Comprehensive Vulnerability Evaluation of Face Recognition Systems to Template Inversion Attacks via 3D Face Reconstruction.

In this article, we comprehensively evaluate the vulnerability of state-of-the-art face recognition systems to template inversion attacks using 3D face reconstruction. We propose a new method (called GaFaR) to reconstruct 3D faces from facial templates using a pretrained geometry-aware face generation network, and train a mapping from facial templates to the intermediate latent space of the face generator network. We train our mapping with a semi-supervised approach using real and synthetic face images.

Thrombolysis and thrombectomy for stroke in octogenarians and nonagenarians: A regional observational study.

Introduction: Elderly patients are a growing population in stroke units, characterized by higher frailty, but underrepresented in clinical trials about acute care. We investigated efficacy of intravenous thrombolysis (IVT) and mechanical thrombectomy (MT) in elderlies in current practice.

Methods: We assessed consecutive patients with acute ischemic stroke (AIS) hospitalized in the four stroke units of the French Northern Alps Emergency Network between 2015 and 2020.

Genome-wide cancer-specific chromatin accessibility patterns derived from archival processed xenograft tumors.

Chromatin accessibility states that influence gene expression and other nuclear processes can be altered in disease. The constellation of transcription factors and chromatin regulatory complexes in cells results in characteristic patterns of chromatin accessibility. The study of these patterns in tissues has been limited because existing chromatin accessibility assays are ineffective for archival formalin-fixed, paraffin-embedded (FFPE) tissues.

Autologous Mesenchymal Stem Cells Improve Motor Recovery in Subacute Ischemic Stroke: a Randomized Clinical Trial.

While preclinical stroke studies have shown that mesenchymal stem cells (MSCs) promote recovery, few randomized controlled trials (RCT) have assessed cell therapy in humans. In this RCT, we assessed the safety, feasibility, and efficacy of intravenous autologous bone marrow-derived MSCs in subacute stroke. ISIS-HERMES was a single-center, open-label RCT, with a 2-year follow-up.
