New methods for bounding the number of points on curves over finite fields

, 2012
We provide new upper bounds on N_q(g), the maximum number of rational points on a smooth absolutely irreducible genus-g curve over F_q, for many values of q and g. Among other results, we find that N_4(7) = 21 and N_8(5) = 29, and we show that a genus-12

Effect of different management techniques on bird taxonomic groups on rice fields in the Republic of Korea

Scientific Reports, 2021
Many bird species rely on the ecological functions of rice field habitats (e.g., paddy, levee, road, and ditch). However, recent intensive practices are causing rice fields to provide fewer suitable habitats.

Anomalous Gluon Production and Condensation in Glasma

, 2013
The collinear color electric and magnetic fields have been discussed to be produced immediately after high energy heavy ion collisions. We discuss anomalous gluon production under the background gauge fields. The gluons are Nielsen-Olesen unstable modes.

AGROECOLOGY: POLYSEMY, PLURALISM AND CONTROVERSIES [PDF]

Ambiente & Sociedade, 2016
In recent years, a growing number of actors and institutions, in different countries, have begun using the notion of Agroecology, which has led to an expansion of its polysemy and its controversies. Taking this into account, this paper analyzes, based on

Pastoralist herd size maintenance during drought with the use of reseeded fields near Lake Baringo, Kenya

Pastoralism, 2022
Land degradation, loss of access to land resources, climate variability, socio-economic changes, and population increase are among the factors that contribute to forage shortage among the pastoral communities.
