description: We solve exactly a model of monodispersed rigid rods of length $k$ with repulsive interactions on the random locally tree like layered lattice. For $k\geq 4$ we show that with increasing density, the system undergoes two phase transitions: first from a low density disordered phase to an intermediate density nematic phase and second from the nematic phase to a high density re-entrant disordered phase. When the coordination number is $4$, both the phase transitions are continuous and in the mean field Ising universality class. For even coordination number larger than $4$, the first transition is discontinuous while the nature of the second transition depends on the rod length $k$ and the interaction parameters.

description: Imitation learning has achieved great success in many sequential decision-making tasks, in which a neural agent is learned by imitating collected human demonstrations. However, existing algorithms typically require a large number of high-quality demonstrations that are difficult and expensive to collect. Usually, a trade-off needs to be made between demonstration quality and quantity in practice. Targeting this problem, in this work we consider the imitation of sub-optimal demonstrations, with both a small clean demonstration set and a large noisy set. Some pioneering works have been proposed, but they suffer from many limitations, e.g., assuming a demonstration to be of the same optimality throughout time steps and failing to provide any interpretation w.r.t knowledge learned from the noisy set. Addressing these problems, we propose {\method} by evaluating and imitating at the sub-demonstration level, encoding action primitives of varying quality into different skills. Concretely, {\method} consists of a high-level controller to discover skills and a skill-conditioned module to capture action-taking policies, and is trained following a two-phase pipeline by first discovering skills with all demonstrations and then adapting the controller to only the clean set. A mutual-information-based regularization and a dynamic sub-demonstration optimality estimator are designed to promote disentanglement in the skill space. Extensive experiments are conducted over two gym environments and a real-world healthcare dataset to demonstrate the superiority of {\method} in learning from sub-optimal demonstrations and its improved interpretability by examining learned skills.

description: We study the weak gravitational lensing effect of Non-Bocharova-Bronnikov-Melnikov-Bekenstein (BBMB) black hole in new massive conformal gravity. We analyze the deflection angle of light caused by new massive conformal gravity by using the gauss-bonnet theorem. As a consequence, we obtain the gaussian optical curvature and calculate the deflection angle of the new massive conformal gravity for spherically balanced spacetime with the gauss-bonnet theorem. The resultant deflection angle of light in the weak field limits showing that the bending of light is a global and topological phenomenon. Furthermore, we identify the deflection angle of light in the framework of the plasma medium, we also demonstrate the effect of a plasma medium on the deflection of light by non BBMB. In addition, the behavior of the deflection angle by new massive conformal gravity is explicitly shown in the influence of plasma medium and for the non plasma medium.

description: Personalized Federated Learning (PFL) which collaboratively trains a federated model while considering local clients under privacy constraints has attracted much attention. Despite its popularity, it has been observed that existing PFL approaches result in sub-optimal solutions when the joint distribution among local clients diverges. To address this issue, we present Federated Modular Network (FedMN), a novel PFL approach that adaptively selects sub-modules from a module pool to assemble heterogeneous neural architectures for different clients. FedMN adopts a light-weighted routing hypernetwork to model the joint distribution on each client and produce the personalized selection of the module blocks for each client. To reduce the communication burden in existing FL, we develop an efficient way to interact between the clients and the server. We conduct extensive experiments on the real-world test beds and the results show both the effectiveness and efficiency of the proposed FedMN over the baselines.
SUSY and tri-vector deformations

description: We analyze conditions for a tri-vector deformation of a supergravity background to preserve some supersymmetry. Working in the formalism of the SL(5) exceptional field theory, we present its supersymmetry transformations and introduce an additional USp(4) transformation to stay in the supergravity frame. This transformation acts on local indices and deforms BPS equations of exceptional field theory. The requirement for the deformation to vanish is the desired condition. The condition is shown to be consistent with previous results on bi-vector deformations.

description: Previous investigations have shown that SrPd2Ge2, a compound isostructural with "122" iron pnictides but iron- and pnictogen-free, is a conventional superconductor with a single s-wave energy gap and a strongly three-dimensional electronic structure. In this work we reveal the Abrikosov vortex lattice formed in SrPd2Ge2 when exposed to magnetic field by means of scanning tunneling microscopy and spectroscopy. Moreover, by examining the differential conductance spectra across a vortex and estimating the upper and lower critical magnetic fields by tunneling spectroscopy and local magnetization measurements, we show that SrPd2Ge2 is a strong type II superconductor with κ>> sqrt(2). Also, we compare the differential conductance spectra in various magnetic fields to the pair breaking model of Maki - de Gennes for dirty limit type II superconductor in the gapless region. This way we demonstrate that the type II superconductivity is induced by the sample being in the dirty limit, while in the clean limit it would be a type I superconductor with κ << sqrt(2), in concordance with our previous study (T. Kim et al., Phys. Rev. B 85, (2012)).

Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: Today's health care system has increasingly focused on health promotion and disease prevention activities. Within the United States' Air Force, emphasis has also been placed on health promoting lifestyle activities. However, the Air Force has a paucity of research regarding health promotion behavior and characteristics that influence a healthy lifestyle. The purpose of this research study was to determine the extent perceived locus of control and demographic factors, as selected factors of Nola Pender's Health Promotion Model, can predict health promotion behavior in a random sample of 217 active duty AF personnel assigned to a southwestern base. The results of the Multidimensional Health Locus of Control scale, Health Promotion Lifestyle Profile II, and a researcher-devised Biographical Data Sheet were analyzed using descriptive statistics and multiple regression. The findings of this study suggest that there is no predictive relationship between self-reported perceived locus control, demographic characteristics, and health promotion activities of active duty Air Force personnel.

description: Scientists are rigorously looking for an efficient vaccine against the current pandemic due to the SARS-CoV-2 virus. The reverse vaccinology approach may provide us with significant therapeutic leads in this direction and further determination of T-cell/B-cell response to antigen. In the present study, we conducted a population coverage analysis referring to the diverse Indian population. From the Immune epitope database (IEDB), HLA- distribution analysis was performed to find the most promiscuous T-cell epitope out of In silico determined epitope of Spike protein from SARS-CoV-2. Epitopes were selected based on their binding affinity with the maximum number of HLA alleles belonging to the highest population coverage rate values for the chosen geographical area in India. 404 cleavage sites within the 1288 amino acids sequence of spike glycoprotein were determined by NetChop proteasomal cleavage prediction suggesting the presence of adequate sites in the protein sequence for cleaving into appropriate epitopes. For population coverage analysis, 179 selected epitopes present the projected population coverage up to 97.45% with 56.16 average hit and 15.07 pc90. 54 epitopes are found with the highest coverage among the Indian population and highly conserved within the given spike RBD domain sequence. Among all the predicted epitopes, 9-mer TRFASVYAW and RFDNPVLPF along with 12-mer LLAGTITSGWTF and VSQPFLMDLEGK epitopes are observed as the best due to their decent docking score and best binding affinity to corresponding HLA alleles during MD simulations. Outcomes from this study could be critical to design a vaccine against SARS-CoV-2 for a different set of populations within the country. Communicated by Ramaswamy H. Sarma
The effect of caffeine on high-intensity, intermittent exercise to exhaustion
Creators: name: Herman, James Andrew
Publisher: name: University of Nevada, Las Vegas

description: Caffeine has been proported to increase endurance exercise time to exhaustion. However, the effects of caffeine on high-intensity, intermittent exercise to exhaustion have not been widely studied. Therefore, the purpose of this study was to examine the effect of caffeine on intermittent, high intensity exercise to exhaustion in individuals with minimal daily dietary caffeine consumption. Seven male participants, age 26 {dollar}\pm{dollar} 2 years, body mass 77 {dollar}\pm{dollar} 11 kg, and VO2{dollar}\rm\sb{max}{dollar} 47 {dollar}\pm{dollar} 7 ml/kg/min, performed a high-intensity exercise bout under both caffeine and placebo conditions administered in a counterbalanced, double blind fashion. Participants cycled at 120% of peak power output for 60 seconds followed by 120 seconds of recovery at 50 Watts. Work/rest cycles continued until voluntary exhaustion. Blood samples were taken immediately prior to administering caffeine or placebo beverages, one hour post absorption, and immediately following the conclusion of the exercise test. No significant difference in time to exhaustion was found between caffeine and placebo trials (12.5 {dollar}\pm{dollar} 5.9 vs 12.3 {dollar}\pm{dollar} 6.6 min), nor did peak blood lactate concentration differ between trials (11.3 {dollar}\pm{dollar} 1.0 vs 11.6 {dollar}\pm{dollar} 1.9 mM). These results suggest that caffeine treatment provides no significant improvement in performance time during intermittent, high-intensity exercise to exhaustion.

description: We develop a comprehensive framework to measure the impact of the climate transition on investment portfolios. Our analysis is enriched by including geographical, sectoral, company and ISIN-level data to assess transition risk. We find that investment funds suffer a moderate 5.7% loss upon materialization of a high transition risk scenario. However, the risk distribution is significantly left-skewed, with the worst 1% funds experiencing an average loss of 21.3%. In terms of asset classes, equities are the worst performers (-12.7%), followed by corporate bonds (-5.6%) and government bonds (-4.8%). We discriminate among financial instruments by considering the carbon footprint of specific counterparties and the credit rating, duration, convexity and volatility of individual exposures. We find that sustainable funds are less exposed to transition risk and perform better than the overall fund sector in the low-carbon transition, validating their choice as green investments.

description: We have analyzed high-resolution echelle spectra of red giant members for seven open clusters in the Galactic anticentre direction to explore their chemical positions. Cluster membership has been confirmed by radial velocity. The spread in temperatures and gravities being very small among the red giants, nearly the same stellar lines were employed for all stars thereby reducing the abundance errors: the errors of the average abundance for a cluster were generally in the 0.02 to 0.05 dex range. Our present sample covers Galactocentric distances of 8.3 to 11.3 kpc and an age range of 0.2 to 4.3 Gyr. A careful comparison of our results for the cluster NGC 2682 (M 67) to other high-resolution abundance studies in the literature shows general good agreement for almost all elements in common.

description: Mergers between a massive galaxy and a small gas-rich companion (minor mergers) have been proposed as a viable mechanism for triggering radio emission in an active galaxy. Until now the problem has been catching this sequence of events as they occur. With MRC B1221$-$423 we have an active radio galaxy that has only recently been triggered, and a companion galaxy that provides the "smoking gun". Using spectroscopic data taken with the VIMOS Integral Field Unit detector on the European Southern Observatory's Very Large Telescope, we have examined the distribution, ionization state and kinematics of ionized gas in this interacting system. We have also modelled the stellar continuum with synthesised spectra of stellar populations of different ages. From our study of the ionized gas, we have derived preliminary models for the geometry of the interaction, analysed the kinematic behaviour of the ionized gas, and examined the ionization mechanisms at work throughout the system. Our modelling of the stellar continuum allowed us to identify and date distinct stellar populations within the galaxy pair. We find evidence of multiple episodes of widespread starburst activity, and by dating these populations, we provide tentative insight into the history of the interaction.

Electron Localization in Rydberg States

description: We discuss the possibility of localizing an electron in a highly excited Rydberg state. The second-order correlation of emitted photons is the tool for the determination of electron position. This second-order correlation of emitted radiation and, therefore, the correlation of operators describing the acceleration of the electron allows for a partial localization of the electron in its orbit. The correlation function is found by approximating the transition matrix elements by their values in the classical limit. It is shown that the second-order correlation, depending on two times, is a function of the time difference and is a periodic function of this argument with the period equal to the period of the corresponding classical motion. The function has sharp maxima corresponding to large electron acceleration in the vicinity of the ``perihelion.'' This allows the localization of the electron in its consecutive approach to the perihelion point.

description: Background and context. Non-formal learning for K-12 computing education enables young people to learn about computing outside the formal curriculum. Many studies have reported on non-formal initiatives but it is not always clear what children and young people have gained from their participation. Objectives. This study set out to investigate non-formal learning initiatives by means of a systematic literature review. The two research questions addressed by the study are: (1) What has been the focus of recent computing education research about K-12 initiatives for young people and (2) What is the impact of non-formal K-12 computing initiatives? Method. A systematic literature review of computing education research was conducted, focused on non-formal initiatives for young people. Research was included from any country, but must be published in English between January 2015 and April 2021. Searches using key terms were performed across three databases. 88 studies were synthesised from over 400 initial results. Findings. The vast majority of studies reported on immersive multi-day settings such as summer camps run by universities (n= 67), with fewer (n=21) reporting on regular ongoing after-school or weekend clubs. The most popular affective outcomes measured by studies were self-efficacy (n=25) and interest (n=22). Measurement of cognitive outcomes, such as knowledge (n= 13) and skills (n=17), was less prevalent. 22 different topics were identified from the studies, with most studies being programming-heavy. The majority of papers measured the short-term impact of these interventions, and generally there was an inconsistent or incomplete reporting of learner characteristics across the studies. Implications. The lack of papers investigating regular after-school initiatives suggests that the majority of non-formal learners are not being studied or that summer school findings are being wrongly extrapolated to this setting. More rigorous research is needed for regular after-school and short-term non-formal contexts to ensure that this set of learners' experiences is understood and potentially improved.

description: A set of Mo/Si periodic multilayers is studied by non destructive analysis methods. The thickness of the Si layers is 5 nm while the thickness of the Mo layers changes from one multilayer to another, from 2 to 4 nm. This enables us to probe the effect of the transition between the amorphous to crystalline state of the Mo layers near the interfaces with Si on the optical performances of the multilayers. This transition results in the variation of the refractive index (density variation) of the Mo layers, as observed by x-ray reflectivity (XRR) at a wavelength of 0.154 nm. Combining x-ray emission spectroscopy and XRR, the parameters (composition, thickness and roughness) of the interfacial layers formed by the interaction between the Mo and Si layers are determined. However, these parameters do not evolve significantly as a function of the Mo thickness. It is observed by diffuse scattering at 1.33 nm that the lateral correlation length of the roughness strongly decreases when the Mo thickness goes from 2 to 3 nm. This is due to the development of Mo crystallites parallel to the multilayer surface.

description: Many countries have increased their focus on computing in primary and secondary education in recent years and the UK and Ireland are no exception. The four nations of the UK have distinct and separate education systems, with England, Scotland, Wales, and Northern Ireland offering different national curricula, qualifications, and teacher education opportunities; this is the same for the Republic of Ireland. This paper describes computing education in these five jurisdictions and reports on the results of a survey conducted with computing teachers. A validated instrument was localised and used for this study, with 512 completed responses received from teachers across all five countries The results demonstrate distinct differences in the experiences of the computing teachers surveyed that align with the policy and provision for computing education in the UK and Ireland. This paper increases our understanding of the differences in computing education provision in schools across the UK and Ireland, and will be relevant to all those working to understand policy around computing education in school.
Decreasing incivility in an acute care pediatric setting using professional comportment
Creators: name: Robinson, Jasmin
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of the Project This DNP project evaluated the effectiveness of a professional comportment seminar in managing instances of incivility. Incivility is evidenced by subtle disruptive behaviors such as passive aggression or by overt forms of disruptive behavior such as yelling and berating. Incivility among nurses increases turnover, decreases retention, and creates unsafe patient conditions. A 3-part workshop was developed in response to identified barriers identified and offered at an urban medical center. Methodology This educational series used a pretest and posttest design. Participants completed the Healthy Workforce Disruptive behavior survey (HWI-DBS) to measure witnessed and experienced incivility. Participants also completed the General Self-Efficacy (GSE) tool before and after the workshops to determine skills acquisition in managing incivility. Results There was a total of 41 preintervention participants who broadly acknowledged personal experiences in witnessing and experiencing incivility Before the seminar, nurses identified frequent barriers to professional comportment, which shaped the training. Participants were noted to have witnessed more acts of incivility than actually experiencing instances of incivility (z = -3.058, p=0.002). When compared to demographics, incivility was noted across all age groups as a universal concept. After the seminar, nurses (n = 6) had increased scores on skills acquisition (z=-2.381, p=0.015). The small sample size was a marked limitation. Implications for Practice These results suggest that leaders should ensure that incivility training is mandated for staff to allow a greater impact on decreasing incivility. In addition, leaders must conduct frequent assessments measuring incivility to determine the best timing and offering of educational support.

description: The purpose of this study was to determine whether pets have a positive impact on the lives of their owners by improving their quality of life (QoL). In addition, the study examined the relationship between pet bonding, selected demographic variables and QoL among pet owners and non-pet owners; The subjects consisted of 136 pet owners and 101 non-pet owners from selected church congregations in a Southwestern state. Results of the t-test indicated no significant difference in the QoL scores between pet owners and non-pet owners (p =.232). Yet on a qualitative level, pet owners (90.3%), felt that their pet did affect their QoL; Qualitatively, five major themes were represented. The largest supported theme was that pets provide unconditional love and companionship, followed by emotional and social support, increased laughter and entertainment, increased physical activity and lastly, a feeling of security and protection.

description: Let $k$ be a field, $\tilde{G}$ a connected reductive $k$-group, and $Γ$ a finite group. In a previous work, the authors defined what it means for a connected reductive $k$-group $G$ to be "parascopic" for $(\tilde{G},Γ)$. Roughly, this is a simultaneous generalization of several settings. For example, $Γ$ could act on $\tilde{G}$, and $G$ could be the connected part of the group of $Γ$-fixed points in $\tilde{G}$. Or $G$ could be an endoscopic group, a pseudo-Levi subgroup, or an isogenous image of $\tilde{G}$. If $G$ is such a group, and both $\tilde{G}$ and $G$ are $k$-quasisplit, then we constructed a map $\hat{\mathcal{N}}^{\text{st}}$ from the set of stable semisimple conjugacy classes in the dual $G^\wedge(k)$ to the set of such classes in $\tilde{G}^\wedge(k)$. When $k$ is finite, this implies a lifting from packets of representations of $G(k)$ to those of $\tilde{G}(k)$. In order to understand such a lifting better, here we describe two ways in which $\hat{\mathcal{N}}^{\text{st}}$ can be made more explicit. First, we can express our map in the general case in terms of simpler cases. We do so by showing that $\hat{\mathcal{N}}^{\text{st}}$ is compatible with isogenies and with Weil restriction, and also by expressing it as a composition of simpler maps. Second, in many cases we can construct an explicit $k$-morphism $\hat N \colon G^\wedge \longrightarrow \tilde{G}^\wedge$ that agrees with $\hat{\mathcal{N}}^{\text{st}}$. As a consequence, our lifting of representations is seen to coincide with Shintani lifting in some important cases.

description: The goal of this paper is to study the spatial distribution of HNCO in massive star-forming regions, and investigate its spatial association with infrared sources, as well as physical conditions in region of HNCO emission. We have mapped nine massive star-forming regions in HNCO 5$_{05}-4_{04}$ with the Purple Mountain Observatory 13.7m telescope. The C18O maps of these sources were obtained simultaneously. The HNCO emission shows compact distribution, with emission peak centred on water masers. Nearly all the HNCO clumps show signs of embedded mid-infrared or far-infrared sources. The FWHM sizes of HNCO clumps are significantly smaller than C18O clumps but rather similar to HC3N clumps. We also found good correlation between the integrated intensities, linewidths and LSR velocities of HNCO and HC3N emission, implying similar excitation mechanism of these two species. As such, collisional excitation is likely to be the dominant excitation mechanism for HNCO 5$_{05}-4_{04}$ emission in galactic massive star-forming regions.

description: Renewable and sustainable energy is one of the most important challenges currently facing mankind. Wind has made an increasing contribution to the world's energy supply mix, but still remains a long way from reaching its full potential. In this paper, we investigate the use of artificial evolution to design vertical-axis wind turbine prototypes that are physically instantiated and evaluated under approximated wind tunnel conditions. An artificial neural network is used as a surrogate model to assist learning and found to reduce the number of fabrications required to reach a higher aerodynamic efficiency, resulting in an important cost reduction. Unlike in other approaches, such as computational fluid dynamics simulations, no mathematical formulations are used and no model assumptions are made.

description: Direct numerical simulations are used to investigate the individual dynamics of large spherical particles suspended in a developed homogeneous turbulent flow. A definition of the direction of the particle motion relative to the surrounding flow is introduced and used to construct the mean fluid velocity profile around the particle. This leads to an estimate of the particle slipping velocity and its associated Reynolds number. The flow modifications due to the particle are then studied. The particle is responsible for a shadowing effect that occurs in the wake up to distances of the order of its diameter: the particle pacifies turbulent fluctuations and reduces the energy dissipation rate compared to its average value in the bulk. Dimensional arguments are presented to draw an analogy between particle effects on turbulence and wall flows. Evidence is obtained on the presence of a logarithmic sublayer at distances between the thickness of the viscous boundary layer and the particle diameter $\Dp$. Finally, asymptotic arguments are used to relate the viscous sublayer quantities to the particle size and the properties of the outer turbulence. It is shown in particular that the skin-friction Reynolds number behaves as $Re_τ\propto (\Dp/η)^{4/3}$.

Instructional environments for technology inservice education
Creators: name: Grove, Karen Jane
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: This study examines different instructional formats for providing inservice education on classroom technology applications to elementary teachers. An intensive weekend workshop format was compared with a traditionally paced format for inservice education. Results are discussed in terms of measurable changes in teacher growth in the use of the applications and growth in the use of the applications with students. A secondary purpose was to determine if there was a relationship between learning styles and success in these two environments. Teachers' learning styles were identified using the Myers-Briggs Type Indicator. The results of the study indicate that intensive models of inservice education are as effective as traditional models in this context. The study was inconclusive with respect to learning styles relationships; however the data suggest that further research is warranted.
Mass transport perspective on an accelerated exclusion process: Analysis of augmented current and unit-velocity phases

description: In an accelerated exclusion process (AEP), each particle can "hop" to its adjacent site if empty as well as "kick" the frontmost particle when joining a cluster of size $\ell \leq \ell_\text{max}$. With various choices of the interaction range, $\ell_\text{max}$, we find that the steady state of AEP can be found in a homogeneous phase with augmented currents (AC) or a segregated phase with holes moving at unit velocity (UV). Here we present a detailed study on the emergence of the novel phases, from two perspectives: the AEP and a mass transport process (MTP). In the latter picture, the system in the UV phase is composed of a condensate in coexistence with a fluid, while the transition from AC to UV can be regarded as condensation. Using Monte Carlo simulations, exact results for special cases, and analytic methods in a mean field approach (within the MTP), we focus on steady state currents and cluster sizes. Excellent agreement between data and theory is found, providing an insightful picture for understanding this model system.

description: In order to study as a whole a wide part of entropy measures, we introduce a two-parameter non-extensive entropic form with respect to the $h$-derivative, which generalizes the conventional Newton--Leibniz calculus. This new entropy, $S_{h,h'}$, is proved to describe the non-extensive systems and recover several types of well-known non-extensive entropic expressions, such as the Tsallis entropy, the Abe entropy, the Shafee entropy, the Kaniadakis entropy and even the classical Boltzmann--Gibbs one. As a generalized entropy, its corresponding properties are also analyzed.

Scalar Material Reference Systems and Loop Quantum Gravity

description: In the past, the possibility to employ (scalar) material reference systems in order to describe classical and quantum gravity directly in terms of gauge invariant (Dirac) observables has been emphasised frequently. This idea has been picked up more recently in Loop Quantum Gravity (LQG) with the aim to perform a reduced phase space quantisation of the theory thus possibly avoiding problems with the (Dirac) operator constraint quantisation method for constrained system. In this work, we review the models that have been studied on the classical and/or the quantum level and parametrise the space of theories so far considered. We then describe the quantum theory of a model that, to the best of our knowledge, so far has only been considered classically. This model could arguably called the optimal one in this class of models considered as it displays the simplest possible true Hamiltonian while at the same time reducing all constraints of General Relativity.

Computer-controlled stereoscopic profiling
Creators: name: Grayson, Neil Scott
Publisher: name: University of Nevada, Las Vegas
Year: 1997

description: This paper presents a computer controlled stereoscopic vision system that will profile the contour and shape of the bottom of the human foot in its natural weight bearing position. The design will have no moving parts and will be restricted to an error of no more than {dollar}\pm{dollar}1 mm; Stereoscopic vision was chosen as the solution to profiling mainly because its use for this purpose is well documented. It is used in many fields that require range resolution. Mechanical engineers have used it in the development of robot vision for years and their applications range from control systems for robot welding to the determination of metal fatigue in aircraft (2). Radar engineers have used it since the early 1940's to determine the range of incoming flying objects (1). Many other fields have used it for even more far reaching purposes. Our use is another in that long list.

description: We introduce a general method to induce Bridgeland stability conditions on semiorthogonal components of triangulated categories. In particular, we prove the existence of Bridgeland stability conditions on the Kuznetsov component of the derived category of Fano threefolds and of cubic fourfolds. As an application, in the appendix, written jointly with Xiaolei Zhao, we give a variant of the proof of the Torelli theorem for cubic fourfolds by Huybrechts and Rennemo.

The growth rate of harmonic functions

description: We study the growth rate of harmonic functions in two aspects: gradient estimate and frequency. We obtain the sharp gradient estimate of positive harmonic function in geodesic ball of complete surface with nonnegative curvature. On complete Riemannian manifolds with non-negative Ricci curvature and maximal volume growth, further assume the dimension of the manifold is not less than three, we prove that quantitative strong unique continuation yields the existence of nonconstant polynomial growth harmonic functions. Also the uniform bound of frequency for linear growth harmonic functions on such manifolds is obtained, and this confirms a special case of Colding-Minicozzi conjecture on frequency.

A variational principle for cyclic polygons with prescribed edge lengths

Subjects: subject: Metric Geometry (math.MG)

description: We provide a new proof of the elementary geometric theorem on the existence and uniqueness of cyclic polygons with prescribed side lengths. The proof is based on a variational principle involving the central angles of the polygon as variables. The uniqueness follows from the concavity of the target function. The existence proof relies on a fundamental inequality of information theory. We also provide proofs for the corresponding theorems of spherical and hyperbolic geometry (and, as a byproduct, in $1+1$ spacetime). The spherical theorem is reduced to the euclidean one. The proof of the hyperbolic theorem treats three cases separately: Only the case of polygons inscribed in compact circles can be reduced to the euclidean theorem. For the other two cases, polygons inscribed in horocycles and hypercycles, we provide separate arguments. The hypercycle case also proves the theorem for "cyclic" polygons in $1+1$ spacetime.

GENERIC formalism of a Vlasov-Fokker-Planck equation and connection to large-deviation principles

description: In this paper we discuss the connections between a Vlasov-Fokker-Planck equation and an underlying microscopic particle system, and we interpret those connections in the context of the GENERIC framework (Öttinger 2005). This interpretation provides (a) a variational formulation for GENERIC systems, (b) insight into the origin of this variational formulation, and (c) an explanation of the origins of the conditions that GENERIC places on its constitutive elements, notably the so-called degeneracy or non-interaction conditions. This work shows how the general connection between large-deviation principles on one hand and gradient-flow structures on the other hand extends to non-reversible particle systems.
A new bio-active asymmetric-Schiff base: synthesis and evaluation of calf thymus DNA interaction, topoisomerase IIα inhibition, in vitro antiproliferative activity, SEM analysis and molecular docking studies

description: In this paper, the asymmetric-Schiff base 2-(4-(2-hydroxybenzylideneamino)benzylideneamino)benzoic acid (SB-2) was newly synthesized and characterized by various spectroscopic methods. The interaction of SB-2 with calf thymus DNA was investigated by UV–vis, fluorescence spectroscopy and molecular docking methods. It was determined that SB-2 effectively binds to DNA via the intercalation mode. DNA electrophoretic mobility experiments displayed that topoisomerase IIα could not cleave pBR322 plasmid DNA in the presence of SB-2, confirming that the Schiff base acts as a topo II suppressor. In the molecular docking studies, SB-2 was found to show an affinity for both the DNA-topoisomerase IIα complex and the DNA. In vitro antiproliferative activity of SB-2 was screened against HT-29 (colorectal) and HeLa (cervical) human tumor cell lines by MTT assay. SB-2 diminished the cell viability in a concentration- and incubation time-dependent manner. The ability of SB-2 to measure DNA damage in tumor cells was evaluated with cytokinesis-block micronucleus assay after incubation 24 h and 48 h. Light and scanning electron microscopy experiments of tumor cells demonstrated an incubation time-dependent increase in the proportion of apoptotic cells (nuclear condensation and apoptotic bodies) suggesting that autophagy and apoptosis play a role in the death of cells. Based on the obtained results, it may be considered that SB-2 is a candidate for DNA-targeting antitumor drug. Communicated by Ramaswamy H. Sarma
