Exact Purification Rates for Alternating Qubit Measurements and Their Blind Spot at Right Angles
The usual way to quantify measurement incompatibility is noise robustness: how much noise must be mixed in before some joint measurement becomes possible. That is an extremal, worst-case quantity, computed by optimization, and it says little about what a real experiment would act...

Representing and Detecting Label Ambiguity in IMU-Based Exercise Evaluation
Home-based physiotherapy is performed without supervision, which leads to incorrect execution and motivates systems that assess movement automatically from inertial measurement units (IMUs). Such systems assign each repetition to a category, yet a relevant share of repetitions fa...

On Hyperinvariant Subspaces of Operators Containing Unilateral Shifts
Abstract The hyperinvariant subspace problem for Hilbert space operators T containing a unilateral shift is addressed. The discussion is based on a similarity model of T , which is an operator-matrix $$\widehat{T}= [T_{i,j}]_3$$ T ^ = [ T i , j ] 3 where $$T_{1,1}$$ T 1 , 1 is th...

The Navier–Stokes existence and smoothness problem asks whether smooth solutions to the three-dimensional incompressible Navier–Stokes equations exist globally in time for all smooth initial data, or whether finite-time singularities can form. This note argues that the classical...

Self-Closing Interiors: Self-Maintaining Informational Closure as a Second Genus of Dissociation
Abstract: Analytic idealism individuates minds by dissociation: a perspective with a private interior is an alter, bounded off from mind-at-large. Kastrup marks where this happens with a metabolism criterion — life is the extrinsic image of a process with an inside. This essay as...

Correlated-electron theory of triplet–triplet multiexciton states in polypentacene
We present correlated-electron calculations of optical spin-singlet and triplet-triplet multiexciton states in three- and four-unit pentacene oligomers as microscopic models for polypentacene. The calculations use the Pariser-Parr-Pople Hamiltonian, multiple-reference singles and...

Three-dimensional reconfigurable magnetic microswarms with boundary-transcending capabilities
Swarm behaviors are prevalent in nature and have inspired many engineering designs. However, achieving artificial swarms capable of reversibly migrating through fluids against gravity and transcending physical boundaries, such as solid–liquid and liquid-air interfaces, remains ch...

Localized Covariant Quantities Appear to Underlie Quantum Circuits
Although entangled state vectors cannot be fully described in terms of variables localized in space and time, any given entanglement experiment can be built from basic quantum circuit components with well-defined locations. We analyze such quantum circuits and present evidence th...

Pulsed Infrared Emission from Magnetar 4U 0142+61 Detected by JWST
Abstract We report on a JWST observation of the magnetar 4U 0142+61 on 2024 August 18 with the Near-Infrared Camera (NIRCam). NIRCam observed the magnetar for 33 minutes in timing mode, providing a time resolution of 2.5 s. In the F410M filter (pivot wavelength 4.08 μ m), we meas...

A contactless heat engine driven by nonreciprocal fluctuation-induced torques
We describe a contactless heat engine in which quantum and thermal electromagnetic fluctuations act as the working medium. The setup consists of two concentric cylinders held at different temperatures. The inner cylinder stably levitates within the outer one due to repulsive none...

Management of Acute Periodontal Conditions—The EFP S2k Level Clinical Practice Guideline
BACKGROUND: The European Federation of Periodontology (EFP) has developed Clinical Practice Guidelines (CPGs) for the treatment of periodontitis and for the management of peri-implant diseases. In accordance with the 2018 Classification, acute periodontal conditions are character...

Botswana provides a setting in which to examine pastoral power. Customary authority, Christian institutions, public-health programmes, and state law have each helped to shape the social regulation of gender and sexuality. This systematic review brings together Botswana-specific s...

Abstract Antimicrobial peptides (AMPs) are promising antibiotic alternatives, but current AI-based discovery often relies on sequence labels and lacks explicit modeling of peptide–membrane interactions. We developed Membrane-MaSIF, an MD-derived membrane surface matching model de...

This paper is archived as a speculative research work. We develop a theorem-controlled correspondence between the Scalar Fields (SF) formalism of Entanglement-Algebraic Spacetime and the free-photon sector of quantum electrodynamics. The construction begins without a photon objec...

As the population ages, frailty among older adults becomes a significant public health challenge. Conventional, long-duration exercise is often unsuited for older adults, whereas “exercise snacking”—a new, bite-sized approach to physical activity—shows great promise. However, mos...

Abstract The package rbreak implements methods for detecting structural breaks and estimating break locations for linear multiple regression models under general linear restrictions on the coefficient vector. Restrictions can be within regimes, across regimes, or both, and are su...
