description: The possibility to tailor photoluminescence (PL) of monolayer transition metal dichalcogenides (TMDCs) using external factors such as strain, doping and external environment is of significant interest for optoelectronic applications. Strain in particular can be exploited as a means to continuously vary the bandgap. Micrometer-scale strain gradients were proposed for creating 'artificial atoms' that can utilize the so-called exciton funneling effect and work, for example, as exciton condensers. Here we describe room-temperature PL emitters that naturally occur whenever monolayer TMDC is deposited on an atomically flat substrate. These are hydrocarbon-filled bubbles which provide predictable, localized PL from well-separated submicron areas. Their emission energy is determined by the built-in strain controlled only by the substrate material, such that both the maximum strain and the strain profile are universal for all bubbles on a given substrate, i.e., independent of the bubble size. We show that for bubbles formed by monolayer MoS2, PL can be tuned between 1.72 to 1.81 eV by choosing bulk PtSe2, WS2, MoS2 or graphite as a substrate and its intensity is strongly enhanced by the funneling effect. Strong substrate-dependent quenching of the PL in areas of good contact between MoS2 and the substrate ensures localization of the luminescence to bubbles only; by employing optical reflectivity measurements we identify the mechanisms responsible for the quenching. Given the variety of available monolayer TMDCs and atomically flat substrates and the ease of creating such bubbles, our findings open a venue for making and studying the discussed light-emitting 'artificial atoms' that could be used in applications.

description: The ground state phase diagram of 2D electrons in a high Landau level (index N=2) is studied by the density matrix renormalization group method. Pair correlation functions are systematically calculated for various filling factors from v=1/8 to 1/2. It is shown that the ground state phase diagram consists of three different CDW states called stripe-phase, bubble-phase, and Wigner crystal. The boundary between the stripe and the bubble phases is determined to be v_c = 0.38, and that for the bubble phase and Wigner crystal is v_c = 0.24. Each transition is of first order.

description: We develop a scaling theory to describe dynamic fluctuations of a semiflexible polymer and find several distinct regimes. We performed simulations to characterize the longitudinal and transverse dynamics; using ensemble averaging for a range of different degrees of coarse-graining we avoid the problems of slow equilibration often encountered in simulations. We find that the longitudinal fluctuations of a semiflexible object scales as t^7/8. These fluctuations are correlated over a length which varies as t^1/8. Our results are pertinent to the interpretation of high frequency microrheology experiments in actin solutions.

By explicitly working out a case study where the singlet insulator is stabilized by orbital degeneracy and an inverted Hund's rule coupling, mimicking a Jahn-Teller effect, we find that the intermediate phase is a superconductor.

description: The magnetic susceptibilities chi versus temperature T of powders and single crystals of the ambient-pressure (AP) and high-pressure (HP) phases of (VO)_{2}P_{2}O_{7} are analyzed using an accurate theoretical prediction of chi(T, J1, J2) for the spin-1/2 antiferromagnetic alternating-exchange (J1, J2) Heisenberg chain. The results are consistent with recent models with two distinct types of alternating-exchange chains in the AP phase and a single type in the HP phase. The spin gap for each type of chain is derived from the respective set of two fitted alternating exchange constants and the one-magnon dispersion relation for each of the two types of chains in the AP phase is predicted. The influences of interchain coupling on the derived intrachain exchange constants, spin gaps, and dispersion relations are estimated using a mean-field approximation for the interchain coupling. The accuracies of the spin gaps obtained using fits to the low-T chi(T) data by theoretical low-T approximations are determined. The results of these studies are compared with previously reported estimates of the exchange couplings and spin gaps in the AP and HP phases and with the magnon dispersion relations in the AP phase measured previously using inelastic neutron scattering.

description: Active Galactic Nuclei are considered as sources of neutrinos, with neutrino energies extending up to 10^{18} eV. It is expected that these highly energetic cosmic neutrinos will be detected by the neutrino telescopes, presently under construction. The detection process is very sensitive to the total muon neutrino cross-section. We examine how the total cross section changes at high energies, by the single production of excited fermions (excited muon and muon-neutrino). For parameters (masses, couplings) of the excited fermions allowed by the experimental constraints, we find that for energies of the incoming muon-neutrino above 100 TeV the cross-section for single production of (excited muon and muon-neutrino) supersedes the standard total cross-section.

description: We study the pre-K-edge structure of the resonant X-ray scattering for forbidden reflections (anomalous scattering) in LaMnO3, using the band calculation based on the local density approximation. We find a two-peak structure with an intensity approximately 1/100 of that of the main peak. This originates from a mixing of 4p states of Mn to 3d states of neighboring Mn sites. The effect is enhanced by an interference with the tail of the main peak. The effect of the quadrupole transition is found to be one order of magnitude smaller than that of the dipole transition, modifying slightly the azimuthal-angle dependence.

description: Experience plays a critical role in crafting high impact scientific work. This is particularly evident in top multidisciplinary journals, where a scientist is unlikely to appear as senior author if they have not previously published within the same journal. Here, we develop a quantitative understanding of author order by quantifying this 'Chaperone Effect', capturing how scientists transition into senior status within a particular publication venue. We illustrate that the chaperone effect has different magnitude for journals in different branches of science, being more pronounced in medical and biological sciences and weaker in natural sciences. Finally, we show that in the case of high-impact venues, the chaperone effect has significant implications, specifically resulting in a higher average impact relative to papers authored by new PIs. Our findings shed light on the role played by experience in publishing within specific scientific journals, on the paths towards acquiring the necessary experience and expertise, and on the skills required to publish in prestigious venues.

description: The quantum ANNNI chain in a transverse field is investigated by means of the bosonization approach in the limit of large next-nearest neighbor interaction. In this regime, this model can be viewed as a weakly coupled two-leg zigzag ladder which enables us to derive its low energy effective field theory. In particular, it is shown that the effect of frustration in the system is captured by the presence of a non zero conformal spin perturbation that accounts for the existence of all the incommensurate phases of the model.

description: The temperature dependence of the hydrodynamic boundary condition between a PDMS melt and two different non-attractive surfaces made of either an OTS (octadecyltrichlorosilane) self-assembled monolayer (SAM) or a grafted layer of short PDMS chains has been characterized. A slip length proportional to the fluid viscosity is observed on both surfaces. The slip temperature dependence is deeply influenced by the surfaces. The viscous stress exerted by the polymer liquid on the surface is observed to follow exactly the same temperature dependences as the friction stress of a cross-linked elastomer sliding on the same surfaces. Far above the glass transition temperature, these observations are rationalized in the framework of a molecular model based on activation energies: increase or decrease of the slip length with increasing temperatures can be observed depending on how the activation energy of the bulk viscosity compares to that of the interfacial Navier's friction coefficient.

description: The agreement in mammographic lesion features from two projections of the breast was studied for human extracted BI-RADS" and computer extracted image texture features and cases with low agreement were identified. Factors affecting agreement between the two views were isolated and agreement for the two types of features was compared. Agreement in BI-RADS" features was higher than that for texture features, however agreement for both types of features was affected by the institutional source of data. Statistical classifiers for distinguishing benign from malignant lesions were designed using BI-RADS" features from multiple views and the effect of including patient age was investigated. The highest AUC ± SD value of 0.927 ± 0.026 was obtained for a classifier that used features from both the MLO and CC views as well as patient age as features.

description: Using Kohn-Sham wave functions and their energy levels obtained by density-functional-theory total-energy calculations, the electronic structure of the two c(2x2) phases of Na on Al(001) are analysed; namely, the metastable hollow-site structure formed when adsorption takes place at low temperature, and the stable substitutional structure appearing when the substrate is heated thereafter above ca. 180K or when adsorption takes place at room temperature from the beginning. The experimentally obtained two-dimensional band structures of the surface states or resonances are well reproduced by the calculations. With the help of charge density maps it is found that in both phases, two pronounced bands appear as the result of a characteristic coupling between the valence-state band of a free c(2x2)-Na monolayer and the surface-state/resonance band of the Al surfaces; that is, the clean (001) surface for the metastable phase and the unstable, reconstructed "vacancy" structure for the stable phase. The higher-lying band, being Na-derived, remains metallic for the unstable phase, whereas it lies completely above the Fermi level for the stable phase, leading to the formation of a surface-state/resonance band-structure resembling the bulk band-structure of an ionic crystal.

description: In quantum critical heavy fermion systems, local moments are coupled to both collective spin fluctuations and conduction electrons. As such, the Bose-Fermi Kondo model, describing the coupling of a local moment to both a bosonic and a fermionic bath, has been of extensive interest. For the model in the presence of SU(2) spin rotational symmetry, questions have been raised about its phase diagram. Here we develop a version of continuous-time Quantum Monte Carlo (CT-QMC) method suitable for addressing this issue; this procedure can reach sufficiently low temperatures while preserving the SU(2) symmetry. Using this method for the Bose-Fermi Anderson model, we clarify the renormalization-group fixed points and the phase diagram for the case with a constant fermionic-bath density of states and a power-law bosonic-bath spectral function $ρ_{b}(ω) \propto ω^{s}$ ($0

description: Much literature on the disaster-culture nexus focuses on tangible elements such as demograpics or geography and adopts an anthropocentric Western and positivistic mindset. In contrast, this Working Paper applies an epistemological ‘disaster*cultures’ approach to Indonesia. We put the onus on construction processes, interpreting and finding meaning rather than on identifying set patterns, and highlight how culture does not refer to ‘exotic’ processes that can only be studied at the community level. Researchers, practitioners and policy-makers all approach disasters and risks through their own specific (disciplinary) lenses. The first part of thiw Working Paper will introduce our disaster*cultures-approach. Subsequently, analysing academic literature in English and Bahasa Indonesia, but also poems, art, toponyms, grey literature and selected exchanges conducted with Indonesian tsunami scientists and disaster management officials in 2022 as part of the TSUNAMI_RISK research project, we review the socio-historical ways through which multi-ple disaster*cultures have formed in Indonesia. The remainder of the Working Paper details the main disaster stakeholders, policies and practices at play in Indonesia today, particularly in re-gard to the Indonesian Tsunami Warning System (InaTEWS) and efforts to detect non-seismically induced tsunamis. As such, we aim to provide disaster scholars and practitioners with a holistic overview of the Indonesian contexts in which they operate, and to facilitate more socio-culturally sensitive technology and warning system development.
Oblique instability and electron acceleration in relativistic unmagnetized cloud-plasma interaction

description: Relativistic unmagnetized cloud-plasma interaction is analyzed by performing linear analysis and particle-in-cell simulation. This course consists of an electron-ion cloud injected into a stationary ambient plasma and has long been a favorite topic in laboratory and space plasmas. An oblique electromagnetic instability dominates the unstable spectrum. In the interaction with the generated electromagnetic fields, the cloud electrons are entirely mixed with the ambient ones and form a hot electron population. The velocity of the cloud ions, however, has not changed significantly from the initial bulk velocity. As this ion cloud propagates into the plasma, it derives an electrostatic field which can accelerate the electrons up to energy equipartition between electrons and ions. The electrostatic field is amplified at the expense of the kinetic energy of ions, and its spatial scale is in order of the electron skin depth. The electron acceleration in such an electrostatic field is, therefore, a likely process for pre-acceleration of electrons in unmagnetized plasmas.

description: Starting from Buchmüller's observation that a chromoelectric flux tube meson will exhibit only the Thomas type spin-orbit interaction, we show that a model built upon the related assumption that a quark feels only a constant radial chromoelectric field in its rest frame implies a complete relativistic effective Hamiltonian that can be written explicitly in terms of quark canonical variables. The model yields linear Regge trajectories and exhibits some similarities to scalar confinement, but with the advantage of being more closely linked to QCD.

description: T cell receptor (TCR) repertoire sequencing has emerged as a powerful tool for understanding the diversity and functionality of T cells within the host immune system. Yet, the chicken TCR repertoire remains poorly understood due to incomplete genome annotation of the TCR loci, despite the importance of chickens in agriculture and as an immunological model. Here, we addressed this critical issue by employing 5’ rapid amplification of complementary DNA ends (5’RACE) TCR repertoire sequencing with molecular barcoding of complementary DNA (cDNA) molecules. Simultaneously, we enhanced the genome annotation of TCR Variable (V), Diversity (D, only present in β and δ loci) and Joining (J) genes in the chicken genome. To enhance the efficiency of TCR annotations, we developed VJ-gene-finder, an algorithm designed to extract VJ gene candidates from deoxyribonucleic acid (DNA) sequences. Using this tool, we achieved a comprehensive annotation of all known chicken TCR loci, including the α/δ locus on chromosome 27. Evolutionary analysis revealed that each locus evolved separately by duplication of long homology units. To define the baseline TCR diversity in healthy chickens and to demonstrate the feasibility of the approach, we characterized the splenic α/β/γ/δ TCR repertoire. Analysis of the repertoires revealed preferential usage of specific V and J combinations in all chains, while the overall features were characteristic of unbiased repertoires. We observed moderate levels of shared complementarity-determining region 3 (CDR3) clonotypes among individual birds within the α and γ chain repertoires, including the most frequently occurring clonotypes. However, the β and δ repertoires were predominantly unique to each bird. Taken together, our TCR repertoire analysis allowed us to decipher the composition, diversity, and functionality of T cells in chickens. This work not only represents a significant step towards understanding avian T cell biology, but will also shed light on host-pathogen interactions, vaccine development, and the evolutionary history of avian immunology.

description: Optical interferometers with suspended mirrors are the archetype of all current audio-frequency gravitational-wave detectors. The radiation pressure interaction between the motion of the mirror and the circulating optical field in such interferometers represents a pristine form of light-matter coupling, largely due to 30 years of effort in developing high quality optical materials with low mechanical dissipation. However, in all current suspended interferometers, the radiation pressure interaction is too weak to be useful as a resource, and too strong to be neglected. Here, we demonstrate a meter-long interferometer with suspended mirrors, of effective mass $~ 125$ g, where the radiation pressure interaction is enhanced by strong optical pumping to realize a cooperativity of $50$. We probe this regime by observing optomechanically-induced transparency of a weak on-resonant probe. The low resonant frequency and high-Q of the mechanical oscillator allows us to demonstrate transparency windows barely $100$ mHz wide at room temperature. Together with a near-unity ($\sim 99.9\%$) out-coupling efficiency, our system saturates the theoretical delay-bandwidth product, rendering it an optical buffer capable of seconds-long storage times.

description: With the ever increasing size of scientific collaborations and complexity of scientific instruments the software needed to acquire, process and analyze the gathered data is gaining in complexity and size too. Unfortunately the role and career path of scientists and engineers working on software R&D and developing scientific software is neither clearly established nor defined in many fields of natural science. In addition the exchange of information between scientific software development and computer science departments at universities or computing schools is scattered and de-fragmented into individual initiatives. To address the above issues we propose an effort on an European level, which concentrates on strengthening the role of software developers in natural sciences, acts as a hub for exchange of ideas among different stakeholders in computer science and scientific software and forms a lobbying forum for software engineering in natural sciences on an international level.

description: We discuss the zero-temperature susceptibility of elastic manifolds with quenched randomness. It diverges with system size due to low-lying local minima. The distribution of energy gaps is deduced to be constant in the limit of vanishing gaps by comparing numerics with a probabilistic argument. The typical manifold response arises from a level-crossing phenomenon and implies that wetting in random systems begins with a discrete transition. The associated ``jump field'' scales as $ \sim L^{-5/3}$ and $L^{-2.2}$ for (1+1) and (2+1) dimensional manifolds with random bond disorder.

description: Retention time (RT) prediction in chromatography can play an important role for numerous analytical applications, including drug discovery and environmental monitoring. This study aims to enhance RT prediction accuracy by employing deep learning techniques, particularly focusing on transfer learning to adapt models trained on synthetic compounds acquired by High Pressure Liquid chromatography–Mass Spectrometry (HPLC-MS) to predict RTs for natural products in different chromatographic methods. We utilized the extensive METLIN Small Molecule Retention Time (SMRT) dataset, comprising over 80,000 synthetic compounds, to train a deep neural network (DNN). This model was then fine-tuned on smaller datasets of natural products, from the RepoRT database using a two-stage transfer learning approach. Initially, the DNN’s upper layers were frozen to retain knowledge about high level features while training on the new data. Subsequently, all layers were unfrozen for further training with a reduced learning rate, ensuring both general and unique patterns were captured. Hyperparameter optimization was conducted using Optuna, leveraging a 5-fold nested cross-validation to ensure robust performance. The evaluation metrics that we computed were the Mean Absolute Error (MAE), the Median Absolute Error (MedAE) and Mean Absolute Percentage error (MAPE). Transfer learning was then compared with new trained DNNs directly trained on the RepoRT database and showed that the strategy was successful according to the MAE and MadAE metric, although not according to the MAPE. We decided to remove the outliers and noticed that with the cleared data transfer learning performed better considering all the metrics. In the future, it will be necessary to refine this strategy to improve its performance, either by testing it on the same datasets or by incorporating additional data.

description: In einer umfassenden Dokumentation werden sämtliche aktuell und historisch nachgewiesenen Flechten und flechtenbewohnenden Pilze des Odenwaldes behandelt und deren Verbreitung in Punktrasterkarten auf MTB-Quadrantenbasis dargestellt. Aktuell – in einem mehr als zwanzig Jahre umfassenden Beobachtungszeitraum – wurden 660 Flechtenarten und 78 flechtenbewohnende Pilzarten festgestellt. Dies sind für ein fast 2500 km2 großes, nur gut 600 m Meereshöhe erreichendes Gebiet sehr hohe Artenzahlen, die zum einen auf einer überdurchschnittlich gründlichen Erfassung beruhen, zum anderen mit einem flechtengünstigen Klima und der erheblichen Erholung der Flechtenvegetation im Untersuchungszeitraum infolge abnehmender SO2-Belastung zu erklären sind. Die höchste pro Messtischblatt-Quadrant ermittelte Artenzahl beträgt 319, pro Messtischblatt 425 – diese Zahlen übertreffen jene in vergleichbaren Regionen
der Bundesrepublik registrierten deutlich und reichen an die Nachweise im Schwarzwald in hochmontanen Lagen heran. Neu für den Odenwald sind 142 Arten. Für Hessen werden 55, für Baden-Württemberg 39 und für Bayern 32 Arten
von Flechten, fl echtenbewohnenden und fakultativ lichenisierten Pilzen neu nachgewiesen, unter ihnen besonders viele flechtenbewohnende Pilze, die bislang wenig beachtet wurden.

description: In this paper, we assemble a well-defined sample of early-type gravitational lenses extracted from a large collection of 158 systems, and use the redshift distribution of galactic-scale lenses to test the standard cosmological model ($Λ$CDM) and the modified gravity theory (DGP). Two additional sub-samples are also included to account for possible selection effect introduced by the detectability of lens galaxies. Our results show that independent measurement of the matter density parameter ($Ω_m$) could be expected from such strong lensing statistics. Based on future measurements of strong lensing systems from the forthcoming LSST survey, one can expect $Ω_m$ to be estimated at the precision of $ΔΩ_m\sim 0.006$, which provides a better constraint on $Ω_m$ than \textit{Planck} 2015 results. Moreover, use the lens redshift test is also used to constrain the characteristic velocity dispersion of the lensing galaxies, which is well consistent with that derived from the optical spectroscopic observations. A parameter $f_E$ is adopted to quantify the relation between the lensing-based velocity dispersion and the corresponding stellar value. Finally, the accumulation of detectable galactic lenses from future LSST survey would lead to more stringent fits of $Δf_E\sim10^{-3}$, which encourages us to test the global properties of early-type galaxies at much higher accuracy.
