Real forms of the radon-penrose transform

The complex Radon correspondence relates an n-dimensional projective space with the Grassmarm manifold of its p-dimensional planes. This is the geometric background of the Radon-Penrose transform, which intertwines cohomology classes of homogeneous line bundles with holomorphic solutions to the generalized massless field equations. A good framework to deal with such problems is provided by the recently developed theory of integral transforms for sheaves and £>-modules. In particular, an adjunction formula describes the range of transforms acting on general function spaces, associated with constructible sheaves. The linear group SL(n + 1,C) naturally acts on the Radon correspondence. A distinguished family of function spaces is then the one associated with locally constant sheaves along the closed orbits of the real forms of SL(n 4- 1, C). In this paper, we systematically apply the above-mentioned adjunction formula to such function spaces. We thus obtain in a unified manner several results concerning the complex, conformal, or real Radon transforms.
Withaferin A inhibits osteosarcoma cells through inactivation of Notch-1 signalling

Human osteosarcoma cells were treated with withaferin A and the anti-proliferative activity was evaluated by the 3-(4, 5 dimethyl-thiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assays. Real-time RT-PCR and western blot were used to investigate whether the down-regulation of Notch-1 contributes to withaferin A-induced inhibition of proliferation in osteosar-coma cells. The results showed that withaferin A caused marked inhibition of osteosarcoma cell growth and G2⁄M phase cell cycle arrest. This was associated with concomitant attenuation of Notch-1 and down-regulation of its downstream genes, such as matrix metalloproteinases. These results suggest that antitumor activity of withaferin A is mediated through a novel mechanism involving inactivation of the Notch-1 signalling pathway. Our data provide the first evidence that the down regulation of Notch-1 by withaferin A may be an effective approach for the treatment of osteosarcoma. DOI: http://dx.doi. org/10.3329/bjp.v9i3. 19568
What Drives the Profitability of Japanese Multi-Divisional Corporations? Decomposing the Dispersion of Returns with a Variance Components Analysis

As is the same in the United States first shown by Rumelt (1991) using a variance components analysis, we report by far the largest contribution to the dispersion of returns is brought about by business-unit (segment) effects in Japan, though industry and corporate (headquarters) effects exert some influence. Accordingly, more attention should be paid on the strategy of a business-unit itself, at least as much attention as now focused on corporate (headquarters) strategy, in order to understand what is going on in Japanese multi-divisional corporations.
Response of soil respiration to temperature and soil moisture: Effects of different vegetation types on a small scale in the eastern Loess Plateau of China

Soil respiration is affected by vegetation and environmental conditions. The purpose of this study was to investigate the effect of vegetation type on soil respiration, temperature and water content, and their correlations on a small scale. We measured soil respiration rate (Rs) over a 3-year period at biweekly intervals in three plots in the eastern Loess Plateau of China, with the same soil texture but different vegetation types: pine forest, grassland, and shrub land. Simultaneously, soil temperature (Ts) at 10 cm depth and soil water content (Ws) within 10 cm depth were measured. The seasonal course of Rs and Ts showed a similar temporal variation in the three plots, with higher values in summer and autumn and lower values in winter and spring. No significant differences (P>0.05) were found between plots, except for Ws. The mean cumulative release of CO2 efflux from March to December was 962.5, 1027.5, and 1166.5 g C m− 2 a− 1 for plots 1, 2, and 3, respectively, with no significant difference between plots. The fitted exponential equations of Rs versus Ts from the 3-year data-set were significant (P < 0.05) with an R2 of 0.72, 0.64, and 0.72 for plots 1, 2, and 3, respectively. The calculated Q10 from the parameters of the fitted equation was 3.57, 3.52, and 3.61, and the R10 was 2.36, 2.03, and 2.37 μmol CO2 m− 2 s− 1 for plots 1, 2, and 3, respectively. Compared with the Ts, the correlations between Rs and Ws were not significant for the three plots. However, if the Ts was above 10°C, then their correlation was significant, and Ws had an impact on Rs. Four combined regression equations including two variables of Ts and Ws could be well established to model correlations between Rs and both Ts and Ws. Our study demonstrated that the exponential and power model fitted best and no significant different correlations of combined equations existed between the three plots. These results show that vegetation type had little impact on Rs, Ts, Ws, and their correlations, as well as on related parameters such as Q10 and R10. Therefore, while doing Rs research in a horizontal patchy vegetation conditions on a small area, the sampling location of measurements should focus on vertical dominant vegetation and ignore patch vegetation so as to reduce field work load.
A new strategy for active learning to maximise performance in intensive courses

This paper describes an innovation in the delivery of an introductory thermodynamics course offered to students studying towards an engineering qualification. The course was delivered in intensive format, across three weeks of study. Students find it challenging to engage with complex engineering topics in a short period of time, and there is no sizeable study break for pre-exam study. This means that students cannot afford to delay in learning and applying content. Every class must be an opportunity to interact with the content immediately. The innovation described here involved implementing a new daily structure for the course that attempted to mimic the standard process by which students learn material, apply it, study it and practice it in across a traditional-length semester. The new structure involved integrating the lecture and recitation components to the course to increasing the active learning during material delivery, then allowing students to engage in guided study and open-book formative assessment. This paper describes the implementation of this innovation. A brief review of the literature on intensive courses is provided, followed by a description of the approach used in this particular class. The results are then presented, and evaluated in the context of the research and the instructor’s own critical reflection.
A note on $L(p,\,q)$ spaces and Orlicz spaces with mixed norms

Therefore, if k E [X, Y] then Zk(f) = f k(x, y)f(y) dy defines a bounded linear operator Zk: X -e Y. In the qualitative theory of integral equations (cf. [2]) it is important to determine necessary and sufficient conditions for a continuous embedding Z C [X, Y] to hold. It is well known, and easy to see, that Z is continuously embedded in [X, Y] if and only if X 0 IT Y' is continuously embedded in Z' (cf. [8]). In [10] the following results are obtained for tensor products of L(p, q) spaces and Orlicz spaces (the symbol c will be used to denote a continuous embedding).
AU Classification using AAMs and CRFs

Automatic facial expression recognition is an important problem in social signal processing that has applications ranging from treatment of autistic children to monitoring of conflict situations [6]. In psychology, facial expressions are generally described using the Facial Action Coding System (FACS; [2]), in which each facial muscle is referred to as an action unit (AU) that is present (i.e. muscle contracted) or not present (i.e. muscle relaxed). We developed a system that automatically classifies AUs based on (variations in) facial texture and shape features. The feature extraction is performed with the help of an active appearance model [1]. Detection of AU presence is performed by training a newly developed structured prediction algorithm [5] on the features thus obtained. A complete description of our system was published in [4].
Evolutionary History of the Extinct Otter Lived in Japanese Islands

Although the river otter (Lutrinae) of Japan was distributed in four main Japanese islands until the 1920s, this animal has not been observed in the wild since 1979. Additionally, the taxonomic status of this otter remains controversial. Previous morphological and molecular genetics studies have suggested that the Japanese otter from the Honshu and Shikoku islands is an independent species of the genus Lutra, namely, Lutra nippon. However, there are pros and cons about this classification. In a recent study, our group determined the mitochondrial genome sequence of the two Japanese otter museum specimens, using next-generation sequencing technology, and evaluated the phylogenetic status of these specimens in the clade of Lutrinae. We suggested that the Japanese otter is of the genus Lutra and that two genetically divergent lineages exist among the Japanese otters living on Honshu and Shikoku. One of the lineages, which diverged from the ancestor of L. lutra at 1.27 million years ago, it should be treated either as the independent species L. nippon or as an independent subspecies of the Eurasian otter Lutra lutra nippon. The other lineage, which diverged from the ancestor of the Chinese population of L. lutra at 0.10 million years ago, was identified as L. lutra. However, in our previous study, we had analyzed genetic material from only one individual in each lineage. Therefore, our results cannot conclusively illustrate the natural history of the Japanese otter. Hence, future studies should use more than one individual to evaluate the genetic divergence of population of the Japanese otter.
Measurements of Shielding Effectiveness of Textile Materials Containing Metal by the Free-Space Transmission Technique with Data Processing in the Time Domain

The results of shielding effectiveness (SE) measurement s of textile materials containing metal by the free-space transmission technique (FSTT) in the 1-26.5 GHz frequency range are presented in the paper. It is shown that experimental data processing using time -domain gating (TDG) makes it possible to effective ly remove diffracted and reflected components from the desired signal. The comparison with the results obtained by other techniques, namely modified FSTT with TDG and coaxial line probe technique (ASTM D4935 -99) is given. The comparison shows that the prop osed technique gives more reasonable results while the measurement set-up is simpler in realization.

Evaluation of Hotel Loyalty Program with Game Refinement Theory and Analytic Hierarchy Process

This paper explores a novel way to evaluate the benefit of gamified strategy in business domain with a focus on hotel loyalty program that is a key strategy in attracting business to its properties. It presents a data-driven approach for discovering the patterns of different hotel loyalty programs using analytic hierarchy process, whereas a measure of game refinement is employed to quantify the game sophistication level of each gamified strategy. The results show interesting observations on the game sophistication of hotel reward in a specific area. Meanwhile, it is found that the selected comparison items of these hotel rewards and the number of the customers are highly related.
Exophytic Tumours of Skin of the Head – Case Study and Review of the Literature

Basal Cell Carcinoma (BCC) and squamous Cell Carcinoma (sCC) – the most common of nonmalanotic skin cancers are at the same time the most common cancers in general, rarely resulting in metastasis, but of great risk of local recurrence. The authors present factors which are responsible for developing nonmalanotic skin tumors, such as environmental factors (ultraviolet radiation, arsenic exposure, phototeraphy, radioteraphy) and endogenic (immunosuprecy, patient age, virus infection). They present review of proposed and used method of treatment BCC and sCC. in the following paper three cases of patients operated in their clinic are presented, which proves that there is a lack of social awareness of the necessity of treatment of such cancers and oncological vigilance among general practitioners. The authors want to stress the necessity for establishing algorithms of after surgery treatment and long term observation of patient treating for nonmalanotic skin cancers (Dent. Med. Probl. 2013, 50, 2, 229–237).
Towards Improved User-Product Testing With Cognitively Enhanced Scenarios

With the increasing information-intensiveness of products, users are challenged with expanding options and possible ways to interact. Rapidly escalating numbers of possible useroperation sequences hinder designers in anticipating all possible (unacceptable) outcomes. Interactively simulating product models with human subjects to explore all options is not practicable. Virtual simulation with computer models of users can open the way towards faster-than-real-time performance and investigation of massive numbers of interaction sequences. This paper reports on opportunities to improve realism of virtual-use simulations by incorporating knowledge about the workings of the human brain We elaborate how, in particular, cognitive-architecture simulations developed by cognitive scientists and error phenotypes identified in human reliability analysis (HRA) can extend a virtual-use simulation approach that we have proposed in foregoing work, by offering the prospective of generating interaction sequences with erroneous user actions unforeseen by the designer. We outline how such an integrated system can be implemented and also discuss validation issues.
Biogenic volatile organic compounds: The state of knowledge in southern Africa and the challenges for air quality management

Emissions of biogenic volatile organic compounds (BVOCs) on an urban and regional scale compare with those from anthropogenic sources, both in magnitude and in their role in atmospheric photochemistry and in the formation of ozone. Despite this, research on BVOC emissions in southern Africa has been limited to relatively few plant species in savannas, woodlands and shrublands. Extrapolation of these values provides an estimated annual emission of 80 Tg C for the subcontinent. Isoprene and monoterpene emissions vary widely according to plant species, temperature, foliar density and photosynthetically active radiation, and also diurnally and with season. Savanna trees such as Acacia nigrescens and Burkea africana are high isoprene emitters, and monoterpene emissions from Colophospermum mopane and Acacia tortilis are significant. By comparison, some tree species, such as Combretum molle and Sclerocarya birrea, emit neither compound. The legal prerequisite for holistic air quality management in South Africa, together with the dearth of information on BVOC emissions and an understanding of their role in the formation of ozone, poses significant challenges for policy-makers, air quality managers and scientists in southern Africa.

Application of marker-assisted selection for ahFAD2A and ahFAD2B genes governing the high-oleic acid trait in South African groundnut cultivars ( Arachis hypogaea L.)

One of the major shortcomings in cultivated groundnut in South Africa is the short shelf-life of the product due to rancidity of the oil rich seeds. Polyunsaturated fatty acids are more susceptible to oxidation than mono-unsaturated residues. Thus, it would be preferable to adjust the oleic acid: linoleic acid ratio to a more favourable one. The high-oleic acid trait in groundnut was reported to be dependent on two homeologous oleoyl-PC desaturase genes, ahFAD2A and ahFAD2B. Breeding of new cultivars with this characteristic can be time-consuming and expensive when doing fatty acid analysis in every generation for selection of the progeny with the highest oleic acid: linoleic acid ratio. Marker-assisted selection was applied to the local groundnut breeding program with the utilization of real-time polymerase chain reaction (PCR). The inheritance of the high oleic trait was followed in the 4th backcross progeny and revealed that all combinations of the two genes were found, except the ol 2 ol 2 homologous mutant. The highest oleic acid percentage was found in progeny with all four mutant alleles ( ol 1 ol 1 ol 2 ol 2 ). Keywords : High-oleic, real-time PCR, oleoyl PC desaturase, marker-assisted selection African Journal of Biotechnology Vol. 12(27), pp. 4283-4289
History and Nation Imagination: Igbo and the Videos of Nationalism

The inviolability of the nation/state has in recent times been violently contested by some of the different national identities that forge the nation entity. Instancing one such contestation in the Nigeria/Biafra civil war, this paper examines the manner in which two Igbo video films function as ethno-nationalist texts by presenting ideologically skewed historical counter-narratives that present and defend the popular Igbo position as a continuously marginalized nationality within the imagined Nigerian community.
Online multistep-ahead inundation depth forecasts by recurrent NARX networks

Various types of artificial neural networks (ANNs) have been successfully applied in hydrological fields, but relatively scant on multistep-ahead flood inundation fore- casting, which is very difficult to achieve, especially when dealing with forecasts without regular observed data. This study proposes a recurrent configuration of nonlinear autore- gressive with exogenous inputs (NARX) network, called R- NARX, to forecast multistep-ahead inundation depths in an inundation area. The proposed R-NARX is constructed based on the recurrent neural network (RNN), which is commonly used for modeling nonlinear dynamical systems. The mod- els were trained and tested based on a large number of in- undation data generated by a well validated two-dimensional simulation model at thirteen inundation-prone sites in Yilan County, Taiwan. We demonstrate that the R-NARX model can effectively inhibit error growth and accumulation when being applied to online multistep-ahead inundation forecasts over a long lasting forecast period. For comparison, a feed- forward time-delay and an online feedback configuration of NARX networks (T-NARX and O-NARX) were performed. The results show that (1) T-NARX networks cannot make online forecasts due to unavailable inputs in the constructed networks even though they provide the best performances for reference only; and (2) R-NARX networks consistently out- perform O-NARX networks and can be adequately applied to online multistep-ahead forecasts of inundation depths in the study area during typhoon events.
Determinants of the Food Security Status of Households Receiving Government Grants in Kwakwatsi, South Africa

This study attempts to estimate the food security status and identify the determinants of food security among households receiving government grants in a township of Kwakwatsi, South Africa. The results are based on a household survey using questionnaires. A Logistic regression model was estimated based on this data with the household food security status (that is food secure and insecure) as the dependent variable and a set of demographic variables as explanatory variables. It was found that about 38 per cent of the sampled households are food secure. The results of the regression analysis showed total householdincome, household size, employment and marital status of the household head, employment status of the spouse as important determinants of food security in the area. Household size and the marital status of the head of household were negatively associated with household food security. The age, gender and educational attainment of the household head were not significant predictors of household food security status. This study makes a contribution to the understanding of the dynamics of households dependent on government grants by modelling the factors which determine food security and may act as reference source for policy planning purposes.
Production of Functionally Graded AlB2/Al-4%Mg Composite by Centrifugal Casting

In this study, production of functionally graded AlB 2 reinforced Al-4%Mg composite has been investigated. In-situ high-aspect-ratio flake AlB 2 reinforcement was obtained by the addition of boron oxide to the liquid Al-Mg at 1400 °C. It has been observed that there were two distinct regions without a smooth grading: one is rich of and the other is poor of AlB 2 . The results showed that the highest AlB 2 content has been found to be around 10% in external zones, whereas the lowest AlB 2 content has been observed to be 0.02% in the internal zones. Additionally, results showed that, depending on the increase in the reinforcement phase in external zones, up to 20 % increase in the hardness of the composite has been achieved.
A simple automated system for hall effect measurements

This project deals with the development of a computer interfacing technique for the study of Hall effect. A stepper motor with resolution of 0.1 mm was used to move a pair of permanent magnet backward and forward against the sample. The General Purpose Interface Bus (GPIB) card together with a digital nanovoltmeter and teslameter using serial port siri RS232, interface were used to measure the potential difference and magnetic field strength, respectively. Hall effect for YBa2Cu3-xTixO7-δ system (x=0.00, 0.01, 0.03 and 0.05) showed positive sign Hall coefficient showing that the material is a hole type carrier at room temperature. Parameters such as Hall coefficient and charge carrier concentration were also display on the front panel of Lab View programming.
Cognitive Deficits Feature of Male with Attention Deficit Hyperactivity Disorder-Based on the Study of WISC-IV

Objective: This study aims to explore the characteristics of children with attention deficit hyperactivity disorder (ADHD) in the Fourth Edition of Wechsler Intelligence (WISC-IV). Methods: The boys with ADHD were tested by WISC-IV, and the comparisons with healthy children were performed. Results: The total IQ, (t=-4.964, P<0.001), general ability index (t=-2.443, P=0.016) and cognitive efficiency index (t=-5.810, P<0.001) of the study group were significantly lower than that of the control group, of which, the working memory (t=-5.354, P<0.001), processing speed (t=-4.593, P<0.001) and its various sub-tests scores of the subscales for cognitive processing efficiency index were significantly lower than that of the control group. The incidence of the "relatively low cognitive efficiency" feature of the study group (69.23%) was significantly higher than that of the control group (46.15%) (χ2=6.923, P=0.009). The performance of the learning factor in the study group was correlated with the total IQ and working memory of WISC. Conclusions: Children with ADHD have intellectual characteristics of relatively low cognitive efficiency.
