Estabilización del sistema financiero alemán mediante la creación de la Banca Central, 1876-1914 [PDF]

open access: yesOla Financiera, 2014
Sin una armonización monetaria y la presencia de un banco central, el imperio Alemán, representa la experiencia más larga de un sistema de banca libre en los países industrializados de Europa en el Siglo XIX.

Diagnostic Efficacy of Digital Dermoscopy and Clinical Findings in Thin Melanoma of the Lower Limbs

open access: yesActa Dermato-Venereologica, 2017
The introduction of dermoscopy has improved the accuracy of diagnosis of melanoma. However, early stage melanoma can be difficult to diagnose. Eighty-nine cases of thin melanoma with a Breslow thickness ≤1 mm located on the lower limb and diagnosed ...

Breathers and Raman scattering in a two-leg ladder with staggered Dzialoshinskii-Moriya interaction

open access: yes, 2007
Recent experiments have revealed the role of staggered Dzialoshinskii-Moriya interaction in the magnetized phase of an antiferromagnetic spin 1/2 two-leg ladder compound under a uniform magnetic field.

Using stiffness to assess injury risk:comparison of methods for quantifying stiffness and their reliability in triathletes [PDF]

open access: yes, 2018
Background: A review of the literature has indicated that lower body stiffness, defined as the extent to which the lower extremity joints resists deformation upon contact with the ground, may be a useful measure for assessing Achilles injury risk in ...

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Correlations and confinement of excitations in an asymmetric Hubbard ladder

open access: yes, 2017
Correlation functions and low-energy excitations are investigated in the asymmetric two-leg ladder consisting of a Hubbard chain and a noninteracting tight-binding (Fermi) chain using the density matrix renormalization group method.

Enhanced Oxidation and Thermal Shock Resistance of N‐type Mg2Si0.89(Sn0.1,Sb0.01) Thermoelectric Material via Cr0.9Si0.1 Coating

open access: yesAdvanced Engineering Materials, EarlyView.
Cr0.9Si0.1 protective coatings are developed to enhance the thermal‐shock and oxidation resistance of Mg2Si0.89(Sn0.1,Sb0.01) thermoelectric (TE) materials. The coating forms a dense and adherent barrier that suppresses oxygen diffusion and mitigates mechanical degradation during cyclic oxidation, demonstrating its potential to improve the long‐term ...

Ground-state phases of rung-alternated spin-1/2 Heisenberg ladder

open access: yes, 2015
The ground-state phase diagram of Heisenberg spin-1/2 system on a two-leg ladder with rung alternation is studied by combining analytical approaches with numerical simulations.

3D Bioprinting of Thick Adipose Tissues with Integrated Vascular Hierarchies

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced 3D bioprinting technique is used here to create thick adipose tissues with a central, vessel and extensive branching. The construct is made using alginate, gelatin and collagen‐based bioinks. Flow through the complex vessel network is demonstrated as well as its successful integration with a femoral artery following implantation in a rat ...
