Depletion of gram-positive bacteria impacts hepatic biological functions during the light phase
(2019)Living organisms display internal biological rhythms, which are an evolutionarily conserved adaptation to the environment that drives their rhythmic behavioral and physiological activities. The gut microbiota has been ... -
Addressing the epistemic uncertainty in maritime accidents modelling using Bayesian network with interval probabilities
(2017)Bayesian Network (BN) is often criticized for demanding a large number of crisp/exact/precise conditional probability numbers which, due to the lack of statistics, have to be obtained through experts’ judgment. These exact ... -
Modelling multilevel interdependencies for resilience in complex organisation
(2019)This paper aims to model multilevel interdependencies in complex organisational systems and proposes application for resilience analysis. Most of the existing research studied interdependencies only at the single-level and ... -
Nanofibrous PLGA electrospun scaffolds modified with type I collagen influence hepatocyte function and support viability in vitro
(2018)A major challenge of maintaining primary hepatocytes in vitro is progressive loss of hepatocyte-specific functions, such as protein synthesis and cytochrome P450 (CYP450) catalytic activity. We developed a three-dimensional ... -
Urea-assisted one-step synthesis of cobalt ferrite impregnated ceramic membrane for sulfamethoxazole degradation via peroxymonosulfate activation
(2018)In this study, a novel CoFe2O4 nanocatalyst impregnated Al2O3 ceramic membrane was prepared via a urea-assisted one-step combustion method. The catalytic membrane was characterized by field emission scanning electron ... -
A rectifier-less ac–dc interface circuit for ambient energy harvesting from low-voltage piezoelectric transducer array
(2018)This paper presents a rectifier-less ac-dc energy harvesting circuit capable of harvesting energy from multiple low-voltage piezoelectric transducers (PETs). Synchronous electric charge extraction technique, with bidirectional ... -
Increased intracellular cyclic di-AMP levels sensitize Streptococcus gallolyticus subsp. gallolyticus to osmotic stress and reduce biofilm formation and adherence on intestinal cells
(2019)Cyclic di-AMP is a recently identified second messenger exploited by a number of Gram-positive bacteria to regulate important biological processes. Here, we studied the phenotypic alterations induced by the increased ... -
CFD analyses of the wind drags on khaya senegalensis and eugenia grandis
(2018)The drag coefficients of one mature Khaya Senegalensis tree and one Eugenia Grandis tree in Singapore were analysed using computational fluid dynamics (CFD) modelling and validated with field measurements. For the numerical ... -
Mesoporous SiO2/BiVO4/CuOx nanospheres for Z-scheme, visible light aerobic C–N coupling and dehydrogenation
(2019)In light of the growing demand to use renewable energy, we have synthesized a mesoporous bismuth vanadate-copper oxide-silica photocatalyst (SiO2/BiVO4/CuOx) to act as a chromophore in a Z-scheme system. These photocatalysts ... -
Unit commitment with AC power flow constraints for a hybrid transmission grid
(2018)A unit commitment formulation satisfying AC optimal power flow constraints models the resource optimization problem accurately, but is challenging to solve for traditional transmission systems. Integration of generation ... -
Stabilizing droop variation of converter-connected generation in autonomous microgrids with virtual inertia control
(2018)Droop scheduling plays an important role in the microgrid frequency regulation market, as the well-known proportional load sharing may be practically inapplicable in many cases of inverter-based microgrids. The drooping ... -
Octal gray-code phase unwrapping for high-speed fringe projection profilometry
(2019)The speed of a fringe projection profilometry system is of great importance for the measurement of dynamic objects. The previous quaternary gray-code phase unwrapping method uses only five patterns to recover an absolute ... -
Effects of airflow rate and supply air temperature on the airflow pattern under active chilled beam system
(2018)Effects of airflow rate and supply air temperature on the airflow pattern for Active Chilled Beams (ACB) system are investigated in this paper. The air velocity for the air jet near the ceiling are tested and recorded under ... -
Optical NP problem solver on laser-written waveguide platform
(2018)Cognitive photonic networks are researched to efficiently solve computationally hard problems. Flexible fabrication techniques for the implementation of such networks into compact and scalable chips are desirable for the ... -
Rate dependent behaviors of nickel-based microcapsules
(2018)In this work, nickel-based microcapsules with liquid core were fabricated through an electroless plating approach. The quasi-static and high speed impact behaviors of microcapsules were examined by in-house assembled setups ... -
Similarities and differences in gut microbiome composition correlate with dietary patterns of Indian and Chinese adults
(2018)The interaction between diet and gut microbiota, and ultimately their link to health, has turned into the concentration of huge research. However, this relationship still needs to be fully characterized, particularly in ... -
Multi-energy scheduling using a hybrid systems approach
(2018)This paper presents a mixed logical dynamical (MLD) approach for modelling a multi-energy system. The electrical and thermal energy streams are linked through the operation of combined cycle power plants (CCPPs). The MLD ... -
Influence of third particle on the tribological behaviors of diamond-like carbon films
(2016)Tribological mechanisms of diamond-like carbon (DLC) films in a sand-dust environment are commonly unclear due to the complicated three-body abrasion caused by sand particles. This study investigates the three-body abrasion ... -
Tailoring CO2 /CH4 separation properties of mixed-matrix membranes via combined use of two- and three-dimensional metal-organic frameworks
(2018)Mixed-matrix membranes containing both two-dimensional (ns-CuBDC) and three-dimensional (ZIF-8) metal-organic frameworks were fabricated to investigate their potential capabilities in CO2/CH4 separation. The mixed-matrix ... -
Packed bed regenerators using cascaded phase change materials : overcharging and possible solutions
(2018)In this paper, packed bed regenerators using different phase change materials cascaded in series for cold energy storage are investigated with specific focus on charging behaviour. Indeed, when one phase change material ...
