OBJECTIVE: The increasing capabilities of camera-equipped mobile phones have led to a growing body of evidence regarding their use in medical imaging across a broad range of medical specialties. This article reviews the current evidence for the use of mobile health (m-health) in medical imaging.MATERIALS AND METHODS: We performed a structured review of the published literature regarding m-health in medical imaging using the Medline, PubMed, and Web of Science databases (January 2002-August 2013). The two authors independently extracted data regarding type of specialty, purpose, and study design of publications.RESULTS: In total, 235 articles were identified. The majority of studies were case reports or noncomparative product validation studies. The greatest volume of publications originated in the fields of radiology (21%), dermatology (15%), laboratory techniques (15%), and plastic surgery (12%). Among these studies, m-health was used as diagnostic aids, for patient monitoring, and to improve communication between health practitioners. With the growing use of mobile phones for medical imaging, considerations need to be given to informed consent, privacy, image storage and transfer, and guidelines for healthcare workers and patients.CONCLUSIONS: There are several novel uses of mobile devices for medical imaging that show promise across a variety of areas and subspecialties of healthcare. Currently, studies are mostly exploratory in nature. To validate these devices, studies with higher methodological rigor are required.

The ASM International Board of Trustees announces the appointment of William T. (Bill) Mahoney as Managing Director effective immediately. The appointment follows an extensive search led by the Board-appointed Executive Search Committee with the assistance of Dise & Co. Mahoney's appointment is effective immediately. Mahoney is formerly the CEO of the South Carolina Research Authority (SCRA). He held this post from August 2005 to March 2016. SCRA is a non-stock, tax-exempt applied R&D corporation, which operates under a public charter from the state of South Carolina, but is economically self-sufficient due to its business operations, and receives no state funding. Under Mahoney's leadership, SCRA annual revenues from its applied research and commercialization services operations have grown from $74M to over $455M. In this same timeframe, SCRA annual year-end backlog grew from $93M to $1091M, annual net revenues have set company records of up to 7.9%, and total contract value under management grew from $235M to over $5.2B. SCRA's financial growth has paralleled its advancing reputation within defense, security, advanced materials, and energy and sustainability market segments as a dynamic, research-based business, uniquely able to rapidly and cost-effectively apply innovative technologies to important government and corporate problem sets. In its vertical markets, SCRA today competes effectively against established entities such as Battelle, SAIC, IBM, CTC, Mitre Corp, and others. Mahoney holds a TS clearance, which was a condition of employment at SCRA. During his tenure, SCRA received national and international best practices recognition from the defense industry for its Navy Centers of Excellence, and from the State Science and Technology Institute, Southern Growth Policies Conference, International Economic Development Council, Entrepreneur Magazine, and Forbes Magazine for its SC Launch seed capital and support services programs. In 2008, Mahoney was named by Tech Journal South magazine as one of the top 25 technology leaders in the southeastern United States. In 2010, SCRA's Applied R&D Sector was chosen by The Wall Street Journal as one of America's Top 15 Winning Workplaces. SCRA was recognized as Non-Profit Corporation of the Year 2011 by the American Business Congress' "Stevie" Awards, and the same group chose Bill as Non-Profit Executive of the Year in 2012. Mahoney's peers from other industry segments in this 2012 Executive of the Year selection included Allen Mulally of Ford, and John Lundgren of Stanley Black and Decker. In 2013 and 2014, SCRA was awarded multiple "Stevie's" for national leadership in technology innovation and corporate responsibility programs. SCRA invests the net revenues of its applied R&D contracts to effect its public mission, which is the development of the knowledge economy in South Carolina. Since 2006, SCRA investment programs, including R&D infrastructure, startup equity investments, SBIR matches, grants, subcontracts, and sponsorships, have generated and deployed over $380M in cash into the SC knowledge economy. Over $100M of that investment has supported commercialization of university research and technologies. Private add-on investment of over $400M in equity capital has followed SCRA placements, and SCRA has supported or assisted over 700 SC Corporations, ranging from BMW down to over 320 early stage startups. All of these decade-long achievements have occurred without any annual state appropriations. During the roughly 30 years prior to coming to SCRA, Mahoney led companies small and large, which commercialized ″first-of-a-kind″ solutions in telecommunications, electronic publishing, automatic remote monitoring and other emerging applied systems markets, leading directly to IPO's or strategic acquisitions. Among these companies was SCT Utility Systems, of Columbia, SC. Between 1995 and 2000, SCT grew from startup to $175M annual revenues, prior to its sale to Indus International (now Ventyx Corp). SCT′s installed base of customer information systems for energy, utility, and communications companies is still one of the largest of its kind in the world. Mahoney held a non-voting seat as secretary of the SCRA Board, and also served as the chairman of SCRA's wholly-owned applied R&D affiliate, Advanced Technology International Inc. He currently serves on outside corporate boards as chairman of SCRA-invested tech startups STEM Premier and Carbon Conversions Inc. He also serves on national Boards with the National Defense Industrial Association, the National Energy Marketers Association and the Fuel Cell and Hydrogen Energy Association. On a state and local level, he serves or has served on the boards of the SC Hydrogen and Fuel Cell Alliance, Midland Technical College Foundation, and SC Economics. Mahoney is a Harvard graduate and former member of both the Harvard Crew and the U.S. National Rowing Team. He and his wife, Paula, have been married for 37 years and have two adult sons, one a U.S. Navy officer and one a professional baseball player.

The formation and structure of complete composite binary offset carrier (CBOC) modulated signals are analyzed as applied to the new-generation satellite radio navigation systems (SRNSs) (in particular, the European Galileo and, presumably, Chinese BeiDou/Compass systems). The block diagram of the CBOC-signal satellite transmitter based on the coherent adaptive subcarrier modulation (CASM) algorithm is discussed. Analytical expressions for the correlation functions (CFs) characterizing the single elements of the modulating function (MF) of CBOC signals are derived at arbitrary fractional coefficients. The CFs of the single elements of the MFs of CBOC signals are represented graphically and their properties are discussed. The Fourier transforms of CFs are used to calculate the energy spectra (power spectral densities) of the single elements of the MFs of CBOC signals. CF features and the energy spectra of CBOC signals are analyzed using signals with CBOC(6, 1, a2/11) modulation, which are typical of the European Galileo and Chinese BeiDou/Compass systems at the carrier frequency fcar = 1575.42 MHz and the fractional coefficient a2 = 1. © 2015, Pleiades Publishing, Inc.

It is demonstrated that, when the function describing the impedance distribution on a plane belongs to a certain class, a wave normally incident on the plane is diffusively scattered and absorbed rather than reflected. When the contour of a finite plane segment satisfies a certain condition, a wave is not reflected by this segment. Such plane figures can provide for antiradar protection. In particular, they can be made from a lossless material. © 2015, Pleiades Publishing, Inc.

Publications are a crucially important factor in our research. In recent months the traditional model of scholarly publishing has started to change with low-cost online publishing, open access and - most recently - data-sharing or open data. This keynote examines these changes and looks at the approaches that are being taken to optimise the new arrangements and some of the as yet unforeseen, and possibly undesirable, consequences. © 2013 Springer-Verlag.

The navigation signals with sine binary offset carrier (sinBOC), cosine BOC (cosBOC), and alternative BOC (AltBOC) modulations are discussed. A technique for calculating the correlation functions (CFs) of the single components of modulating functions (MFs) inherent to the given signals, which is based on the inverse Fourier transform (IFT) of energy spectra, is proposed. This technique makes it possible to derive analytical expressions for the CFs characterizing the single components of the MFs of sinBOC and cosBOC signals and complete AltBOC waveforms with a constant envelope at the multiplicity coefficients Nm = 2‒4. The graphs of CFs are constructed. Several illustrating examples, in which most attention is paid to sinBOC, cosBOC, and AltBOC signals employed in the Galileo satellite radio-navigation system and the global positioning system, are presented. © 2016, Pleiades Publishing, Inc.
