The paper contains a proposition of the application of a SRM motor with a modified stator geometry for an electric drive, in particular in an electric bicycle. The study involved a comparison of the cyclicity of the electromagnetic torque and self-inductance in the function of the rotor angle in 2D and 3D models based on the application of the finite element method.


Peptides, such as C‐type natriuretic peptide (CNP), vasoactive intestinal polypeptide (VIP) and endothelin 1 (ET‐1), are involved in the control of penile erectile tissue (corpus cavernosum = CC). Inhibiting the degradation of CNP and VIP or conversion of Big ET‐1 into ET‐1 by endopeptidase enzymes should result in an enhancement of CC smooth muscle relaxation. Using the tissue bath technique, responses of isolated CC, challenged by noradrenaline (NA, 1 μm), to increasing concentrations of the endopeptidase inhibitor KC 12615 (1 nm – 10 μm), CNP and VIP (0.1 nm – 1 μm), were investigated. Effects of CNP, VIP and Big ET‐1 (0.1 nm – 100 nm) on the tissue tension were also evaluated following pre‐exposure to 10 μm of KC 12615. Big ET‐1 induced contraction of the CC amounting to a force generation of 1,200 mg. The contraction was attenuated in the presence of KC 12615 by 35% and 50%, respectively. The tension induced by NA was reversed by VIP and CNP to 38.7% ± 15.8% and 61% ± 13%, respectively, of the initial force. The findings might be of significance with regard to future pharmacological treatment options for male ED, where an endothelial dysfunction exists.

In our laboratory, we deal with characterization of diffraction gratings produced in photopolymers. In such recording systems, the diffraction of light is induced via spatial modulation of refractive index and the diffraction efficiency of transmission gratings can reach values close to 100% due to relatively high values of this modulation. Depending on the exposure condition, the refractive index modulation can reach higher value than its optimum and the efficiency drops. This is an unwanted effect. It is called an overmodulation and it is relatively complicated to find out whether under- or over- modulation occurs. To measure and evaluate this overmodulation effect in transmission gratings we propose a simple method based on multiple/two-wavelength measurement of diffraction efficiency. In this contribution, we would like to present the theoretical idea of the method and also experimental results obtained on photopolymer Bayfol HX.


The adsorption potential of native clay and clay composites was investigated for Golden XGL dye removal from aqueous solution in batch and fixed-bed column modes. Morphological structure and functional groups of the adsorbent were determined by Fourier transform infrared spectroscopy analysis. In batch adsorption studies maximum adsorption capacity was determined by optimization of operational parameters, i.e., pH, adsorbent dose, contact time, initial dye concentration, and temperature. The effects of initial dye concentration, adsorbent bed height, and influent flow rate on fixed-bed column adsorption breakthrough curves were also evaluated. The obtained data was analyzed by the application of different equilibrium and kinetic models. Adsorption of Golden XGL dye onto native clay and clay composites was spontaneous, exothermic, and had great affinity between the adsorbate and adsorbent. The findings of this study revealed that clay composites are a potential adsorbent for cationic dye pollution remediation.


For stationary ergodic diffusions satisfying nonlinear homogeneous Itô stochastic differential equations, this paper obtains the Berry–Esseen bounds on the rates of convergence to normality of the distributions of the quasi maximum likelihood estimators based on stochastic Taylor approximation, under some regularity conditions, when the diffusion is observed at equally spaced dense time points over a long time interval, the high-frequency regime. It shows that the higher-order stochastic Taylor approximation-based estimators perform better than the basic Euler approximation in the sense of having smaller asymptotic variance.


Research studies worldwide have focused on higher education dropout, persistence, and success. Given the profound changes in higher education that have taken place in recent decades, higher education institutions need to compete for students by attracting, retaining, and, ultimately, graduating them. Thus, higher education institutions increasingly offer actions that aim to foster student success. While a smooth and supported process of student transition from secondary to tertiary education is one of the key variables in higher education student retention and paramount for preventing student dropout, the student's overall experience in higher education plays a pivotal role in their performance and success. This paper focuses specifically on higher education students' academic and social involvement, notably through their engagement in extracurricular activities and decision-making processes, which are perceived as critical mechanisms in their persistence in higher education. The study used a qualitative approach with the analysis of four Portuguese higher education institutions. Data were collected through in-depth interviews with students and institutional leaders, complemented with document analysis, and explored through content analysis. The results reveal that, from the wide range of opportunities for involvement offered to students by the higher education institution, activities of an academic nature are the most sought after by students to complement their educational experience. However, students perceive involvement in extracurricular activities in general as critical, both to their overall education and preparation for the labor market and to an easier integration into the institutional environment. Hence, student involvement in cultural or recreational activities, alongside their involvement in institutional decision-making bodies and associative movements, is a privileged way of complementing students' academic training and is perceived by them as important in their overall education, both as professionals and as individuals.


In order to support the rig test of vehicles and compare the degree of correlation between the rig test and road test,this paper first develops a road-load and kinematics data acquisition scheme with NVH transfer pathway theory,and compares the bench response and the road response in time domain,frequency domain,and damage domain.The results have proved that the rig test of vehicles can simulate the road test very well,which provides a feasible path to find the design problems in the development stage and shorten the development cycle of vehicles.


In this article we approach the problem of image search result diversification from a novel perspective that involves the use of relevance feedback (RF). Traditional RF introduces the user in the processing loop by harvesting feedback about the relevance of the search results. This information is used for recomputing a better representation of the data needed. The novelty of our approach is twofold. First, we exploit the RF concept in a completely automated manner via pseudo-relevance feedback; this is while addressing the diversification in priority rather than the relevance. Secondly, we introduce a more efficient visual content representation scheme that exploits Fisher Kernels (FK). It allows to better capture variability of visual keypoints information. We use unsupervised hierarchical clustering to re-group FK descriptors in classes. Diversification is finally achieved with a re-ranking approach. Experimental validation on Flickr data shows the advantages of this approach.


Is there still an effort to include democratic ideals in public education? Some claim that it is no longer a priority, the result of a lack of common defi nition or perceived benefi ts. We agree with Pryor's claim that educational leaders must advocate teaching about the history and values of a democratic society and examine the debates in philosophical thought foundational to educational decisions (2008). School leaders should envision learning as more than content specifi c since one of the primary goals of schooling is to produce effective citizens. In today's policy driven climate, school leaders must transition to new and more effective approaches to enhancing learning and teaching. Aspiring principals/leaders should recognize by now, as we have in Rhode Island, that underperforming students and schools may result in signifi cant reprisals, including dismissal, if improvement is not specifi cally quantifi ed in state assessments. As reforms evolve, research consistently suggests that a key component to effective school change is the democratic process of educating and involving core constituents. However, the tension between collaboration and policy is a reality that often mitigates against a people-centered process. Thus, the leadership base in knowledge, skill sets, practice, and dispositions must target a collective/collaborative effort that recognizes and works through policy demands. This balancing act between constituent involvement on the one hand, and policy expectations on the other, has never been greater. As a result, it has become evident that leadership training must combine creative schemes that are people/constituent inclusive, with an approach that recognizes and balances policy expectations.


In this paper photonic crystal (PC) based coupled cavity waveguides (CCW) were investigated for their true-time delay properties. Linear CCWs formed in a triangular lattice of air holes etched into a dielectric slab were optimized to obtain maximum possible time delays with minimum transmission losses. Depending upon the PC and cavity configurations used, delays in a wide range (0.1 - 0.6 picoseconds for every 1 mum length of CCW) were obtained. These linear waveguides would be ideal to replace conventional phase shifters in the beamforming network of phased array antennas as the effective travel path can be reduced by 52 times as compared to free-space.


The onset of the COVID-19 pandemic has significantly affected the lives of those who work in the tribology and lubrication field Initially discovered in China late in 2019, COVID-19 has now spread throughout the world impacting every region The best scientific evidence indicates that SARS-CoV-2 readily transmits through the air A recent update from the World Health Organization (WHO)1 defines two forms of particles that can cause infection: Respiratory droplets that are five to 10 microns in diameter and droplet nuclei or aerosols with diameters less than five microns The WHO reports that experimental studies conducted under laboratory conditions determined that aerosols containing SARS-CoV-2 can remain in the air for up to three hours For those in the Northern Hemisphere, the summer has been very hot, and air conditioning has been in high demand But concern has been present that individuals in an indoor air-conditioned environment might be highly vulnerable to infection On the other hand, the US Center for Disease Control and Prevention published an article written by researchers in China about an outbreak of COVID-19 generated by individuals eating indoors in an air-conditioned restaurant in Guangzhou, China


In this paper, the effects of elastic support boundary conditions were considered through theoretical analysis,numerical simulation and experiment,and comparative studies were conducted on the inplane and out-plane natural frequency,and the elastic support dynamics formula was established. It was found that: the end restraint stiffness caused some impact on the natural frequency of transmission line, when the elastic stiffness of the end is very large,the results of the two analysis are similar, when the elastic stiffness of the end is very small,the difference between the two results is very obvious; traditional calculation and elastic support theory results are closed with lager stiffness of in-plane vibration,but not the out-plane vibration with a certain span; the effect of elastic support is increased with the transmission lines span decreasing.


Modern cars produced for the last two decades are full of electronic devices called Electronic Control Units (ECU). They are responsible for collecting diagnostic data from different components such as the engine, breaks etc. using probes and sensors. The collected data are validated against built-in heuristic and abnormal behaviour is reported to a driver by a gauge on an instrument cluster. ECUs use data provided by other ECUs. Information is transmitted over the dedicated network called Controlled Area Network (CAN). Every car equipped with ECUs and CAN exposes information over universal diagnostic interface called On-Board Diagnostic. Using the interface, it is possible to gather car's live data. With the data mining approach, it is possible to exploit the collected more effectively to obtain much more information about the functioning of car components than it is provided by standard vehicle equipment. The paper describes how to build a laboratory set to facilitate automated data collection. It consists of three major components: data acquisition, automated logs collection and persistent storage with presentation tools. The first component is based on Torque application for which reverse engineering was performed.


Liquid (water) resistance is applied to actuate motor rather better than frequent sensitive resistance, which will reduce over current impact upon motor while over load startup, some advantages of lower power consumption and good startup performance have been possessed.


In this article, we provide the reader with an idea of realisation an interactive web system for virtual reality (VR). First, we discuss the role of web system for VR, and its relevance and importance. Then, we provide a brief overview of the existing technologies, which allows to implement this idea at the software level. Particularly, we review the possibilities of implementing the functions of the system, which will be gathered in one place: display of standard video and video 360°, with dynamic playlist and descriptions windows; online maps, where the mode of «street view» will be in the focus of attention; output web pages, based on automatic transformation or ready-made «VR mode» of WebVR technology; and the adaptation of the browser to VR, which should solve one of the important problems – user-friendly navigation and ensuring high performance because VR in web has a lot of extra interlayers, instructions translation and etc., and this all decreases the performance. Thus, we are attempting to swap them and make a web-system in the virtual reality system. At the same time, we present our concepts, which clearly demonstrate our idea. Finally, we offer some possible ways of our web-system development in the future.


Transforming growth factor β1 (TGF-β1) is a cardinal cytokine in the pathogenesis of airway remodeling, and promotes epithelial-to-mesenchymal transition (EMT). As a molecular interaction between TGF-β1 and Jun N-terminal kinase (JNK) has been demonstrated, the goal of this study was to elucidate whether JNK plays a role in TGF-β1-induced EMT. Primary cultures of mouse tracheal epithelial cells (MTEC) from wild-type, JNK1–/– or JNK2–/– mice were comparatively evaluated for their ability to undergo EMT in response to TGF-β1. Wild-type MTEC exposed to TGF-β1 demonstrated a prominent induction of mesenchymal mediators and a loss of epithelial markers, in conjunction with a loss of trans-epithelial resistance (TER). Significantly, TGF-β1-mediated EMT was markedly blunted in epithelial cells lacking JNK1, while JNK2–/– MTEC underwent EMT in response to TGF-β1 in a similar way to wild-type cells. Although Smad2/3 phosphorylation and nuclear localization of Smad4 were similar in JNK1–/– MTEC in response to TGF-β1, Smad DNA-binding activity was diminished. Gene expression profiling demonstrated a global suppression of TGF-β1-modulated genes, including regulators of EMT in JNK1–/– MTEC, in comparison with wild-type cells. In aggregate, these results illuminate the novel role of airway epithelial-dependent JNK1 activation in EMT.


GaN HEMTs are being used in power conversion systems due to their fast switching characteristics. While it is possible to achieve high efficiency and power density due to fast switching, GaN HEMT-based power converters have difficulties in practical protection in short circuit and overcurrent situations due to fast switching. In this paper, we analyze the characteristics of GaN HEMT according to the occurrence of short circuit and propose a short circuit protection circuit for GaN HEMT. The method used was to detect the drain-source voltage to check for a short circuit in the circuit and quickly turn off the device through a comparator circuit. The time taken for short circuit protection is 165ns, resulting in effective protection against short circuit scenarios.


For an abelian variety $A$ over a number field $K$, we define the set of Tamagawa torsors of $A$ at a prime $v$ of $K$ to be the set of principal homogeneous spaces of $A$ over the completion $K_v$ of $K$ at $v$ that are split by an unramified extension of $K_v$. In this paper, we study the arithmetic properties of the Tamagawa torsors.


Seproxetine maleate hemi-hydrate was originally formulated with pregelatinized starch, to provide 1 and 20 mg free base equivalent gelatin capsule dosage forms for storage at 25°C and 40°C. HPLC analysis after 3 months revealed the formation of a 1,4 Michael addition adduct in each case. No additional degradation products were detected. To pursue a less interactive formulation, 5 mg formulation equivalent mixtures of seproxetine maleate hemi-hydrate were prepared with pregelatinized starch, lactose, and talc; thus, three distinctly different excipient classifications. These were evaluated in additional isothermal stress experiments at 25°C, 40°C, and 50°C. The results indicated that each excipient interacted with the drug in a unique chemically and thermally dependent manner. Thus, the drug-pregelatinized starch data may be represented by an Arrhenius type relationship, with activation energy of 32 kcal/mol, and formation of the previously described adduct. However, the drug-lactose data suggest reaction ...


Nowadays, consumer trust is identified as one of the most important factors in electronic commerce (e-commerce) growth. This has led much research to investigate the role of trust in e-commerce and determine the factors which influence trust in this area. This paper explores factors which are engaged in building initial consumer trust in online shopping when a consumer wants to buy from a website for the first time. For developing the model and determining factors, data collection is conducted using questionnaire distribution for 325 respondents. After that, the validity of the proposed model is confirmed with Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA). In EFA, variables are categorized into 6 factors and then using CFA which is based on Structural Equations Model (SEM) the relationship between variables and factors is investigated. The results of research show that factors of Product Characteristics, Security & Reputation, Website Design Quality, Support, Purchase Characteristic, and Advertising are effective factors for building initial trust. In this study the statistical population is students of Damghan University.

[Objective] The research aimed to study the effects of different extraction methods on yield of β-carotene from Dunaliella salina and improve the extraction process of β-carotene from D.salina.[Method] Firstly,the effects of two different agents such as acetone∶methanol and petroleum ether on the extraction efficiency of β-carotene from D.salina was compared.With acetone∶methanol(7∶2) mixture as extraction agent,the extraction process was optimized on extraction time,temperature,solid-liquid ratio.[Result] Acetone∶methanol(7∶2) had higher β-carotene extraction efficiency from D.salina than petroleum ether.The extraction efficiency of β-carotene had no apparent diversity on 4 ℃ and 25 ℃.By extraction duration of 5 minutes for three times,high extraction efficiency could be obtained.From 1 ml to 7 ml extraction agent per 0.1 g alga material,β-carotene extraction efficiency appeared to be lightly increased.[Conclusion] With acetone∶methanol(7∶2) as extraction agent,by extraction duration of 5 minutes for three times at the extraction temperature of 25 ℃,high extraction efficiency of β-carotene from D.salina could be attained.


Remote sensing precipitation or precipitation from numerical weather prediction (NWP) is considered to be the best substitute for in situ ground observations for flood simulations in transboundary, data-scarce catchments. This research was aimed to evaluate the possibility of using a combination of a satellite precipitation product and NWP precipitation for better flood forecasting in the transboundary Chenab River Basin (CRB) in Pakistan. The gauge-calibrated satellite precipitation product, i.e., Global Satellite Mapping of Precipitation (GSMaP_Gauge), was selected to calibrate the Integrated Flood Analysis System (IFAS) model for the 2016 flood event in the Chenab River at the Marala Barrage gauging site in Pakistan. Precipitation from the Global Forecast System (GFS) NWP, with nine different lead times up to 4 days, was used in the calibrated IFAS model to predict the flood hydrograph in the Chenab River. The hydrologic simulations, with global GFS forecasts, were unable to predict the flood peak for all lead times. Then, the Weather Research and Forecasting (WRF) model was used to downscale the precipitation forecasts with one-way and two-way nesting approaches. In the WRF model, the CRB was centered in two domains of 25 km and 5 km resolutions. The downscaled precipitation forecasts were subsequently supplied to the IFAS model, and the predicted simulations were compared to obtain the optimal flood peak simulation in the Chenab River. It was found in this study that the simulated hydrographs, at different lead times, from the precipitation of two-way WRF nesting exhibited superior performance with the highest R2 and Nash–Sutcliffe efficiency (NSE) and the lowest percent bias (PBIAS) compared with one-way nesting. Moreover, it was concluded that the combination of GFS forecast and two-way WRF nesting can provide high-quality precipitation prediction to simulate flood hydrographs with a remarkable lead time of 96 h when applying coupled hydrometeorological flow simulation.


Human Resources departments face the unique challenge of providing increased employee services while maintaining staff levels and reducing costs. To reduce costs and the administrative task load on HR, companies will increasingly use technology to educate and provide information to employees. Companies are looking for a system that will integrate with their existing HRMS and those of company benefit providers, allowing such services as online enrollment and other selfservice benefit transactions as well as serving as a gateway to knowledge portals. Knowledge portals make it easier for employees to find answers by recognizing an individual user and bringing information focused on that particular user's needs to the forefront. With so many workers experiencing information overload, simpler methods of accessing data and using online benefits systems are greatly needed.


This presentation is part of an ongoing visual arts project that seeks to capture, re-examine and ultimately transform specific military and religious insignia, as part of an investigation into their interrelated iconogra- phies and histories. Close Range Photogrammetry is being used to provide 3D 'scans' and surface 'textures' of precious objects to very high resolution for use in a range of further processes; from animation to computer aided manufacture. The usual techniques of digital capture and processing tend to struggle with objects that are very small, monochromatic, reflective, or relatively lacking in features. The combination of highly reflective and textured materials, small scale, and detailed embroidery of these objects has required different approaches to achieving the accurate 3D models required. This demonstration will present the apparatus, methods and devices that have been developed to help solve these problems. Together they offer affordable, reliable, and scalable solutions to the traditional challenges of '3D scanning' for particular types of objects, and robust methods applicable to a wide range of situations. They also help reduce the investment (of capital cost, time and labour) required to achieve accurate digital models with high resolution textures, opening up creative possibilities further down the virtual or material 'pipeline'.

Presentation of the Digital Capture project's close-range photogrammetry apparatus, devices and methodology at the international conference: 'Electronic Visualisation and the Arts', British Computer Society, London, July 2017.

This article focuses attention on the problem of pupils who drop out of upper secondary school. One possible solution is to help pupils become better at choosing an educational path and subsequent career. As part of a continuing education study on vocational guidance, school counsellors and teachers worked to develop possible solutions to this problem based on RD adaptive learning and the ideal of pupilship in development.The article presents findings that indicate codetermination – not just involvement –  in the choice of activities, counsellors, education path and a pupil's choice of schools can influence a pupil's ability to make appropriate career choices. The article provides practical examples of how schools can succeed with this, taking their point of departure in the school subject Educational Choices. This subject became obligatory at lower secondary schools from 2008.


Transistor models are very important in the design of Monolithic Microwave Integrated Circuits (MMICs). Circuit simulations based on accurate transistor models are one of the keys to high circuit yield. Transistor models can also be used to trace problems in the device fabrication processes. Hence, transistor models are important in the development of new transistors as well. This thesis considers important modeling aspects for Heterostructure Field-Effect Transistors (HFETs) operated in the 1-110 GHz range. Three categories of experimentally based HFET models are discussed: small-signal models, noise models, and large-signal models. Special attention is paid to efficient direct extraction procedures for small-signal models. Models extracted both for commercially available and in-house fabricated HFET devices are presented. An easy-to-use computer program for automatic data acquisition and device characterization is also presented. In fact, this program has drastically decreased the HFET characterization time. Concerning noise models, extraction methods are proposed for both the single-parameter and the two-parameter FET temperature noise model (also known as the Pospieszalski noise model). In addition, it is theoretically shown that, for every frequency, it is possible to find a pair of source admittances that cancel (balance out) the noise contributions from the two internal noise sources in this model. In this work these admittances are successfully used to obtain simple and exact direct extraction formulas for the two-parameter noise model. Moreover, a new method is presented for noise analysis of linear circuits. The method is easy to implement in general purpose CAD-programs. However, it is also shown that the method can be used to derive analytical expressions for the noise parameters of smaller circuits. The well known drain-current control equation used in the Chalmers nonlinear model is extended to account for temperature, dispersion and soft-breakdown effects. Finally, the importance of monitoring the light-sensitivity of on-wafer characterized devices is addressed. It is shown that light-sensitive devices can have a significant minimum in the drain-current for a specific light-intensity.


In September 2011, the MArine Cable Hosted Observatory (MACHO) was launched in the northeastern sea off Taiwan for surveillance of submarine earthquakes, tsunami, and the ocean environment. The MACHO system, administrated by the Central Weather Bureau, is the first submarine observatory for various science research projects in Taiwan. Based on the MACHO system, we plan to have the marine observatory in the northeast Taiwan (MONET) focused on physical oceanography and ocean acoustics. This paper presents some preliminary results from the data collection of the CTD and acoustic data in the MACHO system. The CTD data show the daily fluctuations due to interactions between the tide and bathymetry. Event detection presents three underwater noise mechanisms, which are earthquake, shipping, and marine mammal. Moreover, we offer an e-research platform for future data exhibition and communication between scientists.


Theoretical analysis of the Motz undulator with a longitudinal magnetic field applied shows that the radiation can be controlled by the magnetic fields varying. The results obtained may be used in the following modeling of the devices with a resonance structures.


Minimum weight along with low vibration level of structures are main desires of engineers in various industries such as aerospace, automobile, and electronics. The metastructures are a kind of nontraditional structures with distributed vibration absorbers without any change in their general shape. In this article, transverse vibration suppression of a proposed metastructure cantilever beam (MSCB) was considered by a lumped mass-spring model. A prismatic cantilever beam with hollow square cross-section, carrying five uniformly distributed absorbers was investigated. Effects of combination of the absorbers' first natural frequency on vibration suppression of the whole structure were examined. Results were validated by finite element method (FEM). Frequency response functions of the MSCB were compared by those of simple prismatic cantilever beams with the same mass. The results showed that the transverse vibration does not always decrease by increasing the number of absorbers. Also, linear combination of the first natural frequencies of absorbers leads to more vibration suppression for the MSCB.


Lisinopryl is one of five most effective ACE inhibitors that have proven themselves in treatment of patients with chronic heart failure with low ejection fraction. In this article we provide new data on Lisinopryl's ability to positively effect remodeling process of the heart tissue. This ability will allow drug's effective implementation in treatment of patients with diastolic disfunction of left ventricle.


Harry Kuitert is, in many respects, a typically Dutch author, or rather, an author who is typical of the reformed culture in the North of the Netherlands in particular. His latest book, Over religie. Aan de liefhebbers onder haar beoefenaars (On religion. To the devotees among its followers) 1 is one of a series of his publications which have become best-sellers in the Netherlands, but are, at the same time, also a subject of much controversy and sharp reactions, both for and against. This clearly shows the debating culture which has risen to great heights in circles of reformed Christians. It is striking that these books, and in particular Het algemeen betwijfeld christelijk geloof Een herziening (The generally doubted Christian faith. A review) (1992) and Jezus: nalatenschap van het christendom. Schets voor een christologie (Jesus, Christianity's legacy. Outline of a christology) (1998)2 have hardly aroused any reaction abroad3. These books, all written after Kuitert had gained a less vulnerable position by becoming an emeritus professor of the (reformed) Amsterdam Free University, apparently touch on typically Dutch issues in a typically Dutch style. Kuitert belongs to the Reformed Churches, a schism in the 19th century from the larger mother church, the Dutch Reformed (Hervormde) Church. Until about thirty or forty years ago, the Reformed formed a tight stronghold of protestant orthodoxy, which, in a way, they still are, as yet another dissident theologian from their circle, Cees Den Heyer, has found to his cost, with his booklet about Verzoening (Atonement).4 However, holes

Justification and Objectives: severity assessment and prognosis assumption of admitted patients are essential characteristics in intensive care medicine. This article aims to describe the epidemiological profile and assess the mortality of patients in an intensive care unit (ICU) according to the calculation of the Simplified Acute Physiology Score (SAPS) 3 through its global and customized (for Latin America) equations. Methods: this is a prospective cohort conducted in an ICU in Sergipe, with cases between September 2018 and March 2019. Clinical, demographic, and standard data to calculate the score were collected from medical records. The Standardized Mortality Ratio (SMR), discrimination, and calibration were calculated for both equations. Results: seventy-eight patients were included; 60% of them were male. The mean age was 61.7 ± 17.2 years. Respiratory infections were the main causes of hospitalization (32.1%). The lowest value of SAPS 3 was 13, and the highest was 90, mean of 65.9 ± 25.5. The mortality observed was 61.5%, and the presumed mean was 47.4% through the global equation (SMR= 1.3) and 57.8% through the customized equation (SMR= 1.04). SAPS 3 showed adequate discrimination and calibration. Conclusion: the study identified a high mortality rate, however, the mean SAPS 3 score also found was higher than most publications. The epidemiological profile found was close to those of other similar units. The equations presented adequate calibration and discrimination, with superior performance of the customized equation.

We designed and recorded seismic surveys to image the steep flank of salt domes, including an overturned salt face, with both high fold 2D and low-fold 3D coverage. The acquisition method, called Sector 3D, consists of high fold 2D radial and strike lines which are recorded simultaneously to also provide low-fold 3D coverage. This recording scheme was designed because of a perceived need for 3D data at basically the cost of a 2D program. The Sector 3D surveys cost about 15% more than the cost of acquiring only the 2D portion of the survey. An overturned salt face with a dip of 110 degrees was successfully imaged with the 3D data. We were unable to image the salt face with the 2D coverage. In this paper, we first describe the design of a seismic survey we call Sector 3D. We then show migration results that demonstrate the need for 3D data. Finally, we propose a modification to the Sector 3D method that we call Seamless Sector 3D.

This presentation will clarify the suggestion made by Gilles Deleuze (on more than one occasion) that we understand the artistic practice of the filmmaker Jean-Luc Godard in relation to the philosophical tradition known as empiricism. In the process, we will gain a better understanding not only of Deleuze's own allegiance to this tradition (particularly, the writings of the seventeenth-century British philosopher David Hume, on whom Deleuze wrote his first monograph) but also an entirely new way of thinking about the nature of cinematic montage. What Deleuze valorizes in both Hume and Godard, philosopher and filmmaker, is the transformed way they engage with the logic of relations that grounds sense and meaning; a transformed engagement that provides Deleuze with the means to distinguish between creative and reified practices of relation. I will suggest that these alternative logics underwrite the division that Deleuze makes between "classical" and "modern" cinema: for whereas the former accepts as given the order in which things seem to occur, and the world made to signify, the latter foregrounds causation as a philosophical problem. The viewer of modern cinema is thus made to reflect on the link between perception, experience and habit, and the possibilities that art opens up for these links to be severed or transformed – and through an engagement with cinematic montage. To demonstrate these claims, I will consider a number of works by Godard, including Ici et ailleurs (Here and Elsewhere, co-directed by Anne-Marie Mieville, 1974), De l'origine du XXle siecle (Origin of the 20th Century, 2000) and Notre Musique (2004).


Background: Miscarriage is the inadvertent loss of a pregnancy before the fetus is viable. The World Health Organization defines this un-survivable state as an embryo or fetus weighing 500 grams or less, which typically corresponds to a fetal age (gestational age) of 20 to 22 weeks or less.Methods: The present study was conducted in the Department of Obstetrics and Gynaecology, M. G. M. Medical College and M.Y. Hospital, Indore from October 2013 to October 2014 on 100 patients.Results: The incidence of first trimester threatened miscarriage, in the Gynaec O.P.D. of M.Y. Hospital, Indore, was 8.8%. The most common risk factor was a history of previous miscarriages in 38% of cases while 9% had advanced maternal age and 35% had advanced paternal age. History of preterm labour was positive in 25% cases and that of congenital anomaly in previous pregnancy in 7% cases. UTI and vaginitis were diagnosed in 10% and 11% cases respectively. Systemic illness was in 24% cases while 6% cases had endocrine disorders. On USG missed miscarriage was found in 8% inconclusive ultrasound was found in 34% cases, rest were normal. Of the 38 cases giving history of previous 1, 2, 3 and more than or equal to 4 miscarriages were 22%, 6%, 8% and 2 % respectively. 36% of the patients presented with bleeding per vaginum. only while 30% had bleeding with pain and 33% cases had only pain in abdomen. On USG 58% had normal scans. USG scan was inconclusive in 34% and only 35% continued with viable pregnancy, rest aborted. 7 of the 100 cases had preterm labour and 51 cases continued to term. Rest 42 aborted. H/o contact, travel, trauma, heavy work did not have any statistically proven effect on outcome of pregnancy.Conclusions: Progesterone assays are currently available in most immunoassay platforms and have shown excellent performance in terms of assay sensitivity, specificity, accuracy and precision with rapid turnaround times. Furthermore, the cost per test for progesterone assay is affordable. Several studies have shown that progesterone is the most specific biomarker for distinguishing viable from nonviable pregnancies. The downfall of progesterone as a biomarker is due to the different cut-off values used by researchers. The cut-off values were also determined on different study populations.


The model for the ca1culation of effeetive thermal parameters in two-layer structure in photoacoustic phenomena proposed in previous works (1-4) is used for defining and ca1culating the effective optical parameters. The concept of effective optical absorption coefficient will naturally emerge from the model when a heat source, depending on the position and the optical absorption coefficient, is taken into account. Results for the static limit shows that, in general case, the effective optical absorption coefficient value depends on the effeetive thermal conductivity, and it is different for rear-surface and front-surface illumination configurations. For optically opaque samples in rear-illumination configuration and optically transparent layers, it is show that the effective optical absorption coefficient and the effective thermal conductivity are independent and can be separately obtained. The latter result suggests for optically transparent samples, it will be correet to use the Maxwell Equations for defining and ca1culating the effeclive oplical parameters in multilayer structures.


Economic interdependence complicates domestic policymaking by interposing the decisions of foreigners in the loop that links policy instrument settings to economic outcomes. Nowhere was this vulnerability to external decisions demonstrated more forcefully—even for the world's major economies—than by the energy supply shocks of 1973 and 1979. The oil shocks posed challenges that offer unusual insight into the way nations choose policies: their severity forced a policy response; their unpredictable timing and (at least in 1973) unprecedented nature ruled out conventional formulas and brought to the fore explicit policy trade-offs. This article seeks to explain how policymakers in the world's two major economies responded to these external shocks. The analysis successively employs three vantage points—system, society, and state—in tracing the sources of domestic adjustment policies. It focuses specifically on the extent to which policies accommodated or extinguished each shock's inflationary impulses and on the coherence and consistency with which the executive in each government formulated and pursued particular policy goals. A comparison of these four cases illustrates the strengths and weaknesses of increasingly detailed theoretical frameworks for explaining policy choice. Although the research does not contradict the depiction of the United States and Japan in terms of state strength, it does underscore the importance of looking beyond formal institutional arrangements to consider how elite policy preferences, ambitions, and capacities can define the way constraints influence policy.


IT is characteristic of tularemia that most patients develop a high degree of natural resistance after infection occurs. The mortality is low. Recovery confers lifelong immunity which protects against subsequent massive exposures with an effectiveness seldom encountered in bacterial diseases. Second attacks of disease are unknown. Local reinfections occur occasionally among immunes subjected to repeated exposures to virulent strains but, as Francis first indicated, they are either asymptomatic or associated with brief and mild constitutional symptoms.' One of us has recorded apparent immunity, due to vaccination, which successfully withstood accidental massive exposures to strains of high virulence.2 Although tularemia is of minor importance as a cause of death it has considerable social and economic importance in areas of high endemicity as a cause of prolonged morbidity and disability. Its capacity to disrupt normal activities of military encampments is recognized.3 The extreme ease with which infection is acquired, and the high infection rates among butchers and market men, scientific investigators, rabbit hunters and their wives and cooks who prepare game for the table, indicate the desirability of better methods of protection than those now in use. Preliminary experiments with heat killed and formalinized Bacterium tularense * suspensions demonstrated clearly that vaccines made by these methods, from either virulent or avirulent strains, provoked severe and extensive constitutional and local reactions upon initial injection into normal individuals. Reasonably well tolerated doses were so small that several months of daily injections were required to produce agglutinin titers to 1:320, a scheme tolerable for a few laboratory workers but impracticable for large scale use. The successful efforts of Ramon and his associates to diminish primary toxicity of toxins and of various bacteria without significant impairment of their antigenicity., by various chemicals, led us to try similar methods. We established the following specifications for an acceptable vaccine:

This report examines the taxation of corporate gains on depreciable business property, an important topic that has received little attention in the economic literature. The analysis reveals that current law, under which gains on such sales are taxed at ordinary tax rates and buyers are allowed to depreciate their purchase cost, places a tax penalty on sales and raises the cost of capital, thereby discouraging investment. In a simple model, three policies would eliminate the impact on user cost and investment: zero taxation of capital gains with recapture of excess depreciation allowances at ordinary tax rates, zero taxation of capital gains with the seller's basis carrying over to the buyer, and reduced tax rates on capital gains. The basis carryover and reduced-rate policies appear to be preferable in a more general framework.


In teleoperation, it is important for an operator to feel as if he really were in a distant place. To realize this objective, the various information from a remote site must be presented to the operator. Even though tactile information is very important to execute a task efficiently, it is not yet sufficiently provided for the operator. We propose a mechanism that can provide more dexterous tactile information to the operator. This device utilizing electromagnetic force is designed to be compact and light enough to attach to the fingerpad, and designed to be controlled continuously. The magnetic circuit is derived by the probable flux paths method in order to take forces at any given dimension. An optimization technique is also proposed to maximize the tactile force that humans can perceive under the same conditions. It is demonstrated that, by optimization, the tactile force increases by 24%, compared with that obtained from the initial design.

This paper presents an active contour based algorithm for tracking non-rigid objects in heavily cluttered scenes. We decompose the non-rigid contour tracking problem into three subproblems: 2D motion estimation, deformation detection, and shape regulation. First, we employ a particle filter to estimate the affine transform parameters between successive frames. Second, by using a dynamic object model, we generate a probabilistic map of deformation to reshape its contour. Finally, we project the updated model onto a trained shape subspace to constrain deformations to be within possible object appearances. Our experiments show that the proposed algorithm significantly improves the performance of the tracker.


In 1952 W. E. Roth proved two theorems on matrix equations using a lemma far more profound than the theorems. Others have produced simpler proofs of the theorems but not of Roth's lemma. We present a method that proves Roth's lemma easily, and is a powerful tool in its own right, enabling us to extend Roth's theorems by giving insight into their underlying structure.

Total Quality Environmental Management (TQEM) has been defined as the practice of applying Total Quality Management (TQM) practices to an organization's environmental effort. TQEM is therefore closely tied with the firm's primary functions and is directly dependent on a firm's competencies. As resource-based theory supports, disaggregating the performance outcomes of internal strategic assets enables identification of the sources of competitive disadvantage and advantage. The contribution of this study was the test of an exploratory, resource-based model linking resources, organizationally-embedded TQEM, and competitive advantage. This study collected survey data from corporations in 15 manufacturing industries and a sample of 143 managers from corporate headquarters and manufacturing plants provided an overall response rate of 27%. Applying moderated, stepwise regression, the majority of hypothesized main effects were supported, but the hypothesized moderated relationships were not supported. The results supported the core theoretical framework which linked the exogenous variable TQEM program implementation with the interim performance outcome of environmental performance. Environmental performance was then successfully linked with the creation of strategic value in the form of protection against competitive threats and exploitation of competitive opportunities, and with the subsequent common proxy for competitive advantage—financial performance.


The jellybean encompasses a large variety of flavors into one simple candy. The chemistry that connects the candy to the science world has an interesting past and an exciting past and present. The ability to extract flavors, or to artificially create them, is a fascinating cascade of reactions which allows food and candy to be colorful and distinct. What lies inside that little shell of hard glucose that allows something that seems so simple to have infinite possibility of taste? Molecules hold the key to understanding the complexity of flavor chemistry. Application of chemical instrumentation, such as gas chromatography can show just what combination of elements create the flavor of food and fragrance that are used in almost everything we eat today.


The mitochondrial calcium uniporter is a highly selective ion channel composed of species-and tissue-specific structural and regulatory subunits. However, the contribution of each component to uniporter-mediated activity still remains unclear. Here, we employ an evolutionary and synthetic biology approach to investigate the functional inter-dependence between the pore-forming subunit MCU and the EF-hand protein MICU1. Using phylogenetic profiling and genetic complementation analyses, we show that MCU and MICU1 constitute the minimal eukaryotic unit of the uniporter, pointing towards a strong selective pressure behind their co-occurrence. Heterologous reconstitution of MCU-mediated and MICU1-gated mitochondrial calcium entry in vivo in yeast cells demonstrates that MICU1 per se is essential to protect yeast from MCU-dependent manganese cytotoxicity. Accordingly, MICU1 deletion significantly sensitizes human HEK-293 cells to manganese-induced stress. Our study identifies a critical role of MICU1 in the regulation of MCU ion selectivity, with potential implications for patients with MICU1 deficiency.


To provide insight on system security and aid decision-makers, we propose a method to quantitatively evaluate the strength of a system's security. Our approach is to create an executable state-based security model of the system under attack. In this paper, we focus on the development of the adversary attack behavior model, which is one part of the overall security model. We show how three key aspects of an adversary's successful cyberattack—means, motive, and opportunity—translate into the notions of probability of success given attempt, probability of attempt, and precondition. Keywords-security quantification; state model; simulation; adversary attack behavior I. QUANTITATIVE MODEL-BASED SECURITY METRICS Making sound security decisions when designing and maintaining a complex system is a challenging task. Analysts need to be able to understand and predict how different factors affect the overall system security. To provide insight on system security and aid decisionmakers, we propose a method to quantitatively evaluate a system's security. Our approach is to create an executable state-based security model of the system under attack. We run discrete-event simulations of the model and collect results on security metrics of interest. Figure 1 illustrates how this method generates answers to security decision questions by incorporating information about the system, its adversaries, and the security metrics. An effective security model should contain information relevant to security analysis. In our proposed state-based security model, possible attack paths into a system are represented as a series of attack steps that incrementally change the state of the model. Each attack step, if successfully executed, can increase the adversary's access or knowledge of the system and move him or her closer to achieving attack goals, such as loss of confidentiality or integrity of specific data or loss of availability of specific services in the system. One key component of our approach is the inclusion of adversary attack behavior models. We assert that meaningful measurements of system security cannot occur in a vacuum void of information about the system's adversaries. A sports team is considered "good" or "bad" depending on how Figure 1. Method for Producing Quantitative Model-Based Metrics its ability to compete compares to its opponents' abilities. Similarly, a system defense should be evaluated in the context of the opponents against which it will likely defend. Different systems face different adversaries. Governmentowned systems are likely to attract attacks from nationstate adversaries. Corporate networks are likely to draw the attention of other types of attackers. To produce meaningful analysis results, security should be analyzed in the context of the specific adversaries likely to attack the system. II. MEANS, MOTIVE, AND OPPORTUNITY FOR CYBERATTACKS Examining the means, motive, and opportunity of a suspect or defendant is helpful in solving mysteries and establishing guilt in criminal cases. The concept of "means, motive, and opportunity" can also motivate the analysis of attacker behavior in the cyber realm. When we construct a model to simulate an adversary (or set of adversaries) attacking a system, we speculate on how different factors drive attack behavior and determine attack attempt outcomes. An adversary may be faced with several potential attack step options. The adversary must first determine which attack steps are available options (i.e., where the adversary has the opportunity to attack) and then determine which available attack step option is most attractive (i.e., where the adversary has the motive to attack). The success of an attempt is determined by the capability of the adversary to execute such an attack step (i.e., whether the adversary has the means to defeat the system defense). We now examine the three stages of an adversary's attack attempt. A. Opportunity: Attack Step Precondition An adversary in the cyberattack realm possesses the opportunity to execute an attack step when he or she possesses some minimum level of system access, system knowledge, and attack skill needed to attempt the attack. Within the security model, an attack step precondition formally states the minimum combination of access, knowledge, and skill needed, as perceived by the adversary. The attack step precondition is a necessary, but not sufficient, condition for an adversary to attempt an attack. For example, when the attack step consists of an adversary gaining corporate network access from the Internet through the company's VPN, the precondition might specify that the attacker must possess Internet access and either knowledge of VPN account log-in information or VPN software exploit skill. An adversary who does not meet the precondition requirements will not attempt the attack step. B. Motive: Probability of Attempt The adversary possesses the motive to execute an attack when he is willing to attempt the attack given the opportunity. Within the security model, this willingness is quantified as the probability of the adversary attempting the attack step. The probability estimate of an adversary possessing the motive to attempt a specific attack includes an implicit assumption of the time period. For some analyses, the time period may be as long as a decade; in other instances, the time period may be a few minutes. The adversary's probability of attempting a particular attack step depends on the relative attractiveness of that attack compared with other attack step options. The adversary first considers all available attack step options, including the option to attempt no attack (the "do-nothing" attack step). The adversary then rates the attractiveness of each option using his or her personal attack goals and attack preferences. Attack goals include achievements such as crashing a web server or stealing credit card numbers from a database. Attack preferences describe the relative importance of four attractiveness measures. The four attractiveness measures are (1) cost to the adversary in attempting the attack step, (2) payoff to the adversary for successfully executing the attack step, (3) probability of successfully completing the attack step, as perceived by the adversary, and (4) probability of being detected by the system during or after attempting the attack step. Different adversaries may have different attack preference weights. A well-funded nation-state may care little about the cost of an attack but may tolerate only very low probability of detection in the attack steps it chooses to attempt. However, a resource-constrained lone hacker may try risker attack steps with a low probability of success and high probability of detection, but the cost to attempt must be low. After the set of available attack step options have been rated with respect to attractiveness to a particular adversary, the adversary chooses one attack step to attempt. In certain circumstances, the "do-nothing" attack may be the most attractive option. Although the "do-nothing" attack step has no payoff, it also has zero cost, no probability of detection, and no probability of failing. In fact, when the "do-nothing" attack is consistently the most attractive attack step option for adversaries, this is a sign of a strong system defense. This situation means that the available attack options are too costly, with too little payoff, too high a probability of detection, and too low a probability of success, from the point of view of the attacker. C. Means: Probability of Success Given Attempt An adversary possesses the means to attack when he or she possesses the capabilities to successfully execute the attack step given that it is attempted. Within the security model, this capability is quantified as the probability of successfully executing the attack step given that it has been attempted. This probability is computed based on the balance of the attack skill of the adversary versus the defensive strength of the system. The defeat of strong system defenses requires more advanced attack skills. These parameters taken together allow us to model the actions of an adversary with respect to a particular system. III. CONCLUSIONS AND FUTURE WORK The adversary attack behavior model is a key part of a larger security model framework. This framework uses precise executable models to produce quantitative security assessments, as shown in Figure 1. A security analysis tool using this framework is currently under development. Meaningful measurements of system security require information about the adversaries. To model attack behavior, we examine how the concepts of means, motive, and opportunity translate into probability of success given attempt, probability of attempt, and precondition in the model. Future work on this project will include case studies and the development of security model validation methods.


Speed of information processing is critical to effective air combat; however, little is known about the effect of gravitational stress on measures of processing speed. To examine, eight young healthy males (26 ± 6 years of age) underwent progressive lower body negative pressure (LBNP) while recording beat‐to‐beat blood pressure (BP), heart rate variability, brain blood flow (MCABF), and while testing simple reaction time (SRT). Baseline values were compared to the last tolerated stage of LBNP (LBNPmax) and the median stage (LBNP50). During LBNP, SRT was significantly slower compared to baseline (Baseline: 280±33, LBNP50: 324±39, LBNPmax: 316±37 ms, P < 0.05). Also, MCABF (Baseline: 65±6, LBNP50: 63±63, LBNPmax: 59±60 cm/s, P < 0.05) and pulsatility index (Baseline: 0.83±0.1, LBNP50: 0.72±0.15, LBNPmax: 0.65±0.1 au, P < 0.05) decreased during LBNPmax. From baseline to LBNP50 a significant correlation existed between changes in pulsatility index and SRT (r = −0.7; P < 0.05). Our data shows that SRT increases during LBNP. Further, it appears that at moderate gravitational stress those with greater reductions in brain blood perfusion demonstrate a more profound negative affect on SRT. At severe LBNP however, SRT does not appear to be related to brain blood flow or indirect markers of sympathovagal tone.

In 2002, Littlejohn and Wellman developed a general left-definite theory for arbitrary self-adjoint operators in a Hilbert space that are bounded below by a positive constant. Zettl and Littlejohn, in 2005, applied this general theory to the classical second-order Fourier operator with periodic boundary boundary conditions. In this paper, we construct sequences of left-definite Hilbert spaces {Hn}n∈N and left-definite self-adjoint operators {An}n∈N associated with the Fourier operator with semi-periodic boundary conditions. We obtain explicit formulas for the domain of the square root of the self-adjoint operator A obtained from this boundary value problem as well as explicit representations of the domains D(A) for all positive integers n. Furthermore, a Fourier expansion theorem is given in each left-definite space Hn.

Nowadays, wireless communication technologies are being employed in an ever increasing number of different application areas, including industrial environments. Unfortunately, because of several reasons, among which their random access technique, they are not usually considered suitable for connecting devices at the field level. In this paper, the performance that can be achieved by QoS-enabled WLANs (e.g., IEEE 802.11e networks) to support communication in industrial environments is analysed in depth. In particular, it is shown that they can be profitably adopted even at the shop-floor, provided that there are not critical safety requirements or tight timing constraints. Despite the lower determinism and reliability, the resulting performance resembles closely that achievable with fieldbuses.


As functional laryngitis is to be the subject of another part of this symposium, the differential diagnosis and treatment of organic laryngitis only is here presented. It is to be differentiated from affections of the larynx caused by constitutional affections such as syphilis, tuberculosis, lupus aunl scleroma; from the benign laryngeal growths, papilloma, mucocele, etc.; from malignant growths which so frequently involve the larynx; from prolapse of the ventricle; from lesions of the mucous membrane allied to affections of the skin as pemphigus, and from lesions caused by interference with the nerve supply of the larynx, the abductor and adductor paralyses. It is not necessary here to go into detail of the differential diagnosis. The mere mention of the various ailments that may similate chronic laryngitis is quite sufficient to indicate what we have to bear in mind and against which we have to guard in making our diagnosis.

Abstract The issue of who should be included and recognised as professionals in the early childhood education and care (ECEC) service system is both contested and pressing in the current policy climate. At stake is a high-quality early childhood care and education service system that is both responsive and appropriate to the constituency it serves. A review of the history of ECEC professionalism reveals complex entanglements and debates regarding professional belonging. Services that deliver education and care to children and families living in high poverty contexts are often excluded from ECEC professionalism debates. Drawing on notions of rationality, emotionality and criticality presented in recent accounts of ECEC professionalism, we use data collected from interviews with service providers delivering services to children and families living in high poverty contexts in Australia to develop an account of criticality that is pertinent to current funding and policy contexts. We argue that these service providers' perspectives about their own professionalism have much to offer broader debates.

This chapter tracks the trends of the contemporary vampire in the twenty-first century, from the vampire's popular representation as an outsider and anti-hero, a carrier of a fatal plague, through to an idealised figure of desire in Gothic romance. Vampires in literature, film and television evidence their continued struggle as displaced figures caught between the ancient and the modern while remaining perfectly in tune with the zeitgeist. This chapter analyses the cultural assimilation and aggressive marketisation of the vampire narrative into separate strands for multiple audiences and generic configurations (from the Gothic romance to the action film), exposing the plurality of vampiric representation in the twenty-first century, including the tamed Gothic lover of the Twilight saga (2008–12), the ubiquitous and the synthetic nature of contemporary vampire society (HBO's True Blood(2008–14)), and the persistent updating of popular twentieth-century vampire narratives, including Bram Stoker's novel Dracula(1897), for a new century.


This paper investigated the effect of variable normal load on the fretting fatigue mechanism. A kinetics-based Q-P curve analysis method was proposed to assist testing system design and experiment result analysis. Based on this method, a biaxial fretting fatigue testing system was designed. Experimental and numerical investigation was carried out to discuss the effect of biaxial loading phase difference (the phase difference between bulk load and cyclic normal load) and stiffness ratio (the stiffness ratio between pad fixture and flat specimen) on the fretting fatigue mechanism. Based on the critical plane approach and proposed Q-P curves analysis method, it is found that the fretting status is partial slip regime under small stiffness ratio conditions. The stress/strain which is influenced by phase difference is the main factor of fretting fatigue damage in this condition. Furthermore, the mean stress of the normal load on the critical plane is compressive stress. It directly influences the fatigue damage under partial slip regime. With the increase of stiffness ratio and phase difference (from 0° to 90°), the fretting status changes from partial slip regime to gross slip regime, which means that the influence of wear increases. Wear inhibits the initiation of fatigue cracks, which has a positive influence on fretting fatigue life. As a result, the fretting failure mode gradually changes from fatigue to wear.


Stability of the Pd x In y systems. Initially, we performed structural optimization of Pd, In, the intermetallics PdIn, Pd 2 In, Pd 3 In, and solid solutions of In in Pd of approximate composition Pd 98 In 2 and Pd 90 In 10 (at.%). The crystal structures for the intermetallic compounds were retrieved from literature. 1,2,3,4 Models from solid Pd-In solutions were generated taking as base the Pd fcc conventional cell. The Pd 98 In 2 composition was modelled from the 2×2×3 expansions of bulk Pd, containing 48 atoms, and replacing one of them by In. The Pd 90 In 10 composition was modeled from the 2×2×2 expansion, containing 32 atoms,

I was interested to read the paper by Acs B and colleagues published in the Jun 2016 issue of Diagn Cytopathol. They aimed to assess the diagnostic accuracy of ancillary tests applied to fine-needle aspiration cytology (FNAB) in breast tumors and metastases, as a favorable first choice. The authors compared ER and Her2 immunocytochemical (ICC) as well as immunohistochemical (IHC) staining and HER2 fluorescence in situ hybridization (FISH). First of all, reliability (precision) and validity (accuracy) are two completely different methodological issues which should not be confused. (Title of the paper and the aim of the authors indicate to this confusion). They reported that significant difference (P< 0.001) and moderate correlation (j 5 0.44) were noted between results of 97 paired ICC an IHC reactions for ER expression. Considering large sample size, statistically significant (P value< 0.001) differences can easily be obtained; however, clinically importance of the observed difference should be taking into account instead of statistically significant. Moreover, for qualitative variables, weighted kappa should be used. It is crucial to know that simple kappa has two important limitations as below. It depends on the prevalence of each cell (concordant and discordant cells) as well as the number of the categories (the higher the categories, the lower our kappa value. As the authors pointed out in their conclusion, FISH performed on FNAB samples is suitable to categorize primary and metastatic breast cancer in regard of HER2 gene amplification status and can be used as a predictive test in respect of therapies targeting HER2. For prediction, we need two cohort dataset otherwise, we should split one cohort dataset to develop and validate our model. It means without validation, we cannot generalize our results. Therefore, such a conclusion can be a misleading message and misdiagnosis as well as mismanagement of the patients cannot be avoided.


ABSTRACT While human-centered system design has actively sought to reduce cognitive biases in decision-making, a gap exists on the distinct role of media features in decision-support systems (DSS). Intuitively, we may presume that DSS interactivity and revisability remedy such biases. Yet, experiments reported herein reveal that combining the two features may conversely aggravate such bias. These features have been studied as distinct factors moderating bias in decision-criteria rating tasks in two experiments (sample sizes: n1 =96 for first; for second with criteria vividness controlled, n2=429). Such study emanates from a novel view of DSS as persuasive communication media. Thus, a unique adaptation of Media Synchronicity Theory to a computer–human communication context ensues. This promotes the isolated study of interactivity and revisability, alongside their interaction. Hence, the study finds statistically significant bias reductions for revisability treatments without interactive feedback. Such real-time automatic feedback, surprisingly, makes no impact in the majority of cases. Vividness controlled, it is still revisability-only cases indicating any reduction in possible order effects bias (despite extra effort required). Thus, a fresh case is made to evaluate interactivity and revisability separately in DSS media, with empirical evidence that – together – they could be 'doing more harm than good'.


This work presents the results of the study of the antibacterial properties of samples of TiO2, TiON, TiN, TiAlN, TiO2:V2O5 ultrathin films synthesized by Atomic and Molecular Layer Deposition (ALD/MLD) techniques. The studies were conducted on the colonies of the E. coli and S.aureus bacteria. It was found that samples of TiON films exhibit the greatest antibacterial activity. After an hour of exposure of the TiON samples under UV light with 365 nm wave length in presence of colonies of E. coli bacteria, the activity was 93.32%, and under normal daylight it was 74.60%, which is higher than for undoped TiO2 samples with activity of 53.80% in UV light and 21.1% in daylight. Similar results were obtained with colonies of S.aureus bacteria, where the efficiency values were slightly lower due to the higher viability of these bacteria.


The purpose of this experiment is to improve the optics of an intense H− negative-ion beam, to be used in future Tokamaks. The emittance diagnostic has been installed in the experimental setup INCA, to perform an optimization of a negative-ion injector preaccelerator. The first stage of this work consists of testing the operation of the electric-sweep scanner, to measure the beam current in the two-dimensional-phase space and to investigate the diagnostic performances. In addition to the measurement of H− angles, we can scan the angles of the fast H+ created along the beam in the transport region and test the efficiency of the electron magnetic trap installed in the second accelerator grid (extraction electrode). We also observe the presence of a neutral component. This analyzer not only provides a diagnostic of the beam divergence but also improves of the knowledge of the beam components. We studied two accelerator configurations. The first one permitted to obtain an optimal beam optics under 15 keV. The...

Review of the effects of different perturbations of optical fibers shows that their physical effects are generally identical: that usually is the transfer of the lower-order modes (as measured in the far field) to the higher-order modes of the fiber. This is so for the general classes of microbends, macrobends, pressure variations, temperature variations, and chemical changes. This means that rather than being truly different perturbations, they are physically really the same thing. Each represents a true gauge-invariant perturbation plus a piece that is merely a gauge transformation. Each perturbation is then transformable, and their apparent differences are physically trivial. We take as our points of departure the perturbed fiber discussions of Snyder and Love1 and Hill's2 analysis of differential equations from their group invariance properties. We analyze the modal structure of unperturbed fiber in terms of the invariance group of the wave equation for the appropriate fiber geometries and boundary conditions and then show how their perturbations consist of a true physical piece and insignificant parts that are just gauge transformations of each other.


In this paper, we deal with the performance of nonorthogonal Amplify-and-Forward (NAF) protocols over block-fading channels. In contrast with previous studies, which assume that the channel remains constant over the whole cooperative frame, here we relax this constraint and assume a block fading channel which changes during the cooperation. Despite this additional channel diversity degree, channel inversion amplification schemes are unable to increase the diversity gain of the system due the high correlation between the two simultaneous diversity branches. We propose a fixed gain amplification factor which efficiently uses the additional diversity degree of the channel and recovers the diversity loss associated with channel inversion schemes. The diversity analysis is based on some well-defined capacity bounds which follow the diversity order of the true capacity.


Cyber‐physical systems are fundamental to operations of many safety critical systems, from power plants to autonomous cars. Such systems feature a control loop that maps sensor measurements to control decisions. In many applications, these decisions involve maintaining system state features, such as temperature and pressure, in a safe range, with anomaly detection employed to ensure that anomalous or malicious sensor measurements do not subvert system operation. Although anomaly detection has been studied in the literature, many existing approaches focus on the cases with passive adversaries. Our first contribution is a novel stealthy attack on systems featuring Gaussian Process regression (GPR) for anomaly detection—a popular choice for this task. Next, we pose the problem of robust GPR for anomaly detection as a Stackelberg game and present a novel algorithmic approach for solving it. Our experimental evaluation demonstrates both the vulnerability of baseline systems to attack, as well as the increased robustness offered by our approach.


This article provides a review of recent work in social science exploring the meaning of risk in contemporary society and its relation to science and science policy-making. The article argues that we have seen a reflexive turn in policy-making though this is limited and yet to fully embrace the discourse of uncertainty and lay engagement with science that will be required for a more socially robust and legitimated management of risks. It locates risk in a wider political culture and calls for new research that adopts a more sophisticated approach to the social framing of the science–risk–policy nexus.


The handwriting identification facet of questioned document examination suffers from the lack of statistical data concerning the frequency of occurrence of combinations of particular handwriting characteristics. While document examiners tend to assign probative values to specific handwriting characteristics and their combinations, judgments are often based almost entirely on the examiner's experience and power of recall. Since handwriting identification is a scientific pursuit, statistical data concerning frequency of occurrence of forms and combinations would seem to offer some promise for providing a basis for the opinions of document examiners.


Concerned that millions of the world's poorest and hungry people remain in poverty and hunger, the International Food Policy Research Institute (IFPRI) facilitated a consultation process, which includes the conference "Taking Action for the World's Poor and Hungry People" on October 1719 in Beijing, to examine what new and different action is required to improve their welfare." Of the 400 participants who attended, 117 completed a survey (for the questionnaire see ANNEX I) intended to assess their observations regarding the conference.


This paper proposes a novel technique to estimate online the inductances of a Permanent Magnet Synchronous Machine (PMSM) based on the measurement of the current derivatives excited by two active-voltage vectors and one zero-voltage vector within a PWM cycle. The d- and q-axes inductances of PMSMs are calculated during normal operation of the drive system. The influence of the magnetic saturation effect on the machine's inductances is also considered by the proposed estimation method. The full system simulation and experiment were implemented to verify the effectiveness and robustness of the proposed method.

ADAM17 is a disintegrin and metalloproteinase initially described to cleave the tumor necrosis factor α (TNFα). Currently, it is known that it can also release ectodomains of a diverse variety of molecules such as, transforming growth factor α (TGFα), L-selectin, and angiotensin-converting enzyme 2 (ACE2). It has been shown that ADAM17 protein expression increases in kidney mesangial cells after incubation with high glucose media mimicking what has been observed in diabetic patients and experimental models of diabetic nephropathy. We now studied the effect ADAM17 deletion on human kidney cells (HKC-8) in a 3D spheroids in vitro cell culture incubated with high glucose, low glucose and mannitol medium resembling the in vivo human kidney diabetic environment.

 ADAM17 deletion was performed using the CRISPR/Cas9 technology. HKC8 cells grew inside a RGD-functionalized dextran hydrogel to obtain 3D spheroids. 13 days post-seeding, the spheroids were incubated with 35mM of D-glucose (HG), 5mM of D-glucose (LG) or 35mM of mannitol as osmotic control for 6h, 24h or 72h. The quality of the established 3D cell culture of mature HKC-8 spheroids was assessed by Aquoporin-1 and Glut-1 staining. After incubations quantitative-PCR analyses were performed for fibrotic and inflammatory markers. Immunofluorescence for fibrotic markers was performed on HKC-8 spheroids incubated for 72h.

 High glucose (HG) medium induced CCL5 gene expression on wild-type HKC-8 spheroids after 6h and 24h of incubation in comparison with the control group. Interestingly, in the ADAM17-deleted spheroids, CCL5 gene expression maintained similar to control after 6h of incubation with HG medium and tended to decrease after 24h of incubation in comparison with the wild-type. Collagen IV gene expression was increased in the wild-type spheroids incubated with HG in comparison with the control group. In ADAM17-deleted spheroids, Collagen IV gene expression was significantly decreased in the cells incubated with HG in comparison with the wild-type cells incubated with HG. HG increased the expression of α-SMA, fibronectin and Collagen IV in wild-type spheroids. Adam17 deletion blocked the increase of α-SMA, fibronectin and Collagen IV expression compared with wild-type cells after 72h of incubation.

 ADAM17 blockade protects against fibrosis and inflammation in human kidney tubular spheroids under high glucose.

Abstract Chinese culture has remained steady, stretching through time as long and unbroken as the Great Wall. In thousands of years, Chinese culture has exhibited a remarkable ability to assimilate foreign intrusions. Even though several times throughout Chinese history minority nationalities have been in military and political control of China, they were gradually assimilated by Chinese culture. Christianity has spent more than a thousand years attempting to convert the Chinese with only negligible success. However, why was Marxism able to become the dominant ideology in only 30 years? This article discusses the critical cultural roots of the different destinies of Marxism and Christianity within the Great Wall.


Omphalocele is frequently associated with other congenital anomalies which have influences on patient's prognosis ' . W e i n v e s t i g a t e d w h e t h e r t h e r e w e r e s o m e o t h e r f a c t o r s associated with mortality in omphalocele. In recent 6 years, 26 cases with omphalocele have been treated at our institute. There were 19 cases of middle celosomia, 6 cases of lower celosomia and 1 case of total celosomia. The cases of middle celosomia contained Λ cases of chromosomal disease and 6 cases of EMG syndrome. Although the overall incidences of major anomalies and severe complications associated with middle celosomia without chromosomal abnormalities or EMG syndrome was small , those of lower ce losomia was 100%. In addi t ion to urogenital anomal ies , all cases of lower celosomia and total celosomia were associated with undersized lung ( which was indicated by the lung to body weight ratio ) , scoliosis, and intrauterine growth retardation ( I U G R ) . Using data gathered from 6 cases of middle celosomia and one case of total celosomia, the chest circumference( CC ) to occipital frontal circumference( OFC ) ratio. CC/OFC ratio of all 7.cases were under 0.73, which also were defined undersized lung '. Twenty six cases placentas were examined . The average umbilical cord 's length of middle celosomia was 39·1cm and that of EMG syndrome was 7 4 « 2 c m , which compl ica ted with long umbilical cord. However, that of lower celosomia was 7.2cm and that of total celosomia was 68.0cm, which revealed very short umbilical cord. In addition to this very short umbilical cord, a l l 7 c a s e s c o m p l i c a t e d w i t h s ingle u m b i l i c a l c o r d . The mortality rate in lower and total celosomia(100%) was higher than tha t o f m i d d l e c e l o s o m i a ( 0 % ) w i t h o u t c h r o m o s o m e abnormalities or EMG syndrome. This difference may be due to the associated major anomalies, lung hypoplasia and IUGR. The measurement of C C / O F C ratio by ul trasound graph is useful to predict undersized lung. The diagnosis of scoliosis, single umbilical cord and the measurement of umbilical cord's length by u l t rasound graph were usefu l to predic t in fer ior celosomia and EMG syndrome. These ultrasound findings may be impor tan t not only for prenatal diagnosis of the type of omphalocele, but also for prediction of prognosis.


Radiation of a medium that is stationary under the influence of an external homogeneous electrostatic field is considered in the case when the fluctuating velocity of the medium is a random function of coordinates and time. A general expression for the intensity of a scattered field in the Fraunhofer zone is obtained.


Deviated fractures of the quadrilateral plate represent a challenge to the surgeon. Several forms of treatment have been described in the literature, with a recent focus on open reduction and internal fixation with buttress devices. We present a case of a young patient with fracture of the quadrilateral plate without involvement of the columns, treated with open reduction via modified Stoppa access and fixation using acetabular reconstruction plate and anti-shear screws. He presented a satisfactory result and returned to previous activities.


Recycling of thermoplastic polyolefins bumper has been carried out by stirring a coarse-crushed plastic material inside a chemical reactor using dichloromethane(MC) to release the paint film and drying the solvent. Chemical method adversely affects the physical properties or surface quality of the final product. It was found that wettability and surface tension of these polymers did not influence coating properties significantly. The diffusion coefficient of MC in PP/EPR blend has been monitored using an attenuated total reflection T-IR. The test also demonstrated both the accuracy and quickness of FT-IR ATR experiment for measuring the diffusion coefficient of chemical recycling system. Crystallinity and fractional free volume were very sensitive to the diffusion rates of small molecules in polymers as well as to the composition in recycled PP/EPR blends.
It was suggested that concentration of the PP/EPR resins obtained from recycling process must be lower than 40wt. percent in compounding.


One disclaimer is necessary: while in principle this factorization result makes it clear that representation theory is relevant to study of automorphic forms and L-functions, in practice there are other things necessary. In effect, one needs to know that the representation theory of reductive linear p-adic groups is tractable, so that conversion of other issues into representation theory is a change for the better. Thus, beyond the material here, one will need to know (at least) the basic properties of spherical and unramified principal series representations of reductive linear groups over local fields. The fact that in some sense there is just one irreducible representation of a reductive linear p-adic group will have to be pursued later.
