Heuristic-Based Approaches for CP-Nets in Negotiation

CP-Nets have proven to be an effective representation for ca pturing preferences. However, their use in multiagent negotiat i n is not straightforward. The main reason for this is that CP-Net s capture partial ordering of preferences, whereas negotiating agents are required to compare any two outcomes based on the request and offers. This makes it necessary for agents to generate total orders from their CP-Nets. We have previously proposed a heuristic to generate total orders from a given CP-Net. This paper propos es another heuristic based on Borda count, applies it in negotiat i n, and compares its performance with the previous heuristic.
Developing and Validating an Observational Learning Model of Computer Software Training and Skill Acquisition

Computer skills are key to organizational performance, and past research indicates that behavior modeling is a highly effective form of computer skill training. The present research develops and tests a new theoretical model of the underlying observational learning processes by which modeling-based training interventions influence computer task performance. Observational learning processes are represented as a second-order construct with four dimensions (attention, retention, production, and motivation). New measures for these dimensions were developed and shown to have strong psychometric properties. The proposed model controls for two pretraining individual differences (motivation to learn and self-efficacy) and specifies the relationships among three training outcomes (declarative knowledge, post-training self-efficacy, and task performance). The model was tested using PLS on data from an experiment (N = 95) on computer spreadsheet training. As hypothesized, observational learning processes significantly influenced training outcomes. A representative modeling-based training intervention (retention enhancement) significantly improved task performance through its specific effects on the retention processes dimension of observational learning. The new model provides a more complete theoretical account of the mechanisms by which modeling-based interventions affect training outcomes, which should enable future research to systematically evaluate the effectiveness of a wide range of modeling-based training interventions. Further, the new instruments can be used by practitioners to refine ongoing training programs.

Radiographic and metabolic response rates following image-guided stereotactic radiotherapy for lung tumors.

PURPOSE
To evaluate radiographic and metabolic response after stereotactic body radiotherapy (SBRT) for early lung tumors.


MATERIALS AND METHODS
Thirty-nine tumors were treated prospectively with SBRT (dose=48-60 Gy, 4-5 Fx). Thirty-six cases were primary NSCLC (T1N0=67%; T2N0=25%); three cases were solitary metastases. Patients were followed using CT and PET at 6, 16, and 52 weeks post-SBRT, with CT follow-up thereafter. RECIST and EORTC criteria were used to evaluate CT and PET responses.


RESULTS
At median follow-up of 9 months (0.4-26), RECIST complete response (CR), partial response (PR), and stable disease (SD) rates were 3%, 43%, 54% at 6 weeks; 15%, 38%, 46% at 16 weeks; 27%, 64%, 9% at 52 weeks. Mean baseline tumor volume was reduced by 46%, 70%, 87%, and 96%, respectively at 6, 16, 52, and 72 weeks. Mean baseline maximum standardized uptake value (SUV) was 8.3 (1.1-20.3) and reduced to 3.4, 3.0, and 3.7 at 6, 16, and 52 weeks after SBRT. EORTC metabolic CR/PR, SD, and progressive disease rates were 67%, 22%, 11% at 6 weeks; 86%, 10%, 3% at 16 weeks; 95%, 5%, 0% at 52 weeks.


CONCLUSIONS
SBRT yields excellent RECIST and EORTC based response. Metabolic response is rapid however radiographic response occurs even after 1-year post treatment.
Integrated medical care for patients with serious psychiatric illness: a randomized trial.

BACKGROUND
This randomized trial evaluated an integrated model of primary medical care for a cohort of patients with serious mental disorders.


METHODS
A total of 120 individuals enrolled in a Veterans Affairs (VA) mental health clinic were randomized to receive primary medical care through an integrated care initiative located in the mental health clinic (n = 59) or through the VA general medicine clinic (n = 61). Veterans who obtained care in the integrated care clinic received on-site primary care and case management that emphasized preventive medical care, patient education, and close collaboration with mental health providers to improve access to and continuity of care. Analyses compared health process (use of medical services, quality of care, and satisfaction) and outcomes (health and mental health status and costs) between the groups in the year after randomization.


RESULTS
Patients treated in the integrated care clinic were significantly more likely to have made a primary care visit and had a greater mean number of primary care visits than those in the usual care group. They were more likely to have received 15 of the 17 preventive measures outlined in clinical practice guidelines. Patients assigned to the integrated care clinic had a significantly greater improvement in health as measured by the physical component summary score of the 36-Item Short-Form Health Survey than patients assigned to the general medicine clinic (4.7 points vs -0.3 points, P<.001). There were no significant differences between the 2 groups in any of the measures of mental health symptoms or in total health care costs.


CONCLUSION
On-site, integrated primary care was associated with improved quality and outcomes of medical care.
Comparison of some well-known PID tuning formulas

Criteria based on disturbance rejection and system robustness are proposed to assess the performance of PID controllers. A simple robustness measure is defined and the integral gains of the PID controllers are shown to be a good measure for disturbance rejection. An analysis of some well-known PID tuning formulas reveals that the robustness measure should lie between 3 and 5 to have a good compromise between performance and robustness. © 2006 Published by Elsevier Ltd.
Evaluation of the hamstring muscle complex following acute injury

To evaluate the imaging findings following acute hamstring injury. We retrospectively reviewed the imaging findings of hamstring muscle complex (HMC) strain in 170 patients referred to our institution over a 3-year period. A total of 179 injuries to the HMC were demonstrated in 170 patients (154 male, 16 female, mean age 28.2 years). The mean duration of symptoms was 4.7 days (range 1–10 days). MR imaging was performed in 97 cases and sonography in 102 cases (both modalities were performed in 20 examinations). Attention was directed to the frequency of muscle involvement, the location of the injury within the muscle-tendon unit, the extent of the injury and discriminating avulsion from muscle injury. Twenty-one patients had proximal tendon injury, with sixteen avulsions and five partial tears. Sixteen of these patients had surgical confirmation of hamstring avulsion from the ischial tuberosity (14 conjoint, 2 biceps femoris alone) and all were reliably diagnosed with MR imaging (16/16), but less so with sonography (7/12). Four distal tendon avulsions were also observed (three semitendinosus, one biceps femoris). With respect to muscle injury, the biceps femoris was most commonly injured (124/154). Semimembranosus was an uncommon muscle injury (21/154) and semitendinosus rare (9/154). Imaging can discriminate a hamstring tendon avulsion from musculotendinous strain and helps identify which patients necessitate surgical management as opposed to conservative treatment.
Clinical and microbiological features of vulvovaginitis in Mexican girls

Study Objective: To determine the prevalence of vulvovaginitis, predisposing factors, microbial etiology and therapy in patients treated at the Hospital del Niño DIF, Pachuca, Hidalgo, Mexico. Design. This was an observational and descriptive study from 2006 to 2009. Setting: Hospital del Niño DIF, Pachuca, Hidalgo, Mexico. Participants. Patients from 0 to 16 years, with vulvovaginitis and/or vaginal discharge were included. Interventions: None. Main Outcome Measures: Demographic data, etiology, clinical features, risk factors and therapy were analyzed. Results: Four hundred twenty seven patients with diagnosis of vulvovaginitis were included. The average prevalence to 4 years in the study period was 0.19%. The age group most affected was schoolchildren (225 cases: 52.69%). The main signs and symptoms presented were leucorrhea (99.3%), vaginal hyperemia (32.6%), vulvar itching (32.1%) and erythema (28.8%). Identified risk factors were poor hygiene (15.7%), urinary tract infection (14.7%), intestinal parasites (5.6%) and obesity or overweight (3.3%). The main microorganisms found in vaginal cultures were enterobacteriaceae (Escherichia coli, Klebsiella and Enterococcus faecalis), Staphylococcus spp, and Gardnerella vaginalis. Several inconsistent were found in the drug prescription of the patients. Conclusion: Vulvovaginitis prevalence in Mexican girls is low and this was caused mainly by opportunist microorganisms. The initial treatment of vulvovaginitis must include hygienic measure and an antimicrobial according to the clinical features and microorganism found.
Interpreting the Object Constraint Language

The Object Constraint Language (OCL), which forms part of the UML 1.1. set of modelling notations is a precise, textual language for expressing constraints that cannot be shown in the standard diagrammatic notation used in UML. A semantics for OCL lays the foundation for building CASE tools that support integrity checking of whole UML models, not just the component expressed using OCL. This paper provides a semantics for OCL, at the same time providing a semantics for classes, associations, attributes and states.
Development of fungal cell factories for the production of secondary metabolites: Linking genomics and metabolism

The genomic era has revolutionized research on secondary metabolites and bioinformatics methods have in recent years revived the antibiotic discovery process after decades with only few new active molecules being identified. New computational tools are driven by genomics and metabolomics analysis, and enables rapid identification of novel secondary metabolites. To translate this increased discovery rate into industrial exploitation, it is necessary to integrate secondary metabolite pathways in the metabolic engineering process. In this review, we will describe the novel advances in discovery of secondary metabolites produced by filamentous fungi, highlight the utilization of genome-scale metabolic models (GEMs) in the design of fungal cell factories for the production of secondary metabolites and review strategies for optimizing secondary metabolite production through the construction of high yielding platform cell factories.

The performance tradeoffs of the different modulation schemes and scanning antenna types used by these radar sensors are discussed. The test requirements of these millimeter wave radar sensors during production, installation on a vehicle, and during after-market service are also discussed. Different test methods used for characterizing and aligning these radar sensors are presented.
A New Scaling and Squaring Algorithm for the Matrix Exponential

The scaling and squaring method for the matrix exponential is based on the approximation eA ≈ (rm(2A)) s , where rm(x) is the [m/m] Padé approximant to ex and the integers m and s are to be chosen. Several authors have identified a weakness of existing scaling and squaring algorithms termed overscaling, in which a value of s much larger than necessary is chosen, causing a loss of accuracy in floating point arithmetic. Building on the scaling and squaring algorithm of Higham [SIAM J. Matrix Anal. Appl., 26(4):1179–1193, 2005], which is used by MATLAB’s expm, we derive a new algorithm that alleviates the overscaling problem. Two key ideas are employed. The first, specific to triangular matrices, is to compute the diagonal elements in the squaring phase as exponentials instead of from powers of rm. The second idea is to base the backward error analysis that underlies the algorithm on members of the sequence {‖Ak‖1/k} instead of ‖A‖, since for non-normal matrices it is possible that ‖Ak‖1/k is much smaller than ‖A‖, and indeed this is likely when overscaling occurs in existing algorithms. The terms ‖Ak‖1/k are estimated without computing powers of A by using a matrix 1-norm estimator in conjunction with a bound of the form ‖Ak‖1/k ≤ max ( ‖Ap‖1/p, ‖Aq‖1/q ) that holds for certain fixed p and q less than k. The improvements to the truncation error bounds have to be balanced by the potential for a large ‖A‖ to cause inaccurate evaluation of rm in floating point arithmetic. We employ rigorous error bounds along with some heuristics to ensure that rounding errors are kept under control. Our numerical experiments show that the new algorithm generally provides accuracy at least as good as the existing algorithm of Higham at no higher cost, while for matrices that are triangular or cause overscaling it usually yields significant improvements in accuracy, cost, or both.
Storage methods for extending shelf life of fresh, edible bamboo shoots [Bambusa oldhamii (Munro)]

Fresh bamboo [Bambusa oldhamii (Munro)] shoots were harvested, and stored in the open or packaged in a range of materials at different temperatures (1, 2, 8, 11, 20, 25°C) to determine their shelf life under various storage conditions. Shelflife could be extended by primarily reducing storage temperature and secondarily packaging bamboo shoots. Under traditional storage at ambient temperature (20–25°C) without packaging, high transpirational weight loss (22.690.5% of initial fresh weight after 6 days storage duration) limited shelf life of bamboo shoots to 1 day. When water loss was reduced to 2.290.1% of initial fresh weight by enclosing shoots in low-density polyethylene (LDPE) film, shelf life was extended to 6 days. Under those conditions, respiration (2.9790.22 mmol CO2 kg h) accounted for a larger percentage of total weight loss (35% after 6 days) and a Q10 of 2.3 for respiration between 20 and 2°C stressed the need to quickly cool bamboo shoots after harvest and reduce storage temperatures. At temperatures above 1–2°C (i.e. 8°C), discoloration and fungal growth reduced shelf life of bamboo shoots to not more than 10 days. Microbial decay appeared to be the primary cause for this deterioration in quality since bacterial, fungal and coliform microorganisms were present on external surfaces and internal tissues of shoots. At 1–2°C, respiration (about 0.7 mmol CO2 kg −1 h) was low and, therefore, transpiration accounted for up to 94% of total weight loss. Shelf life at these low storage temperatures was affected by weight loss and decline in visual packaging quality. Weight loss from packages was greater in the more permeable materials, e.g. the shelf life of shoots in macro-perforated LDPE bags (8.9% area perforated) was reduced to 17 days. In contrast, accumulation of condensate in low-permeable materials (LDPE bags and particularly heat-sealed PVC film) reduced shelf life to 21 and 14 days due to loss of visual packaging quality. The most suitable packaging materials were thin, micro-perforated (45 mm, 0.01% perforation) LDPE bags and non-perforated LDPE film (10.5 mm thick). This reduced total weight loss of bamboo shoots to about 5% after 28 days, minimized condensation within packages and extended shelf life to, and probably beyond 28 days. © 2000 Elsevier Science B.V.

Smart Power Grid Synchronization With Fault Tolerant Nonlinear Estimation

Effective real-time state estimation is essential for smart grid synchronization, as electricity demand continues to grow, and renewable energy resources increase their penetration into the grid. In order to provide a more reliable state estimation technique to address the problem of bad data in the PMU-based power synchronization, this paper presents a novel nonlinear estimation framework to dynamically track frequency, voltage magnitudes and phase angles. Instead of directly analyzing in abc coordinate frame, symmetrical component transformation is employed to separate the positive, negative, and zero sequence networks. Then, Clarke's transformation is used to transform the sequence networks into the αβ stationary coordinate frame, which leads to system model formulation. A novel fault tolerant extended Kalman filter based real-time estimation framework is proposed for smart grid synchronization with noisy bad data measurements. Computer simulation studies have demonstrated that the proposed fault tolerant extended Kalman filter (FTEKF) provides more accurate voltage synchronization results than the extended Kalman filter (EKF). The proposed approach has been implemented with dSPACE DS1103 and National Instruments CompactRIO hardware platforms. Computer simulation and hardware instrumentation results have shown the potential applications of FTEKF in smart grid synchronization.
Natural language processing

A procedure is described whereby a computer can determine whether two fingerpring impressions were made by the same finger. The procedure used the X and Y coordinates and the individual directions of the minutiae (ridge endings and bifurcations). The identity of two impressions is established by computing the density of clusters of points in AX and AY space where AX and AY are the differences in coordinates that are found in going from one of the fingerpring impressions to the other. Single fingerpring classification is discussed and experimental results using machine-read minutiae data are given. References: J. H.

Neuropathy after sodium tetradecyl sulfate sclerotherapy of venous malformations in children.

PURPOSE
To estimate the risk of nerve injuries and assess outcomes after sodium tetradecyl sulfate (STS) sclerotherapy of venous malformations (VMs) in children.


MATERIALS AND METHODS
Sclerotherapy is the treatment of choice for most VMs, but all sclerotherapy agents are associated with the risk of complications. Neuropathy is considered a rare but potentially serious complication of venous sclerotherapy. The institutional review board waived ethical approval for this retrospective review, in which 647 sclerotherapy procedures were performed in 204 patients (104 female and 100 male patients; mean age, 9 years 6 months [range, 6 months to 17 years 11 months]) as treatment for symptomatic VMs. Technical and clinical success of the treatment was evaluated. Complications were reviewed with a particular focus on nerve injury. Informed consent, specifying the risk of neuropathy, as well as pain, swelling, infection, risks of anesthesia, skin injury, nonresolution or worsening of symptoms, and possible need for further or multiple procedures, was obtained for all patients. Standard sclerotherapy techniques were used. Technical details of all procedures were recorded prospectively. Follow-up included immediate postprocedural assessment and outpatient clinic review. All nerve injuries were recorded. Patients were monitored and treated according to clinical need. Confidence intervals were calculated by using the Wilson method, without correction for continuity.


RESULTS
Treatment was technically successful in 197 of 204 patients (96.6%), and clinical success was achieved in 174 of 204 (85.3%). Thirty-seven of the 647 procedures (5.7%) resulted in a complication, including 11 cases of excessive swelling, nine cases of skin injury, two patients with infection, and two with pain. Motor and/or sensory nerve injuries occurred after seven procedures (1.1%). Five of the seven children had undergone at least one previous sclerotherapy procedure. Neuropathy resolved spontaneously in four patients and partially recovered in three, of whom two underwent surgery. Surgery included debridement of necrotic tissue, carpal tunnel decompression, and external neurolysis.


CONCLUSION
Nerve injury is an unusual but not rare complication of STS sclerotherapy. A degree of recovery, which may be complete, can be expected in most patients.
