Ανάλυση κύριων συνιστωσών (PCA, OPLS-DA MODELS): εφαρμογές στην βιοπληροφορική

, 2023
Η PCA είναι μια μέθοδος υψηλής πρακτικής σημασίας σε πολλές εφαρμογές στατιστικής συμπερασματολογίας, ιδίως όταν αντιμετωπίζεται το πρόβλημα της συσχέτισης πολλών ανεξάρτητων μεταβλητών με πολλές εξαρτημένες μεταβλητές αποτελέσματα χωρίς αρκετές ...

A Co‐Designed Implicit‐Reset Path PFD and Current Mismatch Compensated CP Enabling Sub‐0.5% Mismatch and Dead Zone‐Free for Low‐Spur PLLs

International Journal of Circuit Theory and Applications, EarlyView.
A co‐designed implicit‐reset phase‐frequency detector (PFD) and nonlinear amplifier‐assisted charge pump (CP) achieve dead zone‐free operation from 10 MHz to 4.7 GHz with < 0.5% current mismatch without calibration, enabling −80 dBc of reference spur and 0.50 ps of RMS jitter in a 180 nm of CMOS PLL.

OPLS-DA Model Results.

, 2014
*R2X and R2Y represent the goodness of fit between the X (metabolite data) and Y (predictor values) matrices. Q2 assesses the accuracy and predictability of the model. A Q2 value close to 1.0 represents a more predictive model.OPLS-DA Model Results.

Zebrafish inversin mutants develop scoliosis in the absence of laterality defects

Developmental Dynamics, EarlyView.
Abstract Background Human mutations in INVERSIN are associated with nephronophthisis, variable penetrance of situs inversus and congenital heart disease. Inversin has been shown to localize to cilia and many of the patient phenotypes are attributed to disrupted cilia function.

Theoretical Studies of Concentrated Aqueous Urea Solutions Using Computacional Monte Carlo Simulation

Journal of the Brazilian Chemical Society, 2002
Monte Carlo simulations were carried out for concentrated aqueous urea solutions at 4, 5, 6, 7 and 8 mol L-1 in the NpT ensemble at 298 K and 1 atm. The potential energy surfaces were represented by the sum of Coulomb and Lennard-Jones potentials in ...

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

Environmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.
