Blind Image Quality Estimation Using Deep Neural Networks Explicit Image Position

Blind image quality assessment (BIQA) is very challenging problem due to the unavailability of a reference image. State of-the-art BIQA methods usually learn to find the image quality by regression from human subjective scores of the training samples. These methods uses to large number of human scored images for training, and lack an explicit explanation of the image quality is affected by image local features. We propose a family of image quality assessment (IQA) models based on natural scene statistics (NSS) is predict the subjective quality of a distorted image without reference to corresponding distortion less image and without any training results on human opinion scores of distorted images. Different from most deep neural networks (DNN), We take biologically inspired generalized divisive normalization (GDN) instead of rectified linear unit (ReLU) as the activation function. We empirically demonstrate that GDN is effective at reducing model parameters while achieving similar quality prediction results. The proposed model is extensively find the large scale benchmark databases to deliver high performance with state-of-the-art BIQA models as well as with some well-known full reference image quality assessment models. The proposed algorithm uses natural scene statistics in spatial domain for generating wake by distribution statistical model to extract quality aware features. The features are fed to an SVM regression model to predict quality score of input image without any information about the distortions type or reference image.
Regular Behavior of the Maximal Hypergraph Chromatic Number

Let $m(n,r)$ denote the minimal number of edges in an $n$-uniform hypergraph which is not $r$-colorable. It is known that for a fixed $n$ one has \[ c_n r^n < m(n,r) < C_n r^n. \] We prove that the sequence $a_r := m(n,r)/r^n$ has a limit, which was conjectured by Alon.
Recovery of oils from press cakes by CO2-based technology

In a context of a strong demand for vegetable oils, the development of new “green” processes is essential to provide methods that avoid the use of organic solvents, work at relatively low temperatures and preserve the quality of the final products. The supercritical fluid extraction (SFE) process meets these objectives. In this study, five meals (hemp, flax, sesame, poppy and walnut) were subjected to SFE at 45 °C and 250 bar in the presence of ethanol as co-solvent. Using this method, between 77 and 98% of the lipids present in the meal could be extracted. Except for poppy, 50% of the lipids present in the cake were recovered as a separate oily liquid phase. SFE was not selective toward certain types of triglycerides: the oils obtained exhibited the same fatty acid profile than the total lipid extracts from the cakes. In contrast, the composition in minor lipid components was dependent on the type of meal investigated. For example, hemp lipid extract was particularly rich in chlorophyll.
Digestible isoleucine requirements for 22- and 42-day-old broilers

Current experiment established different criteria to evaluate the requirements of digestible isoleucine for 22- and 42-day-old broilers by different regression models (quadratic, exponential and Linear Response Plateau) and, in the case of statistical significance, the comparison of means by Duncan's test at 5% probability. A total of 1,920 Cobb 500 male broilers were used in an entirely randomized experimental design, with 6 treatments (6 digestible isoleucine levels: 0.6118; 0.6655; 0.7192; 0.7729; 0.8265 and 0.8802%) and 8 replications, with 40 broilers each. Data on performance and carcass characteristics were evaluated. Level 0.7192% of digestible isoleucine was considered standard. The digestible isoleucine level recommended for 22- and 42-day-old broilers is 0.7729%, corresponding to a digestible isoleucine:lysine ratio of 72%.
Weeds and Food Diversity: Natural Yield Assessment and Future Alternatives for Traditionally Consumed Wild Vegetables

Abstract Wild edible plants, and particularly weeds, continue to be an important dietary component of many people around the world. We study the availability and yield of 15 weedy vegetables traditionally consumed in the Mediterranean region to assess their potential sustainable exploitation. Fieldwork was conducted in Central Spain during 2007–2009. Yields ranged between 10–460 g per plant in non-clonal species and between 400–5,000 g m−2 in clonal species. According to local plant density estimates, a total of 1800 kg ha−1 for Foeniculum vulgare, 700–1000 kg ha−1 for Beta maritima, Rumex pulcher, Papaver rhoeas and Silybum marianum, and 80–400 kg ha−1 for the remaining species could be obtained, except for Scolymus hispanicus that only yielded 30 kg ha−1. Exploitation of those species should consider local yields and preferences to achieve sustainability. We propose: 1) organic cultivation for highly valued species with low production rates in the wild (e.g., Scolymus hispanicus and Silene vulgaris); 2) commercial wild collection for culturally appreciated species with high yields in the wild (e.g., Allium ampeloprasum and Chondrilla juncea); and 3) maintenance of traditional practices and rates of harvest for all species for self-consumption.
Effect of Pregnancy on Milk Yield and Composition in Dairy Buffaloes

Changes in milk yield and composition with pregnancy were investigated, using forty lactating buffaloes. They were grouped as high, moderate and low yielder on the basis of daily milk yield. The animals were synchronized for estrus and inseminated artificially. Milk yield was recorded daily and sampled fortnightly for analysis up to 23 week post conception. The data collected were analyzed through SPSS 11 software. Results showed a significant effect (P<0.05) of production groups, pregnancy, weeks post conception, ration and their interaction on post conception milk yield. Among the three production groups milk yield decline was maximum in high yielder (49.41 liters) followed by moderate (38.26 liters) and low yielder (28.08 liters), respectively. In pregnant animals the mean milk yield was lower (37.143 liters) then the non pregnant buffaloes (40.46 liters). Decline in milk yield became significant after week 8 post conception. Present study reported significant effect (P<0.05) of production groups, pregnancy, weeks post conception, ration and their interaction on post conception milk fats contents. Effect on other milk constituents was non significant. However, Pregnancy and weeks post conception had a significant (P<0.05) effect on SNF (%), milk protein (%) and lactose (%). The mean milk fats (%) for non pregnant buffaloes was higher (7.84 %) as compared to pregnant buffaloes (7.09 %). Feed supplementation of pregnant animals significantly (P<0.05) increased milk fats (7.87 vs 7.09) and lactose (5.26 vs 5.22) contents while the rest of contents did not respond. Milk fats contents increased significantly (P<0.05) and linearly with pregnancy weeks in all the three production groups. It was concluded that milk yield started decreasing with advancement in pregnancy and got pronounced (P<0.05) on week 8 Milk fat contents in buffaloes decreased with advancement in weeks post conception as compared to their non pregnant counter part.
Controlling Sources of Inaccuracy in Stochastic Kriging

ABSTRACT Scientists and engineers commonly use simulation models to study real systems for which actual experimentation is costly, difficult, or impossible. Many simulations are stochastic in the sense that repeated runs with the same input configuration will result in different outputs. For expensive or time-consuming simulations, stochastic kriging is commonly used to generate predictions for simulation model outputs subject to uncertainty due to both function approximation and stochastic variation. Here, we develop and justify a few guidelines for experimental design, which ensure accuracy of stochastic kriging emulators. We decompose error in stochastic kriging predictions into nominal, numeric, parameter estimation, and parameter estimation numeric components and provide means to control each in terms of properties of the underlying experimental design. The design properties implied for each source of error are weakly conflicting and broad principles are proposed. In brief, space-filling properties, “small fill distance” and “large separation distance,” should be balanced with replication at distinct input configurations, with number of replications depending on the relative magnitudes of stochastic and process variability. Nonstationarity implies higher input density in more active regions, while regression functions imply a balance with traditional design properties. A few examples are presented to illustrate the results. Supplementary materials providing proofs of the theoretical results and code for comparisons are available online.

Present study attempts to evaluate the qualitative analysis, antibacterial and antioxidant efficacy of the petroleum ether, dichloromethane, ethyl acetate, ethanol and aqueous extracts of Eolvulus alsinoides L. Antibacterial activity of the crude extracts of E. alsinoides was tested against gram-positive Staphylococcus aureus and gram-negative Salmonella typhi, Acinetobacter baumannii, Klebsiella pneumoniae, Escherichia coli and Pseudomonas aeruginosa using agar well diffusion method. Aqueous extract showed maximum inhibitory activity against A. baumannii (13 and 16 mm) followed by E. coli, S. aureus and K. pneumoniae. Phytochemical analysis indicated the presence of flavonoids, alkaloids, triterpenes, glycosides, terpenoids, anthraquinones, phytosterol, polyphenol, tannins and sterols. Radical scavenging activities of petroleum ether, chloroform, ethyl acetate, ethanol and aqueous extracts of E. alsinoides ranged from 5.11-28.87%, 8.91-. 29.85%, 14.85-45.70%, 17.98-53.38% and 35.89-75.16% respectively. Among all the extracts, aqueous showed higher activity followed by ethanol, ethyl acetate, chloroform and hexane. The findings of the study indicated a reasonable antibacterial potential and significant total antioxidant activity, thus supporting its traditional medicinal practices.

Advances in Radio Science 3-D eigenmode calculation of metallic nanostructures

In the calculation of eigenfrequencies of 3-D metallic nanostructures occurs the challenge that the material parameters depend on the desired eigenfrequency. We propose a formulation where this leads to a polynomial eigenvalue problem which can be tackled by different solving strategies. A comparison between a Newton-type method and a Jacobi-Davidson algorithm is given.

ASSESSMENT OF HEALTH RELATED LIFE QUALITY IN TYPE 2 DIABETIC PATIENTS IN ZAGAZIG UNIVERSITY HOSPITALS

Submit Date 2019-03-18 Revise Date 2019-04-22 Accept Date 2019-04-25 ABSTRACT Background: The fourth leading cause of death is type 2 Diabetes Mellitus (DM). Attention to the QOL of the patient is increasing today rather than the longevity of the patient. Therefore, to prevent aggravation of metabolic disorders, the quality of life of diabetic patients should be maintained. There is a growing awareness that patient QOL and satisfaction with treatment have been improved after good glycemic control. The aim of this study was to assess health related quality of life in patients with type 2 diabetes attending Zagazig University hospital plus associations between HRQOL scores and some variables playing role in scenario of DM were also studied. Methods: A cross sectional study included 100 type 2 diabetic patients, They were subdivided according to glycemic control into 2 groups and 50 non-diabetic participants as control. This study was conducted in Internal Medicine department and diabetes outpatient clinic in Zagazig University hospital in period from July 2016 to July 2018. The QOL was measured using SF-36 questionnaire. Results: Our results revealed that there was highly significant difference regarding physical health component among groups of study (p <0.001). There was also highly significant difference regarding mental health component among groups of study (p <0.001). There was highly significant negative correlation between QOL components and age & BMI & duration of DM & HBA1c and fasting blood sugar in diabetic patients (p <0.001). Conclusions: Type 2 diabetes mellitus in both the physical health and mental health domains is associated with a lower quality of life. Advanced age, obesity and poor glycemic control were factors related to lower quality of life in this study; therefore glycemic control is highly needed to improve the quality of life of diabetic patients.
CT colonography : can it be used as a primary screening method for colorectal cancer in place of standard colonoscopy?

Introduction: Colorectal cancer (CRC) is a common and preventable cancer. Currently, several methods exist for CRC screening, including computed tomography. CT colonography is a new, minimally invasive technique for examining the entire colon using CT imaging. It is the aim of this study to present current research on CRC screening and investigate whether CT colonography could be a primary screening method for CRC. Methods: Literature searches on PubMed, the Mulford Library catalog, Ohiolink, and Google were used to research CRC, CRC screening, and CT colonography. Discussion: The sensitivity of CT colonography for advanced adenomas is comparable to or better than standard colonoscopy. Due to limited use in screening populations, the widespread cost effectiveness and acceptance of CT colonography is difficult to determine. Preliminary studies have shown good results. Conclusion: CT colonography provides a promising alternative for CRC screening in hopes that more patients will choose to undergo screening.
Chapter 2 Effects of Working Parameters on Electrospinning

Working parameters are very important to understand not only the nature of electrospinning but also the conversion of polymer solutions into nanofibers through electrospinning. Those parameters can be broadly divided into three parts such as solution parameters, process parameters, and ambient parameters. Each of those parameters can affect the fibers morphologies and by proper control of those parameters we can fabricate electrospun fibers with desired morphologies and diameters. In this chapter, we will present a concise introduction of those parameters and their influence on fiber properties.

Estimation of Natural Hazard Damages through the Fusion of Change Maps Obtained from Optical and Radar Earth Observations

The Earth’s land-cover is exposed to several types of environmental change, caused by either human activities or natural disasters. On 11 March 2011, an earthquake occurred about 130 km off the east coast of Sendai City in Japan. This earthquake was followed by a huge tsunami, which caused devastating damages over wide areas in the eastern coastline of Japan. Due to the occurrence of natural disasters across the world, there is a strong need to develop an automated algorithm for the fast and accurate extraction of changing landscapes within the affected areas. Such techniques can accelerate the process of strategic planning and primary services to move people into shelters and to carry out damage assessments as well as risk management during a crisis. Therefore, a variety of change detection (CD) techniques has been previously developed, based on various requirements and conditions. However, the selection of the most suitable method for change detection is not easy in practice. To the best of our knowledge, there is no existing CD approach that is both optimal and applicable in the cases of using a variety of optical and radar remote sensing images. To resolve these problems, an automated CD method based on a support vector data description (SVDD) classifier is proposed. This method uses the information contents of radar and optical data simultaneously by decision-level fusing of the change maps obtained from these data. For evaluating the efficiency of the proposed method and extract the damaged areas, the 2011 Sendai tsunami was considered. Various optical and radar remote sensing images from before and after the 2011 Sendai tsunami acquired by IKONOS and Radarsat-2 were used. The results confirmed the fundamental role and potential of using both optical and radar data for natural hazard damage detection applications.
Culture and the Evolutionary Process

How do biological, psychological, sociological, and cultural factors combine to change societies over the long run? Boyd and Richerson explore how genetic and cultural factors interact, under the influence of evolutionary forces, to produce the diversity we see in human cultures. Using methods developed by population biologists, they propose a theory of cultural evolution that is an original and fair-minded alternative to the sociobiology debate.
Fluidtransport entlang von Störungen und Klüften im Gebiet des Hengill-Vulkans, SW-Island

Das Holozäne Hengill-Vulkansystem liegt in der aktiven Westvulkanischen Zone in Südwestisland. Es beinhaltet den Hengill-Zentralvulkan, der sich südlich des Sees Thingvallavatn befindet, und ist eines der aktivsten geothermischen Systeme Islands (Abb. 1). Die aktuelle Spreizungsrate in der Westvulkanischen Zone liegt zwischen 3 und 7 mma−1 bei einer Subsidenzrate von 1 mma−1 (Tryggvason 1982; La Femina et al. 2005). Das Hengill-Vulkansystem ist 60–70 km lang und zwischen 5 und 10 km breit. Strukturgeologisch wird das Gebiet von großen NNE-streichenden Abschiebungen dominiert. Der Hengill-Vulkan selbst liegt in der Nähe des Tripelpunktes zwischen der Reykjanes-Halbinsel, der Westvulkanischen Zone und der Südisländischen Seismischen Zone. Diese besondere plattentektonische Konfiguration ist eine der Ursachen für die sehr hohe seismische Hintergrundaktivität. So wurden allein in dem Zeitraum zwischen 1994 und 1998 mehr als 80.000 Erdbeben kleiner Magnitude im Gebiet um den Hengill registriert (Vogfjord et al. 2005). Ungefähr die Hälfte davon zeigte Herdflächenlösungen, die auf Abschiebungen und auf Seitenverschiebungen zurückzuführen sind. Die Seitenverschiebungen bilden in diesem Gebiet ein konjugiertes System von NNE-streichenden dex-
Differential response of microbial respiration to supplied nitrogen forms in 3 contrasting alpine meadow soils on the Tibetan Plateau

ABSTRACT: An incubation experiment was conducted to examine the effects of nitrogen (N) applications in different forms (NH 4 NO 3 , NH 4 Cl, and KNO 3 ) on microbial respiration considering 3 different alpine meadow soils (C poor soil, pH = 8.1, 1.6% C; C moderate soil, pH = 6.0, 5.0% C; C rich soil, pH = 7.1, 7.4% C) in the Tibetan Plateau. The addition of NH 4 NO 3 and NH 4 Cl increased the microbial respiration in C poor soil, but KNO 3 had no effect. The inorganic N forms had no effects on C rich soil, but decreased microbial SOIL AND PLANT NUTRITION - Article Differential response of microbial respiration to supplied nitrogen forms in 3 contrasting alpine meadow soils on the Tibetan Plateau Xiaoyang Zeng* Sichuan College of Architectural Technology - Department of Landscape Architecture - Chengdu (Sichuan), China. *Corresponding author: zengxy@sina.cnReceived: Apr. 26, 2016 – Accepted: Oct. 3, 2016 respiration in C moderate soil. Soil microbial respiration levels across the different types were ordered as follows: C poor soil < C rich soil < C moderate soil, regardless of N addition. These results suggest that the effect of N on microbial respiration in alpine meadow soils is more dependent on the initial soil pH than on soil C availability.
