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...

Impact of iodine-induced nonplanarity on the vibrational and electronic properties of a triphenylene derivative: A combined experimental and DFT study

Ahmed Hewail, David Guérin, Christophe Krzeminski, Eric Faulques, Nataliya Kalashnyk

We present a molecular study combining Raman, infrared, and UV–visible absorption spectroscopy with density functional theory (DFT) calculations to investigate triphenylene and its iodinated derivative, 1,5,9-triiodotriphenylene. The results provide a detailed comparison of their vibrational and...

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...

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...

A Survey of Structural Attacks on Post-Quantum Cryptosystems Based on Goppa Codes: Evolution, Scope, and Impact on their Variants in the Hamming Metric

Latifa Mostari, Alban Goupil, Abdelmalik Taleb-Ahmed

With the advent of quantum computing, public-key cryptographic systems such as RSA (Rivest–Shamir–Adleman) and ECC (Elliptic Curve Cryptography) have become vulnerable to Shor’s quantum algorithm, leading to a growing interest in post-quantum cryptography. Among the post-quantum approaches, code-...

Benzo-bis(imidazole) self-assembled monolayers molecular junctions in meta or para conformation: effects of protonation on the electrical and thermal conductances.

Sergio Gonzalez Casal, Simon Pascal, Olivier Siri, Dominique Vuillaume

We report the thermal conductances of molecular junctions made of self-assembled monolayers of benzo-bis(imidazole) molecules, without side groups or functionalized with two phenylamine side groups. In the two cases, when the molecules are connected to the electrodes by thiol anchoring groups in...
