The Coulomb gauge has a long history and many uses. It is especially useful in bound state applications. An important feature of this gauge is that the matter fields have an infra-red finite propagator in an on-shell renormalisation scheme. This is, however, only the case if the renormalisation point is chosen to be the static point on the mass-shell, p = (m, 0, 0, 0). In this letter we show ho...

The infra red 3D mouse is a three dimensional input device to a computer. It works by determining the position of an arbitrary object (like a hand) by emitting infra red signals from a number of locations and measuring the reflected intensities. To maximize stability, robustness, and use of bandwidth, the signals are designed by means of the wavelet and the RudinShapiro transforms. This also al...

In this paper, the infra-red absorption spectra of a number of crystalline natural estrogens are presented and considered in relation to chemical structure. As a group, the natural estrogens are distinguished chemically from other steroids by the benzenoid structure of Ring A, which gives rise to certain infra-red absorption bands by which their spectra may be differentiated from those of other...

Despite many advances during the last decade in both infra-red sensor and solid state camera technology, until now little headway has been made in the production of cost-effective semiconductor sensor arrays capable of operating far into the infra-red. Old ideas, renewed by the capabilities offered by the latest micromachine technology, may change all this. Reviews the problems associated with ...

Precision gas mixing pumps produce CO(2) gas mixtures for the calibration of infra-red CO(2) gas analyzers equivalent in accuracy to the standard CO(2) gas mixtures (+/- 1%) supplied by the National Bureau of Standards, Washington, D. C.The calibration of infra-red gas analyzers by the pressure difference method and by concentration differences did not agree. A factor of 0.709 was necessary to ...

In the context of a recently proposed method for computing exactly string loop corrections regularized in the infra-red, we determine and calculate the universal moduli-dependent part of the threshold corrections to the gauge couplings for the symmetric Z 2 ×Z 2 orbifold model. We show that these corrections decrease the unification scale of the underlying effective field theory. We also commen...

Our previous human fMRI study found brain activations correlated with tactile stickiness perception using the uni-variate general linear model (GLM) (Yeon et al., 2017). Here, we conducted an in-depth investigation on neural correlates of sticky sensations by employing a multivoxel pattern analysis (MVPA) on the same dataset. In particular, we statistically compared multi-variate neural activit...

Inferior vena cava (IVC) anomalies were rare and usually asymptomatic. Among these, anomalies absence of infra-renal IVC is the rarest anomaly. Absence of infra-renal IVC may present with symptoms of venous insufficiency and idiopathic deep vein thrombosis. Contrast enhanced CT and MRI abdomen play crucial role in diagnosing these anomalies. These patients can be managed conservatively or by ve...
