The density functional theory (DFT) in electronic structure calculations can be formulated as either a nonlinear eigenvalue or direct minimization problem. most widely used approach for solving the former is so-called self-consistent field (SCF) iteration. A common observation that convergence of SCF not clear theoretically, while approaches with guarantees latter are often competitive numerically. In this paper, we study gradient type methods problem by constructing new iterations along on...
In this paper, we propose an orbital iteration based parallel approach for electronic structure calculations. This is on our understanding of the single-particle equations independent particles that move in effective potential. With new approach, solution equation reduced to some solutions linear algebraic systems and a small scale problem. It demonstrated by numerical experiments quite efficient full-potential calculations class molecular systems.
In order to reduce the business platform's processing of massive IoT terminals and meet physical isolation differential quality assurance between different services, 5G slicing technology is used logically isolate network resources effectively protect differentiated service needs users, aiming at problem resource allocation during transmission in power grids. Maximize total throughput EMBB users minimize URLLC by jointly optimizing transmit downlink timeslot base station. Considering that...
3D dense captioning stands as a cornerstone in achieving comprehensive understanding of scenes through natural language. It has recently witnessed remarkable achievements, particularly indoor settings. However, the exploration outdoor is hindered by two major challenges: 1) \textbf{domain gap} between and scenes, such dynamics sparse visual inputs, makes it difficult to directly adapt existing methods; 2) \textbf{lack data} with box-caption pair annotations specifically tailored for scenes....
Outlier detection is one of the hot topics in field machine learning and data mining. At present, there are many kinds outlier algorithms. The accuracies traditional algorithms often affected by unique parameters, an increase amount dimensions can seriously affect their efficiency effectiveness. Methods based on generative adversarial networks (GANs) solve above problems, but they unacceptable since model collapses during training period. In this paper, to problems curse dimensionality...
Overhead transmission lines are important lifelines in power systems, and the research application of their intelligent patrol technology is one key technologies for building smart grids. The main reason low detection performance fittings wide range some fittings' scale large geometric changes. In this paper, we propose a method based on multi-scale transformation attention-masking mechanism. Firstly, design multi-view enhancement strategy, which models as combination multiple homomorphic...
We numerically demonstrate optically controlled THz response in a hybrid fishscale metamaterial with embedded photoconductive silicon at oblique incidence of TE wave. The allows excitation Fano-type trapped mode resonance 2-fold rotational symmetric metamaterial. exhibits an redshift switching effect the range. is dominated by conductivity instead mechanically adjusting angles incidence. tuning frequency range up to 0.3THz large modulation depth and high transmission “ON” state....
To investigate whether dynamic monitoring of citrulline (Cit) has guiding value for early enteral nutrition (EN) in patients with severe gastrointestinal injury.A observational study was conducted. A total 76 injury admitted to different intensive care units Suzhou Hospital Affiliated Nanjing Medical University from February 2021 June 2022 were enrolled. Early EN performed 24-48 hours after admission as recommended by the guidelines. Those who did not terminate 7 days enrolled success group,...
Traditional Softmax loss algorithm has only separability for features algorithm. This study proposed an improved to recognize facial features. The first applies intra class cosine similarity between the and weight vectors based on feature distribution, making more compact separating classes as much possible; then, basis of loss, we use normalized better simulate low-quality images, reduce category imbalance by normalizing weights ensure consistency with measurement during testing; finally,...

In-process measurement can provide feedback for control of workpiece precision in terms size, form error, and roughness. It be used a machining process, therefore to improve productivity reduce defect rates. Optical methods have greater advantages the in-process profile systems due their non-contact type high precision. However, use opaque coolant will introduce an barrier problem, making surface y(x, z) inaccessible optical devices. To solve this several approaches, including water beam...
