Low-defect quantum dot lasers directly grown on silicon analyzed using cross-sectional scanning tunneling microscopy and spectroscopy

Konstantinos Papatryfonos, Jean-Christophe Girard, Mingchu Tang, Christophe David, Alwyn Seeds, Guillemin Rodary, Huiyun Liu, David Selviah

<div><p>Monolithic integration of III-V lasers on silicon is a central objective of silicon photonics, yet direct heteroepitaxy remains challenged by lattice and thermal-expansion mismatches that generate dislocations and other extended defects. Here we report an optimized molecular…

Fundamental thermovisco mechanical interactions governing the acoustic response of laser-excited nanoparticles

Stefano Giordano, Michele Diego, Francesco Banfi, Michele Brun

In this work, we investigate the thermoacoustic generation and propagation of spherical waves in a viscous fluid induced by a laser-heated spherical particle. Periodic laser excitation gives rise to two coupled mechanisms of acoustic emission. Heat transfer from the particle to the surrounding…

Coexistence and interplay of Fabry–Pérot and twin Friedrich–Wintgen bound states in the continuum in a plasmonic double T-cavity

Amina Rezzouk, Soufyane Khattou, Madiha Amrani, Adnane Noual, El Houssaine El Boudouti, Bahram Djafari-Rouhani

Bound states in the continuum (BICs) are typically investigated in terms of distinct formation mechanisms, such as symmetry-protected (SP), Friedrich–Wintgen (FW), or Fabry–Pérot (FP) BICs. However, their coexistence and mutual interaction within a single plasmonic architecture have not been…

Deciphering the dysfunctional immunological synapse in acute myeloid leukemia through microfluidic

Sofia Titah, Clara Lewuillon, Faruk Azam Shaik, Aurelie Guillemette, Eva Gez, Nathalie Jouy, Laure Goursaud, Celine Berthon, Salomon Manier, Carine Brinster, William Langue, Tzung Hsuen Khoo, Alexandre Poulain, Sophie Dabo-Niang, Dominique Collard, Bruno Quesnel, Loic Lemonnier, Mehmet Cagatay Tarhan, Yasmine Touil

Abstract Minimal residual disease (MRD) in acute myeloid leukemia (AML) arises from residual leukemic cells that resist chemotherapy and evade immune surveillance, notably through the PD-1/PD-L1 immune checkpoint. These persistent cells are the main source of relapse. Our working hypothesis is that…

Electrostatic force regularization for neural structured pruning

Abdesselam Ferdi, Abdelmalik Taleb-Ahmed, Amir Nakib, Youcef Ferdi

The demand for deploying deep convolutional neural networks (DCNNs) on resource-constrained devices for real-time applications remains substantial. However, existing state-of-the-art structured pruning methods often involve intricate implementations, require modifications to the original network…

Polymer Based Photonic Crystals Textiles for Infrared Wave Control

Charlotte Demullier, Yan Pennec, Bahram Djafari-Rouhani, Cyril Calmettes, Fabien Salaün

This paper proposes the design of photonic crystal textiles made from multifilament yarns of low-refractive-index polymers for active infrared fabric and thermoregulation or camouflage functionalities, while being comfortable and easy-to-wear. Transmission and reflection spectra are calculated as a…

Experimental and DFT study of the structural, electronic, and thermoelectrical properties of Li3xLa2/3-xTiO3 (x = 0.125) ceramic leads free for battery applications

Hicham Kacimi-Naciri, Meriem Ben Zennou, Assia Mabrouk, Amine El Azizi, Mohamed Loutou, Mohammed Mansori, Rachid Amrousse, Nadia Faska, Ahmed Bachar

We synthesized Li3xLa2/3− xTiO3 (LLTO, x = 0.125) via solid-state sintering, yielding a structurally stable orthorhombic perovskite with high environmental compatibility. The resulting material was characterized experimentally through X-ray diffraction (XRD), dielectric measurements (permittivity…
