Nuclear detection, segmentation and morphometric profiling are essential in helping us further understand the relationship between histology and patient outcome. To drive innovation in this area, we setup a community-wide challenge using the largest available dataset of its kind to assess nuclear segmentation and cellular composition. Our challenge, named coNIC, stimulated the development of reproducible algorithms for cellular recognition with real-time result inspection on public leaderboards. We conducted an extensive post-challenge analysis based on the top-performing models using 1,658 whole-slide images of colon tissue. With around 700 million detected nuclei per model, associated features were used for dysplasia grading and survival analysis, where we demonstrated that the challenge's improvement over the previous state-of-the-art led to significant boosts in downstream performance. Our findings also suggest that eosinophils and neutrophils play an important role in the tumour microevironment. We release challenge models and WSI-level results to foster the development of further methods for biomarker discovery. © 2023, CC BY-NC-SA.

It is necessary to ensure the traction driving system can survive from fault condition when the open-circuit or short-circuit fault of power electronic device occurs. The direct torque control system of traction motor based on fault-tolerant inverter is proposed in this paper. The basic principle of three-phase-four-switch traction inverter is introduced. Moreover, the direct torque control scheme based on virtual voltage vector for traction motor is designed. Meanwhile, an improved observer of stator flux with saturation limiter is employed to restrain the integral drift. Then an approximately circular flux linkage trajectory controller is designed, and the starting excitation scheme is given. Finally, MATLAB/Simulink simulation is carried out to verify the validity and effectiveness of the proposed control strategy.

In order to promote the study of system dynamics (Sd) and multi-agent theory and its wide application in the field of renewable energy, a hybrid modeling method of Sd and Agent is proposed in this paper, which is suitable for the multi-energy collaborative management and control of regional cooling, heating and power under the background of the ubiquitous Internet of Things. Based on the detailed analysis of the lack of single modeling paradigm of system dynamics and the necessity and feasibility of mixed modeling of Sd and Agent, the basic types of hybrid modeling of Sd and Agent for regional multi-energy cooperative management and control are defined, and the application forms, simulation platforms, problems and ideas of hybrid modeling of Sd and Agent in regional multi-energy cooperative management are discussed and analyzed, which can deepen the innovative application of Sd and Agent hybrid modeling in multiple fields and assist relevant managers in scientific decision-making.

driver irregular operations have long been recognized as the main contributing factors in traffic accidents. Therefore, early and accurate identification of driver actions can help mitigate the effects of potentially unsafe driving behaviors and avoid possible accidents. This paper studies skeletonbased driver action recognition using spatial-temporal graph and genetically-weighted algorithm. We first determine the body pose of the driver by selectively sampling the informative frames in a video, which includes driver joints with high confidence scores and joints position coordinate obtained in pose estimation algorithm. Afterward, we use the skeleton-based graph in the spatial-temporal domains to estimate driver's joints position, and these dynamic skeletons of the captured poses are used as inputs to the Graph convolutional Networks (GCNs). Finally, the genetically-weighted algorithm is used to vote for the joint point with the highest score of association and significant position change, and we adopt the correlation between the sensory input and the impending driver behavior to determine the driver's detailed actions. We experiment in the Kinetics, NTUrGB+d and StateFarm datasets. The results show that our method has high accuracy and strong generalization capability.

Facing uncertain and dynamic demands over different days, logistics companies need to adopt adaptive solutions for the last-mile delivery. Meanwhile, one of the major barriers for implementing vehicle routing problem (VrP) algorithms in real world dispatching systems is the stability of delivery driver's routes and schedules. To establish a theoretically sound and practically useful solution framework, this paper aims to optimize robust and consistent space-time paths for the multi-day VrP by providing daily schedules with limited variations from the master schedule. A multi-commodity network flow-based optimization model is proposed to minimize generalized transportation costs and the daily deviation of day-dependent space-time paths among demand analysis zones. Lagrange relaxation (Lr) methods and alternating direction method of multipliers (AdMM) are used to handle complex side constraints. Experiments on illustrative networks and Beijing delivery network are developed to demonstrate the effectiveness of the proposed method.

Hygroscopic dopant in hole transport layer (HTL) is a key factor contributing to moisture-induced perovskite degradation and the resulting performance loss over time. This poses obstacles to the commercialization of perovskite solar cells (PSCs). Herein, we mixed two popular hole transport materials, i.e., [2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′-spirobifluorene] (Spiro-OMeTAd) and poly (3-hexylthiophene-2,5-diyl) (P3HT), to form a binary mixed HTL. due to the presence of hydrophobic P3HT component, the mixed HTL exhibits improved moisture resistance. In addition, P3HT demonstrates a great ability to interact with the dopants, which changes π-π packing orientation of P3HT from edge-on to face-on and improves its crystallinity, thus increasing hole mobility and hole extraction capability of the mixed HTL. As a result, PSCs equipped with the Spiro-OMeTAd/P3HT mixed HTL exhibit a champion power conversion efficiency (PCE) up to 24.3% and superior operational stability. The cells without encapsulation can maintain 90% initial efficiency after storage in dark ambient conditions (30% rH) for 1200 h. These results suggest that constructing Spiro-OMeTAd/P3HT mixed HTL is a promising strategy to meet the future photovoltaic applications demands with low-cost as well as excellent efficiency and device stability.

In order to explore the effects of SnO2 content on the properties and microstructure of Ag/SnO2 electric contact materials with low silver content. A series of Ag/SnO2 electric contact materials with different SnO2 content were prepared and their arc erosion properties and physical properties were tested. The results show that with the decrease of Ag content, the hardness of Ag/SnO2 contact materials increases, and the conductivity and density decrease. When the Ag content is 88%, Ag and SnO2 enrichment zones are formed on the surface of the Ag/SnO2 contact material after arc erosion test. When the silver content is less than 82%, the surface microstructure of the Ag/SnO2 contact material after arc erosion is uniform, and no obvious Ag and SnO2 enrichment zones were formed, but cracks and pores increased.

Nitric oxide（NO） donors are versatile tools for nitric oxide biology. The biological response of NO is dependent on the transient concentration and the sustained duration. N-Nitrosated rhodamines are photo-triggered and photo-calibrated NO donors. We recently discovered that suppression of the dihedral angle between the N-nitroso fragment with the rhodamine scaffold facilitates NO *** by this discovery, we developed a fast-releasing NO donor （NOd575） suitable for biological applications, e.g., the pulmonary arterial smooth muscle cells（PASMCs）.
