Binary to binary coded decimal converter [PDF]

open access: yes, 1978
A binary coded input signal is converted to a binary coded decimal signal having N decades by employing N four bit shift registers. The bits of the input signal are sequentially supplied, in order, to the least significant position of the register for ...

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

open access: yesThe Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Mathematical modeling of the spread of the coronavirus under strict social restrictions

open access: yesMathematical Methods in the Applied Sciences, EarlyView., 2021
We formulate a simple susceptible‐infectious‐recovery (SIR) model to describe the spread of the coronavirus under strict social restrictions. The transmission rate in this model is exponentially decreasing with time. We find a formula for basic reproduction function and estimate the maximum number of daily infected individuals.

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Improvements in the computation of ideal class groups of imaginary quadratic number fields [PDF]

open access: yes, 2012
We investigate improvements to the algorithm for the computation of ideal class groups described by Jacobson in the imaginary quadratic case. These improvements rely on the large prime strategy and a new method for performing the linear algebra phase. We

Board Gender Diversity and Environmental Credit Risk in Banking: A Global Study of Bank Governance

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study investigates the relationship between board gender diversity and environmental credit risk in the global banking sector. Using a panel dataset of 345 publicly listed banks from 75 countries over the period 2018–2022, we find that greater female representation on bank boards is significantly associated with lower environmental credit

Design of experiments‐guided membrane capture facilitates integration of continuous virus inactivation using Phi6 as a surrogate virus in an intensified downstream process

open access: yesBiotechnology Progress, EarlyView.
Abstract The growing demand for cost‐efficient and flexible biomanufacturing has increased interest in process‐intensified downstream platforms. This study evaluates an intensified monoclonal antibody (mAb) purification sequence, where two unit operations traditionally performed in batch mode—Protein A capture and low pH virus inactivation (VI)—are ...
