Tension lines of the skin
(Springer, Cham, 2019-05-29)Skin tension lines are natural lines of tension that occur within the skin as a result of growth and remodeling mechanisms. Researchers have been aware of their existence and their surgical implications for over 150 years. ... -
Testing the validity of a mechanism describing the oxidation of binary n-heptane/toluene mixtures at engine operating conditions
(Elsevier, 2019-11-02)The aim of this work is to evaluate the influence of the n-heptane/toluene ratio on the reactivity of binary toluene reference fuels (TRFs), through a combined experimental and numerical work. Novel experimental ignition ... -
TeV and Multi-wavelength Observations of Mrk 421 in 2006-2008
(2011)We report on TeV gamma-ray observations of the blazar Mrk 421 (redshift of 0.031) with the VERITAS observatory and the Whipple 10m Cherenkov telescope. The excellent sensitivity of VERITAS allowed us to sample the TeV ... -
TeV Gamma-Ray Observations of the Perseus and Abell 2029 Galaxy Clusters
(2006)Galaxy clusters might be sources of TeV gamma rays emitted by high-energy protons and electrons accelerated by large scale structure formation shocks, galactic winds, or active galactic nuclei. Furthermore, gamma rays may ... -
Theoretical and kinetic study of the hydrogen atom abstraction reactions of esters with HO2 radicals
(American Chemical Society, 2013-10-31)This work details an ab initio and chemical kinetic study of the hydrogen atom abstraction reactions by the hydroperoxyl radical (HO2) on the following esters: methyl ethanoate, methyl propanoate, methyl butanoate, methyl ... -
Theoretical chemical kinetic study of the h-atom abstraction reactions from aldehydes and acids by Ḣ Atoms and ȮH, HȮ2, and ĊH3 radicals
(American Chemical Society, 2014-11-11)We have performed a systematic, theoretical chemical kinetic investigation of H atom abstraction by H atoms and OH, HO2, and CH3 radicals from aldehydes (methanal, ethanal, propanal, and isobutanal) and acids (methanoic ... -
Theoretical kinetics analysis for Ḣ atom addition to 1,3-Butadiene and related reactions on the Ċ4H7 potential energy surface
(American Chemical Society, 2017-09-08)The oxidation chemistry of the simplest conjugated hydrocarbon, 1,3-butadiene, can provide a first step in understanding the role of polyunsaturated hydrocarbons in combustion and, in particular, an understanding of their ... -
A theoretical study of cyclic ether formation reactions
(Elsevier, 2016-06-09)Cyclisation reactions of hydroperoxyl-alkyl radicals forming cyclic ethers and hydroxyl radicals play an important role in low temperature oxidation chemistry. These reactions contribute to the competition be-tween radical ... -
Theoretical study of the rate constants for the hydrogen atom abstraction reactions of esters with •OH radicals
(American Chemical Society, 2014-05-30)A systematic investigation of the rate constants for hydrogen atom abstraction reactions by hydroxyl radicals on esters has been performed. The geometry optimizations and frequency calculations were obtained using the ... -
A thermodynamic model of auto-regulated protein assembly by a supramolecular scaffold
(Wiley, 2019-03-12)Ligand-mediated regulation of protein assembly occurs frequently in different cellular contexts. Auto-regulated assembly, where a ligand acts as its own competitive inhibitor, provides a mechanism for exquisite control of ... -
Thermodynamics of linear and star polymers at fluid interfaces
(Royal Society of Chemistry, 2015)Performing molecular dynamics simulations on model systems we study the structural changes and thermodynamic stability of polymers of varying topology (linear and star-shaped) at interface between two liquids. We find that ... -
A theta-shaped amphiphilic cobaltabisdicarbollide anion: transition from monolayer vesicles to micelles
(Wiley, 2011-05-23)Self-assembly is ubiquitous in nature and in surfactant science.1 Globular micelles or vesicles in water are usually obtained with surfactants2 or amphiphilic block copolymers3 composed of a hydrophilic part and a hydrophobic ... -
Third and fourth-order elasticity of biological soft tissues
(Acoustical Society of America, 2010-01-24)In the theory of weakly nonlinear elasticity, Hamilton et al. [J. Acoust. Soc. Am. 116, 41-44 (2004)] identified W = -I2+(A/3)I3+DI22 as the fourth-order expansion of the strain-energy density for incompressible isotropic ... -
The third dimension of reading the sugar code by lectins: design of glycoclusters with cyclic scaffolds as tools with the aim to define correlations between spatial presentation and activity.
(MDPI, 2013-04-04)Coding of biological information is not confined to nucleic acids and proteins. Endowed with the highest level of structural versatility among biomolecules, the glycan chains of cellular glycoconjugates are well-suited to ... -
Third- and fourth-order constants of incompressible soft solids and the acousto-elastic effect.
(Acoustical Society of America, 2010-02)Acousto-elasticity is concerned with the propagation of small-amplitude waves in deformed solids. Results previously established for the incremental elastodynamics of exact non-linear elasticity are useful for the determination ... -
