The proposed protocol features reliable and fast image transmission while periodically transmitting scalar data without interruption by allowing two networks, a LoRa network and a wireless sensor network, with different transmission characteristics to cooperate. It adopts the RT-LoRa protocol for periodic scalar data transmission and uses a WSN-based pipelined transmission method that leverages single-hop message transmission of a LoRa network for image transmission. Thus, it can not only eliminate the control message overhead for time synchronization, slot scheduling, and path establishment for pipelined image transmission in WSNs but also eliminate interferences within WSNs, such as data collisions and data and message collisions, during pipelined image transmission, thereby enabling high reliability and fast transmission.

Introduction: Carnitine Palmitoyltransferase II (CPT II) deficiency encompasses a spectrum of disorders, with the lethal neonatal form (LNF) representing the rarest and most severe. While there are numerous gene variants that can cause CPT II deficiency, only 16 variants of these are known to be associated with LNF. This report presents the case of a neonatal male diagnosed with lethal CPT II deficiency, characterized by the presence of two heterogeneous variants.

However, the existing QD lasers struggle to combine technologically relevant metrics of low threshold and long operating duration with considerable output powers. Here a new class of full-color QD lasers are reported, featuring low threshold, uninterrupted operation for dozens of hours, and multimilliwatt output under quasi-steady-state pumping, by coupling the high-gain QDs with a double-clad pumping scheme.

- - This phase 3 trial assessed the self-amplifying mRNA COVID-19 vaccine, ARCT-154, against the ChAdOx1-S adenovirus-vector vaccine in Vietnam, involving nearly 2,400 adult participants.
- - Both vaccines had similar safety profiles, with mainly mild-to-moderate side effects and few serious adverse events reported.
- - ARCT-154 showed higher neutralizing antibody responses and efficacy against COVID-19 compared to ChAdOx1-S, suggesting potential immunological advantages without compromising safety.
Article Synopsis
- Miniature random lasers are important for fields like barcoding, bioimaging, and on-chip technologies, but creating size-tunable, biocompatible versions has been difficult.
- This study used poly(lactic-co-glycolic) acid (PLGA), a medical-approved material, to create monodisperse dye-doped PLGA spheres with controllable sizes from 25 to 52 µm.
- The spheres showed strong lasing emissions at wavelengths of 610-640 nm and a high quality factor of 3100, with detailed analysis providing insights into their structure.
