Peripheral nerve injuries induce a severe motor and sensory deficit. Since the availability of autologous nerve transplants for nerve repair is very limited, alternative treatment strategies are sought, including the use of tubular nerve guidance conduits(tnGCs). However, the use of tnGCs results in poor functional recovery and central necrosis of the regenerating tissue, which limits their application to short nerve lesion defects(typically shorter than 3 cm). Given the importance of vascularization in nerve regeneration, we hypothesized that enabling the growth of blood vessels from the surrounding tissue into the regenerating nerve within the tnGC would help eliminate necrotic processes and lead to improved regeneration. In this study, we reported the application of macroscopic holes into the tubular walls of silk-based tnGCs and compared the various features of these improved silk^(+) tnGCs with the tubes without holes(silk^(–) tnGCs) and autologous nerve transplants in an 8-mm sciatic nerve defect in rats. Using a combination of micro-computed tomography and histological analyses, we were able to prove that the use of silk^(+) tnGCs induced the growth of blood vessels from the adjacent tissue to the intraluminal neovascular formation. A significantly higher number of blood vessels in the silk^(+) group was found compared with autologous nerve transplants and silk^(–), accompanied by improved axon regeneration at the distal coaptation point compared with the silk^(–) tnGCs at 7 weeks postoperatively. In the 15-mm(critical size) sciatic nerve defect model, we again observed a distinct ingrowth of blood vessels through the tubular walls of silk^(+) tnGCs, but without improved functional recovery at 12 weeks postoperatively. Our data proves that macroporous tnGCs increase the vascular supply of regenerating nerves and facilitate improved axonal regeneration in a short-defect model but not in a critical-size defect model. This study suggests that further optimizatio

This paper presents a dynamic game framework to analyze the role of large banks in interbank markets. By extending existing models, a large bank is incorporated as a dynamic decision-maker interacting with multiple small banks. Using the mean-field game methodology and convex analysis, best-response trading strategies are derived, leading to an approximate equilibrium for the interbank market. The influence of the large bank is investigated on the market stability by examining individual default probabilities and systemic risk, through the use of Monte Carlo simulations. The proposed findings reveal that, when the size of the major bank is not excessively large, it can positively contribute to market stability. However, there is also the potential for negative spillover effects in the event of default, leading to an increase in systemic risk. The magnitude of this impact is further influenced by the size and trading rate of the major bank. Overall, this study provides valuable insights into the management of systemic risk in interbank markets.

Accelerated development of battery technologies heightens an interest in co-locating battery energy storage systems (BESSs) with renewable power plants for stacking of multiple revenue streams such as frequency response services to AC grids. Frequency response market reforms in the UK introduce new end-state services and require evaluating techno-economic feasibility of co-location projects in new circumstances. This paper develops a BESS optimisation method to optimize capacity and operating strategy of a co-located BESS for providing latest Dynamic Containment (DC) services based on the UK perspective. BESS optimisation method simulates BESS delivering DC responses and following operational baselines for state of energy (SoE) restoration, as well as, coordinating with its co-located power plant. Then net present value of BESS co-location project is estimated from power flows across the system and maximised to suggest optimal BESS capacity, target energy footroom and/or headroom levels for baseline estimation, and possible SoE ranges suitable for energy interchange with its co-located power plant. BESS optimisation method is tested based on a particular transmission-level wind farm in the UK and discussed alongside operation and profitability of a BESS co-location project under frequency response market reforms.

numerous soft-sediment deformation structures(SSDS) within thin-bedded, heterolithic lacustrine shoreline deposits of the Upper Triassic Tumble Falls Member, Lockatong Formation of eastern Pennsylvania, demonstrate liquefaction, fluidization and shearing features processes affecting sediment. This study employs thin-section analysis of SSDS to interpret them as probable seismites from the Triassic-Jurassic newark Basin. Sedimentary structures include right-lateral offset of desiccation cracks and ichnofossils, thrust,reverse, and normal faults with mm-scale offsets, horsts and grabens, lateral spreads, and single and complex multiple networks of dikes and sills and associated sedimentary volcanoes, thin mudflows on a paleosurface linked to sediment dikes, load and flame structures, ball and pillow structures, recumbent folds, and incipient breccias. Dike fill consists of mudstone, angular sedimentary clasts, sandstone margins with mudstone cores,and plastically deformed sediment fill. The SSDS indicate that Late Triassic lacustrine shoreline sediments were subjected to forces, probably compressive with a minimal shear component reflected in the offset of the dikes and ichnofossils, that induced liquefaction followed by fluidization and vertical movement of *** forces that altered sediment vertical stability, leading to deformation of the sediment included gravitationally unstable density gradients, vertical shear stress, and gravitational body forces. SSDS can be induced by seismic and aseismic processes. However, this unique combination of forces and resulting sedimentary structures indicate an origin by earthquake activity, likely produced by the nearby, active newark Basin border fault system. The Lockatong Formation SSDS seismites improve our understanding via thin section analysis of the rheology and preservation potential of SSDS in lacustrine shoreline deposits, critical for the geologic history of newark Basin, as well as the refinement for paleos
