Towards truthful auction for big data trading

In this paper, we address the issue of data trading in big data markets. Data trading problems have attracted increased attention recently, as the economic benefits and potential of big data trading are substantial and varied. However, how to effectively trade data between the data owners (sellers) and data collectors/users (buyers) is far from settled, and requires careful design. Auction mechanisms have been applied across many fields, and have significant potential to facilitate data transactions in a fair, truthful, and secure way. Nonetheless, a truthful auction must ensure the property of incentive compatibility, meaning that the bidders can obtain highest utility if and only if they submit their bids and asks truthfully. Furthermore, a truthful and fair auction should also protect the optimal auction results from being manipulated by false-name bidding attacks, where users (participants) utilize multiple identities or accounts to influence the auction results. To tackle these issues, we propose a Multi-round False-name Proof Auction (MFPA) scheme, which enables data trading among data owners (sellers) and data collectors (buyers). We prove that our MFPA scheme achieves the properties of incentive compatibility, false-name bidding proofness, and computational efficiency. The experimental results demonstrate that MFPA achieves good performance in terms of social surplus, satisfaction ratio, and computation overhead.
Disease Activity in Systemic Lupus Erythematosus Correlates With Expression of the Transcription Factor AT‐Rich–Interactive Domain 3A

Systemic lupus erythematosus (SLE) is a complex and multifactorial autoimmune disease with striking clinical, immunologic, and genetic heterogeneity, despite nearly ubiquitous antinuclear antibody (ANA) production. Multiple gene polymorphisms have been associated with the disease, but these individually account for only a very small percentage of overall SLE risk. In earlier studies, constitutive expression of the DNA‐binding protein AT‐rich–interactive domain 3A (ARID3a) in transgenic mouse B lymphocyte lineage cells led to spontaneous ANA production and preferential development of B cells associated with production of polyreactive antibodies. Therefore, we undertook this study to determine whether ARID3a was overexpressed in B lymphocytes of SLE patients and whether ARID3a expression was associated with disease severity.
A global localization approach based on relative position relationships of line segments

Scan matching is a method for mobile robot global localization in indoor structured environment. The disadvantages of current methods are low computational efficiency and large probability of error matching in the large-scale environment. In this paper, we proposed a new scanmatching method for global localization with the relative position relationship of complete line segments (CLS) and visible complete line segments (VCLS). The proposed method compared the relative relationship of CLS in local map and VCLS in ordinal global map to avoid excessive coordinate transformation and limits of line segments in matching between the local map and the global map. In the simulations, new method can obviously reduce computation cost in large-scale environment.

Tobacco Control in Turkey.

This report was prepared by WHO within the framework of the Bloomberg Global Tobacco Control Initiative in collaboration with the Ministry of Health and the Tobacco and Alcohol Market Regulatory Authority in Turkey. It outlines the current state of tobacco-smoking in Turkey, including the health and social aspects, epidemiological data and economic, legal and political issues. Turkey, until recently one of the major tobacco-producing countries of the world, has made substantial progress in tobacco control in a short time. The initial efforts of the Ministry of Health in the late 1980s received an impetus when Turkey ratified the WHO Framework Convention for Tobacco Control in 2004. Law No. 4207 of 1996 was substantially amended in 2008 and thus became one of the most advanced tobacco control laws in the world. Even so, smoking is still a serious health problem in the country, with one tenth of all the disabilityadjusted life-years lost due to smoking. About one third of the population smokes, despite a slight decrease over the last 15 years.
Isolation and Characterization of Human Adult Epithelial Stem Cells from the Periodontal Ligament

We report a novel method for the isolation of adult human epithelial stem cells (hEpiSCs) from the epithelial component of the periodontal ligament—the human epithelial cell rests of Malassez (hERM). hEpiSC-rich integrin-α6+ve hERM cells derived by fluorometry can be clonally expanded, can grow organoids, and express the markers of pluripotency (OCT4, NANOG, SOX2), polycomb protein RING1B, and the hEpiSC supermarker LGR5. They maintain the growth profile of their originating hERM in vitro. Subcutaneous cotransplantation with mesenchymal stem cells from the dental pulp on poly-l-lactic acid scaffolds in nude mice gave rise to perfect heterotopic ossicles in vivo with ultrastructure of dentin, enamel, cementum, and bone. These remarkable fully mineralized ossicles underscore the importance of epithelial-mesenchymal crosstalk in tissue regeneration using human progenitor stem cells, which may have already committed to lineage despite maintaining hallmarks of pluripotency. In addition, we report the clonal expansion and isolation of human LGR5+ve cells from the hERM in xeno-free culture conditions. The genetic profile of LGR5+ve cells includes both markers of pluripotency and genes important for secretory epithelial and dental epithelial cell differentiation, giving us a first insight into periodontal ligament–derived hEpiSCs.
Performance recovery of a class of uncertain non-affine systems with unmodelled dynamics: an indirect dynamic inversion method

ABSTRACT This paper presents an output feedback indirect dynamic inversion (IDI) approach for a class of uncertain nonaffine systems with input unmodelled dynamics. Compared with previous approaches to achieve performance recovery, the proposed method aims at dealing with a broader class of nonaffine-in-control systems with triangular structure. An IDI state feedback law is designed first, in which less knowledge of the model plant is needed compared to earlier approximate dynamic inversion methods, thus yielding more robust performance. After that, an extended high-gain observer is designed to accomplish the task with output feedback. Finally, we prove that the designed IDI controller is equivalent to an adaptive proportional-integral (PI) controller, with respect to both time response equivalence and robustness equivalence. The conclusion implies that for the studied strict-feedback non-affine systems with unmodelled dynamics, there always exits a PI controller to stabilise the systems. The effectiveness and benefits of the designed approach are verified by three examples.
Three-State Microwave Tunable Resonator Integrating Several Active Elements on Silicon Technology in a Global Design

This letter addresses a discrete tunable resonator with three different states controlled by a single dc source. The passive components are designed together with the active elements, and both are integrated into a silicon substrate. This method of codesign offers great flexibility in doped area sizing and positioning, allowing for easy management of novel three-state resonators based on two different doped areas (or two different surfaces of semiconductor junctions). The largest area switches from the reverse state (OFF state) to the forward state (ON1 state), with a lower bias voltage than that of the smallest area (ON2 state). This concept offers some new degrees of freedom in the design of tunable microwave devices, showcased in this letter by a demonstrator that can operate at three different resonant frequencies. Good agreement was obtained between simulations and measurements in the three states. Insertion losses are lower than 1.6 dB and the same for the different states.
Rumination, Excessive Reassurance Seeking, and Stress Generation Among Early Adolescent Girls

Nolen-Hoeksema proposed that rumination increases stressful events and circumstances; however, few studies have examined this question. Thus, we explored whether (a) rumination predicted increases in the generation of chronic and acute stress, (b) excessive reassurance seeking (ERS) mediated links between rumination and stress generation, (c) rumination increased exposure to acute independent (uncontrollable) stress, and (d) rumination predicted chronic stress generation in certain domains, but not others. These questions were examined in a 1-year study of 126 early adolescent girls (M age = 12.39 years) using contextual objective stress interviews. Findings indicated that rumination predicted increases in acute dependent interpersonal stress and chronic interpersonal stress, and ERS mediated these associations. Moreover, rumination was not associated with acute independent stress. Finally, the effect of rumination on chronic stress generation was most salient in adolescents’ romantic lives and in parent-adolescent relationships. These findings suggest that ruminators create stressful interpersonal environments.
Robust Secure Beamforming for Cognitive Satellite Terrestrial Networks at Millimeter-Wave Frequency

In this paper, we present a robust beamforming (BF) scheme to improve the physical layer security (PLS) of a cognitive satellite terrestrial network (CSTN) at millimeter wave (mmWave) frequency. By employing the standard recommendations and the mmWave propagation model, a PLS framework is first defined for the CSTN in the presence of multiple eavesdroppers (Eves). A constrained optimization problem is then formulated to maximize the worst-case achievable secrecy rate of the cellular user subject to an allowable interference level for the satellite user. By expressing the imperfect Eve''s channel state information (CSI) as a combination of many given angle-of-arrival (AOA) based discrete sets, we propose a method to transform the worst-case optimization problem into a min-max problem and then develop an iterative BF scheme to yield an analytical solution for the weight vectors. Finally, simulation results confirming the effectiveness and superiority of the proposed BF scheme are provided.
Effects of intracoronary leukotriene D4 infusion on the coronary circulation, hemodynamics, and prostanoid release in porcine experiments.

The effects of leukotriene (LT) D4 (0.5 microgram/min) infusion into the left anterior descending coronary artery (LAD) of anesthetized pigs were studied in the absence or presence of indomethacin (5 mg/kg i.v.). In some pigs, arteriocoronary venous (A-V) blood plasma concentrations of thromboxane B2 and 6-keto-prostaglandin F1 alpha were measured by RIA technique during LTD4 actions. LTD4 changed LAD blood flow at 5 and 30 s, 2, 4 and 5 min by -46% (p less than 0.01), -93% (p less than 0.001), -45% (p less than 0.01), -28% (p less than 0.05) and 16%, respectively. Thus, the coronary constriction disappeared despite sustained LTD4 infusion and was followed by reactive hyperemia. Indomethacin did not affect the coronary flow or hemodynamic responses to LTD4 infusion. The A-V difference in prostanoids did not change during LTD4 administration. Cyclooxygenase products of arachidonic acid may not be responsible for early constriction and later escape phases of LTD4 effects on the coronary circulation. However, intracoronary bolus injection of LTD4 stimulated prostacyclin release from the vasculature in a dose-dependent manner causing significant reactive hyperemia after temporary blood flow cessation. Release of a LTD4-induced vasodilating factor from the coronary vessels unrelated to prostanoids may cause escape from vasoconstriction during LTD4 infusion.
Spatial Distribution of Responses to Simple and Complex Sounds in the Primary Auditory Cortex

The basic functional organization of the cat primary auditory cortex is discussed as it is revealed by electrophysiological studies of the distribution of elementary receptive field (RF) parameters. RFs of cortical neurons have been shown to vary considerably from neuron to neuron; additionally, specific RF properties vary independently. Furthermore, some of the RF properties are nonhomogeneously distributed across the auditory cortex and can be interpreted as forming ‘maps’ that represent specific stimulus information in a topographic way. Accordingly, the functional organization of the primary auditory cortex is interpreted as a series of superimposed independent parameter maps. The consequences of such a layout for the spatial and temporal coding of pure tones and speech sounds is illustrated and ramifications for the interpretation of far-field event-related potentials are discussed.
Effect of folic acid supplementation on cancer risk among adults with hypertension in China: A randomized clinical trial

The relationship of folic acid supplementation with the risk of cancer remains inconclusive. We aimed to evaluate the effects of folic acid supplementation on cancer incidence among adults with hypertension without history of stroke or myocardial infarction (MI) in the China Stroke Primary Prevention Trial (CSPPT). A total of 20,702 hypertensive adults without history of stroke or MI, stratified by MTHFR C677T genotypes(CC, CT and TT), were randomly assigned to receive double‐blind daily treatment with a single pill containing 10 mg enalapril and 0.8 mg folic acid(n = 10,348) or a pill containing 10 mg enalapril alone(n = 10,354). During a median treatment duration of 4.5 years, cancer occurred in 116 participants(1.12%) in the enalapril‐folic acid group versus 116 participants(1.12%) in the enalapril group (HR, 1.00; 95%CI, 0.77–1.29). There was also no significant difference in the HRs for specific types of cancer(esophageal, gastric, breast, lung, colorectal, head and neck, liver and gynecologic cancer or lymphoma) or cancer mortality(HR, 1.05; 95%CI, 0.69–1.58). For participants not receiving folic acid treatment (enalapril only group), MTHFR 677 TT genotype was an independent predictor of total cancer risk compared to CC genotype (HR, 1.86; 95%CI, 1.07–3.22). Consistently, a beneficial effect was observed in participants with MTHFR TT genotype and low folate levels (<9.0 ng/mL; HR, 0.47; 95%CI, 0.24–0.94). There is no evidence that 0.8 mg daily folic acid supplementation can increase the risk of cancer incidence among adults with hypertension without history of stroke or MI in China. Our data suggest a protective effect in participants with MTHFR TT genotype and low folate levels.
A simple and effective strategy to reduce switching losses under FS-MPC based on dynamically changing voronoi diagrams

Finite Set Model Predictive Control (FS-MPC) is a powerful and popular strategy to control power electronic converters. One important aspect of FS-MPC is to limit switching losses while tracking a given reference. This is typically achieved by including in the cost function an explicit measure of switching losses alongside the tracking error. Appropriate weighting coefficients to these two different measures are typically assigned by trial and error. The paper proposes a novel and very effective way to reduce switching losses without penalising them explicitly in the cost function. This is achieved by virtue of fictitious voltage states, which change their positions depending on the currently chosen switching state. An implementation algorithm proposed in the paper is based on principles of computational geometry, specifically, Voronoi diagrams. The algorithm is very efficient and poses almost no additional computational burden compared to standard quadratic cost function. Its application significantly reduces switching losses of FS-MPC without a major penalty in terms of its harmonic distortion. Moreover, the paper shows that the proposed algorithm can be easily combined with other advances recently developed around MPC. The paper presents extensive simulation results showing the advantages of the proposed method and comparing the performance of its various options.
Towards a drug information interoperability mechanism

The diversity of drug information is encountered among the general public such as patients, and the health community. In this case, are doctors, pharmacist assistants, pharmacists, and pharmaceutical installations, which provides a complex information exchange feature in terms of drugs naming as well as active substance content, indications, side effects and etc. Health care stakeholders have build web services and dynamic website according to their individual needs and not yet integrated. A drug Information application is available in the pharmacy for both private and public, they are developed using different database structure, so a drug information interoperability mechanism is required without having to change the database structure that has been built. The proposed research method is implementing semantic approach and ontology.
Are acantholysis and transglutaminase inhibition related phenomena?

BACKGROUND The loss of intercellular cohesion among keratinocytes (acantholysis) may be considered the histologic marker of pemphigus. Many drugs, especially thiol drugs, proved to be able to provoke in vitro acantholysis by biochemical mechanisms interfering with the disulfide and thiol group balance. As to nonthiol drugs, the pathomechanism of acantholysis is still unexplained. OBJECTIVE To explain the molecular mechanism of enalapril-induced acantholysis a potential link between transglutaminase (TGase) activity and the effects of this drug was investigated. METHODS TGase activity in extracts from human breast skin cultured in the presence of thiopronine, captopril and enalapril were evaluated in vitro. The acantholytic potential of cystamine, a known TGase inhibitor, was also investigated. RESULTS Enalapril, the most powerful acantholytic drug in vitro, was found to inhibit both the purified enzyme and the TGase activity in the extracts from cultured human breast skin explants. Kinetic studies showed that enalapril inhibition was competitive with respect to the amino acceptor substrate and uncompetitive with respect to the amino donor substrate. Moreover, an acantholytic effect of cystamine on explants of normal human skin was shown. CONCLUSIONS These results suggest that acantholysis and the inhibition of TGase activity could be two related phenomena.
LINEAR BOLTZMANN EQUATION AND FRACTIONAL DIFFUSION

Consider the linear Boltzmann equation of radiative transfer in a half-space, with constant scattering coefficient \begin{document} $\sigma$ \end{document} . Assume that, on the boundary of the half-space, the radiation intensity satisfies the Lambert (i.e. diffuse) reflection law with albedo coefficient \begin{document} $\alpha$ \end{document} . Moreover, assume that there is a temperature gradient on the boundary of the half-space, which radiates energy in the half-space according to the Stefan-Boltzmann law. In the asymptotic regime where \begin{document} $\sigma\to+∞$ \end{document} and \begin{document}$ 1-\alpha \sim C/\sigma$ \end{document} , we prove that the radiation pressure exerted on the boundary of the half-space is governed by a fractional diffusion equation. This result provides an example of fractional diffusion asymptotic limit of a kinetic model which is based on the harmonic extension definition of \begin{document} $\sqrt{-\Delta}$ \end{document} . This fractional diffusion limit therefore differs from most of other such limits for kinetic models reported in the literature, which are based on specific properties of the equilibrium distributions ("heavy tails") or of the scattering coefficient as in [U. Frisch-H. Frisch: Mon. Not. R. Astr. Not. 181 (1977), 273-280].
Face direction recognition system for robot control system using fingertip gesture

The face direction recognition system using “Intel RealSense SR300” has been developed to support the fingertip gesture recognition system. Face direction (Front, Rightward, Leftward) is able to be recognized from the angle in the yaw direction out of the three-dimensional angle information of the user's face. The authors conducted experiments on performance comparison with the face direction recognition system using a webcam. As a result, the comfort of the operation of the mobility robot by the fingertip gesture was improved.
Adaptations in muscle oxidative capacity, fiber size, and oxygen supply capacity after repeated-sprint training in hypoxia combined with chronic hypoxic exposure.

In this study, we investigate adaptations in muscle oxidative capacity, fiber size and oxygen supply capacity in team-sport athletes after six repeated-sprint sessions in normobaric hypoxia or normoxia combined with 14 days of chronic normobaric hypoxic exposure. Lowland elite field hockey players resided at simulated altitude (≥14 h/day at 2,800-3,000 m) and performed regular training plus six repeated-sprint sessions in normobaric hypoxia (3,000 m; LHTLH; n = 6) or normoxia (0 m; LHTL; n = 6) or lived at sea level with regular training only (LLTL; n = 6). Muscle biopsies were obtained from the m. vastus lateralis before (pre), immediately after (post-1), and 3 wk after the intervention (post-2). Changes over time between groups were compared, including likelihood of the effect size (ES). Succinate dehydrogenase activity in LHTLH largely increased from pre to post-1 (~35%), likely more than LHTL and LLTL (ESs = large-very large), and remained elevated in LHTLH at post-2 (~12%) vs. LHTL (ESs = moderate-large). Fiber cross-sectional area remained fairly similar in LHTLH from pre to post-1 and post-2 but was increased at post-1 and post-2 in LHTL and LLTL (ES = moderate-large). A unique observation was that LHTLH and LHTL, but not LLTL, improved their combination of fiber size and oxidative capacity. Small-to-moderate differences in oxygen supply capacity (i.e., myoglobin and capillarization) were observed between groups. In conclusion, elite team-sport athletes substantially increased their skeletal muscle oxidative capacity, while maintaining fiber size, after only 14 days of chronic hypoxic residence combined with six repeated-sprint training sessions in hypoxia. NEW & NOTEWORTHY Our novel findings show that elite team-sport athletes were able to substantially increase the skeletal muscle oxidative capacity in type I and II fibers (+37 and +32%, respectively), while maintaining fiber size after only 14 days of chronic hypoxic residence combined with six repeated-sprint sessions in hypoxia. This increase in oxidative capacity was superior to groups performing chronic hypoxic residence with repeated sprints in normoxia and residence at sea level with regular training only.
