Comparison of Measurements of Atmospheric Wet Delay by Radiosonde, Water Vapor Radiometer, GPS, and VLBI

Abstract The accuracy of the Global Positioning System (GPS) as an instrument for measuring the integrated water vapor content of the atmosphere has been evaluated by comparison with concurrent observations made over a 14-day period by radiosonde, microwave water vapor radiometer (WVR), and Very Long Baseline Interferometry (VLBI). The Vaisala RS-80 A-HUMICAP radiosondes required a correction to the relative humidity readings (provided by Vaisala) to account for packaging contamination; the WVR data required a correction in order to be consistent with the wet refractivity formulation of the VLBI, GPS, and radiosondes. The best agreement of zenith wet delay (ZWD) among the collocated WVR, radiosondes, VLBI, and GPS was for minimum elevations of the GPS measurements below 10°. After corrections were applied to the WVR and radiosonde measurements, WVR, GPS, and VLBI (with 5° minimum elevation angle cutoff) agreed within ∼6 mm of ZWD [1 mm of precipitable water vapor (PWV)] when the differences were averaged,.
Peripheral nerve stimulation properties of head and body gradient coils of various sizes

Peripheral nerve stimulation (PNS) caused by time‐varying magnetic fields has been studied both theoretically and experimentally. A human volunteer study performed on three different body‐size gradient coils and one head‐size gradient coil is presented in this work. The experimental results were used to generate average PNS threshold parameters for the tested gradient systems. It was found that the average stimulation threshold increases while gradient‐region‐of‐uniformity size decreases. In addition, linear relationships between PNS parameters and diameter of homogeneous gradient spherical volume (DSV) were discovered: SRmin and ΔGmin both vary inverse linearly with DSV. More importantly, the chronaxie value was found to vary inversely linearly with the DSV. This finding indicates that, contrary to the general understanding, the parameter “chronaxie” in the commonly accepted simple stimulation models cannot be considered to be a single‐value, nerve‐specific constant. A modified linear model for gradient‐induced PNS based on these results was developed, which may permit, for the first time, the general prediction of nerve stimulation properties for gradient coils of arbitrary linear region dimension.

Fault tolerant in-wheel motor topologies for high performance electric vehicles

The use of in-wheel motors, often referred to as hub motors, as a source of propulsion for pure electric or hybrid electric vehicles has recently received a lot of attention. Since the motor is housed in the limited space within the wheel rim, it must have a high torque density and efficiency, and survive the rigours of being in-wheel in terms of environmental cycling, ingress, shock and vibration and driver abuse. Finally, to ensure adequate levels of functional safety are met it is essential that failures do not lead to loss of control of the vehicle. This paper presents studies of a fault tolerant concept for the design of in-wheel motors. The study focused on achieving a high torque density and the ability to sustain an adequate level of performance following a failure. A series of failures are simulated and then compared with experimental tests on a demonstrator motor.
Functional Representation of 3d Space in Endogenous Attention Shifts

The aim of this study was to explore whether the attentional system, as far as an endogenous orienting is concerned, allocates resources along the sagittal plane and whether such a process is affected by, and is likely to be based on, different functional representations of 3D space in the brain. Several models make a main action-based distinction between representations of peripersonal space and of those extrapersonal space. Accordingly, if attention has to move from one representation to another, it should be possible to observe a decrease in performance during such a transition. To test this hypothesis three experiments were run in which participants performed a cued detection task. Cue stimuli were informative and were centrally located around the fixation point. Target stimuli were displayed at four different depth planes. In the first experiment, assuming that the border between the peripersonal space and the extrapersonal space was at 1 m from the observer, half the target stimuli were located in the peripersonal space and half in the extrapersonal space. The fixation point was located at 1 m from the observer. In the second experiment, the fixation point was moved at 2 m from the observer in order to rule out the possible effects of ocular motor programming. In the third experiment, in order to rule out effects related to the spatial layout of target stimuli (i.e., centre of mass effect) two target stimuli were located in the peripersonal space and six in the extrapersonal space. In all the experiments, besides a validity effect, we observed greater reaction times when attention shift was across spatial representations than when it was within the same representation. The implications for action-oriented models of attention are discussed.
The Effects of Life Domains on Cyberbullying and Bullying: Testing the Generalizability of Agnew’s Integrated General Theory

In 2005, Robert Agnew published his book Why Criminals Offend in which he synthesized an array of theoretical predictors of crime and delinquency into a parsimonious integrated general theory. He argued that delinquency is influenced by mechanisms found in five distinct life domains: self, family, peer, school, and work. Using longitudinal data from South Korea, the current research tested the generalizability of Agnew’s theory by applying it to bullying and cyberbullying. Results from a negative binomial regression model provided mixed support for Agnew’s theory as a general theory of crime. The significant effects of life domains were found to differ across types of bullying.
Comparative study of the PD-L1 status between surgically resected specimens and matched biopsies of NSCLC patients reveal major discordances: a potential issue for anti-PD-L1 therapeutic strategies.

BACKGROUND High expression of programmed death ligand-1 (PD-L1) on tumor cells (TC) and/or on tumor-infiltrating immune cells (IC) is associated with a high response rate in patients with advanced nonsmall-cell lung cancer (NSCLC) treated with PD-L1 inhibitors. The use of a PD-L1 immunohistochemical (IHC) test in determining the responsiveness to immunotherapy has raised the question of the reliability and reproducibility of its evaluation in lung biopsies compared with corresponding resected surgical specimens. PATIENTS AND METHODS PD-L1 expression in TC and IC was assessed in 160 patients with operable NSCLC on both whole surgical tissue sections and matched lung biopsies, by using a highly sensitive SP142 IHC assay. The specimens were scored as TC 0-3 and IC 0-3 based on increasing PD-L1 expression. RESULTS PD-L1 expression was frequently discordant between surgical resected and matched biopsy specimens (the overall discordance rate = 48%; 95% confidence interval 4.64-13.24) and κ value was equal to 0.218 (poor agreement). In all cases, the biopsy specimens underestimated the PD-L1 status observed on the whole tissue sample. PD-L1-positive IC tumors were more common than PD-L1-positive TC tumors on resected specimens. The discrepancies were mainly related to the lack of a PD-L1-positive IC component in matched biopsies. CONCLUSIONS Our results indicate relatively poor association of the PD-L1 expression in TC and IC between lung biopsies and corresponding resected tumors. Although these results need to be further validated in larger cohorts, they indicate that the daily routine evaluation of the PD-L1 expression in diagnostic biopsies can be misleading in defining the sensitivity to treatment with PD-L1 targeted therapy.
The Compressive Matched Filter

The recently introduced theory of compressed sensing enables the reconstruction of sparse or compressible signals from a small set of nonadaptive, linear measurements. If properly chosen, the number of measurements can be much smaller than the number of Nyquist rate samples. Interestingly, it has been shown that random projections are a satisfactory measurement scheme. This has inspired the design of physical systems that directly implement similar measurement schemes. However, despite the intense focus on the reconstruction of signals, many (if not most) signal processing problems do not require a full reconstruction of the signal – we are often interested only in solving some sort of detection problem or in the estimation of some function of the data. In this report, we show that the compressed sensing framework is useful for a wide range of statistical inference tasks. In particular, we demonstrate how to solve a variety of signal detection and estimation problems given the measurements without ever reconstructing the signals themselves. For this purpose we introduce the compressive matched filter. We provide theoretical bounds along with experimental results.
AgNOR polymorphism association with squamous intraepithelial lesions and invasive carcinoma with HPV infection.

OBJECTIVE Evaluate the relationships between AgNORs polymorphisms and squamous intraepithelial lesions (SIL) and squamous cell carcinoma (SCC) with HPV infection. MATERIALS AND METHODS A study was carried out on sixty women from the state of Guerrero, Mexico. HPV detection was performed by PCR. AgNORs were identified by argentic impregnation. One hundred cells per slide were counted and classified according to the polymorphism of AgNORs dots; typical (spherical) and atypical (large, kidney-shaped and clustered). RESULTS A total of 100% of the cases were positive for HPV infection. Nine different high-risk HPV genotypes were found, type 16 was the most common (48.6%). The AgNORs showed a significant decrease in spherical shape according to neoplastic development. The three atypical shapes showed a significant increase in SIL and SCC (p-trend<0.001). CONCLUSIONS AgNORs polymorphism rises progressively according to the grade of histological lesions that can be useful as a prognosis for progression of SCC.
Trading Places: An Experimental Comparison of Reallocation Mechanisms for Priority Queuing

In a laboratory experiment, we compare two auction mechanisms that determine the sequence of service to queued customers. In the server-initiated auction, the server, when idle, sells the right to be served next to the highest bidding customer in the queue and distributes the proceeds among the remaining customers. We show that this mechanism has an efficient equilibrium. In the customer-initiated auction, new arrivals can sequentially trade places with queued customers. This mechanism does not have an efficient equilibrium. We use two novel experimental protocols to examine the behavioral properties of both auction mechanisms. We find that, on average, the server-initiated auction and the customer-initiated auction perform equally well in terms of efficiency gain. Moreover, participants indicate that they find the server-initiated auction a fairer mechanism than the customer-initiated auction. When voting between the two auctions, participants tended to favor the server-initiated auction. We also find evidence of endowment and sunk-cost effects, which partially explains deviations from standard theory predictions.
In life and in death: the story of people living with metastatic cancer

ABSTRACT Advances in the treatment of metastatic cancers such as melanoma enable patients to live for many years. However, melanoma patients are under constant threat of a recurrence or a new growth, are under intensive follow-up, and must avoid exposure to the sun. These factors engender anxiety, a constant fear of recurrence, and a reduction in routine activity, thus requiring patients to develop mechanisms for coping simultaneously with the illness and the threat of death. This study uses content analysis of the documentation of a support group for metastatic melanoma patients to examine how they cope with both. The findings suggest that they are able to cope with both simultaneously. However, perhaps because they recognise their total lack of control over the illness, they exercise control in how they cope with death. The findings suggest that support groups like the one documented in this article could serve as sheltered and effective therapeutic spaces for coping with the threat of death.
Evaluation of Systemic Markers Related To Anemia of Chronic Disease in the Peripheral Blood of Smokers and Non-Smokers with Chronic Periodontitis

Objectives The aim of this study was to investigate the effect of cigarette smoking on clinical parameters and signs anemia of chronic disease in chronic periodontitis patients. Methods The study base consisted of 88 patients with chronic periodontitis including 45 volunteer current smokers with age range of 30–69 (45.5±8.5) and 43 volunteer non-smokers with age range of 32–61 years (45.8±7.9). The clinical parameters including plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment loss (CAL) were recorded and several red blood cell parameters were determined from peripheral blood samples. Results In smokers, PI, PD and CAL were significantly higher than non-smokers (P<.05). The number of erythrocytes and the levels of hemoglobin, hematocrit and iron were lower in smokers compared to non-smokers (P<.05). Conclusions In the present study, it is concluded that cigarette smoking may be effective on the signs of anemia of chronic disease in patients with chronic periodontitis.
Expectancy-Based Model of Melodic Complexity

1 Background According to Berlyne (1971), preference for stimuli is related to their complexity or unpredictability. Although this claim has been supported by a large number of studies in the field of music (reviews by Finnas, 1989; and Fung, 1995; North & Hargreaves, 1995), adequate objective ways of measuring the originality or complexity of music are in short supply. The existing objective measurements, such as the information-theoretic and tone transition probability (Simonton, 1984) models possess well-known limitations: First, research within this tradition has tended to employ limited stimuli, which have typically been specially-composed pieces or excerpts of classical music. Secondly, these models do not address the role of the listener's perceptual system in organising the structural characteristics of music. Therefore the aim of the present research was to (i) devise an objective computer model of those perceptual processes which underlie human listeners' musical expectations and complexity judgements; (ii) determine the extent to which this model could predict experimental participants' complexity judgements in response to a range of musical stimuli; (iii) determine the effectiveness of the model relative to that of the previous models; and (iv) provide an example of the model's application to real music.
The implementation of Section 5(4) of the Mental Health Act 1983.

Section 5(4) (nurse's holding power) of the Mental Health Act 1983 empowers mental health nurses to legally prevent an informal in-patient from leaving hospital for up to six hours. The section may be applied for the patient's health or safety or the protection of others. Since its introduction in September 1983 there have been 34,000 applications of the section, an average of 1460 per annum. The application of Section 5(4) is likely to: lead to further detention under the Act; have implications for the practice of nurses; and affect the care received by patients in the aftermath of its use. However, the literature review revealed a paucity of research on the subject. The existing research has focused on three main areas: nurses' opinions of their holding power; their knowledge of Section 5(4); and trends associated with the implementation of the section. However, no attempts have been made to examine the events before, during and after the implementation of Section 5(4). This qualitative study sought to address this deficit by examining why and how Section 5(4) was implemented from the perspective of the nurses and patients involved in the process.A collective case study approach was utilised to generate data from one mental health NHS Trust over a period of one year. Data were generated from three sources: archival (statistical) records on 803 applications of the section; documentary accounts of the detention process, for example nursing notes; and interviews with 30 nurses and four patients. Within- and cross-case narrative analysis was undertaken on the data set. The method of narrative analysis employed was developed specifically for this study.The analysis produced a six-part typology of nurses' stories that explained why Section 5(4) was implemented. The six types were: 'health, safety or protection'; Tack of knowledge'; 'catalyst'; 'medical inaction'; 'self-protection'; and 'last resort'. The analysis also constructed a collective story of nurses' experiences that identified the key stages in the detention process. Stories were also constructed from patients' experiences of being detained. These stories generated in-depth accounts of patients' admission to hospital, the events leading up to their detention, the implementation of Section 5(4), and the aftermath of their experiences.The implications of the study's findings are considered for education, policy, practice and research and focus on four main areas: informal admission to hospital; information giving; reasons for implementing Section 5(4); and the consequences of the detention for both nurses and patients.
Cognitive and affective correlates of reproductive hormones

Cognitive and Affective Correlates of Reproductive Hormones by Chandler Marrs Dr. Douglas Ferraro, Examination Committee Chair Professor of Psychology University of Nevada, Las Vegas Approximately 80% of all women experience considerable mood lability in the days and weeks following parturition. Many researchers have attempted and failed to link postpartal mood changes to reproductive hormones and very little research examines perinatal cognitive ability. The goal of this research was to elucidate the pattern of cognitive and affective behaviors associated with the elevated hormones of pregnancy and the diminished hormones following parturition. The present study compared salivary progesterone, dehydroxyepiandrosterone (DHEAS), estrone, estradiol, estriol and testosterone with the results from a battery of neuropsychiatrie assessments administered to thirty-two healthy, primigravid women at 37 weeks of pregnancy and within the first 10 days postpartum. Results from this study indicate that cognitive performance is impaired across multiple domains both during pregnancy and following parturition. Moreover, perinatal mood is adversely related to diminished late pregnancy testosterone levels followed by postpartal increases in DHEAS.
Quasi-experimental research in culture sensitive psychology

The research presented in this article follows up on several aspects of Gustav Jahoda’s long and fruitful career: (1) his early fieldwork on cognitive development in Africa, particularly in the area of spatial skills; (2) his interest in cross-cultural psychology as a research method; and (3) his insistence on bringing anthropology and psychology together. The topic of our research is the development of a so-called “geocentric” frame of spatial reference. This is a cognitive style, in which individuals describe and represent small-scale table-top space in terms of large-scale geographic dimensions. We explore the development with age of geocentric language and cognition, and the relationships between the two. We also explore the many environmental and socio-cultural variables that favor the use of this frame. We demonstrate how we untangled several of these variables by using a succession of within-society group comparisons, in several societies where a geocentric frame is in common usage (Bali, Indonesia, India, and Nepal). Our research program unfolds like a detective story, where one finding that is difficult to interpret because of several confounded variables leads to another quasi-experimental group comparison that suggests another hypothesis, which is then tested in a further session of field-work. In each case, we emphasize how important it was to have extensive linguistic and ethnographic knowledge before implementing psychological tests. The research design is not cross-cultural as such (we hardly ever perform comparisons between societies), but culturally sensitive within a series of societies; in other words, as Dasen and Jahoda (1986, p. 413) defined it, “cross-cultural developmental psychology is not just comparative: essentially it is an outlook that takes culture seriously. ”
Exhaustive submaximal endurance and resistance exercises induce temporary immunosuppression via physical and oxidative stress

Regular running and strength training are the best ways to improve aerobic capacity and develop the size of skeletal muscles. However, uncontrolled physical activities can often lead to an undertraining or over-training syndrome. In particular, overtraining causes persistent fatigue and reduces physical performance due to changes in the various physiological and immunological factors. In this study, we gave an exhaustive submaximal endurance or resistance exercise to participants and investigated the relationship between physical stress (cortisol level in blood), oxidative stress (intracellular ROS accumulation), and adaptive immune response (CD4:CD8 ratio). Materials and Methods Ten male volunteers were recruited, and performed a submaximal endurance or resistance exercise with 85% of VO2max or 1-repetition maximum until exhaustion. Blood samples were collected at rest, and at 0 and 30 min after the exercise. Cortisol levels, oxidative stress, and immune cell phenotypes in peripheral blood were evaluated. Cortisol levels in the sera increased after the exhaustive endurance and resistance exercises and such increments were maintained through the recovery. Intra-cellular ROS levels also increased after the exhaustive endurance and resistance exercises. The ratio of CD4+ T cells to CD8+ T cells after each type of submaximal exercise decreased compared with that at the resting stage, and returned to the resting level at 30 min after the exercise. In this study, an exhaustive endurance or a resistance exercise with submaximal intensity caused excessive physical stress, intra-cellular oxidative stress, and post-exercise immunosuppression. This result suggests that excessive physical stress induced temporary immune dysfunction via physical and oxidative stress.
Assessing the Effect of Visualizations on Bayesian Reasoning through Crowdsourcing

People have difficulty understanding statistical information and are unaware of their wrong judgments, particularly in Bayesian reasoning. Psychology studies suggest that the way Bayesian problems are represented can impact comprehension, but few visual designs have been evaluated and only populations with a specific background have been involved. In this study, a textual and six visual representations for three classic problems were compared using a diverse subject pool through crowdsourcing. Visualizations included area-proportional Euler diagrams, glyph representations, and hybrid diagrams combining both. Our study failed to replicate previous findings in that subjects' accuracy was remarkably lower and visualizations exhibited no measurable benefit. A second experiment confirmed that simply adding a visualization to a textual Bayesian problem is of little help, even when the text refers to the visualization, but suggests that visualizations are more effective when the text is given without numerical values. We discuss our findings and the need for more such experiments to be carried out on heterogeneous populations of non-experts.
