Asymmetry of the Ferroelectric Phase Transition in BaTiO3

open access: yesAdvanced Materials, EarlyView.
Phase transitions are typically assumed to behave identically in forward and reverse. This work shows that in the ferroelectric material barium titanate this is not true: heating drives an abrupt, first‐order jump, while cooling gives a smooth, continuous change.

Why Color-Flavor Locking is Just like Chiral Symmetry Breaking [PDF]

open access: yes, 1999
We review how a classification into representations of color and flavor can be used to understand the possible patterns of symmetry breaking for color superconductivity in dense quark matter.

Symmetry properties of Penrose type tilings

open access: yes, 2008
The Penrose tiling is directly related to the atomic structure of certain decagonal quasicrystals and, despite its aperiodicity, is highly symmetric. It is known that the numbers 1, $-\tau $, $(-\tau)^2$, $(-\tau)^3$, ..., where $\tau =(1+\sqrt{5})/2 ...

A Female‐Locust‐Inspired Hybrid Soft‐Stiff Robotic Digger: Mimetics and Implications for Digging Efficiency

open access: yesAdvanced Intelligent Systems, EarlyView.
Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up

The Many Faces of a Character

open access: yes, 1993
We prove an identity between three infinite families of polynomials which are defined in terms of `bosonic', `fermionic', and `one-dimensional configuration' sums.

Impact of Rapid Exome Sequencing on Pediatric Patients With Cardiomyopathy and Acute Heart Failure

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Few studies describe the impact of rapid exome sequencing (ES) on pediatric cardiomyopathy in urgent clinical settings. Here, we retrospectively report the impact of rapid singleton ES in pediatric patients presented with acute heart failure and isolated cardiomyopathy or myocarditis, between 2021 and 2023 at a single tertiary care center.

Ethnic segregation in Tel-Aviv - Jaffa

open access: yesDela, 2004
In the article analysis of the segregation of 1000 representatives of eight important ethnic groups in Tel-Aviv – Jaffa is represented. The comparison of results was made on the basis of index of dissimilation.

Dialogical structures in 17th century controversies [PDF]

open access: yes, 2006
This article is a contribution to historical dialogue analysis, a field of research which has gained momentum in recent years (Fritz 1995, 1997, Gloning 1999, and other articles in Jucker/Fritz/Lebsanft 1999).

Mapping quantitative trait loci underlying body weight changes that act at different times during high‐fat diet challenge in collaborative cross mice

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Over one billion people worldwide suffer from obesity, and the number is continually rising. Animal models, especially mouse models, are crucial to identifying the genetic components of complex disorders and exploring the potential applications of these genetic findings.
