Low-power low-area techniques for multichannel recording circuits dedicated to biomedical experiments
Authors: Kmon P. 
Published: September 2016

Abstract
This paper presents techniques introduced to minimize both power and silicon area of the multichannel integrated recording circuits dedicated to biomedical experiments. The proposed methods were employed in multichannel integrated circuit fabricated in CMOS 180nm process and were validated with the use of a wide range of measurements. The results show that both a single recording channel and correction blocks occupy about 0.061 mm2 of the area and consume only 8.5 μW of power. The input referred noise is equal to 4.6 μVRMS. With the use of additional digital circuitry, each of the recording channels may be independently configured. The lower cut-off frequency may be set within the range of 0.1 Hz–700 Hz, while the upper cut-off frequency, depending on the recording mode chosen, can be set either to 3 kHz/13 kHz or may be tuned in the 2 Hz–400 Hz range. The described methods were introduced in the 64-channel integrated circuit. The key aspect of the proposed design is the fact that proposed techniques do not limit functionality of the system and do not deteriorate its overall parameters.
Fuzzy interpretation for temporal-difference learning in anomaly detection problems

Published: September 2016

Abstract
Nowadays, information control systems based on databases develop dynamically worldwide. These systems are extensively implemented into dispatching control systems for railways, intrusion detection systems for computer security and other domains centered on big data analysis. Here, one of the main tasks is the detection and prediction of temporal anomalies, which could be a signal leading to significant (and often critical) actionable information. This paper proposes the new anomaly prevent detection technique, which allows for determining the predictive temporal structures. Presented approach is based on a hybridization of stochastic Markov reward model by using fuzzy production rules, which allow to correct Markov information based on expert knowledge about the process dynamics as well as Markov’s intuition about the probable anomaly occurring. The paper provides experiments showing the efficacy of detection and prediction. In addition, the analogy between new framework and temporal-difference learning for sequence anomaly detection is graphically illustrated.

Abstract
The paper presents an automatic approach to recognition of the drill condition in a standard laminated chipboard drilling process. The state of the drill is classified into two classes: “useful” (sharp enough) and “useless” (worn out). The case “useless” indicates symptoms of excessive drill wear, unsatisfactory from the point of view of furniture processing quality. On the other hand the “useful” state identifies tools which are still able to drill holes acceptable due to the required processing quality. The main problem in this task is to choose an appropriate set of diagnostic features (variables), based on which the recognition of drill state (“useful” versus “useless”) can be made. The features have been generated based on 5 registered signals: feed force, cutting torque, noise, vibration and acoustic emission. Different statistical parameters describing these signals and also their Fourier and wavelet representations have been used for defining the features. Sequential feature selection is applied to detect the most class discriminative set of features. The final step of recognition is done by using three types of classifiers, including support vector machine, ensemble of decision trees and random forest. Six standard drills of 12 mm diameter with tungsten carbide tips were used in experiments. The results have confirmed good quality of the proposed diagnostic system.

Authors: Blakiewicz G. , Jakusz J. , Jendernalik W. , Szczepański S. 
Published: September 2016

Abstract
In this paper, a tuning method of a resonant circuit suited for wireless powering of miniature endoscopic capsules is presented and discussed. The method allows for an automatic tuning of the resonant frequency and matching impedance of a full wave rectifier loading the resonant circuit. Thereby, the receiver tunes so as to obtain the highest power efficiency under given conditions of transmission. A prototype receiver for wireless power reception, fabricated in in AMS CMOS 0.35 μm technology, was used to verify correct operation of the proposed tuning. The prototype system produces a stable supply voltage, adjustable in the range of 1.2–1.8 V at a maximum output current of 100–67 mA, which is sufficient to power a typical endoscopic capsule.

Published: September 2016

AbstractThe idea of multiband development board designed to support and advance the technique of battery-less autonomous semi-passive RFID transponders is presented in the paper. The extra function of harvesting energy from the electromagnetic field of different radio communications systems, the ultra efficient power conditioner and the energy storage block are applied in the proposed construction. The facility of utilizing gathered energy is provided to support designers in developing applications of automatic object identification. Since the evaluation board is to work without a galvanic cell, the particular emphasis is put on the mechanisms that improve energy efficient operation of the whole electronic circuit. The construction principles and operation modes (charging, cold start, sleep with charging, sleep, measurement and cut-off) of the storage unit are described in depth in the paper. The preproduction batch of the demonstrators has been manufactured on automated assembly line at ELMAK Ltd. Company, according to the elaborated model. It confirms that the author’s demonstrator of the battery-less autonomous semi-passive transponder can be reproduced on an industrial scale. On the basis of the preproduction series, the performance parameters of the final product have been estimated. The presented study should significantly contribute to the RFID technique therefore the authors set up the evaluation process of marketing research and product commercialization.

Authors: Magnucka-Blandzi E. , Magnucki K. 
Published: September 2016

Abstract
The paper is devoted to buckling problem of axially compressed shallow cylindrical panels. Governing differential equations of the nonlinear theory of shallow cylindrical shells are analytically solved. Critical stresses and equilibrium paths of the panels with small curvatures are analytically studied. The formula of the critical stresses for almost flat, cylindrical panels is derived. The “shallowness” of the panel is given by the parameter α and formulae are derived for a range of this parameter. The range of values of sectorial angle for these panels is also defined.
Numerical Solution of Parabolic Problems Based on a Weak Space-Time Formulation
Authors: Larsson Stig , Molteni Matteo 
Published: September 2016

Abstract
We investigate a weak space-time formulation of the
heat equation and its use for the construction of a numerical scheme.
The formulation is based on a known weak space-time formulation, with
the difference that a pointwise component of the solution, which in
other works is usually neglected, is now kept. We investigate the role
of such a component by first using it to obtain a pointwise bound on
the solution and then deploying it to construct a numerical scheme.
The scheme obtained, besides being quasi-optimal in the

L

${L^{2}}$

sense, is also
pointwise superconvergent in the temporal nodes. We prove a priori error estimates and we present numerical experiments to empirically support our findings.

Published: September 2016

Summary
This experiment evaluated the effect of soil management systems on the vegetative growth potential of black currant (Ribes nigrum L.) cultivars. Three soil management systems were used: I – bare fallow i.e. continuous tillage; II – sawdust mulch, and III – black polyethylene foil mulch. Six black currant cultivars were included: ‘Ben Lomond’, ‘Ben Sarek’, ‘Titania’, ‘Čačanska Crna’, ‘Tisel’ and ‘Tiben’. The highest values of vegetative growth parameters were obtained in 'Čačanska Crna' and 'Ben Lomond' and the lowest in 'Ben Sarek'. Bare fallow and sawdust mulch treatments showed no differences in the tested parameters, whereas significantly lower values were recorded under foil mulch treatment.

Summary
The aim of this research was to investigate the microbial activity in forest soil from different sites under deciduous and coniferous trees in Serbia. One site on Stara planina was under beech trees (Fagus sp.) while another under mixture of spruce (Picea sp.) and Douglas fir (Pseudotsuga sp.). The site on Kopaonik was under mixture of beech (Fagus sp.) and spruce (Picea sp.) trees. The site on Tara was dominantly under fir (Abies sp.), beech (Fagus sp.) and spruce (Picea sp.). The total number of bacteria, the number of actinobacteria, fungi and microorganisms involved in N and C cycles were determined using standard method of agar plates. The activities of dehydrogenase and ß-glucosidase enzymes were measured by spectrophotometric methods. The microbial activity was affected by tree species and sampling time. The highest dehydrogenase activity, total number of bacteria, number of actinobacteria, aminoheterotrophs, amylolytic and cellulolytic microorganisms were determined in soil under beech trees. The highest total number of fungi and number of pectinolytic microorganisms were determined in soil under spruce and Douglas fir trees. The correlation analyses proved the existence of statistically significant interdependency among investigated parameters.

Authors: Kroča Jiří 
Published: September 2016

Abstract
The investigation of three streams in the Moravian part of the Javorníky Mts in 2003 and 2006–2009 brings the first records of Plecoptera in these mountains. A total of 28 species and were found (30 % of the recent fauna of the Czech Republic), among which species of the upper parts of streams predominate. This result corresponds to the nature of the habitat on which researches have been carried out. One endangered species (Leuctra cf. major), two vulnerable species (Dinocras cephalotes, Perla marginata) and one near threatened species (Leuctra quadrimaculata) were recorded. Comparing the recorded species to those of the neighbouring mountains, it can be assumed that the fauna of stoneflies of the Javorníky Mts may contain more than 40 species and can form a continuous transition between the Moravskoslezské Beskydy Mts and the Bílé Karpaty Mts (including the Vizovická vrchovina Highlands).

Global analysis of threat status reveals higher extinction risk in tropical than in temperate bird sister species
Authors: Reif Jiří , Štěpánková Klára 
Published: September 2016

AbstractGiven increasing pressures upon biodiversity, identification of species’ traits related to elevated extinction risk is useful for more efficient allocation of limited resources for nature conservation. Despite its need, such a global analysis was lacking in the case of birds. Therefore, we performed this exercise for avian sister species using information about their global extinction risk from IUCN Red List. We focused on 113 pairs of sister species, each containing a threatened and an unthreatened species to factor out the effects of common evolutionary history on the revealed relationship. We collected data on five traits with expected relationships to species’ extinction risk based on previous studies performed at regional or national levels: breeding habitat (recognizing forest, grassland, wetland and oceanic species), latitudinal range position (temperate and tropics species), migration strategy (migratory and resident species), diet (carnivorous, insectivorous, herbivorous and omnivorous species) and body mass. We related the extinction risk using IUCN threat level categories to species’ traits using generalised linear mixed effects models expecting lower risk for forest, temperate, omnivorous and smaller-bodied species. Our expectation was confirmed only in the case of latitudinal range position, as we revealed higher threat level for tropical than for temperate species. This relationship was robust to different methods of threat level expression and cannot be explained by a simple association of high bird species richness with the tropical zone. Instead, it seems that tropical species are more threatened because of their intrinsic characteristics such as slow life histories, adaptations to stable environments and small geographic ranges. These characteristics are obviously disadvantageous in conditions of current human-induced environmental perturbations. Moreover, given the absence of habitat effects, our study indicates that such perturbations act across different tropical environments. Therefore, disproportionally higher conservation effort in the tropics compared to the temperate zone is urgently needed.
On the methodology of feeding ecology in fish
Authors: Saikia Surjya Kumar 
Published: September 2016

AbstractFeeding ecology explains predator’s preference to some preys over others in their habitat and their competitions thereof. The subject, as a functional and applied biology, is highly neglected, and in case of fish, a uniform and consistent methodology is absent. The currently practiced methods are largely centred on mathematical indices and highly erroneous because of non-uniform outcomes. Therefore, it requires a relook into the subject to elucidate functional contributions and to make it more comparable and comprehensive science. In this article, approachable methodological strategies have been forwarded in three hierarchical steps, namely, food occurrence, feeding biology and interpretative ecology. All these steps involve wide ranges of techniques, within the scope of ecology but not limited to, and traverse from narrative to functional evolutionary ecology. The first step is an assumption-observation practice to assess food of fish, followed by feeding biology that links morphological, histological, cytological, bacteriological or enzymological correlations to preferred food in the environment. Interpretative ecology is the higher level of analysis in which the outcomes are tested and discussed against evolutionary theories. A description of possible pedagogics on the methods of feeding ecological studies has also been forwarded.
Knowledge management vs business process management in contemporary enterprises
Authors: Bitkowska Agnieszka 
Published: September 2016

Abstract
The main objective of this paper is to identify the system of knowledge management in contemporary process organizations in business process perspective, especially with regard to technological and social conditions. Methodology is based on literature analysis and case studies. The integration of knowledge management technologies, concepts and methods into organizational business processes is challenging research issue today. The concepts of knowledge management and business process management should be analyzed jointly in the contemporary enterprises. Despite of the growing interest among researchers and practitioners of the concept of the knowledge management referring to business process management there is a lack of articles in this area. Appropriate approach to the modelling of knowledge management processes, as well as the use of IT tools, and a motivation system are of key importance for the introduction of this solution in organizations.
Incremental Localization Algorithm Based on Regularized Iteratively Reweighted Least Square
Authors: Yan Xiaoyong , Yang Zhong , Liu Yu , Xu Xiaoduo , Li Huijun 
Published: September 2016

Abstract
Incremental localization algorithm is a distributed localization method with excellent characteristics for wireless network. However, its estimated result is generally influenced by the heteroscedasticity arising from cumulative errors and the collineation among anchor nodes. We have proposed a novel incremental localization algorithm with consideration to cumulative errors and collinearity among anchors. Using iteratively reweighted and regularized method, the algorithm reduces the influences of errors accumulation and avoids collinearity problem between anchors. Simulation experiment results show that compared with the previous incremental localization algorithms, the proposed algorithm obtains a localization solution which not only has high accuracy but also high stability. Therefore, the proposed algorithm is suitable for different deployment environments and has high adaptability.
Tropane alkaloids as substrates and inhibitors of human organic cation transporters of the SLC22 (OCT) and the SLC47 (MATE) families
Authors: Chen Jiayin , Brockmöller Jürgen , Seitz Tina , König Jörg , Tzvetkov Mladen V. , Chen Xijing 
Published: September 2016

Abstract
Tropane alkaloids and their derivatives are anticholinergic drugs with narrow therapeutic range. Here we characterize the organic cation transporters from the SLC22 (OCT1, OCT2, and OCT3) and the SLC47 families (MATE1 and MATE2-K) as potential mediators of the renal and extra-renal excretion, the two major roads of elimination of these substances. All analyzed compounds inhibited and the quaternary amine derivatives ipratropium and trospium were strongly transported by OCTs and MATEs. Overexpression of OCTs or MATEs in HEK293 cells resulted in an up to 63-fold increase in the uptake of ipratropium (K
m of 0.32 μm to OCT2 and V
max of 3.34 nmol×mg protein−1×min−1 to MATE1). The transcellular transport of ipratropium was 16-fold higher in OCT2-MATE1 and 10-fold higher in OCT1-MATE1 overexpressing compared to control MDCKII cells. Genetic polymorphisms in OCT1 and OCT2 affected ipratropium uptake and clinically relevant concentration of ondansetron and pyrithiamine inhibited ipratropium uptake via MATEs by more than 90%. This study suggests that OCT1, OCT2 and MATEs may be strongly involved in the renal and extra-renal elimination of ipratropium and other quaternary amine alkaloids. These substances have a notoriously narrow therapeutic range and the drug-drug interactions suggested here should be further critically evaluated in humans.
Structural and lipid-binding characterization of human annexin A13a reveals strong differences with its long A13b isoform
Authors: Fernández-Lizarbe Sara , Lecona Emilio , Santiago-Gómez Angélica , Olmo Nieves , Lizarbe María Antonia , Turnay Javier 
Published: September 2016

Abstract
Annexin A13 is the founder member of the vertebrate family of annexins, which are comprised of a tetrad of unique conserved domains responsible for calcium-dependent binding to membranes. Its expression is restricted to epithelial intestinal and kidney cells. Alternative splicing in the N-terminal region generates two isoforms, A13a and A13b, differing in a deletion of 41 residues in the former. We have confirmed the expression of both isoforms in human colon adenocarcinoma cells at the mRNA and protein levels. We have cloned, expressed, and purified human annexin A13a for the first time to analyze its structural characteristics. Its secondary structure and thermal stability differs greatly from the A13b isoform. The only tryptophan residue (Trp186) is buried in the protein core in the absence of calcium but is exposed to the solvent after calcium binding even though circular dichroism spectra are quite similar. Non-myristoylated annexin A13a binds in a calcium-dependent manner to acidic phospholipids but not to neutral or raft-like liposomes. Calcium requirements for binding to phosphatidylserine are around 6-fold lower than those required by the A13b isoform. This fact could account for the different subcellular localization of both annexins as binding to basolateral membranes seems to be calcium-dependent and myristoylation-independent.
Koncesívnosť v súčasnej Ruskej lingvistike
Authors: Sokolová Jana 
Published: September 2016

Abstract
The study focuses on the research of concessivity in two centres; namely in the Petersburg typological school and in the Moscow school of semantics. It presents the methodology and the results of the analyses of main representatives of the schools. Both schools address concessivity from the perspective of the semantics of concessive operators. In Russian studies, the main attention is given to the conjunction хотя (‘although’) and its elaborations are based on two directions: a) from the perspective of the semantics of causes and effects; b) from the perspective of the semantics of condition. An interpretative basis of the causal relations is formed by the semantic components ‘because’ (‘потому что’), ‘therefore’ (‘поэтому’) and ‘it causes’ (‘влияет’). Interpretations of the aspect of condition corresponds to the semantic component ‘if…so’ (‘если…то’).
