Many protein and mRNA species occur at low molecular counts within cells, and hence are subject to large stochastic fluctuations in copy numbers over time. Development of computationally tractable frameworks for modelling stochastic fluctuations in population counts is essential to understand how noise at the cellular level affects biological function and phenotype. We show that stochastic hybr...

Abstract Optical fiber sensing technology has developed rapidly since the 1980s with development of optical and communication technology. It is a new type that uses light as carrier medium to sense transmit external signals (measurands). Distributed sensors (DFOS) can continuously measure physical parameters distributed along geometric path fiber. Meanwhile, spatial distribution change informat...

A singlemode-multimode-singlemode (SMS) fiber structure consists of a short section multimode fusion- spliced between two SMS fibers. The mechanism underpinning the operation an is interference and associated self-imaging. structures can be used in variety optical systems but are most commonly as sensors for parameters, ranging from macro-world measurands such temperature, strain, vibration, fl...

A Long Period Grating was fabricated in endlessly single mode photonic crystal fibre using a spatially-periodic electric arc discharge. The sensing characteristics of the grating were studied and it was found to possess an insensitivity to temperature, a bend sensitivity of 3.7 nm.m and a strain sensitivity of -2.0 pm/με. Introduction: Long period gratings (LPGs) consist of a large scale (hundr...

mycoplasma ovipneumoniae is an important respiratory pathogen of sheep across the world. in the present study nasal swab samples (n=778) were processed and 51isolates of m. ovipneumoniae were identified through biochemical tests and pcr. difference in the isolation rate among districts (n=12), age groups (n=3), breads (n=6) was assessed. similarly the isolate rate among healthy (n=513) and resp...

Biochemical reaction systems may be viewed as discrete event processes characterized by a number of states and state transitions. These systems may be modeled as state transition systems with transitions representing individual reaction events. Since they often involve a large number of interactions, it can be difficult to construct such a model for a system, and since the resulting state-level...

In this paper, we review the characteristics of critical wavelength (CWL)-existed fiber-optic Mach–Zehnder interferometers (MZIs), including special few-mode fibers and microfibers, their sensing applications in physical, chemical, marine fields. Owing to existence CWL transmission spectra, in-line MZIs show some specific characteristics. The closer peak/dip CWL, larger shift or related sensiti...

State of the art vibration-based condition monitoring at gearbox housings faces uncertainties in interpretation measurement data due to signal transformations and noise. The state research shows that direct measurements source vibrations with integrated sensors provide higher quality data. Capacitive MEMS seem predestined for integration, but there is limited covering compactly sensor systems b...

conclusions rectifying the life style is one of the most effective factors on the individuals’ health. an important part in the life style of individuals which is related to fasting is sleeping. early rising, in other words, the optimum time for sleeping is an aspect of fasting and it can be concluded that fasting is meaningful with early rising. sleeping well and having enough time to sleep fo...

The importance of standardization of laboratory test results has a long history traceable to the first proficiency testing results in 1947 that demonstrated large discrepancies among results from 59 hospital laboratories (1 ). The AACC published a series of monographs in 1953– 1972 titled Standard Methods of Clinical Chemistry that promoted a single measurement procedure (MP) for a measurand. T...
