Real-time simulation for acoustic feedback cancellation algorithms: An hybrid PC/C6713-DSK based implementation

The present paper deals with the Acoustic Feedback Cancellation problem and proposes a real-time implementation on Texas Instruments C6713 DSK board of two AFC algorithms, one patented and the other recently appeared in the literature. Different approaches have been followed for their porting to target, in relationship with the domain they have been originally formulated (time and frequency respectively). Their performances are discussed and compared, thus providing a useful reference for scientist and engineers interested in real-time AFC applications. Moreover, moving from a previous work of the same authors on a PC-based real-time AFC system, this work also describes an hybrid PC/DSP real-time system for AFC simulation and testing. In such a system the PC and the DSP board (our TI C6713 DSK) are looped together: the former is devoted to room simulation whereas the latter accomplishes the speech reinforcement and feedback cancellation tasks.
Postarthroscopy Analgesia with Intraarticular Bupivacaine/Morphine: A Randomized Clinical Trial

Background:Postarthroscopy analgesia has been provided with intraarticular bupivacaine, but the duration of analgesia may be only a few hours. More recently, longer-lasting analgesia has been achieved using intraarticular morphine, although the onset of analgesia may be delayed. The combination of intraarticular morphine and bupivacaine has been suggested as an ideal analgesic after knee arthroscopy. Methods:One hundred and twenty ASA Physical Status 1–2 outpatients, age 18–60 yr, having knee arthroscopy, were randomized into one of four treatment groups. Exclusion criteria included relevant drug allergy, extensive debridement or synovectomy, arthrotomy, postoperative intraarticular drainage, tracheal intubation, and patient refusal. All patients received general anesthesia with intravenous fentanyl, propofol, N2O, O2, and isoflurane. At the end of surgery, before tourniquet release, the following were injected intraarticularly through the arthroscope: group 1, 0.25% bupivacaine; group 2, 1 rag morphine in saline; group 3, 2 mg morphine in saline; and group 4, 1 mg morphine in 0.25% bupivacaine. The volume injected was 30 ml, and all solutions contained 1:200,000 epinephrine. Postoperative analgesia was provided with intravenous fentanyl and/or oral acetaminophen/codeine, and was recorded for 24 h. Visual analog pain scale (VAPS) scores and the McGill Pain Questionnaire (MPQ) were performed hourly from 1–6 h, and at 24 h postoperatively. Results:Visual analog pain scale and MPQ scores were lowest in groups 1 and 4 at 1–6 h, but at 24 h, VAPS scores were lowest in groups 2, 3, and 4. Analgesic requirements were lower for the first 12 h in groups 1 and 4, but no difference was seen between groups over the 24-h study period. No adverse effects were noted. Conclusions:Morphine, 1 mg intraarticular, in 30 ml 0.25% bupivacaine, with 1:200,000 eplnephrine, may provide superior postoperative analgesia for up to 24 h versus bupivacaine or morphine alone.
HUMAN 2 AGGRESSION METHODOLOGY IN THE STUDY OF AGGRESSION : INTEGRATING THEORIES , RESEARCH , EXPERIMENTAL AND AND IMPLICATIONS FOR SOCIAL POLICY NONEXPERIMENTAL FINDINGS

@ Now consider the following description of a laboratory aggression experiment. In this experiment (Zimbardo, 1969), college women were told that the researchers were studying "empathic responses to strangers. " Individuals participated in groups of four. By the flip of a coin, participants were assigned to anonymous or identifiable conditions. In the anonymous condition, participants wore large laboratory coats, wore hoods over their heads, and were not referred to by name. In the identifiable condition, participants did not wear laboratory coats, wore large name tags, and were referred to by name. The room lights were turned off in the anonymous condition or only dimmed in the identifiable condition. Participants then listened to one of two tape-recorded interviews between the experimenter and another "participant" (who was actually an accomplice to the experimenter). In one of the tapes, the accomplice behaved in a nice, altruistic, and accepting manner. In the other tape, she behaved in an obnoxious, self-centered, and critical manner.

The Actiheart in adolescents: a doubly labelled water validation.

BACKGROUND/OBJECTIVE This study investigated the validity of the Actiheart device for estimating free-living physical activity energy expenditure (PAEE) in adolescents. SUBJECTS/METHODS Total energy expenditure (TEE) was measured in eighteen Canadian adolescents, aged 15-18 years, by DLW. Physical activity energy expenditure was calculated as 0.9 X TEE minus resting energy expenditure, assuming 10% for the thermic effect of feeding. Participants wore the chest mounted Actiheart device which records simultaneously minute-by-minute acceleration (ACC) and heart rate (HR). Using both children and adult branched equation modeling, derived from laboratory-based activity, PAEE was estimated from the ACC and HR data. Linear regression analyses examined the association between PAEE derived from the Actiheart and DLW method where DLW PAEE served as the dependent variable. Measurement of agreement between the two methods was analyzed using the Bland-Altman procedure. RESULTS A nonsignificant association was found between the children derived Actiheart and DLW PAEE values (R = .23, R(2) = . 05, p = . 36); whereas a significant association was found between the adult derived Actiheart and DLW PAEE values (R = .53, R(2) = . 29, p < . 05). Both the children and adult equation models lead to overestimations of PAEE by the Actiheart compared with the DLW method, by a mean difference of 31.42 kcal.kg(-1). d(-1) (95% limits of agreement: -45.70 to -17.15 kcal.kg(-1). d(-1) and 9.80 kcal.kg(-1). d(-1) (95% limits of agreement: -21.22-1.72 kcal.kg(-1). d(-1)), respectively. CONCLUSION There is relatively poor measurement of agreement between the Actiheart and DLW for assessing free-living PAEE in adolescents. Future work should develop group based branched equation models specifically for adolescents to improve the utility of the device in this population.
Modeling smoking cessation data with alternating states and a cure fraction using frailty models

We propose a flexible parametric model to describe alternating states recurrent‐event data where there is a possibility of cure with each type of event. We begin by introducing a novel cure model in which a common frailty influences both the cure probability and the hazard function given not cured. We then extend our model to data with recurring events of two alternating types. We assume that each type of event has a gamma frailty, and we link the frailties by a Clayton copula. We illustrate the model with an analysis of data from two smoking cessation trials comparing bupropion and placebo, in which each subject potentially experienced a series of lapse and recovery events. Our analysis suggests that bupropion increases the probability of permanent cure and decreases the hazard of lapse, but does not affect the distribution of time to recovery during a lapse. The data suggest a positive but non‐significant association between the lapse and recovery frailties. A simulation study suggests that the estimates have little bias and that their 95 per cent confidence intervals have nearly nominal coverage in samples of practical size.

AFFINE PROJECTION ALGORITHMS WITH VARIABLE REGULARIZATION

We propose two new affine projection algorithms (APA) with variable regularization parameter. The proposed algorithms dynamically update the regularization parameter that is fixed in the conventional regularized APA (R-APA) using a gradient descent based approach. By introducing the normalized gradient, the proposed algorithms give birth to an efficient and a robust update scheme for the regularization parameter. Through experiments we demonstrate that the proposed algorithms outperform conventional R-APA in terms of the convergence rate and the misadjustment error.
Autofocusing of inverse synthetic aperture radar images using contrast optimization

A number of autofocusing techniques are proposed for motion compensation in inverse synthetic aperture radar (ISAR) imaging of objects. These techniques are based on the optimization of a contrast function, which represents a measure of the degree of focus of the image. Three novel image contrast functions are defined and the main steps of the autofocusing algorithm are described. A comparison of the behavior of the proposed techniques is performed analyzing some results obtained from simulation of realistic targets.
Super-resolution reconstruction based on multisource bidirectional similarity and non-local similarity matching

A novel super-resolution (SR) reconstruction algorithm based on multisource bidirectional similarity and non-local similarity matching for multi-exposure dynamic image sequences is proposed in this study. First, luminance compensation for multi-exposure dynamic images is implemented based on multisource bidirectional similarity. Then, combining a self-adaptive regional correlation evaluation strategy and a weighting strategy based on pseudo-Zernike moment feature similarity and structural similarity yields a novel and robust non-local similarity matching scheme (PZ-NSM) to learn non-local similarity priors between low- and high-resolution dynamic image patches at different spatio-temporal scales without additional training. Finally, SR reconstruction is implemented based on PZ-NSM and spatio-temporal trans-scale fusion of non-local similarities between dynamic images. The proposed algorithm does not rely on accurate estimation of subpixel motion and can therefore be adapted to more complex motion patterns. It has high rotation invariance effectiveness and is robust to noise and illumination. Experimental results demonstrate that the proposed algorithm outperforms existing algorithms in terms of both subjective and objective evaluations.
A Late Iron Age Fortress North of Jerusalem

Studies dealing with the defensive system of the Kingdom of Judah in the Late Iron Age have mentioned the fortress excavated at the French Hill, north of Jerusalem (the possibility of its use during the Persian period has also been raised). The plan and finds from this fortress have never been published, and its description has appeared in a very preliminary form. This article is the final report of the excavation carried out 33 years ago by Professor Ora Negbi, to whom we dedicate this article. Aside from a fully detailed publication of the fortress's architectural plan and the finds retrieved, our objectives are to set the chronological framework on the basis of the finds, suggest a possible geographical-historical identification according to biblical sources, and attempt to reconstruct the defensive system of the Judaean kingdom's capital-Jerusalem.

Complexes of the tripodal phosphine ligands PhSi(XPPh2)3 (X = CH2, O): synthesis, structure and catalytic activity in the hydroboration of CO2.

The coordination chemistry of Fe(2+), Co(2+) and Cu(+) ions was explored with the triphosphine and triphosphinite ligands PhSi{CH2PPh2}3 (1) and PhSi{OPPh2}3 (2), so as to evaluate the impact of the electronic properties of the tripodal phosphorus ligands on the structure and reactivity of the corresponding complexes. The synthesis and characterization of the complexes [Fe(κ(3)-PhSi{CH2PPh2}3)(MeCN)3][OTf]2 (3) (OTf = O3SCF3), [Fe(κ(3)-PhSi{OPPh2}3)(MeCN)3][OTf]2 (3'), [Co(κ(2)-PhSi{CH2PPh2}3)Cl2] (4), [Co(κ(3)-PhSi{OPPh2}3)Cl2] (4'), [Cu(κ(3)-PhSi{CH2PPh2}3)Br] (5) and [Cu(κ(3)-PhSi{OPPh2}3)I] (5') were carried out. The crystal structures of 3, 3', 4, 4', and of the solvates 5·3THF and 5'·THF are reported. Complexes 3-5' were shown to promote the catalytic hydroboration of CO2 with (9-BBN)2 (9-BBN = 9-borabicyclo[3.3.1]nonane). While the iron and cobalt complexes of the triphosphine 1 are more active than the analogous complexes with 2, the opposite trend is observed with the copper catalysts. Overall, the copper catalysts 5 and 5' are both more reactive and more selective than the Fe and Co catalysts, enabling the formation of the acetal H2C(OBBN)2 with a high molar ratio of H2C(OBBN)2 : CH3OBBN up to 92 : 8.
Improving network anomaly detection via selective flow-based sampling

Sampling has become an essential component of scalable Internet traffic monitoring and anomaly detection. A new flow-based sampling technique that focuses on the selection of small flows, which are usually the source of malicious traffic, is introduced and analysed. The proposed approach provides a flexible framework for preferential flow sampling that can effectively balance the tradeoff between the volume of the processed information and the anomaly detection accuracy. The performance evaluation of the impact of selective flow-based sampling on the anomaly detection process is achieved through the adoption and application of a sequential non-parametric change-point anomaly detection method on realistic data that have been collected from a real operational university campus network. The corresponding numerical results demonstrate that the proposed approach achieves to improve anomaly detection effectiveness and at the same time reduces the number of selected flows.
Algorithms for the min-max regret generalized assignment problem with interval data

Many real life optimization problems do not have accurate estimates of the problem parameters at the optimization phase. For this reason, the min-max regret criteria are widely used to obtain robust solutions. In this paper we consider the generalized assignment problem (GAP) with min-max regret criterion under interval costs. We show that the decision version of this problem is Σp2-complete. We present two heuristic methods: a fixed-scenario approach and a dual substitution algorithm. For the fixed-scenario approach, we show that solving the classical GAP under a median-cost scenario leads to a solution of the min-max regret GAP whose objective function value is within twice the optimal value. We also propose exact algorithms, including a Benders' decomposition approach and branch-and-cut methods which incorporate various methodologies, including Lagrangian relaxation and variable fixing. The resulting Lagrangian-based branch-and-cut algorithm performs satisfactorily on benchmark instances.
Received signal strength–based localization for large space indoor environments

WiFi-based indoor localization has attracted recent research attention. Large space layout is a special and more complex indoor environment. Most existing indoor localization methods lead to poor accuracy and many of them are not suitable for large space environments. In this article, we propose a novel approach for indoor localization and navigation. In our approach, the expensive training is avoided by utilizing the concept of pre-scheduled path and automatically mapping the WiFi fingerprints to it. For online tracing, we utilize historical sensor data to delineate users’ trajectory and calculate the similarity to all possible paths on the map, then the system chooses the most similar one as the result. The proposed work is evaluated and compared with previous methods. The results show that our approach improves accuracy by 80%.
Management of intermittent claudication with pentoxifylline: meta-analysis of randomized controlled trials.

OBJECTIVE To evaluate the efficacy of pentoxifylline therapy in improving the walking capacity of patients with moderate intermittent claudication. DATA SOURCES A search of MEDLINE for trials published between 1976 and 1994 inclusive, and a bibliographic review of all articles retrieved. STUDY SELECTION Randomized, placebo-controlled, double-blind clinical trials were selected that evaluated the pain-free walking distance (the distanced walked on a treadmill before the onset of calf pain) and the absolute claudication distance (the maximum distance walked on a treadmill) among patients with moderate intermittent claudication. Twelve study groups in 11 trials were included in the analysis. DATA EXTRACTION In addition to information regarding the trial design, patient characteristics, dosages and treatment periods, the means and standard deviations were collected for both the pain-free walking and absolute claudication distances. Trial quality was also assessed. DATA SYNTHESIS Overall, there was a statistically significant improvement in the pain-free walking distance after pentoxifylline therapy (weighted mean difference 29.4 m [95% confidence interval (CI) 13.0 to 45.9 m]); this finding was based on a total sample of 612 patients (308 in the treatment groups and 304 in the control groups). A significant improvement was also noted in the absolute claudication distance (weighted mean difference 48.4 m [95% CI 18.3 to 78.6 m]); this was based on a total sample of 511 patients (258 in the treatment group and 253 in the control group). In a sensitivity analysis of the pain-free walking distance, significant treatment effects and no statistically significant heterogeneity were found when only trials were included that were "medically eligible" (involved patients with stage II disease and a pain-free walking distance of 50 to 200 m). In a similar sensitivity analysis of the absolute claudication distance, the two conditions resulting in a significant treatment effect and no significant heterogeneity were the inclusion of "medically eligible" trials and those with a shorter treatment duration (13 weeks or less). CONCLUSION Pentoxifylline therapy may be efficacious in improving the walking capacity of patients with moderate intermittent claudication. However, properly conducted clinical trials are required to provide a true estimate of the benefit.

Use of horizontal subsurface flow constructed wetlands to treat reverse osmosis concentrate of rolling wastewater

ABSTRACT According to the characteristics of the reverse osmosis concentrate (ROC) generated from iron and steel company, we used three sets of parallel horizontal subsurface flow (HSF) constructed wetlands (CWs) with different plants and substrate layouts to treat the high-salinity wastewater. The plant growth and removal efficiencies under saline condition were evaluated. The evaluation was based entirely on routinely collected water quality data and the physical and chemical characteristics of the plants (Phragmites australis, Typha latifolia, Iris wilsonii, and Scirpus planiculmis). The principal parameters of concern in the effluent were chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP). The results showed that the CWs were able to remove COD, TN, and TP from ROC. S. planiculmis was not suitable for the treatment of high-saline wastewater. The sequence of metals accumulated in CW plants was K>Ca>Na>Mg>Zn>Cu. More than 70% of metals were accumulated in the aboveground of P. australis. The CW filled with gravel and manganese ore and planted with P. australis and T. latifolia had the best performance of pollutant removal, with average removal of 49.96%, 39.45%, and 72.01% for COD, TN, and TP, respectively. The effluent water quality met the regulation in China. These results suggested that HSF CW planted with P. australis and T. latifolia can be applied for ROC pollutants removal.
Preiskonvergenz in der erweiterten Europäischen Union

Die fortschreitende europaische Integration fuhrt tendenziell zu einer Annaherung der Preise von Gutern und Dienstleistungen. Mit der Erweiterung der EU hat sich dieser Prozess etwas beschleunigt. Der Beitritt der mittel- und osteuropaischen Lander beeinflusst die Preiskonvergenz auf zweierlei Weise. Zum einen erhoht sich in der EU insgesamt der Druck auf die Preise aufgrund des intensiveren Wettbewerbs. Zum anderen steigt das bisher noch relativ niedrige Preisniveau in den neuen Mitgliedslandern im Zuge des wirtschaftlichen Aufholprozesses.
