Diffusion tensor imaging in brain tumors: The role of fractional anisotropy values

Aim: To evaluate the role of Fractional anisotropy (FA) values obtained from diffusion tensor magnetic resonance imaging (DTI) in the differentiation and grading of brain tumors. Materials and Methods: This study examined the conventional and diffusion tensor MR imaging findings of twenty-seven patients diagnosed with brain tumors between 2008 and 2010. Patients were divided into four groups based on tumor types; meningiomas, low-grade gliomas, high-grade gliomas, and metastases. Fractional anisotropy (FA) values were then obtained from the solid components and (if present) peritumoral vasogenic edema of the tumors for each patient by using the region of interest (ROI) method. Finally, the patient groups were analyzed in terms of any statistically significant differences. Results: The FA values obtained from the solid portions and peritumoral edema of meningiomas were found to be higher than those of all other groups (p<0.015). Moreover, the FA values of high-grade gliomas were found to be higher than those of low-grade gliomas (p=0.042). Finally, no statistically significant difference was observed between high-grade gliomas and metastases in terms of the FA values of solid components and peritumoral edema. Conclusion: The determination of FA values among DTI results can be a useful method for differentiating brain tumors such as meningioma, low-grade glioma, high-grade glioma, and metastasis, as the treatment protocols and prognoses of each may differ. Moreover, FA values may contribute preoperatively to the differentiation of brain tumors in multimodal brain tumor imaging. It would be useful to use diffusion tensor imaging in conjunction with conventional MRI in the imaging of brain tumors.
Manufacturer and Retailer Brand Acceptance under Different Levels of Purchase Involvement

Why compare retailer vs. manufacturer brands. The concept of retailer brands, i.e., the products marketed by retailers and often having adopted the name of the store, continues to increase in popularity in Lithuania together with the booming retail sector. In many advanced markets in Europe, the markets witnessed a long evolution from retail brands as lower quality product alternative for a lower price, to retail brands offering a true quality brand alternative and having a clear marketing approach in their retail environment (Burt, 2000; Wulf, OdekerkenSchroeder et al., 2005). According to Velotsou et al. (2004), now consumers increasingly choose between the
Effects of essential oils of Cashew and Castor on intake, digestibility, ruminal fermentation and purine derivatives in beef cattle fed high grain diets

The objective of this study was to determine the effects of essential oils of Anacardium occidentale (Cashew) and Ricinus communis (Castor) on intake, digestibility, ruminal fermentation and excretion of purine derivatives in beef cattle fed high grain diets. Five Nellore steers fitted with ruminal cannula were used in a 5x5 Latin square design (21 days period). The treatments were control MON (0.2 g monensin animal day-1¬) and 1, 2, 4 and 8 g EO animal day-1 (Essential oils - Oligobasics®). All the animals had a basal diet, corn silage-based total mixed ration (TMR) of 80:20 concentrate:forage ratio. Intake, digestibility, ruminal fermentation and excretion of purine derivatives were determined over five consecutive days in each period. Intake and digestibility of dry matter (DM), neutral detergent fibre (NDF) and crude protein (CP) were not influenced by treatments (P > 0.05). However, increasing levels of EO showed a quadratic effect (P < 0.014) above 2 g animal day-1 on the ruminal pH. The excretion of allantoin and uric acid were not influenced by the treatments (P > 0.05), but levels above 2 g day decreased the synthesis of microbial proteins (P < 0.05). It is concluded that the EO of A. occidentale and R. comunnis effectively controlled ruminal fermentation as well as sodium monensin at the studied levels. EOs have the potential to be used in place of monensin in the studied levels.
he virtual source method : Theory and case study

We present a way to image through complex overburden. The method uses surface shots with downhole receivers placed below the most complex part of the troublesome overburden. No knowledge of the velocity model between shots and receivers is required. The method uses time-reversal logic to create a new downward-continued data set with virtual sources VS’s at the geophone locations. Time reversal focuses energy that passes through the overburden into useful primary energy for the VS. In contrast to physical acoustics, our time reversal is done on a computer, utilizing conventional acquisition with surface shots and downhole geophones. With this approach, we can image below extremely complex realistic overburden — in fact, the more complex the better. We recast the data to those with sources where we actually know and can control the waveform that has a downward-radiation pattern that may also be controlled, and is reproducible for 4D even if the near-surface changes or the shooting geometry is altered slightly. To illustrate the method, we apply the VS technique to a synthetic, elastic example with extreme heterogeneity, where conventional approaches fail to image the data. A 4D fielddata example shows that the VS method VSM enables sensitive reservoir monitoring below a complex, time-variant near surface that is not achievable with surface 4D seismic or conventional 4D vertical seismic profiling VSP .
B 97 , 115401 ( 2018 ) Superconductivity induced by interfacial coupling to magnons

We consider a thin normal metal sandwiched between two ferromagnetic insulators. At the interfaces, the exchange coupling causes electrons within the metal to interact with magnons in the insulators. This electronmagnon interaction induces electron-electron interactions, which in turn can result in p-wave superconductivity. We solve the gap equation numerically and estimate the critical temperature. In yttrium iron garnet (YIG)-Au-YIG trilayers, superconductivity sets in at temperatures somewhere in the interval between 1 and 10 K. EuO-Au-EuO trilayers require a lower temperature, in the range from 0.01 to 1 K.
Impact of Innate and Cell mediated Immune Responses on Dengue Virus Dynamics

Dengue infection is one of the most prevalent mosquito-bore illnesses in the world. In order to understand how the infection can be prevented or controlled, we should first understand the dynamics of the dengue virus. The model presented here incorporates innate immune response and Cytotoxic T lymphocytes (CTL) mediated immune response which plays a crucial role in clearing the infection. The basic reproduction number R0 was computed and a detailed stability analysis was done. It was found that the model has three equilibria, namely, pathogen free equilibrium, no immune equilibrium and the endemic equilibrium. Stability at each equilibrium point is discussed with respect to R0. The proposed model also shows that introduction of immune response strongly affects the stability of the system.

University of Dundee Evaluating hospital websites in Kuwait to improve consumer engagement and access to health information

Background: Current advances in information and communication technology have made accessing and obtaining health-related information easier than ever before. Today, many hospital websites use a patient-centric approach to promote engagement and encourage learning for better health-related decision making. However, little is known about the current state of hospital websites in the State of Kuwait. This study aims to evaluate hospital websites in Kuwait and offer recommendations to improve patient engagement and access to health information. Methods: This study employs a cross-sectional analytical approach to evaluate hospital websites in Kuwait in 2017. The websites of hospitals that provide in-patient services were identified through a structured search. Only active websites that were available in either English or Arabic were considered. The evaluation of the websites involved a combination of automated and expertbased evaluation methods and was performed across four dimensions: Accessibility, Usability, Presence, and Content. Results: Nine hospitals met the inclusion criteria. Most of the websites fell short in all four dimensions. None of the websites passed the accessibility guidelines. The usability of websites varied between hospitals. Overall, the majority of hospitals in Kuwait have rudimentary online presence and their websites require careful reassessment with respect to design, content, and user experience. The websites focus primarily on promoting services provided by the hospital rather than engaging and communicating with patients or providing evidence-based information. Conclusions: Healthcare organization and website developers should follow best-practices to improve their websites taking into consideration the quality, readability, objectivity, coverage and currency of the information as well as the design of their websites. Hospitals should leverage social media to gain outreach and better engagement with consumers. The websites should be offered in additional languages commonly spoken by people living in Kuwait. Efforts should be made to ensure that health information on hospital websites are evidence-based and checked by healthcare professionals.
Deriving color adjectival nominalizations Artemis Alexiadou artemis

In this paper I examine two types of nominalizations related to color adjectives in Greek, a suffixed one and a neutral one, which I will compare to their English and Dutch (and German) counterparts. I show that the two differ in that suffixed nominalizations denote stage level properties, while neuter nominalizations denote individual level properties. This difference is due to the fact that suffixed nominalizations are count nouns, while neuter nominalizations are mass nouns. A comparison between Greek, and Dutch/German and English shows that languages have different nominalization strategies: nominalization can take place at three layers: at the root level, at the nP level, and finally at the DP level. This explains the differences in distribution and interpretation among the different nominalization types across languages.

Mortality‐risk‐based apnea–hypopnea index thresholds for diagnostics of obstructive sleep apnea

The severity of obstructive sleep apnea is clinically assessed mainly using the apnea–hypopnea index. Based on the apnea–hypopnea index, patients are classified into four severity groups: non‐obstructive sleep apnea (apnea–hypopnea index < 5); mild (5 ≤ apnea–hypopnea index < 15); moderate (15 ≤ apnea–hypopnea index < 30); and severe obstructive sleep apnea (apnea–hypopnea index ≥ 30). However, these thresholds lack solid clinical and scientific evidence. We hypothesize that the current apnea–hypopnea index thresholds are not optimal despite their global use, and aim to assess this clinical shortcoming by optimizing the thresholds with respect to the risk of all‐cause mortality. We analysed ambulatory polygraphic recordings of 1,783 patients with suspected obstructive sleep apnea (mean follow‐up 18.3 years). We simulated 79,079 different threshold combinations in 100 randomized subgroups of the population and studied the relative risk of all‐cause mortality corresponding to each combination and randomization. The optimal thresholds were chosen according to three criteria: (a) the hazard ratios increase linearly between severity groups towards more severe obstructive sleep apnea; (b) each group includes at least 15% of the study population; (c) group sizes decrease with increasing obstructive sleep apnea severity. The risk of all‐cause mortality varied greatly across simulations; the threshold defining non‐obstructive sleep apnea group having the largest effect on the hazard ratios. The apnea–hypopnea index threshold combination of 3‐9‐24 was optimal in most of the subgroups. In conclusion, the assessment of obstructive sleep apnea severity based on the current apnea–hypopnea index thresholds is not optimal. Our novel approach provides methods for optimizing apnea–hypopnea index‐based severity classification, and the revised thresholds better differentiate patients into severity groups, ensuring that an increase in the severity corresponds to an increase in the risk of all‐cause mortality.
1 THE CRAFT OF OPENNESS : ABSORPTIVE CAPACITY AT THE INDIVIDUAL LEVEL AND INNOVATION

The ability of an individual to capture knowledge from outside the firm is a critical element in the development of an organization? s absorptive capacity. Despite the acknowledgement that individuals are central to absorptive capacity, researchers have tended to overlook the roles that individuals play in exploring, assimilating and exploiting external knowledge. By defining and measuring absorptive capacity at the individual level, we seek to enrich our understanding of how individuals learn from external knowledge and how such efforts shape the ability of an individual to contribute to their organization? s innovative efforts. We posit that knowledge assimilation plays a vital role in gaining from exploring and exploiting external knowledge. That is, we argue that individuals? performance to develop innovations not only benefits from making efforts on a single dimension of absorptive capacity, but rather thrives when individuals combine efforts to explore, assimilate and exploit external knowledge. Using rich data from a large group of R&D scientists and their engagement with external sources of knowledge, we find support for our hypotheses.

OF PERFORMANCE ON NATURAL RESISTANCE IN PHEASANTS , INFECTED WITH PATHOGENIC STRAIN OF E . COLI AND TREATED WITH ENTEROCOCCUS FAECIUM

GENOVA, K. and T. MEHMEDOV, 2016. Study of performance on natural resistance in pheasants, infected with pathogenic strain of E.coli and treated with Enterococcus Faecium M74. Bulg. J. Agric. Sci., 22: 140–143 Probiotics are live micro-organisms that bring benefits to consumer health. It is well known that they are used for prevention of bacterial diseases in poultry, as well as to potent the growth performance and immune response of poultry. The present work was carried out to evaluate the effectiveness of probiotic Laktiferm Basic 300® on natural resistance in pheasants, infected with pathogenic strain of E.coli. Pheasants were inoculated intra ingluvial with enteropathogenic strain of E.coli O 103 in an amount of 108 cfu/ml on the 3rd day and divided into four equal groups: Group (1) served as a positive control group, received colistin sulfate. Group (2) was negative control. Group (3) was fed with the probiotic while group (4) was fed with nutritional antibiotic Pharmastim 8%® . Evaluations were made for immunological changes. Our results showed that Enterococcus Faecium M74 possesses positive effect on phagocytic activity and on bactericidal activity of blood serum. Significant decrease was recorded in the phagocytic percent and phagocytic index of neutrophils of pheasants in negative control.
An Overview of Reduplication in Malayic Languages Reduplication

In this paper, we study the morphosemantic aspects of reduplication in Palembang (also known as Musi). In Palembang, both content and function words undergo reduplication, generating a wide variety of semantic functions, such as pluralization, iteration, distribution, and nominalization. Productive reduplication includes full reduplication and reduplication plus affixation, while fossilized reduplication includes partial reduplication and rhyming reduplication. We employed the Distributed Morphology theory (DM) (Halle and Marantz 1993, 1994) to account for these different patterns of reduplication. Moreover, we compared the functions of Palembang reduplication to those of Malay and Indonesian reduplication. Some instances of function word reduplication in Palembang were not found in these languages, such as reduplication of question words and reduplication of negators. In addition, Palembang partial reduplication is fossilized, with only a few examples collected. In contrast, Malay partial reduplication is productive and utilized to create new words, especially words borrowed from English (Ahmad 2005).
COMPONENT MODE SYNTHESIS OF BEAM AND SHELL FINITE ELEMENTS

Abstract: A method for synthesising of beam or shell elements is proposed. It can be used to describe beams with complex cross sections and plates and shells with variable thickness and other special features. Starting point is usually a finite element model by 3D elements of desired component. Sometimes this model is combined with other types of finite elements, such classical beams, plates and shells. This allows describing of complex structures like airplane fuselages and wings, helicopter rotor blades. Using deformation and vibrating modes that are typical for beams and shells the transformation matrix is synthesized. This matrix is then used to transform stiffness matrix and mass matrix of model into matrices with much smaller size. These matrices then can be used in static or dynamic analysis as a usual beam or shell element. Simple examples are shown and results are discussed.
TWO AXIS DIRECTION FINDING ANTENNA SYSTEM USING DIFFERENCE – SUM PATTERNS IN X-BAND by SARMAD

This thesis work proposes the direction finding antenna system in two axis (θ,∅) in x-band (8 to 12 GHz) using difference (∆) and sum (∑) patterns of received signal. Direction finding system is constructed using microstrip patch antennas array and 180 hybrid rat race ring coupler which generates ∆ and ∑ of two received RF signals. Individually, both coupler circuit and antenna elements are optimized in terms of feed location and size using ADS electromagnetic simulation software. In this work, 10 GHz frequency of operation is chosen. Initially, direction of arrival (DOA) is obtained in one axis (θ) using the patterns of ∆ and ∑ ports of antenna array of two elements. Using the equations of ∆ and ∑ of two input signals, radiation patterns at different θ values have been observed in simulation and compared with measured pattern values of constructed circuit. By taking the ratio of ∆ to ∑ patterns, DOA has been estimated of designed circuit. Later, another DOA circuit in other direction (∅) is constructed and DOA has been estimated. By taking the 3D patterns of each circuit in anechoic chamber, both of these circuits are simulated and measured for performance; and from -40 to +40 degrees DOA has been observed with rms error of less than 5 degree in both axis with phi angle from 0 to 180 degrees. Another circuit which combines all these four antennas into one system also has been simulated. At 10 GHz operating frequency, experimental results using material RT Duroid 5880 (εr = 2.2, t𝑕ickness = 1.575mm) show that satisfactory performance can be achieved with proposed setup.
End-to-End QoS Guaranteed Service in WLAN and 3 GPP Interworking Network

In this paper, we model the end-to-end QoS provisioning mechanisms in the WLAN and 3GPP interworking network. For the end-to-end QoS guaranteed service, we model the control plane and user plane considering the WLAN and 3GPP interworking network. And we propose the QoS parameter/class mapping and DPS packet scheduler. By the simulation results, DPS can provide the low end-to-end delay of voice traffic, even though a traffic load increases by 96%. Especially, the end-to-end delay of voice is much smaller than without the QoS provisioning mechanisms when the QoS parameter/class mapping and DPS are applied to the interworking network.
Studies on the use of Lactobacillus rhamnosus in white soft cheese manufacture

White soft cheese is made by using different levels of Lactobacillus rhamnosus (0.0, 0.2, 0.4, 0.6 and 0.8%) (Control, T1, T2, T3 and T4) before incubation of milk. The resultant cheeses were stored at refrigerator temperature 6c up to 28 days. The data concluded that, TS, TA, SN, TN, SN/TN, TVFFA were increased and salt in water increased by increasing the L. rhamnosus level in all treatments. The control samples without culture (C) had lower TS, TA, SN, TN, SN/TN, TVFFA and salt in water ratio than that of with different levels of L. rhamnosus. The cheese made with 0.8% L. rhamnosus starter (T4) had higher values of TS, TA, SN, TN, SN/TN, TVFFA and salt in water ratio than that of other treatments. There were increased on syneresis and firmness with increasing levels of L. rhamnosus. Microbiologically, there were increases of TC, and lactobacilli counts with increasing storage periods up to the end of storage periods in all treatments. There were not detected psychotrophic bacteria and coliform group counts in all treatments. Yeast and moulds were not detected in fresh cheese and after one week of storage, but they were detected and increase gradually with the progress of storage at 14 up till 28 days in most treatments. Moreover, the data showed that T3 stored for 28 days had the highest scores than that of the other treatments using different levels of L. rhamnosus. Whilst, T3 stored for 7days had the lowest scores than that of the other treatments.
Neural , Parallel , and Scientific Computations 25 ( 2017 ) 135-148 THE METHOD OF PARTICULAR SOLUTIONS FOR FINDING CRITICAL DOMAINS FOR QUENCHING PROBLEMS THIR

ABSTRACT. In this work, the method of particular solutions (MPS) has been used for solving nonlinear Poisson-type problems defined on different geometries. The polyharmonic splines is used as the basis function so that no shape parameter is needed in the solution process. The MPS is also applied to compute the sizes of critical domains of different shapes for a quenching problem and compared with the sizes of critical domains obtained from some other numerical methods. Numerical examples are presented to show the efficiency and accuracy of the method.
