The Enablers and Interdependencies of Blockchain Technology in Supply Chain Management: Evidence From Luxury Products
Authors: Quttainah Majdi Anwar , Singh Priya 
Published: August 2024

ABSTRACTBlockchain is a technology that combines a set of properties to guarantee network security, transparency, and visibility, including a decentralized structure, distributed notes and storage mechanism, consensus algorithm, intelligent contracts, and asymmetric encryption. Supply chain management activities, including supply chain management provenance, business process reengineering, and security enhancement, have enormous potential to be transformed by blockchain. This research uses the integrated interpretive structural modeling–cross‐impact matrix multiplication applied to classification (ISM‐MICMAC) technique to ascertain the hierarchical relationships and to comprehend the severity of interrelationships among various components in tackling our research questions. In MICMAC analysis, the enablers were classified into four categories based on their dependence and driving powers. The combined ISM‐MICMAC methodology employed for this study relies on experts’ individual evaluations and subjective assessments. Therefore, even with extreme caution, it is impossible to guarantee that the results are entirely devoid of personal biases. To further validate the linkages discovered in this study, we suggest employing more multiple‐criteria decision‐making (MCDM) methodologies and comparing the results with those of our research. Another method for confirming the results of the current study is to use an empirical research design based on survey methods.
Review: Impact of food safety on global trade
Authors: Tibebu Abebe , Tamrat Habtamu , Bahiru Adane 
Published: August 2024

AbstractFood safety encompasses the supply and assurance of safe, high‐quality food for consumers. It is a crucial aspect of food security, gaining greater global attention due to the increasing number of widespread foodborne incidents. International trade is expanding as countries increasingly rely on each other to secure a sufficient and diverse food supply. Beyond this, concerns about food safety have become more prevalent due to various factors. Therefore, this review aims to investigate the effects of food safety–associated risks on the international trade of food and related products. A total of 37 published studies retrieved using different search engines were included in this review. This review revealed that because of rapid population growth and rising food demand in developing nations, agricultural intensification is growing. It has been found that foodborne illnesses and associated discrepancies can impede the international trade of food commodities. Trade bans due to the fear of foodborne illnesses are growing. The consequences of foodborne diseases are multifaceted and include financial losses from trade restrictions, medical costs for prevention or control, resource depletion and a decline in food production. The overall effects are increased international trade tensions and livelihood vulnerability to poverty, notably for small‐scale livestock producers. Potential food contaminants include microbes, pesticides, pharmaceutical residues, heavy metals and fraudulent such as improper food processing, mislabelling, poor packaging, adulteration and substitution. Hence, countries are encouraged to harmonize the rights and duties set by the World Trade Organization under sanitary and phytosanitarys to maximize their advantages in global markets. Based on this evidence, we recommend that each country develop and integrate regulations that would ensure the safety of both domestic and international food production systems. Furthermore, the global community should either revise the current functioning food regulatory and monitoring body or establish a more genuine collaborative network.

Authors: Valūnaitė-Oleškevičienė Giedrė , Çavuşoğlu Ebru , Duarte Carlos 
Published: August 2024

AbstractWhile using technology to enhance teaching and learning, it is essential to make sure that none of the learners is excluded. Therefore, curriculum design should be done in such a way that it should not be left to students to adapt. This chapter focuses on the legal prerequisites officially applied in each researched country. According to the survey on the EU law on accessibility, the constitutions of Lithuania and Portugal foresee the availability of education for all citizens. Also, the currently available constitution in Turkey recognizes accessibility to education. Recently, the European Accessibility Act covered accessibility matters of products and services and requires legal adaptation in all the member countries, which lays a sound background for accessibility implementation in education. The current study analyzes the curricula of the translation courses of the Translation and Interpreting Department of Samsun University in Turkey, the Language Sciences Department of Lisbon University in Portugal, and the Institute of Humanities of Mykolas Romeris University in Lithuania by checking how the four main principles of digital accessibility (perceivable, operable, understandable, and robust) are observed in the existing curricula. The analysis identifies the need for practical recommendations in the analyzed curricula on how teaching and assessment methods could be applied to ensure fair and equal possibilities and observing the four key digital accessibility principles in the study process. The practical points should serve as a key factor for improving and creating curricula for technology-enhanced teaching and learning in translation studies.

A Multimodal Approach for Improving a Dialogue Agent for Therapeutic Sessions in Psychiatry
Authors: Gabor-Siatkowska Karolina , Stefaniak Izabela , Janicki Artur 
Published: August 2024

AbstractThe number of people with mental health problems is increasing in today’s societies. Unfortunately, there are still not enough experts (psychiatrists, psychotherapists) available. To address this issue, our research team developed a goal-directed therapeutic dialogue system named Terabot to assist psychiatric patients. This system features a voice interface, enabling verbal communication between the patient and the dialogue agent in Polish. Utilizing the RASA framework, the dialogue system is enhanced with text-based emotion and intention recognition. This enables the dialogue system to react “empathically,” i.e., considering the patient’s emotions. The purpose of Terabot is to provide extra support for mental health patients who require additional therapy sessions due to limited access to medical personnel. This will not replace drug treatment but rather serve as additional therapy sessions. Our study consisted of therapy sessions of patients talking to Terabot, conducted at the Institute of Psychiatry and Neurology in Warsaw, Poland. During these sessions, we observed several issues that have led either to interrupting the therapeutic session or worsening the patient’s performance of the relaxation exercise. We suggest addressing these problems by implementing an eye-tracker in our dialogue system to make the dialogue flow more human-like. We propose a feedback loop in which the eye-tracker provides essential data back to the RASA framework. This gives additional information to the framework, and a more appropriate response can be given to the patient. Our main aim is to establish a feedback loop that will likely impact the way the conversation is conducted. Thanks to this, the dialogue system may perform better. As a result, the dialogue agent’s responses can be improved, resulting in a more natural, human-like flow of conversation.
Contemporary Art and Audio Accessibility from Translation Studies: An Essential Binomial in Current Artistic Creations
Authors: Pérez de Zafra Arrufat María Asunción , Domínguez Escalona David 
Published: August 2024

AbstractBioArt is an interdisciplinary research project that focuses on contemporary art. It aims to advance the field of universal accessibility in experimental artistic spaces, emphasizing multisensory experiences. Utilizing a phased methodology that includes a literature review and sensory element analysis, the project identifies innovative practices for creating accessible multisensory exhibitions. In collaboration with researchers and artists with and without disabilities, the exhibition aims to blur the boundaries of the conventional concert hall and exhibition room by creating experimental visual and sound works based on the analysis of movement patterns in individuals with permanent or temporary disabilities, such as Parkinson's disease tremors or spinal cord injuries. Bioart will offer accessible experiences targeting diverse groups, such as visitors with hearing impairments. This chapter explores the barriers present in contemporary exhibitions and addresses them by implementing alternative accessibility measures for the deaf and hard of hearing. These measures include vibrating backpacks to translate the music track played in the room's soundscape, sign language translation, easy-to-read displayed information, and multichannel information. Contemporary art can provide fully accessible experiences for deaf and hard-of-hearing visitors when considering them from the concept design, even if the sound is a key concept. For this purpose, new approaches and accessibility solutions have to be considered to translate the sound experience through other channels (haptic, visual, or the sense of smell). Expected benefits include empowering attendees with diverse abilities, fostering social inclusion, and inspiring future international endeavors in the realm of accessible contemporary arts.
Comb channel lightcone bootstrap: triple-twist anomalous dimensions
Authors: Harris Sebastian , Kaviraj Apratim , Mann Jeremy A. , Quintavalle Lorenzo , Schomerus Volker 
Published: August 2024

Abstract
We advance the multipoint lightcone bootstrap and compute anomalous dimensions of triple-twist operators at large spin. In contrast to the well-studied double-twist operators, triple-twist primaries are highly degenerate so that their anomalous dimension is encoded in a matrix. At large spin, the degeneracy becomes infinite and the matrix becomes an integral operator. We compute this integral operator by studying a particular non-planar crossing equation for six-point functions of scalar operators in a lightcone limit. The bootstrap analysis is based on new formulas for six-point lightcone blocks in the comb-channel. For a consistency check of our results, we compare them to perturbative computations in the epsilon expansion of ϕ3 and ϕ4 theory. In both cases, we find perfect agreement between perturbative results and bootstrap predictions. As a byproduct of our studies, we complement previous results on triple-twist anomalous dimensions in scalar ϕ3 and ϕ4 theory at first and second order in epsilon, respectively.
Electric dipole moments of charged leptons in models with pseudo-Dirac sterile fermions
Authors: Abada Asmaa , Toma Takashi 
Published: August 2024

Abstract
In this work, we address the impact of a small lepton number violation on charged lepton electric dipole moments — EDMs. Low-scale seesaw models protected by lepton number symmetry and leading to pseudo-Dirac pairs in the neutrino heavy spectrum provide a natural explanation for the smallness of neutrino masses with potentially testable consequences. Among which, it was thought that the small mass gap in each pair of pseudo-Dirac neutrinos may induce important contribution to the charged lepton EDMs. Recently, it has been shown that the contribution from some of the Feynman diagrams to charged lepton EDMs exactly cancel by virtue of the Ward-Takahashi identity in quantum electrodynamics. We thus consider here the Standard Model minimally extended with pairs of pseudo-Dirac sterile fermions and derive the complete analytical formula at two loops for the charged lepton EDMs. In addition, we numerically evaluate the order of the predicted EDMs consistent with the experimental bounds and constraints such as neutrino oscillation data, charged lepton flavour violating processes, sterile neutrino direct searches, meson decays, sterile neutrino decays, and cosmological and astrophysical observations. We find that, in the minimal setup accommodating neutrino data (masses and mixings) with only two pseudo-Dirac pairs, the predicted electron EDM is $$ \mathcal{O}\left({10}^{-36}\right) $$

e cm, at most, which is much smaller than the current experimental bound and even future sensitivity. Hopefully, the electron EDM might reach future sensitivity, once extra pseudo-Dirac neutrinos are taken into account. The analytical formulae we derive are generic to any model involving pseudo-Dirac pairs in the heavy neutrino spectrum.
On gauge amplitudes first appearing at two loops
Authors: Dixon Lance J. , Morales Anthony 
Published: August 2024

Abstract
We study scattering amplitudes in massless non-abelian gauge theory where all outgoing gluons have positive helicity. It has been argued recently by Costello that for a particular fermion representation (8 fundamentals plus one antisymmetric-tensor representation in SU(N)) the one-loop amplitudes vanish identically. We show that this vanishing leads to previously-observed identities among one-loop color-ordered partial amplitudes. We then turn to two loops, where Costello has computed the all-plus amplitudes for this theory, as rational functions of the kinematics for any number of gluons using the celestial chiral algebra (CCA) bootstrap. We show that in dimensional regularization, these two-loop amplitudes are not rational, and they are not even finite as ϵ → 0. However, the finite remainder for four gluons agrees with the formula by Costello. In addition, we provide a mass regulator for the infrared-divergent loop integrals; with this regulator, the CCA bootstrap formula is recovered exactly. Finally, we use the CCA bootstrap to compute the double-trace terms in the theory at two loops for an arbitrary number of gluons.

orientifold via a machine-learning approach. We apply several autoencoder models with and without positional encoding to D6-brane configurations satisfying certain concrete models described in ref. [1] and attempt to extract some features which the configurations possess. We observe that the configurations cluster in two-dimensional latent layers of the autoencoder models and analyze which physical quantities are relevant to the clustering. As a result, it is found that tadpole charges of hidden D6-branes characterize the clustering. We expect that there is another important factor because a checkerboard pattern in two-dimensional latent layers is observed in the clustering.
Symmetric and Dual PRFs from Standard Assumptions: A Generic Validation of a Prevailing Assumption
Authors: Bellare Mihir , Lysyanskaya Anna 
Published: August 2024

AbstractA two-input function is a dual PRF if it is a PRF when keyed by either of its inputs. Dual PRFs are assumed in the design and analysis of numerous primitives and protocols including HMAC, AMAC, TLS 1.3 and MLS. But, not only do we not know whether particular functions on which the assumption is made really are dual PRFs; we do not know if dual PRFs even exist. What if the goal is impossible? This paper addresses this with a foundational treatment of dual PRFs, giving constructions based on standard assumptions. This provides what we call a generic validation of the dual PRF assumption. Our approach is to introduce and construct symmetric PRFs, which imply dual PRFs and may be of independent interest. We give a general construction of a symmetric PRF based on a function having a weak form of collision resistance coupled with a leakage hardcore function, a strengthening of the usual notion of hardcore functions we introduce. We instantiate this general construction in two ways to obtain two specific symmetric and dual PRFs, the first assuming any collision-resistant hash function and the second assuming any one-way permutation. A construction based on any one-way function evades us and is left as an intriguing open problem.
Buyers’ welfare maximizing auction design: comment
Authors: Knyazev Dmitriy 
Published: August 2024

AbstractIn an earlier paper published in this journal, Bauer (2023) claims to have constructed an auction format that maximizes buyers’ welfare. We note that the characterization of such a mechanism in Proposition 1 of Bauer (2023) is incomplete because it does not precisely specify the payment rule. Because of that, the discussion following this proposition is misleading and the mechanism proposed in the example is not incentive compatible. The complete characterization of the optimal mechanism is the one from Krishna and Perry (1998).
Development and validation of the UHPLC-MS/MS method for the quantitative determination of 25 PFAS in dried blood spots
Authors: Galletto Martina , Ververi Christina , Massano Marta , Alladio Eugenio , Vincenti Marco , Salomone Alberto 
Published: August 2024

AbstractPer- and polyfluoroalkyl substances (PFAS) are anthropogenic fluorine-containing compounds largely used in industrial and consumer applications. They tend to bioaccumulate in the human body after intake from various sources in daily life. Following repeated exposure to PFAS, a broad range of adverse health outcomes has been reported. Consequently, monitoring PFAS levels in human blood is of paramount importance for public health policies. In contrast with traditional venipuncture, dried blood spots (DBS) constitute a reliable, cheap, and less invasive technique to allow microsampling by capillary blood collected on a specific device. This work aimed to develop and validate an innovative analytical method, combining quantitative DBS with UHPLC-MS/MS instrumentation to identify and quantify 25 PFAS. The extraction procedure was developed and optimized within the range 2–100 ng/mL. Specifically, fortified blood was applied on Capitainer®B devices providing 10 μL of blood volume through a microfluidic channel. After 3 h of drying, the extraction was performed by methanol under sonication, followed by centrifugation. Then, the extraction solvent was evaporated; the residue was reconstituted with the mobile phase solution. The validated method evidenced good sensitivity, with limits of detection ranging from 0.4 ng/mL (PFODA, PFOS) to 1.0 ng/mL (PFOA, 3,6-OPFHpA). The ± 20% acceptability criteria established for intra- and inter-day precision and accuracy were fulfilled for all analytes. High recovery—above 80%—was recorded, whereas significant matrix effect resulted in ion enhancement (> 50%) for 13 analytes. In conclusion, the proposed workflow proved to be reliable, fit for purpose, and easily adaptable in the laboratory routine.

Heat vulnerability: health impacts of heat on older people in urban and rural areas in Europe
Authors: Fastl Christina , Arnberger Arne , Gallistl Vera , Stein Viktoria K. , Dorner Thomas E. 
Published: August 2024

SummaryExposure to extreme heat is associated with both increased morbidity and mortality, especially in older people. Health burdens associated with heat include heat stroke, diabetes mellitus, hypertension, ischemic heart diseases, heart failure and arrhythmia, pulmonary diseases but also injuries, problems with activities of daily living, and mental disorders. In Europe, there are remarkable spatial differences in heat exposure between urban and less populated areas. In Austria, for example, there is a significant gradual association between population density and the number of heat days, where the gradient of urbanization also follows the gradient of sea level. The European population is continuously ageing, especially in rural areas. Older adults are especially vulnerable to negative health consequences resulting from heat exposure, due to a lack of physiological, social, cognitive, and behavioral resources. Older people living in urban areas are particularly at risk, due to the urban heat island effect, the heat-promoting interplay between conditions typically found in cities, such as a lack of vegetation combined with a high proportion of built-up areas; however, older people living in rural regions often have less infrastructure to cope with extreme heat, such as fewer cooling centers and emergency services. Additionally, older adults still engaged in agricultural or forestry activities may be exposed to high temperatures without adequate protection or hydration. More research is required to examine factors responsible for heat vulnerability in older adults and the interactions and possibilities for increasing resilience in older urban and rural populations to the health consequences of heat.
