  • An overview of the situation of hand surgery in Spain during the peak of COVID-19 pandemic. [Journal Article]
    Hand Surg Rehabil. 2020 Jun 30 [Online ahead of print]Martin-Playa P, Calzacorta-Muñoz P, … García Gutiérrez JJ
  • Since the first cases were detected in China in December 2019, the COVID-19 pandemic has spread rapidly, collapsing many healthcare systems, and forcing them to adapt. Hand surgery has been indirectly affected by this scenario. This article aims to provide an overview on how Spanish hand surgeons have modified their daily practice. Based on a survey conducted nationwide, we observed a decrease in…
  • Bruma MAD: a new way of treating OSAS patients. [Journal Article]
    J Biol Regul Homeost Agents. 2020 May-Jun; 34(3 Suppl. 1):165-171.DENTAL SUPPLEMENT, Quinzi V, … Lo Giudice A
  • The aim of this study was to introduce a new adjustable device in the treatment of obstructive sleep apnea syndrome (OSAS). The new appliance has a different way to regulate and move the mandible through the presence of two occlusal lifts, that can leave an open posterior space, and the complex system formed by the peduncle and the steel plate that can easily move forward the mandible. This syste…
  • [COVID-19 - A RECENT REVIEW]. [Review]
    Harefuah. 2020 Jun; 159(6):394-397.Levinger U
  • Corona disease sprang into our lives towards the end of 2019. In November/December 2019, in Wuhan, Hubei province in China, a SARS-like viral disease with a high adhesive capacity and the potential to endanger the life of the patient was reported. It soon became clear that the disease was very contagious and new hospitals were being built on the site and a General closure was underway. Many docto…
  • Catalysis effect on CO2 methanation using MgH2 as a portable hydrogen medium. [Journal Article]
    Phys Chem Chem Phys. 2020 Jun 24 [Online ahead of print]Amica G, Azcona SR, … Gennari FC
  • The feasibility of the reduction of CO2 to CH4 employing MgH2 in the presence and absence of cobalt as a catalyst was investigated for the first time, exploring different non-independent reaction conditions such as the grade of microstructural refinement, the molar ratio MgH2 : CO2, reaction time and temperature. For the un-catalyzed process a methane yield of 44.6% was obtained after 24 h of the…
  • Erdós-Rényi phase transition in the Axelrod model on complete graphs. [Journal Article]
    Phys Rev E. 2020 May; 101(5-1):052319.Pinto S, Balenzuela P
  • The Axelrod model has been widely studied since its proposal for social influence and cultural dissemination. In particular, the community of statistical physics focused on the presence of a phase transition as a function of its two main parameters, F and Q. In this work, we show that the Axelrod model undergoes a second-order phase transition in the limit of F→∞ on a complete graph. This transit…
  • Spectral theory of soliton and breather gases for the focusing nonlinear Schrödinger equation. [Journal Article]
    Phys Rev E. 2020 May; 101(5-1):052207.El G, Tovbis A
  • Solitons and breathers are localized solutions of integrable systems that can be viewed as "particles" of complex statistical objects called soliton and breather gases. In view of the growing evidence of their ubiquity in fluids and nonlinear optical media, these "integrable" gases present a fundamental interest for nonlinear physics. We develop an analytical theory of breather and soliton gases …
  • Secure Collapsing Method Based on Fully Homomorphic Encryption. [Journal Article]
    Stud Health Technol Inform. 2020 Jun 16; 270:412-416.Niyitegeka D, Bellafqira R, … Coatrieux G
  • In this paper, we propose a new approach for performing privacy-preserving genome-wide association study (GWAS) in cloud environments. This method allows a Genomic Research Unit (GRU) who possesses genetic variants of diseased individuals (cases) to compare his/her data against genetic variants of healthy individuals (controls) from a Genomic Research Center (GRC). The originality of this work st…
  • How Wettability Controls Nanoprinting. [Journal Article]
    Phys Rev Lett. 2020 Jun 05; 124(22):224503.Fernández-Toledano JC, Braeckeveldt B, … De Coninck J
  • Using large scale molecular dynamics simulations, we study in detail the impact of nanometer droplets of low viscosity on flat substrates versus the wettability of the solid plate. The comparison between the molecular dynamics simulations and different macroscopic models reveals that most of these models do not correspond to the simulation results at the nanoscale, in particular for the maximal c…
  • AKI and Collapsing Glomerulopathy Associated with COVID-19 and APOL1 High-Risk Genotype. [Journal Article]
    J Am Soc Nephrol. 2020 Jun 19 [Online ahead of print]Wu H, Larsen CP, … Velez JCQ
  • CONCLUSIONS: Collapsing glomerulopathy in black patients with COVID-19 was associated with high-risk APOL1 variants. We found no direct viral infection in the kidneys, suggesting a possible alternative mechanism: a "two-hit" combination of genetic predisposition and cytokine-mediated host response to SARS-CoV-2 infection. Given this entity's resemblance with HIV-associated nephropathy, we propose the term COVID-19-associated nephropathy to describe it.
  • How canyons evolve by incision into bedrock: Rainbow Canyon, Death Valley National Park, United States. [Journal Article]
    Proc Natl Acad Sci U S A. 2020 Jun 15 [Online ahead of print]Zhang L, Li T, … Parker G
  • Incising rivers may be confined by low-slope, erodible hillslopes or steep, resistant sidewalls. In the latter case, the system forms a canyon. We present a morphodynamic model that includes the essential elements of a canyon incising into a plateau, including 1) abrasion-driven channel incision, 2) migration of a canyon-head knickpoint, 3) sediment feed from an alluvial channel upstream of the k…
