Recently, we developed a nonbuckling interconnect design that provides an effective approach to simultaneously achieving high elastic stretchability, easiness for encapsulation, and high electric performance for stretchable electronics. This paper aims to systematically study its mechanical and electric behaviors, including comparisons of the nonbuckling and buckling interconnect designs on stretchability, effects of the thickness on electric performance, and modeling and experimental investigations on the finite deformation mechanics. It is found that the results on stretchability depend on the layouts. Long straight segments and small arc radii for nonbuckling interconnects yield an enhancement of stretchability, which is much better than that of buckling designs. On the other hand, shorter straight segments or thicker interconnects are better to lower the resistances of interconnects. Therefore, optimization of the designs needs to balance the requirements of both the mechanical and electric performances. The finite deformation of interconnects during stretching is analyzed. The established analytic model is well validated by both the finite element modeling and experimental investigations. This work is key for providing the design guidelines for nonbuckling-based stretchable electronics. © 2018, Science China Press and Springer-Verlag GmbH Germany, part of Springer Nature.

A new Chinese gastrointestinal tumor visual language medical model is proposed. This model integrates text and image analysis capabilities, allowing it to simultaneously explain gastrointestinal tumor images and text. The model adopts a framework design that combines a visual transformer and a foundation language model in two parts. It enhances the abilities of feature matching and instruction learning in two stages through deep training. This method improves the model's ability to perform medical summarization and answer complex medical questions. In addition, a gastrointestinal tumor medical image dataset has been organized. It contains more than 20,000 medical images paired with corresponding text. These medical resources have been organized to facilitate comprehensive interpretation of gastrointestinal tumors, which is conducive to assisting gastrointestinal tumor detection and identification. In summary, the introduction of this model and dataset can greatly promote Chinese gastrointestinal tumor detection and recognition, and provide help for many medical workers and patients.

The measurement data of the battery obtained by the sensor will be affected by gross errors, which will reduce the estimated accuracy of State of Charge (SOC). In order to solve the above problem, this paper proposes a lithium battery SOC estimation method, CRPF -GEDC, which is based on cost reference particle filter (CRPF) combined with gross error detection and compensation. This method detects the errors in the measurement data of lithium battery real time, classifies them and estimates the true value to compensate the abnormal measurement points to improve the accuracy of state estimation. Compared with the traditional CRPF, CRPF-GEDC has a higher robustness because it does not require accurate noise statistic characteristics of noise and can handle measurement data with different types of gross errors. The experimental results show that the proposed CRPF -GEDC can effectively suppress the impact of gross errors when estimating the SOC of lithium battery.

With the rapid development of computer science and technology, Model-Based Systems engineering (MBSE) has been widely used in the field of system design and simulation, gradually replacing traditional text-based systems engineering methods. As a standard modeling language in the field of systems engineering, SysML, together with modeling tools and modeling methods, is called the three pillars of MBSE. Activity diagram is a kind of behavior diagram of SysML, and its simulation plays an important role in MBSE practice. Aiming at the problem that the activity diagram simulation capability of domestic SysML modeling software is insufficient, this paper implements the simulation function of SysML activity diagram based on the fUML specification.

Considering land use types is crucial when evaluating photovoltaic (PV) potential in a city as it enables optimal space allocation, proximity to energy demand centers, and improves energy efficiency. However, previous evaluations have overlooked urban land use types. To address this gap, this study proposes a framework utilizing remote sensing data and deep learning-based methods to achieve eight fine-granularity and three coarse-granularity land use classifications. The framework calculates the PV installation area for each land use type and evaluates their power generation potential. Case studies in two cities demonstrate that Heilbronn land is suitable for ground PV installations, and rooftop PV installations are the most productive for electricity generation in Christchurch. Finally, the uncertainty of the PV installation ratio by adopting σi and the confidence interval of potential estimation is discussed. This work experiments with the framework successfully and highlights the effects of the PV installation ratio on the power generation of each land use, providing valuable instructions for urban land utilization and PV installation. © 2024, The Authors.

Materials and methods 43 patients with intracranial micro-aneurysms were analyzed retrospectively, all patients had undergone angiography with both conventional 2D-DSA(Two-Dimensional digital Subtraction Angiography) and rotational angiography with three-dimensional reconstruction; the frequency of detection of aneurysms, depiction of aneurysm neck, radiation dose, and the dosage of contrast agent were recorded respectively. Results 55 pieces of aneurysms were detected out from the 43 cases with intracranial micro-aneurysms by 3D-RA. But only 39 cases were detected out using 2D-DSA from the 55 samples, there were significant differences with regards to detection rate (P < 0.05). There were significant differences in radiation dose and dosage of contrast agent (P < 0.05) between the two methods of using 3D-RA can improve the detection rate of micro-aneurysms, which bestows obvious advantages on displaying the shape of aneurysms, the aneurysm neck at the best angle, and the relationship with the parent artery, at the same time, the amount of contrast agent and radiation dose are reduced in 3D-RA compared to 2D-DSA.
