Holographic Weyl anomaly for GJMS operators: one Laplacian to rule them all
(2019-02-27)The holographic Weyl anomaly for GJMS operators (or conformal powers of the Laplacian) are obtained in four and six dimensions. In the context of AdS/CFT correspondence, free conformal scalars with higher-derivative kinetic ... -
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) III. Atmospheric structure of the misaligned ultra-hot Jupiter WASP-121b
(2020-04)Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present the analysis of new optical spectroscopy ... -
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS): IV. A spectral inventory of atoms and molecules in the high-resolution transmission spectrum of WASP-121 b
(2020-09-18)Context. WASP-121 b is a hot Jupiter that was recently found to possess rich emission (day side) and transmission (limb) spectra, suggestive of the presence of a multitude of chemical species in the atmosphere. Aims. ... -
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS)? V. Detection of sodium on the bloated super-Neptune WASP-166b
(2020-07-06)Planet formation processes or evolution mechanisms are surmised to be at the origin of the hot Neptune desert. Studying exoplanets currently living within or at the edge of this desert could allow disentangling the respective ... -
How do chilean pre-service teachers correct errors in writing?
(2018-06)Most research on error correction has dealt with feedback strategies used in the classroom and the effect of these strategies on students’ performance. However, not much research has been conducted on pre-service teachers’ ... -
How do spatiotemporal parameters and lower-body stiffness change with increased running velocity? a comparison between novice and elite level runners
(2019-11)This study aimed to examine the effect of running velocity on spatiotemporal parameters and lower-body stiffness of endurance runners, and the influence of the performance level on those adaptations. Twenty-two male runners ... -
How do the ownership structure and board of directors' features impact earnings management? the spanish case
(2020-01-07)This paper examines how the ownership structure and board of directors' features determine the managerial opportunistic behavior exemplified in the management of accounting earnings. This study contributes to the literature ... -
How does anxiety caused by the use of oral English influence teachers of English as a Foreign Language in Chilean classrooms?
(2017)There are diverse studies about the relationship between anxiety and the use of oral English; nonetheless, the majority of them are focused on students rather than teachers. The main purpose of this study is to gather ... -
How long is required to undertake step variability analysis during running? A pilot study
(2019-03-04)BACKGROUND: The accurate assessment of step variability remains problematic. OBJECTIVE: To determine the minimum time required for assessing spatiotemporal variability during continuous running. METHODS: Seventeen endurance ... -
How much do network support and managerial skills affect women’s entrepreneurial success? The overlooked role of country economic development
(2021)The success of women-owned businesses with regard to the stages of economic development of countries is under-examined on a global basis. This study explores the relationship between country economic and political contexts ... -
How parasites divide resources: a test of the niche apportionment hypothesis
(2003)Modelling species abundance patterns, i.e. the distribution of relative abundance among species within the same community, has become a common framework in community ecology. To describe species abundance patterns several ... -
How to Measure Organic Fruit Consumer Behavior: A Systematic Review
(2022)This review article seeks to systematically identify appropriate ways to measure the consumption behavior of organic fruits. The systematic review of the literature was performed according to the criteria of the Preferred ... -
Hydrodynamic effects of use of eductors (Jet-Mixing Eductor) for water inlet on circular tank fish culture
(2014)Trials were conducted in circular tanks used in aquaculture (1.2 m diameter and 0.4 of useful depth) in order to evaluate the effect of different water injection devices on the tangential velocity of the water, its uniformity ... -
Hydrodynamics of a river-associated tidalinletand maintenance ofdynamic equilibrium: preliminary findings
(2014)Detailed video images and ADCP measurementswere used to describe the processes of suspended sediment transport by the Mataquito River into the Pacific Ocean. It is found that, in the absence of ... -
Hydrological connectivity drives longitudinal movement of endangered endemic Chilean darter Percilia irwini (Eigenmann, 1927)
(2021)Movement is a fundamental aspect of fish ecology, and it therefore represents an important trait to monitor for the management and conservation of fish populations. This is especially true for small benthic fish, as they ... -
Hydrological droughts in the southern Andes (40–45°S) from an ensemble experiment using CMIP5 and CMIP6 models
(2021)The decrease in freshwater input to the coastal system of the Southern Andes (40–45°S) during the last decades has altered the physicochemical characteristics of the coastal water column, causing significant environmental, ... -
Hyperspectral imaging retrieval using MODIS satellite sensors applied to volcanic ash clouds monitoring
(2019)In this paper, we present a method for hyperspectral retrieval using multispectral satellite images. The method consists of the use of training spectral data with a compressive capability. By using principal component ... -
