Oscillation and nonoscillation of solutions to even order self-adjoint differential equations

Electronic Journal of Differential Equations, 2003
We establish oscillation and nonoscilation criteria for the linear differential equation $$ (-1)^nig(t^alpha y^{(n)}ig)^{(n)}- frac{gamma_{n,alpha}}{t^{2n-alpha}}y=q(t)y,quad alpha otin {1, 3, dots , 2n-1}, $$ where $$ gamma_{n,alpha}=frac{1}{4^n}prod_ ...

Quantitative Real‐Time MRI for the Assessment of Gastric Motility

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Current reference standards for measuring gastric emptying and motility are not considered optimal due to the time required, ionizing radiation, invasiveness, and spatial resolution. Purpose To assess gastric motility using novel real‐time dynamic magnetic resonance imaging in combination with static measurements for gastric ...

In vivo characterization of hippocampal electrophysiological processes in the heterozygous Pten knockout model of autism [PDF]

, 2018
While cognitive deficits have been described in the heterozygous Pten (+/-) KO mouse model of autism, little work has been done to demonstrate how corresponding in vitro physiological alterations in this model may underpin these cognitive deficits in ...

Stochastic Modelling of Daily Precipitation in Semi‐Arid Regions Using Markov Chains and Parametric Distributions

International Journal of Climatology, EarlyView.
This study applies stochastic rainfall models combining Markov Chains with gamma and mixed exponential distributions to a semi‐arid climate in Northeast Brazil. Model structures were evaluated using Bayesian Information Criterion (BIC), with maximum likelihood (MLM) for parameter estimation and cumulative distribution functions (CDFs) for validation ...

Medial parapatellar surgical approach leads to greater loss of postural sway complexity compared to mid‐vastus approach in women undergoing total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Total knee arthroplasty (TKA) is associated with acute postoperative effects that increase the risk of falls. These effects differ between the medial parapatellar (PP) and mid‐vastus (MV) surgical techniques but have not been evaluated in terms of postural sway complexity.

Enhanced Fear Memory in Adult Male C57BL/6 Mice Following Low‐Dose Isoflurane Exposure During Juvenile Development

Brain and Behavior
Objective To elucidate the neural mechanisms through which neonatal exposure to low‐dose anesthetic isoflurane (ISO) enhances adult fear memory, specifically examining neural oscillations and activation patterns in the mediodorsal thalamus (MDL), dentate

Entropic Leggett-Garg inequality in neutrinos and B (K) meson systems

, 2018
Entropic Leggett-Garg inequality is studied in systems like neutrinos in the context of two and three flavor neutrino oscillations and in neutral $B_d$, $B_s$ and $K$ mesons.
