description: Comparative modelling of a structurally uncharacterised protein can generally produce a good 3D model if the template shares global sequence identity of ≥30% with the target protein. However, once the sequence identity falls below 30% (“Twilight zone”), the model quality can deteriorate significantly.
This research explores the use of CATH-Gene3D functional families (FunFams) to guide the template selection process. FunFams are clusters of homologous domain sequences likely to share similar structures and functions.

FunFam clusters are generated using the FunFHMMer method which identifies similarities in sequence patterns (highly conserved positions and specificity-determining positions) likely to be associated with conserved structural and functional properties. These patterns have been shown to be a more reliable indicator of structural similarity than global sequence identity for distant homologues in the “Twilight Zone”. CATH-Gene3D is a classification of more than 235,858 domain structures and 35 million domain sequences. All the sequences in CATH-Gene3D have been clustered into functional families by FunFHMMer. The validated structural coherence of these groups indicates that they have the potential to be used for the modelling of “Twilight zone” proteins.

Different template selection methods were compared for a benchmark dataset that consists of 9198 non-redundant CATH sequences. 3D models were built using the MODELLER algorithm. The qualities of the models were assessed by doing structural comparison with native structures using the SSAP algorithm. A pipeline exploiting CATH-Gene3D FunFams for template selection produces more, good quality models than  for close homologs (sequence identity ≥30%) and remote homologues.

The FunFam-based modelling pipeline has been applied to model human domain sequences that do not have any known structural information. The pipeline generates 24% and 10% more models compared to the classical BLAST and PSIBLAST approaches.

description: Clausius-Mossotti approximation is extended to describe the measured magnetic moment of an ellipsoidal sample containing magnetic or nonmagnetic ellipsoidal inclusions and magnetic or nonmagnetic matrix. The magnetic field in the matrix and inclusions is calculated. The magnetic energy of a system is calculated also. The equilibrium shape of a pore in a ferromagnetic sample is investigated. The phenomenon of cavitation in porous ferromagnetic samples is described. The model is applied to calculate magnetic properties of granular superconductors. The effective electric conductivity of a sample of a composite material, containing an arbitrary number of differently ordered distributions of ellipsoidal inclusions is calculated. Effective conductivity of a composite material, consisting of fibers of high conductivity and a matrix of low conductivity is discussed. Concentrated electric field in the vicinity of the ends of a conductive nanofiber in a composite material is calculated. The high quantity of this field is of an extreme importance to provide the proper functioning of monitors, based on conductive nanofibers in dielectric media.

description: Manuscripts have a complex development process with multiple influencing factors. Reconstructing this process is difficult without large-scale, comparable data on different versions of manuscripts. Preprints are increasingly available and may provide access to the earliest manuscript versions. Here, we matched 6,024 preprint-publication pairs across multiple fields and examined changes in their reference lists between the manuscript versions as one aspect of manuscripts' development. We also qualitatively analysed the context of references to investigate the potential reasons for changes. We found that 90 percent of references were unchanged between versions and 8 percent were newly added. We found that manuscripts in the natural and medical sciences undergo more extensive reframing of the literature while changes in engineering mostly focused on methodological details. Our qualitative analysis suggests that peer review increases the methodological soundness of scientific claims, improves the communication of findings, and ensures appropriate credit for previous research.

description: The study analyzed a conversation among a group of teachers responsible for teaching the concepts of mean, median, and mode. After reading an article describing some specific student difficulties in learning the concepts, teachers were asked to discuss how the teaching of the concepts could be improved. Several claims pertinent to improving teaching practice were offered. Claims focused on the appropriate age at which to introduce statistical concepts, the influence of the state-prescribed curriculum on teaching practice, content-specific teaching strategies, and content-independent teaching strategies. Teachers’ claims were discussed in terms of points of departure and agreement with existing empirical research.

description: In contrast to male rats, aggression in virgin female rats has been rarely studied. Here, we established a rat model of enhanced aggression in females using a combination of social isolation and aggression-training to specifically investigate the involvement of the oxytocin (OXT) and arginine vasopressin (AVP) systems within the lateral septum (LS). Using neuropharmacological, optogenetic, chemogenetic as well as microdialysis approaches, we revealed that enhanced OXT release within the ventral LS (vLS), combined with reduced AVP release within the dorsal LS (dLS), is required for aggression in female rats. Accordingly, increased activity of putative OXT receptor-positive neurons in the vLS, and decreased activity of putative AVP receptor-positive neurons in the dLS, are likely to underly aggression in female rats. Finally, in vitro activation of OXT receptors in the vLS increased tonic GABAergic inhibition of dLS neurons. Overall, our data suggest a model showing that septal release of OXT and AVP differentially affects aggression in females by modulating the inhibitory tone within LS sub-networks.

description: Luminous Red Novae (LRNe) are astrophysical transients associated with the partial ejection of a binary system's common envelope (CE) shortly before its merger. Here we present the results of our photometric and spectroscopic follow-up campaign of AT2018bwo (DLT18x), a LRN discovered in NGC45, and investigate its progenitor system using binary stellar-evolution models. The transient reached a peak magnitude of $M_r=-10.97\pm0.11$ and maintained this brightness during its optical plateau of $t_p = 41\pm5$days. During this phase, it showed a rather stable photospheric temperature of ~3300K and a luminosity of ~$10^{40}$erg/s. The photosphere of AT2018bwo at early times appeared larger and cooler than other similar LRNe, likely due to an extended mass-loss episode before the merger. Towards the end of the plateau, optical spectra showed a reddened continuum with strong molecular absorption bands. The reprocessed emission by the cooling dust was also detected in the mid-infrared bands ~1.5 years after the outburst. Archival Spitzer and Hubble Space Telescope data taken 10-14 years before the transient event suggest a progenitor star with $T_{prog}\sim 6500$K, $R_{prog}\sim 100R_{\odot}$ and $L_{prog}\sim 2\times10^4L_{\odot}$, and an upper limit for optically thin warm (1000 K) dust mass of $M_d<10^{-6}M_{\odot}$. Using stellar binary-evolution models, we determined the properties of binary systems consistent with the progenitor parameter space. For AT2018bwo, we infer a primary mass of 12-16 $M_{\odot}$, which is 9-45% larger than the ~11$M_{\odot}$ obtained using single-star evolution models. The system, consistent with a yellow-supergiant primary, was likely in a stable mass-transfer regime with -2.4

description: We study a small quantum system (e.g. a simplified model for an atom or molecule) interacting with two bosonic or fermionic reservoirs (say, photon or phonon fields). We show that the combined system has a family of stationary states, parametrized by two numbers $T_1$, $T_2$ (``reservoir temperatures''). If $T_1\neq T_2$, then these states are non-equilibrium, stationary states (NESS). In the latter case we show that they have nonvanishing heat fluxes and positive entropy production. Furthermore, we show that these states are dynamically asymptotically stable. The latter means that the evolution with an initial condition, normal with respect to any state where the reservoirs are in equilibria at temperatures $T_1$ and $T_2$, converges to the corresponding NESS. Our results are valid for the temperatures satisfying the bound $\min(T_1, T_2) > g^{2+α}$, where $g$ is the coupling constant and $0< α<1$ is a power related to the infra-red behaviour of the coupling functions.

description: Emotions at work have long been identified as critical signals of work motivations, status, and attitudes, and as predictors of various work-related outcomes. When more and more employees work remotely, these emotional signals of workers become harder to observe through daily, face-to-face communications. The use of online platforms to communicate and collaborate at work provides an alternative channel to monitor the emotions of workers. This paper studies how emojis, as non-verbal cues in online communications, can be used for such purposes and how the emotional signals in emoji usage can be used to predict future behavior of workers. In particular, we present how the developers on GitHub use emojis in their work-related activities. We show that developers have diverse patterns of emoji usage, which can be related to their working status including activity levels, types of work, types of communications, time management, and other behavioral patterns. Developers who use emojis in their posts are significantly less likely to dropout from the online work platform. Surprisingly, solely using emoji usage as features, standard machine learning models can predict future dropouts of developers at a satisfactory accuracy. Features related to the general use and the emotions of emojis appear to be important factors, while they do not rule out paths through other purposes of emoji use.

description: The nature of the U.S. farm sector and the character of nonmetro America are changing. Today's typical farm is highly dependent on other agribusiness firms including input industries (chemicals, fuels, equipment, and farm machinery) for basic production needs and on an increasingly centralized food manufacturing system which responds to increased consumer demands for more processed farm goods. Wholesale and retail trade activities, often considered part of the food and fiber system, are more closely linked to final demand and changing consumer preferences. This report describes the modern food and fiber complex and government commodity programs and how they affect nonmetro economies.

description: 4u 0115+63 is one of the most active and best studied Be/X-ray transients. Previous studies of 4u0115+63 have led to the suggestion that it undergoes relatively fast quasi-cyclic activity. However, due to the lack of good coverage of the observations, the variability time scales are uncertain. Our objective is to investigate the long-term behaviour of 4u 0115+63 to confirm its quasi-cyclic nature and to explain its correlated optical/IR and X-ray variability. We have performed optical/IR photometric observations and optical spectroscopic observations of 4u 0115+63 over the last decade with unprecedented coverage. We have focused on the Halpha line variability and the long-term changes of the photometric magnitudes and colours and investigated these changes in correlation with the X-ray activity of the source. results The optical and infrared emission is characterised by cyclic changes with a period of ~ 5 years. This long-term variability is attributed to the state of the circumstellar disc around the Be star companion. Each cycle involves a low state when the disc is very weak or absent and the associated low amplitude variability is orbitally modulated and a high state when a perturbed disc precesses, giving rise to fast and large amplitude photometric changes. X-ray outbursts in 4u 0115+63 come in pairs, i.e., two in every cycle. However, sometimes the second outburst is missing. Our results can be explained within the framework of the decretion disc model. The neutron star acts as the perturbing body, truncating and distorting the disc. The first outburst would occur before the disc is strongly perturbed. The second outburst leads to the dispersal of the disc and marks the end of the perturbed phase.

Top-down acetylcholine signaling via olfactory bulb vasopressin cells contributes to social discrimination in rats

Publisher: name: Universität Regensburg

description: Social discrimination in rats requires activation of the intrinsic bulbar vasopressin system, but it is unclear how this system comes into operation, as olfactory nerve stimulation primarily inhibits bulbar vasopressin cells (VPCs). Here we show that stimulation with a conspecific can activate bulbar VPCs, indicating that VPC activation depends on more than olfactory cues during social interaction. A series of in vitro electrophysiology, pharmacology and immunohistochemistry experiments implies that acetylcholine, probably originating from centrifugal projections, can enable olfactory nerve-evoked action potentials in VPCs. Finally, cholinergic activation of the vasopressin system contributes to vasopressin-dependent social discrimination, since recognition of a known rat was blocked by bulbar infusion of the muscarinic acetylcholine receptor antagonist atropine and rescued by additional bulbar application of vasopressin. Thus, our results implicate that top-down cholinergic modulation of bulbar VPC activity is involved in social discrimination in rats.

description: Photonics is a promising platform for demonstrating a quantum computational advantage (QCA) by outperforming the most powerful classical supercomputers on a well-defined computational task. Despite this promise, existing proposals and demonstrations face challenges. Experimentally, current implementations of Gaussian boson sampling (GBS) lack programmability or have prohibitive loss rates. Theoretically, there is a comparative lack of rigorous evidence for the classical hardness of GBS. In this work, we make progress in improving both the theoretical evidence and experimental prospects. We provide evidence for the hardness of GBS, comparable to the strongest theoretical proposals for QCA. We also propose a new QCA architecture we call high-dimensional GBS, which is programmable and can be implemented with low loss using few optical components. We show that particular algorithms for simulating GBS are outperformed by high-dimensional GBS experiments at modest system sizes. This work thus opens the path to demonstrating QCA with programmable photonic processors.

description: Aims. We present a systematic theoretical study on 40 polycyclic aromatic hydrocarbons dications (PAHs++) containing up to 66 carbon atoms. Methods. We performed our calculations using well established quantum-chemical techniques in the framework of the density functional theory (DFT) to obtain the electronic ground-state properties, and of the time-dependent DFT (TD-DFT) to evaluate the excited\textendash state properties. Results. For each PAH++ considered we computed the absolute visible-UV photo-absorption cross-section up to about 30 eV. We also evaluated their vibrational properties and compared them to those of the corresponding neutral and singly-ionised species. We estimated the adiabatic and vertical second ionisation energy DeltaI through total energy differences. Conclusions. The DeltaI values obtained fall in the energy range 8-13 eV, confirming that PAHs could reach the doubly-ionised state in HI regions. The total integrated IR absorption cross-sections show a marked increase upon ionization, being on the average about two and five times larger for PAHs++ than for PAHs+ and PAHs, respectively. The visible-UV photo-absorption cross-sections for the 0, +1 and +2 charge-states show comparable features but PAHs++ are found to absorb slightly less than their parent neutrals and singly ionized species between ~7 and ~12 eV. Combining these pieces of information we found that PAHs++ should actually be more stable against photodissociation than PAHs and PAHs+,_if_ dissociation tresholds are nearly unchanged by ionization.

description: Many topology-dependent transmission schedulingalgorithms have been proposed to minimize the time-divisionmultiple-access frame length in multihop packet radio networks (MPRNs), in which changes of the topology inevitably require recomputation of the schedules. The need for constant adaptation of schedules-to-mobile topology entails significant problems, especially in the highly dynamic mobile environments. Hence, topology-transparent scheduling algorithms have been proposed, which utilize Galois field theory and Latin squares theory. In thispaper, we discuss the topology-transparent broadcast scheduling design for MPRNs. For single-channel networks, we propose the modified Galois field design (MGD) and the Latin square design (LSD) for topology-transparent broadcast scheduling. The MGD obtains much smaller minimum frame length (MFL) than the existing scheme while the LSD can even achieve possible performance gain when compared with the MGD, under certain conditions. Moreover, the inner relationship between schedulingdesigns based on different theories is revealed and proved, which provides valuable insight. For the topology-transparent broadcast scheduling in multichannel networks, in which little research has been done, the proposed multichannel Galois field design (MCGD) can reduce the MFL approximately M times, as compared with the MGD when M channels are available. Numerical results show that the proposed algorithms outperform existing algorithms inachieving a smaller MFL.

description: Ribosome profiling (ribo-seq) is a technique that uses high-throughput sequencing technology to reveal the exact locations and densities of translating ribosomes at the transcriptome level. However experimentalists who generate ribo-seq data often have to rely on bioinformaticians to process and analyse their data. We have developed RiboGalaxy (http://ribogalaxy.ucc.ie/), a freely available Galaxy-based web server specifically tailored for pre-processing, aligning and analysing ribo-seq data with the visualization functionality provided by GWIPS-viz (http://gwips.ucc.ie).

description: The lack of time-reversal symmetry and Weyl fermions give exotic transport properties to Co-based Heusler alloys. In the present study, we have investigated the role of chemical disorder on the variation of Weyl points in Co\textsubscript{2}Ti\textsubscript{1-x}V\textsubscript{x}Sn magnetic Weyl semimetal candidate. We employ the first principle approach to track the evolution of the nodal lines responsible for the appearance of Weyl node in Co$_2$TiSn as a function of V substitution in place of Ti. By increasing the V concentration in place of Ti, the nodal line moves toward Fermi level and remains at Fermi level around the middle composition. Further increase of the V content, leads shifting of nodal line away from Fermi level. Density of state calculation shows half-metallic behavior for the entire range of composition. The magnetic moment on each Co atom as a function of V concentration increases linearly up to x=0.4, and after that, it starts decreasing. We also investigated the evolution of the Weyl nodes and Fermi arcs with chemical doping. The first-principles calculations reveal that via replacing almost half of the Ti with V, the intrinsic anomalous Hall conductivity increased twice as compared to the undoped composition. Our results indicate that the composition close to the 50\% V doped Co$_2$TiSn, will be an ideal composition for the experimental investigation of Weyl physics.

description: Precise measurements of radial (RV) and rotational (vsini) velocities of stars are essential for studying stellar kinematics (space velocities and dispersions), binary orbits (mass measurements and formation), and rotational dynamics (angular momentum evolution). The high-resolution spectroscopic observations necessary to make these measurements are challenging for the intrinsically faint and low-temperature ultracool dwarfs, stellar and sub-stellar objects with masses below 0.1 MSun. Previous local UCD kinematic studies indicated conflicting L dwarf kinematic ages, with little constraints on the T dwarf kinematic due to the small sample size. We present a radial and rotational velocity survey of 37 nearby (d ≤ 20 pc) T dwarfs based on forward-modeling analysis of nearly twenty years of high-resolution spectra obtained with Keck/NIRSPEC. We present the distributions of our RV and vsini measurements, and statistically analyze kinematic ages of the local ultracool dwarf population-based on RV and astrometric measurements of 173 late-M, L, and T dwarfs within 20 pc, and show that the L dwarfs as a population are significantly more dispersed and hence older than expected from population simulations. However, the local L dwarf sample has a higher fraction of thick disk sources, and removing them brings the L dwarf age into alignment, resolving a decade-old mystery. A kinematic dispersion break is found around the L4–L6 subtypes, which likely reflects the terminus of the stellar Main Sequence.

description: We analyse the relationship between the full additivity of the entanglement cost and its full monotonicity under local operations and classical communication. We show that the two properties are equivalent for the entanglement cost. The proof works for the regularization of any convex, subadditive, and asymptotically continuous entanglement monotone, and hence also applies to the asymptotic relative entropy of entanglement.

description: In denervation it was generally believed that no effective treatment was available for muscle that has undergone severe atrophy resulting from a chronic denervation injury. Under the Gutmann’s view of the trophic influence of nerves on muscle, the effect of a mimicking approach, electrical stimulation, played an important role, but over the years the value of electrically stimulating the denervated muscle has been disputed because of the difficulties to obtain strong contraction by electrical stimulation and of its possible unfavorably effects on any remaining potential for reinnervation. In the last 15 years, we studied the possibility to effectively train permanently denervated human muscles by means of Functional Electrical Stimulation (FES). The results of the EU Project RISE show a new perspective in stimulating muscle fibers in the absence of nerves and after prolonged denervation, enabling: i) restoration of muscle fiber ultrastructure; ii) recovery of conduction velocity of the excitation-contraction apparatus up to a level that allows tetanic contractility; and thus iii) astonishingly recovery of fiber size, muscle mass and FES-induced force production.

Our training strategy is based on two combined stimulation programs. Within continuous clinical assessments, the stimulation parameters and training protocols should be progressively modified according to the patient’s time span of denervation, the current condition of muscle and function. At the beginning of the treatment, biphasic stimulation impulses of very long-duration (120-150 ms, 60-75 ms per phase) at high intensity should be applied to improve membrane excitability and muscle structure. The next period of the routine daily training consists of combined stimulation patterns one eliciting single twitches (impulse duration of 120 ms) and the other tetanic contractions (2-3 s bursts with an impulse duration of 36-50 ms and impulse pause of 10 ms). After tetanic contractility is achieved and the subject is able to provide full extension of the leg during stimulation of the quadriceps muscles, the ankle should be progressively loaded following the training theory for healthy people. Finally, few patients who have achieved a good muscle and functional condition can be able to stand and perform step-in-place and walking exercise with stimulation to train the cardiovascular system, upper body, sense of balance and thigh muscles.

description: Although the notion of the parallelism in multidimensionalapplications has existed for a long time, it is so farunknown what the bound (if any) of inter-iteration parallelism in multirate multidimensional digital signal processing (DSP) algorithms is, and whether the maximum inter-iteration parallelism can be achieved for arbitrary multirate data flow algorithms. This paper explores the bound of inter-iteration parallelism within rate-balanced multirate multidimensional DSP algorithms and proves that this parallelism can always be achieved in hardware system given the availability of a large number of processors and the interconnections between them.
