This research aims to create a virtual reality-based practice system that simulates real-stage performance environments, assisting amateur dancers in overcoming stage fright and practicing group choreography that is difficult to achieve during individual practice. In this study, users can engage in performance simulations within the created system using the HTC VIVE virtual reality device. Within the system, we have developed a virtual stage space system that only requires a 2m x 3.5m physical area to simulate a large virtual stage experience. Users can also simulate choreographic positioning with virtual dance partners within this system, providing amateur dancers with group dance rehearsal practice opportunities that are not feasible during solo practice. Additionally, by creating three different audience modes, we aim to help users simulate various audience scenarios they may encounter during a performance. The system includes a recording feature that captures users' simulated performances, allowing them to review their actions and receive feedback after practice.

In this work, hydrothermal (HT)-synthesized gallium oxide (Ga2O3) nanorods were applied on indium tin oxide (ITO) glass substrates to create a dual-functional ph-glucose sensing device. Extended-gate field-effect transistors (EGFETs) were designed for ph and glucose sensing, and the response to ph levels ranging from 1 to 11 was tested using both chemical bath deposition (CBd) and high-pressure hydrothermal methods. Two sensor configurations, Ga2O3(CBd)/ITO/glass and Ga2O3(HT)/ITO/glass, were immersed in solution ph1 to 11 and cultured medium for hydrogen ion and glucose sensing. The results demonstrated that, for ph sensing in different samples, both IdS-VdS analysis and IdS-VGS analysis showed superior linearity and sensitivity with the HT method. For glucose detection, the HT method was selected for further experiments due to its maintained concentration-dependent relationship and selectivity towards various common sugars. When using culture medium dMEM as the sample (4.5 mg/ml glucose concentration), the accuracy of glucose estimation reached 99%. Stability and biocompatibility tests were also conducted, and the results indicated consistent performance. In summary, the HT-synthesized Ga2O3 nanorods exhibited high sensitivity, selectivity, and stability without affecting cell growth. Therefore, they hold great potential for applications not only in general blood glucose sensing but also in studying cell microenvironment metabolism. © 2023 Elsevier B.V.

Wasp communities are often complex and speciose and often associated with plant and herbivorous hosts. Nonpollinating wasps are one example of these communities: these communities can reach 20 species on a single species of Ficus trees. Such diversity implies that the number of interactions is high, and the trophic web may be complicated to disentangle. Some of wasp species may be gall wasps whereas the majority of them are parasitoid wasps feeding on other wasp species larvae. To understand the nonpollinating fig wasp community associated with Ficus subpisocarpa in Northern Taiwan, the oviposition timing of the fig wasps has been monitored and a bagging experiment has been done on several crops. Twenty-one morphospecies were found, and three fig crops type were defined by the wasp composition and fig traits as “typical” crops, “rare NPFWs” crops (RN), and “rare pollinators” (RP) crops. The diversity indexes showed that the typical type has the highest diversity and the RN type, which is the most dissimilar crop from the others, has the lowest diversity. From their oviposition time along the fig development, the nonpollinating fig wasps can be easily divided into two guilds: gall wasps and parasitoid wasps. Moreover, one of the most striking results of this study is the presence of figs that do not produce any pollinator in RP crops. The implications of this type of crops on the mutualism between Ficus subpisocarpa and its pollinator are discussed. © 2023, The Author(s), under exclusive licence to Springer Nature B.V.

To learn accurate representations of molecules, it is essential to consider both chemical and geometric features. To encode geometric information, many descriptors have been proposed in constrained circumstances for specific types of molecules and do not have the properties to be "robust": 1. Invariant to rotations and translations;2. Injective when embedding molecular structures. In this work, we propose a universal and robust directional Node Pair (dNP) descriptor based on the graph-representations of 3d molecules. Our dNP descriptor is robust compared to previous ones and can be applied to multiple molecular types. To combine the dNP descriptor and chemical features in molecules, we construct the Robust Molecular Graph Convolutional Network (RoM-GCN) which is capable to take both node and edge features into consideration when generating molecule representations. We evaluate our model on protein and small molecule datasets. Our results validate the superiority of the dNP descriptor in incorporating 3d geometric information of molecules. RoM-GCN outperforms all compared baselines. Copyright © 2023, The Authors. All rights reserved.

Prediction of ligand binding sites of proteins is a fundamental and important task for understanding the function of proteins and screening potential drugs. Most existing methods require experimentally determined protein holo-structures as input. However, such structures can be unavailable on novel or less-studied proteins. To tackle this limitation, we propose LaMPSite, which only takes protein sequences and ligand molecular graphs as input for ligand binding site predictions. The protein sequences are used to retrieve residue-level embeddings and contact maps from the pre-trained ESM-2 protein language model. The ligand molecular graphs are fed into a graph neural network to compute atom-level embeddings. Then we compute and update the protein-ligand interaction embedding based on the protein residue-level embeddings and ligand atom-level embeddings, and the geometric constraints in the inferred protein contact map and ligand distance map. A final pooling on protein-ligand interaction embedding would indicate which residues belong to the binding sites. Without any 3d coordinate information of proteins, our proposed model achieves competitive performance compared to baseline methods that require 3d protein structures when predicting binding sites. Given that less than 50% of proteins have reliable structure information in the current stage, LaMPSite will provide new opportunities for drug discovery. Copyright © 2023, The Authors.

Mycobacteria are causative agents of tuberculosis (TB), which is a global health concern. drug-resistant TB strains are rapidly emerging, thereby necessitating the urgent development of new drugs. Two-component signal transduction systems (TCSs) are signaling pathways involved in the regulation of various bacterial behaviors and responses to environmental stimuli. Applying specific inhibitors of TCSs can disrupt bacterial signaling, growth, and virulence, and can help combat drug-resistant TB. We conducted a comprehensive pharmacophore-based inhibitor screening and biochemical and biophysical examinations to identify, characterize, and validate potential inhibitors targeting the response regulators phoP and MtrA of mycobacteria. The constructed pharmacophore model phar-PR-n4 identified effective inhibitors of formation of the phoP–dNA complex: ST132 (IC50 = 29 ± 1.6 µM) and ST166 (IC50 = 18 ± 1.3 µM). ST166 (Kd = 18.4 ± 4.3 μM) and ST132 (Kd = 14.5 ± 0.1 μM) strongly targeted phoP in a slow-on, slow-off manner. The inhibitory potency and binding affinity of ST166 and ST132 for MtrAC were comparable to those of phoP. Structural analyses and molecular dynamics simulations revealed that ST166 and ST132 mainly interact with the α8-helix and C-terminal β-hairpin of phoP, with functionally essential residue hotspots for structure-based inhibitor optimization. Moreover, ST166 has in vitro antibacterial activity against Macrobacterium marinum. Thus, ST166, with its characteristic 1,2,5,6-tetrathiocane and terminal sulphonic groups, has excellent potential as a candidate for the development of novel antimicrobial agents to combat pathogenic mycobacteria. © 2024 The Authors

Understanding Server-Assisted Federated Learning in the Presence of Incomplete Client Participation

Existing works in federated learning (FL) often assume an ideal system with either full client or uniformly distributed client participation. However, in practice, it has been observed that some clients may never participate in FL training (aka incomplete client participation) due to a myriad of system heterogeneity factors. A popular approach to mitigate impacts of incomplete client participation is the server-assisted federated learning (SA-FL) framework, where the server is equipped with an auxiliary dataset. However, despite SA-FL has been empirically shown to be effective in addressing the incomplete client participation problem, there remains a lack of theoretical understanding for SA-FL. Meanwhile, the ramifications of incomplete client participation in conventional FL are also poorly understood. These theoretical gaps motivate us to rigorously investigate SA-FL. Toward this end, we first show that conventional FL is not PAC-learnable under incomplete client participation in the worst case. Then, we show that the PAC-learnability of FL with incomplete client participation can indeed be revived by SA-FL, which theoretically justifies the use of SA-FL for the first time. Lastly, to provide practical guidance for SA-FL training under incomplete client participation, we propose the SAFARI (server-assisted federated averaging) algorithm that enjoys the same linear convergence speedup guarantees as classic FL with ideal client participation assumptions, offering the first SA-FL algorithm with convergence guarantee. Extensive experiments on different datasets show SAFARI significantly improves the performance under incomplete client participation. © 2024, CC BY-NC-Nd.

Pillars of smart cities include smart environment, mobility and economy. We explore impacts on these to enhance smart cities, heading towards a smart planet. Our motivation emerges from the need to decarbonize transportation. In this context, ride-sharing companies deploy electric vehicles (EVs). These should be managed by various factors: battery demand, EV charging station location, service availability, and charging time. Ride-sharing EV s aim to maximize profits via more rides. Our paper explores game theory in AI here. We propose E-Ride-Minimax, adapting the Minimax algorithm, treating EV ride-sharing companies as players. We hypothesize one player choosing its next move via total passenger-travel distance (longer the distance, larger the profit); and another player via battery usage (ratio of total passenger-travel distance to vehicle-passenger distance: optimizing this ratio enables more travel without recharging). Experimental results reveal that rising passenger numbers yield maximum battery savings (e.g. rush hours / major events); followed by stable and falling numbers. Our findings indicate that E-Ride-Minimax can reduce battery usage in some circumstances by 64%, losing 1 % profit. This is vital, given global emphasis on climate change. It increases cost-effectiveness, consumer participation and passengers per mile; reduces energy use and greenhouse gas emissions; and thus helps decarbonize transportation.
