Research on Relationship Between Competitive Priorities and Manufacturing Performance Based on Modular Customization

The production mode of modular customization can achieve user's personalization and mass production at the same time,therefore it has gradually become one of the important production modes in the information age.Modular customization can enhance order-winner ability for enterprises,that is competitive priorities.Thus manufacturing enterprises need to pay attention to what kind of competitive priority,and its impact on manufacturing performance has become an important resaerch.Through analysis of the modular customization theory and the competitive priorities theory,this paper proposes the theory hypothesis of relationship between competitive priorities and manufacturing performance in the modular customization.Then,based on International Manufacturing Strategy Survey(IMSS) database,competitive priorities are divided into innovation,quality,flexibility,delivery and cost five elements,and manufacturing performances are divided into time,flexibility,financial and quality in modular customization by using factor analysis,and then on the basis of these results this paper establishes Structural Equation Model(SEM) to research relationship between the competitive priorities and the manufacturing performance in the modular customization.The established Structural Equation Model(SEM) is simulated by AMOS7.0 software,and then it divides the relationship between competitive priorities and manufacturing performance in the modular customization into relevant but not significant,moderate positive correlation and high positive correlation.The results indicate that: there is a positive correlation between competitive priorities and manufacturing performance in the modular customization,but they are different in significant effect in statistics.The results are of both theoretical and practical value for modular customization enterprises to pay more attention to competitive priorities,and then improve their corresponding manufacturing performance.
Adenosine‐Induced Tachycardia: What is the Mechanism?

A 24-year-old woman presented with recurrent episodes of paroxysmai palpitations. She had a documented narrow QRS tachycardia, which was responsive to adenosine. The sinus rhythm ECG was normal. Clinical examination and echocardiogram revealed a structurally normal heart. Adenosine was administered in sinus rhythm to help identity the mechanism of the narrow QRS tachycardia. A bolus of adenosine 12 mg induced self-terminating tachycardia (Fig. 1). What is the mechanism of the tachycardia?
Sine wave synthesis with harmonic-cancellation and single-bit Sigma-Delta modulation

Sinusoidal waveform generation as part of an on- chip built-in self-test (BIST) system typically requires sufficient linearity without excessive hardware overhead. This paper investigates the use of staircase waveform from summation of phase-shifted square waves for sine wave synthesis with its harmonic cancellation properties combined with single-bit sigmadelta modulation for a reduced complexity yet highly digital implementation suitable for such BIST scenario. A prototype system implemented in an Intel Altera Cyclone V FPGA is presented to verify the proposed approach, with experimental results showing the output spectrum of the generated sine wave signal with 44.8-dB spurious-free dynamic range (SFDR) with a system clock running at 50 MHz.
Smartphone applications can help in treatment for alcoholism

Cost-effective continued care for persons with alcohol use disorders is needed, but it can be problematic due to limited resources.1 During the past 20 years there has been a rapid development of computerised interventions within healthcare; in particular, internet-delivered treatments have been tested in a large number of controlled trials for various disorders.2 Recent studies suggest smartphone applications can be effective, although relatively few studies have been undertaken to date.3
Identification of prognostic and subtype-specific potential miRNAs in thymoma.

AIM We performed a study to identify the role of microRNA in thymoma. PATIENTS & METHODS One hundred twenty-three thymoma patients with clinical information and miRNA expression data from The Cancer Genome Atlas were included in the study. Comprehensive bioinformatics analysis was integrated in our analysis. RESULTS & CONCLUSION Seven miRNAs were found to be associated with overall survival (p < 0.001). Another four miRNAs were found to be associated with disease-free survival (p < 0.001). Type C thymoma can be distinguished from nontype C thymoma by miRNAs. Interestingly, seven miRNAs showed both prognostic and subtype-specific potential. Our findings suggest that miRNAs can be used for prognostic prediction and subtype stratification.
Comparative study of the hydration of hydrophilic contact lenses by refractive index and gravimetry.

PURPOSE To compare the percent hydration by wet weight of hydrogel contact lenses given by the manufacturers with the values obtained using the refractive index and the gravimetry methods. METHODS We used a Valentine refractometer to determine the refractive index of new hydrogel contact lenses at equilibrium swelling in the original solution and container. From the refractive indexes we then obtained the percent hydration of the lenses using a previously prepared graph of refractive index vs percent hydration of saccharose in a phosphate buffer solution (pH 7.0). We used an electronic analytical balance of 0.01 mg resolution to obtain the weights of new lenses when dry and at equilibrium swelling dry, and calculated the percent hydration of the lenses from the difference of the wet and dry weights. RESULTS The hydration values of the contact lenses obtained from the index of refraction differed more than those obtained by gravimetry from the values given by the manufacturers. Acuvue lenses were an exception-the difference for them was negligible. CONCLUSION Gravimetry is more accurate, but more cumbersome and time-consuming than the index of refraction for the determination of the hydration of the hydrogel contact lenses. However, when a fast and easy method is required to obtain the approximate hydration of hydrogel contact lenses, the use of the refractive index method can give acceptable results for most applications.
Confirmation and Elimination of Xylose Metabolism Bottlenecks in Glucose Phosphoenolpyruvate-Dependent Phosphotransferase System-Deficient Clostridium acetobutylicum for Simultaneous Utilization of Glucose, Xylose, and Arabinose

ABSTRACT Efficient cofermentation of d-glucose, d-xylose, and l-arabinose, three major sugars present in lignocellulose, is a fundamental requirement for cost-effective utilization of lignocellulosic biomass. The Gram-positive anaerobic bacterium Clostridium acetobutylicum, known for its excellent capability of producing ABE (acetone, butanol, and ethanol) solvent, is limited in using lignocellulose because of inefficient pentose consumption when fermenting sugar mixtures. To overcome this substrate utilization defect, a predicted glcG gene, encoding enzyme II of the d-glucose phosphoenolpyruvate-dependent phosphotransferase system (PTS), was first disrupted in the ABE-producing model strain Clostridium acetobutylicum ATCC 824, resulting in greatly improved d-xylose and l-arabinose consumption in the presence of d-glucose. Interestingly, despite the loss of GlcG, the resulting mutant strain 824glcG fermented d-glucose as efficiently as did the parent strain. This could be attributed to residual glucose PTS activity, although an increased activity of glucose kinase suggested that non-PTS glucose uptake might also be elevated as a result of glcG disruption. Furthermore, the inherent rate-limiting steps of the d-xylose metabolic pathway were observed prior to the pentose phosphate pathway (PPP) in strain ATCC 824 and then overcome by co-overexpression of the d-xylose proton-symporter (cac1345), d-xylose isomerase (cac2610), and xylulokinase (cac2612). As a result, an engineered strain (824glcG-TBA), obtained by integrating glcG disruption and genetic overexpression of the xylose pathway, was able to efficiently coferment mixtures of d-glucose, d-xylose, and l-arabinose, reaching a 24% higher ABE solvent titer (16.06 g/liter) and a 5% higher yield (0.28 g/g) compared to those of the wild-type strain. This strain will be a promising platform host toward commercial exploitation of lignocellulose to produce solvents and biofuels.
Augmentation of a nearest neighbour clustering algorithm with a partial supervision strategy for biomedical data classification

Abstract: In this paper, a partial supervision strategy for a recently developed clustering algorithm, the nearest neighbour clustering algorithm (NNCA), is proposed. The proposed method (NNCA‐PS) offers classification capability with a smaller amount of a priori knowledge, where a small number of data objects from the entire data set are used as labelled objects to guide the clustering process towards a better search space. Experimental results show that NNCA‐PS gives promising results of 89% sensitivity at 95% specificity when used to segment retinal blood vessels, and a maximum classification accuracy of 99.5% with 97.2% average accuracy when applied to a breast cancer data set. Comparisons with other methods indicate the robustness of the proposed method in classification. Additionally, experiments on parallel environments indicate the suitability and scalability of NNCA‐PS in handling larger data sets.
Influence of Tariffs and Non-Tariff Barriers on Ukraine's Imports: Would the WTO Membership Make Change?

The paper estimates the effect of tariffs and non-tariff measures on imports in Ukraine, aiming to determine the sectors sensitive to trade control measures. This sensitivity is then used as a measure of potential responsiveness of sectors towards Ukraine’s membership in the WTO. Results of the panel data analysis show that trade control measures have quite limited impact on imports, while major determinants are production in exporting country and transportation costs, implying that the WTO membership is rather unlikely to provoke significant inflow of goods in the country. The growth in imports due to the WTO membership only is likely in two sectors – leather footwear, and paper and paper products.
Constant temperature control system of standard capacitors

This paper describes a constant temperature control system for high accuracy standard capacitors developed by NIM. The system includes a constant temperature slot and temperature control circuit. Structure, material and some techniques on reducing the heat transfer of the constant temperature slot are discussed. The temperature control circuit based on PID automation control technology is used to control the slot internal temperature. The system has the resolution of 0.002 °C and the fluctuation of ±0.01 °C, and can reduce capacitance variation of the standard capacitors when the environment temperature changes. The system can improve the standard capacitors with higher accuracy and better stability.
The cytogenetic effects of mycoplasma in human leukocyte cultures

To evaluate the possible role of mycoplasma contamination of tissue cultures in virus induced chromosome breakage, human leukocyte cultures were inoculated with three mycoplasma strains; M. salivarium, M. hominis type 2 and M. fermentans. All three strains caused mitotic inhibition when an inoculum of approximately 106 CFU was used, the effect of M. fermentans being less severe than the one produced by the two other strains. Using a lower inoculum of 103 CFU an increase of chromosome breakage could be produced with M. salivarium when the leukocytes were cultivated for five days. No chromosome changes were seen with M. hominis type 2 and M. fermentans.
Mountain Pine Beetle Seasonal Timing and Constraints to Bivoltinism

Mountain pine beetle tree colonization typically occurs in July and August, with completion of a generation one (univoltinism) or two (semivoltinism) years later. In a 2012 publication, Mitton and Ferrenberg suggested that climate change resulted in an unprecedented generation between June and September (a summer generation), with a concomitant shift to two generations in one year (bivoltinism). Although summer generations are not uncommon in this species, completion of a second generation across winter, between September and June, would be required for bivoltinism, a phenomenon not previously observed. Mitton and Ferrenberg showed that a summer generation can occur, but they failed to adequately track cohorts and provided no compelling evidence for bivoltinism. We demonstrate that a winter generation—and hence bivoltinism—would have been physiologically impossible at the high-elevation site used in Mitton and Ferrenberg due to lower thermal developmental thresholds. The mountain pine beetle is indeed being influenced by climate change. To address the challenges of future population outbreaks of this significant tree mortality agent, however, it is imperative to consider evolved, thermally dependent traits that serve to maintain seasonality.
Corporate philanthropy in the UK: altruistic giving or marketing communications weapon?

Controversy surrounds the issue of whether corporate giving should be regarded as pure altruism (with no expectation of reward) or as a hard-headed business investment subject to normal commercial rules. Some research has suggested that UK companies are neither managing their charitable activities professionally nor capitalizing on the marketing opportunities that corporate philanthropy (CP) provides. Conversely, anecdotal and informal survey evidence has emerged implying that British businesses are perhaps far more commercially orientated towards CP than might previously have been supposed. This paper presents the results of a survey of 281 UK corporate donors across a broad range of industries and companies with widely differing turnovers and numbers of employees. It is concluded that many respondent firms recognized clearly the marketing possibilities and advantages that accompany CP, particularly in the image-enhancement and overall public relations (PR) fields. A majority of the sample businesses loc.
Drinking histories in alcohol-use-disordered youth: preliminary findings on relationships to platelet serotonin transporter expression with genotypes of the serotonin transporter.

OBJECTIVE The serotonin (5-HT) transporter (5-HTT) is thought to play a key role in the onset of alcohol use, with potential behavioral and biological mechanisms mediated by the level of 5-HT in the synapse and in cerebral spinal fluid. Although 5-HT dysregulation has been related to poor impulse control, the biological mechanism is unknown, although functional control of the serotonergic system has been shown to be regulated in part by differential expression of the 5-HTT. The gene responsible for encoding 5-HTT has a functional polymorphism at the 5'-regulatory promoter region, which results in two forms: long (L) and short (S). The LL genotype is hypothesized to play a key role in the early onset of alcohol use and may be related to poor impulse control. The objective of this pilot study is to determine whether adolescents with a current alcohol-use disorder (AUD) (N = 21) have platelet measures of the 5-HTT functioning that are related to 5-HTT genotype and poor impulse control. Specifically, we wanted to examine the relationships between the following: platelet 5-HTT and 5-HTT genotype; platelet 5-HTT parameters and age at onset, as well as duration of drinking; and 5-HTT genotype and impulse control. METHOD Adolescents with current AUD were recruited from the community to participate in a cross-section pilot study. RESULTS Our main findings showed significantly higher paroxetine binding (density of 5-HTT) in LL genotype versus S carriers (SS or SL genotypes); also, the LL group had a significantly earlier age at onset of drinking and longer duration of drinking, and poorer impulse control. CONCLUSIONS These findings provide partial support for the hypothesis that, among currently drinking adolescents with an AUD, differential expression of 5-HTT may play an important role in the onset of adolescent AUD.
Power gated SRAM circuits with data retention capability and high immunity to noise: A comparison for reliability in low leakage sleep mode

A new power gated 6T SRAM circuit is proposed in this paper to suppress leakage power consumption in data retention SLEEP mode. A new write assist circuitry is presented to enhance the write margin of the new power gated memory circuit. Design tradeoffs among data stability, power consumption, and write margin are evaluated with different SRAM circuits. The leakage power consumption is reduced by up to 3.84× and the read static noise margin is increased by up to 4.79× with the new memory power gating technique as compared to a previously published power gated 6T SRAM circuit in a UMC 80nm CMOS technology.
"Scenario"-adaptivity for e-service management in heterogeneous networks

A "Situation-Location" aware system has the main task of handling the set of distributed information and resources available within heterogeneous networks to provide a user with seamless and optimized network access to the desired service from any location. A suitable description of Situation&Location and its whole set of variables can be a powerful means to trade-off among user requirements, application constraints, and underlying network conditions. We propose a Multi Agent System able to capture the concept of Situation&Location and perform the task highlighted above. We follow a general-purpose approach with the aim of guaranteeing the highest versatility is possible. The main strength of our proposed system is its "adaptability" that can be achieved without the use of either new terminals or novel technologies. The only requirement is the introduction of a middleware functionality into already existing terminals and into some network servers.
Rheumatoid arthritis of the cervical spine. A long-term analysis with predictors of paralysis and recovery.

We analyzed the cases of seventy-three patients who were managed over a twenty-year period for rheumatoid involvement of the cervical spine and were followed for a minimum of two years, with an average follow-up of seven years. A neurological deficit did not develop in thirty-one patients (Ranawat et al. Class I) and paralysis developed in the remaining forty-two patients: Class II in eleven and Class III in thirty-one. Of the forty-two patients in whom paralysis developed, thirty-five had operative stabilization. Seven patients were managed with a soft cervical collar because they refused or were medically unable to have the operation; all of the had an increase in the severity of the paralysis. The posterior atlanto-odontoid interval and the diameter of the subaxial sagittal canal measured on the cervical radiographs demonstrated statistically significant correlations with the presence and severity of paralysis. All of the patients who had a Class-III neurological deficit had a posterior atlanto-odontoid interval or diameter of the subaxial canal that was less than fourteen millimeters. In contrast, the anterior atlanto-odontoid interval, which has traditionally been reported, did not correlate with paralysis. The prognosis for neurological recovery following the operation was not affected by the duration of the paralysis but was influenced by the severity of the paralysis at the time of the operation. The most important predictor of the potential for neurological recovery after the operation was the preoperative posterior atlanto-odontoid interval. In patients who had paralysis due to atlanto-axial subluxation, no recovery occurred if the posterior atlanto-odontoid interval was less than ten millimeters, whereas recovery of at least one neurological class always occurred when the posterior atlanto-odontoid interval was at least ten millimeters. If basilar invagination was superimposed, clinically important neurological recovery occurred only when the posterior atlanto-odontoid interval was at least thirteen millimeters. All patients who had paralysis and a posterior atlanto-odontoid interval or diameter of the subaxial canal of fourteen millimeters had complete motor recovery after the operation. In this series, although only patients who had a neurological deficit were operated on, we observed the range of the posterior atlanto-odontoid interval that was associated with poor or no recovery after the operation, and we identified the safe range on the basis of the patients in whom paralysis did not develop.

The Hazards of Interaction: When Isolation Benefits Performance

People interact, constantly, and interaction is central to organizational theory and strategic management. Here we focus on one kind: dyadic interactions that may bring one individual to adopt the practices of another. We examine how one’s performance is affected by such interactions. Some scholars, across disciplines and schools, view such interaction as a source of increased individual performance. On this presumption hinge many practices, such as corporate best practices sessions, entrepreneurial incubators, and peer learning. But others disagree, documenting how such interactions can build social pressure, distort practices, and undermine performance. We take a novel path by incorporating recent evidence from two research streams establishing: 1) how people misjudge performance; 2) the extent to which they heed (or ignore) others’ advice. Grounding our assumptions in empirical evidence, we construct an agent-based model and simulate recurring interactions among many. We find that interaction can somet.
Algorithm research for power quality monitoring based on time-frequency analysis theory

Because of the serious pollution in the modern power grid, power quality monitoring and control has become an urgent need to solve the engineering problem. With the application of time-frequency analysis theory of modern digital signal processing, some algorithms are proposed to monitor the disturbance signals like electromagnetic transient vibrating, electromagnetic transient shock, and short-term voltage changing signals in the transient-state power, as well as the harmonic signals carried by steady-state power. Simulation results show that the theory of time-frequency analysis based algorithms can not only analyze the frequency components, but also be able to accurately locate the signal in the transient time for each frequency component appeared, which achieves synchronous measurement for the signal in both time and frequency domain. By choosing a fast DSP chip, an on-line power quality monitoring system can be constructed, which provides significant foundation and basis for the further improvement of power quality.
Medienbruchfreie Kollaboration in Scrum-Meetings

Das in der Softwareentwicklung haufig eingesetzte agile Vorgehensmodell Scrum setzt ein hohes Mas an Kommunikation und Kollaboration voraus. Regelmasig stattfindende Scrum-Meetings stellen die IT-Infrastruktur der Unternehmen vor neue Herausforderungen. Projektoren und Notebooks gehoren zur Standardausrustung von Meeting-Raumen, allerdings fehlt es an Moglichkeiten an den Arbeiten im Prozess des Meetings zu partizipieren und die Tatigkeiten entfernter Teams zu integrieren. Die starke Verbreitung mobiler Gerate bietet neue Potentiale, welche bisweilen haufig ungenutzt bleiben. Dieser Beitrag stellt das Collaboration Surface-System vor, welches die Moglichkeiten der vorhandenen Infrastruktur um mobile Gerate, Multitouch-Tische und weiteren Projektionsflachen erganzt, um so Gruppenarbeit effizienter und erlebbarer zu gestalten.
