The difference in accommodative amplitude and facility between the dominant and non-dominant eyes
Journal of the Pakistan Medical AssociationThe cross-sectional study was planned to compare the amplitude of accommodation and accommodative facility between the dominant and non-dominant eyes in young university students.

Journal of Nobel Medical College, 2018 Background: The unique ability of the eye to vary the refractive power of the lens and to focus on things at a range of distances is called accommodation. The reduction of this ability in which the near point recedes further away from comfortable reading

Jump in fluid properties of inflationary universe to reconcile scalar and tensor spectra [PDF]
Phys. Rev. D 90, 063525 (2014), 2014 The recent detection of the primordial gravitational waves from the BICEP2 observation seems to be in tension with the upper bound on the amplitude of tensor perturbations from the PLANCK data. We consider a phenomenological model of inflation in which the microscopical properties of the inflationary fluid such as the equation of state $w$ or the sound

Novel Improvement for Nonlinear Compatibility of Least Mean Square Adaptive Algorithm [PDF]
arXiv, 2022 In order to improve the least mean squares (LMS) adaptation algorithm to accommodate the nonlinear transfer function, and to adjust the coefficients of adaptive filter during the actual implement of bias voltage and signal amplitude, methods are proposed and simulated to develop a nonlinear adaptive filter.

Adversarial amplitude swap towards robust image classifiers [PDF]
arXiv, 2022 The vulnerability of convolutional neural networks (CNNs) to image perturbations such as common corruptions and adversarial perturbations has recently been investigated from the perspective of frequency. In this study, we investigate the effect of the amplitude and phase spectra of adversarial images on the robustness of CNN classifiers.

Holographic Scattering Amplitudes [PDF]
arXiv, 2017 Inspired by ancient astronomy, we propose a holographic description of perturbative scattering amplitudes, as integrals over a `celestial sphere'. Since Lorentz invariance, local interactions, and particle propagations all take place in a four-dimensional space-time, it is not trivial to accommodate them in a lower-dimensional `celestial sphere'.

New Physics in B-Bbar mixing in the light of recent LHCb data [PDF]
, 2012 We perform model-independent statistical analyses of three scenarios accommodating New Physics (NP) in Delta F=2 flavour-changing neutral current amplitudes. In a scenario in which NP in B_d-B_d-bar and B_s-B_s-bar is uncorrelated, we find the parameter point representing the Standard-Model disfavoured by 2.4 standard deviations.

Sparse Frequency Analysis with Sparse-Derivative Instantaneous Amplitude and Phase Functions [PDF]
arXiv, 2013 This paper addresses the problem of expressing a signal as a sum of frequency components (sinusoids) wherein each sinusoid may exhibit abrupt changes in its amplitude and/or phase. The Fourier transform of a narrow-band signal, with a discontinuous amplitude and/or phase function, exhibits spectral and temporal spreading.

Journal of Ophthalmology, 2020 Background: As there is close association between pupil response and accommodation during gaze fixation on an object at any distance, it is important to assess accommodative pupil response both in healthy children and in those with accommodative ...
