In order to solve the problem of talent evaluation and information management in manufacturing enterprises, a diversified dynamic evaluation information management system for manufacturing research talents and teams is constructed. Through the clustering algorithm of scientific research results built into the IPd talent information management system, the scientific research talents in the product development process are classified into five categories: basic research, applied research, technology development, results transformation and science and technology management services. The system scores the diversity indicators of research individuals with hierarchical analysis, and the four dimensions of finance, customers, internal operation, and learning and growth with the balanced scorecard method. The system has the function of classifying the information of scientific research achievements of enterprise talents; the function of storing, managing and classifying the information of scientific research talents; and the function of retrieving the information of scientific research achievements and talents for the decision-making level. The research on the multiple dynamic evaluation and information management system of scientific research talents is useful for improving the evaluation mechanism of r&d talents and teams, scientific research achievements and talent information management in manufacturing enterprises.

We present a no-go theorem for the distinguishability between quantum random numbers (i.e., random numbers generated quantum mechanically) and pseudorandom numbers (i.e., random numbers generated algorithmically). The theorem states that one cannot distinguish these two types of random numbers if the quantum random numbers are efficiently classically simulatable and the randomness measure used for the distinction is efficiently computable. We derive this theorem using the properties of cryptographic pseudorandom number generators, which are believed to exist in the field of cryptography. Our theorem is found to be consistent with the analyses on the actual data of quantum random numbers generated by IBM Quantum and also those obtained in the Innsbruck experiment for the Bell test, where the degrees of randomness of these two set of quantum random numbers turn out to be essentially indistinguishable from those of the corresponding pseudorandom numbers. Previous observations on the algorithmic randomness of quantum random numbers are also discussed and reinterpreted in terms of our theorems and data analyses.

High power continuous-wave ytterbium-doped fiber lasers have unique advantages such as high electro-optical efficiency, excellent beam quality and good thermal management, and are widely used in industrial materials processing and scientific research. However, multi-kW $(\geqslant$ 10kW) high-power fiber lasers has encountered numerous technology challenges in double-cladding fibers. In this work, we designed and fabricated a triple-cladding ytterbium doped fiber with large core diameter by using Modified Chemical Vapor deposition (MCVd) combined with all-gas-phase doping method. An excellent laser performance could be demonstrated for such a fiber with an output power of more than 10 kW and a slope efficiency of 82%, no Transverse Mode instability (TMI) is observed. Long-term laser stability at 12 kW-level was carried out in a master oscillator power amplifier (MOPA) laser system for 500 hours with power degradation less than 1%, meanwhile a stimulated raman scattering (SrS) suppression ratio that is larger than 45dB was obtained.

Prior studies in the field of motion predictions for autonomous driving tend to focus on finding a trajectory that is close to the ground truth trajectory, which is highly biased toward straight maneuvers. Such problem formulations and imbalanced distribution of datasets, however, frequently lead to a loss of diversity and biased trajectory predictions. Therefore, they are unsuitable for real-world autonomous driving, where diverse and road-dependent multimodal trajectory predictions are critical for safety. To this end, this study proposes a novel trajectory prediction model that ensures map-adaptive diversity and accommodates geometric constraints. A two-stage trajectory prediction architecture with a novel trajectory candidate proposal module, Trajectory Prediction Attention (TPA), which is trained with Lane Loss, encourages multiple trajectories to be diversely distributed in a map-aware manner. Furthermore, the diversity of multiple trajectory predictions cannot be properly evaluated by existing metrics, and thus a novel quantitative evaluation metric, termed the minimum lane final displacement error (minLaneFdE), is also proposed to evaluate the diversity as well as the accuracy of multiple trajectory predictions. Experiments conducted on the Argoverse dataset show that the proposed method simultaneously improves the diversity and accuracy of the predicted trajectories. Copyright © 2022, The Authors.

In this study, a thermal battery is designed with vacuum insulation to improve its thermal insulation. Thermal insulation is one of the many factors that determine the stability and operation of the battery. The battery’s operating time as well as the improvement in its thermal insulation performance were analyzed. The location of the vacuum insulation was set as a variable in the analysis models. The thermal battery was subjected to unsteady heat transfer analysis until the electrolyte temperature reached 450°C. Vacuum insulation was applied to the part of the base thermal battery to fabricate three model batteries. Compared with the base model B, the operating time increased by 48% for the model BS, 76% for the model BSB, and 179% for the model BSBT. due to the large area of the side, a large amount of heat was transferred;the quantity of heat transfer was in the order B>BS>BSB>BSBT. In the model BSBT, the heat loss per unit area was reduced by 93% at the side, top, bottom compared with the base model. The results of this study will serve as basic data for the design of thermal batteries with vacuum insulation and for improvement in insulation performance. © 2021 Trans Tech Publications Ltd, Switzerland.

An enhanced electric octupole (E3) strength of 45(5) W.u. has been measured for the 3−→0+ transition in Gd150, providing direct evidence for large octupole collectivity in this nucleus. The value was determined following two sensitive experiments, to measure the mean lifetime of the Jπ=3− level and the weak E3 decay branch direct to the ground state. The systematics of the E3 strength across the Gd isotopic chain reveals that enhanced octupole collectivity is obtained for Gd150. The increasing low-lying octupole strength in the Gd isotopes is analyzed with five state-of-the-art theoretical models. It is found to be best reproduced by quasiparticle random phase approximation calculations, providing a good understanding of octupole collectivity in the rare-earth region.

The electrocatalytic activity and electronic conductivity of 2d transition metal chalcogenides are usually enhanced by as follows the ideal strategy such as doping or substitution heterogeneous atoms. Here, a rare Earth metal ion of gadolinium (Gd3+) was doped with MoSe2 and synthesized through the hydrothermal method. The morphology and nanostructure of Gd3+ with MoSe2 spheres were analyzed under X-ray diffraction, Fourier-transform infrared spectroscopy, X-ray photoelectron, High-resolution transmission electron microscopy analysis, Field emission scanning electron microscopy, and energy-dispersive spectroscopy. Furthermore, the Gd3+ doped MoSe2 sphere modified glassy carbon electrode (Gd@MoSe2/GCE) was used for the sensing of tryptophan. The Gd@MoSe2 modified GCE shows remarkable sensing performance of tryptophan resulting in a linear range (20 nM-220 μM) with a low detection limit (6.7 nM). Under the optimal condition, the developed electrochemical sensor was successfully used to determine tryptophan (TrP) in blood serum and milk samples. The electrochemical biosensing results suggest that the doping of the Gd3+ doped MoSe2 sensor is a promising electrocatalyst in biological and food samples. © 2023 The Electrochemical Society ("ECS").

Microplastics (MPs) are pollutants generated by plastic debris of diameters ≤ 5 mm and are a global concern that can pose severe threats to human and environmental health in both aquatic and terrestrial areas. In this study, low-density polyethylene (LdPE, MW = ∼35000) blended with ru-incorporated g-C3N4 (ru-gCN) was fabricated to examine its degradation efficiency. Plastic film (ru-gCN@PE) degradation was performed by adding an aqueous medium with pH values ranging from 1 to 6 and at different temperatures (0, 35, 50, and 70 °C). The ru-gCN@PE showed a significant weight loss of approximately 66.04, 74.51, and 69.64 wt% in pH 3 at 0, 50, and 70 °C, respectively, upon light irradiation for 24 h. The high activity of ru-gCN can result from the formation of a heterojunction of ru and g-C3N4 (ru-gCN), which facilitates the transfer of the photoinduced π electrons of g-C3N4. Moreover, H+ is produced at an appropriate pH and temperature to further convert into hydroperoxides and accelerate the formation of macroradicals (∙rOO, ∙rO, and ∙OH) for plastic degradation, which follows the Norrish Type I and II mechanisms. Our study demonstrated the outstanding efficacy of the photocatalytic degradation of LdPE. © 2023 Elsevier B.V.

A comparative study of the surface contaminated layer formed by chemical reaction between ceramic-mold and titanium aluminum alloy castings or titanium alloy castings were carried out. The morphology, thickness and hardness of the surface contaminated layer were characterized by means of metalloscopy and microhardness measurement. The results show that surface contaminated layers formed between Ti-Al alloy castings and ceramic-mold, also formed between Ti alloy castings and ceramic-mold. The surface contaminated layers of Ti-Al alloy castings were continuous and compact, their thickness was about 0~90 μm. The surface contaminated layers of titanium alloy castings were not even, their thickness was 0~900 μm. Titanium alloy is more liable to react with the ceramic-mold than the Ti-Al alloy. © 2021 Trans Tech Publications Ltd, Switzerland.
