Experimental robustness of Fourier ptychography phase retrieval algorithms
(OSA, 2015-12)Fourier ptychography is a new computational microscopy technique that provides gigapixel-scale intensity and phase images with both wide field-of-view and high resolution. By capturing a stack of low-resolution images under ... -
Computational illumination for high-speed in vitro Fourier ptychographic microscopy
(2015-10-20)We demonstrate a new computational illumination technique that achieves large space-bandwidth-time product, for quantitative phase imaging of unstained live samples in vitro. Microscope lenses can have either large field ... -
Hamiltonian and phase-space representation of spatial solitons
(ELSEVIER SCIENCE BV, 2014-05-01)We use Hamiltonian ray tracing and phase–space representation to describe the propagation of a single spatial soliton and soliton collisions in a Kerr nonlinear medium. Hamiltonian ray tracing is applied using the ... -
Experimental compressive phase space tomography
(2012-04-09)Phase space tomography estimates correlation functions entirely from snapshots in the evolution of the wave function along a time or space variable. In contrast, traditional interferometric methods require measurement of ... -
Compressive x-ray phase tomography based on the transport of intensity equation
(2013-09-01)We develop and implement a compressive reconstruction method for tomographic recovery of refractive index distribution for weakly attenuating objects in a microfocus x-ray system. This is achieved through the development ... -

Minimizing the residual topography effect on interferograms to improve DInSAR results: estimating land subsidence in Port-Said City, Egypt
(MDPI AG, 2017-07-21)The accurate detection of land subsidence rates in urban areas is important to identify damage-prone areas and provide decision-makers with useful information. Meanwhile, no precise measurements of land subsidence have ... -
No equity, no triple aim: strategic proposals to advance health equity in a volatile policy environment
Health professionals, including social workers, community health workers, public health workers, and licensed health care providers, share common interests and responsibilities in promoting health equity and improving ... -
Food insecurity in veteran households: findings from nationally representative data
(2016-07)OBJECTIVE: The present study is the first to use nationally representative data to compare rates of food insecurity among households with veterans of the US Armed Forces and non-veteran households. DESIGN: We used data ... -
Examining mortality among formerly homeless adults enrolled in Housing First: An observational study
(2015-12)BACKGROUND: Adults who experience prolonged homelessness have mortality rates 3 to 4 times that of the general population. Housing First (HF) is an evidence-based practice that effectively ends chronic homelessness, yet ... -
Predictors of homelessness among families and single adults after exit from homelessness prevention and rapid re-housing programs: evidence from the Department of Veterans Affairs Supportive Services for Veteran Families Program
(2016-01-02)This article assesses the extent and predictors of homelessness among Veterans (both Veterans in families with children and single adults Veterans) exiting the Supportive Services for Veteran Families (SSVF) program, ... -
Unsheltered homelessness among veterans: correlates and profiles
(2016-02)We identified correlates of unsheltered status among Veterans experiencing homelessness and describe d distinct subgroups within the unsheltered homeless Veteran population using data from a screening instrument for ... -
A comparison of substance use stigma and health stigma in a population of veterans with co-occurring mental health and substance use disorders
(The Haworth Medical Press, 2016)OBJECTIVE: This pilot study examined whether substance use or mental illness was more stigmatizing among individuals with co-occurring mental health and substance abuse problems. METHODS: This study included 48 individuals ... -
Characteristics and likelihood of ongoing homelessness among unsheltered veterans
(2016)INTRODUCTION: Unsheltered homelessness is an important phenomenon yet difficult to study due to lack of data. The Veterans Health Administration administers a universal homelessness screener, which identifies housing status ... -
Energy-efficient and high-performance lock speculation hardware for embedded multicore systems
(ASSOC COMPUTING MACHINERY, 2015-05-01)Embedded systems are becoming increasingly common in everyday life and like their general-purpose counterparts, they have shifted towards shared memory multicore architectures. However, they are much more resource constrained, ... -
Cost of health care utilization among homeless frequent emergency department users
(2017-05)Research demonstrates that homelessness is associated with frequent use of emergency department (ED) services, yet prior studies have not adequately examined the relationship between frequent ED use and utilization of ... -
Comparing the utilization and cost of health services between veterans experiencing brief and ongoing episodes of housing instability
(2017-02)Housing instability is associated with costly patterns of health and behavioral health service use. However, little prior research has examined patterns of service use associated with higher costs among those experiencing ... -
Pathways into homelessness among post 9/11 era veterans
(Educational Publishing Foundation, 2017)Despite the scale of veteran homelessness and government–community initiatives to end homelessness among veterans, few studies have featured individual veteran accounts of experiencing homelessness. Here we track veterans’ ... -
