Brain tissue classification in hyperspectral images using multistage diffusion features and transformer

open access: yesJournal of Microscopy, EarlyView.
Abstract Brain surgery is a widely practised and effective treatment for brain tumours, but accurately identifying and classifying tumour boundaries is crucial to maximise resection and avoid neurological complications. This precision in classification is essential for guiding surgical decisions and subsequent treatment planning.

Optical phase‐sensitive amplification of higher‐order QAM signal with single Mach–Zehnder amplitude modulator

open access: yesElectronics Letters, 2021
An optical phase‐sensitive amplifier (PSA) has the potential of low‐noise optical amplification. A frequency non‐degenerate PSA (ND‐PSA) can amplify arbitrary modulation formats including higher‐order QAM.

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs

open access: yesJournal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.
ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Density‐Valued ARMA Models by Spline Mixtures

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT This paper proposes a novel framework for modeling time series of probability density functions by extending autoregressive moving average (ARMA) models to density‐valued data. The method is based on a transformation approach, wherein each density function on a compact domain [0,1]d$$ {\left[0,1\right]}^d $$ is approximated by a B‐spline ...

M $\times$ N Wavelength Selective Switches Using Beam Splitting By Space Light Modulators

open access: yesIEEE Photonics Journal, 2016
We propose a multiple-input-multiple-output (M $\times$ N) optical switch with the same optical system as that used for a single-input-multiple-output (1 $\times$ N) switch based on a liquid crystal on silicon (LCOS).
