A record of gynandromorphism in the libellulid dragonfly Crocothemis servilia (Insecta: Odonata) from India

Here we report a case of gynandromorphism in the dragonfly Crocothemis servilia (Drury, 1773), (Insecta: Odonata: Anisoptera: Libellulidae) from the Puzhakkal region of Kole wetlands, Thrissur, Kerala, southern India from a single photograph recorded during a survey conducted on 14 July 2019. The individual exhibits bilateral gynandromorphism only in the thoracic region, half of which showed blood red colouration as in males and the other half pale yellow characteristic of females. The base of the wing of the red half was marked with rich amber, in contrast with the other wing base which was paler. The head, legs, and abdomen showed typical female morphology.

Single Image Super Resolution by Directionally Structured Coupled Lexicon Learning

In this paper, a alternative algorithmic software is deliberate supported coupled wordbook gaining knowledge of with mapping perform for the problem of single-photograph extremely good solution. Dictionaries rectangular degree designed-group of the carry out for clustered facts. The coaching information is based into 9 clusters supported correlation between the info patches and already evolved directional templates. The unchanging ness of the distributed representations is thought for the mission of wonderfulresolution. For each cluster, a integrate of high-decision and low-decision dictionaries rectangular measure designed in conjunction with their mapping-capabilities. This is a coupled word e book learning with a mapping performs enables in strengthening, the unchangingness of disbursed example coefficients for diverse resolution stages. throughout the reconstruction section, for a given low-decision patch a collection of directional clustered dictionaries square measure used, and also the cluster is chosen which elements the smallest amount allotted instance errors. The planned algorithmic application is as compared with in advance paintings in addition to the presently pinnacle-ranked incredible-decision algorithmic program. by the deliberate mechanism, the healing of directional fine options becomes extremely good.

For the Future Viewer: Salvage Ethnography and Edward Curtis's “The Oath – Apsaroke”

Since its reclamation in the 1970s, Edward S. Curtis's project to exhaustively photograph and describe American Indian cultures in the early twentieth century has invited shifting critical assessments. Complicating earlier arguments that it represents a nostalgic and inauthentic drama of a “vanishing” race, in which Indians functioned merely as props, recent scholars seek to recover his sitters’ agency or contemporary artists’ acts of reclamation. This article contributes to those efforts, but by exploring the temporal ambiguities inherent in the notion – then common among ethnographic photographers – of “preserving” a people for future viewers. It thus examines a photograph that Curtis contributed in 1913 to the Modern Historic Records Association, a short-lived organization that intended to assemble time capsules and archival vaults for historians in the distant future. Focussing on this single photograph – “The Oath – Apsaroke” (1908) – also allows us to track the way that Curtis's images could break free from his book project and resonate unpredictably across multiple domains, such as debates over the existence and meaning of Indian oaths.
