LAGOS-AND: A Large Gold Standard Dataset for Scholarly Author Name Disambiguation
In this paper, we present a method to automatically build large labeled
datasets for the author ambiguity problem in the academic world by leveraging
the authoritative academic resources, ORCID and DOI. Using the method, we built
LAGOS-AND, two large, gold-standard datasets for author name disambiguation
(AND), of which LAGOS-AND-BLOCK is created for clustering-based AND research
and LAGOS-AND-PAIRWISE is created for classification-based AND research. Our
LAGOS-AND datasets are substantially different from the existing ones. The
initial versions of the datasets (v1.0, released in February 2021) include 7.5M
citations authored by 798K unique authors (LAGOS-AND-BLOCK) and close to 1M
instances (LAGOS-AND-PAIRWISE). And both datasets show close similarities to
the whole Microsoft Academic Graph (MAG) across validations of six facets. In
building the datasets, we reveal the variation degrees of last names in three
literature databases, PubMed, MAG, and Semantic Scholar, by comparing author
names hosted to the authors' official last names shown on the ORCID pages.
Furthermore, we evaluate several baseline disambiguation methods as well as the
MAG's author IDs system on our datasets, and the evaluation helps identify
several interesting findings. We hope the datasets and findings will bring new
insights for future studies. The code and datasets are publicly available.Comment: 33 pages, 7 tables, 7 figure
Diagnosis of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery with Echocardiography and Digital Subtraction Angiography
Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a common coronary artery anomaly associated with high mortality and may lead to sudden death if left unrecognized and untreated. This report describes an 8-year-old female who had cardiac murmur but with no clinical symptoms. Electrocardiogram (ECG) was normal, but echocardiography made the diagnosis of ALCAPA. Digital subtraction angiography (DSA) with cardiac catheterization angiography (CAG) confirmed the diagnosis, and finally, the patient received surgery. This case demonstrates that echocardiography is a sensitive and convenient technique for establishing the initial diagnosis of ALCAPA in both symptomatic and asymptomatic patients
An Optimization Sizing Model for Solar Photovoltaic Power Generation System with Pumped Storage
AbstractIn this study, a novel sizing model for the solar photovoltaic system with pumped storage is proposed, to optimize the capacity of the PV generator and pumped storage system for power supply in remote areas. The genetic algorithm is then employed to optimize sizing system with respect to the system total cost. The variables considered in the optimization process include PV module number, upper reservoir size and water pump size. With the developed model, a technically and economically feasible power supply solution can be achieved easily. The proposed model is finally applied to a case study on renewable energy power generation system for an island, and the optimization performance has been demonstrated
Allocating Limited Resources to Protect a Massive Number of Targets using a Game Theoretic Model
Resource allocation is the process of optimizing the rare resources. In the
area of security, how to allocate limited resources to protect a massive number
of targets is especially challenging. This paper addresses this resource
allocation issue by constructing a game theoretic model. A defender and an
attacker are players and the interaction is formulated as a trade-off between
protecting targets and consuming resources. The action cost which is a
necessary role of consuming resource, is considered in the proposed model.
Additionally, a bounded rational behavior model (Quantal Response, QR), which
simulates a human attacker of the adversarial nature, is introduced to improve
the proposed model. To validate the proposed model, we compare the different
utility functions and resource allocation strategies. The comparison results
suggest that the proposed resource allocation strategy performs better than
others in the perspective of utility and resource effectiveness.Comment: 14 pages, 12 figures, 41 reference
Hybrid-SORT: Weak Cues Matter for Online Multi-Object Tracking
Multi-Object Tracking (MOT) aims to detect and associate all desired objects
across frames. Most methods accomplish the task by explicitly or implicitly
leveraging strong cues (i.e., spatial and appearance information), which
exhibit powerful instance-level discrimination. However, when object occlusion
and clustering occur, both spatial and appearance information will become
ambiguous simultaneously due to the high overlap between objects. In this
paper, we demonstrate that this long-standing challenge in MOT can be
efficiently and effectively resolved by incorporating weak cues to compensate
for strong cues. Along with velocity direction, we introduce the confidence
state and height state as potential weak cues. With superior performance, our
method still maintains Simple, Online and Real-Time (SORT) characteristics.
Furthermore, our method shows strong generalization for diverse trackers and
scenarios in a plug-and-play and training-free manner. Significant and
consistent improvements are observed when applying our method to 5 different
representative trackers. Further, by leveraging both strong and weak cues, our
method Hybrid-SORT achieves superior performance on diverse benchmarks,
including MOT17, MOT20, and especially DanceTrack where interaction and
occlusion are frequent and severe. The code and models are available at

Attention-Based Deep Learning Model for Predicting Collaborations Between Different Research Affiliations
It is challenging but important to predict the collaborations between different entities which in
academia, for example, would enable finding evaluating trends of scientific research collaboration and the
provision of decision support for policy formulation and incentive measures. In this paper, we propose an
attention-based Long Short-Term Memory Convolutional Neural Network (LSTM-CNN) model to predict
the collaborations between different research affiliations, which takes both the influence of research articles
and time (year) relationships into consideration. The experimental results show that the proposed model
outperforms the competitive Support Vector Machine (SVM), CNN and LSTM methods. It significantly
improves the prediction precision by a minimum of 3.23 percent points and up to 10.80 percent points
when compared with the mentioned competitive methods, while in terms of the F1-score, the performance
is improved by 13.48, 4.85 and 4.24 percent points, respectively.This work was supported in part by the Humanities and Social Science Research Project of the Ministry of Education in China under

Perinatal Blockade of B7-1 and B7-2 Inhibits Clonal Deletion of Highly Pathogenic Autoreactive T Cells
A number of in vitro studies have suggested that costimulatory molecules B7-1 and B7-2 and their receptor CD28 can promote clonal deletion, and limited in vivo studies have indicated that CD28 is involved in the clonal deletion of some T cells. However, the significance of B7-mediated clonal deletion in preventing autoimmune diseases has not been studied systematically. Here we report that the perinatal blockade of B7-1 and B7-2 substantially inhibits the clonal deletion of T cells in the thymus and leads to an accumulation of T cells capable of inducing fatal multiorgan inflammation. These results reveal a critical role for costimulatory molecules B7-1 and B7-2 in deleting pathogenic autoreactive T cells in the thymus. The critical role of B7-1 and B7-2 in T cell clonal deletion may explain, at least in part, the paradoxical increase of autoimmune disease in mice deficient for this family of costimulatory molecules, such as cytotoxic T lymphocyte associated molecule 4, CD28, and B7-2. The strong pathogenicity of the self-reactive T cells supports a central hypothesis in immunology, which is that clonal deletion plays an important role in preventing autoimmune diseases
The utility of methylmalonic acid, methylcitrate acid, and homocysteine in dried blood spots for therapeutic monitoring of three inherited metabolic diseases
BackgroudRoutine metabolic assessments for methylmalonic acidemia (MMA), propionic acidemia (PA), and homocysteinemia involve detecting metabolites in dried blood spots (DBS) and analyzing specific biomarkers in serum and urine. This study aimed to establish a liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for the simultaneous detection of three specific biomarkers (methylmalonic acid, methylcitric acid, and homocysteine) in DBS, as well as to appraise the applicability of these three DBS metabolites in monitoring patients with MMA, PA, and homocysteinemia during follow-up.MethodsA total of 140 healthy controls and 228 participants were enrolled, including 205 patients with MMA, 17 patients with PA, and 6 patients with homocysteinemia. Clinical data and DBS samples were collected during follow-up visits.ResultsThe reference ranges (25th–95th percentile) for DBS methylmalonic acid, methylcitric acid, and homocysteine were estimated as 0.04–1.02 μmol/L, 0.02–0.27 μmol/L and 1.05–8.22 μmol/L, respectively. Following treatment, some patients achieved normal metabolite concentrations, but the majority still exhibited characteristic biochemical patterns. The concentrations of methylmalonic acid, methylcitric acid, and homocysteine in DBS showed positive correlations with urine methylmalonic acid (r = 0.849, p < 0.001), urine methylcitric acid (r = 0.693, p < 0.001), and serum homocysteine (r = 0.721, p < 0.001) concentrations, respectively. Additionally, higher levels of DBS methylmalonic acid and methylcitric acid may be associated with increased cumulative complication scores.ConclusionThe LC–MS/MS method established in this study reliably detects methylmalonic acid, methylcitric acid, and homocysteine in DBS. These three DBS metabolites can be valuable for monitoring patients with MMA, PA, and homocysteinemia during follow-up. Further investigation is required to determine the significance of these DBS biomarkers in assessing disease burden over time
