Cellular system information capacity change at higher frequencies due to propagation loss and system parameters [PDF]

, 2012
In this paper, mathematical analysis supported by computer simulation is used to study cellular system information capacity change due to propagation loss and system parameters (such as path loss exponent, shadowing and antenna height) at microwave ...

Association of CDKN2A/B Homozygous Deletion and Extent of Resection With Survival of Patients With WHO CNS5 Grade 4 Astrocytoma

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives WHO grade 4 astrocytomas are associated with poor prognosis, and their prognostic factors remain controversial. This study aimed to identify the prognostic factors and develop a management algorithm for these patients. Methods This study retrospectively included 151 CNS5 adult grade 4 astrocytomas from two medical centers.

Breakpoint-specific multiplex polymerase chain reaction allows the detection of IKZF1 intragenic deletions and minimal residual disease monitoring in B-cell precursor acute lymphoblastic leukemia

Haematologica, 2013
Deletion of the Ikaros (IKZF1) gene is an oncogenic lesion frequently associated with BCR-ABL1-positive acute lymphoblastic leukemias. It is also found in a fraction of BCR-ABL1-negative B-cell precursor acute lymphoblastic leukemias, and early studies ...

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.

MATCHCLIP: Locate precise breakpoints for copy number variation using CIGAR string by matching soft clipped reads

Frontiers in Genetics, 2013
Copy number variations (CNVs) are associated with many complex diseases. Next generation sequencing data enable one to identify precise CNV breakpoints to better under the underlying molecular mechanisms and to design more efficient assays.

A Reappraisal of Ventilatory Thresholds in Wheelchair Athletes With a Spinal Cord Injury: Do They Really Exist?

Frontiers in Physiology, 2021
The ventilatory threshold (VT) separates low- from moderate-intensity exercise, the respiratory compensation point (RCP) moderate- from high-intensity exercise. Both concepts assume breakpoints in respiratory data. However, the objective determination of

Learning smoothing models of copy number profiles using breakpoint annotations

BMC Bioinformatics, 2013
Many models have been proposed to detect copy number alterations in chromosomal copy number profiles, but it is usually not obvious to decide which is most effective for a given data set.

Beyond Presumptions: Toward Mechanistic Clarity in Metal‐Free Carbon Catalysts for Electrochemical H2O2 Production via Data Science

Advanced Materials, EarlyView.
Metal‐free carbon catalysts enable the sustainable synthesis of hydrogen peroxide via two‐electron oxygen reduction; however, active site complexity continues to hinder reliable interpretation. This review critiques correlation‐based approaches and highlights the importance of orthogonal experimental designs, standardized catalyst passports ...

Catastrophic chromosomal restructuring during genome elimination in plants. [PDF]

, 2015
Genome instability is associated with mitotic errors and cancer. This phenomenon can lead to deleterious rearrangements, but also genetic novelty, and many questions regarding its genesis, fate and evolutionary role remain unanswered.

Multi‐Material Gradient Printing Using Meniscus‐enabled Projection Stereolithography (MAPS)

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
MAPS is a new vat‐free printing technique that utilizes programmed delivery of resin droplets with custom formulations to enable multi‐material gradient printing of 3D structures with user‐defined variations in mechanical stiffness, opacity, surface energy, cell densities, and magnetic properties. Abstract Light‐based additive manufacturing methods are
