Electrical Maxwell demon and Szilard engine utilizing Johnson noise, measurement, logic and control. [PDF]
We introduce a purely electrical version of Maxwell's demon which does not involve mechanically moving parts such as trapdoors, etc. It consists of a capacitor, resistors, amplifiers, logic circuitry and electronically controlled switches and uses ...

The evidence for old age motor neuron death: A scoping review
We systematically evaluated the extant literature on age‐related motor neuron (MN) death in aging, focusing on studies directly assessing MNs. We show that in the spinal cord and brainstem, there is robust evidence for MN loss, particularly in the human spinal cord. In rats, MN loss was readily observed across a variety of labelling methods and regions,

Axiomatic Information Thermodynamics
We present an axiomatic framework for thermodynamics that incorporates information as a fundamental concept. The axioms describe both ordinary thermodynamic processes and those in which information is acquired, used and erased, as in the operation of ...

Beating the Thermal Limit of Qubit Initialization with a Bayesian Maxwell’s Demon
Fault-tolerant quantum computing requires initializing the quantum register in a well-defined fiducial state. In solid-state systems, this is typically achieved through thermalization to a cold reservoir, such that the initialization fidelity is ...

Experimental methods in chemical engineering: Atomic absorption spectrometry—AAS
Abstract Elements absorb electromagnetic radiation (light) of a specific wavelength in proportion to the number of atoms in its path. As the atoms absorb this light energy, electrons rise from the ground state to an excited state. In atomic absorption spectrometry (AAS), high temperatures produce clouds of atoms from the sample (atomization) and ...

Limits of Landauer’s principle and of the second law of thermodynamics
Since 1857, the second law of thermodynamics has faced the challenge of Maxwell’s imagined demon. The widely accepted response to this challenge suggests that the demon requires a bit of information to work, and according to Landauer’s principle ...

Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

Maxwell’s Demon Is Foiled by the Entropy Cost of Measurement, Not Erasure
I dispute the conventional claim that the second law of thermodynamics is saved from a “Maxwell’s demon” by the entropy cost of information erasure and show that instead it is measurement that incurs the entropy cost.

The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

A Modified Szilard's Engine: Measurement, Information, and Maxwell's Demon
: Using an isolated measurement process, I've calculated the effect measurement has on entropy for the multi-cylinder Szilard engine. This calculation shows that the system of cylinders possesses an entropy associated with cylinder total energy states ...
