Published: June 2018

AbstractCurrent clinical methods of screening older adults for fall risk have difficulties. We analyzed data on 67 women (mean age = 77.5 years) who participated in the Objective Physical Activity and Cardiovascular Health (OPACH) study within the Women’s Health Initiative and in an accelerometer calibration substudy. Participants completed the short physical performance battery (SPPB), questions about falls in the past year, and a timed 400-m walk while wearing a hip triaxial accelerometer (30 Hz). Women with SPPB ≤ 9 and 1+reported falls (n = 19) were grouped as high fall risk; women with SPPB = 10–12 and 0 reported falls (n = 48) were grouped as low fall risk. Random Forests were trained to classify women into these groups, based upon traditional measures of gait and/or signal-based features extracted from accelerometer data. Eleven models investigated combined feature effects on classification accuracy, using 10-fold cross-validation. The models had an average 73.7% accuracy, 81.1% precision, and 0.706 AUC. The best performing model including triaxial data, cross-correlations, and traditional measures of gait had 78.9% accuracy, 84.4% precision, and 0.846 AUC. Mediolateral signal-based measures—coefficient of variance, cross-correlation with anteroposterior accelerations, and mean acceleration—ranked as the top 3 features. The classification accuracy is promising, given research on probabilistic models of falls indicates accuracies ≥80% are challenging to achieve. The results suggest accelerometer-based measures captured during walking are potentially useful in screening older women for fall risk. We are applying algorithms developed in this paper on an OPACH dataset of 5000 women with a 1-year prospective falls log and week-long, free-living accelerometer data.

AbstractWildlife populations are under intense anthropogenic pressures, with the geographic range of many species shrinking, dramatic reductions in population numbers and undisturbed habitats, and biodiversity loss. It is postulated that we are in the midst of a sixth (Anthropocene) mass extinction event, the first to be induced by human activity. Further, threatening vulnerable species is the increased rate of emerging diseases, another consequence of anthropogenic activities. Innovative approaches are required to help maintain healthy populations until the chronic underlying causes of these issues can be addressed. Fibropapillomatosis in sea turtles is one such wildlife disease. Here, we applied precision-medicine-based approaches to profile fibropapillomatosis tumors to better understand their biology, identify novel therapeutics, and gain insights into viral and environmental triggers for fibropapillomatosis. We show that fibropapillomatosis tumors share genetic vulnerabilities with human cancer types, revealing that they are amenable to treatment with human anti-cancer therapeutics.

Published: June 2018

Purpose
Designing augmentative and alternative communication (AAC) displays that minimize operational demands is an important aspect of AAC intervention. The current study compared the effect of 2 display designs on the speed of locating target words by preschoolers without disabilities.

Method

Across 5 sessions, participants in the consistent condition (
n
= 12) were asked to locate symbols on arrays that did not change, whereas participants in the variable condition (
n
= 12) utilized arrays where the symbols changed locations each session.

Results
No difference in response time across conditions was noted during the 1st session; however, by the 5th session, participants in the consistent condition demonstrated significantly faster response times than participants in the variable condition.

Conclusions
The current study illustrated an advantage of consistent symbol location for preschoolers without disabilities. Clinical applications for incorporating consistent symbol location into AAC display design are discussed; however, replication with children who use AAC is critical.
Wideband CP magnetoelectric dipole antenna with microstrip line aperture‐coupled excitation
Authors: Cui Xuewu , Yang Feng , Gao Min 
Published: June 2018

A novel wideband circularly polarised (CP) magnetoelectric dipole antenna, which is excited by microstrip line aperture‐coupled feeding structure, is proposed and investigated. The wide impedance bandwidth and broadband CP characteristic are achieved based on the simple feeding structure. An antenna prototype is fabricated and exemplified to validate the proposed concept. Measured results show that the proposed antenna achieves an impedance bandwidth of 65% for voltage standing wave ratio <2 from 2.97 to 5.85 GHz, the broadside maximum gain is up to 10.2 dBi. Moreover, the 3 dB axial ratio bandwidth is about 75%, ranging from 2.7 to 5.8 GHz. Stable and symmetric unidirectional radiation patterns with low backward radiations are obtained over the operating band.
High step‐up DC–DC converter with low power device voltage stress for a distributed generation system
Authors: Ai Jian , Lin Mingyao 
Published: June 2018

This study presents a novel step‐up DC–DC converter with the coupled inductor and low switch voltage stress, which reduce diode voltage stress. The presented converter contains single switch, four diodes, four capacitors and one coupled inductor. When switch is turned ON, the primary side of coupled inductor is charged by the input source. Besides, the primary and secondary side of the coupled inductor is discharged in series with the input source and two capacitors to realise the high step‐up voltage gain when the switch is turned OFF. Furthermore, the clamped circuit which adopts two capacitors negative pole connection not only recycles leakage energy and obtains the high voltage conversion gain, but also is realised to reduce the voltage stress of the diode, which can be use low‐voltage rated devices with low on‐resistance. In addition, the three diodes are working on the zero‐current‐switching turn‐off, therefore, the loss is reduced and the reverse‐recovery problem is avoided. The current falling rate of the output diode is effectively restricted for the leakage inductor, therefore, its reverse‐recovery problem is effectively alleviated. Finally, a 40 V input voltage, 380 V output voltage and 400 W output power prototype circuit is established in the laboratory to verify the performance.
Dorsal Failures: From Saddle Deformity to Pollybeak
Authors: Hamilton Grant 
Published: June 2018

AbstractThe nasal dorsum is an important component of a rhinoplasty and may be the primary motivation for seeking surgery. The nasal dorsum is a complex three-dimensional shape that is shrouded by local anesthetic and edema during surgery. This makes an accurate assessment of the surgical changes challenging. Complications related to dorsal modification include imbalances from over- or underresection of the structures of the nasal dorsum, inadequate or overaugmentation, an open-roof deformity, pollybeak, saddle nose, inverted-V, warped cartilage, visible grafts, contour problems, graft malposition, and extrusion. This review will discuss the common problems that can occur with dorsal modification during rhinoplasty.
Functional Compromise in the Middle Vault in the Management of Revision Rhinoplasty
Authors: Friedman Oren , Wang Leo 
Published: June 2018

AbstractAs rhinoplasty procedures become more common, the need for revision surgeries increases as well. Unlike primary rhinoplasties, revision rhinoplasties can be more challenging because of anatomic differences from initial surgery, a lack of available cartilage, tissue remodeling responses, and other complications. As such, surgeons should be prepared to address revision rhinoplasty patients differently from primary rhinoplasty patients. Here, the authors describe a generalizable approach to revision functional rhinoplasty patients and detail some of the surgical techniques that can be employed to achieve optimal outcomes, with particular attention paid to procedures that can be used in the middle vault.

Abstract
Introduction There are more than 1,500 hospital procedures included in the Brazilian Unified Healthcare System's (SUS, in the Portuguese acronym) table, which is the reference for service payment provided by establishments serving the public health network, and they are stagnant. The underfinancing of procedures is so dramatic that in some cases the amounts paid by the SUS are even lower than the taxes generated by the costs of the same procedures in Brazilian private hospitals. This article aims to compare the evolution of the compensation of neurosurgical procedures by calculating the percentile of the lag in the values transferred to both neurosurgeons and hospitals, according to the SUS table, establishing the ideal and real values according to the current inflation, in a retrospective 9-year comparison.
Methodology This is an observational, comparative, retrospective study, based on the values of medical and hospital money transfers of 25 neurosurgical procedures in 2008, which were corrected according to the 2017 National Consumer Price Index (IPCA, in the Portuguese acronym).
Results Through this study, from 2008 to 2017, the transfers of medical fees regarding neurosurgical techniques are almost completely outdated. As examples, we can mention: the external/subgaleal ventricular shunt, with a deficit of 43.6%; the electrode implant for brain stimulation, with - 41.67%; and decompressive craniotomy, with - 32.21% in relation to the corrected value. Only 4 of the 25 neurosurgeries present a value above that predicted by the IPCA, one of them being cerebral aneurysm embolization larger than 1.5 cm with a narrow neck (+ 8.0%). Regarding the money transfers to hospitals, all procedures are 43.6% lower than expected, since there was no readjustment in the amounts paid to the institutions in the analyzed period. For example, in 2008, for the transposition of the cubital nerve, R$ 267.30 were transferred, and the same amount was maintained in 2017; and, for the surgical treatment of compressive syndrome in osteofibrous tunnel at carpal level (R$ 145.18), the amount also remained fixed throughout these 9 years.
Conclusion Because they did not follow the evolution of the economy, in 80% of the surgeries, the neurosurgeons did not have their economic demands met regarding the procedures performed through SUS. And the data became even more alarming when the money transfers to hospitals were evaluated, since there was no evolution in the money transfers for any of the neurosurgeries evaluated.
Druckschmerzhafte Körperstellen – Enthesitis?
Authors: Haibel H. 
Published: June 2018

ZusammenfassungDie Enthesitis ist eine häufige Manifestation bei Spondyloarthritiden (SpA) und Psoriasis- Arthritis (PsA) und tritt bei bis zu 40 % der Patienten mit SpA auf. Wegen ihrer pathognomonischen Bedeutung ist Enthesitis in verschiedenen Klassifikationskriterien für SpA und PsA als ein Eingangs- oder Nebenkriterium aufgenommen worden. Häufigste Lokalisation ist die Ferse, aber Enthesitiden können ubiquitär an Sehnenansätzen in den Knochen auftreten. Bei der Diagnose der Enthesitis sind zahlreiche Differenzialdiagnosen zu beachten, insbesondere sollten mechanisch-degenerative Ursachen unterschieden und eine Fibromyalgie ausgeschlossen werden. Als bildgebende Verfahren sind der Power Doppler Ultraschall (PDUS) und die Magnetresonanztomografie (MRT) besonders diagnostisch hilfreich. Die therapeutischen Optionen bei Enthesitis sind begrenzt. Es werden die Gabe von nichtsteroidalen Antirheumatika und lokale Steroidinjektionen empfohlen. Während in kleineren Studien für Disease Modifying Antirheumatic Drugs keine Wirksamkeit gezeigt werden konnte, haben sich TNF-alpha-Blocker, Anti-IL-17-, Anti-IL-12/23- sowie Anti-IL-23-Antikörper in randomisierten kontrollierten Studien sowohl bei SpA als auch/oder bei PsA als effektiv erwiesen. Sie sind jedoch derzeit nicht für die Therapie einer alleinig vorliegenden Enthesitis zugelassen.

Abstract
Agriculture has long become a prime sector for regional development in Buton Island, although local government emphasis on perennial crops. Food crop have been developed in very limited land areas, mainly on transmigration areas, as parts of central government programs. Today, the central government has launched a national strategic program on food self-sufficiency and has imposed the local government to optimize available land for cultivating food crop. The primary aim of study is to develop rapid assessment on a spatial basis using GIS for agricultural land suitability evaluation of agriculture commodities, i.e., rice (irrigated paddy field, rainfed rice) and corn (Zea maize L.). The study was undertaken using the following procedures: (i) conducting reconnaissance soil survey based on land units; (ii) constructing soil database in a GIS; and (iii) classifying land suitability using the FAO method. Spatial data were generated from digital topographic map, soil survey, soil characteristics, as well as climate data. Preliminary results indicate that quite large area available for food crop cultivation both in the context of land suitability (mostly in S2 and S3 classes) and land availability. All data bases were managed in GIS, then it is amenable to various operations in GIS to accommodate possible additional assessment including socio-economic and policy assessment.

Abstract
Urban ecology has become a more popular concern as the awareness for mutual sharing between humans and other ecosystem members is increasing. This study aimed at assessing the value of urban farms in the city of Makassar, a fast-developing Indonesian city which according to its city council classification covered significant area of the city. The research employed Rapid Biodiversity Assessment (RBA) to assess quality of urban farms. The method assessed two important aspects of spaces in terms of ecology i.e. vegetation structures and vascular plants. Results showed the biodiversity of urban farms in Makassar compared to other typologies was high. Urban farms in Makassar in general have potential for ecological spots because despite they are more cultural than natural, their high plant biodiversity score, dominance of trees and less built areas make them always available for improvement to become more ecological spots.

Abstract
Endophytic fungi are one of the agents to control phytopathogen both bacterial or fungi including dieback disease on cacao such as Vascular Streak Dieback (VSD). Ten fungal isolates that associated with a healthy branch of VSD resistant clone was applied to cacao seedling, the fungi were a Curvularia-like colony, a Fusarium-like colony, a Geotrichum-like colony, an Aspergillus-like colony, a Gliocladium-like colony, a Colletotrichum-like colony and four isolates indicates as mycelia sterilia fungi. Those fungi were applied at 2.5-old months cacao seedling of moderate to susceptible clone against VSD, and 30 days after inoculation of those fungi, the seedling was applied with a bunch of mycelia emerged from infected branch that mix with water using mixer appliance and then the seedling was exposed at open area surrounded by infested cacao tree. The disease incidence was recorded started at 30 and then 60, 90 and 120 days after inoculation of the pathogen and exposed. The result of study shows that the disease appeared increasing gradually and 120 days fungus Curvularia-like colony exhibited lower incidence followed by Copper fungicide, Mycelia sterilia 1, Gliocladium-like colony, Fusarium-like colony, Geotrichum-like colony, Mycelia sterilia 3, Colletotrichum-like colony, Aspergillus-like colony, control (no application), Mycelia sterilia 2, Mycelia sterilia 4 with percentage of 3.0, 8.3, 9.5, 11.3, 15.8, 18.0, 19.0, 19.3, 21.3, 26.5, 30.5, respectively. The result indicates that some fungi associated with VSD resistant clone were able to prevent VSD to develop and causing symptoms.

Abstract
One of the crucial issues in developing country is land conflict. It occured since 1978 and still unsolved. This research aimed to investigate and analyze (1) the social and cultural values of Makassarese Women (2) the impact of the land conflict on Makassarese Women, (3) the strategy of female farmers in facing land conflict. The research was conducted in the villages of Timbuseng and Kampung Beru, North Polongbangkeng Sub-District, Takalar Regency, Indonesia. The research employed qualitative method combined with ethnography case study with in-depth interviews, observation, document study, and focus group discussion (FGD). The results indicate that the land conflict happened in North Polongbangkeng Sub-District had an impact on the socio-economic and cultural life of the community. The women had to play a role and the same position as the man in productive, social and domestic matters. For 25 years, the community had to avoid and wait. Since 2007, the community had thought that the contact with PTPN XIV land had ended and the community could take over the land they owned. The strategy done by women was to join the man in their fight to get back their land. They started with confronting actions to forming an organization called Polongbangkeng Farmers Unity. In 2014 the partnership program was established as an effort to settle the land conflict, though until now this program had not answered the primary needs of the community in the region.
Optimal projection methods for model order reduction of discrete-time systems
Authors: Ibrir Salim 
Published: June 2018

AbstractNumerical algorithms are developed for model order reduction of discrete-time systems using both optimal projection and $H_2$-norm minimization. The state-space matrices of the reduced-order system are obtained via the solution of a convex optimization problem. Subsequently, the results are exploited for the design of non-linear reduced-order systems verifying the input-to-state stability property. Proofs of stability and error approximation bounds are provided along with numerical simulations to highlight the strengths and the validity of the theoretical results.
Black hole spin from wobbling and rotation of the M87 jet and a sign of a magnetically arrested disc
Authors: Sob’yanin (Денис Николаевич Собьянин) Denis Nikolaevich 
Published: June 2018

ABSTRACT
New long-term Very Long Baseline Array observations of the well-known jet in the M87 radio galaxy at 43 GHz show that the jet experiences a sideways shift with an approximately 8–10 yr quasi-periodicity. Such jet wobbling can be indicative of a relativistic Lense–Thirring precession resulting from a tilted accretion disc. The wobbling period together with up-to-date kinematic data on jet rotation opens up the possibility for estimating angular momentum of the central supermassive black hole. In the case of a test-particle precession, the specific angular momentum is J/Mc = (2.7 ± 1.5) × 1014 cm, implying moderate dimensionless spin parameters a = 0.5 ± 0.3 and 0.31 ± 0.17 for controversial gas-dynamic and stellar-dynamic black hole masses. However, in the case of a solid-body-like precession, the spin parameter is much smaller for both masses, 0.15 ± 0.05. Rejecting this value on the basis of other independent spin estimations requires the existence of a magnetically arrested disc in M87.

ABSTRACT
We present nebular-phase spectra of the Type Ia supernova (SN Ia) 2016brx, a member of the 1991bg-like subclass that lies at the faint end of the SN Ia luminosity function. Nebular spectra are available for only three other 1991bg-like SNe, and their Co line centres are all within ≲500 km s−1 of each other. In contrast, the nebular Co line centre of SN 2016brx is blue-shifted by &gt;1500 km s−1 compared to them and by ≈1200 km s−1 compared to the rest frame. This is a significant shift relative to the narrow nebular line velocity dispersion of ≲2000 km s−1 of these SNe. The large range of nebular line shifts implies that the 56Ni in the ejecta of SN 1991bg-like events is off-centre by ∼1000 km s−1 rather than universally centrally confined as previously suggested. With the addition of SN 2016brx, the Co nebular line shapes of 1991bg-like objects appear to connect with the brighter SNe Ia that show double-peaked profiles, hinting at a continuous distribution of line profiles among SNe Ia. One class of models to produce both off-centre and bimodal 56Ni distributions is collisions of white dwarfs with unequal and equal masses.
