The impact of CTLA-4 blockade and interferon-α on clonality of T-cell repertoire in the tumor microenvironment and peripheral blood of metastatic melanoma patients

open access: yesOncoImmunology, 2019
Patients with metastatic melanoma were treated with tremelimumab and interferon-α (IFN) in a previously reported clinical trial [NCT00610857]. Responses were assessed by RECIST criteria as complete (CR) or partial (PR), stable disease (SD) or progressive

Adaptive Gradient Estimation Stochastic Parallel Gradient Descent Algorithm for Laser Beam Cleanup

open access: yesPhotonics, 2021
For a high-power slab solid-state laser, obtaining high output power and high output beam quality are the most important indicators. Adaptive optics systems can significantly improve beam qualities by compensating for the phase distortions of the laser ...

Morality, Adapted [PDF]

open access: yesPerspectives in Biology and Medicine, 2010
Over the last few decades, scientists have been busy debunking the myth that nonhuman animals relate to each other in a primarily competitive, aggressive way. What they have found is that many species of animal, including many of those most closely related to humans, display a remarkable range of cooperative, "prosocial" behavior.

Adaptive hypermedia for education and training [PDF]

open access: yes, 2012
Adaptive hypermedia (AH) is an alternative to the traditional, one-size-fits-all approach in the development of hypermedia systems. AH systems build a model of the goals, preferences, and knowledge of each individual user; this model is used throughout ...

Design and Experimental Validation of a Model-Free Controller for Beam Stabilization in Adaptive Optics Systems

open access: yesIEEE Photonics Journal
Stabilization of optical beams has always been a key factor affecting the performance of many optical systems. The Adaptive optics (AO) beam stabilization system requires further development to cope with increasingly complex application scenarios and ...

Improving the cotton simulation model, GOSSYM, for soil, photosynthesis, and transpiration processes

open access: yesScientific Reports, 2023
GOSSYM, a mechanistic, process-level cotton crop simulation model, has a two-dimensional (2D) gridded soil model called Rhizos that simulates the below-ground processes daily. Water movement is based on gradients of water content and not hydraulic heads.

Optimization of Iterative Control Algorithms for High-Resolution Adaptive Optics Systems

open access: yesIEEE Photonics Journal
As the number of wavefront sensor subapertures and deformable mirror actuators in adaptive optics systems increases, the computational time of the direct gradient wavefront control algorithm is excessively long, which is a major factor affecting the ...

Self-adaptive moving mesh schemes for short pulse type equations and their Lax pairs [PDF]

open access: yes, 2014
Integrable self-adaptive moving mesh schemes for short pulse type equations (the short pulse equation, the coupled short pulse equation, and the complex short pulse equation) are investigated.
