Symmetry conservation in fukui functions
No full textThe problem of symmetry breaking in the evaluation of Fukui functions is addressed. It is also demonstrated that a reliable solution of the problem can be achieved using analytic methods. An automatic method that avoids occurrence of symmetry breaks has been implemented in a computer code and is described here. Negative regions of the Fukui function are shown to play a key role for the interpretation of reactivity. Example plots are presented for diatomic molecules, inorganic molecules, conjugated systems, and molecular cages. The potentiality of the Fukui functions as molecular scalar fields for prediction and analysis of regioselectivity is enhanced. Its advantages with respect to the use of condensed Fukui functions are discussed. Copyright � 2010 American Chemical Society

Invariants for bi-Lipschitz equivalence of ideals
No full text[EN] We introduce the notion of bi-Lipschitz equivalence of ideals and derive numerical invariants for such equivalence. In particular, we show that the log canonical threshold of ideals is a bi-Lipschitz invariant. We apply our method to several deformations ft:,0,0 (. n). (.) and show that they are not bi-Lipschitz trivial, specially focusing on several known examples of non-m*-constant deformations.The first author was partially supported by DGICYT Grant MTM2015-64013-P.Bivià-Ausina, C.; Fukui, T.

An investigation of the reactivity of [(diimine)(dithiolato)M] complexes using the Fukui functions concept
No full textFukui functions are widely used when investigating the reactivity of organic molecules, but rarely with metal complexes. Here, we investigate the reactivity of [(diimine)(dithiolato)M] complexes with different types of reagents and upon oxidation employing this concept. Mixed-ligand complexes of this type have a peculiar electronic description due to the mixed-metal-ligand- to-ligand charge-transfer band, which is why they are considered as very promising candidates for non-linear optical (NLO) materials and molecular photochemical devices (MPD). As a result, their reactivity is of crucial importance for their potential applications. The obtained results of f + and f- for the neutral [(diimine)(dithiolato)M] complexes (M = Pd, Ni and Pt) not only predict that the sulfur atom is the preferable active site for electrophilic attack but also reveal the different tunability of these complexes when they are subjected to an oxidation process, in agreement with experimental results. Under the framework of the Fukui indices we also provide an alternative explanation for crystal packing that could find widespread application. © Wiley-VCH Verlag GmbH &amp; Co. KGaA, 2006

Distribution. Currently known only from the Philippines (Fig. 3). Etymology. The new species is named zonalis (from Latin zona, meaning stripes), in reference to the vertical stripes on the body. Remarks. Terelabrus zonalis sp. nov. is uniquely characterized by higher counts of scale rows in longitudinal series 44 (vs. 41 or 42 in T. dewapyle) and pored lateral-line scales 42 (vs. 39 or 40 in T. dewapyle); lower counts of gill rakers 11–12 (vs. 14 or 15 in T. rubrovittatus) (Table. 1); 8 posterior branches off the main supratemporal sensory canal (vs. 4–6 in T. dewapyle, 4–5 in T. rubrovittatus); 3 scale rows in the area bounded by the main supratemporal and postotic sensory canals (dorsal view) (vs. embedded in T. flavocephalus); shorter least distance between the orbit anteroventral margin and maxilla [1.5–1.8% (mean 1.7%) of SL vs. 1.2–3.7% (mean 2.5%) in T. dewapyle]; greater least distance between the ventral margins of the orbit and interopercle [7.0 % of SL vs. 2.6– 5.5% (mean 3.5%) in T. dewapyle, 4.5% in T. flavocephalus, 3.4–4.4% (mean 3.7%) in T. rubrovittatus]; 9 procurrent rays in both dorsal and ventral series in caudal fin (vs. 7–8 in T. dewapyle, 7 in T. flavocephalus, 8 in T. rubrovittatus); larger predorsal bone, its width ca. five times that of other species of Terelabrus. The preserved coloration of T. zonalis also differs from that of T. dewapyle, T. flavocephalus and T. rubrovittatus, in that it is the first record of silver vertical bands (18 faint) on the body in any of the recognized species. New record of Terelabrus dewapyle. An individual Terelabrus specimen, photographed at 75 m depth off Nalusuan Island, the Philippines, was identified as T. dewapyle in having a yellow stripe between the upper and midlateral red body stripes, no red blotches superimposed on the midlateral red stripe, no yellow band on the dorsal fin and no vivid yellow stripes on the cheek. Terelabrus dewapyle has been previously recorded only from Japan, Papua New Guinea and Fiji on the basis of voucher specimens (Randall & Fourmanoir 1998; Fukui & Motomura 2015), and from Indonesia and Japan from underwater photographs (Kuiter & Debelius 2006; Motomura et al. 2010; Kuiter 2012; Allen & Erdmann 2012; Nishiyama & Motomura 2012). Therefore, the specimen photographed at Nalusuan Island represents the first evidence of T. dewapyle from the Philippines. H indicates holotype. * Scale counts could not be made on one T. dewapyle specimen due to body damage.Published as part of Fukui, Yoshino, 2018, A new species of Terelabrus (Perciformes: Labridae) from the Philippines with a key to species of Terelabrus and new record of Terelabrus dewapyle in Zootaxa 4526 (1), DOI: 10.11646/zootaxa.4526.1.6, http://zenodo.org/record/261144

Scales cycloid and thin; lateral-line scales continuous, following dorsal contour of body, posterior scales descending toward lateral mid-line; last 2 pored scales on base of caudal fin larger than anterior pored scales; each pored scale anteriorly on lateral line having tubule angling upward with single pore at end, each pored scale on lateral line near base of caudal fin with single horizontal tubule. Scales on side of thorax becoming smaller anteriorly on isthmus. Scales in front of dorsal fin extending forward to vertical through preopercular margin, predorsal scales variable in size. Scales covering opercle, except for membrane. Size of largest scale behind orbit about one-third of those on opercle; scales behind orbit extending forward to anterior margin of orbit. No scales on fins, except base of caudal fin. Preopercular margin smooth. Opercular membrane extending above upper base of pectoral fin. All dorsal-, anal-, and pelvic-fin soft rays branched; all pectoral-fin rays, except upper two, branched (all rays unbranched in 36.8 mm specimen). Dorsal- and anal-fin spines slender; space between each base of spines and rays subequal. Pectoral fins weakly rounded, eighth ray longest; pelvic fins short, third soft ray longest; caudal fin rounded. Origin of dorsal fin slightly posterior to vertical through origin of pectoral fin; posterior tip of pectoral fin anterior to vertical through base of sixth dorsal-fin spine; origin of pelvic fin slightly posterior to vertical through origin of pectoral fin; anus below base of ninth dorsal-fin spine; origin of anal fin below base of first dorsal-fin soft ray. Color of individuals when alive. Based on published underwater photographs (see synonymy above), Figs 1 D– F, and 10 unpublished photographs taken by H. Nishiyama in Japan (specimens not retained): body white with two longitudinal red stripes; midlateral stripe extending from snout to caudal-fin margin, its width less than orbit diameter anteriorly and posteriorly, and more than orbit diameter near middle; upper stripe extending from behind snout dorsally to upper end of caudal-fin base, its width less than one-fourth that of midlateral stripe; pair of upper stripes confluent dorsally on snout in dorsal view. No red blotches superimposed on midlateral red stripe in adults or young; more than 20 red, poorly defined, faint, narrow vertical bars extending below midlateral red stripe in large adults. Space between upper and midlateral red stripes vivid yellow in adults and young, forming yellow stripe extending from upper margin of eye to middle of caudal fin. Yellowish white stripe from dorsal side of snout to anterodorsal margin of orbit. Black blotch, about subequal to pupil diameter, superimposed on midlateral red stripe on opercle in young, blotch fading, becoming almost indistinguishable, with growth. Dorsal and pectoral fins transparent. Anal fin whitish or yellowish basally, transparent distally. Caudal fin transparent apart from posterior ends of midlateral red stripe and upper yellow stripe; with poorly defined blackish blotch posteromedially. Color of holotype when fresh. Based on Fig. 1 A and an unpublished photograph with white background: mostly similar to live individuals described above, but midlateral red stripe becoming wider and yellow stripe between upper and midlateral stripes narrower and yellow coloration somewhat faded. Caudal fin with pare of small white blotches and narrow white margin. No other photographs of fresh specimens known. Color of preserved specimens. Based on holotype (Fig. 1 B) and all paratypes: body pale yellow with distinct brown blotch on opercle. Very faint brownish stripes from behind orbit to blotch on opercle and from anterior caudal peduncle to caudal-fin margin (faint stripe continuously from snout to caudal-fin margin in some paratypes). Fins transparent, except for brownish middle of caudal fin. Distribution and habitat. Terelabrus dewapyle sp. nov. is distributed in the western Pacific Ocean where it has been recorded from southern Japan (Iou-jima), Papua New Guinea and Fiji on the basis of collected specimens (Fig. 3) and from Indonesia (Bali: Kuiter 2012; Nusa Penida: Allen & Erdmann 2012) and Japan (Yaku-shima: Motomura & Matsuura 2010; Kochi: Kuiter 2012, Nishiyama & Motomura 2012) as T. rubrovittatus on the basis of underwater photographs. The type specimens were collected at depths of 72– 99 m. The new species has been observed from spring to early summer at recreation diving depths in Kashiwa-jima, Kochi, Japan. The species is epibenthic on sandy, rubble and coral bottoms, with individual males sometimes accompanied by a small harem (K. Nishiyama, pers. comm.). The species is most commonly seen at depths of 65– 70 m during cold upwelling events (temperatures of 20–24 C°) and adults have been observed to dive into the burrows of other organisms when startled, at Menjangan and Nusa Penida islands off Bali, Indonesia (M. Erdmann, pers. comm.). T. dewapyle sp. nov.

The proposed name is a conjunction of the surnames of Mr Shin-ichi Dewa and Dr Richard L. Pyle who collected all type specimens of this new deepwater species. It is treated as a noun in apposition. Kuiter (2012) and Allen & Erdmann (2012) described this species (as T. rubrovittatus) as “Yellow-stripe Hogfish” and “Red-striped Wrasse” respectively. Because true T. rubrovittatus does not have a distinct yellow strip on the lateral surface of the body and its name means “red stripe” in Latin, we herein propose “Yellow-striped Hogfish” for T. dewapyle and “White-striped Hogfish” for T. rubrovittatus as their English names. The standard Japanese names “Kisuge-miyabi-bera” and “Amana-miyabi-bera” are proposed for T. dewapyle and T. rubrovittatus respectively, the Japanese name of the genus Terelabrus being “Miyabi-bera zoku”. Remarks. The new species and its only congener, Terelabrus rubrovittatus Randall & Fourmanoir 1998, share the following unique combination of characters among labrids: an elongated body; cylindrical head and anterior body (body depth 12.9–17.4 % SL); large eye (orbit diameter 6.5–10.7 % SL); nearly flat interorbital space; two pairs of large canine teeth anteriorly in each jaw; dorsal fin with 10 spines and 11 soft rays; anal fin with three spines and 12 soft rays; and the lateral line continuous and smoothly curved (Randall & Fourmanoir 1998; this study). Detailed generic characters and phylogenetic relationships of the genus Terelabrus were described by Randall & Fourmanoir (1998). Terelabrus dewapyle sp. nov. is distinguished from T. rubrovittatus by lower counts of scale rows in the longitudinal series (41 or 42 vs. 45–48 in the latter), pored lateral-line scales (39 or 40 vs. 43–45), and gill rakers (12 or 13 vs. 14 or 15), and a greater least distance between the anteroventral margin of the orbit and the maxilla [1.2–3.7 % (mean 2.5 %) of SL vs. 0.5–2.3 % (1.6 %); Fig. 4] (Table 1). In addition, the fresh and live coloration of the two species is different (Figs 1, 5). Although adult T. rubrovittatus have 8–10 red, somewhat elongated vertical blotches superimposed on the midlateral red stripe (Fig. 5 A, C) (absent when young; Fig. 5 B), T. dewapyle lacks the blotches on the midlateral red stripe in both adults and young (Fig. 1 A, D, F) and sometimes has more than 20 poorly defined, faint, narrow vertical bars extending below the midlateral red stripe in large adults (Fig. 1 E). Adults of T. rubrovittatus have a broad, vivid yellow band submarginally on the dorsal fin (Fig. 5 A) (pale yellow band, barely seen, in young; Fig. 5 B), whereas T. dewapyle has a transparent dorsal fin in both adults and young (Fig. 1). A space between the upper and midlateral red stripes of T. dewapyle is always vivid yellow (Fig. 1 A, D–F), but that of T. rubrovittatus is always white (Fig. 5). Young individuals of T. dewapyle have a black blotch superimposed on the midlateral red stripe on the opercle (Fig. 1 A, D), the blotch fading with growth (Fig. 1 E); the black blotch may be absent or indistinct in T. rubrovittatus (Fig. 5). Terelabrus rubrovittatus is known only from the holotype (the paratype is herein identified as T. dewapyle) from New Caledonia. Two specimens (KPM-NI 4172, 4340) reported as Terelabrus sp. by Senou et al. (2002) from Hachijo-jima, Izu Islands, Japan were identified here as T. rubrovittatus. An additional three specimens of T. rubrovittatus from Palau, Western Australia and Vanuatu were examined in this study, suggesting that the species is widely distributed in the western Pacific Ocean (Fig. 3). Available specimens of the species were collected in depths of 55– 140 m. Comparative material examined. Terelabrus rubrovittatus: 6 specimens, 37.7–98.5 mm SL.
