Solar Temporal Photon Bunching

open access: yes, 2018
Conventional ground-based astronomical observations suffer from image distortion due to atmospheric turbulence. Light from thermal blackbody radiators such as stars exhibits photon bunching behaviour at sufficiently short time-scales which should be ...

Fine‐Needle Aspiration of Salivary Gland Tumors With Low‐Grade Oncocytic Features: Focusing on Oncocytoma Versus Oncocytic Mucoepidermoid Carcinoma

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Salivary gland fine‐needle aspirates (FNAs) with low‐grade oncocytic features are diagnostically challenging due to the substantial morphologic overlap between benign oncocytic tumors and their malignant mimickers. This study evaluates the diagnostic discriminators, performance, and risk of malignancy of these lesions using the ...

Longitudinal painting with large amplitude second harmonic rf voltages in the rapid cycling synchrotron of the Japan Proton Accelerator Research Complex

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2009
In the rapid cycling synchrotron (RCS) of the Japan Proton Accelerator Research Complex (J-PARC), the longitudinal painting is important to alleviate the space-charge effects.

Epidemiology of Intensive Nutritional Interventions and Restraints in Hospitalizations for Anorexia Nervosa: Annual National Trends of the United States

open access: yesInternational Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Despite the clinical relevance of enteral and parenteral tube feeding and restraint use in anorexia nervosa (AN), national‐level data on their use have remained limited, particularly for total parenteral nutrition (TPN) and percutaneous endoscopic gastrostomy (PEG).

Bunching for Regions and Locations

open access: yesElectronic Notes in Theoretical Computer Science, 2006
AbstractThere are a number of applied lambda-calculi in which terms and types are annotated with parameters denoting either locations or locations in machine memory. Such calculi have been designed with safe memory-management operations in mind.It is difficult to construct directly denotational models for existing calculi of this kind.

Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal

Bunching phase and constraints on echo enabled harmonic generation

open access: yesPhysical Review Accelerators and Beams, 2018
A simple mathematical description is developed for the bunching spectrum in echo enabled harmonic generation (EEHG) that incorporates the effect of additional electron beam energy modulations. Under common assumptions, they are shown to contribute purely

Bunch by bunch feedback systems review

open access: yes
Bunch-by-bunch feedback systems have become essential components of high-energy particle accelerators, particularly for ultra-low emittance rings. These systems have been widely used in accelerator facilities to ensure beam quality and to apply them to extensions such as beam diagnostics or manipulation.

Step bunching with alternation of structural parameters [PDF]

open access: yes, 2003
By taking account of the alternation of structural parameters, we study bunching of impermeable steps induced by drift of adatoms on a vicinal face of Si(001).

Competing Charge Transport Pathways: A Spirobifluorene‐Based Molecular Loop

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A rigid molecular loop integrating a spirobifluorene (SBF) core with a cycloparaphenylene (CPP) moiety provides two distinct transport channels. Through‐space spiroconjugation and radial π‐conjugation along a CPP backbone coexist within a single molecule.
