Infra-red emission from classical novae [PDF]
International Astronomical Union Colloquium, 1990 During the evolution of a classical nova outburst, there are four times at which a significant infra-red (IR) flux is expected. The first Isothermal Dust Phase has been observed in a number of novae and analyses of this phase give valuable information on the properties of the emitting dust.

Advanced Science, EarlyView.A programmable passive digital shutter based on multiphase liquid–liquid interface dynamics is introduced for precise fabrication of hydrogel microfibers. By modulating the shutter operation, microfibers with tunable geometry—including linear, helical, tadpole‐like, and spherical forms—are produced.

Millinovae: A New Class of Transient Supersoft X-Ray Sources without a Classical Nova Eruption
The Astrophysical Journal LettersSome accreting binary systems containing a white dwarf (such as classical novae or persistent supersoft sources) are seen to emit low-energy X-rays with temperatures of ∼ 10 ^6 K and luminosities exceeding 10 ^35 erg s ^−1 .

Explosive lithium production in the classical nova V339 Del (Nova Delphini 2013)
, 2015 The origin of lithium (Li) and its production process have long been an unsettled question in cosmology and astrophysics. Candidates environments of Li production events or sites suggested by previous studies include big bang nucleosynthesis ...

The Cyclic Evolution of Classical Novae [PDF]
International Astronomical Union Colloquium, 1990 The cyclic evolution of classical novae (CN) cannot be observed, as in the case of recurrent or dwarf novae. The duration of a typical cycle may range from a few thousand to a few 105 years. Thus we have to rely on theoretical studies for understanding the periodic outbursts — due to thermonuclear runaways (TNR) — on the surface of accreting white ...

Advanced Science, EarlyView.IR‐induced dysbiosis depletes P. coprophilus and its metabolite 6‐methyluracil, leading to disinhibition of the IDO1‐Kyn‐AHR axis. This results in sustained fibroblast activation and collagen deposition, driving radiation induced intestinal fibrosis. ABSTRACT Therapeutic options for radiation‐induced intestinal fibrosis (RIF) remain limited. This study

The Astrophysical JournalThe evolution of cataclysmic variables (CVs) is driven by period changes ( $\dot{P}$ ), for which the long-venerable consensus is the magnetic braking model (MBM).

Orbital eccentricity in classical novae [PDF]
Nature, 1987 The effect on the orbital parameters of a classical nova of the ejection of mass during the nova explosion is considered. The most easily observable consequence is the generation of a small eccentricity in the orbit which leads to a luminosity modulation at a period just longer than the orbital period.

Advanced Science, EarlyView.Regulatory T cells (Tregs) suppress antitumor immunity. This study identifies that the translation scaffold DAP5/eIF4G2 is upregulated in tumor‐infiltrating Tregs (ti‐Tregs). DAP5 mediates an alternate translation mode to sustain CD25 and MCL‐1 expression, which is critical for ti‐Treg stability and survival in the tumor microenvironment.
