Ultra-precise readout of single nitrogen-vacancy (NV) spins holds promise for major advancements in quantum sensing, computing, and communication technologies. Here we present a rigorous open quantum theory capable of simultaneously capturing the optical, vibronic, and spin interactions of the negatively charged NV center, both in the presence and absence of plasmonic interaction. Our theory is verified against existing experiments in the literature.

- * A case of CHIKV was reported in a 32-year-old Indian male in Jeddah during the COVID-19 pandemic, initially misdiagnosed as dengue, with treatment involving paracetamol and vitamin C.
- * Genome sequencing and phylogenetic analysis revealed the 2021 CHIKV strain was genetically distinct from 2018 strains, showing similarities to Indian strains and containing specific mutations, indicating a need for further research on CHIKV prevalence in Saudi Arabia.
Article Synopsis
- Dengue remains a significant public health issue in Malaysia, with over 600,000 cases and 1,200 deaths recorded from 2015 to 2021, marking a 100% increase from the previous seven years.
- Recent studies on the molecular epidemiology of dengue in the country are scarce, prompting this analysis of 4,004 complete envelope gene sequences from all four dengue virus serotypes collected during the same period.
- The research found that the dengue virus populations in Malaysia are highly diverse, with ongoing turnover of genotypes, and indicated that Selangor and Johor are key areas for the emergence and spread of dengue, linked to extensive networks throughout South and East Asia.
The frequency of locally transmitted dengue virus (DENV) infections has increased in Europe in recent years, facilitated by the invasive mosquito species , which is well established in a large area of Europe. In Italy, the first indigenous dengue outbreak was reported in August 2020 with 11 locally acquired cases in the Veneto region (northeast Italy), caused by a DENV-1 viral strain closely related to a previously described strain circulating in Singapore and China. In this study, we evaluated the vector competence of two Italian populations of compared to an lab colony.

The last significant local transmission of Zika virus (ZIKV) with more than 450 cases was in 2016-2017. To monitor the situation and mitigate further transmission, case, entomological and wastewater-based surveillance were carried out.
