Scale‐Invariant Waveguiding in Flatland

open access: yesExploration, EarlyView.
The study introduces scale‐invariant metasurface waveguides with uniform modal field distribution and an effective index independent of the core width. By leveraging spatial symmetry and fine‐tuning mode profiles, the design is validated through near‐field measurements in the C band, offering potential applications in flat optics, sensing, and ...

Heat Transfer Performance of Biphilic Surfaces With Diatomite‐Based Composite Coatings in a Closed Thermosyphon System

open access: yesHeat Transfer, EarlyView.
ABSTRACT This study investigates the thermal performance of innovative biphilic boiling surfaces designed for CPU cooling applications using a two‐phase closed thermosyphon (TPCT) system. The surfaces were fabricated by applying composite coatings—comprising epoxy resin and diatomite particles functionalized with APTES and PFOTS silanes— onto Al1050 ...

Gate tunable MoS2 memristive neuron for early fusion of visual and acoustic signals spiking neural network

open access: yesInfoMat, EarlyView.
Current brain‐inspired computing chips require complex additional circuits to operate effectively, making them bulky and inefficient. We have created a single adjustable artificial neuron device made from MoS2 that can dynamically modulate its behavior on demand, eliminating the need for extra circuits and enabling it to process different types of ...

Excitable behaviors

open access: yes, 2017
This chapter revisits the concept of excitability, a basic system property of neurons. The focus is on excitable systems regarded as behaviors rather than dynamical systems.

A prototype submersible sheathless flow cytometer designed for autonomous platforms

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Development of submersible flow cytometers has allowed for continuous, in situ measurements of natural assemblages of phytoplankton cells. Here we introduce DeepCyte, a sensitive prototype submersible flow cytometer developed for deployment on autonomous platforms.

Convergence Deficits in Myoclonus‐Dystonia Point to Cerebellar Impairment

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Myoclonus‐dystonia (M‐D) is a monogenic movement disorder, with proposed cerebellar dysfunction. Vergence eye movement deficits, characteristics of degenerative cerebellar disease, have not been studied in M‐D. Cerebellar transcranial alternating current stimulation (tACS) is considered a potential therapeutic approach.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

open access: yesNordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

High‐Precision Measurement of Time Delay with Frequency‐Resolved Hong‐Ou‐Mandel Interference of Weak Coherent States

open access: yesAdvanced Quantum Technologies, EarlyView.
High‐precision time‐delay measurements are demonstrated using frequency‐resolved Hong‐Ou Mandel (HOM) interference with weak coherent states. The method, by exploiting the quantum eraser phenomenon, achieves low uncertainty even for delays exceeding the photon coherence time, where traditional HOM interferometry fails, thus confirming theoretical ...

Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

open access: yesAdvanced Quantum Technologies, EarlyView.
A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.

End‐to‐End Portfolio Optimization with Hybrid Quantum Annealing

open access: yesAdvanced Quantum Technologies, EarlyView.
This works presents a hybrid quantum‐classical framework for portfolio optimization that combines quantum assisted asset selection and rebalancing with classical weight allocation. The approach processes real market data, embeds it into Quadratic Unconstrained Binary Optimization formulations, and evaluates performance within a unified workflow ...
