Fast Optimal Antenna Placement for Distributed MIMO Radar with Surveillance Performance

In this letter, we demonstrate an optimization problem of antenna placement of distributed multi-input multi- output (MIMO) radar. To evaluate the surveillance performance of the radar system, a coverage ratio is proposed as a criterion. Since the problem is of extremely huge computational complexity due to its complicated objective function and high dimensionality, we propose a solution that contains two parts: 1) a low- complexity method to simplify the objective function; 2) a placement algorithm based on particle swarm optimization (PSO) to deal with the challenge of high dimensionality. We also analyse the computational complexity of our solution. Simulation results verify the validity and advantage in computational complexity of our solution. Our contributions include a novel optimization placement model of distributed MIMO radar and a computational efficient solution to establish the optimal positions of antennas.
RECONSTRUCTION OF CONSISTENT 3D CAD MODELS FROM POINT CLOUD DATA USING A PRIORI CAD MODELS

Abstract. We address the reconstruction of 3D CAD models from point cloud data acquired in industrial environments, using a pre-existing 3D model as an initial estimate of the scene to be processed. Indeed, this prior knowledge can be used to drive the reconstruction so as to generate an accurate 3D model matching the point cloud. We more particularly focus our work on the cylindrical parts of the 3D models. We propose to state the problem in a probabilistic framework: we have to search for the 3D model which maximizes some probability taking several constraints into account, such as the relevancy with respect to the point cloud and the a priori 3D model, and the consistency of the reconstructed model. The resulting optimization problem can then be handled using a stochastic exploration of the solution space, based on the random insertion of elements in the conﬁguration under construction, coupled with a greedy management of the conﬂicts which efﬁciently improves the conﬁguration at each step. We show that this approach provides reliable reconstructed 3D models by presenting some results on industrial data sets.
A Binary Krill Herd Approach for Feature Selection

Meta-heuristic-based feature selection has been paramount in the last years, mainly because of its simplicity, effectiveness and also efficiency in some cases. Such approaches are based on the social dynamics of living organisms, and can vary from birds, bees, bats and ants. Very recently, an optimization algorithm based on krill herd (KH) was proposed for continuous-valued applications, and it has been more accurate than some state-of-the-art techniques. In this paper, we propose a binary optimization version of KH technique, and we validate it for feature selection purposes in several datasets. The experiments showed the proposed technique outperforms three other meta-heuristic-based approaches for this task, being also so fast as the compared techniques.

In vivo effects of the antiglucocorticoid RU 486 on glucocorticoid and cytokine responses to Escherichia coli endotoxin

The endogenous adrenocortical response to sepsis is critical for host survival. The in vivo interactions among the endogenous glucocorticoid response, the induction of cytokines, and host survival during endotoxemia were explored in this study by use of the glucocorticoid receptor antagonist RU 486. Male Lewis rats underwent sterile insertion of a right jugular venous catheter. After a 72-h recovery period, animals received a 50% lethal dose of Escherichia coli endotoxin (2.5 mg/kg) via the catheter after pretreatment for 30 min prior to lipopolysaccharide (LPS) treatment with (i) vehicle alone intravenously (i.v.) (-corticosterone [-Cort]/-RU 486/+LPS) (n = 10), (ii) the antiglucocorticoid RU 486 (10 mg/kg) i.v. (-Cort/+RU 486/+LPS) (n = 11), or (iii) RU 486 (10 mg/kg) i.v. in animals that had undergone subcutaneous implantation of a corticosterone pellet at the time of catheter insertion (+Cort/+RU 486/+LPS) (n = 10). Except in animals receiving corticosterone pretreatment, baseline plasma corticosterone levels were low in all groups. Plasma corticosterone levels increased significantly (P less than 0.001) above the baseline following LPS administration. Animals in the -Cort/+RU 486/+LPS-treated group exhibited significantly increased mortality (P less than 0.001), with only 9% of the animals surviving at 72 h, as well as significantly increased plasma interleukin-6 levels, compared with animals receiving the vehicle alone (-Cort/-RU 486/+LPS), which showed 50% mortality. Pretreatment with corticosterone and RU 486 (+Cort/+RU 486/+LPS) significantly (P less than 0.001) reversed the mortality observed with RU 486 pretreatment alone (-Cort/+RU 486/+LPS), with 70% of the animals surviving at 72 h, and significantly attenuated the peak plasma tumor necrosis factor and interleukin-6 responses to LPS, compared with those in the animals treated with vehicle alone. These data demonstrate that the blockade of glucocorticoid binding by RU 486 increases LPS-induced mortality. The reversal of this effect by the induction of hypercorticosteronemia prior to RU 486 and LPS exposure (+Cort/+RU 486/+LPS) improves survival and is further associated with significant attenuation of cytokine production. Therefore, these data suggest that the protective effect of the endogenous glucocorticoid response to acute endotoxemia may result from the down-regulation of a potentially lethal cytokine response.
High-Resolution CT Imaging of Carotid Artery Atherosclerotic Plaques

BACKGROUND AND PURPOSE: Plaque morphologic features have been suggested as a complement to luminal narrowing measurements for assessing the risk of stroke associated with carotid atherosclerotic disease, giving rise to the concept of “vulnerable plaque. ” The purpose of this study was to evaluate the ability of multidetector-row CT angiography (CTA) to assess the composition and characteristics of carotid artery atherosclerotic plaques with use of histologic examination as the gold standard. MATERIALS AND METHODS: Eight patients with transient ischemic attacks who underwent carotid CTA and “en bloc” endarterectomy were enrolled in a prospective study. An ex vivo micro-CT study of each endarterectomy specimen was obtained, followed by histologic examination. A systematic comparison of CTA images with histologic sections and micro-CT images was performed to determine the CT attenuation associated with each component of the atherosclerotic plaques. A computer algorithm was subsequently developed that automatically identifies the components of the carotid atherosclerotic plaques, based on the density of each pixel. A neuroradiologist's reading of this computer analysis was compared with the interpretation of the histologic slides by a pathologist with respect to the types and characteristics of the carotid plaques. RESULTS: There was a 72.6% agreement between CTA and histologic examination in carotid plaque characterization. CTA showed perfect concordance for calcifications. A significant overlap between densities associated with lipid-rich necrotic core, connective tissue, and hemorrhage limited the reliability of individual pixel readings to identify these components. However, CTA showed good correlation with histologic examination for large lipid cores (κ = 0.796; P < .001) and large hemorrhages (κ = 0.712; P = .102). CTA performed well in detecting ulcerations (κ = 0.855) and in measuring the fibrous cap thickness (R2 = 0.77; P < .001). CONCLUSION: The composition of carotid atherosclerotic plaques determined by CTA reflects plaque composition defined by histologic examination.
Nutritional composition and antioxidant activities of 18 different wild Cantharellus mushrooms of Northwestern Himalayas

A total of 18 wild edible mushrooms of Cantharellus species were collected from northwestern Himalayan region of India. The basic composition (moisture, total carbohydrates, dietary fiber, crude fat, ash, nitrogen and protein) and amino acid contents (by high-performance liquid chromatography) of these wild edible mushrooms were determined. The macronutrient profile in general revealed that the wild mushrooms were rich sources of protein and carbohydrates, and had low amounts of fat. Total phenolics and antioxidant activity from water and methanolic extracts of these mushrooms were also determined. These wild mushrooms also had significant amount of phenol content and antioxidant capacity. Studies also provide the precise antioxidant status of 18 indigenous species of mushrooms, which can serve as a useful database for the selection of mushrooms for the function of preparation of mushroom-based nutraceutics.
Diversity of mosquitoes (Diptera Culicidae) in protected na - tural parks from Valencian Autonomous Region (Eastern Spain)

Several larval samplings of mosquitoes (Diptera Culicidae) were carried out between 20082011, throughout very diverse larval biotopes located in thirteen protected natural parks from Eastern Spain, offering new information about the faunistic diversity of mosquitoes in these protected areas. Biodiversity was analyzed in terms of alpha, beta and gamma components, with the aim of comparing mosquito diversity according to the typology of the natural parks under study. A total of 15355 specimens belonging to 25 different mosquito species and 6 genera were collected and identified. Diversity analysis indicated higher diversity for Inland Mountainous Areas (IMAs) with a low degree of interspecific dominance in these communi ties, while Coastal Wetlands and Marshes registered the lowest observed diversity and a high degree of interespecific dominance. The cluster analysis revealed the relationship between the categories (IMA, CMA, CWM), while the Principal Components Analysis proved the re lationship between larval abundance and the categories studied.
Global Functioning and Suicide Among Chinese Rural Population Aged 15–34 Years: A Psychological Autopsy Case‐Control Study *

Abstract: As the relationship between global functioning and young suicide remains unclear in rural China, this study was aimed to explore the relationship between them. Data of 391 rural suicides and 416 controls, all aged 15–34 years in three provinces in China were used for this study. The Global Assessment of Functioning (GAF) scale was adopted to assess global functioning of suicides and controls. The results showed that GAF score was stronger than mental illness in predicting suicide in China. Different correlates of GAF score were found between suicides and controls. Unsurprisingly, GAF score was significantly correlated with mental illness in both suicides and controls. Different characteristics were also found among three types of suicide which were classified using GAF score. Assessing global functioning is useful and GAF scale should be regularly used in suicide prevention practice.
When and Why Aggression Fortifies the Needs of Ostracized Individuals

Ostracism is a painful event that many individuals experience. Research has demonstrated that aggression is a common response by those who experience the pain of ostracism and that aggression may play an important role in recovery from the pain of these events. We first review social psychological theories that suggest an evolved ostracism detection system, highlighting current evidence that supports such a system. We then review the literature on the ostracism→aggression relation, and focus on research arguing that aggression severs as a way for ostracized individuals to fortify their threatened basic needs. Finally, we propose an extension to Williams’s (2009) need-recovery hypothesis on how to predict whether individuals will respond with proor anti-social behaviors in response to ostracism. We argue that an important factor in ostracized individuals’ attribution processes is their likelihood of being reincluded by the target of their subsequent behavioral responses. Future areas of research are proposed to investigate how this extension informs research on individuals respond to both shortterm and extended episodes of ostracism.
Comparison of Transcriptional Profiles of Flavonoid Genes and Anthocyanin Content During Fruit Development in Chinese Bayberry(myrica Rubra Sieb. & Zucc.)

Anthocyanins in the fruit of the Chinese bayberry (Myrica rubra Sieb. & Zucc.) are a major focus of research. In the current study, we investigated anthocyanin, total flavonoid, and phenolic acid profiles, as well as the expression of genes involved in anthocyanin biosynthesis, during fruit development in eight cultivars of Chinese bayberry. Total flavonoid and phenolic acid levels were relatively higher in green stage fruits, decreased in turning stage fruit, and increased in ripe fruit. Anthocyanin profiling revealed a contrasting pattern; anthocyanin levels were lower during fruit ripening and increased sharply in mature fruit. Expression profiling of anthocyanins showed coordinated expression of multiple anthocyanin biosynthesis genes during the development process. However, different genes played a predominant role at different stages. Flavanone3-hydroxylase and flavonoid-3′-hydroxylase played predominant roles in the accumulation of total flavonoids and phenolic acids during the early stage of development, whereas chalcone synthase played a predominant role in the accumulation of anthocyanins during the ripening stage, implying regulation of anthocyanins varies with development stage.
SNP genotyping and population genomics from expressed sequences – current advances and future possibilities

With the rapid increase in production of genetic data from new sequencing technologies, a myriad of new ways to study genomic patterns in nonmodel organisms are currently possible. Because genome assembly still remains a complicated procedure, and because the functional role of much of the genome is unclear, focusing on SNP genotyping from expressed sequences provides a cost‐effective way to reduce complexity while still retaining functionally relevant information. This review summarizes current methods, identifies ways that using expressed sequence data benefits population genomic inference and explores how current practitioners evaluate and overcome challenges that are commonly encountered. We focus particularly on the additional power of functional analysis provided by expressed sequence data and how these analyses push beyond allele pattern data available from nonfunction genomic approaches. The massive data sets generated by these approaches create opportunities and problems as well – especially false positives. We discuss methods available to validate results from expressed SNP genotyping assays, new approaches that sidestep use of mRNA and review follow‐up experiments that can focus on evolutionary mechanisms acting across the genome.
A Bounded Degree Property and Finite-Cofiniteness of Graph Queries

We provide new techniques for the analysis of the expressive power of query languages for nested collections. These languages may use set or bag semantics and may be further complicated by the presence of aggregate functions. We exhibit certain classes of graphs and prove that properties of these graphs that can be tested in such languages are either finite or cofinite. This result settles the conjectures of Grumbach, Milo, and Paredaens that parity test, transitive closure, and balanced binary tree test are not expressible in bag languages like BALG of Grumbach and Milo and LQL of Libkin and Wong. Moreover, it implies that many recursive queries, including simple ones like test for a chain, cannot be expressed in a nested relational language even when aggregate functions are available. In an attempt to generalize the finite-cofiniteness result, we study the bounded degree property which says that the number of distinct inand out-degrees in the output of a graph query does not depend on the size of the input if the input is "simple. " We show that such a property implies a number of inexpressibility results in a uniform fashion. We then prove the bounded degree property for the nested relational language.
3DCapture: 3D Reconstruction for a Smartphone

We propose a method of reconstruction of 3D representation (a mesh with a texture) of an object on a smartphone with a monocular camera. The reconstruction consists of two parts – real-time scanning around the object and postprocessing. At the scanning stage IMU sensors data are acquired along with tracks of features in video. A special care is taken to comply with 360 scan requirement. All these data are used to build a camera trajectory using bundle adjustment techniques after scanning is completed. This trajectory is used in calculation of depth maps, which then are used to construct a polygonal mesh with overlaid textures. The proposed method ensures tracking at 30 fps on a modern smartphone while the post-processing part is completed within 1 minute using an OpenCL compatible mobile GPU. In addition, we show that with a few modifications this algorithm can be adopted for human face reconstruction.
Localizing with Passive UHF RFID Tags Using Wideband Signals

Localization of positions and detection of objects is a key aspect in today’s applications and, although the topic exists a while ago, it is still under ongoing research. The introduction of global navigation satellite systems (GNSS), particularly GPS [1], and its improvements with accuracies down to a few meters, was a huge step towards ubiquitous localization [2, 3]. This is almost valid for outdoor environments, whereas indoor localization is still a challenging issue [4, 5]. The reason for that is the demanding, dynamic indoor environment, causing severe multipath fading, leading to hard predictable propagation models thus influencing time, power and phase measurements. However, in the past, much effort has been put into designing high accurate indoor localization systems, including technologies like ultrasonic sound, infrared light, Wi-Fi, Bluetooth, ZigBee, cellular mobile communication (GSM, UMTS), ultrawideband and RFID just to mention a few of them. Despite all the effort, there is no outstanding technology comprising all indoor localization contingencies as every technology in use has its advantages and disadvantages regarding accuracy, availability, complexity and costs.
Optimizations of Eiffel programs: SmallEiffel, the GNU Eiffel Compiler

The design of the Eiffel language makes it possible to perform global optimizations on Eiffel programs. We describe some of the techniques we used in SmallEiffel, The GNU Eiffel Compiler, to generate highly efficient excecutables for Eiffel programs. Most of these techniques-related to global analysis or not-may also be applied to other object oriented languages.
Measuring social relations with multiple datasets

Because people have different levels of engagement with each other, measuring social relations is difficult. In this work, we propose a method of measuring social relations with multiple datasets and demonstrate the differences with empirical evidence. Our empirical findings demonstrate that people use different communication media channels differently. Therefore, we suggest that in order to understand social structures, one should use several kinds of data sources and not just depend on a single dataset. Our datasets include mobile phone data gathered with handset-based measurements and data from OtaSizzle online social media services. By means of social network analysis, we show that the online social media services have a different friendship network than the networks based on mobile phone communication. The mobile phone communication networks, however, have a very similar structure. These results are encouraging as previous research also indicates differences in the communication networks.
The immunoglobulin heavy-chain enhancer functions as the promoter for I mu sterile transcription

We demonstrate that the immunoglobulin heavy-chain enhancer functions as the promoter for I mu sterile transcription. The enhancer itself, when placed 5' to the bacterial cat or neo genes, is able to direct transcription by using heterogeneous start sites that are generally the same as those found with bona fide I mu transcripts. In general, promoter activity is dependent on the same sequence motifs important for enhancer activity. However, it appears that a mutation within the conserved octanucleotide ATTTGCAT has a much more severe effect on the promoter activity of the enhancer than the same mutation has on its enhancer activity. This result is consistent with the known role of the octanucleotide as a promoter element, and this is discussed in relation to the biological role of sterile transcription.
The generation of mono-energetic electron beams from ultrashort pulse laser–plasma interactions

The physics of the interaction of high-intensity laser pulses with underdense plasma depends not only on the interaction intensity but also on the laser pulse length. We show experimentally that as intensities are increased beyond 1020 W cm−2 the peak electron acceleration increases beyond that which can be produced from single stage plasma wave acceleration and it is likely that direct laser acceleration mechanisms begin to play an important role. If, alternatively, the pulse length is reduced such that it approaches the plasma period of a relativistic electron plasma wave, high-power interactions at much lower intensity enable the generation of quasi-mono-energetic beams of relativistic electrons.
Differential effects of assisted cycling therapy on short-term and working memory of adolescents with Down syndrome

ABSTRACT Persons with Down syndrome (DS) suffer from prefrontal cortex dysfunction and deficits in executive functions. The current study examined the effects assisted cycling therapy (ACT) on short-term (STM) and working memory (WM) in adolescents with DS. During ACT, the cadence of participants on a stationary bicycle was augmented with an electrical motor to 180% of the voluntary cadence. Participants completed eight weeks of ACT (n = 17), eight weeks of voluntary cycling (VC) at their own preferred cadence (n = 16), or eight weeks of no cycling (np ≥ .149) and working memory improved only in the ACT group (Hedge’s g = 1.66; p = .003). The results indicate that assisted high-cadence cycling (i.e. ACT) produces superior neural benefits in the dorsolateral prefrontal cortex compared to VC.
