Published: November 2019

This paper mainly takes Cangzhou City as an example to study spatial distribution of influence factors of residential land price, in order to deeply understand the driving factors of the spatial heterogeneity of residential land price in Cangzhou City. Based on the GWR model, the analysis of the influence factors of residential land price shows that the urban center has a significant positive impact on land prices, that is, the closer to the city center, the higher the land price is. The main roads, schools, and parks have different positive impacts on residential land prices, and there are large spatial differences in the degree of influence of various factors. The canal has a negative impact on residential land prices, that is, the closer to the canal, the lower the land price, mainly due to the existence of villages in city on both sides of the canal, which has a certain inhibitory effect on land prices. The impact of hospitals on residential land prices is not regular in spatial distribution.

Published: November 2019

During the plate rolling process, due to the influence of the asymmetry conditions, the head of the rolled piece often shows bending. When the head of the rolled piece is bent to a certain extent, the damage to the on-site production equipment is extremely great. It is important to study how to control the head bending phenomenon in the production process to the actual production process. This paper chooses the range of parameters in which the plate is prone to head bending, and establishes the thermo-mechanical coupling model of finite element. Based on the inlet thickness, reduction ratio and roller speed difference as the initial conditions, the head bending was simulated to analyse the law affecting the plate head bending. At the same time, artificial neural network is used to train the simulation result data, and the nonlinear mapping relationship between each influencing factor and the head bending value is obtained, and then the control method of the plate head bending is established. The research in this paper has practical guiding significance for the development of plate technology.

Published: November 2019

Inertial sensors carried by buoys, such as accelerometers, are widely used in wave characteristics measurement. Traditional methods usually employ numerical integration on the accelerate data for wave height, where the “drifting” errors are intractable. In this paper we propose a novel method to predict wave height and period using machine learning approach, specially a convolutional neural network. The end-to-end 1D convolutional neural network named WaveNet predicts wave height and period from the raw acceleration data directly. We designed a simple device to simulate the motion of the buoy in the wave, and used it to collect data for training and testing our model. The results of the proposed method were compared with traditional numerical integration method and found that the proposed model outperforms existing method in outputting more accurate wave height and period.

This research was conducted in two villages with poor category, Wonoroto and Ngemplak villages, Windusari subdistrict of Magelang regency, aiming to know the potential of local resources for the development of goats, in order to eradicate poverty. Primary data were taken by census of 35 goat farmers in the two villages, while competitor’s livestock data were sampled on 50 sheep breeder. Cattle competitors’ data were calculated based on monograph data of two research villages. The data analysis was done descriptively on the production of forage (in dry matter), goats population on adult, young and kid phase. Based on the results of the research, it was known that every household of goat farmers had production of feed sources (dry matter) for ruminant livestock as much as 1954.87 kg. Thus, the capacities of livestock per household were 0.85 animal unit equivalent to 6 adult goats or 1 head of heifers. It was found that the average land that produced fodder for two villages was 350.77 ha. The production of forage (DM) in Ngemplak and Wonoroto villages in one year averaged 363.05 ton/year or total of two villages was 726.10 ton/year, then the two areas had the capacity of livestock as much as 315.69 AU or about 157.85 AU for each village. The performance of goat reproductive in two areas, the average sex ratio was 1: 6.5, with the first kidding of 18 months, the kidding interval of 8.9 months and littersize 1.3. It is concluded that each goat-raiser family is still possible to increase its ownership, the area of two poor villages is still able to accommodate goats as much as 8,275 AU, with reproduction status which still needs to improve again.

The research was conducted in a cow pen belonging to the Anhini Lestari Livestock group in Karanganyar Regency. The purpose of this research are 1) to examine the effect of giving fermented rice straw in rations to the performance of beef cattle; 2) to assess how much fermented rice straw can replace the elephant grass. The design was used a completely andomized design in one way pattern as 3 types of treatments and each treatment was repeated for 4 times. This research used 12 heads of PO cattle, about 2 years old cow, which were treated with the formula ration as follows: T0: 60% concentrate + 40% elephant grass; T1: 60% concentrate + 20% elephant grass + 20% fermented rice straw; T2: 60% concentrate + 20% the elephant grass + 20% the rice straw without fractionation. Variables that is observed including the consumption of dry matter, consumption of crude protein and daily weight gain. The obtained data were analyzed using variance analysis with a level of 1% and 5%, if there were differences between treatments Duncan’s New Multiple Range Test was carried out. The results of this research showed that the utilization of fermented rice straw in the ration had a very significant effect on the performance of PO beef cattle. The best treatment in improving the performance of PO cattle was in T1 treatment, namely PBBH of 440 g/head/day; BK consumption is 21075 gr/head/day; PK consumption of 2264,529 gr/head/day. It can be concluded that fermented rice straw using a combination of Aspergillus niger and Trichoderma mutants AA1 can replace elephant grass by 20%.
Metal-insulator-metal plasmonic grating filter with suppressed Rayleigh anomaly

Published: November 2019

Plasmonic grating filters can be fabricated in single lithography process and reduce the cost of colour filters used in hyperspectral cameras. Due to the presence of Rayleigh Anomaly (RA) peak, however, it has not been possible to design filter array spanning wide-spectral-range without sacrificing spectral purity. In this paper, a plasmonic grating filter design using Metal-Insulator-Metal (MIM) with suppressed RA peak is presented. Proposed filter allows extending spectral range without sacrificing spectral purity. Using proposed MIM structure, surface plasmon polariton (SPP) mode supported on air side of bottom grating structure is cancelled by second set of SPP mode on top grating structure. This allows designing filter array with improved spectral range and achieves better than 2× improvement in suppression of the Rayleigh Anomaly peak.
Sound and Silence in Peter Jackson’s They Shall Not Grow Old
Authors: Meyer Jessica
Published: November 2019

This roundtable offers four diverse perspectives on Peter Jackson’s innovative and controversial World War I documentary film They Shall Not Grow Old (2018). Jackson’s film breaks the mold of the documentary genre in its manipulation and montage of the visual and audio archives held at the Imperial War Museum in London. Yet he puts his technical virtuosity and resources at the service of a very traditional interpretation of the war, focusing almost entirely on the experience of young Englishmen on the Western Front. Scholars Santanu Das, Susan R. Grayzel, Jessica Meyer, and Catherine Robson offer their reflections on both the gains and losses of Jackson’s paradoxical original use of historical documents and old-fashioned rendering of the war’s experiential elements. They consider, respectively, the experience of colonial troops, the place of women in the war, and Jackson’s creative, if controversial, interpretation of the visual and aural archive.
Development of health-system inpatient pharmacy clinical metrics
Authors: Cassat Stacy , Massey Lindsay , Buckingham Stephanie , Kemplay Tamara , Little Jeff
Published: November 2019

Purpose

To describe a process to identify metrics that represent the impact of inpatient pharmacy services on patient outcomes across a health system.

The authors describe a systematic process of identifying inpatient clinical outcome measures that could represent pharmacists’ impact on patient outcomes and eventually be displayed in a dashboard within the electronic medical record (EMR). A list was generated through literature review, assessment of practices at other sites, evaluation of current pharmacy services, and collaboration with the quality department and System Pharmacy Clinical User Group. The project team narrowed the list through assessment against standardized criteria. An assessment tool was designed and distributed to stakeholders to prioritize clinical outcome measures for inclusion on the dashboard. The clinical outcome measures were transformed into metrics by determining measurement criteria, inclusion and exclusion parameters, and review time frame. After validation, the metrics are planned to be displayed on an inpatient pharmacy EMR dashboard. Exemption from institutional review board review was granted for this project.

Conclusion

A systematic process was developed and used to identify inpatient clinical outcome metrics.
On higher-order logical grounds
Authors: Fritz Peter
Published: November 2019

Existential claims are widely held to be grounded in their true instances. However, this principle is shown to be problematic by arguments due to Kit Fine. Stephan Krämer has given an especially simple form of such an argument using propositional quantifiers. This note shows that even if a schematic principle of existential grounds for propositional quantifiers has to be restricted, this does not immediately apply to a corresponding non-schematic principle in higher-order logic.

Salinization leads to several worldwide damages in agricultural regions, mainly in semiarid regions where leaching of salt is poor due to limited and erratic rainfall. Cotton (Gossypium hirsutum L.) is a Malvaceae with wide genetic variability to salt stress. The identification of salinity tolerant genotypes is a dynamic target in a breeding program, and the selection is often based on plant phenotypes. Molecular markers are reliable tools to aid in these selection procedures. Aquaporin (AQPs) are channel proteins that play fundamental role in water relations and tolerance to environmental stresses. Plants have fine regulation of water transport through AQPs activities. In order to evaluate the AQP expressions of different cotton cultivars submitted to salt stress, we use molecular and physiological tools, based on RT-qPCR and gas exchange assays. Seven cultivars were submitted to 95 mM NaCl, started at V3 stage (21 days after emergence), during 72 h. At the end of stress treatment, root tissues were used to total RNA extraction, followed by cDNA synthesis and RT-qPCR analyzes. Three sets of specific primers were used, drawn from AQP accessions deposited in NCBI. Additionally, full expanded leaves were used to gas exchange assays and to estimate the relative water content. The dry matter of the shoots was also evaluated. Based on pattern of AQPs transcripts, we found that all semiarid tolerant cultivars (BRS Seridó, 7MH, CNPA MT 2009 152 and BRS 416) showed downregulation of AQP subtypes, mainly GhPIP1;1 and GhTIP2;1 whose action is characterized as tolerant to salinity. The results of gas exchanges, relative water content and dry matter were consistent with the molecular findings in these cultivars, confirming that GhPIP1;1 and GhTIP2;1, located at plasma membrane and vacuoles, respectively, could be adopted as AQP markers for identification of cotton tolerant to salt stress.

Drug–target interactions (DTIs) play a crucial role in target-based drug discovery and development. Computational prediction of DTIs can effectively complement experimental wet-lab techniques for the identification of DTIs, which are typically time- and resource-consuming. However, the performances of the current DTI prediction approaches suffer from a problem of low precision and high false-positive rate. In this study, we aim to develop a novel DTI prediction method for improving the prediction performance based on a cascade deep forest (CDF) model, named DTI-CDF, with multiple similarity-based features between drugs and the similarity-based features between target proteins extracted from the heterogeneous graph, which contains known DTIs. In the experiments, we built five replicates of 10-fold cross-validation under three different experimental settings of data sets, namely, corresponding DTI values of certain drugs (SD), targets (ST), or drug-target pairs (SP) in the training sets are missed but existed in the test sets. The experimental results demonstrate that our proposed approach DTI-CDF achieves a significantly higher performance than that of the traditional ensemble learning-based methods such as random forest and XGBoost, deep neural network, and the state-of-the-art methods such as DDR. Furthermore, there are 1352 newly predicted DTIs which are proved to be correct by KEGG and DrugBank databases.
