This paper presents a novel deep learning-based framework for translating a motion into various styles within multiple domains. Our framework is a single set of generative adversarial networks that learns stylistic features from a collection of unpaired motion clips with style labels to support mapping between multiple style domains. We construct a spatio-temporal graph to model a motion sequence and employ the spatial-temporal graph convolution networks (ST-GCN) to extract stylistic properties along spatial and temporal dimensions. Through spatial-temporal modeling, our framework shows improved style translation results between significantly different actions and on a long motion sequence containing multiple actions. In addition, we first develop a mapping network for motion stylization that maps a random noise to style, which allows for generating diverse stylization results without using reference motions. Through various experiments, we demonstrate the ability of our method to generate improved results in terms of visual quality, stylistic diversity, and content preservation.


A systematic study of acoustically induced birefrigence in castor oil is described. Particular emphasis is placed upon the evaluation of a measuring technique based upon a polarization analysis of the Fraunhofer optical diffraction spectrum. Results obtained using this measuring technique are compared with results of measurements made in the optical nearfield.


Abstract Eight species of the family Piophilidae are found in the mainland Ukraine. Five of them, Allopiophila luteata (Haliday, 1833), Parapiophila vulgaris (Fallén, 1820), Protopiophila latipes (Meigen, 1838), Stearibia nigriceps (Meigen, 1826), and Neottiophilum praeustum (Meigen, 1826), are recorded from the first time from Ukraine. Two species, Mycetaulus bipunctatus (Fallén, 1823) and Prochyliza nigrimana (Meigen, 1826), have been previously recorded only from Crimea.


ABSTRACT We demonstrate a standoff system based on quartz-enhanced photoacoustic spectroscopy technique for the concentration measurements of atmospheric ozone and methane. The technique is a modified version of Photoacoustic spectroscopy. Two primary features of this technique are the employment of a tunable quantum cascade laser and a resonant quartz-crystal tuning fork detector. Both of these features facilitate simultaneous sensing of multiple molecular species. External-cavity quantum cascade laser having a spectral range from 7 to 10 micron is used. Diurnal concentration variations of methane and ozone are estimated for open-path up to 25 m. The ambient methane and ozone concentration maxima were observed to have values of 3.5 parts per million by volume and 140 parts per billion by volume, respectively. Finite-element mesh-based software is used to simulate the Eigen frequency of the tuning fork sensor. High-resolution transmission molecular spectroscopic database of atmospheric gases and the real-time gas concentration data from the Delhi Pollution Control Committee have been used as references.


Whether public administration could have rights has been a hot issue in the study of the public field. The traditional viewpoint thinks the public field should abandon the individual rights, namely the public administration refuses rights. However, in author's view, the individual rights in the public administration should be safeguarded more actively rather than be abondoned simply. The public administration needs the right. Only by carrying on system innovation in government and ensuring the masses of administrative personnels' rational rights will the administrative reform have new break-through, and there is a new situation in the development of the public field.


The disposal of waste electrical and electronic equipment (WEEE) into landfill is no longer acceptable in most countries. WEEE contains toxic materials which cause environmental damage when they leach from landfill, but it also contains significant amount


Drawing on the concepts developed in the external governance literature this paper argues that
the conclusion of the Schengen Association Agreement symbolises a qualitative change in the
bilateral relations between the EU and Switzerland. The argument on the qualitative change in
the intensity of relations is developed by comparing the situation in Schengen related matters
before and after the conclusion of the Swiss Schengen Association Agreement. Although the
regulatory boundary was formally not shifted prior to the conclusion of the Schengen
Association Agreement, various forms of policy transfer led to a high degree of policy
convergence. In contrast hereto the organisational boundary was only 'tentatively' shifted in
the pre-Schengen era owing to the fact that Switzerland remained excluded from the key
implementation networks (SIS, Dublin). The conclusion of a dynamic integration treaty in
Schengen matters shifts the EU's regulatory boundary towards Switzerland in an
unprecedented manner, a process that has been accompanied by a multiplication of
possibilities for organisational inclusion. The article concludes by critically reflecting on the
limited exportability of this advanced form of 'flexible integration'.


Single-wall carbon nanotubes (SWNTs) can be fabricated either metallic (m) or semiconducting (s). A cross-junction between an mand s-type SNWTs generates a structure with field effect transistor (FET) behavior [1, 4]. In this way, both ptype and n-type FETs are realizable (a p-type FET is ON when input is "0", while an n-type FET is ON when input is "1"). Moreover, these structures can be affixed on top of DNA origami [2, 5].


The objectives of our investigations are to describe the variation by mutations of stem architecture of the main groups of modern Ukrainian winter wheat varieties (8 varieties) due to their interactions with dose specific. Agronomic-value traits like as general short stem, dwarfs and semi-dwarfs have been investigated too. New perspective mutant lines have been obtained in terms of investigation. Main components for mutation breeding successful was genotype-mutagen interaction (due to factor analyses). By sensibility (in sense of number of mutations and type of mutations) genotypes can be subdivided on two groups. At the first group only varieties, which created with gamma-rays were observed. Gamma-rays were not useful for obtaining mutations by plant architecture for radiomutants varieties. Higher level of short-stem and semidwarfs mutation were inducted by 200 – 250 Gy doses, while for dwarfs in spite of dwarfs, which were observed more after 250 Gy. Semi-dwarfs as mutations significance responded to gamma-rays action by changes with doses.


Acetophenone-formaldehyde resin was synthesized by polycondensation of acetophenone and formaldehyde with NaOH as catalyst.The effect of molar ratio of formaldehyde and acetophenone,the amount of NaOH,reaction time on softening point and hydroxide value of acetophenone-formaldehyde resin was studied.The resin was characterized by FT-IR and ~1H-NMR.It was found that acetophenone-formaldehyde resin with softening point of 80.0℃ and hydroxide value of 23.3 mgKOH/g was prepared when the molar ratio of formaldehyde and acetophenone was 1∶1,the amount of NaOH was 3.0 wt% and reaction time was 7 hours.The FT-IR and ~1H-NMR results showed that the α-H of the methyl of acetophenone reacted with formaldehyde by way of polycondensation.


Leaf shedding (LS) of 3 avocado (Persea americana Mill.) clones ('Northrop 28/5', 'Fuchs 20' and 'Nahlat 7') differing in rooting ability was studied. Two distinct processes, leaf blade senescence and formation of the abscission layer, were found to be associated with LS. The rate of these processes differs among the 3 clones, and their combination determines the speed of LS. Leaf senescence was simulated by measuring chlorophyll destruction over time in leaf discs incubated in the light. The speed of abscission layer formation was estimated by measuring the time required for petioles to shed from incubated internodes. The results obtained in these tests were in agreement with the behavior of LS from cuttings of the 3 clones under mist. Auxin and cytokinin alone, or in combination, as measured in the 2 test systems, affected these leaf blade senescence and abscission layer formations at different rates. Six cuttings of the clone 'Fuchs 20' were sprayed weekly with combinations of NAA and BA. The optimal combination (1.10-4 m NAA + 5.10-4 m BA) caused a significant delay in LS and improvement in rooting. Relatively simple tests of leaf senescence and petiole abscission are discussed as potential methods for predicting rooting ability of leafy cuttings.


Simulation methods become more and more important in practical applications of scheduling, analysis and optimisation of manufacturing processes. One consequence is that the event discrete simulation systems and their application become part of the fundamentals of engineering education, even if the students should not become specialists in simulation methods. In our paper we show how the simulation of manufacturing processes can be used to make the theory clearer. The simulation models are simple but the need further development towards more complex and more practical models becomes apparent. This paper is also a field report about experiences with the simcron MODELLER in education.


Purpose In a clinical study, percutaneous microwave coagulation therapy (PMCT) was administered to evaluate this method as a therapy option for liver cancer. Methods HSE 8M PMCT equipment was utilized at 2450 MHz in frequency. Clinically, 51 cancerous nodules of 32 patients were treated, and then the results were evaluated using Levovist, 3 D ultrasound, and Lab findings. Results Clinically, after PMCT, all of 51 nodules had smaller size and disappearance or reduction of blood flow. AFP dropped in 16/20 patients with hepatocellular carcinoma (HCC). Among them, one patient's AFP had a decrease of nearly 30 thousand units. The efficacy of PMCT was good without severe complications. Conclusion ①Ultrasound guided PMCT is one of effective methods for the treatment of liver cancer; ②Paying much attention to the coagulation of main branches of tumor vessels has a better result of treatment; ③LEVOVIST contrast should be a gold standard for evaluation of treatment efficacy; and ④3 D US images accurately reflect true coagulation volumes in PMCT.


1* Introduction* In [4] (cf. also case V page 256 of [1]) J. Herbrand provides a decision procedure which is equivalent to a decision procedure for determining for a fixed contradiction C and for any first order prenex formula Γ whose matrix is a conjunction of signed atomic formulas, whether Γ—>C is valid. In this paper we define a class a of first order formulas and then provide a decision procedure for determining for any first order prenex formula Γ whose matrix is a conjunction of signed atomic formulas and and member Δ of the class, whether Γ —> Δ is valid. Although the class of formulas Δ that we consider is rather large, it is clear that some restriction is necessary since a decision procedure for the class itself is obtained by using for Γ a single propositional parameter that does not occur in Δ. The formulas we consider are those of any system of pure first order predicate calculus without equality and without function symbols. We use V, Λ, Ί , and —> for the propositional connectives disjunction, conjunction, denial, and the conditional, respectively. The symbols Γ, Δ, Γo, Δo, Γu Δlf shall range over arbitrary formulas, P, Q, P19 Qlf over prefixes, and M, N, Mlf Nlf over matrices. A propositional parameter or predicate parameter together with its attached individual variables or individual parameters will be called an atomic formula. An occurrence of an atomic formula in a formula Γ is called an atomic part of Γ. Two prenex formulas are similar if their matrices differ only in the symbols occupying individual variable places of the atomic formulas. Two prenex formulas are congruent if they differ only by equivalent replacements of bound variables. We indicate that Δ is a logical consequence of Γ by writing Γ\=4. If Γ\=A then there exists a symmetric L-deduction of Δ from Γ as described in [2]. For any formulas Γ and Δ an L-deduction of A from Γ is an ordered (n + 1)tuple <(Γ0, , Γny where ΓQ = Γ and Γn = Δ, together with a specification of how, for any m < n, Γm+1 results from Γm by an application of an L-rule. The reader is referred to pages 252 and 253 of [2] for the definitions of the eleven L-rules. An L-deduction is symmetric if and only if the order in which the different kinds of L-rules are applied satisfies conditions (iii) through (vi) on page 257 of [2] In addition, for convenience, we require that a symmetric L-deduction have exactly one application of the operation matrix change.


Inadequacies in sensor and image processing technology have limited the capabilities of autonomous robotics in complex environments, while tedium and fatigue are commonly encountered when purely manual teleoperation is used. Therefore, attention has been increasingly focused on the integration of human and machine control for remote operations. A previously introduced method of assisted teleoperation, consisting of the variable mapping of velocity commands from the master to slave manipulator using uncertain environmental data, is briefly reviewed. The new method is adapted for the task of maneuvering a manipulator within an enclosed cylindrical environment. A model is used to create a mapping from master to slave workspaces to allow the operator to move around the curved surface easily while avoiding unintended impacts with the wall. Experiments were developed which required fine positioning of the end-effector near the wall, and the results demonstrated the increase in efficiency of task completion and reduction of operator fatigue and skill requirements.


Analysis of results of endoscopic prevention of rebleeding from varices of the esophagus in 37 patients with the syndrome of portal hypertension during the period from March 2003 to March 2011 is presented. In the study group of patients underwent endoscopic ligation of veins under ultrasound guidance, followed by argon plasma coagulation of the lower third of the esophageal mucosa. In the control group endoscopic ligation was performed using the standard method. In this case, we have noted decrease in the frequency of rebleeding from esophageal veins from 60% in the control group to 29,4% in the intervention group of patients in the period of observation from 12 to 18 months.


Search and rescue operations play a vital role in saving lives in emergency situations. Knowing the exact latitude, longitude coordinates and directional angles can ensure effective and efficient operations when search and rescue personnel are operating in remote or hazardous environments. This paper presents the design and implementation of a search and rescue device based on magnetic compass. The device uses ESP8266 as the primary control module, combining GPS module for positioning and magnetic compass module for angle of acquisition. The information collected is corrected and transmitted to ESP8266 to provide feedback, which is displayed on the OLED screen to search and rescue personnel. The test results showed that the device performed well in all of the selected test scenarios, with an average accuracy of 0.61°for directional angle data and 1.17 meters for latitude and longitude coordinate data. This improved search and rescue device can improve search and rescue operations and increase the chances of successful rescues.

The purpose of this study is to examine effects of smart phone exercise application use motivation on leisure satisfaction. In order to achieve the above purpose, a questionnaire form was developed and distributed to total 300 smart phone exercise application users whose smart phone was produced. Next, total 287 valid and complete sheets of questionnaire form were used for final data analysis. Based on these procedures, this study could come to the following findings: This study used multiple regression analysis to determine potential effects of smart phone users' motivations to use exercise application on their leisure satisfaction(physical satisfaction, psychological satisfaction and social satisfaction) after use of exerciser application. As a result, it was found that health orientation, convenience and salience had positive effects on physical satisfaction. The health orientation and social orientation had positive effects on their psychological satisfaction and social orientation and salience had positive effects upon their social satisfaction.


Over-the-top (OTT) streaming growth is driven by the increasing number of wireless connected devices such as tablets and phones. An enabler for using these devices is adaptive bitrate (ABR) streaming that allows devices to select at each moment the stream quality that best fits the available bandwidth. The overall experience is highly dependent on the bandwidth estimation. The current approach to bandwidth estimation in HTTP-based ABR players is challenged by the evolution toward low-latency protocols (DASH CTE—Dynamic Adaptive Streaming over HTTP—Chunked Transfer Encoding) or (HLS LL—HTTP Live Streaming—Low-Latency), which result in micro-burst of traffic. Indeed, estimation at the client side, at the HTTP level, relies on the assumption that a relatively large segment of data is available and can be sent at the link speed, which is not the case anymore with low-latency protocols. To address this issue, we propose a novel scheme Server-Side Segment Selection for streaming (S4S), which allows players to interact with an S4S-enabled server to improve the overall experience. First, bandwidth estimation is done at the server side, using transport's congestion control sender-side stats, leading to more precise estimates even in the presence of small burst, especially when using modern congestion control algorithms such as Bottleneck Bandwidth and Round-trip propagation time (BBR) or Performance-orientated Congestion Control (PCC). Second, we define a protocol for allowing the network to control the bandwidth versus quality tradeoff.


Abstract Chicken gizzards were purchased from three retail stores and one processing plant. Studies were conducted to compare swab and rinse methods for microbial analysis of gizzards. The total, mold and yeast, coliform most probable number, staphylococcus 110 medium counts, and shelf-lives of gizzards from each store were enumerated and compared. The possible extension of shelf-life of raw gizzards by frozen processing during distribution was investigated. Ready-to-cook gizzards had an average weight of 26.39 g with standard deviation of 6.14 g. Variation in gizzard sizes had no significant effect (P A similar spoilage pattern was observed for the prefrozen and non-frozen gizzards. The shelf-lives of gizzards from three retail stores ranged from 2.41 to 3.92 days. Higher initial counts resulted in shorter shelf-life. Freezing of the products during transportation extended their shel-flives in retail stores for approximately 4 days.

Experimental hepatoma of the rats was induced by chronic administration of 3'‐methyl‐dimethylamino‐azobenzene. The folate level of the hepatoma‐bearing rats tended to be low as compared with that of normal controls, and the co‐existence of folate deficiency and reduced motor nerve conduction velocity of the dorsal nerve trunks appeared not uncommon. The hepatoma‐bearing rats revealed the disturbance of serine to glycine conversion in serum, and folate administration to them prevented electrophysiological neuropathy along with normalization of serine to glycine conversion. Therefore, the reduced motor nerve conduction velocity could be at least in part the result of a metabolic impairment due to folate deficiency.


Infantile hemangioma (IH) is a common benign endothelial cell tumor in infants and young children, sometimes accompanied by potential complications, and may develop into malignant tumors. Hemangioma endothelial cells (HemECs) are one of the main components of IH. Podophyllotoxin (PPT) has been reported to have many pharmacological activities, especially anti‐tumor, but its high toxicity, poor water solubility, and serious gastrointestinal side effects limit its clinical application. In this study, we have designed and synthesized 20 ester derivatives by introducing Boc‐amino acids or organic acids at the C‐4 position of podophyllotoxin through esterification reactions. The cytotoxicity of these compounds was evaluated on HemECs. Changes in cell proliferation and apoptotic signaling pathways were studied by DAPI staining, colony formation assay, migration assay, measurement of reactive oxygen species (ROS) levels flow cytometry, and Western blot analysis. We found that eight of the compounds were more potent than PPT. Of these, compound V‐31 was the most active (IC50 = 0.079 ± 0.0049 µM). Further research indicated that compound V‐31 inhibited its proliferation and migration, increased the level of ROS in cells, and induced apoptosis by downregulating p‐PI3K, p‐Akt, and Bcl‐2, and upregulating cleaved caspase‐3 and Bax. Our research provides the first insight into the application of PPT derivatives in HemECs, may provide an effective medicine for IH treatment.


Friedrich Dessauer is a technological philosopher that there is most influence in Germany during the first half of the 20~(th) century.His main thought about technological philosophy is in the book "The Controversy Concerning Technology"(1956).The book is to aim at hypostatic standpoint causing by the book "Philosophy of Technology"(1927).In the book,he did to complement the theory of "the fourth realm",extend meaning of Comte's "three realms"——science,morals and art,and still insists to think that the invent is just to find a technique exists in the nature with the latent form,and it is the God to create a life time activity continuously.Here he illustrates technical innate character,invents,the form of technical being and it's historical character,character of technique object,technical influence and contacting etc.He stably answers the technical viewpoint and dispute from scholar before him and at the same time.

In their publication based on a case–control study of pleural mesothelioma in Casale Monferrato, Ferrante et al 1 reported associations with occupational and non-occupational (household and residential) exposure to asbestos. From a qualitative point of view, these results are hardly surprising since similar findings have been reported in several other populations with heavy asbestos exposure (for review see ref. 2).

The main emphasis of the publication, however, rests on quantitative estimates of these associations. However, the results suffer from important limitations, and these limit their interpretation. Response rate was 89% among cases and 63% among controls, and the proportion of interviews …


This paper presents an augmented reality (AR) interface for robot programming of pick-and-place tasks as well as assembly operations. The aim of the AR interface is to increase the intuitiveness and ease of robot programming. Marker tracking is used to automate sensor registration for easier workspace setup. Object recognition is employed to transform robot programming from an absolute coordinate system to an object-based system. This transformation provides flexibility to robot programming as the AR interface can be applied to workspaces that are configured differently to accomplish the same task. A spatially immersive display method is adopted to provide a projection-based direct overlay virtual workspace, so as to give users a better frame of reference in relation to the real workspace.


The task of document summarization became more pressing as the information volume increased exponentially from news websites to scientific writings. As such, the necessity for tools that automatically summarize written text, while keeping its meaning and extracting relevant information, increased. Extractive summarization is an NLP task that targets the identification of relevant sentences from a document and the creation of a summary with those phrases. While extensive research and large datasets are available in English, Romanian and other low-resource languages lack such methods and corpora. In this work, we introduce a new approach for summarization using a Masked Language Model for assessing sentence importance, and we research several baselines for the Romanian language including K-Means with BERT embeddings, an MLP considering handcrafted features, and PacSum. In addition, we also present an evaluation corpus to be used for assessing current and future models. The unsupervised methods do not require large datasets for training and make use of low computational power. All of the proposed approaches consider BERT, a state-of-the-art Transformer used for generating contextualized embeddings. The obtained ROUGE score of 56.29 is comparable with state-of-the-art scores and the METEOR average of 51.20 supersedes the most advanced current model.


The basic structure and the main design points of the runner system of the injection moulds for thermoset and rubber parts were introduced. The conditions for heat balance of the runner system based on both the adiabatic flowing model and the isothermal flowing model were analyzed. Practical calculations of heat balance and heat transfer in the design of the runner system were proposed.


Virtual try-on technology that replaces a customer's wearing with arbitrary garments can significantly improve the online cloth shopping experience [anonymous 2021; Han et al. 2018; Yang et al. 2020]. In this work, we present a real-time image-based virtual try-on system composed of two parts, i.e., photo-realistic clothed person image synthesis for the customers to experience the try-on result and garment capturing for the retailers to capture the rich deformations of the target garment. Distinguished from previous image-based virtual try-on works, we formulate the problem as a supervised image-to-image translation problem using a measurement garment, and we capture the training data with a custom actuated mannequin.


Parishioners (n = 130) of an Episcopal church in New York City participated in a survey to explore the relationship between the religiosity, death acceptance, and death anxiety. Among the four different types of religiosity measured by the Rohrbaugh and Jessor scale, theological religiosity was the only one to have a significant effect on death acceptance and death anxiety. Belief in God's existence (r = −0.27), and belief in the afterlife (r = −0.25) were both negatively correlated with death anxiety (p < 0.01), and positively correlated with death acceptance (respectively, r = 0.21 and r = 0.22, p < 0.05). The effects remained significant even after controlling for a number of demographic variables using multiple regression procedures. Being a woman was the only demographic variable that was significantly correlated with greater anxiety about death. On average, women displayed significantly higher levels of death anxiety (M = 8.1, SD = 2.8) than men (M = 6.2, SD = 2.9).


The organization pattern of P2P (Peer-to-Peer), has become an important form of internet application of new generation because of its such features, as good expansibility, fault tolerance and high-performance. The persistent data storage is the key to inhibiting the development of global storage system, and is also difficulty issues of the research.This paper describes a design idea and a system architecture of distributed storage system established on P2P in detail, and proposes an effective mechanism according to resource topic and predicted network distance for node grouping, and verifies the persistent data storage performance of P2P global storage system.


Based on the understanding of aesthetics as the study of all processes and activities related to aesthesis in his original etymological sense as «sensibility», this paper argues that an evolutionary approach must follow the evolution of aesthesis from its inception. A degree of sensibility may perhaps be traced already at molecules sensing borders in DNA replication. The next stage, which may be defined as "cyto-aesthesis", refers to evidence of cells' actions to antigens, virus, enzymes or bacteria and other significant elements in the intercellular fluid by their receptors' sensibility to ligands. Darwin explored plants' irritability specifically at their tendrils and petioles and there are studies on their sensibility to surface, nutrients, touch, water, temperature, seasonal cycles, color, gravity, and light. All animal species, including human beings, have evolved a keen sensitivity to predators and mates upon which their survival depends following evolutionary priorities and conditions. There is consequently no particular experience that we may call «aesthetic experience», a redundant term, since the whole spectrum of activities and effects of various species' sensibility involves experiencing the world, namely, aesthesis.

All synchronous systems use a clock distribution network covering a large section of the integrated circuit and handling the fastest frequencies of the device. In this work, the performance of interconnected and coupled ring oscillator arrays working as clock distribution networks is analyzed. The use of interconnected three-delay stages rings are proposed even for chip lengths from 4 to 24 mm. Typical 3.3 V AMS 0.35 mum CMOS N-well process parameters were used for the design and fabrication. Experimental results of 16 non-expanded and expanded interconnected ring oscillators agree with simulation.


Landslides due to earthquakes in Colombia have been historically reported since 1530 when ground cracking, soil movements and liquefaction events were induced by an earthquake which magnitude has not been defined. Since then more than thirty earthquakes have been identified to have produced landslides in the country, in some cases consequences related to landslides have been more significant than those due to direct effects of the earthquake itself. The author has compiled a database of landslides induced by earthquakes in Colombia from which relationships between earthquake magnitude and landslide characteristics have been explored. It has been found that residual and volcanic soils are very susceptible to landslides by seismic. Some cases show to have induced liquefaction on alluvial deposits of the main rivers and sea shores. Failure of landfills has also been observed. Relationships between maximum epicentre distance to landslides and area affected by landslides and earthquake magnitude were found. The influence of precedent climatic conditions was observed in reducing the seismic load required to induce landslides and in the difference on slide mechanism.


(1)The laminar distributions of acid and alkaline phosphatase in the visual, motor and somatosensory cortices of the rabbit have been determined by quantitative microchemical methods. (2)The patterns of laminar distribution of ACP and AKP in the visual,motor and soma- tosensory areas have been found to be fundamentally similar to each other.The enzyme activity decreases as it goes from layer Ⅱ-Ⅲ down to the white matter.The peak of the activity seems to be located in layer Ⅱ-Ⅳ.The enzyme activity of layer Ⅰ is much higher than that of the layer Ⅵ and white matter. (3)The laminar distribution of ACP and AKP in the cerebral cortex follows a similar pattern,although the absolute quantity of the AKP is much less than that of ACP in the same cortical layer. (4)The absolute level of acid phosphatase activity was found to be somewhat higher in the motor cortex than in the visual and somatosensory cortices


Sputtered nano devices based on chalcogenide glasses have been studied. Physical, chemical and electrochemical characteristics are presented. Cd-Ag-(Ge28Sb12Se60) and CdAg-(As2S3) miniaturised ion selective electrodes exhibit near-Nernstian response with a low detection limit versus cadmium (+II) species in solution. High reproducibility and high selectivity are observed. This is a favourable feature for measurements in natural water and waste effluents. Moreover, non-destructive in situ electrochemical technique that is capable of characterizing interfacial reactions has been successfully used. Indeed, Electrochemical Impedance Spectroscopy technique was used to provide information on fundamental processes that occur at the electrode – solution interface.

String Matching algorithm can be used in implementing a Network Intrusion Detection System (NIDS). With the String Matching algorithm and some optimizations, additional security measures, and complementing algorithms, NIDS could contribute in protecting systems connected by networks from suspicious activities by detecting such activities from the network traffic. In particular, String Matching is used in matching incoming or outgoing traffic with some predefined known malicious codes, which NIDS will alert if a match is positive. Keywords—algorithm, NIDS, security, string matching


Object: The purpose of this article is understanding the mixed application of marketing and psychology when creating resources for direct stimulation of the consumers' brain and in such way, it can persuade over their buy decisions. Methodology: Results are obtained from the recapitulation and synthesis of information whose resources settle in the fusion of marketing and psychological sciences related to the consumer. Findings: Application of neuro-marketing techniques help to know the consumer, allowing the creation of advertising focused with stimuli directly focalized into their desires and needs. Likewise, the process of decision making in the brain can take place conscious and unconsciously: for both ways, the response of the consumer is different and requires several stimuli. Conclusion: Stimulation of emotions in advertising campaigns as a marketing strategy is an important resource to create a link with the consumer. Hence, this will develop the process of buying because of emotivity, but not because of a rational, decision-making process.


This article is concerned to establish the extent to which accountability to the public, in relation to the further education system in Northern Ireland, is founded on tacit understandings and negotiated arrangements which involve acknowledgement of the role of professionals but which largely fail to address the identified socio-economic needs of the community. An investigation into accountability must consider the beliefs of individuals in Northern Ireland to be as important an area of study as are the forms of institutions. Giddens (1984, p. 25) has warned against the acceptance of reductive conceptions of institutions which fail to take account of the knowledgeability of agents and the consequent attribution of agency to structures rather than to individuals:


Introduction The most commonly-used method to assess progenitors and hematopoietic stem cells (HSC) present in a graft is the enumeration of phenotypically-defined CD34þ cells. A number of manuscripts, editorials and letters published recently in the Journal of Hematotherapy have addressed standardization methods for CD34þ cell determination [1– 7]. Even though higher numbers of CD34þ cells in the graft correlate with earlier white blood cell (WBC) engraftment and platelet engraftment [8,9] the CD34þ cell population is still extremely heterogeneous and contains a wide range of progenitors, from HSC to single-lineage committed progenitors. There is mounting interest in ex vivo manipulation of CD34þ cells, from ex vivo expansion of primitive progenitors and production of precursors, to the introduction of novel genetic material in HSC [10–14]. A number of culture systems have been described in which progenitors can be expanded and in which retroviral vectors can be introduced in CD34þ cells. However, transplantation of ex vivo manipulated progenitors in humans, as well as xenogeneic immunodeficient animals, has taught us that, although phenotypically-defined CD34þ cells or phenotypicallydefined primitive subsets of the CD34þ cell population can be maintained/expanded for several weeks, ex vivo manipulation for more than 4–7 days results in a dramatic loss of stem-cell capacity [15]. Although there is in vitro evidence that retroviruses can be introduced in > 50% of CD34þ cells, transplantation of such retrovirally-marked CD34þ cells in humans indicates that few, if any, vector-containing cells are detected after transplantation [16]. Therefore, the phenotypic characterization of primitive cells as CD34þ is far from sufficient and assays that can more accurately assess the fraction of progenitors with stem-cell characteristics within the CD34þ population are needed. A number of assays that evaluate CD34þ subpopulations which have more immature characteristics than the majority of the CD34þ population, are currently being used in research laboratories. In this overview, we will describe a number of assays developed in individual investigators' laboratories that assess primitive human progenitors and, possibly, HSC. We have purposefully chosen to keep this review descriptive and not to recommend one or more assays to be adopted in the clinical setting for the following reasons: n First, assessment of the absolute frequency of primitive progenitors in a given cell population using similar assays in individual laboratories differs considerably. This may, in part, be due to minor differences in culture conditions and, in part, to differences in the interpretation of colony growth. Unless these culture assays are standardized, as has been done for the phenotypic determination of CD34þ cell number, comparison between different laboratories will remain difficult. n Second, it still remains to be determined which assays currently available accurately assess the number of repopulating HSC in a graft. n Third, the inability of the majority of the assays to provide a 'real time' answer to the question as to whether HSC are present or preserved, detracts from their clinical usefulness. However, comparisons between 'stem cell content' in a given cell population obtained in the research setting and clinical-transplantation results will eventually lead to improved clinical therapies.


Background: Cases of osteomyelitis of maxilla were reported as a rare presentation. But osteomyelitis involving multiple cranial bones is a rarest of rare case. Here we present a case of 65 year old male, who presented with features of multiple discharging sinuses intraorally, externally over left cheek and left post-auricular region. On evaluation, the condition was found to be chronic pyogenic osteomyelitis involving maxilla, zygoma and temporal bones and odontogenic in origin. AIM: We have decided to report this interesting case because of its extensive involvement of multiple cranial bones in this antibiotic era and complete resolution of infection was gained with antibiotic therapy and surgical treatment.


We rebuilt Racket on Chez Scheme, and it works well—as long as we're allowed a few patches to Chez Scheme. DrRacket runs, the Racket distribution can build itself, and nearly all of the core Racket test suite passes. Maintainability and performance of the resulting implementation are good, although some work remains to improve end-to-end performance. The least predictable part of our effort was how big the differences between Racket and Chez Scheme would turn out to be and how we would manage those differences. We expect Racket on Chez Scheme to become the main Racket implementation, and we encourage other language implementers to consider Chez Scheme as a target virtual machine.


In recent years, there has been a gradually growing emphasis on the protection of wilderness in Iceland. This is highlighted in the current preparation of a new national park in the Icelandic central highlands, which will become Europe's largest national parks. However, in order to protect the wilderness, a mutual understanding, both on what it is and where it is, is needed. This paper seeks to evaluate Icelanders' perception and understanding of wilderness. Furthermore, to assess the value of wilderness for the Icelandic public and determine what lies behind the valuation, an online survey aided by maps from Google Earth and photographic scenarios of different landscapes was sent out to a nationally representative sample of Icelanders. The survey respondents mapped their perceived scope of Icelandic wilderness and furthermore chose between several landscape scenarios they thought most and least suited to their perception of wilderness. The results show that nearly all land located above the 300 m elevation line is perceived as wilderness, reflecting the country's uninhabited highlands areas. The results also show that for the general public in Iceland it is chiefly an open and vast landscape, uninhabited areas, and the absence of anthropogenic features that bestow an area with the status of wilderness. The results demonstrate that any sign of anthropogenic interference, aside from archaeological remains, decrease Icelanders' perception of wilderness. Moreover, despite being mostly categorized as urbanists or neutralists according to the purism scale, the majority of Icelanders still consider services, such as petrol stations, hotels, shops, restaurants, and diverse leisure services, along with energy production, to negatively impact the value of wilderness. Most Icelanders thus seem to regard wilderness as a valuable asset from the economic, cultural, and environmental perspectives, which underscores its uniqueness.


Background Pembrolizumab is a standard of care for the treatment of unresectable or metastatic melanoma and an adjuvant treatment of melanoma with involvement of lymph node(s) following complete resection. However, new treatment options are needed to reduce the tumor burden before surgery and improve overall outcomes in patients with advanced melanoma. Methods MK-3475-U02 is a phase 1/2, rolling arm, multicenter, open-label, adaptive design study to evaluate the safety and efficacy of investigational agents with or without pembrolizumab or pembrolizumab alone for the treatment of melanoma. Patients will be enrolled in 1 of the 3 substudies. Substudy 02A will include patients with programmed death-1 (PD-1)–refractory melanoma (progressed after ≥2 doses of anti-PD-1/programmed death ligand-1 [PD-L1] therapy) randomized equally to treatment arms evaluating ≥1 investigational agent(s) with or without pembrolizumab. Enrollment is planned for up to ~100 patients per arm.Substudy 02B will include patients with unresectable stage III or stage IV melanoma not amenable to local therapy. Patients will be randomized 2:1 to combination (≥1 investigational agent(s) with or without pembrolizumab) or monotherapy (pembrolizumab alone) stratified by baseline lactate dehydrogenase status (normal/elevated) and prior adjuvant therapy with a PD-1 inhibitor (yes/no). Enrollment is planned for ~90 patients in the combination arm and ~45 in the control arm.Substudy 02C will include patients with stage IIIB/IIIC/IIID melanoma who are candidates for neoadjuvant therapy. Patients will be randomly assigned to combination (≥1 investigational agent(s) with or without pembrolizumab) or monotherapy (pembrolizumab alone). Surgical resection will be performed 6 weeks after the first dose of neoadjuvant study intervention. Enrollment is planned for ~25 patients in combination and ~15 in the pembrolizumab monotherapy arms.Treatment will continue for up to 2 years (up to 1 year neoadjuvant/adjuvant therapy for substudy 02C), until disease progression, unacceptable toxicity, or study discontinuation. The primary end points include safety (adverse events and study intervention discontinuations) for all 3 substudies; objective response rate by blinded independent central review per Response Evaluation Criteria in Solid Tumors 1.1 for substudies 02A and 02B, and pathological complete response (pCR) as assessed by central review of the pathology results for substudy 02C. Secondary end points include duration of response for substudies 02A and 02B, and recurrence-free survival, near pCR, and pathological partial response rates for substudy 02C.

Due to the high parallelism and efficiency, Convolution acceleration and buffer pipeline architecture are common solutions for convolutional neural network (CNN) acceleration, however, existing accelerate solutions exhibit limited performance to accelerate CNN models. This paper presents a novel architecture as YOLO accelerate solution, which based on convolution loop unrolling and data flow pipeline optimization to reduce power consumption and maintain computational accuracy. The convolution loop unrolling algorithm is used to convert the numerous multiplication operations into addition operations to reduce the amount of computation. In the meanwhile, a buffer pipeline method which splits the processing element (PE) array is proposed, further improves the efficiency and optimizes the memory of the accelerator. Moreover, the data of the original model are processed at a low fixed point, reducing the resource consumption of the FPGA. Our proposed architecture can ensure the accuracy of network testing while reducing the power consumption required by the hardware.

Introduction: The head-up tilt table test is noninvasive diagnostic procedure, which is used in the diagnosis of syncope. Syncope presents a benign short-term disorder of cerebral circulation with the sudden loss of consciousness and muscle tone. Aim: The aim is to present not only the role and importance of orthostatic tests in the daily clinical practice of pediatric cardiology, neuropediatrics but also pediatrics in general. Patients and Methods: This study has retrospective descriptive character and included the period from April 1997 to June 2020, during which the registration and analysis of orthostatic stability tests (head-up/tilt table test, tilt table test) was performed. Medical documentation of outpatient and hospitalized patients on the Paediatric Clinic of Clinical Center University of Sarajevo (Register of Tilt Table Test) was used. Results: During this period, 1029 tests were registered and analyzed. Modification test (head-up) was performed in 132 (12.8%) patients, and since 2008, classic tilt table test was performed in 897 (87.1%) patients. Patients were 6.5–19 years old, with a predominance of female patients 611 (59.4%). There were 519 (50.4%) patients who were 15–19 years old and 510 (49.6%) patients who were under 15 years of age. Indications were syncope or suspected syncope in 671 (65.2%) patients, cardiovascular etiology (arrhythmias, chest pain, congenital heart defects [CHDs], surgically corrected CHDs, hypotension, and hypertension) in 195 (19%) patients, neuropediatric pathology (epilepsia, suspected epilepsia, headache, vertigo) in 101 (9.8%) patients, and other indications in 62 (6.03%) patients. From the total number of tests, 862 were first tests (83.4%) and 167 were control tests (16.3%). The positive test was found in 538 (52.3%) patients, most often vasovagal syncope (473 patients or 87.9%). Conclusion: Tilt table test is a reliable diagnostic tool in examining the etiology of syncope, primarily vasovagal, and is an extremely important method primarily in cardiopediatric and neuropediatric daily diagnostics.


Abstract Strategies that enable the efficient assembly of complex building blocks from feedstock chemicals are of paramount importance to synthetic chemistry. Building upon the pioneering work of Murai and co-workers in 1993, C–H-activation-based enantioselective hydroarylations of alkenes offer a particularly promising framework for the step- and atom-economical installation of benzylic stereocenters. This short review presents recent intermolecular enantioselective Murai-type alkene hydroarylation methodologies and the mechanisms by which they proceed. 1 Introduction 2 Enantioselective Hydroarylation Reactions of Strained Bicyclic Alkenes 3 Enantioselective Hydroarylation Reactions of Electron-Rich Acyclic Alkenes 4 Enantioselective Hydroarylation Reactions of Electron-Poor Acyclic Alkenes 5 Enantioselective Hydroarylation Reactions of Minimally Polarized Acyclic Alkenes 6 Conclusion and Outlook


Background: The investigational anti von Willebrand Factor (vWF) aptamer ARC1779 effectively inhibits vWF activity in blood samples of controls and of patients suffering from thrombotic thrombocytopenic purpura (TTP) (Jilma et al, Blood2007;110:279a, Gilbert et al. Circulation2007;116:2678–2686). Methods: A 39 year old comatose male patient with acute (TTP) was treated with daily plasma exchange. Further, the patient received rituximab (375mg/m2 first treatment on day 8, and weekly thereafter for 8 weeks) and was splenectomized on day 18. Due to the refractory nature of his TTP, the patient received a concomitant intravenous infusion of ARC1779 at a rate of 2 μg/kg/min beginning on day 30. Results: ARC1779 increased the platelet count slightly from 7 to a maximum of 30/nL; during this period septicaemia and DIC may have blunted the rise in platelet counts. However, platelet counts dropped to 5/nL by 16h after cessation of infusion (day 34). The infusion of ARC1779 was re-started on day 37, and platelet counts increased from 9 to 45/nL. (Figure) Due to a temporary lack of drug, the dose of ARC1779 was stopped at 78h, and platelet counts fell to 12/nL by 12 h after interruption of the infusion. (circle in the Figure) When ARC1779 was re-started, platelet counts increased to a maximum of 97/nL and the patient's neurologic status improved to near normal under therapy with ARC1779 over the next week. Conclusions: ARC1779 was well-tolerated, and caused a reproducible rise in platelet counts, which alleviated severe thrombocytopenia, in an otherwise refractory TTP case. This effect was reproducible under serial "re-challenge". Together with the observed improvement in neurologic function, the data provide clinical proof-of-concept and suggest that ARC1779 treatment might improve the organ dysfunction which typically occurs in acute TTP. These data provide a rational basis for ongoing and planned phase II trials of ARC1779.


ince the discovery of endothelial progenitor cells (EPCs) approximately 15 years ago,1 many scientists and clinicians have attempted to establish a successful procedure for cell-based therapy using EPCs in the field of cardiovascular medicine.2,3 Indeed, the use of EPCs for "therapeutic angiogenesis" was found to be effective for some patient populations, such as those with Buerger's disease. However, for patients with comorbid diseases (ie, diabetes mellitus or endstage renal disease (ESRD)), the efficacy of therapeutic angiogenesis4 is lower. The underlying molecular mechanisms of this inadequacy, as well as any interventional remedies, have yet to be clarified.


This chapter discusses the steps necessary to incorporate appropriate Scrum procedures into maintenance and enhancement projects on legacy systems, developed and maintained using a systems development life cycle (SDLC). It considers the benefits of introducing a more modular approach to system development, where the characteristics of existing systems have created interdependent modules, functions, and application architecture. Although these systems represent an investment in money, resources, time, and knowledge that make decommissioning them inexpedient, the process can and must be improved and incorporating Scrum procedures and practices will improve the success rate of maintenance and enhancements to these systems.


The upper airway resistance syndrome (UARS) is a sleep breathing disorder described by Guilleminault et al., in 1993, to identify patients that present increased respiratory effort and airflow limitation during sleep associated with an increase in the upper airway resistance. Patients usually complain of daytime sleepiness, fatigue, snoring, and difficulty to maintain sleep. Complains re lated to cognitive impairment, headache, anxiety, and irritability are also frequent. The physical examination shows nasal obstruction, increase in soft tissue and craniofacial abnormalities associated with decrease in the upper airway space. Nocturnal polysomnography does not show apneas or hyponeas for diagnostic criteria of obstructive sleep apnea syndrome (OSAS), and respiratory abnormalities consist on periods of increase in respiratory effort, sleep fragmentation, presence of respiratory event related arousal (RERAs) and presence of flattening of respiratory curve, which indicates airflow limitation. Controversies exist regarding the characterization of upper airway resistance syndrome as part of a continuum with other sleep breathing disorders, or as a separate entity that may not progress to obstructive sleep apnea syndrome. Treatment of upper airway resistance syndrome is more challenging than obstructive sleep apnea syndrome, since patients have lower tolerance for continuous positive airway pressure (CPAP) use. Other treatment modalities have been investigated, but they are still not established for clinical practice. Recognition of upper airway resistance syndrome is important, since it may prevent long-term consequences or progression to more severe forms of sleep-related breathing disorders.


Two methods for the prediction of the ionospheric parameters,the frequency domain characteristic parameters similar days,the time and frequency domain dual characteristic parameters similar days,are presented.A large quantity of data from nine ionospheric observation stations in China within a solar activity cycle(1977~1987) is used to test the validity of this method,and the result indicates that,compared with some available methods,the similar days method gives a more accurate result.The method developed here has the characteristic of simplicity and effectiveness,and is valuable for the application in real engineering.


This paper evaluates the performance of several control methods for small-scale variable speed wind turbines (WTs) in wind energy systems (WES). The methods that will be studied are maximum power point tracking (MPPT) control for below rated wind speed operation and yaw and stall control for above rated wind speed operation. In the paper, the simulation platform used for the study is described, yaw and stall control are explained, and simulation results are presented then discussed. The paper concludes with a comparison between yaw control and stall control performance.

The problem of aiming control, introduced in [1], is extended to systems with outputs. Necessary and sufficient conditions for output residence time controllability in linear SISO systems with small, additive noise are derived. Controller design techniques are developed and applied to aircraft and robotics control problems. The approach is based on an extension of the asymptotic first passage time theory to output processes.


mals. An extensive documentary annex and bibliography conclude the work. A network of international agreements imposes on cooperating states the requirement to remain within the "maximum sustainable yield" in harvesting a given species of fish. The interpretation and enforcement of this standard are, however, left to national authorities. Moreover, coastal states seek to extend their jurisdiction, and if allowed to do so, they would place 90 percent of commercially profitable species under national control. The enclosure of the oceans threatens the rights of all nations to the resources of the seas, and the author leaves little doubt as to the loopholes in modern international law. The internationalization of commonly held resources remains an elusive goal. The resolution of the Jan Mayen dispute (Norway/Iceland) in 1980 provides a useful point of comparison between the works by Tarija and Hey. Jan Mayen is a Norwegian possession 290 nautical miles from Iceland. Both states had overlapping claims in their exclusive fisheries zones, and a commission of conciliation convened to recommend a settlement. The outcome was a cooperative arrangement which Tanja describes as being based on equitable principles and leading to the formation of a regime based on cooperation. By comparison, Hey describes the settlement as one giving preference to Iceland. The difference between these two interpretations is attributable to the authors' varying points of reference. Tarija seeks to sustain the argument for equity and special circumstances in the delimitation of maritime boundaries, while Hey adopts a more formalistic approach of treaty interpretation. As noted above, the forum before which one is arguing a case makes all the difference. Tarija's thesis of special circumstances would find resonance before the u.s. Supreme Court, and Hey's textual analysis of treaty provisions would fit into the World Court's frame of reference. Read in tandem, these works can be of considerable value to the litigator.


An Internal Reforming Solid Oxide Fuel Cell (IRSOFC) is modeled thermodynamically; a Horizontal Axis Wind Turbine (HAWT) is designed; the combined IRSOFC-HAWT system should create a reliable source of electricity for the demand of a village located in Manjil, Iran. The output power of HAWT is unstable, but by controlling the fuel rate for the IRSOFC it is possible to have a stable power output from the combined system. When the electricity demand is over the peak or the wind speed is low/unstable/significantly high, the generated power may not be sufficient. To solve this problem, two scenarios are considered: connecting to the grid or using a Pumped Hydro Storage (PHS). For the second scenario, the extra produced electricity is saved when the production is more than demand and can be used when the extra power is needed. The economic analysis is done based on the economic conditions in Iran. The results will show a period of return about 9.5 and 13 years with the levelized cost of electricity about 0.0747 and 0.0882 $/kWh for the first and second scenarios, respectively. Furthermore, effects of some parameters such as the electricity price and the real interest rate are discussed.


Drinks packagings have undergone great changes over the past few years. For most of the drinks there has been a trend towards packagings that are turned into waste after being used a single time, as e. g. in the case of mineral waters, dairy products and, in future, also beer. The consequences of this development for waste management in Austria and possible remedial strategies are outlined in this article.


The purpose of this study is to continue an investigation of one of the chalcopyrite semiconductors (ZnSiAs/sub 2/) in order to assess its suitability as a solar cell material. ZnSiAs/sub 2/ was previously synthesized using an open tube vapor phase epitaxial growth technique, and epitaxial layers of ZnSiAs/sub 2/ were deposited on Ge and GaAs substrates (both (001) and (112) ZnSiAs/sub 2/ on (100) and (111) substrates, respectively). Epitaxial deposits were routinely achieved while the surface appearance varied from mirror-like to a dull appearance which resulted from a relatively rough surface topography. Mirror-like finishes were clearly an achievable goal but required additional refinements in growth technique and substrate preparation before they could be routinely achieved. Three critical goals have been identified that must be achieved before ZnSiAs/sub 2/ can be realistically assessed: (1) hole concentrations must be reduced from the current 10/sup 18/ to 10/sup 19//cm/sup 3/ range to the 10/sup 16/ to 10/sup 17//cm/sup 3/ range; (2) n-type ZnSiAs/sub 2/ must be demonstrated; and (3) ZnSiAs/sub 2/ p-n junctions must be demonstrated. The approach taken and the progress made toward achieving these goals as well as the planned effort for the next quarter are described.


Sustained monomorphic ventricular tachycardia (VT) in patients with heart disease is usually due to reentry involving a region of myocardial scar. Most commonly, the scar is due to prior myocardial infarction and associated with significantly depressed left ventricular function. Scars create a very stable substrate for VT, such that up to 70% of patients who present with sustained monomorphic VT late after myocardial infarction will have another episode within the next 2 years.1,2 Scars also occur in patients with nonischemic dilated cardiomyopathies (NICM) but are generally small, averaging less than 4% of the ventricular myocardium in one study using MRI.3 Replacement fibrosis is a likely mechanism. Consistent with the less frequent and smaller areas of confluent scar in nonischemic cardiomyopathies, sustained monomorphic VT is relatively infrequent. In patients with depressed left ventricular function who received an implantable cardioverter-defibrillator (ICD) for primary prevention, 15% had spontaneous VT or ventricular fibrillation detected by the ICD during a follow-up of 29 months, and approximately half of these arrhythmias were monomorphic VT.4

Article see p 494

Because large scars are not common in NICM, the possibility of bundle-branch reentry, which may occur without large scars, is an important consideration when sustained VT is encountered but accounts for fewer than 10% of VTs in this patient population.5 It has become increasingly clear that ventricular scars are a major factor causing sustained monomorphic VT in patients with NICM.6,7 Of patients who have recurrent episodes of VT, who are considered for catheter ablation, the vast majority have evidence of ventricular scars, based on voltage mapping or late Gd enhancement (LGE) on MRI.8 …


A pulsed fusion reactor potentially influences many commercial plant design provisions. Provisions related to turbine fatigue performance are among those considered important. They are evaluated by varying several design/operating parameters, separately and in combination, to present tradeoffs among them. These parameters include pulse length and capacity of the thermal storage system. A very simple and fast running temperature/stress representation of the turbine is used for evaluations. Results for wet-steam turbines indicate that requirements for thermal storage are quite large (steam flow between 40 and 80% of full steam flow). Modeling assumptions, design options, and important operating considerations are highlighted.


To meet the increasing need for reduction of exhaust emissions from stationary sources, many technologies have been developed to remove SO2 from flue gas. In this study the anodic oxidation of sulfur dioxide in aqueous solutions of sulfuric acid with a unique reactor design and electrode configuration has been investigated. An electrochemical absorption column larger than laboratory scale was employed. A titanium rod cathode and platinum expanded mesh anode separated by a cation exchange membrane were used as electrodes in the cylindrical electrochemical reactor. The effects of current densities of 10, 1, and 0.1 Am−2 , initial SO2 concentrations of 500, 2,500, and 5,000 ppm , gas flow rates of 0.75, 1.5, and 5 L min−1 , sulfuric acid concentrations of 1, 5, and 10%(w) , gas composition, and electrolysis time on removal efficiency, current efficiency, energy consumption, and mass transfer coefficient were reported. Removal efficiency of 94% was obtained with a high current efficiency of 94%, energy consum...


The goal of this research is to examine how the phenomenon social capital can be used to explain and describe the impact of situations on the lives of people during the time of the eruption of the Eyjafjallajokull volcano. The issue is explored through construction and analysis of a number of narratives representative of a farming community that has experienced two separate crises, i.e. the man-made economic crisis of 2008, and non-human natural crisis of the eruption of the Eyjafjallajökull volcano in 2010. The narrative is therefore to explain how the people who were relying on farming and other small business activities managed to survive during the eruption. Furthermore, 1 Elísabet I.

ArrayTracer is a high−level, low−overhead performance analysis tool for parallel applications. It provides the selective tracing facilities at a user−defined grain. The tracing technique used is program instrumentation. Instrumentation code is inserted at source code level during a source−to−source translation. The tool allows tracing of application's high−level concepts (e.g. program variables, subroutine calls, interprocess communication events, etc.) rather than tracing of low−level events (e.g. memory location accesses, disk accesses, network accesses, etc.). ArrayTracer is heavily based on compile− time information and attempts to off−load the execution time tracing overhead by extracting as much information as possible during the static analysis of application's source code. The tool's operations are divided into five stages: user interaction to determine trace parameters, instrumentation of source code during the compilation phase, collection of traces, processing of traces and analysis of the application's behavior, and presentation of the analysis results. In this report we focus on the first three stages, and present an encouraging preliminary performance evaluation.


Aim. To search early signs of cardiotoxicity in patients receiving anticancer therapy and evaluate the effectiveness of cardioprotection with an angiotensin-converting enzyme inhibitor, beta-blocker and myocardial cytoprotector.Material and methods. The study included 98 patients with high and very high risk of cardiotoxicity according to the Mayo Clinic scale (USA). Cancer patients with hypertension were offered cardioprotective treatment with a fixed-dose combination of perindopril and bisoprolol, and patients with very high risk and concomitant coronary artery disease additionally trimetazidine.The patients were divided into 2 following groups: the experimental group (n=50), where patients were prescribed cardioprotective therapy, and the control group (n=48), which consisted of patients who refused or had contraindications to cardioprotection. All patients underwent an examination, including the collection of complaints and anamnesis, physical examination, electrocardiography and echocardiography with an assessment of left ventricular (LV) global longitudinal strain before chemotherapy and 1, 3, 6, 9 and 12 months after initiation of anticancer therapy.Results. In patients of the control group, by the end of the follow-up, the left atrial volume index and LV end-diastolic volume index significantly increased. In the main group, these indicators did not change significantly. In the control group, by the final visit, the LV ejection fraction significantly decreased in comparison with the initial value and the value in the first group. After 6, 9 and 12 months, there was a significant decrease in the LV global longitudinal strain in the control group, while in the main group this indicator remained within the normal range. The mortality rate in the control group was significantly higher (15% vs 2% in the experimental group). In the experimental group, cardiotoxic complications occurred in 28%, while in the control group — in 78% of patients.Conclusion. The study demonstrated the significant importance of cardiac monitoring and primary drug prevention of cardiotoxicity of anticancer therapy. A sig nificant deterioration in LV systolic function was shown in patients with a high and very high risk of cardiotoxicity who did not receive cardioprotective therapy, while its high efficiency was demonstrated in patients of the experimental group.


This paper analyzes the determinants of CEO equity ownership in a sample of 273 young and innovative IPOs between 1997 and 2002. In contrast to other studies on managerial equity ownership, where managerial equity ownership is explained by agency-theoretic arguments, the empirical analysis in this paper is based on the property-rights approach. Arguing that asset ownership not only provides incentives for effort but also for specific investments, the empirical evidence in this study strongly confirms the property-rights approach. First, it could be shown that equity ownership significantly depends on intangible assets. Secondly, that contractual arrangements are more likely in the absent of such intangible assets and thirdly that complementary assets are more likely to be owned together and not separately.


Philosophers of language have lavished attention on names and other singular referring expressions. But they have focused primarily on what might be called lexical-semantic character of names and have largely ignored both what I call the lexical-syntactic character of names and also what I call the pragmatic significance of the naming relation. Partly as a consequence, explanatory burdens have mistakenly been heaped upon semantics that properly belong elsewhere. This essay takes some steps toward correcting these twin lacunae. When we properly distinguish that which belongs to the lexical-syntactic character of names, from that which belongs to the lexical semantic character of names, from that which rests on the pragmatics of the naming relation, we lay to rest many misbegotten claims about names and their presumed semantic behavior. For example, though many believe that Frege's puzzle about the possibility of informative identity statements motivates a move away from a referentialist semantics for names, I argue that the very possibility of Frege cases has its source not in facts about the lexical-semantic character of names but in facts about the lexical-syntax of the naming relation. If I am right, Frege cases as such are insufficient to justify the introduction of the distinction between sense and reference. In a similar vein, I offer a new diagnosis of the widely misdiagnosed felt invalidity of the substitution of co-referring names within propositional attitude contexts. That felt invalidity has been taken 2 to justify the conclusion that an embedded referring expression must be playing some semantic role either different from or additional to its customary semantic role of standing for its reference. I argue, to the contrary, that failures of substitutivity have their source not in the peculiar semantic behavior of embedded expressions but entirely in certain pragmatic principles. §1. On the Lexical-Syntax of the Naming Relation I begin by exploring the lexical-syntactic character of the linguistic category NAME. The contrast between the lexical-syntax and lexical-semantics is meant to distinguish lexically governed or constrained word-word relationships, on the one hand, from lexically governed and constrained word-world relationships, on the other. My central claim about the lexical-syntax of NAME is that names are a peculiar sort of anaphoric device. In particular, I claim that if N is a name, then any two tokens of N are guaranteed, in virtue of the principles of the language, to be co-referential. I will say that co-typical name tokens are explicitly …

Abstract:The increasing scholarly interest in the absence of fathers from family-focused interventions by the social services tends to focus on the role of fathers, mothers, and social workers in this absence. The role of policymakers, however, has been neglected. This article examines the case study of policymakers in the Israeli social services to fill in this gap and examine the role of policy and policymakers in fathers' absence. The findings reveal that policy is based on the 'mother-based intervention' assumption—the services are built around the assumption that interventions include only mothers, and therefore make engaging fathers an exception.


Ryerson University Library has been exploring different just-in-time acquisition models that provide us with cost-effective ways to purchase monograph titles with guaranteed usage. Based on our experience with Ebrary on the PDA (Patron Driven Acquisitions) Pilot, and with YBP on the DDA (Demand Driven Acquisitions) project, this discussion will focus on the theory behind our approach, the technicalities of implementation, and implications for future collection development strategies.


Communication aids with advanced microelectronics, voice synthesis, and artificial intelligence are under development. Some of these devices and their sophisticated human-machine interface strategies are described here.


In February 2008, a private physician in North Dakota radiographed hunter- harvested venison and found that 60 of 100 packages contained metal fragments. This discovery had implications for public-funded venison donation programs, and it prompted several Midwest states to examine their programs. Approximately 500,000 deer hunters harvest >200,000 deer annually in Minnesota, and the state has a donation program similar to North Dakota's program. Therefore, we analyzed fragmentation patterns and lead deposition in carcasses of 8 white-tailed deer (Odocoileus virginianus) and 72 domestic sheep (Ovis aries). We fired 5 different bullet types from centerfire rifles, and we also fired projectiles from both a shotgun and a black-powder muzzleloader. Centerfire bullets, which are designed to expand quickly upon impacting the animal, left bullet fragments and lead deposits throughout the entire abdominal cavity of carcasses. We also used 2 types of centerfire bullets that were purportedly designed to resist fragmentation. One of these bullet types had fragmentation patterns and lead deposition rates similar to the rapid-expanding bullets; the other bullet type resisted fragmentation, and no lead was detected in muscle tissue that we sampled. Centerfire bullets made from copper resisted fragmentation, and of course did not deposit any lead in muscle tissues. Projectiles fired from the shotgun and black-powder muzzleloader did deposit lead into carcasses but did not fragment as much as bullets fired from centerfire rifles. Our study suggests that rinsing the abdominal cavity may spread the lead contaminant to other areas of the carcass, thereby worsening the contamination situation. We suggest that hunters who use centerfire rifles and are concerned about lead exposure should purchase a bullet type that resists fragmentation.


The invention discloses a method for preparing high-purity basic cupric carbonate by an outer-coil internal-stirring type reaction kettle. The method comprises the following steps: taking pure copper, liquid ammonia and high-purity carbon dioxide as raw materials; firstly preparing strong ammonia water; introducing high-purity carbon dioxide into the strong ammonia water to prepare carbonated aqueous ammonia; reacting the carbonated aqueous ammonia with pure copper under a certain air pressure to obtain a copper-ammonia complex solution; and at last utilizing the outer-coil internal-stirring type reaction kettle to prepare the high-purity basic cupric carbonate. The method improves the reaction speed, shortens the production cycle, improves the product purity, greatly improves the production efficiency, lowers the production cost, significantly improves the quality and can be widely used for more products. At the same time, by adoption of the outer-coil internal-stirring type reaction kettle, the yield is high, the heat dissipation is low, the reaction time is short, the coal resource is saved, and the production cost is greatly reduced while the environmental protection requirement is better met.


This paper is addressed to the recommendation that the most effective strategy available to the poor for improving their condition is independent mobilization and the use of disruptive tactics. The most prominent exponents of this position are Frances Fox Piven and Richard Cloward. We examine their analysis of "poor people's movements" with particular emphasis on their account of the National Welfare Rights Organization and its failure. We conclude that (1) independent activities of poor people will fail to improve their status significantly and (2) for substantial improvement, it will be necessary to carry out activity within organized labor. We examine our rationale for this conclusion and the prospect for its success.


Fractures were the main seepage channels in low permeability conglomerate reservoirs.The study on the fracture growth rules directly influenced the development plan and the reservoir development effect.On the basis of qualitative geological description results,a dual-permeability and dual-porosity model was established.By adjusting the parameters of fracture and matrix,the distribution rules of permeability and its expanding direction in different areas of the fracture were studied.The result shows that the permeability of the fracture can be about 300 times as that of the matrix,the direction of the fracture is influenced by fault and it is changed near the fault at about 100m.The development plan is guided by the results and obvious effect is obtained.


According to extraordinary growth of network-based services, intrusion detection has been introduced as an important and efficient issue in the direction of network's security promotion. In order for coping with the infiltrators of networks and computerized systems, different methods have been codified which are called intrusion detection method the aim of which is that illegal usage and abuse and damaging the systems and computerized networks is recognized by both internal users and external attackers. Generally, intrusion detection methods are divided in to two main categories of abuse detection and abnormal behavior detection. In abuse detection method, known intrusion patterns are used for recognizing the intrusions but in abnormal behavior detection methods, normal behavior of the users has the main criterion. As a result, any inconsistent behavior with that is considered as an effort for permeating the system. In this paper, intrusion detection systems and their performance are considered and finally we will become familiar with intrusion detection methods including data mining algorithms.


An engineered lightweight architecture has been used on the server side for different purposes. One of them was to provide an environment for data collection and analysis. Since most of the data analysis is static- and post-process, there is a challenge to apply existing data analysis to data collected in real time. In this paper, we propose an architecture that uses the multiscale entropy analysis (MSE) method to analyze data. This system was used to analyze real electrocardiogram (ECG) data in pseudo real-time. The architecture is divided into three parts: (1) a lightweight back-end system that includes Node.js, MongoDB, Nginx, (2) the use of physiological data from PhysioNet to simulate a real-time environment, and (3) the use of MSE to analyze the simulated data. The current findings are beneficial to the community of health science since it removes the necessity of setting up a real-time environment in order to run the tests on new algorithms and methods.


To mitigate the online computational load of model predictive control, move blocking, which parameterises either the input sequence or offset from the base sequence by fixing the decision variables over arbitrary time intervals, is commonly used. However, existing move blocking schemes use a fixed base sequence only and do not fully exploit the valuable properties from various base sequences. Thus, we propose the interpolated solution-based move blocking strategy which parameterises the offset from the convex combination of two complementary base sequences – infinite-horizon linear quadratic regulator solution and shifted previous solution – and optimises the interpolation parameter as an additional decision variable in the optimal control problem. This allows the controller to exploit the valuable properties from both solutions by choosing the optimal interpolation parameter and blocked offset according to the current state online. The proposed approach efficiently improves the optimality performance whileguaranteeing the recursive feasibility and closed-loop stability.

A novel counter architecture, called Counter braids, has recently been proposed for per-flow counting on high-speed links. Counter braids has a layered structure and compresses the flow sizes as it counts. It has been shown that with a maximum likelihood (ML) decoding algorithm, the number of bits needed to store the size of a flow matches the entropy lower bound. As ML decoding is too complex to implement, an efficient message passing decoding algorithm has been proposed for practical purposes. The layers of Counter Braids are decoded sequentially, from the most significant to the least significant bits. In each layer, the message passing decoder solves a sparse signal recovery problem. In this paper we analyze the threshold dimensionality reduction rate (d-rate) of the message passing algorithm, and prove that it is correctly predicted by density evolution. Given a signal in R+ n with ne non-vanishing entries, we prove that one layer of Counter Braids can reduce its dimensionality by a factor 2.08 epsi log(1/epsi) + O(epsi). This essentially matches the rate for sparse signal recovery via L1 minimization, while keeping the overall complexity linear in n.

This study examined the Nigerian financial sector and adjusted net savings in Nigeria. Time series data from 1986-2015 were obtained from the World Development Indicators, Central Bank of Nigeria Statistical Bulletin and the annual reports of National Insurance Commission. An Autoregressive Distributed Lag (ARDL) bound test was estimated and findings reveal that: The banking sub-sector has a positive and significant relationship ( ) with adjusted net savings in Nigeria; the Stock market sub-sector positively and significantly ( ) affects adjusted net savings in Nigeria; and the insurance sub-sector has no significant influence ( ) on adjusted net savings in Nigeria. This study concluded that the banking and the stock market sub-sectors of the financial system significantly influence adjusted net savings in Nigeria. Study therefore, recommends that the government through its regulatory authorities should pay more attention to the banking and stock market sub-sectors of the financial system in order to make them resilient, effective and efficient towards channelling funds to productive or growth driven sectors, to significantly impact on adjusted net savings in Nigeria thereby propelling sustainable development in Nigeria.


Library and information management (LIM) organisations are on an almost continual path of change influenced by developments in technology, service models, financial allocations and staffing structures. The way in which LIM organisations approach change varies as does the success rate of the change management procedures initiated. Appreciative Inquiry (AI) is an approach to change management that has been gaining in popularity with organisational development (OD) practitioners since its inception over three decades ago. AI seeks to identify what works with individuals, teams or whole organisations and then build on those elements. This is a digression from the common change management approach of looking for a problem that needs to be fixed. To date, there has been only minimal evidence of LIM organisations utilising AI as a positive change management technique. This research discusses the issue of change management in LIM organisations and explores the applicability of the AI technique for LIM organisations particularly those operating with virtual teams. This project for the Doctor of Information Management has two stages. The first stage was the application of the Discovery phase of the AI cycle applied as part of change management workshops involving the CSIRO Information Management & Technology (IM&T) Library and Records staff in February 2007. Building on this foundation work, the second stage was the application of the full AI 4-D model in the development of a Professional Development strategy for the CSIRO IM&T Library Services team as a means of enabling staff to be agile with regards to their professional skills in an ever-changing work environment. The outcomes of these applications of AI are presented here along with recommendations for further research and implications for LIM organisations utilizing AI as a positive change management technique.

The first chromatic hard X-ray interferometer with a large and variable path length difference has been built and successfully tested. Interference fringe visibility was measured as a function of the path length difference. Based on the measurements, fringe visibility analysis was performed to give the transmitted beam coherence lengths. The results agree very well with expected coherence values based on the angular and spectral acceptances of the interferometer.

www.expert-reviews.com ISSN 1743-4440 © 2012 Expert Reviews Ltd 10.1586/ERD.12.48 Conventional cell-culture systems used in biology do not accurately reproduce the structure, function or physiology of living tissue [1]. As a result, there are substantial discrepancies in behavior and responses of cells compared with in vivo environments. For example, Bokhari et al. have shown that HepG2 hepatocytes grown on 3D polystyrene scaffolds are less susceptible to certain toxicological challenges [2]. Their work suggested that testing drugs on liver cells should be performed in a 3D cell culture, since observed responses are more similar to that of natural tissue. Stegemann et al. have shown that the response of vascular smooth muscle cells (VSMCs) to the biochemical and mechanical signals differs depending on the extracellular environment [3]. The evaluation of interplay between different biomimetic factors is particularly challenging. For example, MJ Bissel's group has shown that both appropriate matrix elasticity and presence of laminin are required in order for mammary epithelial cells to maintain their differentiated phenotype [4]. Similarly, Peyton et al. revealed a synergetic effect of matrix elasticity and RhoA activation on the VSMC phenotype [5]. Numerous other examples can be found in related reviews on this topic [6–8]. Until recently, cell-culture matrices were mainly considered from a standpoint of support and guidance of cell proliferation and tissue development. The early designs of tissue engineering constructs focused on bulk properties, while disregarding the individual cell environment. A number of approaches for the realization of porous matrices, in the form of hydrogels or scaffolds, have been developed in recent years; with a different degree of success they all aim at approximating the complexity of the natural cell environment. However, the majority of current methods for realization of 3D cell-culture matrices allow the study of only particular biomimetic aspects of a natural extracellular matrix (ECM) without the possibility to evaluate the interplay of different effects. The main reason for this is that, owing to the technical limitations of these Aleksandr Ovsianikov*1, Vladimir Mironov2, Jürgen Stampfl1 and Robert Liska1

This paper presents a power electronic circuit used to extract usable electrical power from a backpack-based energy harvesting system. The rectified output of a generator is connected to a SEPIC converter which emulates a resistive load, resulting in efficient energy conversion. The harvested energy is stored in ultracapacitors, where it is then used to charge electrochemical batteries and/or power an electronic load. A switchable resistive load is engaged to dissipate any excess electrical power that cannot be used or stored. As shown in experimental results presented in this paper, 16W of usable electric power is harvested under conditions representative of human walking.


Software-in-the-Loop (SiL) is a test strategic sweet spot between Model-in-the-Loop (MiL) and Hardware-in-theLoop (HiL) tests.

In the Missouri Ozarks, 6 and 8 years after treatment, understory biomass differences between bole only harvesting (BO) and whole-tree plus forest floor harvesting were not different; neither were there understory biomass differences between no compaction and severe compaction. Separation of the biomass into broad species categories (trees, shrubs, annuals, perennials, grasses, woody vines, and annual vines) showed some categories to be different between treatments. Some differences in species abundance over time were also noteworthy. Understory vegetation is important to the survival and growth of the developing stand and has significant implications for wildlife populations, fuel loads, and nutrient cycling, all of which can be considered part of site productivity.
