FPGA implementation of a sub-400ns 6G free-space optical wireless communications transmitter.

Future wireless networks are planned to service many applications with an Ultra Low-Latency (ULL) requirement. Numerous 6G systems have been proposed including more traditional electro-magnetic (EM) antenna transmissions and optical wireless communications (OWC). For extremely wide-band operation, the traditional approaches require digital pre-distortion and other processing techniques which, in turn, require more computational resources and processing times thus increasing latency.

A Consent Support Resource with Benefits and Harms of Vaccination Does Not Increase Hesitancy in Parents-An Acceptability Study.

It is unclear whether information given about the benefits and risks of routine childhood vaccination during consent may cue parental vaccine hesitancy. Parents were surveyed before and after reading vaccine consent information at a public expo event in Sydney, Australia. We measured vaccine hesitancy with Parent Attitudes about Childhood Vaccine Short Scale (PACV-SS), informed decision-making with Informed Subscale of the Decisional Conflict Scale (DCS-IS), items from Stage of Decision Making, Positive Attitude Assessment, Vaccine Safety and Side Effect Concern, and Vaccine Communication Framework (VCF) tools.

Detection and quantitation of synthetic cannabinoid receptor agonists in infused papers from prisons in a constantly evolving illicit market.

Drug misuse in prisons contributes to increased disruption and violence and negatively impacts prisoner safety, rehabilitation, and recovery. Synthetic cannabinoid receptor agonists (SCRAs), colloquially known as "spice", are infused into papers and are of particular concern in a prison setting where they are commonly vaped. Methods for the qualitative and quantitative analysis of SCRA infused papers, including impurity profiling, were developed using gas chromatography-mass spectrometry (GC-MS) with qualitative confirmation by ultra high pressure liquid chromatography with photodiode array and quadrupole time of flight mass spectrometry detection (UPLC-PDA-QToF-MS) and applied to 354 individual seized paper samples originating from 168 seizures from three Scottish prisons.
