P32 ‘Skin fade’ haircut: an independent risk factor for tinea capitis?
British Journal of Dermatology, 2023Abstract Tinea capitis is a highly contagious infection, with peak incidence at 3–9 years; transmission occurs between infected persons or via contaminated surfaces. We examine three different cases, all presented to our department this summer.

On the Rician K-factor of Intra-Vehicle Fading Channels
2020 IEEE 31st Annual International Symposium on Personal, Indoor and Mobile Radio Communications, 2020In this paper, we investigate the fading characteristics in intra-vehicle channels based on a vehicle testbed and measurements which reflect the channel loss behavior contributed by attenuation and fading (large-scale and small-scale). We show that small-scale fading is dominant over other factors such as large-scale fading, which can be described with

Capacity-Fading Behavior Analysis for Early Detection of Unhealthy Li-Ion Batteries
IEEE transactions on industrial electronics (1982. Print), 2021Reliability testing on lithium-ion (Li-ion) batteries is critical to designing operational back-end strategies for developing portable electronics. In this article, we develop a capacity-fading behavior analysis for the early detection of unhealthy Li ...

Factors Influencing the Capacity Fade of Spinel Lithium Manganese Oxides
Journal of The Electrochemical Society, 2004With the aim of developing a better understanding of the capacity fading mechanisms of spinel manganese oxides, the percent capacity fade of a number of singly substituted LiMn 2-y M y O 4 (M = Li, Al, Ti, Co. Ni, and Cu and 0 ≤ y ≤ 0.2) and doubly substituted LiMn 2-y-z M y Li z O 4 (M = Al. Ti, Fe, Co, Ni, Cu, and Ga, 0 ≤ y ≤ 0. 1, and 0 ≤ z ≤ 0.1)

Influence of Meteorological Factors on Date Bunch Fading Disorder
2015Date bunch fading disorder (DBFD) has been one of the major issues facing date palm growers in recent decades. This order has caused high and non-compensable losses to date palm product. Despite numerous studies, predominantly focusing on the causes and mitigation methods of this disorder, no precise influencing factors have been established and ...

Frequency diversity improvement factor for rain fade mitigation in Malaysia
2015 IEEE International WIE Conference on Electrical and Computer Engineering (WIECON-ECE), 2015Microwave communication systems in tropical region like Malaysia, operating at higher frequency ranges, are degraded its performance severely during rains. Hence, the rain fade must be taken in consideration for the MW link design to track the service outage and quality.

Application of multipath shape factors in Nakagami-m fading channel
2009 International Conference on Wireless Communications & Signal Processing, 2009This paper introduces a new application of multipath shape factors that greatly simplifies the description of Nakagami-m fading channel. The three shape factors are angular spread, angular constriction and azimuthal direction of maximum fading. They are introduced to describe the first-order and second-order statistics of received signal fluctuations ...
