Exactly solving the Kitaev chain and generating Majorana-zero-modes out of noisy qubits

Scientific Reports, 2022
Majorana-zero-modes (MZMs) were predicted to exist as edge states of a physical system called the Kitaev chain. MZMs should host particles that are their own antiparticles and could be used as a basis for a qubit which is robust-to-noise.

Prediction of flooding in distillation columns using machine learning

Digital Chemical Engineering, 2023
This work presents a new data-driven approach for early detection of anomalies, namely flooding, in distillation columns. The main contribution of this approach is that it does not rely on direct pressure measurements of the flooded sections to detect ...

Several lines of antioxidant defense against oxidative stress: antioxidant enzymes, nanomaterials with multiple enzyme-mimicking activities, and low-molecular-weight antioxidants

Archives of Toxicology
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are well recognized for playing a dual role, since they can be either deleterious or beneficial to biological systems.

Jasmonate Signaling Pathway Modulates Plant Defense, Growth, and Their Trade-Offs

International Journal of Molecular Sciences, 2022
Lipid-derived jasmonates (JAs) play a crucial role in a variety of plant development and defense mechanisms. In recent years, significant progress has been made toward understanding the JA signaling pathway. In this review, we discuss JA biosynthesis, as

ALÉM DO RIO SÃO FRANCISCO: Análise Tecnológica das Indústrias Líticas do Sítio Praça de Piragiba, Brasil

Clio Arqueológica, 2017
Neste trabalho, demonstramos o potencial da análise tecnológica que, junto com observações tafonômicas e o conhecimento da arqueologia regional, permitiu avaliar a homogeneidade da coleção lítica do Sítio Praça de Piragiba (Bahia).
