Protonation‐Induced Electron Density Redistribution Facilitates Aggregation in PNNP Dicopper Hydride Complexes

Chemistry – A European Journal, EarlyView.
Copper(I) hydride complexes often exhibit diverse aggregation behavior that can profoundly influence their structure and reactivity. In this study we use a combined experimental and computational approach to identify key structural an electronic factors that govern aggregation in PNNP dicopperhydride complexes.

Multiple Dimerization Modes in Thiocarboxylate Paddlewheel Complexes: A Comprehensive View of Energy Landscapes from DFT Calculations and Statistics

Chemistry – A European Journal, EarlyView.
Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...

Prediction of stem attributes by combining airborne laser scanning and measurements from harvesters

Silva Fennica, 2012
In this study, a new method was validated for the first time that predicts stem attributes for a forest area without any manual measurements of tree stems by combining harvester measurements and Airborne Laser Scanning (ALS) data.

Fetal Pain Perception: Legislative Assertions and Developmental Neuroscience

Annals of the Child Neurology Society, EarlyView.
ABSTRACT Background Pain perception is a conscious experience, but neither pain nor consciousness is defined in the developing human fetus. Emergent consciousness may be regarded as a phenomenon that ultimately arises from an essential minimum of functional neuronal connectivity. Proposed U.S.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.
