Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

Strict Avalanche Criterion of SHA-256 and Sub-Function-Removed Variants

Cryptography
The measure of diffusion, the property of dissipating patterns and statistical structures in cryptographic transformations, serves as a valuable heuristic for assessing the obscurity of patterns that could lead to collisions.

Measurement and simulation of the impact of coherent synchrotron radiation on the Jefferson Laboratory energy recovery linac electron beam

Physical Review Special Topics. Accelerators and Beams, 2015
In an experiment conducted on the Jefferson Laboratory IR free-electron laser driver, the effects of coherent synchrotron radiation (CSR) on beam quality were studied.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Analysis of the cryptographic strength of the SHA-256 hash function using the SAT approach

Научно-технический вестник информационных технологий, механики и оптики
Cryptographic hash functions play a significant role in modern information security systems by ensuring data integrity and enabling efficient data compression. One of the most important and widely used cryptographic hash functions is SHA-256 that belongs

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Evaluation of abdominal compression band for pediatric postural tachycardia syndrome: a crossover study

Frontiers in Pediatrics
BackgroundAbdominal compression is an effective nonpharmacological treatment for orthostatic intolerance. Although the efficacy of abdominal compression bands has been studied in adults, studies involving children are limited. This study investigates the

Compression-aware pseudo-functional testing [PDF]

2009 International Test Conference, 2009
With technology scaling, the discrepancy between integrated circuits' activities in normal functional mode and that in structural test mode has an increasing adverse impact on the effectiveness of manufacturing test. By identifying functionally unreachable states in the circuit and avoiding them during the test generation process, pseudo-functional ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

The Text-Organizing Function of Compression in English Scientific Discourse

Armenian Folia Anglistika, 2016
English scientific discourse can be characterized as a key area of the economy principle realization in the form of text compression. The latter carries out a major text-organizing function due to its potential to form implicit meanings and ...
