Strongly Universal Quantum Turing Machines and Invariance of Kolmogorov Complexity [PDF]

open access: yes, 2006
We show that there exists a universal quantum Turing machine (UQTM) that can simulate every other QTM until the other QTM has halted and then halt itself with probability one.

Artificial Intelligence‐Assisted Workflow for Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling

open access: yesAdvanced Materials, EarlyView.
AI‐Assisted Workflow for (Scanning) Transmission Electron Microscopy: From Data Analysis Automation to Materials Knowledge Unveiling. Abstract (Scanning) transmission electron microscopy ((S)TEM) has significantly advanced materials science but faces challenges in correlating precise atomic structure information with the functional properties of ...

Weak lensing and cosmology [PDF]

open access: yes, 1998
Recently, it has been shown that it is possible to reconstruct the projected mass distribution of a cluster from weak lensing provided that both the geometry of the universe and the probability distribution of galaxy redshifts are known; actually, when ...

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

open access: yesAdvanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Same but different? Measurement invariance of the PIAAC motivation-to-learn scale across key socio-demographic groups

open access: yesLarge-scale Assessments in Education, 2017
Background Data from the Programme for the International Assessment of Adult Competencies (PIAAC) revealed that countries systematically differ in their respondents’ literacy, numeracy, and problem solving in technology-rich environments skills; skill ...

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Isospin Invariance and Generalized Bose Statistics applied to Low Energy $K^{+-}K^0$ and $\pi^{+-}\pi^0$ Space Symmetries

open access: yes, 1999
The use of isospin invariance and Generalized Bose statistics shows that the Bose-Einstein correlation (BEC) of identical bosons seen in the $K^+K^+$ and $\pi^+ \pi^+$ systems can be extended to apply to $K^+ K^o$ and $\pi^+ \pi^o$ pairs when they are ...

On the existence of an invariant measure for the dynamical system generated by partial differential equation [PDF]

open access: yesAnnales Polonici Mathematici, 1983
Let \({\mathcal X}\) be the space of functions \(v: [0,1]\to {\mathbb{R}}\), \(v(0)=0\), satisfying a Lipschitz condition. The space \({\mathcal X}\) is provided with a certain topology. Consider the boundary value problem \((1)\quad u_ t=\lambda u-xu_ x\) in the domain \(t\geq 0\), \(0\leq x\leq 1\), with boundary conditions \(u(t,0)=0\) for \(t\geq 0\
