Context multi-task visual object tracking via guided filter

In this paper, we formulate particle filter based tracking as a multi-task sparse learning problem that exploits context information. The target and context information which modeled as linear combinations of principal component analysis (PCA) basis is formed as dictionary templates. We treat the dictionary templates as the guidance and the incoming candidates are filtered depending on the similarity between the guidance image and each input. The guided filter can help to distinguish the target from numerous candidates via context information. Then multi-task sparse learning is employed to learn the target and context information. The proposed learning problem is efficiently solved using an alternating direction method of multipliers (ADMM) method that yield a sequence of closed form updates. We test our tracker on challenging benchmark sequences that involve drastic illumination changes, large pose variations, and heavy occlusion. Experimental results show that our tracker consistently outperforms state-of-the-art trackers.
Assessment of pulmonary toxicity of MgO nanoparticles in rats

In this study, we have evaluated the pulmonary toxicity of MgO nanoparticles (MgO NPs) in rats following their exposure. NPs in phosphate buffered saline + 1% Tween 80 were exposed via intratracheal instillation at a doses of 1 mg/kg or 5 mg/kg into rat lungs and evaluated for various tissue damage markers like alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in bronchoalveolar lavage (BAL) fluid and histopathology of lungs at 1, 7, and 30 days of post‐exposure intervals. A dose‐dependant increase in ALP and LDH activity was observed in BAL fluids of rat lungs than sham control at all post‐exposure periods (P <0.05), and a dose‐dependant infiltration of interstitial lymphocytes, peribronchiolar lymphocytic infiltration, and dilated and/or congested vessels at 1 day post‐exposure period, worsened at 1 week period, and were reduced at 1 month at histology, indicating the pulmonary toxicity of MgO NPs. In conclusion, MgO NPs exposure produced a dose‐dependent pulmonary toxicity in rats and was comparable with that of Quartz particles. © 2013 Wiley Periodicals, Inc.

Dynamic integrity measurement model based on vTPM

With the development of cloud computing, virtualization technology has been widely used in our life. Meanwhile, it became one of the key targets for some attackers. The integrity measurement in virtual machine has become an urgent problem. Some of the existing virtualization platform integrity measurement mechanism introduces the trusted computing technology, according to a trusted chain that the Trusted Platform Module (TPM) established for trusted root to measure the integrity of process in static. But this single chain static measurement cannot ensure the dynamic credible in platform running. To solve the problem that the virtual trusted platform can not guarantee the dynamic credibility, this paper put forward Dynamic Integrity Measurement Model (DIMM) based on virtual Trusted Platform Module (vTPM) which had been implemented with typical virtual machine monitor Xen as an example. DIMM combined with virtual machine introspection and event capture technology to ensure the security of the entire user domain. Based on the framework, this paper put forward Self-modify dynamic measurement strategy which can effectively reduce the measurement frequency and improve the measurement performance. Finally, it is proved that the validity and feasibility of the proposed model with comparison experiments.
The modified feature subsets ensemble applied for the mach number prediction in wind tunnel

Large-scale and high-dimensional data are the main difficulties for Mach number prediction in a wind tunnel system. To solve these issues, based on the multivariate fuzzy Taylor theorem, the Feature Subsets Ensemble (FSE) method has been proposed. However, data sampled from measurements have noise. The FSE uses the entire data set at least once, and for data with noise this property may reduce the generalization of Mach number prediction. In this paper, a Modified Feature Subsets Ensemble (MFSE) method is proposed to overcome the limitation of the FSE on noisy data by introducing the bootstrap to the feature subsets. The bootstrap has the potential to avoid noise. In addition, the generating procedure of the bootstrap replications is straightforward, simple, and quick, which keeps the complexity of the MFSE low. Experiments show that the MFSE outperforms the FSE and the Random Forest method, particularly on high-noise data sets. For all three working conditions, on both the low- and the high-noise testing sets, only the MFSE estimator meets the requirements of forecasting speed, accuracy, and generalization of Mach number prediction.
Application of a novel prognostic invasive lesion index in ductal carcinoma in situ with minimal invasion of the breast

Multiple invasive foci has been shown to increase the risk of lymph node metastasis (LNM) in early breast cancer, but its prognostic implication remains unknown. We aimed to identify the prognostic value of the number of invasive foci in ductal carcinoma in situ with minimal invasion of the breast (DCIS‐MI), and further establish a prognostic invasive lesion index (ILI). A total of 193 patients with DCIS‐MI (the invasive component was up to 10 mm in diameter) were included. Univariate and multivariate analysis (logistic regression) were used to evaluate the predictive value of the number of invasive foci in LNM. The Kaplan–Meier curve was used for survival analysis. More than five invasive foci was an independent predictor for LNM (OR, 2.67, 95% CI, 1.12–6.33, P = 0.026), and associated with significantly shorter disease‐free survival (DFS) and overall survival (OS) compared with no more than five invasive foci (mean DFS 123.8 vs. 148.0 months, P = 0.002; and mean OS 133.5 vs. 151.4 months, P = 0.025). The ILI was established by the sum scores of the number of invasive foci and the invasive component size, having an optimal cut‐off point of 5.5 scores. The high‐ILI group (ILI >5 scores) had a higher incidence of LNM (23.6% vs. 6.9%) and worse prognosis than the low‐ILI group (ILI ≤5 scores). In conclusion, more than five invasive foci was an independent predictor for LNM and an unfavorable prognostic parameter. The ILI could potentially be used to predict survival prognosis in patients with DCIS‐MI.
Component-centric application-driven framework: towards taming privilege separation in Android

Android is a Linux-based Operating-System (OS), the most prevailing Smartphone among its competitors that attracts attackers, the Malware which performs inter-application communication (IAC) precludes malware scanner. We are proposing Honified, a tool performing on-device access control mechanism to combat these vulnerabilities. Furthermore, Honified will interpose the vulnerable but benign application (app) with the code of reference monitor aka Inline reference monitoring and transforms into Honey-app. Moreover, it is derived from the concept of Honeypot, made for being attacked and compromise the security to lure the attacking application. It lures the attacking application and further it is used to provide the resilient as well as robust access control at Stock Android. Honified uses the concept of In-app reference monitoring aka Inline reference monitoring, it also thwarts the dissemination of private data of the user and prompts the user to uninstall the app to reduce monitoring overhead. Delta Micro-benchmark shows that overall score of work with Honified tool achieved 96.89% that is quite affordable.
The SlCBL10 Calcineurin B-Like Protein Ensures Plant Growth under Salt Stress by Regulating Na+ and Ca2+ Homeostasis1

Tomato CALCINEURIN B-LIKE PROTEIN 10 (SlCBL10) ensures plant growth by regulating proper distribution of Na+ and Ca2+ in the shoot apical meristem and developing organs under salt stress. Characterization of a new tomato (Solanum lycopersicum) T-DNA mutant allowed for the isolation of the CALCINEURIN B-LIKE PROTEIN 10 (SlCBL10) gene whose lack of function was responsible for the severe alterations observed in the shoot apex and reproductive organs under salinity conditions. Physiological studies proved that SlCBL10 gene is required to maintain a proper low Na+/Ca2+ ratio in growing tissues allowing tomato growth under salt stress. Expression analysis of the main responsible genes for Na+ compartmentalization (i.e. Na+/H+ EXCHANGERs, SALT OVERLY SENSITIVE, HIGH-AFFINITY K+ TRANSPORTER 1;2, H+-pyrophosphatase AVP1 [SlAVP1] and V-ATPase [SlVHA-A1]) supported a reduced capacity to accumulate Na+ in Slcbl10 mutant leaves, which resulted in a lower uploading of Na+ from xylem, allowing the toxic ion to reach apex and flowers. Likewise, the tomato CATION EXCHANGER 1 and TWO-PORE CHANNEL 1 (SlTPC1), key genes for Ca2+ fluxes to the vacuole, showed abnormal expression in Slcbl10 plants indicating an impaired Ca2+ release from vacuole. Additionally, complementation assay revealed that SlCBL10 is a true ortholog of the Arabidopsis (Arabidopsis thaliana) CBL10 gene, supporting that the essential function of CBL10 is conserved in Arabidopsis and tomato. Together, the findings obtained in this study provide new insights into the function of SlCBL10 in salt stress tolerance. Thus, it is proposed that SlCBL10 mediates salt tolerance by regulating Na+ and Ca2+ fluxes in the vacuole, cooperating with the vacuolar cation channel SlTPC1 and the two vacuolar H+-pumps, SlAVP1 and SlVHA-A1, which in turn are revealed as potential targets of SlCBL10.
Bilingual infants control their languages as they listen

Significance Bilingual infants must manage two languages in a single developing mind. However, the mechanisms that enable young bilinguals to manage their languages over the course of learning remain unclear. Here, we demonstrate that bilingual infants monitor and control their languages during real-time language listening, and do so similarly to bilingual adults. This ability could help bilinguals’ language learning to keep pace with that of their monolingual peers, and may underpin the cognitive advantages enjoyed by bilinguals in both infancy and adulthood. Infants growing up in bilingual homes learn two languages simultaneously without apparent confusion or delay. However, the mechanisms that support this remarkable achievement remain unclear. Here, we demonstrate that infants use language-control mechanisms to preferentially activate the currently heard language during listening. In a naturalistic eye-tracking procedure, bilingual infants were more accurate at recognizing objects labeled in same-language sentences (“Find the dog! ”) than in switched-language sentences (“Find the chien! ”). Measurements of infants’ pupil size over time indicated that this resulted from increased cognitive load during language switches. However, language switches did not always engender processing difficulties: the switch cost was reduced or eliminated when the switch was from the nondominant to the dominant language, and when it crossed a sentence boundary. Adults showed the same patterns of performance as infants, even though target words were simple and highly familiar. Our results provide striking evidence from infancy to adulthood that bilinguals monitor their languages for efficient comprehension. Everyday practice controlling two languages during listening is likely to explain previously observed bilingual cognitive advantages across the lifespan.
Brachypodium as a Model for the Grasses: Today and the Future1[W]

Over the past several years, Brachypodium distachyon (Brachypodium) has emerged as a tractable model system to study biological questions relevant to the grasses. To place its relevance in the larger context of plant biology, we outline here the expanding adoption of Brachypodium as a model grass and compare this to the early history of another plant model, Arabidopsis thaliana. In this context, Brachypodium has followed an accelerated path in which the development of genomic resources, most notably a whole genome sequence, occurred concurrently with the generation of other experimental tools (e.g. highly efficient transformation and large collections of natural accessions). This update provides a snapshot of available and upcoming Brachypodium resources and an overview of the community including the trajectory of Brachypodium as a model grass.
Microbiologically influenced corrosion monitoring: Real world failures and how to avoid them

Monitoring for microbiologically influenced corrosion in industry commonly is practiced, but too often has failed to predict corrosion damage. Reports of failed manitoring seldom appear in the published literature, but hands-on experience and word-of-mouth communication indicate that the problem is widespread. The question of why so many monitoring programs are unsuccessful is investigated, and remedies for common problems are suggested. Failures can be attributed to three main causes: confusion over the goals of the monitoring program, inappropriate monitoring methods, and inadequate execution of the monitoring program.
Effects of QUV accelerated aging on surface hardness, surface roughness, glossiness, and color difference for some wood species

The surface hardness, surface roughness, glossiness, and color difference were determined for wooden materials produced from three commonly used species - two native of Turkey and one exotic - treated with one- and two-component water-based varnishes and exposed to different amounts of radiation to mimic accelerated aging using a QUV aging device. One- and two-component water-based varnishes were applied two-and three coats to Scoth pine (Pinus sylvestris L.), Iroko (Chlorophora excelsa), and Anatolian chestnut (Castenea sativa Mill.) woods. Then, the varnish coated materials were exposed to QUV aging devices for 216 and 432 h. Results indicated that thesurface hardness and glossiness were decreased for all the three wood species across all the treatment combinations. However, values of surface roughness and color difference were increased for all the three wood species across all the treatment combination. Key words: QUV aging, surface hardness, surface roughness, glossiness, color difference, contact information.
Iterative adaptive method for real-beam scanning imaging

This paper present a novel superresolution algorithm for real-beam scanning radar based on the iterative adaptive strategy. Firstly, we establish the objective function based on the minimum mean-square error (MMSE) criterion, then we build the iterative expression by update the covariance matrix. This algorithm has better superresolution performance than traditional deconvolution method. Simulation results verified the analysis before.
Comprehensive Learning Particle Swarm Optimizer for Constrained Mixed-Variable Optimization Problems

This paper presents an improved particle swarm optimizer (PSO) for solving multimodal optimization problems with problem-specific constraints and mixed variables. The standard PSO is extended by employing a comprehensive learning strategy, different particle updating approaches, and a feasibility-based rule method. The experiment results show the algorithm located the global optima in all tested problems, and even found a better solution than those previously reported in the literature. In some cases, it outperforms other methods in terms of both solution accuracy and computational cost.
Navigating Nuances of Language and Meaning: Challenges of Cross-Language Ethnography Involving Shona Speakers Living With Schizophrenia

For people living with schizophrenia, their experience is personal and culturally bound. Focused ethnography enables researchers to understand people’s experiences in-context, a prerequisite to providing person-centered care. Data are gathered through observational fieldwork and in-depth interviews with cultural informants. Regardless of the culture, ethnographic research involves resolving issues of language, communication, and meaning. This article discusses the challenges faced by a bilingual, primary mental health nurse researcher when investigating the experiences of people living with schizophrenia in Zimbabwe. Bilingual understanding influenced the research questions, translation of a validated survey instrument and interview transcripts, analysis of the nuances of dialect and local idioms, and confirmation of cultural understanding. When the researcher is a bilingual cultural insider, the insights gained can be more nuanced and culturally enriched. In cross-language research, translation issues are especially challenging when it involves people with a mental illness and requires researcher experience, ethical sensitivity, and cultural awareness.
Concurrent temporal channels for auditory processing: Oscillatory neural entrainment reveals segregation of function at different scales

Natural sounds convey perceptually relevant information over multiple timescales, and the necessary extraction of multi-timescale information requires the auditory system to work over distinct ranges. The simplest hypothesis suggests that temporal modulations are encoded in an equivalent manner within a reasonable intermediate range. We show that the human auditory system selectively and preferentially tracks acoustic dynamics concurrently at 2 timescales corresponding to the neurophysiological theta band (4–7 Hz) and gamma band ranges (31–45 Hz) but, contrary to expectation, not at the timescale corresponding to alpha (8–12 Hz), which has also been found to be related to auditory perception. Listeners heard synthetic acoustic stimuli with temporally modulated structures at 3 timescales (approximately 190-, approximately 100-, and approximately 30-ms modulation periods) and identified the stimuli while undergoing magnetoencephalography recording. There was strong intertrial phase coherence in the theta band for stimuli of all modulation rates and in the gamma band for stimuli with corresponding modulation rates. The alpha band did not respond in a similar manner. Classification analyses also revealed that oscillatory phase reliably tracked temporal dynamics but not equivalently across rates. Finally, mutual information analyses quantifying the relation between phase and cochlear-scaled correlations also showed preferential processing in 2 distinct regimes, with the alpha range again yielding different patterns. The results support the hypothesis that the human auditory system employs (at least) a 2-timescale processing mode, in which lower and higher perceptual sampling scales are segregated by an intermediate temporal regime in the alpha band that likely reflects different underlying computations.
Constructing arguments from multiple sources: Tasks that promote understanding and not just memory for text.

In 2 experiments, understanding of historical subject matter was enhanced when students acted as historians and constructed their own models of an historical event. Providing students with information in a web site with multiple sources instead of a textbook chapter, and instructing them to write arguments instead of narratives, summaries, or explanations, produced the most integrated and causal essays with the most transformation from the original sources. Better performance on inference and analogy tasks provided converging evidence that students who wrote arguments from the web sources gained a better understanding than other students. A second experiment replicated the advantage of argument writing even when information was presented as an argument.
Image Mosaicking Approach for a Double-Camera System in the GaoFen2 Optical Remote Sensing Satellite Based on the Big Virtual Camera

The linear array push broom imaging mode is widely used for high resolution optical satellites (HROS). Using double-cameras attached by a high-rigidity support along with push broom imaging is one method to enlarge the field of view while ensuring high resolution. High accuracy image mosaicking is the key factor of the geometrical quality of complete stitched satellite imagery. This paper proposes a high accuracy image mosaicking approach based on the big virtual camera (BVC) in the double-camera system on the GaoFen2 optical remote sensing satellite (GF2). A big virtual camera can be built according to the rigorous imaging model of a single camera; then, each single image strip obtained by each TDI-CCD detector can be re-projected to the virtual detector of the big virtual camera coordinate system using forward-projection and backward-projection to obtain the corresponding single virtual image. After an on-orbit calibration and relative orientation, the complete final virtual image can be obtained by stitching the single virtual images together based on their coordinate information on the big virtual detector image plane. The paper subtly uses the concept of the big virtual camera to obtain a stitched image and the corresponding high accuracy rational function model (RFM) for concurrent post processing. Experiments verified that the proposed method can achieve seamless mosaicking while maintaining the geometric accuracy.
Effects of a population-based, person-centred and integrated care service on health, wellbeing and self-management of community-living older adults: A randomised controlled trial on Embrace

Objective To evaluate the effects of the population-based, person-centred and integrated care service ‘Embrace’ at twelve months on three domains comprising health, wellbeing and self-management among community-living older people. Methods Embrace supports older adults to age in place. A multidisciplinary team provides care and support, with intensity depending on the older adults’ risk profile. A randomised controlled trial was conducted in fifteen general practices in the Netherlands. Older adults (≥75 years) were included and stratified into three risk profiles: Robust, Frail and Complex care needs, and randomised to Embrace or care as usual (CAU). Outcomes were recorded in three domains. The EuroQol-5D-3L and visual analogue scale, INTERMED for the Elderly Self-Assessment, Groningen Frailty Indicator and Katz-15 were used for the domain ‘Health. ’ The Groningen Well-being Indicator and two quality of life questions measured ‘Wellbeing. ’ The Self-Management Ability Scale and Partners in Health scale for older adults (PIH-OA) were used for ‘Self-management. ’ Primary and secondary outcome measurements differed per risk profile. Data were analysed with multilevel mixed-model techniques using intention-to-treat and complete case analyses, for the whole sample and per risk profile. Results 1456 eligible older adults participated (49%) and were randomized to Embrace (n(T0) = 747, n(T1) = 570, mean age 80.6 years (SD 4.5), 54.2% female) and CAU (n(T0) = 709, n(T1) = 561, mean age 80.8 years (SD 4.7), 55.6% female). Embrace participants showed a greater–but clinically irrelevant–improvement in self-management (PIH-OA Knowledge subscale effect size [ES] = 0.14), and a greater–but clinically relevant–deterioration in health (ADL ES = 0.10; physical ADL ES = 0.13) compared to CAU. No differences in change in wellbeing were observed. This picture was also found in the risk profiles. Complete case analyses showed comparable results. Conclusions This study found no clear benefits to receiving person-centred and integrated care for twelve months for the domains of health, wellbeing and self-management in community-living older adults.
