Authors: Xue Xiaorui , Zhou Jiaqi , Hao Xintai , Jia Shaokui , Zeng Qingrui , Ren Xueguang 
Published: September 2024

The three-body fragmentation dynamics of benzene trications C6H63+ induced by 200 eV electron-impact produced by a photoemission cathode is investigated. All three fragment ions are detected in coincidence, and their momentum vectors are determined by employing a COLTRIMS reaction microscope. The detailed kinematical information of three deprotonation fragmentation channels of H+ + C3H2+ + C3H3+, H+ + C2H3+ + C4H2+, and H+ + C2H2+ + C4H3+ are obtained. By analyzing the momentum and energy correlation spectra among all the three fragment ions, we find that all the three channels are primarily generated by sequential fragmentation processes. Each channel has two deprotonation pathways, corresponding to proton emission in the first or second step of sequential fragmentation, respectively. These results provide insight into the mechanisms and dynamics of deprotonation and ring-breaking reactions in the three-body fragmentation processes of aromatic ring molecules.
Academic voice in the rhetorical construction of author identity
Authors: Mu Congjun 
Published: September 2024

Abstract
This paper compares the linguistic features contributing to the construction of academic voice in English, Chinese
and Translation corpora consisting of 180 research article introductions (RAIs) in the fields of biology, geology, and technology.
The study reveals significant differences in the strategies for constructing academic voice across languages. In comparison to the
English Corpus, the Translation Corpus exhibits higher or nearly equal normalized frequencies of certain linguistic features, such
as hedges, first-person pronouns, and passivizations. This pattern may suggest that Chinese authors project a less confident, less
committed, and less interactive voice in academic English discourse. Moreover, the uncritical academic voice that emphasizes
authority in Chinese-authored English RAIs may be attributed to their mother language background. Finally, we discuss the
implications of this study for multilingual professional writing and the teaching of academic writing within the paper.

Published: September 2024

Abstract
Providing basic health services to nomadic populations is challenging mainly because of their mobility affecting geographical access to essential services but also due to their particular cultural habits and beliefs, influencing health intervention acceptance. The strategy of joint human and animal health campaigns applied in Chad for over 30 years has helped to improve coverage of childhood and livestock vaccination and increased access to disease prevention. The campaigns are organized by the Chadian ministries for public health and livestock, supported by the Swiss Tropical and Public Health Institute (Swiss TPH) and its local partners. The use of synergies across sectors intends to reduce costs compared to independent sectoral interventions. The gain lies not only in shared logistics but also in better trust in essential services by pastoralists. Planning of joint interventions should start with a careful assessment of the context through a transdisciplinary approach identifying possible access barriers. This allows multidisciplinary development of mitigation measures such as a locally adapted awareness strategy. The multi-disciplinary approach also provides information on the seasonal movements of the different pastoral groups, which is crucial for the timing and location of interventions. Administrative and technical preparation of the field visits needs concerted efforts by all ministries and partners involved to maximize the benefits. To facilitate the uptake and sustainability of joint campaigns in Chad, the involved partners together developed an implementation guide based on their long-standing experience. This case report draws on this guiding document and showcases it for other actors interested in implementing similar One Health strategies.

Theoretical investigation of decoherence channels in athermal phonon sensors
Authors: Harrelson Thomas F , Hajar Ibrahim , Ashour Omar A , Griffin Sinéad M 
Published: September 2024

Abstract
The creation and evolution of nonequilibrium phonons is central in applications ranging from cosmological particle searches to decoherence processes in qubits. However, the fundamental understanding of decoherence pathways for athermal phonon distributions in solid-state systems remains an open question. Using first-principles calculations, we investigate the primary decay channels of athermal phonons in two technologically relevant semiconductors—Si and GaAs. We quantify the contributions of anharmonic, isotopic, and interfacial scattering in these materials. From this, we construct a model to estimate the thermal power in a readout scheme as a function of time. We discuss the implication of our results on noise limitations in current phonon sensor designs and strategies for improving coherence in next-generation phonon sensors.
Adsorption of Ag, Au, Cu, and Ni on MoS2: theory and experiment

Published: September 2024

Abstract
Here, we present results of a computational and experimental study of adsorption of various metals on MoS2. In particular, we analyzed the binding mechanism of four metallic elements (Ag, Au, Cu, Ni) on MoS2. Among these elements, Ni exhibits the strongest binding and lowest mobility on the surface of MoS2. On the other hand, Au and Ag bond very weakly to the surface and have very high mobilities. Our calculations for Cu show that its bonding and surface mobility are between these two groups. Experimentally, Ni films exhibit a composition characterized by randomly oriented nanoscale clusters. This is consistent with the larger cohesive energy of Ni atoms as compared with their binding energy with MoS2, which is expected to result in 3D clusters. In contrast, Au and Ag tend to form atomically flat plateaued structures on MoS2, which is contrary to their larger cohesive energy as compared to their weak binding with MoS2. Cu displays a surface morphology somewhat similar to Ni, featuring larger nanoscale clusters. However, unlike Ni, in many cases Cu exhibits small plateaued surfaces on these clusters. This suggests that Cu likely has two competing mechanisms that cause it to span the behaviors seen in the Ni and Au/Ag film morphologies. These results indicate that calculations of the initial binding conditions could be useful for predicting film morphologies. In addition, out calculations show that the adsorption of adatoms with odd electron number like Ag, Au, and Cu results in 100% spin-polarization and integer magnetic moment of the system. Adsorption of Ni adatoms, with even electron number, does not induce a magnetic transition.
Nonlinear electronic devices on single-layer CVD graphene for thermistors
Authors: Behera Saraswati 
Published: September 2024

Abstract
In this article, we present simple, cost-effective, passive (non-gated) electronic devices based on single-layer (SL) chemical vapor deposited (CVD) graphene that show nonlinear and asymmetric current–voltage characteristics (CVCs) at ambient temperatures. Al2O3–Ti–Au contacts to graphene results in a nonlinear resistance to achieve nonlinearity in the CVC. Upon transfer to polyethylene terephthalate, the CVD-grown SL graphene shows mobility of 6200 cm2 V−1 S−1. We have observed both thermoelectric effect and thermoresistive sensing in the fabricated devices such as voltage and temperature concerning change in electronic power and resistance through asymmetric and nonlinear CVC. The device is stable both at low and high voltages (±200 mV to ±4 V) and temperatures (4 K – 300 K). Graphene-based thermosensing devices can be ultra-thin, cost-effective, non-toxic/organic, flexible, and high-speed for integration into future complementary metal-oxide semiconductor (CMOS) interface, and wearable self-power electronics. A strong negative temeperature coefficent of resistance is demonstrated in the realized nonlinear graphene-integrated resistors for its application in NTC thermistors.
Chiral edge states and direct edge-to-edge transport in a bosonic magnetic ladder
Authors: Zhang Ai-Xia , Qin Ya-Hui , Gao Yun-Huan , Yuan Yi-Qing , Xue Ju-Kui 
Published: September 2024

Abstract
Three-legged magnetic ladder reproduces the main features of two-dimensional Hofstadter butterfly spectrum and the related Chern insulating phases with typical topological edge states, providing new opportunity to study novel quantum states and chiral physics. Here, we propose an efficient scheme to detect various edge states and realize edge-to-edge transport in a three-legged bosonic magnetic ladder. Under the mean field approximation, the eigenstates, chiral edge-state dynamics, and edge-to-edge transport in the system are studied. The energy spectrum and the eigenstates of the system are presented, and both bulk and edge states are obtained, depending on the energy spectrum of the system. The existence of rich edge states (including symmetric and unsymmetric edge states) provides the evidence for realizing the topological transport in the system. Furthermore, chiral edge-state dynamics is excited by applying a weak linear external force, reproducing the underlying eigenstates dynamically, offering a robust way to detect the edge states of the system. Particularly, direct edge-to-edge transport is observed which can be identified by the observables (spin polarization, spin tensor, and chiral currents). The reversal of chiral currents induces the edge-to-edge transport. The edge-to-edge transport time can be manipulated by adjusting the external force and magnetic field. We provide a robust and efficient atomic transport scheme with potential applications in manipulating topological quantum transport and storing quantum states in the ultracold atomic system.
Shubnikov–de Haas effect in the Falicov–Kimball model: strong correlation meets quantum oscillation
Authors: Yang Wei-Wei , Luo Hong-Gang , Zhong Yin 
Published: September 2024

Abstract
We present a comprehensive investigation of quantum oscillations (QOs) in the strongly-correlated Falicov-Kimball model (FKM). The FKM is a particularly suitable platform for probing the non-Fermi liquid (NFL) state devoid of quasiparticles, affording exact Monte Carlo simulation across all parameter spaces. In the high-correlation regime, we report the presence of prominent QOs in magnetoresistance and electron density at low temperatures within the phase separation state. The frequency behavior of these oscillations uncovers a transition in the Fermi surface as electron density diminishes, switching from hole-like to electron-like. Both types of Fermi surfaces are found to conform to the Onsager relation, establishing a connection between QOs frequency and Fermi surface area. Upon exploring the temperature dependence of QOs amplitude, we discern a strong alignment with the Lifshitz-Kosevich (LK) theory, provided the effective mass is suitably renormalized. Notwithstanding, the substantial enhancement of the overall effective mass results in a notable suppression of the QOs amplitude within the examined temperature scope, a finding inconsistent with Fermi liquid predictions. For the most part, the effective mass diminishes as the temperature increases, but an unusual increase is observed at the proximity of the second-order phase transition instigated by thermal effects. As the transition ensues, the regular QOs disappear, replaced by irregular ones in the NFL state under a high magnetic field. We also uncover significant QOs in the insulating charge density wave state under weak interactions (

), a phenomenon we elucidate through analytical calculations. Our findings shed light on the critical role of quasiparticles in the manifestation of QOs, enabling further understanding of their function in this context.
Regularity and uniqueness of solutions for compressible non-newtonian MHD equations with variable electrical conductivity and energy effects
Authors: Díaz Palencia José Luis 
Published: September 2024

Abstract
This paper examines the existence, uniqueness, and regularity of solutions for a system of compressible non-Newtonian magnetohydrodynamics (MHD) equations with variable electrical conductivity and considering the energy equation. We establish the necessary conditions on fluid properties, external forces, and initial and boundary conditions to ensure the well-posedness of the system. Our results demonstrate the existence of regular solutions in appropriate functional spaces, the uniqueness of these solutions, and their higher regularity under smooth initial and boundary conditions. These findings provide a mathematical baseline for the study of complex interactions in compressible non-Newtonian MHD flows, and particularly the findings can be considered to support more accurate numerical simulations concerning a physical situation as well as deeper analytical solutions.
Radiation influence on planar reconfigurable field effect transistor low noise amplifier performance
Authors: P Rajendiran , R Srinivasan 
Published: September 2024

Abstract
Many novel devices have been proposed in the literature to mitigate the short channel effect and the reconfigurable FET (RFET) is one of them. The circuits based on new devices need to be investigated when they are introduced. This work has two parts: (i) designing cascoded RFET low noise amplifiers (LNA) and their performance analysis; and (ii) single-event performance analysis of RFET-LNAs. The designed LNA has a gain of 12 dB and a noise figure of 2.42 dB. The device in the common gate configuration mode is more susceptible to heavy ion radiation and collects more charge (QC) compared to the device in the common source configuration mode. Through temporal and frequency analysis, the irradiation disturbance is examined. In the temporal analysis, the collected charge (QC) is used as a metric, and the spectrogram is used in the frequency analysis.
Study of doping effect of Cd on ZrO2 nanostructures for gas sensing applications
Authors: Hemalatha E , Gopalakrishnan N 
Published: September 2024

Abstract
Here, we enforced the conventional precipitation approach to yield pure and cadmium doped (3% and 8%) ZrO2 powder, to examine the gas sensing proficiency of Zirconium metal oxide. Drop casting mechanism is hired for the formation of pure and cadmium doped ZrO2 films. The x-ray diffraction (XRD) outcomes recommended that the prepared pure and cadmium doped ZrO2 powder samples are pure with no subordinate phase, but slight shift in peaks were detected. Scanning Electron Microscope (SEM) portrait substantiates the uniform spherical like morphology of the samples. The Current Voltage (I-V) study affirms the good conducting nature of the samples. The photoluminescence (PL) inspection, confirms that the oxygen vacant spots are present in the processed samples. The UV-Diffuse Reflectance Spectra validates the decrement of band gap of the prepared samples with rise in dopant concentration. The gas sensing capabilities of the drop casted samples were examined for different gas concentrations of reducing gases like ammonia, acetone, ethanol, formaldehyde and xylene at 120 °C. From the output data, we interpreted that the prepared samples show favourable response towards the target gas, explicitly the 8% cadmium doped sample shows 39% of an extreme response towards ammonia gas, then 34%, 25%, 20% and 18% towards xylene, acetone, ethanol and formaldehyde respectively. Likewise, it also accomplishes an expeditious response time (RST) of about 81s and recovery time (RCT) of about 85 s towards ammonia gas among all samples. Thus, we resolved that the inclusion of cadmium content stacks up the gas sensing adaptability of the zirconium metal oxide.
A PAge-like Unified Dark Fluid model
Authors: Wang Junchao , Huang Zhiqi , Yao Yanhong , Liu Jianqi , Huang Lu , Su Yan 
Published: September 2024

Abstract
The unified dark fluid model unifies dark matter and dark energy into a single component,
providing an alternative and more concise framework for interpreting cosmological observations. We
introduce a PAge-like Unified Dark Fluid (PUDF) model based on the PAge approximation (Huang
2020), which is parameterized by the age of the universe and an η parameter indicating the
deviation from Einstein-De Sitter Universe. The PUDF model shares many similar features of the
standard Lambda cold dark matter (ΛCDM) model and can effectively describe the large-scale
structure formation and late-time cosmic acceleration. We constrain the PUDF model with the Planck
2018 cosmic microwave background anisotropies, baryon acoustic oscillation measurements including
those from the most recent DESI 2024, the Pantheon+ sample of Type Ia supernovae, and the Cosmic
Chronometers compilation. Although the PUDF performs well in fitting all the cosmological
datasets, the joint analysis of the data still favors the ΛCDM model over the PUDF model,
according to the Bayesian evidence of model comparison.

Published: September 2024

Abstract

Objective. The phase of the electroencephalographic (EEG) signal predicts performance in motor, somatosensory, and cognitive functions. Studies suggest that brain phase resets align neural oscillations with external stimuli, or couple oscillations across frequency bands and brain regions. Transcranial Magnetic Stimulation (TMS) can cause phase resets noninvasively in the cortex, thus providing the potential to control phase-sensitive cognitive functions. However, the relationship between TMS parameters and phase resetting is not fully understood. This is especially true of TMS intensity, which may be crucial to enabling precise control over the amount of phase resetting that is induced. Additionally, TMS phase resetting may interact with the instantaneous phase of the brain. Understanding these relationships is crucial to the development of more powerful and controllable stimulation protocols. Approach. To test these relationships, we conducted a TMS-EEG study. We applied single-pulse TMS at varying degrees of stimulation intensity to the motor area in an open loop. Offline, we used an autoregressive algorithm to estimate the phase of the intrinsic µ-Alpha rhythm of the motor cortex at the moment each TMS pulse was delivered. Main results. We identified post-stimulation epochs where µ-Alpha phase resetting and N100 amplitude depend parametrically on TMS intensity and are significant versus peripheral auditory sham stimulation. We observed µ-Alpha phase inversion after stimulations near peaks but not troughs in the endogenous µ-Alpha rhythm. Significance. These data suggest that low-intensity TMS primarily resets existing oscillations, while at higher intensities TMS may activate previously silent neurons, but only when endogenous oscillations are near the peak phase. These data can guide future studies that seek to induce phase resetting, and point to a way to manipulate the phase resetting effect of TMS by varying only the timing of the pulse with respect to ongoing brain activity.
Understanding the High-energy Hardening in Cosmic Ray Spectra
Authors: Hu Haoran , Wu Juan 
Published: September 2024

Abstract
Recently, precise measurements on cosmic rays have been provided by various space experiments. A hardening at a few hundred GV has been observed in cosmic ray spectra both for primary and secondary particles. However, the reason for this hardening remains unclear. In this work, we employ the data measured by PAMELA, AMS02, ACE-CRIS and VOYAGER-1 to investigate this question. We study two different scenarios: the diffusion-reacceleration (DR) framework and the diffusion-convection (DC) framework. For each configuration, we investigate both the injection effects and the transport properties which may relate to the hardening. At the low-to-medium energy range, the diffusion slope δL are estimated to be 0.41 to 0.48. It is found that the value of δL estimated in the DR model is lower than that in the DC model. This infers that the reacceleration mechanism can result in steeper shapes in the (Li, Be, B)/C ratios than the convection process. At high energies, a variation in diffusion slope with Δδ ∼ −0.16 is favoured to explain the high-energy hardening structures observed in (Li, Be, B)/C ratios. Recent B/C data measured by DAMPE infers an even stronger high-energy diffusion break with Δδ ∼ −0.19.
Evaluating the Efficiency of CuInGaSe2 Based Solar Cells: CuSCN Hole Transport Layer (HTL) Effect

Published: September 2024

Abstract
Copper indium gallium disulfide (CuInGaSe2) or (CIGS) based solar cells are emerging solar cell structures that have attracted significant interest in recent years. In this research, a SCAPS-1D simulator was used to investigate the performance of the proposed CIGS based solar cell under the effect of a copper (I) thiocyanate (CuSCN) hole transport layer (HTL). Different photovoltaic parameters, such as the efficiency, short circuit current density (Jsc) and open-circuit voltage (Voc), are observed with respect to the doping concentration, temperature, and thickness. A comparative study is presented between a hole transport layer (HTL) and without an HTL. The simulation results demonstrate that the HTL has a significant impact and plays a major role in improving the performance of the proposed CIGS solar cell structure compared to that without the HTL. This research outlines a structured guide for both the manufacturing process and achievement of cost-effective, highly efficient solar cells.

Authors: Zheng Wenxiu , Chen Xu , Li Ting , Niu Tianlin , Wang Xiaodan , Zhao Yuwei 
Published: September 2024

Abstract
The adsorption characteristics of the lubricating oil near the solid surface play crucial roles in the lubricating performance. In this paper, the molecular dynamics simulation implemented by MS software was carried out to reveal the adsorption properties of different lubricants on Fe2O3 surfaces. Several kinds of lubricating oil molecules were employed, namely, n-eicosane, 2, 6, 11, 15-tetramethylhexadecane, 2-decyldecahydronaphthalene and tetradecylcyclohexane. The results show that 2, 6, 11, 15-tetramethylhexadecane and 2-decyldecahydronaphthalene are relatively more favorable as the lubricant components. This is because they both have relatively high adsorption density, low molecular diffusivity and large adsorption energy. These results can provide a theoretical basis for the selection of future lubricant components as well as lubricant performance enhancement for blending.
