Efficient generation of Bessel-Gauss attosecond pulse trains via nonadiabatic phase-matched high-order harmonics

Light: Science & Applications
Generating Bessel-Gauss beams in the extreme ultraviolet (EUV) with attosecond pulse durations poses a significant challenge due to the limitations of conventional transmission optical components.

Precision atomic physics techniques for nuclear physics with radioactive beams [PDF]

, 2012
Atomic physics techniques for the determination of ground-state properties of radioactive isotopes are very sensitive and provide accurate masses, binding energies, Q-values, charge radii, spins and electromagnetic moments. Many fields in nuclear physics

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

FEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Born reciprocity and the 1/r potential

, 2007
Many structures in nature are invariant under the transformation (p,r)->(br,-p/b), where b is some scale factor. Born's reciprocity hypothesis affirms that this invariance extends to the entire Hamiltonian and equations of motion.

Breast Cancer and Aging: Understanding the Complex Relationship and Implications for Prevention and Screening

Aging and Cancer, EarlyView.
ABSTRACT Background Breast cancer is a multifactorial disease that affects many women worldwide. Age is the most important risk factor for breast cancer, with an increased incidence markedly after the age of 50. The relationships of aging to breast cancer have been thoroughly examined, and notable connections regarding various age‐related changes in ...

Colloquium: Atomic quantum gases in periodically driven optical lattices [PDF]

, 2016
Dynamics of quantum many-body systems is one of the most complex problems in physics since it involves the time evolution of a large number of particles that interact with each other under the influence of external forces. With ultracold atoms in optical

Progress of research on delaying bone destruction of rheumatoid arthritis by combining traditional Chinese and Western medicine

Advanced Chinese Medicine, EarlyView.
Abstract Rheumatoid arthritis (RA) is a common autoimmune disease with bone destruction as the core pathology, which belongs to the category of “impediment disease” in traditional Chinese medicine (TCM), and its etiology and pathogenesis are still not completely clear.

Evolution of water dynamics in the Prussian blue

EPJ Web of Conferences, 2015
Crystal water plays a crucial role towards the multifunctional properties of Prussian blue and its analogue (PBA) compounds. We have investigated the dynamics of crystal water in Prussian blue (PB), Fe(III)4[Fe(II)(CN)6]3.
