Not All Agreements Are Equal: Heterogeneous Effects of RTAs on Latin American Agri‐Food Exports, 1990–2019

open access: yesAgribusiness, EarlyView.
ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

From Swarm to Individual: Emergent Individuality in Light‐Mediated Robot Collectives

open access: yesAdvanced Intelligent Systems, EarlyView.
Can individuality emerge from a swarm? Using nominally homogeneous phototactic robots, we show that collective light conditions reorganize robot‐level behavioral profiles. Global illumination amplifies persistent differences in state occupancy, while robot‐mounted local light cues reduce fixed differentiation and favor transient high‐switching profiles.

UBE3A Dosage Imbalance as a Molecular Framework Linking Angelman Syndrome and Dup15q‐Associated Autism Phenotypes

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT UBE3A is a dosage‐sensitive HECT E3 ubiquitin ligase whose neuronal expression is shaped by genomic imprinting at the 15q11.2‐q13 locus. Opposite directions of UBE3A dosage imbalance contribute to distinct neurodevelopmental phenotypes: loss of maternal UBE3A underlies Angelman syndrome, whereas maternally derived 15q11.2‐q13 copy‐number gains,

Anatomical and histochemical bark changes due to growth of Tillandsia recurvata (ball moss)

open access: yesBotan‪ical Sciences, 2016
Excessive growth of Tillandsia recurvata (ball moss) may impact host architecture and survival. For a better understanding of this effect, an anatomical and histochemical bark assessment was carried out in four host species.

Case‐malformed signal detection and prioritisation using EUROmediCAT data for pharmacovigilance in pregnancy

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Many women take medications during pregnancy. However, the risk to the fetus from most medications is uncertain. Congenital anomalies are one of the leading causes of infant death and contribute to long‐term disability. Signal detection methods can be used to systematically identify possible medication–anomaly associations that require further ...

Survival strategies of plants during secondary growth: barrier properties of phellems and lenticels towards water, oxygen, and carbon dioxide [PDF]

open access: yesJournal of Experimental Botany, 2006
Ever since plants began to conquer the terrestrial environment, a simple but effective evolutionary strategy has been employed to cope with the combined necessities of preventing an excessive loss of water via the aerial surface while also supporting the vital exchange of CO(2) and O(2) for photosynthesis and respiration.

Young children's right to be heard on the quality of their education: Addressing potential misunderstandings in the context of early childhood education

open access: yesBritish Educational Research Journal, EarlyView.
Abstract In early childhood education many researchers and professionals across the world have embraced the United Nations Convention on the Rights of the Child's requirement to include young children in decision‐making. In the context of ongoing discussion about young children's capacity to share their views and opinions about matters affecting them ...

Molecular cloning and functional identification of sterol C24-methyltransferase gene from Tripterygium wilfordii

open access: yesActa Pharmaceutica Sinica B, 2017
Sterol C24-methyltransferase (SMT) plays multiple important roles in plant growth and development. SMT1, which belongs to the family of transferases and transforms cycloartenol into 24-methylene cycloartenol, is involved in the biosynthesis of 24-methyl ...
