IARMTS: Design of an Interference-Aware Routing Model with Time Synchronization Capabilities for Dense Wireless Sensor Network Deployments
Authors: Shrivastav Ritesh , Karmore Swapnili
Published: July 2023

Performance of dense wireless sensor networks is often degraded due to communication interference and time synchronization issues. Existing machine learning & deep learning models that propose bioinspired & pre-emptive packet-analysis solutions for these tasks either have high complexity, or high deployment costs. Moreover, these models cannot be scaled for heterogeneous node & traffic types, which limits their applicability when applied to real-time scenarios. To overcome these issues, this text proposes design of an interference-aware routing model with time synchronization capabilities for dense wireless sensor network deployments. The network initially collects temporal clock states & packet delivery performance of different nodes on heterogeneous traffic scenarios. These traffic patterns are converted into frequency, entropy, Gabor, and Wavelet components. The converted components are used to train an ensemble set of Naïve Bayes (NB), k Nearest Neighbour (kNN), Multilayer Perceptron (MLP), and Support Vector Machine (SVM) classifiers. These classifiers assist in identification of optimal clock deviations and set of routing paths. These routing paths are further fine-tuned via use of a Bacterial Foraging Optimization (BFO) Model, which assists in identification of interference-aware paths. The BFO Model uses a temporal fitness function that fuses throughput, communication delay, energy levels, and packet delivery performance for different set of contextual communications. Due to which, the model is able to showcase lower end-to-end delay, higher throughput, lower energy consumption, and higher packet delivery performance when compared with existing routing methods under high density nodes & heterogeneous network scenarios. The model showcases 99% PDR, 18.3% lower delay, 19.5% higher energy efficiency and 10.4% lower delay levels when compared with existing methods.

Published: July 2023

This study aims to find out in depth about the social emotional development of children out of wedlock at the Pondok Pesantren Metal Rejoso Pasuruan. The informants of this research were the kiai and ustad of the Islamic Boarding School of Metal Rejoso Pasuruan and children illegitimate, in this case they were students from the pesantren. The research methodology uses descriptive phenomenology with a psychological approach. The process of collecting data through interviews, observation, and documentation. The technical analysis of the data is through the stages of Horizontalizatio, Developing clusters of meaning, Textural description, Structural description, and Essentialization. The theory as an analysis tool uses Hurlock's theory of social development. The results of this study indicate that the formation of personality and social-emotional children out of wedlock is education and training (Riyadhoh) which is implemented by kiai and accompanied by ustadz. As well as making the position of the kiai as their parents and fellow students as their siblings, so that they feel they have a family that is ready to pay attention to their social emotional development until they are adults. The implication of his theory is that real families are not bound by biological families as Hurlock argues, but by people who are able to provide a stable group of people with a feeling of security, able to be relied upon to meet their needs, a source of love and acceptance, who are not affected by what they do, guide them. teach approved social behavior, able to help solve problems faced by each child in adjustment to life, so as to achieve success in social life, accept aspirations, develop talents and abilities to be friends.

Invention Arising From Surgical Service Needs; Stoma Bag Cover
Authors: GUZELYUZ Betul , ULUDAĞ Server Sezgin
Published: July 2023

Aim: In cases such as colostomies, enterocutaneous fistulas and catheters leaking fluid from the environment; the use of stoma bags is necessary. The aim of this study; it is to present the invention called “stoma bag cover” that can be used instead of laborious applications such as opening the stoma bag completely to make an enema or puncturing the bag for drainage.
Material and Methods: Stoma bag cover is a cover that can be placed in the anterior middle part of the stoma bags and provides an opening through which catheters can come out. In addition, in order to prevent leakage around the drain, there is a nylon structure prepared with a purse-shaped thread around the inside of the cover. By knotting this nylon structure after the drain or catheter is passed through the thread at the end, the space that will cause leakage around the drain is eliminated. In addition, if the need for the opening in the stoma bag ends, the cover is designed to be closed and leakproof.
Results: Stoma bag cover; it provides a more practical and effective mechanism for applications that are sometimes insufficient to prevent leakage, such as tying and taping applied to drains removed from the stoma bag. In addition, this invention is a valve mechanism that can enable some necessary applications without opening the stoma bag completely without contamination.
Conclusion: It is expected that this invention will provide healthier results and comfort compared to previous applications, both by providing ease of application and reducing contamination.
Evidence for Thermal X-Ray Emission from the Synchrotron-dominated Shocks in Tycho’s Supernova Remnant
Authors: Ellien Amaël , Greco Emanuele , Vink Jacco
Published: July 2023

Young supernova remnant (SNR) shocks are believed to be the main sites of galactic cosmic-ray production, showing X-ray synchrotron-dominated spectra in the vicinity of their shock. While a faint thermal signature left by the shocked interstellar medium (ISM) should also be found in the spectra, proofs for such an emission in Tycho’s SNR have been lacking. We perform an extended statistical analysis of the X-ray spectra of five regions behind the blast wave of Tycho’s SNR using Chandra archival data. We use Bayesian inference to perform extended parameter space exploration and sample the posterior distributions of a variety of models of interest. According to Bayes factors, spectra of all five regions of analysis are best described by composite three-component models taking nonthermal emission, ejecta emission, and shocked ISM emission into account. The shocked ISM stands out the most in the northern limb of the SNR. We find for the shocked ISM a mean electron temperature

We performed an extended analysis of the northern limb and show that the measured synchrotron cutoff energy is not well constrained in the presence of a shocked ISM component. Such results cannot currently be further investigated by analyzing emission lines in the 0.5–1 keV range, because of the low Chandra spectral resolution in this band. We show with simulated spectra that Athena X-ray Integral Field Unit future performances will be crucial to address this point.

The linear polarization of thermal dust emission provides a powerful tool to probe interstellar and circumstellar magnetic fields, because aspherical grains tend to align themselves with magnetic field lines. While the Radiative Alignment Torque (RAT) mechanism provides a theoretical framework for this phenomenon, some aspects of this alignment mechanism still need to be quantitatively tested. One such aspect is the possibility that the reference alignment direction changes from the magnetic field (“B-RAT”) to the radiation field k-vector (“k-RAT”) in areas of strong radiation fields. We investigate this transition toward the Orion Bar PDR, using multiwavelength SOFIA HAWC+ dust polarization observations. The polarization angle maps show that the radiation field direction is on average not the preferred grain alignment axis. We constrain the grain sizes for which the transition from B-RAT to k-RAT occurs in the Orion Bar (grains ≥ 0.1 μm toward the most irradiated locations), and explore the radiatively driven rotational disruption that may take place in the high-radiation environment of the Bar for large grains. While the grains susceptible to rotational disruption should be in suprathermal rotation and aligned with the magnetic field, k-RAT aligned grains would rotate at thermal velocities. We find that the grain size at which the alignment shifts from B-RAT to k-RAT corresponds to grains too large to survive the rotational disruption. Therefore, we expect a large fraction of grains to be aligned at suprathermal rotation with the magnetic field, and to potentially be subject to rotational disruption, depending on their tensile strength.

A checklist of Orchidaceae from Caquetá, Colombia is presented here. We recorded 98 genera and 418 species, exceeding a previous inventory by 276 species. The checklist is conservative in the number of genera and species by including only taxa that were fully and reliably identified and that are either linked to a corresponding herbarium voucher, a living collection specimen or a photo taken in the field and published in iNaturalist by one of the authors or a collaborator. The documented species diversity in the region could dramatically increase in the next few years with additional collecting efforts in the eastern slopes of the Andes nested in Caquetá. About 9% (418/4600) of all Orchidaceae species recorded for Colombia are reported for this area, showing the important contribution to orchid diversity of Andean-Amazonian foothills of Caquetá.

Published: July 2023

A nonlinear partial differential equation (PDE) based compartmental model of COVID-19 provides a continuous trace of infection over space and time. Finer resolutions in the spatial discretization, the inclusion of additional model compartments and model stratifications based on clinically relevant categories contribute to an increase in the number of unknowns to the order of millions. We adopt a parallel scalable solver that permits faster solutions for these high fidelity models. The solver combines domain decomposition and algebraic multigrid preconditioners at multiple levels to achieve the desired strong and weak scalabilities. As a numerical illustration of this general methodology, a five-compartment susceptible-exposed-infected-recovered-deceased (SEIRD) model of COVID-19 is used to demonstrate the scalability and effectiveness of the proposed solver for a large geographical domain (Southern Ontario). It is possible to predict the infections for a period of three months for a system size of 186 million (using 3200 processes) within 12 hours saving months of computational effort needed for the conventional solvers.

Authors: Kersánszki Tamás , Holik Ildikó , Márton Zoltán
Published: July 2023

In today’s Public Education Sector, the need for creative education is becoming more and more prominent. An excellent method for achieving this is gamification, which provides an opportunity to activate and motivate students by playfully processing the desired knowledge material. Minecraft is a multi-platform video game that can be successfully used in gamified education. This game platform is used at one of the summer camps we announced for elementary and high school students (10–16 years old). The participants mastered the topics of renewable energy sources with the help of the Minecraft game. This study describes the methods used in the camp and presents the research results on the effectiveness of the camp. The students’ current level of knowledge was examined with a questionnaire about renewable energy sources, and the collaborative skills questionnaire was used to assess the collaboration characteristics, and the school creative climate questionnaire was used to explore specific features of the camp. The practical results of the camp and the research results proved that gamification, the use of Minecraft, was excellent for arousing students’ interest, increasing their motivation, and helping them master the knowledge materials, effective task solving, and cooperation (i.e., the camp was equally effective from the point of view of knowledge acquisition and collaboration).

Published: July 2023

The virtual laboratory learning environment on metaverse, or VLLE on metaverse, is a kind of learning media in the virtual world, which can be accessed through a virtual laboratory in the form of metaverse. To enter VLLE on metaverse, users must simulate themselves in the form of 3D avatar, and then they are able to perform any tasks and interact with any objects or surrounding environments therein, which are all virtual images. The study question of this research focuses on the steps and methods related to the development of media for use in VLLE on metaverse and on what design features are satisfactory and would be well accepted by participants. In this study, the researchers have applied concepts and new teaching innovations that correspond to the current situations and can support the learning formats that can be done anywhere and anytime. This practice is believed to promote self-directed learning experiences and other skills while allowing students to evaluate their activities on their own as well. The research results are in line with the researchers’ expectations: it was found that VLLE on metaverse can be used as a public interaction tool through mobile applications for the university population and the general public outside. This is because new technologies have been developed and employed in the media and the existing technologies in such a way that an environment close to the real learning conditions can be produced, which can create a learning society without borders.

Published: July 2023

Many studies in engineering education believe that higher-order thinking skills (HOTs) are a fundamental competency for engineering students. Polymer engineering students study and analyze the character and structure of polymer materials and use that knowledge to design innovative new products. However, students might need more applied contexts to creativity and learning motivation in polymer material instruction. This paper is a study to present new-product creativity (NPC) through the engineering design process (EDP) for polymer engineering students. The quasi-experimental design was implemented in the learning activity of the polymer-processing laboratory course. A total of 21 participants were recruited from two groups of students (10 were in the experimental group, and 11 were in the control group) at a university in Thailand. The experimental results showed that the students who learned with NPC-EDP had better HOTs in the polymer-processing laboratory course than those who learned with conventional learning. In addition, the students also showed that they were motivated to learn meaningfully in engineering education.

Published: July 2023

At the onset of an infectious disease, such as the monkeypox virus (MPXV), surveillance data is crucial in keeping track of the outbreak’s progression. The surveillance data for MPXV received considerable attention after multiple European countries recorded cases. Historical data obtained from May 9, 2022, to August 10, 2022, were used to model the cumulative case trajectories of MPXV in five countries. Our study employed autoregressive integrated moving averages (ARIMA), neural network autoregression (NNETAR), exponential smoothing (ETS), and seasonal naïve regression (SNAÏVE) for training and evaluation. The paper makes the following contributions: (1) enhanced model stability with the Box-Cox transformation as a preprocessing step, (2) experimentation with both linear and non-linear models, and (3) simulation of the top five countries during the impulsive rise in cases of MPXV. The results were evaluated using three metrics: root mean square error (RMSE), mean square error (MAE), and mean absolute percentage error (MAPE). The ARIMA (0,1,3) (1,0,0)[7] model yielded the lowest percentage error of 5.16 in the holdout set for MAPE in France observations. The ETS (A, A, A) model, the lowest percentage error in the holdout set for MAE was 7.35 in Germany. Regarding the NNETAR (1,1,2) [7] model, the lowest percentage error in the holdout observations for RMSE was 8.33 in Spain, 2.75 in the United Kingdom (UK), and 8.05 in the United States of America (USA) in that order. Based on these findings, we can conclude that while the transformation proved crucial for model performance, it was not necessary for all experiments, as ARIMA remained dominant in France and the ETS model in Germany. At the same time, NNETAR model outperformed in cumulative case counts in Spain, the UK, and the USA. Our experimentation allows for early identification and contributes to a better understanding of forecasting MPXV cases using combinations of both linear and nonlinear models.
El Conservador (1820), un periódico exaltado del Trienio Liberal para justificar la abrogación de la Inquisición y servir a la Historia
Authors: Cavaillon Giomi Joan
Published: July 2023

A pesar de su título, El Conservador, periódico editado en Madrid del 27 de marzo al 30 de septiembre de 1820, no tenía nada de «conservador». Ferviente opositor a la Inquisición, demostró la sensatez de su abrogación publicando varios artículos que denunciaban sus abusos y las atrocidades perpetradas por sus miembros entre 1814 y 1820, un periodo durante el que el Tribunal del Santo Oficio fue, según el periódico, más represivo que por el pasado y por el que no había cifras ni testimonios. El Conservador exhortó también a los reos que salieron de las cárceles secretas a testimoniar para servir a la Historia. Así, analizando los artículos publicados sobre la Inquisición y sus miembros, este artículo, tras la presentación de un periódico poco estudiado, intenta dar a conocer las actividades del Santo Oficio en una época por la que carecemos de datos.
Accuracy of Death Certification of Cause of Death in Home Deaths by Grama Niladhari in Selected Divisional Secretariat Areas of Sri Lanka
Authors: Appuhamy P. , Samaranayaka R. , Manjika S.
Published: July 2023

Introduction: Accurate and complete medical data on the cause of death are critically important for designing and evaluating health programs and policies. Mortality medical data on deaths that occur inside a healthcare facility are certified by medical officers and therefore they are considered to be reliable and accurate. However, approximately one-half of the 130,000 deaths which occur each year in Sri Lanka take place outside a healthcare facility. There are several death certification systems existing for getting a death registered after determining the cause of death and obtaining the death certificate in home deaths in Sri Lanka without the involvement of a medical officer. Those systems involve either Inquire into Sudden Death, Grama Niladhari, Police Officer, or Estate Superintendent as the individual responsible for stating the cause of death. Few studies have analysed the causes of death stated by the ISD however, there are no published studies that have analysed the cause of death stated by Grama Niladharies on home deaths in Sri Lanka.Methods: This retrospective cross-sectional descriptive study was carried out on home deaths that occurred between September 2021 and September 2022 in the Matale and Ukuwela divisional secretariat areas of Sri Lanka using secondary data collected from B 24 forms which were filled by Grama Niladhari of respective divisions.Results: The study included 230 home deaths. 72% of medical records were of poor quality to assign a cause of death. In all these death certificates, the cause of death was not stated according to the WHO format of the cause of death. Fifty-four percent used an ill-defined condition as the underlying cause of death. Cancer was the cause of death in 11% of adults and accounted for the highest number of cases.Conclusions: Grama Niladhari in Sri Lanka has difficulties in completing the cause of death accurately. They routinely made errors in death certification because of these inaccurate causes of death. This situation needs rectifiable measures as home death data is very vital for certain healthcare decisions.

Published: July 2023

We report a case of a 20-day-old female child who was full-term born by emergency Caesarean section due to foetal distress. The baby had intermittent dyspnoea and was pronounced dead with unsuccessful resuscitation efforts in her admission to the hospital. Post-mortem examinations revealed dilated cardiomyopathy with endocardial fibroelastosis. Histologic examination of the heart showed mild endocardial fibroelastosis and sub-endocardial and interstitial increased elastin and collagen fibre deposition. Molecular testing was heterozygous for ELAC2 (pathogenic) and PRDM16 (variant of uncertain significance [VUS] genes. Other ancillary test results are non-contributory. Based on the autopsy findings, ancillary test results, and clinicopathological correlation, the cause of death is neonatal dilated cardiomyopathy (DCM).

The brain-type natriuretic peptides (BNP) and troponins levels can be used for the risk stratification of patients presenting with acute myocardial infarctions. Elevated levels of N-terminal pro-brain natriuretic peptide (NT-ProBNP) can be seen in patients with heart failure (HF) and atrial fibrillation.

Objectives:

The aim is to evaluate the NT-ProBNP levels and high-sensitive troponin-T (Trop T-HS) levels in patients with ischemic and nonischemic HF and to analyze its association with prognosis.

Methods:

This prospective observational study was conducted in a tertiary Centre over a period of 2 years. We analyzed NT-ProBNP and Trop T-HS levels of patients with HF, who were admitted to our cardiac intensive care unit. Patients with acute coronary syndrome, myocarditis, and renal failure were excluded from the study. The study population consists of 130 patients, of which 90 patients with ischemic dilated cardiomyopathy (ISDCM) and 40 patients with idiopathic dilated cardiomyopathy (IDCM). They belonged to the New York Heart Association functional classes 3 and 4. The diagnosis was made with the help of a coronary angiogram and transthoracic echocardiogram. We analyzed the NT-ProBNP levels and Trop T-HS of both groups of patients.

Results:

Males were predominant in both groups, i.e., 70 (77.8%) in the ISDCM patients and 26 (65%) in the IDCM patients. The NT-ProBNP levels were significantly higher among patients with ISDCM compared to patients with (IDCM) dilated cardiomyopathy (8648 ± 6207 pg/mL vs. 3100 ± 2906 pg/mL); P = 0.0008. We analyzed the NT-ProBNP levels of the survivors and nonsurvivors in each group separately. We found that there were significant differences in the levels of NT-ProBNP in the survivors and nonsurvivors in the ISDCM group (7061 ± 3663 vs. 18035 ± 4667 pg/mL); P = 0.0004. However, there was no significant difference between the survivors and nonsurvivors of IDCM patients (4701 ± 737 vs. 6821 ± 1212 pg/mL); P = 0.07. Like the previous analysis, higher levels of Trop T-HS levels were found in patients with ISDCM group compared with IDCM group (26.6 ± 8.5 ng/L vs. 16.3 ± 3.4 ng/L); P = 0.0002. There was also a significant raise of Trop T-HS in the nonsurvivors in the ISDCM group compared to the survivors (28.9 ± 16.3 vs. 65.5 ± 17.0 ng/L): P = 0.0003. Conclusion: In this study, we found that HF patients who were admitted with higher levels of NT-ProBNP and Trop T-HS had a poor prognosis.

Diabetic foot is a common complication of diabetes and leads to considerable morbidity and mortality. Neuropathy, deformity, infection and ischemia play a key role in the pathogenesis of diabetic foot ulcer. A multidisciplinary team approach by a nurse, physician, diabetic foot surgeon and the caregiver as well as close monitoring can prevent foot complications. Proper foot care, foot hygiene, annual foot examination and correct choice of footwear are main factors in preventing foot problems, ulceration and amputations. Physicians play a lead role in early detection and prevention of foot problems. This article will focus on how to perform foot examination in routine clinical practice.

Type 2 diabetes mellitus (T2DM) has become a worldwide epidemic, especially in Asian countries as a result of rapid socioeconomic development, overnutrition, and lack of physical activity. Among the strategies for preventing and managing T2DM, the promotion of healthy dietary habits plays an important role. Various studies which were mainly carried out in Western countries showed that higher dietary fiber (DF) intake has a significant association with a lower risk of the development of T2DM. Thus, a narrative review concentrating on the macronutrient DF was performed. PubMed and Google Scholar were used for this purpose. The goal was to examine the most recent medical research on the advantages of DF for health, with a particular emphasis on how DF consumption affects glycemic management.

Post-traumatic stress disorder (PTSD) is a serious psychiatric disorder, and there is an association between it and the development of cardiovascular disease. The aim of this study was to explore whether there is a glutamatergic pathway connecting the medial habenula (MHb) with the rostral ventrolateral medulla (RVLM) that is involved in the regulation of cardiovascular function in a rat model of PTSD. Vesicular glutamate transporter 2 (VGLUT2)-positive neurons in the MHb region were retrogradely labeled with FluoroGold (FG) by the double-labeling technique of VGLUT2 immunofluorescence and FG retrograde tracing. Rats belonging to the PTSD model group were microinjected with artificial cerebrospinal fluid (ACSF) or kynurenic acid (KYN; a nonselective glutamate receptor blocker) into their RVLM. Subsequently, with electrical stimulation of MHb, the discharge frequency of the RVLM neurons, heart rate, and blood pressure were found to be significantly increased after microinjection of ACSF using an in vivo multichannel synchronous recording technology; however, this effect was inhibited by injection of KYN. The expression of N-methyl-D-aspartic acid (NMDA) and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor subunits was significantly increased in RVLM of PTSD model rats analyzed by the Western blotting technique. These findings suggest that there may be a glutamatergic pathway connection between MHb and RVLM and that this pathway may be involved in the regulation of cardiovascular function in the PTSD model rats, by acting on NMDA and AMPA receptors in the RVLM.

Published: July 2023

Introduction:

An impacted tooth is one that remains unerupted and/or is partly erupted due to mechanical obstructions. These teeth can give rise to a magnitude ranging from dental caries, tumors, periodontal diseases to even jaw fractures.

Materials and Methods:

The study aimed to identify and analyze the impaction of maxillary and mandibular canines, premolars, and molars among children and adolescents aged 13 to ≤21 years of Indian origin belonging to both sexes who reported orthodontic treatment having good quality radiographs and medical/dental case sheets. The Pearson’s Chi-square test analyzed the data obtained. Level of with a significance was set at P < 0.05.

Results:

Of 1001 individuals (551 M, 450 F), we could detect 709 individuals with impaction. The prevalence of impaction of third molar, canine, and premolar was found to be 29.1%, 31.4%, and 10.3%, respectively. Molar and canine impactions were more common in males, while premolar impactions were observed more in females.

Conclusion:

The prevalence of third molar impaction, canine impaction, and premolar impaction was found to be 29.1%, 31.4%, and 10.3%, respectively. Molar and canine impactions were more common in males, while premolar impactions were observed more in females among the patients reported for orthodontic treatment.

Generic medicine is a pharmaceutical drug which contains the same active ingredients as a branded drug in terms of strength, dosage, route of administration, quality, safety, performance characteristics, and therapeutic use. Generic medicine plays a major role in providing affordable medicines to patients. This systematic review was done to identify the knowledge regarding generic medicine prescription among dental and medical professionals worldwide. The search was performed in four databases PubMed, Turning Research Into Practice database (Trip database), Cochrane Library, and Google Scholar to identify the relevant articles with specific keywords and the time filter was February 2012 to February 2022. Finally we included 11 cross-sectional studies. However, generic prescribing is not very much adopted in India due to a lack of awareness about regulatory standards used in generic drug manufacturing. Based on this, the systematic review found that limited knowledge and negative perception among medical and dental professionals about generic medicine are clearly a major barrier to the implementation of generic medicine.

Sentiment analysis is a person's opinion or view of a particular object that produces positive, negative, or neutral sentiments. The government's effort during the COVID-19 pandemic is to call for the implementation of a booster vaccination program to the public. Based on this, it produces several public sentiments, some of which are uploaded on the Twitter social media platform, which generate positive and negative sentiments. To find out the classification of public sentiment, the researchers carried out calculations using the K-Nearest Neighbor and Naïve Bayes Classifier methods. Based on the calculation results, it was found that the public sentiment was positive at 98% and negative at 2%. This means that the community is enthusiastic and supports the booster vaccination program. Then the comparison based on the calculation results, namely the K-Nearest Neighbor method with a K value of 3 resulting in an accuracy calculation of 97.33% and using the Naïve Bayes Classifier method, an accuracy calculation of 97.35% can be generated. So it can be seen that using the Naïve Bayes Classifier method has a higher accuracy than the K-Nearest Neighbor method.
