$x-y$ swap for $(2,2p+1)$ minimal string
We continue the study of 2D gravity -- ``matrix model'' duality on the example of $(2,2p+1)$ minimal string. We propose a reformulation of the duality, related to a more conventional one by ``$x-y$ swap'' in the language of topological recursion. This formulation elucidates some conceptual and technical difficulties in the dictionary of the duality and relation to other examples. In particular, it allows to circumvent the necessity to use ``resonance transformations'', that were previously intr…

Swap Kripke models for deontic LFIs
We present a construction of nondeterministic semantics for some deontic logics based on the class of paraconsistent logics known as Logics of Formal Inconsistency (LFIs), for the first time combining swap structures and Kripke models through the novel notion of swap Kripe models. We start by making use of Nmatrices to characterize systems based on LFIs that do not satisfy axiom (cl), while turning to RNmatrices when the latter is considered in the underlying LFIs. This paper also presents, for…

Pricing and hedging the prepayment option of mortgages under stochastic housing market activity
Prepayment risk embedded in fixed-rate mortgages forms a significant fraction of a financial institution's exposure. The embedded prepayment option bears the same interest rate risk as an exotic interest rate swap with a suitable stochastic notional. Focusing on penalty-free prepayment because of the contract owner's relocation to a new house, we model the prepayment option value as an European-type interest rate receiver swaption with stochastic maturity matching the stochastic time of relocat…

SQUASH: A SWAP-Based Quantum Attack to Sabotage Hybrid Quantum Neural Networks
We propose a circuit-level attack, SQUASH, a SWAP-Based Quantum Attack to sabotage Hybrid Quantum Neural Networks (HQNNs) for classification tasks. SQUASH is executed by inserting SWAP gate(s) into the variational quantum circuit of the victim HQNN. Unlike conventional noise-based or adversarial input attacks, SQUASH directly manipulates the circuit structure, leading to qubit misalignment and disrupting quantum state evolution. This attack is highly stealthy, as it does not require access to t…

PULSE-A Mission Overview: Optical Communications for Undergraduate Students
Recent advances in the size, weight, and power (SWaP) requirements for space-based sensing have dramatically increased the demand for high-bandwidth downlink. However, high data rate RF transceivers still pose significant SWaP and cost restrictions, especially for university-class CubeSat missions. Optical communication may provide a solution to this challenge, enabling data transmission with order-of-magnitude rate increases over RF while being both secure and SWaP-efficient. The Polarization-…

Maybe some Linux Kernel expert could help me with this:
Due to the nature of my work, I regularily run a very memory intensive process and my system runs out of memory during very few peak moments.
The system can't swap out memory fast enough and freezes. If I disable swap, the process gets killed instead.
Is there any way I can keep the system responsive? Ideally, only the offending process would get slowed down, but not other applications.

SPTCStencil: Unleashing Sparse Tensor Cores for Stencil Computation via Strided Swap
Stencil computation, a pivotal numerical method in science and engineering, iteratively updates grid points using weighted neighbor contributions and exhibits strong parallelism for multi-core processors. Current optimization techniques targeting conducting stencil computation on tensor core accelerators incur substantial overheads due to redundant zero-padding during the transformation to matrix multiplication. To address this, we introduce a sparse computation paradigm that eliminates ineffic…

#ScribesAndMakers for July 3: When (and if) you procrastinate, what do you do? If you don't, what do you do to avoid it?
I'll swap right out of programming to read a book, play a video game, or watch some anime. Often got things open in other windows so it's as simple as alt-tab.
I've noticed recently I tend to do this more often when I have a hard problem to solve that I'm not 100% sure about. I definitely have cycles of better & worse motivation and I've gotten to a place where I'm pretty relaxed about it instead of feeling guilty. I work how I work, and that includes cycles of rest, and that's enough (at least, for me it has been so far, and I'm in a comfortable career, married with 2 kids).
Some projects ultimately lose steam and get abandoned, and I've learned to accept that too. I learn a lot and grow from each project, so nothing is a true waste of time, and there remains plenty of future ahead of me to achieve cool things.
The procrastination does sometimes impact my wife & kids, and that's something I do sometimes feel bad about, but I think I keep that in check well enough, and for things my wife worries about, I usually don't procrastinate those too much (used to be worse about this).
Right now I'm procrastinating a big work project by working on a hobby project instead. The work project probably won't get done by the start of the semester as a result. But as I remind myself, my work doesn't actually pay me to work during the summer, and things will be okay without the work project being finished until later.
When I want to force myself into a more productive cycle, talking to people about project details sometimes helps, as does finding some new tech I can learn about by shoehorning it into a project. Have been thinking about talking to a rubber duck, but haven't motivated myself to try that yet, and I'm not really in doldrums right now.

A Warm-start QAOA based approach using a swap-based mixer for the TSP: theoretical considerations,implementation and experiments
This paper investigates quantum heuristics based on Mixer Hamiltonians, which allow the search to be restricted to a specific subspace and enable warm-start strategies for solving the Traveling Salesman Problem (TSP). Approaches involving Mixer Hamiltonians can be integrated into the Quantum Approximate Optimization Algorithm (QAOA), where the Mixer acts as a mapping function that transforms qubit strings into feasible solution sets. We first introduce a swap-based mixer tailored to the TSP, wh…

Nothing I know of beats clubs and hams. I still keep saved searches on all the usual places, but word of mouth is the thing that always works. Almost always around here, if we put the word out that someone needs a reliable and cheap starter, someone comes up with a winner, or even a long-term loaner.
I still comb over swap meets, junk shops, wherever old electronics are piled up. My first HF radio was a dirt-filled horrowshow that cost less than a handheld but I made it work.

Acid-busting diet triggers 13-pound weight loss in just 16 weeks
Swap steaks for spinach and you might watch the scale plummet. In a 16-week crossover study, overweight adults who ditched animal products for a low-fat vegan menu saw their bodies become less acidic and dropped an average of 13 pounds—while the Mediterranean diet left weight unchanged. Researchers link the shift to lower “dietary acid load,” a hidden inflammation trigger driven by meat, eggs, and cheese.

Algorithms for variational Monte Carlo calculations of fermion PEPS in the swap gates formulation
In recent years, the variational Monte Carlo (VMC) calculations of projected entangled pair states (PEPS) has emerged as a competitive method for computing the ground states of many-body quantum systems. This method is particularly important for fermion systems where sign problems are abundant. We derive and explain the algorithms for the VMC calculations of fermion PEPS in the swap gates formulation. It is the purpose of this paper to be as concise and precise as possible.

On tests for baby universes in AdS/CFT
To address a puzzle by Antonini and Rath -- where a single CFT state has two bulk duals, one with a baby universe and one without -- Engelhardt and Gesteau recently devised a test for baby universes in AdS/CFT. Using the extrapolate dictionary, they showed that the boundary dual of a bulk swap test favored bulk spacetimes without a baby universe, providing evidence against their semiclassical validity. However, recent work suggests that holographic maps should post-select on such closed univers…

Clock Synchronization for Drone-Based Entanglement Quantum Key Distribution
Drone-based entanglement distribution provides full spatiotemporal coverage for quantum networks, enabling quantum key distribution (QKD) in dynamic environments. The security of QKD fundamentally depends on high-fidelity quantum state measurements, for which high-precision clock synchronization is indispensable, as timing jitter is inversely correlated with quantum state fidelity. However, drone-based clock synchronization is constrained by SWaP (Size, Weight, and Power) limitations and dynami…

Swapping objectives accelerates Davis-Yin splitting
In this work, we investigate the application of Davis-Yin splitting (DYS) to convex optimization problems and demonstrate that swapping the roles of the two nonsmooth convex functions can result in a faster convergence rate. Such a swap typically yields a different sequence of iterates, but its impact on convergence behavior has been largely understudied or often overlooked. We address this gap by establishing best-known convergence rates for DYS and its swapped counterpart, using the primal--d…

In this analysis we determine factors driving the cross-sectional variation in uninsured deposits during the interest rate raising cycle of 2022 to 2023. The goal of our analysis is to determine whether banks proactively managed deposit run risk prior to the hiking cycle which produced the 2023 Regional Banking Crisis.

A High-Performance Multilevel Framework for Quantum Layout Synthesis
Quantum Layout Synthesis (QLS) is a critical compilation stage that adapts quantum circuits to hardware constraints with an objective of minimizing the SWAP overhead. While heuristic tools demonstrate good efficiency, they often produce suboptimal solutions, and exact methods suffer from limited scalability. In this work, we propose ML-SABRE, a high-performance multilevel framework for QLS that improves both solution quality and compilation time through a hierarchical optimization approach. We …

Some fun facts about #Python limited API / stable ABI.
1. #CPython supports "limited API". When you use it, you get extensions that are compatible with the specified CPython version and versions newer than that. To indicate this compatibility, such extensions use `.abi3.so` suffix (or equivalent) rather than the usual `.cpython-313-x86_64-linux-gnu.so` or alike.
2. The actual support is split between CPython itself and #PEP517 build systems. For example, if you use #setuptools and specify `py_limited_api=` argument to the extension, setuptools will pass appropriate C compiler flags and swap extension suffix. There's a similar support in #meson, and probably other build systems.
3. Except that CPython freethreading builds don't support stable ABI right now, so building with "limited API" triggers an explicit error from the headers. Setuptools have opted for building explicit about this: it emits an error if you try to use `py_limited_api` on a freethreading interpreter. Meson currently just gives the compile error. This implies that package authors need to actively special-case freethreading builds and enable "limited API" conditionally.
4. A some future versions of CPython will support "limited API" in freethreading builds. I haven't been following the discussions closely, but I suspect that it will only be possible when you target that version or newer. So I guess people will need to be building two stable ABI wheels for a time — one targeting older Python versions, and one targeting newer versions plus freethreading. On top of that, all these projects will need to update their "no 'limited API' on freethreading" conditions.
5. And then there's #PyPy. PyPy does not feature a stable ABI, but it allows you to build extensions using "limited API". So setuptools and meson just detect that there is no `.abi3.so` on PyPy, and use regular suffix for the extensions built with "limited API".
