OBJECTIVES:
Severe alcoholic hepatitis (sAH) confers substantial mortality, but the disease course is difficult to predict. As iron parameters are attractive outcome predictors in other liver diseases, we tested their prognostic ability in sAH.

METHODS:
Serum ferritin, transferrin, iron, transferrin saturation, nontransferrin-bound iron, soluble transferrin receptor, and hepcidin were measured in 828 patients with sAH recruited prospectively through the STOPAH trial. The cohort was randomly divided into exploratory (n = 200) and validation sets (n = 628).

RESULTS:
Patients with sAH had diminished serum transferrin but increased transferrin saturation. Among iron parameters, baseline transferrin was the best predictor of 28-day (area under the receiver operated characteristic 0.72 [95% confidence interval 0.67–0.78]) and 90-day survival (area under the receiver operated characteristic 0.65 [0.61–0.70]). Transferrin's predictive ability was comparable with the composite scores, namely model of end-stage liver disease, Glasgow alcoholic hepatitis score, and discriminant function, and was independently associated with survival in multivariable analysis. These results were confirmed in a validation cohort. Transferrin did not correlate with markers of liver synthesis nor with non–transferrin-bound iron or soluble transferrin receptor (as markers of excess unbound iron and functional iron deficiency, respectively).

DISCUSSION:
In patients with sAH, serum transferrin predicts mortality with a performance comparable with commonly used composite scoring systems. Hence, this routinely available parameter might be a useful marker alone or as a component of prognostic models.

AbstractThis research investigates the role of cash waqf as a Islamic social fund in eradicating poverty in Special Region of Yogyakarta. Researchers combine both of quantitative and qualitative research methods (triangulation) to increase the perceived quality of research findings. To answer the problems, researchers employe three steps analysis, firstly forecasting with statistical approach using the weighted moving average method; secondly cash waqf simulation; and thirdly researchers propose The New Integrated Model Of Cash Waqf Information System. The results of this study has succesfully answered the progress of cash waqf, the support of stakeholders (government, financial institutions and society) to achieve target of cash waqf. Based on the forecasting moving average method, it can be seen that the collected fund of cash waqf is still very fluctuating in some future period following the trend of cash waqf fund before. In the simulation of cash waqf based on expenditure distribution at DIY , to reach the target of cash waqf in one year, for example in 2018, that is equal to Rp. 684,646,315.33, each household only spend about of Rp. 60,000 to Rp. 80,000 per year. If all Muslim societies especially at DIY have realized the importance of cash waqf, then the potential cash waqf cant be maximized and the flow of cash waqf returns can be distributed to strengthen the social pillars of the region such as poverty, hunger, health and eduaction.

Published: January 2020

Abstract
This work presents an investigation into the ability of recurrent neural networks (RNNs) to provide long term predictions of time series data generated by coal fired power plants. While there are numerous studies which have used artificial neural networks (ANNs) to predict coal plant parameters, to the authors’ knowledge these have almost entirely been restricted to predicting values at the next time step, and not farther into the future. Using a novel neuro-evolution strategy called Evolutionary eXploration of Augmenting Memory Models (EXAMM), we evolved RNNs with advanced memory cells to predict per-minute plant parameters and per-hour boiler parameters up to 8 hours into the future. These data sets were challenging prediction tasks as they involve spiking behavior in the parameters being predicted. While the evolved RNNs were able to successfully predict the spikes in the hourly data they did not perform very well in accurately predicting their severity. The per-minute data proved even more challenging as medium range predictions miscalculated the beginning and ending of spikes, and longer range predictions reverted to long term trends and ignored the spikes entirely. We hope this initial study will motivate further study into this highly challenging prediction problem. The use of fuel properties data generated by a new Coal Tracker Optimization (CTO) program was also investigated and this work shows that their use improved predictive ability of the evolved RNNs.
Multi-scale modeling of the lamellar unit of arterial media

Published: January 2020

AbstractThe heterogeneity of the lamellar unit (LU) of arterial media plays an important role in the biomechanics of artery. Current two-component (fibrous component and a homogenous matrix) constitutive model is inappropriate for capturing the micro-structural variations in the LU, such as contraction/relaxation of vascular smooth muscle cells (VSMCs), fragmentation of the elastin layer, and deposition/disruption of the collagen network. In this work, we developed a representative volume element (RVE) model with detailed micro-configurations, i.e., VSMCs at various phenotypes, collagen fibers, and elastin laminate embedded in the ground substance. The fiber architecture was generated based on its volume fraction and orientations. Our multi-scale model demonstrated the relation between the arterial expansion and the micro-structural variation of the lamellar unit. The obtained uniaxial response of the LU was validated against the published experimental data. The load sharing capacity of fibrous component and VSMCs of the LU were obtained. We found that the VSMC could take 30% of the circumferential load when contracted until the collagen fibers were recruited, while this value was less than 2% for the relaxed VSMC. In addition, the contribution of collagen fibers at low stretch levels was negligible but became predominant when straightened in high stretches.Moreover, aging effects by collagen deposition was modeled to estimate the arterial stiffening. It was revealed that the aortic stiffness is mainly controlled by collagen fibers, instead of VSMCs. Our findings could shed some light about the contribution of VSMCs in arterial stiffness which has been under debate in recent years.

AbstractThe nanoscratch test has been identified as one of the important tools for evaluating the mechanical and tribological properties of materials. This paper reviews the current researches on the nanoscratch test using to characterise the mechanical properties of three typical materials, including thin film, polymer composite and concrete, from the perspectives of the Berkovich indenter, parameter selection, mode selection, and analysis of resulting data. In addition, to provide a deep understanding on the test from different magnitude, a comparison between the microscratch test and nanoscratch test on the evaluation of tribological performance is also provided in this paper. The characterisation by nanoscratch test of two structural samples, in terms of layered film structures (thin film and coating sample) and single layer block structure (polymer composite sample and concrete samples) are also described in this paper, which aims to provides a deep understand on the evaluation the adhesion, tribological and interfacial properties of the typical materials samples by nanoscratch test. Finally, the coefficient of friction and critical load are discussed, which are two important parameters in tribological properties and adhesion properties.
Hydrodynamic review on liquid–solid magnetized fluidized bed
Authors: Zhu Quanhong , Huang Qingshan , Yang Chao 
Published: January 2020

Abstract
The magnetic field has been successfully used to intensify the liquid–solid contact performance in the fluidized bed, creating the magnetized fluidized bed (MFB). The MFBs with purely magnetizable particles and with the binary admixture of magnetizable and nonmagnetizable particles could be simply termed the pure MFB and admixture MFB, respectively. Their potential application in the chemical and biochemical industries has been thoroughly explored in the literature. However, a fundamental investigation on the hydrodynamics therein is far from sufficient, severely hindering the commercial application. For this reason, this review summarized the relevant findings, including (1) flow regime transition, (2) boundaries between two adjacent flow regimes, (3) unique features of the magnetically stabilized bed, (4) hysteresis phenomenon and bed voidage, (5) minimum fluidization velocity and terminal velocity, (6) numerical simulation and segregation of the admixture MFB, and (7) some explored applications. More importantly, the existing controversies and unsolved issues in this area were identified. Among others, the flow regime transition and unique hydrodynamic characteristics of each flow regime should be first clarified, only after which could the terminology describing all the flow regimes be unified and the results from different scholars be compared.
Preservation of Partially Mixed Selectivity in Human Posterior Parietal Cortex across Changes in Task Context

Published: January 2020

AbstractRecent studies in posterior parietal cortex (PPC) have found multiple effectors and cognitive strategies represented within a shared neural substrate in a structure termed “partially mixed selectivity” (Zhang et al., 2017). In this study, we examine whether the structure of these representations is preserved across changes in task context and is thus a robust and generalizable property of the neural population. Specifically, we test whether the structure is conserved from an open-loop motor imagery task (training) to a closed-loop cortical control task (online), a change that has led to substantial changes in neural behavior in prior studies in motor cortex. Recording from a 4 × 4 mm electrode array implanted in PPC of a human tetraplegic patient participating in a brain–machine interface (BMI) clinical trial, we studied the representations of imagined/attempted movements of the left/right hand and compare their individual BMI control performance using a one-dimensional cursor control task. We found that the structure of the representations is largely maintained between training and online control. Our results demonstrate for the first time that the structure observed in the context of an open-loop motor imagery task is maintained and accessible in the context of closed-loop BMI control. These results indicate that it is possible to decode the mixed variables found from a small patch of cortex in PPC and use them individually for BMI control. Furthermore, they show that the structure of the mixed representations is maintained and robust across changes in task context.
VILLAGE AND CITY, OR HOW CULTURAL BOUNDARIES ARE CONSTRUCTED
Authors: Polek Tina 
Published: January 2020

The article deals with the spectrum of ideas about the boundary between rural and urban cultures and outlines the mechanism of this boundary constructing. Using social constructionism theory and discourse analysis was useful for exacerbating the dichotomous interpretation of rural and urban cultures.
The terminological definitions of the city and the village appear to be well established and self-evident, but attention to these basic definitions is very important for further analyses. Despite a thorough academic critique of the dichotomous understanding of the city and the village, these terms continue to refer to generalized idealized types of settlements that are inherently opposite. This means that they continue to be objects of social, academic and administrative construction, based primarily on population.
The classic definition of a city by L. Wirth includes population size, density and heterogeneity. However, the presence of targeted associations and economic institutions able to respond to diverse social needs are also an important feature of the city. At the same time, the village is considered as an opposition to a city with less population, as well as less density and heterogeneity. The traditional approach links rural areas to agricultural activity, but in modern conditions, this characteristic cannot be decisive since during the twentieth century the human population has become predominantly urban and this has violated established standards. A more important feature of a village is that living in a rural area implies a specific engagement with the local community, which is determined by active involvement in social networks.
Urban and rural cultures find expression in an appropriate way of life. Urbanism assumes the importance of anonymous daily contacts that are part of the urban discourse reflected in the categories of diversity, opportunity and temptation. Whereas rural discourse focuses on the value of traditions, among which the customs of neighbourhood mutual assistance are the most important.

Graphics Processing Unit-Based Match and Locate (GPU-M&L): An Improved Match and Locate Method and Its Application
Authors: Liu Min , Li Hongyi , Zhang Miao , Wang Tongli 
Published: January 2020

AbstractMicroearthquake detection and location are critical for understanding earthquake mechanisms and mitigating seismic hazards. Match and locate (M&L) is an effective method for simultaneously detecting and locating small earthquakes. However, the heavy computational demands of the M&L make it challenging to apply to big data. In this article, we develop an improved M&L method—called graphics processing unit-based M&L (GPU-M&L). The GPU-M&L differs from the M&L in two ways: (1) adding weighting factor for each component of templates to improve the detection ability and (2) implementing the M&L method on GPU to accelerate the computation. Synthetic tests show the GPU-M&L can not only handle smaller earthquakes than the M&L but also perform 4.5 times faster than the M&L parallelly programed on central processing unit. As an example, we utilize the GPU-M&L to study the seismic activity during seven days after the 2015 Ms 5.8 Alxa, China, earthquake (from 15 to 21 April 2015). Using 38 cataloged earthquakes as templates, we detect ∼20 times more events than in the routine catalog. The distribution of those detected events, along with focal mechanisms of large events, suggests that the 2015 Ms 5.8 earthquake occurred on an east–west-trending hidden strike-slip fault.
