description: The anomalies in five-dimensional orbifold theories are examined in a generic type of non-factorizable geometries. In spite of complicated fermion wavefunctions, the shape of anomaly is found to be identical to that of flat theories. In particular it is split evenly on the orbifold fixed points. This result also follows from the arguments on the AdS/CFT correspondence and an anomaly cancellation mechanism. The cancellation with Chern-Simons term works if the four-dimensional effective theory is free from chiral anomalies. We also discuss the Fayet-Iliopoulos (FI) term in warped supersymmetric theories. Unlike the gauge anomaly, FI divergences reside not only on the orbifold fixed points but also in the whole five-dimensional bulk. The effect of the FI term is to generate supersymmetric masses for charged hypermultiplets, which are no longer constant but have metric factor dependence. We calculate the spectrum and wavefunctions of Kaluza-Klein modes in the presence of the FI term and discuss phenomenological implications to quark-lepton masses and large scale hierarchies.

description: With the proliferation of user-generated articles over the web, it becomes imperative to develop automated methods that are aware of the ideological-bias implicit in a document collection. While there exist methods that can classify the ideological bias of a given document, little has been done toward understanding the nature of this bias on a topical-level. In this paper we address the problem of modeling ideological perspective on a topical level using a factored topic model. We develop efficient inference algorithms using Collapsed Gibbs sampling for posterior inference, and give various evaluations and illustrations of the utility of our model on various document collections with promising results. Finally we give a Metropolis-Hasting inference algorithm for a semi-supervised extension with decent results
An investigation of chaotic diffusion in a family of Hamiltonian mappings whose angles diverge in the limit of vanishingly action

description: The chaotic diffusion for a family of Hamiltonian mappings whose angles diverge in the limit of vanishingly action is investigated by using the solution of the diffusion equation. The system is described by a two-dimensional mapping for the variables action, $I$, and angle, $θ$ and controlled by two control parameters: (i) $ε$, controlling the nonlinearity of the system, particularly a transition from integrable for $ε=0$ to non-integrable for $ε\ne0$ and; (ii) $γ$ denoting the power of the action in the equation defining the angle. For $ε\ne0$ the phase space is mixed and chaos is present in the system leading to a finite diffusion in the action characterized by the solution of the diffusion equation. The analytical solution is then compared to the numerical simulations showing a remarkable agreement between the two procedures.

description: The Pinyin Tutor has been used the past few years at over thirty institutions around the world to teach students to transcribe spoken Chinese phrases into Pinyin. Large amounts of data have been collected from this program on the types of errors students make on this task. We analyze these data to discover what makes this task difficult and use our findings to iteratively improve the tutor. For instance, is a particular set of consonants, vowels, or tones causing the most difficulty? Or perhaps do certain challenges arise in the context in which these sounds are spoken? Since each Pinyin phrase can be broken down into a set of features (for example, consonants, vowel sounds, and tones), we apply machine learning techniques to uncover the most confounding aspects of this task. We then exploit what we learned to construct and maintain an accurate representation of what the student knows for best individual instruction. Our goal is to allow the learner to focus on the aspects of the task on which he or she is having most difficulty, thereby accelerating his or her understanding of spoken Chinese beyond what would be possible without such focused “intelligent” instruction.

description: В данное время остро стоит вопрос о необходимости внедрения новых механизмов управления промышленными предприятиями, которые могли бы не только предлагать имеющиеся и новые инструменты управления, но и позволяли производить корреляционную оценку предлагаемого инструментария, а также расширяли бы возможность промышленных предприятий с точки зрения получаемых средств. У большинства промышленных предприятий в последнее время увеличивается количество нематериальных активов, признаваемых в финансовой отчетности (хотя доля их по-прежнему невелика). Это связано с расширением бизнеса, созданием новых товарных знаков, внедрением дорогостоящих информационных систем. В статье получили дальнейшее углубление и развитие существующие в современной экономической науке теоретические и методические основы решения проблемы инструментария управления эффективностью деятельности промышленных предприятий.

description: We have obtained UKIRT infrared observations of the field of the bright Galactic Z source GX5-1. From an astrometric plate solution tied to Tycho-ACT standards we have obtained accurate positions for the stars in our field which, combined with an accurate radio position, have allowed us to identify the probable infrared counterpart of GX5-1. Narrow-band photometry marginally suggests excess Br-gamma emission in the counterpart, supporting its association with an accretion-disc source. No significant variability is observed in a limited number of observations. We compare the H and K magnitudes with those of other Z sources, and briefly discuss possible sources of infrared emission in these systems.

description: We describe a framework for designing efficient active learning algorithms that are tolerant to random classification noise and are differentially-private. The framework is based on active learning algorithms that are statistical in the sense that they rely on estimates of expectations of functions of filtered random examples. It builds on the powerful statistical query framework of Kearns (JACM 45(6):983–1006, 1998). We show that any efficient active statistical learning algorithm can be automatically converted to an efficient active learning algorithm which is tolerant to random classification noise as well as other forms of “uncorrelated” noise. The complexity of the resulting algorithms has information-theoretically optimal quadratic dependence on1/(1−2η), whereηis the noise rate. We show that commonly studied concept classes including thresholds, rectangles, and linear separators can be efficiently actively learned in our framework. These results combined with our generic conversion lead to the first computationally-efficient algorithms for actively learning some of these concept classes in the presence of random classification noise that provide exponential improvement in the dependence on the errorϵover their passive counterparts. In addition, we show that our algorithms can be automatically converted to efficient active differentially-private algorithms. This leads to the first differentially-private active learning algorithms with exponential label savings over the passive case.

description: High density clusters can be characterized by the connected components of a level set L(λ) = {x: p(x)>λ} of the underlying probability density function p generating the data, at some appropriate level λ ≥ 0. The complete hierarchical clustering can be characterized by a cluster tree T= ∪λL(λ). In this paper, we study the behavior of a density level set estimate L̂(λ) and cluster tree estimate T̂ based on a kernel density estimator with kernel bandwidth h. We define two notions of instability to measure the variability of L̂(λ) and T̂ as a function of h, and investigate the theoretical properties of these instability measures.
From Stars to Super-planets: the Low-Mass IMF in the Young Cluster IC348

description: We investigate the low-mass population of the young cluster IC348 down to the deuterium-burning limit, a fiducial boundary between brown dwarf and planetary mass objects, using a new and innovative method for the spectral classification of late-type objects. Using photometric indices, constructed from HST/NICMOS narrow-band imaging, that measure the strength of the 1.9 micron water band, we determine the spectral type and reddening for every M-type star in the field, thereby separating cluster members from the interloper population. Due to the efficiency of our spectral classification technique, our study is complete from approx 0.7 Msun to 0.015 Msun. The mass function derived for the cluster in this interval, dN/dlogM \propto M^{0.5}, is similar to that obtained for the Pleiades, but appears significantly more abundant in brown dwarfs than the mass function for companions to nearby sun-like stars. This provides compelling observational evidence for different formation and evolutionary histories for substellar objects formed in isolation vs. as companions. Because our determination of the IMF is complete to very low masses, we can place interesting constraints on the role of physical processes such as fragmentation in the star and planet formation process and the fraction of dark matter in the Galactic halo that resides in substellar objects.

Simulations of the Chain Length Dependence of the Melting Mechanism in Short-Chained n-alkane Monolayers on Graphite

description: The melting transition in solid monolayers of a series of short-chained n-alkanes, n-octane (n-C8H18), n-decane (n-C10H22), and n-dodecane (n-C12H26) physisorbed onto the graphite basal plane are studied through use of molecular dynamics simulations. Utilizing previous experimental observations of the solid phase behavior of these monolayers, this study investigates the temperature dependence of the phases and phase transitions in these three monolayers during the solid-fluid phase transition, and compares the observed melting behavior to previous studies of hexane and butane monolayers. In particular, this study seems to indicate a greater dependence of the melting transition on the formation of gauche defects in the alkyl chains as the chain length is increased. In light of the previously proposed footprint reduction mechanism and variations where the formation of gauche defects are energetically negated, simulations seem to suggest that decane and dodecane monolayers are generally equally as dependent upon the formation of gauche defects for the melting transition to take place, whereas octane monolayers seem to have less dependence, but follow a trend that is established in previous studies of melting in butane and hexane monolayers. Also, the phase transition from a solid herringbone phase into an orientationally ordered intermediate phase is found to exhibit some differences as compared to a recent study of hexane monolayers, which may be interpreted as originating from the greater influence of gauche defects. Comparison to experimental melting temperatures is provided where possible, and applications involving thin film manipulation and lubrication is discussed.

description: MOTIVATION: Microarray profiling of mRNA abundance is often ill suited for temporal-spatial analysis of gene expressions in multicellular organisms such as Drosophila. Recent progress in image-based genome-scale profiling of whole-body mRNA patterns via in situ hybridization (ISH) calls for development of accurate and automatic image analysis systems to facilitate efficient mining of complex temporal-spatial mRNA patterns, which will be essential for functional genomics and network inference in higher organisms. RESULTS: We present SPEX(2), an automatic system for embryonic ISH image processing, which can extract, transform, compare, classify and cluster spatial gene expression patterns in Drosophila embryos. Our pipeline for gene expression pattern extraction outputs the precise spatial locations and strengths of the gene expression. We performed experiments on the largest publicly available collection of Drosophila ISH images, and show that our method achieves excellent performance in automatic image annotation, and also finds clusters that are significantly enriched, both for gene ontology functional annotations, and for annotation terms from a controlled vocabulary used by human curators to describe these images.

Relativistic Mean-Field Theory and the High-Density Nuclear Equation of State

Year: 1996
Subjects: subject: Nuclear Theory (nucl-th)

description: The properties of high-density nuclear and neutron matter are studied using a relativistic mean-field approximation to the nuclear matter energy functional. Based on ideas of effective field theory, nonlinear interactions between the fields are introduced to parametrize the density dependence of the energy functional. Various types of nonlinearities involving scalar-isoscalar ($σ$), vector-isoscalar ($ω$), and vector-isovector ($ρ$) fields are studied. After calibrating the model parameters at equilibrium nuclear matter density, the model and parameter dependence of the resulting equation of state is examined in the neutron-rich and high-density regime. It is possible to build different models that reproduce the same observed properties at normal nuclear densities, but which yield maximum neutron star masses that differ by more than one solar mass. Implications for the existence of kaon condensates or quark cores in neutron stars are discussed.

description: The study aimed at phytochemical profiling and evaluating the bioactive potentials of aqueous bark extracts of a mangrove plant Avicennia officinalis by in vitro and in silico techniques. The quantitative phytochemical study exhibited total phenol and total flavonoid content as 16.6 mg GAE/g and 82 mg QE/g respectively. The GC-MS study indicated presence of five major compounds viz. 2,6-dimethoxy phenol; 4-[(1E)-3-hydroxy-1-propenyl)- 2-methoxy phenol; 2,5-dimethoxybenzyl acetate; vitamin-E; stigmasterol. The in silico molecular docking of compounds 2,6-dimethoxy phenol; 2,5-dimethoxy benzene methanol acetate and stigmasterol indicated strong binding interactions, validating the antiradical, antidiabetic, anti-inflammatory and antibacterial activities. The extract exhibited DPPH, ABTS, α-glucosidase and protein denaturation inhibition activities with IC50 values of 112.78, 76.34, 257.4, 99.86 μg/mL respectively suggesting the antioxidant, antidiabetic and anti-inflammatory potential of the plant. The antiglycation study exhibited inhibition of fructosamine and congo red with 50.63% and 64.39% at 200 μg/mL concentration. The biofilm inhibitory concentration required to reduce biofilm coverage by 50% values for the extract was 625 μg/mL. The results provide a basis for new pharmacological avenues and further research of this plant.

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

description: We argue that T-duality and F-theory appear automatically in the E_8 gauge bundle perspective of M-theory. The 11-dimensional supergravity four-form determines an E_8 bundle. If we compactify on a two-torus, this data specifies an LLE_8 bundle where LG is a centrally-extended loopgroup of G. If one of the circles of the torus is smaller than sqrt(alpha') then it is also smaller than a nontrivial circle S in the LLE_8 fiber and so a dimensional reduction on the total space of the bundle is not valid. We conjecture that S is the circle on which the T-dual type IIB theory is compactified, with the aforementioned torus playing the role of the F-theory torus. As tests we reproduce the T-dualities between NS5-branes and KK-monopoles, as well as D6 and D7-branes where we find the desired F-theory monodromy. Using Hull's proposal for massive IIA, this realization of T-duality allows us to confirm that the Romans mass is the central extension of our LE_8. In addition this construction immediately reproduces the conjectured formula for global topology change from T-duality with H-flux.

description: The large scale matter distribution in three different simulations of CDM models is investigated and compared with corresponding results of the Zel'dovich theory of nonlinear gravitational instability. We show that the basic characteristics of wall-like structure elements are well described by this theory, and that they can be expressed by the cosmological parameters and a few spectral moments of the perturbation spectrum. Therefore the characteristics of such elements provide reasonable estimates of these parameters. We show that the compressed matter is relaxed and gravitationally confined, what manifests itself in the existence of walls as (quasi)stationary structure elements with life time restricted by their disruption into high density clouds. The matter distribution is investigated both in the real and redshift spaces. In both cases almost the same particles form the walls, and we estimate differences in corresponding wall characteristics. The same methods are applied to several mock catalogues of 'galaxies' what allows us to characterize a large scale bias between the spatial distribution of dark matter and of simulated `galaxies'.

description: We demonstrate intracavity plasmonic laser spectroscopy using a plasmonic laser created from a periodically-perforated silver film with a liquid gain medium. An active zone of the laser is formed by a highly elongated spot of pumping. This results in an 80x decrease in the threshold pumping level; in a significantly more efficient diffusive mixing of dye molecules, which substantially suppresses the effect of their bleaching; and in the ability to reduce the volume of the gain medium to as little as 400 nL. We use this design for a stable plasmonic laser in multiple measurements and demonstrate that it is highly effective as a spaser spectroscopy sensor for intracavity detection of an absorptive dye at 70 ppb. This work provides an opportunity to develop applications of intracavity plasmonic laser spectroscopy in biological label detection and other fields.

description: The fused lasso was proposed recently to enable recovery of high-dimensional patterns which are piece-wise constant on a graph, by penalizing the ℓ1-norm of differences of measurements at vertices that share an edge. While there have been some attempts at coming up with efficient algorithms for solving the fused lasso optimization, a theoretical analysis of its performance is mostly lacking except for the simple linear graph topology. In this paper, we investigate sparsistency of fused lasso for general graph structures, i.e. its ability to correctly recover the exact support of piece-wise constant graphstructured patterns asymptotically (for largescale graphs). To emphasize this distinction over previous work, we will refer to it as Edge Lasso. We focus on the (structured) normal means setting, and our results provide necessary and sufficient conditions on the graph properties as well as the signal-to-noise ratio needed to ensure sparsistency. We examplify our results using simple graph-structured patterns, and demonstrate that in some cases fused lasso is sparsistent at very weak signal-to-noise ratios (scaling as p (log n)/|A|, where n is the number of vertices in the graph and A is the smallest set of vertices with constant activation). In other cases, it performs no better than thresholding the difference of measurements at vertices which share an edge (which requires signal-to-noise ratio that scales as √ log n).

Monsieur

J'étois venu à Paris pour des affaires de famille et par des circonstances accumulées, j'ai été contraint de m'y fixer. Mes amis m'ont procuré un privilège pour un journal dont vous avez cy joint le prospectus. Oserais-je vous prier de le répandre dans votre ville et de me procurer par vous même des soucripteurs. Faites moi l'amitié d'en remettre chez le principal libraire de Nismes et de lui faire dire que je lui donnerai suivant la coutume une provision de 10 pour 100 à condition qu'il recevra l'argent des souscriptions, qu'il m'en fera toucher le montant à Paris franc de port, soit en lettres de change à vue et bonne, soit en argent comptant. Les souscripteurs recevront leurs quittances en recevant le premier volume.

Quand je dis que je donnerai 10 pour 100 au libraire, c'est en ne comptant la souscription que 30 lt. parce que les six livres en sus sont pour la poste et que cet argent n'entre point dans ma poche.

Un journaliste a besoin d'être prôné, et si vous daignez me rendre ce service il est certain que votre réputation me donnera de la consistance.

[fol. 4655v] Oserai[-je] encore vous prier de me communiquer les mémoires qu'on lira à votre académie, concernants les trois parties que je traite. Si vous avez des occasions, vous pouvez les adresser à Lyon à Mrs Faure et Méca négotians place des Terreaux à Lyon qui me les feront parvenir.

Vous allez trouver ma demande indiscrette et je sens tout l'embarras dans lequel je vous jette. Vous aimez à obliger, voilà mon titre et mon excuse. Daignez conserver votre estime pour celui qui vous a voué les sentimens du plus sincère attachement et de la considération la plus respectueuse avec laquelle il a l'honneur d'être,

These structures may be members of a fragmentation hierarchy proceeding from sheets, to filaments, to elongated, prolate clumps. The embedded solutions are the first of their kind, and as such represent a significant improvement upon the isolated cloud paradigm used almost exclusively by previous authors. The properties of the equilibria are in reasonable agreement with observations of dense molecular cores in star-forming clouds, despite the fact that there is only one free parameter in the models. We show that this parameter may be identified with the critical wavelength for instability in the parent filament. The implications of further fragmentation and the possible influence of magnetic fields are briefly discussed.

description: The fast evaporative cooling of micrometer-sized water droplets in vacuum offers the appealing possibility to investigate supercooled water - below the melting point but still a liquid - at temperatures far beyond the state-of-the-art. However, it is challenging to obtain a reliable value of the droplet temperature under such extreme experimental conditions. Here, the observation of morphology-dependent resonances in the Raman scattering from a stream of perfectly uniform water droplets has allowed us to measure with an absolute precision of better than 0.2% the variation in droplet size resulting from evaporative mass losses. This finding proved crucial to an unambiguous determination of the droplet temperature. In particular, a fraction of water droplets with initial diameter of 6379$\pm$12 nm were found to remain liquid down to 230.6$\pm$0.6 K. Our results question temperature estimates reported recently for larger supercooled water droplets, and provide valuable information on the hydrogen-bond network in liquid water in the hard-to-access deeply supercooled regime.

description: We present sparse topical coding (STC), a non-probabilistic formulation of topic models for discovering latent representations of large collections of data. Unlike probabilistic topic models, STC relaxes the normalization constraint of admixture proportions and the constraint of defining a normalized likelihood function. Such relaxations make STC amenable to: 1) directly control the sparsity of inferred representations by using sparsity-inducing regularizers; 2) be seamlessly integrated with a convex error function (e.g., SVM hinge loss) for supervised learning; and 3) be efficiently learned with a simply structured coordinate descent algorithm. Our results demonstrate the advantages of STC and supervised MedSTC on identifying topical meanings of words and improving classification accuracy and time efficiency.

description: Renewables are key enablers in the plight to reduce greenhouse gas emissions and cope with anthropogenic global warming. The intermittent nature and limited storage capabilities of renewables culminate in new challenges that power system operators have to deal with in order to regulate power quality and ensure security of supply. At the same time, the increased availability of advanced automation and communication technologies provides new opportunities for the derivation of intelligent solutions to tackle the challenges. Previous work has shown various new methods of operating highly interconnected power grids, and their corresponding components, in a more effective way. As a consequence of these developments, the traditional power system is being transformed into a cyber-physical energy system, a smart grid. Previous and ongoing research have tended to mainly focus on how specific aspects of smart grids can be validated, but until there exists no integrated approach for the analysis and evaluation of complex cyber-physical systems configurations. This paper introduces integrated research infrastructure that provides methods and tools for validating smart grid systems in a holistic, cyber-physical manner. The corresponding concepts are currently being developed further in the European project ERIGrid.

description: We consider a general class of nonlinear parabolic systems corresponding to thermodynamically consistent gradient structure models of bulk-interface interaction. The setting includes non-smooth geometries and e.g. slow, fast and "entropic'' diffusion processes under mass conservation. The main results are global well-posedness and exponential stability of equilibria. As a part of the proof, we show bulk-interface maximum principles and a bulk-interface Poincaré inequality. The method of proof for global existence is a simple but very versatile combination of maximal parabolic regularity of the linearization, a priori L∞-bounds and a Schaefer's fixed point argument. This allows us to extend the setting e.g. to Allen-Cahn dissipative dynamics and to include large classes of inhomogeneous boundary conditions and external forces.

description: The focus in this dissertation was on the increasing involvement of Black male youth in the carceral system and the connection to their experiences in high school. This problem is multifaceted in education because of the numerous actors and factors that contribute to the antecedents and outcomes of the key players closest to the problem, Black males. The study was designed to address this multilayered problem by employing narratives and storytelling as tools for the intervention and interrogation of anti-Black and unwelcoming school spaces. It was intended to elevate the voices of Black males who have been involved with the court system and change the mindsets and behaviors of high school educators to foster more inclusive environments with the exploration of two imperative research questions: What factors of their high school experience influence formerly court-involved Black males (FCIBM) and their connection to school and court involvement? How does the storytelling of high school experiences from FCIBM influence high school educators’ beliefs, mindsets, and practices? The overarching theory of action was grounded in critical race theory and African American male theory research to life and confirm the vital experiences of FCIBM as a means to heighten awareness and encourage self-reflection among high school educators, empowering them to identify and implement multiculturally competent practices for Black male students. The results revealed three critical areas for educator reflection: trauma-informed teaching, focusing on students’ strengths, and implementing restorative practices. These themes are proposed as essential for future research to combat the feelings of isolation and disappointment among Black male students. The goal is for educators to become more self-aware and actively work against implicit biases using culturally relevant teaching methods that promote a sense of belonging among students. The findings advocate for the use of instructional strategies and bias awareness tools, alongside continuous professional development, to address racist beliefs, promote culturally responsive teaching, and counteract anti-Blackness in the classroom. Ultimately, this research contributes to the broader effort to dismantle White supremacist culture and address racism in educational systems.Keywords: culturally responsive teaching, disproportionality, carceral system, Black males, anti-Blackness, trauma-informed instruction, asset-based approaches, restorative practices

Cancer

description: Breast cancer, the most prevalent cancer in women globally, is characterized by a low survival rate. Euphorbia hirta is predicted to exhibit promising antibreast cancer properties. This study aimed to explore the active compounds present in the ethanol extract of E. hirta and elucidate their mechanism for countering breast cancer using computational and experimental methodologies. The active components of the E. hirta ethanol extract were determined using Liquid chromatography high-resolution mass spectrometry. Furthermore, the identified active compounds were subjected to computational analysis involving drug-likeness screening, membrane permeability, bioactivity, toxicity assessment and protein target prediction using QSAR principles followed by molecular docking and molecular dynamics simulations. In vitro experimental investigations included toxicity, rhodamine, apoptosis, cell migration and colony formation assays. These findings indicated that six compounds with drug-like properties and physicochemical features exhibited bioactivity relevant to breast cancer. These compounds, namely, quercetin, luteolin, gallic acid, gentisic acid, quinic acid and caffeic acid, target proteins associated with breast cancer progression, including EGFR, KDR, SRC, FASN, CDK4 and ERBB2. According to molecular docking and dynamics studies, these active compounds bind securely, potentially inhibiting their target protein activity. The ethanol extract of E. hirta was toxic and selective for T47D cells. The extract induced apoptosis and loss of mitochondrial membrane potential in T47D cells, restraining their migration and colony formation. The research findings demonstrate that the extract of E. hirta effectively antagonizes breast cancer by inducing apoptosis, suppressing cellular migration, and inhibiting cell colony formation through the targeted modulation of associated proteins.

description: The recent neutron-scattering data for spin-wave dispersion in $\rm Ho Mn O_3$ are well described by an anisotropic Hubbard model on a triangular lattice with a planar (XY) spin anisotropy. Best fit indicates that magnetic excitations in $\rm Ho Mn O_3$ correspond to the strong-coupling limit $U/t > \sim 15$, with planar exchange energy $J=4t^2/U \simeq 2.5$meV and planar anisotropy $ΔU \simeq 0.35$meV.
