Face recognition method based on Within-class Clustering SVM

A face recognition method based on within-class Clustering SVM (CCSVM) is presented in this paper in order to decrease the negative effect caused by noisy training samples in the recognition process. Based on the discontinuity of finite samples distribution in the high dimension space and the existence of noisy samples, first, we re-cluster samples within the class, find out the cluster centres to form the virtual classes, and then divide virtual classes of all the classes by SVM. Experiment results show that this method follows the distribution law of points in high-dimensional space and can achieve better performance than some traditional methods.
Association Between Parents’ Marital Status and the Development of Purpose, Hope, and Self-Esteem in Adolescents in Hong Kong

This study investigates the role of parents’ marital status in adolescents’ mental well-being. Although the separation of parents is generally regarded as a negative condition on adolescents’ growth, we find evidence of strong positive development in certain areas. Faced with an adverse family background, even though teenagers might have lower happiness and life satisfaction, they come to develop stronger purpose in life, higher hope for the future, and higher self-esteem. We argue that this is because the tougher circumstances force them to become independent and develop their own identity. On the other hand, these attributes are found to be lower among older adolescents in “normal” family backgrounds, which provide an interesting contrast to prior research, which has argued that intact families are positive for development. The results of this study have strong implications for the study of teenage well-being.
Exploring the Meanings of Making Traditional Arts and Crafts among Older Women in Crete, Using Interpretative Phenomenological Analysis

Aim: The aim of the study was to investigate the meanings of making traditional arts and crafts among older, retired women living in rural Crete, and the contribution of these occupations to wellbeing. Previous relevant research, conducted mainly in the United Kingdom and United States, had largely neglected the experiences of art-making in societies with strong cultural traditions of art-making. Method: Semi-structured interviews were conducted in Greek to collect qualitative accounts from 12 women aged over 65 years. The data were interpreted according to published guidelines for interpretative phenomenological analysis. Findings: The women identified various forms of art-making that were indigenous, such as weaving, lace-making and painting holy icons. They expressed deep respect for artistic traditions and took pride in preserving and teaching traditional skills and designs. They perceived art-making as promoting continuity of self, social status and spiritual wellbeing. Art-making was also used as a coping strategy for the challenges of later life, such as bereavement. Conclusion: Older women in Crete valued their involvement in traditional forms of art-making. These occupations enhanced wellbeing in several ways. Participants gained status, and a culturally recognised role in the community, from preserving and transmitting the skills required for indigenous forms of art and craft work.
Multi-Label Zero-Shot Human Action Recognition via Joint Latent Embedding

Human action recognition refers to automatic recognizing human actions from a video clip, which is one of the most challenging tasks in computer vision. In reality, a video stream is often weakly-annotated with a set of relevant human action labels at a global level rather than assigning each label to a specific video episode corresponding to a single action, which leads to a multi-label learning problem. Furthermore, there are a great number of meaningful human actions in reality but it would be extremely difficult, if not impossible, to collect/annotate video clips regarding all of various human actions, which leads to a zero-shot learning scenario. To the best of our knowledge, there is no work that has addressed all the above issues together in human action recognition. In this paper, we formulate a real-world human action recognition task as a multi-label zero-shot learning problem and propose a framework to tackle this problem. Our framework simultaneously tackles the issue of unknown temporal boundaries between different actions for multi-label learning and exploits the side information regarding the semantic relationship between different human actions for zero-shot learning. As a result, our framework leads to a joint latent embedding representation for multi-label zero-shot human action recognition. The joint latent embedding is learned with two component models by exploring temporal coherence underlying video data and the intrinsic relationship between visual and semantic domain. We evaluate our framework with different settings, including a novel data split scheme designed especially for evaluating multi-label zero-shot learning, on two weakly annotated multi-label human action datasets: Breakfast and Charades. The experimental results demonstrate the effectiveness of our framework in multi-label zero-shot human action recognition.
High gain air-filled H-plane horn antenna with dielectric load in W-band based on low-cost PCB technology

A high gain W-band air-filled H-plane horn antenna is designed and fabricated using low-cost PCB technology. The antenna consists of 4 substrate layers. A portion of the dielectric substrate is removed from the middle two layers to form a hollow horn. A rectangular-slotted dielectric load is added at the end of the antenna providing 4 dB gain enhancement, as well as better impedance matching. Measured results show that the impedance bandwidth is wider than 18 GHz(85–103 GHz) and a peak gain of 15.5 dBi at 97.5 GHz is achieved.
Making Sense of Sickness and Care: An Ethnography of Health in a West Midlands Town

The paper presents findings from an investigation into individual perceptions of health and health care. The investigation employed an ethnographic or qualitative approach and was located in a theoretical framework deriving from Schutz and Heller. While Heller's study of everyday life is used to note how people make sense through constructing 'stories', Schutz's notions on scientific constructs are employed to demonstrate the need for, and problems with, social scientific interpretation. In the conclusion, however, other Schutzian ideas are found wanting, and reference is made to hegemony as a representation of the context of many experiences and perceptions.
Method for the calculation of velocity, rate of flow and viscous drag in arteries when the pressure gradient is known

The experiments of McDonald and his co-workers (McDonald, 1952, 1955; Helps & McDonald, 1953) have shown that in the larger arteries of the rabbit and the dog there is a reversal of the flow. Measurements of the pressure gradient (Helps & McDonald, 1953) showed a phase-lag between pressure gradient and flow somewhat analogous with the phase-lag between voltage and current in a conductor carrying alternating current, and the simple mathematical treatment given below has strong similarities with the theory of the distribution of alternating current in a conductor of finite size.
INFLUENCE OF NUTRIENT ENRICHMENT ON STRUCTURING DIATOM COMMUNITIES IN A GLACIAL MELTWATER STREAM, MCMURDO DRY VALLEYS, ANTARCTICA

In the arid McMurdo Dry Valleys of East Antarctica, glacial meltwater streams flow for 6-10 weeks during the austral summer. Harbored in these meltwater streambeds are diatom communities, which are part of a microbial mat matrix. These mat assemblages endure desiccating winters and become reactivated upon rehydration during the austral summer. Water is considered the major limiting resource in the dry valley stream ecosystems, and the variable flow of meltwater has been shown to regulate the biomass and growth of these algal mats. However, other environmental variables could influence the structure of these mat communities. In this thesis, the influences of nutrients are examined as a regulatory control on diatom community structure. This thesis draws from previous experimentation using Nutrient Diffusing Substrates (NDS) with nitrate and phosphate amendments that were left in Green Creek for algae to colonize. Characterization of diatom communities that grew on NDS units showed that nitrate enrichments significantly altered diatom relative abundance, with an increase in Fistulifera pelliculosa to 21% relative abundance in nitrate treatments compared to other nutrient amendments, which had less than 5% F. pelliculosa abundance. Other nutrient amendments showed only a marginal influence on diatom relative abundance. In addition, nitrate and phosphate amendments showed greater average diatom densities relative to the control treatments, with the greatest densities occurring in nitrate amendments. These results suggest that nutrients influence diatom growth and accrual, although stream hydrology and geomorphology likely have a greater influence on regulating the structure of these diatom communities within the microbial mat matrix. Moreover, the results from this thesis can help to predict the response by diatom communities to expected landscape changes in McMurdo Dry Valley streams as a function of climate change, such as increase flow and subsequent nutrient enrichment. ii PREFACE I want to thank Dr. Diane McKnight for providing me with many opportunities to explore aquatic ecology through hands-on learning in her lab.

Piecing together the segmentation jigsaw using context

We present an approach to jointly solve the segmentation and recognition problem using a multiple segmentation framework. We formulate the problem as segment selection from a pool of segments, assigning each selected segment a class label. Previous multiple segmentation approaches used local appearance matching to select segments in a greedy manner. In contrast, our approach formulates a cost function based on contextual information in conjunction with appearance matching. This relaxed cost function formulation is minimized using an efficient quadratic programming solver and an approximate solution is obtained by discretizing the relaxed solution. Our approach improves labeling performance compared to other segmentation based recognition approaches.
Efficacy of an alcohol / chlorhexidine hand hygiene program in a hospital with high rates of nosocomial methicillin-resistant Staphylococcus aureus ( MRSA ) infection 253

In 1824, The London Times reported: “A wonderful instrument called the Stethoscope . is now in complete vogue at Paris. It is merely a hollow wooden tube, about a foot in length . One end is applied to the breast of the patient. The other to the ear of the physician, and according to the different sounds, harsh, hollow, soft, loud etc., he judges of the state of the disease. ” It had been 10 years since its invention by the French physician, René Laënnec, and the stethoscope was widely in use in France. Elsewhere, there was resistance. It was argued that the stethoscope came between the patient and doctor and threatened the time-honoured art of laying the ear upon the chest.
Sex, age, and family differences in the chemical composition of owl monkey (Aotus nancymaae) subcaudal scent secretions

Numerous behavioral studies have shown that animals use olfactory cues as inbreeding avoidance or kin avoidance mechanisms, implying that scent is unique to families. However, few studies have analyzed the chemical profile of a scent and ascertained the messages that are conveyed in scent secretions. Owl monkeys (Aotus nancymaae) are socially monogamous primates that utilize scent when interacting with foreign conspecifics. This suggests there is a difference in the chemical composition of scent marks. We chemically analyzed sub‐caudal gland samples from three families of captive owl monkeys (Aotus nancymaae). Samples were analyzed by capillary GC‐MS and relative retention time and fragment pattern was compared with known standards. Gland samples were high in large plant‐based shikikate metabolites and fatty ketones; alcohols, acids, and acetates were virtually absent. Gender, age, and family could be reliably classified using discriminant analysis (92.9, 100, and 100%, respectively). Female scent profiles were greater in concentration of aromatic plant metabolites, possibly the result of a different diet or physiological differences in female metabolism as compared to male. Offspring of adult age still living in their natal group showed a less complex chemical profile than their parents. Finally, each family had its own unique and complex chemical profile. The presence of family scent may play a role in mediating social interactions. Am. J. Primatol. 70:12–18, 2007. © 2007 Wiley‐Liss, Inc.
Geolocalization of proxied services and its application to fast-flux hidden servers

Fast-flux is a redirection technique used by cyber-criminals to hide the actual location of malicious servers. Its purpose is to evade identification and prevent or, at least delay, the shutdown of these illegal servers by law enforcement. This paper proposes a framework to geolocalize fast-flux servers, that is, to determine the physical location of the fast-flux networks roots (mothership servers) based on network measurements. We performed an extensive set of measurements on PlanetLab in order to validate and evaluate the performance of our method in a controlled environment. These experimentations showed that, with our framework, fast-flux servers can be localized with similar mean distance errors than non-hidden servers, i.e. approximately 100 km. In the light of these very promising results, we also applied our scheme to several active fast-flux servers and estimated their geographic locations, providing then statistics on the locations of "in the wild" fast-flux services.
Smoothed projections in finite element exterior calculus

The development of smoothed projections, constructed by combining the canonical interpolation operators defined from the degrees of freedom with a smoothing operator, have proved to be an eective tool in finite element exterior calculus. The advan- tage of these operators is that they are L 2 bounded projections, and still they commute with the exterior derivative. In the present paper we generalize the construction of these smoothed projections, such that also non quasi-uniform meshes and essential boundary conditions are covered. The new tool introduced here is a space dependent smoothing operator which commutes with the exterior derivative.
Social tags as news event detectors

The objective of this study was to investigate the use of tags in iReport to detect breaking news in terms of coverage and immediacy. Coverage refers to the extent to which news reported in mainstream media can also be detected in iReport, while immediacy refers to the promptness of news reported in mainstream media vis-à-vis those detected in iReport. A total of 10 ground truth events were identified from mainstream media between 1 April 2008 and 31 December 2008. Additionally, 481,455 tags from 118,545 postings were drawn from iReport in the same period. Relative frequencies of the top 200 most frequently-used tags were analysed to check for spikes and bursts. Based on the results, four main findings emerged. First, the performance of using spikes and bursts to detect news events was found to be comparable. Next, news events detected via spikes and bursts were found to lag ranging from a few days to more than a week compared to the dates reported by mainstream media. Third, news events deemed to be significant by professional journalists did not always attract a high level of interest from iReport contributors. Finally, even though citizen journalism transcends national boundaries via the internet, news posted to iReport seemed to show a proclivity towards local context.
Orthography and Respelling in Teaching Spanish

ing the patterns on the fly, as it were. It would be possible, of course, to use tie lines as a clue that the three a's of ? Que va a hacer? represent only one [a] in normal colloquial speech, but students seem to react to this as meaning length. Other problems, of less consequence than those discussed above, include the fact that the orthography encourages the pronunciation of v as different from /b/ in its two allophones [b] and [b]; that it disguises the morphophonemic alternations among the nasalsJuan viene [hw~mbydn&i], invierno [imbydrnob], enviar [6mbyrfl], etc., and that it tempts some students to pronounce "dead" letters in guerra, hotel. Whatever one's feeling about these difficulties that the orthography introduces into student pronunciation,3 the difficulties that arise because important linguistic facts are omitted from orthographical indication must be acknowledged to be considerable. These omissions include pitch, juncture, and stress. Pitch levels are not marked in any way, even if certain contours can be said to be shown by punctuation-we say if, because as far as we can determine, no single meaningful contour is consistently and unambiguously marked by punctuation. Juncture is also indicated by punctuation sometimes, but by no means unambiguously. And even stress, for the largely unambiguous marking of which Spanish orthography is justly respected, is shown on the word level only, not on the phrase level where it is really important (since very few utterances are just a word). An example of the omission of pitch levels4 which results in ambiguity might be this one: The spelling Va al centro? represents both of the following utterances, which are quite different in meaning:
Cored network biomarker of carcinogenesis from early and late stage bladder cancer samples

Cancers is the major cause of death around the world for a long time, and it occurs at DNA, RNA or protein level. In this study, we use the systems biology approach to construct the protein-protein interaction (PPI) networks for early and late stage bladder cancer. By comparing network of these two stage, core and specific network markers were identified by the intersection and distinction of key proteins. We identified 18 significant proteins(network marker) for the cored network and their carcinogenesis relevance values(CRVs) We construct the CPPIN and NPPIN network structures for both stage bladder cancer. We also identified 3388 cancer protein pairs and 3151 non-cancer protein pairs for the early stage bladder cancer, respectively. And build 634 cancer protein pairs and 1185 non cancer protein pairs for the late stage bladder cancer, respectively. Primary pathway analysis shows that proteins BRAC1 and CUL3 related to the function of cell growth, UBC should be only a housekeeping like protein because it does not involve in any important functions. More validation of these network markers by both literature and novel test set could help us reveal more mechanisms of bladder cancer in the future.
Cytogenetic Investigation in a Group of Ten Infertile Men with Non-Obstructive Azoospermia: First Algerian 46, XX Syndrome

Background: In Algeria, the data on infertility and its various causes are rare. Recently, the introduction of assisted reproduction has allowed expecting that 300000 couples, which represent 7% of couples of reproductive age, face difficulty conceiving a child. Knowing that most idiopathic cases are likely to be due to chromosomal abnormalities, we aimed to investigate genetic defects by karyotype analysis in Algerian infertile men, using peripheral blood lymphocytes. Methods: A cytogenetic study was conducted on 10 men from infertile couples by Karyotype analysis of R-banding performed by lymphocyte culture technique. Fluorescence in situ hybridization was performed and molecular abnormalities were investigated by polymerase chain reaction. Follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were evaluated by immunoradiometric method. Results: Chromosomal abnormalities were observed in 30% of the patients. We identified a homogenous Klinefelter syndrome patient with 47, XXY karyotype, a mosaic Klinefelter syndrome patient with 47, XXY/46, XY karyotype and a 46, XX male. Fluorescence in situ hybridization showed that the sex-determining region Y was translocated to the short arm of the X chromosome in patient with 46, XX chromosomal constitution and the presence of the SRY gene was confirmed by polymerase chain reaction and electrophoresis. Conclusion: The occurrence of chromosomal abnormalities in 30% of the infertile men strongly supports the inclusion of routine cytogenetic testing for diagnostic establishment and suitable counseling for couples seeking for assisted reproduction technologies.
Practical speculative parallelization of variable-length decompression algorithms

Variable-length coding is widely used for efficient data compression. Typically, the compressor splits the original data into blocks and compresses each block with variable-length codes, hence producing variable-length compressed blocks. Although the compressor can easily exploit ample block-level parallelism, it is much more difficult to extract such coarse-grain parallelism from the decompressor because a block boundary cannot be located until decompression of the previous block is completed. This paper presents novel algorithms to efficiently predict block boundaries and a runtime system that enables efficient block-level parallel decompression, called SDM. The SDM execution model features speculative pipelining with three stages: Scanner, Decompressor, and Merger. The scanner stage employs a high-confidence prediction algorithm that finds compressed block boundaries without fully decompressing individual blocks. This information is communicated to the parallel decompressor stage in which multiple blocks are decompressed in parallel. The decompressed blocks are merged in order by the merger stage to produce the final output. The SDM runtime is specialized to execute this pipeline correctly and efficiently on resource-constrained embedded platforms. With SDM we effectively parallelize three production-grade variable-length decompression algorithms? zlib, bzip2, and H.264? with maximum speedups of 2.50× and 8.53× (and geometric mean speedups of 1.96× and 4.04×) on 4-core and 36-core embedded platforms, respectively.
