Near-tropical subsurface ice on Mars [PDF]
Vincendon, M., J. Mustard, F. Forget, M. Kreslavsky, A. Spiga, S.
Murchie, and J.-P. Bibring (2010), Near-tropical subsurface ice on Mars,
Geophys. Res. Lett., 37, L01202, 2011 Near-surface perennial water ice on Mars has been previously inferred down to latitudes of about 45{\deg} and could result from either water vapor diffusion through the regolith under current conditions or previous ice ages precipitations. In this paper we show that at latitudes as low as 25{\deg} in the southern hemisphere buried water ice in the ...

Switching on Supramolecular DNA Junction Binding Using a Human Enzyme
Angewandte Chemie, EarlyView.Stimulus responsive control of DNA junction formation: Enzyme action cleaves flexible arms from a metallo‐supramolecular cylinder, transforming an inert metallo‐supramolecular structure into an active metallo‐supramolecular agent, and switching on its ability to assemble, bind and stabilize DNA three‐way junction structures.

Scaling behavior in the convection-driven Brazil-nut effect [PDF]
PRE 86, 050301(R) (2012), 2011 The Brazil-nut effect is the phenomenon in which a large intruder particle immersed in a vertically shaken bed of smaller particles rises to the top, even when it is much denser. The usual practice, while describing these experiments, has been to use the dimensionless acceleration \Gamma=a \omega^2/g, where a and \omega are respectively the amplitude ...

Energy cover crops for biogas production increase soil organic carbon stocks: A modeling approach
GCB Bioenergy, Volume 15, Issue 2, Page 224-238, February 2023., 2023 The anaerobic digestion of cover crops for biogas production does not compete directly with food production and is promoted in various countries. Some questions arose regarding the effects of energy cover crops on soil organic carbon (SOC) stocks.

Monte Carlo N-Particle simulations of an underwater chemical threats detection system using neutron activation analysis [PDF]
JINST 14 P0900 (2019), 2019 In this paper we present Monte Carlo N-Particle (MCNP) simulations of the system for underwater threat detection using neutron activation analysis developed in the SABAT project. The simulated system is based on a D-T neutron generator emitting 14~MeV neutrons without associated $\alpha$ particle detection and equipped with a LaBr$_3$:Ce scintillation ...

SPINDLY interacts with EIN2 to facilitate ethylene signalling‐mediated fruit ripening in tomato
Plant Biotechnology Journal, Volume 21, Issue 1, Page 219-231, January 2023., 2023 SlSPY regulates fruit ripening by changing the ethylene response in tomato. A central regulator of ethylene signaling SlEIN2 as a SlSPY interacting protein regulates fruit ripening. SlSPY as an O‐glycosylation enzyme promotes the stability and nuclear accumulation of SlEIN2. SlEIN2 is required for the function of SlSPY in fruit ripening.

Development and characterization of Brassica juncea fruticulosa introgression lines exhibiting resistance to mustard aphid [PDF]
, 2017 Background: Mustard aphid is a major pest of Brassica oilseeds. No source for aphid resistance is presently available in Brassica juncea . A wild crucifer, Brassica fruticulosa is known to be resistant to mustard aphid. An artificially synthesized amphiploid, AD-4 (B. fruticulosa x B. rapa var. brown sarson) was developed for use as a bridge species to
