Rational nef and anti-nef polytopes are not uniform

, 2021
We give two examples which show that rational nef and anti-nef polytopes are not uniform even for klt surface pairs, answering a question of Chen-Han. We also show that rational nef polytopes are uniform when the Cartier indices are uniformly bounded.

U.S. Agriculture, Biofuel Markets, and Trade: Challenges and Opportunities

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Using an enhanced Computable General Equilibrium (CGE) model (GTAP‐BIO), this study assesses how the expansion in demand for Electric Vehicles (EVs) and the reduction in exports of agricultural products induced by trade disputes negatively affect US agriculture.

Association with PAK2 Enables Functional Interactions of Lentiviral Nef Proteins with the Exocyst Complex

mBio, 2015
Human immunodeficiency virus type 1 (HIV-1) Nef enhances virus replication and contributes to immune evasion in vivo, but the underlying molecular mechanisms remain incompletely defined.

La nef

, 2010
La nef comporte 11 travées sensiblement égales, limitées par de solides piliers composés, au flanc desquels un faisceau de colonnettes monte, d’un jet, pour recevoir, bien haut, les retombées des voûtes d’ogives, donnant à l’édifice le bel élan vertical ...

Proteomic analysis of HIV-1 Nef cellular binding partners reveals a role for exocyst complex proteins in mediating enhancement of intercellular nanotube formation

Retrovirology, 2012
Background HIV-1 Nef protein contributes to pathogenesis via multiple functions that include enhancement of viral replication and infectivity, alteration of intracellular trafficking, and modulation of cellular signaling pathways.

HIV-1 Nef down-modulates C-C and C-X-C chemokine receptors via ubiquitin and ubiquitin-independent mechanism. [PDF]

PLoS ONE, 2014
Human and Simian Immunodeficiency virus (HIV-1, HIV-2, and SIV) encode an accessory protein, Nef, which is a pathogenesis and virulence factor. Nef is a multivalent adapter that dysregulates the trafficking of many immune cell receptors, including ...

The identification of a small molecule compound that reduces HIV-1 Nef-mediated viral infectivity enhancement.

PLoS ONE, 2011
Nef is a multifunctional HIV-1 protein that accelerates progression to AIDS, and enhances the infectivity of progeny viruses through a mechanism that is not yet understood.

Molecular Determinants of Nef Function

Journal of Biomedical Science, 1997
The human immunodeficiency virus (HIV), the causative agent of the acquired immune deficiency syndrome (AIDS), in addition to encoding for the gag, pol and env structural genes common to all retroviruses also encodes six accessory genes: tat, rev, nef, vpr, vpu and vif. These accessory genes are responsible for the regulation of HIV replication. Recent

Evaluation of Varnishes to Slow Down the Aging of Plasticized PVC

Journal of Applied Polymer Science, EarlyView.
Varnish effectiveness in plasticized PVC strongly depends on both formulation and degradation state. A polyurethane varnish effectively limits color change and plasticizer loss in unaged PVC without phosphate plasticizers, whereas no protective effect is observed for phosphate‐containing PVC.

Nef‘î’nin Şiirinde Siyaset Düşüncesi ve Memduhun İstidadı Olarak Cevher

Turcology Research
Cevher Antik Yunan döneminden bu yana felsefenin konusu olmuştur. Aristoteles’in Kategoriler’de etraflıca belirttiği fikirleri cevherin asla bir mevzuda bulunmaması ilkesine dayanmaktadır. Bütün arazların kendisine yüklendiği temel kategori olan cevherin
