DERIVATION ON SEVERAL RINGS

open access: yesBarekeng
Research on ring derivation is one of the studies that is quite popular among algebra lovers. The definition of the derivation on the ring is motivated by the derivation in calculus which has Leibniz's rule.

RCVS–TCH score can predict reversible cerebral vasoconstriction syndrome in patients with thunderclap headache

open access: yesScientific Reports, 2021
Reversible cerebral vasoconstriction syndrome (RCVS) is one of the most important differential diagnosis in patients with thunderclap headache (TCH). We aimed to develop a new scoring system for RCVS in patients with TCH.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

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.

Derived Sets in Multiobjective Optimization

open access: yesZeitschrift für Analysis und ihre Anwendungen, 1994
In the present paper the theory of derived sets established by M. R. Hestenes and J. W. Nieuwenhuis for optimization problems with a real-valued objective function and a finite number of constraints is extended to multiobjective optimization problems.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Derived and integral sets of basic sets of polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1953
For the general terminology used in this paper the reader is referred to Whittaker's books [2; 3]. I shall investigate the mode of increase and the effectiveness of basic derived and integral sets of any finite order. So far as I know, this is done here for the first time. Let pn(z)= i p iziq n(z) = q qizi be two basic sets; then the product set {Un(z)
