description: This paper formulates the pose estimation problem as nonlinear stochastic filter kinematics evolved directly on the Special Euclidean Group SE(3). Proposed filter guarantees that the errors present in position and Rodriguez vector estimates are semi-globally uniformly ultimately bounded (SGUUB) in mean square, and that they converge to small neighborhood of the origin in probability. Simulation results show the robustness and effectiveness of the proposed filter in presence of high levels of noise and bias associated with the velocity vector as well as body-frame measurements.

description: We study the statistical distribution of the ground state spin for an ensemble of small metallic grains, using a random-matrix toy model. Using the Hartree Fock approximation, we find that already for interaction strengths well below the Stoner criterion there is an appreciable probability that the ground state has a finite, nonzero spin. Possible relations to experiments are discussed.

description: The contribution at hand discusses the thermo-mechanical analysis of a steam turbine rotor, made of a heat-resistantsteel. Thereby, the analysis accounts for the complicated geometry of a real steam turbine rotor, subjected to practical andcomplex thermo-mechanical boundary conditions. Various thermo-mechanical loading cycles are taken into account, includingdifferent starting procedures (cold and warm starts). Within the thermal analysis using the FE code ABAQUS, instationarysteam temperatures as well as heat transfer coefficients are prescribed, and the resulting temperature field serves as input for thesubsequent structural analysis. In order to describe the mechanical behavior of the heat-resistant steel, which exhibits significantrate-dependent inelasticity combined with hardening and softening phenomena, a robust nonlinear constitutive approach, thebinary mixture model, is employed and implemented in ABAQUS in two different ways, i.e. using explicit as well as implicitmethods for the time integration of the governing evolution equations. The numerical performance, the required computationaleffort, and the obtained accuracy of both integration methods are examined with reference to the thermo-mechanical analysis ofa steam turbine rotor, as a typical practical example for the numerical analysis of a complex component. In addition, the obtainedtemperature, stress, and strain fields in the steam turbine rotor are discussed in detail, and the influence of the different startingprocedures is examined closely.

description: Nanostructures fabricated from narrow-gap semiconductors with strong spin-orbit interaction (SOI), such as InAs, can be used to filter momentum modes of electrons and offer the possibility to create and detect spin-polarized currents entirely by electric fields. Here, we present magnetotransport and THz magnetospectroscopy investigations of Hall-bars with back-gates made from in InGaAs/InAlAs quantum well structures with a strained 4 nm InAs inserted channel. The two-dimensional electron gas is at 53 nm depth and has a carrier density of about $6\times10^{11}$ cm$^{-2}$ and mobility of about $2\times10^{5}$ cm$^2$/Vs, after illumination. Electrical and THz optical transport measurements at low temperatures and in high magnetic fields reveal an effective mass of 0.038$m_{0}$ and an anisotropic $g$-factor of up to 20, larger than for bulk InAs or InAs-based heterostructures. We demonstrate that quasi-one-dimensional channels can be formed by micro-laser lithography. The population of subbands is controlled by in-plane gates. Contrary to previous reports symmetric and asymmetric in-plane gate voltages applied to quasi-one dimensional channels did not show indications of SOI-induced anomalies in the conductance.

Year: 2025

description: This study explores the role of theatrical performances in developing students' project competencies at Samarkand International University of Technology (SIUT). Through participation in the university’s theatre, OLTIN MEROS, students engage in project-based learning, enhancing essential skills such as teamwork, communication, critical thinking, leadership, and time management. The upcoming English-language performance of Layli and Majnun serves as a case study to illustrate how artistic engagement fosters professional and academic growth. The findings suggest that integrating theatre into educational programs strengthens students’ ability to manage complex projects, adapt to collaborative environments, and refine their communication skills, making it a valuable pedagogical tool for competency development.

description: Photocatalytic water splitting is a promising way to produce hydrogen, which could serve as an eco-friendly fuel produced from renewable energy sources like the sun. TiO2 is one of themost widely used photocatalysts, but it can only utilize UV light, which constitutes only a very small part of the whole spectrum of natural sunlight. To produce photocatalysts that utilize the solar spectrum more efficiently, it is necessary to modify TiO2 and make it visible light active. In this project, vanadium-modified TiO2 photocatalysts with 1 at%-, 5 at%- and 25 at%V were produced to investigate the role of V-species as a visible light absorber as well as their possible role as a co-catalyst. For V-concentrations of 5 at%- and 25 at%, the resulting catalystsconsisted of composites between TiO2 and V2O5 while no individual VOx compounds could be detected for the low-concentration 1 at%-samples. All of the samples showed an improved visible light absorption.The catalysts were tested for their photocatalytic activity towards OER and HER under UV light in order to investigate the ability of the V-species to act as a co-catalyst. Their role as a light absorber was analysed with HER experiments under visible light with the addition of Pt. All experiments were performed using a sacrificial agent for the respective complementary reduction and oxidation reaction. While none of the synthesized catalysts was active under UV light, the sample with 5 at% was able to produce hydrogen under visible light illumination, contrary to unmodified anatase. Due to the formation of a heterojunction between the two oxides, the V2O5 in the composite structure was able to act as a light absorber, transferring excited electrons into TiO2 where they could then react with protons to form H2.

description: Starting from a recent derivation of the energy production rates in terms of the number of translational and rotational degrees of freedom, a comparative study on different granular temperatures in gas mixtures of inelastic and rough disks or spheres is carried out. Both the homogeneous freely cooling state and the state driven by a stochastic thermostat are considered. It is found that the relaxation number of collisions per particle is generally smaller for disks than for spheres, the mean angular velocity relaxing more rapidly than the temperature ratios. In the asymptotic regime of the undriven system, the rotational-translational nonequipartition is stronger in disks than in spheres, while it is hardly dependent on the class of particles in the driven system. On the other hand, the degree of component-component nonequipartition is higher for spheres than for disks, both for driven and undriven systems. A study of the mimicry effect (whereby a multicomponent gas mimics the rotational-translational temperature ratio of a monocomponent gas) is also undertaken.

description: We present a counting of microstates of a class of dyonic BPS black holes in AdS$_4$ which precisely reproduces their Bekenstein-Hawking entropy. The counting is performed in the dual boundary description, that provides a non-perturbative definition of quantum gravity, in terms of a twisted and mass-deformed ABJM theory. We evaluate its twisted index and propose an extremization principle to extract the entropy, which reproduces the attractor mechanism in gauged supergravity.

description: The lepton angular distributions of the Drell-Yan process in fixed-target experiments are investigated by NLO and NNLO perturbative QCD. We present the calculated angular parameters $λ$, $μ$, $ν$ and the degree of violation of the Lam-Tung relation, $1-λ-2ν$, for the NA10, E615 and E866 experiments. Predictions for the ongoing COMPASS and SeaQuest experiments are also presented. The transverse momentum ($q_T$) distributions of $λ$ and $ν$ show a clear dependence on the dimuon mass ($Q$) while those of $μ$ have a strong rapidity ($x_F$) dependence. Furthermore, $λ$ and $ν$ are found to scale with $q_T/Q$. These salient features could be qualitatively understood by a geometric approach where the lepton angular distribution parameters are expressed in terms of the polar and azimuthal angles of the "natural axis" in the dilepton rest frame.

Subjects: MCRA software cumulative risk assessment mixtures hazard exposure

description: A toolbox has been built to assess risks from combined exposure to multiple chemicals using probabilistic methods. The toolbox has more than 40 modules to address all areas of risk assessment, and includes a data repository with data collected in the EuroMix project. This paper gives an introduction to the toolbox and illustrates its use with examples from the EuroMix project. The toolbox can be used for hazard identification, hazard characterisation, exposure assessment and risk assessment, with special emphasis on the use of in vitro results. Examples shown for hazard identification are the selection of substances relevant for a specific adverse outcome based on adverse outcome pathways and QSAR models. Examples for hazard characterisation are the calculation of benchmark doses and relative potency factors with uncertainty estimates from dose response data, and the use of kinetic models to perform in vitro in vivo extrapolation. Examples for exposure assessment are assessing cumulative exposure at either the external or the internal level, where the latter option is needed in case dietary and non-dietary routes have to be aggregated. Finally, risk assessment is illustrated by graphical displays of the margin of exposure for single substances and cumulated, including uncertainties for the exposure and hazard characterisation estimates.

Hydrodynamic description of long-distance spin transport through noncollinear magnetization states: the role of dispersion, nonlinearity, and damping

description: Nonlocal compensation of magnetic damping by spin injection has been theoretically shown to establish dynamic, noncollinear magnetization states that carry spin currents over micrometer distances. Such states can be generically referred to as dissipative exchange flows (DEFs) because spatially diffusing spin currents are established by the mutual exchange torque exerted by neighboring spins. Analytical studies to date have been limited to the weak spin injection assumption whereby the equation of motion for the magnetization is mapped to hydrodynamic equations describing spin flow and then linearized. Here, we analytically and numerically study easy-plane ferromagnetic channels subject to spin injection of arbitrary strength at one extremum under a unified hydrodynamic framework. We find that DEFs generally exhibit a nonlinear profile along the channel accompanied by a nonlinear frequency tuneability. At large injection strengths, we fully characterize a novel magnetization state we call a contact-soliton DEF (CS-DEF) composed of a stationary soliton at the injection site, which smoothly transitions into a DEF and exhibits a negative frequency tuneability. The transition between a DEF and a CS-DEF occurs at the maximum precessional frequency and coincides with the Landau criterion: a subsonic to supersonic flow transition. Leveraging the hydraulic-electrical analogy, the current-voltage characteristics of a nonlinear DEF circuit are presented. Micromagnetic simulations of nanowires that include magnetocrystalline anisotropy and non-local dipole fields are in qualitative agreement with the analytical results. The magnetization states found here along with their characteristic profile and spectral features provide quantitative guidelines to pursue an experimental demonstration of DEFs in ferromagnetic materials and establishes a unified description for long-distance spin transport.

description: We consider three-dimensional sQED with 2 flavors and minimal supersymmetry. We discuss various models which are dual to Gross-Neveu-Yukawa theories. The $U(2)$ ultraviolet global symmetry is often enhanced in the infrared, for instance to $O(4)$ or $SU(3)$. This is analogous to the conjectured behaviour of non-supersymmetric QED with 2 flavors. A perturbative analysis of the Gross-Neveu-Yukawa models in the $D = 4 - \varepsilon$ expansion shows that the $U(2)$ preserving superpotential deformations of the sQED (modulo tuning mass terms to zero) are irrelevant, so the fixed points with enhanced symmetry are stable. We also construct an example of $\mathcal{N} = 2$ sQED with 4 flavors that exhibits enhanced $SO(6)$ symmetry.

description: Algorithms used for the reconstruction and identification of electrons in the central region of the ATLAS detector at the Large Hadron Collider (LHC) are presented in this paper; these algorithms are used in ATLAS physics analyses that involve electrons in the final state and which are based on the 2015 and 2016 proton-proton collision data produced by the LHC at $\sqrt{s}$ = 13 TeV. The performance of the electron reconstruction, identification, isolation, and charge identification algorithms is evaluated in data and in simulated samples using electrons from $Z\rightarrow ee$ and $J/ψ\rightarrow ee$ decays.

description: Many governments have placed priority on excellence in higher education as part of their policy agendas. Processes for recruitment and career advancement in universities thus have a critical role. The efficiency of faculty selection processes can be evaluated by comparing the subsequent performance of competition winners against that of the losers and the pre-existing staff of equal academic rank. Our study presents an empirical analysis concerning the recruitment procedures for associate professors in the Italian university system. The results of a bibliometric analysis of the hard science areas reveal that new associate professors are on average more productive than the incumbents. However a number of crucial concerns emerge, in particular concerning occurrence of non-winner candidates that are more productive than the winners over the subsequent triennium, and cases of winners that are completely unproductive. Beyond the implications for the Italian case, the analysis offers considerations for all decision-makers regarding the ex post evaluation of the efficiency of the recruitment process and the desirability of providing selection committees with bibliometric indicators in support of evaluation (i.e. informed peer review).

description: Reinforcement learning (RL) is currently one of the most active machine learning research fields. RL algorithms have been successfully deployed ubiquitously in many real-world application domains, such as autonomous vehicles, intelligent production sites, and finance. Despite the many advances made in recent years, there are still fundamental challenges that need to be addressed before RL can be reliably applied in industrial applications. One of these problems is the sheer amount of training data that is needed to train deep RL agents. Model-based RL is a branch of RL algorithms that learn a model of the agent or its environment which is then leveraged to generate new training data or to plan ahead. Model-based approaches are expected to reduce the required amount of training data to be sampled from an environment, down to a level that allows RL algorithms to be trained in environments where it is hard to generate sufficient data. The goal of this work is to investigate the advantages that model-based RL algorithms bring. To this end, we adapt an existing model-based RL algorithm and compare its performance with that of common, model-free RL algorithms that mark the current State-of-the-Art. The application domain in which we conduct the experiments is in the field of autonomous racing. In our experiments, agents are trained to minimize lap times in time-trial races. The experiments aim to evaluate algorithms, that were trained in simulation, with respect to their ability to be deployed in the real world. We also compare the flexibility of the algorithms to produce comparable results on other, unseen race tracks. Last but not least, we also investigate the training behavior of the different algorithms. The experiments are performed both in a simulation environment, implemented specifically for this work, and on a prototyping platform based on a small remote-controlled car.

description: One obstacle that has slowed the development of electrically gated metal-oxide-semiconductor (MOS) singlet-triplet qubits is the frequent lack of observed spin blockade, even in samples with large singlet-triplet energy splittings. We present theoretical and experimental evidence that the cause of this problem in MOS double quantum dots is the stray positive charges in the oxide inducing accidental levels near the device's active region that allow spin blockade lifting. We also present evidence that these effects can be mitigated by device design modifications, such as overlapping gates.

description: The increasing concerns and activities around global climate change induced newenergy and emission policies. High industrial emissions must be targeted to lower the carbon dioxide impact.The focus of this work is on the first step of a two step biotechnological process with industrial flue gases containing hydrogen, carbon dioxide, carbon monoxide, oxygen, nitrogen and methane for conversion into valuable products. An autotrophic fermentation process with Acetobacterium woodii was characterized and described.The utilized facultative an aerobic bacteria Acetobacterium woodiiis known for growing chemolithoautotrophically on carbon dioxide and hydrogen with acetate as the sole product.Batch and chemostat cultivations were applied to study different influences such as mass transfer, specific reaction rates and productivity. Due to in adequate masstransfer the process was identified as hydrogen limited . Final acetate concentrations of 25 g/L were measured at low biomass concentrations of 0.8 to 1.2 g/L in less than five days under autotrophic conditions. The highest accomplished biomass specific reaction rate was 13.20 g/g d.Small scale serum bottle experiments were used to evaluate in hibitory effects ofcarbon monoxide and oxygen. Contradictory results were obtained from these tests.Furthermore, online calculators and possible online sensoring (within the processinformation management system Lucullus) for solid online process screening were evaluated. This led to effective online acetate monitoring via a soft sensor basedon the base signal.

description: We study the anomalous FCNC $tqγ$ and $tqg$ couplings via $pp\to Wbγ+X$ signal process including realistic detector effects for both leptonic and hadronic decay channels of the W boson at 100 TeV FCC-hh. The relevant background are considered in the cut based analysis to obtain not only limits on the anomalous $λ$ and $ζ$ couplings but also branching ratios of $t\to qγ$ and $t\to qg$ decay channels. We find that the sensitivity to the branching ratio of $t \to q γ$ channel is three order better than the available LHC experimental limits, and it is comparable for the branching ratio of the $t\to qg$ decay channel with an integrated luminosity of 10 ab$^{-1}$ at 2$σ$ significance level.

description: We consider the thermally activated escape of an overdamped Brownian particle over a potential barrier in the presence of periodic driving. A time-dependent path-integral formalism is developed which allows us to derive asymptotically exact weak-noise expressions for both the instantaneous and the time-averaged escape rate. Our results comprise a conceptionally new, systematic treatment of the rate prefactor multiplying the exponentially leading Arrhenius factor. Moreover, an estimate for the deviations at finite noise-strengths is provided and a supersymmetry-type property of the time averaged escape rate is verified. For piecewise parabolic potentials, the rate-expression can be evaluated in closed analytical form, while in more general cases, as exemplified by a cubic potential, an action-integral remains to be minimized numerically. Our comparison with very accurate numerical results demonstrates an excellent agreement with the theoretical predictions over a wide range of driving strengths and driving frequencies.

description: We propose that the low temperature discrepancy between simple d-wave models of the microwave conductivity and existing experiments on single crystals of YBCO can be resolved by including the scattering of quasiparticles from "holes" of the order parameter at impurity sites. Within a framework proposed previously, we find in particular excellent agreement with data of Hosseini et al. on slightly overdoped YBCO samples over the entire temperature range down to about 2-3K, and for a wide range of frequencies. Remaining discrepancies in the "universal" regime at very low temperatures are discussed.

description: Two wild-growing Brassicaceae plants of Croatian origin, Aurinia leucadea (Guss.) K. Koch and Lepidium draba L., were investigated to uncover glucosinolates via GC/MS analysis of their degradation products. The main constituents of Aurinia leucadea (Guss.) K.Koch distillate were hex-5-enenitrile (28.8%) and but-3-enyl isothiocyanate (18.8%), while 4,5-epithiopentanenitrile (50%) and 5,6-epithiohexanenitrile (18.5%) were the main volatile compounds in autolysate. 4-(Methylsulfanyl)butyl isothiocyanate (96.4%) constituted almost the entire Lepidium draba L. distillate, while the autolysate was characterized by 4-(methylsulfinyl)butyl isothiocyanate (57.3%). So, regarding the glucosinolate degradation products, the main glucosinolates of A. leucadea were glucobrassicanapin and gluconapin, and of L. draba glucoerucin and glucoraphanin.

description: $β$-decay, a process that changes a neutron into a proton (and vice versa), is the dominant decay mode of atomic nuclei. This decay offers a unique window to physics beyond the standard model, and is at the heart of microphysical processes in stellar explosions and the synthesis of the elements in the Universe. For 50 years, a central puzzle has been that observed $β$-decay rates are systematically smaller than theoretical predictions. This was attributed to an apparent quenching of the fundamental coupling constant $g_A \simeq $ 1.27 in the nucleus by a factor of about 0.75 compared to the $β$-decay of a free neutron. The origin of this quenching is controversial and has so far eluded a first-principles theoretical understanding. Here we address this puzzle and show that this quenching arises to a large extent from the coupling of the weak force to two nucleons as well as from strong correlations in the nucleus. We present state-of-the-art computations of $β$-decays from light to heavy nuclei. Our results are consistent with experimental data, including the pioneering measurement for $^{100}$Sn. These theoretical advances are enabled by systematic effective field theories of the strong and weak interactions combined with powerful quantum many-body techniques. This work paves the way for systematic theoretical predictions for fundamental physics problems. These include the synthesis of heavy elements in neutron star mergers and the search for neutrino-less double-$β$-decay, where an analogous quenching puzzle is a major source of uncertainty in extracting the neutrino mass scale.

description: Let $W$ be an $n$-dimensional vector space over a finite field $\mathbb{F}_q$ of any characteristic and $mW$ denote the direct sum of $m$ copies of $W$. Let $\mathbb{F}_q[mW]^{{\rm GL}(W)}$ and $\mathbb{F}_q(mW)^{{\rm GL}(W)}$ denote the vector invariant ring and vector invariant field respectively where ${\rm GL}(W)$ acts on $W$ in the standard way and acts on $mW$ diagonally. We prove that there exists a set of homogeneous invariant polynomials $\{f_{1},f_{2},\ldots,f_{mn}\}\subseteq \mathbb{F}_q[mW]^{{\rm GL}(W)}$ such that $\mathbb{F}_q(mW)^{{\rm GL}(W)}=\mathbb{F}_q(f_{1},f_{2},\ldots,f_{mn}).$ We also prove the same assertions for the special linear groups and the symplectic groups in any characteristic, and the unitary groups and the orthogonal groups in odd characteristic.

description: Using the three-particle quantization condition recently obtained in the particle-dimer framework, the finite-volume energy shift of the two lowest three-particle scattering states is derived up to and including order $L^{-6}$. Furthermore, assuming that a stable dimer exists in the infinite volume, the shift for the lowest particle-dimer scattering state is obtained up to and including order $L^{-3}$. The result for the lowest three-particle state agrees with the results from the literature, and the result for the lowest particle-dimer state reproduces the one obtained by using the Luescher equation.

description: Using standard results from higher (secondary) index theory, we prove that the positive scalar curvature bordism groups of a cartesian product GxZ are infinite in dimension 4n if n>0 G a group with non-trivial torsion. We construct representatives of each of these classes which are connected and with fundamental group GxZ. We get the same result in dimension 4n+2 (n>0) if G is finite and contains an element which is not conjugate to its inverse. This generalizes the main result of Kazaras, Ruberman, Saveliev, "On positive scalar curvature cobordism and the conformal Laplacian on end-periodic manifolds" to arbitrary even dimensions and arbitrary groups with torsion.

description: We study the 1-dimensional Heisenberg antiferromagnet with s=1/2 using a Majorana representation of the s=1/2 spins. A simple Hartree-Fock approximation of the resulting model gives a bilinear fermionic description of the model. This description is rotationally invariant and gives power-law correlations in the ``ground state'' in a natural fashion. The excitations are a two-parameter family of particles, which are spin-1 objects. These are contrasted to the ``spinon'' spectrum, and the technical aspects of the representation are discussed, including the problem of redundant states.

A. Meyer, family Araliaceae). Their structures were determined by comprehensive chemical and spectroscopic analysis. In addition, what’s even more concerning is that protodioscin was isolated for the first time from Panax ginseng.

description: The high-value agarwood oil, largely used in perfumery is generally graded by the traditional method of sensorial assessment. The compositional complexity and variation made its quality control challenging. Besides, non-volatile contaminants and adulterants are the bottlenecks in gas-chromatographic detection. Herein, a HPTLC based technique was developed for the quality assessment of agarwood oil from Northeast India. A ‘marker band’ (anisylacetone and oxygenated sesquiterpene rich) on HPTLC profile, containing major peaks of the oil and characteristic agarwood aroma was quantified to assess the quality. The developed method was validated in terms of specificity, linearity, sensitivity, recovery and precision. The application of the method in test samples of three different grades indicated a positive correlation between ‘marker band’ quantity and oil quality. Its abundance in the superior grade oil was >50% and <20% in poor grade. It can be an efficient analytical tool for the quality assessment and grading of agarwood oil.
