Corrado Segre. Lezioni inedite di due corsi universitari
No full textFra i maggiori artefici del ‘risorgimento geometrico in Italia’, Segre offre uno degli esempi più alti del ruolo di maestro nella storia della matematica. I suoi corsi universitari sono una vera fucina di futuri ricercatori. La migliore testimonianza del suo duplice ruolo di caposcuola e di educatore è rappresentata dai 40 quaderni manoscritti in cui sviluppava con cura, ogni estate, l’argomento del corso che avrebbe tenuto nell’autunno successivo. Emblematici sono i due quaderni che qui presentiamo, che raccolgono rispettivamente le lezioni del corso di Geometria superiore del 1890-91 e quelle del Corso di matematica che Segre tenne per quasi vent’anni alla Scuola di Magistero dell’Università di Torino. Il primo, dedicato alla geometria sulla curva algebrica, costituisce la base della sua fondamentale memoria del 1894, "Introduzione alla geometria sopra un ente algebrico semplicemente infinito", che, come scrive l’allievo Francesco Severi, contiene ‘le radici’ della geometria algebrica italiana. Nel secondo, Segre, partendo da alcune considerazioni sulla natura della matematica, sugli scopi dell’insegnamento, sull’importanza dell’intuizione e sul rigore, propone un approccio innovativo alla formazione degli insegnanti, legato da un lato al suo modo peculiare di fare ricerca e frutto, dall’altro, di un attento esame delle recenti riforme e delle problematiche didattiche dibattute in Europa
Modelling orexinergic system in ageing in the African turquoise killifish
No full text: The orexinergic system is anatomically and functionally conserved in almost all vertebrates, and the role in healthy ageing and age-associated diseases has been studied in mammals. Here, we review the main findings on the age-related regulation of orexinergic system in mammals, including human patients and highlights how the fish Nothobranchius furzeri serves as an exceptional model to spearhead research and unravel the intricate mechanisms underlying orexinergic regulation during ageing. The ageing brain of this teleost is characterized by the presence of neurodegenerative processes similar to those associated with human pathologies rather than those of healthy ageing. We present an in-depth summary and discussion on the groundbreaking advances in understanding the neuroanatomical organization of the orexinergic system, its pivotal role in mammalian and fish models, and its profound involvement in healthy ageing and age-associated diseases
Portraits of Livia in Asia Minor
No full textBu çalışmada, Roma İmparatorluğu'nun doğudakien önemli eyaletlerinden birisi olan Küçük Asya'da elegeçmiş Livia portreleri tipolojik acıdan ele alınacaktır.Söz konusu eserler, bugüne kadar Livia portrelerinikonu alan birçok çalışmada ele alınmıştır. Ancak konuile ilgili en kapsamlı ve güncel yayın, E. Bartman'a aittir.Araştırmacı yayınında adı geçen coğrafyadaki portreleri Marbury Hall tipinin birer varyantı olarak kabuletmiştir. Ancak tarafımızca yapılan gözlemler, bu portrelerin Fayumtipini de ayırt edici özelliklerine sahip olduklarını ve hatta bu iki tipe yabancı unsurları da taşıdıklarını ortaya koymuştur. Makalede öncelikli olarakbu iki tipin ayırt edici özelliklerinden bahsedilecek, ardından Küçük Asya eserlerinin bu tiplerin hangi özellik/özelliklerine sadık kalınarak uygulama bulduğu üzerinde durulacak ve yabancı unsurlar için de önerilersunulacaktır.This article treats from a typological perspective the portraits of Livia, portraits originating from the major eastern provinces of the Roman Empire, as also from Asia Minor. These portraits have already been analysed in scholarly works. In this respect E. Bartman has presented the most recent and comprehensive scientific analysis. The author has stated that the portraits in question were variants of the Marbury Hall statuary type. However, observation shows these portraits carry the characteristics of more than one portrait-type, for example of the Fayum type. In addition, they have completely different elements from this type. The following article first addresses the differences between the two types and subsequently, the question is discussed, as to which characteristics of these types can be observed in the Livia portraits fromAsia Minor. Finally, the postulated different elements arestated
Developing an open access croplands research database through global collaboration
No full textThis article describes the processes, challenges, and outcomes of a project undertaken by Kansas State University (K-State) Libraries and a global community of researchers. The project, initiated by
librarians in the newly created Faculty and Graduate Services Department, involved collaboration with a K-State agronomist. The
initial concept was to create an open access database of croplands research submitted by researchers from the Global Research
Alliance Croplands Research Group, a consortium of over 30 countries. Due to the project’s complexity, it was determined that a more manageable approach would be to pilot the project by including research from only the United States and Australia to resolve problems before scaling up to include all 34 countries in the GRA Croplands Research Group

Livia: Data-Centric Computing Throughout the Memory Hierarchy
No full text© 2020 Copyright held by the owner/author(s). Publication rights licensed to ACM. In order to scale, future systems will need to dramatically reduce data movement. Data movement is expensive in current designs because (i) traditional memory hierarchies force computation to happen unnecessarily far away from data and (ii) processing-in-memory approaches fail to exploit locality. We propose Memory Services, a flexible programming model that enables data-centric computing throughout the memory hierarchy. In Memory Services, applications express functionality as graphs of simple tasks, each task indicating the data it operates on. We design and evaluate Livia, a new system architecture for Memory Services that dynamically schedules tasks and data at the location in the memory hierarchy that minimizes overall data movement. Livia adds less than 3% area overhead to a tiled multicore and accelerates challenging irregular workloads by 1.3× to 2.4× while reducing dynamic energy by 1.2× to 4.7×
Mirror Acts: Dramatic Form in Pirandello’s Six Characters in Search of an Author and Beckett’s Waiting for Godot
No full textPirandello is among the first playwrights to reshape the very notion of theatre and pave the way for a postmodern understanding of the human. By fixing one of drama’s cardinal axes—space—and making it simultaneously literal and inherently static—Pirandello frees the other—time—thereby undoing the core of the dramatic arc. This simple shift repositions both plot and characters, placing them in a cosmology which tauntingly ignores them. Their experience—and by extension the human experience—becomes inherently aimless. In this latter light, Pirandello’s characters are an anticipation of Beckett’s. While this is indubitably an important point of contact between the two, it is the similarity in their structural redefinition of spacetime, that allows both to pave the way for a pivotal revolution of form that will bloom in the works of their heirs—Pinter and Stoppard, primarily—and anticipate postdramatic theatre. In this light, Six Characters in Search of an Author, first staged in Rome and Paris in 1921 a time when Beckett would have been exposed to a response to it, plants a lasting seed
