Active surveillance for zoonotic respiratory viruses is essential to inform the development of appropriate interventions and outbreak responses. Here we target individuals with a high frequency of animal exposure in Vietnam. Three‐year community‐based surveillance was conducted in Vietnam during 2013‐2016. We enrolled a total of 581 individuals (animal‐raising farmers, slaughterers, animal‐health workers, and rat traders), and utilized reverse transcription‐polymerase chain reaction to detect 15 common respiratory viruses in pooled nasal‐throat swabs collected at baseline or acute respiratory disease episodes. A respiratory virus was detected in 7.9% (58 of 732) of baseline samples, and 17.7% (136 of 770) of disease episode samples (P <.001), with enteroviruses (EVs), rhinoviruses and influenza A virus being the predominant viruses detected. There were temporal and spatial fluctuations in the frequencies of the detected viruses over the study period, for example, EVs and influenza A viruses were more often detected during rainy seasons. We reported the detection of common respiratory viruses in individuals with a high frequency of animal exposure in Vietnam, an emerging infectious disease hotspot. The results show the value of baseline/control sampling in delineating the causative relationships and have revealed important insights into the ecological aspects of EVs, rhinoviruses and influenza A and their contributions to the burden posed by respiratory infections in Vietnam. Highlights: We reported the detection of common respiratory viruses in individuals with a high frequency of animal exposure in Vietnam, an emerging infectious disease hotspot.

Popcorn noise of integrated inductive write/GMR read heads was characterized at various write currents and frequencies. The popcorn noise count tends to increase with write current and peaks at a certain frequency. This was attributed to heating-cooling cycles of heads induced by the write current, which rolls off with frequency. In fact, it was observed that write current heating peaks around the same frequency. The heating is caused by Joule heating of writer coils and eddy current loss of the writer core. A larger popcorn count was observed if the heat diffusion path is restrained, for example, by unloading heads from the media surface. The clock frequency at which the popcorn noise peaks is higher when tested with a pseudo-random write pattern instead of a single frequency pattern. Potential impact of high data rate and write current rise time of preamplifiers is discussed. Index Terms--Popcorn noise, write current heating, eddy current loss, write current rise time, inductive write head, spin valve read head.

Examines the size distribution of the nickel islands grown on silicon substrates using chemical vapor deposition. Use of scanning electron microscopy; Implication of thermodynamics for the narrow island size distribution; Suppression of island appearance frequency at the small-size tail of the distribution.

Granular cell tumour is a rare, mostly benign, soft tissue, neuroectodermal tumour, most commonly seen in the skin and peripheral soft tissue. There are no publications to date of PSMA-PET avidity in a granular cell tumour. In this 60 year old male, staging PSMA-PET for a localized intermediate risk prostate cancer incidentally identified a PSMA-avid left supraspinatus lesion, which was subsequently biopsy-proven as a granular cell tumour. We present the first case of PSMA-avid granular cell tumour and add to the growing literature documenting PSMA-PET avidity in benign and malignant lesions apart from prostate cancer., Competing Interests: None declared., (© The Author(s) 2024.
