description: Physicians' use of handheld computers is increasing, but still incomplete.  Device usability is a commonly cited adoption barrier. This study explores  physicians' usability evaluations and adoption preferences for handheld computers.  We conducted a randomized crossover study to compare the Apple iPod Touch and  Palm Tungsten C. The study was conducted in a laboratory setting with 23 internal  medicine resident physicians from Duke Medical Center. Participants used each  device to respond to clinical questions based on hypothetical cases and completed a  survey based on the extended Technology Acceptance Model. The iPod Touch had  significantly higher ratings than the Tungsten C for perceived ease of use, perceived  usefulness, subjective norm, image, and intention to use. Perceived ease of use was  an important determinant of participants' intention to use handheld computers.  Improving ease of use may encourage handheld computer adoption among  physicians.

description: Supermassive black holes (BHs) of millions solar masses and above reside in the center of most local galaxies, but they also power active galactic nuclei and quasars, detected up to z=7. This observational evidence puts strong constraints on the BH growth and the mass of the first BH seeds. The scenario of "direct collapse" is very appealing as it leads to the formation of large mass BH seeds in the range 10^4-10^6 Msun, which eases explaining how quasars at z=6-7 are powered by BHs with masses >10^9 Msun. Direct collapse, however, appears to be rare, as the conditions required by the scenario are that gas is metal-free, the presence of a strong photo-dissociating Lyman-Werner flux, and large inflows of gas at the center of the halo, sustained for 10-100 Myr. We performed several cosmological hydrodynamical simulations that cover a large range of box sizes and resolutions, thus allowing us to understand the impact of several physical processes on the distribution of direct collapse BHs. We identify halos where direct collapse can happen, and derive the number density of BHs. We also investigate the discrepancies between hydrodynamical simulations, direct or post-processed, and semi-analytical studies. We find that for direct collapse to account for BHs in normal galaxies, the critical Lyman-Werner flux required for direct collapse must be much less than predicted by 3D simulations that include detailed chemical models. However, when supernova feedback is relatively weak, enough direct collapse BHs to explain z=6-7 quasars can be obtained for more realistic values of the critical Lyman Werner flux.

description: Wir untersuchen Pfadplanungsprobleme aus der Robotik und die Berechnung von Stra- tegien, die beweisbare Garantien für Sicherheitseigenschaften liefern. Dabei soll ein Agent mit hoher Wahrscheinlichkeit einen Zielort erreichen, ohne mit einem Hindernis zusammenzustoßen, das sich probabilistisch durch den Raum bewegt. Schwierig wird dieses Problem dadurch, dass der Agent seine Umgebung nur eingeschränkt beobachten kann. Dieses Szenario lässt sich auf na- türliche Art und Weise als ein sogenannter partiell beobachtbarer Markow-Entscheidungsprozess (POMDP) modellieren. Da viele interessante Eigenschaften auf POMDPs unentscheidbar sind, beschäftigt sich die hier vorgestellte Arbeit mit der Entwicklung einer spielbasierten Abstraktionsmethode, um für solche Pfadplanungsprobleme und Sicherheitseigenschaften gute Approximationen zu berechnen.

description: Despite increasing efforts to engage girls in STEM, a STEM gender gap still exists. One possible reason for this is the persistent masculine/unattractive stereotype of women engaged in STEM fields. This study examined twelve young adult novels featuring female protagonists who display STEM interests in an effort to determine how the protagonists are portrayed as both STEM actors and teenage girls. The results showed that the protagonists were mostly represented as well-supported, well-rounded, and successful at meeting their STEM goals. They were, however, shown to possess more masculine traits than feminine traits. The books studied were ultimately recommended for use as a tool to interest adolescent girls in engaging with STEM fields.
Towards Automated Refinement of TLM Properties to RTL

description: In the recent years, the emergence of the Electronic System Level (ESL) can be witnessed. An ESL design flow starts with a TLM description, which is thoroughly verified and then refined to a RTL description in subsequent steps. Obviously, the correctness of TLM models is of great importance, as undetected errors will propagate and become very costly. In the past few years, a wide body of verification techniques at TLM has been developed ranging from simulation- based to formal verification, which typically employs property checking. The subsequent verification of the RTL model is commonly performed by a TLM/RTL co-simulation, where the same input stimuli are applied to both models and their outputs are checked for equivalence. This step requires an additional executable verification component, known as transactor, to bridge the function calls at TLM with the signal-based interfaces at RTL and vice versa. Due to incompleteness, it is highly desirable that co-simulation is complemented with other (preferably formal) approaches. A promising direction is to reuse properties that have been proven on the TLM model. However, semantic differences of the involved abstraction levels prevent straight-forward reuse. The translation process, i.e. TLM-to-RTL property refinement, is mostly manual, therefore error-prone and time-consuming. To the best of our knowledge, we propose in this paper the first fully automated TLM-to- RTL property refinement approach [1]. The main idea lies in a better reuse of the readily available transactors. At the core of our approach is a static transactor analysis based on symbolic execution. Essentially, the analysis reverse-engineers the executable transactors to create a formal specification of the underlying protocol as Finite State Machines (FSM). Starting with the initial symbolic execution state, the transactor function is repeatedly executed, until all reachable states are explored. This symbolic state space is transformed into an FSM by abstracting away all data except the RTL signal values. Then, TLM properties are refined by relating high-level TLM events with RTL signal combinations at different clock cycles based on the FSM. As a feasibility study we applied our refinement approach on a realistic case study of an ATM receiver device with two representative TLM properties. We believe that the proposed approach is of great practical interest. For future work we plan to define a formal characterization of supported properties.

description: We study an undirected polymer chain living on the 1-dimensional integer lattice and carrying i.i.d.\ random charges. Each self-intersection of the polymer contributes to the Hamiltonian an energy that is equal to the product of the charges of the two monomers that meet. The joint law for the polymer chain and the charges is given by the Gibbs distribution associated with the Hamiltonian. The focus is on the \emph{annealed free energy} per monomer in the limit as polymer length diverges. We derive a \emph{spectral representation} for the free energy and we exhibit a critical curve in the parameter plane of charge bias versus inverse temperature separating a \emph{ballistic phase} from a \emph{subballistic phase}. The phase transition is \emph{first order}. We prove large deviation principles for the laws of the empirical speed and the empirical charge, and derive a spectral representation for the associated rate functions. Interestingly, in both phases both rate functions exhibit \emph{flat pieces}, which correspond to an inhomogeneous strategy for the polymer to realise a large deviation. The large deviation principles lead to laws of large numbers and central limit theorems. We identify the scaling behavior of the critical curve for small and large charge bias and also the scaling behavior of the free energy for small charge bias and small inverse temperature. Both are linked to an associated \emph{Sturm-Liouville eigenvalue problem}. A key tool in our analysis is the Ray-Knight formula for the local times of 1-dimensional simple random walk. It is used to derive a \emph{closed form expression} for the generating function of the annealed partition function and to derive the spectral representation for the free energy. What happens for the \emph{quenched free energy} remains open. We state two modest results and raise a few questions.

description: Underwater communication with autonomous underwater vehicles (AUVs) has strong demands on the modems caused by the constantly changing signal propagation (multipath propagation, scattering, diffraction and refraction at thermal layers, etc.) of the underwater channel. These demands typically lead to a modem designed to match specific conditions. This results in two major problems, first we do not want to develop for each changing environment a specific hardware and second we need a robust communication to distribute necessary information about the state of the system, current condition of the environment or to coordinate group missions. In this paper we introduced a approach to serve booth of the problems. We implemented with a flexible generic design a robust underwater communication system. The paper introduce a designed approach for a generic reusable acoustic underwater communication based on a pipelined data stream processing system on a Field Programmable Gate Array (FPGA). Exploiting the inherent synchronization mechanism of an hand-shake-based streaming bus interface to form arbitrary long pipelines composed of detached and reusable modules representing the coding and modulation algorithms without the need of an external coordination mechanism. We show that our approach is feasible, matches the problems and can easily be changed or extended to a Multiple Input Multiple Output (MIMO)-system while the recommendation on energy consumption is nearly equally and area is reduced by 45% compared to other system implementation.

description: Pressure-sensitive adhesives based on silicone materials have emerging potential as adhesives in healthcare products, in particular for gentle skin adhesives. To this end, adhesion to rough skin and biocompatibility are crucial factors for a successful implementation. In this study, the mechanical, adhesive, and biological properties of the two-component poly(dimethylsiloxane) Soft Skin Adhesive MG 7-9800 (SSA, Dow Corning) have been investigated and compared to Sylgard 184. Different mixing ratios of SSA's components allow for tuning of the shear modulus, thereby modifying the adhesive properties of the polymer. To give a comprehensive insight, the authors have analyzed the interplay between pull-off stress, adhesion energy, and stretch of the adhesive films on smooth and rough surfaces. The focus is placed on the effects of substrate roughness and on low pressure oxygen plasma treatment of the adhesive films. SSA shows superior biocompatibility in in vitro cell culture experiments. High pull-off stresses in the range of 3 N cm−2 on a rough surface are achieved, promising broad application spectra for SSA-based healthcare products.

description: Design Space Exploration (DSE) for embedded system design with its multi-objective nature and large search spaces typically prohibits exhaustive search and popularized the use of metaheuristic optimization techniques. Recent large-scale multi- and especially many-core architectures offering a multitude of application mapping possibilities create tremendously large search spaces which give rise to the question whether established metaheuristics are still efficient. In this work, we propose to employ a heuristic search-space restriction (SSR) approach based on the exploration of subsystems, which significantly reduces individual search-space size and, thus, exploration time. Knowing that this kind of restriction may miss global optima, we also investigate the use of high-quality solutions derived from subsystems as an initial population for the optimization of the complete system. Experimental results for tiled 8x8 to 24x24 many-core architectures and several benchmark applications show that the proposed SSR enables the metaheuristic to derive implementations of higher quality in a significantly reduced exploration time. Although not all global optima are exposed to the restricted problem, this work gives evidence that too complex search spaces may sacrifice the efficiency of metaheuristics drastically and, thus, serves as a motivation for future research into SSR or splitting techniques for DSE.

description: The advent of technologies introduced into both newsrooms and the American culture in the past ten years has changed the needs and habits of print and television journalists. The proliferation of information on the Internet, the diffusion of communication technologies such as cell phones and personal digital assistants (PDA) have increased journalists capabilities at both seeking and gathering information for their work. This paper describes a day in the life of three different journalists and their information seeking needs and behaviors throughout the course of that day. The paper analyzes the journalists' behaviors and needs using a model created by Nicholas and Martin (1998) that characterizes information needs. The journalists participating in the study used new technologies such as the Internet, PDAs and cell phones at varying levels, depending upon their personal preferences and their views regarding the most efficient and reliable means of reporting the news.

 Kant & Gupta 1998. p. 185, Pl. 84, fig. 1. (misspelled K. “lativica”); Ott, 2009, pp. 323 & 633.
 Distribution in India: Himalayas (north-east side, Leh Town, Ladakh district, east Kashmr, on the Tibetan frontier).
 Notes: Kyliniella is monotypic, exclusively freshwater (Kylin 1956) with wide distribution, reported sporadically from Europe (Eloranta & Kwandrans 2007; García-Fernández et al. 2012) and North America (Sheath & Vis 2015). Typical plants of K. latvica possess a pseudoparenchymatous discoid base with upright unbranched filaments, each cell with several parietal discoid blue-green plastids without pyrenoids (see Sheath 2003; Eloranta & Kwandrans 2007, p. 27, fig. 8a, b, c). On the contrary, the Indian plants are described as having a heterotrichous basal layer giving rise to erect filaments, each cell having a single chloroplast (see Kant & Gupta 1998, Pl. 84, fig. 1), similar to some species of Audouinella. Ott (2009, p. 626) pointed out that Krishnamurthy’s (1953) generalized remark that Kyliniella may be a juvenile stage of Compsopogon and/or Kneuckeria Schmidle is untenable, an opinion with which we concur, because it was made without any supporting evidence. The monotypic Kneuckeria pulchra Schmidle is reported so far only from the Sinai Peninsula. A notable, but unverified feature of Kyliniella latvica, is the putative presence of sexual reproduction (Flint 1953; Vis & Sheath 1993; Sheath 2003). Yoon et al. (2006), based on limited molecular data, referred K. latvica to the lineage 2 of the Porphyridiales, of the seven major lineages of red algae. Kyliniella latvica appears to be very close to Bangiopsis subsimplex (Montagne) Schmitz and Purpureofilum apyrenoidigerum J.A.West, Zuccarello & J.L.Scott as inferred from their phylogenetic analyses. The report of K. latvica in India (Kant & Gupta 1998) remains to be confirmed.

description: Within the last 20 to 30 years, researchers have conducted studies of the genealogy community. Unfortunately, these studies have not recognized the millennial generation, as an active group of the genealogical community. Millennials have overtaken the Baby Boomer generation as the largest age group in America. Regarding the generation's population size, why haven't millennials been widely studied in the genealogy community? Few studies about millennials and genealogy leave numerous questions left to be answered: How much is known about the millennial generation in genealogy studies?  What thoughts do millennials have in regards to genealogy? What factors drive their feelings? The researcher conducted a genealogy-based survey with millennials at the University of North Carolina at Chapel Hill in hopes of uncovering answers about this generation. The findings of this study will help institutions to better understand millennials as recognized members within the genealogical community.

Das den Untersuchungen zugrunde liegende Anwendungsbeispiel entstammt dem Bereich energietechnischer Systeme – für diesen Anwendungskontext wurde im Rahmen von Vorgängerarbeiten eine skalierbare Methodik und Werkzeugumgebung geschaffen, die es ermöglichen, energietechnische Komponenten bis hin zu komplexen energietechnischen Systemszenarien auf virtueller Ebene zu modellieren und unter komplexen Umgebungsbedingungen (z.B. Witterungsverhältnisse, Strombörse) und Anforderungen (z.B. spezifische Charakteristika des Energiemarkts, gesetzliche Rahmenbedingungen) zu simulieren und zu analysieren. Darauf aufsetzend wird in der vorliegenden Arbeit ein algorithmischer KI-Ansatz auf den betrachteten Anwendungskontext adaptiert und für eine systematische Optimierung von Systemszenarien hinsichtlich variierender Zielkriterien eingesetzt – im vorliegenden Fall hinsichtlich einer Optimierung der strukturellen Zusammensetzung von Akteuren beim Ausbau eines bestehenden Netzwerkverbunds, entsprechend der Fragestellung, welcher Technologiemix unter Berücksichtigung konkreter Umgebungsbedingungen und Zielvorgaben einen bestmöglichen Optimierungseffekt zu generieren in der Lage ist. Hierbei wird untersucht, in welcher Weise die Fragestellung in eine für die Anwendung von KI-Ansätzen taugliche Formulierung überführt werden kann und auf welche Weise geeignete Iterationsverfahren und Metriken für eine zielgerichtete Traversierung des Explorationsraums formuliert werden können. Innerhalb einer experimentellen Untersuchung wird am Beispiel eines konkreten Netzwerkszenarios aufgezeigt, dass/inwieweit das entwickelte Lösungsverfahren in der Lage ist, hinsichtlich unterschiedlicher Zielvorgaben (Anpassung an reale Verbraucherkurve, Steigerung des Profits an der Strombörse, Senkung der CO 2 -Emission) eine systematische Optimierung des Netzwerkverbunds zu bewirken.

description: There is a growing interest in exploiting the functional properties of niobium oxides in general and of the T-Nb2O5 polymorph in particular. Fundamental investigations of the properties of niobium oxides are, however, hindered by the availability of materials with sufficient structural perfection. It is expected that high-quality T-Nb2O5 can be made using heteroepitaxial growth. Here, we investigated the epitaxial growth of T-Nb2O5 on a prototype perovskite oxide, SrTiO3. Even though there exists a reasonable lattice mismatch in one crystallographic direction, these materials have a significant difference in crystal structure: SrTiO3 is cubic, whereas T-Nb2O5 is orthorhombic. It is found that this difference in symmetry results in the formation of domains that have the T-Nb2O5 c-axis aligned with the SrTiO3 <001>s in-plane directions. Hence, the number of domain orientations is four and two for the growth on (100)s- and (110)s-oriented substrates, respectively. Interestingly, the out-of-plane growth direction remains the same for both substrate orientations, suggesting a weak interfacial coupling between the two materials. Despite challenges associated with the heteroepitaxial growth of T-Nb2O5, the T-Nb2O5 films presented in this paper are a significant improvement in terms of structural quality compared to their polycrystalline counterparts.

description: Ramsey quantifiers are a natural object of study not only for logic and computer science, but also for the formal semantics of natural language. Restricting attention to finite models leads to the natural question whether all Ramsey quantifiers are either polynomial-time computable or NP-hard, and whether we can give a natural characterization of the polynomial-time computable quantifiers. In this paper, we first show that there exist intermediate Ramsey quantifiers and then we prove a dichotomy result for a large and natural class of Ramsey quantifiers, based on a reasonable and widely-believed complexity assumption. We show that the polynomial-time computable quantifiers in this class are exactly the constant-log-bounded Ramsey quantifiers.

description: We present an IR-monitoring survey with the $Spitzer$ Space Telescope of the star forming region GGD 12-15. Over 1000 objects were monitored including about 350 objects within the central 5 arcminutes which is found to be especially dense in cluster members. The monitoring took place over 38 days and is part of the Young Stellar Object VARiability (YSOVAR) project. The region was also the subject of a contemporaneous 67ks $Chandra$ observation. The field includes 119 previously identified pre-main sequence star candidates. X-rays are detected from 164 objects, 90 of which are identified with cluster members. Overall, we find that about half the objects in the central 5 arcminutes are young stellar objects based on a combination of their spectral energy distribution, IR variability and X-ray emission. Most of the stars with IR excess relative to a photosphere show large amplitude (>0.1 mag) mid-IR variability. There are 39 periodic sources, all but one of these is found to be a cluster member. Almost half of the periodic sources do not show IR excesses. Overall, more than 85% of the Class I, flat spectrum, and Class II sources are found to vary. The amplitude of the variability is larger in more embedded young stellar objects. Most of the Class~I/II objects exhibit redder colors in a fainter state, compatible with time-variable extinction. A few become bluer when fainter, which can be explained with significant changes in the structure of the inner disk. A search for changes in the IR due to X-ray events is carried out, but the low number of flares prevented an analysis of the direct impact of X-ray flares on the IR lightcurves. However, we find that X-ray detected Class II sources have longer timescales for change in the mid-IR than a similar set of non-X-ray detected Class IIs.

description: The Delphi, a method for systematic collection of information from experts, was modified to obtain biological data required for the economic analysis of current and potential cotton insect management practices in western regions of production where boll weevils do not pose a significant pest problem. Cotton insect management and crop production experts provided detailed data regarding current insecticide use patterns, and projected insecticide use and lint yields under an alternate, “optimal” insect management program. These data were used to estimate average cotton yield, insecticide use, and insect control costs under both current conditions and the alternative program for each of seven subregions of western cotton production.

description: The use of periodic magnetic structures to control the magneto-dynamic properties of materials-Magnonics-is a rapidly developing field. In the last decade, a number of studies have shown that metallic films can be patterned or combined in patterns that give rise to well-defined magnetization modes, which are formed due to band folding or band gap effects. To explore and utilize these effects in a wide frequency range, it is necessary to pattern samples at the sub-micrometer scale. However, it is still a major challenge to produce low-loss magnonic structures with periodicities at such length scales. Here, we show that for a prototypical perovskite, La0.7 Sr0.3MnO3, the twinned structural order can be used to induce a magnetic modulation with a period smaller than 100 nm, demonstrating a bottomup approach for magnonic crystal growth. © 2017 IOP Publishing Ltd and Deutsche Physikalische Gesellschaft.

description: This study is a systematic review of literature on electronic health record systems (EHRs) and the evaluation methods performed to study their usability. The purpose was to identify and review the extent of usability testing methods in their respective clinical environments. Full text review was completed for 121 of 753 titles intentionally identified, and 70 final articles were included.
The majority of methodologies reviewed were well established in HCI and the most common was the questionnaire. There was a wide range of study designs in terms of user populations (physicians, nurses, pharmacists, nurse practitioners, physical therapists and others), clinical settings (inpatient and outpatient, ambulatory, pediatric, intensive care units, and others), testing time (pre-implementation or post), and qualitative data analysis. Chosen methodologies and study designs closely depended on study goals, but all of them had large implications for the future of quality healthcare and how to achieve it.

description: We achieve the strong-coupling regime between an ensemble of phosphorus donor spins in a highly enriched 28Si crystal and a 3D dielectric resonator. Spins are polarized beyond Boltzmann equilibrium using spin-selective optical excitation of the no-phonon bound exciton transition resulting in N=3.6×1013 unpaired spins in the ensemble. We observe a normal mode splitting of the spin-ensemble–cavity polariton resonances of 2g√N=580 kHz (where each spin is coupled with strength g) in a cavity with a quality factor of 75 000 (γ≪κ≈60 kHz, where γ and κ are the spin dephasing and cavity loss rates, respectively). The spin ensemble has a long dephasing time (T∗2=9 μs) providing a wide window for viewing the dynamics of the coupled spin-ensemble–cavity system. The free-induction decay shows up to a dozen collapses and revivals revealing a coherent exchange of excitations between the superradiant state of the spin ensemble and the cavity at the rate g√N. The ensemble is found to evolve as a single large pseudospin according to the Tavis-Cummings model due to minimal inhomogeneous broadening and uniform spin-cavity coupling. We demonstrate independent control of the total spin and the initial Z projection of the psuedospin using optical excitation and microwave manipulation, respectively. We vary the microwave excitation power to rotate the pseudospin on the Bloch sphere and observe a long delay in the onset of the superradiant emission as the pseudospin approaches full inversion. This delay is accompanied by an abrupt π-phase shift in the peusdospin microwave emission. The scaling of this delay with the initial angle and the sudden phase shift are explained by the Tavis-Cummings model.

description: A class of (1+2)-dimensional diffusion-convection equations (nonlinear Kolmogorov equations) with time-dependent coefficients is studied with Lie symmetry point of view. The complete group classification is achieved using a gauging of arbitrary elements (i.e. via reducing the number of variable coefficients) with the application of equivalence transformations. Two possible gaugings are discussed in detail in order to show how equivalence groups serve in making the optimal choice.

description: Genealogists represent one of the largest and fastest growing user groups in archives and special collection repositories.  To understand and meet the information-seeking needs of genealogists, archives must utilize regular and standardized user studies.   This paper studies genealogist user data that analyzes user background, and information-seeking behavior at the archives and online.  From this data, the North Carolina State Archives will be better prepared to meet the research and service needs of genealogists, including the resources, materials, and digitized records they prefer.  Similar archives and institutions will also benefit from the results to improve their services to genealogists and conduct future user studies.

description: In the last decade, integrated logistics has become an important challenge in the development of wireless communication, identification and sensing technology, due to the growing complexity of logistics processes and the increasing demand for adapting systems to new requirements. The advancement of wireless technology provides a wide range of options for the maritime container terminals. Electronic devices employed in container terminals reduce the manual effort, facilitating timely information flow and enhancing control and quality of service and decision made. In this paper, we examine the technology that can be used to support integration in harbor's logistics. In the literature, most systems have been developed to address specific needs of particular harbors, but a systematic study is missing. The purpose is to provide an overview to the reader about which technology of integrated logistics can be implemented and what remains to be addressed in the future.
Metrics for the evaluation of warm convective cloud fields in a large-eddy simulation with Meteosat images

description: The representation of warm convective clouds in atmospheric models and satellite observations can considerably deviate from each other partly due to different spatial resolutions. This study aims to establish appropriate metrics to evaluate high-resolution simulations of convective clouds by the ICON Large-Eddy Model (ICON-LEM) with observations from Meteosat SEVIRI over Germany. The time series and frequency distributions of convective cloud fraction and liquid water path (LWP) are analyzed. Furthermore, the study focuses on size distributions and decorrelation scales of warm convective cloud fields. The investigated metrics possess a pronounced sensitivity to the apparent spatial resolution. At the fine spatial scale, the simulations show higher occurrence frequencies of large LWP values and a factor of two to four smaller convective cloud fractions. Coarse-graining of simulated fields to the optical resolution of Meteosat essentially removes the differences between the observed and simulated metrics. The distribution of simulated cloud sizes compares well with the observations and can be represented by a power law, with a moderate resolution sensitivity. A lower limit of cloud sizes is identified, which is 8–10 times the native grid resolution of the model. This likely marks the effective model resolution beyond which the scaling behaviour of considered metrics is not reliable, implying that a further increase in spatial resolution would be desirable to better resolve cloud processes below 1 km. It is finally shown that ICON-LEM is consistent with spatio-temporal decorrelation scales observed with Meteosat having values of 30 min and 7 km, if transferred to the true optical satellite resolution. However, the simulated Lagrangian decorrelation times drop to 10 min at 1 km resolution, a scale covered by the upcoming generation of geostationary satellites.
