Transformation of dynamical fluctuation into coherent energy

, 1998
Studies of noise-induced motions are showing that coherent energy can be extracted from some kinds of noise in a periodic ratchet. Recently, energetics of Langevin dynamics is formulated by Sekimoto [J.Phys.Soc.Jpn, 66 1234 (1997)], which can be ...

Dynamic calibration study [PDF]

, 1963
Since transducers used in rocket engine applications measure time varying quantities, the characteristics which define the behavior of a transducer under dynamic conditions are extremely important in their applications by the design engineer. Proper calibration of transducers in the dynamic or frequency domain required a thorough understanding of the ...

Overhauser Dynamic Nuclear Polarization To Study Local Water Dynamics [PDF]

Journal of the American Chemical Society, 2009
Surface and internal water dynamics of molecules and soft matter are of great relevance to their structure and function, yet the experimental determination under ambient and steady-state conditions is challenging. One of the most powerful approaches to measure local water dynamics within 5 A distances is to utilize the modulation of the nuclear spin ...

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

Femtosecond X-ray cross-correlation analysis of disordered crystals forming in a supercooled atomic liquid

IUCrJ
We demonstrate an advanced scattering method for accessing the 3D reciprocal space of crystalline structures forming in a rapidly supercooled noble-gas liquid using a combination of femtosecond X-ray diffraction and X-ray cross-correlation analysis.

Criticality and the Onset of Ordering in the Standard Vicsek Model [PDF]

, 2012
Experimental observations of animal collective behavior have shown stunning evidence for the emergence of large-scale cooperative phenomena resembling phase transitions in physical systems.

Dynamic Wetting on Moving Surfaces: A Molecular Dynamics Study [PDF]

ASME 2012 10th International Conference on Nanochannels, Microchannels, and Minichannels, 2012
We report molecular dynamics (MD) simulations of the dynamic wetting of nanoscale droplets on moving surfaces. The dynamic water contact angle and contact angle hysteresis are measured as a function of capillary number on smooth silicon and graphite surfaces.

Pediatric Oncology Nursing Competencies in Latin America and the Caribbean: A Scoping Review to Inform Practice, Education, and Research

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Nurses are central to cancer care for children and adolescents, yet no comprehensive synthesis has defined essential core competencies for pediatric oncology nursing (PON) practice internationally, particularly in Latin America and the Caribbean (LAC).

‘They Need to Hear You Say It’: Healthcare Professionals’ Perspectives on Barriers and Enablers to End‐of‐Life Discussions With Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT End‐of‐life conversations with adolescents and young adults (AYAs) with cancer rarely occur without the guidance of healthcare professionals. As a part of the ‘Difficult Discussions’ study, focused on palliative care and advance care planning discussions with AYAs with cancer, we investigated the factors that healthcare professionals identify ...

Resonance behavior for the dynamical friction of a system in a trapping potential

Physical Review Research, 2022
The kinetic energy fluctuation metric Ω_{K}(t) is modified to extract the dynamical friction in non-Markovian scenarios to circumvent Markovian scenarios.
