Authors: Pareja Monturiol José Ramón , Pérez-García David , Pozas-Kerstjens Alejandro
Published: June 2024

Tensor networks are factorizations of high-dimensional tensors into networks of smaller tensors. They have applications in physics and mathematics, and recently have been proposed as promising machine learning architectures. To ease the integration of tensor networks in machine learning pipelines, we introduce TensorKrowch, an open source Python library built on top of PyTorch. Providing a user-friendly interface, TensorKrowch allows users to construct any tensor network, train it, and integrate it as a layer in more intricate deep learning models. In this paper, we describe the main functionality and basic usage of TensorKrowch, and provide technical details on its building blocks and the optimizations performed to achieve efficient operation.

Authors: Komalova Liliya R.
Published: June 2024

Due to the increased pace of digitalization in all areas of life, including medicine, more citizens can receive qualified medical care. The period of the СOVID-2019 pandemic has clearly demonstrated that telemedicine is becoming a relevant area of medical practice. In particular, the role of online consultation in medical communication is significantly increasing. In this regard, medical network discourse becomes the focus of scholarly interest. Our research is aimed at verifying the scenario of medical consultations on medical online forums. The research material includes 5259 messages in Russian from 2018-2023 as part of 60 medical consultations on cardiology on rusmedserv Internet forum. The empirical study design included the collection and structuring of research material by means of corpus methods; the data were described, systematized and generalized; the qualitative interpretation of the data was carried out on the basis of the communicative and pragmatic method of analysis developed by Issers (2008). It was found that the dynamics and structure of medical consultations are generally maintained while a doctor and a potential patient are interacting through an Internet forum. The obtained data also confirm the findings presented in academic literature on “doctor - patient” communication via Internet forums. The results of the research contribute to the understanding of written medical Internet consultation proving that it unfolds inconsistently, but recurrently; the communication innovations mainly relate to the dynamics of communication scenario during medical Internet consultation deployment. The obtained results may contribute to the development of a more effective “patient - doctor” communication model focused on the mission of telemedicine.

An experiment was performed to assess the effect of two plant powders and six storage methods on the proximate composition of potato tubers stored under ambient conditions to find a simple technology for storing potato tubers with a minimal nutrient degradation to reduce postharvest losses by smallholder farmers. Two plant powders and six storage methods were used in the study, which was designed as a 3 x 6 factorial experiment laid out in a completely randomized design (CRD) and replicated three times. The application of neem leaf powder to potato tubers and storage in the pit significantly (P ≤ 0.05) maintained protein (5.65%), fat (0.91%), fiber (0.75%), ash (2.70%), dry matter (30.63%), moisture (69.34%), and carbohydrate (20.62%) contents. Similarly, the pit storage method has influenced the nutrient content significantly (P ≤ 0.05) and is the best method for retaining protein (5.74%), fiber (0.78%), ash (2.81%), and moisture (69.83%) contents of potato tubers during storage under ambient conditions, and there is no significant (P > 0.05) interaction effect between the plant powder and the storage method. The study has found that the neem leaf powder and the pit storage significantly preserved the nutrient content of potato tubers during the four weeks of storage, which helped minimize postharvest losses.

On motivation and enterprise education – ensuring manageable goals and objectives
Authors: Isle Timothy , Mostert Andre
Published: June 2024

There is growing recognition that the standard approach to motivation, referred to as Motivation 2.0 is not necessary adequate for assessing the contemporary drivers for students and budding entrepreneurs. Some have argued that the concept of goal setting may act as much as an inhibitor as a motivator. This perspective on goal setting can, prima facie, be very relevant to the entrepreneurial educator. In this research exercise the contemporary thinking on motivation and motivational approached will be explored and applied to the development of entrepreneurial education curriculum development and pedagogic structures. Those entrusted with the nurturing and development of any innate entrepreneurial potential must ensure that the teaching and learning environment is dynamic and as individualized as possible. Key to any individualized delivery mechanism is a coherent understanding of motivational factors and activities. Effective curriculum development for entrepreneurial training demands an integrated understanding of motivators which must be driven extracurricular, while enterprise education continues to become embedded in educational delivery structures. This paper addresses these demands and acts as a primer for how this could be achieved.

Published: June 2024

A novel tungsten carbide (WC)-reinforced nickel (Ni)-based laser cladding layer was prepared through an in-situ synthesis process. The influence of different concentrations of CeO2/Y2O3 on the microstructure, wear, and corrosion resistance of the in-situ synthesized WC-reinforced Ni-based cladding layer was analyzed. The results revealed that the coatings doped with rare-earth oxides exhibited good micro-hardness (660 HV0.2) and wear resistance when the rare-earth oxide content reached 0.75% CeO2 and 1.50% Y2O3. Additionally, the minimum corrosion rates of the coating were measured at 0.002770 mm/a and 0.0022548 mm/a at 1.5% CeO2 and 1.5 Y2O3 doping, with noble Ecorr values ranging from -0.12549 V to -0.49924 V and lower Icorr values ranging from 2.3550?10-7 A?cm2 to 1.9170?10-7 A?cm2. Furthermore, the wear resistance of the cladding layer was significantly higher than that of the substrate. Both the cladding layer and the substrate exhibited a mixed-wear mode, and they exhibit adhesive wear in wet friction environments.
Recovery of pure lithium phosphate from sulfuric acid leaching solutions of spent LiFePO4 batteries by solvent extraction and chemical precipitation
Authors: Chen J. , Tran T. , Lee M.
Published: June 2024

With the increasing use of electric vehicles, the demand for lithium iron phosphate batteries (LiFePO4) has risen sharply. Therefore, the recycling of metals from these batteries at the end of their life is necessary. In this study, a hydrometallurgical process for the recovery of lithium phosphate from spent LiFePO4 batteries was developed. The effects of the parameters on the recovery process, consisting of leaching, solvent extraction, and precipitation were investigated. The addition of H2O2 to the H2SO4 solution was ineffective for the selective leaching of Li(I) over iron. The results showed that Li(I) and iron were completely dissolved by 1.5 mol/L H2SO4, 100 g/L pulp density at 25 ?C for 60 min at 300 rpm. After oxidation of Fe(II) in the leaching solution by addition of H2O2, Fe(III) was completely separated from the solution by five steps of cross-flow extraction with 1.0 mol/L D2EHPA at room temperature. The loaded Fe(III) was successfully separated by four steps of cross-current stripping with 50% (v/v) aqua regia solution. Finally, most Li(I) was recovered by precipitation of lithium phosphate from the iron-free raffinate by maintaining the pH of the solution at 11 and the temperature at 95 ?C for 30 min. The optimum conditions for the complete dissolution of LiFePO4 batteries by sulfuric acid solution and for the separation of iron and lithium ions from the leaching solutions were determined. A hydrometallurgical process was proposed for the recovery of pure lithium phosphate from spent LiFePO4 batteries.
Aluminizing as a method of improvement of Mar-M247 alloy lifetime
Authors: Zagula-Yavorska M.
Published: June 2024

Environmentally friendly high temperature high-activity (HTHA) and high temperature low- activity (HTLA) CVD aluminizing processes were realized on the Mar-M247 heat resistant superalloy substrate that is widely used in the hot section of aircraft engines. Additionally, commercial aluminide coatings deposited in the above-the-pack aluminiznig process were analyzed. The aluminizing of the Mar-M247 superalloy by the HTHA, HTLA and above-the-pack processes led to formation of two layers of the coatings. The outer layer of the coatings formed by the above-the-pack process consisted of the ?-NiAl phase with precipitates, while the outer layer of coatings formed by the HTHA and HTLA processes consisted of the pure ?-NiAl phase. Aluminizing successfully improved the lifetime of Mar-M247 superalloy. Despite the fact that the coatings formed by the above-the-pack process are thicker and have a higher aluminium concentration than the coatings formed by the HTLA aluminizing and process, the lifetime of the coated superalloy was lower. Moreover the oxidation resistance of the coated superalloy in the HTLA aluminizing process was better than that of the coating in the HTHA aluminizing process. The removal of impurities in the HTLA aluminizing process ensured a ?pure? outer layer of the coatings. Clean aluminide coatings may create a purer alumina oxide and may prolong its lifetime.

OBJECTIVE

To characterize distinct islet autoantibody profiles preceding stage 3 type 1 diabetes

RESEARCH DESIGN AND METHODS

The T1DI (Type 1 Diabetes Intelligence) study combined data from 1,845 genetically susceptible prospectively observed children who were positive for at least one islet autoantibody: insulin autoantibody (IAA), GAD antibody (GADA), or islet antigen 2 antibody (IA-2A). Using a novel similarity algorithm that considers an individual’s temporal autoantibody profile, age at autoantibody appearance, and variation in the positivity of autoantibody types, we performed an unsupervised hierarchical clustering analysis. Progression rates to diabetes were analyzed via survival analysis.

RESULTS

We identified five main clusters of individuals with distinct autoantibody profiles characterized by seroconversion age and sequence of appearance of the three autoantibodies. The highest 5-year risk from first positive autoantibody to type 1 diabetes (69.9%; 95% CI 60.0–79.2) was observed in children who first developed IAA in early life (median age 1.6 years) followed by GADA (1.9 years) and then IA-2A (2.1 years). Their 10-year risk was 89.9% (95% CI 81.9–95.4). A high 5-year risk was also found in children with persistent IAA and GADA (39.1%) and children with persistent GADA and IA-2A (30.9%). A lower 5-year risk (10.5%) was observed in children with a late appearance of persistent GADA (6.1 years). The lowest 5-year diabetes risk (1.6%) was associated with positivity for a single, often reverting, autoantibody.

CONCLUSIONS

The novel clustering algorithm identified children with distinct islet autoantibody profiles and progression rates to diabetes. These results are useful for prediction, selection of individuals for prevention trials, and studies investigating various pathways to type 1 diabetes.

Authors: Ratusznik Natalia , Edslev Sofie Marie , Stegger Marc , Söderquist Bo
Published: June 2024

Patients with atopic dermatitis (AD) are more likely than healthy individuals to harbour Staphylococcus aureus on their skin. Superantigens (SAgs) produced by specific S. aureus strains may contribute to AD-associated skin inflammation. The present study compared the prevalence and types of SAg-encoding genes between S. aureus isolated from patients with AD and from  controls, and within the AD group between isolates from different sampling sites (lesional skin, non-lesional skin, and nares). This retrospective case-control study extracted data from 2 previous studies that examined S. aureus using whole-genome sequencing. The 138 S. aureus isolates obtained from 71 AD patients contained 349 SAg-encoding genes; 22 (6.3%) were found in isolates from nares (0.4 ± 0.6 genes per isolate), 99 (28.4%) in isolates from non-lesional skin (3.7 ± 3.9), and 228 (65.3%) in isolates from lesional skin (4.2 ± 4.5). S. aureus (n = 101) from the control group contained 594 SAg-encoding genes (5.9 ± 4.2). Of the S. aureus isolated from lesional AD skin, 69% carried at least 1 gene encoding SAg compared with 33% of AD nasal isolates. SAg could be a factor in the pathogenesis of a subset of AD patients.

Exploring Digital Biomarkers for Depression Using Mobile Technology
Authors: Zhang Yuezhou , Folarin Amos , Dobson Richard
Published: June 2024

Introduction & BackgroundWith the advent of ubiquitous sensors and mobile technologies, wearables and smartphones offer a cost-effective means for monitoring mental health conditions, particularly depression. These devices enable the continuous collection of behavioral data, providing novel insights into the daily manifestations of depressive symptoms.
Objectives & ApproachThe present study summarizes findings from our five recent investigations that explored the relationships between depression severity and digital biomarkers captured by wearables and smartphones. These studies analyzed data from RADAR-MDD, a multinational mobile health program, involving 623 participants and tracked for up to two years. Participants' depression severity was measured biweekly using the PHQ-8 questionnaire conducted via smartphones. Concurrently, participants’ Fitbit and smartphone data were also collected. Given the longitudinal nature and repeated measurements for each participant, multilevel modeling techniques were employed to analyze the data.
Relevance to Digital FootprintsOur approach involved extracting features from passive data that reflect various aspects of daily behavior—such as sleep quality, social interaction, physical activity, and walking patterns—akin to digital footprints.
ResultsWe found several significant links between depression severity and various behavioral biomarkers: elevated depression levels were associated with diminished sleep quality (assessed through Fitbit metrics), reduced sociability (approximated by Bluetooth), decreased levels of physical activity (quantified by step counts and GPS data), a slower cadence of daily walking (captured by smartphone accelerometers), and disturbances in circadian rhythms (analyzed across various data streams).
Conclusions & ImplicationsLeveraging digital biomarkers for assessing and continuously monitoring depression introduces a new paradigm in early detection and development of customized intervention strategies. Findings from these studies not only enhance our comprehension of depression in real-world settings but also underscore the potential of mobile technologies in the prevention and management of mental health issues.

Authors: Liodaki Niki , Karalis Thanassis
Published: June 2024

Surveys that examine the perceptions of employees regarding lifelong learning in Greece reveal that employees have a positive attitude towards education and also indicate that about 70% of the working population showed intention to participate in some form of continuing education. However, the participation rates of Greek employees in educational programs are below the European average. At this point, it is worth noting that little is known regarding the barriers that prevent them from participating. In this light, the present study is the first attempt to investigate both individual barriers and barrier categories of employees’ participation in Greece. Survey data were collected using a questionnaire. The results of the present study revealed four categories of barriers. Of these, situational barriers gathered the highest average, followed by institutional: state/institute barriers and, institutional: working environment and, to a lesser extent, dispositional barriers. In particular, the three main barriers faced by employees were the “lack of time due to work obligations”, the “participation cost”, and the “lack of time due to taking care of children.” In addition, the categories of barriers were found to be related to three of the four demographic variables examined: gender, employment status, and occupation, which were independent of age.

Educators need insights into how various learning styles can influence learners' performance in assessments. Exploring the impact of different learning styles on EFL learners' TOEFL reading achievement is a multidimensional endeavor with implications for educators, learners, and the broader society. This study aims to investigate the extent to which vocational diploma EFL learners acquired English based on their preferred learning styles. The ex-post facto design was used for this study. As many as 37 participants were selected purposely from all majoring fourth semester students at an EFL vocational diploma college. A questionnaire was used to divide the participants into three groups depending on their preferred learning styles: visual, auditory, and kinesthetic. A TOEFL reading test was employed to measure the participants’ English proficiency. The average scores for each learning style group were calculated and revealed that visual learners had an average TOEFL reading score of M=43.22, kinesthetic learners had an average TOEFL reading score of M=38.70, and auditory learners had an M=35.00. To statistically compare these averages, one-way analysis of variance (ANOVA) was used. The ANOVA results showed a non-significant finding with df=2, F=1.102 and P=0.344. The findings revealed that the TOEFL reading comprehension scores of students with different learning styles did not differ significantly. This study contributes to the ongoing discourse surrounding individualized learning experiences and standardized language assessments. As the field of language education continues to evolve, further research will be pivotal in refining pedagogical practices to better meet the diverse needs of learners striving to excel in their language proficiency endeavors.

In today's digital era, students need digital literacy skills to critically navigate, evaluate, and analyze a large amount of online information. Digital literacy uses digital technology to obtain, evaluate, create, and communicate information in various contexts. This research aimed to investigate the impact of CDA in improving students' digital literacy, explore the role of CDA in enhancing students' digital literacy, and identify the lecturer's strategy in using CDA for enhancing students' digital literacy. This current study used classroom action research as a research design which consisted of two cycles. The participants in this research were college students at STIE Gentiaras Lampung. The instruments of this research consisted of tests and non-test. Quantitative data was taken from students' digital literacy tests, and qualitative data were taken from observation and interviews. The findings show that CDA can improve students' digital literacy. Moreover, there were five roles of CDA in enhancing students' digital literacy: fostering critical thinking, promoting media literacy, enhancing textual analysis, encouraging social awareness, and cultivating responsible digital citizenship. The last finding is the teacher employed three strategies to improve students' digital literacy: acquainting them with the fundamental principles of CDA, selecting diverse texts for comprehensive CDA analysis, and encouraging classroom discussions. According to the findings, policymakers can consider integrating CDA into educational curricula to enhance students' digital literacy skills.

English language textbooks play an essential role in presenting learning material and assisting students in acquiring language skills. Most Indonesian teachers heavily depend on textbooks; however, they often lack knowledge about the task types employed in textbooks. The study aims to analyze the tasks in the English textbook and the types of tasks presented in the English textbook English for Nusantara. English for Nusantara is the primary sourcebook for seventh and eighth-grade junior high school students in Kurikulum Merdeka. The analysis was conducted by utilizing Nunan's (1990) typology of tasks to determine the different categories and frequency of tasks within the textbooks. Stratified random sampling was used for this research, and tasks were taken from two different units in each textbook. The findings indicated that the textbooks comprise various types of tasks, and each of the textbooks emphasized distinct task types. The seventh-grade textbook places a greater emphasis on cognitive tasks, whereas the eighth-grade textbook places a greater emphasis on interpersonal tasks. Nonetheless, the task distribution is unbalanced, and certain categories of tasks remain unaddressed in both textbooks; specifically, creative and affective tasks are absent.
‘That baby is a Fenian’: Gothic Violence, Gender, and Nationality in Two Plays of David Ireland
Authors: Devereux Anna
Published: June 2024

'The oldest and strongest kind of fear is fear of the unknown’, claimed author H.P. Lovecraft. The relationship between fear, knowledge, and paranoia is a common theme in many Gothic texts, such as Bram Stoker’s Dracula and Charlotte Brontë’s Jane Eyre, in which fear is generated by information withheld or obscured. Although ‘Gothic’ is a term usually reserved for literary fiction, in this paper I ask: can an understanding of Irish gender and nationalist conflict be found in the Gothic? Contemporary playwright David Ireland uses Gothic techniques to address community violence, national identity and gender. In their depictions of violent paranoia, sinister disguises, and psychological unravellings, David Ireland’s plays depict social unrest linked to conflict on the island of Ireland. In this paper I will take his plays Cyprus Avenue (2016) and Ulster American (2018) as key texts through which to view Gothic presence in modern Irish culture, analysing the ways they address conflict regarding gender and national identity. This analysis will be guided by the conceptual framework of feminist and queer theory, in particular Jack Halberstam's Skin Shows (1995) and Barbara Creed’s The Monstrous-Feminine (1993). I will make the case that in these plays we can view fear of the unknown as a defining feature of conflict in modern Ireland.

Social network analysis is a rapidly evolving research area having several real-life application areas, e.g. digital marketing, epidemiology, spread of misinformation. Influence maximization aims to select a subset of nodes in such manner that the information propagated over the network is maximized. Competitive influence maximization, which describes the phenomena of multiple actors competing for resources within the same infrastructure, can be solved with a greedy approach selecting the seed nodes utilizing the influence strength between nodes. Recently, deep reinforcement learning methods were applied for estimating the influence strength. We train a controller with reinforcement learning for selecting a node list of given length as the initial seed set for the information spread. Our experiments show that deep Q-learning methods are suitable to analyze the competitive influence maximization on trust and distrust based social networks.
Keywords: influence maximization, reinforcement learning, Q-learning.
