Shadowing Loss Measurements in an Office Building Environment With Metal Wall and Closets at 3 and 7 GHz

open access: yesInternational Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
This study proposes measurement results of shadowing loss in a four‐story office building. Shadowing loss includes building entry, exit, indoor, and diffraction losses. Data were collected by adopting a local averaging stage loaded with an elevated work platform for up to two stories.

Approximate Analysis on a Wide Angle Biconical Antenna

open access: yesTongxin xuebao, 1984
In this paper, the broad band performance of a wideangle biconical antenna has been analysed and demonstrated. First, the formulas by which its pattern and input impedance can be calculated are developed.

Geospatial Analysis of Tsetse Infestation and Animal African Trypanosomiasis in Busia County, Kenya

open access: yesJournal of Parasitology Research, Volume 2026, Issue 1, 2026.
African trypanosomiasis (AT) is a vector‐borne disease caused by protozoan parasites of the genus Trypanosoma, primarily transmitted through the bite of infected tsetse flies in the genus Glossina. The disease is a major constraint to livestock production, causing reduced productivity, anemia, and mortality in affected animals.

Biconical antennas with unequal cone angles [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 1998
The problem of radiation and reception of electromagnetic waves associated with a spherically capped biconical antenna having unequal cone angles /spl psi//sub 1/ and /spl psi//sub 2/ is investigated. Both cones that comprise a bicone are excited symmetrically at the apices by a voltage source so that the only higher order modes are TM.

Zebra stripes: the questions raised by the answers

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2660-2680, December 2025.
ABSTRACT Multiple hypotheses have been suggested to explain why the three zebra species (Equus quagga, E. grevyi and E. zebra) are striped. We review how well these theories explain the nature (rather than simply the existence) of the stripes. Specifically, we explore how well different theories explain (i) the form of zebra stripes (especially on ...

Effects of Bandwidth on Millimeter Wave Channel Characteristics and Modeling Analysis in Indoor Scenarios

open access: yesRadio Science, Volume 60, Issue 10, October 2025.
Abstract This paper presents wideband indoor channel measurements in three of the millimeter wave (mmWave) bands for the fifth generation (5G) and beyond 5G (B5G) wireless systems. Measurements were conducted at the Ka‐band (36–41 GHz) and V‐band (50–75 GHz) in office and factory/industrial environments, using Durham University's custom‐designed ...

All‐in‐one optical microfiber with an interface for MRSA in biofilms: Integrating rapid quantitative analysis and synergistic antimicrobial therapy

open access: yesInfoMat, Volume 7, Issue 8, August 2025.
Aiming at the management of MRSA biofilms, an all‐in‐one optical microfiber that integrated rapid quantitative analysis with synergistic antimicrobial therapy is developed. The prepared interfacial‐functionalized optical microfiber demonstrates the ability to detect MRSA concentrations in infection sites, enhance therapeutic efficacy, and assess ...

BOAT‐SHAPED OBJECTS OF LEAD FROM LATE BRONZE AGE HALA SULTAN TEKKE, CYPRUS, AND THE ULUBURUN SHIPWRECK

open access: yesOxford Journal of Archaeology, Volume 44, Issue 3, Page 228-247, August 2025.
Summary This study examines four exceptional lead boat‐shaped objects recovered from the fourteenth‐century BC Chamber Tomb ZZ at the cemetery of the cosmopolitan city of Hala Sultan Tekke, Cyprus. A closely related lead object was also found in Stratum 1 of City Quarter 4 at Hala Sultan Tekke, dating to the early twelfth century BC.
