An End-to-End Learnable Flow Regularized Model for Brain Tumor Segmentation

Many segmentation tasks for biomedical images can be modeled as the minimization of an energy function and solved by a class of max-flow and min-cut optimization algorithms. However, the segmentation accuracy is sensitive to the contrasting of semantic features of different segmenting objects, as the traditional energy function usually uses hand-crafted features in their energy functions. To address these limitations, we propose to incorporate end-to-end trainable neural network features into the energy functions. Our deep neural network features are extracted from the down-sampling and up-sampling layers with skip-connections of a U-net. In the inference stage, the learned features are fed into the energy functions. And the segmentations are solved in a primal-dual form by ADMM solvers. In the training stage, we train our neural networks by optimizing the energy function in the primal form with regularizations on the min-cut and flow-conservation functions, which are derived from the optimal conditions in the dual form. We evaluate our methods, both qualitatively and quantitatively, in a brain tumor segmentation task. As the energy minimization model achieves a balance on sensitivity and smooth boundaries, we would show how our segmentation contours evolve actively through iterations as ensemble references for doctor diagnosis.
Linear codes from vectorial Boolean functions in the context of algebraic attacks

In this paper, we study the relationship between vectorial (Boolean) functions and cyclic codes in the context of algebraic attacks. We first derive a direct link between the annihilators of a vectorial function (in univariate form) and certain [Formula: see text]-ary cyclic codes (which we show that they are LCD codes). We also present some properties of those cyclic codes as well as their weight enumerator. In addition, we generalize the so-called algebraic complement and study its properties.
Particle Swarm Optimization Based on Punctuated-equilibrium Model

This paper presents a modified particle swarm optimization, named as punctuated-equilibrium particle swarm optimization (PEPSO). This method refers to punctuated-equilibrium Model (PEM) which is a pattern of group development in organizational behavior. PEM uses the long-term equilibrium phase and the short-term abrupt phase to solve the problem of group stagnation. The present work mathematically modelled this alternating process. The efficiency of the proposed PEPSO was evaluated using CEC 2014 benchmark functions. The experiments showed that PEPSO could solve premature convergence and had more good convergence accuracy than PSO on some test functions. Furthermore, it was also confirmed that the swarm was divided into different groups and the individuals of every group almost acted in unison. This provides a good explanation between PSO and organizational behavior from a new experimental perspective.
Zone Specific Index Based Model for Data Storage Identification in Search Query Processing

In this paper, zone-specific index based model has been designed to store web pages collected from registered web site and processing of search queries placed at search engine. Identification of relevant web page is accomplished through matching of keywords in search query and web pages. Another key issue of search query processing is response time. It is always desirable that minimum delay in response time to processing of a search query. Response time of search query is dependent on network framework used and indexing mechanism to identify data storage among several available data repository to identify web pages. In proposed model, distribution of web pages among data storage systems is accomplished through matching of keywords presence in each web page to related keywords of zones. Each web page is stored in data storage systems through identification of zones. Search query is processed through zone identification using matching of keywords presence in each search query to related keywords of zones. Presence of specific keywords in web page and search query helps for speedy identification of specific zones as well as identification of data storage systems. Organization of web pages among data storage systems using zone-specific index based mechanism improves response time and accuracy for processing of search queries.
Information Communication Guiding Model of Online Social Education of Rural Children in Chongqing Based on Data Dynamics and Mining

Information communication guiding model of the online social education of rural children in Chongqing based on data dynamics and mining is designed in this manuscript. At present, the dynamic evolution methods of distributed software systems implemented from the perspective of the model-driven, control engineering, software architecture, etc. Hence, this paper has the 2 aspects of novelties. (1) Users of social networks have their own attitudes towards various types of messages, that is, they tend to spread the positive or negative degree of the message. (2) Dijkstra algorithm based on the shortest path of the static graph is modified to enable it to calculate the minimum delay path. The experimental results have proven the performance. In the future, we will apply the proposed method into more places.

본 연구는 주택시장을 이해하기 위한 시계열적 연구에 있어 다른 부동산 유형과의 관계 속에서 주택시장의 변화 특성을 찾기 위한 목적으로 진행되었다. 이를 위해 부동산 유형별 종류 및 특성, 서울시 권역별 부동산 유형별 특성, 주택하위시장 이론 및 관련 선행연구를 고찰하여 연구의 차별성 및 연구의 방향성을 찾았다. 분석자료는 부동산 114Reps의 데이터를 활용하여 서울시 4개 권역별로 아파트, 오피스텔, 집합상가에 대한 2006년 1분기~2019년 2분기까지 매매가격에 대한 시계열데이터를 구축한 뒤 지수화하여 실증분석을 진행하였다. 본 연구에 나타난 부동산 유형별 가격 간의 상관관계에 대한 실증분석의 주요 결과는 다음과 같다. 첫째, 부동산 유형별 가격 간 인과관계는 권역별 특성에 따라 원인변수와 결과변수에 차이가 존재하였다. 둘째, 부동산 유형별 가격 간 상관관계에 있어 권역별 특성에 따라 정(+)과 부(-) 관계가 나타났다. 셋째, 부동산 유형별 가격 간 영향관계에 있어 아파트, 오피스텔, 집합상가의 단기간 내 상호 영향력은 크지 않은 것으로 나타났다. 실증분석 결과, 부동산 유형별 가격 간 상호관계에 있어서 권역별 시장 상황 및 특성에 따라 인과관계 및 상관관계에 차이가 있음과 투자수요의 움직임에 따라 부동산 유형별 가격 변동에 대한 영향관계가 다르게 나타날 수 있음을 확인하였다.This study was conducted with the aim of finding the characteristics of changes in the housing market in relation to other types of real estate in a time series study to understand the housing market. To this end, we looked into the types and characteristics of each type of real estate, the characteristics of each type of real estate in Seoul, the housing sub-market theory, and related prior research to find the differentiation of research and direction of research. Using the data of real estate 114Reps, time series data on selling prices were established between Q1 2006 and Q2019 for apartment, officetels, and collective commercial stores in each of the four districts of Seoul, and the empirical analysis was conducted by indexing them. The main results of the empirical analysis of the interrelationships between prices by type of real estate shown in this study are as follows : First, the causal relationship between prices by type of real estate was different in cause and effect variables depending on regional characteristics. Second, in terms of correlation between prices by type of real estate, positive (+) and negative (-) relationships were shown depending on regional characteristics. Third, it was found that the mutual influence of apartments, officetels, and collective commercial stores in the short term was not significant in terms of the impact relationship between prices by type of real estate. The empirical analysis results confirmed that there are differences in causality and correlation between prices by type of real estate depending on the market situation and characteristics of each region, and meaningful research results were derived that confirmed that the impact of price changes by type of real estate may vary depending on the movement of investment demand.
Why are Africa's Female Entrepreneurs Not Playing the Export Game? Evidence from Ghana

We explore the export performance of Africa's underperforming female entrepreneurs, using the Ghanaian ISSER-IGC panel, a comprehensive dataset of manufacturing firms for 2011–2015. Uniquely, the data provides information about the severity of key business constraints, across both male and female entrepreneurs. We find that females are less likely to export (and optimize their exporting) than their male peers. Although reduced access to finance seriously constrains the exports of female entrepreneurs, this limitation does not explain their relative inability to leverage value from exports. Consistent with related work, we find that certain social and cultural constraints, in particular constraints linked to bribes and security concerns, are more deeply felt by female entrepreneurs. This may hint at the exclusion of Africa's females (voluntarily or involuntarily) from male-dominated networks or business practices.
Targeting the hidden chromitite using geochemical vectoring for Bophivum area, northwestern Myanmar

&amp;lt;p&amp;gt;Harzburgite are the rocks that make up the mantle and consist of olivine, orthopyroxene, and clinopyroxene (&amp;lt;5 %). Clinopyroxene contain Ca, Al, and Ti, while orthopyroxene contain Al. On the other hand, olivine contains almost zero contents of Ca, Al and Ti. When the rising melt from the lower mantle passes through the mantle harzburgite, the clinopyroxene and orthopyroxene with lower melting points compared with olivine are fused into the melt, and the olivine is crystallized from the melt. In this genetic process, harzburgite gradually change into dunite consisting of only olivine, and Ca, Al and Ti of pyroxene in harzburgite will escape into the melt. And, as the melting point of clinopyroxene is lower than that of orhopyroxene, the Ca, Al, and Ti in clinopyroxene are escaped into the melt earlier than those in orthopyroxene. The melt with changed composition formed by melting the pyroxene are mixed with the newly rising melt with pyroxene, so that the chromian spinel in the melt becomes saturated and the chromitite are formed. By the above-mentioned mechanism, chromitite occurs with dunite and pyroxene-deficient harzburgite formed by the reaction result between melt and harzburgite. In other words, in the genetic process of high Cr chromitite, the presence of melt that fused the pyroxene within harzburgite is essential. And, in order to make high Cr chromitite, the melt must have been fused more pyroxene in harzburgite. As a result, the Ti, Ca, and Al content of harzburgite will be decreased. Therefore, considering the representative chemical composition of podiform chromitite(Robinson et al., 1997), we assumed that as we approached into harzburgite bearing high Cr chromitite(probably hidden ore body), the Ti, Ca and Al content within harzburgite will be likely to converge toward the specific contents(Ti&amp;lt;180ppm, Ca&amp;lt;0.9%, Al&amp;lt;0.7%). In case of Bophivum chromitite in northwestern Myanmar, it corresponds well with the representative chemical composition of high Cr chromitite in terms of the above-mentioned data. Therefore, we monitored to see whether Ti, Ca, and Al contents systematically change by the distance from the center with chromitite outcrop or high Cr anomaly zone confirmed through soil and rock geochemical exploration toward the surrounding harzburgite outcrop or not and tried to select the target element for geochemical vectoring using portable XRF. Conclusively, Ca is considered to be a more meaningful geochemical vectoring indicator than Al in terms of portable XRF measurements in the survey area.&amp;lt;/p&amp;gt;
Volcano-tectonic earthquake statistics for Campi Flegrei monitoring

&amp;lt;p&amp;gt;&amp;lt;span&amp;gt;The knowledge of the dynamic of the Campi Flegrei calderic system is &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;essential&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt; to mitigate the volcanic risk in one of the most densely populated volcanic areas in the world. From 1950 to 1985 three bradyseismic crises &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;occurred&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt; with a total uplift of &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;almost 3 m (Del Gaudio et al., 2010). After more than 20 years of subsidence, at the end of 2005 the uplift started again accompanied by a low increment in the seismicity rate. In 2012 a further increment in the seismicity rate was observed and a variation in the gas composition of the fumaroles of Solfatara (central area of the caldera) revealed the injection of magmatic fluids into the hydrothermal system (Chiodini et al., 2017). This suggests that the investigation of the seismicity can represent a very useful tool for the risk mitigation. Here we analyze the seismic catalogue of Campi Flegrei (collected by INGV - Osservatorio Vesuviano) to check for any variation of the observed seismicity. This can be eventually associated with geochemical monitored parameters. &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;In addition, we analyzed the most energetic swarms recorded in this period by comparing their locations, waveforms and source mechanisms.&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt; We find that occurrence rate, location and b-value change in time. The seismicity occurs in swarms, which&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;, in the last years, tends to became closer but with a smaller number of events.&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt; The &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;observed &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;variations are correlated also with &amp;lt;/span&amp;gt;&amp;lt;span&amp;gt;the&amp;lt;/span&amp;gt;&amp;lt;span&amp;gt; geochemical monitoring parameters suggesting that the uplift process has probably modified the elastic and permeability properties of the shallow part of the crust.&amp;amp;#160;&amp;lt;/span&amp;gt;&amp;lt;/p&amp;gt;

Firmansyah MA, Bhermana A. 2020. Characterization of earthworms (Lumbriscus terestris) population under several area of shallots cultivation. Jurnal Lahan Suboptimal : Journal of Suboptimal Lands 9(2): 208-217.In General, the problem of shallot commodities development was still used common farming without considering land suitability and other specific soil condition including aspect cultivation. The objective of this study was to clasify several lands characteristics for shallots cultivation and to observe earthworm (Lumbriscus terrestris) population based on their land suitability classes. The methodology used was land evaluation approach and field observation. This study was performed during Â rainy season in 2018 at three locations with different soils, namely, peat soils/Histosol (IST), buried soil of Quartzipsamment above peat soils (ENT), and dry land of Dystropept (EPT). The population of earthworms is obtained by digging up an area of 1 m2 with depth of 20 cm at in four places of location of study. The calculation of earthworms is conducted by hand sorting. The results showed that the highest land suitability class at EPT S3tr, rt, nr, while for other locations are not suitable. The location of IST is classified into N3fb with several limiting such as flooding hazard during rainy season, while for ENT location, classified into Nrt, limiting factor is rough texture. High suitability class is not identical with high earthworm population density. Cultivation aspect that is able to increase soil pH become neutral condition and lower pesticide application affect earthworm populations. ENT locations that have neutral soil pH with lower pesticides applcation have the highest earthworm populations. Earthworm population density from high to low involve ENT&gt; IST&gt; EPT or 74&gt; 33&gt; 31 tails/m2.

Comparing common still image quality metrics in recent High Dynamic Range (HDR) and Wide Color Gamut (WCG) representations

There are an increasing number of databases describing subjective quality responses for HDR (high dynamic range) imagery with various distortions. The dominant distortions across the databases are those that arise from video compression, which are primarily perceived as achromatic, but there are some chromatic distortions due to 422 and other chromatic sub-sampling. Tone mapping from the source HDR levels to various levels of reduced capability SDR (standard dynamic range) are also included in these databases. While most of these distortions are achromatic, tone-mapping can cause changes in saturation and hue angle when saturated colors are in the upper hull of the of the color space. In addition, there is one database that specifically looked at color distortions in an HDR-WCG (wide color gamut) space. From these databases we can test the improvements to well-known quality metrics if they are applied in the newly developed color perceptual spaces (i.e., representations) specifically designed for HDR and WCG. We present results from testing these subjective quality databases to computed quality using the new color spaces of J z a z b z and IC T C P , as well as the commonly used SDR color space of CIELAB.
Enhancing Information Hiding Capacity in Image Interpolation Based Steganography Scheme

Ma, Z.; Ma, Y.; Huang, X.H.; Zhang, M.J.; Liu, Y.X., and Su, B., 2020. Enhancing information hiding capacity in image interpolation based steganography scheme. In: Guido Aldana, P.A. and Kantamaneni, K. (eds.), Advances in Water Resources, Coastal Management, and Marine Science Technology. Journal of Coastal Research, Special Issue No. 104, pp. 245–250. Coconut Creek (Florida), ISSN 0749-0208.Information hiding using image interpolation was first introduced by Jung and Yoo in 2009, where one original image is expanded to by neighbor mean interpolation, and this expanded image is called cover image. The secret information can be then hided into those inserted pixels in this cover image, where the image with embedded secret information is called stego image. Recently Yang et al. adopt OPAP and LSB substitution in image interpolation, and construct a new data hiding scheme. This new data hiding scheme can improve stego image's quality of Jung-Yoo's work. However, the approaches of LSB and OPAP substitution are vulnerable with RS detection, which causes a serious secure problem. In this work, we construct a new image interpolation based information hiding scheme by using GEMD and RGEMD information hiding methods. The combination of GEMD (RGEMD) and image interpolation could not only resist RS detection, but also improve stego images' quality from Yang et al.'s scheme.
