High yield fusion in a Staged Z-pinch [PDF]

open access: yes, 2008
We simulate fusion in a Z-pinch; where the load is a xenon-plasma liner imploding onto a deuterium-tritium plasma target and the driver is a 2 MJ, 17 MA, 95 ns risetime pulser.

Abdominal Physical Signs and Medical Eponyms: Movements and Compression [PDF]

open access: yesClinical Medicine & Research, 2018
Prior to the advent of modern imaging techniques, maneuvers were performed as part of the physical examination to further assess pathological findings or an acute abdomen and to further improve clinicians' diagnostic acumen to identify the site and cause of disease.

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

The Epistemology of Wrinkles: From Geology and Anatomy to Physiology [PDF]

open access: yesInternational Journal of Biomedicine, 2016
The author studies the geometry and physics of wrinkling – drawing from geology and animal biology. The general principles behind tension and compression wrinkles are the same in geology or dermatology.

The cytoskeletal control of B cell receptor and integrin signaling in normal B cells and chronic lymphocytic leukemia

open access: yesFEBS Letters, EarlyView.
In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

Conceptual design of heavy ion beam compression using a wedge

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2015
Heavy ion beams are a useful tool for conducting high energy density physics (HEDP) experiments. Target heating can be enhanced by beam compression, because a shorter pulse diminishes hydrodynamic expansion during irradiation.

B cell mechanobiology in health and disease: emerging techniques and insights into therapeutic responses

open access: yesFEBS Letters, EarlyView.
B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
