Dr I W Caldweli: Some years ago in Lincolnshire I had a case similar to the one presented today, whose skin lesions were of the erythema annulare centrifugum type on the trunk with some scaling. On the basis of another case seen elsewhere I referred him for a chest X-ray which showed a localized shadow. At operation a bronchial neoplasm was removed. The eruption quickly disappeared and a two-year follow up showed no recurrence of either condition.


The bonding properties of PMMA-microstructures on Ti-coated Cu-substrates after an oxidative treatment in alkaline hydrogenperoxide solution were investigated. In order to clarify the basic mechanism, surface analytical investigations by XPS-, AES-, and depth profile measurements have been performed. It was demonstrated that for optimum bonding a Ti02 surface layer of ca. 30 nm thickness is necessary. Chemical effects as weil as a mechanical bonding with open grain boundary structures (dimensions in the 11m-range) could be ruled out as bondinq mechanisms. A mechanical interlocking of the polymer with micropores (dimensions in the nmrange) of the oxidic overlayer is adopted as the most probable bonding mechanism.

In applications of the gas proportional scintillation counter to the detection of very low energy X-rays, the addition of the light noble gas neon to the usual xenon filling improves the collection of primary electrons that would have originated near the detector window. However, xenon-neon mixtures produce lower electroluminescence yields than pure xenon. The highest electroluminescence yield that can be achieved without jeopardizing the energy resolution is limited by the additional fluctuations introduced by electron multiplication and, consequently these detectors are usually operated at reduced electric fields below the ionization threshold. In this work, a compromise between electroluminescence output and energy resolution is investigated for xenon-neon mixtures at a total pressure of 800 Torr (with 5%, 10%, 20%, 40%, 70%, 90% and 100%Xe), and for 5.9 keV X-rays. Using experimental and Monte Carlo studies, the effects of introducing a limited amount of charge multiplication on the electroluminescence yield and on the detector energy resolution are analysed and discussed, and the optimum operating conditions for gas proportional scintillation work are established.


Spectral Graph Convolutional Networks (GCNs) are generalisations of standard convolutional for graph-structured data using the Laplacian operator. Recent work [26] has shown that spectral GCNs have an intrinsic transferability. This work verifies this by studying the experimental transferability of spectral GCNs for a particular family of spectral graph networks using Chebyshev polynomials. This work introduces two contributions. First, numerical experiments exhibit good performances on two graph benchmarks [13] [19], on tasks involving batches of graphs, namely graph regression, graph classification and node classification problems. Secondly we study a form of data augmentation through structural edge dropout showing performance improvements for GCNs. This work contributes to open research with public implementations of all experiments, enabling full reproducibility.


There were two ways, distribution graphs of sediment yield and muddy and coarse sediment modulus index, applied for determining the key harnessing regions of soil and water loss in the Yellow River basin, both of them needed coarse sediment data. There have been limited accuracy of the ways because there are less stations with sediment particle-size analysis data. The way applied in the paper is determining the key harnessing areas on sediment charge distribution map according to the average sediment charge index of 300 kg/m~(3) in July to August in the water of Hekouzheng to Longmen reach, which is only related to total-load sediment data and of much higher accuracy because there is larger station net density controlling under the stations with total-load sediment data than that controlling under the stations with coarse sediment data. The results shows that there are 113 thousand km~(2) of key harnessing areas in the Yellow River basin, in which there are 57 thousands km~(2) in the region of Hekouzheng to Longmen that is the focal in all the key areas, 32 thousand km~(2) in Jinghe, Luohe and Weihe rivers. 24 thousands km~(2) in Zulihe and Kushuihe rivers.


JOOQ is a query language as derived from SQL or JOOQ is a query language in which SQL uses the objects of OOQ. As there are many issues in integration of java application with various databases via JDBC. This paper proposes a new java library known as JOOQ. The primary aim of JOOQ focuses on integration issues in java programming language. With JOOQ, programmers can write SQL queries in a simpler and faster way. JOOQ thus decreases the programming effort by 10-20% which leads to higher quality of code with low error rate. Thus the application is also significantly light and less prone to errors.


Social law is not just a set of rules governing relations employers and workers, but also a tool of economic policy's where interests address's current law by French social the prism of the major issues in the field. And technical standards will be addressed and understood in their context and perspectives. This path inevitably leads to ideological considerations as social law is directly involved in the permanent confrontation of economic interests social aspirations.

The invention provides a method for realizing regular message pushing in an off-line state. The process is as follows: when a client application is on line, a request is automatically sent out to a server, and a parameter is the serial number of local latest news; when the server receives the request, a response is made to the client with a message in a message library whose serial number is larger than the request parameter; after receiving the server response, the client updates the local message serial number, stores all messages locally, updates a local task list, sets a timer according to notification time specified by the messages, and regular pushing tasks are formulated; and each time a client program is started, a local task list is automatically loaded, and regular pushing tasks are formulated. The method provided by the invention realizes message pushing in the off-line state, and can send notifications regularly according to the time customized by the server. Since message notification is free of limitation of networking conditions, message issuing is relatively flexible, limitation of issuing work in time is reduced, and user experience is greatly improved.


In this thesis we examine the performance of a method to correct for missing response, missing covariates and mismeasured covariates in longitudinal datasets. The method is called Multiple Overimpuatation and was proposed by Blackwell et al. (2015a,b). To our knowledge it was not tested before for longitudinal missing and mismeasured data. Many researchers do not correct for measurement error but only for missing data, probably due to the fact that there exist easy-to-use methods in many statistical programs as multiple overimputation for missing data but no easy-to-use methods for mismeasured data. We conduct a simulation study to show that additional correction for measurement error using Multiple Overimputation improves the results a lot. Even if the exact amount of measurement error is unknown, Multiple Overimputation performs better than normal Multiple Imputation or a Complete Case Analysis. Multiple Overimputation was included in the R-package Amelia II, so researchers do not have to implement anything by themselves and can easily use this new approach to improve their results.

Objective To investigate the optimization of health education in patients with gynecologic cancer and validate the efficacy.Methods Forty-one patients with gynecologic cancer from September 2007 to May 2009 were enrolled and divided into experimental group(n=21,receiving optimized health education) and control group(n=20,receiving regular health education).Mental Status Scale in Non-psychiatric Settings(MSSNS) was used to evaluate the mental status of all the patients at 24 h after hospitalization,24 h before operation,24 h before discharge,and 6 months after operation.Results There were significant differences in depression,anger and total scores between the two groups before operation,before discharge and 6 months after operation(P0.05).The anxiety scores were significant different before discharge and 6 months after operation(P0.05),while the loneliness scores were significant different before discharge between the two groups(P0.05).Conclusion Optimized health education is helpful to alleviate the negative emotion of patients with gynecologic cancer.Moreover,accurate evaluation of mental status ensures that nurses can more comprehensively and accurately understand the patients′ mental status and related causes.This will provide a scientific basis for optimization of health education and improve the work efficiency of nursing.


Through homopolymerization posthydrolysis process, the partially hydrolyzed polyacrylamide (PAM) with super-high relative molecular weight is synthesized by two-stage polymerization method and bifunctional initiator initiates the polymerization, and the effects of polymerization and hydrolysis technical parameters on the relative molecular mass are studied. The results show that optimum polymerization technical parameters are: w(monomer) is 25%, c(initiator) is 45 μmol·L~(-1), c(EDTA) is 0.15 mmol·L~(-1), initiation reaction temperature is 0 ℃. The optimum hydrolysis technical parameters are: Hydrolysis agent is an aqueous alkaline solution containing 50%NaOH, hydrolysis time is 2.5 h, hydrolysis temperature is 90 ℃. Under above condition, the polyacrylamide relative molecular mass (M r) can reach 3.3×10~7 .


This study aimed to evaluate the effects of different concentrations of Forskolin, added to the in vitro culture medium, on the intracytoplasmic lipid content, development and cryotolerance of bovine embryos. COC's (n=848) were submitted IVM during 22h at 38.5°C and 5% CO2 in air, in microdroplets of TCM 199 with 25 mM of bicarbonate, 10% FCS, 0.5 μg/mL FSH and 100 IU/mL hCG, covered with mineral oil. After, the oocytes were subjected to IVF and the presumptive zygotes were cultured in SOFaa (control Group), supplemented on D6 with 2.5 (F2.5 Group), 5.0 (F5 Group) or 10 μM of Forskolin (F10 Group), at 38.5°C and 5% CO2 in air. The embryo development was evaluated on D7, when expanded blastocysts were stained or cryopreserved. For the determination of intracytoplasmic lipid content, a sample of expanded blastocysts (n=99) was stained with the lipophilic dye Sudan Black B and embryos were evaluated under a light microscope running Q-Capture Pro Image Software. The images were converted to grayscale and embryos were delimited for determination of lipid content. The control group was chosen as the calibrator and the gray intensity value of each group was divided by the average of the calibrator to generate the values in arbitrary units. Other expanded blastocysts (n=76) were vitrified by Vitri Inga® - Maringa - PR - Brazil method. The re-expansion rates were evaluated immediately after devitrification (0h) and after 24 hours of in vitro culture in SOFaa medium. The embryo development rate and re-expansion were evaluated by Chi-Square test, while the lipid content was subjected to analysis of variance (ANOVA) followed by Tukey's test (P 0.05) in the blastocyst rates between the Control group (44.9%) and other treatments, but embryo production was lower (P 0.05) to F2.5 (0.9±0.03) and F10 groups (1.06±0.03), however it differed (P<0.05) from F5 group (0.8 ±0.1). Based on these results, F5 group was tested for cryotolerance and it was observed that the rate of re-expansion 24h was greater (P<0.05) in F5 group (72.2%) compared to the Control group (46.2%). In conclusion, treatment with Forskolin at a concentration of 5 μM is effective for reducing the amount of intracytoplasmic lipids and improves cryotolerance of IVP bovine embryos.


The shakedown behavior of butt welded joints under cyclic thermo-mechanical loadings was researched by ABAQUS according to the nonlinear superstition method.Six weld groove shapes of type UV-groove,double U-groove,X-groove,U-groove,single-side welding and V-groove were further studied.Results showed that the type U-groove for the welding thickness 20 mm≤t≤60 mm while the type double U-groove for the welding thickness t60 mm should be utilized for butt welded joints due to the greater shakedown region and thus the greater load carrying capacity under cyclic thermo-mechanical loadings.This study has some guidance significance for engineering designs of butt welded joints of thick pressure vessels and piping.


In interaction or user-centered design practices, it is common to employ interviews and think-aloud techniques to gather data about user behavior. These techniques enable researchers to learn about how users think and use technologies during the design and user testing process. However, such techniques involve accessing audio feedback, which may require workarounds if the researcher identifies as deaf or hard of hearing (DHH). We report on a project led by a DHH researcher in which workarounds to audio access resulted in methodological changes. We discuss the implications of these adjustments.


In a recent study Keimowitz and Ansbacher (4) found that eighth grade boys overachieving in mathematics showed more favorable personality characteristics on the California Psychological Inventory (CPI) than did their underachieving peers. This was consistent with Adler's observation that the child who does well in arithmetic is one who shows independence and social interest, whereas the underachiever reflects a pampered life style (1, pp. 241-242, 401), today frequently called dependency. Might this not hold true also for overachievers and underachievers in general? More specifically, the present study tested the propositions that the high achieving boy will not only score higher on social adjustment, but will also be more highly motivated, more responsible, and more often emotionally engaged in achievement-related tasks than the low achiever.

Nowadays, there are more and more institutional repositories in Spain, as in a large number of countries all over the world, which contains thousands of digital objects in open access, full-text, no-charge and available to free download, print or copy. Nearly every repository is managed and mantained by the library services of the institution they serve. This article explains the reasons for the crisis in the scholarly communication model, the alternative model based on open access to scholarly publication, and the crucial role that the libraries can play in the development of their own digital collections, a challenge and a chance that they can't miss.


Redox-active 6-oxoverdazyl polymers were synthesized via ring-opening metathesis polymerization (ROMP) and their solution, bulk, and thin-film properties investigated. Detailed studies of the ROMP method employed confirmed that stable radical polymers with controlled molecular weights and narrow molecular weight distributions (Ð < 1.2) were produced. Thermal gravimetric analysis of a representative example of the title polymers demonstrated stability up to 190 °C, while differential scanning calorimetry studies revealed a glass transition temperature of 152 °C. Comparison of the spectra of 6-oxoverdazyl monomer 12 and polymer 13, including FT-IR, UV-vis absorption, and electron paramagnetic resonance spectroscopy, was used to confirm the tolerance of the ROMP mechanism for the 6-oxoverdazyl radical both qualitatively and quantitatively. Cyclic voltammetry studies demonstrated the ambipolar redox properties of polymer 13 (E1/2,ox = 0.25 and E1/2,red = −1.35 V relative to ferrocene/ferrocenium), which were consistent with those of monomer 12. The charge transport properties of thin films of polymer 13 were studied before and after a potential of 5 V was applied, revealing a drastic drop in the resistivity from 106−1010 Ω m or more to 1.7 × 104 Ω m and suggesting the potential usefulness of polymer 13 in bistable electronics. © 2016 Wiley Periodicals, Inc.

DNase II purified from porcine spleen (pDNase II) comprises α1, α2 and β subunits. The three subunits are encoded by one cDNA, in the sequence α1, β, and α2, and the peptides linking these subunits are presumably cleaved out post‐translationally. To understand the relevance of post‐translational cleavage to pDNase II, recombinant pDNase II (rpDNase II) was produced in human 293T cells by transfection with an expression plasmid containing pDNase II cDNA (pcDNaseII). An 11.5, a 35 and a 46.5 kDa protein were detected in the cell lysates, whereas only a 46.5 kDa protein was detected in the culture medium of the pcDNaseII‐transfected cells. The 46.5 kDa rpDNase II secreted into the medium was purified to homogeneity and characterized. MALDI‐TOF MS and N‐terminal amino acid sequencing of the 46.5 kDa protein revealed a single contiguous polypeptide chain of pDNase II. Zymographic analysis showed that the 46.5 kDa protein digested DNA in acidic conditions and that the specific activity of this rpDNase II was about twice that of pDNase II purified from porcine spleen. Treatment with chloroquine, a lysosomal inhibitor, resulted in the accumulation of only the 46.5 kDa protein in the pcDNaseII‐transfected cells. Treatments with cycloheximide 22 h after transfection led to accumulation of the processed enzyme and disappearance of the 46.5 kDa protein. These results suggest that the proteolytic processing of rpDNase II occurs in the lysosome, which is not involved in the activation of pDNase II.


Carbon dioxide can be readily converted quantitatively and under mild conditions into the aryl isocyanate and symmetrical carbodiimide via a metathetical reaction involving a zwitterionic titanium imide (nacnac)Ti=NAr(CH(3)B(C(6)F(5))(3)) (nacnac(-) = [ArNC((t)Bu)](2)CH, Ar = 2,6-(i)Pr(2)C(6)H(3)). The metathetical process to generate isocyanates allows also for facile formation of sterically demanding aryl isocyanide, by a deoxygenation route. Labeling studies using enriched (13)CO(2) are also described.


Because of the typical features of the mass culture with instigation, entertainment and toadyism, people have attacked it from its beginning. Actually, mass culture is a double-edged sword, it has two sides of influence on the culture of campus. We should challenge it, analyze it and find an appropriate countermeasure to it.


Noninvasive cardiac imaging plays an important role in diagnosis and management of patients with known or suspected coronary artery disease. Traditionally, the degree of coronary artery stenosis has been evaluated by catheter coronary angiography, and the hemodynamic significance of the stenosis evaluated by a functional test, such as rest and stress myocardial perfusion scintigraphy using SPECT or PET.


BACKGROUND: The aggresome/autophagy pathway is the primary mechanism for disposal of ubiquitinated proteins for cells exposed to proteasome inhibition. Preclinical evidence shows that combining inhibition of the proteasome with bortezomib (Bz) and inhibition of autophagy with the anti-malarial drug hydroxychloroquine (HCQ) leads to enhanced cytotoxicity in myeloma cells. METHODS: Patients with relapsed or refractory myeloma are enrolling on a standard 3+3 dose escalation design. Patients receive a 2-week run-in of single-agent oral HCQ (at escalating doses), followed by addition of standard dose bortezomib (on days 1, 4, 8, and 11 of 21-day cycles). Dose-limiting toxicity (DLT) is defined as grade ≥3 toxicity probably related to study therapy and occurring during the first 5 weeks, with the exception of any anemia or lymphopenia, neutropenia responsive to growth factor, platelets >10,000/mm3 not associated with bleeding, or gastrointestinal complaints relieved by symptomatic therapy. Response is assessed on day 1 of each cycle according to International Working Group criteria. We use electron microscopy (EM) to characterize changes in autophagic vesicles (AVs) in serial samples of peripheral blood mononuclear cells (PBMCs) and CD138-selected bone marrow plasma cells (BMPCs) RESULTS: Ten patients have enrolled in the first 3 dose levels (see table). The median age is 63.5 (range 43–68), and 5 (50%) are male. The median number of prior lines of therapy is 4 (range 1–8). Seven patients had received prior Bz. No DLTs have been observed. Adverse events have generally been those expected with Bz: thrombocytopenia (30%, grade 3: 20%), anemia (70%, grade 3: 30%), and fatigue (70%, all grade 1/2), as well as neutropenia (20%, grade 3:10%). Grade 2 treatment-emergent peripheral neuropathy occurred in 1 patient (grade 1 in 3 patients). No patients developed retinal toxicity. Four patients had pulmonary infections: 1 viral influenza, 1 H. influenzae, and 2 lobar pneumonias; all resolved with appropriate antibiotics and did not preclude continued therapy. One patient died from complications of C. difficile colitis that occurred at the end of the 4th cycle, after antibiotic therapy for an upper respiratory infection. One patient had a minor response after previously progressing on single-agent Bz. EM analysis of PBMCs and BMPCs show no significant changes in AVs thus far with the lowest dose of HCQ. Enrollment is ongoing at higher doses of HCQ (escalating from 400 to 1200 mg daily). CONCLUSION: At the lowest dose levels tested, combined Bz and HCQ is tolerable, without evidence of synergistic toxicity. EM is a feasible pharmacodynamic assay for patient tumor and normal cells. Further dose escalation will determine whether combined autophagy and proteasome inhibition is achievable and safe with these agents. Updated clinical and correlative results will be presented.


We first developed an actual HVAC experimental chamber including an air distribution system, an air handling unit, fan coil units, and control systems. This experimental chamber is a real size model of a typical office and has a floor area of 61.44m. At the same time, we developed a Ò Numerical HVAC experimental chamber,Ó that is, a computer model that can simulate our actual HVAC experimental chamber including its control system. This model consists of a numerical turbulent flow model and an automatic PID control model. In this paper, we describe the actual HVAC experimental chamber, the Ò Numerical HVAC experimental chamberÓ and some results from a simulation study using the Ò Numerical HVAC experimental chamber.Ó INTRODUCTION As a result of the increasing demand for environmentally friendly buildings, changes in the design and planning of heating, ventilation and air conditioning (HVAC) systems will be needed. Conventional designs of HVAC systems are based on the capacity at the peak load with some consideration given to the temperature and air velocity distributions at the peak load. One change that is needed is a design in which fluctuating temperature distributions and HVAC performance under everyday conditions are fully considered. Another change that is needed is a rational operation and control method for the HVAC system that minimizes loss of energy and maximizes the use of renewable energy. To meet these requirements, a method that can simulate HVAC system performance and simultaneously give temperature and air velocity distributions is needed. Many HVAC experimetal chambers have been developed to investigate those complex prblems. (Bauman 1998, Brandemuehl 1996, NREL etc.) However, in order to meet such complex requirement, numerical analysis by using CFD is also an indispensable technology. In this case, verification by experiments is essentially needed to upgrade the reliability of analysis results. Further in order to apply the experimental results and CFD analysis results to practical buildings, CFD analysis should be carried out under the condition nearer to the actual by freely changing the shape of an experimental chamber, the configuration and position of air outlets, outdoor air temperature and solar radiation. We first developed an actual HVAC experimental chamber including an air distribution system, an air handling unit, fan coil units, and control systems. This experimental chamber is a real size model of a typical office and has a floor area of 61.44m. This is developed to investigate realistic behavior of indoor environment and energy consumption in offices with air conditioning systems. This chamber itself has ability to change diffuser type, type of perimeter conditioning unit, outdoor temperature and solar radiation to some extent. However there is of course a limit for the range and types of those parameters, particularly in change of dimension of the chamber and solar radiation (direction of the building). As such, we developed a Ò Numerical HVAC experimental chamberÓ on a computer, that is, a computer model that can simulate our actual HVAC experimental chamber including its control system. This model consists of a numerical turbulent flow model and an automatic PID control model. In addition, we developed a man-machine interface (MMI) program to facilitate changes in all the parameters and experimental conditions. In this paper, we describe the actual HVAC experimental chamber, the Ò Numerical HVAC experimental chamberÓ and some results from a simulation study using the Ò Numerical HVAC experimental chamber.Ó HVAC EXPERIMENTAL CHAMBER Photo-1 shows the indoor view, Figure-1 the plan and cross section, and Table-1 the major specification of the HVAC experimental chamber. The experimental facility consists of a main experimental chamber located at the center and three chambers (one for simulating outdoor conditions and two for simulating adjacent rooms) located surrounding the main experimental chamber. The main experimental chamber at the center simulates modern office space precisely employing integrated ceiling made of rock wool acoustic board, concrete with plaster board for the external wall, plaster board attached on light-weight steel partition base for the internal wall and floor panels (500mm x 500mm) of light-weight inorganic material reinforced with metal for raised floor system. The size of the chamber with


This empirical study aims to identify the influence of supply chain technology (SCT) strategies and organizational capabilities of Korean small-and medium-sized manufacturers, adopting and operating SCT strategies, on corporate performance. SCT strategy factors of small-and medium-sized manufacturers were considered independent variables, while corporate performance variables were considered dependent variables. Both exploratory factor and reliability analyses for the SCT strategy metrics were employed. Results showed that SCT strategies, the impact of technology innovation competence on corporate performance, influence of SCT strategies on corporate performance, and the mediating effects on SCT strategic factors and corporate performance were significant and adopted. Generally, these results imply that the introduction of Vendor Managed Inventory, Enterprise Resource Planning, Collaborative Planning Forecasting and Replenishment, Warehouse Management Systems, and Order Management System as SCT strategic factors are directly re-lated to enhanced corporate performance. In the context of technology innovation competence, the factors are closely linked with capabilities in strategic planning, research and development, manufacturing, and marketing. In the context of SCT strategic factors of small-and medium-sized manufacturers, if technology innovation competence is combined, enhancing corporate performance is possible.


A receding-horizon-type LQG control problem for switched linear systems is proposed and applied to the case of Markov switching. The objective is to determine a linear dynamic output feedback control law that minimizes a finite-horizon quadratic cost over all admissible future switching paths subject to almost sure uniform stability of the closed-loop system. A solution is determined by running a series of semidefinite programs offline until a saturation in achievable performance is reached.


The purpose of this study is to determine the influence of family ownership and family control on a firm's dividend policy of publicly listed firms in Indonesia and Malaysia. This study applied the generalized least square panel data over 2003-2016 and considering the period of global financial crisis 2008-2010. The results show that a firm with a higher percentage of family ownership pays more dividend compared to non-family firms. The same effect applies to the percentage of family control. In contrast, we found that higher debt levels will reduce the dividend payment. These findings indicate that dividend distribution can be used as a policy to lessen agency problems of listed firms.


The recent article "Intrapulmonary Shunt Is a Potentially Unrecognized Cause of Ischemic Stroke and Transient Ischemic Attack" (TIA) by Abushora et al. raises several questions in our daily clinical evaluation of patients with stroke, and also divers with unexplained Type II decompression sickness (DCS). A cohort of patients (stroke group) with either nonhemorrhagic stroke (CVA) or TIA (n = 321) was compared with ageand gendermatched control patients (n = 321). A subgroup of patients with CVA or TIA had what was defined as cryptogenic stroke (n = 71). These patients underwent transesophageal echocardiography, and were evaluated for visualization of saline contrast bubbles within the left atrium (LA) via either the pulmonary veins or through a patent foramen ovale (PFO). An intrapulmonary shunt was defined as direct visualization of bubbles within one or more pulmonic veins entering the LA. A PFO was defined as direct visualization of contrast crossing the foramen ovale, or visualization of contrast with the LA within three cardiac cycles of its appearance within the right atrium. Studies were performed with normal respirations, with no provocative maneuvers for detection of PFO. The authors mention that the study was performed without provocative maneuvers, to allow for a definitive differentiation between shunting via a pulmonary vein or PFO. For both detected intrapulmonary shunts and also PFOs, severity of shunting was graded based on the amount of contrast in a pulmonary vein or that entering via a PFO. Mild, intermediate, or large shunts were defined as 1–4, 5–20, or >20 visualized within any single image frame. Intrapulmonary shunts occurred more often in the stroke group than controls (72 of 321 or 22% vs. 32 of 321 or 10%). The severity of shunting was similar in both groups, mostly mild or intermediate. The number of pulmonary veins demonstrating shunting appeared to occur in 1, 2, or all 4 veins for both groups. The stroke group with detected intrapulmonary shunting did have a tendency toward contrast appearing in all 4 veins (38% incidence) more often than in controls (28%). Patent foramen ovale detection was higher (73 of 321 or 23%) for the stroke group versus controls (54 of 321 or 17%), but did not achieve statistical significance. The stroke group tended toward larger shunts compared to controls. Patent foramen ovale and/or an intrapulmonary shunt were noted more often in the stroke group (136 of 321 or 42%) than in controls (54 of 321 or 17%). The incidence of both an intrapulmonary shunt and a PFO in the same patient was not mentioned. From the stroke group a subgroup of patients was identified as having either a cryptogenic CVA (n = 50) or cryptogenic TIA (n = 21). This cryptogenic stroke group (n = 71) was then compared with an ageand gender-matched control group (n = 71). In this cohort, intrapulmonary shunting occurred more often (25 of 71 or 35%) than in controls (5 of 71 or 7%). Shunting in the cryptogenic group occurred in 1 or 2 veins 2/3 of the time and 1/4 of the time in all 4 veins, whereas in the control group, shunting occurred exclusively in 1 or 2 veins.

The invention of a lightweight panel with the trade mark Dendrolight is one of the most distinguished wood industry innovations in the last decade. At present, three-layer cellular wood panels have wide non-structural application. The aim of the research was to evaluate the compression properties of three-layer cellular wood panels for structural application. 8 specimens were manufactured for both perpendicular and parallel compression tests for each of 6 structural panel models. Scots pine cellular wood and solid pine wood ribs were used as the core layer of the structural panels. The cellular wood core was placed in a horizontal or vertical direction. Solid Scots pine wood panels and birch plywood as top layer material were used. The common stress type in subfloor and wall panels is compression, therefore the influences of the cellular material orientation, ribs and top layer material on the sandwich-type structural panel compression strength were evaluated according to LVS EN 408. 15 [LVS EN 408]. Extra parameters, such as the moisture content and apparent density, were determined. Different structural models have a great effect on the compression strength of cellular wood material panels. The highest compression strength in a parallel direction, 17.5 MPa, was achieved with a structural model with cellular material placed vertically, with the ribs and top layers of solid timber, but in a perpendicular direction, 4.48 MPa was achieved with a structural model with cellular material placed vertically and the top layers of plywood. Solid wood ribs significantly influence the compression strength when the panels are loaded in a parallel direction.


We propose several new efficient non-interactive zero knowledge (NIZK) arguments in the common reference string model. The final arguments are based on two building blocks, a more efficient version of Lipmaa's Hadamard product argument from TCC 2012, and a novel shift argument. Based on these two arguments, we speed up the recent range argument by Chaabouni, Lipmaa and Zhang (FC 2012). We also propose efficient arguments for two NP-complete problems, subset sum and decision knapsack, with constant communication, quasilinear prover's computation and linear verifier's computation.


During the early Paleogene the Earth experienced long-term global warming punctuated by several short-term 'hyperthermal' events, the most pronounced of which is the Paleocene-Eocene Thermal Maximum (PETM). During this time, tropical climates expanded into extra-tropical areas potentially forming a wide band of 'paratropical' forests that are hypothesized to have expanded into the mid-latitude Northern Great Plains (NGP). Relatively little is known about these 'paratropical' floras, which would have extended across the Gulf Coastal Plain (GCP). This study assesses the preserved floras from the GCP in Central Texas before and after the PETM to define plant ecosystem changes associated with the hyperthermal event in this region. These floras suggest a high turnover rate, change in plant community composition, and uniform plant communities across the GCP at the Paleocene-Eocene boundary. Paleoecology and paleoclimate estimates from Central Texas PETM floras suggest a warm and wet environment, indicative of tropical seasonal forest to tropical rainforest biomes. Fossil evidence from the GCP combined with data from the NGP and modern tropics suggest that warming during the PETM helped create a 'paratropical belt' that extended into the mid-latitudes. Evaluating the response of plant communities to rapid global warming is important for understanding and preparing for current and future global warming and climate change.


Objective To compare the efficacy of atenolol and diltiazem SR in the treatment of silent myocardial ischemia (SMI) and hypertension Methods Seventy three patients with mild to moderate hypertension and SMI were randomly allocated to be treated by atenolol 25 mg/d (group A, n =37) or diltiazem SR 90 mg/d (group D, n =36) for eight weeks The changes of heart rate, office blood pressure(OBP), ambulatory blood pressure(ABP) and SMI during 48 hour ambulatory electrocardiography were compared before and eight weeks after treatment Results OBP and ABP were lower under both regimes During 48 hour ambulatory electrocardiography, the frequency of ischemic episodes decreased by 59 9% with atenolol, 86 6% with diltiazem SR Total ischemic duration decreased by 44 9% with atenolol, 84 7% with diltiazem SR Side effects were 21 6% in group A and 11 1% in group D, respectively Conclusion Diltiazem SR is more effective and better tolerated in the treatment of the silent myocardial ischemia and hypertension


Objective: To evaluate the association of prostate volume with post micturition residual urinary volume (PMR) in benign prostate hyperplasia (BPH).Methods: This was cross-sectional analytical study with sample size of 100, performed at Gilani Ultrasound Centre, for six months. Study was performed in Gilani Ultrasound Centre, Lahore, from 15-5-2017 to 16-11-2017.  Individuals of age 40-80 years diagnosed for BPH were included. The patients who had prostate cancer, who had undergone minor urinary tract or prostate surgery, patient with UTI or bladder stone were not considered in this research. Transabdominal sonography was performed with convex transducer of 3.5 - 5MHz frequency. Outcome variables were Prostate volume and post micturition residual (PMR) volume.Results: Hundred BPH positive individuals were recruited in this study. The results were gathered which showed that the association between prostate volume and post void residual volume was not significant.Conclusion: There was no significant correlation between BPH and PMR, rather bladder outlet obstruction could be caused by the enlargement and protrusion of median lobe of prostate.


The paper considers one of the most important state functions as the judicial acts compulsory execution in the context of the consistent law-enforcement procedure, the judicial remedy of individuals and corporate entities. It's defined the notion of compulsory execution organization, and also sustained the proposition that in Russia this law-enforcement function is the prerogative right of the state.


Under flow energy dissipation takes some engineering measures to control water jump position in,and to eliminate residual energy by the water jump surface roller and strong turbulence. Comprehensive energy dissipation pool is a cost-economy energy dissipation pool due to lower apron elevation and building not too high energy dissipation obstacle. The previous studies on the conjugation water depth and the length of free hydraulic jump for a gradually expanding stilling basin were analyzed. The height of obstacle at the end of a gradually expanding flat-bottom stilling basin was calculated by different calculation methods. The comparative analysis of calculation results shows that the method using energy equation is more appropriate,and that the calculation result of the height of obstacle by the method using momentum equation is 33. 5% smaller than that by the method using energy equation. Finally,the factor causing the calculation value of obstacle height too small was analyzed,and the calculation method using energy equation is suggested.


Desdobramentos do contínuo is a work for violoncello and live electronics written in 2016. It was the last live electroacoustic music composed during Rossetti's Ph.D. thesis [1], defended in the same year. The work was composed in collaboration with the violoncellist William Teixeira, for whom it is dedicated. In terms of structuration, the piece involves two types of electroacoustic procedures, in addition to the instrumental writing of the score. Among the electroacoustic procedures, there are tape sounds, precomposed in a studio in deferred time [2] and real-time treatments applied to the violoncello sound captured live. For the composition of the deferred time sounds (tapes), time-frequency analysis procedures of phase vocoder [3] and convolution [4] were employed. From them, pitch-shifting and time-stretching processes could be implemented. Both of these procedures were performed having violoncello recordings as source material. For the real-time processing, which was implemented in Max MSP, objects of HOA (High Order Ambisonics) Library – developed by the CICM (Centre de recherche Informatique et Création Musicale) of Université Paris 8 – were used. Employing the process object belonging to this library it is possible to combine electroacoustic treatments such as granulation, convolution, dephasing and microtemporal decorrelation (among others), with a high order ambisonics spatialization [5]. From a morphologic standpoint, the composed tape sounds have a continuous development in time, while the real-time generated sounds (mainly produced by a granulation process) have a discontinuous structure. The motivation for this composition comes from an interpretation of René Thom's Catastrophe Theory [6], explained by him as a methodology that allows the organization of experience information in various conditions. Thom searched to describe discontinuities observed in a system evolution. He assumed that a system is presented as a succession of continuous evolutions, separated by abrupt leaps of qualitatively different natures. We imagine the morphology of the whole piece as a continuity formed by, in its interior, continuous and discontinuous instrumental and electroacoustic sounds which are overlapped. This superposition of different sounds produces the timbre of the piece that can be perceived as one unity of form. The objective of combining and overlapping deferred time sounds and real-time electroacoustic treatments to the violoncello acoustical sound is to create different layers that would merge together into a single structure. Our hypothesis in relation to both electroacoustic sounds (represented by continuous and discontinuous structures) is that this overlapping would be complementary and permeable in terms of sound morphology, generating a single perceived timbre. In relation to the dialogue between instrumental and electroacoustic sounds, concepts of interaction and convergence [7] were addressed. Interaction is defined as a kind of action that occurs as two or more objects have an effect one upon another, where the idea of a two-way effect is essential. Convergence can be explained as the movement towards union or uniformity, the independent development of similar characters associated with similarity of an environment, and the merging of distinct technologies or devices into SBCM 2017 16th Brazilian Symposium on Computer Music


We found that currents flowed across an interface, when a nitrobenzene solution containing fullerene, C 60 , and tetraoctylammonium tetraphenylborate was illuminated. Expecting that a photochemical reaction of C 60 would be responsible for the currents, we investigated its mechanism. Voltammetric and spectroscopic experiments suggested that the currents were generated through ion transfer of anions produced during the photochemical reaction and/or electron transfer between anion radical of C 60 and oxygen. Further, we propose a galvanic cell based on the photochemical reaction.


The article is about military struggle in Terek in 1918. It was the longest revolt in the beginning of the Civil War (from June to November 1918) and showed strong anti-Bolshevist moods in the region. It also blocked considerable amount of "the Reds" on the Nothern Caucasus during the decisive battles for the region on Kuban and Stavropol.


ABSTRACT Considering that the definitions of politics which dominate political economy are actually synonyms for other terms (politicians, powering or strategising), and in order to focus research more sharply upon the political itself, this article proposes a robust alternative: politics as the mobilisation of values to change or reproduce the institutions that orientate economic activity. Drawing upon constructivist strands of institutionalism, political sociology and industrial economics, this definition is used to build an analytical framework for understanding the 'political work' which determines the policies of both firms and public regulatory authorities. Specifically, using this 'politics as values approach', a fundamental tension within capitalism between the values of Freedom, Security and Equality is closely examined. This is tackled by studying conflicts within the definition of these three values during the regulation of specific industries, together with their prioritisation. To illustrate the heuristics of this analytical framework, the case of recent change within the regulation of medicines in France is then developed. Far from simply resulting from a drug 'scandal', this approach shows that this change was caused firstly by a value-driven conflict within pharmacology and, secondly, by its impacts upon the way administrators, journalists and politicians have reframed the Freedom–Security–Equality value hierarchy.


The number of icosahedral-capsid structures determined at a near-atomic level of resolution is growing rapidly as advances in synchrotron radiation sources, fast-readout detectors, and computer hardware and software are made. Hence, there is an increasing need to organize these mega-assemblies into a uniform and easy-to-use database. The coordinates of the icosahedral-capsid structures deposited in the Protein Data Bank (PDB) (2) follow a variety of conventions in which the icosahedral symmetry axes are oriented differently in the orthogonal coordinate system. While trying to analyze the various capsid structures en masse, we became aware of the need for a database in which all capsid structures (coordinates) are stored in a standard icosahedral orientation. Such a structural database of viral capsids would indeed facilitate the development of tools for high-throughput analyses of the virus structures. We report here the creation of a web-base (website and database) of virus structures, the Virus Particle Explorer (VIPER), which can be accessed through the World Wide Web (WWW) at the uniform resource locator (URL) http://mmtsb.scripps.edu /viper/. The organization of the VIPER database is shown in Fig. Fig.1.1.

Objective: To observe the changes and the characteristics of phrenic nerves under a certain freezing temperature and to further explore the relationship between the freezing time and the nerve injury and repair so as to determine the safety of phrenic nerve cryotherapy.Methods: The goats were used as experiment animals and the temperature of cryotherapy device was enacted as-65 ℃.The right thorax was opened through the eighth intercostal incision to make the phrenic nerves free on the lateral surface of inferior vena cava and perform the phrenic nerve cryotherapy of 30,60,90 and 120 seconds respectively.The right thorax was opened again after 60 days of the operation to perform the phrenic nerve cryotherapy at the different time and choose the materials then to carry out the pathology examination.Results: The clear nerve degeneration and the nerve fiber fracture on the operative days were shown in the 90 and 120 seconds groups.The freezing nerves in 30 and 60 seconds groups,however,presented a little edema of the neurilemmas,axons and myelin sheaths.Specimens after 60 days of the operation had no obvious differentiation between the nerves observed with naked eyes at different freezing time and the normal phrenic nerves.All of the nerves became normal under the microscope,but there still were some hyperplasia changes.Conclusion: The damage of phrenic nerves under-65 ℃ progresses severely along with the prolonging of the freezing time.The freezing nerves present damage obviously above 90 seconds.It proved that the phrenic nerve cryotherapy is safe because the freezing nerves of 120 seconds could still be repaired.


There has been made an assumption, correlating with experimental data, that the phenomenon of effectively chiral-pure, chiral-induced spiralization of macromolecules in weakly polarized heterochiral solutions is determined by the mechanism of physico-chemical annihilation: enantiomers-antipodes of a chiral compound in a heterochiral solution annihilate; that is, they form achiral dimers, the solution becomes effectively homochiral and further, chiral-induced macromolecular spiralization of one sign of helicity is realized in it in the same way as in other homochiral solutions.


Meta-cognitive learning strategy is the essential learning strategy for second language learning, and students who have good meta-cognitive learning strategy, who is better at second language learning. For Chinese students, second language vocabulary learning is very important and quite difficult. This paper mainly uses confirmatory research to investigate the influence of meta-cognitive learning strategies on the individual at the aspect of second language vocabulary learning and proposes further suggestion to the second language teaching.


In this paper, we build a Bayesian vector auto regression model( BVAR) and a Markova regime switching vector auto regression model( MS-BVAR). Through these models, we study if there are the regime switching effect in Chinese economy and the characteristics of the monetary policy in different regimes based on the core inflation perspective. The results show that: 1) The regime switching model is more suitable for Chinese economic characteristics, so Chinese economy presents district system division; 2) There is the large persistence of the core inflation in different regimes, the average duration of the high inflation regime is 66 months and the average duration of the low inflation regime is 59 months. The innovation of this paper is that we study the characters of the regime switching of economy and the monetary policy from the core inflation perspective, estimate the core inflation, exclude the short volatility factor of the inflation and can obviously represent the trend character of the inflation.


Basal stem rot (BSR) which is caused by Ganoderma boninense is the most serious disease faced by oil palm Elaeis guineensis in Malaysia. Hitherto, many control measures such as cultural practices, fungicides, and biocontrol agents were attempted, yet, the result were unsatisfactory. This study was conducted to investigate potential antimicrobial properties in oil palm leaf extract against G. boninense. Oil palm leaf were extracted with different solvents namely methanol, acetone, chloroform and petroleum ether. The antimicrobial activities and fungitoxicity of leaf extracts against G. boninense were expressed in inhibition of mycelia growth of G. boninense on Potato Dextrose Agar (PDA) incorporated with the four different solvent leaf extracts with range concentration of 0-40 mg mL -1 . Acetone leaf extract was found to be very fungitoxic to G. boninense at concentration of 40 mg mL -1 , the highest concentration tested in this study. Methanol and petroleum ether leaf extracts were having inhibitory effect with 40 mg mL -1 in comparison to the absolute control. Further separation of active bioactive compounds was conducted using thin layer chromatography (TLC) bioassay for methanol and acetone leaf extracts. Acetone extract was found to possess good antifungal activity with properties of Rf 0.09, 0.21, 0.24, and 0.60 compared to methanol extract, which only showed inhibition at Rf0.74 against Aspergillus niger. The Rf values suggested that potential antimicrobial compound might be mixtures of polar and non-polar properties. The results suggested oil palm leaf extract might potentially explore as an important allelopathic agent against Ganoderma boninense.


In order to compare the effects of loss control fertilizer (WC) and normal compound fertilizer (NC) on the nutrition accumulation and yield of wheat, a random block experiment was set at the experimental field of Baoding Academy of Agricultural Science during 2015-2016. The winter wheat variety of Baomai 10 was used as material. Two kinds of fertilizers with the same nutrition content of 20%N, 20%P2O5 and 8%K2O were used and the application rate of fertilizers was 600 kg/hm, applied once with soil preparation before sowing, 3 reps. The results showed that there were significant differences on dry matter accumulation, nutrition accumulation and yield characteristics with different fertilizer treatments, and the effect of WC treatment was significantly better than that of NC. Compared with NC, the 1 000-grain weight, dry matter and yield of wheat of WC could be increased by 2.5%, 11.0%, 6.3%, respectively. The accumulation amount of N, P, K of wheat plants at different growing stages were shown as follows: WC>NC>CK. The fertilizer agronomic efficiency (AE) was increased by 23.5%, compared with that of the NC treatment. At the same time, the nutrition amount in the top soil was also increased. As a new type of fertilizer, WC will play an important role in improving the yield of wheat, increasing the efficiency of 基金项目:安徽铜陵六国化工资助项目(2015) 作者简介:田金柱(1965—),男,高级农艺师,主要研究方向:农业推广 通信联系人:张凤路,教授,主要研究方向:作物栽培生理.

Fawcett (1990) has thrown down the gauntlet to behavior analysts, "Our challenge is to discover standards that optimize both rigor and relevance in the pursuit of understanding and action" (p. 65). For decades, behavior analysts have been working explicitly to develop a behavior-change technology to advance an array of dassroom competencies for students of all ages and ability levels (Sulzer-Azaroff, 1986). With precision, rigor, and results as their hallmark, behavior analysts have documented, in literally hundreds of investigations and numerous specialty journals, the scope and effectiveness of their behavioral technology. However, there is now widespread recognition that these outstanding achievements are being virtually ignored by teachers (Axelrod, Moyer, & Berry, 1990). In effect, the relevance of these rigorous methods is being seriously questioned by many educators. The fact is that many behavior-change interventions have been developed to improve the education process but few have been chosen (Sulzer-Azaroff, 1986). Some researchers have attempted to account for this phenomenon by asserting that teachers view behavioral technology as unacceptable because of possible misconceptions conveyed by the media and by attempts of editors to extiude behavioral findings from educational journals and texts (Greer, 1982, 1983). Others daim that it is our technical language that limits widespread use (Bailey, 1991; Lindsley, 1991). Still others have raised questions about the overall social validity of the technology and the generalization of treatment effects (Yeaton, 1982). These challenges question the social significance and relevancy of the changes produced, the durability of changes across time, the likelihood of


Leukemia stem cells (LSC) are responsible for the occurrence, therapeutic resistance, and relapse of leukemia. LSC are typically found in a dormant state and thus are less likely to respond to standard chemotherapeutic agents, which preferentially eradicate actively cycling cells and can have significant toxicity to normal hematopoietic cells. Identifying agents that target both LSC and leukemia cells is thus an important step in the development of novel therapies for leukemia. Despite the uncertainty over the phenotype, biological properties, and hierarchical organization of B-cell acute lymphoblastic leukemia (B-ALL) LSC, CD34 and CD19 together are robust markers for B-ALL LSC. Notably, these LSC have been shown to occur more frequently in high-risk B-ALL than in other hematopoietic malignancies, making it more difficult to target them. An in vitro study indicated that Tenovin-6 induces apoptosis in B-ALL cells and eliminates CD133 B-ALL LSC. LSC of patient-derived ALL are sensitive to TNF-related apoptosis inducing ligand (TRAIL), and the sensitivity of B-ALL LSC to recombinant human CD19L-sTRAIL is greater. Nevertheless, attempts at targeting B-ALL LSC or precursor cells have been limited compared to efforts combating acute myeloid leukemia stem cells. Recent immunotherapies


The vulnerability of a flight instruction system is understood as a state of affairs, processes or phenomena in the organization's internal life that diminishes its ability to react to existing or potential changes. Starting from the results of previous research conducted by the authors, the article aims to highlight the need for new ways to train Air Force pilots and suggests possible solutions. The purpose of this study is thus to identify the areas of vulnerability proper to the organization providing the training by synthesizing survey results based on the subjects' professional experience. Accordingly, we deemed necessary and at the same time pertinent to consider the opinions of the staff involved in the practical training process. For this reason, the evaluation carried out between June and July 2018 involved the Aviation Training Group at "Aurel Vlaicu" Air Force Base.


mon sense about how to execute a job; some want every detail covered; and, of course, there are many who expect just the opposite. The more we look at the principalship, the more apparent it becomes that the job is extremely complex, and listing expectations is next to an impossibility. One hundred superintendents could easily develop a rather diverse list of what they expect their principals to achieve. Presenting a group of articles on this subject is difficult. We believe, however, that principals will find the collection of articles in this Bulletin helpful as they attempt to assess their performance.


The aim of this work was to design and develop an identification device for droplet detachments during pulsed GMAW and to assess the possibility of implementing a metal transfer control system. The developed identification device was based on a luminescence sensor and on an electronic interface, capable of sensing the arc light flux. A basic control system for the pulse parameters was implemented using an A/D – D/A board for receiving signals from the sensor and sending instructions to an electronic power source and a trained neural network for the metal transfer recognition. Alternatively, the signal from the electronic interface could be directed to a microcomputer with a dedicated monitoring program. Automated pulsed welding was carried out on plain aluminum plates in the flat position. The metal transfers were recorded using a high-speed camera, applying the shadowgraphy technique, to validate the device performance. The voltage and current welding signals, as well as the optical sensor and camera signals, were synchronized to guarantee suitable analysis. The results showed that the detachment device was efficient and consistent for aluminum welding. Moreover, the control system was capable of setting parameters that provided stable transfer at One Drop per Pulse (ODPP) rate, from welds starting at inadequate pulse parameter levels. Thus, it is possible to assert that this low cost developed device is a high flexibility tool, which can be applied in optimization of pulsed GMAW, through manual or automated parameters settings, without employing a high-speed camera.


Optical photobleaching experiments were used to directly measure the molecular mobility of PMMA during creep and recovery to study the interaction between mechanical deformation and physical aging. Experiments were performed both on PMMA glasses with different aging histories at Tg − 14 K and on PMMA melts aged to equilibrium as much as 6 K below the conventional DSC Tg. Our results show that plastic deformation increases the mobility of a polymer glass, makes the system more dynamically homogeneous, and erases the predeformation aging history. After removing the stress, the highly mobile and dynamically homogeneous system quickly relaxes to a dynamically heterogeneous system. After this initial transient, glasses produced by plastic deformation follow the same aging trajectory of the thermally quenched glasses unless the strain is very large. In contrast, deformation in the preflow regime transiently increases the molecular mobility of polymer glasses but this enhanced mobility quickly returns to the ori...


Luo Longji adopted the standard of function to expatiate the relationship between human rights and the state,and between human rights and law,to point out that human rights has the spatio-temporal characteristics referring different time and different countries.Based upon this,he constructed the theoretical system of human rights to explain that human rights,under the rule of Kuomintang,was the rights which people strived for.Further he commented on and exposited his human rights theory.


The traditional view on price determination focuses on the role of monetary policy and the role of fiscal policy is usually neglected. Most analyses assume that the monetary authority is expected to set its control variable without facing any constraint, so that prices are determined by money supply and demand in a traditional way. Hovewer, a new approach has emerged in the 1990s, which allows fiscal policy to set primary surpluses to follow an arbitrary process, not necessarily compatible with solvency. "This theory could be of particular interest for monetary unions since it might contribute to explain the different evolution of the price level across the member countries. The aim of this paper is to test empirically by using panel data analysis whether the impact of the fiscal policy affects price level determination in both Old and New members and Candidate countries to the European Monetary Union. The panel data analysis basically evidences Ricardian or monetary dominant regime in all the groups.

We investigated transcriptional control of gene expression in human abdominal aortic aneurysm (AAA). We previously identified 3274 differentially expressed genes in human AAA tissue compared to non-aneurysmal controls. Four expressed transcription factors (ELF1, ETS2, STAT5 and RUNX1) were selected for genome-wide chromatin immunoprecipitation. Transcription factor binding was enriched in 4760 distinct genes (FDR < 0.05), of which 713 were differentially expressed in AAA. Functional classification using Gene Ontology (GO), KEGG, and Network Analysis revealed enrichment in several biological processes including "leukocyte migration" (FDR = 3.09 × 10−05) and "intracellular protein kinase cascade" (FDR = 6.48 × 10−05). In the control aorta, the most significant GO categories differed from those in the AAA samples and included "cytoskeleton organization" (FDR = 1.24 × 10−06) and "small GTPase mediated signal transduction" (FDR = 1.24 × 10−06). Genes up-regulated in AAA tissue showed a highly significant enrichment for GO categories "leukocyte migration" (FDR = 1.62 × 10−11), "activation of immune response" (FDR = 8.44 × 10−11), "T cell activation" (FDR = 4.14 × 10−10) and "regulation of lymphocyte activation" (FDR = 2.45 × 10−09), whereas the down-regulated genes were enriched in GO categories "cytoskeleton organization" (FDR = 7.84 × 10−05), "muscle cell development" (FDR = 1.00 × 10−04), and "organ morphogenesis" (FDR = 3.00 × 10−04). Quantitative PCR assays confirmed a sub-set of the transcription factor binding sites including those in MTMR11, DUSP10, ITGAM, MARCH1, HDAC8, MMP14, MAGI1, THBD and SPOCK1.


The American Academy of Sleep Medicine (AASM) recommends that hypopneas be identified using a definition that is based on a ≥30% decrease in airflow associated with a ≥3% reduction in the oxygen saturation or an arousal (H3A) for diagnosis of obstructive sleep apnea (OSA) in adults. This conflicts with the Centers for Medicare and Medicaid Services (CMS) definition, which requires a ≥4% decrease in the oxygen saturation to identify a hypopnea (H4) and does not acknowledge arousals. In 2018, the AASM board of directors constituted a Hypopnea Scoring Rule Task Force (HSRTF) with a mandate to "create a strategy for adoption and implementation of the AASM recommended adult hypopnea scoring criteria among members, payers and device manufacturers." The task force initiated several activities including a survey of AASM accredited laboratories and discussions with polysomnography software vendors. Survey results indicated that most laboratories scored polysomnograms using only the CMS definition. Vendors indicated that they could easily support dual scoring. Informal testing among task force members' laboratories confirmed there would be little additional work if dual scoring was performed. The task force convened several meetings of a working group of OSA content experts and interested parties, with the purpose of creating research recommendations to study the impact on relevant clinical outcomes using the different definitions of hypopnea. Several possible prospective and retrospective approaches were discussed with emphasis on the group of patients diagnosed with OSA based on an apnea-hypopnea index (AHI) using H3A but NOT H4. Based on the deliberations of the working group, the HSRTF submitted recommendations to the AASM Foundation concerning research project strategies for potential grant funding. Further discussions within the HSRTF focused on developing advocacy initiatives among patient stakeholder groups to change payer policy.


Sialyl‐Tn, Tn and T antigens are caused by aberrant or incomplete glycosylation of apomucins and are related to the aggressiveness of malignant neoplasms. Using 41 liver samples from patients with cholangiocarcinoma (including four with cirrhosis), 21 with combined hepatocellular– cholangiocellular carcinoma and 17 with hepatocellular carcinoma, the expression of sialyl‐Tn, Tn and T antigens were characterized immunohistochemically and the correlation with apomucin profiles was evaluated. The prevalence of sialyl‐Tn, Tn and T antigens expression was 89, 95 and 51% in cholangiocarcinoma without cirrhosis; 25, 75, and 0% in cholangiocarcinoma with cirrho‐ sis; 29, 90, and 48% in combined hepatocellular– cholangiocellular carcinoma; and 0, 12 and 6% in hepatocellular carcinoma, respectively. Sialyl‐Tn antigen was frequently expressed in cholangiocarcinoma without cirrhosis compared with cholangiocarcinoma with cirrhosis and combined hepatocellular–cholangiocellular carcinoma (P< 0.01). Although sialyl‐Tn expression was associated with MUC1, MUC6 and MUC7 expression, the expression sites among them were not identical in the individual cases. These data suggest that the different expressions of sialyl‐Tn antigen among cholangiocarcinoma without cirrhosis, cholangiocarcinoma with cirrhosis and combined hepatocellular–cholangiocellular carcinoma may reflect the biological features inherent to these tumors, such as the ability of invasion.


Formal verification is a technique for ensuring the correctness of systems. This work focuses on verifying a model of the Automated Teller Machine (ATM) system against some specifications. We construct the model as a state transition diagram that is suitable for verification. The specifications are expressed as Linear Temporal Logic (LTL) formulas. We use Simple Promela Interpreter (SPIN) model checker to check whether the model satisfies the formula. This model checker accepts models written in Process Meta Language (PROMELA), and its specifications are specified in LTL formulas.


New shock wave data on {100} oriented single crystal periclase covering the pressure range from 160 to 200 GPa suggest that MgO is described by a single Hugoniot up to 200 GPa, with no displacive phase transitions of volume change greater than 1-1.5 per cent. For a third order finite strain fit, with K_0 constrained to its ultrasonically determined value of 162.7 GPa, the implied K_0′ of 4.27 ± 0.24 is in agreement with ultrasonically determined value of 4.17 ± 0.14. The new data indicate a somewhat steeper Hugoniot than that suggested by previously published shock wave results under 120 GPa. A previously published result at 258 GPa shows more compression in the light of the present data than would be expected for MgO in the B1 structure, and may signal the onset of a phase transition, although we cannot confidently make this interpretation. If MgO forms an ideal solid solution with FeO, our data does not support the occurrence of a significant transition in magnesiowustite at lower mantle pressures.


In this paper we study the effect of a spatial modulation in the magnetic field on invariants such as the magnetic moment μ=V⊥2/B. In particular, we investigate whether an invariant still exists when the wavelength of the modulation is comparable to the gyro radius of the particle. In an axially symmetric magnetic field, with a square‐wave modulation, the orbit equations reduce to algebraic relations convenient for numerical study. We find from such studies that orbits are of two types: (a) regular orbits which generate an invariant; (b) orbits which are quasi‐ergodic. We have also calculated an invariant by perturbation theory with the depth of modulation of the field as a small parameter. For this we developed a modified form of perturbation theory which overcomes the difficulty of infinities arising at resonance between the perturbation and the cyclotron period. This difficulty in fact corresponds to a change in topology of the invariant curves. The invariant calculated from this theory shows very good...


An accurate and precise ultra-high performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) method was validated for the analysis of glyphosate and its main transformation product (aminomethylphosphonic acid) in barley, malt, wheat, oats, and lentils. The validation data demonstrated good performance of the method. This UHPLC-MS/MS method was also used to evaluate the performance of a commercially available enzyme-linked immunosorbent assay (ELISA) test kit. For all of the grain matrices examined, the ELISA showed poor accuracy and precision at its stated lower working limit of 0.075 mg/kg; however, performance was acceptable at 0.30 mg/kg, as well as higher concentrations relevant to established maximum residue limits. At these relevant concentrations, the ELISA also produced results higher than the UHPLC-MS/MS method. Although results from the two methods were linearly correlated, differences in the result values from the two methods differed among the grains studied and ranged from...


The sleep/wake rhythm is one of the most important biological rhythms. Quality and duration of sleep change during lifetime. The aim of our study was to determine differences in sleep efficiency, movement, and fragmentation during sleep period between genders and according to age. Sleep period was monitored by wrist actigraphy under home-based conditions. Seventy-four healthy participants—47 women and 27 men participated in the study. The participants were divided by age into groups younger than 40 years and 40 years and older. Women showed lower sleep fragmentation and mobility during sleep compared to men. Younger women showed a higher actual sleep and sleep efficiency compared to older women and younger men. Younger men compared to older men had a significantly lower actual sleep, lower sleep efficiency and significantly more sleep and wake bouts. Our results confirmed differences in sleep parameters between genders and according to age. The best sleep quality was detected in young women, but gender differences were not apparent in elderly participants, suggesting the impact of sex hormones on sleep.


The textiles capable of cutting resistance found applications in the industrial and military areas to construct flexible lightweight soft body armors. In the present work, a theoretical model to understand the mechanism of fabric cut resistance in a different direction for weft-knitted, triaxial, and multiple layers structures. An experimental study of cutting resistance force was done on weft-knitted fabric with Kevlar 29 triaxial fabrics in multiple layers structure to support derived mathematical model for the effect of multiple layers structure on their cutting force. The study examines specific cut resistance of the structure from four layers of Kevlar triaxial fabrics covered with knitted fabric on both sides. The angle of cutting force varied from 0°, 60°, and 90° with respect to the yarn inclination. Results show that the cutting force of the multilayer structure is linearly proportional to the number of Kevlar triaxial fabrics layers. The specific cut resistance value of the structure from four layers of Kevlar triaxial fabrics, covered with knitted fabric on both sides, reached 544, 435, and 326 (N/g/cm2) for cutting directions: angled 60°, vertical, and horizontal, respectively. In this work, the comparison between the triaxial fabric of high areal density and multiple layers of triaxial fabric with resultant same areal density indicates that a better specific cutting force was achieved in the first case. Furthermore, it investigated the relationship between triaxial surface density, the direction of cutting, and the number of triaxial fabric layers and discussed the optimum specific properties of the different structures.


A modified electrode was developed by immobilizing horseradish peroxidase(HRP) onto a biocompatible glassy carbon electrode(GCE) modified with a DNA/poly(ferrocenylsilane)(PFS)/room temperature ionic liquid(RTIL) film and the as-prepared GCE/DNA/PFS/RTIL/HRP electrode provides both a biocompatible microenvironment for HRP to keep its good bioactivity and an effective pathway of electron transfer between the redox center of HRP and the electrode surface.The modified electrode showed a good electrocatalytic behavior toward the reduction of H2O2.The electrocatalytic behaviors of GCE/DNA/PFS/RTIL/HRP to the reduction of H2O2 were investigated by cyclic voltammograms and amperometric technique in detail.Under the optimized conditions,the modified electrode shows fast response to the electrocatalytic oxidation of H2O2 and the steady current was observed within 2 s.The catalytic current is linear to the H2O2 concentration in the range of 3.25 μmol/L to 1.47 mmol/L and 1.86 mmol/L to 5.35 mmol/L.The detection limit was 0.86 μmol/L based on the criterion of a signal-to-noise ratio of 3.The biosensor showed high sensitivity,good reproducibility and stability.Furthermore,the modified electrode also showed a good electrocatalytic behavior toward the reduction of O2.

"China Dream"is not only a dream of national rejuvenation,but also a dream for all countries in the world to realize winwin cooperation. Although the deep development of globalization provides a vast international arena for the realization of China Dream,the national rejuvenation is still facing many difficulties from the outer world in the process of globalization dominated by western developed countries. To cast "China Dream"in the condition of win-win cooperation,China must learn experiences and lessons from other countries,make great efforts to create a peaceful and stable diplomacy environment,be actively an important participant and shaper in international rules,seek the advantages in the win-win cooperation and competition and enhance the soft power of Chinese culture in international communication.


The characterization of the conventional and organic cotton fibres to understand the differences present between them is presented. The cotton fibres were characterized for their fibre properties such as the surface morphology, surface chemical composition, surface elemental composition and internal fibre structure. The results show that the surface morphology and surface chemical composition of both the cotton fibres are similar. The surface elemental composition of both the cotton fibres shows that organic cotton fibres have higher percentage of metals than the conventional cotton fibres. Based on the FTIR spectrum analysis, it is observed that the organic cotton fibres may have a higher proportion of representative groups compared to that of the conventional cotton fibres. The fraction of I α and I β cellulose shows that I β cellulose dominates in both cotton fibres. The crystallinity of both the cotton fibres was determined using the wide angle X-ray diffraction data. The results show that crystallinity of both fibres is similar.

In this paper we study the linear quadratic optimal control problem for linear hybrid systems in which transitions between different discrete locations occur autonomously when the continuous state intersects given switching surfaces. In particular, we make an explicit connection between the newly developed, Pontryagin-type Hybrid Maximum Principle and the Bellman Dynamic Programming approach. As a consequence, we extend the classic Riccati-formalism, derive the associated Riccati-type equations, and prove the discontinuity of the full "hybrid" Riccati matrix. Finally, we discuss some computational aspects of the obtained theoretical results and propose a numerical algorithm in the framework of an optimal feedback control law.

Abstract The involvement of  women in public area is not a new phenomenon, because for along time women not only do their role in domestic area. But their involvement in public area unequal with their quantity and their opportunity to achieve strategic official like men. In fact, it does not easy for women to achieve strategic position with their capacities. Practical of  politics and government point out that women involvement in thus area just being as a normative assurance. In empirical condition it is too hard for women for being official because of internal factor  like  unconfident with their abilities and skills. Commonly  women also  believe that they do work just assist their husband and develop career is  a second choices. But the dominant factor are  cultural patriachi that influence mindset which is believe that women shouldn't doing competition with men for getting official.  There  is also political penetration as a constraint  which is women having less opportunity and believe that politics is full of dirty  and it's not good for women. All of those reasons contribute that gender quality is still hard to be realitation, include in Semarang City, although gender quality is a human right and advancing gender quality is being UN and a global commitment. Keywords : Domestic Area; Gender Quality; Culture Patriachi

Abstract On December 2019, in Wuhan-China, SARS-Cov2 coronavirus emerged, causing the COVID-19 pandemic, responsible by June 29 2020, for 10.112.754 cases, and 501.562 deaths, in over 213 countries. Our research aims to study the impact of COVID-19 on Facebook and Instagram posting activity, regarding publications with word 'Coronavirus', their total interaction and source, as well as an analysis of possible fake news A sample of 4.000 posts (3.025 Facebook and 975 Instagram posts) was extracted through a web-based social media analytics tool, over two periods: January 10-February 27 (P1) and 01 May-June 28 (P2). Data were analysed using Microsoft tools. The 2.000 P1 posts generated 77.654.161 interactions - 70% likes, 4% comments and 27% shares. However, the 2.000 P2 posts prompted more than four times engagement, with 330.930.859 interactions - 92% likes, 2% comments and 6% shares. From January to February, likes increased 59%, but comments and shares decreased by 27% and 57%, respectively: users are generally more engaged but at a less profound level. From May to June, likes, comments and shares decreased 41%, 43% and 51%, as users gradually come out of confinement. Certain events boosted engagement: on January 21, as the first case in the United States was announced, 767.280 interactions were reported, a 21-fold increase from the previous day; February 16 was the day with more monthly engagement when the first case in France was announced. January 25, CNN posted the Facebook post with more interactions of the month (2.510.695). On February, the post with most interactions was from Real Madrid Football Club. On P2, the two most popular posts were from The United Nations International Children's Fund Facebook page (May post had 4.153.981 interactions).

To explore the blast-resistant mechanisms of large-scale multilayered thin plates subjected to close-range explosions of warheads, finite element simulations as well as model tests were carried out. Blast loads, deformation processes, strain distributions and deformation energy absorptions of the clamped multilayered square plates under close-range air blast loads were numerically analyzed. Comparisons between multilayered plates and single-layer plates of the same materials and equal total thicknesses were conducted.On the basis of the numerical analysises, further investigations into the influences of interlayer spaces, layer numbers and boundary conditions on the blast resistances of multilayered plates were performed. The results show that under model test conditions, multilayered plates absorb more deformation energy than their monolithic counterparts, whereas their maximum strains are smaller, and strain distributions are more uniformly than those of the monolithic counterparts. Under ultimate strain conditions, a significant enhancement in deformation energy absorptions is obtained for multilayered plates comparing with their monolithic counterparts. Appropriate increase of interlayer spaces leads to a certain extent enhancement in deformation capabilities for multilayered plates, while overlarge interlayer spaces are unfavourable to their overall harmonious deformations. Deformation capabilities of multilayered plates are improved by increasing layer numbers. Comparing with clamped boundary conditions, simple-support boundary conditions are more conductive to the adequate exertion of deformation-energy-absorbing capabilities for multilayered plates.


Background: Stroke rates and risk factors may be increasing in young adults aged 18-64, especially black individuals. We sought to identify whether young high risk stroke survivors could be found at community health centers. Methods: This was a cross-sectional analysis of the National Ambulatory Medical Care Survey from 2006-2011. We used chi-square analyses, t-tests, and proportions to compare and describe stroke survivor visits at community health centers and private offices. Results: Young stroke survivor visits comprise 48% of stroke survivor visits at community health centers compared to 31% of stroke survivor visits at the private office setting. Among young stroke survivors cared for at community health centers, 47% were black individuals compared to 14% at a private office setting. The prevalence of hypertension and cigarette smoking was higher in young stroke survivors at the community health center. Conclusions: The community health center is a setting to access young black stroke survivors. Stroke prevention and preparedness interventions should be considered at community health centers.

The influence of vasodilators in the natural history ofmitral regurgitation is controversial. If, on the one hand,they may really interfere, on the other, they may mask leftventricular myocardial dysfunction.Three phases comprise the natural history of mitral re-gurgitation. In the first, increased atrial compliance and ec-centric ventricular hypertrophy are observed in associationwith diastolic normotension. In the second phase, a transi-tion phase, a slow increase in diastolic and left chamber pres-sures is observed. In the third phase, handicapping symp-toms occur due to failure in compensating mechanisms andelevation in the systolic and pulmonary pressures.It is estimated that up to 82% of the patients with mitralregurgitation due to prolapse progress to surgical indicationin a 10-year period, which is equivalent to a 20% rate of sur-gical indication per year

The photoexcited triplet state of two porphyrinoids, H2TTP and a Cd complex of Texaphyrin (Cd‐TxP), oriented in liquid crystals were examined by time‐resolved electron paramagnetic resonance (EPR) spectroscopy as a function of temperature. The low probability of molecular tumbling in the liquid crystalline phase allows the detection of triplets by fast EPR, at temperatures (300 K) which are above the hosts' melting points, and where the fluid properties of the matrices are maintained. Line shape and kinetic analyses of the triplet spectra provide data on spin relaxation rates, interchromophore interactions, and on the dynamic behavior of the liquid crystalline hosts, driven by the external magnetic field.


Abstract The conditions for obtaining squeezing by single-beam multiphoton absorption are examined. For an initial coherent light the amount of squeezing is calculated in the second order of interaction time using the master-equation formalism. A limit formula for the amount of squeezing is found in the case of an initial strong coherent beam. The results are compared with the exact numerical calculations and some remarks are made on the short-time approximation in multiphoton absorption.


The possibility of enhancing the radiation power and monochromaticity by optically induced photonic crystal in the superconducting cavity is proposed and investigated. In such a structure, by periodically irradiating the stacked Josephson junctions and consequently partially suppression of the superconductivity in the irradiated positions due to depairing, a periodic optical configuration is formed. This leads to photonic band gap opening in the range of the terahertz radiation emitted from the layered superconductor. We show that such a photonic band gap significantly enhances the impedance matching at the boundary of the cavity and the waveguide. Since the weak optical coupling of the outer and inner space of layered superconductor samples is a serious reason of reducing radiated power especially in the experiments, the proposed configuration is capable of extremely enhancement in the emitted power along with attenuation of the undesired harmonics.


The northwestern part of the Egyptian Red Sea has attracted the attention of many geologists because it lies at the triple junction of the main rifts between the Red Sea, the Gulf of Aqaba, and Gulf of Suez. The geometry of the fault system in this area of the basin clearly indicates an extensional setting. The area has a southwestward regional dip, and it has experienced more extension than the rest of the Gulf of Suez. Six tectonic stages, different in their stress history, sedimentary fill, and depositional setting, are recognized for the northwestern Red Sea: (1) Cambrian to early Cretaceous stage; (2) late Cretaceous to Oligocene stage; (3) early Miocene stage; (4) early to middle Miocene stage; (5) middle to late Miocene stage; and (6) post-Miocene stage. Magnetic, gravity, seismic, surface, and subsurface data from the northwestern Red Sea delineate several elongate structural highs separated by elongate troughs. Both highs and troughs have the same northwest-southeast direction as the clysmic trend. Some of the highs are dissected by cross elements that trend northeast-southwest and east-northeast-west-southwest and laterally offset these highs. The tectonic framework of the northwestern sector of the Red Sea had a significant influence on hydrocarbon generation, migration, and accumulation. The evidence for this influence includes the following: (1) the troughs form the main source kitchens where the Precambrian basement rocks are present at depths exceeding 4877 m (e.g., Gemsa Trough); (2) the magnitude of throw on the clysmic fault is critical in the entrapment mechanisms; (3) the cross elements play a major role in the hydrocarbon migration and accumulation because they truncate the extension of most of the oil fields and form their bounding faults; and (4) all the discovered oil fields in the study area are structural and/or combination traps and show good matches to the magnetic anomalies.


We report the effect of external electric field (EEF) on the magnetic properties of Mn x Ge 1-x , diluted magnetic semiconductor (DMS). We present a Kondo Lattice Model (KLM) type Hamiltonian with exchange coupling between localized spins, itinerant holes and the EEF. The magnetization, the dispersion and critical temperature (T c ) are calculated for different values of EEF parameters (α) using double time temperature dependent Green function formalism. The enhancement of the (T c ) with the EEF is shown to be a very distinct and is in agreement with recent experimental observation and much required for spintronics applications and devices.

For the first time in this country, an airplane has been developed to both military and Federal Aviation Agency (FAA) requirements, with type certification as a requirement of the military contract. Although fundamentally an exploitation of proven state of the art, the 318,000-lb C-141 has many unusual features and represents the solution of several interesting development problems. Of chief interest are its cargo-handling features, the aerodynamic design of its modestly swept wing and of its T-tail, the derivation of its low-drag fuselage afterbody with full cross-section loadable opening, its stringent weight-control program, its long fan-duct nacelle design, its short nacelle inlets, its flight-station innovations for crew efficiency and comfort, and its unique main-landing-gear design. Rather substantial test programs are still in progress, mainly, by now, in the fatigue and flight areas. The C-141 received its FAA type certificate on January 29,1965.
