Coded Slotted ALOHA: A Graph-Based Method for Uncoordinated Multiple Access Open
In this paper, a random access scheme is introduced, which relies on the combination of packet erasure correcting codes and successive interference cancellation (SIC). The scheme is named coded slotted ALOHA. A bipartite graph representati…

The Whiteness of AI Open
This paper focuses on the fact that AI is predominantly portrayed as white—in colour, ethnicity, or both. We first illustrate the prevalent Whiteness of real and imagined intelligent machines in four categories: humanoid robots, chatbots a…

Extracting Work from Quantum Measurement in Maxwell’s Demon Engines Open
The essence of both classical and quantum engines is to extract useful energy (work) from stochastic energy sources, e.g., thermal baths. In Maxwell's demon engines, work extraction is assisted by a feedback control based on measurements p…

Retinol and ascorbate drive erasure of epigenetic memory and enhance reprogramming to naïve pluripotency by complementary mechanisms Open
Significance Naïve embryonic stem cells are characterized by genome-wide low levels of cytosine methylation, a property that may be intrinsic to their function. We found that retinol/retinoic acid (vitamin A) and ascorbate (vitamin C) syne…

Nonequilibrium Quantum Landauer Principle Open
Using the operational framework of completely positive, trace preserving operations and thermodynamic fluctuation relations, we derive a lower bound for the heat exchange in a Landauer erasure process on a quantum system. Our bound comes f…

Finite-Time Landauer Principle Open
We study the thermodynamic cost associated with the erasure of one bit of information over a finite amount of time. We present a general framework for minimizing the average work required when full control of a system's microstates is poss…

Single-Atom Demonstration of the Quantum Landauer Principle Open
One of the outstanding challenges to information processing is the eloquent suppression of energy consumption in the execution of logic operations. The Landauer principle sets an energy constraint in deletion of a classical bit of informat…

Layered Constructions for Low-Delay Streaming Codes Open
We propose a new class of error correction codes for low-delay streaming communication. We consider an online setup where a source packet arrives at the encoder every $M$ channel uses, and needs to be decoded with a maximum delay of $T$ pa…

Repairing Reed-Solomon Codes With Multiple Erasures Open
Despite their exceptional error-correcting properties, Reed-Solomon (RS) codes have been overlooked in distributed storage applications due to the common belief that they have poor repair bandwidth. A naive repair approach would require fo…

Linear-time maximum likelihood decoding of surface codes over the quantum erasure channel Open
Surface codes are among the best candidates to ensure the fault tolerance of a quantum computer. In order to avoid the accumulation of errors during a computation, it is crucial to have at our disposal a fast decoding algorithm to quickly …

Amount of fear extinction changes its underlying mechanisms Open
There has been a longstanding debate on whether original fear memory is inhibited or erased after extinction. One possibility that reconciles this uncertainty is that the inhibition and erasure mechanisms are engaged in different phases (e…

Nipples, memes, and algorithmic failure: NSFW critique of Tumblr censorship Open
In November 2018, after being suspended from Apple’s App Store for hosting child pornography, Tumblr announced its decision to ban all NSFW (not safe/suitable for work) content with the aid of machine-learning classification. The decision …

Erasure without Work in an Asymmetric Double-Well Potential Open
According to Landauer's principle, erasing a memory requires an average work of at least kTln2 per bit. Recent experiments have confirmed this prediction for a one-bit memory represented by a symmetric double-well potential. Here, we prese…

Noisy Broadcast Networks With Receiver Caching Open
An erasure broadcast network is considered with two disjoint sets of receivers: a set of weak receivers with all-equal erasure probabilities and equal cache sizes and a set of strong receivers with all-equal erasure probabilities and no ca…
