Parameterization and Validation of an Integrated Electro-Thermal Cylindrical LFP Battery Model

In this paper, for the first time, an equivalent circuit electrical model is integrated with a two-state thermal model to form an electro-thermal model for cylindrical lithium ion batteries. The parameterization of such model for an A123 26650 LiFePO4 cylindrical battery is presented. The resistances and capacitances of the equivalent circuit model are identified at different temperatures and states of charge (SOC), for charging and discharging. Functions are chosen to characterize the fitted parameters. A two-state thermal model is used to approximate the core and surface temperatures of the battery. The electrical model is coupled with the thermal model through heat generation and the thermal states are in turn feeding a radially averaged cell temperature affecting the parameters of the electrical model. Parameters of the thermal model are identified using a least squares algorithm. The electro-thermal model is then validated against voltage and surface temperature measurements from a realistic drive cycle experiment.
Comparison between piperacillin/tazobactam and cefepime monotherapies as an empirical therapy for febrile neutropenia in children with hematological and malignant disorders: A prospective, randomized study.

To evaluate the efficacy and safety of piperacillin/tazobactam (PIPC/TAZ) or cefepime (CFPM) monotherapy for febrile neutropenia (FN) in children, a total of 53 patients with 213 febrile episodes were randomly treated with either PIPC/TAZ 337.5 mg/kg/day, or CFPM 100 mg/kg/day. No significant differences were observed in the success rates of the PIPC/TAZ and CFPM treatments (62.1% vs. 59.1%, P = 0.650). Furthermore, no differences were noted in the rates of new infection and mortality, and no serious adverse effects occurred in either of groups. Both PIPC/TAZ and CFPM were effective and safe as an empirical therapy for FN in children. Pediatr Blood Cancer 2015;62:356-358. © 2014 Wiley Periodicals, Inc.
MR of CNS sarcoidosis: correlation of imaging features to clinical symptoms and response to treatment.

BACKGROUND AND PURPOSE
Sarcoidosis is an idiopathic systemic granulomatous disease, recognized in a patient when clinical and radiologic findings are confirmed by histopathologic analysis. The objective was to identify a relationship between MR imaging and clinical findings in CNS sarcoidosis.


METHODS
The clinical charts of 461 patients with biopsy-proved sarcoidosis were reviewed retrospectively. Criteria for including patients in the study included those with symptoms referable to the CNS, excluding those with another explanation for their symptoms, those with headaches or other subjective complaints without accompanying objective findings, and those with peripheral neuropathy other than cranial nerve involvement or myopathy without CNS manifestations. Thirty-four of 38 patients whose conditions met the criteria for CNS sarcoidosis underwent a total of 82 MR examinations. The positive imaging findings were divided into categories as follows: pachymeningeal, leptomeningeal, nonenhancing brain parenchymal, enhancing brain parenchymal, cranial nerve, and spinal cord and nerve root involvement. Treatment response, clinical symptomatology, and any available histopathologic studies were analyzed with respect to imaging manifestations in each of the categories.


RESULTS
Eighty-two percent of the patients with sarcoidosis with neurologic symptoms referable to the CNS had findings revealed by MR imaging. However, eight (40%) of 20 cranial nerve deficits seen at clinical examination of 13 patients were not seen at contrast-enhanced MR imaging, and 50% of the patients with symptoms referable to the pituitary axis had no abnormal findings on routine contrast-enhanced MR images. In contradistinction, 44% of 18 cranial nerves in nine patients with MR evidence of involvement had no symptoms referable to the involved cranial nerve. Clinical and radiologic deterioration occurred more commonly with leptomeningeal and enhancing brain parenchymal lesions.


CONCLUSION
MR imaging can be used to confirm clinical suspicion and to show subclinical disease and the response of pathologic lesions to treatment.
Mechanical Properties versus Morphology of Ordered Polymers. Volume 2.

Abstract : Morphological techniques in conjunction with meachanical testing have been employed to elucidate the relationships between mechanical properties of rigid rod polymer fiber and file with sample microstructures and to use this knowledge to obtain the maximum in strength and modulus for these materials. The fibers and films of poly(p-phenylene benzobisthiazole) (PBT) which have been investigated were produced at Carnegie Mellon Uni and at Celanese Research Corp from liquid crystalline solutions using dry-jet-wet spin process for fibers and either shear or extrusion for films. Correlation of sample microstructure and resultant mechanical properties with processing conditions has been done to help optimize processing conditions. Spectroscopic students suggest that the polymers in solution exist in the protonated form. While most of the materials produced to date have extremely high degrees of orientation, thus, far, the key differences have been in the lateral ordering of the chains. Better laterial ordering has been observed in heat treated samples, and in particular, samples processed directly from the polymerization solvent, polyphosphoric acid, but no true 3-dimensional crystal structure is formed. It remains to be seen if this feature is a direct consequence of the chemical structure of PBT molecules or is simply the result of non-optimized processing and heat treatment conditions. The suprisingly nonlinear behavior and apparent plasticity of the as-spun fibers and the modulus increase after plastic deformation caused considerable concern. These effects are caused by microstructural element buckling due to residual stresses produced during the fiber formation process.

Intra-articular hyaluronan injections for the treatment of osteoarthritis of the knee: a randomized, double blind, placebo controlled study.

OBJECTIVE
Hyaluronic acid (HA) polymers have been found to be useful as viscosupplements for the treatment of osteoarthritis (OA) in a number of clinical studies. It appears that HA with high molecular weights (HMW) are more effective than low molecular weight HA polymers.


METHODS
A single blind, initial randomized study was conducted involving two randomly selected patient groups, which received injections of either placebo or BioHy, a highly purified HMW HA produced by bacterial fermentation. HA was administered intra-articularly and several functional tests, including pain level, stiffness, and physical function, were used to score efficacy at various intervals throughout the study.


RESULTS AND CONCLUSION
The results through week 20 indicate that BioHy provides relief for osteoarthritic patients without causing adverse effects, although the study was not sufficiently powered to obtain statistically significant differences between the treatment groups.
Consumer perception of interface quality, security, and loyalty in electronic commerce

Customer interface quality, perceived security, and customer loyalty are critical factors for success of an e-commerce website; however, the relationships among them are not fully understood. We proposed a model for testing the relationships among them and the important outcomes of the site: switching costs and customer loyalty. Data was collected to test the model using a web-based survey, and empirical analyses were performed using SEM. The analytical results demonstrated that customer interface quality and perceived security positively affected customer satisfaction and switching costs, and thus customer loyalty to an e-commerce website. Specifically, our study showed that switching costs positively moderated the effect of customer satisfaction on customer loyalty; this moderating effect is discussed.

Comparative Study of Different CPU Scheduling Algorithms Miss .

In Multiprogramming operating system, CPU scheduling plays a very important role. CPU scheduling deals with the problem that to which process the CPU should be allocated. For scheduling the processes in different ways, there are many different scheduling algorithms. This article deals with various scheduling algorithms like First-Come-First-Serve (FCFS) scheduling algorithm, Shortest Job First (SJF) scheduling algorithm, Priority scheduling algorithm, Round Robin (R-R) scheduling algorithm, Multilevel Queue scheduling algorithm and Multilevel Feedback Queue scheduling algorithm. FCFS scheduling algorithm is based on First-in-first-out concept and is non-pre-emptive scheduling algorithm. It is generally suitable for batch systems. SJF scheduling algorithm can be either pre-emptive or non-pre-emptive and it is based on burst time of the processes. Priority scheduling algorithm is necessarily a form of pre-emptive scheduling algorithm and it is based on the priorities given to the processes. R-R scheduling algorithm is also a pre-emptive scheduling algorithm and is based on the given time-quantum. It is generally suitable for time sharing systems. In multilevel queue scheduling, when the process enters in the system, it is permanently assigned to a queue depending upon its nature. It is pre-emptive in nature. Multilevel feedback queue is also pre-emptive and it allows the processes to move between queues.

Consideration of high-sensitivity troponin values below the 99th percentile at presentation: does it improve diagnostic accuracy?

BACKGROUND
The introduction of high-sensitivity cardiac troponin (hs-cTn) assays allows the assessment of clinical decision values below the 99th percentile.


METHODS
Final diagnosis and one-year mortality were adjudicated in a multicenter, prospective cohort of 1181 patients presenting with acute chest pain to the emergency department. Hs-cTnT (Roche) and cTnI-ultra (Siemens) were measured in a blinded fashion.


RESULTS
At presentation hs-cTnT and cTnI-ultra were below the limit of blank (LOB) in 201 (17%) and 549 (47%) patients, below the 75th percentile in 379 (32%) and 623 (53%) patients, below the 95th percentile in 603 (51%) and 808 (68%), and below the 99th percentile in 748 (63%) and 913 (77%), respectively. Sensitivities for the diagnosis of AMI were 100.0% and 96.8% respectively for hs-cTnT and cTnI-ultra (LOB as cut-off value), 99.5% and 96.2% (75th percentile), 96.8% and 93.0% (95th percentile), and 94.1% and 88.1% (99th percentile). The proportion of patients correctly classified as having or not AMI increased from 32.9% (LOB as cut-off value) to 47.8% (75th percentile), 65.9% (95th percentile) and 77.3% (99th percentile) for hs-cTnT and from 61.2% to 67.3%, 81.9% and 89.3% respectively for cTnI-ultra. At 1 year, all-cause mortality was very low and similar for patients below all of these cut-off levels (between 0.7% and 1.5%, p=0.748 for all-groups comparison).


CONCLUSION
cTn should be considered as a continuous variable. Decision values below the 99th percentile (e.g. the 75th percentile) are associated with a very high NPV for the diagnosis of AMI, but have a lower accuracy than the 99th percentile.
Evaluation of Text Classification Algorithms for a Web-based Market Data Warehouse

Decision makers in enterprises cannot handle information flooding without serious problems. A market data information system (MAIS), which is the foundation of a decision support system for German energy trading, uses search and filter components to provide decision-relevant information from Web-documents for enterprises. The already implemented filter component in form of a Multilayer Perceptron has to be benchmarked against different existing algorithms to enhance the classification of text documents. An evaluation environment with appropriate algorithms is developed for this purpose. Also a set of test data is provided and a tool selection is shown which implement different text mining algorithms for classification. The benchmark results will be shown in the paper.
Left ventricular systolic function and the pattern of late-gadolinium-enhancement independently and additively predict adverse cardiac events in muscular dystrophy patients

BACKGROUND
Cardiac involvement is a frequent finding in patients with Duchenne (DMD) and Becker (BMD) muscular dystrophies. With this study, we aimed at elucidating the relationship between the phenotypic expression of cardiac involvement and the occurrence of adverse cardiac events in DMD/BMD patients.


METHODS
Eighty-eight male DMD/BMD patients (age 29 ± 14 yrs) were prospectively enrolled. All patients underwent cardiovascular magnetic resonance (CMR) comprising cine- and late-gadolinium-enhancement (LGE)-CMR at study entry and were subsequently followed-up for adverse cardiac events. The primary endpoint was defined as all-cause/cardiac death or cardiac transplantation. Secondary endpoints were (1) hospitalization for heart failure and/or (2) occurrence of non-/sustained ventricular tachycardia (VT).


RESULTS
During a mean follow-up time of 47 ± 18 months, the primary endpoint was observed in three (3%) and the secondary endpoint in 21 (24%) patients. On multivariable analysis, LV-EF (HR, 95% CI: 0.94, 0.89-0.97, p = 0.001) and the presence of "transmural" LGE (HR, 95% CI: 2.89, 1.09-7.68, p = 0.033) were the only independent predictors for secondary endpoints. A cut-off for LV-EF of 45% was associated with the highest hazard ratio (HR, 95% CI: 11.50, 4.49-29.43, p < 0.0001) in a Cox regression survival analysis. In the group of patients with a LV-EF (>45%), those patients already showing "transmural" LGE had a significantly lower event-free-survival (HR, 95% CI: 13.48, 1.89-96.12, p = 0.009) compared to those without.


CONCLUSIONS
An impaired LV systolic function (LV-EF ≤45%) and a "transmural" pattern of myocardial fibrosis independently predict the occurrence of adverse cardiac events in DMD/BMD patients. Even in DMD/BMD patients with relatively preserved LV-EF (>45%), the simple and visually assessable parameter "transmural LGE" is of additive prognostic value.

Which patients improve the most after arthritis rehabilitation? A study of predictors in patients with inflammatory arthritis in Northern Europe, the STAR-ETIC collaboration.

OBJECTIVE
To study health-related quality of life (HRQoL) in arthritis rehabilitation performed by multidisciplinary teams in patients with chronic inflammatory arthritis. Predictors of change in health-related quality of life and the proportion of patients with clinical improvement were investigated.


DESIGN
Multicentre prospective observational study in 4 European countries.


METHODS
HRQoL was measured with the European Quality 5 Dimensions (EQ-5D) and the Short Form 36 Health Survey (SF-36) in 731 patients who underwent multidisciplinary rehabilitation. Potential predictors were physical functioning (Health Assessment Questionnaire (HAQ)), self-efficacy (Arthritis Self Efficacy Scale (ASES)), psychological health (Hopkins Symptom Check List (HSCL-25)), pain/fatigue (numeric rating scales (NRS)), age, sex, diagnosis, comorbidity, education, clinical setting and change of medication during rehabilitation. Analysis of covariance (ANCOVA) was used to assess for potential predictors and interactions. The minimal important differences for HRQoL were analysed.


RESULTS
Reporting worse function (b 0.05, p = 0.01), less psychological well-being (b 0.09, p = 0.000), and experiencing more pain (b 0.03, p = 0.000) or fatigue (b 0.02, p = 0.000) at admission predicted improved HRQoL. Change in medication during rehabilitation (b 0.08, p = 0.013) was associated with greater improvement in HRQoL. These EQ-5D findings were supported by SF-36 findings. Positive minimal important differences were noted in 46% (EQ-5D) and 23-47% (SF-36 subscales) of the patients.


CONCLUSION
Patients with more severe symptoms experienced the largest gain in HRQoL post-intervention. The results of this study are of value for selecting the right patients for rheumatological team rehabilitation.
Active filters with control based on the p-q theory

Due the intensive use of power converters and other non-linear loads in industry and by consumers in general, it can be observed an increasing deterioration of the power systems voltage and current waveforms. The presence of harmonics in the power lines results in greater power losses in distribution, interference problems in communication systems and, sometimes, in operation failures of electronic equipments, which are more and more sensitive since they include microelectronic control systems, which work with very low energy levels. Because of these problems, the issue of the power quality delivered to the end consumers is, more than ever, an object of great concern. International standards concerning electrical power quality (IEEE-519, IEC 61000, EN 50160, among others) impose that electrical equipments and facilities should not produce harmonic contents greater than specified values, and also specify distortion limits to the supply voltage. Meanwhile, it is mandatory to solve the harmonic problems caused by those equipments already installed. Passive filters have been used as a solution to solve harmonic current problems, but they present several disadvantages, namely: they only filter the frequencies they were previously tuned for; their operation cannot be limited to a certain load; resonances can occur because of the interaction between the passive filters and other loads, with unpredictable results. To cope with these disadvantages, recent efforts have been concentrated in the development of active filters.
An Arithmetic Logic Unit design based on reversible logic gates

In this paper, a design constructing the Arithmetic Logic Unit(ALU) based on reversible logic gates as logic components is proposed. By using reversible logic gates instead of using traditional logic gates such as AND gates and OR gates, a reversible ALU whose function is the same as the traditional ALU is constructed. The presented reversible ALU reduces the information bits' use and loss by reusing the logic information bits logically and realizes the goal of lowering power consumption.

A modified stochastic neighbor embedding for multi-feature dimension reduction of remote sensing images

In automated remote sensing based image analysis, it is important to consider the multiple features of a certain pixel, such as the spectral signature, morphological property, and shape feature, in both the spatial and spectral domains, to improve the classification accuracy. Therefore, it is essential to consider the complementary properties of the different features and combine them in order to obtain an accurate classification rate. In this paper, we introduce a modified stochastic neighbor embedding (MSNE) algorithm for multiple features dimension reduction (DR) under a probability preserving projection framework. For each feature, a probability distribution is constructed based on t-distributed stochastic neighbor embedding (t-SNE), and we then alternately solve t-SNE and learn the optimal combination coefficients for different features in the proposed multiple features DR optimization. Compared with conventional remote sensing image DR strategies, the suggested algorithm utilizes both the spatial and spectral features of a pixel to achieve a physically meaningful low-dimensional feature representation for the subsequent classification, by automatically learning a combination coefficient for each feature. The classification results using hyperspectral remote sensing images (HSI) show that MSNE can effectively improve RS image classification performance. 2013 International Society for Photogrammetry and Remote Sensing, Inc.

Caching in information centric networking: A survey

Internet usage has drastically shifted from host-centric end-to-end communication to receiver-driven content retrieval. In order to adapt to this change, a handful of innovative information/content centric networking (ICN) architectures have recently been proposed. One common and important feature of these architectures is to leverage built-in network caches to improve the transmission efficiency of content dissemination. Compared with traditional Web Caching and CDN Caching, ICN Cache takes on several new characteristics: cache is transparent to applications, cache is ubiquitous, and content to be cached is more ine-grained. These distinguished features pose new challenges to ICN caching technologies. This paper presents a comprehensive survey of state-of-art techniques aiming to address these issues, with particular focus on reducing cache redundancy and improving the availability of cached content. As a new research area, this paper also points out several interesting yet challenging research directions in this subject. 2013 Elsevier B.V. All rights reserved.
