Advanced Science, EarlyView.Integrating experimental insights with molecular dynamics simulations, we establish an advanced mathematical model for fluids confined in sub‐10‐nm channels, enabling quantitative prediction of interfacial layer thickness and viscosity by accounting for channel material, temperature, and fluid properties.

Advanced Science, EarlyView.This study presents an injectable DNA‐based porous hydrogel integrating catechol motifs and targeting aptamers for pulpitis management. Upon in situ crosslinking, the scaffold actively recruits endogenous dental pulp stem cells, restores redox homeostasis, and modulates immune responses.

Advanced Science, EarlyView.To overcome severe signal oscillation under extreme impact conditions, this work presents a Sensing‐in‐Energy microdevice which integrates a MEMS inertial structure directly within a supercapacitor electrolyte cavity. Utilizing shock‐driven transient contact and electrolyte damping for signal self‐filtering, it achieves weak‐oscillation, large ...

Location of low-frequency oscillation sources using improved D-S evidence theory [PDF]
International Journal of Electrical Power and Energy Systems, 2021 This paper presents a method for localizing oscillation sources based on data fusion Dempster–Shafer (D-S) evidence theory. This study is based on data of each bus from the system collected by phasor measurement units (PMUs). Then the D-S evidence theory

Relative oscillation theory for Sturm–Liouville operators extended
Journal of Functional Analysis, 2008 We extend relative oscillation theory to the case of Sturm–Liouville operators Hu = r −1 (−(pu ′ ) ′ + qu) with different p’s. We show that the weighted number of zeros of Wronskians of certain solutions equals the value of Krein’s spectral shift ...

A theory of generalized Bloch oscillations
Journal of Physics: Condensed Matter, 2016Bloch oscillations of electrons are shown to occur for cases when the energy spectrum does not consist of the traditional evenly-spaced ladders and the potential gradient does not result from an external electric field. A theory of such generalized Bloch oscillations is presented and an exact calculation is given to confirm this phenomenon. Our results

Theory of Mitotic Spindle Oscillations
Physical Review Letters, 2005During unequal cell division the mitotic spindle is positioned away from the center of the cell before cell cleavage. In many biological systems this repositioning is accompanied by oscillatory movements of the spindle. We present a theoretical description for mitotic spindle oscillations.

AbstractIn the first section of this paper we extend an interesting result due to Nehari and develop some related ideas. The remainder of the paper has principally to do with sufficient conditions for oscillation of solutions of differential equations of the form y'' + p(x) y = 0, where p(x) is at least piecewise continuous on I: (a, ∞) and changes ...

The author uses a version of Gårding's inequality to obtain a (nodally oscillatory) comparison theorem which can then be used to extend his earlier non-oscillation theorems [the author, Math. Nachr. 141, 289- 297 (1989; Zbl 0682.35008)] to the equation \[ \sum_{|\alpha|,|\beta|=0}^ m(- 1)^{|\alpha|}D^ \alpha [A_{\alpha\beta}(x)D^ \beta u]=0, \] where \(
