Preparation of Low-Temperature Solution-Processed High-κ Gate Dielectrics Using Organic-Inorganic TiO Hybrid Nanoparticles.

Organic-inorganic hybrid dielectric nanomaterials are vital for OTFT applications due to their unique combination of organic dielectric and inorganic properties. Despite the challenges in preparing stable titania (TiO) nanoparticles, we successfully synthesized colloidally stable organic-inorganic (O-I) TiO hybrid nanoparticles using an amphiphilic polymer as a stabilizer through a low-temperature sol-gel process. The resulting O-I TiO hybrid sols exhibited long-term stability and formed a high-quality dielectric layer with a high dielectric constant (κ) and minimal leakage current density.

The Utilization of Machine Learning Algorithms for Assisting Physicians in the Diagnosis of Diabetes.

This paper investigates the use of machine learning algorithms to aid medical professionals in the detection and risk assessment of diabetes. The research employed a dataset gathered from individuals with type 2 diabetes in Ninh Binh, Vietnam. A variety of classification algorithms, including Decision Tree Classifier, Logistic Regression, SVC, Ada Boost Classifier, Gradient Boosting Classifier, Random Forest Classifier, and K Neighbors Classifier, were utilized to identify the most suitable algorithm for the dataset.

Avian influenza A (H5N1) in 10 patients in Vietnam.

Background: Recent outbreaks of avian influenza A (H5N1) in poultry throughout Asia have had major economic and health repercussions. Human infections with this virus were identified in Vietnam in January 2004.

Methods: We report the clinical features and preliminary epidemiologic findings among 10 patients with confirmed cases of avian influenza A (H5N1) who presented to hospitals in Ho Chi Minh City and Hanoi, Vietnam, in December 2003 and January 2004.

Synthesis of certain 4'-substituted nucleosides.

We have developed general methods for the synthesis of 4'-fluoro- and 4'-methoxynucleosides by addition of iodinemonofluoride or iodine and methanol across the double bond of suitably protected 4',5'-unsaturated pyrimidine and purine nucleosides. The structures of these adducts have been determined by a combination of chemical, spectroscopic, and electrophoretic methods. The 4'-methoxy- and the uridine analogs of nucleocidin have been synthesized from the corresponding 4'-fluorouridine and 4'-methoxyadenosine derivatives.
