Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Density variations of meteor flux along the Earth's orbit [PDF]

No model of distribution of meteor substance is known to explain the observed diurnal and annual variations of meteor rates, if that distribution is assumed to be constant during the year.

Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.

Sidereal anisotropies in the median rigidity range 60-600GV in 1978-1983 [PDF]

Observed sidereal variations are corrected for the influence of spurious variation by a method using the antisidereal diurnal variations produced from the same 2nd order anisotropy (Nagashima, et al., 1983).

Sampling Biases in Daily Average Temperatures From Greenland Climate Records

International Journal of Climatology, EarlyView.
Biases are introduced in the calculation of daily average temperatures due to uneven sampling times for the investigated weather station network in Greenland. The figure shows the network, an example of a daily temperature cycle with daily averages based on all or only two observations and an overview of how the number of observations per day changes ...

How Well Is Surface Diurnal Temperature Range Represented by Observations at 2‐m Level

International Journal of Climatology, EarlyView.
We demonstrate that geostationary satellites depict well the Diurnal Temperature Range (DTR) in the US but differ from information at 2 m level from model outputs. Upper: mean diurnal temperature range (DTR) using GOES‐E based land surface temperature (LST) for January (left) and July (right) during 2004–2009. Lower: mean diurnal temperature range (DTR)

The optimization of self-phased arrays for diurnal motion tracking of synchronous satellites [PDF]

The diurnal motion of a synchronous satellite necessitates mechanical tracking when a large aperture, high gain antenna is employed at the earth terminal.

Performance Evaluation of the MPAS Model in Simulating Southeast Asian Rainfall Characteristics

International Journal of Climatology, EarlyView.
This study evaluates the performance of the Model for Prediction Across Scales–Atmosphere (MPAS) in reproducing key rainfall characteristics over Southeast Asia (SEA) during 2000–2020, using the MSWEP dataset as reference. MPAS realistically captures the observed meridional rainfall gradient, with higher rainfall in the south and lower in the north, as

Seasonal Characteristics of Mesoscale Convective Systems Over the Philippines

International Journal of Climatology, EarlyView.
This study examines how mesoscale convective systems (MCSs) over the Philippines are most frequent during boreal summer, while those in winter are longer‐lived and more intense due to cold surges and enhanced easterly moisture transport. Intraseasonal oscillations, such as the Madden‐Julian Oscillation (MJO) and the Boreal Summer Intraseasonal ...

Comparative study of the phase of diurnal anisotropy on quiet and disturbed days on a long term basis up to recent period [PDF]

The data from the world wide grid of neutron monitoring stations was analyzed for a comparative study of the phase of diurnal anisotropy on quiet and disturbed days on a long term basis up to recent period.
