A preliminary treatment of the genus Campylopus (Musci: Dicranaceae) in Central America

There are 26 species of Campylopus in Central America. They are divided into three groups on the basis of two characters: the presence or absence in the costa of a ventral layer of enlarged, hyaline cells and the presence or absence in the stem of an outer hylodermis. Dicranum costaricensis Bartr. is transferred to Campylopus as C. valerioi nom. nov. Campylopus hoffmanii and C. standleyi are recognized as distinct species. Six new synonyms are proposed: C. straminifolius = C. densicoma; C. costaricensis = C. surinamensis; C. roellii = C. tallulensis; C. donnellii = C. zygodonticarpus; C. tuerckheimii = C. zygodonticarpus; C. sargii = C. zygodonticarpus

A revision of the genus Crossomitrium (Musci: Hookeriaceae)

Crossomitrium is a genus of neotropical, essentially epiphyllous mosses. The genus consists of six species that are distributed in two sections: section Crossomitrium (C. acuminatum, C. patrisiae, and C. scabrisetum) and section Cormophila (C. epiphyllum, C. saprophilum, and C. sintenisii). Section Crossomitrium is characterized by 1. plants nearly always on leaves or twigs, 2. lateral leaves oblongacuminate and widest below the middle, 3. leaves when dry that arch from an erect base downward to the substrate and, 4. the presence of specialized brood branches that are closely adnate to the substrate and have tightly imbricate leaves. Section Cormophila is characterized by 1. plants growing on rocks and tree trunks as well as on leaves, 2. lateral leaves oval to obovate, acute to apiculate and widest above the middle, 3. leaves when dry flattened to the substrate and, 4. the presence of erect, specialized brood branches that have leaves spreading on all sides. Crossomitrium is placed in the Hookeriaceae (sensu Whittemore & Allen, 1989) on the basis of its branched stems, ecostate leaves, straight, unbranched rhizoids that are tightly clustered just posterior to the leaf bases, 2-celled axillary hairs and weakly pigmented stem cortex. Within the Hookeriaceae Crossomitrium is considered close to the genus Lepidopilum by virtue of 1. its peristome which is hydrocastique and has a high basal membrane, 2. the spinose setae of C.acuminatum and C. scabrisetum, 3. the irregular subdivision of its stomatal guard cells (including the presence of stomates at the base of raised pustules), 4. leaves doubly serrulate by the projecting ends of contiguous marginal cells, 6. absence of a stem central strand. It differs from Lepidopilum in its 1. symmetric, ecostate leaves, 2. calyptra fimbriate by downward projecting, multicellular hairs that arise from the margins of the calyptra, 3. collenchymatous exothecial cells, 4. the presence of broodbodies on specialized brood branches as well as in clusters just below the junction of the leaf with the stem

Stable ac phase and amplitude comparator

Stable ac phase and amplitude comparator detects excessive vehicle maneuvering or vibration. It has phase demodulation, low-pass filter, and multiple threshold-setting capability designed specifically for low drifts over a wide range of temperatures

Oviposition by \u3ci\u3eDendrosoter Protuberans\u3c/i\u3e (Hymenoptera: Braconidae) on Larvae of \u3ci\u3eScolytus Multistriatus\u3c/i\u3e (Coleoptera: Scolytidae) Occupied by Larvae of \u3ci\u3eEntedon Leucogramma\u3c/i\u3e (Hymenoptera: Eulophidae)

Dendrosoter protuberans (Nees) was introduced into the United States from France as a possible addition to the existing spectrum of hymenopterous parasites of the smaller European elm bark beetle, Scolytus multistriarus (Marsham). D. protuberans is an external parasite; it oviposits through bark onto or next to late-instar larvae of S. multistriatus (Kennedy 1970) (Fig. 1)

On the rotational symmetry of 3-dimensional κ\kappa-solutions

In a recent paper, Brendle showed the uniqueness of the Bryant soliton among 3-dimensional $\kappa$-solutions. In this paper, we present an alternative proof for this fact and show that compact $\kappa$-solutions are rotational symmetric. Our proof arose from independent work relating to our Strong Stability Theorem for singular Ricci flows.Comment: 20 page

Anomalous event diagnosis for environmental satellite systems

The National Oceanic and Atmospheric Administration's (NOAA) National Environmental Satellite, Data, and Information Service (NESDIS) is responsible for the operation of the NOAA geostationary and polar orbiting satellites. NESDIS provides a wide array of operational meteorological and oceanographic products and services and operates various computer and communication systems on a 24-hour, seven days per week schedule. The Anomaly Reporting System contains a database of anomalous events regarding the operations of the Geostationary Operational Environmental Satellite (GOES), communication, or computer systems that have degraded or caused the loss of GOES imagery. Data is currently entered manually via an automated query user interface. There are 21 possible symptoms (e.g., No Data), and 73 possible causes (e.g., Sectorizer - World Weather Building) of an anomalous event. The determination of an event's cause(s) is made by the on-duty computer operator, who enters the event in a paper based daily log, and by the analyst entering the data into the reporting system. The determination of the event's cause(s) impacts both the operational status of these systems, and the performance evaluation of the on-site computer and communication operations contractor
