description: The evolution of helium stars with initial masses in the range 1.6 to 120 Msun is studied, including the effects of mass loss by winds. These stars are assumed to form in binary systems when their expanding hydrogenic envelopes are promptly lost just after helium ignition. Significant differences are found with single star evolution, chiefly because the helium core loses mass during helium burning rather than gaining it from hydrogen shell burning. Consequently presupernova stars for a given initial mass function have considerably smaller mass when they die and will be easier to explode. Even accounting for this difference, the helium stars with mass loss develop more centrally condensed cores that should explode more easily than their single-star counterparts. The production of low mass black holes may be diminished. Helium stars with initial masses below 3.2 Msun experience significant radius expansion after helium depletion, reaching blue supergiant proportions. This could trigger additional mass exchange or affect the light curve of the supernova. The most common black hole masses produced in binaries is estimated to be about 9 Msun. A new maximum mass for black holes derived from pulsational pair-instability supernovae is derived - 46 Msun, and a new potential gap at 10 - 12 Msun is noted. Models pertinent to SN 2014ft are presented and a library of presupernova models is generated.

description: Quantum computers are expected to outperform conventional computers for a range of important problems, from molecular simulation to search algorithms, once they can be scaled up to large numbers of quantum bits (qubits), typically millions. For most solid-state qubit technologies, e.g. those using superconducting circuits or semiconductor spins, scaling poses a significant challenge as every additional qubit increases the heat generated, while the cooling power of dilution refrigerators is severely limited at their operating temperature below 100 mK. Here we demonstrate operation of a scalable silicon quantum processor unit cell, comprising two qubits confined to quantum dots (QDs) at $\sim$1.5 Kelvin. We achieve this by isolating the QDs from the electron reservoir, initialising and reading the qubits solely via tunnelling of electrons between the two QDs. We coherently control the qubits using electrically-driven spin resonance (EDSR) in isotopically enriched silicon $^{28}$Si, attaining single-qubit gate fidelities of 98.6% and coherence time $T_2^*$ = 2$μ$s during `hot' operation, comparable to those of spin qubits in natural silicon at millikelvin temperatures. Furthermore, we show that the unit cell can be operated at magnetic fields as low as 0.1 T, corresponding to a qubit control frequency of 3.5 GHz, where the qubit energy is well below the thermal energy. The unit cell constitutes the core building block of a full-scale silicon quantum computer, and satisfies layout constraints required by error correction architectures. Our work indicates that a spin-based quantum computer could be operated at elevated temperatures in a simple pumped $^4$He system, offering orders of magnitude higher cooling power than dilution refrigerators, potentially enabling classical control electronics to be integrated with the qubit array.
Lower-twin-peak quasiperiodic oscillation coherence in x-ray binaries and matter stretched by tides falling onto a compact object

description: Low mass x-ray binaries (LMXBs), with either a neutron star (NS) or a black hole, show in their power spectra quasiperiodic oscillations (QPOs). Those at highest frequencies show up in pairs and are named twin peak high frequency QPOs (HF QPOs). Their central frequencies are typical of the orbital motion timescale close to the compact object. HF QPOs are believed to carry unique information on the matter moving in the extreme gravitational field around the compact object. In previous works we highlighted the work done by strong tides on clumps of plasma orbiting in the accretion disk as suitable mechanism to produce the HF QPOs. We showed that the upper of the twin peak HF QPOs seen in NS LMXBs could originate from the tidal circularization of the clump's relativistic orbit, while the lower HF QPO could come from the spiraling clump losing orbital energy. Here we focus on the tidal deformation of a magnetized clump of plasma once tides load energy on it. The likely evolution of the shape of the clump after tidal circularization of the orbit and its subsequent orbital evolution are investigated. In atoll NS LMXBs, a subclass of NS LMXBs less luminous than Z NS LMXBs, the lower HF QPO displays a characteristic behavior of its coherence $Q$ versus its central frequency $ν$. $Q$ keeps increasing over the range of frequencies $ν\sim$ 600-850 Hz and then drops abruptly at $ν\sim$ 900 Hz. We note, for the first time, that such behavior is reproduced by magnetized clumps of plasma stretched by strong tides and falling onto the NS on unstable orbits. We emphasize the overall behavior of the lower HF QPO coherence as candidate to disclose the innermost stable bound orbit predicted by the general relativity theory in the strong field regime.

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: The influence of antiadiabatic phonons on the temperature of superconducting transition is considered within Eliashberg - McMillan approach in the model of discrete set of (optical) phonon frequencies. A general expression for superconducting transition temperature $T_c$ is proposed, which is valid in situation, when one (or several) of such phonons becomes antiadiabatic. We study the contribution of such phonons into the Coulomb pseudopotential $μ^{\star}$. It is shown, that antiadiabatic phonons do not contribute to Tolmachev's logarithm and its value is determined by partial contributions from adiabatic phonons only. The results obtained are discussed in the context of the problem of unusually high superconducting transition temperature of FeSe monolayer on STO.

description: Numerically we simulate the short-time behaviour of the critical dynamics for the two dimensional Ising model and Potts model with an initial state of very high temperature and small magnetization. Critical initial increase of the magnetization is observed. The new dynamic critical exponent $θ$ as well as the exponents $z$ and $2β/ν$ are determined from the power law behaviour of the magnetization, auto-correlation and the second moment. Furthermore the calculation has been carried out with both Heat-bath and Metropolis algorithms. All the results are consistent and therefore universality and scaling are confirmed.

description: We study random lattice networks consisting of resistor like and diode like bonds. For investigating the transport properties of these random resistor diode networks we introduce a field theoretic Hamiltonian amenable to renormalization group analysis. We focus on the average two-port resistance at the transition from the nonpercolating to the directed percolating phase and calculate the corresponding resistance exponent $ϕ$ to two-loop order. Moreover, we determine the backbone dimension $D_B$ of directed percolation clusters to two-loop order. We obtain a scaling relation for $D_B$ that is in agreement with well known scaling arguments.

description: Within the scope of a GSTP project, a Belgian-German research team performed experiments and simulations to characterise the behaviour of a liquid cooling film and to provide benchmark data for simulation models. The experiments were performed at DLR\'s M11.1 air vitiator test facility in Lampoldshausen, Germany. Ethanol was used as film coolant. Apart from being a potential renewable hydrocarbon fuel, ethanol is a suitable substitute fluid for monomethyl-hydrazine, which it is currently being used as propellant and film coolant in small liquid rocket engines. Compared to the situation in a real rocket engine, the experiment was designed to simplify the boundary conditions for the simulations by avoiding chemical reactions of the film with the hot gases as far as possible and to limit the phenomena subject to investigation to heat and mass transfer effects of a liquid cooling film subjected to heating and shear forces. The experimental setup used a planar film injector in a rectangular hot gas duct. Additionally to measurements of the pressure and temperature of the fluids at inlet and outlet of the test section, thermocouples were installed in the film cooled channel wall to provide information on the axial evolution of the film cooling efficiency. Furthermore, the channel provides optical access for nonintrusive measurement techniques. The von-Karman-Institute used this access to apply laser-based measurements of the temperature of the liquid film. DLR used a dedicated Background-Oriented Schlieren (BOS) technique to provide additional information on the evolution of the film thickness. Several tests have been performed in spring 2019. The test data have been analysed and are currently being used to benchmark simple engineering models as well as high-fidelity CFD models to predict the behaviour of liquid cooling films in rocket engines.

description: To systematically review the effectiveness and harms of interventions to promote resistance and resilience regarding mental health and occupational stress issues among emergency medical service (EMS) clinicians. We registered the systematic review prospectively on PROSPERO (CRD42023465325). We searched Medline, Embase, CENTRAL, CINAHL, ClinicalTrials.gov, journals, and websites for studies published from January 1, 2001, through June 30, 2024. We conducted duplicate screening of titles and abstracts followed by full texts of potentially relevant abstracts. We included studies of EMS clinicians in high-income countries that evaluated interventions targeting resistance or resilience regarding mental health or occupational stress issues. We assessed the risk of bias and evaluated strength of evidence (SoE) using standard methods. We included seven studies (one randomized controlled trial, one controlled trial with a waitlist control, four pre-post studies, and one prospective cohort [single group] study) that evaluated a total of 425 EMS clinicians. We deemed five of the seven studies to have high risk of bias, one moderate risk, and one low risk. No meta-analysis was feasible because of heterogeneity in the interventions evaluated across studies. Mindfulness-building interventions targeting resistance and resilience among EMS clinicians were associated with reduced burnout at up to 6 months of follow-up (low SoE). The evidence was insufficient regarding the impacts of interventions targeting both resistance and resilience on anxiety and depression. No conclusions are possible for resistance-only or resilience-only interventions. No studies reported on the effectiveness of any interventions in reducing hospitalizations, post-traumatic stress disorder, substance use, suicidality, or withdrawals from the workforce. No studies reported on unintended harms of interventions. Given the sparse evidence identified in this systematic review, evidence-based options to improve mental health outcomes for EMS clinicians are very limited. Future research is urgently needed to inform strategies to address the many mental health and occupational stress issues that face the EMS clinician workforce.

description: We present the analysis of the muon events with all muon multiplicities collected during 21804 hours of operation of the first LVD tower. The measured angular distribution of muon intensity has been converted to the `depth -- vertical intensity' relation in the depth range from 3 to 12 km w.e.. The analysis of this relation allowed to derive the power index, $γ$, of the primary all-nucleon spectrum: $γ=2.78 \pm 0.05$. The `depth -- vertical intensity' relation has been converted to standard rock and the comparison with the data of other experiments has been done. We present also the derived vertical muon spectrum at sea level.

description: This thesis examined the genetics of a group of chronic blood cancers, know as the myeloproliferative neoplasms (MPN). MPN cause abnormalities in the bone marrow and overproduction of cells in the blood. This study focused on a gene called SH2B3. Whilst some individuals with MPN have mutations in this gene, many of these mutations have not been established as a cause for the cancer. Through analysing cells, mice, and humans with SH2B3 mutations, this research demonstrated that some SH2B3 mutations are inherited, common within the general population, and can result in higher blood counts and an MPN.

description: In this paper, a direct approach is presented to tackle the multi-impulse rendezvous problem considering the impulse limit. Particularly, the standard Lambert problem is extended toward several consequential orbit transfers for the rendezvous problem. A number of different evolutionary algorithms are taken into consideration. It is shown that the proposed approach can lead to the optimal multi-impulse transfer maneuver that has the minimum amount of fuel similar to the traditional two-impulse transfer without violating the impulse limitation. Results also indicate that the approach is efficient even when the number of stages increases due to lower impulse limitations.

FLIGHT CONTROL

description: CALLISTO is an innovative project jointly led by CNES, JAXA and DLR with the objective to demonstrate the reusability of a small scale Vertical Take-off / Vertical Landing rocket. The control is performed through different kinds of actuators depending on the flight phase, including a gimballed engine with thrust modulation, a Reaction Control System (RCS) with 4 thrusters and 4 deployable fins. Two full scale missions are investigated: a so-called \"Power Tilt-Over\" (PTO) trajectory targeting a landing site close to the launch pad and including a return boost maneuver after the ascending phase, and a so-called \"Down Range\" (DR) trajectory targeting an off-shore landing platform. The wide range of flight conditions from take-off to landing and the targeted maneuvers lead to a vehicle that may be unsteady and nonlinear. At this stage of the project, ArianeGroup is in charge of designing the control law for the tilt-over maneuver, the back boost, the braking boost, the ballistic flight and the aerodynamic flight. This paper focuses on the studies carried out for the tilt-over maneuver. With high demands on agility and with a rate limited Thrust Vector Control (TVC), unstable pilot-induced oscillations (PIO) may occur during this phase. Based on a nonlinear frequential analysis and a temporal analysis, the effects of these oscillations and a solution to avoid them will be introduced.

description: DNNs have been quickly and broadly exploited to improve the data analysis quality in many complex science and engineering applications. Today's DNNs are becoming deeper and wider because of increasing demand on the analysis quality and more and more complex applications to resolve. The wide and deep DNNs, however, require large amounts of resources, significantly restricting their utilization on resource-constrained systems. Although some network simplification methods have been proposed to address this issue, they suffer from either low compression ratios or high compression errors, which may introduce a costly retraining process for the target accuracy. In this paper, we propose DeepSZ: an accuracy-loss bounded neural network compression framework, which involves four key steps: network pruning, error bound assessment, optimization for error bound configuration, and compressed model generation, featuring a high compression ratio and low encoding time. The contribution is three-fold. (1) We develop an adaptive approach to select the feasible error bounds for each layer. (2) We build a model to estimate the overall loss of accuracy based on the accuracy degradation caused by individual decompressed layers. (3) We develop an efficient optimization algorithm to determine the best-fit configuration of error bounds in order to maximize the compression ratio under the user-set accuracy constraint. Experiments show that DeepSZ can compress AlexNet and VGG-16 on the ImageNet by a compression ratio of 46X and 116X, respectively, and compress LeNet-300-100 and LeNet-5 on the MNIST by a compression ratio of 57X and 56X, respectively, with only up to 0.3% loss of accuracy. Compared with other state-of-the-art methods, DeepSZ can improve the compression ratio by up to 1.43X, the DNN encoding performance by up to 4.0X (with four Nvidia Tesla V100 GPUs), and the decoding performance by up to 6.2X.

description: Wave propagation through waveguides, quantum wires or films with a modest amount of disorder is in the semi-ballistic regime when in the transversal direction(s) almost no scattering occurs, while in the long direction(s) there is so much scattering that the transport is diffusive. For such systems randomness is modelled by an inhomogeneous density of point-like scatterers. These are first considered in the second order Born approximation and then beyond that approximation. In the latter case it is found that attractive point scatterers in a cavity always have geometric resonances, even for Schrödinger wave scattering. In the long sample limit the transport equation is solved analytically. Various geometries are considered: waveguides, films, and tunneling geometries such as Fabry-Pérot interferometers and double barrier quantum wells. The predictions are compared with new and existing numerical data and with experiment. The agreement is quite satisfactory.

We study the body-centered solid-on-solid model on a square lattice with an enhanced uniaxial interaction range to test the stability of the so-called stochastic FRE point where the model maps exactly onto one dimensional Kardar-Parisi-Zhang type growth and the local ECS is simple. The latter is unstable. The generic ECS contains first-order ridges extending into the rounded part of the ECS, where two rough orientations coexist and first-order faceted to rough boundaries terminating in Pokrovsky-Talapov type end points.

Role of Symmetry in Raman Spectroscopy of Unconventional Superconductors

description: The role of symmetry of the inelastic light scattering amplitude, the superconducting energy gap, and the underlying Fermi surface manifold on the Raman spectra of unconventional superconductors is discussed in detail. Particular emphasis is placed on both single and bi-layer superconductors. It is found that the $B_{1g}$ channel may be the most sensitive to doping due to the role of the Van Hove singularity. Lastly the effects of both disorder and spin fluctuations are considered. The theory imposes strong constraints on both the magnitude and symmetry of the energy gap for the bi-layer cuprates, indicating that a nearly identical energy gap of $d_{x^{2}-y^{2}}$ symmetry provides a best fit to the data.

BOUNDARY LAYERS

description: The resonance of thermal lags of solid fuel with heat transfer oscillations in the boundary layer flow is the primary mechanism of exciting low frequency instability (LFI) in hybrid rocket combustion. Recent studies reported that swirl injection seems to stabilize combustion by suppressing boundary layer oscillations. This study focused on the experimental investigation of how the boundary layer is perturbed and it leads to the LFI. Also the appearance of temporal stabilization of combustion between two consecutive LFIs was investigated in terms of boundary layer oscillation. Special attentions were also made to monitor the overall behavior of oscillating boundary layer and the occurrence of the LFI as swirl intensity increased. Fluctuating boundary layer was successfully captured by visualized images and POD (Proper Orthogonal Decomposition) analysis. In the results, oscillating boundary layer became stabilized as the swirl intensity increases. And the coupling strength between high frequency p\', q\' diminished and periodical amplification of RI (Rayleigh Index) with similar frequency band of thermal lag was also decayed. Results confirmed that oscillating axial boundary layer triggered by periodic coupling of high frequency p\', q\' is the primary mechanism to excite thermal resonance with thermal lag characteristics of solid fuel. Numerical simulation also confirmed that transitioning to a positive coupling of high frequency p\', q\' is the mechanism responsible for exciting boundary layer oscillation.

description: A nonrigid rotor model is developed from the two-parameter quantum algebra $U_{qp}({\rm u}_2)$. [This model presents the $U_{qp}({\rm u}_2)$ symmetry and shall be referred to as the qp-rotor model.] A rotational energy formula as well as a qp-deformation of E2 reduced transition probabilities are derived. The qp-rotor model is applied (through fitting procedures) to twenty rotational bands of superdeformed nuclei in the $A \sim 130$, 150 and 190 mass regions. Systematic comparisons between the qp-rotor model and the q-rotor model of Raychev, Roussev and Smirnov, on one hand, and a basic three-parameter model, on the other hand, are performed on energy spectra, on dynamical moments of inertia and on B(E2) values. The physical signification of the deformation parameters q and p is discussed.

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We study a one-dimensional model which undergoes a transition between an active and an absorbing phase. Monte Carlo simulations supported by some additional arguments prompted as to predict the exact location of the critical point and critical exponents in this model. The exponents $δ=0.5$ and $z=2$ follows from random-walk-type arguments. The exponents $β= ν_{\perp}$ are found to be non-universal and encoded in the singular part of reactivation probability, as recently discussed by H. Hinrichsen (cond-mat/0008179). A related model with quenched randomness is also studied.

description: This paper presents a numerical and experimental study of the aerodynamic characteristics of a VTOL micro air vehicle designed to fly on Mars. A blade airfoil is optimized for compressible and ultra-low Reynolds number flows. It is evaluated using unsteady laminar Navier-Stokes simulations. Isolated and coaxial rotors are designed using a free wake lifting line method and are evaluated using NavierStokes solvers. Optimized rotors are evaluated experimentally in the ONERA\'s low pressure tank, recreating Martian atmosphere. A set-up developed by ISAE-SUPAERO provides thrust and torque measurements, up to blade tip transonic flow conditions.

description: An effective field theoretic description of $ν=1$ bilayer electron systems stabilized by Coulomb repulsion in a single wide quantum well is examined using renormalization group techniques. The system is found to undergo a crossover from a low temperature strongly correlated quantum Hall state to a high temperature compressible state. This picture is used to account for the recent experimental observation of an anomalous transition in bilayer electron systems (T. S. Lay, {\em et al.} Phys. Rev. B {\bf 50}, 17725 (1994)). An estimate for the crossover temperature is provided, and it is shown that its dependence on electron density is in reasonable agreement with i the experiment.

description: Launched in October 2018, the ESA/JAXA BepiColombo mission shall arrive at Mercury in late 2025. The modular spacecraft consists of two scientific Mercury orbiters and a cruise module. Challenges for GNC design and operations include electric propulsion usage in cruise, the capability to deal with several S/C configurations, and strict attitude and solar array pointing constraints owing to the harsh thermal environment. This paper focuses on the return on experience after completion of in-orbit commissioning and the first electric propulsion thrust arc, in view of the mission\'s specific GNC challenges.
Parallel Attention Mechanisms in Neural Machine Translation

description: Recent papers in neural machine translation have proposed the strict use of attention mechanisms over previous standards such as recurrent and convolutional neural networks (RNNs and CNNs). We propose that by running traditionally stacked encoding branches from encoder-decoder attention- focused architectures in parallel, that even more sequential operations can be removed from the model and thereby decrease training time. In particular, we modify the recently published attention-based architecture called Transformer by Google, by replacing sequential attention modules with parallel ones, reducing the amount of training time and substantially improving BLEU scores at the same time. Experiments over the English to German and English to French translation tasks show that our model establishes a new state of the art.

Branching Fractions for $ψ(2S) to γη'$ and $γη$

description: We report the first measurements of the branching fractions: $B(ψ(2S) -> γη') = (1.54 \pm 0.31 \pm 0.23) x 10^{-4}$ and $B(ψ(2S) -> γη) = (0.53 \pm 0.31 \pm 0.08) x 10^{-4}$. The $ψ(2S)$ to $γη'$ result is consistent with expectations of a model that considers the possibility of $η' - η$ mixing. The ratio of the $ψ(2S)$ to $γη'$ and $ψ(2S)$ to $γη$ rates is used to determine the pseudoscalar octet-singlet mixing angle.

description: Hyperfine interactions in the light meson and baryon sectors are generalized to the charm and bottom systems. It is pointed out that an attempt to increase the value of the wave function at the origin to account for the unusual ratio of $Λ_{b}$ to the $B^0$ lifetimes could spoil the good agreement among the baryon and meson hyperfine mass-splitting. Including spin effects and taking phase space differences into account we predict that the decay rate of the $Λ_{b}$ can be increased relative to that of the $B^0$ meson by about 7%.

Die Daten wurden mittels einer Online-Umfrage und eines vordefinierten Fragebogens gesammelt und anschließend durch Reliabilitätsanalysen, Korrelationsanalysen und lineare Regressionen statistisch ausgewertet. Die Analyse zeigt, dass CSR einen maßgeblichen Einfluss auf Einstellungen und Verhaltensweisen hat, insbesondere in Bezug auf Umweltschutz, soziale Verantwortung und ethische Ziele. Unterschiede in der Wahrnehmung von CSR basierend auf Geschlecht und Alter zeigen die Notwendigkeit weiterer Untersuchungen. CSR-Maßnahmen stärken die Zufriedenheit der Geschäftspartner und fördern die langfristige Zusammenarbeit. Die Ergebnisse bestätigen den positiven Einfluss von CSR auf Kund*innenbindung, -zufriedenheit, -vertrauen und Unternehmensreputation. Unternehmen sollten CSR als integralen Bestandteil ihrer Strategie betrachten, transparent kommunizieren und zielgruppenspezifische Ansätze verfolgen. Die Studie liefert theoretische Erkenntnisse sowie praktische Anleitungen für nachhaltige und sozial verantwortliche Geschäftsstrategien im B2B-Bereich, insbesondere im DACH-Raum.
description: This master's thesis examined the significance of corporate social responsibility (CSR) for cooperation between companies and their business partners in the B2B sector. The data was collected using an online survey and a predefined questionnaire and then statistically analyzed using reliability analyses, correlation analyses and linear regressions. The analysis shows that CSR has a significant influence on attitudes and behaviors, especially with regard to environmental protection, social responsibility and ethical goals. Differences in the perception of CSR based on gender and age show the need for further research. CSR measures strengthen the satisfaction of business partners and promote long-term cooperation. The results confirm the positive influence of CSR on customer loyalty, satisfaction, trust and corporate reputation. Companies should consider CSR as an integral part of their strategy, communicate it transparently and pursue target group-specific approaches. The study provides theoretical insights as well as practical guidance for sustainable and socially responsible business strategies in the B2B sector, especially in the DACH region.
