Redefining effective distance using multi-hop flows in urban mobility networks
Journal of Physics: ComplexityEffective distance, a concept that redefines spatial connectivity by considering human mobility links rather than physical distance, has proven to be a powerful tool for predicting epidemic spread.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Effective formulas for the Carath�odory distance
Manuscripta Mathematica, 1988 The authors are interested in computing the Carathéodory pseudodistance \(c_ G(0,z)\) from the center 0 of a balanced (i.e., complete circular) domain of holomorphy G in \({\mathbb{C}}^ n\) to a point \(z\in G\). When G is convex these distances are given by the well-known formula \[ c_ G(0,z)=\tanh^{-1} \inf \{\lambda >0:\quad z\in \lambda G\}, \] but

Molecular Oncology, EarlyView.Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Molecular Oncology, EarlyView.We developed and validated a DNA methylation–based biomarker panel to distinguish pleural mesothelioma from other pleural conditions. Using the IMPRESS technology, we translated this panel into a clinically applicable assay. The resulting two classifier models demonstrated excellent performance, achieving high AUC values and strong diagnostic accuracy.

E-readiness of open and distance learning (ODL) facilitators: Implications for effective mediation
Perspectives in Education, 2014 This article is a narrative report of the findings from the analysis of multicultural facilitators’ discourses on their e-readiness in the use of information and communication technologies (ICTs) affordances in open and distance learning (ODL) mediation

An Energy Trace Compression Method for Differential Power Analysis Attack
IEEE Access, 2020 Differential power analysis attacks are the most commonly used means to break cryptographic devices within the side-channel attack technology. Since there is a lot of noise in the energy trace of cryptographic devices, a large number of energy traces are

Molecular Oncology, EarlyView.We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.
