A newly-recorded species of the genus Rhodotritoma Arrow, 1925 (Coleoptera, Erotylidae) from China [PDF]

open access: yesBiodiversity Data Journal, 2022
The genus Rhodotritoma Arrow, 1925 (Coleoptera, Erotylidae, Erotylinae, Tritomini) includes 12 known species worldwide, including three species distributed in China. In the last four decades, no work was conducted on Rhodotritoma in China. In this paper,

Processing of Flavor-Enhanced Oils: Optimization and Validation of Multiple Headspace Solid-Phase Microextraction-Arrow to Quantify Pyrazines in the Oils

open access: yesLife, 2021
An efficient and effective multiple headspace-solid phase microextraction-arrow-gas chromatography-mass spectrometry (MHS-SPME-arrow-GCMS) analytical protocol is established and used to quantify the flavor compounds in oils.

Relating the thermodynamic arrow of time to the causal arrow

open access: yes, 2007
Consider a Hamiltonian system that consists of a slow subsystem S and a fast subsystem F. The autonomous dynamics of S is driven by an effective Hamiltonian, but its thermodynamics is unexpected.

Fundamentality and Time’s Arrow [PDF]

open access: yesPhilosophy of Science, 2018
The distribution of matter in our universe is strikingly time asymmetric. Most famously, the Second Law of Thermodynamics says that entropy tends to increase toward the future but not toward the past. But what explains this time-asymmetric distribution of matter?

THE LOGICAL CONTRADICTIONS OF THE TIME REVERSIBILITY AND THEIR SOLUTIONS IN PHILOSOPHY AND SCIENCE OF XX-XXI CENTURIES

open access: yesВестник Мининского университета, 2018
Introduction: the purpose of this article is to highlight the main difficulties and paradoxes, which connected with the time reversibility and also to research their solutions in the context of philosophy and natural science.

The Origin of Time Asymmetry

open access: yes, 1993
It is argued that the observed Thermodynamic Arrow of Time must arise from the boundary conditions of the universe. We analyse the consequences of the no boundary proposal, the only reasonably complete set of boundary conditions that has been put forward.

Quantum Cosmology and the Arrow of Time

open access: yes, 2005
Although most fundamental laws are invariant under time reversal, experience exhibits the presence of irreversible phenomena -- the arrows of time. Their origin lies in cosmology, and I argue that only quantum cosmology can provide the appropriate formal

Feedback Control and the Arrow of Time

open access: yes, 2008
The purpose of this paper is to highlight the central role that the time asymmetry of stability plays in feedback control. We show that this provides a new perspective on the use of doubly-infinite or semi-infinite time axes for signal spaces in control ...

Time's Arrow

open access: yesTime's Arrow
Our cards model shows two world-views, but as far as we look at the sequence constructed, we can't see them. By making a ring with any sequence constructed in a cards model, we can represent two different time series in terms of two opposite directions of the ring rotation. Using this device, we can restate the thermodynamic discussions.

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.
