Authors: Oliaie Samira Sooreni , Safakish Mahdieh , Roudsari Rouhollah Vahabpour , Mahboubi-Rabbani Mohammad , Hajimahdi Zahra , Zarghi Afshin
Published: November 2023

Background:

The persistence of HIV mutations and the existence of multidrug resistance
have produced an opportunity for an array of innovative anti-HIV medicines with a variety
of structures that target HIV key enzymes.

Objective:

The goal of this work was to find a new class of anti-HIV drugs founded on HIV integrase
inhibitor pharmacophores.

Method:

A novel class of 2-hydroxy acetophenone analogs featuring substituted benzamide or
N-phenylthiourea groups was designed and synthesized based on the general pharmacophore of
HIV-1 integrase inhibitors (INs).

Results:

Most of the synthesized analogs were found to be moderately active against the virus,
with EC50 values ranging from 40 to 140 μM. Additionally, it was found that most of the compounds
presented no considerable cytotoxicity (CC50 > 500 μΜ). The most potent compounds substituting
with 4-fluorobenzamide (compound 7) and 4-methylbenzamide (compound 9) rings inhibited
the HIV-1 replication by EC50 values of 40 and 45 μΜ, respectively. Docking studies using
the crystallographic data available for PFV IN indicated that the Mg2+ coordination might be
the possible mechanism of the anti-viral activity.

Conclusion:

Our findings proved that the synthesized analogs may suggest a very good basis for
the development of new anti-HIV-1 agents.
Strategy for Targeting Medical Diagnosis of Cerebral Ischemia Regions by Linking Gsk-3β Antibody and RVG29 to Magnetosomes
Authors: Wang Qing , Li Xianyu
Published: November 2023

Background:

In our previous studies, we have identified Gsk-3β as a crucial target
molecule in response to Danhong injection for cerebral ischemia intervention. Furthermore, it
can serve as a molecular imaging probe for medical diagnosis. Bacterial magnetic particles
(BMPs), synthesized by magnetotactic bacteria, are regarded as excellent natural nanocarriers.

Methods:

In this study, we utilized biological modification and chemical crosslinking techniques
to produce a multifunctional BMP known as "RVG29-BMP-FA-Gsk-3β-Ab", which exhibits
both magnetic properties and brain-targeting capabilities. Then, a combination of analytical
techniques was used to characterize the properties of the multifunctional BMPs. Finally, we
evaluated the cell targeting ability of the RVG29-BMP-FA-Gsk-3β-Ab.

Results:

The multifunctional BMPs were observed to possess uniform size and shape using
TEM analysis, with a particle size of 70.1±7.33 nm. Zeta potential analysis revealed that the
nanoparticles exhibited a regular and non-aggregative distribution of particle sizes. Relative
fluorescence intensity results demonstrated that the complex of 1mg of RVG29-BMP-FA-Gsk-
3β-Ab could bind to FITC-RVG29 polypeptide at a concentration of 2189.5 nM. Cell viability
analysis indicated its high biocompatibility and minimal cytotoxicity. The RVG29-BMP-FAGsk-
3β-Ab was observed to possess active targeting towards neuronal cells and fluorescence
imaging capabilities in vitro, as evidenced by fluorescence imaging assays. The complex of
RVG29-BMP-FA-Gsk-3β-Ab exhibited favourable properties for early diagnosis and efficacy
evaluation of traditional Chinese medicine in treating cerebral ischemia.

Conclusion:

This study establishes a fundamental basis for the prospective implementation of
multimodal imaging in traditional Chinese medicine for cerebral ischemia.

many unexpected ADRs of drugs are reported through post-marketing surveillance.

Aim:

The current study's goal is to uncover potential signals connected with FDA-approved medications
in the United States (2013).

Methods:

Open Vigil 2.1-MedDRA-v24 (data 20004Q1-2021Q3) was used as a tool to query the
FAERS data. To find possible signals, disproportionality measures such as Proportional Reporting
Ratio (PRR 2) with associated Chi-square value, Reporting Odds Ratio (ROR 2) with 95%
confidence interval, and case count (3) were calculated

Results:

A total of eight potential signals were identified with five drugs. Positive signals were
found with pomalidomide, canagliflozin, dolutegravir sodium, macitentan and ibrutinib.

Conclusion:

However, further causality assessment is required to confirm the association of these

Comparative Study of Vital Sign Monitoring Techniques and Methods using Radar Sensor
Authors: Pushparaj  , Kumar Amod , Saini Garima
Published: November 2023

COVID-19 (Corona Virus Disease of 2019) is a global pandemic caused by the Severe
Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus. This disease has significantly
impacted every aspect of people's lives, including their work style, leisure activities, and use of
technology. Additionally, due to psychological factors or other reasons, there has been a surge in
deaths from cardiovascular failure during the pandemic. As COVID-19 is a silent killer whose
symptoms only become visible after significant damage has been done, constant monitoring of
heart parameters is crucial to address this issue. This paper explores the emerging trends in monitoring
vital signs such as the electrocardiogram (ECG), heart rate, respiration rate (breaths), related
sensors, remote sensor organization, and telemedicine innovations. Furthermore, this paper
discusses the potential application of non-contact radar-based remote monitoring for vital sign
monitoring of affected patients.
Assessing the Usefulness of Mobile Apps for Noise Management in Occupational Health and Safety: Quantitative Measurement and Expert Elicitation Study
Authors: Huyan Jingchen , Ramkissoon Chandnee , Laka Mah , Gaskin Sharyn
Published: November 2023

Background

Overexposure to occupational noise can lead to hearing loss. Occupational noise mapping is conventionally performed with a calibrated sound level meter (SLM). With the rise of mobile apps, there is a growing number of SLM apps available on mobile phones. However, few studies have evaluated such apps for accuracy and usefulness to guide those with occupational noise detection needs in selecting a quality app.

Objective

The purpose of this study was to evaluate the accuracy and usefulness of SLM mobile apps to guide workplace health and safety professionals in determining these apps’ suitability for assessing occupational noise exposure.

Methods

The following three iOS apps were assessed: the NIOSH (National Institute for Occupational Safety and Health) Sound Level Meter, Decibel X, and SoundMeter X apps. The selected apps were evaluated for their accuracy in measuring sound levels in low-, moderate-, and high-noise settings within both simulated environments and real-world environments by comparing them to a conventional SLM. The usefulness of the apps was then assessed by occupational health specialists using the Mobile App Rating Scale (MARS).

Results

The NIOSH Sound Level Meter app accurately measured noise across a range of sound levels in both simulated settings and real-world settings. However, considerable variation was observed between readings. In comparison, the Decibel X and SoundMeter X apps showed more consistent readings but consistently underestimated noise levels, suggesting that they may pose a risk for workers. Nevertheless, none of the differences in sound measurements between the three apps and the conventional SLM were statistically significant (NIOSH Sound Level Meter: P=.78; Decibel X: P=.38; SoundMeter X: P=.40). The MARS scores for the three apps were all above 3.0, indicating the usefulness of these apps.

Conclusions

Under the conditions of this study, the NIOSH Sound Level Meter app had equivalent accuracy to the calibrated SLM and a degree of usefulness according to the MARS. This suggests that the NIOSH Sound Level Meter app may be suitable for mapping noise levels as part of a monitoring strategy in workplaces. However, it is important to understand its limitations. Mobile apps should complement but not replace conventional SLMs when trying to assess occupational noise exposure risk. Our outcomes also suggest that the MARS tool may have limited applicability to measurement-based apps and may be more suited to information-based apps that collect, record, and store information.

Authors: Beesoon Sanjay , Drobot Ashley , Smokeyday Melissa , Ali Al-Bakir , Collins Zoe , Reynolds Colin , Berzins Sandra , Gibson Alison , Nelson Gregg
Published: November 2023

Background

Of all the care provided in health care systems, major surgical interventions are the costliest and can carry significant risks. Enhanced Recovery After Surgery (ERAS) is a bundle of interventions that help improve patient outcomes and experience along their surgical journey. However, given that patients can be overwhelmed by the multiple tasks that they are expected to follow, a digital application, the ERAS app, was developed to help improve the implementation of ERAS.

Objective

The objective of this work was to conduct a thorough assessment of patient and provider experiences using the ERAS app.

Methods

Patients undergoing colorectal or gynecological oncology surgery at 2 different hospitals in the province of Alberta, Canada, were invited to use the ERAS app and report on their experiences using it. Likewise, care providers were recruited to participate in this study to provide feedback on the performance of this app. Data were collected by an online survey and using qualitative interviews with participants. NVivo was used to analyze qualitative interview data, while quantitative data were analyzed using Excel and SPSS.

Results

Overall, patients found the app to be helpful in preparation for and recovery after surgery. Patients reported having access to reliable unbiased information regarding their surgery, and the app provided them with clarity of actions needed along their surgical journey and enhanced the self-management of their care. Clinicians found that the ERAS app was easy to navigate, was simple for older adults, and has the potential to decrease unnecessary visits and phone calls to care providers. Overall, this proof-of-concept study on the use of a digital health app to accompany patients during their health care journey has shown positive results.

Conclusions

This is an important finding considering the massive investment and interest in promoting digital health in health care systems around the world.
Dentists’ Information Needs and Opinions on Accessing Patient Information via Health Information Exchange: Survey Study
Authors: Li Shuning , Felix Gomez Grace Gomez , Xu Huiping , Rajapuri Anushri Singh , Dixon Brian E , Thyvalikakath Thankam
Published: November 2023

Background

The integration of medical and dental records is gaining significance over the past 2 decades. However, few studies have evaluated the opinions of practicing dentists on patient medical histories. Questions remain on dentists’ information needs; their perception of the reliability of patient-reported medical history; satisfaction with the available information and the methods to gather this information; and their attitudes to other options, such as a health information exchange (HIE) network, to collect patient medical history.

Objective

This study aims to determine Indiana dentists’ information needs regarding patients’ medical information and their opinions about accessing it via an HIE.

Methods

We administered a web-based survey to Indiana Dental Association members to assess their current medical information-retrieval approaches, the information critical for dental care, and their willingness to access or share information via an HIE. We used descriptive statistics to summarize survey results and multivariable regression to examine the associations between survey respondents’ characteristics and responses.

Results

Of the 161 respondents (161/2148, 7.5% response rate), 99.5% (n=160) respondents considered patients’ medical histories essential to confirm no contraindications, including allergies or the need for antibiotic prophylaxis during dental care and other adverse drug events. The critical information required were medical conditions or diagnosis, current medications, and allergies, which were gathered from patient reports. Furthermore, 88.2% (n=142) of respondents considered patient-reported histories reliable; however, they experienced challenges obtaining information from patients and physicians. Additionally, 70.2% (n=113) of respondents, especially those who currently access an HIE or electronic health record, were willing to use an HIE to access or share their patient’s information, and 91.3% (n=147) shared varying interests in such a service. However, usability, data accuracy, data safety, and cost are the driving factors in adopting an HIE.

Conclusions

Patients’ medical histories are essential for dentists to optimize dental care, especially for those with chronic conditions. In addition, most dentists are interested in using an HIE to access patient medical histories. The findings from this study can provide an alternative option for improving communications between dental and medical professionals and help the health information technology system or tool developers identify critical requirements for more user-friendly designs.
Daily Activity Lifelogs of People With Heart Failure: Observational Study
Authors: Tegegne Teketo Kassaw , Tran Ly-Duyen , Nourse Rebecca , Gurrin Cathal , Maddison Ralph
Published: November 2023

Background

Globally, heart failure (HF) affects more than 64 million people, and attempts to reduce its social and economic burden are a public health priority. Interventions to support people with HF to self-manage have been shown to reduce hospitalizations, improve quality of life, and reduce mortality rates. Understanding how people self-manage is imperative to improve future interventions; however, most approaches to date, have used self-report methods to achieve this. Wearable cameras provide a unique tool to understand the lived experiences of people with HF and the daily activities they undertake, which could lead to more effective interventions. However, their potential for understanding chronic conditions such as HF is unclear.

Objective

This study aimed to determine the potential utility of wearable cameras to better understand the activities of daily living in people living with HF.

Methods

The “Seeing is Believing (SIB)” study involved 30 patients with HF who wore wearable cameras for a maximum of 30 days. We used the E-Myscéal web-based lifelog retrieval system to process and analyze the wearable camera image data set. Search terms for 7 daily activities (physical activity, gardening, shopping, screen time, drinking, eating, and medication intake) were developed and used for image retrieval. Sensitivity analysis was conducted to compare the number of images retrieved using different search terms. Temporal patterns in daily activities were examined, and differences before and after hospitalization were assessed.

Results

E-Myscéal exhibited sensitivity to specific search terms, leading to significant variations in the number of images retrieved for each activity. The highest number of images returned were related to eating and drinking, with fewer images for physical activity, screen time, and taking medication. The majority of captured activities occurred before midday. Notably, temporal differences in daily activity patterns were observed for participants hospitalized during this study. The number of medication images increased after hospital discharge, while screen time images decreased.

Conclusions

Wearable cameras offer valuable insights into daily activities and self-management in people living with HF. E-Myscéal efficiently retrieves relevant images, but search term sensitivity underscores the need for careful selection.
Medical Extended Reality Trials: Building Robust Comparators, Controls, and Sham (Preprint)
Authors: Persky Susan , Colloca Luana
Published: November 2023

UNSTRUCTURED

The explosive pace of development and research in medical extended reality (MXR) is a testament to its promise for health care and medicine. In comparison with this growth, there is a relative sparsity of rigorous clinical trials that establish the efficacy and effectiveness of these interventions. Explicating mechanisms of action across clinical areas and MXR applications is another major area of need. A primary impediment to these goals is a lack of frameworks for trial design, more specifically, the selection of appropriate controls that effectively address unique elements of MXR. This paper delineates a framework for designing controls, sham conditions, and comparators, as well as proposed considerations for MXR trial designs. Special consideration is given to the design of sham conditions. Improved designs would enable more robust findings and the development of generalizable knowledge that could be adopted across MXR interventions.
La nave va o de cómo surcar el mar de asfalto de la salud mental
Authors: Carvajal Alberto
Published: November 2023

El video La nave va, que es el resultado de un taller fotográfico organizado en colaboración con la uam-Xochimilco y llevado a cabo en el Hospital Psiquiátrico Público Dr. Samuel Ramírez Moreno, situado en los límites de Tláhuac y Chalco. Este taller fue iniciado por Miguel, uno de los pacientes que se convirtieron en fotógrafos y que demostró un gran entusiasmo. En la curación de las imágenes, se destaca un tema recurrente: el movimiento. Los cuerpos en movimiento parecen ser una forma de resistencia política y radical contra el concepto de instituciones totales y de encierro. A pesar de la crítica implícita en estos estudios, los habitantes del hospital transforman el encierro en movimiento, convirtiendo la vida oculta en una interpelación a nuestra indiferencia. Lo que Foucault describió como la “nave de los locos” en su Historia de la locura se convierte, según el autor, en un hospital deprimente, pero estos pacientes lo transforman nuevamente en una nave que surca las calles de la periferia de la gran metrópoli.
Punto de quiebre y de partida: descubrirse autista
Authors: Montejano Fluchaire Liz
Published: November 2023

El número de diagnósticos de Trastorno del Espectro Autista (tea) en adultos ha aumentado gracias al entendimiento de las dificultades psicosociales del autismo, ampliando los criterios diagnósticos para incluir manifestaciones sutiles. Sin embargo, la “generación perdida” de autistas a menudo pasa desapercibida debido a las estrategias de camuflaje que desarrollan para adaptarse al mundo neurotípico. Estas estrategias, combinadas con cambios significativos en la vida, pueden sobrepasar su capacidad de gestionar la información socio-afectiva. Bajo estas circunstancias, se descubre la condición autista en la adultez. Pero es importante destacar que sólo una minoría de autistas que buscan ayuda en salud mental obtienen un diagnóstico adecuado de tea. Este fenómeno plantea desafíos clave en el diagnóstico y enfatiza la necesidad de comprensión y conciencia sobre la experiencia de los adultos autistas en su búsqueda de identidad y aceptación.

The endothelium is a monolayer of flatten cells named endothelial cells that form the inner layer of the heart, blood, and lymphatic vessels. Its function is not just as a barrier, but it is a regulator of vascular permeability and tone, hemostasis, inflammation, and angiogenesis. This review is about the general aspects of vascular endothelium and endothelial dysfunction that leads to increased vascular risk. Activation and dysfunction are discussed, considering the endothelialactivation as a self-limiting process, necessary to promote inflammation and hemostasis. Endothelial dysfunction is a pathological process in which the endothelium loses its ability for self-regulation and acquires a prothrombotic and proinflammation phenotype. Endothelial dysfunction is the initial step for atherosclerosis and increased cardiovascular risk, so the main biomarkers of endothelial dysfunction are reviewed. As basic knowledge about endothelium increases, preventive or therapeutic measures can be designed as treatment or prevention the risk of its dysfunction. Key words: Healthy endothelium; activation; endothelial; endothelial dysfunction; cardiovascular risk; atherosclerosis.

Authors: Balani Bhavika
Published: November 2023

Abstract: In the ever-evolving landscape of machine learning and deep neural networks, the demand for training large models on massive datasets has driven research into innovative approaches for efficient distributed optimization. These approaches aim to simultaneously improve model accuracy and generalization while mitigating the communication overhead challenges inherent to distributed training. Reduced communication complexity is highly desirable, as communication overhead often poses a performance bottleneck in distributed systems. This literature review explores the progression of communication-efficient techniques, culminating in the introduction of the Slow Momentum (SLOWMO) framework. It traces the trajectory of distributed optimization, addresses decentralization strategies, and highlights the role of Local Stochastic Gradient Descent (Local SGD) and momentum in communication-efficient algorithms. It delves into Block-Wise Model Update Filtering (BMUF) and introduces SLOWMO, a framework consistently enhancing optimization and generalization performance across various base algorithms. This review unveils the evolving field of communication-efficient distributed optimization, offering theoretical guarantees and practical insights for improving large-scale model training.

Published: November 2023

Previously proposed quantum algorithms for solving linear systems of equations cannot be implemented in the near term due to the required circuit depth. Here, we propose a hybrid quantum-classical algorithm, called Variational Quantum Linear Solver (VQLS), for solving linear systems on near-term quantum computers. VQLS seeks to variationally prepare |x⟩ such that A|x⟩∝|b⟩. We derive an operationally meaningful termination condition for VQLS that allows one to guarantee that a desired solution precision ϵ is achieved. Specifically, we prove that C⩾ϵ2/κ2, where C is the VQLS cost function and κ is the condition number of A. We present efficient quantum circuits to estimate C, while providing evidence for the classical hardness of its estimation. Using Rigetti's quantum computer, we successfully implement VQLS up to a problem size of 1024×1024. Finally, we numerically solve non-trivial problems of size up to 250×250. For the specific examples that we consider, we heuristically find that the time complexity of VQLS scales efficiently in ϵ, κ, and the system size N.

LEXICAL ATTRITION IN MULTILINGUAL LANGUAGE LEARNERS
Authors: Ulfiati Lilik
Published: November 2023

Multilingual language learners are facing various challenges of language attrition, both internally and externally. Lexical attrition is one of phenomena experienced by the learners since they can no longer do something which s/he had previously been able to do, and this loss of proficiency is not caused by deterioration of the brain due to age, illness or injury, but by changes in linguistic behaviour due to  severance of the contact with the community in which the language is spoken (Smith, 2017). This article is trying to capture the studies of lexical attrition in the multilingual contexts and suggest several improvement strategies in experiencing the lexical attrition. This study is using content analysis to explore existing literature on lexical attrition in multilingual language learners over the last ten years. A summary of more than seventeen is provided along with the content analysis. The finding of these studies gives a significant contribution to the field of language attrition that focuses on practical analysis in learners or speakers points of view in the multilingual context. It shows that the limitation of understanding on lexical attrition concept from the local authorities in many educational settings have resulted in less efficient and effective language maintenance.

Cita-cita petani kelapa sawit memiliki pabrik CPO  sudah menjadi wacana secara nasional maupun lokal. Untuk mewujudkan cita-cita itu tentu menghendaki pengetahuan dan pemahaman yang cukup dari petani tentang deskripsi pabrik tersebut, bagaimana teknologi dan bagaimana manajemennya. Permasalahannya adalah tidak semua petani paham atau mengerti tentang bagaimana proses membangun pabrik, teknologi yang digunakan, dan sistem pengelolaannya serta manfaat apa yang akan diterimanya. Untuk mewujudkan hal itu maka petani/pekebun perlu diberi ruang yang cukup dalam cara berpikir dan bertindak sehingga keputusan yang diambil merupakan keputusan kolektif. Penyuluhan tentang pengenalan teknologi, manajemen dan pabrik kelapa sawit mini menuju kemandirian petani dalam pengelolaan TBS di KUD Marga Jaya Desa Petaling untuk mendapatkan pengetahuan tentang teknologi dan pengelolaan pabrik CPO, dan pengetahuan tentang pabrik CPO berskala mini.  Kegiatan ini dilaksanakan ditengah Pandemi Covid -19 sehingga peserta hanya dipilih dari para ketua kelompok tani dan pengurus KUD. Hasilnya menunjukkan bahwa respon terhadap pelaksanaan sosialisasi cukup baik dan disertai harapan terjadi transfer pengetahuan secara lebih luas dan berkesinambungan di tengah petani kelapa sawit setempat.
Finding value in sustainable and responsible investments
Authors: Lobe Sebastian , Halbritter Gerhard
Published: November 2023

This paper assesses the characteristics and financial performance of a comprehensive set of passive sustainable and responsible investments (SRI) around the world. We contribute the novel finding that from a financial perspective, SRI portfolios pursue first and foremost a pure value strategy when using an undistorted value measure. This result holds irrespective of the index provider, the screening, and the weighting approach. It is also robust across international markets and to various asset pricing anomalies such as size, momentum, short-term reversal, betting-against-beta, and quality-minus-junk. We corroborate that SRI’s financial performance is neutral with slight indications that score-weighting or a combined approach using positive and negative environmental, social and governance (ESG) screens fare better
Generalized Alpha Power Inverted Weibull Distribution: Application of Air Pollution in Kathmandu, Nepal
Authors: Dhungana Govinda Prasad , Chaudhary Arun Kumar , Tharu Ramesh Prasad , Kumar Vijay
Published: November 2023

A novel probability distribution, the Generalized Alpha Power
Inverted Weibull (GAPIW) distribution, is derived from the
generalization of the
-power family and compounded with the
inverted Weibull distribution. The researchers have extensively explored
various sub-models and established essential properties of the GAPIW
distribution, including the quintile function, median, mode, moments,
mean residual lifetime, and stress-strength reliability. The estimation
of distribution parameters was carried out through maximum likelihood
estimation methods.
To gain insights into the characteristics of
the GAPIW distribution, the study applied it to the analysis of air
pollution data, specifically PM2.5, PM10, and TSP data from multiple
stations in the Kathmandu Valley, including Bhaktapur, Bhaisepati,
Kirtipur, and Ratna Park. Notably, the findings indicate that air
quality in these areas was significantly worse during winter than in
other seasons. Also, the ratio (PM2.5/PM10) of particulate matter is
higher, indicating air pollution from anthropogenesis particles in the
Valley.
The results demonstrate that the GAPIW distribution is
validated through different diagrammatic representations, such as P-P
plots, Q-Q plots, and mathematical calculations like the K-S test. The
findings reveal that, on average, only three days per month or one month
per year predict air pollution levels below the threshold in the
Kathmandu Valley. Furthermore, compared to others
-power family
of distribution available in the literature, the proposed GAPIW
distribution stands as a viable alternative model for assessing and
understanding air pollution data and related environmental data. This
research has the potential to make valuable contributions to the field
of environmental science and air quality monitoring.
Weighted Sampling based Large-scale Enclosing Subgraphs Embedding for Link Prediction
Authors: Hu Ganglin
Published: November 2023

Link prediction is a fundamental problem for graphs, which can reveal
the potential relationships between users. Graph embedding can easily
encode graph structural relations, and heterogeneous attribute features
in a continuous vector space, which is effective in link prediction.
However, graph embedding methods for large-scale graphs suffer high
computation and space costs, and sampling enclosing subgraphs is a
practical yet efficient way to obtain the most features at the least
cost. Nevertheless, the existing sampling techniques may lose essential
features when the random sampling number of nodes is not large, as node
features are assumed to follow a uniform distribution. In this paper, we
propose a novel enclosing subgraph embedding model named Weighted
Sampling Enclosing-subgraph Embedding (WSEE) to resolve this issue,
which maximumly preserves the structural and attribute features of
enclosing subgraphs with less sampling. More specifically, we first
extract the feature importance of each node in an enclosing subgraph and
then take the node importance as node weight. Then, random walks node
sequences are obtained by multiple weighted random walks from a target
pair of nodes, generating a weighted sampling enclosing subgraph. By
leveraging the weighted sampling enclosing subgraph, WSEE can scale to
larger graphs with much less overhead while maintaining some essential
information of the original graph. Experiments on real-world datasets
demonstrate that our model can scale to larger graphs with acceptable
overhead while link prediction performance is unaffected.
