1. Polynomial computational complexity of matrix elements of finite-rank-generated single-particle operators in products of finite bosonic states 

   Ivanov, Dmitri A. (2024)

   SCIPOST PHYSICS CORE

   It is known that computing the permanent of the matrix 1 + A, where A is a finite-rank matrix, requires a number of operations polynomial in the matrix size. Motivated by the boson-sampling proposal of restricted quantum computation, I extend this result to a generalization of the matrix permanent: An expectation value in a product of a large number of identical bosonic states with a bounded number of bosons. This result complements earlier ...

2. Comparative analysis of late gadolinium enhancement assessment techniques for monitoring fibrotic changes in myocarditis follow-up 

   Karolyi, Mihaly; Polacin, Malgorzata; Kolossvary, Marton; et al. (2024)

   European Radiology

   Objectives To compare the repeatability and interrelation of various late gadolinium enhancement (LGE) assessment techniques for monitoring fibrotic changes in myocarditis follow-up. Materials and methods LGE extent change between baseline and 3-month cardiovascular magnetic resonance (CMR) was compared in patients with acute myocarditis using the full width at half maximum (FWHM), gray-scale thresholds at 5 and 6 standard deviations (SD5 ...

3. Long-term effects of elevated CO₂ on the nutrition provided to parasitoids by their herbivorous hosts 

   Najar-Rodriguez, Adriana Jeannette; Lacorazza, Sara; Klaiber, Jeannine; et al. (2024)

   Physiological entomology : from biochemistry to behaviour

   Elevated concentrations of atmospheric carbon dioxide (CO2), a consequence of anthropogenic global change, may profoundly interfere with natural ecological processes, perhaps even interactions across trophic levels. Even the survival prospects of organisms at higher trophic levels could be affected, as follows. We showed previously that the endoparasitoid Diaeretiella rapae, a specialized parasitoid of the cabbage aphid Brevicoryne ...

4. Doing good while making profits: A typology of business models for social ventures 

   De Cuyper, Lien; Clarysse, Bart; Wright, Mike (2024)

   STRATEGIC ENTREPRENEURSHIP JOURNAL

   Research SummaryBuilding on business model research and the social entrepreneurship literature, we conceptually develop a set of business model choices for social ventures. These choices specify the scope of venture beneficiaries, the extent that customers and beneficiaries overlap, and how social meaning is attached to the venture's value proposition. Concurrent configurations of these choices give rise to four types of social business ...

5. An Accurate and Efficient Recursive Convolution Method to Simulate Viscoacoustic and Viscoelastic Waves 

   Jin, Chao; Zhou, Bing; Greenhalgh, Stewart; et al. (2024)

   IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING

   Seismic wavefield forward modeling in anelastic (attenuating) media is a fundamental tool for both data processing and interpretation in modern seismic exploration. We propose a generalized recursive convolution (RC) formula to calculate the temporal convolutions directly, rather than solving many auxiliary partial differential equations of the memory variables when dealing with a viscoelastic medium. The new formula is obtained in terms ...
