Exploring Ligand Effects in the Selective Catalytic Dehydrogenative Borylation of Alkynes with Aluminum

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Proper selection of a modified guanidinato ligand allows for the selective catalytic dehydroborylation of terminal alkynes by an air‐stable aluminum complex. A plausible reaction pathway is suggested based on DFT studies, where the auxiliary substituent of the guanidinato ligand actively participates in the activation of the σ CH bond.

Face Gender Influences the Looking Preference for Smiling Expressions in 3.5-Month-Old Human Infants.

open access: yesPLoS ONE, 2015
Young infants are typically thought to prefer looking at smiling expressions. Although some accounts suggest that the preference is automatic and universal, we hypothesized that it is not rigid and may be influenced by other face dimensions, most notably

Wearing Many (Social) Hats: How Different are Your Different Social Network Personae?

open access: yes, 2017
This paper investigates when users create profiles in different social networks, whether they are redundant expressions of the same persona, or they are adapted to each platform.

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.

Relationships of Smiling and Flirtation to Aggression and 2D:4D, a Prenatal Androgen Index

open access: yesEvolutionary Psychology, 2011
Smiling has been reported to be a signal of submission/lower status, or a sign of cooperation. In the present study, use of smiling and flirtation to “make people receptive to my ideas” was conceptualized as mild aggression, since it is mildly ...

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 ...

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.
