Multisite Calibration Tracking for FY-3A MERSI Solar Bands

The MEdium-Resolution Spectral Imager (MERSI), onboard the second-generation Chinese polar-orbit meteorological satellite FY-3A, is a MODIS-like sensor with 19 solar bands and one thermal infrared band. Although there is a visible onboard calibration device, it can only be used for tracking temporal instrument degradation. The vicarious calibration (VC) campaign at the Dunhuang site, conducted once a year, has been the main postlaunch absolute radiometric calibration method for MERSI in the solar bands. To increase the in-flight calibration frequency, a multisite radiometric calibration tracking method is presented. This method relies on simulated radiation over several stable sites, and a daily calibration updating model is built from long-term trending of calibration coefficient series. The MERSI calibration reference is evaluated against the observations of Aqua MODIS, showing mean relative biases within 5% from 0.4 to 2.1 μm . The short-wave channels of MERSI are found to experience large degradation, particularly the 412-nm band with an annual degradation rate of 9.7%, whereas the red and near-infrared bands are relatively stable with annual degradation rates within ±1%. Several approaches have been used to analyze the reliability of MERSI calibration results. A comparison of the calibration slopes shows that the relative biases between the multisite method and the annual Dunhuang VC campaign are below 3.8%. Aqua MODIS is used as a reference to monitor the data quality of the recalibrated MERSI. A double-difference analysis shows that the mean relative biases are almost within 5% over stable deserts, and the synchronous nadir observation analysis also reveals good agreement.
Chandra and XMM-Newton observations of Tololo 0109-383

We present and discuss Chandra and XMM-Newton observations of the Seyfert 2 galaxy and Compton-thick absorbed source, Tololo 0109-383. The hard X-ray emission (i.e. above ∼2 keV), is dominated by a spatially unresolved reflection component, as already discovered by previous ASCA and BeppoSAX observations. The soft X-ray emission is partly (∼15%) extended over about 1 kpc. Below 2 keV, the spectrum is very steep and two emission lines, probably due to recombination to He-like ions of oxygen and neon, are clearly present. Combining X-rays and optical information taken from the literature, we propose an overall scenario for the nuclear regions of this source.
Scaling Law and Reduced Models for Epitaxially Strained Crystalline Films

A variational model for the epitaxial deposition of a film on a rigid substrate in the presence of a crystallographic misfit is studied. The scaling behavior of the minimal energy in terms of the volume of the film and the amplitude of the misfit is considered, and reduced models in the various regimes are derived by $\Gamma$-convergence methods. Depending on the relation between the thickness of the film and the amplitude of the misfit, the surface or the elastic energy contribution dominates, and in the critical case the two contributions balance. In particular, the formation of islands is proven if the amplitude of the misfit is large compared to the volume of the film.
Antisecretory Action of the Extract of the Aerial Parts of Eremomastax speciosa (Acanthaceae) Occurs through Antihistaminic and Anticholinergic Pathways

Objective. The objective of this study was to find out the possible antiulcer mechanism of action of Eremomastax speciosa. Method. Carbachol- and histamine-induced hypersecretion, associated with the pylorus ligation technique, were used in rats. Gastric mucosal ulceration, mucus production, pH, gastric volume, and acidity were measured. Results. Histamine and carbachol raised gastric acidity to 86.50 and 84.80 mEq/L, respectively, in the control rats, and the extracts (200 mg/kg) reduced gastric acidity to 34.60 and 39.00 mEq/L, respectively. Intraduodenal aqueous extract (400 mg/kg) in histamine- and carbachol-treated rats produced significant (P < 0.001) decreases in acid secretion to 28.50 and 28.80 mEq/L, respectively, and 100 percent inhibition of gastric ulceration. Augmented histamine-induced gastric acid secretion (90.20 mEq/L) was significantly reduced to 52.60 and 27.50 mEq/L by the 200 and 400 mg/kg doses of the aqueous extract, respectively. The extract significantly reduced (P < 0.001) the volume of gastric secretion and significantly increased mucus production. The ulcer inhibition potential of the extract significantly dropped to 25–44% (oral extract) and to 29–37% (duodenal extract) in carbachol/indomethacin-treated rats. Conclusion. The aqueous extract of E. speciosa has both cytoprotective and antisecretory effects. The antisecretory effect may involve a mechanism common to both cholinergic and histaminergic pathways.
Phenotypic Switch in Blood: Effects of Pro-Inflammatory Cytokines on Breast Cancer Cell Aggregation and Adhesion

Hematogeneous metastasis can occur via a cascade of circulating tumor cell adhesion events to the endothelial lining of the vasculature, i.e. the metastatic cascade. Interestingly, the pro-inflammatory cytokines IL-6 and TNF-α, which play an important role in potentiating the inflammatory cascade, are significantly elevated in metastatic breast cancer (BCa) patients. Despite their high metastatic potential, human breast carcinoma cells MDA-MB-231 lack interactions with E-selectin functionalized surfaces under physiological shear stresses. We hypothesized that human plasma, 3-D tumor spheroid culture, and cytokine-supplemented culture media could induce a phenotypic switch that allows BCa cells to interact with E-selectin coated surfaces under physiological flow. Flow cytometry, immunofluorescence imaging, and flow-based cell adhesion assay were utilized to investigate the phenotypic changes of MDA-MB-231 cells with various treatments. Our results indicate that plasma, IL-6, and TNF-α promote breast cancer cell growth as aggregates and induce adhesive recruitment of BCa cells on E-selectin coated surfaces under flow. 3-D tumor spheroid culture exhibits the most significant increases in the interactions between BCa and E-selectin coated surfaces by upregulating CD44V4 and sLex expression. Furthermore, we show that IL-6 and TNF-α concentrations in blood may regulate the recruitment of BCa cells to the inflamed endothelium. Finally, we propose a mechanism that could explain the invasiveness of ‘triple-negative’ breast cancer cell line MDA-MB-231 via a positive feedback loop of IL-6 secretion and maintenance. Taken together, our results suggest that therapeutic approaches targeting cytokine receptors and adhesion molecules on cancer cells may potentially reduce metastatic load and improve current cancer treatments.
How Does the Audience Respond to Constructive Journalism?

The various practices of constructive journalism have the common objective to achieve certain effects on the audience: on the micro-level, the users’ information and emotion, on the meso-level the loyalty towards a media company, and on the macro-level the progress of society. Taking a holistic definition of constructive journalism as a basis, the two experiments discussed in this article examined the audience responses to German-language news and features presented to readers and radio listeners in both constructive and non-constructive versions. The results are multifaceted. On the micro-level, constructive forms can counteract a negative view of the world because the audience recognises a solution-orientation and underlying spirit of hope. The increased willingness to share constructive stories indicates, on the macro-level, that constructive reporting can raise the perception of possible solutions and role models and hence encourage engagement and emulation. But the hopeful prospects should not be used to simply garnish a difficult problem at any price and maintaining a distance from positive examples is advisable—otherwise, the constructive story runs the risk of being perceived as a commercial or political influence.
Dissociating State and Item Components of Recognition Memory Using fMRI

Cognitive functions such as memory retrieval involve a combination of state- and item-related processes. State-related processes are sustained throughout a task (e.g., "retrieval mode" associated with ongoing goals), whereas item-related processes are transient and allied to individual stimuli (e.g., "retrieval success" associated with the recovery of information from memory). The present study employed a mixed "blocked and event-related" experimental design to identify neural mechanisms that support state- and item-related processes during a recognition memory task. Subjects alternated between blocks of fixation and recognition memory (discriminating between old and new words). Critically, event-related procedures were embedded within the recognition blocks, including the jittering of sequential trials. This design ensures that the temporal profiles of state- and item-related activity differ and consequently renders them separable; without this procedure item-related activity would summate to produce a state-like response. Results suggest three classes of brain region support recognition memory, exhibiting: (1) predominantly transient activity (including regions in medial parietal, lateral parietal, and anterior left frontal cortex) reflecting item-related processing associated with "retrieval success," (2) predominantly sustained activity (including decreased activity in bilateral parahippocampal cortex) reflecting state-related processing associated with "retrieval mode," (3) concurrent sustained and transient activity (including regions in left middle frontal gyrus, bilateral frontal operculum, and medial frontal gyrus), reflecting a combination of state- and item-related processing. The present findings support the idea that recognition memory tasks are dependent upon a combination of state- and item-related processes that have dissociable neural correlates identifiable using fMRI. Moreover, the mixed "blocked and event-related" design employed here provides a general procedure for separating state- and item-related processes.
Comparing parent and teacher ratings of emotional and behavioural difficulties in 5-year old children who are deaf or hard-of-hearing

ABSTRACT Children who are deaf or hard of hearing (DHH) are at higher risk of developing mental health problems. This study reports on the parent and teacher ratings of emotional and behavioural difficulties (EBD) in 5-year old DHH children. It explores the similarities and differences between informants, and the risk and protective factors associated with parent and teacher-ratings of EBD. Parents and teachers of 224 DHH children completed questionnaires on children's EBD and functional auditory behaviour. Children completed standardized assessments of non-verbal cognitive and language abilities. On average, parent- and teacher-rated EBD were 0.42 and 0.20 standard deviations higher than typically developing children. Parents reported more behavioural problems (hyperactivity and conduct), whereas teachers reported poorer prosocial behaviour. Inter-rater correlations were generally low to moderate (0.29 to 0.50). Overall, children with additional disabilities, lower non-verbal cognitive ability, and poor functional auditory behaviour were at higher risk of EBD. Language ability was only a significant predictor of teacher-rated EBD for children with hearing aids but not cochlear implants. Differences in informant-ratings emphasize the need for a multi-informant approach to get a global perspective on the psychopathology of DHH children. The findings indicate that parents may need assistance with managing behavioural problems at home, and teachers should facilitate more opportunities to practice prosocial behaviour at school. Intervention efforts should focus on facilitating good functional listening skills, as this may in turn, improve the mental health of young DHH children.
Education intervention using para-sports for athletes with high support needs to improve attitudes towards students with disabilities in Physical Education

ABSTRACT In this research, para-sports for athletes with high support needs are used to sensitise students towards disability in their Physical Education (PE) classes, aiming to: 1) explore the participants’ attitudes towards disability and their previous contact with individuals with disabilities; and 2) know the short- and long-term effects of a Para-Sports Awareness Programme (PSAP) on attitudes towards disability. Totally, 88 participants in the sixth-grade of Spanish Primary Schools were divided into a control group (15 males, 30 females; mean age = 11.29, SD = .51), and an intervention group (20 males, 23 females; mean age = 11.51, SD = .59). The PSAP developed is based on boccia and goalball, including an education intervention in natural settings, comprising information, multimedia material and the simulation of physical and visual impairments. A questionnaire based on the Theory of Planned Behaviour and a Spanish version of the Children’s Attitudes towards Integrated PE (CAIPE) questionnaire were used to assess students’ attitudes towards disabilities in PE classes. After the PSAP, the intervention group demonstrated improved attitudes in all variables, with some statistically significant differences, such as concerning the acceptance of adaptations in sports practice (p < .01; d = .58). Therefore, the intervention proves the effectiveness of the applied PSAP in improving students’ attitudes towards disabilities.
Sequential Monte Carlo Optimization Using Artificial State-Space Models

We introduce a method for sequential minimization of a certain class of (possibly non-convex) cost functions with respect to a high dimensional signal of interest. The proposed approach involves the transformation of the optimization problem into one of estimation in a discrete-time dynamical system. In particular, we describe a methodology for constructing an artificial state-space model which has the signal of interest as its unobserved dynamic state. The model is "adapted" to the cost function in the sense that the maximum a posteriori (MAP) estimate of the system state is also a global minimizer of the cost function. The advantage of the estimation framework is that we can draw from a pool of sequential Monte Carlo methods, for particle approximation of probability measures in dynamic systems, that enable the numerical computation of MAP estimates. We provide examples of how to apply the proposed methodology, including some illustrative simulation results.
Slow components of axonal transport: two cytoskeletal networks

We have identified two slowly moving groups of axonally transported proteins in guinea pig retinal ganglion cell axons (4). The slowest group of proteins, designated slow component a (SCa), has a transport rate of 0.25 mm/d and consists of tubulin and neurofilament protein. The other slowly transported group of proteins, designated slow components b (SCb), has a transport rate of 2-3 mm/d and consists of many polypeptides, one of which is actin (4). Our analyses of the transport kinetics of the individual polypeptides of SCa and SCb indicate that (a) the polypeptides of SCa are transported coherently in the optic axons, (b) the polypeptides of SCb are also transported coherently but completely separately from the SCa polypeptides, and (c) the polypeptides of SCa differ completely from those comprising SCb. We relate these results to our general hypothesis that slow axonal transport represents the movements of structural complexes of proteins. Furthermore, it is proposed that SCa corresponds to the microtubule- neurofilament network, and that SCb represents the transport of the microfilament network together with the proteins complexed with microfilaments.
An efficient implementation of a new DOP model

Two apparently opposing DOP models exist in the literature: one which computes the parse tree involving the most frequent subtrees from a treebank and one which computes the parse tree involving the fewest subtrees from a treebank. This paper proposes an integration of the two models which outperforms each of them separately. Together with a PCFG-reduction of DOP we obtain improved accuracy and efficiency on the Wall Street Journal treebank. Our results show an 11% relative reduction in error rate over previous models, and an average processing time of 3.6 seconds per WSJ sentence.
Conditional-Sorting Local Binary Pattern Based on Gait Energy Image for Human Identification

Gait recognition systems have recently attracted much interest from biometric researchers. This work proposes a new feature extraction method for gait representation and recognition. The new method is extended from the technique of Local Binary Pattern (LBP) by changing the sorting method of LBP according to the blend direction to create a new approach, ConditionalSorting Local Binary Pattern (CS-LBP). After synchronizing and calibrating the gait sequence images, a cycle of images from the gait sequence can be captured to form a Gait Energy Image (GEI). We then apply the CS-LBP on GEI to derive different blend direction images and calculate the recognition ability for each blend direction image for feature selections. To solve the classification problem, the Euclidean distance and Nearest Neighbor (NN) approaches are used. With the experiments carried out on the CASIA-B gait database, our proposed gait representation has a very good recognition rate.

Development and validation of a university students’ progression in learning quantum mechanics through exploratory factor analysis and Rasch analysis

ABSTRACT We report an empirical study on the development and validation of a learning progression (LP) in quantum mechanics (QM) at university level. Drawing on research results about students’ reasoning in QM, we designed a hypothetical LP (HLP) consisting of three Big Ideas: Measurement, A toms and Electrons, Wave function. We then developed ten Ordered-Multiple-Choice (OMC) items to assess the construct validity and hierarchy of HLP levels. We administered the questionnaire to 244 students attending the Bachelor in Physics, divided into three groups under different instruction conditions: no course, introductory course, introductory and upper-level course. An additional group of 43 non-physics students, who attended an introductory QM course, was also involved to inspect the role of physics background knowledge . We used exploratory factor analysis and Rasch analysis to analyse collected data. The results provided evidence for the revision of the HLP around only two Big Ideas – Atomic description and measurement; Wave function and its properties in the measurement process – which roughly match the topics covered in the introductory and upper-level courses, respectively. However, the hierarchy of hypothesised levels was substantially confirmed. Implications of our findings for the teaching of QM, and the improvement of the revised LP are also discussed.
ON THE CAUSE OF THE LOCALIZATION OF SECONDARY TUMORS AT POINTS OF INJURY

The cause of the frequent localization of secondary tumors at points of injury is not known. Our work deals with this problem. For the experiments the peritoneal cavity has been employed as offering relatively uncomplicated conditions, and the fate of mouse tumor brought into contact with a peritoneal lining injured in various ways has been studied. The injection of a suspension of mouse tumor into a healthy peritoneal cavity has little success as a rule compared with a similar injection into the subcutaneous tissue. We have found that the resistance of the peritoneal lining thus indicated can be largely if not completely abolished by the preliminary injection of a mechanical irritant (Kieselguhr, lycopodium). That the change thus brought about is independent of general immunity phenomena is shown by the fact that a local injury renders susceptible the part of the peritoneum immediately affected and that part only. Special tests show that the factor important in rendering the peritoneum more susceptible is the injury to the subendothelial connective tissue. Susceptibility persists after the endothelium has regenerated over the reacting connective tissue. Schmidt has found that the cells of tumor emboli in the pulmonary arterioles are able to penetrate the endothelium of the vessel only after they have been provided with a stroma from the subendothelial connective tissue. Our findings are easily explained on the basis thus suggested. A connective tissue highly cellular and perhaps still proliferating as the result of injury may well elaborate the stroma for a tumor more rapidly than normal connective tissue. Tests of growth in vitro support this idea. Connective tissue reacting to an injury grows profusely and almost immediately when incubated in plasma, whereas normal tissue from the same region shows usually no growth whatever. Dead tumor fragments in contact with the peritoneum cause a change favorable to the lodgment and growth of later tumor fragments. It seems not improbable that the peritoneal dissemination of certain human neoplasms may be accomplished indirectly through the death of the first tumor fragments cast off. Our observations have been purposely confined to the effects of injury on the peritoneal lining ; but they seem to afford the basis for a generalization. The secondary localization of tumors at points of injury may be attributed with good reason to the presence at such points of an active connective tissue capable of elaborating a stroma rapidly and abundantly. For it is the proliferation of the subendothelial connective tissue to form a supporting stroma that determines the fate of free tumor cells, whether these lie on the peritoneum or within a vessel.
