Heat transfer over an unsteady porous stretching surface embedded in a porous medium with variable heat flux in the presence of heat source or sink

The unsteady boundary layer flow over a porous stretching surface embedded in a porous medium in the presence of heat source or sink is studied. The unsteadiness in the flow and temperature fields is caused by the time dependence of the stretching velocity and the surface heat flux. The governing partial differential equations are transformed into a system of ordinary differential equations, which is then solved numerically by applying shooting method using Runge-Kutta method. The solution is found to be dependent on the governing parameters including the Prandtl number, porous parameter, heat source /sink parameter, suction or injection parameter and unsteadiness parameter. Comparison of numerical results is made with previously published results under the special cases, and found to be in good agreement. Effects of the Prandtl number, porous parameter, heat source /sink parameter, suction or injection parameter and unsteadiness parameter on the flow and heat transfer are examined.
Prevalence and Predictors of Low Sexual Desire, Sexually Related Personal Distress, and Hypoactive Sexual Desire Dysfunction in a Community-Based Sample of Midlife Women.

BACKGROUND
Low desire is the most common sexual problem in women at midlife. Prevalence data are limited by lack of validated instruments or exclusion of un-partnered or sexually inactive women.


AIM
To document the prevalence of and factors associated with low desire, sexually related personal distress, and hypoactive sexual desire dysfunction (HSDD) using validated instruments.


METHODS
Cross-sectional, nationally representative, community-based sample of 2,020 Australian women 40 to 65 years old.


OUTCOMES
Low desire was defined as a score no higher than 5.0 on the desire domain of the Female Sexual Function Index (FSFI); sexually related personal distress was defined as a score of at least 11.0 on the Female Sexual Distress Scale-Revised; and HSDD was defined as a combination of these scores. The Menopause Specific Quality of Life Questionnaire was used to document menopausal vasomotor symptoms. The Beck Depression Inventory-II was used to identify moderate to severe depressive symptoms (score ≥ 20).


RESULTS
The prevalence of low desire was 69.3% (95% CI = 67.3-71.3), that of sexually related personal distress was 40.5% (95% CI = 38.4-42.6), and that of HSDD was 32.2% (95% CI = 30.1-34.2). Of women who were not partnered or sexually active, 32.4% (95% CI = 24.4-40.2) reported sexually related personal distress. Factors associated with HSDD in an adjusted logistic regression model included being partnered (odds ratio [OR] = 3.30, 95% CI = 2.46-4.41), consuming alcohol (OR = 1.48, 95% CI = 1.16-1.89), vaginal dryness (OR = 2.08, 95% CI = 1.66-2.61), pain during or after intercourse (OR = 1.63, 95% CI = 1.27-2.09), moderate to severe depressive symptoms (OR = 2.69, 95% CI 1.99-3.64), and use of psychotropic medication (OR = 1.42, 95% CI = 1.10-1.83). Vasomotor symptoms were not associated with low desire, sexually related personal distress, or HSDD.


CLINICAL IMPLICATIONS
Given the high prevalence, clinicians should screen midlife women for HSDD.


STRENGTHS AND LIMITATIONS
Strengths include the large size and representative nature of the sample and the use of validated tools. Limitations include the requirement to complete a written questionnaire in English. Questions within the FSFI limit the applicability of FSFI total scores, but not desire domain scores, in recently sexually inactive women, women without a partner, and women who do not engage in penetrative intercourse.


CONCLUSIONS
Low desire, sexually related personal distress, and HSDD are common in women at midlife, including women who are un-partnered or sexually inactive. Some factors associated with HSDD, such as psychotropic medication use and vaginal dryness, are modifiable or can be treated with safe and effective therapies.

Evaluation of prediction strategy and care coordination for COPD readmissions.

OBJECTIVES
Factors that influence the likelihood of readmission for chronic obstructive pulmonary disease (COPD) patients and the impact of posthospital care coordination remain uncertain. LACE index (L = length of stay, A = Acuity of admission; C = Charlson comorbidity index; E = No. of emergency department (ED) visits in last 6 months) is a validated tool for predicting 30-days readmissions for general medicine patients. We aimed to identify variables predictive of COPD readmissions including LACE index and determine the impact of a novel care management process on 30-day all-cause readmission rate.


METHODS
In a case-control design, potential readmission predictors including LACE index were analyzed using multivariable logistic regression for 461 COPD patients between January-October 2013. Patients with a high LACE index at discharge began receiving care coordination in July 2013. We tested for association between readmission and receipt of care coordination between July-October 2013. Care coordination consists of a telephone call from the care manager who: 1) reviews discharge instructions and medication reconciliation; 2) emphasizes importance of medication adherence; 3) makes a follow-up appointment with primary care physician within 1-2 weeks and; 4) makes an emergency back-up plan.


RESULTS
COPD readmission rate was 16.5%. An adjusted LACE index of ≥ 13 was not associated with readmission (p = 0.186). Significant predictors included female gender (odds ratio [OR] 0.51, 95% confidence interval [CI] 0.29-0.91, p = 0.021); discharge to skilled nursing facility (OR 3.03, 95% CI 1.36-6.75, p = 0.007); 4-6 comorbid illnesses (OR 9.21, 95% CI 1.17-76.62, p = 0.035) and ≥ 4 ED visits in previous 6 months (OR 6.40, 95% CI 1.25-32.87, p = 0.026). Out of 119 patients discharged between July-October 2013, 41% received the care coordination. The readmission rate in the intervention group was 14.3% compared to 18.6% in controls (p = 0.62).


CONCLUSIONS
Factors influencing COPD readmissions are complex and poorly understood. LACE index did not predict 30-days all-cause COPD readmissions. Posthospital care coordination for transition of care from hospital to the community showed a 4.3% reduction in the 30-days all-cause readmission rate which did not reach statistical significance (p = 0.62).
Three-weekly docetaxel with prednisone is feasible for Japanese patients with hormone-refractory prostate cancer: a retrospective comparative study with weekly docetaxel alone.

BACKGROUND
We previously reported that weekly treatment with docetaxel alone is useful for and well tolerated by patients with hormone-refractory prostate cancer (HRPC). Here, we compare it with the regimen of docetaxel once every 3 weeks (q3w) plus daily prednisone (PSL) based on a TAX 327 trial in order to clarify the efficacy and toxicity of docetaxel regimens in Japan.


METHODS
Thirty-two patients with HRPC were treated with docetaxel weekly (regimen 1) or docetaxel q3w plus PSL daily (regimen 2) at Tsukuba University Hospital and the changes in serum prostate-specific antigen (PSA), tumor size and survival were evaluated. The dose of docetaxel in regimen 1 was based on our previous report and that of regimen 2 was modified from a TAX 327 trial.


RESULTS
A >50% decrease in PSA was observed in 53% of the patients with a median time to progression of 3.5 months and 69% with 8.5 months with regimens 1 and 2, respectively. Patients who received regimen 2 had a significantly better survival rate than those who received regimen 1. Myelosuppression and neuropathy were statistically more frequent in regimen 2 than in regimen 1.


CONCLUSION
A regimen of docetaxel q3w with PSL daily was associated with a high rate of PSA reduction and prolongation of patient survival. Although docetaxel has not been approved in Japan yet, this treatment is considered feasible for Japanese patients with HRPC.
Design and modelling of different SRAM's based on CNTFET 32nm technology

Carbon nanotube field-effect transistor (CNTFET) refers to a field-effect transistor that utilizes a single carbon nanotube or an array of carbon nanotubes as the channel material instead of bulk silicon in the traditional MOSFET structure. Since it was first demonstrated in 1998, there have been tremendous developments in CNTFETs, which promise for an alternative material to replace silicon in future electronics. Carbon nanotubes are promising materials for the nano-scale electron devices such as nanotube FETs for ultra-high density integrated circuits and quantum-effect devices for novel intelligent circuits, which are expected to bring a breakthrough in the present silicon technology. A Static Random Access Memory (SRAM) is designed to plug two needs: i) The SRAM provides as cache memory, communicating between central processing unit and Dynamic Random Access Memory (DRAM). ii) The SRAM technology act as driving force for low power application since SRAM is portable compared to DRAM, and SRAM doesn’t require any refresh current. On the basis of acquired knowledge, we present different SRAM's designed for the conventional CNTFET. HSPICE simulations of this circuit using Stanford CNTFET model shows a great improvement in power saving.
Robust image transmission over ATM networks based on scalable wavelet coding

Wen-Jyi Hwang Chung-Kun Wu Ching-Fung Chine Chung Yuan Christian University Department of Electrical Engineering Chungli, 32023 Taiwan E-mail: whwang@dec.ee.cycu.edu.tw Abstract. We present a novel method for scalable and robust image transmission over ATM networks. The algorithm is based on a scalable set partitioning in hierarchical trees (SSPIHT) coding scheme, in which the encoded image bit streams for packeting and transmission are divided into a number of layers. By accumulating different numbers of layers in the decoder side, images with different resolutions and distortions can be reconstructed. Decoders having different capacities therefore can share the same encoder. In addition, these layers have different degrees of significance so that transmission errors in insignificant layers will not cause severe degradation in performance for image reconstruction. Finally, we describe three basic schemes for the transmission of SSPIHT-encoded cells over ATM channels. Simulation results show that the algorithm is effective for the applications where robust and scalable transmissions are desired. © 2002 Society of Photo-Optical Instrumentation Engineers.

A phase advanced commutation scheme for IPM-BLDC motor drives

This paper presents a phase advanced commutation scheme for IPM-BLDC motor drives. In order to utilize the torque capability of an IPM-BLDC motor as much as possible for a low cost and information limited drive, the inverter gating time is advanced such that the phase angle of the stator current can lead that of the corresponding back-emf. Hence the reluctance torque of an IPM-BLDC can be developed properly. The motor electric parameters, rotor speed as well as the inverter switching duty cycle are used to determine the advanced angle instead of look up table method or complicated evaluation scheme. Experimental results show that the proposed scheme can achieve higher efficiency and more extended speed range than the conventional control scheme does.
Leaf Classification Using Shape, Color, and Texture Features

Several methods to identify plants have been proposed by several researchers. Commonly, the methods did not capture color information, because color was not recognized as an important aspect to the identification. In this research, shape and vein, color, and texture features were incorporated to classify a leaf. In this case, a neural network called Probabilistic Neural network (PNN) was used as a classifier. The experimental result shows that the method for classification gives average accuracy of 93.75% when it was tested on Flavia dataset, that contains 32 kinds of plant leaves. It means that the method gives better performance compared to the original work. Keywords—Color features, Foliage plants, Lacunarity, Leaf classification, PFT, PNN, Texture features.
Discrimination of face identities and expressions in children with autism: Same or different?

Autism is a pervasive developmental disorder (PDD) characterized by the association of communication and socialization impairments, and by repetitive stereotyped behaviours. The Minnesota Test of Affective Processing (MNTAP) was used to investigate the discrimination of face identities and face expressions by autistic children. Young children in the 6- to 10-year-old age range suffering from PDD were compared to paired normal children. When the expressions on faces remained neutral, autistic patients had more difficulty in distinguishing different faces than in matching the same facial identities in face pairs: they perceived different faces as being identical. However, recognition errors disappeared when expressions were changed together with face identity. When autistic children were asked to distinguish expressions, they discriminated better identity than difference, just as normal children do. Analysis of face and expression discrimination in terms of identity and difference is a novel approach for the understanding of the clinical features of autism. Autistic children seek sameness and use an atypical strategy to analyse human faces and expressions.

The spectrum of laser skin resurfacing: nonablative, fractional, and ablative laser resurfacing.

UNLABELLED
The drive to attain cosmetic facial enhancement with minimal risk and rapid recovery has inspired the field of nonsurgical skin rejuvenation. Laser resurfacing was introduced in the 1980s with continuous wave carbon dioxide (CO(2)) lasers; however, because of a high rate of side effects, including scarring, short-pulse, high-peak power, and rapidly scanned, focused-beam CO(2) lasers and normal-mode erbium-doped yttrium aluminium garnet lasers were developed, which remove skin in a precisely controlled manner. The prolonged 2-week recovery time and small but significant complication risk prompted the development of non-ablative and, more recently, fractional resurfacing in order to minimize risk and shorten recovery times. Nonablative resurfacing produces dermal thermal injury to improve rhytides and photodamage while preserving the epidermis. Fractional resurfacing thermally ablates microscopic columns of epidermal and dermal tissue in regularly spaced arrays over a fraction of the skin surface. This intermediate approach increases efficacy as compared to nonablative resurfacing, but with faster recovery as compared to ablative resurfacing. Neither nonablative nor fractional resurfacing produces results comparable to ablative laser skin resurfacing, but both have become much more popular than the latter because the risks of treatment are limited in the face of acceptable improvement.


LEARNING OBJECTIVES
At the completion of this learning activity, participants should be familiar with the spectrum of lasers and light technologies available for skin resurfacing, published studies of safety and efficacy, indications, methodologies, side effects, complications, and management.
Gesture spotting with body-worn inertial sensors to detect user activities

We present a method for spotting sporadically occurring gestures in a continuous data stream from body-worn inertial sensors. Our method is based on a natural partitioning of continuous sensor signals and uses a two-stage approach for the spotting task. In a first stage, signal sections likely to contain specific motion events are preselected using a simple similarity search. Those preselected sections are then further classified in a second stage, exploiting the recognition capabilities of hidden Markov models. Based on two case studies, we discuss implementation details of our approach and show that it is a feasible strategy for the spotting of various types of motion events. 2007 Elsevier Ltd.

Intelligent prognostics tools and e-maintenance

In today’s global competitive marketplace, there is intense pressure for manufacturing industries to continuously reduce and eliminate costly, unscheduled downtime and unexpected breakdowns. With the advent of Internet and tether-free technologies, companies necessitate dramatic changes in transforming traditional ‘‘fail and fix (FAF)’’ maintenance practices to a ‘‘predict and prevent (PAP)’’ e-maintenance methodology. Emaintenance addresses the fundamental needs of predictive intelligence tools to monitor the degradation rather than detecting the faults in a networked environment and, ultimately to optimize asset utilization in the facility. This paper introduces the emerging field of e-maintenance and its critical elements. Furthermore, performance assessment and prediction tools are introduced for continuous assessment and prediction of a particular product’s performance, ultimately enable proactive maintenance to prevent machine from breakdowns. Recent advances on intelligent prognostic technologies and tools are discussed. Several case studies are introduced to validate these developed technologies and tools. # 2006 Elsevier B.V.

A double-blind study of paliperidone palmitate and risperidone long-acting injectable in adults with schizophrenia

This 13-week double-blind study was designed to assess noninferiority of the recently approved (in the U.S.) injectable atypical antipsychotic paliperidone palmitate (PP) versus risperidone long-acting injectable (RIS-LAI) in adult patients with schizophrenia. Patients (N=1220) were randomized (1:1) to either a) PP: deltoid injections on day 1 (150 mg eq.), day 8 (100 mg eq.), and once-monthly flexible dosing as deltoid or gluteal injections on day 36 (50 mg eq. or 100 mg eq.) and day 64 (50 mg eq. or 100 mg eq. or 150 mg eq.) or b) RIS-LAI: gluteal injections days 8 and 22 (25mg), days 36, 50 (25 or 37.5mg) and days 64, 78 (25, 37.5 or 50mg). RIS-LAI-treated patients received oral supplementation with RIS 1-6 mg/day (days 1 to 28), and PP-treated patients received oral placebo. The safety analysis set (n=1214) included 58% men, 78% white, with mean (SD) baseline PANSS total score: PP, 84.1 (12.09); and RIS-LAI, 83.6 (11.28). Mean (SD) change from baseline to endpoint in PANSS total score decreased similarly in both groups; PP (-18.6 [15.45]) and RIS-LAI (-17.9 [14.24]). PP treatment was noninferior to RIS-LAI (point estimate [95% CI]: 0.4 [-1.62;2.38], per-protocol analysis set [primary analysis]). The tolerability and safety of PP was generally similar to RIS-LAI with no new safety or tolerability findings.
Lung function in adult patients with cystic fibrosis after using the eFlow® rapid for one year

BACKGROUND
The new generation nebuliser PARI eFlow® rapid allows a highly efficient aerosol delivery at reduced inhalation time. However, lung function data during long-term use of this device are not available until now.


METHODS
70 clinically stable adult cystic fibrosis patients participated in this observation study. Lung function tests were performed prospectively 12 weeks after and again 9 to 12 months after switching the inhalation device from a conventional jet nebulizer to the PARI eFlow® rapid. Lung function data were collected retrospectively from the visits 1 year as well as 12 weeks prior to the switch-over. Lung function data for all time points were only available for 59 patients. Treatment time and patient's satification were recorded for both conventional and new nebuliser in all 70 patients.


RESULTS
After 1 year of inhalation with eFlow® rapid, the mean change in FEV1% was - 1.4% (n = 59 patients). The decrease in FEV1 was smaller than the change in FEV1 after 1 year of inhalation with the conventional jet nebuliser (control period, -3.1%), although this difference was not statistically significant. The same effect was seen in MEF25(%) (-2.6% with conventional nebuliser compared to -1.6% after eFlow® rapid). Concerning the FVC, there was a greater improvement after 1 year of inhalation with the eFlow® rapid than with the jet nebuliser (+ 2.9% vs. +1.1%). For PEF%, there was an increase during the control period, whereas after inhalation with eFlow® rapid there was a decrease (+1.1% vs. -2.9%). All changes were not significantly different. The eFlow® rapid reduced total daily inhalation time by two-thirds (conventional nebuliser: 31.1 min/day; eFlow® rapid: 10.2 min/day, n = 70 patients).


CONCLUSION
Inhalation with the new nebuliser eFlow rapid does not alter FEV1, FVC or PEF significantly after 1 year of inhalation. The treatment time could be reduced significantly by the eFlow® rapid.
