Tecnologias envelhecidas? [PDF]

, 2017
Não há dúvida que, em tempos de novidades tecnológicas a cada semana ou a cada dia, o fascínio pelo novo e a fuga do que já está ultrapassado nos trazem a percepção de que tecnologias se tomam velhas com muita rapidez.

Species with U‐shaped geographic ranges as an opportunity to study early stages of divergence: The case of Ipomoea microsepala

American Journal of Botany, EarlyView.
Abstract Premise The study of the early stages of divergence between populations is crucial to understanding how species and biodiversity originate. Geographic distributions that capture some aspects of the process of divergence, such as those that are markedly U‐shaped, could offer a window to identify systems undergoing incipient speciation, which ...

The intensity and spatial dispersion of within‐plant herbivory drive trait‐specific resistance and tolerance in wild cotton

American Journal of Botany, EarlyView.
Abstract Premise Herbivory induces complex plant defensive responses that may vary depending on the amount and spatial dispersion of damage on the plant; however, of the two variables, damage dispersion has received much less attention. To address this gap, we studied wild cotton (Gossypium hirsutum) defensive responses to different herbivory amounts ...

Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

Angewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

First Report of Uniparental Isodisomy of Chromosome 15 Revealing Angelman Syndrome and Microphthalmia Associated With a Novel Homozygous ALDH1A3 Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Paternal isodisomy of chromosome 15 (iUPD15) is a recognized cause of Angelman syndrome (AS), accounting for approximately 2%–5% of cases. Additionally, another recognized consequence of iUPD is the unmasking of autosomal recessive disorders. However, reports of recessive disorders resulting from iUPD15 remain scarce in the literature.

From Atoms to Reactors: A Critical Review of a Decade of Machine Learning in Heterogeneous Catalysis (2017–2026)

Angewandte Chemie, EarlyView.
Machine learning has digitalized heterogeneous catalysis from the top of the length scale downward: prediction at the atom and the material is now mature, yet the reactor and the process remain the open frontier. This critical review traces a decade of progress across the full catalytic value chain and asks where the next decade of impact must be won ...

A Novel Homozygous Nonsense Variant in DCHS1 in a Brazilian Patient With Van Maldergem Syndrome Type 1: Clinical Report and Literature Review

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Van Maldergem syndrome (VMLDS) is an ultra‐rare autosomal recessive disorder characterized by craniofacial dysmorphism, intellectual disability, hypotonia, skeletal anomalies, and feeding difficulties. It is caused by biallelic variants in DCHS1 or FAT4 genes.

Template‐Encoded Assembly and Adaptive Function in Selenium‐Based Molybdenum Chalcoxide Rings

Angewandte Chemie, EarlyView.
External templates write structural information into Se‐containing molybdenum rings, while selenium's softness confers adaptive host–guest behaviour and catalytic responsiveness, an integrated framework for programmable inorganic function. ABSTRACT Controlling both structure and function in inorganic self‐assembly remains a major challenge.
