Rationalizability of one-to-one matchings with externalities
No full textIn this paper, we show that the one-to-one matching model of Mumcu and Saglam (2008) studying stability under interdependent preferences is refutable. We also give a sufficient characterization of the set of matchings that are rationalizable inside the core.One-to-one matching Stability Externalities Rationalizability

Entanglement transfer via chiral and continuous-time quantum walks on a triangular chain
No full textWe investigate the chiral quantum walk (CQW) as a mechanism for an entanglement transfer on a triangular chain structure. We specifically consider two-site spatially entangled cases in short-time and long-time regimes. Using the concurrence as an entanglement measure; fidelity, and the Bures distance as the measure of the quality of the state transfer, we evaluate the success of the entanglement transfer. We compare the entangled state transfer time and quality in CQW against a continuous-time quantum random walk. We also observe the effect of mixed states on the entanglement transfer quality

(York, PA) (Figs. 2E – 7E) (Holotype: ANSP GI 19496) (LSID: urn:lsid:zoobank.org:act: F55674 B 6-1767-4 F64-ABEF-0347122944E0) —Dorsal body light to yellowish-grey, sometimes with a greenish tint. Black dots on dorsal surface. Ventral coloration and annuli numbers same as H. serendipitious n. sp. One pair of eyes close to each other on segment III (Fig. 7E). Male and female gonopores in position similar to H. serendipitious n. sp. Six pairs of testisacs intersegmentally arranged from XII/XIII to XVII/ XVIII; shape similar to H. stagnalis but smaller. Ejaculatory bulbs (atrial cornua) moderately longer, ovoidcylindrical, lying at a much lower level by the sides of the atrium, connected by slender ejaculatory ducts with sharp turn backwards into atrium in XIth segment. Ovisacs large, connected with long and curled common oviduct. Oviduct length almost equal to ovisacs (Figs. 2E, 4E). Six pairs crop caeca, 6th directed backwards and short, extending up to fourth intestinal caecum. Four pairs intestinal caecum, first two pairs slightly curved upward, third pair flat and last pair curved downward. Rectum short, “S” shaped, similar H. stagnalis (Figs. 3E, 5E). The dorsal nuchal scute of H. stagnalis from Europe has been depicted in a SEM-micrograph by Sawyer (1986, p. 538). Additional SEM identified differences in scute morphology and position between species (Fig. 8). Specifically, the s cute of Helobdella spp. ranged from rhomboidal to hexagonal, settled on the12th and extending to the 13th annulus The H. modesta scute was square-shaped, settled on the 12th annulus (on the VII-a1) and sometimes extending up to half the 13th annulus (Fig. 6B). The H. serendipitious scute was pentagonal, settled in the dorsal surface of segment VII-a2 (on annulus 12) (Fig. 6C). The Helobdella eriensis n. sp. (Farm Pond) scute was similar to H. serendipitious n. sp. but settled in the 12th and up to all of 13th annulus (Fig. 6D). The Helobdella echoensis n. sp. (York, PA) was similar to H. serendipitious n. sp. but mushroom shaped (Fig. 5E).Published as part of Saglam, Naim, Kutschera, Ulrich, Saunders, Ralph, Saidel, William M., Balombini, Katherine L.
