On the dissipation layer of radial bearings

International Journal of Mathematics and Mathematical Sciences, 1988
The dissipation boundary layer of certain radial bearings is identified. It is shown that, under certain conditions, the temperature outside this layer is constant.

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

Mathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Periodontal Therapy–Related Changes in Clinical Parameters, Active‐Matrix Metalloproteinase‐8 and C‐Reactive Protein in Prediabetes and Diabetes

Oral Diseases, EarlyView.
ABSTRACT Objectives This study investigated the effect of nonsurgical periodontal therapy (NSPT) on periodontal clinical parameters, active‐matrix metalloproteinase‐8 (aMMP‐8), high sensitivity C‐reactive protein (hsCRP), and glycated hemoglobin (HbA1c), and their relationships in diabetes and prediabetes patients with periodontitis.

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

Plant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Plasmodium falciparum Parasites With Histidine‐Rich Protein 2 (pfhrp2) and pfhrp3 Gene Deletions in Frontier Endemic Regions of Brazilian Amazon

Tropical Medicine &International Health, EarlyView.
ABSTRACT Studies reporting deletions of the pfhrp2 and pfhrp3 genes in P. falciparum populations in various malaria‐endemic countries, including countries bordering Brazil, are increasing. Individuals infected with P. falciparum carrying deletions of the pfhrp2/3 genes may yield false‐negative results in Rapid Diagnostic Tests (RDTs) based on the ...

Ultrafast opto-magnetic effects in the extreme ultraviolet spectral range

Communications Physics
Coherent light-matter interactions mediated by opto-magnetic phenomena like the inverse Faraday effect (IFE) are expected to provide a non-thermal pathway for ultrafast manipulation of magnetism on timescales as short as the excitation pulse itself.

Towards a Trade War in 2025: Real Threats for the World Economy, False Promises for the US

The World Economy, EarlyView.
ABSTRACT Using the MIRAGE‐Power computable general equilibrium (CGE) model, we simulate a trade war initiated in 2025 by the new US administration. The central scenario consists in a 60‐percentage point tariff increase on all US imports from China, a 10‐percentage point tariff increase on all products from other partners, except Canada and Mexico, and ...

Comparison between free light chains and immunofixation electrophoresis: one-year data from a tertiary hospital

Türk Biyokimya Dergisi
Immunofixation electrophoresis (IFE) is a biochemical diagnostic method used in the diagnosis, treatment, and follow-up of monoclonal gammopathies. Paraproteinaemias involve overproduction of immunoglobulins, known as paraproteins or monoclonal proteins (
