Abstract We have built an ytterbium optical lattice clock with improvements over our previous version. An in-vacuum blackbody radiation (BBR) shield is employed to provide a well characterized BBR environment. The effective temperature felt by the atoms can be determined at accuracy level of 13 mK, leading total frequency shift uncertainty 9.5 × 10 ?19 . also ultra-stable cavity system pre-stab...

Silicon dioxide (SiO<sub>2</sub>) is an important component of nuclear reactor optical fiber and also a candidate material for wast solidification. Owing to its special physical chemical characteristics, it used in many different technology fields like optics, electronics, energy orspace. Swift heavy ion irradiation can modify the crystal structure property SiO<sub>2</sub&g...

background: the presence of rennin-angiotensin components in mammalian ovaries and their involvement in ovarian physiology have been established. in the present study, effects of angiotensin ii (ang ii) on sodium-potassium adenosine triphosphatase (na+/k+/atpase) expression and development of sheep embryos was evaluated. methods: the abattoir-derived cumulus oocyte complexes (coc) were randomly...

The surface passivation of a CMOS image sensor (CIS) is highly beneficial for the overall improvement device performance. We employed thermal atomic layer deposition (T-ALD) and plasma enhanced (PE-ALD) techniques 20 nm HfO2 as well stacked with 3 5 Al2O3 thin films. HfO2/Si Al2O3/HfO2/Si metal-oxide-semiconductor stru...

Low-loss waveguides constitute an important building block for integrated photonic systems. In this work, we investigated low-loss photonic device fabrication in Ge23Sb7S70 chalcogenide glass using electron beam lithography followed by plasma dry etching. High-index-contrast waveguides with a low propagation loss of 0.5 dB/cm and microdisk resonators with an int...

Non-small cell lung cancer (NSCLC) has evolved into the deadliest in present scenario. The progression of NSCLC is mainly due to dysregulation tyrosine kinase family's epidermal growth factor receptor (EGFR). Thus, EGFR been widely studied as a major target treatment NSCLC, but lack selectivity and drug resistance limit use existing therapeutic agents. Considering urgent necessity for advanced ...

we have designed a new type of optical channel drop filter (cdf) based on two dimensionaltriangular lattice photonic crystals. cdf operation is based on coupling to the photonic crystalwaveguide. the proposed structure is optimized to work as a cdf for obtaining the cdfcharacteristics and band structure of the filter the finite difference time domain (fdtd) method andplane wave expansion (pwe) ...
