This Mess is a Place: A Collapsible Anthology of Collections and Clutter
No full text'This Mess is a Place' examines hoarding and its relationship to collection across disciplines. Art practice and critical theory co-exist with clinical and scientific research, thus creating overlaps and crises of ‘usefulness’ akin to submersion of materials within a hoard or pursuits of order within collection. The publication is unbound – illogical and precarious, containing loose leaves and nominal filing systems. The reader is ultimately responsible for ordering/dis-ordering the piece.
25 x 19 cm, 205 pages, digital and risograph printing, varied papers, portfolio of pamphlets and loose leaves in a printed card folio.

Diagnosis. A member of P. unistrigatus (sensu Lynch and Duellman 1997, as modified by Duellman and Pramuk 1999, Hedges et al. 2008,) diagnosed by having (1) skin texture of dorsum shagreen with scattered tubercles, those on venter areolate; (2) tympanic membrane and annulus evident, 29.7–40 % of eye length on females and 25.2–32.3 % on males, with supratympanic ridge obscuring upper and posterodorsal edges; (3) snout rounded in profile and dorsal views; (4) upper eyelid bearing one large, and several small scattered, conical tubercles; cranial crests absent; (5) dentigerous process of the vomer triangular and narrowly separated, each bearing 4–6 teeth; (6) vocal slits and vocal sac absent in males, nuptial pads present (Fig. 5); (7) first finger shorter than the second, fingers with expanded discs; (8) fingers with lateral fringes; (9) ulnar tubercles small; (10) heel with one enlarged conical tubercle; tarsus with 3–4 tubercles along the outer edge; (11) two metatarsal tubercles prominent, inner oval, about three times the size of the outer subconical tubercle; numerous supernumerary plantar tubercles; (12) toes with lateral fringes; (13) in ethanol, dorsum tan, gray or dark gray, with darker markings (sometimes chevrons or bars) outlined by white or black lines; venter cream to pale cream with darker spots; palmar and plantar surfaces gray, with Fingers I–II, and Toes I–III being the palest; (14) adults medium sized, in males 19.06–24.33 SVL (= 22.17 + 2.01, n = 6), females 26.83–33.64 SVL (= 30.63 + 3.10, n = 5). We assign this species to the Pristimantis unistrigatus group based on the following characters: narrow head (head width 38.5–42.6 % of SVL in females and 38.3–41.9 % in males); absence of cranial crests; upper eyelid as wide as, or wider than, IOD (75.1–96.9 % in females, 96.0–112.0% in males); skin on venter aerolate; nuptial pads present; tympanic membrane evident; discs on fingers and toes broad; Finger I shorter than Finger II and toes being unwebbed. Comparisons. Pristimantis gagliardoi may easily be identified by the presence of large, conical tubercles on the eyelids and heels. This species differs from other species in the group that have some degree of development of such tubercles as follows and by the presence/absece of other characters (condition of P. gagliardoi in parentheses) (Table 1): Pristimantis cryptomelas (Lynch 1979) is the species most similar to P. gagliardoi, but differs by having a black coloration on the anterior and posterior sides of thighs, the posterior lower flanks, and the concealed portion of the shank (pale reddish), by having smooth skin (shagreen with scattered distinct tubercles), by lacking a conical tubercle over the eye (present), and by having larger pads on the digits of the hands and feet. Pristimantis inusitatus (Lynch & Duellman, 1980) differs by having a green dorsum and white venter (dorsum pale brown with variable dark brown markings, venter cream with variable dark brown reticulations or markings), conical tubercle on upper eyelid (present, but larger in P. gagliardoi), snout protruding in profile and subcauminate in dorsal view (rounded in both views). Pristimantis eriphus (Lynch & Duellman, 1980) has a straight canthus rostralis (weakly angular), adult females have red iris (bronze) and flanks with white areas and slightly oblique white bars on posterior flanks and hidden surfaces of hind limbs (bars on flanks). Pristimantis prolatus (Lynch & Duellman, 1980) has no ulnar tubercles (few conical), vocal slits and vocal sac present in males (absent), Iris is gray brown (bronze), snout in profile nearly truncate and accuimnate in dorsal view (rounded in both views). Pristimantis nephophilus (Duellman and Pramuk, 1999) has a few, small tubercles on the posterior eyelid (small tubercles scattered over surface of eyelid, and a single, large, central, conical tubercle), dark brown coloration with cream spots on the posterior thighs (pale reddish), brown coloration on the venter (cream with variable markings), all tubercles on the feet and hands weakly developed (strongly developed), smoother skin, lacking pronounced tubercles (shagreen with scattered distinct tubercles), and discs on the hind digits being slightly smaller than those of fingers (equal in size). Description of the holotype.

Etymology. The specific name is a noun in the genitive case and is a patronym for Ron Gagliardo, dedicated collaborator in both research and conservation programs involving Neotropical amphibians. Gagliardo has been important in promoting amphibian research, environmental education, but especially for supporting the establishment of captive breeding programs for the threatened Ecuadorian frogs. Distribution and ecology. Pristimantis gagliardoi is known only from La Libertad, Reserva Mazar (S 0 2 32 ' 47 '' S, 0 78 41 ' 54.1 '' W, 2895m), Provincia Cañar, Ecuador. This site, a small farm, is located on the western versant of the Ecuadorian Andes in Bosque de neblina montano (Montane cloud forest) and Bosque siempreverde montano alto (Evergreen montane forest) according to Valencia et al. (1999) (Fig. 6). The species has been found on leaves and branches at heights varying from 0.40–1.50 m above ground (= 0.775 m), mainly in secondary forests (12 of 16 individuals), and on vegetation over very small stream (2 of 16) and in primary forest (1 of 16). During our visits (six field trips since February 2004) to La Libertad, P. gagliardoi showed seasonal activity. During the wettest months we found it in primary and secondary forest as well as along small streams. In drier months (October and November) we found it along streams. An adult female (QCAZ 32623) obtained on 20 November, 2006, contained mature eggs in the oviducts. Pristimantis gagliardoi occurs sympatrically with Gastrotheca pseustes, Hyloxalus vertebralis, P. orestes, P. pycnodermis, P. riveti and an undescribed Pristimantis species.Published as part of Bustamante, Martín R. & Mendelson, Joseph R., 2008, A new frog species (Strabomantidae: Pristimantis) from the High Andes of Southeastern Ecuador, pp. 49-59 in Zootaxa 1820 on pages 50-57, DOI: 10.5281/zenodo.18299
The Equivalence of the Radial Return and Mendelson Methods for Integrating the Classical Plasticity Equations
No full textThe radial return and Mendelson methods for integrating the equations of classical plasticity, which appear independently in the literature, are shown to be identical. Both methods are presented in detail as are the specifics of their algorithmic implementation. Results illustrate the methods' equivalence across a range of conditions and address the question of when the methods require iteration in order for the plastic state to remain on the yield surface. FORTRAN code implementations of the radial return and Mendelson methods are provided in the appendix
Velocity Anisotropy Of Two Deep Crystalline Samples
No full textUsing ultrasonic velocity measurements taken over a multiplicity of directions we show
that samples exhibit weak to moderate anisotropy of seismic velocities. We further
define the anisotropic geometry with high resolution scanning electron microscopy.
Our data indicate that one sample, a granite, is transversely anisotropic, and that the
presence of fine to moderately fine microcracks is the most important factor effecting
the velocities. We model the angular velocity dependence using 5 elastic constants
and show that all 9 observed velocities fit these predictions to within 0.1 km/s. We
are unable to obtain similar fits to a second sample, a mica-schist, in the same fashion.
SEM observations indicate this rock displays orthorhombic symmetry. We made
additional velocity measurements in order to calculate 9 elastic constants, and found
that the predicted angular velocity dependence agreed much better with our velocity
observations.Massachusetts Institute of Technology. Full Waveform Acoustic Logging ConsortiumEnte nazionale per l'energia elettric

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Suprema of Chaos Processes and the Restricted Isometry Property
No full textWe present a new bound for suprema of a special type of chaos process indexed by a set of matrices, which is based on a chaining method. As applications we show significantly improved estimates for the restricted isometry constants of partial random circulant matrices and time-frequency structured random matrices. In both cases the required condition on the number m of rows in terms of the sparsity s and the vector length n is m s log(2)s log(2)n. (c) 2014 Wiley Periodicals, Inc
