Species of Photonectes, subgenus Photonectes s. str. (Prokofiev 2019: 393), unique in postorbital organ shifted forward below orbit, blue luminous tissue on body arranged in two widely spaced interrupted lines between IV photophores and streak-like patch on each side above 10 th to 13 th PV photophores (Figs. 1, 2), and mental barbel with pair of stalked photophore-like structures on distal extremity of its stem (Fig. 3). Description. Measurements, vertebral, and fin element counts are shown in Table 1. Snout moderate, 1.3 times smaller than eye. Dorsal and anal fins opposed, shifted backward; pelvic fins inserted closer to caudal fin than to snout. Medial fins not covered by skin; pelvic and caudal fins broken at tips. Photophores: BR 9, IP 11 (interspaces between posteriormost three IP photophores approximately 1.5 times greater than previous ones), PV 21, IV 32, OV 20 or 21, VAV 13 (3 over anal-fin base), VAL 11 (2 over anal-fin base), AC 12, IC 57. Blue luminous tissue on body arranged as described for holotype (Prokofiev & Frable 2021) (Figs. 1, 2), but streak-like patch above PV photophores is slightly longer and situated above 10 th to 13 th photophores in two smallest specimens (64–68 mm SL) with two small faint round patches posteriorly also not present in larger specimens (Fig. 1C). In specimen SIO 76-6, blue luminous tissue in pectoral area is more developed than in other specimens, forming elongate patch originating above IP-11 and ending midway between PV-2 and PV-3 photophores (Fig. 1A, B). Postorbital organ long, its anterior half situated below eye (Fig. 1A). Jaw dentition heterogeneous; premaxillary dentition biserial, with 2 teeth in outer row and 7–8 teeth in inner row; teeth in outer row and first tooth in inner row small and pointed, remaining inner teeth long, of unequal size, with barbed tips. Outer premaxillary teeth opposite bases of second and third teeth of inner row. Maxilla bears 7–8 moderately long, unequal-length teeth with barbed tips, followed by 9–12 smaller, inclined, comb-like teeth with pointed tips. Lower-jaw teeth 26 (SIO 76-6 and USNM 320468) or 23+/26 (USNM 258733), tips of longer teeth barbed. Vomer with 1 or 2 teeth on each side (anterior largest, posterior potentially a replacement), palatine teeth absent. Basibranchial teeth with two tooth patches, anterior patch with two pairs of sharp conical teeth, posterior patch with two or three pairs of teeth. First ceratobranchial with 7 clusters of denticles, from 1–3 each. Gill filaments of first ceratobranchial not reduced, similarly developed along whole length of bone. Posterior process of anguloarticular well-developed. Barbel 1.2–1.6 times in head, with thick pigmented stem and thin unpigmented terminal filament ending in bulbous swelling (Fig. 3) (missing in SIO 76-6). Terminal filament is 1.9–2.3 times longer than stem. Distal extremity of stem unpigmented and possibly luminous, base of luminous tip with internal black pigmentation and pair of stalked photophore-like organs, not as pronounced in SIO 76-6. Remarks. In all respects, the new specimens are similar or identical to the holotype of P. klepadloae, showing only slight but invaluable differences in some counts, morphometrics, degree of development of the blue luminous tissue, and in barbel structure. The most obvious is the presence of a bulbous swelling at tip of terminal filament in two smaller specimens, which is lacking in the holotype and SIO 76-6. Most probably, the absence of this swelling is an artifact resulting from damage incurred during the collecting haul, as the tip of the filament looks incomplete in the two larger specimens. The general pattern of distribution of the blue luminous tissue is identical in all specimens, although the size of individual patches is somewhat variable between the specimens. Distribution. Photonectes klepadloae is still only known from the central north Pacific Ocean between 21 to 30° N and 147 to 171° W (Fig. 4).Published as part of Prokofiev, Artem M. & Frable, Benjamin W., 2023, New specimens and supplementary descriptions of two rare dragonfishes Photonectes klepadloae and P. litvinovi, with comments on the distribution of P filipendulus (Teleostei: Stomiidae: Melanostomiinae), pp. 489-500 in Zootaxa 5228 (4) on pages 490-492, DOI: 10.11646/zootaxa.5228.4.7, http://zenodo.org/record/754013
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Many-electron theory of resonant charge transfer: Role of surface states in He and He+ scattering off Si(100)
No full textA many-electron theory of resonant charge transfer, originally formulated for the scattering of an atom with an empty valence orbital from a surface, is extended to treat the case where the valence orbital is initially occupied by one or two electrons. The scattering of He and He+ from the Si(001) surface is investigated. The interaction is assumed to be with the narrow band of surface states, and not the much wider bulk band. As a result, considerable oscillations are found in the ionization and/or neutralization probabilities as a function of the incident energy.PT: J; CR: AMOS AT, 1989, ADV CHEM PHYS, V76, P335 AMOS AT, 1989, SOLID STATE COMMUN, V71, P449 BLOSS W, 1978, SURF SCI, V72, P277 BRAKO R, 1981, SURF SCI, V108, P253 BURROWS BL, 1984, Q APPL MATH, V42, P73 BURROWS BL, 1990, J PHYS A-MATH GEN, V23, P1101 BURROWS BL, 1991, SURF SCI, V253, P365 CHADI DJ, 1975, PHYS STATUS SOLIDI B, V68, P405 HAGSTRUM HD, 1954, PHYS REV, V96, P336 HAGSTRUM HD, 1961, PHYS REV, V122, P83 HERMAN F, 1963, ATOMIC STRUCTURE CAL IHM J, 1980, PHYS REV B, V21, P4592 MUDA Y, 1980, SURF SCI, V97, P283 MUDA Y, 1988, NUCL INSTRUM METH B, V33, P388 MUDA Y, 1988, PHYS REV B, V37, P7048 PAULING L, 1935, INTRO QUANTUM MECHAN ROBERTS N, 1990, SURF SCI, V236, P112 SOUDA R, 1985, SURF SCI, V150, L59 SOUDA R, 1986, NUCL INSTRUM METH B, V15, P114 SOUDA R, 1986, NUCL INSTRUM METH B, V15, P138 SOUDA R, 1986, SURF SCI, V176, P657 SULSTON KW, 1988, PHYS REV B, V37, P9121 SULSTON KW, 1988, SURF SCI, V197, P555 SULSTON KW, 1989, SURF SCI, V244, P543 WEAKLIEM PC, 1990, SURF SCI, V232, L219 WEISENDANGER R, 1990, SURF SCI, V232, P1; NR: 26; TC: 4; J9: PHYS REV B; PG: 11; GA: HZ245Source type: Electronic(1
