Sandpile groups and the coeulerian property for random directed graphs [PDF]
arXiv, 2016 We consider random directed graphs, and calculate the distribution of the cokernels of their laplacian, following the methods used by Wood. As a corollary, we show that the probability that a random digraph is coeulerian is asymptotically upper bounded by a constant around $0.43$.

Advanced Healthcare Materials, EarlyView.Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.

Normalization Before Shaking Toward Learning Symmetrically Distributed Representation Without Margin in Speech Emotion Recognition [PDF]
arXiv, 2018 Regularization is crucial to the success of many practical deep learning models, in particular in a more often than not scenario where there are only a few to a moderate number of accessible training samples. In addition to weight decay, data augmentation and dropout, regularization based on multi-branch architectures, such as Shake-Shake ...

Synthetic Aspects and Characterization Needs in MOF Chemistry – from Discovery to Applications
Advanced Materials, EarlyView.Overcoming the challenges of phase discovery, synthesis optimization and scale‐up, characterization, and computational studies is essential to accelerate the large‐scale application of MOFs. Life‐cycle analyses and techno‐economic analyses need to be performed to realistically assess their potential for industrial relevance.

Advanced Materials, EarlyView.Stem cell spheroids, produced via a high‐throughput microfabrication technique, are transported within a vortex generated at the outlet channels of a cross‐slot millifluidic chip. For Reynolds number exceeding 170–200, intermittent high shear stresses applied to each spheroid within the vortex trigger a massive release of biologically active ...

Biotechnology Journal, Volume 18, Issue 1, January 2023., 2023 Graphical Abstract and Lay Summary The heterogenous production conditions in large‐scale bioreactors cause scale‐up problems, such as reduced biomass or product yield, to occur during bioprocesses. In this study, we designed a two‐compartment scale‐down reactor and used it to simulate large‐scale heterogenous production conditions, allowing us to ...
