A simple disc wind model for broad absorption line quasars
No full textApproximately 20 per cent of quasi-stellar objects (QSOs) exhibit broad, blue-shifted absorption lines in their ultraviolet spectra. Such features provide clear evidence for significant outflows from these systems, most likely in the form of accretion disc winds. These winds may represent the ‘quasar’ mode of feedback that is often invoked in galaxy formation/evolution models, and they are also key to unification scenarios for active galactic nuclei (AGN) and QSOs. To test these ideas, we construct a simple benchmark model of an equatorial, biconical accretion disc wind in a QSO and use a Monte Carlo ionization/radiative transfer code to calculate the ultraviolet spectra as a function of viewing angle. We find that for plausible outflow parameters, sightlines looking directly into the wind cone do produce broad, blue-shifted absorption features in the transitions typically seen in broad absorption line (BAL) QSOs. However, our benchmark model is intrinsically X-ray weak in order to prevent overionization of the outflow, and the wind does not yet produce collisionally excited line emission at the level observed in non-BAL QSOs. As a first step towards addressing these shortcomings, we discuss the sensitivity of our results to changes in the assumed X-ray luminosity and mass-loss rate, Ṁwind. In the context of our adopted geometry, Ṁwind ∼ Ṁacc is required in order to produce significant BAL features. The kinetic luminosity and momentum carried by such outflows would be sufficient to provide significant feedback

This new species is similar to Suberites waedoensis Shim and Sim 2008 in sponge shape and spicules composition, but differs in surface, texture and color. This new species has grayish red color, and texture firm with extremely rough surface.Published as part of Kim, Young A & Sim, Chung Ja, 2021, Ten new species of families Suberitidae and Polymastiidae (Demospongia: Heteroscleromorpha) from Korea, pp. 168-183 in Journal of Species Research 10 (2) on page 175, DOI: 10.12651/JSR.2021.10.2.168, http://zenodo.org/record/812001
BLGAN: Bayesian Learning and Genetic Algorithm for Supporting Negotiation With Incomplete Information
No full textAutomated negotiation provides a means for resolving
differences among interacting agents. For negotiation with
complete information, this paper provides mathematical proofs
to show that an agent’s optimal strategy can be computed using
its opponent’s reserve price (RP) and deadline. The impetus of
this work is using the synergy of Bayesian learning (BL) and
genetic algorithm (GA) to determine an agent’s optimal strategy
in negotiation (N) with incomplete information. BLGAN adopts:
1) BL and a deadline-estimation process for estimating an opponent’s
RP and deadline and 2) GA for generating a proposal
at each negotiation round. Learning the RP and deadline of an
opponent enables the GA in BLGAN to reduce the size of its search
space (SP) by adaptively focusing its search on a specific region
in the space of all possible proposals. SP is dynamically defined
as a region around an agent’s proposal P at each negotiation
round. P is generated using the agent’s optimal strategy determined
using its estimations of its opponent’s RP and deadline.
Hence, the GA in BLGAN is more likely to generate proposals
that are closer to the proposal generated by the optimal strategy.
Using GA to search around a proposal generated by its current
strategy, an agent in BLGAN compensates for possible errors in
estimating its opponent’s RP and deadline. Empirical results show
that agents adopting BLGAN reached agreements successfully,
and achieved: 1) higher utilities and better combined negotiation
outcomes (CNOs) than agents that only adopt GA to generate their
proposals, 2) higher utilities than agents that adopt BL to learn
only RP, and 3) higher utilities and better CNOs than agents that
do not learn their opponents’ RPs and deadlines

Rho, Kim and Sim, 1969: 156, pl. 2, fig. 7. Type specimen. Holotype (NIBRIV0000879327), Korea: Yeongilman, Guman-ri, Homigot-myeon, Pohang-si, Gyeongsangbuk-do, 25 July 1967, Rho BJ, by fishing net, deposited in NIBR. Description. Irregular elliptical mass sponge, size up to 9 × 4.5 × 3 cm. Upper surface with lobate projections and underside smooth with a large hole, 1.5 × 1 cm in diameter. Pagurus pectinatus, a crustacean (hermit crab), resides in the hole. Oscules rare, 0.7-1 mm in diameter. Color in life orange red. Texture firm and compressible. Skeleton: Small tylostyles and microrhabds arranged tangentially at the surface. Large tylostyles showed at subsurface (Fig. 3C). Mostly small and large tylostrongyles appeared at the underside of the sponge near the hole (Fig. 4B). Numerous microrhabds appear at inside wall of the sponge hole. Spicules. Tylostrongyles, 70- 110-350 × 5-15 μm and tylostyles, 110-340 × 8-10 μm. Microrhabds, 20-35 μm. Etymology. The species name, youngilensis, is named after the type locality of Youngilman, Gyeongsangbuk-do. Remarks. This new species is easily distinguished from Suberites ficus Johnston (1842) in shape and spicules. Suberites ficus has a pear shape, surface even, without hole containing hermit crab, and also spicules without microscleres. This new species is not sessile, but independent because no part is attached to the substrate. There is no trace of any kind of shell in and out of the sponge. Tanita (1965) observed that specimens occupied by hermit crabs are very rare, however, most of our specimens contained hermit crabs in the underside hole. Lobate projection of the upper part of sponge is variable, some few large lobes or many small lobes.Published as part of Kim, Young A & Sim, Chung Ja, 2021, Ten new species of families Suberitidae and Polymastiidae (Demospongia: Heteroscleromorpha) from Korea, pp. 168-183 in Journal of Species Research 10 (2) on page 169, DOI: 10.12651/JSR.2021.10.2.168, http://zenodo.org/record/812001

No full textEvolving Fuzzy Rules for Relaxed-Criteria Negotiation
No full textIn the literature on automated negotiation, very few negotiation agents are designed with the flexibility to slightly relax their negotiation criteria to reach a consensus more rapidly and with more certainty. Furthermore, these relaxed-criteria negotiation agents were not equipped with the ability to enhance their performance by learning and evolving their relaxed-criteria negotiation rules. The impetus of this work is designing market-driven negotiation agents (MDAs) that not only have the flexibility of relaxing bargaining criteria using fuzzy rules, but can also evolve their structures by learning new relaxed-criteria fuzzy rules to improve their negotiation outcomes as they participate in negotiations in more e-markets. To this end, an evolutionary algorithm for adapting and evolving relaxed-criteria fuzzy rules was developed. Implementing the idea in a testbed, two kinds of experiments for evaluating and comparing EvEMDAs (MDAs with relaxed-criteria rules that are evolved using the evolutionary algorithm) and EMDAs (MDAs with relaxed-criteria rules that are manually constructed) were carried out through stochastic simulations. Empirical results show that: 1) EvEMDAs generally outperformed EMDAs in different types of e-markets and 2) the negotiation outcomes of EvEMDAs generally improved as they negotiated in more e-markets
