The logic of actual obligation The logic of An alternative approach to deontic logic. In this paper we develop a system of deontic logic (LAO, the"; logic of actual obligation) with a.rathep limited scope: we are, only interested in obligations as far as they: are; relevant for deciding: what: actions-actually ought to be done in a particular situation, given some normative system, N. In fact w...

Hydrophylita emporos n. sp. reared from eggs of Psolodesmus mandarinus mandarinus McLachlan (Zygoptera: Calopterygidae) in Taiwan is described. This is the first species of Hydrophylita to be described from the Old World, and the first record of phoresy in the genus. Adult females were observed aggregating at the base of the female damselfly's abdomen. When the damselfly begins ovipositing, fem...

The LAO-GDC solid composite electrolyte has been proposed for use in Solid Oxide Fuel Cells (SOFC). material conductivity of Carbonate-Ceria (SCC) electrolytes is 0.04Scm-1 between 400 and 700°C. For this purpose, mixtures LaAlO3 (LAO) gadolinium doped ceria Ce0.8Gd0.2O2 (GDC) were created weight ratios 3:1, 2:2, 1:3. was studied separately to improve conductivity. phase structure microstructur...

Trichinellosis is documented in Southeast Asia, particularly in Thailand and China. Data from Lao PDR are lacking. An outbreak investigation was conducted in Borikhamxay Province after three patients with suspected trichinellosis consulted the Mahosot Hospital, Vientiane. In total, 22 trichinellosis cases were identified; 21 cases could be confirmed by Western blot. High fever (100%), muscle pa...

The recently developed AFM local anodic oxidation (LAO) technique offers a convenient way of patterning nanodevices, but imposes even more stringent requirements on the underlying quantum well structure. We developed a new very shallow quantum well design which allows the depth and density of the 2D gas to be independently controlled during the growth. A high mobility (0.5×106 cm2 V−1 s−1 at 4....

LAO* is a heuristic search algorithm for Markov decision problems that is derived from the classic heuristic search algorithm AO* (Hansen & Zilberstein 1998). It shares the advantage heuristic search has over dynamic programming for simpler classes of problems: it can nd optimal solutions without evaluating all problem states. In this paper , we show that the derivation of LAO* from AO* makes i...
