DeorphaNN: Virtual screening of GPCR peptide agonists using AlphaFold-predicted active-state complexes and deep learning embeddings
Results We leveraged a previously published dataset that employed a high-throughput Chinese hamster ovary (CHO) Gα16-mediated calcium signaling assay to screen peptide agonist activity across 161 putative peptide-activated GPCRs from C.
Solid neon as a noise-resilient host for electron qubits above 100 mK
Abstract Solid neon can be used as a solid host for single-electron qubits. At temperatures of around 10 mK, electron-on-solid-neon charge qubits exhibit long coherence times and high operation fidelities. However, a systematic characterization of the noise features of such systems is needed for the development of scalable quantum information architectures. Here we show that solid neon can be used as a noise-resilient host for electron qubits above 100 mK.

DeorphaNN: Virtual screening of GPCR peptide agonists using AlphaFold-predicted active-state complexes and deep learning embeddings
Abstract Peptide-activated G protein-coupled receptors (GPCRs) regulate critical physiological processes such as metabolism, neural signalling, and endocrine function through their interaction with neuropeptides and peptide hormones. Despite their importance, identifying endogenous peptide agonists for GPCRs remains challenging, particularly for orphan receptors without known ligands.
Synthetic High Angular Momentum Spin Dynamics in a Microwave Oscillator
Spins and oscillators are foundational to much of physics and applied sciences. For quantum information, a spin exemplifies the most basic unit, a qubit. High angular momentum spins (HAMSs) and harmonic oscillators provide multilevel manifolds which have the potential for hardware-efficient protected encodings of quantum information and simulation of many-body quantum systems. In this work, we demonstrate a new quantum control protocol that conceptually merges these disparate hardware platforms.
Mimic Non-Newtonian Shear-Thinning Behaviors of Blood Using Synthetic Analogs Under Various Thermal Conditions
You are already at the latest version Blood analogs are widely employed in in-vitro experiments such as particle image velocity (PIV) to study hemodynamics, assisting pathophysiological diagnosis of neurovascular and cardiovascular diseases, as well as pre-surgical planning and intraoperative orientation. To obtain accurate physical parameters critical for diagnosis and treatment, blood analogs should exhibit realistic non-Newtonian shear-thinning features.
DeorphaNN: Virtual screening of GPCR peptide agonists using AlphaFold-predicted active state complexes and deep learning embeddings
Abstract G protein-coupled receptors (GPCRs) are important cell surface receptors involved in numerous physiological processes. Although peptides are the cognate ligands for many of these receptors, identifying endogenous peptide agonists for GPCRs remains a significant challenge.
Merging the Powers of Blockchain and Artificial Intelligence
In an era of digitalization, two technologies are making profound impacts across varied industries - Blockchain and Artificial Intelligence (AI). They independently offer numerous advantages, but when interwoven, they reveal unprecedented potential, opening a panorama of possibilities that could revolutionize the way we perceive and interact with data and automated processes.
Geopolitics, the World Order, and the Economy
Historical Incentives Recent media coverage makes it hard to ignore the turbulent circumstances in and surrounding Taiwan. More formally known as the Republic of China, it is a distant memory of the bloody Chinese Civil War, and a reminder of what can happen when a country becomes divided. However, currently, Taiwan is under new pressure, not just from China, but also from the US. Taiwan's sovereignty is being threatened, and the likelihood of a Chinese invasion of Taiwan is imminent.
Does Colonialism Make Its Mother Country Poorer?
The British Empire is infamous for various reasons, whether for being the largest empire to ever exist in history, its technological advancement, its mass colonization, or others. While it is important to recognize the detrimental effect of British colonialism on its respective colonies, in this article, the focus will shift to how the echoes of British colonialism still affect the UK's economy today.
Observation of Wave-Packet Branching through an Engineered Conical Intersection
Abstract Analog quantum simulators, which efficiently represent model systems, have the potential to provide new insight toward naturally occurring phenomena beyond the capabilities of classical computers. Incorporating dissipation as a resource unlocks a wider range of out-of-equilibrium processes such as chemical reactions. Here, we operate a hybrid qubit-oscillator circuit quantum electrodynamics simulator and model nonadiabatic molecular dynamics through a conical intersection.
Why it's a Dying Industry
In 2016, 20.23 million Americans went skiing. Within five years, this figure fell by over 2 million people, with only 18.11 million Americans skiing in 2021. With this massive drop, one has to wonder what is the cause of this decline. Before diving into this question, let's look at the history of skiing. Skiing has been around since the stone age, and archaeologists have found evidence of skis dating back to around 8000 to 7000 BCE.
Drive-induced nonlinearities of cavity modes coupled to a transmon ancilla
Abstract High-Q microwave cavity modes coupled to transmon ancillas provide a hardware-efficient platform for quantum computing. Due to their coupling, the cavity modes inherit finite nonlinearity from the transmons.
Efficient Multiphoton Sampling of Molecular Vibronic Spectra on a Superconducting Bosonic Processor
Abstract The efficient simulation of quantum systems is a primary motivating factor for developing controllable quantum machines. For addressing systems with underlying bosonic structure, it is advantageous to utilize a naturally bosonic platform. Optical photons passing through linear networks may be configured to perform quantum simulation tasks, but the efficient preparation and detection of multiphoton quantum states of light in linear optical systems are challenging.
Continuous Peripheral Nerve Blocks Are Associated With Increased Rates of Emergency Department Visits After Arthroscopic Rotator Cuff Repair Surgery
The purpose of this study was to assess trends in the use of perioperative single and continuous peripheral nerve blocks (PNBs) and their associations with emergency department (ED) visits after arthroscopic rotator cuff repair (RCR) surgery. The authors used a large database from a private insurer to identify patients who received perioperative PNBs for arthroscopic RCR surgeries from 2007 to 2015. They analyzed patient demographics as well as trends in perioperative PNB use.
Four Real-Life Christmas Scrooges
Ebenezer Scrooge is the focal character of A Christmas Carol by Charles Dickens. At the beginning of the novella, Scrooge is a cold-hearted miser who despises Christmas. Scrooge’s catchphrase, “Bah, humbug!” is often used to express disgust with many of the modern Christmas traditions.
Characteristics of Current-Feedback Op-Amps: Benefits of CFA Design vs. VFAs
In this article, we’ll take a more detailed look at the functionality and characteristics of current-feedback amplifiers (CFAs). A current-feedback amplifier is a form of op-amp which most commonly serves as the error amplifier of a negative-feedback circuit where the input error is a current. In this article, we'll talk about the step responses, slew rates, input buffers of CFAs. CFA Series This article is part of a series.
Deterministic teleportation of a quantum gate between two logical qubits
For each panel, we plot the process matrix in the Pauli transfer representation (bottom) and a reconstructed state represented in the Pauli basis (top). For the reconstructed state, we choose the input state \((| 0\rangle +| 1\rangle )| 0\rangle /\sqrt{2}\), which should result in the Bell state \(| {\Phi }^{+}\rangle =(| 00\rangle +| 11\rangle )/\sqrt{2}\) when the CNOT gate is applied.

Zen and the Art of Japanese Tea Robots
In Japan, tea ceremony (cha-dou) is revered as a way to a gain deeper insights into life and philosophy. Traditional Japanese tea ceremony practitioners put in long hours to master the intricacies and details of pouring tea. The road to becoming a tea master is crucial as it develops the practitioner’s mental state as well as physical technique. However if you don’t have time to master the “way of tea”, then you can build a bot and automate your zen experience.
The IoT (Internet of Teeth)
Get ready for another step towards our dystopian future as scientists have invented a way to track and monitor what we eat. This 2mm x 2mm wireless sensor can be mounted on to teeth and can track everything that goes into your mouth. Currently it can monitor salt, glucose, and alcohol intake. The sensor then communicates wirelessly to a mobile device that tracks the data. Future revisions are predicted to monitor a wide range of nutrients and chemicals that can get ingested.
Build Your Own Antenna for Outdoor Monitoring with LoRa
LoRa and LPWANs (Low Power Wide Area Networks) are all the range (tee-hee!) in wireless these days. LoRa is a sub 1-GHz wireless technology using sophisticated signal processing and modulation techniques to achieve long-range communications. With that simplified introduction, [Omkar Joglekar] designed his own LoRa node used for outdoor sensor monitoring based on the HopeRF RFM95 LoRa module.
You Bring It, This Blings It: Retrofitting a Hot Foil Stamping Machine
Hot foil stamping is a method often used to embellish and emboss premium print media. It’s used on things like letterhead and wedding invitations to add a touch of luxury. The operation is actually quite simple, where a custom die is heated, pressed into a heat transfer foil, and then transferred on to the print media. Some of the very first manuscripts used gold leaf embossing to decorate intricate calligraphy. You can also see it often used to decorate the sides of religious texts.

EXHIBIT REVIEW: Art of the Internet scam
While waiting for the train back to Boston last Thanksgiving, I was approached by a fellow traveler with a tragic story. He had lost his wallet through a recently-discovered hole in his pocket. Now he was stranded in the station with nothing. Would I be able to spare anything? Sure, no problem. I had $5. I would be glad to help out. Sitting on the train a few minutes later, I was kicking myself. Why did I fall for such an obvious scam? How could I have been so gullible?
