EXACT PHYLODYNAMIC LIKELIHOOD VIA STRUCTURED MARKOV GENEALOGY PROCESSES. Open
We show that each member of a broad class of Markovian population models induces a unique stochastic process on the space of genealogies. We construct this genealogy process and derive exact expressions for the likelihood of an observed ge…

The Number and Pattern of Viral Genomic Reassortments are not Necessarily Identifiable from Segment Trees Open
Reassortment is an evolutionary process common in viruses with segmented genomes. These viruses can swap whole genomic segments during cellular co-infection, giving rise to novel progeny formed from the mixture of parental segments. Since …

A story of viral co-infection, co-transmission and co-feeding in ticks: how to compute an invasion reproduction number Open
With a single circulating vector-borne virus, the basic reproduction number incorporates contributions from tick-to-tick (co-feeding), tick-to-host and host-to-tick transmission routes. With two different circulating vector-borne viral str…

Research on the Comprehensive Impact of ESG Indicators on Supply Chain Sustainability, Economic Growth, and Policy Making Open
This article aims to study the comprehensive impact of ESG (Environmental, Social, and Governance) indicators on supply chain sustainability, economic growth, and policy making. Through comprehensive analysis of relevant research and cases…

Modeling the evolution of segment trees reveals deficiencies in current inferential methods for genomic reassortment Open
Reassortment is an evolutionary process common in viruses with segmented genomes. These viruses can swap whole genomic segments during cellular co-infection, giving rise to new viral variants. Large-scale genome rearrangements, such as rea…

Seeing through noise in power laws Open
Despite widespread claims of power laws across the natural and social sciences, evidence in data is often equivocal. Modern data and statistical methods reject even classic power laws such as Pareto’s law of wealth and the Gutenberg–Richte…

Swift and exhaustive Omicron outbreak in China after sudden exit from ‘zero-COVID’ policy Open
In late 2022, China transitioned from a strict ‘zero-COVID’ policy to rapidly abandoning nearly all interventions and data reporting. This raised great concern about the presumably-rapid but undisclosed spread of the SARS-CoV-2 Omicron var…

Tunable robustness in power-law inference Open
Power-law probability distributions arise often in the social and natural sciences. Statistics have been developed for estimating the exponent parameter as well as gauging goodness-of-fit to a power law. Yet paradoxically, many famous powe…

Sparse Attentive Memory Network for Click-through Rate Prediction with Long Sequences Open
Sequential recommendation predicts users' next behaviors with their\nhistorical interactions. Recommending with longer sequences improves\nrecommendation accuracy and increases the degree of personalization. As\nsequences get longer, exist…

Changing Epidemiology of TB in Shandong, China Driven by Demographic Changes Open
Tuberculosis (TB) incidence has been in steady decline in China over the last few decades. However, ongoing demographic transition, fueled by aging, and massive internal migration could have important implications for TB control in the fut…

Decreased Case Fatality Rate of COVID‐19 in the Second Wave: A study in 53 countries or regions Open
The raw case fatality rate (CFR, the reported number of COVID-19 deaths divided by the total number of cases) is an important indicator to quantify the severity or treatment efficacy. In many countries, the pandemic had experienced two wav…

New estimates of the Zika virus epidemic attack rate in Northeastern Brazil from 2015 to 2016: A modelling analysis based on Guillain-Barré Syndrome (GBS) surveillance data Open
The GBS surveillance data can be used to study ZIKV epidemics and may be appropriate when ZIKV reporting rates are not well understood. The overall infection attack rate (IAR) of ZIKV is estimated to be 24.1% (95% confidence interval: 17.1…
