Omnisurface: Common reality for intuitive human-robot collaboration

Click on the DOI link to access this article at the publishers website (may not be free).Effective communication and information projection are essential for human-robot teaming. The projection of images on non-planar surfaces using a conventional projector is challenging due to the inherent problem of distortion. The projection distortion occurs due to the variations in depth across the surface of the teaming workspace. As a result, the projected image, information, or symbols lose their original shape and create confusion during human-robot teaming. In this paper, we presented an innovative approach to perform distortion-free projections in the teaming workspace. A pre-warped image is constructed based on the surface geometry that the projector displays and accurately replicates the original projection image. Beyond the technical achievement, this research highlights the social acceptance of improved spatial augmented reality in human-robot teams. It fosters better teamwork, trust, and efficiency by enabling more intuitive and reliable interactions. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025

Click on the DOI link to access this article at the publishers website (may not be free).The purpose of this investigation was to examine muscle excitation at maximal running capacity without blood flow restriction (BFR) relative to submaximal running bouts with BFR. Fourteen college-Aged males randomly completed four, three-minute running bouts at 70, 80, and 90% of peak speed with BFR (70% BFR, 80% BFR, and 90% BFR) and without BFR at 100% of their peak speed (100% NOBFR). The surface electromyographic amplitudes of the vastus lateralis, rectus femoris, and vastus medialis muscles were assessed. Muscle excitation of the vastus lateralis was similar across most bouts; however, it was lower during the 70% BFR compared to 90% BFR (Meandiff =-4.67±-0.22%; Bayesian 95% high-density interval [HDI]:-7.07 to-2.2) and 100% NOBFR (Meandiff =-2.94±-0.27%; 95% HDI:-5.33 to-0.50) bouts. For the rectus femoris, muscle excitation largely increased across running speeds (70% BFR <80% BFR < 90% BFR; 90% BFR < 100% NOBFR). For the vastus medialis, muscle excitation was lower during the 70% BFR compared to 90% BFR (Meandiff =-8.15±-0.28%; 95% HDI:-15.3 to-0.89). Submaximal running with BFR increased muscle excitation responses for the vastus lateralis and vastus medialis, such that muscle excitation was similar to 100% BFR, despite 10-20% reductions in running speed. The rectus femoris muscle, however, was not affected by BFR during the submaximal running bouts. © 2024. Thieme

Thiophosphate compounds: Discovery of optical properties and precursors for two-dimensional materials

Thesis (M.S.)-- Wichita State University, College of Liberal Arts and Sciences, Dept. of Chemistry and BiochemistryThiophosphates are an important component in inorganic compounds for optical properties. Metal thiophosphates are composed of phosphorus-sulfur binaries with flexible structural motifs ranging from $[PS_4]^{3-}, [P_2S_6]^{4-}, [P_2S_6]^{2-}, [P_2S_7]^{4-},$ etc., with one or more metals to balance the charge. Metal thiophosphates have the potential for great nonlinear optical (NLO) properties due to high second harmonic generation (SHG) coefficients. The chemical flexibility of thiophosphates results in a noncentrosymmetric (NCS) structure while creating a great balance between NLO properties through structural distortion. A thiophosphate family consisting of $KBiP_2S6, KSbP_2S_6, and K_2BaP_2S_6$ with a parent compound of $Ba_2P_2S_6$ is presented. The three compounds show great middle-infrared (MIR) NLO properties with SHG coefficients greater than $1.8×AgGaS_2 (AGS).$ The synthesis, crystal and electronic structures, linear and nonlinear optical properties of $KBiP_2S_6, KSbP_2S_6,$ and $K_2BaP_2S_6$ are summarized in Chapter III. In addition to practical applications such as NLO materials, transition metal thiophosphates can be used as precursors to form transition metal dichalcogenides (TMDCs) such as MoS2. Conventional methods, such as epitaxial methods, are used to synthesize TMDCs that form thermodynamically stable polymorphs. These bottom-up methods are complex and expensive while also resulting in poor crystallinity in the TMDC. Top-down methods for synthesizing metastable TMDCs by mechanical exfoliation of bulk crystal produce higher quality crystals compared to bottom-up methods. Few studies of metastable polymorphs of TMDCs exist due to the challenge of their creation. The aim of using ternary transition metal thiophosphates as a precursor for TMDCs is to thermally decompose into metastable TMDC polymorphs by a simple, cost-effective, and indirect synthesis. In Chapter IV, synthesis of TMDCs by thermal decomposition (TD) of various ternary compounds and crystal growth procedures are described

Turning the page: Midwest SLPs' lived experiences providing literacy services in schools

Click on the DOI link to access this article at the publishers website (may not be free).School-based speech-language pathologists (SLPs) from four midwestern states were surveyed about their knowledge and confidence regarding literacy intervention. To obtain accounts of lived experiences, SLPs who completed the survey were invited to a follow-up interview. Fourteen SLPs completed interviews with a member of the research team via a recorded Zoom meeting. The interviews were approximately an hour long and each question was presented on a shared screen. Interview data were transcribed and then analyzed using thematic analysis. Five overarching themes emerged: (1) SLPs are responsible for language services to support student literacy; (2) barriers of time, administrator knowledge, and instructional tools that support SLP literacy instruction; (3) collaboration and training would improve confidence; (4) how multi-tiered systems of support and Title I impact SLP literacy services; and (5) the role of other team members in literacy services. Overall, SLPs know that they can play an important role in literacy assessment and intervention but are unsure of how their specific skills fit into the greater school context. Training may improve confidence in serving students with literacy needs differently from other service providers. Future work could explore partnerships between SLPs and other professionals to best serve students with literacy needs. © 2025 Thieme All rights reserved.ESEAFor SLPs in the schools, opportunities to collaborate with other professionals such as Title I teachers and other multi-tiered systems of support (MTSS) team members may provide additional support for SLPs providing literacy services. MTSS and Title I are two distinct frameworks within the public school setting. Title I is a federally supported program sponsored by the Every Student Succeeds Act (ESEA, 2015) to support economically disadvantaged students by providing funding to ensure an \u201Copportunity to receive a fair, equitable, and high-quality education, and to close educational achievement gap\u201D (National Center for Education Statistics, n.d.). One use of Title I funding is to hire additional staff. In some districts, Title I staff are part of the MTSS team, so these frameworks often merge through collaboration to support a student's literacy acquisition

Impacts of aggressive aviation fluids on physical and chemical properties of aerospace-grade fiber composites

Click on the DOI link to access this article at the publishers website (may not be free).Fiber-reinforced composites (FRCs) are crucial in the aerospace industry because of their lightweight and durable features. However, concerns exist regarding their performance when exposed to aviation fluids. This study examines how five aviation fluids-hydraulic fluid (HF), isopropyl alcohol (Iso P), dry cleaning solvent (DCS), methyl ethyl ketone (MEK), and an oil-water mixture-affect aerospace-grade carbon and glass fiber composites over 15 and 30 days. MEK caused the highest fluid absorption in both composite types, with glass fiber composites being more prone to degradation. Interlaminar shear strength analysis showed that carbon fiber composites retained better resistance to delamination when exposed to aviation fluids, with MEK causing the greatest reduction in interlaminar shear strength (ILSS). Specifically, the ILSS of carbon fiber composites decreases by about 30% in MEK, while that of glass fiber composites drops by around 45%. Dynamic mechanical analysis demonstrated notable decreases in storage modulus and glass transition temperatures, indicating significant softening of the polymer matrix. Energy dispersive spectroscopy identified fluid-specific elemental signatures at fiber-matrix interfaces, such as phosphorus and sulfur enrichment in HF-treated samples and chloride penetration in MEK-exposed specimens. The superior performance of carbon fiber composites results from better interfacial stability compared to hydroxyl-rich glass fiber surfaces, which are vulnerable to chemical attack. This research provides insights for designing more fluid-resistant composites, paving the way for safer and more durable solutions in aerospace engineering.The authors greatly acknowledge Wichita State University, National Institute for Aviation Research and Turkish Aerospace Industries \u2013 USA (TAI-USA) for the financial and technical support of the present study
