A new species of Habralictus Moure (Apoidea, Halictidae) is described from the island of Dominica, Habralictus gonzalezisp. n. The species is distinguished from other West Indian Habralictus and a key is provided to the West Indian Habralictus. Brief comments on the genus Habralictus and bee species of Dominica are provided.

We measured the mechanical properties of the respiratory system of C57BL/6 mice using the optimal ventilation waveform method in closed- and open-chest conditions at different positive end-expiratory pressures. The tissue damping (G), tissue elastance (H), airway resistance (Raw), and hysteresivity were obtained by fitting the impedance data to three different models: a constant-phase model by ...

The primary concern of this paper is understanding how prices and interest rates respond to open-market operations. In a model economy developed by Grossman and Weiss, but with more general utility functions, we establish global existence of equilibrium paths and observe that prices and interest rates rise initially, but thereafter oscillate around a new steady state. Also investigated are opti...

In this essay I will explore an understanding of the potential moral agency of robots, arguing that the key characteristics of physical embodiment, adaptive learning, empathy in action, and a teleology toward the good are the primary necessary components for a machine to become a moral agent. In this context, other possible options will be rejected as necessary for moral agency, including simpl...

Question: Does the relative importance of stochastic and deterministic factors change during primary succession? Location: Small depressions (potholes) located onMount St. Helens, Washington (4611305100N, 12210901000W, 1290m). Methods: Pothole vegetation was described in 1993, 1997 and from 2001 to 2008. Explanatory variables included location and elevation (spatial factors), soil factors and L...

The HAL 9000 computer, the inimitable star of the classic Kubrick and Clarke film "2001: A Space Odyssey," displayed image understanding capabilities vastly beyond today’s computer systems. HAL could not only instantly recognize who he was interacting with, but also he could lip read, judge aesthetics of visual sketches, recognize emotions subtly expressed by scientists on board the ship, and r...

An ab initio study of the mono-and difluorides of krypton. Results from ab initio calculations at the CCSD͑T͒ level of theory are presented for krypton monofluoride ͑KrF͒, krypton monofluoride cation (KrF ϩ), linear, ground-state krypton difluoride (KrF 2), the triplet state of krypton difluoride, and the krypton–fluorine van der Waals complex (Kr–F 2). These are the first calculations demonstratin...
