Over the past decade, metal oxide semiconductors have attracted considerable attention because of their transparency, high intrinsic charge carrier mobility, and charge carrier density. Metal oxide semiconductors also provide a promising route to develop resistive memory devices because of the tunability of their conductivity via the removal of oxygen ions, forming oxygen vacancies that can act as electron donors. Here, this paper reports the fabrication of a resistive random-access memory (ReRAM) device with TiO and TiO layers and introduces a solution-processed InO-graphene oxide (GO) buffer layer from a water-based precursor solution to tune the switching characteristics.

We isolated three novel strains, S1, S2, and S5, from human oral cavities and identified them as distinct novel species. All these strains are facultatively anaerobic, Gram-stain-positive, and non-flagellated bacteria. Their optimal growth conditions for these strains were observed in Columbia broth (CB) at 37 °C, pH 7.

Article Synopsis
  • * By altering just two amino acids in the peptide structure, researchers found notable differences in how these peptides self-assemble, their stability, resistance to enzymes, and ability to penetrate human skin.
  • * The variations in peptide sequences caused changes in their shape, which could lead to the creation of more effective and simple delivery systems with desirable properties for medical applications.

Rationale: Transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) is used in tracheostomy but not in cases of airway obstruction. This case report explores the use of THRIVE for managing airway obstruction during tracheostomy in patients with subglottic and tracheal stenosis, thereby addressing the current knowledge gap and exploring its potential for airway management.

Patient Concerns: A 63-year-old female with subglottic and tracheal stenoses underwent tracheostomy.

Three novel bacterial strains, 321, 335, and 353, were isolated from the intestines of Aegosoma sinicum larvae collected from Paju-Si, South Korea. The strains were Gram-negative, obligate aerobe and had rod-shaped cells with a single flagellum. The three strains belonged to the genus Luteibacter in the family Rhodanobacteraceae and shared < 99.

Article Synopsis
  • - The study explored how the gut microbiome might affect cancer development, specifically looking at newly diagnosed patients with diffuse large B-cell lymphoma (DLBCL), finding significant differences in microbial composition compared to healthy individuals.
  • - Patients with DLBCL showed lower microbial diversity and higher levels of the Enterobacteriaceae family, which were linked to worse treatment outcomes, including shorter progression-free survival.
  • - The presence of Enterobacteriaceae was associated with complications like febrile neutropenia and had connections to specific cytokine levels, highlighting the need for further research on gut dysbiosis in lymphoma patients.

This paper examined the effects of no treatment versus plasma treatment, and femtosecond laser irradiation as pre-annealing processes on indium zinc oxide (IZO) films and annealing at high temperatures. The plasma pre-annealed multilayer stacked IZO TFTs showed better electrical properties with mobility enhancement from 2.45 to 7.

  • Several studies have shown that people with Parkinson's disease (PD) have a unique gut microbiome, but there's limited research on the oral microbiome's role in PD.
  • By using advanced shotgun metagenomic sequencing, researchers found significant differences in the oral and gut microbiome between PD patients and healthy individuals.
  • Notably, PD patients had higher levels of Lactobacillus in their mouths, which correlated with harmful gut bacteria, and their microbiome showed reduced gene markers for certain amino acid production but increased markers for antimicrobial resistance.

In the global construction industry, government policies have recently focused on smart construction technologies, such as those concerning the "smartization" of construction, improvements of productivity, and automation technologies. In addition, smart construction safety technologies (SCSTs) have been developed to ensure workers' safety, under the initiative of the private sector. In regards to overseas occupational safety, wearable technologies have been developed for various types of industries, and the integrated platform developments needed to link them have become mainstream.

Three aerobic, Gram-negative, and rod-shaped bacterial strains, designated strains G4M1, SM13, and L12M9, were isolated from the gut of Batillaria multiformis, Cellana toreuma, and Patinopecten yessoensis collected from the Yellow Sea in South Korea. All the strains grew optimally at 25°C, in the presence of 2% (w/v) NaCl, and at pH 7. These three strains, which belonged to the genus Polaribacter in the family Flavobacteriaceae, shared < 98.

Viridans group streptococci are a serious health concern because most of these bacteria cause life-threatening infections, especially in immunocompromised and hospitalized individuals. We focused on two alpha-hemolytic Streptococcus strains (I-G2 and I-P16) newly isolated from an ileostomy effluent of a colorectal cancer patient. We examined their pathogenic potential by investigating their prevalence in human and assessing their pathogenicity in a mouse model.

Prestressed concrete (PSC) is widely used for the construction of bridges. The collapse of several bridges with PSC has been reported, and insufficient grout and tendon corrosion were found inside the ducts of these bridges. Therefore, non-destructive testing (NDT) technology is important for identifying defects inside ducts in PSC structures.

Visual commonsense reasoning is an intelligent task performed to decide the most appropriate answer to a question while providing the rationale or reason for the answer when an image, a natural language question, and candidate responses are given. For effective visual commonsense reasoning, both the knowledge acquisition problem and the multimodal alignment problem need to be solved. Therefore, we propose a novel Vision-Language-Knowledge Co-embedding (ViLaKC) model that extracts knowledge graphs relevant to the question from an external knowledge base, ConceptNet, and uses them together with the input image to answer the question.
