Otto schmitt’s contributions to basic and applied biomedical engineering and to the profession

Otto Schmitt was one of the early giants in biomedical engineering. Best known in engineering circles for the Schmitt Trigger, he also made many other significant scientific contributions. Besides his scientific work Otto was involved in early organizational activities, which included the first large professional BME meeting in Minneapolis in 1958. A description of his many contributions will be presented along with a short video of Schmitt giving a tour of his laboratory, including the original Schmitt Trigger and the model he used to develop his vector ECG system. Otto Schmitt is probably best known for his Schmitt Trigger circuit which is widely used, at least in functional form, in many electronic devices today. His contributions are very diverse and include developing an important technique to detect submarines during World War II that is still used today, creating one of the best vector electrocardiographic systems, and his strong interest in paranormal investigations[1]. He introduced the word “biomimetics” to the world in a paper in 1969, which appeared in Webster’s Dictionary in 1974[1]. At the 1992 AAMI meeting, which awarded him the Laufman Prize, he presented a scholarly document with 12 action items for improving health care in this century [2]. This document included technical items such as home health care, but also surprisingly conscience and “prime features of quality of life, mind, spirit, and soul.” Besides his scientific work, he was involved in many organizational efforts. Before NASA there were four committees dealing with space and Otto was on three of the four and chaired the committee on Bioastronautics. In 1947, a joint committee of AIEE, IRE, and ISA organized annual conferences on electrical issues in medicine over the next 10 years. These conferences were only attended by a small group with a few dozen presentations per year. In 1958, Schmitt organized a theme based meeting on “biology and computers” at the University of Minnesota which had 70 papers and 400 attendees. He was the founding president of the Biomedical Engineering Society and the founding vice president of the Biophysical Society. Schmitt contributed greatly to the development of EMBS and was twice given the Morlock Memorial award, which is now renamed as IEEE-EMBS Career Achievement Award. In 1979 he was elected to the National Academy of Engineering and in 1987, he received the Centennial Medal from the IEEE.
Durk Gorter (ed.), Linguistic landscape: A new approach to multilingualism

Durk Gorter (ed.), Linguistic landscape: A new approach to multilingualism. Clevedon: Multilingual Matters, 2006. Pp. 1, 89. Hb $54.95.The four articles in this book adopt the definition of linguistic landscape (LL) offered by Rodrigue Landry & Richard Y. Bourhis (1997:25) as their authors investigate the visual makeup of cities worldwide: “The language of public road signs, advertising billboards, street names, place names, commercial shop signs, and public signs on government buildings combines to form the linguistic landscape of a given territory, region, or urban conglomeration.” The authors categorize signs as either top-down (official signs issued by public bureaucracies) or bottom-up (non-official signs posted by individuals or businesses), and each article examines details such as where the signs appear, the order and relative prominence of languages on multilingual signs, and whether or not multilingual signs contain (full or partial) translations.
Floating-Point Constants and Variables

This chapter explains the basic principles of using floating-point numbers. Some of the IDL commands and notations used include floating and double-precision notation such as 0.0, 1.0E3, 2.0D4, Inf, and NaN; FLOAT function; DOUBLE function; LONG function; FINDGEN function; !VALUES system variable; and TOTAL function and NAN keyword. The chapter covers the most important aspects of floating-point arithmetic for beginning programmers and illustrates some of the problems that can occur when making calculations with floating-point numbers. The most commonly used floating-point types include single precision and double precision. The other floating-point types available in IDL are described in the IDL documentation. The chapter also presents some general guidelines for floating-point calculations. Floating-point numbers should not be used when integers are more natural and one should try to avoid adding numbers that have different magnitudes. One should also try to avoid subtracting numbers that have similar magnitudes and double precision should be used as it can expand the range of calculations that one can do with good precision.
Uniformity of the fluid flow velocities within hollow fiber membranes of blood oxygenation devices.

: A finite volume-based computational model was developed to investigate the uniformity of the fluid flow across the hollow fiber membranes in blood oxygenation devices. A two-dimensional annular cross section of a blood oxygenation device including about 3300 hollow fiber membranes was used in the computation model. The equations governing the steady incompressible laminar flow in the blood oxygenation device were solved numerically and the results were compared with those obtained from the equivalent porous medium approximation. For the porous medium approximation, the Ergun equation was used for evaluating the permeability. The simulation results showed that the fluid molecules spend about six times longer in the fiber bundle region than that in its equivalent porous medium approximation model. The computational model also provides a more detailed fluid flow pattern in the membrane compartment of the blood oxygenator.
5. The Priority of Liberty: Rawls and “Tiers of Scrutiny”

In the United States, exceptionally, an established judicial protocol for constitutional clearance of legislative incursions on freedom of action sets up a two-track scheme, prescribing a searching form of review for a subset of such incursions and a markedly more cursory review for the rest. The model further sets up a general standard of 'fundamentality' by which to sort such incursions into the two classes – as opposed, say, to a name-by-name specification of protected liberties drawn directly from the text of the bill of rights. Political Liberalism, I argue, should be at home with both these features of the U.S. jurisprudence. The role assigned by that jurisprudence to fifth and fourteenth amendment 'liberty' is matched by the role assigned to 'liberty of conscience' in Rawlsian political philosophy; while the second principle of justice (and not, as might appear, any Rawlsian philosophical denial of value to freedom of action 'as such') points toward a refusal of heightened-scrutiny protection for freedom of action across the board. In a Rawlsian well-ordered society, two-track scrutiny would be understandable as a device for holding the two principles of justice in equipoise.This is a revised version of my paper previously posted as 'The Priority of Liberty: Rawls and a 'Warren Court Model,' SSRN Abstract ID 1927292 The revisions, which mostly occur in Parts I.A and I.B, have been largely prompted by the trenchant, skeptical treatment of the two-tier model in Chapter 9 of James Fleming’s and Linda McClain’s recently published book, 'Ordered Liberty.'This paper is under preparation for inclusion in a forthcoming collection: Thom Brooks & Martha Nussbaum (eds), Rawls’s Political Liberalism (New York: Columbia University Press, 2013).
A Conceptual Framework for Understanding Students' with Disabilities Transition to Community College

Students with disabilities are significantly underrepresented in the nation's community college population for multiple reasons. These include low expectations, poor high school preparation and transition planning, lack of communication or support services, and ineffective or poor support from school services personnel and faculty. This paper presents a literature synthesis. Its purpose is to inform an initial framework for building towards a conceptual framework for understanding the transition to community college by students with disabilities. The framework was developed from an earlier mixed methods study involving 100 college students with disabilities and 10 disability resource counselors in eight universities and colleges, six of which were community colleges. The framework was examined by comparing six reviews from the What Works in Transition: Systematic Review Project (meta-analyses of previous studies) and five meta-syntheses (rigorous evaluations). Based on these analyses, elements of the fram...
The Iowa Cyclonic-Anticyclonic Tornado Pair and Its Parent Thunderstorm

Abstract A severe thunderstorm which spawned at least four tornadoes, one of them anticyclonic, formed over central Iowa during the afternoon of 13 June 1976. This storm moved toward the east-northeast, approximately parallel to but slower than the mean tropospheric flow. The anticyclonic tornado (F3) and the most intense (F5) of the cyclonic tornadoes coexisted for 23 min and traveled on nearly parallel, cycloidal-like tracks, with the anticyclonic tornado 3–5 km southeast of the cyclonic. The major emphasis of this paper is on this pair of tornadoes and their relationship to the structure and evolution of the parent thunderstorm. Radar recorded the development of a hook echo just prior to the genesis of the intense cyclonic tornado. A strengthening mesolow was centered somewhere south of this tornado soon after it formed. The mesolow is believed to have initiated a new updraft; the anticyclonic tornado formed in association with this updraft, south of the cyclonic tornado. It is hypothesized that the me...
Plasmon drag effect in plasmonic metasurfaces

Plasmonics is promising for future electronics as it can combine optical speed of operation with nanoscale size, something which is not possible with traditional optics and electronics [1]. Coupling of photons, plasmonic excitations and electrons is of key importance as it provides opportunities to monitor or control plasmonic nanocircuits electrically.
Smooth interactive submodular set cover

Interactive submodular set cover is an interactive variant of submodular set cover over a hypothesis class of submodular functions, where the goal is to satisfy all sufficiently plausible submodular functions to a target threshold using as few (cost-weighted) actions as possible. It models settings where there is uncertainty regarding which submodular function to optimize. In this paper, we propose a new extension, which we call smooth interactive submodular set cover, that allows the target threshold to vary depending on the plausibility of each hypothesis. We present the first algorithm for this more general setting with theoretical guarantees on optimality. We further show how to extend our approach to deal with real-valued functions, which yields new theoretical results for real-valued submodular set cover for both the interactive and non-interactive settings.
Reduction in nevus biopsies in patients monitored by total body photography

Background Total body photography (TBP) can facilitate identification of new and changing lesions. By confirming that particular nevi are stable, TBP may reduce nevus biopsies. Objectives We sought to determine the number and rate of nevus biopsies before and after TBP, and the factors associated with increased biopsy rate during monitoring by TBP. Methods We reviewed records of all patients in 2 pigmented lesion clinics (PLCs) who received TBP and had 2 or more follow-up visits over a period of 2 years or longer. Results Before PLCs and TBP, the mean number of nevus biopsies per patient was 5.92 (589 patients) at a mean rate of 1.62 per year (160 patients). After TBP in PLCs, the same patients averaged 1.56 biopsies at a mean rate of 0.34 per year ( P −16 ). The entire cohort (926 patients) averaged similarly low post-TBP biopsy rates of less than 0.2 per year and per visit. Biopsy rates after TBP were positively correlated with decreased age, male gender, and family history of melanoma, but not nevus number. Limitations Some information was not available for some patients. Conclusions Patients at risk for melanoma experienced a 3.8-fold reduction in nevus biopsies after TBP. Younger male patients with family history of melanoma had higher biopsy rates after TBP.

Bandwidth-Based Control Strategy for a Series HEV With Light Energy Storage System

The twin goals of maximizing fuel economy (FE) and improving consumer acceptance by reducing the cost of the energy storage system (ESS) in a series hybrid electric vehicle (SHEV) powertrain is addressed here by using energy storage as a means for filtering drive-cycle power demands on the engine, rather than an energy source for supplying an all-electric drive mode. The concept is intended to minimize, if not eliminate, the battery in the SHEV without resorting to full-range proportional control of the engine and generator. An initial optimization study reported for a mid-size SHEV showed that a 4.5-kWh lithium-ion battery pack was still required. In this paper, a sports-car-class SHEV was studied, where the challenge is to reduce the size of the ESS even more because the available space allocation is only one fourth that of the mid-size vehicle. In this paper, a controller is developed, which allows a hybridized SHEV to be realized with a light ESS. The controller includes a duty-cycling feature that manages the engine performance in multiple efficient regions and a bandwidth-limited (BWL) proportional controller feature that limits low-bandwidth battery current. The performance of the controller has been validated for a SHEV powertrain model with an 80- $\text{V}_{\mathrm{dc}}$ 1.125-kWh battery, plus an 80- $\text{V}_{\mathrm{dc}}$ 46.4-F ultracapacitor module using a customized Autonomie vehicle model. The results show that the combined FE of the new design is increased by 13%, compared with the corresponding FE in the equivalent conventional vehicle. Additional FE improvement is possible by reducing the engine size further to reflect the average power demand imposed by real drive cycles.
Hepatic organelle interaction. II. Effect of tricarboxylic acid cycle intermediates on N-demethylation and hydroxylation reactions in rat liver.

Hepatocytes in rat liver slices accomplish the slow oxidative metabolism of drugs like aminopyrine and ethylmorphine. Although the enzyme system responsibile for this metabolism resides in the endoplasmic reticulum, mitochondrial Krebs cycle intermediates also affect the process. Succinate and isocitrate each elevate the metabolism of aminopyrine and ethylmorphine about 2-3-fold; none of the other intermediates tested had any effect. NADPH elevated the rates of aminopyrine and ethylmorphine N-demethylation 18- and 28-fold, respectively; NADP was only 50% as effective as NADPH in supporting these oxidations. When NADPH and isocitrate were added together, an additive effect was obtained on aminopyrine and ethylmorphine oxidation; the combination of succinate and NADPH caused a synergistic effect, more marked on the oxidation of aminopyrine than of ethylmorphine. Fumarate, oxalacetate, or malate, when combined with NADPH, was antagonistic to the liver slice oxidation of these two drugs, while malonate, when added with succinate and NADPH, only removed the synergism. The same effects as obtained with liver slices could be demonstrated with whole liver homogenates, but not with isolated liver microsomes. None of the Krebs cycle intermediates had a stimulatory effect on aniline hydroxylation, although oxalacetate decreased the hydroxylation seen with aminopyrine and ethylmorphine. These observations indicate that drug metabolism in the hepatocyte endoplasmic reticulum is controlled by the mitochondria, not merely via a flow of reducing equivalents, since even in the presence of an excess of NADPH succinate exerts a synergistic effect, more than doubling the rate of aminopyrine oxidation and causing a 50% increase in ethylmorphine oxidation.
Detecting recrystallization in a single crystal Ni-base alloy using resonant ultrasound spectroscopy

Abstract The use of resonant ultrasound spectroscopy (RUS) as a nondestructive evaluation (NDE) technique for Ni-base single crystal superalloys has been investigated. Manufacture of single crystal superalloys can be challenging due to the prevalence of defects induced during single crystal growth or subsequent processing. Common defects involve the presence of misoriented (non-single crystal) material that change the bulk elastic properties and, as a result, are detectable by RUS. To control the extent of misoriented material, recrystallization induced by shot peening the surface of the single crystal has been studied. RUS was then used to determine the presence and depth of misoriented material due to recrystallization. Recrystallization of shot peened cylindrical single crystal specimens occurred to a depth of 80 μm and 178 μm during subsequent heat treatments. Experimental average resonance frequency shifts of 1.835% ±1.704% and 2.380% ±2.910%, respectively, were measured over a frequency range from 20–200 kHz when compared to the baseline shot peened condition. Finite element (FE) models using the ABAQUS Lanczos Eigen frequency solver assessed the influence of recrystallization as a function of depth from the surface and showed good agreement with the measured resonance frequency shifts. For the greatest NDE sensitivity on production-scale turbine blades and other gas turbine components, a coupled RUS measurement and FE modeling approach is essential, and has the potential to improve single crystal processing approaches and manufacturing yields.
Mode Effect and Response Rate Issues in Mixed-Mode Survey Research: Implications for Recreational Fisheries Management

AbstractWhile the social, economic, and ecological impact of recreational fisheries is well established, the inherent diversity of both fisheries resources and resource users, particularly anglers, continues to present a challenge for management agencies. To better understand the diversity of recreational anglers, agencies often utilize survey methods to collect data on angler characteristics and preferences. However, obtaining necessary and representative data is becoming more challenging, exacerbated by declining response rates and an increase in the number of single and mixed-mode survey designs researchers can choose to collect data. We examined three survey designs—surface mail with a Web push, e-mail, and mixed mode—each with varying modes of solicitation and response, in the context of a statewide survey of licensed Texas anglers. Our findings illustrated that response rates varied considerably among these three survey designs. We also observed significant variation in terms of anglers’ sociodemogr...
Transformation of cable TV driven by the satellite TV broadcast revolution

The rapid evolution of satellite TV broadcast technology resulted in a tremendous increase in the number of available TV programs. Cable TV systems worldwide faced the challenge of expanding program capacity to catch up with the ever increasing number of programs being broadcast. In this paper, I will share the sequence of development, which transformed cable TV installations for Oil & Gas residential communities in Saudi Arabia and I will highlight the distinctive nature of such installations.
Comparison of Spectra Optia and COBE Spectra apheresis systems' performances for red blood cell exchange procedures

Abstract Background Spectra Optia (Terumo BCT, Lakewood, CO) was FDA approved for red blood cell exchange (RBCx) procedures in January 2014 and is expected to replace COBE spectra (Terumo BCT) very soon in the USA. The performance characteristics of these devices for Isovolemic Hemodilution (IHD-RBCx) procedure were compared in this study. Methods A total of 114 IHD-RBCx procedures from 19 patients were analyzed. For every patient, three procedures on each device with similar pre-procedure hematocrits were compared. Pre and post procedure laboratory parameters compared were hemoglobin S (HbS), hematocrits (Hct), platelet counts and fraction of cells remaining (FCR). Statistical analysis was performed using t-test adjusted by the Holm-Bonferroni method to reduce family-wise error rate. Results There were no significant differences between these two devices in regards to HbS, Hct, FCR and platelet counts (p = > 0.05). However, rinseback volume (124.2 ± 8.9 ml) and normal saline replacement volume during IHD phase (296.1 ± 97.2 ml) were lower in Spectra Optia as compared to COBE Spectra (337 ± 33.8 ml and 326.6 ± 105.2 ml, p value Conclusions Performance characteristics of Spectra Optia for HbS, Hct and FCR were similar to COBE Spectra for IHD-RBCx. IHD-RBCx procedure on Optia required less normal saline replacement volume and rinse back volume but with overall longer procedure run time.
Toward a Unique Definition of the Mutation Rate

In around 1943, while writing a classic paper with Luria, Delbruck envisioned two kinds of mutation rates: One was expressed as mutations per bacterium per unit time, the other as mutations per bacterium per division cycle. Due to minor mathematical errors, the precise connection between the two concepts remained elusive for Delbruck. As a result, researchers and educators alike are still grappling with the definition of the mutation rate. Within the context of microbial mutation, the current author proposes an idealized model to bring new clarity to the distinction between the two forms of the mutation rate that Delbruck once attempted to define and characterize. The paper also critiques two incorrect estimators of mutation rates and brings to light two important yet unexplored “invariance” hypotheses about mutation rates.
Systolic and pulse pressure associate with incident knee osteoarthritis: data from the Osteoarthritis Initiative.

We evaluated the relationship of systolic blood pressure, diastolic blood pressure, pulse pressure, and treatment with antihypertensives with knee osteoarthritis incidence in a US cohort. We performed a longitudinal study (2004–2010) nested within the Osteoarthritis Initiative Study including only individuals without knee osteoarthritis at baseline. Systolic blood pressure, diastolic blood pressure, and pulse pressure were assessed at baseline, 12-, 24-, and 36-month visits. Knee radiographs at baseline, 12-, 24-, 36- and 48-month visits defined radiographic osteoarthritis, Kellgren and Lawrence grade ≥2. We performed logistic regression, adjusting for age, sex, body mass index, NSAID use, number of antihypertensive medications, diabetic medications, and cholesterol medications. One thousand nine hundred and thirty people (6040 observations) were included. Annual incidence rates of radiographic osteoarthritis by systolic blood pressure quartiles (lowest to highest) were 2.1, 3.4, 3.7, and 3.7%. Fully adjusted odds ratios of incident radiographic osteoarthritis (OA) for the 2nd-4th quartiles were 1.6, 1.7, and 1.6 relative to the lowest quartile (p for trend = 0.03). Pulse pressure results were similar. There was no association with diastolic blood pressure. Compared to those not taking any antihypertensive medications, those taking ≥3 had decreased odds (0.4, 0.1–1.0) of developing incident OA. In a US cohort, higher systolic blood pressure and pulse pressure are associated with increased incidence of radiographic knee osteoarthritis while treatment with ≥3 antihypertensive medications was associated with reduced incidence. These findings suggest a new and promising avenue for research on disease modification in knee osteoarthritis.
Abstract P190: Role of mTOR Signaling in LEOPARD-Syndrome-Associated Hypertrophic Cardiomyopathy

The identification of mutations in PTPN11 (encoding the protein tyrosine phosphatase Shp2) in families with congenital heart disease has facilitated mechanistic studies of various cardiovascular defects. However, the roles of normal and mutant Shp2 in the developing heart are still poorly understood. In particular, how Shp2 loss-of-function (LOF) mutations cause LEOPARD Syndrome, which is characterized by congenital heart defects such as pulmonary valve stenosis and hypertrophic cardiomyopathy (HCM), remains unclear. We employed both in vitro and in vivo models to investigate signaling mechanisms downstream of Q510E-Shp2, a particularly aggressive mutation leading to early-onset HCM. In cultured rat neonatal cardiomyocytes, Q510E-Shp2 expression significantly increased cell size. This increase was accompanied by hyperactivation of signaling through mammalian target of rapamycin (mTOR). mTOR inhibition with rapamycin reversed the pro-hypertrophic effects of Q510E-Shp2 in culture. Mice with cardiomyocyte-specific overexpression of Q510E-Shp2 starting before birth also showed up-regulation of signaling through Akt/mTOR/p70S6K and developed HCM in the early neonatal period. Q510E-Shp2 expression increased cardiomyocyte sizes and septum thickness, and caused cardiomyocyte disarray and fibrosis. Echocardiographically, hearts were hypocontractile and displayed increased wall thicknesses. Importantly, rapamycin administration rescued the Q510E-Shp2-induced phenotype in vivo. Our studies establish a role for mTOR signaling in HCM caused by the LOF mutation Q510E-Shp2. Pharmacological inhibition of mTOR was sufficient to rescue the HCM phenotype in both models. These findings have important implications not only for the development of novel therapeutic approaches for LEOPARD Syndrome patients, but also for closely related forms of congenital heart disease such as Noonan Syndrome.
Optimal transmission for energy harvesting nodes under battery size and usage constraints

In this paper, we study the optimal energy management policy of an energy harvesting transmitter by taking both battery degradation and finite battery constraints into consideration. We consider a scenario where the sensor is able to harvest energy from the ambient environment and use it to power its transmission. The harvested energy can be used for transmission immediately without entering the equipped battery, or charged into the battery and discharged later for transmission. When the battery is charged or discharged, a cost will be incurred to account for its impact on battery degradation. We impose a long-term average cost constraint on the battery, which is translated to the average number of charge/discharge operations per unit time. At the same time, we assume the capacity of the battery is finite, and the total amount of energy stored in the battery cannot exceed its capacity. Our objective is to develop an online energy management policy to maximize the long-term average throughput of the transmitter under both the battery usage constraint and finite battery constraint. We propose an energy-aware adaptive transmission policy, which is a modified version of the optimal policy for the infinite battery case. Our analysis indicates that the energy-aware adaptive transmission policy is asymptotically optimal when the battery size is sufficiently large. Simulation results corroborate the theoretical analysis.

Neuromuscular Disorders in Pregnancy

Neuromuscular disorders may present and progress differently in women than in men. During pregnancy, medication adjustment, hormonal effects, and other alterations in physiology may influence the manifestation of a variety of neuromuscular disorders. The expression of existing conditions may change; previously asymptomatic conditions may be unmasked, or entirely new conditions may develop. Additionally, neuromuscular disorders and their treatments may have implications for the fetus. Such factors must be carefully considered when counseling and treating pregnant women and those considering pregnancy. This article reviews considerations specific to women and issues surrounding pregnancy in disorders of the neuromuscular junction, focal neuropathies, and acquired and inherited disorders of the nerve and muscle.

Love and Will in the Awakening

Love and will are two of the elemental passions of the soul that overlap and entangle one another. They are also the theme of Kate Chopin’s The Awakening and form the title of a book by Rollo May. I will focus on May’s and Chopin’s descriptions of how lack of will results in an inability to love, and I will argue that May’s account of love and will illuminates the actions of Edna, the main character in The Awakening. But I must also confess a digression into Pfander’s account of willing since I believe it is a valuable addition to May.

Stable, Temperature-Dependent Gas Mixture Permeation and Separation through Suspended Nanoporous Single-Layer Graphene Membranes.

Graphene membranes with nanometer-scale pores could exhibit an extremely high permeance and selectivity for the separation of gas mixtures. However, to date, no experimental measurements of gas mixture separation through nanoporous single-layer graphene (SLG) membranes have been reported. Herein, we report the first measurements of the temperature-dependent permeance of gas mixtures in an equimolar mixture feed containing H2, He, CH4, CO2, and SF6 from 22 to 208 °C through SLG membranes containing nanopores formed spontaneously during graphene synthesis. Five membranes were fabricated by transfer of CVD graphene from catalytic Cu film onto channels framed in impermeable Ni. Two membranes exhibited gas permeances on the order of 10–6 to 10–5 mol m–2 s–1 Pa–1 as well as gas mixture selectivities higher than the Knudsen effusion selectivities predicted by the gas effusion mechanism. We show that a new steric selectivity mechanism explains the permeance data and selectivities. This mechanism predicts a mean p...
Using Public Private Partnerships to Accelerate Student Success

Metropolitan State University of Denver (MSU Denver) has used various ways to craft curriculum that directly meets employers’ and students’ needs in key economic drivers in the State of Colorado. Moving beyond the standard industry advisory councils used in many, especially professional programs, the institution has consulted with industry leaders prior to building facilities and developing curriculum to ensure industry needs are met. As MSU Denver faculty collaborated with their industry partners, they worked to embed both content and skills throughout the curriculum to ensure alumni were prepared for this 21st Century workplace. Additionally, MSU Denver has honored past experience and on the job training of employers and employees in a way that many four-year institutions have resisted.
The Possibility of Becoming in Pedro Almodóvar’s Mujeres al borde de un ataque de nervios (1988) and Los abrazos rotos (2009)

espanolEl tratamiento visual persistente, multiforme y aparentemente trivial de la fruta por parte de Pedro Almodovar en Mujeres al borde de un ataque de nervios (1988) y en Los abrazos rotos (2009), se basa, segun planteo, en la ontologia fenomenologica de Jean-Paul Sartre. En 1977 Almodovar actuo en la produccion espanola de la obra de Sartre, Las manos sucias (1948), en la que conoceria a Carmen Maura y la filosofia del existencialista frances. El contacto temprano con las ideas de Sartre, cuya fenomenologia niega la existencia de un ego fijo y un ser esencial, ejerceria una influencia profunda en las conceptualizaciones posmodernas de la subjetividad y jugo un papel formativo en la preocupacion filmica del director con la politica del cuerpo. Asimismo, ambas protagonistas femeninas logran superar la homogeneidad y la falta de diferenciacion sartreanas; es precisamente esta lucha el fundamento para liberarse de una existencia ‘fija’ impuesta por los hombres que las objet-ivisan EnglishThe persistent, multiform, and seemingly inconsequential visual treatment of fruit by Pedro Almodovar in the two closely tied films, Mujeres al borde de un ataque de nervios (1988) and Los abrazos rotos (2009), I argue here, draws on the phenomenological ontology of Jean-Paul Sartre. Almodovar participated in a 1977 Spanish production of Sartre’s Dirty Hands (1948), where he would meet Carmen Maura and become familiar with the philosophy of the French existentialist. This early exposure to Sartre, whose phenomenology denies the existence of a fixed ego and an essential self, would exert profound influences on postmodern conceptions of subjectivity and was formative, I sustain, in the director’s filmic preoccupation with body politics. Moreover, I argue that the female protagonists of both films overcome Sartrean homogeneity and lack of differentiation; it is precisely this struggle that constitutes the ground for their freedom from a ‘fixed’ existence by the men who object-ify them.
Why States Should Tax the GILTI

A centerpiece of the 2017 federal tax legislation’s reforms to international corporate income tax rules is the new global intangible low-taxed income regime (or GILTI). This essay addresses the question of whether U.S. state governments should conform to this new federal GILTI regime. As a matter of tax policy, this essay argues that the answer is clearly yes.
Innovative pH sensors developed from ultrafine fibers containing açaí (Euterpe oleracea) extract.

Abstract This work describes the development of ultrafine fibers with acai (Euterpe oleracea Mart.) extract (AE) for use as pH sensors with potential applications in the food industry. The fibers were produced by electrospinning with polymeric solutions composed of 7% (w v−1) polycaprolactone, 2% (w v−1) polyethylene oxide and 3% (w v−1) AE solubilized in chloroform and methanol (3:1). The mean diameter of the fibers was 1635 ± 277 nm, with hydrophilic characteristics (contact angle
Fast high-fidelity entangling gates for spin qubits in Si double quantum dots

Implementing high-fidelity two-qubit gates in single-electron spin qubits in silicon double quantum dots is still a major challenge. In this work we employ analytical methods to design control pulses that generate high-fidelity entangling gates for quantum computers based on this platform. Using realistic parameters and initially assuming a noise-free environment, we present simple control pulses that generate cnot, cphase, and cz gates with average fidelities greater than 99.99% and gate times as short as 45 ns. Moreover, using the local invariants of the system's evolution operator, we show that a simple square pulse generates a cnot gate in less than 27 ns and with a fidelity greater than 99.99%. Last, we use the same analytical methods to generate two-qubit gates locally equivalent to $\sqrt{\mathrm{CNOT}}$ and $\sqrt{\mathrm{CZ}}$ that are used to implement simple two-piece pulse sequences that produce high-fidelity cnot and cz gates in the presence of low-frequency noise.

A VNTR Regulates miR-137 Expression Through Novel Alternative Splicing and Contributes to Risk for Schizophrenia.

The MIR137HG gene encoding microRNA-137 (miR-137) is genome-wide associated with schizophrenia (SZ), however, the underlying molecular mechanisms remain unknown. Through cloning and sequencing of individual transcripts from fetal and adult human brain tissues we describe novel pri-miR-137 splice variants which exclude the mature miR-137 sequence termed ‘del-miR-137’ that would function to down-regulate miR-137 expression. Sequencing results demonstrate a significant positive association between del-miR-137 transcripts and the length of a proximal variable number tandem repeat (VNTR) element. Additionally, a significantly higher proportion of sequenced transcripts from fetal brain were del-miR-137 transcripts indicating neurodevelopmental splicing regulation. In-silico results predict an independent regulatory function for del-miR-137 transcripts through competitive endogenous RNA function. A case-control haplotype analysis (n = 998) in SZ implicates short VNTR length in risk, with longer lengths imparting a protective effect. Rare high risk haplotypes were also observed indicating multiple risk variants within the region. A second haplotype analysis was performed to evaluate recombination effects excluding the VNTR and results indicate that recombination of the region was found to independently contribute to risk. Evaluation of the evolutionary conservation of the VNTR reveals a human lineage specific expansion. These findings shed further light on the risk architecture of the miR-137 region and provide a novel regulatory mechanism through VNTR length and alternative MIR137HG transcripts which contribute to risk for SZ.
The supply blockchain: integrating blockchain technology within supply chain operations

Abstract Blockchain is a distributed system of record that employs a trust protocol built on elements of networking and cryptology. Blockchain can improve the speed of transaction execution and validation across multiple parties. These include digitally validating a transaction that has occurred between two entities and rendering it irrefutable. When one considers the numerous kinds and volume of supply chain transactions that occur daily, this fundamental capability can have profound impacts. Having readily available information that is trustworthy can streamline activities such as purchasing, contracting, and qualifying materials. This chapter surveys some current applications of blockchain by early industry adopters, upon which it explores additional potential applications for supply chain operations. It concludes with a prescriptive approach for how enterprises can determine and identify effective implementation scenarios for blockchain in their supply chain operations.
Blow-up for the 1D nonlinear Schrödinger equation with point nonlinearity I: Basic theory

Abstract We consider the 1D nonlinear Schrodinger equation (NLS) with focusing point nonlinearity, (0.1) i ∂ t ψ + ∂ x 2 ψ + δ | ψ | p − 1 ψ = 0 , where δ = δ ( x ) is the delta function supported at the origin. In this work, we show that (0.1) shares many properties in common with those previously established for the focusing autonomous translationally-invariant NLS (0.2) i ∂ t ψ + Δ ψ + | ψ | p − 1 ψ = 0 . The critical Sobolev space H ˙ σ c for (0.1) is σ c = 1 2 − 1 p − 1 , whereas for (0.2) it is σ c = d 2 − 2 p − 1 . In particular, the L 2 critical case for (0.1) is p = 3 . We prove several results pertaining to blow-up for (0.1) that correspond to key classical results for (0.2). Specifically, we (1) obtain a sharp Gagliardo-Nirenberg inequality analogous to Weinstein [44] , (2) apply the sharp Gagliardo-Nirenberg inequality and a local virial identity to obtain a sharp global existence/blow-up threshold analogous to Weinstein [44] , Glassey [17] in the case σ c = 0 and Duyckaerts, Holmer, & Roudenko [12] , Guevara [18] , and Fang, Xie, & Cazenave, [13] for 0 σ c 1 , (3) prove a sharp mass concentration result in the L 2 critical case analogous to Tsutsumi [43] , Merle & Tsutsumi [36] and (4) show that minimal mass blow-up solutions in the L 2 critical case are pseudoconformal transformations of the ground state, analogous to Merle [28] .

Phase reversion kinetics of thermally decomposed (α + γ′) phases to γ-phase in U – 10 wt% Mo alloy

Abstract Thermally induced phase reversion kinetics of decomposed α + γ′ phases to γ phase was investigated for the U – 10 wt% Mo (U–10Mo) hypoeutectoid alloy using X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The as-cast U–10Mo alloy was homogenized to the γ phase at 1073 K for 96 h, and decomposed at sub-eutectoid temperature of 773 K as a function of time from 240 to 1200 h. The decomposition of γ phase initiated via two mechanisms: (1) discontinuous precipitation (DP) or cellular precipitation along the grain boundaries and inclusions; and (2) continuous precipitation (CP) within the γ grains as γ′ needles. After 720 h at 773 K, the DP colonies completely consumed the continuous γ matrix, after which discontinuous coarsening (DC) was observed. The completely-decomposed U–10Mo alloy samples were then annealed at 843, 853, and 863 K as a function of time to document the kinetics of α+γ’ → γ phase reversion. The reference intensity ratio analysis was employed to XRD patterns to quantify the phase amount after each heat treatment. A combinatorial kinetic model, consisting of the classical JMAK nucleation and growth, and spherical particle dissolution, was employed to describe the α+γ’ → γ phase reversion as a function of time and temperature. This phenomenological model provided a good approximation for the phase reversion within the temperature and time ranges examined in this study. Furthermore, a diffusion enhancement approach was employed for a set of typical irradiation parameters to estimate the irradiation effect on the α+γ’ → γ phase reversion kinetics.

Forensic Evidence in Arizona: Reforms for Victims and Defendants

This Article identifies the strengths of the current system in Arizona and proposes innovative reforms appropriate for labs that are already leaders in the field. Arizona is particularly well situated to increase its lab independence and to serve additional members of the criminal legal community: namely, defendants and victims. Regarding defendants, this Article recommends greater transparency and accessibility to fundamental scientific lab findings for defense attorneys, similar to the practices of well-known independent crime labs such as the Houston Forensic Science Center. Additionally, the volunteer-run Arizona Forensic Science Advisory Committee can ensure greater integrity for forensic evidence in the courtroom if it is staffed, ideally with a staff attorney. Regarding victims, in a moment of calls to “defund the police,” this Article proposes that police departments shift resources to hire more civilian crime scene investigators. More civilian investigators can increase responsiveness to property crimes for victims and also identify the scope of the property crime problem in regularly impacted neighborhoods. Economically struggling neighborhoods are frequently overpoliced for controlled substances violations, yet law enforcement is simultaneously under-responsive to victims of property crime in these communities.
How to test SARS-CoV-2 vaccines ethically even after one is available.

Although vaccines against SARS-CoV-2 have now been found safe and efficacious, there remains an urgent global health need to test both these vaccines and additional vaccines against the same virus. Under variable conditions, either standard or unusual designs would for both familiar and often-missed reasons make continued testing possible and ethical.
CrimeScape: Analysis of socio-spatial associations of urban residential motor vehicle theft.

Abstract This paper focuses on advancing the traditional association rule mining (ARM) approach to capture the rich, multidimensional and multiscalar context that is anticipated to be associated with residential Motor Vehicle Theft (MVT) across urban environments. We tackle the challenge to materialize complex social and spatial components in the mining process and present a novel interactive visualization based on social network analysis of rules and associations to facilitate the analysis of mined rules. The spatial ARM (SARM) findings successfully identify many socio-spatial associations to MVT prevalence and establish their relative influence on crime outcome in a case study. Also, the analysis provides unique insights to understand the interactive relationships between neighborhood characteristics and environmental features to both high and low MVT and underscores the importance of spatial properties of spillover and neighborhood effects on urban residential MVT prevalence. This work follows the tradition of inductive and abductive learning and presents a promising analysis framework using data mining which can be applied to different applications in social sciences.
Introduction to erectile dysfunction

Abstract Erectile dysfunction (ED), the inability to obtain or maintain an erection, is a common condition that can have significant psychosocial consequences for patients. Since ED affects both patients and their sexual partners, difficulty with achieving or maintaining an erection can contribute to the development of depression and anxiety that causes ED to worsen. Despite the adverse impacts on quality of life for patients, patients suffering from ED often delay or avoid seeking treatment. ED is important for providers to address for several reasons. In addition to the negative psychosocial consequences of ED, ED can be one of the initial manifestations of vascular disease that increases the risk of myocardial infarction or cerebrovascular accident. Therefore addressing ED can not only improve a patient’s quality of life but also provide an opportunity to address underlying etiologies of ED.
