Power quality of energy saving lamps under wide voltage variations

PLN, State-owned Electricity Company in Indonesia has been promoting energy saving lamps (ESLs) through demand-side management (DSM) program since 2005. As a result, those lamps are widely used in Indonesia. To avoid outages on the customers, a brownout strategy (voltage reduction) is sometimes used. The lamps are in this case operated at a lower voltage than their rating. The paper aims to investigate the effect on power quality of those voltage variations through a laboratory test. Value of harmonics, power factor and waveform of ESLs were analyzed. The test relates to 16 sample lamps commonly used in residential and commercial area, divided in 11 LED lamps and 5 CFLs covering different manufacturers and different power ratings. The experiment uses power meter to obtain the electrical characteristics. The supply voltage applied during testing was generated by an ideal power source without voltage harmonics to avoid effects linked to device non-linear behavior. The test results show that 4 types of LEDs and 2 types of CFLs can be identified based upon the input current waveform. However, their responses under voltage amplitude variation differ. This paper focuses on this specific electrical property, which is not readily documented. It was observed that only a few ESLs have low level of harmonic currents and high power factor, in concordance with low sensitivity to amplitude variations. Moreover, the experimental results are compared with the standard harmonic limit allowable for lighting load as per IEC 61000-3-2.
Spitzer Observations of the z = 2.73 Lensed Lyman Break Galaxy: MS 1512–cB58

We present Spitzer infrared (IR) photometry and spectroscopy of the lensed Lyman break galaxy (LBG) MS 1512–cB58 at z = 2.73. The large (factor ~30) magnification allows for the most detailed IR study of an L*UV(z = 3) LBG to date. Broadband photometry with IRAC (3-10 μm), IRS (16 μm), and MIPS (24, 70, and 160 μm) was obtained, as well as IRS spectroscopy spanning 5.5-35 μm. A fit of stellar population models to the optical/near-IR/IRAC photometry gives a young age (~9 Myr), forming stars at ~98 M☉ yr−1, with a total stellar mass of ~109 M☉ formed thus far. The existence of an old stellar population with twice the stellar mass cannot be ruled out. IR spectral energy distribution fits to the 24 and 70 μm photometry, as well as previously obtained submillimeter/millimeter data give an intrinsic IR luminosity LIR = (1–2) × 1011 L☉ and a star formation rate (SFR) ~20-40 M☉ yr−1. The ultraviolet (UV) derived SFR is ~3-5 times higher than the SFR determined using LIR or LH α because the red UV spectral slope is significantly overpredicting the level of dust extinction. This may suggest that the assumed Calzetti starburst obscuration law is not valid in young LBGs. We detect strong line emission from polycyclic aromatic hyrdrocarbons (PAHs) at 6.2, 7.7, and 8.6 μm. The line ratios are consistent with ratios observed in both local and high-redshift starbursts. Both the PAH and rest-frame 8 μm luminosities predict the total LIR based on previously measured relations in starbursts. Finally, we do not detect the 3.3 μm PAH feature. This is marginally inconsistent with some PAH emission models, but still consistent with PAH ratios measured in many local star-forming galaxies.
Wavelet Denoising Based on the MAP Estimation Using the BKF Prior With Application to Images and EEG Signals

This paper presents a novel nonparametric Bayesian estimator for signal and image denoising in the wavelet domain. This approach uses a prior model of the wavelet coefficients designed to capture the sparseness of the wavelet expansion. A new family of Bessel K Form (BKF) densities are designed to fit the observed histograms, so as to provide a probabilistic model for the marginal densities of the wavelet coefficients. This paper first shows how the BKF prior can characterize images belonging to Besov spaces. Then, a new hyper-parameters estimator based on EM algorithm is designed to estimate the parameters of the BKF density; and, it is compared with a cumulants-based estimator. Exploiting this prior model, another novel contribution is to design a Bayesian denoiser based on the Maximum A Posteriori (MAP) estimation under the 0–1 loss function, for which we formally establish the mathematical properties and derive a closed-form expression. Finally, a comparative study on a digitized database of natural images and biomedical signals shows the effectiveness of this new Bayesian denoiser compared to other classical and Bayesian denoising approaches. Results on biomedical data illustrate the method in the temporal as well as the time-frequency domain.
FLAG-liposomal Doxorubicin (Myocet) Regimen for Refractory or Relapsed Acute Leukemia Pediatric Patients

Despite the success in treating the majority of children with newly diagnosed acute leukemia, children with relapsed or refractory disease are an exceptionally difficult group of patients to cure. We assessed the combination of fludarabine with cytarabine and granulocyte colony-stimulating factor (FLAG) and nonpegylated liposomal doxorubicin (Myocet) in children with either acute lymphoblastic leukemia (ALL) or acute myelogenous leukemia (AML) refractory to first-line therapy or who had relapsed after risk-tailored chemotherapy. We treated 35 patients with FLAG-Myocet. The median age at treatment was 9 years and 7 months (range, 1 to 18 y). The 94% of ALL patients (16/17) and the 61% AML patients (11/18) achieved complete remission after FLAG-Myocet. A partial response was observed in the 17% of AML patients (3/18). Twenty-eight of 35 (80%) patients received hematopoetic stem cell transplantation in remission induced by FLAG-Myocet regimen. The ALL and AML overall survival at 3 years after FLAG-Myocet is 33% and 38%, respectively. The probability of ALL and AML event-free survival at 3 years after FLAG-Myocet is 33% and 40%, respectively. The probability of ALL and AML disease-free survival at 3 years after hematopoietic stem cell transplantation is 19% and 58%, respectively. Nonhematological toxicity was remarkably low, while almost all patients showed severe hematological toxicity. FLAG-Myocet is an efficient and a well-tolerated regimen that allows nearly all patients to undergo hematopoetic stem cell transplantation. FLAG-Myocet proved to be safe in terms of acute cardiac toxicity although particular care must be taken to reduce infectious complications due to severe myelosuppression. The promising results shown in our study need to be confirmed by larger and possibly randomized trials.
PERSONALITY AND SOCIAL PSYCHOLOGY BULLETIN Harmon-Jones / COGNITIVE DISSONANCE AND NEGATIVE AFFECT Cognitive Dissonance and Experienced Negative Affect: Evidence That Dissonance Increases Experienced Negative Affect Even in the Absence of Aversive Consequences

Research has suggested that the dissonance produced in the induced compliance paradigm is accompanied by experienced negative affect. This research, however, used a paradigm in which participants’ counterattitudinal action had the potential to bring about an aversive consequence, thus leaving the question of whether the dissonance produced in the absence of aversive consequences causes increased negative affect. Results from two experiments demonstrated that individuals report more negative affect following freely choosing (high choice) than following being told (low choice) to write a counterattitudinal statement that would produce no aversive consequences. The second experiment also demonstrated that the negative affect is reduced following attitude change and eliminated an alternative explanation of similar, past experiments. Discussion focuses on the implications of these findings.
When Engagement Meets Similarity: Efficient (k, r)-Core Computation on Social Networks

In this paper, we investigate the problem of (k,r)-core which intends to find cohesive subgraphs on social networks considering both user engagement and similarity perspectives. In particular, we adopt the popular concept of k-core to guarantee the engagement of the users (vertices) in a group (subgraph) where each vertex in a (k,r)-core connects to at least k other vertices. Meanwhile, we consider the pairwise similarity among users based on their attributes. Efficient algorithms are proposed to enumerate all maximal (k,r)-cores and find the maximum (k,r)-core, where both problems are shown to be NP-hard. Effective pruning techniques substantially reduce the search space of two algorithms. A novel (k,k')-core based (k,r)-core size upper bound enhances performance of the maximum (k,r)-core computation. We also devise effective search orders for two mining algorithms where search priorities for vertices are different. Comprehensive experiments on real-life data demonstrate that the maximal/maximum (k,r)-cores enable us to find interesting cohesive subgraphs, and performance of two mining algorithms is effectively improved by proposed techniques.
Comparison of Pain During Two Methods of Urine Collection in Preterm Infants

BACKGROUND: Suprapubic aspiration (SPA) and urine catheterization (UC) are performed frequently in preterm neonates to rule out urinary tract infection; however, a comparison of the pain caused by both procedures has not been made previously. OBJECTIVE: To compare pain responses in preterm infants who are undergoing urine collection by using SPA versus UC. METHODS: Prospective, single-blind, randomized clinical trial was conducted in 2 NICUs. Preterm infants who required urine samples for microbiologic analysis were randomly assigned to undergo either SPA or UC. The infants' facial and physiologic responses were videotaped during the procedure and later scored by a research assistant who was blind to the method of urine collection. The primary outcome measure was facial-grimacing during the procedure, which was assessed by measuring the percentage of time the infants displayed brow-bulging. Secondary outcomes included changes in heart rate (beats per minute), oxygen saturation (%), and procedural success rate. RESULTS: Forty-eight preterm infants participated. Characteristics did not differ (P > .05) between groups. The mean (SD) percent brow-bulging score was higher in the SPA group than in the UC group (67% [34] vs 42% [38]; P = .02). Heart rate and oxygen saturation did not differ (P = .50 and .74, respectively). The procedure-success rate, although lower in the SPA group, was not statistically different (60% vs 78%; P = .17). CONCLUSIONS: SPA was more painful than UC, as assessed by brow-bulging, and had a tendency to be associated with a higher rate of procedure failure. These findings should be taken into consideration when choosing between these 2 procedures for preterm infants who undergo urine sampling.
Initial low/hard state, multiple jet ejections and X-ray/radio correlations during the outburst of XTE J1859+226

We have studied the 1999 soft X-ray transient outburst of XTE J1859+226 at radio and X-ray wavelengths. The event was characterized by strong variability in the disc, corona and jet - in particular, a number of radio flares (ejections) took place and seemed well-correlated with hard X-ray events. Apparently unusual for the canonical 'soft' X-ray transient, there was an initial period of low/hard state behaviour during the rise from quiescence but prior to the peak of the main outburst - we show that not only could this initial low/hard state be a ubiquitous feature of soft X-ray transient outbursts, but also it could be extremely important in our study of outburst mechanisms.
MULTISCALE TOTAL VARIATIONAL ALGGORITHMS FOR DENOISING NATURAL COLOR PHOTOS IN DIGITAL PHOTOGRAPHY

As digital photography rapidly replacing the traditional film photography as the photography of choice for all but a few devoted professionals, post image processing of natural color photos such as denoising becomes increasingly an integral part of digital photography. Although many denoising schemes have been designed, almost none specifically target natural color photos. Noise in natural color photos have special characteristics that are substantially different from those that have been added artificially. In this paper we propose the multiscale total variational method (MTV) for denoising. Standing alone the MTV method is effective in denoising monochromatic images. However, it demonstrates outstanding denoising capabilities for natural color images. Key to the success is the understanding of the characteristics of digital noise in natural color images as well as a non-traditional color space we have introduced specifically for the purpose. An automatic stopping criterion is applied to each channel to prevent over processing. 1. Noise In Natural Color Photos With the surging popularity of digital cameras, digital photography is rapidly replacing the traditional film photography as the photography of choice for virtually all but a few devoted professionals. In digital photography, post image processing is an integral part for obtaining better images even for the casual picture takers. Post image processing is especially important for people who are willing to go beyond point-and-shoot, and one of the key steps in image processing is denoising. All digital cameras today take color photos. (Some cameras allow for black-and-white images, but these are converted from color images using in-camera firmwares.) Noise is present in virtually all digital photos, and there are several sources for it. When light (photons) strike the image sensor, electrons are produced. These “photoelectrons” give rise to analog signals which are then converted into digital pixels by an Analog to Digital
Comparison of the Safety, Tolerability, and Pharmacokinetic Profile of a Single Oral Dose of Pitavastatin 4 mg in Adult Subjects With Severe Renal Impairment Not on Hemodialysis Versus Healthy Adult Subjects

Abstract: Pitavastatin is a novel statin recently approved in the United States as an adjunctive therapy with diet to reduce elevated total cholesterol, low-density lipoprotein cholesterol, apolipoprotein B, and triglycerides and to increase high-density lipoprotein cholesterol. This open-label study enrolled 16 subjects as follows: group A: 8 adult subjects with severe renal impairment who were not on hemodialysis (estimated glomerular filtration rate of 15–29 mL/min/1.73 m2) and group B: 8 healthy adult subjects (estimated glomerular filtration rate ≥80 mL/min/1.73 m2). On day 1, the subjects received a single oral dose of pitavastatin 4 mg and remained in the clinic on days 1–3 for safety and pharmacokinetic assessments. Comparing group A with group B, the geometric mean ratio of AUC0–inf for pitavastatin was 1.36 (90% confidence interval, 0.88–2.11). For Cmax, the corresponding ratio was 1.18 (90% confidence interval, 0.68–2.02). There were no severe treatment-emergent adverse events (AEs), serious AEs, deaths, or treatment-emergent AEs leading to study drug discontinuation. A single dose of pitavastatin 4 mg was safe and well tolerated by the subjects in this study with severe renal impairment, who were not on hemodialysis.
UCT for Tactical Assault Planning in Real-Time Strategy Games

We consider the problem of tactical assault planning in real-time strategy games where a team of friendly agents must launch an assault on an enemy. This problem offers many challenges including a highly dynamic and uncertain environment, multiple agents, durative actions, numeric attributes, and different optimization objectives. While the dynamics of this problem are quite complex, it is often possible to provide or learn a coarse simulation-based model of a tactical domain, which makes Monte-Carlo planning an attractive approach. In this paper, we investigate the use of UCT, a recent Monte-Carlo planning algorithm for this problem. UCT has recently shown impressive successes in the area of games, particularly Go, but has not yet been considered in the context of multiagent tactical planning. We discuss the challenges of adapting UCT to our domain and an implementation which allows for the optimization of user specified objective functions. We present an evaluation of our approach on a range of tactical assault problems with different objectives in the RTS game Wargus. The results indicate that our planner is able to generate superior plans compared to several baselines and a human player.
TRADD Domain of Epstein-Barr Virus Transforming Protein LMP1 Is Essential for Inducing Immortalization and Suppressing Senescence of Primary Rodent Fibroblasts

ABSTRACT Mutation analysis of latent membrane protein 1 (LMP1) in Epstein-Barr virus (EBV)-induced B-cell immortalization revealed two transformation effector sites, TES1 and TES2. TES2 mediates the interaction with tumor necrosis factor receptor-associated death domain protein (TRADD) and plays a key role in transactivating NF-κB and AP-1. Recombinant EBV containing LMP1 with TES2 deleted induces a limited proliferation of B cells. The present study shows that a mutant with an LMP1 site-specific mutation at TES2, LMP1TRADD, initially stimulates cell growth and significantly extends the life span of MEF. However, it is not sufficient for the immortalization of MEF, and MEF-LMP1TRADD cells eventually enter growth arrest. Further analysis reveals that although LMP1TRADDpromotes cell growth, it does not prevent the eventual onset of senescence and the expression of tumor suppressor p16Ink4a.
Antioxidant defense system in prostate adenocarcinoma and benign prostate hyperplasia of elderly patients.

UNLABELLED Prostate adenocarcinoma (PC) and benign prostate hyperplasia (BPH) are age-related diseases. The augmented oxidative stress is suggested to play an important role in the pathogenesis of both mentioned prostate disorders. In the presented study the antioxidant defense system in PC and BPH patients has been evaluated. The study was carried out on 30 PC patients (age 61±8 years) and 30 BPH patients (age 63±8 years). The control group consisted of 25 healthy men (age 61±14 years). The reduced glutathione (GSH) concentrations in the erythrocytes and the activities of plasma superoxide dismutase (EC-SOD), plasma glutathione peroxidase (GPx-3), erythrocyte glutathione peroxidase (GPx-1) and erythrocyte glutathione S-transferase (GST) were measured in the examined groups. GSH concentrations in the erythrocytes and plasma GPx-3 activities in the PC group (2.31±0.27 mmol/l and 186.2±39 U/l, respectively) were significantly lower (P<0.05) as compared with the control group (2.52±0.24 and 211.8±26, respectively) and the BPH group (2.45±0.27 and 206.6±48, respectively). Erythrocyte GPx-1 activities in the BPH patients (14.76±3.5 U/g Hb) were statistically decreased (P<0.05) than in the healthy people (16.94±3.7) and in the PC patients (16.82±3.7). There were no significant differences in the activities of GST and EC-SOD between the PC group (2.72±1.34 nmol CDNB-GSH/mg Hb/min and 19.33±4.4 U/ml, respectively), the BPH group (2.53±1.00 and 19.22±4.8, respectively) and the controls (2.88±0.82 and 19.40±4.1, respectively). These results indicate that antioxidant defense system is decreased in the elderly patients with PC and BPH. The differences in the antioxidative system between examined groups of patients may suggest the different etiologies of both diseases. KEYWORDS antioxidative enzymes, antioxidant defense system, glutathione, benign prostate hyperplasia, prostate adenocarcinoma.
Multi-Scale Triplet CNN for Person Re-Identification

Person re-identification aims at identifying a certain person across non-overlapping multi-camera networks. It is a fundamental and challenging task in automated video surveillance. Most existing researches mainly rely on hand-crafted features, resulting in unsatisfactory performance. In this paper, we propose a multi-scale triplet convolutional neural network which captures visual appearance of a person at various scales. We propose to optimize the network parameters by a comparative similarity loss on massive sample triplets, addressing the problem of small training set in person re-identification. In particular, we design a unified multi-scale network architecture consisting of both deep and shallow neural networks, towards learning robust and effective features for person re-identification under complex conditions. Extensive evaluation on the real-world Market-1501 dataset have demonstrated the effectiveness of the proposed approach.
Efficiency of classification techniques for sachen and rupal glaciers variation during 1972–2010

Remote Sensing and GIS has been used effectively to analyze glaciers dynamics. In this paper a comparative analysis of supervised, knowledge based and object based classification techniques have been carried out to map debris and clean ice of sachen and rupal glaciers. Assessment of glaciers temporal variation plays an important role to identify the rate of retreat and advance over a certain period of time. Sachen and Rupal glaciers lying in astore valley have been used as an input for analysis. The area of debris cover and clean ice derived from the classification used have been visualized and compared with the reference classification. Reference classification, derived from standard classification technique further refined by manual editing to obtain highly accurate results. The results from this classification show that Sachen and Rupal glaciers have lost around 2% and 13% of their glaciated area respectively over the last thirty years.
Terahertz thermometry system to measure temperature in the thickness of a solid polymer*

Abstract This paper deals with thermal attenuation of a transmitted THz signal (165 GHz) across a POM polymer sample subjected to a thermal gradient in the thickness direction. The paper describes the experimental setup, including a THz sensor, a system to impose thermal loading and an infrared camera used to measure temperature variations at the surface. The thermal dependence of the transmitted THz signal through the sample was studied along a spatial profile. A simple polynomial model, validated through finite element analysis and thermal imaging measurement, was used to estimate temperature variations in the thickness direction. The correspondence between the 2D transmitted THz signal and the 3D temperature distribution allowed us to estimate the thermal sensitivity of the absorption coefficient in the THz range. This study showed that the THz sensor was sensitive enough to measure THz signal variations due to small temperature variations. The mean temperature may be determined along the thickness direction once the thermodependence of the transmission and reflection coefficients are known.
Sustainability of the Prevention of Passive Infant Smoking Within Well-Baby Clinics

This study assessed the antecedents of continued use of an education program to prevent passive smoking in infants. It consists of a booklet for parents and a manual for health professionals describing a five-step procedure for discussing passive smoking. Aquestionnairewas sent to 67 managers, 670 nurses, and 335 physiciansworking in well-baby clinics (response rate: 70%, 53%, 47% respectively). Questions concerned the completeness of use, level of institutionalization, and characteristics of the organization, the user, and the dissemination strategy. Seventy-one percent of nurses and42% of physiciansworked with the program. They foremost provided the first three steps of the five-step procedure. Physicians' completeness of usewas related to their perceived responsibility in providing this education, and nurses' use was related to their perceived self-efficacy, responsibility, training attendance, participation in the adoption decision, and level of institutionalization. Diffusion efforts should focus on improving the completeness of use and level of institutionalization.
