Universal Intrinsic Spin Hall Effect [PDF]

Physical Review Letters, 2004
We describe a new effect in semiconductor spintronics that leads to dissipationless spin-currents in paramagnetic spin-orbit coupled systems. We argue that in a high mobility two-dimensional electron system with substantial Rashba spin-orbit coupling, a spin-current that flows perpendicular to the charge current is intrinsic.

The structure of communication problems in cellular automata [PDF]

Discrete Mathematics & Theoretical Computer Science, 2011
Studying cellular automata with methods from communication complexity appears to be a promising approach. In the past, interesting connections between communication complexity and intrinsic universality in cellular automata were shown.

African recognition of dignity as a basis for universal human rights

Acta Academica, 2023
I present a typically African account of human dignity, which I derive from Ifeanyi Menkiti’s influential strongly normative view of traditional African practices of recognition respect (2004). I explain how this implies a suitable basis for a common

Transition between chaotic and stochastic universality classes of kinetic roughening

Physical Review Research, 2021
The dynamics of nonequilibrium spatially extended systems are often dominated by fluctuations, e.g., due to deterministic chaos or intrinsic stochasticity.

Distance learning in higher education during COVID-19: The role of basic psychological needs and intrinsic motivation for persistence and procrastination-a multi-country study.

PLoS ONE, 2021
Due to the COVID-19 pandemic, higher educational institutions worldwide switched to emergency distance learning in early 2020. The less structured environment of distance learning forced students to regulate their learning and motivation more ...

The Tile Assembly Model is Intrinsically Universal [PDF]

2012 IEEE 53rd Annual Symposium on Foundations of Computer Science, 2012
We prove that the abstract Tile Assembly Model (aTAM) of nanoscale self-assembly is intrinsically universal. This means that there is a single tile assembly system U that, with proper initialization, simulates any tile assembly system T. The simulation is "intrinsic" in the sense that the self-assembly process carried out by U is exactly that carried ...

The Humble Reason. On Education in Kant and Fichte

Ethics in Progress, 2021
In this paper I will focus on education as the core function of reason in Kant and Fichte. The notion of reason carries an intrinsic tendency to universality, which is difficult to be reconciled with its local (cultural, historical, anthropological ...

Unsupervised Learning Universal Critical Behavior via the Intrinsic Dimension [PDF]

Physical Review X, 2021
The identification of universal properties from minimally processed data sets is one goal of machine learning techniques applied to statistical physics. Here, we study how the minimum number of variables needed to accurately describe the important features of a data set - the intrinsic dimension ($I_d$) - behaves in the vicinity of phase transitions ...

Geometric Phase in Twisted Topological Complementary Pair

Advanced Science, 2023
Geometric phase enabled by spin‐orbit coupling has attracted enormous interest in optics over the past few decades. However, it is only applicable to circularly‐polarized light and encounters substantial challenges when applied to wave fields lacking the

The problem of subjectivity of values in the search for a universal environmental ethics

Heritage and Sustainable Development, 2021
Considering the relationship between the environment and morality, discussion of the matter of values is inevitable. Although there is no consensus on the intrinsic and instrumental characteristics of the value, the condition of talking about ...
