Appearance of second harmonic in Jupiter’s and Saturn’s spectrum [PDF]
Astronomical School’s Report, 2003 There is considered the basis of nonlinear atmospheric optic. For our investigations, we used the spectral observations received by E.Karkoshka in 1993 and 1995 on the ESO (European Southern Observatory) from 300 to 1000 nm. We received such nonlinear optical effects as appearance of second harmonic of the methane bands in the Jupiter’s and Saturn’s ...

Organoids in pediatric cancer research
FEBS 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.

The use of joint attention in the naturalistic setting in children with Autism Spectrum Disorder [PDF]
, 2015 This study investigates the deficits in the quantity and quality of joint attention in children with Autism Spectrum Disorder (ASD). To obtain a holistic measure of joint attention, the following four aspects were considered: a) the quantity of ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS 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.

Improved method for detecting weak abrupt information based on permutation entropy
Advances in Mechanical Engineering, 2017 As a dynamic detecting method for abrupt information, permutation entropy could effectively reflect the subtle change in time series data, which is also simple and can be computed conveniently.

On ion gyro-harmonic structuring in the stimulated electromagnetic emission spectrum during second electron gyro-harmonic heating [PDF]
Annales Geophysicae, 2012 Recent observations show that, during ionospheric heating experiments at frequencies near the second electron gyro-harmonic, discrete spectral lines separated by harmonics of the ion-gyro frequency appear in the stimulated electromagnetic emission ...

Second spectrum of tungsten (W II)
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1964 A preliminary report on the second spectrum of tungsten, published in 1938, presented 27 even energy levels and 50 odd energy levels that were derived from 500 W II lines ranging in wavelength from 1961.43 Å to 4348.13 Å. The present paper submits data on 62 even levels, 132 odd levels, and 2,173 classified lines of W II, ranging in wavelength from ...

Dynamic Spectrum Sharing Models for Cognitive Radio Aided Ad Hoc Networks and Their Performance Analysis [PDF]
, 2011 In this paper, two dynamic spectrum sharing models are proposed, namely a Markov-chain model and a queue-based model in order, to evaluate the performance of CRAHNs, where the shared Primary Channels (PCs) are complemented by unshared Secondary Channels (

FEBS 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

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
