The Ideological “Coherence” of the Brazilian Party System, 1990-2009 A Coerência Ideológica do Sistema Partidário Brasileiro, 1990-2009

Journal of Politics in Latin America, 2010
This paper contributes to the debate about the ideological coherence of the Brazilian party system. Using discriminant function analysis of 20 years of surveys of Brazilian legislators, we find that the party system now exhibits relatively little ...

Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Knowing Left From Right: Ideological Identification in Brazil, 2002-2006 Diferenciando a Esquerda da Direita: Identificação Ideológica no Brasil, 2002-2006

Journal of Politics in Latin America, 2010
Ideology, typically defined on a left-right spectrum, should provide a means of communication between elites and masses. After years of leftist party rule, have Brazilian voters internalized ideological divisions? Longitudinal surveys conducted from 2002

a0(980)−f0(980) mixing in χc1→π0f0(980)→π0π+π− and χc1→π0a0(980)→π0π0η

Physics Letters B, 2017
We study the isospin breaking in the reactions χc1→π0π+π− and χc1→π0π0η and its relation to the a0(980)−f0(980) mixing, which was measured by the BESIII Collaboration.

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...

Presidential Control of High Courts in Latin America: A Long-term View (1904-2006) Control presidencial de las cortes supremas en América Latina. Una mirada histórica (1904-2006)

Journal of Politics in Latin America, 2009
In many Latin American countries the executive branch manipulatesthe composition of the Supreme Court, and judicial independence hasremained elusive. Because high courts can exercise judicial review and influencelower courts, incoming presidents often ...

Demonstration of Yb-Doped Fiber Amplifier Operating near 980 nm with the Slope Efficiency Close to the Theoretical Limit

Photonics, 2022
In this paper, the scalability of slope efficiency of a Yb-doped fiber amplifier operating near 980 nm is studied with the core-pumping scheme. By means of numerical prediction, it is found that the theoretical limit of slope efficiency should be about ...

Chiral Phase Change Nanomaterials

Advanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Delegation, Presidential Regimes, and Latin American Regulatory Agencies Delegación, regimenes presidenciales y agencias reguladoras en América Latina

Journal of Politics in Latin America, 2010
During the 1990s, a large number of regulatory agencies were created or reformed in different sectors in Latin American countries. Almost all included political delegation mechanisms, intended as formal rules to enhance credible commitments to time ...

Dynamic Interfacial Chemistry of Choline Chloride as Electrolyte Additive for Stable Zn‐Iodine Batteries

Advanced Functional Materials, EarlyView.
Choline chloride (ChCl) additive enables dynamic interface engineering in Zn‐I2 batteries by forming hydrophobic polyiodide complexes and a Zn‐stabilizing Ch+‐rich layer under electric field modulation. This dual‐function strategy suppresses iodine hydrolysis and dendrite formation, while optimizing Zn2+ solvation and transport for high‐efficiency ...
