Introduction: Travelers have poorer health than the general population due to more precarious living conditions. In France, there are no epidemiological studies on Travelers, accentuating their invisibility in public health policy and planning. Discrimination against them, their distrust of the state and institutions, and their non-prioritization of health were the reasons for a participatory research project on Travelers’ health status.

Optical coherent combining of high-power optical amplifiers for free-space optical communications.

Highly efficient coherent beam combining (CBC) of two very-high-power optical amplifiers (VHPOA) with applications to long-range FSO communications such as ground-to-space feeder links is presented. The CBC setup is designed to minimize the telecom signal degradation, with a polarization beam splitter used to minimize the power fluctuations and to control the output polarization state of the beam. The system delivers 80 W output power and is proven to be compatible with 25 Gb/s telecom signals with a less than 1 dB power penalty.

The use of observation has refined the development of our care practices. Its application in different intervention measures has shown us the importance of focusing on small matters. The value we place on them is for the child.

Measuring the cophasing state of a segmented mirror with a wavelength sweep and a Zernike phase contrast sensor.

The demand for higher resolution telescopes leads to segmented primary mirrors that need to be phased for operation. A phasing sensor applying a wavelength sweep technique provides a large capture range without modulating the position of individual mirror segments. This technique offers the potential to monitor the phasing state of a segmented telescope in parallel to the science observations.

Searching for phylogenetic patterns of Symbiodiniaceae community structure among Indo-Pacific Merulinidae corals.

Over half of all extant stony corals (Cnidaria: Anthozoa: Scleractinia) harbour endosymbiotic dinoflagellates of the family Symbiodiniaceae, forming the foundational species of modern shallow reefs. However, whether these associations are conserved on the coral phylogeny remains unknown. Here we aim to characterise Symbiodiniaceae communities in eight closely-related species in the genera , and and determine if the variation in endosymbiont community structure can be explained by the phylogenetic relatedness among hosts.
