Static Torsion Testing and Modeling of a Variable Thickness Hybrid Composite Bull Gear

Torsional strength of a variable thickness hybrid gear web was measured by performing static testing on the part in a large torsion test frame. The outer rim of the hybrid gear web was fixed to the bottom of the test frame and loading was applied to the web through a shaft. The test setup included the installation of digital image correlation (DIC) systems to obtain deformation and strain measurements from the surfaces of the hybrid gear web and the mechanical test equipment to ensure reliability of the test. The results indicated that the variable thickness hybrid gear web achieved approximately twice the torsional strength compared to that of previous hybrid gear designs. The DIC analysis showed significantly more straining of the loading shaft than the actual test article. Additionally, the results demonstrated the importance and affect that the metallic, lobed interlock features had on the principal strain and out-of-plane displacement fields. The analysis revealed that the fixed outer rim was in fact rotating and a rigid body motion compensation (RBMC) function was computed to determine the actual rotation of the hub and composite web relative to the outer rim. Modeling simulations were performed for the variable thickness hybrid gear web and correlated well with the RBMC rotational deformation seen in the DIC analysis. In addition to benchmarking the load capacity of the hybrid gear web, measuring its strength is useful information to define the parameters needed for dynamic, endurance, and other testing of the part

Measuring Vibrations from Video Feeds

By using a high-speed camera, researchers at MIT in 2014 where able to recover human speech from videos of minute vibrations of objects in a room. For example, in one experiment a 2,200fps camera was positioned outside a room behind sound-proof glass, videoing an empty crisp packet on the floor inside the room, while a researcher shouted “Mary had a little lamb” at the crisp packet. By detecting minute oscillations of the crisp packet of 1 μm (0.001 mm), and using hours of computer processing, a ten second audio clip could be produced that was recognisably “Mary had a little lamb” in an American accent. The purpose of this study group was to investigate whether this tech- nique could be used in practice, with emphasis on the recovery of intel- ligible speech from a video feed of a room. During the week, the group investigated several aspects of the problem, including: • how much an object vibrates due to sound; • what can be done to maximize the vibration; • how the MIT technique detects minute vibrations in videos; • what affects the quality of the resulting recording; and • how good a recording is needed for intelligible speech. It was discovered the MIT experiments would not have recovered intel- ligible speech from an ordinary conversation; their success depended on loud sounds and prior knowledge of “Mary had a little lamb”. Camera vibrations were also ignored by MIT; these are expected to be signifi- cant, but the technique could be adapted to be resilient to them. Other possibilities for enhancing their technique, by exploiting resonances or reflections, are discussed in the report. A high-speed low-noise cam- era is essential, and any existing video footage (such as from CCTV) is unlikely to be of sufficient quality. Further experiments with high-end high-speed cameras are needed to assess the feasibility of the technique in practice

Role of the Chemokine Receptors CCR1, CCR2 and CCR4 in the Pathogenesis of Experimental Dengue Infection in Mice

Dengue virus (DENV), a mosquito-borne flavivirus, is a public health problem in many tropical countries. Recent clinical data have shown an association between levels of different chemokines in plasma and severity of dengue. We evaluated the role of CC chemokine receptors CCR1, CCR2 and CCR4 in an experimental model of DENV-2 infection in mice. Infection of mice induced evident clinical disease and tissue damage, including thrombocytopenia, hemoconcentration, lymphopenia, increased levels of transaminases and pro-inflammatory cytokines, and lethality in WT mice. Importantly, infected WT mice presented increased levels of chemokines CCL2/JE, CCL3/MIP-1α and CCL5/RANTES in spleen and liver. CCR1-/- mice had a mild phenotype with disease presentation and lethality similar to those of WT mice. In CCR2-/- mice, lethality, liver damage, levels of IL-6 and IFN-γ, and leukocyte activation were attenuated. However, thrombocytopenia, hemoconcentration and systemic TNF-α levels were similar to infected WT mice. Infection enhanced levels of CCL17/TARC, a CCR4 ligand. In CCR4-/- mice, lethality, tissue injury and systemic inflammation were markedly decreased. Despite differences in disease presentation in CCR-deficient mice, there was no significant difference in viral load. In conclusion, activation of chemokine receptors has discrete roles in the pathogenesis of dengue infection. These studies suggest that the chemokine storm that follows severe primary dengue infection associates mostly to development of disease rather than protection

Assessing the potential of acoustic telemetry to underpin the regional management of basking sharks (Cetorhinus maximus)

Acoustic telemetry can provide valuable space-use data for a range of marine species. Yet the deployment of species-specific arrays over vast areas to gather data on highly migratory vertebrates poses formidable challenges, often rendering it impractical. To address this issue, we pioneered the use of acoustic telemetry on basking sharks (Cetorhinus maximus) to test the feasibility of using broadscale, multi-project acoustic receiver arrays to track the movements of this species of high conservation concern through the coastal waters of Ireland, Northern Ireland, and Scotland. Throughout 2021 and 2022, we tagged 35 basking sharks with acoustic transmitters off the west coast of Ireland; 27 of these were detected by 96 receiver stations throughout the study area (n = 9 arrays) with up to 216 detections of an individual shark (mean = 84, s.d. 65). On average, sharks spent ~ 1 day at each acoustic array, with discrete residency periods of up to nine days. Twenty-one sharks were detected at multiple arrays with evidence of inter-annual site fidelity, with the same individuals returning to the same locations in Ireland and Scotland over 2 years. Eight pairs of sharks were detected within 24 h of each other at consecutive arrays, suggesting some level of social coordination and synchronised movement. These findings demonstrate how multi-project acoustic telemetry can support international, cost-effective monitoring of basking sharks and other highly mobile species. Decision support tools such as these can consolidate cross-border management strategies, but to achieve this goal, collaborative efforts across jurisdictions are necessary to establish the required infrastructure and secure ongoing support

Talking and Chewing Gum: Processing Real Speech Variation with the Featurally Underspecified Lexicon

The human capacity to successfully understand the wide variety of spoken language\ud encountered constantly by listeners is nothing short of astounding. Findings and theories from\ud both theoretical phonology and psycho linguistics have been brqught together in attempts to\ud explain listeners' ability to process the variation produced by real speakers of natural language.\ud This study proposes to examine one such theory, Lahiri's and Reetz' (2002) Featurally\ud Underspecified Lexicon (FUL). While FUL is supported by a great deal of theoretical and\ud experimental evidence from both phonology and psycho linguistics, it has never been tested\ud directly on the behaviour of real speakers and listeners. An analysis of data taken from\ud children's speech errors both provides support for the model and illuminates ways that FUL fails\ud to account for real human responses to variation in language

Effects of School-Based Physical Activity on Children’s Core Executive Function Abilities

Children in the United States are becoming increasingly sedentary, linked to detrimental effects on both physical and mental health. Introducing physical activity interventions in schools offers a promising approach to address this trend, while also enhancing children’s executive functioning abilities. Executive functioning abilities are crucial for social-emotional development and academic success. Therefore, the purpose of this study was to explore whether a 6-week physical activity intervention at moderate intensity was associated with increases in executive functioning among girls who are enrolled in third through fifth grade. It was hypothesized that executive functioning abilities (working memory, inhibition, and cognitive flexibility) would significantly increase among participants (n = 30) after participation in the physical activity intervention. Further, the second research question examined if changes in executve functioning abilities among elementary-aged girls who participated in a physical activity intervention would be moderated by elevated behavioral concerns. Results demonstrated improvements in the three core executive function abilities, including working memory, cognitive flexibility, and inhibition, following the intervention period as measured by pre- and post-test assessments. Behavioral concerns were measured via teacher behavioral rating forms, and were not significant in determining changes in executive functioning abilities. These findings underscore the potential of school-based physical activity interventions in promoting children’s holistic well-being. Moreover, the study utilized physical activity curriculum that is both practical and replicable for schools, emphasizing the feasibility and accessibility of such initiatives. By highlighting these benefits and considerations, this research demonstrates the importance of integrating physical activity into school settings and calls for further exploration into its broader implications and potential for future research
