Control of Residual Organic Solvents in Active Substances

open access: yesРегуляторные исследования и экспертиза лекарственных средств, 2022
Depending on the class of toxicity, organic solvents used or formed during the production of active substances may pose risks to human health. Therefore, residual Depending on the class of toxicity, organic solvents used or formed during the proorganic ...

An Object Oriented Model of a Railway Safety-Related Control System

open access: yesCommunications, 2002
There is a variety of methods and formalisms usable for writing specifications of railway interlocking and signalling systems or their subsystems. To write a consistent technical specification means to make a model with a required level of precision ...

Symbolic Analysis Applied to the Specification of Spatial Trends and Spatial Dependence

open access: yesEntropy, 2020
This article provides symbolic analysis tools for specifying spatial econometric models. It firstly considers testing spatial dependence in the presence of potential leading deterministic spatial components (similar to time-series tests for unit roots in

Restricted nature of adult neural stem cells: re-evaluation of their potential for brain repair.

open access: yesFrontiers in Neuroscience, 2014
Neural stem cells (NSCs) in the walls of the lateral ventricles continue to produce new neurons and oligodendrocytes throughout life. The identification of NSCs, long-range neuronal migration, and the integration of new neurons into fully formed mature ...

Microscopy-BIDS: An Extension to the Brain Imaging Data Structure for Microscopy Data

open access: yesFrontiers in Neuroscience, 2022
The Brain Imaging Data Structure (BIDS) is a specification for organizing, sharing, and archiving neuroimaging data and metadata in a reusable way. First developed for magnetic resonance imaging (MRI) datasets, the community-led specification evolved ...

A note on measure and expansiveness on uniform spaces

open access: yesApplied General Topology, 2019
We prove that the set of points doubly asymptotic to a point has measure zero with respect to any expansive outer regular measure for a bi-measurable map on a separable uniform space.

Logics and properties of a genetic regulatory program that drives embryonic muscle development in an echinoderm

open access: yeseLife, 2015
Evolutionary origin of muscle is a central question when discussing mesoderm evolution. Developmental mechanisms underlying somatic muscle development have mostly been studied in vertebrates and fly where multiple signals and hierarchic genetic ...

A New Approach to Model Verification, Falsification and Selection

open access: yesEconometrics, 2015
This paper shows that a qualitative analysis, i.e., an assessment of the consistency of a hypothesized sign pattern for structural arrays with the sign pattern of the estimated reduced form, can always provide decisive insight into a model’s validity ...

RNA-binding protein Elavl1/HuR is required for maintenance of cranial neural crest specification

open access: yeseLife, 2022
While neural crest development is known to be transcriptionally controlled via sequential activation of gene regulatory networks (GRNs), recent evidence increasingly implicates a role for post-transcriptional regulation in modulating the output of these ...
