This article studies the problem of stabilizing a leader-follower formation specified by a set of bearing constraints while disturbed by some unknown uniformly bounded disturbances. A set of leaders are positioned at their desired positions while each follower is modeled by a single integrator with an additive time-varying disturbance. Adaptive variable-structure control laws using displacements or only bearing vectors are applied to stabilize the desired formation.

Background: Pathogenic variants in the gene are associated with two distinct autosomal recessive neuromuscular disorders: spinal muscular atrophy with respiratory distress type 1 (SMARD1; OMIM #604320) and Charcot-Marie-Tooth type 2S (CMT2S; OMIM #616155). SMARD1 is a severe and fatal condition characterized by infantile-onset respiratory distress, diaphragmatic palsy, and distal muscular weakness, while CMT2S follows a milder clinical course, with slowly progressive distal muscle weakness and sensory loss, without manifestations of respiratory disorder.

Methods: Whole-exome sequencing of the gene was performed for eight Vietnamese patients with -related neuromuscular disorders including five patients with SMARD1 and the others with CMT2S.

In this study, strain DM10 was isolated from mangrove roots and characterized as a halotolerant plant growth-promoting bacterium. Strain DM10 exhibited the ability to solubilize phosphate, produce siderophore, show 1-aminocyclopropane-1-carboxylic acid deaminase activity, and hydrolyze starch. The rice plants subjected to a treatment of NaCl (200 mM) and inoculated with strain DM10 showed an improvement in the shoot length, root length, and dried weight, when compared to those exposed solely to saline treatment.

Background And Purpose: The utilization of doxorubicin (DOX) in clinal trials is also challenging owing to its adverse effects, including low oral bioavailability, generation of reactive oxygen species (ROS), cardiotoxicity, and epithelial barrier damage. Recently, scavenging of ROS reduced the cytotoxicity of DOX, suggesting a new approach for using DOX as an anticancer treatment. Thus, in this study, non-silica and silica redox nanoparticles (denoted as RNP and siRNP, respectively) with ROS scavenging features have been designed to encapsulate DOX and reduce its cytotoxicity.

We report on superconductivity in NdEuNiO using Eu as a 4f dopant of the parent NdNiO infinite-layer compound. We use an all-in situ molecular beam epitaxy reduction process to achieve the superconducting phase, providing an alternate method to the ex situ CaH reduction process to induce superconductivity in the infinite-layer nickelates. The NdEuNiO samples exhibit a step-terrace structure on their surfaces, have a onset of 21 K at = 0.

Discovery of reliable signatures for the empirical diagnosis of neurological diseases-both infectious and non-infectious-remains unrealized. One of the primary challenges encountered in such studies is the lack of a comprehensive database representative of a signature background that exists in healthy individuals, and against which an aberrant event can be assessed. For neurological insults and injuries, it is important to understand the normal profile in the neuronal (cerebrospinal fluid) and systemic fluids (e.

Article Synopsis
  • * A study involving 70 infants diagnosed with NDM at the Vietnam National Children's Hospital found that 78.5% had known mutations, with many experiencing diabetic complications but showing normal development after 5.5 years of insulin treatment.
  • * The research highlights that certain mutations are a common cause of permanent NDM and suggests that genetic screening for these mutations should be part of the diagnosis process for diabetic children in their first year of life.

Two-dimensional (2D) transition metal dichalcogenides (TMDCs), possessing unique exciton luminescence properties, have attracted significant attention for use in optical and electrical devices. TMDCs are also high refractive index materials that can strongly confine the electromagnetic field in nanoscale dimensions when patterned into nanostructures, thus resulting in complex light emission that includes exciton and dielectric resonances. Here, we use cathodoluminescence (CL) to experimentally visualize the emission modes of single molybdenum disulfide (MoS) nanoflakes and to investigate luminescence enhancement due to dielectric resonances in nanoscale dimensions, by using a scanning transmission electron microscope.
