Authors: Khorshid Alireza , González Daniel , Zhang Jian-Zhi
Published: July 2024

Objective: This study compares and evaluates hemoglobin and erythropoietin levels in patients with polycythemia vera and secondary polycythemia.
Design: This was aretrospective cross-sectional study evaluating the serum erythropoietin and Hb levels in patients with polycythemia vera and secondary polycythemia.
Setting: This study was performed simultaneously in Texas state of the U.S. and Fars Province in Iran.
Participants: Hemoglobin, hematocrit and erythropoietin test results were collected from patients aged 19 to 75 years who were diagnosed with polycythemia vera and secondary polycythemia.
Intervention: To evaluate the effect of a JAK2 mutation on erythropoietin (EPO) and hemoglobin levels in polycythemia patients in Texas, the U.S., and Fars Province, Iran.
Main Outcome Measures: Patients with polycythemia vera had decreased erythropoietin and increased hemoglobin levels compared with patients with secondary polycythemia.
Results: The present study showed (P=0.5) that, compared with those in patients with secondary polycythemia, the serum hemoglobin and erythropoietin levels in patients with polycythemia vera were not significantly different.
Conclusion: Low erythropoietin levels may not be helpful in differentiating polycythemia vera from secondary polycythemia. According to WHO diagnostic guidelines, the best test for the diagnosis of polycythemia vera is the JAK molecular genetic test.

Published: July 2024

The combination of isothermal amplification and CRISPR-Cas12a system is a valuable tool for detecting nucleic acids, especially in emergency situations or disease outbreaks. However, achieving compatibility between these technologies has been a challenge because the CRISPR reaction eagerly cleaves nucleic acid amplification template before isothermal amplification is complete. This study presents a method called CIRCLE, which effectively addresses the compatibility issue by dividing crRNA into a universal circular DR region with a PC linker and a replaceable spacer region. Different targets could be detected in a single separate way by changing the spacer region. Furthermore, DNA modifications were firstly introduced into circular crRNA to regulate CRISPR-Cas12a system using base excision repair (BER) enzymes. The programmable strategy showed potential to detect different BER enzymes and regulate Cas12a gene-editing activity by adjusting BER enzyme levels. In the future, it holds promise for selectively editing genes in cells that express high levels of specific BER enzymes, such as UDG, in colon cancer cells. The findings of this study contribute to advancing the field of nucleic acid detection and gene editing. The CIRCLE method is a programmable and resource efficient approach for medical diagnostic applications, making it particularly valuable in future clinical settings.
Assessing the Impact of Price-Matching Guarantees and Price Fluctuations on Consumer Feedback: Insights from the Online Consumer Electronics Market
Authors: Robbiano Simone , Cerruti Gianluca
Published: July 2024

Our study investigates the impact of price matching guarantees (PMGs) on consumer behavior in online retail markets. Leveraging a Difference-in-Differences (DiD) approach, we analyze product ratings in response to price changes during PMG policy periods. Results show that PMGs alone have no significant effect on ratings, but price increases during PMG periods lead to lower ratings. Furthermore, the effect strengthens over time, particularly for cheaper and less visible products. These findings suggest that PMGs may serve as effective market signals of pricing strategy, especially for items where price sensitivity is higher or visibility is lower. This underscores the importance of signaling mechanisms in influencing consumer perceptions and responses in online retail settings. From an antitrust perspective, our results highlight the potential for PMGs to influence competition dynamics and consumer welfare. Policymakers may need to consider regulations ensuring pricing transparency and consumer protection in online markets, balancing the benefits of market signaling with the risks of anti-competitive behavior and consumer harm. Overall, our study contributes to the understanding of pricing strategies and consumer behavior in digital markets, with implications for both industry practices and regulatory interventions.

Authors: Zhadan Alexander V. ,   Vladivostok Branch of the Far Eastern Law Institute of the Ministry of Internal Affairs of Russia
Published: July 2024

The problem of providing employees with food was one of the most difficult and urgent for the leadership of the NKVD during the Great Patriotic War. The efficiency of labor collectives, the moral and psychological state of the staff directly depended on the solution of this issue. In this publication, based on documentary sources, a significant part of which is being introduced into scientific circulation for the first time, the goal was to analyze and summarize the historical experience of the activities of the territorial bodies of the NKVD of the Far East in solving the issue of food supply of personnel. The research used the principles of historicism, objectivity and consistency, as well as methods of social history. The conducted research showed that the wartime had a negative impact on the financial situation of the NKVD personnel. The problem of meeting the basic living needs of employees, in particular the provision of food, has become particularly acute. This situation reduced the motivation of labor collectives, provoked the commission of disciplinary offenses and crimes caused by the desire of employees to improve the financial situation of their families. The main ways to improve the food supply system for employees of the territorial bodies of the NKVD of the Far East during the Great Patriotic War were: the expansion of the practice of self-procurement and decentralized procurement; the introduction of a system of standardized food supply for employees; streamlining the activities of the Special Trade system; improving the efficiency of subsidiary farms; the development of individual and collective gardening. Characteristic aspects of the life of the employees were agricultural work in individual and collective gardens, in subsidiary farms. The implemented set of measures made it possible to ensure the food security of labor collectives, which should certainly be considered an important merit of the leadership and party organizations of the Far Eastern NKVD bodies. At the same time, activities related to self-sufficiency led to a significant diversion of personnel resources from solving the main service and operational tasks, which negatively affected the effectiveness of law enforcement work.

On ships, practically all types of induction machine loads are present, among which those with fan and gravitational characteristics are the most common. This paper addresses the speed–time curve dependency on the direct start of an induction machine under gravitational load. The characteristic of speed–time, ω = f (t), is described through two analytical expressions. The first expression is derived using the formula for torque based on Thévenin’s equivalent circuit, while the second expression is derived from Kloss’s formula for torque. The mathematical model has been tested through simulation and experimental validation on an induction machine in laboratory conditions. Also, the paper includes a realised MATLAB program for determining the mentioned characteristics. The results show the high precision and practical applicability of the proposed analytical expressions in different working conditions.
Importance of the X-ray edge singularity for the detection of relic neutrinos in the PTOLEMY project
Authors: Tan Zhiyang , Cheianov Vadim
Published: July 2024

Direct detection of relic neutrinos in a beta-decay experiment is an ambitious goal that has long been beyond the reach of available technology. One of the most challenging practical difficulties for such an experiment is managing a large amount of radioactive material without compromising the energy resolution required to distinguish useful events from the substantial beta-decay background. The PTOLEMY project offers an innovative solution to this problem by depositing radioactive material on graphene. While this approach is expected to address the main challenge, it introduces new issues due to the proximity of the beta decayers to a solid-state system. In this work, we focus on the effect of the shakeup of the graphene electron system caused by a beta-decay event. We calculate the distortion of the relic neutrino peaks resulting from this shakeup, analyze the impact of the distortion on the visibility of neutrino capture events, and discuss potential technological solutions to enhance the visibility of these events.

Published: July 2024

This study aims to examine the internal determinants of financial performance of food supermarkets listed on the South African stock exchange. Food supermarkets play an integral role in socio-economic development of the country. The study employed an econometric approach utilizing fixed effect panel data. Drawing information from audited financial statements, data were gathered from four major listed food supermarkets in South Africa covering the period from 1994 to 2022, resulting in a total of 116 observations over 29 years. The robust longitudinal statistics obtained from balanced data revealed a significant positive correlation between equity financing, size of corporate governance, and current debt with financial performance, as measured by sales revenue at 0.0000, 0.054, and 0.000 significance levels, respectively. The findings indicate that as these variables increase, the financial performance of the studied food supermarkets (Shoprite, Woolworths, Spar, and Pick n Pay) also increases. Conversely, a negative and significant relationship is noted between company age, current assets, and financial performance at significance levels of 0.007 and 0.002, respectively. This suggests that as these variables increase, financial performance will decrease. As per the research findings, it is imperative for supermarkets to uphold a well-rounded blend of equity and debt and adopt inventive business approaches as they mature to improve financial outcomes. Therefore, the study proposes a framework focusing on internal factors that impact the financial performance of listed food supermarkets in South Africa.
Assessing social capital and its impact on economic performance: A comparative study of members and non-members of farmer producer companies in India
Authors: Malik Sushant , Kajale Dilip
Published: July 2024

Farmer producer companies (FPCs), modern farmer collectives registered under India’s Companies Act, play a crucial role in providing core services like input supply, marketing, technical, and financial support, as well as auxiliary services such as social capital and consultancy, which are linked to higher economic performance and innovation. The study analyzes the levels of social capital among members and non-members of FPCs and their relationship to the economic performance of their members. The data on social capital were collected from 20 FPCs (292 members and 77 non-members) from Maharashtra state of India. Unpaired student T-tests and Mann-Whitney tests were performed to compare the levels of social capital among the members and non-members. OLS regression was performed to understand the difference in social capital and its effect on economic performance. The results reveal that all the indicators of social capital were significantly higher for the members (Mean = 4.27) than for non-members (Mean = 3.14). The social capital indicators related to membership and participation in groups (p-value < 0.10) and the sharing of production and other information (p-value < 0.01) positively affected economic performance. Higher levels of education (p-value < 0.05) and frequent contact with members (p-value < 0.01) positively affected, whereas higher landholding (p-value < 0.10) and years of membership (p-value < 0.01) negatively affected the economic performance of members. As the Indian government plans to add 10,000 FPCs in the next three years, the strategy to increase the social capital of FPCs may enhance the overall resilience and sustainability of rural economies.

Published: July 2024

This study used vibration testing signals of soil samples under external loading to identify modal parameters (including natural frequencies and damping ratios) with different compaction degrees. Based on these parameters, a novel approach was proposed for reliable roadbed vibration compaction control and compaction process optimization. The experimental section utilized six soil samples with varying compaction degrees as experimental subjects, using the hammering method as the excitation mode. Subsequently, the frequency response function and modal parameters of the sample system were obtained through the acquisition, analysis, and parameter identification of samples’ acceleration signals. Firstly, samples with compaction degrees ranging from 88 % to 97 % primarily exhibited three modes, with the second modal frequency response displaying the weakest amplitude, and the fundamental mode being the dominant one. Additionally, parameter identification results revealed that the fundamental modal frequency exhibited a significant negative exponential growth with increasing compaction degree, while the second and third modal frequencies showed significant linear growth. Furthermore, the average damping ratio also demonstrated a tendency toward linear change with increasing compaction degree. Finally, the feasibility of modal parameters being actively used in practical engineering is discussed. Consequently, this study aimed to propose an indicator system for accurately assessing the bearing level of compacted soils from a modal dynamics perspective and to integrate modal dynamic indicators with density-class indicators into further optimization design work on road compaction processes.

Impact of flexible vegetation on hydraulic characteristics in compound channels with converging floodplains
Authors: Awasthi Noopur , Kumar Munendra , Raj Ritu
Published: July 2024

Floodplains in natural rivers are curved and narrow, rather than following a straight path and the presence of vegetation and varying depth of flow affects the flow parameters of the channels. The purpose of this study is to investigate the effects of the convergence of the channel and relative depth of flow on the depth-averaged velocity (DAV) and boundary shear stress (BSS) of a converging compound channel. The effect of vegetation on DAV and BSS was also deliberated. To examine the effect of vegetation, synthetic grass 8 cm in height was used as a flexible vegetation to depict the natural conditions of the rivers. The DAV was calculated using an acoustic Doppler velocimeter (ADV) and the measurement of BSS was done using the Preston tube technique. After analysing the data, it was revealed that as the convergence of floodplains increases, maximum DAV increases. The presence of vegetation reduces the velocity specifically at lower flow depths. BSS increases with the convergence as well as vegetation. This research provides valuable data and results which will be helpful in better flood management, river restoration, and designing effective hydraulic structures.

Authors: Jose Paulraj Adwin , Sankarganesh Murugesan , Raja Jeyaraj Dhaveethu , Rajesh Jegathalaprathapan
Published: July 2024

This chapter presents research on using novel dye-degrading processes in the
chemical process industries to prevent the increasing water demand caused by the
overuse of water in businesses near farmland. This chapter also describes the dye
degradation processes used to treat industrial effluents contaminated with dyes and the
associated chemical reactions, benefits, and drawbacks. Commonly employed chemical
techniques for treating industrial effluents contaminated with dyes demand more costly
chemicals and reagents for dye degradation. Solid precipitates or emulsions are created
when the additional chemicals interact or react with the contaminants in the industrial
effluents that are contaminated with dye. These products could harm our ecological
creatures in a variety of ways. Physiological techniques like membrane filtration, nanofiltration, ultrafiltration, and microfiltration have their membrane pores closed by
different pollutants, shortening their lifespan. The primary focus of this chapter is on
the dye degradation characteristics of graphene oxide nanocomposite materials that
have been mixed or doped with different metal oxides and metal nanoparticles. These
days, there is increased interest in carbon-based compounds such as graphene and
graphene oxides due to their potential environmental benefits when used in the oil and
organic gas industry to purify water. The water purification activity of graphene oxide
filters is further increased when combined with photochemical active metal oxide.
Another benefit is that they don't require extra chemicals or reagents, which also
indirectly control other pollutants, and they use solar energy rather than electrical
energy. These graphene oxide nanocomposites are unique because they can regenerate
without chemicals once they run out of resources. Its physical and chemical
characteristics don't change over many cycles.
Synthesis and Characterization of CdS and ZnS Nanostructured Thin Films for Opto-electronic Energy Applications
Authors: Bairy Raghavendra , H. Vijeth , K. Rajesh , Deshmukh Rohan S.
Published: July 2024

Since their early discovery, thin films have quickly found industrial uses, including
decorative, optical, and energy storage applications. The range of applications for thin film
technology has expanded to the point where nearly every industrial sector now uses it to impart
specific physical and chemical properties to the surface of bulk materials. The ability to
customize film properties by varying the microstructure through the deposition parameters used
in a particular deposition technique has recently allowed them to advance from the most basic
applications, like protective coatings against wear and corrosion, to the most technologically
advanced ones, like microelectronics and biomedicine. Despite such remarkable advancements,
the relationship between all phases of the fabrication of metal sulphide thin films such as CdS
and ZnS specifically deposition parameters – morphology and characteristics, is not entirely
precise. In summary, the characterization of thin films involved several techniques, including
X-ray diffraction, UV-Vis spectrophotometry, scanning electron microscopy, energydispersive X-ray diffraction, and transmission electron microscopy. The investigation of
nonlinear optical (NLO) parameters was carried out through open aperture (OA) and closed
aperture (CA) Z-scan measurements, employing a diode-pumped solid-state continuous-wave
laser at 532 nm excitation. The NLO parameters, namely the nonlinear absorption coefficient
(β), nonlinear refractive index (n2), and third-order NLO susceptibility (χ(3)) exhibited an
increasing trend with higher doping concentrations. These promising outcomes regarding the
NLO parameters in nanostructured CdS and ZnS thin films with increasing doping
concentrations suggest that these processed films hold significant potential for applications in
opto-electronic energy-related technologies.

Dengan menggunakan konservasi tata guna lahan baru diperoleh penurunan laju erosi pada DAS Bedadung yaitu dengan Indeks Bahaya Erosi (IBE) kriteria rendah seluas 3275,53 ha dan sedang seluas 67667,87 ha. Hasil tersebut menunjukkan skenario tata guna lahan yang baru dapat mengurangi laju erosi pada DAS Bedadung.
Land use change in the Bedadung watershed has caused the area to experience frequent floods due to increased erosion and sedimentation. To reduce the existing problems, land conservation efforts are needed by using new land use (scenarios). This study used the ArcSWAT model to calculate the potential erosion and sedimentation to map the distribution of the Erosion Hazard Index (EHI) in the Bedadung watershed. Based on the simulation results in the existing condition, the average erosion rate was 31.29 tons/ha/year and sedimentation was 23.33 tons/ha/year. The results of the Erosion Hazard Index (EHI) analysis obtained 3 criteria, low with an area of 2038.63 ha (2.87% of the land area), medium with an area of 49958.86 ha (70.42% of the land area), and high with an area of 18945.91 ha (26.71% of the land area). Using the new land use conservation, the erosion rate in the Bedadung watershed was reduced, with the Index of Erosion Hazard (EHI) of low criteria covering an area of 3275.53 ha and medium covering an area of 67667.87 ha. These results show that the new land use scenario can reduce the erosion rate in the Bedadung watershed.

Authors: Leung Nicholas , Waki Kayo , Nozoe Satoshi , Enomoto Shunpei , Saito Ryo , Hamagami Sakurako , Yamauchi Toshimasa , Nangaku Masaomi , Ohe Kazuhiko , Onishi Yukiko
Published: July 2024

Background

Lifestyle modifications are a key part of type 2 diabetes mellitus treatment. Many patients find long-term self-management difficult, and mobile apps could be a solution. In 2010, in the United States, a mobile app was approved as an official medical device. Similar apps have entered the Japanese market but are yet to be classified as medical devices.

Objective

The objective of this study was to determine the efficacy of Save Medical Corporation (SMC)–01, a mobile app for the support of lifestyle modifications among Japanese patients with type 2 diabetes mellitus.

Methods

This was a 24-week multi-institutional, prospective randomized controlled trial. The intervention group received SMC-01, an app with functions allowing patients to record data and receive personalized feedback to encourage a healthier lifestyle. The control group used paper journals for diabetes self-management. The primary outcome was the between-group difference in change in hemoglobin A1c from baseline to week 12.

Results

The change in hemoglobin A1c from baseline to week 12 was –0.05% (95% CI –0.14% to 0.04%) in the intervention group and 0.06% (95% CI –0.04% to 0.15%) in the control group. The between-group difference in change was –0.11% (95% CI –0.24% to 0.03%; P=.11).

Conclusions

There was no statistically significant change in glycemic control. The lack of change could be due to SMC-01 insufficiently inducing behavior change, absence of screening for patients who have high intention to change their lifestyle, low effective usage of SMC-01 due to design issues, or problems with the SMC-01 intervention. Future efforts should focus on these issues in the early phase of developing interventions.

Published: July 2024

Background

Out-of-hospital cardiac arrest (OHCA) is a leading cause of mortality in the developed world. Timely detection of cardiac arrest and prompt activation of emergency medical services (EMS) are essential, yet challenging. Automated cardiac arrest detection using sensor signals from smartwatches has the potential to shorten the interval between cardiac arrest and activation of EMS, thereby increasing the likelihood of survival.

Objective

This cross-sectional survey study aims to investigate users’ perspectives on aspects of continuous monitoring such as privacy and data protection, as well as other implications, and to collect insights into their attitudes toward the technology.

Methods

We conducted a cross-sectional web-based survey in the Netherlands among 2 groups of potential users of automated cardiac arrest technology: consumers who already own a smartwatch and patients at risk of cardiac arrest. Surveys primarily consisted of closed-ended questions with some additional open-ended questions to provide supplementary insight. The quantitative data were analyzed descriptively, and a content analysis of the open-ended questions was conducted.

Results

In the consumer group (n=1005), 90.2% (n=906; 95% CI 88.1%-91.9%) of participants expressed an interest in the technology, and 89% (n=1196; 95% CI 87.3%-90.7%) of the patient group (n=1344) showed interest. More than 75% (consumer group: n= 756; patient group: n=1004) of the participants in both groups indicated they were willing to use the technology. The main concerns raised by participants regarding the technology included privacy, data protection, reliability, and accessibility.

Conclusions

The vast majority of potential users expressed a strong interest in and positive attitude toward automated cardiac arrest detection using smartwatch technology. However, a number of concerns were identified, which should be addressed in the development and implementation process to optimize acceptance and effectiveness of the technology.

In the 21st century, students must have high knowledge and thinking skills which can be achieved through learning activities. This study aimed to develop a Project-Based Module (PBM) on the topic of determination, differentiation, and organogenesis that is feasible and effective in improving students' cognitive learning outcomes (CLO), critical thinking (CTS), and problem-solving skills (PSS). The module used the 4D developmental model consisting of define, design, develop, and disseminate, which then underwent validation and student response for its feasibility in terms of material adequacy, learning process, and layout design. The module was also tested for its effectiveness in improving CLO, CTS, and PSS. The result showed that the module was tested valid and categorized as "very worthy" as 91.6 % by material expert, learning expert, and layout expert. Students gave excellent responses to the module as 87.77 % with a very worthy category. Moreover, the independent t-test results show a significant difference in CLO (P = 0.00), CTS (P = 0.00), and PSS (P= 0.00) between the control and experimental posttest results. Thus, the project-based module improves student’s CLO, CTS, and PSS in the animal development course. Further research needs to be extended for wider-scale trials to obtain maximum results.

National insight is an important concept that should be internalized by the younger generation. The understanding of national insight among students, as the younger generation, is still categorized as insufficient, so efforts are needed to strengthen national insight through the Compulsory Curriculum Subjects of Indonesian Language. This research aims to reveal the ideology of national insight within the teaching materials of Compulsory Curriculum Subjects of Indonesian Language from Norman Fairclough's perspective in 2013 with the theory of critical discourse analysis. This research used a qualitative approach. The research data were obtained from texts in the teaching materials of Compulsory Curriculum Subjects of Indonesian Language. Texts containing the concept of national insight were analyzed using Norman Fairclough's 2013 model of critical discourse analysis. The research data obtained were analyzed through the stages of reduction, presentation and verification. The data validation in this research was conducted using triangulation techniques. The results showed that in terms of the text aspect, both texts represent the ideology of love for the nation and homeland, as well as the aspiration for a just and prosperous society, through a text theme focusing on the obligation to pay taxes. In terms of discourse practice, the role of language in both texts serves as a tool for promoting an ideology by the involved groups. Furthermore, in terms of social-cultural practice, both texts emphasize socio-economic aspects. In conclusion, the teaching materials of Compulsory Curriculum Subjects of Indonesian Language represent several ideologies of national insight through texts that are presented as a means of spreading ideology by considering social and economic aspects. The results of this research have implications for national insight education for students in higher education through texts containing national insight contained in teaching material of Compulsory Curriculum Subjects of Indonesian Language.

Creating instructional materials is an essential responsibility for educators during the process of teaching and learning. Prospective instructors can learn skills in compiling instructional materials during their undergraduate studies. This technique entails the utilization of students' writing proficiency and autonomous capabilities in developing inventive instructional resources. The CANVA program is a useful tool for creating educational materials. Presently, higher education can be pursued through both traditional in-person instruction and online platforms. This project employs the Online Self-Regulated Learning (SRL) technique and utilizes e-learning tools to generate Indonesian language teaching materials for Foreign Speakers (BIPA). The research is to examine the influence of Online Self-Regulated Learning on the proficiency in creating BIPA teaching materials using the Canva application among aspiring Indonesian language instructors at Padang State University. This research employed experimental methodologies and quasi-experimental designs, specifically utilizing a posttest only control design. The group under study comprises students enrolled in the 2020 cohort of the PBSI Study Program. Purposive sampling strategies were employed to choose two classes as samples for this investigation. The research instrument is an assessment tool. The data analysis process included conducting normality and homogeneity tests on the data, followed by performing the Independent Sample T Test. The results indicated that the data did not follow a normal distribution, thus it was analyzed using Mann U Whitney non-parametric statistics. The test results indicate a notable disparity in the mean learning outcomes between students who employ the Online Self-Regulated Learning technique to create BIPA teaching materials using the Canva application, and students who utilize the assignment method.
