The genus Chrysellampus Semenov, 1932 is revalidated. Chinese species are revised and keyed for the first time. Five species are recorded, two of them are new for science: Chrysellampus obtusidentibus Rosa, Wei & Xu, sp. nov. (Yunnan), and C. proximocellis Rosa, Wei & Xu, sp. nov. (Gansu and Yunnan). New synonymy for Chrysellampus Semenov, 1932 (=Parellampus Semenov, 1932, syn. nov.) and new co...

The goal of the ROSA project is to develop a variableautonomy architecture to support ground-based control of space-deployed robotic systems in dynamic workspace environments. This capability is aimed at unmanned satellite servicing systems that must rendezvous with, capture and service free flying objects. As data communication limitations force the system to perform free flyer capture autonom...

Endophytes are fungi that cause asymptomatic infections in leaves and stems of healthy plants. This study evaluated the presence of endophytic fungi on leaves of Rosa hybrida collected in Bogota, (Colombia) using histological techniques and light microscopy. Histological preparations showed fungal mycelium with few cells in the vascular tissue. Colonization of mesophyll cells was not observed. ...

Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

Fractional calculus is the field of mathematical analysis which deals with the investigation and applications of integrals and derivatives of arbitrary order. The purpose of this work is to use Hadamard fractional integral to establish some new integral inequalities of Gruss type by using one or two parameters which ensues four main results . Furthermore, other integral inequalities of reverse ...

Responses of plant traits to climate changes are complex, which could be mirrored by the investigations of herbarium specimens. By examining specimens of Rosa and Cotoneaster species collected since 1920s in Hengduan Mountains, we analyzed the changes of flowering phenology and flower size in the past century when climate changes were considered to be intensified. We found that flowering phenol...

Rust fungi in the genus Phragmidium are frequent pathogens of both wild and cultivated roses. We investigated the occurrence and relationships of rusts on dog roses, Rosa sect. Caninae (Rosa canina, R. corymbifera and R. rubiginosa) in Germany. Two Phragmidium species, P. mucronatum and P. tuberculatum, were able to infect each of the three dog rose species examined. However, the overall infect...
