Future access networks are converged optical-wireless networks, where fixed-line and wireless services share the same infrastructure. In this book, semiconductor optical amplifiers (SOA) and mm-wave wireless links are investigated, and their use in converged access networks is explored: SOAs compensate losses in the network, and thereby extend the network reach. Millimeter-wave wireless links substitute fiber links when cabling is not economical.

Emotions play a central role in every human life, from the moment we are born until we die. They prepare the body for action, guide decisions, and highlight what should be noticed and remembered. Since emotions are central to daily functioning and well-being, it is important to understand the extent to which aging affects the perception of, attention to, memory for, as well as experience and regulation of emotions.An early scientific view of how people's emotions are affected by aging argued that aging led to a deterioration of emotional function. This theory, represented by for example Carl Jung (1875-1961), claimed that old age is a period of life when people feel an increased emotional sameness and less emotional energy. According to this scientific view, the aging emotional landscape was bleached, barren, and flattened. Current psychological research, however, shows that emotion is rather a psychological domain that is relatively unaffected by the aging process or even improves with age, in contrast to most cognitive functions. For example, even though there is evidence that aging is associated with deficits in emotion recognition, various emotional functions seem to remain intact or become better with age, such as the ability to regulate one’s emotions or the extent of experiencing positive emotions. However, more research is needed to determine brain and behavior related, quantitative and qualitative age-related changes of different aspects of emotion processing and emotional functioning.In the current Frontiers research topic we aim to present exciting new findings related to the effects of healthy aging on both more perceptually driven bottom-up as well as more cognitively driven top-down aspects of emotions. In particular, questions such as the following need to be raised and addressed: What neural and behavioral processes are underlying age differences in emotion perception and memory for emotional information? Are there differences between how older and younger adults experience and regulate their emotions, and what drives these differences? Is there a gradual reduction or more of a qualitative change of our emotional experiences over the life cycle, from the turbulent childhood and youth to the mellower old age? And what aspects of age-related changes in emotional processing can be explained by age-related changes in the brain, and which are more affected by other factors such as changes in other body systems, in experiential processes, or in overall life goals?

This book provides a broad introduction to the physics and technology of the High Luminosity Large Hadron Collider (HL-LHC). This new configuration of the LHC is one of the major accelerator projects for the next 20 years and will give new life to the LHC after its first 15-year operation. Not only will it allow more precise measurements of the Higgs boson and of any new particles that might be discovered in the next LHC run, but also extend the mass limit reach for detecting new particles. The HL-LHC is based on the innovative accelerator magnet technologies capable of generating 11–13 Tesla fields, with effectiveness enhanced by use of the new Achromatic Telescopic Squeezing scheme, and other state-of-the-art accelerator technologies, such as superconducting compact RF crab cavities, advanced collimation concepts, and novel power technology based on high temperature superconducting links.The book consists of a series of chapters touching on all issues of technology and design, and each chapter can be read independently. The first few chapters give a summary of the whole project, of the physics motivation and of the accelerator challenges. The subsequent chapters cover the novel technologies, the new configurations of LHC and of its injectors as well as the expected operational implications. Altogether, the book brings the reader to the heart of technologies for the leading edge accelerator and gives insights into next generation hadron colliders.

The rapid proliferation of the Internet has been driving communication networks closer and closer to their limits, while available bandwidth is disappearing due to an ever-increasing network load. Over the past decade, optical fiber communication technology has increased per fiber data rate from 10 Tb/s to exceeding 10 Pb/s. The major explosion came after the maturity of coherent detection and advanced digital signal processing (DSP). DSP has played a critical role in accommodating channel impairments mitigation, enabling advanced modulation formats for spectral efficiency transmission and realizing flexible bandwidth. This book aims to explore novel, advanced DSP techniques to enable multi-Tb/s/channel optical transmission to address pressing bandwidth and power-efficiency demands. It provides state-of-the-art advances and future perspectives of DSP as well.

I saggi raccolti in Dentro e fuori il testo rappresentano una sintetica summa degli studi di Alberto Cadioli, mettendo in risalto alcuni dei passaggi più rilevanti – dal punto di vista teorico-metodologico – di una lunga attività di ricerca. Pur nella varietà e nella dinamicità dei percorsi, queste pagine rivelano la fedeltà a un presupposto che, già individuabile nei primi lavori, è rimasto sempre presente: la vocazione a indagare i nessi che stringono chi crea il testo letterario, chi lo porta alla stampa, chi lo riceve. «Fuori» e «dentro» il testo, dunque, coltivando una critica letteraria che, nelle prime indagini, utilizza gli strumenti della sociologia della letteratura e della storia dell’editoria, e poi via via quelli della filologia, in particolare dei testi a stampa e della filologia d’autore. Dall’editoria alla filologia, dunque, con l’obiettivo di approfondire la storia dei testi e della loro trasmissione, la storia della loro genesi e della mediazione editoriale che li ha portati ai lettori nelle forme di un oggetto storicamente e materialmente definito. Le riflessioni teoriche e le indicazioni metodologiche dei saggi qui proposti hanno spinto Cadioli a percorrere sentieri scarsamente battuti, a suggerire indirizzi di ricerca nuovi sui quali sono cresciuti e consolidati nuovi orientamenti critici, ormai radicati nel panorama degli studi sull’Otto-Novecento letterario.
