Abstract	PPVR is a collaboration system that supports remote piano training in a virtual reality environment with the support of synchronous and asynchronous communication, various viewpoints, and detection of finger pressure. We designed two different user interfaces for the learner and the instructor and provide different viewpoints and scaffolding tools for the learner. We also explored the usage of pressure sensing inVR to enrich the information transmission during the remote piano training. We designed a user study, but were unable to conduct it due to COVID-19.

Article: Effects of Elevated CO2 and Heat on Wheat Grain Quality

Wang, Xizi / Liu, Fulai

Plants. 2021 May 20, v. 10, no. 5

2021

Abstract	Wheat is one of the most important staple foods in temperate regions and is in increasing demand in urbanizing and industrializing countries such as China. Enhancing yield potential to meet the population explosion around the world and maintaining grain quality in wheat plants under climate change are crucial for food security and human nutrition. Global warming resulting from greenhouse effect has led to more frequent occurrence of extreme climatic events. Elevated atmospheric CO₂ concentration (eCO₂) along with rising temperature has a huge impact on ecosystems, agriculture and human health. There are numerous studies investigating the eCO₂ and heatwaves effects on wheat growth and productivity, and the mechanisms behind. This review outlines the state-of-the-art knowledge regarding the effects of eCO₂ and heat stress, individually and combined, on grain yield and grain quality in wheat crop. Strategies to enhance the resilience of wheat to future warmer and CO₂-enriched environment are discussed.

Article ; Online: The impact of the “skeleton” and “skin” for the streetscape on the walking behavior in 3D vertical cities

Abstract	To reconcile the conflict between urban population agglomeration and spatial resource constraints, some cities are continuously expanding their space to high altitudes, gradually changing human activity behavior at the same time. Most of the literature analyzing the walking environment based on a two-dimensional (2D) plane may generate a significant deviation in portraying real-world urban scenes. The paper contributes to the literature by providing the “skeleton” and “skin” measurements to portray spatial geometric structures and the elements of visual surface for streetscapes in real-world urban scenes. Furthermore, this study fills the research gap in how three dimensional (3D) vertical landscapes influence walking behaviors for commuting and noncommuting purposes. The findings reveal that the strong enclosure skeleton of the street may inhibit walking behavior by creating a sense of oppression, while green, blue, and diverse skin for the streetscapes facilitates resident participation in noncommuting walking. This paper calls on planners to create more public spaces with human-oriented size and natural landscapes beside streets to achieve a pedestrian-friendly 3D vertical city.

Abstract	The distribution of nanoparticles between aqueous and organic phases is universally considered as the starting point in predicting the fate and bioavailability of engineered nanoparticles in the environment. However, the theoretical basis for determining the distribution of nanoparticles in the immiscible water-oil system remains unclear. Here, for the first time, theoretical calculations were conducted to illustrate the underlying mechanism. It was suggested that the distribution of nanoparticles was largely controlled by the surface charge, particle size and surface hydrophobicity, and the water-oil interface was not the favorable phase for nanoparticles until a size threshold (10 nm) was met and the particle surface became amphiphilic. The theoretical results were verified by the experimental approaches of different nanoparticles distributed in the water-octanol mixture. The neutralization of a charged surface led to enhanced distribution into octanol for hydrophobic nanoparticles (e.g., aqueous C

Abstract	Active Speaker Detection (ASD) aims to identify who is speaking in each frame of a video. ASD reasons from audio and visual information from two contexts: long-term intra-speaker context and short-term inter-speaker context. Long-term intra-speaker context models the temporal dependencies of the same speaker, while short-term inter-speaker context models the interactions of speakers in the same scene. These two contexts are complementary to each other and can help infer the active speaker. Motivated by these observations, we propose LoCoNet, a simple yet effective Long-Short Context Network that models the long-term intra-speaker context and short-term inter-speaker context. We use self-attention to model long-term intra-speaker context due to its effectiveness in modeling long-range dependencies, and convolutional blocks that capture local patterns to model short-term inter-speaker context. Extensive experiments show that LoCoNet achieves state-of-the-art performance on multiple datasets, achieving an mAP of 95.2%(+1.1%) on AVA-ActiveSpeaker, 68.1%(+22%) on Columbia dataset, 97.2%(+2.8%) on Talkies dataset and 59.7%(+8.0%) on Ego4D dataset. Moreover, in challenging cases where multiple speakers are present, or face of active speaker is much smaller than other faces in the same scene, LoCoNet outperforms previous state-of-the-art methods by 3.4% on the AVA-ActiveSpeaker dataset. The code will be released at https://github.com/SJTUwxz/LoCoNet_ASD. Comment: tech report

Abstract	Most of the literature has analyzed the accessibility value of landscapes based on flat terrain. However, the spatial interactions between the built and natural environments have changed with the transformation of urbanization from horizontal to vertical development. Therefore, this paper aims to redefine the amenity value of urban landscapes in terms of accessibility and visibility, considering topographical undulations and building occlusions, and to further analyze the spatial and temporal variances and spillovers of the value of urban landscapes in a three-dimensional system. Taking the famous ‘Mountain City’ Chongqing as the case study, the findings show that the topography of the mountain largely reduces walking accessibility, resulting in the accessibility of the mountain being less attractive in the three dimensional system. The visibility of rivers and parks is affected by house occlusion and a wavy terrain, and the landscape visibility of individual houses lacks a spatial spillover effect. Theoretically, the research contributes a new vertical perspective to the value of urban landscapes within the concept of the harmonious coexistence of humans and nature and empirically provides recommendations for improving functional facilities and optimizing spatial layouts to highlight the unique charm of a three dimensional city.

Abstract	Elevated atmospheric CO₂ concentrations (e[CO₂]) have a significant impact on plant physiology, grain yield and quality and the specific response of plants to e[CO₂] is closely linked to cultivars. Here, five Chinese wheat (Triticum aestivum L.) cultivars were grown under ambient CO₂ (a[CO₂], 400 ppm) and e[CO₂] (800 ppm). CO₂ enrichment significantly increased net photosynthetic rate and water use efficiency but depressed stomatal conductance. e[CO₂] increased the carbon (C) concentration but decreased the nitrogen (N) concentration in all five cultivars, whereas the effect of e[CO₂] on grain yield was highly dependent on cultivar. Moreover, e[CO₂] caused a significant reduction in grain minerals and protein, although the magnitude of reduction was different among these cultivars. The starch concentrations in the grains and flour viscosity were not significantly affected at e[CO₂]. These findings improve our understanding of the interactive effect of CO₂ conditions and cultivars on plant performances and provide a research basis to select suitable wheat cultivars to deal with food crisis in future climate.

Abstract	Elevated CO₂ concentration (e[CO₂]) alleviates the impact of drought stress on plants where abscisic acid (ABA) is involved. To explore the mechanisms by which tomato plants respond to short-term osmotic stress, Solanum lycopersicum cv. Ailsa Craig (AC), a transgenic line overproducing ABA (sp5), and an ABA-deficient mutant (flacca) were hydroponically grown under ambient CO₂ (400 ppm) and e[CO₂] (800 ppm) and then exposed to 10% or 15% (w/v) polyethylene glycol (PEG) 6000 for 24 h before transferring to PEG-free nutrient solution for 24 h. Under non-stress condition, e[CO₂] decreased root hydraulic conductance (Kᵣₒₒₜ), which was overridden by high endogenous ABA in sp5 through increasing specific leaf area and root branching intensity. Basically, e[CO₂] improved stress resistance through enhanced water status. PEG stress decreased stomatal conductance and osmotic potential in AC but these effects were less pronounced in sp5, which exhibited a stronger osmotic adjustment (OA) and improved plant fitness. A greater flexibility of hydraulic system and a reduced sensitivity of Kᵣₒₒₜ to ABA might confer sp5 a great ability to recover from PEG stress. On the contrary, high stomatal density, size and pore aperture of flacca rendered plants suffering severe stress. Moreover, the premise that PEG stress could mimic soil water deficit was the sufficient achievement of OA. Our results indicate that e[CO₂] and high endogenous ABA level could improve osmotic stress resistance in tomato plants via osmotic and hydraulic adjustments.
