DS-IRSA: A Deep Reinforcement Learning and Sensing Based IRSA

GLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023
One of the main difficulties to enable the future scaling of IoT networks is the issue of massive connectivity. Recently, Modern Random Access protocols have emerged as a promising solution to provide massive connections for IoT. One main protocol of this family is Irregular Repetition Slotted Aloha (IRSA), which can asymptotically reach the optimal ...

Deep Learning, Sensing-based IRSA (DS-IRSA): Learning a Sensing Protocol with Deep Reinforcement Learning

, 2022
Irregular Repetition Slotted Aloha (IRSA) est un candidat d’une famille de protocoles d’accès aléatoire pour résoudre le problème de la connectivité massive pour les réseaux de l’internet des objets (IoT). Les principales caractéristiques de ce protocole sont de permettre aux utilisateurs de répéter leurs paquets plusieurs fois dans la même trame et d ...

IRSA Transmission Optimization via Online Learning

CoRR, 2018
In this work, we propose a new learning framework for optimising transmission strategies when irregular repetition slotted ALOHA (IRSA) MAC protocol is considered. We cast the online optimisation of the MAC protocol design as a multi-arm bandit problem that exploits the IRSA structure in the learning framework. Our learning algorithm quickly learns the

Asymmetric Dual‐Electron Bridge Via Gradient Orbital Coupling for Robust Alkaline Oxygen Evolution in Low‐Iridium Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas

Conservation Biology, EarlyView.
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Impact of chromophores on colour appearance in a computational skin model [PDF]

, 2020
Early diagnosis of skin cancer offers the patient more favorable treatment options. Color fidelity of skin images is a major concern for dermatologists as adoption of digital dermatoscopes is increasing rapidly. Accurate color depiction of the lesion and

Shelters or ecological traps? Context‐dependent effects of nestboxes on breeding success in a colonial raptor

Ibis, EarlyView.
Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

The Bolocam Galactic Plane Survey: Survey Description and Data Reduction [PDF]

, 2010
We present the Bolocam Galactic Plane Survey (BGPS), a 1.1 mm continuum survey at 33" effective resolution of 170 square degrees of the Galactic Plane visible from the northern hemisphere. The survey is contiguous over the range -10.5 < l < 90.5, |b| < 0.

Food Gifting and Household Food Security

Review of Development Economics, EarlyView.
ABSTRACT Food gifting provides an important means of risk sharing in agrarian economies where farming households have limited access to formal credit and insurance markets. Food gifting is also an important source of food for households that are struggling with food scarcity.
