description: CYP2B6 is a polymorphic enzyme with a large number of variants which may lead to functional changes in enzyme activity and substrate selectivity. In this study, CYP2B6 and its three variants with and without psoralen, a mechanism-based inactivator, were investigated using molecular simulation method. The obtained docking orientation of psoralen was in agreement with previously identified site of metabolism. Stability analysis showed that the three variants displayed more flexibility than CYP2B6.1, and CYP2B6.34 was the most flexible one without psoralen binding. However, in the presence of psoralen, CYP2B6.34 became more rigidity. Tunnel analysis indicates that the bottleneck change of tunnels may be correlated to the increased or decreased activity of variants. Binding free energy analysis shows that van der Waals interaction dominates the binding of psoralen. CYP2B6.34 has the highest affinity to psoralen with lowest binding free energy. Ile114, Phe115 and heme contribute largely to the binding of psoralen with CYP2B6.6, while Phe206 and Leu363 play important roles for CYP2B6.1 and CYP2B6.4. These computational observations suggest that the increased activity of CYP2B6.4 and reduced activity of CYP2B6.6 may be due to changes in regional structures.
Topology Change in (2+1)-Dimensional Gravity

description: In (2+1)-dimensional general relativity, the path integral for a manifold $M$ can be expressed in terms of a topological invariant, the Ray-Singer torsion of a flat bundle over $M$. For some manifolds, this makes an explicit computation of transition amplitudes possible. In this paper, we evaluate the amplitude for a simple topology-changing process. We show that certain amplitudes for spatial topology change are nonvanishing---in fact, they can be infrared divergent---but that they are infinitely suppressed relative to similar topology-preserving amplitudes.

Extraction of nucleon momentum distributions from inclusive electron scattering on nuclei

Year: 1999

description: We address the problem of extracting single-nucleon momentum distributions $n(p)$ from inclusice scattering data. A model for these relates nuclear and nucleon structure functions (SF) through an intermediate SF $f^{PN}$ for a nucleus of point-particles. In addition to the asymptotic limit (AL) which depends on $n(p), f^{PN}$ contains, generally $q$-dependent Final State Interactions (FSI) parts. In the inverse problem one wishes to separate $q$-dependent FSI from the AL. In general it suffices to know the structure of the theory, but not numerical results. It appears, that in the $q$-range of the analyzed electron scattering data, FSI are only weakly $q$-dependent, making it virtually impossible to obtain parameters in a free fit of the parametrized components of $f$. Imposing a restriction, we obtain $n(p)$ for Fe and $^4$Fe.

Speeding Up the Bilateral Filter: A Joint Acceleration Way

description: Computational complexity of the brute-force implementation of the bilateral filter (BF) depends on its filter kernel size. To achieve the constant-time BF whose complexity is irrelevant to the kernel size, many techniques have been proposed, such as 2D box filtering, dimension promotion, and shiftability property. Although each of the above techniques suffers from accuracy and efficiency problems, previous algorithm designers were used to take only one of them to assemble fast implementations due to the hardness of combining them together. Hence, no joint exploitation of these techniques has been proposed to construct a new cutting edge implementation that solves these problems. Jointly employing five techniques: kernel truncation, best N -term approximation as well as previous 2D box filtering, dimension promotion, and shiftability property, we propose a unified framework to transform BF with arbitrary spatial and range kernels into a set of 3D box filters that can be computed in linear time. To the best of our knowledge, our algorithm is the first method that can integrate all these acceleration techniques and, therefore, can draw upon one another's strong point to overcome deficiencies. The strength of our method has been corroborated by several carefully designed experiments. In particular, the filtering accuracy is significantly improved without sacrificing the efficiency at running time.

description: In 1968, Ringel and Youngs confirmed the last open case of the Heawood Conjecture by determining the genus of every complete graph $K_n$. In this paper, we investigate the minimum genus embeddings of the complete $3$-uniform hypergraphs $K_n^3$. Embeddings of a hypergraph $H$ are defined as the embeddings of its associated Levi graph $L_H$ with vertex set $V(H)\sqcup E(H)$, in which $v\in V(H)$ and $e\in E(H)$ are adjacent if and only if $v$ and $e$ are incident in $H$. We determine both the orientable and the non-orientable genus of $K_n^3$ when $n$ is even. Moreover, it is shown that the number of non-isomorphic minimum genus embeddings of $K_n^3$ is at least $2^{\frac{1}{4}n^2\log n(1-o(1))}$. The construction in the proof may be of independent interest as a design-type problem.

description: This paper considers the scenario that multiple data owners wish to apply a machine learning method over the combined dataset of all owners to obtain the best possible learning output but do not want to share the local datasets owing to privacy concerns. We design systems for the scenario that the stochastic gradient descent (SGD) algorithm is used as the machine learning method because SGD (or its variants) is at the heart of recent deep learning techniques over neural networks. Our systems differ from existing systems in the following features: {\bf (1)} any activation function can be used, meaning that no privacy-preserving-friendly approximation is required; {\bf (2)} gradients computed by SGD are not shared but the weight parameters are shared instead; and {\bf (3)} robustness against colluding parties even in the extreme case that only one honest party exists. We prove that our systems, while privacy-preserving, achieve the same learning accuracy as SGD and hence retain the merit of deep learning with respect to accuracy. Finally, we conduct several experiments using benchmark datasets, and show that our systems outperform previous system in terms of learning accuracies.

Theoretical aspects of the CEBAF 89-009 experiment on inclusive scattering of 4.05 GeV electrons from nuclei

description: We compare recent CEBAF data on inclusive electron scattering on nuclei with predictions, based on a relation between structure functions (SF) of a nucleus, a nucleon and a nucleus of point-nucleons. The latter contains nuclear dynamics, e.g. binary collision contributions in addition to the asymptotic limit. The agreement with the data is good, except in low-intensity regions. Computed ternary collsion contributions appear too small for an explanation. We perform scaling analyses in Gurvitz's scaling variable and found that for $y_G\gtrless 0$, ratios of scaling functions for pairs of nuclei differ by less than 15-20% from 1. Scaling functions for $0$ are, for increasing $Q^2$, shown to approach a plateau from above. We observe only weak $Q^2$-dependence in FSI, which in the relevant kinematic region is ascribed to the diffractive nature of the NN amplitudes appearing in FSI. This renders it difficult to separate asymptotic from FSI parts and seriously hampers the extraction of $n(p)$ from scaling analyses in a model-independnent fashion.

description: A non-singular, static spherically symmetric solution to the nonsymmetric gravitational and electromagnetic theory field equations is derived, which depends on the four parameters m, l^2, Q and s, where m is the mass, Q is the electric charge, l^2 is the NGT charge of a body and s is a dimensionless constant. The electromagnetic field invariants are also singularity-free, so that it is possible to construct regular particle-like solutions in the theory. All the curvature invariants are finite, there are no null surfaces in the spacetime and there are no black holes. A new stable, superdense object (SDO) replaces black holes.

description: We explore the origin of the observed decline in [O/Fe] (and [Mg/Fe]) with Galactocentric distance for high-metallicity stars ([Fe/H] > -1.1), based on a sample of halo stars selected within the Apache Point Observatory Galactic Evolution Experiment (APOGEE) fourteenth data release (DR14). We also analyse the characteristics of the [$α$/Fe] distributions in the inner-halo regions inferred from two zoom-in Milky Way mass-sized galaxies that are taken as case studies. One of them qualitatively reproduces the observed trend to have higher fraction of $α$-rich star for decreasing galactocentric distance; the other exhibits the opposite trend. We find that stars with [Fe/H] > -1.1 located in the range [15 - 30] kpc are consistent with formation in two starbursts, with maxima separated by about ~ 1 Gyr. We explore the contributions of stellar populations with different origin to the [$α$/Fe] gradients detected in stars with [Fe/H] > -1.1. Our analysis reveals that the simulated halo that best matches the observed chemical trends is characterised by an accretion history involving low to intermediate-mass satellite galaxies with a short and intense burst of star formation, and contributions from a more massive satellite with dynamical masses about ~ 10$^{10}$M$_{\odot}$, distributing low-[$α$/Fe] stars at intermediate radius.

description: We study implications of a model, which links nuclear and nucleon structure functions. Computed Callen-Gross functions $κ^A(x,Q^2)= 2xF_1^A(x,Q^2)/F_2^A(x,Q^2)$ appear for finite $Q^2$ to be close to their asymptotic value 1. Using those $κ$, we compure $R$ ratios for $Q^2\ge 5 GeV^2$. We review approximate methods in use for the extraction of $R$ from inclusive scattering and ENC data. Further we calcuate ratios of the moments of $F_k$ and find these to describe the data, in particular their $Q^2$ dependence. The above observables, as well as inclusive cross sections, are sensitive tests for the underlying relation between nucleonic and nuclear structure functions. In view of the overall agreement, we speculate that the above relation effectively circumvents a QCD calculation.

description: Rare-earth nickelates exhibit a remarkable metal-insulator transition accompanied by a structural transition associated with a lattice `breathing' mode. Using model considerations and first-principles calculations, we present a theory of this phase transition, which reveals the key role of the coupling between the electronic and lattice instabilities. We show that the transition is driven by the proximity to an electronic disproportionation instability which couples to the breathing mode, thus cooperatively driving the system into the insulating state. This allows us to identify two key control parameters of the transition: the susceptibility to electronic disproportionation and the stiffness of the lattice mode. We show that our findings can be rationalized in terms of a Landau theory involving two coupled order parameters, with general implications for transition-metal oxides.

description: Libraries of stellar spectra find many uses in astrophysics, from photometric calibration to stellar population synthesis. We present low resolution spectra of 40 stars from 0.2 micrometers (ultraviolet) to 1.0 micrometers (near infrared) with excellent fluxing. The stars include normal O-type stars, helium-burning stars, and post-asymptotic giant branch (PAGB) stars. Spectra were obtained with the Space Telescope Imaging Spectrograph (STIS) installed in the Hubble Space Telescope (HST) using three low resolution gratings, G230LB, G430L, and G750L. Cosmic ray hits and fringing in the red were corrected. A correction for scattered light was applied, significant only for our coolest stars. Cross-correlation was used to bring the spectra to a common, final, zero velocity wavelength scale. Finally, synthetic stellar spectra were used to estimate line of sight dust extinction to each star, and a five-parameter dust extinction model was fit, or a one-parameter fit in the case of low extinction. These spectra dovetail with the similar Next Generation Stellar Library (NGSL) spectra, extending the NGSL's coverage of stellar parameters, and extending to helium burning stars and stars that do not fuse. The fitted dust extinction model showed considerable variation from star to star, indicating variations in dust properties for different lines of sight. Interstellar absorption lines are present in most stars, notably MgII.

description: Static solutions of the Einstein-Yang-Mills-Higgs system containing extreme black holes are studied. The field equations imply strong restrictions on boundary values of all fields at the horizon. If the Yang-Mills radial electric field $E$ is non-zero there, then all fields at the horizon take values in the centralizer of $E$. For the particular case of SU(3), there are two different kinds of centralizers: two-dimensional abelian (Cartan subalgebra) and four-dimensional (su(2)$\times$u(1)) ones. The two-dimensional centralizer admits only constant fields: even the geometry of the horizon is that of constant curvature. If the cosmological constant $Λ$ is negative, a two-surface of any genus is possible; for positive curvature, only spherically symmetrical horizons are allowed. For the four-dimensional centralizer, all spherically symmetrical horizons are explicitly given.

description: Protracted conflicts are common and complex, and differ from other types of disputes because of their ongoing escalation, non-negotiable issues, unsuccessful interventions, and passage of time. Prior research on this topic lacks good operationalizations of these features. This not only makes it difficult to compare research on how journalists and media portray such conflict but also challenging to analyze such phenomena. Hence, this study develops codes for features of protracted conflict and then applies those to the case of the news coverage (n = 148) of the 2008–2009 negotiations between the Screen Actors Guild of America and the Alliance of Motion Picture and Television Producers. Results demonstrate the applicability of these features to describe news coverage of a labor management conflict setting, illustrate how these features vary over time and show how features are interrelated, to reveal two underlying dimensions of the particular conflict (temporal context and resolution flexibility) and possibly protracted conflicts in general.

description: We describe algorithms that build on a new suite of tools (Melsted et al. 2019) for accurate and efficient pre-processing of single-cell RNA-seq. Utilizing more than two dozen datasets for benchmarking, we demonstrate our method is up to 50 times faster, and uses an order of magnitude less RAM than Cell Ranger, which is the current standard. Specifically, the speed and efficiency of our workflow makes Amazon Web Services cloud computing with our method 295x cheaper than Cell Ranger, 21x cheaper than STARSolo (Dobin et al. 2013), and 5x cheaper than Alevin (Srivastava et al. 2019). Novel algorithmic developments include a method for identifying reads that are unambiguously from nascent or mature mRNA, based on assignment of the molecules they are derived from. This leads to an efficient, low-memory method for RNA velocity (La Manno et al. 2018). We also demonstrate accurate pre-processing of inDrops data (Klein et al. 2015), and describe a novel algorithm for analysis of feature barcoding data such as CITE-Seq (Stoeckius et al. 2017) and ClickTag (Gehring et al. 2018).

A model that has probed its feasibility for inclusive quasi-elastic (e,e') processes is considered. Sensitivity to final state interactions between the outgoing proton and the residual nucleus is discussed by comparing the results obtained with phenomenological optical potentials and a continuum nuclear shell-model calculation. The contribution of the meson-exchange and isobar currents to the response functions is evaluated and compared to previous calculations, which differ notably from our results. These two-body contributions cannot solve the puzzle of the simultaneous description of the different responses experimentally separated. Copyright 1999 by The American Physical Society

description: The content of mercury in fish muscle tissue and its correlation with biotic and abiotic indicators of the aquatic ecosystem in the estuary area of the Red River (Vietnam) are discussed in the work. The study was carried out in the estuary area of the Red River for 6 years. Exceeding Vietnamese health standards for mercury in food products was observed in the freshwater catfish (Clarias batrachus), snakehead (Channa Striata), eastern tuna (Euthynnus affinis), red snapper (Lutjanus vitta) and eastern flyfish (Dactyloptena orientalis) (1,7; 1,2; 1,8; 1,3 and 1,1 times, respectively). The dependences of the mercury content in fish muscle tissue on their mass, food items and trophic position in the food chain are given. The leading role in the accumulation of mercury in the body of fish is played by the type of diet. It was shown that in the trophic network of the ecosystem of the estuary region of the Red River, at a higher trophic level of the food chain, the level of mercury accumulation was higher. Predators are characterized by a more intense accumulation of mercury (4—13 times) in muscle tissue compared to peaceful fish species. Positive reliable correlations between mercury content in fish and mercury concentrations in the water of the estuary area of the Red River are described. The content of mercury in the muscle tissue of marine fish has a significant and positive correlation with the concentration of suspended mercury.

Исследование проводилось в районе устья Красной реки в течение 6 лет. Превышение вьетнамских санитарных норм по содержанию ртути в пищевых продуктах наблюдалось у пресноводного сома (Clarias batrachus), змееголова (Channa Striata), восточного тунца (Euthynnus affinis), красного окуня (Lutjanus vitta) и восточной рыбы-мухоловки (Dactyloptena orientalis) (в 1,7; 1,2; 1,8; 1,3 и 1,1 раза соответственно). Приведены зависимости содержания ртути в мышечной ткани рыб от их массы, продуктов питания и трофического положения в пищевой цепи. Ведущую роль в накоплении ртути в организме рыб играет тип рациона. Было показано, что в трофической сети экосистемы района устья Красной реки, на более высоком трофическом уровне пищевой цепи уровень накопления ртути был выше. Хищники характеризуются более интенсивным накоплением ртути (в 4—13 раз) в мышечной ткани по сравнению с м ирными видами рыб. Описаны положительные достоверные корреляции между содержанием ртути в рыбе и концентрациями ртути в воде района устья Красной реки. Содержание ртути в мышечной ткани морских рыб имеет значительную и положительную корреляцию с концентрацией взвешенной ртути.

description: The present study examined the role of executive control functions (ECF) in adaptive risk-taking during adolescence. Healthy individuals aged 8–25 were administered ECF measures and the Balloon Analogue Risk Task (BART), a computerized measure of risk-taking propensity. Findings demonstrated that adolescents who executed a more consistent response strategy evidenced better performance on the BART. Greater working memory (WM) predicted lower response variability and WM capacity mediated the relationship between age and variability. Results suggest that intra-individual response variability may index adaptive risk-taking and that the development of ECF, specifically WM, may play an integral role in adaptive decision making during adolescence and young adulthood.

description: Dynamical networks are powerful tools for modeling a broad range of complex systems, including financial markets, brains, and ecosystems. They encode how the basic elements (nodes) of these systems interact altogether (via links) and evolve (nodes' dynamics). Despite substantial progress, little is known about why some subtle changes in the network structure, at the so-called critical points, can provoke drastic shifts in its dynamics. We tackle this challenging problem by introducing a method that reduces any network to a simplified low-dimensional version. It can then be used to describe the collective dynamics of the original system. This dimension reduction method relies on spectral graph theory and, more specifically, on the dominant eigenvalues and eigenvectors of the network adjacency matrix. Contrary to previous approaches, our method is able to predict the multiple activation of modular networks as well as the critical points of random networks with arbitrary degree distributions. Our results are of both fundamental and practical interest, as they offer a novel framework to relate the structure of networks to their dynamics and to study the resilience of complex systems.

description: Across mammalian species, solute exchange takes place in complex microvascular networks. In the human placenta, the primary exchange units are terminal villi that contain disordered networks of fetal capillaries and are surrounded externally by maternal blood. Here we show how the irregular internal structure of a terminal villus determines its exchange capacity for a wide range of solutes. Distilling geometric features into three scalar parameters, obtained from image analysis and computational fluid dynamics, we capture archetypal features of the the structure-function relationship of terminal villi using a simple algebraic approximation, revealing transitions between flow- and diffusion-limited transport at vessel and network levels. Our theory accommodates countercurrent effects, incorporates nonlinear blood rheology and offers an efficient method for testing network robustness. Our results show how physical estimates of solute transport, based on carefully defined geometrical statistics, provide a viable method for linking placental structure and function, and offer a framework for assessing transport in other microvascular systems.

description: In an article written by Giulio Magli on the orientation of the Roman towns, Bononia, the Roman Bologna, is given as a specific example to support Magli’s thesis on the existence of preferred solar alignments of the urban layout. Assuming that the Roman towns had been oriented to the sunrise on the day of their foundation, Magli suggested possible preferred alignments according to Roman festivals, in particular the festival of Terminalia. Of Bononia, we know the date of foundation as Roman colony in 189 BC, given by Livy. We will show that, according to Roman chronology and Republican calendar, it is impossible that Bononia had been oriented to the sunrise on the day given by Livy. The discrepancy is huge. Moreover, the direction of the decumanus cannot match the dates of Terminalia for 189 BC. However, if we consider that the layout that we see today is that of a recolonization under Octavian, we can have a certain agreement between the direction of the decumanus and the sunrise on the day of Terminalia (within three days), and a perfect agreement with the day of the festival of Armilustrium. In the proposed discussion, we will stress in particular the problem of the discrepancy between the historical dates of Roman chronology and the Julian dates, those that we can find according to an astronomical analysis. This problem is general and must be properly considered in any archaeoastronomical analysis of Roman towns.

The N N -> NN pi+ Reaction near Threshold in a Chiral Power Counting Approach

description: Power-counting arguments are used to organize the interactions contributing to the N N -> d pi, p n pi reactions near threshold. We estimate the contributions from the three formally leading mechanisms: the Weinberg-Tomozawa (WT) term, the impulse term, and the $Δ$-excitation mechanism. Sub-leading but potentially large mechanisms, including $S$-wave pion-rescattering, the Galilean correction to the WT term, and short-ranged contributions are also examined. The WT term is shown to be numerically the largest, and the other contributions are found to approximately cancel. Similarly to the reaction p p -> p p pi0, the computed cross sections are considerably smaller than the data. We discuss possible origins of this discrepancy.

description: New QCD-like `hypercolor' sectors can generate a broad class of new signatures at hadron colliders and furnish a variety of dark matter candidates. Paired diboson resonances are a particularly important collider signature, arising both from $CP$-conserving vector hypermeson decays of the form $\widetildeρ\rightarrow\widetildeπ\widetildeπ\rightarrow 4V$ and from $CP$-violating pseudoscalar hypermeson decays of the form $\widetildeη\rightarrow \widetildeπ\widetildeπ\rightarrow 4V$. The latter are sensitive to the vacuum angle $\widetilde θ$ in the hypercolor sector. We study single- and paired-diboson resonance signatures in final states involving gluons and photons at the LHC and a future 100 TeV $pp$ collider, illustrating the discovery potential at both colliders in simple benchmark models. We also describe some of the theoretical and cosmological consequences of $\widetilde θ$. If $CP$-violating hypermeson decays are observable at hadron colliders, ordinary QCD must have an axion. Such scenarios also provide a natural setting for a dark pion component of dark matter, with its relic abundance set by $CP$-violating annihilations. If the new vacuum angle is relaxed to zero by a dark axion, the relic density can instead be a mixture of axions and dark axions. Overproduction of dark axions is most easily avoided if the universe underwent a period of early matter domination.

Subjects: Financial analysis, Investment decisions, Stock exchange, Shares, Decision-making

description: Financial analysis (FA) plays a crucial role in decision-making processes, particularly in investment decisions within the stock exchange (SE). While FA serves various purposes beyond investing, its significance becomes heightened when used as a determinant for investment strategies. This study aims to investigate the extent to which investors in the stock exchange prioritize financial statement analysis when making investment decisions, focusing specifically on investments in shares.

The stock market encompasses a diverse array of securities, including shares and bonds. However, this study focuses solely on investments in shares, given their prominence within the stock exchange. By examining investors' attitudes and behaviors towards financial statement analysis, this research seeks to shed light on the role of FA in shaping investment decisions and strategies within the stock exchange.

Through empirical analysis and survey methodologies, this study explores the relationship between financial statement analysis and investment decisions in shares. Key factors influencing investors' consideration of FA in their investment processes are identified and analyzed, providing insights into the underlying mechanisms driving investment behavior within the stock exchange.

The findings of this study have significant implications for both individual investors and financial institutions operating within the stock exchange. By understanding the extent to which investors prioritize FA in their investment decisions, stakeholders can develop more effective investment strategies and tools tailored to investors' needs and preferences.

description: The basic Helix-Loop-Helix (bHLH) transcription factors SCREAM/ICE1 and SCREAM2 have well-characterized roles in the terminal differentiation of stomatal guard cells in Arabidopsis thaliana. Here we report on the characterization of the functional roles of the remaining members of sub-group IIIB, bHLH093 and bHLH061. The bhlh093/bhlh061 double mutant failed to produce a primary inflorescence shoot and displayed greater phenotypic severity than bhlh093 and bhlh061 single mutants. An ultrastructural investigation revealed structural defects that develop in tissues surrounding the meristem prior to inflorescence emergence. The transition to flowering was restored in bhlh093/bhlh061 with the application of gibberellin to the apex. We also demonstrate that gibberellin application alleviates structural defects that develop in tissues surrounding the meristem and restore meristem activity. Furthermore, the bhlh093/bhlh061 double mutant was affected by delayed flowering, and the severity of the phenotype correlated with photoperiod and light intensity. Our results indicate that bHLH093 and bHLH061 function in the gibberellin-mediated establishment of functional apical meristems during the transition from vegetative to reproductive growth.
Jamming in multilayer supervised learning models

description: Critical jamming transitions are characterized by an astonishing degree of universality. Analytic and numerical evidence points to the existence of a large universality class that encompasses finite and infinite dimensional spheres and continuous constraint satisfaction problems (CCSP) such as the non-convex perceptron and related models. In this paper we investigate multilayer neural networks (MLNN) learning random associations as models for CCSP which could potentially define different jamming universality classes. As opposed to simple perceptrons and infinite dimensional spheres, which are described by a single effective field in terms of which the constraints appear to be one-dimensional, the description of MLNN, involves multiple fields, and the constraints acquire a multidimensional character. We first study the models numerically and show that similarly to the perceptron, whenever jamming is isostatic, the sphere universality class is recovered, we then write the exact mean-field equations for the models and identify a dimensional reduction mechanism that leads to a scaling regime identical to one of the infinite dimensional spheres. We suggest that this mechanism could be general enough to explain finite dimensional universality.
