A Sparse Aperture MIMO-SAR-Based UWB Imaging System for Concealed Weapon Detection

A high-resolution imaging system based on the combination of ultrawideband (UWB) transmission, multiple-input-multiple-output (MIMO) array, and synthetic aperture radar (SAR) is suggested and studied. Starting from the resolution requirements, spatial sampling criteria for nonmonochromatic waves are investigated. Exploring the decisive influence of the system's fractional bandwidth (instead of previously claimed aperture sparsity) on the imaging capabilities of sparse aperture arrays, a MIMO linear array is designed based on the principle of effective aperture. For the antenna array, an optimized UWB antenna is designed allowing for distortionless impulse radiation with more than 150% fractional bandwidth. By combining the digital beamforming in the MIMO array with the SAR in the orthogonal direction, a high-resolution 3-D volumetric imaging system with a significantly reduced number of antenna elements is proposed. The proposed imaging system is experimentally verified against the conventional 2-D SAR under different conditions, including a typical concealed-weapon-detection scenario. The imaging results confirm the correctness of the proposed system design and show a strong potential of the MIMO-SAR-based UWB system for security applications.
Mestrado Integrado em Psicologia

Social networks such as Facebook seem to constitute a broad social context that privileges interpersonal connections, influencing not only the emergence of romantic relationships, but also the maintenance of them. If, on the one hand, it seems to bring the couple's members together through easy and rapid communication, sharing of affections and interests, on the other, it can intensify the experience of jealousy, as well as, partner monitoring behaviors. Jealousy related to Facebook is a phenomenon still in understanding, however, it is known that for its explanation contribute variables of personal, relational and sociocultural nature. The main objective of the present study is to contribute to the clarification of these relationships by analyzing the associations between sex, the orientation of the attachment with the partner, the intensity of use of Facebook (FB) and satisfaction in the relationship. Additionally, it is proposed to test the moderating effect of satisfaction in the romantic relationship in the association between attachment and jealousy experience in FB. Finally, it analyzes the variation of the articulation model between these variables as a function of sex. The sample is made up of 542 young adults, of both sexes (75% of girls), who answered an online questionnaire.The results suggest that the anxiety towards the partner and the intensity of the use of FB have direct effects in all the dimensions of the jealousy, as opposed to the avoidance towards the partner that only had a direct effect in the cognitive dimension of the jealousy. It was also found an interaction effect between satisfaction in relationship and avoidance towards the partner in the behavioral dimension of jealousy, being that for high values of avoidance and low satisfaction in the relationship, higher values are registered in the behavioral dimension. The proposed conceptual model proved to be globally invariant for both sexes, with only significant differences between men and women in the effect of anxiety towards the partner in the emotional and behavioral dimensions and in the interaction effect between avoidance and satisfaction in the relationship in cognitive dimension of jealousy, these effects being significant only for women. Thus, these results suggest that variations vi in the values of anxiety, such as in the intensity of FB use, explain variations in the values of all dimensions of jealousy related to FB, and thus, the variables that best predict not only emotions, such as jealous behaviors and cognitions. Moreover, an effect of sex on the emotional dimension of jealousy suggests differences between men and women, with the latter indicating more jealous emotions than men. The results and implications for future investigations are discussed.
Desire and desire regulation

A good deal of people’s waking time is, more or less directly, spent thinking about and dealing with desire. There is no question that desires are often benign, functional, and evolutionary adaptive for the individual. However, there are cases where desire stands in conflict with important (selfregulatory) goals or (moral) values. Prime examples include the exsmoker who, upon seeing other people smoke, reexperiences a strong craving for a cigarette despite her intention to never smoke again, or two colleagues at work who cannot help feeling sexually attracted to each other despite the fact that one of them has made public vows of faith on the not-so-long-ago wedding day. And sometimes, much more trivially, the time or opportunity to fulfill a certain desire is just not “right,” such as when someone feels a strong need to pee on a long bus ride and, alas, the toilet is broken. There are both individual and societal reasons for why the capacity for desire regulation is such a highly important aspect of everyday functioning. The primary questions that we seek to answer in this chapter are: What is desire? When does it become problematic? How does desire regulation work? When and why can it go wrong? And how can it be improved? To approach issues of desire regulation, we will draw both on the literature of selfcontrol and emotion regulation. The selfcontrol literature is central because desires are driving forces that sometimes need to be held in check through inhibition or overriding. Selfcontrol research has yielded a wealth of insights on how such inhibitory processes may work and when they may be disturbed. More recently, the field has begun to scrutinize anticipatory, preventive strategies through which people actively set the stage for later selfcontrol successes (Fujita, 2011; C H A P T E R 3

Morusin inhibits glioblastoma stem cell growth in vitro and in vivo through stemness attenuation, adipocyte transdifferentiation, and apoptosis induction

Glioblastoma multiforme (GBM) cancer stem cells (GSCs) are responsible for the progression and recurrence of GBM after conventional therapy. Morusin possesses anti‐cancer activity in vitro. The purpose of this study is to confirm the growth inhibition effect of morusin on human GSCs growth in vitro and in vivo and to explore the possible mechanism of its activity. Human GSCs were enriched under nonadhesive culture system, and characterized through neurosphere formation, toluidine blue staining, immunofluorescence staining, Western blotting analysis of stemness markers of CD133, nestin, Sox2 and Oct4, and tumorigenecity in vivo; the growth inhibition effect of morusin on human GSCs in vitro and in vivo were tested by cell cytotoxicity, neurosphere formation inhibition, adipogenic differentiation, apoptosis induction, and tumor growth inhibition in vivo assays. The potential molecular mechanisms underlying the growth inhibition effect of morusin on GSCs in vitro and in vivo were investigated with Western blotting evaluation of stemness, adipogenic, and apoptotic proteins in morusin treated GSCs and tumor tissues. GSCs enriched under nonadhesive culture system possess stemness characterstics; Morusin inhibited GSCs growth in vitro and in vivo, it reduced stemness of GSCs, induced them adipocyte‐like transdifferention and apoptosis. Morusin has the potential to inhibit human GSCs growth in vitro and in vivo through stemness attenuation, adipocyte transdifferentiation, and apoptosis induction. © 2014 Wiley Periodicals, Inc.
Alcohol and Dating Risk Factors for Sexual Assault Among College Women

American societal norms frequently link alcohol, dating, and sexuality. This cross-sectional study examined the role of alcohol and dating risk factors for sexual assault among a representative sample of female students at a large urban university. Over half of the 1,160 women had experienced some form of sexual assault. Ninety-five percent of these assaults were committed by someone the woman knew and almost half of these assaults involved alcohol consumption by either the man, the woman, or both. Discriminant function analyses indicated that dating, sexual, and misperception experiences and alcohol consumption during these experiences predicted assault group status. Furthermore, alcohol consumption during consensual sex and sexual misperceptions were positively related to alcohol consumption during the sexual assault. The predictors of assault group status were similar for African American and Caucasian women. Theoretical implications are discussed and suggestions are made for combining alcohol and sexual assault prevention programming.
Anaplastic Thyroid Carcinoma: Current Treatments and Potential New Therapeutic Options with Emphasis on TfR1/CD71

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human cancers. Actually, ATC is refractory to conventional therapies, including surgery, chemotherapy, radiotherapy, and radioiodine (131I) therapy. Accordingly, genetic and molecular characterizations of ATC have been frequently and periodically reviewed in order to identify potential biological markers exploitable for target therapy. This review briefly focuses on main molecular events that characterize ATC and provides an update about preclinical studies. In addition, the overexpression of transferrin receptor 1 (TfR1/CD71) by neoplastic cells of ATC is emphasized in that it could represent a potential therapeutic target. In this regard, new therapeutic approaches based on the use of monoclonal or recombinant antibodies, or transferrin-gallium-TfR1/CD71 molecular complexes, or lastly small interfering RNAs (siRNAs) are proposed.
Interconnections between the Neuroendocrine Hypothalamus and the Central Autonomic System Geoffrey Harris Memorial Lecture, Kitakyushu, Japan, October 1998

Tract-tracing techniques in combination with immunohistochemistry and in situ hybridization were used in intact and operated rats (hypothalamic lesions, transections of neuronal pathways) to localize and characterize neuronal connections between the hypothalamus and autonomic centers. Viscerosensory and somatosensory signals which relay in the spinal cord and the medulla oblongata reach the hypothalamus through various catecholaminergic and noncatecholaminergic neuronal pathways. Vice versa, the hypothalamus influences autonomic activities through humoral and neurohumoral pathways. Descending hypothalamic efferents carry feedback signals to viscerosensory and brainstem catecholaminergic neurons and regulatory inputs to parasympathetic (dorsal vagal nucleus) and sympathetic (thoracolumbar intermediolateral cell column) preganglionic neurons. These fibers arise mainly from neurons of the paraventricular, arcuate, perifornical, and dorsomedial nuclei and the lateral hypothalamus. The major neuroanatomical observations are the following: (1) pathways between the hypothalamus and autonomic centers are bidirectional: the ascending and descending fibers may use the same avenues; (2) the descending axons are mainly peptidergic (CRF, vasopressin, oxytocin, somatostatin, enkephalin, POMC, and cANP), while the ascending fibers are both peptidergic (enkephalin, NPY, neurotensin, dynorphins) and catecholaminergic; (3) descending hypothalamic axons terminate directly on the sensory, preganglionic, and catecholaminergic neurons in the medulla and the spinal cord; (4) hypothalamic projections to the autonomic centers are always bilateral; (5) while medullary autonomic and catecholaminergic fibers innervate hypothalamic neurons directly, spinohypothalamic axons are relayed on neurons in the lateral hypothalamus.
Cooperative Self-Localization of Mobile Agents

This paper considers the problem of localizing multiple agents, e.g. unmanned aerial vehicles (UAVs), robots, etc., moving in two-dimensional space when the known data comprise 1) the inter-agent distances, and 2) the angle subtended at each agent by lines drawn from two landmarks at known positions. Later it is shown that this result has direct application in a different general robotic problem, viz. robot-to-robot relative pose determination (relative reference frame determination), using measured distances. The methods proposed are validated through simulations and experiments.
Coronary atherogenic risk factors in women.

Cardiovascular disease, primarily coronary heart disease (CHD), remains the most frequent cause of death in Western industrialized nations: nearly one in every two deaths are currently attributable to CHD. Since the 1980s, gender-specific trends have become apparent in these statistics: whereas coronary–vascular mortality has appreciably decreased among men, women have conversely experienced a continuous rise in rates of death from CHD. In 1998 in Germany, for example, there were 94 700 deaths from coronary vascular disease among women (225·3 per 100 000), but only 84 015 among men (210·1 per 100 000). One explanation of this trend may lie in the fact that modern medicine over the past 30 to 40 years has considered CHD a ‘male disease’, and that classical epidemiological studies have consequently concentrated primarily on men. Fortunately for men, this phenomenon, its associated preventive measures, and improved therapeutic approaches have signified a decrease in mortality among men. The contrary development among females may be attributed to two factors: that insights gained in research for men are not automatically applicable to women, and/or that women less often enjoy application of advances in possibilities for diagnosis and therapy resulting from these insights. Since the 1980s, moreover, changes have taken place in the risk factor profile in women and men. Although the overall prevalence of risk factors such as hypertension, overweight, and smoking remains greater for men, the total increase in such risk factors has in recent decades been greater among women to a pronounced degree. This development has become especially apparent in smoking, which has increased among young women in contrast to a decreasing trend among men.
Autistic children's understanding of seeing, knowing and believing

In this study we establish that autistic children have severe and specific difficulty with understanding mental states. Even with a mental age of 7 years, these children mostly fail in tasks which are normally passed around age 3 and 4. We confirm previous results on the poor understanding of false belief but also find that autistic children's grasp of the notion of limited knowledge is grossly delayed. We rule out various other explanations for these results and further show that the autistic child's performance is not limited by failure to understand the causal notion of seeing. Likewise, memory failure cannot be blamed. Language delay can be ruled out as a cause of failure since a group of children with specific language impairment, matched for verbal mental age, performed at ceiling. We propose that autistic children are specifically impaired in their meta-representational capacity and that this impedes their construction of a ‘theory of mind’.
Malnutrition in hospitalized children: prevalence, impact, and management.

PURPOSE Malnutrition in hospitalized children has been reported since the late 1970s. The prevalence of acute and chronic malnutrition was examined in hospitalized patients in a general pediatric unit, and the impact and management of malnutrition were assessed. METHODS The nutritional risk score (NRS) and nutritional status (NS) (weight, height, body mass index, and skinfold thickness) of children aged zero to 18 years were assessed upon hospital admission. Growth and energy intake were monitored every three days until discharge. RESULTS A total of 173 children (median age three years, 88 girls) participated; 79.8% had a moderate to severe NRS and 13.3% were acutely and/or chronically malnourished. A high NRS was associated with a longer hospital stay in children older than three years (P<0.05), while a poor NS (weight for height percentile) was correlated with prolonged hospitalization in children aged three years or younger (P<0.05). Although weight did not change during hospitalization, a decrease in skinfolds was documented (n=43, P<0.05). Patients with a high NRS had lower energy intake than those not at risk. However, children with abnormal NS received 92.5% of recommended energy intake. CONCLUSIONS This study suggests that all children admitted to hospital should have an evaluation of their NRS and NS, so that they can receive appropriate nutrition interventions provided by a multidisciplinary nutrition team.
Unfair Partisan Gerrymanders in Politics and Law: A Diagnostic Applied to Six Cases

Abstract We propose standards for detecting partisan gerrymandering as a finding of fact and for determining whether the factual finding is legally significant. The standard is grounded in the U.S. constitutional principle of equal voting rights and is easily manageable inasmuch as its prime analytical feature requires comparing a party's district median vote percentage to its district mean vote percentage. Equally important, the median-mean comparison serves as an effective indicator of whether gerrymandering is the cause of the inequitable treatment. We apply the standard to six alleged cases of gerrymandering of congressional districts and find three cases are not gerrymanders, three are gerrymanders, and one of the three gerrymanders crosses the threshold to legal significance.
Leveraging evaluation metric-related training criteria for speech summarization

Many of the existing machine-learning approaches to speech summarization cast important sentence selection as a two-class classification problem and have shown empirical success for a wide variety of summarization tasks. However, the imbalanced-data problem sometimes results in a trained speech summarizer with unsatisfactory performance. On the other hand, training the summarizer by improving the associated classification accuracy does not always lead to better summarization evaluation performance. In view of such phenomena, we hence investigate two different training criteria to alleviate the negative effects caused by them, as well as to boost the summarizer's performance. One is to learn the classification capability of a summarizer on the basis of the pair-wise ordering information of sentences in a training document according to a degree of importance. The other is to train the summarizer by directly maximizing the associated evaluation score. Experimental results on the broadcast news summarization task show that these two training criteria can give substantial improvements over the baseline SVM summarization system.
Physical outcome measurements via the Internet: Reliability at two Internet speeds

summary We have developed a software application to enable interactive rehabilitation via the Internet. The reliability of the telemedicine application was examined by comparing it with face-to-face assessment. The physical outcome measures assessed were knee range of motion, quadriceps muscle strength, limb girth and an assessment of gait. One therapist performed both in-person and Internet-based measurements of all outcome measures on 20 normal subjects. There was good agreement between the two techniques (the 95% limits of agreement included zero for all the variables studied). Internet assessments were conducted at two bandwidths: ISDN at 128 kbit/s and the telephone network at 17 kbit/s. Bandwidth had no significant influence on any of the measures. This study suggests that Internet-based physiotherapy interventions delivered to the home are suitable for further development.
Open Access Research Article Comparison of Primary Care Experiences among Adults in General Outpatient Clinics and Private General Practice Clinics in Hong Kong

Background: The main goal of Hong Kong's publicly-funded general outpatient clinics (GOPCs) is to provide primary medical services for the financially vulnerable. The objective of the current study was to compare the primary care experiences of GOPC users and the users of care provided by private general practitioners (GPs) in Hong Kong via a territory-wide telephone survey. Methods: One thousand adults in Hong Kong aged 18 and above were interviewed by a telephone survey. The modified Chinese translated Primary Care Assessment Tool was used to collect data on respondents' primary care experience. Results: Our results indicated that services provided by GOPC were more often used by female, older, poorer, chronically-ill and less educated population. GOPC participants were also more likely to have visited a specialist or used specialist services (69.7% vs. 52.0%; p < 0.001), although this difference in utilization of specialist services disappeared after adjusting for age (55.7% vs. 52.0%, p = 0.198). Analyses were also performed to asses the relationship between healthcare settings (GOPCs versus private GPs) and primary care quality. Private GP patients achieved higher overall PCAT scores largely due to better accessibility Conclusions: Our results showed that patients primarily receiving care from private GPs in Hong Kong reported better primary care experiences than those primarily receiving care from GOPCs. This was largely due to the greater accessibility and better interpersonal relationships offered by the private GPs. As most patients use both GOPCs and private GPs, their overall primary care experiences may not be as different as the findings of this study imply. Background Considerable evidence supports the important role of primary care in the prevention of illness and death, regardless of whether the care is characterized by the supply of primary care physicians, a relationship with a source of primary care, or the receipt of important features of primary care [1]. Good primary care, in contrast to specialist services, is also associated with a more equitable distribution of health within and across populations [2,3]. Overall, both individual and ecological studies have
