This work assesses the cortical and the sub-cortical neural activity recorded from rodents using entropy and mutual information based approaches to study how hypothermia affects neural activity. By applying the multi-scale entropy and Shannon entropy, we quantify the degree of the regularity embedded in the cortical and sub-cortical neurons and characterize the dependency of entropy of these re...

An energy efficient temperature sensor for constant temperature monitoring has been introduced in this paper. The proposed sensor doesn’t use BJT for sensing; instead it utilizes the temperature dependency of threshold voltage of MOSFETs for designing of this sensor. The sensor circuit is designed with separate biasing circuit for limiting the power dissipation of the circuit. Both PTAT and CTA...

The effects of temperature, salt concentration, and formamide concentration on the emission characteristics of commonly used fluorescent labels were evaluated on DNA microchips. The emission intensities of different fluorophores without hybridization were observed to vary, each to a different extent, to mainly temperature changes. Rhodamine red, TAMRA (tetramethylrhodamine), and dyes from the c...

Embedded channel waveguide Bragg gratings are fabricated in the Ormocer® hybrid polymers OrmoComp®, OrmoCore, and OrmoClad by employing a single writing step technique based on phase mask technology and KrF excimer laser irradiation. All waveguide Bragg gratings exhibit well-defined reflection peaks within the telecom wavelengths range with peak heights of up to 35 dB and -3 dB-bandwidths of do...

The temperature and salt dependencies of absorption by liquid water (H2O) and heavy water (D2O) were determined using a hyperspectral absorption and attenuation meter (WET Labs, AC-S). Sodium chloride (NaCl) was used as a proxy for seawater salts. There was no significant temperature (PsiT) or salt (PsiS) dependency of absorption at wavelengths <550 nm. At wavelengths >550 nm, PsiT exhibited pe...

based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. in the present research, 2d molecular dynamics simulations have been used to investigate such behaviors. performing the planar simulations can provide a ...

Cellular and tissue activities highly depend on environmental pH. Murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. We have studied the effect of pH on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. Various concentrations of NaHC03 were used to adjust the pH of the culture medium unde...
