Kd-tree Based Nonuniform Simplification of 3D Point Cloud

For the over data density of point cloud that greatly affects the model reconstruction efficiency, a nonuniform simplification algorithm for point cloud with normal is presented. At first, kd-tree is used to represent the spatial topology relationships among the point cloud. According to the point density and expectative k-nearest neighbors, the radius of the bounding sphere is calculated to create the sphere centered at the point of the point cloud. Then, the local normal variance and the number of remained points of the neighbors are calculated according to the neighbors of the center point of the sphere, thus determining both their thresholds. The experimental results show that the proposed simplification approach has higher operation efficiency and can avoid holes.
ROBUST HUMAN FACE HIDING ENSURING PRIVACY

Nowadays, video surveillance of people must ensure privacy. In this paper, we propose a seamless solution to that problem by masking faces in video sequences, which keeps people anonymous. The system consists of two modules. First, an analysis module identifies and follows regions of interest (ROI's) where faces are detected. Second, the JPEG 2000 encoding module compresses the frames keeping the ROI’s in a separate data layer, so that the correct rendering of human faces can be restricted. The analysis module combines two complementary methods: face detection, to locate faces in the image, and tracking, to follow them seamlessly along the time. The fusion of these two methods increases robustness: once a face has already been detected in a frame, tracking may locate it in the consecutive frames, even when a face detection algorithm would not. In addition, detection of faces prevents tracking from loosing its targets. The encoding module downshifts the JPEG 2000 data corresponding to the identified ROI's to the lowest quality layer of the codestream. When the transmission bandwidth is limited, the human faces will then be decoded with a lower visual quality, up to invisibility when required. The proposed solution has been tested on different types of sequences. The results are presented in the paper.
Frame Semantics Evolutionary Model for Emotion Detection

Emotions play a significant role in identifying attitude, state, condition or mode of a particular circumstance. Textual data, in particular, involves emotional state and affective communication beside its informative contents. Emotion extraction from text has been potentially studied to stimulate and elicit articulation features. In this study, a machine learning emotion detection model is proposed for textual emotion recognition. A frame semantics approach is identified to extract knowledge from the text in an evolutionary process that improves the detection capabilities. Emotion detection process is controlled by a rule base; each of its entries is generated by pre-invoking event, action and resulting emotion state. Frame entities semantically collaborated to evaluate the frame emotion. Individual entities may arbitrary substituted by their synonyms or opposites if a candidate frame doesn’t match any of the knowledge set. The proposed model proves considerable capability of recognizing emotions by referencing their semantic relations. Results showed better detection accuracy for the proposed model compared with variety of emotion approaches including keyword spotting, knowledge-based ANN and supervised machine learning models. Experiments indicated encouraging results over both binary emotion and multiple labels classifiers.
Optimization of Phased Arrays Integrated with FSS and Feeding Elements based on Parametric Models

In this paper, we introduce a general framework to efficiently optimize phased array antennas integrated with Frequency Selective Surfaces (FSS) and feeding elements. The framework consists of two main parts: the first being parametric models that enable fast evaluation of the full-wave problem for a range of frequency, scan angle and geometry parameters. The second part consists of a number of optimization methods to generate an optimum set of geometry parameters by minimization of a penalty function. Results are shown for parametric models and the optimization of various examples.
Emergency Zone 3 Modification as a Local Response-Driven Protection Measure Against System Collapse

This paper proposes a protection scheme that applies two supervisory zones on each distance relay in the transmission system and timers in order to avoid undesirable Zone 3 operations under voltage-stressed system conditions. The speed at which the apparent impedance trajectory crosses the two supervisory zones is measured by the relay in order to determine the rate of change of the apparent impedance. Zone 3 modifications based on the normalized rate of change of the apparent impedance are applied: 1) Zone 3 operating area is reduced by using circle or straight line blinders when the instability is clearly recognized; 2) Zone 3 is blocked when there is no enough time to identify the cause of the apparent impedance transition; and 3) no measure is applied for a fault or a power swing. Simulations performed in a test power system show the effectiveness of this method in mitigating system blackouts due to cascaded outages.

Application of a new explicit‐rate ABR traffic controller

In broadband integrated communication systems, the classical method of max–min fair‐rate allocation for traffic control does not support the weighted‐rate guarantee. The weighted‐rate guarantee is necessary for available‐bit rate (ABR) service models. This fact motivates that the weighted max–min (WMM) fair‐rate allocation for the ABR traffic is widely studied. However, the combination of close‐loop feedback control with WMM algorithm has not appeared in the previous research. In this paper, a practical WMM fair‐rate allocation model is proposed. This scheduling scheme combines and integrates the congestion avoidance using proportional control (CAPC) and the weighted max–min fair‐rate allocation. This model is designed to achieve higher utilization and also bounded delay for ABR traffic flow control. In the system under analysis, the performance of this new weighted traffic scheduler is evaluated. The system presented in this paper is also compared with WMM and CAPC methods.

Disparities in Health-Related Internet Use Among African American Men, 2010

Given the benefits of health-related Internet use, we examined whether sociodemographic, medical, and access-related factors predicted this outcome among African American men, a population burdened with health disparities. African American men (n = 329) completed an anonymous survey at a community health fair in 2010; logistic regression was used to identify predictors. Only education (having attended some college or more) predicted health-related Internet use (P < .001). African American men may vary in how they prefer to receive health information; those with less education may need support to engage effectively with health-related Internet use.

Are Web services finally ready to deliver?

Web services, in brief, are a framework of software technologies designed to support interoperable machine-to-machine interaction over a network. Companies on different systems can use Web services to exchange information online with business partners, customers, and suppliers. Various standards organizations and industry consortia are developing Web services specifications without a unifying authority. Organizations such as the World Wide Web Consortium (W3C), the Organization for the Advancement of Structured Information Standards (OASIS), the Liberty Alliance Project, and the Web Services Interoperability Organization (WS-I) have developed or reviewed numerous standards. A primary goal of Web services is to unlock a new generation of e-commerce applications.
A 5-GHz fractional-N phase-locked loop with spur reduction technique in 0.13-μm CMOS

This work proposes a fractional phase error compensation approach for a classical fractional-N phase-locked loop (PLL) to reduce fractional spurs. The proposed corresponding-phase compensation technique incorporates a divider array and an auxiliary charge pump pair to overcome the fractional phase error. The main advantage of the proposed fractional-N PLL is that it only uses a constant compensation ratio when being a desired divide ratio. This PLL is fabricated in the TSMC 0. 13μm CMOS process. The total power consumption is about 17 mW. The measured results show that, with the proposed corresponding-phase compensation technique, the fractional spurs are reduced under classical fractional-N PLL.
User Recognition From Social Behavior in Computer-Mediated Social Context

Social interactions are integral part of human behavior. Although social interactions are likely to possess unique behavioral patterns, their significance for automated user recognition has been noted in the scientific community only recently. This paper demonstrated that it is possible to generate a set of unique features, called social behavioral (SB) features, from the social interactions of individuals’ via an online social network (OSN). Specifically, this research identified a set of SB features from the online social interactions of 241 Twitter users and proposed a framework to utilize these features for an automated user recognition. Extensive experimentation demonstrated high recognition performance as well as distinctiveness of the proposed SB features. The most striking finding was that only ten recent tweets are enough to recognize 58% of users in our database at rank-1. The rank-1 recognition rate dramatically increased to 93% when 60 tweets were used as a probe set. Experimental results also demonstrated the stability of the proposed SB feature set over time and ability to recognize both frequent and nonfrequent OSN users. This confirms that human social behavior expressed through an OSN can provide a unique insight into user behavior recognition.
Magnetic induction tomography: hardware for multi-frequency measurements in biological tissues

Magnetic induction tomography (MIT) is a contactless method for mapping the electrical conductivity of tissue. MIT is based on the perturbation of an alternating magnetic field by a conducting object. The perturbation is detected by a voltage change in a receiver coil. At physiologically interesting frequencies (10 kHz-10 MHz) and conductivities (<2 S m-1) the lower limit for the relative voltage change (signal/carrier ratio = SCR) to be resolved is 10-7-10-10. A new MIT hardware has been developed consisting of a coil system with planar gradiometers and a high-resolution phase detector (PD). The gradiometer together with the PD resolves an SCR of 2.5×10-5 (SNR = 20 dB at 150 kHz, acquisition speed: 100 ms). The system operates between 20 and 370 kHz with the possibility of extending the range up to 1 MHz. The feasibility of measuring conductivity spectra in the β-dispersion range of biological tissues is experimentally demonstrated. An improvement of the resolution towards SCR = 10-7 with an SNR of ⩾20 dB at frequencies >100 kHz is possible. On-line spectroscopy of tissue conductivity with low spatial resolution appears feasible, thus enabling applications such as non-invasive monitoring of brain oedema.
Integrated Systems and Technologies A Search for Novel Cancer / Testis Antigens in Lung Cancer Identi fi es VCX / Y Genes , Expanding the Repertoire of Potential Immunotherapeutic Targets

Cancer/testis (CT) antigens are potential immunotherapeutic targets in cancer. However, the expression of particular antigens is limited to a subset of tumors of a given type. Thus, there is a need to identify antigens with complementary expression patterns for effective therapeutic intervention. In this study, we searched for genes that were distinctly expressed at a higher level in lung tumor tissue and the testes compared with other nontumor tissues and identified members of the VCX/Y gene family as novel CT antigens. VCX3A, a member of the VCX/Y gene family, was expressed at the protein level in approximately 20% of lung adenocarcinomas and 35% of squamous cell carcinomas, but not expressed in normal lung tissues. Among CT antigens with concordant mRNA and protein expression levels, four CT antigens, XAGE1, VCX, IL13RA2, and SYCE1, were expressed, alone or in combination, in about 80% of lung adenocarcinoma tumors. The CT antigen VCX/Y gene family broadens the spectrum of CT antigens expressed in lung adenocarcinomas for clinical applications. Cancer Res; 74(17); 4694–705. 2014 AACR.
Insect sting-inflicted systemic reactions: attitudes of patients with insect venom allergy regarding after-sting behavior and proper administration of epinephrine.

BACKGROUND Patients with insect venom allergy are at higher risk for development of a recurrent systemic reaction after re-sting. This risk significantly decreases with venom immunotherapy. Patients with insect venom allergy should be able to distinguish a life-threatening systemic reaction from all other various reactions after an insect sting. Accidental epinephrine injection by EpiPen has been reported in the past. Therefore patients with venom allergy should also be well trained in self-administration of their epinephrine when needed. OBJECTIVE Our objective was to assess patients' attitudes regarding after-sting behavior and their capability to correctly self-administer the epinephrine autoinjector. METHODS All patients with venom allergy attending our allergy unit either before commencement of or during venom immunotherapy answered a questionnaire addressing various aspects of their intended after-sting behavior. Using an EpiPen trainer device, patients' performance of EpiPen self-administration was evaluated. RESULTS Ninety-six patients participated in the study. Seventy-six of them were equipped with an EpiPen device. Less than 30% of these patients carried it at all times. After re-sting, 50 (54%) patients planned to wait for the development of other symptoms before taking any further action. Twenty-two percent of the patients said that after re-sting they would immediately administer their EpiPen. Proper EpiPen administration technique was demonstrated by 44% of the patients. Having not reached the maintenance dose correlated with a better compliance with carrying of the EpiPen. EpiPen instruction provided by an allergist correlated with a better EpiPen administration technique by the patients. CONCLUSION Many patients with venom allergy hold wrong ideas about after-sting behavior. Compliance with carrying EpiPen at all times and the ability to correctly administer it are both poor in most patients. Thorough and probably repeated instruction, both written and oral, provided by knowledgeable physicians is mandatory.
Gingival crevicularfluid osteoprotegerin levels in Indian population

Background: Initial research indicated that higher concentration of osteoprotegerin (OPG) is associated with healthy periodontium (protective) and its concentration decreases as the periodontal disease progresses. However, till date, there are no studies to investigate the levels of OPG in gingival crevicular fluid (GCF) after the treatment of periodontitis. Hence, the present study was carried out to assess its concentration in GCF to find out their association if any, and to explore its possible use as a ‘novel bone marker’ of the host modulation of periodontal disease. Materials and Methods: Sixty-four subjects were divided into 4 groups (16 each), based on clinical attachment loss (CAL) and radiological parameters (bone loss); healthy (group I), gingivitis (group II), slight periodontitis (group III), and moderate-to-severe periodontitis (group IV). Moderate-to-severe periodontitis subjects, after nonsurgical periodontal treatment, (SRP) constituted group V. GCF samples were collected to estimate the levels of OPG using enzyme-linked immunosorbent assay (ELISA). The Kruskal-Wallis, Man-Whitney U test, and Wilcoxon signed-rank tests were carried out to compare OPG levels among groups. The Spearman rank correlation test was used to correlate OPG levels between the study groups and the clinical parameters; P < 0.05 was considered significant. Results: The highest mean OPG concentration in GCF was obtained for group I (162.47 ± 51.171 pg/ μL) and the least for group IV (10.92 ± 1.913 pg/μL), suggesting a negative correlation between OPG concentration and CAL. OPG concentrations in GCF after the treatment of group IV increased from 10.92 ± 1.913 pg/μL to 15.63 ± 4.679 pg/μL. Conclusion: OPG concentration in GCF was inversely proportional to CAL and not an active progression factor for periodontal disease. Further, after the treatment of moderate-to-severe periodontitis subjects (group IV), OPG concentrations increased. Hence, it can be concluded that OPG could be considered as a ‘novel bone marker’ the host modulation of periodontal disease.
Discrete Intracellular Signaling Domains of Soluble Adenylyl Cyclase: Camps of cAMP?

Soluble adenylyl cyclase can function in the nucleus, defining a nuclear microdomain of adenosine 3′,5′-monophosphate (cAMP) signaling. Bundey and Insel discuss the evidence for discrete signaling microdomains of cAMP, including the nucleus and caveolae, and conclude that such microdomains may be defined by the localized, subcellular expression of adenylyl cyclase isoforms.
Designing and evaluating Brain Powered Games for cognitive training and rehabilitation in at-risk African children

Background. Valid, reliable, accessible, and cost-effective computer-training approaches can be important components in scaling up educational support across resource-poor settings, such as sub-Saharan Africa. The goal of the current study was to develop a computer-based training platform, the Michigan State University Games for Entertainment and Learning laboratory's Brain Powered Games (BPG) package that would be suitable for use with at-risk children within a rural Ugandan context and then complete an initial field trial of that package. Methods. After game development was completed with the use of local stimuli and sounds to match the context of the games as closely as possible to the rural Ugandan setting, an initial field study was completed with 33 children (mean age = 8.55 ± 2.29 years, range 6–12 years of age) with HIV in rural Uganda. The Test of Variables of Attention (TOVA), CogState computer battery, and the Non-Verbal Index from the Kaufman Assessment Battery for Children, 2nd edition (KABC-II) were chosen as the outcome measures for pre- and post-intervention testing. The children received approximately 45 min of BPG training several days per week for 2 months (24 sessions). Results. Although some improvements in test scores were evident prior to BPG training, following training, children demonstrated clinically significant changes (significant repeated-measures outcomes with moderate to large effect sizes) on specific TOVA and CogState measures reflecting processing speed, attention, visual-motor coordination, maze learning, and problem solving. Conclusions. Results provide preliminary support for the acceptability, feasibility, and neurocognitive benefit of BPG and its utility as a model platform for computerized cognitive training in cross-cultural low-resource settings.
Computational exposure assessment of electromagnetic fields generated by an RFID system for mother–newborn identity reconfirmation

Radio frequency identification (RFID) is an innovative technology currently applied in a large number of industrial and consumer applications. The spread of RFID technology does not correspond to a parallel increase in studies on its possible impact on health in terms of electromagnetic field (EMF) exposure. The aim of this paper is to estimate, by computational techniques, the EMF generated by passive RFID systems for mother–newborn identity reconfirmation. The computation was performed on realistic models of newborn and mother for three different reader positions. The compliance with EMF exposure guidelines was investigated as a function of the change in reader–tag specifications (magnetic field threshold and maximum distance of the reader to awake the tag) and time of use of the reader close to the body. The results show that attention should be paid to the identification of the optimal reader–tag technical specifications to be used in this type of application. That should be done by an accurate exposure assessment investigation, in particular for newborn exposure. The need to reduce the exposure time as much as possible indicates the importance of specific training on the practical applications of the RFID (DATALOGIC J‐series, Bologna, Italy) device.
