Abstract
OBJECTIVE To determine effects of repeated use and resterilization on structural and functional integrity of microwave ablation (MWA) antennas.
SAMPLE 17 cooled-shaft MWA antennas (3 groups of 5 antennas/group and 2 control antennas).
PROCEDURES 1, 2, and 3 ablations in the livers of bovine cadavers were performed at the maximum recommended settings. Antennas were cleaned and sterilized in hydrogen peroxide plasma, and the process was repeated (reprocessing cycle; n = 6). Control antennas were only sterilized (6 times). Aerobic and anaerobic bacterial cultures were performed, and antennas were microscopically assessed for damage.
RESULTS 6 cycles were completed. Thirteen of 15 MWA antennas remained functional for up to 4 cycles, 10 were functional after 5 cycles, and only 7 were functional after 6 cycles. Progressive tearing of the silicone coating of the antennas was observed, with a negative effect of the number of cycles for silicone tearing. Size of the ablation zone decreased mildly over time after cycles 5 and 6; however, this was not considered clinically relevant. No significant changes in the shape of ablation zones were detected. All cultures yielded negative results, except for an isolated case, which was considered a contaminant.
CONCLUSIONS AND CLINICAL RELEVANCE Structural and functional integrity of the microwave antennas remained acceptable during repeated use and reprocessing for up to 4 cycles. However, there was a decrease in functional integrity at cycles 5 and 6. We suggest that these microwave antennas be subjected to > 3 reprocessing cycles. Antennas should be carefully examined before reuse.

A year has passed since the celebration of 100th years of Indonesian archaeology. On June 14th 2013, this golden moment was commemorated by institutions and individuals. The nostalgic euphoria has been transformed into the festive spirit of various events. Ranging from seminars to exhibitions. From small gatherings to the colosal stages. There is a pride that rised from the establishment of this 100th anniversary. This article tries to discuss the current situation in the Indonesian archaeology by dissect the anatomy of archaeological research in the Moluccas Archipleago. The ideas disscussed will cover the review of archaeological research in the Moluccas historically; followed by observing the recent activities to understand the impacts of archaeological research for the region and its communities; and finally initiate the discussion on choosing the direction and the role of archaeological research for the academic and social purpose in the near future.Tak terasa hampir setahun telah dilewati sejak perayaan satu abad purbakala Nusantara. Tepat tanggal 14 Juni 2013 silam, momentum emas ini diperingati segenap insan arkeologi Indonesia. Gempita nostalgia dikemas menjadi semangat perayaan dalam berbagai kegiatan. Mulai dari seminar sampai pameran. Sekedar sukuran hingga pentas kolosal. Ada kebanggaan yang membuncah dari angka mapan usia ke-100. Kini pesta telah usai. Segalanya kembali senyap. Rasanya tepat untuk mulai merenung. Tentang makna menjadi lembaga dengan umur yang bahkan lebih sepuh dari negara. Memikirkan kembali kiprah pun capaian. Menemukenali kekurangan dan kendala. Adakah arkeologi akan terus mengalir dengan wawasan klasik business as usual? Ataukah memilih bercermin pada jernih kondisi kekinian dan bergegas membenahi diri? Makalah ini mencoba mengamati kondisi terkini arkeologi nasional dengan membedah anatomi penelitian arkeologi di Kepulauan Maluku dalam kerangka kronologis.

In the early period of the spice trade, Makian Island Moti Island are the main source in the production of cloves. This condition is the main factor that attaracted tthe presence of Europeans that its influences still can be traced recently. Evidence of the presence of European nations can be seen from the distribution of the fort in the island Makian and Moti Island. This research is intended to uncover the factors that underlie the formation of a network of fortifications in the two islands. Using the method of interpretation of the distribution pattern of the castle and the relationship between regions, this paper uncovered that the main factors the formation of a network of fortifications in the region is the natural conditions or geographical factors, so that consideration of the establishment of each fort associated with the monitoring of safety conditions, supervision of the marketing of cloves, as well as efforts to maintain the existence of a colonial power in the region.Pada periode awal perdagangan rempah-rempah, Pulau Makian dan Pulau Moti adalah sumber utama produksi cengkih. Hal inilah kemudian menjadi daya tarik kehadiran bangsa Eropa yang hingga saat ini masih dapat disaksikan jejak pengaruhnya. Bukti-bukti kehadiran bangsa Eropa tersebut dapat dilihat dari sebaran benteng yang ada di Pulau Makian dan Pulau Moti. Penelitian ini bertujuan untuk mengungkap faktor-faktor yang melatari terbentuknya jaringan perbentengan yang ada di kedua pulau tersebut. Melalui metode penafsiran terhadap pola sebaran benteng dan hubungan antar wilayah, tulisan ini berhasil mengungkap bahwa faktor utama terbentuknya jaringan perbentengan di wilayah ini adalah kondisi alam atau faktor geografis, sehingga pertimbangan atas pendirian setiap benteng berkaitan dengan pengawasan terhadap kondisi keamanan, pengawasan terhadap tata niaga cengkih, serta upaya untuk mempertahankan eksistensi kekuasan kolonial di wilayah ini.

Abstract
Deep near-IR images from the VISTA Variables in the Vía Láctea (VVV) Survey were used to search for RR Lyrae stars in the Southern Galactic plane. A sizable sample of 404 RR Lyrae of type ab stars was identified across a thin slice of the fourth Galactic quadrant (295° < ℓ < 350°, −2.°24 < b < −1.°05). The sample’s distance distribution exhibits a maximum density that occurs at the bulge tangent point, which implies that this primarily Oosterhoff type I population of RRab stars does not trace the bar delineated by their red clump counterparts. The bulge RR Lyrae population does not extend beyond ℓ ∼ 340°, and the sample’s spatial distribution presents evidence of density enhancements and substructure that warrants further investigation. Indeed, the sample may be employed to evaluate Galactic evolution models, and is particularly lucrative since half of the discovered RR Lyrae are within reach of Gaia astrometric observations.

Abstract
We announce the discovery of KELT-12b, a highly inflated Jupiter-mass planet transiting the mildly evolved, V = 10.64 host star TYC 2619-1057-1. We followed up the initial transit signal in the KELT-North survey data with precise ground-based photometry, high-resolution spectroscopy, precise radial velocity measurements, and high-resolution adaptive optics imaging. Our preferred best-fit model indicates that the host star has

. The planetary companion has

g cm−3, making it one of the most inflated giant planets known. Furthermore, for future follow-up, we report a high-precision time of inferior conjunction in

of 2,457,083.660459 ± 0.000894 and period of

days. Despite the relatively large separation of ∼0.07 au implied by its ∼5.03-day orbital period, KELT-12b receives significant flux of

erg s−1 cm−2 from its host. We compare the radii and insolations of transiting gas giant planets around hot (

K) and cool stars, noting that the observed paucity of known transiting giants around hot stars with low insolation is likely due to selection effects. We underscore the significance of long-term ground-based monitoring of hot stars and space-based targeting of hot stars with the Transiting Exoplanet Survey Satellite to search for inflated gas giants in longer-period orbits.
On the Relation of Silicates and SiO Maser in Evolved Stars
Authors: Liu Jiaming , Jiang Biwei 
Published: March 2017

Abstract
The SiO molecule is one of the candidates for the seed of silicate dust in the circumstellar envelope of evolved stars, but this opinion is challenged. In this work we investigate the relation of the SiO maser emission power and the silicate dust emission power. With both our own observation by using the PMO/Delingha 13.7 m telescope and archive data, a sample is assembled of 21 SiO v = 1, J = 2 − 1 sources and 28 SiO v = 1, J = 1 − 0 sources that exhibit silicate emission features in the ISO/SWS spectrum as well. The analysis of their SiO maser and silicate emission power indicates a clear correlation, which is not against the hypothesis that the SiO molecules are the seed nuclei of silicate dust. On the other hand, no correlation is found between SiO maser and silicate crystallinity, which may imply that silicate crystallinity does not correlate with mass-loss rate.
Which Bow Shock Theory, Gasdynamic or Magnetohydrodynamic, Better Explains CME Stand-off Distance Ratios from LASCO-C2 Observations ?

Published: March 2017

Abstract
It is generally believed that fast coronal mass ejections (CMEs) can generate their associated shocks, which are characterized by faint structures ahead of CMEs in white-light coronagraph images. In this study, we examine whether the observational stand-off distance ratio, defined as the CME stand-off distance divided by its radius, can be explained by bow shock theories. Of 535 SOHO/LASCO CMEs (from 1996 to 2015) with speeds greater than 1000 km s−1 and angular widths wider than 60°, we select 18 limb CMEs with the following conditions: (1) their Alfvénic Mach numbers are greater than one under Mann’s magnetic field and Saito’s density distributions; and (2) the shock structures ahead of the CMEs are well identified. We determine observational CME stand-off distance ratios by using brightness profiles from LASCO-C2 observations. We compare our estimates with theoretical stand-off distance ratios from gasdynamic (GD) and magnetohydrodynamic (MHD) theories. The main results are as follows. Under the GD theory, 39% (7/18) of the CMEs are explained in the acceptable ranges of adiabatic gamma (γ) and CME geometry. Under the MHD theory, all the events are well explained when we consider quasi-parallel MHD shocks with γ = 5/3. When we use polarized brightness (pB) measurements for coronal density distributions, we also find similar results: 8% (1/12) under GD theory and 100% (12/12) under MHD theory. Our results demonstrate that the bow shock relationships based on MHD theory are more suitable than those based on GD theory for analyzing CME-driven shock signatures.
Tibial periosteal ganglion cyst: The ganglion in disguise

Published: March 2017

AbstractSoft tissue ganglions are commonly encountered cystic lesions around the wrist presumed to arise from myxomatous degeneration of periarticular connective tissue. Lesions with similar pathology in subchondral location close to joints, and often simulating a geode, is the less common entity called intraosseous ganglion. Rarer still is a lesion produced by mucoid degeneration and cyst formation of the periostium of long bones, rightly called the periosteal ganglion. They are mostly found in the lower extremities at the region of pes anserinus, typically limited to the periosteum and outer cortex without any intramedullary component. We report the case of a 62 year-old male who presented with a tender swelling on the mid shaft of the left tibia, which radiologically suggested a juxtacortical lesion extending to the soft tissue or a soft tissue neoplasm eroding the bony cortex of tibia. It was later diagnosed definitively as a periosteal ganglion in an atypical location, on further radiologic work-up and histopathological correlation.
Castleman's disease: A rare indication for endovascular therapy for hemoptysis

Published: March 2017

AbstractCastleman's disease (CD) is a rare lympho-proliferative disorder due to faulty immune regulation resulting in proliferation of lymphatic tissue. The vascular supply to these lesions have been reported to arise from the bronchial, internal mammary and the intercostal arteries. We report a case of hemoptysis secondary to intrathoracic CD with vascular supply arising from the left inferior phrenic artery which was successfully embolised with polyvinyl alcohol (PVA) particles.

Published: March 2017

Abstract
Aim: Acute organophosphate (OP) pesticide poisoning causes substantial morbidity and mortality worldwide. Many imaging modalities, such as computerized tomography (CT), magnetic resonance imaging (MRI), and single photon emission computed tomography (SPECT) of the brain, have been used for quantitative assessment of the acute brain insult caused by acute OP poisoning. Perfusion defects on SPECT in acutely poisoned patients with OPs have been described, however, MR perfusion abnormalities have not been described in the literature. MR perfusion Imaging has the advantage of having higher spatial resolution, no radiation, and better availability. Materials and Methods:In this prospective study, 20 patients who ingested OP compounds were included. All the patients underwent brain SPECT on a dual head SPECT gamma camera and MRI brain on a 1.5T MR system. Neurocognitive tests were performed for all patients.Results: SPECT showed perfusion defects in 7 patients and total number of perfusion defects were 29. On MR perfusion, based on the cut-off values of normalized cerebral blood volume (nCBV) ratios and normalized cerebral blood flow (nCBF) ratios, the total number of patients showing perfusion defects were 6 and 8; and the total number of perfusion defects were 29 and 45, respectively. There was significant difference of the nCBV ratios and nCBF ratios between the control group (n = 20) and positive patients group (n = 6 and n = 8, respectively) (P > 0.05). All the defects seen on SPECT were well appreciated on nCBF maps (MRI perfusion) suggestive of 100% correlation. Conclusion: MR perfusion imaging can be used as an effective modality for evaluation in acute OP poisoning.
Normality Versus Paracompactness in Locally Compact Spaces
Authors: Dow Alan , Tall Franklin D. 
Published: March 2017

AbstractThis note provides a correct proof of the result claimed by the second author that locally compact normal spaces are collectionwise Hausdorff in certain models obtained by forcing with a coherent Souslin tree. A novel feature of the proof is the use of saturation of the non-stationary ideal on ω1, as well as of a strong form of Chang's Conjecture. Together with other improvements, this enables the consistent characterization of locally compact hereditarily paracompact spaces as those locally compact, hereditarily normal spaces that do not include a copy of ω1.
Impact of Local Grid Refinements of Spherical Centroidal Voronoi Tessellations for Global Atmospheric Models
Authors: Liu Yudi , Yang Taojin 
Published: March 2017

AbstractIn order to study the local refinement issue of the horizontal resolution for a global model with Spherical Centroidal Voronoi Tessellations (SCVTs), the SCVTs are set to 10242 cells and 40962 cells respectively using the density function. The ratio between the grid resolutions in the high and low resolution regions (hereafter RHL) is set to 1:2, 1:3 and 1:4 for 10242 cells and 40962 cells, and the width of the grid transition zone (for simplicity, WTZ) is set to 18° and 9° to investigate their impacts on the model simulation. The ideal test cases, i.e. the cosine bell and global steady-state nonlinear zonal geostrophic flow, are carried out with the above settings. Simulation results showthat the larger the RHL is, the larger the resulting error is. It is obvious that the 1:4 ratio gives rise to much larger errors than the 1:2 or 1:3 ratio; the errors resulting from the WTZ is much smaller than that from the RHL. No significant wave distortion or reflected waves are found when the fluctuation passes through the refinement region, and the error is significantly small in the refinement region. Therefore,when designing a local refinement scheme in the global model with SCVT, the RHL should be less than 1:4, i.e., the error is acceptable when the RHL is 1:2 or 1:3.
Designing Several Types of Oscillation-Less and High-Resolution Hybrid Schemes on Block-Structured Grids
Authors: Jiang Zhenhua , Yan Chao , Yu Jian , Lin Boxi 
Published: March 2017

AbstractAn idea of designing oscillation-less and high-resolution hybrid schemes is proposed and several types of hybrid schemes based on this idea are presented on block-structured grids. The general framework, for designing various types of hybrid schemes, is established using a Multi-dimensional Optimal Order Detection (MOOD) method proposed by Clain, Diot and Loubère [1]. The methodology utilizes low dissipation or dispersion but less robust schemes to update the solution and then implements robust and high resolution schemes to deal with problematic situations. A wide range of computational methods including central scheme, MUSCL scheme, linear upwind scheme and Weighted Essentially Non Oscillatory (WENO) scheme have been applied in the current hybrid schemes framework. Detailed numerical studies on classical test cases for the Euler system are performed, addressing the issues of the resolution and non-oscillatory property around the discontinuities.

Abstract. The extreme dust storm that affected the Middle East and the eastern Mediterranean in September 2015 resulted in record-breaking dust loads over Cyprus with aerosol optical depth exceeding 5.0 at 550 nm. We analyse this event using profiles from the European Aerosol Research Lidar Network (EARLINET) and the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO), geostationary observations from the Meteosat Second Generation (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI), and high-resolution simulations from the Regional Atmospheric Modeling System (RAMS). The analysis of modelling and remote sensing data reveals the main mechanisms that resulted in the generation and persistence of the dust cloud over the Middle East and Cyprus. A combination of meteorological and surface processes is found, including (a) the development of a thermal low in the area of Syria that results in unstable atmospheric conditions and dust mobilization in this area, (b) the convective activity over northern Iraq that triggers the formation of westward-moving haboobs that merge with the previously elevated dust layer, and (c) the changes in land use due to war in the areas of northern Iraq and Syria that enhance dust erodibility.

En sintonía con los contenidos del presente dosier, el objetivo de este artículo es relacionar el debate sobre la naturaleza, actualidad y efectos del populismo –apelando tanto a las visiones clásicas como a planteos más recientes– con los fenómenos y procesos que caracterizan la realidad política boliviana y, de forma más general, latinoamericana. Al hacer esto, se profundiza sobre la relación entre populismo y democracia y se discute la pertinencia de adjudicar (o no adjuticar) un carácter populista al gobierno que encabeza Evo Morales.
Destrucción de naciones. El arma global de Estados Unidos desarrollada en Bolivia
Authors: Zambrana M. Juan Carlos 
Published: March 2017

A partir de la idea de que la "construcción de la nación” siempre comienza con la destrucción de la nación original, y que la etapa de la reconstrucción ya no se realiza, se postula que hoy por hoy ese proceso se limita a la destrucción de naciones. Esa destrucción se hace con la intervención militar, como en el caso de Irak, o sin ella, como en gran parte del planeta. Centrándose en el caso boliviano pre-1952, el autor de este trabajo ofrece una crónica de esa operacion encubierta conceptualizada como “destrucción de naciones”. La crónica está reconstruida con documentos desclasificados del Departamento de Estado de los Estados Unidos, muchos de los cuales fueron originalmente secretos y permanecieron así por mucho tiempo.
