Automatic Recognition Algorithm of Quick Response Code Based on Embedded System

The automatic recognition algorithm of quick response code is discussed in this paper. An image processing system based on embedded system is described to be able to binarization, location, segment, and decoding the QR code. In order to adapting various sizes, various gray-level values, and under various lighting conditions of real bar code image, a high-speed, high-accuracy binarization method is developed, which can locate the finder pattern accurately and integrate the local thresholding method with global thresholding. Experiments have shown that over 99% barcode can be optimally recognized with the proposed algorithm. It can achieve higher recognition rate of high density bar code, and is applicable to real world scene image
Dyadic integration of the performance management process : A delivery service case study

Purpose: The purpose is to explore how to integrate the performance management (PM) process of delivery service in customer/supplier dyads. Methodology/approach: The paper is based on a multiple case study of six customer/supplier dyads of manufacturing companies. Findings: The analysis focuses on describing and comparing the activities of the performance management process. Most activities show low levels of integration in the dyads studied. Defining metrics and target setting are considered most important to integrate. Lack of common metrics definitions and ERP deficiencies were important obstacles for integration. Research issues related to four areas of supply chain performance management are discussed. Research limitations/implications: The study ends with a number of suggestions for further research on the PM process in supply chains. Proceeding into these studies is necessary for increasing knowledge about PM. Practical implications: The paper reveals practical problems and outlines practical issues in integrating and handling the PM process in dyads, especially when measuring delivery service using the on-time delivery metric. It also presents a model for describing and integrating the performance management process and its activities. Originality/value of the paper: Practical implications and generation of multiple issues for further research applying a dyadic approach in supply chain performance management, a research approach that is quite uncommon.
CRONOS: the cross-reference navigation server

UNLABELLED
Cross-mapping of gene and protein identifiers between different databases is a tedious and time-consuming task. To overcome this, we developed CRONOS, a cross-reference server that contains entries from five mammalian organisms presented by major gene and protein information resources. Sequence similarity analysis of the mapped entries shows that the cross-references are highly accurate. In total, up to 18 different identifier types can be used for identification of cross-references. The quality of the mapping could be improved substantially by exclusion of ambiguous gene and protein names which were manually validated. Organism-specific lists of ambiguous terms, which are valuable for a variety of bioinformatics applications like text mining are available for download.

Development and validation of a highly sensitive LC-ESI-MS/MS method for the determination of Orteronel® (TAK-700) in rat plasma: application to a pharmacokinetic study.

BACKGROUND
A highly sensitive, specific and high-throughput LC-ESI-MS/MS method in the positive mode has been developed and validated for the quantitation of Orteronel® (TAK-700) in rat plasma using YM-55208 as an internal standard.


RESULTS
The assay procedure involves extraction of Orteronel and internal standard from rat plasma with liquid-liquid extraction method. Chromatographic separation was achieved using an isocratic mobile phase at a flow rate of 0.6 ml/min on an Atlantis dC18 column with a total run time of 2.5 min. The MS/MS ion transitions monitored were m/z 308.4→95.0 for Orteronel and m/z 262.3→194.2 for IS. Method validation was performed as per US FDA guidelines. The LLOQ achieved was 0.42 ng/ml and the linearity range extended from 0.42 to 814 ng/ml.


CONCLUSION
The results met the acceptance criteria. The validated method was successfully applied to characterize the pharmacokinetic parameters of Orteronel in rat plasma.
EVOLUTION OF PARAMETERS OF NONLINEAR POSITION CONTROL FOR DYNAMIC MODEL OF MOBILE ROBOT WITH FRICTION

In this paper, we propose two level control system for a mobile robot. The first level subsystem deals with the control of the linear and angular volocities using a multivariable PI controller described with a full matrix. The position control of the mobile robot represents the second level control, which is nonlinear. The nonlinear control design is implemented by a modified backstepping algorithm whose parameters are adjusted by a genetic algorithm, which is a robust nonlinear optimization method. The performance of the proposed system is investigated using a dynamic model of a nonholonomic mobile robot with friction. We present a new dynamic model in which the angular velocities of wheels are main variables. Simulation results show the good quality of position tracking capabilities a mobile robot with the various viscous friction torques. Copyright © 2005 IFAC.
Tachikawa project for prevention of posttraumatic stress disorder with polyunsaturated fatty acid (TPOP): study protocol for a randomized controlled trial

BACKGROUND
Preclinical and clinical studies suggest that supplementation with omega-3 fatty acids after trauma might reduce subsequent posttraumatic stress disorder (PTSD). To date, we have shown in an open trial that PTSD symptoms in critically injured patients can be reduced by taking omega-3 fatty acids, hypothesized to stimulate hippocampal neurogenesis. The primary aim of the present randomized controlled trial is to examine the efficacy of omega-3 fatty acid supplementation in the secondary prevention of PTSD following accidental injury, as compared with placebo. This paper describes the rationale and protocol of this trial.


METHODS/DESIGN
The Tachikawa Project for Prevention of Posttraumatic Stress Disorder with Polyunsaturated Fatty Acid (TPOP) is a double-blinded, parallel group, randomized controlled trial to assess whether omega-3 fatty acid supplementation can prevent PTSD symptoms among accident-injured patients consecutively admitted to an intensive care unit. We plan to recruit accident-injured patients and follow them prospectively for 12 weeks. Enrolled patients will be randomized to either the omega-3 fatty acid supplement group (1,470 mg docosahexaenoic acid and 147 mg eicosapentaenoic acid daily) or placebo group. Primary outcome is score on the Clinician-Administered PTSD Scale (CAPS). We will need to randomize 140 injured patients to have 90% power to detect a 10-point difference in mean CAPS scores with omega-3 fatty acid supplementation compared with placebo. Secondary measures are diagnosis of PTSD and major depressive disorder, depressive symptoms, physiologic response in the experiment using script-driven imagery and acoustic stimulation, serum brain-derived neurotrophic factor, health-related quality of life, resilience, and aggression. Analyses will be by intent to treat. The trial was initiated on December 13 2008, with 104 subjects randomized by November 30 2012.


DISCUSSION
This study promises to be the first trial to provide a novel prevention strategy for PTSD among traumatized people.

Effect of Noninvasive Ventilation on Tracheal Reintubation Among Patients With Hypoxemic Respiratory Failure Following Abdominal Surgery: A Randomized Clinical Trial.

IMPORTANCE
It has not been established whether noninvasive ventilation (NIV) reduces the need for invasive mechanical ventilation in patients who develop hypoxemic acute respiratory failure after abdominal surgery.


OBJECTIVE
To evaluate whether noninvasive ventilation improves outcomes among patients developing hypoxemic acute respiratory failure after abdominal surgery.


DESIGN, SETTING, AND PARTICIPANTS
Multicenter, randomized, parallel-group clinical trial conducted between May 2013 and September 2014 in 20 French intensive care units among 293 patients who had undergone abdominal surgery and developed hypoxemic respiratory failure (partial oxygen pressure <60 mm Hg or oxygen saturation [SpO2] ≤90% when breathing room air or <80 mm Hg when breathing 15 L/min of oxygen, plus either [1] a respiratory rate above 30/min or [2] clinical signs suggestive of intense respiratory muscle work and/or labored breathing) if it occurred within 7 days after surgical procedure.


INTERVENTIONS
Patients were randomly assigned to receive standard oxygen therapy (up to 15 L/min to maintain SpO2 of 94% or higher) (n = 145) or NIV delivered via facial mask (inspiratory pressure support level, 5-15 cm H2O; positive end-expiratory pressure, 5-10 cm H2O; fraction of inspired oxygen titrated to maintain SpO2 ≥94%) (n = 148).


MAIN OUTCOMES AND MEASURES
The primary outcome was tracheal reintubation for any cause within 7 days of randomization. Secondary outcomes were gas exchange, invasive ventilation-free days at day 30, health care-associated infections, and 90-day mortality.


RESULTS
Among the 293 patients (mean age, 63.4 [SD, 13.8] years; n=224 men) included in the intention-to-treat analysis, reintubation occurred in 49 of 148 (33.1%) in the NIV group and in 66 of 145 (45.5%) in the standard oxygen therapy group within+ 7 days after randomization (absolute difference, -12.4%; 95% CI, -23.5% to -1.3%; P = .03). Noninvasive ventilation was associated with significantly more invasive ventilation-free days compared with standard oxygen therapy (25.4 vs 23.2 days; absolute difference, -2.2 days; 95% CI, -0.1 to 4.6 days; P = .04), while fewer patients developed health care-associated infections (43/137 [31.4%] vs 63/128 [49.2%]; absolute difference, -17.8%; 95% CI, -30.2% to -5.4%; P = .003). At 90 days, 22 of 148 patients (14.9%) in the NIV group and 31 of 144 (21.5%) in the standard oxygen therapy group had died (absolute difference, -6.5%; 95% CI, -16.0% to 3.0%; P = .15). There were no significant differences in gas exchange.


CONCLUSIONS AND RELEVANCE
Among patients with hypoxemic respiratory failure following abdominal surgery, use of NIV compared with standard oxygen therapy reduced the risk of tracheal reintubation within 7 days. These findings support use of NIV in this setting.

Data de desmame e desempenho reprodutivo de vacas de corte

The experiment was run at the Agronomic Experimental Station of the Federal University of Rio Grande do Sul, located in the district of Eldorado do Sul, Brazil. The objective of the study was to evaluate the effect of the date of early (01/05/99) or conventional (03/26/99) weaning on the reproductive performance of multiparous beef cows during two mating seasons, 98/99, and the subsequent, 99/00. Fifty cows had their calves weaned with an average age of 91 days old and a minimum liveweight of 70 kg (early weaning = EW), and 43 cows had calves weaned with an average age of 170 days old and mean liveweight of 131.2 kg (conventional weaning = CW). The mating periods were from 12/01/98 to 02/26/99 and from 12/06/99 to 02/28/00. Cows of EW had higher daily liveweight gains and better body condition (BC) than CW during the first breeding season (0.828 kg x 0.549 kg; 2.4 x 2.0; P<0.05). The pregnancy rate in 1999 was 40.0% x 11.1% and in 2000 it was 51.4% x 20.0% for EW and CW, respectively. There was no difference in the calving intervals. The pregnancy rate at first mating was lower than the expected, probably due to the low BC at beginning of the mating season and to the low recovery during the mating period. The EW improved cows BC during the first mating, making possible significantly better reproductive rates than the CW.

Comparative outcomes of open-wedge high tibial osteotomy with platelet-rich plasma alone or in combination with mesenchymal stem cell treatment: a prospective study.

PURPOSE
This study compared the clinical results and second-look arthroscopic findings of patients undergoing open-wedge high tibial osteotomy (HTO) for varus deformity, with or without mesenchymal stem cell (MSC) therapy.


METHODS
This prospective, comparative observational study was designed to evaluate the effectiveness of MSC therapy. The patients were divided into 2 groups: HTO with platelet-rich plasma (PRP) injection only (n = 23) or HTO in conjunction with MSC therapy and PRP injection (n = 21). Prospective evaluations of both groups were performed using the Lysholm score, Knee Injury and Osteoarthritis Outcome Score (KOOS), and a visual analog scale (VAS) score for pain. Second-look arthroscopy was carried out in all patients at the time of metal removal.


RESULTS
The patients in the MSC-PRP group showed significantly greater improvements in the KOOS subscales for pain (PRP only, 74.0 ± 5.7; MSC-PRP, 81.2 ± 6.9; P < .001) and symptoms (PRP only, 75.4 ± 8.5; MSC-PRP, 82.8 ± 7.2; P = .006) relative to the PRP-only group. Although the mean Lysholm score was similarly improved in both groups (PRP only, 80.6 ± 13.5; MSC-PRP, 84.7 ± 16.2; P = .357), the MSC-PRP group showed a significantly greater improvement in the VAS pain score (PRP only, 16.2 ± 4.6; MSC-PRP, 10.2 ± 5.7; P < .001). There were no differences in the preoperative (PRP only, varus 2.8° ± 1.7°; MSC-PRP, varus 3.4° ± 3.0°; P = .719) and postoperative (PRP only, valgus 9.8° ± 2.4°; MSC-PRP, valgus 8.7° ± 2.3°; P = .678) femorotibial angles or weight-bearing lines between the groups. Arthroscopic evaluation, at plate removal, showed that partial or even fibrocartilage coverage was achieved in 50% of the MSC-PRP group patients but in only 10% of the patients in the PRP-only group (P < .001).


CONCLUSIONS
MSC therapy, in conjunction with HTO, mildly improved cartilage healing and showed good clinical results in some KOOS subscores and the VAS pain score compared with PRP only.

Encapsulating Plurality

This paper discusses the Gaggle, a mechanism for grouping and naming objects in a distributed system. Using Gaggles, client objects can access distributed replicated services without regard for the number of objects that provide the service. In this way they encapsulate plurality. Rather than imposing a particular design philosophy, Gaggles allow implementors of replicated distributed services full freedom to structure those services as they see fit. A Gaggle behaves very much like an object: it can be named in the same way as an object, and can be used as the invokee of an invocation. However, Gaggles can be used to represent individual objects, several ordinary objects, or even several other Gaggles, so they serve to encapsulate plurality. If a Gaggle is used as an invokee, one of the objects that it represents is chosen to be the receiver.
Nurse and physician perspectives on patients with cancer having online access to their laboratory results.

PURPOSE/OBJECTIVES
To compare the perspectives of oncology nurses and physicians regarding online access to laboratory results for patients with cancer pre- and postimplementation, and to evaluate the impact on workload.


DESIGN
Pre- and postimplementation surveys distributed to nurses and physicians. In addition, a nursing workload study was conducted to measure the number of phone calls received from patients regarding laboratory results.


SETTING
The outpatient department of a comprehensive cancer center in a large, urban setting in the northeastern United States with more than 500,000 patient visits each year.


SAMPLE
460 outpatient nurses and 349 attending physicians were surveyed; 10 of those nurses were invited to participate in the nursing workload study, as well.


METHODS
A survey was sent to nurses and physicians one month prior to implementation and then repeated six months postimplementation. A nursing workload study was conducted for 16 weeks beginning one month prior to implementation and completed three months postimplementation.


MAIN RESEARCH VARIABLES
Nurse and physician perspectives; nursing workload.


FINDINGS
Nurses demonstrated greater support than physicians with regard to patient access, their level of comfort with the patient access, and patients' ability to interpret results. Statistical significance was identified in all three questions (p<0.05). Perspectives on workload did not differ by role; nurses and physicians anticipated an increase in workload prior to implementation, but reported that workload decreased or stayed the same postimplementation (p<0.005). The nursing workload study supported that finding because no change was observed in the average number of phone calls per day during the implementation period.


CONCLUSIONS
Oncology nurses and physicians have different perspectives on providing patients with cancer with online access to laboratory results. Concerns about increasing workload were not substantiated in the current study.


IMPLICATIONS FOR NURSING
Providing patients with online access to their laboratory results is a growing trend. Understanding the perspectives of oncology nurses can inform future directions for increasing health-record transparency for patients with cancer. Future research may explore the impact on the nurse-patient relationship.
Gestational sac volume measured by three-dimensional ultrasound at 11 to 13 + 6 weeks of gestation: relation to chromosomal defects.

OBJECTIVE
To determine the potential value of measuring the gestational sac volume (GSV) at 11 to 13 + 6 weeks of gestation in screening for chromosomal defects.


METHODS
The GSV was measured using three-dimensional (3D) ultrasound in 500 consecutive singleton pregnancies immediately before chorionic villus sampling (CVS) for fetal karyotyping at 11 to 13 + 6 (median 12) weeks of gestation.


RESULTS
The fetal karyotype was normal in 417 pregnancies and abnormal in 83. In the chromosomally normal group, the mean GSV increased significantly with gestational age from a mean of 69 mL at 11 weeks to 144 mL at 13 + 6 weeks (the standard deviation was 27 mL). In the chromosomally abnormal group, the mean GSV for gestational age was not significantly different from normal in fetuses with trisomy 21, trisomy 18 and Turner syndrome, but it was smaller in those with triploidy and trisomy 13. However, the mean GSV for crown-rump length (CRL) was significantly larger in trisomy 18, smaller in triploidy and trisomy 13, and not different from normal in trisomy 21 and Turner syndrome. The mean CRL for gestational age was significantly smaller than normal in trisomy 18, triploidy and trisomy 13.


CONCLUSIONS
The measurement of the GSV at 11 to 13 + 6 weeks of gestation is unlikely to provide useful prediction of the major chromosomal defects. In trisomy 13 and triploidy, the small GSV may be due to early onset fetal growth restriction and reduced amniotic fluid volume. In trisomy 18, the increase in GSV is probably due to the presence of associated fetal abnormalities that interfere with fetal swallowing.
PSO trained ANN-based differential protection scheme for power transformers

In this paper, a novel scheme is proposed which monitors and discriminates the different operating conditions (normal, magnetizing inrush current, over excitation of the core, internal faults and CT saturation due to external faults) of power transformers. The Particle Swarm Optimization (PSO) technique is used to train the multi-layered feed forward neural networks to discriminate the different operating conditions. The proposed scheme has been realized through two different Artificial Neural Network (ANN) architectures. One is used as an internal fault detector and the other one detects and discriminates the other operating conditions like normal, inrush, over excitation, and CT saturation due to external faults. These two ANNs were trained using Back Propagation Neural Network Algorithm (BPN) and PSO technique and the simulated results are compared. Simulations are performed for the practical power transformer ratings obtained from Tamilnadu Electricity Board (TNEB), India. Comparing the simulated results of the above two cases, training the neural network by PSO technique gives more accurate (in terms of sum square error) and also faster (in terms of number of iterations and simulation time) results than BPN. The PSO trained ANN-based differential protection scheme provides faster, accurate, more secured and dependable results for power transformers. r 2007 Elsevier B.V. All rights reserved.
EGFR expression is associated with decreased benefit from trastuzumab in the NCCTG N9831 (Alliance) trial

Background:Epidermal growth factor receptor (EGFR) has been hypothesised to modulate the effectiveness of anti-HER2 therapy. We used a standardised, quantitative immunofluorescence assay and a novel EGFR antibody to evaluate the correlation between EGFR expression and clinical outcome in the North Central Cancer Treatment Group (NCCTG) N9831 trial.Methods:Tissue microarrays were constructed that allowed analysis of 1365 patients randomly assigned to receive chemotherapy alone (Arm A), sequential trastuzumab after chemotherapy (Arm B) and chemotherapy with concurrent trastuzumab (Arm C). Measurement of EGFR was performed using the EGFR antibody, D38B1, on the fluorescence-based AQUA platform. The result was validated using an independent retrospective metastatic breast cancer cohort (n=130).Results:Epidermal growth factor receptor assessed as a continuous (logarithmic transformed) variable shows an association with disease-free survival in Arm C (P=0.009) but not in Arm A or B. High EGFR expression was associated with worse outcome (Hazard ratio (HR)=2.15; 95% CI 1.28–3.60, P=0.004). Validation in a Greek metastatic breast cancer cohort showed an HR associated with high EGFR expression of 1.92 (P=0.0073).Conclusions:High expression of EGFR appears to be associated with decreased benefit from adjuvant concurrent trastuzumab. Since other treatment options exist for HER2-driven tumours, further validation of these data may select patients for alternative or additive therapy.
