Model based methodology development for energy recovery in ash heat exchange systems [PDF]

open access: yes, 2010
Flash tank evaporation combined with a condensing heat exchanger can be used when heat exchange is required between two streams and where at least one of these streams is difficult to handle (in terms of solid particles content, viscosity, pH ...

Discovery of Blue Hook Stars in the Massive Globular Cluster M54

open access: yes, 2003
We present BV photometry centered on the globular cluster M54 (NGC 6715). The color-magnitude diagram clearly shows a blue horizontal branch extending anomalously beyond the zero age horizontal branch theoretical models.

Temperature‐Dependent Zinc Oxide Cathodoluminescence: Toward Compact Wavelength‐Tunable Solid‐State Photoionization Sources

open access: yesAdvanced Optical Materials, EarlyView.
A proof‐of‐concept of a thermally‐tunable cathodoluminescence‐based light source is demonstrated using a wide‐bandgap z‐cut ZnO crystal as anode, resulting in the ultraviolet (UV) emission peak shifting from 398 nm to ~409 nm (3.115‐3.032 eV). Our results establish the feasibility of a compact, field‐deployable UV source with potential for gas sensing ...

An average update frequency based NAND flash garbage collection algorithm

open access: yesDianzi Jishu Yingyong, 2019
Aiming at the unique properties of NAND flash, an average update frequency based NAND flash garbage collection algorithm is proposed. Firstly, the victim block selection strategy based on invalid page age sum is adopted.

Hot Flash: Lima Branch Ohio State University [PDF]

open access: yes, 1971
The Ohio State University has digitized some of its historically significant content for use by scholars, students and the public. These materials should be examined as part of the historical record.

Genomics Insights Into High‐Latitude Adaptation of Tibetan Macaques

open access: yesAdvanced Science, EarlyView.
Tibetan macaques exhibit unique adaptations to cold, high‐latitude environments, including shortened tails and enhanced fat storage. Genomic analyses reveal a species‐specific TBX6 mutation linked to tail reduction and selection on lipid metabolism genes.

Hydrodynamic simulations of shell convection in stellar cores

open access: yes, 2011
Shell convection driven by nuclear burning in a stellar core is a common hydrodynamic event in the evolution of many types of stars. We encounter and simulate this convection (i) in the helium core of a low-mass red giant during core helium flash leading

Electrochemiluminescence Drives Photodynamic Therapy In Vivo

open access: yesAdvanced Science, EarlyView.
Electrochemiluminescence (ECL)‐driven photodynamic therapy (PDT) for in vivo cancer treatment is reported for the first time. The flexible ECL patch exhibits stable and intense luminance under alternating current voltage, enabling efficient photosensitization to generate reactive oxygen species that damage cancer cells, thus leading to significant ...

Nucleosynthesis of Elements in Low to Intermediate Mass Stars through the AGB Phase

open access: yes, 1997
We present a review of the main phases of stellar evolution with particular emphasis on the nucleosynthesis and mixing mechanisms in low- and intermediate-mass stars. In addition to explicit studies of the effects of the first, second and third dredge-up,

Ir(III) Complexes Convert Cold to Hot Tumors via Ferroptosis/Necroptosis‐Driven Immunogenic Cell Death and Photosensitized CD47 Downregulation

open access: yesAdvanced Science, EarlyView.
Red‐light‐activated Ir1 overcomes hypoxia tolerance and adapts to the immunosuppressive tumor microenvironment, converting immunologically cold tumors into inflamed hot microenvironments. This conversion is driven by synergistic induction of immunogenic cell death through coordinated ferroptosis‐necroptosis pathways and spatiotemporally controlled ...
