Microwave conductivity and dielectric constant of (TMTTF)2X,X = SCN, ReO4, SbF6

Abstract Microwave conductivity (6.5 GHz) and dielectric constants for three tetramethyltetrathiafulvalene salts (TMTTF) 2 X, where X = SCN, ReO 4 , and SbF 6 are described. Good agreement is found between the high frequency data and the previously reported dc measurements. However, frequency dependence of the conductivity is observed below the anion ordering of (TMTTF) 2 SCN, and the microwave conductivity exceeds the dc value above the structureless transition of (TMTTF) 2 SbF 6 . This structureless transition of (TMTTF) 2 SbF 6 (T c = 154 K ) and of (TMTTF) 2 ReO 4 (T c = 220 K ) is reflected by a divergence of the dielectric constant contrasting with a stepwise decrease at the ordering of the ReO 4 anions (T c = 160 K ). These data support the pseudo-gap picture for the structureless transition and point out the similarity between the transition observed in (TMTTF) 2 SCN and the structureless transition.
Melting and solidification of a metal system in a rectangular cavity

Abstract The role of natural convection on solid-liquid interface motion during melting and solidification of Lipowitz metal in a rectangular cavity was studied. The measurements of both temperature distributions and temperature fluctuations were used as a qualitative indication of the natural convection flow regimes and structures of melt during phase transformation. The measured and predicted solid-liquid interface positions during solidification from below and above, as well as melting from above and below, show reasonably good correspondence. The suppression of natural convection in the Lipowitz metal, which is not taken into account in the model, leads to a slower rate of melting and a higher rate of freezing than that predicted.
The Rate Decision: Adjustable vs Fixed Rate Mortgages

Homebuyers and commercial real estate buyers who borrow funds using mortgages all must face the choice of whether to assume a fixed or an adjustable rate mortgage. Other mortgage forms with alternative characteristics are available, but the deciding question remains the same. Fixed rate mortgages never change over time, but have a high initial rate: adjustable rate, interest-only or hybrid mortgages begin with lower rates, but they change at fixed intervals over time. In contrast to professionals, consumers are often ill-equipped to understand the benefits and drawbacks of mortgage instruments. With poor product knowledge they may find the choice between fixed and variable rate mortgages overwhelming. They need help in making informed decisions. Giving the bulk of consumers the knowledge that a university level finance course conveys is not possible. Thus, there is a need for a simple applicable technique that can improve financial choice. This paper offers a straightforward forecasting model, to make the decision easier and relatively risk free. Adjustable mortgages are not always the best choice, especially in a rising interest rate market or one that has a strong possibility of rising. The model is a decision making tool that may help ordinary consumers make the best choice. Alternatively, mortgage company personnel may use the forecast to aid consumers in selecting the best mortgage.
Response to Angiotensin II–Induced Proliferation of Neonatal and Adult Rat Cardiac Fibroblasts

In response to Dr Lijnen’s letter,1 it is indeed the case that several reports focused on the proliferative effects of angiotensin (Ang) II on isolated adult rat cardiac fibroblasts vary widely in the magnitude of effect. We have studied the proliferative effects of Ang II on these cells for the past 5 …
Simple synthesis of 1,3-cyclopentanedione derived probes for labeling sulfenic acid proteins

Facile, two-step synthesis and kinetic characterization of new chemical probes for selective labeling of sulfenic acid (–SOH) in proteins are presented. The synthesis route relies on the simple and highly efficient Michael addition of thiol containing tags or linkers to 4-cyclopentene-1,3-dione, the unsaturated derivative of 1,3-cyclopentanedione.
Visualization of Fibrous and Thread-like Data

Thread-like structures are becoming more common in modern volumetric data sets as our ability to image vascular and neural tissue at higher resolutions improves. The thread-like structures of neurons and micro-vessels pose a unique problem in visualization since they tend to be densely packed in small volumes of tissue. This makes it difficult for an observer to interpret useful patterns from the data or trace individual fibers. In this paper we describe several methods for dealing with large amounts of thread-like data, such as data sets collected using knife-edge scanning microscopy (KESM) and serial block-face scanning electron microscopy (SBF-SEM). These methods allow us to collect volumetric data from embedded samples of whole-brain tissue. The neuronal and microvascular data that we acquire consists of thin, branching structures extending over very large regions. Traditional visualization schemes are not sufficient to make sense of the large, dense, complex structures encountered. In this paper, we address three methods to allow a user to explore a fiber network effectively. We describe interactive techniques for rendering large sets of neurons using self-orienting surfaces implemented on the GPU. We also present techniques for rendering fiber networks in a way that provides useful information about flow and orientation. Third, a global illumination framework is used to create high-quality visualizations that emphasize the underlying fiber structure. Implementation details, performance, and advantages and disadvantages of each approach are discussed
African American College Women’s Reflections on Physical Activity Involvement During Public School Years

The purpose of this study was to investigate 42 African American college women (AACW) enrolled in the basic physical education program at a southern university in the USA to discern their experiences and perspectives as related to their K-12 physical education program. Data were collected through a survey questionnaire instrument and interviews. Constant comparison method was used to analyze the data. The findings revealed AACW (a) to participate in many physical activities in elementary school, few in middle school, and fewer in high school fewer (b) to disengage from participation in physical activities, (c) to self-perceive as tomboys, (d) to self describe as intelligent, energetic, athletic in elementary, intelligent, growing emotional, popular in middle school, and independent, studious, and intelligent in high school, and (e) to be aware of racial-self in middle and high school.
A general performance model for mobile slotted ALOHA networks with capture

A general analytical model is proposed to evaluate the performance of a mobile slotted ALOHA network. Near-far effects are incorporated in the model (in an approximate way) by considering a multi-group system. The model approximates the network behavior by an iterative solution between multiple one dimensional Markov chains, one for each group. The model is quite broadly applicable since (1) different physical layer parameters, such as modulation and coding, are abstracted by a set of conditional success probabilities, and (2) different groups can have different link layer parameters, such as the probabilities of packet generation and retransmission. As an example, a 5-group system with fading is used to illustrate the usefulness of the proposed model. The agreement between the analytical and simulation results is good. It is found that the impact of the fading effect on network performance depends on the significance of the near-far effect. The problem of unbalanced throughput between near and far groups is solved by assigning different retransmission probabilities to different groups.
Holographic Fermi arcs and a d-wave gap

We study fermion correlators in a holographic superfluid with a d-wave (spin two) order parameter. We find that, with a suitable bulk Majorana coupling, the Fermi surface is anisotropically gapped. At low temperatures the gap shrinks to four nodal points. At high temperatures the Fermi surface is partially gapped generating four Fermi arcs.
Right juxtaposition and a tunnel between the atrial appendages in a patient with atrial septal defect and pulmonary valve stenosis.

A 13-month-old boy with a diagnosis of atrial septal defect and pulmonary valve stenosis was admitted for corrective surgery. Right juxtaposition of the atrial appendages with a tunnel between the atrial appendages was detected during the surgery. The patient was operated successfully and had an uneventful recovery. Once right juxtaposition of the atrial appendages has been identified, the possibility of a “tunnel” communication between the appendages must be considered and ruled out.
Cold-adapted tubulins in the glacier ice worm, Mesenchytraeus solifugus

Abstract Glacier ice worms, Mesenchytraeus solifugus and related species, are the only known annelids that survive obligately in glacier ice and snow. One fundamental component of cold temperature adaptation is the ability to polymerize tubulin, which typically depolymerizes at low physiological temperatures (e.g.,
Characterization of a 140Kd cell surface glycoprotein involved in myoblast adhesion

Two monoclonal antibodies that cause changes in the morphology of cultured chick myogenic cells have been described previously [8]. In this paper, these antibodies are shown to interact with the same 140Kd protein. The 140Kd protein has been further characterized as a cell-surface glycoprotein by lactoperoxidase-catalyzed iodinations and lectin affinity chromatography. The protein is resistant to digestion by trypsin and collagenase and has been shown to be unrelated to fibronectin by immunoprecipitation studies and by peptide mapping. A second protein, of approximately 170Kd MW; is also immunoprecipitated by the monoclonal antibodies. This protein is probably unrelated to the 140Kd protein since the peptide maps are quite distinct.
Drought induces spruce beetle (Dendroctonus rufipennis) outbreaks across northwestern Colorado

This study examines influences of climate variability on spruce beetle (Dendroctonus rufipennis) outbreak across northwestern Colorado during the period 1650 2011 CE. Periods of broad-scale outbreak reconstructed using documentary records and tree rings were dated to 1843-1860, 1882-1889, 1931-1957, and 2004-2010. Periods of outbreak were compared with seasonal temperature, precipitation, vapor pressure deficit (VPD), the Palmer Drought Severity Index (PDSI), and indices of ocean-atmosphere oscillation that include the El Nino Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), and Atlantic Multidecadal Oscillation (AMO). Classification trees showed that outbreaks can be predicted most successfully from above average annual AMO values and above average summer VPD values, indicators of drought across Colorado. Notably, we find that spruce beetle outbreaks appear to be predicted best by interannual to multidecadal variability in drought, not by temperature alone. This finding may imply that spruce beetle outbreaks are triggered by decreases in host tree defenses, which are hypothesized to occur with drought stress. Given the persistence of the AMO, the shift to a positive AMO phase in the late 1990s is likely to promote continued spruce beetle disturbance.
Spatial Economic Development, Education, and the New Poverty

At the time the Great Society programs were initiated, the people most likely to be impoverished were blacks, women, and the aged. Today the face of poverty in the United States has changed; the economic prospects of black males are somewhat improved, while children living in female-headed households and young people account for an increasing portion of the poor. Human-capital investment in these youth is crucial to increase opportunity and to reduce the poverty rate. This paper investigates the extent to which spatial economic development policies can help reduce this new poverty.
The egg production of a marine planktonic copepod in relation to its food supply: Laboratory studies1

Egg production by Paracalanus parvus, a particle-grazing copepod, was investigated in relation to its food supply. The concentration of available food (P) and the rates of ingestion (I) and egg production (B) were measured simultaneously at intervals of 6 h to 2 d for periods of 2-10 d. concentration, chemical composition (carbon and nitrogen), and species of phytoplankton were experimental variables. Egg production was related to the food ingested during the previous day. For one food type, I and B were rectilinear functions of P. The average maximum rates of ingestion and egg production were 1.1 ..mu..g N female /sup -1/d/sup -1/ and 53 eggs female /sup -1/d/sup -1/, equivalent to specific rates of 1.5 and 0.37 d/sup -1/. B was proportional to I below a critical ingestion rate, I/sub c/, and independent of I above I/sub c/. For II/sub c/, B.I/sup -1/ declined in terms of both carbon and nitrogen. These results, together with the ratio of C:N in particulate matter in the sea off southern California, suggest that nitrogen (hence protein) potentially limits egg production by adult female Paracalanus and that ingested carbon is used inefficiently.

Elastic Buffer Flow Control for On-Chip Networks

Networks-on-chip (NoCs) were developed to meet the communication requirements of large-scale systems. The majority of current NoCs spend considerable area and power for router buffers. In our past work, we have developed elastic buffer (EB) flow control which adds simple control logic in the channels to use pipeline flip-flops (FFs) as EBs with two storage locations. This way, channels act as distributed FIFOs and input buffers are no longer required. Removing buffers and virtual channels (VCs) significantly simplifies router design. Compared to VC networks with highly-efficient custom SRAM buffers, EB networks provide an up to 45 percent shorter cycle time, 16 percent more throughput per unit power, or 22 percent more throughput per unit area. EB networks provide traffic classes using duplicate physical subnetworks. However, this approach negates the cost gains or becomes infeasible for a large number of traffic classes. Therefore, in this paper we propose a hybrid EB-VC router which provides an arbitrary number of traffic classes by using an input buffer to drain flits facing severe contention or deadlock. Thus, hybrid routers operate as EB routers in the common case, and as VC routers when necessary. For this reason, the hybrid EB-VC scheme offers 21 percent more throughput per unit power than VC networks and 12 percent than EB networks.
Is Environmental Improvement in Automotive Component Design Highly Constrained

Summary This article investigates the influence of environmental, cost, and performance requirements on the design and management of automotive components through a case study involving instrument panels. To address the question of whether the environmental improvement of an instrument panel (IP) is highly constrained, a lifecycle inventory analysis is used to characterize the major environmental burdens associated with a generic IP defined from an average of three midsized vehicle models. A life-cycle cost analysis is also conducted to understand the market forces operating in the domains of the original equipment manufacturer; consumer; and end-of-life (EOL) vehicle managen. This study indicates that the existing set of environmental requirements, in conjunction with current cost drivers and the large set of manufacturing and use phase functional performance requirements, highly constrain opportunities for environmental improvement Specific improvement strategies-lightweighting, elimination of the painting operation, and reduction in material complexity-are examined in the context of existing system requirements. The near-term forecast for improvements is not optimistic. Innovation will continue in a slow and piecemeal fashion until requirements affecting the total vehicle system are significantly changed
Commercial Bank Non-Interest Fee Charges: Are Fee Charges Different Between Islamic Banks and Conventional Banks? Evidence from Bangladesh

In the Western world, consumers complain about the soaring of non-interest bank fees during the recent years, the post global financial crisis in particular. Commercial banks charge a variety of non-interest fees for their transactions. This paper empirically tests whether the free charges are significantly different between conventional commercial banks and interest free Islamic banks. The average noninterest expenses to assets are 0.017 and 0.011 for conventional banks and Islamic banks respectively. The paper finds, using parametric test and nonparametric tests, no significant differences in noninterest expenses between conventional banks and Islamic banks. The competitive banking market of Bangladesh, suggested by low Herfindahl-Hirschman Index, is an important factor for the equality of mean fee charges between the conventional banks and the Islamic banks.
A Note on Internal State Minimization in Incompletely Specified Sequential Networks

A step in state minimization requires the selection of a minimal class of compatible sets of internal states which covers the given machine and is closed. Grasselli and Luccio have presented a solution of this problem which has certain drawbacks. This paper presents a simpler and shorter algorithm, guaranteed to yield all solutions, based upon their work and that of Paull and Unger.

Measurement of tendon strain during muscle twitch contractions using ultrasound elastography

A 2-D strain estimation algorithm was used to estimate tendon strain from ultrasound data collected during muscle twitch contractions. We first used speckle tracking techniques to estimate frame-to-frame displacements of all pixels within a rectangular region of interest (ROI) positioned over a tendon. A weighted, least-squares approach was then solved for the displacements of the ROI endpoints that best fit the pixel displacements. We summed endpoint displacements across successive frames to determine the cumulative endpoint motion, which was then used to estimate the cumulative strain along the tendinous fibers. The algorithm was applied to ultrasound radiofrequency data, acquired at 74 frames per second over the tibialis anterior (TA) musculotendon junction (MTJ). The TA muscle was electrically stimulated with the subject holding voluntary preloads of 0%, 10%, 20%, 30%, 40%, and 50% of a maximum voluntary contraction (MVC). Peak tendon strains computed using elastography (0.06 to 0.80%) were slightly larger and occurred earlier (50-90 ms after stimulus) than calculations based on visual analysis of B-mode images. This difference likely reflected the more localized nature of the elastographic strain values. Estimates of the tangential elastic modulus (192 plusmn 58 MPa) were consistent with literature values obtained using more direct approaches. It is concluded that automated elastographic approaches for computing in vivo tendon strains could provide new insights into musculotendon dynamics and function.
Tympanic Membrane Grafting With AlloDerm

Objective/Hypothesis: The purpose of this work is to evaluate the performance of an acellular dermal allograft (AlloDerm; LifeCell Corp., The Woodlands, TX) in tympanic membrane (TM) grafting. Study Design: A retrospective review of 20 consecutive tympanoplasty surgeries using temporalis fascia and 20 consecutive procedures using AlloDerm. Methods: The charts of 20 consecutive adults who underwent tympanoplasty surgery were reviewed to evaluate graft take and hearing results. Similarly, 20 consecutive patients who had TM grafting with AlloDerm were reviewed. Pre- and postoperative air-bone gaps (ABG) at 500 Hz, 1000 Hz, 2000 Hz, and 4000 Hz were compared. Results: There were no graft failures in either the temporalis fascia group or the AlloDerm group. No statistically significant difference was noted in hearing results when comparing the residual conductive loss in both postoperative groups. Conclusions: AlloDerm is a suitable material for TM grafting. This product is especially valuable in revision surgery in which the availability of appropriate autologous grafting material is limited.
GIS-Enabled Desktop Software Development Pardigms

In the world of GIS enabled desktop software development, there are two commonly used development paradigms: the plug-in (or extension) approach and the standalone application approach. A plug-in based application runs on and interacts directly with a host application. Alternatively, standalone GIS-enabled software applications typically use modular GIS components and run independently of any host application. Each of these methods has its own advantages and disadvantages for both the end-user and the developer. Some of these are presented in this paper. Additionally, a case study is presented exploring both software development paradigms in the context of the MapWindow GIS open source software package.
A single cell multi-analysis system for electrophysiological studies

A micro analysis system for multi-purpose electrophysiological studies of single cells has been designed, fabricated, and characterized. The micro electrophysiological analysis system (/spl mu/-EPAS) contains multiple extracellular opposing electrode pairs that interface with a single cell inside an analysis cavity. These electrodes can be used for general single electrode extracellular stimulation/recording studies, dual electrode applications such as impedance spectroscopy, and for applications requiring a greater number of electrodes such as impedance tomography. Additionally, the analysis system contains a sealing/clamping mechanism and a backside extracellular reference electrode for patch clamping studies. The analysis cavities were designed in an array format for parallel analyses. Bovine chromaffin cells were used as a target to demonstrate and characterize the system. Using the integrated glass sealing ring, giga-seals were obtained on a population of chromaffin cells. The micro system generated maximum giga-seal resistances of 1.2G/spl Omega/ with non-sealed average cavity-to-backside resistances of 0.5M/spl Omega/. Furthermore, the cellular analysis system was demonstrated for electrical impedance spectroscopy on chromaffin cells over a range from 40.0 Hz to 1.0 MHz.
An Approach to Parallelizing Isotonic Regression

Isotonic regression is the problem of fitting data to order constraints. We demonstrate that the isotonic regression of a finite set of numbers Y can be obtained by decomposing Y into subsets, performing parallel isotonic regressions on each subset, then performing a trivial isotonic regression on the resulting combined set. Numerical experiments confirm the efficacy of this approach.

Response to Pashler et al. (2016)

ABSTRACTPashler, Rohrer, Abramson, Wolfson, and Harris (2016/this issue) in their critique of Chatterjee, Rose, and Sinha (2013) data argue that (a) large effect sizes in Study 1 and Study 2 undermine the credibility of the data; (b) in a lexical task that is part of Study 3, a concentration of participants in (5,0) and (0,5) benefit/cost word data points and the similarity of 9 neutral word responses at these points are extremely unlikely; and (c) there are apparent errors in the execution of Study 3. In this response, I examine these issues in detail. A recent review of money prime literature (Vohs, 2015) notes many effect sizes that are as big as or bigger than ours. Although 8 coding errors were discovered in Study 3 data and this particular study has been retracted from that article, as I show in this article, the arguments being put forth by the critics are untenable. For instance, my analysis shows that results hold even without the concentration of (5,0) and (0,5) participants, and I offer statist...
Can you judge a video game by its cover? An exploration of subjective impressions and viewing patterns

Studies have shown that first impressions of websites can lead to lasting opinions regarding usability and trustworthiness. However, little research has been conducted concerning first impressions of video games. In this study, 20 college-age students were asked to view and rate images of 48 game box covers after a brief exposure while their eye movement patterns were recorded. Results revealed that participants can reliably form different impressions (e.g., fun vs. boring) about certain video games based on a brief viewing of the game box cover. Analysis of eye tracking data revealed that participants viewed the front image, side title strip, and front game title the most. Relationships among the different subjective attributes (e.g., design quality, entertainment value) are reported.
PIV Measurements of Surge Incipience in a Ported Shroud Compressor

The range of operability of compressors in turbochargers is limited by surge. At low mass flow rate, surge is characterized by a breakdown of the incoming flow accompanied with large pressure fluctuations and the development of reversal flow. Part of the passive control strategies to increase the performances of compressors includes the implementation of a ported shroud. By releasing the reverse flow and preventing instabilities to occur, it has been demonstrated that larger range of operability could be achieved with minor negative impact on the compressor efficiency. The scope of this research is to study the effective operational range for a turbocharger with port shrouded compressor typically used in diesel engines. In order to better understand and control the surge phenomenon, it is important to identify the aerodynamic changes leading to stall and eventually surge. Particle Image Velocimetry (PIV) was performed at the inlet of the compressor to capture steady state and transient velocity in respectively stable and unstable regimes. Using the dynamic signature of the compressor outlet pressure, it has been possible to phase lock the PIV measurements and reconstruct the evolution of the flow patterns along a full surge cycle. Specific emphasis was given to the understanding of how the ported shroud helps to prevent surge from occurring by comparing different operating conditions. In this paper, both standard 2D-PIV and stereoscopic 3D-PIV measurements are presented and permitted to characterize the flow interactions at the entrance of the compressor.
A Comparison of Growth and Developmental Rates of the Parasite Hyposoter exiguae Reared from Two Instars of its Host, Trichoplusia ni,

Developmental rate and size of Hyposoter exiguae (Viereck) (Ichneumonidae) were determined in both early and late instar Trichoplusia ni (Hubner) (Noctuidae) larvae. Four larval instars were observed, each lasting about 2, 1½, 1½, and ½ days, respectively. At 26°C, development from egg to adult required 14 days in both 2nd and 4th instar hosts. Parasite larvae and adults reared on 4th instar hosts were significantly larger than those reared on 2nd instar hosts. Larval development progressed continuously throughout all instars, but developmental rate within each depended upon host instar attacked. First and 2nd instar parasites developed faster in older hosts, but 3rd instar developmental rates were about equal. During the parasite's final instar, developmental rate was slower in 4th instar hosts. Larval developmental time ranged from 6½ to 7½ days.

THE EFFECT OF FLOWER PRODUCTION ON MALE REPRODUCTIVE SUCCESS IN WILD RADISH POPULATIONS.

Flower production is the major determinant of pollen yield and an important component in pollinator attraction. Consequently differences among plants in flower production are expected to have a substantial impact on their relative success at fathering seed. We examined this prediction using one natural and three structured populations of wild radish. We found that a plant's relative success at fathering seed on another plant in the population (male fertility) increased with flower production. Nonetheless, the increase in fertility exhibited a diminishing marginal gain, with the relationship varying among populations. The relationship between the estimates of total number of seeds sired and flower production varied substantially among the populations examined, ranging from a weakly linear to strongly negative quadratic. Not surprisingly, the spatial structure of the population with respect to seed yield had a powerful effect on the total number of seeds sired because male fertility decreased exponentially with intermate distance. This exponential relationship occurred in all populations examined. Other covariates important to male fertility were flower color, time, the specific identity of the male parent, and male by female interaction. The identity of the male parent consistently accounted for a large portion of the variation in male fertility, indicating that other unmeasured features of the plant influenced its success.

E-087 negative predictive value of ct perfusion in excluding lesions amenable to endovascular reperfusion

Purpose To determine the negative predictive value of CT perfusion (CTP) imaging in excluding lesions amenable to endovascular reperfusion in patients who present with symptoms of acute ischemic stroke. Materials and methods We retrospectively reviewed CTP studies performed between February 2013 and February 2015 who had follow up MRI imaging within 10 days. Patients who received intervenous thrombolysis were excluded. True negative was defined as a CTP study that had: no perfusion mismatch, a fixed matched defect or a small perfusion mismatch in a size (typically Results 461 CTP studies performed in 450 patients (mean age 69.1 years, 57% male) were reviewed. 400 were true negative, 55 were true positive, 6 were false positive and 0 was false negative. Negative predictive value was 100%. Conclusion CTP can confidently exclude lesions which are not amenable to endovascular reperfusion. Disclosures M. Chehab: None. J. Wilseck: None.
Dynamics of Barrier Crossings for the Generalized Anderson-Holstein Model: Beyond Electronic Friction and Conventional Surface Hopping.

We investigate barrier crossings within the context of the Anderson–Holstein model, as relevant to coupled nuclear–electronic dynamics near a metal surface. Beyond standard electronic friction or conventional surface-hopping dynamics, we show that a broadened classical master equation can recover both the correct nonadiabatic and the correct adiabatic dynamics for a general escape problem (even with possibly multiple escape channels). In the case of a large barrier with only a single escape channel, we also find a surprising conclusion: electronic friction can recover Marcus’s nonadiabatic theory of electron transfer in the limit of small molecule–metal couplings. The latter conclusion establishes a hidden connection between Marcus’s nonadiabatic theory and Kramer’s adiabatic theory of rate constants.
PD-L1, PD-L2 and PD-1 expression in metastatic melanoma: Correlation with tumor-infiltrating immune cells and clinical outcome

ABSTRACTTherapeutic blockade of PD-1/PD-L1 can have dramatic therapeutic benefit in some patients; however, the prognostic associations of PD-1 and its ligands, in the absence of therapeutic blockade have not been definitively addressed. In particular, associations of PD-L2 with immune infiltrates and with outcome have yet to be explored. We hypothesized that surface expression of both PD-L1 and PD-L2 by melanoma cells would be associated with immune cell infiltration and with overall patient survival, independent of checkpoint blockade therapy. We also characterized the heterogeneity of their distribution within a tumor and within tumors of the same patient. Tissue microarrays of metastatic melanoma samples from 147 patients were quantified for CD8+, CD45, CD4+, CD3, CD163, CD20, CD138, FoxP3, PD-1, PD-L1 and PD-L2 markers by immunohistochemistry. Relationships between the proportions of PD-L1 and PD-L2 expressing tumor cells with the immune cell count, distribution (immunotype) and patient survival were...
Developing leadership competencies among medical trainees: five-year experience at the Cleveland Clinic with a chief residents' training course.

Objectives:Challenges in healthcare demand great leadership. In response, leadership training programs have been developed within academic medical centers, business schools, and healthcare organizations; however, we are unaware of any well-developed programs for physicians-in-training.Methods:To address this gap, we developed a two-day leadership development course for chief residents (CRs) at the Cleveland Clinic, framed around the concept of emotional intelligence. This paper describes our five-year experience with the CRs leadership program.Results:Since inception, 105 CRs took the course; 81 (77%) completed before-and-after evaluations. Participants indicated that they had relatively little prior knowledge of the concepts that were presented and that the workshop greatly enhanced their familiarity with leadership competencies. Qualitative analysis of open-ended responses indicated that attendees valued the training, especially in conflict resolution and teamwork, and indicated specific action plans fo...
Motor output oscillations with magnification of visual feedback in older adults.

Abstract Magnification of task visual feedback increases force variability in older adults. Although the increased force variability with magnified visual feedback in older adults relates to the amplification of oscillations in force below 0.5 Hz, the related frequency modulation in muscle activity remains unknown. The purpose of this study, therefore, was to characterize the oscillations in muscle activity that contribute to the amplification of force variability with magnified visual feedback in older adults. Fifteen older adults (76.7 ± 6.4 years, 7 females) performed isometric contractions at 15% of maximal voluntary contraction (MVC) with ankle dorsiflexion with low-gain (0.05°) or high-gain visual feedback (1.2°). The standard deviation (SD) of force increased significantly (55%) from low- to high-gain visual feedback condition ( P P > 0.5). The increase in force variability was related to greater power in force oscillations from 0 to 0.5 Hz (R 2 = 0.37). The increase in force oscillations was associated with greater power in EMG burst oscillations from 0.5 to 1.0 Hz (R 2 = 0.50). In conclusion, these findings suggest that magnification of visual feedback alters the modulation of the motor neuron pool in older adults and exacerbates force variability by increasing the oscillations in force below 0.5 Hz.
Chapter 1 – Forecasting Inflation

This chapter discusses recent developments in inflation forecasting. We perform a horse-race among a large set of traditional and recently developed forecasting methods, and discuss a number of principles that emerge from this exercise. We find that judgmental survey forecasts outperform model-based ones, often by a wide margin. A very simple forecast that is just a glide path between the survey assessment of inflation in the current-quarter and the long-run survey forecast value turns out to be competitive with the actual survey forecast and thereby does about as well or better than model-based forecasts. We explore the strengths and weaknesses of some specific prediction methods, including forecasts based on the Phillips curve and based on dynamic stochastic general equilibrium models, in greater detail. We also consider measures of inflation expectations taken from financial markets and the tradeoff between forecasting aggregates and disaggregates.

The Psychotherapy of Alcoholic Women

The population of female alcoholics in the United States is large and possibly increasing. It is estimated that a minimum of 20% of the alcoholics in this country or one million of the estimated five million American alcoholics are women (Beckman, 1975). The number may be even higher, as the ratio of female to male alcoholics appears to be largely a function of the subsample from which it is drawn. Hence, this ratio may vary from 1 female to 11 males in prison populations (Jones, 1971) to a 1-to-1 male-female ratio in private hospital or private practice settings (Lindbeck, 1972; Tamerin, Tolor, and Harrington, 1976).
Using Board Games as Subject Matter for Developing Expertise in Model-Based Systems Engineering

As more organizations transition from traditional document-centric systems engineering to a model-based approach, many are challenged to train their staff in new languages, tools, and methodologies, while managing the expectations of stakeholders and their expected model outcomes. In particular, challenges associated with learning a new modeling language and developing skills in the 'art' of modeling present organizations with formidable obstacles to realizing this transition. This paper hypothesizes that systems engineers may more readily learn how to correctly model with SysML, and develop intuition about the art of modeling and using patterns, if their learning references a commonly and thoroughly-understood subject, such as a board game. This paper presents a case for the use of board games as subject matter for new modelers. It demonstrates the concept with a sample model of Hasbro's popular board game, Monopoly, and discusses the limitations of this approach and potential adaptations that may broaden the applicability of the learned skills to projects. Finally, results from a small feasibility assessment and concepts for more formal study to evaluate the hypothesis are presented.

Are Information Seekers and Users Among the General Public at a Crossroads?: An Examination of the Quantity of Consumer Health Publications on Eating Disorders in Popular Magazines and on the Internet in 1998

Presently, eating disorders affect millions of people. Today, the media and the Internet are major publishing channels for consumer health information. Much research has found that the media may offer insufficient information on eating disorders. This research examines the quantity of adult consumer health publications on eating disorders in magazine articles and on the Internet in 1998 and investigates the effectiveness of Internet search engines. The results indicate that the resources found in popular magazines and on the Internet are not adequate, and that the Internet search engines are not effective in searching for information.
‘Re-occupying the State’: Social Housing Movement and the Transformation of Housing Policies in Taiwan

Since the late 1980s, the process of democratization and increased public participation has pressed for the expansion of social welfare in Taiwan, while neoliberalization has affected housing policies to enhance the operation of market mechanisms for housing provision. Nowadays, the Taiwanese state primarily facilitates the growth of housing market and homeownership, exercising little control over speculation. Escalating housing prices have led to a strong social rental housing movement. This chapter explores the diminishing role of the state in Taiwan’s housing system and how housing has been understood by the state, placing the discussions in the political and economic contexts after 1949. The chapter also examines how the social housing movement since 2010 has gradually transformed the role of the state in its provision of housing and what obstacles the movement has to confront.
On the uncertainty of temperature estimation in a rapid compression machine

Abstract Rapid compression machines (RCMs) have been widely used in the combustion literature to study the low-to-intermediate temperature ignition of many fuels. In a typical RCM, the pressure during and after the compression stroke is measured. However, measurement of the temperature history in the RCM reaction chamber is challenging. Thus, the temperature is generally calculated by the isentropic relations between pressure and temperature, assuming that the adiabatic core hypothesis holds. To estimate the uncertainty in the calculated temperature, an uncertainty propagation analysis must be carried out. Our previous analyses assumed that the uncertainties of the parameters in the equation to calculate the temperature were normally distributed and independent, but these assumptions do not hold for typical RCM operating procedures. In this work, a Monte Carlo method is developed to estimate the uncertainty in the calculated temperature, while taking into account the correlation between parameters and the possibility of non-normal probability distributions. In addition, the Monte Carlo method is compared to an analysis that assumes normally distributed, independent parameters. Both analysis methods show that the magnitude of the initial pressure and the uncertainty of the initial temperature have strong influences on the magnitude of the uncertainty. Finally, the uncertainty estimation methods studied here provide a reference value for the uncertainty of the reference temperature in an RCM and can be generalized to other similar facilities.

A Model Program for the Success of College Students with Attention and Learning Disorders

Internationally, institutions of higher education have been called upon to engage college students with learning disabilities in campus life, to provide effective learning supports, and to hold high expectations (Tinto, 2012). Model programs providing comprehensive support to college students with learning disabilities are few and far between. As the number of college students needing learning support increases across many countries, there is a critical demand to identify programs and approaches that produce optimal outcomes for students. This article provides an overview of the legal structures on which supports for individuals with disabilities are based in the United States in comparison to Italy. For nearly forty years, a U.S. program called Strategic Alternative Learning Techniques (SALT) Center has extended federally mandated supports in to higher education. As Italy grows its tertiary programs and supports for students with learning disabilities, the SALT Center may serve as a helpful model program.
