Advances in deep‐tissue fluorescence imaging through optical clearing: A review

open access: yesVIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

On Finite and Infinite Sums of the Modified Bessel Function of the First Kind

open access: yesMediterranean Journal of Mathematics
Abstract This paper derives novel finite-sum expressions for the modified Bessel function of the first kind using properties of the Marcum Q function. Limits to infinite sums give expressions that are equivalent but frequently more compact when compared with results in the ...

A Dual‐Frequency Sensitivity Model for Optical Fibre Ultrasonic Sensors in Power Transformer Partial Discharge Detection

open access: yesHigh Voltage, EarlyView.
ABSTRACT The detection of partial discharges (PD) on the power transformer tank demands higher sensitivity in ultrasonic detection. To target the detection frequency band for sensor optimisation and enhance sensitivity, this paper presents a dual‐frequency sensitivity model for optical fibre ultrasonic sensors.

Spatial signatures of group cohesion

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Wildlife populations are undergoing unprecedented changes to their spatial distributions as a result of human activities. Innovative approaches are needed to document these changes, especially in cases where sampling is sparse. Here, we contribute to the tools available in spatial ecology by developing novel metrics based on the coefficient of

Optimized and Aligned Anisotropic Monte Carlo Sampling Patterns

open access: yesComputer Graphics Forum, EarlyView.
Abstract Path tracing uses Monte Carlo integration to solve the rendering equation by evaluating the integrand at random sampling points. The convergence rate of the error can be significantly improved by using correlated instead of random sampling, especially on smooth integrands.

Integrated Engineering of CAR‐T Cells for Solid Tumours

open access: yesCell Proliferation, EarlyView.
Solid tumours pose multifactorial barriers including antigen heterogeneity, immunosuppressive microenvironment, and poor T‐cell trafficking, limiting CAR‐T efficacy compared to hematologic malignancies. Integrated engineering strategies are essential, combining logic‐gated receptors for precision, metabolic‐epigenetic reprogramming for resilience, and ...

Relative Arbitrage Opportunities With Interactions Among N Investors

open access: yesMathematical Finance, EarlyView.
ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Old dog, new trick: Charybdotoxin as a novel ryanodine receptor blocker

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The peptide toxin charybdotoxin (ChTx) from the scorpion Leiurus quinquestriatus was tested on single‐channel currents of the ryanodine receptor incorporated into planar lipid bilayers. The structure–function relationship of ChTx was investigated using toxin variants generated by isosteric substitutions of the basic amino acids ...

Frequency‐dependent contraction rates for the Bayesian method to the inverse source problem

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract This paper addresses an inverse source problem for acoustic waves in a range of frequencies. Our study has two main goals. First, although the problem is severely ill‐posed with a logarithmic stability estimate, we demonstrate, through careful analysis of the forward map's singular values, that increasing the frequency range enhances stability,
