Line Follower Robot

International Journal of Advanced Research in Science, Communication and Technology
In the realm of autonomous robotics, line following robots represent an essential stepping stone toward advanced automated systems. This paper introduces a smart line follower robot enhanced with adaptive path correction using ultrasonic sensors. Unlike traditional line followers that rely solely on infrared (IR) sensors for navigation, our approach ...

Linear scleroderma following Blaschko′s lines

Indian Journal of Dermatology, Venereology and Leprology, 2005
Blaschko's lines form a pattern, which many diseases are found to follow, but linear scleroderma following Blaschko's lines is a controversial entity rarely reported in the literature. A 24-year-old man presented with multiple linear, atrophic, hyperpigmented lesions punctuated by areas of depigmentations on the left half of the trunk distributed on ...

Theory of the vortex matter transformations in high Tc superconductor YBCO

, 2003
Flux line lattice in type II superconductors undergoes a transition into a "disordered" phase like vortex liquid or vortex glass, due to thermal fluctuations and random quenched disorder.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

2D-STRAIGHT LINE PATH FOLLOWING AND NUMERICAL SIMULATION

Havacılık ve Uzay Teknolojileri Dergisi, 2018
In this paper, a two-dimensional-straight-line path following methodology for an unmanned aircraft is developed. With the developed algorithm, the unmanned aerial vehicle is made to converge to a predefined path, and then to follow a virtual target on ...

Eliashberg's proof of Cerf's theorem

, 2010
Following a line of reasoning suggested by Eliashberg, we prove Cerf's theorem that any diffeomorphism of the 3-sphere extends over the 4-ball. To this end we develop a moduli-theoretic version of Eliashberg's filling-with-holomorphic-discs method ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
