Food for everyone: Differential feeding habits of cryptic bat species inferred from DNA metabarcoding. [PDF]

open access: yesMol Ecol, 2021
Abstract Ecological theory postulates that niches of co‐occurring species must differ along some ecological dimensions in order to allow their stable coexistence. Yet, many biological systems challenge this competitive exclusion principle. Insectivorous bats from the Northern Hemisphere typically form local assemblages of multiple species sharing ...

Enhancing the Paddy Disease Classification by Using Cross‐Validation Strategy for Artificial Neural Network over Baseline Classifiers

open access: yesJournal of Sensors, Volume 2023, Issue 1, 2023., 2023
Pathogens, including viruses, bacteria, and fungus, are the biotic agents that cause illnesses in crops and are the major cause of yield losses of up to 16 percent in certain parts of the globe. Pathogens are the primary cause of yield losses in some parts of the world.

Laboratory Notes, Laboratory Experiences, and Conceptual Analysis: Understanding the Making of Ohm's First Law in Electricity

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 43, Issue 1, Page 7-27, March 2020., 2020
Abstract Georg Simon Ohm's work in the field of electricity led to what is now considered to be the most fundamental law of electrical circuits, Ohm's Law. Much less known is that only months earlier, Ohm had published another law—one that differed significantly from the now accepted one. The latter entailed a logarithmic relation between the length of

Left‐ and Right‐Shifted Fractional Legendre Functions with an Application for Fractional Differential Equations

open access: yesAdvances in Mathematical Physics, Volume 2020, Issue 1, 2020., 2020
Two new orthogonal functions named the left‐ and the right‐shifted fractional‐order Legendre polynomials (SFLPs) are proposed. Several useful formulas for the SFLPs are directly generalized from the classic Legendre polynomials. The left and right fractional differential expressions in Caputo sense of the SFLPs are derived.
