Authors: Zhang Yichao , Zhou Yang
Published: July 2023

Over any fixed totally real number field with narrow class number one, we prove that the Rankin-Cohen bracket of two Hecke eigenforms for the Hilbert modular group can only be a Hecke eigenform for the dimension reason, except for a couple of cases where the Rankin-Selberg method does not apply. We shall also prove a conjecture of Freitag on the volume of Hilbert modular groups, and assuming a conjecture of Freitag on the dimension of the cuspform space, we obtain a finiteness result on eigenform product identities.

Accelerating equilibrium spin-glass simulations using quantum annealers via generative deep learning
Authors: Scriva Giuseppe , Costa Emanuele , McNaughton Benjamin , Pilati Sebastiano
Published: July 2023

Adiabatic quantum computers, such as the quantum annealers commercialized by D-Wave Systems Inc., are routinely used to tackle combinatorial optimization problems. In this article, we show how to exploit them to accelerate equilibrium Markov chain Monte Carlo simulations of computationally challenging spin-glass models at low but finite temperatures. This is achieved by training generative neural networks on data produced by a D-Wave quantum annealer, and then using them to generate smart proposals for the Metropolis-Hastings algorithm. In particular, we explore hybrid schemes by combining single spin-flip and neural proposals, as well as D-Wave and classical Monte Carlo training data. The hybrid algorithm outperforms the single spin-flip Metropolis-Hastings algorithm. It is competitive with parallel tempering in terms of correlation times, with the significant benefit of a much shorter equilibration time.
Bloch-Lorentz magnetoresistance oscillations in delafossites
Authors: Vilkelis Kostas , Wang Lin , Akhmerov Anton R.
Published: July 2023

Recent measurements of the out-of-plane magnetoresistance of delafossites (PdCoO_22 and PtCoO_22) observed oscillations closely resembling the Aharonov-Bohm effect. Here, we show that the magnetoresistance oscillations are explained by the Bloch-like oscillations of the out-of-plane electron trajectories. We develop a semiclassical theory of these Bloch-Lorentz oscillations and show that they are a consequence of the ballistic motion and quasi-2D dispersion of delafossites. Our model identifies the sample wall scattering to be the most likely factor limiting the visibility of these Bloch-Lorentz oscillations in existing experiments.
Consumer engagement in the conditions of business digitization: A case study of the hotel industry in Ukraine
Authors: Boiko Margaryta , Kulyk Mariia , Bondar Svitlana , Romanchuk Liudmyla , Lositska Tetiana
Published: July 2023

Competition in the hotel industry makes it necessary to study innovative ways to preserve and increase customer base. Effective interaction with customers is evidence of hotels’ innovative activity determined by the active implementation of marketing concepts and the development of information technologies. Therefore, customer engagement involves digitalizing the “hotel-consumer” interaction process. This study aims to determine the components of digital customer engagement in the hotel industry using systematization, generalization, survey, and econometric models. The components of digital customer engagement include recognition, interest, communications, consumer experience, loyalty, and intentions of repatronage. Econometric models used the data of hotels in Kyiv (Ukraine) to prove the dependence of their income on the costs of digital consumer engagement. For financial indicators, the study surveyed hotel managers and stakeholders. The selected indicators have a significant influence on hotel income. In the case of a linear model (“Khreshchatyk” hotel), the parameters show how many units the effective feature will change when one-factor characteristic changes by one unit (assuming other factors are constant). In the case of power-law models (“Bratislava” and “Ukraine” hotels), the parameters are essentially elasticity coefficients that demonstrate the sensitivity of income changes to changes in factor characteristics. Accordingly, the coherence of implementation of all components in the digital engagement of hotel services’ consumers ensures an increase in service provision volume and hotel operations’ efficiency.

Landscape fragmentation constrains bumblebee nutritional ecology and foraging dynamics
Authors: Pioltelli Emiliano , Guzzetti Lorenzo , Larbi Malika Ouled , Labra Massimo , Galimberti Andrea , Biella Paolo
Published: July 2023

Habitat fragmentation is modifying landscapes and the distribution of
floral resources, possibly shaping also pollinator resource acquisition.
Here, using urban parks as field laboratories for the dramatic contrast
around, we aimed to clarify how fragmentation and local flower
availability shape bumblebee foraging dynamics by characterizing several
components: the nutritional content and plant composition of collected
pollen pellets, the foraging rate and the plant-nutrition association
along a fragmentation gradient. We found mostly negative linear or
non-linear relationships between nutritional quality and fragmentation,
tight plant composition-nutrition associations interpretable as low
access to alternative resources, and shorter foraging time in smaller
green areas, showing behavioral limits by the landscape. Thus,
fragmentation can constrain all aspects of bumblebee foraging by
compromising resource accessibility. This study illuminates the link
between landscape features and the nutritional ecology of pollinators, a
key aspect for understanding pollinator foraging dynamics and even for
outlining mitigation measures in urban contexts.

O objetivo desta pesquisa é analisar uma experiência pedagógica realizada com estudantes do Ensino Fundamental (séries iniciais) por meio de duas oficinasaulas durante o período de setembro e outubro de 2015, no sentido da educação para o lazer e numa perspectiva cultural. Quando os sujeitos são incentivados a consumir produtos tecnológicos, como jogos e brinquedos, nem sempre têm a oportunidade de refletir sobre os modos de sua utilização, o que acaba por impedir a criação de formas diferentes de brincar, assim como, de novos brinquedos. Nesta pesquisa, desenvolveu-se uma investigação bibliográfica e de campo, do tipo participante e de natureza qualitativa. Os dados foram registrados em diário de campo e foi feita uma análise interpretativa com o intuito de identificar os significados do brincar para os participantes da pesquisa. Os resultados demonstraram que os estudantes gostaram de brincar com os brinquedos que eles construíram a partir de materiais recicláveis pelo fato de eles mesmos terem montado esses brinquedos e pela possibilidade de realizar diferentes brincadeiras com os objetos construídos.
A Modified Hybrid Objective Model to Calculate the Weights of Cause and Effect Criteria in a System: DEMATEL and DEVELOPED SWARA (D-DS) Based Model
Authors: Ebrahimi Seyed Hossain
Published: July 2023

Criteria weighting is a widely used and also an important feature of multi criteria decision making problems specially in engineering, computer science and management investigations. In particular in many studies related to complex systems there would be usually two main groups of cause and effect criteria. In this research it is intended to make an hybrid objective model comprising DEMATEL and SWARA techniques to assign classified weights to the subgroup of cause and effect criteria. As a main goal, the proposed hybrid model in this presented paper can afford to assign greater values for criteria who belong to cause group. In this regard we apply the objective information which derived from the parameters of (R, equal to sum of direct and indirect influence of a criteria), (R/C, named as net influence power of a criteria) and (R-C, named as net effect of a criteria) related to the final total influence matrix T in DEMATEL methodology. The main contribution in this work lies in utilizing the SWARA methodology and making us of its revision where the relatively Comparative ImportanceSj, applied in SWARA technique is reconfigured by some aggregation operators includingmax,EinsteinandHamacheroperators for obtaining more uniformed weights of cause and effect criteria relatively to SWARA basic methodology. Finally results shows that the (R/C) and (R-C)would transfer more clear and refined data and numeric information achieving better and highly reliable weights of criteria categorized into two groups of cause and effect group.

The emergence and popularisation of so-called social media have enhanced the militancy of the most diverse groups, including terrorist ones. This article problematises international terrorism, pointing out the causes and effects of this 21st-century phenomenon that we name cyberterrorism 2.0. Thus, we focus on the cyberterrorism studies that analyse social media usage's inputs and outputs by terrorist groups. Through Webometrics and the framework Stakeholders, Activities and Motives in the realm of cybersecurity (SAM), we aim to explain, in the light of International Security Studies and through the Islamic State case study, how cyberterrorism 2.0 arises, develops and impacts national security.
THE BRAZILIAN ARMY’S CONCEPT OF TRANSFORMATION: TECHNOLOGY AND MILITARY CHANGE
Authors: Teixeira Júnior Augusto W. M. , Gama Neto Ricardo Borges
Published: July 2023

Since the National Defense Strategy (NDS) publication, the Brazilian Army has sought to respond to the challenges of raising its standards to those of the Knowledge Age. BRAÇO FORTE Strategy, PROFORÇA, and the Army's Strategic Projects are examples of necessary steps towards the desired military change. However, does the Army's concept of Transformation express an understanding of Military Transformation, or does it fall into the trap of technological determinism? Our hypothesis states that possible failures of the Army's Force Project are a product of a reductionist understanding of Transformation. Despite using the term Transformation, the assumptions that support the Army's Transformation process predominantly imply improving what it already does. Excepting projects such as Cyber Defense, SISFRON, and ASTROS 2020, modernization is more present than Transformation as military change. The paper used a Case Study research design methodology. Qualitative sources such as documents from the Ministry of Defense and the Brazilian Army were analyzed using a document analysis strategy named internal comparison criteria.

Farmasötiklerin sucul çevrelere ulaşmasındaki önemli kaynaklardan bir tanesi atıksu arıtma tesisi deşarjlarıdır. Bu çalışmada, Konya kenti kanalizasyon sisteminde bazı analjezik ve anti-enflamatuarın varlığı ve konsantrasyonu, Konya Atıksu Arıtma Tesisin (AAT)’de bu farmasötiklerin giderimi belirlenmiştir. AAT deşarjı ile alıcı ortama deşarj edilen farmasötiklerin oluşturduğu ekotoksikolojik risk balık, Daphnia magna ve alg için değerlendirilmiştir. Kanalizasyon sisteminin 22 farklı noktasından ve ATT giriş-çıkışından alınan örneklerin ekstraksiyonu katı faz ekstraksiyonu ile, farmasötiklerin kalitatif ve kantitatif analizleri ise sıvı kromatografisi kütle spektrometresi (LC-MS/MS) ile gerçekleştirilmiştir. Kanalizasyon sisteminde etodolac 3875 ng/L, diclofenac 119 ng/L, flurbiprofen 247912 ng/L, naproxen 1827 ng/L, paracetamol 7204 ng/L, propyphenazone 2.23 ng/L ortalama konsantrasyonlarında tespit edilmiştir. AAT giriş ve çıkışında ise sırasıyla etodolac 5080 ng/L ve 19688 ng/L, diclofenac 248 ng/L ve 962 ng/L, naproxen 1924 ng/L ve 97.7 ng/L, paracetamol 3286 ng/L ve 109 ng/L, propyphenazone 7.3 ng/L ve 20.9 ng/L ortalama konsantrasyonlarında tespit edilmiştir. AAT’de naproxen, paracetamol farmasötikleri için %90 üzerinde giderim gözlenmiş, diğer farmasötiklerin tesiste giderilemediği görülmüştür. Çıkış atıksuyunda tespit edilen konsantrasyonlar ile yapılan risk değerlendirmesinde alıcı ortam için önemsiz risk tespit edilmiştir. Buna rağmen, farmasötiklerin alıcı ortamlarda bulunan tek kirletici olmadığı, konvansiyonel ve diğer mikrokirleticilerle bir arada bulunduğu, hepsinin ayrı ayrı toksik etkileri birleştiğinde ciddi çevresel sorunlar oluşturabileceği unutulmamalıdır. Ayrıca, farmasötikler çevresel ortamlarda ve canlı dokularda birikebilir, besin zincirine taşınabilir.

Electrical Impedance Tomography (EIT) is a technology that uses recorded voltage data to reconstruct thedistribution of electrical conductivity in a turbid medium and to illustrate the structures and abnormalities within that medium. The advantages of this imaging technology include non-ionization, non-invasive, impact and continuous monitoring, optimum design, and lower production costs as compared to current techniques such as Magnetic Resonance Imaging (MRI), Computed Tomography Scan (CT- Scan), and Ultrasonic... EIT has shown useful in a variety of medical domains, including identifying pneumothorax, assessing pulmonary edema, and evaluating ventilation distribution between different breathing modes. TheEIT is also being studied for application for imaging reconstruction used to obtain images for medical imaging, geological exploration, industrial application and environmental sciences. In this research, a system of 16 electrodes is manufactured for simulate biological tissue using ground pork to simulate the internal environment of the human body. The confirmed experiments are carried out using a phantom while the frequencies between 10kHz to 100 kHz are changed. An Arduino and a PC are used to collect and process the measured data. Electrical Impedance Tomography and Diffusion-based Optical Tomography (EIDORS) software is used to recreate the cross-sectional image. The image reproduced at 100 kHz gives high accuracy to the reconstructed subject.

Published: July 2023

One advantage of light-based technology is that it offers non-intrusive analysis. By comprehending how light interacts with food’s tissue and examining how it is absorbed and reflected. Multispectral Camera Model (MCM) can rapidly evaluate the food quality without physically destroying it. In this work, the capturing system model that is used to evaluate the quality of food is discussed. The Raspberry Pi 4 serves as the primary controller for the MCM, controlling the LEDs and camera. The MCM contains LEDs with four color modes with spectroscopy carried out in the VIS-NIR bands which are Red (620 – 625nm), Green (522 – 525nm), Blue (465 – 467nm) and Near-IR (peak wavelength in 940nm). One at a time, specific wavelength LEDs are individually illuminated, and for each flash, a sample is simultaneously taken with a Raspberry Camera. The result is that every image captured will be represented as a 3-dimensional data cube containing details of both spectral and spatial space.

Published: July 2023

Production of pork is a daily objective for both producers and consumers. Pork quality and its economic advantages can be enhanced by using quick, non-destructive, and inexpensive monitoring techniques. This study investigates the potential of using international photos to monitor pork quality. Image processing is done using the ROI- based processing, and then using a specific algorithm for food quality assessment. This allowed structural characteristics to be retrieved from the several photos of flesh tissue. A monochrome camera and four sets of optical filters covering the red (625 nm), green (525 nm), blue (465 nm), and near-IR (940 nm) spectra were employed in this work. In this research, the use of multispectral imaging and chemometrics combined modeling is validated as a non-destructive, quick, low-cost quality control tool that can effectively monitor pork quality. This offers a scientific foundation for the next study and creation of broadly applicable devices for both assessing pork quality and multispectral imaging techniques.

Published: July 2023

The patient experiences trouble walking and surviving as a result of tibia fractures or tibial osteoporosis. The tibia, a crucial bone in the lower extremities that requires the longest recovery time, as well as the relatively low level of activity in the legs, are both factors. In the patient's day-to-day existence, this has a substantial effect. Regenerating tissue, reducing pain, and reducing inflammation are all effects of low-level laser light. In this work, the effects of lasers of four different wavelengths—633 nm, 780 nm, 800 nm, and 940 nm—were examined using the Monte Carlo approach. We put the curve fitting technique into practice using the parameters we learned from the outcomes of the many Monte Carlo simulations. With an RSME of 2.62% and 1.32%, respectively, the findings demonstrated the link between energy and beam radius with regard to depth. We anticipate that the study will provide a quick analysis of how laser beams affect different regions in order to improve treatment settings.

Published: July 2023

In the musculoskeletal system, the spine determines the life and movement of humans as well as that of all other vertebrates. The degenerative spine usually begins with damaged joints of the vertebral bodies, neck herniated disc, ligament, and then gradually occurs degeneration of the vertebrae, causing neck pain, especially when moving the neck area.

Nowadays, along with the development of the biomedical field, low-power laser therapy is more prominent in its applicability in diagnosis and treatment. This paper describes the simulation results of low-level laser propagation from the skin surface to the cervical vertebrae with four wavelengths (633 nm, 780 nm, 850 nm, and 940 nm) by the Monte Carlo method. These simulation results are the base for analyzing the impact of near-infrared light and developing a low-level laser therapy device, that could be used clinically for treating the degenerative spine.

Despite the limited knowledge of light propagation in foods, optical techniques are becoming more common in the evaluation of food quality. Using the Monte Carlo technique, we model light propagation in pork tissue in this research. Since then, researchers have been examining how light moves through pork tissue and how multispectral imaging methods may use this information. Light can penetrate deep into the food tissue in the range of wavelength examined in this paper. The purpose of this study is to simulate the signal reception, select the appropriate wavelengths and the signal acquisition mode. The simulation results offer a general structure for system design and the creation of optically based food quality assessment tools.

Authors: Mohajer Rhett-Lawson , Zolnikov Tara Rava
Published: July 2023

Research shows that clinicians use music, either as music therapy or as an adjunct to talk therapy, in providing treatment to patients with a history of trauma, ones struggling with depression and anxiety, as well as in treating patients whose diseases have organic etiologies. However, the endopsychic structural permutations as the result of encountering music are understudied. The unique qualities of psychoanalysis mean researchers can use it as a tool to study unconscious transmutations and processes. The purpose of this phenomenological qualitative research was to understand the endopsychic structure changes during and after music improvisation based on the subjective experiences of 20 adult individuals. The researcher used unstructured interviews. The results show that participants moved toward partial ego positions during improvisation and felt whole after the intense moments of improvisation that involved the experience of heightened emotions.

The point of sale (POS) system is not something foreign to prominent entrepreneurs, this system has long been used by large-scale business actors, but generally, a system like this has complex features and its operation requires special personnel, therefore in the all-digital era Currently, there are still many small entrepreneurs using traditional processes in managing their businesses due to limited access to technology and costs, this will undoubtedly take time and reduce business productivity compared to using modern management systems. Then we need a POS that is easier to access and does not require large costs by small or medium-scale businesses, because it will be the right solution for business management with a lot of manual work automated by the system, such as profit and loss calculations, information on the availability of goods, information on quantities goods, and transaction processes using a scan code where the total payment and change will be calculated automatically by the system, of course with the presence of this point of sale system it will make it easier for small and medium business actors because the system is available in the form of mobile application which can be accessed easily by many business groups.

College students are the human capital of a nation, and their college education lays the foundation for their success as future leaders of society. However, their ability to advance is often impeded by stress. Changes in lifestyle, increased academic workload, student debt, forming interpersonal relationships, and coping with new adult responsibilities may result in clinically significant anxiety and depression that require medical attention. Left untreated, these illnesses hinder academic progress and decrease graduation rates. College students constitute a highly mobile population frequently traveling for breaks and school-related activities and, as such, at increased risk of interruption and/or discontinuation of care.

The COVID-19 pandemic challenged our ability to offer consistent mental health care for students and forced us to implement public health measures that were long overdue. Temporary governmental policy changes allowing for the provision of remote care across state lines at the same reimbursement rate as in-person services were vital to student mental health recovery, retention in school, and graduation rates. The time-limited loosening of state-based medical licensure restrictions clearly demonstrated the feasibility, benefits, and dire need for widespread implementation of telehealth. These are important lessons that should inform future policies for student health.

In this paper, we advocate therefore, that the temporary loosening of the licensure restrictions and equitable reimbursement rates be codified into law. The current licensing regulations have not kept pace with the lived experience of college students or modern society in general. Given more mobile lifestyles, these restrictions result in frequent inevitable transitions of care which are highly undesirable. Even if providers outside metropolitan areas were readily available,1,2 these transitions of care are fraught with considerable risk for medical error. We also advocate for a national standardization of tele-psychiatry policy and procedures, including access to electronic health care records for providers taking care of matriculated students. To date, student mental health services are a patchwork of organizational models of varying funding and efficacy.
A Pathway to Liberation: A History of the Freedom Schools and the Long Struggle for Justice Since 1865
Authors: Hale Jon
Published: July 2023

The Freedom School Movement originated at the nexus of the struggles for liberation and full citizenship. Beginning with the articulation of education as a means to freedom during the era of slavery, the ideology behind Freedom Schools was an integral aspect of the long Black freedom struggle in the US. These Schools have continually recognized the integral role and contribution of Black activists and educators who, throughout the course of the United States’ history, have historically provided a counternarrative to White supremacy and racist policy through education grounded in the needs, aspirations, and wisdom of local community organizing.
Methodology for Accounting the Influence of Parameters of a Spherical Underlying Surface with Finite Conductivity on VLF Antennas Characteristics
Authors: Tipikin A. , Potapov D.
Published: July 2023

The Earth's underlying surface has a significant impact on the characteristics of antennas and the energy parameters of the radio path. Although the theoretical aspects of the influence of the finite conductivity of the underlying surface on antennas have been sufficiently studied, there is a need for the development of a specific methodology that would allow to automize energy parameters calculations of radio paths using the wavehop method. This article presents a methodology for accounting for the electrical characteristics of the subsoil surface, which differs in its ability to use digital maps and automate calculations. It also includes separate calculation results for correcting antenna coefficients that confirm the theoretical calculations. The developed methodology can be used for calculations of energy parameters of radio paths using the wavehop method.
