by Jeremiah David Edward White Gasless combustion systems offer features that make them attractive tools for a variety of potential applications. Among them are rapid heating rates, high exothermicity, and high maximum temperatures. These characteristics were exploited to accomplish three separate concepts including the joining of refractory materials, synthesis of a porefree composite, and the study of thermal explosion in mechanically activated powders. Honeywell Aerospace is a leading producer of carbon brakes for commercial aircraft. The manufacturing process involves chemical vapor infiltration (CVI) to form a carbon matrix around a carbon fiber preform. A major disadvantage of this approach is the time required to form a fully dense preform, which is on the order of 140 days. In addition, after the brakes are in service, they have to be discarded while there is a relatively thick amount of friction material still available. There is a profit motive for reusing these discs which are out of spec. One such example would be to perform a refurbishment by bonding a new thin C/C element onto a used "core" to produce a brake that meets performance specifications. Unfortunately, joining C/C composites is not a Jeremiah David Edward White simple task, as carbon does not lend itself to welding, and other means (e.g. mechanical or adhesives) would not hold up to the harsh operational conditions. A novel apparatus was designed, built, and proven to join C/C using so-called reactive resistance welding (RRW). It is shown that a joint stronger than the original material can be achieved using moderate electrical current and mechanical force. Additionally, joining layers of similar thickness and microstructure were obtained with different reactive media, ranging from pellets of pressed powders (~ 1-2 mm) to thin metal foils (~ 25 micron). By modifying the schematic of the RRW apparatus, porous C/C was infiltrated with liquid silicon in order to form a new pore-free C/C-SiC composite. It is shown that using such a process, the silicon rapidly fills the open pore structure with only a thin layer of silicon carbide forming around the periphery of the pores. As the high-temperature treatment time is extended, carbon from the composite diffuses through this layer and reacts with the silicon subsequently crystallizing a bulk silicon carbide phase and forming an essentially pore-free composite. The utility of the apparatus was further demonstrated for the study of electrical initiation of an exothermic reactive system, Ni-Al. The effect of short-term high-energy milling on this system was investigated and it was found to significantly decrease the ignition temperature and activation energy without formation of any new phases. Scanning electron microscopy, electron dispersive x-ray spectroscopy, x-ray diffraction, infrared thermal imaging, and mechanical testing were used to study the process dynamics and properties of these materials.


The article describes a new method of planar location and calculation of the velocity of each acoustic emission signal (AE), provides analytical and numerical methods of solution, takes into account the peculiarity of the transition from a spatial problem to a flat one, in which the acoustic emission transducers (AET) that registered the AE signal are located on different sides of the cylinder sweep cut line. It is shown that the developed algorithm for processing AE system data (geometry of the region, coordinates of the AETs, numbers of the AET that registered the signal and the differences in arrival times) makes it possible to eliminate or at least reduce the influence of AE signal location errors associated with setting the speed of sound the same for all AE signals; anisotropy of the AE signal speed; registration by AETs of waves of various types; errors in setting the coordinates of the AETs. The function of noise elimination caused by electromagnetic interference has been added to the algorithm. The article presents the results of numerical experiments for two cylindrical steel thin-walled production facilities: a separator and a desorber column, which demonstrate the adequacy of the proposed mathematical model, as well as the efficiency of the algorithm for calculating the location and speed of AE signals. An assessment of the increase in the accuracy of the location using the LUCY indicator was carried out.


Abstract We demonstrate coherent control in photoemission from a gold needle tip using an ω − 2ω field composed of strong few-cycle laser pulses with a nearfield intensity of ∼4 TW/cm2. We obtain the nearfield intensity from electron energy spectra, showing the tell-tale plateau of field-driven electron rescattering at the metal surface induced by the fundamental field. Changing the relative phase between the fundamental field centered at 1560 nm and its second harmonic modulates the total emitted photocurrent with visibilities of up to 80% despite the strong and broadband excitation of the plasmonic material. Our work combines a two-color coherent control scheme and strong-field physics enabled by a nanoplasmonic emitter.


Large over-parametrized models learned via stochastic gradient descent (SGD) methods have become a key element in modern machine learning. Although SGD methods are very effective in practice, most theoretical analyses of SGD suggest slower convergence than what is empirically observed. In our recent work [8] we analyzed how interpolation, common in modern over-parametrized learning, results in exponential convergence of SGD with constant step size for convex loss functions. In this note, we extend those results to a much broader non-convex function class satisfying the Polyak-Lojasiewicz (PL) condition. A number of important non-convex problems in machine learning, including some classes of neural networks, have been recently shown to satisfy the PL condition. We argue that the PL condition provides a relevant and attractive setting for many machine learning problems, particularly in the over-parametrized regime.


The article discusses the question of what precedes the theoretical formulation of new pedagogical conceptualizations. It is shown that new directions in the development of pedagogical knowledge can appear in accordance with the emerging needs of educational practice. To clarify the question of what structural components of pedagogical theory and in what form are formed at the pre-theoretical stage, as an example, a new conceptualization of "hip-pedagogics" is considered, which solves the problems of rehabilitation and correction. The hypothesis is tested that the direction of Internet search queries in the special Google Trends resource characterizes the features of this stage in the development of theoretical conceptualization, which is reflected in the frequency of the choice of the search query and the features of the lexical form of its representation. It is concluded that the emergence of new conceptualizations is associated, among other things, with the extrapolation of the results obtained on one object of the model to another, which can potentially contain similar characteristics and/or perform similar functions.


End effect of linear induction motor (LIM) brings asymmetry to the inductance matrix, leading to the imbalance of current and thrust ripples. In order to eliminate the current imbalance, inductance measurements and calculations are analyzed in this paper. The voltage strategy is designed through calculations of parameters of three-phase equivalent circuit and current results. The calculated results are validated by the experiments on a prototype of LIM.

Growing interest in marketing history is providing a major new focus for marketing studies. This article examines the benefits of adopting a historical perspective in teaching marketing. This perspective involves both the historical "facts" and the techniques employed by historians, which can be particularly useful in areas unsuited to the application of scientific method. Suggestions are made for incorporating history into the marketing curriculum.

Synopsis

The paper describes the technique for using the microscope in the region 2,000A. to 1,000A. and the instrument for doing this. The experimental work shows that if the instrument is mounted in a chamber containing nitrogen instead of in vacuo the technique is greatly facilitated. Reflecting objectives of the Schwarzschild type and a refracting type monochromat (made in fluorite) have been used in this work. Photomicrographs taken with the instrument are included in the paper.


Data augmentation is a common approach that been implemented in order to increase the training data quantity for Convolutional Neural Networks in signal processing, image recognition and speech recognition. However, the conventional data augmentation methods usually implement the window slicing and overlap window slicing methods in the bearing fault analysis. Meanwhile, the audio deformation approach such as time stretching and pitch shifting methods have been commonly used as data augmentation approach in speech recognition. Thus, this paper proposed a data augmentation based on shift pitching technique for the vibration signal. The relationship between the audio and the vibration signal is evaluated for a bearing fault analysis using Convolution Neural Networks. The new dataset produce by the data augmentation is used to increase the number of training dataset and to improve the Convolutional Neural Networks training performance. The result shows that the shift pitching based data augmentation method able to achieve higher training accuracy compared to the window sliding data augmentation. The combinations of all ratio pitch obtain 93% accuracy whilst the accuracy for a single rate pitch are between 81% to 91%.Thus, the proposed method is competent and able to improve the performance of bearing fault classification


ABSTRACT Dynamics of compensation for the deprivations of segregation and discrimination, and the support of multiculturalism derived from ethnic cohesion explain the consumption of out-of-home highbrow leisure events by minority/ethnic individuals, immigrants, and their descendants as efforts toward their integration and assimilation in metropolitan areas. Using data from the Houston Area Survey, I examine whether there are any significant ethnic disparities in the attendance at museums and live theatres, which represent a relevant dimension of out-of-home highbrow leisure in Houston. I found that the odds of frequently attending museums and live theatres are lower for Anglos compared with non-Anglos, and higher for US-born individuals with at least one foreign parent compared with US-born individuals with US-born parents. These findings reveal that the audiences of museums and live theatres in Houston are already characterized by a noteworthy ethnic diversity.

The red fox is established in the eastern half of Oklahoma. The Mississippi Valley fox, Vulpes vulpes regalis is found in the hilly regions of the State. The eastern fox, V. v. fulva is probably the form found in the Red River Valley. Considerable importation of red foxes into eastern Oklahoma is occurring. The red fox (Vulpes vulpes) is native neither to the Southern Great Plains nor the Gulf Coast. In the Central United States it reaches its western limit in the prairie-grassland ecotone, which in Oklahoma occupies approximately the middle third of the state. This species is seemingly neither as common nor as widespread as the gray fox (Urocyon cinereoargenteus), whose range entirely overlaps that of the red fox in this area. At present, published records give an incomplete picture of the dis- tribution of this species in Oklahoma. Blair (1939) reported that the


This study aims to examine the relationship between approach achievement goals, the fear of shame embarrassment failure, and coping strategies in secondary school science courses. Academic coping was handled in four dimensions: positive, projective, denial, and non-coping. The sample of the study included 249 sixth, seventh, and eighth-grade students studying at one of the largest cities in the eastern part of Turkey. Descriptive statistics of variables were determined with the SPSS program. The relationship between the variables of the study was examined with the path analysis using the Amos program. According to the results of the analysis, a positive correlation was found between performance-approach goals and positive coping strategies. Fear of shame and embarrassment was positively correlated with positive coping and non-coping from the coping strategies and with mastery-approach goals from the approach achievement goals.


We have synthesized Ti–Zr–Ni- and Ti–Hf–Ni-based quasicrystals by the mechanical alloying of elementary powders with an average particle size of 35m in a high-energy planetary ball mill followed by a vacuum heat treatment. The X-ray diffraction (XRD) spectra indicate that the mixture was to a large extent amorphous after mechanically alloying for more than 40 h. These largely amorphous precursors, after various times of mechanical alloying, were subsequently analysed by means of differential scanning calorimetry (DSC) in order to obtain the kinetic parameters of crystallization, such as the temperature and the activation energy. DSC was used in combination with XRD to identify the structural changes related to the peaks in the DSC scans. The morphologies and compositions were analysed using scanning electron microscopy with an energy-dispersive spectrometer. We observed agglomerates ranging in size from 5 to 50m; these agglomerates consisted of smaller particles with sub-micrometer diameters. The composition of the agglomerates was not homogenous, since small areas (∼1m) of Zr-rich secondary phase were observed inside them. Using a vibrating-sample magnetometer (VSM) we found that the saturation magnetization decreases with mechanical treatment, and is additionally decreased with the time and temperature of a subsequent vacuum heat treatment. The saturation magnetization (Ms) decreases fairly linearly, from the initial mixture of crystalline elements, which is ferromagnetic due to nickel, through to a largely amorphous phase, and then to the quasicrystalline phase, where the Ms value is the lowest. As a result, measuring the magnetic properties allows us to probe the structural transformations in the material. © 2007 Elsevier B.V. All rights reserved.


The main advantage of asymmetrical multilevel inverters is the optimization of levels with a minimum number of power supplies. However, this optimized multilevel system still needs a large number of isolated and floating DC supplies, which makes these converters complicated to implement in electric vehicles (EVs), because the system will require many independent battery packs. In this paper, a very simple scheme, based on a small and cheap high frequency link (HFL), allows the utilization of only one power supply for the complete multilevel inverter drive, with an inherent regulation of the voltages supplied among the H-bridges. It also allows voltage control with full number of levels if the DC power supply is of variable voltage characteristic. This work is focused on a 27-level asymmetric inverter but the strategy, using only one power supply, can be applied to converters with any number of levels. In particular, an asymmetrical 27-level converter needs nine isolated power supplies and the proposed system reduces these nine sources to only one: the battery car. The topology also permits full regenerative braking working as a three-level converter. The proposed system is intended for application in electric vehicles from power ratings up to 150 kW. Simulations and experimental results show the feasibility to implement this "one-source" multilevel system.

Elite sports are one of the keys to developing sports as enshrined in the Sports Law. In this law, sport is positioned as an instrument for national development. However, it is more dominated by the sports development paradigm, even though Indonesia's sports achievements have significantly developed in several international sports competitions. It is contributed through the coaching factor through sports training education from an early age under the auspices of sports education at the school level. However, the impact has not been able to influence other aspects of national development more broadly. It has become a gap between what is stated in the Sports Law and practice in the field. Therefore, this research aims to examine the implementation of elite sports policies as part of the Sports Law to realize development through sports. To achieve the objectives of this study, we designed eleven semi-structured interview indicators based on the essence of the elite sports section of the sports law. This study found that the implementation of applied elite sports policies was close to conformity with the sports law. However, on the other hand, there are still shortcomings and inequities in several aspects. Inequality in several aspects occurs due to a lack of understanding of the importance of the role of sport as an instrument of national development. Therefore, the government as a stakeholder must immediately act decisively to deal with the problems. The implications of this research can be considered for evaluating the implementation of policies that will be implemented in the future/

In this interview, José van Dijck distinguishes the concept of deplatformization from deplatforming and platformization. It describes the phenomena of the systematic pushing back of controversial platforms and their communities to the edge of the platform ecosystem, dominated by mainstream platforms (such as Google, Apple, Facebook, Amazon, and Microsoft). Deplatformization further demonstrates the hierarchical power relations within the global platform ecosystem and the complexity of platform governability. From the European perspective, van Dijck argues that public values and public institutions should play more active role in platform governance. The recent Russia–Ukraine war also indicates the vulnerability brought by such co- and inter-dependence on American platforms.


Purpose: the aim of the present study is to evaluate the intra- and postoperative complications following unicondylar knee arthroplasty and subsequent outcome. Material and methods: For the period from 2008 to 2018, we operated on 450 patients with isolated osteoarthritis of the knee joint. In the majority of cases, patients had arthrosis of the medial compartment of the joint due to antero-medial osteoarthritis or osteonecrosis and, in smaller percentage, osteoarthritis in the lateral part of the joint. Results: Various complications were registered which we divided into intraoperative and postoperative, monitoring during the follow-up of patients. Intraoperative include fracture of the tibial plateau during implantation of the component, partial resection of the intercondylar eminence during the preparation of the tibial plateau, incorrect hole placement in the femoral condyle, which led to malalignment positioning of the femoral component in varus or valgus, resection of more bone substance from the tibia leading to subsidence of the implanted component. The postoperative complications include: aseptic loosening, polyethylene wear, impingement, progression of osteoarthritis in the opposite part of the knee joint, periprosthetic infection and arthrofibrosis. Conclusion: Unicompartmental knee arthroplasty is a minimally invasive procedure for the treatment of isolated osteoarthritis of the knee joint and is associated with excellent and good long-term results. Complications could be reduced by using a meticulous surgical technique, selection of suitable implants and last but not least proper indications for surgery.


One of the experiments made possible by the trapping and cooling of a single atom is to observe the quantum jumps to a metastable state in the atom by monitoring the resonance fluorescence of a strong transition in which at least one of the states is coupled to the metastable state. When the atomic electron moves to the metastable state, the fluorescence from the strongly driven transition disappears. When the electron drops back into the strongly driven transition, the fluorescence abruptly returns. Statistical analysis of these random interruptions to the fluorescence signal implies photon antibunching in the emission of the weak photon.


Extracorporeal shock wave lithotripsy (ESWL) is one of the treatments for sialolithiasis without surgical excision. ESWL applies for a patient who is in primary condition of sialolith internal submandibular gland. As the device of ESWL, there are EDAP LT-01 and EDAP LT-02. LT-01 is a former device and LT-02 is a improved device. These device like LT-01 and LT-02 make ESWL treatment more effective, especially, a improved device LT-02. LT-02 has been already used in urology, but there are not many reported about using LT-02 in silolithiasis case. However, LT-02 gives the operation promptly, makes the angle of focusing exactly, and shows a precise of echo imaging. All the reasons have proven that LT-02 has better effectual device on the lithotripsy than LT-01 in the field of urology.This report is our experiment about ESWL for sialolith internal submandibular gland using LT-02. We experience with a client who is 26 year-old female. She complains of the pain for swelling in the left side of digastric triangle. She has the treatment of ESWL and is recovered from her chief complain. As a result of our experiment, we think that ESWL using LT-02 has more effectual device for the treatment of sialolith internal submandibular gland than a former device LT-01.


A multiple dose regimen is a concept that is used for certain diseases as arthritis, heart diseases etc. It is used to increase the therapeutic activity and clinical efficacy of the drugs. Drugs are usually used in single doses to produce acute effect but in cases where chronic affect is required multiple dosage regimen is required. Designing the dosage regimen and maintaining the drug concentration in blood plasma after administration are the primary goals to achieve safety and efficacy. That is to maintain drug concentration in therapeutic window. Moreover, the IV infusion and continuous IV diffusion is reviewed.

In this study, highly carbapenem-resistant Pseudomonas aeruginosa (h-CRPA) 18102011 [the minimum inhibitory concentration (MIC) value of carbapenem antimicrobial imipenem (IP) for h-CRPA is 4,096 μg/mL] was isolated from the bile of an intensive care unit (ICU) burn patient in China, and genomic sequencing revealed a complete genome. The genome's molecular characteristics were analyzed to assess the genetic environment of blaKPC-2 and blaVIM-2. Average nucleotide identity (ANI) comparisons were used for precise species-level identification, while serotyping, multi-locus sequence typing, and the identification of acquired resistance genes, and virulence genes were also carried out. The h-CRPA 18102011 strain carrying blaKPC-2 and blaVIM-2 was identified as strain ST2374 and the O4 serotype. Virulence genes (plcH, exoST) and resistance genes (aph(3')-IIb, aac(6')-Ib-cr, ant(2'')-Ia, blaOXA-396, blaPAO, blaKPC-2, blaVIM-2, blaPER-1, sul1, catB7, qnrVC6, fosA) were both identified in the genome. In addition, the IncpRBL16 type mega-plasmid pP2011-1 carrying blaVIM-2 and the IncP6 type plasmid pP2011-2 carrying blaKPC-2 were identified in the strain. The genetic environment of blaVIM-2 and blaKPC-2 was specifically evaluated to assess their origins. blaVIM-2 was located in the region of In2075 (a novel type 1 integron) that was inserted into plasmid pP2011-1, this plasmid contained 3 novel recombination sites, as well as the typical recombination site 2 (umuC) observed for IncpRBL16 type plasmids. However, the core module Tn3-ISKpn27-blaKPC-ΔISKpn6 was identified as the blaKPC-2 platform in plasmid pP2011-2. Conjugation experiments revealed that the plasmids pP2011-1 and pP2011-2 of the h-CRPA 18102011 strain could be transferred into Escherichia coli with a conjugation transfer efficiency of 10-6. The E. coli transconjugant carried blaKPC-2 and blaVIM-2 from the donor and the MIC value of IP to the E. coli transconjugant was 4,096 μg/mL, which was the same as observed for the donor. Overall, this study revealed the molecular characteristics of a VIM-2 and KPC-2-co-producing strain that was typed as O4 and ST2374. The continuous monitoring of bacteria, such as the strain investigated here, that co-harbor different types of carbapenemase genes is critical for preventing the spread of these genes.


The known mycoplasmas categories separated from goats and sheep were listed,and the pathogenicity and effect during diseases happening of these mycoplasmases were summarized.


This paper considers the problem of embedding Knowledge Graphs (KGs) consisting of entities and relations into low-dimensional vector spaces. Most of the existing methods perform this task based solely on observed facts. The only requirement is that the learned embeddings should be compatible within each individual fact. In this paper, aiming at further discovering the intrinsic geometric structure of the embedding space, we propose Semantically Smooth Embedding (SSE). The key idea of SSE is to take full advantage of additional semantic information and enforce the embedding space to be semantically smooth, i.e., entities belonging to the same semantic category will lie close to each other in the embedding space. Two manifold learning algorithms Laplacian Eigenmaps and Locally Linear Embedding are used to model the smoothness assumption. Both are formulated as geometrically based regularization terms to constrain the embedding task. Two lines of embedding strategies are tested, i.e., strategies based on latent distance models and strategies based on tensor factorization techniques. We empirically evaluate SSE on two benchmark tasks of link prediction and triple classification, and achieve significant and consistent improvements over state-of-the-art methods. The results demonstrate the superiority and generality of SSE.


The high-speed deformation behavior of friction stir-welded thin sheets in AA6082-T6 aluminum alloy, under biaxial balanced stretching, was investigated by means of a hemispherical punch test carried out using direct tension-compression Split Hopkinson Bar. The friction stir welding process was performed on thin sheet blanks using a pinless tool; the rotational and welding speeds were kept constant during process. The dynamic tests were carried out, with a punch speed of 4500 mm/s, at different punch stroke values until failure of the friction stir welded sample. It was seen that failure occurs along the welding line at a dome height about 11% higher than that at the onset of necking. Fractographic analysis shows that deformation is localized in the fracture zone. The results were compared with those obtained on friction stir welded blanks deformed under quasi-static condition in order to evaluate the influence of the loading rate on the weld deformation and fracture mechanisms. It was shown that joints deformed under dynamic loading condition are characterized by a dome height at the onset of necking significantly higher than the one measured under quasi-static condition.


Title of Dissertation: BROWNGIRL NARRATIVES: EXPLORING COMING OF AGE IN THE GOLDEN ERA OF HIP HOP (1986-1996) Melissa Kim Chae Reddy, Doctor of Philosophy, 2013 Dissertation Directed By: Associate Professor Psyche Williams-Forson Department of American Studies "Browngirl Narratives" seeks to gain a clearer understanding of what we can learn from the textual evidence about the experiences of browngirls who came of age during the post-civil rights Golden Age of Hip Hop (1986-1996) by examining the contemporary literature, film, social media and music produced by and about these black women. It is an inquiry into the ways in which browngirls who came of age in the United States1 negotiate the dominant scripts that exist in their lives––literature, music, film, television and the Internet––to create and craft their own stories. The aim here is to utilize an interdisciplinary, black female-centered framework to fully problematize phenomena such as self-creation, empowerment, and sexual exploration in the lives of black women who came of age during the approximate ten year period of 1986-196. This study is an examination of black female bidungsromane–– black female cultural texts which illustrate the coming of age and/or development processes. Additionally it is an investigation into what we can learn about the ongoing 1! The United States and its territories such as Guam, Northern Mariana Islands, Puerto Rico and U.S. Virgin Islands, American Samoa, U.S. Minor Outlying Islands. individuation processes for post-civil rights browngirls by engaging texts produced by and about these women. "Browngirl Narratives," examines various literary, visual and aural texts by and/or about women of African descent that explore coming of age in the lives of browngirls who came of age in Golden Era. This project will show you pieces of their narrative by carefully examining the hidden scripts amongst Ntozake Shange's choreopoem, for colored girls who have considered suicide| when the rainbow is enuf; Tyler Perry's feature film adaptation, For Colored Girls and the dialogue which surfaced as a result; the life, work and political consciousness of musical artist Erykah Badu, and; social media texts such as blogs and online commentary. The selected narrative texts about browngirls can be unpacked and analyzed using the bildungsroman as a lens with which to view concepts of selfdiscovery—"tracing the development of complex and multidimensional" browngirls, exploring "who she is and how she became that way." This study seeks to understand what these stories reveal about the journey toward a self-defined identity for browngirls marginalized by race, gender, class and sexuality coming of age in the mid-1980s to mid-1990s. What can the cultural texts tell us about how their experiences growing up during this particular period of time shape their sense of love relationships, family, community, and the self? How are concepts like black female resistance and black female empowerment negotiated in the lives of black women of the Hip Hop generation? The research discloses important overlooked narratives—"meaningful and endearing stories about their experiences that are not solely focused on heterosexual romance"—in addition to hidden transcripts or subtexts that reveal important phenomena for this particular group of women in terms of identity construction, black female representation and sexuality. BROWNGIRL NARRATIVES: EXPLORING COMING OF AGE IN THE GOLDEN ERA OF HIP HOP


There is a strong pharmacological contribution to the book which classifies receptors, deals with their endogenous ligands and looks for new and selective EAA antagonists. Considerable progress towards selective NMDA antagonists is reported, including an account of the orally active MK 801. There are other sections of the book which consider quisqualate and kainate receptors, although progress towards finding their selective antagonists have been less successful. Since EAA's predominate at the insect neuromuscular junction, current work on spider venoms may prove productive in this area (see the chapter by Jackson et al. ), while the development of tritiated ligands for quisqualate and kainate receptors should further aid in the search for selective antagonists. There is some mention of the new class of drugs, the benzomorphans which produce PCP-like behavioural effects. It is suggested that these compounds antagonize the NMDA receptor and produce anticonvulsive and anxiolytic effects which are not blocked by naloxne (see the chapter by Lodge et al.). However, others believe the sigma-opiate receptors are separate from the NMDA-type receptor, since antagonizing the sigma-opiate receptor has little effect on the NMDA type receptor, and therefore have a site of action distinct from that of competitive NMA antagonists (Lehmann). The clinical implication of EAAs is covered in some detail, especially in the context of neuronal cell loss resulting from ischaemia, hypoglycaemia, epilepsy and Alzheimer's disease (Olney). There is even a suggestion that psychoses may stem from hypofunction of the EAA transmitter system. This is based on the findings that CSF levels of glutamate are low in schizophrenics and that sigma opiates and dissociative anaesthetics, which powerfully antagonize EAA transmission, have potent psychomimetic properties. There are further sections on EAAs as both subcortical and cortical synaptic transmitters, and although the chapter on synaptic transmission and plasticity in the hippocampus (Collingridge et al.) briefly touches upon long-term potentiation (LTP) little is mentioned on LTP and learning. The publishers are to be congratulated for getting the book in press so soon after the congress (July 1986). However, in being a 'state of the art' publication, it suffers from being fragmented in presentation, and more like a series of short communications extracted from journals. I suppose this is inevitable with almost 200 contributors. Unfortunately no attempt is made to draw information together, state objectives or even present a background review to each section. Perhaps this is the price we have to pay in the rush to disseminate information. One is left with the view that there is little time for critical thinking and the editors are more than satisfied to have received their camera-ready reports on time for rapid publication. It is all very well for books to compete with journals when papers in the latter are delayed subject to peer review. A few extra weeks of editing could likewise have benefitted the quality of this publication.


goal: the paper compares the muscle power features of the treadmill running and court running with EMG record.Method: 11 middle and long distance race athletes are tested for two days with the speeds of 10,12,14,16 and 18km/h on the treadmill and court respectively.Each test lasts for 6 minutes with 10 minutes intervals.The portable megawin ME-6000 myoelectricapparatus was used to record the EMG changes of their lower limb muscle groups.The paper reveals that the treadmill running with 5% slope can be simulated as the court running and the 10% slope can give more stimulation to the lower limb muscles.There are more demand on the shinbone muscle in treadmill running than court running while the slope and the speed of the treadmill has little influence on the demand of the sports units.


The land circulation has been a universal phenomenon in rural areas,but the land circulation has the direct relationship with the economic return,and the circulation is between the relatives and friends and has short effects.The circulation is the consequence of the initial developing of the rural social security system,and directly affected the course of agriculture industrialization.Improving the rural social security system and promoting the rural land circulation institutionalization are the inevitable demand of the improving the course of agriculture industrialization.


The ternary Goldbach conjecture, or three-primes problem, asserts that every odd integer $n$ greater than $5$ is the sum of three primes. The present paper proves this conjecture.
Both the ternary Goldbach conjecture and the binary, or strong, Goldbach conjecture had their origin in an exchange of letters between Euler and Goldbach in 1742. We will follow an approach based on the circle method, the large sieve and exponential sums. Some ideas coming from Hardy, Littlewood and Vinogradov are reinterpreted from a modern perspective. While all work here has to be explicit, the focus is on qualitative gains.
The improved estimates on exponential sums are proven in the author's papers on major and minor arcs for Goldbach's problem. One of the highlights of the present paper is an optimized large sieve for primes. Its ideas get reapplied to the circle method to give an improved estimate for the minor-arc integral.


Composite lymphoma (COM) is an uncommon pathological diagnosis in which two or more distinct lymphomas are encountered within a single tissue sample. In contrast, discordant lymphoma (DIS) represents two or more distinct histologies encountered concurrently at two or more separate anatomic sites.


: Older adults suffer the majority of cancer diagnoses and deaths, and also make up the majority of cancer survivors; however, there is little support in the literature for evidence-based clinical management of older patients with breast cancer. This is to a great extent due to the fact that older adults are commonly excluded from most clinical trials. Thus, an appropriate standard of care for older patients has not been established. Treatment needs to be individualized, taking into account patient health status and preference in addition to the anatomical and biological staging. Employing a comprehensive geriatric assessment (CGA) may be advantageous in older patients. This approach formulates a cancer treatment plan after employing a multidisciplinary approach to evaluate patient vulnerability from several different angles. One aim is to predict adverse events of chemotherapy and identify geriatric problems in advance so that extra support and modified treatment can be provided. As well as overtly adverse events, health-related quality of life (HRQoL) is also important in older patients, due to the negative effects of chemotherapy. For decision making about adjuvant treatment in older patients, we should know that older adults differ from their younger counterparts in terms of willingness to trade survival for current HRQoL. Here, current adjuvant therapies in older patients with breast cancer are reviewed and discussed regarding how to approach decision making.


In this letter, we propose a shared adaptive packet loss concealment scheme for the high quality guaranteed Internet telephony service which connects multiple users. In order to recover packet loss efficiently in the all-IP based convergence environment, we provide a robust signal recovery scheme which is based on the shared adaptive both-side information utilization. This scheme is provided according to the average magnitude variation across the frames and the pitch period replication on the 1-port gateway (G/W) system. The simulated performance demonstrates that the proposed scheme has the advantages of low processing times and high recovery rates in the all-IP based ubiquitous environment.


Gold nanoparticles (AuNPs) were synthesized under ambient conditions from chloroauric acid in aqueous solution at pH 4. Tannin-rich extract from Xylocarpus granatum bark was used as both reducing and capping agent, rapidly converting Au (I) salt to AuNPs. Transmission electron microscopy showed the as-prepared AuNPs to be predominantly spherical, with an average diameter of 17 nm. The AuNPs were tested for catalytic reduction of Congo red (CR), a carcinogenic azo dye, in aqueous sodium borohydride solution. Cotton samples were coated with the AuNPs, taking on a reddish-purple color. The samples showed significantly reduced tearing strength after coating, though tensile strength was unaffected. UV-visible spectroscopy was used to determine the dye concentration in the water. CR degradation was observed only when AuNPs were present, and the efficiency of degradation was strongly linked to the AuNP loading. The AuNP-coated fabrics left only a 4.7% CR concentration in the solution after 24 h and therefore promise as a heterogeneous catalyst for degradation of CR in aqueous solution.


A mathematical model is developed to determine the steady-state electric current flow through in non-homogeneous isotropic conductor whose shape has a three-dimensional hollow body. The equations of the Maxwell's theory of electric current flow in a non-homogeneous isotropic solid conductor body are used to formulate the corresponding electric boundary value problem. The determination of the steady motion of charges is based on the concept of the electrical conductance. The derivation of the upper and lower bound formulae for the electrical conductance is based on Cauchy-Schwarz inequality. Two numerical examples illustrate the applications of the derived upper and lower bound formulae.


In this paper we report an analogue for the vacuum state in classical field theory and its Planckian nature with respect to uniformly accelerated observers. When a real, monochromatic, mode of a scalar field is Fourier analyzed with respect to the proper time of a uniformly accelerating observer, the resulting power spectrum consists of three terms none of which have a simple classical meaning. Specifically, the three terms are (i) a factor (1/2) that is typical of the ground state energy of a quantum ascillator, (ii) a Planckian distribution N(Ω) and — most importantly — (iii) a term , which is the root mean aquare fluctuations about the Planckian distribution. It is the appearance of the root mean square fluctuations that motivates us to attribute a "thermal" nature to the power spectrum. Such a power spectrum also arises when we Fourier analyze a real, monochromatic, plane electromagnetic wave in the frame of a uniformly accelerating observer. We also present a model of a detector whose response is the Fourier spectrum of the field with respect to its proper time, which illustrates that it should, in principle, be possible to physically measure the power spectrum we have obtained. These results show that some of the "purely" quantum mechanical results might have a classical analogue.


ALL SHE WAS WORTH is search for a woman on the run. The trouble is, the life she left behind doesn't seem to have been her own. What would it take to cut through the elaborate red tape Japan uses to keep tabs on its citizens, and become a different person? Maybe murder?


Anthropogenic alterations to Iowa's landscape have greatly altered lotic systems with consequent effects on the biodiversity of freshwater fauna. Ictalurids are a diverse group of fi shes and play an important ecological role in aquatic ecosystems. How- ever, little is known about their distribution and status in lotic systems throughout Iowa. The purpose of this study was to describe the distribution of ictalurids in Iowa and examine their relationship with ecological integrity of streams and rivers. Historical data (i.e., 1884-2002) compiled for the Iowa Aquatic Gap Analysis Project (IAGAP) were used to detect declines in the distribution of ictalurids in Iowa streams and rivers at stream segment and watershed scales. Eight variables characterizing ictalurid assemblages were used to evaluate relation- ships with index of biotic integrity (IBI) ratings. Comparisons of recent and historic data from the IAGAP database indicated that 9 of Iowa's 10 ictalurid species experienced dis- tribution declines at one or more spatial scales. Analysis of variance indicated that ictalurid assemblages differed among samples with different IBI ratings. Specifi cally, total ictalurid, sensitive ictalurid, and Noturus spp. richness increased as IBI ratings increased. Results in- dicate declining ictalurid species distributions and biotic integrity are related, and manage- ment strategies aimed to improve habitat and increase biotic integrity will benefi t ictalurid species.


In the context of theories where particles can have different limiting velocities, we review the running of particle speeds towards a common limiting velocity at low energy. Motivated by the recent OPERA experimental results, we describe a model where the neutrinos would deviate from the common velocity by more than do other particles in the theory, because their running is slower due to weaker interactions.


This paper presents arguments purporting to show that von Neumann's description of the measurement process in quantum mechanics has a modern day version in the decoherence approach. We claim that this approach and the de Broglie-Bohm theory emerges from Bohr's interpretation and are therefore obliged to deal with some obscures ideas which were antecipated, explicitly or implicitly and carefully circumvented, by Bohr.


Sarcopenia has been one of the mainly public health problems in many countries.In the modern society,people are caring more than before about quality of life and health,and they spend a lot on the age-related diseases.With the rapid increase of the aged population in China and the whole world,the prevalence of Sarcopenia will increase dramatically.How to deal with the great cost due to Sarcopenia and its count measures are important social problems.


The effects of the Al2O3 liquid particles on the plasmadynamics and the generator performance of a large-scale pulsed MHD generator "Sakhalin", operated with a solid propellant and an MHD channel of 4.5m, having demonstrated the electric power output of 510MW, are numerically investigated by using the time-dependent two-dimensional analyses with the assumption of a two-phase flow. The Harten-Yee upwind TVD scheme is implemented for gas-phase equations, while the Galerkin finite element method is used to obtain the electrodynamical distributions. The liquid-phase is treated as a particle. For the experimental channel voltage of 2550V, in both cases of the particle diameter of m µ 15 and m µ 5 , the core flow experiences a smooth deceleration and the gasdynamical and electrodynamical distributions become almost symmetric in the Faraday direction. For the channel voltage of 1400V, in both cases of the particle diameter, a strong MHD interaction induces a boundary-layer separation in the MHD channel. The boundary-layer separation becomes very large because the liquid particles can follow the behavior of gas-phase in the case of the particle diameter of m µ 5 , while the growth of the boundary-layer separation is restricted because the liquid particles transfer the momentum into the separation region in the case of the particle diameter of m µ 15 . The electrical loss near the anode is quite large in the case of the particle diameter of m µ 5 , while it becomes much smaller in the case of the particle diameter of m µ 15 .


In order to evaluate the effect of irrigation termination and genotype on chlorophyll index (SPAD), relative water content, electrolyte leakage and seed yield in spring safflower, an experiment was conducted, in a spilt plot arrangement based on randomized complete block design with four replications at Research Farm, Faculty of Agriculture, the University of Birjand, during 2008. Irrigation regimes (full irrigation (whole season irrigation), irrigation until grain filling, flowering and heading-bud) and genotypes (Mahali Isfahan (a local variety), Isfahan28 and IL111) were arranged in main and subplots, respectively. Results showed chlorophyll content, relative water content, cell membrane stability and seed yield were influenced by irrigation termination. Provided that with terminating irrigation at an earlier stage, an increase in electrolyte leakage and reduction in relative water content and seed yield was observed in plants. There were negative relations between electrolyte leakage from plants leaf cells and seed yield. Plants which experienced irrigation termination in an earlier growth stage, suffered more damage to their cell membranes, leading to depression of their production potential. Based on the results, Mahali Isfahan and Isfahan28 can be introduced as drought resistant genotypes, because of their lower electrolyte leakage and higher relative water content. But, in general, Mahali Isfahan had the highest seed yield due to its nativeness and high adaptation to arid conditions southern of Khorasan, and therefore this genotype suggests for planting in the region.


The ability of rainfall to promote soil disaggregation and transport depends on its intensity and distribution over time, allowing proper soil and water management practices in order to minimize their effects in and outside food production fields. The objective of this study was to verify the intensity of the spatial and temporal distribution of rainfall erosivity in Goias and Federal District states using historical series of rainfall data available at the National Institute of Meteorology (Inmet) from 1986 to 2017. Rainfall erosivity (EI) for Goias and Federal District were estimated using the modified Fournier index. Annual average for factor R were obtained by the sum of the EI in the 12 months of the year. Data were placed to descriptive analysis and classification according to their erosive capacity. The annual mean of the factor R for the study region was 8,834±5.2 MJ mm ha -1 h -1 ano -1 , being classified as a strong erosive potential. However, considering the territory, its intensity in Goias and DF varied from very strong to moderate throughout the year, indicating the need to adopt a conservationist practice that protects the soil from the kinetic energy of rainfall. It is concluded, therefore, that the intensity and distribution of the rainfall erosivity fluctuate both between the municipalities of Goias (from 4.514±2.5 to 11.215±1.8 MJ mm ha -1 h -1 year -1 ), and throughout the year (from 180±1.5 to 1.519±4.4 MJ mm ha -1 h -1 month -1 ).


A method of image zoomingin is presented in this paper. It is based on Bzier interpolation surface. First, it constructs a piecewise bicubic Bzier interpolation C1 surface for each color component of a digital image, and then, samples the surface with different sampling rate to zoom in. The experimental results show that the method can improve the quality of zoomed image greatly.


Fermions become polarized in a vorticular fluid due to spin-vorticity coupling. Such a polarization can be calculated from the Wigner function in a quantum kinetic approach. Extending previous results for chiral fermions, we derive the Wigner function for massive fermions up to the next-to-leading order in spatial gradient expansion. The polarization density of fermions can be calculated from the axial vector component of the Wigner function and is found to be proportional to the local vorticity $\omega$. The polarizations per particle for fermions and anti-fermions decrease with the chemical potential and increase with energy (mass). Both quantities approach the asymptotic value $\hbar\omega/4$ in the large energy (mass) limit. The polarization per particle for fermions is always smaller than that for anti-fermions, whose ratio of fermions to anti-fermions also decreases with the chemical potential. The polarization per particle on the Cooper-Frye freeze-out hyper-surface can also be formulated and is consistent with the previous result of Becattini et al..


Objective: Comprehensive evaluation was used to compare the clinical treatment effect of McKenzie therapy with that of traditional massage on the low back pain patients.Method: Seventy low back pain patients(the reducible derangement syndrome) were involved in our study.They were divided into two groups: In the first group,35 cases received McKenzie therapy;in the second group,other 35 cases had traditional massage.Before each treatment session,we recorded the pain scores using visual analogue scale(VAS),the ROM of the lumbar spine and the symptom of radiation pain of the leg.Treatment effective rate was collected and recorded.After ward,we used the model of comprehensive evaluation to compare the effect between the two approaches.Result:Before the treatment,the VAS scores were 7.84±1.26 and 7.67±1.12 respectively in patients receiving McKenzie therapy and traditional massage,there was no significant difference in the scores of VAS between the two approaches.A significant difference was found in the McKenzie when compared with the traditional massage in each session for total 5 sessions(P0.05).The ROM of lumbar and the radiation pain of leg were better in McKenzie than in traditional massage(P0.01).By using the comprehensive evaluation,the comprehensive index of the two groups did not demonstrate a significant difference before session(Z=0.07,P=0.94).To compare the two groups after 5 times of treatments,the group of McKenzie was better than the group of traditional massage as(Z=7.13,P0.001),which had statistical significance.Conclusion:The McKenzie therapy is a better method than the traditional massage to treat the low back pain.


Objective To explore the impact of polypropylene mesh on the vas deferens in inguinal hernioplasty.Methods The SpomaTex polypropylene mesh manufactured by Bard Corporation was used to protect the spermatic cord along with the vas deferens in hernia repair.Results No complications including tissue adhesions of the spermatic cord and male infertility were found in inguinal hernioplasty with a SpomaTex or a conventional mesh patch.Conclusions In the short-term follow-up,no complications such as tissue adhesions of the spermatic cord and male infertility are found.However,some cases of polypropylene mesh induced-infertility are reported abroad,to which attention should be paid clinically.The cooperation among different departments should be enhanced to follow these surgical patients chronically.


A strong incentive for our work in physiologic optics has been to help prepare the way for a more extensive use of hygienic measures in the care and treatment of the eye. The subject of hygiene has been built up in the attempt to preserve and restore normality of function through regulation of the conditions under which the organ functions. In relation to the care of the organs of the body the growth of hygiene has been rapid. In relation to the sense organs, however, its progress, it would seem, has suffered perhaps undue retardation. Whether this situation is intrinsic or merely marks a stage in the development of the subject time alone can tell. In the case of the eye, at least, it would seem that hygiene can be made to play a much more important part than it now does, that is, that the care and treatment of


The main reason for pavement disease is vehicle load. We did lots of experiments based on a road reconstruction project and then through the static analysis of road surface deflection and stress with ANSYS,we can get maximum position of road surface deflection and variation tendency of stress. Taking into account the movement characteristics of the vehicles on the road, we got the maximum displacement and stress variation rules with time through the dynamic analysis of vehicleroad system. The research results will provide a theoretical basis for the prevention of pavement disease.


The purpose of this exploratory study was to analyze the perceptions of healthcare consumers in accessing their health information via provider portals, when using personal health records, and through the release of information process. Availability of electronic health records and consumers' electronic access to their health information has changed dramatically since the enactment of the Health Information Technology for Economic and Clinical Health (HITECH) Act in 2009. Results indicated that only 10 percent of consumers were charged for their health information and 82 percent reported that they took advantage of their provider's portal if it was available. Less than half (49.1 percent) of the consumers surveyed reported that they maintained a personal health record. These findings indicate that healthcare consumers are now requesting access to their health information in electronic form and are accessing their information through patient portals.


A [Formula: see text] net is a trivalent decoration made by alternating squares [Formula: see text] and octagons [Formula: see text]. It can cover either a cylinder or a torus. In this paper, we determine rhomboidal [Formula: see text] toris which are Cayley graphs.


A high efficiency of thermoelectric conversion can be achieved by using materials with a maximum figure of merit Z, i.e. materials with a high Seebeck coefficient S, high electrical conductivity σ and low thermal conductivity K. Investigations of transport phenomena in alloys of the (TlBiS2)1−x(2PbS)x system have shown that in solid solutions of type (A3B5C 26) 1−x (2A4B6) x cation substitution according to the scheme 2A4(+2) → A3(+1) + B5(+3) leads to a strong decrease in lattice thermal conductivity KL. In an area (X = 0.50) of the KL = f(C) curve the lattice part of the thermal conductivity of (TlBiS2)1−x(2PbS)x alloys decreases to 0.26 W m−1 K−1, which is approaching the theoretical minimum. As a result, the dependence of the thermoelectric figure of merit on composition Z = f(C) of alloys of the (TlBiS2)1−x(2PbS)x system passes through a maximum in the area X = 0.50, exceeding by ∼25% the respective value of Z for lead sulfide at room temperature.


Among the music printers of the Renaissance, Jacques Moderne remains an enigmatic person. Throughout his career, he continued to work as a generalist printer, producing books on very diverse subjects, but his most important undertakings were clearly his musical editions, the material for which he mainly obtained via Italian connections. Political disorders having momentarily put a stop to musical printing in Italy, Jacques Moderne was able to turn Lyon into one of the main centres of music printing, by crystallizing in his first series the Franco-Flemish repertoire His bestknown anthology, called Motteti del Fiore, is made up of the eight books published between 1532 and 1542. Comprising overall 228 pieces by 64 composers, the earliest collections include some well-known compositions of the times, whereas from about 1539 there is a noticeable turn toward some minor French composers. These frequently constitute the only remnants of the work of these composers. This article attempts to shed new light on the titles and dates in this series. Jacques Moderne, unlike his contemporaries in France or in Germany, gave his work an Italian title. The term Motteti del Fiore appears only on the books for four voices and never on the five-voice ones. Curiously, two of the four books for four voices are not dated. After examining the typographic material, it is quite clear that Moderne printed his books as companions (each one for four voices coupled with one for five voices). In addition, the state of certain of the woodcut initials indicates that the Secundus liber cum quatuor vocibus was not printed in 1532 (the dating given by RISM and S. Pogue) but in 1538. Also, the Quartus liber cum quatuor vocibus was certainly printed as a companion to the Quintus liber cum quinque vocibus in 1542. The wording of the colophons and the presence of composers fits in perfectly with this new sequencing.


Objectives To evaluate the analgesic yield of thoracic epidural (TE) analgesia using bupivacaine in combination with dexamethasone, clonidine versus fentanyl for thoracotomy patients. Patients and methods Sixty patients were divided into four equal groups, which received TE analgesia immediately at end of surgery during skin closure using bupivacaine either alone (C group) or in combination with dexamethasone (S1 group), clonidine (S2 group), or fentanyl (S3 group). Postoperative (PO) pain was measured using a visual analogue scale (VAS); rescue analgesia (50 mg mepridine) was given when a patient had a VAS score of 40, and the duration of analgesia and the total mepridine doses consumed were determined during 24-h postoperatively. Verbal rating scores were used for the evaluation of PO sedation and nausea and vomiting (PONV). Results The mean duration of analgesia was significantly longer in the study groups compared with group C, with a significantly longer duration in the S1 group compared with the S3 group. The mean 24-h cumulative pain VAS score and the total PO rescue analgesia consumed were significantly lower in the S1 group compared with the other groups and in the S2 group compared with group C. Both S2 and S3 groups showed significantly higher frequency of higher sedation scores compared with the C and S1 groups. The frequency of patients who had a PONV zero score was significantly higher in the S1 group compared with the other groups, with a nonsignificant difference among the other groups. Conclusion TE analgesia using bupivacaine with clonidine or dexamethasone is an efficient therapeutic modality for post-thoracotomy pain. Dexamethasone as an adjuvant provided more prolonged PO analgesia, with a reduction of rescue analgesia consumption without PO sedation, and spares the use of antiemetics for PONV that was minimized in frequency and severity.


The authors, in reviewing the tumors of the central nervous system in the pathological collection of the Henry Ford Hospital, studied one tumor which is so rare in incidence and point of origin as to merit a place in medical literature. According to Bailey and Cushing,' neuroepitheliomas are tumors composed of prnmitive spongioblasts characteristically arranged in rosettes about central canals, the canals lined by a cuticular membrane bearing blepharoplasten and presenting cilia upon its inner surface, and the outer extremities of the cells fading away as tails into the surrounding tissue. These authors state that the tumor commonly arises in the spinal cord and the retina. Flexner,2 Wintersteiner I and others have described the retinal type, while Schlapp,4 Rosenthal,5 Thielen and Zinn,6 and others have described the spinal cord type. Bailey and Cushing in their series of 254 classified intracranial tumors had no examples of neuroepithelioma. However, in a subsequent article, Bailey7 reported a case of neuroepithelioma of the left lower frontal lobe. The histological picture in this case corresponds very closely to the case reported here, as is shown by the photomicrographs and by sections of the tumor which we have been permitted to examine. Just as we were about to submit this article for publication another case of neuroepithelioma was drawn to our attention, a very recent case of tumor involving the fourth ventricle. This case was operated upon by Dr. Harvey Cushing and as yet has not been fully studied. However, the sections which we have been fortunate enough to examine seemed typical of this pathological entity. It is also very interesting to note that the inner ends of the cells forming the rosettes bore definite cilia. This is undoubtedly due to the fact that the sections examined were from a specimen removed at operation and fixed immediately after its removal. Until this case is more * Received for publication January 4, I929.


The Retinal nerve and the Optic Nerve Fibre Layer (RNFL) are damaged by an eye disease called as Glaucoma, eventually leading to blindness if not treated in time. When this happens, fluid builds up in the retina's anterior region, which raises eye pressure and damages the optic nerve. Glaucoma results in irreversible vision loss due to increased intraocular pressure (IOP) and optic nerve damage. Ophthalmologists use expensive and time-consuming medical techniques such as HRT and OCT. As a result, to detect glaucoma efficiently and quickly, an automatic computer-aided system is required. The optic cup and optic disc are the primary characteristics that assist in the diagnosis of glaucoma. As a result, segmentation of the optic disc and optic cup properly is critical in detecting the disorder. In this paper, results are obtained using an adaptive method that takes as input raw images, masks, and text files (CDR values). The experimental results are found to be 98% accurate. Furthermore, the proposed method is faster and has a less cost.


In a previous article, using underlying graph theoretical properties, Gouveia and Magnanti (2003) described several network flow‐based formulations for diameter‐constrained tree problems. Their computational results showed that, even with several enhancements, models for situations when the tree diameter D is odd proved to be more difficult to solve than those when D is even. In this article we provide an alternative modeling approach for the situation when D is odd. The approach views the diameter‐constrained minimum spanning tree as being composed of a variant of a directed spanning tree (from an artificial root node) together with two constrained paths, a shortest and a longest path, from the root node to any node in the tree. We also show how to view the feasible set of the linear programming relaxation of the new formulation as the intersection of two integer polyhedra, a so‐called triangle‐tree polyhedron and a constrained path polyhedron. This characterization improves upon a model of Gouveia and Magnanti (2003) whose linear programming relaxation feasible set is the intersection of three rather than two integer polyhedra. The linear programming gaps for the tightened model are very small, typically less than 0.5%, and are usually one third to one tenth of the gaps of the best previous model described in Gouveia and Magnanti (2003). Moreover, using the new model, we have been able to solve large Euclidean problem instances that are not solvable by the previous approaches. © 2004 Wiley Periodicals, Inc.


In this paper, we address the trajectory planning problem in uncertain nonconvex static and dynamic environments that contain obstacles with probabilistic location, size, and geometry. To address this problem, we provide a risk-bounded trajectory planning method that looks for continuous-time trajectories with guaranteed bounded risk over the planning time horizon. Risk is defined as the probability of collision with uncertain obstacles. Existing approaches to address risk-bounded trajectory planning problems either are limited to Gaussian uncertainties and convex obstacles or rely on sampling-based methods that need uncertainty samples and time discretization. To address the risk-bounded trajectory planning problem, we leverage the notion of risk contours to transform the risk-bounded planning problem into a deterministic optimization problem. Risk contours are the set of all points in the uncertain environment with guaranteed bounded risk. The obtained deterministic optimization is, in general, nonlinear and nonconvex time-varying optimization. We provide convex methods based on sum-of-squares optimization to efficiently solve the obtained nonconvex time-varying optimization problem and obtain the continuous-time risk-bounded trajectories without time discretization. The provided approach deals with arbitrary (and known) probabilistic uncertainties, nonconvex and nonlinear, static and dynamic obstacles, and is suitable for online trajectory planning problems. In addition, we provide convex methods based on sum-of-squares optimization to build the max-sized tube with respect to its parameterization along the trajectory so that any state inside the tube is guaranteed to have bounded risk.


The synthesis of fused tetracyclic naphthothiopyranopyranones from dihydronaphthothiopyranones I or II has been studied. Compounds I or II have been cyclised in good yield to the corresponding dioxaborin difluoride complexes III, IV, XIII and XIV by treatment with acetic or propionic anhydride and boron trifluoride etherate. These complexes and the Vilsmeier reagent reacted to produce fused tetracyclic 3-substituted naphthothiopyranopyranones V, VI, XV or XVI.

The reaction of dioxaborin difluoride complexes III or IV with dimethylthioformamide (DMTF) afforded dimethylaminovinyldioxaborin difluoride complexes IX or X. Treatment of IX or X with hydrochloric acid solution gave naphthothiopyranopyranones VII or VIII.

The reaction of VII, VIII, XV or XVI with DMTF/acetic anhydride yielded new products, which was identified as naphthothiopyranopyranthions XI, XII, XVII or XVIII.


In December 2010, the Basel Committee on Banking Supervision (BCBS) published the Basel III framework for liquidity risk regulation, which sets out two separate but complementary minimum standards for banks' funding risk – the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR). These standards aim at ensuring a higher stock of liquid assets and lower asset/ liability maturity mismatches than there were prior to the financial crisis, thereby reducing the risk of an individual bank running into liquidity problems. The proposed regulation framework represents minimum standards to be applied to internationally active banks in a uniform manner, while national regulators may apply more stringent requirements to individual institutions based on their liquidity risk profile. In January 2013, as a result of a careful assessment of the impact of the regulation framework, the BCBS agreed on a revised LCR. The Basel III liquidity standards, and in particular the LCR, are expected to interact with monetary policy implementation.


This paper introduces the scattering matrix for Total Internal Reflection (TIR) electro-optic switch and Spanke switch fabric. The transfer functions of the switch and switch fabric are derived through Mason's gain formula. The scattering matrix of the switch fabric is formed using star product of switch element's scattering matrices. These transfer functions can be made to analyze the responses of the switch and fabric. Finally, generic model for transfer function of 'n' port switch fabric is proposed.


This essay is a result of an ongoing study on writing and the function of the letters in Francois Truffaut's work. If his films have been quite commented and if the theme of the letter has already been analyzed, this has never been done in a systematic way. Our working hypothesis is to consider the letter – term to be understood in all its polysemy – as an essential element of the reflexive dimension of Truffaut's films which critics have never mentioned. Just like one of his masters – Hitchcock – Truffaut is both a filmmaker aimed at the general public as an author who puts into play the specificity of cinematic representation. Through his art, Truffaut also inherits from his adoptive father – Andre Bazin – the way opened by him as a thinker of cinema.


The Laser Electron Acceleration Project (LEAP) group has been conducting a proof of principle experiment on the acceleration of electrons with a pair of crossed laser beams. To date there has been no experimental verification of electron acceleration with crossed laser beams in a dielectric loaded vacuum, although the energy profile of an accelerated electron bunch has been well described by theory. The experiment is subject to unavoidable time dependent fluctuations in the independent variables. Changes in the experimental parameters can dramatically alter the beam profile incident near the focal plane of a high-resolution spectrometer located downstream from the accelerator cell. Neural networks (NNs) appear to provide an ideal tool for the positive determination of an acceleration event, being adaptable and able to handle highly complex nonlinear problems. Typical NNs under such conditions require a training set consisting of a representative data set along with ''answers'' which have been determined to be consistent with the variable state of the experimental parameters. A strategy of pattern recognition with respect to the status of independent variables can be employed to determine the signature characteristics of a laser perturbed electron bunch. Data cuts representing characteristics that were thought to be distinctive to acceleratedmore » beam profile images were implemented in the algorithm employed. Statistical analysis of the results of data cuts made on the energy profile images from the experiment is presented, as well as conclusions drawn from the results of this analysis. Finally, a discussion of future directions to be taken in this work is given including the orientation towards on-line, real-time analysis.« less


We present a minimal-point algorithm for finding fundamental matrices for catadioptric cameras of the parabolic type. Central catadioptric cameras-an optical combination of a mirror and a lens that yields an imaging device equivalent within hemispheres to perspective cameras-have found wide application in robotics, tele-immersion and providing enhanced situational awareness for remote operation. We use an uncalibrated structure-from-motion framework developed for these cameras to consider the problem of estimating the fundamental matrix for such cameras. We present a solution that can compute the para-catadioptirc fundamental matrix with nine point correspondences, the smallest number possible. We compare this algorithm to alternatives and show some results of using the algorithm in conjunction with random sample consensus (RANSAC).

This study investigates the use of hedges (mitigating expressions like I think or sort of) in the speech of learners of English at multiple proficiency levels as well as of native speakers. Hedges are used to mod erate the force of an utterance or the certainty of its content and therefore play an important role in interpersonal communication. The results of this study show that learners generally underuse hedges in comparison with native speakers, although learners at the highest proficiency level use hedges at a rate comparable to that of native speakers. The range of hedges is generally similar across levels. In both the rate and the range of hedge use, striking changes appear to take place between the second highest and the highest proficiency level. The results are discussed in terms of their importance for comparing data from different task types and discourse types.

The book is built up of four Operations Research (OR) models to facilitate the decision making process of the firm.


Resonance changer is an effective equipment to control longitudinal vibration of marine shafting.Due to the working fluid in the damping device,the longitudinal stiffness and damping of the shafting system is changed and results in vibration attenuation.For the alternation longitudinal load of the marine shafting,the working pressure in the device changes and impacts on the vibration damping effect of resonance changer.The longitudinal vibration model of ship shafting system is established based on the finite element method,introducing the nonlinear relationship of the working fluid pressure and equivalent parameters of resonance changer.The acceleration response at the shafting thrust bearing is devised with Wilson-θ method in time domain.By Fourier transform,the characteristics of longitudinal vibration response in frequency domain are also obtained.Fluid properties and structural parameters that impact on the attenuation effect are discussed


The accuracies of CAD models for suspended and inverted microstrip are examined, and new models are proposed. The models are compared over the range of 0.1/spl les/w/h/spl les/10 and for /spl epsiv//sub r/ values of 3.78 and 12.9. Of the three models examined, the Tomar and Bhartia (T&B) model is shown to be the most accurate. For /spl epsiv//sub r/=12.9 (the worst case), the T&B model shows maximum and average errors of 2.94 and 1.28% respectively over its valid range. New CAD models are presented which demonstrate significantly improved accuracy and range of convergence. For suspended and inverted microstrip, the new models demonstrate worst case errors of 0.65 and 1.02%, respectively, and average errors of 0.23 and 0.27%, respectively. Further, the new models are valid for the full 0.1/spl les/w/h/spl les/10 range, and unlike the other models, converge for the limiting cases of either complete substrate filling or a zero thickness substrate. >


Abstract This present study discusses appropriate selection of research paradigm and research strategy of socio-economic theory of organisations for organisational innovation in general, customer complaint management (CCM) in particular. Ontology and epistemology of socio-economic approach to management (SEAM) methodology, mixed quantitative and qualitative methods are proved to be consistent with the implementation of CCM in small-to-medium sized enterprises (SMEs). The research indicates how to produce and generalise theoretical and practical knowledge through abductive reasoning and early-versus-latter-stage research design for a pragmatic-oriented action research. The conceptual model highlights that CCM can positively and simultaneously impact technical innovation, economic performance and social performance. One more interesting result is that economic performance can positively affect social performance. The research process includes two five-step action plans in the early stage and empirical study in latter stage. The two five-step action plans (2015-2016 and 2017-2018) analyse customer complaints, explore the causes of customer complaints from employees' viewpoints, put forward action plans, implement action plans and evaluate organisational performance. The empirical study applies structure equation modeling, to test whether technical innovation mediates the relationship between CCM and organisational performance.

Resumen El presente estudio discute la seleccion apropiada del paradigma de investigacion y la estrategia de investigacion de la teoria socioeconomica de las organizaciones para la innovacion organizacional en general, y la Gestion de Reclamos de Clientes (GRC) en particular. La ontologia y la epistemologia de la metodologia del enfoque socioeconomico para la gestion (SEAM, en ingles) y los metodos mixtos cuantitativos y cualitativos, han demostrado ser consistentes con la implementacion de la GRC en pequenas y medianas empresas (PYMES). La investigacion indica como producir y generalizar conocimientos teoricos y practicos a traves del razonamiento abductivo y el diseno de la investigacion de etapa inicial versus etapa tardia para una investigacion de accion orientada y pragmatica. El modelo conceptual destaca que la GRC puede impactar positiva y simultaneamente en la innovacion tecnica, el desempeno economico y el desempeno social. Otro resultado interesante es que el desempeno economico puede afectar positivamente el desempeno social. El proceso de investigacion incluye dos planes de accion de cinco pasos en la etapa inicial y un estudio empirico en la ultima etapa. Los dos planes de accion de cinco pasos (2015-2016 y 2017-2018) analizan las quejas de los clientes exploran las causas de las quejas de los clientes desde el punto de vista de los empleados, presentan planes de accion, implementan planes de accion y evaluan el desempeno organizacional. El estudio empirico aplica el modelo de ecuaciones de estructura para probar si la innovacion tecnica media la relacion entre la GCR y el desempeno organizacional.

Light shift is important and inevitably affects the long-term stability of an atomic clock. In this work, considering two unbalanced branches of the spontaneous decay rate in a three-level system, we studied the frequency shifts of electromagnetically induced transparency (EIT) and coherent population trapping (CPT) clocks operating under the pulse sequence regime by numerically solving the Liouville density matrix equations. The results show that the frequency shifts are larger when the two branches of spontaneous emission rate are not equal compared to the equal case. In addition, in EIT-Ramsey, the effect of the unbalanced branches of the spontaneous decay rate and relaxations of low-energy states on the frequency shift is greater than that of Rabi frequency. In CPT-Ramsey, the relaxations of low-energy states play a dominant role in frequency shift.


Of the 242 groundnut genotypes, tested both in epiphytotic field and laboratory conditions, the genotypes viz., ICGV 90009, ICGV 86699, ICGV 86329, 91177, 91234, ICGV‐94252 and TG 26 were found promising both with low incidence of PBND besides longer incubation periods, DFSA, DLSA and IP 50%. Further, significant positive correlation was found between IP 50% vs DLSA, DFSA and final PBND (%) was negatively correlated with IP 50% and DFSA.


This work provides study and analysis of electrical interference effects of transmission lines upon nearby pipelines. The electromagnetic field coupling is a major reason of increasing the corrosion on pipeline near overhead power transmission line. The work presents physical EMF measurements on pipelines, during steady state condition. The models achieved describe the phenomenon of electrical interference in large-scale systems comprising conductors of arbitrary orientations. The types of interference between AC power transmission line and pipelines has been summarized and presented. The paper should explain important factor in order to determine the cause of corrosion initiation in a system of pipelines run parallel to over head power transmission line. The future work is concentrated on all major electrical power stations, in order to monitor/determine/reduce corrosion phenomena.


The partial differential equations governing the shaft/casing system with rubs during passage through the first several critical speeds are solved by an explicit stable finite difference scheme. The ro tational speed of the shaft is increased at a constant angular acceleration. The contact force theory is used to calculate the impacting forces and friction forces. First, the effect of the rotating angular acceleration of the shaft on the instability of the nonstationary motion with rubs is investigated. Then, the irregular changes of the deflection of the shaft, in which are found many modes of bending, and diagrams of the bending moment in rub events are depicted. The results suggest that the instability of motion in rub events could lead to struc tural shaft failure ultimately due to the unlimited increases of the bending moment and bending stress of the shaft accordingly


The importance of equity valuation in the current business environment is forced by recent trend of mergers and acquisitions. However, the business valuation can be done for a wide range of purposes. The main aim of this paper is to investigate the current valuation practice in the Czech Republic. On the basis of the expert ́s valuation reports, the paper allows overview of the purposes and methods that are used in nowadays practice. The results confirm that the change of business ownership is the most frequent reason for equity valuation in nowadays practice. For determination of company value were used mainly assets based models and discounted cash flow models in comparison with relative valuation that has only limited applicability in the Czech Republic. The analysis is focused furthermore on the inherence of financial, strategic and sensitivity analysis in business valuation process. However, from the survey it is evident that sensitive analysis does not appertain to the standard part of business valuation process and it occurs rather sporadic despite the fact that it should be routine operation. Keywords—business valuation, analysis, equity, discounted cash flow model.


In public, as well as private sectors it is inevitable to react to the versatile environment and evaluate the influence of qualitative and quantitative factors on the organization while planning complex projects, processes or/and forecasting growth. Expert evaluation, discussed in the current research paper, is one of the strategic planning tools employed as an external source of knowledge and advice. The purposes of the current research were formulated seeking to identify a full expert evaluation process, to single out obligatory stages that could impact company development, and to highlight issues that might influence the level of success of organisational change, brought by the expert evaluators as a result of the external evaluation process. Based on the analysis of theoretical sources with regards to stages, main actors and distribution of responsibilities in the evaluation process and the case study the Model of Expert-Based Evaluation Process has been developed.

Supplemental Digital Content is available in the text ABSTRACT Background: To investigate the feasibility and the value of using mitochondrial quality control (MQC)-related proteins as biomarkers in septic patients. Methods: The enrolled subjects were divided into four groups: healthy control group (n = 30), intensive care unit (ICU) control group (n = 62), septic nonshock group (n = 40), and septic shock group (n = 94). Serum levels of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), fission protein 1 (Fis1), mitofusin2 (Mfn2), and Parkin were measured by enzyme-linked immunosorbent assay at the time of enrollment for all groups. Clinical parameters and laboratory test results were also collected. Results: The levels of MQC-related biomarkers between any two of the four groups were significantly different (P < 0.001 for all). The serum levels of PGC-1α, Mfn2, and Parkin were lowest in healthy individuals; the levels were dramatically higher in the ICU control group compared with the others, and they decreased progressively from the septic nonshock group to the septic shock group. However, the pattern for Fis1 was inverse; the more severe the condition was, the higher the level of Fis1. Moreover, there was moderate correlation between MQC-related biomarkers and the SOFA score (PGC-1α, r = −0.662; Fis1, r = 0.609; Mfn2, r = −0.677; Parkin, r = 0.−0.674, P < 0.001 for all). Conclusions: The serum levels of PGC-1α, Fis1, Mfn2, and Parkin were significantly correlated with organ dysfunction and reflected the disease progression and severity. The dynamic surveillance of these four biomarkers could be beneficial to predict outcome and guide treatment.

The development of an n-type, graphene-based semiconductor is currently a significant research interest. Graphene is easily p-doped by adsorbates such as oxygen and moisture and thus a p-type semiconductor can be easily prepared. However, the development of an n-type semiconductor is required to fabricate a complementary circuit, and nitrogendoped (N-doped) materials would be useful in real device applications. Chemical doping is an important method used to modulate the electrical properties of graphene. Both theoretical calculations and detailed experiments have proved that chemical doping with foreign atoms, such as nitrogen, is an effective approach to achieve n-type semiconductors. [1] nType semiconductors can be obtained by replacing carbon atoms with nitrogen atoms in the graphene framework. The lone electron pairs of nitrogen atoms play an important role in producing a delocalized conjugated system with sp 2 hybridized carbon frameworks [2–4] that can enhance the reactivity and electrocatalytic properties of graphene. Substitutional N-doped multilayer graphene sheets were synthesized by adding NH3 gas during the chemical vapor deposition (CVD) growth of graphene, [1] and the monolayer growth of N-doped graphene sheets by using poly(methyl methacrylate) (PMMA) and pyridine was recently reported. [5, 6] The nitrogen-doping behavior of graphene and reduced graphene oxide (rGO) through electrical joule heating and thermal annealing in NH3, respectively, has been reported to produce an n-type semiconductor. [7, 8] However, the systematic investigation of graphene doping is required to achieve a large N-doping effect in real device applications. A high atomic percentage of dopant nitrogen is important in the fabrication of n-type rGO with a large shift of the Dirac point (DP). The catalyst-free synthesis of N-doped graphene by thermal annealing of graphene oxide (GO) with melamine through a bulk reaction was reported to provide a high atomic percentage of nitrogen on the rGO surface.

An evaluation at nursery stage of 56 wild accessions of 3 provenances of Amazon basin, Acre (AC), Rondonia (RO) and Mato Grosso (MT) of wild Hevea brasiliensis (Para Rubber) and 2 rubber commercial clones was carried out at the Regional Research Station of Rubber Research Institute of India located at Sukma , a drought prone area under dry sub humid region of Bastar district in centraleastern India to obtain information about potential of variability in quantitative traits .. Among the different accessions, girth ranged from 3.84 cm (AC 685) to 8.0 cm (RO 876), scion height 133.4 cm (AC 158) to 292.37 cm {RO 897), number of leaves 11.0 (AC 623) to 51.75 (RO 876) and leaf area from 85.49 cm' (MT 58) to 195.60 cm 2 (AC 623). The observations revealed wide inter and intra provenance variations for all the quantitative traits. The existence of high variability was evidenced by moderate to high estimates of phenotypic and genotypic coefficient of variation for the traits. High heritability was observed for girth and scion height. Among the three provenances, Rondonia exhibited superiority for most ofthe traits. Ajudicious selection ofthese promising diverse materials would be useful in future breeding programmes.
