A distributed control strategy for groups of robots with application in flocking.

This paper presents a distributed control strategy, named Triangle Formation (TF) algorithm, for a group of robots. The algorithm is based on a geometric approach and enables three neighboring robots to form an Equilateral Triangular Configuration (ETC). The TF algorithm is scalable since it is developed for a large group of robots by using a neighbor selection technique.

Genetic architecture of Multiple Myeloma and its prognostic implications - An updated review.

Multiple myeloma (MM), a clonal B-cell neoplasia, is an incurable and heterogeneous disease where survival ranges from a few months to more than 10 years. The clinical heterogeneity of MM arises from multiple genomic events that result in tumour development and progression. Recurring genomic abnormalities including cytogenetic abnormalities, gene mutations and abnormal gene expression profiles in myeloma cells have a strong prognostic power.

Coronavirus disease 2019 (COVID-19) has been a global pandemic affecting millions of people's lives, which has led to 'post-COVID-19 fatigue'. Alarmingly, severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) not only infects the lungs but also influences the heart and brain. Endothelial cell dysfunction and hypercoagulation, which we know occur with this infection, lead to thrombo-inflammation that can manifest as many myriad cardio-cerebrovascular disorders, such as brain fog, fatigue, cognitive dysfunction, etc.

Violaceoid F induces nuclear translocation of FOXO3a by inhibiting CRM1 via a novel mechanism and suppresses HeLa cell growth.

FOXO3a is a transcription factor involved in cell growth inhibition and apoptosis. FOXO3a is localized in the cytoplasm in cancer cells, and its nuclear translocation by small molecules is expected to prevent cancer cell growth. In this study, we screened a fungal broth library in HeLa cells using fluorescently labeled FOXO3a and an AI-based imaging system.

Perceptions and perspectives towards safe food handling and its practices: a case study at Jahangirnagar University.

Background: Foodborne illness is a significant public health concern, particularly in developing countries like Bangladesh. Young adults, aged 18-26 (including undergraduates and recent graduates), are especially vulnerable to the onset of unhealthy eating habits and nutritional imbalances as they begin living independently, often away from their families. This research aims to identify the risk factors associated with the knowledge, attitudes, and practices related to safe food handling among residential university students.

In silico selection against progesterone receptor DNA-binding domain.

Development and structural comparison of alkaline and organosolv coconut husks lignin as an eco-friendly lignin-phenol-glyoxal (LPG) wood adhesives.

The development of eco-friendly wood adhesives have gained more interest among adhesives industries due to the concerns about using carcinogenic formaldehyde and petroleum-based phenol in commercially available adhesives. Therefore, many studies have been done by using lignin to partially replace phenol and completely substitute formaldehyde with non-toxic glyoxal in a wood adhesive formulation. This study focused on using different percentages of lignin substitution (10 %, 30 % and 50 wt%) of alkaline and organosolv coconut husk lignin into soda lignin-phenol-glyoxal (SLPG), Kraft lignin-phenol-glyoxal (KLPG) and organosolv lignin-phenol-glyoxal (OLPG) adhesives.
