OBJECTIVEThe aim of this systematic review is to offer an objective summary of the published literature relating to stereotactic radiosurgery (SRS) for tremor and consensus guideline recommendations.METHODSThis systematic review was performed up to December 2016. Article selection was performed by searching the MEDLINE (PubMed) and EMBASE electronic bibliographic databases. The following key words were used: “radiosurgery” and “tremor” or “Parkinson’s disease” or “multiple sclerosis” or “essential tremor” or “thalamotomy” or “pallidotomy.” The search strategy was not limited by study design but only included key words in the English language, so at least the abstract had to be in English.RESULTSA total of 34 full-text articles were included in the analysis. Three studies were prospective studies, 1 was a retrospective comparative study, and the remaining 30 were retrospective studies. The one retrospective comparative study evaluating deep brain stimulation (DBS), radiofrequency thermocoagulation (RFT), and SRS reported similar tremor control rates, more permanent complications after DBS and RFT, more recurrence after RFT, and a longer latency period to clinical response with SRS. Similar tremor reduction rates in most of the reports were observed with SRS thalamotomy (mean 88%). Clinical complications were rare and usually not permanent (range 0%–100%, mean 17%, median 2%). Follow-up in general was too short to confirm long-term results.CONCLUSIONSSRS to the unilateral thalamic ventral intermediate nucleus, with a dose of 130–150 Gy, is a well-tolerated and effective treatment for reducing medically refractory tremor, and one that is recommended by the International Stereotactic Radiosurgery Society.

Published: February 2018

Summary
Objective: This works investigates the time-frequency content of impedance cardiography signals during a propofol-remifentanil anesthesia.
Materials and Methods: In the last years, impedance cardiography (ICG) is a technique which has gained much attention. However, ICG signals need further investigation. Time-Frequency Distributions (TFDs) with 5 different kernels are used in order to analyze impedance cardiography signals (ICG) before the start of the anesthesia and after the loss of consciousness. In total, ICG signals from one hundred and thirty-one consecutive patients undergoing major surgery under general anesthesia were analyzed. Several features were extracted from the calculated TFDs in order to characterize the time-frequency content of the ICG signals. Differences between those features before and after the loss of consciousness were studied.
Results: The Extended Modified Beta Distribution (EMBD) was the kernel for which most features shows statistically significant changes between before and after the loss of consciousness. Among all analyzed features, those based on entropy showed a sensibility, specificity and area under the curve of the receiver operating characteristic above 60%.
Conclusion: The anesthetic state of the patient is reflected on linear and non-linear features extracted from the TFDs of the ICG signals. Especially, the EMBD is a suitable kernel for the analysis of ICG signals and offers a great range of features which change according to the patient’s anesthesia state in a statistically significant way.

Abstract
We present the spectroscopic orbit of LHS 1610A, a newly discovered single-lined spectroscopic binary with a trigonometric distance placing it at 9.9 ± 0.2 pc. We obtained spectra with the TRES instrument on the 1.5 m Tillinghast Reflector at the Fred Lawrence Whipple Observatory located on Mt. Hopkins in AZ. We demonstrate the use of the TiO molecular bands at 7065–7165 Å to measure radial velocities and achieve an average estimated velocity uncertainty of 28 m s−1. We measure the orbital period to be 10.6 days and calculate a minimum mass of 44.8 ± 3.2 M
Jup for the secondary, indicating that it is likely a brown dwarf. We place an upper limit to 3σ of 2500 K on the effective temperature of the companion from infrared spectroscopic observations using IGRINS on the 4.3 m Discovery Channel Telescope. In addition, we present a new photometric rotation period of 84.3 days for the primary star using data from the MEarth-South Observatory, with which we show that the system does not eclipse.
Evolution of the Outflows in NGC 3516

Published: February 2018

Abstract
We analyze the 2011 HST/COS spectrum of the Seyfert 1 galaxy NGC 3516, which demonstrates clear changes in one of the intrinsic absorption troughs (component 5), slight evidence of change in a second trough (component 6), and the appearance of a new absorption trough (component 9). We interpret both the changes and the appearance of the new trough as bulk motion across the line of sight. The implied lower limit on the transverse velocity of component 5 is 360 km s−1, compared to the earlier 2001 HST/STIS spectrum, while the lower limits for components 6 and 9 are 920 km s−1, based on 2009 FUSE data. Component 5 also exhibits a shift in velocity centroid. This is only the second known case of this behavior in a Seyfert galaxy. Due to the high quality of the HST/COS spectrum, we identify a previously undetected trough due to an excited state of Si ii for component 1. In combination with the resonance trough of Si ii and photoionization modeling, we directly determine the distance of the component 1 outflow to be 67.2 pc.

Abstract
We present a catalog of hard X-ray sources detected in the first 105 months of observations with the Burst Alert Telescope (BAT) coded-mask imager on board the Swift observatory. The 105-month Swift-BAT survey is a uniform hard X-ray all-sky survey with a sensitivity of

over 90% of the sky and

over 50% of the sky in the 14–195 keV band. The Swift-BAT 105-month catalog provides 1632 (422 new detections) hard X-ray sources in the 14–195 keV band above the

significance level. Adding to the previously known hard X-ray sources, 34% (144/422) of the new detections are identified as Seyfert active galactic nuclei (AGNs) in nearby galaxies (

). The majority of the remaining identified sources are X-ray binaries (7%, 31) and blazars/BL Lac objects (10%, 43). As part of this new edition of the Swift-BAT catalog, we release eight-channel spectra and monthly sampled light curves for each object in the online journal and at the Swift-BAT 105-month website.

Abstract
In this Letter, we report the monitoring of seasonal evolution near Titan’s poles. We find Titan’s south pole to exhibit since 2010 a strong temperature decrease and a dramatic enhancement of several trace species such as complex hydrocarbons and nitriles (HC3N and C6H6 in particular) previously only observed at high northern latitudes. This results from the seasonal change on Titan going from winter (2002) to summer (2017) in the north and, at the same time, the onset of winter in the south pole. During this transition period atmospheric components with longer chemical lifetimes linger in the north, undergoing slow photochemical destruction, while those with shorter lifetimes decrease and reappear in the south. An opposite effect was expected in the north, but not observed with certainty until now. We present here an analysis of high-resolution nadir spectra acquired by Cassini/Cassini Composite Infrared Spectrometer in the past years and describe the temperature and composition variations near Titan’s poles. From 2013 until 2016, the northern polar region has shown a temperature increase of 10 K, while the south has shown a more significant decrease (up to 25 K) in a similar period of time. While the south polar region has been continuously enhanced since about 2012, the chemical content in the north is finally showing a clear depletion for most molecules only since 2015. This is indicative of a non-symmetrical response to the seasons in Titan’s stratosphere that can set constraints on photochemical and GCM models.

Introduction
Tooth size, occlusal traits, and ethnicity are closely interrelated, and their impact on desirable orthodontic treatment outcome cannot be underestimated. This study was undertaken to assess the occlusal characteristics and ethnic variations in occlusion of Malaysian orthodontic patients and evaluate their correlation with Bolton’s tooth size discrepancy.

Materials and Methods
On 112 pretreatment study models of orthodontic patients, molar relationship, overjet, overbite, spacing, crowding, midline shift, and Bolton’s ratios were assessed. ANOVA, one-sample t-test, Chi-squared test, and Spearman’s rho correlation coefficient were used for statistical analysis.

Results
Significant difference between anterior ratio of our study and Bolton’s ideal values was found, for the entire study sample and Chinese ethnic group. Differences between races and malocclusion groups were not statistically significant (P > 0.05). Significant correlations were found as follows – in Angle’s Class I malocclusion between 1) anterior ratio and overbite, 2) overall ratio and maxillary crowding and spacing; in Angle’s Class II malocclusion between 1) anterior ratio and overjet and midline shift, 2) overall ratio and mandibular crowding; in Angle’s Class III malocclusion between 1) anterior ratio and mandibular crowding and both maxillary and mandibular spacing 2) overall ratio and mandibular crowding.

Conclusions
Significant differences in anterior ratio and Bolton’s ideal values for the Malaysian population were found, indicating variations in anterior tooth size as compared to Caucasians. Statistically significant correlations existed between Bolton’s ratios and occlusal traits. These findings can be applied clinically in diagnosis and treatment planning by keeping in mind the specific discrepancies that can occur in certain malocclusions and addressing them accordingly.
Orthodontic Clockwise Rotation of Maxillomandibular Complex for Improving Facial Profile in Late Teenagers with Class III Malocclusion: A Preliminary Report
Authors: Liou Eric J. W. , Wang Yu-Chi 
Published: February 2018

Objective
Orthodontic camouflage treatments improve occlusion but might worsen facial profile in patients with Class III malocclusion. It has been reported that surgical clockwise rotation of maxillomandibular complex (MMc) improves facial profile by reducing chin prominence and chin throat length in patients with Class III malocclusion. The purpose of this report was to illustrate two orthodontic techniques for clockwise rotation of the MMc in late teenagers with Class III malocclusion and preliminarily evaluate their clinical effects.

Patients and Methods
Six patients in late teenage with Class III malocclusion were included in this preliminary report. Bite raisers were first placed on the upper molars to open the bite and clockwise rotate the mandible. Intermaxillary elastics were then applied vertically between the upper and lower dentitions in 3 patients for bimaxillary extrusion (Technique-1) or between the upper dentition and the lower temporary anchorage devices (TADs) in another 3 patients (Technique-2) for upper dentition extrusion and closure of the anterior open bite. The three-dimensional cone-beam computed tomography images taken before and after orthodontic treatment were superimposed to evaluate the treatment effects of MMc clockwise rotation for both techniques.

Results
The Technique-1 extruded the upper and lower dentitions, rotated the mandible clockwise 2.01°, moved chin down 2.98 mm, and back −1.64 mm, although the mandible grew 2.47 mm during the treatment period. The Technique-2 extruded the upper dentition, rotated the mandible clockwise 0.90°, moved chin down 1.78 mm, but slightly forward 0.47 mm due to the mandible grew 2.50 mm and lower dentition was not extruded.

Conclusions
The orthodontic clockwise rotation of MMc is an effective technique for orthognathic camouflage. The applications of bite raisers and bimaxillary dentition extrusion could be more effective than single dentition extrusion with TADs in the mandible for clockwise rotation of MMc and improvement of occlusion and facial profile in late teenagers with Class III malocclusion. However, the comprehensive clinical effects and long-term stability need further clinical studies.
A Guide to Reading Herodotus’ Histories
Authors: Sheehan Sean 
Published: February 2018

Modern scholarship judges Herodotus to be a more complex writer than his past readers supposed. His Histories is now being read in ways that are seemingly incompatible if not contradictory. This volume interrogates the various ways the text of the Histories has been and can be read by scholars: as the seminal text of our Ur-historian, as ethnology, literary art and fable. Our readings can bring out various guises of Herodotus himself: an author with the eye of a travel writer and the mind of an investigative journalist; a globalist, enlightened but superstitious; a rambling storyteller but a prose stylist; the so-called ‘father of history’ but in antiquity also labelled the ‘father of lies’; both geographer and gossipmonger; both entertainer and an author whom social and cultural historians read and admire.
Guiding students chapter-by-chapter through approaches as fascinating and often surprising as the original itself, Sean Sheehan goes beyond conventional Herodotus introductions and instead looks at the various interpretations of the work, which themselves shed light on the original. With text boxes highlighting key topics and indices of passages, this volume is an essential guide for students whether reading Herodotus for the first time, or returning to revisit this crucial text for later research.

Published: February 2018

Abstract. The third edition of the international workshop Nonlinear Processes in Oceanic and Atmospheric Flows was held at the Institute of Mathematical Sciences (ICMAT) in Madrid from 6 to 8 July 2016. The event gathered oceanographers, atmospheric scientists, physicists, and applied mathematicians sharing a common interest in the nonlinear dynamics of geophysical fluid flows. The philosophy of this meeting was to bring together researchers from a variety of backgrounds into an environment that favoured a vigorous discussion of concepts across different disciplines. The present Special Issue on Current perspectives in modelling, monitoring, and predicting geophysical fluid dynamics contains selected contributions, mainly from attendants of the workshop, providing an updated perspective on modelling aspects of geophysical flows as well as issues on prediction and assimilation of observational data and novel tools for describing transport and mixing processes in these contexts. More details on these aspects are discussed in this preface.
Following the Money: Cathars, Apostolic Poverty, and the Economy in Languedoc, 1237–1259
Authors: Shulevitz Deborah 
Published: February 2018

Abstract
Voluntary poverty was an important element of the apostolic way of life embraced by many Christian religious groups in medieval Europe, both those considered heretical and others that were not. This article shows that the so-called Cathar heretics of Languedoc, however, did not embrace apostolic poverty. In fact, they participated actively in the local economy, even borrowing and lending money on occasion. Using testimony of Cathar supporters contained in thirteenth-century inquisition registers, this article shows that believers made large bequests and contributed both goods and money to the Cathars. These assets were held and managed collectively and used to support the heretical clergy and, at times, believers as well. The article also demonstrates the existence of a network of Cathar practitioners, believers, and supporters through which money was collected, held, and circulated.

Published: February 2018

Abstract. The incidence of HIV and AIDS in Indonesia continues to increase. The possibility of mother to child transmission will be greater if intervention is not performed. The purpose of this study is to assess the role of health systems in health and non-health sector affecting the implementation of PMTCT. This qualitative research took place in Jayawijaya. Primary data collection was conducted through in-depth interviews, and observation. Secondary data was derived from the survey of health facilities conducted in Papua. We interviewed eleven (11) informants. The results of this study confirmed that the implementation of PMTCT was still inadequate, only 64% of the health services in Jayawijaya provide PMTCT services. Considering the vast area and the difficulty of access to health services, local government should undertake expansion of comprehensive PMTCT services, provide antiretroviral drugs for pregnant women, and reagents, as well as psychosocial support to PLHIV. Keywords: HIV/AIDS, PMTCT, health system
Policy Implementation of Health Coverage for Indonesian Migrant Workers

Published: February 2018

Abstract. The purpose of this research is to analyze the policy implementation of health coverage for TKI. This research uses a qualitative method with in-depth interview. The framework of this research consists of the aspect of the advisable policy, the implementation factors, and the schematic representation of the problem by using SWOT. The result of this research is the health insurance owned by TKI comes from TKI insurance, the membership of JKN, and insurance during their employment abroad. TKI insurance policy is the instruction of Law No. 39 of 2004 which regulates the obligation of the ownership of the social security and or insurance policy for TKI. However, TKI insurance has not been involved with the social aspect because the agency commercializes the coverage of TKI and it is not included a social security. The change of consortium may have decreased the ratio of claim’s values to the annual premium which is attributable to the decreasing complaint cases from TKI. In the implementation, TKI insurance has been assisted by a lot of agencies. However, the bilateral cooperation related to the coordination of health coverage among countries has not been maximized. This research concludes that the coverage of health insurance for TKI is still lower (curative) and the government's attempt to integrate the social security for TKI is important. The researcher suggests the government should comprehensively implement the health coverage for TKI by incorporating the principle of promotion and prevention. Keywords: TKI Insurance, Consortium, Law No. 39 of 2004, SWOT, Bilateral Cooperation
Pulse Compression in Parametric Amplification
Authors: Diels Jean-Claude , Hsu Ning , Luo Xuan , Biegert Jens , Arissian Ladan 
Published: February 2018

AbstractThis article presents some of the phenomena associated with second‐order nonlinearities that can be exploited for pulse compression. This includes not only the optical pulse compression in second harmonic generation and parametric amplification, but also giant phase modulation leading to pulse compression in dispersive structures. The large bandwidth associated with ultrashort pulses and pulses with large phase modulation requires a theoretical treatment in the frequency domain, instead of considering the equations in the time domain with frequency‐dependent parameters. Our treatment in the frequency domain takes into account Sellmeier equations for the frequency dependence of the index of refraction, instead of a series expansion to first or second order. We also discuss applications in ultrashort pulse diagnostic and in predicting the autostabilization of optical parametric oscillators against cavity length fluctuations, by controlling the chirp of the pump and signal pulses.
