Adult Description. Body oval; males (Fig. 3) smaller than females (Figs. 1–2, 4); males 4.6–5.0 mm long and 2.75 mm wide, females 5.0– 5.6 mm long and 2.8–3.5 mm wide. Integument color medium brown, shiny where setae sparse; covered dorsally with a combination of different kinds of setae: widely-spaced, long, erect blond and dark brown setae; sparse, shorter, pale brown setae; and very dense, recumbent, pale blond setae forming a pattern of broad bands and large spots. Venter uniformly clothed in medium-length pale blond setae. Aedeagus of trilobed type (Fig. 25) and lightly sclerotized. Basal piece long, reduced to ventral plate basally with lateral flanges that clasp the base of parameres. Parameres long, widest at apical three-fourths of aedeagus; tips narrow, curved laterally; dorsally conjoined just anterior to midlength. Penis lanceolate; shorter than parameres; tip slightly curved ventrally and laterally compressed; base deeply cleft. 1. Ectopria is omitted from the key because it is probable that the Neotropical species belong in other genera.

Habitat. The type locality in Parque Nacional Rincón de la Vieja at an 780 m is a series of seeps in a small basin connected by a spring run to a narrow, slow-flowing forest stream which is a tributary of the Río Colorado. The entire area around the seeps and both streams is heavily forested and generally heavily shaded. In the seep basin the water is only about 2–3 cm deep over a substrate composed of a thick deposit of silt and fine detritus on which lie sticks and larger pieces of rotting, waterlogged wood (Fig. 27). In the basin the water is extremely slowmoving but in a couple of meters it begins to flow downhill in a narrow spring run which is crossed by the Las Pailas Trail between Stops 3 and 4. Larvae and pupae of N. inbionis were collected on pieces of decomposing wood found in the seep basin. Larvae were positioned below the water’s surface and pupae were above. The water is likely hypoxic because of the fine organic detritus substrate, coupled with the lack of sunlight for aquatic photosynthesizers due to the heavily-shaded nature of the site. Possession of a plastron facilitates larval survival in this water. Neoeubria was the only psephenid present in the seep area, and the only other co-occurring aquatic byrrhoid Coleoptera was an unidentified ptilodactylid larva. Other arthropods present in the seep area included aquatic Hemiptera, Belostoma (Belostomatidae) and Ambrysus (Naucoridae), and the crustacean Hyallela (Amphipoda). No specimens were collected from the spring run formed by the seeps. A single larva was collected in a second, larger stream, Quebrada Pailas, a tributary of the Río Colorado, which is also located along the Las Pailas Trail. The other sites at which larvae were collected by the senior author are also forest streams, although with rocky substrates and faster flow. Although the particular microhabitat of the larvae at these sites is unknown, at all of them submerged wood was common. Neoeubria inbionis has been collected at elevations ranging from as low as 40+ m in Nicaragua, to as high as 780 m in Costa Rica. The Ecuadorian adults were all taken in Malaise traps which were set in a forested area to catch flies. Although we could obtain no further information beyond the label data, collection of adults via Malaise traps indicates that N. inbionis adults behave like other eubriine adults and fly near the aquatic habitat in which the larvae occur. Phylogeny. In the recent phylogeny of the Psephenidae by Lee et al. (2007), Neoeubria is included as “Genus A.” In the most parsimonious tree Neoeubria is placed in a basal trichotomy within the subfamily Eubriinae. The trichotomy positions Neoeubria in one branch, Sclerocyphon + Tychepsephus in another branch, and the remainder of the eubriine genera in a third branch.Published as part of Shepard, William D. & Barr, Cheryl B., 2014, Neoeubria inbionis Shepard & Barr, a new genus and new species of Neotropical water penny beetle (Coleoptera: Psephenidae: Eubriinae), with a key to the adult Eubriinae of the Neotropic Zone, pp. 553-568 in Zootaxa 3811 (4) on pages 564-567, DOI: 10.11646/zootaxa.3811.4.7, http://zenodo.org/record/491902

Excavation at Aguas Buenas, Robinson Crusoe Island, Chile, of a gunpowder magazine and the supposed campsite of Alexander Selkirk, together with an account of early navigational dividers
No full textExcavations were undertaken of a ruined building at Aguas Buenas, identified as an 18th-century Spanish gunpowder magazine. Evidence was also found for the campsite of an early European occupant of the island. A case is made that this was Alexander Selkirk, a castaway here from 1704 to 1709. Selkirk was the model for Defoe’s Robinson Crusoe. A detailed discussion is given of a fragment of copper alloy identifi ed as being from a pair of navigational dividers
Queerly Remembered: Tactical and Strategic Rhetorics for Representing the GLBTQ past
No full textThis dissertation explores a turn toward strategic public memories in the gay, lesbian, bisexual, transgender, and queer (GLBTQ) community. While GLBTQ people have long used memories to influence and persuade heterosexual audiences, these memories have largely been what Michel de Certeau labels tactical - fleeting, ephemeral texts built upon the detritus of dominant culture. In contrast, GLBTQ people increasingly deploy strategic memories that endure heterosexual forgetting, persist through time, and exert greater control in spaces of power. In four case studies, I examine the possibilities and pitfalls of the strategic turn for securing greater GLBTQ rights. The first case study examines the Alexander Wood statue and how gays and lesbians have used material rhetorics like commemorative sites to make their memories durable and to resist heteronormative forgetting. While highlighting Wood's "official" meaning, I also demonstrate how both traditionalist and camp viewers of the statue contest that meaning through performative viewing practices. The second case study, on counterpublic memories of bias crime victim Matthew Shepard, illustrates how counterpublic memories can oscillate between public spheres. In doing so, vernacular memories of Shepard seek to replace dominant memories that obscure systemic antigay violence, endow Shepard with "saintly" qualities, and limit diverse imagining of GLBTQ identity. The third case study, featuring efforts to include GLBT people into California public school curriculums, examines how advocates use a "rhetoric of contribution" to align GLBT people with the strategic rhetoric of American nationalism. This case also highlights the difficult choices marginalized groups must often make to enter strategic spaces, including "strategic forgettings" that render much of the GLBT past incomplete. The final case study details gay and lesbian rhetorical acts to ensure they are remembered as queer in the future. Examining two prominent death displays - Leonard Matlovich's Gay Vietnam Veterans Memorial and Patricia Cronin's Memorial to a Marriage - this chapter argues that both marked and unmarked strategies are required to disrupt the reterritorialization of gay and lesbian identity after death. This dissertation concludes by looking at George Segal's Gay Liberation statue, reviewing the value of the strategic turn, and pondering the future of queer public memory

Radiosurgery Treatment Planning via Nonlinear Programming
No full textThe Gamma Knife is a highly specialized treatment unit that pro-
vides an advanced stereotactic approach to the treatment of tumors,
vascular malformations, and pain disorders within the head. Inside a
shielded treatment unit, multiple beams of radiation are focussed into
an approximately spherical volume, generating a high dose shot of ra-
diation. The treatment planning process determines where to center
the shots, how long to expose them for, and what size focussing hel-
mets should be used, in order to cover the target with su cient dosage
without overdosing normal tissue or surrounding sensitive structures.
We outline a new approach that models the dose distribution nonlin-
early, and uses a smoothing approach to treat discrete problem choices.
The resulting nonlinear program is not convex and several heuristic ap-
proaches are used to improve solution time and quality. The overall
approach is fast and reliable; we give several results obtained from use
in a clinical setting
