Opisy zwierząt na przykładzie lwa w Bestiariuszu Philippe’a de Thaon [PDF]

open access: yes, 2019
Philippe de Thaon był klerykiem piszącym w pierwszej ćwierci XII w. Pozostawił po sobie teksty o tematyce przyrodniczej, wśród których wyróżnić należy pierwszy francuskojęzyczny bestiariusz. Pierwszym opisanym w nim zwierzęciem jest lew.

Emergent magnetic state in (111)-oriented quasi-two-dimensional spinel oxides

open access: yes, 2019
We report on the emergent magnetic state of (111)-oriented CoCr2O4 ultrathin films sandwiched by Al2O3 in the quantum confined geometry. At the two-dimensional crossover, polarized neutron reflectometry reveals an anomalous enhancement of the total ...

Manipulating spins of magnetic molecules: Hysteretic behavior with respect to bias voltage [PDF]

open access: yes, 2018
Formation of a magnetic hysteresis loop with respect to a bias voltage is investigated theoretically in a spin-valve device based on a single magnetic molecule. We consider a device consisting of two ferromagnetic electrodes bridged by a carbon nanotube,

Evidence for a Bulk Complex Order-Parameter in Y0.9Ca0.1Ba2Cu3O7-delta Thin Films

open access: yes, 2004
We have measured the penetration depth of overdoped Y0.9Ca0.1Ba2Cu3O7-delta (Ca-YBCO) thin films using two different methods. The change of the penetration depth as a function of temperature has been measured using the parallel plate resonator (PPR ...

Aluminium-oxide wires for superconducting high kinetic inductance circuits [PDF]

open access: yes, 2016
We investigate thin films of conducting aluminium-oxide, also known as granular aluminium, as a material for superconducting high quality, high kinetic inductance circuits. The films are deposited by an optimised reactive DC magnetron sputter process and

The effect of cattle slurry in combination with nitrate and the nitrification inhibitor dicyandiamide on in situ nitrous oxide and dinitrogen emissions [PDF]

open access: yes, 2012
peer-reviewedA field study was conducted to determine the effect of the nitrification inhibitor dicyandiamide (DCD) on N2O and N2 emissions after cattle slurry (CS) application in the presence of nitrate (NO3) fertiliser on seven different occasions ...

Zitterbewegung of a heavy hole in presence of spin-orbit interactions

open access: yes, 2015
We study the $zitterbewegung$ of a heavy hole in presence of both cubic Rashba and cubic Dresselhaus spin-orbit interactions. On contrary to the electronic case, $zitterbewegung$ does not vanish for equal strength of Rashba and Dresselhaus spin-orbit ...

Interactions and screening in gated bilayer graphene nanoribbons

open access: yes, 2010
The effects of Coulomb interactions on the electronic properties of bilayer graphene nanoribbons (BGNs) covered by a gate electrode are studied theoretically.

Hedgehog pathway dysregulation contributes to the pathogenesis of human gastrointestinal stromal tumors via GLI-mediated activation of KIT expression. [PDF]

open access: yes, 2016
Gastrointestinal stromal tumors (GIST) arise within the interstitial cell of Cajal (ICC) lineage due to activating KIT/PDGFRA mutations. Both ICC and GIST possess primary cilia (PC), which coordinate PDGFRA and Hedgehog signaling, regulators of ...

Path-integral Monte Carlo simulations for interacting few-electron quantum dots with spin-orbit coupling [PDF]

open access: yes, 2005
We develop path-integral Monte Carlo simulations for a parabolic two-dimensional (2D) quantum dot containing $N$ interacting electrons in the presence of Dresselhaus and/or Rashba spin-orbit couplings.
