DeepID-Net: Object Detection with Deformable Part Based Convolutional Neural Networks

In this paper, we propose deformable deep convolutional neural networks for generic object detection. This new deep learning object detection framework has innovations in multiple aspects. In the proposed new deep architecture, a new deformation constrained pooling (def-pooling) layer models the deformation of object parts with geometric constraint and penalty. A new pre-training strategy is proposed to learn feature representations more suitable for the object detection task and with good generalization capability. By changing the net structures, training strategies, adding and removing some key components in the detection pipeline, a set of models with large diversity are obtained, which significantly improves the effectiveness of model averaging. The proposed approach improves the mean averaged precision obtained by RCNN <xref ref-type="bibr" rid="ref1">[1]</xref> , which was the state-of-the-art, from <inline-formula><tex-math notation="LaTeX">$31$</tex-math><alternatives> <inline-graphic xlink:href="ouyang-ieq1-2587642.gif"/></alternatives></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$50.3$</tex-math><alternatives><inline-graphic xlink:href="ouyang-ieq2-2587642.gif"/> </alternatives></inline-formula> percent on the ILSVRC2014 detection test set. It also outperforms the winner of ILSVRC2014, GoogLeNet, by 6.1 percent. Detailed component-wise analysis is also provided through extensive experimental evaluation, which provides a global view for people to understand the deep learning object detection pipeline.
Interpreting a case of Japanese phonological alexia: the key is in phonology

A Japanese patient displayed a striking phonological alexia after a lefthemisphere CVA: KT's accuracy in reading real kanji or kana words was essentially normal; but asked to read simple 2-3-character kana strings with orthographically and phonologically unfamiliar form (nonwords), on which normal Japanese readers easily score 100%, he consistently failed to produce a single correct response. The introduction of phonological familiarity (i.e. creating nonwords homophonic with real words) produced a dramatic facilitation of KT's nonword reading, and this marked “;pseudohomophone” effect furthermore interacted with both frequency and concreteness of the words whose pronunciations were mimicked in the nonwords. KT also showed prominent deficits and lexicality effects in phonological tasks such as segmentation and blending that involve no orthographic processing. His pattern of language and reading performance is interpreted as a deficit in which pathologically reduced activation of phonological representatio.
Spaceflight Results in Formation of Defective Bone 1

Abstract Growing rats were flown on 19 day spaceflights aboard Cosmos 782 and 936 biosatellites. Spaceflight resulted in a prominent skeletal defect at the periosteal surface of the tibia diaphysis. The defect, termed an arrest line, was approximately 3 μm across and separated the bone formed in space from that formed following spaceflight. The bone matrix at the arrest line region was abnormal in that collagen fibers were preferentially orientated parallel to the periosteal surface. In addition, the bone matrix was hypomineralized. The altered bone was inferior to normal bone in resistance to abrasion and may be partially responsible for the decrease in torsiona strength observed after spaceflight
Long Work Hours and Family Life

Work-family conflict is a pressing research and policy issue. The authors extend previous scholarship on this issue by studying elite employees’worries about the effects of longwork hours on those in their personal life. This issue is researched cross-nationally in a sample of managers and professionals based in the United States, London, and Hong Kong, all of whom work for one division of a high-commitment, global, financial services firm. Hong Kong respondents are more likely than those in the United States and in England to worry about work-family conflict when controlling for job and family characteristics. The authors argue that the meaning of family varies by national context, in part because of the emphasis in Hong Kong on the extended family as a robust institution with intense ties and obligations. In all three countries, women experience higher levels of work-family conflict than men do.
Inference in Perturbation Models, Finite Mixtures and Scan Statistics: The Volume-of-Tube Formula

This research creates a general class of "perturbation models" which are described by an underlying "null" model that accounts for most of the structure in data and a perturbation that accounts for possible small localized departures. The perturbation models encompass finite mixture models and spatial scan process. In this article, (1) we propose a new test statistic to detect the presence of perturbation, including the case where the null model contains a set of nuisance parameters, and show that it is equivalent to the likelihood ratio test; (2) we establish that the asymptotic distribution of the test statistic is equivalent to the supremum of a Gaussian random field over a high-dimensional manifold (e.g., curve, surface etc.) with boundaries and singularities; (3) we derive a technique for approximating the quantiles of the test statistic using the Hotelling-Weyl-Naiman "volume-of-tube formula"; and (4) we solve the long-pending problem of testing for the order of a mixture model; in particular, derive the asymptotic null distribution for a general family of mixture models including the multivariate mixtures. The inferential theory developed in this article is applicable for a class of non-regular statistical problems involving loss of identifiability or when some of the parameters are on the boundary of the parametric space.
Effectiveness of and Financial Returns to Voluntary Medical Male Circumcision for HIV Prevention in South Africa: An Incremental Cost-Effectiveness Analysis

Background Empirical studies and population-level policy simulations show the importance of voluntary medical male circumcision (VMMC) in generalized epidemics. This paper complements available scenario-based studies (projecting costs and outcomes over some policy period, typically spanning decades) by adopting an incremental approach—analyzing the expected consequences of circumcising one male individual with specific characteristics in a specific year. This approach yields more precise estimates of VMMC’s cost-effectiveness and identifies the outcomes of current investments in VMMC (e.g., within a fiscal budget period) rather than of investments spread over the entire policy period. Methods/Findings The model has three components. We adapted the ASSA2008 model, a demographic and epidemiological model of the HIV epidemic in South Africa, to analyze the impact of one VMMC on HIV incidence over time and across the population. A costing module tracked the costs of VMMC and the resulting financial savings owing to reduced HIV incidence over time. Then, we used several financial indicators to assess the cost-effectiveness of and financial return on investments in VMMC. One circumcision of a young man up to age 20 prevents on average over 0.2 HIV infections, but this effect declines steeply with age, e.g., to 0.08 by age 30. Net financial savings from one VMMC at age 20 are estimated at US$617 at a discount rate of 5% and are lower for circumcisions both at younger ages (because the savings occur later and are discounted more) and at older ages (because male circumcision becomes less effective). Investments in male circumcision carry a financial rate of return of up to 14.5% (for circumcisions at age 20). The cost of a male circumcision is refinanced fastest, after 13 y, for circumcisions at ages 20 to 25. Principal limitations of the analysis arise from the long time (decades) over which the effects of VMMC unfold—the results are therefore sensitive to the discount rate applied, and more generally to the future course of the epidemic and of HIV/AIDS-related policies pursued by the government. Conclusions VMMC in South Africa is highly effective in reducing both HIV incidence and the financial costs of the HIV response. The return on investment is highest if males are circumcised between ages 20 and 25, but this return on investment declines steeply with age.
Biography Dr Lihong Wang earned his Ph . D . degree at Rice

Contrast M elopment of life science for more than three centuries. However, due to strong optical scattering in tissue, its in vivo imaging ability has been restricted to studies at superficial depths. Advances in photoacoustic tomography (PAT) now allow multiscale imaging at depths from sub‐millimeter to several centimeters, with spatial resolutions from sub‐micrometer to sub‐millimeter. Because of this high scalability and its unique optical absorption contrast, PAT is capable of performing anatomical, functional, molecular and fluid‐dynamic imaging at various system levels, and is playing an increasingly important role in fundamental biological research and clinical practice. This review discusses recent technical progress in PAT and presents corresponding applications. It ends with a discussion of several prospects and their technical challenges.

Mental health needs in schools for emotional, behavioural and social difficulties

Within the UK, around 10% of children have mental health problems, but this is likely to be higher among certain specific populations. Children and young people attending provisions for social, emotional and behavioural difficulties (SEBD) are a particularly vulnerable group whose mental health needs are under-researched. The authors, Latha Hackett, Louise Theodosiou, Freya Spicer and Rachel Lever of the Winnicott Centre, Manchester, Claire Blackburn who is a clinical psychologist and Caroline Bond of Manchester University conducted a study which involved all pupils in two schools for children with SEBD. The views of parents and teachers were sought for a sample of 71 children. The Strength and Difficulties Questionnaire and a supplementary questionnaire were used to gain a broad picture of the mental health needs of this group and the services required. The findings from these questionnaires indicate a much higher than national level of perceived mental health difficulties within this population. This piece of research highlights that both teachers and parents identified a need for professional support, from education, social care, health and other services. These findings have implications for future commissioning of services.
MANTRA: A Scalable Approach to Mining Temporally Anomalous Sub-trajectories

In this paper, we study the problem of mining temporally anomalous sub-trajectory patterns from an input trajectory in a scalable manner. Given the prevailing road conditions, a sub-trajectory is temporally anomalous if its travel time deviates significantly from the expected time. Mining these patterns requires us to delve into the sub-trajectory space, which is not scalable for real-time analytics. To overcome this scalability challenge, we design a technique called MANTRA. We study the properties unique to anomalous sub-trajectories and utilize them in MANTRA to iteratively refine the search space into a disjoint set of sub-trajectory islands. The expensive enumeration of all possible sub-trajectories is performed only on the islands to compute the answer set of maximal anomalous sub-trajectories. Extensive experiments on both real and synthetic datasets establish MANTRA as more than 3 orders of magnitude faster than baseline techniques. Moreover, through trajectory classification and segmentation, we demonstrate that the proposed model conforms to human intuition.
Structural Neuroimaging and the Antisocial Brain

A series of neuroimaging studies have reported structural differences in several subcortical and frontal systems in individuals with stable antisocial behavior (sASB). Specifically, differences have been observed in the prefrontal and temporal cortices (e.g., amygdala and hippocampus). However, the sASB population is typically characterized by co-occurring hyperactivity— inattention symptoms and low cognitive ability. These nuisance variables are likely to complicate the interpretation of findings regarding structural differences associated with sASB. The way in which each study deals with these variables influences the conclusions that can be drawn about the brain structure and function of children and adults with sASB. This article briefly reviews the extant literature in this field before considering two approaches that may be used to deal with comorbidities conceptualized as nuisance variables--namely, the analysis of covariance (ANCOVA) and the matched-group design. Then, the authors illustrate, with their own data, checks that may be performed to ensure the validity of results using ANCOVA.
Mapping and molecular cloning of the phn (psiD) locus for phosphonate utilization in Escherichia coli

The Escherichia coli phn (psiD) locus encodes genes for phosphonate (Pn) utilization, for phn (psiD) mutations abolish the ability to use as a sole P source a Pn with a substituted C-2 or unsubstituted hydrocarbon group such as 2-aminoethylphosphonate (AEPn) or methylphosphonate (MPn), respectively. Even though the E. coli K-12 phosphate starvation-inducible (psi) phn (psiD) gene(s) shows normal phosphate (Pi) control, Pn utilization is cryptic in E. coli K-12, as well as in several members of the E. coli reference (ECOR) collection which are closely related to K-12. For these bacteria, an activating mutation near the phn (psiD) gene is necessary for growth on a Pn as the sole P source. Most E. coli strains, including E. coli B, are naturally Phn+; a few E. coli strains are Phn- and are deleted for phn DNA sequences. The Phn+ phn(EcoB) DNA was molecularly cloned by using the mini-Mu in vivo cloning procedure and complementation of an E. coli K-12 delta phn mutant. The phn(EcoB) DNA hybridized to overlapping lambda clones in the E. coli K-12 gene library (Y. Kohara, K. Akiyama, and K. Isono, Cell 50:495-508, 1987) which contain the 93-min region, thus showing that the phn (psiD) locus was itself cloned and verifying our genetic data on its map location. The cryptic phn(EcoK) DNA has an additional 100 base pairs that is absent in the naturally Phn+ phn(EcoB) sequence. However, no gross structural change was detected in independent Phn+ phn(EcoK) mutants that have activating mutations near the phn locus.
On Using a Theory of Knowledge Acquisition to Acquire Knowledge

sense principles. This allowed many phenomena that had been interpreted in terms of very complex theories to be easily understood. Like Kruglanski's, that approach was applied to a very diverse set of phenomena. In 1974, however, very little was known about the cognitive processes underlying the use of social information. The value of that work, when considered in the context of our current understanding of such issues, is very limited. Now, Kruglanski has both a similar objective and a similar approach. He also has, however, 15 years of research and theory in social information processing to use in explicating and refining his formulation. We encourage him to take advantage of this work as his theorizing progresses.
Smart micro Grid power with wireless communication architecture

Since the term Smart Grid has become an extensively used word in the operation of electric power systems and since intermittent renewable energy sources had been and will be massively integrated in electrical grids, it became mandatory to think about smarter communication methods to make the power grid more flexible and robust. In order to address this issue, this paper presents a simplified energy flow average models for hybrid PV/Wind/Battery Micro Grid. Two cases of operation are described in this paper; On-Grid and Off-Grid systems with wireless communication networks architecture simulated using Matlab Simulink. Such models help modeling and sizing Micro Grid systems. The simulation results prove the indispensability of the wireless network communication component on the energy control and management in the Smart Grid power in the isolated sites where wired connection is difficult.
Photonic Structures in Biology: A Possible Blueprint for Nanotechnology

Nature has had millions of years to optimize photonic crystals - an endeavour mankind only really began in the 1980s. Often, we attempt to mimic and expand upon nature's designs in creating photonic structures that meet our technology-driven needs. While this strategy can be fruitful in fabricating novel architectures, one has to keep in mind that nature designed and optimized these structures for specific applications (e.g., colouration, camouflaging, signalling), but certainly not for use in photonic chips and optical circuits. To take full advantage of biological structures as blueprints for nanotechnology, it is important to understand the purpose and development of natural structural colours. In this review, we will discuss important aspects of the design, formation and evolution of the structures embedded in beetle exoskeletons that are responsible for their striking colouration. In particular, we will focus on the purpose of structural colours for camouflaging, mimicry and signalling. We will discuss their evolutionary and ecological development and compare the development of beetles with and without structural colours. Examples of non-colour-related structural functionalities will also be introduced and briefly discussed. Finally, a brief overview of nature's synthesis strategies for these highly evolved structures will be given, with particular focus on membrane assembly.
Semantic Parsing of Large-Scale Indoor Spaces

In this paper, we propose a method for semantic parsing of the 3D point cloud of an entire building using a hierarchical approach: first, the raw data is parsed into semantically meaningful spaces (e.g. rooms, etc) that are aligned into a canonical reference coordinate system. Second, the spaces are parsed into their structural and building elements (e.g. walls, columns, etc). Performing these with a strong notion of global 3D space is the backbone of our method. The alignment in the first step injects strong 3D priors from the canonical coordinate system into the second step for discovering elements. This allows diverse challenging scenarios as man-made indoor spaces often show recurrent regularities while the appearance features can change drastically. We also argue that identification of structural elements in indoor spaces is essentially a detection problem, rather than segmentation which is commonly used. We evaluated our method on a new dataset of several buildings with a covered area of over 6, 000m and over 215 million points, demonstrating robust results readily useful for practical applications.
Anatomic and Biomechanical Comparison of Traditional Bankart Repair With Bone Tunnels and Bankart Repair Utilizing Suture Anchors

Background: Traditional Bankart repair using bone tunnels has a reported failure rate between 0% and 5% in long-term studies. Arthroscopic Bankart repair using suture anchors has become more popular; however, reported failure rates have been cited between 4% and 18%. There have been no satisfactory explanations for the differences in these outcomes. Hypothesis: Bone tunnels will provide increased coverage of the native labral footprint and demonstrate greater load to failure and stiffness and decreased cyclic displacement in biomechanical testing. Study Design: Controlled laboratory study. Methods: Twenty-two fresh-frozen cadaveric shoulders were used. For footprint analysis, the labral footprint area was marked and measured using a Microscribe technique in 6 specimens. A 3-suture anchor repair was performed, and the area of the uncovered footprint was measured. This was repeated with traditional bone tunnel repair. For the biomechanical analysis, 8 paired specimens were randomly assigned to bone tunnel or suture anchor repair with the contralateral specimen assigned to the other technique. Each specimen underwent cyclic loading (5-25 N, 1 Hz, 100 cycles) and load to failure (15 mm/min). Displacement was measured using a digitized video recording system. Results: Bankart repair with bone tunnels provided significantly more coverage of the native labral footprint than repair with suture anchors (100% vs 27%, P < .001). Repair with bone tunnels (21.9 ± 8.7 N/mm) showed significantly greater stiffness than suture anchor repair (17.1 ± 3.5 N/mm, P = .032). Mean load to failure and gap formation after cyclic loading were not statistically different between bone tunnel (259 ± 76.8 N, 0.209 ± 0.064 mm) and suture anchor repairs (221.5 ± 59.0 N [P = .071], 0.161 ± 0.51 mm [P = .100]). Conclusion: Bankart repair with bone tunnels completely covered the footprint anatomy while suture anchor repair covered less than 30% of the native footprint. Repair using bone tunnels resulted in significantly greater stiffness than repair with suture anchors. Load to failure and gap formation were not significantly different.
OPTIMAL LINEAR FILTERING WITH STATE AND OBSERVATION DELAYS

Abstract In this paper, the optimal filtering problem for linear systems with state and observation delays is treated proceeding from the general expression for the stochastic Ito differential of the optimal estimate, error variance, and various error covariances. As a result, the optimal estimate equation similar to the traditional Kalman-Bucy one is derived; however, the resulting system of equations for determining the filter gain matrix consists, in the general case, of an infinite set of equations. It is then demonstrated that a finite set of the filtering equations, whose number is specified by the ratio between the current filtering horizon and the delay values, can be obtained in the particular case of equal or commensurable delays in the observation and state equations. In the example, performance of the designed optimal filter for linear systems with state and observation delays is verified against the best Kalman-Bucy filter available for linear systems without delays.
Ontology Integration Experienced on Medical Terminologies

To build a common controlled vocabulary is a formidable challenge in Medical Informatics. Due to vast scale and multiplicity in interpretation of medical data, it is natural to face overlapping terminologies in the process of tracing medical informatics [40]. A major concern lies in the integration of seemingly overlapping terminologies in the medical domain and this issue has not been well addressed. In this paper, we describe a novel approach for medical ontology integration that relies on the theory of Algorithmic Semantic Refinement we previously developed. Our approach simplifies the task of matching pairs of corresponding concepts derived from a pair of ontology, which is very vital to terminology mapping. A formal theory and algorithm for our approach is devised and the application of this method to two medical terminologies is developed. The result of our work is an integrated medical terminology and a methodology and implementation ready to use for other ontology integration tasks.
