How the hadron gas affects X(3872) and ψ(2S) production in heavy ion collisions
Authors: Abreu Luciano M. , Navarra Fernando S. , Vieira Hildeson P.L.
Published: December 2024

The X(3872) to ψ(2S) yield ratio (NX/Nψ(2S)) has been recently measured in pp, pPb and PbPb collisions by the LHCb and CMS Collaborations at the LHC. It was found that this ratio grows with the system size and this growth was attributed to the formation of quark gluon plasma and/or of a hot hadron gas. Here we focus on the effects of the hadron gas on the abundance of X(3872) and ψ(2S). The interaction of charmonium states with the light mesons in the gas can be studied with an effective Lagrangian formalism. One can calculate the relevant cross sections and use them as input in rate equations. With this formalism one can follow the time evolution of the X(3872) and ψ(2S) abundances until the final freeze-out of the gas. The initial conditions for this evolution are given by the coalescence model, which depends on the spatial configuration of the states and yields quite different numbers for compact tetraquarks and extended meson molecules. It has been found that the interactions in the hadron gas yield a suppression in most of the states and, most importantly, preserve the difference between the number of tetraquarks and the number of meson molecules, formed at the beginning of the hadronization. We discuss the predictions made for the ratio NX/Nψ(2S) in PbPb collisions at √sNN = 5.02 TeV to be measured by the ALICE Collaboration in the Run 3. The existing calculations suggest that the molecular configuration generates a ratio compatible with the CMS data, whereas the ratio obtained with the tetraquark configuration is 50 times smaller.

Authors: WANG Qiang , ZHU Chenming , PAN Su , QIN Yuxi
Published: December 2024

To address the problem that there is no standard for the parameter selection of support vector machine (SVM) algorithm, a parameter optimization selection method based on the integrated improved differential evolution (IDE) algorithm is proposed, which uses the minimization of the classification error rate as the optimization criterion and the improved differential evolution algorithm to optimize the combination of SVM parameters to obtain an SVM algorithm with higher classification accuracy. At the same time, to avoid the basic DE algorithm from falling into local optimum when solving the SVM parameter selection problem and to improve the search efficiency of the DE algorithm. In this paper, an improved differential evolutionary algorithm is proposed to obtain a DE algorithm with faster convergence and higher accuracy by using the circular arc function for adaptive control of the variance scaling factor F and the crossover probability factor R, combining with the random newborn individual replacement operation. Based on this, an IDE-SVM IoT physical layer security method based on IDE-SVM is proposed. The experimental results show that the authentication accuracy of the physical layer security method based on the improved SVM algorithm is higher than others.

Authors: DUO Lin , YANG Xin , REN Yong , XU Boyu
Published: December 2024

Aiming at the scarcity of communication spectrum resources and the advantages of cell-free MIMO in resource utilization, a millimeter-wave cell-free MIMO-ISAC system is proposed. In this system, while the base station provides services for users, the multi-antenna user equipment can actively detect multiple targets. The research goal is to design analog and digital beamformers to optimize the weighted sum of communication and radar beamforming errors. Two kinds of power constraints are considered in the study, and the improved orthogonal matching pursuit algorithm and the Riemann conjugate gradient algorithm are used for optimization. Through the simulation analysis of the communication spectrum efficiency and the radar beam pattern, the results show that the hybrid beam scheme can achieve a compromise performance in terms of spectrum utilization and beam pointing, and this scheme has potential application prospects for improving system performance.

Authors: Phan Franck , Bertrand Romane , Amouyal Chloé , Andreelli Fabrizio
Published: December 2024

L’idée de traiter les diabètes sucrés par des hormones intestinales a été proposée dès les débuts de l’endocrinologie, en 1902, mais ne sera mise en pratique qu’au début des années 2000. La mise en évidence d’une majoration de la sécrétion d’insuline après l’administration de glucose par voie orale par rapport à son administration intraveineuse, connue sous le nom « d’effet incrétine », a été suivie de la découverte des deux principales hormones intestinales responsables de cet effet : le GIP (glucose-dependent insulinotropic polypeptide) et le GLP-1 (glucagon-like peptide-1). La réduction de l’effet incrétine contribue à la pathogenèse du diabète de type 2, ce qui a conduit à développer des thérapies innovantes successives, comme les analogues du GLP-1, les agonistes du récepteur du GLP-1, les co-agonistes GIP / GLP-1 et les triagonistes GIP / GLP-1 / glucagon. Ces médicaments aux effets hypoglycémiants et pondéraux puissants ont modifié radicalement notre prise en charge thérapeutique du diabète de type 2 et de l’obésité.

Authors: Chen Ziran , Liu Yaohua , Ren Shuyan , Zeng Yutong
Published: December 2024

Social media has become a key platform for public discussion and dissemination of social events but has also led to the Echo chamber effect and emotional polarization. This study uses the “Jiang Ping incident” as a case to explore emotional polarization in public opinion on Chinese social media platforms, specifically Weibo. The study first reviews relevant theories, including the Echo chamber effect, selective information preference, silence behavior, and opinion-emotional contagion. Then, using a questionnaire survey, empirical data were collected, and factor analysis was conducted to extract key common factors influencing emotional polarization. In the final regression analysis, the impact of these three common factors on the polarization of public opinion groups was further examined. The results show that selective information preference and opinion-emotional contagion have a significant negative impact on emotional polarization. Additionally, silence behavior was also found to have a negative impact on emotional polarization, suggesting that users’ silence behavior in the face of opposing opinions may exacerbate the degree of emotional polarization. Finally, the study provides recommendations for social media platform managers and policymakers to mitigate emotional confrontation on social media and promote more rational public discussion.
An Exploration of Chinese Netizens’ Perception of Symbolic Violence in Medical Cosmetology in the Chinese Video Media Bilibili
Authors: Wang Yang
Published: December 2024

China’s medical cosmetology industry has developed rapidly in recent years, and the Internet, especially social media platforms such as Bilibili, has become an important channel for the public to obtain information. However, the objectivity and fairness of medical cosmetology video content on the platform are questionable, affecting public perception. This paper delves into the phenomenon of symbolic violence within Bilibili’s medical cosmetology video content, examining how certain narratives and representations can subtly reinforce societal norms and biases, ultimately impacting viewers’ attitudes and beliefs. Through a combination of data mining and content analysis techniques, we uncover the characteristics of video dissemination on the platform, including the prevalence of specific uploaders who dominate the discourse with their views and experiences. This unequal distribution of discourse power can lead to a skewed representation of the medical cosmetology field, with some voices being amplified while others are marginalized. The public is concerned about the risks of medical cosmetics, but successful cases are also recognized. The study emphasizes the importance of enhancing public rationality, promoting healthy media communication, and promoting the healthy development of the industry.

Published: December 2024

It is demonstrated that in a magnetic field parallel to the surface of a thin metal film Umklapp processes occuring during specular reflection of charge carriers on the specimen boundary lead to a generation of an rf field spike in the depths of the metal, the intensity of which is of the same order of magnitude as that of the electromagnetic field in the skin layer. An additional series of rf size effect lines permits observation of Umklapp processes and determination of their probability.
Orthophonon excitations in solid hydrogen
Authors: Kokshenev V. B.
Published: December 2024

We have analyzed the dynamical properties of solid hydrogen with a small population of its ortho species. It is shown that the rotational–vibrational interaction of the orthomolecules with the paramolecules may lead to excitation of collective orthophonon vibrations in the crystal. Excitation of the latter is accompanied by rearrangement of the vibrational spectrum of the crystal with formation of a gap of forbidden vibrations. The critical temperature Tc at which the indicated rearrangement takes place is about 0.1 °K for an ortho state concentration c ∼10−2–10−4.
NMR line broadening in isovalent cadmium alloys
Authors: Zhukov V. V.
Published: December 2024

The behavior of the NMR linewidth in disordered Cd–Mg and Cd–Hg alloys in the hexagonal α-phase at host and impurity nuclei have been studied in detail. It is found that spatial inhomogeneity of the Knight shift and its pronounced concentration dependence are the cause of a specific mechanism of resonance line broadening in these isovalent systems. It is shown that the NMR linewidth technque is very informative in the study of the electronic structure of alloys.

Deception is a universal human behavior. Yet longstanding skepticism about the validity of measures used to characterize the biological mechanisms underlying deceptive behavior has relegated such studies to the scientific periphery. Here, we address these fundamental questions by applying machine learning methods and functional magnetic resonance imaging (fMRI) to signaling games capturing motivated deception in human participants. First, we develop an approach to test for the presence of confounding processes and validate past skepticism by showing that much of the predictive power of neural predictors trained on deception data comes from processes other than deception. Specifically, we demonstrate that discriminant validity is compromised by the predictor’s ability to predict behavior in a control task that does not involve deception. Second, we show that the presence of confounding signals need not be fatal and that the validity of the neural predictor can be improved by removing confounding signals while retaining those associated with the task of interest. To this end, we develop a “dual-goal tuning” approach in which, beyond the typical goal of predicting the behavior of interest, the predictor also incorporates a second compulsory goal that enforces chance performance in the control task. Together, these findings provide a firmer scientific foundation for understanding the neural basis of a neglected class of behavior, and they suggest an approach for improving validity of neural predictors.

As the petroleum industry evolves, the challenges associated with petroleum exploration and development intensify, and the continuous measurement of well inclination has grown increasingly significant. Continuous near-bit inclination measurements can improve the accuracy of calculating wellbore trajectory and drilling efficiency. However, the vibration of the bottom drill bit seriously interferes with the inclination measurement, causing serious distortion of acceleration and inaccurate inclination measurement. When the well inclination measurement module is installed eccentrically, it is easy to cause installation errors. At the same time, the drill collar rotates, and the three-axis acceleration is affected by the centrifugal acceleration. The above factors will affect the accuracy of inclination measurement. This paper derives a three-axis acceleration measurement error model caused by installation error, and proposes a continuous measurement method based on this model. First, the vibration noise is filtered out by the Kalman filter. Then a multivariate linear regression model of three-axis acceleration is established, and the true inclination is calculated based on this model. After simulation verification, the continuous inclination error measured by this method is less than 0.2°.

Published: December 2024

In pH control system of acid injection mixture, the flow rate is easily disturbed due to the constant change of displacement in the platform acid flow control loop and the platform water flow control loop. In this study, a control strategy is proposed, that is, both the inner and outer ring controllers are linear active disturbance rejection controllers. The controller adopts linear active disturbance rejection controller, and the pH value of the mixture is controlled by cascade ratio. On the basis of the second order controller, the second order linear active disturbance rejection controller is designed based on the electric throttle valve and mixing tank model, and the simulation platform of pH control system of acid injection mixture is built by MATLAB(MATrix LABoratory)/Simulink. The controller design and simulation results of linear active disturbance rejection control algorithm and PID(Proportional Integral Derivative) algorithm are compared respectively. The simulation results show that under the interference of external uncertainties, the designed controller can not only track pH value quickly, but also reduce the overshoot and the stability time when disturbed, and effectively improve the dynamic response performance and robustness of the system.
