Superstability of micrometre jets surrounded by a polymeric shell. [PDF]
J Appl CrystallogrSuperstable micrometre compound jets have been produced for serial femtosecond X‐ray crystallography.We have produced superstable compound liquid microjets with a 3D‐printed coaxial flow‐focusing injector. The aqueous jet core is surrounded by a shell, a few hundred nanometres in thickness, of a low‐concentration aqueous solution of a low‐molecular ...

A portable graphite calorimeter for onsite reference dosimetry and beam quality correction factor determination. [PDF]
J Appl Clin Med PhysAbstract Purpose To present a portable, reliable, and fast setup graphite calorimeter for onsite absolute dose measurements at hospitals. Methods We have designed and built a portable graphite calorimeter optimized for fast setup and accurate measurements at clinical centers. Our system has minimum readout and auxiliary electronics and is inserted in a

Differential xylem phytohormone export from dry and wet roots during partial rootzone drying is independent of shoot-to-root transport in soybean. [PDF]
Physiol PlantAbstract Different phytohormones can act as root‐to‐shoot signalling molecules in response to soil drying. Recent findings suggest that root ABA levels are predominantly leaf‐sourced and not locally synthesized, thus, ABA exported from the roots in the xylem is mostly recycled from the shoot.

Unraveling the dangerous duet between cancer cell plasticity and drug resistance
Computational and Systems Oncology, Volume 3, Issue 3, September 2023., 2023 Abstract Cancer cell plasticity is the ability of tumor cells to switch phenotypes and is one of the predominant requisites of cancer cells capable of undergoing metastasis. Cancer cell plasticity is also recognized as one of the major contributors to intratumoral heterogeneity, a critical factor underlying the progression of malignant tumors, which is

An a priori error analysis of a type III thermoelastic problem with two porosities
Numerical Methods for Partial Differential Equations, Volume 39, Issue 2, Page 1067-1084, March 2023., 2023 Abstract In this work, we study, from the numerical point of view, a type III thermoelastic model with double porosity. The thermomechanical problem is written as a linear system composed of hyperbolic partial differential equations for the displacements and the two porosities, and a parabolic partial differential equation for the thermal displacement.

Mechanistic insights into the heterogeneous response to anti‐VEGF treatment in tumors
Computational and Systems Oncology, Volume 1, Issue 2, June 2021., 2021 Abstract Vascular endothelial growth factor (VEGF) is a strong promoter of angiogenesis in tumors, and anti‐VEGF treatment, such as a humanized antibody to VEGF, is clinically used as a monotherapy or in combination with chemotherapy to treat cancer patients. However, this approach is not effective in all patients or cancer types.
