Intelligent open-set MIMO recognition in OWC using a Siamese neural network.

Multiple-input multiple-output (MIMO) technology, a core component of 6G, has been widely adopted in optical wireless communication (OWC) systems. Accurate recognition of different MIMO types is essential for MIMO selection and demodulation. In this Letter, we propose an open-set MIMO recognition method for OWC systems using a Siamese neural network (SNN).

Exploring the Frontier: The Human Microbiome's Role in Rare Childhood Neurological Diseases and Epilepsy.

Emerging research into the human microbiome, an intricate ecosystem of microorganisms residing in and on our bodies, reveals that it plays a pivotal role in maintaining our health, highlighting the potential for microbiome-based interventions to prevent, diagnose, treat, and manage a myriad of diseases. The objective of this review is to highlight the importance of microbiome studies in enhancing our understanding of rare genetic epilepsy and related neurological disorders. Studies suggest that the gut microbiome, acting through the gut-brain axis, impacts the development and severity of epileptic conditions in children.

[Back space in regulations: legal frameworks of research with existing patient data].

Background: A subgroup of patients with severe mental illness (SMI) is underrepresented in scientific research, in part due to barriers around giving informed consent. This may lead to response bias and lack of knowledge about this group. Retrospective research with existing patient data is the only way to increase our knowledge for some patient groups.

RGB-Single-Chip OLEDs for High-Speed Visible-Light Communication by Wavelength-Division Multiplexing.

Organic light-emitting diodes (OLEDs) have been developed for high-speed transmitters of visible-light communication (VLC) but so far the possibility of direct fabrication of multiple colors on a single substrate has not been exploited for multi-Gbps data transmission. Very fast red-, green-, and blue (RGB)-emitting OLEDs are developed on a single substrate to realize high data transmission speed by wavelength division multiplexing (WDM). -6 dB electrical bandwidth of over 100 MHz is achieved for all colors by selecting fluorescent materials with nanosecond emission lifetimes and little overlap between their emission spectra and incorporating them into OLEDs designed for high-speed operation.

[Antibiotic treatment of invasive meningococcal infections].

ANTIBIOTIC TREATMENT OF INVASIVE MENINGOCOCCAL INFECTION. Invasive meningococcal infections (IMI) are extremely severe pathologies that justify very early antibiotic therapy to limit complications and death. Three different situations may arise: 1) clinical suspicion of purpura fulminans in the pre-hospital setting, 2 confirmed or strongly suspected IMI, 3) post-exposure chemoprophylaxis of a patient's contacts.
