Surveyor and analyst biases in forest density estimation from United States Public Land Surveys

Ecosphere, Volume 14, Issue 8, August 2023., 2023
Abstract Accurate forest density estimates based on United States Public Land Surveys have long been questioned because of doubts about randomness of both the surveyors' selection of witness trees and the underlying tree dispersion. This study analyzes the surveyor sampling of witness trees in six Midwestern states in the mid‐1800s.

Boosted backtracking search optimization with information exchange for photovoltaic system evaluation

Energy Science &Engineering, Volume 11, Issue 1, Page 267-298, January 2023., 2023
(1) An improved backtracking search algorithm with teaching and learning‐based optimization (TLBOBSA) is proposed to extract parameters of the photovoltaic system. (2) The performance of TLBOBSA is compared with some well‐known competitive algorithms. (3) TLBOBSA was evaluated under different irradiance levels and temperature levels.

Bit‐Sliced Implementation of SM4 and New Performance Records

IET Information Security, Volume 2023, Issue 1, 2023., 2023
SM4 is a popular block cipher issued by the Office of State Commercial Cryptography Administration (OSCCA) of China. In this paper, we use the bit‐slicing technique that has been shown as a powerful strategy to achieve very fast software implementations of SM4. We investigate optimizations on two frontiers. First, we present a more efficient bit‐sliced

A framework for evaluating sustainable renewable energy sources under uncertain conditions: A case study

International Journal of Intelligent Systems, Volume 37, Issue 10, Page 6652-6685, October 2022., 2022
Abstract The need for energy sources in India has increased abnormally in recent years due to industrial and societal growth. To meet this demand, it was a necessary choice of renewable energy sources (RESs) as a solution to lack of nonrenewable energy sources.

Euro area banks' interest rate risk exposure to level, slope and curvature swings in the yield curve

European Financial Management, Volume 28, Issue 4, Page 883-925, September 2022., 2022
Abstract We investigate the interest rate risk exposures of euro area banks during times of crises and very low interest rates. First, we assess sensitivities of banks' stock prices to changes in the level, slope and curvature of the yield curve using the Bayesian DCC M‐GARCH model.

Volatility as a Transmitter of Systemic Risk: Is there a Structural Risk in Finance?

Risk Analysis, Volume 42, Issue 9, Page 1952-1964, September 2022., 2022
Abstract This article discusses the role of volatility in the context of systemic risk in finance. The main argument is that volatility transmits risks within the financial system and beyond, shaking the financial system and threatening in particular small or vulnerable clients (SMEs, households, and also low‐ and middle‐income countries). In addition,

Relational language influences young children’s number relation skills

Child Development, Volume 93, Issue 4, Page 956-972, July/August 2022., 2022
Abstract Relational language is thought to influence mathematical skills. This study examines the association between relational language and number relation skills—knowledge of cardinal, ordinal, and spatial principles—among 104 U.S. kindergartners (5.9 years; 44% boys; 37% White, 25% Black, 14% Asian, 24% other) in the 2017–2018 academic year ...

A Burgessian critique of nominalistic tendencies in contemporary mathematics and its historiography [PDF]

, 2012
We analyze the developments in mathematical rigor from the viewpoint of a Burgessian critique of nominalistic reconstructions. We apply such a critique to the reconstruction of infinitesimal analysis accomplished through the efforts of Cantor, Dedekind ...
