This chapter analyses Marvell’s linguistic ingenuity as exemplified by his Latin poetic corpus. Here, it is argued, a pseudo Lucretian sensitivity to the parallelism between the structure of Latin words and the structure of the world co-exists with a linguistic methodology that is essentially Marinesque. Close examination of the Latin poems as a whole assesses the nature and significance of etymological play, paronomasia, puns on juxtaposed Latin words, on place names, and on personal names. It is suggested that such devices demonstrate ways in which the neo-Latin poetic text can serve both as a linguistic microcosm of the literary contexts in which they are employed, and as a re-invention of the artifice, extravagant conceits, and baroque wit of Marinism. The result is a neo-Latin ‘echoing song’ that is both intra- and intertextual. Through bilingual punning and phonological wit Marvell plays with a classical language only to demonstrate its transformative potential. The chapter concludes by offering a new reading of Hortus in relation to the garden sections of Marino’s L’Adone, in which an extravagantly luscious setting confounds the senses and is mirrored linguistically by word-clusters and labyrinthine punning.

The particular microenvironment of the skeletal muscle can be the site of complex immune reactions. Toll-like receptors (TLRs) mediate inflammatory stimuli from pathogens and endogenous danger signals and link the innate and adaptive immune system. We investigated innate immune responses in human muscle. Analyzing TLR1-9 mRNA in cultured myoblasts and rhabdomyosarcoma cells, we found constitutive expression of TLR3. The TLR3 ligand Poly (I:C), a synthetic analog of dsRNA, and IFN-gamma increased TLR3 levels. TLR3 was mainly localized intracellularly and regulated at the protein level. Poly (I:C) challenge 1) activated nuclear factor-kappaB (NF-kappaB), 2) increased IL-8 release, and 3) up-regulated NKG2D ligands and NK-cell-mediated lysis of muscle cells. We examined muscle biopsy specimens of 6 HIV patients with inclusion body myositis/polymyositis (IBM/PM), 7 cases of sporadic IBM and 9 nonmyopathic controls for TLR3 expression. TLR3 mRNA levels were elevated in biopsy specimens from patients with IBM and HIV-myopathies. Muscle fibers in inflammatory myopathies expressed TLR3 in close proximity of infiltrating mononuclear cells. Taken together, our study suggests an important role of TLR3 in the immunobiology of muscle, and has substantial implications for the understanding of the pathogenesis of inflammatory myopathies or therapeutic interventions like vaccinations or gene transfer.

As modern power grids move towards becoming a smart grid, there is an increasing reliance on the data that is transmitted and processed by ICT systems. This reliance introduces new digital attack vectors. Many of the proposed approaches that aim to address this problem largely focus on applying well-known ICT security solutions. However, what is needed are approaches that meet the complex concerns of the smart grid as a cyber-physical system. Furthermore, to support the automatic control loops that exist in a power grid, similarly automatic security and resilience mechanisms are needed that rely on minimal operator intervention. The research proposed in this paper aims to develop a framework that ensures resilient smart grid operation in light of successful cyber-attacks.
