Multiport network analyzer self-calibration: a new approach and some interesting results [PDF]
A new approach to multiport network analyzer calibration is here presented. This solution exploits the redundancy of multiple standards connections in order to perform a multiport self-calibration.

First measurement results of a new highly-accurat SAR calibration target
The requirements on new spaceborne synthetic aperture radar (SAR) missions are always pushed towards better image quality with respect to signal-to-noise ratio, radiometric accuracy, and spatial resolution.

Statistical calibration: a simplification of Foster’s proof [PDF]
Foster (1999) has given a proof of the Calibration Theorem of Foster and Vohra (1998), using the Approachability Theorem proposed by Blackwell (1956).

We present a new bound for the worldvolume actions of branes with a Wess-Zumino term. For this we introduce a generalization of calibrations for which the calibration form is not closed. We then apply our construction to find the M-5-brane worldvolume solitons in an AdS background that saturate this bound.

Uncovering G Protein‐Coupled Receptors: Novel Targets and Biomarkers for Predicting Glioma Prognosis
ABSTRACT Background Low‐grade gliomas (LGG) exhibit significant heterogeneity and recurrence risk. G protein‐coupled receptors (GPCR) contribute to glioma malignant progression, but their prognostic value remains unclear. This work attempts to formulate a GPCR‐based outcome‐predicting model for LGG. Methods Based on TCGA LGG data, the enrichment scores

Abstract Multivariate regression is concerned with the relationship between two sets of variables. The two sets of variables are treated asymmetrically. The response set is regarded as random and the explanatory set treated as if it is fixed, even though in reality both may be random.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐
