Random and stock-flow models of labour market matching - Swedish evidence [PDF]

In this paper we estimate aggregate matching functions taking advantage of a rich data base that enables us to compute observations on the variables in the matching function at (virtually) any frequency to assess the importance of the time aggregation ...

Epidemiological and evolutionary outcomes in gene-for-gene and matching allele models

Frontiers in Plant Science, 2016
Gene-for-gene (GFG) and matching-allele (MA) models are qualitatively different paradigms for describing the outcome of genetic interactions between hosts and pathogens.

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

"Real Indeterminacy of Stationary Equilibria in Matching Models with Media of Exchange" [PDF]

In this paper, it is shown that real indeterminacy of stationary equilibria generically arises in most matching models with perfectly divisible media of exchange.

Wiggle-matching using known-age pine from Jermyn Street, London [PDF]

, 2009
A slice of pine from the period covered by single-year calibration data (Stuiver 1993) was selected to serve as part of the quality assurance procedures of the English Heritage radiocarbon dating program, following successful wiggle-matching of 14C ...

Match-Unity: Long-Form Text Matching With Knowledge Complementarity

IEEE Access
Semantic text matching is a fundamental task in Natural Language Processing, with existing methods mainly focusing on short texts. However, handling long texts remains a challenge, as conventional approaches often involve slicing or keyword filtering ...

Generative Lines Matching Models

CoRR
In this paper we identify the source of a singularity in the training loss of key denoising models, that causes the denoiser's predictions to collapse towards the mean of the source or target distributions. This degeneracy creates false basins of attraction, distorting the denoising trajectories and ultimately increasing the number of steps required to

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Accounting For Endogenous Search Behavior in Matching Function Estimation [PDF]

We show that equilibrium matching models imply that standard estimates of the matching function elasticities are exposed to an endogeneity bias, which arises from the search behavior of agents on either side of the market.

On the Theoretical Link between Optimized Geospatial Conflation Models for Linear Features

ISPRS International Journal of Geo-Information
Geospatial data conflation involves matching and combining two maps to create a new map. It has received increased research attention in recent years due to its wide range of applications in GIS (Geographic Information System) data production and ...
