Communication-Efficient Federated Swarm Learning for SAG-CM on Heterogeneous Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Federated learning (FL) enables multiple clients to collaboratively train models without sharing private data, but it often struggles under non-IID distributions and tight edge budgets—particularly in systems, such as space–air– ...

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Covert communication using skewed alpha-stable distributions

, 2015
A covert communication system using a random carrier having skewed alpha-stable distribution is introduced. The proposed method utilises the random signals with skewed alpha-stable distributions exhibiting antipodal characteristics to encode the binary ...

Gut microbiota alterations in patients with non‐small‐cell lung cancer undergoing chemoradiotherapy

Molecular Oncology, EarlyView.
We investigated the impact of concurrent chemoradiotherapy (CRT) on the gut microbiota in patients with locally advanced non‐small‐cell lung cancer. Overall gut microbiota composition remained largely stable throughout CRT while antibiotic exposure may influence microbial diversity.

Parameters estimation of the alpha-stable distribution and applications to financial data

Chilean Journal of Statistics
Summary: This article introduces a generalized method for estimating parameters of an alphastable distribution based on the characteristic function. We propose a novel approach that extends existing techniques. As an application, we compare our proposed method with the maximum likelihood method.

Heavy-tailed distributions in VaR calculations [PDF]

The essence of the Value-at-Risk (VaR) and Expected Shortfall (ES) computations is estimation of low quantiles in the portfolio return distributions.

Multistable processes and localizability [PDF]

, 2012
We use characteristic functions to construct alpha-multistable measures and integrals, where the measures behave locally like stable measures, but with the stability index alpha(x) varying with x.

Regulation of the lncRNA NEAT1 by p53‐ΔNp63 crosstalk modulates the DNA damage response and therapeutic efficacy in HNSCC

Molecular Oncology, EarlyView.
In head and neck squamous cell carcinoma (HNSCC) p53 and p63 exert opposite roles on the transcription regulation of the lncRNA NEAT1. Under basal conditions, p53 levels are low and p63 represses NEAT1 expression. Upon genotoxic stress, p53 is rapidly induced, displacing p63 from the NEAT1 promoter leading to NEAT1 transcriptional activation and ...

Indirect estimation of elliptical stable distributions [PDF]

We present an indirect estimation approach for elliptical stable distributions which relies on the use of a multivariate t distribution as auxiliary model.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.
