This paper introduces a novel Unscented Kalman filter (UKF) approach for the pose estimation of a cable driven parallel robot (CDPR). The filter fuses accelerometer, rate gyroscope, and winch encoder data and is compared to a dynamically-updated covariance on the forward kinematics pose estimation error. The filter is tested on experimental data collected by a six degree-of-freedom CDPR test bed as well as simulated truth data. The results show that the UKF is capable of providing similar pose estimation accuracy compared to forward kinematics alone. 

When different species mate, hybrids are often inviable, sterile, or otherwise have decreased fitness. One cause of decreased hybrid fitness is hybrid incompatibilities: harmful epistatic interactions between genes inherited from the different parent species. The most well-understood hybrid incompatibilities are noticed due to having severe effects on hybrids, such as being fatal to all hybrid males, and the genes involved are pinpointed using extensive crosses. Subtler incompatibilities can be searched for by analyzing inheritance patterns in the genomes of hybrids.

Current waste management techniques, including recycling methods, are ill-equipped to handle the enormous problem that is global plastic pollution. Poly(ethyleneterephthalate) (PET) is a common plastic pollutant whose current recycling methods are environmentally unfriendly and degrade plastic quality. In contrast, enzymatic recycling of PET is environmentally friendly and retains plastic quality. However, all known PET depolymerases are too slow to for industrial use.

The purpose of this research is to improve the fit of masks for healthcare workers. Many factors influence mask fit for the most effective virus protection, including a contour around the nose bridge, overall face shape, and appropriate facial seal performance. This study seeks to determine how these factors impact mask performance through analysis of 3D scans and mask fit data collected by the Human Dimensioning Lab in 2021. To prepare for anthropometric analysis, .obj 3D face scans were cleaned and measured using Artec software, Anthroscan, and Rhino.

Post-translational modifications (PTMs) diversify the function of proteins in cellular physiology by altering a protein’s conformation, interactions with other proteins, or stability. Abnormalities in PTM dynamics have been associated in carcinogenesis, and abnormal PTM patterns have served as hallmarks for cancer. Phosphorylation is a well-studied PTM that has been implicated in a variety of cellular signaling pathways in cancer, especially where tyrosine kinase is involved.

Abstract A Semi-Automated Approach to Quantifying Synapse Formation in Cultured Iron-Deficient Hippocampal Neurons Background: Iron plays a critical role in meeting the high energy requirements of neuron structural development, which is required for neural circuit formation and function. Iron deficiency (ID) is one of the most prevalent nutrient deficiencies worldwide. ID is common in pregnant women and children, affecting 40-50% of these populations.

First-generation college students face distinctive challenges that may magnify the impacts of their first-generation status on behavioral health outcomes. Poor sleep health is documented among college student populations; however, there is minimal research that examines the structural barriers that affect the sleep of first-generation college students as a population. The association between sleep and health outcomes, especially during this stage of adulthood, strongly suggests the importance of increased research and understanding.

Acute Graft Versus Host Disease (AGVHD) is a complication that affects nearly half of patients that undergo allogeneic stem cell transplant and is characterized by poor patient outcomes in many cases. AGVHD is caused by transplanted donor cells recognizing the host organs as foreign antigens and subsequently attacking them, usually the skin and lower gastrointestinal tract (LGI).

Protein phosphatases play an integral role in cellular senescence and have been demonstrated to facilitate malignant transformation of normal healthy cells. The protein phosphatase PP2A is a known tumor suppressor in its wild-type form. PP2A is composed of three protein chains (A, B and C). However, PP2A with missense mutations at residues 179, 183, 217, and 256 on chain A no-longer remain a tumor suppressor, and have been identified in uterine cancer.

Long term surveys demonstrate a decline in avian populations in North American ecosystems. A better understanding of avian reproductive functions, using the domestic chicken as a model organism, would help strengthen breeding programs. The germinal disc (GD) is a structure that contains the nucleus and organelles of the oocyte in the ovarian follicle. The importance of the GD in maintaining viable ovarian follicles and influencing granulosa cell proliferation and responsiveness to hormones has been established in pre-ovulatory follicles.
