Fiscal decentralization policies by giving greater authority to the regions to create efficiency and effectiveness to provide public goods, because the area is considered better understand the preferences of the community. Besides, fiscal decentralization policies can accelerate economic growth and changes in economic structure that has a devastating impact on the region is still considered backward. In general, backward areas still rely on primary sectors such districts/municipalities in Sulawesi, while the districts/municipalities in Java, relying on non-primary sector tends to be more advanced. Therefore, in general the economy is still underdeveloped Sulawesi compared to Java. The purpose of this research is to analyze the effect of fiscal decentralization on economic structural change districts/municipalities by comparing the two areas considered different economic structure, Sulawesi and Java. By using a panel analysis of data from 2001-2010 results showed that the fiscal decentralization policies has no effect on changes in the economic structure in Sulawesi. Java, while in the region shows that the negative effect of fiscal decentralization, it means diminishing the role of the primary sector, which leads to changes in the economic structure.

The purpose of this research is to analyze the influence of corporate governance mechanisms to the value of the firm through growth, profitability and dividend policy. The population of this study are all of manufacturing companies listed on the Indonesia Stock Exchange for the period of 2000-2012. The sampling method used in this study was purposive sampling, with the criteria that the company distributed cash dividends and have an independent member of the board of trustees. This study proves that the growth of the company affecting the profitability and the firmsvalue, despite the fact that the company reduced its dividend payments. Sobel’s test result shows that firm’s growth effect to firm value mediating by profitability significantly, represented by return on equity. Corporate governance mechanisms plays an important role in preventing unproductively growth of companies that have reached the stage of maturity. The intensification of the firms value, also influenced by its ability to increase the profitability and dividend payments. Institutional ownership and board size as a proxy for corporate governance mechanism plays an important part to encourage companies to improve their return on equity, while the independent board persuade companies to increase the dividend payments. In this study the board size variable has shown a very important role on the increase of profitability, dividend payments, and therealizations of the value of the company.

One of the challenging issues in poverty alleviation programs is to determine the set of multi criteria which encompass aspect of inputs, process and output that yield the best alternative program. This is important due to the fact that poverty is multidimensional issue and criteria to be considered in the program are vary. This study aimed to address a challenge by employing a mutli-criteria analysis. PROMETHEE was used to assess existing various poverty alleviation patterns. In addition, a new set of policy alternative, namely a hybrid policy was introduced in order to compare with existing policies. The results show that zakat patterns performs well in terms of time to eradicate poverty, the completeness of the program, accuracy of the target, recipient satisfactory, satisfactory of the admission process, data availability, and cost management. In contrast, CSR patterns perform well in management aspect, cost of management, data availability and satisfactory for the time of delivery program, while the pattern of government programs excel in aspects: the completeness of the program and the availability of funds. Overall, the newly introduced policy of hybrid program offers the best performance for all aspect of input, process and output in administering the poverty alleviation programs.

Abstract
Type Ibn supernovae (SNe) are a small yet intriguing class of explosions whose spectra are characterized by low-velocity helium emission lines with little to no evidence for hydrogen. The prevailing theory has been that these are the core-collapse explosions of very massive stars embedded in helium-rich circumstellar material (CSM). We report optical observations of six new SNe Ibn: PTF11rfh, PTF12ldy, iPTF14aki, iPTF15ul, SN 2015G, and iPTF15akq. This brings the sample size of such objects in the literature to 22. We also report new data, including a near-infrared spectrum, on the Type Ibn SN 2015U. In order to characterize the class as a whole, we analyze the photometric and spectroscopic properties of the full Type Ibn sample. We find that, despite the expectation that CSM interaction would generate a heterogeneous set of light curves, as seen in SNe IIn, most Type Ibn light curves are quite similar in shape, declining at rates around 0.1 mag day−1 during the first month after maximum light, with a few significant exceptions. Early spectra of SNe Ibn come in at least two varieties, one that shows narrow P Cygni lines and another dominated by broader emission lines, both around maximum light, which may be an indication of differences in the state of the progenitor system at the time of explosion. Alternatively, the spectral diversity could arise from viewing-angle effects or merely from a lack of early spectroscopic coverage. Together, the relative light curve homogeneity and narrow spectral features suggest that the CSM consists of a spatially confined shell of helium surrounded by a less dense extended wind.

Abstract
We present near-infrared spectra for 144 candidate planetary systems identified during Campaigns 1–7 of the NASA K2 Mission. The goal of the survey was to characterize planets orbiting low-mass stars, but our Infrared Telescope Facility/SpeX and Palomar/TripleSpec spectroscopic observations revealed that 49% of our targets were actually giant stars or hotter dwarfs reddened by interstellar extinction. For the 72 stars with spectra consistent with classification as cool dwarfs (spectral types K3–M4), we refined their stellar properties by applying empirical relations based on stars with interferometric radius measurements. Although our revised temperatures are generally consistent with those reported in the Ecliptic Plane Input Catalog (EPIC), our revised stellar radii are typically 0.13

(39%) larger than the EPIC values, which were based on model isochrones that have been shown to underestimate the radii of cool dwarfs. Our improved stellar characterizations will enable more efficient prioritization of K2 targets for follow-up studies.

Published: February 2017

Resumo
Este artigo é sobre o papel da Idade Média nos currículos escolares. Foram consideradas duas versões da BNCC: a publicada em 2015 e a publicada em 2016. A partir da concepção que a aprendizagem histórica se dá também pela via do estranhamento, e considerando a “medievalística”, “medievalidade” e “reminiscências medievais”, problematiza-se o ensino de História da Idade Média no Brasil, a partir de algumas entradas. Entradas são oportunidades de inserções temáticas do medievo no contexto escolar: discursos midiáticos sobre o islã, diferenças entre Ocidente e Oriente e residualidades. Conclui-se que pode haver espaço para a Idade Média na Base desde que ampliada a compreensão do ensino de História para além dos “usos do passado”. Considera-se o ensino de Idade Média uma etapa importante na escolarização básica que pode favorecer a crítica e a compreensão das apropriações feitas do medievo.

Fast Linearized Augmented Lagrangian Method for Euler's Elastica Model
Authors: Zhang Jun , Chen Rongliang , Deng Chengzhi , Wang Shengqian 
Published: February 2017

AbstractRecently, many variational models involving high order derivatives have been widely used in image processing, because they can reduce staircase effects during noise elimination. However, it is very challenging to construct efficient algorithms to obtain the minimizers of original high order functionals. In this paper, we propose a new linearized augmented Lagrangian method for Euler's elastica image denoising model. We detail the procedures of finding the saddle-points of the augmented Lagrangian functional. Instead of solving associated linear systems by FFT or linear iterative methods (e.g., the Gauss-Seidel method), we adopt a linearized strategy to get an iteration sequence so as to reduce computational cost. In addition, we give some simple complexity analysis for the proposed method. Experimental results with comparison to the previous method are supplied to demonstrate the efficiency of the proposed method, and indicate that such a linearized augmented Lagrangian method is more suitable to deal with large-sized images.
Total Variation Based Parameter-Free Model for Impulse Noise Removal
Authors: Sciacchitano Federica , Dong Yiqiu , Andersen Martin S. 
Published: February 2017

AbstractWe propose a new two-phase method for reconstruction of blurred images corrupted by impulse noise. In the first phase, we use a noise detector to identify the pixels that are contaminated by noise, and then, in the second phase, we reconstruct the noisy pixels by solving an equality constrained total variation minimization problem that preserves the exact values of the noise-free pixels. For images that are only corrupted by impulse noise (i.e., not blurred) we apply the semismooth Newton's method to a reduced problem, and if the images are also blurred, we solve the equality constrained reconstruction problem using a first-order primal-dual algorithm. The proposed model improves the computational efficiency (in the denoising case) and has the advantage of being regularization parameter-free. Our numerical results suggest that the method is competitive in terms of its restoration capabilities with respect to the other two-phase methods.

Abstract. In many agricultural regions, the human use of water for irrigation is often ignored or poorly represented in land surface models (LSMs) and operational forecasts. Because irrigation increases soil moisture, feedback on the surface energy balance, rainfall recycling, and atmospheric dynamics is not represented and may lead to reduced model skill. In this work, we describe four plausible and relatively simple irrigation routines that can be coupled to the next generation of hyper-resolution LSMs operating at scales of 1 km or less. The irrigation output from the four routines (crop model, precipitation delayed, evapotranspiration replacement, and vadose zone model) is compared against a historical field-scale irrigation database (2008–2014) from a 35 km2 study area under maize production and center pivot irrigation in western Nebraska (USA). We find that the most yield-conservative irrigation routine (crop model) produces seasonal totals of irrigation that compare well against the observed irrigation amounts across a range of wet and dry years but with a low bias of 80 mm yr−1. The most aggressive irrigation saving routine (vadose zone model) indicates a potential irrigation savings of 120 mm yr−1 and yield losses of less than 3 % against the crop model benchmark and historical averages. The results of the various irrigation routines and associated yield penalties will be valuable for future consideration by local water managers to be informed about the potential value of irrigation saving technologies and irrigation practices. Moreover, the routines offer the hyper-resolution LSM community a range of irrigation routines to better constrain irrigation decision-making at critical temporal (daily) and spatial scales (< 1 km).
On the consistency of scale among experiments, theory, and simulation

Published: February 2017

Abstract. As a tool for addressing problems of scale, we consider an evolving approach known as the thermodynamically constrained averaging theory (TCAT), which has broad applicability to hydrology. We consider the case of modeling of two-fluid-phase flow in porous media, and we focus on issues of scale as they relate to various measures of pressure, capillary pressure, and state equations needed to produce solvable models. We apply TCAT to perform physics-based data assimilation to understand how the internal behavior influences the macroscale state of two-fluid porous medium systems. A microfluidic experimental method and a lattice Boltzmann simulation method are used to examine a key deficiency associated with standard approaches. In a hydrologic process such as evaporation, the water content will ultimately be reduced below the irreducible wetting-phase saturation determined from experiments. This is problematic since the derived closure relationships cannot predict the associated capillary pressures for these states. We demonstrate that the irreducible wetting-phase saturation is an artifact of the experimental design, caused by the fact that the boundary pressure difference does not approximate the true capillary pressure. Using averaging methods, we compute the true capillary pressure for fluid configurations at and below the irreducible wetting-phase saturation. Results of our analysis include a state function for the capillary pressure expressed as a function of fluid saturation and interfacial area.

Chemotherapy induces tumor immune evasion by upregulation of programmed cell death ligand 1 expression in bone marrow stromal cells

Published: February 2017

Programmed cell death ligand 1 (PD‐L1) is a negative regulator of the immune response that enables tumor cells to escape T‐cell immunity. Although PD‐L1 expression in cancer cells has been extensively studied, the expression of PD‐L1 in stromal cells and its clinical significance remain largely unknown. Here, we show that bone marrow stromal cells express a low level of PD‐L1 and that this molecule is significantly upregulated by key drugs used in the treatment of lymphoma at clinically relevant concentrations. Mechanistically, chemotherapeutic drugs induce PD‐L1 expression in stromal cells through upregulation of granulocyte macrophage colony‐stimulating factor and activation of the extracellular signal‐regulated kinase (ERK) 1/2 signaling pathway. Suppression of ERK by a chemical inhibitor or genetic silencing of ERK2 expression prevents drug‐induced PD‐L1 expression. PD‐L1 expression is upregulated in the bone marrow stromal cells of mice treated with doxorubicin and in drug‐treated bone marrow specimens from lymphoma patients. Drug‐induced PD‐L1 expression in stromal cells can cause significant impairment of T‐cell functions. Overall, our study reveals a previously unrecognized mechanism by which chemotherapy induces tumor immune evasion by upregulation of PD‐L1 in bone marrow stromal cells, and provides new evidence for the combination of chemotherapy and anti‐PD‐L1/PD‐1 as an effective strategy for treatment of lymphoma and other cancers.
Long‐term and seasonal Caspian Sea level change from satellite gravity and altimeter measurements

Published: February 2017

AbstractWe examine recent Caspian Sea level change by using both satellite radar altimetry and satellite gravity data. The altimetry record for 2002–2015 shows a declining level at a rate that is approximately 20 times greater than the rate of global sea level rise. Seasonal fluctuations are also much larger than in the world oceans. With a clearly defined geographic region and dominant signal magnitude, variations in the sea level and associated mass changes provide an excellent way to compare various approaches for processing satellite gravity data. An altimeter time series derived from several successive satellite missions is compared with mass measurements inferred from Gravity Recovery and Climate Experiment (GRACE) data in the form of both spherical harmonic (SH) and mass concentration (mascon) solutions. After correcting for spatial leakage in GRACE SH estimates by constrained forward modeling and accounting for steric and terrestrial water processes, GRACE and altimeter observations are in complete agreement at seasonal and longer time scales, including linear trends. This demonstrates that removal of spatial leakage error in GRACE SH estimates is both possible and critical to improving their accuracy and spatial resolution. Excellent agreement between GRACE and altimeter estimates also provides confirmation of steric Caspian Sea level change estimates. GRACE mascon estimates (both the Jet Propulsion Laboratory (JPL) coastline resolution improvement version 2 solution and the Center for Space Research (CSR) regularized) are also affected by leakage error. After leakage corrections, both JPL and CSR mascon solutions also agree well with altimeter observations. However, accurate quantification of leakage bias in GRACE mascon solutions is a more challenging problem.
