Rethinking the potential role of dose painting in personalized ultra-fractionated stereotactic adaptive radiotherapy [PDF]
Fractionated radiotherapy was established in the 1920s based upon two principles: (1) delivering daily treatments of equal quantity, unless the clinical situation requires adjustment, and (2) defining a specific treatment period to deliver a total dosage.

Effect of PECVD SiNx deposition process parameters on electrical properties of SiNx/AlGaN/GaN structures [PDF]
The effect of parameters of plasma enhanced chemical vapor deposition (PECVD) processes for SiNx film fabrication on the electrical parameters of dielectric/АlGaN/GaN structures has been studied.

Optimization of passivation in AlGaN/GaN heterostructure microwave transistor fabrication by ICP CVD [PDF]
We have studied the effect of silicon nitride (SiN) dielectric passivating film deposition by inductively coupled plasma chemical vapor deposition (ICP CVD) on the parameters of AlGaN/GaN heterostructure high electron mobility transistors (HEMT).

Control of yellow photoluminescence in AlGaN/GaN heterostructures [PDF]
Photoluminescence with the peak corresponding to yellow color of the visible spectrum (so-called yellow luminescence) originates from deep levels in the GaN buffer layers of heterostructures and depends on heterostructure growth conditions.

Theoretical Study of Gamma-ray Pulsars [PDF]
We use the non-stationary three dimensional two-layer outer gap model to explain gamma-ray emissions from a pulsar magnetosphere. We found out that for some pulsars like the Geminga pulsar, it was hard to explain emissions above a level of around 1 GeV.

Vacuum ultraviolet coherent undulator radiation from attosecond electron bunches
Attosecond duration relativistic electron bunches travelling through an undulator can generate brilliant coherent radiation in the visible to vacuum ultraviolet spectral range.

Laser wakefield accelerators (LWFAs) can produce high-energy electron bunches in short distances. Successfully coupling these sources with undulators has the potential to form an LWFA-driven free-electron laser (FEL), providing high-intensity short ...

CONNECTION OF ADDITIONAL PULSAR EMISSION COMPONENTS IN THE CRAB WITH THE RESONANCE REFLECTION FROM A NEUTRON STAR [PDF]
Purpose: The subject of the paper is discussion of reflected radiation from the neutron star surface. Such radiation, as was shown earlier by S. V. Trofymenko and one of the authors, occurs when reflects the radiation of relativistic positrons flying ...

In this paper, the possibility of periodic pulsar-like gamma-ray emission from the white dwarfs in AE Aquarii and AR Scorpii is investigated. We show that the white dwarf magnetospheres in AE Aquarii and AR Scorpii can possibly induce potentials to ...

FIRST DETECTION AT THE DECAMETER WAVELENGTHS AND CLARIFICATION OF RADIATION PARAMETERS OF PSR J2325-0530, PSR J0613+3731, AND PSR J1426+52 RADIO PULSARS [PDF]
Purpose: Due to the significant increase of a number of pulsars discovered with high-frequency radio telescopes over the last ten years and the necessity to obtain accurate parameters of their decameter radiation (as well as to identify single pulses ...
