A flexible class of dependence-aware multi-label loss functions

The idea to exploit label dependencies for better prediction is at the core of methods for multi-label classification (MLC), and performance improvements are normally explained in this way. Surprisingly, however, there is no established methodology that allows to analyze the dependence-awareness of MLC algorithms. With that goal in mind, we introduce a class of loss functions that are able to capture the important aspect of label dependence. To this end, we leverage the mathematical framework of non-additive measures and integrals. Roughly speaking, a non-additive measure allows for modeling the importance of correct predictions of label subsets (instead of single labels), and thereby their impact on the overall evaluation, in a flexible way. The well-known Hamming and subset 0/1 losses are rather extreme special cases of this function class, which give full importance to single label sets or the entire label set, respectively. We present concrete instantiations of this class, which appear to be especially appealing from a modeling perspective. The assessment of multi-label classifiers in terms of these losses is illustrated in an empirical study, clearly showing their aptness at capturing label dependencies. Finally, while not being the main goal of this study, we also show some preliminary results on the minimization of this parametrized family of losses.

A systematic ethnobotanical review of Adhatoda vasica (L.), Nees.

Adhatoda vasica (L.), Nees belonging to the family Acanthaceae is a shrub with opposite ascending branches. The plant has been used in the indigenous system of medicine in India for near about 2500 years. It is a well-known plant as a drug in Ayurvedic and Unani medicines. Traditionally it was used for the treatment of various acute and chronic diseases and showed strong pharmacological activity particularly for bronchial infections, cough, bacterial infections, reproductive disorders, cardiac diseases and many more. Various phytochemicals like alkaloids, flavonoids, tannins, etc. were obtained from Adhatoda vasica (A. vasica). The active constituent of the plant is vasicine, l-vasicinone, deoxyvasicine, maiontone, vasicinolone and vasicinol etc. This review consists of updated information on the phyto-constituents isolated from A. vasica and their potential role in the treatment of various ailments traditionally and medically. Based on the critical review it was concluded that there is not sufficient scientifically strong evidence to explain that A. vasica extract, could be harmful to human beings especially in pregnant women. Major data on traditional uses as well as toxicological studies, evaluated various correctness, relevance, importance, and reliability for the overall evaluation of A. vasica safety. Numerous clinical trials are conducted around the globe on the herbal formulations of vasaka. This review includes strong data about phytochemical and ethnopharmacological studies that indicate that A. vasica is a versatile native plant of the Indian subcontinent having a commercial reputation and thus can be encouraged for diversified applications like medicinal and other potential uses.

Dimensional stability and decay resistance of clay treated, furfurylated, and clay-reinforced furfurylated poplar wood

Plantation-grown poplar (Populus cathayana) is regarded as a source of low-quality wood, with poor dimensional stability and low decay resistance. In this study, poplar wood was impregnated with sodium montmorillonite (Na-MMT) or organo-montmorillonite (O-MMT), furfuryl alcohol (FA, at concentrations of 15%, 30% and 50%), separately or in their combinations to prepare clay treated, furfurylated, and clay-reinforced furfurylated wood, respectively. The two-step method by introducing Na-MMT first and then FA and organic modifier was feasible to achieve a reasonable penetration. These components could entirely enter the wood cell lumen or partly enter the wood cell wall, and thus initiate a series of reactions. Compared with Na-MMT reinforced furfurylated wood (M-F), the O-MMT reinforced furfurylated wood (O-F) exhibited better dimensional stability (ASE up to 71%) and decay resistance (3.2% mass loss). Moreover, O-MMT played a predominant role in decay resistance of O-MMT reinforced furfurylated wood. Even at low O-MMT loadings, the modified wood had a significant inhibitory effect on the white-rot decay fungus Trametes versicolor. Based on an overall evaluation, O-MMT reinforced furfurylated wood seemed to provide an optimal choice for both moist or wet conditions.

Development of Tele-Operated Underfloor Mobile Manipulator

In this study, we propose a tele-operated mobile manipulator for conducting underfloor work, including both inspection and repair. We focus on a caulking operation, and develop a mobile manipulator for finding and repairing cracks in a foundation. When designing the mobile manipulator, we consider a typical narrow underfloor environment, and perform detailed calculations. As a user interface, we furnish an image-pointing system for enabling us to operate the manipulator simply by clicking on a hand camera image. Then, we evaluate its performance based on navigation experiments, trajectory tracking experiments, and overall evaluation experiments.

Heat Transfer Enhancement of Impingement Cooling by Different Crossflow Diverters

Impingement cooling can effectively disperse local heat load, but its downstream heat transfer is always reduced due to crossflow effect. In this study, the flow and heat transfer characteristics of impingement cooling with Semi-Circular (SC), Semi-Rectangular (SR), Semi-Diamond (SD) and Semi-Four-pointed Star (SFS) crossflow diverters are compared over the ReD ranging from 3,500 to 14,000 by solving three dimensional Reynolds-Averaged Navier-Stokes (RANS) equations with SST k-? turbulence model. It is found that crossflow diverters change the distribution of local jet Reynolds number (ReD,j/ReD) and reduce the mass velocity ratio of downstream crossflow to jet (Gcf/Gj), so they enhance the heat transfer significantly, but also come at the cost of friction loss. Overall evaluation reveals that various crossflow diverters can improve the comprehensive heat transfer performance parameter (F), and the maximum increases are 11.0%, 14.3%, 12.2% and 14.7% for SC, SR, SD and SFS cases respectively. It is noted that the Nusselt number of heated SFS-shaped diverter surface is also the highest. Besides, the influences of streamwise location (L) and thickness (t) of SFS-shaped diverter are also investigated. Results show that the heat transfer and friction loss change a little when the L increases from 2D to 3D, but the heat transfer decreases sharply and friction loss increases seriously when the L increases from 3D to 4D. With respect to the t, it has almost no effect on the flow field and heat transfer.

Genetic Variability, Population Structure, and Relatedness Analysis of Meagre Stocks as an Informative Basis for New Breeding Schemes

This study evaluates the genetic diversity of different meagre broodstocks sampled in Greece. A multiplex of twelve microsatellite markers was used to genotype 946 fish from eleven stocks and batches used for broodstock selection, and the genetic data was used to calculate genetic population parameters as well as to investigate the genetic differentiation between stocks. The results from a relatedness analysis were used as the guiding lines for a fine-tuned and overall evaluation of the genetic distance between stocks, and the choice of candidate breeders from some of them. The approach implemented in this study uses well-established population genetics methods to evaluate the selection of breeder candidates in aquaculture commercial conditions utilizing a descriptive genetic data set based on microsatellite analyses, and to outline an efficient methodology for establishing the basis of new breeding schemes.

Research on Design of Stalk Furniture Based on the Concept and Application of Miryoku Engineering Theory

Through discussion on the disposal of crop stalks in rural China, where stalks are usually burned in the open air, resulting in the production of a large amount of smoke and air pollution, this study has been conducted to discuss the reasonable and effective use of waste stalks, and to explain the excellent characteristics of stalks from the perspective of green, ecological sustainable design and user perceptual needs, as well as the application of stalks in furniture design. In view of the accuracy of stalks in the design of furniture products, the paper has adopted the evaluation grid method in Miryoku engineering to guide the design practice. In the research process, interviews were first conducted on the basis of sample selection, then based on the expert opinion survey method, eight testers were selected for in-depth interviews. Key words of charm factors were extracted from 190 picture samples, and then a personal evaluation structure map and statistical data were built to construct an overall evaluation structure of the rural style stalk furniture. Next, the score value of the charm factor of stalk furniture was analyzed through the Likert scale questionnaire, the charm factor and specific performance characteristics of the rural style were sorted, followed by a proposed design method. Finally, the effectiveness of the design strategy was verified with the design of stalk furniture in rural style. The study emerged with the feasibility of the design of furniture products made of stalks. The results of the study have shown the correlation between the elements of furniture products and the perceptual image of users. Furthermore, the results have demonstrated the reuse value of waste stalks and improved the innovative design of stalks in the home furnishing field, which conveys the concept of sustainable development.
