Automatic pixel-shift detection and restoration in videos

A common form of serious defect in video is pixel-shift. It is caused by the consecutive pixels loss introduced by video transmission systems. Pixel-shift means a large amount of pixel shifts one by one due to a small quantity of image data loss. The damaged region in affected frame is usually large, and thus the visual effect is often very disturbing. So far there is no method of automatically treating pixel-shift. This paper focuses on a difficult issue to locate pixel-shift in videos. We propose an original algorithm of automatically detecting and restoring pixel-shift. Pixel-shift frames detection relies on spatio-temporal information and motion estimation. Accurate measure of pixels shift is best achieved based on the analysis of temporal-frequency information. Restoration is accomplished by reversing the pixels shift and spatio-temporal interpolation. Experimental results show that our completely automatic algorithm can achieve very good performances.
TIME-DOMAIN POLARIZATION-SENSITIVE OPTICAL COHERENCE TOMOGRAPHY IN SOFT BIOLOGICAL TISSUE

Time-Domain Polarization-Sensitive Optical Coherence Tomography in Soft Biological Tissue. (August 2008) Milos Todorovic, B.S., University of Belgrade; M.S., Texas A&M University Co-Chairs of Advisory Committee, Dr. Lihong V. Wang Dr. Gerard L. Cote A new, high-speed, fiber-based Mueller-matrix optical coherence tomography system with continuous source-polarization modulation is presented. For in vivo experimentation, the sample arm optics are integrated into a hand-held probe. The system’s parameters were verified through imaging standard optical elements. A unique feature of polarization-sensitive Mueller optical coherence tomography is that by measuring Jones or Mueller matrices, it can reveal the complete polarization properties of biological samples, even in the presence of diattenuation. Presented here for the first time are mapped local polarization properties of biological samples obtained by using polar decomposition in combination with least-squares fitting to differentiate measured integrated Jones matrices with respect to depth. In addition, a new concept of dual attenuation coefficients to characterize diattenuation per unit infinitesimal length in tissues is introduced. The algorithm was experimentally verified using measurements of a section of porcine tendon and the septum of a rat heart.
Palmprint Recognition by using ModifiedLOCAL BINARY PATTERN

In This paper presents a efficient texture based recognition on multi scale local binary pattern (LBP) texture features . It’s a simple and fast for implementation, To extract useful representative features, “uniform” LBP was proposed and its effectiveness has been evaluated. However, all “non-uniform” patterns are grouped into one pattern, so a lot of useful information is lost. In this study, propose to build a modified multiscale LBP histogram for a palmprint image. The palmprint image is divided into several regions from which the LBP feature distributions are extracted and concatenated into an enhanced feature vector to be used as a image descriptor. The useful information of “non-uniform” patterns at large scale is dug out from its counterpart of small scale; the performance of the proposed method is that it can be fully utilize LBP features. Other applications and several extensions are also discussed
World oil reserves data: information quality assessment analysis

While high quality oil data can help oil companies and governments reduce risk of investments and increase profits, bad oil data can lead to economic losses. In this research, we propose a framework for assessing the information quality of world oil reserves data. The framework is applied by calculating the information quality ratings of relevant information sources. The information quality dimensions assessed in this framework include Data Decay, Data Integrity and Reputation, Data Coverage and Completeness, Degree of Compliance with Data Standards, Expertise of Data Source, and Degree to which Data was Vetted. Using the proposed framework, we assess the information qualities of some well-known sources of oil reserve data.
Electron Probe Microanalysis: A Review of the Past, Present, and Future

Abstract The 50th anniversary of the application of electron probe microanalysis (EPMA) to the Earth Sciences provides an opportunity for an assessment of the state-of-the-art of the technique. Stemming from the introduction of the first automated instruments, the latest developments of EPMA and some typical applications are reviewed with an eye to the future. The most noticeable recent technical achievements such as the field-emission electron gun, the latest generation of energy and wavelength dispersive spectrometers, and the development of analytical methods based on new sets of first principle data obtained by the use of sophisticated computer codes, allow for the extension of the method to the analysis of trace elements, ultra-light elements (down to Li), small particles, and thin films, with a high degree of accuracy and precision and within a considerably reduced volume of interaction. A number of working examples and a thorough list of references provide the reader with a working knowledge of the capabilities and limitations of EPMA today.
Clinical information extraction using small data: An active learning approach based on sequence representations and word embeddings

This article demonstrates the benefits of using sequence representations based on word embeddings to inform the seed selection and sample selection processes in an active learning pipeline for clinical information extraction. Seed selection refers to choosing an initial sample set to label to form an initial learning model. Sample selection refers to selecting informative samples to update the model at each iteration of the active learning process. Compared to supervised machine learning approaches, active learning offers the opportunity to build statistical classifiers with a reduced amount of training samples that require manual annotation. Reducing the manual annotation effort can support automating the clinical information extraction process. This is particularly beneficial in the clinical domain, where manual annotation is a time‐consuming and costly task, as it requires extensive labor from clinical experts. Our empirical findings demonstrate that (a) using sequence representations along with the length of sequence for seed selection shows potential towards more effective initial models, and (b) using sequence representations for sample selection leads to significantly lower manual annotation efforts, with up to 3% and 6% fewer tokens and concepts requiring annotation, respectively, compared to state‐of‐the‐art query strategies.
Patterns of Family Health History Communication Among Older African American Adults

This qualitative study examined patterns of communication regarding family health history among older African American adults. The authors conducted 5 focus groups and 6 semi-structured interviews with African Americans aged 60 years and older (N = 28). The authors identified 4 distinct patterns of family health history communication: noncommunication, open communication, selective communication (communication restricted to certain people or topics), and one-way communication (communication not reciprocated by younger family members). In general, participants favored open family health history communication, often resulting from desires to change patterns of noncommunication in previous generations regarding personal and family health history. Some participants indicated that they were selective about what and with whom they shared health information in order to protect their privacy and not worry others. Others described family health history communication as one-way or unreciprocated by younger family members who appeared uninterested or unwilling to share personal and family health information. The communication patterns that the authors identified are consistent with communication privacy management theory and with findings from studies focused on genetic testing results for hereditary conditions, suggesting that individuals are consistent in their communication of health and genetic risk information. Findings may guide the development of health message strategies for African Americans to increase family health history communication.
Human immune interferon gene is located on chromosome 12

A cDNA clone for human immune interferon (IFN-gamma) gene sequences, plasmid p69, was used to chromosomally map the IFN-gamma gene by detecting human IFN-gamma gene sequences in DNA isolated from human- rodent somatic cell hybrids. We were able to map the IFN-gamma gene by correlating the human chromosomes present in these hybrids with the human specific 8.8 and 2.0 kilobase pair fragments produced by EcoRI digestion of genomic DNA. Southern blot analysis of 37 hybrid cell lines indicated that the gene for IFN-gamma was on human chromosome 12. A hybrid containing a portion of chromosome 12 localized the IFN-gamma gene to the p1205 leads to qter region.
Tissue‐specific regulation of ACE/ACE2 and AT1/AT2 receptor gene expression by oestrogen in apolipoprotein E/oestrogen receptor‐α knock‐out mice

Angiotensin‐converting enzyme (ACE) and ACE2 and the AT1 and AT2 receptors are pivotal points of regulation in the renin–angiotensin system. ACE and ACE2 are key enzymes in the formation and degradation of angiotensin II (Ang II) and angiotensin‐(1–7)(Ang‐(1–7)). Ang II acts at either the AT1 or the AT2 receptor to mediate opposing actions of vasoconstriction or vasodilatation respectively. While it is known that oestrogen acts to downregulate ACE and the AT1 receptor, its regulation of ACE2 and the AT2 receptor and the involvement of a specific oestrogen receptor subtype are unknown. To investigate the role of oestrogen receptor‐α (ERα) in the regulation by oestrogen of ACE/ACE2 and AT1/AT2 mRNAs in lung and kidney, ovariectomized female mice lacking apolipoprotein E (ee) with the ERα (AAee) or without the ERα (ααee) were treated with 17β‐oestradiol (6 μg day−1) or placebo for 3 months. ACE, ACE2, AT1 receptor and AT2 receptor mRNAs were measured using reverse transcriptase, real‐time polymerase chain reaction. In the kidney, 17β‐oestradiol showed 1.7‐fold downregulation of ACE mRNA in AAee mice, with 2.1‐fold upregulation of ACE mRNA in ααee mice. 17β‐Oestradiol showed 1.5‐ and 1.8‐fold downregulation of ACE2 and AT1 receptor mRNA in AAee mice; this regulation was lost in ααee mice. 17β‐Oestradiol showed marked (81‐fold) upregulation of the AT2 receptor mRNA in AAee mice. In the lung, 17β‐oestradiol treatment had no effect on AT1 receptor mRNA in AAee mice, but resulted in a 1.5‐fold decreased regulation of AT1 mRNA in ααee mice. There was no significant interaction of oestrogen with ERα in the lung for ACE, ACE2 and AT2 receptor genes. These studies reveal tissue‐specific regulation by 17β‐oestradiol of ACE/ACE2 and AT1/AT2 receptor genes, with the ERα receptor being primarily responsible for the regulation of kidney ACE2, AT1 receptor and AT2 receptor genes.
Physical activity and perceptions of stress during the menopause transition: A longitudinal study

The transition to menopause is a critical period of significant biopsychosocial change. The purpose of this study was to examine the influence of the transition to menopause and volume of physical activity on levels of perceived stress over five years in 102 healthy middle-aged women. Questionnaire and accelerometer data were analyzed using linear mixed models. Adjusting for age and body mass index, there were no significant effects of menopause status or time on perceived stress. Independent of menopause status, minutes per week of vigorous activity was associated with lower perceived stress in years 1 and 2 of the study.
Synthesis of unsaturated fatty acids in chick embryo liver.

Oxidation, synthesis, and desaturation of fatty acids were assessed in chick embryos and embryonic liver. No differences in the oxidation of palmitate-1-14C and oleate-1-14C by intact embryos and embryo-liver homogenates were found. De novo fatty acid synthesis and microsomal elongation of fatty acids were detected in embryo-liver homogenates, but the activities were low as compared with chick liver. The specific activities of the mitochondrial system of fatty acid elongation were similar in embryo and chick liver. Stimulation of the desaturation of stearic acid was achieved by the substitution of glucose for fatty acids in the culture medium and abolished by the addition of cyclopropene fatty acids to the medium. The hypothesis is advanced that in chick embryos, the rate of desaturation of fatty acids synthesized de novo is less than that of postembryonic liver, and that as a consequence, the liver of embryos cannot maintain the proportion of unsaturated to saturated fatty acids found in yolk.
Failure patterns in patients with esophageal cancer treated with definitive chemoradiation

Local failure after definitive chemoradiation therapy for unresectable esophageal cancer remains problematic. Little is known about the failure pattern based on modern‐day radiation treatment volumes. We hypothesized that most local failures would be within the gross tumor volume (GTV), where the bulk of the tumor burden resides.
Tibolone: the way to beat many a postmenopausal ailments

Objective: The effects of tibolone on climacteric symptoms, osteoporosis, cardiovascular disease, breasts and the endometrium are summarised, and its role in clinical practice is reviewed in this article. Background: Tibolone has tissue-specific effects on receptors and enzymes that influence the synthesis and metabolism of endogenous sexual steroid hormones. Methods: This evaluation was based on the findings from several randomised studies, which addressed the basic and clinical research on tibolone. Results/conclusion: Clinical trials prove that tibolone is effective in the treatment of the menopausal symptoms and for the postponement and calming of symptoms accompanying age-related diseases. The findings of basic researchers that tibolone affects the metabolism of every cell, including malignant cells, opened a door to a whole new domain of research that has a promising future.
Dual association of a TRKA polymorphism with schizophrenia

Objective An interaction between predisposing genes and environmental stressors is thought to underlie the neurodevelopmental disorder schizophrenia. In a targeted gene screening, we previously found that the minor allele of the single nucleotide polymorphism (SNP) rs6336 in the neurotrophic tyrosine kinase receptor 1 (NTRK1/TRKA) gene is associated with schizophrenia as a risk factor. Methods We genotyped the TRKA SNP in a total of eight independent Caucasian schizophrenia case–control groups. Result Remarkably, although in five of the groups a higher frequency of the risk allele was indeed found in the patients compared with the controls, in the three other groups the SNP acted as a protective factor. Conclusion An intriguing possibility is that this dual character of the TRKA SNP is caused by its interaction with endophenotypic and/or epistatic factors.
Event‐Recorder Monitoring in the Diagnosis of Atrial Fibrillation in Symptomatic Patients: Subanalysis of the SOPAT Trial

In the SOPAT (suppression of paroxysmal atrial tachyarrhythmias) trial, a high number of asymptomatic atrial fibrillation (AF) episodes were registered in patients with symptomatic AF. This subanalysis was performed to answer three questions: (1) Does antiarrhythmic therapy influence the ratio of symptomatic to asymptomatic AF? (2) Are symptoms during AF dependent on the heart rate (HR)? (3) Do symptoms correlate with an episode of AF? Within 60 months 1,033 patients with symptomatic AF were randomized to either quinidine plus verapamil (Q+V) 480/240 mg/day, Q+V 320/160 mg/day, sotalol 320 mg/day, or placebo, and followed up by daily and symptom‐triggered ECG event recording. Over 188,634 ECGs were analyzed (87% SR, 7% AF). Symptoms were reported in only 46% of AF‐ECGs. Quinidine plus verapamil reduced the ratio of symptomatic to asymptomatic AF, whereas sotalol had no effect (median [%] (25/75% quartile): Q+V 480/240: 33 (0/79), Q+V 320/160: 45 (1/82), sotalol: 56 (7/93), placebo: 63 (8/92)). The HR during AF directly correlates with the occurrence of symptoms (P < 0.001) and was significantly lower during asymptomatic AF in all groups (mean ± SD: sympt.: 113 ± 27/minute, asympt.: 103 ± 27/minute, P < 0.001). Both antiarrhythmics reduced the mean HR compared to placebo (P < 0.001). Analyzing all symptom‐triggered ECGs, AF was diagnosed in only 37%, whereas the majority were SR. Taken together, in contrast to sotalol, Q+V reduces the ratio of symptomatic to asymptomatic AF compared with placebo, at least in part by decreasing the heart rate. Furthermore, patients' symptoms are not a reliable surrogate parameter for the prevalence of AF.
Marital/cohabitation status and history in relation to sleep in midlife women.

STUDY OBJECTIVES To examine whether current and/or history of marital/cohabitation status are associated with sleep, independent of demographic and general health risk factors. DESIGN Longitudinal, observational study of women, with sleep measured via multi-night in-home polysomnography and up to 35 nights of actigraphy. SETTING Participants' homes. PARTICIPANTS Caucasian (n = 170), African American (n = 138), and Chinese women (n = 59); mean age 51 years. INTERVENTIONS None. MEASUREMENTS Sleep quality was assessed via questionnaire. Sleep duration, continuity, and architecture were calculated using in-home polysomnography (PSG). Sleep continuity was also assessed by actigraphy. Categories of marital/cohabiting status or changes in status were inclusive of women who were legally married or living as married as well as transitions into or out of those partnership categories. RESULTS Partnered (married or cohabiting) women at the time of the sleep study had better sleep quality and PSG and actigraphy-assessed sleep continuity than unpartnered women; however, with covariate adjustment, most of these associations became non-significant. Analyses of women's relationship histories over the 6-8 years prior to the sleep study showed advantages in sleep for women who were consistently partnered versus women who were unpartnered throughout this interval, or those who had lost or gained a partner over that time course. These results persisted after adjusting for potential confounders. CONCLUSIONS The stable presence of a partner is an independent correlate of better sleep quality and continuity in women.
High-Selectivity Tunable Planar Combline Filter With Source/Load-Multiresonator Coupling

A tunable planar combline filter exhibiting multiple transmission zeros is reported in this letter. By introducing two new coupled lines, the source/load-multiresonator coupling phenomenon is obtained without using additional combline resonators. The transmission zero locations can be adjusted by means of the length of these coupled lines to improve the upper stopband rejection. Moreover, all of these transmission zeros can be tuned at the same time as the passband without distorting the filtering-response shape. Parasitic coupling effects of the proposed filter topology and guidelines for their compensation are also discussed. The described combline filter is experimentally validated with the design and manufacture of a three-stage electronically-tunable prototype with five transmission zeros.

Intranigral Transplants of Fetal Ventral Mesencephalic Tissue Attenuate D1-Agonist-Induced Rotational Behavior

Rats were given unilateral 6-hydroxydopamine lesions and tested 4 weeks later for rotational behavior elicited by either systemic or intranigral injections of dopamine agonists. Subsequently, transplants of fetal (E14) ventral mesencephalic (VM) or cortical tissue were implanted into the lesioned substantia nigra and allowed to develop and integrate within the parenchyma of the host midbrain for a 4-week period before rotational behavior was retested. In animals receiving transplants of fetal VM tissue, systemic injections of amphetamine (5.0 mg/kg,i.p.) or the D2-agonist, quinpirole (0.2 mg/kg, s.c.), elicited rotational behavior that was quantitatively similar to rotational behavior observed (1) before animals received transplants of fetal VM tissue or (2) in animals with midbrain transplants of fetal cortical tissue. Intranigral administration of quinpirole (10.0 microg) immobilized most animals and did not elicit rotational behavior in any animals regardless of treatment. Rotational behavior elicited by systemic administration of the D1-agonist, SKF 82958 (0.01 mg/kg, s.c.), was slightly attenuated by VM transplants placed into the midbrain. Rotational behavior elicited by intranigral injections of SKF 82958 (7.5 microg) was markedly reduced in animals with VM transplants. These data support the hypothesis that midbrain D1-receptors modulate the expression of dopamine agonist-induced rotational behavior.
Optimal Decision-making on Charging of Electric Vehicles

Large-scale development of electric vehicles (EVs) will have a significant impact on the power grid with their great demand for electric power consumption. It is necessary to design the optimal charging scheme for EVs. In this paper, we propose a centralized and a decentralized scheme of optimal decision-making on charging of EVs based on a dynamic pricing model. The objective of both schemes is to minimize the costs of EVs by establishing EV charging optimal schedules that fills the overnight load valley.The centralized scheme,whose objective is to minimize the total charging costs of all EVs, determines the charging schedules of EVs through solving a global optimization problem by the utility.The decentralized scheme is based on congestion game theory,under which the charging schedules are determined locally and directly by EVs to minimize their own costs. Detailed mathematical models and solution procedures are presented for both the centralized and decentralized schemes. Results show that both schemes have good performance on valley-filling.

A Measure of the Girth Histogram for Improved Girth-Conditioning Construction of LDPC Codes

In this letter, we present a general quantitative measure of the girth histogram of low-density parity-check (LDPC) codes with joint consideration of the degrees and local girths of symbol nodes. We then propose a further girth-conditioning algorithm to optimize such a measure during the construction of LDPC codes. We show by simulation results that the algorithm improves not only the performance of irregular codes at high signal-to-noise ratios (SNR) considerably, but also the rates of regular codes
