Single- and double-slit collimating effects on fast-atom diffraction spectra [PDF]

open access: yes, 2016
Diffraction patterns produced by fast He atoms grazingly impinging on a LiF(001) surface are investigated focusing on the influence of the beam collimation. Single- and double- slit collimating devices situated in front of the beam source are considered.

Finally making sense of the double-slit experiment

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2017
Significance We put forth a time-symmetric interpretation of quantum mechanics that does not stem from the wave properties of the particle. Rather, it posits corpuscular properties along with nonlocal properties, all of which are deterministic.

Microglia limit brain tumor development by restricting tumor cell proliferation and inducing T‐cell immunity

open access: yesMolecular Oncology, EarlyView.
Microglia (BV2) and IL‐4‐treated BMDMs promote astrocytoma clustering and inhibit tumor growth, not shown in other macrophage cells. In vivo, microglial co‐implantation enhances CD8+ T cell infiltration, elevates Granzyme B, lowers circulating MDSCs, and extends survival only in immune‐competent mice, but not in immune‐deficient mice.

Two-Beam Emitting Via a Single Subwavelength Metal Slit Surrounded by Mixed-Period Dielectric Grooves

open access: yesIEEE Photonics Journal, 2013
We use mixed-period dielectric grooves to surround a single metal slit to realize two-beam nonsymmetrical and symmetrical emitting for the transmitted light emerged from the subwavelength slit.

Quasiconformal variation of slit domains [PDF]

open access: yes, 2001
We use quasiconformal variations to study Riemann mappings onto variable single slit domains when the slit is the tail of an appropriately smooth Jordan arc.

Electronically tunable extraordinary optical transmission in graphene plasmonic ribbons coupled to subwavelength metallic slit arrays

open access: yesNature Communications, 2016
Subwavelength metallic slit arrays have been shown to exhibit extraordinary optical transmission, whereby tunnelling surface plasmonic waves constructively interfere to create large forward light propagation.

Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

open access: yesFEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Dual acting slit control mechanism [PDF]

open access: yes, 1980
A dual acting control system for mass spectrometers is described, which permits adjustment of the collimating slit width and centering of the collimating slit while using only one vacuum penetration.

Enhanced Transmission and Reflection of Femtosecond Pulses by a Single Slit

open access: yes, 2006
We show that a physical mechanism responsible for the enhanced transmission and reflection of femtosecond pulses by a single subwavelength nanoslit in a thick metallic film is the Fabry-Perot-like resonant excitation of stationary, quasistationary and ...

The Electrochemistry with Lithium versus Sodium of Selenium Confined To Slit Micropores in Carbon.

open access: yesNano letters (Print), 2016
Substitution of selenium for sulfur in the cathode of a rechargeable battery containing Sx molecules in microporous slits in carbon allows a better characterization of the electrochemical reactions that occur.
