Age Dependency of Successful Recanalization in Anterior Circulation Stroke: The ENDOSTROKE Study

Background: Clinical outcome after endovascular stroke therapy (EVT) for proximal anterior circulation stroke is often disappointing despite high recanalization rates. The ENDOSTROKE study aims to determine predictors of clinical outcome in patients undergoing EVT. Here we focus on the impact of age and recanalization on proximal middle cerebral artery (M1-MCA) or carotid T occlusion. Methods: ENDOSTROKE is an investigator-initiated, industrially independent multicenter registry launched in January, 2011, for consecutive patients undergoing EVT for large-vessel stroke. This analysis focuses on patients treated in 11 academic and nonacademic stroke centers with angiographically proven M1-MCA (n = 259) or carotid T occlusion (n = 103). Recanalization was defined as Thrombolysis in Myocardial Infarction (TIMI) score 2 or 3, and in patients with available Thrombolysis in Cerebral Ischemia (TICI) data (n = 309) as TICI scores 2b-3. Good outcome was defined as modified Rankin Scale (mRS) score of 0-2 assessed after 3 months or later. Results: The median age was 68 years (25th and 75th percentiles: 56, 76 years), and the median National Institutes of Health Stroke Scale (NIHSS) score at admission was 16 (13, 19); 41% of the patients had a favorable (mRS scores 0-2), and 59% had an unfavorable (mRS scores 3-6) outcome; 83% reached TIMI 2-3 flow. Independent predictors of good outcome were younger age, lower initial NIHSS scores, TIMI 2/3 recanalization and lower serum glucose levels. Outcome was highly dependent on patients' age: 60% of the patients within the lowest age quartile (range: 18-56 years) experienced good clinical outcome, decreasing stepwise over 47% (57-68 years) and 37% (69-76 years) to 17% in the highest age quartile (77-94 years). The proportion of patients with poor clinical outcome despite TIMI 2/3 recanalization (‘futile recanalization') increased dramatically from only 29% in the lowest age quartile over 34% and 40% (2nd and 3rd age quartiles) up to 53% in the highest age quartile. Results were similar in patients with available TICI scores, with ‘futile recanalization' rates increasing from 24% to 46% (lowest to highest age quartile). Conclusions: This study emphasizes the dramatic impact of patients' age on outcome in EVT for M1-MCA or carotid T occlusion, even in the presence of recanalization. Reasons for this age-related decrease in clinically successful recanalization rates urgently need clarification and may comprise patient-related factors (age-related increase in cardioembolic strokes, collateral status, comorbidities) as well as periprocedural issues (tortuous vessel anatomy in the elderly, age-dependent negative impact of general anesthesia in EVT).
A 24 GHz Zero-IF IQ-receiver using low-noise quadrature signal generation

This paper describes a 24GHz quadrature receiver (IQ-receiver) in 65 nm bulk CMOS technology. A 24GHz lumped coupler with open-terminated isolation port for lowest noise injection is developed for IQ-signal generation. The noise cancellation input matching network is adopted for the low noise amplifier (LNA) and mixers based on negative feedback transformers. By applying two-stage inverters, the receiver can properly operate with LO power even less than −10 dBm. The experimental results show a voltage conversion gain of 28.3 dB and a 5 dB noise figure at the IF frequency of 2MHz with an LO power of −10 dBm. The total chip area of the receiver is 0.66 mm2.
Social Capital and Organizational Performance: Exploring the Role of External Environment

In an effort to systematically review past research results, we conducted relative analysis examining the strength of the link between different social capital dimensions and organizational performance as well as potential moderators affecting this relationship. Analyses of past studies, we also found that this relationship depends on the social capital dimension considered, the institutional and industry contexts in which the organization operates. In this paper, we analysis the direct effect of social capital on organizational performance and deem that a main effect analysis providing an incomplete picture of performance implications of social capital. Internal resources and external environments are important to the development of a firm. Over all, our research contributes to a better understanding of social capital and organizational performance to explain variance in organizational performance.
Distributed control of Drinking Water Networks using population dynamics: Barcelona case study

Large-scale network systems involve a large number of variables, making the design of real-time controllers challenging. A distributed controller design allows to reduce computational requirements since tasks may be divided into different subsystems, making possible to guarantee real-time processing. This paper proposes a constrained optimization-based distributed control design by applying a novel population and masses dynamics approach. The distributed controller design is applied to the Barcelona Drinking Water Network (DWN) in order to illustrate its effectiveness in the control performance.
On minimal tests of sensor veracity for dynamic watermarking-based defense of cyber-physical systems

We address the problem of security of cyber-physical systems where some sensors may be malicious. We consider a multiple-input, multiple-output stochastic linear dynamical system controlled over a network of communication and computational nodes which contains (i) a controller that computes the inputs to be applied to the physical plant, (ii) actuators that apply these inputs to the plant, and (iii) sensors which measure the outputs of the plant. Some of these sensors, however, may be malicious. The malicious sensors do not report the true measurements to the controller. Rather, they report false measurements that they fabricate, possibly strategically, so as to achieve any objective that they may have, such as destabilizing the closed-loop system or increasing its running cost. Recently, it was shown that under certain conditions, an approach of “dynamic watermarking” can secure such a stochastic linear dynamical system in the sense that either the presence of malicious sensors in the system is detected, or the malicious sensors are constrained to adding a distortion that can only be of zero power to the noise already entering the system. The first contribution of this paper is to generalize this result to partially observed MIMO systems with both process and observation noises, a model which encompasses some of the previous models for which dynamic watermarking was established to guarantee security. This result, similar to the prior ones, is shown to hold when the controller subjects the reported sequence of measurements to two particular tests of veracity. The second contribution of this paper is in showing, via counterexamples, that both of these tests are needed in order to secure the control system in the sense that if any one of these two tests of sensor veracity is dropped, then the above guarantee does not hold. The proposed approach has several potential applications, including in smart grids, automated transportation, and process control.
Real-Time Intersession and Interrater Reliability of the Functional Movement Screen

Onate, JA, Dewey, T, Kollock, RO, Thomas, KS, Van Lunen, BL, DeMaio, M, and Ringleb, SI. Real-time intersession and interrater reliability of the functional movement screen. J Strength Cond Res 26(2): 408–415, 2012—The purpose of this study was to examine the real-time intersession and interrater reliability of the functional movement screen (FMS). The overall study consisted of 19 volunteer civilians (12 male, 7 female). The intersession reliability consisted of 12 men and 7 women, whereas 10 men and 6 women participated in the interrater reliability test session. Two raters (A and B) were involved in the interrater reliability aspect of this study. The FMS includes 7 tests: deep squat (DS), hurdle step (HS), in-line lunge (IL), shoulder mobility (SM), active straight leg raise (ASLR), trunk stability push-up (TSPU), and rotary stability (RS). Researchers analyzed the data via intraclass correlation (ICC). To determine the reliability of the intersession scoring of the FMS and the intrasession interrater scoring of the FMS a 2-way mixed effects model intraclass correlation coefficient (ICC3,1) was used for the continuous data, whereas a weighted Cohen's kappa (κ) was used for the categorical data. The dependent variables were FMS total score (0–21 scale) and associated tests were DS, HS, IL, SM, ASLR, TSPU, and RS. Intersession reliability (ICC, SEM) and κ were as follows: FMS total score (0.92, 0.51), DS (κ = 0.69), HS (κ = 0.16), IL (κ = 0.69), SM (κ = 0.84), ASLR (κ = 0.69), TSPU (κ = 0.77), and RS (no covariance). Interrater reliability (ICC, SEM) and κ were as follows: FMS total score (0.98, 0.25), DS (κ = 1.0), HS (κ = 0.33), IL (κ = 0.88), SM (κ = 0.90), ASLR (κ = 0.88), TSPU (κ = 0.75), and RS (no covariance). The FMS total scores displayed high intersession and interrater reliabilities. Finally, with the exception of HS, all tasks displayed moderate to high intersession reliability and good to high interrater reliability.
An interactive activation model of context effects in letter perception: Part 2. The contextual enhancement effect and some tests and extensions of the model.

The interactive activation model of context effects in letter perception is reviewed, elaborated, and tested. According to the model context aids the perception of target letters as they are processed in the perceptual system. The implication that the duration and timing of the context in which a letter occurs should greatly influence the perceptibility of the target is confirmed by a series of experiments demonstrating that early or enhanced presentations of word and pronounceablepseudoword contexts greatly increase the perceptibility of target letters. Also according to the model, letters in strings that share several letters with words should be equally perceptible whether they are orthographically regular and pronounceable (SLET) or irregular (SLNT) and should be much more perceptible than letters in contexts that share few letters with any word (XLQJ). This prediction is tested and confirmed. The basic results of all the experiments are accounted for, with some modification of parameters, although there are some discrepancies in detail. Several recent findings that seem to challenge the model are considered and a number of extensions are proposed.
Weighted principal component analysis based edge linking

As a complicated and troublesome research area, the edge detection is a fundamental step in terms of some image processing tasks including segmentation, compression and registration. In this study, we present a new approach for edge linking by applying the concept of the PCA on different types of images to determine the attractive edge segments. To determine the direction by using the angle information, the PCA decomposition is carried out on the block around the processed point. Specifically, the horizontal and vertical directions are taken into account by considering the angle between the eigenvectors corresponding to the largest and smallest eigenvalues. After making some experiments on noisy and noise free images, we have observed that the proposed method is robust to noise, preserves the structure of image and extracts well-localized and straight lines.
Mediators of the Link Between Childhood Sexual Abuse and Adult Depressive Symptoms

A history of childhood sexual abuse (CSA) is strongly associated with adult depression. The goal of the present study was to explore potential mediators of the CSA-depression link. The potential mediators were variables known to be associated with depression: interpersonal problems, gender role orientation, sociotropy, and self-silencing. The participants were 109 women and 83 men recruited from the community, approximately one third of whom had a history of CSA. The results indicated that gender role orientation, sociotropy, and self-silencing were not associated with a history of CSA. However, both men and women with a history of CSA reported more inter-personal problems than did individuals without this history. Whereas women reported being distant and controlling, men reported lacking assertiveness and taking too much responsibility in their relationships. These interpersonal variables partially mediated the link between CSA and depressive symptoms. Thus, in part, CSA survivors may be at risk for depression because they experience interpersonal problems.
Making Routing Robust to Changing Traffic Demands: Algorithms and Evaluation

Intra-domain traffic engineering can significantly enhance the performance of large IP backbone networks. Two important components of traffic engineering are understanding the traffic demands and configuring the routing protocols. These two components are inter-linked, as it is widely believed that an accurate view of traffic is important for optimizing the configuration of routing protocols, and through that, the utilization of the network. This basic premise, however, seems never to have been quantified. How important is accurate knowledge of traffic demands for obtaining good utilization of the network? Since traffic demand values are dynamic and illusive, is it possible to obtain a routing that is "robust" to variations in demands? We develop novel algorithms for constructing optimal robust routings and for evaluating the performance of any given routing on loosely constrained rich sets of traffic demands. Armed with these algorithms we explore these questions on a diverse collection of ISP networks. We arrive at a surprising conclusion: it is possible to obtain a robust routing that guarantees a nearly optimal utilization with a fairly limited knowledge of the applicable traffic demands
3D Model Retrieval

The topic of this paper is content-based retrieval of 3D models that are represented as triangle meshes. An object from some 3D geometry database can traditionally be accessed using attached structural information such as textual annotation. However, there are frequent requirements for a content-based retrieval of various multimedia contents. A content-based 3D model retrieval system has been implemented and this system is presented here. Models are retrieved by querying using another 3D model where the shape description for the query model is automatically created. The proposed feature vector is invariant with respect to translation, rotation and uniform scaling.
IMS/VS: An Evolving System

The Information Management System, IMS, began in the mid-1960s as a batch-only data base system that was known then as Data Language/I (DL/I). IMS was introduced in 1969 as IMS/360, a program product for the System/360. As the System/360 evolved into System/ 370, including support for virtual storage, the operating system evolved into OS/VS2, OS/VS2, and then MVS. At the same time, IMS evolved to become IMS/VS. The Information Management System has continued to be adapted to new requirements, especially those of interactive, on-line operations that require data communications. Recent advances in the following categories of IMS/VS functions are discussed in this paper: Fast Path, Data Sharing, System Logging, Data Base Recovery Control, on-line changes in system environment, Intersystem Communications, MVS Common Services Area usage, and architectural restructuring.
A Comparative study of Face Recognition with Principal Component Analysis and Cross-Correlation Technique

Automated face recognition has become a major field of interest. Face recognition algorithms are used in a wide range of applications viz., security control, crime investigation, and entrance control in buildings, access control at automatic teller machines, passport verification, identifying the faces in a given databases. This paper discusses different face recognition techniques by considering different test samples. The experimentation involved the use of Eigen faces and PCA (Principal Component Analysis). Another method based on Cross-Correlation in spectral domain has also been implemented and tested. Recognition rate of 90% was achieved for the above mentioned face recognition techniques.
Supergravity and a confining gauge theory: Duality cascades and χSB-resolution of naked singularities

We revisit the singular IIB supergravity solution describing M-fractional 3-branes on the conifold [hep-th/0002159]. Its 5-form flux decreases, which we explain by showing that the relevant = 1 SUSY SU(N+M) × SU(N) gauge theory undergoes repeated Seiberg-duality transformations in which N→N−M. Far in the IR the gauge theory confines; its chiral symmetry breaking removes the singularity of [hep-th/0002159] by deforming the conifold. We propose a non-singular pure-supergravity background dual to the field theory on all scales, with small curvature everywhere if the `t Hooft coupling gsM is large. In the UV it approaches that of [hep-th/0002159], incorporating the logarithmic flow of couplings. In the IR the deformation of the conifold gives a geometrical realization of chiral symmetry breaking and confinement. We suggest that pure = 1 Yang-Mills may be dual to strings propagating at small gsM on a warped deformed conifold. We note also that the standard model itself may lie at the base of a duality cascade.
Avian Color Vision and Coloration: Multidisciplinary Evolutionary Biology

A fundamental issue in biology is explaining the diversity of coloration found in nature. Birds provide some of the best‐studied examples of the evolution and causes of color variation and some of the most arresting color displays in the natural world. They possess perhaps the most richly endowed visual system of any vertebrate, including UV‐A sensitivity and tetrachromatic color vision over the 300–700‐nm waveband. Birds provide model systems for the multidisciplinary study of animal coloration and color vision. Recent advances in understanding avian coloration and color vision are due to recognition that birds see colors in a different way than humans do and to the ready availability of small spectrometers. We summarize the state of the current field, recent trends, and likely future directions.
Complete Genome Sequence of a New Member of the Marseilleviridae Recovered from the Brackish Submarine Spring in the Cassis Port-Miou Calanque, France

ABSTRACT Marseilleviridae is a rapidly expanding family of Acanthamoeba-infecting large DNA viruses distributed worldwide. We report here the complete 349-kbp genome sequence of Port-Miou virus, which is surprisingly close to that of Lausannevirus (isolated from the Seine River upstream from Paris, France), despite the strong dissimilarities of their sampling locations.
Incidence of Subsequent Vertebral Fracture after Kyphoplasty

Study Design. A retrospective review of charts and radiographs of all consecutive patients who underwent kyphoplasty at the authors’ center from the initial procedure in September 2000 to the end of the collection period in July 2002. Summary of Background Data. The best available natural history data would suggest that after experiencing an osteoporotic vertebral compression fracture, patients have a 19% incidence of subsequent fracture in the following year when no surgical intervention is performed. When kyphoplasty is performed, there are conflicting data regarding the incidence of subsequent fracture, ranging anywhere from 3 to 29%. These fractures occur at adjacent levels between 30 and 90% of the time, with no clear explanation for the wide variation in the results of three different studies. There are biomechanical data to suggest that injection of cement does increase the stiffness of the treated vertebra and that this increases strain on adjacent vertebrae, especially in forward bending. Methods. A database was created containing patient age, gender, height, weight, medication history, comorbidities, fracture levels, and pain level before and after surgery. Subsequent fractures were confirmed with radiographs and MRI. Statistical analysis was performed. Results. Thirty-eight patients (10 men and 28 women) were treated for 47 levels initially. L1 and L2 were the most common level of fracture managed initially. The gender, smoking and medication history, location of fracture, and number of fracture levels of the patients did not correlate with the risk of subsequent fracture. Over the follow-up period (average, 8 months), 10 patients sustained 17 subsequent fractures. Eight patients sustained fractures in the first 2 months after the index procedure, all with at least one fracture at an adjacent level. Of the 17 subsequent fractures, there were nine at the adjacent-above levels, four at adjacent-below levels, and four at remote levels. The remote fractures occurred at significantly greater time intervals after the index procedure (P < 0.001). Conclusion. This study demonstrated a higher rate of subsequent fracture after kyphoplasty compared with natural history data for untreated fractures. Most of these occurred at an adjacent level within 2 months of the index procedure. After this 2-month period, there were only occasional subsequent fractures, which occurred at remote levels. This confirms biomechanical studies showing that cement augmentation places additional stress on adjacent levels. Patients with an increase in back pain after kyphoplasty should be evaluated carefully for subsequent adjacent fractures, especially during the first 2 months after the index procedure.
Parsing Natural Language Sentences by Semi-supervised Methods

We present our work on semi-supervised parsing of natural language sentences, focusing on multi-source crosslingual transfer of delexicalized dependency parsers. We first evaluate the influence of treebank annotation styles on parsing performance, focusing on adposition attachment style. Then, we present KLcpos3, an empirical language similarity measure, designed and tuned for source parser weighting in multi-source delexicalized parser transfer. And finally, we introduce a novel resource combination method, based on interpolation of trained parser models.
Emergency contraceptive pills: knowledge and attitudes of pharmacy personnel in Managua, Nicaragua.

CONTEXT As abortion is illegal in Nicaragua, postcoital contraception is an important option for preventing pregnancy. Emergency contraceptive pills are available in Nicaraguan pharmacies over the counter, but pharmacy personnel's knowledge and attitudes about this method can affect access. METHODS A cross-sectional survey was conducted in Managua, Nicaragua's capital. Interviewers administered a semistructured questionnaire to 93 pharmacy employees to determine their knowledge of and attitudes toward emergency contraceptive pills. Descriptive statistics and cross-tabulations were used to examine responses of and differences between male and female employees. RESULTS All participants knew about emergency contraceptive pills and reported experience selling them. The majority sold them at least once a week (92%), usually without a prescription (97%). Of participants who were aware that emergency contraceptive pills should be taken only after sexual intercourse, 45% knew that the pills can be taken up to three days afterward; none knew that the pills are effective up to five days afterward. More than one-third of all respondents (39%) thought the pills can induce abortion, and most overestimated contraindications and side effects. Large majorities believed the availability of emergency contraceptive pills discourages use of ongoing methods (75%), encourages sexual risk-taking (82%) and increases transmission of HIV and other STIs (76%). Sixty-three participants (68%) thought emergency contraceptive pills are necessary to reduce unwanted and unplanned pregnancy; 65% were willing to provide them to all women in need, although only 13% would provide them to minors. CONCLUSIONS Managuan pharmacy personnel frequently dispense emergency contraceptive pills, but need additional education to accurately counsel women about the method.
