Long-memory Gaussian processes governed by generalized Fokker-Planck equations

open access: yes, 2019
It is well-known that the transition function of the Ornstein-Uhlenbeck process solves the Fokker-Planck equation. This standard setting has been recently generalized in different directions, for example, by considering the so-called $\alpha $-stable ...

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts

open access: yesAdvanced Science, EarlyView.
We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.

Приложение дробной модели деформационной активности к исследованию свойств эредитарности и нестационарности сейсмического процесса в зоне субдукции Курило-Камчатской островной дуги в фазе релаксации

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Исследование свойств эредитарности и нестационарности сейсмического процесса в фазе релаксации проводится на основании данных каталога землетрясений КФ ЕГС РАН (01.01.1962 − 31.12.2002, зона субдукции Курило-Камчатской островной дуги).

General Fractional Calculus, Evolution Equations, and Renewal Processes

open access: yes, 2011
We develop a kind of fractional calculus and theory of relaxation and diffusion equations associated with operators in the time variable, of the form $(Du)(t)=\frac{d}{dt}\int\limits_0^tk(t-\tau)u(\tau)\,d\tau -k(t)u(0)$ where $k$ is a nonnegative ...

Rapid Remodeling of the Human Gut Microbiome in Response to Short‐Term Animal Product Restriction and Associations with Host Molecular Phenotypes

open access: yesAdvanced Science, EarlyView.
A real‐world model of structured animal product restriction practiced for religious reasons reveals the dynamic adaptability of the human gut microbiome to dietary change and uncovers reductions in diversity and rare taxa loss. Integrated microbiome, metabolomic, and proteomic analyses uncover coordinated taxonomic and molecular shifts and identify ...

Предвестники землетрясений в теории критичности геодеформаций

open access: yesVestnik KRAUNC: Fiziko-Matematičeskie Nauki
Предвестники землетрясений рассматриваются как резонансные проявления критических геодеформаций, дислокационные изменения которых отвечают за аномальные свойства, как самих деформаций, так и порожденных ими физических процессов, играющих роль индикаторов

PET Imaging of Cardiac Inflammation in Viral Myocarditis Using a DPP4‐Targeted Probe

open access: yesAdvanced Science, EarlyView.
This study describes a DPP4‐targeted PET probe for imaging myocardial inflammation by selectively targeting activated immune cells. Derived from the clinically approved small‐molecule inhibitor linagliptin, the probe demonstrates favorable biodistribution with specific cardiac uptake in myocarditis.

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

PEMFC Improved Fractional-order Subspace Identification Model Based on IECSDE Algorithm [PDF]

open access: yesJisuanji gongcheng
To accurately describe the characteristics of a Proton Exchange Membrane Fuel Cell (PEMFC) during its power-generation process and the relationship among variable effects, an improved fractional-order subspace identification method based on the ...
