High-performance La-doped BCZT thin film capacitors on LaNiO3/Pt composite bottom electrodes with ultra-high efficiency and high thermal stability

Abstract Dielectric capacitors possessing large energy storage density, high efficiency and high thermal stability simultaneously are very attractive in modern electronic devices to be operated in harsh environment. Here, it is demonstrated that large energy storage density ( W  ∼ 15.5 J/cm 3 ), ultra-high efficiency ( η ∼ 93.7%) and high thermal stability (the variation of both W from 20 °C to 260 °C and η from 20 °C to 140 °C is less than 5%) have been simultaneously achieved in the La-doped (Ba 0.904 Ca 0.096 ) 0.9775+x La 0.015 (Zr 0.136 Ti 0.864 )O 3 (x = 0.0075) lead-free relaxor ferroelectric thin film capacitors deposited on LaNiO 3 /Pt composite bottom electrodes by using a sol-gel method. The good energy storage property of the thin film capacitors at x = 0.0075 is mainly ascribed to the diversity of the structure of the nano-clusters around the three-phases coexisting component point (Ba 0.904 Ca 0.096 )(Zr 0.136 Ti 0.864 )O 3 where cubic, tetragonal and rhombohedral phases coexisted, as well as the ultra-high quality of thin film due to the utilization of the LaNiO 3 /Pt composite bottom electrode, making it a promising candidate for dielectric capacitors working in harsh environments.
Yoga for depression: the research evidence.

BACKGROUND
Yoga-based interventions may prove to be an attractive option for the treatment of depression. The aim of this study is to systematically review the research evidence on the effectiveness of yoga for this indication.


METHODS
Searches of the major biomedical databases including MEDLINE, EMBASE, ClNAHL, PsycINFO and the Cochrane Library were conducted. Specialist complementary and alternative medicine (CAM) and the IndMED databases were also searched and efforts made to identify unpublished and ongoing research. Searches were conducted between January and June 2004. Relevant research was categorised by study type and appraised. Clinical commentaries were obtained for studies reporting clinical outcomes.


RESULTS
Five randomised controlled trials were located, each of which utilised different forms of yoga interventions and in which the severity of the condition ranged from mild to severe. All trials reported positive findings but methodological details such as method of randomisation, compliance and attrition rates were missing. No adverse effects were reported with the exception of fatigue and breathlessness in participants in one study.


LIMITATIONS
No language restrictions were imposed on the searches conducted but no searches of databases in languages other than English were included.


CONCLUSIONS
Overall, the initial indications are of potentially beneficial effects of yoga interventions on depressive disorders. Variation in interventions, severity and reporting of trial methodology suggests that the findings must be interpreted with caution. Several of the interventions may not be feasible in those with reduced or impaired mobility. Nevertheless, further investigation of yoga as a therapeutic intervention is warranted.
Automated discovery, interaction and composition of Semantic Web services

In this paper, we introduce a vision for Semantic Web services which combines the growing Web services architecture and the Semantic Web and we will propose DAML-S as a prototypical example of an ontology for describing Semantic Web services. Furthermore, we show that DAML-S is not just an abstract description, but it can be efficiently implemented to support capability matching and to manage interaction between Web services. Specifically, we will describe the implementation of the DAML-S/UDDI Matchmaker that expands on UDDI by providing semantic capability matching, and we will present the DAML-S Virtual Machine that uses the DAML-S Process Model to manage the interaction with Web service. We will also show that the use of DAML-S does not produce a performance penalty during the normal operation of Web services. © 2003 Elsevier B.V. All rights reserved.

The RegEx trial: a randomized, double-blind, placebo- and active-controlled pilot study combining regadenoson, a selective A(2A) adenosine agonist, with low-level exercise, in patients undergoing myocardial perfusion imaging.

BACKGROUND
Although vasodilator stress myocardial perfusion imaging (MPI) is increasingly performed with exercise, adenosine A(2A) receptor agonists have not been studied with exercise.


OBJECTIVES
To determine the safety of administering regadenoson during exercise and, secondarily, to evaluate image quality, patient acceptance, and detection of perfusion defects.


METHODS
Patients requiring pharmacologic MPI received a standard adenosine-supine protocol (AdenoSup, n = 60) and were then randomized (2:1) in a double-blind manner to low-level exercise with bolus intravenous injection of regadenoson (RegEx, n = 39) or placebo (PlcEx, n = 21).


RESULTS
Adverse events occurred in 95%, 77%, and 33% of patients receiving AdenoSup, RegEx, and PlcEx, respectively. Peak heart rate was 13 beats per minute (bpm) and 21 bpm greater following RegEx compared to that following PlcEx and AdenoSup, respectively (P = .006 and <.001). Change from baseline in mean systolic blood pressure (SBP), change from baseline to nadir SBP, and percentage of patients with a decline in SBP by > or = 20 mm Hg showed no important differences between RegEx and PlcEx. No occurrences of 2nd degree or higher AV block were observed following RegEx or PlcEx; one patient developed 2nd degree AV block following AdenoSup. The mean heart-to-liver and heart-to-gut ratios were improved on RegEx vs AdenoSup: 0.85 (0.34) vs 0.65 (0.26), P < .001 and 1.1 (0.36) vs 0.97 (0.34), P < .001, respectively. Compared to AdenoSup, 70% of patients felt RegEx was much or somewhat better.


CONCLUSIONS
Combining regadenoson with low-level exercise is feasible, well tolerated, and associated with fewer side effects compared to AdenoSup.
A programmable 1.5 V CMOS class-AB operational amplifier with hybrid nested Miller compensation for 120 dB gain and 6 MHz UGF

RADITIONALLY, CMOS operational amplifiers apply T cascoding techniques to ensure an acceptable gain with a minimal number of gain stages. The use of cascodes, however, fundamentally limits the lowest supply voltage at which the amplifier circuit is able to operate. Furthermore, the apparent trend towards lower threshold voltages of CMOS processes endangers the applicability of cascoded circuits in the near future. The two restrictions on the use of cascoded opamps are illustrated by Fig. 1 and Fig. 2 . The most immediate drawback of the cascoded amplifier is its relatively high minimum supply voltage. Fig. 1 presents the simplified schematic of a conventional operational amplifier with a push-pull output stage Ill. It consists of the input stage M3” A& and the output stage iz’!10/Af20 separated by cascode transistors M 2 , and hf2.2. The bold lines indicate the places where the stacked drain-source voltages of two cascode transistors are present on top of the gate-source voltage of an output transistor. The summed saturation voltages of the cascodes raise the lowest supply voltage one saturation voltage above the minimum obtainable. The minimum supply voltage of a CMOS operational amplifier is mainly determined by the gate-source voltage of the output transistors under the maximum output current condition. When driving high output currents, the supply voltage must suffice to build up the gatesource voltage of the output transistors plus the loss in the driving circuit. The two cascode devices account for a loss equal to their two summed saturation voltages. The minimum supply voltage Vn,iL, is therefore given by
Transcatheter aortic valve implantation: first results from a multi-centre real-world registry.

AIMS
Treatment of elderly symptomatic patients with severe aortic stenosis and co-morbidities is challenging. Transcatheter aortic valve interventions [balloon valvuloplasty and transcatheter aortic valve implantation (TAVI)] are evolving as alternative treatment options to surgical valve replacement. We report the first results of the prospective multi-centre German Transcatheter Aortic Valve Interventions-Registry.


METHODS AND RESULTS
Between January 2009 and December 2009, a total of 697 patients (81.4 ± 6.3 years, 44.2% males, and logistic EuroScore 20.5 ± 13.2%) underwent TAVI. Pre-operative aortic valve area was 0.6 ± 0.2 cm² with a mean transvalvular gradient of 48.7 ± 17.2 mmHg. Transcatheter aortic valve implantation was performed percutaneously in the majority of patients [666 (95.6%)]. Only 31 (4.4%) procedures were done surgically: 26 (3.7%) transapically and 5 (0.7%) transaortically. The Medtronic CoreValve™ prosthesis was used in 84.4%, whereas the Sapien Edwards™ prosthesis was used in the remaining cases. Technical success was achieved in 98.4% with a post-operative mean transaortic pressure gradient of 5.4 ± 6.2 mmHg. Any residual aortic regurgitation was observed in 72.4% of patients, with a significant aortic insufficiency (≥Grade III) in only 16 patients (2.3%). Complications included pericardial tamponade in 1.8% and stroke in 2.8% of patients. Permanent pacemaker implantation after TAVI became necessary in 39.3% of patients. In-hospital death rate was 8.2%, and the 30-day death rate 12.4%.


CONCLUSION
In this real-world registry of high-risk patients with aortic stenosis, TAVI had a high success rate and was associated with moderate in-hospital complications. However, careful patient selection and continued hospital selection seem crucial to maintain these results.
MEMS-based micropumps in drug delivery and biomedical applications

This paper briefly overviews progress on the development of MEMS-based micropumps and their applications in drug delivery and other iomedical applications such as micrototal analysis systems ( TAS) or lab-on-a-chip and point of care testing systems (POCT). The focus of the eview is to present key features of micropumps such as actuation methods, working principles, construction, fabrication methods, performance arameters and their medical applications. Micropumps have been categorized as mechanical or non-mechanical based on the method by which ctuation energy is obtained to drive fluid flow. The survey attempts to provide a comprehensive reference for researchers working on design nd development of MEMS-based micropumps and a source for those outside the field who wish to select the best available micropump for a pecific drug delivery or biomedical application. Micropumps for transdermal insulin delivery, artificial sphincter prosthesis, antithrombogenic icropumps for blood transportation, micropump for injection of glucose for diabetes patients and administration of neurotransmitters to neurons nd micropumps for chemical and biological sensing have been reported. Various performance parameters such as flow rate, pressure generated nd size of the micropump have been compared to facilitate selection of appropriate micropump for a particular application. Electrowetting, lectrochemical and ion conductive polymer film (ICPF) actuator micropumps appear to be the most promising ones which provide adequate flow ates at very low applied voltage. Electroosmotic micropumps consume high voltages but exhibit high pressures and are intended for applications here compactness in terms of small size is required along with high-pressure generation. Bimetallic and electrostatic micropumps are smaller n size but exhibit high self-pumping frequency and further research on their design could improve their performance. Micropumps based on iezoelectric actuation require relatively high-applied voltage but exhibit high flow rates and have grown to be the dominant type of micropumps n drug delivery systems and other biomedical applications. Although a lot of progress has been made in micropump research and performance of icropumps has been continuously increasing, there is still a need to incorporate various categories of micropumps in practical drug delivery and iomedical devices and this will continue to provide a substantial stimulus for micropump research and development in future. 2007 Elsevier B.V.

Extreme cerebrospinal fluid amyloid beta levels identify family with late-onset Alzheimer's disease presenilin 1 mutation.

OBJECTIVE
Aggregation and deposition of amyloid beta (Abeta) in the brain is thought to be central to the pathogenesis of Alzheimer's disease (AD). Recent studies suggest that cerebrospinal fluid (CSF) Abeta levels are strongly correlated with AD status and progression, and may be a meaningful endophenotype for AD. Mutations in presenilin 1 (PSEN1) are known to cause AD and change Abeta levels. In this study, we have investigated DNA sequence variation in the presenilin (PSEN1) gene using CSF Abeta levels as an endophenotype for AD.


METHODS
We sequenced the exons and flanking intronic regions of PSEN1 in clinically characterized research subjects with extreme values of CSF Abeta levels.


RESULTS
This novel approach led directly to the identification of a disease-causing mutation in a family with late-onset AD.


INTERPRETATION
This finding suggests that CSF Abeta may be a useful endophenotype for genetic studies of AD. Our results also suggest that PSEN1 mutations can cause AD with a large range in age of onset, spanning both early- and late-onset AD.
Translation, cultural adaptation and validation of the English “Short form SF 12v2” into Bengali in rheumatoid arthritis patients

BACKGROUND
To develop a culturally adapted and validated Bengali Short Form SF 12v2 among Rheumatoid arthritis (RA) patients.


METHODS
The English SF 12v2 was translated, adapted and back translated into and from Bengali, pre-tested by 60 patients. The Bengali SF 12v2 was administered twice with 14 days interval to 130 Bangladeshi RA patients. The psychometric properties of the Bengali SF 12v2 were assessed. Test-retest reliability was assessed by intra-class correlation coefficient (ICC) and Spearman's rank correlation coefficient and internal consistency by Cronbach's alpha. Content validity was assessed by index for content validity (ICV) and floor and ceiling effects. To determine convergent and discriminant validity a Bengali Health Assessment Questionnaire (B-HAQ) was used. Factor analysis was done.


RESULTS
The Bengali SF 12v2 was well accepted by the patients in the pre-test and showed good reliability. Internal consistency for both physical and mental component was satisfactory; Cronbach's alpha was 0.9. ICC exceeded 0.9 in all domains. Spearman's rho for all domains exceeded 0.8. The physical health component of Bengali SF 12v2 had convergent validity to the B-HAQ. Its mental health component had discriminant validity to the B-HAQ. The ICV of content validity was 1 for all items. Factor analysis revealed two factors a physical and a mental component.


CONCLUSIONS
The interviewer-administered Bengali SF 12v2 appears to be an acceptable, reliable, and valid instrument for measuring health-related quality of life in Bengali speaking RA patients. Further evaluation in the general population and in different medical conditions should be done.

Infliximab (REMICADE) Therapy in the Treatment of Pediatric Crohn's Disease

OBJECTIVES:The aim of this study was to assess the efficacy and safety of a single infusion of infliximab in the treatment of pediatric Crohn's disease (CD).METHODS:A total of 21 pediatric CD patients were enrolled at seven study centers and randomized to receive a single infusion of infliximab 1 mg/kg (n = 6), 5 mg/kg (n = 7), or 10 mg/kg (n = 8) over at least 2 hrs at week 0 in this multicenter, open-label, dose-blinded trial. Efficacy assessments, including the Pediatric Crohn's Disease Activity Index (PCDAI), modified CDAI, C-reactive protein concentration (CRP), and erythrocyte sedimentation rate (ESR) determinations, were made at screening and at weeks 1, 2, 4, 8, and 12. Adverse events were assessed throughout study participation.RESULTS:Improvements in the PCDAI, modified CDAI, ESR, and CRP were observed with all infliximab doses, beginning at week 1. On average, all treated patients experienced approximately 50% improvement in the PCDAI by week 2. By week 12, the PCDAI remained approximately 30% improved from baseline. During the study, all 21 patients (100%) achieved a clinical response, and 10 patients (48%) achieved clinical remission. There were no infusion reactions in any of the treatment arms.CONCLUSIONS:The results of this trial suggest that infliximab may be safe and effective as short-term therapy of medically refractory moderate to severe CD in a pediatric population.
The effect of inter-implant distance on the height of inter-implant bone crest.

BACKGROUND
The biologic width around implants has been well documented in the literature. Once an implant is uncovered, vertical bone loss of 1.5 to 2 mm is evidenced apical to the newly established implant-abutment interface. The purpose of this study was to evaluate the lateral dimension of the bone loss at the implant-abutment interface and to determine if this lateral dimension has an effect on the height of the crest of bone between adjacent implants separated by different distances.


METHODS
Radiographic measurements were taken in 36 patients who had 2 adjacent implants present. Lateral bone loss was measured from the crest of bone to the implant surface. In addition, the crestal bone loss was also measured from a line drawn between the tops of the adjacent implants. The data were divided into 2 groups, based on the inter-implant distance at the implant shoulder.


RESULTS
The results demonstrated that the lateral bone loss was 1.34 mm from the mesial implant shoulder and 1.40 mm from the distal implant shoulder between the adjacent implants. In addition, the crestal bone loss for implants with a greater than 3 mm distance between them was 0.45 mm, while the implants that had a distance of 3 mm or less between them had a crestal bone loss of 1.04 mm.


CONCLUSIONS
This study demonstrates that there is a lateral component to the bone loss around implants in addition to the more commonly discussed vertical component. The clinical significance of this phenomenon is that the increased crestal bone loss would result in an increase in the distance between the base of the contact point of the adjacent crowns and the crest of bone. This could determine whether the papilla was present or absent between 2 implants as has previously been reported between 2 teeth. Selective utilization of implants with a smaller diameter at the implant-abutment interface may be beneficial when multiple implants are to be placed in the esthetic zone so that a minimum of 3 mm of bone can be retained between them at the implant-abutment level.
BTRES: Beta-based Trust and Reputation Evaluation System for wireless sensor networks

Unlike traditional networks, the wireless sensor networks (WSNs) are very vulnerable to internal attacks from compromised nodes. The trust management system is the most effective way to defend the attack inside the network. The Beta-based Trust and Reputation Evaluation System (BTRES) is proposed in this paper for WSNs' node trust and reputation evaluation. BTRES is based on monitoring nodes' behavior, and beta distribution is used to describe the distribution of nodes' credibility. The node trust values are used to guide the selection of relay nodes, mitigating internal attacks risks. Simulation results show that the use of BTRES could effectively maximize the defense of internal attacks from compromised nodes and improve the WSNs' information security. In this paper, we mainly focus on the communication trust and data trust, and energy trust can be easily integrated into BTRES. & 2015 Elsevier Ltd. All rights reserved.
Open system approach to neutrino oscillations

Neutrino oscillations are studied in the general framework of open quantum systems by means of extended dynamics that take into account possible dissipative effects. These new phenomena induce modifications in the neutrino oscillation pattern that in general can be parametrized by means of six phenomenological constants. Although very small, stringent bounds on these parameters are likely to be given by future planned neutrino experiments.
Tics and Tourette: a clinical, pathophysiological and etiological review.

PURPOSE OF REVIEW
Describe developments in the etiological understanding of Tourette syndrome.


RECENT FINDINGS
Tourette syndrome is a complex heterogenous clinical syndrome, which is not a unitary entity. Pathophysiological models describe gamma-aminobutyric acid-ergic-associated disinhibition of cortico-basal ganglia motor, sensory and limbic loops. MRI studies support basal ganglia volume loss, with additional white matter and cerebellar changes. Tourette syndrome cause likely involves multiple vulnerability genes and environmental factors. Only recently have some vulnerability gene findings been replicated, including histidine decarboxylase and neurexin 1, yet these rare variants only explain a small proportion of patients. Planned large genetic studies will improve genetic understanding. The role of inflammation as a contributor to disease expression is now supported by large epidemiological studies showing an association with maternal autoimmunity and childhood infection. Investigation of blood cytokines, blood mRNA and brain mRNA expression support the role of a persistent immune activation, and there are similarities with the immune literature of autistic spectrum disorder. Current treatment is symptomatic, although there is a better appreciation of factors that influence treatment response.


SUMMARY
At present, therapeutics is focused on symptom-based treatments, yet with improved etiological understanding, we will move toward disease-modifying therapies in the future.
