Abstract:
Summary. In connection with the growing volume of scientific data on the genetic problems of generalized epilepsy in recent decades, the ambiguity of the therapeutic tactics and prognosis of this cohort of patients has become obvious based solely on the phenotypic characteristics of the patient. It is known that epilepsies with similar phenotypes show a different genetic nature, different pathogenesis of the development of epileptogenesis and response to therapy. The outcomes also differ, both in terms of seizure control and in terms of cognitive functions.The article presents an overview of the factors that must be taken into account when manifesting childhood absentee epilepsy: the child’s gender, types of seizures, cognitive profile, results of electroencephalography and neuroimaging. Attention is paid to the genes that determine the development of these forms of epilepsy in children.

Abstract:
Purpose – The purpose of this study is to identify customer-specific differences in a general model of e-loyalty taking into account the existence of unobserved heterogeneity. Specifically, this paper aims to test for the presence of customer heterogeneity; assess the impact of potential bias when there is no control for heterogeneity; analyse the distinct customer segments that emerge from the empirical estimation of the model; and describe the segments by their demographic and psychological characteristics. Design/methodology/approach – Panel data from a survey of online shoppers are used in a post hoc segmentation method, which will enable us to identify segments, while estimating the parameters by means of structural equation models. Findings – Three distinct consumer segments emerge. The relative importance of e-loyalty and e-satisfaction is significantly determined by consumers’ shopping styles. Originality/value – This study highlights the need to consider unobserved customer heterogeneity when attempting to explain satisfaction and loyalty development processes in the retail context in general and e-commerce in particular. To the authors’ knowledge, this is the first time this approach has been used to analyse the impact of customer heterogeneity on e-satisfaction and e-loyalty.

Abstract:
Owing to the rarity and the biological and clinical heterogeneity of gastroenteropancreatic neuroendocrine neoplasia (GEP NEN), the management of these patients may be challenging for physicians. This review highlights the specific features of GEP NEN with particular attention on the role of Ki67 heterogeneity, the potential prognostic role of novel radiological techniques, and the clinical usefulness of functional imaging, including 68Ga-DOTA-SST PET/CT and 18F-FDG PET/CT. Understanding these specific features may help to plan proper and tailored follow-up programs and therapeutic approaches.

Abstract:
Measuring biodiversity of insects is an essential part in management concept of insect pest populations based on ecology. This study examined the index of insect biodiversity by measuring species richness, species evenness and heterogeneity in organic and non-organic rice farming ecosystem. The sampling was conducted during the planting season of April–May 2015 and October–November 2015 at 44, 52 and 66 days after rice transplanting (DAT). High number of species richness (7 to 13 species) was found in the non-organic rice field (April–May 2015). In contrast, high number of species richness (22 to 33 species) was found in the organic rice field (October–November 2015). The species evenness and heterogeneity in the organic farming were generally higher than these in the non-organic rice in the both of planting season April–May 2015 and October–November 2015. Overall, the organic rice farming ecosystem can increase species richness, species evenness and heterogeneity of insect. INTISARI Mengukur biodiversitas serangga adalah salah satu bagian penting dalam konsep pengelolaan populasi serangga hama berbasis ekologi. Penelitian ini mengkaji indeks biodiversitas serangga dengan mengukur kekayaan spesies (species richness), kemerataan spesies (species evenness), dan keanekaragaman/kelimpahan spesies (heterogenity) pada sistem budidaya padi organik dan non-organik. Pengambilan sampel diperoleh pada saat musim tanam April–Mei 2015 dan musim tanam Oktober–November 2015 di 44, 52, dan 66 hari setelah tanam. Total kekayaan spesies tertinggi (7–13 spesies) ditemukan di lahan padi non-organik (April–Mei 2015). Sebaliknya, total kekayaan spesies (22–33 spesies) ditemukan di lahan padi organik (Oktober–November 2015). Kemerataan spesies dan heterogenitas di lahan padi organik secara umum lebih tinggi dibanding di padi non-organik pada kedua musim tanam April–Mei 2015 dan Oktober–November 2015. Secara keseluruhan, sistem budidaya di ekosistem padi organik dapat meningkatkan kekayaan spesies, kemerataan spesies, dan heterogenitas serangga.

Abstract:
Background: Approximately 7% of clinically referred youth exhibit profound impairment in the ability to regulate their affect, behavior, and cognition. This phenotype – often referred to as dysregulation – has been associated with a multitude of negative outcomes. Symptom overlap between dysregulation and other psychological disorders has generated debate regarding whether DP constitutes a distinct syndrome characterized by intense, persistent irritability or is merely the combination of symptoms from disruptive or mood disorders. In order to elucidate this question, the current study examined the transdiagnostic continuities and discontinuities in three RDoC constructs (frustrative non-reward, acute threat, and cognitive control) proposed to be mechanisms of irritability Method: Participants were 294 children ages 7-17 (M=10.94; 67% male). Emotional and behavioral symptoms were measured using the Child Behavior Checklist and the Kiddie Schedule for Affective Disorders and Schizophrenia. Frustrative non-reward was measured using a frustration-induction Go/No-Go paradigm during which heart rate variability was indexed by respiratory sinus arrhythmia (RSA) and pre-ejection period (PEP). Acute threat was measured using an Emotional Faces computer paradigm in conjunction with an eyetracker/pupilometer. Cognitive control was assessed with the Behavioral Rating Inventory of Executive Function (BRIEF), Delis-Kaplan Executive Function System (D-KEFS) and Stop Signal Task (SST). Results: Symptoms of dysregulation and non-episodic irritability were strongly, positively related. Due to a lack of demonstrated construct validity for the hypothesized RDoC constructs of frustrative non-reward, acute threat, and cognitive control, two alternative mechanisms—SNS response and cognitive dyscontrol of emotion—were derived from the data. Results showed that blunted sympathetic responsivity and poor executive control in response to emotion were predictive of more severe irritability symptoms. Finally, moderation analyses showed that among highly dysregulated children, low levels of sympathetic responsiveness were associated with more severe irritability symptoms. Conclusions: Despite phenotypic overlap with other forms of developmental psychopathology, dysregulated children can be distinguished based on the severity of their irritability symptoms. This supports the conceptualization of dysregulation as a unique syndrome characterized by intense and persistent irritability and lends credence to the novel diagnosis of DMDD. Furthermore, cognitive, behavioral and physiological patterns identified in this study suggest that difficulties with processing negative emotion—as opposed to frustration or threat specifically—may constitute a vulnerability for irritability.

Abstract:
Advancements in Li-ion batteries are needed especially for the development of electric vehicles and stationary energy storage. Prior research has shown mesoscale variations in electrode electronic conductive properties, which can cause capacity loss and uneven electrochemical behavior of Li-ion batteries. A micro-four-line probe (μ4LP) was used to measure electronic conductivity and contact resistance over mm-length scales in that prior work. This work describes improvements to overcome the challenge of unreliable surface contact between theμ4LP and the sample. Ultimately a second generation flexible probe called the micro-radial-surface probe (μ4LP) was designed and produced. The test fixture was also optimized to obtain consistent contact with the new measurement probe and to perform measurements at a lower force. The μ4LP was then used to study the effect of heterogeneity on calendering, which is the compression of electrode films to obtain a uniform thickness and desired porosity. The thickness, electronic conductivity and contact resistance of two cathodes and one anode were measured before and after calendering. The the spatial standard deviation divided by the mean was used as a measure of heterogeneity. The results show variability in conductive properties increased for two of the three samples after calendering, despite the increased uniformity in thickness of the electrodes. This suggests that additional quality control metrics are needed besides thickness to be able to identify uneven degradation and produce longer lasting batteries.

Abstract:
The aim of this thesis is to verify the hypothesis on real data based on economic theory and these theories to confirm or reject. The first part deals with testing of hypotheses based on the game theory and tests whether tennis players play according to the minimax theory. The Hypotheses analyse the data for strong and weak players, considering their service, and verify which group of players converge in their strategies toward minimax theory assumptions. Specifically, theory components of the hypotheses are tested within this part: i) the probability of winning the game serving from the right side of a court is the same as the probability of winning the game serving from the left side, ii) this hypothesis will hold true rather in case of stronger players serving against weaker players than in case equally strong players playing against each other and iii) Based on the assumption that women do not excel distinctively in serving, the results in the women's matches will be worse in the minimax theory than results from men's matches. Hypotheses derived from the theory of elimination tournaments are tested in the second part of the diploma thesis. The hypotheses are analysed on the tennis data whether players make less effort in uneven tournaments, regardless of their position as favourite or outsider, than the theory presumes. The analysis of the above mentioned hypotheses was performed on the data from the Grand Slam tournaments in the years 2011 and 2012. Hypotheses are tested using both male and female data. The results obtained from analysis of the data confirm the hypotheses.

The thesis is concerned with relationships between progressive technological processes of spheroidal graphite cast iron’s production and their structural properties. The aim of the work is to explain causal relationship between parameters of the proposed manufacturing technology of the iron type given (involving selected variants of modification and inoculation of melt and the parameters of melt crystallization, solidification and cooling down in a mould), their structure and even chemical heterogeneity of elements in this structure. For close specification of presented relationships three-dimensional model of spheroidal graphite growth was used, which was developed at the Brno University of Technology, Faculty of Mechanical Engineering. Its usability in praxis has been verified on the basisis of the application of this model on experimentally acquired data. The U GRAFIT 20 model of the authors Stránský and Million counting segregation in the frame of eutectic cell has not still been used for prediction of segregation in real condition in greater extent. On the basis of the above mentioned model microsegregation within “on average” of the cell has been discovered during experimental melts. Microsegregation has been described by segregation and heterogeneity indexes. Calculated values of segregation and heterogeneity indexes have been compared with experimentally verified values. On the basis of comparison of calculated and measured values the possibility of further usage of the mentioned model in praxis has been explored.

Abstract:
Traumatic brain injury (TBI) and its associated neural and cognitive sequelae are of increasing interest in military populations. Blast-related TBI is becoming more commonplace in military Service Members and Veterans since Operation Iraqi Freedom/Operation Enduring Freedom/Operation New Dawn and their following conflicts. It is currently unclear whether blast-related injuries cause unique neural and cognitive deficits. The present investigation, in Study 1, aims to investigate the differences in blast-related and non-blast related TBI using traditional statistical techniques. In Study 2, this study will demonstrate the use of Qualitative Comparative Analysis (QCA) in diffusion tensor imaging data. QCA is a relatively new technique that examines configurations of variables that lead to a predefined outcome. QCA has the ability to uncover configurations of variables not yet considered in empirical literature, which may contribute new perspectives on the many different variables often associated with brain injury. Study 1 demonstrated no significant differences between uninjured and injured subjects in white matter integrity, and no differences between blast-related and non-blast related mechanisms. Study 2 demonstrated limited support for the use of QCA in diffusion tensor imaging. Evidence for the use of this method in other neuroimaging modalities is reviewed

Abstract:
Abstract A spatially local region of mechanical property heterogeneity is a source of scattering, by which a structure-borne mechanical wavefield is released as sound, to a surrounding fluid. We consider the case of a scatterer which is of the order of the size of the wavelength of a plate-wave field for a frequency which is below coincidence. A design strategy for reducing the strength of the scattered sound field in the fluid, at far-field distances from the scatterer, by adding a small-scale structure to the heterogenity, is presented. The design is accomplished in a wavelet-based phase-space. Emphasized is a significant distinction required of the added structure, depending on the heterogeneity applying to a measure of the local mass density or the local bending stiffness.

Abstract:
Angle-closure glaucoma, pigment dispersion syndrome, and intraoperative floppy iris syndrome (IFIS) are all ocular disorders that involve abnormal morphologies of the iris. In angle-closure glaucoma, for example, the iris bows anteriorly and impedes the natural flow of the fluid (aqueous humor), which then increases the intraocular pressure (IOP) leading to vision loss. The iris contour is determined by a combination of external stresses arising from the flow of the aqueous humor [1] and internal stresses due to the passive and active components of the constituent tissues. We have previously shown that the iris has a mechanical asymmetry [2] and that posterior positioning of the dilator muscle within the iris contributes to the anterior bowing during dilation [3]; however, the relative contributions of the individual components of the iris are unknown.

Abstract:
Metal fuelled sodium cooled fast reactors are known to have high breeding ratio and short doubling time. Due to these features they play a very important role in the energy scenario, where higher power growth is required. Large sodium cooled fast reactors have positive sodium void coefficient, which is considered to be undesirable feature even though reactor safety can be established for all design based accidents like loss of flow and transient over power accidents. These types of fast reactors, which have harder neutron spectra are having higher sodium void coefficient compared to ceramic fuelled fast reactors. In many of the safety analysis the total sodium void is calculated and it is used in the safely evaluation. However the sodium in the metal fuelled reactor has got three parts, namely bonding sodium, coolant sodium and the sodium in the inter space of subassembly hexagonal cans. In the reactor accident scenario the behavior of these three components of sodium will be different and will effect the sequence of the accident. The finer details, of the fuel sub assembly, are modeled in to Monte Carlo code and the sodium void coefficient is calculated for each of the component for the fuel zones. This study will be helpful in improving safety of the reactor and also reducing the conservatism in the safely features.

Abstract:
Citrated plasma from healthy individuals or fran patients with disseminated intravascular coagulation(DIC) was diluted, and elec-trophoresed on 11% SDS-PAG slabs after reduction.Subsequently, the electrophoretic pattern was Western-blotted onto nitrocellulose and,-after blocking with gelatine-, reacted with either:a)polyclonal antibodies to human fibrinogen,b)polyclonal antibodies to FPA, or c)monoclonal antibody to non-released FPA (gift from Dr.Nieuwenhuizen, Leyden, Holland).Visualization of fibrinogen-related material was then done with peroxidase-conjugated secondary antibodies.In normal plasma a heterogeneity of the Aa-chain which was substantially more pronounced than hitherto described was noted. This pattern of fibrinogen Aa-chain heterogeneity was even more noticeable in plasma from patients with DIC. The presence/absense of all appropriate fibrinolytic inhibitors during sampling of blood had no effect upon the Aa-chain heterogenity patterns described above. This picture of heterogeneity was also seen when unreduced plasma was electrophoresed on SDS-PAG(2.5%)/AGAROSE(0.5%) slabs.When comparing the patterns produced by the three different antibodies used for identification/visualization, it could be deduced that: l)The pattern observed was mainly due to Aa-chain heterogeneity, and that the N-terminus of almost all species of Aa-chains were intact, confirming earlier observations that cell- or plasmin -mediated proteolysis of this chain is mainly C-terminal; 2) The present technique allows extranely sensitive characterization of both reduced and non-reduced plasma fibrinogen in the presence of all other plasma proteins.
