description: Achieving a high intensity in inelastic scanning tunneling spectroscopy (IETS) is important for precise measurements. The intensity of the IETS signal can vary by up to a factor of 3 for various tips without an apparent reason accessible by scanning tunneling microscopy (STM) alone. Here, we show that combining STM and IETS with atomic force microscopy enables carbon monoxide front-atom identification, revealing that high IETS intensities for CO/Cu(111) are obtained for single-atom tips, while the intensity drops sharply for multiatom tips. Adsorption of the CO molecule on a Cu adatom [CO/Cu/Cu(111)] such that the molecule is elevated over the substrate strongly diminishes the tip dependence of IETS intensity, showing that an elevated position channels most of the tunneling current through the CO molecule even for multiatom tips, while a large fraction of the tunneling current bypasses the CO molecule in the case of CO/Cu(111).

description: The deep connection between thermodynamics, computation, and information is now well established both theoretically and experimentally. Here, we extend these ideas to show that thermodynamics also places fundamental constraints on statistical estimation and learning. To do so, we investigate the constraints placed by (nonequilibrium) thermodynamics on the ability of biochemical signaling networks within cells to estimate the concentration of an external signal. We show that accuracy is limited by energy consumption, suggesting that there are fundamental thermodynamic constraints on statistical inference.

 Tilte: Concept for a sustainable development of the green spaces of the Justus Liebig University Gießen Short summary In Germany, the proportion of people living in cities is more than 75% and constantly increasing. Urban green spaces, which are as green islands surrounded by buildings and infrastructure areas, potentially fulfill a large number of important functions. They are mostly used for recreation purposes and have been proven to have positive effects on human health and psyche. However, urban green spaces also make important contributions to urban climate, carbon storage, water retention and can also take over important ecological functions as habitats for plants and animals. Justus-Liebig-University of Giessen is one of the most important landowners in the Giessen. These areas contain a large number of unsealed green spaces of various sizes. In the context of the development of a sustainability strategy, the need but also the great potential to develop the JLU-owned green spaces more sustainably was recognized. However, there is a lack of an overall concept to align green space management with sustainability aspects and to systematically implement measures to improve green space functions. The project is intended to initiate the transformation to a more sustainable green space design and management. The project addresses a large number of sustainable target functions: (a) increasing biodiversity, (b) increasing carbon storage and (c) water storage capacity, (d) improving the urban climate, (e) increasing the recreational function for JLU members and the city population and (f) the increased integration of sustainability aspects in teaching and research. With project progress, measures for the sustainable development of the JLU green spaces will be implemented and their impact on the above mentioned target functions will be evaluated.

description: Extremely weakly interacting particles like the gravitino may be stable enough on cosmological time scales to constitute a good dark matter candidate even in the presence of R-parity violation. We consider the possibility that the recently identified 3.5 keV x-ray line can be generated in light gravitino decays to neutrinos and photons. We find that this is indeed possible in loop processes induced by trilinear lepton-number-violating couplings. We show that in order to avoid overproduction of gravitinos, the reheating temperature has to be at most around 100 GeV to 1 TeV. Finally we briefly discuss associated LHC phenomenology due to a relatively light gluino and multijet/multilepton events from R-parity violating decays of neutralinos.

description: Safety is a critical concern for urban flights of autonomous Unmanned Aerial Vehicles. In populated environments, risk should be accounted for to produce an effective and safe path, known as risk-aware path planning. Risk-aware path planning can be modeled as a Constrained Shortest Path (CSP) problem, aiming to identify the shortest possible route that adheres to specified safety thresholds. CSP is NP-hard and poses significant computational challenges. Although many traditional methods can solve it accurately, all of them are very slow. Our method introduces an additional safety dimension to the traditional A* (called ASD A*), enabling A* to handle CSP. Furthermore, we develop a custom learning-based heuristic using transformer-based neural networks, which significantly reduces the computational load and improves the performance of the ASD A* algorithm. The proposed method is well-validated with both random and realistic simulation scenarios.

description: We study phenomenological constraints in a simple $S\bar{E} χ$y extension of the Standard Model (SM) with a 125 GeV Higgs, a vector-like heavy electron $(E)$, a complex scalar electron $(S)$ and a standard model singlet Dirac fermion $(χ)$. The interactions among the dark matter candidate $χ$ and the standard model particles occur via loop-induced processes involving the Yukawa interaction $S\bar{E} χ$y. The model is an explicit perturbative realization of so-called magnetic dark matter. The field content allows for a cancelation of quadratic divergences in the scalar masses at one-loop, a phenomenon which we refer to as perturbative naturality. The basic model is constrained dominantly by direct detection experiments and its parameter space can be nearly entirely covered by up-coming ton-scale direct detection experiments. We conclude this work by discussing different variations of the model.

Goddess and Politician: Examining Motherhood in the Contemporary White Power Movement

Subjects: subject: white power

description: This paper proposes that the women of contemporary white power exclusively embody the singular role of motherhood, disputing the pre-established multi-role model proposed by scholar Kathleen Blee. Motherhood is a dominant and inevitable identity, goal, and purpose for female racist activists, though it may be exercised in different ways: either in the public sphere or private sphere. This study delves into the dichotomy between female racist activists in each space, investigating how they experience empowerment and acceptance through motherhood in the public sphere, as shown by the "Mother as Politician" archetype, and how motherhood itself becomes a form of activism in the private sphere, as shown by the "Mother as Goddess." Both representations of motherhood serve as manifestations of the paper’s central argument: the survival of the white power movement depends on both female natality and female submission; it depends on placing women in a role that is both political and domestic, sacred and weaponized.

description: We employ the recently proposed formalism of the "horizon wave-function" to investigate the emergence of a horizon in models of black holes as Bose-Einstein condensates of gravitons. We start from the Klein-Gordon equation for a massless scalar (toy graviton) field coupled to a static matter current. The (spherically symmetric) classical field reproduces the Newtonian potential generated by the matter source, and the corresponding quantum state is given by a coherent superposition of scalar modes with continuous occupation number. Assuming an attractive self-interaction that allows for bound states, one finds that (approximately) only one mode is allowed, and the system can be confined in a region of the size of the Schwarzschild radius. This radius is then shown to correspond to a proper horizon, by means of the horizon wave-function of the quantum system, with an uncertainty in size naturally related to the expected typical energy of Hawking modes. In particular, this uncertainty decreases for larger black hole mass (with larger number of light scalar quanta), in agreement with semiclassical expectations, a result which does not hold for a single very massive particle. We finally speculate that a phase transition should occur during the gravitational collapse of a star, ideally represented by a static matter current and Newtonian potential, that leads to a black hole, again ideally represented by the condensate of toy gravitons, and suggest an effective order parameter that could be used to investigate this transition.

The nature and rationality of trust and trustworthiness

subject: Reliability

description: Trust and trustworthiness are highly important concepts; Trusting well enables us to achieve things we cannot do alone and to discover things that we cannot check for ourselves. Issues of trust sit in the intersection of ethics and epistemology; it is commonly thought of as a moral good to be trustworthy and trusting the testimony of others can be a valuable source of knowledge. By trusting too easily, however, we become hopelessly naïve and risk falling prey to scams and lies. Knowing when to trust is therefore of significant practical value. The aim of this thesis is to come to a greater understanding of these concepts. The first three chapters deal with what trust and trustworthiness are. In the first, I argue that trust is a kind of reliance, rather than a kind of belief. In the second, I argue that trust is specifically reliance on another to be trustworthy. The third chapter presents a theory of trustworthiness according to which being trustworthy is a matter of keeping commitments. The following two chapters are about the rationality of trust. The first considers various ideas proposed for what justifies trusting someone and shows why they are not successful. The second lays out my own view, on which trust is justified by both evidence and practical reasons addressing another’s trustworthiness. Finally, I consider the relationship between commitments and responsibility. It is argued that, by accepting a commitment to do something from another, one is absolved of responsibility for ensuring that it is done. This is also found to help explain why holding victims responsible is a mistake. Ultimately, a holistic theory of trust and trustworthiness is proposed, which I believe has significant advantages over those already in the literature and will be useful in future philosophical research.

Both quenches take the system to the chaotic domain, the energy distribution of the initial states approaches a Breit-Wigner shape, the fidelity (Loschmidt echo) decays exponentially, and thermalization becomes viable.

description: Pt-Al and Pt-Y-Al thin film electrodes on yttria-stabilised zirconia electrolytes were prepared by dealloying of co-sputtered Pt-Al or Pt-Y-Al films. The selective dissolution of Al from the Pt-alloy compound causes the formation of a highly porous nanowire network with a mean branch thickness below 25 nm and a pore intercept length below 35 nm. The oxygen reduction capability of the resulting electrodes was analysed in a micro-solid oxide fuel cell setup at elevated temperatures (598-873 K). Here, we demonstrate that these nanoporous thin films excel "state-of-the-art" fuel cell electrodes in terms of catalytic activity and thermal stability. The nanoporous Pt electrodes exhibit exchange current densities that are up to 13 times higher than conventional Pt electrodes, measured at 648 K. It is shown that the enhanced catalytic activity of these Pt electrodes is achieved through the engineering of the materials d-bands due to the addition of yttrium as ternary constituent.

description: We address the issue of model selection in beta regressions with varying dispersion. The model consists of two submodels, namely: for the mean and for the dispersion. Our focus is on the selection of the covariates for each submodel. Our Monte Carlo evidence reveals that the joint selection of covariates for the two submodels is not accurate in finite samples. We introduce two new model selection criteria that explicitly account for varying dispersion and propose a fast two step model selection scheme which is considerably more accurate and is computationally less costly than usual joint model selection. Monte Carlo evidence is presented and discussed. We also present the results of an empirical application.

description: An effective low-energy Hamiltonian of itinerant electrons for iridium oxide Na2IrO3 is derived by an ab initio downfolding scheme. The model is then reduced to an effective spin model on a honeycomb lattice by the strong coupling expansion. Here we show that the ab initio model contains spin-spin anisotropic exchange terms in addition to the extensively studied Kitaev and Heisenberg exchange interactions, and allows to describe the experimentally observed zigzag magnetic order, interpreted as the state stabilized by the antiferromagnetic coupling of the ferromagnetic chains. We clarify possible routes to realize quantum spin liquids from existing Na2IrO3.

description: Нетуберкулезные микобактерии – группа микроорганизмов, участвующих в развитии микобактериозов различной локализации. Пациенты с муковисцидозом имеют высокие риски инфицирования данными бактериями. Во многих странах мира отмечена высокая распространенность не-туберкулезных микобактерий у пациентов с муковисцидозом, которая варьирует от 5 до 20 %. Согласно данным, представленным в Регистре больных муковисцидозом Российской Федерации, за 2019 г. доля инфицированных нетуберкулезными микобактериями составила всего 1,0 %. В работе представлены данные анализа распространенности нетуберкулезных микобактерий в клиническом материале от пациентов с муковисцидозом из 58 регионов России. Цель: про-анализировать распространенность нетуберкулезных микобактерий в клиническом материале от пациентов с муковисцидозом и изучить структуру сопутствующей флоры в образцах клинического материала. Материалы и методы. В период с 2017 по 2020 г. были выполнены микро-биологические исследования 5 547 образцов клинического материала, собранного от 1 148 пациентов с муковисцидозом. Первичный посев образцов выполняли в соответствии с методика-ми, предложенными руководством по микробиологической диагностике инфекций дыхательных путей у пациентов с муковисцидозом. Для видовой идентификации микроорганизмов использовали метод матрично-активированной лазерной десорбции/ионизации времяпролетной масс-спектрометрии. Результаты. За анализируемый период было выделено 56 штаммов Mycobacte-rium abscessus complex от 21 пациента с муковисцидозом. Было идентифицировано 223 штамма микроорганизмов, выделенных от пациентов совместно с Mycobacterium abscessus complex. Большинство из них являются клинически значимыми и принимают участие в развитии инфекционного процесса. Заключение. По результатам исследования доля пациентов, от которых были выделены Mycobacterium abscessus complex, составила 1,8 %. Внедрение алгоритмов по подбору оптимальных питательных сред и сроков культивирования, возможно, повысит вероятность обнаружения нетуберкулезных микобактерий. В дальнейшем это позволит корректировать назначения антимикробной терапии и снизить вероятность развития осложнений, вызванных нетуберкулезными микобактериями, у пациентов этой группы.

description: We describe an adiabatic state transfer mechanism that allows for high-fidelity transfer of a microwave quantum state from one cavity to another through an optical fiber. The conversion from microwave frequency to optical frequency is enabled by an optomechanical transducer. The transfer process utilizes a combined dark state of the mechanical oscillator and fiber modes, making it robust against both mechanical and fiber loss. We anticipate this scheme being an enabling component of a hybrid quantum computing architecture consisting of superconducting qubits with optical interconnects.

description: In previous work we have presented Schwarzschild models of the Sculptor dSph, demonstrating that this system could be embedded in dark matter halos that are either cusped or cored. Here we show that the non-parametric distribution function recovered through Schwarschild's method is bimodal in energy and angular momentum space for all best fitting mass models explored. We demonstrate that this bimodality is directly related to the two components known to be present in Sculptor through stellar populations analysis, although our method is purely dynamical in nature and does not use this prior information. It therefore constitutes independent confirmation of the existence of two physically distinct dynamical components in Sculptor and suggests a rather complex assembly history for this dwarf galaxy.

description: With continuous advancements in science and technology, there is increasing focus on environmental sustainability, leading to heightened interest in autonomous electric vehicles (AEVs). AEVs hold significant potential for enhancing electric mobility, energy efficiency, environmental preservation, and driving capabilities. They offer numerous advantages that could revolutionize transportation and urban lifestyles, notably by improving road safety through the reduction of human error, a leading cause of accidents. This paper presents a comprehensive simulation of an AEV by developing and integrating models for the driving system, battery, motor, transmission, and vehicle body within the MATLAB/Simulink environment. Each component is configured and interconnected to create a pure vehicle model. The simulation is conducted under UDDS cycle conditions to evaluate the vehicle's performance in speed maintenance, driving distance, acceleration capabilities, and battery state-of-charge (SoC) dynamics. The results demonstrate that the vehicle exhibits strong output characteristics. Furthermore, the driver model incorporates an energy brake recovery function, which, when set to a 50% recovery efficiency, increases the driving distance by 25% compared to a vehicle without this function.

This formula was verified in the seminal work of Talagrand and later generalized to the mixed p-spin models by Panchenko. In this paper, we prove that the minimizer in Parisi's formula is unique at any temperature and external field by establishing the strict convexity of the Parisi functional.

description: Dark matter (DM) with sizeable self-interactions mediated by a light species offers a compelling explanation of the observed galactic substructure; furthermore, the direct coupling between DM and a light particle contributes to the DM annihilation in the early universe. If the DM abundance is due to a dark particle-antiparticle asymmetry, the DM annihilation cross-section can be arbitrarily large, and the coupling of DM to the light species can be significant. We consider the case of asymmetric DM interacting via a light (but not necessarily massless) Abelian gauge vector boson, a dark photon. In the massless dark photon limit, gauge invariance mandates that DM be multicomponent, consisting of positive and negative dark ions of different species which partially bind in neutral dark atoms. We argue that a similar conclusion holds for light dark photons; in particular, we establish that the multi-component and atomic character of DM persists in much of the parameter space where the dark photon is sufficiently light to mediate sizeable DM self-interactions. We discuss the cosmological sequence of events in this scenario, including the dark asymmetry generation, the freeze-out of annihilations, the dark recombination and the phase transition which gives mass to the dark photon. We estimate the effect of self-interactions in DM haloes, taking into account this cosmological history. We place constraints based on the observed ellipticity of large haloes, and identify the regimes where DM self-scattering can affect the dynamics of smaller haloes, bringing theory in better agreement with observations. Moreover, we estimate the cosmological abundance of dark photons in various regimes, and derive pertinent bounds.

We also find there will be much stricture growth on large scales in the SCG scenario than in $Λ$CDM and the variations of $σ_{8}$ and $S_3$ between SCG and $Λ$CDM can not be discriminated.

description: Recently, the Weinberg compositeness condition of a bound state was generalized to account for resonant states and higher partial waves. We apply this extension to the case of the $Λ(1520)$ resonance and quantify the weight of the meson-baryon components in contrast to other possible genuine building blocks. This resonance was theoretically obtained from a coupled channels analysis using the s-waves $πΣ^*$, $KΞ^*$ and the d-waves $\bar{K}N$ and $πΣ$ channels applying the techniques of the chiral unitary approach. We obtain that this resonance is essentially dynamically generated from these meson-baryon channels, leaving room for only $15 \%$ weight of other kind of components into its wave function.

description: We explore the possibility of emergent cosmology using the effective potential formalism. We discover new models of emergent cosmology which satisfy the constraints posed by the cosmic microwave background (CMB). We demonstrate that, within the framework of modified gravity, the emergent scenario can arise in a universe which is spatially open/closed. By contrast, in general relativity (GR) emergent cosmology arises from a spatially closed past-eternal Einstein Static Universe (ESU). In GR the ESU is unstable, which creates fine tuning problems for emergent cosmology. However, modified gravity models including Braneworld models, Loop Quantum Cosmology (LQC) and Asymptotically Free Gravity result in a stable ESU. Consequently, in these models emergent cosmology arises from a larger class of initial conditions including those in which the universe eternally oscillates about the ESU fixed point. We demonstrate that such an oscillating universe is necessarily accompanied by graviton production. For a large region in parameter space graviton production is enhanced through a parametric resonance, casting serious doubts as to whether this emergent scenario can be past-eternal.

description: In this paper the empirical observability Gramian calculated around the operating region of a power system is used to quantify the degree of observability of the system states under specific phasor measurement unit (PMU) placement. An optimal PMU placement method for power system dynamic state estimation is further formulated as an optimization problem which maximizes the determinant of the empirical observability Gramian and is efficiently solved by the NOMAD solver, which implements the Mesh Adaptive Direct Search (MADS) algorithm. The implementation, validation, and also the robustness to load fluctuations and contingencies of the proposed method are carefully discussed. The proposed method is tested on WSCC 3-machine 9-bus system and NPCC 48-machine 140-bus system by performing dynamic state estimation with square-root unscented Kalman filter. The simulation results show that the determined optimal PMU placements by the proposed method can guarantee good observability of the system states, which further leads to smaller estimation errors and larger number of convergent states for dynamic state estimation compared with random PMU placements. Under optimal PMU placements an obvious observability transition can be observed. The proposed method is also validated to be very robust to both load fluctuations and contingencies.

description: In this paper we present a general approach to multivariate periodic wavelets generated by scaling functions of de la Vallée Poussin type. These scaling functions and their corresponding wavelets are determined by their Fourier coefficients, which are sample values of a function, that can be chosen arbitrarily smooth, even with different smoothness in each direction. This construction generalizes the one-dimensional de la Vallée Poussin means to the multivariate case and enables the construction of wavelet systems, where the set of dilation matrices for the two-scale relation of two spaces of the multiresolution analysis may contain shear and rotation matrices. It further enables the functions contained in each of the function spaces from the corresponding series of scaling spaces to have a certain direction or set of directions as their focus, which is illustrated by detecting jumps of certain directional derivatives of higher order.

description: To discover new regulatory pathways in B lymphoma cells, we performed a combined analysis of experimental, clinical and global gene expression data. We identified a specific cluster of genes that was coherently expressed in primary lymphoma samples and suppressed by activation of the B cell receptor (BCR) through aIgM treatment of lymphoma cells in vitro. This gene cluster, which we called BCR. 1, includes numerous cell cycle regulators. A reduced expression of BCR. 1 genes after BCR activation was observed in different cell lines and also in CD10(+) germinal center B cells. We found that BCR activation led to a delayed entry to and progression of mitosis and defects in metaphase. Cytogenetic changes were detected upon long-term aIgM treatment. Furthermore, an inverse correlation of BCR. 1 genes with c-Myc co-regulated genes in distinct groups of lymphoma patients was observed. Finally, we showed that the BCR. 1 index discriminates activated B cell-like and germinal centre B cell-like diffuse large B cell lymphoma supporting the functional relevance of this new regulatory circuit and the power of guided clustering for biomarker discovery.

description: We propose the interaction of two electrons in a triple quantum dot as a minimal system to control long range superexchange transitions. These are probed by transport spectroscopy. Narrow resonances appear indicating the transfer of charge from one side of the sample to the other with the central one being occupied only virtually. We predict that two different intermediate states establish the two arms of a one dimensional interferometer. Configurations of destructive interference of the two superexchage trajectories totally block the current through the system. We emphasize the role of spin correlations giving rise to lifetime-enhanced resonances.

description: Due to the increased popularity of herbomineral preparations in the healthcare sector, a new proprietary herbomineral formulation was formulated consisting of ashwagandha root extract and three minerals viz. zinc chloride, magnesium gluconate, and sodium selenate. The objective of the study was to evaluate the in vitro effect of Biofield Energy Healing (The Trivedi Effect®) on the test formulation using murine splenocyte cells. The herbomineral formulation was divided into two parts; one defined as the control, while the other part was treated with the Biofield Energy Healing Treatment performed from a remote distance by twenty renowned Biofield Energy Healers (The Trivedi Effect®) and defined as the Biofield Treated formulation. The splenocyte cells were exposed to test formulations at concentration from 0.00001053 to 10.53 µg/mL and were analyzed after 48 hours for cell viability using MTT assay. The expression of the cytokines (TNF-α, IFN-γ, IL-1β, and MIP-1α) was determined using ELISA assay. The cell viability data showed that all the tested concentration ranges were found to be safe with percentage cell viability at more than 80%. Further, TNF-α expression was significantly inhibited in the Biofield Treated test formulation group with respect to the vehicle control, while at 0.001053 and 0.1053 µg/mL, the expression was suppressed by 1.70% and 8.16%, respectively in the Biofield Treated test formulation compared to the untreated formulation. However, a significant immunosuppression was reported in IFN-γ expression at 0.00001053, 0.0001053, 0.01053, 0.1053, and 1.053 µg/mL by 12.63%, 2.31%, 8.31%, 9.15%, and 7.86%, respectively in the Biofield Treated test formulation compared with the untreated test formulation. The MIP-1α expression was inhibited by 8.31%, 21.53%, and 8.70% at 0.0001053, 0.01053, and 0.1053 µg/mL, respectively in the Biofield Treated formulation compared with the untreated test formulation. However, IL-1β expression was significantly suppressed by 19.72% at concentration 0.00001053 µg/mL in the Biofield Treated test formulation compared with the untreated test formulation. Thus, the down-regulation of tested cytokines and chemokines in the Biofield Energy Healing test formulation might be applicable for controlling acute and chronic inflammation in many clinical diseases. Overall, the results demonstrated that The Trivedi Effect®- Biofield Energy Healing (TEBEH) has the capacity to potentiate the immunomodulatory activity of the test formulation, which can be useful against autoimmune disorders. Biofield Treated Test formulation may also be useful in anti-aging, anti-inflammatory, stress management and in preventing immune-mediated tissue damage in organ transplants by improving overall health and quality of life.
