The steady-state visual evoked potential in vision research: A review.

open access: yesJournal of Vision, 2015
Periodic visual stimulation and analysis of the resulting steady-state visual evoked potentials were first introduced over 80 years ago as a means to study visual sensation and perception. From the first single-channel recording of responses to modulated

Upacicalcet: A Novel Intravenous Calcimimetic Agent for Patients Undergoing Hemodialysis With Secondary Hyperparathyroidism

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Dynamic simulation of multiple-effect evaporation

open access: yesCase Studies in Thermal Engineering, 2022
The main purpose of this work is to simulate multiple-effect evaporation and its variation as a result of the interconnection between batch and continuous unit operations. Therefore, the challenges posed by the hybrid continuous-discrete character of the

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

SPECIALIZED SYMBOLIC COMPUTATION FOR STEADY STATE PROBLEMS

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2013
An implementation of symbolic computation for steady state problems is proposed in the paper. A mathematical basis is derived in order to specify the quantities that the implementation will concern.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Steady State Economy at Optimal Population Size

open access: yesThe Journal of Population and Sustainability, 2018
This paper reviews briefly the idea of a steady state economy from the ancient times to the present. It discusses some of the suggestions made by H. Daly in his model of a steady state economy and particularly the idea of a stable population. It suggests
