Authors: Zhang Zhongding , Lu Datan , Ying Tingting , Li Shiting , Zhao Hua 
Published: November 2024

Abstract
Background Hemimasticatory spasm (HMS) is an uncommon movement disorder of the trigeminal motor rootlet characterized by unilateral, involuntary, and paroxysmal contractions of the muscles of mastication. The mechanisms for HMS are still unclear, and an efficient treatment strategy still needs to be developed. This study aims to investigate the clinical features and surgical treatment of HMS.
Methods Twelve patients with HMS were included in our study. The patient data regarding clinical characteristics, neuroimaging presentations, intraoperative findings, and treatment outcomes were analyzed retrospectively. Highly selective trigeminal motor root rhizotomy (HSTR) combined with microvascular compression was performed in nine cases with neurovascular conflict, whereas three patients without vascular compression underwent HSTR only.
Results Intraoperative findings showed that there were two patients with six branches, two patients with five branches, and the remaining patients with three to four branches of the trigeminal motor roots. Seven patients had two motor branches severed, three patients had one motor branch severed, and two patients each had three motor branches severed. Nine patients recovered uneventfully and showed no signs of spasms, and the remaining two patients experienced complete disappearance of symptoms within 3 months after surgery. In one patient, the symptoms disappeared immediately after surgery but recurred 2 years later.
Conclusion The surgical procedures of HSTR can significantly alleviate the clinical symptoms of patients with HMS without serious complications.

AbstractThe main objective of this research article is to examine the effect of intellectual capital (IC) and its dimensions on the financial performance (FP) of the Indian renewable energy industry, guided by the Resource-Based View (RBV). The study employed data from 36 solar and 39 wind sector companies for six years, from 2017 to 2022. Moreover, the modified value added intellectual coefficient (MVAIC) model was used to measure the company’s IC. Further, the paper uses panel data regression analysis to examine the above-mentioned objectives. The results showed that IC improves the earnings and profitability of solar sector companies, while for wind sector companies, it only helps boost their profitability. Contrary to the expectation, human capital efficiency (HCE) failed to show any effect on the FP of the Indian solar sector companies. However, HCE positively moderates the relationship between structural capital efficiency (SCE) and FP, as well as relational capital efficiency (RCE) and FP. For the wind sector companies, HCE significantly and positively affects the FP; however, HCE negatively moderates SCE and profitability while positively for capital employed efficiency (CEE) and FP. This research adds new data from an industry that has previously received little attention (i.e. Indian renewable energy industry), thus broadening the research on the relationship between IC and FP. Moreover, the study may provide in-depth insights into the MVAIC dimensions as it discovers the moderating effect of human capital in boosting the company’s FP.
Tornado scar on the Nullarbor Plain, Australia
Authors: Lipar Matej 
Published: November 2024

A newly discovered erosional scar on the Nullarbor Plain in southern Australia was analysed and hypothesised to be a consequence of a tornado event. The scar, identified using satellite imagery, stretches ~11 km in length and varies between 160 and 250 m in width, with notable cycloidal marks indicating activity of suction vortexes. The timing of the scar formation, constrained by Landsat and Sentinel imagery, is between 16 and 18 November 2022, coinciding with a significant weather event on 17 November 2022. The scar’s characteristics and the associated weather patterns strongly suggest it was formed by a tornado. Based on the scar’s dimensions and the pattern of cycloidal marks, the tornado’s strength is estimated to be within the F2 or even F3 category on the Fujita scale, with wind speeds likely exceeding 200 km h–1, moving in an eastward direction and swirling clockwise.
A noodle in a haystack: determining the conservation status of the rare and Data Deficient Ravensthorpe Range slider, Lerista viduata

Published: November 2024

Context One-seventh of the ~157,000 species assessed by the IUCN Red List of Threatened Species are Data Deficient (DD), with insufficient information to assess their extinction risk. Such a statistic is concerning from a conservation perspective because more than half are predicted to be threatened by extinction, yet they are generally neglected from conservation priority. Aims Here, we aimed to improve ecological knowledge, and inform the conservation status of, the DD Ravensthorpe Range slider (Lerista viduata), a historically rare skink confined to Western Australia’s Ravensthorpe Range. Methods A detailed framework was developed to improve data on attributes integral to the species’ IUCN Red List assessment (e.g. distribution, threats, population size): collation of historical records, fieldwork within and around its known range, preserved specimen analysis, on-ground and spatial analysis of threats, and inference from ecologically similar species. Key results We found that L. viduata is threatened under multiple IUCN Red List criteria (B1ab[i,ii,iii,v], B2ab[i,ii,iii,v], C2ab[ii], D2), and overall should be considered Critically Endangered. This status is based on its Extent of Occurrence (32 km2) being <100 km2, occurrence at one location (defined by the threat of fire), and an inferred continuing decline in its distribution and habitat parameters. The species’ small estimated population size (3,514–9,276 mature individuals) also renders it extinction prone. Conclusions We demonstrate that L. viduata, long perceived as DD, should be reclassified as Critically Endangered, and is of the utmost conservation concern. Implications Our study reiterates the need for DD species to receive greater consideration in conservation research and action.
Determining initial conditions for nonlinear hyperbolic equations with time dimensional reduction and the Carleman contraction principle
Authors: Dang Trong D , Nguyen Loc H , Vu Huong T T 
Published: November 2024

Abstract
This paper aims to determine the initial conditions for quasi-linear hyperbolic equations that include nonlocal elements. We suggest a method where we approximate the solution of the hyperbolic equation by truncating its Fourier series in the time domain with a polynomial–exponential basis. This truncation effectively removes the time variable, transforming the problem into a system of quasi-linear elliptic equations. We refer to this technique as the ‘time dimensional reduction method.’ To numerically solve this system comprehensively without the need for an accurate initial estimate, we used the newly developed Carleman contraction principle. We show the efficiency of our method through various numerical examples. The time dimensional reduction method stands out not only for its precise solutions but also for its remarkable speed in computation.
Coenhancement of optical transmission and Faraday effect with magnetic plasmonic nanopillars
Authors: Luo Peng , Wang Qiang , Wang Han 
Published: November 2024

Abstract
Coenhancement of optical transmission and the Faraday effect are always the goals to pursue for photoelectric devices, while the current research almost concentrated on the properties based on gratings and photonic crystal structures. Nanopillars (NPs) are structures with a relatively simple preparation that have been widely used in many fields, where the Faraday effect has been rarely studied. In this work, a Faraday rotator in the wavelength range of 500–800 nm is proposed based on bismuth–iron garnet (BIG) with magnetic plasmonic NPs structure, in which the hemispherical shaped silver covered on top and silica used as the substrate for enhancement effect. Through this rotator, two peak values for both Faraday rotation angle and transmittance can be achieved, no matter what the wavelength changes are. The transmittance, Faraday rotation angle, and figure of merit (FOM) can be controlled by tuning the thickness and lattice constant of the BIG NPs, the radius of the silver hemisphere, and the external magnetic field. Furthermore, the physics mechanism of the large Faraday effect and extraordinary optical transmission is explained by employing the electric field distribution diagrams. Finally, the optimized FOM simply can be raised to 0.9, achieving well overall performance in the visible light range. The results have certain values for achieving simpler and better performance of magneto-optical devices under visible wavelength range, such as optical isolators and magneto-optical sensors.

Abstract

Objective. The arrangement of chromosomes in the cell nucleus has implications for cell radiosensitivity. The development of new tools to utilize Hi-C chromosome conformation data in nanoscale radiation track structure simulations allows for in silico investigation of this phenomenon. We have developed a framework employing Hi-C-based cell nucleus models in Monte Carlo radiation simulations, in conjunction with mechanistic models of DNA repair, to predict not only the initial radiation-induced DNA damage, but also the repair outcomes resulting from this damage, allowing us to investigate the role chromosome conformation plays in the biological outcome of radiation exposure. Approach. In this study, we used this framework to generate cell nucleus models based on Hi-C data from fibroblast and lymphoblastoid cells and explore the effects of cell type-specific chromosome structure on radiation response. The models were used to simulate external beam irradiation including DNA damage and subsequent DNA repair. The kinetics of the simulated DNA repair were compared with previous results. Main results. We found that the fibroblast models resulted in a higher rate of inter-chromosome misrepair than the lymphoblastoid model, despite having similar amounts of initial DNA damage and total misrepairs for each irradiation scenario. Significance. This framework represents a step forward in radiobiological modeling and simulation allowing for more realistic investigation of radiosensitivity in different types of cells.
Statistical biases correction in channelized Hotelling model observers
Authors: Desponds Lionel 
Published: November 2024

Abstract

Objective. Channelized Hotelling model observers are efficient at simulating the human observer visual performance in medical imaging detection tasks. However, channelized Hotelling observers (CHO) are subject to statistical biases from zero-signal and finite-sample effects. The point estimate of the d′ value is also not always symmetric with exact confidence interval (CI) bounds determined for the infinitely trained CHO. A method for correcting these statistical biases and CI asymmetry is studied. Approach. CHO d′ values and CI bounds with hold-out and resubstitution methods were computed for a range of 200 × 200 pixels images from 20 to 10 000 images for 10, 40 and 96 channels from a set of 20 000 images with gaussian coloured simulated noise and simulated signal. The median of the non-central F cumulative distribution (F′), which is the CHO underlying statistical behaviour for the resubstitution method, was computed, and compared to d′ values and CI bounds. A set of experimental data was used to evaluate F′ median values. Main results. The F′ median allows to get accurate corrected simulated d′ values down to zero-signals. For small d′ values, the variation of d′ values with the inverse of number of images is not linear while the F′ median allows a good correction in such conditions. The F′ median is also inherently symmetric with regards to the CI. With experimental data, F′ median values in a range of about 1–10 d′ values were within −0.8% to 4.7% of linearly extrapolated values at an infinite number of images. Significance. The F′ median correction is an effective simultaneous correction of the zero-signal statistical bias and finite-sample statistical bias, and of CI asymmetry of CHO.

Published: November 2024

Abstract
In this paper, we address the optimal control problem in molecular systems, focusing on transitions within coherent states characterised by complex coefficients. Employing Hölder’s inequality, we establish a mathematical relationship between the energy requirement and the distance separating the initial and the target coherent states. A key part of our study is the application of this framework to the H2O molecule, specifically examining the local OH bond. Here, we demonstrate how energy requirements for the state transitions are influenced by the distance between these states. Furthermore, we investigate the effects of a heat bath coupled to the system, by analysing its impact on transferring the molecular system to different final coherent states. These coherent states are defined as almost eigenvectors of the Generalised Heisenberg Algebra (GHA) annihilation operator. By using the Perolomov approach, another type of coherent states for the Morse potential associated with the GHA can be constructed. By leveraging the GHA structure, we revisit and analyse Morse coherent states previously established for certain diatomic molecules, offering a deeper insight into the dynamics of state transitions under various conditions.

Published: November 2024

Abstract
Nanotechnology is an emerging field in the modern era, and nanotubes, tube-like structures derived from various materials, including carbon, silicon, and boron, are extensively used in nanosciences, particularly in medicine, energy, and the synthesis of new compounds. The physical stability and chemical properties of nanotubes are topics of significant interest due to their high impact. A topological index is an invariant numerical value associated with certain physicochemical properties and aids in exploring key insights into a chemical compound. In this paper, we compute several degree-based topological indices, including the first Zagreb, second Zagreb, multiplicative first Zagreb, multiplicative second Zagreb, hyper Zagreb, atom-bond connectivity, sum connectivity, and Sombor indices. We also calculate the related entropies for two silicon nanotubes. A numerical comparison of the different values of the indices above and a regression model is also established.
A novel multi-delay feedback digital chaos anti-degradation algorithm and its application in key generator

Published: November 2024

Abstract
Under conditions of finite accuracy, chaotic systems will exhibit a sequence of dynamic degradation issues. Such chaotic systems cannot be considered strictly chaotic, and their applications will be significantly impacted. A control approach is given to handle this problem, which combines parameter perturbation and multi-delay dynamic feedback. This approach utilizes a pseudo-random sequence produced by a high-performance chaotic system to disturb the parameters, then loops back the output of the previous state to the input based on its activity. Numerical studies were conducted to verify the usefulness of this enhanced technique when used in both one-dimensional and two-dimensional chaotic systems. Using a two-dimensional chaotic system as an example, it was confirmed that the enhanced digital chaotic system is extremely responsive to little variations in the starting value. Subsequently, a key generator was created, which successfully passed the NIST randomness test. The experimental results demonstrate that the enhanced digital chaotic system has favorable chaotic properties within the constraints of low precision.

Published: November 2024

Abstract
Perovskites, both natural and synthetic, form a large class of materials are a vast class of materials with significant technological relevance due to their remarkable physical properties, such as superconductivity, magnetoresistance, ionic conductivity, and diverse dielectric behaviors. In this study, the dielectric relaxation and transport properties of the double perovskite Dy2CoMnO6(DCMO) synthesized via high-energy ball milling are investigated. DCMO exhibits a notably large dielectric constant, attributed to a combination of intrinsic and extrinsic mechanisms. Frequency-dependent dielectric studies reveal non-Debye-like behavior, validated by augmented Havriliak-Negami function fitting. Impedance spectroscopy confirms the semiconducting nature of DCMO, showing a negative temperature coefficient of resistance, and identifies two distinct relaxation processes corresponding to grain boundaries and grain interiors thereby highlighting the impact of microstructure and defects. The Cole-Cole plot further supports the non-Debye behavior, while thermally activated relaxation suggests damped charge carrier dynamics at grain boundaries. Conduction analysis using augmented Jonscher's power law reveals non-overlapping small polaron tunneling as the dominant mechanism driving both the dielectric response and transport properties, with DC conductivity suggesting a three-dimensional variable range hopping model. These results provide significant insights into the dielectric and transport properties of DCMO, highlighting its promising potential for advanced electronic applications.

Abstract
In this study, a novel approach has been utilized to Please specify the corresponding author.explore the room temperature thermoelectric properties of zigzag phosphorene nanoribbon-based monolayer-bilayer-monolayer junctions. To achieve thermoelectric properties at room temperature, a quasi-flat energy band with limited width is required. It has been demonstrated, for the first time, that such bands can be observed by considering a junction of the monolayer and bilayer phosphorene nanoribbons. By adjusting the ribbon widths, quasi-flat bands are produced. This geometrical problem is solved using analytical calculations for a general system and applied to phosphorene. We show that the edge states of phosphorene resemble a one-dimensional tight-binding system, with a close agreement between their results. Using the introduced approach, we calculate the electronic energy band structure of the specified system. Initially, we demonstrate that the formation of zigzag monolayer-bilayer-monolayer junctions can lead to the emergence of quasi-flat impurity bands within the energy bandgap. Furthermore, we show that utilizing these structures at room temperature, across a wide range of lead temperature differences, results in significant output electrical power and improved thermoelectric efficiency. The electrical power and thermoelectric efficiency are examined as functions of applied bias voltage and average chemical potential. Additionally, we explore how the output electrical power, thermoelectric efficiency, and efficiency at maximum power vary with the temperature difference between the leads at the ends of the structure.
Constructing viable interacting dark matter and dark energy models: a dynamical systems approach
Authors: Ashmita  , Banerjee Kinjal , Das Prasanta Kumar 
Published: November 2024

Abstract
We study the evolution of k = -1 FLRW cosmological models for two interacting Dark Matter-Dark Energy Models using dynamical system analysis. Since we are interested in late time evolution, the sign of the interaction term is chosen such that it facilitates the transfer of energy from dark matter to dark energy. We also explore the k = 0 invariant subspace of these models. We find that both these models have sectors which have a stable fixed point where we can recover an accelerating universe with a negative equation of state. This indicates these can be viable models for our universe. We also rule out certain sectors of these models because they do not give the correct late time observational features. We observe that although we start with a dust-like Dark Matter, its effective equation of state evolves due to its interaction with Dark Energy. As a result, the Dark Matter can display features of stiff matter and exotic matter in the course of evolution.

in the absence of external fields in a diamond sample. ZFS is a key parameter for using NV centres as quantum sensors for probes of magnetic and electric fields, temperatures and strains. The ZFS is generally detected using coherent spin manipulation by sweeping microwaves (MWs) at frequencies close to resonance with the ZFS. In this article, we report our experimental observations of the red-shift effect on the ZFS as a function of the MW power for two different thermal environments of the sample. We find asymptotic properties of the red shifts of the ZFS. Given the identical initial thermal equilibrium states of the sample, the differences in the raw values of the ZFS between the two cases randomly vary from 47 kHz to 1505 kHz over the entire experimental range. According to the asymptotic approximation, the difference is reduced to 29 kHz–166 kHz with a standard deviation of 49 kHz, suggesting a significant elimination of the red-shift effect. To the best of our knowledge, no other study has addressed the quantification and elimination of the red shift-effect of the MW field dependence using the asymptotic approximation.
