Comparative Analysis of Binhu and Cosmic-2 Radio Occultation Data

open access: yesRemote Sensing, 2022
Global Navigation Satellite System (GNSS) radio occultation (RO) technology has been widely used in Earth atmospheric detection and has a significant impact on numerical weather prediction (NWP), climate detection, and other fields. Cosmic-2 LEO-1 (C2E1)

The cosmic microwave background Cold Spot anomaly: the impact of sky masking and the expected contribution from the Integrated Sachs-Wolfe effect [PDF]

open access: yes, 2017
We re-analyse the cosmic microwave background (CMB) Cold Spot (CS) anomaly with particular focus on understanding the bias a mask (contaminated by Galactic and point sources) may introduce.

The GMRT 150 MHz all-sky radio survey - First alternative data release TGSS ADR1 [PDF]

open access: yes, 2016
We present the first full release of a survey of the 150 MHz radio sky, observed with the Giant Metrewave Radio Telescope (GMRT) between April 2010 and March 2012 as part of the TIFR GMRT Sky Survey (TGSS) project.

Kaluza-Klein Masses and Couplings: Radiative Corrections to Tree-Level Relations

open access: yes, 2011
The most direct experimental signature of a compactified extra dimension is the appearance of towers of Kaluza-Klein particles obeying specific mass and coupling relations. However, such masses and couplings are subject to radiative corrections.

Radiative sky cooling: Fundamental principles, materials, and applications

open access: yesApplied Physics Reviews, 2019
Radiative sky cooling cools an object on the earth by emitting thermal infrared radiation to the cold universe through the atmospheric window (8–13 μm). It consumes no electricity and has great potential to be explored for cooling of buildings, vehicles,

Image of Shamanic Cosmos in Cyprus Turkish Folktales / Kıbrıs Türk Masallarında Şamanistik Evren Tasavvuru [PDF]

open access: yesFolklor/Edebiyat, 2016
From mythology to celestial religions, cosmos is conceived of three parts. These are the sky where good gods are in, the earth where people live in and the underworld where bad gods and spirits are in. The sky is made up seven, nine or seventeen layers

Projective Cross-Ratio on Hypercomplex Numbers

open access: yes, 2012
The paper presents a new cross-ratio of hypercomplex numbers based on projective geometry. We discuss the essential properties of the projective cross-ratio, notably its invariance under Mobius transformations.

Spectroscopic Target Selection in the Sloan Digital Sky Survey: The Main Galaxy Sample [PDF]

open access: yes, 2002
We describe the algorithm that selects the main sample of galaxies for spectroscopy in the Sloan Digital Sky Survey (SDSS) from the photometric data obtained by the imaging survey.

BATSE Sky Exposure [PDF]

open access: yes, 1997
Angular sky exposure is presented for a number of published BATSE gamma-ray burst catalogs. A new algorithm was required due to telemetry gaps resulting from onboard tape recorder failures; the new algorithm improves the 1B Catalog exposure calculation ...

The Sky Is Not the Limit: LTE for Unmanned Aerial Vehicles [PDF]

open access: yesIEEE Communications Magazine, 2017
Many use cases of UAVs require beyond visual LOS communications. Mobile networks offer wide-area, high-speed, and secure wireless connectivity, which can enhance control and safety of UAV operations and enable beyond visual LOS use cases. In this article,
