A comparative study of laminoplasty with short segment transpedicular screw fixation versus laminoplasty with anterior fusion in treating extensional cervical spinal cord injury without radio graphic abnormality in adults

Background: Cervical spinal cord injury(CSCI) without major fracture or dislocation is often described as cervical SCI without radiographic abnormality (SCIWORA). Majority of this injury could be without radiographic abnormality but with disrupted anterior longitudinal ligament or intervertebral disc unless examined by MRI. The optimal surgical management of this cervical spinal cord injury remains controversial. This study is to evaluate the clinical advantages of laminoplasty combined with short-segment transpedicular screw fixation for managing this issue. Methods: SCIWORA patients were collected into two groups according to different surgical methods. Patients in group A received laminoplasty combined with transpedicular screw fixation, and patients in group B received anterior cervical fusion combined with laminoplasty. All cervical spine were assessed by X-ray, CT, MRI preoperatively and postoperatively to evaluate the decompression range, bonegraft fusion and instruments location. ASIA grade and JOA score were recorded to assess the neurological function recovery. Complications, surgery time, intraoperative blood loss and hospital stay were compared between two groups. Mean follow-up was at least 2 years. Results: In this study, Forty eight patients were in group A and 54 ones were in group B. All cases were decompressed fully and obtained fusion 6-month postoperatively. The ASIA grade was improved postoperatively, but no significantly different between two groups (p=0.907). The JOA was 6.12±1.76 preoperatively and improved to 11.98±2.98 postoperatively with the 53.13% neurofunction recovery rate in group A, with no significantly different compared with group B(vs 6.63±2.45, p=0.235; vs 12.62±3.59, p=0.303; vs 57.76%, p=0.590)respectively. Total 18 complications occurred but the occurrence was significant lower in group A(p=0.020). The average surgery time was 2.2±0.32 hours, intraoperative blood loss was 304±56ml and hospital stay was 8.2±3.1 days, significantly decreased compared with group B(vs 3.1±0.29, p=0.000; vs 388±61ml, p=0.000; vs 12±2.8days, p=0.000)respectively. Conclusions: Cervical laminoplasty combined with short-segment transpedicular screw fixation is a reliable option to treat SCIWORA patients with CSS. The advantages include achieving sufficient cervical decompression, maintaining cervical stability and avoiding extra anterior cervical fusion which increases surgery time, intraoperative blood loss, postoperative complications and hospital stay.
Benchmarking- Concept and Practice with Particular Reference to the Finance Function

Benchmarking is simply an attempt to learn from the experiences of other organisations with superior performance and initiate improvement programmes. Although a simple concept, benchmarking is not simple to implement. It requires careful planning, allocation of resources and creation of conditions conducive to the implementation of the lessons learnt to make it an effective management tool. The report will help practitioners with no experience of benchmarking to develop a clear understanding of the concept. It will also provide them with an overview of practical aspects of benchmarking and examples of its successful application.

COMPARACIÓN DE MODELOS DE CLASIFICACIÓN AUTOMÁTICA DE PATRONES TEXTURALES DE MINERALES PRESENTES EN LOS CARBONES COLOMBIANOS

The automatic classification of objects is a very interesting approach under several problem domains. This paper outlines some results obtained under different classification models to categorize textural patterns of minerals using real digital images. The data set used was characterized by a small size and noise presence. The implemented models were the Bayesian classifier, Neural Network (2-5-1), Support Vector Machine, decision tree and 3-nearest neighbours. The results after applying crossed validation show that the Bayesian model (84%) proved better predictive capacity than the others, mainly due to its noise robustness behaviour. The Neuronal Network (68%) and the SVM (67%) gave promising results, because they could be improved increasing the data amount used, while the decision tree (55%) and k-NN (54%) did not seem to be adequate for this problem, because of their sensibility to noise.

DEVELOPMENT AND DEPLOYMENT OF THE MOBILE ARM RETRIEVAL SYSTEM (MARS) - 12187

Washington River Protection Solutions (WRPS) is developing and deploying Mobile Arm Retrieval System (MARS) technologies solutions to support retrieval of radioactive and chemical waste from underground single shell storage tanks (SST) located at the Hanford Site, which is near Richland, Washington. WRPS has developed the MARS using a standardized platform that is capable of deploying multiple retrieval technologies. To date, WRPS, working with their mentor-protege company, Columbia Energy and Environmental Services (CEES), has developed two retrieval mechanisms, MARS-Sluicing (MARS-S) and MARS-Vacuum (MARS-V). MARS-S uses pressurized fluids routed through spray nozzles to mobilize waste materials to a centrally located slurry pump (deployed in 2011). MARS-V uses pressurized fluids routed through an eductor nozzle. The eductor nozzle allows a vacuum to be drawn on the waste materials. The vacuum allows the waste materials to be moved to an in-tank vessel, then extracted from the SST and subsequently pumped to newer and safer double shell tanks (DST) for storage until the waste is treated for disposal. The MARS-S system is targeted for sound SSTs (i.e., non leaking tanks). The MARS-V is targeted for assumed leaking tanks or those tanks that are of questionable integrity. Both versions of MARS are being/have been developed inmore » compliance with WRPS's TFC-PLN-90, Technology Development Management Plan [1]. TFC-PLN-90 includes a phased approach to design, testing, and ultimate deployment of new technologies. The MARS-V is scheduled to be deployed in tank 241-C-105 in late 2012. (authors)« less

An Automatic Personalized Monitoring Service To Provide Security And Privacy Using Cam

Physiological data could then be sent to a central server which could then run a range of web medical applications on these data to return timely advice to the client. Cloud-assisted mHealth monitoring could present a great prospect to perk up the quality of healthcare services and potentially reduce healthcare costs there is a hesitant block in making this technology a reality. It is based on a new alternative of key private proxy re-encryption scheme in which the company only wants to achieve encryption once at the setup phase while shifting the rest computational tasks to the cloud without compromising privacy moreover reducing the computational and communication burden on clients and the cloud. In a remote mHealth monitoring system a client could arrange portable sensors in wireless body sensor networks to collect various physiological data such as blood pressure (BP), breathing rate (BR), Electrocardiogram (ECG/EKG), peripheral oxygen saturation (SpO2) and blood glucose.
Modeling photonic links in Verilog-A

Integrated photonic links are a promising emerging technology that can relieve the interconnect bottleneck in core-to-core and core-to-memory communications of modern processors. Developing and optimizing photonic link systems requires simulation of integrated photonic devices side-by-side with electronic devices at the device, circuit, and system level. In previous efforts to simulate photonic links, the optical and the electrical signals were treated in separate simulators, which resulted in some loss of accuracy. In this thesis, a library of photonic device models is developed in Verilog-A for use in seamless simulation of opto-electronic circuits in Cadence.
Adaptive Control Techniques for Large Space Structures.

Abstract : The Large Space Structure (LSS) research program was originally formulated in response to increasing concern that performance robustness of Air Force LSS systems would be inadequate to meet mission objectives. Uncertainties in both system dynamics and disturbance spectra characterizations (both time varying and stochastic uncertainty) significantly limit the performance attainable with fixed gain, fixed architecture controls. Therefore, use of an adaptive system, where disturbances and/or plant models are identified prior to or during control, gives systems designers more options for minimizing the risk in achieving performance objectives. The aim of adaptive control is to implement in real time and on line as many as possible of the design functions now performed off line by the control engineer to give the controller 'intelligence. ' To realize this aim, both a theory of stability and performance of such inherently nonlinear controls is essential as well as a technology capable of achieving the implementation. The present research concentrated on: (1) on line robust design from identified models - what is referred to here as adaptive calibration; and (2) an analysis of slow-adaptation for adaptive control for LSS. Appendices include articles on the following topics: Methods of averaging for adaptive systems, Transient analysis of adaptive control, Fixed-point theorems for stability analysis of adaptive systems, and Stability theory for adaptive systems.
Investor Sentiment and Stock Price Crash Risk: Evidence from China

ABSTRACT We study the cross-sectional effects of investor sentiment on stock price crash risk from the perspective of investor behavioural biases. We develop a firm-specific investor sentiment measure, and find that stocks with stronger investor sentiment are more prone to a future price crash. The positive relation is more pronounced for stocks eligible for margin trading, as higher investor sentiment induces greater margin buy/cover by optimistic investors. Short interest moderates the impact of optimistic sentiment on crash risk. The positive relation is also particularly prominent for stocks with a more speculative appeal, especially for those with lower institutional ownership.
5582 - THREE-DIMENSIONAL CRACK GROWTH SIMULATION:COMPUTATIONAL ASPECTS AND ANALYSIS OF CRACK TUNNELING TO QUANTIFY COD AS A FUNCTION OF CONSTRAINT

An important task in mixed-mode fracture analysis and prediction is the simulation of crack growth under mixed-mode conditions. To complete such a task, one must have (a) a computer code capable of handling both the kinematics of general crack growth and also the determination of the stress and deformation states during crack growth, and (b) a fracture criterion that can properly predict the instant and direction of crack growth. A current challenge is the simulation of mixed-mode crack growth under three-dimensional (3D) conditions, such as the growth of surface cracks, corner cracks, embedded cracks, and cracks with a curved crack surface and/or a curved crack front. In this work, we will present a brief summary of recent work directed towards computational aspects of a simulation procedure and associated algorithms for simulating arbitrary 3D crack growth under general loading conditions that have been developed and successfully implemented by the authors in a custom, finite element based, crack growth analysis and simulation code CRACK3D. In particular, this paper will present strategies for automatic re-meshing of regions around growing crack fronts in a 3D body, and will discuss verification examples. Then, an application of the simulation code to the detailed analysis of crack tunneling and slanting along measured crack surfaces will be presented [1]. Results of this investigation suggest that the critical COD [2,3] value has a clear dependence on the crack front stress constraint, Am = σm /σe, where σm is the mean stress and σe is the von Mises effective stress. This dependence seems to be linear within the range of computed stress constraint values, with the critical COD decreasing with increasing constraint.

Management competencies anno 2025: consequences for higher education

– The purpose of this paper is to present the results of a business-university collaborative research project that looked to define lower management competencies in the year 2025, specifically for complex, knowledge-intensive organizations. , – The research was done together with a large local airport. Data were gathered by a team of five researchers using focus groups and interviews with 47 employees from 15 different business units. Data were analyzed using thematic and summative content analysis. , – The author found that in order for employees to be effective in a learning organization, they will need to be able to switch between roles. Roles are a combination of fundamental and functional competencies. The former are relational in nature and needed to function throughout the broader organization. The latter are knowledge-related and needed to perform-specific functions. , – Limitations are linked to the generalizability of the results and the fact that the research was organization centric, meaning broad societal changes that might affect individuals’ attitudes and in turn their attitude toward work were not considered. This research does, however, raise some important issues about working effectively in complex organizations and the role higher education has in preparing students. , – Curricula designers in higher education can use the findings to help adapt their current approach to teaching and learning. , – Most work on defining competencies for curricula development fails to delineate between fundamental and functional competencies. There is also little empirical work on how roles can be developed.
Traffic re-engineering : extending resource pooling through the application of re-feedback

Parallelism pervades the Internet, yet efficiently pooling this increasing path diversity has remained elusive. With no holistic solution for resource pooling, each layer of the Internet architecture attempts to balance traffic according to its own needs, potentially at the expense of others. From the edges, traffic is implicitly pooled over multiple paths by retrieving content from different sources. Within the network, traffic is explicitly balanced across multiple links through the use of traffic engineering. This work explores how the current architecture can be realigned to facilitate resource pooling at both network and transport layers, where tension between stakeholders is strongest. The central theme of this thesis is that traffic engineering can be performed more efficiently, flexibly and robustly through the use of re-feedback. A cross-layer architecture is proposed for sharing the responsibility for resource pooling across both hosts and network. Building on this framework, two novel forms of traffic management are evaluated. Efficient pooling of traffic across paths is achieved through the development of an in-network congestion balancer, which can function in the absence of multipath transport. Network and transport mechanisms are then designed and implemented to facilitate path fail-over, greatly improving resilience without requiring receiver side cooperation. These contributions are framed by a longitudinal measurement study which provides evidence for many of the design choices taken. A methodology for scalably recovering flow metrics from passive traces is developed which in turn is systematically applied to over five years of interdomain traffic data. The resulting findings challenge traditional assumptions on the preponderance of congestion control on resource sharing, with over half of all traffic being constrained by limits other than network capacity. All of the above represent concerted attempts to rethink and reassert traffic engineering in an Internet where competing solutions for resource pooling proliferate. By delegating responsibilities currently overloading the routing architecture towards hosts and re-engineering traffic management around the core strengths of the network, the proposed architectural changes allow the tussle surrounding resource pooling to be drawn out without compromising the scalability and evolvability of the Internet.
pH-Induced Modulation of Vibrio fischeri Population Life Cycle

Commonly used as biological chemosensors in toxicity assays, Vibrio fischeri bacteria were systematically characterized using complementary physicochemical and biological techniques to elucidate the evolution of their properties under varying environmental conditions. Changing the pH above or below the optimal pH 7 was used to model the long-term stress that would be experienced by V. fischeri in environmental toxicology assays. The spectral shape of bioluminescence and cell-surface charge during the exponential growth phase were largely unaffected by pH changes. The pH-induced modulation of V. fischeri growth, monitored via the optical density (OD), was moderate. In contrast, the concomitant changes in the time-profiles of their bioluminescence, which is used as the readout in assays, were more significant. Imaging at discrete timepoints by scanning electron microscopy (SEM) and helium-ion microscopy (HIM) revealed that mature V. fischeri cells maintained a rod-shaped morphology with the average length of 2.2 ± 1 µm and diameter of 0.6 ± 0.1 µm. Detailed morphological analysis revealed subpopulations of rods having aspect ratios significantly larger than those of average individuals, suggesting the use of such elongated rods as an indicator of the multigenerational environmental stress. The observed modulation of bioluminescence and morphology supports the suitability of V. fischeri as biological chemosensors for both rapid and long-term assays, including under environmental conditions that can modify the physicochemical properties of novel anthropogenic pollutants, such as nanomaterials and especially stimulus-responsive nanomaterials.
Microcontroller-based fuzzy logic active filter for selective harmonic compensation

The half-bridge converter can be successfully employed as active filter in single-phase systems. The reduced number of semiconductor switches together with the need of balancing the capacitor voltages makes its control challenging especially if the aim is to have a simple digital algorithm easy to be implemented on an industrial microcontroller. Thus it has been chosen to adopt a fuzzy logic control the design of which is based on the dead-beat theory. The objective is to establish a link between the dead-beat control and the fuzzy logic control so as to provide dead-beat control with more intelligence and to reduce the trial and error attempts for the fuzzy controller tuning. The analysis developed and the consequent control include all the phenomena using no knowledge of the load, of the coupling filter or of the grid parameters thanks to the fuzzy logic computing. The proposed single phase active filter is controlled by the 7045F Hitachi microcontroller. Three techniques have been implemented in order to have a comparison: a classical hysteresis control and two predictive ones. The experimental results are discussed to better appreciate the impact of fuzzy logic in the design of controllers for low cost applications.
