Joint attention in the first year: The coordination of gaze and affect between 7 and 10 months of age [PDF]

open access: yes, 2005
We used a multilevel growth model to describe the developmental trajectories of infant’s coordinated attention between people and objects between 7 and 10 months of age.

Engineering of an Ancestral McbA with Enhanced Domain Mobility Extends Biocatalytic Amide Synthesis Scope

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
We show how engineered ancestral amide bond synthetases (ABSs) together with cofactor recycling using a single polyphosphate kinase paves the way for chemoenzymatic synthesis of pharmacophores. The figure illustrates how ancestral ABS has a more flexible C‐terminal domain, which is associated with enhanced catalytic performance and expanded amine scope.

The role of emotion-related individual differences in enjoyment and masking smile judgment

open access: yesBMC Psychology, 2023
Background While some research indicates that individuals can accurately judge smile authenticity of enjoyment and masking smile expressions, other research suggest modest judgment rates of masking smiles.

Facial Mimicry of Spontaneous and Deliberate Duchenne and Non-Duchenne Smiles [PDF]

open access: yes, 2014
Increasing evidence suggests that Duchenne (D) smiles may not only occur as a sign of spontaneous enjoyment, but can also be deliberately posed. The aim of this paper was to investigate whether people mimic spontaneous and deliberate D and non-D smiles ...

A novel methodology on distributed representations of proteins using their interacting ligands

open access: yes, 2018
The effective representation of proteins is a crucial task that directly affects the performance of many bioinformatics problems. Related proteins usually bind to similar ligands.

Deep Learning Approach for Predicting Efficiency in Organic Photovoltaics from 2D Molecular Images of D/A Pairs

open access: yesAdvanced Theory and Simulations, EarlyView.
This study highlights the potential of deep learning, particularly Convolutional Neural Networks (CNNs), for predicting the photovoltaic performance of organic solar cells. By leveraging 2D images representing donor/acceptor molecular pairs, the model accurately estimates key performance indicators proving that this image‐based approach offers a fast ...

Phylogeny and ontogeny of spontaneous smiles

open access: yesJournal of Human Environmental Studies, 2009
Spontaneous smiles are the first smiles which infants show, and they occur during irregular sleep or drowsiness. In the 1960s, some researchers conducted observations on full-term and preterm neonates, and recorded spontaneous smiles. But little is known

VDLIN: A Deep Learning‐Based Platform for Methylcobalamin‐Inspired Immunomodulatory Compound Screening

open access: yesAdvanced Science, EarlyView.
Using the convolutional neural network model VDLIN, Co7 is identified as a promising therapeutic candidate. Co7 demonstrates distinct advantages over MCB by effectively balancing anti‐inflammatory and immune‐stimulatory functions, making it a potential novel approach for immune modulation.

Temporal dynamics of pain smile [PDF]

open access: yes, 2012
In temporal dynamics of facial expressions it has been suggested that fake and genuine expressions may be distinguished mostly through differences in their temporal pattern.

Polyhalogenated Carbazole Impairs Dopaminergic Neurons through Dysregulation of Liquid–Liquid Phase Separation in Caenorhabditis elegans

open access: yesAdvanced Science, EarlyView.
Polyhalogenated carbazoles (PHCZ), persistent environmental contaminants, preferentially accumulate in neuronal tissues. Studies using Caenorhabditis elegans and human neuronal cell lines reveal that PHCZ induce dopaminergic neurodegeneration by promoting liquid–liquid phase separation of α‐synuclein, reducing condensate fluidity, impairing ...
