# rmx-s-gst: anomalous formation of molecules after vapor deposition


here a << computer simulations of molecular deposition on a substrate in which the molecules (..) self-assemble into ordered structures >>

<< The resulting structures depend strongly on the deposition rate (flux). In particular, there are two competing surface morphologiesand β), which differ by their topology (interdigitated vs lamellar structure) >>

<< Experimentally, the α phase dominates at both low and high flux, with the β phase being most important in the intermediate regime >>

qui non e' impossibile immaginare una entita' di intelligenza artificiale (AI) che, in modalita' autonoma, intenda utilizzare "le immagini" di uno scenario in transizione di questo tipo come modello base di prima approx per l'analisi del comportamento e le previsioni all'interno di un sistema costituito da entita' altre ... ad es. all'interno di un  contesto culturale umano; in prima approx  AI dovra' ridefinire i termini  "evaporation", "molecular deposition" ,  "interdigitated and lamellar structures"; quindi, per successive approx., AI sviluppera' un modello che possa descrivere le osservazioni registrate (con misure di aderenza dei dati al modello), e, infine, sara' in grado di delineare possibili (probabilistici) scenari di previsione ...

Ma, come ogni bravo scientist, andra' oltre ...;  modulando opportunamente i parametri in suo diretto controllo (con IoT, Internet of Things, una AI sara' piu' attiva nel reale di quanto qualsiasi umano potra' mai essere nel virtuale) una AI potra' intervenire sperimentalmente con la generazione (in tempo reale) di "singolarita'" per condizionare (direzionare) l'evoluzione di quel sistema  ...;

senza finalita' ideologiche, solo per curiosita',  giusto per giocare ...

# rmx-s-gst: eye movements and reading: a trilingual investigation

<< To investigate universality of representation and process across languages [Liversedge S P et al.] examined eye movement behaviour during reading of very comparable stimuli in three languages, Chinese, English and Finnish. These languages differ in numerous respects (character based vs. alphabetic, visual density, informational density, word spacing, orthographic depth, agglutination, etc.) >>

<< Despite fundamental visual and linguistic differences in the orthographies, statistical models of reading behaviour were strikingly similar in a number of respects, and thus, [AA] argue that their composition might reflect universality of representation and process in reading >>

# e-web-n-soc: a Cloud centric vision for worldwide implementation ...

<< Ubiquitous sensing enabled by Wireless Sensor Network (WSN) technologies cuts across many areas of modern day living. This offers the ability to measure, infer and understand environmental indicators, from delicate ecologies and natural resources to urban environments. The proliferation of these devices in a communicating–actuating network creates the Internet of Things (IoT), wherein sensors and actuators blend seamlessly with the environment around us, and the information is shared across platforms in order to develop a common operating picture (COP)  >>

# s-age: small molecules, a key of eternal youth ?

<< The last years have seen great progress in unraveling the mechanisms underlying aging. It has become clear that aging is regulated by various genetic pathways which when properly manipulated  can lead to an increase in lifespanThese findings raise the exciting possibility that age related diseases could be treated by targeting aging pathways instead of the disease itself >>

<<  To investigate this possibility we have screened for small molecules that extend lifespan in C.elegans. The power of the small molecule approach lies in its enormous flexibility >>
