Impact of dynamical charm quarks
We compute and compare the continuum limits of several quantities in QCD with and without a dynamical charm quark. We consider both low energy quantities, like the hadronic scales r0 and t 0 , and high energy quantities, like...
B-hadron production in NNLO QCD
We calculate, for the first time, the NNLO QCD corrections to identified
heavy hadron production at hadron colliders. The calculation is based on a
flexible numeric framework which allows the calculation of any distribution of

Feb 13, 2020
The type II restriction endonuclease TseI recognizes the DNA target sequence 5'-G^CWGC-3' (where W = A or T) and cleaves after the first G to produce fragments with three-base 5'-overhangs. We have determined that it is a...

Following activation, T cells rapidly divide and acquire effector functions. This energetically demanding process depends upon the ability of T cells to undergo metabolic remodeling from oxidative phosphorylation to aerobic...
T Lymphocytes in Histiocytic Sarcomas of Flat-Coated Retriever Dogs.
Flat-Coated Retriever dogs are predisposed to the development of histiocytic sarcoma (HS), a poorly differentiated, highly malignant neoplasm. The authors have previously documented a significant lymphocytic infiltrate in such...
High fidelity analysis to predict failure in T-joints
Composite T-joints and similar skin-stiffener joints have a central role in aerospace structures. However, their accurate numerical analysis is still a great challenge due to their complex geometry and stress state during...

Cancer immunotherapy frequently fails because most carcinomas have few T cells, suggesting that cancers can suppress T cell infiltration. Here, we show that cancer cells of human pancreatic ductal adenocarcinoma (PDA)...
Does the PI3K pathway promote or antagonize regulatory T cell development and function?
Regulatory T cells (Tregs) prevent autoimmunity and inflammation by suppressing the activation of other T cells and antigen presenting cells. The role of phosphoinositide 3-kinase (PI3K) signaling in Treg is controversial. Some...

Dendritic cells pulsed with protein antigens in vitro can prime antigen-specific, MHC-restricted T cells in situ
T cells recognize peptides that are bound to MHC molecules on the surface of different types of antigen-presenting cells (APC). Antigen presentation most often is studied using T cells that have undergone priming in situ, or...
