Purulent arthritis of the sternoclavicular joint requires surgical treatment. The volume of the intervention depends on the degree of the joint's transformation and patient's general condition. The resulting defect of the chest wall tissues requires surgical closure at the reconstructive stage. In case of an extensive defect area with a skin deficiency, it is most advisable to use full-thickness flaps of the latissimus dorsi or pectoralis major muscles.
The article presents a clinical case of a patient operated for purulent arthritis of the sternoclavicular joint. The surgical treatment was planned in two stages. During the first stage, the use of vacuum-assisted dressings demonstrated its effectiveness. The second, reconstructive stage, included plastic surgery for the chest wall defect using a full-thickness flap of the pectoralis major on the thoracic branch of the thoracoacromial artery. The progress of the patient's surgical and general treatment was described in detail.

Physiological changes in 'Hakuho' peach [Prunus persica (L.) Hatsch] flower buds during endodormancy and ecodormancy were investigated based on their water status measured by differential scanning calorimetry (DSC) and nuclear magnetic resonance (NMR) spectroscopy. The developmental stage in ecodormancy, which was estimated as the number of days between the sampling date for shoots and the bloom date after forcing, was dominated by absorption of water and was closely related to the water content per dry weight. Two types of water differing in spin-lattice relaxation time (T1) of protons were detected in the flower buds. Water with the shorter T1 was considered to be freezing water as well as that with a longer T1. Nonfreezing water can not be detected by NMR. The change in the longer T1 coincided with the change in the water percentage relative to bud fresh weight and reflected the physiological development in ecodormancy. The shorter T1 value started to increase shortly before rest break and may have some relation with the physiological change at rest break. The buds of most deciduous trees show no visible growth soon after their formation in the autumn, even if the temperature is favorable for bloom (endodormancy). Endodormancy is broken by a certain amount of chilling temperature (Chandler and Tufts, 1934). The period following endodormancy and before bud break. when buds remain dormant because ambient temperatures are unfavorable for growth, is endodormancy. Information on the developmental stages of buds is useful in horticulture for estimating the flowering date in orchards and determining the time when heating should be started for greenhouse forcing. The progress in the developmental stage cannot be determined clearly from the appearance of buds. However, some cellular components change throughout endoand ecodormancy. For example, the abscisic acid (ABA) level. which has been studied in buds of several species. is highest at the time of leaf fall during endodormancy and decreases throughout ecodormancy (Corgun and Peyton. 1970: Harrison and Saunders. 1975: Mielkc and Dennis. 1975; Wright. 1975: Seeley and Powell. 1981). It has also been reported that sour cherry flower buds accumulate starch during endodormancy (Felker et al.. 1983), and desaturated membrane lipids in apple buds increase during endoand ecodormancy (Wang and Faust, 1990). Since water is the main solvent for these cellular components responsible for physiological development. changes in the mobility of the water in bud tissues are expected to accompany the physiological changes. We therefore investigated the water status of flower buds to detect the physiological changes occurring during development toward bud break. The water status of biological samples can be measured by means of nondestructive methods, such as nuclear magnetic resonance (NMR) spectroscopy. The NMR relaxation times of water protons reflect the motion of water molecules in tissues (MathurDe Vre. 1984). Several types of water with different relaxation times indicating differing molecular mobility are usually found in living samples. The water in different physical status is detected by differential scanning calorimetry (DSC) based on the melting or crystallization heat curve characteristics. Thus, we can identify water in living samples according to this property. In this research we investigated the water status of peach flower buds by NMR and DSC during endodormancy and ecodormancy. Materials and Methods Plant materials Ten first-year shoots, 30 to 40 cm in length. were randomly collected twice a month from 5 Dec. 1989 to 26 Mar. 1990 from 9-year-old 'Hakuho' peach trees planted at the Fruit Tree Rescearch Station in Tsukuba, Japan. Bloom date was 30 Mar. The temperature in the orchard was recorded with a platinum resistance thermometer placed ≈ 1.5 m above the ground. Proton relaxation time measurement. The collected shoots were divided into three sets at each sampling time to obtain replicates for relaxation time measurement. Flower buds were taken from the central part of each shoot and placed in a 10-mmdiameter NMR sample-tube. Twenty five buds were used per replicate until early February. Because of the increase in bud J. AMER. SOC. HORT. SCI. 120(2): 134–138. 1995. Fig. 3. Changes in water content ( ■ ) and water percentage as to fresh weight of a peach flower bud ( ❏ ). Fig. 1. Changes in moving average of the previous five days temperature (-----), the percentage of bloom after forcing ( ■ ) and the number of days between sampling and bloom date ( ❏ ). Sample shoots were forced at 20C. The percentage of bloom was calculated 50 days after forcing and bloom date was defined as the date on which 30% of the shoots had bloomed. Fig. 2. Changes in fresh weight ( ■ ) and dry weight ( ❏ ) of a peach flower bud volume, only 20 were used in late February, 15 in early March, and 3 in late March. The spin-lattice relaxation time (T1) of water protons in the flower buds was measured with a NMR spectrometer (FX-90Q; JEOL, Tokyo) by the inversion recovery (IR) method. With a 4500-Hz spectral width and a 3to 5-sec pulse repetition time according to the T1, free induction decay (FID) was accumulated four times at 27C, and 20 date points with different pulse intervals were collected for each sample for T1 calculation. The measurement time for a sample was ≈ 10 min. The number of water components with a different T1, the population of each water component, and each T1 were determined from the resultant relaxation curve by a nonlinear least squares method using a subroutine of simplex written by Kobayashi (1981) on a computer (Yoshida and Nose, 1987). Measurement of dry weight and freezable and nonfreezable water contents. Flower buds used for the determination of T1 were weighed and dried at 80C for 2 weeks. Their water content was calculated as the difference between fresh and dry weight. The amount of freezable water in buds was measured once or twice monthly by DSC analysis according to the method of Hatakeyama et al. (1988). A bud was placed in a DSC cell, which was then sealed and weighed. The cell was then placed in a DSC 100 calorimeter (Seiko, Tokyo) linked with a SSC5000TA station. The instrument was calibrated using the heat of pure ice melting, 333 J/g. The sample was frozen at –150C at a cooling rate of 5C/ min and then the temperature was raised at the rate of SC/min until it reached 60C. The peak area of the thermograms was measured by assuming a linear base line between temperatures prior to and after melting. The amount of freezable water was calculated from the area by using a calibration constant. The bud was then pre-dried at 100C and dried under vacuum at 115C for 2h. The decrease in weight after drying was taken as the loss of total water. The unfrozen water content was obtained as the difference between the total water content and the freezable water content. Estimation of the developmental stage. The shoots, from which some of the flower buds were taken for the T1 and DSC measurements, were put in a pail of water in a dark room at 20 ± 0.5C and the humidity maintained at 80% ± 10%. The number of shoots in bloom was determined every day. A shoot was considered to have bloomed when at least one of its buds had flowered. The bloom date was defined as the date on which 30% of the shoots had bloomed. The percentage of bloom was calculated as (the number of shoots in bloom after 50 days' forcing/the number of all forced shoots) x 100.


Standard electrochemical techniques were used to investigate the interaction of oxygen with both smooth and platinized platinum in aqueous solution. The formation of oxide films on the metal surface follows Elovich kinetics and this is explained in terms of increasing inhibition of the chemisorption of oxygen molecules at the interface by electrostatically-adsorbed water molecules. This type of effect, which is well known from the behaviour of organic compounds in double layer studies, is used to account for the failure of the conventional oxygen electrode to attain its reversible potential value. The theory also accounts for literature reports of departures from simple Nernstian and Tafel behaviour of this electrode system.


Streptomycin sulphate prevented infection of sunflower seedlings by three races of the downy mildew pathogen Plasmopara halstedii (Farl.) Berlese et de Toni. It inhibited emergence of zoospores from zoosporangia and at high concentrations (500 ppm) was phytotoxic. Affected seedlings were stunted and chlorotic. Penicillin had no observable effect on infection or on appearance of the seedlings.


AbstractThis study demonstrates that personal names present an excellent opportunity for symbolic interaction sociologists to engage in research devoted to determining the nature and structure of their key variable, meaning. Using the technique of multidimensional scaling, ten men's names are mapped in 3- and 4 dimensional space. The four dimensions are identified as Character, Maturity, Sociability and Virility. The three dimensions are identified as Activity, Evaluation and Potency combined with Age. Both solutions are acceptable using standard criteria. Nicknames are shown to be a composite of the other dimen.sions, rather than a separate dimension.

False data detection, intrusion detection and coverage rate are major challenges in wireless sensor networks (WSN). Scheduling in media access control (MAC) using gateway and relay nodes solve some of the problems. In this paper, we carried out a brief survey on scheduling, delay aware MAC, cooperative communications in MAC, and adaptive listening to keep controlling the energy in sensors. In addition, multichannel MAC and various routing strategy techniques for WSN are discussed. Firefly algorithm for dynamic scheduling pipelined scheduling for linear sensor networks gives better throughput and latency. Heuristic configuration solves the overhearing problem, as node power-based MAC controls power of each node. Based on WSN applications and the performance metrics concentrated, various techniques for MAC are discussed throughout in this paper.

Introduction Various stem cell-based therapies have been proposed as supportive treatments for patients following solid organ and vascularized composite allotransplantation (VCA) to achieve donor-specific tolerance and eliminate the toxic, systemic, life-long, multi-drug immunosuppression. We introduce a novel cellular therapy of ex vivo created umbilical cord blood derived multi-chimeric cells (mCC) as an alternative approach to bone marrow based therapies in support of VCA. The aim of this study was to establish the ex vivo fusion protocol and characterize in vitro the phenotype, genotype, viability and proliferative potential of fused human mCC. Methods Twenty ex vivo fusions of human umbilical cord blood (UCB) cells were performed. Mononuclear cells (MNC) were isolated from UCB originating from three unrelated donors. Next, MNC were stained separately by PKH26, PKH67 and eFluor670 proliferation dye and fused using polyethylene glycol (PEG). Triple PKH26/PKH67/eFluor670 stained mCC were sorted and assessed by confocal microscopy and flow cytometry for the efficacy of the cell fusion procedure. The viability of mCC (Trypan blue and LIVE/DEAD cell viability assay) and distribution of hematopoietic surface markers (CD4, CD8, CD19, CD45 and CD90) were performed by flow cytometry. PCR-rSSOP (Antigens: A, B, C, Bw, DRB1, DQB1, DR51, DR52 and DR53), and STR-PCR (Loci: TH01, D21S11, D5S818, D13S317, D7S820, D16S539, vWA, TPOX) characterized the genotype of mCC. Proliferative potential of mCC was assessed by colony forming unit (CFU) assay. Results Flow cytometry and confocal microscopy analysis confirmed UCB fusion and creation of human mCC. Using PCR-rSSOP and STR-PCR assays, we determined that human mCC are sharing HLA class I and class II antigens, as well as selected loci specific for all three UCB donors used for fusion. After fusion 90-95% of cells were viable. Phenotype characterization showed similar percentage and pattern of hematopoietic markers distribution on the surface of mCC and UCB donors. Maintenance of proliferative properties of mCC was confirmed by CFU assay. Conclusions We have successfully confirmed the feasibility of ex vivo fusion procedure and creation of human mCC. We characterized the phenotype, genotype, viability and proliferative potential of mCC. This unique concept of mCC introduces a novel universal therapy for tolerance induction in solid organ and VCA transplantation. DOD AFIRM W81XWH-13-2-0053.


Management Information Systems (MIS) have been widely used in the construction industry for a number of Information Communication and Technology (ICT) systems ranging from payroll to machine inventory applications. However, in recent years MIS has also been utilised by occupational health and safety advisors, specifically, when dealing with plant and equipment operations. Anecdotal evidence would suggest that the high (and largely unchanged) incidence of plant and equipment accident rates coupled with the growing number of new legislative requirements have been instrumental factors driving this change agenda. This uncontrolled change of MIS utilisation has lead to an explosion of bespoke system applications being developed and often these focus on single applications such as machine maintenance, vehicle tracking or continuous mechanical health monitoring. At present there is no single holistic package that covers the whole scope of machine related activities that could benefit health and safety. This paper presents some of the first research to produce a critical appraisal of existing MIS systems applied to the safe management of mobile plant and equipment on construction sites. Leading on from this, the work then proposes a new system that encapsulates the desirable attributes of various systems into one integral hybrid system.

The Munich example demonstrates the architectural and cultural approach to the analysis of the large cities' planning structure. In the context of the urban planning fabric's historical development, the main planning axes are singled out and a conceptual model of mega ensembles is built. Particular attention is paid to the city's hydrography, the main components of which are the Isar River, the Nymphenburg canals and the Northern system of the Munich canals, which began to be formed in the 17th century and had finally been developed by the beginning of the 20th century. Munich's northwest quadrant, formed much earlier than the other three, was chosen as the main object of study, on the territory of which the urban triptych was identified as the main system-forming mega-ensemble, formed, firstly, by the city's historical center with two other triptych elements emanating from it Brynner Strasse and Ludwig Strasse, respectively, secondly, the Olympic Park and thirdly, the Nymphenburg Palace and Park complex, connected with the second element of the triptych by the Nymphenburg-Biedersteiner Canal.


Abstract. We develop a convergence theory for noise level-free paramet er choice rules for Tikhonov regularization of finite-dimensional, linear, ill-conditioned problems. In particular, we derive convergence rates with bounds that do not depend on troublesome parameters such as the small singular values of the system matrix. The convergence analysis is based on specific qualitative assump tions on the noise, the noise conditions, and on certain regularity conditions. Furthermore, we derive several suffi cient noise conditions both in the discrete and infinitedimensional cases. This leads to important conclusions for th e actual implementation of such rules in practice. For instance, we show that for the case of random noise, the regul arization parameter can be found by minimizing a parameter choice functional over a subinterval of the spectr um (whose size depends on the smoothing properties of the forward operator), yielding discretization independe nt convergence rate estimates, which are of optimal order under regularity assumptions for the exact solution.

The present study was aimed to screen 19 elite genotypes and three check strains of chickpea for genotype x environment interaction (G x E) at four locations with varying micro and macro climatic conditions for yield associated phenotypic characters. The Randomized Complete Block Design (RCBD) with four replications was selected to conduct experiment. The means were used to compute pooled analysis of variance followed by regression analysis to measure G x E. The regression analysis revealed significant genotype x environment interaction for all the phenotypic characters. The mean values of crude protein (%) and 100-seed weight were highly significant for linear as well as non linear component of G x E, whereas for number of seeds per pod only non linear component was highly significant (p <0-05, p<0-01). The studied genotypes exhibited varying adaptability at different environments. Protein content, 100-seed weights were the highly sensitive trails for environmental stress. Genotypes 90280 and 94014 were stable genotype over wide range of environments are promising candidate Chickpea varieties.


This research was conducted to determine the effects of organic and inorganic fertilizer treatments (F1, F2, and F3) on some growth parameters of hybrid corn cultivars (C1, C2, and C3) in the years 2011 and 2012 under the ecological conditions of Eskipazar, Karabuk. In both study years, fertilizer treatments were statistically significant on plant height, leaf area, and fresh plant weight. The highest values were obtained from F2 and F3 fertilizer treatments. Fertilizer treatments were statistically significant on fresh leaf and stem ratios in the first year but in the second research year no statistical differences were found. In both study years, the corn cultivars were statistically significant on the plant height, number of leaves, leaf area, fresh leaf, ear and stem ratios. While the cultivars were statistically significant on dry matter in the first research year, they were statistically significant on stem diameter and fresh plant weight in the second research year. In both study years the highest plant height, number of leaves and fresh stem ratio values were obtained from C2 cultivar. The largest leaf area and fresh leaf ratio values were obtained from C3 and C1 cultivars and the highest fresh ear ratio values were obtained from C3 cultivar. Fertilizer treatment x cultivar interactions were statistically significant on fresh plant weight in the first study year while they were significant on the number of leaves, and fresh leaf ratio in the second study year. In the first study year, the highest fresh plant weight values were obtained from F2 x C3, F2 x C2, F3 x C3, and F3 x C1 interactions. In the second study year, the highest number of leaves were obtained from F3 x C2 and F1 x C2 interactions. In the second study year, the highest fresh leaf ratio was obtained from F2 x C1 interaction. As a result of the study, the highest values of growth parameters were obtained from F2 and F3 fertilizer treatments in all three corn cultivars (C1, C2, and C3). When we consider the sums paid for the export of inorganic fertilizers and the negative effects of these inorganic fertilizers on human and environmental health, we may see that F3 fertilizer applications would be preferable in the regions where corn is grown.

In this paper, a novel approach for establishing the route for process intensification through the application of two developed softwares to characterize reactive mixtures is presented. A robust algorithm was developed to build up reactive phase diagrams and to predict the existence and the location of reactive azeotropes. The proposed algorithm does not depend on initial estimates and is able to compute all reactive azeotropes present in the mixture. It also allows verifying if there are no azeotropes, which are the major troubles in this kind of programming. An additional software was developed in order to calculate reactive residue curve maps. Results obtained with the developed program were compared with the published in the literature for several mixtures, showing the efficiency and robustness of the developed softwares.


The embroidered subject "Cujin" was frequently mentioned in the poems of the Tang and Five Dynasties. Five embroidered pieces of clothes made with the skill of "Cujin" have been unearthed from the underground palace of Famen Temple; they are the real proof of this object and lend support to the notion in poems. At the same time, they reveal a degree of Buddhist significance. The "Cujin" is a kind of embroidery craft which uses tightly twisted gold threads to make wrinkled fabric. This kind of embroidery shows the most intensive texture and the most beautiful body. It was very popular among the royals and some nobles in the Tang Dynasty and was often used for daily use or decoration. So poets like to use "Cujin" in their poems to show the living situations of the aristocratic society. Based on its superiority, "Cujin" makes a big difference in representation in poems when compared to "Panjin", "Lujin" and "Tiejin". It can be concluded that this special object in poems has a rich cultural connotation.


To define the nature of procuratorial power as the legal supervision rights has become the main idea of academic circles.But there are still some misunderstandings on legal supervision in the academic circles and judicial practical circles,so more explanations are needed on it.Our national constitution has defined the procuratorial organs as the legal surveillance institution.The constitutional qualification of procuratorial power is closely related to the constitutional characterization of the procuratorial organs,but they are not the same.To solve the problem of the procuratorial organs' constitutional position,the relationship between procuratorial power and trial power must be well dealt with.The trial supervision should strenghthend which include the supervision related to the lawsuit and the supervision related not to the lawsuit.Because there are contradictions and conflicts between the two main principles of trial independence and procuratorial supervision,so the way to harmonize their relationship is not only to maintain the trial independence and its authority but also to keep the procuratorial supervision's legalization and efficiency.


A ligninsulphonate preparation purified by extration with butanol as dicyclohexylamine salt of ligninsulphonate from sulphite spent liquor, has been reprecipitated as a barium salt from aqueous solution by ethanol to yield a large number of fractions which has been characterized by molecular weight, sulphonate group content and viscosity in sodium chloride.It has been found that the molecular weights of ligninsulphonates range from a few hundred to about one hundred thousand and that sulphonate group content changes with increase in the molecular weight. In fractions of lower molecular weight, the presence of individual ligninsulphonate has been supposed by relation of the molecular weights and the sulphonic equivalent weights.The relationship between molecular weights and intrinsic viscosities in sodium chloride, has been explained by considering that ligninsulphonate molecules exist in solution as non-rigid and branched-chain polymers which are solvated and randomly coiled. From the variation of the constant a (in [η] =K·Ma) with molecular weight, it may be concluded that the degree of molecular branching of the high molecular weight ligninsulphonates is greater than that of low molecular weight fractions, and that ligninsulphonates of molecular weights less than about 5, 000 have linear or less branched-chain molecular structures.


tivity. It may be difficult for educators to convince employers of the benefits of promoting critical thinking and problem posing in their employees, who may use their new skills to advocate for change. The book lacks practical advice for selling the concept of learner-centered education to the employers. Without the cooperation of the organization, the workplace educator will find it very difficult to implement the practical suggestions that are the major contribution of this book.


Life safety applications are being developed and creating a new era of creativity and these applications are more sophisticated to use and user friendly which also makes machines to think and make own decisions. Accident is a specific, unpredicted external action that happens unexpectedly with no apparent or deliberate causes. With the increasing number of bike riders and also the number of accidents happening each year our paper focuses on the methods that can be implemented to ensure safety while driving. Violation of traffic rules and sudden brake's are the major cause of these accidents. Even though helmets are made mandatory accidents are happening everywhere due to over speed which leads to skidding. In our project, message transmitting sensors are equipped with the controller of bike. The most important feature of the bike is that it detects the distance of the successive vehicle and if the rider reaches the minimum distance to successive vehicle, it maintains a constant speed by controlling the fuel flow in the bike. This is applicable when traveling at top gears. This advanced development is bringing about a new era of productivity for the latest ideas on an astounding scale, understanding their efficiency, speed and functionality.


The newly freed slave obviously had great adjustments to make to his new status. The transition from a life of dependency to one of independent responsibility required some assistance, and the rendering of such aid fell to the Freedmen's Bureau,1 created March 3, 1865, and to benevolent societies. One of the many benevolent organizations intimately involved with the Negro during this critical period was the American Missionary Association.

The total syntheses of three closely related cyclic peptide natural products, cyclocitropsides A-C, are described. Cyclocitropside A could be readily converted into cyclocitropsides B and C through an asparagine deamidation pathway, indicating that this is a plausible biosynthetic route to these compounds.


Objective: To contribute to the construction of parameters of biosafety in order to protect government agents in the exercise of their investigative functions in the context of a pandemic, as well as to resolve clinical, pathological and possibly legal issues. Methodology: The development of an exploratory review study with a qualitative approach was defined. The methodological design was carried out on the platforms: PubMed and SciELO through the descriptors: Human identification, Radiology, Virtópsia and Autopsy. The exclusion criteria include articles with duplicate information or that do not have information related to the objectives of the study. For inclusion, materials published in Portuguese, English or Spanish were used and at the end 76 articles were obtained. Results and discussion: Conventional autopsy is the most common method for post-mortem investigation in humans. However, with the evolution of imaging methods and the current pandemic threatening the health of government agents, Virtópsia has shown itself to be the most promising way to remedy the dichotomy of occupational risk and legal benefit. Final considerations: In this article, the main advances in Forensic Radiology in the last 11 years were described, with regard to the use of ante and post mortem radiographs in the identification process. Among the various radiological techniques treated, the following stand out: radiographic techniques produced by radiology professionals with different assessments in the radiological area. The images produced are security methods with invasive manipulation and use of all PPE, suitable for the pandemic moment.


Surface integral equation models for electromagnetic wave scattering by dielectric cylinders are well known. The most common of these involve distributions of electric and magnetic surface current constrained by a pair of coupled integral equations. Less well known, but of great practical interest, are integral equations that have been developed for the solution of this same problem in terms of a single unknown current distribution. An excellent summary can be found in [ 1]. The first of these so called single integral equations had represented the scattered field only in terms of an electric current distribution, and had consequently suffered from non-uniqueness at frequencies corresponding to eigenvalues of the· associated interior problems. More recently, single integral equations with unique solution at all frequencies have been proposed, but numerical results had not been presented [ 1]-[3]. Unique solution of a single integral equation is achieved by representing the scattered field in terms of a combined electric and magnetic current distribution having a fixed ratio.


The US Supreme Court, in a decision written by Chief Justice William H. Rehnquist, ruled that the Clean Water Act (CWA) does not authorize the federal government to regulate the dredging and filling of isolated ponds and wetlands.


A set of 21 male sterile based F1 hybrids developed as a result of line × tester mating design involving three cytoplasmic genic male sterile (CGMS) lines and seven testers were evaluated for growth (stem girth, plant height, plant spread, number of secondary and tertiary branches), earliness (days to first and 50 per cent flowering) and early green fruit yield. Out of these crosses, L3 × T16 was found best for stem girth, plant spread and number of tertiary branches, L3 × T15 for plant height, L1 × T16 for number of secondary branches, L1 × T14 for days to first and 50 per cent flowering and L5 × T14 for early green fruit yield. The data on the magnitude of heterosis revealed that these best crosses also expressed the maximum economic heterosis over both the check hybrids in desirable direction for their respective traits. The cross L5 × T14 was most heterotic over both the check hybrids for early green fruit yield followed by L3 × T14.


We introduce two online gradient-based reinforcement learning algorithms with function approximation – one model based, and the other model free – for which we provide a regret analysis. Our regret analysis has the benefit that, unlike many other gradient based algorithm analyses for reinforcement learning with function approximation, it makes no probabilistic assumptions meaning that we need not assume a fixed behavior policy.


Major hepatectomy with concomitant pancreatoduodenectomy (major‐HPD) is the only procedure that provides a curative resection for diffusely spread extrahepatic bile duct cancer (DSEBDC). We sometimes encounter patients who cannot undergo major‐HPD because of a poor functional hepatic reserve. The aim of the present study was to assess the feasibility of central hepatectomy with pancreatoduodenectomy (central‐HPD) for patients with DSEBDC as an alternative to major‐HPD.


To plan a suitable organizational growth as well as for great contribution for the economy, ECX need to identify the basic problems.Hence, the purpose of this study is to examine the basic challenges of ECX on coffee: with the reference of yirgachiffe, sidama, harari and jimma coffee.The findings result from this study reveal that shortfall of agricultural product, physical infrastructure, macroeconomic instability, price fluctuation, lack of adequate warehouses that accommodate ECX participants request,. Higher penalty cost imposed on the participants for not withdrawing their commodity from the warehouses, poor quality of warehouse service insufficient time to store and transfer the commodity, inefficient and inadequate in store credit; discouraging the membership requirement of ECX, expensive membership seat fee and exposed for corruption were found to be amongst the fore front challenges to the success of ECX.


An open issue in adaptive infinite-impulse response (IIR) filtering is that of convergence to a global minimum in the presence of observation noise when the system is insufficiently modeled . It is well known , that algorithms based on equation error (EE) formulation contain a single minimum that may be biased whereas, algorithms based on output error (OE) ensure the existence of an unbiased global minimum in presence of local minima. Recently, there have been several attempts to combine these formulations in order to ensure the existence and uniqueness of an unbiased minimum. Works presented here, EEOE and modified EEOE (MEEOE), are such attempts in the context of system identification. We will show, analytically and through simulations, the convergence properties of the MEEOE approach, in the context of system identification.


A field study was conducted at Ladhowal, Ludhiana during 2004–05, 2005–06 and 2006–07 to evaluate alternate herbicides for control of atrazine tolerant Brachiaria reptans in spring sugarcane. Pre-emergence atrazine 1.0 kg (standard), metribuzin 1.4 kg, diuron 1.6 kg and pendimethalin 1.125 kg/ha alone, tank mix of pendimethalin 0.75 kg with atrazine 0.75 and 1.0 kg, metribuzin 0.875 and 1.4 kg and diuron 1.6 kg/ha, three hand hoeings at 30, 60 and 90 days and unweeded control were evaluated in RBD. Atrazine 1.0 kg/ha recorded Brachiaria population and cane yield similar to unweeded control. Metribuzin 1.4 kg and diuron 1.6 kg/ha alone, tank mixing of pendimethalin 0.75 kg with metribuzin 0.875 kg or atrazine 1.0 kg/ha reduced Brachiaria population by 82 to 96% and increased cane yield by 16 to 28% than alone atrazine 1.0 kg/ha. Weed control efficacy under above treatments varied from 67 to 72%, while it was only 12% with atrazine 1.0 kg/ha. Pendimethalin 1.125 kg/ha though reduced Brachiaria density by 89%; however, its lower activity over time resulted in poor weed control efficacy (45%) and similar cane yield to atrazine 1.0 kg/ha. Metribuzin 0.875 kg+pendimethalin 0.75 kg/ha recorded the highest cane yield (76 t/ha), net returns (Rs 48,200/ha) and benefit: cost ratio (0.840). Different weed control treatments did not influence cane quality. Metribuzin 1.4 kg and diuron 1.6 kg/ha alone, and tank mix of pendimethalin 0.75 kg either with metribuzin 0.875 kg or atrazine 0.75 kg/ha were very effective for control of B. reptans and attaining the highest productivity and profitability in spring sugarcane.

In this letter we show that a set of users with specified target signal-to-interference+noise-ratios (SINRs) are admissible in the uplink of a multicode CDMA system with multipath if and only if the sum of their effective bandwidths weighted by their corresponding number of codewords is less than the dimension of the signal space in which the users operate.


In developing enterprise solution, integration of inter-enterprise and intra-enterprise applications is a great challenge. Traditional approach of enterprise application integration (EAI) has drawbacks of: (i) scalability (ii) portability (iii) interoperability (iv) vendor dependency and (v) dynamic nature of application. Web service based enterprise application development and integration approach resolves these issues. In addition, it also reduces cost, efforts and time in comparison of other middleware technologies like RMI, CORBA, etc…. This paper presents the internals of Web services execution and involved components running on heterogeneous platforms. We present Web service based integration algorithm for integrating different subsystems. We identified university rechecking/reassessment procedure at our university as an application facing problems of integrating two subsystems existing on diverse platforms. For validation of our algorithm, we have demonstrated the implementation of this procedure using Web service based development and integration approach. The work presented in the paper would help in designing, implementing and integrating solutions for enterprise applications.


A highly efficient protocol for the synthesis ofN-substituted di-/tetrahydroisoindole derivatives and N-substituted pyrroles fused with seven-membered rings has been developed by reaction of amines with 3-(2-formyl-cycloalkenyl) α,β-unsaturated esters or nitriles, which, in turn, were prepared from β-bromovinyl aldehydes by a Pd(0)-catalyzed Heck reaction. Bisisoindoles were also achieved by this room-temperature procedure.


Fabricating cementitious composites with sustainable materials represents an essential aspect in the recent developments in the construction section. On the other hand, using fibers within the binding matrix to enhance its strength properties is a familiar application and holds significant importance to the research community. In this investigation, the Geopolymer matrix which is based on silica fume (micro silica) and blast furnace slag (GGBS) was reinforced with five different fiber types to form slurry fiber reinforced concrete (SIFCON). Hook-ended steel, crimped steel, elastoplastic, macro twisted, and macro nylon fibers were used, the results revealed the fact that steel-based specimens generally yielded better results when compared to specimens reinforced with other fiber types. Normal condition results of hook-ended and crimped fiber-based specimens yielded an increment of more than 10% in both compressive and flexural strength tests while their elevated temperature results showed strength loss rates less than specimens with other fiber types. Also, with acceptable performance in both conditions, macro twisted fibers can be considered as potential fibers for geopolymer based SIFCON.

Abstract Objective The present study investigated the impact of hearing impairment on the implementation of proactive and reactive cognitive control strategies across the ageing process. Methods 31 hearing-impaired (HI) individuals with one cochlear implant and 41 normal-hearing (NH) listeners of different ages performed the AX–CPT, a well-validated task to measure proactive and reactive cognitive control strategies. Data from both accuracy and response times (RTs) were analysed by mixed effect models that considered trial type, group, age and their interactions. Results Both accuracy and RT analyses showed significant interactions between trial type, group and age. Specifically, with ageing, the NH group had lower performance on AY and BX trials (i.e. the most conflicting trial types of the AX–CPT associated with proactive and reactive control). Conversely, HI participants yielded higher performance on the same trial types at older ages. However, for the HI group only, the accuracy benefits observed for AY and BX trials were coupled with an age-related RT increase on both trial types (i.e. speed accuracy trade-off). Conclusion The present findings show a different utilisation of cognitive control strategies in HI participants as compared to NH listeners, at both younger and older ages.


This article explores the available research literature on language development and language interventions among deaf and hard of hearing (d/hh) children. This literature is divided into two broad categories: Research on natural languages (specifically American Sign Language and spoken English) and research on communication systems (specifically iterations of signed English and cued speech). These bodies of literature are summarized, with special attention paid to intervention research and research exploring the impacts of language skills on literacy development. Findings indicate that there is generally a stronger research base on natural languages as compared to communication systems, though more studies in both categories are necessary. Additionally, there are very few intervention studies and even fewer that aim to intervene upon language with the explicit goal of impacting literacy; therefore, there is little known about whether and how interventions that aim to support language development may have direct or indirect impacts on literacy within this population. Further research on this topic, as well as replication studies and research with larger sample sizes, is strongly recommended.

The shape of two-dimensional materials plays a significant role on their chemical and physical properties. Two-dimensional materials are basic meshes that are formed by mesh points (vertices) given by atomic positions, and connecting lines (edges) between points given by chemical bonds. Therefore the study of local shape and geometry of two-dimensional materials is a fundamental prerequisite to investigate physical and chemical properties. Hereby the use of discrete geometry to discuss the shape of two-dimensional materials is initiated. The local geometry of a surface embodied in 3D space is determined using four invariant numbers from the metric and curvature tensors which indicates how much the surface is stretched and curved under a deformation as compared to a reference pre-deformed conformation. Many different disciplines advance theories on conformal two-dimensional materials by relying on continuum mechanics and fitting continuum surfaces to the shape of conformal twodimensional materials. However two-dimensional materials are inherently discrete. The continuum models are only applicable when the size of two-dimensional materials is significantly large and the deformation is less than a few percent. In this research, the knowledge of discrete differential geometry was used to tell the local shape of conformal two-dimensional materials. Three kind of two-dimensional materials are discussed: 1) one atom thickness structures such as graphene and hexagonal boron nitride; 2) high and low buckled 2D meshes like stanene, leadene, aluminum phosphate; and, 3) multi layer 2D materials such as Bi2Se3 and WSe2. The lattice structures of these materials were created by designing a mechanical model the mechanical model was devised in the form of a Gaussian bump and density-functional theory was used to inform the local height; and, the local geometries are also discussed.


It is no crank. The script was written by a highly respected physician for a patient undergoing cancer chemotherapy, a patient who has found that if he smokes a joint just before treatment he is relieved of much of the nausea and vomiting that has become part of his ordeal. This scenario invites provocative questions. Is the writing of this script legal even though acquisition of the drug is not? What happens if the patient is picked up for possession by the police and flashes the prescription? Could the physician be charged as an accessory since he knows the filling of the script is an illegal act? "If the government gets on to this it will make an interesting case," says Dr. Lionel Solursh, psychiatrist at the Toronto Western Hospital and head of CMA's subcommittee on nonmedical use of drugs. (Dr. Solursh is not the physician who wrote the prescription.) "Whether that prescription permits him to be in possession of up to an ounce since he can't legally fill it is a question mark. We don't know the answer," says Solursh. But he adds that in a recent private conversation, a well-known provincial judge admitted that if presented with the scenario in his courtroom he would dismiss the case. So far the argument is hypothetical. But if the current wave of therapeutic claims for not only manhuana but heroin continues, it is just a matter of time before the scenario is playe.I out in earnest. During the past three decades marihuana and heroin have been dis-


SUMMARY This research examines the impacts of consumer's two crossnational individual difference variables-country-of-origin perception and consumer ethnocentrism-on their responses and attitudes toward foreign advertisements. Empirical analysis of the hypothetical model through structural equation modeling yields supportive results: negative effects of consumer's ethnocentrism on their responses to the creative presentation of international advertising, and positive effects of consumer's country-of-origin perceptions on their responses to the buying proposal of international advertising. This study may contribute to our understanding of cross-national individual difference variables that precede and determine consumers' attitudes toward international advertising. It also has practical implications for the standardization versus localization debate in international advertising strategy.


Harmonic analysis was used to detect the presence of a 12 months' cycle and a long term cycle in the arrival and price series of jowar markets in India. Trigonometric functions were used to discover the periodicities present in the price and arrival series of jowar in the Gadag and Hubli markets. Monthly modal data on price and arrivals for the period 1970 to 1978 (Hubli) and 1956 to 1978 (Gadag) were subjected to time series analysis. The Gadag and Hubli markets were found to require 17 and 11 days respectively for adjusting to price variations. Time lag reflects the imperfections in the market conditions


Blockchain technology constitutes a paradigm shift in the way we conceive distributed architectures. A Blockchain system lets us build platforms where data are immutable and tamper-proof, with some constraints on the throughput and the amount of memory required to store the ledger. This paper aims to solve the issue of memory and performance requirements developing a multiple Blockchain architecture that mixes the benefits deriving from a public and a private Blockchain. This kind of approach enables small sensors - with memory and performance constraints - to join the network without worrying about the amount of data to store. The development is proposed following a context-aware approach, to make the architecture scalable and easy to use in different scenarios.


Women have never been absent from the story, although the official historiography has overlooked. Researchers (s) has been working on studies of the history of women in agrarian societies and their struggles in all civilizing processes. Moreover, rural women have secured their place in life as a citizen in the world and in history itself. Throughout history there is a relationship between gender and power that needs to be studied, developed, rewritten, because the traditional anthropocentric and universalizing history created the myth of the weaker sex, impotence female and male existential dependence. This article analyzes the functions and roles established by history to rural women and the processes of reproduction and socio-cultural transformation by which they are passing, leading us to affirm that human identities are constructed through life, the meanings that groups social feeding in their cultural contexts.


Web tools for statistical investigation with an interactive and friendly interface enable users without programming knowledge to conduct their analyses. We develop an Interactive Correlation Environment (ICE) in an open access platform to perform spectral collinearity analysis for biogeochemical activity retrieval. We evaluate its performance on different browsers and applied it to retrieve chlorophyll-a (chl-a) concentration in a tropical reservoir. The use of ICE to retrieve water chl-a concentration got a Root Mean Square Error (RMSE) lower than 7% for seasonal datasets, enhancing ICE's ability to adapt it within season. An RMSE of 17% was found for the mixed dataset with a large range of chl-a concentrations. We conclude that the use of ICE is recommended, due to its quick response, easily manipulation, high accuracy, and empirical adaptation to seasonal variability. Its use is enhanced by the development of hyperspectral sensors, which allow the identification of several biogeochemical components, such as chl-a, phycocyanin (PC), soil salinity, soil types, leaf nitrogen, and leaf chl-a concentration.


Background:The US Preventive Services Task Force recommended against prostate-specific antigen (PSA) screening for prostate cancer based primarily on 2 large long-term randomized-controlled trials (RCTs) and a systematic review of harms resulting from screening. Objective:To support use of large, long-term randomized trials as the evidence base for clinical guidelines on screening and to draw attention to limitations of modeling studies used for this purpose. Methods:We respond to critiques of use of RCTs as the primary evidence base, considering the results of the Prostate, Lung, Colorectal and Ovarian (PLCO) and European Randomized Study of Screening for Prostate Cancer (ERSPC) trials, documented harms resulting from PSA screening, and methodological concerns with modeling studies. Results:The PLCO and ERSPC provided 11–13 years of follow-up on over 250,000 subjects. The PLCO, despite limitations, is most representative of US populations, screening and treatment practices, and showed no mortality benefit resulting from annual PSA testing after 13 years of follow-up. The confidence interval was narrow and precluded more than a 13% relative mortality reduction. Competing causes of mortality in older men make it progressively less likely that longer follow-up will demonstrate a large absolute reduction in disease-specific mortality. With continued screening, the increasing prevalence of asymptomatic cancers in older men will increase the rate of overdiagnosis. Potential harms from screening and treatment are significant. Conclusions:Projections from models are subject to mistaken assumptions and investigator biases, and should not be accorded the same weight as evidence from RCTs. Current empiric evidence is sufficient to support the US Preventive Services Task Force guideline that clinicians should recommend against PSA screening for prostate cancer.

In contrast, the human auditory system is not able to distinguish between two realizations of noise, provided that the temporal and spectral envelopes of both noises are the same. That means, an identification of the spectrotemporal envelopes of those noisy audio signals will allow a substitution with other noise without any perceptual change. Such an inaudible noise substitution will then enable a coding technique that only encodes the parameters of the spectro-temporal envelope and not the noisy signal part itself.

(ProQuest: ... denotes formulae omitted.)IntroductionResearch and development (RD Lev and Sougiannis, 1996) as well as their performance (Ho et.al.2006; Chambers et. al.2002.) RD Peteraf 1993, Wernerfelt 1984). Following resource based theory of firm it may be stated that companies allocating larger resources to R & D activity have greater inward strategic orientation. They create greater potential for generating higher future returns for they commit long term resources in areas where they have or likely to have core competence and opportunities for competitive advantage.ObjectivesThe primary objective of the present study is to examine relationship between R & D activity and stock market returns using Indian data thereby testing the universality of resource based theory of firm and also to discover the directionality of the flow of causality between the two variables.HypothesesA number of studies have examined the relationship between R & D expenditure and stock market returns. The evidence establishes existence of positive relationship between the two (Chan K. C. et.al 2001; Chan S. H. et.al. 1990; Lev and Sougiannis 1996; Sundaram et.al.1996; Connolly and Herschey, 1984). Also there is strong evidence to show that R & D intensity influences growth opportunities (Ho et. al 2006). Since these studies have employed US data, we shall explore whether such relationship exists in India or not. Being an emerging economy, its long term growth is contingent upon innovations at product and process level for ob vio us re a s on s . Accordingly, ou r f i rst hypothesis is :Hypothesis 1 : There exists significant positive relationship between R & D expenditure and risk adjusted market returns.Secondly, axiomatically it may be stated that R & D expenditure intensity increases risk of the firm because results of R & D efforts are not certain and hence possibility of exponential returns . Therefore, it is likely to introduce non-linearity in returns. In fact study by Ho et.al (2005) points towards presence of such non linearity. This leads to the second hypothesis :Hypothesis 2 : The relationship between R & D expenditure and risk adjusted returns in non linear.Thirdly, the studies examining relationship between R & D investment and stock returns have studied different aspects of the phenomenon such as: impact of accounting treatment of R & D expenditure on value (Lev et al. 2005; Chambers et.al. 2003; Smith et.al. 2001), overtime unfolding of the pattern of R & D benefits (Aboody and Lev 1998) and risks of R & D and valuation ( Herath and Park 1999). But study of flow of causality seems to have escaped the attention of scholars. This prompts our third hypothesisHypothesis 3 : Causality flows from R & D investment/expenditure to sock returns rather than vice versa. …


Control strategy for the modulation of the DC power for Modified HVDC Systems is proposed. A microprocessorbased firing scheme is presented which control the firing angles for modified HVDC converter with by-pass valves. Fast and continuous control of the DC voltage is possible with good operational characteristics. Using table-look-up algorithm to speed up the response, it gives a full range control of the firing angle for both rectifier and inverter modes. The algorithm is experimentally verified and is found to give a very-fast, precise and equidistant control of the thyristor triggering. Harmonic generations into the AC system and the converter reactive voltampere absorption have been reduced. The operations of modified bridge, the control algorithm and the microprocessor implementation are described. Experimental results on a laboratory model compare well with the predicted values.

The generation and robustness of two‐magnon non‐locality and coherence dynamics induced by an open microwave field cavity are investigated in this work. The studied system consists of a two‐sublattice ferrimagnet coupled to a microwave field within an open cavity through its magnetic field component. The robustness of the two‐magnons non‐locality dynamics is analyzed using various non‐locality and coherence measures (namely, uncertainty‐induced non‐locality [UIN], maximal Bell function, and log‐negativity entanglement [L‐NE]) in the presence of the spontaneous emission and the electromagnetic‐wave dissipation. It is shown that photon‐magnon couplings, two‐magnon couplings, and dissipation all have an impact on the dynamical aspect of two‐magnon non‐locality and coherence. This work reveals that the two‐magnon non‐locality and coherence can be generated. For an initial maximal correlated two‐magnon state, the initial UIN non‐locality is shown to be more resilient than the maximum Bell function and log‐negativity. The amplitudes of the two‐magnon non‐locality quantifiers decline as a result of the two‐magnon coupling. The Bell non‐locality and L‐NE are reduced via spontaneous emission and dissipation, but the two‐magnon UIN‐coherence is preserved. These findings contribute to a better understanding of such dynamics and may shed light on measurement estimation in open quantum systems.


The ethanol extract of Hedera helix has been seen to be cytotoxic to splenic lymphocytes due to the presence of saponins whose effect is reduced by addition of serum to the medium. The serum proteins bind to the saponins and reduces its cytotoxic effect. The alcoholic Hedera extract shows cytotoxic effect against Ehrlich ascitic cells. When the extract was injected in tumour bearing mice, tumour disappeared in 83.3% animals. Further treatment by alcoholic Hedera extract on the 16.7% cases of tumour bearing animals where the tumour did not disappear, the plant extract curbed the growth of the tumours and increased the survivality of the animals compared to control animals.


The fortieth anniversary of the founding of the American Society of Mechanical Engineers was celebrated at a meeting held November 5, 1920, at the Engineering Societies Building, 33 West 39th Street, New York. This celebration was one of thirty-two similar meetings held simultaneously in some of the larger cities throughout the country. Messages of congratulations were received from a number of prominent men, including President-Elect Warren G. Harding, Vice-President-Elect Calvin Coolidge, Herbert Hoover, and Charles M. Schwab.


We derive a divergence formula for a group of regularization methods with an L2 constraint. The formula is useful for regularization parameter selection, because it provides an unbiased estimate for the number of degrees of freedom. We begin with deriving the formula for smoothing splines and then extend it to other settings such as penalized splines, ridge regression, and functional linear regression.


Mikhail Bakhtin worked with his enterprising study of the author-hero relation all his life. His works bring the philosophy of dialogism into the discussions of literary works and sees the relationship between the author and the hero in terms of a dialogue. The author should release his power to enable the full blooming of the consciousness, as revealed in language of the hero. With all the characters blooming in their diverse ideologies, the novel can be written in the mode of "polyphony" with its diversity of languages deeply rooted in social life. Nevertheless, the authorial discourse is responsible for the style of the novel. He must be conscientious in the arrangement of characters and settings and meticulous in presenting the structure of the narrative. This study examines those diverse social languages presented in Edith Wharton's The Custom of the Country to testify that the author's voice strikes roots in the formation of a novel. Pointing out Bakhtin's possible mistakes in the discussion of those social languages in Wharton's novel, I want to show that the linguist's persistence in the author-hero dialogical sphere needs to be revised to be more satisfying. Keywords : dialogism, polyphony, discourse, dialogue, old New York aristocracy MARANG Vol. 18 2008 pp. 103-120


This chapter focuses largely on methods of proof of the strong law, building on the fundamental convergence lemma. It covers Kolmogorov's three‐series theorem, strong laws for martingales, and random weighting. Then a range of strong laws are proved for mixingales and for near‐epoch dependent and mixing processes.


A101 an improved multicarrier transmission technique of orthogonal frequency division multiplexing (OFDM), OFDM with index modulation (OFDM-IM) has attracted great attention for its flexible design of the transmission frame and better bit error rate (BER) performance compared with that of classical OFDM. In this paper, we investigate the optimal frequency-domain design of OFDM-IM to achieve the maximum capacity over frequency-selective Rayleigh fading channel. Unlike the conventional OFDM-IM with the same selected probability of each active indices combination (AIC), we select the AICs with different probabilities according the channel state information of the subcarriers. Based on the mutual information associated with each AIC, we propose a Huffman coding based adaptive OFDM-IM to improve the BER performance. Simulations and numerical results demonstrate the proposed Huffman coding based OFDM-IM achieves higher capacity and better BER performance.

Abstract Transient acantholytic dermatosis or Grover's disease, is a dermatosis of unknown aetiology, that typically presents as an erithematous popular eruption with crops of vesicles and crusts over the trunk; in which the most common histopathological finding is the presence of focal acantholysis and dyskeratosis. It affects mostly middle-aged or elderly men. One of the triggering factors most frequently described in the literature is the exposure to sunlight. Four cases have been recently reported of Grover's disease with a new pattern of clinical presentation, characterized by inflamed papules and crusts following sun exposure, along with lentiginous "freckling". They were three middle aged women and a 60 years old man. The histopathological findings coincided in presenting interpapilar ridges elongation associated with focal acantholysis and dyskeratosis. We present a 38 year old female with clinical and histopathological lesions compatible with this new lentiginous pattern of Grover's disease described by Cooper in 2004 (Dermatol Argent 2010;16(2):122-125). Keywords: transient acantholytic dermatosis, Grover´s disease, lentiginous, photosensitivity.

This paper reports our participation for SemEval-2018 Task 7 on extraction and classification of relationships between entities in scientific papers. Our approach is based on the use of a Convolutional Neural Network (CNN) trained on350 abstract with manually annotated entities and relations. Our hypothesis is that this deep learning model can be applied to extract and classify relations between entities for scientific papers at the same time. We use the Part-of-Speech and the distances to the target entities as part of the embedding for each word and we blind all the entities by marker names. In addition, we use sampling techniques to overcome the imbalance issues of this dataset. Our architecture obtained an F1-score of 35.4% for the relation extraction task and 18.5% for the relation classification task with a basic configuration of the one step CNN.


Age and ageing are issues of high significance in our times, and lead us to ask how this prolonged lifespan can be spent in a most self-determined, meaningful and satisfying way. The author's personal approach to working with this age group is described and complemented by personal reflections on this subject. The many objectives include non-musical goals as well as musicoriented objectives which can instigate valuable and satisfying musical experiences of a high quality. Fundamental principles include: becoming a player – taking an active part; the interplay of music, speech, movement and dance; improvisation and forms. Important parts of sessions are described as well as their goals: the greeting ritual is of importance and warm-up exercises can be offered using movement or body percussion. Singing wellknown songs as well as new ones, and playing Orff instruments are valuable activities. Movement is also an important part of the sessions where diverse objects such as gloves, sticks or peacock feathers are used. The Orff approach has the wonderful advantage of being multifaceted, putting emphasis on improvisation and individual creativity which allows making music according to one's own abilities – something that is important for elderly people – and offering many different impulses to feel, to live and physically express music.

The relationship between confidence and accuracy has been modeled many times. This paper compares and contrasts three decision-making mathematical models (2DSD, Poisson, RTCON2) of confidence and investigates how each model predicts the effects of interruptions on accuracy, decision response time, confidence, and confidence response time.


Root competition (tree density), summer pruning, and regulated irrigation were studied to determine whether they can be used to control tree vigor and productivity in ultra-dense orchards of peach [Prunus persica (L.) Batsch]. All methods appeared to inhibit tree growth, but regulated irrigation combined with root competition generated from high tree density was most effective. Fruit yields and fruit growth were significantly increased (up to 30%) by high tree density combined with low rate of water application when water stress limited shoot growth but stimulated subsequent fruit growth. Periods of low rate of water application are specified.

Abstract : Satellite communications are critical to Marine Corps command and control. Capabilities in the domain of beyond line of sight systems, such as wideband SATCOM, must periodically be assessed for alignment with relevant strategy, policy, and doctrinal publications. The National Security Strategy and other documents are periodically updated to provide direction to the U.S. Armed Forces. This thesis provides an analysis of a broad range of publications that extend from national level strategy documents down to service level doctrinal publications that specifically address how the Marine Corps conducts military operations. The focus is to identify how beyond LOS SATCOM systems can support the key tenets of the NSS and USMC doctrine. The analysis forms the basis for an assessment of current USMC SATCOM systems and capabilities, followed by considerations for future USMC SATCOM systems and capabilities. SATCOM provides capacity, range, and coverage that allow expeditionary forces such as the Marine Corps to operate anywhere, anytime. Beyond LOS capabilities allow us to mass effects from fewer, more widely dispersed forces. This thesis provides an analytical foundation to help shape future USMC SATCOM operational concepts. It may then help shape USMC SATCOM requirements that must be satisfied by new systems.


A more precise recommendation plays an essential role in e-commerce. Representation learning has attracted many attentions in recommendation field for describing local item relationships. In this paper, we utilize the item embedding method to learn item representations and user representations. Our methods compute cosine similarity of user vector and recommended item vectors to achieve the goal of personalized ranking. Experiment on real-world dataset shows that our model outperforms baseline model especially when the number of the recommended item is relatively small.


I Progressive muscular atrophy seems to subdivide into secondary groups, which increase in number as clinical observation becomes more attentive and more precise. The form of muscular atrophy that constitutes the subject of this work seems to present characteristics sufficiently definite and stable to merit a special description and a place of its own in nosology. During the past year, we had occasion to observe five patients with this affliction. It is from their symptoms that we shall describe the disease. We shall also have recourse, when necessary, to analogous observations published by other authors [Five case reports follow.] II Now we can try to assemble all the information furnished by these five cases and group them and coordinate them so that a nosologie description emerges containing the main traits of the clinical picture, always so similar in each case. These are the essential points that, in our opinion, distinguish this form of muscular atrophy:


Lipid and DNA are abundant biomolecules with critical functions in cells. The water‐insoluble, amphipathic lipid molecules are best known for their roles in energy storage (e.g., as triglyceride), signaling (e.g., as sphingolipid), and compartmentalization (e.g., by forming membrane‐enclosed bodies). The soluble, highly negatively charged DNA, which stores the cells' genetic information, has proven to be an excellent material for constructing programmable nanostructures in vitro thanks to its self‐assembling capabilities. These two seemingly distant molecules make contact within cell nuclei, often via lipidated proteins, with proposed functions of modulating chromatin structures. Carefully formulated lipid/DNA complexes are promising reagents for gene therapy. The past few years have seen an emerging research field of interfacing DNA nanostructures with lipid membranes, with an overarching goal of generating DNA/lipid hybrid materials that possess novel and controllable structure, dynamics, and function. An arsenal of DNA‐based tools has been created to coat, mold, deform, and penetrate lipid bilayers, affording the ability to manipulate membranes with nanoscopic precision. These membrane engineering methods not only enable quantitative biophysical studies, but also open new opportunities in synthetic biology (e.g., artificial cells) and therapeutics (e.g., drug delivery).


(ProQuest: ... denotes non-US-ASCII text omitted.)David a Prophet, yet in Verse excels:'Twas ECCLESIASTES made the Canticles.1The Cromwellian invasion of Ireland has not been famed for the value of its poetry. And yet, like 'David a Prophet', some of the soldiers, civil servants and divines that have been identified with and resisted the Cromwellian invasion and administration of Ireland did produce a discernable body of religiously orientated verse. The best overview of the writing produced during this period has been provided in Andrew Carpenter's groundbreaking anthology, Verse in English from Tudor and Stuart Ireland (2003), but its selection of a dozen or so examples of material from the 1650s could represent only a small fraction of the decade's poetic output, and, necessarily, could not offer a broader context for its production and reception. The recent edition of Faithful Teate's Ter Tria (1658), edited by Angelina Lynch (2007), reminded scholars that material produced in this period did make significant demands upon its readers and usefully highlighted its complexity, its value, and its relation to the wider English tradition. Nevertheless, the thematic characteristics of the poetry of Cromwellian Ireland can be distinguished from that of earlier periods - most of all in its engagement with the tumult of its contexts, the 'strange alteration of affaires' in the aftermath of the regicide and the English Parliament's campaign to subjugate Ireland.2 This article will outline a context for this body of writing within the changing mentalities of Cromwellian Ireland, and will offer a new model for the interpretation of such principal works as Ter Tria, alongside a reading of other texts, which emerged out of even as they shaped the experiences of invasion and administration in Cromwellian Ireland.IOf course, poetry in English had been written in Ireland long before the Cromwellian invasion: John Derricke and Edmund Spenser are just two of its better-known exponents. But this English-language poetry was not uniquely Protestant in its orientation - Richard Stanihurst, uncle of the Renaissance polymath and Protestant polemicist James Ussher, combined his interest in writing metaphysical lyrics with the literary defence of the Catholic faith at the end of the sixteenth century. While it crossed confessional boundaries, this English-language poetry rarely moved beyond its coterie circulation. But a native literary culture did begin to appear. In the 1630s, Dublin felt like 'a city under the distant but perceptible influence of English-language Renaissance culture ... a city which thought of itself as an intellectual centre'.3 Its new cultural confidence emerged with its first printing of poetry, though it would be another generation and several political revolutions later before those publications appeared in anything other than short runs. The slow development of the publication of poetry can be partly explained by the difficulty of securing access to printing presses. When the teaching staff of Trinity College combined their efforts to produce Musarum Lachrymae (1630), a collection of verse elegising Catherine Fenton, the second wife of Richard Boyle, first Earl of Cork, they benefited from access to the printing facilities of the official stationers' office in Dublin, but most poetry written by Protestants in Ireland continued to be published in London.4 By the 1650s, responding to the new need for the rapid and widespread dissemination of news, printing presses had been established in several of the major Irish towns. But poets' access to publication did not markedly improve: these presses were strictly controlled, and were most often used for official business.5But, throughout the 1650s, and on both sides of the confessional division, English verse published in Ireland did make occasional appearances, and in all manner of literary contexts. At the beginning of the decade, Frances Cook, wife of the regicide judge John Cook, succeeded in finding a publisher for her verse in Cork, though her work, like that of her husband, was later reprinted in London. …


Tomato spotted wilt virus (TSWV) was detected by ELISA within freshly harvested infected tubers of all cultivars tested, but had an erratic distribution which could affect detection reliability. The lack of detectable virus within many tuber eye samples was reflected in production of healthy shoots from infected tubers, some of which did eventually succumb to TSWV infection after 1-4 weeks' growth, and observations suggested this may be enhanced by virus multiplication in diseased shoots produced from the mother tuber. Breeding populations of Thrips tabaci were found within a field exposure trial, and trapping confirmed this as the only known TSWV vector present. In this trial, relying on natural thrips transmission, there was no significant variability in susceptibility of the cultivars tested to initial foliar infection. However, in a glasshouse trial using mechanical inoculation, significant cultivar differences in the rate of foliar systemic infection were observed. Substantial cultivar differences were also found in the efficiency of TSWV translocation from infected plant to tuber, and from infected tuber to progeny plants. Tuber infection rate was further affected by the age of plants at infection, and by the proportion of stems of each plant showing symptoms of TSWV infection. Two apparent resistance mechanisms operated to restrict TSWV translocation to tubers. The first showed strong but incomplete resistance at all ages of challenge; the second showed initial susceptibility to tuber infection but, in challenges after tuber initiation, showed a strong resistance phenotype. Expression of tuber necrosis also varied with cultivar and was affected by plant age at infection. Malformed tubers and secondary growth were also found following foliar TSWV infection, but were not necessarily associated with tuber infection. Current certification tolerance levels for TSWV infection in seed potatoes in Tasmania overestimate the risk of TSWV infection. Given that disease risk varies markedly with cultivar, perhaps certification tolerance levels should reflect this on a cultivar-specific basis.


Objective To explore the correlation between age and left and right ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals.Methods Fifty and seven healthy participants aged from 16 to 74 years were included in the study.Each participant underwent pulsed wave Doppler examination of mitral inflow,tricuspid inflow,then underwent tissue Doppler imaging of the mitral,tricuspid annulus.Results There was good correlation between age and ventricular diastolic function indexes measured by tissue Doppler imaging(r=-0.73,P0.001).Conclusion This study shows that age has important influence on ventricular diastolic function indexes measured by tissue Doppler imaging in normal individuals and should be considered in the evaluation of left and right ventricular diastolic function


Dissabilities is one of the disorders or handycaps in a physic or motoric t experienced by a person which causes movement barriers or social barriers. It is not easy for people with disabilities to overcome both movement and social barriers, but still open strategies to overcome them. The strategy used is usually called the coping strategy. The purpose of this study is to understand and describe the coping strategies for people with disabilities. The research method used was qualitative phenomenology whose data was collected through interviews with 6 informants. The selection of informants was done by purposive sampling technique with the criteria of disabled people who were still in productive age. The results of the study show that coping strategies used by disabled persons can be divided into two forms, namely Emotion Focus Coping and Problem Focused Coping. In other words, it can be stated that persons with disabilities show different strategies for dealing with problems, both the same and different problems. Problems that are often faced by persons with disabilities in the form of abuse or bullying, feel discriminated, feel underestimated because they are considered unable to obtain decent income-earning jobs, often rejected by potential partners because of physical imperfection, experience rejection of families of potential spouses due to imperfection physical experience, getting discriminatory treatment even from his own family. Other findings from this study indicate that people with disabilities have positive way of thinking, and optimistic about facing the future and hope to get a better life in the future. In addition, support from the family makes disabled people become more confident and encourage achievement.


The localization of autonomous vehicles using light detection and ranging (LiDAR) sensors relies on high-definition (HD) maps, which are essential for accurate positioning. However, the large storage capacity required for HD maps poses challenges for real-time performance. To address this issue, we propose a vehicle to infrastructure (V2I)-based LiDAR localization method. In this approach, real-time HD maps are transmitted to vehicles in the vicinity of the infrastructure, enabling localization without the need for map data. We conducted tests to determine the optimal size of the HD maps and the distance between vehicles and the infrastructure, considering the impact on transmission speed. Additionally, we compared the matching performance between the complete HD map and sub maps received from the infrastructure, to evaluate the effectiveness of our method in a qualitative manner.

Rice (Oryza sativa L., 2n=24) belongs to family Poaceaeand subfamily Oryzoidae. It is believed to be originated in South-East Asia. It is the world's most important cereal crop and is the primary source of food and calories for about half of the mankind (Khush, 2005).Rice is life and princess among the cereals, the staple food of 65 per cent of the total population in India. Asia is considered to be "rice bowl" of the world and it produces and consumes more than 90 per cent of world rice.


This work presents a brief review on hearing with cochlear implants with emphasis on music perception. Although speech perception in noise with cochlear implants is still the major challenge, music perception is becoming more and more important. Music can modulate emotions and stimulate the brain in different ways than speech, for this reason, music can impact in quality of life for cochlear implant users. In this paper we present traditional and new trends to improve the perception of pitch with cochlear implants as well as some signal processing methods that have been designed with the aim to improve music perception. Finally, a review of music evaluation methods will be presented.

We study D7 brane probes holomorphically embedded in the Klebanov-Strassler model. Analyzing the κ-symmetry condition for D7 branes wrapping a 4-cycle of a deformed conifold we find configurations that do not break = 1 supersymmetry of the background. We compute the fluctuations of the probe around one of these configurations and obtain the spectrum of vector and scalar flavored mesons in the dual gauge theory. The spectrum is discrete and exhibits a mass gap.


Abstract : A new formulation for chamber flow dynamics in a model of solid rocket engine shows that vorticity generation and convection are prominent physical features of the flow field. Analytical and fully computational methods are employed. to describe a basically inviscid interaction between acoustic disturbances arising from specified boundary disturbances and a sidewall injected flow field which simulates propellant burning. The mathematical model, based on the Navier Stokes equations, is developed in terms of an initial value problem in order to describe the complete, natural chamber flow evolution arising from boundary driven disturbances. The approach is analogous to a direct numerical simulation, although contemporary perturbation methods are employed to extract specific spatial and temporal scales from the equations and boundary conditions. The results show that large unsteady vorticity is created at the injected surface (sidewall) and convects into the cylinder with the radial component of the injection flow velocity.


Geogrids have been successfully used in railroad applications for ballast and sub-ballast stabilization purposes for many decades. When granular material is placed and compacted over the geogrid, aggregate particles interlock within the geogrid and are confined within the apertures. A triangular aperture geogrid was used to stabilize railroad ballast in this study. The performance of the stabilized ballast samples were evaluated in the laboratory using a large scale triaxial test device and strength testing of the geogrid-reinforced ballast samples. Both single and multiple layers of the triangular aperture geogrid were placed at different locations in test specimens to identify optimal application of geogrid for maximizing ballast strength properties. Interestingly, the highest strength was achieved when two triangular aperture geogrids were placed in mid-specimen lateral bulging zone. To further investigate the geogrid reinforcement mechanisms, an imaging based Discrete Element Modeling (DEM) approach was also adopted with the capability to create actual ballast aggregate particles as three-dimensional polyhedron elements having the same particle size distributions and imaging quantified average shapes and angularities. The DEM approach successfully predicted the measured strength properties of the geogrid-reinforced ballast specimens with the geogrids placed at different depths in the cylindrical test specimens.
