Origini ed evoluzione del sistema centralizzato ad Arslantepe: dal tempio al palazzo nel IV millennio A.C.

This article reconsiders the nature of the development of a highly centralised political and economic structure at Arslantepe at the end of the fourth millennium BC (period VI A) in the light of a recent discovery of a huge ceremonial building from the middle of the 4th millennium (period VII), which stresses the importance of local components. This earlier building has a tripartite layout that clearly recalls a typical Mesopotamian architecture typology, but the archaeological materials show completely and exclusively local characteristics, without any evidence of Uruk influence. On the other hand, the main activity performed in this building, which seems to be a temple or ceremonial structure, was redistribution carried out under an administrative control, as is suggested by hundreds of mass-produced bowls and numerous clay-sealings. The development of the Arslantepe period VI A society, expressed in what appears to be the first example in the Near East of a "palace" complex, in this perspective, should be seen as a local and original evolution from earlier developments shared with other regions of Greater Mesopotamia, rather than the effect of an emulation of foreign communitie

Collapse or transformation? Regeneration and innovation at the turn of the first millennium BC at Arslantepe, Turkey

Ongoing excavations at Arslantepe in south-eastern Turkey are revealing settlement continuity spanning two crucial phases at the transition from the second to the first millennium BC: the post-Hittite period and the development of Syro-Anatolian societies

Light controlled motility of Escherichia coli. Characterization and applications

Characterization of wild type E. coli motility in response to light stimuli. Gene editing of bacteria to implement specifc functions (e.g. photokinesis). The engineered strain has been used to demonstrate that density modulation of photokinetic bacteria can be obtained by projecting spatially structured light on the sample. Additionally these bacteria have been also used as propelling units in microfabricated structures

Invariance properties of bacterial random walks in complex structures

Motile cells often explore natural environments characterized by a high degree of structural complexity. Moreover cell motility is also intrinsically noisy due to spontaneous random reorientation and speed fluctuations. This interplay of internal and external noise sources gives rise to a complex dynamical behavior that can be strongly sensitive to details and hard to model quantitatively. In striking contrast to this general picture we show that the mean residence time of swimming bacteria inside artificial complex microstructures, can be quantitatively predicted by a generalization of a recently discovered invariance property of random walks. We find that variations in geometry and structural disorder have a dramatic effect on the distributions of path length while mean values are strictly constrained by the sole free volume to surface ratio. Biological implications include the possibility of predicting and controlling the colonization of complex natural environments using only geometric informations

Optimal use of Charge Information for the HL-LHC Pixel Detector Readout

The pixel detectors for the High Luminosity upgrades of the ATLAS and CMS detectors will preserve digitized charge information in spite of extremely high hit rates. Both circuit physical size and output bandwidth will limit the number of bits to which charge can be digitized and stored. We therefore study the effect of the number of bits used for digitization and storage on single and multi-particle cluster resolution, efficiency, classification, and particle identification. We show how performance degrades as fewer bits are used to digitize and to store charge. We find that with limited charge information (4 bits), one can achieve near optimal performance on a variety of tasks.Comment: 27 pages, 20 figure

Strutturazione multimediale di un testo di riferimento per lo studio della storia della citt\ue0 di Udine e dei suoi edifici, redatto nella prima met\ue0 del \u2018900, da G.B. della Porta (1873\u20131954), di cui sfrutta la valenza di strumento GIS per la conoscenza del patrimonio costruito. Si tratta del risultato di un\u2019attivit\ue0 di ricerca pluriennale, un "archivio aperto\u201d, che permette una fruizione interattiva del testo, tra case, disegni e documenti, configurando uno spazio di integrazione delle fonti, spazio virtuale condiviso per la tutela della memoria dei luoghi. | Multimedia set-up of a "cult" text for the study of the town of Udine and of its buildings. The text, written by G.B. della Porta in the first part of the 20th century, hides a GIS valence, which has been revealed by the author, aiming in providing a new tool for the knowledge of the built heritage. The web site is the result of a research work many years long. It envisages an "open archive", allowing the interactive fruition of the text, among houses, drawings and writings. It provides an integration space of sources, shared toward the preservation of the memory of sites
