Boundary Layer Height and Buoyancy Determine the Horizontal Scale of Convective Self-Aggregation
Authors: Yang Da 
Published: November 2017

Abstract
Organized rainstorms and their associated overturning circulations can self-emerge over an ocean surface with uniform temperature in cloud-resolving simulations. This phenomenon is referred to as convective self-aggregation. Convective self-aggregation is argued to be an important building block for tropical weather systems and may help regulate tropical atmospheric humidity and thereby tropical climate stability. Here the author presents a boundary layer theory for the horizontal scale λ of 2D (x, z) convective self-aggregation by considering both the momentum and energy constraints for steady circulations. This theory suggests that λ scales with the product of the boundary layer height h and the square root of the amplitude of density variation between aggregated moist and dry regions in the boundary layer, and that this density variation mainly arises from the moisture variation due to the virtual effect of water vapor. This theory predicts the following: 1) the order of magnitude of λ is ~2000 km, 2) the aspect ratio of the boundary layer λ/h increases with surface warming, and 3) λ decreases when the virtual effect of water vapor is disabled. These predictions are confirmed using a suite of cloud-resolving simulations spanning a wide range of climates.
Monte Carlo Study of UAV-Measurable Albedo over Arctic Sea Ice
Authors: Podgorny Igor , Lubin Dan , Perovich Donald K. 
Published: November 2017

AbstractIn anticipation that unmanned aerial vehicles (UAVs) will have a useful role in atmospheric energy budget studies over sea ice, a Monte Carlo model is used to investigate three-dimensional radiative transfer over a highly inhomogeneous surface albedo involving open water, sea ice, and melt ponds. The model simulates the spatial variability in 550-nm downwelling irradiance and albedo that a UAV would measure above this surface and underneath an optically thick, horizontally homogeneous cloud. At flight altitudes higher than 100 m above the surface, an airborne radiometer will sample irradiances that are greatly smoothed horizontally as a result of photon multiple reflection. If one is interested in sampling the local energy budget contrasts between specific surface types, then the UAV must fly at a low altitude, typically within 20 m of the surface. Spatial upwelling irradiance variability in larger open water features, on the order of 1000 m wide, will remain apparent as high as 500 m above the surface. To fully investigate the impact of surface feature variability on the energy budget of the lower troposphere ice–ocean system, a UAV needs to fly at a variety of altitudes to determine how individual features contribute to the area-average albedo.
Recall of structured radiology reports is significantly superior to that of unstructured reports
Authors: Buckley Bryan W , Daly Leslie , Allen Grainne N , Ridge Carole A 
Published: November 2017

Objective:
To measure recall of structured compared with unstructured radiology reports.

Methods:
Institutional review board approval was obtained. Four hypothetical radiology reports, two structured and two unstructured reports, were created for the purposes of this study by an experienced consultant radiologist. The reports, each followed immediately by a multiple-choice questionnaire listing possible diagnoses from the report, were distributed to the members of two national physician associations using a web-based survey tool. Based on the number of correct responses, correct critical findings and incorrect responses, rates per number of potential diagnoses were calculated for each individual and averaged. The paired sign test compared results between structured and unstructured reports.

Results:
148 respondents completed the survey, 126 (85.1%) of whom were physicians. The mean percentage of incorrect diagnoses was 4.5% for structured reports compared with 16.7% for unstructured reports (p &lt; 0.001). The average rate of critical diagnosis recall was 82.7% for structured reports and 65.1% for unstructured reports (p &lt; 0.001). The average percentage of all diagnoses detected for structured compared with unstructured reports was 64.3 and 59.0%, respectively (p = 0.007).

Conclusion:
Recall of structured radiology reports is significantly superior to recall of unstructured reports immediately after reading the report.

Advances in knowledge:
A structured radiology report format can positively impact the referring clinician’s ability to recall the critical findings with statistically significance.
Script doctoring and authorial control in Hollywood and independent American cinema
Authors: Bordino Alex W. 
Published: November 2017

Abstract
This study seeks to elucidate the role of the ‘script doctor’ in both Hollywood and independent American cinema. It attempts to reveal how script doctors, considering them to be cultural producers in their own right, create meaning in their doctored works. It poses several questions: Who are script doctors and how do they perceive their work as meaningful or not? Has this changed over time? Is this different for independent film producers, where the practice may be less formalized and institutionalized? Is the role of script doctor perceived in a certain way, either as a prestigious practice only conducted by seasoned screenwriters or as a lower form of professional writing? Finally, does their role in the production process problematize how we attribute authorship to some writers and not others? Archival material will be analysed in order to trace this practice historically, while this study will also draw from my own personal experience editing scripts for independent filmmakers, thus attempting to compare how historical, institutional script development practices may differ from independent practices where the role may be defined differently, in my case as a ‘script editor’, not a ‘script doctor’. Beyond considering script doctors as cultural producers who create meaning in and through their work, this study shall additionally examine how and where credit is given to various participants involved in the writing process, problematizing typical authorial associations.

Published: November 2017

AbstractThe macrophyte plant distribution in some aquatic habitats and their availability for monitoring the PAH contamination were investigated in Kocaeli Province of Turkey. Alisma plantago-aquatica L. was collected to evaluate polyaromatic hydrocarbon (PAH) contamination in four aquatic habitats located nearby or distant to the industrial facilities and populated city center. Concentrations of eight PAH congeners were measured in A. plantagoaquatica leaves using gas chromatography. PAH sources were estimated using the following ratios, Fluoranthene / (Fluoranthene + Pyrene), Benzo(a)anthracene / (Benzo(a) anthracene + Chrysene) and Anthracene / (Anthracene + Phenanthrene) and were found to be pyrogenic-sourced in all stations. Since the ratios of congeners indicate the pyrogenic contamination, atmospheric deposition can be considered as the main pathway for PAH transportation. The highest ΣPAH concentration (798 μg kg

Abstract
Medical information system (MIS) is at the heart of information technology (IT) implementation policies in healthcare systems around the world. Different architecture and application models of MIS are developed. Despite of obvious advantages and benefits, application of MIS in everyday practice is slow. On the background of analysis of the existing models of MIS in Georgia has been created a multi-user web-based approach. This article will present the architecture of the system and its application for cytology quality assurance programs. Five hundred Georgian language electronic medical records from the cervical screening activity illustrated by images were selected for quality assurance program. The primary goal of the MIS is patient management. However, the system can be used for quality assurance programs. The ideal of healthcare in the information age must be to create a situation where healthcare professionals spend more time creating knowledge from medical information and less time managing medical information. The application of easily available and adaptable technology and improvement of the infrastructure conditions is the basis for eHealth applications. The MIS is perspective and actual technology solution. It can be used for cytology quality assurance programs.

Published: November 2017

Abstract
This article presents the dual-band of a single patch antenna that can operate at a frequency of 2.47 to 5.04 GHz, which is available in WLANs (IEEE 802.11). The beam pattern of the antenna can be switched by changing the position of shorted-circuit points at each edge of the antenna. The advantage of the proposed antenna is that it is a simple structure which is small in size, weighs little and has an easily adjustable beam. In addition, the antenna is tested under real circumstances using the existing WLAN infrastructure. The results confirm that the signal strength can be improved when the proposed switched beam antenna is utilized.

AbstractReverse movement of patients in search of cheaper medical treatment from developed countries to undeveloped countries caused the birth of new phenomenon called medical tourism. Moreover, increasing value of medical tourism market each year draws attention of countries that are aiming to increase their economic growth. In this regard, the potential of Alanya as a medical tourism destination has been tried to determine in this paper. Therefore, it can be said that, the main objective of this research is to determine medical tourism potential of Alanya by taking into account the strengths and weaknesses of the destination as well. For this purpose, face-to-face interviews were conducted with an expert from each hospital and the county health department in Alanya, then these were transcripted into word documents and analyzed with NVivo 8.0. Consequently, it has been found that medical tourism potential of Alanya consist of thirteen sub-factors, which are respectively “Workforce”, “Climate”, “Central Asian Countries”, “Geographic Location”, “Incentive Policies”, “Price”, “Facilitators”, “Service Quality”, “Accessibility”, “Hospital Investments”, “Technological Equipment”, “Conjectural Situation” and “Vacation”. It can be said that, Alanya can benefit from job creation potential, decreasing foreign currency deficit because of service export and spillover effect to other sectors like in other destinations by using its potential to take part in medical tourism.
Blocks to, and building blocks of, narrativity: Fragments, anecdotes, and narrative lines in David Markson’sReader’s block
Authors: Keskinen Mikko 
Published: November 2017

AbstractDavid Markson’sReader’s block(1996) consists of 193 pages of quotations, anecdotes, names, and fragments. The book bears the paratext “A novel,” and the work has indeed been read as a narrative whole, in which “an aging author [...] contemplates the writing of a novel.” By being out of ordinary and therefore worth of telling, the anecdotes or curiosities seemingly fulfill the requirements of a “natural” narrative as defined by Monika Fludernik (1996). However, a mass of such mini-narratives, mixed with even more fragmentary texts, seems to defy narrativity (and tellability). In my reading, the ostensive block to narrativity also functions as its very building block. Thanks to polysemy,blockcan relate to a block of a city, of stone at a gravesite, of text on a printed page, and of index cards. The seemingly dispersed fragments begin to gravitate around these semantic blocks and yield discrete but intertwining narrative lines. The very text claiming to deal with blockages performatively, as a finished book, testifies to the opposite: the mass of texts and plans proves that the ability to work on writing is not lost. Blocks that obstruct also construct, and the demediated novelistic medium still mediates as a form and repurposed content.
Framing absence: A narratology of the empty page
Authors: Domsch Sebastian 
Published: November 2017

AbstractNarrative experimentation has seen many forms, but among the most radical strategies might be the complete absence of text. Printed text is largely determined through its physical presence on the page, it defines itself by where it is, and the performance of the present text determines the flow of narrative time. Silences and absences are usually created semantically, with a present text telling about an absence. Only rarely do texts stage emptiness through the actual absence of text. But when they do, they considerably expand the narrative range of expression of the printed page. In this paper I will look at the narratology of the empty page by analyzing and comparing a number of texts that stage or emphasize the actual absence of text from the page. There are some narrative texts that use their medial form as text printed on a page and bound in a codex not only to narrate absences, but also to stage them outside of the text proper, or rather, through the actual absence of text leading the recipient’s awareness to the page as a frame of reference that potentially carries semantic value. I will contrast different techniques of “framing absence” in texts by David Mitchell (number9dream), Jonathan Safran Foer (Tree of codes), B. S. Johnson (House mother normal) and Mark Z. Danielewski (House of leaves). These examples will show how literary texts can use their own mediality and materiality to reflect on the general relation between all three.

Published: November 2017

Abstract
The normal life of a transformer is well above 25 years. The economical operation of the distribution system has its roots in the equipments being used. The economy being such, that it is financially advantageous to replace transformers with more than 15 years of service in the second perennial market. Testing of transformer is required, as its an indication of the extent to which a transformer can comply with the customers specified requirements and the respective standards (IEC 60076-3). In this paper, induced over voltage testing on transformers using enhanced Z source inverter is discussed. Power electronic circuits are now essential for a whole array of industrial electronic products. The bulky motor generator set, which is used to generate the required frequency to conduct the induced over voltage testing of transformers is nowadays replaced by static frequency converter. First conventional Z-source inverter, and second an enhanced Z source inverter is being used to generate the required voltage and frequency to test the transformer for induced over voltage test, and its characteristics is analysed.
Optimisation of amplitude distribution of magnetic Barkhausen noise
Authors: Pal’a Jozef , Jančárik Vladimír 
Published: November 2017

Abstract
The magnetic Barkhausen noise (MBN) measurement method is a widely used non-destructive evaluation technique used for inspection of ferromagnetic materials. Besides other influences, the excitation yoke lift-off is a significant issue of this method deteriorating the measurement accuracy. In this paper, the lift-off effect is analysed mainly on grain oriented Fe-3%Si steel subjected to various heat treatment conditions. Based on investigation of relationship between the amplitude distribution of MBN and lift-off, an approach to suppress the lift-off effect is proposed. Proposed approach utilizes the digital feedback optimising the measurement based on the amplitude distribution of MBN. The results demonstrated that the approach can highly suppress the lift-off effect up to 2 mm.
Construction for obtaining trellis run length limited error control codes from convolutional codes
Authors: Farkaš Peter , Schindler Frank 
Published: November 2017

Abstract
Recently a new construction of run length limited block error control codes based on control matrices of linear block codes was proposed. In this paper a similar construction for obtaining trellis run length limited error control codes from convolutional codes is described. The main advantage of it, beyond its simplicity is that it does not require any additional redundancy except the one which is already contained in the original convolutional error control code. One example is presented how to get such a code from a convolutional low density parity check code.
Laser induced adjustment of the conductivity of rare earth doped Mn-Zn nanoferrite
Authors: El-Dek S. I. , Ahmed M. A. , Eltawil Alaaeldin A. 
Published: November 2017

AbstractTwo series of Mn-Zn nanoferrites (namely Mn1-xZnxFe2O4and Mn1-xZnxFe2-yRyO4) were synthesized using standard ceramic technique. X-ray diffraction and FT-IR were employed in the chacterization of the nanopowder. The X-ray density for each sample increased after laser irradiation which was correlated with the decrease in the unit cell volume. The study involved the thermal and frequency variation of the dielectric constant and AC conductivity of the investigated samples before and after laser irradiation. The later altered the conductivity by decreasing its value for the rare earth doped samples except for the Sm3+doped one. The results suggested the exploitation of Mn-Zn doped rare earth nanoferrites in many technological applications demanding high resistivity.
