The extracellular matrix provides both chemical and physical cues that control cellular processes such as migration, division, differentiation, and cancer progression. Cells can mechanically alter the matrix by applying forces that result in matrix displacements, which in turn may localize to form dense bands along which cells may migrate. To quantify the displacements, we use confocal microscopy and fluorescent labeling to acquire high-contrast images of the fibrous material. Using a technique for quantitative image analysis called digital volume correlation, we then compute the matrix displacements. Our experimental technology offers a means to quantify matrix mechanics and cell-matrix interactions. We are now using these experimental tools to modulate mechanical properties of the matrix to study cell contraction and migration.

Background: Growth hormone and insulin-like growth factor 1 are anabolic hormones that play a vital role in the growth of various physical organs. Exercise is one of the stimuli that affect GH and IGF-1 secretion. Objectives: This study aimed to compare the effect of two types of high-intensity interval training (HIIT) on plasma levels of GH and IGF-l in overweight nurses. Methods: In this study, 27 nurses were voluntarily selected and randomly assigned to three groups (9 participants for each group): 1. HIIT (type 1), including eight seconds of spring running and 12 seconds of active recovery, 2. HIIT (type 2), including a 40-meter shuttle run with maximum speed, 3. control. HIIT (type 1) was performed for four weeks, three sessions per week, each session 6 - 9 min with more than 90% HRmax. HIIT (type 2) was applied for four weeks, three sessions per week, with more than 90% HRmax. The control group did not participate in any training protocol. The serum value of GH and IGF-1 were compared in three groups. The data were analyzed by the dependent t-test and ANOVA. One-way analysis of variance (ANOVA) was used to analyze the intergroup data at P ⟨ 0.05. Results: The results showed that HIIT (type 1) and (type 2) significantly increased plasma GH (P = 0.032 in group 2 and P = 0.010 in group 1) and IGF-l (P = 0.004 in group 2 and P = 10.013 in group 1) levels in nurses. The results showed a significant difference in the variables (GH and IGF-l) among HIIT (type 1), HIIT (type 2), and control groups. Conclusions: It can be concluded that four weeks of adverse intermittent exercises are effective in increasing the concentration of GH and IGF-1 serum and decreased percentage body fat in young nurses with overweight, and proportional to the intensity of the exercise protocol response rate is different.


Background: Neurocognitive models of autism suggest that starting a treatment at a younger age might be a critical factor in promoting optimal outcomes. The aim of the study is to examine the relationship between age at start of treatment and outcomes in a group of children with Autism Spectrum Disorders (ASDs) in Italy. Methods: Thirty-nine children between 22 and 77 months of age diagnosed with ASDs were divided into two groups on the basis of their age at start of a community-based behavioral treatment. Measures of severity of symptoms, cognitive abilities and adaptive functioning were collected at the beginning of the treatment (Time 1) and one year after (Time 2) to examine group differences in treatment outcomes. Our working hypothesis was that children who started the treatment at a younger age would show a more positive response to treatment compared to children who started at later age. Results: Compared with children who received a diagnosis and started the treatment at a later age, children in the early treatment group showed a better outcome in terms of attenuation of symptoms severity. No group differences were found in terms of adaptive functioning and cognitive abilities, with both groups equally improving their performance. Conclusions: Age at start of the treatment seems to be an important factor to promote gains in the social communication domain. However, gains in adaptive functioning and cognitive skills in our sample were not related to age. The positive effect of a community-based intervention in children with an early diagnosis of ASDs might be due to the plasticity of neural systems in age-dependent stages. The possibility that early intervention could substantially alter the course of behavioral and brain development in children with autism points to the urgent need for more research on treatment in this population.

Abstract Air-source heat pumps are widely used in winter as heating units due to their higher efficiency compared to electronicheaters or gas fired equipment. However, the air-source heat pump can cause discomfort during periodic defrosting operations.In this study, a PCM unit for continuous heating was adopted to solve this problem. The PCM unit consisted of a PCM,a heat exchanger, and control valves. It was installed between the outdoor and indoor units. The performance of the proposedsystem was measured during both defrosting and heating operations. The indoor unit showed an average leaving temperatureof 26 ℃ after adopting the PCM unit for continuous heating during the defrosting operation. Key words PCM(상변화물질), Defrosting(제상), Continuous heating(연속난방)†Corresponding author, E-mail: email@example.com 기호설명 CMM : 풍량 [m 3 /min] COP : 성능계수(Coefficient of performance) EEV : 전자팽창밸브 h : 엔탈피 [kJ/kg] IDU : 실내기(Indoor unit) m : 질량유량 [kg/h] ODU : 실외기(Outdoor unit) PCM : 상변화 물질(Phase change material)

Background and Objective: The supplementation in diet of chicken improves the amino acid balance and consequently increases protein synthesis and decreases fat synthesis. And the positive effects on meat quality. Essential elements are very necessary for the physiological functions of the human body and should be available through dietary intake, which supports regulation of cellular function, growth and maintenance of the body. The study provides original analytical data on the levels of zinc and methionine (ZeMet) in chicken meat (female) which are commonly consumed in Iraq. A total of three hundred and sixty (n = 360) of broiler chicks were weighed and classified in 3 groups, 0% ZnMet (Control T1), 0.5 gm/kg ZnMet (T2), 1 gm/kg ZnMet (T3).C arcass cuts (Breast, Whole Thigh, Wings, Back and Neck), Physical dissection (Lean, bone and skin), chemical analysis (moisture, protein, fat and ash), Cooking Loss, Drip Loss, TBA, PV and sensory evaluation (tenderness, juiciness, flavor, overall acceptance, acceptability, texture and general appearance) were steady. There were no significant differences between treatment in Carcass cuts (Breast, Back and Neck), Physical dissection (Lean, bone and skin), chemical analysis (moisture, protein, fat and ash), Cooking Loss, Drip Loss, TBA, PV. While there were a significant difference (P > 0.05) in Whole Thigh, Wings and sensory evaluation. The supplementation zinc and methionine (ZeMet) in diet of chicken improves the sensory evaluation of meat.


The consensus around the need for a shift in river management approaches to include more natural processes is steadily growing amongst scientists, practitioners, and governmental agencies. The freedom space for rivers concept promotes the delineation of a single space that integrates multiple fluvial dynamics such as floods, lateral migration, channel avulsions, and riparian wetlands connectivity. The objective of this research is to assess the validity of the hydrogeomorphological approach to delineate the freedom space for an extensive sampling of river reaches, covering 167 km, in contrasting watersheds in Quebec (Canada). Comparative analysis was conducted on the relative importance of erosion and flood processes on the freedom space delineation for various fluvial types. Semiautomated tools based on light detection and ranging (LiDAR) digital elevation models were also tested on an additional 274 km of watercourses to facilitate freedom space mapping over extensive zones and for highly dynamics environments such as alluvial fans. In the studied reaches, flood and erosion processes occur respectively, on average, in a space equivalent to 2.6 and 20.6 channel widths. In unconfined landscapes, flood processes represent an area up to almost four times the area of erosion processes expected in a 50‐year period. In partly confined and confined environments, erosion processes are more likely to exceed flooding zone, and therefore need to be integrated in the mapping. This study helps better determine the conditions for which the full methodology of freedom space mapping is required or where semiautomated methods can be used. It provides useful guidelines for the implementation of the freedom space approach.


Image inpainting is a skill developed to recover the damage part of an images. Many researches states that application wise there are various plausible techniques implemented for an image inpainting. By using artificial intelligence here image inpainting is executed. Image inpainting utilizes the contextual attention to fill pixel wise missing region of an image, missing region filling is done by deeply understanding of available known context. Partial convolution plays an important role to reconstruct an image for matching with the realistic images with structures and textures. The work starts with applying various masks on the image and then reconstruction of an image form by applying partial convolution layer. The main difference of this technique cleared from the traditional methods of image inpainting that it is not only reconstruct the image with new content but also specifies and compress structures available in surrounding region whereas other techniques only focuses and borrow textures from the remaining image. This model is trained with two dataset where fully feedforward partial convolution network is experimented. This gives better qualitative image reconstruction because it comprises both the contextual attention and partial convolution method.

This essay plies potential connections among Two-Spirit and Palestinian queer critiques to advance a comparative analysis of queer settler colonialism in Canada and Israel. Abroad literature in indigenous studies and at its intersections with queer studies now centres the intellectual and political interventions of Indigenous LGBTQ/Two-Spirit people in North America. In turn, after years of organising among Palestinian LGBTQ people in Palestine, Israel, and the diaspora, a broad array of queer critiques of gender and sexuality in Israel/Palestine recently has appeared in social movements and scholarship. This essay compares Two-Spirit and Palestinian queer critiques so as to newly examine the sexualisation of settler colonialism in Canada and Israel. The essay cites an extensive literature on queer settler colonialism in the Americas, and its comparability with queer Palestinian critiques, to illuminate the specificity of queer settler colonialism in Israel. An extended analysis of Eytan Fox's 2006 film The Bubble assists in diagnosing the complicities and investments in settler colonialism that characterise contemporary Israeli LGBTQ politics. The essay concludes by demonstrating how such comparisons deepen knowledge of the relational formation of settler colonialisms, and of their inherently gendered and sexualised formation.


We say that an element $x$ of a topological space $X$ avoids measures if for every Borel measure $\mu$ on $X$ if $\mu(\{x\})=0$, then there is an open $U\ni x$ such that $\mu(U)=0$. The negation of this property can viewed as a local version of the property of supporting a strictly positive measure. We study points avoiding measures in the general setting as well as in the context of $\omega^\ast$, the remainder of Stone-\v{C}ech compactification of $\omega$.

One of the drawbacks of an orthogonal frequency division multiplexing (OFDM) system is the larger peak to averaged power ratio (PAPR). The PAPR reduction scheme is a complicated problem, especially when a resource allocation is considered jointly. In this paper, a joint algorithm for determining an optimal resource allocation with PAPR awareness is proposed. Firstly, an adaptive tone reservation assignment is performed by optimally choosing a group of subcarriers, whose channel gains are sufficiently high, to be the data subcarriers and the remaining subcarriers will be used as the reserved tones for reducing PAPR to the desired level. Secondly, an adaptive power adjustment for PAPR reduction technique is introduced for determining the allocated power of data subcarriers by using the water-filling approach with the joint PAPR and capacity constraints. By using the proposed joint algorithm, the PAPR threshold level is satisfied while the desired capacity could be achieved. From the results, the proposed algorithm achieves the better results comparing with a conventional partial transmit sequence (PTS) technique and the tone reservation (TR) technique in terms of PAPR, and probability of error performances, in which the side information is not required, in contrast with the other techniques.


This paper concentrates on the bidirectional control for LLC resonant converter in high voltage application. Due to the different voltage gain curve, the smooth transition between forward mode and backward mode for LLC resonant converter could hardly be obtained. A novel control strategy is proposed to realize the smooth transition at fixed high operating frequency, and the high operating frequency is benefit for the lightweight design of transformer. Furthermore, the control strategy could also reduce the turn-off loss and improve the reliability of the IGBT devices at low voltage side. Finally, experimental results are provided to verify the effectiveness and validity of the proposed control strategy.


Reinforced concrete (RC) short columns subjected to combined axial compression and biaxial bending are frequently encountered in RC structures such as buildings and bridges. Generally, the determination of the ultimate strength for RC columns of generic cross sections under eccentric compressive loading is rather tedious and time consuming. With the rapid development of personal microcomputers and supporting software, it is now possible to develop analysis capabilities in the user-friendly environment of spreadsheets. The program BICOL has been developed for this purpose using Excel 3.1 for Windows. It is user-friendly in that interactive graphic buttons and frequent help messages are displayed at each stage of the program to enable the user to define and analyze a desired section or reanalyze an existing section for different input parameters.


The invention provides a filter net of a generator of an automobile supplemental restraint system. According to the filer net, a gas agent expansion space is reserved in the middle of a whole tubular net body formed integrally by winding a metal wire. Through the tubular net body formed through winding, when the filter net is in use and after an ignition device ignites gas agents in the expansion space, the gas agents which expand instantaneously can be filtered out and discharged out quickly through the tubular net body to expand the supplemental restraint system. The filter net of the generator of the automobile supplemental restraint system is good in effect, safe and reliable.


His researches included the identification of four new sugars in honey, and the establishment of gluconic acid as the principal acid in honey – produced by the action of the enzyme glucose oxidase on the glucose in it. He also established the basis for honey's antibiotic properties: in diluted honey, the glucose oxidase also produces hydrogen peroxide from the glucose present. Other publications described the development and improvement of methods of identifying adulterants in honey. In Honey, an 88-page publication in Advances in Food Research (1978), Dr White covered all scientific aspects of honey, and provided a valuable summary of his researches in the USDA. After his retirement he moved to Navasota in Texas, where he continued his work and published further papers. He also contributed chapters to a number of books, including chapters 5 and 6 in Honey: a comprehensive survey edited by Eva Crane in 1975, and chapter 21 in J M Graham's 1992 revision of The hive and the honey bee.

In order to realize the safe and efficient movement of the robot, the method of constructing the grid map with local uncertainty of a mobile robot based on Kinect sensor is proposed. The robot's working environment is divided into three parts: the free area, the obstacle area and the unknown area. Kinect sensor is used to detect each area and determine the confidence level of the obstacles. Finally, the local grid map of the robot environment is constructed. Taking the wheeled mobile robot as the experimental platform, the possibility of the proposed algorithm is verified.


We apply the theory of partially observable Markov decision processes (POMDPs) to the design of guidance algorithms for controlling the motion of unmanned aerial vehicles (UAVs) with on-board sensors for tracking multiple ground targets. While POMDPs are intractable to optimize exactly, principled approximation methods can be devised based on Bellman's principle.We introduce a new approximation method called nominal belief-state optimization (NBO). We show that NBO, combined with other application-specific approximations and techniques within the POMDP framework, produces a practical design that coordinates the UAVs to achieve good long-term mean-squared-error tracking performance in the presence of occlusions and dynamic constraints.

Abstract Resilience is defined as a personal quality that enables growth in knowledge, understanding and self-actualization in the face of adversity and life disruptions. Low levels of resilience can dispose older adults to higher risks for negative health outcomes in the aftermath of traumatic events. However, we have limited knowledge of resilience among minority aging populations. This study aims to examine the presence and levels of resilience and its sociodemographic correlates among U.S. Chinese older adults. Data were drawn from the Population Study of Chinese Elderly, an epidemiology study of U.S. Chinese older adults in the Greater Chicago area. Guided by a community-based participatory research approach, a total of 3,036 Chinese older adults aged 60 and above participated in face-to-face interviews from 2015 to 2017. Spearman's rank-order coefficient was utilized to test correlation. A 10-item validated Chinese version of the Connor-Davidson resilience scale was used to assess resilience. In our sample, 59.7% were female, and the average age was 75. The mean resilience score was 26.9, ranging from 1 to 40. U.S. Chinese older adults who were younger, male, married, had higher education and income, fewer children, better health status and quality of life, and improved health and have lived fewer years in the U.S. reported higher levels of resilience. Future longitudinal research is needed to investigate the protective effects of resilience among older Chinese Americans against mental and physical distress.

This study was designed to investigate how viewing a variety of pair-planting affects the psychological and physiological reactions of Canadian individuals. For this purpose, eye movement and impression evaluations results of 25 Canadian individuals were collected. The evidences from this study confirmed that Canadian subjects liked the pair planting pattern of globular tree of same form best, and their eye fixation distributed on relatively restricted area in each object tree but not the space between two trees. So, we considered the convergence of eye fixation in each tree of pair planting indicate the favorite degree of pair planting pattern in case of Canadian individuals. Moreover, Canadian individuals prefer globular paired trees combination rather than other patterns. Meanwhile, Canadian subjects disliked the pair planting pattern of fastigiated tree in different form most. Furthermore, eye fixation number and eye fixation duration were equally distributed to the two trees of those patterns who got like or normal evaluation. Contrarily, eye fixation number or eye fixation duration were unequally distributed to the two trees of those patterns who got dislike evaluation. Therefore, we could point out a relationship among favorite degree of pair planting pattern, eye movement, and general planting pattern in Canada.


Abstract : A procedure based on inviscid flow theory is detailed for the design of propeller ducts to reduce specific spatial non-uniform in given nominal ship wakes. The objective is to produce net flows to enclosed propellers which will reduce cavitation and vibratory forces. The process yields peripheral variations of camber and conicity angle which will reduce the amplitude of specific wake harmonics to a maximum extent possible under the arbitrarily imposed constraint that the maximum sectional normal force coefficient must not exceed unity. Applications are made to reduce the first shaft of two wakes showing resultant first harmonics reduced by factors of 4 and 1.40 in the 0.8 radius region.

The thiomorpholin-3-one ring adopts a screw-boat conformation and the attached benzene ring makes a dihedral angle of 42.26 (7)° with the mean plane through the 3-phenyl-4,5-dihydroisoxazol-5-yl ring system. In the crystal, molecules are linked by pairs of C—H⋯N hydrogen bonds, forming inversion dimers. These dimers are linked via C—H⋯O hydrogen bonds, generating a three-dimensional network.


The work is devoted to the problem of scattering of monochromatic electromagnetic waves on heterogeneous dielectric inclusions of arbitrary shapes. For the numerical solution of the problem, the volume integral equation for the electric fleld in the region occupied by the inclusion is used. Discretization of this equation is carried out by Gaussian approximating functions. For such functions, the elements of the matrix of the discretized problem are calculated in explicit analytical forms. For a regular grid of approximating nodes, the matrix of the discretized problem proves to have the Toeplitz structure, and the matrix-vector product with such matrices can be carried out by the Fast Fourier Transform technique. The latter strongly accelerates the process of the iterative solution of the discretized problem. Electric flelds inside a spherical inclusion and its difierential cross-sections are calculated and compared with the exact (Mie) solution for various wave lengths of the incident fleld. Internal electric flelds and the difierential cross-sections of a cylindrical inclusion are calculated for the incident flelds of various directions and wave lengths.

: We report here experimental results investigating the influence of the initial swift heavy ion charge on the structure of polyethylene terephthalate (PET) film after irradiation, using a structurally sensitive X-ray di ff raction method. Kr ions with an energy of 100 MeV and charges of 13 + , 14 + , and 15 + were each used at irradiation fluences of 5 × 10 10 , 7.5 × 10 10 , 1 × 10 11 , 2.5 × 10 11 and 5 × 10 11 ions / cm 2 . At constant energy and irradiation fluence, the post-irradiation structural changes in PET film show a clear dependence on the initial ion charge. As either the fluence or ion charge increase, the latent tracks begin to overlap, leading to cross-linking of PET chain molecules to form rotational isomers (rotamers). We use the fluence corresponding to the onset of overlapping to estimate the size of latent tracks for di ff erent ion charges. At the highest fluences, the latent tracks become entirely overlapped, and the interchain cross-linking extends throughout the whole film. Since this cross-linking is due to the dipole–dipole interaction of subunits of repeat units of PET chain molecules, it is reversible, in contrast to the well-known chemical cross-linking of polymer chain molecules under irradiation.

In the analysis of spatial point patterns on linear networks, a critical statistical objective is estimating the first-order intensity function, representing the expected number of points within specific subsets of the network. Typically, non-parametric approaches employing heating kernels are used for this estimation. However, a significant challenge arises in selecting appropriate bandwidths before conducting the estimation. We study an intensity estimation mechanism that overcomes this limitation using adaptive estimators, where bandwidths adapt to the data points in the pattern. While adaptive estimators have been explored in other contexts, their application in linear networks remains underexplored. We investigate the adaptive intensity estimator within the linear network context and extend a partitioning technique based on bandwidth quantiles to expedite the estimation process significantly. Through simulations, we demonstrate the efficacy of this technique, showing that the partition estimator closely approximates the direct estimator while drastically reducing computation time. As a practical application, we employ our method to estimate the intensity of traffic accidents in a neighbourhood in Medellin, Colombia, showcasing its real-world relevance and efficiency.


In this work a study of nanoindentation of the surface of epoxypolyester-based powder coatings deposited on steel substrates was carried out. The effect of the test method on the identifiable mechanical properties is investigated. The measurement results obtained by using a spherical indenter and a Berkovich indenter are compared. Estimates of reduced modulus of elasticity, Young's modulus and rigidity of coatings are obtained. The experimental data obtained indicate a significant dependence of the determined mechanical properties of the paint and varnish coatings depending on the type of indenter used. In the case of Berkovich indenter, the Young's modulus of coatings (0.6 GPa) is understated in relation to coating properties known from macro experiments (3 GPa). Using a spherical indenter, Young's modulus is overestimated (6.3 GPa).


The performance of a soft x‐ray undulator beamline equipped with a 10 m grazing incidence monochromator is described. Several experimental results are presented to exemplify the good performance. The decomposition of photoabsorption spectra of CO and O2 into their component molecular symmetries has been achieved by our new experimental technique of angle‐resolved photoion spectroscopy. Two Rydberg series converging to the K‐shell ionization limits of O2 have been revealed in a high resolution spectrum.


The student of the art of the Middle Ages finds himself confronted again and again with the question, "What were the ultimate sources from which the mediaeval artists drew their inspiration?" In most cases a literary source can be found, for mediaeval art is primarily one of illustration, and the research of recent years has accomplished much to answer the question by tracing the descent of iconographic types and compositions from the home of their creation. But style is a more elusive element that tends to lose its original quality and appearance with repeated copying when freedom of rendering is permissible and each successive artist may superimpose his individual style upon that of his model. Nevertheless, it has recently been shown that a number of East Christian manuscripts of varying dates exhibit certain qualities of style and composition which can be traced to Alexandria in the early centuries of the Christian era.1 In Rome in the seventh century a short-lived revival of Alexandrian style left its...

We propose a local measure of the relationship between parameter estimates and the moments of the data they depend on. Our measure can be computed at negligible cost even for complex structural models. We argue that reporting this measure can increase the transparency of structural estimates, making it easier for readers to predict the way violations of identifying assumptions would affect the results. When the key assumptions are orthogonality between error terms and excluded instruments, we show that our measure provides a natural extension of the omitted variables bias formula for nonlinear models. We illustrate with applications to published articles in several fields of economics.


Purpose – The extant international service marketing literature focuses heavily on the impact of globalization on the outward process of the internationalization of service firms. The purpose of this paper is to propose scholars examine international service marketing from a different perspective, that of the globalization of domestic markets and the existence of global segments throughout the world.Design/methodology/approach – The paper uses resource‐advantage theory and a congruence approach to suggest that the alignment of resources with consumer needs in the globalized domestic market leads to competitive advantage for the firm.Findings – It can be argued that this alignment will lead to the replication of the competitive advantage across global segments in expansion to new markets.Originality/value – The paper provides two significant contributions to the literature: a new perspective for considering the globalization of services that incorporates the challenges of operating in globalized markets; a...


We improve previous end-to-end differentiable neural networks (NNs) with fast weight memories. A gate mechanism updates fast weights at every time step of a sequence through two separate outer-product-based matrices generated by slow parts of the architecture. The system is trained on a complex sequence to sequence variation of the Associative Retrieval Problem with roughly 50 times more temporal memory (i.e. time-varying variables) than similar-sized standard recurrent NNs (RNNs). In terms of accuracy and number of parameters, our architecture outperforms a variety of RNNs, including Long Short-Term Memory, Hypernetworks, and related fast weight architectures. We relate this to meta-learning through an experiment which shows how the slow weights can learn an on-line learning program which can generate a smaller program able to answer a set of queries.


Increasing degrees of automation of production systems lead to a reduced numbers of operators and parallel to an increase of the number of process information each operator has to supervise and control. This article presents a concept for the design of graphical user interfaces in the area of industrial automation. The concept uses techniques known from the three-dimensional computer graphics and information structure based on the operators task to present the production systems adapted to the human information processing. Experiments verified the capacity of this concept.


In recent decades, pathological consumption has become a growing behavioral misbehavior. Impulsive consumption is governed by two internal behavioral mechanisms that respond fundamentally to the hedonism or Pascal effect and to the emulation or Veblen effect. Today's development of technology acts as a catalyst of consumption by increasing access and availability to products, as well as the advertisement impact. This paper presents a compartmental discrete matrix mathematical model that allows short‐term estimates of ordinary, impulsive, and pathological buyers in Spain in three different economic scenarios. The results show that impulsive and pathological buyers will increase in all the economic scenarios. Notable differences in the number of ordinary buyers are found for the group aged over 65 years.

Abstract Classification algorithms face difficulties when one or more classes have limited training data. We are particularly interested in classification trees, due to their interpretability and flexibility. When data are limited in one or more of the classes, the estimated decision boundaries are often irregularly shaped due to the limited sample size, leading to poor generalization error. We propose a novel approach that penalizes the Surface-to-Volume Ratio (SVR) of the decision set, obtaining a new class of SVR-Tree algorithms. We develop a simple and computationally efficient implementation while proving estimation consistency for SVR-Tree and rate of convergence for an idealized empirical risk minimizer of SVR-Tree. SVR-Tree is compared with multiple algorithms that are designed to deal with imbalance through real data applications. Supplementary materials for this article are available online.

Introduction: Mitral valve prolapse (MVP) is the most common anomaly of mitral valve with different incidence (using modern criteria) and different level of pathoanatomical abnormality. In most of the cases MVP is an isolated anomaly, but can be associated with other heart anomalies, most frequently with interatrial communication. Using the echocardiography several sequelae and complications of MVP can be identified, including mitral regurgitation, ruptured chordae, endocarditis or associations anomalies. Aim of presentation: Using the echocardiography examination to present mitral valve prolapse associated with different forms of interatrial communication. Methodology: Cross-sectional, Doppler and color-Doppler echocardiography examination. Results: During the period 2004 - 2009. in Echo-labor of Pediatrics Clinic in Prishtina were registered 214 children with MVP. 36 of them had one type of interatrial communications. Most often was persistent foramen ovale (22 children), hemodinamicly irrelevant. In 9 of them was registered restrictive ASD secundum type. 5 children had nonrestrictive ASD, one of them type VCS. In all children with nonrestrictive ASD closure was preformed, while in 2 of them open heart surgery was done.


The synthesis of dimethoxydiphenylmethane (DMODPM) from the reaction of methanol and dichlorodiphenylmethane (DCDPM) was successfully carried out in a liquid−liquid phase-transfer catalytic (LLPTC) reaction assisted by ultrasonic irradiation. Little of the desired product DMODPM was obtained from the reaction in the presence of only potassium hydroxide and quaternary ammonium salts. The production of the DMODPM product was greatly enhanced when the reaction system was irradiated by ultrasonic waves. Two sequential reactions in the organic-phase solution proceed to produce the desired product. However, the second rate of the organic-phase reaction was faster than the first. Therefore, the first intermediate product, chloromethoxydiphenylmethane (CMODPM), was not detected during or after the reaction. A kinetic model was developed based on the experimental data. A pseudo-steady-state hypothesis (PSSH) was employed to describe the characteristic behaviors of the kinetic data. The results were finally describ...


Cyclodextrins are among the most popular host compounds in supramolecular chemistry. In this paper we describe a versatile approach to the multivalent functionalization of cyclodextrins by using photochemical thiol-alkene addition reactions ("thiol-ene click chemistry"). Starting from cyclodextrins allylated at the 2-OH, 3-OH and/or 6-OH positions, a range of thiols could be introduced in good to excellent yields. By using alkanethiols substituted with hydroxy, carboxylic acid, ester, protected amine, and tetraethyleneglycol groups, a broad variety of functionalized cyclodextrins was obtained. By using fluorinated alkanethiols, highly fluorinated cyclodextrins (up to 56 wt.-% of fluorine) were obtained in excellent yield.

Pandey Genetic enhancement for higher yield potential through the exploitation of diverse gene pool from the groups of cultivated rice, Oryza sativa L., indica and japonica can be achieved through utilization of wide-compatible varieties which possess neutral allele S5 n for normal spikelet fertility from intersubspecific hybrids. As a pre-requisite, detailed investigations on several aspects of genetics of the trait is required for real exploitation. The present study was therefore, undertaken with objectives to (i) study the nature of inheritance of we trait, (ii) determine its linkage with some marker for selection, (iii) estimation of efficiency of different we genes and (iv) analysis of allelic relationship among we gene(s), using 13 wev's that included eight elite indica, three aus and two tropical japonicas with three testers, as the basic material. Study of F J and three-variety paired test crosses of indica wev's RP 1579-1701-1318, RP \967-20503-1241, UPR 1279-1-4-1, Pusa 560-2-203-338, Narendra 118, UPRI 95-169, UPRI 95-170 and UPRI 95-174 revealed the wide-compatibility trait to be controlled by single gene with dominance of wide-compatibility over narrow compatibility. The we gene in seven of the wev's revealed loose linkage with chromogen ,gene(e+) for anthocyanin pigmentation in apiculus colour on chromosome 6, with mean recombination value of 33.72%. In respect of Narendra 118, no such linkage was revealed as the gene was independent of chromogen gene. High fertility levels in Fl hybrids of wev's with indica andjaponica testers indicated high efficiency of we gene(s) more particularly the genes ofWeV's RP 1579-l701-1318, N 22, Dular and Moroberkan. Other promising and efficient wev genotypes were UPRI 95-170, RP 1967-20503-1241, UPRI 95-174 and Palawan. Elite indica wev's had additional advantage over aus and tropical japonicas with respect to improved plant type, early to medium duration, grain type and good yielding ability with potential of giving superior hybrids and segregants in later generations. The crosses of . wevs with indica and japonica testers revealed the genetic mechanism of hybrid fertility in Fl and F2 generations to be different. Spikelet fertility data on Fh F2 and three variety cross progenies of all the wev indicas revealed the genes to be non-allelic to N22, Dular, Lambaye Que (aus), Moroberkan and Palawan (Tropical japonica). However, the we locus in Narendra 118 was allelic to fertility locus in Lambaye Que and similarly, UPRI 95-169 and UPRI 95-170 genes were having the same gene as the wev Palawan. All the indica wevs showed non-allelic relationship of we genes among themselves. Different modified trigenic and digenic ratios in respective segregating generations also confirmed the non-allelic nature of we gene(s).

Neutron inelastic scattering experiments have been carried out to measure the energies and widths of the crystalline electric-field transitions in the light (rare-earth)-Pd3 compounds. The crystal-field parameters have been determined for PrPd3 and NdPd3, while no crystal-field transitions have been observed in CePd3. The energies and widths of the observed crystal-field transitions are almost independent of temperature. The results are correlated in terms of reduced crystal-field parameters which provide an extrapolation scheme for all (rare-earth)-Pd3 compounds.

Additionally, sensing physical information based on the wireless sensor device helps more intelligent services to incorporate the ubiquitous paradigm into the home networks. In this paper, we address the new smart device with the various sensing ability as well as the wireless communication in order to implement the real ubiquitous house. Moreover, we suggest the new intelligent home scenarios based on the new devices and embedded systems. To show the realistic of our works, we develop a small model house by using our smart devices, RFID and embedded devices. Our works can be contributed the developing of the ubiquitous computing and the real implementations for home networks.


The Canterbury Puzzles is a delightful collection of posers based on the exploits of the same group of pilgrims introduced by Geoffrey Chaucer in The Canterbury Tales. The anthology was compiled by the English puzzlist Henry Ernest Dudeney and first published in 1907. All the puzzles are mathematical in nature and many of them may be used to illustrate O.R. techniques. The following riddle, taken from the chapter entitled 'The Merry Monks of Riddlewell' is a classical I.P. allocation problem.

The emission spectra and the excitation spectra of various emissions have been measured in LiF crystals at 9 K using VUV radiation of 10–33 eV. In contrast to the luminescence of self-trapped excitons (3.4 eV), the efficiency of several extrinsic emissions (4.2, 4.6 and 5.8 eV) is very low in the region of an exciton absorption (12.4–14.2 eV). A single exciting photon of 28–33 eV is able to create a primary electron–hole (e–h) pair and a secondary exciton. The tunnel phosphorescence has been detected after the irradiation of LiF by an electron beam or x-rays at 6 K, and several peaks of thermally stimulated luminescence (TSL) at 12–170 K appeared at the heating of the sample. It was confirmed that the TSL at 130–150 K is related to the diffusion of self-trapped holes (VK centres). The TSL peak at ∼160 K is ascribed to the thermal ionization of F′ centres. The TSL at 20–30 K and 50–65 K is caused by the diffusion of interstitial fluorine ions (I centres) or H interstitials, respectively. The TSL peak at ∼13 K, the most intense after electron or x-irradiation, cannot be detected after LiF irradiation by VUV radiation, selectively forming excitons or e–h pairs. The creation of a spatially correlated anion exciton and an e–h pair is needed for the appearance of this peak: an exciton decays into an F–H pair, a hole forms a VK and an electron transforms H into I (an F–I–VK group is formed) or an F centre into a two-electron F′ centre (an F′-H -VK group). The analysis of the elementary components of the 9–16 K TSL showed that a phonon-induced radiative tunnel recombination of F′–VK (5.6 eV), F–H (∼3 eV) and F–VK (3.4 eV) occurs within these groups.


Abstract:  We considered the possible effects Passenger Pigeon (Ectopistes migratorius) flocks may have had on the disturbance regime and species composition of presettlement forests in eastern North America. We suggest that the activities of roosting and nesting Passenger Pigeons caused widespread, frequent disturbances in presettlement eastern forests through tree limb and stem breakage and nutrient deposition from pigeon excrement. We suspect that the deposition of fine fuels resulting from such disturbances may have influenced fire intensity and frequency in presettlement forests. Further, we propose that consumption of vast quantities of acorns by pigeons during the spring breeding season may partially explain the dominance of white oak (Quercus alba) throughout much of the presettlement north‐central hardwoods region. Consequently, the pigeon's extinction may have facilitated the increase and expansion of northern red oak (Quercus rubra) during the twentieth century. Although it is difficult to accurately quantify how physical and chemical disturbances and mast consumption by Passenger Pigeon flocks affected forest ecology, we suspect they shaped landscape structure and species composition in eastern forests prior to the twentieth century. We believe their impact should be accounted for in estimates of the range of natural variability of conditions in eastern hardwood forests.


In this paper, we transform a class of differential delay equations to Hamiltonian systems. By a direct computatation of Maslov-type index, we establish the existence of periodic orbits of the equations.


This paper examines the employment status and occupational destination of recent vocational education and training (VET) students and how this relates to the training they have undertaken. In particular, it focuses on what kind of match there is between what the person is training for, and how that training is subsequently used. Sociological literature on job searching and employer hiring shows that there is no simple functional relationship between formal skill acquisition in a program of training and skill utilisation in the workplace. That does not prevent, however, training program administrators in Australia from operating as if this functional relationship applied. The allocation of public funds for VET each year is determined between individual state training authorities and the Australian National Training Authority on the basis of plans which associate the training activity with what might be termed the "intended occupation". In the next section we briefly review some of the literature on job searching and employer hiring, and provide more detail on how the intended occupation of training activity is used in resource allocation planning. This is then followed by a section which uses the 2003 TAFE Student Outcomes Survey to examine the association between the attributes of the training and employment outcomes. That analysis is extended in the following section to look more specifically at the match between the intended and destination occupation. The final section concludes with a discussion about what the findings mean for resource allocation planning in VET and some suggestions on how this issue might be more thoroughly investigated.


Cancer diseases are a problem with worldwide importance. However, the the lack of selectivity and induction of toxic side effect during conventional cancer therapy continue to provoke the search of innovative treatment approaches. Recent scientific results have reported for synergistic effect between combination of natural products and chemotherapeutic drugs. In this aspect, flavonoids, which are widely distributed in nature, are well known to exhibit numerous biological activities, including antioxidant, antibacterial, anti-inflammatory, anti-viral and anti-cancer effects and may also, play a role in cancer prevention. In the present study, the effects of low concentrations of catechin hydrate and epigallocatechin, Acacia Catechu spay-dried extract, on cell viability of leukemia lymphocytes were investigated and compared, in order to provide an experimental basis for their future incorporation into newly-synthesized biopolymer particles.


Due to the observation of undergraduate engineering students, we have seen some problems in their information communication. This is not an issue of language, but the point is a lack of descriptive story. The audience (information receiver) cannot build the objects or somethings corresponding to the sender's verbal and sometimes it leads to misleading. In this paper, game-based learning using LEGO block building is applied to improve the descriptively verbal skill. The special model, such as a half bird-half dinosaur creature or something that is not a general object, is used as the prototype model. All members of each team cannot see this model except the team leader which will describe the model information to two sub-leaders one by one. The model information will be divided into two parts for each sub-leader which will carry this information to the members of each subgroup. Finally, the finished 3D figure from all teams will be compared with the prototype model. Results show that most of them quite similar to the prototype. However, allowing the opportunity to talk with the team leader again can increase the similarity of the model. This activity can be done in 2-3 hours with 5-10 persons per team.


Link adaptation is one of the key technologies used in high speed wireless networks such as HSDPA and mobile WiMAX. The dynamic feature of mobile users' channel capacities brings challenges to the call admission control algorithm deployed for such networks. Our aim in this paper is to develop an admission control scheme that handles the intra-cell mobility issue in the downlink of broadband wireless networks with link adaptation. When the cell is decomposed into "rings", the intra-cell mobility can be modeled as a BCMP queuing chain network. Additionally, a change detection system is employed to track the non-stationary parameters. Our cell mobility-based admission control algorithm can provide efficient resource allocation by predicting min-guaranteed resource consumption on a per cell basis.


Over time, the accuracy and speed by which a material can be characterized should improve. Today, the Nicolson–Ross–Weir (NRW) methodology represents a well-established method for extracting complex dielectric properties at microwave frequencies, with the use of a modern vector network analyzer. However, as will be seen, this approach suffers from three fundamental limitations to accuracy. Challenging NRW methods requires a methodical and robust investigation. To this end, using a dielectric-filled metal-pipe rectangular waveguide, five independent approaches are employed to accurately characterize the sample at the Fabry–Pérot resonance frequency (non-frequency dispersive modeling). In addition, manual Graphical and automated Renormalization spectroscopic approaches are introduced for the first time in the waveguide. The results from these various modeling strategies are then compared and contrasted to NRW approaches. As a timely exemplar, 3-D printed acrylonitrile–butadiene–styrene (ABS) samples are characterized and the results are compared with existing data available in the open literature. It is found that the various Fabry–Pérot resonance model results all agree with one another and validate the two new spectroscopic approaches; in doing so, exposing three limitations of the NRW methods. It is also shown that extracted dielectric properties for ABS differ from previously reported results and reasons for this are discussed. From measurement noise resilience analysis, a methodology is presented for determining the upper bound signal-to-noise ratio for the vector network analyzer (not normally associated with such instrumentation). Finally, fused deposition modeling (FDM) 3-D printing can result in a non-homogeneous sample that excites open-box mode resonances. This phenomenon is investigated for the first time analytically and with various modeling strategies.


Three-dimensional wave patterns on a film flowing down a uniformly heated wall are investigated. Combining a gradient expansion with a Galerkin method, a model of four evolution equations for the film thickness, the surface temperature and both the streamwise and spanwise flow rates is shown to be robust and accurate in describing the competition between hydrodynamic waves and thermocapillary effects in a large range parameters. For small Reynolds number, {\it i.e.} in the drag-gravity regime, regularly spaced rivulets are observed, aligned with the flow and fostering quasi-two-dimensional waves of larger amplitude and phase speed than those observed in isothermal conditions. For larger Reynolds number, {\it i.e.} in the drag-inertia regime, the picture is similar to the isothermal case and no rivulets are observed. The transition between these two situations shows complex cooperative behaviors between both hydrodynamic and thermocapillary modes. Additionally, this transition is found to be related to the variations of amplitude and speed of the spanwise independent solitary wave solutions to the model.


Piezoelectric stack actuators, which have been widely used in precise positioning applications, suffer from the well-known hysteresis effect. Although numerous approaches such as sensor-based control and feedforward control have been proved to be effective, the resulting high cost and system complexity limit their use in industry. In this paper, the design and validation of a nonlinear charge controller (NCC) is presented for achieving highly linear operation of the actuator in a sensorless way, without modeling hysteretic nonlinearity. In the proposed scheme, the output voltage of traditional linear charge controller (LCC), which contains information of hysteresis, has been processed and utilized as feedback signals. As a result, controller outputs with tunable nonlinearity have been achieved, aiming to improve the observed overcompensation effect. Experimental results show that the dynamic tracking performance of the NCC is superior to LCC approach. The positioning error has been reduced to 0.4% of the travel range, corresponding to a nonlinearity reduction of 97%.


Previous research has demonstrated that sub‐threshold amyloid‐beta retention is related to cognitive performance, functional brain change, and further amyloid‐beta /tau accumulation. However, few previous studies have examined an effect of APOE genotype on the association between functional connectivity (FC) and memory performance in the earliest stage of Alzheimer's disease (AD). We aimed to evaluate the difference in intra‐ and inter‐regional FC between cognitive older adults with and without APOE ε4‐allele and examined an impact of intra‐ and inter‐regional FC on memory performance in cognitively intact older adults, according to APOE ε4‐allele status.


We show that under the Korteweg–de Vries flow an initial profile supported on (−∞, 0) from a very broad function class (without any decay assumption) instantaneously evolves into a meromorphic function with no poles on the real line. Our treatment is based on a suitable modification of the inverse scattering transform and a detailed investigation of the Titchmarsh–Weyl m-function. As a by-product, we improve some related results of others.


Recognition system based on skin color is main method of character detection of face and hand. This paper analyzed some common method of transformation of image enhance on the basis of YCbCr skin color model. A enhance method which is integrated exponential and logarithm transformation is proposed. And according to the shortcoming of fixed threshold, an automatic threshold algorithm with the fisher estimate function is proposed. The experiment with this method proves that it can enhance the contrast of foreground and background, and has good robust. The algorithm in paper is more adaptive in the recognition and detection than the fixed threshold method.


The method for purifying an alkanesulfonyl chloride (CAS) to reduce the sulphate content is to wash the alkanesulfonyl chloride with water or with an aqueous solution of an acid having a pH between 0.57 and 7, and then separating the alkanesulfonyl chloride and purified from the aqueous phase. This CAS purified conduit by total hydrolysis of the alkanesulfonic acid to sulfuric acid content low.


This paper proposes an improved Trie tree structure. The tree node records the position information of the characters participating in the word formation, and the child node uses the hash search mechanism. On this basis, the forward maximum matching algorithm of Chinese word segmentation is optimized. In the process of word segmentation, the automaton mechanism is used to judge whether it constitutes the longest word, and the problem that the forward maximum matching algorithm needs to adjust the string according to the word length is solved. The algorithm time complexity is 1.33, and the comparison test results show that there is a fast word segmentation speed. The forward maximum matching algorithm based on the improved Trie tree structure improves the Chinese word segmentation speed, especially when the dictionary structure needs to be updated in real time.


Meniscal tears are a common cause of stifle lameness in dogs. Use of autologous synoviocytes from the affected stifle is an attractive cell source for tissue engineering replacement fibrocartilage. However, the diseased state of these cells may impede in vitro fibrocartilage formation. Synoviocytes from 12 osteoarthritic ("oaTSB") and 6 normal joints ("nTSB") were cultured as tensioned bioscaffolds and compared for their ability to synthesize fibrocartilage sheets. Gene expression of collagens type I and II were higher and expression of interleukin-6 was lower in oaTSB versus nTSB. Compared with nTSB, oaTSB had more glycosaminoglycan and alpha smooth muscle staining and less collagen I and II staining on histologic analysis, whereas collagen and glycosaminoglycan quantities were similar. In conclusion, osteoarthritic joint—origin synoviocytes can produce extracellular matrix components of meniscal fibrocartilage at similar levels to normal joint—origin synoviocytes, which makes them a potential cell source for canine meniscal tissue engineering.


A partial contact zone model is developed for the stress and electric displacement fields due to the obstruction of a uniform heat flux by an electrically impermeable crack in piezoelectric materials. Green's function method is used to reduce the problem to a set of singular integral equations that are solved in closed form. When the crack is assumed to be traction free, the crack opening displacement is found to be negative over one-half of the crack unless a sufficiently large far field tensile stress is superposed. The problem is reformulated assuming a contact zone at one crack tip. The extent of this zone, the stress and electric displacement intensity factors at each crack tip are obtained as functions of the applied mechanical stress and heat flux.

Business correspondence has been a subject of various advisory literatures and an object of academic writing process research for many years. With the publication of the research report "The Writing Subject", Reinke added a relevant component to the scientific discourse on writing in the business world (Reinke 2019). Superiors who read draft texts are less perceived by the authors as help and much more as control and censorship – this can lead to a change in writing behaviour. In other words: to adapted, uncreative, externally determined letters, whose innovative power – individual originality – can no longer or does not want to develop. Reinke's work follows Kaiser's research (Kaiser, Brötz 2011; Kaiser 2013; Kaiser, Brötz 2015; Kaiser 2017) into the vocational training of office workers as well as Efing's work (Efing 2015; 2017) into professional language registers. By means of a reflective grounded theory, Reinke gains interesting insights into the everyday world of writing merchants – and valuable impulses are created for the relevant training and further education.

SEM users have specific performance goals in mind when they select an instrument. A certain level of resolution is often required to see features of interest as well as to clearly distinguish them from noise or less important adjacent details. Resolution is one of the most difficult terms to understand because it is determined not only by the instrument and operating conditions used but is also sample dependent [1,2]. High resolution has always been linked to the smallest possible probe size that has adequate current needed for a satisfactory signal to noise ratio. The ability to produce small probes has been a major goal of instrument manufacturers and has largely been realized through significant improvements in electron optical systems.


The extraction equilibria of copper(II) with 2-bromoaliphatic carboxylic acids and with conjugated carboxylic acids in benzene were investigated using a curve-fitting method in order to grasp the bonding character of a functional carboxyl group. A monomeric species, CuL_2(HL)_a, together with dimeric copper(II) carboxylate Cu_2L_4(HL)_2 was extracted in the concentration region of copper(II) in the organic phase, C _Cu,o>3×10^–5 mol dm^–3. A new linear relationship between the extraction constant ( K _ex) and the acid dissociation constant ( K _a) was empirically obtained as log K _ex(11)=1.74log K _a–0.75 · (1) for CuL_2·HL and log K _ex(12)=1.37log K _a–1.97 (2) for CuL_2(HL)_2, as well as log K _ex(22)=1.71log K _a–3.17 (3) for the ^=· ^=· dimer. Thus, we can obtain an approximate value of the dimerization constant of copper(II) ( K _dim( a ,2)) in the organic phase from K _a by log K _dim( a ,2)=log K _ex(22)–2log K _ex(1 a ) ( a =1 or 2), except for cases of conjugated carboxylates, which deviate from Eq. (3), due to a lower log K _ex(22). The deviations would be correlated to the change in the dipole moment affected by electronic delocalization with resonance over the conjugated ligand in the bridging form. Therefore, the extraction of a monomer together with a dimer is easily found by using carboxylic acids of low p K _a or of a conjugate.


UDC 517.98 We develop a general theory of PT -symmetric operators. Special attention is given to PT -symmetric quasiself-adjoint extensions of symmetric operator with deficiency indices h2;2i: For these extensions, the possibility of their interpretation as self-adjoint operators in Krein spaces is investigated and the description of nonreal eigenvalues is presented. These abstract results are applied to the Schr¨ odinger operator with Coulomb potential on the real axis.


Hundreds of banks failed during the financial crisis of 2008 to 2010 causing significant social cost and enfeebling economic growth for years following. In the aftermath of the crisis, regulators responded, as always, with new regulations, the efficacy of which is debatable. For policy makers to enact effective regulation, they must understand the true cause of bank failures during crisis periods. We study the effects of 31 variables using univariate t-tests and probit regression to determine their influence on the probability of bank failure. We find that banks failed during the 2008 to 2010 financial crisis because of choices management made to accept more risk, specifically by having higher financial leverage, investing in higher risk loans in real estate and construction and by holding less liquid assets and fewer low risk loans like single family real estate loans. That is, the cause of US bank failures during the finance crisis was poor management.


In most of the developing countries, economic losses arising from the theft of power can difficult the finances and the demand planning of marketers and lead to the collapse of the electrical system of a country. This has led considerable efforts in the search for solutions to detect frauds of energy based on the application of statistical algorithms for the analysis of load patterns. The lack of energy consumption patterns that, in advance, allow to know which users are licit and which are fraudulent is the main difficulty for the determination of the effectiveness in the use of these models. This paper presents the results obtained in the process of design and implementation of a software platform that allows generating consumption patterns corresponding to users within the groups previously mentioned. The MATLAB development environment is used to manage the application and the information about the consumption habits.


Taking Technical Risks-How Innovators, Executives, And Investors Manage High-Tech Risks, by Lewis M. Branscomb and Philip E. Auerswald, 2001, Cambridge, MA: The MIT Press The difficult life of technical innovators and the gaps which have to be covered in order to cross the "death valley" (where the majority of innovative projects fail) give a satisfactory idea of how tough is the way from scientific breakthroughs to market prototypes, or throughout the book-in other words-how difficult it is to control purely technical risks and market risks at the same time. The financial gap between funding of research and resources to be invested to put the projects in practice, the research gap between the initial idea and a market-suitable product, and also the trust gap-or the information asymmetry-between technologists and managers, may seriously affect the underwriting of high-tech risks. Technical breakthroughs no longer coincide with products themselves, as it was once; there is now a difference between an innovating concept and a product ready to be launched. This is the central subject of the book, and also a very typical insurance topic, as everybody can see and realize, although this is not emphasized throughout the work as it could have been. In fact, the risks necessarily related to all innovative projects are normally shared, and risky activities may be undertaken-under insurance mechanisms-which would not have been possible otherwise. At the very heart, the problem originates from the fact that different, sometimes conflicting interests stand on the valley sides. On the one hand "inventors" and technologists are responsible for research and follow the reasons of science, often paying attention to feasibility more than to the impact of proposed innovations. On the other hand investors, and particularly managers, are responsible for decision-making processes and risk firm reputation and money, so that they follow the reasons of market. The volume takes the form of a monograph that is divided in chapters, as usual; among the chapters a series of papers ("contributed essays") can be found, however. These were mostly chosen from the commissioned contributions of a report on "Managing Technical Risks," which was sponsored by the Advanced Technology Program of the NIST (National Institute for Standards and Technology) in the late nineties. Together with the academics, a series of practitioners were involved in the project, and two preliminary workshops were organized to approach the matter. Thus, most of the "added value" comes from the choice to combine continuous, often implicit, reference to theory-from Schumpeter on-with the point of view and the experience of professionals, whose opinions are quoted throughout the book. The Introduction is devoted to elucidate the aims and structure of the book. On the other hand, the first chapter (Between Invention and Innovation)-having introduced the discussion and presented two case studies-offers a useful definition of success and failure in terms of objectives. Institutional, personal, and project objectives are discussed to evaluate technical uncertainties and failure risks. The corresponding contributed essay (Technical Risks, Product Specification, and Market Risk, by George C. Hartman and Mark B. Myers) gives the subject a concrete form, by explaining how research, technology development, and product development activities are structured at the Xerox corporation, according to a model adopted to identify/quantify technology risks and market risks. Risk and uncertainty are analyzed in the following chapter (Defining Risks and Rewards). However, this is not a purely analytical approach, for a "soft way" is chosen to treat the related statistical concepts: the quantification of technical risk is as much an art as it is a science. Some of the methodologies to assess the technical risks are mentioned here: (1) the two-part appraisal, evaluating the global risk as the product between the probability of technical and the probability of commercial successes; and (2) the mapping of the research, development, and commercialization process, in order to simulate a series of scenarios through which a model is to be obtained. …


In this study, the hexane and methanol extracts of Croton campestris A., Ocimum gratissimum L. and Cordia verbenacea DC. were evaluated for antibacterial activity against strains of Escherichia coli and Staphylococcus aureus. The growth of all bacteria tested was inhibited by the extracts. The MIC values ranged from 128 to ≥ 1024 mg / mL. With the results obtained, the hexane and methanol extracts of Croton campestris, Ocimum gratissimum and Cordia verbenacea proved to be a promising source of research in natural products with antibacterial action.


Significance Auxin is a plant hormone required for the establishment of growth orientation. Redistribution of auxin across an organ allows reorientation, and this is achieved through changes in the polar localization of auxin efflux carriers. We have found that when auxin methylation is impaired, auxin is not correctly redistributed on gravistimulation, due to a general increase in basipetal auxin transport and deficient relocalization of auxin transporters. We conclude that auxin must be within a specific concentration range for its correct distribution, and this range is maintained by auxin methylation in the endodermis, the cell type that perceives gravity. Asymmetric auxin distribution is instrumental for the differential growth that causes organ bending on tropic stimuli and curvatures during plant development. Local differences in auxin concentrations are achieved mainly by polarized cellular distribution of PIN auxin transporters, but whether other mechanisms involving auxin homeostasis are also relevant for the formation of auxin gradients is not clear. Here we show that auxin methylation is required for asymmetric auxin distribution across the hypocotyl, particularly during its response to gravity. We found that loss-of-function mutants in Arabidopsis IAA CARBOXYL METHYLTRANSFERASE1 (IAMT1) prematurely unfold the apical hook, and that their hypocotyls are impaired in gravitropic reorientation. This defect is linked to an auxin-dependent increase in PIN gene expression, leading to an increased polar auxin transport and lack of asymmetric distribution of PIN3 in the iamt1 mutant. Gravitropic reorientation in the iamt1 mutant could be restored with either endodermis-specific expression of IAMT1 or partial inhibition of polar auxin transport, which also results in normal PIN gene expression levels. We propose that IAA methylation is necessary in gravity-sensing cells to restrict polar auxin transport within the range of auxin levels that allow for differential responses.

While there is much research to suggest the benefits of placements to the graduate destinations of students in higher education (Lowden et al., 2012; Pegg et al., 2012) there is little literature on the possible differences between students who choose to go on placements compared to those who do not. To this end, a mixed-methods approach was taken to explore these possible differences. Quantitative data included self-reported findings on the Aspiration Scale (O'Brien and Hepner, 1996), Employability skills (Reddy and Moores, 2006), Hope Trait Scale (Snyder et al., 1991) and Self-Perceived Employability Scale (Rothwell et al., 2009). Quantitative data focusing on the differences between placement and non-placement students on said scales were supplemented by qualitative data based on two unstructured focus groups. The qualitative data suggest differences in confidence (placement self-efficacy) and guilt (taking limited placement resources) that might impact on the decision or likelihood of applying for placement. Questions over primary responsibility for securing placements (the individual or the institution) were raised. Implications regarding the heterogeneity of students (especially mature students) were identified suggesting that a 'one size fits all' approach to placements is unlikely to be fruitful.


The Swi/Snf complex is also known as the chromatin-remodeling machine. The Swi/Snf complex plays a key role in the regulation of eukaryotic gene expression. The image below is a representation of the Swi/Snf complex. Each of the ten proteins plays an important part in the complex, due to their strong correlation to several cancer types. We currently are focusing on the INI-1 protein of the complex, which has shown to be correlated to the development of the atypical teratoid/ rhabdoid tumor (AT/RT). AT/RT is a highly malignant central nervous system tumor. Genetic studies have shown that deletion or mutation of the INI1 gene occurs in AT/RT lesions. Our lab is working to understand the biochemistry of the tumor suppressor INI-1 and its role within the Swi/Snf complex. If we are able to determine the function of INI-1 in the Swi/Snf complex, we will be better able to determine treatment for patients with this condition. The goal of my research is to determine which of the ten proteins that are part of the Swi/Snf complex directly interacts with INI-1.


Objective To establish a malignant transformed human fetal osteoblastic human cells from the immortalized cell line hFOB1.19 in order to explore the molecular mechanism in tumorigenesis of osteosarcoma. Methods hFOB1.19 cells were treated sequentially by an initiated factor, N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and a promoter, 12-O-tetradecanoyl phorbol-13-acetate (TPA). The features of malignancy of transformed cells were identified by cell morphology, DNA content analysis, colony forming frequency on soft agar and tumorigenetic test in nude mice. Results Continuous passaging after the treatments resulted in the formation of a few paramorph foci and exhibited in an extensively random orientation. The poly-ploid of DNA was 81.08% in experiment group, much higher than that in control group (55.03%). Compared with that of negative control cell, colony formation efficiency of transformed cells in semisolid agar showed a a significant increase. The transformed cells formed tumors subcutaneously in the nude mice, which were verified to be poorly differentiated osteosarcoma histopathological examination. Conclusion Mocking the process of malignant transformation of human cells, we establish malignant transformed immortalized human fetal osteoblastic human cells (hFOB1.19) model.

The results of an electromechanical transient simulation can be viewed as a time series data set. Storing these data requires a sizeable space, and the considerable data size renders comparative analysis difficult. For mitigating these problems, a method for analysing and describing a discrete-event chain in the dynamic process of a power system is proposed. Based on the symbolic description, the continuous dynamic process is represented as a discrete-event chain, resulting from the change in state variables beyond the given threshold. Therefore, the event-driven electromechanical transient simulation is developed, and the continuous dynamics and discrete-event chain simulation results are obtained. Subsequently, the event relation matrix is obtained, normalised, and then converted into a bitmap. Finally, the k
-means method is used for the cluster analysis on the bitmap of the simulation result. Two test cases involving an IEEE 39-bus system and a practical system are considered. Case studies demonstrate the effectiveness of the proposed method.

This paper develops a status-aware projection metric learning (SPML) method for facial image-based kinship verification, especially for the parent-child kinship. Kinship verification for parent-child is considered to be an asymmetrical metric process, in that parents and children are associated with different status where the parents are priorly known to be significantly older than the children. Accordingly, an SPML is proposed to address the asymmetric metric learning. The proposed SPML takes advantage of two status-specific projections to capture the significant appearance commonality between parents and children, respectively, which generally outperforms the one Mahalanobis distance metric. Extensive experimental results and comparisons with state-of-the-art approaches and baseline methods demonstrate the effectiveness of the proposed SPML for kinship verification.


The purpose of this study was to assess the effects of car pollution on police health in Paris and, more particularly, for policemen working near streets and crossroads. A population of non-exposed policemen was studied as a reference. This work included individual exposure measurements to some urban pollution main indicators and biological determinations to estimate the effects of these pollutants on health. Biological samples of blood, including determinations of carboxyhemoglobin and lead, were taken from 204 male and female police employees. CO and benzene individual exposure were measured on 38 men among these policemen by use of individual analyzers or pump samplings. Three classes of exposure, dependent on police activities, were characterized according to CO and benzene levels of exposure and carboxyhemoglobin concentrations. Results, comparing the levels of pollutants and chemicals in the bloodstream from traffic exposure vs. from smoking are presented and discussed.


Sustainability issues in higher educational institutions' (HEIs) research, especially in the social science field, have attracted increasing levels of attention in higher education administration in recent decades as HEIs are confronted with a growing pressure worldwide to increase the efficiency of their research activities under a limited volume and relatively equitable division of public funding resources. This paper introduces a theoretical analysis framework based on a data envelopment analysis, separating the social science research process into a foundation stage and a construction stage, and then projecting each HEI into certain quadrants to form several clusters according to their overall and stage efficiencies and corresponding Malmquist Productivity Indices. Furthermore, the interfaces are formed in each cluster as feasible potential improvement directions. The empirical results in detail are demonstrated from a data set of Chinese HEIs in Jiangsu Province over the Twelfth Five-Year period as offering a closer approximation to the "China social science research best practice".


Objective To investigate the relationship between CT manifestations and pathologic results in non-ossifying fibroma (NOF). Materials and Methods Spiral CT findings in 13 cases with pathologically proved NOF were retrospectively analyzed, and compared with pathologic results.Results All 13 lesions were located at metaphysis, presenting as eccentric expanded bony destruction with the involvement of bone cortex and a CT value of 58~72 HU. Residual osseous tissue could be seen within the tumor. The lesion protruded into marrow cavity and was isolated from the marrow with a thin bony layer. On MPR, the lesion was oval in shape and extended along the longitudinal axis of the bone. Under direct vision, the tumor was yellow-greyish or brown in color. Microscopically, the tumor was consisted of collagenous fiber bundles and spindle cells arranged in whirlpool shape, and among them multinuclear giant cells and foam cells were disseminated. No osteogenic tissue was found within the tumor.Conclusion Spiral CT scans can precisely reflect the pathologic features of NOF.


Ultra High Molecular Weight PolyEthylene (UHMWPE) is a polymer widely used in hip implants (prostheses) as a bearing surface against metal, because of its good mechanical properties and biocompatibility [1]. Nevertheless, the durability of such implants is limited because of failure resulting from osteolysis and aseptic loosening. These two phenomenons are due to the immune response of human body consecutive to the apparition of wear particles of UHMWPE with time.


This brief proposes the use of passive mixer-first receiver topology to sense signals at higher LO harmonics. The advantages of such a receiver include sensing of multiple bands concurrently and reduced tuning range requirements in the frequency synthesizer. The single and joint harmonic matching performance of a zero-IF  ${M}$ -phase mixer-first receiver is analyzed. It is shown that minimum possible return loss for joint matching occurs when the geometric mean of input impedances at the highest and lowest sensing bands equals the antenna impedance. The noise figure (NF) when sensing higher order LO harmonics is shown to result in only modest degradation, with the loss becoming even less with increasing number of LO phases. As an example, a 12-phase harmonicsensing mixer first receiver is simulated and its performance at first, third, and fifth harmonics is evaluated in terms of input matching and NF.
