Published: October 2023

One of the fundamental quantities in dynamics of the liquid state, the adiabatic speed of sound $$c_s$$

c
s

, is extremely difficult to predict from computer simulations, especially in ab initio simulations. Here we derive an expression for the instantaneous correlator of fluctuations of longitudinal component of stress tensor, which contains $$c_s$$

c
s

along with others quantities easy accessible via classical and ab initio computer simulations. We show that the proposed methodology works well in the case of Lennard-Jones and soft-sphere simple fluids, Kr–Ar liquid mixture in connection with simulations with effective pair interactions as well as for liquid Sb, fluid Hg and molten NaCl from ab initio simulations.
Study of flexural strength of concrete containing mineral admixtures based on machine learning
Authors: Li Yue , Liu Yunze , Lin Hui , Jin Caiyun
Published: October 2023

In this paper, the prediction of flexural strength was investigated using machine learning methods for concrete containing supplementary cementitious materials such as silica fume. First, based on a database of suitable characteristic parameters, the flexural strength prediction was carried out using linear (LR) model, random forest (RF) model, and extreme gradient boosting (XGB) model. Subsequently, the influence of each input parameter on the flexural strength was analyzed using the SHAP model based on the optimal prediction model. The results showed that LR, RF, and XGB enhanced the accuracy of forecasting sequentially. Among the characteristic parameters, the most significant effect on the flexural strength of concrete is the water-binder ratio, and the water-binder ratio shows a negative correlation with flexural strength. The effect of maintenance age on flexural strength is second only to the water-binder ratio, and it shows a positive trend. When the amount of fly ash is less than 40% and the amount of slag or silica fume is less than 30%, the correlation between the amount of supplementary cementitious materials and flexural strength fluctuates and a positive peak in flexural strength is observed. However, at a dosage greater than the above, the supplementary cementitious materials all reduce flexural strength. The interaction interval and the degree of interaction between the supplementary cementitious materials and the cement content also differ in predicting flexural strength.

Speech Elicitation Methods for Measuring Articulatory Control
Authors: Abbiati Claudia I. , Bauerly Kimberly R. , Velleman Shelley L.
Published: October 2023

Purpose:

Spatiotemporal index (STI) is a common measure of articulatory variability used to examine speech-motor control. However, the methods used to elicit productions for measuring STI have varied across studies. The aim of this study was to determine whether STI values are affected by changes in elicitation methods.

Method:

Lip aperture STI (LA STI) was calculated for 19 monolingual English-speaking young adults based upon the production of four declarative sentences that varied by length and complexity. Using a 2 × 2 design, productions were elicited under the following two conditions: repetition type (consecutive vs. pseudorandom) and stimulus presentation type (auditory vs. combined auditory and visual). Conditions for eliciting productions were counterbalanced among participants.

Results:

There was a main effect of repetition type (
p
< .001) and sentence type (
p
< .030). Pseudorandom repetitions resulted in higher mean LA STI values across sentence types compared to those computed from consecutive repetitions. There were no significant differences for stimulus presentation type. That is, no differences in mean LA STI were found between the auditory versus combined auditory and visual presentations.

Conclusions:

Our findings show that the methods used to elicit sentence productions have a significant effect on LA STI values. Findings suggest that there is a need for researchers to consider these effects when designing methods for measuring LA STI.
The Role of Instructions in Motor Learning of Oral Versus Nasalized Speech Targets
Authors: Perta Karen , Bae Youkyung , Vuolo Janet , Bressmann Tim , Fox Robert
Published: October 2023

Purpose:

The purpose of this study was to investigate how general, implicit instructions with auditory-perceptual emphasis; specific, explicit instructions with biomechanical focus; or both affect learning of oral–nasal balance control in speech.

Method:

Thirty healthy, vocally untrained participants were assigned to one of three instructional groups (i.e., implicit, explicit, and integrated) and learned to produce oral versus nasalized vowel-, syllable-, and phrase-level targets during once-weekly sessions over 4 weeks. Learning gains and performance variability were analyzed using nasometry.

Results:

We observed a significant main effect of instruction type on learning gains at phrase level (
p
= .016). Specifically, the integrated group (
M
= 59.8%) significantly outperformed the explicit group (
M
= 37.9%) and numerically outperformed the implicit group (
M
= 45.1%). For nasalized phrase targets, results revealed a significant main effect of instruction type on performance variability (
p
= .042), but pairwise comparisons between instruction groups were not significant.

Conclusions:

The integration of implicit processes via auditory-perceptual modeling and explicit processes via relevant biomechanical directives resulted in larger motor learning gains, especially at higher levels of task complexity (i.e., phrase) compared to providing implicit or explicit instruction alone. The higher performance variability (i.e., less stable productions) that was sometimes induced by explicit instruction did not negatively impact learning when integrated with implicit instruction. Clinical implications for speech/voice therapy models are discussed.
Long-term PV system modelling and degradation using neural networks
Authors: Guerra Gerardo , Mercade-Ruiz Pau , Anamiati Gaetana , Landberg Lars
Published: October 2023

The power production of photovoltaic plants can be affected throughout its operational lifetime by multiple losses and degradation mechanisms. Although long-term degradation has been widely studied, most methodologies assume a specific degradation behaviour and require detailed metadata. This paper presents a methodology for the calculation of long-term degradation of a photovoltaic plant based on neural networks. The goal of the neural network is to model the photovoltaic plant's power production as a function of environmental conditions and time elapsed since the plant started operating. A big advantage of this method with respect to others is that it is completely data-driven, requires no additional information, and makes no assumptions related to degradation behaviour. Results show that the model can derive a long-term degradation trend without overfitting to shorter-term effects or abrupt changes in year-to-year operation.
Blind PV temperature model calibration
Authors: Kladas Anastasios , Herteleer Bert , Cappelle Jan
Published: October 2023

The determination of module temperature in a photovoltaic (PV) system is a crucial factor in PV modelling and the assessment of system health status. However, the scarcity of on-site temperature measurements poses a challenge, and existing PV temperature models encounter difficulties in accurately estimating temperatures in systems characterized by unique structural or locational attributes. This paper introduces a novel approach that enables the calibration of PV temperature models without relying on direct temperature measurements. Referred to as blind calibration, this method eliminates the requirement for temperature measurements, thus offering a promising solution to the aforementioned challenges. The method is validated using three datasets, demonstrating accurate PV temperature (TPV) estimation with mean absolute errors below 2 °C. The findings highlight the suitability of the proposed approach for various PV system types, while acknowledging limitations regarding certain system configurations.
Yield design-based analysis of reinforced soil structures, making use of different models of reinforced soils
Authors: de Buhan Patrick
Published: October 2023

This contribution is aimed at applying the static and kinematic methods of the yield design theory, initially developed for homogeneous soils, to the stability analysis of reinforced soil structures. Several mechanical models of reinforced soils are considered to this end, starting from the mixed modelling approach which is the most intuitive one, according to which the reinforcements are treated as one-dimensional beam elements embedded in the soil regarded as a three-dimensional continuum. While this first model is posing some difficulties as regards the implementation of the lower bound static approach, a homogenization procedure should be preferred in the case of a dense array of regularly spaced inclusions, leading to the formulation of a macroscopic strength condition for the homogenized reinforced soil. Since the latter formulation, unlike the mixed modelling approach, fails to account for the shear and flexural strength characteristics of the reinforcements, a continuum multiphase description of reinforced soils, which may be considered as an extension of the previous homogenization method, has been developed. Such a multiphase model, which combines the advantages of the two previous models, is able to incorporate in an explicit way not only the shear and bending strength capacities of the reinforcements, but also a specific failure condition at the soil-inclusion interface. This contribution presents some illustrative applications of the yield design theory and related upper and lower bound methods to the design of typical reinforced soil structures, using the three above mentioned models.

Vers une approche pédagogique par compétences en licence Physique Chimie à l’INSA Hauts-de-France-Projet PRéLUDE
Authors: Chehami Lynda
Published: October 2023

L’Université Polytechnique des Hauts de France (UPHF) conjointement avec l’Institut Catholique de Lille (ICL) conduisent depuis 2018 une réexion commune en vue de mettre des parcours de réussite intégrant transdisciplinarité (modules polytechniques et d’ouverture) et approche par compétences (APC). Ceci s’inscrit dans le contexte du Nouveau Cursus Universitaire (NCU) “ePRéLUDE” (Parcours de Réussite en Licence Universitaire à Développement Expérientiel) obtenu par l’UPHF en 2018. Le projet PRéLUDE bénéficie d’une aide de l’état gérée par l’Agence Nationale de la Recherche (ANR) au titre du Programme d’Investissements d’Avenir lancé par l’Etat et mis en œuvre par l’ANR. Ce projet se déploie sur une durée de 10 ans (2018-2028). Dès la rentrée 2022-2023, ils nous a été demandé de commencer le “chantier APC”, i.e ; transformer nos maquettes de cycle licence par une approche par compétences. En licence Physique Chimie dont je suis responsable pédagogique, ce travail a été entamé en Janvier 2023. Ce papier s’inscrit pleinement dans cette nouvelle approche et présente alors une première ébauche sur l’élaboration d’un référentiel de compétences en licence Physique Chimie. L’objectif de ce cursus innovant est de savoir si au terme des trois années de formation, l’étudiant a-t-il appris à “physicier” son environnement ? à “chimiser” son environnement ?
Le Génie de la fiction Plaidoyer pour l’enseignement de l’écriture de la fiction
Authors: Smigiel Eddie , Plantec Jean-Yves
Published: October 2023

Il est d’usage de présenter la science comme étant le domaine exclusif de la réalité, des faits objectifs et démontrés tandis que la fiction serait le territoire de l’imaginaire et de la créativité selon le découpage « cerveau gauche », siège de la rationalité, de l’ordre et la rigueur, de la pensée logique et organisatrice versus « cerveau droit », siège des émotions, de l’affectif et de la démarche artistique. Ce découpage simpliste fortement socio-construit ne tient pas à l’analyse. On montrera dans cet article que l’activité scientifique possède aussi sa part de mise en récit et par voie de conséquence, procède d’un mode fictionnalisant. Inversement, une œuvre de fiction ne consiste pas à écrire tout ce qui passe par la tête de l’auteur à l’imagination débridée. L’œuvre de fiction obéit à une démarche constructive, un génie propre, théorisée et codifiée par le genre auquel elle appartient. Nous montrerons que ce génie de fiction, lorsqu’il est enseigné, peut réconcilier les deux cerveaux. Nous illustrerons le propos par un module électif enseigné à l’INSA Strasbourg, « Filmer la Science » qui présente la théorie de l’analyse filmique ainsi que par l’activité de romancier d’un des auteurs dans laquelle l’imagination doit s’inscrire dans un monde réel aux exigences contraignantes. La pratique de l’écriture de la fiction permet alors de prendre conscience des deux « cerveaux » et de la nécessité pour être productif, de trouver un équilibre entre des forces qui peuvent devenir contraires si elles ne fonctionnent pas harmonieusement.

An exploration of selective justice in the International Criminal Court
Authors: Geng Zhimin
Published: October 2023

With the development of history, human society has experienced the development stage from disorder to law, from domestic law to international law. International law came into being and developed in the context of increasing exchanges between states. International criminal law has emerged and developed in modern times on the basis of the continuous development of international law. The International Criminal Court is also a form of international legal system that has emerged when human society has developed to a certain stage.To punish international criminal criminals more effectively through the trial of the International Criminal Court, to stop, prevent or deter the occurrence of international criminal crimes and potential international criminal criminals is an inevitable historical product of the development of human society to a certain stage, and it is a milestone progress. The International Criminal Court has played a positive role in the protection of human rights in all countries, especially in developing countries. Based on the principle of complementary jurisdiction, the jurisdiction of the International Criminal Court encompasses a set of jurisdictional principles, conditions and procedures to ensure the legality and impartiality of its exercise. These principles, conditions and procedures of jurisdiction have certain particularity. Since the establishment of the International Criminal Court, there has been a problem of selective justice, so this paper tries to discuss the meaning of selective justice in the International Criminal Court, the development of selective justice in the International Criminal Court and the influencing factors of selective justice in the International Criminal Court.

As an important theory of policy process analysis, multiple–streams theory provides a highly explanatory analytical framework and perspective for exploring the dynamics of policy change. This paper uses multiple–streams theory to analyze the history of china’s drug procurement policy changes, found that the china’s drug procurement policy has gone through four development stages. Each change in drug procurement policy is due to a particular problem that is highlighted, focal issues enter the policy agenda when problem streams, policy streams and politics streams are highly coupled and the issue window opens, then the policy changes. This paper provides an outlook on the key directions of china’s drug procurement policy, in order to provide useful reference for the study of multiple–streams theory and the study of china’s drug procurement system.
Regulating Reverse Payment Agreements in Pharmaceutical Market: A Comprehensive Framework for Antitrust Review
Authors: Yang Xupeng
Published: October 2023

Reverse payment settlement agreement is a type of arrangement between original and generic drug manufacturers that could potentially violate Antitrust Laws by limiting competition, typically appear in the pharmaceutical market. This paper addresses the impact of these agreements on public interests, and the challenges in conducting antitrust review on these agreements. This paper then proposes a comprehensive framework for regulating reverse payment agreements in the context of China’s extensive and complex pharmaceutical market by drawing on the experiences of the United States and the European Union. The framework introduces a two-step antitrust review system for regulating patent settlement agreements, which is suggested by the author to be applied in both patent litigation and daily detection. This paper also advocates establishing an agreement filing system and utilizing the antitrust public interest litigation system in antitrust regulation. This proposed framework provides specific guidance on initiation of antitrust review with respect to multiple backgrounds, in order to protect consumer interests in affordable healthcare, deter anti-competitive behavior, and contribute to the theoretical basis for future legislation.

Authors: Ren Chenxue , Tan lingbo
Published: October 2023

Large-scale regional trade agreements have led to a gradual increase in the ease of trade development among countries. The role of geographical distance and other location factors on trade development among countries has gradually diminished, while the institutional conditions of different countries have gradually increased their role on trade development among countries. Given the development process of the RCEP agreement, this study uses panel data from 2011-2021 and explores the mechanism of the institutional quality of RCEP countries affecting China’s import and export trade with them based on a gravity model. In addition, this study explores the level of infrastructure in mediating the effect of the process. It is found that the institutional quality of RCEP countries has a substantial impact on China’s import and export transactions with them. In addition, infrastructure plays a fully mediating effect in the process. Therefore, bilateral trade can be promoted by upgrading the institutional environment, infrastructure development and optimising the business environment.

In the period of rapid development of the knowledge economy, human capital plays a very prominent role in technology-based enterprises. Technological enterprises have characteristics such as high R&D investment, intensive technological talent, and significant impact of human capital on their competitiveness. Employee stock ownership plans can stimulate innovation vitality and improve innovation efficiency. The research on employee stock ownership in technology-based enterprises is still a relatively new field, and there are still some challenges. Employee stock ownership in technology-based enterprises is an incentive mechanism that can effectively improve corporate performance. This article elaborates on the characteristics of employee stock ownership plans, analyzes the process of their impact on corporate performance, and proposes countermeasures and suggestions. Employee shareholding in technology-based enterprises is not a panacea for all problems, and its successful implementation requires specific design and adjustment based on the company’s own situation. In addition, the implementation of employee stock ownership plans may also face some challenges, such as equity allocation, liquidity management, etc., which require rational allocation of resources and handling of interest relationships.
Research on Local Characteristic Industry Construction in Characteristic Towns under Public-Private Partnership Development Mode
Authors: Jyh-Hang Shyng
Published: October 2023

In recent years, there’s been a global trend of emphasizing the role of local characteristics in steering economic growth. To foster the advancement of local characteristic industries in characteristic towns, the public-private partnership (PPP) model is being adopted. This strategy leverages social resources and governmental incentives to drive both urban and rural progress, thus becoming a silver bullet to bolster the growth of characteristic towns. However, achieving “town-industry integration” and “sustainable development” necessitates shared consensus and understanding among all stakeholders. Given the intricate nature of the PPP mechanism, a comprehensive theoretical framework tailored to Chinese local characteristics is essential. This study scrutinizes the integration of the PPP model into characteristic industries within small Chinese towns. It follows a framework encompassing theoretical characteristics, feasibility analysis, existing problems, countermeasures, and recommendations, as well as future trends. The study employs both inductive reasoning and comparison. The research findings serve to establish a theoretical consensus for the PPP model’s integration with characteristic industries in these towns, benefiting all involved parties.
