Article Abstract
Diffusive motion in an externally driven potential is considered. It is shown that the distribution of work required to drive the system from an initial equilibrium state to another is Gaussian for slow but finite driving. Our result is obtained by projection method techniques exploiting a small parameter defined as the switching rate between the two states of the system. The exact solution for a simple model system shows that such an expansion may fail in higher orders, since the mean and the variance following from the exact distribution show nonanalytic behavior.
To (1) assess the accuracy of the Uscom BP+ oscillometric upper-arm professional blood pressure (BP) monitor in children and adolescents as per the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018); (2) assess the suitability of a non-standard cuff; and (3) assess the impact of motion artefact on device accuracy and precision. Children and adolescents were recruited to fulfil the sex/cuff distribution criteria of the Universal Standard. Single arm sequential BP measurements were used, the test device measured on deflate with an altered child/adolescent algorithm, using three standard (Extra Small, Small Adult, Adult) and, as exploratory analysis, additionally in one non-standard cuff (Wide Range; WR) (arm circumferences: 12-17, 16-24, 22-32, 22-42 cm, respectively).
Continuous, Accurate, and detailed information on main grain land (MGL) areas is crucial for provisioning food security and making policies affecting sustainable agricultural production. It still lacks a long-term MGL distribution dataset with fine spatial resolution. This study aimed to produce a long-term, high-resolution MGL distribution map for China.
High-solid anaerobic digestion (HSAD) can be used to treat organic waste. However, the operating stability is limited by the hydraulic conditions; therefore, regulation is essential. The flow field contains a large amount of information that cannot be directly regulated.
Thermal-induced transitions between multistable states hold significant interest in stochastic thermodynamics and dynamical control with nanomechanical systems. Here, we study kinetic-energy-dependent over-barrier behaviors in the rotational degree of freedom of silica nanodumbells in tilted periodic potentials. In the rotational degree of freedom, nanodumbbells can undergo critical transitions between librations and rotations as the ellipticity of the trapping laser field changes.

Purpose: To propose a methodology for integrating the out-of-field and imaging doses to the in-field dose received by radiotherapy (RT) patients. In addition, the impact of considering the total dose in planning and radiation-induced second malignancies (RISM) risk assessment will be evaluated in several scenarios comprising photon and proton treatments.
Methods: The total dose is the voxel-wise sum of the doses from the different radiation sources (accounting for the radiobiological effectiveness) produced during the whole RT chain.
