Comparison of Matrix Pencil Extracted Features in Time Domain and in Frequency Domain for Radar Target Classification

Feature extraction is a challenging problem in radar target identification. In this paper, we propose a new approach of feature extraction by using Matrix Pencil Method in Frequency Domain (MPMFD). The proposed method takes into account not only the magnitude of the signal, but also its phase, so that all the physical characteristics of the target will be considered. With this method, the separation between the early time and the late time is not necessary. The proposed method is compared to Matrix Pencil Method in Time Domain (MPMTD). The methods are applied on UWB backscattered signal from three canonical targets (thin wire, sphere, and cylinder). MPMFD is applied on a complex field (real and imaginary parts of the signal). To the best of our knowledge, this comparison and the reconstruction of the complex electromagnetic field by MPMFD have not been done before. We show the effect of the two extraction methods on the accuracy of three different classifiers: Naive bayes (NB), K-Nearest Neighbor (K-NN), and Support Vector Machine (SVM). The results show that the accuracy of classification is better when using extracted features by MPMFD with SVM.
Exploring Shopper’s Browsing Behavior and Attention Level with an EEG Biosensor Cap

The online shopping market is developing rapidly, meaning that it is important for retailers and manufacturers to understand how consumers behave online compared to when in brick-and-mortar stores. Retailers want consumers to spend time shopping, browsing, and searching for products in the hope a purchase is made. On the other hand, consumers may want to restrict their duration of stay on websites due to perceived risk of loss of time or convenience. This phenomenon underlies the need to reduce the duration of consumer stay (namely, time pressure) on websites. In this paper, the browsing behavior and attention span of shoppers engaging in online shopping under time pressure were investigated. The attention and meditation level are measured by an electroencephalogram (EEG) biosensor cap. The results indicated that when under time pressure shoppers engaging in online shopping are less attentive. Thus, marketers may need to find strategies to increase a shopper’s attention. Shoppers unfamiliar with product catalogs on shopping websites are less attentive, therefore marketers should adopt an interesting style for product catalogs to hold a shopper’s attention. We discuss our findings and outline their business implications.
Negative regulators of STAT3 signaling pathway in cancers

: STAT3 is the most ubiquitous member of the STAT family and involved in many biological processes, such as cell proliferation, differentiation, and apoptosis. Mounting evidence has revealed that STAT3 is aberrantly activated in many malignant tumors and plays a critical role in cancer progression. STAT3 is usually regarded as an effective molecular target for cancer treatment, and abolishing the STAT3 activity may diminish tumor growth and metastasis. Recent studies have shown that negative regulators of STAT3 signaling such as PIAS, SOCS, and PTP, can effectively retard tumor progression. However, PIAS, SOCS, and PTP have also been reported to correlate with tumor malig-nancy, and their biological function in tumorigenesis and antitumor therapy are somewhat controversial. In this review, we summarize actual knowledge on the negative regulators of STAT3 in tumors, and focus on the potential role of PIAS, SOCS, and PTP in cancer treatment. Furthermore, we also outline the STAT3 inhibitors that have entered clinical trials. Targeting STAT3 seems to be a promising strategy in cancer therapy. eight members are characterized by their N-terminal region with variable length and limited homology, an extended SH2 domain (ESS), a central SH2 domain and a conserved SOCS box at the C-terminus.
Prevalence of depression and anxiety in women newly diagnosed with vulvovaginal atrophy and dyspareunia.

OBJECTIVE To quantify the association between vulvovaginal atrophy and depression, major depressive disorder, and anxiety. METHODS Women with vulvovaginal atrophy from the Truven Health MarketScan Commercial and Medicare Supplemental Databases (01/2010-09/2016) with ≥365 days of continuous insurance coverage before and after the first vulvovaginal atrophy/dyspareunia diagnosis (index date) were selected. Women with vulvovaginal atrophy were matched 1:3 to women without (controls) according to age, calendar year, health plan, and region. The study period spanned from 12 months before to 12 months after index date. The ratios of diagnosed depression, major depressive disorder, and anxiety among women with vulvovaginal atrophy and the controls were calculated. Logistic regressions adjusting for proxies of menopause were used to compare prevalence. RESULTS In all, 125,889 women with vulvovaginal atrophy and 376,057 controls were included (mean age 60.7 [45-101]). The prevalence of depression, major depressive disorder, and anxiety was higher among women with vulvovaginal atrophy compared with controls (23.9% vs 18.9%, 6.3% vs 4.7%, 16.6% vs 11.3%), with prevalence ratios of 1.26, 1.33, and 1.47, respectively (all P < 0.0001). Highest prevalences and differences were observed in younger women. Findings were consistent when analyzing newly diagnosed conditions. When adjusting for proxies of menopause (insomnia, vasomotor symptoms, dysuria, and estrogen therapy), vulvovaginal atrophy remained significant (prevalence odds ratios; depression 1.23, major depressive disorder 1.22, anxiety 1.39; all P < 0.0001). CONCLUSIONS Vulvovaginal atrophy is associated with a significantly higher prevalence/incidence of depression, major depressive disorder, and anxiety. The higher prevalence/incidence and greater differences in younger women highlight the need for a multidisciplinary approach and early diagnosis/management of vulvovaginal atrophy.
The Practical Effects of Measurement Invariance: Gender Invariance in Two Big Five Personality Measures

The essence of measurement invariance (MI) analysis is to test the assumption that observed scores on a scale accurately reflect respondents’ standings on a measured construct. Based on exploratory structural equation modeling, the current study examines gender-based MI in two Big Five measures of personality: the Mini-IPIP, and the Big Five Inventory (BFI) facet scales. We report results for MI based on both model fit indices and a practical significance index that quantifies the extent of noninvariance (i.e., dMACS). From the latter, we partition the observed group mean differences in scale scores into construct-irrelevant group differences versus construct-relevant group differences. In measures of Agreeableness, Conscientiousness, Extraversion, and Neuroticism across instruments, results supported metric invariance but not scalar invariance. That said, findings of statistical noninvariance were generally small in terms of practical effects, although some notable variability in the effects was evident. Overall, the current results provide evidence regarding gender-based MI of Big Five personality measures that are more detailed than that provided in past work. More generally, this study also provides useful guidance for future researchers investigating both the statistical and practical significance of measurement invariance.

PVDF-PZT Composite Films for Strain Sensing Applications

Piezoelectric polymer-ceramic composites are promising materials for transducer applications. PVDF-PZT composite films with 50% weight fraction of PZT have been developed using solvent cast method. Films are investigated using X-ray diffraction technique, Scanning Electron Microscopy, and Differential Scanning Calorimetry to study crystal structural changes, distribution of particles within the polymer matrix, the changes induced in the melting transition and in the degree of crystallinity of the composites, respectively. The composite films are tested as strain sensor and are compared with conventional strain gauges fixed on CFRP specimens. A Load in steps of 1kN was applied at the rate of 0.5mm/min. It was found that the strain variation was linear to the voltage output from composite PVDF compare to strain values.
Interactive comment on “ Effects of seawater < i > p < / i > CO < sub > 2 < / sub > changes on the calcifying fluid of scleractinian corals ” by S . Hohn and A .

The authors present a model of coral calcification that aims to simulate how coral calcification responds to rising CO2. The model computes the kinetic reactions of carbonate chemistry and the flux of ions in and between four different model compartments: the seawater, the coral tissue, the coelenteron and the calcifying fluid. A model such as this is potentially very valuable as it attempts to provide a physiological, mechanistic explanation to why corals calcify more slowly under ocean acidification. As the authors point out, corals exert significant biological control over physio-chemical conditions at the site of calcification, so why changes in seawater chemistry (the growth medium) should effect the calcifying fluid remains an important question in ocean acidification research. The authors have constructed their model in such a way that it reproduces measurements of Ca2+ and pH in the calcifying fluid made by microelectrodes under seawater conditions of pH8.2 (Al-Horani et al. 2003. Mar Biol). The microelectrode data of Al-Horani is the only set of continuous light-dark data currently available that provides the kinetics necessary with which to test the model. Whether one agrees with the set up of model or not, it integrates a certain amount of what is known about the physiology underlying coral calcification and provides a useful platform with which to generate and investigate hypotheses about the mechanisms underpinning coral calcification. Although the overall ideas and approach underlying the model potentially make it a valuable contribution to the literature, there are some issues related to fundamental physiology that could be be addressed/ improved. The biggest concern relates to the values of tissue pH which are currently way above the range of physiological norms for any animal, including coral. I discuss this issue further in specific comments. Other issues relate to confusing terminology and underrepresentation of the literature, which are also discussed in my specific comments. I hope these issues can be addressed in a revised paper.
Modal Testing of the TX-100 Wind Turbine Blade

This test report covers the SNL modal test results for two nominally identical TX-100 wind turbine blades. The TX-100 blade design is unique in that it features a passive braking, force-shedding mechanism where bending and torsion are coupled to produce desirable aerodynamic characteristics. A specific aim of this test is to characterize the coupling between bending and torsional dynamics. The results of the modal tests and the subsequent analysis characterize the natural frequencies, damping, and mode shapes of the individual blades. The results of this report are expected to be used for model validation--the frequencies and mode shapes from the experimental analysis can be compared with those of a finite-element analysis. Damping values are included in the results of these tests to potentially improve the fidelity of numerical simulations, although numerical finite element models typically have no means of predicting structural damping characteristics. Thereafter, an additional objective of the test is achieved in evaluating the test to test and unit variation in the modal parameters of the two blades.
Prediction of Compressive Strength of Concrete Using Artificial Neural Network and Genetic Programming

An effort has been made to develop concrete compressive strength prediction models with the help of two emerging data mining techniques, namely, Artificial Neural Networks (ANNs) and Genetic Programming (GP). The data for analysis and model development was collected at 28-, 56-, and 91-day curing periods through experiments conducted in the laboratory under standard controlled conditions. The developed models have also been tested on in situ concrete data taken from literature. A comparison of the prediction results obtained using both the models is presented and it can be inferred that the ANN model with the training function Levenberg-Marquardt (LM) for the prediction of concrete compressive strength is the best prediction tool.
Brief culturally informed smartphone interventions decrease breast cancer symptom burden among Latina breast cancer survivors

Latina breast cancer survivors (BCS) report more symptom burden and poorer health‐related quality of life than non‐Latina BCS. However, there are few evidence‐based and culturally informed resources that are easily accessible to this population. This study aimed to establish the feasibility and preliminary efficacy of the My Guide and My Health smartphone applications among Latina BCS. Both applications are culturally informed and contain evidence‐based information for reducing symptom burden and improving health‐related quality of life (My Guide) or healthy lifestyle promotion (My Health).
Micromagnetic simulations of magnetostatically coupled Nickel nanowires

Magnetic structures and magnetization processes in arrays of closely packed Ni nanowires (length l=1 μm, diameter d=40 nm, and period: 100 nm) are investigated by means of micromagnetic modelling. The simulations are performed with an algorithm based on the finite element method combined with the boundary element method which allows for the accurate calculation of magnetostatic interactions. Magnetization states of Ni nanowires at zero field are calculated. Only few, simple magnetization configurations result to be stable. Transient states of the magnetization indicate that magnetization reversal occurs by means of nucleation at the ends of the particles and subsequent soliton propagation. Hysteresis loops of up to 16 interacting nanowires are simulated. It turns out that magnetostatic interactions between the wires have a significant influence on the switching field.
Springtime microwave emissivity changes in the southern Kara Sea

Springtime microwave brightness temperatures over first-year ice are examined for the southern Kara Sea. Snow emissivity changes are revealed by episodic drops in the 37- to 18-GHz brightness temperature gradient ratio measured by the Nimbus 7 scanning multichannel microwave radiometer. We suggest that the negative gradient ratios in spring 1982 result from increased scatter at 37 GHz due to the formation of a near-surface hoar layer. This interpretation is supported by the results of a surface radiation balance model that shows the melt signature occurring at below freezing temperatures but under clear-sky conditions with increased solar input to the surface. Published observations from the Greenland ice cap show a surface hoar layer forming under similar atmospheric conditions owing to the increased penetration and absorption of solar radiation just below the surface layer. In spring/early summer 1984 similar gradient ratio signatures occur. They appear to be due to several days of freeze-thaw cycling following the movement of a low-pressure system through the region. These changes in surface emissivity represent the transition from winter to summer conditions (as defined by the microwave response) and are shown to be regional in extent and to vary with the synoptic circulations.
Familial Creutzfeldt–Jakob Disease with a PRNP Mutation at Codon 180 Presented with Visual Hallucinations and Illusions

Creutzfeldt-Jakob disease (CJD) is a fatal neurodegenerative disease characterized by rapidly progressive dementia, cerebellar ataxia, myoclonus, parkinsonism, or various neurobehavioral symptoms due to tissue deposition of a misfolded prion protein.1 A genetic variant in the prion protein gene (PRNP) is the most common cause of familial CJD (fCJD) which accounts for only 10%–15% of all CJD patients.2,3 We report a rare case with a nucleotide substitution of an isoleucine for a valine at codon 180 (V180I) in PRNP, who presented with visual hallucinations and illusions.
Features of immunoregulation in patients with pulmonary tuberculosis with blood eosinophilia

The aimof the investigation was to determine the characteristics of the immune response regulation for pulmonary tuberculosis (TB) and to analyze the role of regulatory T cells in the immunopathogenesis of TB with eosinophilia in the blood, depending on the clinical form of the disease and sensitivity of Micobacterium tuberculosis to anti-TB drugs.Materials and methods.157 patients who were initially diagnosed with infiltrative and disseminated TB were examined. The material of the study was venous blood and culture of mononuclear leukocytes isolated from venous blood. The content of interleukin (IL) 4, IL-10 and transforming factor beta (TGFβ) in culture suspensions of mononuclear leukocytes in vitro and IL-5 in the blood was determined by enzyme-linked immunosorbent assay (ELISA) test. The expression of surface molecules CD4, CD20, CD25 and intracellular transcription factor Foxp3 by lymphocytes of the blood was evaluated by flow cytometry. The obtained results were analyzed by statistical methods.Results. It is shown that excessive generation of regulatory T cells in patients with TB is associated with eosinophilia of the blood and imbalance of immune response regulation mechanisms. In TB with eosinophilia, an increase in the number of Foxp3-positive regulatory T cells in the blood is combined with in vitro hypersecretion of anti-inflammatory cytokines TGFβ, IL-10, IL-4 and an increase in the content of CD20+ B lymphocytes and IL-5 in the blood. These changes are most pronounced in the disseminated form of TB in combination with drug resistance.Conclusion. Characteristics of immunoregulation at TB with blood eosinophilia are associated with activation of immunosuppression mechanisms and polarization of immune response towards Th2-dependent pathway.
Early Infectious Disease Consultation Is Associated With Lower Mortality in Patients With Severe Sepsis or Septic Shock Who Complete the 3-Hour Sepsis Treatment Bundle

Abstract Objective Severe sepsis and septic shock (SS/SS) treatment bundles reduce mortality, and early infectious diseases (ID) consultation also improves patient outcomes. We retrospectively examined whether early ID consultation further improves outcomes in Emergency Department (ED) patients with SS/SS who complete the sepsis bundle. Method We included 248 adult ED patients with SS/SS who completed the 3-hour bundle. Patients with ID consultation within 12 hours of ED triage (n = 111; early ID) were compared with patients who received standard care (n = 137) for in-hospital mortality, 30-day readmission, length of hospital stay (LOS), and antibiotic management. A competing risk survival analysis model compared risks of in-hospital mortality and discharge alive between groups. Results In-hospital mortality was lower in the early ID group unadjusted (24.3% vs 38.0%, P = .02) and adjusted for covariates (odds ratio, 0.47; 95% confidence interval (CI), 0.25–0.89; P = . 02). There was no significant difference in 30-day readmission (22.6% vs 23.5%, P = .89) or median LOS (10.2 vs 12.1 days, P = .15) among patients who survived. A trend toward shorter time to antibiotic de-escalation in the early ID group (log-rank test P = .07) was observed. Early ID consultation was protective of in-hospital mortality (adjusted subdistribution hazard ratio (asHR), 0.60; 95% CI 0.36–1.00, P = . 0497) and predictive of discharge alive (asHR 1.58, 95% CI, 1.11–2.23; P-value .01) after adjustment. Conclusions Among patients receiving the SS/SS bundle, early ID consultation was associated with a 40% risk reduction for in-hospital mortality. The impact of team-based care and de-escalation on SS/SS outcomes warrants further study.
Association of HbA 1 c with Urinary ACR & eGFR in Type-2 Diabetes Mellitus

Background Diabetic nephropathy is a chronic micro vascular complication of poorly controlled diabetes mellitus (DM), leading to end stage renal disease (ESRD). Control of DM is monitored by HbA1c. There are two early markers to assess early renal impairment: Microalbuminuria (MA) & Glomerular Filtration Rate (GFR). Estimation of MA needs 24 hours collection of urine. GFR is clinically assessed by creatinine clearance rate (CCR) at the same time for accurate estimation of GFR which also needs 24 hours urine collection. Faulty timing and non compliance for 24 hours urine collection may give erroneous results. MA is better reflected by spot urine urinary albumin-creatinine ratio (ACR). Some formula based calculation of GFR, called estimated GFR (eGFR) are well correlated with CCR which needs only single blood sample for S.Creatinine (S.Cr). For example one such formula is Cockroft-Gault (C-G) formula. Objective To evaluate the association of HbA1c with urinary ACR and eGFR in Type 2DM. Design It was a cross sectional study carried out in the department of Biochemistry, Sylhet MAG Osmani Medical College, from July 2010 to June 2011. Methods Fifty (50) known type 2 DM patients of 40-60 years age were evaluated dividing them on the basis of HbA1c (<8%,>8%), duration of DM (>5 years, <5 years), normotensives or hypertensives. FBS, S.Cr, Urinary Albumin & Creatinine were estimated. eGFR and urinary ACR were calculated. Results were expressed as mean ± SD. Data were analyzed with SPSS software version (12.0). Unpaired ’t’ test and Pearson’s correlation tests were performed as tests of significance. Value of ‘p’<0.05 was the level of significance. Results Significant difference of S.Cr & HbA1c was found between study groups on HbA1c<8% and >8%. DBP was significantly raised in hypertensive type 2 DM. Duration of DM did not show significant correlation with renal functional parameters. Serum Creatinine & U.ACR had significant positive correlation with HbA1c>8% and only with ACR but not with S.Cr in study subjects having HbA1c<8%. 1.
