(previously known as ) infection is not common in Hong Kong. is a fish-borne cestode parasite that infects humans after consuming raw or insufficiently cooked fish containing plerocercoids. We reported a case of infection in a 40-year-old woman who presented with a complaint of epigastric pain and diarrhea.

Reservoir computing (RC) is a powerful machine learning algorithm for information processing. Despite numerous optical implementations, its speed and scalability remain limited by the need to establish recurrent connections and achieve efficient optical nonlinearities. This work proposes a streamlined photonic RC design based on a new paradigm, called next-generation RC, which overcomes these limitations.

Background: Screening for frequent hospitalizations in the community can help prevent super-utilizers from growing in the inpatient population. However, the determinants of frequent hospitalizations have not been systematically examined, their operational definitions have been inconsistent, and screening among community members lacks tools. Nor do we know if what determined frequent hospitalizations before COVID-19 continued to be the determinant of frequent hospitalizations at the height of the pandemic.

Article Synopsis
  • The study followed patients with early-stage follicular lymphoma (ESFL) who were treated with involved field radiotherapy (IFRT) alone or combined with chemotherapy (cyclophosphamide/vincristine/prednisolone) and later added rituximab to the treatment, analyzing its effects over an 11.3-year period.* -
  • Results showed that those receiving IFRT plus rituximab (IFRT + R-CVP) had significantly better progression-free survival rates (62% vs. 43%) compared to IFRT alone, even though overall survival rates didn’t differ significantly.* -
  • Additionally, higher expression of the CD8A gene in biopsy samples was associated with improved outcomes, suggesting that immune

We propose and validate a new, to the best of our knowledge, approach for high coupling efficiency polarization splitting waveguide grating couplers (PSWGCs). The high coupling efficiency is achieved by using a polysilicon overlay grating, which is shifted with respect to the underlying silicon grating. The PSWGC is designed to couple the two orthogonal polarizations in different directions.
