Experimental study on the coefficient of restitution of grain against block interfaces for natural and engineered materials

Autor: Clarence Edward Choi, C.S. Sandeep, Matthew Richard Coop, Kostas Senetakis, Charles Wang Wai Ng, Yu Wang, Desmond Ka Ho Cheung

Publikováno v: Canadian Geotechnical Journal. 58:35-48

The coefficient of restitution (COR) is an important input parameter in the numerical simulation of granular flows, as it governs the travel distance, the lateral spreading, and the design of barriers. In this study, a new custom-built micromechanica

Effects of dynamic fragmentation on the impact force exerted on rigid barrier: centrifuge modelling

Autor: Yifei Cui, Desmond Ka Ho Cheung, Clarence Edward Choi, Charles Wang Wai Ng

Publikováno v: Canadian Geotechnical Journal. 56:1215-1224

Bi-dispersity is a prerequisite for grain-size segregation, which transports the largest particles to the flow front. These large and inertial particles can fragment upon impacting a barrier. The amount of fragmentation during impact strongly influen

The Hepatic Response to the Pathogenesis of Type 2 Diabetes in a Rat Model

Autor: Li, Desmond Ka Kit

The liver plays a pivotal role in the maintenance of whole body energy homeostasis given its responsibilities in glucose, lipid and ketone body regulation. T2DM is a complex disease and the underlying mechanisms resulting in loss of hepatic energy re

Chow, JY; Comulada, WS; Gildner, JL; Desmond, KA; & Leibowitz, AA. (2018). Association between Federally Qualified Health Center usage and emergency department utilization among California's HIV-infected Medicaid beneficiaries, 2009.. AIDS care, 1-9. doi: 10.1080/09540121.2018.1524112. UCLA: Retrieved from: http://www.escholarship.org/uc/item/6mn0j0zq

Federally Qualified Health Centers (FQHCs) have long been important sources of care for publicly insured people living with HIV. FQHC users have historically used emergency departments (EDs) at a higher-than-average rate. This paper examines whether

Understanding ETS transcription factors : from ordered domains to disordered sequences

Autor: Lau, Desmond Ka Wing

ETS (E26 transformation specific) transcription factors play critical roles in regulating cellular growth, development and differentiation. They share a conserved ETS domain that interacts with specific DNA sequences and a subset of ETS proteins also

The replication protein A function of HIN200 family protein is mediated by complementation of PAAD and HIN200 domains

Autor: Lau, Desmond Ka Wing

Our discovery of the death domain PAAD shows not only its involvement in cell death but in other biological processes. For example, we demonstrated a DNA repair function similar to Replication Protein A for the PAAD family member IFI16 (Interferon-In
