A Novel Dual‐Loop Model‐Free Adaptive Iterative Learning Control and Its Application to the Refrigeration Systems
Authors: Ibrahim Nasreldin , Dong Na 
Published: December 2024

ABSTRACTThis study investigates a novel dual‐input and dual‐output Model‐Free Adaptive Iterative Learning Control (A‐MFAILC) approach for energy‐saving control of refrigeration systems, aiming to maintain a minimum stable superheat and a constant evaporation temperature. Superheat control is often unstable due to the complex and high‐order nature of refrigeration systems. Furthermore, these systems often face large time delays, which complicate the tracking control process. Such delays can cause inefficiencies and instability in maintaining desired operational parameters, making it challenging to achieve energy savings. To get around these problems, a novel Model‐Free Adaptive Iterative Learning Control algorithm has been proposed by incorporating input rate constraints for time‐delayed systems.The proposed A‐MFAILC algorithm with a single input and single output has been extended to dual input and dual output energy‐saving control of refrigeration systems. Complete proofs of convergence analysis have been provided, and the algorithm's performance has been fully evaluated. Simulation tests based on the proposed A‐MFAILC algorithm, developed for dual‐loop control systems, have been conducted on refrigeration systems. Step signals have been used as input signals for comprehensive performance testing. As a result, the proposed approach demonstrates higher tracking stability and fast response speed, with an average tracking accuracy of 98.68% and 93.87% for superheat and evaporation temperature, respectively.
Decentralized Periodic Event‐Triggered Control for Nonlinear Switched Systems

Published: December 2024

ABSTRACTDecentralized periodic event‐triggered control (DPETC) is a method that allows sensors to be placed flexibly while cutting down on their workload and the amount of data they send in a feedback loop, which makes it a good fit for wireless network control systems. In this article, we investigate the control issues of nonlinear switched systems whose switches are determined by the system input and consider their stability by designing a DPETC scheme. Additionally, we model and control a water distribution system with looped pipe network using a switched model and the proposed theory. In this DPETC, at each periodic sampling time, the local event‐triggered mechanism determines events by assessing whether the local sampling error meets the predefined triggering condition. If so, the collected sampling data will be transmitted to a central controller. This controller processes the data to compute the control input, with those nodes without events using the previous updated sampling data. Based on the derived control input, the controller then switches to the appropriate mode following the system's switches. The feasibility of the proposed method is demonstrated through three examples, including a smart water distribution system with looped pipeline.

Published: December 2024

ABSTRACTIn recent years, the circular economy (CE) has emerged as a critical strategy for sustainable development, addressing environmental challenges, resource efficiency, and waste reduction. Although the advantages of CE over traditional linear economic models are well‐documented, less attention has been given to understanding how CE is perceived and discussed in public forums such as social media. This paper aims to fill that gap by analyzing Twitter conversations related to CE from 2012 to 2022, using advanced Natural Language Processing (NLP) techniques. A total of 389,575 tweets were collected and processed to uncover the main themes, trends, and influential entities in the global CE discourse. The analysis shows that waste management, recycling, and resource efficiency are the most prevalent topics, reflecting the public's concern for practical CE applications. Additionally, technological advancements such as blockchain and IoT are emerging as significant drivers of CE innovation. Countries like the United Kingdom, China, and India, along with key organizations like the European Commission and the Ellen MacArthur Foundation, are central to the global CE narrative. These findings provide critical insights for policymakers, corporations, and researchers, highlighting areas of public interest and potential collaboration to advance CE initiatives. By aligning strategies with social media discourse, stakeholders can promote more effective, widespread adoption of CE principles.
ESG Information Disclosure and Its Relationship to Tax Practices: Stakeholder‐Friendly or Legitimacy‐Seeking?

Published: December 2024

ABSTRACTTax laws may promote practices that lead to tax deductions or deferrals over time and that relate to corporate environmental, social, and governance (ESG) disclosures. This study analyses whether transactions that have corporate tax effects are related to tax avoidance or are a way of channeling ESG commitments. In addition, we investigate whether the firm financial situation moderates the incidence of ESG disclosure on tax practices. The results show that ESG disclosure have a positive impact on permanent tax differences, which are produced by philanthropic, among others. However, the effect of ESG disclosure on temporary differences, which can be related to tax avoidance practices, is negative. Companies committed to ESG do not engage in tax avoidance. Regarding the moderating effect of financial indicators, the results show that only profitability positively moderates the relationship between ESG disclosure and temporary tax differences. ESG disclosure could be used to hide tax avoidance practices. The findings have important implications for policymakers, supporting the creation of effective regulations that incorporate companies' tax practices into the ESG objectives. This will encourage companies to be more conscientious about their tax behaviors.

Published: December 2024

AbstractThe crystal phase of pseudocapacitive materials significantly influences charge storage kinetics and capacitance; yet, the underlying mechanisms remain poorly understood. This study focuses on tungsten oxide (WO3), a material exhibiting multiple crystal phases with potential for energy storage. Despite extensive research on WO3, the impact of different crystal structures on charge storage properties remains largely unexplored. Here, the successful synthesis and electrochemical characterization of tetragonal WO3 are reported. This investigation demonstrates that tetragonal WO3 exhibits superior energy storage capabilities compared to other WO3 polymorphs. According to in situ Raman spectroscopy and ultraviolet photoelectron spectroscopy combined with in‐depth electrochemical analyses, this enhancement is attributed to a unique charge storage mechanism and an expanded potential window facilitated by an engineered electrode work function. This study highlights the critical role of the crystal phase in optimizing the performance of pseudocapacitive materials and provides valuable insights for the development of next‐generation energy storage devices.
Measuring Alcohol‐Induced Striatal Dopamine Release in Healthy Humans With [11C]‐Raclopride: A Meta‐Analysis
Authors: Kania Amir , Porco Natasha , Caravaggio Fernando 
Published: December 2024

ABSTRACTAlcohol consumption is known to affect dopamine (DA) release in the brain, with significant implications for understanding addiction and its neurobiological underpinnings. This meta‐analysis examined the effects of acute alcohol administration on striatal DA release in healthy humans as measured with [11C]‐raclopride positron emission tomography (PET). Oral alcohol administration was associated with a significant reduction in [11C]‐raclopride binding potential (BPND) in the ventral striatum (Cohen's d = –0.76), indicative of increased DA release, particularly at lower blood alcohol concentration (BAC) levels (0.08 gm%; Z = 2.34, p = 0.02). That oral alcohol may increase DA release in the ventral striatum at lower doses, and decrease DA release at higher doses, warrants further investigation but appears consistent with other known biphasic, hermetic dose–response effects of alcohol. Additionally, larger effect‐sizes in the ventral striatum were observed among those studies which sampled more males than females (Z = –2.08, p = 0.04). While oral alcohol administration was associated with reduced [11C]‐raclopride BPND in the caudate (Cohen's d = –0.39) and putamen (Cohen's d = –0.37), these findings in the dorsal striatum were more variable and less robust. Our analyses suggests that study design (i.e., counterbalanced versus fixed order) may moderate effect sizes observed in the putamen across studies (Z = –2.27, p = 0.02). By identifying gaps in the current literature and proposing directions for future research, this study hopes to inform the design of future PET studies aimed at quantifying alcohol‐induced dopamine release in the striatum of humans.

Cognitive Economics at Work
Authors: Caplin Andrew 
Published: December 2024

AbstractChapter 4 introduces cognitive labor economics. Inspired by the industrial revolution, standard production functions model the transformation of physical factors of production into physical outputs. With the growing importance of higher level decision-making skills, we need to model inputs as cognitive and outputs as improvements in decision quality. The chapter discusses how to amend human capital theory to capture the open-ended tasks that are increasingly important to earnings. The chapter also introduces recent research measuring and modeling economic decision-making skills based on the ability to apply the principle of comparative advantage. It introduces evidence that these skills help explain earnings from employment, and outlines ongoing research to track these effects in the Danish population registries.

Einlagenversorgung in der Therapie des Knicksenkfußes
Authors: Schmitt Alexander Pascal-Laurent , Liebau Kira-Henriette , Hamm Alexander , Mittelmeier Wolfram , Schulze Christoph 
Published: December 2024

Zusammenfassung

Hintergrund
Bei Erwachsenen erfolgt die Therapie des flexiblen symptomatischen Knicksenkfußes konservativ mit stützenden Einlagen, während sensomotorische Einlagen bei unzureichender Datenlage umstritten sind.

Fragestellung
Untersuchung der Wirksamkeit sensomotorischer und stützender Einlagen bei Erwachsenen.

Material und Methoden
Bei 73 Patienten wurden zusätzlich zu Fußgymnastik im Rahmen einer doppelt verblindeten, prospektiven, randomisierten placebokontrollierten Studie stützende, sensomotorische oder Placeboeinlagen unter Nutzung von Numerische Rating-Scala, Foot and Ankle Disability Index sowie Pedobarographie und Valgus-Index über 3 Messpunkte in einem Jahr miteinander verglichen. Die statistische Auswertung erfolgte mittels ANOVA mit Messwiederholungen.

Ergebnisse
Der Valgus-Index wurde bei stützenden Einlagen signifikant größer. Die Auflagefläche des Fußes konnte in der Verlaufskontrolle nur bei sensomotorischen Schuheinlagen in statischer und dynamischer Messung signifikant reduziert werden. Stützende Einlagen führten zu einer schnelleren Schmerzreduktion, jedoch ohne Reduktion der Auflagefläche. In der Funktionalität zeigten sich keine relevanten Unterschiede.

Schlussfolgerungen
Die Reduktion der Auflagefläche in Verbindung mit sensomotorischen Einlagen zeigt das Potenzial zur muskulären Adressierung des flexiblen Knicksenkfußes. Nachteile gegenüber anderen Versorgungen zeigten sich nicht. Stützende Einlagen führten schneller zur Reduktion von subjektiven Beschwerden, schwächen aber scheinbar die Fußwölbung-stützende Muskulatur. Längerfristig erscheint die konsequente Durchführung von Fußmuskeltraining ebenfalls wirksam zu sein, da auch das Tragen von Placeboeinlagen ohne signifikante biomechanische Änderungen zu einer Verbesserung des subjektiven Wohlbefindens führte.

Published: December 2024

Abstract
Temperate agroforestry practices offer various ecological, social, and economic benefits. However, data surrounding drivers of adoption for agroforestry in the U.S. remains limited. A survey of Missouri agricultural land managers was conducted to determine the extent of agroforestry adoption in the state, current knowledge and perceptions of agroforestry, and interest in implementing agroforestry practices. A choice experiment model was employed to assess participants’ willingness to accept (WTA) payment for adopting agroforestry practices and to determine land managers’ valuation of technical assistance and environmental benefits. Across the sample, self-reported knowledge of agroforestry practices was minimal to low (33%-78%). Perceptions of agroforestry systems for management and economic aspects were mixed, while promotion of biodiversity and environmental services were especially positive. Using a mixed logit regression model, if cost to establish a given agroforestry system was $2,500 per acre, it was determined that the average Missouri land manager would accept a per acre payment of $8,795 for alley cropping, $1,217 for forest farming, $3,080 for riparian forest buffers, $-3,546 for silvopasture, $11,458 for urban food forests, and $19,154 for windbreaks. WTA payments were lower for existing adopters of agroforestry than non-adopters. Among those who were willing to adopt agroforestry, technical assistance was valued at $1,670 per acre, while environmental benefits were valued at $2,992 per acre. In a second model testing interaction variables, participants with greater knowledge of agroforestry practices or with higher incomes were significantly more willing to adopt agroforestry practices, while participants with larger farms were less likely to adopt agroforestry.
On the vector subspaces of $$\mathbb {F}_{2^n}$$ over which the multiplicative inverse function sums to zero
Authors: Carlet Claude 
Published: December 2024

AbstractWe study the behavior of the multiplicative inverse function (which plays an important role in cryptography and in the study of finite fields), with respect to a recently introduced generalization of almost perfect nonlinearity (APNness), called kth-order sum-freedom, that extends a classic characterization of APN functions, and has also some relationship with integral attacks. This generalization corresponds to the fact that a vectorial function $$F:\mathbb {F}_2^n\mapsto \mathbb {F}_2^m$$

We study in the present paper the case of vector (i.e. linear) subspaces, which is much less simple to handle. The sum depends on a coefficient in subspace polynomials. We study for which values of k the multiplicative inverse function can sum to nonzero values over all k-dimensional vector subspaces. We show that, for every k not co-prime with n, it sums to zero over at least one k-dimensional $$\mathbb {F}_2$$

Phase Thermalization: from Fermi Liquid to Incoherent Metal
Authors: Banerjee Pinaki , Chakrabarty Bidisha , Mondal Swapnamay 
Published: December 2024

Abstract
When a system consists of a large subsystem (bath) and a small one (probe), thermalization implies induction of temperature of the bath onto the probe. If both the bath and the probe are described by same microscopic Hamiltonian, thermalisation further entails that the probe imbibes the phase of the bath. We refer to this phenomenon as phase thermalization. However, it is not clear whether this phenomenon is realizable when the probe and the bath are described by different microscopic Hamiltonians. We show phase thermalization is possible even when the microscopic Hamiltonians differ significantly. We provide an explicit example, where the probe is a Fermi liquid realised by a Majorana chain with

$$n \gg 1$$

fermions per site interacting through random hopping and the bath is an incoherent metal described by another Majorana chain with

fermions per site interacting through arbitrarily long range random four-fermion interaction. In deep infrared (i.e. at very low energies), the probe turns into an incoherent metal, with Lyapunov spectrum and diffusion coefficient identical to the bath.

Abstract
Efficient thermal management in microelectronic assemblies is crucial for the optimal performance and reliability of microprocessors. This study investigates the thermal, static, and creep performance of pressure-sensitive adhesives (PSAs) used in bonding heatsinks to microchips, focusing on the impact of adhesive coverage on thermal conductivity, mechanical strength, and long-term deformation under sustained loads. Shear loading, specifically analyzed due to the prevalence of shear stresses in vertically oriented microelectronic assemblies, is critical for understanding the long-term reliability of these bonds. The thermal analysis revealed that perfectly bonded heatsinks enhanced heat dissipation, with only a minor reduction in thermal conductivity observed due to incomplete adhesive coverage. Static tests demonstrated that perfectly bonded samples exhibited better load-bearing capacity overall, although joints with defects showed higher calculated stress due to the reduced bonded area at failure, with a 21% reduction in load-bearing capacity at room temperature and a 3.5% reduction at high temperature for joints with adhesive loss. Creep tests showed that at room temperature, the time to failure decreased by approximately 150% for samples with adhesive defects, while at high temperature, the reduction was over 66%. The study found that creep life is more sensitive to defects at lower temperatures, where adhesive loss has a more pronounced impact on performance. A predictive surface model was developed to estimate time to failure based on creep stress and temperature.
