Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Unveiling the Spatial Heterogeneity of Urban Vitality Using Machine Learning Methods: A Case Study of Tianjin, China

open access: yesLand
The impact of the built environment (BE) on urban vitality (UV) has become a key issue in the field of urban planning. However, few studies have explored the impact of the BE on UV from the perspective of urban function zones (UFZs).

"Threshold Effects in the U.S. Budget Deficit" [PDF]

open access: yes
We contribute to the debate on whether the large U.S. federal budget deficits are sustainable in the long run. We model the U.S. government deficit per capita as a threshold autoregressive process. We find evidence that the U.S.

Threshold signatures from VOLE

open access: yes, 2023
reservedThe focus of this thesis is on threshold digital signatures and in particular on Schnorr signatures (1991). Following the expiration of its patent in 2008, Schnorr signature has gained significance in the realm of digital signatures due to its ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Research on the impact and mechanism of green credit on carbon emissions

open access: yesFrontiers in Sustainability
This paper examines the relationship between green credit and carbon emissions using balanced provincial panel data from China (2012–2024). A two-way fixed effects model serves as the baseline framework, with mediation and threshold analyses exploring ...

Threshold Effects in Cigarette Addiction: An Application of the Threshold Model in Dynamic Panels [PDF]

open access: yes
We adopt the threshold model of myopic cigarette addiction to US state-level panel data. The threshold model is used to identify the structural effects of cigarette demand determinants across the income stratification.

Finding novel vulnerabilities of hypomorphic BRCA1 alleles

open access: yesMolecular Oncology, EarlyView.
Synthetic lethality screens performed to identify novel vulnerabilities often model complete gene loss, thereby overlooking patient‐derived hypomorphic mutations. In this study, we have performed genome‐wide CRISPR screens on BRCA1 hypomorphic mutations, showing BRCA1I26A behaves like wild‐type, while BRCA1R1699Q mimics deficiency. Furthermore, we have

Natural Disasters and Development Thresholds: Infrastructure, Nonlinearity, and Economic Resilience

open access: yesSystems
Natural disasters pose major challenges to economic development, yet empirical evidence on their growth effects remains mixed. This study examines whether the macroeconomic impact of disasters depends on infrastructure development, using electricity ...
