A pair of DUF538 domain‐containing proteins modulates plant growth and trichome development through the transcriptional regulation of GLABRA1 in Arabidopsis thaliana

Chao‐Yuan Yu, Oshin Sharma, Phong H.T. Nguyen, Chynthia D. Hartono, more

The Plant Journal > 108 > 4 > 992 - 1004

SMALLER TRICHOMES WITH VARIABLE BRANCHES (SVB) is an emerging plant growth regulator in trichome development, endoplasmic reticulum stress response, and phosphoinositide signaling, and belongs to the land plant‐specific DUF538 domain‐containing protein family. Despite its multifaceted roles, the functions of this protein family are poorly understood in plant growth and development. Here, we report...

An approach to calculating large strain accumulation for discrete element simulations of granular media

Nhu H.T. Nguyen, Ha H. Bui, Giang D. Nguyen

International Journal for Numerical and Analytical Methods in Geomechanics > 44 > 11 > 1525 - 1547

For research on granular materials, establishing a method to calculate continuum strain from particle displacements is necessary for understanding the material behaviour at macro‐level and developing continuum constitutive models. Existing methods are generally based on constructing a mesh or background grid to calculate strain from particle motions. These methods offer rigorous ways to measure strain...

Journal of Applied Microbiology > 129 > 1 > 51 - 62

Aims We investigated the potential cooperative effects of carotenoid‐producing Bacillus aquimaris SH6 and nonpigmented Bacillus subtilis SH23 on white‐leg shrimp growth and health. Methods and Results SH6, SH23 and a combination of both spores (1 × 10⁶ CFU per g pellet) were administered in shrimp. The growth rate (2·36% day⁻¹), red‐colour score (25) and astaxanthin concentration (3·5 µg g⁻¹ shrimp)...

Recycling of food waste for fuel precursors using an integrated bio-refinery approach

O.P. Karthikeyan, H.T. Nguyen Hao, Ali Razaghi, Kirsten Heimann

Bioresource Technology > 2018 > 248 > PA > 194-198

The main aim was to integrate FW-recycling with cultivation of Rhodotorula glutinis and anaerobic digestion (AD) for bio-energy and -fuel recovery. Mixed FW was mechanically macerated (Pcon) and hydrolysed (at 250gL⁻¹ water) via chemical (Ch), thermal (Th) and TCh (combined Ch and Th) treatments. Cleared hydrolysates from individual pre-treatment processes were used as culture medium for cultivation...

A cohesive damage-plasticity model for DEM and its application for numerical investigation of soft rock fracture properties

Nhu H.T. Nguyen, Ha H. Bui, Giang D. Nguyen, Jayantha Kodikara

International Journal of Plasticity > 2017 > 98 > C > 175-196

The failure of soft rocks is highly concerned in both research and practice due to the vulnerability of materials and its involvement in a wide range of foundation and mine collapses. Different methods have been suggested to study the fracture characteristics of soft rocks. In this study, a discrete-based modelling method is proposed, as an alternative to existing continuum methods, to analyse the...

L. Ye, A. Argha, B.G. Celler, H.T. Nguyen, more

Sensors and Actuators A: Physical > 2017 > 266 > C > 294-307

In this paper, an online auto-calibration method for MicroElectroMechanical Systems (MEMS) triaxial accelerometer (TA) is proposed, which can simultaneously identify the time-dependent model structure and its parameters during the changes of the operating environment. Firstly, the model as well as its associated cost function is linearized by a new proposed linearization approach. Then, exploiting...

Phu H. Dang, Hanh H.T. Nguyen, Hien T.T. Truong, Truong N.V. Do, more

Tetrahedron Letters > 2017 > 58 > 40 > 3897-3900

Two new taxanes, named wallitaxane G (1) and H (2), were isolated from the roots of Taxus wallichiana (Taxaceae), together with nine known compounds (3−11). Their structures were elucidated on the basis of NMR spectroscopic analysis and the relative configurations of 1 and 2 were determined based on NOESY data. Wallitaxane H (2) showed the most potent α-glucosidase inhibitory activity, with an IC₅₀...

A thermodynamics-based cohesive model for discrete element modelling of fracture in cemented materials

Nhu H.T. Nguyen, Ha H. Bui, Giang D. Nguyen, J. Kodikara, more

International Journal of Solids and Structures > 2017 > 117 > C > 159-176

In this research, a discrete modelling approach employing a new cohesive model is proposed to investigate the failure response of cemented materials. A cohesive model considering mixed-mode fracture is developed based on a generic thermodynamic framework for coupling damage mechanics and plasticity theory. Discrete Element Method (DEM), a well-known computational method for simulating large deformation...

Lineage Specification from Prostate Progenitor Cells Requires Gata3-Dependent Mitotic Spindle Orientation

Maxwell E.R. Shafer, Alana H.T. Nguyen, Mathieu Tremblay, Sophie Viala, more

Stem Cell Reports > 2017 > 8 > 4 > 1018-1031

During prostate development, basal and luminal cell lineages are generated through symmetric and asymmetric divisions of bipotent basal cells. However, the extent to which spindle orientation controls division symmetry or cell fate, and the upstream factors regulating this process, are still elusive. We report that GATA3 is expressed in both prostate basal progenitor and luminal cells and that loss...

FE simulation of the influence of plastic strain on hydrogen distribution during an U-bend test

Y. Charles, H.T. Nguyen, M. Gaspérini

International Journal of Mechanical Sciences > 2017 > 120 > C > 214-224

During an U-bend test, used for the macroscopic characterization of hydrogen embrittlement of thin sheets, a flat metallic strip is first given an U-shape and then submitted to hydrogen cathodic charging. Finite element simulations of this test have been performed for iron, based on the hydrogen transport equation accounting for diffusion and trapping. Focus is made on the influence of the geometric...

Ali Razaghi, O.P. Karthikeyan, H.T. Nguyen Hao, Kirsten Heimann

Bioresource Technology > 2016 > 217 > C > 100-103

This study investigated hydrolysis approaches for cultivation of the oleaginous red yeast Rhodotorula glutinis for biodiesel production, whilst utilising the residual solids (RS) for biogas production. Macerated fruit and vegetable waste (FVW) (24h–4°C-leachate served as the control, Pcon) was hydrolysed chemically (Chem), thermally (Therm) and using a combined thermo-chemical treatment (T-Chem)....

CaMKII and at least two unidentified kinases phosphorylate regulatory light chain in non-contracting cardiomyocytes

Hilde Eikemo, Lise Román Moltzau, Cam H.T. Nguyen, Finn Olav Levy, more

Biochemical and Biophysical Research Communications > 2016 > 477 > 1 > 14-19

In cardiac tissue, regulatory light chain (RLC, myosin light chain 2) phosphorylation (Ser¹⁵) leads to modulation of muscle contraction through Ca²⁺-sensitization. To elucidate which kinases that are involved in the basal (diastolic phase) RLC phosphorylation, we studied non-contracting adult rat cardiomyocytes. RLC kinase activities in situ were unmasked by maximally inhibiting myosin light chain...

V.M. Abazov, B. Abbott, B.S. Acharya, M. Adams, more

Physics Letters B > 2016 > 757 > C > 199-206

We present a measurement of the correlation between the spins of t and t¯ quarks produced in proton–antiproton collisions at the Tevatron Collider at a center-of-mass energy of 1.96 TeV. We apply a matrix element technique to dilepton and single-lepton+jets final states in data accumulated with the D0 detector that correspond to an integrated luminosity of 9.7 fb−1. The measured value of the correlation...

H.T. Nguyen, N.H. Yu, S.J. Jeon, H.W. Lee, more

Letters in Applied Microbiology > 62 > 6 > 488 - 493

The emergence of pathogenic bacterial strains resistant to agrochemicals and the increasing demand for organic foods have led to the discovery of new antibacterial metabolites that can be used either directly or as a lead molecule for development of synthetic bactericides. During the screening of antibacterial fungal cultures, we found that one fungal strain, Aspergillus persii EML‐HPB1‐11, showed...

CaMKII in addition to MLCK contributes to phosphorylation of regulatory light chain in cardiomyocytes

Hilde Eikemo, Lise Román Moltzau, Rizwan I. Hussain, Cam H.T. Nguyen, more

Biochemical and Biophysical Research Communications > 2016 > 471 > 1 > 219-225

The aim was to identify kinase activities involved in the phosphorylation of regulatory light chain (RLC) in situ in cardiomyocytes. In electrically stimulated rat cardiomyocytes, phosphatase inhibition by calyculin A unmasked kinase activities evoking an increase of phosphorylated RLC (P-RLC) from about 16% to about 80% after 80 min. The phosphorylation rate in cardiomyocytes was reduced by about...
