Scattering Amplitudes and Conservative Binary Dynamics at O(G^{4}). [PDF]
Physical Review Letters, 2021 Using scattering amplitudes, we obtain the potential contributions to conservative binary dynamics in general relativity at fourth post-Minkowskian order O(G^{4}).

Mildly Conservative Q-Learning for Offline Reinforcement Learning [PDF]
Neural Information Processing Systems, 2022 Offline reinforcement learning (RL) defines the task of learning from a static logged dataset without continually interacting with the environment. The distribution shift between the learned policy and the behavior policy makes it necessary for the value

Scattering Amplitudes and the Conservative Hamiltonian for Binary Systems at Third Post-Minkowskian Order. [PDF]
Physical Review Letters, 2019 We present the amplitude for classical scattering of gravitationally interacting massive scalars at third post-Minkowskian order. Our approach harnesses powerful tools from the modern amplitudes program such as generalized unitarity and the double-copy ...

Initial Invasive or Conservative Strategy for Stable Coronary Disease.
New England Journal of Medicine, 2020 BACKGROUND Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain.

Early Surgery or Conservative Care for Asymptomatic Aortic Stenosis.
New England Journal of Medicine, 2020 BACKGROUND The timing and indications for surgical intervention in asymptomatic patients with severe aortic stenosis remain controversial. METHODS In a multicenter trial, we randomly assigned 145 asymptomatic patients with very severe aortic stenosis ...

Conservative treatment of knee osteoarthritis: A review of the literature
World Journal of Orthopaedics, 2022 Knee osteoarthritis (KOA) is a common chronic debilitating disease with an estimated prevalence of 23.9% in the general adult population. The condition is characterised by joint pain, functional impairment and significant reduction in quality of life ...

Conservative Oxygen Therapy during Mechanical Ventilation in the ICU.
New England Journal of Medicine, 2020 BACKGROUND Patients who are undergoing mechanical ventilation in the intensive care unit (ICU) often receive a high fraction of inspired oxygen (Fio2) and have a high arterial oxygen tension.

Atypical stress femoral shaft fracture secondary to alendronate therapy
Journal of Orthopedics, Traumatology and Rehabilitation, 2020 Bisphosphonate (BP) therapy is widely used as it remains the first-line of treatment for osteoporosis. These antiresorptive drugs inhibit osteoclast function and promote apoptosis. However, atypical stress femoral fractures occurring in the diaphysis and

Health-Status Outcomes with Invasive or Conservative Care in Coronary Disease.
New England Journal of Medicine, 2020 BACKGROUND In the ISCHEMIA trial, an invasive strategy with angiographic assessment and revascularization did not reduce clinical events among patients with stable ischemic heart disease and moderate or severe ischemia. A secondary objective of the trial
