Abstract PR622 (2016)

Background & Objectives: A patient’s health status often determines whether surgery is recommended for cancer therapy. The risk of complications may outweigh the perceived benefit. Consequently, measures that predict surgical outcomes may be helpful in determining whether or not to operate. Materials & Methods: We retrospectively apply four mortality predictors to 62,763 adult surgical cancer patients from the University of Texas MD Anderson Cancer Center during January 2007 - March 2014. We use the first surgery for each patient that is over 60 minutes in duration and compare the following indexes: Charlson Comorbidity Index1 as implemented by Deyo et al.2; Dalton’s Risk Quantification Index (RQI)3; Sessler’s Risk Stratification Index (RSI)4 and the Surgical Apgar Score5. We implement each metric as described by the authors and evaluate each score’s ability to predict 30-day mortality using logistic regression, randomly selecting two-thirds of the cases for learning the model and using the remaining cases for evaluation. We report the C-Statistic for each metric in isolation and in combination with the other measures. Results: We obtain individual C-Statistics from 0.639 to 0.784 and a combined C-Statistic of 0.817. The least predictive index is the RQI and the most predictive is the RSI.Conclusion: Despite not being designed specifically for cancer patients, or even necessarily for 30-day mortality, these metrics provide accurate predictions for our patient body. Furthermore, by combining the scores together, we are able to improve predictions, as each index is based on a different set of patient characteristics. RQI was the least useful metric, contributing only 0.01 to the combined C-Statistic. These indexes can be used to calculate and communicate the likelihood of 30-day mortality and may aid in clinical decision-making. References: 1. Charlson ME, et al.

Molecular epidemiology of catheter-associated bacteriuria in nursing home patients (1994)

Urine samples from 19 nursing home patients with long-term urinary catheters were cultured every 3 months for 18 months. Providencia stuartii, present in 74% of the elderly and in 59% of urine specimens, was the most frequently isolated bacteria. The persistence of P. stuartii was significantly higher among females than among males. In order to study the epidemiology of bacteriuria in this nursing home, bacteria were characterized by biochemical tests, antibiotic susceptibility pattern, and restriction fragment length polymorphism (RFLP) analysis. The antibiotic susceptibility pattern indicated that each patient had two to three different strains of P. stuartii during the 18 months of follow-up. In contrast, the RFLP analysis revealed that a specific strain had persisted in the urinary tract of the patient during the entire follow-up period. According to the biochemical profile, 74% of the patients had the same bacteria in urine cultures, pointing to a common source of transmission. RFLP analysis, however, demonstrated different patterns of RFLP, suggesting concomitant multiple sources of infection.
Self-consistent field theory of multiply branched block copolymer melts (2005)

We present a numerical algorithm to evaluate the self-consistent field theory for melts composed of block copolymers with multiply branched architecture. We present results for the case of branched copolymers with doubly functional groups for multiple-branching generations. We discuss the stability of the cubic phase of spherical micelles, the A15 phase, as a consequence of the tendency of the AB interfaces to conform to the polyhedral environment of the Voronoi cell of the micelle lattice.
Effect of Plant Age, Maturity Group, and the Environment on Disease Progress of Sudden Death Syndrome of Soybean (1995)

Disease progress of sudden death syndrome (SDS) of soybean, caused by Fusarium solani, was determined in a standard susceptible cultivar, Lee 74, planted uniformly throughout the test site and in 42 soybean cultivars representing maturity groups (MG) IV-VIII, 1986-1989. Disease severity was assessed weekly from the middle of July through the first of October using a visual rating scale of percent leaf area exhibiting foliar symptoms of SDS. The disease ratings were used to calculate the absolute infection rate (dy/dt) for each cultivar at each rating time and the area under the disease progress curve (AUDPC). In Lee 74, SDS progressed in two phases: an initial rapid increase in disease to about 35% leaf area affected and a slower increase after that point. This two-phase disease progress curve was fit by a segmented model using two exponential equations. The fits of these equations were highly significant (P 1%/day or, if lower than 1%/day, the highest dy/dt attained). DAP and dy/dt were significantly (P < 0.0001) related to AUDPC (R = −0.58 and R = 0.38, respectively). Cultivars susceptible to race 6 of the soybean cyst nematode (SCN), Heterodera glycines, the predominate race in the field, developed SDS 10 days earlier and had significantly higher levels of disease than cultivars resistant to race 6 of SCN. The earliest increases in SDS occurred between 71 and 77 DAP in 1986, 69 and 74 DAP in 1987, and 75 and 83 DAP in 1988 for most MGs. Accumulated heat for these periods was 910-942, 852-916, and 857-963 degree-days in 1986, 1987, and 1988, respectively. In 1987, three cultivars in MG VII and VIII had large increases 52 DAP after 608 degree-days. In general, however, disease increased at the same time across MGs, but at no specific reproductive stage
Understanding the impact of network infrastructure changes using large-scale measurement platforms (2017)

A number of large-scale network measurement platforms have emerged in the last few years. These platforms have deployed thousands of measurement probes at strategic locations within the access and backbone networks and at residential gateways. The primary goal of these efforts is typically to measure the performance of broadband access networks and to help regulators sketch better policy decisions. In this dissertation we expand the goal further by using large-scale measurement platforms to understand the impact of network infrastructure changes. We deploy probes at the edge of the network to measure IPv6 performance and to dissect last-mile latency characteristics of access networks.
Experimental analysis of elemental factors controlling the life of PAFCs (1996)

Since 1991, 5MW-class and 1MW-class PAFC power plants have been demonstrated with the objective of accelerating development and commercialization by the Phosphoric Acid Fuel Cell Technology Research Association (PAFC-TRA) jointly with NEDO as one of MITI`s fuel cell programs. As a complimentary research project to the demonstration project, the mechanism and rate of deterioration of the cells and stacks have been studied from 1995 FY, with the objective of establishing an estimation method for the service life-time of the cell stacks. Our work has been performed in the Basic Research Project, as part of that project on PAFCs, with the cooperation of Yamanashi University supported by the Ministry of Education, Science and Culture, PAFC-TRA supported by NEDO and three PAFC makers. We have selected the following four subjects as the essential factors relating to the life-time, after a year-long study of the literature and the accumulation of a large number of data as to the practical operations of the cells, cell stacks and plants of PAFCs; i.e., (1) Mechanism of the degradation of electrocatalysts and the effect of the degradation on the electrode performances. (2) Effect of the electrolyte fill-level on the electrode performances. (3) Corrosion of cell constructing materials and the effect of the corrosion on the electrode performances. (4) The rate and mechanism of electrolyte loss under various operating conditions of a model cell. The paper briefly introduces the interim results which have been found on the above subjects at this time.
Analysis and Control of the Output Instantaneous Power for Three Phase PWM Boost Rectifier Under Unbalanced Supply Voltage Conditions (2006)

This paper proposes a new method to analyze the output instantaneous power of the three phase PWM boost rectifier under unbalanced supply voltage conditions. An analytical expression for the output instantaneous power has been derived and presented, which provides the link between the output dc linkage voltage and the instantaneous output power. Based on the mathematical model of the three phase PWM rectifier in the rotating synchronous frame, the physical concept of the output instantaneous power has been explained from the analytical point of view. A direct relationship between the dc link voltage ripples and the second harmonic component in the instantaneous output power has been derived. A simple cascaded PI control scheme has been developed for the dc output voltage control. The controller ensures that the dc link voltage is maintained constant and the supply side power factor is kept close to unity under the unbalanced supply voltage operating conditions. Simulation and experimental test results are provided on a 1.6 kVA laboratory based PWM rectifier to validate the proposed analysis and control scheme
Quantitative Analysis of the Initial Restructuring Step of Nanostructured FeSn<sub>2</sub>-Based Anodes for Li-Ion Batteries (2013)

The first discharge of a nanostructured FeSn2 based negative electrode for Li-ion batteries has been studied by combining operando 119Sn Mössbauer spectroscopy and ex situ magnetic measurements. A modified Swagelok-type cell has been designed to perform in situ Mössbauer measurements, which allowed us to quantitatively follow the first discharge. The electrochemical mechanism consists in a conversion reaction that transforms FeSn2 into Li7Sn2. The Mössbauer spectrum at the end of the first discharge has been analyzed from first principles calculations of the Mössbauer parameters. The observed differences with bulk Li7Sn2 have been explained by the small size of the electrochemically formed particles. The magnetic measurements of the electrode material at the end of the discharge show the existence of rather pure superparamagnetic iron nanoparticles with an average diameter in the range 2–3 nm as evaluated from three different methods. The electrode saturation magnetization increases during the discharge, due to the increasing number of formed iron nanoparticles, but unexpected two-step variations were observed. They are interpreted by changes of the FeSn2 magnetization caused by interactions with iron nanoparticles.
Resolution+attention+nesting=interpretation (2003)

In this study, a knowledge for subsequent interpretation is represented as a descriptive structure (D-structure) in a fuzzy linguistic representation space (FLR-space). Any subset of interest within the D-structure is considered as a D-state to be controlled by an interpretation-based production system. Both nodes and relations are fuzzy valued. D-structure is a nested structure. This approach is applied to the problem of motion control.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Neurobehavioral Performance of Residents After Heavy Night Call vs After Alcohol Ingestion (2005)

The issue of work-related sleep loss and consequent fatigue in medical residents continues to cause concern. Some, but not all, studies point to postcall deficits in performance. In this prospective study of 34 pediatric residents, postcall performance was compared during a heavy call rotation (defined as every fourth or fifth night) with light call, light call combined with a blood alcohol concentration of 0.04 gm% to 0.05 gm% per 100 mL, and heavy call with a placebo. The study group included 18 women and 16 men with a mean age of 29 years who worked at an academic medical center. An hour-long test battery was administered during the final week of a light call rotation (nonpostcall); in the final week of a heavy call rotation (postcall); and after alcohol (in the light call group) or placebo (in the heavy call group). Each test session ended with a self-assessment of performance. Outcome measures included the Stanford Sleepiness Scale, a visual analog scale, the Psychomotor Vigilance Task, the Continuance Performance Test, and a simulated driving task. Heavy and light call rotations averaged 90 and 44 hours per week, respectively. Nocturnal sleep averaged approximately 7–1/2 hours during light call and 6–1/4 hours during heavy call. Compared with light call, heavy call reaction times were 7% slower, commission errors were 40% higher, and performance on the driving simulator was substantially poorer. One driving parameter, speed variability, was greater in heavy call with placebo than in light call with alcohol. There were, however, no significant group differences in reaction time, omission errors, lapses, or off-road riving. Self-assessments correlated with actual performance in heavy call residents with respect to commission errors, lane variability, and speed variability, but not reaction time. In both heavy call groups, more participants rated their performance on the Psychomotor Vigilance Task to be poor. Performance on the Continuous Performance Test did not relate to training year. Residents on heavy call or light call with alcohol made more commission errors on this test, and self-ratings showed the same trend. Far more heavy call residents than light call residents rated their simulated driving performance as poor or worse. Using a variety of performance tests, medical residents in this study were about as impaired postcall after 4 weeks on a heavy call rotation as were those on light call who had blood alcohol levels of 0.04 to 0.05 gm%. Residents must be aware of postcall performance impairment and the consequent risk to both themselves and their patients. Sleepy residents may not recognize that they are impaired. Residency programs should include discussions of sleep loss, fatigue, and effective countermeasures. Residency programs might consider adopting such measures as alternative call schedules and postcall quarters in which residents can nap.
Idiopathic Splenic Artery Pseudoaneurysm Rupture as an Uncommon Cause of Hemorrhagic Shock (2015)

Splenic artery pseudoaneurysms are infrequently encountered but critical to recognize. Limited literature to date describes associations with pancreatitis, trauma, and rarely peptic ulcer disease. Hemorrhage and abdominal pain are the most common manifestations. There is typically overt gastrointestinal blood loss but bleeding can also extend into the peritoneum, retroperitoneum, adjacent organs, or even a pseudocyst. Most patients with ruptured splenic artery pseudoaneurysms present with hemodynamic instability. Here, we describe a patient recovering from acute illness in the intensive care unit but with otherwise no obvious risk factors or precipitants for visceral pseudoaneurysm. He presented with acute onset altered mental status, nausea, and worsening back and abdominal pain and was found to be in hypovolemic shock. The patient was urgently stabilized until more detailed imaging could be performed, which ultimately revealed the source of blood loss and explained his rapid decompensation. He was successfully treated with arterial coiling and embolization. Thus, we herein emphasize the importance of prompt recognition of hemorrhagic shock and of aggressive hemodynamic stabilization, as well as a focused diagnostic approach to this problem with specific treatment for splenic artery pseudoaneurysm. Finally, we recommend that multidisciplinary management should be the standard approach in all patients with splenic artery pseudoaneurysm.
Linear Optimization over a Polymatroid with Side Constraints -- Scheduling Queues and Minimizing Submodular Functions (2008)

Two seemingly unrelated problems, scheduling a multiclass queueing system and minimizing a submodular function, share a rather deep connection via the polymatroid that is characterized by a submodular set function on the one hand and represents the performance polytope of the queueing system on the other hand. We first develop what we call a {\it grouping} algorithm that solves the queueing scheduling problem under side constraints, with a computational effort of $O(n^3LP(n))$, $n$ being the number of job classes, and LP(n) being the computational efforts of solving a linear program with no more than $n$ variables and $n$ constraints. The algorithm organizes the job classes into groups, and identifies the optimal policy to be a priority rule across the groups and a randomized rule within each group (to enforce the side constraints). We then apply the grouping algorithm to the submodular function minimization, mapping the latter to a queueing scheduling problem with side constraints. %Each time the algorithm is applied, it identifies a subset; and We show the minimizing subset can be identified by applying the grouping algorithm $n$ times. Hence, this results in a algorithm that minimizes a submodular function with an effort of $O(n^4LP(n))$.
Time-varying channel characterization based on SVM under the impulsive noise presence (2010)

The purpose of this work is to present an off-line technique for characterization of time-varying power line communications channels in the presence of additive impulsive noise when they are used for broadband data transmission. We propose and analyze a channel estimation technique based on Support Vector Machine (SVM). Simulation results reveal that the proposed method is more robust to impulsive noise and has better convergence rate for time-varying channels when compared to classic techniques like least squares (LS).

Popeye domain containing gene 2 (Popdc2) is a myocyte‐specific differentiation marker during chick heart development (2004)

The Popeye domain containing (popdc) genes constitute a novel gene family encoding proteins of the plasma membrane in muscle cells, with three N-terminal transmembrane domains and a cytoplasmic carboxy terminus. In vertebrates, three members of the Popdc gene family have been described. However, in the chick system only two cDNAs, Popdc1 and Popdc3, have been cloned previously. By screening a chick expressed sequence tag database, we report here the identification of five alternatively spliced chick Popdc2 cDNAs with different carboxy termini. Northern blot analysis revealed expression of Popdc2 predominantly in the myocardium and weaker expression in skeletal muscle. By whole-mount in situ hybridization, chick Popdc2 was first detected at Hamburger and Hamilton (HH) stage 7 within the anterior part of the heart fields. In the tubular heart, atrial and ventricular precursor cells stained positively for Popdc2. Weaker expression was observed in myocardium of the outflow tract and sinus venosus. By HH stage 18, the outer curvature myocardium was strongly stained, whereas expression in myocardium of the inner curvature was negligible. Popdc2 expression was absent from the endocardium and propepicardial organ. At HH stage 36, Popdc2 expression was confined to the compact layer myocardium. In addition to the heart, Popdc2 expression was also observed in the myotome and in the muscle-forming fields of the limbs. Our results indicate that Popdc2 is highly expressed in the developing heart and may serve as a novel marker of myocardial differentiation in the chick embryo.
Linear thermal expansion measurements of lead magnesium niobate (PMN) electroceramic material for the Terrestrial Planet Finder Coronagraph (2005)

Linear thermal expansion measurements of nine samples of Lead Magnesium Niobate (PMN) electroceramic material were recently performed in support of NASA's Terrestrial Planet Finder Coronagraph (TPF-C) mission. The TPF-C mission is a visible light coronagraph designed to look at roughly 50 stars pre-selected as good candidates for possessing earth-like planets. Upon detection of an earth-like planet, TPF-C will analyze the visible-light signature of the planet's atmosphere for specific spectroscopic indicators that life may exist there. With this focus, the project's primary interest in PMN material is for use as a solid-state actuator for deformable mirrors or compensating optics. The nine test samples were machined from three distinct boules of PMN ceramic manufactured by Xinetics Inc. Thermal expansion measurements were performed in 2005 at NASA Jet Propulsion Laboratory (JPL) in their Cryogenic Dilatometer Facility. All measurements were performed in vacuum with sample temperature actively controlled over the range of 270K to 310K. Expansion and contraction of the test samples with temperature was measured using a JPL-developed interferometric system capable of sub-nanometer accuracy. Presented in this paper is a discussion of the sample configuration, test facilities, test method, data analysis, test results, and future plans.
