Patterning the Void: Combining L‐Systems with Archimedean Tessellations as a Perspective for Tissue Engineering Scaffolds

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a novel multi‐scale scaffold design using L‐fractals arranged in Archimedean tessellations for tissue regeneration. Despite similar porosity, tiles display vastly different tensile responses (1–100 MPa) and deformation modes. In vitro experiments with hMSCs show geometry‐dependent growth and activity. Over 55 000 tile combinations

Study of the Decay phi --> eta pi0 gamma with the KLOE detector

open access: yes, 2002
In a sample of 5.3x10^7 phi-decays observed with the KLOE detector at the Frascati phi-factory Dafne we find 605 eta pi0 gamma events with eta --> gamma\gamma and 197 eta pi0 gamma events with eta --> pi+ pi- pi0.

High‐Concentration Mesogen‐Assisted Exfoliation of Low‐Dimensional Nanomaterials for Achieving Ultralow‐Temperature Actuations of Liquid Crystal Elastomers

open access: yesAdvanced Functional Materials, EarlyView.
Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Fermin Irigaray «Larreko»: Euskararen maitale

open access: yesFontes Linguae Vasconum, 1994
Gaur egun arte argitaraturiko bildumetan, Larrekoren artikulu anitz jaso dira. Dena den, haietan ez dira berak idatziriko guztiak azaltzen eta horregatik, osagarri bezala, Nafarroako prentsan agerturikoen berri ematea erabaki dugu, Larrekok euskararen ...

Improved Measurements of Branching Fractions and CP Asymmetries in B-> eta h Decays

open access: yes, 2007
We report improved measurements of B decays with an eta meson in the final state using 492 fb^{-1} of data collected by the Belle detector at the KEKB e^+ e^- collider.

chi(c0) and chi(c2) decays into eta eta, eta eta ', and eta 'eta ' final states

open access: yes, 2007
Using a sample of 3x10(6) psi(2S) decays collected by the CLEO III and CLEO-c detector configurations, we present results of a study of chi(c0) and chi(c2) decays into eta eta, eta eta('), and eta(')eta(') final states. We find B(chi(c0)->eta eta)=(0.31 +/- 0.05 +/- 0.04 +/- 0.02)%, B(chi(c0)->eta

The Hierarchical Structure of Sheep Wool and Its Impact on Physical Properties

open access: yesAdvanced Functional Materials, EarlyView.
Sheep wool, a prevalent α‐keratinous fiber, is an essential model for studying protein‐based fibers. Its genetic diversity across breeds enables the establishment of multiscale structure‐property relationships, uncovering previously elusive insights into wool's hierarchical structure.

PT-Symmetric Representations of Fermionic Algebras

open access: yes, 2011
A recent paper by Jones-Smith and Mathur extends PT-symmetric quantum mechanics from bosonic systems (systems for which $T^2=1$) to fermionic systems (systems for which $T^2=-1$).
