Representation of Sickle Cell Disease Patients in Pediatric and Adult Care: What We Discovered Using Informatics for Integrating Biology and the Bedside (i2b2) Data

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Transitioning from pediatric to adult care is a high‐risk period for individuals with sickle cell disease (SCD). An initial observation at one academic medical center suggested a sex‐based disparity in clinic populations, prompting a national investigation.

Relative Velocity in Relativity Theory [PDF]

open access: yesNature, 1965
IT is questionable whether the Lorentz transformations should be applied to any of the experiments under discussion, since accelerations are involved. If they are, S, S′ and S″ in D. W. Posener's letter must be regarded as inertial systems and S′ is then moving with the velocity 2v relative to S″.

The jump and stagnation of mass with speed

open access: yesIET Quantum Communication, 2022
In the general theory of relativity, the four‐dimensional space‐time of describing a mass body accelerated motion or in a gravitational field, although it is a curved Riemannian geometric space from the perspective of “integral geometry”, but for any ...

Relativity without tears [PDF]

open access: yes, 2008
Special relativity is no longer a new revolutionary theory but a firmly established cornerstone of modern physics. The teaching of special relativity, however, still follows its presentation as it unfolded historically, trying to convince the audience of

Uncovering Inequities: The Role of Social Determinants of Health in Hospitalized Adolescents and Young Adults With Heavy Menstrual Bleeding

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Heavy menstrual bleeding (HMB) is a common condition among adolescents and young adults (AYAs) and is the leading cause of iron deficiency anemia (IDA) in this population. Growing evidence suggests that social determinants of health (SDOH) influence menstrual bleeding patterns, access to care, and treatment. However, no studies have

The origin of the spacetime metric: Bell's `Lorentzian pedagogy' and its significance in general relativity [PDF]

open access: yes, 1999
The purpose of this paper is to evaluate the `Lorentzian Pedagogy' defended by J.S. Bell in his essay ``How to teach special relativity'', and to explore its consistency with Einstein's thinking from 1905 to 1952.

Effectiveness of Resistance Intradialytic Exercise Compared to Aerobic Intradialytic Exercise for Patients With Chronic Kidney Disease: A Randomized Controlled Clinical Trial

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.

A Lorentz variant theory that passes fundamental tests of special relativity and makes diverging, testable but as of yet untested predictions [version 2; peer review: 2 approved]

open access: yesF1000Research
Background Tests of special relativity have been conducted over the past century with increasing accuracy and none have showed violations of Lorentz invariance.

Relative morsification theory

open access: yesTopology, 2004
In this paper we develope a Morsification Theory for holomorphic functions defining a singularity of finite codimension with respect to an ideal, which recovers most previously known Morsification results for non-isolated singulatities and generalize them to a much wider context.

On the Empirical Equivalence Between Special Relativity and Lorentz's Ether Theory [PDF]

open access: yes, 2013
In this paper I argue that the case of Einstein’s special relativity vs. Hendrik Lorentz’s ether theory can be decided in terms of empirical evidence, in spite of the predictive equivalence between the theories.
