Concurrent Empirical Magnetic Reconstruction of Storm and Substorm Spatial Scales Using Data Mining and Virtual Spacecraft

open access: yesFrontiers in Physics, 2021
Data mining (DM) has ushered in a new era of empirical magnetic reconstructions of the magnetosphere via application of the k-nearest neighbors (kNN) method.

Circulating and persistent currents induced by a current magnification and Aharonov-Casher phase [PDF]

open access: yes, 1998
We considered the circulating current induced by the current magnification and the persistent current induced by Aharonov-Casher flux. The persistent currents have directional dependence on the direct current flow, but the circulating currents have no ...

Parity Effect in a mesoscopic superconducting ring

open access: yes, 2000
We study a mesoscopic superconducting ring threaded by a magnetic flux when the single particle level spacing is not negligible. It is shown that, for a superconducting ring with even parity, the behavior of persistent current is equivalent to what is ...

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Improved Lifetime Model of Energetic Electrons Due to Their Interactions With Chorus Waves

open access: yesGeophysical Research Letters
Chorus waves induce both electron acceleration and loss. In this letter, we provide significantly improved models of electron lifetime due to interactions with chorus waves.

Persistent Currents of Single Mesoscopic Rings [PDF]

open access: yesEurophysics Letters (EPL), 1992
We study the stochastic fluctuations (from sample to sample) in the persistent current I() of mesoscopic rings threaded by a flux . We find that it is necessary to include the Coulomb interaction between the electrons. Then we obtain I21/2 ~ (L/l)I ~ evF/L; and h/e for the dominant period in .

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

SIMULATION STUDY OF THE ENERGETIC NEUTRAL ATOM (ENA) IMAGING MONITORING OF THE GEOMAGNETOSPHERE ON A LUNAR BASE

open access: yesSolar-Terrestrial Physics, 2021
Since the moon’s revolution cycle is exactly the same as its rotation cycle, we can only see the moon always facing Earth in the same direction. Based on the clean particle radiation environment of the moon, a neutral atomic telemetry base station could ...

Mono-parametric quantum charge pumping: interplay between spatial interference and photon-assisted tunneling

open access: yes, 2005
We analyze quantum charge pumping in an open ring with a dot embedded in one of its arms. We show that cyclic driving of the dot levels by a \textit{single} parameter leads to a pumped current when a static magnetic flux is simultaneously applied to the ...

Parent‐to‐Child Information Disclosure in Pediatric Oncology

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...
