Direct and transgenerational effects of an experimental heatwave on early life stages in a freshwater snail
(Wiley-Blackwell Publishing Ltd., 2019)
Global climate change imposes a serious threat to natural populations of many species. Estimates of the effects of climate change‐mediated environmental stresses are, however, often based only on their direct effects on ...
Direct determination of the atomic mass difference of the pairs 76As−76Se and 155Tb−155Gd rules out 76As and 155 Tb as possible candidates for electron (anti)neutrino mass measurements
(American Physical Society (APS), 2022)
The first direct determination of the ground-state–to–ground-state Q values of the β− decay 76As→76Se and the electron-capture decay 155Tb→155Gd was performed utilizing the double Penning trap mass spectrometer JYFLTRAP. ...
Direct determination of the excitation energy of the quasistable isomer 180mTa
(American Physical Society (APS), 2022)
180mTa is a naturally abundant quasistable nuclide and the longest-lived nuclear isomer known to date. It is of interest, among others, for the search for dark matter, for the development of a γ laser, and for astrophysics. ...
Direct Ionization Impact on Accelerator Mixed-Field Soft Error Rate
(Institute of Electrical and Electronics Engineers, 2020)
We investigate, through measurements and simulations, the possible direct ionization impact in the accelerator soft error rate, not considered in standard qualification approaches. Results show that, for a broad variety ...
Direct mass measurements on neutron-deficient xenon isotopes with the ISOLTRAP mass spectrometer
(Elsevier; North-Holland, 2002)
The masses of Xe isotopes with 124 A 114 have been measured
using the ISOLTRAP spectrometer at the on-line mass separator
ISOLDE/CERN. A mass resolving power of 500000 was chosen resulting in an accuracy of m 12 ...
Direct measurement of the mass difference of 72As−72Ge rules out 72As as a promising β-decay candidate to determine the neutrino mass
(American Physical Society (APS), 2021)
We report the first direct determination of the ground-state to ground-state electron-capture Q value for the 72As to 72Ge decay by measuring their atomic mass difference utilizing the double Penning trap mass spectrometer, ...
Direct observation of a borane–silane complex involved in frustrated Lewis-pair-mediated hydrosilylations
(Nature Publishing Group, 2014)
Perfluorarylborane Lewis acids catalyse the addition of silicon–hydrogen bonds across C=C, C=N and C=O double bonds. This ‘metal-free’ hydrosilylation has been proposed to occur via borane activation of the silane Si–H ...
Direct observation of the Ba 114 →Xe 110 →Te 106 →Sn 102 triple α -decay chain using position and time correlations
(American Physical Society, 2016)
The triple α-decay chain 114Ba → 110Xe → 106Te → 102Sn has been directly observed for the first time,
following the 58Ni(58Ni ,2n) reaction. Implantation of 114Ba nuclei into a double-sided silicon-strip detector has
allowed ...
Direct observation of the dead-cone effect in quantum chromodynamics
(Nature Publishing Group, 2022)
In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of ...
Direct pathway cloning and expression of the radiosumin biosynthetic gene cluster
(Royal Society of Chemistry (RSC), 2023)
Radiosumins are a structurally diverse family of low molecular weight natural products that are produced by cyanobacteria and exhibit potent serine protease inhibition. Members of this family are dipeptides characterized ...
