Isomorphisms of semigroups of transformations

If M is a centered operand over a semigroup S, the suboperands of M containing zero are characterized in terms of S-homomorphisms of M. Some properties of centered operands over a semigroup with zero are studied

Which Experimental Design is Better Suited for VQA Tasks? Eye Tracking Study on Cognitive Load, Performance, and Gaze Allocations

We conducted an eye-tracking user study with 13 participants to investigate the influence of stimulus-question ordering and question modality on participants using visual question-answering (VQA) tasks. We examined cognitive load, task performance, and gaze allocations across five distinct experimental designs, aiming to identify setups that minimize the cognitive burden on participants. The collected performance and gaze data were analyzed using quantitative and qualitative methods. Our results indicate a significant impact of stimulus-question ordering on cognitive load and task performance, as well as a noteworthy effect of question modality on task performance. These findings offer insights for the experimental design of controlled user studies in visualization research.Comment: Accepted at ETVIS 202

Amplification-free detection of circulating microRNA biomarkers from body fluids based on fluorogenic oligonucleotide-templated reaction between engineered peptide nucleic acid probes: application to prostate cancer diagnosis

Highly abundant in cells, microRNAs (or miRs) play a key role as regulators of gene expression. A proportion of them are also detectable in biofluids making them ideal noninvasive biomarkers for pathologies in which miR levels are aberrantly expressed, such as cancer. Peptide nucleic acids (PNAs) are engineered uncharged oligonucleotide analogues capable of hybridizing to complementary nucleic acids with high affinity and high specificity. Herein, novel PNA-based fluorogenic biosensors have been designed and synthesized that target miR biomarkers for prostate cancer (PCa). The sensing strategy is based on oligonucleotide-templated reactions where the only miR of interest serves as a matrix to catalyze an otherwise highly unfavorable fluorogenic reaction. Validated in vitro using synthetic RNAs, these newly developed biosensors were then shown to detect endogenous concentrations of miR in human blood samples without the need for any amplification step and with minimal sample processing. This low-cost, quantitative, and versatile sensing technology has been technically validated using gold-standard RT-qPCR. Compared to RT-qPCR however, this enzyme-free, isothermal blood test is amenable to incorporation into low-cost portable devices and could therefore be suitable for widespread public screening

IJCM_392A: Assessment of the level of Physical activity among school and college going adolescents in the urban field practice area of Guntur Medical College

Background: Inadequate Physical Activity is a common feature running through most public health problems across the world. Physical activity declines during the lifespan, especially during adolescence. Identifying patterns of physical activity behaviour in adolescent population will help to improve interventions for youth to become and stay active into adulthood. Objective: 1. To assess the level of physical activity among school and college going adolescents in the urban field practice area of Guntur Medical College. 2. To identify the factors influencing the level of physical activity. Methodology: This cross-sectional descriptive study was carried out among 300 adolescents (aged 10 to 19 years) attending government schools or junior colleges. One school and one college from the field practice area were selected by simple random sampling whereas students from each class were selected by stratified random sampling. A pre-tested, pre-designed semi-structured questionnaire adapted from the Global Physical Activity Questionnaire (GPAQ) and the Physical Activity Questionnaire- Adolescent (PAQ-A) was used for collecting data on physical activity. Results: 30.3% of the adolescents were practicing low physical activity. Level of physical activity was significantly associated with gender, academic grade, father’s schooling, availability of facilities in the neighbourhood, and availability of facilities at home. Among adolescents who are practicing low physical activity, 76.1% reported lack of time as the barrier. Conclusion: A substantial proportion of the adolescents are practicing low physical activity varying across different factors viz., gender, academic grade, availability of facilities in neighborhood or at home

Evaluation of Manufacturing Process Performance by CONWIP Hybridization of Pull Controlled Production Systems

The main objective of this paper is pioneering an innovative tactic for the synchronization of multi-stage, multi-line, production system. This tactic is mainly depends on the optimization policy, by means of distinct event simulation process for modeling, analysis and distinction of the execution of two alternatives of Kanban control mechanism namely SEKCS (Simultaneous Extended Kanban Control System) and IEKCS (Independent Extended Kanban Control System). At this juncture the authors putting forward the two variants of Extended Kanban control system with the hybridization of CONWIP control policy to incite HSEKCS (Hybrid Simultaneous Extended Kanban Control System) and HIEKCS (Hybrid Independent Extended Kanban Control System) to make use of pooled benefits of a representative production situation in addition to improve the outcome. Therefore in this study the comparison in between different systems of proposed HEKCS specifically are HSEKCS and HIEKCS compared with the Extended Kanban Control Systems variants SEKCS and IEKCS. Simulation studies were conducted for all the five control policies considered and modeled on a multi-line, multi-stage assembly production control system. The relative performance parameters like Throughput or Production rate, Average Waiting Time and Average Work-in-Process, were assessed by means of exponentially varying demands
