man's own comrades?untrained men in all instances; and the practices were open to the gravest objections. The measure to ensure this humane and early relief now more or less introduced into all civilized armies is the formation of an Army Hospital Corps. The modern principle for the medical service of an army in the field is to separate the sick and wounded from the moving force, and to isolate...

The purpose of the Navigation Economic Technologies (NETS) research program is to develop a standardized and defensible suite of economic tools for navigation improvement evaluation. NETS addresses specific navigation economic evaluation and modeling issues that have been raised inside and outside the Corps and is responsive to our commitment to develop and use peer-reviewed tools, techniques a...

We extend results of [1, 2, 3] on the visibility problem for lattice points in Zd to the case of function fields over finite fields which are related to important questions regarding the corresponding q-Jacobsthal function. Résumé. Nous étendons résultats de [1, 2, 3] sur le probleme de la visibilité des points du réseau entier Zd au cas des corps de fonctions sur un corps fini, en rapport avec...

Soient p un nombre premier, et k un corps parfait de caractéristique p. On note W = W (k) l’anneau des vecteurs de Witt à coefficients dans k, K0 le corps des fractions deW et on fixe K une extension totalement ramifiée de K0 de degré e, d’anneau des entiers noté OK . On fixe également K̄ une cloture algébrique de K, on désigne par GK le groupe de Galois absolu de K et par I le sous-groupe d’ine...

Randomized and natural experiments are commonly used in economics and other social science fields to estimate the effect of programs and interventions. Even when employing experimental data, assessing the impact of the treatment on outcomes of interest is often complicated by the presence of sample selection (outcomes are only observed for a selected group) and noncompliance with the assigned t...
