Efficient, Long-Term Logging of Rich Data Sensors Using Transient Sensor Nodes

While energy harvesting is generally seen to be the key to power cyber-physical systems in a low-cost, long-term, efficient manner, it has generally required large energy storage devices to mitigate the effects of the source’s variability. The emerging class of transiently powered systems embrace this variability by performing computation in proportion to the energy harvested, thereby minimizing the obtrusive and expensive storage element. By using an efficient Energy Management Unit (EMU), small bursts of energy can be buffered in an optimally sized capacitor and used to supply generic loads, even when the average harvested power is only a fraction of that required for sustained system operation. Dynamic Energy Burst Scaling (DEBS) can be used by the load to dynamically configure the EMU to supply small bursts of energy at its optimal power point, independent from the harvester’s operating point. Parameters like the maximum burst size, the solar panel’s area, as well as the use of energy-efficient Non-Volatile Memory Hierarchy (NVMH) can have a significant impact on the transient system’s characteristics such as the wake-up time and the amount of work that can be done per unit of energy. Experimental data from a solar-powered, long-term autonomous image acquisition application show that, regardless of its configuration, the EMU can supply energy bursts to a 43.4mW load with efficiencies of up to 79.7% and can work with input power levels as low as 140μW. When the EMU is configured to use DEBS and NVMH, the total energy cost of acquiring, processing and storing an image can be reduced by 77.8%, at the price of increasing the energy buffer size by 65%.
Mitigation of 5-fluorouracil–induced liver damage in rats by vitamin C via targeting redox–sensitive transcription factors

Adverse complications associated with antineoplastic drug-based cancer therapy are the major clinical drawbacks. Oxidative stress and inflammation play a major role in the damage due to cancer therapy. In the current study, we investigated the modulatory effect of vitamin C (Vit. C) on liver toxicity induced by 5-fluorouracil (5-FU) in rats. Animals were divided into four groups. Animals in group I received vehicle. Oral gavage of Vit. C (500 mg kg−1 body weight (b.wt.)) was given to the animals in group III and group IV. 5-FU (150 mg kg−1 b.wt.) was injected intraperitoneally to the animals in group II and group III. Findings of the present study revealed that oral administration of Vit. C significantly ameliorated the level of lipid peroxidation and the activity of myeloperoxidase. Vit. C administration markedly reduced the activation of nuclear factor κB and expression of cyclooxygenase 2, whereas nuclear translocation of nuclear factor erythroid 2–related factor 2 was increased. Hepatic histopathological analyses further supported the protective effect of Vit. C. Findings of the current study demonstrate that the toxic free radicals and inflammatory mediators generated due to chemotherapy play a critical role in 5-FU–induced hepatic damage. Attenuating action of Vit. C may be due to the modulation of redox-sensitive transcription factors and associated target molecules.
Focused attention in anhedonia: a P3 study.

Attentional and information processing impairments have been evidenced in nonclinical anhedonic subjects. However, the extent of attentional deficit has not been determined. We studied focused attention, the ability to reject irrelevant or distracting messages, in anhedonic nonclinical subjects. The event-related potentials and behavioral performances of anhedonic subjects were compared with those of control subjects during the Eriksen focused attention task (C.W. Eriksen & B.A. Eriksen, 1974); the task combined one compatible and one incompatible condition, the latter causing an interference. Anhedonic subjects exhibited a smaller P300 and slower reaction times than control subjects. Varying task conditions had different effects on anhedonic subjects and controls, suggesting that anhedonic subjects may have developed a conservative response strategy. In view of previous works, these results suggest that attentional impairment is not ascribed to specific processes, but may involve a more global deficit, that is, a resource allocation deficit.
USER-GENERATED CONTENT AS WORD-OF-MOUTH

The objective of this research is to identify two harvestable word-of-mouth (WOM) proxies and test their construct validity. Bivariate measures of association of user-generated content (UGC) data compiled from Facebook.com on sixty-one firms across nine markets suggest the WOM proxies were positively correlated, maintaining varying relationships with firms’ stock market performance. Study two uses time-series analysis to demonstrate that these WOM proxies change in tandem with stock prices, implying that they are sensitive to firm behaviors and that UGC is a leading indicator of stock market performance. As such, the findings provide managers with a tool to more accurately assess impressions of the firm.
Detection and Isolation of Campylobacter Species Other than C. jejuni from Children with Crohn's Disease

ABSTRACT The presence of Campylobacter species other than Campylobacter jejuni and antibodies to Campylobacter concisus in children were investigated. A significantly greater presence of C. concisus and higher levels of antibodies to C. concisus were detected in children with Crohn's disease (CD) than in controls. Campylobacter species other than C. jejuni were isolated from intestinal biopsy specimens of children with CD.
Prognostic Factors after Primary Vitrectomy and Perfluorocarbon Liquids for Bullous Rhegmatogenous Retinal Detachment

Purpose To identify prognostic factors for visual acuity and anatomic outcomes associated with bullous rhegmatogenous retinal detachment (RRD) management using primary pars plana vitrectomy, intraoperative perfluorocarbon liquids (PFCLs), and internal gas tamponade. Methods The authors studied a consecutive series of 115 eyes (115 patients) with a bullous RRD not complicated by proliferative vitreoretinopathy (PVR) associated with large, multiple, and/or posterior breaks in 58 (50.4%) eyes. All eyes underwent vitrectomy, injection of PFCL, and gas tamponade as the primary procedure. Encircling scleral bands were placed in all cases. The follow-up period ranged from 3 to 60 months (mean 16.6±14.1 months). Results Retinal reattachment was achieved in 92.2% of eyes (106/115) with one operation and in all eyes after a second procedure. PVR was observed in 1 (0.87%) eye and pre-retinal membranes in 3 (2.6%) eyes. Progression of pre-existing cataract and development of new cataract occurred in 45 (58.4%) of the 77 phakic eyes. The presence of inferior retinal breaks was significantly associated with redetachment after the first procedure (p=0.0156). On univariate analysis, better preoperative visual acuity (p<0.001), macular sparing retinal detachment (p<0.001), and fewer quadrants involved by the detachment (p=0.0015) were significant positive prognostic factors for final visual acuity. Logistic regression analysis highlighted that macular sparing retinal detachment and absence of trauma were associated with better final visual acuity. Conclusions Redetachment was associated with the presence of inferior retinal breaks. Visual recovery was dependent on preoperative visual acuity, macular involvement, extent of retinal detachment, and trauma.

Decoding sequence-level information to predict membrane protein expression

The expression of integral membrane proteins (IMPs) remains a major bottleneck in the characterization of this important protein class. IMP expression levels are currently unpredictable, which renders the pursuit of IMPs for structural and biophysical characterization challenging and inefficient. Experimental evidence demonstrates that changes within the nucleotide or amino-acid sequence for a given IMP can dramatically affect expression; yet these observations have not resulted in generalizable approaches to improved expression. Here, we develop a data-driven statistical predictor named IMProve, that, using only sequence information, increases the likelihood of selecting an IMP that expresses in E. coli. The IMProve model, trained on experimental data, combines a set of sequence-derived features resulting in an IMProve score, where higher values have a higher probability of success. The model is rigorously validated against a variety of independent datasets that contain a wide range of experimental outcomes from various IMP expression trials. The results demonstrate that use of the model can more than double the number of successfully expressed targets at any experimental scale. IMProve can immediately be used to identify favorable targets for characterization.
Though Forced, Still Valid: Psychometric Equivalence of Forced-Choice and Single-Statement Measures

Forced-choice (FC) measures are gaining popularity as an alternative assessment format to single-statement (SS) measures. However, a fundamental question remains to be answered: Do FC and SS instruments measure the same underlying constructs? In addition, FC measures are theorized to be more cognitively challenging, so how would this feature influence respondents’ reactions to FC measures compared to SS? We used both between- and within-subjects designs to examine the equivalence of the FC format and the SS format. As the results illustrate, FC measures scored by the multi-unidimensional pairwise preference (MUPP) model and SS measures scored with the generalized graded unfolding model (GGUM) showed strong equivalence. Specifically, both formats demonstrated similar marginal reliabilities and test-retest reliabilities, high convergent validities, good discriminant validities, and similar criterion-related validities with theoretically relevant criteria. In addition, the formats had little differential impact on respondents’ general emotional and cognitive reactions except that the FC format was perceived to be slightly more difficult and more time-saving.
Bis{6-methoxy-2-[(4-methylphenyl)iminiomethyl]phenolate-κ2 O,O′}tris(nitrato-κ2 O,O′)holmium(III) monohydrate

The crystal structure of the title compound, [Ho(NO3)3(C15H15NO2)2]·H2O, contains two Schiff base 6-methoxy-2-[(4-methylphenyl)iminiomethyl]phenolate (L) ligands, three independent nitrate ions that chelate to the HoIII ion with O atoms and a hydrate water molecule. The coordination environment of the HoIII ion is ten-coordinate. The L ligands chelate with a strong Ho—O(phenolate) bond and weaker Ho—O(methoxy) contacts. The latter can be interpreted as the apices of the bicapped square–antiprismatic [HoO10] polyhedron. Intermolecular N—H⋯O hydrogen bonds occur. Intramolecular O—H⋯O interactions link the complex molecules and uncoordinated water molecules.
Environmental health assessment of communities across Canada: contextual factors study of the Canadian Alliance for Healthy Hearts and Minds

ABSTRACT Rationale: Cardiovascular risk varies across communities in Canada. Community-level differences in contextual factors may influence risk factor development. Methods: We audited urban and rural Canadian communities using a standardized instrument to collect objective measures of demographic, public transport, tobacco, grocery, alcohol, and healthful restaurant options. We duplicated 209 audits to assess reliability. Results: Of 2074 communities audited between 2014 and 2016, 83.5% were urban. Provincial and urban-rural differences exist in fruit and vegetable availability. Rural communities face higher food prices, are subject to more seasonal variation in fruit and vegetable selection, and generally see less promotion of healthy choices and nutritional information in restaurants than urban communities. In-store advertising for sweet drinks and junk food is more frequent than advertisements for tobacco products. Cigarette prices are lower and variety higher in urban than rural communities, and lowest in central Canada. Alcohol prices are lowest in Quebec. The intra-rater reliability of the audits was high. We created an on-line map for public use. Conclusions: Provincial and urban-rural differences exist for contextual determinants of health. Public health and built environment professionals and government officials should use these data to develop unified federal and provincial strategies to reduce Canada’s chronic disease burden.
[Volar locking plate fixation of unstable distal radius fractures].

OBJECTIVES We evaluated radiographic and functional results of volar locking plate fixation of unstable distal radius fractures. METHODS The study included 27 patients (15 males, 12 females; mean age 45 years; range 18 to 77 years) who were treated with volar locking plate fixation for unstable distal radius fractures. Twenty-two patients (81.5%) had AO type C and five (18.5%) had type B fractures. Two patients (7.4%) had type I open fractures. Dorsal and volar angulation were present in 21 (77.8%) and six (22.2%) fractures, respectively. Four patients (14.8%) also had elbow dislocation and/or fracture and nine patients (33.3%) had disruption of the distal radioulnar joint. Autologous iliac crest graft was used in 10 patients (37%). Postoperative assessments included range of movement and grip strength measurements, and radiographic parameters using the Stewart criteria. Functional results were assessed using the Q-DASH (Quick-Disabilities of the Arm, Shoulder and Hand) questionnaire and the Gartland-Werley scale. The mean follow-up was 18 months (range 12 to 34 months). RESULTS All fractures united without a problem within a mean of 6.5 weeks (range 6 to 8 weeks). The following parameters became equal to the unaffected side: ulnar variance (n=21, 77.8%), radial inclination angle (n=13, 48.2%), radial tilt angle (n=8, 29.6%), and radial height (n=11, 40.7%). The mean radiographic Stewart score was 0.5 (range 0 to 3). The mean grip strength of the operated side was 72.4% (18 kg) of the normal side. The mean Q-DASH and Gartland-Werley scores were 8.3 (range 0 to 70.5) and 4.7 (range 0 to 16), respectively. According to the Gartland-Werley scale, the results were excellent in 12 patients (44.4%), good in 12 patients, and moderate in three patients (11.1%). Three complications (11.1%) occurred, including loss of alignment in two patients, and screw-related discomfort in one patient. CONCLUSION Volar locking plate fixation is an effective treatment in the anatomical and functional restoration of unstable distal radius fractures.
AlGaN-GaN HEMTs on Si with power density performance of 1.9 W/mm at 10 GHz

AlGaN-GaN high electron mobility transistors (HEMTs) on silicon substrate are fabricated. The device with a gate length of 0.3-/spl mu/m and a total gate periphery of 300 /spl mu/m, exhibits a maximum drain current density of 925 mA/mm at V/sub GS/=0 V and V/sub DS/=5 V with an extrinsic transconductance (g/sub m/) of about 250 mS/mm. At 10 GHz, an output power density of 1.9 W/mm associated to a power-added efficiency of 18% and a linear gain of 16 dB are achieved at a drain bias of 30 V. To our knowledge, these power results represent the highest output power density ever reported at this frequency on GaN HEMT grown on silicon substrates.
Gender differences in depressive symptom profiles and patterns of psychotropic drug usage in Asian patients with depression: Findings from the Research on Asian Psychotropic Prescription Patterns for Antidepressants study

Objectives: The purpose of this study was to investigate whether there were gender-specific depressive symptom profiles or gender-specific patterns of psychotropic agent usage in Asian patients with depression. Method: Clinical data from the Research on Asian Psychotropic Prescription Patterns for Antidepressant study (1171 depressed patients) were used to determine gender differences by analysis of covariates for continuous variables and by logistic regression analysis for discrete variables. In addition, a binary logistic regression model was fitted to identify independent clinical correlates of the gender-specific pattern on psychotropic drug usage. Results: Men were more likely than women to have loss of interest (adjusted odds ratio = 1.379, p = 0.009), fatigue (adjusted odds ratio = 1.298, p = 0.033) and concurrent substance abuse (adjusted odds ratio = 3.793, p = 0.008), but gender differences in other symptom profiles and clinical features were not significant. Men were also more likely than women to be prescribed adjunctive therapy with a second-generation antipsychotic (adjusted odds ratio = 1.320, p = 0.044). However, men were less likely than women to have suicidal thoughts/acts (adjusted odds ratio = 0.724, p = 0.028). Binary logistic regression models revealed that lower age (odds ratio = 0.986, p = 0.027) and current hospitalization (odds ratio = 3.348, p < 0.0001) were independent clinical correlates of use of second-generation antipsychotics as adjunctive therapy for treating depressed Asian men. Conclusion: Unique gender-specific symptom profiles and gender-specific patterns of psychotropic drug usage can be identified in Asian patients with depression. Hence, ethnic and cultural influences on the gender preponderance of depression should be considered in the clinical psychiatry of Asian patients.
Hepatitis C Virus Infection Causes Cell Cycle Arrest at the Level of Initiation of Mitosis

ABSTRACT Chronic infection with the hepatitis C virus (HCV) is associated with increased risk for hepatocellular carcinoma (HCC). Chronic immune-mediated inflammation is likely to be an important factor in the development of HCV-associated HCC, but direct effects of HCV infection on the host cell cycle may also play a role. Although overexpression studies have revealed multiple interactions between HCV-encoded proteins and host cell cycle regulators and tumor suppressor proteins, the relevance of these observations to HCV-associated liver disease is not clear. We determined the net effect of these interactions on regulation of the cell cycle in the context of virus infection. Flow cytometry of HCV-infected carboxyfluorescein succinimidyl ester-labeled hepatoma cells indicated a slowdown in proliferation that correlated with abundance of viral antigen. A decrease in the proportions of infected cells in G1 and S phases with an accumulation of cells in G2/M phase was observed, compared to mock-infected controls. Dramatic decreases in markers of mitosis, such as phospho-histone H3, in infected cells suggested a block to mitotic entry. In common with findings described in the published literature, we observed caspase 3 activation, suggesting that cell cycle arrest is associated with apoptosis. Differences were observed in patterns of cell cycle disturbance and levels of apoptosis with different strains of HCV. However, the data suggest that cell cycle arrest at the interface of G2 and mitosis is a common feature of HCV infection.
AN EFFECTIVE TOOL FOR ENHANCING THE STATIC BACKCALCULATION OF PAVEMENT MODULI

The Falling Weight Deflectometer (FWD) test is one of the most commonly used tools for nondestructive evaluation of flexible pavements. Although the test is intrinsically dynamic in nature, the state-of-practice backcalculation techniques that are used to interpret the FWD records are primarily elastostatic-based owing in part to the high computational cost of dynamic multi-layered solutions. It has long been known that the foregoing discrepancy may lead to considerable systematic errors in the estimation of pavement moduli in situations where the inertial and resonance phenomena are pronounced due to the presence of bedrock or seasonal stiff layer. In this investigation, a simple, yet effective algorithm is proposed that allows the static backcalculation analyses to perform well even when dynamic effects are significant. The technique is based on the use of the Discrete Fourier Transform as a pre-processing tool, which filters the dynamic effects and extracts the static pavement response from transient FWD records. With the use of the filtered (i.e. zero-frequency) force and deflection values in lieu of their peak counterparts, the static backcalculation can be further performed in a conventional manner, but free of inconsistencies associated with the neglect of dynamic effects. Illustrative results based on synthetic deflection records demonstrate a marked improvement in the elastostatic prediction of pavement moduli when the proposed modification is used. The filtering algorithm can be implemented on a personal computer as a pre-processor for the conventional FWD data interpretation, requiring only a minimal increase in the computational effort required to backcalculate the pavement moduli.

Night-time lights time series of tsunami damage, recovery, and economic metrics in Sumatra, Indonesia

On 26 December 2004, a magnitude 9.2 earthquake off the west coast of the northern Sumatra, Indonesia, resulted in 160,000 Indonesians killed. We examine the Defense Meteorological Satellite Program-Operational Linescan System night-time light imagery brightness values for 307 communities in the Study of the Tsunami Aftermath and Recovery (STAR), a household survey in Sumatra from 2004 to 2008. We examined nightlight time series between the annual brightness and extent of damage, economic metrics collected from STAR households and aggregated to the community level. There were significant changes in brightness values from 2004 to 2008 with a significant drop in brightness values in 2005 due to the tsunami and pre-tsunami night-time light values returning in 2006 for all damage zones. There were significant relationships between the night-time imagery brightness and per capita expenditures, and spending on energy and on food. Results suggest that Defense Meteorological Satellite Program night-time light imagery can be used to capture the impacts and recovery from the tsunami and other natural disasters and estimate time series economic metrics at the community level in developing countries.
