Estimation of anatomical dimensions of the thorax from computed tomography images of the adult and pediatric Indian population for developing optimal radiological protocols

Journal of Medical Physics, 2021
Purpose: Ionizing radiation has been extensively used for medical diagnosis since its discovery in 1895; however, excessive use can lead to deleterious effects.

Compact and extended objects from self-interacting phantom fields

, 2016
In this work we investigate localized and extended objects for gravitating, self-interacting phantom fields. The phantom fields come from two scalar fields with a "wrong sign" (negative) kinetic energy term in the Lagrangian.

Phantom Black Holes and Sigma Models

, 2011
We construct static multicenter solutions of phantom Einstein-Maxwell-dilaton theory from null geodesics of the target space, leading to regular black holes without spatial symmetry for certain discrete values of the dilaton coupling constant.

Evaluation of advective solute infiltration into porous media by pulsed focused ultrasound-induced acoustic streaming effects [PDF]

Ultrasonography
Purpose Acoustic streaming induced by applying transcranial focused ultrasound (FUS) promotes localized advective solute transport in the brain and has recently garnered research interest for drug delivery and enhancement of brain waste clearance.

Phantom hCG and Phantom Choriocarcinoma

Gynecologic Oncology, 1998
Phantom hCG and phantom choriocarcinoma syndrome (pseudohypergonadotropinemia) refers to persistent mild elevations of hCG, leading physicians to treat patients with cytotoxic chemotherapy for choriocarcinoma when in reality no true hCG or trophoblast disease is present. We report here three cases of the phantom hCG and phantom choriocarcinoma syndrome

Emergence in Re-emergent Indians: Para-history of The Re-Emergent Rankülche Indigenous People

Nuevo mundo - Mundos Nuevos, 2013
In this article I explore some blind points, lacunae and crevices that interrupt the sociohistorical process of the so-called reemergence of the Rankülche Indigenous People.

Transition between phantom and non-phantom phases with time dependent cosmological constant and Cardy-Verlinde formula

, 2011
We investigate the transition phenomenon of the universe between a phantom and a non-phantom phases. Particular attention is devoted to the case in which the cosmological constant depends on time and is proportional to the square of the Hubble parameter.

Exploring Green Fluorescent Protein Brownian Motion: Temperature and Concentration Dependencies Through Luminescence Thermometry

Advanced Physics Research
Luminescent nanothermometry emerges as a powerful tool for studying protein dynamics. This technique was employed to perform the first measurement of the temperature dependence of protein Brownian velocity, showcasing the illustrative example of enhanced

Activation rate uniformity in a bilateral IVNAA facility for two anthropomorphic phantoms [PDF]

Nuclear Technology and Radiation Protection, 2010
Activation rate uniformity is the first property which is considered in the design of a prompt γ-ray in vivo neutron activation analysis facility. Preliminary studies on the activation rate distribution in the body can be done by use of Monte Carlo ...

Cerebrospinal fluid micro-volume changes inside the spinal space affect intracranial pressure in different body positions of animals and phantom

Frontiers in Molecular Neuroscience, 2022
Interpersonal differences can be observed in the human cerebrospinal fluid pressure (CSFP) in the cranium in an upright body position, varying from positive to subatmospheric values. So far, these changes have been explained by the Monroe–Kellie doctrine
