IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control | Year: 2017
Ultrasound shear wave elastography is emerging as an important imaging modality for evaluating tissue material properties. In its practice, some systematic biases have been associated with ultrasound frequencies, focal depths and configuration, and transducer types (linear versus curvilinear), along with displacement estimation and shear wave speed estimation algorithms. Added to that, soft tissues are not purely elastic, so shear waves will travel at different speeds depending on their spectral content, which can be modulated by the acoustic radiation force (ARF) excitation focusing, duration, and the frequency-dependent stiffness of the tissue. To understand how these different acquisition and material property parameters may affect the measurements of shear wave velocity, the simulations of the propagation of shear waves generated by ARF excitations in viscoelastic media are a very important tool. This paper serves to provide an in-depth description of how these simulations are performed. The general scheme is broken into three components: 1) simulation of the 3-D ARF push beam; 2) applying that force distribution to a finite-element model; and 3) extraction of the motion data for post-processing. All three components will be described in detail and combined to create a simulation platform that is powerful for developing and testing algorithms for academic and industrial researchers involved in making quantitative shear-wave-based measurements of tissue material properties. © 1986-2012 IEEE.

Tribune owns or operates 42 television stations in 33 markets, cable network WGN America, digital multicast network Antenna TV, minority stakes in the TV Food Network and CareerBuilder, and a variety of real estate assets. Tribune's stations, a list of which is available in Tribune's most recent Form 10-K filed on March 1, 2017, consist of 14 FOX, 12 CW, 6 CBS, 3 ABC, 2 NBC, 3 MyNetworkTV affiliates and 2 independent stations. The group includes stations in the top three DMAs in the country, seven in the top 10 and 34 in the top 50 DMAs.1 "This is a transformational acquisition for Sinclair that will open up a myriad of opportunities for the company," commented Chris Ripley, President and CEO of Sinclair. "The Tribune stations are highly complementary to Sinclair's existing footprint and will create a leading nationwide media platform that includes our country's largest markets. The acquisition will enable Sinclair to build ATSC 3.0 (Next Generation Broadcast Platform) advanced services, scale emerging networks and national sales, and integrate content verticals. The acquisition will also create substantial synergistic value through operating efficiencies, revenue streams, programming strategies and digital platforms." "This will be the largest acquisition in our company's history, and I want to thank everyone from the Sinclair team, as well as our advisors and bankers who made this possible," commented David Smith, Executive Chairman of Sinclair. "Television broadcasting is even more relevant today, especially when it comes to serving our local communities. Tribune's stations allow Sinclair to strengthen our commitment to serving local communities and to advance the Next Generation Broadcast Platform. This acquisition will be a turning point for Sinclair, allowing us to better serve our viewers and advertisers while creating value for our shareholders." "Today's announcement is the culmination of an extensive strategic review, which has delivered significant value to our stockholders," said Peter Kern, Tribune's Chief Executive Officer. "Since we announced the strategic review 15 months ago, we have streamlined the business, monetized non-core assets, strengthened our balance sheet and returned more than $800 million to stockholders -- all of which has resulted in a 50% increase in stockholder value. We are extremely proud to join Sinclair, and we're excited that Tribune stockholders and employees will have the opportunity to participate in the long-term growth of the combined company." The transaction has been unanimously approved by the Boards of Directors of both companies and is anticipated to close and fund in the fourth quarter of 2017. Completion of the transaction is subject to approval by Tribune's stockholders, as well as customary closing conditions, including approval by the Federal Communications Commission ("FCC"), and antitrust clearance. Sinclair expects to fund the purchase price at closing through a combination of cash on hand, fully committed debt financing to be provided by JPMorgan Chase Bank, N.A., Royal Bank of Canada, Deutsche Bank AG New York Branch and Deutsche Bank Securities Inc. and by accessing the capital markets. In order to comply with FCC ownership requirements and antitrust regulations, Sinclair may sell certain stations in markets where it currently owns stations. Such divestitures will be determined through the regulatory approval process. Including the Tribune acquisition (before any related divestitures), all previously announced pending transactions, and pro forma for expected synergies, Sinclair's 2015 and 2016 media revenues would have been $4.070 billion and $4.603 billion, respectively. The $6.6 billion enterprise value represents an average pro forma EBITDA multiple of less than 7.0x on the core television and entertainment business and is expected to add over 40% pro forma 2016/2017 free cash flow per share accretion2.

Background We sought to measure the impact of the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST) findings on clinical practice by studying trends in carotid artery stenting (CAS) and carotid endarterectomy (CEA) utilization before and after publication of CREST in a large US multihospital database. Methods The Premier Perspective Database was used to identify inpatient CEA and CAS procedures performed from January 2006 to March 2013. Patients were subclassified by age (<70/â‰¥70 years) and presentation (symptomatic/asymptomatic). CEA and CAS volumes were compared before and after the publication of CREST (July 2010) using an interrupted time series model. Results A total of 121,157 CEA and 18,503 CAS procedures performed at 445 medical centers were identified. There was no significant change observed in the overall number of CEA procedures performed after CREST publication relative to the pre-existing trend (P =.08); however, there was a significant increase in the overall number of CAS procedures performed (delta of 40 cases, P =.0179) in patients aged younger than 70 years (delta of 24 cases, P =.0008), 70 years or older (delta of 25 cases, P =.0047), and asymptomatic patients (delta of 39 cases, P =.0159). The overall percentage of CEA procedures performed in relation to all revascularization procedures was significantly lower after CREST publication overall (delta, -1.5%; P =.041) for patients aged younger than 70 years (delta, -2.4%; P <.0001) and asymptomatic patients (delta, -1.5%; P =.035). Conclusions In this large sample of US hospitals, performance of CAS significantly increased after the publication of the CREST study. © 2015 National Stroke Association.

This paper examines the influence of competition among supply chain partners on product demand. A power law demand function that depends on product pricing and shelf-space allocation (SSA) is used. The exponents in the power law are given by the elasticities of demand. In order to achieve the optimal pricing and SSA strategies in the presence of competition, game-theory-based methodologies-Cournot and Stackelberg games-are employed. For each type of game, a Nash equilibrium is achieved by optimizing the profit as a function of demand and price. A case study is presented to demonstrate the potential of this methodology. The results of this study indicate (1) how to achieve optimal pricing and SSA strategies, (2) how manufacturers can influence demand for a product, (3) that both prices and profits decrease using the Stackelberg game as compared with the Cournot game, and (4) that coordination beyond simple knowledge of price would be beneficial for improving overall profits. © 2013 Springer-Verlag London.

Web surveys are being increasingly incorporated into national survey data collection programs in the United States because of their cost/time-efficiencies. Yet, response rates and data quality issues in web surveys remain important challenges. As a basic study designed to better understand data quality in a mixed mode national survey, this article investigates the degree to which web versus mail survey modes affect unit and item responses. Findings indicate that the web survey mode produces a lower unit response rate compared to the mail mode. However, the web mode elicits higher data quality in terms of item responses to both closed- and open-ended questions. These mode effects on data quality remain after sociodemographic variables are held constant. Given the increasing integration of web survey questionnaires into mixed mode studies, additional research is necessary to understand and document the processes that underlie mode differences when responding to self-administered surveys. © The Author(s) 2012.

Interventions to improve health outcomes among patients with diabetes, especially racial or ethnic minorities, must address the multiple factors that make this disease so pernicious. We describe an intervention on the South Side of Chicago-a largely lowincome, African American community-that integrates the strengths of health systems, patients, and communities to reduce disparities in diabetes care and outcomes. We report preliminary findings, such as improved diabetes care and diabetes control, and we discuss lessons learned to date. Our initiative neatly aligns with, and can inform the implementation of, the accountable care organization-a delivery system reform in which groups of providers take responsibility for improving the health of a defined population. © 2011 Project HOPE-The People-to-People Health Foundation, Inc.

Asking respondents to record their activity in a diary can be a difficult task due to retrospective reporting and cognitive burden as well as the complexity of the data collection tool. Diary questionnaires typically require multiple pieces of information including demographics, activities, and duration over a data collection period. Like other questionnaire types, visual design principles can be used to help people perceive and understand what is being asked of them during diary measurement. Eye tracking, a technology that allows us to passively study people's eye movements, has been used mostly for questionnaire testing within the survey research field. This study focuses on using eye tracking and other user experience measures to analyze how respondents perceive, understand and experience different designs of the paper Nielsen TV Diary. We used eye tracking to gain insights into visual elements that draw attention, the amount of text that respondents read (e.g., terms/instructions), and how respondents complete the survey. This paper centers on the collecting and analyzing of qualitative and quantitative measures of the user experience, including eye-tracking data (e.g., fixation count, time to fixate), participants' verbalizations, self-reported satisfaction, and performance data (e.g., accuracy, steps to complete). We also provide recommendations about the design of the paper diary based on the user experience and eye-tracking results. © 2014 Springer International Publishing.

Using household scanner data and a discrete choice modeling approach, we estimate demand for milk products at the micro-level and compute the distribution of welfare effects from introducing organic milk across households with different characteristics within the partial equilibrium framework. The price effects of introducing organic milk are larger for low-income households than for high-income households, and the differences in the variety effects of introducing organic milk to groups with various levels of education are larger than the differences in the variety effects among groups with different income levels. Policy implications of these findings are discussed. © The Author (2013). Published by Oxford University Press on behalf of the Agricultural and Applied Economics Association. All rights reserved.

IMPORTANCE: For the past decade, more attention and concern has been directed toward financial relationships between the life science industry and physicians. Relationships between industry and institutional review board (IRB) members represent an important subclass that has the potential to broadly influence decisions regarding medical research. OBJECTIVES: To study the nature, extent, and perceived consequences of industry relationships among IRB members in academic health centers and to compare our results with findings from 2005. DESIGN, SETTING, AND PARTICIPANTS: A survey mailed to IRB members from the 115 most research-intensive medical schools and teaching hospitals in the United States from January 16 through May 16, 2014. The survey included questions identical to those used in 2005. Data analysis was conducted from June through October 2014. MAIN OUTCOMES AND MEASURES: The frequency of industry relationships among IRB members and the perceived effect of those relationships on IRB-related activities. RESULTS: We found no significant change inthe percentage of IRB members withan industry relationship from 2005 through 2014 (2005:37.2%; 95% CI, 32.7%-42.0%; 2014:32.1%; 95% CI, 28.0%-36.4%; P =.09). However, since 2005, the percentageof members who felt another member did not properly disclose a financial relationship decreased from 10.8% (95% CI, 8.0%-14.4%) to 6.7% (95% CI, 4.7%-9.4%) (P =.04), asdid the percentage who felt pressure from their institution or department to approve a protocol (2005:18.6%; 95% CI, 15. 0%-22.9%; 2014:10.0%; 95% CI, 7.6%-13.0%; P <.001). The percentage of members with a conflict of interest who voted on protocols with which they have a conflict has not changed, although the percentage who said they always disclose relationships increased significantly from 54.9% in 2005 (95% CI, 42.2%-66.9%) to80.0%in 2014 (95% CI, 65.3%-89.4%) (P =.01). We also found evidence of anti-industry bias in the presentation of protocols to the IRB. CONCLUSIONS AND RELEVANCE: The results show significant positive progress in the reporting and management ofconflicts of interest among IRB membersin academic health centers since 2005 after adjusting for other factors. Additional attention should be focused on deterring IRB members from inappropriately voting on or presenting protocols in a biased manner. Copyright 2015 American Medical Association.
