Path Planning For Mobile Robots Based On Improved Rrt-Connect And Dwa Fusion, Yi Luo, Jia Deng

Journal of System Simulation

Abstract: To improve the efficiency and quality of dynamic path planning for mobile robots in complex environments, this paper proposed a path planning algorithm that combined an improved RRT-connect with the DWA. Two expanding random trees were introduced for alternating expansion, and a dynamically restricted sampling area was set to reduce the randomness of the sampling process while ensuring the probability completeness of the algorithm. A target bias adaptive step size strategy was employed to enhance the target orientation of the random tree expansion process. A greedy strategy was adopted to prune redundant nodes in the path and smooth the …

Phase Transitions In An Ising Model Of Agent Expectations In Financial Markets: Analytics And Numerical Results In One And Two-Dimensional Network Topologies, Marko Raseta, Steven D. Silver, Alina Bazarova

Faculty Research, Scholarly, and Creative Activity

We cite correspondences between dynamics in competitive markets and information theory in the objective of recovering signal from noisy information sequences. In financial markets, this objective has been examined as recovering signal on phase transitions between ordered and disordered states of agents in the market. These transitions have been indicated to denote critical points in time series of market price. Although there is a noteworthy background in information theory in the study of the dynamics of the Ising model in this manuscript, we pursue a different modeling approach. Whereas phase transitions in a multicomponent model of market states have previously …

The Theoretical Investigation Of The Stability And The Racemization Of Pristine, Functionalized, And Doped Expanded Helicenes, Bedi̇rhan Öztürk, Berkay Sütay

Turkish Journal of Chemistry

The Hückel aromatic and Möbius aromatic compounds, consisting of topologically different arrangements of adjacent benzene rings in the polycyclic aromatic hydrocarbon (PAH) family, have long attracted interest in both synthesis and theoretical chemistry. Among these, [n]-azene and [n]-circulene derivatives are more thoroughly explored due to their simple architectures and more accessible synthesis pathways. However, there are active ongoing studies on the synthesis of both [n]-helicene and expanded [n]-helicene structures, as well as Möbius circulenes, which are Möbius isomers of [n]-circulenes. In this regard, there is limited information available on both the experimental and theoretical characterization of the synthesized molecules. In …

Examining Children’S Intuitive Understanding Of Mechanical Systems With A Gears Assembly Task, Nicole Taboada

Theses

Children’s causal reasoning about machines and their components is crucial for acquiring knowledge about science and math. Mechanistic understanding involves knowing how parts can be effectively connected to work together as a functional mechanical system. Little is known about how children’s understanding of mechanical systems develops across the lifespan. Legare and Lombrozo (2014) developed a gears assembly task to assess children’s understanding and learning of mechanics but did not track this skill across ages. The present study adapted the gears assembly task to measure mechanistic understanding in children between the ages of 4 to 11 years and adults. The goal …

The Symbiotic Harm Of A Criminal Record, Ericka B. Adams, Elsa Y. Chen, Sarah E. Lageson

Faculty Research, Scholarly, and Creative Activity

Having a criminal record significantly alters a person’s life chances, decreasing their opportunities for employment, housing, student loans, voting, public benefits, and more. The collateral consequences of criminal convictions, or the civil restrictions that follow criminal convictions, are well documented. However, because individuals are connected to families and communities, it is impossible to isolate the effects of punishment to only the persons holding criminal records. Instead, the effects of criminal records might be best understood as a set of symbiotic harms, marked by relational and interdependent effects. Drawing on semi-structured interviews with 59 expungement-eligible persons and 69 community representatives, this …

Association Between Fall Risk And Orthostatic Hypotension In The Elderly In A Skilled Nursing Facility, Pramod Srikant Kshirasagar

Doctorate in Kinesiology

Background: Orthostatic hypotension (OH) is an underrecognized contributor to falls among older adults, particularly in skilled nursing facilities (SNFs) where frailty, multimorbidity, and polypharmacy is common. Methods: Thirty-three SNF residents aged ≥65 years completed orthostatic testing after five minutes supine and at one and three minutes of standing. Fall and injury histories were extracted from records and resident reports. Analyses included nonparametric tests, logistic regression, receiver operating characteristic (ROC) analysis, and exploratory qualitative coding of injury descriptions. Results: Systolic and diastolic blood pressures decreased significantly from supine to standing (both p < .001). OH was more prevalent among fallers than non-fallers (96% vs 40%; χ2(1) = 12.68, p = .007). In logistic regression with OH as the outcome, fall history was strongly associated with OH (OR = 27.0, 95% CI [3.67–198.69], p = .001); ROC analysis showed excellent discrimination (AUC = 0.84, p = .029). The most frequently coded injuries were hip and femur fractures, followed by skin tears, head injuries, and humeral fractures (exploratory). Conclusions: OH is strongly linked to falls among SNF residents. Serial measurements at 1 and 3 minutes improved detection, supporting routine OH screening in fall risk assessment and proactive interventions (e.g., medication review, activity scheduling, and environmental safety).

Biallelic Loss-Of-Function Variants In C19orf44 Lead To Retinal Degeneration, Hafiz Muhammad Jafar Hussain, Wang Meng, Yumei Li, Sabika Firasat, Mark E Pennesi, Michael B Gorin, Bin Guan, Rebecca Lynn Clark, Emma Fale-Olsen, Ranya Al Rawi, Aime Agather, Laryssa A Huryn, Paul Yang, Anna Matynia, Rui Chen

Background: Inherited retinal diseases (IRDs) are a group of disorders often resulting in progressive vision loss, ultimately leading to blindness. A significant portion of their genetic causes remain unresolved, partly due to undiscovered disease-associated genes or variants. This study aimed to identify novel genetic links to IRDs.

Methods: All patients underwent comprehensive ophthalmological evaluation, including retinal imaging (fundus autofluorescence and macular optical coherence tomography) and electroretinogram testing. Whole exome sequencing and whole genome sequencing were performed on patients with clinically unsolved IRD, and data were analysed using an in-house pipeline to identify causal variants. Subsequently, Sanger sequencing was performed to …

Genetic Influences For Distinct Impulsivity Domains Are Differentially Associated With Early Substance Use Initiation: Results From The Abcd Study, Ethan Kinstler, Aaron J Gorelik, Sarah E Paul, Adamya Aggarwal, Emma C Johnson, Melissa A Cyders, Arpana Agrawal, Ryan Bogdan, Alex P Miller

2020-Current year OA Pubs

BACKGROUND: Impulsivity is among the strongest correlates of substance involvement (i.e. a broad continuum of substance-related behaviors), and distinct domains (e.g. sensation seeking [SS] and urgency) are differentially correlated, phenotypically and genetically, with unique substance involvement stages. Examining whether polygenic influences for distinct impulsivity domains are differentially predictive of early substance use initiation - a major risk factor for later problematic use - may improve our understanding of the role of impulsivity in addiction etiology.

METHODS: Data collected from participants of genetically inferred European ancestry enrolled in the Adolescent Brain Cognitive Development Study

RESULTS: SS-PGS was significantly associated with any …

The Big Bang Theory’S Blurred (Tele)Vision Of Scientific Ethics: Some Thoughts For Educators Who Want To Change The Channel, Lee-Anne Broadhead, Sean J. Howard

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

This article investigates the way the popular American television program The Big Bang Theory represents the pursuit of scientific knowledge and reflects on the cultural and educational implications of the show’s contradictory problematization and valorization of the reductionist method at the core of modern Eurocentric science. Drawing on story-lines relating to military research, animal experimentation, and pharmaceutical drug trials, we consider the show’s precarious balance of implicit critique (the consistent exposé of systematically violent, often unethical research) and overt celebration (the presentation of science as “cool,” and its practitioners as flawed but endearing). This tension, we argue, enhances the show’s …
