A Mayfly-Based Approach for CMOS Inverter Design with Symmetrical Switching

open access: yesAlgorithms, 2023
This paper presents a novel approach to designing a CMOS inverter using the Mayfly Optimization Algorithm (MA). The MA is utilized in this paper to obtain symmetrical switching of the inverter, which is crucial in many digital electronic circuits. The MA

Exploring possible risk factors for time to first fall and 6-month fall incidence in persons with acute stroke

open access: yesSAGE Open Medicine, 2022
Objectives: The aim was to explore how the time to the first fall and 6-month fall incidence relates to rapidly and easily collected data in persons with acute stroke. Methods: Out of consecutively admitted patients with stroke at three stroke units, 284

Cognitive and Motor Cortical Activity During Cognitively Demanding Stepping Tasks in Older People at Low and High Risk of Falling

open access: yesFrontiers in Medicine, 2021
Background: Choice stepping reaction time tasks are underpinned by neuropsychological, sensorimotor, and balance systems and therefore offer good indices of fall risk and physical and cognitive frailty.

Safety Against Fall Every time (SAFE) (Fall prevention Campaign)

open access: yesWorld Journal of Advanced Research and Reviews, 2023
Falls are the second-leading cause of unintentional injuries or deaths worldwide. Inpatient falls result in significant physical and economic burdens for patients as well as for medical organizations. From January to November 2022, the number of fall incidents was 25. The causes identified were ineffective PFE, no hourly rounds, especially during night

Evolution of Primordial Protostellar Clouds --- Quasi-Static Analysis --- [PDF]

open access: yes, 1998
The contraction processes of metal-free molecular clouds of starlike mass (or cloud cores) are investigated. We calculate radiative transfer of the H_2 lines and examine quasi-static contraction with radiative cooling. Comparing two time-scales, the free-

Precise timing when hitting falling balls [PDF]

open access: yesFrontiers in Human Neuroscience, 2014
People are extremely good at hitting falling balls with a baseball bat. Despite the ball's constant acceleration, they have been reported to time hits with a standard deviation of only about 7 ms. To examine how people achieve such precision, we compared performance when there were no added restrictions, with performance when looking with one eye, when

Thermal Green Functions in Coordinate Space for Massless Particles of any Spin [PDF]

open access: yes, 2000
The thermal Wightman functions for free, massless particles of spin 0, 1/2, 1, 3/2, and 2 are computed directly in coordinate space by solving the appropriate differential equation and imposing the Kubo-Martin-Schwinger condition. The solutions are valid

Theories of the End of the Novel

open access: yesSelçuk Üniversitesi Edebiyat Fakültesi Dergisi, 2018
Compared to the other literary genres, the novel is the most recent form that emerged, for example, in English Literature with the rise of the bourgeoisie in the late eighteenth century. It was the work of Defoe, Richardson and Fielding in England in the
