A valid procedure for obtaining self-report of affect in marital interaction.

Thirty married couples interacted in a low-conflict situation and a high-conflict situation during which continuous physiological measures were obtained. Each spouse returned separately for a second session in which they watched the videotape of the interaction and provided a continuous self-report rating of their own affect while the same physiological measures were again obtained. Observers coded the spouses' affect during each speech unit. The self-reports of affect (a) discriminated the high-conflict interaction from the low-conflict interaction, (b) correlated significantly with marital satisfaction, (c) were coherent between husband and wife, and (d) were significantly related to the observers' coding of the couples' affect. Physiological data obtained during the interaction session were significantly related (using time-series analyses) to physiological data obtained during the recall session. In all comprehensive discussions of emotion the subject's own experience of affect has been considered an important channel of information (see Strongman, 1978). This channel has always been troublesome from an empirical standpoint in terms of meeting psychometric criteria of reliability and validity. One important application of a valid selfreport procedure would be in the study of emotion during social interaction. Ekman, Friesen, and Ellsworth (1972) noted that the study of emotion in the context of social interaction can make a number of unique contributions. One of these contributions is the study of interaction as it unfolds in time, which permits the analysis of the sequential nature of the interaction using time-series analysis. Thus, a method for procuring the self-report of affect that could provide a continuous record over an interaction session would be extremely useful in the study of emotion in social interaction.
Biological pattern in hypertension by race, sex, body weight, and skin color.

A population-based epidemiologic study of 2,184 residents of Charleston County, South Carolina, with a high morbidity and death rate from arteriosclerotic and hypertensive cardiovascular disease showed high prevalence of hypertension among Negroes compared with the prevalence in Charleston whites or American Negroes. The relationships of sex and age with hypertension follow different patterns in Negroes and whites. In contrast to the white population, no correlation between obesity and hypertension was found in Negroes. A positive correlation was found between skin pigmentation and hypertension in Negroes. There was also a significant difference in prevalence of group B blood type between lighter- and darker-pigmented Negroes, the darker half having the same "B" prevalence as West African Negroes, and 50% higher prevalence than American Negroes.
Impact of student choice of content adoption delay on course outcomes

It is difficult for a student to succeed in a course without access to course materials and assignments; and yet, some students delay up to a month in obtaining access to these essential materials. Students delay buying material required for their course due to multiple reasons. Out of a concern for students with limited financial resources, some publishers offer a period of free courtesy access. But this may lead to students having access later in the course but then having a lapsed period until they pay for the materials after the courtesy access period ends. Not having key course materials early on probably hurts learning, but how much? In this paper, we investigate the question, "Does lack of access to instructional material impact student performance in blended learning courses? " Specifically, we analyze students who purchased and obtained access to online content at different points in the course. We determine that both types of failure to obtain access to course materials (delaying in signing up for the product, or signing up for a free trial and letting the trial period lapse without purchasing the materials) are associated with substantially worse student outcomes. Students who purchased the product within the first few days of class had the best scores (median 77). Those who waited two weeks before accessing the product did the worst (median 56, effect size Cliff's Delta=0.31 1). We conclude with a discussion of possible interventions and actions that can be taken to ameliorate the situation.
Differentiation of hereditary spastic paraparesis from primary lateral sclerosis in sporadic adult-onset upper motor neuron syndromes.

OBJECTIVE To study whether clinical characteristics can differentiate sporadic presentations of hereditary spastic paraparesis (HSP) from primary lateral sclerosis (PLS). Differentiation between these diseases is important for genetic counseling and prognostication. DESIGN Case series. SETTING Tertiary referral center. PATIENTS One hundred four Dutch patients with an adult-onset, sporadic upper motor neuron syndrome of at least 3 years' duration. Hereditary spastic paraparesis was genetically confirmed in 14 patients (7 with SPG4 and 7 with SPG7 mutations). RESULTS All 14 patients with the SPG4 or SPG7 mutation had symptom onset in the legs, and 1 of the patients with the SPG7 mutation also developed symptoms in the arms. Of the other 90 patients, 78 (87%) had symptom onset in the legs. Thirty-six patients developed a PLS phenotype (bulbar region involvement), 15 had a phenotype that was difficult to classify as similar to HSP or PLS (involvement of legs and arms only), and 39 continued to have a phenotype similar to typical HSP (involvement of the legs only). Median age at onset was lower in patients with the SPG4 or SPG7 mutation (39 [range, 29-69] years), but there was considerable overlap with patients with the PLS phenotype (52 [range, 32-76] years). No differences were found in the features used by previous studies to distinguish HSP from PLS, including evidence of mild dorsal column impairment (decreased vibratory sense or abnormal leg somatosensory evoked potentials), symptoms of urinary urgency, or mild electromyographic abnormalities. CONCLUSIONS In most patients with a sporadic adult-onset upper motor neuron syndrome, differentiation of sporadic presentations of HSP from PLS based on clinical characteristics is unreliable and therefore depends on results of genetic testing.
A comparative study of different imaging modalities for successful percutaneous left atrial appendage closure

Objectives Accurate sizing of the left atrial appendage (LAA) is essential when performing percutaneous LAA closure. This study aimed to compare different LAA imaging modalities and sizing methods in order to obtain successful LAA closure. Background Percutaneous LAA closure is an increasingly used treatment strategy to prevent stroke in patients with atrial fibrillation. LAA sizing has typically been done by 2D-transoesophageal echocardiography (TEE). Methods Patients who had a preprocedural TEE and preprocedural and postprocedural multislice CT (MSCT) were identified. Preprocedural measurements of LAA ostia and landing zones by 2D-TEE, MSCT and angiography were collected and analysed for those patients with successful LAA closure - i.e. with no contrast leakage at 3-month follow-up MSCT. Results The study population (n=67) had a mean CHA2DS2-VASc score of 3.0 and HAS-BLED score of 2.7. Fifty-eight patients (87%) were identified to have successful LAA closure. Based on MSCT, 48 LAA sizings (83%) resulted in a correct LAA closure device size selection, whereas with 2D-TEE sizing, only 33 measurements (57%) would have resulted in a correct device size selection (p<0.01). Using adapted Bland-Altman method, MSCT-based perimeter-derived mean diameter was shown to be the best parameter to guide LAA device size selection for â€˜closed-endâ€™ devices (Amulet, WatchmanFLX), whereas the maximal diameter was the best parameter for the â€˜open-endâ€™ Watchman device. Conclusions Preprocedural MSCT-based LAA closure device size selection proves to be a more accurate method than conventional 2D-TEE-based sizing. Depending on the LAA closure device design, perimeter-derived mean diameter or maximal diameter could be the better sizing method.
Volumetric x-ray coherent scatter imaging of cancer in resected breast tissue: a Monte Carlo study using virtual anthropomorphic phantoms

Breast cancer patients undergoing surgery often choose to have a breast conserving surgery (BCS) instead of mastectomy for removal of only the breast tumor. If post-surgical analysis such as histological assessment of the resected tumor reveals insufficient healthy tissue margins around the cancerous tumor, the patient must undergo another surgery to remove the missed tumor tissue. Such re-excisions are reported to occur in 20%–70% of BCS patients. A real-time surgical margin assessment technique that is fast and consistently accurate could greatly reduce the number of re-excisions performed in BCS. We describe here a tumor margin assessment method based on x-ray coherent scatter computed tomography (CSCT) imaging and demonstrate its utility in surgical margin assessment using Monte Carlo simulations. A CSCT system was simulated in Geant4 and used to simulate two virtual anthropomorphic CSCT scans of phantoms resembling surgically resected tissue. The resulting images were volume-rendered and found to distinguish cancerous tumors embedded in complex distributions of adipose and fibroglandular breast tissue (as is expected in the breast). The images exhibited sufficient spatial and spectral (i.e. momentum transfer) resolution to classify the tissue in any given voxel as healthy or cancerous. ROC analysis of the classification accuracy revealed an area under the curve of up to 0.97. These results indicate that coherent scatter imaging is promising as a possible fast and accurate surgical margin assessment technique.
Positional cloning of a quantitative trait locus contributing to pain sensitivity: possible mediation by Tyrp1

To identify novel pain‐relevant genes, a set of 35 recombinant congenic strains derived from the sensitive C57BL/6 and resistant A/J strains were tested for their sensitivity to noxious heat on the radiant heat paw‐withdrawal test. Nine strains were found to display differential sensitivity, and the two most extreme responders were used to generate independent secondary crosses for quantitative trait locus (QTL) mapping. From these genetic analyses, a QTL, which we call Tpnr5, was mapped to a 14‐Mb interval of mouse chromosome 4 containing 39 genes. In addition to the paw‐withdrawal test phenotype, Tpnr5 may be relevant to mechanical and inflammatory nociception. A series of strategies – including in silico analyses, reverse transcriptase polymerase chain reaction (RT‐PCR) in multiple tissues and exonic DNA sequencing – were used to generate a list of six prioritized candidate genes. One of these, tyrosinase‐related protein 1 (Tyrp1), displayed enriched expression in the dorsal root ganglia, an inactivating (C110Y) mutation in the resistant A/J strain, and a null mutant found to be more resistant to thermal nociception compared to its wild‐type counterpart. Although other genes cannot be definitively ruled out, existing data are supportive of the candidacy of Tyrp1 as representing the Tpnr5 QTL. Tyrosinase‐related protein 1 is the rate‐limiting enzyme in the production of eumelanin, and possible relationships between eumelanin‐expressing cells and thermal nociception are discussed. The positional cloning of Tpnr5 is also considered in light of the heuristic value but continuing challenges of QTL mapping in the mouse.
Systematic Credit Risk and Pricing for Fixed Income Instruments

This article analyzes the sensitivity to systematic credit risk and pricing in fixed income instruments and compares corporate bonds and asset securitizations. The article finds cross-sectional variation of systematic credit risk given the same credit rating and a market premium for the systematic risk embedded in yield spreads. Therefore, credit ratings do not provide comprehensive information on the degree of systematic risk, and investors are compensated for such differences in systematic risk after controlling for credit ratings and other risk characteristics.
Mitigation of Interruption Reimbursements by Periodic Network Reconfiguration: Risk-Based Versus Expected-Value Optimization

The reimbursement for violation of customer quality standards such as maximal interruption frequency and duration is at the basis of modern quality of service regulation. In order to satisfy quality standards, distribution operators periodically reconfigure the network so as to minimize the risk of reimbursement. Reconfiguration relies upon reliability analysis of an "average year" and usually neglects the risk induced by failure variance. This is because the assessment of risk represents a considerable burden for real-scale systems. In this paper, we study the decision error induced by analyzing "average years" and investigate the evolution of this error with the periodicity of reconfiguration. Examples are given for illustrating the main results

Overweight among children decreased, but obesity prevalence remained high among women in South Africa, 1999–2005

Abstract Objective The aim of the present study was to assess anthropometric status in South African children and women in 2005 in order to document temporal trends in selected anthropometric parameters. Design Heights and weights were measured in a cross-sectional study of children aged 1–9 years and women aged 16–35 years. The WHO reference values and BMI cut-off points were used to determine weight status. Setting South Africa, representative sample based on census data. Subjects Children (n 2157) and women (n 2403). Results Stunting was the most common nutritional disorder affecting 21·7 % of children in 1999 and 20·7 % in 2005. The difference was not statistically significant. Underweight prevalence remained unchanged, affecting 8·1 % of children, whereas wasting affected 5·8 % of children nationally, a significant increase from 4·3 % of children in 1999. Rural children were most severely affected. According to the international BMI cut-off points for overweight and obesity, 10 % of children nationally were classified as overweight and 4 % as obese. The national prevalence of overweight and obesity combined for women was 51·5 %. The prevalence of overweight in children based on weight-for-height Z-score did not change significantly (8·0 % to 6·8 %, P = 0·138), but the combined overweight/obesity prevalence based on BMI cut-off points (17·1 % to 14·0 %, P = 0·02) decreased significantly from 1999 to 2005. Conclusions The double burden of undernutrition in children and overweight among women is evident in South Africa and getting worse due to increased childhood wasting combined with a high prevalence of obesity among urban women, indicating a need for urgent intervention.
Type 1 diabetes in India: Overall insights

Type 1 diabetes mellitus (T1DM) is also on increase like type 2 diabetes, even though not in the same proportion, but still with a trend of 3–5% increase/year. India has three new cases of T1DM/100,000 children of 0–14 years. Three sets of prevalence data shows 17.93 cases/100,000 children in Karnataka, 3.2 cases/100,000 children in Chennai, and 10.2 cases/100,000 children in Karnal (Haryana). T1DM may be autoimmune or idiopathic in nature and is present in 9% cases of insulin deficiency. T1DM is primarily caused by genetic factors, environmental factors, and disorder of the immune regulatory mechanism. A combination of all these three factors causes autoimmune disease, which may ultimately result in the destruction of pancreatic beta cells leading to hyperglycemia, ketoacidosis and potentially death, if not treated with insulin. Prediabetes is the phase before the onset of T1DM, which provides a window of opportunity for early intervention. All available interventions including steroids, immunosuppressants, and cyclosporins can be possibly applied during the prediabetes phase. The treatment goals for T1DM are simple and include maintaining near normal blood glucose levels and avoiding long-term complications, which is a constant juggle between insulin and maintaining an appropriate lifestyle. The Indian Council of Medical Research funded Registry of People with diabetes in India with young age at onset (YDR) was started in the year 2006 with 10 collaborating centres across India. This registry is focusing on to provide an overview of diabetes in the young.
Prediction of postoperative morbidity, mortality and rehabilitation in hip fracture patients: the cumulated ambulation score

Objective: To validate the cumulated ambulation score as an early postoperative predictor of short-term outcome in hip fracture patients. Design: Prospective, descriptive study. Setting: An orthopaedic hip fracture unit in a university hospital. Patients: Four hundred and twenty-six consecutive hip fracture patients with an independent walking function admitted from their own home. Rehabilitation followed a well-defined multimodal rehabilitation regimen and discharge criteria. Main outcome measure: Admission tests with a new mobility score to assess prefracture functional mobility and a short mental score for cognitive dysfunction were performed. On the first three postoperative days patients were assessed with the cumulated ambulation score consisting of a cumulated assessment of simple ambulation characteristics with a score from 0 to18 (fully mobile). The three assessments were correlated to short-term outcome parameters. Results: The cumulated ambulation score was a highly significant predictor for length of hospitalization, time to discharge status, 30-day mortality and postoperative medical complications (P < 0.001 for all). The cumulated ambulation score was superior in its association with all postoperative outcome parameters to both the New Mobility Score and the mental score. A cumulated ambulation score of ±10 correlated with a 99% survival at one month and 93% discharge to own home. Conclusion: The cumulated ambulation score is a potentially valuable score for early prediction of short-term postoperative outcome after hip fracture surgery.
Hotspot slicer: Slicing virtualized home Wi-Fi networks for air-time guarantee and traffic isolation

Nowadays, the usage of multiple virtual wireless networks on top of one physical AP is very common in home Wi-Fi networks. Be it Hotspots of Internet Service Providers (ISPs) or Mobile Network Operators (MNOs) used for offloading their traffic, community networks or plain so-called "Guest-Networks". Whereas the home user (AP owner) in the best case should not even be aware that his network connection is shared. Most of the ISPs and MNOs are now trying to convince their customers to install an additional virtual wireless hotspot network on their home AP and offer them in return the free usage of all other available hotspots. But, currently most costumers are skeptical as the providers cannot guarantee a downlink slice of air-time or real separation in time on the wireless access network. In this paper we demonstrate by using a novel downlink slicing scheme applied on commercial off-the-shelf hardware, how slicing on MAC level can be applied to truly guarantee a fixed amount of air-time for the home user and provide complete traffic separation in time between the home and the hotspot network. Moreover, our demonstrator shows the benefits of the approach by comparing the quality of a high definition video stream with and without our MAC slicing approach.
An Efficient Semianalytic Computation Method of Magnetic Field for a Circular Coil With Rectangular Cross Section

A semianalytic formula for calculating the magnetic field produced by a circular coil with rectangular cross section in air is proposed. In the formula, the coil is approximated as a series of circular rings with small cross sectional area, of which the current density can be considered as constant. In order to simplify the calculation of the magnetic field, the translation transformation and scaling transformation are introduced. Furthermore, all the possible singular cases, in the expressions, are treated properly. Therefore, with the help of one-dimensional Gauss-Legendre quadrature, the magnetic field at any points in space produced by current-carrying circular coil, especially inside the coil, can be calculated very easily.
Control of single phase grid connected multilevel inverter using model predictive control

This paper presents a single phase seven-level inverter grid connected photovoltaic (PV) system application. The proposed system consists of a PV arrays, a single phase seven-level inverter interface and single phase power grid. The control of the inverter is based on a model predictive control algorithm where the main aim is to control the injected power which is produced by the PV source, to improve the quality of the current waveform, to reduce the THD of the current and to ensure the elimination of the shift phase between the injected current and the grid voltage in order to fulfill the requirement of the smart grid network. To clarify the advantages of the application of the model predictive control to the proposed topology, simulation results using MATLAB/SIMULINK and real time simulations using dSPACE 1103 are provided in this paper.
A Novel Quad-Band Diversity Antenna for LTE and Wi-Fi Applications With High Isolation

A novel quad-band diversity antenna is presented with two radiating elements suitable for long-term evolution (LTE) and wireless fidelity (Wi-Fi) applications in handheld devices. The radiating elements are two planar inverted F-shaped antennas (PIFA) constructed by a meandered line and folded patch with interdigitated capacitive strips connected to the folded patch. To achieve high isolation between the two radiating elements, a defected ground plane (a combination of rectangular slot ring and inverted T-shaped slot stub) is employed. The antenna is designed to operate in the 746-787 MHz, 1850-1990 MHz, 1920-2170 MHz, and 3600-3700 MHz frequency bands. The characterization of the antenna in free-space as well as in the proximity of the user head and hand is presented. The results confirm the excellent performance of the proposed diversity antenna.
