Herein, it is aimed to highlight the importance of process parameter choice during directional solidification polymer solutions, as they have a significant influence on pore structure and orientation. Biopolymer solutions (alginate chitosan) are directionally frozen, while systematically varying parameters such external temperature gradient, overall system, temperatures cooling surfaces. In add...

This paper presents an error analysis and correction model for four structured light methods applied to three common types of biological tissue; skin, fat and muscle. Despite its many advantages, structured light is based on the assumption of direct reflection at the object surface only. This assumption is violated by most biological material e.g. human skin, which exhibits subsurface light ref...

Oil palm ash (OPA), a bio-agricultural waste from oil palm mills, was subjected to high-energy ball milling for 30 h and was converted into a nano-structured material. The nano-structured OPA was characterized for its particle size and crystallinity index by using Transmission Electron Microscopy (TEM) and X-ray Diffraction (XRD) analysis. The crystallite size obtained from TEM and XRD was foun...

We present the design of a structured material supporting complete absorption of sound with a broadband response and functional for any direction of incident radiation. The structure which is fabricated out of porous lamellas is arranged into a low-density crystal and backed by a reflecting support. Experimental measurements show that strong all-angle sound absorption with almost zero reflectan...

In the supplementary material we want to provide reviewers with more visual examples of our method compared to SIFT-based Active Search [4] and CNN-based PoseNet [3] on outdoor sequences of Cambridge Landmarks [3]. To this end, we obtained dense reconstructions of the datasets using PMVS2 [2] and CMVS [1], which we then projected into the images using the poses computed by each method. Fig. 1 s...

We have shown that with our enhanced representation, the ranking problem for given weights w reduces to the one in Joachims (2005) in the case of a fully-factored model. Here we show a similar result for the learning problem. Recall that our learning objective is defined as: min w λ 2 w 2 + 1 M m max z∈Z w ϕ(x m , z) + ∆ AU C (z, y m) − maxˆz∈Zˆz∼y m w ϕ(x m , ˆ z) (1) We would like to consider...

In order to model the distribution of input variables, a reasonable assumption is that input variables x are generated by some process u, and that process has a Gaussian error. Thus, the distribution of input variables can be presented as ppxq N pu,Σxq. The new data point for prediction will be annotated as x . In the general case, we predict on the entire set of points representing a single sn...

Exploring the structural stability and elasticity of hexagonal ε-NbN helps discover correlations among its physical properties for scientific and technological applications. Here, for the first time, we measured the ultra-incompressibility and high shear rigidity of polycrystalline hexagonal ε-NbN using ultrasonic interferometry and in situ X-ray diffraction, complemented with first-principles ...

Porous- and hollow-structured LiNb3O8 anode material was prepared by a hydrothermal-assisted sintering strategy for the first time. The phase evolution was studied, and the formation mechanism of the porous and hollow structure was proposed. The formation of the unique structure can be attributed to the local existence of liquid phase because of the volatilization of Li element. As the anode ma...

The proof is based on the optimality conditions on β̂ for the original problem, and those on β̌ for the restricted problem. We first observe that β̌n exists, since the function x 7→ ‖x‖1 is coercive. Recall that β̌n is assumed to be uniquely defined. To achieve sparsistency, it suffices that β̂n = β̌n and supp β̌n = suppβ ∗. We derive sufficient conditions for β̂n = β̌n in Lemma 2.1, and make this suffi...
