Output-Only Modal Analysis Using Continuous-Scan Laser Doppler Vibrometry and Application to a 20kW Wind Turbine

Continuous-scan laser Doppler vibrometry (CSLDV) is a method whereby one continuously sweeps the laser measurement point over a structure while measuring, in contrast to the conventional scanning LDV approach where the laser spot remains stationary while the response is collected at each point. The continuousscan approach can greatly accelerate measurements, allowing one to capture spatially detailed mode shapes along a scan path in the same amount of time that is typically required to measure the response at a single point. The method is especially beneficial when testing large structures, such as wind turbines, whose natural frequencies are very low and hence require very long time records. Several CSLDV methods have been presented that employ harmonic excitation or impulse excitation, but no prior work has performed CSLDV with an unmeasured, broadband random input. This work extends CSLDV to that class of input, developing an outputonly CSLDV method (OMA-CSLDV). This is accomplished by adapting a recently developed algorithm for linear time-periodic systems to the CSLDV measurements, which makes use of harmonic power spectra and the harmonic transfer function concept developed by Wereley. The proposed method is validated on a randomly excited free-free beam, where one-dimensional mode shapes are captured by scanning the laser along the length of the beam. The natural frequencies and mode shapes are extracted from the harmonic power spectrum of the vibrometer signal and show good agreement with the first seven analytically-derived modes of the beam. The method is then applied to identify the shapes of several modes of a 20kW wind turbine using a ground based laser and with only a light breeze providing excitation.
The avian muscle spindle

The literature on the morphology and physiology of the avian muscle spindle is reviewed, with emphasis placed on the period from 1960 to 1991. Traits similar to or different from mammalian spindles are recognized. Apart from receptors with low intrafusal fiber counts, bird spindles contain two or three types of intrafusal fiber. Unlike that of mammals, the equatorial fiber structure in birds does not lend itself to classification into nuclear bag and nuclear chain types. Avian intrafusal fibers are separable into types based on differences in myosin heavy chain composition and motor innervation, but apportionment of these fiber types to individual spindles is more variable in birds than in mammals. There is morphological evidence in birds for the existence of both gamma and beta innervation; however, confirmation of these systems by physiological experiments is at best sketchy. A general lack of physiological data is currently the greatest drawback to a better understanding of how the avian receptor works, and what role it plays in sensorimotor integration.
Effectiveness of Dynamic Prefetching in Multiple-WriterDistributed Virtual Shared Memory Systems

We consider a network of workstations (NOW) organization consisting of busbased multiprocessors interconnected by an ATM interconnect on which a sharedmemory programming model is imposed by using a multiple-writer distributed virtual shared memory system. The latencies associated with bringing data into the local memory are a severe performance limitation of such systems. To tolerate the access latencies, we propose a novel prefetch approach and show how it can be integrated into the software-based coherence layer of a multiple-writer protocol. This approach uses the access history of each page to guide which pages to prefetch. Based on detailed architectural simulations and seven scientific applications we find that our prefetch algorithm can remove a vast majority of the remote operations which improves the performance of all applications. We also find that the bandwidth provided by ATM switches available today is sufficient to accommodate prefetching. However, the protocol processing overhead of available ATM interfaces limits the gain of the prefetching algorithms.
Validation of the TONOPORT V ambulatory blood pressure monitor according to the European Society of Hypertension International Protocol for Validation of Blood Pressure Measuring Devices in Adults.

BACKGROUND
It is now accepted that blood pressure measuring devices should be subjected to an independent evaluation of their accuracy before they are marketed for clinical use. The results of validation of the TONOPORT V blood pressure monitor for the measurement of ambulatory blood pressure according to the European Society of Hypertension International Protocol for Validation of Blood Pressure Measuring Devices in Adults are presented in this paper.


POPULATION
Thirty-three subjects were recruited from among staff and patients at Beaumont Hospital, Dublin, Ireland.


METHODS
The TONOPORT V monitor was connected to the Sphygmocorder, an audiovisual system for validation, which records blood pressure on tape and video for later analysis. Nine sequential same-arm measurements between the device and a standard mercury sphygmomanometer were recorded using the Sphygmocorder.


RESULTS
In phase 1, the TONOPORT V monitor produced 28 measurements within 5 mmHg, 37 within 10 mmHg and 40 within 15 mmHg for systolic blood pressure (SBP), and 26 within 5 mmHg, 38 within 10 mmHg and 44 within 15 mmHg for diastolic blood pressure (DBP). The mean differences were -2.2 (8.6) [mean (SD)] mmHg for SBP and +0.5 (7.2) mmHg for DBP. The TONOPORT V monitor passed all the criteria for both SBP and DBP. In phase 2.1, the TONOPORT V monitor had 56 measurements within 5 mmHg, 78 within 10 mmHg and 88 within 15 mmHg for SBP, and 60 measurements within 5 mmHg, 83 within 10 mmHg and 97 within 15 mmHg for DBP. The mean differences were -1.4 (8.7) mmHg for SBP and -0.2 (6.8) mmHg for DBP. The TONOPORT V monitor passed the criteria for DBP but failed to meet any of the criteria for SBP. In phase 2.2, 19 subjects had at least two of the differences within 5 mmHg and six subjects had no differences within 5 mmHg for SBP, and 22 subjects had at least two of the differences within 5 mmHg and six subjects no differences within 5 mmHg for DBP. The TONOPORT V monitor failed to meet the criteria for SBP and for DBP.


CONCLUSIONS
The TONOPORT V monitor cannot be recommended for clinical use in an adult population because it records SBP inaccurately and because it records DBP inaccurately in an unacceptably high proportion of people.
Evaluation of environmental bacterial contamination and procedures to control cross infection in a sample of Italian dental surgeries.

OBJECTIVES
To perform a pilot study on bacterial contamination in some dental surgeries (n=51) in a local health unit in Brescia (Lombardy Region, Italy) and to evaluate the procedures to control cross infection used by the personnel to reduce the risk of infection in dental practice.


METHODS
A survey was carried out by interviewing 133 dental personnel with a questionnaire on the procedures used to control infection. The autoclaves, chemical baths (chemiclaves), and ovens present in the surgeries were tested for sterilisation efficiency with a spore test, and already packed and sterilised instruments were randomly sampled and tested for sterility. Microbial contamination of air, surface, and dental unit water samples were also studied.


RESULTS
The dental personnel did not generally follow the principal procedures for infection control: 30% of personnel were not vaccinated against hepatitis B virus, infected instruments were often not decontaminated, periodic checks of autoclave efficiency were lacking, and the knowledge of disinfection mechanisms and procedures was incomplete. High bacteriological contamination of water at dental surgeries was often found and total bacteriological counts in air samples were high. Surface studies showed widespread bacterial contamination.


CONCLUSIONS
On the basis of these results, an educational programme for the prevention of infective hazards has been prepared and carried out. The results of this pilot study will be used for planning a national survey.
Playfulness in children with and without disability: measurement and intervention.

OBJECTIVE
The differences in playfulness between young children with cerebral palsy and developmental delays and children who are typically developing, and the comparative effects of two interventions (one focused on improving mother-child interaction patterns, the other a neurodevelopmental treatment [NDT] session) on children's playfulness were examined in this study. Reliability and validity of the Test of Playfulness (ToP) also were examined.


METHOD
Three trained raters used the ToP to score 38 children, half with cerebral palsy and developmental delays and half typically developing, as they played with their mothers. Mental ages of the children ranged from 3 to 18 months. The mother-child dyads in which the children had cerebral palsy and developmental delays were then randomly assigned to an intervention group. After a 1-hr intervention to improve mother-child interaction, the children were rescored on the ToP.


RESULTS
After examination of ToP reliability and validity, children with cerebral palsy and developmental delays were found to score significantly lower on the ToP than their peers who were typically developing. In addition, children whose mothers received an intervention to improve mother-child interactions scored significantly higher on the ToP after intervention than before intervention. However, the gain scores of children whose mothers received the intervention were not significantly higher than those of children who received direct NDT.


CONCLUSION
The results suggested that when the shared goal of parents and therapists is to enable children to express their inherent playfulness, intervention to improve parent-child interactions may be more potent than intervention directed at improving the child's developmental skills.
Antecedents of mothers' emotional and cognitive responses to infant distress: The role of family, mother, and infant characteristics.

The antecedents of mothers' emotional and cognitive responses to infant distress were examined. Participants were 67 mothers and their infants. Mothers completed questionnaires assessing their experiences in the family of origin and current marital relationships both pre- and postnatally and their coping strategies prenatally. Infant temperament was observed at 6 months, and mothers were interviewed about their emotional and cognitive responses to infant distress 2 years later to assess their emotional competencies (i.e., accurate identification of negative emotions, emotion efficacy, emotional responses to infant distress, and emotion goals). A childhood history of emotional rejection was negatively associated with empathy and efficacy and positively associated with negative emotions. The association between childhood history and some emotional competencies was moderated by current marital dysfunction, engaged coping, and positive intervening relationships. Maternal marital styles and coping strategies and infant temperament correlated with emotional competencies. Theoretical and clinical implications are discussed from an attachment theory perspective.
Accounting and capital markets: a survey of the European evidence

The relationship between accounting information and capital markets has been the subject of numerous studies, especially in the US. The purpose of this article is to examine the corresponding evidence in Europe. This review classi es the European literature into three groups: studies of the market reaction to newly released accounting information; studies of the long-term association between stock returns and accounting numbers; studies devoted to the use of accounting data by investors and to the impact of market pressure on accounting choices. The paper reviews and summarizes the main results related to each of these topics. It also addresses some methodological issues and provides suggestions for future research.
The problem of identifying misogynist language on Twitter (and other online social spaces)

Misogynist abuse has now become serious enough to attract attention from scholars of Law [7]. Social network platform providers have been forced to address this issue, such that Twitter is now very clear about what constitutes abusive behaviour, and has responded by updating their trust and safety rules [16].
Data structures in the multicore age

The advent of multicore processors as the standard computing platform will force major changes in software design.
In vitro study of ethosome penetration in human skin and hypertrophic scar tissue.

The purpose of this study is to characterize a novel transdermal delivery carrier, ethosomes containing 5-fluorouracil. The delivery of drugs from ethosomes in human hypertrophic scar (HS) and the mechanisms of action of ethosomes in human HS were investigated. Percutaneous ethosome permeation was evaluated in vitro in human HS and skin using a Franz's cell. The amount of 5-fluorouracil that permeated HS and skin after 24 hours was most abundant in ethosomes via HS (E-Scar), followed by hydroethanolic solution via HS (H-Scar), ethosomes via skin (E-Skin), and hydroethanolic solution via skin (H-Skin). The penetration of ethosomes in HS and skin was analyzed by ethosomes fluorescently labeled with rhodamine 6GO using confocal laser scanning microscopy. The fluorescence intensity after application for 24 hours was highest in E-Scar, followed by E-Skin, H-Scar, and H-Skin, which indicates the penetration of ethosomes in HS was greatest. In conclusion, we consider that ethosomes are a highly efficient carrier in HS.
Barriers to cervical cancer screening in women attending the Family Medical Program in Niterói, Rio de Janeiro

The Family Medical Program is a health care system in the Rio de Janeiro state. Women’s health services offered by the Family Medical Program include preventive exams and screening, family planning, and prenatal follow-up. Although cervical cancer screening is offered, barriers to care still hinder the full success of the program, and we are attempting to identify these barriers. We undertook a cross-sectional and prospective study involving 351 women who were referred to the Family Medical Program between March 2009 and November 2010. Demographic data were obtained through a structured household questionnaire. The dependent variable was defined as the non-realization of the Pap smear test following the protocol of the Health Ministry. Cervical samples for screening were collected after clinical examination. Women who had undergone Pap smear testing at least once every 3 years comprised 282 of the participants (80.3 %). Most of the women had normal or inflammatory cytology (96.3 %). Illiteracy and the absence of symptomatic episodes of sexually transmitted disease were independent barriers to having cancer screening at regular intervals. Illiterate women were more likely to be older, not to be using any contraceptive method, and on average had more than two children, more than four pregnancies, and more than two abortions. Embarrassment was the greatest barrier to seeking professional care reported by all women, regardless of level of educational attainment. Other important barriers to seeking care and/or screening included time constraints, due to work or childcare. This study indicates that the Family Medical Program effectively provides cervical cancer screening coverage for its eligible population, at the level mandated by the WHO and the Brazilian Health Ministry. Fully 96.3 % of the women in our study had normal or benign inflammation on cytology. Understanding of barriers to care-seeking behavior that limit program adherence is one way to facilitate communication between providers and patients regarding the benefits of cancer screening.
Endoscopic-assisted probing for congenital nasolacrimal duct obstruction

PurposeTo determine the success rate of initial probing in children with congenital nasolacrimal duct obstruction (CNLDO) at different ages using nasal endoscopy, and to identify the anatomical sites of blockage within the drainage system.MethodsA total of 87 eyes from 67 consecutive children with CNLDO underwent endoscopic nasolacrimal duct (NLD) probing under general anaesthetic. Patients who had had previous probings were excluded from the study. Diagnosis was based on history of epiphora since birth or shortly after, and fluorescein dye disappearance test (FDDT). Cure was judged as complete or near-complete remission of symptoms and signs and a normal FDDT.ResultsThe age range was 12–91 months (mean 32.3 months). The success rates of probing were: 100% (58/58) for atresia and stenosis at the lower NLD, 100% (13/13) for punctal stenosis, 55.6% (5/9) for functional epiphora, and 0% (0/7) for canalicular and upper NLD obstruction. Age was not found to significantly affect the outcome of probing, whereas site did. Obstruction at canalicular or upper NLD level became more common with increasing age.ConclusionProbing of the nasolacrimal system using the endoscopic approach allows direct visualisation of the distal nasolacrimal duct, which facilitates diagnosis of the anomaly at this site. More complex proximal anomalies became increasingly prevalent in older children, which accounted for the poorer results with increasing age. Site of obstruction has a greater bearing on outcome than patient age.
Transition of care from child to adult mental health services: the great divide.

PURPOSE OF REVIEW
Adolescents with mental health problems often require transition of care from child and adolescent to adult mental health services. This review is a synthesis of current research and policy literature on transition to describe the barriers at the interface between child and adolescent mental health services and adult mental health services and outcomes of poor transition.


RECENT FINDINGS
Adolescence is a risk period for emergence of serious mental disorders. Child and adolescent mental health services and adult mental health services use rigid age cut-offs to delineate service boundaries, creating discontinuities in provision of care. Adolescent mental health services are patchy across the world. Several recent studies have confirmed that problems occur during transition in diverse settings across several countries. In physical health, there are emerging models of practice to improve the process and outcomes of transition, but there is very little comparable literature in mental healthcare.


SUMMARY
Poor transition leads to disruption in continuity of care, disengagement from services and is likely to lead to poorer clinical outcomes. Some young people, such as those with neurodevelopmental disorders and complex needs, are at a greater risk of falling through the care gap during transition. Services need robust and high-quality evidence on the process and outcomes of transition so that effective intervention strategies can be developed.
Trajectories of change in emotion regulation and social anxiety during cognitive-behavioral therapy for social anxiety disorder.

UNLABELLED
Cognitive-behavioral therapy (CBT) for social anxiety disorder (SAD) may decrease social anxiety by training emotion regulation skills. This randomized controlled trial of CBT for SAD examined changes in weekly frequency and success of cognitive reappraisal and expressive suppression, as well as weekly intensity of social anxiety among patients receiving 16 weekly sessions of individual CBT. We expected these variables to (1) differ from pre-to-post-CBT vs. Waitlist, (2) have differential trajectories during CBT, and (3) covary during CBT. We also expected that weekly changes in emotion regulation would predict (4) subsequent weekly changes in social anxiety, and (5) changes in social anxiety both during and post-CBT. Compared to Waitlist, CBT increased cognitive reappraisal frequency and success, decreased social anxiety, but had no impact on expressive suppression. During CBT, weekly cognitive reappraisal frequency and success increased, whereas weekly expressive suppression frequency and social anxiety decreased. Weekly decreases in social anxiety were associated with concurrent increases in reappraisal success and decreases in suppression frequency. Granger causality analysis showed that only reappraisal success increases predicted decreases in subsequent social anxiety during CBT. Reappraisal success increases pre-to-post-CBT predicted reductions in social anxiety symptom severity post-CBT. The trajectory of weekly changes in emotion regulation strategies may help clinicians understand whether CBT is effective and predict decreases in social anxiety.

Impact of prior virological failure and nucleos(t)ide genotypic resistance mutations on the efficacy of switching from ritonavir-boosted protease inhibitors to raltegravir.

BACKGROUND
The virological efficacy of switching from a ritonavir-boosted protease inhibitor (PI/r)- to a raltegravir (RAL)-containing regimen remains controversial according to the results of SWITCHMRK and SPIRAL studies. The aim of this analysis is to assess the impact of prior resistance mutations to nucleos(t)ides and other potential factors on the virological outcome.


METHODS
This was a substudy of the prospective, open-label, multicentre SPIRAL study. Demographic, virological variables, prior episodes of virological failures (VF) and archived resistance mutations to nucleos(t)ides were identified from databases and its impact measured by genotypic sensitive scores (GSS) according to the genotypic resistance interpretation algorithm from the Stanford HIV Drug Resistance Database on outcome was analysed.


RESULTS
Of 250 patients (128 RAL and 122 PI/r) included in the main SPIRAL study, 74 (30%) had previous VF with prior genotypic resistance tests (GRT). Median time of virological suppression prior to inclusion in SPIRAL study was 63.5 months. GSS for backbone nucleos(t)ides was <1 in 15/38 (39%) in the RAL arm and in 9/36 (25%) in the PI/r arm (P=0.13). Among those with nucleos(t)ides GSS <1, 0/15 (0%) in the RAL versus 2/9 (22%) in the PI/r arm developed VF (P=0.13). Moreover 0/11 subjects with null or residual (GSS≤0.5) backbone activity developed VF in the RAL arm.


CONCLUSIONS
The 48-week virological efficacy of switching from a PI/r to RAL in subjects with long-term virological suppression was not compromised by a reduction of the nucleos(t)ide backbone activity.
A PARAMETER DESIGN STUDY IN A TURNING OPERATION USING THE TAGUCHI METHOD

Modern manufacturers, seeking to remain competitive in the market, rely on their manufacturing engineers and production personnel to quickly and effectively set up manufacturing processes for new products. Taguchi Parameter Design is a powerful and efficient method for optimizing quality and performance output of manufacturing processes, thus a powerful tool for meeting this challenge. This paper discusses an investigation into the use of Taguchi Parameter Design for optimizing surface roughness generated by a CNC turning operation. This study utilizes a standard orthogonal array for determining the optimum turning parameters, with an applied noise factor. Controlled factors include spindle speed, feed rate, and depth of cut; and the noise factor is slightly damaged jaws. The noise factor is included to increase the robustness and applicability of this study. After experimentally turning sample workpieces using the selected orthogonal array and parameters, this study produced a verified combination of controlled factors and a predictive equation for determining surface roughness with a given set of parameters.
