Human-robot teaming has become increasingly important with the advent of intelligent machines. Prior efforts suggest that performance, mental workload, and trust are critical elements of human-robot dynamics that can be altered by the robot’s behavior. Most prior human-robot teaming studies used behavioral analyses, but a limited number used neural markers, without the use of physical robots and complex tasks. Here we combine behavioral and EEG cortical dynamics to examine cognitive-motor processes when individuals complete a complex task under various team environments with a robot. The results revealed that altering the robot quality affected both behavioral and EEG dynamics. Task completion with an experienced robot led to greater team performance and human trust along with lower mental workload compared to an inexperienced teammate or when individuals performed alone. EEG changes suggest that different attentional processes were engaged when humans worked with the robot and performed alone, and that visual processing was more prominent when teaming with an inexperienced teammate. This work can inform human cognitive-motor processes and the design of robotic controllers in human-robot teams.

Waste heat in fiber lasers poses major challenges in frequency, power, and pointing stabilities, as well as beam quality and power scaling. Using anti-Stokes-fluorescence cooling, we developed a radiation-balanced Yb-doped silica fiber amplifier with a novel aluminophosphosilicate core-glass composition that delivers 575 mW with no net internal heat generation by amplifying a 0.9-mW seed at 1064 nm (28.0 dB of gain). With a lower seed power (0.4 mW), a radiation-balanced gain of 31.5 dB was achieved. We discuss the strategies and recent progress in silicate-glass engineering that enabled this breakthrough performance in a small-core fiber at atmospheric pressure, as well as the potential for power-scaling radiation-balanced fiber lasers to the 100-watt level through advanced fiber designs. Our findings point to a promising path for stable high-power operation free from thermal limitations. © 2025 SPIE.

Monitoring flowers over time is essential for precision robotic pollination in agriculture. To accomplish this, a continuous spatial-temporal observation of plant growth can be done using stationary RGB-D cameras. However, image registration becomes a serious challenge due to changes in the visual appearance of the plant caused by the pollination process and occlusions from growth and camera angles. Plants flower in a manner that produces distinct clusters on branches. This paper presents a method for matching flower clusters using descriptors generated from RGB-D data and considers allowing for spatial uncertainty within the cluster. The proposed approach leverages the Unscented Transform to efficiently estimate plant descriptor uncertainty tolerances, enabling a robust image-registration process despite temporal changes. The Unscented Transform is used to handle the nonlinear transformations by propagating the uncertainty of flower positions to determine the variations in the descriptor domain. A Monte Carlo simulation is used to validate the Unscented Transform results, confirming our method’s effectiveness for flower cluster matching. Therefore, it can facilitate improved robotics pollination in dynamic environments. Copyright © 2025, The Authors. All rights reserved.

We report the first-ever study on the radiation resilience of a back-end-of-line (BEOL) compatible W-doped Indium Oxide (IWO) ferroelectric field-effect transistor (FEFET) under neutron irradiation. The findings demonstrate remarkable resilience of both Hf 0.5 Zr 0.5 O 2 (HZO) ferroelectric capacitors (FECAPs) and IWO FEFETs to neutron irradiation. Subjected to neutron irradiation at fluences up to 10 15 n/cm 2 , HZO FECAPs maintain stable remnant polarization (2P r ) and coercive voltage (2V c ) up to 10 11 cycles without any breakdown. The IWO FEFETs show robust switching performance and exhibit minimal degradation in memory window (MW) and read current window (CW). Importantly, the retention and endurance performance remain stable after neutron radiation exposure, without significant failure. Destiny simulations were performed to assess the impact of radiation on the system-level performance of an 8 MB 1T-1FEFET-based embedded RAM at the 32 nm node. The results showed negligible effects on read latency and only a minor 0.36% increase in dynamic read energy at a neutron fluence of 10y15 n/cm 2 . The combination of high performance, non-volatility, and radiation hardness makes IWO FEFETs a promising candidate for high-density, persistent memory applications in radiation-rich environments.

Volumetric muscle loss (VML), a severe muscle tissue loss from trauma or surgery, results in scarring, limited regeneration, and significant fibrosis, leading to lasting reductions in muscle mass and function. A promising approach for VML recovery involves restoring vascular and neural networks at the injury site, a process not extensively studied yet. Collagen hydrogels have been investigated as scaffolds for blood vessel formation due to their biocompatibility, but reconstructing blood vessels and guiding innervation at the injury site is still difficult. In this study, collagen hydrogels with varied densities of vessel-forming cells are implanted subcutaneously in mice, generating pre-vascularized hydrogels with diverse vessel densities (0–145 numbers/mm2) within a week. These hydrogels, after being transplanted into muscle injury sites, are assessed for muscle repair capabilities. Results showed that hydrogels with high microvessel densities, filling the wound area, effectively reconnected with host vasculature and neural networks, promoting neovascularization and muscle integration, and addressing about 63% of the VML. © 2024 Wiley-VCH GmbH.

作者： Bhuiyan, A.F.M. Anhar Uddin Meng, Lingyu Yu, Dong Su Dhara, Sushovan Huang, Hsien-Lien Vangipuram, Vijay Gopal Thirupakuzi Hwang, Jinwoo Rajan, Siddharth Zhao, Hongping Department of Electrical and Computer Engineering The Ohio State University ColumbusOH43210 United States Department of Materials Science and Engineering The Ohio State University ColumbusOH43210 United States Department of Electrical and Computer Engineering University of Massachusetts Lowell LowellMA01854 United States

In this study, we investigated the electrical and structural properties of metal-oxide-semiconductor capacitors (MOSCAPs) with in-situ metal-organic chemical vapor deposition (MOCVD)-grown Al2O3 dielectrics deposited at varying temperatures on (010) β-Ga2O3 and β-(AlxGa1-x)2O3 films with different Al compositions. The Al2O3/β-Ga2O3 MOSCAPs demonstrated a significant impact of Al2O3 deposition temperature on their electrical properties as characterized by capacitance-voltage (C-V) and current-voltage (I-V) measurements. Higher deposition temperatures (900 °C) resulted in reduced voltage hysteresis (~0.3 V) and improved reverse breakdown voltage of 74.5 V with a corresponding parallel-plate electric field of EBr, Al2O3 = 5.01 MV/cm and EBr, Ga2O3 = 4.11 MV/cm under reverse bias. In contrast, lower deposition temperatures (650 °C) yielded higher voltage hysteresis (~3.44 V) and lower reverse breakdown voltage (VBr = 38.8 V with EBr, Al2O3 = 3.69 MV/cm and EBr, Ga2O3 = 2.87 MV/cm), but exhibited superior forward breakdown fields, increasing from 5.62 MV/cm at 900 °C to 7.25 MV/cm at 650 °C. High-resolution scanning transmission electron microscopy (STEM) imaging revealed a strong correlation between the deposition temperature of Al2O3 and its crystallinity. At 900 °C, Al2O3 exhibited larger crystalline regions and sharper interfaces as compared to 650 °C, contributing to improved reverse breakdown fields. For Al2O3/β-(AlxGa1-x)2O3 MOSCAPs, increasing Al composition from x = 5.5% to x = 9.2% resulted in a reduction in net carrier concentration with enhanced reverse breakdown fields, from EBr, (AlxGa1-x)2O3 = 2.55 MV/cm to 2.90 MV/cm. The reverse breakdown electric field in the Al2O3 dielectric also increased from EBr, Al2O3 = 2.41 MV/cm to 3.13 MV/cm as the Al composition increases from 5.5% to 9.2%. Forward breakdown fields of the Al2O3/β-(AlxGa1-x)2O3 MOSCAPs increased from EBr, Al2O3 = 5 MV/cm to 5.4 MV/cm with the increase of Al composition from 5.5% to 9.2%, respect

A fundamental supporting technology for wireless systems of communication is the multi-input multi-output (MIMO) antenna. In this article, we propose a newly developed quad-element MIMO antenna design for a variety of modern applications such as mobile phones, the Internet of Things (IoT), and telecommunication technologies. So, we presented the design of this antenna in two stages. The first stage was to design the antenna simulation using CST Studio Suite. The second stage is actually manufacturing the antenna. This antenna serves all sophisticated wireless technology applications since it operates at many frequencies ranging from 1 to 20 GHz. This antenna is characterized by its small size, so its dimensions are 28×28×1.6 mm3. The antenna's performance is good based on CST Studio Suite results and manufacturing in engineering laboratories since the antenna's reflection coefficients resonate at six major frequencies at 4, 8, 12, 14, 18, and 20 GHz. In addition, the isolation value between elements in the MIMO configuration is ≤ -35 dB, and the highest gain is 10 dB. While the overall efficiency is between 75% to 100%. Finally, the results indicate that the simulated antenna design matches perfectly with the real antenna manufactured due to the precision manufacturing strategy described in this article. © 2023 IEEE.
