Conflicting perceptions of the status of field biology and identification skills in UK education [PDF]

open access: yes, 2016
There is an enormous degree of engagement between people and the outdoors in the UK; 58% of the adult population of England, about 24 million people, make at least one visit a week to parks, urban green spaces, the countryside or other outdoor ...

Ultra-deep sequencing of 45S rDNA to discern intragenomic diversity in three Chrysodeixis species for molecular identification

open access: yesScientific Reports, 2023
Species identification is necessary to prevent introductions of exotic plant pests through global trade. Many of these pests are understudied and lack publicly available DNA sequence data on which rapid molecular identification methods can be based.

Global parameter identification of stochastic reaction networks from single trajectories [PDF]

open access: yes, 2011
We consider the problem of inferring the unknown parameters of a stochastic biochemical network model from a single measured time-course of the concentration of some of the involved species.

Identification of Piecewise Linear Models of Complex Dynamical Systems

open access: yes, 2011
The paper addresses the realization and identification problem or a subclass of piecewise-affine hybrid systems. The paper provides necessary and sufficient conditions for existence of a realization, a characterization of minimality, and an ...

Leveraging a Relationship with Biology to Expand a Relationship with Physics

open access: yes, 2015
This work examines how experiences in one disciplinary domain (biology) can impact the relationship a student builds with another domain (physics).

Toxin–antitoxin systems [PDF]

open access: yesMobile Genetic Elements, 2013
Toxin-antitoxin (TA) systems are small genetic elements composed of a toxin gene and its cognate antitoxin. The toxins of all known TA systems are proteins while the antitoxins are either proteins or non-coding RNAs. Based on the molecular nature of the antitoxin and its mode of interaction with the toxin the TA modules are currently grouped into five ...

Systems Biology: Identifiability Analysis and Parameter Identification via Systems-Biology-Informed Neural Networks

open access: yes, 2023
The dynamics of systems biological processes are usually modeled by a system of ordinary differential equations (ODEs) with many unknown parameters that need to be inferred from noisy and sparse measurements. Here, we introduce systems-biology informed neural networks for parameter estimation by incorporating the system of ODEs into the neural networks.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
