Novelty detection in rover-based planetary surface images using autoencoders

Author(s): Stefanuk B; Skonieczny K;

In the domain of planetary science, novelty detection is gaining attention because of the operational opportunities it offers, including annotated data products and downlink prioritization. Using a variational autoencoder (VAE), this work improves upon state-of-the-art novelty detection performance in the context of Martian exploration by > 7 % (measured ...

Microfluidics for long-term single-cell time-lapse microscopy: Advances and applications

Author(s): Allard P; Papazotos F; Potvin-Trottier L;

Cells are inherently dynamic, whether they are responding to environmental conditions or simply at equilibrium, with biomolecules constantly being made and destroyed. Due to their small volumes, the chemical reactions inside cells are stochastic, such that genetically identical cells display heterogeneous behaviors and gene expression profiles. Studying t ...

We're building it up to burn it down: fire occurrence and fire-related climatic patterns in Brazilian biomes

Author(s): Diele Viegas LM; Sales L; Hipólito J; Amorim C; Johnson de Pereira E; Ferreira P; Folta C; Ferrante L; Fearnside P; Mendes Malhado AC; Frederico Duarte Rocha C; M Vale M;

Background: Terrestrial biomes in South America are likely to experience a persistent increase in environmental temperature, possibly combined with moisture reduction due to climate change. In addition, natural fire ignition sources, such as lightning, can become more frequent un ...

Robust landmark-based brain shift correction with a Siamese neural network in ultrasound-guided brain tumor resection

Author(s): Pirhadi A; Salari S; Ahmad MO; Rivaz H; Xiao Y;

Purpose: In brain tumor surgery, tissue shift (called brain shift) can move the surgical target and invalidate the surgical plan. A cost-effective and flexible tool, intra-operative ultrasound (iUS) with robust image registration algorithms can effectively track brain shift to ensure surgical outcomes and safety. Methods: We proposed to employ a Siamese ...

Lymph Node Metastases Detection Using Gd2O3@PCD as Novel Multifunctional Contrast Imaging Agent in Metabolic Magnetic Resonance Molecular Imaging

Author(s): Rasouli Z; Riyahi-Alam N; Khoobi M; Haghgoo S; Gholibegloo E; Ebrahimpour A; H A; Hashemi H;

Axillary lymph node detection is crucial to staging and prognosis of the lymph node metastatic spread in breast cancer. Currently, lymphoscintigraphy and blue dye, as the conventional methods to localize sentinel lymph nodes (SLNs), are invasive and can only be performed during surgery. This stud ...

A spin modulating device, tuned by the Fermi energy, in honeycomb-like substrates periodically stubbed with transition-metal-dichalkogenides

Author(s): Belayadi A; Vasilopoulos P;

We investigate spin transport through graphene-like substrates stubbed vertically with transition-metal-dichalkogenides (TMDs). A tight-binding model is used based on a graphene-like Hamiltonian that includes di?erent types of spin-orbit coupling (SOC) terms permitted by the C3v symmetry group in TMDs/graphene-like heterostructures. The results show a spi ...

Recommendations for making editorial boards diverse and inclusive

Author(s): Mahdjoub H; Maas B; Nuñez MA; Khelifa R;

Lack of diversity in editorial boards hinders multifaceted perspectives in fields such as ecology, evolution, and conservation. We outline ten key actions for editorial boards to promote equity, diversity, and inclusion, benefiting the journal in attracting a wider readership, enhancing diversity among authors, and overcoming biases in editorial decisions.

Surfactant-enhanced mobilization of persistent organic pollutants: Potential for soil and sediment remediation and unintended consequences

Author(s): Bolan S; Padhye LP; Mulligan CN; Alonso ER; Saint-Fort R; Jasemizad T; Wang C; Zhang T; Rinklebe J; Wang H; Siddique KHM; Kirkham MB; Bolan N;

This review aims to provide an overview of the sources and reactions of persistent organic pollutants (POPs) and surfactants in soil and sediments, the surfactant-enhanced solubilisation of POPs, and the unintended consequences of surfactant-induced remediation of soil and sediments contaminated ...

The influence of inter-bubble spacing on the resonance response of ultrasound contrast agent microbubbles

Author(s): Yusefi H; Helfield B;

Ultrasound-driven microbubbles, typically between 1 and 8 µm in diameter, are resonant scatterers that are employed as diagnostic contrast agents and emerging as potentiators of targeted therapies. Microbubbles are administered in populations whereby their radial dynamics - key to their effectiveness - are greatly affected by intrinsic (e.g. bubble size) ...

Mapping pontocerebellar connectivity with diffusion MRI

Author(s): Rousseau PN; Chakravarty MM; Steele CJ;

The cerebellum's involvement in cognitive, affective and motor functions is mediated by connections to different regions of the cerebral cortex. A distinctive feature of cortico-cerebellar loops that has been demonstrated in the animal work is a topographic organization that is preserved across its corticopontine, pontocerebellar, and cerebello-thalmo ...

Inhibiting amyloid beta (1-42) peptide-induced mitochondrial dysfunction prevents the degradation of synaptic proteins in the entorhinal cortex

Author(s): Olajide OJ; La Rue C; Bergdahl A; Chapman CA;

Increasing evidence suggests that mitochondrial dysfunction and aberrant release of mitochondrial reactive oxygen species (ROS) play crucial roles in early synaptic perturbations and neuropathology that drive memory deficits in Alzheimer's disease (AD). We recently showed that solubilized human amyloid beta peptide 1-42 (hAß1-42) causes rapid alterati ...

Learning processes in relapse to alcohol use: lessons from animal models

Author(s): Valyear MD; LeCocq MR; Brown A; Villaruel FR; Segal D; Chaudhri N;

Rationale: Alcohol use is reliably preceded by discrete and contextual stimuli which, through diverse learning processes, acquire the capacity to promote alcohol use and relapse to alcohol use. Objective: We review contemporary extinction, renewal, reinstatement, occasion setting, and sex differences research within a conditioning framework of relapse to ...
