Outage diversity of MIMO block-fading channels with causal channel state information

, 2010
We study the outage diversity of the multiple-input multiple-output (MIMO) Rayleigh block-fading channel when causal channel state information (CSI) is available at the transmitter (CSIT). Within this setting, we consider the optimal power allocation for

Transcriptional profiling of circulating extracellular vesicles from prebiopsy prostate cancer patients

Molecular Oncology, EarlyView.
RNA profiling of circulating extracellular vesicles (EVs) from blood samples of men undergoing prostate biopsy identifies transcripts associated with clinically significant prostate cancer. Integrative analysis with public tumor datasets links EV‐derived gene signatures to tumor stage and progression‐free survival, highlighting CASP3, XRCC2, and RIT1 ...

Quantifying coupling and causality in dynamic bivariate systems: a unified framework for time-domain, spectral, and information-theoretic analysis

Frontiers in Network Physiology
Understanding the underlying dynamics of complex real-world systems, such as neurophysiological and climate systems, requires quantifying the functional interactions between the system units under different scenarios.

Measurement, theory, and information

Information and Control, 1979
ReferencesA general scheme is presented for explaining the inter-relation of measurement, theory, and information. Ordinary measurement theory is enriched with ideas from quantum physics and coupled to the concept of informations on lattices. Algebraic properties of the class of informations are studied, and it is shown that probability theories are ...

On the interplay between Shannon's information measures and reliability criteria

, 2009
In the literature, different reliability criteria are used in different coding theorems. Weak secrecy and strong secrecy are frequently used in information-theoretic security problems and their implications in terms of the average symbol error ...

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Smart Summary: A Distributed Medical Recommender System for Patients in the ICU Using Neural Networks

IEEE Access
In the medical domain, particularly in intensive care units (ICUs), the immense volume of patient data presents a significant challenge for clinicians, often resulting in the oversight of critical information or excessive time consumption in accessing it.

ESR1 methylation and ESR1 mutations in circulating tumor cells (CTCs) and paired plasma‐cfDNA of advanced breast cancer patients: A feasibility proof‐of‐concept study

Molecular Oncology, EarlyView.
Circulating tumor cells (CTCs) and plasma cell‐free DNA (cfDNA) were analyzed to detect ESR1 mutations and methylation in patients with advanced breast cancer. CTC‐derived DNA showed higher sensitivity for mutation detection and revealed complementary genetic and epigenetic alterations, highlighting the added value of CTC analysis for understanding ...

Early thrombus detection in ECMO with optimized impedance measurements: A simulative study

Journal of Electrical Bioimpedance
Extracorporeal oxygenation supports patients with severe cardiac or respiratory failure, with the oxygenator providing critical gas exchange. Thrombus formation in the oxygenator can impair efficiency and increase risks such as hemolysis and embolism ...

Possible applications of information theory in logistics

, 2011
Some ideas are presented how methods from information theory might be applied to logistics, more exactly to RFID security problems. Identification codes might be useful in a nosiy environment. Network coding could help in encryption and authentification.
