Drug Testing and Analysis, EarlyView.A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It

Plant diversity estimates of Mediterranean islands differ among biodiversity databases
Ecography, EarlyView.Large‐scale biodiversity databases encompass three main types of data for plants, namely single species point occurrences, co‐occurrences in vegetation plots, and checklists for specific areas. Evidence shows that such data types exhibit specific biases, reporting different species assemblages at local scales.

Preconditioned conjugate gradient methods for absolute value equations
Journal of Numerical Analysis and Approximation Theory, 2020 We investigate the NP-hard absolute value equations (AVE), \(Ax-B|x| =b\), where \(A,B\) are given symmetric matrices in \(\mathbb{R}^{n\times n}, \ b\in \mathbb{R}^{n}\).

ELECTROPHORESIS, EarlyView.A rapid and reliable SALLE–CZE–UV method was developed for the determination of phenolic preservatives in insulin formulations and human plasma. The approach provides efficient extraction, fast separation (< 6 min), and excellent sensitivity, precision, and recovery, meeting regulatory requirements for accurate quantification.

Optimization of Energy Efficiency in Photovoltaic Water Pumping Systems Using Neural Networks
Energy Science &Engineering, EarlyView.This study investigates an optimal control strategy for a photovoltaic (PV) water pumping system aimed at improving efficiency and autonomy in off‐grid applications. The system uses an induction motor with direct torque control and compares three maximum power point tracking (MPPT) techniques: neural network–based MPPT, Incremental Conductance (IC ...
