Compressive MUSIC: A Missing Link Between Compressive Sensing and Array Signal Processing

The multiple measurement vector (MMV) problem addresses the identification of unknown input vectors that share common sparse support. Even though MMV problems had been traditionally addressed within the context of sensor array signal processing, the recent trend is to apply compressive sensing (CS) due to its capability to estimate sparse support even with an insufficient number of snapshots, in which case classical array signal processing fails. However, CS guarantees the accurate recovery in a probabilistic manner, which often shows inferior performance in the regime where the traditional array signal processing approaches succeed. The apparent dichotomy between the {\em probabilistic} CS and {\em deterministic} sensor array signal processing have not been fully understood. The main contribution of the present article is a unified approach that unveils a {missing link} between CS and array signal processing. The new algorithm, which we call {\em compressive MUSIC}, identifies the parts of support using CS, after which the remaining supports are estimated using a novel generalized MUSIC criterion. Using a large system MMV model, we show that our compressive MUSIC requires a smaller number of sensor elements for accurate support recovery than the existing CS methods and can approach the optimal $l_0$-bound with finite number of snapshots.
Growth, Reproductive Performance, Carcass Characteristics and Meat Quality in F1 and F2 Progenies of Somatic Cell-Cloned Pigs

The objective of this study was to examine the health and meat production of cloned sows and their progenies in order to demonstrate the application of somatic cell cloning to the pig industry. This study compared the growth, reproductive performance, carcass characteristics and meat quality of Landrace cloned sows, F1 progenies and F2 progenies. We measured their body weight, growth rate and feed conversion and performed a pathological analysis of their anatomy to detect abnormalities. Three of the five cloned pigs were used for a growth test. Cloned pigs grew normally and had characteristics similar to those of the control purebred Landrace pigs. Two cloned gilts were bred with a Landrace boar and used for a progeny test. F1 progenies had characteristics similar to those of the controls. Two of the F1 progeny gilts were bred with a Duroc or Large White boar and used for the progeny test. F2 progenies grew normally. There were no biological differences in growth, carcass characteristics and amino acid composition among cloned sows, F1 progenies, F2 progenies and conventional pigs. The cloned sows and F1 progenies showed normal reproductive performance. No specific abnormalities were observed by pathological analysis, with the exception of periarteritis in the F1 progenies. All pigs had a normal karyotype. These results demonstrate that cloned female pigs and their progenies have similar growth, reproductive performance and carcass quality characteristics and that somatic cell cloning could be a useful technique for conserving superior pig breeds in conventional meat production.
A MIMO Double Resonant Controller Design for Nanopositioners

A design of a double resonant controller to enhance the high-speed nanopositioning performance of a piezoelectric tube scanner (PTS) is presented in this paper. The design of the controller is demonstrated using a multi-input multi-output framework for damping, tracking, and cross coupling control in the PTS. A reference model control technique is applied to design the controller. The controller proposed in this paper achieves a bandwidth near to the first resonance frequency of the PTS. The controller is robust against changes in the resonance frequency of the PTS due to load change on the scanner. Experimental results using open-loop, closed-loop, and the built-in AFM proportional integral controller are presented to show the effectiveness of the proposed controller.
Combining Location-Aware Mobile Phone Applications and Multimedia Messaging

The quickly emerging usage of multimedia messages offers a new approach for mobile collaboration between users and services by providing a mature and easily accessible technology. This article presents a model for combining multimedia messaging, location awareness of a mobile phone and phone applications, and presents a study of users' experiences when they receive the functionality by multimedia message. The results show that the visual information provided in MM messages was perceived to support orientation in the current location and it was considered important. The results also show that social acceptance of the location-aware multimedia message attached application functionality varies between different message categories, favoring user control and personal filtering. It is suggested that the distinct information elements to be considered carefully in technical implementation and in user interface design include sharing and access right management. Particular attention must be paid to designing a categorization system, which is required for successful information filtering and for user interface design. The categorization system must be either commonly agreed or highly customizable.
The insular formations of the dolphin brain: Quantitative cytoarchitectonic studies of the insular component of the limbic lobe

The large insula of the bottlenose dolphin consists of radial gyri arising, in fanlike fashion, from the transverse insular gyrus, and is covered completely by the frontal, parietal, and temporal opercula. On cytoarchitectonic grounds, the dolphin insula is divided into anterior, middle, and posterior sectors that may be the equivalent of the three similar sectors present in the primate insula. Rostrocaudally, these sectors become increasingly more homogeneous and less laminated. Within each sector progressive differentiation occurs in the direction of the circular sulcus. A transitional cortex, the peripaleocortex in the transverse insular gyrus, is interposed between the prepiriform and the periamygdalar cortex and the proisocortex of the insula proper. This peripaleocortex consists of outer and inner cellular strata separated by a hypocellular lamina dissecans. The outer cell stratum is continuous with layers II and III of the insular proisocortex; the more prominent inner stratum is continuous with proisocortical layers V and VI; the intervening lamina dissecans becomes partially filled, mostly with modified pyramidal cells of medium size that may constitute an incipient layer IV. A band of myelinated fibers corresponding to the external band of Baillarger is found within the lamina dissecans. The anterior insular sector is characterized by distinct lamination and a well‐defined, ribbonlike layer Va. In the middle sector, the cortex is internodense and lamination is less clear. The posterior sector is even less laminated and tends to be externodense. Within each sector, lamination becomes clearer in the direction of the circular sulcus. Furthermore, the rostrocaudal architectonic changes suggest a possible transition from a motor‐type to a sensory‐type cortex. Beyond the insula, the architecture of the opercular cortices reflect, in turn, the influences of the insular sectors.
A socio-cultural approach to higher education students' experiences with academic literacies

The focus of this thesis is an exploration of students' engagement with academic literacies. The study is based on interview data, visual material and objects brought to these interviews by five students on an Education Studies undergraduate degree course. Drawing from the theoretical frame of New Literacy Studies, academic literacies are broadly defined as socially situated literacy practices. The focus is on how and where ‘academic literacies’ happen and how these literacies interact with personal histories and students' broader socio-cultural experience. Three themes: journeying, identity and emotional concerns, have been identified. The themes highlight the complex, nuanced and socially-embedded nature of the participants’ academic lives. In particular, Bakhtin’s notion of chronotopes is drawn on to illuminate the patterning of experiences in time and space. The findings provide insights into students’ broader literacy practices moving beyond the current focus on academic writing within the academic literacies field.
Novel molecular defects of the δ‐aminolevulinate dehydratase gene in a patient with inherited acute hepatic porphyria

Cloning and expression of the defective gene for δ‐aminolevulinate dehydratase (ALAD) from the second of 2 German patients with ALAD deficiency porphyria (ADP), who had been originally reported by Doss et al. in 1979, were performed. Cloning of cDNAs for the defective ALAD were performed using Epstein‐Barr virus (EBV)‐transformed lymphoblastoid cells of the proband, and nucleotide sequences of cloned cDNA were determined. Two separate mutations of ALAD cDNA were identified in each ALAD allele. One was G457A, termed “H1,” resulting in V153M substitution, while the other was a deletion of 2 sequential bases at T818 and C819, termed “H2,” resulting in a frame shift with a premature stop codon at the amino acid position of 294. Using allele‐specific oligonucleotide hybridization, the mother of the proband was shown to have an H1 defect, while using genomic DNA analysis, the father was shown to have an H2 defect. Expression of H1 cDNA in Chinese hamster ovary cells produced an ALAD protein with only a partial activity (10.65% ± 1.80% of the normal), while H2 cDNA encoded no significant protein. These data thus demonstrate that the proband was associated with 2 novel molecular defects of the ALAD gene, 1 in each allele, and account for the extremely low ALAD activity in his erythrocytes.
As French as Anyone Else: Islam and the North African Second Generation in France

Amid growing Islamophobia throughout Europe, Muslims in France have been described as “ethnoracial outsiders” (Bleich 2006, 3–7) and framed as a cultural challenge to the identity of the French republic. Based on ethnographic research of 45 middle class adult children of North African, or Maghrébin, immigrants, I focus on the actual religious practices of this segment of the French Muslim population, the symbolic boundaries around those practices, and the relationship between how middle class, North African second-generation immigrants understand their marginalization within mainstream society and how they frame their religiosity to respond to this marginalization. How respondents frame their practices reveals their allegiance with the tenets of French Republicanism and laïcité as well as shows how Muslim religious practices are being accommodated to the French context. This religiosity is not a barrier to asserting a French identity. Individuals frame their religious practices in ways that suggest they see themselves as just as French as anyone else.
Endometrial Profile of Tamoxifen and Low-Dose Estradiol Combination Therapy

Purpose: Combination estrogen + progestin therapy has been associated with increased breast cancer risk in postmenopausal women. Selective estrogen receptor modulators (SERM) are potential alternatives to progestins, although the endometrial safety of estrogen + SERM co-therapies is not known. The goal of this study was to evaluate the endometrial profile of low-dose estradiol and the SERM tamoxifen alone and in combination. Experimental Design: Twenty-four postmenopausal female cynomolgus macaques were randomized by social group to receive placebo, low-dose micronized estradiol (E2; 0.25 mg/1,800 kcal), the SERM tamoxifen (Tam; 20 mg/1,800 kcal), or E2 + Tam for 4 months in a parallel-arm design. Results: Tamoxifen alone resulted in overlapping but distinct effects compared with E2. Both E2 and Tam increased uterine weight and endometrial thickness, whereas only E2 increased endometrial proliferation. Morphologic effects were similar for Tam and E2 + Tam, which both induced stromal fibrosis and cystic change. Tamoxifen inhibited E2-induced proliferation and expression of genes related to cell cycle progression while exhibiting mixed agonist and antagonist effects on gene markers of estrogen receptor activity. The gene expression profile for E2 + Tam was distinct from either E2 or Tam alone but dominated by the Tam effect for estrogen-regulated genes. Tam also attenuated E2 effects on both vaginal maturation and cervical epithelial height. Conclusions: These findings characterize a novel phenotype resulting from estrogen + SERM co-therapy. The predominance of Tam effects on endometrial proliferation, morphology, and transcriptional profiles suggests that endometrial risks for E2 + Tam may be similar to Tam alone.

The research paper examines determinants among dividend payout of non-financial firms listed on Nairobi Securities Exchange. The NSE has 50 listed non-financial companies as per NSE 2012 report. Purposive sampling technique was used anda sample of 30 non-financial companies for duration of five years from 2007 to 2011 was selected. Secondary data was collected from audited financial statements of companies from Nairobi Securities Exchange website and the websites of non-financial firms' . Dividend payout ratio was dependent variable while independent variables were profitability, Growth, current earnings, and liquidity. Size and business risk was taken as moderating variables. Descriptive statistics and multiple regressions were used. Return on equity current earnings and firms' growth activities were found to be positively correlated to dividend payout Business risk and size,both the two taken as moderating variables increase the precision of significant variables from 95% to 99% hence among major determinants of dividend payout.
The Application of Self Psychology to Therapeutic Camps

Abstract Camp programs provide children and adolescents with vital opportunities to grow and are recognized as effective social work interventions. Children and adolescents with learning disabilities (LD) are at risk to experience psychosocial difficulties, which may result in difficulty attending regular camps. Self psychology can increase our understanding of these children's camp experiences, because of its focus on the individual's subjectivity and interactions throughout the lifespan and in therapeutic relationships. This paper extends the application of self psychology to therapeutic summer camps with children who have learning disabilities, illustrated through examples. The paper concludes with practice principles.
Evolution of cuticular hydrocarbon diversity in ants

The cuticular hydrocarbons (CHCs) of ants provide important cues for nest‐mate and caste recognition. There is enormous diversity in the composition of these CHCs, but the manner in which this diversity has evolved is poorly understood. We gathered data on CHC profiles for 56 ant species, relating this information to their phylogeny. We deduced the mode of evolution of CHC profiles by reconstructing character evolution and then relating the number of changes in CHC components along each branch of the phylogeny to the length of the branch. There was a strong correlation between branch length and number of component changes, with fewer changes occurring on short branches. Our analysis thereby indicated a gradual mode of evolution. Different ant species tend to use specific CHC structural types that are exclusive of other structural types, indicating that species differences may be generated in part by switching particular biosynthetic pathways on or off in different lineages. We found limited, and contradictory, evidence for abiotic factors (temperature and rainfall) driving change in CHC profiles.
Mathematical modelling of the citric acid cycle for the analysis of glutamine isotopomers from cerebellar astrocytes incubated with [1(-13)C]glucose.

A mathematical model of the citric acid cycle devoted to the analysis of 13C-NMR data was developed for determining the relative flux of molecules through the anaplerotic versus oxidative pathways and the relative pyruvate carboxylase versus pyruvate dehydrogenase activities. Different variants of the model were considered depending on the reversibility of the conversion of fumarate into malate and oxaloacetate. The model also included the possibility of orientation-conserved transfer of the four-carbon citric acid cycle intermediates, leading to conversion of succinyl-CoA C1 into either malate C1 or C4. It was used to analyse NMR data from glutamine isotopomers produced by cerebellar astrocytes incubated with [1-13C]glucose. Partial cycling (39%) between oxaloacetate and fumarate was evident from the analysis. Application of the model to glutamate isotopomers from granule cells incubated with [1-13C]glucose [Martin, M. Portais, J.C. Labouesse. J., Canioni. P, & Merle, M. (1993) Eur. J. Biochem. 217, 617-625] indicated that total cycling of oxaloacetate into fumarate was, in this case, required to get the best fit. The results emphasized some important differences in carbon metabolism between cerebellar astrocytes and granule cells concerning the sources of carbon fuelling the citric acid cycle and the carbon fluxes on different pathways.
Massive MIMO: ten myths and one critical question

Wireless communications is one of the most successful technologies in modern years, given that an exponential growth rate in wireless traffic has been sustained for over a century (known as Cooper's law). This trend will certainly continue, driven by new innovative applications; for example, augmented reality and the Internet of Things. Massive MIMO has been identified as a key technology to handle orders of magnitude more data traffic. Despite the attention it is receiving from the communication community, we have personally witnessed that Massive MIMO is subject to several widespread misunderstandings, as epitomized by following (fictional) abstract: “The Massive MIMO technology uses a nearly infinite number of high-quality antennas at the base stations. By having at least an order of magnitude more antennas than active terminals, one can exploit asymptotic behaviors that some special kinds of wireless channels have. This technology looks great at first sight, but unfortunately the signal processing complexity is off the charts and the antenna arrays would be so huge that it can only be implemented in millimeter-wave bands. ” These statements are, in fact, completely false. In this overview article, we identify 10 myths and explain why they are not true. We also ask a question that is critical for the practical adoption of the technology and which will require intense future research activities to answer properly. We provide references to key technical papers that support our claims, while a further list of related overview and technical papers can be found at the Massive MIMO Info Point: http://massivemimo. eu.
Evaluation of the left ventricle longitudinal deformity using myocardial-tracking signals in severely obese adolescents

Abstract Background The global prevalence of obesity in school-age children and adolescents has increased in recent decades. Obesity modifies some aspects of the cardiovascular system in order to preserve the body homoeostasis. Echocardiography to study ventricular function plays an important role in the evaluation of pathological re-modelling associated with left ventricular dysfunction. The aim of this study was to evaluate the left ventricle function and structure with conventional echocardiography and to analyse the longitudinal deformity of the left ventricle using myocardial-tracking signals in a group of severely obese adolescents. Methods and results We carried out a descriptive cross-sectional study. We describe the evaluation of the left ventricle using conventional bi-dimensional echocardiography and the myocardial-tracking signals in severely obese adolescents. There were 34 severely obese adolescents included in our study; 52% had a left ventricular ejection fraction<55%, the left ventricular end-diastolic diameter was increased in 70.5% of patients, and 32.3% had an increase in left ventricular mass. On average, 78.9% had abnormal values of left ventricle longitudinal deformations. The number of segments affected per patient was, on average, 5.8, with the anterior apical segment being the most commonly affected. There was a decrease in global longitudinal deformity in 79.4% of the cases. Conclusion More than half of this group of asymptomatic severely obese adolescents showed abnormalities in left ventricular structure and function evaluated using traditional echocardiographic methods, but 100% of the cases showed abnormalities in longitudinal deformation in at least one of the 17 left ventricle segments evaluated using myocardial-tracking signals.
The Metamorphosis to Test Validation

This article ]provides a history of test validation from the infancy of educational and psychological testing until the present, with emphasis on changes in our profession's conceptualization of test validation. This history indicates that test validation has increasingly taken on the meaning originally attached to construct validation. From the perspective of construct validation, the integration of psychological theory and research on one hand and psychometrics on the other is important for progress in both. Traditional content validation is also distinguished from test validation. Similarly, traditional criterion-related validation is shown as information for both decision makers and test validators rather than conclusive evidence of validity, as typically conceived. Other psychometric principles such as item analysis, reliability assessment and norms, are likewise shown to be relevant to test validation. Advances in psychometrics and statistical methodology as they affect test validation are briefly a.
Matrix Coherence and the Nystrom Method

The Nystrom method is an efficient technique used to speed up large-scale learning applications by generating low-rank approximations. Crucial to the performance of this technique is the assumption that a matrix can be well approximated by working exclusively with a subset of its columns. In this work we relate this assumption to the concept of matrix coherence, connecting coherence to the performance of the Nystrom method. Making use of related work in the compressed sensing and the matrix completion literature, we derive novel coherence-based bounds for the Nystrom method in the low-rank setting. We then present empirical results that corroborate these theoretical bounds. Finally, we present more general empirical results for the full-rank setting that convincingly demonstrate the ability of matrix coherence to measure the degree to which information can be extracted from a subset of columns.
