description: If dark matter self-annihilates into neutrinos or a second component of ("boosted") dark matter that is nucleophilic, the annihilation products may be detected with high rates via coherent nuclear scattering. A future multi-ten-tonne liquid xenon detector such as DARWIN, and a multi-hundred-tonne liquid argon detector, ARGO, would be sensitive to the flux of these particles in complementary ranges of $10-1000$ MeV dark matter masses. We derive these sensitivities after accounting for atmospheric and diffuse supernova neutrino backgrounds, and realistic nuclear recoil acceptances. We find that their constraints on the dark neutrino flux may surpass neutrino detectors such as Super-Kamiokande, and that they would extensively probe parametric regions that explain the missing satellites problem in neutrino portal models. The XENON1T and Borexino experiments currently restrict the effective baryonic coupling of thermal boosted dark matter to $\lesssim 10-100 \ \times$ the weak interaction, but DARWIN and ARGO would probe down to couplings 10 times smaller. Detection of boosted dark matter with baryonic couplings $\sim 10^{-3}-10^{-2} \ \times$ the weak coupling could indicate that the dark matter density profile in the centers of galactic halos become cored, rather than cuspy, through annihilations. This work demonstrates that, alongside liquid xenon, liquid argon direct detection technology would emerge a major player in dark matter searches within and beyond the WIMP paradigm.

description: Abstract Background Peer support is an essential part of recovery-oriented care worldwide. Contextual factors have an impact on the implementation of peer support work. However, research has paid little attention to similarities and differences of implementation factors in settings varying by income-level and cultural values. The aim of this study is to assess the factors influencing the implementation of a peer support intervention across study sites in low-, middle- and high-income countries in line with the Consolidation Framework for Implementation Research (CFIR). Method 6 focus groups with a total of 54 key informants with relevant contextual (organisational) knowledge regarding implementation facilitators and barriers were conducted at six study sites Ulm and Hamburg (Germany), Butabika (Uganda), Dar es Salaam (Tanzania), Be’er Sheva (Israel), and Pune (India) before and 1.5 years after the start of UPSIDES peer support. Transcripts were analysed using qualitative content analysis. Results Across study sites key informants reported benefits of peer support for service users and peer support workers as implementation facilitators. At study sites with lower resources, reduced workload for mental health workers and improved access to mental health services through peer support were perceived as implementation facilitators (CFIR Domain 1: Intervention characteristics). The degree of engagement of mental health workers (CFIR Domain 3: Inner Setting/Domain 4: Individuals involved) varied across study sites and was seen either as a barrier (low engagement) or a facilitator (high engagement). Across study sites, adequate training of peer support workers (CFIR Domain 5: Implementation process) was seen as animplementation facilitator, while COVID-19 as well as low resource availability were reported as implementation barriers (CFIR Domain 2: Outer setting). Conclusions This study highlights the importance of considering contextual factors when implementing peer support, including previous experience and perceived benefits. Particular attention should be given to organisational benefits such as workload reduction and the allocation of sufficient resources as key drivers in LMICs. In HICs, the potential of organisational benefits for successful implementation should be further investigated and promoted.

description: The stochastic extinction and stability in the mean of a family of SEIRS malaria models with a general nonlinear incidence rate is presented. The dynamics is driven by independent white noise processes from the disease transmission and natural death rates. The basic reproduction number $R^{*}_{0}$, the expected survival probability of the plasmodium $E(e^{-(μ_{v}T_{1}+μT_{2})})$, and other threshold values are calculated. A sample Lyapunov exponential analysis for the system is utilized to obtain extinction results. Moreover, the rate of extinction of malaria is estimated, and innovative local Martingale and Lyapunov functional techniques are applied to establish the strong persistence, and asymptotic stability in the mean of the malaria-free steady population. %The extinction of malaria depends on $R^{*}_{0}$, and $E(e^{-(μ_{v}T_{1}+μT_{2})})$. Moreover, for either $R^{*}_{0}<1$, or $E(e^{-(μ_{v}T_{1}+μT_{2})})

description: By means of magneto-optical Kerr effect we observe for the first time antiferromagnetic coupling between ferromagnetic layers across an amorphous metallic spacer layer. Biquadratic coupling occurs at the transition from a ferromagnetically to an antiferromagnetically coupled region. Scanning tunneling microscopy images of all involved layers are used to extract thickness fluctuations and to verify the amorphous state of the spacer. The observed antiferromagnetic coupling behavior is explained by RKKY interaction taking into account the amorphous structure of the spacer material.

description: Spatio temporal data are more ubiquitous and richer than even before and the availability of such data poses great challenges in data analytics. Ecological facilitation, the positive effect of density of individuals on the individual's survival across a stress gradient, is a complex phenomenon. A large number of tree individuals coupled with soil moisture, temperature, and water stress data across a long temporal period were followed. Data driven analysis in the absence of hypothesis was performed. Information theoretic analysis of multiple statistical models was employed in order to quantify the best data-driven index of vegetation density and spatial scale of interactions. Sequentially, tree survival was quantified as a function of the size of the individual, vegetation density, and time at the optimal spatial interaction scale. Land surface temperature and soil moisture were also statistically explained by tree size, density, and time. Results indicated that in space both facilitation and competition coexist in the same ecosystem and the sign and magnitude of this depend on the spatial scale. Overall, within the optimal data driven spatial scale, tree survival was best explained by the interaction between density and year, sifting overall from facilitation to competition through time. However, small sized trees were always facilitated by increased densities, while large sized trees had either negative or no density effects. Tree size was more important predictor than density in survival and this has implications for nature based solutions: maintaining large tree individuals or planting species that can become large-sized can safeguard against tree less areas by promoting survival at long time periods through harsh environmental conditions. Large trees had also a significant effect in moderating land surface temperature.

description: The statistics of the energy eigenvalues at the metal-insulator-transition of a two-dimensional disordered system with spin-orbit interaction is investigated numerically. The critical exponent $ν$ is obtained from the finite-size scaling of the number $J_0$ which is related to the probability $Q_{n}(s)$ of having $n$ energy levels within an interval of width $s$. In contrast to previous estimates, we find $ν=2.32\pm 0.14$ close to the value of the two-dimensional quantum Hall system.

description: We investigate the thermal cosmology and terrestrial and astrophysical phenomenology of a sub-GeV hadrophilic dark sector. The specific construction explored in this work features a Dirac fermion dark matter candidate interacting with a light scalar mediator that dominantly couples to the up-quark. The correct freeze-out relic abundance may be achieved via dark matter annihilation directly to hadrons or through secluded annihilation to scalar mediators. A rich and distinctive phenomenology is present in this scenario, with probes arising from precision meson decays, proton beam dump experiments, colliders, direct detection experiments, supernovae, and nucleosynthesis. In the future, experiments such as NA62, REDTOP, SHiP, SBND, and NEWS-G will be able to explore a significant portion of the cosmologically motivated parameter space.

description: This paper presents a non-trivial reconstruction of a previous joint topic-sentiment-preference review model TSPRA with stick-breaking representation under the framework of variational inference (VI) and stochastic variational inference (SVI). TSPRA is a Gibbs Sampling based model that solves topics, word sentiments and user preferences altogether and has been shown to achieve good performance, but for large data set it can only learn from a relatively small sample. We develop the variational models vTSPRA and svTSPRA to improve the time use, and our new approach is capable of processing millions of reviews. We rebuild the generative process, improve the rating regression, solve and present the coordinate-ascent updates of variational parameters, and show the time complexity of each iteration is theoretically linear to the corpus size, and the experiments on Amazon data sets show it converges faster than TSPRA and attains better results given the same amount of time. In addition, we tune svTSPRA into an online algorithm ovTSPRA that can monitor oscillations of sentiment and preference overtime. Some interesting fluctuations are captured and possible explanations are provided. The results give strong visual evidence that user preference is better treated as an independent factor from sentiment.
Expanding FTMap for the fragment-based identification of pharmacophore regions in ligand binding sites
Creators: name: Khan, Omeir
Publisher: name: Conscience
Year: 2024

description: Abstract:In fragment-based drug discovery, the binding mode of a fragment bound to a hot spot is expected to be conserved as it is optimized into a larger ligand.1,2 Therefore, predicting the locations of intermolecular interactions that are conserved in fragment-lead pairs is of great importance in the context of pharmacophore generation. To aid in the identification of pharmacophore regions in ligand binding sites we have developed E-FTMap, a computational solvent mapping algorithm which exhaustively maps binding sites with dozens of small organic probes, and identifies important interaction sites as atomic consensus sites (ACSs) where similar chemical groups bind. We validate E-FTMap against a set of 109 experimentally derived structures of fragment-lead pairs, finding highly ranked pharmacophore features that overlap with corresponding atoms in both fragment and lead compounds. Additionally, we compare mapping results to pharmacophores derived from ensembles of bound ligands, revealing that E-FTMap results tend to sample highly conserved protein-ligand interactions. Furthermore, we explore an application of E-FTMap in the context of virtual ligand screening by using mapping results to score and rank ligands on the basis of their binding affinity.

The results are obtained by introducing a two-dimensional integral representation for the partition function decoupling both the hard-core interaction and the attractive one. The next-to-leading terms for each of the mentioned quantities is explicitly derived as well as the value of their sign that is related to their monotonic convergence in the thermodynamic limit.

description: Abstract The present study investigated whether life engagement and happiness can be predicted from gaming motives and primary emotional traits. Two machine learning algorithms (random forest model and one-dimensional convolutional neural network) were applied using a dataset from before the COVID-19 pandemic as the training dataset. The algorithms derived were then applied to test if they would be useful in predicting life engagement and happiness from gaming motives and primary emotional systems on a dataset collected during the pandemic. The best prediction values were observed for happiness with ρ = 0.758 with explained variance of R 2  = 0.575 when applying the best performing algorithm derived from the pre-COVID dataset to the COVID dataset. Hence, this shows that the derived algorithm based on the pre-pandemic data set, successfully predicted happiness (and life engagement) from the same set of variables during the pandemic. Overall, this study shows the feasibility of applying machine learning algorithms to predict life engagement and happiness from gaming motives and primary emotional systems. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

description: A hydro system of the level of reservoir metaphorically can be well thought as a living organism of two substances, which develop over time. The two elements concern both water supply to meet the demand and maintain good water quality in the reservoir. In this research the two conflicting substances, have to deal two components satisfied simultaneously which must find a balance between them. The analysis of those two elements based on methods and implemented on multi-criteria optimization using evolutionary algorithms. The search of the optimal solutions that satisfies both elements of the reservoir, and reconciles the conflict is the final product of this work. A target management of the reservoir which is realized on the basis of rules and restrictions, rejecting the ideology of brutal consumerism, but at the same time examining a qualitative dimension of the subject, constitutes the aim of the present research.
Towards classification of Fracton phases: the multipole algebra

description: We present an effective field theory approach to the Fracton phases. The approach is based the notion of a multipole algebra. It is an extension of space(-time) symmetries of a charge-conserving matter that includes global symmetries responsible for the conservation of various components of the multipole moments of the charge density. We explain how to construct field theories invariant under the action of the algebra. These field theories generally break rotational invariance and exhibit anisotropic scaling. We further explain how to partially gauge the multipole algebra. Such gauging makes the symmetries responsible for the conservation of multipole moments local, while keeping rotation and translations symmetries global. It is shown that upon such gauging one finds the symmetric tensor gauge theories, as well as the generalized gauge theories discussed recently in the literature. The outcome of the gauging procedure depends on the choice of the multipole algebra. In particular, we show how to construct an effective theory for the $U(1)$ version of the Haah code based on the principles of symmetry and provide a two dimensional example with operators supported on a Sierpinski triangle. We show that upon condensation of charged excitations Fracton phases of both types as well as various SPTs emerge. Finally, the relation between the present approach and the formalism based on polynomials over finite fields is discussed.

Year: 2018
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We study chiral algebras in the $\bar{Q}$-cohomology of two dimensional SYK models with extended supersymmetry. In a special limit discovered in arXiv:1805.09325, we are able to construct explicitly a "vertical" single-particle higher-spin algebra that is bilinear in the fundamental fields. This algebra can be regarded as the counterpart, when going away from criticality, of the infrared emergent higher-spin symmetry of the $\mathcal{N}=(0,2)$ SYK model. Moreover, a second "horizontal" single-particle higher-spin algebra appears in this limit. Together with the vertical algebra they generate a stringy algebra with a "higher spin square" structure that is believed to appear in the tensionless limit of string theory. On the other hand, we do not find single-particle higher-spin algebra away from the special limit, which is consistent with the result in arXiv:1805.09325. Our analysis is carried out for each individual realization of the random couplings and for finite $N$ (and $M$), which in particular indicates that the conclusion in arXiv:1805.09325 is robust to $1/N$ corrections.

description: Traumatic brain injury (TBI) is a leading cause of mortality and disability worldwide. Acute neuroinflammation is a prominent reaction after TBI and is mostly initiated by brain-resident glial cells such as microglia, NG2-glia and astrocytes. The magnitude of this reaction paves the way for long-lasting consequences such as chronic neurological pathologies, for which therapeutic options remain limited. The neuroinflammatory response to TBI is mostly studied with craniotomy-based animal models that are very robust but also rather artificial. Here, we aimed to analyze the reaction of glial cells in a highly translational but variable closed head injury (CHI) model and were able to correlate the severity of the trauma to the degree of glial response. Furthermore, we could show that the different glial cell types react in a temporally and spatially orchestrated manner in terms of morphological changes, proliferation, and cell numbers in the first 15 days after the lesion. Interestingly, NG2-glia, the only proliferating cells in the healthy brain parenchyma, divided at a rate that was correlated with the size of the injury. Our findings describe the previously uncharacterized posttraumatic response of the major brain glial cell types in CHI in order to gain a detailed understanding of the course of neuroinflammatory events; such knowledge may open novel avenues for future therapeutic approaches in TBI.
A recharge-discharge water budget and evaluation of water budgets for the Edwards Aquifer associated with Barton Springs
Creators: name: Slade, Raymond Maurice
Publisher: name: Texas Water Journal
Year: 2017

description: The Barton Springs segment of the Edwards Aquifer represents a small, relatively independent part of the aquifer. Data for the sources of recharge and especially for discharge from the aquifer are well documented. Based on a 6-year water budget of surface recharge and surface discharge, the volumes match within 5%, which is within the potential error limits of the recharge and discharge values. Recharge volumes include increased runoff due to urbanization in the recharge area. A previous water budget based on an earlier period also displayed a balance between recharge and discharge volumes. Both budgets are based on slightly “wetter” than long-term mean recharge and discharge conditions, thus subsurface recharge from south of the aquifer segment, which is documented to occur during dry conditions, was an insignificant source of recharge during the budget periods. The recharge volumes are based on data from streamflow gaging stations operated by the U.S. Geological Survey. However, one of the stations (Bear Creek near Brodie Lane) was discontinued in 2010; this station is needed to calculate recharge volumes on Bear Creek and Little Bear Creek. Because of the discontinuance of the station, any calculations of recharge volumes after 2010 would contain substantial potential error.

description: In this paper, we shall prove that a harmonic map from $\mathbb{C}^{n}$ ($n\geq2$) to any Kahler manifold must be holomorphic under an assumption of energy density. It can be considered as a complex analogue of the Liouville type theorem for harmonic maps obtained by Sealey.

description: Aims: MASCARA and bRing are photometric surveys designed to detect variability caused by exoplanets in stars with $m_V < 8.4$. Such variability signals are typically small and require an accurate calibration algorithm, tailored to the survey, in order to be detected. This paper presents the methods developed to calibrate the raw photometry of the MASCARA and bRing stations and characterizes the performance of the methods and instruments. Methods: For the primary calibration a modified version of the coarse decorrelation algorithm is used, which corrects for the extinction due to the earth's atmosphere, the camera transmission, and intrapixel variations. Residual trends are removed from the light curves of individual stars using empirical secondary calibration methods. In order to optimize these methods, as well as characterize the performance of the instruments, transit signals were injected in the data. Results: After optimal calibration an RMS scatter of 10 mmag at $m_V \sim 7.5$ is achieved in the light curves. By injecting transit signals with periods between one and five days in the MASCARA data obtained by the La Palma station over the course of one year, we demonstrate that MASCARA La Palma is able to recover 84.0, 60.5 and 20.7% of signals with depths of 2, 1 and 0.5% respectively, with a strong dependency on the observed declination, recovering 65.4% of all transit signals at $δ> 0^\circ$ versus 35.8% at $δ< 0^\circ$. Using the full three years of data obtained by MASCARA La Palma to date, similar recovery rates are extended to periods up to ten days. We derive a preliminary occurrence rate for hot Jupiters around A-stars of ${>} 0.4 \%$, knowing that many hot Jupiters are still overlooked. In the era of TESS, MASCARA and bRing will provide an interesting synergy for finding long-period (${>} 13.5$ days) transiting gas-giant planets around the brightest stars.

description: Nicotinic receptors are ligand-gated ion channels, involved in the generation of action potential in post synaptic membrane and motor endplate. The α7 Nicotinic Acetylcholine Receptor (nAChR) is a class of nicotinic receptor involved in cognition. It is distributed in hippocampus, thalamus, sensory and information processing regions of the brain. The receptor is implicated in various diseases, including Alzheimer’s disease, Parkinsonism, Schizophrenia, Autism, Rett syndrome etc. Therefore, targeting the modulation of the receptor would be advantageous. Positive allosteric modulators (PAMs) potentiate the response i.e. peak current of the receptor. Type I allosteric modulator, Anvylic-3288 (AVL-3288), increases peak current without altering the response of α7-nAChR upon acetylcholine binding. In present study, in silico approach was used to identify the plausible binding model of AVL-3288 involved in modulation. Docking study displayed that a1 binding modes had better binding energies than the t1 and v1 modes. The MD (Molecular Dynamics) simulation produced stable complex for a1 pose, binding to agonist subpocket, with α7-nAChR having protein and ligand RMSD (Root Mean Square Deviation) in the acceptable limits, and comparable to MM/PBSA (Molecular Mechanics Poisson-Boltzmann Surface Area) results.

description: We investigate the instability of the saturated ferromagnetic ground state (Nagaoka state) in the Hubbard model on various lattices in dimensions d=2 and d=3. A variational resolvent approach is developed for the Nagaoka instability both for U = infinity and for U < infinity which can easily be evaluated in the thermodynamic limit on all common lattices. Our results significantly improve former variational bounds for a possible Nagaoka regime in the ground state phase diagram of the Hubbard model. We show that a pronounced particle-hole asymmetry in the density of states and a diverging density of states at the lower band edge are the most important features in order to stabilize Nagaoka ferromagnetism, particularly in the low density limit.

description: Ο σκοπός της παρούσας εργασίας είναι η μελέτη του υγρού σπινθηριστή BC501A με την χρήση πηγών ακτίνων-γ. Η ιδιότητα διαχωρισμού μορφής παλμών από τον σπινθηριστή μελετήθηκε με την υλοποίηση δύο διαφορετικών ηλεκτρονικών διατάξεων με σκοπό να επιτευχθεί διαχωρισμός νετρονίων και ακτίνων-γ. Επιπλέον η μέθοδος σύμπτωσης ακτίνων-γ χρησιμοποιήθηκε για τον προσδιορισμό της ενεργειακής διακριτικής ικανότητας του ανιχνευτή και για τον προσδιορισμό του ύψους παλμού που αντιστοιχεί στο μέγιστο της ενέργειας των ηλεκτρονίων Compton για ενέργειες ηλεκτρονίων Compton από 164.3 έως 1118.2 keV. Ακόμα, η απόλυτη ολική ανιχνευτική απόδοση του ανιχνευτή για φωτόνια, για ενέργειες από 329.4 έως 1252.9 keV και για τις αποστάσεις των 0 και των 25 cm προσδιορίστηκε πειραματικά και με προσομοίωση με κώδικα MCNP. Για τους παραπάνω λόγους χρησιμοποιήθηκαν οι πηγές ακτίνων-γ 133Ba, 22Na, 137Cs, 54Mn και 60Co και η πηγή νετρονίων και ακτίνων-γ Am-Be.
description: The purpose of the present work is the study of the liquid scintillator BC501A using gamma-ray sources. The scintillator’s properties of pulse shape discrimination were examined by the development of two separate electronic systems in order to achieve neutron and gamma-ray discrimination. Besides, gamma-gamma coincidence technique was used to determine the detectors energy resolution and pulse height corresponding to the maximum energy of Compton electrons over the Compton electrons energy range of 164.3 to 1118.2 keV. Furthermore, the detectors absolute total efficiency to photons for the energy range of 329.4 to 1252.9 keV and for the distances of 0 and 25 cm, was determined experimentally and by simulation with the MCNP code. Towards these purposes gamma ray sources of 133Ba, 22Na, 137Cs, 54Mn and 60Co and neutron and gamma-ray source of Am-Be were used.

description: In this study, we present a complete experimental and theoretical investigation of the fundamental exciton Zeeman splitting in wurtzite InP nanowires. We determined the exciton gyromagnetic factor, $g_{exc}$, by magneto-photoluminescence spectroscopy using magnetic fields up to 29 T. We found that $g_{exc}$ is strongly anisotropic with values differing in excess of 50\% between the magnetic field oriented parallel and perpendicular to the nanowire long axis. Furthermore, for magnetic fields oriented along the nanowire axis, $g_{exc}$ is nearly three times larger than in bulk zincblende InP and it shows a marked sublinear dependence on the magnetic field, a common feature to other non-nitride III-V wurtzite nanowires but not properly understood. Remarkably, this nonlinearity originates from only one Zeeman branch characterized by a specific type of light polarization. All the experimental findings are modeled theoretically by a robust approach combining the $k \cdot p$ method with the envelope function approximation and including the electron-hole interaction. We revealed that the nonlinear features arise due to the coupling between Landau levels pertaining to the A (heavy-hole like) and B (light-hole like) valence bands of the wurtzite crystal structure. This general behavior is particularly relevant for the understanding of the spin properties of several wurtzite nanowires that host the set for the observation of topological phases potentially at the base of quantum computing platforms.
Bell inequalities with one bit of communication

description: We study Bell scenarios with binary outcomes supplemented by one bit of classical communication. We develop a method to find facet inequalities for such scenarios even when direct facet enumeration is not possible, or at least difficult. Using this method, we partially solve the scenario where Alice and Bob choose between three inputs, finding a total of 668 inequivalent facet inequalities (with respect to relabelings of inputs and outputs). We also show that some of these inequalities are constructed from the facet inequalities found in scenarios without communication, the well known Bell inequalities.
Non-Abelian Bosonization and Haldane's Conjecture

description: We study the long wavelength limit of a spin S Heisenberg antiferromagnetic chain. The fermionic Lagrangian obtained corresponds to a perturbed level 2S SU(2) Wess-Zumino-Witten model. This effective theory is then mapped into a compact U(1) boson interacting with Z_{2S} parafermions. The analysis of this effective theory allows us to show that when S is an integer there is a mass gap to all excitations, whereas this gap vanishes in the half-odd-integer spin case. This gives a field theory treatment of the so-called Haldane's conjecture for arbitrary values of the spin S.

description: We discuss production of Drell-Yan lepton pairs at hadron colliders in the framework of the parton Reggeization approach, which includes off-shell initial state effects in a gauge-invariant way. Other possible prescriptions to restore gauge-invariance of hard-scattering coefficient with off-shell initial-state partons are also investigated and significant differences for the resulting structure functions are found, especially for the $F_{UU}^{(\cos2ϕ)}$. We compare our numerical results for $q_T$-spectra of the lepton pair with experimental data, obtained by E-288 collaboration ($\sqrt{S}=19.4$ and 23.8 GeV) and find a good agreement. Also we perform predictions for the Drell-Yan structure functions at NICA $pp$-collider ($\sqrt{S}=24$ GeV).
