The ampullary carcinomas represent 7% of carcinoma arising in pancreatobiliary region. Adenocarcinoma is the dominant histological type, observed in 90% of cases. The determination of the intestinal or pancreatobiliary origin have a double interests; prognostic and therapeutic. The aim of this study is to evaluate the value of histological examination in determining the origin of ampullary carcinomas. We reviewed 35 cases of ampullarytumors, collected in the Department of Pathology of Hassan II university Hospital of Fez (Morocco) over a period of 2 years. Two pathologists reviewed, independently, all the cases, without clinical or radiological information. They were based on histological criteria defined in the WHO classification of digestive tumours. The Kappa coefficient is used to assess agreement. Our study showed a medium reproducibility of histological examination in the diagnosis of ampullary carcinomas, with good agreement for the intestinal type. The distinction between these histological subtypes is required given its prognostic and therapeutic implications. The standard histological examination allows in most cases the determination of intestinal or biliopancreatic origin, based on architectural criteria and cyto-nuclear. Using immune histochemical supplements prove necessary in the loss morphological criteria or discordant cases overlap.

The investigation aimed at the evaluation of EEG activity during stereoscopic perception of images with different levels of visual comfort. Different levels of disparity and the number of details in stereoscopic views in some cases make it difficult to find the focus point for comfortable depth perception quickly. During our investigation, we found a tendency for differences in single sensor-based EEG signal activity at specific frequencies. A dataset of EEG signal records from 19 control subjects was collected and used for further evaluation. To support the reproducible research this dataset of EEG activity with associated subjective scores was made publicly available. During the experimental investigation, we found differences in EEG signal activity at different levels of visual comfort. In addition, the dynamics of EEG signal activity correlated to the moment of depth perception indication registered by the control subjects. The results of our investigation show that the ratio of alpha estimated from a single EEG sensor placed over the frontal lobe can serve as a complementary feature for the automatic detection of visually uncomfortable stereoscopic views.


In this paper, we propose a semi-automatic depth estimation algorithm whereby the user defines object depth boundaries and disparity initialization. Automatic depth estimation methods generally have difficulty to obtain good depth results around object edges and in areas with low texture. The goal of our method is to improve the depth in these areas and reduce view synthesis artifacts in Depth Image Based Rendering. Good view synthesis quality is very important in applications such as 3DTV and Free-viewpoint Television (FTV). In our proposed method, initial disparity values for smooth areas can be input through a so-called manual disparity map, and depth boundaries are defined by a manually created edge map which can be supplied for one or multiple frames. For evaluation we used MPEG multi-view videos and we demonstrate our algorithm can significantly improve the depth maps and reduce view synthesis artifacts.

Andrographis paniculata has been used for centuries as a medicinal herb for the treatment of upper gastrointestinal tract and upper respiratory infections, fever, herpes and other chronic diseases. It is widely used in Ayurveda as a popular remedy for the treatment of various liver disorders. Phytochemical investigation of this well studied herb showed that it is a rich source of bioactive flavonoids and diterpenoids. The structures of these compounds have been established on the basis of various spectral studies. Detailed research regarding the phytochemical and pharmacological aspects of the A. paniculata leads to the fact that it is a valuable source of unique natural products for various medicinal applications. The main objective of this article is to review the literature of A. paniculata specifically articles pertaining to therapeutic benefits, chemical properties, pharmacological evaluation and toxicity.


The adsorption process of nitrate from an aqueous solution by using activated Gamalama volcanic ash was investigated. Gamalama volcanic ash (VA) was activated with HNO3 2M. The effect of adsorbent mass and initial nitrate concentration on nitrate adsorption were observed in this study. The adsorption process was conducted using a various mass of adsorbent (1 g, 2 g, 4 g, 6 g, and 8 g), various initial concentrations of nitrate (20 mg/L, 30 mg/L,40 mg/L, 50 mg/L, and 60 mg/L). The increasing of adsorbent mass decreased the adsorption capacity was observed. It was also found that the increase in initial concentration increased the adsorption capacity. The highest nitrate adsorption capacity showed by 1 gram adsorbent for 0.167 mg/g, and at nitrate initial concentration 80 mg/L, for 1.831 mg/g. Adsorption isotherm of nitrate on activated VA was determined and figured. These isotherms were modelled according to Freundlich and Langmuir adsorption isotherm.


Understanding the filling process in response to variation of lake-level is important in faulted basin. In this paper, numerical simulation has been applied to analyze the filling characteristics of the Songliao faulted basin. To assess the effect of different parameters on the filling characteristics, lake-level change, tectonic subsidence and sediment supply are taken into consideration. Based on the filling features of the Songliao faulted basin, we simulated filling characteristics of this faulted basin during 3 lake-level fluctuated periods, in which tectonic subsidence and sediment supply are supposed as constants, and the lake-level change follows a sin-function. The modeling results indicated that: ① Variation of lake-level in the faulted basin is well compared with the global sea-level change. One cycle of lake-level change results in formation of a corresponding sequence, in which a sequence boundary formed at the lowstand period of lake-level; ② Amplitude of lake-level change controlled the distribution of corresponding sequence unit, the larger the lake-level change is, the larger the distribution area and the thicker the sedimentary thickness of the corresponding sequence are; ③ The sequence units due to lake-level change are well reserved at following favorable conditions, such as the subordinate lake-level change under the background of a continuous rise of lake-level or tectonic subsidence. The numerical modeling results in agreement with measured sequences have demonstrated the architecture of sequence units and filling processes in the Songliao faulted basin.


This paper presents a simulation method for oil spills in a multi-island area. The simulation considers three parts, which consist of the spreading of an oil slick on its edge as well as the diffusion and drift under dynamic actions, the evaporation and spreading thickness of an oil slick in its interior, and the adsorption and emulsification near shorelines and islands. The Euler-Lagrange method is adopted to track the spill location and particles positions on the edge of oil slicks. A mathematical model of marine oil spills is established for the Luanjiakou District of the Port of Yantai. The flow field verification shows that the BIAS of tidal level, flow velocity, and flow direction is below ±10 cm, 0.11 m/s, and ±2°, respectively, and the oil spill verification captures satisfactory results. Hence, the proposed model could reproduce the oil spill process in this region. Then, we simulate oil spills under various operating conditions. It is concluded that the transport of oil slicks is mainly influenced by flood/ebb currents, whereas the wind plays a major role in the drift and thickness of oil slicks. The study provides an important reference to controlling and handling of accidental oil spills.

In this paper we investigate the accuracy of two numerical procedures commonly used to solve 2D advection problems: spectral and finite difference (FD) schemes. These schemes are widely used, simulating, e.g., neutral and plasma flows. FD schemes have long been considered fast, relatively easy to implement, and applicable to complex geometries, but are somewhat inferior in accuracy compared to spectral schemes. Using two study cases at high Reynolds number, the merging of two equally signed Gaussian vortices in a periodic box and dipole interaction with a no-slip wall, we will demonstrate that the accuracy of FD schemes can be significantly improved if one is careful in choosing an appropriate FD scheme that reflects conservation properties of the nonlinear terms and in setting up the grid in accordance with the problem.


The ability to pursue speciic goals is essential for purposeful autonomous navigation. Goals usually refer to objects in the environment whose position is stored in a map. To eeectively use this information, the robot needs to translate absolute positions in the map into internal coordinates, based on an estimate of its own position in the map. We describe a technique to incorporate map information into a fuzzy controller when this estimate is approximate, and it is represented by a fuzzy set. We illustrate this technique by showing an example on a mobile robot.

This work is about using a space-time evolution mathematical model for tumors, for the aim of controlling them. The mathematical model used is based on the three compartments approach [1]. The model is a Hybrid automata mainly built according to the treatment strategy itself, which consists of checking the cells in one compartment, and to free them once the eliminating agent is at its optimum potential of elimination. After that, robust control laws are developed for each control mode. These control laws are mainly inspired from the differential geometry methodology, and the sliding modes approach with some improvements. Finally, simulations are done and results discussed.


T regulatory cells (Tregs) play an important role in the induction and maintenance of immunological tolerance to self and alloantigens. Recent findings in experimental transplant models have demonstrated that Treg could control and delay allograft rejection. Induction of immune tolerance decreases the risk of acute and chronic graft rejection after solid organ transplantation and can improve transplanted organ survival. Tregs are being tested in trials as a potential therapy in cell and solid organ transplantation. However, as we know, regulatory T cells (Tregs) are crucial for peripheral tolerance and are intimately involved in cancer. The influence of Tregs on cancer progression has been demonstrated in a large number of preclinical models and confirmed in several types of malignancies. Neoplastic processes trigger an increase of Treg numbers in draining lymph nodes, spleen, blood, and tumors, leading to the suppression of anti-tumor responses. In this review, we summarize some of the critical aspects of the immunoregulatory function of Treg cells in cancer and transplantation and discuss their potential research progress and challenge.


In this short manuscript, we briefly recall some well-known methods for obtaining gradient bounds of viscosity solutions for elliptic and parabolic equations. The two methods we focus here are the idea coming from Ishii- Lions' method applies for strictly elliptic equations and the other one is socalled weak Bernstein's method developed by Barles applies for degenerate equations. We present some results based on these methods and their applications. We also discuss some promising extensions in the future.


The Standard Model of particle physics can be deduced from a small number of axioms within Connes' noncommutative geometry (NCG). Boyle and Farnsworth [New J. Phys. 16 (2014) 123027] proposed to interpret Connes' approach as an algebra extension in the sense of Eilenberg. By doing so, they could deduce three axioms of the NCG Standard Model (i.e. order zero, order one and massless photon) from the single requirement that the extended algebra be associative. However, their approach was only applied to the finite algebra and fails the full model.

By taking into account the differential graded structure of the algebra of noncommutative differential forms, we obtain a formulation where the same three axioms are deduced from the associativity of the extended differential graded algebra, but which is now also compatible with the full Standard Model. Finally, we present a Lorentzian version of the noncommutative geometry of the Standard Model and we show that the three axioms still hold
if the four-dimensional manifold has a Lorentzian metric.


IEEE 1584 equations do not cover single-phase faults based on the assumption that most of them escalate to a three-phase fault for which this standard applies. If IEEE 1584 equations were used for a single-phase fault, the results would be conservative based on the standard. Most of the short circuit, and fault calculation reference material cover three phase systems. Nonetheless, there are many commercial, and industrial systems, which are single phase. That is, they either feed from a single-phase source, or branch off a 3-phase system. These systems can, too, experience faults, and arc flash, where there aren't good references to cover them. Fault current calculations in single phase systems can be more challenging than a three-phase system due to lack of existing work. In this paper, we present an approach to simulate faults in single-phase systems through a three-phase model. The method is useful since once the equivalent 3-phase model is created both fault, and arc flash calculations can be performed like any other three-phase system. That is, the device curve and the calculated current can be used to obtain the incident energy. The scope, limitations, and details of the method will be presented with some examples.

ABSTRACT With the advance of sequencing technology, the number of sequenced plant genomes has been rapidly increasing. However, many plant proteins in public databases are recognised as proteins with domains of unknown function (DUF). DUF872 is such a protein family that consists of plant proteins with unknown function. In this study, we analysed three DUF872 members (OsDUF872.1, OsDUF872.1 and OsDUF872.3) in rice Nipponbare with three distinct motifs. Real-time polymerase chain reaction showed that the expression patterns of the three corresponding OsDUF872 protein-encoding genes varied in 15 different rice tissues. The expression of OsDUF872.2 was significantly (P < 0.01) upregulated under salt, cold and heat stress conditions. Overexpression of OsDUF872.2 in Escherichia coli significantly improved the resistance to heat. These results improve our understanding of these poorly-studied proteins and provide information for future studies on other proteins of unknown function.


We propose a probabilistic two-party communication complexity scenario with a prior nonmaximally entangled state, which results in less communication than that is required with only classical random correlations. A simple all-optical implementation of this protocol is presented and demonstrates our conclusion.


Given two CT thorax images from the same patient taken at two different points in time, a detailed follow-up assessment of pleural thickenings and their growth requires a registration of the regarded image regions. While the spatio-temporal matching of thickenings could be achieved by a rigid registration, the direct visual comparison or the combination of thickening segmentations from different points in time require a more precise registration. We present a new method which provides a non-rigid registration of the 3D image data in the region close to the lung surface, where pleural thickenings are located. A B-spline based approach is used to compensate the non-rigid deformations of the lungs. The control-grid for the B-splines is determined using a non-iterative method, which requires matched feature points from the registered image pair. However, current non-rigid registration methods compensate all changes of the lung surface. This is in our case explicitly undesired for changes caused by pleural thickenings. Therefore, our approach takes the thickenings into account by choosing feature points not directly located on the lung surface. The number of feature points is reduced and only strong features are kept for a 3D block matching.


Received: 1 May 2019 Accepted: 12 August 2019 The purpose of this research was to ensure that the leaves of multi-leaf collimator (MLC) move along the trajectory set in the radiotherapy plan. Aiming at the characteristics of multileaf control of multi-leaf collimator, the model of leaf control system is established. Taking the synchronized error between leaves as the input of the system, combined with PD CCC and PD ILC, an iterative learning control strategy based on cross-coupled is proposed, and verified by experiments, then compared with the multi-leaf control strategy that adopts iterative learning control algorithm independently. The experimental results show that the control strategy proposed in this study can reduce the synchronized error between leaves, and the initial value of the maximum absolute value of the error proposed reduces the synchronous position error of the leaves from the beginning, which meets the requirements of radiation therapy. The results provide a guarantee for the synchronous control of MLC to improve the efficiency of conformal radiotherapy.


Electron cyclotron emission (ECE) from thermal plasmas in the Alcator A tokamak for harmonics from 2nd through 5th and up to the 7th harmonic for nonthermal plasmas have been observed in the frequency range of 400–800 GHz using a sensitive, low‐noise submillimeter heterodyne receiver. The sensitivity of the receiver (∼10−20 W Hz−1) allowed for the measurement of 4th and 5th harmonic ECE from thermal plasmas with Te≊800 eV. The receiver was absolutely calibrated and its field of view was experimentally determined. A careful analysis has been made to relate the receiver calibration to the plasma‐emitting volume, taking into account radiation coherence time, wall reflections, polarization scrambling, window losses, and aperture restrictions.

Absorption parameters of copper for 500 kV electrons are measured by means of the dynamical theory of electron diffraction of two-beam approximation by analysing the images of thickness fringes photographed with the single-beam and the two-beam methods. A bent wedge-shaped crystal is observed in the two-beam image using both the primary and the reflected beams with a large aperture as well as in the bright-field and the dark-field images using a small aperture. The following values of the absorption parameters have been obtained ξ220/ξ'0=0.070±0.007 and ξ220/ξ'220=0.051±0.003 at a temperature of 300 K, and ξ220/ξ'0=0.053±0.004 and ξ220/ξ'220=0.042±0.003 at a temperature of 200 K. Many-beam effects on the images of thickness contour are considered.


The prevalence of rheumatic heart disease is still significant in Nepal, especially in rural areas. It is an important preventable cause of morbidity and mortality in children and young adults. Diagnosis of rheumatic heart disease and acute rheumatic fever is based on clinical, laboratory, and echocardiographic criteria. Diagnosis and management criteria need to be locally relevant and practical to our context for implementation at the national level. The Cardiac Society of Nepal initiated the development of consensus document with aim of providing a reasonable and practical format of diagnostic and management. We hope this document will be helpful for physicians, pediatricians and cardiologists of the country to diagnose and treat acute rheumatic fever and RHD.


PURPOSE
In external beam radiotherapy for head-and-neck cancer, the actual dose delivered to the patients could considerably deviate from the planned dose due to volumetric and anatomic variations. The purpose of this study was to investigate whether direct dose matrix mapping can be reliably used to monitor weekly dose changes when compared to recalculation method on weekly kilo-voltage CBCT images.

METHODS
Ten head-and-neck patients, each with a planning CT, a mid-term replanning CT, and seven weekly CBCTs, were selected for this study. Contours of tumor volumes and radiosensitive normal structures were deformed from the planning CT to the CBCTs using a commercial program. These deformed contours were validated using the same day CT and CBCT. The daily doses were obtained by two Methods: (1)mapping the planned dose matrix to the corresponding CBCTs after rigid image registration; (2)recalculating dose on the CBCT images with the same planning beam configurations. For a fair comparison, density override of the external contours was performed for both methods.

RESULTS
No significant dose differences were seen comparing the dose matrix mapping and recalculation methods for both the target and sensitive structures(p≫0.05). From both dose mapping and recalculation methods, the difference in D95 between the dose of the day and planned dose was observed for the PTV with 1.7 ± 2.2% variations. Although no significant changes in the mean dose were observed for the other sensitive organs, the mean dose of the parotid glands increased 14.1 ± 14.9% for the right parotid and 7.5 ± 9.8% for the left parotid.

CONCLUSION
Dose matrix mapping is an effective and practical method to monitor weekly dose changes for patients with HN cancer. With the deformed contours from the planning CT, both the dose matrix mapping and recalculation methods can provide quantitative dose analysis and physician guidance for decisions on the adaptive replanning.


It is generally known that the protoplasmic streaming is active in adult cells but is not conspicuous when the cell is young. Though the reason for this is not clear, it must be due either to the difference in the physico-chemical nature of the protoplasm in different developmental stages or to the difference in physical factors such as the size of the cell, the development of vacuoles, etc. In the present report, special reference has been made to the behavior of the protoplasmic motion when the cell is bound off into smaller fragments. The internodial and leaf cells of Chara Braunii and those of some unidentified species of Chara were also used as materials. The unusually large size of the cell which we used permitted us to perform the operation of binding off the cell, an operation which is impossible with ordinary adult plant cells. The rate of flow being sensitive to the change in temperature, in all the following experiments the cell was observed in a small water bath kept at 27'C and placed on the microscopic stage. I) The rate of flow in relation to the length and width of the cell The length of the internodial cells in nature varies from a few millimeters to 100 mm or so, the diameter being 0.2-0.4 mm, while the leaf cells are usually several millimeters long and 0.1-0.2 mm wide. The protoplasm in all the normal internodial cells having the diameter of about 0.3 mm flows nearly with the same velocity, namely 75μ per second, irrespective of the length of the cell. This situation can be demonstrated more clearly by a method applied by Linsbauer (199), in which the cell is bound with a hair or silk thread. As a result of such an operation the cell is divided, without serious injury into two or more fragments. Such a procedure seems not to affect the activities of the cell. Each fragment thus divided not only survives for long time, but can even grow, under suitable conditions. In this manner, we can make cell fragments of any size we want, even smaller in size than those produced naturally.

The Haiyuan fault zone,one of intensive deformational zones in the northeastern Tibetan Plateau,records the information about the northeastward growth of the Tibetan Plateau.On the basis of detailed structural measuring,we proposed the sequences of the Cenozoic paleo-stress fields and the tectonic evolution of the Haiyuan fault zone.Our studies show a five-stage tectonic evolution as follows.The first was the widespread development of the basins along the Haiyuan fault zone from the Eocene to the Miocene due to the NW SE extension;secondly,the Haiyuan fault zone was featured by right strike-slip activity in the late Miocene to the Pliocene controlled by the NNE SSW compression;thirdly,the fault intensively thrusted northeastward in the Late Pliocene to the Early Pleistocene owing to the NE SW compression,which resulted in the geomorphic formation;fourthly,Late Pleistocene basins occurred,caused by the NE SW extension;lastly,Haiyuan fault zone was marked by sinistral strike-slip movement since the later Late pleistocene,and some pull-part basins formed along the fault.The neotectonics of the Haiyuan fault zone will provide some new structural evidences for probing the northeastward extending of the Tibetan Plateau.


Decentralized services are increasingly being developed and their proper usage in different areas is being experimented with. Autonomous codes, which are also called smart contracts, can be developed with Integrated Development Environments (IDE). However, these tools lack live environment tests. The underlying blockchain technologies are also evolving and it is not easy to catch all the developments. There is a need for an easy-to-use interface by which the developers can see the results of their codes. Tubu-io decentralized application development workbench is developed to serve as an efficient way for the programmers to deploy smart contracts on the blockchain networks and interact with them easily. It can also be used for teaching decentralized application programming for junior blockchain developers on blockchain testbeds. Finally, it will have an effect in decreasing the development time and the costs of developing decentralized application projects.


Stimulation of muscarinic receptors by carbachol (CCh) in the circular smooth muscle of the guinea pig gastric antrum causes muscle contraction. In the present study, muscarinic receptor subtype controlling the muscle contraction in response to CCh was studied using putative muscarinic receptor antagonists. Isometric force of the isolated circular muscle strips was measured in an organ bath. CCh contracted the muscle in a dose-dependent way, and each of the three muscarinic receptor antagonists, 4-diphenylacetoxy- N-methylpeperdine methiodide (4-DAMP), methoctramine and pirenzepine shifted the concentration- response curves to the right without significantly reducing the maximum force. The affinities of the muscarinic antagonists obtained from Schild plot analysis were 10.15, 7.05 and 6.84 for 4-DAMP, methoctramine and pirenzepine, respectively. These results suggest that the mainly mediate the muscle contraction in response to CCh in guinea pig gastric antrum.


An intervention study was performed to investigate the effect of lower-limb training programs on knee muscle activation patterns and their potential to support the knee load during running and cutting manoeuvres. It is known that balance training can reduce ACL injury but the underlying mechanisms are unknown. The effects that strength training has on support for the knee joint during sporting manoeuvres are also not known. Analysis of activation levels and patterns of leg muscles during running, sidestepping and crossover-cutting manoeuvres prior to and following 12-week training programs revealed important results in terms of potential support of load on the ACL. Balance training increased co-contraction and supportive muscle activation patterns, as did the combination of machine and balance training to a lesser extent. The strength training programs tended to reduce co-contraction and were associated with changes which would lead to less stability of the knee during sporting manoeuvres. It is recommended that balance training should be implemented to reduce an athlete's risk of ACL injury.

AbstractA series of Mg–V alloys were produced by physical vapour deposition (PVD). Both c and a lattice parameters, as well as the c/a ratio, decreased with increasing vanadium content. The deposits were characterised by a strong basal texture. The solid solubility of vanadium in magnesium was extended to ∼ 17 wt-% V: Grain refinement occurred with increasing solute content. The solid solution breakup temperature decreased as the vanadium content in the alloys increased. Pure vanadium precipitated when solid solubility was not retained. A thin oxide layer of between 10 and 20 nm existed at the surfaces of the alloys and consisted predominantly of hydromagnesite at the outermost surface with Mg(OH)2 in an excess of MgO underneath. No evidence of vanadium oxide in the surface film was found. Magnesium oxide was also found to exist between the grains of the deposits, creating a graded metal/oxide interface.

Welcome to the final issue of Volume 3! We are pleased to receive quality submissions so that we can provide informative and thought-provoking articles. The first article is an invited submission on the topic of palliative sedation. Palliative sedation is the use of sedative medications to relieve extreme suffering. This makes the patient unaware and unconscious while the disease takes its course. Consistent with the principle of double effect, palliative sedation is not intended to cause death or shorten life. Higgins and Altilio provide essential information about this often controversial treatment option. They also challenge practitioners to utilize a multidimensional approach, with our interdisciplinary colleagues, to explore the use of palliative sedation for patients who believe this is the best option for them. Next, Payne reports on a new area of focus for end-of-life and palliative care: elder abuse. An audit of safeguarding adult cases identified palliative care cases that also involved institutional, physical, verbal, and financial abuse and neglect. Payne revealed that preexisting psychosocial difficulties in families exacerbated the stresses involved in caring for individuals at the end of life which may lead to abuse allegations. Social workers can contribute to accurate assessment of abusive situations and provide support for individuals and their caregivers. As the dramatic aging of the population continues, it is likely that an increase in abuse allegations among dying individuals will occur. The stresses that are inherent in providing care need both monitoring and support from helping professionals. In the second of our international entries, Woo and colleagues explore the experience of growth among Chinese widowers. This interesting qualitative study revealed that there may be positive outcomes after such a devastating loss. An optimistic outlook on life and learning was revealed as a buffer against widowers' sorrow.


The objective of this paper is to synthesise through the reviews of various innovative teaching methods and how they have influenced the practice of entrepreneurship education. The various methods identified are case studies, business plan creation, problem-solving, simulation and games, team based or group discussions, guest speaker, seminars, individual and group projects, role play and lectures with latter being teacher centred while all the former are student centred. It was however, established that no one method can be used solely on its own, hence, the need for collective adoption under a given circumstance. Practically, all trainers, instructors and educators in the entrepreneurship field need to focus both on the design and implementation of entrepreneurship teaching and course programs based on the various aspects in terms of the teaching model(s) being adopted from the perspectives of providing answers to the questions of the why (purposes of the learning), what (contents), how (methods and pedagogies), for whom (audiences, participants), and for which outcomes (assessment).There are no enough models to conceptually drive the curriculum design and teaching methods of entrepreneurship education.


The dissociative photoionization of molecular-beam cooled CH2CO in a region of ˜10–20 eV was investigated with photoionization mass spectrometry using a synchrotron radiation as the light source. Photoionization efficiency curves of CH2CO+ and of observed fragment ions CH2+, CHCO+, HCO+, C2O+, CO+, and C2H2+ were measured to determine their appearance energies. Relative branching ratios as a function of photon energy were determined. Energies for formation of these observed fragment ions and their neutral counterparts upon ionization of CH2CO are computed with the Gaussian-3 method. Dissociative photoionization channels associated with six observed fragment ions are proposed based on comparison of determined appearance energies and predicted energies. The principal dissociative processes are direct breaking of C=C and C-H bonds to form CH2+ + CO and CHCO+ + H, respectively; at greater energies, dissociation involving H migration takes place.

In recent years there has been a growing scholarly interest in the rural settlements located in the regions of Laconia and Messenia, commonly referred to as perioikic communities. Despite an existing partial consensus concerning the economic and military connections between the perioikic communities and the Spartan polis, the actual status of such settlements still remains a matter of considerable controversy. This paper adopts a semantic-lexicological approach in an attempt to outline the discursive connotations of the term perioikoi and its cognates as employed in the classical sources. Such analysis aims to contribute to the ongoing historiographical debates, many of which overlook the in situ occurrences of the term in the actual sources and its various connotations. The paper specifically explores the linguistic and semantic fields of the term perioikos and its cognates as first recorded in Herodotus' Histories.


This study combines observations from outcrop and drill core with an analysis of the hydrocarbon distribution in two mature oil and gas fields to document the factors controlling the existence of fault seals in the Tertiary sandstone-shale sequence of the Columbus Basin. Juxtaposition of reservoir sandstones against shale intervals across normal faults cannot explain the oil and gas distribution in this area, indicating that fault zones serve as the lateral seals for these hydrocarbon accumulations. The fault-zone seals for the largest hydrocarbon columns (50-200 m) consist of shale smears formed by ductile deformation of shale beds during fault slip. Empirical evidence suggests that these zones are spatially continuous only where the shale content of the section displace along a fault exceeds 25% (shale smear factor <=4). Pore-throat radn of these shale-smear fault zones, calculated from observed column heights, are in the 0.05-1 mm range, decreasing exponentially with depth. Fault segments that do not meet the criteria for development of a shale smear appear to be transmissible or can seal only small columns (<20 m). Such poorly sealing fault segments are comprised primarily of cataclastically deformed sandstone, which, based on laboratory test data, does not have small enough pore throats to serve as high-capacity capillary seals in this area. Two different modes of fault-sealed trap leakage during hydrocarbon migration can be defined. Where shale smears are discontinuous, such as where a sandstone body is partially juxtaposed against itself, column heights are cross-fault spillpoint limited and can be analyzed using fault-plane sections combined with mapping of shale-smear continuity. These traps are likely to preferentially spill high-density hydrocarbons once trap capacity is reached. In contrast, traps bounded by spatially continuous shale smears probably leak through the pore network of the fault-zone material at the top of the trap, thus favoring preferential movement of low-density hydrocarbons in a two-phase system. Maximum column height estimates for such traps can be calculated using capillary pressure relationshi s. Hydrocarbon migration through stratigraphic sections containing fault-sealed traps of these two types may result in geochemical fractionation and phase segregation, both of which are observed in the Columbus Basin fields.

This paper investigated the response of rotor system supported on Squeezed Film Damper (SFD) under acceleration. The nonlinear film force in SFD is represented on the basis of π film theory. Consider-ing the acceleration of rotor, the motion equations have been derived. A numerical method is applied to solve the ODEs. From simulation results, it can be seen that rotating acceleration will influence the transit response of the rotor. Dramatic changing in acceleration will cause swing of film force in SFD of rotor after a period of stable running.


The following is a philosophical consideration of the computer, particularly the graphical user interface (GUI), as a cultural artifact. Basing the examination on the premise that the computer is not a neutral tool but, rather, is an extension of the society creating it, I review potential pitfalls associated with the GUI. Particularly, the GUI can act to relegate computer literacy to a status of usability, rather than conceptual knowledge, and it can also function to further marginalize individuals outside the membership of the dominant culture. Our current notions of "computer literacy" must be revisited under the scrutiny of the computer, particularly the GUI, as a cultural artifact that acts to re-perpetuate the dominant culture's standards and mores. As instructors, we need to be aware of these inherent detrimental aspects so that we can empower our students to control the tool we call the computer, rather than vice versa. This paper seeks to raise questions and awareness of potential pitfalls and issues that we, as educators, need to address in our classrooms.


Introduction Spatial and temporal variations in animal populations can result from changes in the amount of suitable habitat, food availability or human disturbance.8 As one example, differences in Bald Eagle populations on Besnard and Nemeiben Lakes were due primarily to corresponding differences in prey (fish) populations.2 Tracking changes in bird populations can be useful in understanding changes in prey availability and habitat quality as well as in the birds themselves. It is in this context that we report results of boat surveys on Besnard Lake in 2003, 2004 and 2005, and compare the findings with observations made from 1976 to 1990.


Introduction.– Feasible tools for multidimensional geriatric screening in the emergency department (ED) are presently lacking. This study therefore evaluated the diagnostic value of a newly developed emergency geriatric screening (EGS) tool. Methods.– A brief EGS tool was developed based on a literature review for short screening tools of cognition, mobility, and activities of daily living (ADL), and recommended for the 795 patients aged≥75 years admitted to the ED at Bern University Hospital during an intervention period of 4 months. The 752 patients admitted during the 4months prior to this period served as control (pre-post design). Diagnoseswere classifiedbasedonEDdischarge reports. In patients transferred to subsequent inpatient hospital care (n=219), length of stay (LOS) was recorded. Results.– During the intervention period, EGS was performed in 338 of the 795 (42.5%) patients. Reasons for non-performancewere non-feasibility due to patient reason (n=194) and logistic reasons (n=263). The number of persons with abnormal screening result was 170 (50.3%) for cognition, 227 (67.2%) for mobility, and 195 (57.7%) for ADL. The number of personswith related diagnoseswas higher during the intervention period as compared to the control period (e.g., cognitive diagnoses in 15.8% as compared to 12.2% of all admitted patients, P=0.05). EGS findings predicted in-hospital LOS (time-ratio per increase of one limited domain 1.26, 95%CI 1.05–1.51, P=0.01). Key conclusions.– The introduction of a short, newly developed EGS resulted in a modest, but promising increase in the detection of potentially overlooked geriatric problems. Adaptationswithmethods to enhance feasibility (e.g., integration in a software system) and to ensure clinical benefit (e.g., management steps associated with abnormal findings) might lead to a successful and effective method of geriatric screening in emergency care.


The past few years research the positive definition of teacher competencies when the traditional values of face-to-face teaching are integrated with the best online learning practices, providing a flexible learning approach. The use of open resources in education addresses the core of teaching, learning and evaluation, restructuring the transfer of knowledge and skills from trainers to learners and the formation of the specific competencies for the teaching profession. It is necessary to redefine the educational technology by developing specific educational strategies for the training of teachers, strategies which will integrate the open resource system in the field of e-learning. In this context, it is inevitable to analyze the availability of the educational environment so that, from an ergonomic point of view, it should support the training of teaching staff competencies (didactic, digital, research, etc.) The paper focuses on the analysis of the evolution of the educational means system and on the identification of the resources used in teacher training, while analyzing their correlation with the characteristics of the target group (students enrolled in the pedagogy of pre-school and primary education). The study highlights the role of digital competences as a prerequisite for forming the other competences of the future teacher (didactic, research, classroom management, entrepreneurship, etc.), but also the premise of personal development in the continuous professional training system. The findings of the study may be arguments for restructuring the educational strategies and including the information and communication technology as an educational strategy in adult education.


Sciadia tenebraria auctorum from European high mountains was recently recognized to be a complex of several allopatric species. In this paper the group is revised anew on the basis of extended studies of collections and combined analysis of morphological and molecular traits. The habitus and male and female genitalia of all taxa are figured. Five species and two subspecies are recognized as valid. The name Geometra horridaria Hubner, 1799 is not available for that group, being a junior primary homonym. Two taxa, Sciadia sabaudiensis Leraut, 2008 and Geometra torvaria Hubner, 1813 are downgraded from species rank to the synonymy of Sciadia tenebraria (Esper, 1806). Sciadia innuptaria (Herrich-Schaffer, 1852) is raised from the synonymy of Sciadia tenebraria to species rank. One new species and one new subspecies are described: Sciadia dolomitica sp. nov. from the Dolomite mountains, South Tyrol, northern Italy; and Sciadia tenebraria taurusica ssp. nov. from Hohe Tauern mountains, East Tyrol, Austria. A lectotype is designated for Gnophos innuptaria Herrich-Schaffer, 1852, and neotypes are designated for Geometra tenebraria Esper, 1806 and Geometra torvaria Hubner, 1813.

ABSTRACT In the present investigation, the roughness characteristics of the gravel bed is tested and modelled for the no-load condition. A straight trapezoidal channel having gravel bed surface of grain size D50 as 13.5 mm for no-load condition is used to carry out the investigation. Depth averaged velocity (DAV) and boundary shear stress (BSS) have been measured for five different depths. An improved model for prediction of friction factor is derived as the function of corresponding hydraulic radius and average diameter of the gravel. This improved model is validated with the models of past investigators. Furthermore, BSS is then calculated using Shiono and Knight Method (SKM), which is dependent on the following hydraulic parameters, such as friction factor f, coefficient of eddy viscosity λ and secondary flow term Г. Since friction factor is modelled for the given channel, same model is used to calculate the value of f over the bed, which tests the reliability of the model while using numerical method. The lateral distribution of DAV and BSS is shown for five different flow depths, which elaborate the bed friction due to the no-load condition. Finally, friction factor model is corroborated on two reaches of the natural river.


Geological bodies of small buried depths, small sizes, and complex distribution are commonly needed to be located in engineering electric prospecting. Higher accuracy of detective methods is required. Using the 3-D high-density resistivity method, which is one of the normal methods in engineering prospecting, we can get plenty of data and detect the bodies in many bearings. A study of anomaly features in 3-D high-density E-SCAN resistivity survey was done in this paper. Several classical models are designed and calculated using the finite element method to study their anomalous features. The results show that the resolution of E-SCAN on low resistivity bodies is stronger than high resistivity bodies. Without setting power on all electrodes it can distinguish geologic body's electrical property and position. But it is difficult to identify downward extention of geological bodies by the measurements.


 Abstract — Irritable bowel syndrome (IBS) is a gastrointestinal disorder characterized by an alteration in bowel movements. There are three different types of IBS: diarrhea-predominant IBS (IBS-D), constipation-predominant IBS (IBS-C) and IBS with mixed bowel habit (IBS-M). Antimicrobials are increasingly being used as treatment for all types of IBS. Due to this increased use and subsequent success, the gut microbiome as a factor in the etiology of IBS is becoming more apparent. Accepted standard treatment has focused on IBS-C and involves either vancomycin or rifaximin. Here, we report on a cohort of 18 patients treated with both vancomycin and rifaximin for IBS-D. These patients' records were reviewed retrospectively. In this cohort, patients were aged between 24-74 years (mean 44 years) and nine were female. At baseline all patients had diarrhea, four with mucus and one with blood. Other reported symptoms include abdominal pain (n = 11) bloating (n = 9), flatulence (n = 7), fatigue (n = 4) and nausea (n = 3). Patient's treatments were personalized according to their symptom severity and tolerability and were treated with a combination of rifaximin (500-3000 mg/d) and vancomycin (500 mg-1500 mg/d) for an ongoing period. Follow-ups were conducted between 2-32 weeks. Of all patients, 89% reported improvement of at least 1 symptom, one reported no change and one patient's symptoms got worse. The success of this combination treatment could be due to the different mechanisms of action undertaken by each medication. Vancomycin works by inhibiting the cell wall of the bacteria and rifaximin by inhibiting protein synthesis. This success in treatment validates the idea that IBS-D may be driven by a bacterial infection of the gastrointestinal microbiome. As IBS-D presents similarly to Clostridium difficile and symptom improvement can occur with the same treatment as Clostridium difficile of rifaximin and vancomycin, there is reason to suggest that the infectious agent could be an unidentified strain of Clostridium . Although these results offer some validity to the theory, more research is required.

Three alkylenedithio derivatives of 1,3-bis(1,3-dithiol-2-ylidene)-1,3-dihydrobenzo[c]thiophene (BDTBT) have been synthesized. These donors exhibited an electron-donating ability near to that of tetrathiafulvalene and afforded a very stable radical cation. The powdered tetracyanoquinodimethane complex of the methylenedithio derivative exhibited a fairly high room temperature conductivity of σ = 15 Scm−1 and a semiconducting behavior with a very low activation energy of Ea = 0.050 eV.


There is a large amount of research in finance which addresses whether equity markets are underor overvalued by using what is called the Gordon growth model. These papers essentially compute a dividend discount model; they argue bitterly over definitions of dividends, earnings, free cash flows, buy backs and so forth. They have concluded (recently) that equity markets have been overvalued and are hence likely to fall. This analysis can be criticized for a number of reasons, the most important being, as far as we are concerned, that it fails to ask the important question, how long will the fall last? These models analyse long-run equilibrium, but give no information about the dynamics of prices away from that equilibrium. The contribution by Sornette and Zhou provides a methodology which gives some insight into the behaviour of a market after a large bubble, and thus addresses inter-equilibria behaviour. This period is referred to by the authors as an anti-bubble (second paragraph of the introduction), which is characterized by a sequence of local minima and maxima (first paragraph of section 2.3). The authors apply the idea of discrete scale invariance which could be justified by the interaction of agents at different hierarchies. This is reminiscent of Adam Smith's (1776) idea that individuals pursuing their own interest lead to self-organized systems. Discrete scale invariance can be characterized by relations of the following form: f(x) = (l/fi)f(Xx), for some function / , and /z, A, > 0 in some subset of the rationals (i.e. the relation only holds for/.i and X taking some countable values). As a result of the countable values restriction, discrete scale invariance is characterized by the existence of a periodic pattern with changing amplitudes. This pattern characterizes the agony of a bubble. The Landau expansion is obtained by retaining a few terms of the solution of the above equation around the critical point. Therefore, the expansion becomes less reliable as we move away from the critical point. This clearly restricts the approach to the study of a finite time span after the crash, unless an increasing number of terms is retained. Consequently, this allows us to interpret the dynamics of a market after its critical point (closely related to the time of a crash), but not necessarily before that. In fact, the power acceleration in the market prices does not necessarily imply a crash. Indeed, the authors draw a distinction between the Russian market prior to and after the speculative peak in 1997 and other cases, i.e. Nikkei. Therefore, we find the analysis using this approach to be purely deterministic and, as a consequence of this, it may not tell us the whole story. Basically, the use of some further explanatory variable which is not necessarily previsible ((Xn)n e ^ is Tn previsible if Xn is Tn ~\ measurable, where {Tn )n €^ is some suitable filtration), but measurable (with respect to some suitable filtration) could be used to complement their study. In particular, volumes should be a fundamental explanatory variable for the development and 'agony' of a crash. Intuitively, price volatility without trade typically creates less economic hardship, as losses are not realized. This usually results because agents have sufficient wealth to avoid forced sales. The joint distribution of prices and volumes should tell us more about the anatomy of a crisis. Overall, the paper provides an explanation of the cause of a crash and the subsequent dynamics. This could have tremendous value for forecasting and risk management during particularly turbulent periods. But to do so, we need to gain a better understanding of the applicability of the idea of discrete scale invariance. As the authors note, not all crashes are the same, and a theory that could discriminate among them ex ante seems to be lacking. The techniques described in the paper are novel, and of interest to many econometricians. This paper is clearly of great value as more standard techniques would not be applicable in the framework analysed by the authors. In making several of their claims and comparing the US markets with Japan, the authors rely heavily on visual inspection. While the results are convincing (and shown to be formally significant under appropriate, but unstated assumptions) there could still be some need for more formal financial econometric testing at least from the point of view of a financial economist. For example, the authors briefly state the asymptotic distribution of the log-likelihood ratio statistic, which is well known, but do not mention the statistical properties of their unusual (for economists) frequency domain estimators (e.g. the LorruVs periodogram is exponentially distributed under the underlying assumption of normality; see Scargle (1982) for further details).


Caching approximate values instead of exact values presents an opportunity for performance gains in exchange for decreased precision. To maximize the performance improvement, cached approximations must be of appropriate precision: approximations that are too precise easily become invalid, requiring frequent refreshing, while overly imprecise approximations are likely to be useless to applications, which must then bypass the cache. We present a parameterized algorithm for adjusting the precision of cached approximations adaptively to achieve the best performance as data values, precision requirements, or workload vary. We consider interval approximations to numeric values but our ideas can be extended to other kinds of data and approximations. Our algorithm strictly generalizes previous adaptive caching algorithms for exact copies: we can set parameters to require that all approximations be exact, in which case our algorithm dynamically chooses whether or not to cache each data value.
We have implemented our algorithm and tested it on synthetic and real-world data. A number of experimental results are reported, showing the effectiveness of our algorithm at maximizing performance, and also showing that in the special case of exact caching our algorithm performs as well as previous algorithms. In cases where bounded imprecision is acceptable, our algorithm easily outperforms previous algorithms for exact caching.


It is our pleasure to present the proceedings of the ACM Symposium on Applied Perception (ACM SAP) held in Anaheim California and co-located with SIGGRAPH 2016.

The scope of the conference includes applications and algorithms in any area of research that incorporates elements of perception and computer science. In keeping with the multidisciplinary theme of the conference, we are excited to welcome Laurent Itti and Allison Okamura, outstanding researchers with expertise in computer science, neuroscience, and haptics, as the SAP 2016 keynote speakers.


Transmission of electromagnetic waves propagating in planar, cylindrical, and spherical single dielectric layer, double‐barrier resonant tunneling and multiple period Bragg reflector systems have been systematically studied by the transfer matrix method. Interesting features are found in the transmission spectra of the systems with cylindrical and spherical geometries, due to the coherence of the propagation waves in these systems. In particular, an increase of the resolution power (sharper transmission peaks) in the double‐barrier resonant tunneling system is demonstrated in the cylindrical and spherical structures compared to that of the planar structure. Universal behavior, that the transmission at zero frequency limit decreases substantially as the propagation wave changes from plane to cylindrical wave and to spherical wave, has been shown in the spectra of these systems. Potential applications in reducing the radiation energy loss for transferring large density alternative current are discussed.


This paper presents the convincing arguments for going with on-board environmental data platform-satellite communications following three years of successful data acquisition using data link. In addition, the rationale for the selection of the Geostationary Orbiting Environmental Satellite (GOES) System approach to hardware procurement and implementation on-board environmental data buoys is also given. Finally, the paper will provide a wide expanse of data results indicating percentage communication successes from various geographical buoy locations.


Converging evidence indicates that response inhibition may arise from the interaction of effortful proactive and reflexive reactive mechanisms. However, the distinction between the neural basis sustaining proactive and reactive inhibitory processes is still unclear. To identify reliable neural markers of proactive inhibition, we examined the behavioral and electrophysiological correlates elicited by manipulating the degree of inhibitory control in a task that involved the detection and amendment of errors. Restraining or encouraging the correction of errors did not affect the time course of the behavioral and neural correlates associated to reactive inhibition. We rather found that a bilateral and sustained decrease of corticomotor excitability was required for an effective proactive inhibitory control, whereas selective strategies were associated with defective response suppression. Our results provide behavioral and electrophysiological conclusive evidence of a comprehensive proactive inhibitory mechanism, with a distinctive underlying neural basis, governing the commission and amendment of errors. Together, these findings hint at a decisive role for changes in corticomotor excitability in determining whether an action will be successfully suppressed. SIGNIFICANCE STATEMENT Response inhibition is a fundamental brain function that must be flexible enough to incorporate volitional goal-directed demands, along with rapid, automatic and well consolidated behaviors. Previous studies reflect a lack of consensus regarding the neural correlates subserving these two –proactive and reactive– distinct modes of inhibitory control. We combined electrophysiological recordings with behavioral measures within a paradigm of detection and correction of errors under two degrees of inhibitory control to identify genuine neural markers of proactive inhibitory control. We found evidence supporting a sustained and global –not selective– reduction of corticomotor excitability subserving successful proactive inhibition of motor responses. Our findings favor a distinctive mechanism of comprehensive inhibitory control to amend errors under a high degree of response competition.


The methods for feature extraction in eddy current signal processing and the applications of neural network and data fusion to signal classification, identification and evaluation are described. The trend of inverse problem solution and the choice of signal processing method according to signal characteristics in eddy current testing are also discussed.


c-Jun N-terminal kinase 3α1 (JNK3α1) is a mitogen-activated protein kinase family member expressed primarily in the brain that phosphorylates protein transcription factors, including c-Jun and activating transcription factor-2 (ATF-2) upon activation by a variety of stress-based stimuli. In this study, we set out to design JNK3-selective inhibitors that had >1000-fold selectivity over p38, another closely related mitogen-activated protein kinase family member. To do this we employed traditional medicinal chemistry principles coupled with structure-based drug design. Inhibitors from the aminopyrazole class, such as SR-3576, were found to be very potent JNK3 inhibitors (IC50 = 7 nm) with >2800-fold selectivity over p38 (p38 IC50 > 20 μm) and had cell-based potency of ∼1 μm. In contrast, indazole-based inhibitors exemplified by SR-3737 were potent inhibitors of both JNK3 (IC50 = 12 nm) and p38 (IC50 = 3 nm). These selectivity differences between the indazole class and the aminopyrazole class came despite nearly identical binding (root mean square deviation = 0.33 Å) of these two compound classes to JNK3. The structural features within the compounds giving rise to the selectivity in the aminopyrazole class include the highly planar nature of the pyrazole, N-linked phenyl structures, which better occupied the smaller active site of JNK3 compared with the larger active site of p38.


The physical activity must be performed under certain parameters to achieve health benefits. The adults must meet at least 30 minutes of physical activity of moderate to vigorous intensity, 5 or more times per week. The aims in this paper are focused in determinate if the object people of the research achieve with the recommendations of healthy physical practice. Also to examine if there are differences between the levels of physical activity according to the gender, age and level of studies of the habitants of Monterrey city (Mexico). A transversal study is presented. The sample comprised 1,008 individuals of 15 years old or older (498 male= 49.4% and 510 female= 50.6%; M=36.57; SD=17.05, Range=15-87). Results reveal an extreme worrying situation about the physical activity practice. Only a quarter of the whole sample (26%) achieve with the minimal lineaments to receive the healthy benefits of the physical activity. In counterpart, the rest of the participants (74%) mentioned being inactive or having low level of physical activities, insufficient to get healthy effects.


Nationwide surveys of hereditary platelet function disorders in Japan were carried out in 1976, 1981, and 1986. Information on 271 cases received in the 1986 survey was analyzed with that for 103 other cases reported in earlier surveys but not in 1986, making a total of 374 cases. The mortality rate was 6.8% of 162 cases in 1976, 6.6% of 213 cases in 1981, and 5.9% of 374 cases in 1986. Bleeding symptoms appeared at age 12 years in 56.8% of patients and the most common were epistaxis and purpura. Of the 295 cases 49.5% were isolated cases, 20.3% had siblings with confirmed bleeding tendencies, and 30.2% had other kin with bleeding tendencies, suggestings autosomal tnansmission. Consanguineous marriage was reported by 11.9% of patients. Of the 374 cases in 1986, 59.4% were thrombasthenia (TA), 11.5% Bernard-Soulier symdrome (BSS), 22.5% release abnormalities (PRA), 1.3% other, and 5.3% unclassified. Of the 84 cases of PRA, 60 were storage pool deficiency, 18 release mechanism abnormalities, and 6 undecided between the two types. The resultsof laboratory tests were as follows .


In recent years,oral English learning and teaching has been emphasized and many new teaching approaches have been adopted,but the effect is not good enough.In this study,oral tests will be taken to measure the oral English proficiency of non-English majors with the assistance of SPSS.By the comparative analysis of traditional teaching approach and the innovative one,it is expected to find relevant factors and facilitate the development of English teaching and learning.


Cardiovascular disease is the major contributor to both morbidity and mortality among US women and men, but the absolute numbers of women living with and dying from cardiovascular disease (CVD) and stroke are greater than for men [1]. A stunning advance in the past decade has been the decline by almost half in total CVD mortality for women, ascribed to improved control of major cardiovascular risk factors and improved management of established CVD, including secondary prevention. Concomitant, with this mortality decline, has been the near doubling of awareness of CVD as the major health problem for women; the heightened awareness resulted from initiatives of the National Heart, Lung, and Blood Institute (Heart Truth Campaign) and the American Heart Association (Red Dress Campaign). A new challenge is the increase in coronary heart disease (CHD) mortality among young women, 35 to 44 years of age [2], mandating increased CHD preventive efforts at younger age. Although women remain underrepresented in clinical trials of cardiovascular therapies [3], transformation of the research arena and results of recent landmark clinical trials arguably contributed to improvements in CHD care for women. Even with recognition of gender differences in CHD burden, women are not a homogenous group. As an example, age-adjusted CHD mortality is 122 per 100,000 black women versus 94 per 100,000 white women. Hypertension, more common among black women, is currently increasing in prevalence, accounting for mortality of 37 per 100,000 black compared with 14 per 100,000 white women [1].


Semen was collected by means of artificial vaginae from a number of animal species housed at the Animal Research Station. Boar semen was immediately strained through layers of muslin to remove any gel present. The gel-free fluid was then centrifuged at 5° C and the sperm-free seminal plasma supernate used immediately or stored at —20° C until required. Spermatozoa were prepared from fresh semen by centrifuging and washing with 'Sperm Ringer' solution (Mann, 1964, p. 347). Boar vesicular secretion was obtained from freshly excised seminal vesicles by expressing the fluids after dissection of the organ. Boar epididymal semen was obtained from freshly excised epididymides, following the method ofLasley & Bogart (1944) as described by Walton (1956). The epididymal seminal plasma was obtained by centrifuging the epididymal


Change detection (CD) and extraction (EXTN) of buildings based on convolutional neural networks (CNNs) have made encouraging progress in the remote sensing community. Although these two tasks are different in objective and application scenarios, both focus on building objects. However, previous methods were accustomed to considering these two tasks separately, and the CD task suffered from the precondition that bitemporal labeled images were used as paired supervision signals. In this study, we propose a stable prototype-guided single-temporal supervised learning framework (PGLF) as a joint solution for building CD and cross-temporal EXTN by exploring two cores: knowledge commonality and task specificity. For knowledge commonality, we introduced a mulon module (MPRM) to generate stable building prototypes from support foreground features and designed a prototype to query feature adaptive fusion (PQAF) module to suppress background noise and extract discriminative building features in a way that support prototype-guided query feature enhancement. For task specificity, we designed a multiscale spatiotemporal interaction module (MSTI) to capture bidirectional change features with strong spatiotemporal correlations. Besides, we developed a pseudo bitemporal image pair construction method to improve the performance of building CD and cross-temporal EXTN under single-temporal supervision signals. PGLF was trained on pseudo bitemporal labeled image pairs and tested on the public aerial WHU building dataset and proposed the satellite SPO building dataset. The comprehensive experimental results demonstrate the superiority of the proposed method.

Speech recognition systems for conversational telephone speech require the audio data to be automatically divided into regions of speech and non-speech. The quality of this audio segmentation affects the recognition accuracy. This paper describes several approaches to segmentation and compares the resulting recogniser performance. It is shown that using Gaussian mixture models outperforms an energy-detection method and using the output from the speech recogniser itself increases performance further. An upper bound on possible performance was obtained when deriving a segmentation from a forced alignment of the reference words and this outperformed using manually marked word times. Finally the correlation between an appropriately defined segmentation score and WER is shown to be over 0.95 across three data sets, suggesting that segmentations can be evaluated directly without the need for full decoding runs.

Plasma etching of ultrathin layers of high-k materials is one critical step in the fabrication of gate transistors. The main challenge in this process is to achieve an infinite etching selectively between the high-k and the Si (or SiO2 covered silicon) substrate to prevent damaging the source and drain regions of the transistor. State of the art high-k etching plasmas use BCl3 chemistries, sometime at high wafer temperature. However, the process window in which an infinite high-k/Si selectivity can be achieved is very narrow and several issues remain associated with these processes. In this work, we introduced a new high-k plasma etching chemistry: SiCl4/Cl2. It can be used to etch Hf-based and Al-based high-k materials with an infinite selectivity towards Si, SiO2 and SiON, and with a much wider process window than BCl3 plasmas. XPS analyses indicate that the selectivity mechanism relies on the formation of a SiClx deposit selectively on Si-containing materials, which prevent them from being etched. By c...


The purpose of this study was to study the modeling of the osmo-convetive drying kinetic and determine the effective mass diffusivity coefficient of Persimmon (Diospyros kaki cv. Fuyu) fruits. The fruit was subjected to osmo-convective drying at three different temperatures (50, 55, and 60C) and 10 different thin-layer semiempirical mathematical models were adjusted to experimental data. Then, according to the highest correlation coefficient (R2) and the least χ2 analysis the attained results showed the Midilli's model as the best option to describe the experimental data at the studied temperatures. In addition, the effective mass diffusivity coefficients were 1.04 × 10−6, 1.40 × 10−6, and 8.27 × 10−7 m2/s at 50, 55, and 60C, respectively. These results can be interesting to food data collection, drying equipment design and to support technical research in food process simulation.

Practical Applications
The osmo-convective drying process is widely used for foods dried production or with reduced water content. In fact, the post-harvest losses can be avoided, since that dried persimmon by osmo-convective drying, exhibit a good quality and extended shelf-life. Thus, the application of mathematical models to describe experimental data of this drying process achieves great practical importance because the number of laboratory tests can be reduced and it makes possible to obtain important parameters such as drying time, mass diffusion coefficient, among others, necessary to conception of processes and dryers.

Received: 25 March 2021 Accepted: 15 April 2021 The objective of this study was to assess the seismic performance of two types of bridges structures under effect of earthquake by using different locations and numbers of piers. The results of D/C ratio showed that simply supported I girder bridge appeared higher structural capacity than continuous box girder bridge which was resisted the seismic demand. Continuous box girder bridge had higher seismic demand and lower structural capacity comparing with simply supported I girder bridge. Commonly, the seismic design for two types of bridges models with increasing of piers numbers was suitable to resist the earthquake action for region type B. The results of non-linear static analysis (pushover method) showed that the increasing of piers numbers had significant effects on the seismic design of bridges structures to increase the displacement capacity, force capacity, and decreasing of seismic demand to reduce the effects of earthquake action on the bridges structural members. The bridge type simply supported I girder had higher capacity in longitudinal direction than continuous box girder bridge. Whereas, for continuous box girder bridge appeared higher capacity in transverse direction than simply supported I girder. The performance points which were based on displacement were decreased with increasing the piers numbers for bridges structures supports.


Cloud computing is being adopted more and more in recent years. It offers several benefits, such as high elasticity, availability and cost reduction, but yet presents some issues. Among the most important, the potential lack of security can affect the spreading of this technology. As cloud computing is pushing forward to the digital era, where users can have their own digital identity to access restricted resources or services, a reliable authentication and authorization system would attract more users to get involved in such process. This paper proposes an integration of the VOMS (Virtual Organization Membership Service) system for authorization and SPID (Sistema Pubblico per la gestione dell'Identità Digitale) system for authentication, within Cloud Foundry PaaS (Platform as a Service) model. Considerations, differences and interoperability matters will be addressed in order to provide a comprehensive scheme.


A continuous sampling plan, CSP‐SUM, is proposed based on the use of sums of run‐lengths of conforming items for deciding when to switch between the phases of sampling inspection and 100% inspection. The conventional measures of performance of CSPs such as the average outgoing quality, average fraction inspected, and the proportion passed under sampling inspection are evaluated for CSP‐SUM. Using these and other measures, comparisons with some standard CSPs are provided and indicate better performance for CSP‐SUM. Comparisons are also made with a recently‐proposed CSP utilizing CUSUMs, termed CSP‐CUSUM, and indicate that the performance of CSP‐SUM can be close to that of CSP‐CUSUM. A table is provided to aid the choice of parameters for the operation of CSP‐SUM. It is recommended that a conforming run‐length control chart be maintained in parallel with CSP‐SUM to detect significant upward shifts in the fraction defective of the process.

The polymerization of 4-methyl-1,3-dioxepane (1a), 2,4-dimethyl-1,3-dioxepane (1b), and 4,4-dimethyl-1,3-dioxepane (1c) was investigated in 1,2-dichloroethane at different temperatures ranging from −60 to 0°C by using boron trifluoride etherate as initiator. The polymerization of 1a involves an equilibrium between monomer and polymer, and gives a viscous polymer along with some cyclic oligomers of different sizes. 1H NMR and 13C NMR analysis of the polymer revealed that the bond cleavage of the unsymmetrical 1,3-dioxepane ring in the polymerization occurred nearly randomly at the two acetal CO bonds. The thermodynamic parameters for the polymerization were determined from the temperature dependence of the equilibrium monomer concentrations: ΔH=−9,3±1,3 kJ · mol−1 and ΔS=−38,8±7,8J · mol−1 · K−1. Dimethyl substituted 1,3-dioxepanes were found to be very reluctant to polymerize: Only a liquid oligomer was formed in very low yield from 1b, and even oligomer was not obtained from 1c. The effect of methyl substituents on the cationic polymerizability of 1,3-dioxepanes is discussed from the thermodynamic point of view.


Medical imaging uses the advantage of digital technology in imaging and teleradiology. In teleradiology systems large amount of data is acquired, stored and transmitted. A major technology that may help to solve the problems associated with the massive data storage and data transfer capacity is data compression and decompression. There are many methods of image compression available. They are classified as lossless and lossy compression methods. In lossy compression method the decompressed image contains some distortion. Fractal image compression (FIC) is a lossy compression method. In fractal image compression an image is coded as a set of contractive transformations in a complete metric space. The set of contractive transformations is guaranteed to produce an approximation to the original image. In this paper FIC is achieved by PIFS using quadtree partitioning. PIFS is applied on different images like , Ultrasound, CT Scan, Angiogram, X-ray, Mammograms. In each modality approximately twenty images are considered and the average values of compression ratio and PSNR values are arrived. In this method of fractal encoding, the parameter, tolerance factor Tmax, is varied from 1 to 10, keeping the other standard parameters constant. For all modalities of images the compression ratio and Peak Signal to Noise Ratio (PSNR) are computed and studied. The quality of the decompressed image is arrived by PSNR values. From the results it is observed that the compression ratio increases with the tolerance factor and mammogram has the highest compression ratio. The quality of the image is not degraded upto an optimum value of tolerance factor, Tmax, equal to 8, because of the properties of fractal compression. Keywords—Fractal image compression, IFS, PIFS, PSNR, Quadtree partitioning.

The purpose of this paper is to describe how the actions linked to pedagogic work are defined and negotiated in relation with the social and normative context in primary schools located in Buenos Aires City. The definition of School Effectiveness and its associated factors provided the framework for the design as well as for the interpretation of the findings. The subject was approached from a micro-social angle, focusing on school work and its actors point of view. In order to do so, a deliberate sample provided the elements to compare four primary schools from Buenos Aires City. The data was obtained by utilizing a variety of methods. To synthesize the information the four schools were placed on a continuum which defines their levels of efficiency and shows how on each of its extremes social and normative peculiarities are compressed. The differences among schools materialize in the environmental conditions in which school life takes place, family participation and the different levels of pedagogic hegemony. The research is relevant to the field of school management as it helps to understand which conditions favour or hinder the school centralization around the teaching process in different contexts.

The prediction model of propagation life of oblique crack on rail′s surface was established by the fracture mechanics theory.Taking CRH2 train-set as research object,stress distribution in the internal of rail when wheel and rail contacted was calculated,and then the propogation life of oblique crack on rail surface was estimated by using above modle.Furthermore,the effects of friction factor,inclination angle and wear rate on the propagation life of rail surface oblique crack were analyzed.The results show that the oblique crack propagation life decreased with the increase of friction factor when the inclination was 30°-40°,and the oblique crack propagation life first increased then decreased when the inclination angle was 50°-60°.With the increase of inclination angles,the oblique crack propagation life increased,then decreased.The oblique crack propagation life increased slowly with the increase of wear rate,and then increased rapidly when the wear rate up to a constant value.Fact data could prove indirectly the accurate of prediction.
