Investor attention and corporate social responsibility of family businesses in Vietnam: The moderating role of CEO overpower.

This study examines the influence of investor attention and Chief Executive Officers (CEOs) power on Corporate Social Responsibility (CSR) within Vietnamese family businesses. Unlike most of the past literature, this study further investigates the potential moderating effects of CEOs' power on the relationship between investor attention and CSR. Utilizing the dynamic system Generalized Method of Moments (GMM), this study analyzes a dataset comprising 116 Vietnamese family businesses from 2005 to 2020.

Prevalence, multidrug resistance, and biofilm formation of Vibrio parahaemolyticus isolated from fish mariculture environments in Cat Ba Island, Vietnam.

Background: Vibrio parahaemolyticus is a major foodborne pathogen in aquatic animals and a threat to human health worldwide. This study investigated the prevalence, antimicrobial resistance, antimicrobial resistance genes (ARGs), and biofilm formation of V. parahaemolyticus strains isolated from fish mariculture environments in Cat Ba Island, Vietnam.

Copper Tolerance of Novel sp. Yeast Isolated from Gold Mining Ore in Gia Lai, Vietnam.

In this study, twenty-five yeast strains were isolated from soil samples collected in the gold mining ore in Gia Lai, Vietnam. Among them, one isolate named GL1 could highly tolerate Cu up to 10 mM, and the isolates could also grow in a wide range of pH (3-7), and temperature (10-40 °C). Dried biomass of GL1 was able to remove Cu effectively up to 90.

The trilogy between CEO overpower, green credit, and core competence: Evidence from commercial banks in Vietnam.

This paper investigates the interconnection between Chief Executive Officer (CEO) power, green credit, and core competence of commercial banks in Vietnam. Our data sample consists of 373 annual observations from 2010 to 2021. We employ a dynamic system Generalized Method of Moments to analyze an unbalanced panel comprised of 373 annual observations from 2010 to 2021.

Adaptive Accumulation of Plantar Pressure for Ambulatory Activity Recognition and Pedestrian Identification.

In this paper, we propose a novel method for ambulatory activity recognition and pedestrian identification based on temporally adaptive weighting accumulation-based features extracted from categorical plantar pressure. The method relies on three pressure-related features, which are calculated by accumulating the pressure of the standing foot in each step over three different temporal weighting forms. In addition, we consider a feature reflecting the pressure variation.

Pre-Clinical Activity of Amino-Alcohol Dimeric Naphthoquinones as Potential Therapeutics for Acute Myeloid Leukemia.

Background: The clinical outcomes of patients with Acute Myeloid Leukemia (AML) remain unsatisfactory. Therefore the development of more efficacious and better-tolerated therapy for AML is critical. We have previously reported anti-leukemic activity of synthetic halohydroxyl dimeric naphthoquinones (BiQ) and aziridinyl BiQ.

Discovering Biomass Structural Determinants Defining the Properties of Plant-Derived Renewable Carbon Fiber.

Traditional lignocellulosic feedstock research has focused on biomass characteristics essential for improving saccharification efficiency, yet the key biomass features underlying high-quality renewable lignin materials remain unknown. Nevertheless, modern biorefinery cannot achieve sustainability and cost-effectiveness unless the lignin stream can be valorized. We hereby addressed these scientific gaps by investigating biomass characteristics defining lignin-based carbon materials properties.

Micellar growth and network formation in acidic solutions of a sulfobetaine zwitterionic surfactant triggered by an inorganic salt.

Micellization (formation of wormlike structures) of 3-(N-erucamidopropyl-N,N-dimethyl ammonium)propane sulfonate (EDAS) in the presence of an inorganic salt, iron chloride (FeCl3), in acidic conditions is studied using static and dynamic rheological measurements and small-angle X-ray scattering (SAXS). Infrared spectroscopy, single crystal X-ray, and UV-visible spectroscopy are used to further investigate the mechanisms of viscosity and elasticity and the enhancement and formation of an elastic gel-like solution induced by Fe3+ in HCl. The nature of the interaction is characterized to be hydrogen bonding between the amide groups of EDAS and coordinated water in trans-[FeCl2(H2O)4]Cl structure.

Non-Solvent Fractionation of Lignin Enhances Carbon Fiber Performance.

Even though lignin carbon fiber has been sought after for several decades, the poor mechanical performance remains to be a major barrier for commercial applications. The low mechanical performance is attributed to the heterogeneity of lignin polymer. Recent advances in fractionation technologies showed the great potential to reduce lignin heterogeneity, but current fractionation methods often depend on costly chemicals and materials such as enzymes, organic solvents, membranes, and dialysis tubes.

Synthesis, characterization and antineoplastic activity of bis-aziridinyl dimeric naphthoquinone - A novel class of compounds with potent activity against acute myeloid leukemia cells.

The synthesis, characterization and antileukemic activity of rationally designed amino dimeric naphthoquinone (BiQ) possessing aziridine as alkylating moiety is described. Bis-aziridinyl BiQ decreased proliferation of acute myeloid leukemia (AML) cell lines and primary cells from patients, and exhibited potent (nanomolar) inhibition of colony formation and overall cell survival in AML cells. Effective production of reactive oxygen species (ROS) and double stranded DNA breaks (DSB) induced by bis-aziridinyl BiQ is reported.

Step-Detection and Adaptive Step-Length Estimation for Pedestrian Dead-Reckoning at Various Walking Speeds Using a Smartphone.

We propose a walking distance estimation method based on an adaptive step-length estimator at various walking speeds using a smartphone. First, we apply a fast Fourier transform (FFT)-based smoother on the acceleration data collected by the smartphone to remove the interference signals. Then, we analyze these data using a set of step-detection rules in order to detect walking steps.

Stride Counting in Human Walking and Walking Distance Estimation Using Insole Sensors.

This paper proposes a novel method of estimating walking distance based on a precise counting of walking strides using insole sensors. We use an inertial triaxial accelerometer and eight pressure sensors installed in the insole of a shoe to record walkers' movement data. The data is then transmitted to a smartphone to filter out noise and determine stance and swing phases.
