Shaped electrodes for adaptive X‐ray optics

open access: yesJournal of Synchrotron Radiation, EarlyView.
For adaptive X‐ray optics on high‐performance beamline optical systems, we describe an approach to mirror figure and slope control using patterned, shaped electrodes to control the local curvature on a lithium niobate substrate from a single applied voltage. Longitudinally continuous electrode patterns achieve target shapes without discontinuities, and

Improved theoretical prediction for the 2s hyperfine interval in helium ion

open access: yes, 2005
We consider the uncertainty of theoretical calculations for a specific difference of the hyperfine intervals in the 1s and 2s states in a light hydrogen-like atom.

PLGA‐particle‐based vaccine induces SARS‐CoV‐2‐specific antibody and T‐cell responses

open access: yesBritish Journal of Pharmacology, EarlyView.
A novel coronavirus disease 2019 (COVID‐19) vaccine encapsulating recombinant severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) spike receptor binding domain (RBD) with the double stranded RNA (dsRNA) analogue Riboxxim induces robust systemic and respiratory T‐ and B‐cell responses in mice.

Weak Decays of Doubly Heavy Baryons: Multi-body Decay Channels

open access: yes, 2017
The newly-discovered $\Xi_{cc}^{++}$ decays into the $ \Lambda_{c}^+ K^-\pi^+\pi^+$, but the experimental data has indicated that this decay is not saturated by any two-body intermediate state.

Diverging in Vivo Immune Response Patterns After Oral Food Challenge in Peanut Allergic Adults

open access: yesClinical &Experimental Allergy, EarlyView.
After the oral food challenge, peanut (PN)‐allergic adults were monitored over 4 weeks, which revealed diverging immune response patterns, with strong responders (SR) exhibiting heightened Ara h 2+ B cell expansion, PN sIgE induction and increasing PN‐specific Tconv. Weak responders (WR) had more activated PN‐specific Tregs.

High-Precision Optical Measurement of the 2S Hyperfine Interval in Atomic Hydrogen

open access: yes, 2003
We have applied an optical method to the measurement of the 2S hyperfine interval in atomic hydrogen. The interval has been measured by means of two-photon spectroscopy of the 1S-2S transition on a hydrogen atomic beam shielded from external magnetic ...

Designing for Sustainability: Emerging Professional Roles and Capabilities for Designers in the 21st Century

open access: yesInternational Journal of Art &Design Education, EarlyView.
Abstract Design Practice is shifting towards transdisciplinary, collaborative and problem‐based approaches in response to complex challenges of a changing world including societal issues and the climate crisis. However, the nature of emerging roles for designers aiming to contribute to sustainability transitions, and the capabilities that empower ...

On the existence of branched coverings between surfaces with prescribed branch data, II

open access: yes, 2006
For a given branched covering between closed connected surfaces, there are several easy relations one can establish between the Euler characteristics of the surfaces, their orientability, the total degree, and the local degrees at the branching points ...
