Helen Frankenthaler : The calculus for gender neutrality within the post abstractionist color field movement

In a decade marked by the omnipresence of black-and-white television, McCarthyism, the end of the Korean War and the fledgling sounds of rock n’ roll, the 1950s invited American artists to utilize color in forms and abstractions to challenge the domesticated, safe boundaries established by European masters. The 1950s perpetuated dominate male, decision–making stereotyping while subordinating females as submissive, adorned homemakers. Sandwiched between the creative genius and evolution of the U.S abstract expressionist movement of the 1940s and the emerging pop artists of the 1960s, the 1950s signaled the development and the ascendency of Helen Frankenthaler. As a woman artist who adapted elements of cubism into her earlier works, Frankenthaler abandoned this style in favor of abstract figurative painting that curried worldwide acceptance. As the daughter of New York Supreme Court Justice, Alfred Frankenthaler, Helen was both unapologetic and self-effacing to critics who genderized her openings and shows and attempted to marginalize her contributions to the canon of abstractionism

A Resonance Method for Measuring the Phase Difference of Condensers

It is a well-known fact that when an alternating electromotive force is impressed upon a condenser the resulting current does not lead the electromotive force by the theoretical ninety degrees. This is particularly noticeable in the case of paper condensers of the telephone type so often used in laboratories for the study of the alternating current circuit. When an attempt is made to interpret such experiments by graphic methods it is sometimes found that the power factor of the condensers is so great that it must be taken into account. The power factor angle or the angle by which the current lags behind the theoretical ninety degree lead is known as the phase difference of the condenser

An Interesting Case of Resonance in an Alternating Current Circuit

The phenomena of voltage and current resonance are familiar to all students of alternating currents. The former occurs in series circuits and complete resonance is secured when the condensive reactance is equal to the inductive reactance. The latter occurs in connection with parallel circuits, the necessary condition being that the sum of all the susceptances, both condensive and inductive, equals zero

Scenery Picture Memory Test: A new type of quick and effective screening test to detect early stage Alzheimer's disease patients

It is highly desirable to develop a neuropsychological screening test which is sensitive to the early stage of Alzheimer's disease (AD), and is easy to administer at the primary care physician's (PCP's) office.Participants were 128 AD patients and 54 healthy volunteers. Brief cognitive screening tests were administered to the participants including the Mini-Mental State Examination (MMSE), Clock Drawing Test (CDT), Verbal Fluency Test (VFT), a Verbal Category Cued Memory test (CCMT) and the Scenery Picture Memory Test (SPMT). In the SPMT, a scenery picture of a living room containing 23 familiar objects was used. The administration of the SPMT comprised the first shallow memory session (Pict 1) and the second deep memory session (Pict 2). The area under the receiver–operator curve (AUC) was used to compare the efficacy of SPMT with other cognitive tests.Pict 1, which requires less than 2 min to complete, had the same AUC as Pict 2, and showed significantly larger AUC than MMSE, CDT and VFT for all (MMSE 19–23) and very mild (MMSE ≥ 24) AD patients. When we conducted the similar analysis separately for those younger than 75 years and those aged 75 years or older, we obtained the same results as above among the older age group. Pict 1 showed larger AUC than CCMT in overall sample and also in the older age group, although the difference was not statistically significant.The SPMT could be useful for detection of mild and very mild AD in settings even where time is limited.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/78663/1/j.1447-0594.2009.00576.x.pd

MC-ViViT: Multi-branch Classifier-ViViT to Detect Mild Cognitive Impairment in Older Adults using Facial Videos

Deep machine learning models including Convolutional Neural Networks (CNN) have been successful in the detection of Mild Cognitive Impairment (MCI) using medical images, questionnaires, and videos. This paper proposes a novel Multi-branch Classifier-Video Vision Transformer (MC-ViViT) model to distinguish MCI from those with normal cognition by analyzing facial features. The data comes from the I-CONECT, a behavioral intervention trial aimed at improving cognitive function by providing frequent video chats. MC-ViViT extracts spatiotemporal features of videos in one branch and augments representations by the MC module. The I-CONECT dataset is challenging as the dataset is imbalanced containing Hard-Easy and Positive-Negative samples, which impedes the performance of MC-ViViT. We propose a loss function for Hard-Easy and Positive-Negative Samples (HP Loss) by combining Focal loss and AD-CORRE loss to address the imbalanced problem. Our experimental results on the I-CONECT dataset show the great potential of MC-ViViT in predicting MCI with a high accuracy of 90.63\% accuracy on some of the interview videos.Comment: 12 pages, 5 tables, 5 figures, 17 equation
