description: We construct supersymmetric $\mathrm{AdS}_4$ vacua of type IIB string theory in compactifications on orientifolds of Calabi-Yau threefold hypersurfaces. We first find explicit orientifolds and quantized fluxes for which the superpotential takes the form proposed by Kachru, Kallosh, Linde, and Trivedi. Given very mild assumptions on the numerical values of the Pfaffians, these compactifications admit vacua in which all moduli are stabilized at weak string coupling. By computing high-degree Gopakumar-Vafa invariants we give strong evidence that the $α'$ expansion is likewise well-controlled. We find extremely small cosmological constants, with magnitude $ < 10^{-123}$ in Planck units. The compactifications are large, but not exponentially so, and hence these vacua manifest hierarchical scale-separation, with the AdS length exceeding the Kaluza-Klein length by a factor of a googol.

description: Magnetic fields play an important role in almost all astrophysical phenomena including star formation. But due to the difficulty in analytic modeling and observation, magnetic fields are still poorly studied and numerical simulation has become a major tool. We have implemented a cosmological magnetohydrodynamics package for Enzo which is an AMR hydrodynamics code designed to simulate structure formation. We use the TVD solver developed by S. Li as the base solver. In addition, we employ the constrained transport(CT) algorithm as described by D. Balsara. For interpolation magnetic fields to fine grids we used a divergence free quadratic reconstruction, also described by Balsara. We present results from several test problems including MHD caustics, MHD pancake and galaxy cluster formation with magnetic fields. We also discuss possible applications of our AMR MHD code to first star research.

description: The near-threshold $e^+e^- \to Λ\barΛ$ reaction is studied with the assumption that the production mechanism is due to a near-$Λ\barΛ$-threshold bound state. The cross section of $e^+e^- \to Λ\barΛ$ reaction is parametrized in terms of the electromagnetic form factors of $Λ$ hyperon, which are obtained with the vector meson dominance model. It is shown that the contribution to the $e^+e^- \to Λ\barΛ$ reaction from a new narrow state with quantum numbers $J^{PC}=1^{--}$ is dominant for energies very close to threshold. The mass of this new state is around 2231 MeV, which is very close to the mass threshold of $Λ\barΛ$, while its width is just a few MeV. This gives a possible solution to the problem that all previous calculations seriously underestimate the near-threshold total cross section of the $e^+e^- \to Λ\barΛ$ reaction. We also note that the near-threshold enhancement can be also reproduced by including these well established vector resonances $ω(1420)$, $ω(1650)$, $ϕ(1680)$, or $ϕ(2170)$ with a Flatt${\rm\acute{e}}$ form for their total decay width, and a strong coupling to the $Λ\barΛ$ channel.

Determining cerebral lateralisation : the use of the P300
Creators: name: Harpur, Timothy John
Publisher: name: University of British Columbia
Year: 2010

description: The P300 component of the average evoked potential was recorded at Pz during two divided visual field tasks. During a lexical decision task, reaction time and P300 latency were faster to stimuli in the right visual field, indicating that the latency of the P300 may be a useful measure in laterality research. A right visual field advantage was obtained for reaction time in a face perception task and the P300 latency difference showed a similar but non-significant advantage. Use of the P300 latency to assess the validity of the assumptions underlying the application of an additive factors model to divided visual field studies of cerebral assymetry was discussed. The present evidence suggests that the assumptions are valid.

description: Building-change detection underpins many important applications, especially in the military and crisis-management domains. Recent methods used for change detection have shifted towards deep learning, which depends on the quality of its training data. The assembly of large-scale annotated satellite imagery datasets is therefore essential for global building-change surveillance. Existing datasets almost exclusively offer near-nadir viewing angles. This limits the range of changes that can be detected. By offering larger observation ranges, the scroll imaging mode of optical satellites presents an opportunity to overcome this restriction. This paper therefore introduces S2Looking, a building-change-detection dataset that contains large-scale side-looking satellite images captured at various off-nadir angles. The dataset consists of 5000 bitemporal image pairs of rural areas and more than 65,920 annotated instances of changes throughout the world. The dataset can be used to train deep-learning-based change-detection algorithms. It expands upon existing datasets by providing (1) larger viewing angles; (2) large illumination variances; and (3) the added complexity of rural images. To facilitate {the} use of the dataset, a benchmark task has been established, and preliminary tests suggest that deep-learning algorithms find the dataset significantly more challenging than the closest-competing near-nadir dataset, LEVIR-CD+. S2Looking may therefore promote important advances in existing building-change-detection algorithms. The dataset is available at https://github.com/S2Looking/.
Revisiting the one-dimensional diffusive contact process

description: In this work we study the one-dimensional contact process with diffusion using two different approaches to research the critical properties of this model: the supercritical series expansions and finite-size exact solutions. With special emphasis we look to the multicritical point and its crossover exponent that characterizes the passage between DP and mean-field critical properties. This crossover occurs in the limit of infinite diffusion rate and our results pointed $ϕ=4$ as the better estimate for the crossover exponent in agreement with computational simulations.

description: Ideas in literature are immersed into a huge mass of non-conceptual discourses; take very often a metaphoric form; they are in many texts entrusted to fictional persons, to imaginary characters; they have a specific, and even paradoxical, form of responsibility. These features of ideas in literature, making them a privileged object of study in intellectual history, are exemplified by Théophile Gautier’s novel Mademoiselle de Maupin, more precisely by its preface, considered to be a manifesto of Art for Art’s Sake doctrine.

description: Enabling compilers to automatically optimize code has been a longstanding goal for the compiler community. Efficiently solving this problem requires using precise cost models. These models predict whether applying a sequence of code transformations reduces the execution time of the program. Building an analytical cost model to do so is hard in modern x86 architectures due to the complexity of the microarchitecture. In this paper, we present a novel deep learning based cost model for automatic code optimization. This model was integrated in a search method and implemented in the Tiramisu compiler to select the best code transformations. The input of the proposed model is a set of simple features representing the unoptimized code and a sequence of code transformations. The model predicts the speedup expected when the code transformations are applied. Unlike previous models, the proposed one works on full programs and does not rely on any heavy feature engineering. The proposed model has only 16% of mean absolute percentage error in predicting speedups on full programs. The proposed model enables Tiramisu to automatically find code transformations that match or are better than state-of-the-art compilers without requiring the same level of heavy feature engineering required by those compilers.

description: More than 60,000 images of Mercury were taken at ~29 deg elevation during two sunrises, at 820 nm, and through a 1.35 m diameter off-axis aperture on the SOAR telescope. The sharpest resolve 0.2" (140 km) and cover 190-300 deg longitude -- a swath unseen by the Mariner 10 spacecraft -- at complementary phase angles to previous ground-based optical imagery. Our view is comparable to that of the Moon through weak binoculars. Evident are the large crater Mozart shadowed on the terminator, fresh rayed craters, and other albedo features keyed to topography and radar reflectivity, including the putative huge ``Basin S'' on the limb. Classical bright feature Liguria resolves across the northwest boundary of the Caloris basin into a bright splotch centered on a sharp, 20 km diameter radar crater, and is the brightest feature within a prominent darker ``cap'' (Hermean feature Solitudo Phoenicis) that covers the northern hemisphere between longitudes 140-250 deg. The cap may result from space weathering that darkens via a magnetically enhanced flux of the solar wind, or that reddens low latitudes via high solar insolation.

title: Effect of Fluoride on Respiratory Enzymes in Soybean Leaves
Creators: name: Lee, Arthur Chiu-Eng
Publisher: name: Utah State University
Year: 1965

description: There are many reports relating the effects of fluorides on plant respiration. Fluoride has been regarded as an inhibitor of respiration. Warburg et al. (1942) demonstrated that fluoride inhibited enolase activity, therefore, decreased the respiration rate of yeast, Miller (1958), found a similar inhibition of enolase from pea seed. Bonner (1948), Bonner and Wildman (1946), and Laties (1949) reported that the fluoride ion in culture solutions reduced the respiration rate in Avena Coleoptile, spinach leaves and barley roots. Since the inhibition was reversed by the addition of pyruvate, they concluded that the inhibition of respiration was due to the inactivation of fluoride sensitive enolase. Chung and Nickerson (1954) studied yeast cells grown in presence of fluoride and concluded that the inhibition of growth was due to the inhibition of polysaccharide synthesis, and the site of inhibition was the enzyme phosphoglucomutase. Yang and Miller (1963) found divergent sucrose, reducing sugar contents in fluoride fumigated soybean leaves and concluded that the enzyme phophoglucomutase was the site of fluoride inhibition in sucrose synthesis. Phosphorylase (Rapp and Sliwinski, 1956), phosphatase (Lammer and Hafer, 1953; Pierpoint, 1957) and hexokinase (Melchior and Melchior, 1956) have also been reported to be fluoride sensitive in vitro.
title: An Electron Microscopic Examination of Spermiogenesis in the Recessive Sex-Linked Male-Sterile Mutant, ms(1)10S of Drosophila melanogaster
Creators: name: Perkins, Lizabeth A.
Publisher: name: Utah State University
Year: 1979

description: Electron microscopy of the testes of mutant ms(1)10S of Drosophila melanogaster is characterized by three major defects in the tail region of the developing spermatid. One is the apparent lack of paracrystalline body formation. The second is the loss of the primary derivative as development proceeds, and the third is the breakup and incorporation of the plasma membrane and periaxonemal sheath into membranous whorls. The mutant shows different patterns of axonemal breakup depending on the stage of differentiation in which degeneration begins. Degeneration continues until only cellular debris, scattered axonemal profiles and membranous whorls are all that are seen in the basal end of the testis. Randomly distributed, longitudinally oriented microtubules are also observed in the cyst cells surrounding spermatid bundles. The analysis of this mutant has elucidated the importance of the primary derivative to the developing spermatid and the requirement for a paracrystalline body for normal development. It further shows that the integrity of the axonemal components increases as spermatid development proceeds.

title: In Vitro Morphogenesis and Mutation of Glycine max L.
Creators: name: WIlson, Thomas Daniel
Publisher: name: Utah State University
Year: 1977

description: Soybean (Glycine max L. c.v. Consoy) tissue cultures were grown in synthetic media containing various concentrations and combinations of minerals, auxins, cytokinins, pH levels, and inorganic growth factors in a systematic procedure to establish optimum media for initiation and maintenance of callus. Further modification of the hormone level was employed to initiate callus morphogenesis. Normally toxic levels of atrazine were established in soybean calli media, and ethyl methanesulfonate (EMS) and X ray-induced mutant calli were selected for atrazine tolerance.
Optimal media for initiation and maintenance of soybean calli were developed and a defined medium was determined that consistently yields root differentiation in nearly 25% of the trials. Atrazine concentrations of 8 mg/l or greater in the medium resulted in 100% fatality of soybean calli; however, approximately 2% of calli treated with X rays or EMS demonstrated resistance to atrazine at a concentration of 20 mg/l. The implications and potential uses of these developments are discussed.

description: Improving three-dimensional (3D) localization precision is of paramount importance for super-resolution imaging. By properly engineering the point spread function (PSF), such as utilizing Laguerre-Gaussian (LG) modes and their superposition, the ultimate limits of 3D localization precision can be enhanced. However, achieving these limits is challenging, as it often involves complicated detection strategies and practical limitations. In this work, we rigorously derive the ultimate 3D localization limits of LG modes and their superposition, specifically rotation modes, in the multi-parameter estimation framework. Our findings reveal that a significant portion of the information required for achieving 3D super-localization of LG modes can be obtained through feasible intensity detection. Moreover, the 3D ultimate precision can be achieved when the azimuthal index $l$ is zero. To provide a proof-of-principle demonstration, we develop an iterative maximum likelihood estimation (MLE) algorithm that converges to the 3D position of a point source, considering the pixelation and detector noise. The experimental implementation exhibits an improvement of up to two-fold in lateral localization precision and up to twenty-fold in axial localization precision when using LG modes compared to Gaussian mode. We also showcase the superior axial localization capability of the rotation mode within the near-focus region, effectively overcoming the limitations encountered by single LG modes. Notably, in the presence of realistic aberration, the algorithm robustly achieves the Cramér-Rao lower bound. Our findings provide valuable insights for evaluating and optimizing the achievable 3D localization precision, which will facilitate the advancements in super-resolution microscopy.

description: Artificial intelligence (AI) applications to support human tutoring have potential to significantly improve learning outcomes, but engagement issues persist, especially among students from low-income backgrounds. We introduce an AI-assisted tutoring model that combines human and AI tutoring and hypothesize that this synergy will have positive impacts on learning processes. To investigate this hypothesis, we conduct a three-study quasi-experiment across three urban and low-income middle schools: 1) 125 students in a Pennsylvania school; 2) 385 students (50% Latinx) in a California school; and 3) 75 students (100% Black) in a Pennsylvania charter school, all implementing analogous tutoring models. We compare learning analytics of students engaged in human-AI tutoring compared to students using math software only. We find human-AI tutoring has positive effects, particularly in student's proficiency and usage, with evidence suggesting lower achieving students may benefit more compared to higher achieving students. We illustrate the use of quasi-experimental methods adapted to the particulars of different schools and data-availability contexts so as to achieve the rapid data-driven iteration needed to guide an inspired creation into effective innovation. Future work focuses on improving the tutor dashboard and optimizing tutor-student ratios, while maintaining annual costs per students of approximately $700 annually.

description: The understanding of depletion layers is of major importance to control the optical and electronic properties of metal oxide (MO) nanocrystals (NCs). Here, we show that depletion layer engineering is the main mechanism of photodoping of MO NCs. We show that the introduction of different electronic interfaces induces a double-bending of the electronic bands and a distinct carrier density profile. We found that the light-induced depletion layer modulation and bending of the bands close to the surface of the nanocrystal is the main mechanism responsible for the storage of extra electrons after photodoping in MO NCs. We support our results by a combined experimental and theoretical approach in the case of Sn:In2O3/In2O3 core-shell NCs, in which we compare numerical simulations with empirical modeling and experiments. This allows not only to extract the main mechanism of photodoping in MO NCs but also to engineer the charge storage capability of MO NCs after photodoping. Our results are transferable to other core-multishell systems, opening up a novel direction to control the optoelectronic properties of nanoscale MOs by designing their energetic band profiles through depletion layer engineering.

title: Modification of Ontogenic Expression Due to Relocation of the ry+ Gene in Drosophila melanogaster
Creators: name: Badgett, Allen A.
Publisher: name: Utah State University
Year: 1973

description: The ry+ gene of Drosophila melanogaster and its associated enzyme, xanthine dehydrogenase, were employed in an analysis of the relationship between regulation and the location of a gene in the genome. Enzyme assays as an indication of gene activity were performed on genotypes containing zero, one and two doses of ry+ genes. Xanthine dehydrogenase activity of rosy genes in normal and relocated positions was determined during development.
The results indicate: 1) the gene ry+ is differentially active during ontogeny; 2) the activity during ontogeny is proportional to the number of ry+ genes present in the genome; and 3) a unique level of xanthine dehydrogenase activity is associated with relocated ry+ genes in the absence of a structurally normal third chromosome.
Genotypes containing relocated ry+ genes have a similar developmental curve of enzyme activity as that of the control. The genotypes with a relocated ry+ gene and lacking a structurally normal third chromosome consistently have a higher level of enzyme activity than the control, except in the late pupal stage. This increased level of activity is not the result of a general physiological effect since the ontogenic profile of glucose-6-phosphate dehydrogenase activity is the same in wild type and relocated ry+ genotypes. The relevance of the data to models for gene regulation is discussed.
Graph-Based Generalization of Galam Model: Convergence Time and Influential Nodes

description: We study a graph-based generalization of the Galam opinion formation model. Consider a simple connected graph which represents a social network. Each node in the graph is colored either blue or white, which indicates a positive or negative opinion on a new product or a topic. In each discrete-time round, all nodes are assigned randomly to groups of different sizes, where the node(s) in each group form a clique in the underlying graph. All the nodes simultaneously update their color to the majority color in their group. If there is a tie, each node in the group chooses one of the two colors uniformly at random. Investigating the convergence time of the model, our experiments show that the convergence time is a logarithm function of the number of nodes for a complete graph and a quadratic function for a cycle graph. We also study the various strategies for selecting a set of seed nodes to maximize the final cascade of one of the two colors, motivated by viral marketing. We consider the algorithms where the seed nodes are selected based on the graph structure (nodes' centrality measures such as degree, betweenness, and closeness) and the individual's characteristics (activeness and stubbornness). We provide a comparison of such strategies by conducting experiments on different real-world and synthetic networks.

description: We show how a relativistic Langevin equation can be derived from a Lorentz-covariant version of the Caldeira-Leggett particle-bath Lagrangian. In one of its limits, we identify the obtained equation with the Langevin equation used in contemporary extensions of statistical mechanics to the near-light-speed motion of a Brownian particle in non-relativistic dissipative fluids. The proposed framework provides a more rigorous and first-principles form of the Langevin equation often quoted or postulated as ansatz in previous works. We then refine the aforementioned results by considering more terms in the particle-bath coupling, which improves the precision of the approximation for fully relativistic settings where not only the tagged particle but also the thermal bath motion is relativistic. We discuss the implications of the apparent breaking of space-time translation and parity invariance, showing that these effects are not necessarily in contradiction with the assumptions of statistical mechanics. The intrinsically non-Markovian character of the fully relativistic generalized Langevin equation derived here, and of the associated fluctuation-dissipation theorem, is also discussed.

description: The advent of Industrial Internet of Things (IIoT) has imposed more stringent requirements on industrial software in terms of communication delay, scalability, and maintainability. Microservice architecture (MSA), a novel software architecture that has emerged from cloud computing and DevOps, presents itself as the most promising solution due to its independently deployable and loosely coupled nature. Currently, practitioners are inclined to migrate industrial legacy systems to MSA, despite numerous challenges it presents. In this paper, we propose an automated microservice decomposition method for extracting microservice candidates based on spectral graph theory to address the problems associated with manual extraction, which is time-consuming, labor intensive, and highly subjective. The method is divided into three steps. Firstly, static and dynamic analysis tools are employed to extract dependency information of the legacy system. Subsequently, information is transformed into a graph structure that captures inter-class structure and performance relationships in legacy systems. Finally, graph-based clustering algorithm is utilized to identify potential microservice candidates that conform to the principles of high cohesion and low coupling. Comparative experiments with state of-the-art methods demonstrate the significant advantages of our proposed method in terms of performance metrics. Moreover, Practice show that our method can yield favorable results even without the involvement of domain experts.

description: Time-delayed feedback methods can be used to control unstable periodic orbits as well as unstable steady states. We present an application of extended time delay autosynchronization introduced by Socolar et al. to an unstable focus. This system represents a generic model of an unstable steady state which can be found for instance in a Hopf bifurcation. In addition to the original controller design, we investigate effects of control loop latency and a bandpass filter on the domain of control. Furthermore, we consider coupling of the control force to the system via a rotational coupling matrix parametrized by a variable phase. We present an analysis of the domain of control and support our results by numerical calculations.

The mutations were induced on the third chromosome with the monoalkylating agent ethyl methanesulfonate and were maintained in stock cultures over a balancer chromosome using a system of multiple inversions. The stages of sperm differentiation, a most dramatic form of cellular differentiation, were then studied at the electron microscope level to determine the effect of the mutations on sperm structure and to correlate those changes with normal sperm development.
Studies of the genetic control of cellular differentiation have been hampered by difficulties in devising an in vitro system. Drosophila melanogaster provides an excellent system for these types of studies since the genome is well characterized, sperm development is a continual process, it is a higher organism with many complex interactions and normal sperm differentiation has been well characterized and can serve as the control over such genetic manipulations.
Analysis of the first of the two mutants studied, ms(3)10R, presents some evidence for an inductive action of cytoplasmic microtubules on the condensation of chromatin in the nuclei of developing sperm which, in turn, influences the normal differentiation and shaping of the sperm head. Additionally, the study of this mutant appears to indicate that this locus exercises an organizational rather than a structural control.
The second mutant studied, ms(3)3R, shows normal sperm differentiation until a very late stage of development. The sperm tails then proceed to degenerate in an ordered fashion that differs from the degenerative changes to the sperm tails described for Y-chromosome mutations and deficiencies. In addition to the ultrastructural changes seen, the male-sterile flies fail to copulate. It appears, therefore, that this genetic locus on the third chromosome functions in the maintenance of sperm structure and also the normal behavior of the flies. The behavioral abnormality observed suggests that the mutation affects the normal endocrine system of Drosophila melanogaster.

description: We have investigated the magnetic properties of a piezoelectric actuator/ferromagnetic semiconductor hybrid structure. Using a GaMnAs epilayer as the ferromagnetic semiconductor and applying the piezo-stress along its [110] direction, we quantify the magnetic anisotropy as a function of the voltage V_p applied to the piezoelectric actuator using anisotropic magnetoresistance techniques. We find that the easy axis of the strain-induced uniaxial magnetic anisotropy contribution can be inverted from the [110] to the [1-10] direction via the application of appropriate voltages V_p. At T=5K the magnetoelastic term is a minor contribution to the magnetic anisotropy. Nevertheless, we show that the switching fields of rho(H) loops are shifted as a function of V_p at this temperature. At 50K - where the magnetoelastic term dominates the magnetic anisotropy - we are able to tune the magnetization orientation by about 70 degree solely by means of the electrical voltage V_p applied. Furthermore, we derive the magnetostrictive constant lambda_111 as a function of temperature and find values consistent with earlier results. We argue that the piezo-voltage control of magnetization orientation is directly transferable to other ferromagnetic/piezoelectric hybrid structures, paving the way to innovative multifunctional device concepts. As an example, we demonstrate piezo-voltage induced irreversible magnetization switching at T=40K, which constitutes the basic principle of a nonvolatile memory element.

description: The space-borne gravitational wave (GW) detectors, LISA and TAIJI, are planned to be launched in the 2030s. The dual detectors with comparable sensitivities will form a network observing GW with significant advantages. In this work, we investigate the three possible LISA-TAIJI networks for the different location and orientation compositions of LISA orbit ($+60^\circ$ inclination and trailing the Earth by $20^\circ$) and alternative TAIJI orbit configurations including TAIJIp ($+60^\circ$ inclination and leading the Earth by $20^\circ$), TAIJIc ($+60^\circ$ inclination and co-located with LISA), TAIJIm ($-60^\circ$ inclination and leading the Earth by $20^\circ$). In the three LISA-TAIJI configurations, the LISA-TAIJIm network shows the best performance on the sky localization and polarization determination for the massive binary system due to their better complementary antenna pattern, and LISA-TAIJIc could achieve the best cross-correlation and observe the stochastic GW background with an optimal sensitivity.

title: Carbon, Nitrogen and Algal Biomass in Cold Desert Soil Crusts
Creators: name: Vogelsberg, Mary Cleave
Publisher: name: Utah State University
Year: 1975

description: The algal biomass, total organic carbon, total nitrogen and percent soil moisture of soil crusts for a ten month period are presented for the Curlew Valley region of northern Utah. The estimates establish a significant relationship among these parameters.
A method involving chlorophyll extraction to determine the biomass of soil algae has been developed, and from this method the following conclusions are suggested: the revegetation of soil surfaces by algal crusts after lethal treatment, without physical disruption, appears to be rapid; there is no apparent relationship between the amount of algal biomass and the type of vascular vegetation present.

description: Machine Learning (ML) techniques are becoming an invaluable support for network intrusion detection, especially in revealing anomalous flows, which often hide cyber-threats. Typically, ML algorithms are exploited to classify/recognize data traffic on the basis of statistical features such as inter-arrival times, packets length distribution, mean number of flows, etc. Dealing with the vast diversity and number of features that typically characterize data traffic is a hard problem. This results in the following issues: i) the presence of so many features leads to lengthy training processes (particularly when features are highly correlated), while prediction accuracy does not proportionally improve; ii) some of the features may introduce bias during the classification process, particularly those that have scarce relation with the data traffic to be classified. To this end, by reducing the feature space and retaining only the most significant features, Feature Selection (FS) becomes a crucial pre-processing step in network management and, specifically, for the purposes of network intrusion detection. In this review paper, we complement other surveys in multiple ways: i) evaluating more recent datasets (updated w.r.t. obsolete KDD 99) by means of a designed-from-scratch Python-based procedure; ii) providing a synopsis of most credited FS approaches in the field of intrusion detection, including Multi-Objective Evolutionary techniques; iii) assessing various experimental analyses such as feature correlation, time complexity, and performance. Our comparisons offer useful guidelines to network/security managers who are considering the incorporation of ML concepts into network intrusion detection, where trade-offs between performance and resource consumption are crucial.
