Carex modesti (Cyperaceae), a new species from southern Tanzania

A new species of Carex (Cyperaceae), Carex modesti, is described from southern Tanzania. It grows on stream sides and peat bogs at about 2750 m in the Kitulo Plateau. It is morphologically distinct from the similar species C. vallis-rosetto by its creeping rhizomes, coriaceous leaves and solitary spikes arising in each node. Carex modesti is included in Carex sect. Spirostachyae subsect. Elatae together with other Carex species from the tropical African mountain

The group inverse of subdivision networks

In this paper, given a network and a subdivision of it, we show how the Group Inverse of the subdivision network can be related to the Group Inverse of initial given network. Our approach establishes a relationship between solutions of related Poisson problems on both networks and takes advantatge on the definition of the Group Inverse matrix.Peer ReviewedPostprint (author's final draft

Effective resistances and Kirchhoff index in subdivision networks

We define a subdivision network ¿S of a given network ¿; by inserting a new vertex in every edge, so that each edge is replaced by two new edges with conductances that fulfill electrical conditions on the new network. In this work, we firstly obtain an expression for the Green kernel of the subdivision network in terms of the Green kernel of the base network. Moreover, we also obtain the effective resistance and the Kirchhoff index of the subdivision network in terms of the corresponding parameters on the base network. Finally, as an example, we carry out the computations in the case of a wheel.Peer ReviewedPostprint (author's final draft

Next generation sequencing reveals the complete plastome sequence of newly discovered cliff-dwelling Sonchus boulosii (Asteraceae: Cichorieae) in Morocco

The complete chloroplast genome sequences of newly discovered cliff-dwelling species of Sonchus, S. boulosii, were reported in this study. The S. boulosii plastome was 152,016 bp long, with the large single copy (LSC) region of 83,988 bp, the small single copy (SSC) region of 18,566 bp, and two inverted repeat (IR) regions of 24,731 bp. The plastome contained 130 genes, including 88 protein-coding, six ribosomal RNA, and 36 transfer RNA genes. The overall GC content was 31.2%. Phylogenetic analysis of 12 representative plastomes within the order Cichorieae suggests that S. boulosii is closely related to S. oleraceus.National Research Foundation of Korea [NRF-2016R1D1A2B03934596

Estados Unidos en guerra contra las drogas: la mirada de la narcoliteratura

El gobierno estadounidense ha declarado una guerra contra las drogas que lleva aproximadamente medio siglo y obedece a un asunto de seguridad nacional, más que de salud pública. En este tiempo, han sido extraditados y apresados importantes narcotraficantes latinoamericanos, sin embargo, muy pocos ciudadanos estadounidenses se han visto involucrados públicamente en la industria, lo que establece una dicotomía entre criminales latinos y víctimas norteamericanas. La narcoliteratura entrega su propia visión histórica de esta guerra, cuestionando el hecho de que los estadounidenses no sean parte del negocio. Contrario al discurso oficial, los escritores Don Winslow, Armando Ayala Anguiano y Francisco Haghenbeck proponen que Estados Unidos ha utilizado la guerra contra las drogas a favor de sus propios intereses: con el fin de proteger las ganancias de sus altos empresarios, para apropiarse del negocio más lucrativo del mundo y para encubrir sus luchas políticas en contra del comunismo. Así, los escritores de la narcoliteratura estarían denunciando que Estados Unidos es parte fundamental de la red de narcotráfico internacional que busca combatir
