A step forward in multi-domain modeling of power LEDs

Besides their electrical properties the optical parameters of LEDs also depend on junction temperature. For this reason thermal characterization and thermal management plays important role in case of power LEDs, necessitating tools both for physical measurements and simulation. This paper deals with the combined electrical, thermal and optical characterization and multi-domain modeling of power LEDs. The major target is to provide with a model architecture and set of model equations the parameters of which can be all measured using a combined thermal and radiometric and photometric test setup completed with a spectrometer. Current and temperature dependent modeling of the light output of white LEDs is also addressed.
Parent Rated Symptoms of Inattention in Childhood Predict High School Academic Achievement Across Two Culturally and Diagnostically Diverse Samples

Objective: To investigate parent reports of childhood symptoms of inattention as a predictor of adolescent academic achievement, taking into account the impact of the child’s intellectual functioning, in two diagnostically and culturally diverse samples. Method: Samples: (a) an all-female sample in the U.S. predominated by youth with ADHD (Berkeley Girls with ADHD Longitudinal Study [BGALS], N = 202), and (b) a mixed-sex sample recruited from a Norwegian population-based sample (the Bergen Child Study [BCS], N = 93). Inattention and intellectual function were assessed via the same measures in the two samples; academic achievement scores during and beyond high school and demographic covariates were country-specific. Results: Childhood inattention predicted subsequent academic achievement in both samples, with a somewhat stronger effect in the BGALS sample, which included a large subgroup of children with ADHD. Intellectual function was another strong predictor, but the effect of early inattention remained statistically significant in both samples when intellectual function was covaried. Conclusion: The effect of early indicators of inattention on future academic success was robust across the two samples. These results support the use of remediation procedures broadly applied. Future longitudinal multicenter studies with pre-planned common inclusion criteria should be performed to increase our understanding of the importance of inattention in primary school children for concurrent and prospective functioning.
Finite element simulation of the insertion of guidewires during an EVAR procedure: example of a complex patient case, a first step toward patient‐specific parameterized models

Deformations of the vascular structure due to the insertion of tools during endovascular treatment of aneurysms of the abdominal aorta, unless properly anticipated during the preoperative planning phase, may be the source of intraoperative or postoperative complications. We propose here an explicit finite element simulation method which enables one to predict such deformations. This method is based on a mechanical model of the vascular structure which takes into account the nonlinear behavior of the arterial wall, the prestressing effect induced by the blood pressure and the mechanical support of the surrounding organs and structures. An analysis of the model sensitivity to the parameters used to represent this environment is done. This allows determining the parameters that have the largest influence on the quality of the prediction and also provides realistic values for each of them as no experimental data are available in the literature. Moreover, for the first time, the results are compared with 3D intraoperative data. This is done for a patient‐specific case with a complex anatomy in order to assess the feasibility of the method. Finally, the predictive capability of the simulation is evaluated on a group of nine patients. The error between the final simulated and intraoperatively measured tool positions was 2.1 mm after the calibration phase on one patient. It results in a 4.6 ± 2.5 mm in average error for the blind evaluation on nine patients. Copyright © 2015 John Wiley & Sons, Ltd.
Analysis of the Effect of Image Resolution on Automatic Face Gender Classification

This paper presents a thorough study into the influence of the image resolution on automatic face gender classification. The images involved range from extremely low resolutions (2 × 1 pixels) to full face sizes (329 × 264 pixels). A comprehensive comparison of the performances achieved by two classifiers using ten different image sizes is provided by means of two performance measures Correct Classification Rate (CCR) and Geometric Mean (GMean). Single- and cross-database experiments are designed over three well-known face datasets. A detailed statistical analysis of the results revealed that a face as small as 3 × 2 pixels carries some useful information for distinguishing between genders. However, in situations where higher resolution face images are available, moderately sized faces from 22 × 18 to 90 × 72 pixels are optimal for this task. Furthermore, the performance of the classifiers was robust to the changes in the image resolution (using medium to full sizes). Only when the image resolution was reduced to 8 × 6 pixels or smaller, the classification results were significantly affected.
Management of labour and delivery in congenitally corrected transposition of great arteries

A descriptive case report of the labour and delivery management of a 28‐year‐old woman who presented with congenitally corrected transposition of great arteries, dextrocardia, systemic ventricular dysfunction and junctional tachycardia. Patients with congenitally corrected transposition have a thin‐walled morphological right ventricle as the systemic circulatory pump. The stress of increased cardiac output can lead to congestive heart failure, systemic atrioventricular valve regurgitation and arrhythmias. We used minimally invasive continuous cardiac output monitoring, fluid balance optimization and good maternal pain control to prevent decompensation and achieve vaginal delivery with a good maternal and neonatal outcome.
Stochastic stabilization of complex networks with randomly topological structure

In this paper, the stabilization problem of complex networks is realized by a stochastically stabilizing controller, where the desired controller is added in terms of Brownian noise perturbation. Compared with the traditional methods on stabilizing controller, the stabilization scheme named to be stochastic pinning control in this paper is closely related to the Bernoulli variable and is only in the diffusion part. Moreover, the topological structure of the presented stochastic pinning controller is not constant but in terms of coupling matrix changing randomly, which is handled by the robust method. It is shown that the probability in addition to the switching between such different topological structures both play important roles in stochastic stabilization. Based on the obtained result, a more general case that the expectation of the Bernoulli variable having uncertainty is considered too. Finally, the correctness and effectiveness of the research results are verified by a numerical simulation.
Sequence analysis of Gardner‐Arnstein feline leukaemia virus envelope gene reveals common structural properties of mammalian retroviral envelope genes.

We have sequenced the envelope (env) gene and most of the adjacent 3′ long terminal repeat (LTR) of Gardner‐Arnstein feline leukaemia virus subtype B. The LTR of this virus contains, at corresponding positions, all signal sequence elements known from other retroviral LTRs. The deduced amino acid sequence of the longest open reading frame was compared with env polypeptide sequences of several murine leukaemia viruses. This allowed us to predict the positions of both p12/15env and gp70 polypeptides as well as a hydrophobic leader polypeptide. The env polypeptides of the different viruses show long stretches of homology and similar hydrophilicity profiles in the p12env region and in the carboxy‐terminal half of gp70 (constant region). The most extensive variations are confined to certain parts of the amino‐terminal half of gp70 (differential region). In this region, however, feline leukaemia virus and murine mink cell focus forming viruses are still closely related. A correspondingly spaced pattern of identical, short amino acid sequences appears in three different parts of the env polyprotein, suggesting its evolution from a primordial env‐related precursor by tandem duplications.
Wenyingzhuangia fucanilytica sp. nov., a sulfated fucan utilizing bacterium isolated from shallow coastal seawater.

A Gram-staining-negative, rod-shaped, strictly aerobic, non-flagellated, non-gliding and yellow-pigmented bacterial strain, designated as strain CZ1127T, capable of utilizing sulfated fucan, was isolated from shallow coastal seawater of Jiaozhou Bay, Qingdao, PR China. Its taxonomic position was investigated by a polyphasic approach. CZ1127T grew at 15-37 °C (optimum, 25 °C), pH 5.5-9.0 (optimum, pH 6.5-7.5) and in the presence of 0-4 % (w/v) NaCl [optimum, 0-3 % (w/v)]. CZ1127T contained MK-6 as the sole menaquinone, and iso-C15 : 0, iso-C17 : 0 3-OH, C16 : 1ω7c/C16 : 1ω6c and iso-C15 : 0 3-OH as its major fatty acids. The DNA G+C content of strain CZ1127T was 32.2 mol%. Phylogenetic analysis based on the 16S rRNA gene indicated that strain CZ1127T clustered with members of the genus Wenyingzhuangia and was closely related to Wenyingzhuangia marina CGMCC 1.12162T (97.4 % 16S rRNA gene sequence similarity) and Wenyingzhuangia gracilariae KCTC 42246T (96.1 %). The DNA-DNA relatedness between strain CZ1127T and W. marina CGMCC 1.12162T was 41.9±1.5 %. On the basis of the phenotypic, chemotaxonomic and phylogenetic data, CZ1127T represents a novel species of the genus Wenyingzhuangia, for which the name Wenyingzhuangia fucanilytica sp. nov. is proposed. The type strain is CZ1127T (=CCTCC AB 2015089T=KCTC 42864T).
Multilingual Sentiment Analysis: A New Approach to Measuring Conflict in Legislative Speeches

Comparative scholars of legislative politics continue to face the challenge of measuring a key theoretical concept: conflict at the level of legislative bills. We address this challenge with a multilingual sentiment-based approach and show that such a measure can effectively capture different types of parliamentary conflict. We also demonstrate that an automated translation of the dictionary yields valid results and therefore greatly facilitates comparative work on legislatures. Our applications show that a sentiment approach recovers government-opposition dynamics in various settings. The use of a simple, translatable sentiment dictionary opens up the possibility of studying legislative conflict in bill debates across languages and countries.
Well-Being Therapy: Conceptual and Technical Issues

Well-being therapy is a short-term, well-being-enhancing psychotherapeutic strategy. It is based on Carol D. Ryff’s multidimensional model of psychological well-being, encompassing environmental mastery, personal growth, purpose in life, autonomy, self-acceptance and positive relations with others. Its conceptual and technical issues are described. It may be applied as a relapse-preventive strategy in the residual phase of affective (mood and anxiety) disorders, as an additional ingredient of cognitive behavioral packages, in patients with affective disorders who failed to respond to standard pharmacological and psychotherapeutic treatments, in body image disorders and in psychosomatic medicine. The first validation studies appeared to be promising. The technique is in its preliminary stage of development and may undergo major changes in the next years. It is hoped it may herald a new trend of psychotherapy research and practice in the current symptom-oriented settings.
Patients’ evaluation of their psychiatric consultation after attempted suicide

Few studies have previously investigated patients’ evaluation of their psychiatric consultation after attempted suicide. The aim of the present study was to examine the patients’ view of their psychiatric consultation after a suicide attempt. Of a systematic sample of 114 suicide attempters in Helsinki, 73 subjects were referred to psychiatric consultation at an emergency room or department, and 53 of these evaluated the consultation received. Half of these suicide attempters considered their psychiatric consultation had occurred too soon after the attempt. Those whose prior attitude toward the consultation was indifferent had higher Hopelessness Scale (HS) and Beck Depression Inventory (BDI) scores than those who were positive. Psychiatric assessment should not take place before the patient has recovered from toxic effects caused by any overdose attempt. Suicide attempters with severe depression and hopelessness are likely to be those most indifferent to the prospect of psychiatric consultation. The presence of severe depression or hopelessness should not deter active evaluation and treatment.
BRCA1/2 Germline Mutations in Jewish Patients With Uterine Serous Carcinoma

Introduction: Whether and to what extent germline mutations in the BRCA1 and BRCA2 genes increase the risk for developing uterine serous carcinoma (USC) remain controversial. We assessed the rate of the 3 predominant BRCA1/2 mutations in Jewish patients with USC and the relevance of carrier status to clinicopathological features and survival. Methods: Jewish patients with histologically confirmed USC diagnosed between April 1997 and December 2007 were genotyped for the 3 predominant BRCA1 (185delAG and 5382insC) and BRCA2 (6174delT) mutations. Clinical characteristics were abstracted from the patients' medical records. The Kaplan-Meier method and log-rank tests were used for survival analyses. Results: Overall, 8 (25.8%) of 31 Jewish patients with USC who participated in the study were mutation carriers: 4 were BRCA2 (6174delT) carriers and 2 each carried the BRCA1 mutations (185delAG and 5382insC). The median ages of the carriers and the noncarriers were 66 and 74 years, respectively (P = 0.124). Four (50%) of the mutation carriers and 2 (8%) of the noncarriers had a family history of breast-ovarian cancer (P = 0.026). With a median follow-up of 76 months, the overall median survival time was 25 months. No significant differences in the median survival time, 2-year survival, or progression-free survival were noted between the mutation carriers and the noncarriers. Conclusions: The high rate of the predominant BRCA1/2 mutations in unselected Jewish USC patients, if confirmed by future studies, suggests that USC could be considered an expression of the hereditary breast-ovarian cancer syndrome.
Face detection on distorted images by using quality HOG features

Here, evaluate the abasement in execution of well known and effective face detector when human captured picture quality is corrupted by additive gaussian noise and blur. It is observed that, inside a specific scope of recognized picture quality, an adequate increase in picture quality can improve face detection performance. These results can be utilized to guide data transfer capacity which regards with face detection task. A new face detector based on QualHOG features is proposed for robust face detection that increases image indicative Histogram of Oriented Gradients (HOG) features with perceptual quality-aware spatial Natural Scene Statistics (NSS) features. The new detector provides significant improvement in tolerance to image distortion. To improve this research, new face database containing face and non-face patches from pictures by variety of common distortion types and levels were created. Here we used 347 faces and 1287 non-faces database.
Advanced Reflector Characterization with Ultrasonic Phased Arrays in NDE Applications

Ultrasonic arrays are increasingly widely used in nondestructive evaluation (NDE) due to their greater flexibility and potentially superior performance compared to conventional monolithic probes. The characterization of small defects remains a challenge for NDE and is of great importance for determining the impact of a defect on the integrity of a structure. In this paper, a technique for characterizing reflectors with subwavelength dimensions is described. This is achieved by post-processing the complete data set of time traces obtained from an ultrasonic array using two algorithms. The first algorithm is used to obtain information about reflector orientation and the second algorithm is used to distinguish between point-like reflectors that reflect uniformly in all directions and specular reflectors that have distinct orientations. Experimental results are presented using a commercial 64-element, 5-MHZ array on two aluminum test specimens that contain a number of machined slots and side-drilled holes. The results show that the orientation of 1-mm-long slots can be determined to within a few degrees and that the signals from 1-mm-long slots can be distinguished from that from a 1-mm-diameter circular hole. Techniques for quantifying both the orientation and the specularity of measured signals are presented and the effect of processing parameters on the accuracy of results is discussed.
Functional gain in hemorrhagic stroke patients is predicted by functional level and cognitive abilities measured at hospital admission.

BACKGROUND AND PURPOSE Few studies have addressed factors that contribute to functional recovery in people with hemorrhagic stroke. We assessed the value of using pre-training functional level and cognitive abilities measured at admission in order to predict functional gain in a sample of stroke patients. METHODS The Functional Independence Measure (FIM) was administered to 85 hemorrhagic stroke patients. Three multiple regression models were constructed using total gain in FIM scores, gain in scores in the cognitive domain of FIM, and gain in scores in the motor domain of FIM as outcome variables. Predictor variables were age; scores on the Digit Span Forward Test (DSF), Digit Span Backward Test (DSB), and Chinese Auditory Verbal Learning Test (CAVLT); and the FIM scores measured at admission. RESULTS All regression models were significant, Ps < 0.001, and each explained over 73% of the variance in the FIM gains. Age and admission FIM scores were both significant predictors in each of the three models. The DSB span score was a significant predictor of the total FIM and the cognitive FIM gains. The CAVLT recognition score was also a significant predictor of the cognitive FIM gain. CONCLUSIONS Functional improvement in patients with hemorrhagic stroke after in-patient rehabilitation was predicted by age, pre-training functional level, and cognitive abilities measured at admission.
An Innovative Process of Simultaneous Desulfurization and Denitrification by Thiobacillus denitrificans

Abstract Thiobacillus denitrificans, a species of autotrophic facultative anaerobic bacterium, was found to be capable of oxidizing sulfide into elemental sulfur when nitrate was adopted as its electron acceptor and carbon dioxide as its sole carbon source under anoxic conditions. In this way, sulfur was accumulated extracellularly and nitrate was converted into nitrogen gas. Based on these special physiological characteristics, an innovative process of simultaneous desulfurization and denitrification (SDD) was developed to obtain sulfur from sulfide. A strain of T. denitrificans, named D4, was isolated and used as sulfur producers in this study. The stoichiometric equations of SDD by T. denitrificans were also derived. The key factors affecting this process were investigated through continuous-flow and batch tests. The experimental results indicated that both the sulfide concentration and the ratio of S2−/NO3 − in the influent are key factors. Their suitable levels are suggested to be controlled less than 300 mg/L and 5/3–5/2, respectively, to achieve a high sulfur conversion degree.
Efficient wideband signal parameter estimation using a radon-ambiguity transform slice

A novel efficient technique based on a single slice Radon-ambiguity transform (RAT) for time-delay and time-scale estimation is proposed. The proposed approach combines the narrowband cross-ambiguity function (NBCAF), the wideband cross-ambiguity function (WBCAF), and a single slice RAT to estimate multiple target parameters in noisy environments. The square modulus of Gaussian-enveloped linear frequency modulated (GLFM) signals has high-energy centrality in the ambiguity plane. Its peaks in the NBCAF fall along nearly straight lines whose slopes depend on the Doppler rates of the moving targets. These lines could be effectively detected by computing the entire Radon transform of the NBCAF for all possible angles; however, it is a computationally intensive procedure. It is shown that without calculating the entire RAT, it is possible to estimate target parameters using only a single slice of the RAT, i.e., using an appropriate projection of the NBCAF. It is demonstrated that the proposed method can successfully separate overlapping targets efficiently. The efficiency is achieved due to fast Fourier transform (FFT)-bascd processing, use of a single slice of RAT, and the use of only one-dimensional (1-D) searches.
Twitter in Place Examining Seoul’s Gwanghwamun Plaza through Social Media Activism

Abstract In Korea, social networking sites are overwhelmingly utilized through smart phones; people tweet or update Facebook with their mobile devices. Like any social networking site, this means that people are making (and remaking) connections with each other, but it also means that people are connecting in complex ways to place. Even if geo-location is disabled, these social media still have this embodied dimension; they’re not just tweets, but tweets in a particular space and time. In Seoul, embodied practices of social media infuse spaces with diverse and networked meaning that interact (however weakly) with existing spatial systems. In this essay, I explore the diverse meaning of public space in Seoul through an analysis of Twitter traffic surrounding enormous protests in 2016 at Gwanghwamun Plaza calling for the resignation of President Park Geun-hye. People who protested against the President in Gwanghwamun Plaza were not only calling for her resignation, but they are also making strong claims to space that re-define the heterogeneous site as a space of protest. At the same time, they are not the only groups making claims on the plaza: conservative groups, merchants, commuters, tourists and various bots tweet other meanings through their interactions with the protest site, and these, too, add to the networked representation of Gwanghwamun Plaza. Ultimately, the paper suggests a theory of social media in urban settings which emphasizes complex interactions of space, representation, networked action, absence and presence.
