No full textGansuceratoikiscum Wang, Cheng & Zhang, 2010 Gansuceratoikiscum Wang, Cheng & Zhang, 2010: 48. TYPE SPECIES. — Gansuceratoikiscum guanzhuangensis Wang, Cheng & Zhang, 2010 (Wang et al. 2010: 473, pl. 1, fig. 11). AGE AND LOCATION OF TYPE MATERIAL. — Sandbian, Upper Ordovician, Pingliang Formation, Gansu Province, China. TAXON CODE. — 015. STATUS. — Valid. DIAGNOSIS. — “Six rod-like primary spines positioned in eccentric place. The pairs of caveal ribs are paired on the dorsal rod of the a-rod; The patagial tissue is present on one lateral side of the i-rod. A single row of arches (or by-spines) connect the primary spines, forming a simple cortical shell.”(Wang et al. 2010: 48). REMARKS This genus differs from Protoceratoikiscum in that it has a framework composed of 6 rods connecting to a median bar. Ceratoikisum has 3 rods (a, b, intersector) that cross to form a triangle. It differs from Protoceratoikiscum in that it possesses row of arches that connect the primary rods to form a subcircular shell, and the rods join in an eccentric position in Gansuceratoikiscum.Published as part of Noble, Paula, Aitchison, Jonathan C., Danelian, Taniel, Dumitrica, Paulian, Maletz, Jörg, Suzuki, Noritoshi, Cuvelier, Jessie, Caridroit, Martial & O'Dogherty, Luis, 2017, Taxonomy of Paleozoic radiolarian genera, pp. 419-502 in Geodiversitas 39 (3) on page 424, DOI: 10.5252/g2017n3a4, http://zenodo.org/record/520658
Light People: Professor Cheng Zhang
No full textEditorial Nanophotonics has emerged as a cutting-edge interdisciplinary research field today. Its primary objective is to leverage the interaction between light and matter at the wavelength and sub-wavelength scales, with the purpose of designing and manufacturing miniaturized, multifunctional, and high-performance optical devices and systems. Professor Cheng Zhang from Huazhong University of Science and Technology has dedicated his career to nanophotonic device research. His work encompasses a wide range of areas, including plasmonic devices, optical metamaterials, and metasurfaces. Through the design of innovative artificial electromagnetic structures and the exploration of emerging nanofabrication techniques, Professor Cheng Zhang has effectively achieved versatile control over various properties of electromagnetic waves, including amplitude, phase, and polarization states. Furthermore, his research extends to the continuous exploration of novel optical phenomena, aimed at realizing high-performance engineering applications. In this edition of Light People, we will take you deep into the world of Professor Cheng Zhang, a young scientist exemplifying the spirit of innovation, relentless improvement, and unwavering pursuit of excellence. You will discover how he has overcome numerous challenges in the realm of nanophotonic research

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
