Ubiquitin E3 Ligase c-Cbl Is a Host Negative Regulator of Nef Protein of HIV-1
Frontiers in Microbiology, 2020 Nef is an accessory protein encoded by human immunodeficiency virus type-1 (HIV-1) and plays important roles in regulating HIV-1 infection and viral replication.

Mathematische Annalen, 2008 Let $X$ be a projective manifold of dimension $n$ and $L$ a strictly nef line bundle on $X$. Then $K_X+tL$ is ample if $t > n+1$ in the following cases. 1.) $\text{dim} X = 3$ unless (possibly) $X$ is a Calabi-Yau with $c_2 \cdot L=0$; 2.) $ (X) \ge n-2$; 3.) $\text{dim} (X) \ge n-2$, with $ : X \to A$ the Albanese map.

Modelling and in vitro testing of the HIV-1 Nef fitness landscape. [PDF]
, 2019 An effective vaccine is urgently required to curb the HIV-1 epidemic. We have previously described an approach to model the fitness landscape of several HIV-1 proteins, and have validated the results against experimental and clinical data.

Folie et société(s) au tournant du Moyen Âge et de la Renaissance
Babel: Littératures Plurielles, 2012 Dans le chapitre d’ouverture de son Histoire de la folie, Foucault convoque pêle-mêle différents objets pour faire naître deux idées fortes : l’emblème que constitue la Nef des fous d’une part, et d’autre part le grand partage entre expériences cosmique ...

Lower and upper bounds for nef cones [PDF]
, 2011 The nef cone of a projective variety Y is an important and often elusive invariant. In this paper we construct two polyhedral lower bounds and one polyhedral upper bound for the nef cone of Y using an embedding of Y into a toric variety. The lower bounds

On a generalized canonical bundle formula for generically finite morphisms [PDF]
, 2020 We prove a canonical bundle formula for generically finite morphisms in the setting of generalized pairs (with $\mathbb{R}$-coefficients). This complements Filipazzi's canonical bundle formula for morphisms with connected fibres.

COVID-19: What Iodine Maps From Perfusion CT can reveal—A Prospective Cohort Study
Critical Care, 2020 Background Subtraction CT angiography (sCTA) is a technique used to evaluate pulmonary perfusion based on iodine distribution maps. The aim of this study is to assess lung perfusion changes with sCTA seen in patients with COVID-19 pneumonia and correlate

Smooth and Rough Positive Currents [PDF]
, 2018 We study the different notions of semipositivity for (1,1) cohomology classes on K3 surfaces. We first show that every big and nef class (and every nef and rational class) is semiample, and in particular it contains a smooth semipositive representative ...
