We propose new diagnostics for circumstellar interaction in Type IIP supernovae (SNe IIP) by the detection of high velocity (HV) absorption features in Hα and He I 10830 Å lines during the photospheric stage. To demonstrate the method, we compute the ionization and excitation of H and He in supernova ejecta taking into account time-dependent effects and X-ray irradiation. We find that the inter...

This paper presents the application of two swarm intelligence techniques, multi-objective artificial bee colony (MOABC) and particle optimization (MOPSO), to optimal design a complementary metal oxide semiconductor (CMOS) low noise amplifier (LNA) cascode with inductive source degeneration. The aim is achieve balanced trade-off between voltage gain figure. optimized LNA circuit operates at 2.4 ...

Titanium alloys are ideal for a great range of engineering applications; however, their high manufacturing costs hinder widespread use. This study investigates the relationship between processing and properties representative Ti-based materials manufactured via powder metallurgy in order to reduce costs. is possible as techniques near-net shape processes with yield material. It found that relat...

The CERN RD50 CMOS working group is designing and characterizing depleted monolithic active pixel sensors (DMAPS) for use in high radiation environments fabricated the LFoundry 150 nm HV-CMOS process. first iteration of this chip, RD50-MPW1, suffered from leakage current, low breakdown voltage crosstalk. In order to mitigate these shortcomings, an improved version with geometry was designed. RD...

Castleman's disease (CD) (angiofollicular lymph node hyperplasia) was first described in 1936 (1). It is a rare disease of unknown aetiology affecting the lymph nodes. CD consists of two basic histological types: hyaline-vascular (HV) and plasma-cell (PC), and a mixed type called hyaline-vascular plasma cell type (HV-CV) (2). Clinically, it presents as an indolent disease confined to a single s...

Three different pixels based on single-photon avalanche diodes for triggered applications, such as fluorescence lifetime measurements and high energy physics experiments, are presented. Each pixel consists of a 20 mm 100 mm (width length) single photon avalanche diode and a monolithically integrated readout circuit. The sensors are operated in the gated mode of acquisition to reduce the probabi...
