Peculiar hyper vascular manifestations in idiopathic multicentric castleman disease without tafro syndrome: a case report.

Background: Castleman disease affects lymph nodes with abnormal cell growth. It has unicentric (single node) Castleman disease (UCD) and multicentric (multiple nodes) Castleman disease (MCD) forms. MCD is systemic, with diverse symptoms, necessitating systemic treatment.

Analysis of gaze patterns during facade inspection to understand inspector sense-making processes.

This work seeks to capture how an expert interacts with a structure during a facade inspection so that more detailed and situationally-aware inspections can be done with autonomous robots in the future. Eye tracking maps where an inspector is looking during a structural inspection, and it recognizes implicit human attention. Experiments were performed on a facade during a damage assessment to analyze key, visually-based features that are important for understanding human-infrastructure interaction during the process.

A Cross-Sectional Survey of Knowledge, Attitude, and Practices of University Students in Pakistan Regarding COVID-19.

The COVID-19 pandemic is striking the world with serious public health and socioeconomic complications. The pandemic has influenced all forms of daily life, including educational institutions. Therefore, this cross-sectional survey was conducted to understand knowledge, attitudes, and practices related to COVID-19 among the students of the University of Veterinary and Animal Sciences, Lahore.

Fabrication of buried nanostructures by atomic layer deposition.

We present a method for fabricating buried nanostructures by growing a dielectric cover layer on a corrugated surface profile by atomic layer deposition of TiO. Selecting appropriate process parameters, the conformal growth of TiO results in a smooth, nearly flat-top surface of the structure. Such a hard surface can be easily cleaned without damage, making the nanostructure reusable after contamination.

Effect of substrate overetching and heat treatment of titanium oxide waveguide gratings and thin films on their optical properties.

We investigate subwavelength titanium oxide (TiO2) resonance waveguide gratings (RWGs) and TiO2 thin films of thicknesses ~200  nm fabricated by atomic layer deposition (ALD), in both amorphous and crystalline phases on fused silica substrates. The TiO2 RWGs are fabricated by electron beam lithography, reactive ion etching, and ALD. The thin films and RWGs are characterized structurally by x-ray diffraction and scanning electron microscopy.
