An Analysis for a Novel Path Planning Method

The aim of disseminating this research article is to introduce a novel path planner method in detail and argue that it performs as well as other offline path planners in terms of analyzing and constructing collision-free trajectories in addition to shortest possible path from start to goal configurations. Our novel path planner is able to build optimal trajectories in terms of the shortest length as well as near miss avoidance route from the initial to the goal configuration. It allows a moving point robot to make a proper transition from its assigned goal toward a collision-free path in the reasonable time frame, successfully. As an offline path planner, our planner performs the operation of analyzing the environment on static workspaces with the fixed and known initial and the goal configurations and computing optimal trajectories, using global information about the environment. As a feature of novelty, our planner benefits of using a limited amount of global knowledge, however. This helps moving robot to allocate less system resources such as memory which leads the robot to perform the process of building optimal trajectories more efficiently. The shortest route is considered to be secure enough to enable mobile robot to maneuver among obstacles in workspace without involving any near misses. Our novel path planner is able to process any types of obstacles in terms of shapes and edges flawlessly. For instance, it can be applied on any spiral or curved obstacles successfully. This novelty feature distinguishes our offline path planner from the majority of other planners that are solely able to compute the optimal trajectories for certain obstacle shapes such as polygonal obstacles. Moreover, this paper attempts to evaluate our novel path planner algorithm abilities and skills by examining it on selected workspaces. We also assess our novel path planner through comparing it with other planners to reveal its efficiency in terms of ability to route optimal trajectories in regards to minimizing trajectory distances from initial to the goal configurations as well as the reliability and safety of the optimal processed path.
Flushing in (neuro)endocrinology

Cutaneous flushing is a common presenting complaint in endocrine disorders. The pathophysiology of flushing involves changes in cutaneous blood flow triggered by multiple intrinsic factors that are either related to physiology or disease. Flushing can be divided into episodic or persistent causes. Episodic flushing is mediated by the release of endogenous vasoactive mediators or medications, while persistent flushing results in a fixed facial erythema with telangiectasia and cyanosis due to slow-flowing deoxygenated blood in large cutaneous blood vessels. The differential diagnosis of cutaneous flushing in neuroendocrine disorders is limited, yet encompasses a broad spectrum of benign and malignant entities, including carcinoid syndrome, pheochromocytoma, Cushing syndrome, medullary thyroid cancer, and pancreatic neuroendocrine tumors. In this review, we provide a concise and up-to-date discussion on the differential diagnosis and approach of flushing in neuroendocrinology.
A Large-Scale Study in Predictability of Daily Activities and Places

Modeling human activity has a wide range of applications, including customized service for mobile users and resource management for mobile communications. Predicting future activities and places is a challenging task, as the activity pattern shows both regularity and randomness simultaneously. Time information such as time-of-day or day-of-week can partially explain this regularity. Furthermore, current activity and place may depend strongly on the activity and place history far back into the past. To capture this long-range temporal dependency, we used Long Short-Term Memory (LSTM) network, a state-of-the-art sequential model. Instead of predicting a future state of the immediate next step, we proposed multi-step look-ahead predictions to evaluate how far we could accurately predict future states up to 6 hours. Experiments on large-scale American Time Use Survey dataset showed that our model outperforms previous approaches, including Markov-based models, consistently achieving 0.3-7% relative improvement. We divided subjects into four groups by employment status, and we showed qualitatively that daily activity patterns are different among groups, and quantitatively that group-specific training is essential to accurately predict the future activity of individuals.
Digital Compensation of SSBI in Direct Detection Multicarrier System With SOA Nonlinearities

We demonstrate an efficient signal-signal beat interference (SSBI) compensation technique for a direct-detection multicarrier optical system for the first time in the presence of nonlinear transfer function introduced by a semiconductor optical amplifier (SOA). While conventional digital SSBI compensation takes into account the nonlinear effect of photo-detection due to the square-law characteristic, nonlinear wave mixing among subcarriers can also be introduced by gain saturation if the system transfer function is nonlinear, which reduces the effectiveness of digital SSBI compensation. Using the nonlinear transfer function of SOA as an example, we show that the effectiveness of SSBI compensation can be largely restored when the nonlinearity is properly modeled through digital backpropagation.
Statistical Thermodynamics of Point Defects in Crystals

Point defects play an important part in determining the physical properties of most crystalline substances, most notably those controlling the transport of matter and the properties that stem from it. They also strongly influence the resistivity of metals by scattering conduction electrons, the low-temperature thermal conductivity of all crystalline solids by scattering phonons, the electronic conduction and related properties of semiconductors by acting as donors or acceptors, and the optical properties of ionic solids by introducing electron states with optical transitions, to name a few examples. They are the primary principal product in irradiation of crystals by energetic particles, and their subsequent behavior very much determines the nature of the damage suffered by the crystal during irradiation and the recovery processes that occur during subsequent annealing.
Atherosclerosis as a Risk Factor for Venous Thromboembolism (VTE): A Population-Based Cohort Study.

While atherosclerosis has been suggested as a risk factor for VTE, previously identified mechanisms for atherosclerosis and VTE differ dramatically. Objectives: To compare (a) VTE-free survival and (b) observed vs. expected number of VTE events, among adult patients with and without aortic atherosclerosis. Design/Setting: Population-based prospective cohort study in Olmsted County, MN. Patients: Age- and sex-stratified random sample of the adult (≥45 years old) Olmsted County population identified over the three-year period, 1993–1995 (n=573), performed as part of the Stroke Prevention: Assessment of Risk in the Community ( SPARC ) study. Measurements: The SPARC study included a baseline clinical evaluation (interviews, review of medical records), blood pressure measurements, blood sampling, and transesophageal echocardiography ( TEE ). The Risk Factors for VTE in the Community study identified all incident VTE among Olmsted County residents over the 32-year period, 1966–1997, from which expected VTE events by age and sex were calculated. Results: Over 2830 person-years of follow-up, 12 SPARC patients developed VTE (7 idiopathic). The 4-year VTE-free survival was 99% and 98% for those with and those without any TEE-detected aortic atherosclerosis. Adjusting for age in a Cox proportional hazards model, lack of aortic atherosclerosis was significantly associated with subsequent VTE (p=0.01). Among the 276 patients without atherosclerosis observed for 1423 person-years, 7 VTE were observed compared to 2.6 expected (RR=2.7, 95%CI: 1.1, 5.6). Among the 291 patients with atherosclerosis (plaque ≥2mm), 4 VTE were observed compared to 5.8 expected (RR=0.7, 95%CI: 0.2, 1.8). Conclusions: Atherosclerosis is not a risk factor for incident VTE.
Scaling properties of topological invariants

The formalism of scaling relations between the reduced topological invariants is reviewed. First, the basic concepts of the chemical graph theory, the known approximate formulae for the total π-electron energy and the size extensivity of topological invariants are outlined. The scaling properties of the reduced topological invariants are introduced and the accuracy of various scaling functions is assessed. Finally, the stability index of benzenoid hydrocarbons and the lower and upper bounds to the reduced invariants are discussed.
Catalytic-site design for inverse heavy-enzyme isotope effects in human purine nucleoside phosphorylase

Heavy-enzyme isotope effects ( 15 N-, 13 C-, and 2 H-labeled protein) explore mass-dependent vibrational modes linked to catalysis. Transition path-sampling (TPS) calculations have predicted femtosecond dynamic coupling at the catalytic site of human purine nucleoside phosphorylase (PNP). Coupling is observed in heavy PNPs, where slowed barrier crossing caused a normal heavy-enzyme isotope effect ( k chem light / k chem heavy > 1.0). We used TPS to design mutant F159Y PNP, predicted to improve barrier crossing for heavy F159Y PNP, an attempt to generate a rare inverse heavy-enzyme isotope effect ( k chem light / k chem heavy
Cripping safe sex : Life Goes On's queer/disabled alliances.

Life Goes On (1989–1993) was the first television series in U.S. history not only to introduce a recurring teenaged HIV-positive character but also to feature an actor with Down syndrome in a leading role. Drawing new connections among disability studies, queer theory, and bioethics, I argue that Life responded to American disability rights activism and the AIDS epidemic of the early 1990s by depicting sex education as disability activism. By portraying fulfilling sexual relationships for its disabled protagonists, Life challenged heteronormative and ableist underpinnings of marriage, sexuality, reproduction, and sex education and imagined transgressive queer/disabled alliances that often surpassed those of activists of its cultural moment. By representing homophobia, AIDS-phobia, and ableism as intertwined oppressions, the series conjured an expansive vision of sexual justice and pleasure, one that included and united teenagers, intellectually disabled people, and seropositive people—populations whose sexualities have generally been regarded as pathological or nonexistent.
Evidence for altered insulin receptor signaling in Alzheimer's disease

Epidemiological data have shown that metabolic disease can increase the propensity for developing cognitive decline and dementia, particularly Alzheimer's disease (AD). While this interaction is not completely understood, clinical studies suggest that both hyper- and hypoinsulinemia are associated with an increased risk for developing AD. Indeed, insulin signaling is altered in post-mortem brain tissue from AD patients and treatments known to enhance insulin signaling can improve cognitive function. Further, clinical evidence has shown that AD patients and mouse models of AD often display alterations in peripheral metabolism. Since insulin is primarily derived from the periphery, it is likely that changes in peripheral insulin levels lead to alterations in central nervous system (CNS) insulin signaling and could contribute to cognitive decline and pathogenesis. Developing a better understanding of the relationship between alterations in peripheral metabolism and cognitive function might provide a foundation for the development of better treatment options for patients with AD. In this article we will begin to piece together the present data defining this relationship by briefly discussing insulin signaling in the periphery and CNS, its role in cognitive function, insulin's relationship to AD, peripheral metabolic alterations in mouse models of AD and how information from these models helps understand the mechanisms through which these changes potentially lead to impairments in insulin signaling in the CNS, and potential ways to target insulin signaling that could improve cognitive function in AD. This article is part of the Special Issue entitled 'Metabolic Impairment as Risk Factors for Neurodegenerative Disorders.'
Increase in suicides the months after the death of Robin Williams in the US.

Investigating suicides following the death of Robin Williams, a beloved actor and comedian, on August 11th, 2014, we used time-series analysis to estimate the expected number of suicides during the months following Williams’ death. Monthly suicide count data in the US (1999–2015) were from the Centers for Disease Control and Prevention Wide-ranging ONline Data for Epidemiologic Research (CDC WONDER). Expected suicides were calculated using a seasonal autoregressive integrated moving averages model to account for both the seasonal patterns and autoregression. Time-series models indicated that we would expect 16,849 suicides from August to December 2014; however, we observed 18,690 suicides in that period, suggesting an excess of 1,841 cases (9.85% increase). Although excess suicides were observed across gender and age groups, males and persons aged 30–44 had the greatest increase in excess suicide events. This study documents associations between Robin Williams’ death and suicide deaths in the population thereafter.
PRIOR HEART FAILURE (HF) HOSPITALIZATION AND 30-DAY AND 1-YEAR OUTCOMES IN PATIENTS WITH HF AND PRESERVED EJECTION FRACTION (HFPEF)

Hospitalized heart failure (HF) patients with a prior hospitalization are at a higher risk of post-discharge adverse outcomes. Less is known about this association in HFpEF. We examined the association of pre-admission HF hospitalization (HFH) with post-discharge outcomes. Of the 8873 hospitalized

This strain shows resistance to mercury and multiple antibiotics, and its genome sequence contains several gene sets known to confer resistance to heavy metals enzymatically and through multidrug efflux pumps.
Kanker in de familie: wanneer is verder onderzoek geïndiceerd?

Het identificeren van families met een erfelijke predispositie voor kanker is van belang in verband met de mogelijkheid van secundaire preventie . Door regelmatig onderzoek van (gezonde) familieleden kan men tumoren in een vroeg of premaligne stadium ontdekken, wat gunstig is voor de prognose. Naast de mogelijkheid van preventie is herkenning ook van belang omdat de behandeling van erfelijke kanker kan afwijken van die van niet-erfelijke kanker. De huisarts speelt, vanwege de poortwachtersfunctie, een zeer belangrijke rol in het selecteren van patienten die in aanmerking komen voor evaluatie in een klinisch genetisch centrum.
Computer Portrayals of the Sine-Gordon Breather as a Model of the de Broglie Double Solution

Computer portrayals are presented of a one-dimensional model of fundamental particles as developed by U. Enz from the breather solution of the nonlinear sine-Gordon equation in the context of soliton physics. Particles portrayed are the stationary and the moving basic nucleon and the stationary electron. The portrayals illustrate the nonlinear characteristics of the u wave anticipated by de Broglie as part of his proposed “double solution” in wave mechanics. Linear plots of u vs x for a moving breather exhibit the familiar single hump profile which moves with group velocity v g = sc. Plots of the signed logarithm of u vs x reveal both an apex corresponding to the single hump of the linear plot plus the de Broglie | waves which are strongly modulated by the exponential decrease (~ 43 decades per de Broglie wavelength) and which move with phase velocity v p = c/s. The semilogarithmic plot makes possible a unique portrayal of the wave packet representing a moving particle which shows the coexistence of both particle and wave.
NONPOINT SOURCE POLLUTION FROM PCBs: BIOAVAILABILITY AND INACTIVATION WITH ACTIVATED CARBON

ABSTRACT Polychlorinated biphenyls (PCBs) are widely distributed in small amounts in the soils of the U.S. and in moderate to high amounts in the sediments of many rivers and other bodies of water. Many species of plants and other organisms, including fish, which live in PCB contaminated environments absorb and translocate PCBs into their tissues. Activated carbon added to PCB contaminated soils reduced the biological availability of PCB by 90 to 100%.
SYSBLD2: A Computer-based Designing System for Multi-family Housing

ABSTRACT This paper reports on the development of a computer program which generates designs for multi-family housing from a database of apartment plans and their components. These plans are associated with a precast concrete modular housing system, although the program has been designed to be generic. The program development is part of an overall re-evaluation and update of an industrialized housing system to include passive energy technology. Design criteria are linked to the driving program by objective functions which, in turn, are linked to the energy and economic database through file procedures. The programn is written in PASCAL. Data input is interactive using a keyboard or digitizer; output is graphic.
Involuntary Hospitalization in the USSR

Cases of the Soviet State’s use of psychiatry in its struggle against political dissidents have received great publicity (1–16) and have provoked great indignation in the West (17–33). This indignation is largely incomprehensible to common Soviet people who know of more terrible instances of repression in the past (34).
Photo Quiz: A 66-Year-Old Man with Bloodstream Infection and Back Pain.

A 66-year-old man visiting from India with a history of type II diabetes mellitus was brought to the emergency department (ED) of the Auburn Medical Center (Auburn, WA) for fatigue, fever (101.5°F), and right flank and lower back pain. His examination revealed tachycardia (119 beats per minute) and
Nurses' drowsy driving prevention strategies: A qualitative exploratory multiple-case study

Objective: To explore the strategies registered and licensed practical nurses implemented to lessen the possibility of driving while drowsy after working nights in hospitals, nursing homes, and home health facilities. A review of literature indicated shift work, circadian rhythm interruptions and multiple stressors such as age, caring for children/aging parents and working multiple jobs may affect drowsy driving. Studies on global drowsy driving and cultural differences may affect international applicability. Further research was needed to better understand drowsy driving best practices, training modalities for health care workers, and developing a multidisciplinary collaboration between management and night-shift workers. Methods: A qualitative, exploratory multiple-case method was utilized. Registered and licensed practical nurses (N = 12) were interviewed. Results: Identified themes including three major themes emerged from the data analysis. 1) Fatigue is a significant challenge that impedes driving home safely. 2) Night nurses experience significant additional stressors relating to caring for family, school, and multiple jobs. 3) Multiple strategies are helpful, but they do not replace the body’s need for sleep. Strategies for managing drowsy driving and anxiety/stress producing issues were offered. Conclusions: Twelve-night shift workers shared the challenges drowsy driving and anxiety/stress producing issues outside of the work-related duties. Health care administrators may use the results to gain insight for training nurses for the night shift to prevent drowsy driving injuries and fatalities. The results of the study may offer a platform for further investigation that may uncover best-practice strategies for health care administrators staffing other types of 24-hour medical care facilities.

Thermal studies of individual Si/Ge heterojunctions — The influence of the alloy layer on the heterojunction

Abstract Phonon transport across an interface is of fundamental importance to applications ranging from electronic and optical devices to thermoelectric materials. The phonon scattering by an interface can dramatically suppress the thermal transport, which can benefit thermoelectric applications but create problems for the thermal management of electronic/optical devices. In this aspect, existing molecular dynamics simulations on phonon transport across various interfaces are often based on estimates of atomic structures and are seldom compared with measurements on real interfaces. In this work, planar Si/Ge heterojunctions formed by film-wafer bonding are measured for the interfacial thermal resistance ( R K ) that is further compared with predictions from existing simulations and analytical models. The twist angle between a 70-nm-thick Si film and a Ge wafer is varied to check the influence of the crystal misorientation. Detailed transmission electron microscopy studies are carried out to better understand the interfacial atomic structure. It is found that the alloyed interfacial layer with mixed Si and Ge atoms dominates the measured thermal resistance ( R K ) . Some oxygen impurities may also help to increase R K due to the formation of glassy structures. Following this, R K reduction should be focused on how to minimize the interdiffusion of Si and Ge atoms during the formation of a Si/Ge heterojunction.
Establishing Lot Size through Sanitation Clean Breaks in Produce Packing Facilities

A clean break is needed between groups of products for food protection regulators to consider produce as separate from other produce packed off the same line. Determining a clean break is important to limit the scope of a recall. Packers can determine lot size based on what is practical and the amount of risk that their business is comfortable with. Food protection regulators define lot size as when a clean break occurs before and after a group of products. For instance, if a packer chooses to have a daily documented and verified clean break, the packer would establish one lot per day, as defined by food protection regulators. In other situations, a packer may choose to have a clean break conducted weekly, meaning that a food safety incident could result in a week’s worth of production being recalled. This 2-page fact sheet was written by B. Chapman and M.D. Danyluk and published by the UF Department of Food Science and Human Nutrition, August 2013. http://edis.ifas.ufl.edu/fs234
AμT-driven Dynamic OCE: Review of Recent Progress (Conference Presentation)

This paper summarizes the latest results on acoustic micro-tapping (AμT) -based OCE and provides answers to several important questions related to dynamic elastography, including: what is the maximum spatial resolution that can be achieved in dynamic OCE? How should propagation speed be measured in soft tissue, especially in layered or bounded media? How can tissue elastic properties be properly reconstructed from experimental data? What is the potential for clinical translation, and what barriers remain?
Discrete Surface Ricci Flow for General Surface Meshing in Computational Electromagnetics Using Iterative Adaptive Refinement

We propose a surface meshing approach for computational electromagnetics (CEM) based on discrete surface Ricci flow (DSRF) with iterative adaptive refinement (AR) in the parametric domain for the automated generation of high-quality surface meshes of arbitrary element type, order, and count. Surfaces are conformally mapped by DSRF to a canonical parametric domain, allowing a canonical seed mesh to be mapped back to an approximation of the original surface. The new DSRF-based meshing technique provides a framework for generation of meshes with high element quality, aimed to greatly enhance the accuracy, conditioning properties, stability, robustness, and efficiency of surface integral equation CEM solutions. We demonstrate the ability of the proposed DSRF technique to produce meshes with near-optimal element corner angles for complicated, highly varied surfaces such as the NASA almond and a fighter jet model, using triangular, quadrilateral, and discontinuous quadrilateral elements. Other element types are also discussed. Where high-fidelity meshing is desired, the technique can capture fine-scale detail using very few high-order elements. Where low-fidelity meshing is desired, DSRF with AR can accurately recreate course-scale detail using standard first-order elements (e.g., flat triangular patches).
Hybrid vanadate silicon nanophotonic platform for extreme light management at telecom bands

We present a hybrid vanadate/silicon-photonics platform that integrates vanadate nanostructures with silicon-on-insulator (SOI) waveguides for high-performance functional passive building blocks at telecommunication wavelengths. Comprehensive numerical analysis is performed to study the mode hybridization in a hybrid waveguide structure that comprises a silicon ridge separated from a vanadate substrate. Studies on the impact of key geometric parameters reveal that the coupling between vanadate and photonic structures result in highly confined hybrid modes with extreme field confinement and significantly larger effective indices as compared to hybrid plasmon polarizations (HPPs) supported by noble-metal-based waveguiding systems. By leveraging the unique confinement and modal properties offered by vanadate material, we explore the feasibility of building ultra-compact waveguide attenuators and transverse-magnetic (TM)-pass polarizers based on proper combinations of vanadate and SOI configurations. Our studies indicate that a 5μm-long attenuator can simultaneously achieve over 30 dB absorption and a low optical return loss less than -27 dB for both transverse-electric (TE) and TM polarizations. In addition, through proper management of the interactions between vanadate and silicon modes with different polarizations, we numerically demonstrate an ultra-compact (3 μm) on-chip TM-pass polarizer featuring low insertion loss (~ 3 dB), in conjunction with an extinction ratio exceeding 22 dB. The integration of vanadate materials with SOI platforms thereby offers the potential to bridge a gap in conventional silicon photonic systems and opens new avenues towards scalable functional integrated silicon photonic devices at telecom bands.

Long-term Mortality After Nontraumatic Major Lower Extremity Amputation: A Systematic Review and Meta-analysis

Abstract Chronic wounds that lead to major lower extremity amputation have immense consequences on quality of life, and ultimately, mortality. However, mortality rates after lower extremity amputation for a chronic wound are broad within the literature and have escaped precise definition. This systematic review aims to quantify long-term mortality rates after major lower extremity amputation in the chronic wound population available in the existing literature. Ovid MEDLINE was searched for publications which provided mortality data after major, nontraumatic, primary lower extremity amputations. Lower extremity amputations were defined as below and above the knee amputation. Data from included studies was analyzed to obtain pooled 1-, 2-, 3-, 5- and 10-year mortality rates. Sixty-one studies satisfied inclusion criteria representing 36,037 patients who underwent nontraumatic major lower extremity amputation. Pooled mortality rates were 33.7%, 51.5%, 53%, 64.4%, and 80% at 1-, 2-, 3-, 5- and 10-year follow-up, respectively. Within the 8184 diabetic patients (types 1 and 2), 1- and 5-year mortality was 27.3% and 63.2%. Sources of mortality data were varied and included electronic medical records, national health and insurance registries, and government databases. Mortality after nontraumatic major lower extremity amputation is high, both in patients with diabetes as well as those without. Methods used to measure and report mortality are inconsistent, lack reliability, and may underestimate true mortality rates. These findings illustrate the need for a paradigm shift in wound management and improved outcomes reporting. A focus on amputation prevention and care within a multidisciplinary team is critical for recalcitrant ulcers.

In the Kingdom of Solovia: The Rise of Growth Economics at MIT, 1956-70

From its flow tide, fueled by the Cold War, to its ebbing with the anti-growth movement and the economic crises of the early 1970s, the “growthmen” of MIT stood at the center of the dominant field in macroeconomics. The history of MIT growth economics is traced from Robert Solow’s seminal neoclassical growth model of 1956 through the stabilization of growth theory in the first graduate textbooks.

Partisanship & nationalization in American elections: Evidence from presidential, senatorial, & gubernatorial elections in the U.S. counties, 1872–2020

Abstract Scholars argue that contemporary American elections are pronounced in their degree of partisanship and nationalization. While much of this work largely uncovers a heightened degree of nationalization in contemporary elections, little is known about how far back these patterns generalize. Given the limited availability of American electoral data, this work also generally focuses on a single office or during a certain segment of the post-war period since 1946. Moreover, this work largely focuses on states as salient units of analysis, masking potential variation found in U.S. counties, the smallest geographical unit constituting panel observations over time and across elections. In this note, we leverage a novel dataset of county-level election returns for President, U.S. Senate, and Governor, to specify a model assessing whether American elections are more nationalized and partisan than during any other period since the Civil War. We find evidence that presidential and Senate elections are more partisan today than any period since the Civil War, while gubernatorial elections are as partisan today as they were during the late 1800s. Our findings have implications for contemporary-based theories explaining the rise of partisanship in American elections and demonstrates the utility of county-level data in assessing electoral changes in America.

Decent work and physical health: A multi-wave investigation

Abstract The current study examined the links between decent work and three components of physical health (general health, health symptoms, health behaviors) with a sample of 569 employed adults. Data were gathered at three time points over a two-month period. Drawing from Psychology of Working Theory (PWT), survival need fulfillment and workplace fatigue (Wave 2) were positioned as mediating variables between decent work (Wave 1) and physical health outcomes (Wave 3). Hypotheses were partially supported. Decent work directly, and indirectly via workplace fatigue, predicted overall physical health; decent work predicted health symptoms indirectly via workplace fatigue; and decent work predicted heath behaviors indirectly via survival need fulfillment. Findings offer a more nuanced picture of how decent work connects to physical health. Specifically, for overall health and health symptoms, workplace fatigue appears to be the main connecting variable. Individuals working in jobs considered decent may be less likely to suffer workplace fatigue, and in turn, more generally healthy with less negative health symptoms. For healthy habits, such as diet and exercise, survival need satisfaction appears more salient. Meeting one's survival needs via work may help an individual have the time, and live in the type of environment, that more allows for access to a healthy lifestyle. Implications for research and practice are discussed.

The immobilized-enzyme stirrer: Part 2. Fluorimetric determination of ethanol with the use of immobilized alcohol dehydrogenase [1]

Abstract A novel fluorimetric method is described for the determination of ethanol by means of alcohol dehydrogenase immobilized on a stirrer. Ethanol is oxidized by alcohol dehydrogenase to aldehyde, with simultaneous conversion of NAD to NADH; the increase in fluorescence of NADH is measured at 465 nm (λex = 370 nm). The calibration curve is linear for ethanol concentrations up to 250 mg 100 ml . Deproteinization is required prior to the assay of blood samples; recoveries are 97–102.7%. Enzyme stability, reproducibility and selectivity are discussed.
Reinforcer magnitude and resistance to disruption of forgetting functions and response rates.

The present experiment investigated the effects of reinforcer magnitude on resistance to disruption of remembering and response rates. Pigeons were exposed to a variable-interval (VI), delayed-matching-to-sample (DMTS) procedure with two components (rich and lean, distinguished by differing discriminative stimuli and hopper presentation duration). Completion of a VI 20 s schedule resulted in DMTS trials. In a DMTS trial, a choice of one of two comparison stimuli resulted in food if the choice matched the color of the previously presented sample stimulus. Separable aspects of the forgetting functions (initial discrimination and rate of forgetting) were examined by determining accuracy across a range of delays. Response rates and accuracy were higher in the rich relative to the lean component during baseline, and were more persistent during disruptors (extinction and prefeeding). During DMTS trials, extinction decreased initial discrimination more in the lean than the rich component, but had no systematic effect on rate of forgetting. During prefeeding, the rate of forgetting increased more in the lean than the rich component, but initial discrimination was not systematically affected. These results show persistence of response rates and remembering are positively related to reinforcer magnitude. The type of disruptor also influences the way in which remembering is disrupted.
Yin and Yang

Yin and yang is a concept originated in China and widely embraced in other East Asian cultures. Yin (陰) represents shadow, and yang (陽) represents light. The light and shadow are used as a metaphor that represents how things that seem opposite in fact support each other and create a unity as a whole. As our experiences teach us, we can vividly recognize shadow when contrasted with light, and light can be vividly recognized when contrasted with shadow. Because of light, shadow appears, and because of shadow, light appears. This symbolizes the fact that our perception does not exist as an absolute entity, but in relation to a seemingly opposite entity. This concept of Yin and Yan is practically applied in Chinese medicine, architecture, furnishing (Feng Shui), martial arts, and many other cultural activities in Chinese and East Asian society, serving as an underlying philosophy widely shared by the people.

EL GERMEN DE UN NUEVO PROYECTO SOCIAL. LOS INTELECTUALES DE LAS REVISTAS PORTADA Y QUÉ PASA. 1969-1980*

En el siguiente articulo se abordan dos publicaciones, revista Portada y Que Pasa, fundadas por un cuerpo de intelectuales provenientes de un sector de la derecha. El analisis se inscribe en el contexto social, economico y politico que se derivo a partir de las transformaciones impulsadas por el centro y la izquierda chilena a fines de los sesenta y comienzos de los setenta. Destacamos que mediante estas revistas este cuerpo de intelectuales fue formulando, embrionariamente, un proyecto social que devino bajo el regimen dictatorial en el establecimiento del neoliberalismo y la nueva democracia autoritaria, protegida y tecnificada que anuncio el general Pinochet en Chacarillas en 1977
Comment on ’Controversy concerning the definition of quark and gluon angular momentum’ by Elliot Leader [PRD 83 , 096012 (2011)]

It is argued by the author that the canonical form of the quark energy-momentum tensor with a partial derivative instead of the covariant derivative is the correct definition for the quark momentum and angular momentum fraction of the nucleon in covariant quantization. Although it is not manifestly gauge invariant, its matrix elements in the nucleon will be non-vanishing and are gauge invariant. We test this idea in the path-integral quantization by calculating correlation functions on the lattice with a gauge-invariant nucleon interpolation field and replacing the gauge link in the quark lattice momentum operator with unity, which corresponds to the partial derivative in the continuum. We find that the ratios of three-point to two-point functions are zero within errors for both the u and d quarks, contrary to the case without setting the gauge links to unity.
Temporary Immigration, Involuntary Immigration, and Other Variations on the Standard Model

This chapter relaxes the implicit assumptions made in most immigration models, namely that people immigrate permanently and according to their own free will. Many immigrants end up returning to their native countries, either because they had explicitly decided earlier to be abroad only temporarily, or because changing circumstances led them to reverse an earlier decision to be abroad permanently. The second major issue covered in this chapter is forced, involuntary immigration. Finally, this chapter analyzes refugees, who are people seeking to escape especially threatening conditions in their native countries.
Customary Trade and the Complications of Consent

Global justice theorists have given much attention to corporations' purchases of state-owned natural resources controlled by dictators. These resources, the common argument goes, belong to the people rather than to those who exercise effective political power. Dictators who rely on violence to secure their political power and who sell state-owned natural resources without authorisation from their people, or from their people's elected delegates, are therefore violating their peoples' property rights. But many dictatorships also distribute natural resource revenue to the population, and stopping to purchase natural resources from them is therefore likely to produce relative deprivation for the people, even while increasing the chances of the people gaining control over their property. Given these circumstances, can corporations buying the people's natural resources from a distributive dictatorship appeal to the people's consent as justification for such purchases? I consider this question by inspecting three types of consent to which resource corporations might appeal. I show that, under the circumstances of natural resource trade with distributive dictatorships, none of these types of consent can obtain. Hence, resource corporations cannot appeal to popular consent to defend their transactions with distributive dictatorships.
Reduction of Verification Conditions for Concurrent System Using Mutually Atomic Transactions

We present a new symbolic method based on partial order reduction to reduce verification problem size and state space of a multi-threaded concurrent system with shared variables and locks. We combine our method with a previous token-based approach that generates verification conditions directly without a scheduler. For a bounded unrolling of threads, the previous approach adds concurrency constraints between all pairs of global accesses. We introduce the notion of Mutually Atomic Transactions (MAT), i.e., two transactions are mutually atomic when there exists exactly one conflicting shared-access pair between them. We propose to reduce the verification conditions by adding concurrency constraints only between MATs. Such an approach removes all redundant interleavings, thereby, achieves state reduction as well. We guarantee that our MAT-based reduction is both adequate (preserves all the necessary interleavings) and optimal (no redundant interleaving), for a bounded depth analysis. Our experimental results show the efficacy of our approach in reducing the state space and the verification problem sizes by orders of magnitude, and thereby, improving the overall performance, compared with the state-of-the-art approaches.
Lohman Receives 2013 Geodesy Section Award: Response

I am very honored to be this year's recipient of the AGU Geodesy Section Award. I was fortunate to begin my academic career at a time when there was an explosion of new data types and computational resources. I have been very pleased to watch this trend continue, with the ongoing support of new InSAR missions worldwide and renewed interest in the democratization of access to this data.
Chapter 2. Recent Progress in Corticotropin-Releasing Factor Receptor Agents

Publisher Summary This chapter presents an overview of recent progress in corticotropin-releasing factor (CRF) receptor agents. CRF is a neurohormone that appears necessary and sufficient for the organism to mount functional, physiological and endocrine responses to stressors. CRF receptors belong to the family of “gut-brain” neuropeptide receptors. Other typical members of this family are receptors for calcitonin, vasoactive intestinal peptide, parathyroid hormone, secretin, pituitary adenylate cyclase-activating peptide, glucagon, and growth hormone-releasing factor. The chapter documents recent progress toward the goal of assigning functional significance to endogenous CRF circuits in brain. It examines the state of the art regarding the growing array of pharmacological tools, including the most recently published small-molecule ligands, which are available for further probing the physiological significance of CRF system activation. Concepts related to functional significance of CRF receptors and CRF-binding protein are described. CRF binding-protein (CRF-BP) is described and CRF mutant mouse models are analyzed. CRF gene knockdown is elaborated and a discussion on human stress-axis pathophysiology is presented. CRF receptor and CRF-BP selective pharmacological tools are reviewed and details of construction of CRF peptide analogs are provided. Concepts related to in vivo efficacy profile of CRF receptor and CRFBP ligands are also discussed in the chapter.
Does Age And Gender "Really" Play A Role In Faculty’s Use Of Instructional And Assessment Technologies?

This paper examines the use of technology by faculty at the higher education level. The data used was from a case study of a liberal arts college in the Northeastern United States. It examines whether there is a difference in use of technology for assessment purposes and instructional purposes based on age or gender. This study found there is no significant difference between genders regarding their use technology for assessment or instructional purposes, nor was there a difference between age groups and their use of technology for assessment purposes. The data did reveal interesting indications that suggested the possibility of age influencing the degree to which technology is used for instructional purposes. Namely, educators above the age of 55 used technology more often than educators between the ages of 40 and 55.
Some Recent Observations of Occultations by the Moon

A program for the measurement of diffraction patterns resulting from the lunar occultations of stars was begun at the Lowell Observatory by Rakos (1964), resumed by him in 1967 and continued by Pettauer through the summer of 1969. The expected results were accurate timing of occultations and hence accurate position measurements, the discovery of close double stars, and the determination of stellar diameters. The author is continuing the program using new equipment designed by R. E. Nather of the University of Texas.
Exposing Scandals, Guarding Secrets: Manuel Buendia, Columnismo, and the Unraveling of One-Party Rule in Mexico, 1965-1984

On January 14, 1982, residents of Tula, Hidalgo, discovered the bodies of nine murdered men floating in a sewage drain emanating from Mexico City. All bore signs of gruesome torture. Red Cross workers soon located three more bodies, leading one reporter to describe the homicides as “the crime of the century.” Detectives initially asserted that the victims were drug traffickers who had been murdered by a rival gang. Manuel Buendia, in his weekday political column Red Privada, described the scene as “bloodcurdling,” employing his signature hard-boiled prose. Yet, the nation's most prominent journalist was referring not only to the gore, but also to his suspicions that police had committed the crime.
