TL;DR: In vitro 3D bioprinted blood coagulation models can be used to study the pathology of fibrosis, and particularly, in thrombosis, and this versatile platform may be conveniently extended to other vascularized fibrotic disease models.
Abstract: Pathologic thrombosis kills more people than cancer and trauma combined; it is associated with significant disability and morbidity, and represents a major healthcare burden. Despite advancements in medical therapies and imaging, there is often incomplete resolution of the thrombus. The residual thrombus can undergo fibrotic changes over time through infiltration of fibroblasts from the surrounding tissues and eventually transform into a permanent clot often associated with post-thrombotic syndrome. In order to understand the importance of cellular interactions and the impact of potential therapeutics to treat thrombosis, an in vitro platform using human cells and blood components would be beneficial. Towards achieving this aim, there have been studies utilizing the capabilities of microdevices to study the hemodynamics associated with thrombosis. In this work, we further exploited the utilization of 3D bioprinting technology, for the construction of a highly biomimetic thrombosis-on-a-chip model. The model consisted of microchannels coated with a layer of confluent human endothelium embedded in a gelatin methacryloyl (GelMA) hydrogel, where human whole blood was infused and induced to form thrombi. Continuous perfusion with tissue plasmin activator led to dissolution of non-fibrotic clots, revealing clinical relevance of the model. Further encapsulating fibroblasts in the GelMA matrix demonstrated the potential migration of these cells into the clot and subsequent deposition of collagen type I over time, facilitating fibrosis remodeling that resembled the in vivo scenario. Our study suggests that in vitro 3D bioprinted blood coagulation models can be used to study the pathology of fibrosis, and particularly, in thrombosis. This versatile platform may be conveniently extended to other vascularized fibrotic disease models.

TL;DR: The authors investigated the relationship between investment and regulatory regimes (incentive vs. rate-of-return regulation) for a sample of EU energy utilities from 1997 to 2007, and found that investment of incentive regulated firms appears highly sensitive to the X factor, consistent with efficiency and profit-seeking motivations.
Abstract: This paper investigates the relationship between investment and regulatory regimes (incentive vs. rate-of-return regulation) for a sample of EU energy utilities from 1997 to 2007. We control for the effect of firm ownership and for cross-country differences in the underlying energy demand and energy supply. To deal with potential endogeneity of the regulatory regime, we apply instrumental variable methods (2SLS and GMM). Our results show that investment rate is higher under incentive regulation than under rate of return regulation. Using original data on the regulatory tools (X factor and WACC), we find that investment of incentive regulated firms appears highly sensitive to the X factor, consistent with efficiency- and profit-seeking motivations. Electric utilities investment is also sensitive to the level and change in the weighted average cost of capital (WACC). Finally, we find that the positive relationship between private control and investment is not robust to IV estimations, suggesting that in Europe regulation may have reduced the differences between private and public firms’ incentives to invest.

TL;DR: In this paper, a comparative study of machining of Ti6Al4V alloy under dry, minimal quality lubrication, and cryogenic cooling conditions using coated tools at varying cutting speeds and feed rates is presented.
Abstract: This paper presents results from a comparative study of machining of Ti6Al4V alloy under dry, minimal quality lubrication, and cryogenic cooling conditions using coated tools at varying cutting speeds and feed rates. The influence of the cooling conditions on surface integrity and the product performance was studied in terms of surface roughness, metallurgical conditions, including microstructure, hardness, grain refinement, and phase transformation of the machined product. Results show that cooling conditions affect surface integrity of the product signifying the benefits of cryogenic cooling in improving the overall product performance.

TL;DR: This paper deals with the modeling and simulation of swarms viewed as a living, hence complex, system based on methods of kinetic theory and statistical mechanics and modeled by stochastic games.
Abstract: This paper deals with the modeling and simulation of swarms viewed as a living, hence complex, system. The approach is based on methods of kinetic theory and statistical mechanics, where interactions at the microscopic scale are nonlinearly additive and modeled by stochastic games.
