Cell interaction with biomaterials is one of the keystones to developing medical devices for tissue engineering applications. Biomaterials are the scaffolds that give three-dimensional support to the cells, and are vectors that deliver the cells to the injured tissue requiring repair. Features of biomaterials can influence the behaviour of the cells and consequently the efficacy of the tissue-engineered product. The adhesion, distribution and motility of the seeded cells onto the scaffold represent key aspects, and must be evaluated in vitro during the product development, especially when the efficacy of a specific tissue-engineered product depends on viable and functional cell loading...

Shuang-Bo Sun, Zhi-Heng Zhang, Xin-Ling Dong, Heng-Ru Zhang, Tong-Jun Li, Lin Zhang, Fan Min
This paper proposes a new measure for recommendation through integrating Triangle and Jaccard similarities. The Triangle similarity considers both the length and the angle of rating vectors between them, while the Jaccard similarity considers non co-rating users. We compare the new similarity measure with eight state-of-the-art ones on four popular datasets under the leave-one-out scenario. Results show that the new measure outperforms all the counterparts in terms of the mean absolute error and the root mean square error...

BACKGROUND: Identification of the source of mosquito blood meals is an important component for disease control and surveillance. Recently, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) profiling has emerged as an effective tool for mosquito blood meal identification, using the abdomens of freshly engorged mosquitoes. In the field, mosquito abdomens are crushed on Whatman filter papers to determine the host feeding patterns by identifying the origin of their blood meals...

Network modeling in electromagnetics is an effective technique in treating scattering problems by canonical and complex structures. Geometries constituted of angular regions (wedges) together with planar layers can now be approached with the Generalized Wiener-Hopf Technique supported by network representation in spectral domain. Even if the network representations in spectral planes are of great importance by themselves, the aim of this paper is to present a theoretical base and a general procedure for the formulation of complex scattering problems using network representation for the Generalized Wiener Hopf Technique starting basically from the wave equation...

Metallic Na anode is considered as the promising alternative candidate for Na ion batteries (NIBs) and Na metal batteries (NMBs) due to the high specific capacity, low potential. However, the unstable solid electrolyte interphase (SEI) layer caused by serious corrosion and reaction in electrolyte will lead to big challenges, including dendrite growth, low Coulombic efficiency and even safety issues. In this paper, we firstly demonstrate the inorganic-organic coating via advanced molecular layer deposition (alucone) as protective layer for metallic Na anode...

Fulminant type 1 diabetes (fT1D) is a new subtype of type 1 diabetes proposed by Imagawa in 2000. It is a clinical syndrome characterized by a markedly rapid and almost complete destruction of pancreatic β cells. Metabolic derangement is more severe in this subtype than in autoimmune type 1 diabetes. The incidence of fT1D is associated with HLA DRB1*04:05DQB1*04:01, both innate and acquired immune disorders might contribute to the development of fT1D. The presence of specific innate immune responses to enterovirus infection connected with enhanced adoptive immune pathways responsible for aggressive β cell toxicity in fT1D...

Zhangtao Li, Jing Liu, Kai Wu
Most of the existing community detection algorithms are based on vertex connectivity. While in many real networks, each vertex usually has one or more attributes describing its properties which are often homogeneous in a cluster. Such networks can be modeled as attributed graphs, whose attributes sometimes are equally important to topological structure in graph clustering. One important challenge is to detect communities considering both topological structure and vertex properties simultaneously. To this propose, a multiobjective evolutionary algorithm based on structural and attribute similarities (MOEA-SA) is first proposed to solve the attributed graph clustering problems in this paper...

Obstructive sleep apnea (OSA) is a chronic sleep disorder affecting millions of people worldwide. Individuals with OSA are rarely aware of the condition and are often left untreated, which can lead to some serious health problems. Nowadays, several low-cost wearable health sensors are available that can be used to conveniently and noninvasively collect a wide range of physiological signals. In this paper, we propose a new framework for OSA detection in which we combine the wearable sensor measurement signals with the mathematical models of the cardiorespiratory system...

Artificial neural networks (ANNs) aim to simulate the biological neural activities. Interestingly, many ''engineering'' prospects in ANN have relied on motivations from cognition and psychology studies. So far, two important learning theories that have been subject of active research are the prototype and adaptive learning theories. The learning rules employed for ANNs can be related to adaptive learning theory, where several examples of the different classes in a task are supplied to the network for adjusting internal parameters...

How to solve the classification problem with only label proportions has recently drawn increasing attention in the machine learning field. In this paper, we propose an ensemble learning strategy to deal with the learning problem with label proportions (LLP). In detail, we first give a loss function based on different weights for LLP, and then construct the corresponding weak classifier, at the same time, estimate its conditional probabilities by a standard logistic function. At last, by introducing the maximum likelihood estimation, we propose a new anyboost learning system for LLP (called Adaboost-LLP)...

Hyperspectral images (HSIs) possess non-negative properties for both hyperspectral signatures and abundance coefficients, which can be naturally modelled using cone-based representation. However, in hyperspectral target detection, conebased methods are barely studied. In this paper, we propose a new regularised cone-based representation approach to hyperspectral target detection, as well as its two working models by incorporating into the cone representation l2-norm and l1- norm regularisations, respectively...

As an extension of High Efficiency Video Coding (HEVC), the Scalable High Efficiency Video Coding (SHVC) introduces multiple layers with inter-layer predictions, which greatly increases the complexity on top of the already complicated HEVC encoder. In Intra prediction for Quality SHVC, Coding Tree Unit (CTU) allows recursive splitting into four depth levels, which considers 35 Intra prediction modes and interlayer reference (ILR) mode to determine the best possible mode at each depth level. This achieves the highest coding efficiency but incurs a substantially high computational complexity...

Piezoelectric vibration energy harvesters often consist of a cantilevered beam composed of a support layer and one or two piezoelectric layers with a tip mass. While this configuration is advantageous for maximizing electromechanical coupling, the mechanical properties of the piezoelectric material can place limitations on harvester size and resonant frequency. Here, we present numerical and experimental results from a new type of piezoelectric energy harvester in which the mechanical properties and the resonant frequency of the cantilever beam resonator are effectively decoupled from the piezoelectric component...

The inclusion of Gaming Disorder (GD) criteria in the 11th Revision of the International Classification of Diseases (ICD-11) beta draft was recently criticized, and an argument was made for its removal to "avoid a waste of public resources." However, these misleading statements are believed to be based on under estimation of this ever-growing problem. Such claims may endanger public health and the psychosocial well-being of affected individuals. Thus, the seriousness of the problem was briefly emphasized in our response paper...

Background The recent paper by Aarseth et al. (2016) questioned whether problematic gaming should be considered a new disorder particularly because "Gaming Disorder" (GD) has been identified as a disorder to be included in the next (11th) revision of the World Health Organization's International Classification of Diseases (ICD-11). Methods This study uses contemporary literature to argue why GD should be included in the ICD-11. Results Aarseth and colleagues acknowledge that there is much literature (including papers by some of the authors themselves) that some individuals experience serious problems with video gaming...

Semiconducting polymer dots (Pdots) have recently emerged as a novel type of ultrabright fluorescent probes that can be widely used in analytical sensing and material science. Here we developed a dual visual agents based on Pdots for anti-counterfeiting applications. We first designed and synthesized two types of photoswitchable Pdots by incorporating photochromic dyes with multi-color semiconducting polymers to modulate their emission intensities and wavelengths. The resulting full-color Pdot assays showed the colorimetric and fluorescent dual-readout abilities to serve as an anti-counterfeiting reagent with low background interference...

Calcific aortic valve disease (CAVD) is the most prevalent heart valve disorder. Gene variant in the LPA gene, which encodes for apolipoprotein(a), has been associated at the genome-wide level with CAVD. The process whereby Lp(a) promotes the development of CAVD is under intensive investigation and recent data have shed important insights into disease biology. In this regard, autotaxin (ATX), a lysophospholipase D, interacts with Lp(a) and promotes the mineralization of the aortic valve. Areas covered: In this paper, we are reviewing the biology of Lp(a) and the latest discoveries about the molecular processes that link this lipoprotein with the development of CAVD including the role of ATX...
