Existential, locative and possessive predication in Kamas
Authors: Däbritz Chris Lasse , Wagner-Nagy Beáta 
Published: May 2024

Abstract
This paper describes and analyses existential, locative and possessive predications in Kamas. Starting from a
functional-semantic perspective, we show that the three types of predications share many features, but they also exhibit some
important differences. Given that two layers of Kamas can be distinguished, we demonstrate that the reactivated Kamas of the last
speaker, Klavdiya Plotnikova, exhibits some peculiarities which can be explained partly by Russian influence. The most important
result of the study is that the boundaries between the three predication types are rather fluid in Kamas, whereas the distinction
between affirmative and negative clauses is morphosyntactically unambiguously manifested. This polarity split, given that it is
seldom recognised in the general literature, may provide important implications for linguistic typology and theory.
Plasma in liquids induced modification of Cu surfaces
Authors: Pottkämper P , von Keudell A 
Published: May 2024

Abstract
Copper oxide surfaces are commonly used as the catalyst for the CO2 reduction reaction towards hydrocarbons. However, the lifetime of these catalyst surfaces is limited. In this paper, a method of production of copper oxides through in-liquid plasma is explored, which may be a suitable reactivation method in such applications. The influence of the plasma, ignited in distilled water, with copper and its oxides is monitored in − situ using infrared spectroscopy and ex-situ using scanning electron spectroscop and x-ray photoelectron spectroscopy of the samples. It is shown that the interaction of the plasma with the samples causes a reduction of the copper oxide on a fast time scale and an oxidation on a longer time scale. The formation of preferentially oriented copper nanocubes is observed.
Development of nickel vanadium-impregnated activated carbon nanocomposites for electrocatalytic conversion of furfural into fuels

Published: May 2024

Abstract
Furfural, derived from biomass, is crucial for achieving carbon neutrality through biomass utilization. It can be converted into furfuryl alcohol and other valuable components used in the chemical industry. Electrochemical methods offer improved selectivity in the conversion of furfural under mild conditions compared to traditional hydrogenation. This study investigates the electrocatalytic conversion of furfural using a hydrothermally synthesized nickel-vanadium-impregnated activated carbon catalyst. The developed catalysts were characterized by x-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy and x-ray photoelectron spectroscopy. The as-developed catalyst was used to synthesize electrodes for the electrochemical conversion of furfural. The behavior was investigated using electrochemical impedance spectroscopy and linear sweep voltammetry. The study optimized the Ni:V ratio, applied voltages, electrolyte molarity and reaction time and found that a Ni:V ratio of 1:1 resulted in maximum furfural conversion. The Ag/AgCl cathode at −0.9 V showed a low reaction rate, thus requiring higher voltages for efficient conversion. LC-UV-ESI MS analysis of the cathode half-reaction revealed the formation of a nitrogen-containing compound, likely stemming from the reaction between furfural and acetonitrile under the influence of the catalyst. This study demonstrates the effectiveness of NiV/AC catalysts in the electrocatalytic conversion of furfural, with a conversion rate of 90% and a faradaic efficiency of around 30% at −1.3 V. Furthermore, a plausible reaction mechanism was proposed.
Similarities and differences in the ordering at short and long ranges in a NaNbO3 based Pb-free smart system: a key to functional properties

The investigation of long-range structural phase transitions as a function of composition(x) using x-ray diffraction is complemented by short-range structural insights from Raman spectroscopy. The incorporation of BCT disrupts the delicate antiferroelectric ordering of NN and stabilizes various ferroelectric phases with increasing BCT content(x). At x = 0.10, the simultaneous presence of two ferroelectric phases viz., Pmc21 and Amm2, results in a threefold rise in remanent polarization compared to off-boundary compositions. The composition with higher BCT content (i.e.

This contrapositive behavior (i.e. hysteresis loop in a centrosymmetric structure) has been attributed to the correlations among local static polar distortions of rhombohedral type ascertained using Raman spectroscopy. The coexistence of two ferroelectric phases at room temperature(for x = 0.10) and a slim hysteresis loop (for

Diquark break-up jet effects on particle production in central Ar+Sc and Pb+Pb collisions at CERN SPS energies
Authors: Abdel-Waged Khaled , Felemban Nuha 
Published: May 2024

Abstract
We investigate the rapidity spectra of protons in central Ar+Sc and Pb+Pb collisions at Conseil Européen pour la Recherche Nucléaire (CERN) super proton synchrotron (SPS) energies, utilizing the HIJING code integrated with the advanced popcorn (AP) mechanism from PYTHIA6.4. We find that the standard HIJING/AP model is inadequate for fully capturing the proton rapidity distributions observed in these collisions. To overcome this, we focus on the leading diquark (LD) break-up component, distinguishing between diquark preserving and diquark breaking (DB) behaviors. Our analysis reveals that the suppressed DB component is essential for accurately describing the proton and neutron x

values consistent with experimental observations. By integrating the suppressed LD break-up mechanism, informed by pp and Be+Be collision data, we successfully replicate the proton rapidity spectra and also effectively capture the rapidity spectra of negative pions and charged kaons for the studied reactions. These outcomes underscore the critical role of the suppressed LD break-up component in elucidating the mechanisms of baryon production and stopping in heavy-ion collisions at CERN SPS energies.
Combining simulation and experimental data via surrogate modelling of continuum dislocation dynamics simulations

Published: May 2024

Abstract
Several computational models have been introduced in recent years to yield comprehensive insights into microstructural evolution analyses. However, the identification of the correct input parameters to a simulation that corresponds to a certain experimental result is a major challenge on this length scale. To complement simulation results with experimental data (and vice versa) is not trivial since, e.g. simulation model parameters might lack a physical understanding or uncertainties in the experimental data are neglected. Computational costs are another challenge mesoscale models always have to face, so comprehensive parameter studies can be costly. In this paper, we introduce a surrogate model to circumvent continuum dislocation dynamics simulation by a data-driven linkage between well-defined input parameters and output data and vice versa. We present meaningful results for a forward surrogate formulation that predicts simulation output based on the input parameter space, as well as for the inverse approach that derives the input parameter space based on simulation as well as experimental output quantities. This enables, e.g. a direct derivation of the input parameter space of a continuum dislocation dynamics simulation based on experimentally provided stress–strain data.

AbstractThe field of nanoscale magnetic resonance imaging (NanoMRI) was started 30 years ago. It was motivated by the desire to image single molecules and molecular assemblies, such as proteins and virus particles, with near-atomic spatial resolution and on a length scale of 100 nm. Over the years, the NanoMRI field has also expanded to include the goal of useful high-resolution nuclear magnetic resonance (NMR) spectroscopy of molecules under ambient conditions, including samples up to the micron-scale. The realization of these goals requires the development of spin detection techniques that are many orders of magnitude more sensitive than conventional NMR and MRI, capable of detecting and controlling nanoscale ensembles of spins. Over the years, a number of different technical approaches to NanoMRI have emerged, each possessing a distinct set of capabilities for basic and applied areas of science. The goal of this roadmap article is to report the current state of the art in NanoMRI technologies, outline the areas where they are poised to have impact, identify the challenges that lie ahead, and propose methods to meet these challenges. This roadmap also shows how developments in NanoMRI techniques can lead to breakthroughs in emerging quantum science and technology applications.
Superposition solitons for the mixed 4-coupled nonlinear Schrödinger equations
Authors: Zhang LingLing , Ye XueWei 
Published: May 2024

Abstract
In this paper, the mixed 4-coupled nonlinear Schrödinger equations with different nonlinear signs are studied to derive a new type of soliton solutions called the superposition soliton solutions. By using the Hirota method, we obtain the exact one-bright-three-superposition N-soliton solutions analytically. Notably, this kind of soliton solutions have not been researched in prior literature. Under certain conditions, the general mixed (bright-dark) soliton solutions can be obtained from our results such as all bright soliton solutions. In addition, the propagation characteristics, including elastic collision, time periodicity and soliton reaction, are displayed through graphic simulation. On this basis, the influence of various parameters on the phase, direction, and amplitude of soliton propogation is concluded. Finally, the asymptotic behaviors of 2, 3-soliton solutions are analyzed in detail.
High-precision two- and three- dimensional atom localization in a microwave and radio-frequency driven Δ∇ system
Authors: Thakur Himani , Dar Zubair Iqbal , Singh Mandeep , Arora Himani , Kaur Paramjit 
Published: May 2024

Abstract
We introduce a new approach for precise and high-resolution two-dimensional (2D) and three-dimensional (3D) atom localization in a four-level Δ∇ atomic system driven by microwave (M) and radio frequency (R) fields. In the proposed work, additional microwave and radio-frequency fields are utilized for an efficient control of the localization precision. Due to the spatially varying atom-field interaction, the probe susceptibility become position dependent and therefore, one can directly ascertain the position probability distribution of an atom by analyzing the probe spectra. The phase-sensitive property of the atomic system plays a significant role in substantially reducing the uncertainty associated with atom position measurements. We have studied the system behavior through the analysis of dressed states, which forms the basis for its physical interpretation. The increase in precision for measuring the atom’s position is a result of interference between one-photon excitation and the phase-dependent three-photon excitation arising from the closed interacting contour within the laser-driven atomic system, as demonstrated through both numerical calculations and qualitative analyses. The findings indicate that precise sub-wavelength atom localization can be attained by appropriately adjusting the system parameters. Also, the optimal adjustment of these parameters can lead to 100% probability of locating the atom at a particular position within 2D and 3D subspaces.
Application of multi-objective optimization genetic algorithm to design terahertz metamaterials with fano resonances
Authors: Qin Binyi , Li Yun , Liao Qitao , Qiu Jie , Yang Ruizhao , Zheng Jincun , Zhong Hesen 
Published: May 2024

Abstract
In the prosperous development of terahertz (THz) metamaterials, Fano resonances have gained attention due to their potential applications in ultrasensitive systems. The performance of Fano resonance is directly influenced by the geometrical parameters of the element structure. However, the traditional design rules for Fano resonances in metamaterials rely on an empirical trial-and-error strategy, necessitating significant effort to achieve optimal results. To address this issue, we propose a design method in this study that utilizes the finite integration technique in time domain (FITD) along with a multi-objective optimization genetic algorithm for the intelligent design of metamaterial structures exhibiting the Fano resonance phenomenon. The FITD method is primarily used to calculate the Fano resonance with different metamaterial geometric structure parameters, while the genetic algorithm efficiently selects the optimal solution. Our method, characterized by high efficiency and complete independence from prior knowledge, could offer a new design technique for metamaterials with specific functions, thereby contributing to the development of THz applications.
Atomic level mechanism of disorder-order transformation kinetics at nanoscale in FePt based systems
Authors: Kumar Shubham , Tiwari Atul , Gupta Mukul , Sharma Gagan , Srihari V , Gupta Ajay , Reddy V R , Gome Anil , Sharma Kavita 
Published: May 2024

Abstract
L10 ordered FePt is one of the most promising materials for spintronic and recording media applications. In the present work, the mechanism of L10 phase transformation in FePt based films with varying initial structures is examined at the nanoscale to understand the ordering process using synchrotron based GIXRD, MOKE, VSM, and techniques with sub nanometer depth selectivity like XRR and SIMS. Precisely controlled compositions of the films are deposited using magnetron sputtering. Rapid thermal annealing is used for post-deposition processing. It is evaluated experimentally that for a shorter annealing time of 70 s at 400 °C, besides volume diffusion, short circuit diffusion paths along the intercrystallite region owing to the presence of nanostructured grains play a dominant role in alloying behavior. A study of the L10 ordering process reveals the crucial role of film structure in controlling the transformation kinetics, texturing of nanograins, and magnetic coercivity. Diffusion studies disclose that type B diffusion kinetics is activated for the annealing time during which L10 transformation occurs in the films.
Gravitational radiation from eccentric binary black hole system in dynamical Chern-Simons gravity
Authors: Li Zhao , Qiao Jin , Liu Tan , Niu Rui , Hou Shaoqi , Zhu Tao , Zhao Wen 
Published: May 2024

Abstract
Dynamical Chern-Simons (DCS) gravity, a typical parity-violating gravitational theory, modifies both the generation and propagation of gravitational waves from general relativity (GR). In this work, we derive the gravitational waveform radiated from a binary slowly-rotating black hole system with eccentric orbits under the spin-aligned assumption in the DCS theory. Compared with GR, DCS modification enters the second-order post-Newtonian (2PN) approximation, affecting the spin-spin coupling and monopole-quadrupole coupling of binary motion. This modification produces an extra precession rate of periastron. This effect modulates the scalar and gravitational waveform through a quite low frequency. Additionally, the dissipation of conserved quantities results in the secular evolution of the semimajor axis and the eccentricity of binary orbits. Finally, the frequency-domain waveform is given in the post-circular scheme, requiring the initial eccentricity to be ≲ 0.3. This ready-to-use template will benefit the signal searches and improve the future constraint on DCS theory.
A Minkowski functional analysis of the Cosmic Microwave Background weak lensing convergence
Authors: Hamann Jan , Kang Yuqi 
Published: May 2024

Abstract
Minkowski functionals are summary statistics that capture the geometric and morphological properties of fields. They are sensitive to all higher order correlations of the fields and can be used to complement more conventional statistics, such as the power spectrum of the field. We develop a Minkowski functional-based approach for a full likelihood analysis of mildly non-Gaussian sky maps with partial sky coverage. Applying this to the inference of cosmological parameters from the Planck mission's map of the Cosmic Microwave Background's lensing convergence, we find an excellent agreement with results from the power spectrum-based lensing likelihood. While the non-Gaussianity of current CMB lensing maps is dominated by reconstruction noise, a Minkowski functional-based analysis may be able to extract cosmological information from the non-Gaussianity of future lensing maps and thus go beyond what is accessible with a power spectrum-based analysis. We make the numerical code for the calculation of a map's Minkowski functionals, skewness and kurtosis parameters available for download from https://github.com/Kang-Yuqi/MF_lensing.
LiteBIRD and CMB-S4 sensitivities to reheating in plateau models of inflation
Authors: Drewes Marco , Ming Lei , Oldengott Isabel 
Published: May 2024

Abstract
We study the sensitivity of LiteBIRD and CMB-S4 to the reheating temperature and the inflaton coupling in three types of plateau-potential models of inflation, namely mutated hilltop inflation, radion gauge inflation, and α-attractor T models. We first find relations between model parameters and CMB observables in all models. We then perform Monte Carlo Markov Chain based forecasts to quantify the information gain on the reheating temperature, the inflaton coupling, and the scale of inflation that can be achieved with LiteBIRD and CMB-S4, assuming a fiducial tensor-to-scalar ratio r̅ ∼ 0.02 and neglecting foreground contamination of the B-mode polarization spectrum. We compare the results of the forecasts to those obtained from a recently proposed simple analytic method. We find that both LiteBIRD and CMB-S4 can simultaneously constrain the scale of inflation and the reheating temperature in all three types of models. They can for the first time obtain both an upper and lower bound on the latter, comprising the first ever measurement of the big bang temperature. In the mutated hilltop inflation and radion gauge inflation models this can be translated into a measurement of the inflaton coupling in parts of the parameter space. Constraining this microphysical parameter will help to understand how these models of inflation may be embedded into a more fundamental theory of particle physics.

Abstract
The similar densities of dark matter and baryons in the universe imply that they may arise from the same ultraviolet model. B-Mesogenesis, which assumes dark matter is charged under the baryon number, attempts to simultaneously explain the origin of baryon asymmetry and dark matter in the universe. In particular, B-Mesogenesis may induce bottom-baryon decays into invisible or semi-invisible final states, which provide a distinctive signal for probing this scenario. In this work, we systematically study the invisible decays of bottom baryons into dark matter and the semi-invisible decays of bottom baryons into a meson or a photon together with a dark matter particle. In particular, the fully invisible decay can reveal the stable particles in B-Mesogenesis. Some QCD-based frameworks are used to calculate the hadronic matrix elements under the B-Mesogenesis model. We estimate the constraints on the Wilson coefficients or the product of some new physics couplings with the Wilson coefficients according to the semi-invisible and invisible decays of bottom baryons detectable at future colliders.

Abstract
A model for the pedestal density prediction based on neutral penetration combined with pedestal transport is presented. The model is tested against a pedestal database of JET-ILW Type I ELMy H-modes showing good agreement over a wide range of parameters both in standalone modelling (using the experimental temperature profile) and in full Europed modelling that predicts both density and temperature pedestals simultaneously. The model is further tested for ASDEX Upgrade and MAST-U Type I ELMy H-modes and both are found to agree with the same model parameters as for JET-ILW. The JET-ILW experiment where the isotope of the main ion is varied in a D/T scan at constant gas rate and constant
