A hierarchical spatial-temporal graph-kernel for high-resolution SAR image change detection

ABSTRACT Effective utilization of structural information is important for high-resolution synthetic aperture radar (SAR) image change detection. For comprehensively utilizing the local and global structures in SAR images, a hierarchical spatial-temporal graph kernel (STGK) method is proposed in this paper for high-resolution SAR image change detection. First, the bi-temporal hierarchical graph models are constructed for extracting the local-global structures in the bi-temporal SAR images. Then, a STGK function, which measures the spatial and temporal similarities between the local-global structures, is constructed for indicating the change levels between the bi-temporal images. Finally, a support vector machine (SVM) is implemented with the STGK function for producing the final change detection results. Experimental results on real GaoFen-3 SAR data sets demonstrate the effectiveness of the proposed method, and prove that the STGK method is capable of detecting changed areas with relatively complex structures.
Exploring the results of college English learning under the perspective of artificial intelligence

Based on the theory of output hypothesis and the perspective of Artificial Intelligence (AI), the purpose of present study is to verify the result of applying Virtual Reality (VR) experiment. A quantitative method has been used. 69 students as an experimental group and 68 as a control group, by random sampled, have participated this quasi-experiment. After half a year, experimental group has obtained better performance than control group in CET (College English Test). T-test shows significant differences in the result of CET total score (t=2.05, p<0.05) and listening (t=2.70, p<0.01) as well as writing (t=2.32, p<0.05) section score. These results suggest that applying VR method brought positive result for college English learning.
Towards a General Framework for Humor Generation from Rated Examples

Many computer systems are becoming increasingly tailored to their users, customizing and optimizing their experience. However, most conversational agents do not follow this trend when it comes to humorous interactions. Instead, they employ pre-written answers regardless of whether the user liked previous similar interactions. While there already exist several computational humor systems that can successfully generate jokes, their joke generation models, parameters or even both are often ﬁxed. In this paper, we propose G OOFER , a general framework for computational humor that learns joke structures and parameterizations from rated example jokes. This framework uses metrical schemas, a new notion we introduce, which are a generalization of several types of other schemas. This new type of schema makes regular schemas compatible with machine learning techniques. We also pro-pose a strategy for identifying useful humor metrics based on humor theory, which can be used as features for the machine learning algorithm. The G OOFER framework uses these novel concepts to construct a pipeline with new components around previous generators. Using a mapping to our previous work on analogy jokes, we show that this framework cannot only generate this type of jokes well, but also ﬁnd the importance of speciﬁc humor metrics for template values. This indicates that it is on the right track towards joke generation systems that can automatically learn new templates and schemas from rated examples. This work thus forms a stepping stone towards creating programs with a sense of humor that is adaptable to the user.
Effect of Supplementation of Acidifiers with Probiotic on Performance of Broiler Chicken

An experiment was conducted to study the effect of supplementation of acidifiers with probiotic on performance and nitrogen retention of broiler chicken. A total of 300 broilers were reared for six weeks with dietary treatments, T0 (control diet), T1 (control plus sodium-diformate at 0.2%), T2 (control plus sodium diformate at 0.2% plus probiotic at 0.02%), T3 (control plus blends of acidifiers at 0.2%), T4 (control plus blends acidifiers at 0.2% plus probiotic at 0.02%). Each treatment consisted of sixty birds with four replicates containing fifteen birds in each replication. The weekly body weight, body weight gain, feed conversion efficiency was found to be better in all treatment groups as compared to control. However, weekly feed consumption, was found to be unaffected. Also, there was increase in dry matter digestibility and nitrogen retention in all treatment groups as compared to control. It was concluded that the suppleemntation of blends of acidifiers at 0.2% in combination with probiotic @ 0.02% improved the growth performance and nutrients utilization of broiler chicken rearing.

Assembly of a young vertebrate Y chromosome reveals convergent signatures of sex chromosome evolution

Heteromorphic sex chromosomes have evolved repeatedly across diverse species. Suppression of recombination between X and Y chromosomes leads to rapid degeneration of the Y chromosome. However, these early stages of degeneration are not well understood, as complete Y chromosome sequence assemblies have only been generated across a handful of taxa with ancient sex chromosomes. Here we describe the assembly of the threespine stickleback (Gasterosteus aculeatus) Y chromosome, which is less than 26 million years old. Our previous work identified that the non-recombining region between the X and the Y spans ∼17.5 Mb on the X chromosome. Here, we combined long-read PacBio sequencing with a Hi-C-based proximity guided assembly to generate a 15.87 Mb assembly of the Y chromosome. Our assembly is concordant with cytogenetic maps and Sanger sequences of over 90 Y chromosome clones from a bacterial artificial chromosome (BAC) library. We found three evolutionary strata on the Y chromosome, consistent with the three inversions identified by our previous cytogenetic analyses. The young threespine stickleback Y shows convergence with older sex chromosomes in the retention of haploinsufficient genes and the accumulation of genes with testis-biased expression, many of which are recent duplicates. However, we found no evidence for large amplicons found in other sex chromosome systems. We also report an excellent candidate for the master sex-determination gene: a translocated copy of Amh (Amhy). Together, our work shows that the same evolutionary forces shaping older sex chromosomes can cause remarkably rapid changes in the overall genetic architecture on young Y chromosomes.
EXERCISE INTERVENTION IN TYPE 2 DIABETES MELLITUS: IMPACT ON CARDIAC DIASTOLIC FUNCTION

We combined the change in E/A ratio with the change of other echographic parameters to determine whether it improved or not, by assigning the change a positive or negative value. BACKGROUND METHODS RESULTS CONCLUSION: Next to reductions in blood HbA1c concentrations exercise training in a fasted state, but not in a fed state, leads to improvements in the echocardiographic E/A ratio (a diastolic parameter) in patients with type 2 diabetes.
Exploring How Beliefs About Algorithms Shape (Offline) Success in Online Dating: A Two-Wave Longitudinal Investigation

Matching algorithms are a central feature of online dating, yet little research exists on their effectiveness—or people’s perceptions of their effectiveness—for recommending a mate. Accordingly, this study explores the effects of people’s beliefs in the legitimacy of algorithms on their first date with an online dating partner. Longitudinal survey data were collected from online dating participants leading up to and following the first date. Findings suggested that whether algorithms actually worked mattered less than whether participants had the perception that they worked for finding a partner. Moreover, participants reported better first dates to the extent that they believed in the efficacy of the compatibility matching process. The results have implications for understanding the role of algorithms in shaping relationship success on and off the internet.
A Low-Voltage Robust Class-C VCO With Dual Digital Feedback Loops

This brief presents a low-supply-voltage robust class-C voltage-controlled oscillator (VCO) with the dual digital feedback loops. One is the digital adaptive bias loop (DABL) which is proposed to ensure startup robustness and improve the phase noise performance of the VCO. And the other is the digital amplitude control loop (DACL), which is adopted to stabilize the oscillation amplitude over process, voltage and temperature (PVT) variations. Moreover, a cooperative algorithm is also proposed in order to make the dual digital loops work properly. Besides, the offset canceling comparators are adopted to guarantee the stability of the digital loops. The proposed VCO is implemented in SMIC 0.18 $\mu \text{m}$ CMOS process, achieving a phase noise of −123.3 dBc/Hz at 1 MHz offset from a 2.55 GHz carrier and a 2.2-2.7 GHz frequency tuning range. The figure-of-merit (FoM) is −190.4 dBc/Hz with the total power consumption less than 1.28 mW at the 0.8 V supply voltage.
SAT0597 Relationship between lumbar disc herniation and benign joint hypermobility syndrome

Background Benign joint hypermobility syndrome (BJHS) can present with a wide variety of musculoskeletal disorders.Benign joint hypermobility syndrome (BJHS) is a hereditary disorder characterized by the presence of musculoskeletal symptoms in persons with generalized joint laxity in the absence of systemic rheumatologic disease (1–3). Lumbar disc herniation (LDH) is a common cause of low back pain. On the other hand, low back pain may be a presenting symptom in patients with BJHS. Objectives to evaluate relationship between Lumbar disc herniation and BJHS. Methods The study included 100 patients diagnosed with LDH depending on history, clinical examination and MRI findings and another 100 healthy control participants. All, patients and healthy controls were assessed for BJHS using the revised (Brighton 1998) criteria. Results the mean age was (35.4±8.9) year and (33.72±8.3) for patients and controls respectively, there were 43 males and 57 females in each group. The mean BMI was (27.6±4.8) kg/m2 in patients and (28.3±4.6) in controls. No significant differences found between the groups regarding the age, sex and BMI in all comparisons (P.value>0.05). The mean Beighton score was significantly higher among patients in comparison to controls; itwas (2.3±1.62) versus (1.2±1.35) in controls group; on the other hand major and minor criteria were significantly more prevalent among patients rather than controls, in all comparisons (P.value<0.05). BJHS was more prevalent among patients rather than controls, 55% of the patients had BJHS compared to 21% of controls, the odds ratio was (4.6) and (P.value <0.05). BJHS was more prevalent among females compared to males, from the total number of all participants, BJHS was present in 76 participants, and of them 47 were females versus 29 males, (P.value <0.05). It had been significantly found that subjects with BJHS in both groups (patients and controls) were relatively shorter than those without BJHS, P.value <0.05. The correlation analysis of BJHS with the MRI findings of LDH in patients group showed no significant differences among patients with and without BJHS, in all comparisons P.value >0.05. Conclusions BJHS is more prevalent among patients with LDH. There is no significant relationship between presence of BJHS in LDH patients and MRI findings. References Hakim AJ, Grahame R.

A New Parametric Adaptive Source Domain Method for Sound Field Synthesis

In this brief, we aim at developing an adaptive method that localizes and traces source positions from acoustic signals received by microphone arrays, which provides valuable source domain information for sound field synthesis. The proposed method explores a sparse representation of the sound pressure measurements that expand an overcomplete source domain. We enforce sparsity by imposing L1 regularization on the cost function. A new adaptive method is then formulated to solve the multiple time and frequency samples. Using the sparse source domain information, the sound field can be synthesized. The mean squares performance analysis of the proposed algorithm is carried out and an automatic selection criterion is introduced for the regularization parameter. Experiments are conducted to examine the effectiveness of the method. It shows that the proposed method has improved performance in terms of resolution, tracking capability, and possible frequency aliasing free effect.
Transport of engineered nanoparticles in porous media and its enhancement for remediation of contaminated groundwater

Abstract The engineered nanoparticles (ENPs) with high reactivity are promising materials for in-situ groundwater remediation, however, their low mobility in natural porous media greatly limits their application in this area. Therefore, understanding the fate and transport of ENPs in subsurface environment and how to enhance the transport is extremely important. This review is focused on recent advances in research on fate and transport of ENPs in porous media, with respect to mechanisms and mathematical models associated with ENPs transport and strategies for transport enhancement. Results of the existing research indicate that main mechanisms associated with ENPs transport include advection, dispersion, adsorption, straining, aggregation, blocking, ripening, and size exclusion, which are affected by a combination of various factors including physicochemical properties of ENPs, porous media and aqueous phase, and the flow conditions as well. In natural soils and sediments, ENPs transport can be enhanced in the presence of polymers or mobile carriers, however, such an enhancement may still not guarantee delivery of ENPs and adequate distribution throughout the contaminated area. For successful ENPs application in groundwater remediation, it is urgent to develop more effective technology to facilitate ENPs transport in subsurface. Graphical Abstract
Prevalence and Determinants of Depression among Qatari Adolescents in Secondary Schools

Adolescence is an important period for the development of a socially integrated self-negative, which may affect future decisions through depression and anxiety. It is estimated that 20% of adolescents have some type of psychological disorder, and the most common disorder is depression. Methodology: A cross sectional descriptive study conducted among Qatari adolescents in secondary Schools in Qatar. Multistage sampling technique was applied, 823qatari adolescent students were approached of which 797 agreed to participate giving a response rate of 96.8 %. Using a self-administered Arabic version of Beck’s Depression Inventory – II (BDI-II) [2], which measures the depression over the last two weeks in adults and adolescents aged 13 years and older. Results: Almost one third of Qatari adolescents in secondary schools have depression 34.5%, Female adolescents were more likely to have depression than male. Bad relationship with peers, parents and teachers were among the most significant predictors of depression (OR=14.0, 95%CI=1.55-124), (OR=9.4, 95%CI=1.04-85.4), (OR=5.0, 95%CI=1.41-18.26) consecutively. Recommendation: Adopting holistic approach in dealing with adolescent’s wellbeing, through incorporating preventive psychological interventions, such as early screening for depressive symptoms, counseling and psychological support should be available to adolescent students with depressive symptoms.
Validation of perineometric and bidigital test findings to predict urinary incontinence occurrence in primigravidas

Hypothesis / aims of study The pelvic floor (PF) plays a leading role in protecting and sustaining pelvic and abdominal organs,as well as in maintaining fecal and urinary continence (1). As pregnancy advances, pelvic floor muscle function (PFMF) decreases due to hormone and biomechanic changes that normally occur during gestation (2). These changes associated with increase in body mass índex, parity and duration of the expulsation phase can weaken pelvic floor muscles, and lead to urinary incontinence (UI) (1). Studies have shown that incontinent women have a significant PFMF deficit in comparison with continent women (1,2). Several techniques have been proposed for the assessment of PFMF, but the bigital test and perineometry are the most commonly used (1). According to the literature, despite being two distinct methods, bidigital test and perineometry correlate positively. However, there is no consensus method for PFMF assessment (3). Both perineometry and bidigital palpation are limited because vaginal pressure normality parameters in pregnant women and the cutoff points predictive of UI during pregnancy have not been so far determined. Thus, the purpose of this study was to validate perineometric and bidigital palpation measurements in primigravidas, and to determine the cutoff point predictive of UI occurrence for both these methods.

Bilateral Subclavian Artery Stenosis: Anaesthetic consideration

Subclavian artery stenosis (SAS) is a relatively rare condition, even more so for its bilateral existence. In a study [1], the prevalence of SAS was 1.9% in the free-living ohorts and 7.1% in the clinical cohorts. SAS was signifi cantly associated with smoking and higher levels of systolic blood pressure.
Résorption condylienne après chirurgie orthognathique : étude rétrospective sur 40 patients au CHU de Caen

La resorption condylienne (RC) correspond a une alteration progressive de la forme et du volume du condyle mandibulaire. Elle se rencontre apres une chirurgie orthognathique, suite aux contraintes exercees sur le condyle lors de l’intervention. Afin de limiter des dernieres, tout en facilitant la correction de l’occlusion en per-operatoire, plusieurs mini-plaques d’osteosynthese ajustables ont ete developpees. Materiel et methode : une etude retrospective, entre janvier 2014 et decembre 2017, a ete realisee dans le service de chirurgie maxillofaciale du CHU de Caen, sur des patients ayant beneficie en chirurgie orthognathique d’une osteosynthese mandibulaire a l’aide de miniplaques en forme de S (OBL®). Le critere de jugement principal etait l’evaluation d’une RC en post-operatoire tardif. Resultats : chez les 40 patients inclus, il est retrouve une baisse significative des craquements mandibulaires en post-operatoire. Seul un patient a montre des signes radiographiques de RC avec une baisse de la hauteur des condyles de plus de 2 mm et une diminution de la hauteur ramique de plus de 6 %. Morphologiquement, les condyles n’ont pas montre de modification notable sur l’analyse du panoramique dentaire. Conclusion : les plaques en S, pratiques et simples d’utilisation, ne semblent pas pourvoyeuses de RC. Une etude plus approfondie avec des donnees scanographiques serait necessaire pour parfaire la precision de ce travail.
Assured Multi-Mode Navigation for Urban Operations of Small UAS

The paper discusses the preliminary analysis of an urban availability tool required for preflight flight planning. In this tool, areas in an urban environment are assessed with respect to GNSS availability, separation to traffic and obstacles, impact of UAS noise, and various other criteria. GNSS availability will drive the necessity to include alternative navigation sensors such as laser scanners, vision sensors and altimeters in the navigation mechanization to meet the required navigation performance necessary for urban operations. This paper shows the initial results of the GNSS availability tool and discusses the sensor integration strategy when GNSS-only availability is not sufficient.
