Andrea DelMastro

Since joining the Department of Surgery in 2001 as an administrative assistant in the Division of Transplant Surgery, Andrea DelMastro has moved to our 1300 Wolf Street Office on the Methodist Campus. Born and raised in South Philly, she has returned and served as the Department’s practice manager there for the past five years. At Methodist, Andrea oversees day-to-day operations of 14 providers and a team of registrars, medical assistants and nurse practitioners. The practice includes several specialties within the Department of Surgery: Bariatric, Breast, Colorectal, General, Thoracic and Vascular Surgery & Vascular Medicine. The services provided there include more than just surgical consultations, as several other outpatient services are offered, including vascular ultrasound, minimally invasive vein closure, and wound care. During the last few years she has been active at both campuses taking on a number of departmental projects: she is currently the Department’s lead for the JeffConnect telehealth program and serves as a ‘super user’ for the EPIC Electronic Health Record implementation. Another of DelMastro’s long-term projects is contributing to the Methodist Hospital Division’s Surgery White Paper. The purpose of the ongoing initiative: to identify ways to improve both patient experience and overall surgical patient throughput at Methodist. To date, such improvements have included adding a room for private family surgical consultations and staffing a patient registrar. She appreciates the diverse challenges of her work: “Every day is different,” she says. “I juggle clinic hours, department projects, as well as the unique needs of staff and patients that come up daily.” DelMastro strives to make sure her employees are engaged, as she believes that “makes all the difference in patient care.” Above all, Andrea values being part of the Methodist community: “I love that I get to work in an office where I know the majority of my patients from the neighborhood. It’s world-class care – with a real hometown feel.

Who is Andrea Yates? A Short Story About Insanity

On June 20, 2001, Andrea Yates drowned her four children in a bathtub. At Andrea’s trial, in Harris County, Texas, the prosecution’s star expert, Patrick Dietz, appeared particularly adept at persuading the jury to accept the prosecution’s assertion that Andrea was sane and acting intentionally when she killed her children. This Article analyzes the problematic aspects of Dietz\u27s testimony in an effort to contribute some balance to the Andrea Yates story. Despite the long history of expert witnesses in criminal trials, the justice system should question the fairness and efficacy of such an unregulated storytelling process. Part I of this Article briefly discusses Andrea\u27s life up to her marriage as well as the outcome of her trial. Part II provides an overview of the insanity defense and the strict Texas insanity standard. Part III examines Dietz\u27s background, his reputation, and his psychiatric philosophy, in addition to his proclivity to testify for the prosecution. Part IV describes Andrea\u27s history of mental illness, especially her postpartum psychosis that started with the birth of her first child and ended with a severe psychotic episode. Part V focuses on Dietz\u27s testimony in the Yates trial, beginning with his pre-trial interview with Andrea and ending with an analysis of his conclusions. The discussion emphasizes the speculative nature of many of Dietz\u27s statements and their lack of connection to Andrea\u27s history of mental illness. Part VI presents the other perspectives and experts in the Yates case, and considers how the case might have reached a different result with a more consistent defense strategy or a less rigid insanity standard

A Method Based on Total Variation for Network Modularity Optimization using the MBO Scheme

The study of network structure is pervasive in sociology, biology, computer science, and many other disciplines. One of the most important areas of network science is the algorithmic detection of cohesive groups of nodes called "communities". One popular approach to find communities is to maximize a quality function known as {\em modularity} to achieve some sort of optimal clustering of nodes. In this paper, we interpret the modularity function from a novel perspective: we reformulate modularity optimization as a minimization problem of an energy functional that consists of a total variation term and an $\ell_2$ balance term. By employing numerical techniques from image processing and $\ell_1$ compressive sensing -- such as convex splitting and the Merriman-Bence-Osher (MBO) scheme -- we develop a variational algorithm for the minimization problem. We present our computational results using both synthetic benchmark networks and real data.Comment: 23 page

V605 Aquilae: a born again star, a nova or both?

V605 Aquilae is today widely assumed to have been the result of a final helium shell flash occurring on a single post-asymptotic giant branch star. The fact that the outbursting star is in the middle of an old planetary nebula and that the ejecta associated with the outburst is hydrogen deficient supports this diagnosis. However, the material ejected during that outburst is also extremely neon rich, suggesting that it derives from an oxygen-neon-magnesium star, as is the case in the so-called neon novae. We have therefore attempted to construct a scenario that explains all the observations of the nebula and its central star, including the ejecta abundances. We find two scenarios that have the potential to explain the observations, although neither is a perfect match. The first scenario invokes the merger of a main sequence star and a massive oxygen-neon-magnesium white dwarf. The second invokes an oxygen-neon-magnesium classical nova that takes place shortly after a final helium shell flash. The main drawback of the first scenario is the inability to determine whether the ejecta would have the observed composition and whether a merger could result in the observed hydrogen-deficient stellar abundances observed in the star today. The second scenario is based on better understood physics, but, through a population synthesis technique, we determine that its frequency of occurrence should be very low and possibly lower than what is implied by the number of observed systems. While we could not envisage a scenario that naturally explains this object, this is the second final flash star which, upon closer scrutiny, is found to have hydrogen-deficient ejecta with abnormally high neon abundances. These findings are in stark contrast with the predictions of the final helium shell flash and beg for an alternative explanation.Comment: 8 pages, 1 figures, 2 tables, accepted for MNRAS.

Near-Infrared Studies of V1280 Sco (Nova Scorpii 2007)

We present spectroscopic and photometric results of Nova V1280 Sco which was discovered in outburst in early 2007 February. The large number of spectra obtained of the object leads to one of the most extensive, near-infrared spectral studies of a classical nova. The spectra evolve from a P-Cygni phase to an emission-line phase and at a later stage is dominated by emission from the dust that formed in this nova. A detailed model is computed to identify and study characteristics of the spectral lines. Inferences from the model address the vexing question of which novae have the ability to form dust. It is demonstrated, and strikingly corroborated with observations, that the presence of lines in the early spectra of low-ionization species like Na and Mg - indicative of low temperature conditions - appear to be reliable indicators that dust will form in the ejecta. It is theoretically expected that mass loss during a nova outburst is a sustained process. Spectroscopic evidence for such a sustained mass loss, obtained by tracing the evolution of a P-Cygni feature in the Brackett gamma line, is presented here allowing a lower limit of 25-27 days to be set for the mass-loss duration. Photometric data recording the nova's extended 12 day climb to peak brightness after discovery is used to establish an early fireball expansion and also show that the ejection began well before maximum brightness. The JHK light curves indicate the nova had a fairly strong second outburst around 100 days after the first.Comment: Accepted in MNRAS. The paper contains 8 figures and 4 tables.

Self-adjoint elliptic operators with boundary conditions on not closed hypersurfaces

The abstract theory of self-adjoint extensions of symmetric operators is used to construct self-adjoint realizations of a second-order elliptic operator on $\mathbb{R}^{n}$ with linear boundary conditions on (a relatively open part of) a compact hypersurface. Our approach allows to obtain Krein-like resolvent formulas where the reference operator coincides with the "free" operator with domain $H^{2}(\mathbb{R}^{n})$; this provides an useful tool for the scattering problem from a hypersurface. Concrete examples of this construction are developed in connection with the standard boundary conditions, Dirichlet, Neumann, Robin, $\delta$ and $\delta^{\prime}$-type, assigned either on a $n-1$ dimensional compact boundary $\Gamma=\partial\Omega$ or on a relatively open part $\Sigma\subset\Gamma$. Schatten-von Neumann estimates for the difference of the powers of resolvents of the free and the perturbed operators are also proven; these give existence and completeness of the wave operators of the associated scattering systems.Comment: Final revised version, to appear in Journal of Differential Equation
