Neutron scattering and extensive molecular dynamics simulations of an all atom C(100)H(202) system were performed to address the short-time dynamics leading to center-of-mass self-diffusion. The simulated dynamics are in excellent agreement with resolution resolved time-of-flight quasielastic neutron scattering. The anomalous subdiffusive center-of-mass motion could be modeled by explicitly acc...

After colorectal cancer (CRC) treatment, people reorganize life in ways that are consistent with their understanding of the illness and their expectations for recovery. Incapacities and abilities that have been lost can initiate a need to reorient the self. To the best of our knowledge, no studies have explicitly focused on the concept of self-reorientation after CRC treatment. The aim of the p...

Using the terahertz time-domain spectroscopy, we demonstrate the spin reorientation of a canted antiferromagnetic YFeO3 single crystal, by evaluating the temperature and magnetic field dependence of resonant frequency and amplitude for the quasi-ferromagnetic (FM) and quasi-antiferromagnetic modes (AFM), a deeper insight into the dynamics of spin reorientation in rare-earth orthoferrites is est...

Reorientational dynamics—motion defined by changes in the direction of a vector or tensor—determine relaxation behavior nuclear magnetic resonance (NMR). However, if multiple processes exist that result reorientation, then analyzing net effects becomes complex task, so one ideally would separate those motions to simplify analysis. The model-free and two-step approaches have established separabi...

We report on a thermodielectric bistability in dual frequency nematic liquid crystals (LCs) caused by the anisotropic nature of dielectric heating and director reorientation in an electric field. The bistability is a result of the positive feedback loop: director reorientation --> anisotropic dielectric heating --> dielectric anisotrophy --> director reorientation. We demonstrate both experimen...

Geometric features of surfaces and local information are constitutive elements of spatial representations. A number of studies in animals (rats) and human children (24 months old) have shown that in a rectangular environment with a reward hidden in one of the corners, geometric properties predominate over local cues for search strategies. In contrast, monkeys and human adults are able to take i...

Researchers have theorized that changing the way we think about our bodily responses can improve our physiological and cognitive reactions to stressful events. However, the underlying processes through which mental states improve downstream outcomes are not well understood. To this end, we examined whether reappraising stress-induced arousal could improve cardiovascular outcomes and decrease at...

This paper discusses the semantic theory presented in Robert Brandom’s Making It Explicit. I argue that it is best understood as a special version of dynamic semantics, so that these semantics by themselves offer an interesting theoretical alternative to more standard truth-conditional theories. This reorientation also has implications for more foundational issues. I argue that it gives us the ...

The symmetry-induced magnetic anisotropy due to monoatomic steps at strained Ni films is determined using results of first principles relativistic full-potential linearized augmented plane wave (FLAPW) calculations and an analogy with the Néel model. We show that there is a magnetoelastic anisotropy contribution to the uniaxial magnetic anisotropy energy in the vicinal plane of a stepped surfac...

When a navigator's internal sense of direction is disrupted, she must rely on external cues to regain her bearings, a process termed spatial reorientation. Extensive research has demonstrated that the geometric shape of the environment exerts powerful control over reorientation behavior, but the neural and cognitive mechanisms underlying this phenomenon are not well understood. Whereas some the...
