Children with learning and behavior problems may have mild growth suppression when created with stimulant medication for poor attention or hyperactivity. However, data is unavailable substantiating normal growth in untreated children. This study was undertaken to identify any difference in growth parameters of such children compared to national norms. A retrospective analysis was undertaken via chart review of 97 boys between 6 and 11 years of age, with normal intelligence and on no medication, evaluated for learning or behavior problems and diagnosed as learning disabled, attention deficit disorder, and/or minimal cerebral dysfunction. Height and weight were obtained at initial evaluation with a standard medical scale. A z-score was assigned for these values as well as weight-for-height ratio (w/h) based upon the Natl. Ctr. for Health Statistics standards. Analysis of SES, number of behavior problems, IQ, reading quotient, and parental education was performed to identify any correlations with these measures. Height, weight, and w/h showed no statistically significant difference between this group and the general population (mean z-score ± 1 SD: 0.06 ± 1.23, 0.18 ± 1.22, 0.18 ± 1.02, respectively). No correlations were found between these growth measures and the other factors. We conclude that children with learning and behavior problems, including subclasses of these children, are of normal stature and weight.


The transverse induced vibrations of propeller shaft are studied. The stern section of a propeller shaft is modeled with a beam, resting upon nondeformable supports. An inertial force of a screw is taken into account. The resulting solution allows us to investigate both the factual frequency of the propeller shaft and the displacement of the sections of the shaft in the process of oscillations. The solution has an independent significance because it describes the process of double-bearing beam oscillation with a console supporting a concentrated mass at its free end.

The dip coating procedure led to accumulation of coating particles at the coating solution and substrate interface. After sintered, frit dissolution implied an occurrence of liquid phase sintering. Simultaneous improvement of surface morphology and bulk density was evident. The significant appearance of cracks and roughed surface of plain porcelain was revolved into crack free and smoother exterior following the dip-coating and sintering process. The surface was properly glazed. This led to enhanced body densification, and sealing of apparent micropores. At the same time, the deposited coating reduced the amounts of open cells and surface defects, which caused reduction in porosity and increment of bulk density.

Abstract : Headquarters, U.S. Army Health Services Command (HQ HSC) requested the Group Health Association of America (GHAA) Consumer Satisfaction Survey instrument be used to survey potential users of DoD medical treatment facilities (HSC Task Number 2293). A similar survey was administered in 1989 and it was recommended that patient satisfaction surveys be conducted each year. The GHAA instrument was adapted for a military population and sent out from November 1990 through April 1991. Returned instruments were edited and comments coded. Items were scored as suggested by GHAA and were developed using the GHAA criteria. The 10 GHAA content categories were access, finances, technical quality, communication, choice and continuity of providers, interpersonal care, outcomes, overall quality, time spent, and general satisfaction....

The article designates a new stage in the evolution of Facebook* as a global communication platform that aggregates data on its users for different purpose. Studying a real case, it shows that at present, social networks are a place for transforming everyday communication into strategic one while making this process not obvious to the social network users themselves. The research methodology consists of the Web 2.0 concept by T. O'Reilly, the theory of weak ties by M. Granovetter, and the concept of memes by R. Dawkins. Based on the analysis of media publications and preceding studies, as well as on the example of a recent case in Facebook* and VKontakte networks, the author actualizes the space of social networks as a space of strategic communication, and comes to the conclusion that it is necessary to educate users about the nature and true goals of such communication and wars carried out in the space of social networks in a permanent mode.


A tradition of work in cognitive science indicates that much of our mental lives is not available to introspection (e.g. Nisbett and Wilson, 1977; Gopnik, 1993; Wegner, 2002). Though the researchers often present these results as surprising, little has been done to explore the degree to which people presume introspective access to their mental events. In this paper, we distinguish two dimensions of introspective access: (i) the power of access, i.e. whether people believe they can unfailingly or only typically introspect mental events; and (ii) the domain of access, i.e. what types of mental events people believe they are able to introspect. We report four experiments carried out to discover where lay beliefs about introspection fall on these dimensions. In our experiments, people did not presume universal introspective access, but they did overestimate the amount of access they actually have, particularly in the case of decisions.


Background: APC is modified with Lys-63-linked polyubiquitin when bound to Axin in an assembled β-catenin destruction complex. Results: HectD1 E3 ligase modifies APC with Lys-63-linked ubiquitin chains to facilitate the APC-Axin interaction. Conclusion: HectD1 is a candidate E3 ligase for APC. Significance: The identification of HectD1 could lead to a better understanding of APC function. The adenomatous polyposis coli (APC) protein functions as a negative regulator of the Wnt signaling pathway. In this capacity, APC forms a "destruction complex" with Axin, CK1α, and GSK3β to foster phosphorylation of the Wnt effector β-catenin earmarking it for Lys-48-linked polyubiquitylation and proteasomal degradation. APC is conjugated with Lys-63-linked ubiquitin chains when it is bound to Axin, but it is unclear whether this modification promotes the APC-Axin interaction or confers upon APC an alternative function in the destruction complex. Here we identify HectD1 as a candidate E3 ubiquitin ligase that modifies APC with Lys-63 polyubiquitin. Knockdown of HectD1 diminished APC ubiquitylation, disrupted the APC-Axin interaction, and augmented Wnt3a-induced β-catenin stabilization and signaling. These results indicate that HectD1 promotes the APC-Axin interaction to negatively regulate Wnt signaling.


New technologies and innovations can significantly contribute to removing or reducing problems related to modern transport. Hyperloop is an innovative mode of transport whose task is to move people or loads at very high speed, based on the concept of sustainable transport. Due to the benefits it brings - environmentally friendly, fast, self-sufficient in terms of energy, ensuring a high level of mobility, is an interesting option that in the future can replace the existing means of transport. The aim of this article is to present the theoretical and empirical aspect of the innovative mode of transport - Hyperloop, as an attractive alternative, which in the future can replace the existing branches of transport. The work consists of a theoretical and empirical part. The theoretical part of the work presents selected contemporary transport problems, the concept of innovations in transport and the mode of transport - Hyperloop. The empirical part of the work presents a proposal to connect selected European cities and estimate the time of traveling between them using Hyperloop.


We report on our investigations of the structural and electronic properties of n-conductive organic field-effect transistors (OFETs). For this purpose we employed the atomic force microscopy (AFM) and Kelvin-probe force microscopy (KPFM) in dual frequency mode. This study facilitates the determination of the local potential in the channel of active OFETs. We studied the influence of insulator treatment on the electrical potential and field distribution within the channel using a self-assembled monolayer of N-octadecyltrichlorosilane (OTS). For the investigated OFETs we used air-stable and electron conducting N,N′-bis(n-octyl)-dicyanoperylene-3,4:9,10-bis(dicarboximide) (PDI-8CN2). It appears that the insulator treatment improves the performance even if the surface topography did not change. These results can lead to a better understanding of the charge transport and injection and pave the way towards the optimisation of the electronical properties of active organic devices (© 2010 WILEY-VCH Verlag GmbH & Co.

In this paper, we propose a generic design approach for efficiently reducing data samples. The significant design spirit is to apply and check the correlation relationship between each feature and the classified label. It is applicable for any types of machine-learning models, providing 5-tuple parameters. By adjusting the design parameters, our systematic approach can achieve the trade-off between classification accuracy and sample reduction ratio while satisfying the users' demand. In the verification with suggested parameter setting and different ML models, the data samples are reduced by 15%–25% under the acceptable accuracy loss.


The distribution of false stable fly, Muscina stabulans (Harris) (Diptera: Muscidae) is worldwide. Control of M. stabulans has been seldom done; therefore, this study investigated some biological aspects post treatment of four essential oils through ingestion and contact bioassays against the 3 rd larval instars of M. stabulans . Post treatment (PT) with 50%, the mortality% of larvae, pupae, both larvae and pupae, and adults reached 83.33, 73.33, 95.56, and 100%, respectively, for Apium graveolens (celery); 73.33, 75.00, 93.33, and 100.00%, respectively, for Eruca sativa (ruca); 80.00, 100.00, 100.00, and 100.00%, respectively, for Lactuca sativa (lettuce); and 63.33, 81.82, 93.33, and 90.00%, respectively, for Raphanus sativus (radish) . The pupation and adult emergence rates PT with 50%, and LC 50 values were 4.44, 0.00, and 21.743%; 6.67, 0.00, and 24.786%; 0.00, 0.00, and 20.909%; and 6.67, 10.00, and 31.826%, respectively. On the other hand, their toxicity indices reached 96, 84, 100, and 66%, respectively. This study indicated that L. sativa was the most effective oil, followed by A . graveolens and E. sativa; whereas R. sativus was the least effective oil . To conclude, essential oils could be used as ecofriendly fly management in organic farming and in places where conventional insecticides could not be applied.


OBJECTIVE
To find the view of family and community medicine (FCM) residents on the kinds of relationship between tutors and residents and their training.

DESIGN
The methodology employed was qualitative; and the technique chosen, that of focus groups.

SETTING AND PARTICIPANTS
FCM residents belonging to the teaching units in Murcia and Cartagena.

INTERVENTION
Five groups were organised, two second-year resident groups, two third-year ones, and one first-year one. At the start of each group the objectives and norms of the meeting were explained. Residents were then asked four questions about their relationship with their tutor and the training received during their residency. The information arising was classified as a function of the time of debate, the number of residents expressing the same view and the intensity of their emotional involvement on expressing their views.

RESULTS
The tutor's confidence in the resident's work was what residents valued most highly, along with the exchange of views as equals. The participants stated that they wanted to take part in planning their training and that they needed to participate in the clinical and organisational decisions taken in the tutor's clinic.

CONCLUSIONS
Trust between tutor and resident is essential. Communication between the two must be on an equal basis. Training procedures are valued higher than training content. Residents want to intervene in planning their training. Tutors are models for training.


The design of new steel‐timber composite beam, called Nordic system, is proposed. The beam consists of CLT (Cross Laminated Timber) slabs that are installed on the bottom flanges of an asymmetric welded steel box. The composite action is achieved through connection the slabs to the steel beam by steel plates which are screwed to the timber and bolted to the top flange of the beam. The composite action reduces the stresses of the steel beam compared to the pure steel beam without composite action. This means that there exists a large potential to search lightweight, dry slim floor, low emission and cost optimal solutions using this composite beam due to large variations for available steel grades of the welded beam, as has been shown previously for pure welded steel beams.


The experimental differential cross-sections for the 6Li elastic scattering by 28Si over the incident energies ELi=7.5–99.0 MeV and vector analyzing power data at 22.8 MeV have been analyzed in terms of a non-monotonic potential, microscopically derived from the energy-density functional (EDF) theory using a realistic two-nucleon potential that incorporates effects of the Pauli principle. The data are accounted for well without any need for renormalization of the potential or adjustment of its parameters. Inclusion of a static spin-orbit potential with the EDF-generated central real one is found to describe satisfactorily the features of the vector analyzing power data.


We propose a preemptive priority handoff scheme for integrated voice/data cellular mobile systems. In our scheme, calls are divided into three different classes: handoff voice calls, originating voice calls, and data calls. In each cell of the system there is a queue only for data calls. The right to preempt the service of data is given to a handoff voice call if on arrival it finds no idle channels. The results are compared with another handoff scheme. It is shown that, when the data traffic is not very light, our scheme can provide better quality of service (QOS) to mobile users.

With a formal model of the service portfolio to better ensure the combination of accuracy, and other related characteristics.


Congestive heart failure (CHF) is a cardiac disease associated with the decreases in cardiac output. As a measure to predict sudden death, we propose a framework for discriminating CHF subjects from normal sinus rhythm (NSR). This framework relies on matching pursuit decomposition to derive a set of features, which are tested in a hybrid genetic algorithm and k-nearest neighbor classifier to select the best feature subset. The performance of the proposed framework is analyzed using both Fantasia and CHF database from Physionet archives which are, respectively, composed of 40 NSR volunteers and 29 CHF subjects. The proposed methodology reaches an overall accuracy of 100% when the features are normalized and the feature subset selection strategy is applied. We believe that our method can be extremely useful to the clinician in primary health care as a support tool to discriminate healthy from CHF subjects.


This note suggests that, contrary to the conclusions reached in several recent studies, the empirical evidence does not support the view that financial development promotes economic growth. It is first noted that the predominant pattern in the data for 95 individual countries is that of a negligible or weakly negative covariation between financial development and growth of real GDP per capita. Second, the individual‐country correlational picture is a sharp contrast to the correlations based on crosscountry data that have been used in most research on the subject. Third, individual‐country estimates of a basic multiple‐regression growth model also do not indicate a positive association between financial development and growth. Fourth, in cross‐country data and models of the kind that have been used in most studies, when the regression structure is permitted to vary across three subgroups, a huge parametric heterogeneity is observed, and the overall indication is that of a negligible or negative association...


The discovery and identification of a new drugs, which can act as anticancer agents had an important goal of researches. This study demonstrates the favorable effects of Iraqi wild type Lycium barbarum active components as anticancer agent. Flavonoids from Lycium barbarum leaves were extracted and identified by the preparative thin layer chromatography (PTLC) technique which was the best to separate several flavonoids among them; Rutin, Quercetin, Kaempferol, luteolin and a major quantity of unknown flavonoid that had been separated and purified to evaluate its biological activity. Results showed that Iraqi L. barbarum leaves contain total flavonoids (11.28 mg/g dried leaves) calculated as Quercetin, and the purified extracted flavonoid showed cytotoxic effect towards both: the primary cell culture of normal hepatic cells (WRL-68), and cancer hepatic cell lines (HepG-2) at 100μg/ml concentration for 24 hours treatment. The High Content Screening (HCS) assay was held only for the purified flavonoid to investigate the mechanism by which the purified flavonoid affected living cells toward apoptosis. The most significant reduction (p≤0.05) in cell viable count was at the concentration 100μg/ml which appear to cause the induction of cell death via mitochondrial pathway for HepG-2 cell line after 24 hours exposure.


Objective: This article aims to discuss the role of nutrition therapy in Inflammatory Bowel Diseases according to its indications, contraindications, and the as main results obtained with prebiotics, probiotics, symbiotics and other nutritional interventions. Data source: We performed a literature review using the databases Pubmed, Scielo and Lilacs. Data synthesis: Inflammatory Bowel Diseases are chronic illnesses that affect primarily the gastrointestinal tract and are divided in two most common forms of presentation: Crohn's Disease and Ulcerative Colitis. The chronic inflammation can cause intestinal lesions, anorexia, nutrients malabsorption, oxidative stress and higher energy consumption, increasing the risk of malnutrition. Nutritional status is directly associated with the disease severity and malnutrition is a serious complication of inflammatory bowel diseases that worsens the patients' prognosis. Nutritional therapy is used to prevent or treat the malnutrition, to correct macro and micronutrients deficits and to reverse some of the metabolic and pathological consequences of these diseases. In the majority of patients, the nutrition therapy has an adjuvant role combined to medical or surgical treatments, but in some specific situations it can be the main treatment. Conclusions: Despite the benefits of nutritional therapy, more meta-analysis and double-blind controlled studies about these diseases are required to assure the good results obtained in some of the published trials

Effects of fermentation variables on conjugated linoleic acids (CLAs) biosynthesis of Lactobacillus fermentum DDHI27 in modified skim milk were evaluated. A total of 0.5 mg/mL was found to be the optimum linoleic acid concentration for maximum CLA production and this level was used in utilised for all successive experiments. The highest production of CLA isomers was detected at pH 6.0 when compared to other pH levels. Maximum biosynthesis of CLA isomers occurred during stationary growth (48 h) phase at all pH values tested. Validation of CLA isomers produced in selected samples was made by GC-MS. These results indicate that these parameters strongly influence the CLA production capabilities of the strain.


Significance Nucleophosmin (NPM1) is a multifunctional protein with critical roles in ribosome biogenesis, centrosome duplication, and tumor suppression. Despite the established importance of NPM1 as a tumor marker and potential drug target, little is currently known about the molecular mechanisms that govern its various functions. Our manuscript describes that the N-terminal domain of NPM1 (Npm-N) exhibits phosphorylation-dependent structural polymorphism along a broad conformational landscape between two extreme states: a stable, folded pentamer and a globally disordered monomer. We propose that phosphorylation-induced "regulated unfolding" of Npm-N provides a means to modulate NPM1 function and subcellular localization. Our findings will drive future structure-based studies on the roles of regulated unfolding in NPM1 biology and will provide a foundation for NPM1-targeted anticancer drug development. Nucleophosmin (NPM1) is a multifunctional phospho-protein with critical roles in ribosome biogenesis, tumor suppression, and nucleolar stress response. Here we show that the N-terminal oligomerization domain of NPM1 (Npm-N) exhibits structural polymorphism by populating conformational states ranging from a highly ordered, folded pentamer to a highly disordered monomer. The monomer–pentamer equilibrium is modulated by posttranslational modification and protein binding. Phosphorylation drives the equilibrium in favor of monomeric forms, and this effect can be reversed by Npm-N binding to its interaction partners. We have identified a short, arginine-rich linear motif in NPM1 binding partners that mediates Npm-N oligomerization. We propose that the diverse functional repertoire associated with NPM1 is controlled through a regulated unfolding mechanism signaled through posttranslational modifications and intermolecular interactions.

Under similar conditions, selenated heterocycles are also synthesized.


A novel miniaturized and high‐isolated multiple‐input multiple‐out (MIMO) antenna is proposed. It is very difficult to reduce the mutual coupling between the MIMO antenna elements for compact mobile handset. Three‐dimensional meander lines are used as the radiator, which miniaturizes the size of the antenna. Decoupling network is introduced to improve the isolation between the ports of the two monopoles effectively. Concavo–convex rectangle is used as its ground which improves the voltage standing wave ratio (VSWR) instead of the match circuits. The proposed antenna works at 2.4 GHz. Antenna prototype is fabricated and tested, which proves its performance. In the working band, the reflection coefficient of the proposed antenna is below −10 dB, and the isolation below −15 dB. The proposed antenna has patterns close to be omnidirectional. It can be used in various areas such as MIMO, Wi‐Fi, and Bluetooth. © 2011 Wiley Periodicals, Inc.

In an open economy,the development of two-way FDI is determined by the economic development of a country. Proper inward and outward FDI can promote the economic growth and development of a country through different mechanisms or channels. The result of an empirical study on the correlation between two-way FDI and China's economic development from 1982 to 2012 shows that during 1982 to 2009 in China,the relationship between two-way FDI and per capita GDP is in accordance with the J curve hypothesis of Dunning's IDP theory,and it began to enter the third stage of Dunning from 2007. But in 2010 and 2011,the relationship deviates from the curve. There is a long-term stable equilibrium relationship between two-way FDI and per capita GDP in China,and the growth effect of OFDI is stronger than that of IFDI. However,in the short run,only one-way Granger causality from IFDI to per capita GDP can be found between per capita GDP and IFDI,and there is no Granger causality between per capita GDP and OFDI.


This special article is based on the contents of a lecture given by Sampaio and was written together with Bagatin. It is a summary of the authors' experience treating various forms of acne before and after the introduction of oral isotretinoin, which revolutionized the management of the disease. Nowadays, this drug is considered the unique option to obtain a prolonged remission or cure of acne due to its action in all etiopathogenic factors involved in the disease. Therefore it should be prescribed in accordance to current recommendations, as well as for difficult cases, including those showing tendency to scars or serious psychological and social repercussions. Other topical and/or systemic therapeutic modalities should be considered in the initial approach and for mild and moderate cases.

A particularly successful role for Inductive Logic Programming (ILP) is as a tool for discovering useful relational features for subsequent use in a predictive model. Conceptually, the case for using ILP to construct relational features rests on treating these features as functions, the automated discovery of which necessarily requires some form of first-order learning. Practically, there are now several reports in the literature that suggest that augmenting any existing features with ILP-discovered relational features can substantially improve the predictive power of a model. While the approach is straightforward enough, much still needs to be done to scale it up to explore more fully the space of possible features that can be constructed by an ILP system. This is in principle, infinite and in practice, extremely large. Applications have been confined to heuristic or random selections from this space. In this paper, we address this computational difficulty by allowing features to be constructed in a distributed manner. That is, there is a network of computational units, each of which employs an ILP engine to construct some small number of features and then builds a (local) model. We then employ a consensus-based algorithm, in which neighboring nodes share information to update local models. For a category of models (those with convex loss functions), it can be shown that the algorithm will result in all nodes converging to a consensus model. In practice, it may be slow to achieve this convergence. Nevertheless, our results on synthetic and real datasets that suggests that in relatively short time the "best" node in the network reaches a model whose predictive accuracy is comparable to that obtained using more computational effort in a non-distributed setting (the best node is identified as the one whose weights converge first).


A reliable communication link between two destinations in a microwave environment requires a propagation path clear of interference signals. An effective method of interference suppression is to form nulls in the antenna pattern in the directions of the interference. Steyskal (1983) proposed null steering in the antenna pattern by using the small phase perturbation. This paper extends the spatial phase perturbation methods used for null steering in a linear array to include a circular array. In this technique the array utilizes the phases obtained from perturbing the radial locations of a circular array to suppress the interference signals. This technique is applied to a Chebyshev-like circular array with 36 elements.


Amphibian migrations are mainly associated with seasonal movements between terrestrial and aquatic (breeding) habitats, but inter-pond migrations during the breeding season present a rarely observed and understudied phenomenon. In 2018 and 2019, a total of 501 individual newts (168 females and 333 males) from two ponds were captured using funnel traps, the ventral side of each newt was photographed and recaptures were identified using the image recognition software Hotspotter ver. 1.0. The distance between ponds was 200 m, with a slight downward slope from pond 1 to pond 2 and terrestrial vegetation consisting of shrubs, grassy patches and trees. All recorded inter-pond migrations were males (three and two individuals in 2018 and 2019, respectively). Between years, ten males were recorded to move between ponds, three of which were identical to individuals that also migrated between ponds within a single season. The observed behavior is discussed in terms of rarity, distance and time of migration.


The praise to the RenXia spirit of the poets of the prosperous Tang was the highest.it was only a superficial phynomenon that the poets spoke highly of Renxia spirit.Their purpose was to express their warm feelings-loving life,being useful,serving society,being successful and wishing to be adimited about their value.So the essence of the RenXia spirit of the prosperous Tang poetry was a active spirit that was a similar with the Ru's thoughts.


This paper presents a design and simulation of digital PLL synchronizer, using Costas loop based on SDR for high frequency communication systems. Design parameters are selected for each unit of the proposed systems in order to accommodate SDR requirements. Different techniques for carrier recovery based on SDR are discussed. PLL techniques is chosen for synchronization, since it is one of the most active synchronization techniques. BPSK and QPSK synchronizers for coherent receivers have been designed and simulated based on SDR using both Costas loop and modified Costas loop. The simulation result shows that these two systems are reliable in recovering the carrier phase and frequency when significant frequency and phase are present. Simulation result shows that the BPSK system has e P = 3 10 - at o b N E / equal to 8.5 dB in the presence of AWGN and has the ability to track frequency offset up to 1200Hz with 2*10 4 - probability of bit error at o b N


The web is loaded with textual content, and Natural Language Processing is a standout amongst the most vital fields in Machine Learning. But when data is huge simple Machine Learning algorithms are not able to handle it and that is when Deep Learning comes into play which based on Neural Networks. However since neural networks cannot process raw text, we have to change over them through some diverse strategies of word embedding. This paper demonstrates those distinctive word embedding strategies implemented on an Amazon Review Dataset, which has two sentiments to be classified: Happy and Unhappy based on numerous customer reviews. Moreover we demonstrate the distinction in accuracy with a discourse about which word embedding to apply when.


This paper proposes a novel non-isolated high step-up converter suitable for miniaturization by high frequency design. High step-up converters with voltage multipliers are promising for high frequency design because many of them can be free from coupled inductors or transformers, which may lower the voltage gain due to the leakage inductance or may cause significant AC conduction loss in the primary winding. However, two issues can still hinder further miniaturization. One is that many multiplier stages may be needed to achieve extremely high voltage gain. The other is that high switching frequency may be restricted by severe turn-off voltage surge caused by high speed switching. The proposed converter addresses the former by applying a recently reported technique to a non-isolated boost converter. Additionally, the converter addresses the latter by proposing a simple passive regenerative turn-off snubber implementable only by two diodes and a capacitor. Experiments verified that the proposed converter achieves high voltage gain with fewer voltage multiplier stages compared to prior non-isolated high step-up converters. Additionally, the snubber successfully reduced the turn-off surge into half approximately without apparent deterioration of the efficiency.


This paper introduces the mainstream secure multi-party computing technology in the blockchain, which provides a reference for further research in the blockchain field. First, we analyze the privacy protection issues in the blockchain and conclude that secure multi-party computing can make up for the security flaws in the blockchain. Secondly, we summarize the developing secure multi-party computing technology based on blockchain, which are the Zero-knowledge proof scheme, the secret sharing scheme, and the homomorphic encryption scheme. At the same time, we have conducted a security analysis of the multi-party computing technology in the blockchain, and believe that these three technologies can well solve the privacy protection problem in the blockchain. Finally, we look forward to the development trend of the secure multi-party computing in the blockchain, which is expected to solve the problems of poor scalability, key distribution, and non-resistance to quantum attacks. Although the secure multi-party computing technology in the blockchain is still in the development stage, the combination of cryptography and blockchain will become the mainstream development trend in the future.


Since the fingerprint image is quasi-periodical, to reduce the True Rejection Rate (TRR) and the Fault Acception Rate (FAR) of image matching, this paper presented a new deflection angle detection method for two fingerprint images based on the character ring of image amplitude-frequency figure. First, rotation and translation between the two images are separated in theory. Then character rings are extracted respectively and coordinate transformation is taken. Thus the offset is calculated by phase correlation algorithm and turned into deflection angle. Matching experiment using this method shows that the TRR is 0.7137% and the FAR is 0.


Aa attempt was made la the preseat study to Investigate conditioned generalization of the GSR along a subjective pitch continuum. With this purpose in mind, Hovland's classical generalization experiment to various frequencies of sound was, in part, repeated, using the "mel" (ratio) rather than the "jnd" (con fusion) scale. Following Stevens* basic assumption of equivalence, on metathetic continua, between these two subjective scales for pitch, it m s hypothesized that the slope of the generalization gradient would be sim ilar in shape to that obtained by Borland, ie ., negatively accelerated. Using electric shock as the conditioned stimulus, 22 SS were con ditioned to respond to a tone of 1000 mels in pitch, and tested for generalization at 600 and 280 mels. In assessing the date, statistically, significant generalization effects were found. When mean GSR values were plotted, the resulting group curve approached Borland's exponential function. Individual gradients also followed (he same pattern, with no statistically significant departures from the group curve. On the basis of this investigation, it was concluded that (a) generaliza tion occurs to subjective pitch, and (b) the shape of the generalization gradient is the same when pitch is scaled in either jnd or mel units. This conclusion lends support to Stevens' suggestion of the equivalence of confusion and ratio scales on metathetic continua. The findings further confirm the validity of Hovland's study and its importance to learning theory in general. iii Reproduced with permission of the copyright owner.

The diagnosis of primary mitochondrial myopathy is often delayed by years due to non-specific clinical symptoms as well as variable testing of mitochondrial disorders. The aim of this review is to summarize and discuss the collective findings and novel insights regarding the diagnosing, testing, and clinical presentation of primary mitochondrial myopathy (PMM). PMM results from a disruption of the oxidative phosphorylation (OXPHOS) chain in mitochondria due to mutations in mitochondrial DNA (mtDNA) or nuclear DNA (nDNA). Although there are many named syndromes caused by mitochondrial mutations, this review will focus on PMM, which are mitochondrial disorders mainly affecting, but not limited to, the skeletal muscle. Clinical presentation may include muscle weakness, exercise intolerance, myalgia, and rhabdomyolysis. Although skeletal muscle and respiratory function are most frequently affected due to their high energy demand, multisystem dysfunction may also occur, which may lead to the inclusion of mitochondrial myopathies on the differential. Currently, there are no effective disease-modifying treatments, and treatment programs typically only focus on managing the symptomatic manifestations of the disease. Although the field has a large unmet need regarding treatment options, diagnostic pathways are better understood and can help shorten the diagnostic journey to aid in disease management and clinical trial enrollment.


This paper is concerned with regression models of time series data, where the data relate to market level aggregates not to individual farms or groups of farms. It presents ideas and preliminary explorations rather than final results. Some aspects of Nerlove's agricultural supply response model are examined, and some conceptual and practical problems discussed. Two general models are then proposed, one for annual crops and one for livestock products. In the time available little empirical work could be undertaken, so that the usefulness, or otherwise, of the thoughts and models presented rests on rather little evidence.


An indoor pot experiment was conducted to study the effects of exogenous cysteine,glutamate,glycine,and their combinations on the Solanum nigrum pytoremediation of Cd-and PAHs contaminated soils.Single factor treatments with test amino acids had less effects on the S.nigrum plant height and its shoot dry weight(P0.05),while multi-factor treatments promoted the plant height and shoot dry weight significantly(P0.05).All the treatments increased the Cd uptake and accumulation by the plants,with the extraction ratios of plant Cd in treatment cysteine reached as high as 1.80% and 1.83%,being 0.80-fold and 0.83-fold higher than the control,respectively.The combined application of cysteine,glutamate,and glycine promoted the removal of soil Cd and PAHs,with the best effect in treatment 0.3 mmol·kg-1 cysteine+0.3 mmol·kg-1 glutamate+0.3 mmol·kg-1 glycine,in which,the Cd concentration in plant shoot and the removal rate of soil PAHs increased by 1.26-fold and 4.46-fold,respectively,compared with the control.It was suggested that exogenous cysteine,glutamate,and glycine could promote the phytoremediation of low concentration Cd-PAHs contaminated soils,and have a promising future in contaminated soil phytoremediation.


The paper outlines a general procedure to estimate the wind dynamic stresses in hyperbolic cooling towers on the basis of a statistical dynamic approach. Using wind tunnel measurements of pressure fluctuations and assuming that resonance is negligible, predicted wind stresses agreed with measured stresses on an aeroelastic model. It is shown that wind coupling responses reside essentially in the first, second, and third circumferential harmonic modes and that (138 m) 451 feet between modes is important. The procedure is applied to (138-m) 451-ft tower, fixed or on columns. Results show that static and dynamic stresses are of the same order of magnitude.

This study is a preliminary attempt to ascertain insights into diasporic Persian/Second-Temple period ideas concerning Jewish identity. Through the book of Esther this study utilizes the methodological tool of literary characterizations as a means for gaining insight into the narrator's conceptual framework. The first section highlights some of the important recent Esther studies, along with studies concerned with sociological questions and the Hebrew bible. Section two presents a broad discussion of the sociological and literary concerns for this study. The third section presents a study on the characterizations of the story's co-protagonists, Esther and Mordecai. Two aspects of characterization, the narrator's primary description and descriptions of character reactions and interactions, are used to build a sketch of the co-protagonists and suggest possible sociological readings. Finally, section four highlights needed further studies in developing the initial questions of diasporic identity highlighted here.

Objective: To evaluate the shear bond strength effect of silane coupling agents between composite resin and porcelain surface.The use of CLEAFIL REPAIR to restore accidental porcelain fracture of PFMC was estimated,so clinical reference was provided.Methods: One way was scientific research.20 porcelain samples were divided randomly into 2 groups.After surface treatment,the study group was dealt with mixture of silane coupling agents and dentin conditioner.The porcelain surface of control group was disposed with dentin conditioner.Then,all of the samples were restored by CLEARFIL REPAIR system.After 24 hours stored in 37℃ distilled water,AG-10TA universal testing machine was used to test the shear bond strength between composite resin and porcelain surface.The data were analyzed by t test.The other way was clinical study.40 patients were chose,whose PFMC were fractured.CLEAFIL REPAIR was used to restore.These patients were inspected after 2 years.Results: The shear bond strength in silane coupling agents group was stronger than the one without silane coupling agents,and there was significant difference.After 2 years,87.5% of the clinical patients were successfully restored,and 12.5% of them were failed.Conclusion: silane coupling agents could effectively increase the shear bond strength between composite resin and porcelain surface.The effect of CLEARFIL REPAIR for porcelain restored was advisable.


We expand the classic variational formulation of $-\log\mathbb{E}\left[e^{-f}\right]$ to the case where f depends on a diffusion, and not only a on Brownian motion, while decreasing the integrability hypothesis on f. We also give an entropic characterisation of the invertibility of a perturbation of a diffusion and discuss the attainability of the infimum in the aforementioned variational formulation.


Users utilize web applications to perform everyday tasks in order to achieve personal goals. Personalized Web-Tasking (PWT) is the automation of such web interactions while exploiting personal context to enrich users experience. However, web-tasking is affected by unpredictable context behaviour -- environment, user, and infrastructure -- and situational changes. Given that current web systems are challenged to respond effectively to such changes, we proposed to design PWT applications as self-adaptive software systems that exploit personal context to deliver user-centric functionalities. This paper presents our first approach implementing PWT applications using a grocery shopping web-tasking scenario. Our prototype PWT system transforms web-tasking knowledge information (i.e., user's web interactions) into RDF graphs (i.e., runtime models that contain the user's web-tasking). We conclude our paper with a discussion about our results and implementation challenges.


Spatial patterns of canopy tree distribut{on were analyzed through the Box Counting Method in fractal geometry. A map showing the position of 4102 individual canopy trees, belonging to 55 species, was compiled from an inventory of a fourteen hectare research plot, established in an evergreen eak forest, in Kasugayama Ferest Reserve, Nara City, western Japan, in 1991, A newly proposed iractal model allows the saturation of the number of boxes in smaller box sizes, and was successfully used for the calculation of fractal dimensions of sixteen common species, with a sufficient sample size for computation. The calculated dimensions were in a range between 1.I9 of Chainaempan's obtusa Sieb. et Zucc. and 1.73 of Querctts salicina Blume, and their variations among species were compared with the dimensions of valley and ridge (1.43) lines. Larger fractal dimensions tended to be confined to a species with a wider distribution and with habitat less dependent on topography. Smaller fractal dimensions were observed from species with patchy distribution. Species with intermediate fractal dimensions had a distribution pattern fairly dependent on a valley or ridge site. In conclusion, fractal geometry is applicablc to the spatial patterns of forest trees and results in fractal dimensions which appear to indicate a degree of topographic dependency in species' distribution.


LabVIEW uses the graphical modular programming language to design the modularized program.The virtual test system constructed by LabVIEW has the strong point of the facility to extend the program and to upgrade the function.Aiming at the defect that the existing AE test instrument cannot specially detect the AE signal parameters for the failure of the sliding bearings,taking LabVIEW as the software platform,the AE test system for the failure of the sliding bearings was developed and the efficiency of the system is proved.


We investigated the effects of treatment from murine microglial cells with agonists of TLR2, TLR4 and TLR9. For this reason murine microglial cell cultures were applied. We used the TLR agonists Pam3Cys, HKAL (TLR2), pneumolysin, LPS (TLR4) and CPG (TLR9) Stimulation of murine microglial cells with different TLR agonists led to the release of NO and TNF-a. By using different concentrations of TLR agonists dose-response-relations for the release of NO and TNF-a could be displayed. Based on the EC50 the potencies of TLR ligands could be evaluated.
LPS was most potent in releasing NO followed by pneumolysin, CPG and Pam3Cys.
For TNF-a releasing , LPS was also most potent followed by pneumolysin and CpG. Pam3Cys dissolved not optimal, probably for this reason no maximum stimulation was reached by administrating Pam3Cys. Therefore the EC50 of TNF-a release could not be estimated.
EC50 for TNF-a release was higher than the respective EC50 for NO release in each case. Treatment with HKAL led to a high NO and TNF-a release. Direct comparison of HKAL`s potency with the other ligands is not possible, because the concentration of HKAL is measured in cells/ml but concentrations of Pam3Cys, Pneumolysin and LPS is measured in µg/l.
Stimulation of microglial cells via different TLR resulted in approximately equal amounts of NO and TNF-a.
Costimulation of microglial cells with concentrations of two TLR agonists, which led to maximum NO production on his own, did not further increase NO release.
Low doses of Pneumolysin resulted in an immunstimulating effect. Maximum stimulation, measured by the increase of NO production, was observed by a Pneumolysin concentration of 0,3 µg/ml (6nM). Definite cytotoxicity was established by concentrations of 3µg/ml resp. 10µg/ml (60nM resp. 200nM) by means of signigficantly lower NO release. Pneumolysin caused cell damage was showed by Isolectin-B4 staining. No cytotoxicity could be observed by the other ligands in high concentrations.
Treatment of TLR deficient microglial cells with specific TLR4 agonists Pneumolysin and LPS led to a significantly lower NO release in comparison to wildtype cells.
In conclusion: Stimulation of microglial cells via different TLR results in approximately equal amounts of NO and TNF-a release.
Costimulation with two TLR agonists at submaximum concentrations led to additive or supraadditive effects.
Not only bacterial products but also endogenous compounds act as agonists of TLR.
The additive effect of stimulating more than one TLR increases not only sensitivity of microglial cells during infections, but may also entail interactions among exogenous and endogenous agonists of TLR.This may be one reason for the exacerbation or induction of autoimmun diseases by infections.


Although people can improve the using rate of resources and throughput of system by means of the concurrency of multiple pro cesses in multiprogramming system,deadly lock can still occur due to improper resource allocation and illegal execution sequence.Deadly lock is unavoidable.People can only improve the design of the all kinds of functions architecture of OS to decrease the occurrence of dead ly lock.The thesis discusses some means to avoid and release deadly lock from the reasons and conditions through some simple examples.


While credit plays an instrumental role in housing price dynamics, existing work has produced conflicting evidence of its real impact. This paper reconciles various inconclusive findings via a disaggregation strategy to decompose aggregate credit into credit-to-the-real economy (cr) and credit-to-the-asset markets (cf ). We argue that these two credit components exert theoretically expected and distinct impacts on housing prices, identified separately through a housing demand and a housing supply credit-circulation channel. Using an international panel dataset and treating for periodic cycles, our panel VAR estimations show that cr and housing prices depict a mutually reinforcing positive relationship. However, cf exerts a negative but negligible impact on housing prices in the short-run; it has a strong and positive effect in the long-run. Further, controlling for effects of economic policy uncertainty strengthens the interactions between housing prices and the two credit components. Our results are robust and suggest that close monitoring of credit allocation to housing demand and supply sides, as well as the extent of pump-priming resource allocation to the real economy, should be of interest to policymakers.

The vigorous growth of the Chinese economy together with its successful increasing role in international trade has raised fears of deindustrialization among developing countries. This study exploits the large increase in the international trade exposure of the Brazilian economy during 2000–2012 to assess the impacts of trade on its manufacturing sector. In this period, import penetration increased by 25%, and at the same time, the Chinese share of the import penetration increased from 3% to 20%. Using household survey data that encompass both formal and informal workers, this paper's estimates indicate that a higher import penetration reduces the employment level and the informality share. The impacts of Chinese imports are found to be even stronger on those outcomes. The hourly wage appears to not be affected by any of the trade environment variables. The new macroeconomic policy implemented in 2008 magnified the negative effects of imports on the employment level. The results presented in this paper are found to be robust to endogeneity concerns, which are addressed using instrumental variable approach.


The past decade has witnessed a momentous transformation in the way people interact, create and exchange information. Content is now coactively produced, shared, classified, and rated on the Web by millions of people, while attention has become an ephemeral and valuable resource that everyone seeks to acquire. This talk will describe our research on the dynamics of attention, how it plays a crucial rule in the generation of content, and the roles that popularity and novelty play in eliciting attention in the Web.


One of the uses of medical data from diabetes patients is to produce models that can be used by medical personnel to predict and identify diabetes in patients. Various techniques are used to be able to provide a diabetes model as early as possible based on the symptoms experienced by diabetic patients, including using machine learning. The machine learning technique used to predict diabetes in this study is extreme gradient boosting (XGBoost). XGBoost is an advanced implementation of gradient boosting along with multiple regularization factors to accurately predict target variables by combining simpler and weaker model set estimations. Errors made by the previous model are tried to be corrected by the next model by adding some weight to the model. The diabetes prediction model using XGBoost is shown in the form of a tree, with the accuracy of the model produced in this study of 98.71%


Background: The most prevalent form of exotropia is intermittent exotropia. The effect of muscle recession can be predicted using the limbal insertion distance (LID). Objective: This study aimed to assess the treatment of intermittent exotropia (IXT) among both children as well as adults assembled on lateral rectus muscle LID using bilateral lateral rectus (LR) recession. Patients and methods: 46 participants ranged in age from 5 to 30 years old. Patients were separated into groups based on age. Group I included 35 patients (76.1%) with a mean age of 10.26 ± 4.11 years and group II included 11 patients (23.9%) older than 17 years (23.55 ± 4.8). All patients were operated either bilateral or unilateral LR recession to alleviate exotropia under general anesthesia based on preoperative angle of deviation. Results: Mean dose-response differed significantly between groups which was significantly lower among patients older than 17 years. The mean dose-response was 4.73 and 4.4 in group I and group II respectively. Preoperative angle deviation, limbus insertion distance, and amount of recession all exhibited a strong positive significant correlation with the mean dosage response. Both preoperative angle deviation, LID, and amount of recession were found to exhibit a strong positive significant correlation with the mean dose-response. Conclusion: For intermittent exotropia treatment, preoperative lateral rectus muscle weakness, angle deviation, limbus insertion distance, and recession amount are all positively correlated with the mean dose-response in both eyes and in one eye separately.


The objective of the current study was to identify the operational model of agonism for the EEG effects of opioids. Unbound biophase concentration-EEG effect relationships of the opioids alfentanil, fentanyl, sufentanil, morphine, butorphanol and nalbuphine were simultaneously analysed with a) the Hill equation and b) the operational model of agonism. Individual concentration-effect relationships were analysed with the Hill equation and showed that large differences in potency (EC50 range 0.22 – 1215 nM) and intrinsic efficacy (α range 0.11 – 1). Subsequent analysis with the operational model of agonism was performed with the values of the system maximum Em (123 μV) and n (1.44) constrained to the values of alfentanil which displayed the highest intrinsic activity. The values of the in vivo affinity parameter pKA ranged from 5.64 (morphine) to 9.15 (sufentanil) and of the efficacy parameter log τ from 0.421 for alfentanil to -0.342 for nalbuphine. When the estimated in vivo pKA values were correlated with the in vitro pKi values, indications for two distinct subpopulations were obtained. In addition, a poor correlation was observed between the in vitro Na/GTP-shift and the in vivo log τ indicating that the in vitro efficacy measures cannot predict the in vivo EEG effect. These observations might be explained by 1) the involvement of active transport processes in distribution from blood to biophase, 2) the existence of μ-opioid receptor subtypes and 3) the interaction with other types of opioid receptors.

Fingerlings of Channa punctatus are exposed to 12 mg/l zinc sulphate for 31 d at daily feeding. From the 19th day a significant decrease of growth (increase of weight) by 7 … 8 % as compared with the untreated control fishes was found. After exposure for 30 d the RNA- and protein-contents of the muscles are lower by 10 and 13 %, respectively.


The purpose of this paper is to point out that an asymptotic rule "A+B/u" for the ultimate ruin probability applies to a wide class of dependent risk models, in discrete and continuous time. Dependence is incorporated through a mixing approach among claim amounts or claim inter-arrival times, leading to a systemic risk behavior. Ruin corresponds here either to classical ruin, or to stopping the activity after realizing that it is not pro table at all, when one has little possibility to increase premium income rate. Several special cases for which closed formulas are derived, are also investigated in some detail.


This paper proposes a set of efficient primitives for process synchronization in multiprocessors. The only assumptions made in developing the set of primitives are that hardware combining is not implemented in the inter-connect, and (in one case) that the interconnect supports broadcast.
The primitives make use of synchronization bits (syncbits) to provide a simple mechanism for mutual exclusion. The proposed implementation of the primitives includes efficient (i.e. local) busy-waiting for syncbits. In addition, a hardware-supported mechanism for maintaining a first-come first-serve queue of requests for a syncbit is proposed. This queueing mechanism allows for a very efficient implementation of, as well as fair access to, binary semaphores. We also propose to implement Fetch and Add with combining in software rather than hardware. This allows an architecture to scale to a large number of processors while avoiding the cost of hardware combining.
Scenarios for common synchronization events such as work queues and barriers are presented to demonstrate the generality and ease of use of the proposed primitives. The efficient implementation of the primitives is simpler if the multiprocessor has a hardware cache-consistency protocol. To illustrate this point, we outline how the primitives would be implemented in the Multicube multiprocessor [GoWo88].


Abstract : A statistical study of training- and job-performance measures of several hundred Air Traffic Control Specialists (ATCS) representing Enroute, Terminal, and Flight Service Station specialties revealed that training-performance measures reflected: (1) performance in the training laboratories; (2) academic performance; and (3) instructors' opinions. In the job-performance area, supervisors seemed to be evaluating (1) overall performance of an ATCS; (2) his interpersonal orientation; (3) job orientation; (4) job potential; (5) job performance; and (6) emotional stability. By examining the practicability of the job-performance measures by training performance, aptitude tests, previous job-relevant experience, and demographic characteristics, evidence was elicited that: (1) the ATCS specialties differ in the characteristics required for job performance; (2) Terminal supervisors more consistently evaluate their ATCS in comparison with Enroute supervisors; (3) opinions of the ATCS training-course instructors are the best predictors of subsequent job performance; and (4) aptitude tests, previous job-relevant experience, and age at entry into training are related to job performance but not at very high levels.

AbstractA simple method is presented for determining the peak horizontal acceleration of nonstructural components attached to the floor system of multistory structures subjected to strong ground motions. The procedure was developed for nonstructural components based on shake-table data measured on the floor diaphragms of 30 small-scale reinforced concrete test structures. The observed response led to a general expression that directly accounts for the level of inelastic response of the structures. Floor acceleration data from existing instrumented buildings during strong seismic events were used to test the validity of the method. The method was also assessed analytically using acceleration data calculated after nonlinear dynamic analyses of 6- and 12-story reinforced concrete frames subjected to a suite of 10 ground motions scaled to three intensity levels to cause varied degrees of inelastic response in the frame elements. These analyses allowed the inclusion of flexible nonstructural components in the ...


PURPOSE: A hand-off control system is provided to reduce the generation rate of a compulsory cut of a communication by considering an allowable time interval from the hand-off request by a mobile station to the completion of hand-off treatment. CONSTITUTION: An intensity of a signal received from a base station(20a) is measured periodically at a mobile station(10), and a relative change rate of the received signal intensity is calculated during every measuring time, and the measurement result and the calculation result are informed to the base station and a base station of hand-off movement place. In case that the mobile station requests hand-off, a call of the mobile station is arranged in an appropriate queue among a plurality of queues having priority on the basis of the relative change rate of the call. The call is rearranged in a queue corresponding to a new relative change rate whenever the relative change rate is renewed. The sequence of standby in the queue is determined on the basis of the received signal intensity in the mobile station.


The favorable electron optical properties of carbon nanotubes (CNTs) have been studied in detail, but the application to electron sources has been limited by the complexity of the fabrication process. We report the use of Plasma Enhanced Chemical Vapor Deposition (PECVD) for the direct deposition of multi-walled CNTs onto the apex of sharply etched tungsten tips, aligned to the vertical axis of the tips. We show that these emitters have excellent stability.


Traffic management measures are often used to reduce traffic demand in urban areas to promote public transport and other modes such as walking and cycling and to improve the urban environment. Use of traffic simulation models is often made to test and assess the impacts of alternative traffic schemes. Experience shows that the criteria for selecting one alternative among others tested are based on functional parameters of the network such as speed, flow, vehicle delays at intersections, journey times and overall capacity of the network, but not on impacts on road safety. The paper presents the first results of a research effort that attempts to evaluate the safety effects of different traffic management measures in urban areas, by utilising the outputs from the model test runs. Suitable safety models that can be fed by the outputs are employed for this reason. The focus of the paper is on the methodological issues rather than on the results. The conclusions are encouraging with respect to the approach itself but stem questions as to the safety effect of the traffic schemes. For the covering abstract see ITRD E111131.

Background: Depression and antidepressant use is highly prevalent among U.S. women and may be related to increased breast cancer risk. However, prior studies are not in agreement regarding an increase in risk. Methods: We conducted a prospective cohort study within the Nurses' Health Study (NHS) and NHSII among females age 25 and older. Over more than 10 years of follow-up in each cohort, 4,014 incident invasive breast cancers were diagnosed. We used Cox proportional hazards regressions with updating of exposures and covariates throughout follow-up to estimate HRs and 95% confidence intervals (CIs) for associations between clinical depression and antidepressant use with invasive breast cancer risk. Analyses were repeated separately for in situ disease, as well as stratified by estrogen receptor (ER) subtype and menopausal status at diagnosis. Results: No statistically significant associations were observed between clinical depression (HR for reporting ≥3 times vs. 0, 1.13; 95% CI, 0.85–1.49) or antidepressant use (HR for reporting ≥3 times vs. 0, 0.92; 95% CI, 0.80–1.05) and invasive breast cancer risk in multivariable analyses. Likewise, we observed no significant associations between clinical depression or antidepressant use and risk of in situ, ER+, ER−, premenopausal, or postmenopausal breast cancer. Conclusions: In the largest prospective study to date, we find no evidence that either depression or antidepressant use increase risk of breast cancer.

A significant proportion of patients who survive coronavirus disease of 2019 (COVID-19) develop a constellation of life-altering symptoms that persist long after the initial infection has resolved. This post-COVID-19 syndrome may result from the development of autoreactive IgG antibodies that cause inflammation and tissue injury. In this commentary, we suggest that efgartigimod, a drug approved for the treatment of generalized myasthenia gravis, be tested for use in patients with post-COVID-19. Efgartigimod is a humanized IgG Fc fragment containing five point mutations that significantly increase affinity for the Fc region of the neonatal crystallizable fragment receptor (FcRn). FcRn is involved in the pathogenesis of autoimmune diseases via the IgG recycling pathway because FcRN binds to autoreactive IgG antibodies and prevents the antibodies from being catabolized. Efgartigimod is a modified immunoglobulin that competitively displaces endogenous IgG from FcRn, thus increasing the level of unbound IgG, which is then catabolized and leads to decreased circulating levels of autoreactive as well as normal IgG. We suggest that efgartigimod be evaluated in a random, double-blind placebo-control trial in adults with post-COVID-19 for at least 2 months. If re-purposing this myasthenia gravis-approved drug for post - COVID-19 is successful, additional bioengineered FcRn antagonists should be tested for efficacy in patients with post-COVID-19.


THIAMINE (vitamin B1) is known to affect the metabolism and growth of yeast. It was found to stimulate the growth in concentrations as low as 0 01 ,ug./ml. of culture medium [Williams & Roehm, 1930]. Not every type of yeast, however, is affected in this way, some yeasts responding only very little to thiamine under the usual growth conditions. Similarly some yeasts only are capable of synthesizing thiamine from comparatively simple media [for lit. see Williams, 1941]. Closely related to the effect of thiamine on growth is its effect on yeast fermentation. This is increased by doses of thiamine of the same order of magnitude as those which stimulate growth [Schultz et al. 1937, 1, 2]. A quantitative test for determining such minute amounts by the yeast fermentation method has been described by Atkin et al. [1939] who found that the addition of 0 010 04 ,ug. of thiamine per 5 mg. yeast (wet weight) suspended in 3 ml. of medium considerably raises the anaerobic C02 output during the 2nd hr. of incubation, and that the increase of fermentation caused by doses of 0.01 to 0-02 ,ug. is proportional to the amount of added thiamine. In this paper the experiments described by Atkin et al. [1939] have been repeated and some more facts have been gained on the effect of thiamine on yeast fermentation. EXPERIMENTAL The experiments were made with ordinary Warburg manometers (conical flasks of about 18 ml.) at 20 and 39°. N2 was freed from traces of 02 by passing it over heated copper. For each vessel 1-5 mg. wet weight of ordinary baker's yeast or Torula utitis were used, suspended in the medium employed by Atkins et al. Their experimental procedure was generally followed except that the volume of fluid per vessel was always kept constant when different amounts of thiamine were tested (vide Table 1). The percentage increase in the rate of fermentation caused by thiamine above that of the control to which no thiamine had been added was plotted against concentration of thiamine.


Abnormalities in water balance are noted in psychiatric patients, particularly those with schizophrenia (1). In chronic psychiatric patients, disturbed water homeostasis is noted in 70% of the cases. In a study of hospitalised psychiatric patients, 6.6% had a history compatible with compulsive water intake and one-half of these had symptoms of intermittent hyponatremia due to transient water retention (2). The underlying disorder causing compulsive water consumption in psychotic patients remains unclear. Impairment in central thirst regulation (1,3) or drug therapy (4) may contribute to an altered sensation of thirst. The triad of psychosis, intermittent hyponatremia and polydipsia is called PIP syndrome (5). Usually, symptoms of this syndrome remain subclinical but fatalities do occur. The most serious complication of primary polydipsia is water intoxication with clinical symptoms like inappropriate behaviour, delusions, hallucinations, confusion and disorientation. We report the case of a 59-year-old man working as a farmer in an isolated village without known psychiatric disorder who was brought to the emergency department with epileptic status. Laboratory tests revealed severe hyponatremia (Na< 110 mEq/dl). Brain CT scan and EEG were normal. Hyponatremia was treated by infusion of hypertonic saline and the patient recovered. History revealed a chronic mild thoracic pain which was fully investigated a year before. By that time, moderate asymptomatic hyponatremia was also noted (120–130– 138 mEq/l), and further investigation of the finding revealed nothing abnormal. An extended cardiologic investigation including coronary angiography and electrophysiological evaluation was performed at the time, with no abnormal findings. Thoracic CT scan revealed a small lesion (1.6 cm) at the lower lobe of the right lung. Bronchoscopy was suggested but the patient did not comply. The finding was re-evaluated 8 months later with a new CT scan and it remained unchanged. Ultrasound of the upper and lower abdomen and Tc-99mMDP bone radionuclide scan were also performed with no significant findings. Since then, the patient was under treatment with verapamil hydrochloride and occasionally NSAIDs. During his admission to our clinic, his serum sodium levels and serum and urine osmolality were at the lower normal values. On the third day, polyuria was noted. Further questioning revealed consumption of large amount of water (>9– 12 l/day as calculated by the doctor). The patient described long-standing high water consumption but failed to be more precise. Although it was difficult to get reliable information from this low socioeducational level patient, a detailed history failed to uncover symptoms of (undiagnosed) hyponatremia in the past. A water-restriction test was performed and a rapid rise of urine osmolality following rise of plasma osmolality was noted. Primary polydipsia was diagnosed as evaluation showed no evidence of adrenal insufficiency, diabetes insipidus, diabetes mellitus or renal disease. On examination, the patient reported the belief that he suffered from cancer and was dying of that soon. On the following psychiatric evaluation, the patient was diagnosed with psychotic disorder, which according to the DSM IV fulfilled the criteria of delusional disorder, somatic type. The patient reported non-bizarre delusions of having a disease (cancer) while no other positive (i.e. hallucinations, disorganised speech, disorganised or catatonic behaviour) or negative psychotic symptoms (i.e. affective flattening, alogia or avolition) have ever been confirmed during the 1.5 years of his delusional disorder. Furthermore, the patient presented with a severe impairment of his occupational life, which was due to the somatic delusion. Apart from that, his functioning was not markedly impaired. Finally, no mood disorder was evident during the period of the delusional disorder and disturbance was not due to the direct physiological effects of substance abuse or to another medical condition. The patient was discharged with specific advice for restriction of water consumption in no more than 1500 ml/day. Correspondence to: Charalampos lydakis, M.

An overview is given on the historical development of the cluster conference series which started at Bohum in 1969. I start with the discussion of the philosophy of Karl Wildermuth and then I make a review on the main subjects and topics in cluster conferences. Since the cluster dynamics is a main nuclear dynamics together with the mean-field dynamics, we see that development of the cluster conference has been along with the rises of many new subjects in nuclear physics itself. Examples of them include superheavy nuclei, nuclear astrophysics, neutron-rich nuclei, cluster-gas states and ab initio calculations. Finally I discuss that more activities in and attention to cluster physics are seen in recent days.


The paleogeography and chronology of the Paleoproterozoic supercontinent Nuna are highly debated. To further test the paleogeography of Australian cratons in the leadup to Nuna formation, we present new paleomagnetic results from two Paleoproterozoic rock formations in North Australia. First, we obtained paleomagnetic directions from the 1825±4 Ma, bimodal Plum Tree Creek Volcanics sequence located within the Pine Creek Inlier of the North Australian Craton. Second, we studied the 1855±2 Ma layered mafic-ultramafic 'Toby' intrusion from the Kimberley Craton (KC). Samples from both study areas reveal high quality, stable, magnetite related characteristic remanent magnetization directions. Combining within-site clustered mean directions, we obtained two paleopoles, which plot proximal to each other in the present day central Pacific Ocean, off the east coast of Australia. These results agree with previous interpretation that the Kimberly Craton was amalgamated with the rest of the North Australian Craton (NAC) prior to ca. 1.85 Ga. Comparing these new results with slightly younger poles from the NAC and slightly older, rotated poles form the West Australian Craton (WAC) reveal a high degree of clustering suggesting very minimal absolute plate motion between ca. 1.9-1.85 and 1.6 Ga before the final amalgamation of Nuna. All available paleomagnetic poles agree with an assembly, or close juxtaposition, of the two major Australian cratons (NAC and WAC) before 1.8 Ga. Furthermore, the individual virtual geomagnetic poles from the potentially slow cooled Toby intrusion show a non-fisherian distribution along a great circle. This spread might be related to previously interpreted major true polar wander events based on Laurentian data, which would be global if such an interpretation is correct. The assembly of proto-Australia prior to ca. 1.85 Ga roughly 250 to 300 Myr before the final stage of supercontinent Nuna's amalgamation ca. 1.6 Ga suggests that assembling of major building blocks, such as Australia and Laurentia for the supercontinent Nuna and Gondwana for the supercontinent Pangea, is an important step in the formation of supercontinents.


To obtain a rotary motor's position, resolver-to-digital conversion conventionally adopts phase-locked loop-based type-II angle tracking observer (ATO), which generally performs well yet incurs steady-state position error when the motor accelerates. It inevitably weakens the motor drive system's performance in applications such as electric vehicle, where the speed changes frequently. This paper proposes acceleration-compensated ATO that utilizes its own estimated speed to generate a signal proportional to the motor's acceleration, and thus, compensate for the position error. First, it is theoretically verified that the proposed ATO can accurately estimate the rotor position of an accelerating motor. Also, its stability condition is deduced. Second, since the proposed observer, a third-order system, is too complicated to analyze directly, first-order and second-order systems are designated to approximate it, respectively, under two certain circumstances. Based on which, a simple guideline is summarized on how to tune the proposed ATO so that it may retain the merits of the conventional one while estimating the rotor position free of steady-state error. Finally, on a resolver mounted on a 20-kW permanent magnet synchronous motor, experiments are carried out. Experimental results demonstrate the ability of the acceleration-compensated ATO to precisely track an accelerating motor's position in comparison with that of its conventional counterpart.

Theoretical models suggest that gene silencing at the nuclear periphery may involve "closing" of chromatin by transcriptional repressors, such as histone deacetylases (HDACs). Here we provide experimental evidence confirming these predictions. Histone acetylation, chromatin compactness, and gene repression in lamina-interacting multigenic chromatin domains were analyzed in Drosophila S2 cells in which B-type lamin, diverse HDACs, and lamina-associated proteins were downregulated by dsRNA. Lamin depletion resulted in decreased compactness of the repressed multigenic domain associated with its detachment from the lamina and enhanced histone acetylation. Our data reveal the major role for HDAC1 in mediating deacetylation, chromatin compaction, and gene silencing in the multigenic domain, and an auxiliary role for HDAC3 that is required for retention of the domain at the lamina. These findings demonstrate the manifold and central involvement of class I HDACs in regulation of lamina-associated genes, illuminating a mechanism by which these enzymes can orchestrate normal and pathological development.


In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of Java, Esterel-like reactivity and synchrony, and the asynchronous de-coupling of CSP all within the Java framework. Using standard Java environments, for specification and modelling, or specialised reactive embedded processors, for high performance implementation, the SystemJ design flow is extremely versatile. With the increasing attention that Java gets in embedded systems, SystemJ comes to address data and control, software and hardware, modelling and implementation in a unified manner


ABSTRACT Using a sample of new ventures in China, this study examined the roles of the two different types of managerial resources, i.e. managerial ties and functional experience, simultaneously and interactively. It suggests that both of them have positive influences on new venture performance, and managerial ties remain the main factor that contributes to firm success. Political ties have a positive effect on sales growth but have an inverted U-shaped relationship with profit growth of new ventures, while the effect of business ties on firm performance is monotonic and positive. Finally, it suggests that the complementary effect occurs between political ties and functional experience, while the substitution effect occurs between business ties and marketing experience.


Objective To study a better method of judging cephalopelvic disproportion on plane pelvic outlet. Methods 200 term pregnant women were enrolled. The way of parturition was determined by comparing circumcircle area of posterior triangle of exitus pelvis with fetal head cross section area and traditional method.

The difference between two methods was statistical significant. Conclusion The method of comparing circumcircle area of posterior triangle of exitus pelvis with fetal head cross section area is a quantitative criteria for iudging trial of labour. It's accuracy of judging trial of labour is high.


This paper presents theoretical and methodological reflections about science and technology heritage in the photographic collection of the Federal University of Pernambuco (UFPE). The UFPE photo collection consists of about twenty thousand photographs, mostly in black and white, produced in the institutional context, between 1946 and 2002. They are photographs that record the moments that the institution considered significant for its history, covering inaugurations, events, buildings, festivals, ceremonies, and other experiences that were considered relevant to be eternalized through the photographic record. After the physical treatment of this collection took place a selection of images that were considered by the authors as related to S & T heritage, it is possible to identify some patterns in the type of photography produced, indicating the predominance of certain cuts of the equity of S & T heritage, or by areas of knowledge, either by way of representation of scientists, is the exclusion of certain areas of knowledge. It is clear, therefore, that this collection, although it was produced for about half a century, and two dozen different photographers, presents imagery buildings that create an idealized representation of science and scientists, shunning science idea as daily work activity, even at a university. This work dialogues especially with the theoretical framework proposed by RIEGL (1999), DELICATE (2008, 2015), PANESE (2007), LOUREIRO (2009), GRANATO (2009) and MANINI (2002), authors who deal with science communication, identification and registration of S & T assets, as well as those who propose specific methodologies for informational treatment of photography. Thus, the work aims to contribute to expanding the discussion of Science and Technology Heritage starting from the photographic document, approached as the S&T object itself.


The majority of looked after children are now in some kind of foster care and carers are expected to cope with many children who have complex needs and challenging behaviour. If foster carers are to take on these increasing responsibilities they clearly require good preparation, comprehensive support and the right kind of training. Yet currently, the structure and quality of training vary significantly, and there is little evidence about the impact of training on foster carers or the children they look after. This article by Andrea Warman, Clare Pallett and Stephen Scott uses evaluation material from a new post-approval training programme for foster carers in Southwark and draws upon education research to argue that there must be more debate about how we train and the role that foster carers could play in training their peers.

Plasma deposition of SiN on silicon substrates in a microwave (2.45 GHz) electron cyclotron resonance SiH4/N2/He, in the ratio 4/10/10, discharge has been investigated as a function of rf (40 MHz) self‐biasing of the sample. Low levels of rf bias (0–10 W) were investigated and are reported in this letter. The effect of bias was measured for the deposited films with respect to refractive index, etch rate in BHF, Si—H bonding, and the intrinsic film stress. All depositions were conducted at or near room temperature to evaluate the effect of the applied rf bias on film density. All parameters examined indicated that low levels of rf bias help prepare a high quality, dense film at very low substrate temperatures.


We present the most recent version of our RoboCube system, a special robot controller hand-tailored for players in the small robots league. The RoboCube is conceptualized to implement players with as many on-board features as possible in an extremely flexible way. For this purpose, the RoboCube provides significant computation power and memory as well as a multitude of I/O interfaces within the space constraints. As it facilitates the use of many sensors and effectors, including their on-board processing, the RoboCube allows us to explore a large number of different robots and team set-ups.
