[Retracted] A Study on the Impact of Digital Finance on Regional Productivity Growth Based on Artificial Neural Networks

open access: yesComputational Intelligence and Neuroscience, Volume 2022, Issue 1, 2022., 2022
The relationship between financial development and economic growth has become a hot topic in recent years and for China, which is undergoing financial liberalisation and policy reform, the efficiency of the use of digital finance and the deepening of the balance between quality and quantity in financial development are particularly important for ...

Utilization of Rural Resource Assets: Time‐Space Estimate on the Total Factor Productivity

open access: yesDiscrete Dynamics in Nature and Society, Volume 2022, Issue 1, 2022., 2022
The utilization efficiency of China’s rural collective resource assets has always been at a low level, and excessive energy consumption and input have become the main limiting factor, which seriously affects the overall improvement of agricultural modernization and rural people’s livelihood. In this paper, time measure and space measurement are adopted

The admission of former slaves into churches and monasteries: reaching behind the sources

open access: yesEarly Medieval Europe, Volume 29, Issue 4, Page 586-611, November 2021., 2021
Religious institutions in early medieval Europe were both recipients of former slaves and instigators of manumissions. By drawing on recent work concerning the admission of former slaves into churches and monasteries, the present paper identifies dominant strands in the historiography from Marc Bloch to the present, which are then re‐evaluated in light

ogs5py: A Python‐API for the OpenGeoSys 5 Scientific Modeling Package

open access: yesGroundwater, Volume 59, Issue 1, Page 117-122, January/February 2021., 2021
Abstract High‐performance numerical codes are an indispensable tool for hydrogeologists when modeling subsurface flow and transport systems. But as they are written in compiled languages, like C/C++ or Fortran, established software packages are rarely user‐friendly, limiting a wider adoption of such tools.

Finiteness Conditions for Strictness Analysis

open access: yesDAIMI Report Series, 1993
We give upper bounds on the number of times the fixed point operator needs to be unfolded for strictness analysis of functional languages with lists. This extends previous work both in the syntax-directed nature of the approach and in the ability to deal with Wadler's method for analysing lists. Limitations of the method are indicated.

Dynkin games in a general framework

open access: yes, 2011
We revisit the Dynkin game problem in a general framework and relax some assumptions. The payoffs and the criterion are expressed in terms of families of random variables indexed by stopping times.

Finitary spectral algebraic theories

open access: yes, 1988
The main purpose of the present paper is to prove the Representation Theorem for partially nonadic categories [9] over Set. We show that every such category satisfying the finitness condition is concretely isomorphic to a weak variety of partial algebras

Thinking of Melastomataceae: Revisiting Humboldt and Bonpland's Monographie des Melastomacées (1806–1823) from a historical perspective

open access: yesTAXON, Volume 75, Issue 3, June 2026.
Abstract During their voyage to the Americas (1799–1804), Alexander von Humboldt and Aimé Bonpland described and collected American flora, fauna, minerals and other objects. After returning to Europe, they published several works, including Monographie des Melastomacées, initiated by Bonpland to classify this complex botanical family.

Heat Acclimation with Blood Flow Restriction Improves Cognitive‐Motor Dual‐Task Ability and Neuromuscular Fatigue

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 5, May 2026.
ABSTRACT This study examined whether heat acclimation (HA), and HA with blood flow restriction (BFR) could attenuate cognition and neuromuscular function impairments in cognitive‐motor dual‐task (CMDT) during exercise‐heat stress. Twenty trained adults were randomly assigned to one of two HA protocols over six sessions (~8 days). Each session consisted

Finiteness Conditions for a Group of Finite Exponent

open access: yesJournal of Algebra, 1993
A periodic group \(G\) all of whose \(d\)-generator subgroups (for fixed \(d > 1\)) are solvable need not itself be solvable (Golod), and similarly for nilpotence. However if \(G\) is finite, then the solvability of every 2- generator subgroup entails the solvability of \(G\) (Thompson), and likewise for nilpotence.
