Constraining vector dark matter and dark photon with degenerate mass in a hidden local SU(2) model
Authors: Nomura Takaaki , Xu Xinran 
Published: February 2025

Abstract
We discuss almost degenerate vector dark matter and dark photon that are induced from hidden SU(2)H gauge sector where it is spontaneously broken by vacuum expectation value of SU(2)H doublet. Kinetic mixing between SU(2)H and U(1)Y gauge fields can be generated by introducing dimension six operator realizing dark photon interactions. In estimating relic density we focus on the process in which dark matter annihilate into dark photons, and search for the region of dark matter mass and gauge coupling realizing observed relic density. We then discuss constraints from dark photon physics, thermalization of dark sector and direct detection of dark matter. It is then&#xD;found that constraints from direct detection experiments give us the strongest upper limits on the dark photon interactions.

Published: February 2025

Abstract
In this work, we explore the effect of deformation of the nuclei on collective flow in relativistic heavy-ion collisions.&#xD;The parameter associated with the geometrical deformation in the Glauber model is tuned to reproduce the empirical multiplicity probability distributions correctly.&#xD;Subsequently, the particle spectra and collective flows for Au+Au and U+U collisions are evaluated using a hybrid hydrodynamic code CHESS.&#xD;We analyze the effects of the degrees of freedom associated with the IC on the final-state flow harmonics by exploring the parameter space of the former.&#xD;The connection between the deformation parameters, specifically $\beta_2$ and $\beta_4$, and the flow anisotropies is scrutinized.&#xD;In particular, deviations in elliptic flow at $p_{\mathrm{T}}\sim 2$ GeV are observed at smaller values of $\beta_2$ in Au+Au collisions.&#xD;On the other hand, for U+U collisions, the averaged overall flow harmonics are found to be less sensitive to the geometrical parameters.&#xD;Despite the difference in the model's specifications, our findings largely confirm those obtained in the literature employing different approaches, which indicate that flow harmonics can be used as a sensible probe for the initial geometry fluctuations and to discriminate between different theoretical models.
Carbon tracing method for regional distribution network with load-side electric energy substitution
Authors: Liu Han , Yue Fuchang , He Jie , Su Xiaodong , Li Guangxi 
Published: February 2025

Abstract
One of the primary forms of energy transformation, known as electricity substitution, plays a crucial role in achieving the “dual carbon” goals by replacing the combustion of traditional fossil fuels with electricity. However, this substitution also leads to carbon emissions within the power system. To address this issue, a regional carbon tracing method for load-side electricity substitution in distribution networks is proposed to analyze the decarbonization benefits of pre and post-electricity substitution. Initially, a precise carbon emission tracing model is developed based on the iterative nature of carbon emission flows. Subsequently, adjustments are made to carbon emission intensity to rectify the unfair allocation of carbon emissions from electricity substitution loads to different nodes, thereby establishing a load-side electricity substitution model. The effectiveness of this method is demonstrated through an example involving a distribution network in the East China region. The results highlight that this approach offers a more equitable assessment of carbon emissions from electricity substitution loads and provides scientifically accurate quantitative data for evaluating decarbonization metrics and the efficiency of energy-saving technologies in regional distribution networks.

Abstract
TPMS is a kind of special surface structure constructed by the implicit equation. It has good development potential in the heat transfer area and is regarded as one of the advanced heat exchangers with compact and high efficiency. Based on the existing theories, The convective thermal performance of three TPMS is studied in this paper, Lidinoid, Neovius and Splitp. The results show that when the porosity is 50%, the Splitp structure exhibits the best comprehensive overall performance, while the Neovius show the worst comprehensive thermal capacity and has the highest convective thermal coefficient but larger pressure. There are many through-hole structures in Splitp structure. If the porosity increases, it may affect the heat transfer process, which needs further study in the future.

Published: February 2025

Abstract
Due to the excellent output power and thermal efficiency, the marine diesel engine is the main source of power generation and propulsion for most marine ships at present. For diesel engines, the fuel injection system is the core of various advanced combustion control technologies. However, when the injector nozzle erosion occurs, the flow inside the nozzle and the injection characteristics of the injector will be influenced, which will affect the atomization of the spray and the subsequent combustion and engine performance. Therefore, in this paper, the influence of erosion on the flow inside the nozzle, and the spray atomization characteristics are studied by simulation. The results showed that erosion directly affects the flow rate inside the nozzle, which may be positive or negative. The erosion could generate stronger geometrically induced cavitation, which could lead to the further development of cavitation erosion. Besides, erosion can promote spray atomization to some extent.

Abstract
Based on the self-shrinkage effect of liquid metal and its high electrical and thermal conductivity, liquid metal energy dissipator has a good application in the energy absorption branch of high-voltage DC system. However, the liquid metal energy dissipator is a closed device, and liquid metal vapor will be generated during its working process, which increases the pressure in the cavity, so the change characteristics of pressure in the cavity and its influencing factors also affect its energy consumption capacity and its service life. In this paper, the force and motion of liquid metal are analyzed, a mathematical model of shrinkage time before arc is constructed, the influence of short-circuit current and pore size on shrinkage time is explored, and the key factors affecting shrinkage time are clarified. Based on the theory of magnetohydrodynamics, the whole process of liquid metal from the beginning of contraction to the truncation of arc is simulated, so as to obtain the change characteristics of physical parameters such as pressure and Lorentz force in the cavity during the shrinkage process, and study the influence on the contraction time by adjusting the short-circuit current and aperture size. A GaInSn liquid metal energy dissipation test platform was built, and the pre-arc shrinkage characteristics of GaInSn liquid metal were studied, the variation of voltammetry characteristic curve during liquid metal energy dissipation was detected, and the accuracy of the simulation model was verified by experimental data. This study provides a theoretical reference for liquid metal energy dissipators applied to different grades of power systems.

Published: February 2025

Abstract
Conductive metal-organic frameworks (MOFs) have potential applications as critical functional materials in electronic devices such as chemiresistive sensors, capacitors and batteries. However, the widespread adoption of MOFs in devices is limited by the lack of reliable methods to generate uniform distributions of the MOFs in situ that are strongly adhered to the desired substrates. Here we present a method of synthesising electrically conductive Cu3(HITP)2 and Ni3(HITP)2 MOFs from Cu and Ni metal nanoparticles. The metal nanoparticles are deposited from a magnetron plasma sputtering source onto substrates that include cotton, glass, gold and paper. These nanoparticle-decorated substrates are then immersed in a mildly alkaline solution of the ligand in the presence of an electrolyte. This results in the growth of MOF on the substrate only where the metal nanoparticles were deposited. The described method overcomes problems associated with drop-casting suspensions of the conductive MOF by generating uniform distributions in situ on the substrates. Both MOFs were generated successfully on all four of the substrates, with no preference for conducting or insulating substrates. The mild chemical synthesis environment and proven success with a variety of substrates indicate that the method is likely to be of wide applicability.

Authors: Su Ge , Tian Ye 
Published: February 2025

Abstract
Iris recognition is a very popular and efficient biometric method that has a wide range of applications in finance, security and many other areas. The uniqueness and invariance of the iris makes it highly accurate in identification. Although there are many approaches to iris recognition, such as deep learning based methods, drawbacks such as high computational complexity, high memory requirements, and long training times still exist. Since BP neural networks have the advantages of simple structure and short training time, this paper, an iris recognition method based on improved sparrow search algorithm (CRSSA) optimized back propagation neural network (BPNN) is proposed. The sparrow search algorithm is improved using improved Kent chaos mapping strategy, Dynamic adaptive weight strategy and Logarithmic spiral-based random walk strategy. Then the improved algorithm is used to optimize the BP neural network. Finally, the improved network is used as a classifier for iris recognition. Preprocessing of iris images using Hough transform based processing. The iris image is processed using feature extraction methods based on first order statistical measures and second order statistical measures (F-S) and finally iris recognition is performed using the method proposed in this paper. The experimental results show that the method proposed in this paper exhibits higher recognition accuracy and stability than other algorithms in the experiment on CSAIA-iris-V4 and JLU-4.0 datasets. The improved sparrow search algorithm (CRSSA) proposed in this paper also performs better than the other algorithms in the experiments in terms of convergence accuracy and stability.
Forgery in Musical Composition
Authors: Reece Frederick 
Published: February 2025

Abstract
Forgery in Musical Composition charts the history of forgery in classical music culture from the 1790s to the 1990s. Addressing the topic in depth for the first time, it exposes how and why musical counterfeits are made, casting new light on canonical composers such as Haydn, Mozart, and Schubert alongside prominent musicians like Fritz Kreisler and Glenn Gould. Drawing on a wealth of scores, primary sources, and interviews, the study explains how skillful fakers have succeeded in the past while also proposing active steps that scholars and musicians can take to better identify deceptive compositions in the future. Counterintuitively, the record shows that fake historical masterpieces have often seduced listeners not simply by imitating old works, but rather by mirroring modern cultural beliefs about innovation, identity, and meaning in music. With all this in mind, the book ultimately proposes that forged compositions have important truths to tell us about knowing and valuing works of art precisely because they are not what they appear.
Introduction
Authors: I. Córdova Hidalgo Amalia 
Published: February 2025

Abstract
This study aims to counter the perception of Indigenous cinemas in Latin America as an isolated and marginal practice, positioning its production as a rich and diverse field of inquiry, a sophisticated expression of diverse Indigenous knowledges and lifeways and a locally grounded yet transnational movement that reaches beyond calls for decolonization, becoming a particularly fertile site for the exercise of Indigenous self-determination. The chapter establishes the general corpus and methodology of the study, which traces the emergence of Indigenous filmmaking in Latin America as a nonlinear, imperfect genealogy of junctures, processes, and mediations that forms long-lasting organizations, bonds, and networks. The chapter also offers a brief overview of the ensuing chapters.

Published: February 2025

Abstract
This chapter presents the major festivals and circulation initiatives that promote and exhibit Indigenous media production, tracing their emergence, breaks, and continuities. It describes how Indigenous film festivals constitute spaces of mediation between diverse cultural, social, and political forces; participate in the strengthening of the dynamic networks that support Indigenous media training, production, and exhibition; and, ultimately, open spaces for Indigenous expression and self-representation, despite regional differences, language barriers, and lack of policy. It discusses the multiple roles of Indigenous film festivals in the struggle for Indigenous cultural resistance, focusing on their effect on the trajectories of Indigenous media-makers and in the development of a global Indigenous film circuit.
Strategies in GATT and WTO Negotiations
Authors: Das Abhijit 
Published: February 2025

Abstract
While many books have examined strategies in commercial negotiations among private entities, there has hardly been any attempt at systematically analysing negotiating strategies in multilateral trade negotiations involving governments at the erstwhile General Agreement on Tariffs and Trade (GATT) and subsequently the World Trade Organization (WTO). Based on unparalleled access to first-hand accounts of key negotiators from India and other developing countries, Strategies in GATT and WTO Negotiations provides a systematic identification and comprehensive analysis of strategies and tactics deployed by the main players at the GATT/WTO negotiating table, particularly from the perspective of developing countries. This technically rich and lucidly written book will help readers comprehend the role strategy plays in the developed countries prevailing in WTO negotiations on most occasions. The reader will also understand the dynamics and strategies behind the rare successes of many developing countries in countering entrenched power equations at the GATT and WTO negotiating table. It includes a fascinating analysis of action behind the scenes and strategies deployed by many developing countries in securing some of their key negotiating objectives on three specific issues in the Doha Round of the WTO—Singapore Issues, Agriculture negotiations, and Food Security. The ‘insider’ accounts of some of the key negotiators add value to the known knowledge about how the strategies and tactics are practiced, which is often lacking in most theoretical accounts from academics who stand at an arms-length from these negotiations. The book provides a template for spawning a new stream of academic research on negotiating strategies in international organizations.

Abstract
Sea star wasting syndrome (SSWS) has affected numerous species of sea star, with populations of Pycnopodia helianthoides (Brandt, 1835) left most at risk. As their populations are struggling to recover, it is important to gain a better understanding of the impacts that the multiple stressors in their habitats can have on their populations. Contaminant stressors in particular are of increasing importance, as aquatic organisms can be exposed to a dynamic range of contaminants from nearby anthropogenic activity that may affect their future recovery efforts. This study is the first to quantify the effects of contaminant stressors on the larvae of P. helianthoides. We exposed P. helianthoides larvae to the neonicotinoid insecticide imidacloprid and polyester microfibers, both individually and in combination, at environmentally relevant concentrations (10 ng/L and 25 fibers/L, respectively) to measure the effects of these contaminants on their early life stages. Imidacloprid exposure resulted in stomach malformation in 10% of larvae and increased mortality during early development (p &lt; 0.001), and all treatments resulted in increased larval lengths relative to controls (p &lt; 0.001). During settlement, imidacloprid resulted in more rapid settlement responses than in the controls (p &lt; 0.01). These findings highlight the need for further research investigating the effects of contaminant stressors to endangered organisms during reintroduction, as well as a more comprehensive understanding of the effects of pesticides to non-target organisms.
Reduced Efficacy of Selection on a Young Z Chromosome Region of Schistosoma japonicum
Authors: Mrnjavac Andrea , Vicoso Beatriz 
Published: February 2025

Abstract
Sex-linked and autosomal loci experience different selective pressures and evolutionary dynamics. X (or Z) chromosomes are often hemizygous in males (or females), as Y (or W) chromosomes often degenerate. Such hemizygous regions can be under greater efficacy of selection, as recessive mutations are immediately exposed to selection in the heterogametic sex leading to faster adaptation and faster divergence on the X chromosome (the so-called Faster-X or Faster-Z effect). However, in young nonrecombining regions, Y/W chromosomes often have many functional genes, and many X/Z-linked loci are therefore diploid. The sheltering of recessive mutations on the X/Z by the Y/W homolog is expected to drive slower adaptation for diploid X/Z loci, i.e. a reduction in the efficacy of selection. While the Faster-X effect has been studied extensively, much less is known empirically about the evolutionary dynamics of diploid X or Z chromosomes. Here, we took advantage of published population genomic data in the female-heterogametic human parasite Schistosoma japonicum to characterize the gene content and diversity levels of the diploid and hemizygous regions of the Z chromosome. We used different metrics of selective pressures acting on genes to test for differences in the efficacy of selection in hemizygous and diploid Z regions, relative to autosomes. We found consistent patterns suggesting reduced Ne, and reduced efficacy of purifying selection, on both hemizygous and diploid Z regions. Moreover, relaxed selection was particularly pronounced for female-biased genes on the diploid Z, as predicted by recent theoretical work.

Abstract
Acute liver failure (ALF) is a serious disease that progresses from acute liver injury (ALI) and that often leads to multiorgan failure and ultimately death. Currently, effective treatment strategies for ALF, aside from transplantation, remain elusive, partly because ALI is highly heterogeneous. Furthermore, clinicians lack a quantitative indicator that they can use to predict which patients hospitalized with ALI will progress to ALF and the need for liver transplantation. In our study, we retrospectively analyzed data from 319 patients admitted to the hospital with ALI. By applying a machine-learning approach and by using the SHapley Additive exPlanations (SHAP) algorithm to analyze time-course blood test data, we identified prothrombin time activity percentage (PT%) as a biomarker reflecting individual ALI status. Unlike previous studies predicting the need for liver transplantation in patients with ALF, our study focused on PT% dynamics. Use of this variable allowed us to stratify the patients with highly heterogeneous ALI into six groups with distinct clinical courses and prognoses, i.e. self-limited, intensive care–responsive, or intensive care–refractory patterns. Notably, these groups were well predicted by clinical data collected at the time of admission. Additionally, utilizing mathematical modeling and machine learning, we assessed the predictability of individual PT% dynamics during the early phase of ALI. Our findings may allow for optimizing medical resource allocation and early introduction of tailored individualized treatment, which may result in improving ALF prognosis.

Published: February 2025

Abstract:
Peripheral nerve sheath tumors can include neurofibroma, schwannoma, and perineurioma, with hybrid nerve sheath tumor (HNST) being rare. We describe 3 HNST cases with epithelioid schwannoma and neurofibroma features, an uncommon manifestation of hybrid schwannoma/neurofibroma. The 3 cases involved the upper back, forearm, and thigh. Histopathologically, the tumors were located in the subcutis or dermis and subcutis. The epithelioid schwannoma component showed nests/cords of epithelioid cells with round nuclei and abundant cytoplasm. In contrast, the neurofibroma component showed spindle cell proliferation within myxoid stroma. The 3 cases showed variable proportions of both components. Immunohistochemically, the epithelioid schwannoma components were positive for S100 protein and negative for CD34, whereas the neurofibroma component showed partial S100 immunoreactivity and contained abundant CD34-positive cells with a fingerprint pattern. Epithelial membrane antigen and GLUT1 revealed the perineurial capsules. In conclusion, our cases expand the morphologic spectrum of HNST and underscore the importance of recognizing this variant.
