In this paper we present the techniques used for University of Montréal's team submissions to 2013 Emotion Recognition in Wild Challenge. The challenge is classify emotions expressed by primary human subject short video clips extracted from feature length movies. This involves analysis acted scenes lasting approximately one-two seconds, including audio track which may contain voices as well background music. Our approach combines multiple deep neural networks different data modalities,...
As demands on Li-ion battery performance increase, the need for electrolytes with high ionic conductivity and a Li+ transference number (tLi) becomes crucial to boost power density. Unfortunately, tLi in liquid is typically <0.5 due migrating via vehicular mechanism, whereby diffuses along its solvation shell, making diffusivity slower than counteranion. Designing where ion independently of shell significant interest enhance number. In this work, we elucidate how properties solvent influence...
Enhancing the power of lithium-ion batteries necessitates understanding molecular processes governing Li+ ion transfer across electrode-electrolyte interface. Here, employing enhanced sampling dynamics simulations, we investigated driving force and thermodynamic barrier adsorption onto Li0.5CoO2 (104) in LiClO4-, LiPF6-, LiTFSI-based EC/EMC (3:7) electrolytes. The weaker cation-anion pairing LiTFSI compared to LiClO4 was found enhance for from -0.48 eV -1.26 an interface with zero cation...
Charge transport in deoxyribonucleic acid (DNA) is of immense interest biology and molecular electronics. Electronic coupling between the DNA bases an important parameter describing efficiency charge DNA. A reasonable estimation this electronic requires many expensive first principle calculations.

In this minireview, we discuss important aspects of the various quantum phenomena (such as interference, spin-dependent charge transport, and thermoelectric effects) relevant in single-molecule transport list some basic circuit rules devised for different molecular systems. These phenomena, conjunction with existing empirical rules, can help predicting structure–property relationships circuits. However, a universal law that predicts properties has not been derived yet. Having such law(s)...

The crucial role of electrolyte cations in CO2 electroreduction has received intensive attention. One prevailing theory is that through electrostatic interactions or direct coordination, larger such as Cs+ can better stabilize the key intermediate species for CO and multicarbon (C2+) product generation, example, on silver copper, respectively. Herein, we show smaller, more acidic alkali metal greatly enhance CO2-to-methanol conversion kinetics (Li+ > Na+ K+ Cs+) an immobilized molecular...

Double-stranded DNA (dsDNA) has been established as an efficient medium for charge migration, bringing it to the forefront of field molecular electronics and biological research. The migration rate is controlled by electronic couplings between two nucleobases DNA/RNA. These strongly depend on intermolecular geometry orientation. Estimating these all possible relative geometries molecules using computationally demanding first-principles calculations requires a lot time computational...
