Critical Branching Brownian Motion with Killing

open access: yes, 2015
We obtain sharp asymptotic estimates for hitting probabilities of a critical branching Brownian motion in one dimension with killing at 0 We also obtain sharp asymptotic formulas for the tail probabilities of the number of particles killed at 0.

Current Tracking Adaptive Control of Brushless DC Motors

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Asymptotic Behaviour of Solutions of n-th Order Ordinary Differential Equations with Regularly Varying Nonlinearities .

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
In the paper the question of existence and asymptotic behaviour of P k +∞(λ0)–solutions, k ∈ {3, . . . , n} and λ0 ∈ {1, ±∞}, of a binomial non-autonomous n-th order ordinary differential equation with regularly varying nonlinearities was investigated ...

ABEL-TAUBER PROCESS AND ASYMPTOTIC FORMULAS

open access: yesKyushu Journal of Mathematics, 2017
Summary: The Abel-Tauber process consists of the abelian process of forming the Riesz sums and the subsequent Tauberian process of differencing the Riesz sums, an analogue of the integration-differentiation process. In this article, we use the Abel-Tauber process to establish an interesting asymptotic expansion for the Riesz sums of arithmetic ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Asymptotic Estimates for Second Kind Generalized Stirling Numbers

open access: yesJournal of Applied Mathematics, 2013
Asymptotic formulas for the generalized Stirling numbers of the second kind with integer and real parameters are obtained and ranges of validity of the formulas are established.

Approximations of Shannon Mutual Information for Discrete Variables with Applications to Neural Population Coding

open access: yesEntropy, 2019
Although Shannon mutual information has been widely used, its effective calculation is often difficult for many practical problems, including those in neural population coding.

A Soft Microrobot for Single‐Cell Transport, Spheroid Assembly, and Dual‐Mode Drug Screening

open access: yesAdvanced Materials, EarlyView.
A soft, untethered hydrogel microrobot enables precise single‐cell delivery, self‐assembly into 3D spheroids, and real‐time thermal actuation. Driven by light‐induced convection and embedded with gold nanorods and temperature sensors, the microrobot guides cells, modulates local microenvironments, and supports drug testing.

Random intersection graph process

open access: yes, 2013
We introduce a random intersection graph process aimed at modeling sparse evolving affiliation networks that admit tunable (power law) degree distribution and assortativity and clustering coefficients.

Spectral Tuning of Hyperbolic Shear Polaritons in Monoclinic Gallium Oxide via Isotopic Substitution

open access: yesAdvanced Materials, EarlyView.
Spectral tuning of highly directional hyperbolic shear polaritons is realized via isotopic substitution of 16O to 18O in monoclinic β$\beta$‐phase gallium oxide. A red‐shift of almost 40 cm−1 is experimentally demonstrated with near‐field imaging, corroborated by the permittivity change extracted from far‐field experiments and density functional theory.
