A shape-variable aqueous secondary battery operating at low temperature is developed using Ga68In22Sn10 (wt%) as a liquid metal anode and conductive polymer (polyaniline (PANI)) cathode. In the GaInSn alloy anode, Ga active component, while Sn increase acid resistance decrease eutectic point to -19 °C. This enables use of strongly acidic electrolytes (here, pH 0.9), thereby improving activity s...

The major obstacle to extensive use of cokriging for integration of multiple data types in estimation is the requirement of modeling a positive definite covariance matrix of size K by K including up toK different terms if K coregionalized variables are considered. In practice, this matrix is modeled using a linear model of coregionalization (LMC); each covariance is modeled by a different linea...

In this paper, we report some findings of a study on attitude and mathematics achievement at the senior secondary school level in Botswana. We adopted a new methodology in the analysis of the relationship between attitude, gender bias and achievement in mathematics with gender as a dummy variable. The method, quantile regression (QReg), was used because it unveils the relationship at the quanti...

There are several candidate measures when asking which psychological construct significantly predicts academic performance. Hundreds of studies have addressed this issue by measuring intelligence, basic cognitive processes, or personality. However, the simultaneous consideration of a broad and varied array of measures is much less common. Here we consider several cognitive and personality measu...

Real-time detection of lead-acid battery capacity is hard for not having the suitable instrument. The soft sensing method is considered. It is studied on the basis of variable selection, the confirming of structure and parameters for the predicted model. The importance of each related nonlinear secondary variable is computed and sorted with RReliefF method. After that, the secondary variable se...

Loops are structurally variable regions, but the secondary structural elements bracing loops are often conserved. Motifs with similar secondary structures exist in the same and different protein families. In this study, we made an all-PDB-based analysis and produced 495 motif families accessible from the Internet. Every motif family contains some variable loops spanning a common framework (a pa...

This paper simplifies the energy recovery process in the series hydraulic hybrid bus’ energy regeneration system into a process in which the main axle’s moment of inertia drives the secondary element variable delivery pump/motor and brings hydraulic oil from the oil tank to the accumulator. This process enables braking of the vehicle and also allows recovery of energy to the accumulator. Based ...

We present the K-band spectrum of the cataclysmic variable RXJ 0502.8+1624 (Tau 4). The spectrum shows a broad, smooth hump, with no absorption lines from the secondary star visible. This result indicates that the infrared light of this system is dominated by cyclotron emission, and, in combination with the optical spectrum and X-ray properties, suggests that Tau 4 is a polar-type cataclysmic v...
