Method for patterning a thin film of a solid material

Jürgen Brugger, Giovanni Boero, Xia Liu, Ana Conde Rubio, Samuel Tobias Howell

A method for patterning a thin film of (a) solid material(s), comprising the steps of providing a thin film of said solid material(s) onto a substrate, said substrate being deformable by heat and indentation; and performing a thermo-mechanical indentation ...

The architecture of benthic biofilms - Linking hydraulics to spatially structured processes

Anna Depetris

Biofilms are spatially structured ecosystems, characterized by patterns and architectural features determined by the interplay between endogenous and exogenous processes. As in many other structured ecosystems, the characterization of spatial interactions ...

Dimensionality reduction and clustering of time series for anomaly detection in a supermarket heating system

Roberto Castello, Jean-Louis Scartezzini, Lorenzo Salmina

A timely identification of an anomalous functioning of the energy system of an industrial building would increase the efficiency and the resilience of the energy infrastructure, beside reducing the economic wastage. This work has been inspired by the need ...

Channelization cascade in landscape evolution

Sara Bonetti

The hierarchy of channel networks in landscapes displays features that are characteristic of nonequilibrium complex systems. Here we show that a sequence of increasingly complex ridge and valley networks is produced by a system of partial differential equa ...

Instability of a thin viscous film flowing under an inclined substrate: the emergence and stability of rivulets

François Gallaire, Gioele Mariano Nicolò Balestra, Pier Giuseppe Ledda, Gaëtan Pierre Clément Lerisson

We study the pattern formation of a thin film flowing under an inclined planar substrate. The phenomenon is studied in the context of the Rayleigh-Taylor instability using the lubrication equation. Inspired by experimental observations, we numerically stud ...

Patterning and mechanics of somite boundaries in zebrafish embryos

Andrew Charles Oates, Sundar Ram Naganathan

The body axis of vertebrates is subdivided into repetitive compartments called somites, which give rise primarily to the segmented architecture of the musculoskeletal system in the adult body. Somites form in a sequential and rhythmic manner in embryos and ...

A Muscle-Reflex Model of Forelimb and Hindlimb of Felidae Family of Animal with Dynamic Pattern Formation Stimuli

Auke Ijspeert, Azhar Aulia Saputra

Human and animal locomotion are controlled by complex neural circuits, which can also serve as inspiration for designing locomotion controllers for dynamic locomotion in legged robots. We develop a locomotion controller model including a central pattern ge ...

An overlapping pattern of cerebral cortical thinning is associated with both positive symptoms and aggression in schizophrenia via the ENIGMA consortium

Erick Jorge Canales Rodriguez, Wenhao Jiang

Background Positive symptoms are a useful predictor of aggression in schizophrenia. Although a similar pattern of abnormal brain structures related to both positive symptoms and aggression has been reported, this observation has not yet been confirmed in a ...

Nature of Crack Path Instabilities in Thin Sheets Cut by Blunt Objects

Iryna Sivak

Cutting a brittle thin sheet with a blunt object leaves an oscillating crack that seemingly violates the principle of local symmetry for fracture. We experimentally find that at a critical value of a well chosen control parameter the straight propagation i ...

Waiting on the Fringe: cell autonomy and signaling delays in segmentation clocks

Andrew Charles Oates

The rhythmic and sequential segmentation of the vertebrate body axis into somites during embryogenesis is governed by a multicellular, oscillatory patterning system called the segmentation clock. Despite many overt similarities between vertebrates, differe ...
