    A dynamic threshold-based Call Admission Control (CAC) scheme used in wireless/mobile network for multi- class services is proposed. In the scheme, each class's CAC thresholds are solved through establishing a reward-penalty model which strives to maximize network's revenue. In order to lower Handoff Dropping Probability (HDP), the scheme joints packet and connection levels Quality of Service constraints, designing a bandwidth degradation algorithm to accept handoff calls by degrading existing calls' bandwidth during network congestion. Analyses show that the CAC thresholds change adaptively with the average call arrival rate. The performance comparison shows that the proposed scheme outperforms the Mobile IP Reservation scheme.

    Full Text Available In this study, we propose to design a call admission control algorithm which schedules the channels for Real time and non-real time users. In Long Term Evolution (LTE 3GPP Networks, several works were done on call admission control but these works rarely considers scheduling of resources to the real time and non-real time users.When the system meets traffic oriented performance degration, maximum resources are utilized for load balancing and to maintain the consistent quality. In order to avoid the channel degradation and improve the Quality of Service (QoS, the call requests are classified into New Call (NC request and Handoff Call (HC request and the type of services are classified as VoIP and video. Then based upon the Received Signal Strength (RSS value, the channel is estimated as good channel or bad channel. Resource allocation is made for VoIP users based on traffic density. Then non-VoIP users and the non-real time users are allocated resource blocks using the channel condition based marginal utility function. When there are no sufficient resources to allocate, it allocates the resources of bad channel users there by degrading their service. We have designed the network topology with G (n and B (n for representing the available good and bad channels. We investigate the performance degradation when the real time, Non real Time, video and VOIP environments based on RSS threshold value.Comparison is made with the VOS in terms of the paramenters like throughput,bandwidth,delay,fairness and rate. Our proposed method provides good performance and quality.From our simulation results we show that this admission control algorithm provides channel quality and prioritizes the handover calls over new calls which allocates resources to all kinds of users.

    Full Text Available This paper presents the signal-to-interference plus noise ratio (SINR-based call admission control (CAC as an effective technique that guarantees signal quality for admitted users. We propose a CAC model that admits users as long as the SINR exceeds a threshold (th SINR . To reduce blocking, we ensure that the threshold level is maintained at a lower bound (lb thSINR −, convenient to keep the blocking probability ( Pb below a maximum value ( Pb−max. We simulate the CAC model with the Java programming language and evaluate the performance of the model. Simulation results show that our CAC scheme produce the expected performance that improves the network quality.

    2013-01-01

    Call Admission Control (CAC) and Dynamic Channel Assignments (DCA) are important decision-making problems in mobile cellular communication systems. Current research in mobile communication considers them as two independent problems, although the former greatly depends on the resulting free channels obtained as the outcome of the latter. This book provides a solution to the CAC problem, considering DCA as an integral part of decision-making for call admission. Further, current technical resources ignore movement issues of mobile stations and fluctuation in network load (incoming calls) in the control strategy used for call admission. In addition, the present techniques on call admission offers solution globally for the entire network, instead of considering the cells independently.      CAC here has been formulated by two alternative approaches. The first approach aimed at handling the uncertainty in the CAC problem by employing fuzzy comparators.  The second approach is concerned with formulation of CAC ...

    2011-04-01

    Full Text Available In this paper, a GCAD-CAC (Greedy Choice with Bandwidth Availability aware Defragmentation algorithm is proposed. It is able to guarantee respect for data flow delay constraints defined by three different traffic classes. To achieve good results, the algorithm tries to accept all the new requests, but when a higher priority request is received, a lower priority admitted request is preempted. This preemption can leave some small gaps which are not sufficient for new connection admission; these gaps can be collected by the GCAD algorithm by activating a bandwidth availability based defragmentation process. The quality of the algorithm is shown by a comparison with two other algorithms found in the literature.

    Full Text Available The implementation of efficient call admission control (CAC algorithms is useful to prevent congestion and guarantee target quality of service (QoS. When TCP protocol is adopted, some inefficiencies can arise due to the peculiar evolution of the congestion window. The development of cross-layer techniques can greatly help to improve efficiency and flexibility for wireless networks. In this frame, the present paper addresses the introduction of TCP feedback into the CAC procedures in different nonterrestrial wireless architectures.

    2016-06-01

    Handoff management has been an important but challenging issue in the field of wireless communication. It seeks to maintain seamless connectivity of mobile users changing their points of attachment from one base station to another. This paper derives a call admission control model and establishes an optimal step-size coefficient (k) that regulates the admission probability of handoff calls. An operational CDMA network carrier was investigated through the analysis of empirical data collected over a period of 1 month, to verify the performance of the network. Our findings revealed that approximately 23 % of calls in the existing system were lost, while 40 % of the calls (on the average) were successfully admitted. A simulation of the proposed model was then carried out under ideal network conditions to study the relationship between the various network parameters and validate our claim. Simulation results showed that increasing the step-size coefficient degrades the network performance. Even at optimum step-size (k), the network could still be compromised in the presence of severe network crises, but our model was able to recover from these problems and still functions normally.

  11. Power Control Technique for Efficient Call Admission Control in Advanced Wirless Networks

    2012-06-01

    Full Text Available In 4G networks, call admission control techniques have been proposed to provide Quality of Service (QoS in a network by restricting the access to network resources. Power control is essential in call admission control in order to provide fair access to all users, improve battery lifetime and system performance. But the existing call admission control algorithms rarely consider the power controlling techniques in the handoff process for different traffic classes. In this paper, we propose to develop a power controlled call admission control scheme for handoff in the advanced wireless networks. The incoming call measures the initial interference on it and then the base station starts transmitting the packets to the new call. The new call is rejected when the interference reaches a threshold value.Whenever an existing call meets the power constraint, the transmit power is decremented based on thetraffic class and incoming call obtains this information by monitoring the interference received on it. Theconvergence of the power control algorithm is checked and the power levels of all incoming calls areadjusted. From our simulation results we prove that this power control technique provides efficienthandoff in the 4G networks by increasing the throughput and reducing the delay of the existing users.

    2007-11-01

    Full Text Available We propose a two-level call admission control (CAC scheme for direct sequence code division multiple access (DS-CDMA wireless networks supporting multimedia traffic and evaluate its performance. The first-level admission control assigns higher priority to real-time calls (also referred to as class 0 calls in gaining access to the system resources. The second level admits nonreal-time calls (or class 1 calls based on the resources remaining after meeting the resource needs for real-time calls. However, to ensure some minimum level of performance for nonreal-time calls, the scheme reserves some resources for such calls. The proposed two-level CAC scheme utilizes the delay-tolerant characteristic of non-real-time calls by incorporating a queue to temporarily store those that cannot be assigned resources at the time of initial access. We analyze and evaluate the call blocking, outage probability, throughput, and average queuing delay performance of the proposed two-level CAC scheme using Markov chain theory. The analytic results are validated by simulation results. The numerical results show that the proposed two-level CAC scheme provides better performance than the single-level CAC scheme. Based on these results, it is concluded that the proposed two-level CAC scheme serves as a good solution for supporting multimedia applications in DS-CDMA wireless communication systems.

    In order to achieve the Quality of Service (QoS) provisioning and efficient resource utilization in cellular network and Wireless Local Area Network (WLAN) integration, an Integrated Service-Based Call Admission Control (ISB-CAC) scheme is proposed in this paper. The integrated network is modeled by using multi-dimensional Markov chains. The numerical analysis is presented to evaluate the important performance measures such as the blocking probability of originating calls, the dropping probability, and the average transfer time, etc. The steady-state probabilities of the multi-dimensional Markov chains are obtained by using an iterative approach, and the CAC parameters are optimally designed. The analytical model is validated by the computer simulation. It is shown that compared with the conventional WLAN-First Call Admission Control (WF-CAC) scheme, the proposed ISB-CAC scheme not only provides better QoS for mobile users but also utilizes the bandwidth resources more efficiently.

    Full Text Available The Next Generation Wireless Networks (NGWN will be heterogeneous in nature where the different Radio Access Technologies (RATs operate together .The mobile terminals operating in this heterogeneous environment will have different QoS requirements to be handled by the system. These QoS requirements are determined by a set of QoS parameters. The radio resource management is one of the key challenges in NGWN.Call admission control is one of the radio resource management technique plays instrumental role in ensure the desired QoS to the users working on different applications which have diversified QoS requirements from the wireless networks . The call blocking probability is one such QoS parameter for the wireless network. For better QoS it is desirable to reduce the call blocking probability. In this customary scenario it is highly desirable to obtain analytic Performance model. In this paper we propose a higher order Markov chain based performance model for call admission control in a heterogeneous wireless network environment.

    Full Text Available Wireless/mobile communication systems are becoming increasingly popular in recent years. As the wireless resources are scarce, it is important to allocate resources efficiently and carefully, in order to achieve maximum output. The call admission control schemes play a significant role in providing the desired quality of service (QoS by judiciously assigning the radio channels that are available in a micro cell. In this paper, we present two call admission control (CAC schemes for wireless mobile network, (i Prioritized call admission control (PCAC scheme (S1 and (ii Prioritized call admission control scheme with releasing function (S2. Both schemes support integrated traffic i.e. data and voice for both new and handoff attempts. Guard channel concept is used to give the priority to the handoff attempts. To admit more handoff attempts in the cellular system, buffering process is used for the handoff attempts. The concept of balking and reneging is also incorporated for both the schemes. The calls arrive in poisson fashion whereas channel holding time and cell residence times are exponentially distributed. The arrival rate of handoff attempts is computed by using iterative algorithm. Various performance metrics such as blocking probability of new call, blocking probability of handoff data/voice attempts, time out probability of handoff data/voice attempts, force termination probability of handoff data/voice attempts, waiting time of handoff data/voice attempts, carried load, etc. are determined. The sensitivity analysis has also been carried out to facilitate the insights of controllable parameters for real time systems

    As the increasing demand of the capacity of cellular networks, the cell sizes have become smaller than ever, which increases the probability of handoff one may experience during a service. To ensure the calls, QoS and high channel utilization, an effective call admission control is needed urgently. The well-known Guard channel method (GCM) which works with static fashion cannotadapt to the changes in traffic pattern, whereas, SDCA mechanism proposed by S. Wu can overcome that shortcoming due to its dynamic nature. Unfortunately, it is only suitable for single-service. In this paper, we establish a novel stochastic model to study the actual system so as to avoid coping with the complex multiple dimensions stochastic problem. Two wonderful features of the model make it competent for this role. On one hand, it can turnthe multiple steps of state transition into single step ofstate transition, which is a necessary condition for ideal birth-death processes. On the other hand, it can providea simple method to compute the approximation of the call dropping probabilities for multiple services, which facilitate our estimation for the acceptance ratio vector subject to QoS requirement. As a result, we get a multi-services dynamic call admission scheme to adapt for multiple types of services in mobile wireless networks. Numerical results show that our scheme steadily satisfies the constraint on call dropping probability of multi-services while maintaining a high channel throughput.

    2005-01-01

    In high-rate short-range wireless networks,CAC (Call admission control) scheme plays an important role in quality of service provisioning for adaptive multimedia services. Three functions, namely bandwidth satisfaction function, revenue rate function and bandwidth reallocation cost function, are firstly introduced. Based on these functions, an efficient CAC scheme, the Rev-RT-BRA (Reservation-based and Revenue test with Bandwidth reallocation) CAC scheme is proposed. The main idea is that it reserves some bandwidth for service classes with higher admission priority. The performance of the Rev-RT-BRA CAC scheme is analyzed by solving a multidimension Markov process. Both the numerical and simulation results are given. The advantages of the proposedRev-RT-BRA CAC scheme are as follows. (1) It maximizes the overall bandwidth satisfaction function at any system state. (2) It solves the unfairness problem in admitting multiple classes of services with different bandwidth requirenlents. (3) The required admission priority level can be guaranteed for various classes of services.

    Full Text Available We examine the problem of accepting a new request for a pre-stored VBR video stream that has been smoothed using any of the smoothing algorithms found in the literature. The output of these algorithms is a piecewise constant-rate schedule for a Variable Bit-Rate (VBR stream. The schedule guarantees that the decoder buffer does not overflow or underflow. The problem addressed in this paper is the determination of the minimal time displacement of each new requested VBR stream so that it can be accommodated by the network and/or the video server without overbooking the committed traffic. We prove that this call-admission control problem for multiple requested VBR streams is NP-complete and inapproximable within a constant factor, by reducing it from the VERTEX COLOR problem. We also present a deterministic morphology-sensitive algorithm that calculates the minimal time displacement of a VBR stream request. The complexity of the proposed algorithm along with the experimental results we provide indicate that the proposed algorithm is suitable for real-time determination of the time displacement parameter during the call admission phase.

    Admission control plays an important role in providing QoS to network users. Motivated by the measurement-based admission control algorithm, this letter proposed a new admission control approach for integrated service packet network based on traffic prediction. In the letter, FARIMA(p, d, q) models in the admission control algorithm is deployed. A method to simplify the FARIMA model fitting procedure and hence to reduce the time of traffic modeling and prediction is suggested. The feasibility-study experiments show that FARIMA models which have less number of parameters can be used to model and predict actual traffic on quite a large time scale. Simulation results validate the promising approach.

    Full Text Available IP based voice transmission technology is a flexible, simpler and a cost effective implementation of voicetransmission. It provides a real convergence of various networks. This voice transmission technology doesnot support a quality that is equivalent to digitized voice, which is available in the existing PSTN networks.In addition to this, data network vulnerabilities affect the VOIP service causing a drop in the utilization ofvoice communication. In this paper, the quality of service for voice calls is ensured with the integration ofCAC mechanism with the bandwidth link utilization which makes an estimation of the demandedbandwidth. In terms of security, prevention of ARP cache poisoning attack is achieved by use of the signedMAC address response in local area networks. It makes the network confident that the admitted user is anauthorized user and also it verifies that only the authorized users’ information is exchanged over the localarea network. Also an approach that makes it difficult for the hacker’s to hack the data exchanged over thequality channel has been proposed.

    Full Text Available Experience-based admission control (EBAC is a hybrid approach combining the classical parameter-based and measurement-based admission control. EBAC calculates an appropriate overbooking factor used to overbook link capacities with resource reservations in packet-switched networks. This overbooking factor correlates with the average peak-to-mean rate ratio of all admitted traffic flows on the link. So far, a single overbooking factor is calculated for the entire traffic aggregate. In this paper, we propose typespecific EBAC which provides a compound overbooking factor considering different types of traffic that subsume flows with similar peak-to-mean rate ratios. The concept can be well implemented since it does not require measurements of type-specific traffic aggregates. We give a proof of concept for this extension and compare it with the conventional EBAC approach. We show that EBAC with type-specific overbooking leads to better resource utilization under normal conditions and to faster response times for changing traffic mixes.

In this paper, we present a simple reservation protocol and a scalable admission control algorithm, which can provide QoS guarantees to individual flows without per-flow management in the network core. By mapping each flow to a definite time, this scheme addresses the problems that limit the effectiveness of current endpoint admission control schemes. The overall admission control process is described. Analysis is used to explain the reasonability of our scheme and simulation validates its performance.

    To provide scalable and simple Quality of Service(QoS) mechanism for multicast services,Probe-Based Multicast Admission Control (PBMAC) scheme was proposed. In this paper, PBMAC is studied and a so-called subsequent request problem is found in PBMAC, which degrades system performance significantly when the network traffic is heavily loaded. Based on the analysis on subsequent request problem, an Enhance PBMAC (EPBMAC) scheme is proposed, in which complementary probing is devised to solve the problem. Using a new metric of normalized requested equivalent link capacity, the performance of PBMAC and EPBMAC is analyzed and evaluated. Two implementations are proposed for incremental deployment. The paper finally introduces evaluation with packet-based simulations. Both analytical and simulation results show the significant improvement in performance.

    The telephony over IP (ToIP) is becoming a new trend in technology widely used nowadays in almost all business sectors. Its concepts rely on transiting the telephone communications through the IP network. Today, this technology is deployed increasingly what the cause of emergence of companies is offering this service as Switzernet. For several highly demanded destinations, recently fake vendors appeared in the market offering voice termination but providing only false answer supervision. The answered signal is returned immediately and calls are being charged without being connected. Different techniques are used to keep the calling party on the line. One of these techniques is to play a record of a ring back tone (while the call is already being charged). Another, more sophisticated technique is to play a human voice randomly picked up from a set of records containing contents similar to: hello, hello, I cannot hear you Apart the fact that the fallaciously established calls are charged at rates of real calls,...

    Full Text Available Abstract Background Next-generation sequencing systems are capable of rapid and cost-effective DNA sequencing, thus enabling routine sequencing tasks and taking us one step closer to personalized medicine. Accuracy and lengths of their reads, however, are yet to surpass those provided by the conventional Sanger sequencing method. This motivates the search for computationally efficient algorithms capable of reliable and accurate detection of the order of nucleotides in short DNA fragments from the acquired data. Results In this paper, we consider Illumina’s sequencing-by-synthesis platform which relies on reversible terminator chemistry and describe the acquired signal by reformulating its mathematical model as a Hidden Markov Model. Relying on this model and sequential Monte Carlo methods, we develop a parameter estimation and base calling scheme called ParticleCall. ParticleCall is tested on a data set obtained by sequencing phiX174 bacteriophage using Illumina’s Genome Analyzer II. The results show that the developed base calling scheme is significantly more computationally efficient than the best performing unsupervised method currently available, while achieving the same accuracy. Conclusions The proposed ParticleCall provides more accurate calls than the Illumina’s base calling algorithm, Bustard. At the same time, ParticleCall is significantly more computationally efficient than other recent schemes with similar performance, rendering it more feasible for high-throughput sequencing data analysis. Improvement of base calling accuracy will have immediate beneficial effects on the performance of downstream applications such as SNP and genotype calling.

    Admission control algorithm is a key component of a media server which supports Quality of Service(QoS).In this paper we present an admission control algorithm that exploits the elastic properties of the user requirements and the changing properties of system conditions.The characteristic of the algorithm can be expounded from these aspects:First,it provides multiple services to satisfy the different users' requirements regarding QoS and price.Second,it uses a worth function to select from media services with different QoS characteristics in the negotiation process.Finally,it employs a novel price policy to compute the charge for the service,which has a great effect on restricting the greediness of the users and therefore increase the overall user benefit.In the end of the paper,we compare the user benefit attained by our algorithm with that of other method.

    Full Text Available IEEE 802.16 networks are going to provide broadband wireless access with quality of service (QoS guarantee. In all of services, real-time video traffic plays an impeditive role because of its varying bit-rate and stringent delay constraint. To the best of our knowledge, no call admission control (CAC and scheduling schemes cover throughput expectation, delay constraint and fairness requirement simultaneously. In this paper, by taking advantage of traffic periodicity and regularity, a set of CAC and scheduling schemes for real-time video traffic in IEEE 802.16 networks is proposed. Specifically, two key parameters are studied to compromise throughput and delay, as well as, delay and fairness. Simulations with real life video traces show that the proposed schemes may well bear flexibility in balancing throughput, delay and fairness, or, offering significant throughput improvement with acceptable delay and fairness.

    Full Text Available Social relations involve both face-to-face interaction as well as telecommunications. We can observe the geography of phone calls and of the mobility of cell phones in space. These two phenomena can be described as networks of connections between different points in space. We use a dataset that includes billions of phone calls made in Colombia during a six-month period. We draw the two networks and find that the call-based network resembles a higher order aggregation of the mobility network and that both are isomorphic except for a higher spatial decay coefficient of the mobility network relative to the call-based network: when we discount distance effects on the call connections with the same decay observed for mobility connections, the two networks are virtually indistinguishable.

    The Albert Einstein College of Medicine (Einstein) was founded in 1955 during an era of limited access to medical school for women, racial minorities, and many religious and ethnic groups. Located in the Bronx, NY, Einstein seeks to educate physicians in an environment of state-of-the-art scientific inquiry while simultaneously fulfilling a deep commitment to serve its community by providing the highest quality clinical care. A founding principle of Einstein, the basis upon which Professor Einstein agreed to allow the use of his name, was that admission to the student body would be based entirely on merit. To accomplish this, Einstein has long used a 'holistic' approach to the evaluation of its applicants, actively seeking a diverse student body. More recently, in order to improve its ability to identify students with the potential to be outstanding physicians, who will both advance medical knowledge and serve the pressing health needs of a diverse community, the Committee on Admissions reexamined and restructured the requirements for admission. These have now been categorized as four 'Admissions Competencies' that an applicant must demonstrate. They include: 1) cocurricular activities and relevant experiences; 2) communication skills; 3) personal and professional development; and 4) knowledge. The purpose of this article is to describe the process that resulted in the introduction and implementation of this competency based approach to the admission process.

    Multi-service aggregated transmission is the direction of IP network. Providing different Quality of Service (QoS) assurance for different services has become a crucial problem in future network.Admission control is a vital function for multi-service IP network. This paper proposes a novel fuzzy admission control scheme based on coarse granularity service-aware technique. Different service has discriminative sensitivity to the same QoS characteristic parameter in general. The traffic class can be perceived by the service request parameter and the proposed QoS function. And requirements of different applications can be met by maintaining the life parameter. From simulation results, the proposed scheme shows a better QoS provisioning than those traditional fuzzy logic based methods under the same admission probability.

    2011-05-01

    Full Text Available Abstract Background Nursing home residents are prone to acute illness due to their high age, underlying illnesses and immobility. We examined the incidence of acute hospital admissions among nursing home residents versus the age-matched community dwelling population in a geographically defined area during a two years period. The hospital stays of the nursing home population are described according to diagnosis, length of stay and mortality. Similar studies have previously not been reported in Scandinavia. Methods The acute hospitalisations of the nursing home residents were identified through ambulance records. These were linked to hospital patient records for inclusion of demographics, diagnosis at discharge, length of stay and mortality. Incidence of hospitalisation was calculated based on patient-time at risk. Results The annual hospital admission incidence was 0.62 admissions per person-year among the nursing home residents and 0.26 among the community dwellers. In the nursing home population we found that dominant diagnoses were respiratory diseases, falls-related and circulatory diseases, accounting for 55% of the cases. The median length of stay was 3 days (interquartile range = 4. The in-hospital mortality rate was 16% and 30 day mortality after discharge 30%. Conclusion Acute hospital admission rate among nursing home residents was high in this Scandinavian setting. The pattern of diagnoses causing the admissions appears to be consistent with previous research. The in-hospital and 30 day mortality rates are high.

    We used fixed-effect models to examine the relationship between local spending on home- and community-based services (HCBSs) for cash-assisted Medicaid-only disabled (CAMOD) adults and younger adult admissions to nursing homes in the United States during 2001 through 2008, with control for facility and market characteristics and secular trends. We found that increased CAMOD Medicaid HCBS spending at the local level is associated with decreased admissions of younger adults to nursing homes. Our findings suggest that states' efforts to expand HCBS for this population should continue.

    2008-01-01

    A novel method for detecting anomalous program behavior is presented, which is applicable to hostbased intrusion detection systems that monitor system call activities. The method constructs a homogeneous Markov chain model to characterize the normal behavior of a privileged program, and associates the states of the Markov chain with the unique system calls in the training data. At the detection stage, the probabilities that the Markov chain model supports the system call sequences generated by the program are computed. A low probability indicates an anomalous sequence that may result from intrusive activities. Then a decision rule based on the number of anomalous sequences in a locality frame is adopted to classify the program's behavior. The method gives attention to both computational efficiency and detection accuracy, and is especially suitable for on-line detection. It has been applied to practical host-based intrusion detection systems.

    2003-01-01

    Measurement-Based Admission Control (MBAC) algorithms, as opposed to the more conservative worstcase parameter-based approach, are expressly designed to achieve high levels of network utilization for the controlledload service, a real-time service with very relaxed service guarantee. Most researchers studying MBAC algorithms(MBAC's) have focused primarily on the design of the Admission Control Equations (ACE's) using a variety of principled and ad hoc motivations. In this paper, we prove theoretically that the ACE's, even though derived and motivated in quite different ways, are equivalent by tuning the adjustable parameters of MBAC's. We also use simulations to confirm our work. The simulation results show that MBAC's may have the same utilization for a given packet loss rate through tuning the relevant parameters.

    2009-01-01

    The advantages of tabled evaluation regarding program termination and reduction of complexity are well known --as are the significant implementation, portability, and maintenance efforts that some proposals (especially those based on suspension) require. This implementation effort is reduced by program transformation-based continuation call techniques, at some efficiency cost. However, the traditional formulation of this proposal by Ramesh and Cheng limits the interleaving of tabled and non-tabled predicates and thus cannot be used as-is for arbitrary programs. In this paper we present a complete translation for the continuation call technique which, using the runtime support needed for the traditional proposal, solves these problems and makes it possible to execute arbitrary tabled programs. We present performance results which show that CCall offers a useful tradeoff that can be competitive with state-of-the-art implementations.

    Wu Naixing; Liao Jianxin; Zhu Xiaomin

    2006-01-01

    Based on the demand of the admission control of softswitch-based clustered media server, this paper proposed a new dynamic quota-based admission control algorithm that has a sub-negotiation process. The strongpoint of quota-based algorithm had been inherited in the algorithm and at the same time some new ideas had also been introduced into it. Simulations of the algorithm had been conducted on the Petri net model and the results show that this algorithm has excellent performance. In order to find the optimal resource quota setting in real time, the paper proposed two approximation analysis methods. It can be seen from analysis results that these two methods can be used to get sub-optimal quota values quickly and effectively. These two approximation analysis methods will play important roles in implementation of the algorithm in system.

    Full Text Available In IEEE 802.16 systems, the algorithm of admission control (AC is very important in guaranteeing the Quality of Service (QoS and managing service flows. However, the IEEE 802.16 standards do not specify any related strategies or algorithms on AC. In order to improve the system performance and satisfy the QoS of stations to the max, we propose a new AC strategy, which includes a weighted blocking rate based priority strategy and a satisfaction-degree based bandwidth-borrowing strategy named SDB in this paper. The simulation results show that the proposed strategy improves the overall performance of system in terms of weighted blocking rate. Furthermore, our strategy enhances the QoS in comparison with the strategy adopting conventional bandwidth-borrowing algorithm.

    Booth, R; 10.1613/jair.1874

    2011-01-01

    As partial justification of their framework for iterated belief revision Darwiche and Pearl convincingly argued against Boutiliers natural revision and provided a prototypical revision operator that fits into their scheme. We show that the Darwiche-Pearl arguments lead naturally to the acceptance of a smaller class of operators which we refer to as admissible. Admissible revision ensures that the penultimate input is not ignored completely, thereby eliminating natural revision, but includes the Darwiche-Pearl operator, Nayaks lexicographic revision operator, and a newly introduced operator called restrained revision. We demonstrate that restrained revision is the most conservative of admissible revision operators, effecting as few changes as possible, while lexicographic revision is the least conservative, and point out that restrained revision can also be viewed as a composite operator, consisting of natural revision preceded by an application of a "backwards revision" operator previously studied by Papini. ...

    In order to better accommodate heterogeneous quality of service (QoS) in wireless networks, an algorithm called QeS-aware power and admission controls (QAPAC) is proposed. The system is modeled as u non- cooperative game where the users adjust their transmit powers to maximize the utility, thus restraining the interferences. By using adaptive utility functions and tunable pricing parameters according to QoS levels, this algorithm can well meet different QoS reqniremcnts and improve system capacity compared with those that ignore the QoS differ- ences.

    Full Text Available A significant percentage of students who attend secondary schools in the United States do not acquire the basic writing skills required to gain admission to four-year colleges and universities. In the present study, participants were 41 low-income, multi-ethnic 12th-grade students, 19 of whom received instruction on specific genre features for writing college admission essays. The other 22 12th-grade students formed the comparison group and received instruction as usual in their regular English class (mostly on literary analysis. The students who received instruction on genre features of the college admission essay scored higher on a rubric-based rating of the pre and post test essay writing and on writing self-efficacy surveys associated with the genre. Findings yielded from this study point to the merit of using a features-based genre instructional approach to teaching college admission essays to low-income, multi-ethnic high school students.

  5. Study on the Class-Based Admission Control Scheme for DiffServ in MPLS Networks

    Institute of Scientific and Technical Information of China (English)

    李震宇; 张中兆

    2003-01-01

    Differentiated services (DiffServ) and MPLS are two major building blocks for providing multi-class services over IP networks. In order to respond to the need for relatively simple, coarse methods of providing different levels of service for Internet traffic, to support various types of applications and specific business requirements, the MPLS network infrastructure and the DiffServ traffic model will work together. Meanwhile, in today's environment of multiple service networks, it is necessary for the node in the networks to perform the control mechanism to guarantee various QoS. In this paper, we propose a class-based admission control scheme that is suitable for DiffServ in MPLS networks. This scheme can achieve twofold objects: reliable QoS provisioning and high resource utilization. We evaluate the proposed scheme by numerical analysis of its performance in terms of throughput, delay, and reject probability. By performing simulation, we can ensure that the proposed scheme can work efficiently to provide strict QoS guarantees.

    Full Text Available OBJECTIVE: Children with Down syndrome, the most common genetic cause of intellectual disability, are prone to multiple and varied health-related problems. This study describes patterns of hospitalisations for children and young people with Down syndrome in Western Australia. METHODS: Birth records were linked to the Western Australian population-based Intellectual Disability database to identify all children born with Down syndrome in Western Australia between 1 January, 1983 and 31 December, 1999. These records were linked to the Hospital Morbidity Data System to provide information on all hospitalisations up to 31 December, 2004. Hospitalisation data, coded using ICD-9CM or ICD-10 (v0.5 were grouped into clinically relevant categories using the primary diagnosis. Rates of hospital admission for all and specific diagnoses were expressed in 1000-person-years at-risk and median age at first admission and length of stay were calculated. RESULTS: Of the 405 children, 395 had one or more hospital admissions, totalling 3786 admissions for all children and an estimated 39.5 person-years in hospital. On average, children were admitted 9.7 times, with an estimated rate of 757.2 admissions per 1000pyr (95% CI: 680, 843. A quarter of all admissions occurred in the first year of life. The average hospital length of stay was 3.8 days (95% CI: 3.7, 4.1. Upper respiratory tract conditions affected the most children (58.5% and accounted for 12.1% of all admissions. Other disorders which affected a high percentage of children were ear/hearing conditions (50.6%, disorders of the oral cavity (38.0% and lower respiratory tract conditions (37.5%. Overall, children with Down syndrome were hospitalised at a rate five times (95% CI = 4.3-6.2 that of the general population. CONCLUSION: Children with Down syndrome are at increased risk of morbidity for varied causes underlining the importance of comprehensive and targeted primary care for this group.

    GUIZhibo; ZHOULichao

    2005-01-01

    The advantage of Measurement-based admission control algorithms (MBACs) is that they are able to improve network utilization for the controlled-load service. Most researchers have focused primarily on designs of the Admission control equations (ACEs) of MBACs using a variety of principled and ad hoc motivations. In this paper, six typical MBACs, namely MS, HB, TP, TO, TE and MC algorithms, are discussed. First, we have proven analytically that the ACEs of TE and MC have the same structural form as the ACEs of the other four MBACs above. Second, through formal analysis we have theoretically proven that the ACEs of TE and MC, even though they are derived and motivated in quite different ways, are equivalent to the other four MBACs by tuning the adjustable parameters of MBACs. Finally, we have used also simulations to confirm our work.

    This paper proposes a reinforcement learning-based lexicographic approach to the call admission control problem in communication networks. The admission control problem is modelled as a multi-constrained Markov decision process. To overcome the problems of the standard approaches to the solution of constrained Markov decision processes, based on the linear programming formulation or on a Lagrangian approach, a multi-constraint lexicographic approach is defined, and an online implementation based on reinforcement learning techniques is proposed. Simulations validate the proposed approach.

    Full Text Available The main purpose of this descriptive research is to provide a CALL (Computer-Assisted Language Learning-based lesson plan for teaching reading comprehension to Iranian intermediate EFL learners. CALL is a new way of learning and teaching language. It is proved that CALL mainly has positive effects on educational contexts. Although teachers believe that CALL will have positive effect in the process of learning a language, they prefer the traditional methods. The reason is that they do not have a guide to work based on it. As a result, this study tries to design a CALL-based lesson plan to suggest not only the teachers, but also the students to examine the benefits of the method.

  18. A Cross-Entropy-Based Admission Control Optimization Approach for Heterogeneous Virtual Machine Placement in Public Clouds

    Directory of Open Access Journals (Sweden)

    2016-03-01

    Full Text Available Virtualization technologies make it possible for cloud providers to consolidate multiple IaaS provisions into a single server in the form of virtual machines (VMs. Additionally, in order to fulfill the divergent service requirements from multiple users, a cloud provider needs to offer several types of VM instances, which are associated with varying configurations and performance, as well as different prices. In such a heterogeneous virtual machine placement process, one significant problem faced by a cloud provider is how to optimally accept and place multiple VM service requests into its cloud data centers to achieve revenue maximization. To address this issue, in this paper, we first formulate such a revenue maximization problem during VM admission control as a multiple-dimensional knapsack problem, which is known to be NP-hard to solve. Then, we propose to use a cross-entropy-based optimization approach to address this revenue maximization problem, by obtaining a near-optimal eligible set for the provider to accept into its data centers, from the waiting VM service requests in the system. Finally, through extensive experiments and measurements in a simulated environment with the settings of VM instance classes derived from real-world cloud systems, we show that our proposed cross-entropy-based admission control optimization algorithm is efficient and effective in maximizing cloud providers’ revenue in a public cloud computing environment.

The research findings indicate that technology based CRM significantly a ffects first call resolution and perceived service quality, but weakly influence caller satisfactions through the mediating role of firs t call resolutions. Observably, this research believes that customer contact centers as the first touch points to company are dependent on other factors such as company policy, product quality, customer characteristics, etc. to influence caller sati sfactions, but unfortunately most of these factors fall outside the operational control of cont act center activities. The findings in this research has empirically provided the long waiting evidence that technology based CRM applications within the inbound contact center industry can only influence caller satisfactions through first call resolution and perceived service quality. A major implication for call center managers is that this research findings has availed them the opportunity on how to effectively develop, implement, and evaluate their CRM applications.

    The direct sequencing of PCR products generates heterozygous base-calling fluorescence chromatograms that are useful for identifying single-nucleotide polymorphisms (SNPs), insertion-deletions (indels), short tandem repeats (STRs), and paralogous genes. Indels and STRs can be easily detected using the currently available Indelligent or ShiftDetector programs, which do not search reference sequences. However, the detection of other genomic variants remains a challenge due to the lack of appropriate tools for heterozygous base-calling fluorescence chromatogram data analysis. In this study, we developed a free web-based program, Mixed Sequence Reader (MSR), which can directly analyze heterozygous base-calling fluorescence chromatogram data in .abi file format using comparisons with reference sequences. The heterozygous sequences are identified as two distinct sequences and aligned with reference sequences. Our results showed that MSR may be used to (i) physically locate indel and STR sequences and determine STR copy number by searching NCBI reference sequences; (ii) predict combinations of microsatellite patterns using the Federal Bureau of Investigation Combined DNA Index System (CODIS); (iii) determine human papilloma virus (HPV) genotypes by searching current viral databases in cases of double infections; (iv) estimate the copy number of paralogous genes, such as β-defensin 4 (DEFB4) and its paralog HSPDP3.

With an aim of evaluating role of admission test in predicting the adverse fetal outcome in high risk pregnancies in Government Chengalpattu Medical College, a cross-sectional study was designed including 50 high risk patients and 50 low risk patients. All the patients were subjected to a standard clinical evaluation using a proforma and subsequently subjected to admission test for 20 mins and their readings were grouped into 1. Reactive, 2. Suspicious, 3. Ominous. Intervention is planned based on the tracings of the admission test. The data from the admission test were compiled and subjected to statistical analysis. At the end of statistical analysis, it is found that electronic fetal monitoring has high sensitivity and low specificity. Antepartum risk factors are a poor predictors of fetal outcome. A normal tracing carries a predictive value of over 95% for APGAR score of 7 or greater and an abnormal tracing carries a predictive value of about 50% for APGAR score less than 7. In high risk cases admission test is more sensitive and in low risk cases the admission test is more specific. The negative predictive value for both groups were 85.2% and 97.7%

  14. A three-parameter model for classifying anurans into four genera based on advertisement calls.

    Science.gov (United States)

    Gingras, Bruno; Fitch, William Tecumseh

    2013-01-01

    The vocalizations of anurans are innate in structure and may therefore contain indicators of phylogenetic history. Thus, advertisement calls of species which are more closely related phylogenetically are predicted to be more similar than those of distant species. This hypothesis was evaluated by comparing several widely used machine-learning algorithms. Recordings of advertisement calls from 142 species belonging to four genera were analyzed. A logistic regression model, using mean values for dominant frequency, coefficient of variation of root-mean square energy, and spectral flux, correctly classified advertisement calls with regard to genus with an accuracy above 70%. Similar accuracy rates were obtained using these parameters with a support vector machine model, a K-nearest neighbor algorithm, and a multivariate Gaussian distribution classifier, whereas a Gaussian mixture model performed slightly worse. In contrast, models based on mel-frequency cepstral coefficients did not fare as well. Comparable accuracy levels were obtained on out-of-sample recordings from 52 of the 142 original species. The results suggest that a combination of low-level acoustic attributes is sufficient to discriminate efficiently between the vocalizations of these four genera, thus supporting the initial premise and validating the use of high-throughput algorithms on animal vocalizations to evaluate phylogenetic hypotheses.

    Since the quick topology change and short connection duration, the VANET has had unstable routing and wireless signal quality. This paper proposes a kind of lightweight routing protocol-LNIB for call system without base station, which is applicable to the urban taxis. LNIB maintains and predicts neighbor information dynamically, thus finding the reliable path between the source and the target. This paper describes the protocol in detail and evaluates the performance of this protocol by simulating under different nodes density and speed. The result of evaluation shows that the performance of LNIB is better than AODV which is a classic protocol in taxi-call scene. PMID:24737984

    2015-01-01

    Spatio-temporal interaction is inherent to cases of infectious diseases and occurrences of earthquakes, whereas the spread of other events, such as cancer or crime, is less evident. Statistical significance tests of space-time clustering usually assess the correlation between the spatial and temporal (transformed) distances of the events. Although appealing through simplicity, these classical tests do not adjust for the underlying population nor can they account for a distance decay of interaction. We propose to use the framework of an endemic-epidemic point process model to jointly estimate a background event rate explained by seasonal and areal characteristics, as well as a superposed epidemic component representing the hypothesis of interest. We illustrate this new model-based test for space-time interaction by analysing psychiatric inpatient admissions in Zurich, Switzerland (2007-2012). Several socio-economic factors were found to be associated with the admission rate, but there was no evidence of genera...

    Allen's big-eared bat (Idionycteris phyllotis) inhabits much of the southwestern USA, but has not been documented in Colorado. We recorded echolocation calls consistent with I. phyllotis near La Sal Creek, Montrose County, Colorado. Based on characteristics of echolocation calls and flight behavior, we conclude that the echolocation calls described here were emitted by I. phyllotis and that they represent the first documentation of this species in Colorado.

  19. Analysis of Completion of Call with on-off Data Source in Wireless Networks

    XUAN Xiao-ying; SHI Bing-xin; ZOU Ling

    2004-01-01

    In wireless network, call completion probability accounts for users' satisfaction since the admitted ongoing call may be interrupted during hand-off process or even stay in the same cell when dynamically allocating resource to calls because of the loss of resource. We focus on the relationship between call's completion probability and these interruptions and develop an analytical relationship model for homogeneous cellular networks based on probability analysis. Then assuming call's data source is modeled by on-off traffic model, a two dimensional Markov process is established to compute these blocking and dropping probabilities for call's completion probability. The impacts of different new call arrival rate, call's traffic characteristic, user's mobility, call's holding time and call's admission threshold on call's completion are evaluated and compared through numerical examples. These results show that call's completion reaches its maximum value if making no difference between hand-off call and new call in the case of light traffic load. But some resource should be reserved for the hand-off call in high traffic scenario. The analytical model provides a basis for helping to set the call admission threshold.

    2007-08-01

    This paper considers the problem of detection of contact calls produced by the critically endangered North Atlantic right whale, Eubalaena glacialis. To reduce computational time, the class of acceptable detectors is constrained by the detectors implemented as a bank of two-dimensional linear FIR filters and using the data spectrogram as the input. The closed form representations for the detectors are derived and the detection performance is compared with that of the generalized likelihood ratio test (GLRT) detector. The test results demonstrate that in the presence of impulsive noise, the spectrogram-based detector using the French hat wavelet as the filter kernel outperforms the GLRT detector and decreases computational time by a factor of 6.

In contrast, a single escape strategy appears to be sufficient in less-structured open habitats, and under such conditions urgency-dependent alarm calls may be favored. Nevertheless, some species, such as meerkats (Suricata suricatta), have evolved functionally referential alarm calls despite living in open areas, using only bolt-holes for retreat. To understand the evolution of different alarm call systems, we investigated the calls of sympatric Cape ground squirrels (Xerus inauris) and compared their antipredator and foraging behavior with that of meerkats. Cape ground squirrels emitted urgency-dependent alarm calls and responded to playbacks depending on urgency, not predator type. Vigilance behavior and habitat use differed between the two species. Meerkats roam widely to find prey and for efficient foraging depend on coordinated predator vigilance and escape behavior. As herbivores with smaller territories, Cape ground squirrels depend less on coordinated antipredator behavior, and urgency-dependent alarm calls encode all essential information. We conclude that habitat complexity does not explain the evolution of functionally referential alarm calls in all species, and other constraints, such as the need to coordinate group movements to maintain foraging efficiency, could be more relevant.

    Effective self-management and treatment compliance is important in achieving good symptom control in asthma. The aim of this study was to determine whether asthma nurse intervention during hospital admission could increase knowledge and improve self-management and whether this would influence the number of emergency call-out visits by Genera Practitioners (GPs) and hospital re-admissions. Patients with acute asthma (n=80) were assessed by the asthma nurse within 24 h of admission using a British Thoracic Society (BTS) guideline-based questionnaire. Main outcome measures were: know edge of inhalers, self-management plans, peak flow monitoring, recognition of worsening symptoms and appropriate emergency action, Following randomization, half received nurse intervention during hospitalization. All received a follow-up questionnaire 6 weeks post-discharge and again at 6 months (response rates 86% and 81% respectively). GPs were contacted by postal questionnaire after 4 months. Questionnaire responses indicated an increase in knowledge in the intervention group, along with an ability to identify appropriate action on worsening symptoms. Emergency GP call-outs were more frequent in the control group in the 4 months post-discharge. Hospital re-admission rates were similar in both groups. Asthma nurse intervention appeared to increase knowledge of asthma management, maintained throughout the study period, but had no significant impact on reducing re-admissions to hospital.

    Full Text Available Background: Organophosphate compound (OPC poisoning is common in the developing countries such as India. The acute and later effects of OPC poisoning on pituitary and target gland hormones is largely unknown. Materials and Methods: This prospective study was conducted at Postgraduate Institute of Medical Education and Research between January 2012 and March 2013. Fourteen patients (8 males, age 18-50 years with acute OPC poisoning were included in the study based on the history and clinical features, documented decreased in plasma cholinesterase activity or presence of the OPC in gastric lavage/blood samples. The hormonal parameters were done at baseline, at the time of discharge and at three months of follow-up. Results: A total of 14 patients out of 46 with the mean age of 30.1 ± 10.3 years were finally eligible for the study. Hormonal alterations at admission were similar to sick euhormonal syndrome. Overall 7 of them had nine hormonal deficits at three months of follow up, 4 having sub normal basal cortisol level and two each had low testosterone and growth hormone and only one had thyroxine deficiency. Conclusion: Acute organophosphate poisoning results in endocrine dysfunction akin to sick euhormonal syndrome. However, in a small subset of patients, varying level of hormonal insufficiency may occur either at admission or later. These observations need re-validation in a larger group of patients with specific OPC.

    Full Text Available The aim of this study was to develop a brief daily hassle diagnostic questionnaire that could be used to identify daily hassles for customer service representatives within a call centre environment, and to investigate the relationship between daily hassles and burnout. A crosssectional survey was used with an accidental sample (N = 394 taken from a service and sales call centre. An exploratory factor analysis of the data resulted in a six-factor model of daily hassles consisting of daily demands, continuous change, co-worker hassles, demotivating work environment, transportation hassles and personal concerns. The internal consistency of one factor, namely personal concerns, was low. Exhaustion was best predicted by four categories of daily hassles, namely daily demands, continuous change, a demotivating work environment, and transportation hassles.

  15. Distributed Graph Coloring: An Approach Based on the Calling Behavior of Japanese Tree Frogs

    CERN Document Server

    Hernández, Hugo

    2010-01-01

    Graph coloring, also known as vertex coloring, considers the problem of assigning colors to the nodes of a graph such that adjacent nodes do not share the same color. The optimization version of the problem concerns the minimization of the number of used colors. In this paper we deal with the problem of finding valid colorings of graphs in a distributed way, that is, by means of an algorithm that only uses local information for deciding the color of the nodes. Such algorithms prescind from any central control. Due to the fact that quite a few practical applications require to find colorings in a distributed way, the interest in distributed algorithms for graph coloring has been growing during the last decade. As an example consider wireless ad-hoc and sensor networks, where tasks such as the assignment of frequencies or the assignment of TDMA slots are strongly related to graph coloring. The algorithm proposed in this paper is inspired by the calling behavior of Japanese tree frogs. Male frogs use their calls...

    2013-01-01

    Full Text Available Software as a Service (SaaS offers reliable access to software applications to the end users over the Internet without direct investment in infrastructure and software. SaaS providers utilize resources of internal data centres or rent resources from a public Infrastructure as a Service (IaaS provider in order to serve their customers. Internal hosting can ample cost of administration and maintenance whereas hiring from an IaaS provider can impact the service quality due to its variable performance. To surmount these drawbacks, we propose pioneering admission control and scheduling algorithms for SaaS providers to effectively utilize public Cloud resources to maximize profit by minimizing cost and improving customer satisfaction level. There is a drawback in this method is strength of the algorithms by handling errors in dynamic scenario of cloud environment, also there is a need of machine learning method to predict the strategies and produce the according resources. The admission control provided by trust model that is based on SLA uses different strategies to decide upon accepting user requests so that there is minimal performance impact, avoiding SLA penalties that are giving higher profit. Machine learning method aims at building a distributed system for cloud resource monitoring and prediction that includes learning-based methodologies for modelling and optimization of resource prediction models. The learning methods are Artificial Neural Network (ANN and Support Vector Machine (SVM are two typical machine learning strategies in the category of regression computation. These two methods can be employed for modelling resource state prediction. In addition, we conduct a widespread evaluation study to analyze which solution matches best in which scenario to maximize SaaS provider’s profit. Results obtained through our extensive simulation shows that our proposed algorithms provide significant improvement (up to 40% cost saving over

    Home-based clinical informatics technologies are being developed to facilitate health care provision and management. Given the novelty of these technologies, end users such as patients and their formal and informal caregivers may require support during use. This paper presents a case study within the United States of the service desk calls generated over a 31-month period by patients enrolled in a large randomized field experiment, HeartCare II. This case study provides future deployers of home-based clinical information technologies with an understanding of the types of support that may be required during use. Our analysis reveals that calls to the service desk originated as a result of user problems, hardware problems, software problems, and internal communication problems among individuals involved in the delivery and use of the technology. Implications of these needs for support during use are also discussed. PMID:24199135

  4. Neutron spectrometry and dosimetry based on a new approach called Genetic Artificial Neural Networks

    International Nuclear Information System (INIS)

    Artificial Neural Networks and Genetic Algorithms are two relatively young research areas that were subject to a steadily growing interest during the past years. The structure of a neural network is a significant contributing factor to its performance and the structure is generally heuristically chosen. The use of evolutionary algorithms as search techniques has allowed different properties of neural networks to be evolved. This paper focuses on the intersection on neural networks and evolutionary computation, namely on how evolutionary algorithms can be used to assist neural network design and training, as a novel approach. In this research, a new evolvable artificial neural network modelling approach is presented, which utilizes an optimization process based on the combination of genetic algorithms and artificial neural networks, and is applied in the design of a neural network, oriented to solve the neutron spectrometry and simultaneous dosimetry problems, using only the count rates measured with a Bonner spheres spectrometer system as entrance data.

    Introduction: The underrepresentation of students from lower socioeconomic backgrounds in medical education is an important social issue. There is currently little evidence about whether changes in admission strategy could increase the diversity of medical students. Denmark introduced an “attribute......-based” admission track to make it easier for students who may not be eligible for admission through the “grade-based” track, to be admitted on the basis of attributes other than academic performance. The aim of this research was to examine whether there were significant differences in the social composition...... of students admitted via the two tracks between the years 2002-2007. Method: This prospective cohort study included 1074 medical students admitted between the years 2002-2007 to the University of Southern Denmark (USD) medical school. Of these, 454 were admitted by grade-based selection and 620 were selected...

  7. Cfd Based Shape Optimization of Ic Engine Optimisation de l'admission et des chambres de combustion des moteurs avec la modélisation 3D

    Directory of Open Access Journals (Sweden)

    Griaznov V.

    2006-12-01

    Full Text Available Intense competition and global regulations in the automotive industry has placed unprecedented demands on the performance, efficiency, and emissions of today's IC engines. The success or failure of a new engine design to meet these often-conflicting requirements is primarily dictated by its capability to provide minimal restriction for the inducted and exhausted flow and by its capability to generate strong large-scale in-cylinder motion. The first criterion is directly linked to power performance of the engine, while the latter has been shown to control the burn rate in IC engines. Enhanced burn rates are favorable to engine efficiency and partial load performance. CFD based numerical simulations have recently made it possible to study the development of such engine flows in great details. However, they offer little guidance for modifying the ports and chamber geometry controlling the flow to meet the desired performance. This paper presents a methodology which combines 3D, steady state CFD techniques with robust numerical optimization tools to design, rather than just evaluate the performance, of IC engine ports and chambers. La forte concurrence et les réglementations dans l'industrie automobile entraînent aujourd'hui une exigence sans précédent de performance, de rendement et d'émissions pour les moteurs à combustion interne. Le succès ou l'échec de la conception d'un nouveau moteur satisfaisant à ces propriétés, souvent contradictoires, est dicté, dans un premier temps, par l'obtention d'une restriction minimale des débits d'admission et d'échappement, ensuite, par la nécessité de générer des écoulements forts de grande amplitude. Le premier critère est directement lié à la performance du moteur, tandis que le second est reconnu comme contrôlant la combustion. Des dégagements de chaleur accélérés améliorent le rendement et les performances à faible charge. La simulation 3D rend possible depuis peu d

    2011-01-01

    A VoIP based call has stringent QoS requirements with respect to delay, jitter, loss, MOS and R-Factor. Various QoS mechanisms implemented to satisfy these requirements must be adaptive under diverse network scenarios and applied in proper sequence, otherwise they may conflict with each other. The objective of this paper is to address the problem of adaptive QoS maintenance and sequential execution of available QoS implementation mechanisms with respect to VoIP under varying network conditions. In this paper, we generalize this problem as state-space problem and solve it. Firstly, we map the problem of QoS optimization into state-space domain and apply incremental heuristic search. We implement the proposed algorithm under various network and user scenarios in a VoIP test-bed for QoS enhancement. Then learning strategy is implemented for refinement of knowledge base to improve the performance of call quality over time. Finally, we discuss the advantages and uniqueness of our approach.

  15. FamSeq: a variant calling program for family-based sequencing data using graphics processing units.

    Full Text Available Various algorithms have been developed for variant calling using next-generation sequencing data, and various methods have been applied to reduce the associated false positive and false negative rates. Few variant calling programs, however, utilize the pedigree information when the family-based sequencing data are available. Here, we present a program, FamSeq, which reduces both false positive and false negative rates by incorporating the pedigree information from the Mendelian genetic model into variant calling. To accommodate variations in data complexity, FamSeq consists of four distinct implementations of the Mendelian genetic model: the Bayesian network algorithm, a graphics processing unit version of the Bayesian network algorithm, the Elston-Stewart algorithm and the Markov chain Monte Carlo algorithm. To make the software efficient and applicable to large families, we parallelized the Bayesian network algorithm that copes with pedigrees with inbreeding loops without losing calculation precision on an NVIDIA graphics processing unit. In order to compare the difference in the four methods, we applied FamSeq to pedigree sequencing data with family sizes that varied from 7 to 12. When there is no inbreeding loop in the pedigree, the Elston-Stewart algorithm gives analytical results in a short time. If there are inbreeding loops in the pedigree, we recommend the Bayesian network method, which provides exact answers. To improve the computing speed of the Bayesian network method, we parallelized the computation on a graphics processing unit. This allowed the Bayesian network method to process the whole genome sequencing data of a family of 12 individuals within two days, which was a 10-fold time reduction compared to the time required for this computation on a central processing unit.

  16. Characteristics of the 14 April 1999 Sydney hailstorm based on ground observations, weather radar, insurance data and emergency calls

    Full Text Available Hailstorms occur frequently in metropolitan Sydney, in the eastern Australian State of New South Wales, which is especially vulnerable due to its building exposure and geographical location. Hailstorms challenge disaster response agencies and pose a great risk for insurance companies. This study focuses on the Sydney hailstorm of 14 April 1999 – Australia's most expensive insured natural disaster, with supporting information from two other storms. Comparisons are drawn between observed hailstone sizes, radar-derived reflectivity and damage data in the form of insurance claims and emergency calls. The 'emergency response intensity' (defined by the number of emergency calls as a proportion of the total number of dwellings in a Census Collection District is a useful new measure of the storm intensity or severity experienced. The area defined by a radar reflectivity ≥55 dBZ appears to be a good approximation of the damage swath on ground. A preferred area for hail damage is located to the left side of storm paths and corresponds well with larger hailstone sizes. Merging hail cells appear to cause a substantially higher emergency response intensity, which also corresponds well to maximum hailstone sizes. A damage threshold could be identified for hailstone sizes around 2.5 cm (1 cm, based on the emergency response intensity (insurance claims. Emergency response intensity and claims costs both correlate positively with hailstone sizes. Higher claim costs also occurred in areas that experienced higher emergency response intensities.

    2011-11-01

    Full Text Available Abstract Background Cutting and piercing injuries are among the leading causes of unintentional injury morbidity in developed countries. In New Zealand, cutting and piercing are second only to falls as the most frequent cause of unintentional home injuries resulting in admissions to hospital among people aged 20 to 64 years. Alcohol intake is known to be associated with many other types of injury. We used a case-crossover study to investigate the role of acute alcohol use (i.e., drinking during the previous 6 h in unintentional cutting or piercing injuries at home. Methods A population-based case-crossover study was conducted. We identified all people aged 20 to 64 years, resident in one of three regions of the country (Greater Auckland, Waikato and Otago, who were admitted to public hospital within 48 h of an unintentional non-occupational cutting or piercing injury sustained at home (theirs or another's from August 2008 to December 2009. The main exposure of interest was use of alcohol in the 6-hour period before the injury occurred and the corresponding time intervals 24 h before, and 1 week before, the injury. Other information was collected on known and potential confounders. Information was obtained during face-to-face interviews with cases, and through review of their medical charts. Results Of the 356 participants, 71% were male, and a third sustained injuries from contact with glass. After adjustment for other paired exposures, the odds ratio for injury after consuming 1 to 3 standard drinks of alcohol during the 6-hour period before the injury (compared to the day before, compared to none, was 1.77 (95% confidence interval 0.84 to 3.74, and for four or more drinks was 8.68 (95% confidence interval 3.11 to 24.3. Smokers had higher alcohol-related risks than non-smokers. Conclusions Alcohol consumption increases the odds of unintentional cutting or piercing injury occurring at home and this risk increases with higher levels of drinking.

  6. Acoustic mechanisms of a species-based discrimination of the chick-a-dee call in sympatric black-capped (Poecile atricapillus and mountain chickadees (P. gambeli

    Directory of Open Access Journals (Sweden)

    Lauren M Guillette

    2010-12-01

    Full Text Available Previous perceptual research with black-capped and mountain chickadees has demonstrated that these species treat each other’s namesake chick-a-dee calls as belonging to separate, open-ended categories. Further, the terminal dee portion of the call has been implicated as the most prominent species marker. However, statistical classification using acoustic summary features suggests that all note-types contained within the chick-a-dee call should be sufficient for species classification. The current study seeks to better understand the note-type based mechanisms underlying species-based classification of the chick-a-dee call by black-capped and mountain chickadees. In two, complimentary, operant discrimination experiments, both species were trained to discriminate the species of the signaller using either entire chick-a-dee calls, or individual note-types from chick-a-dee calls. In agreement with previous perceptual work we find that the D note had significant stimulus control over species based discrimination. However, in line with statistical classifications, we find that all note-types carry species information. We discuss reasons why the most easily discriminated note-types are likely candidates to carry species based cues.

    2007-01-01

    In this paper we propose a scalable admission control scheme for the QoS sensitivity traffic in DiffServ domains. In our scheme, the ingress routers perform admissibility test in a fully distributed and parallel fashion for requests based on our resource per-assigning mechanism.Then, we introduce a novel two phase token passing mechanism to adaptively optimize resource per-assigning among contending edge ronters in proportion to their traffic.In addition, we adopt a measurement based admission decision-making criterion to gain the benefit of high utilization of statistical multiplexing. Our simulation results indicate that even under very high request load it is possible to perform admission control and resource allocation in parallel without suffering in terms of response time, packet loss rate, or utilization.

    2015-12-01

    Clinical home visit programs for Medicare beneficiaries are a promising approach to supporting aging in place and avoiding high-cost institutional care. Such programs combine a comprehensive geriatric assessment by a clinician during a home visit with referrals to community providers and health plan resources to address uncovered issues. We evaluated UnitedHealth Group's HouseCalls program, which has been offered to Medicare Advantage plan members in Arkansas, Georgia, Missouri, South Carolina, and Texas since January 2008. We found that, compared to non-HouseCalls Medicare Advantage plan members and fee-for-service beneficiaries, HouseCalls participants had reductions in admissions to hospitals (1 percent and 14 percent, respectively) and lower risk of nursing home admission (0.67 percent and 1.3 percent, respectively). In addition, participants' numbers of office visits--chiefly to specialists--increased 2-6 percent (depending on the comparison group). The program's effects on emergency department use were mixed. These results indicate that a thorough home-based clinical assessment of a member's health and home environment combined with referral services can support aging in place, promote physician office visits, and preempt costly institutional care.

  9. Development and evaluation of a hand held computer based on-call pack for health protection out of hours duty: A pilot study

    Directory of Open Access Journals (Sweden)

    Williams Christopher J

    2005-04-01

    Full Text Available Abstract Background The on call service for health protection in most parts of the UK is provided by general public health consultants, registrars and nurses as the first tier of response backed up by medical consultants in health protection. The first tier responder usually carries a large bag of papers containing both local and national guidance on the management of common cases/incidents. An electronic on call pack may provide a suitable practical alternative to large paper based systems and help professionals deliver out of hours health protection advice and response to incidents. Methods We developed and piloted an electronic on call pack in Hertfordshire for use at the health protection unit level containing key local and national guidelines, contact information and useful references. The on-call pack was initially piloted using a laptop and more recently using a personal digital assistant (PDA. The use of the on-call pack was evaluated. Results Key advantages of the electronic system include reduced size, faster access to information that is clearly indexed and the relative ease of updating information. As part of the pilot, the electronic on call pack was presented to a local and regional training meeting with good response from participants using qualitative and quantitative methods. Conclusion It is anticipated that with suitable evaluation this system can be adapted and utilised by other health protection practitioners. This system provides a fast, reliable and easily maintained source of information for the public health on-call team.

  11. Why routine intensive care unit admission after elective open infrarenal Abdominal Aortic Aneurysm repair is no longer an evidence based practice.

    LENUS (Irish Health Repository)

    Ryan, David

    2012-01-31

    BACKGROUND: Elective open infrarenal Abdominal Aortic Aneurysm (AAA) repair is major surgery performed on high-risk patients. Routine ICU admission postoperatively is the current accepted standard of care. Few of these patients actually require a level of care that cannot be provided just as effectively in a surgical high dependency unit (HDU). Our aim was to determine, \\'can high risk patients that will require ICU admission postoperatively be reliably identified preoperatively?\\'. METHODS: A retrospective analysis of all elective open infrarenal AAA repairs in our institution over a 3-year period was performed. The Estimation of Physiological Ability and Surgical Stress (E-PASS) model was used as our risk stratification tool for predicting post-operative morbidity. Renal function was also considered as a predictor of outcome, independent of the E-PASS. RESULTS: 80% (n = 16) were admitted to ICU. Only 30% (n = 6) of the total study population necessitated intensive care. There were 9 complications in 7 patients in our study. The E-PASS comprehensive risk score (CRS)\\/Surgical stress score (SSS) were found to be significantly associated with the presence of a complication (p = 0.009)\\/(p = 0.032) respectively. Serum creatinine (p = 0.013) was similarly significantly associated with the presence of a complication. CONCLUSIONS: The E-PASS model possessing increasing external validity is an effective risk stratification tool in safely deciding the appropriate level of post-operative care for elective infrarenal AAA repairs.

For the case that the power supply can not meet the minimum power consumption of the consumers, two admission control algorithms are designed, combining with distributed power consumption scheduling and real-time pricing. Simulation results show that the admission control makes the consumers meet the minimum power consumption, ensure the power quality of the consumers, and balance the supply and the demand in smart grid.

  13. Contingencies of Value: Devices and Conventions at a Design School Admission Test

    Directory of Open Access Journals (Sweden)

    Sara Malou Strandvad

    2014-12-01

    Full Text Available Based on a study of the admission test at a design school, this paper investigates the contingencies of aesthetic values as these become visible in assessment practices. Theoretically, the paper takes its starting point in Herrnstein Smith's notion of 'contingencies of values' and outlines a pragmatist ground where cultural sociology and economic sociology meet. Informed by the literature on cultural intermediaries, the paper discusses the role of evaluators and the devices which accompany them. Whereas studies of cultural intermediaries traditionally apply a Bourdieusian perspective, recent developments within this field of literature draws inspiration from the so-called "new new economic sociology," which this paper adds to. While the admission test is easily described as a matter of overcoming "subjective" aesthetic evaluations by means of "objective" and standardized assessment criteria, the paper does not accept this storyline. As an alternative, the paper outlines the contingencies of values which are at play at the admission test, composed of official assessment criteria and scoring devices together with conventions within the world of design, and set in motion by interactions with the objects that applicants submit.

    Full Text Available In this paper we propose a concurrent admission control scheme for the QoS sensitivity traffic in core-stateless networks. In this scheme, the ingress router of core-stateless network domain is capable of performing admissibility test in concurrent for requests by per-assigning core-link resource to each edge routers. Then, we introduce a novel two phase token passing mechanism to adaptively optimize the proportion of bandwidth dividing among contending edge routers according to the dynamic of their traffic. In addition, we adopt a measurement based admission decisionmaking criterion to gain the benefit of high utilization of statistical multiplexing. Our simulation results are very promising indicating that even under very high request load it is possible to perform admission control and resource allocation in concurrent without suffering in terms of response time, packet loss rate, or utilization.

    The social brain hypothesis predicts that humans have an average of about 150 relationships at any given time. Within this 150, there are layers of friends of an ego, where the number of friends in a layer increases as the emotional closeness decreases. Here we analyse a mobile phone dataset, firstly, to ascertain whether layers of friends can be identified based on call frequency. We then apply different clustering algorithms to break the call frequency of egos into clusters and compare the number of alters in each cluster with the layer size predicted by the social brain hypothesis. In this dataset we find strong evidence for the existence of a layered structure. The clustering yields results that match well with previous studies for the innermost and outermost layers, but for layers in between we observe large variability.

    Wildfires have become a major environmental concern in many Southern European countries over the past few decades. This includes Portugal, where, on average, some 100 000 ha of rural lands are affected by wildfire every year. While policies, laws, plans and public expenditure in Portugal continue to be largely directed towards fire combat and, arguably, to a lesser extent fire prevention, there has only recently been increasing attention for post-fire land management. For example following frequent and several large wildfires during the summer of 2010, so-called emergency stabilization measures were implemented in 16 different burnt areas in northern and central Portugal, using funds of the EU Rural Development Plan in Portugal (PRODER). The measures that were implemented included mulching (i.e. application of a protective layer of organic material), seeding and the construction of log barriers. However, the effectiveness of the implemented measures has not been monitored or otherwise assessed in a systematic manner. In fact, until very recently none of the post-fire emergency stabilization measures contemplated under PRODER seem to have been studied in an exhaustive manner in Portugal, whether under laboratory or field conditions. Prats et al. (2012, 2013, 2014) tested two of these measures by field trials, i.e. hydro-mulching and forest residue mulching. The authors found both measures to be highly effective in terms of reducing overland flow and especially erosion. It remains a challenge, however, to assess the effectiveness of these and other measures in a broader context, not only beyond overland flow and sediment losses but also beyond the spatio-temporal scale that are typical for such field trials (plots and the first two years after fire). This challenge will be addressed in the Portuguese case study of the RECARE project. Nonetheless, the present study wants to be a first attempt at an ecosystem services-based assessment of mulching as a post

    prescriptions were largely responsible for improved guideline adherence with antiplatelets and statins, most of the apparent improvement in ACE inhibitor and ARB use was the result of identifying an acceptable reason for not having them prescribed. Conclusion: This hypothesis generating pilot study supports the findings of others that there is suboptimal prescription of pharmacologic risk reduction therapies in the PAD population. Admission to a vascular service increases these rates. Nevertheless, some patients are still not receiving evidence-based treatment at discharge even after consideration of acceptable reasons. Strategies are needed to improve PAD guideline adherence in both the community at large and the vascular surgery service. Keywords: guideline adherence, vascular protection, risk reduction

    Full Text Available CAC (Call Admission Control plays a significant role in providing QoS (Quality of Service in mobile wireless networks. In addition to much research that focuses on modified Mobile IP to get better efficient handover performance, CAC should be introduced to Mobile IP-based network to guarantee the QoS for users. In this paper, we propose a CAC scheme which incorporates multiple traffic types and adjusts the admission threshold dynamically using fuzzy control logic to achieve better usage of resources. The method can provide QoS in Mobile IPv6 networks with few modifications on MAP (Mobility Anchor Point functionality and slight change in BU (Binding Update message formats. According to the simulation results, the proposed scheme presents good performance of voice and video traffic at the expenses of poor performance on data traffic. It is evident that these CAC schemes can reduce the probability of the handoff dropping and the cell overload and limit the probability of the new call blocking.

    Urinary tract infections (UTIs) caused by uropathogenic Escherichia coli (UPEC) are common infections in humans. Despite the substantial healthcare cost represented by these infections, the human immune response associated with the infection immediately following the onset of symptoms in patients remains largely undefined. We performed a prospective study aimed at defining the milieu of urinary cytokines in adult inpatients in the 24-48 h period immediately following hospital admission for acute cystitis due to UPEC. Urine samples, analyzed using 27-target multiplex protein assays, were used to generate immune profiles for patients and compared to age- and gender-matched healthy controls. The levels of multiple pro-inflammatory cytokines were significantly elevated in urine as a result of infection, an observation consistent with prior findings in murine models and clinical literature. We also identified significant responses for several novel factors not previously associated with the human response to UTI, including Interleukin (IL)-4, IL-7, IL-9, IL-17A, eotaxin, Granulocyte-macrophage colony-stimulating factor (GM-CSF) and several growth factors. These data establish crucial parallels between the human immune response to UPEC and murine model UTI studies, and emphasize the complex but poorly defined nature of the human immune response to UPEC, particularly in the immediate period following the onset of symptoms for acute cystitis.

    Full Text Available Previous researches have shown that project – based learning has contributed positive impact on students’ learning experience. However, there is a lack of in-depth studies to explore on the process of conducting project-based learning in language classroom specifically in Universiti Malaysia Kelantan. This research reports on a case study conducted at an Entrepreneurial University in Kelantan. The research is based on the implementation of drama and entrepreneurial project that was assigned to the students as a part of their assessment for an English course. The study aimed to find out whether the Project – Based Learning could stimulate undergraduates’ language skills and entrepreneurial attributes. It also aimed to investigate on the perceptions of the undergraduates towards the project. This project was carried out in one semester starting from February 2014 until May 2014. A number of 30 participants were selected for this research and they were asked to reflect and write about their experience in preparing for the drama presentation as well as organizing a booth for the project. The data for this research derived from reflective journals and questionnaire (closed and open-ended questions therefore this research is considered as mixed-method research. The findings inferred that the Project-Based Learning receives positive acceptance from the students as majority of the students claimed that the project helped to build up their confidence level when communicating in English during the discussion, presentation and performance as well as improving their teamwork skills. However, when the students were asked about the challenges that they have faced in the process of undertaking the project, they claimed that they had problems to manage the group members and to find suppliers. This research also suggests few recommendations and suggestions for improvement. Based on the findings from this study, it is suggested that Project-Based Learning

    Immunosuppression management in kidney transplantation has evolved to include an increasingly diverse choice of medications. Although informed by patient and donor characteristics, choice of immunosuppression regimen varies widely across transplant programs. Using a novel database integrating national transplant registry and pharmacy fill records, immunosuppression use at 6-12 and 12-24 mo after transplant was evaluated for 22 453 patients transplanted in 249 U.S. programs in 2005-2010. Use of triple immunosuppression comprising tacrolimus, mycophenolic acid or azathioprine, and steroids varied widely (0-100% of patients per program), as did use of steroid-sparing regimens (0-77%), sirolimus-based regimens (0-100%) and cyclosporine-based regimens (0-78%). Use of triple therapy was more common in highly sensitized patients, women and recipients with dialysis duration >5 years. Sirolimus use appeared to diminish over the study period. Patient and donor characteristics explained only a limited amount of the observed variation in regimen use, whereas center choice explained 30-46% of the use of non-triple-therapy immunosuppression. The majority of patients who received triple-therapy (79%), cyclosporine-based (87.6%) and sirolimus-based (84.3%) regimens continued them in the second year after transplant. This population-based study of immunosuppression practice demonstrates substantial variation in center practice beyond that explained by differences in patient and donor characteristics.

    This paper focuses on the admissible consensus problem for heterogeneous descriptor multi-agent systems. Based on algebra, graph and descriptor system theory, the necessary and sufficient conditions are proposed for heterogeneous descriptor multi-agent systems achieving admissible consensus. The provided conditions depend on not only the structure properties of each agent dynamics but also the topologies within the descriptor multi-agent systems. Moreover, an algorithm is given to design the novel consensus protocol. A numerical example demonstrates the effectiveness of the proposed design approach.

    2008-01-01

    This paper describes a two-level cross-talked admission control mechanism that guarantees qual-ity of service (QoS) requirements for multimedia applications over wireless local area networks (WLANs). An enhanced distributed channel access analytical model is used to compute the maximum number of admitted users according to the QoS requirements and the packet arrival characters. Then, some channel resources are reserved for handoff calls based on the maximum number of admitted users and the call-level traffic model. The channel utilization ratio is also measured to reflect the current system traffic load. The maximum number of admitted users and the channel utilization ratio are used for admission control for applications with QoS requirements in the call level and for rate control of best effort applications in the packet level using the p-nonacknowledgement scheme. Thus, the QoS requirements are statistically guaranteed while the system is efficiently utilized. Simulations validate the effectiveness of this mechanism to guarantee the QoS and bandwidth utilization.

    Full Text Available The rapid growth of wireless communication and its persistent use influences all walks of life. Mobile WiMAX IEEE 802.16e standard enabled convergence of mobile and fixed broadband networks through a common wide-area radio-access technology and flexible network architecture. It aims to provide seamless support to its users but an inevitable is that the long delay which occurs during the handoff management in every network process. This paper proposes a Dynamic Interval based Processing Algorithm to separate ping-pong users from the pool of users and to process them separately thus reducing the overhead of network re-entry process. Incoming users are divided into three categories like new user, old user and ping pong user. New user should undergo all the phases of network entry process, old user is provided with authentication key which leads to skipping of steps in generation of keys. Proposed algorithm deals with identifying the ping pong users by calculating the inter arrival duration and rate with same base station. When assured authenticated ping-pong users enter the network next time within the allotted time they will be provided with last used Traffic Encryption Key (TEK thus bypassing key generation phase . It is observed that the proposed work performs the authentication phase and cancels the key generation phase which leads to minimum network entry delay and it saves to the maximum of 80% processing time. The network model was developed using Network Simulator and the algorithm was implemented in MATLAB GUIDE which gets connected to the database developed in MYSQL.This approach is justified through its timing analysis result which proves the efficient swift in the handoff processes.

    The study of acoustic communication in animals often requires not only the recognition of species specific acoustic signals but also the identification of individual subjects, all in a complex acoustic background. Moreover, when very long recordings are to be analyzed, automatic recognition and identification processes are invaluable tools to extract the relevant biological information. A pattern recognition methodology based on hidden Markov models is presented inspired by successful results obtained in the most widely known and complex acoustical communication signal: human speech. This methodology was applied here for the first time to the detection and recognition of fish acoustic signals, specifically in a stream of round-the-clock recordings of Lusitanian toadfish (Halobatrachus didactylus) in their natural estuarine habitat. The results show that this methodology is able not only to detect the mating sounds (boatwhistles) but also to identify individual male toadfish, reaching an identification rate of ca. 95%. Moreover this method also proved to be a powerful tool to assess signal durations in large data sets. However, the system failed in recognizing other sound types. PMID:26723348

    1. Generically based pharmaceutical systems exist in a few countries of the world, such as Iran. Most developed countries have free market pharmaceutical systems. Drug-related problems (DRP) have been reported mostly in the Western world but few data are available for generic systems. In this study, we tried to measure the prevalence of drug-related problems leading to hospital admissions in Isfahan, Iran. 2. One thousand consecutive hospital admissions in three major teaching hospitals were studied for a period of 6 months for the presence of DRP as a cause of hospital admissions. Two subcategories of DRP were considered: (i) drug therapy failure; and (ii) adverse drug reactions. Preventability and outcome measures were also assessed. Medications responsible for DRP were classified according to the Anatomic Therapeutic Chemical (ATC) classification of the World Health Organization. 3. Of the 1000 admissions studied, 115 (11.5%) were owing to DRP, 81% as a result of drug therapy failure and 19% as adverse drug reactions. A total of 106 out of the 115 DRP cases (92%) were either preventable or probably preventable, most of which had to do with either prescriber or patient error. An overview of DRP showed that 58.3% resulted in complete recovery, 33.9% in relative recovery and 7.8% in death. Close to 1% of hospital admissions resulted in DRP-related deaths. 4. The overall prevalence of hospital admissions caused by DRP is similar to that in free market pharmaceutical systems. The high preventability rate of these problems should alert clinicians and policy makers to design strategies to curtail this. Also, reasons for differences in subtypes of DRP between the results of this study and those of the literature from free market systems needs to be investigated further.

    This paper discusses admissibilities of estimators in a class of linear models,which include the following common models:the univariate and multivariate linear models,the growth curve model,the extended growth curve model,the seemingly unrelated regression equations,the variance components model,and so on.It is proved that admissible estimators of functions of the regression coefficient β in the class of linear models with multivariate t error terms,called as Model II,are also ones in the case that error terms have multivariate normal distribution under a strictly convex loss function or a matrix loss function.It is also proved under Model II that the usual estimators of β are admissible for p 2 with a quadratic loss function,and are admissible for any p with a matrix loss function,where p is the dimension of β.

  11. Admissibility under extension of number fields

    CERN Document Server

    Danny, Neftin

    2009-01-01

    A finite group G is K-admissible if there is a G-crossed product K-division algebra. In this manuscript we study the behavior of admissibility under extension of number fields M/K. While tame admissibility goes down, wild admissibility goes up: if G is a wildly K-admissible p-group, for an odd prime p, having the Grunwald-Neukirch (GN) property over M, then G is also wildly M-admissible. We generalize this statement to odd order groups $G$ with the GN-property over M, provided that the extension locally avoids a certain list of 29 sensitive extensions. On the other hand, we give an example of a quadratic extension M/K with a 2-group which is wildly K-admissible, and not even M-preadmissible. We also consider eight possible notions of being M-admissible with respect to a subfield K, where the field of definition of the division algebra, the maximal subfield or the Galois group is asserted to be $K$. We provide counterexamples for each implication between these notions which is not proved in the text.

  14. Can advanced paramedics in the field diagnose patients and predict hospital admission?

    LENUS (Irish Health Repository)

    Cummins, Niamh Maria

    2013-02-13

    BACKGROUND: Accurate patient diagnosis in the prehospital environment is essential to initiate suitable care pathways. The advanced paramedic (AP) is a relatively recent role in Ireland, and refers to a prehospital practitioner with advanced life-support skills and training. OBJECTIVES: The objectives of this study were to compare the diagnostic decisions of APs with emergency medicine (EM) physicians, and to investigate if APs, as currently trained, can predict the requirement for hospital admission. METHODS: A prospective study was initiated, whereby each emergency ambulance call received via the statutory 999 system was recorded by the attending AP. The AP was asked to provide a clinical diagnosis for each patient, and to predict if hospital admission was required. The data was then cross-referenced with the working diagnosis of the receiving emergency physician and the hospital admission records. RESULTS: A total of 17 APs participated in the study, and 1369 emergency calls were recorded over a 6-month period. Cases where a general practitioner attended the scene were excluded from the concordance analysis. Concordance with the receiving emergency physician represents 70% (525\\/748) for all cases of AP diagnosis, and is mirrored with 70% (604\\/859) correct hospital admission predictions. CONCLUSIONS: AP diagnosis and admission prediction for emergency calls is similar to other emergency medical services systems despite the relative recency of the AP programme in Ireland. Recognition of non-concordance case types may identify priorities for AP education, and drive future AP practice in areas such as \\'treat and refer\\'.

    1996-01-01

    A fixture process and method is provided for developing a complete set of all admissible fixture designs for a workpiece which prevents the workpiece from translating or rotating. The fixture processor generates the set of all admissible designs based on geometric access constraints and expected applied forces on the workpiece. For instance, the fixture processor may generate a set of admissible fixture designs for first, second and third locators placed in an array of holes on a fixture plate and a translating clamp attached to the fixture plate for contacting the workpiece. In another instance, a fixture vice is used in which first, second, third and fourth locators are used and first and second fixture jaws are tightened to secure the workpiece. The fixture process also ranks the set of admissible fixture designs according to a predetermined quality metric so that the optimal fixture design for the desired purpose may be identified from the set of all admissible fixture designs.

    Full Text Available Indian University Admission is a complex phenomenon encompassing various factors both tangible and intangible. Apart from Merit - Caste, Community and Religion play a crucial role in getting admission to various courses offered by Universities. The Single Window Admission System followed by almost all Government Universities (for example: Anna University, Chennai is, so far, the best practice to offer Admission sought by student community. But, still, in Private Universities, the Admission process is done manually since number of students seeking a course is smaller in size. This manual process is fraught with some drawbacks: such as slower in time, cumbersome and costlier, bias by the Admission Officer, manual errors while processing, due to influence exercised by powerful people qualified students not getting their course of choice and unqualified students getting into their course of willingness and etc. This paper addresses these problems via neural network architecture based Admission system which will eliminate all the pitfalls and drawbacks inherent in the current system and offers a smooth, clearer, easier and cost effective way of student admission system implementation in Indian Universities.

  9. Examining the effectiveness of discriminant function analysis and cluster analysis in species identification of male field crickets based on their calling songs.

    Directory of Open Access Journals (Sweden)

    Ranjana Jaiswara

    Full Text Available Traditional taxonomy based on morphology has often failed in accurate species identification owing to the occurrence of cryptic species, which are reproductively isolated but morphologically identical. Molecular data have thus been used to complement morphology in species identification. The sexual advertisement calls in several groups of acoustically communicating animals are species-specific and can thus complement molecular data as non-invasive tools for identification. Several statistical tools and automated identifier algorithms have been used to investigate the efficiency of acoustic signals in species identification. Despite a plethora of such methods, there is a general lack of knowledge regarding the appropriate usage of these methods in specific taxa. In this study, we investigated the performance of two commonly used statistical methods, discriminant function analysis (DFA and cluster analysis, in identification and classification based on acoustic signals of field cricket species belonging to the subfamily Gryllinae. Using a comparative approach we evaluated the optimal number of species and calling song characteristics for both the methods that lead to most accurate classification and identification. The accuracy of classification using DFA was high and was not affected by the number of taxa used. However, a constraint in using discriminant function analysis is the need for a priori classification of songs. Accuracy of classification using cluster analysis, which does not require a priori knowledge, was maximum for 6-7 taxa and decreased significantly when more than ten taxa were analysed together. We also investigated the efficacy of two novel derived acoustic features in improving the accuracy of identification. Our results show that DFA is a reliable statistical tool for species identification using acoustic signals. Our results also show that cluster analysis of acoustic signals in crickets works effectively for species

    Biagini, Sara

    2009-01-01

    The choice of admissible trading strategies in mathematical modelling of financial markets is a delicate issue, going back to Harrison and Kreps (1979). In the context of optimal portfolio selection with expected utility preferences this question has been a focus of considerable attention over the last twenty years. We propose a novel notion of admissibility that has many pleasant features -- admissibility is characterized purely under the objective measure $P$; the wealth of any admissible strategy is a supermartingale under all pricing measures; local boundedness of the price process is not required; neither strict monotonicity, strict concavity nor differentiability of the utility function are necessary; the definition encompasses both the classical mean-variance preferences and the monotone expected utility. For utility functions finite on the real line, our class represents a minimal set containing simple strategies which also contains the optimizer, under conditions that are substantially milder than th...

We completely determine the logical implications between all variants.

    This study was designed to elucidate psychiatric admission rates for native Swedes and foreign-born individuals during the period 1991-1994, when Sweden had a great influx of refugees. During the same period, and even earlier, psychiatric in-patient care had been reduced. Tests of differences between Swedes and foreign-born individuals in first psychiatric admission rates were performed using Poisson regressions, and the risk of a readmission was assessed using a proportional hazard model. Foreign-born individuals and native Swedes, both males and females, showed a similar admission pattern with regard to the number of admissions. Foreign-born males under 55 years of age and foreign-born females under 35 years of age had significantly higher admission rates than native Swedes. In total, native Swedes, both males and females, were hospitalized for a significantly longer period than the foreign-born subjects. About 43% of the patients were readmitted. The risk of a readmission was significantly increased among those with a high rate of internal migration. The high admission rates for young foreign-born individuals might be explained by a high incidence of mental illness owing to the trauma of being violently forced to migrate, acculturation difficulties, or unsatisfactory social circumstances such as high unemployment. The shorter hospitalization time could be due to undertreatment or less serious mental illness. PMID:9718235

This measurement-based AC scheme acceptsflows by default, but based on the changes in thenetwork QoS, it makes regressive decisions on the possible flow rejection, thus bringing cognition tothenetwork path. TheREgressive Admission Control (REAC system consists of three modules performing thenecessary tasks:QoS measurements, traffic identification, and the actual AC decision making and flowcontrol. There are two major advantages with this new scheme; (i significant optimization of theconnection start-up phase, and (ii continuous QoSknowledge of the accepted streams. In fact, the lattercombined with the REAC decisions can enable guaranteed QoS without requiring any QoS support fromthe network. REAC was tested on a video streaming test bed and proved to have a timely and realisticmatch between the network's QoS and the video quality.

    2015-12-01

    Full Text Available Hospitalisation for adversity-related injury (violent, drug/alcohol-related, or self-inflicted injury has been described as a "teachable moment", when intervention may reduce risks of further harm. Which adolescents are likely to benefit most from intervention strongly depends on their long-term risks of harm. We compared 10-y risks of mortality and re-admission after adversity-related injury with risks after accident-related injury.We analysed National Health Service admissions data for England (1 April 1997-31 March 2012 for 10-19 y olds with emergency admissions for adversity-related injury (violent, drug/alcohol-related, or self-inflicted injury; n = 333,009 or for accident-related injury (n = 649,818. We used Kaplan-Meier estimates and Cox regression to estimate and compare 10-y post-discharge risks of death and emergency re-admission. Among adolescents discharged after adversity-related injury, one in 137 girls and one in 64 boys died within 10 y, and 54.2% of girls and 40.5% of boys had an emergency re-admission, with rates being highest for 18-19 y olds. Risks of death were higher than in adolescents discharged after accident-related injury (girls: age-adjusted hazard ratio 1.61, 95% CI 1.43-1.82; boys: 2.13, 95% CI 1.98-2.29, as were risks of re-admission (girls: 1.76, 95% CI 1.74-1.79; boys: 1.41, 95% CI 1.39-1.43. Risks of death and re-admission were increased after all combinations of violent, drug/alcohol-related, and self-inflicted injury, but particularly after any drug/alcohol-related or self-inflicted injury (i.e., with/without violent injury, for which age-adjusted hazard ratios for death in boys ranged from 1.67 to 5.35, compared with 1.25 following violent injury alone (girls: 1.09 to 3.25, compared with 1.27. The main limitation of the study was under-recording of adversity-related injuries and misclassification of these cases as accident-related injuries. This misclassification would attenuate the relative risks of death

    Avionics full duplex switched ethernet (AFDX) is a switched interconnection technology developed to provide reliable data exchange with strong data transmission time guarantees in internal communication of the spacecraft or aircraft. Virtual link (VL) is an important concept of AFDX to meet quality of service (QoS) requirements in terms of end-to-end message deadlines. A VL admission control algorithm in AFDX network under hard real-time (HRT) constraints is studied. Based on the scheduling principle of AFDX protocol, a packet scheduling scheme under HRT constraints is proposed, and after that an efficient VL admission control algorithm is presented. Analytical proof that the algorithm can effectively determine whether VL should be admitted is given. Finally simulative examples are presented to promote the conclusion.

    1996-10-01

    This study aimed to explore the relationship between hospital admissions for asthma and socioeconomic deprivation. A retrospective study examined one year of hospital admissions for asthma in the West Midlands region of England (n = 10,044), and in one of the region's wealthier districts, Worcester (n = 251). Age standardized admission ratios (SARs) for asthma, and the routes of hospital admission, were compared with the Towns- end Deprivation Index for the place of residence. Asthma SAR was strongly associated with deprivation as measured by the Towns end Index for the district of residence (Spearman rank correlation coefficient rho = 0.65; p = 0.004). Asthma admission rates for all age groups, except those aged over 65 yrs, were higher in poorer districts. A significantly greater proportion of emergency admissions in poorer districts came via Accident and Emergency departments, rather than general practitioner referrals (rho = 0.76; p Townsend Index for the ward of residence (rho = 0.39; p < 0.001). This remained significant after excluding repeat admissions (rho = 0.45; p < 0.001). We conclude that asthma admissions are strongly associated with deprivation in the community. Differences in the health care received during acute exacerbations by asthma patients from different economic backgrounds is likely to be an important factor in this relationship. PMID:8902471

    The time of admission to a hospital, especially when unplanned, has been reported as the most stressful moment of hospitalization for both parents and children (Odievre, 2001). This qualitative study explored parents and hospital staff's perceptions and experiences related to the process of admission to a pediatric unit. Focus groups, two with parents (total n = 12) and one with health care professionals (n = 6), were conducted, and content analysis inspired by Graneheim and Lundman (2004) was performed. Parents identified four categories of perceptions: 1) management of an uncertain situation at the time of admission, 2) feelings related to the child's illness, 3) parent perception of professional's performance, and 4) parent experience of their role. Health care professionals identified two categories: 1) hospital admission as a continuous care process, and 2) undertaking improvements in the admission process. A common theme emerged about the importance of parents' trust in professionals in order to build a therapeutic relationship. Findings underscore the need for strategies to improve the hospital pediatric admission process based on a parent-professional relationship of trust and confidence through continuous quality communication and support. These strategies would include providing a nurse in charge of the admission process to assure continuity of care throughout the child's hospitalization.

    This paper describes a load-dependent multi-stage admission control suitable for next generation systems. The concept uses decision polling in entities located at different levels of the architecture hierarchy and based on the load to activate a sequence of actions related to the admission...... of a user to the network, i.e., the ranking of the intermediate decisions is dynamic. The decision is controlled by passing a token between the base station (BS) and the gateway (GW), thereby considering the load status of the BS and the backhaul network. A token is assigned to the entity with the highest...... load. Each admission request will issue a flag whose colour will reflect the load level in this entity and will determine the correct sequence of the required admission control actions....

    2006-01-01

    Admission control is an important strategy for Quality of Service (QoS) provisioning in Asynchronous Transfer Mode (ATM) networks. Based on a control-theory model of resources on-Demand Allocation (DA) protocol, the paper studies the effect of the protocol on the statistical characteristics of network traffic,and proposes a combined connection admission control algorithm with the DA protocol to achieve full utilization of link resources in satellite communication systems. The proposed algorithm is based on the cross-layer-design approach. Theoretical analysis and system simulation results show that the proposed algorithm can admit more connections within certain admission thresholds than one that does not take into account the DA protocol. Thus, the proposed algorithm can increase admission ratio of traffic sources for satellite ATM networks and improve satellite link utilization.

  15. An Autonomous Distributed Admission Control Scheme for IEEE 802.11 DCF

    CERN Document Server

    Patil, Preetam

    2007-01-01

    Admission control as a mechanism for providing QoS requires an accurate description of the requested flow as well as already admitted flows. Since 802.11 WLAN capacity is shared between flows belonging to all stations, admission control requires knowledge of all flows in the WLAN. Further, estimation of the load-dependent WLAN capacity through analytical model requires inputs about channel data rate, payload size and the number of stations. These factors combined point to a centralized admission control whereas for 802.11 DCF it is ideally performed in a distributed manner. The use of measurements from the channel avoids explicit inputs about the state of the channel described above. BUFFET, a model based measurement-assisted distributed admission control scheme for DCF proposed in this paper relies on measurements to derive model inputs and predict WLAN saturation, thereby maintaining average delay within acceptable limits. Being measurement based, it adapts to a combination of data rates and payload sizes, ...

  1. The therapeutic relationship after psychiatric admission.

    LENUS (Irish Health Repository)

    Roche, Eric

    2014-03-01

    The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

  7. Bernoulli measure of complex admissible kneading sequences

    CERN Document Server

    Bruin, Henk

    2012-01-01

    Iterated quadratic polynomials give rise to a rich collection of different dynamical systems that are parametrized by a simple complex parameter $c$. The different dynamical features are encoded by the \\emph{kneading sequence} which is an infinite sequence over $\\{0,\\1\\}$. Not every such sequence actually occurs in complex dynamics. The set of admissible kneading sequences was described by Milnor and Thurston for real quadratic polynomials, and by the authors in the complex case. We prove that the set of admissible kneading sequences has positive Bernoulli measure within the set of sequences over $\\{0,\\1\\}$.

  8. Entropy Production and Admissibility of Shocks

    Institute of Scientific and Technical Information of China (English)

    Tai-Ping Liu; Tommaso Ruggeri

    2003-01-01

    In shock wave theory there are two considerations in selecting the physically relevant shock waves.There is the admissibility criterion for the well-posedness of hyperbolic conservation laws. Another consideration concerns the entropy production across the shocks. The latter is natural from the physical point of view, but is not sufficient in its straightforward formulation, if the system is not genuinely nonlinear. In this paper we propose the principles of increasing entropy production and that of the superposition of shocks. These principles are shown to be equivalent to the admissibility criterion.

  9. Admission control with long-range dependence traffic input

    RAO Yun-hua; ZOU Xue-cheng

    2005-01-01

    The admission control scheme is investigated for a FIFO self-similar queuing system with Quality of Service (QoS) performance guarantees. Since the self-similar queuing system performance analysis is often carried out under the condition of infinite buffer, it is difficult to deduce the upper boundary of buffer overflow probability. To overcome this shortcoming, a simple overflow condition is proposed, which defines a buffer overflow occurrence whenever the arrival rate exceeds the service rate. The analytic formula for the buffer overflow probability upper boundary is easily obtained under this condition. The required bandwidth upper boundary with long-range dependence input and determined overflow probability is then derived from this formula. Based on the above analytic formulas, the upper boundaries of the admission control regions for homogeneous and heterogeneous long-range dependence traffic sources are separately obtained. Finally, an effective admission control scheme for long-range dependence input is proposed. Simulation studies with real traffic have confirmed the validity of these results.

    Full Text Available To test the impact of a UK pay-for-performance indicator, the Quality and Outcomes Framework (QOF dementia review, on three types of hospital admission for people with dementia: emergency admissions where dementia was the primary diagnosis; emergency admissions for ambulatory care sensitive conditions (ACSCs; and elective admissions for cataract, hip replacement, hernia, prostate disease, or hearing loss.Count data regression analyses of hospital admissions from 8,304 English general practices from 2006/7 to 2010/11. We identified relevant admissions from national Hospital Episode Statistics and aggregated them to practice level. We merged these with practice-level data on the QOF dementia review. In the base case, the exposure measure was the reported QOF register. As dementia is commonly under-diagnosed, we tested a predicted practice register based on consensus estimates. We adjusted for practice characteristics including measures of deprivation and uptake of a social benefit to purchase care services (Attendance Allowance.In the base case analysis, higher QOF achievement had no significant effect on any type of hospital admission. However, when the predicted register was used to account for under-diagnosis, a one-percentage point improvement in QOF achievement was associated with a small reduction in emergency admissions for both dementia (-0.1%; P=0.011 and ACSCs (-0.1%; P=0.001. In areas of greater deprivation, uptake of Attendance Allowance was consistently associated with significantly lower emergency admissions. In all analyses, practices with a higher proportion of nursing home patients had significantly lower admission rates for elective and emergency care.In one of three analyses at practice level, the QOF review for dementia was associated with a small but significant reduction in unplanned hospital admissions. Given the rising prevalence of dementia, increasing pressures on acute hospital beds and poor outcomes associated with

    Lakshmanan Senthilkumar

    2007-02-01

    Full Text Available Real time traffic adopting UDP at the transport layer needs some quality of service. It is offered through an admission control scheme. This paper adopts one such scheme which is extended for elastic traffics adopting TCP at the transport layer. The proposed scheme operates on reserving network resources on a proactive manner. It is based on the principle of telephone networks Erlang-B model. The blocking probability measured is used as a flow admission decision parameter. The effectiveness of the proposed admission control algorithm is determined here through simulation. It offers a fair admission rate to both UDP and TCP traffic flows. It also results in a better bottleneck link utilization at a comparatively lower overhead traffic.

    2004-01-01

    A new admission control algorithm considering the network self-similar access characteristics is proposed.Taking advantage of the mathematical model of the network traffic admission control which can effectively overcome the self-similar characteristics of the network requests, through the scheduling of the differential service queue based on priority while at the same time taking into account various factors including access characteristics of requests, load information, etc, smoothness of the admission control is ensured by the algorithm proposed in this paper.We design a non-linear self-adapting control algorithm by introducing an exponential admission function, thus overcomes the negative aspects introduced by static threshold parameters.Simulation results show that the scheme proposed in this paper can effectively improve the resource utilization of the clusters, while at the same time protecting the service with high priority.Our simulation results also show that this algorithm can improve system stability and reliability too.

    2013-05-01

    In light of the structural and content changes to the Medical College Admission Test (MCAT) to be implemented in 2015 and the recent diversity- and social-accountability-based recommendations of the Future of Medical Education in Canada (FMEC) project, the authors review and reexamine the use of the MCAT exam in Canadian medical school admissions decisions.This Perspective article uses a point-counterpoint format to discuss three main advantages and disadvantages of using the MCAT exam in the medical school admissions process, from a Canadian perspective. The authors examine three questions regarding the FMEC recommendations and the revised MCAT exam: (1) Is the MCAT exam equal and useful in Canadian admissions? (2) Does the MCAT exam affect matriculant diversity? and (3) Is the MCAT exam a strong predictor of future performance? They present the most recent arguments and evidence for and against use of the MCAT exam, with the purpose of summarizing these different perspectives for readers.

    "To determine the effect of job loss on health an investigation was made of admissions to hospitals in 887 men five years before and three years after the closure of a Danish shipyard. The control group comprised 441 men from another shipyard. The information on hospital admissions was obtained from the Danish national register of patients. The relative risk of admission in the control group dropped significantly in terms of the number of men admitted from the study group from 1.29 four to five years before closure to 0.74 in the three years after closure. This was especially true of admissions due to accidents (1.33 to 0.46) and diseases of the digestive system (4.53 to 1.03). For diseases of the circulatory system, particularly cardiovascular diseases, the relative risk increased from 0.8 to 1.60, and from 1.0 to 2.6 respectively. These changes in risk of illness after redundancy are probably a consequence of a change from the effects of a high risk work environment to the effects of psychosocial stresses such as job insecurity and unemployment."

  18. Preoperative predictive factors for intensive care unit admission after pulmonary resection

    Directory of Open Access Journals (Sweden)

    Liana Pinheiro

    2015-02-01

    Full Text Available Objective: To determine whether the use of a set of preoperative variables can predict the need for postoperative ICU admission. Methods: This was a prospective observational cohort study of 120 patients undergoing elective pulmonary resection between July of 2009 and April of 2012. Prediction of ICU admission was based on the presence of one or more of the following preoperative characteristics: predicted pneumonectomy; severe/very severe COPD; severe restrictive lung disease; FEV1 or DLCO predicted to be < 40% postoperatively; SpO2 on room air at rest < 90%; need for cardiac monitoring as a precautionary measure; or American Society of Anesthesiologists physical status ≥ 3. The gold standard for mandatory admission to the ICU was based on the presence of one or more of the following postoperative characteristics: maintenance of mechanical ventilation or reintubation; acute respiratory failure or need for noninvasive ventilation; hemodynamic instability or shock; intraoperative or immediate postoperative complications (clinical or surgical; or a recommendation by the anesthesiologist or surgeon to continue treatment in the ICU. Results: Among the 120 patients evaluated, 24 (20.0% were predicted to require ICU admission, and ICU admission was considered mandatory in 16 (66.6% of those 24. In contrast, among the 96 patients for whom ICU admission was not predicted, it was required in 14 (14.5%. The use of the criteria for predicting ICU admission showed good accuracy (81.6%, sensitivity of 53.3%, specificity of 91%, positive predictive value of 66.6%, and negative predictive value of 85.4%. Conclusions: The use of preoperative criteria for predicting the need for ICU admission after elective pulmonary resection is feasible and can reduce the number of patients staying in the ICU only for monitoring.

  19. On the freeness of the cyclotomic BMW algebras: admissibility and an isomorphism with the cyclotomic Kauffman tangle algebras

    CERN Document Server

    Wilcox, Stewart

    2009-01-01

    The cyclotomic Birman-Murakami-Wenzl (BMW) algebras B_n^k, introduced by R. H\\"aring-Oldenburg, are a generalisation of the BMW algebras associated with the cyclotomic Hecke algebras of type G(k,1,n) (aka Ariki-Koike algebras) and type B knot theory. In this paper, we prove the algebra is free and of rank k^n (2n-1)!! over ground rings with parameters satisfying so-called "admissibility conditions". These conditions are necessary in order for these results to hold and originally arise from the representation theory of B_2^k, which is analysed by the authors in a previous paper. Furthermore, we obtain a geometric realisation of B_n^k as a cyclotomic version of the Kauffman tangle algebra, in terms of affine n-tangles in the solid torus, and produce explicit bases that may be described both algebraically and diagrammatically. The admissibility conditions are the most general offered in the literature for which these results hold; they are necessary and sufficient for all results for general n.

    2016-01-01

    Background The ICH score is a validated tool for predicting 30-day morbidity and mortality in patients with intracerebral hemorrhage. Aims and/or Hypothesis The aim of this study is to determine if the ICH score calculated 24 hours after admission is a better predictor of mortality than the ICH score calculated on admission. Methods Patients presenting to our center with ICH from 7/08-12/10 were retrospectively identified from our prospective stroke registry. ICH scores were calculated based on initial Glasgow coma scale (GCS) and emergent head computed tomography (CT) on initial presentation and were recalculated after 24 hours. Results A total of 91 patients out of 121 had complete data for admission and 24-hour ICH score. The ICH score changed in 38% from baseline to 24 hours. After adjusting for age, NIHSS on admission, and glucose, ICH score at 24 hours was a significant, independent predictor of mortality (OR = 2.71, 95% CI 1–19–6.20, and P = 0.018), but ICH score on admission was not (OR = 2.14, 95% CI 0.88-5.24, and P = 0.095). Conclusion Early determination of the ICH score may incorrectly estimate the severity and expected outcome after ICH. Calculations of the ICH score 24 hours after admission will better predict early outcomes.

  6. Maternal mortality and morbidity: epidemiology of intensive care admissions in pregnancy.

    Science.gov (United States)

    Senanayake, H; Dias, T; Jayawardena, A

    2013-12-01

    Maternal mortality reviews are used globally to assess the quality of health-care services. With the decline in the number of maternal deaths, it has become difficult to derive meaningful conclusions that could have an impact on quality of care using maternal mortality data. The emphasis has recently shifted to severe acute maternal morbidity (SAMM), as an adjunct to maternal mortality reviews. Due to its heterogeneity, there are difficulties in recognising SAMM. The problem of identifying SAMM accurately is the main issue in investigating them. However, admission to an intensive care unit (ICU) provides an unambiguous, management-based inclusion criterion for a SAMM. ICU data are available across health-care settings prospectively and retrospectively, making them a tool that could be studied readily. However, admission to the ICU depends on many factors, such as accessibility and the availability of high-dependency units, which will reduce the need for ICU admission. Thresholds for admission vary widely and are generally higher in facilities that handle a heavier workload. In addition, not all women with SAMM receive intensive care. However, women at the severe end of the spectrum of severe morbidity will almost invariably receive intensive care. Notwithstanding these limitations, the epidemiology of intensive care admissions in pregnancy will provide valuable data about women with severe morbidity. The overall rate of obstetric ICU admission varies from 0.04% to 4.54%.

    2014-01-30

    The legal status of service users admitted to psychiatric wards is not synonymous with the level of coercion that they can perceive during the admission. This study aimed to identify and describe the proportion of individuals who were admitted voluntarily but experienced levels of perceived coercion comparable to those admitted involuntarily. Individuals admitted voluntarily and involuntarily to three psychiatric hospitals were interviewed using the MacArthur Admission Experience Interview and the Structured Clinical Interview for DSM-IV diagnoses. One hundered sixty-one individuals were interviewed and 22% of the voluntarily admitted service users had levels of perceived coercion similar to that of the majority of involuntarily admitted service users. Voluntarily admitted service users who experienced high levels of perceived coercion were more likely to have more severe psychotic symptoms, have experienced more negative pressures and less procedural justices on admission. Individuals brought to hospital under mental health legislation but who subsequently agreed to be admitted voluntarily and those treated on a secure ward also reported higher levels of perceived coercion. It needs to be ensured that if any service user, whether voluntary or involuntary, experiences treatment pressures or coercion that there is sufficient oversight of the practice, to ensure that individual\\'s rights are respected.

    People in modern societies form different social networks through numerous means of communication. These communication networks reflect different aspects of human's societal structure. The billing records of calls among mobile phone users enable us to construct a directed calling network (DCN) and its Bonferroni network (SVDCN) in which the preferential communications are statistically validated. Here we perform a comparative investigation of the cliques of the original DCN and its SVDCN constructed from the calling records of more than nine million individuals in Shanghai over a period of 110 days. We find that the statistical properties of the cliques of the two calling networks are qualitatively similar and the clique members in the DCN and the SVDCN exhibit idiosyncratic behaviors quantitatively. Members in large cliques are found to be spatially close to each other. Based on the clique degree profile of each mobile phone user, the most active users in the two calling networks can be classified in to seve...

    @@ Conference Theme and Scope The last decade has seen rapid growth of service-based economic activities in many advanced developed economies such as the USA, European and developed Asian countries as well as emerging economies such as China and India. The rapid growth of service activities poses many challenging issues in the design and operation requirements of service systems in order to compete for finite resources in the global marketplace. Research studies have to date revealed incompleteness and loosely coupled findings to answer 1) "what are the driving dynamics for enterprise's service systems?" and 2) "how should services be managed to optimally create timeliness value for its stakeholders?" These are multi- and inter-disciplinary unresolved issues confronting the academia and service practitioners.

    2010-01-01

    We present a study of the reciprocity of human behaviour based on mobile phone usage records. The underlying question is whether human relationships are mutual, in the sense that both are equally active in keeping up the relationship, or is it on the contrary typical that relationships are lopsided, with one party being significantly more active than the other. We study this question with the help of a mobile phone data set consisting of all mobile phone calls between 5.3 million customers of a single mobile phone operator. It turns out that lopsided relations are indeed quite common, to the extent that the variation cannot be explained by simple random deviations or by variations in personal activity. We also show that there is no non-trivial correlation between reciprocity and local network density.

A-chieving a calling allows an individual to experience the meaning of one’s work,mission and a true self. However,not all callings can be achieved,and what is the impact of the calling which you could have chosen but had to give up on your self-concept,career and life? Based on the counterfactual thinking,self-concept and calling-related researches,this paper argues that: ( a) counterfactual self based on calling( CSC) is a new construct paralleling actual self; ( b) CSC has contributed much to theoretical research of calling and counter-factual thinking; ( c) CSC can have direct impact on individual’emotion,cognition,motivation and behav-ior.

  2. Primary Path Reservation Using Enhanced Slot Assignment in TDMA for Session Admission

    Directory of Open Access Journals (Sweden)

    Suresh Koneri Chandrasekaran

    2015-01-01

    Full Text Available Mobile ad hoc networks (MANET is a self-organized collection of nodes that communicates without any infrastructure. Providing quality of service (QoS in such networks is a competitive task due to unreliable wireless link, mobility, lack of centralized coordination, and channel contention. The success of many real time applications is purely based on the QoS, which can be achieved by quality aware routing (QAR and admission control (AC. Recently proposed QoS mechanisms do focus completely on either reservation or admission control but are not better enough. In MANET, high mobility causes frequent path break due to the fact that every time the source node must find the route. In such cases the QoS session is affected. To admit a QoS session, admission control protocols must ensure the bandwidth of the relaying path before transmission starts; reservation of such bandwidth noticeably improves the admission control performance. Many TDMA based reservation mechanisms are proposed but need some improvement over slot reservation procedures. In order to overcome this specific issue, we propose a framework—PRAC (primary path reservation admission control protocol, which achieves improved QoS by making use of backup route combined with resource reservation. A network topology has been simulated and our approach proves to be a mechanism that admits the session effectively.

A review of adaptive control methods of accepting a call in WCDMA networks is discussed, based on the overview of the algorithms used for this purpose, and their comparison. Appropriate comments and conculsions in comparison with the basic characteristics of these algorithms are given. The OVSF codes are explained as well as how the allocation method influences the capacity and probability of blocking.. Introduction We are witnessing a steady increase in the number of demands placed upon modern wireless networks. New applications and an increasing number of users as well as user activities growth in recent years reinforce the need for an efficient use of the spectrum and its proper distribution among different applications and classes of services. Besides humans, the last few years saw different computers, machines, applications, and, in the future, many other devices, RFID applications, and finally networked objects, as a new kind of wireless networks "users". Because of the exceptional rise in the number of users, the demands placed upon modern wireless networks are becoming larger, and spectrum management plays an important role. For these reasons, choosing an appropriate call admission control algorithm is of great importance. Multiple access and resource management in wireless networks Radio resource management of mobile networks is a set of algorithms to manage the use of radio resources with the aim is to maximize the total capacity of wireless systems with equal distribution of resources to users. Management of radio resources in cellular networks is usually located in the base station controller, the base station and the mobile terminal, and is based on decisions made on appropriate measurement and feedback. It is often defined as the maximum volume of traffic load that the system can provide for some of the requirements for the

  4. Of special humanitarian concern: U.S. refugee admissions since passage of the Refugee Act.

    Science.gov (United States)

    Gallagher, D; Forbes, S; Fagan, P W

    1986-01-01

    The Refugee Act of 1980 is the 1st comprehensive legislation on the admission of refugees to the US; in the 5+ years since its enactment, over 500,000 refugees from more than 25 countries have been admitted to the US. This report assesses the effectiveness of the law in achieving its objectives in making and implementing decisions about the admission of refugees. The objectives of the Act include 1) a desire for a humanitarian response to refugee emergencies and a desire for control over that response, 2) a concern that ideological and geographic restrictions on refugee admissions be removed, and 3) a desire to balance international concerns and domestic impacts in making decisions on refugee admissions. The authors conclude that the refugee program does not serve the broad humanitarian purposes of previous parole programs, due to its stringent review requirements. The formal Congressional Consultations on refugee numbers should be rescheduled to allow regular Congressional input. The program needs a contingency budget for changing situations. The program needs more input from nongovernmental agencies and information sources. Recommendations on refugee admission numbers and allocations have not been well substantiated. Determinations as to which refugees are of "special humanitarian concern" are made solely on the basis of nationality; these decisions should also incorporate other factors. Admissions priorities are generally based on ties to this country, but this makes the refugee program a surrogate immigration program. Although the application of the refugee definition is difficult in practice, it forms the essence of the admission process. US staff must be trained to make these decisions; indecisiveness must not be allowed to jeopardize refugees.

    As healthcare consumers increasingly turn to the World Wide Web (WWW) to obtain health information, it is imperative that health-related websites are user-centered. Websites are often developed without consideration of intended users' characteristics, literacy levels, preferences, and information goals resulting in user dissatisfaction, abandonment of the website, and ultimately the need for costly redesign. This paper provides a methodological review of a user-centered framework that incorporates best practices in literacy, information quality, and human-computer interface design and evaluation to guide the design and redesign process of a consumer health website. Following the description of the methods, a case analysis is presented, demonstrating the successful application of the model in the redesign of a consumer health information website with call center. Comparisons between the iterative revisions of the website showed improvements in usability, readability, and user satisfaction. PMID:21396486

    Full Text Available Background: Children are exposed to several environmental hazards with variable effects from mild to severe manifestations leading to death. The aim of this study is to study the pattern of Pediatric Intensive Care Unit (PICU admission due to environmental hazards and its mortality rate. Methods: This is a hospital-based study conducted during a 5 years period in Al-Madinah Al-Munwarah, Saudi Arabia. Results: Out of total PICU admissions, 9% were due to environmental hazards. Bronchial asthma which is triggered mostly by environmental factors, was the most common (35.3% followed by: trauma (27%, poisoning (15.3% and submersion injuries (9.7%. Males were significantly more exposed to environmental hazard than females (χ2= 13, p = 0.021. Statistical analysis showed a significant difference in the frequency of environmental hazards between summer and winter (χ2= 12, p = 0.033. Trauma, poisoning, submersion injuries, stings and bites were more in summer compared to winter. However, bronchial asthma had higher frequency in winter. The Median length of PICU stay ranges from 1.6 – 12.5 days depending on the type of hazard. Overall mortality rate was 8.8% with the highest rate among trauma followed by submersion injury patients with no fatality in drug ingestion or food poisoning. Conclusion: Environmental hazards represent a preventable major health problem with significant mortality and burden in health economics by long PICU stay and its sequel.

  10. Admission Control and Interference Management in Dynamic Spectrum Access Networks

    Directory of Open Access Journals (Sweden)

    Jorge Martinez-Bauset

    2010-01-01

    Full Text Available We study two important aspects to make dynamic spectrum access work in practice: the admission policy of secondary users (SUs to achieve a certain degree of quality of service and the management of the interference caused by SUs to primary users (PUs. In order to limit the forced termination probability of SUs, we evaluate the Fractional Guard Channel reservation scheme to give priority to spectrum handovers over new arrivals. We show that, contrary to what has been proposed, the throughput of SUs cannot be maximized by configuring the reservation parameter. We also study the interference caused by SUs to PUs. We propose and evaluate different mechanisms to reduce the interference, which are based on simple spectrum access algorithms for both PUs and SUs and channel repacking algorithms for SUs. Numerical results show that the reduction can be of one order of magnitude or more with respect to the random access case. Finally, we propose an adaptive admission control scheme that is able to limit simultaneously the forced termination probability of SUs and what we define as the probability of interference. Our scheme does not require any configuration parameters beyond the probability objectives. Besides, it is simple to implement and it can operate with any arrival process and distribution of the session duration.

    Full Text Available In Italy, the number of internists has grown by 10% since 1990 reaching 11,435 units, they manage 39,000 beds in 1060 Internal Medicine (IM wards. The Internists are expected to ensure a cost-effective management of poly-pathological and complex patients. A collaborative study between the Federation of Associations of Hospital Doctors on Internal Medicine (FADOI and the Consortium for Applied Health Economics Research (C.R.E.A. Sanità based on data from hospital discharge records has been conducted starting from November 2014. In this article the preliminary results are shown with focus on emergency admissions characteristics to contribute to define the role of hospital IM. Evaluation is performed comparing emergency and planned admissions, IM impact on hospital admissions, availability of community-based healthcare services, diagnosis-related groups (DRGs weight in IM and regional differences in managing hospital admissions with focus on IM department. In 2013 IM wards discharged 1,073,526 patients (16.18% of the total discharged by hospitals with a total economic value of 3,426,279.88 € (average DRG 3882.80 €, from 3682.19 to 4083.42. The average length of stay (LOS in IM was 9.3 days. IM covers 27% of admissions from Emergency Room. Determinants significantly affecting the emergency admissions are old age and comorbidities of the patients that also have a role in increasing LOS. 55% of Italian hospital admissions are emergency admissions. Hospitalization rates in emergency are systematically higher than those in election and the greatest differences are in the regions with inefficiently organized regional network. The role of the hospital IM appears central in the offer of beds to the emergency room by accepting 27% of urgent admissions. The increasing impact of IM on hospital management will put the internists as authoritative stakeholders in health policy.

  16. Cost and effects of different admission screening strategies to control the spread of methicillin-resistant Staphylococcus aureus.

    Directory of Open Access Journals (Sweden)

    Tanya Gurieva

    Full Text Available Nosocomial infection rates due to antibiotic-resistant bacteriae, e.g., methicillin-resistant Staphylococcus aureus (MRSA remain high in most countries. Screening for MRSA carriage followed by barrier precautions for documented carriers (so-called screen and isolate (S&I has been successful in some, but not all settings. Moreover, different strategies have been proposed, but comparative studies determining their relative effects and costs are not available. We, therefore, used a mathematical model to evaluate the effect and costs of different S&I strategies and to identify the critical parameters for this outcome. The dynamic stochastic simulation model consists of 3 hospitals with general wards and intensive care units (ICUs and incorporates readmission of carriers of MRSA. Patient flow between ICUs and wards was based on real observations. Baseline prevalence of MRSA was set at 20% in ICUs and hospital-wide at 5%; ranges of costs and infection rates were based on published data. Four S&I strategies were compared to a do-nothing scenario: S&I of previously documented carriers ("flagged" patients; S&I of flagged patients and ICU admissions; S&I of flagged and group of "frequent" patients; S&I of all hospital admissions (universal screening. Evaluated levels of efficacy of S&I were 10%, 25%, 50% and 100%. Our model predicts that S&I of flagged and S&I of flagged and ICU patients are the most cost-saving strategies with fastest return of investment. For low isolation efficacy universal screening and S&I of flagged and "frequent" patients may never become cost-saving. Universal screening is predicted to prevent hardly more infections than S&I of flagged and "frequent" patients, albeit at higher costs. Whether an intervention becomes cost-saving within 10 years critically depends on costs per infection in ICU, costs of screening and isolation efficacy.

  18. Admissibility analysis for linear singular systems with time-varying delays via neutral system approach.

    Science.gov (United States)

    Liu, Zhou-Yang; Lin, Chong; Chen, Bing

    2016-03-01

    This paper studies the admissibility problem for a class of linear singular systems with time-varying delays. In order to highlight the relations between the delay and the state, the singular system is transformed into a neutral form. Then, an appropriate type of Lyapunov-Krasovskii functionals is proposed to develop a delay-derivative-dependent admissibility condition in terms of linear matrix inequalities. The derivation combines the Wirtinger-based inequality and reciprocally convex combination method. The present criterion is also for the stability test of retarded and neutral systems with time-varying delays. Some examples are provided to illustrate the effectiveness and the benefits of the proposed method.

    2015-11-01

    This paper addresses the problem of automated detection of Z-calls emitted by Antarctic blue whales (B. m. intermedia). The proposed solution is based on a subspace detector of sigmoidal-frequency signals with unknown time-varying amplitude. This detection strategy takes into account frequency variations of blue whale calls as well as the presence of other transient sounds that can interfere with Z-calls (such as airguns or other whale calls). The proposed method has been tested on more than 105 h of acoustic data containing about 2200 Z-calls (as found by an experienced human operator). This method is shown to have a correct-detection rate of up to more than 15% better than the extensible bioacoustic tool package, a spectrogram-based correlation detector commonly used to study blue whales. Because the proposed method relies on subspace detection, it does not suffer from some drawbacks of correlation-based detectors. In particular, it does not require the choice of an a priori fixed and subjective template. The analytic expression of the detection performance is also derived, which provides crucial information for higher level analyses such as animal density estimation from acoustic data. Finally, the detection threshold automatically adapts to the soundscape in order not to violate a user-specified false alarm rate. PMID:26627784

    Geologic carbon sequestration is a means to mitigate the increasing atmospheric concentration of carbon dioxide (CO2) by capturing the CO2 at a source such as a power generation facility and storing the captured CO2 in geologic formations. Many technologic advances will need to occur for successful carbon sequestration including near surface monitoring tools and techniques to ensure site integrity and public safety. Researchers at Montana State University (MSU) are developing a scalable fiber sensor array in a call/return configuration for monitoring near sub-surface CO2 concentrations. The low cost fiber sensor array being developed at MSU for sub-surface CO2 detection for monitoring carbon sequestration sites will utilize a series of fiber probes connected to a two detectors and a 1 x N fiber switch that can direct the light to one of N fiber probes. The fiber sensor array will utilize a single tunable distributed feedback (DFB) diode laser with a center wavelength of 2.004 μm to access CO2 absorption features. The output from the DFB laser is incident on an inline fiber splitter that directs part of the light to a reference detector while the remaining light is directed to a fiber probe where the laser light interacts with the CO2. The light from the fiber probe is directed back through the switch and is incident on a transmission detector. The transmission as a function of wavelength is measured and a CO2 concentration is calculated. The fiber sensor array can easily be reconfigured by simply moving the fiber probes. Low cost is achieved by using inexpensive passive components in the fiber probes while limiting the number of the more expensive components including the DFB laser, the two detectors, and the single fiber switch. The fiber sensor was tested over a thirty day period at the Zero Emission Research Technology (ZERT) facility that was developed for testing surface and near surface carbon sequestration monitoring instrumentation using a controlled

    Blunt trauma victims and selected patients with penetrating trauma are systematically investigated after resuscitation and hemodynamic stabilization with cross-sectional imaging. Computed tomography is a good predictor of the need for hemostatic arteriographic embolization, based on contrast medium extravasation observed on CT. In centers admitting polytrauma patients, the CT and angiography units should be installed together within the emergency environment. Trauma-dedicated interventional radiologists should be on call for optimal patient management. Posttraumatic retroperitoneal and pelvic bleeding is a primary indication for angiographic hemostasis, together with orthopedic fixation of pelvic bone fractures. Angiography should be carried out rapidly, before the patient decompensates for considerable blood loss. In patients with visceral bleeding, arterial embolization can obviate primary surgery or potentializes surgical intervention and contributes to changing hierarchy of injuries to be treated surgically. Failure to achieve primary hemostasis may occur according to the type of specific organ injury and coagulation and metabolic parameters of the patient. Postembolization complications are few and are usually non-life-threatening and rarely carry definitive sequelae. (orig.)

    People in modern societies form different social networks through numerous means of communication. These communication networks reflect different aspects of human's societal structure. The billing records of calls among mobile phone users enable us to construct a directed calling network (DCN) and its Bonferroni network (SVDCN) in which the preferential communications are statistically validated. Here we perform a comparative investigation of the cliques of the original DCN and its SVDCN constructed from the calling records of more than nine million individuals in Shanghai over a period of 110 days. We find that the statistical properties of the cliques of the two calling networks are qualitatively similar and the clique members in the DCN and the SVDCN exhibit idiosyncratic behaviors quantitatively. Members in large cliques are found to be spatially close to each other. Based on the clique degree profile of each mobile phone user, the most active users in the two calling networks can be classified in to several groups. The users in different groups are found to have different calling behaviors. Our study unveils interesting communication behaviors among mobile phone users that are densely connected to each other.

    Full Text Available Aim. The aim of this retrospective study was to determine mean admission time after calls, resuscitation success rate, and determine the rate of medical emergency team (MET calls of clinics in hospital by assessing the incoming calls to MET at intensive care unit. Methods. This study was conducted by collecting emergency call forms of 147 patients. The data including age, gender, medical diagnosis, the name of the caller department, cause of call, occurrence time, call time, attending time, medical care termination time and the outcomes were extracted from the forms or patient files. Event declaration time was accepted as minute time difference between occurrence time and call time. Duration of admission was accepted as minute time difference between call times and attending time. Duration of resuscitation was accepted as minute time difference between attending time and medical care termination time. Results. Mean event declaration time was 3.3 ± 3.0 minutes. Mean duration of admission was 3.7 ± 1.6 minutes. Mean duration of resuscitation was 20.5 ± 12.7 minutes. The resuscitation of 84 patients (63.6% was successful while 48 patients (36.4% died at the end of resuscitation. It was found that the patients with a result of successful resuscitation were significantly younger and their duration of resuscitation was significantly shorter. Conclusion. We indicate that MET system is an essential part of in-hospital emergency medical care system. We suggest that a blue code call system should be established by intensive care unit members and announced to all hospital staff.

    Namibia officially became the 136th ¿member state¿ of the International Labour Office (ILO) on October 3, 1978. At that time Namibia was politically dependent on South Africa and lived under apartheid. This stood in contradiction to international law, given that since October 1966 the UN General Assembly had terminated the Republic of South Africa's mandate over the territory. In 1967 it had entrusted its official administration to the UN Council for Namibia, which requested Namibia's admission to the ILO as a full member. Namibia met all the criteria required of a state: an established population and territory, a stable and internationally recognized legal structure, together with the capacity to enter into relations with other states. Namibia was recognized by the Conference as the de-facto authentic government through an election in which 368 voted in favor of Namibia with no oppositions and 50 abstentions.

    2016-01-01

    We give new proofs of the rationality of the N=1 superconformal minimal model vertex operator superalgebras and of the classification of their modules in both the Neveu-Schwarz and Ramond sectors. For this, we combine the standard free field realisation with the theory of Jack symmetric functions. A key role is played by Jack symmetric polynomials with a certain negative parameter that are labelled by admissible partitions. These polynomials are shown to describe free fermion correlators, suitably dressed by a symmetrising factor. The classification proofs concentrate on explicitly identifying Zhu's algebra and its twisted analogue. Interestingly, these identifications do not use an explicit expression for the non-trivial vacuum singular vector. While the latter is known to be expressible in terms of an Uglov symmetric polynomial or a linear combination of Jack superpolynomials, it turns out that standard Jack polynomials (and functions) suffice to prove the classification.

    2011-01-01

    A service provisioning system is examined, where a number of servers are used to offer different types of services to paying customers. A customer is charged for the execution of a stream of jobs; the number of jobs in the stream and the rate of their submission is specified. On the other hand, the provider promises a certain quality of service (QoS), measured by the average waiting time of the jobs in the stream. A penalty is paid if the agreed QoS requirement is not met. The objective is to maximize the total average revenue per unit time. Dynamic policies for making server allocation and stream admission decisions are introduced and evaluated. The results of several simulations are described.

  14. Temperature effects on hospital admissions for kidney morbidity in Taiwan

    International Nuclear Information System (INIS)

    Objective: This study aimed to associate hospital admissions of kidney diseases with extreme temperature and prolonged heat/cold events in 7 regions of Taiwan. Methods: Age-specific (10, O3, and NO2) and potential confounders. Results: We observed a V or J-shape association between daily average temperatures and the RR estimates for hospital admissions of kidney diseases in Taiwan. The lowest risk for hospital admissions of kidney diseases was found at around 25 °C, and risk increased as temperatures deviated from 25 °C. The pooled cumulative 8-day RR for all ages of population of the 7 study areas were 1.10 (95% confidence interval (CI): 1.01, 1.19) at 18 °C and 1.45 (95% CI: 1.27, 1.64) at 30 °C. High temperature has more profound influence on hospital admission of kidney diseases than low temperature. Temperature risks for hospital admissions were similar between younger (< 65 years) and elderly (65 + years) population. This study observed no significant effects of prolonged heat extremes on hospital admissions of kidney diseases. Conclusions: The heat effect for kidney morbidities leading to hospital admission was more significant than that of the cold temperature. This study did not find the age-dependent relative risks for temperature associating with hospital admissions of kidney diseases. - Highlights: ► V or J-shaped association was observed between daily temperatures and hospital admissions for renal diseases in Taiwan. ► The pooled relative risks accounting for 8 days of lag for the 7 study areas were 1.1 at 18 °C and 1.46 at 30 °C. ► There is no difference of the relative risk estimates for hospital admissions between younger and elderly population. ► We found significant protective effects of hospital admissions for prolonged cold extremes, but not for heat extremes

    The re-hospitalization rate of homecare patients within 60 days of hospital discharge is 30%. Enhanced care planning based on better information may reduce this rate. However, very little is known about the homecare admission and care planning processes. The research team collected data during observations of three nursing visits to admit homecare patients in Camden NJ, and conducted thematic content analysis on these data. Human factors methods helped to identify nurse decision-making related to selection of the plan of care problems, non-nursing resources, and the nursing visit pattern. They identified how the electronic health record (EHR) assisted the nurse in visit pattern frequency decisions. Major themes that emerged included reduced efficiency due to use of redundant intra-team communication methods to augment EHR documentation, redundant documentation, and workarounds and reorganization of clinical workflow.

    Most of malicious behaviours of Android applications come from abuses of system resources,and the resources usage information serves to fast analysing the malicious behaviours.However,due to the characteristic of Android system using permission mechanism in its management,current system call-based method does not effective in monitoring Android applications resource usage.Aiming at this problem, we design and implement SysTracker,which is a technique based on system call and assisted with mapping relationship between API and system call to monitor the resource usage in Android applications.By intercepting and capturing the system call in Android applications and analysing the related information called by the system,the SysTracker restores the special system call sequence to corresponding API call with the help of mapping relation of API and system call,so as to recognise the resource usage information from the applications.Large-scale applications tests show that the recognition rate of SysTracker on API call reaches up to 99.2%,meanwhile,it is demonstrated by the analyses of a couple of applications that the SysTracker can intuitively reflect the situation of resources usage by the applications for quick identifying the malicious behaviours of the application.%安卓恶意应用行为大多源于对系统资源的非法使用,资源使用信息将有助于快速地分析恶意行为。然而,由于安卓系统使用权限机制对资源进行管理的特性,现有的基于系统调用监测安卓应用资源使用的方法并不行之有效。针对该问题,设计并实现了SysTracker:一种采用系统调用辅以API-系统调用映射关系来监测安卓应用资源使用的技术。SysTracker通过截获安卓应用程序中的系统调用,并对系统调用的相关信息进行解析,借助API-系统调用映射关系将特殊的系统调用序列还原为相应的API调用,从而识别出应用程序中资源使用信息。大规模的应

    2011-10-01

    The 2001 Mental Health Act introduced in 2006, changed how a patient is admitted involuntarily to a psychiatric unit. This paper reports on a national survey of general practitioners\\' experience implementing the Act. Five hundred and sixty eight (568) GPs completed the survey. Twenty five percent (25%) of respondants had not used it. When used, twenty four percent (24%) report that it takes seven hours or more to complete an admission. Fifty percent (50%) of respondents are confident to complete the necessary paperwork. Overall GPs are dissatisfied with arrangements for transport of patients (mean Likert score 3.5), primarily due to the time delay. GPs believe this places risk on the patient, family and GP. Only thirty-three percent (33%) of respondents feel that the Mental Health Act has improved the patient, GP and family experience of involuntary admission.

Both legislation and public opinion implicitly require nonacademic criteria and personality traits to be included into the selection criteria (motivation, identification, avoidance of misconceptions. Since interviews appear to be not suitable for the high number of applicants the Medical Faculty of the Johann Wolfgang Goethe University in Frankfurt/Main has developed a questionnaire covering extracurricular achievements. This questionnaire has be answered by first year students of the JWG university Frankfurt and the Medical University Innsbruck at the begin of the winter term 2005/2006. Contrary to initial expectations, only 15% of the students stated specific job experience in a medically related field (emergency service, nurse or similar occupations, whereas more than 60% indicated to play at least one instrument and/or being engaged in sports activities. The summary of these self experiences indicate that only a minority of admitted students have medically related experience to a larger degree.

    This article presents some of the most salient qualitative results from a larger program evaluation of pregnant and parenting adolescents who participated in a community-based doula program. Using grounded theory analysis, seven problem-solving strategies emerged that doulas apply in helping pregnant and parenting adolescents navigate multiple social and health settings that often serve as barriers to positive maternal- and child-health outcomes. The ethnographic findings of this study suggest that the doulas provide valuable assistance to pregnant and parenting adolescents by addressing social-psychological issues and socio-economic disparities. "Diverse role-taking" results in doulas helping pregnant adolescents navigate more successfully through fragmented social and health service systems that are less supportive of low-income adolescents, who are often perceived to be draining scarce resources. The findings have implications for the roles of community-based doulas assigned to low-income adolescents of color seeking to overcome obstacles and attain better educational and economic opportunities.

    Despite a growing consensus regarding the value of inquiry-based learning (IBL) for students' learning and engagement in the science classroom, the implementation of such practices continues to be a challenge. If science teachers are to use IBL to develop students' inquiry practices and encourage them to think and act as scientists, a better understanding of factors that influence their attitudes towards scientific research and scientists' practices is very much needed. Within this context there is a need to re-examine the science teachers' views of scientists and the cultural factors that might have an impact on teachers' views and pedagogical practices. A diverse group of Egyptian science teachers took part in a quantitative-qualitative study using a questionnaire and in-depth interviews to explore their views of scientists and scientific research, and to understand how they negotiated their views of scientists and scientific research in the classroom, and how these views informed their practices of using inquiry in the classroom. The findings highlighted how the teachers' cultural beliefs and views of scientists and scientific research had constructed idiosyncratic pedagogical views and practices. The study suggested implications for further research and argued for teacher professional development based on partnerships with scientists.

    Background Medication reconciliation has been mandated by the Irish government at transfer of care. Research is needed to determine the contribution of clinical pharmacists to the process. Objective To describe the contribution of emergency department based clinical pharmacists to admission medication reconciliation in Ireland. Main Outcome Measure Frequency of clinical pharmacist\\'s activities. Setting Two public university teaching hospitals. Methodology Adults admitted via the accident and emergency department, from a non-acute setting, reporting the use of at least three regular prescription medications, were eligible for inclusion. Medication reconciliation was provided by clinical pharmacists to randomly-selected patients within 24-hours of admission. This process includes collecting a gold-standard pre-admission medication list, checking this against the admission prescription and communicating any changes. A discrepancy was defined as any difference between the gold-standard pre-admission medication list and the admission prescription. Discrepancies were communicated to the clinician in the patient\\'s healthcare record. Potentially harmful discrepancies were also communicated verbally. Pharmacist activities and unintentional discrepancies, both resolved and unresolved at 48-hours were measured. Unresolved discrepancies were confirmed verbally by the team as intentional or unintentional. A reliable and validated tool was used to assess clinical significance by medical consultants, clinical pharmacists, community pharmacists and general practitioners. Results In total, 134 patients, involving 1,556 medications, were included in the survey. Over 97 % of patients (involving 59 % of medications) experienced a medication change on admission. Over 90 % of patients (involving 29 % of medications) warranted clinical pharmacy input to determine whether such changes were intentional or unintentional. There were 447 interventions by the clinical pharmacist regarding

    Understanding the use of patient monitoring systems in emergency and acute facilities may help to identify reasons for failure to identify risk patients in these settings. Hence, we investigate factors related to the utilization of automated monitoring for patients admitted to an acute admission...... one measurement were analyzed using quantile regression by looking at the impact of distance from nursing office, number of concurrent patients, wing type (medical/surgical), age, sex, comorbidities, and severity conditioned on how much patients were monitored during their admissions. We registered 11......,848 admissions, of which we were able to link patient monitor readings to 3149 (26.6 %) with 50 % being monitored <1.4 % of total admission time. Distance from nursing office had little influence on patients monitored <10 % of their admission time. But for other patients, being positioned further away from the...

    Full Text Available Abstract Background The continued increase in hospital admissions is a significant and complex issue facing health services. There is little research exploring patient perspectives or examining individual admissions among patients with frequent admissions for chronic ambulatory care sensitive (ACS conditions. This paper aims to describe characteristics of older, rural patients frequently admitted with ACS conditions and identify factors associated with their admissions from the patient perspective. Methods Patients aged 65+ resident in North Coast NSW with three or more admissions for selected ACS chronic conditions within a 12 month period, were invited to participate in a postal survey and follow up telephone call. Survey and telephone data were linked to admission and health service program data. Descriptive statistics were generated for survey respondents; logistic regression models developed to compare characteristics of patients with 3 or with 4+ admissions; and comparisons made between survey respondents and non-respondents. Results Survey respondents (n=102 had a mean age of 77.1 years (range 66–95 years, and a mean of 4.1 admissions within 12 months; 49% had at least three chronic conditions; the majority had low socioeconomic status; one in five (22% reported some difficulty affording their medication; and 35% lived alone. The majority reported psychological distress with 31% having moderate or severe psychological distress. While all had a GP, only 38% reported having a written GP care plan. 22% of those who needed regular help with daily tasks did not have a close friend or relative who regularly cared for them. Factors independently associated with more frequent (n=4+ relative to less frequent (n=3 admissions included having congestive heart failure (p=0.003, higher social isolation scores (p=0.040 and higher Charlson Comorbidity Index scores (p=0.049. Most respondents (61% felt there was nothing that could have avoided their most

    Acute kidney injury (AKI) is a common problem, especially in critically ill patients. In Critical Care, Kolhe and colleagues report that 6.3% of 276,731 patients in 170 intensive care units (ICUs) in the UK had evidence of severe AKI within the first 24 hours of admission to ICU. ICU and hospital mortality as well as length of stay in hospital were significantly increased. In light of this serious burden on individuals and the health system in general, the following commentary discusses the current state of knowledge of AKI in ICU and calls for more attention to preventive strategies.

    Full Text Available Next generation Passive Optical Network (PONtechnology has been evolving to consolidate the metro andaccess networks in order to offer enhanced capacity, highsplit ratio and reduced deployment cost per subscriber.However, transmission of the signals to long distances up to100km leads to increased propagation delay whereas highsplit ratio may lead to long cycle times resulting in largequeue occupancies and long packet delays. In this article, wepresent a delay-constrained admission control mechanismand adapt this scheme to our previously proposed bandwidthallocation technique, namely Periodic GATE Optimization(PGO. We call this new scheme Delay-Constrained PeriodicGATE Optimization (DC-PGO. DC-PGO is designed to runfor multiple service classes as it inherits the advantages ofPGO by periodically building and solving an ILP formulationat the OLT in order to obtain the appropriate creditvalues for the overloaded ONUs. At the ONU side, DCPGOruns an admission control scheme before pushing thearriving packets in the sub-queues. The admission controlscheme uses statistical information consisting of the localdata at the ONU and the previously received GATE messagesfrom the OLT. Through simulations, we show that DC-PGOenhances the performance of multi-threaded polling in longreachEthernet PON when packets of differentiated serviceclasses arrive with pre-specified delay requirements.

In this mechanism, the bits of the subcarrier of OFDM in the station are allocated to obtain the maximum channel capacity subjected to the maximum power at first and the bit rate is transmitted to the medium access control layer at the same time. By means of that,a dynamic reservation of the bandwidth was presented based on the distributed measurement, which a-dapts tb the characteristics of the channel and the service. And an estimation of the surplus factor by center control half-based on model was presented, which overcomes the un-accuracy resulted by directed measuring and locality resulted by distributed estimation. The relationship between the service's parameters and the collision probability was obtained and the double admission criteria of the bandwidth and the collision probability was suggested to support the multiple QoS such as bandwidth and delay as well as error ratio of the frame. All above suggestions structure an adaptive admission control from the upper layer to the lower layer

    2003-11-01

    Nosocomial clustering with transmission to health care workers, patients and visitors is a prominent feature of severe acute respiratory syndrome (SARS). Hospital outbreaks of SARS typically occurred within the first week after admission of the very first SARS cases when the disease was not recognized and before isolation measures were implemented. In the majority of nosocomial infections, there was a history of close contact with a SARS patient, and transmission occurred via large droplets, direct contact with infectious material or by contact with fomites contaminated by infectious material. In a few instances, potential airborne transmission was reported in association with endotracheal intubation, nebulised medications and non-invasive positive pressure ventilation of SARS patients. In all SARS-affected countries, nosocomial transmission of the disease was effectively halted by enforcement of routine standard, contact and droplet precautions in all clinical areas and additional airborne precautions in the high-risk areas. In Hong Kong, where there are few private rooms for patient isolation, some hospitals have obtained good outcome by having designated SARS teams and separate wards for patient triage, confirmed SARS cases and step-down of patients in whom SARS had been ruled out. In conclusion, SARS represents one of the new challenges for those who are involved in hospital infection control. As SARS might re-emerge, all hospitals should take advantage of the current SARS-free interval to review their infection control programmes, alert mechanisms, response capability and to repair any identified inadequacies.

If, in addition, all the maps $\\mathbb{M}(T,M)\\rightarrow \\mathbf{Set}(1,U(M))$ induced by the functor $UH$ are surjections, where $T$ and 1 are respectively terminal objects in $\\mathbb{C}$ and $\\mathbf{Set}$, for every object $M$ in the full subcategory $\\mathbb{M}$, then it is true that: the reflection $H\\vdash I$ is semi-left-exact (admissible in the sense of categorical Galois theory) if and only if its connected components are "connected"; it has stable units if and only if any finite product of connected components is "connected". Where the meaning of "connected" is the usual in categorical Galois theory, and the definition of connected component with respect to the ground structure wil...

    1997-06-01

    A calling is a deep desire to devote oneself to serving people according to the high values of the task or profession. The aim of this study is to clarify the relationship between a calling experience and professional knowledge, nursing action and motivation. The data were collected from all the registered nurses (n = 179) at five hospitals. The response was 70%. The nurses who were committed to their profession and experienced their job as a calling, had a good knowledge about the ill feeling and maladjustment of their patients and were also good sources of support for their patients. They understood the importance of family ties and offered support to their patients' families. They were aware of the needs of dying patients and their concern with spiritual questions, and satisfied these needs well. It was characteristic for them to collaborate closely within a team, to experience the content of their work as enriching and to possess proficient professional abilities. They were therefore excellent in supporting both the individual patient and his or her family. They had a deep understanding of the whole process of patient care. According to these results the calling experience is not in conflict with professional principles. PMID:9181405

    2014-12-01

    Numerous studies have reported that admission rates in patients with affective disorders are subject to seasonal variation. Notwithstanding, there has been limited evaluation of the degree to which changeable daily meteorological patterns influence affective disorder admission rates. A handful of small studies have alluded to a potential link between psychiatric admission rates and meteorological variables such as environmental temperature (heat waves in particular), wind direction and sunshine. We used the Kruskal-Wallis test, ARIMA and time-series regression analyses to examine whether daily meteorological variables—namely wind speed and direction, barometric pressure, rainfall, hours of sunshine, sunlight radiation and temperature—influence admission rates for mania and depression across 12 regions in Ireland over a 31-year period. Although we found some very weak but interesting trends for barometric pressure in relation to mania admissions, daily meteorological patterns did not appear to affect hospital admissions overall for mania or depression. Our results do not support the small number of papers to date that suggest a link between daily meteorological variables and affective disorder admissions. Further study is needed.

    Full Text Available Abstract Background Personality disorders affect a substantial proportion of the population. It is unclear, however, whether the burden of personality disorders on modern mental health services has been increasing. To fill this gap, we analyzed trends in admissions for personality disorders in Italy from 1988 to 1998. Methods We used the yearly data from the Italian Central Institute of Statistics to analyse trends in the total number of admissions for personality disorders and in the total number of first admissions for personality disorders. Results The absolute number of admissions for personality disorders almost trebled from 1988 to 1998, as well as the proportion of all psychiatric admissions that were for personality disorders. Whilst there has been a marked increase in the absolute number of first admissions, the proportion of all first psychiatric admissions that were for personality disorders showed a steady but modest increase, from 5.7% to 7.6%. Conclusion In Italy, the burden of personality disorders on modern mental health services has been increasing. In terms of public health, these findings highlight the urgent need of developing policies to tackle the increasing demand of care of this difficult-to-treat patient population.

    2005-02-01

    Full Text Available Abstract Background Information on the extent of postpartum maternal morbidity in developing countries is extremely limited. In many settings, data from hospital-based studies is hard to interpret because of the small proportion of women that have access to medical care. However, in those areas with good uptake of health care, the measurement of the type and incidence of complications severe enough to require hospitalisation may provide useful baseline information on the acute and severe morbidity that women experience in the early weeks following childbirth. An analysis of health services data from Lusaka, Zambia, is presented. Methods Six-month retrospective review of hospital registers and 4-week cross-sectional study with prospective identification of postpartum admissions. Results Both parts of the study identified puerperal sepsis and malaria as, respectively, the leading direct and indirect causes of postpartum morbidity requiring hospital admission. Puerperal sepsis accounted for 34.8% of 365 postpartum admissions in the 6-month period. Malaria and pneumonia together accounted for one-fifth of all postpartum admissions (14.5% & 6% respectively. At least 1.7% of the postpartum population in Lusaka will require hospital-level care for a maternal morbidity. Conclusions In developing country urban settings with high public health care usage, meticulous review of hospital registers can provide baseline information on the burden of moderate-to-severe postpartum morbidity.

    Full Text Available OBJECTIVE: To analyze the impact of intra-urban atmospheric conditions on circulatory and respiratory diseases in elder adults. METHODS: Cross-sectional study based on data from 33,212 hospital admissions in adults over 60 years in the city of São Paulo, southeastern Brazil, from 2003 to 2007. The association between atmospheric variables from Congonhas airport and bioclimatic index, Physiological Equivalent Temperature, was analyzed according to the district's socioenvironmental profile. Descriptive statistical analysis and regression models were used. RESULTS: There was an increase in hospital admissions due to circulatory diseases as average and lowest temperatures decreased. The likelihood of being admitted to the hospital increased by 12% with 1ºC decrease in the bioclimatic index and with 1ºC increase in the highest temperatures in the group with lower socioenvironmental conditions. The risk of admission due to respiratory diseases increased with inadequate air quality in districts with higher socioenvironmental conditions. CONCLUSIONS: The associations between morbidity and climate variables and the comfort index varied in different groups and diseases. Lower and higher temperatures increased the risk of hospital admission in the elderly. Districts with lower socioenvironmental conditions showed greater adverse health impacts.

  2. A Contrastive Genre Analysis of Chinese and American University Ad-mission Brochures

    2015-01-01

    This study mainly uses the move and step analysis to conduct a contrastive genre analysis on the selected 20 Chinese ad⁃mission brochures (CABs) and 20 American admission brochures (AABs). Differences in moves, move sequences and step arrange⁃ments have revealed themselves in this comparison. Firstly, Chinese university admission brochures cast more focus on basic infor⁃mation about the university, the application procedure and admission criteria, while American universities, besides offering such in⁃formation, also emphasize the promotional function of the admission brochures. They use appealing and creative moves to commer⁃cially‘sell’advantages of the university to the potential applicants. Secondly, based on Kress&van Leeuwen’s visual grammar symbolic meaning, images and colors in admission brochures are also explored and analyzed as language. For one thing, after count⁃ing the frequency of the four categories of images, namely portrait, campus scenery, campus life pictures and graphs, it is found that, compared with CABs, AABs have a highly more obvious tendency in using images. The images are used as an effective tool to increase the sense of credibility, identity-recognition, attract reader’s attention, and help understanding, making the facts and in⁃formation more intuitive. For another thing, the main colors used in the brochures are yet another noticeable feature. Especially in American brochures, universities tend to use their‘traditional colors’in the brochure to achieve a sense of consistency. Some Chi⁃nese brochures also follow this promotional strategy, yet a large percentage of them do not use any recognizable colors other than the printed black and white. Based on these differences, suggestions are put forward from perspectives including choice of moves and steps to improve the quality of CABs, hopefully raising their acceptance in the international level.

    Emergency department (ED) practices are traditionally profiled in terms of their patient encounters. Such evaluations reflect a preponderance of outpatient visits while crediting income from admitted patients to traditional hospital-based services. This study evaluates the contribution of ED admissions to inpatient hospital revenue. The study was set at an urban tertiary care community hospital with university affiliation. Information referable to ED patients was collected from the hospital's Universal Billing Code (UB-92)-based patient information warehouse. Data fields referable to hospital charges, insurance type, and disposition were used for analysis of a 1-year period from September 1, 1998 to August 31, 1999. Statistical analysis was through chi square and ANOVA. During the study period 33,174 patients were treated in the ED with 6,671 (20%) admitted to inpatient services. Total hospital charges for all ED patients during this time were $107 million dollars with $9.1 million (8.5%) generated from discharged patients and $98.0 million (91.5%) from admitted ED patients (P revenue for inpatient services for the study period was $288 million of which 34% was contributed from admitted ED patients. ED services represent a major source of inpatient hospital revenue. The recognition of the ED's potential in this area may be lost if income from patients admitted through the ED is credited to traditional hospital-based services.

  7. Ultrasound call detection in capybara

    Full Text Available The vocal repertoire of some animal species has been considered a non-invasive tool to predict distress reactivity. In rats ultrasound emissions were reported as distress indicator. Capybaras[ vocal repertoire was reported recently and seems to have ultrasound calls, but this has not yet been confirmed. Thus, in order to check if a poor state of welfare was linked to ultrasound calls in the capybara vocal repertoire, the aim of this study was to track the presence of ultrasound emissions in 11 animals under three conditions: 1 unrestrained; 2 intermediately restrained, and 3 highly restrained. The ultrasound track identified frequencies in the range of 31.8±3.5 kHz in adults and 33.2±8.5 kHz in juveniles. These ultrasound frequencies occurred only when animals were highly restrained, physically restrained or injured during handling. We concluded that these calls with ultrasound components are related to pain and restraint because they did not occur when animals were free of restraint. Thus we suggest that this vocalization may be used as an additional tool to assess capybaras[ welfare.

    Full Text Available Abstract Smoking and withdrawal from smoking complicates the assessment and treatment of mental illness. We aimed to establish whether psychiatric inpatients smoke different amounts after admission than beforehand and, if so, to find out why. Forty-three inpatients on a working age adult psychiatry ward completed self-report questionnaires about smoking habits. Those who smoked a different amount after admission had a follow-up interview to find out why they thought this had occurred. The interview incorporated qualitative and quantitative aspects which were analysed accordingly. Fifty-six percent of participants were smokers before admission, rising to 70% afterwards. Of the smokers, 17% smoked less after admission, and 63% smoked more. The average number of cigarettes smoked per person per day increased from five to thirteen. The main reasons for smoking more were boredom, stress and the wish to socialise.

  1. Modular Design of Call Control Layer in Telephony Software

    Directory of Open Access Journals (Sweden)

    Ilija Basicevic

    2011-01-01

    Full Text Available An important property of a telephony system is the call control model on which it is based. It is noted that many call control models in the past, especially those in PSTN/ISDN networks follow centralized model. For such a model, typical is significant coupling of modules belonging to different services with the basic call control module which is aware of all active telephony features in the system. Although sometimes based on distributed model, VoIP call control models still manifest some of the listed problems of their predecessors. In this paper we present a fully distributed model which exhibits minimal coupling of modules belonging to different services and a simple basic call control module. The model is based on taxonomies of call control services which are presented in the paper. Also, the implementation of several typical services is described.

    2007-01-01

    A novel bandwidth allocation strategy and a connection admission control technique are proposed to improve the utilization of network resource and provide the network with better quality of service (QoS) guarantees in multimedia low earth orbit (LEO) satellite networks. Our connection admission control scheme, we call the probability based dynamic channel reservation strategy (PDR), dynamically reserves bandwidth for real-time services based on their handoff probability. And the reserved bandwidth for real-time handoff connection can also be used by new connections under a certain probability determined by the mobility characteristics and bandwidth usage of the system. Simulation results show that our scheme not only lowers the call dropping probability (CDP) for Class I real-time service but also maintains the call blocking probability (CBP) to certain degree. Consequently, the scheme can offer very low CDP for real-time connections while keeping resource utilization high.

  9. Daily diurnal variation in admissions for ruptured abdominal aortic aneurysms.

    LENUS (Irish Health Repository)

    Killeen, Shane

    2012-02-03

    BACKGROUND: Many vascular events, such as myocardial infarction and cerebrovascular accident, demonstrate a circadian pattern of presentation. Blood pressure is intimately related to these pathologies and is the one physiological variable consistently associated with abdominal aortic aneurysm rupture. It also demonstrates a diurnal variation. The purpose of this study was to determine if rupture of an abdominal aortic aneurysm (RAAA) exhibits a diurnal variation. METHODS: A retrospective cohort-based study was performed to determine the timing of presentation of RAAA to the vascular unit of Cork University Hospital over a 15-year period. Time of admission, symptom onset, and co-morbidities such as hypertension were noted. Fournier\\'s analysis and chi-squared analysis were performed. To ameliorate possible confounding factors, patients admitted with perforated peptic ulcers were examined in the same manner. RESULTS: A total of 148 cases of RAAA were identified, with a male preponderance (71.7% [124] male versus 29.3% [44] female patients) and a mean age of 74.4 +\\/- 7.2 years at presentation. 70.9% (105) were known to have hypertension, 52.2% (77) were current smokers, and 46.8% (69) were being treated for chronic obstructive airway disease (COAD). Time of symptom onset was recorded in 88.5% (131) of patients. There was a marked early morning peak in RAAA admissions, with the highest number of RAAA being admitted between 08.00 and 09.59. A second, smaller peak was observed at 14.00-15.59. These findings were suggestive of diurnal variation. [chi(2) =16.75, p < 0.003]. Some 40% (59) of patients were admitted between 00.00 and 06.00, an incidence significantly higher than for other time periods (06.00-12.00, 12.00-18.00, and 18.00-24.00) [chi(2) = 18.72; df = 3; p < 0.0003]. A significantly higher number of patients admitted between 00.00 and 06.00 were known hypertensives (chi(2) = 7.94; p < 0.05). CONCLUSIONS: The findings of this study suggest a distinct

  11. Forecasting paediatric malaria admissions on the Kenya Coast using rainfall

    Directory of Open Access Journals (Sweden)

    Stella Wanjugu Karuri

    2016-02-01

    Full Text Available Background: Malaria is a vector-borne disease which, despite recent scaled-up efforts to achieve control in Africa, continues to pose a major threat to child survival. The disease is caused by the protozoan parasite Plasmodium and requires mosquitoes and humans for transmission. Rainfall is a major factor in seasonal and secular patterns of malaria transmission along the East African coast. Objective: The goal of the study was to develop a model to reliably forecast incidences of paediatric malaria admissions to Kilifi District Hospital (KDH. Design: In this article, we apply several statistical models to look at the temporal association between monthly paediatric malaria hospital admissions, rainfall, and Indian Ocean sea surface temperatures. Trend and seasonally adjusted, marginal and multivariate, time-series models for hospital admissions were applied to a unique data set to examine the role of climate, seasonality, and long-term anomalies in predicting malaria hospital admission rates and whether these might become more or less predictable with increasing vector control. Results: The proportion of paediatric admissions to KDH that have malaria as a cause of admission can be forecast by a model which depends on the proportion of malaria admissions in the previous 2 months. This model is improved by incorporating either the previous month's Indian Ocean Dipole information or the previous 2 months’ rainfall. Conclusions: Surveillance data can help build time-series prediction models which can be used to anticipate seasonal variations in clinical burdens of malaria in stable transmission areas and aid the timing of malaria vector control.

    Sørup, Signe; Stensballe, Lone G; Krause, Tyra G; Aaby, Peter; Benn, Christine S; Ravn, Henrik

    2016-01-01

    Background.  Live vaccines may have nonspecific beneficial effects on morbidity and mortality. This study examines whether children who had the live-attenuated oral polio vaccine (OPV) as the most recent vaccine had a different rate of admissions for infectious diseases than children with inactivated diphtheria-tetanus-pertussis-polio-Haemophilus influenzae type b vaccine (DTaP-IPV-Hib) or live measles-mumps-rubella vaccine (MMR) as their most recent vaccine. Methods.  A nationwide, register-based, retrospective cohort study of 137 403 Danish children born 1997-1999, who had received 3 doses of DTaP-IPV-Hib, were observed from 24 months (first OPV dose) to 36 months of age. Results.  Oral polio vaccine was associated with a lower rate of admissions with any type of non-polio infection compared with DTaP-IPV-Hib as most recent vaccine (adjusted incidence rate ratio [IRR], 0.85; 95% confidence interval [CI], .77-.95). The association was separately significant for admissions with lower respiratory infections (adjusted IRR, 0.73; 95% CI, .61-.87). The admission rates did not differ for OPV versus MMR. Conclusions.  Like MMR, OPV was associated with fewer admissions for lower respiratory infections than having DTaP-IPV-Hib as the most recent vaccination. Because OPV is now being phased-out globally, further studies of the potential beneficial nonspecific effects of OPV are warranted. PMID:26885538

  15. Does mental health service integration affect compulsory admissions?

    Directory of Open Access Journals (Sweden)

    André I. Wierdsma

    2009-09-01

    Full Text Available Background: Over recent years, the number of compulsory admissions in many countries has increased, probably as a result of the shift from inpatient to outpatient mental health care. This might be mitigated by formal or collaborative relationships between services. Methods: In a retrospective record linkage study, we compared two neighboring districts, varying in level of service integration. Two periods were combined: 1991–1993 and 2001–2003. We included patients aged 18–60, who had a first emergency compulsory admission (n=830. Their psychiatric history was assessed, and service-use after admission was monitored over a 12-month follow-up. Results: Over a 10-year period, compulsory admission rates increased by 47%. Difference in relative increase between the integrated and non-integrated services was 14%. Patient characteristics showed different profiles in the two districts. Length of stay was >10 days shorter in the integrated district, where the proportion of involuntary readmissions decreased more, and where aftercare was swift and provided to about 10% more patients than in the non-integrated district. Conclusions: Services outcomes showed better results where mental healthcare was more integrated. However, limited effects were found and other factors than integration of services may be more important in preventing compulsory admissions.

  16. Potential Utility of Non-Cognitive Constructs in Graduate Admissions

    Science.gov (United States)

    Miller, Casey

    2015-03-01

    It is becoming clear that the methods employed by many graduate admissions committees need updating. Regarding outcomes, we cannot select students that will actually graduate much better than would a coin toss. Further, the GRE is often misused. For example, the most recent GRE general test data (2006-2007) shows that for US citizens in the physical sciences, a cut-off score of ~64th percentile (700/155 on old/new test) would eliminate from eligibility: 63% of women vs 42% of men; 76% of all under-represented minorities vs 38% of Asian and 47% of White applicants. Fortunately, Organizational Psychologists have identified and validated several ``non-cognitive constructs'' for admissions: aspects of personality (conscientiousness); and self-management factors. Some intriguing facts about these parameters: they are measurable with the help of social scientists; they do not show race/ethnicity/gender performance differences; they are orthogonal to cognitive metrics measured by GPA and tests scores. These are proven to enhance both validity and diversity in admissions. My goals for this talk are to overview the non-cognitive constructs with the most potential for being used in physics graduate admissions, and to suggest example admissions protocols.

    While knowledge on service users' perspective on their admissions to psychiatric wards has improved substantially in the last decade, there is a paucity of knowledge of the perspectives of caregivers. This study aimed to determine caregiver's perception of the levels of perceived coercion, perceived pressures and procedural justice experienced by service users during their admission to acute psychiatric in-patient units. The perspective of caregivers were then compared to the perspectives of their related service users, who had been admitted to five psychiatric units in Ireland. Caregivers were interviewed using an adapted version of the MacArthur admission experience interview. Sixty-six caregivers participated in this study and the majority were parents. Seventy one percent of service users were admitted involuntarily and nearly half had a diagnosis of schizophrenia or schizoaffective disorder. Caregivers of involuntarily admitted individuals perceived the service users' admission as less coercive than reported by the service users. Caregivers also perceived a higher level of procedural justice in comparison to the level reported by service users. Reducing the disparity of perceptions between caregivers and service users could result in caregivers having a greater understanding of the admission process and why some service users may be reluctant to be admitted.

    Full Text Available Context In a prior report involving patients with hemoconcentration at admission, those with necrotizing pancreatitis presented significantly earlier than those with interstitial disease suggesting that duration of abdominal pain prior to presentation may have prognostic significance in acute pancreatitis. Objectives The aim of the present study was to determine whether the duration of abdominal pain prior to admission influences the severity of acute pancreatitis. Methods During a five-year period, all patients presenting directly to our hospital with their first episode of acute pancreatitis were enrolled in a cohort study. We analyzed data obtained from records of all such patients and performed a separate analysis on those with hemoconcentration (hematocrit equal to, or greater than, 44% at presentation to determine whether duration of abdominal pain prior to presentation was associated with severity of acute pancreatitis. Duration of abdominal pain wascategorized as persisting for either less than 12 h or 12 h or more prior to arrival. Prognostic markers of severity included admission hematocrit and blood urea nitrogen (BUN, as well as the development of systemic inflammatory response syndrome (SIRS during the initial 24 h of hospitalization. Outcome measures included pancreatic necrosis based on contrast-enhanced CT scanning, need for intensive care, length of hospitalization, and death. Radiologic severity of peripancreatic inflammatory changes was assessed within 48 h of admission in accordance with the Balthazar-Ranson scoring system (A-E. Results Among a total of 318 patients, there were 62 (19.5% with hemoconcentration at admission. Among the 318 patients, there was no significant difference in the prevalence of pancreatic necrosis when comparing the less than 12 h group to the 12 h or more group. Among the 62 patients with hemoconcentration, those admitted within 12 h compared to those admitted 12 h or more following the onset of

    Full Text Available Background: Projected increases in weather variability due to climate change will have severe consequences on human health, increasing mortality, and disease rates. Among these, cardiovascular diseases (CVD, highly prevalent among the elderly, have been shown to be sensitive to extreme temperatures and heat waves. Objectives: This study aimed to find out the relationship between daily temperature (and other weather parameters and daily CVD hospital admissions among the elderly population in Thai Nguyen province, a northern province of Vietnam. Methods: Retrospective data of CVD cases were obtained from a data base of four hospitals in Thai Nguyen province for a period of 5 years from 2008 to 2012. CVD hospital admissions were aggregated by day and merged with daily weather data from this period. Distributed lag non-linear model (DLNM was used to derive specific estimates of the effect of weather parameters on CVD hospital admissions of up to 30 days, adjusted for time trends using b-splines, day of the week, and public holidays. Results: This study shows that the average point of minimum CVD admissions was at 26°C. Above and below this threshold, the cumulative CVD admission risk over 30 lag days tended to increase with both lower and higher temperatures. The cold effect was found to occur 4–15 days following exposure, peaking at a week's delay. The cumulative effect of cold exposure on CVD admissions was statistically significant with a relative risk of 1.12 (95% confidence interval: 1.01–1.25 for 1°C decrease below the threshold. The cumulative effect of hot temperature on CVD admissions was found to be non-significant and was estimated to be at a relative risk of 1.17 (95% confidence interval: 0.90–1.52 for 1°C increase in the temperature. No significant association was found between CVD admissions and the other weather variables. Conclusion: Exposure to cold temperature is associated with increasing CVD admission risk among the

    In this paper, we research an admission control scheme of integrated voice and data CDMA/TDD (Code division multiple access/Time division duplex) system considering asymmetric traffic and power limit. A new user can access the system only if the outage probabilities it experiences on the uplink and downlink time slots are below a threshold value. Based on the power limit the results show the voice and data blocking probabilities under different cell coverage~ arrival rates and various uplink/downlink time slot allocation patterns. Furthermore, multicode and multislot schemes are also evaluated under the presented admission control scheme.

  4. Asymptotic admissibility of priors and elliptic differential equations

    CERN Document Server

    Hartigan, J A

    2010-01-01

    We evaluate priors by the second order asymptotic behavior of the corresponding estimators.Under certain regularity conditions, the risk differences between efficient estimators of parameters taking values in a domain D, an open connected subset of R^d, are asymptotically expressed as elliptic differential forms depending on the asymptotic covariance matrix V. Each efficient estimator has the same asymptotic risk as a 'local Bayes' estimate corresponding to a prior density p. The asymptotic decision theory of the estimators identifies the smooth prior densities as admissible or inadmissible, according to the existence of solutions to certain elliptic differential equations. The prior p is admissible if the quantity pV is sufficiently small near the boundary of D. We exhibit the unique admissible invariant prior for V=I,D=R^d-{0). A detailed example is given for a normal mixture model.

    Full Text Available UNLABELLED: Although increasing numbers of very elderly patients are requiring intensive care, few large sample studies have investigated ICU admission of very elderly patients. Data on pre triage by physicians from other specialities is limited. This observational cohort study aims at examining inter-hospital variability of ICU admission rates and its association with patients' outcomes. All patients over 80 years possibly qualifying for ICU admission who presented to the emergency departments (ED of 15 hospitals in the Paris (France area during a one-year period were prospectively included in the study. Main outcome measures were ICU eligibility, as assessed by the ED and ICU physicians; in-hospital mortality; and vital and functional status 6 months after the ED visit. 2646 patients (median age 86; interquartile range 83-91 were included in the study. 94% of participants completed follow-up (n = 2495. 12.4% (n = 329 of participants were deemed eligible for ICU admission by ED physicians and intensivists. The overall in-hospital and 6-month mortality rates were respectively 27.2% (n = 717 and 50.7% (n = 1264. At six months, 57.5% (n = 1433 of patients had died or had a functional deterioration. Rates of patients deemed eligible for ICU admission ranged from 5.6% to 38.8% across the participating centers, and this variability persisted after adjustment for patients' characteristics. Despite this variability, we found no association between level of ICU eligibility and either in-hospital death or six-month death or functional deterioration. In France, the likelihood that a very elderly person will be admitted to an ICU varies widely from one hospital to another. Influence of intensive care admission on patients' outcome remains unclear.

    Full Text Available We explore the challenges faced by counseling psychologist when working at the Children's Helpline in cases of prank calls. The category of prank calls include such calls, when the caller asks the psychologist to discuss the imaginary situation, or do not formulate a query at all. On the basis of empirical data, we revealed the main varieties of such calls: call jokes, fantasy calls, intrusive calls, insulting calls, prank calls, calls of a sexual nature, dating calls. We explore the possible motivations of children and adolescents, entertaining by phone calls: experimentation with new social roles, expression of negative emotions, cognitive motivation, etc. We show the principles and strategies of counselors of Children's helpline working with this type of calls: they are based on cultural-historical psychology ideas and V.

    Open-source software (OSS) encourages computer programmers to reuse software components written by others. In evolutionary bioinformatics, OSS comes in a broad range of programming languages, including C/C++, Perl, Python, Ruby, Java, and R. To avoid writing the same functionality multiple times for different languages, it is possible to share components by bridging computer languages and Bio* projects, such as BioPerl, Biopython, BioRuby, BioJava, and R/Bioconductor. In this chapter, we compare the two principal approaches for sharing software between different programming languages: either by remote procedure call (RPC) or by sharing a local call stack. RPC provides a language-independent protocol over a network interface; examples are RSOAP and Rserve. The local call stack provides a between-language mapping not over the network interface, but directly in computer memory; examples are R bindings, RPy, and languages sharing the Java Virtual Machine stack. This functionality provides strategies for sharing of software between Bio* projects, which can be exploited more often. Here, we present cross-language examples for sequence translation, and measure throughput of the different options. We compare calling into R through native R, RSOAP, Rserve, and RPy interfaces, with the performance of native BioPerl, Biopython, BioJava, and BioRuby implementations, and with call stack bindings to BioJava and the European Molecular Biology Open Software Suite. In general, call stack approaches outperform native Bio* implementations and these, in turn, outperform RPC-based approaches. To test and compare strategies, we provide a downloadable BioNode image with all examples, tools, and libraries included. The BioNode image can be run on VirtualBox-supported operating systems, including Windows, OSX, and Linux.

  12. Lie-admissible structure of Hamilton's original equations with external terms

    International Nuclear Information System (INIS)

    As a necessary additional step in preparation of our operator studies of closed nonhamiltonian systems, in this note we consider the algebraic structure of the original equations proposed by Lagrange and Hamilton, those with external terms representing precisely the contact nonpotential forces of the interior dynamical problem. We show that the brackets of the theory violate the conditions to characterize any algebra. Nevertheless, when properly written, they characterize a covering of the Lie-isotopic algebras called Lie-admissible algebras. It is indicated that a similar occurrence exists for conventional operator treatments, e.g. for nonconservative nuclear cases characterized by nonhermitean Hamiltonians. This occurrence then prevents a rigorous treatment of basic notions, such as that of angular momentum and spin spin, which are centrally dependent on the existence of a consistent algebraic structure. The emergence of the Lie-admissible algebras is therefore expected to be unavoidable for any rigorous operator treatment of open systems with nonlinear, nonlocal and nonhamiltonian external forces.

  15. On the Bayesness, minimaxity and admissibility of point estimators of allelic frequencies.

    Martínez, Carlos Alberto; Khare, Kshitij; Elzo, Mauricio A

    2015-10-21

    In this paper, decision theory was used to derive Bayes and minimax decision rules to estimate allelic frequencies and to explore their admissibility. Decision rules with uniformly smallest risk usually do not exist and one approach to solve this problem is to use the Bayes principle and the minimax principle to find decision rules satisfying some general optimality criterion based on their risk functions. Two cases were considered, the simpler case of biallelic loci and the more complex case of multiallelic loci. For each locus, the sampling model was a multinomial distribution and the prior was a Beta (biallelic case) or a Dirichlet (multiallelic case) distribution. Three loss functions were considered: squared error loss (SEL), Kulback-Leibler loss (KLL) and quadratic error loss (QEL). Bayes estimators were derived under these three loss functions and were subsequently used to find minimax estimators using results from decision theory. The Bayes estimators obtained from SEL and KLL turned out to be the same. Under certain conditions, the Bayes estimator derived from QEL led to an admissible minimax estimator (which was also equal to the maximum likelihood estimator). The SEL also allowed finding admissible minimax estimators. Some estimators had uniformly smaller variance than the MLE and under suitable conditions the remaining estimators also satisfied this property. In addition to their statistical properties, the estimators derived here allow variation in allelic frequencies, which is closer to the reality of finite populations exposed to evolutionary forces.

    Background: Clinical major adverse cardiovascular event (MACE) prediction of acute coronary syndrome (ACS) is important for a number of applications including physician decision support, quality of care assessment, and efficient healthcare service delivery on ACS patients. Admission records, as typical media to contain clinical information of patients at the early stage of their hospitalizations, provide significant potential to be explored for MACE prediction in a proactive manner. Methods: We propose a hybrid approach for MACE prediction by utilizing a large volume of admission records. Firstly, both a rule-based medical language processing method and a machine learning method (i.e., Conditional Random Fields (CRFs)) are developed to extract essential patient features from unstructured admission records. After that, state-of-the-art supervised machine learning algorithms are applied to construct MACE prediction models from data. Results: We comparatively evaluate the performance of the proposed approach on a real clinical dataset consisting of 2930 ACS patient samples collected from a Chinese hospital. Our best model achieved 72% AUC in MACE prediction. In comparison of the performance between our models and two well-known ACS risk score tools, i.e., GRACE and TIMI, our learned models obtain better performances with a significant margin. Conclusions: Experimental results reveal that our approach can obtain competitive performance in MACE prediction. The comparison of classifiers indicates the proposed approach has a competitive generality with datasets extracted by different feature extraction methods. Furthermore, our MACE prediction model obtained a significant improvement by comparison with both GRACE and TIMI. It indicates that using admission records can effectively provide MACE prediction service for ACS patients at the early stage of their hospitalizations. PMID:27649220

    2016-01-01

    Previous research has suggested that judgment calls (i.e., methodological choices made in the process of conducting a meta-analysis) have a strong influence on meta-analytic findings and question their robustness. However, prior research applies case study comparison or reanalysis of a few meta-analyses with a focus on a few selected judgment calls. These studies neglect the fact that different judgment calls are related to each other and simultaneously influence the outcomes of a meta-analysis, and that meta-analytic findings can vary due to non-judgment call differences between meta-analyses (e.g., variations of effects over time). The current study analyzes the influence of 13 judgment calls in 176 meta-analyses in marketing research by applying a multivariate, multilevel meta-meta-analysis. The analysis considers simultaneous influences from different judgment calls on meta-analytic effect sizes and controls for alternative explanations based on non-judgment call differences between meta-analyses. The findings suggest that judgment calls have only a minor influence on meta-analytic findings, whereas non-judgment call differences between meta-analyses are more likely to explain differences in meta-analytic findings. The findings support the robustness of meta-analytic results and conclusions. PMID:27055205

    通过向客户提示可能需要等待的排队时间来改善顾客满意度是目前呼叫中心的重要手段之一。实践表明,提示时间长短的确定对顾客满意度和呼叫中心效用具有重要影响作用。基于排队论建立了考虑顾客心理行为影响的最大系统效用优化模型,并给出了基于混沌搜索的求解算法。针对一类带有排队等待时间提示的 M/M/N+M 排队模型,研究了排队时间提示对顾客耐心心理与放弃行为的影响规律,用概率函数描述了顾客心理变化和放弃行为,推导了稳态下的排队系统的性能计算公式,构建了最大化系统效用值的优化模型和混沌搜索求解算法。数值实验验证了算法的收敛性和有效性,并给出了不同耐心顾客群体和呼叫中心运营模式下的系统最优提示时间策略和效用值的变化规律,作为实际工作中的指导准则。%One of the important management approaches of call centers is to provide delay time information for the callers in order to improve their satisfactory.The practice indicated that the duration of delay time has the key impact on the customer’s satisfactory and the effectiveness of call centers. According to M/M/N+M queue model with delay information,the influence of delay information on the customer’s patience and balking and reneging behavior is addressed,and the customer’s mental and behavior variation is described by probability functions.Then,the performance calculation formula of queue system is deduced under the stable state.The maximum system utility optimization model with consideration of the customer’s behavior based on queue theory is established,and the chaotic search algorithm is developed.The numerical results verify the effectiveness and convergence of the algorithm. Under various operation models,rules for practice are derived from analysis of the relationship between customer’s patience and call center

    The present study aimed to determine the relationship between the level of air pollutants and the rate of ischemic stroke (IS) admissions to hospitals. In this retrospective cross-sectional study, stroke admissions (January-March 2012 and 2013) to an emergency department and air pollution and meteorological data were gathered. The relationship between air pollutant levels and hospital admission rates were evaluated using the generalize additive model. In all 379 patients with IS were referred to the hospital (52.5% male; mean age 68.2±13.3 years). Both transient (p<0.001) and long-term (p<0.001) rises in CO level increases the risk of IS. Increased weekly (p<0.001) and monthly (p<0.001) average O3 levels amplifies this risk, while a transient increase in NO2 (p<0.001) and SO2 (p<0.001) levels has the same effect. Long-term changes in PM10 (p<0.001) and PM2.5 (p<0.001) also increase the risk of IS. The findings showed that the level of air pollutants directly correlates with the number of stroke admissions to the emergency department. PMID:26866000

    Full Text Available Background: Guillain-Barre syndrome (GBS is an acute immune-mediated peripheral neuropathy usually after an incident. This study was performed to investigate the basic epidemiologic features of GBS in south of Iran.Methods: We studied consecutive patients with GBS in Namazi Hospital of Shiraz, southern Iran. Demographic characteristics of the subjects, i.e. age, sex, and length of hospital stay were extracted. Information regarding yearly admissions for the entire hospital was also gathered. The prevalence of GBS per 10,000 hospital admissions was calculated and stratified by sex and year. Yearly prevalence was compared using the odds ratio (OR and 95% confidence intervals (CI.Results: From January 2000 to December 2009, 389 (232 males and 157 females patients with GBS were admitted in our center. The mean age of patients was 29.8 ± 23.0 years and their mean length of hospital stay was 12.9 ± 11.6 days. The overall mortality rate was 6%. The ratio of admissions due to GBS to the total admissions was significantly higher in 2009, the year of an influenza A (H1N1 virus pandemic.Conclusion: There appears to be an increase in the incidence of GBS in Shiraz. This is in parallel with the increasing trend of some other autoimmune diseases.

  12. A Content Analysis of Medical School Admissions Interviews

    Directory of Open Access Journals (Sweden)

    2003-04-01

    Full Text Available Introduction. Prospective medical school applicants use Internet websites to gain information about medical school interviews as well as to offer their experience in such interviews. This study examined applicants’ reported experiences of interviews and compared them to the purposes of the interview as purported by medical schools. Method. Content analysis of student feedback regarding medical school interviews at 161 medical schools was conducted for entries of over 4600 students applying to medical school who anonymously and voluntarily completed an online questionnaire. Results. Across all medical schools, nearly one half of all cited interview questions addressed non-cognitive characteristics of the applicants. Top ranked medical schools were reported to ask significantly more interpersonal and illegal questions and fewer academic/general knowledge questions than other medical schools. Lower ranked schools did not differ significantly in the types of questions reportedly asked applicants compared to other medical schools. Discussion. Medical school interviews are generally gathering types of information about applicants that admissions personnel identify as important in the admission decision. In addition to measuring interpersonal characteristics, medical school admissions interviews are assessing cognitive abilities and ethical decision-making. Sources on the Internet provide actual medical school interview questions to prospective students. This practice can help them gain an undue advantage in interviewing. Admissions committees and faculty who interview students may want to consider how best to obtain accurate and valid responses from applicants.

    In this study, the objective was to describe and analyse reasons for obstetric admissions to the ICU, severity of illness, level and types of interventions, adverse events and patient outcomes. In a retrospective database study, we identified 291 obstetric patients during pregnancy and puerperium from four Finnish university hospitals. Most were admitted in the post-partum period and hypertensive disorders were the main indications for admissions, followed by obstetric haemorrhage. The median length of stay was 21hours. The most common intervention was blood transfusion and mechanical ventilation was required in nearly one fifth of the patients. Three patients had a prolonged stay and nine had re-admissions. One maternal death was recorded. This study found that severity of illness and organ failure scores describe the obstetric patient as having a good probability of recovery and a short length of stay. However, the obstetric patients reason for admission and their type of delivery were associated with both the severity of illness scores and level of intervention required. Those admitted for non-obstetric reasons and having had a vaginal delivery demonstrated higher severity of illness scores, organ failure scores, and levels of intervention when compared to those admitted for obstetric reasons or those who had delivered by caesarean section. In conclusion, care of these patients can be improved by understanding the severity of illness scores, common ICU interventions and patient outcomes. PMID:27209560

    2016-01-01

    Background: Diabetes ketoacidosis (DKA) is a life-threatening complication of type 1 diabetes mellitus (T1DM). Reducing DKA admissions in children with T1DM requires a coordinated, comprehensive management plan. We aimed to decrease DKA admissions, 30-day readmissions, and length of stay (LOS) for DKA admissions. Methods: A multipronged intervention was designed in 2011 to reach all patients: (1) increase insulin pump use and basal-bolus regimen versus sliding scales, (2) transform educational program, (3) increased access to medical providers, and (4) support for patients and families. A before-after study was conducted comparing performance outcomes in years 2007-2010 (preintervention) to 2012-2014 (postintervention) using administrative data and Wilcoxon rank sum and Fischer exact tests. Results: DKA admissions decreased by 44% postintervention (16.7 vs 9.3 per 100 followed patient-years; P = .006), unique patient 30-day readmissions decreased from 20% to 5% postintervention (P = .001), and median LOS significantly decreased postintervention (P < .0001). Although not an original goal of the study, median hemoglobin A1C of a subset of the population transitioned from sliding scale decreased, 10.3% to 8.9% (P < .02). Conclusions: When clinical and widespread program interventions were used, significant reductions in DKA hospitalizations, 30-day readmissions, and LOS occurred for pediatric T1DM. Continuous performance improvement efforts are needed for improving DKA outcomes. PMID:27749721

    Purpose Hospitals have used process redesign to increase the efficiency of the emergency department (ED) to cope with increasing demand. While there are published studies suggesting a positive outcome, recent reviews have reported that it is difficult to conclude that these approaches are effective as a result of substandard research methodology. The purpose of this paper is to explore the perceptions of hospital staff on the impact of a process redesign initiative on quality of care. Design/methodology/approach A retrospective qualitative case study examining a Lean Six Sigma (LSS) initiative in a large metropolitan hospital from 2009 to 2010. Non-probability sampling identified interview subjects who, through their participation in the redesign initiative, had a detailed understanding of the implementation and outcomes of the initiative. Between April 2012 and January 2013 26 in-depth semi-structured interviews were conducted and analysed with thematic content analysis. Findings There were four important findings. First, when asked to comment on the impact of the LSS implementation, without prompting the staff spoke of quality of care. Second, there was little agreement among the participants as to whether the project had been successful. Third, despite the recognition of the need for a coordinated effort across the hospital to improve ED access, the redesign process was not successful in reducing existing divides among clinicians and among managers and clinicians. Finally, staff expressed tension between production processes to move patients more quickly and their duty of care to their patients as individuals. Originality/value One of the first studies to explore the impact of process redesign through in-depth interviews with participating staff, this study adds further evidence that organisations implementing process redesign must ensure the supporting management practices are in place.

  20. Specialty-specific admission: a cost-effective intervention?

    LENUS (Irish Health Repository)

    Slattery, E

    2012-02-01

    INTRODUCTION: Cost effectiveness of healthcare has become an important component in its delivery. Current practices need to be assessed and measured for variations that may lead to financial savings. Speciality specific admission is known not only to lead improved clinical outcomes but also to lead important cost reductions. METHODS: All patients admitted to an Irish teaching hospital via the emergency department over a 2-year period with a gastroenterology (GI) related illness were included in this analysis.GI illness was classified using the Disease related grouping (DRG) system. Mean length of stay (LOS) and patient level costing (PLC) were calculated. Differences between DRGs with respect to speciality (i.e. specialist vs. non-specialist) were calculated for the five commonest DRGs. RESULTS: Significant variations in LOS and PLC were demonstrated in the DRGs. Mean LOS varied with increasing complexity, from 3.2 days for non-complex GI haemorrhage to 14.4 days for complex alcohol related cirrhosis as expected. A substantial difference in LOS within DRG groups was demonstrated by large standard deviations in the mean (up to 8.1 days in some groups) and was independent of complexity of cases. PLC also varied widely in both complex and non-complex cases with standard deviations of up to 17,342 noted. Specialty-specific admission was associated with shorter LOS for most GI admissions. CONCLUSION: Significant disparity exists for both LOS and PLC for most GI diagnoses. Specialty-specific admissions are associated with reduced LOS. Specialty-specific admission would appear to be cost-effective which may also lead to improved clinical outcomes.

    Previous studies examining daily temperature and stroke incidence have given conflicting results. We undertook this retrospective study of all stroke admissions in those aged 35 years old and above to Hong Kong public hospitals from 1999 through 2006 in order to better understand the effects of meteorological conditions on stroke risk in a subtropical setting. We used Poisson Generalized Additive Models with daily hemorrhagic (HS) and ischemic stroke (IS) counts separately as outcomes, and daily mean temperature, humidity, solar radiation, rainfall, air pressure, pollutants, flu consultation rates, day of week, holidays, time trend and seasonality as predictors. Lagged effects of temperature, humidity and pollutants were also considered. A total of 23,457 HS and 107,505 IS admissions were analyzed. Mean daily temperature had a strong, consistent, negative linear association with HS admissions over the range (8.2-31.8°C) observed. A 1°C lower average temperature over the same day and previous 4 days (lags 0-4) being associated with a 2.7% (95% CI: 2.0-3.4%, P < .0.0001) higher admission rate after controlling for other variables. This association was stronger among older subjects and females. Higher lag 0-4 average change in air pressure from previous day was modestly associated with higher HS risk. The association between IS and temperature was weaker and apparent only below 22°C, with a 1°C lower average temperature (lags 0-13) below this threshold being associated with a 1.6% (95% CI:1.0-2.2%, P < 0.0001) higher IS admission rate. Pollutant levels were not associated with HS or IS. Future studies should examine HS and IS risk separately.

    Some studies of patients with acute myocardial infarction have reported that hyperglycaemia at admission may be associated with a worse outcome. This study sought to evaluate the association of blood glucose at admission with the outcome of unselected patients with acute coronary syndrome (ACS). Using the Acute Myocardial Infarction and unstable angina in Switzerland (AMIS Plus) registry, ACS patients were stratified according to their blood glucose on admission: group 1: 2.80-6.99 mmol/L, group 2: 7.00-11.09 mmol/L and group 3: > 11.10 mmol/L. Odds ratios for in-hospital mortality were calculated using logistic regression models. Of 2,786 patients, 73% were male and 21% were known to have diabetes. In-hospital mortality increased from 3% in group 1 to 7% in group 2 and to 15% in group 3. Higher glucose levels were associated with larger enzymatic infarct sizes (p<0.001) and had a weak negative correlation with angiographic or echographic left ventricular ejection fraction. High admission glycaemia in ACS patients remains a significant independent predictor of in-hospital mortality (adjusted OR 1.08; 95% confidence intervals [CI] 1.05-1.14, p<0.001) per mmol/L. The OR for in-hospital mortality was 1.04 (95% CI 0.99-1.1; p=0.140) per mmol/L for patients with diabetes but 1.21 (95% CI 112-1.30; p<0.001) per mmol/L for non-diabetic patients. In conclusion, elevated glucose level in ACS patients on admission is a significant independent predictor of in-hospital mortality and is even more important for patients who do not have known diabetes.

    Full Text Available Abstract Background Although not recommended in treatment guidelines, previous studies have shown a frequent use of more than one antipsychotic agent among patients with schizophrenia. The main aims of the present study were to explore the antipsychotic treatment regimen among patients with schizophrenia in a catchment area-based sample and to investigate clinical characteristics associated with antipsychotic combination treatment. Methods The study included 329 patients diagnosed with schizophrenia using antipsychotic medication. Patients were recruited from all psychiatric hospitals in Oslo. Diagnoses were obtained by use of the Structured Clinical Interview for DSM-IV Axis I disorders (SCID-I. Additionally, Global Assessment of Functioning (GAF, Positive and Negative Syndrome Scale (PANSS and number of hospitalisations and pharmacological treatment were assessed. Results Multiple hospital admissions, low GAF scores and high PANSS scores, were significantly associated with the prescription of combination treatment with two or more antipsychotics. The use of combination treatment increased significantly from the second hospital admission. Combination therapy was not significantly associated with age or gender. Regression models confirmed that an increasing number of hospital admission was the strongest predictor of the use of two or more antipsychotics. Conclusions Previous hospital admissions and disease severity measured by high PANSS scores and low GAF scores, predict the use of antipsychotic combination treatment in patients with schizophrenia. Future studies should further explore the use of antipsychotic drug treatment in clinical practice and partly based on such data establish more robust treatment guidelines for patients with persistently high symptom load.

    2016-09-01

    Full Text Available Introduction: Attending physician judgment is the traditional standard of care for emergency department (ED admission decisions. The extent to which variability in admission decisions affect cost and quality is not well understood. We sought to determine the impact of variability in admission decisions on cost and quality. Methods: We performed a retrospective observational study of patients presenting to a university-affiliated, urban ED from October 1, 2007, through September 30, 2008. The main outcome measures were admission rate, fiscal indicators (Medicaid-denied payment days, and quality indicators (15- and 30-day ED returns; delayed hospital admissions. We asked each Attending to estimate their inpatient admission rate and correlated their personal assessment with actual admission rates. Results: Admission rates, even after adjusting for known confounders, were highly variable (15.2%-32.0% and correlated with Medicaid denied-payment day rates (p=0.038. There was no correlation with quality outcome measures (30-day ED return or delayed hospital admission. There was no significant correlation between actual and self-described admission rate; the range of mis-estimation was 0% to 117%. Conclusion: Emergency medicine attending admission rates at this institution are highly variable, unexplained by known confounding variables, and unrelated to quality of care, as measured by 30-day ED return or delayed hospital admission. Admission optimization represents an important untapped potential for cost reduction through avoidable hospitalizations, with no apparent adverse effects on quality.

  17. Bonobos extract meaning from call sequences.

    Directory of Open Access Journals (Sweden)

    Zanna Clay

    Full Text Available Studies on language-trained bonobos have revealed their remarkable abilities in representational and communication tasks. Surprisingly, however, corresponding research into their natural communication has largely been neglected. We address this issue with a first playback study on the natural vocal behaviour of bonobos. Bonobos produce five acoustically distinct call types when finding food, which they regularly mix together into longer call sequences. We found that individual call types were relatively poor indicators of food quality, while context specificity was much greater at the call sequence level. We therefore investigated whether receivers could extract meaning about the quality of food encountered by the caller by integrating across different call sequences. We first trained four captive individuals to find two types of foods, kiwi (preferred and apples (less preferred at two different locations. We then conducted naturalistic playback experiments during which we broadcasted sequences of four calls, originally produced by a familiar individual responding to either kiwi or apples. All sequences contained the same number of calls but varied in the composition of call types. Following playbacks, we found that subjects devoted significantly more search effort to the field indicated by the call sequence. Rather than attending to individual calls, bonobos attended to the entire sequences to make inferences about the food encountered by a caller. These results provide the first empirical evidence that bonobos are able to extract information about external events by attending to vocal sequences of other individuals and highlight the importance of call combinations in their natural communication system.

    2010-01-01

    Full Text Available Problem statement: Mathematically little is known of college admission criteria as in school grade point average, admission test scores or rank in class and weighting of the criteria into a composite equation. Approach: This study presented a method to obtain weights on “composite admission” equation. The method uses an iterative procedure to build a prediction equation for an optimal weighted admission composite score. The three-predictor variables, high school average, entrance exam scores and rank in class, were regressed on college Grade Point Average (GPA. The weights for the composite equation were determined through regression coefficients and numerical approach that correlate the composite score with college GPA. Results: A set of composite equations were determined with the weights on each criteria in a composite equation. Conclusion: This study detailed a substantiated algorithm and based on an optimal composite score, comes out with an original and unique structured composite score equation for admissions, which can be used by admission officers at colleges and universities.

    Although several factors such as cigarette smoking, blood pressure, diabetes, obesity, hypercholesterolemia, physical inactivity and dietary factors have been well documented to increase the risk for stroke, there are conflicting data about the role of meteorological variables in the etiology of stroke. We conducted a retrospective study to investigate the association between weather patterns, including daily temperature, humidity, wind speed, and air pressure, and stroke admissions to the Emergency Department of Atatürk Training and Research Hospital in Ankara, Turkey, between January 2009 and April 2010. Generalized additive models with logistic link function were used to investigate the relationship between predictors and days with and without stroke admission at lags 0-4. A total of 373 stroke patients were admitted to the emergency department (ED) between January 2009 and April 2010. Of patients, 297 had ischemic stroke (IS), 34 hemorrhagic stroke (HS), and 42 subarachnoidal hemorrhage (SAH). Although we did not find any association between overall admissions due to stroke and meteorological parameters, univariable analysis indicated that there were significantly more SAH cases on days with lower daily mean temperatures of 8.79 ± 8.75 °C as compared to relatively mild days with higher temperatures (mean temperature = 11.89 ± 7.94 °C, p = 0.021). The multivariable analysis demonstrated that admissions due to SAH increased on days with lower daily mean temperatures for the same day (lag 0; odds ratio (OR) [95 % confidence interval (95 % CI)] = 0.93 [0.89-0.98], p = 0.004) and lag 1 (OR [95 % CI] =0.76 [0.67-0.86], p = 0.001). Furthermore, the wind speed at both lag 1 (OR [95 % CI] = 1.63 [1.27-2.09], p = 0.001) and lag 3 (OR [95 % CI] = 1.43 [1.12-1.81], p = 0.004) increased admissions due to HS, respectively. In conclusion, our study demonstrated that there was an association between ED admissions due to SAH and HS and weather conditions suggesting that

    In virtualized cloud computing platform, the key security problem is to guarantee trustworthiness of the softwares which are running in the platform. Integrity measurement and verification has been proposed and studied by many researchers as an effective way to verify the integrity of computer systems. However, existing approaches have some limitations on compatibility, security and maintainability, and cannot be applied into the cloud computing platform. In this paper, we propose a approach named VMGuard, which leverages VMM to enable take integrity measurement outside the operating system. We adopt VMM-based system call interception technique to detect the execution of binaries. System call correlation and guest OS file system metadata reconstruction are proposed to verify the integrity of software in guest OS. We have developed a prototype of VMGuard and implemented it in two mainstream virtual machine monitors, Qemu and KVM, respectively. We also evaluate the effectiveness and performance overhead of our approach by comprehensive experiments. The results show that VMGuard achieves effective integrity measurement with less than 10% overhead.%在虚拟化云计算平台中,如何保证其上运行软件的可信性是云平台广泛应用的关键.完整性测量与验证技术是保证软件系统可信性的一种主要方法.然而,现有的软件完整性验证系统大多需要修改操作系统内核,很难为大规模虚拟机环境中的众多异构系统提供一致解决方案,且无法抵御内核级恶意攻击.针对当前方法在兼容性、安全性以及可管理性上存在的问题,设计并实现了一种在VMM层基于系统调用分析技术来验证软件完整性的方法VMGuard.它通过截获客户操作系统中的系统调用来识别软件加载,并基于系统调用关联性分析和虚拟机文件系统元数据重构技术来验证客户操作系统中软件的完整性,在Qemu和KVM两种主流虚拟化平台上实现了VMGuard,

    Full Text Available Background: Call handlers employed in call centers repeatedly undergo stress in their day-to-day lives and this can have deleterious effects on their health. Objectives: The objectives were to study the levels of stress, anxiety, and depression, and their predictors among call handlers employed in international call centers in the National Capital Region (NCR of Delhi. Materials and Methods: A cross-sectional questionnaire-based survey was conducted among 375 call handlers aged 18-39 years. Depression Anxiety Stress Scale- 42 (DASS-42 was used to measure stress, anxiety, and depression along with a pretested sociodemographic questionnaire. Univariate analysis was done to find out the association of stress, anxiety, and depression with various factors. Variables with P < 0.25 were included in multiple logistic regression and three models were developed each for stress, anxiety, and depression. Results: The prevalence of stress, anxiety, and depression among call handlers was 46.7%, 57.1%, and 62.9% respectively. Abnormal sleep quality, prolonged travel time, and lack of relaxation facilities at the office were predictors of stress and depression. The presence of physical ailments, the absence of hobbies, temporary/part-time employment, and traveling long-distance to office were significant predictors of anxiety among call handlers. Conclusion: Call handlers face a high burden of stress, anxiety, and depression. Public health specialists need to pay adequate attention to their health problems.

    Many studies address the effect of weekend admission on patient outcomes. This population-based study aimed to evaluate the relationship between weekend admission and the treatment process and outcomes of general internal medicine patients in Taiwan.A total of 82,340 patients (16,657 weekend and 65,683 weekday admissions) aged ≥20 years and admitted to the internal medicine departments of 17 medical centers between 2007 and 2009 were identified from the Taiwan National Health Insurance Research Database. A generalized estimating equation (GEE) analysis was used to compare patients admitted on weekends and those admitted on weekdays.Patients who were admitted on weekends were more likely to undergo intubation (odds ratio [OR]: 1.27; 95% confidence interval [CI]: 1.16-1.39; P medicine patients who were admitted on weekends experienced more intensive care procedures and higher ICU admission, in-hospital mortality, and treatment cost. Intensive care utilization may serve as early indicator of poorer outcomes and a potential entry point to offer preventive intervention before proceeding to intensive treatment.

    Full Text Available Background and Aim: Medication Errors can result in drug-related problems (DRPs. Insight into the frequency, type, and severity of DRPs could help reduce their incidence. The aim of the present study was to estimate the prevalence of admissions as a result of DRPs at the Emergency Department (ED of a university hospital in the Kingdom of Saudi Arabia. Materials and Methods: Files of suspected cases of DRPs reporting to ED in the year 2012 were scrutinized. Suspicion arose from the hospital record system based on Diagnosis Code Numbers (ICD-9-CM, Professional 2010 and from triggers, such as some drugs, laboratory tests, and signs and symptoms pointing to DRPs. Results: Of 5574 admissions, 253 (4.5% were DRPs and were categorized as: Overdose toxicity and side effects of drugs 50 (19.8%, drug-interactions 29 (11.5%, accidental and suicidal drug ingestions 26 (10.3%, drug abuse 18 (7.1%, drug allergy 10 (4%, super-infections 8 (3.2%, and noncompliance to treatment 112 (44.3%. About 70% of DRPs were preventable; 67 (26.5% required hospital admission for 7-102 days and 10 (4% died. Conclusions: Noncompliance to treatment, overdose toxicity, drug interactions, and drug abuse are important causes of hospital admissions as a result of DRPs. Awareness of prescribers to the problem and their education would help to prevent them and improve patient care.

    Full Text Available In resource-constrained settings and in the context of HIV-infected patients requiring intensive care, value-laden decisions by critical care specialists are often made in the absence of explicit policies and guidelines. These are often based on individual practitioners’ knowledge and experience, which may be subject to bias. We reviewed published information on legislation and practices related to intensive care unit (ICU admission in India, Brazil and South Africa, to assess access to critical care services in the context of HIV. Each of these countries has legal instruments in place to provide their citizens with health services, but they differ in their provision of ICU care for HIV-infected persons. In Brazil, some ICUs have no admission criteria, and this decision vests solely on the ‘availability, and the knowledge and the experience’ of the most experienced ICU specialist at the institution. India has few regulatory mechanisms to ensure ICU care for critically ill patients including HIV-infected persons. SA has made concerted efforts towards non-discriminatory criteria for ICU admissions and, despite the shortage of ICU beds, HIV-infected patients have relatively greater access to this level of care than in other developing countries in Africa, such as Botswana. Policymakers and clinicians should devise explicit policy frameworks to govern ICU admissions in the context of HIV status. S Afr J HIV Med 2013;14(1:15-16. DOI:10.7196/SAJHIVMED.887
