Functional coatings deposited by an Atmospheric Pressure Plasma Jet (APPJ) system over Thermoplastic Elastomer (TPE) substrates
… in these areas, like thermoplastic elastomers (TPEs), involve a high degree of friction. So, in order to decrease the friction coefficient of the TPE, companies are using techniques as flocking. However, its high energy consumption, irregular distribution of fibers, poor adhesion and …

Two-photon absorption and nonlinear polariton effects in organic crystals
<p>Two-photon excitation (TPE) and second harmonic generation (SHG) have been studied in phenanthrene crystals at low temperatures (2 to 6K) in order to investigate mechanisms of two-photon absorption (TPA), the relationship between TPE and SHG, and polariton effects. The transition studied is of …

An Imaging Approach to Examine Telomere Dynamics and Regulation of Gene Expression with Aging
… models such as the telomere position effect (TPE), which suggests reduced interference of the telomere with transcriptional activity of increasingly more distant genes. A modification of the TPE model, referred to as Telomere Position Effects over Long Distance (TPE-OLD), explains why some …

An Integrative Review of the Literature on Technology Transformation in Healthcare
… guided by the theory of punctuated equilibrium (TPE). TPE describes the process of transformation within organizations, markets, and groups. The theory explains transformation as a pattern of long periods of incremental change (equilibrium) punctuated by short periods of dramatic change …

Beyond the Born Approximation: A Precise Comparison of e+p and e-p Elastic Scattering in the CEBAF Large Acceptance Spectrometer (CLAS)
… (<em>Q</em>²)=5.6 GeV². The two photon exchange (TPE) effect is the leading candidate to explain this discrepancy. The theoretical estimates of the TPE effect are model dependent so precise measurement is required to resolve this problem. The TPE effect can be measured in a model independent way …

Structure-Property Relationships of Polyisobutylene-Block-Polyamide Thermoplastic Elastomers
<p>Thermoplastic elastomers (TPEs) are a class of polymer fit for a wide variety of applications due to their customizability. In the synthesis of these types of materials, an elastically-performing polymer, deemed the “soft block,” is combined with a stiffer “hard block” polymer, each of which can …

A study of the composition and function of telomeric chromatin in drosophila melanogaster.
… phenomenon known as Telomere Position Effect (TPE). TPE is a phenomenon whereby normally active genes become repressed and silenced if relocated near to telomeres, and is thought to be a property of the proteins that constitute telomeric heterochromatin. Genetic dissection was used to exploit …

A precision measurement of the e⁺p/e⁻p elastic scattering cross section ratio at the OLYMPUS experiment
… the contributions from hard two-photon exchange (TPE) to elastic electron-proton scattering in the radiative corrections applied to the Rosenbluth separation measurements. Calculations of the hard TPE contribution are highly model dependent, but the effect may be measured experimentally with a …

Thermoplastic electrode surface modifications for use as label-free electrochemical immunosensors
… specifically thermoplastic electrodes (TPEs) due to their electrochemical performance and durability while remaining inexpensive. TPEs have been used for a wide variety of applications, but their use as immunosensors has been limited due to difficulty with antibody immobilization. This …

Rare events and dynamics in non-equilibrium systems
… we study the transition path ensemble (TPE), the set of transition paths between meta-stable states of Ito diffusions. In the limit of vanishing diffusivity, the Freidlin-Wentzell action characterises the asymptotics of the path-probability distribution over the TPE. We develop spectral …

Interpersonal Communication Patterns in Traumatic Perinatal Experiences
… who endured traumatic perinatal experiences (TPE). TPE is an intense perinatal process that creates psychological and emotional disruption irrespective of the baby's outcome. Ten vaginally delivered women, ages 25-40 years gave retrospective accounts of their TPEs. Women ranged from 2 months …
