A broadcast strategy for the Gaussian slowly fading channel

We investigate a broadcast transmission strategy for the single-user slowly fading Gaussian channel where the channel state is assumed to be known at the receiver end only. This strategy facilitates one to adapt the transmission rate to the actual channel conditions without having any feedback link to the transmitter. In essence this strategy enables one to simultaneously implement a continuum of capacity versus outage values rather than a single pair as is the case in the more standard approach.
Altered default-mode network functional connectivity in college students with mobile phone addiction

Objective: The present study aimed to determine whether Default-Mode Network (DMN) connectivity at resting-state is altered in college students with mobile phone addiction (MPA) by functional magnetic resonance imaging (fMRI). Methods: The fMRI data were acquired during resting state from 24 college students with MPA and 16 ageand gender-matched normal control college students. Synchronized low-frequency fMRI signal fluctuations were monitored to determine posterior cingulate cortex (PCC) connectivity in all subjects. In order to assess the relationship between MPA behavioral features and alteration in functional connectivity, the z value of areas that exhibited abnormal PCC connectivity in 24 subjects with MPA were correlated with the scores of the Self-Rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Barratt Impulsiveness Scale-11 (BIS-11), Rosenberg Self-esteem Scale, Pittsburgh sleep quality index (PSQI), Sensation Seeking (SS), Smartphone Addiction Inventory (SPAI) and Mobile Phone Addiction Index (MPAI). Results: Compared with the control group, functional connectivity in the anterior cingulate, bilateral middle frontal gyrus, bilateral inferior frontal gyrus, right middle temporal gyrus, and right inferior temporal gyrus increased in subjects with MPA. Subjects with MPA revealed higher SAS (P = 0.0293), SDS (P = 0.0056), BIS-11 (P<0.0001), PSQI (P = 0.001), SPAI (P<0.0001) and MPAI (P<0.0001) scores and lower RSS (P = 0.0002) scores, compared to controls. No significant correlations were found between altered functional connectivity and MPA behavioral features. Conclusion: College students with MPA present different behavioral features and DMN functional connectivity, especially in cerebral regions related to cognitive control.
The Code-Centric Collaboration Perspective : Evidence from GitHub

Decentralized Version Control Systems (dvcs) enable teams to structure their development independently, allowing parallel work. Online hosting services for dvcs have become a viable option for teams to structure their workflow around, and GitHub is currently the most widely used such service, hosting over 10 million repositories for open source and proprietary software projects. What are the mechanisms through which the use of dvcs-based workflows supports a team’s collaboration? In our study we decompose collaboration into its elements of coordination, communication, awareness, task division, and conflict resolution. We provide qualitative evidence of teams using GitHub benefitting in terms of collaboration, and explain the benefit by seeing how each collaboration element is supported. We discover that using dvcs goes hand-in-hand with a code-centric collaboration perspective inspired by self-organization and mediating communication and coordination needs.
Applying factor analysis and analytic hierarchy process to evaluate innovation of nonprofit organizations

Although innovation is a critical success factor for any organization, its measurement and evaluation still has not been fully addressed especially in the context of nonprofit organizations (NPOs). This paper aims at integrating factor analysis and analytic hierarchy process (AHP) to evaluate innovation of NPOs. As a result of our literature review, three types of NPOs’ innovation, namely climate for innovation, service innovation, and management innovation were identified. Factor analysis techniques were then performed based on survey data from Chinese NPOs to establish the measurement scale of NPOs’ innovation. Finally, AHP together with a case study was carried out to clarify how to evaluate the proposed measurement scale of NPOs’ innovation.
THE GEOGRAPHICAL AND ECOLOGICAL DISTRIBUTION OF THE BLACK SWIFT IN COLORADO

T HE northern race of the Black Swift (Cypseloides niger borealis) remained undescribed until the year 1857, at which time it was reported by Kennerly, a member of the Pacific Northwest Boundary Survey Expedition, who collected a specimen in the Puget Sound region. It seems remarkable that it could have escaped notice for so long. However, history seems to have repeated itself on a more limited geographical scale, for it was not established that the bird is a breeding species in Colorado until 1949. The breeding range of the northern form of the Black Swift extends from southeastern Alaska southward to southern Mexico, and eastward to much of mountainous Colorado. However, within this vast area, the bird occurs only in isolated colonies due to certain ecological considerations to be discussed later. As far as the winter range is concerned, Bent (1940)) who has written the only fairly complete account of the species? states that it is unknown. Whether the bird spends the winter with the resident form in Central America or goes on to South America is still to be determined. The credit for the initial discovery of the Black Swift in Colorado goes to Frank M. Drew (1881) who collected a specimen along the Animas River a few miles east of the present site of the town of Silverton in San Juan County. He stated that it bred in this locality, but this was an inferential conclusion since he found no nests. This is further borne out by the fact that the nest and egg of the Black Swift were unknown to science until 1901, when A. G. Vrooman found the species nesting along the Pacific Coast west of Santa Cruz, California. Nevertheless, Colorado has been included in the breeding range in the AOU Check-list and elsewhere on this basis up to the present time. The years following Drew’ s discovery produced very few Colorado records, some authentic and some doubtful. In 1882, Drew returned to substantially the same locality and collected a series of 10 individuals, publishing some notes on their plumages during that year. Again, in 1885, he published a short paper on the vertical ranges of birds in Colorado giving 14,000 feet as the upper limit for the Black Swift and stating that it breeds between 10,000 and 12,000 feet. Bendire (1895)) in his “Life Histories of North American Birds,” said that the bird seemed confined to San Juan County and mentioned Anthony’ s correspondence with him concerning observations of the Black Swift around Silverton in the summer of 1853; he also noted Fisher’ s observations of swifts of this species about the cliffs near Trinidad in July 1892, although they have not since been seen there.
Impact of Transformational Leadership on Organizational Commitment , Job Satisfaction and Patient Safety Culture

Patient safety is considered as the most important matter in the medical field as well as the quality of services safety which is also acknowledged as a priority by all health services providers Hospital must be able to create a safety culture in its duty of providing health services, and such culture could be developed by the support of transformational leadership, organizational commitment and job satisfaction. In the previous studies, the patient safety culture was shaped through the transformational leadership, organizational commitment and job satisfaction, use multiple regression analysis, only assessed whether the variables are the predictor of the patient safety culture formation and found that those above was a significant predictor for patient safety culture. In this study, the researchers analyses the impact of transformational leadership on organizational commitment, job satisfaction, and patient safety culture which were not previously studied. The objective of the study; first, to find out to what extent the impact of transformational leadership on organizational commitment; second, to find out to what extent the impact of transformational leadership on job satisfaction; and third, to find out to what extent the impact of organizational commitment and job satisfaction on patient safety culture. The study used a questionnaire which was distributed to 105 respondents who are all the nursing staff providing direct contact and services to the patients in a private hospital in Tangerang, Indonesia. The method of the data analysis of this study is the Structure Equation Model (SEM). The result of the study found that the transformational leadership had an impact towards the increase in organizational commitment and jobs satisfaction and the study found that there was an impact of organizational commitment and job satisfaction on patient safety culture. So, it is concluded that the formation of patient safety culture is impacted by both organizational commitment and job satisfaction. While the organizational commitment and job satisfaction are impacts by the transformational leadership.
Development of a Computer System for Simulation of Traffic Models

In this paper, a computer system named Advanced Emulator (AE), which is developed for simulation of traffic models, is presented. Unlike traditional transportation programs such as PARAMICS and VISSIM, AE has no built-in concrete traffic models. Instead, AE implements a specialized scripting language, the AE language, through which researchers write scripts defining logic of concrete traffic models to be simulated by themselves, and a runtime virtual machine, the AE virtual machine, which interpret and execute scripts written in the AE language to fulfill simulation. Thus, AE provides researchers a platform on which they can build customized simulation packages for various traffic models from the ground up. Using AE, researchers can virtually simulate any traffic model from car following and lane changing to ramp metering. Therefore, AE could be a useful tool in research fields of traffic model comparison, prototyping, and validation.
A P ] 3 0 M ay 2 01 9 Sobolev embeddings with weights in complete riemannian manifolds

We prove Sobolev embedding Theorems with weights for vector bundles in a complete riemannian manifold. We also get general Gaffney’s inequality with weights. As a consequence, under a "weak bounded geometry" hypothesis, we improve classical Sobolev embedding Theorems for vector bundles in a complete riemannian manifold. We also improve known results on Gaffney’s inequality in a complete riemannian manifold.
Tweets and Votes, a Special Relationship

As the microblogging service Twitter becomes an increasingly popular tool for politicians and general users to comment on and discuss politics, researchers increasingly turn to the relationship between tweets mentioning parties or candidates and their respective electoral fortunes. This paper offers a detailed analysis of Twitter messages posted during the run-up to the 2009 federal election in Germany and their relationship to the electoral fortunes of Germany’s parties and candidates. This analysis will focus on four metrics for measuring the attention on parties and candidates on Twitter and the relationship to their respective vote share. The metrics discussed here are: the total number of hashtags mentioning a given political party; the dynamics between explicitly positive or explicitly negative mentions of a given political party; the total number of hashtags mentioning one of the leading candidates, Angela Merkel (CDU) or FrankWalter Steinmeier (SPD); and the total number of users who used hashtags mentioning a given party or candidate. The results will show that during the campaign of 2009 Twitter messages commenting on parties and candidates showed little, if any, systematic relationship with subsequent votes on election day. In the discussion of the results, I will raise a number of issues that researchers interested in predicting elections with Twitter will have to address to advance the state of the literature.
A Study on Control Strategy of Starting and Shifting Process for Tractor AMT System

In this paper, the working principle of the system is analyzed in order to realize the automatic control of tractor automated mechanical transmission (AMT). The AMT integrated control strategy which includes starting and shifting process is designed according to the special working condition of tractor. In terms of the reliability of the automatic control, the open-loop control time sequence is put forward. The simulation model of the system and control strategy is established and the simulation analysis is done for starting and shifting process of the tractor AMT. It is shown that with using the integrated control strategy of tractor AMT, the effect of the starting and shifting process is satisfactory.
Assessing the effect of irrigation with different levels of saline magnetic water on growth parameters and mineral contents of pear seedlings

A pot experiment was conducted during the 2012 and 2013 seasons at Kanater Horticultural Research station, Qalubia Governorate, Egypt, to determine the effects of irrigation with different levels of water salinity i.e. 1000, 2000, 3000, 4000 and 5000 ppm as well as fresh water combined with magnetized water technology (with or without) on growth parameters and some mineral contents of pear seedlings. Obtained results show that the irrigation by magnetic water increased significantly plant height, no. of leaves / plant as well as fresh and dry weight, root fresh weight lowest and highest 2 mm as well as survival rate, N and P% of pear seedlings than those grown nonmagnetic water in both seasons. While, the same results were achieved concerning with Na and Mg % of pear seedlings in the 1 season and, Fe, Zn, Ca, Mg and B content in the 2 one. Prolein increased by irrigation with non magnetic water compared with magnetic one in both seasons.Generally, the plant height, fresh and dry weight, no. of branch and no. of leaves / plant, root fresh weight lowest and highest 2 mm as well as survival rate of pear seedlings were increased significantly by using irrigation water salinity at the concentration of 1000 ppm or fresh water in two seasons. Vice versa, the lowest ones were recorded by increasing water salinity up to the highest levels (5000 ppm and 4000 ppm) in both seasons. Increasing water salinity up to 5000 and /or 4000 ppm increased significantly prolien, N, P and K % as well as Fe, Mn, Zn, Cu, B, Na, Mg and Ca of pear seedlings , while, the lowest ones were recorded by irrigation with fresh water or the lowest salinity level (1000) ppm in both seasons. In most cases, the growth parameters (shoot and root) of pear seedlings were improved significantly by using magnetic technology with lowest salinity of irrigation water 1000 ppm fresh water while, the opposite trend was recorded by raising salinity up to 4000 and 5000 ppm without magnetic technology in both seasons. Conversely, increasing water salinity up to 4000 and 5000 ppm with magnetic technology gave the highest values of macro and micronutrients as well as prolien % of pear seedlings in two seasons.
A FACE RECOGNITION USING LINEAR -DIAGONAL BINARY GRAPH PATTERN FEATURE EXTRACTION METHOD

Face recognition is one the most interesting topic in the field in computer vision and image processing. Face recognition is a processing system that recognizes and identifies individuals human by their faces. Automatic face recognition is powerful way to provide, authorized access to control their system. Face recognition has many challenging problems (like face pose, face expression variation, illumination variation, face orientation and noise) in the field of image analysis and computer vision. This method is work on feature extraction part of face recognition. New way to extract face feature using LD-BGP code operator it is like LGS and LBP feature extraction operator. In our LD-BGP-code operator work in two direction first linear then diagonal. In both direction, its create eight digits code to every pixel of image. Means of these two directional are taken so that is cover all neighbor of center pixel. First linear direction, only horizontal and vertical pixel are taken. Second diagonal direction only diagonal pixels taken. In matching phase, we use Euclidean distance to match a face image. We perform the Linear and diagonal directional operator method on face database ORL. We get accuracy 95.3 %. LD-BGP method also works on different type image like illuminated and expression variation image.
Association between depth of anesthesia and postoperative outcome : a systematic review and meta-analysis

Background: The bispectral index (BIS) monitor has increasingly been used to measure anesthetic depth to reduce the incidence of intraoperative awareness with recall (AWR). Studies reported conflicting results on the association between anesthetic depth and risk of clinical outcomes after surgery. Objective: We aimed to examine the association between low BIS or triple low state and risk of postoperative mortality and complications by conducting a meta-analysis of prospective cohort studies. Methods: We comprehensively searched PubMed and all available randomized controlled trials (RCTs) and retrospective comparative studies were retrieved. Results: 2 RCTs and 9 retrospective studies met the selection criteria, among which 9325 patients were studied on low BIS, 54160 patients were studied on triple low state. The synthesis of studies pointed to a statistically significant positive association between prolonged exposure to low BIS and increased intermediate mortality (relative risk [RR], 1.10; 95% confidence interval [CI], 1.05 to 1.15, per hour). On the contrary, significant association was noted neither between triple low state and higher 30-day mortality risk (RR, 1.08; 95% CI, 1.00 to 1.17, per 15 min), nor between low BIS duration and postoperative wound infection or major complications (RR: 1.28; 95% CI, 0.69 to 2.41, and RR: 1.72; 95% CI, 0.43 to 6.87, respectively). Conclusions: Cumulative duration of low BIS was associated with an increased risk of mortality. Given the inherent limitations of the included studies, future cohort studies adjusting for a variety of meaningful confounders and well-designed large scale RCTs are waited before sound conclusions are drawn.
Study on Wide-Area Backup Protection for Power systems

Protective relays, pivotal devices that can quickly identify and isolate fault area in power systems, is of great importance for power network security and reliability. When the primary protection has failed to clear the fault or mal-operation condition, the backup protection must ensure fault clearance to prevent the widespread influence to the healthy part of the system. Studies on several well-known blackouts reveal that protective relays are involved and the most troublesome ones are backup protective relays. In this paper the limitation of traditional backup protections is detailedly investigated first. Then a new wide-area backup protection system based on data exchange and coordinate operation among backup protective relays is presented. The backup protection system is designed with the following performance: coordination and acceleration among backup protection to clear faulty component, ability to distinguish inner fault and flow transferring, adaptive protection-setting on-line according to network operational condition. The structure of wide area backup protection system is also described in the end.
Total endoscopic free flap harvest of a serratus anterior fascia flap for microsurgical lower leg reconstruction

Background: A tremendous number of free flaps have been developed in the past. As the surgical result depends not only on a successful flap Alfons Erdmann Wolfgang Koegst transfer but also on the harvest, this paper details the procedures for undertaking the first total endoscopic harvest of a serratus fascia flap for free flap transplantation to the lower leg. 1 Plastische Chirurgie im Eduardus – Köln, Praxis Dr. A. Erdmann, Köln, Germany Patient and methods: In September 2012 we performed the first total endoscopic serratus anterior fascia free flap harvest. The incision of 2.5 cm length was made 10 cm in front of anterior muscle border of the latissimus dorsi at level with the midthorax. After insertion of a flexible laparoscopic single port systemwe started CO2 gas insufflation. We used this setting to meticulously prepare a neo cavity between M. latissimus dorsi andM. serratus anterior. The vessels were dissected and the thoraco-dorsal nerve was separated. With a second auxiliary incision we used a clamp to support the raising of the fascia flap from the underlying muscle. Finally we clipped the vessels to the latissimus dorsi muscle and the flap vessels at the Arteria and Vena axillaris. The flap was extracted via the 2.5 cm incision. Results: We were able to perform a total endoscopic harvest of a serratus fascia flap for free flap reconstruction of soft tissues. With this new operative technique we were able to avoid a long skin incision, which in our view lowers the morbidity at the harvest area. Conclusion:We describe a newmethod for the total endoscopic harvest of the serratus fascia flap for free flap transfer. The flap was harvested within reasonable time and following surgery leaves the patient with minimal donor site morbidity compared to the open technique.
Plant Regeneration through Somatic Embryogenesis from Callus-derived PLBs of Tropical Slipper Orchid ( Paphiopedilum niveum ( Rchb . f . ) Pfitz . )

We have developed a protocol for the indirect production of protocorm-like bodies (PLBs) from germinating seeds and subsequently regenerated plants of a slipper orchid (Paphiopedilum niveum (Rchb.f) Pfitz. ). To solve the serious problem of necrosis that occurs during normal culture and the subsequent stages of development, the incorporation of activated charcoal (AC) and polyvinylpolypyrrolidone (PVPP) into the culture media during the stage of callus induction was also examined. Embryogenic callus was induced from the germinating seeds and showed no browning or only a few necrotic tissues on modified Vacin and Went (VW) solid medium supplemented with 0.1 mgl 1-phenyl-3-(1,2,3-thiadianol-5-yl) urea (thidiazuron) (TDZ), 1 mgl 2,4-dichlorophenoxyacetic acid (2,4-D) and 0.2% AC. These calli developed further along the route for production of PLBs on modified VW medium containing a combination of plant growth regulators (0.1 mgl 1-napthaleneacetic acid (NAA) and 0.5 mgl TDZ) and 1% sucrose. The regenerated PLBs eventually formed the highest number of shoots and roots on modified Murashige and Skoog (MS) solid medium supplemented with 20 and 50 gl banana homogenate, respectively. About 90 regenerated shoots were obtained from about 10 mg of initial PLBs. Samples of the obtained plantlets grew well after being transplanted into mini-pots placed in a shaded greenhouse. A histological study showed that PLBs originated from the surface of the embryogenic callus. Some PLBs could produce secondary PLB resulting in greater PLB proliferation. The PLB-derived plantlets had shoot and root poles indicating that plant regeneration could be considered as a pathway for somatic embryogenesis. _____________________________________________________________________________________________________________
