The goal is to present the bounds with minimal notation, making the results accessible to a broad community and stimulating further research in the area.\r\n\r\nSpecifically, we first describe a lower bound on the symbolic complexity of computing strongly connected components, which can be extended to show lower bounds for fundamental model-checking questions in graphs, published in [CDHL16b]. Second we present a conditional lower bound for disjunctive safety problems on graphs from [CDHL18] in the RAM model of computation. This bound can be modified to give conditional lower bounds for disjunctive objectives for reachability, Büchi, coBüchi and Rabin objectives in MDPs.

However, hydrocyanation reactions using hydrogen cyanide (HCN) or similarly toxic reagents on laboratory scale can be particularly challenging due to their hazardous nature. In addition, such processes typically require air- and temperature-sensitive Ni(0) precatalysts, further reducing the operational simplicity of this transformation. Herein, we report a HCN-free transfer hydrocyanation of alkenes and alkynes that employs commercially available aliphatic nitriles as sacrificial HCN donors in combination with a catalytic amount of air-stable and inexpensive NiCl2 as a precatalyst and a cocatalytic Lewis acid. The scalability and robustness of the catalytic process were demonstrated by the hydrocyanation of α-methylstyrene on a 100 mmol scale (11.4 g of product obtained) using 1 mol % of the Ni catalyst. In addition, the feasibility of the dehydrocyanation protocol using the air-stable Ni(II) precatalyst and norbornadiene as a sacrificial acceptor was showcased by the selective conversion of an aliphatic nitrile into the corresponding alkene.","lang":"eng"}],"page":"1165-1173","oa":1,"month":"02","type":"journal_article","citation":{"ama":"Reisenbauer J, Bhawal BN, Jelmini N, Morandi B.

These architectures typically have a vast number of weights and need to be trained on massive datasets; hence, they are not suitable for their use in low-data regimes. In this work, we propose a simple yet effective framework to improve generalization from small amounts of data. We augment modern CNNs with fully-connected (FC) layers and show the massive impact this architectural change has in low-data regimes. We further present an online joint knowledge-distillation method to utilize the extra FC layers at train time but avoid them during test time. This allows us to improve the generalization of a CNN-based model without any increase in the number of weights at test time. We perform classification experiments for a large range of network backbones and several standard datasets on supervised learning and active learning. Our experiments significantly outperform the networks without fully-connected layers, reaching a relative improvement of up to 16% validation accuracy in the supervised setting without adding any extra parameters during inference."}],"_id":"18876"},{"volume":375,"year":"2022","publication":"Transactions of the American Mathematical Society","scopus_import":"1","intvolume":"       375","doi":"10.1090/tran/8732","issue":"9","title":"Integral points on the congruent number curve","author":[{"full_name":"Chan, Yik Tung","first_name":"Yik Tung","orcid":"0000-0001-8467-4106","id":"c4c0afc8-9262-11ed-9231-d8b0bc743af1","last_name":"Chan"}],"date_created":"2025-04-05T10:50:56Z","article_type":"original","date_published":"2022-09-01T00:00:00Z","OA_type":"green","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","external_id":{"arxiv":["2004.03331"]},"extern":"1","publication_status":"published","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2004.03331"}],"status":"public","publication_identifier":{"issn":["0002-9947"],"eissn":["1088-6850"]},"day":"01","arxiv":1,"OA_place":"repository","month":"09","type":"journal_article","citation":{"apa":"Chan, S.

We found that methylation of G2922 is needed for assembly and efficient nuclear export of the large subunit. Critically, we identified single amino acid changes in Nog2 that completely bypass dependence on G2922 methylation and used cryoelectron microscopy to directly visualize how methylation flips Gm2922 into the active site channel of Nog2. This work demonstrates that a single RNA modification is a critical checkpoint in ribosome biogenesis, suggesting that such modifications can play an important role in regulation and assembly of macromolecular machines.","lang":"eng"}],"keyword":["Molecular Biology","Structural Biology"],"_id":"15131","date_updated":"2024-06-04T06:27:09Z","language":[{"iso":"eng"}],"oa_version":"Published Version","publisher":"Springer Nature","quality_controlled":"1","date_created":"2024-03-20T10:41:45Z","author":[{"full_name":"Yelland, James N.","first_name":"James N.","last_name":"Yelland"},{"orcid":"0000-0003-0456-0753","last_name":"Bravo","id":"96aecfa5-8931-11ee-af30-aa6a5d6eee0e","full_name":"Bravo, Jack Peter Kelly","first_name":"Jack Peter Kelly"},{"first_name":"Joshua J.","full_name":"Black, Joshua J.","last_name":"Black"},{"full_name":"Taylor, David W.","first_name":"David W.","last_name":"Taylor"},{"last_name":"Johnson","first_name":"Arlen W.","full_name":"Johnson, Arlen W."}],"title":"A single 2′-O-methylation of ribosomal RNA gates assembly of a functional ribosome","article_type":"original","date_published":"2022-12-19T00:00:00Z","volume":30,"scopus_import":"1","pmid":1,"publication":"Nature Structural & Molecular Biology","year":"2022","intvolume":"        30","doi":"10.1038/s41594-022-00891-8","article_processing_charge":"Yes (in subscription journal)","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_status":"published","extern":"1","external_id":{"pmid":["36536102"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41594-022-00891-8"}],"status":"public","publication_identifier":{"issn":["1545-9993"],"eissn":["1545-9985"]},"day":"19"},{"publisher":"Elsevier","quality_controlled":"1","oa_version":"None","language":[{"iso":"eng"}],"date_updated":"2024-10-14T12:34:11Z","_id":"15132","keyword":["Biomedical Engineering","Bioengineering","Biotechnology"],"abstract":[{"text":"Clustered regularly interspaced short palindromic repeats - CRISPR-associated protein (CRISPR-Cas) systems are a critical component of the bacterial adaptive immune response.

Here, we report cryo-EM structures of the core DISARM complex, DrmAB, both alone and in complex with an unmethylated phage DNA mimetic. These structures reveal that DrmAB core complex is autoinhibited by a trigger loop (TL) within DrmA and binding to DNA substrates containing a 5′ overhang dislodges the TL, initiating a long-range structural rearrangement for DrmAB activation.

Two of the most prevalent CRISPR-Cas systems include type I and type III. Interestingly, the type I-D interference proteins contain characteristic features of both type I and type III systems. Here, we present the structures of type I-D Cascade bound to both a double-stranded (ds)DNA and a single-stranded (ss)RNA target at 2.9 and 3.1 Å, respectively. We show that type I-D Cascade is capable of specifically binding ssRNA and reveal how PAM recognition of dsDNA targets initiates long-range structural rearrangements that likely primes Cas10d for Cas3′ binding and subsequent non-target strand DNA cleavage. These structures allow us to model how binding of the anti-CRISPR protein AcrID1 likely blocks target dsDNA binding via competitive inhibition of the DNA substrate engagement with the Cas10d active site. This work elucidates the unique mechanisms used by type I-D Cascade for discrimination of single-stranded and double stranded targets. Thus, our data supports a model for the hybrid nature of this complex with features of type III and type I systems.","lang":"eng"}],"keyword":["General Physics and Astronomy","General Biochemistry","Genetics and Molecular Biology","General Chemistry","Multidisciplinary"],"_id":"15134","type":"journal_article","month":"05","citation":{"ama":"Schwartz EA, McBride TM, Bravo JPK, et al.

Here we used kinetics-guided cryo-electron microscopy to determine the structure of Cas9 at different stages of mismatch cleavage. We observed a distinct, linear conformation of the guide RNA–DNA duplex formed in the presence of mismatches, which prevents Cas9 activation. Although the canonical kinked guide RNA–DNA duplex conformation facilitates DNA cleavage, we observe that substrates that contain mismatches distal to the protospacer adjacent motif are stabilized by reorganization of a loop in the RuvC domain. Mutagenesis of mismatch-stabilizing residues reduces off-target DNA cleavage but maintains rapid on-target DNA cleavage.

Radiation from such objects is expected to be highly polarized due to birefringence of plasma and vacuum associated with propagation of photons in the presence of the strong magnetic field. Here we present results of the observations of Cen X-3 performed with the Imaging X-ray Polarimetry Explorer. The source exhibited significant flux variability and was observed in two states different by a factor of ∼20 in flux. In the low-luminosity state, no significant polarization was found in either pulse phase-averaged (with a 3σ upper limit of 12%) or phase-resolved (the 3σ upper limits are 20%–30%) data. In the bright state, the polarization degree of 5.8% ± 0.3% and polarization angle of 49fdg6 ± 1fdg5 with a significance of about 20σ were measured from the spectropolarimetric analysis of the phase-averaged data. The phase-resolved analysis showed a significant anticorrelation between the flux and the polarization degree, as well as strong variations of the polarization angle. The fit with the rotating vector model indicates a position angle of the pulsar spin axis of about 49° and a magnetic obliquity of 17°. The detected relatively low polarization can be explained if the upper layers of the neutron star surface are overheated by the accreted matter and the conversion of the polarization modes occurs within the transition region between the upper hot layer and a cooler underlying atmosphere. A fraction of polarization signal can also be produced by reflection of radiation from the neutron star surface and the accretion curtain."}],"oa":1,"citation":{"short":"S.S. Tsygankov, V.

The observed degree of linear polarization of ~10% is far below theoretical expectations for this object, and stays low throughout the spin cycle of the pulsar. Both the degree and angle of polarization exhibit variability with the pulse phase, allowing us to measure the pulsar spin position angle 57(2) deg and the magnetic obliquity 12(4) deg, which is an essential step towards detailed modelling of the intrinsic emission of X-ray pulsars. Combining our results with the optical polarimetric data, we find that the spin axis of the neutron star and the angular momentum of the binary orbit are misaligned by at least ~20 deg, which is a strong argument in support of the models explaining the stability of the observed superorbital variability with the precession of the neutron star.","lang":"eng"}],"_id":"15204","keyword":["Astronomy

Polarization measurements could provide information on their magnetic fields and surface properties. We observed polarized x-rays from the magnetar 4U 0142+61 using the Imaging X-ray Polarimetry Explorer and found a linear polarization degree of 13.5 ± 0.8% averaged over the 2– to 8–kilo–electron volt band. The polarization changes with energy: The degree is 15.0 ± 1.0% at 2 to 4 kilo–electron volts, drops below the instrumental sensitivity ~4 to 5 kilo–electron volts, and rises to 35.2 ± 7.1% at 5.5 to 8 kilo–electron volts. The polarization angle also changes by 90° at ~4 to 5 kilo–electron volts. These results are consistent with a model in which thermal radiation from the magnetar surface is reprocessed by scattering off charged particles in the magnetosphere.","lang":"eng"}],"_id":"15205","keyword":["Multidisciplinary"],"arxiv":1}]
