New advances in assessment of the individual renal function in chronic unilateral renal obstruction using functional CT compared to 99mTc-DTPA renal scan [PDF]

open access: yes, 2014
BACKGROUND: The selection of optimal treatment for obstructive nephrouropathy requires information about the functional status of each kidney. Nuclear renal scanning objectively measure differential renal function.

T‐Cell Remodeling in Renal Fibrosis: From Acute Injury to Chronic Kidney Disease

open access: yesAdvanced Science, EarlyView.
This Review presents renal fibrosis as a sequence of overlapping T‐cell programs, from chemokine‐guided recruitment and metabolic activation to maladaptive polarization, tertiary lymphoid structure formation, tissue residency, exhaustion, and senescence.

Variational and Numerical Analysis for an Electro-Viscoelastic Unilateral Contact Problem with Adhesion

open access: yesPan-American Journal of Mathematics
In this paper we investigate a mathematical model for the unilateral contact between an electro-viscoelastic body and a conductive foundation. The Signorini conditions are used to model the contact, and adhesion between the contact surfaces is also taken

Unilateral Contact of Elastic Bodies (Moment Theory) [PDF]

open access: yesgmj, 2001
Abstract Boundary contact problems of statics of the moment (couple-stress) theory of elasticity are studied in the case of a unilateral contact of two elastic anisotropic nonhomogeneous media. A problem, in which during deformation the contact zone lies within the boundaries of some domain, and a problem, in which the contact zone can ...

Evolution of Physical Intelligence Across Scales

open access: yesAdvanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

Mathematical Formulation of Soft-Contact Problems for Various Rheological Models of Damper

open access: yesShock and Vibration, 2018
The paper deals with analysis of selected soft-contact problems in discrete mechanical systems. Elastic-dissipative rheological schemes representing dampers as well as the notion of unilateral constraints were used in order to model interaction between ...

A Viscoelastic Contact Problem with Adhesion and Surface Memory Effects

open access: yesMathematical Modelling and Analysis, 2014
We consider a mathematical model which describes the quasistatic contact between a viscoelastic body and an obstacle, the so-called foundation. The material's behavior is modelled with a constitutive law with long memory.

Asymptotic expansions of vibrations with small unilateral contact [PDF]

open access: yes, 2009
We study some spring mass models for a structure having a small unilateral contact with a small parameter ε. We valid an asymptotic expansion with the method of strained coordinates with new tools to handle such defects, including a non negligible cumulative effect over a long time: $T_\varepsilon \sim \varepsilon^{-1}$ as usual; or, for a new critical

The Fragility of Estimated Effects of Unilateral Divorce Laws on Divorce Rates [PDF]

open access: yes
Following an influential article by Friedberg (1998), Wolfers (2006) explored the sensitivity of Friedberg’s results to allowing for dynamics in the response of divorce rates to the adoption of unilateral divorce laws.

Milestone Attainment in Young Children With Arthrogryposis Multiplex Congenita: Developmental Profile and Associated Factors

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView.
ABSTRACT Evidence on developmental milestones in children with arthrogryposis multiplex congenita (AMC) under the age of five is scarce. This multisite cross‐sectional study described developmental status and examined factors associated with milestone attainment in 143 children aged 0–66 months from a pediatric AMC Registry.
