Application of experimental planning methods for an analytical description of the areas of operability of marine electromechanical systems
Authors: Saushev A. V.
Published: October 2024

The topic of the study is to consider the possibility of using experimental planning methods to mathematically describe areas of performance in relation to marine electromechanical systems. A definition is given and a graphic illustration of the field of operability is provided. It is shown that information about the boundary of the field of operability allows solving the most important tasks of controlling the state of ship electromechanical systems of various functional purposes. Possible ways of solving the problem of constructing a field of efficiency and the difficulties of their practical implementation are given. The method of analytical description of the operability domain is considered, which assumes an independent approximation of each hypersurface that makes up the operability domain. It is shown that for such an approximation it is convenient to use polynomial dependencies, which can be obtained as a result of using experimental planning methods. The main advantages of this approach are considered, including the possibility of solving the problem in the case of a high dimension of the space of primary parameters, in the space of which the area of operability is built. It is noted that in order to obtain a unified analytical description of the field of operability, the properties of logical R-functions can be used, which make it possible to make the transition from logical functions to analytical dependencies. It is proved that polynomial dependencies have the properties of R-functions and can be used in such a transformation. The resulting analytical description of the health area is universal and does not depend on the configuration of the area itself. Unlike the known methods of analytical approximation of the field of operability, it is characterized by an exceptionally low methodological error and allows us to solve with high reliability the problem of parametric synthesis of marine electromechanical systems according to the criterion of the reserve of operability, as well as the tasks of evaluating and predicting their condition during operation. The considered example clearly demonstrated the sequence of solving the problem of analytical description of the field of operability and allowed us to conclude about the complex configuration of this area even for special cases and the simplest electromechanical systems.

Reinforcement Learning to Optimize Ventilator Settings for Patients on Invasive Mechanical Ventilation: Retrospective Study (Preprint)
Authors: Liu Siqi , Xu Qianyi , Xu Zhuoyang , Liu Zhuo , Sun Xingzhi , Xie Guotong , Feng Mengling , See Kay Choong
Published: October 2024

BACKGROUND

One of the significant changes in intensive care medicine over the past 2 decades is the acknowledgment that improper mechanical ventilation settings substantially contribute to pulmonary injury in critically ill patients. Artificial intelligence (AI) solutions can optimize mechanical ventilation settings in intensive care units (ICUs) and improve patient outcomes. Specifically, machine learning algorithms can be trained on large datasets of patient information and mechanical ventilation settings. These algorithms can then predict patient responses to different ventilation strategies and suggest personalized ventilation settings for individual patients.

OBJECTIVE

In this study, we aimed to design and evaluate an AI solution that could tailor an optimal ventilator strategy for each critically ill patient who requires mechanical ventilation.

METHODS

We proposed a reinforcement learning–based AI solution using observational data from multiple ICUs in the United States. The primary outcome was hospital mortality. Secondary outcomes were the proportion of optimal oxygen saturation and the proportion of optimal mean arterial blood pressure. We trained our AI agent to recommend low, medium, and high levels of 3 ventilator settings—positive end-expiratory pressure, fraction of inspired oxygen, and ideal body weight–adjusted tidal volume—according to patients’ health conditions. We defined a policy as rules guiding ventilator setting changes given specific clinical scenarios. Off-policy evaluation metrics were applied to evaluate the AI policy.

RESULTS

We studied 21,595 and 5105 patients’ ICU stays from the e-Intensive Care Unit Collaborative Research (eICU) and Medical Information Mart for Intensive Care IV (MIMIC-IV) databases, respectively. Using the learned AI policy, we estimated the hospital mortality rate (eICU 12.1%, SD 3.1%; MIMIC-IV 29.1%, SD 0.9%), the proportion of optimal oxygen saturation (eICU 58.7%, SD 4.7%; MIMIC-IV 49%, SD 1%), and the proportion of optimal mean arterial blood pressure (eICU 31.1%, SD 4.5%; MIMIC-IV 41.2%, SD 1%). Based on multiple quantitative and qualitative evaluation metrics, our proposed AI solution outperformed observed clinical practice.

CONCLUSIONS

Our study found that customizing ventilation settings for individual patients led to lower estimated hospital mortality rates compared to actual rates. This highlights the potential effectiveness of using reinforcement learning methodology to develop AI models that analyze complex clinical data for optimizing treatment parameters. Additionally, our findings suggest the integration of this model into a clinical decision support system for refining ventilation settings, supporting the need for prospective validation trials.

Salvador Allende, una reinterpretación del mito
Authors: Sepúlveda-Cereceda Alfredo
Published: October 2024

El último discurso de Salvador Allende marca el inicio del mito y de su legado político, que se debate entre: la visión de Allende como un líder socialdemócrata adelantado a su tiempo, intentando llevar a cabo un proceso socialista por vías pacíficas y legales, y la percepción de él como un revolucionario totalitario. La "vía chilena al socialismo" tenía como objetivo traspasar la riqueza de la burguesía a los trabajadores, pero su implementación enfrentó desafíos legales y violencia que serán abordados en el presente ensayo.

Islamic Microfinance Institutions (IMI) have a strategic role with their main function being to collect funds from people with excess funds and channel the funds to people in need effectively and efficiently. The existence of IMI is expected to help people, especially those from the lower middle class, in gaining access to funding. However, the perception and attitude of the community towards bank interests and the profit sharing system show diversity. Some people still choose to accept interest and consider it the same as the profit sharing system, so an analysis of factors that influence the community's interest in using IMI products is needed. The purpose of this study was to determine the effect of knowledge, promotion, service quality, and religiosity on the community's interest in using IMI products in Lamongan. The sample used was 100 samples selected using the purposive sampling method. The data was processed using multiple linear regression analysis techniques. The test results stated that partially and simultaneously, the variables of knowledge, service quality, promotion, and religiosity had a positive effect on the community's interest in using IMI products in Lamongan.

Published: October 2024

Evidence on the benefits of consuming a whole food, plant-based (WFPB) dietary pattern for overall health and chronic disease prevention and remission is mounting. A large amount of evidence supports plant-predominant nutrition with significant con- tributions to the research coming from the Adventist Health Studies (AHS) at Loma Linda University Health (LLUH). The totality of evidence on plant-predominant nutrition has influenced guideline changes by the American College of Cardiology and the American Medical Association to strongly recommend hospitals offer plant-based nutrition to patients. A knowledge translation project was spearheaded at LLUH to adopt evidence-based research into acute care while also meeting emerging guidelines and regulations. A therapeutic inpatient menu comprised of whole plant foods with no added oils or refined sugars and low in sodium for the purpose of adjunct treatment of acute illness management was developed. Multidisciplinary team development, key stakeholder involvement, and applying effective strategies to overcome challenges were crucial in implementing system-wide changes to align the best nutritional evidence with clinical practice.

Background and Objectives: Case reports are a popular publication type, especially for medical learners. They also are an excellent educational vehicle that can spark a long-term interest in scholarship for medical learners. To maximize publication potential, authors need a framework when writing a case report.
Methods: We did a manifest content analysis on case reports published in 12 peer-reviewed medical journals between 2010 and 2019. We classified the case reports as detection, extension, diffusion, or fascination. The objective of our study was to determine whether case reports can successfully be classified by their primary contribution to the medial literature as detection, extension, diffusion, or fascination case reports.
Results: Using a predefined search strategy, we identified 1,005 manuscripts identified as case reports published from 2010 to 2019 in 12 journals from a variety of medical specialties. Only 673 of the 1,005 (67.0%) met our criteria for a case report. Of these, 59.1% most closely fit the category of diffusion case reports. Fascination case reports were the least common (1.2%). The format of published case reports varied widely among journals.
Conclusions: Case reports can be categorized according to their main contribution to the medical literature. Nearly 60% of all published case reports in this study were not published for the purpose of introducing a novel clinical entity. Instead, they were used as a vehicle to educate clinicians about previously described phenomena. Authors seeking to publish case reports should understand how the framing of their report is likely to influence their chances of being published.

Contextualización: el cacao en Colombia es un cultivo de relevancia no solo por su factor económico, sino por su entorno social y ambiental. Según la Gobernación del Huila (2022) se estima que el cacao en el huila es el sustento de alrededor de 3300 familias, con 7000 hectáreas sembradas aproximadamente. Respecto al manejo fitosanitario de este cultivo se destaca la enfermedad causada por Phytophthora spp. como una de las enfermedades más limitantes para la producción (Rodríguez y Vera, 2015). Vacío de conocimiento: en Colombia son escasas las investigaciones realizadas para conocer la relación de los clones y el desarrollo de la enfermedad Phytophthora spp., por lo que este tipo de estudios son requeridos con urgencia en la zona de influencia del proyecto; en ese sentido, se han realizado avances investigativos en clones por parte de AGROSAVIA, pero en otras regiones del país. Propósito: el objetivo del presente estudio fue evaluar la incidencia de Phytophthora spp. en clones de cacao, con aplicaciones de Trichoderma sp. en condiciones ambientales del departamento del Huila, para contribuir con la línea de investigación en biotecnología agrícola. Metodología: se emplearon parámetros de evaluación para incidencia y severidad de Phytophthora spp. en 10 clones de cacao: EET 8, TSH 565, SCC 61, ICS 1, ICS 95, HIBRIDO, IMC 67, ICS 39, ICS 60 y CCN 51. Enfermedad tratada con: T1: (Trichoderma asperellum, Trichoderma atroviridae, Trichoderma harzianum). Presentación polvo mojable PW. T2: (Trichoderma viride), presentación líquida suspensión concentrada SC. T3: Testigo, sin ninguna aplicación, en dos épocas de producción fase I (13, 20 y 27 de diciembre) y fase II (14, 21 y 28 de mayo). Resultados y conclusiones: Se concluye que los efectos sobre Phytophthora spp. responden a la combinación de la susceptibilidad del material vegetal empleado y la acción del Trichoderma spp. en el cultivo de cacao. En la fase II hay una diferencia significativa entre el testigo y el tratamiento en polvo, frente al tratamiento líquido siendo este último el que ejerce mejor control sobre la enfermedad.
The influence of corporate governance on environmental, social, and government disclosure: Empirical evidence on the European Union banking industry
Authors: Capuano Paolo
Published: October 2024

This study evaluates the impact of corporate governance on environmental, social, and governance (ESG) disclosure in the banking industry. This aspect has been little investigated in the business literature and there are even fewer empirical studies on the European Union (EU) banks. The analysis methodology is based on an empirical analysis, using a dynamic generalized method of moments and quantile regression analysis, on a large sample of EU banks over the period 2014–2023. The first results highlight that some governance variables are factors that positively influence the overall levels of ESG disclosure of EU banks. The study would encourage banks to carefully define their internal corporate governance mechanisms, paying particular attention, especially to the careful selection of board members.

Authors: Bashir Mohamed Sharif , Muslichah Muslichah , Babiker Abdo Aglan
Published: October 2024

This study investigates the relationship between governance dimensions and the level of commitment to the Shariah (Islamic law) governance framework in Saudi banks. To understand the intricacies of governance dimensions in shaping Shariah governance practices in depth, this study also examines the mediating role of executive procedures between governance dimensions and commitments to the Shariah governance framework. Structural equation modeling is used to test the hypotheses regarding the relationship between studied variables. The findings underscore the significance of the availability of executive procedures and disclosure and transparency in fostering commitments to the Shariah governance framework, with both constructs exhibiting substantial direct effects on the Shariah governance commitment level. Additionally, monitoring, auditing, and accountability emerged as crucial determinants of governance in banks, highlighting the importance of robust oversight mechanisms in ensuring adherence to Shariah principles. Meanwhile, organizational structure exhibited a minor decrease in its direct effect on commitment to Shariah governance. The findings of this study can guide the strategic decision-making process for promoting ethical and sustainable Shariah governance practices in Saudi banks.

when the sintering temperature was varied between 1410 and 1430 ?C and the
comprehensive performances of the ceramics were the best in this temperature
range. In order to confirm that the coarse grain WC-Ni-Co ceramics can be
applicable for harsh environments, it was compared with the standard WC-Co
ceramics of the same grain size, and the reasons and mechanisms for the
differences in microstructure and properties between the two ceramics were
tested and analysed. The study shows that the average grain size of two
ceramics does not differ much, and there are no decarburisation,
graphite-phase and other impurity phases inside the ceramics. In addition,
the difference in the mechanical properties is also small. However, the
addition of Ni effectively improves the corrosion resistance of the WC-Co
ceramics. Therefore, WC-Ni-Co can replace WC-Co ceramics as shield cutting
tool material with the same grain size.

A creative and environmentally friendly preparation of high-porosity
open-cell ceramic foams was investigated. The samples were prepared from the
?-Al2O3 slurry with 25 wt.% solid loading in which a tiny amount of boehmite
(?-AlO(OH)) sol was added for the formation of particle-stabilized foams
without introducing any sacrificial phases. The volumetric shrinking of
?-AlO(OH) enables the formation of open-cell while avoiding the generation of
polluting gases. The resulting alumina ceramic foams have a synergistic
increase in porosity and compressive strength, reaching a compressive
strength of 1.17MPa and an ultra-high porosity of 94.8%. This is due to the
fact that the pore struts (connecting neighbouring cells) are almost
defect-free, while the high sintering activity of ?-AlO(OH) promotes the
sintering of ceramic phase and formation of alumina with small grains which
has the strengthening effect on the obtained structures. By achieving
open-cell, the heat conduction path increased, which reduces the thermal
conductivity of the ceramic foam. This work provides an alternative and
environmentally friendly new strategy for open-cell ceramics processing.

Al2O3/Ti/Ni composites, enhanced with the inclusion of NiAl2O4 and TiAl2O5
phases, represent a novel class of advanced materials with multifaceted
properties suitable for diverse engineering applications. Centrifugal slip
casting method was used for preparation of two series of gradient
Al2O3/Ti/Ni composite samples with different content of the metallic Ti and
Ni phases. Series I containing 0.5 vol.% of Ni and 0.5 vol.% of Ti and
Series II containing 2.5 vol.% of Ni and 2.5 vol.% of Ti. Each series
contained 55 vol.% of a solid phase. Rheological properties of the
suspensions as well as microstructure of the obtained composites were
studied, with special attention paid to the analysis of the formed spinel
phases. Both series in the green form were characterized by 3-zone structure
with different metallic phase content. The widths of individual zones for
the Series I and Series II, after sintering at 1450?C, were 0.53mm (zone
I), 3.26mm (zone II), 0.8mm (zone III) and 1.27mm (zone I), 1.47mm (zone
II), 1.87mm (zone III), respectively. The results showed that after
sintering two spinel phases were formed. The NiAl2O4 spinel phase consists
only of small grains with a size of approximately 1.3- 1.8 ?m, which form
larger clusters with or without a void inside. The TiAl2O5 phase consists of
grains with an average size of 4.3 to 4.5 ?m. The Life Cycle Assessment
analysis revealed that the values of the global warming potential indicator
in phase A1 are 0.16 kg and 0.20 kg equivalent of CO2 per sintered sample
for the Series I and Series II, respectively.

Ceramic cores for high-pressure turbine airfoil blades in aircraft engines
are characterised by very complicated shapes and the presence of small
diameter holes and thin long grooves. In this paper, eight starting powder
mixtures having different contents of fused silica, zirconium silicate,
alumina and borosilicate glass were used for preparation of core material.
The composition, which satisfies every demand for core application in the
investment casting of high-pressure turbine blades, contains 69.0wt.% fused
silica, 13.0 wt.% zirconium silicate, 12.0wt.% alumina and 6.0wt.%
borosilicate glass. This material was characterised by a mechanical strength
of 33.1MPa, a coefficient of thermal expansion of 2.56 ? 10?6 1/K, surface
roughness of 1.8 ?m, shrinkage of less than 0.8% and an average pore size
diameter of 2.7 ?m. The thin-walled ceramic cores were formed by the
high-pressure injection moulding method, which required the selection of a
thermoplasticiser, feedstock formulation and determination of the optimal
processing conditions protecting the injected cores from defects and
deformation. The post-shaping process of the cores included both water and
thermal debinding, sintering, precision machining and dimension
measurements.

Objective: Gestational diabetes mellitus (GDM) increases the risk of fetal overgrowth, as measured by two-dimensional (2D) ultrasonography. Whether fetal 3D soft tissue and organ volumes provide additional insight into fetal overgrowth is unknown.

Research Design & Methods: We prospectively evaluated longitudinal 3D fetal body composition and organ volumes in a diverse US singleton pregnancy cohort (2015-2019). Women were diagnosed with GDM, impaired glucose tolerance (IGT), or normal glucose tolerance (NGT). Up to five 3D ultrasound scans measured fetal body composition and organ volumes; trajectories were modeled using linear mixed models. Overall and weekly mean differences in fetal 3D trajectories were tested across glycemic status, adjusted for covariates.

Results: In this sample (N=2427), 5.2% of women had GDM and 3.0% had IGT. Fetuses of women who developed GDM, compared to NGT, had larger fractional arm and fractional fat arm volumes from 26-35 weeks, smaller fractional lean arm volume from 17-22 weeks, and larger abdominal area from 24-40 weeks. Fetuses of women with IGT had similar growth patterns, but manifested later in gestation and with larger magnitudes, and had larger fractional lean arm volume. No overall differences were observed among thigh or organ volumes across glycemic status.

Conclusions: Body composition differed in fetuses of GDM pregnancies, including larger arm and abdominal measures across the second and third trimesters. Patterns were similar in IGT pregnancies except occurred later in gestation and with larger magnitudes. Future research should explore how lifestyle and medication may alter fetal fat accumulation trajectories among hyperglycemic pregnancies.

Objective: This longitudinal pilot study aimed to evaluate the feasibility, safety and potential benefits of Platelet-Rich Plasma injections into the lumbar intervertebral discs in patients with low back pain and degenerative intervertebral monodiscopathy, assessing potential efficacy on disability.
Design: Longitudinal pilot study.
Methods: Six participants with chronic low back pain and lumbar degenerative intervertebral disc (monodiscopathy) disease underwent 1 Platelet-Rich Plasma injection, with a 1-year follow-up. Platelet-Rich Plasma injections were administered into the lumbar intervertebral disc, and outcomes were measured using the Roland Morris Disability Questionnaire, numeric rating scale for pain, Tampa scale for kinesiophobia and lumbar flexion range. Magnetic resonance imaging analysis assessed disc changes.
Results: No adverse events were reported. At the end of the 1-year follow-up, half of the patients showed significant improvements in disability scores at 1 year, while 3 of the 6 patients had no change. Magnetic resonance imaging revealed no significant disc changes.
Conclusion: Platelet-Rich Plasma injections show promise for some patients with low back pain and degenerative intervertebral discopathy patients. However, caution is warranted due to study limitations, including small sample size and lack of a control group. Further research is needed to define Platelet-Rich Plasma therapy protocols.
