Singular Value Decomposition and Akaike Information Criterion Based through Wall Image Enhancement

Singular value decomposition and Akaike information criterion based image enhancement is proposed for through wall imaging. Akaike information criterion is used with singular value decomposition to find spectral images belonging to targets. Simulation results compared on the basis of mean square error, peak signal to noise ratio, miss detection, false detection and visual inspection show the significance of the proposed scheme.
Verifiable social data outsourcing

Social data outsourcing is an emerging paradigm for effective and efficient access to the social data. In such a system, a third-party Social Data Provider (SDP) purchases complete social datasets from Online Social Network (OSN) operators and then resells them to data consumers who can be any individuals or entities desiring the complete social data satisfying some criteria. The SDP cannot be fully trusted and may return wrong query results to data consumers by adding fake data and deleting/modifying true data in favor of the businesses willing to pay. In this paper, we initiate the study on verifiable social data outsourcing whereby a data consumer can verify the trustworthiness of the social data returned by the SDP. We propose three schemes for verifiable queries over outsourced social data. The three schemes all require the OSN provider to generate some cryptographic auxiliary information, based on which the SDP can construct a verification object for the data consumer to verify the query-result trustworthiness. They differ in how the auxiliary information is generated and how the verification object is constructed and verified. Extensive experiments based on a real Twitter dataset confirm the high efficacy and efficiency of our schemes.
Temporal Dynamics of European Bat Lyssavirus Type 1 and Survival of Myotis myotis Bats in Natural Colonies

Many emerging RNA viruses of public health concern have recently been detected in bats. However, the dynamics of these viruses in natural bat colonies is presently unknown. Consequently, prediction of the spread of these viruses and the establishment of appropriate control measures are hindered by a lack of information. To this aim, we collected epidemiological, virological and ecological data during a twelve-year longitudinal study in two colonies of insectivorous bats (Myotis myotis) located in Spain and infected by the most common bat lyssavirus found in Europe, the European bat lyssavirus subtype 1 (EBLV-1). This active survey demonstrates that cyclic lyssavirus infections occurred with periodic oscillations in the number of susceptible, immune and infected bats. Persistence of immunity for more than one year was detected in some individuals. These data were further used to feed models to analyze the temporal dynamics of EBLV-1 and the survival rate of bats. According to these models, the infection is characterized by a predicted low basic reproductive rate (R0 = 1.706) and a short infectious period (D = 5.1 days). In contrast to observations in most non-flying animals infected with rabies, the survival model shows no variation in mortality after EBLV-1 infection of M. myotis. These findings have considerable public health implications in terms of management of colonies where lyssavirus-positive bats have been recorded and confirm the potential risk of rabies transmission to humans. A greater understanding of the dynamics of lyssavirus in bat colonies also provides a model to study how bats contribute to the maintenance and transmission of other viruses of public health concern.
Applicant Reactions and Their Consequences: Review, Advice, and Recommendations for Future Research

Recent years have seen an abundance of research addressing applicant reactions to personnel recruitment and standard selection procedures. However, most of this research focuses on isolating the determinants of these reactions rather than on their consequences. For example, just because an individual perceives a selection procedure as unfair, does this actually have any impact on the organization? In an attempt to fill this void in the literature, the current paper focuses on the outcomes and consequences of applicant reactions to personnel selection procedures. Specifically, the current paper (1) reviews the extant research on the consequences of applicant reactions, (2) advances a summative model of existing theory and research, (3) provides recommendations to organizational leaders who are concerned about the impact of applicant reactions to their personnel selection procedures, and (4) discusses directions for future research that will better substantiate these recommendations given to organizational leaders.
Can children undergoing ophthalmologic examinations under anesthesia be safely anesthetized without using an IV line?

Purpose: To document that with proper patient and procedure selection, children undergoing general inhalational anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, peri-ocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis) can be safely anesthetized without the use of an intravenous (IV) line. Children are rarely anesthetized without IV access placement. We performed a retrospective study to determine our incidence of IV access placement during examinations under anesthesia (EUA) and the incidence of adverse events that required intraoperative IV access placement. Methods: Data collected from our operating room (OR) information system includes but is not limited to diagnosis, anesthesiologist, surgeon, and location of IV catheter (if applicable), patient’s date of birth, actual procedure, and anesthesia/procedure times. We reviewed the OR and anesthetic records of children (>1 month and <10 years) who underwent EUAs between January 1, 2003 and May 31, 2009. We determined the percentage of children who were anesthetized without IV access placement, as well as the incidence of any adverse events that required IV access placement, intraoperatively. Results: We analyzed data from 3196 procedures performed during a 77-month period. Patients’ ages ranged from 1 month to 9 years. Overall, 92% of procedures were performed without IV access placement. Procedure duration ranged from 1–39 minutes. Reasons for IV access placement included parental preference for antinausea medication and/or attending preference for IV access placement. No child who underwent anesthesia without an IV line had an intraoperative adverse event requiring insertion of an IV line. Conclusion: Our data suggest that for children undergoing general anesthesia for ophthalmologic exams (with or without photos, ultrasound, laser treatment, intraocular injection of chemotherapy, suture removal, and/or replacement of ocular prosthesis), anesthesia can be safely conducted without placement of an IV line.
Community Polarization Over Educational Programs Can Be Avoided.

The series of events involved in implementing an innovative educational project in a fairly conservative community are outlined with particular reference to parental dissemination procedures, the role of the media, and staff response strategies. Shortly after the project's inception, two challenges against the use of an affective curriculum were mounted by a couple of opposition parents. The attempts were considered unsuccessful and several operating assumptions for new programs were described.
A Resource Allocation Protocol for Providing Quality of Service in Grid Computing

The problem of allocating processes of a Grid application to compute servers can be formulated as a distributed search problem. The goal is to allocate an application’s processes to those compute servers that can provide the required Quality of Service and can execute the processes in a cost-efficient way. We present a protocol to identify compute servers that can execute the application with minimal cost and provide the required Quality of Service for the application. Relying on a heuristic search algorithm, the protocol makes use of statistical data of the compute servers' efficiency in past process executions.
A comparison of bridging fault simulation methods

This study provides bridging fault simulation data obtained from the AMD-K6 microprocessor. It shows that: (1) high stuck-at fault coverage (99.5%) implies high bridging fault coverage; (2) coverage of a bridging fault by both wired-AND and wired-OR behavior does not guarantee detection of that fault when compared against a more accurate (transistor-level simulation) modeling method. A set of netname pairs representing bridging fault sites were extracted from layout and used for each fault modeling method. Results show that pattern generation should be driven by the most accurate modeling method when pursuing 100% bridging coverage, since less accurate methods will not necessarily converge to a high quality result.
Reduced work of breathing after single lung transplantation for emphysema.

BACKGROUND Pulmonary emphysema, with or without chronic bronchitis, has emerged as the most common indication for successful single lung transplantation. Although gas exchange can be expected to improve after successful transplantation, such changes do not adequately explain the improvement in dyspnea experienced by these patients and resulting in improved quality of life. METHODS We prospectively studied the respiratory mechanics of 14 single lung transplantation recipients with pulmonary emphysema, of whom 10 have been followed up beyond 1 year. The mean age of the group was 48.8 years (range, 42 to 60 years) for the seven men and seven women. Average donor-predicted total lung capacity was 0.6 L (+0.2 [standard error]) greater than recipient-predicted total lung capacity. Comparison of pulmonary resistance, dynamic lung compliance, and static lung compliance were taken to examine the possible role of reduced airways resistance and of improved elastic recoil in the reduced work of breathing. Results were analyzed by means of a one-tailed paired Student t test and linear regression analysis (both stepwise and multivariate); results are tabulated by mean (+/- 1 [standard error]). RESULTS Between preoperative measurements and 12 months postoperatively, maximum lung elastic recoil increased from 8.1 (+/- 0.7) to 11.3 (+/- 1.0) cm H2O, p < 0.01; pulmonary resistance fell from 8.3 (+/- 0.8) to 5.4 (+/- 0.7) cm H2O sec/L, p < 0.01. Dynamic lung compliance fell from 0.23 (+/- 0.04) to 0.12 (+/- 0.02) L/cm H2O, p < 0.02, and static lung compliance fell from 0.66 (+/- 0.13) to 0.22 (+/- 0.05) L/cm H2O, p < 0.001. CONCLUSIONS The decline in lung compliance after single lung transplantation reflects the importance of improvement in elastic recoil and reduced chest wall distention, improving the work of breathing. The 67% decline in static lung compliance (300% increase in elastic recoil) is probably the single most important mechanical factor leading to reduced dyspnea after single lung transplantation for emphysema.
Run-time fault detection in monitor based concurrent programming

The monitor concept provides a structured and flexible high-level programming construct to control concurrent accesses to shared resources. It has been widely used in concurrent programming environments for implicitly ensuring mutual exclusion and explicitly achieving process synchronization. This paper proposes an extension to the monitor construct for detecting run-time errors in monitor operations. Monitors are studied and classified according to their functional characteristics. A taxonomy of concurrency control faults over a monitor is then defined. The concepts of a monitor event sequence and a monitor state sequence provide a uniform approach to history information recording and fault detection. Rules for detecting various types of faults are defined. Based on these rules, fault detection algorithms are developed. A prototypical implementation of the proposed monitor construct with run-time fault detection mechanisms has been developed in Java. We briefly report our experience with and evaluation of our robust monitor prototype.
Thyroid Disease Associated With Exposure to the Nevada Nuclear Weapons Test Site Radiation: A Reevaluation Based on Corrected Dosimetry and Examination Data

Background: A study was begun in 1965 to 1966 to determine whether children exposed to radioactive iodine from nuclear weapons testing at the Nevada Test Site from 1951 through 1962 were at higher risk of thyroid disease. In 1993, we reported that among those examined in 1985 to 1986 (Phase II) there was an association between radiation from the Nevada Test Site and thyroid neoplasms. Methods: We reevaluated the relationship between exposure to Nevada Test Site fallout and thyroid disease using newly corrected dose estimates and disease outcomes from the Phase II study. A prospective cohort of school children 12 to 18 years old living in Utah, Nevada, and Arizona was first examined for thyroid disease in 1965 to 1966 and reexamined in 1985 to 1986. In the Phase II report, 2497 subjects formed the basis for this analysis. Thyroid disease, including thyroid neoplasms and thyroiditis, was expressed as cumulative incidence and risk ratios (RRs) with a dose–response expressed as excess risk ratio (ERR/Gy). Results: The RR between thyroid radiation dose in the highest dose group and thyroid neoplasms increased from 3.4 (in the earlier analysis) to 7.5. The RR for thyroiditis increased from 1.1 to 2.7 with an ERR/Gy of 4.9 (95% confidence interval = 2.0 to 10.0). There were too few malignant thyroid neoplasms to estimate risk. Conclusions: Persons exposed to radioactive iodine as children have an increased risk of thyroid neoplasms and autoimmune thyroiditis up to 30 years after exposure.
Reduction in viscoelasticity in cystic fibrosis sputum in vitro using combined treatment with Nacystelyn and rhDNase

The objective of this study was to evaluate the individual and combined effects of Nacystelyn (NAL) and rhDNase in vitro on the rheological properties of cystic fibrosis (CF) sputum. Sputum samples were collected from 11 CF patients and subjected to the following protocols: 1) negative control sample without any treatment; 2) positive control sample incubated with 0.02 ml of normal saline; 3) incubation of CF sputum with 0.02 mL DNase (25 μg/mL in normal saline) at 37°C to achieve 2.5 μg/g final sputum concentration (∼100 nM); 4) incubation of CF sputum with 0.02 mL NAL (30.9 μg/mL in normal saline) at 37°C to achieve 3.09 μg/g final sputum concentration (10 μM); and 5) combination of protocols 3 and 4 with half the concentration of each drug. The samples in protocols 2 through 5 were incubated for 30 minutes at 37°C. For each protocol, spinnability by filancemeter and viscoelasticity (log G*) by magnetic microrheometer were measured at baseline and 30 minutes.
Treatment for primary postpartum haemorrhage.

BACKGROUND Primary postpartum haemorrhage (PPH) is one of the top five causes of maternal mortality in both developed and developing countries. OBJECTIVES To assess the effectiveness and safety of any intervention used for the treatment of primary PPH. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 August 2013). SELECTION CRITERIA Randomised controlled trials comparing any interventions for the treatment of primary PPH. DATA COLLECTION AND ANALYSIS We assessed studies for eligibility and quality and extracted data independently. We contacted authors of the included studies to request more information. MAIN RESULTS Ten randomised clinical trials (RCTs) with a total of 4052 participants fulfilled our inclusion criteria and were included in this review.Four RCTs (1881 participants) compared misoprostol with placebo given in addition to conventional uterotonics. Adjunctive use of misoprostol (in the dose of 600 to 1000 mcg) with simultaneous administration of additional uterotonics did not provide additional benefit for our primary outcomes including maternal mortality (risk ratio (RR) 6.16, 95% confidence interval (CI) 0.75 to 50.85), serious maternal morbidity (RR 0.34, 95% CI 0.01 to 8.31), admission to intensive care (RR 0.79, 95% CI 0.30 to 2.11) or hysterectomy (RR 0.93, 95% CI 0.16 to 5.41). Two RCTs (1787 participants) compared 800 mcg sublingual misoprostol versus oxytocin infusion as primary PPH treatment; one trial included women who had received prophylactic uterotonics, and the other did not. Primary outcomes did not differ between the two groups, although women given sublingual misoprostol were more likely to have additional blood loss of at least 1000 mL (RR 2.65, 95% CI 1.04 to 6.75). Misoprostol was associated with a significant increase in vomiting and shivering.Two trials attempted to test the effectiveness of estrogen and tranexamic acid, respectively, but were too small for any meaningful comparisons of pre-specified outcomes.One study compared lower segment compression but was too small to assess impact on primary outcomes.We did not identify any trials evaluating surgical techniques or radiological interventions for women with primary PPH unresponsive to uterotonics and/or haemostatics. AUTHORS' CONCLUSIONS Clinical trials included in the current review were not adequately powered to assess impact on the primary outcome measures. Compared with misoprostol, oxytocin infusion is more effective and causes fewer side effects when used as first-line therapy for the treatment of primary PPH. When used after prophylactic uterotonics, misoprostol and oxytocin infusion worked similarly. The review suggests that among women who received oxytocin for the treatment of primary PPH, adjunctive use of misoprostol confers no added benefit.The role of tranexamic acid and compression methods requires further evaluation. Furthermore, future studies should focus on the best way to treat women who fail to respond to uterotonic therapy.
A Processing Method for Pitch Smoothing Based on Autocorrelation and Cepstral F0 Detection Approaches

Chinese is known as a syllabic and tonal language and tone recognition plays an important role and provides very strong discriminative information for Chinese speech recognition [1]. Usually, the tone classification is based on the F0 (fundamental frequency) contours [2]. It is possible to infer a speaker's gender, age and emotion from his/her pitch, regardless of what is said. Meanwhile, the same sequence of words can convey very different meanings with variations in intonation. However, accurate pitch detection is difficult partly because tracked pitch contours are not ideal smooth curves. In this paper, we present a new smoothing algorithm for detected pitch contours. The effectiveness of the proposed method was shown using the HUB4-NE [3] natural speech corpus.
Systems-Wide Analysis of Acclimation Responses to Long-Term Heat Stress and Recovery in the Photosynthetic Model Organism Chlamydomonas reinhardtii[W][OPEN]

Early acclimation responses of Chlamydomonas to long-term heat stress are directed toward restoration of protein homeostasis and membrane fluidity involving the redirection of photosynthetic electron flow from carbon fixation to saturated fatty acid synthesis, while late responses deal with the depletion of electron sinks. During recovery, cells aim at a rapid resumption of cell division/growth. We applied a top-down systems biology approach to understand how Chlamydomonas reinhardtii acclimates to long-term heat stress (HS) and recovers from it. For this, we shifted cells from 25 to 42°C for 24 h and back to 25°C for ≥8 h and monitored abundances of 1856 proteins/protein groups, 99 polar and 185 lipophilic metabolites, and cytological and photosynthesis parameters. Our data indicate that acclimation of Chlamydomonas to long-term HS consists of a temporally ordered, orchestrated implementation of response elements at various system levels. These comprise (1) cell cycle arrest; (2) catabolism of larger molecules to generate compounds with roles in stress protection; (3) accumulation of molecular chaperones to restore protein homeostasis together with compatible solutes; (4) redirection of photosynthetic energy and reducing power from the Calvin cycle to the de novo synthesis of saturated fatty acids to replace polyunsaturated ones in membrane lipids, which are deposited in lipid bodies; and (5) when sinks for photosynthetic energy and reducing power are depleted, resumption of Calvin cycle activity associated with increased photorespiration, accumulation of reactive oxygen species scavengers, and throttling of linear electron flow by antenna uncoupling. During recovery from HS, cells appear to focus on processes allowing rapid resumption of growth rather than restoring pre-HS conditions.
Public Attention, Political Action: the Example of Environmental Regulation

In this paper, a rational choice model of the dynamics of public attention to politically relevant issues is proposed, responding to the following research questions: When and why does public attention arise in the . rst place? Do ‘issue attention cycles’ really exist? What issues are likely to attain which degree of public attention? How can public attention be measured soundly? In which way does public attention in.uence regulatory action, and how, in turn, is public attention affected by political action? To this end, the paper sets off with a discussion of the concepts of ‘public’, ‘issue’, ‘attention’ and ‘cycle’. Key variables of the causal model include the acuteness/severity and accessibility/visibility of the issue at stake, as well as the ability to ‘solve’ the underlying problem. In an empirical study, several environmental issues and their corresponding regulation in Germany are examined in order to test the theoretical conjectures which could, for the most part, be empirically supported.
Bone Morphogenetic Protein (BMP) Type II Receptor Deletion Reveals BMP Ligand-specific Gain of Signaling in Pulmonary Artery Smooth Muscle Cells*

Bone morphogenetic protein (BMP) ligands signal by binding the BMP type II receptor (BMPR2) or the activin type II receptors (ActRIIa and ActRIIb) in conjunction with type I receptors to activate SMADs 1, 5, and 8, as well as members of the mitogen-activated protein kinase family. Loss-of-function mutations in Bmpr2 have been implicated in tumorigenesis and in the etiology of primary pulmonary hypertension. Because several different type II receptors are known to recognize BMP ligands, the specific contribution of BMPR2 to BMP signaling is not defined. Here we report that the ablation of Bmpr2 in pulmonary artery smooth muscle cells, using an ex vivo conditional knock-out (Cre-lox) approach, as well as small interfering RNA specific for Bmpr2, does not abolish BMP signaling. Disruption of Bmpr2 leads to diminished signaling by BMP2 and BMP4 and augmented signaling by BMP6 and BMP7. Using small interfering RNAs to inhibit the expression of other BMP receptors, we found that wild-type cells transduce BMP signals via BMPR2, whereas BMPR2-deficient cells transduce BMP signals via ActRIIa in conjunction with a set of type I receptors distinct from those utilized by BMPR2. These findings suggest that disruption of Bmpr2 leads to the net gain of signaling by some, but not all, BMP ligands via the activation of ActRIIa.
