phenotypes, and dissection of cell-autonomous gene functions in vivo in health and disease. Yet, MADM can only be applied to <25% of all mouse genes on select chromosomes to date. To overcome this limitation, we generate transgenic mice with knocked-in MADM cassettes near the centromeres of all 19 autosomes and validate their use across organs. With this resource, >96% of the entire mouse genome can now be subjected to single-cell genetic mosaic analysis. Beyond a proof of principle, we apply our MADM library to systematically trace sister chromatid segregation in distinct mitotic cell lineages. We find striking chromosome-specific biases in segregation patterns, reflecting a putative mechanism for the asymmetric segregation of genetic determinants in somatic stem cell division."}],"intvolume":"        35","acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"PreCl"}],"isi":1,"year":"2021","external_id":{"isi":["000664463600016"]},"related_material":{"link":[{"relation":"press_release","url":"https://ist.ac.at/en/news/boost-for-mouse-genetic-analysis/","description":"News on IST Homepage"}]},"ec_funded":1,"acknowledgement":"We thank the Bioimaging, Life Science, and Pre-Clinical Facilities at IST Austria; M.P.

Allowing r and k to vary, we obtain a 2-parameter family of spaces that grow larger when r increases or k decreases, called the multicover bifiltration. Motivated by the problem of computing the homology of this bifiltration, we introduce two closely related combinatorial bifiltrations, one polyhedral and the other simplicial, which are both topologically equivalent to the multicover bifiltration and far smaller than a Čech-based model considered in prior work of Sheehy. Our polyhedral construction is a bifiltration of the rhomboid tiling of Edelsbrunner and Osang, and can be efficiently computed using a variant of an algorithm given by these authors as well. Using an implementation for dimension 2 and 3, we provide experimental results. Our simplicial construction is useful for understanding the polyhedral construction and proving its correctness.

Here, for a two-dimensional system of ultracold fermions, we calculate the first and second sound velocities across the whole BCS-BEC crossover, and we analyze the system response to an external perturbation. In the low-temperature regime we reproduce the recent measurements [Phys. Rev. Lett. 124, 240403 (2020)] of the first sound velocity, which, due to the decoupling of density and entropy fluctuations, is the sole mode excited by a density probe. Conversely, a heat perturbation excites only the second sound, which, being sensitive to the superfluid depletion, vanishes in the deep BCS regime and jumps discontinuously to zero at the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the modes occurs only in the finite-temperature BEC regime, where our theory converges to the purely bosonic results.","lang":"eng"}],"intvolume":"       103","publication_identifier":{"issn":["24699926"],"eissn":["24699934"]},"publication_status":"published","author":[{"first_name":"A.","last_name":"Tononi","full_name":"Tononi, A."},{"first_name":"Alberto","orcid":"0000-0001-6110-2359","id":"9d13b3cb-30a2-11eb-80dc-f772505e8660","full_name":"Cappellaro, Alberto","last_name":"Cappellaro"},{"orcid":"0000-0001-8823-9777","first_name":"Giacomo","full_name":"Bighin, Giacomo","id":"4CA96FD4-F248-11E8-B48F-1D18A9856A87","last_name":"Bighin"},{"full_name":"Salasnich, L.","last_name":"Salasnich","first_name":"L."}],"scopus_import":"1","day":"01","title":"Propagation of first and second sound in a two-dimensional Fermi superfluid","oa_version":"Preprint","volume":103,"article_type":"letter_note","date_created":"2021-06-27T22:01:49Z","status":"public","publication":"Physical Review A","date_published":"2021-06-01T00:00:00Z","acknowledgement":"G.B. acknowledges support from the Austrian Science Fund (FWF), under Project No. M2641-N27.

Numerous analyses conducted to date have clearly identified measures that need to be taken to improve research rigor. Supported through the European Union's Innovative Medicines Initiative, the EQIPD consortium has developed a novel preclinical research quality system that can be applied in both public and private sectors and is free for anyone to use. The EQIPD Quality System was designed to be suited to boost innovation by ensuring the generation of robust and reliable preclinical data while being lean, effective and not becoming a burden that could negatively impact the freedom to explore scientific questions. EQIPD defines research quality as the extent to which research data are fit for their intended use. Fitness, in this context, is defined by the stakeholders, who are the scientists directly involved in the research, but also their funders, sponsors, publishers, research tool manufacturers and collaboration partners such as peers in a multi-site research project. The essence of the EQIPD Quality System is the set of 18 core requirements that can be addressed flexibly, according to user-specific needs and following a user-defined trajectory. The EQIPD Quality System proposes guidance on expectations for quality-related measures, defines criteria for adequate processes (i.e., performance standards) and provides examples of how such measures can be developed and implemented. However, it does not prescribe any pre-determined solutions. EQIPD has also developed tools (for optional use) to support users in implementing the system and assessment services for those research units that successfully implement the quality system and seek formal accreditation. Building upon the feedback from users and continuous improvement, a sustainable EQIPD Quality System will ultimately serve the entire community of scientists conducting non-regulated preclinical research, by helping them generate reliable data that are fit for their intended use.","lang":"eng"}],"file_date_updated":"2021-06-28T11:35:30Z","publication_identifier":{"eissn":["2050084X"]},"publication_status":"published","month":"05","department":[{"_id":"PreCl"}],"file":[{"relation":"main_file","checksum":"885b746051a7a6b6e24e3d2781a48fde","success":1,"file_name":"2021_ELife_Bespalov.pdf","access_level":"open_access","content_type":"application/pdf","file_id":"9609","date_created":"2021-06-28T11:35:30Z","file_size":2500720,"creator":"asandaue","date_updated":"2021-06-28T11:35:30Z"}],"oa":1,"language":[{"iso":"eng"}],"citation":{"short":"A.

By doing so, they hope to reduce the number of coupons that must be sampled by each collector in order to obtain a full set. This extension is natural when considering real-world manifestations of the coupon collector phenomenon, and has been remarked upon and studied empirically (Hayes and Hannigan 2006, Ahmad et al. 2014, Delmarcelle 2019).\r\n\r\nWe provide the first theoretical analysis for such a scenario. We find that “coupon collecting with friends” can indeed significantly reduce the number of coupons each collector must sample, and raises interesting connections to the more traditional variants of the problem. While our analysis is in most cases asymptotically tight, there are several open questions raised, regarding finer-grained analysis of both “coupon collecting with friends,” and of a long-studied variant of the original problem in which a collector requires multiple full sets of coupons.","lang":"eng"}],"intvolume":"     12810","publication_identifier":{"issn":["0302-9743"],"isbn":["9783030795269"],"eissn":["1611-3349"],"eisbn":["9783030795276"]},"publication_status":"published","file_date_updated":"2021-07-01T11:21:40Z","month":"06","department":[{"_id":"DaAl"}],"file":[{"relation":"main_file","checksum":"fe37fb9af3f5016c1084af9d6e7109bd","file_name":"Population_Coupon_Collector.pdf","access_level":"open_access","content_type":"application/pdf","file_id":"9621","date_created":"2021-07-01T11:21:40Z","file_size":319728,"date_updated":"2021-07-01T11:21:40Z","creator":"pdavies"}],"oa":1,"language":[{"iso":"eng"}],"citation":{"ista":"Alistarh D-A, Davies P. 2021.

In large cells like oocytes, these reorganizations become crucial in patterning the oocyte for later stages of embryonic development. Ascidians oocytes reorganize their cytoplasm (ooplasm) in a spectacular manner. Ooplasmic reorganization is initiated at fertilization with the contraction of the actomyosin cortex along the animal-vegetal axis of the oocyte, driving the accumulation of cortical endoplasmic reticulum (cER), maternal mRNAs associated to it and a mitochondria-rich subcortical layer – the myoplasm – in a region of the vegetal pole termed contraction pole (CP). Here we have used the species Phallusia mammillata to investigate the changes in cell shape that accompany these reorganizations and the mechanochemical mechanisms underlining CP formation.\r\nWe report that the length of the animal-vegetal (AV) axis oscillates upon fertilization: it first undergoes a cycle of fast elongation-lengthening followed by a slow expansion of mainly the vegetal pole (VP) of the cell. We show that the fast oscillation corresponds to a dynamic polarization of the actin cortex as a result of a fertilization-induced increase in cortical tension in the oocyte that triggers a rupture of the cortex at the animal pole and the establishment of vegetal-directed cortical flows. These flows are responsible for the vegetal accumulation of actin causing the VP to flatten. \r\nWe find that the slow expansion of the VP, leading to CP formation, correlates with a relaxation of the vegetal cortex and that the myoplasm plays a role in the expansion. We show that the myoplasm is a solid-like layer that buckles under compression forces arising from the contracting actin cortex at the VP. Straightening of the myoplasm when actin flows stops, facilitates the expansion of the VP and the CP. Altogether, our results present a previously unrecognized role for the myoplasm in ascidian ooplasmic segregation. \r\n"}],"acknowledged_ssus":[{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"NanoFab"},{"_id":"M-Shop"}],"has_accepted_license":"1","date_created":"2021-07-01T14:50:17Z","oa_version":"Published Version","title":"Fertilization-induced deformations are controlled by the actin cortex and a mitochondria-rich subcortical layer in ascidian oocytes","author":[{"full_name":"Caballero Mancebo, Silvia","id":"2F1E1758-F248-11E8-B48F-1D18A9856A87","last_name":"Caballero Mancebo","orcid":"0000-0002-5223-3346","first_name":"Silvia"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","citation":{"apa":"Caballero Mancebo, S.

Here, we promoted the TE performance of n-type SnSe polycrystals through bandgap engineering and vacancy compensation. We found that PbTe can significantly reduce the wide bandgap of SnSe to reduce the impurity transition energy, largely enhancing the carrier concentration. Also, PbTe-induced crystal symmetry promotion increases the carrier mobility, preserving large Seebeck coefficient. Consequently, a maximum ZT of ∼1.4 at 793 K is obtained in Br doped SnSe–13%PbTe. Furthermore, we found that extra Sn in n-type SnSe can compensate for the intrinsic Sn vacancies and form electron donor-like metallic Sn nanophases. The Sn nanophases near the grain boundary could also reduce the intergrain energy barrier which largely enhances the carrier mobility. As a result, a maximum ZT value of ∼1.7 at 793 K and an average ZT (ZTave) of ∼0.58 in 300–793 K are achieved in Br doped Sn1.08Se–13%PbTe. Our findings provide a novel strategy to promote the TE performance in wide-bandgap semiconductors.","lang":"eng"}],"volume":20,"article_type":"original","date_created":"2021-07-04T22:01:24Z","author":[{"full_name":"Su, Lizhong","last_name":"Su","first_name":"Lizhong"},{"full_name":"Hong, Tao","last_name":"Hong","first_name":"Tao"},{"first_name":"Dongyang","full_name":"Wang, Dongyang","last_name":"Wang"},{"full_name":"Wang, Sining","last_name":"Wang","first_name":"Sining"},{"first_name":"Bingchao","full_name":"Qin, Bingchao","last_name":"Qin"},{"last_name":"Zhang","full_name":"Zhang, Mengmeng","first_name":"Mengmeng"},{"first_name":"Xiang","last_name":"Gao","full_name":"Gao, Xiang"},{"first_name":"Cheng","orcid":"0000-0002-9515-4277","last_name":"Chang","id":"9E331C2E-9F27-11E9-AE48-5033E6697425","full_name":"Chang, Cheng"},{"first_name":"Li Dong","last_name":"Zhao","full_name":"Zhao, Li Dong"}],"day":"03","scopus_import":"1","title":"Realizing high doping efficiency and thermoelectric performance in n-type SnSe polycrystals via bandgap engineering and vacancy compensation","oa_version":"None","date_published":"2021-06-03T00:00:00Z","acknowledgement":"This work was supported by National Natural Science Foundation of China (51772012), National Key Research and Development Program of China (2018YFA0702100 and 2018YFB0703600), the Beijing Natural Science Foundation (JQ18004).
