Reduction of background scattered light in vacuum systems for cold atoms experiments

open access: yesAIP Advances, 2020
Recent advances in the understanding and control of cold atom systems have resulted in devices with extraordinary metrological performance. To further improve the performance in these systems, additional methods of noise reduction are needed.

Lipid nanoparticles with aptamers enable targeted mRNA delivery to CD4⁺ T cells

open access: yesDrug Delivery
In vivo genetic engineering of T cells could overcome the logistical, biological, and safety challenges of ex vivo modification, but effective and safe delivery systems remain limited by a lack of cellular specificity.

Removable Edges on a Hamilton Cycle or Outside a Cycle in a 4-Connected Graph

open access: yesDiscussiones Mathematicae Graph Theory, 2021
Let G be a 4-connected graph. We call an edge e of G removable if the following sequence of operations results in a 4-connected graph: delete e from G; if there are vertices with degree 3 in G− e, then for each (of the at most two) such vertex x, delete ...

Atom-by-Atom Determination of Deuterium Atom Distribution in the Surface by Atom Probe.

open access: yesSHINKU, 1998
Hydrogen is a major residual gas constituent in extremely high vacuum (XHV) and its outgassing behavior has been suggested to be closely related to its concentration and distribution in the surface layers of materials used to fabricate vacuum chambers.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Experiments in Cavity QED: Exploring the Interaction of Quantized Light with a Single Trapped Atom [PDF]

open access: yes, 2005
The experiments discussed in this thesis focus on the interaction of a single trapped atom with the single mode of a high-finesse optical cavity, in the regime of strong coupling.
