To study influenza viruses in pigs in Sri Lanka, we examined samples from pigs at slaughterhouses. Influenza (H3N2) and A(H1N1)pdm09 viruses were prevalent during 2004-2005 and 2009-2012, ...respectively. Genetic and epidemiologic analyses of human and swine influenza viruses indicated 2 events of A(H1N1)pdm09 virus spillover from humans to pigs.
After multiple discrete introductions of influenza A(H1N1)pdm09 virus into Sri Lanka, the virus was transmitted among humans, then swine. The spread of virus between geographically distant swine ...farms is consistent with virus dispersal associated with a vehicle used for swine transportation, although this remains unproven.
Sequence-independent amplification and specific reverse transcription PCRs identified genogroup I and II picobirnaviruses in respiratory tracts of pigs. These data expand knowledge of picobirnavirus ...diversity and tropism. Genetic relationships between porcine respiratory and human enteric picobirnaviruses suggest cross-species transmission of picobirnaviruses between pigs and humans.

Dengue is an infection with a wider spectrum of disease manifestations, ranging from simple dengue fever to expanded dengue syndrome. Expanded dengue syndrome encompasses multiorgan involvement, ...including neurological manifestations such as dengue encephalitis, seizures, encephalopathy, coma, hemiparesis, etc. Herein, we present a case of a 50-year-old female with a background history of well-controlled type 2 diabetes mellitus and hypertension for five years on oral medication. The patient presented with a one-day history of altered levels of consciousness, agitation, and aggressive behavior. Before admission, she had a history of high-grade fever with chills and rigors for three days. Serial investigations were performed, and the diagnosis of dengue encephalitis was made amidst the absence of positive findings for encephalitis in most of the imaging modalities except in electroencephalogram (EEG), making this case unique. Initially, it was presumed to be meningoencephalitis. Hence, the patient was initiated on intravenous acyclovir and cefotaxime. After the definitive diagnosis of dengue encephalitis, the given medication was stopped after seven days of administration, and with supportive management, the patient made a successful recovery within 10 days.
This research focuses on identifying a new implementation of a machine learning approach for Non-intrusive load monitoring (NILM). We mathematically superimpose current profiles of individual ...appliances and compare against the actual combinational current profiles. This simple yet effective method is tested on combinations of 6 household devices in a typical low voltage residential installation and the high accuracy of correct identification confirms the proposed method is feasible. The proposed method eases the burden of the training phase which is considered as an inherent limitation of all supervised deep learning NILM models. We deploy the method on a Raspberry Pi 3 providing a solution to increase the scalability of NILM
The millisecond pulsar J1713+0747 underwent a sudden and significant pulse shape change between April 16 and 17, 2021 (MJDs 59320 and 59321). Subsequently, the pulse shape gradually recovered over ...the course of several months. We report the results of continued multi-frequency radio observations of the pulsar made using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) and the 100-meter Green Bank Telescope (GBT) in a three-year period encompassing the shape change event, between February 2020 and February 2023. As of February 2023, the pulse shape had returned to a state similar to that seen before the event, but with measurable changes remaining. The amplitude of the shape change and the accompanying TOA residuals display a strong non-monotonic dependence on radio frequency, demonstrating that the event is neither a glitch (the effects of which should be independent of radio frequency, \(\nu\)) nor a change in dispersion measure (DM) alone (which would produce a delay proportional to \(\nu^{-2}\)). However, it does bear some resemblance to the two previous "chromatic timing events" observed in J1713+0747 (Demorest et al. 2013; Lam et al. 2016), as well as to a similar event observed in PSR J1643-1224 in 2015 (Shannon et al. 2016).

The generic finite volume solver, ANSLib, has been extended to three dimensions and used to
verify the accurate computation of three-dimensional advection-diffusion and Poisson problems.
A simple ...cubic domain has been selected as the domain of interest. Over this domain a steady
state solution is computed for each model problem with 2nd, 3rd and 4th order accurate schemes.
Gauss quadrature is used to evaluate the flux integral to 2nd, 3rd and 4th order accuracy. The flux
scheme makes use of the centred scheme to model the viscous term and a simple upwind scheme
to model the advective fluxes. In both cases the existing k-exact least-square reconstruction code
is used to obtain the solution at each Gauss integration point to 2nd, 3rd and 4th order accuracy.
Newton-Krylov implicit time advance is used to obtain the steady state solution, implemented
using the GMRES algorithm.
Prior to subjecting ANSLib code to physical model problems, the code is first tested for the
correct enforcement of boundary constraints, accurate implementation of the solution
reconstruction, and flux integral evaluation in three dimensions. Relevant changes are made to
the code to obtain the desired behaviour.
Analytical solutions for the advection-diffusion and Poisson equations are derived to satisfy
Dirichlet and Neumann boundary conditions; these are used to compute the resulting discretized
error in numerically converged solutions. Accuracy assessment is completed through a
comparison of error norms for different mesh sizes for each test problem. Localized errors on the
domain for each problem at steady state are plotted. The efficiency of the code to obtain a
numerical converged solution is reported.
