TL;DR: In this article, the authors considered nonlinear systems of Timoshenko type in a one-dimensional bounded domain with a dissipative mechanism being present only in the equation for the rotation angle; it is a damping effect through heat conduction.

TL;DR: Democracies are Janus-faced as discussed by the authors, and they are frequently involved in militarized disputes and wars with authoritarian regimes, while they do not fight each other, they are often involved in military conflicts.
Abstract: Democracies are Janus-faced. While they do not fight each other, they are frequently involved in militarized disputes and wars with authoritarian regimes. The article argues that these two empirica...

TL;DR: In this paper, the authors showed that polyethylene-like materials with a low density of in-chain functional groups as break points can be recycled chemically by solvolysis with a recovery rate of more than 96 per cent.
Abstract: Plastics are key components of almost any technology today. Although their production consumes substantial feedstock resources, plastics are largely disposed of after their service life. In terms of a circular economy1–8, reuse of post-consumer sorted polymers (‘mechanical recycling’) is hampered by deterioration of materials performance9,10. Chemical recycling1,11 via depolymerization to monomer offers an alternative that retains high-performance properties. The linear hydrocarbon chains of polyethylene12 enable crystalline packing and provide excellent materials properties13. Their inert nature hinders chemical recycling, however, necessitating temperatures above 600 degrees Celsius and recovering ethylene with a yield of less than 10 per cent3,11,14. Here we show that renewable polycarbonates and polyesters with a low density of in-chain functional groups as break points in a polyethylene chain can be recycled chemically by solvolysis with a recovery rate of more than 96 per cent. At the same time, the break points do not disturb the crystalline polyethylene structure, and the desirable materials properties (like those of high-density polyethylene) are fully retained upon recycling. Processing can be performed by common injection moulding and the materials are well-suited for additive manufacturing, such as 3D printing. Selective removal from model polymer waste streams is possible. In our approach, the initial polymers result from polycondensation of long-chain building blocks, derived by state-of-the-art catalytic schemes from common plant oil feedstocks, or microalgae oils15. This allows closed-loop recycling of polyethylene-like materials. Polycarbonates and polyesters with materials properties like those of high-density polyethylene can be recycled chemically by depolymerization to their constituent monomers, re-polymerization yielding material with uncompromised processing and materials properties.

TL;DR: It is indicated that TLR-2 is the main receptor for Treponema glycolipid and LTA-mediated inflammatory response and involvement of the signaling molecules MyD88 and NIK in cell stimulation by LTAs and Glycolipids by dominant negative overexpression experiments is shown.

TL;DR: Memory performance and the oscillatory correlates of memory formation crucially depend on the overlap of the context between encoding and test, and context-dependent episodic memory effects are mediated by theta oscillatory activity for the first time.
