The strength of surgical knots involves a critical interplay between friction and elastoplasticity

Pedro Miguel Nunes Pereira de Almeida Reis, Paul Johanns, Paul Grandgeorge, Changyeob Baek

Knots are the weakest link in surgical sutures, serving as mechanical ligatures between filaments. Exceeding their safe operational limits can cause fatal complications. The empirical nature of present guidelines calls for a predictive understanding of the ...

Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials

Dragan Damjanovic, Emad Oveisi, Sina Hashemi Zadeh, Takuya Hoshina

The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery of ferroelectricity in oxide perovskites (ABO3). A currently considered model ...

Additives: Their Influence on the Humidity- and Pressure-Induced Crystallization of Amorphous CaCO3

Esther Amstad, Camelia Borca, Huachuan Du, Mathias Steinacher, Alan Böhlen, Clémence Courrégelongue

Nature possesses a unique control over the formation of CaCO3 crystals that imparts fascinating mechanical properties to many CaCO3-based biomaterials. This high level of control is, at least in part, achieved through the use of certain soluble additives t ...

Learning and leveraging shared domain semantics to counteract visual domain shifts

Róger Bermúdez Chacón

One of the main limitations of artificial intelligence today is its inability to adapt to unforeseen circumstances. Machine Learning (ML), due to its data-driven nature, is particularly susceptible to this. ML relies on observations in order to learn impli ...

Omnidirectional Strategies for Exploring Ancient Cities and Territories

Sarah Irene Brutton Kenderdine

By focusing on technologies of virtual reality in conjunction with theories of “place” and “presence,” this chapter outlines the importance of new approaches to the museological experience and exploration of ancient cities and cultural heritage sites. Expl ...

Water: its influence on the formation and crystallization of amorphous calcium carbonate

Huachuan Du

Nature produces CaCO3-based materials that display fascinating mechanical properties. These properties are a result of the exquisite control over the formation of CaCO3 crystals that nature possesses. Such a high level of control is likely achieved, at lea ...

Reflection: A Socratic approach

Reflection is a fuzzy concept. In this article we reveal the paradoxes involved in studying the nature of reflection. Whereas some scholars emphasize its discursive nature, we go further and underline its resemblance to the self-biased dialogue Socrates ha ...

Epidemics in Venice: On the Small or Large Nature of the Pre-modern World

Giovanni Colavizza

Marvel et al. [12] recently argued that the pre-modern contact world was physically and, by set inclusion, socially not small-world. Since the Black Death and similar plagues used to spread in well-defined waves, the argument goes, the underlying contact n ...

A view on global urbanization : spatial networks, urban scaling and remote sensing

Emanuele Strano

It is widely recognized that global urbanization is one the most urgent issue of our time. Any problem related to global issues, such as climate change, social and environmental sustainability and the future of our society, is somehow related to cities and ...

Models of Reward-Modulated Spike-Timing-Dependent Plasticity

Nicolas Frémaux

How do animals learn to repeat behaviors that lead to the obtention of food or other “rewarding” objects? As a biologically plausible paradigm for learning in spiking neural networks, spike-timing dependent plasticity (STDP) has been shown to perform well ...
