Current Use of Intravascular Ultrasound in Coronary Artery Disease

Recently, most coronary interventions rely on visual assessment of the coronary lesions using angiography with all known inherent limitations. Intravascular ultrasound (IVUS) allows for the evaluation of the coronary pathology to obtain information about both the extent and nature of atherosclerotic plaque; thus, planning the intervention strategy is based on objective data. Following the advent of gray-scale IVUS, several modes had been developed to study coronary plaque composition, thus determining the predominant component of the plaque, fibrous tissue, lipid-necrotic core, or calcium, and the intervention strategy. After intervention, IVUS plays an important role in optimizing the results after stent deployment regarding stent expansion and apposition to reduce the incidence of both stent thrombosis and in-stent restenosis. This review discusses the basic role of IVUS in evaluating plaque structure and parameters to optimize results after coronary intervention in light of recent evidence.
MIMO Identification of Power System With Low Level Probing Tests: Applicability Comparison of Subspace Methods

Dynamic modeling of a power system is fundamental to its safe operation and control. With the development of wide-area measurement system (WAMS) and low level probing tests, it is feasible to estimate a multiple-input multiple-output (MIMO) model of a power system without large disturbances. In practice, outputs during the low level probing tests consist of measurement noise, system noise and probing responses. Before applying a field experiment of MIMO modeling, noise influence to the system modeling as well as applicability of existed identification methods should be examined. In this paper, four kinds of subspace methods are carefully compared for their applicability in power systems' MIMO modeling with low level probing test. Results with different noise conditions explore the noise influence and the suitable methods for field experiment. Monte Carlo method is used for statistic analysis in a small system and conclusions are validated in a large complex system, China Southern Grid.
A framework of ERP system evaluation of project driven enterprise: a case study

Nowadays enterprise resource planning (ERP) systems are worldwide a standard solution implemented in a great number of manufacturing companies worldwide. The implementation of an ERP system is performed to integrate business processes, allocate company’s resources efficiently and provide important data for decision support. Implementing an ERP system is expensive and time-consuming. Therefore a great number of research activities are focused on key success factors of ERP implementations. But what does a successful implementation of ERP system mean? If an ERP project was completed according to the schedule, the budget was not exceeded and the scope was realized, it means that the implementation was successful? Implementation of an ERP system is a long-term undertaking, and not only a short-term project that is finished just after the system installation. Especially for a project driven enterprise that realizes engineer-to-order production, the evaluation should encompass a long period of time. In the article a methodology based on ERP data analysis and end users’ satisfaction is proposed. This research is based on a real data, extracted from ERP system of a polish company that realizes prototyping production in the area of machine tools construction.

Decreased epinephrine responses to hypoglycemia during sleep.

BACKGROUND In patients with type I diabetes mellitus, hypoglycemia occurs commonly during sleep and is frequently asymptomatic. This raises the question of whether sleep is associated with reduced counterregulatory-hormone responses to hypoglycemia. METHODS We studied the counterregulatory-hormone responses to insulin-induced hypoglycemia in eight adolescent patients with type I diabetes and six age-matched normal subjects when they were awake during the day, asleep at night, and awake at night. In each study, the plasma glucose concentration was stabilized for 60 minutes at approximately 100 mg per deciliter (5.6 mmol per liter) and then reduced to 50 mg per deciliter (2.8 mmol per liter) and maintained at that concentration for 40 minutes. Plasma free insulin, epinephrine, norepinephrine, cortisol, and growth hormone were measured frequently during each study. Sleep was monitored by polysomnography. RESULTS The plasma glucose and free insulin concentrations were similar in both groups during all studies. During the studies when the subjects were asleep, no one was awakened during the hypoglycemic phase, but during the final 30 minutes of the studies when the subjects were awake both the patients with diabetes and the normal subjects had symptoms of hypoglycemia. In the patients with diabetes, plasma epinephrine responses to hypoglycemia were blunted when they were asleep (mean [+/-SE] peak plasma epinephrine concentration, 70+/-14 pg per milliliter [382+/-76 pmol per liter]; P=0.3 for the comparison with base line), as compared with when they were awake during the day or night (238+/-39 pg per milliliter [1299+/-213 pmol per liter] P=0.004 for the comparison with base line, and 296+/-60 pg per milliliter [1616+/-327 pmol per liter], P=0.004, respectively). The patients' plasma norepinephrine responses were also reduced during sleep, whereas their plasma cortisol concentrations did not increase and their plasma growth hormone concentrations increased slightly. The patterns of counterregulatory-hormone responses in the normal subjects were similar. CONCLUSIONS Sleep impairs counterregulatory-hormone responses to hypoglycemia in patients with diabetes and normal subjects.
Obstacle distance detection system for sight-disabled people

In this study, an obstacle distance detection system is designed for sight-disabled people. This system finds distances between the obstacles and sight-disabled people and is alerted according to distance value. Images captured from two USB cameras are processed in MATLAB environment. The obstacle detection is performed in three phases. The system is calibrated in the first phase. With the implementation of calibration steps, intrinsic and extrinsic parameters of the cameras are calculated as a result of the calibration. Images are provided with the rectification of these parameters. The second phase is stereo matching step, the simultaneous images which are captured from the left and right cameras processes and disparity map is obtained in this phase. At this stage, points, are tried to be identified, where are the three dimensional points correspond to different image planes. Barriers, through the help of stereo disparity maps, are identified with discovery of the points that occurs consecutively and that have the same difference value. Then, with the help of identified difference value in the identified barrier area and geometrical location of the cameras, distance of barrier to the camera is calculated. In last phase, the sight-disabled individuals alerted with the microcontroller hardware.
Board's Monitoring and Retention of Sub-standard and Powerless CEOs

Do corporate boards look after shareholder interests? This paper shows that CEO replacement may exhibit excessive inertia, in favor of the incumbent board of directors. I show that even when there is no relationship between the board of directors and CEO, or no threat of the CEO.s power over the board of directors, there is a case in which the board wants to keep sub-standard CEOs.
Embolism from vertebral artery origin occlusive disease

We report 10 patients with severe occlusive disease of the vertebral artery (VA) origin in the neck with intra-arterial embolism to the posterior circulation. The VA lesions in seven patients were complete occlusions, and three patients had severe atherostenosis. All patients had strokes in the vertebrobasilar territory. The most frequent recipient sites of intra-arterial embolism were the intracranial VA-posterior inferior cerebellar artery region (8), and the distal basilar artery (BA) and its superior cerebellar and posterior cerebral artery branches (7). Two patients had pontine infarction due to BA embolism. The most common clinical signs were due to cerebellar infarction. Atherosclerotic disease of the VA origin has features in common with disease of the internal carotid artery origin. Both have similar risk factors and demography, and each can cause strokes by intracranial intra-arterial embolism.
Reconsidering the international monetary system

I am honored to have this opportunity to discuss prospects for strengthening the international monetary system. The topic is both timely and important. In many ways, the generally recognized sources of the recent global financial crisis involve factors that inevitably can be viewed—at least in part—as reflecting weaknesses in the existing international system. Moreover, many of the efforts under way to prevent future crises—especially those being pursued with the sponsorship and support of the G20 Leaders Summit process—are intended to enhance the resiliency and effectiveness of the international monetary system. In this context, it is sobering to recognize that the last comprehensive, broad-based discussions of international monetary reform were held nearly four decades ago.
Positioning for International Market Segments in Higher Education: Evidence from Saudi Arabia

The purpose of this qualitative research was to identify target segments to achieve objectives related to the recruitment of high performance international students and distinguished faculty in higher education sector of Saudi Arabia. Based on the premise that internal communicative branding activities are vital for educational institutions, the study examined facultyâ€™s perceptions of relevant positioning attributes for Saudi Arabia to compete in the global academic marketplace. Analysis of 92 facultyâ€™s responses helped to develop awareness of a perceived added value to occupy a niche in the higher education market. The findings highlighted distinctive positioning strengths to brand higher education institutions in Saudi Arabia. However, it can be implied that Universities should strategize their internal values rather than factors of the external environment to capitalize on these assets in the long run.
Accurate measurements of the acoustical physical constants of LiNbO/sub 3/ and LiTaO/sub 3/ single crystals

The acoustical physical constants (elastic constant, piezoelectric constant, dielectric constant, and density) of commercial surface acoustic wave (SAW)-grade LiNbO/sub 3/ and LiTaO/sub 3/ single crystals were determined by measuring the bulk acoustic wave velocities, dielectric constants, and densities of many plate specimens prepared from the ingots. The maximum probable error in each constant was examined by considering the dependence of each constant on the measured acoustic velocities. By comparing the measured values of longitudinal velocities that were not used to determine the constants with the calculated values using the previously mentioned constants, we found that the differences between the measured and calculated values were 1 m/s or less for both LiNbO/sub 3/ and LiTaO/sub 3/ crystals. These results suggest that the acoustical physical constants determined in this paper can give the values of bulk acoustic wave velocities with four significant digits.
Internet Banking in India: Challenges and Opportunities

Banking activities have been into existence since 18th century BC. The main purpose that banks have been serving since their inception is keeping our money safe for us. Traditional banks have been doing this, and internet banks continue the same function. The only difference is in the way the transactions are made. The Internet is rapidly turning out to be a tool of worldwide communication. The increasing use of Internet earlier promoted producers and entrepreneurs to sell their products online. It has also become an important source of information and knowledge. Due to this, many banking and finance organizations have come up with the idea of Internet banking or online banking. In this paper we have tried to study the Nature, challenges & opportunities of Internet Banking in India.
Finance-led capitalism? : macroeconomic effects of changes in the financial sector

During the recent decades the financial sectors of developed and developing countries have changed remarkably. There has been a major increase in the degree of financial intermediation, and new financial instruments, triggered by national and international legal liberalisation and by the development of communication technologies, have been developed. The overall importance of financial factors for real investment and growth of non-financial business has risen. Finally, the power of shareholders in joint stock companies seems to have increased vis-a-vis management and labourers. These and other changes as well as their effects on the macro-economy require deeper investigation, in particular since the US sub-prime mortgage crisis has been spreading over international financial markets and has already affected real development in the negative.
A linearized current stimulator for deep brain stimulation

This paper develops the front end of the stimulator which is applied in the implantable deep brain stimulation (DBS) for the therapy of Parkinson's disease. This stimulator adopts the low power switched-capacitor DAC accompanying with voltage-to-current transconductance amplifiers to obtain the adjustable output currents. The proposed distortion cancellation technique improves the linearity of the current stimulator. Multiple transconductance amplifiers sharing a single DAC save the circuit area. The biphasic stimulation waveform is generated from the bridge switching technique and the programmable pulse. This stimulation circuit provides the 0∼165 µA current for a typical loading of 10 kΩ, 8∼120 µs pulse width, and 126∼244 Hz frequencies with a 0.35 µm CMOS technology at 3.3 V supply voltage.
AN EVOLUTIONARY EXAMINATION OF THE FLORAL DISPLAY of CATALPA SPECIOSA (BIGNONIACEAE)

Those plant species that rely on animals to mediate the transfer of pollen usually attract pollinators with visual and/or aromatic stimuli and then reward them with pollen, nectar, or some other food (Faegri and van der Pijl, 1971; Proctor and Yeo, 1973). Under some circumstances (i.e., competition for pollinators) there may be selective pressures to increase the size of the attractants and rewards in order to secure more visits by the pollinators. One possible response of a plant to these pressures is to cluster flowers in time and space. This would make the plant more conspicuous to pollinators and it would also increase the pollinator's reward by decreasing the search time and distance between food sources (see Burtt, 1961; Janzen, 197 la; Heinrich and Raven, 1972; Gentry, 1974; Willson and Rathcke, 1974; Heinrich, 1975). There are many plant species that regularly produce inflorescences consisting of many flowers but initiate only a few fruits. Species with this flowering and fruiting pattern include Albizia lebbeck (Maheshwari, 1931), Aesculus spp. (Percival, 1965; Benseler, 1975), Cassia grandis (Janzen, 197 la), Eucalyptus spp. (Carr et al., 1971), various orchard trees (see Kozlowski, 1973), Asclepias spp. (Willson and Rathcke, 1974; Wilbur, 1976; Willson and Price, 1977) and Catalpa spp. (Stephenson, 1978). Because each flower on these species has a low probability of setting fruit, there is the possibility that inflorescence size has been selected for factors other than a flower's ability to set fruit (see Willson and Price, 1977). In this study, I use Catalpa speciosa (Warder ex Barney) Engelm. (Bignoniaceae) to test which of three alternative hypotheses explains the proximate factors involved in a high ratio of flowers to fruits and then to test several ultimate factors that infer the adaptive significance of this pattern.
Towards decision support for disclosing data: Closed or open data?

The disclosure of open government data is a complex activity that may create public value yet might also encounter risks, such as the misinterpretation and misuse of data. While politicians support data release and assume that the positive value of open data will dominate, many governmental organizations are reluctant to open their data, as they are afraid of the dark side. The objective of this paper is to provide a decision-making model that assists in trade-offs between the pros and cons of open data. Data disclosure is dependent on the type of data (e.g. its sensitivity, structure and quality) and the context (e.g. organizational policies, legislation and the political influences). Based on the literature and fifteen in-depth interviews with public sector officials and data archivists, this paper identifies contextual and dataset-related variables which influence a trade- off. A decision-making model is presented capturing trade-offs, and in this way providing guidance for weighing the creation of public value and the risks. The model can be used for decision-making to open or not to open data. It is likely that the decision regarding which data should be opened or closed will shift over time.
Real-time and low cost energy disaggregation of coarse meter data

A novel real-time non-intrusive appliance load monitoring algorithm is introduced. By applying finite state machine training, dynamic appliance disaggregation, rule-based filtering and discrete Fourier analysis of coarse data, several improvements are achieved: 1) reduced appliance model training complexity as compared to existing algorithms, and 2) novel and augmented detection stage. The application of this algorithm on real world data demonstrates that efficiency does not have to be compromised by the relatively lower complexity.
Effective Infrastructure Management Solutions Using the Analytic Hierarchy Process and Municipal DataWorks (MDW)

The economic success of a nation, province, or municipality is closely tied to the condition of their civil infrastructure. Ontario roads and bridges built throughout the 1950s and 60s are quickly approaching the end of their design life. Without the necessary funding, the declining condition of these assets can result in roads with compromised safety and increased road user cost. Historically, there has been an underinvestment in maintaining our infrastructure at an acceptable level. Small municipalities are the most seriously affected by this underinvestment and are continually placed in a position where they are required to do more with less. In 2008, the Ontario provincial government, the Association of Municipalities of Ontario (AMO), and the City of Toronto published the Provincial-Municipal Fiscal and Service Delivery Review that identified a $60 billion investment was required over 10 years to bring our aging physical structures and facilities back to an acceptable standard. Of this amount, $28 billion would need to be dedicated to upgrading Ontario's roads and bridges. The paper focuses on how small municipalities can effectively manage and improve the condition of their aging road infrastructure based on several funding scenarios. To achieve this, best practices in the area of infrastructure management and capital investment planning will be explored using the Ontario Good Roads Association's asset management software, Municipal DataWorks (MDW).

Factors Affecting the Usage of Major Heuristics in Nigeria Property Investment Valuation

Heuristics property research has been confined to Anchoring and Adjustment at the neglect of the other three major ones, which are, availability, representative and positivity. Even when researches in anchoring and adjustment heuristics are conducted they are usually confined to its existence. This study examined factors affecting the usage of heuristics from variables drawn and conceptualized from literature review (models). This is geared towards focusing heuristics property research particularly in this country. This study is a cross- sectional research entailing a survey of 159 out of the 270 Head Offices of Estate Surveying Firms in Lagos Metropolis, the entire 29 and 30 Head Offices of Estate Surveying Firms in Abuja and Port-Harcourt respectively. The primary source of data collection was through the questionnaire in the form of conducting interview. The data collected was measured using ordinal scales and analysed using categorical regression analysis on the SPSS Software. The zero- order correlation was used as a measure of variable importance being independent of the other predictors in the model. It was observed that the most predominant factors affecting the usage of Anchoring and adjustment; Availability; Representative and Positivity Heuristics are complexity of investment method of valuation (-.234; .462) and age of the estate surveying and valuation firm (-.339; -.297) respectively. The study thereby reveals areas of principal focus in heuristics property research so as to avoid superfluity.
