A note on the connectivity of 2-polymatroid minors [PDF]

arXiv, 2019
Brylawski and Seymour independently proved that if $M$ is a connected matroid with a connected minor $N$, and $e \in E(M) - E(N)$, then $M \backslash e$ or $M / e$ is connected having $N$ as a minor. This paper proves an analogous but somewhat weaker result for $2$-polymatroids.

Vitamin B12 Levels Association with Functional and Structural Biomarkers of Central Nervous System Injury in Older Adults

Annals of Neurology, EarlyView.
At low levels of B12, specifically when bound to transcobalamin for cellular uptake, evidence of slower conductivity in the brain could point toward impaired myelin. At high levels of B12, specifically when bound to the biologically inert transport protein haptocorrin, biomarkers of neurodegeneration appear in the serum, indicating neuroaxonal injury ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

Hepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Price of Anarchy with Heterogeneous Latency Functions [PDF]

arXiv, 2014
In this paper we consider the price of anarchy (PoA) in multi-commodity flows where the latency or delay function on an edge has a heterogeneous dependency on the flow commodities, i.e. when the delay on each link is dependent on the flow of individual commodities, rather than on the aggregate flow.

Neuropathological Evidence of Reduced Amyloid Beta and Neurofibrillary Tangles in Multiple Sclerosis Cortex

Annals of Neurology, EarlyView.
Multiple sclerosis (MS) and Alzheimer's disease are neurodegenerative diseases with age‐related disability accumulation. In MS, inflammation spans decades, whereas AD is characterized by Aβ plaques and neurofibrillary tangles (NFT). Few studies explore accumulation of amyloids in MS.

Association of the serum level of apolipoprotein E with coronary artery disease and carotid artery atherosclerosis in Kyrgyz men with dyslipidemia

Терапевтический архив, 2010
Aim: to study an association of the serum level of apolipoprotein E (apo-E) with risk factors for coronary heart disease (CHD), blood lipids and that with CHD and carotid artery (CA) atherosclerotic lesion in Kyrgyz men with dyslipidemia.

The polynomial property (V) [PDF]

arXiv, 2000
Given Banach spaces E and F, we denote by ${\mathcal P}(^k!E,F)$ the space of all k-homogeneous (continuous) polynomials from E into F, and by ${\mathcal P}_{wb}(^k!E,F)$ the subspace of polynomials which are weak-to-norm continuous on bounded sets. It is shown that if E has an unconditional finite dimensional expansion of the identity, the following ...

Impact of maternal high fat on neurovascular unit of adult offspring [PDF]

arXiv
Maternal obesity is associated with increased risk of diabetes, cardiovascular disease and hypertension in adult offspring. Midlife hypercholesterolemia and hypertension are risk factors for Alzheimer's disease, suggesting that the ageing brain may be impacted by early life environment.

Painleve's problem and the semiadditivity of analytic capacity [PDF]

arXiv, 2002
Let $\gamma(E)$ be the analytic capacity of a compact set $E$ and let $\gamma_+(E)$ be the capacity of $E$ originated by Cauchy transforms of positive measures. In this paper we prove that $\gamma(E)\approx\gamma_+(E)$ with estimates independent of $E$.
