Schrödinger electrons interacting with optical gratings: quantum mechanical study of the inverse Smith–Purcell effect

open access: yesNew Journal of Physics, 2016
Slow swift electrons with low self-inertia interact differently with matter and light in comparison with their relativistic counterparts: they are easily recoiled, reflected, and also diffracted form optical gratings and nanostructures. As a consequence,

Baryon breakdown in black hole

open access: yesFrontiers in Physics, 2022
According to relativity theory, a black hole is a distinct region in spacetime; according to astronomical observations, it is a celestial body transforming matter into high-energy jets.

Photon-photon colliders

open access: yesProceedings Particle Accelerator Conference, 2002
Since the seminal work by Ginsburg, et al. (1984), the subject of giving the Next Linear Collider photon-photon capability, as well as electron-positron capability, has drawn much attention. A 1990 article by V.I. Telnov describes the situation at that time. In March 1994, the first workshop on this subject was held.

Effect of loss on multiplexed single-photon sources

open access: yesNew Journal of Physics, 2015
An on-demand single-photon source is a key requirement for scaling many optical quantum technologies. A promising approach to realize an on-demand single-photon source is to multiplex an array of heralded single-photon sources using an active optical ...

A semiclassical approach reproducing asymptotically the Heitler formula for atomic photoionization

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2020
The wave-corpuscle method for description of atomic photoionization by a flux of photons in the visible and X-ray range was developed and applied. Using the calculated photoionization probability in the asymptotics, we obtained the desired approximate ...

High-Fidelity Photonic Three-Degree-of-Freedom Hyperparallel Controlled-Phase-Flip Gate

open access: yesFrontiers in Physics, 2022
Encoding computing qubits in multiple degrees of freedom (DOFs) of a photonic system allows hyperparallel quantum computation to enlarge channel capacity with less quantum resource, and constructing high-fidelity hyperparallel quantum gates is always ...

The PTTG1/VASP axis promotes oral squamous cell carcinoma metastasis by modulating focal adhesion and actin filaments

open access: yesMolecular Oncology, EarlyView.
VASP was found to be overexpressed in metastatic oral squamous cell carcinoma (OSCC) tissues. Notably, PTTG1‐ and VASP‐deficient OSCC cells demonstrated suppressed metastatic properties by disrupting the interaction between the cytoskeleton and focal adhesion (FAs) in the filopodia region.

Particle radiotherapy for breast cancer

open access: yesFrontiers in Oncology, 2023
Breast cancer is the most common malignant tumor in female patients. Along with surgery, radiotherapy is one of the most commonly prescribed treatments for breast cancer.

Targeting the MDM2‐MDM4 interaction interface reveals an otherwise therapeutically active wild‐type p53 in colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study investigates an alternative approach to reactivating the oncosuppressor p53 in cancer. A short peptide targeting the association of the two p53 inhibitors, MDM2 and MDM4, induces an otherwise therapeutically active p53 with unique features that promote cell death and potentially reduce toxicity towards proliferating nontumor cells.

On the Remarkable Features of the Lower Limits of Charge and the Radiated Energy of Antennas as Predicted by Classical Electrodynamics

open access: yesAtmosphere, 2016
Electromagnetic energy radiated by antennas working in both the frequency domain and time domain is studied as a function of the charge associated with the current in the antenna.
