description: Cultivated sunflower (Helianthus annuus) is the fourth most important oilseed crop globally and is known to have experienced multiple genetic bottlenecks during domestication and improvement. Homogenization of crop germplasm may limit breeding efforts to improve pest and pathogen resistance or optimize other biotic interactions like pollinator attraction. Such interactions are often strongly influenced by plant phytochemistry, especially volatile compounds like terpenoids. Here we use solid-phase microextraction gas chromatography mass spectrometry (SPME GC-MS) to evaluate volatile phytochemistry across leaves, involucral bracts, disc florets, and ray floret petals in a collection of twelve inbred lines selected to represent a cross-section of sunflower germplasm diversity. Results indicate considerable compositional diversity of volatiles among lines, though substantial reduction in total volatile abundance relative to wild H. annuus. From leaves and bracts to disc florets and petals, we observe a strong increase in the proportion of monoterpenoids relative to sesquiterpenoids accompanying the transition to reproductive structures, with consistently over 85% monoterpenoids in disc florets and petals. This pattern is driven by substantially higher production of monoterpenoids (especially alpha-pinene and sabinene) in reproductive structures. Sesquiterpenoid production is roughly similar across organs, and in leaves varies among lines from 21–55% of volatiles, dominated by cadinene-type sesquiterpenoids. This work suggests that the compositional diversity of volatile terpenoids within cultivated germplasm may be sufficient for many breeding applications, though for breeding increased volatile production the use of wild H. annuus and other wild Helianthus germplasm may be necessary.

description: There currently exist many observations which are not consistent with the cosmological principle. We review these observations with a particular emphasis on those relevant for Square Kilometre Array (SKA). In particular, several different data sets indicate a preferred direction pointing approximately towards the Virgo cluster. We also observe a hemispherical anisotropy in the Cosmic Microwave Background Radiation (CMBR) temperature fluctuations. Although these inconsistencies may be attributed to systematic effects, there remains the possibility that they indicate new physics and various theories have been proposed to explain them. One possibility, which we discuss in this review, is the generation of perturbation modes during the early pre-inflationary epoch, when the Universe may not obey the cosmological principle. Better measurements will provide better constraints on these theories. In particular, we propose measurement of the dipole in number counts, sky brightness, polarized flux and polarization orientations of radio sources. We also suggest test of alignment of linear polarizations of sources as a function of their relative separation. Finally we propose measurement of hemispherical anisotropy or equivalently dipole modulation in radio sources.

Complexity Leads to Simplicity: A Consensus Layer V Pyramidal Neuron Can Sustain Interpulse-Interval Coding

description: In terms of the long-distance communication of a single neuron, interpulse intervals (IPIs) are a possible alternative to rate and binary codes. As a proxy for IPI, the time-to-spike (TTS) for a neuron can be found in the biophysical and experimental literature. Using the current, consensus layer V pyramidal neuron, the present study examines the feasibility of IPI-coding and examines the noise sources that limit the information rate of such an encoding. In descending order of noise intensity, the noise sources are (i) synaptic variability, (ii) sodium channel shot-noise, followed by (iii) thermal noise with synaptic noise much greater than the sodium channel-noise. More importantly, the biophysical model demonstrates a linear relationship between input intensity and inverse TTS. This linear observation contradicts the assumption that a neuron should be treated as a passive, electronic circuit (an RC circuit, as in the Stein model). Finally, the biophysical simulations allow the calculation of mutual information, which is about 3.0 bits/spike.

description: The present study, investigated some reproductive and fertility parameters in some wild populations, originating from the North Tunisia (4 populations of Medicago ciliaris and 3 populations of Medicago intertexta). Previous finding revealed that these species are genetically distinct and easily recognized by the number of flowers per inflorescence and pod dimensions. However, biometrical traits and isozyme patterns intermediacy between these two species had detected the existence of a potential spontaneous interspecific hybrid originating from Sedjnane locality in Tunisia. Indeed, the present work has shown significant decrease of pollen fertility and seed production for this population when compared to the others(pollen viability 75%, pollen germinability 8% and pod production=9%). These results suggested a possible natural interspecific hybrid and confirming introgressive hybridization possibility between M. intertexta and M. ciliaris.
title: The Indentation Densification and Cracking Behavior of Fused Silica

description: The damage resistance of glass is of great scientific and economic interest. In oxide glasses crack formation is closely related to the plastic deformation processes that occur under contact stress, i.e. shear flow or structural compression. In this context an increased crack resistance is often attributed to an increased compaction capacity. However, the influence of densification on crack initiation and expansion remains unclear. In the present work the influence of densification on cracking is investigated using both cohesive zone finite element modelling and nanoindentation testing with fused silica serving as model system for densifying oxide glass. The densification information from hydrostatic compaction experiments was implemented into the FEA using modified Drucker-Prager cap plasticity. Nanoindentation experiments with various tip geometries and Raman spectroscopy were used to quantify densification and cracking experimentally. The fracture toughness of fused silica was assessed by indentation cracking and micro pillar splitting techniques, finding values in good accordance with literature.

description: Detection of individual luminous sources during the reionization epoch and cosmic dawn through their signatures in the HI 21-cm signal is one of the direct approaches to probe the epoch. Here, we summarize our previous works on this and present preliminary results on the prospects of detecting such sources using the SKA1-low experiment. We first discuss the expected HI 21-cm signal around luminous sources at different stages of reionization and cosmic dawn. We then introduce two visibility based estimators for detecting such signal: one based on the matched filtering technique and the other relies on simply combing the visibility signal from different baselines and frequency channels. We find that that the SKA1-low should be able to detect ionized bubbles of radius $R_b \gtrsim 10$ Mpc with $\sim 100$ hr of observations at redshift $z \sim 8$ provided that the mean outside neutral Hydrogen fraction $ x_{\rm HI} \gtrsim 0.5$. We also investigate the possibility of detecting HII regions around known bright QSOs such as around ULASJ1120+0641 discovered by Mortlock et al. 2011. We find that a $5 σ$ detection is possible with $600$ hr of SKA1-low observations if the QSO age and the outside $ x_{\rm HI} $ are at least $\sim 2 \times 10^7$ Myr and $\sim 0.2$ respectively. Finally, we investigate the possibility of detecting the very first X-ray and Ly-$α$ sources during the cosmic dawn. We consider mini-QSOs like sources which emits in X-ray frequency band. We find that with a total $\sim 1000$ hr of observations, SKA1-low should be able to detect those sources individually with a $\sim 9 σ$ significance at redshift $z=15$. We summarize how the SNR changes with various parameters related to the source properties.

description: Wachdienste in deutschen Bibliotheken sind keine Seltenheit mehr und scheinen sich als Partner*innen im Alltag etabliert zu haben. Doch was genau macht das Sicherheitspersonal in Bibliotheken und warum braucht es sie überhaupt? Der folgende Artikel präsentiert die Ergebnisse einer Interview-Studie, welche zum Ziel hatte herauszufinden, wie Sicherheitspersonal in den Arbeitsort Bibliothek eingebunden ist. Dazu wurden Interviews mit Personen geführt, welche in ihrer Bibliothek für den Wachschutz zuständig sind. Es stellte sich heraus, dass es zwischen den Bibliotheken Gemeinsamkeiten bezüglich der Anforderungen und Herausforderungen mit den Wachdiensten gibt, genauso aber auch unterschiedliche Herangehensweisen und bibliotheksspezifische Bedürfnisse. Diese Arbeit hatte zum einen das Ziel, eine Lücke in der aktuellen Forschung zu schliessen und zum anderen die Aufmerksamkeit auf eine Praxis zu lenken, die in deutschen Bibliotheken immer alltäglicher zu werden scheint.
description: Security guards in German libraries are no longer a rarity and seem to have established themselves as partners in the daily business. But what exactly security staff do in libraries and why do they need them at all? The following article presents the results of an interview study that aimed to find out how security staff are integrated into the library as their workplace. For this purpose, interviews were conducted with people who are responsible for security in their library. It turned out that t here are similarities between the libraries regarding the requirements and challenges with the security services, but also different approaches and library-specific needs. This work aimed on the one hand to fill a gap in current research and on the other hand to draw attention to a practice that seems to become more and more commonplace in German libraries.

description: В последние годы существенно возросло использование рапсового шрота и жмыха (они служат источником белка для сельскохозяйственных животных). Это связано с увеличением объемов производства и переработки рапса в России и обусловлено повышением стоимости соевых белковых продуктов. Продукты переработки рапса являются альтернативным сырьем для полноценного белкового кормления крупного рогатого скота и сельскохозяйственных животных. Продукты переработки семян рапса способны конкурировать с соевыми шротами различных производителей (уровень содержания сырого протеина — 38-42%, сырого жира — 1,8-10%). Его преимущество перед обычным заключается в повышенной питательности за счет высокого количества протеина с одновременно пониженным содержанием жира, что способствует лучшей перевариваемости белка.

description: We discuss applications of a recently developed method for model reduction based on linear response theory of weakly coupled dynamical systems. We apply the weak coupling method to simple stochastic differential equations with slow and fast degrees of freedom. The weak coupling model reduction method results in general in a non-Markovian system, we therefore discuss the Markovianization of the system to allow for straightforward numerical integration. We compare the applied method to the equations obtained through homogenization in the limit of large time scale separation between slow and fast degrees of freedom. We look at ensemble spread from a fixed initial condition, correlation functions and exit times from domain. The weak coupling method gives better results in all test cases, albeit with a higher numerical cost.

Исследуемая подконтрольная популяция айрширской породы включала данные по 450 головам, полученным от 11 быков зарубежной селекции и 246 головам, полученным от 11 быков отечественной селекции. Сравнительная характеристика быков-производителей показала, что дочери быков как зарубежной, так и отечественной селекции имеют примерно равные средние значения возраста первого плодотворного осеменения (17,3 и 17,9 месяца соответственно), возраста первого отела (26,4 и 27,0 месяца соответственно). Продолжительность сервис-периода на 18 дней короче у потомства быков зарубежного происхождения и составляет 126 дней, что близко к оптимальным значениям. При этом индекс осеменения дочерей быков отечественной селекции составляет 1,4, что меньше на 0,2, чем у зарубежных быков-производителей. На основании проведенных исследований можно выделить 2-х лучших быков-производителей, оцененных по комплексу воспроизводительных признаков дочерей при рейтинговом распределении: Напипер 9064929831 (Rср 2,3) зарубежной и Вулкан 1526 (Rср 1,0) отечественной селекции. Предлагаемый метод рейтинговой оценки позволяет оценить быков-производителей и провести отбор лучших из них по комплексу признаков воспроизводства дочерей.

description: Studying the cosmic dawn and the epoch of reionization through the redshifted 21 cm line are among the major science goals of the SKA1. Their significance lies in the fact that they are closely related to the very first stars in the universe. Interpreting the upcoming data would require detailed modelling of the relevant physical processes. In this article, we focus on the theoretical models of reionization that have been worked out by various groups working in India with the upcoming SKA in mind. These models include purely analytical and semi-numerical calculations as well as fully numerical radiative transfer simulations. The predictions of the 21 cm signal from these models would be useful in constraining the properties of the early galaxies using the SKA data.

description: Methyl and methylene compounds of arsenic and antimony have been studied by photoelectron photoion coincidence spectroscopy to investigate their relative stability. While for As both HAs=CH2, As−CH3 and the methylene compound As=CH2 are identified in the spectrum, the only Sb compound observed is Sb−CH3. Thus, there is a step in the main group 15 between As and Sb, regarding the relative stability of the methyl compounds. Ionisation energies, vibrational frequencies and spin-orbit splittings were determined for the methyl compound from photoion mass-selected photoelectron spectra. Although the spectroscopic results for organoantimony resemble those for the previously investigated bismuth compounds, EPR spectroscopic experiments indicate a far lower tendency for methyl transfer for Sb(CH3)3 compared to Bi(CH3)3. This study concludes investigations on low-valent organopnictogen compounds.

description: Janis-Newman-Winicour (JNW) spacetimes generalize the Schwarzschild solution to include a massless scalar field. Although suffering from naked singularities, they share the `frozen star' features of Schwarzschild black holes. Cosmological versions of the JNW spacetimes were discovered some time ago by Husain, Martinez and Nunez and by Fonarev. Unlike Schwarzschild-deSitter black holes, these solutions are dynamical, and the scarcity of exact solutions for dynamical black holes in cosmological backgrounds motivates their further study. Here we show how the cosmological JNW spacetimes can be built, starting from simpler, static, higher dimensional, vacuum `JNW brane' solutions via two different generalized dimensional reduction schemes that together cover the full range of JNW parameter space. Cosmological versions of a BPS limit of charged dilaton black holes are also known. JNW spacetimes represent a different limiting case of the charged, dilaton black hole family. We expect that understanding this second data point may be key to finding cosmological versions of general, non-BPS black holes.

Using its methyl analog [BiMe2(SbF6)] as a second reference point, the impact of steric bulk on bismuth-based Lewis acidity was investigated in a combined experimental (Gutmann-Beckett and modified Gutmann-Beckett methods) and theoretical approach (DFT calculations). Reactivity studies of the bismuth cations towards [PF6]− and neutral Lewis bases such as isocyanides C≡NR’ revealed facile fluoride ion abstraction and straightforward Lewis pair formation, respectively. The first examples of compounds featuring bismuth-bound isocyanides have been isolated and fully characterized.

description: Roth et al (2014a) reported evidence for plumes of water venting from a southern high latitude region on Europa - spectroscopic detection of off-limb line emission from the dissociation products of water. Here, we present Hubble Space Telescope (HST) direct images of Europa in the far ultraviolet (FUV) as it transited the smooth face of Jupiter, in order to measure absorption from gas or aerosols beyond the Europa limb. Out of ten observations we found three in which plume activity could be implicated. Two show statistically significant features at latitudes similar to Roth et al, and the third, at a more equatorial location. We consider potential systematic effects that might influence the statistical analysis and create artifacts, and are unable to find any that can definitively explain the features, although there are reasons to be cautious. If the apparent absorption features are real, the magnitude of implied outgassing is similar to that of the Roth et al feature, however the apparent activity appears more frequently in our data.

description: The uptake and release of small molecules continue to be challenging tasks of utmost importance in synthetic chemistry. The combination of such small molecule activation with subsequent transformations to generate unusual reactivity patterns opens up new prospects for this field of research. Here, we report the reaction of CO2 and CS2 with cationic bismuth(III) amides. CO2-uptake gives isolable, but metastable compounds, which upon release of CO2 undergo CH activation. These transformations could be transferred to the catalytic regime, which formally corresponds to a CO2-catalyzed CH activation. The CS2-insertion products are thermally stable, but undergo a highly selective reductive elimination under photochemical conditions to give benzothiazolethiones. The low-valent inorganic product of this reaction, Bi(I)OTf, could be trapped, showcasing the first example of light-induced bismuthinidene transfer.

description: The line of sight direction in the redshifted 21-cm signal coming from the cosmic dawn and the epoch of reionization is quite unique in many ways compared to any other cosmological signal. Different unique effects, such as the evolution history of the signal, non-linear peculiar velocities of the matter etc will imprint their signature along the line of sight axis of the observed signal. One of the major goals of the future SKA-LOW radio interferometer is to observe the cosmic dawn and the epoch of reionization through this 21-cm signal. It is thus important to understand how these various effects affect the signal for it's actual detection and proper interpretation. For more than one and half decades, various groups in India have been actively trying to understand and quantify the different line of sight effects that are present in this signal through analytical models and simulations. In many ways the importance of this sub-field under 21-cm cosmology have been identified, highlighted and pushed forward by the Indian community. In this article we briefly describe their contribution and implication of these effects in the context of the future surveys of the cosmic dawn and the epoch of reionization that will be conducted by the SKA-LOW.

description: Key challenges in modern synthetic chemistry include the design of reliable, selective, and more sustainable synthetic methods, as well as the development of promising candidates for new materials. Molecular bismuth compounds offer valuable opportunities as they show an intriguing spectrum of properties that is yet to be fully exploited: a soft character, a rich coordination chemistry, the availability of a broad variety of oxidation states (at least +V to −I) and formal charges (at least +3 to −3) at the Bi atoms, and reversible switching between multiple oxidation states. All this is paired with the status of a non-precious (semi−)metal of good availability and a tendency towards low toxicity. Recent findings show that some of these properties only come into reach, or can be substantially optimized, when charged compounds are specifically addressed. In this review, essential contributions to the synthesis, analyses, and utilization of ionic bismuth compounds are highlighted.

The Transdiagnostic Value of RDoC Social Processes: A Neurobehavioral Lifespan Approach
Creators: name: Palumbo, Isabella
Publisher: name: Georgia State University
Year: 2024

description:
This European-style dissertation examines the transdiagnostic utility of constructs within the National Institute for Mental Health (NIMH) Research Domain Criteria (RDoC) frameworks Social Processes domain. These four constructs  Affiliation and Attachment (AA), Social Communication (SC), Perception and Understanding of Self (PUS), and Perception and Understanding of Others (PUO)  serve as theoretical representations of the abilities to perceive, understand, respond to, and connect with others, which manifest and develop at both behavioral and neural levels. Specifically, these mechanisms support Affiliative Capacity (AFF), a dispositional, trait-like, representation of AA, that reflects individual differences in the ability to establish social-emotional bonds and relies on the availability and functionality of an array of neurobiological mechanisms (e.g., social information processing, social learning and memory, social motivation). Within the a-diagnostic RDoC framework, AFF is an early-emerging risk factor associated with multifinality across the lifespan. Moreover, empirical studies have shown that AFF is a dispositional characteristic that serves as a nexus where developmental, neurobehavioral, and clinical symptom variables intersect. Three first-author presentations demonstrate how the systematic integration of developmental perspectives, mechanistic frameworks, and dimensional models of psychopathology has both scientific and clinical value. The first two publications describe the development of indices measuring AFF in youth and adulthood and examine AFFs unique and interactive contributions to psychopathology at various levels of specificity. These studies establish the conceptual consistency of AFF across the lifespan and implicate moderators that may influence multifinality associated with AFF-related risk. The third chapter focuses on one of these putative moderators  inhibitory control  and examines the interaction with AFF to explain divergent developmental trajectories of psychopathology. The final chapter presents an overview of how the studies reviewed here fit into transdiagnostic research initiatives, with a particular emphasis on the value of considering dispositional traits within a clinical neurobehavioral context and their development across the lifespan. This chapter also includes a discussion of limitations, future directions, and the clinical utility of an integrative transdiagnostic approach, which has the potential to inform the development of targeted interventions for youth who would benefit from early intervention to reduce rates of multiple forms of psychopathology later in life.

description: We study the distributions of earthquake numbers in two global catalogs: Global Centroid-Moment Tensor and Preliminary Determinations of Epicenters. These distributions are required to develop the number test for forecasts of future seismic activity rate. A common assumption is that the numbers are described by the Poisson distribution. In contrast to the one-parameter Poisson distribution, the negative-binomial distribution (NBD) has two parameters. The second parameter characterizes the clustering or over-dispersion of a process. We investigate the dependence of parameters for both distributions on the catalog magnitude threshold and on temporal subdivision of catalog duration. We find that for most cases of interest the Poisson distribution can be rejected statistically at a high significance level in favor of the NBD. Therefore we investigate whether these distributions fit the observed distributions of seismicity. For this purpose we study upper statistical moments of earthquake numbers (skewness and kurtosis) and compare them to the theoretical values for both distributions. Empirical values for the skewness and the kurtosis increase for the smaller magnitude threshold and increase with even greater intensity for small temporal subdivision of catalogs. A calculation of the NBD skewness and kurtosis levels shows rapid increase of these upper moments levels. However, the observed catalog values of skewness and kurtosis are rising even faster. This means that for small time intervals the earthquake number distribution is even more heavy-tailed than the NBD predicts. Therefore for small time intervals we propose using empirical number distributions appropriately smoothed for testing forecasted earthquake numbers.

description: Keeping in view the ordering ambiguity that arises due to the presence of position-dependent effective mass in the kinetic energy term of the Hamiltonian, a general scheme for obtaining algebraic solutions of quantum mechanical systems with position-dependent effective mass is discussed. We quantize the Hamiltonian of the pertaining system by using symmetric ordering of the operators concerning momentum and the spatially varying mass, initially proposed by von Roos and Levy-Leblond. The algebraic method, used to obtain the solutions, is based on the concepts of supersymmetric quantum mechanics and shape invariance. In order to exemplify the general formalism a class of non-linear oscillators has been considered. This class includes the particular example of a one-dimensional oscillator with different position-dependent effective mass profiles. Explicit expressions for the eigenenergies and eigenfunctions in terms of generalized Hermite polynomials are presented. Moreover, properties of these modified Hermite polynomials, like existence of generating function and recurrence relations among the polynomials have also been studied. Furthermore, it has been shown that in the harmonic limit, all the results for the linear harmonic oscillator are recovered.

description: Computing $k$-Nearest Neighbors (KNN) is one of the core kernels used in many machine learning, data mining and scientific computing applications. Although kd-tree based $O(\log n)$ algorithms have been proposed for computing KNN, due to its inherent sequentiality, linear algorithms are being used in practice. This limits the applicability of such methods to millions of data points, with limited scalability for Big Data analytics challenges in the scientific domain. In this paper, we present parallel and highly optimized kd-tree based KNN algorithms (both construction and querying) suitable for distributed architectures. Our algorithm includes novel approaches for pruning search space and improving load balancing and partitioning among nodes and threads. Using TB-sized datasets from three science applications: astrophysics, plasma physics, and particle physics, we show that our implementation can construct kd-tree of 189 billion particles in 48 seconds on utilizing $\sim$50,000 cores. We also demonstrate computation of KNN of 19 billion queries in 12 seconds. We demonstrate almost linear speedup both for shared and distributed memory computers. Our algorithms outperforms earlier implementations by more than order of magnitude; thereby radically improving the applicability of our implementation to state-of-the-art Big Data analytics problems. In addition, we showcase performance and scalability on the recently released Intel Xeon Phi processor showing that our algorithm scales well even on massively parallel architectures.

description: The war in Ukraine has sparked an unprecedented conflict between the Russian Federation and both the United States and European Union within global networks. In this conflict, the Russians have used its hold over the energy trade to withhold natural gas imports to the European Union. The United States and European Union have used their hold over international finance to expel Russia from the SWIFT system. Instead of sending soldiers, the respective sides have sent the dollar and natural resources to do the fighting. In this thesis, I create a dynamic conceptual framework that merges network analytic conceptions of power with coercive strategy. In this framework, the strategies of both the coercer and the coerced are explained. I find that these strategies of coercion are generalizable beyond the actors associated with the war in Ukraine and that 1) states opt for offensive strategies in networks where they are the dominant power, and 2) these coercive strategies can be used both within and across multiple networks.

description: The formulation of the interaction of matter with singular light fields needs special care. In a recent article [Phys.~Rev.~A {\bf 91}, 033808 (2015)] we have shown that the Hamiltonian describing the interaction of a twisted light beam having parallel orbital and spin angular momenta with a small object located close to the phase singularity can be expressed only in terms of the electric field of the beam. Here, we complement our studies by providing an interaction Hamiltonian for beams having antiparallel orbital and spin angular momenta. Such beams may exhibit unusually strong magnetic effects. We further extend our formulation to radially and azimuthally polarized beams. The advantages of our formulation are that for all beams the Hamiltonian is written solely in terms of the electric and magnetic fields of the beam and as such it is manifestly gauge-invariant. Furthermore it is intuitive by resembling the well-known expressions in the dipole-electric and dipole-magnetic moment approximations.
