Spin-dependent properties of a two-dimensional electron gas with ferromagnetic gates

open access: yes, 2002
A theoretical prediction of the spin-dependent electron self-energy and in-plane transport of a two-dimensional electron gas in proximity with a ferromagnetic gate is presented. The application of the predicted spin-dependent properties is illustrated by

The public role of the university professor [PDF]

open access: yes, 2004
This article suggests that college and university professors consider taking on a more public role that carries them, with greater frequency, beyond the iron gates or concrete pavements of their own academic institutions into the public sphere – not ...

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment

open access: yesAging and Cancer, EarlyView.
Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.

Developmental, Neuroanatomical and Cellular Expression of Genes Causing Dystonia

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Dystonia is one of the most common movement disorders, with variants in multiple genes identified as causative. However, an understanding of which developmental stages, brain regions, and cell types are most relevant is crucial for developing relevant disease models and therapeutics.

New universal gates for topological quantum computation with Fibonacci-$\boldsymbol{\varepsilon}$ composite Majorana edge modes on topological superconductor multilayers

open access: yes, 2020
We propose a new design of universal topological quantum computer device through a hybrid of the 1-, 2- and 7-layers of chiral topological superconductor ($\chi$TSC) thin films.

DNA-binding transferrin conjugates as functional gene-delivery agents: synthesis by linkage of polylysine or ethidium homodimer to the transferrin carbohydrate moiety [PDF]

open access: yes, 1991
We have previously demonstrated that transferrin-polycation conjugates are efficient carrier molecules for the introduction of genes into eucariotic cells.
