Isocitrate Dehydrogenase Mutations in Cancer: From Bench to Bedside Applications

MedComm, Volume 7, Issue 5, May 2026.
Mutant isocitrate dehydrogenase affects multiple cancer types. Alterations in IDH1 and IDH2 result in abnormal enzyme activity, leading to the overproduction of D‐2‐hydroxyglutarate (D‐2HG). This metabolite disrupts cellular metabolism and epigenetic regulation, driving cancer initiation, progression, and metastasis.

Adaptive Non-myopic Quantizer Design for Target Tracking in Wireless Sensor Networks

, 2013
In this paper, we investigate the problem of nonmyopic (multi-step ahead) quantizer design for target tracking using a wireless sensor network. Adopting the alternative conditional posterior Cramer-Rao lower bound (A-CPCRLB) as the optimization metric ...

Simultaneous Detection of GABA and Glycine Using MEGA‐PRESS With TE Optimization at 3T

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2479-2488, May 2026.
ABSTRACT Purpose To achieve the simultaneous acquisition of gamma‐aminobutyric acid (GABA) and glycine (Gly) using a MEGA‐PRESS sequence with an optimized TE at 3T. Methods MEGA‐PRESS simulations were performed at TEs 60‐88 ms to determine the optimal TE for Gly detection with minimal myo‐Inositol (mI) overlap and maximal GABA detection sensitivity ...

Repeatability of Rapid Human Cardiac Phosphorus MRSI (31P‐MRSI) Using Concentric Ring Trajectory Readouts at 7 T

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2508-2514, May 2026.
ABSTRACT Purpose PCr/ATP ratio is determined at 7 T typically using Fourier‐transform based magnetic resonance spectroscopic imaging sequences (FT‐MRSI). These sequences require acquisition times longer than desirable for inclusion in cardiac clinical trials. Concentric ring trajectory (CRT‐MRSI) has been described as an accelerated alternative k‐space

Parameter estimation from Gravitational waves generated by non-spinning binary black holes with laser interferometers: beyond the Fisher information

, 2010
In this paper we apply to gravitational waves from non-spinning binary systems a recently intro- duced frequentist methodology to calculate analytically the error for a maximum likelihood estimate (MLE) of physical parameters.

On the attainment of the Wasserstein--Cramer--Rao lower bound

Information Geometry
Recently, a Wasserstein analogue of the Cramer--Rao inequality has been developed using the Wasserstein information matrix (Otto metric). This inequality provides a lower bound on the Wasserstein variance of an estimator, which quantifies its robustness against additive noise.
