Earth Matter Effect in 7Be Solar Neutrino Experiments [PDF]

open access: yes, 1999
We determine the sensitivity of the KamLAND and Borexino experiments to the neutrino regeneration effect in the Earth as a function of Delta m^2 and theta, using realistic numbers for the signal and background rates.

A Forgotten Victory: Courcelette, 15 September 1916 [PDF]

open access: yes, 2012
The 2nd Canadian Division, which landed in France on 15 September 1915, had established an uncertain operational record by the summer of 1916. As part of the Canadian Corps, the division had spent virtually all of its time in or near Belgium’s notorious ...

Tuning the Electronic Structure and Spin State of Fe─N─C Catalysts Using an Axial Oxygen Ligand and Fe Clusters for High‐Efficiency Rechargeable Zinc–Air Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A FeN4─O/Clu@NC‐0.1Ac catalyst containing atomically‐dispersed FeN4─O sites (medium‐spin Fe2+) and Fe clusters delivered a half‐wave potential of 0.89 V for ORR and an overpotential of 330 mV at 10 mA cm−2 for OER in 0.1 m KOH. When the catalyst was used in a rechargeable Zn–air battery, a power density of 284.5 mW cm−2 was achieved with excellent ...

Study on the Optimization Path of After-school Physical Education Services in Junior High Schools under the Policy of Increasing the Physical Education Score of the Secondary School Examination [PDF]

open access: yesSHS Web of Conferences
In the context of the increase in the value of physical education scores in the midterm examination, there is an undesirable phenomenon of “jumping the gun” in physical education, and the rapid expansion of extracurricular training institutions in ...

Bridging the Gap: Canadian Engineer Operations at Canal du Nord–Bourlon Wood, 1918 [PDF]

open access: yes, 2019
During the last hundred days of the Great War, the Allied armies swept eastward past the Hindenburg Line with hammer-blow offensive warfare. Performing their work under intense machine gun and shell fire, engineers erected bridges and constructed roads ...

Operando Temperature Sensing at the Actual Electrocatalytic Interface by Nanodiamond Quantum Sensors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating a wide‐field microscope with a custom‐designed electrolyzer, nanoscale temperature changes can be recorded in situ during the electrolysis process without interfering with ongoing electrochemical reactions. This method establishes a correlation between the interface temperature and specific electrochemical reactions, making the measured ...

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics

open access: yesAdvanced Materials, EarlyView.
Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Premises for Reforming the Regulation of Securities Offerings: An Essay [PDF]

open access: yes, 2000
Cox discusses six fundamental tenets that should guide the regulation of public offerings of securities. It is assumed that regulation is to be re-examined from the ground up, with no political or regulatory ...

Heterogeneous Integration of Flipped Oxide Heterostructure Membranes for Nanoelectronics

open access: yesAdvanced Electronic Materials, EarlyView.
A flipped electronically reconfigurable STO/LAO freestanding membrane is demonstrated and integrated with various host platforms via controlled transfer. Using ultra‐low‐voltage electron‐beam lithography, conductive nanostructures are created at the buried STO/LAO interface. This novel approach enables heterogeneous integration of flipped complex oxide
