Light comfort zones of mesopelagic acoustic scattering layers in two contrasting optical environments
(Peer reviewed; Journal article, 2016-07)We make a comparison of the mesopelagic sound scattering layers (SLs) in two contrasting optical environments; the clear Red Sea and in murkier coastal waters of Norway (Masfjorden). The depth distributions of the SL in ... -
Light conditions during Atlantic salmon embryogenesis affect key neuropeptides in the melanocortin system during transition from endogenous to exogenous feeding
(Journal article; Peer reviewed, 2023)During the first feeding period, fish will adapt to exogenous feeding as their endogenous source of nutrients is depleted. This requires the development of a functional physiological system to control active search for ... -
Light meson spectroscopy from Dalitz plot analyses of ηc decays to η0 K+K− , η0 π + π − , and ηπ + π − produced in two-photon interactions
(Journal article; Peer reviewed, 2021)We study the processes γγ→ηc→η′K+K−, η′π+π−, and ηπ+π− using a data sample of 519 fb−1 recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e+e− collider at center-of-mass energies at and near ... -
Light neutral meson production in heavy ion collisions with ALICE in the era of precision physics at the LHC
(Journal article; Peer reviewed, 2021)The production of light neutral mesons in AA collisions probes the physics of the Quark-Gluon Plasma (QGP), which is formed in heavy-ion collisions at the LHC. More specifically, the centrality dependent neutral meson ... -
Light penetration structures the deep acoustic scattering layers in the global ocean
(Peer reviewed; Journal article, 2017)The deep scattering layer (DSL) is a ubiquitous acoustic signature found across all oceans and arguably the dominant feature structuring the pelagic open ocean ecosystem. It is formed by mesopelagic fishes and pelagic ... -
Light scalars in the Weinberg 3HDM potential with spontaneous CP violation
(Journal article; Peer reviewed, 2022)The Z2×Z2-symmetric 3HDM potential, sometimes called Weinberg's 3HDM potential, can accommodate both explicit and spontaneous CP violation as well as natural flavour conservation and is hence relevant for studies of CP ... -
Light-quark and gluon jet discrimination in pp collisions at √s = 7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2014-08-21)A likelihood-based discriminant for the identification of quark- and gluon-initiated jets is built and validated using 4.7 fb−1 of proton–proton collision data at √s = 7 TeV collected with the ATLAS detector at the LHC. ... -
Lignin Preservation and Microbial Carbohydrate Metabolism in Permafrost Soils
(Journal article; Peer reviewed, 2022)Permafrost-affected soils in the northern circumpolar region store more than 1,000 Pg soil organic carbon (OC), and are strongly vulnerable to climatic warming. However, the extent to which changing soil environmental ... -
Likelihood Estimation of Jump-Diffusions. Extensions from Diffusions to Jump-Diffusions, Implementation with Automatic Differentiation, and Applications
(Master thesis, 2016-06-02)This thesis considers the problem of likelihood- based parameter estimation for time-homogeneous jump-diffusion processes. The problem is that there often is no analytic solution to the stochastic differential equations ... -
A Likelihood Ratio and Markov Chain-Based Method to Evaluate Density Forecasting
(Peer reviewed; Journal article, 2019)In this paper, we propose a likelihood ratio based method to evaluate density forecasts which can jointly evaluate the unconditional forecasted distribution and dependence of the outcomes. Unlike the well‐known Berkowitz ... -
LIME: Software for 3-D visualization, interpretation, and communication of virtual geoscience models
(Peer reviewed; Journal article, 2019-01-10)The use of three-dimensional (3-D), photo-textured representations of topography from laser scanning and photogrammetry is becoming increasingly common across the geosciences. This rapid adoption is driven by recent ... -
Limited evidence for species-specific sensitivity of temperature-dependent fractionation of oxygen stable isotope in biominerals: A meta-analysis
(Journal article; Peer reviewed, 2023)Water temperature is key to the study of aquatic ectotherm ecology, but precise measurements of individual-based thermal experience remain difficult to validate. The stable isotope composition of oxygen in biominerals acts ... -
Limited exchange between the deep Pacific and Atlantic oceans during the warm mid-Pliocene and Marine Isotope Stage M2 “glaciation”
(Journal article; Peer reviewed, 2023)The Piacenzian stage (3.6–2.6 Ma) of the Pliocene is the most recent period where Earth experienced sustained intervals of global warmth analogous to predicted near-future climates. Despite considerable efforts to characterize ... -
Limited Influence of Localized Tropical Sea-Surface Temperatures on Moisture Transport into the Arctic
(Journal article; Peer reviewed, 2021)Arctic moisture transport is dominated by planetary-scale waves in reanalysis. Planetary waves are influenced by localized Sea-Surface Temperature (SST) features such as the tropical warm pool. Here, an aquaplanet model ... -
Limited Link of Common Blood Parameters with Tinnitus
(Journal article; Peer reviewed, 2023)Background: Tinnitus severity is generally assessed by psychometric and audiological instruments. However, no objective measure exists to evaluate the subjective discomfort and suffering caused by this hearing phenomenon. ... -
Limited male incubation ability and the evolution of egg size in shorebirds
(Peer reviewed; Journal article, 2006-06-22)In bird species where males incubate but are smaller than females, egg size may be constrained by male body size, and hence ability to incubate the eggs. Using data from 71 such shorebird species, we show that egg size ... -
Limits on the production of the standard model Higgs boson in pp collisions at s=7 TeV with the ATLAS detector
(Peer reviewed; Journal article, 2011-09-20)A search for the Standard Model Higgs boson at the Large Hadron Collider (LHC) running at a centre-of-mass energy of 7 TeV is reported, based on a total integrated luminosity of up to 40 pb−1 collected by the ATLAS detector ... -

Lineage-level divergence of copepod glycerol transporters and the emergence of isoform-specific trafficking regulation
(Journal article; Peer reviewed, 2021)Transmembrane conductance of small uncharged solutes such as glycerol typically occurs through aquaglyceroporins (Glps), which are commonly encoded by multiple genes in metazoan organisms. To date, however, little is known ... -
The lineage-specific evolution of aquaporin gene clusters facilitated tetrapod terrestrial adaptation
(Peer reviewed; Journal article, 2014-11-26)A major physiological barrier for aquatic organisms adapting to terrestrial life is dessication in the aerial environment. This barrier was nevertheless overcome by the Devonian ancestors of extant Tetrapoda, but the origin ...
