Ha, V.C. (author)This paper evaluates the behaviour and the usefulness of a 3D morphological pilot-experiment. It reports the set up and execution of a 3D wave-current physical model in more detail. Furthermore, a selection of the collected data will be compared with computational output from a 3D morphological model. The bathymetries are mainly determined by a...master thesis 2001

Ha, N.H. (author)Along 3,260-km coastline of Vietnam, there is a system of about 2,700-km sea dike. This system has an important role for the development of Vietnam. It protects densely concentrated population and industrial areas. However, in the storm season, there is usually some collapse in the sea dike system due to the strong impacts of wind wave and high...master thesis 2003

Kim, S.H. (author), Joo, C. (author), Ha, T. (author), Kim, D. (author)A is a DNA-dependent ATPase and mediates homologous recombination by first forming a filament on a single-stranded (ss) DNA. RecA binds preferentially to TGG repeat sequence, which resembles the recombination hot spot Chi (5'-GCTGGTGG-3') and is the most frequent pattern (GTG) of the codon usage in Escherichia coli. Because of the highly dynamic...journal article 2013

(author), Ha, Seungkyu (author), Jakobsson, ME (author), Sun, M (author)It is unclear that how subcellular organelles respond to external mechanical stimuli. Here, we investigated the molecular mechanisms by which mechanical force regulates Ca2+ signaling at endoplasmic reticulum (ER) in human mesenchymal stem cells. Without extracellular Ca2+, ER Ca2+ release is the source of intracellular Ca2+ oscillations induced...journal article 2015

Kim, S.H. (author), Park, J. (author), Joo, C. (author), Kim, D. (author), Ha, T. (author)RecA proteins form a long stable filament on a single-stranded DNA and catalyze strand exchange reaction. The stability of RecA filament changes dramatically with pH, yet its detailed mechanism is not known. Here, using a single molecule assay, we determined the binding and dissociation rates of RecA monomers at the filament ends at various pH....journal article 2015

(author)Terminal uridylyl transferases (TUTs) function as integral regulators of microRNA (miRNA) biogenesis. Using biochemistry, single-molecule, and deep sequencing techniques, we here investigate the mechanism by which human TUT7 (also known as ZCCHC6) recognizes and uridylates precursor miRNAs (pre-miRNAs) in the absence of Lin28. We find that the...journal article 2015

Dekker, N.H. (author), Ha, S. (author), Janissen, R. (author), Ussembayev, Y. (author), van Oene, M.M. (author), Solano Hermosilla, B.P. (author)Titanium dioxide (TiO2) is a key component of diverse optical and electronic applications that exploit its exceptional material properties. In particular, the use of TiO2 in its single-crystalline phase can offer substantial advantages over its amorphous and polycrystalline phases for existing and yet-to-be-developed applications. However, the...journal article 2016

Pieters, Mike (author), Ha, Damy (author)This report contains the design and implementation of two control systems related to an inductive power transfer system. This IPT system charges a battery at maximumefficiency and constant power using a buck converter. A linear controller has been designed around the buck converter and implemented on a FPGA tomatch impedance for maximum...bachelor thesis 2017

Ha, S. (author)This thesis describes developments in the single-molecule instrumentation, in particular optical torque wrench and DNA nanocurtains, with the goal of employing these techniques in studies of biomolecules and biomotors. Importantly, the use of single-crystal rutile titanium dioxide nanocylinders is suggested for optical torque wrench, enabling...doctoral thesis 2018

(author)Optical trapping of (sub)micron-sized particles is broadly employed in nanoscience and engineering. The materials commonly employed for these particles, however, have physical properties that limit the transfer of linear or angular momentum (or both). This reduces the magnitude of forces and torques, and the spatiotemporal resolution,...journal article 2019

(author)The ability to apply force and torque directly to micro- and nanoscale particles in optical traps has a wide range of applications. While full control of both force and torque in three dimensions has been realized using top-down fabrication of rod-shaped particles composed of birefringent crystalline materials, widespread usage of such...journal article 2020
