We investigate the formation of chains of few plasmonic nanoparticles - so called plasmonic oligomers - by strain induced fragmentation of linear particle assemblies. Detailed investigations of the fragmentation process are conducted by in-situ atomic force microscopy (AFM) and UV-vis-NIR spectroscopy. Based on these experimental results and mechanical simulations computed by the lattice spring model (LSM), we propose a formation mechanism which explains the observed decrease of chain polydispersity upon increasing strain and provides experimental guidelines for tailoring chain length distribution...

Mahbubur Rahman, Rovshan G Sadygov
Protein half-life is an important feature of protein homeostasis (proteostasis). The increasing number of in vivo and in vitro studies using high throughput proteomics provide estimates of the protein half-lives in tissues and cells. However, protein half-lives in cells and tissues are different. Due to the resource requirements for researching tissues, more data is available from cellular studies than tissues. We have designed a multivariate linear model for predicting protein half-life in tissue from its cellular properties...

Extreme climatic events affecting the Amazon region are expected to become more frequent under ongoing climate change. In this study, we assessed the responses to the 2010 drought of over 14,000 trees ≥ 10 cm dbh in a 25 ha lowland forest plot in the Colombian Amazon and how these responses varied among topographically defined habitats, with tree size, and with species wood density. Tree mortality was significantly higher during the 2010-2013 period immediately after the drought than in 2007-2010. The post-drought increase in mortality was stronger for trees located in valleys (+243%) than for those located on slopes (+67%) and ridges (+57%)...

The accurate understanding of the fate of volatile methylsiloxanes (VMS) in air is crucial in determining persistence and concentrations in the environment. Although oxidation by atmospheric hydroxyl radicals (oOH) is considered as a major degradation mechanism for airborne VMS, the existing bimolecular rate constants with •OH measured and modeled for any given VMS compound varied greatly, depending on the approaches used to generate the data. The objectives of this study were to measure •OH reaction rate constants for four cyclic and four linear VMS based on a relative rate method using a newly designed atmospheric chamber and to establish structure-reactivity relationships for the kinetics...

Epilepsy is a common neurological disorder characterized by recurrent, unprovoked seizures. The search for new treatments for seizures and epilepsy relies upon studies in animal models of epilepsy. To capture data on seizures, many applications require prolonged electroencephalography (EEG) with recordings that generate voluminous data. The desire for efficient evaluation of these recordings motivates the development of automated seizure detection algorithms. Approach: A new seizure detection method is proposed, based on multiple features and a simple thresholding technique...

One in five Latino men who have sex with men has experienced child sexual abuse. Although concerning in itself, child sexual abuse may increase an individuals' likelihood of depression and risk-taking in adult life, including engagement in HIV risk behaviors and alcohol and substance use. It is therefore urgent that researchers and practitioners better understand the long-term effects of child sexual abuse. We utilized logistic and linear regression to assess associations between child sexual abuse (operationalized as forced or coerced sexual activity before age 17) and depression, sexual behaviors, and drinking patterns in a sample of 176 adult Latino men who have sex with men from New York City...

We study the opening of double stranded DNA (dsDNA) in the presence of molecular crowders using the Peyrard-Bishop-Dauxois (PBD) model. It is a known fact that about 15-20% of the total volume of a cell is occupied by molecular crowders. The presence of crowders in the model is represented through the potential depth in the Morse potential. Using equilibrium statistical calculations we find the melting profile and the melting probabilities of the chain. We found that the melting temperature, Tm, increases in the presence of a crowder...

Georgios Fagogenis, Christos Bergeles, Pierre E Dupont
Concentric tube robots comprise telescopic precurved elastic tubes. The robot's tip and shape are controlled via relative tube motions, i.e. tube rotations and translations. Non-linear interactions between the tubes, e.g. friction and torsion, as well as uncertainty in the physical properties of the tubes themselves, e.g. the Young's modulus, curvature, or stiffness, hinder accurate kinematic modelling. In this paper, we present a machine-learning-based methodology for kinematic modelling of concentric tube robots and in situ model adaptation...
