Identification and Robust Control of DC/DC Converter Hammerstein Model

This paper deals with model-based robust control of DC/DC power electronic converters. The converter is described by means of a Hammerstein model consisting of the nonlinear static characteristics of the converter and a linear time-invariant (LTI) uncertain model whose parameters depend on the actual duty-cycle operating range. This suggests that the controller be designed using robust control techniques. In view of applying robust control, identification of the earlier LTI models is performed by means of simulation experiments, carried out on a converter switching model implemented on MATLAB/SIMULINK environment. Internal model control (IMC) structure is employed for the controller design, but its implementation is performed using the equivalent feedback control structure. Comparison with some controllers designed starting from models that do not require identification steps is performed with the aim of showing the advantages connected to the availability of a suitable model, which describes the essential aspects of the behavior of the system, for control purposes. Comparison with a PI controller designed by means of phase margin assignment is carried out with the aim of justifying the use of more sophisticated control methods. Experimental results are also shown that aimed to prove the validity of the whole approach. Comparison of experimental and simulation results is also performed.
Dystrophin‐deficient cardiomyocytes are abnormally vulnerable to mechanical stress‐induced contractile failure and injury

Although absence of the cytoskeletal protein dystrophin leads to dilated cardiomyopathy in humans, the functional role of dystrophin in cardiac muscle remains undefined. We have addressed the hypothesis that dystrophin could help protect the heart against injury and contractile dysfunction induced by mechanical stress. In normal and dystrophin‐deficient (mdx) mice, cardiac mechanical stress was first manipulated ex vivo in a perfused working heart preparation. Despite an afterload level in the normal physiologic range, ex vivo perfused mdx hearts developed severe contractile dysfunction and nonischemic tissue damage, as is shown by excessive LDH release without a rise in coronary lactate. Injury to dystrophin‐deficient hearts was significantly correlated with cardiac work, and reducing the afterload level improved contractility and prevented injury in mdx hearts studied ex vivo. The response to mechanical stress in vivo was also assessed by using the vital dye Evans blue, which penetrates into cardiomyocytes with a disrupted sarcolemma. In the mdx group only, cardiomyocyte injury was increased markedly by acute elevations of mechanical stress induced by isoproterenol or brief aortic occlusion. Strikingly accelerated mortality and cardiac necrosis were also observed in the mdx group subjected to chronically increased cardiac mechanical stress via subtotal aortic constriction. Taken together, our results provide the first direct evidence that dystrophin serves to protect cardiomyocytes from mechanical stress and workload‐induced damage. Accordingly, reducing cardiac work in patients with dystrophin deficiency could be beneficial not only in treating established cardiomyopathy, but also in preventing the onset of cardiac disease.

Update of minimally invasive surfactant therapy

To date, preterm infants with respiratory distress syndrome (RDS) after birth have been managed with a combination of endotracheal intubation, surfactant instillation, and mechanical ventilation. It is now recognized that noninvasive ventilation (NIV) such as nasal continuous positive airway pressure (CPAP) in preterm infants is a reasonable alternative to elective intubation after birth. Recently, a meta-analysis of large controlled trials comparing conventional methods and nasal CPAP suggested that CPAP decreased the risk of the combined outcome of bronchopulmonary dysplasia or death. Since then, the use of NIV as primary therapy for preterm infants has increased, but when and how to give exogenous surfactant remains unclear. Overcoming this problem, minimally invasive surfactant therapy (MIST) allows spontaneously breathing neonates to remain on CPAP in the first week after birth. MIST has included administration of exogenous surfactant by intrapharyngeal instillation, nebulization, a laryngeal mask, and a thin catheter. In recent clinical trials, surfactant delivery via a thin catheter was found to reduce the need for subsequent endotracheal intubation and mechanical ventilation, and improves short-term respiratory outcomes. There is also growing evidence for MIST as an alternative to the INSURE (intubation-surfactant-extubation) procedure in spontaneously breathing preterm infants with RDS. In conclusion, MIST is gentle, safe, feasible, and effective in preterm infants, and is widely used for surfactant administration with noninvasive respiratory support by neonatologists. However, further studies are needed to resolve uncertainties in the MIST method, including infant selection, optimal surfactant dosage and administration method, and need for sedation.
90/900 MHz IC architecture for autonomous systems

In this work we present an IC architecture of RF energy harvesting for wireless sensors networks. By analyzing a probabilistic approach used for modeling the possible amount of Global System for Mobile Communication (GSM) energy that could be harvested, an IC system with a 0. 18μm CMOS SMIC technology has been designed and optimized at 90 and 900 MHz. so to take advantage of the GSM and FM radio radiated energy. Simulation results have confirmed that the integrated system handles an incoming power typically ranging from −25 dBm to 5 dBm by rectifying the variable input signals into a DC voltage source. The overall RF to DC efficiency is about 45% at 90MHz and 55% at 900MHz.
PLASTID MOVEMENT IMPAIRED1 and PLASTID MOVEMENT IMPAIRED1-RELATED1 Mediate Photorelocation Movements of Both Chloroplasts and Nuclei1[OPEN]

Two C2 domain proteins regulate light-mediated movements of plastids and nuclei in both mesophyll and pavement cells. Organelle movement and positioning play important roles in fundamental cellular activities and adaptive responses to environmental stress in plants. To optimize photosynthetic light utilization, chloroplasts move toward weak blue light (the accumulation response) and escape from strong blue light (the avoidance response). Nuclei also move in response to strong blue light by utilizing the light-induced movement of attached plastids in leaf cells. Blue light receptor phototropins and several factors for chloroplast photorelocation movement have been identified through molecular genetic analysis of Arabidopsis (Arabidopsis thaliana). PLASTID MOVEMENT IMPAIRED1 (PMI1) is a plant-specific C2-domain protein that is required for efficient chloroplast photorelocation movement. There are two PLASTID MOVEMENT IMPAIRED1-RELATED (PMIR) genes, PMIR1 and PMIR2, in the Arabidopsis genome. However, the mechanism in which PMI1 regulates chloroplast and nuclear photorelocation movements and the involvement of PMIR1 and PMIR2 in these organelle movements remained unknown. Here, we analyzed chloroplast and nuclear photorelocation movements in mutant lines of PMI1, PMIR1, and PMIR2. In mesophyll cells, the pmi1 single mutant showed severe defects in both chloroplast and nuclear photorelocation movements resulting from the impaired regulation of chloroplast-actin filaments. In pavement cells, pmi1 mutant plants were partially defective in both plastid and nuclear photorelocation movements, but pmi1pmir1 and pmi1pmir1pmir2 mutant lines lacked the blue light-induced movement responses of plastids and nuclei completely. These results indicated that PMI1 is essential for chloroplast and nuclear photorelocation movements in mesophyll cells and that both PMI1 and PMIR1 are indispensable for photorelocation movements of plastids and thus, nuclei in pavement cells.
Screening for abdominal aortic aneurysms: single centre randomised controlled trial

Abstract Objective To determine whether screening Danish men aged 65 or more for abdominal aortic aneurysms reduces mortality. Design Single centre randomised controlled trial. Setting All five hospitals in Viborg County, Denmark. Participants All 12 639 men born during 1921-33 and living in Viborg County. In 1994 we included men born 1921-9 (64-73 years). We also included men who became 65 during 1995-8. Interventions Men were randomised to the intervention group (screening by abdominal ultrasonography) or control group. Participants with an abdominal aortic aneurysm > 5 cm were referred for surgical evaluation, and those with smaller aneurysms were offered annual scans. Outcome measures Specific mortality due to abdominal aortic aneurysm, overall mortality, and number of planned and emergency operations for abdominal aortic aneurysms. Results 4860 of 6333 men were screened (attendance rate 76.6%). 191 (4.0% of those screened) had abdominal aortic aneurysms. The mean follow-up time was 52 months. The screened group underwent 75% (95% confidence interval 51% to 91%) fewer emergency operations than the control group. Deaths due to abdominal aortic aneurysms occurred in nine patients in the screened group and 27 in the control group. The number needed to screen to save one life was 352. Specific mortality was significantly reduced by 67% (29% to 84%). Mortality due to non-abdominal aortic aneurysms was non-significantly reduced by 8%. The benefits of screening may increase with time. Conclusion Mass screening for abdominal aortic aneurysms in Danish men aged 65 or more reduces mortality.
Moderating Price Sensitivity of Low-Uncertainty Daily Eco-Friendly Products: Creating Benevolence Trust and Reducing Uncertainties

ABSTRACT For low-uncertainty daily eco-friendly products like eco-shampoo, consumers' willingness to pay a higher price can be the biggest barrier to hinder their purchase. In this research, we propose that benevolence trust does have a significant effect in mitigating this barrier. This research also shows that benevolence trust can reduce uncertainties and feelings of anxiety and increase feelings of optimism, symbolic benefits, and perceived price value while adopting daily eco-friendly products. Above all, the research findings show that further reduction of uncertainties plays a key role in driving consumers' willingness to pay a higher price when purchasing low-uncertainty daily eco-friendly products. The findings were also supported by a practical case study.
Study Of Digital Gap In Puerto Rico Business Sector Estudio De Brecha Digital En El Sector Empresarial De Puerto Rico

Information, communication technologies and the Internet have been transforming the way people work and do business. These technologies give companies the opportunities to gain instant access to international markets as well as improving performance in their domestic markets (Whitely, 2000). The recently emerging Internet services allows adoption of straightforward and cost-effective technologies straightforward that apply particularly to small businesses. These technologies transform their business model and enhance their competitiveness. However, research related to the subject confirms the small business sector is not adopting web technologies despite their potential benefits. The digital divide is the phenomenon of individuals or groups that differ from each other in the way they access or use information and communications technologies. Recently, most research about the digital divide in business context acknowledges that the small business sector presents has limited adoption of technologies. This research considers a more optimistic premise, where information and communication technologies and the Internet are key tools to boost small business development. The research is a descriptive study of digital divide indicators for the Puerto Rico business sector, complemented by a qualitative assessment and analysis of e-business service providers. Both study outcomes were guidelines for the theoretical technology adoption model proposed as a potential contribution to reducing the business digital divide
The Impact of the Legalization of Marijuana on Supply Chain Operations

The purpose of this thesis is to provide an analysis of key issues and considerations for a supply chain organization in regards to the impact of the legalization of marijuana on business operations. The main areas to be explored include legal considerations, the physical and cognitive effects of marijuana on an individual, the nature logistics functions and governmental regulations, and drug testing methods. Discussion on these issues will be based on current legislation and relevant research findings as well as on interviews with industry experts. Through this research it was determined that the best approach for companies evaluating their drug policies in response to the legalization of marijuana is to maintain and reinforce a zero-tolerance drug policy. Prohibiting marijuana use by employees is consistent with and protected under federal legislation and avoids many of the issues and complexities involved in the management and testing for marijuana use in employees. As research on marijuana use and development of improved testing methods continues to progress, companies may consider reevaluating their policies.
Wireless Input-Voltage-Sharing Control Strategy for Input-Series Output-Parallel (ISOP) System Based on Positive Output-Voltage Gradient Method

An input-series output-parallel (ISOP) system, in which multiple converter modules are connected in series at the input sides and parallel at the output side, is very suitable for high input-voltage, low output-voltage, and high output-current applications. Input-voltage sharing (IVS) and output-current sharing of the constituent modules among the ISOP system must be ensured. The existing IVS control strategies have drawbacks of lower reliability and lower modularity. In this paper, we propose a wireless IVS control strategy for ISOP systems based on positive output-voltage gradient method, which can effectively improve the reliability and modularity of ISOP systems. First, the operation principle of the proposed control strategy is introduced, and the IVS performance and output-voltage regulation characteristics of ISOP systems are analyzed. The stability of the proposed control strategy is also explored. A three-module ISOP system prototype is fabricated and tested in the laboratory, and the experimental results verify the effectiveness of the proposed control strategy.
The psychosocial effect of Tai Chi on nursing home residents.

AIM To determine the psychosocial effect of Tai Chi on nursing home residents. BACKGROUND Moving into a nursing home usually imposes a certain degree of psychosocial challenge to older people. However, there is limited evidence suggesting a promising intervention that can promote the psychosocial health for this group. Although previous studies suggest that Tai Chi has the potential to enhance psychosocial well-being, existing evidence is deemed scarce and thus imposes a limitation on drawing out conclusions on this matter. DESIGN Non-equivalent pretest-posttest control group design. METHODS A convenience sample of 139 residents from six nursing homes in Hong Kong was recruited for this study. The experimental group (n = 66) participated in a 26-week Tai Chi programme, while the control group (n = 73) continued its normal daily activities. The outcome measures included state self-esteem, the physical and mental component of health-related quality of life, social support network and social support satisfaction. Resident satisfaction was identified as a covariate because it demonstrated significant correlation with the outcome variables and, likewise, showed significant difference between the two study groups at baseline. Doubly multivariate analysis of covariance was performed to examine the effect of the intervention. RESULTS Results indicate significant Group x Time interactions, with the experimental group experiencing significant improvement in the composite outcome of state self-esteem, the physical component of health-related quality of life and the mental component of health-related quality of life across the 26-week study period [F(6, 131) = 2.61, p = 0.02)]. No significant changes were detected regarding the effect of the Tai Chi programme on social support. CONCLUSION Tai Chi practice is beneficial for nursing home residents. RELEVANCE TO CLINICAL PRACTICE Tai Chi has unique characteristics that are particularly suitable in the practice of health exercise for nursing home residents. The inclusion of Tai Chi in residential care practice for older people is recommended.
The Labrador Sea Deep Convection Experiment data collection

Between 1996 and 1998, a concerted effort was made to study the deep open ocean convection in the Labrador Sea. Both in situ observations and numerical models were employed with close collaboration between the researchers in the fields of physical oceanography, boundary layer meteorology, and climate. A multitude of different methods were used to observe the state of ocean and atmosphere and determine the exchange between them over the experiment's period. The Labrador Sea Deep Convection Experiment data collection aims to assemble the observational data sets in order to facilitate the exchange and collaboration between the various projects and new projects for an overall synthesis. A common file format and a browsable inventory have been used so as to simplify the access to the data.
Detection of incorrect pointer dereferences for C/C++ programs using static code analysis and logical inference

This article considers a method for an increase of static code analysis precision. The method extends classic code analysis algorithm with dependency analysis. For this purpose, during abstract interpretation information about statically known values should be extracted as well as dependencies between unknown values. Dependencies can be represented with first-order logic predicates. Such a method allows using of external logical inference tools to prove truth or falsehood of branch conditions and of error occurrence conditions. The main focus is oriented to pointer analysis logic and incorrect dereference detection rules. A prototype is implemented and results of efficiency evaluation are provided. The prototype uses Microsoft Z3 Solver as a logical inference tool. A significant precision increase is shown, ways for performance boosting are suggested.
Balance between cardiac output and sympathetic nerve activity in resting humans: role in arterial pressure regulation

Large, reproducible interindividual differences exist in resting sympathetic nerve activity among normotensive humans with similar arterial pressures, resulting in a lack of correlation between muscle sympathetic nerve activity (MSNA) and arterial pressure among individuals. Although it is known that the arterial pressure is the main short‐term determinant of MSNA in humans via the arterial baroreflex, the lack of correlation among individuals suggests that the level of arterial pressure is not the only important input in regulation of MSNA in humans. We studied the relationship between cardiac output (CO) and baroreflex control of sympathetic activity by measuring MSNA (peroneal microneurography), arterial pressure (arterial catheter), CO (acetylene uptake technique) and heart rate (HR; electrocardiogram) in 17 healthy young men during 20 min of supine rest. Across individuals, MSNA did not correlate with mean or diastolic blood pressure (r < 0.01 for both), but displayed a significant negative correlation with CO (r=−0.71, P= 0.001). To assess whether CO is related to arterial baroreflex control of MSNA, we constructed a baroreflex threshold diagram for each individual by plotting the percentage occurrence of a sympathetic burst against diastolic pressure. The mid‐point of the diagram (T50) at which 50% of cardiac cycles are associated with bursts, was inversely related to CO (r=−0.75, P < 0.001) and stroke volume (SV) (r=−0.57, P= 0.015). We conclude that dynamic inputs from CO and SV are important in regulation of baroreflex control of MSNA in healthy, normotensive humans. This results in a balance between CO and sympathetically mediated vasoconstriction that may contribute importantly to normal regulation of arterial pressure in humans.
