Wearable-based behaviour interpolation for semi-supervised human activity recognition (2024)
Journal Article
Duan, H., Wang, S., Ojha, V., Wang, S., Huang, Y., Long, Y., …Zheng, Y. (2024). Wearable-based behaviour interpolation for semi-supervised human activity recognition. Information Sciences, 665, Article 120393. https://doi.org/10.1016/j.ins.2024.120393

While traditional feature engineering for Human Activity Recognition (HAR) involves a trial-and-error process, deep learning has emerged as a preferred method for high-level representations of sensor-based human activities. However, most deep learnin... Read More about Wearable-based behaviour interpolation for semi-supervised human activity recognition.

The origin and speciation of orchids (2024)
Journal Article
Pérez‐Escobar, O. A., Bogarín, D., Przelomska, N. A. S., Ackerman, J. D., Balbuena, J. A., Bellot, S., …Antonelli, A. (2024). The origin and speciation of orchids. New Phytologist, 242(2), 700-716. https://doi.org/10.1111/nph.19580

Summary Orchids constitute one of the most spectacular radiations of flowering plants. However, their origin, spread across the globe, and hotspots of speciation remain uncertain due to the lack of an up-to-date phylogeographic analysis. We present...

High resolution divergent-beam X-ray topography (1970)
Journal Article
Tanner, B. K., & Humphreys, C. J. (1970). High resolution divergent-beam X-ray topography. Journal of Physics D: Applied Physics, 3(7), 1144-1146. https://doi.org/10.1088/0022-3727/3/7/421

The resolution and contrast of divergent-beam x-ray topographs is discussed. It is shown that tungsten Lα radiation can be used to reduce exposures and the x-ray examination of thinned electron microscope specimens is demonstrated.

The impact of load comparison errors on the power-of-d load balancing (2024)
Journal Article
Bhambay, S., Mukhopadhyay, A., & Vasantam, T. (2024). The impact of load comparison errors on the power-of-d load balancing. Performance Evaluation, 164, Article 102408. https://doi.org/10.1016/j.peva.2024.102408

We consider a system with 𝑛 unit-rate servers where jobs arrive according a Poisson process with rate 𝑛𝜆 (𝜆 < 1). In the standard Power-of-𝑑 or Pod scheme with 𝑑 ≥ 2, for each incoming job, a dispatcher samples 𝑑 servers uniformly at random and sends...

Oscillons in gapless theories (2024)
Journal Article
Dorey, P., Romańczukiewicz, T., Shnir, Y., & Wereszczyński, A. (2024). Oscillons in gapless theories. Physical Review D, 109(8), Article 085017. https://doi.org/10.1103/physrevd.109.085017

We show that large scale oscillons, i.e., quasiperiodic, long-living particlelike solutions, may exist in massless theories, too. Their existence is explained using an effective (smeared) mass threshold which takes into account nonlinear (finite) pe... Read More about Oscillons in gapless theories.
