Abstract:
Biogranules are recently regarded as promising methods with intensive density and satisfying settleability for waste treatment and resource recovery. Wastewater treatment plants (WWTP) were regarded as “sinks” for Microplastics (MPs) and amount of MPs entrapped in the sludge. MPs have been reported to harm the granular characteristics and wastewater treatment efficiency. Previous research stated that the harmful effect on granular sludge is closely associated with the sizes and concentrations of MPs. However, there is still a lack of a comprehensive summary of granular characteristics variatio

Abstract:
The sense of touch is essential for locating buried objects when vision-based approaches are limited. We present an approach for tactile perception when sensorized robot fingertips are used to directly interact with granular media particles in teleoperated systems. We evaluate the effects of linear and nonlinear classifier model architectures and three tactile sensor modalities (vibration, internal fluid pressure, fingerpad deformation) on the accuracy of estimates of fingertip contact state. We propose an architecture called the Sparse-Fusion Recurrent Neural Network (SF-RNN) in which sparse

Abstract:
A model describing a given system should be as simple as possible – but not simpler. The appropriate level of complexity depends both on the type of system and on the intended use of the model. This paper addresses the critical question of which purposes justify increased complexity of biofilm (reactor) models. Additional model features compared to conventional models considered are: (1) the inclusion of microbial diversity, distinguishing between different species performing the same function; and (2) the distinction between flocs and granules in putatively granular sludge reactors.

Abstract. Manifestations of the so-called structure induced nonlinearity are considered for the case of a granular medium, the latter being a generally accepted model of nonconsolidated rocks in seismics. The consideration is carried out using the medium model in the form of the "ideal" random packing of spherical elastic granules in which the interparticle space can be filled with a fluid. A physical equation of such a medium is derived; the dependencies of nonlinear parameters on the grain material elastic moduli, the fluid compressibility and the initial medium strain are analyzed.

Background: In the diagnostic work-up of lupus erythematosus (LE), direct immunofluoresence (DIF) examination could be helpful. Classically, clinically red lesions are targeted by clinicians in the hope of yielding an informative DIF result. However, the investigative correlation between the degree of inflammation and DIF positivity has never been published in the literature. Objective: In this study, we sought to discover if histologically inflamed lesions correlated with DIF positivity results. Method: We studied 112 lesions histologically consistent with LE and correlated the degree of hist

Abstract Abstract 1606 Introduction: Large granular lymphocytic leukemia (LGL leukemia) is a rare lymphoproliferative disorder characterized by the presence of increased numbers of LGL cells in the peripheral blood. Discrimination of LGL leukemia and reactive T-cell processes is difficult and a matter of controversial discussion. Very recently, somatic STAT3 mutations located in the Src homology 2 domain (SH2 domain) have been described with a high frequency of 40% in T-cell LGL (T-LGL) leukemia (Koskela et al., 2012) and 30% in chronic NK-cell lymphoproliferative disorder (CLPD-NK) (Jerez et

Real-time simulation of complex audio-visual scenes remains challenging due to the technically independent but perceptually related rendering process in each modality. Because of the potential crossmodal dependency of auditory and visual perception, the optimization of graphics and sound rendering, such as Level of Details (LOD), should be considered in a combined manner but not as separate issues. For instance, in audition and vision, people have perceptual limits on observation quality. Techniques of perceptually driven LOD for graphics have been greatly advanced for decades. However, the co
