Published: September 2019

Abstract
Background Despite advances in natural language processing (NLP), extracting information from clinical text is expensive. Interactive tools that are capable of easing the construction, review, and revision of NLP models can reduce this cost and improve the utility of clinical reports for clinical and secondary use.
Objectives We present the design and implementation of an interactive NLP tool for identifying incidental findings in radiology reports, along with a user study evaluating the performance and usability of the tool.
Methods Expert reviewers provided gold standard annotations for 130 patient encounters (694 reports) at sentence, section, and report levels. We performed a user study with 15 physicians to evaluate the accuracy and usability of our tool. Participants reviewed encounters split into intervention (with predictions) and control conditions (no predictions). We measured changes in model performance, the time spent, and the number of user actions needed. The System Usability Scale (SUS) and an open-ended questionnaire were used to assess usability.
Results Starting from bootstrapped models trained on 6 patient encounters, we observed an average increase in F1 score from 0.31 to 0.75 for reports, from 0.32 to 0.68 for sections, and from 0.22 to 0.60 for sentences on a held-out test data set, over an hour-long study session. We found that tool helped significantly reduce the time spent in reviewing encounters (134.30 vs. 148.44 seconds in intervention and control, respectively), while maintaining overall quality of labels as measured against the gold standard. The tool was well received by the study participants with a very good overall SUS score of 78.67.
Conclusion The user study demonstrated successful use of the tool by physicians for identifying incidental findings. These results support the viability of adopting interactive NLP tools in clinical care settings for a wider range of clinical applications.

Abstract
Objectives Cranioorbital lesions present a great challenge for neurosurgeons and ophthalmologists. There is no consensus on the choice of surgical approach. The aims of this study were to investigate 49 cases of cranioorbital lesions and evaluate surgical approaches and outcomes.
Patients and Methods A retrospective study was done on 49 patients (51 operations) from 2009 to 2018. Information about the lesion was used to decide whether the supraorbital eyebrow approach (SEA) or pterional approach (PA) was performed.
Results Twenty-eight patients had surgical resection using SEA, 21 patients received PA, each group included one case of recurrence, who underwent reoperation via the same approach. SEA provided better cosmetic satisfaction, and a shorter incision than PA (p < 0.05). There was no significant difference in total resection rates, visual outcomes, recovery of ptosis, and other new surgical-related complications between SEA group and PA group (p > 0.05). Forty-nine cases of proptosis (94.1%, 49/51) were improved. Thirty-three patients (33/37, 89.2%) who underwent follow-up for longer than 12 weeks had a modified Rankin Scale (mRS) score ≤ 3.
Conclusion Surgery is the preferred treatment for cranioorbital lesions, but total resection is difficult. SEA may be a more minimally invasive option for some more limited lesions superior to optic nerve. PA may be more reasonable for the lesion with obvious hyperostosis and more extensive lesions.

Significance
Wildfires emit large amounts of biomass-burning (BB) aerosol particles and contribute to regional and global climate. Moreover, BB emissions are expected to increase in coming decades as a result of climate change. Tarballs, spherical organic BB particles, are estimated to contribute up to ∼30% of the BB aerosol mass. However, uncertainty still exists as to how tarballs form and how they influence climate. Our observations show that tarballs form through a combination of chemical and physical changes of primary organic aerosols within the first hours following emission. The finding of tarball formation will improve assessments of BB particle evolution and of BB impacts on regional and global climate.
Polymer effects modulate binding affinities in disordered proteins

Published: September 2019

Significance
The ability to form large interaction networks was one of the driving forces in the evolution of disordered proteins. However, their advantageous flexibility is accompanied by a tremendous solvent sensitivity that does not seem to have detrimental consequences. Our results provide a possible explanation of this conundrum. While individual interactions among 5 disordered proteins are extremely solvent sensitive, their competition for shared ligands in their natural network largely compensates this sensitivity. Recent ideas suggested the presence of a regulatory mechanism that compensates the solvent pliability of disordered proteins. Here, we identified a simple mechanism that achieves this task for networks of homologous disordered proteins.
Universal complementarity between coherence and intrinsic concurrence for two-qubit states

Published: September 2019

Abstract
Entanglement and coherence are two essential quantum resources for quantum information processing. A natural question arises of whether there is a direct link between them. In this work, we propose a definition of intrinsic concurrence for two-qubit states. Although the intrinsic concurrence is not a measure of entanglement, it embodies the concurrence of four pure states which are members of a special pure state ensemble for an arbitrary two-qubit state. And we show that intrinsic concurrence is always complementary to first-order coherence. In fact, this relation is an extension of the complementary relation satisfied by two-qubit pure states. Interestingly, we apply the complementary relation in some composite systems composed by a single-qubit state coupling with four typical noise channels respectively, and discover their mutual transformation relation between concurrence and first-order coherence. This universal complementarity provides reliable theoretical basis for the interconversion of the two important quantum resources.

Published: September 2019

Abstract
A Boundary Element Method (BEM) is used for obtaining solutions to anisotropic functionally graded media (FGM) boundary value problems (BVPs) governed by a Helmholtz type equation. A technique of transforming the variable coefficient governing equation to a constant coefficient equation is utilized for deriving a boundary integral equation. Some particular problems are considered to illustrate the application of the BEM. The results show the convergence, consistency, and accuracy of the BEM solutions.

Abstract
To present the geographical map of Dengue fever (DF) in Makassar city, Indonesia, we used the registered DF data to compute the relative risk (RR) of DF in different areas of Makassar city, Indonesia, for a five-year period (from 2012 to 2016). This paper aim to identify the the spatial distribution of DF occurrence to provide the map of risk area in Makassar City through the geographical map. To estimate RR for DF in Makassar City, Indonesia, the Besag York Mollie (BYM) model was proposed. The Bayesian estimates of DF relative risk were utilized for geographical mapping of DF. The results of the present study reveals that DF is still a serious health problem in Makassar city, Indonesia. The distribution of high and low risk areas of DF occurrences for all sub-districts in Makassar City can be identified in the risk geographical map to allow the better allocation and risk assessment.
Optimal harvesting of prey-predator fishery modeling in a two patch environment and harvesting in unprotected area
Authors: Toaha S , Kasbawati  
Published: September 2019

Abstract
This article deals with the dynamics of prey and predator populations in a two patch environment, a protected area and an unprotected area for fishing. The prey disperses between the two patches and migrates easily. There are two predators, one is in the protected area and another is in the unprotected area. The predators cannot migrate. Both prey and predator in unprotected area are harvested with constant efforts. The dynamical behavior of the populations is stated as a system of differential equations. The existence of a positive equilibrium point and its stability are investigated. We discuss the local stability of the positive equilibrium point. The stable equilibrium point is then associated with optimal harvesting problems. Based on the analysis, we found that there exist a stable positive equilibrium point when there is no harvesting. For model with constant efforts for both prey and predator, we found that over fishing will maximize the profit but the predator in the unprotected area will be extinct. With the help of Pontryagin’s maximum principle in maximizing the present value of revenues, we found the extremal of the efforts that maximize the present value of revenues. This means that both prey and predator in the protected area as well as the prey and predator in the unprotected area are possibly coexist although the prey and the predator in the unprotected area are harvested with constant efforts. Some numerical simulations area given to confirm the result of analysis.

Mineralogy and Geochemistry Variation of Igneous Rocks from Ungaran and Muria Volcano and Its Processes related to Subduction Zone Magmatism of Sunda Arc
Authors: Marin Jenian , Winarno Tri , Mindasari Dewi 
Published: September 2019

Abstract
Sunda Arc represent Quaternary magmatism as one of the most significantly active volcanic arc in Indonesia resulted from subduction of oceanic plate beneath continental plate. Along this subduction system, there are systematic variations in subduction angle, depth, crust thickness, and composition contribute to geochemical characteristic of igneous rocks along and across the arc. This study compared mineralogy and geochemistry characteristics from two volcanoes which represent across-arc variation. Petrographic analysis have been conducted on rocks’ thin section samples from Ungaran and Muria Volcano to characterize mineralogy of rocks. Selected samples were analyzed using X-Ray Fluorescence (XRF) for geochemistry of major and trace elements. Mineralogy of Ungaran rocks are dominated by plagioclase, clinopyroxene, and hornblende phenocrysts with composition range from andesite to basaltic andesite of high-K calc alkaline series. Samples from Muria Volcano are from alkaline series characterized by feldspathoid and alkali feldspar rich rocks with calcic plagioclase and pyroxene phenocrysts. This mineral assemblages, supported by major elements data suggest fractionation process in magma. Geochemical trend is systematically consistent with other island arc setting, where there is significant increase of total alkali from Ungaran to Muria. Trace element data shows decreasing in LILE/HFSE ratio further from arc. This suggests that Ungaran has more crustal and subducted slab influence, while Muria has higher degree of partial melting from deeper Benioff Zone.

Authors: Kurniasih A , Qadaryati N , Setyawan R 
Published: September 2019

Abstract
Kei Islands are known to have hydrocarbon potentials in shallow rock layers, trapped by folds and faults. This potential is characterized by the amount of gas seepage found in Kei Kecil, Kei Besar and Tayandu Island. The study was conducted in central and southern part of Kei Besar Island through outcrop observations and stratigraphic measurements aim to recognize the physical characteristics of rock. Kei Besar Island located in the easternmost part of Australian continental passive margin separated by the extension of Aru Through. Digital Elevation Model of Kei Besar Island shows that the northern part of research area has a steeper morphology than the southern. The stratigraphic characteristic in the central part of research area dominated by clastic limestone showing a shallowing-up stacking pattern. While in the southern part, the lithology dominated by coralline limestone contains many fragments of coral and large foraminifera. Stratigraphic analysis shows that lithology in the study area was formed in carbonate submarine fan which formed Elat Formation. This formation underlained by shallow carbonate rock which contain large foraminifera from Tamangil Formation. Tamangil Formation interfingered with lower part of Weduar Formation. Based on the analysis of surface data above, concluded that subsurface exploration is necessary to reconstruct the petroleum system in research area.

Published: September 2019

Abstract
Indonesia is located at an active tectonic zone, due to the encounter of three main slabs in the world: Eurasia, Pacific, and Indo-Australian slabs. This lead to high earthquake level in Indonesia, one of them is in Central Sulawesi. The research was conducted in order to identify the a value, b value, and seismicity using the Maximum Likelihood method. Earthquake data from the USGS catalog and BMKG were used from 1997 – 2017 with magnitude (M) ≥ 3 and depth (h) ≤ 1000 km, located at -30 S - 00 S and 1180 E – 1240 E. The result showed that highest seismicity is located at the Eastern part of Central Sulawesi. The Mc value of 5,2, a value ranges 5 – 11,5 indicates high seismic activity, b value ranges 0,6 – 1,8 indicates high level of rock fragility and rock resistance levels to low stress. The result in this study effectively to observe the seismicity which can be used as guided for earthquake mitigation.

Published: September 2019

Abstract
Prehistory of Central of South Sulawesi was a marine environment connecting Bone Bay and Makassar Strait through Tempe Lake. The influence of marine can be traced nowadays in outlet of Tempe Lake (Cenrana River). The concentration of SiO2 decreases toward downstream, on contrary Fe2O3 and CaO tend to increase downstream. Heavy mineral (Zr and TiO2) provides an increasing trend downstream . Most of the sediments originate from the rock covering the area and precipitation from the seawater. The latter can be found as far as 34 km from the coast of Bone Bay to the west.

Published: September 2019

Abstract
Multiple attenuation effect study in Lake Towuti seismic data is based on limited offset recording. The goal of this study is to better understand the sediments structure of Lake Towuti that layered above East Sulawesi ophiolitic and metamorphic rocks for stratigraphic interpretation. Surface-related multiple and internal multiple are a common noise signal that recorded in this seismic data, alongside the primary signal from the sediments layer. In order to get a representative subsurface image of the lake, a combination of some de-multiple method to suppress this noise signal has been applied in previous study. However, the line seismic that used in this seismic recording is less than 100 m. From our perspective, this limited offset line fact have to be considered carefully. It’s because some application of de-multiple method in this case will not effectively suppress the noise. In this study, we give an alternative combination method in function to put out the surface-related multiple of the case. First, we enhance the S/N ratio and velocity analysis of the data by Common Reflection Surface (CRS) method. From this enhancement, CRS can give a direct advantage when applying some de-multiple method, especially in Predictive Deconvolution and SRME method. Moreover, we combine the application of de-multiple theory with the strict arrangement of Predictive Deconvolution, Surface-Related Multiple Elimination (SRME), and the last is F-K filter. Those combination methods precisely give a better imaging of Lake Towuti sediments layer in this seismic processing study.
Derivative using complex variable conjugate approach for analytic signal of magnetic field anomaly due to 2D finite prism
Authors: Manan A , Hamimu L , Chahyani R 
Published: September 2019

Abstract
The complex variable conjugate approach has been derived analyticaly for derivative computation. Computational results are then used in calculating the amplitude of analytic signal. It is the square root of the square of the total magnetic field anomaly derivative. The total magnetic fields are generated by the upper and lower parts of a 2D finite prism, and subtraction of both parts yields the magnetic field anomaly. While the approach is obtained by truncating the Taylor series expansion of the total magnetic field function in argument of the complex conjugate in the h
2 order-term. Truncating the series does not significantly affect the computational results. This is because when step-size h get smaller, and at h≤10−2, then the errors due to the series truncation became 0 (K
p→0). For derivative computation, the approach has precision on the order of 10−17 to 10−12 towards analytical settlement. On the order of h≤10−2, the approach is insensitive to the selection of step-size h for small numbers, so it can be done arbitrarily without any particular treatment or requires a complicated combination of numbers. The computational results of the analytic signal amplitude show that the positive and negative polarity on the magnetic profile is transformed into a positive profile only. This can facilitate the interpretation of actual magnetic data, especially in determining the causative source position of anomalies.

Published: September 2019

Abstract
Fracture zones have always been areas of interest in mineral exploration. These geological structures are often studied and mapped as prospective zones for mineralization through the process of hydrothermal alteration. The transient electromagnetic (TEM) survey has been utilized to delineate the possible mineralized fracture zone of eastern Kuantan, Pahang. 35 single loop TEM soundings were acquired in a scattered manner over a region of high relief terrain, encompassing an area of approximately 5 km2. Data acquisition was conducted using the TerraTEM system by Monex Geoscope, with a 30 m x 30 m wire loop. The wire loop functions both as the transmitter coil and the receiver coil. The TEM responses indicate the presence of 3 electrically conductive zones (A, B and C) which are attributed to possible mineralized fracture regions within the country rock. All three regions record high conductivity readings with values of more than 15 mS/m and have a directional trend of NW-SE orientation. Target A is observed to be 300 m in width (E-W) and extends to 100 m in depth while B and C both have larger dimensions, exceeding 400 m in length (E-W) and up to depths of 150 m. The 3-D model generated from the 1-D soundings of the TEM dataset demonstrates the anomaly patterns that could be caused by the electrically conductive fracture zones within a resistive metasediment country rock. Geoelectrical properties of targets A, B and C may suggest the location of possible mineralized fracture zones within the study area.

Published: September 2019

Abstract
The swarm earthquake that occurred in West Halmahera which recorded a lot resulted in damage to houses in several rural areas. Although human casualties are not too significant, they affect the stability and capacity of an area in terms of regional development. Mapping of seismic hazard zone is a solution to minimize the impact that will be caused by the earthquake. The purpose of the study is to initial mapping seismic hazard zoning based on Horizontal Vertical to Spectral Ratio (HVSR) analysis. The estimated values of the fundamental frequency range from 0.0 Hz up to 4.9 Hz increases with decreasing depths of basement rock. Regions with the lowest dominant frequency value are South Ibu sub-District, this shows that the area has a large sediment thickness and is a vulnerable area of high. Amplification value range of 4.7 – 51, where the higher the amplification value, the thickness of sediments. The highest amplification value area is Jailolo sub-District and is an area that has a high risk of damage if shaken by an earthquake. This shows that areas that have high amplification values are areas that have the greatest potential for damage due to earthquakes. Analysis obtained from the results of the data shows that the topographic influence is also very significant with the earthquake waves that occur.
