A physicist solves an old thermodynamic puzzle and demonstrates directly from the second law that entropy disappears at ...

Climate scientist Kate Marvel talks to The Washington Post about the complicated mix of emotions people might feel about the changing planet.

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

We study the problem of enhancing the maximum entropy rate of Markov chains by strategically adding edges from a candidate set to a given network. We first formulate an optimization problem to ...

W = Q1 – Q2 For such system, the entropy change is calculated as ΔS = (Q2/T2– Q1/T1)Maximum work is done when the value of Q2 is very small as compared to Q1 but the value of Q2 can not be ...

Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

We study the entropy production in nonequilibrium systems described by a Fokker-Planck equation. We have devised an expression for the entropy flux in the stationary state. ... The rate of change of ...

Thermodynamics Second Law: This law that proves the dissipation of energy and heat over time, has been very essential in understanding energy and the universe through the concept of entropy. Based on ...

Entropy is a fundamental concept in thermodynamics, representing the degree of randomness or disorder in a system. In simple terms, it’s a measure of the dispersal of energy. The change in entropy is ...

Relaxing the constraint in Equation (4) also changes the log loss function from Equation (2.4) to a regularized log loss function of the form: π ~ [ - l n ( q λ ) ] + ∑ j β j | λ j | the second term ...

Entropy is a fundamental concept in thermodynamics that measures the degree of disorder or randomness in a system. It plays a vital role in understanding various processes, including heat transfer, ...
