AbstractWe built a novel setup to record large gaze shifts (up to 140$$^\circ $$

∘

). The setup consists of a wearable eye tracker and a high-speed camera with fiducial marker technology to track the head. We tested our setup by replicating findings from the classic eye–head gaze shift literature. We conclude that our new inexpensive setup is good enough to investigate the dynamics of large eye–head gaze shifts. This novel setup could be used for future research on large eye–head gaze shifts, but also for research on gaze during e.g., human interaction. We further discuss reference frames and terminology in head-free eye tracking. Despite a transition from head-fixed eye tracking to head-free gaze tracking, researchers still use head-fixed eye movement terminology when discussing world-fixed gaze phenomena. We propose to use more specific terminology for world-fixed phenomena, including gaze fixation, gaze pursuit, and gaze saccade.

In this very advanced era of globalization, the use of technology has become commonplace for society, one of which is using technology in the buying and selling process. One of them is UMKM actors in Pasirbaru Village, Cisolok sub-district, Sukabumi district. With modern empowerment that focuses on UMKM’s, it is hoped that UMKM actors in Pasirbaru Village can utilize technology as a means to develop their businesses. There are several actors in Pasirbaru Village who still promote their business traditionally. The selling market is not extensive and there is no distinctive feature of their products. Therefore, knowledge and training are needed so that players will be ready for facing global market and improve the quality of their products and increase their production capacity. The aim is to find out to what extent the Pasirbaru village community optimizes current technology as a means of transportation, communication and marketing media, then so that the community can be independent so that the latest innovations will emerge that can improve the community's standard of living. This research uses a survey method which is still a quantitative method. This research basically involves UMKM players in telling the situation and development of their business from the past to the present, by conducting observations and interviews to collect data which will later be processed to produce results or solutions. The goal is that UMKM players can take advantage of current technology to brand their products and market their products through online media. The importance of technology to help with daily life is no surprise that most people nowadays definitely use technology, because currently technology is something that can no longer be avoided. Starting from transportation technology, communication, information and others.

Published: January 2024

Objective: Cancers are currently adjudged as a hindrance to achieving a desirable life expectancy in most countries. The high mortality rate from ovarian cancer is a result of the pathology not having specific symptoms, late presentation, and lack of proper screening that results in its diagnosis in the advanced stages. The study aimed to determine the prevalence, clinical presentation, and outcome after the management of patients with ovarian cancer seen in the tertiary institution.
Methodology: It was a retrospective study. Relevant information was extracted from the case files of the patients with histologically confirmed ovarian cancer. The data obtained were analysed using Statistical Package for Social Sciences (SPSS) statistical software, version 23.
Results: Thirty-two cases of ovarian cancer were admitted during the period under review. This constituted 21.0% of gynaecological malignancies managed in the hospital during the study. The mean age of the ovarian cancer patients was 50.94±12.01 years with 56.25% of the patients being postmenopausal. The majority of the patients (62.4%) have 3 or more parous experiences with 53.1% of the patients presenting with advanced disease. Epithelial ovarian cancer was the most common histological variant. The treatment modality was surgery and chemotherapy. However, 65.7% of patients defaulted from initiating or completing chemotherapy.
Conclusion: The study revealed that patients presented in the late stage of the disease and a bulk of them did not complete the treatment. There is a need to lobby Governments to subsidize cancer treatment, especially in the area of chemotherapy treatment.

Abstract
Mass loss is a crucial process that affects the observational properties, evolution path, and fate of highly evolved stars. However, the mechanism of mass loss is still unclear, and the mass-loss rate (MLR) of red supergiant stars (RSGs) requires further research and precise evaluation. To address this, we utilized an updated and complete sample of RSGs in the Large Magellanic Cloud (LMC) and employed the 2-DUST radiation transfer model and spectral energy distribution fitting approach to determine the dust-production rates (DPRs) and dust properties of the RSGs. We have fitted 4714 selected RSGs with over 100,000 theoretical templates of evolved stars. Our results show that the DPR range of RSGs in the LMC is 10−11

The optically thin RSG, which comprise 30.6% of our sample, contribute only 0.1% of the total DPR, while carbon-rich RSGs (6.1%) produce 2.7% of the total DPR. Overall, 208 RSGs contributed 76.6% of the total DPR. We have established a new relationship between the MLR and luminosity of RSGs in the LMC, which exhibits a positive trend and a clear turning point at

Published: January 2024

Abstract
We present 500 and 700 au resolution 1 and 3 mm Atacama Large Millimeter/submillimeter Array observations, respectively, of protostellar cores in protoclusters Sagittarius B2 (Sgr B2) North (N) and Main (M), parts of the most actively star-forming cloud in our Galaxy. Previous lower-resolution (5000 au) 3 mm observations of this region detected ∼150 sources inferred to be young stellar objects (YSOs) with M > 8 M
⊙. With a 10-fold increase in resolution, we detect 371 sources at 3 mm and 218 sources in the smaller field of view at 1 mm. The sources seen at low resolution are observed to fragment into an average of two objects. About one-third of the observed sources fragment. Most of the sources we report are marginally resolved and are at least partially optically thick. We determine that the observed sources are most consistent with Stage 0/I YSOs, i.e., rotationally supported disks with an active protostar and an envelope, that are warmer than those observed in the solar neighborhood. We report source-counting-based inferred stellar mass and the star formation rate of the cloud: 2800 M

How Can the Optical Variation Properties of Active Galactic Nuclei Be Unbiasedly Measured?
Authors: Hu Xu-Fan , Cai Zhen-Yi , Wang Jun-Xian 
Published: January 2024

Abstract
The variability of active galactic nuclei (AGNs) is ubiquitous, but has not yet been understood. Measuring the optical variation properties of AGNs, such as the variation timescale and amplitude, and then correlating them with their fundamental physical parameters has long served as a critical way of exploring the origin of AGN variability and the associated physics of the accretion process in AGNs. Obtaining accurate variation properties of AGNs is thus essential. It has been found that the damped random walk process can describe the AGN optical variation well, but there is a controversy over how long a minimal monitoring baseline is required to obtain unbiased variation properties. In this work, we settle the controversy by exhaustively scrutinizing the complex combination of assumed priors, adopted best-fit values, ensemble averaging methods, and fitting methods. The new proposal is then an optimized solution where unbiased variation properties of an AGN sample possessing the same variation timescale can be obtained with a minimal baseline of about 10 times their variation timescale. Finally, the new optimized solution is used to demonstrate the positive role of the time-domain surveys to be conducted by the Wide Field Survey Telescope in improving constraints on AGN variation properties.
Primordial Black Hole Merger Rate in f(R) Gravity
Authors: Fakhry Saeed 
Published: January 2024

Abstract
Primordial black holes (PBHs) are known as one of the potential candidates for dark matter. They are expected to have formed due to the direct gravitational collapse of density fluctuations in the early Universe. In this regard, examining the merger rate of PBHs within modified theories of gravity can offer a deeper insight into their abundance. In this work, we delve into the calculation of the merger rate of PBHs within the theoretical framework of f(R) gravity. Our analysis reveals an enhancement in the merger rate of PBHs compared to that obtained from general relativity. Additionally, modulating the field strength f
R0 induces shifts in the PBH merger rate, presenting a potential observational signature of modified gravity. We also explore the upper bounds on the abundance of PBHs obtained from f(R) gravity models by comparing the results with gravitational-wave and observational data. The results indicate that in certain regions not excluded by benchmarking data, the parameter space for these upper bounds may be considered reliable.

Published: January 2024

ABSTRACT

Introduction:
Head-and-neck lesions are common and varied, ranging from inflammatory conditions to malignancies. Fine-needle aspiration cytology (FNAC) is a crucial diagnostic technique, and ultrasound-guided FNAC (UG-FNAC) has become increasingly important for accurate diagnosis. The purpose of this study was to assess the effectiveness of UG-FNAC for the management of head-and-neck lesions.

Subjects and Methods:
A hospital-based cross-sectional study was conducted from December 2021 to January 2023, involving 119 patients with head-and-neck lesions. UG-FNAC was performed, and clinical history, ultrasound findings, and histopathological correlation were recorded. Statistical analysis was carried out using SPSS version 26.

Results:
The study included 119 cases, predominantly in patients below 50 years of age. The most common aspirates were from lymph nodes (52.94%), followed by thyroid (22.68%) and salivary gland (16.8%) lesions. We found that the cytological and histological diagnoses were consistent in the majority of cases, with sensitivity, specificity, and accuracy rates of 85.71%, 100%, and 91.6%, respectively.

Discussion:
UG-FNAC has proven to be a valuable tool in the diagnosis of head-and-neck lesions, allowing for accurate targeting of nonpalpable lesions and improved patient management. The cytological and histological correlation rates observed in this study are consistent with previous studies, indicating the reliability of the technique.

Conclusion:
UG-FNAC is a reliable and accurate diagnostic technique for head-and-neck lesions. It facilitates preoperative preparation, patient consent, and appropriate surgical treatment. The high diagnostic accuracy and minimal complications associated with this procedure make it an important tool in the management of superficial and deep-seated head-and-neck lesions.

ABSTRACT

Introduction:
Millions of babies are admitted to neonatal intensive care units (ICUs) worldwide, with a significant proportion facing various indications. Given that sepsis is a leading cause of mortality and morbidity among infants globally, including in India, the importance of efficient antibiotic use cannot be overstated. As the global problem of drug resistance intensifies, prudent antibiotic usage becomes crucial in mitigating treatment failures and ensuring the survival of newborns.

Aim:
The aim of this study was to evaluate the pattern of antimicrobial drug utilization in neonatal intensive care unit (NICU) to assess the criteria for drug selection in a tertiary care hospital.

Materials and Methods:
It was an observational, prospective study conducted for 6 months in which 200 neonates admitted to the NICU at a tertiary care hospital were included in the study.

Results:
Out of 200 neonates, the number of male babies admitted to NICU was 115 (57.5%) and female babies were 85 (42.5%). Many of the neonates were from the age group of 1 to 5 days (58.5%). Most of the neonates were from the weight group of 2.5 to 3 kg (26.5%). The hospital admission duration for the majority of neonates is within the 3–6-day range, accounting for 98 neonates, which represents 49% of the cases. The most prevalent reason for admission to the neonatal ICU (NICU) was preterm with respiratory distress syndrome, comprising 29% of cases, followed by neonatal sepsis at 19.5%, and preterm births at 11%. Among 423 antibiotics, the most prescribed antibiotic was injection piperacillin + tazobactam (35.4%) followed by gentamicin (30.2%).

Conclusion:
Empirical antibiotics were administered to every newborn based on their individual conditions. The antibiotic utilization pattern within this study group was determined to be rational.

ABSTRACT

Background:
In this ever-evolving present era, the field of medicine is also changing and innovating at an unmatchable pace. The implication of nanotechnology in medicine is the need of the hour to serve the human health-care sector and to make this world a better place to live. In this era, humans are suffering from immense mortality because of many life-threatening diseases. Cardiovascular complications are among one of the major reasons for morbidity and mortality, such as angina pectoris.

Aims and Objective:
Furthermore, in the past few decades, polysaccharides such as chitosan have gained great attention to be used as a carrier system in nanomedicine due to their favorable properties. Materials with a nanoscale structure, or nanocomposites, are used to enhance products’ macroscopic characteristics. A rapidly expanding field of study is nanocomposite organic/inorganic materials in general. The ability to achieve control of the nanoscale structures via novel synthetic techniques is the subject of intense research.

Material and Method:
Intending to formulate a sustained release nanocarrier system of an antianginal agent, i.e., nicorandil, this study has implied a widely acceptable and feasible technique of ionic gelation. This technique implies sodium tripolyphosphate having a negative charge while the cationic character of chitosan, hence resulting in the formation of a nanoscale drug carrier vehicle. Then, formulated nanocomposites were characterized by several widely accepted methods such as zeta size and potential, powder X-ray diffraction, scanning electron microscopy, FTIR, and differential scanning calorimetry and thermogravimetric analysis.

Results:
The mean diameter of the resulting formulation is also in the favorable range (278 nm). The formulation showed significant incorporation of active drugs inside the carrier system. Loading of drug and entrapment efficiency results were promising, while the drug release profile showed sustained drug release patterns from the vehicle.

Conclusion:
Thus, the present study presents the potential to overcome limitations such as low bioavailability, side effects, and poor stability of the medicinal agent used.

Published: January 2024

ABSTRACT

Context:
The persistence of respiratory symptoms beyond 4 weeks otherwise known as postacute COVID-19 symptoms has been reported to significantly affect the clinical outcome, quality of life (QOL), and well-being of patients’ postinfection.

Aims:
The study aims to determine the pattern of postacute COVID-19 dyspnea symptoms, QOL, and well-being and its association at month 1 and 6 following COVID-19 infection.

Settings and Design:
A prospective cohort study of two COVID-19 hospitals in Malaysia was conducted.

Subjects and Methods:
Patients were followed up from admission, discharge, and 6 months after. A standard questionnaire assessed demographics, Modified Medical Research Council (mMRC) dyspnea score, QOL EQ-5D-5L scale (mobility, ability to self-care, ability to perform usual activity, pain, and anxiety), and the World Health Organization (WHO)-5 well-being index.

Statistical Analysis Used:
Wilcoxon signed-rank, Kruskal–Wallis, and Pearson correlation tests were used.

Results:
The mMRC, ED-5D-5L, and WHO-5 scores worsened during admission and slowly resolved over the 6 months (n = 388). mMRC scores positively correlated with EQ-5D-5L scores for mobility, self-care, ability to perform usual activity, pain, and anxiety (visit 1 and 6, P = 0.00) during the 1st and 6th months. Higher mMRC and EQ-5D-5L scores indicate worsening dyspnea and QOL. mMRC demonstrated a negative correlation with WHO-5 scores (visit 1: r = −0.30 and visit 6: r = −0.39, P = 0.00), which indicated worsening dyspnea and lower mental well-being. A higher WHO-5 well-being index was associated with lower EQ-5D-5L scores (visit 1 and 6, P = 0.00), demonstrating lowered patient’s well-being with worsening QOL.

Conclusions:
As such, appropriate health-care support and monitoring of patients, postdischarge is essential to optimize patient outcome.
