Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

The approximate solution of Wiener-Hopf integral equations

Journal of Mathematical Analysis and Applications, 1972
AbstractThis paper develops an explicit approximate method of solving the integral equation (∗) f(x) = ∫0∞ h1(x − t)f(t) dt + g(x), x > 0, where g(x), h1(x) ϵ L1(R) ∩ L2(R),f(x) = g(x) = 0 if x < 0. The approximate solution depends upon 2 parameters, h > 0 and k ϵ (0, 1).

Tunable Applicator for Microneedle‐Based Medical Devices

Advanced Materials Technologies, EarlyView.
This paper presents a simple, low‐cost tunable applicator (TAPP) for microneedle array patches that uses a material‐agnostic controlled‐fracture mechanism to ensure reliable skin penetration and uniform array engagement. The scalable, modular design is compatible with injection molding and 3D printing, can be integrated directly into patches, and is ...

Functional Formulation of Quantum Theory of a Scalar Field in a Metric with Lorentzian and Euclidean Signatures

Entropy
We study the Schrödinger equation in quantum field theory (QFT) in its functional formulation. In this approach, quantum correlation functions can be expressed as classical expectation values over (complex) stochastic processes.

Impulsive Control Systems with Trajectories of Bounded p-Variation

Известия Иркутского государственного университета: Серия "Математика", 2017
The paper deals with impulse-trajectory relaxations of control-affine systems under the assumption that $L_1$-norms of the control functions are not uniformly bounded. Generalized solutions of such control systems may be of infinite total variation. Most

Temporal and Cell‐Specific Regulation of Synaptic Homeostasis by the Chromatin Remodeler Chd1

Advanced Science, EarlyView.
Chd1, the Drosophila homologue of mammalian CHD2 ‐ a gene linked to autism, epilepsy, and intellectual disability, is required for synaptic homeostatic plasticity. Chd1 in glia is necessary for the rapid induction of synaptic homeostasis, whereas Chd1 in motoneurons, muscle, and glia is critical for long‐term maintenance.

An indicator for Wiener-Hopf integral equations with invertible analytic symbol [PDF]

Integral Equations and Operator Theory, 1983
For Wiener-Hopf integral equations with an operator or matrix valued kernel and with an invertible symbol which is analytic on the real line and at infinity an indicator is introduced. In general this indicator is a bounded linear operator, but when the kernel is matrix valued and the symbol is rational it is a (possibly non-square) matrix.

Helix Alignment, Chevrons, and Edge Dislocations in Twist‐Bend Ferroelectric Nematics

Advanced Science, EarlyView.
The recently discovered twist‐bend ferroelectric nematic (NTBF) is the new member of the multiferroic family, representing a fluid with an oblique helicoidal (heliconical) periodic structure of spontaneous electric polarization. The work presents a thorough exploration of the material properties of this phase, how the periodic modulation of ...

Wiener–Hopf Difference Equations and Semi-Cardinal Interpolation with Integrable Convolution Kernels

Constructive Approximation, 2023
AbstractLet$$H\subset {\mathbb {Z}}^d$$H⊂Zdbe a half-space lattice, defined either relative to a fixed coordinate (e.g.$$H = {\mathbb {Z}}^{d-1}\!\times \!{\mathbb {Z}}_+$$H=Zd-1×Z+), or relative to a linear order$$\preceq $$⪯on$${\mathbb {Z}}^d$$Zd, i.e.$$H = \{j\in {\mathbb {Z}}^d: 0\preceq j\}$$H={j∈Zd:0⪯j}.
