The innovation and local culture in the production of specialty coffee in Short Food Supply Chains and their impacts on environmental sustainability
Authors: Campos Amanda dos Santos Negreti , Pigatto Giuliana Aparecida Santini , Baptista Renato Dias , Queiroz Timóteo Ramos
Published: August 2024

Coffee, popularly known as commodities, stimulates the farmer´s interest to innovate and to add value in products aiming for lucrative. One way to add value is through Short Food Supply Chains (SFSC), innovating and valorizing product processes, with basis on local culture. The main aim of this article was to analyze innovations developed by specialty coffee producers from Garça, Brazil, as they were introduced into SFSC and their impacts on environmentally sustainable production. This is a qualitative-quantitative research, with multiple case studies. Data was collected through semi-structured interview observation and documents, and analysis was carried out using Fisher's Exact Test. The main innovations verified for insertion in SFSC are the marketing skills, technical processes used in the harvesting, and machinery acquisitions for processing and packaging products without compromising the quality of the beverage. Although producers made a strenuous effort to promote the environmental sustainability, the statistical test has confirmed that there was no association between innovations and environmental sustainability. As practical implications, this paper seeks to contribute to farmers who want to change their production by selling specialty coffees through SFSC, demonstrating the innovations and their impacts on environmental sustainability, as well as public policymakers who wish to contribute to these farmers by promoting events that generate knowledge about innovations and sustainable environmental development.

Suspended Spaces of Global Việt Nam: KT Food Stories and Gastro Cartographies of the Inscrutable
Authors: Trần Ann Thủy-Ling
Published: August 2024

Abstract: Vietnamese refugee cultural archives reveal indifference to prevalent linguistic racial homogenization using monolingual Vietnamese in digital space. By analyzing the food vlog KT Food Stories as a case study, this article demonstrates that the YouTube food channel is not unlike some restaurants or shopping centers in the physical Little Saigons across the globe in its use of nontranslation. But when English-language dominance becomes peripheralized within the suspended diasporic space of Vietnamese food vlogging, the problem of linguistic inscrutability–particularly as a basis for ridicule in dominant American popular culture–becomes reclaimed through indifference, and Vietnameseness has the potential to expand globally through intimate gastro cartographies of refuge.
The Tales of Two Peninsulas: Remaking National Myth and Remapping the US Military Base Network in Fox Gir l (2002) and Soucouyant (2007)
Authors: Chung Bonnie Yonbom
Published: August 2024

Abstract: This essay juxtaposes the US military bases located at the opposite ends of the Pacific, by reading together two fictional accounts of military prostitution—one set in Busan, a port city south of the Korean Peninsula and the other in Chaguaramas of Trinidad. Both Nora Okja Keller's Fox Girl (2002) and David Chariandy's Soucouyant (2007) turn to traditional children's folktales in recounting the history of military prostitution that is carefully carved out from each peninsula's postwar nation-building discourse. By recentering the transgressive movements of the folk figures who are prominent in the East Asian and Afro-Caribbean imaginary, the novels reimagine the geographic landscapes of each peninsula and spotlight the alternative routes of resistance in the oceanic and atmospheric. Their remaking of the vernacular tales of the soucouyant and nine-tailed fox, gumiho , challenges the discursive legacies of the US "military colony" that silence the histories of military prostitution and interrogates the developmentalist narratives underpinning the national myths.
Optimal spectral combination of spectrally combined laser beams in the turbulent atmosphere
Authors: Zhang Zhixiang , Wang Tao , Chang Hao , Ji Xiaoling
Published: August 2024

The optimal spectral combination of spectrally combined laser beams (SCLBs) propagating from the ground to orbit in the turbulent atmosphere is studied, where the atmospheric effects (e.g., turbulence, extinction and nonlinear self-focusing) are considered. The analytical propagation formulae are derived. It is found that there exists the intensity maximum at the target when the optimal central wavelength λc-opt arrives, and λc-opt is always located around 3.8µm, 8.9µm, or 10.6µm. The λc-opt depends on the spectral width, the initial beam size, and the turbulence strength. Based on λc-opt, the beam quality may be further improved by the method of removing sub-beams with low atmospheric transmittance. However, this method is invalid when the self-focusing is strong enough, while it can significantly improve the beam quality for the large initial beam size.

Authors: Fang Xiangmin , Bi Meihua , Li Zhengmin , Jin Liang , Yang Guowei , Shang Junna , Hu Miao
Published: August 2024

In this paper, we demonstrate a newly designed multi-source domain transfer learning (MST) scheme to reduce the training cost of deep neural network (DNN) based equalizer in intensity-modulation and direct-detection (IMDD) systems. Different from a common transfer learning algorithm, in this scheme, data with different channel parameters is selected and proportionally used to construct a multi-source domain dataset. This allows training the source domain in a single task while ensuring the model's generalization ability and stability. In an 80Gb/s PAM-4 IMDD short reach system, our proposed MST equalizer was proven effective. The corresponding results demonstrate that, compared to a conventional DNN equalizer, the proposed MST equalizer can achieve a bit error rate that meets the hard decision-forward error correction threshold while saving 87% of the iteration epochs and 65% of the training data.

Published: August 2024

A technique for direct laser writing of Bragg gratings in the fiber composed of high refractive index chalcogenide glass has been developed and verified. The fiber had a doped selenide glass core in an undoped sulfide glass cladding. The main features of the implemented inscription technique are solid immersion of the fiber and separate control of the focusing numerical apertures within planes perpendicular to the fiber and containing the fiber. A narrowband oscillation at 5 µm was obtained for the first time due to feedback by the Bragg grating.

Authors: Chipako Isaac , Singhal Saurabh , Hollingsworth Bruce
Published: August 2024

Despite the benefits of long-acting reversible contraceptives (LARCs), they are not being utilized in Zimbabwe as much as the short-acting reversible contraceptives (SARCs). The aim of the study was to explore factors associated with LARC usage among Zimbabwean adolescent girls and young women, using data from the 2015 Zimbabwe Demographic and Health Survey. Cross tabulations and chi-square tests were used initially to describe associations. Odd ratios were then used to measure the strength of association between LARCs usage and the independent variables using stepwise multinomial logistic regression. From the 2132 sexually active females included in the study 9.1% were LARCs users and 42% were SARCs users at the time of the survey. Secondary and primary education had increased odds of not using any method (OR: 5.032, 95% CI: 2.136–11.8512 and OR: 5.799, 95% CI: 2.327–14.453 respectively) compared to tertiary education. Women with no living children had increased odds of not using any method (OR 66.543, 95% CI: 25.784–171.7381). Being not married was associated with decreased odds of SARCs usage (OR 0.399, 95% CI: 0.285–0.558). Desire for no more children was associated with reduced odds of SARCs usage (OR: 0.448, 95% CI: 0.304–0.66). Being a member of the Apostolic Faith church was associated with increased odds of not using any method (OR 1.423517, 95% CI: 1.018–1.990309). In conclusion, acquiring a tertiary education, having children, a desire to cease bearing children altogether, being unmarried and belonging to the highest wealth class were generally associated with an increased likelihood of using LARCs. Being a member of the Apostolic Faith church was associated with a decreased likelihood of LARCs usage. Findings from the study are relevant in the Zimbabwean context and highlights the relevant factors essential to focus on, when carrying out interventions aimed at increasing LARCs uptake in the country.
Buzzfindr: Automating the detection of feeding buzzes in bat echolocation recordings
Authors: Jameson Joël W.
Published: August 2024

Quantification of bat communities and habitat heavily rely on non-invasive acoustic bat surveys the scope of which has greatly amplified with advances in remote monitoring technologies. Despite the unprecedented amount of acoustic data being collected, analysis of these data is often limited to simple species classification which provides little information on habitat function. Feeding buzzes, the rapid sequences of echolocation pulses emitted by bats during the terminal phase of prey capture, have historically been used to evaluate foraging habitat quality. Automated identification of feeding buzzes in recordings could benefit conservation by helping identify critical foraging habitat. I tested if detection of feeding buzzes in recordings could be automated with bat recordings from Ontario, Canada. Data were obtained using three different recording devices. The signal detection method involved sequentially scanning narrow frequency bands with the “Bioacoustics” R package signal detection algorithm, and extracting temporal and signal strength parameters from detections. Buzzes were best characterized by the standard deviation of the time between consecutive pulses, the average pulse duration, and the average pulse signal-to-noise ratio. Classification accuracy was highest with artificial neural networks and random forest algorithms. I compared each model’s receiver operating characteristic curves and random forest provided better control over the false-positive rate so it was retained as the final model. When tested on a new dataset, buzzfindr’s overall accuracy was 93.4% (95% CI: 91.5%– 94.9%). Overall accuracy was not affected by recording device type or species frequency group. Automated detection of feeding buzzes will facilitate their integration in the analytical workflow of acoustic bat studies to improve inferences on habitat use and quality.
Preliminary study of microbiologically influenced corrosion by Pseudomonas aeruginosa on high Chromium white iron
Authors: Tan Cedric , Elumalai Naveen Kumar , Krishnan Kannoorpatti Narayanan
Published: August 2024

Microbiologically Influenced Corrosion (MIC) poses a significant challenge to various industries, leading to substantial economic losses and potential safety hazards. Despite extensive research on the MIC resistance of various materials, there is a lack of studies focusing on High Chromium White Iron (HCWI) alloys, which are widely used in wear-resistant applications. This study addresses this knowledge gap by providing a comprehensive investigation of the MIC resistance of three HCWI alloys with varying chromium contents (22 wt%, 30.7 wt%, and 21 wt%) in the presence of Pseudomonas aeruginosa (P. Aeruginosa), a common bacterial species associated with MIC. The alloys were exposed to an artificial seawater medium inoculated with P.Aeruginosa for 14 days, and their corrosion behaviour was evaluated using electrochemical techniques, surface analysis, and microscopy. Electrochemical Impedance Spectroscopy (EIS) results revealed that the alloy with the highest chromium content (A2, 30.7 wt% Cr) exhibited superior MIC resistance compared to the other alloys (A1, 22 wt% Cr and M1, 21 wt% Cr). The enhanced performance of alloy A2 was attributed to the formation of a more stable and protective passive film, as well as the development of a more compact and less permeable biofilm. The EIS data, interpreted using equivalent circuit models, showed that alloy A2 had the highest charge transfer resistance and the lowest biofilm capacitance, indicating a more effective barrier against corrosive species. Bode plots further confirmed the superior corrosion resistance of alloy A2, with higher impedance values and phase angles at low frequencies compared to alloys A1 and M1. Scanning Electron Microscopy (SEM) and optical microscopy analyses corroborated these findings, showing that alloy A2 had the lowest pit density and size after 14 days of exposure. The insights gained from this study highlight the critical role of chromium content in the MIC resistance of HCWI alloys and have significant implications for the design and selection of materials for applications prone to microbial corrosion.

Authors: Paulauskas Rūtenis , Kasparavicius Rokas , Stumbras Mykolas , Figueira Bruno
Published: August 2024

This study aimed to quantitatively assess the statistical contributions between foreign and national players in men’s Euroleague Basketball. Data from 588 games in the 2021–2022 regular season and 612 games in the 2022–2023 regular season were analyzed through non-participant observation. Paired t-tests and Wilcoxon tests were employed to analyse variables with normal and non-normal distributions, respectively. The analysis indicated significant differences (p<0.05) between local and foreign players across several key variables, including Minutes, Points, Average Points, Usage Percentage, Individual Offensive Rating, Individual Defensive Rating, and True Shooting Percentage. These findings suggest pronounced distinctions between foreign players and national players concerning game volume indicators and game performance efficiency. Foreign players exhibited dominance in critical areas, such as playing time, total points scored, and average points per game, underscoring their substantial contributions to their respective teams. Consequently, these results offer practical implications for players, coaches, and fitness trainers, allowing for the design of more tailored training programs that account for distinct offensive and defensive needs, as well as the heightened physical demands experienced throughout the season.
Ambulance quality and outcome measures for general non-conveyed populations (AQUA): A scoping review
Authors: Höglund Erik , Magnusson Carl , Lederman Jakob , Spangler Douglas , Vloet Lilian , Ebben Remco
Published: August 2024

Background

An increasing number of patients receive ambulance care without being conveyed to a definitive care provider. This process has been described as complex, challenging, and lacking in guideline support by EMS clinicians. The use of quality- and outcome measures among non-conveyed patients is an understudied phenomenon.

Aim

To identify current quality- and outcome measures for the general population of non-conveyed patients in order to describe major trends and knowledge gaps.

Methods

A scoping review of peer-reviewed original articles was conducted to identify quality- and outcome measures for non-conveyance within emergency medical services. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews statement (PRISMA-ScR) was followed. The PROSPERO and OSF database were checked for pending reviews or protocols. PubMed, CINAHL, Scopus, Web of Science and the Cochrane Library database were searched for relevant articles. Searches were performed in November 2023.

Results

Thirty-six studies fulfilled the inclusion criteria and were included in the review. Mortality was the most used outcome measure, reported in 24 (67%) of the articles. Emergency department attendance and hospital admission were the following most used outcome measures. Follow-up durations varied substantially between both measures and studies. Mortality rates were found to have the longest follow-up times, with a median follow-up duration a little bit over one week.

Conclusions

This scoping review shows that studies report a wide range of quality and outcome measures in the ambulance setting to measure non-conveyance. Reported quality and outcome measures were also heterogeneous with regard to their follow-up timeframe. The variety of approaches to evaluate non-conveyance poses challenges for future research and quality improvement. A more uniform approach to reporting and measuring non-conveyance is needed to enable comparisons between contexts and formal meta-analysis.

Published: August 2024

Background

In community-acquired pneumonia (CAP), the role of biomarkers to shorten duration of antibiotic treatment has not been firmly established. We assessed the effectiveness of active feedback of treatment algorithms based on procalcitonin (PCT) and C-reactive protein (CRP), compared to standard care, on the duration of antibiotic treatment in patients hospitalized with community-acquired pneumonia (CAP) in non-ICU wards.

Methods and findings

We performed a randomised, open label, parallel group, multi-centre trial in 3 Dutch teaching hospitals. Treatment was guided by a PCT algorithm, CRP algorithm or standard care. Participants were recruited by a member of the study team and randomised at day 2–3 of admission in a 1:1:1 ratio. Treatment was discontinued upon predefined thresholds of biomarkers that were assessed on admission, day 4 and days 5–7 if indicated. The primary outcome was total days on antibiotic treatment until day 30. In total 468 participants were included in this study. The median days on antibiotics (IQR) was 7 (IQR 7–10) in the control group, 4 (IQR 3–7) in the CRP group (rate ratio (RR) of 0.70, 95% CI 0.61–0.82 compared to standard care; p <0.001), and 5.5 (IQR 3–9) in the PCT group (RR of 0.78, 95% CI 0.68–0.89 compared to standard care; p <0.001). New antibiotics within the first 30 days were prescribed to 24, 23 and 35 patients in standard care, CRP and PCT groups, respectively. The hazard ratio for a new prescription in patients in the PCT group compared to standard care 1.63 (CI 0.97–2.75; p = 0.06). No difference in time to clinical stability or length of stay was found.

Conclusions

A strategy of feedback of CRP-guided and PCT-guided treatment algorithms reduced the number of days on antibiotic in the first 30 days after hospital admission in non-ICU wards for CAP. The study was not powered to determine safety of shortening duration of antibiotic treatment. (NCT01964495).
Evaluation of autoimmune liver disease antibodies in hepatitis patients
Authors: Kim Namsoo , Kim Sinyoung , Choi Jong Rak , Park Younhee
Published: August 2024

Background/aims

Autoimmune hepatitis (AIH) is characterized by the presence of auto-antibodies and high blood immunoglobulin G (IgG) levels. In this study, the line immunoassay (LIA) was designed to assess various autoantibodies.

Methods

In total, 1371 patients who underwent autoimmune liver disease antibody testing between July 2019 and November 2022 were enrolled. Autoantibodies including antinuclear antibody (ANA) and anti-mitochondrial antibody (AMA) were tested, and clinical data were collected. Statistical analyses were performed by categorizing the data based on diagnosis and IgG quantification separately. A scoring system was applied to identify individuals with AIH. Patients were also classified into the AIH and non-AIH groups.

Results

The positivity rate for ANA was 80.2% in the AIH group. The IgG-high group had a high likelihood of the presence of detectable autoantibodies, with anti-Ro-52 being the most frequently detected antibody using LIA. The "Consider AIH" and "AMA" groups had 3–4 times more patients in the IgG-high group than in the "Not Considered" group.

Conclusions

Among autoantibodies, the prevalence of ANA was the highest. As per LIA results, anti-Ro-52 was the most prevalent. AIH cannot be diagnosed based on IgG levels alone and must be distinguished via autoantibody testing. Therefore, extensive testing, including autoantibodies, IgG, ANA, and liver enzyme levels, will help accurately diagnose AIH.

Published: August 2024

Nuclear receptor binding SET domain protein 2 (NSD2) significantly contributes to the development of cancer, making it a promising target for cancer drug discovery. This research explores natural compounds as potential selective inhibitors for NSD2 in cancer treatment. Employing a comprehensive in silico approach, the study utilized pharmacophore modeling, molecular docking, pharmacokinetic profiling, and molecular dynamics simulations. An e-pharmacophore model-based screening using the first selective and potent ligand bound to NSD2 identified 49,248 natural compounds from the SuperNatural 3.0 database (containing 449,008 molecules) with acceptable alignment with the developed pharmacophore hypotheses. Subsequently, molecular docking was executed to assess the standout compounds which led to the selection of ten candidates that surpassed the reference inhibitor in accordance w the binding affinity expressed as a G score. Ligand-residue interaction analyses of the top three hits (SN0450102, SN0410255, and SN0142336) revealed diverse crucial interactions with the NSD2 active site, including hydrogen bonds, pi-pi stacking, and hydrophobic contacts with key amino acid residues in the NSD2-PWWP1 domain. Pharmacokinetic profiling confirmed the drug-likability for the refined hits, indicating good cellular permeability and minimal blood-brain barrier penetration. Molecular dynamics simulations for 200 nanoseconds affirmed the stability of protein-ligand complexes, with minimal fluctuations in root mean square deviation and root mean square fluctuation analyses. Overall, this study identified promising natural compounds as potential pharmaceutical agents in the treatment of NSD2-associated cancers.
“I do think that accessibility is a really major thing that has come [out] of [the] pandemic”: The lived experiences of resilience and health-related quality of life among a diverse sample of graduate students during the COVID-19 pandemic

Published: August 2024

The COVID-19 pandemic has negatively impacted the mental health and wellbeing of post-secondary students. Resilience has been found to serve as a protective factor against mental distress among students during the pandemic. Despite the plethora of research that exists on post-secondary students during this crisis, most studies exploring students’ health and resilience are quantitative and lack diversity. To date, the lived experiences of health-related quality of life (HRQOL) and resilience among graduate students representing diversity in age, gender, ethnicity, parental status, university, degree, and faculty during the COVID-19 pandemic remain unknown. As a part of a larger study, the purpose of this qualitative paper was to understand the lived experiences of resilience and HRQOL among a diverse sample of graduate students approximately 18 months into the COVID-19 pandemic in Ontario, Canada. A total of 14 students participated in semi-structured interviews exploring HRQOL domains, factors that supported/undermined participants’ resilience, challenges/barriers to being resilient, and participants’ inner strength. Thematic analysis revealed 5 themes: (1) cultural influences on resilience; (2) the role of privilege/power in shaping resilience; (3) how life stage and past experiences support resilience; (4) how the COVID-19 pandemic has undermined the resilience of equity-deserving groups; and (5) the role of disability/chronic pain. This work presents a unique dichotomy between how the COVID-19 pandemic has disrupted the lives of some graduate students, while simultaneously creating opportunities for others to thrive. Findings from this work underscore the importance of creating inclusive and accessible educational spaces to support graduate students’ resilience and HRQOL currently, and in times of crisis.

Published: August 2024

According to the National Telecommunications Agency (ANATEL), in a report released in 2022, it detailed that around 63% of fixed broadband connections used fiber optic networks for connection. This report demonstrates the constant expansion of fiber optic networks in Brazil. The high demand for optical networks means that internet providers face challenges in delivering a quality service that provides a positive customer experience. As a result, companies in the sector have been looking for solutions to solve problems in connecting optical networks. Currently, in the literature and on the market, there are techniques and tools that enable providers to monitor the network connection, carry out speed tests, promote customer service and carry out preventive maintenance. One of these commercial tools is the Optical Power Meter (OPM), a device capable of taking optical measurements in fiber optic networks. Therefore, this work aims to develop an optical power measurement system for passive fiber optic networks, in order to analyze the quality of the signal provided to users, which uses the LoRaWAN communication protocol, thus integrating with the Internet of Things (IoT).

INTRODUCTION:

Colonoscopy surveillance for Lynch syndrome is burdensome and postcolonoscopy colorectal cancers (CRCs) still occur. The noninvasive fecal immunochemical test (FIT) might guide optimal colonoscopy intervals.

METHODS:

Prospective, multicenter observational study in which individuals with Lynch syndrome performed a quantitative FIT before high-quality surveillance colonoscopy. Diagnostic performance of FIT at various thresholds ≤20 μg Hb/g feces was assessed for relevant neoplasia, including advanced neoplasia (CRC, advanced adenomas [AAs] and advanced serrated lesions [ASLs]) and non-advanced adenomas (NAAs).

RESULTS:

Of the 217 included individuals (59% female, median age 51 years), 4 had CRC, 5 AA, 4 ASL, and 57 NAA as most relevant neoplasia. The lowest FIT positivity threshold (2.5 μg Hb/g feces, 14% positivity rate) maximized detection: 4/4 CRCs, 4/5 AA, 1/4 ASL, and 9/57 NAA were detected, resulting in a sensitivity and negative predictive value of, respectively, 89% and 99% for CRC plus AA, 69% and 97% for advanced neoplasia, and 26% and 72% for all relevant neoplasia (91% specificity for all groups). At equal sensitivity and negative predictive value, specificity for advanced neoplasia optimized to 94% at threshold 4.1 μg/g. Per 100 FITs at threshold 4.1 μg/g, 11 individuals would test positive and thus proceed to colonoscopy, 2 individuals with advanced neoplasia would be missed and 3 individuals would need colonoscopy to detect 1 advanced neoplasia.

DISCUSSION:

FIT at thresholds ≤4.1 μg Hb/g feces may be a promising strategy to postpone colonoscopy in approximately 9 of 10 individuals with Lynch syndrome. Large validation studies that also provide gene variant-specific outcomes should be prioritized.

Para tanto, partimos de uma Análise de Conteúdo, mesclando elementos quantitativos e qualitativos, a fim de obter as respostas para as perguntas geradoras deste trabalho. Ao final, foi possível notar não apenas a forma, mas também obter pistas das finalidades sob as quais os vereadores utilizam esses espaços comunicacionais, assim como constatar a completa ausência da pauta racial no período analisado, o que abriu caminho para um debate acerca da racialização e desracialização na pauta política local.
Perturbation method for laminar flow of viscous incompressible fluid between two porous boundary walls
Authors: Chandra Ray Samir , Biswas Anik
Published: August 2024

The present study focuses on the investigation of the velocity profile of viscous fluid between two parallel porous walls while fluid is being ejected from both channel walls at the same rate. The distributions of velocity, pressure and shear stress were determined theoretically for incompressible, steady, fully developed laminar flow past a porous boundary wall. Due to the pressure difference across the porous wall, there is ejection or injection into the wall. The velocity specified as the boundary condition at the wall has been used to explore fluid flow phenomena in porous tubes and ducts. The variable wall velocity is based on the pressure differential across the wall, the fluid characteristics, the thickness of the wall, and the permeability of the structure. An appropriate wall condition must take these factors into account. This paper discusses a Reynolds number solution. We seek formulas for the velocity component. The perturbation approach is used to solve the governing differential equation and the general solution of the velocity is obtained for higher terms of Re. Fifth term of perturbation is used in the perturbation method. The velocity of the fluid is analyzed for different values of Re for a boundary condition. Finally, the result is analysis graphically for the range of Re from .1 to 50. In addition, another strategy is used to keep the Reynolds number constant when the diameter of the hole in the porous wall changes, i.e., changing the value of λ.

Eisenstein degeneration of Euler systems
Authors: Loeffler David , Rivero Salgado Oscar
Published: August 2024

We discuss the theory of Coleman families interpolating critical-slope Eisenstein series.
We apply it to study degeneration phenomena at the level of Euler systems.
In particular, this allows us to prove relations between Kato elements, Beilinson–Flach classes and diagonal cycles, and also between Heegner cycles and elliptic units.
We expect that this method could be extended to construct new instances of Euler systems.
Ding stability and Kähler–Einstein metrics on manifolds with big anticanonical class
Authors: Dervan Ruadhaí , Reboulet Rémi
Published: August 2024

We introduce a notion of uniform Ding stability for a projective manifold with big anticanonical class, and prove that the existence of a unique Kähler–Einstein metric on such a manifold implies uniform Ding stability. The main new techniques are to develop a general theory of Deligne functionals – and corresponding slope formulas – for singular metrics, and to prove a slope formula for the Ding functional in the big setting. This extends work of Berman in the Fano situation, when the anticanonical class is actually ample, and proves one direction of the analogue of the Yau–Tian–Donaldson conjecture in this setting. We also speculate about the relevance of uniform Ding stability and K-stability to moduli in the big setting.

Polyvinyl alcohol (PVA) is well-known for its excellent mechanical properties and eco-friendliness in food packaging. Recently, PVA has gained significant attention in research due to its potential as antibacterial substrates. However, because of its high hydrophilicity, practical application of pure PVA film has been limited by low water resistance and rapid bacterial growth in humid conditions. Diverse effective strategies have been developed to decrease hydrophilicity and endow films with antibacterial properties. This review provides an overview of universal antibacterial agents and their functions in PVA-based packaging films. It also introduces the changes in the mechanical and physical properties of PVA-based films after adding antibacterial agents. Additionally, the release behavior of antibacterial agents in PVA-based film materials and their practical applications in the food industry is discussed in fresh food packaging. Biodegradability of PVA-based films is also mentioned, with a promising future for more effective and eco-friendly food packaging materials.
Possible impact of construction activities around a permanent GNSS station – A time series analysis
Authors: Aarnes Per Helge , Øvstedal Ola , Rost Christian
Published: August 2024

In this article, we address the potential effects of construction activities around a permanent Global Navigation Satellite System (GNSS) station. The study is based on a consistent time series of GNSS observations collected over a span of almost 13 years and comprises an analysis in both observation and coordinate domains. The analysis in the observation domain revealed a significant increase of the code multipath for the C1C signal of GPS and GLONASS. In terms of standard deviations the values increased by 37 and 31%, respectively. No significant increase was observed for other signals. Interestingly, the analysis showed that the Galileo E5 AltBOC signal outperformed the other signals in distinguishing direct from indirect signals. In the coordinate domain, the relative GNSS solution results demonstrated an increase in root mean square error for the eastern component during the same period. Noteworthy, the observed increase in both domains coincided with the period of the highest level of construction activity around the GNSS station. These findings suggest that the construction activity near the station impacted the quality of GNSS observations and that the Galileo E5 AltBOC signal was better at compensating for local changes than other signals.

Objectives

To compare the effectiveness, safety and patient satisfaction of a double balloon catheter (DB) with a synthetic osmotic cervical dilator (OD) for pre-induction cervical ripening in an outpatient setting.

Methods

This is a prospective, dual-center pilot study including 94 patients with an unripe cervix (Bishop Score <6) near term; 50 patients received the DB and 44 patients the OD. The primary outcomes were the difference in BishopScore (BS) and cervical shortening. Pain perception at insertion and during the cervical ripening period was evaluated by a visual analogue scale and patient satisfaction by a predefined questionnaire.

Results

The use of DB was associated with a significantly higher increase in BS (median 3) compared to OD (median 2; p=0.002) and resulted in significantly greater cervical shortening (median −14 mm vs. −9 mm; p=0.003). There were no serious adverse events at placement of devices or during the cervical ripening. There were no significant differences in perinatal outcomes. Pain perception during cervical ripening was significantly higher (p<0.001), and patient satisfaction regarding sleep, relaxing time and performing desired daily activities were significantly lower in patients with DB compared to patients with OD (p<0.001).

Conclusions

DB was superior to OD regarding cervical ripening based on BS and on sonographic measurement of the cervical length. Patients with OD experienced less pain during cervical ripening and were more satisfied with the method compared to patients with DB.
Solving multi-point problem for Volterra-Fredholm integro-differential equations using Dzhumabaev parameterization method
Authors: Bakirova Elmira A. , Assanova Anar T. , Kadirbayeva Zhazira M.
Published: August 2024

In this study, a multipoint boundary value problem for Volterra-Fredholm integro-differential equations is considered. The addition of a new function converts the system of Volterra-Fredholm integro-differential equations to a system of Fredholm integro-differential equations. In contrast to the original problem, the dimension of a Fredholm integro-differential equation is determined by the number of matrices in the degenerate kernel of the Volterra integral. A numerical algorithm of Dzhumabaev parameterization method for addressing a multipoint boundary value problem for Volterra-Fredholm integro-differential equations is proposed. The main advantage of the proposed method is splitting the problem into auxiliary Cauchy problems for ordinary differential equations and a system of algebraic equations with respect to the parameters. The conditions for the unique solvability of the multipoint boundary value problem for Fredholm integro-differential equations are established. Finally, various numerical examples are provided to demonstrate the efficiency and correctness of the suggested technique.

Published: August 2024

This article aims to use passive flow control to analyze the transportation of heat, mass, and charged particles toward a 3D plate. The current problem offers a novel exploration of the flexible domain of non-Newtonian materials, which are well known for their wide range of applications in the engineering and industrial domains. The current study explores the complex dynamics of heat and mass transfer in a fluid that flows over an elongating sheet. The motion of the nanofluid on the surface is caused by the stretching of the 3D plate. The suspension of mixtures of tetra-hybrid nanoparticles can enhance thermal performance and cooling mechanism. Moreover, the 3D model includes modeling of multiple important parameters, such as heat source, thermal radiation, and Hall and Ion slip effects, in Cartesian coordinates for a three-dimensional stretched plate. This comprehensive analysis of various effects offers a new perspective to the field. Partial differential equations represent the emergent phenomena in the problem formulation process. It was estimated that an enhancement of charged particles and motion regarding nanoparticles is enhanced versus an enhancement of charged particles. With the greater power law index, suction, and Weissenberg number, the acceleration of nanoparticles is enhanced.
