Some Reiteration Theorems for R, L, RR, RL, LR, and LL Limiting Interpolation Spaces

open access: yesJournal of Function Spaces, 2021
We consider the K-interpolation methods involving slowly varying functions. We establish some reiteration formulae including so-called L or R limiting interpolation spaces as well as the RR, RL, LR, and LL extremal interpolation spaces.

SatGeo-NeRF: Geometrically Regularized NeRF for Satellite Imagery [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences
We present SatGeo-NeRF, a geometrically regularized NeRF for satellite imagery that mitigates overfitting-induced geometric artifacts observed in current state-of-the-art models using three model-agnostic regularizers.

Satellite laser ranging at ultra-high PRF of hundreds of kilohertz all day

open access: yesFrontiers in Physics, 2022
Satellite laser ranging (SLR) had been operated at a pulse repetition frequency (PRF) from ∼10 Hz to 10 kHz; the ultra-high PRF of SLR (UH-SLR) is a trend of development.

BEYOND OBJECTS: OBJECTS

open access: yesInternational Journal of Cooperative Information Systems, 1992
Object-orientation offers more than just objects, classes and inheritance as means to structure applications. It is an approach to application development in which software systems can be constructed by composing and refining pre-designed, plug-compatible software components. But for this approach to be successfully applied, programming languages must

An aperture of 21 cm telescope with polarized coaxial for satellite laser ranging

open access: yesFrontiers in Physics, 2023
With the development of aerospace and space scientific research, satellite laser ranging (SLR) has put forward higher requirements for response speed, data density, and measurement accuracy. In coaxial common optical path laser ranging, the emitted laser

An object lesson in objection [PDF]

open access: yesJournal of Family Planning and Reproductive Health Care, 2008
Theres always been conscientious objection in medicine. The inherent egotistical "this is how its done and what youll do if you want to get on" attitude that medicine breeds means its often hidden. Or its tough to carry out your objection. I object to having to see patients - wait I havent finished yet - when Ive got laryngitis for instance. Most of us

Nikol’skii–Type Inequalities for Trigonometric Polynomials for Lorentz–Zygmund Spaces

open access: yesJournal of Function Spaces, 2020
Nikol’skii–type inequalities, that is inequalities between different metrics of trigonometric polynomials on the torus Td for the Lorentz–Zygmund spaces, are obtained. The results of previous paper “Nikol’skii inequalities for Lorentz–Zygmund spaces” are
