A phase separation model for stripes has found good agreement with photoemission experiments and with other studies which suggest a termination of the striped phase in the slightly overdoped regime. Here the model is extended in a number of respects. In particular, a discussion of the nature of the charged stripes is presented, suggesting how density waves, superconductivity, and strong correlations can compete with the quantum size effects inherent in narrow stripes. The anomalous doping dependence of the chemical potential is explained.

Annotation:

This paper presents a global and local tensor sparse approximation (GLTSA) model for removing the stripes in hyperspectral images (HSIs). HSIs can easily be degraded by unwanted stripes. Two intrinsic characteristics of the stripes are (1) global sparse distribution and (2) local smoothness along the stripe direction. Stripe-free hyperspectral images are smooth in spatial domain, with strong spectral correlation. Existing destriping approaches often do not fully investigate such intrinsic characteristics of the stripes in spatial and spectral domains simultaneously. Those methods may generate new artifacts in extreme areas, causing spectral distortion. The proposed GLTSA model applies two ℓ 0 -norm regularizers to the stripe components and along-stripe gradient to improve the destriping performance. Two ℓ 1 -norm regularizers are applied to the gradients of clean image in spatial and spectral domains. The double non-convex functions in GLTSA are converted to single non-convex function by mathematical program with equilibrium constraints (MPEC). Experiment results demonstrate that GLTSA is effective and outperforms existing competitive matrix-based and tensor-based destriping methods in visual, as well as quantitative, evaluation measures.

Annotation:

The surface morphology of the anodic aluminum oxide (AAO) prepared with different surface coating has been studied by AFM and SEM. Under optimized condition, highly ordered stripe patterns have been obtained. These regular patterns, including random stripes and regular stripes, show strong dependence on the crystal orientation of the aluminum substrate. This method can be developed into a novel nanoscale fabrication technique.

Annotation:

The entire functional even-skipped locus of Drosophila melanogaster is contained within a 16 kilobase region. As a transgene, this region is capable of rescuing even-skipped mutant flies to fertile adulthood. Detailed analysis of the 7.7 kb of regulatory DNA 3′ of the transcription unit revealed ten novel, independently regulated patterns. Most of these patterns are driven by non-overlapping regulatory elements, including ones for syncytial blastoderm stage stripes 1 and 5, while a single element specifies both stripes 4 and 6. Expression analysis in gap gene mutants showed that stripe 5 is restricted anteriorly by Kruppel and posteriorly by giant, the same repressors that regulate stripe 2. Consistent with the coregulation of stripes 4 and 6 by a single cis-element, both the anterior border of stripe 4 and the posterior border of stripe 6 are set by zygotic hunchback, and the region between the two stripes is ‘carved out’ by knirps. Thus the boundaries of stripes 4 and 6 are set through negative regulation by the same gap gene domains that regulate stripes 3 and 7 (Small, S., Blair, A. and Levine, M. (1996) Dev. Biol. 175, 314–24), but at different concentrations. The 3′ region also contains a single element for neurogenic expression in ganglion mother cells 4–2a and 1–1a, and neurons derived from them (RP2, a/pCC), suggesting common regulators in these lineages. In contrast, separable elements were found for expression in EL neurons, U/CQ neurons and the mesoderm. The even-skipped 3′ untranslated region is required to maintain late stage protein expression in RP2 and a/pCC neurons, and appears to affect protein levels rather than mRNA levels. Additionally, a strong pairing-sensitive repression element was localized to the 3′ end of the locus, but was not found to contribute to efficient functional rescue.

Annotation:

The ‘maccullochi species group’ of rainbowfishes are small and distinctly patterned freshwater fishes of streams and swamps, comprising around eight species. The species from which the group bears its name, Melanotaenia maccullochi Ogilby, 1915, has been thought to comprise three forms occurring in distinct geographic areas, and recent mitochondrial genetic data provides matching patterns of likely inter-specific divergence. Here we undertake a detailed investigation of the taxonomic status of M. maccullochi using a combined lines of evidence approach incorporating multiple nuclear genetic markers (55 allozyme loci), mitochondrial DNA sequence data (1141 bp cytochrome b) and morphology (examination of a suite of 38 morphometric and meristic characters). As all three datasets provide support for a three-way split, we accordingly describe two new species and redescribe M. maccullochi sensu stricto. McCulloch’s Rainbowfish M. maccullochi, a species with brown body stripes and red fins occurs in northeast Queensland and is redescribed based on 338 specimens, 13.1–53.0 mm SL. This species was one of the first rainbowfishes to become known in the aquarium hobby. A second form with darker stripes on a contrasting light white-grey body and with distinct sub-marginal black bands in the dorsal and anal fins, distributed across northern and eastern Cape York Peninsula, Torres Strait and southern central New Guinea, is described as Sahul Rainbowfish M. sahulensis sp. nov. based on 267 specimens, 13.4–48.4 mm SL. A diminutive and well geographically isolated form occurring below the escarpment of the Tabletop Range in Litchfield National Park, Northern Territory possessing a more prominent and purplish mid-lateral stripe, is described as the Little Rainbowfish Melanotaenia wilsoni sp. nov. based on 50 specimens, 19.3–33.3 mm SL. A combination of morphological characters is useful for separating the respective taxa with M. wilsoni sp. nov. the most distinctive, typically having fewer vertebrae, lateral scales, cheek scales, procurrent caudal rays and anal rays and proportionally a shorter maxilla and snout than either of the other two species. Useful characters for further separating M. sahulensis sp. nov. from M. maccullochi include slightly higher counts of vertebrae, lateral scales and anal rays and proportionally greater body depth, body width and pre-dorsal distance. Information on the known distribution, habitats and conservation status of the three species is summarised, with the Northern Territory species being a narrow-range endemic with specific environmental requirements.

Corcyrogobius pulcher is distinguished from its two congeners by having the rear edge of the jaws ending posteriorly below mideye, second dorsal fin I/9, pectoral fin rays 17, pelvic fins oval or truncated posteriorly, scales in lateral series 26–27, anterior oculoscapular head canal with pore β, suborbital row b of sensory papillae anteriorly beginning below vertical of posterior edge of eye, dark vertical caudal bar, branchiostegal membrane without intense dark spot, cheek with two oblique whitish stripes, the first going from the eye downwards and forward to the posterior jaws, the second on the preopercular, alternating with brown oblique stripe going from behind the eye downwards and forward across the cheek. Furthermore, mitochondrial COI-barcoding data unambiguously support the species-level distinctiveness of the three Corcyrogobius species. A key to the species of Corcyrogobius is provided.

Annotation:

Nothobranchius nikiforovi, a new species known from seasonal habitats in the lower Matandu drainage in south-eastern coastal Tanzania is described. It is distinguished from all other congeners, except N. eggersi, by males presenting two colour phenotypes: the blue phenotype having a bright iridescent light blue to blue-green body, with narrow red-brown scale margins creating irregular reticulated pattern, forming chevron-shaped crossbars on the posteroventral portion of body and light blue median fins with red-brown dotted pattern; the red phenotype has a dark red head, light blue dorsal and anal fins proximally and medially, dark red distally, with dark red stripes parallel to the fin rays, and a plain dark red caudal fin. Nothobranchius nikiforovi differs from N. eggersi by male colour pattern, the blue phenotypes having median fins with dark grey distal portion, some of the rays of dorsal and anal fins with white tips (vs. median fins with distinct slender white distal band), and the caudal fin lacking a spotted pattern (vs. dots arranged into irregular curved stripes); the red phenotype with golden stripe between the nape and dorsal-fin origin (vs. light-blue stripe), the dorsal and anal fins with a plain red distal portion and lacking a light distal band (vs. with distinct narrow white distal band), the pelvic fin lacking a distal band (vs. with distinct slender light blue to white distal band), and some morphometric differences. Phylogenetic analyses also support the genetic distinction of the new species from its closest known relative, N. eggersi, and confirm its position in the N. guentheri species group within the Adiniops subgenus.

Annotation:

The human visual system uses a-priori constraints for the estimation of surface shape from images. We propose here a robust paradigm to study individual observers' assumptions about the illuminant and viewpoint positions. In the study of illumination, the stimuli consisted of parallel, sinusoidally shaped, striped regions, alternating between wide and narrow. Narrow stripes alternating between white and black separated the uniform grey stripes, representing slanted edges in light and in shadow. The stimulus had the shape-from-shading ambiguity: either the wide or the narrow stripes could be seen as ‘in-front’, consistent with different assumed tilts of the illuminant. In a brief flash of a randomly oriented stimulus, observers stated whether the narrow or wide stripes appeared in the foreground. The results showed a strong bias for a light-from-above-left assumption (as in Howard et al, 1990 Perception19 523 – 530; Sun and Perona, 1996 Investigative Ophthalmology and Visual Science37 935). This bias was 20 to 30 deg to the left of vertical. Slower reaction times were obtained for more ambiguous figures. The same shape judgment task was used with an unshaded stimulus where the only depth cue was image contour. The same curvy, striped figure was portrayed with image contours at the edges of the stripes, as well as surface markings orthogonal to the depth variation, resulting in a shape-from-contour cue. We have previously reported indirect evidence for a bias of viewpoint above the object, that is observers interpret surface normals as pointing upward (Mamassian, 1995 Perception24 Supplement, 35). Our observers' shape judgments were consistent with this bias.

Annotation:

even-skipped (eve) has been proposed to set up parasegment borders at the anterior edge of each of its seven stripes by providing a sharp expression boundary, where engrailed is activated on one side and wingless on the other. By expressing bell-shaped early eve stripes without the sharp boundary provided by narrow, late stripes, we find that the early gradient is sufficient for generating stable parasegment borders. Based on several lines of evidence, we propose that the anterior portion of each early stripe has morphogenic activity, repressing different target genes at different concentrations. These distinct repression thresholds serve to both limit and subdivide a narrow zone of paired expression. Within this zone, single cell rows express either engrailed, where runt and sloppy-paired are repressed, or wingless, where they are not. While the early eve gradient is sufficient to establish parasegmental borders without refined, late expression, late eve expression has a role in augmenting this boundary to provide for strong, continuous stripes or engrailed expression. In addition, we show that the early eve gradient is sufficient, at its posterior edge, for subdividing the ftz domain into engrailed expressing and non-expressing cells.

Glyptothorax gopii, a new sisorid catfish, is described from the Kaladan River drainage in Mizoram, northeast India. It is distinguished from its congeners in the Indian subcontinent by the combination of the following characters: an axe-shaped anterior nuchal plate element extensively in contact with the posterior nuchal plate, plicae present on the ventral surfaces of the pectoral-fin spine and outer rays of pelvic-fin rays, an elliptical thoracic adhesive apparatus, the nasal barbel not reaching the anterior margin of the eye, tuberculate skin, and two pale cream longitudinal stripes on the body. Glyptothorax alaknandi is considered a valid species.

Annotation:

Maldivea Gerlach, 1962 is a possible endemic genus of the Maldivian archipelago for which only M. xarifae Gerlach, 1962 has been described so far. A new species of this genus, M. complexa n.sp., was recently found in Felidhoo atoll. It reveals a more complex structure of gubernaculum than in type species which appears to be divided into two pieces: one is a sort of long wing in the ventral part of the spicule and the other one, more complex, is characterized by several curved stripes which envelop the dorsal side of the spicule distal part. According to the present considerations, diagnoses of Paroxystomininae and Maldivea are emended.

Annotation:

High-resolution, high-energy, X-ray diffraction results are presented for the study of weak charge ordering phenomenon. By utilizing X-rays in the 100 keV region the dramatic increase in the penetration depth allows for both bulk-sensitive and high-resolution measurements to be made. The strontium doped La 2 NiO 4 system is a prototypical system in the understanding of strong electron-phonon coupling, and the resultant effects on material properties. At doping levels of 1/3 and 1/2 commensurate charge modulations are observed indicating real-space charge stripes. We have measured the correlation lengths of these charge stripes using both 100 keV X-rays and 8.3 keV X-rays. In comparing our results we have observed that the charge stripes appear to be well correlated in the near-surface region with correlation lengths ξ≈2400Å. However, our bulk sensitive measurements show that the charge stripes appear in a possible stripe glass phase with a correlation length of only ξ≈300Å. Our measurements on the 3D charge order manganite system Nd 0.5 Sr 0.5 MnO 3 show that the charge ordering appears to be well correlated in the bulk of the sample in contrast to our nickelate results.

Annotation:

The white-lipped tree viper, Trimeresurus albolabris Gray, is one of the most common species of the genus Trimeresurus with a wide distribution from India eastwards to China and southwards to Indonesia. However, this species was previously split into five geographical clades with significant genetic divergence. Recent surveys in Yingjiang County, Yunnan Province, China resulted in the discovery of one cryptic species of the subgenus Trimeresurus. Combining molecular, morphological and ecological data, we describe it as a new species Trimeresurus caudornatus sp. nov. The new species differs from other Trimeresurus species by a combination of the following characteristics: (1) Head and body generally dark green, postocular stripes absent in both genders, upper labials light green; (2) ventrolateral stripe faint green yellow, present on the first row of DSR in both genders; (3) iris golden yellow in both genders; (4) dorsal tail mostly dark red, lateral and ventral green; an orange red stripe along the ventral part of the tail; (5) DSR 21/22 –21–15, VEN 161–163, SC 52–72; (6) first upper labial partially fused to the nasal. The new species was shown to be a strongly supported monophyletic group (BPP 100%) and sister to T. septentrionalis. The uncorrected pairwise distances of mitochondrial gene Cytb between the new species and other species of the subgenus Trimeresurus, ranging from 0.059 (T. septentrionalis) to 0.134 (T. kanburiensis).

Annotation:

In traditional grating auto-stereoscopic displays,the head movement would lead to the crosstalk of 3D images. There is a way to minimize the crosstalk from utilizing eyes’ position to rearrang the RGB sub-pixels.In this paper, a method to detect the center of eyes which is based on black and white binary grating projection is proposed. After projecting periodic grating composed by black and white stripes from projector,the CCD intakes deformed stripes,using the offset which is compared the deformed fringe with the reference to restore facial contours. Recover the morphology conveniently from encoding every deformed stripe with an unique code. Experimental results show that this method requires less image,has strong anti-interference abilitity.It is easy to get the position of eyes’center after getting the face contour,so this method could be applied as a new way in the nose and face recognition and tracking fields.

Annotation:

We calculate for La2CuO4the phonon-induced redistribution of the electronic charge density in the insulating, the underdoped pseudogap, and the more conventional metallic state as obtained for optimal and overdoping, respectively. The investigation is performed for the anomalous high-frequency oxygen bond-stretching modes, which experimentally are known to display a strong softening of the frequencies upon doping in the cuprates. This most likely generic anomalous behaviour of these modes is shown to be due to a strong nonlocal electron-phonon interaction mediated by charge fluctuations on the ions. We demonstrate that the softening of the modes is caused by nonlocally induced dynamic charge inhomogeneities in form of charge stripes along the CuO bonds with different orbital character. The dynamic charge inhomogeneities may in turn be considered as precursors of static charge stripe order as recently observed in in a broad range of doping around . The latter may trigger a reconstruction of the Fermi surface into small pockets with reduced doping. We argue that the incompressibility of the orbital and simultaneously the compressibility of the orbital in the pseudogap state seem to be required to nucleate dynamic stripes.

Two new leech species (Hirudinida) representing the families Glossiphoniidae (Glossiphonia balcanica n. sp.) and Erpobdellidae (Dina prokletijaca n. sp.) are described. The populations from Montenegro assigned by Utevsky et al. (2013) and Grosser et al. (2015) to Glossiphonia nebulosa Kalbe, 1964 represent an new species, here described as G. balcanica n. sp. The new species can be easily be separated from Glossiphonia nebulosa by the reduction of the papillae. Dina prokletijaca n. sp. closely resembles D. dinarica Sket, 1968 and D. montana Sket, 1968 from which can be distinguished in the combination of the small and stocky body, dorsal surface with two wide and dark paramedian longitudinal stripes and ovisacs reaching the fourth somite after the female genital pore, and curled in their entire course. A key to the species of Glossiphonia Johnson, 1816 and Dina R. Blanchard, 1892 from the Western Balkans is presented.

Annotation:

We argue that the usual Hubbard's model produces only s-wave pairing functions and, even then, only at unphysically large values of the lumped parameter J≡4t2/U. It follows that a reliable theory of high-Tc superconductivity has to include additional features if it is to reproduce the d-wave gap. We test the effects of an alternating potential caused by a charge stripe, on the ground state of the Hubbard model in strong-coupling. If we "fine tune" we do find the d-waves. However, a better-formulated version of a three-band model yields a sturdier theory of pair formation in high-Tc superconductivity. The coupling constant g1=t2/V factors out, hence it serves only to establish the unit of energy; the underlying Hamiltonian is universal. We outline the principal properties of this model, including the intimate relation between charge-density stripes and the d-wave pair function, its rejection of 45° stripes (checkerboard pattern), and other concerns.

Annotation:

The New Zealand diplodactylid gecko genus Toropuku is currently monotypic, but the sole member of the genus, T. stephensi, is distributed in two disjunct, geographically distant regions of New Zealand – the islands of Cook Strait (which includes the type locality, Stephens Island), between New Zealand’s North and South Islands, and the Coromandel Peninsula, in the northeastern North Island. Previously published phylogenetic results, based on three total individuals, recognized substantial—possibly species-level—diversity between these disparate localities, although no taxonomic decisions were made at that time. More recently, additional animals have been found on the Coromandel Peninsula. We here present phylogenetic and morphological evidence based on this expanded dataset to formally describe the populations on the Coromandel Peninsula as a new species, Toropuku inexpectatus sp. nov. The specific epithet refers to the species’ surprise discovery in a herpetologically well-surveyed area. The recognition of T. inexpectatus sp. nov. as a distinct species has implications for the conservation status of T. stephensi, which is now considered restricted to three islands in Cook Strait.

Stripe noise is a common condition that has a considerable impact on the quality of the images. Therefore, stripe noise removal (destriping) is a tremendously important step in image processing. Since the existing destriping models cause different degrees of ripple effects, in this paper a new model, based on total variation (TV) regularization, global low rank and directional sparsity constraints, is proposed for the removal of vertical stripes. TV regularization is used to preserve details, and the global low rank and directional sparsity are used to constrain stripe noise. The directional and structural characteristics of stripe noise are fully utilized to achieve a better removal effect. Moreover, we designed an alternating minimization scheme to obtain the optimal solution. Simulation and actual experimental data show that the proposed model has strong robustness and is superior to existing competitive destriping models, both subjectively and objectively.

Here, we describe Theretra makhrovi sp. nov., a new hawk moth species from Flores Island, East Nusa Tenggara, Indonesia. This species is most similar to Theretra acuta Vaglia & Liyous, 2010 and T. rhesus (Boisduval, [1875]) but can be distinguished from these taxa by the lack of several marking features such as narrow yellow stripes on the tegula, a large, triangular black spot on the underside of the forewing, and a clear zigzag curved band on the underside of the hindwing. The new species has pink shading on the underside of both wings that is absent in the two other species. It also has narrower and longer wings and specific male genitalia structure compared with the two similar taxa.

Annotation:

The nemacheilid genus Seminemacheilus is revised. Six species are recognised, three of them described herein as new. All species are endemic to Central Anatolia. Seminemacheilus lendlii from the Sakarya River drainage and the endorheic Lake Aksehir and Eber basins, S. ispartensis from Lake Eğirdir basin and S. ahmeti from Sultan Sazlığı are valid species. Although Seminemacheilus lendlii and S. ispartensis have almost identical COI sequences, they are distinguished by the shape of the caudal peduncle and the presence of scales on the caudal peduncle in S. ispartensis (vs. absent in S. lendlii). Seminemacheilus attalicus, new species, from Kırkgöz drainage, is distinguished by having a slightly emarginated caudal fin, a central pore in the supratemporal canal and a marbled flank pattern. Seminemacheilus ekmekciae, new species, from Lake Tuz basin is distinguished by having a roundish caudal fin, a short post-dorsal length and large brown blotches fused into stripes on the flank. Seminemacheilus tubae, new species, from Lake Beyşehir basin, is distinguished by having a truncate caudal fin and 2–5 (6) supraorbital head pores. Seminemacheilus dursunavsari from the Göksu River drainage is not a valid name and this population is identified as S. tubae.

The spectro-temporal ripple for investigating processor effectiveness (STRIPES) test is a psychophysical measure of spectro-temporal resolution in cochlear-implant (CI) listeners. It has been validated using direct-line input and loudspeaker presentation with listeners of the Advanced Bionics CI. This article investigates the suitability of an online application using wireless streaming (webSTRIPES) as a remote test. It reports a strong across-listener correlation between STRIPES thresholds obtained using laboratory testing with loudspeaker presentation vs remote testing with streaming presentation, with no significant difference in STRIPES thresholds between the two measures. WebSTRIPES also produced comparable and robust thresholds with users of the Cochlear CI.

Annotation:

We describe a new species of Zhangixalus from southern Yunnan of China, Vietnam, and Thailand based on morphological and molecular evidence. The new species had been confused with Zhangixalus smaragdinus (Blyth, 1852) in the past. Zhangixalus pachyproctus sp. nov. can be distinguished from Z. smaragdinus morphologically by the protruding vent in adult males, large thick grey reticular mottles below the white stripe on flank, more oblique snout in profile and wider head, longer snout, greater internarial distance, larger tympanum and longer hindlimb. The new species can be distinguished from other species of Zhangixalus with green dorsum by the following combination of characters: body size larger (SVL of adult males: 74.2–83.3 mm; SVL of adult female: 102.4 mm); dorsum smooth; narrow white stripes along edge of the lower jaw, body sides, outer side of limbs and above the vent; absence of brown bands on canthus rostralis, upper eyelid and supratympanic fold; webbing between fingers and toes complete except between the first two fingers; and internal single subgular vocal sac. Phylogeny based on comparison of 16S rRNA sequences suggests that the new species is the sister taxon to Z. smaragdinus and the two species differ by 7.63% in the uncorrected pairwise distance of 16S sequences.

Annotation:

Recent investigations in the context of the standard and extended t-J models using computational techniques are here described. In regimes of couplings producing a one-hole dispersion compatible with photoemission data for the parent insulator, the one-hole states have strong antiferromagnetic correlations across-the-hole, particularly at momenta (0,π)-(π,0). This effect is rationalized as a tendency toward spin-charge separation in two-dimensions at short distances. At finite hole density, doped stripes are observed. The elementary building block of the stripes resembles the spin arrangement around individual holes. This suggests that the seed of doped stripes already exist in the unusual properties of the insulating parent compound. Stripes are conjectured to originate in a "frustrated spin-charge separation" effect, different from other theories valid at large J/t discussed in previous literature.

Studies were conducted in the I. V. Michurin Federal Scientifi c Center and in its Middle Russian branch. For the fi rst time in the North-Eastern part of the Central black earth region, researches are being conducted to study the microbiota of the soil in the garden of pome crops. The aim of this research was to study the micromycetic composition of the soil in the agrocenosis of a multifactorial experience of an intensive apple orchard. Soil samples were taken in the space between rows and near-stem stripes on the sodding, in the space between rows and near-stem stripes on the fallow land. Experimental conditions: 1) control (natural conditions); 2) optimal moisture (irrigation, soil moisture 80 %); 3) waterlogging (irrigation, soil moisture 120 %). As a result of the conducted research, the dependence of the number of phytopathogenic and saprotrophic populations on the elements of agrotechnology was shown. The maximum number of the population was marked in the near-stem stripes on the fallow land and the minimal number was marked in the near-stem stripes on the sodding. The eff ect of moistening on the number of soil micromycetes was revealed. 80 % moisturized sodded space between rows and near-stem stripes, space between rows on fallow land at a humidity of 120 %, and near-stem stripes with 80 % moisture contained a high number of phytopathogens in relation to natural conditions. The greatest species diversity of the soil mycobiota was observed in the sodded near-stem stripes. A strong correlation was established from reverse close (r = -0.98) to positive close (r = 0.83) in relation to the phytopathogens and saprotrophs in the sodded row spacing; in the soil of the sodded near-stem stripes – from close negative (r = -0.90) to close positive (r = 0.92). It was noted that soil mites did not tolerate the over moistened soil, nematodes, on the contrary, were activated in soils with a humidity of 80 % and 120 % in sodded row spacing. The correlation between nematodes and soil mites in all variants remained strong (r = 0.86-0.97), closer in the control. The number of micromycete organisms in the soil was determined by a modifi ed fl otation method. In the course of research, 1 ml of distilled water was added at one of the stages, instead of a 0.1 % solution of potassium pyrophosphate; on the other, 29 ml of 0.1 % potassium pyrophosphate solution was added instead of 29 ml of distilled water.

Tachysurus spilotus, a new species of catfish from central Vietnam, is described. It can be distinguished from congeners except T. argentivittatus, T. longispinalis, and T. virgatus in having a color pattern consisting of black longitudinal stripes on a pale body (vs. with a uniform-colored body with pale patches or transverse bands on a dark body, or with dark rectangular patches on a pale body). It differs from both T. argentivittatus and T. virgatus in snout shape and having gently convex (vs. straight) posterior edges of the caudal-fin lobes; and from T. longispinalis in having a shorter dorsalfin spine (ca. 27% SL vs. 15.1–19.0) and maxillary barbels (shorter, vs. longer than head). Tachysurus mica is shown here to be conspecific with—and a junior synonym of—T. argentivittatus.

Annotation:

AbstractSmall anomalies in ice-shelf surface temperature correlate with measured microtopography. Clear-sky thermal infrared (TIR) images of the Brunt Ice Shelf, Antarctica, frequently show persistent patterns of anomalous snow surface temperatures. The anomalous signatures appear as stripes orientated along the ice flowline and are of the order of 5 K in magnitude. The positional persistence of the stripes suggests a topographic mechanism for their formation. In order to test this hypothesis, the TIR stripes are compared to a digital terrain model (DTM) derived from a kinematic global positioning system survey of the ice shelf. Ridges and valleys are seen in the DTM; the ridges correspond to the warmer TIR stripes, the valleys to the colder areas. In order to investigate the mechanism that couples elevation with thermal signature, two comparable but contrasting sets of clear-sky infrared images are presented, along with surface meteorological data. The first shows strong TIR stripes, whilst the second, despite similar snow- and air-temperature profiles, shows a weaker signature and smaller sensible-heat flux, H. Two possible mechanisms are presented which explain the TIR signature: surface elevation mapping onto the vertical air-temperature profile or, alternatively, enhanced surface sensible-heat flux on elevated areas. At present, there is insufficient information to resolve this uncertainty.

Annotation:

The use of color photographs in crayfish species descriptions, state faunal books and popular articles is relatively recent. Except for verbal color descriptions, color and color patterns have not often been explored by crayfish researchers. Carotenoids and carotenoproteins are responsible for much of the color found in the integument and exoskeleton of crayfishes and other crustaceans. Research has shown variation in color may be the result of the environment, diet, molt stage and age, genetics, or a combination of these. Crayfishes possess color vision, may use polarization vision, and have the possibility of fluorescent vision. They also have very good low light vision. Crayfishes have a multichromatic range in color sensitivity; it ranges from blue to red, with no UV sensitivity. Color vision may be an important factor in intraspecific and interspecific competition, territoriality, camouflage, sexual selection, and communication. A distinction is made between base or background colors displayed in crayfishes and their exhibited color patterns. While actual base or background colors may vary among individual crayfishes, a case is made that color patterns show much less intraspecific variation. Distinct color patterns are the result of highly contrasting colors on appendages or parts of appendages such as chelae, leg joints, tail fan, spines, and tubercles. Body regions like the carapace and abdomen may also have contrasting spots, bands or stripes. Color patterns may be useful in better understanding crayfish taxonomy, phylogeny, and evolutionary convergence, and examples are provided.

Adult frogs in this group are morphologically similar, generally dark-bodied with yellow dorsolateral stripes, orange flash marks and some also possessing bright-yellow dorsal spots. Despite considerable research on their breeding behavior, acoustics and systematics (Lötters et al., 2009; Forti et al., 2013), the tadpole of Ameerega boehmei, the southern-most and western-most distributed species in this tentative group, has not been described.

Studies of the transport properties of a Sn superconducting film with several (1–7) parallel nickel magnetic nanostripes deposited on the top of a thin Ge insulating layer covering the surface of the superconducting film are reported. Measurements of the dependence of the resistance on the in-plane magnetic field with two magnetic field orientations (parallel to the stripes direction and perpendicular to the stripes) and the temperature have been made. We have studied resistance versus in-plane magnetic field direction. Different types of strong hysteresis in the resistance dependence on the magnetic field for different magnetic field orientations were observed.

Annotation:

A new species of Entomobrya Rondani: E. tristriata sp. nov., from Jilin, one province of the Northeast China and first record of Entomobryoides sotoadamesi Jordana, Potapov & Baquero, 2011, are herein described. Entomobrya tristriata sp. nov. is characterised by three longitudinal dark blue stripes from Th. II to Abd. III, prelabral smooth chaetae and larger subapical tooth on mucro. However, in most species of Entomobrya, prelabral chaetae are ciliated and subapical tooth is subequal to the apical one. Entomobryoides sotoadamesi was first described from Far East of Russia and Chinese specimens agree with the original description.

Annotation:

We describe two new Kukri snakes of the genus Oligodon from the Nakhon Si Thammarat Mountain Range, southern peninsular Thailand. Oligodon phangan sp. nov., endemic to Pha-Ngan Island, Surat Thani Province, is characterized by a maximal known SVL of 369.1 mm; 12 maxillary teeth, the posterior three enlarged; 17-17-15 dorsal scale rows; 163–166 ventrals; 33–42 divided subcaudals; a single anal; dorsal color brown with a pair of discreet paravertebral and lateral stripes; no dorsal or supracaudal bands, blotches or crossbars; background color of belly pinkish-orange; underside of tail immaculate. Oligodon promsombuti sp. nov., whose type-locality is Khao Phanom Wang, Surat Thani Province, is also found in Trang Province, and is characterized by a maximal known SVL of 552.7 mm; 12 maxillary teeth, the posterior three enlarged; 17-17-15 dorsal scale rows; 177 ventrals; 40 divided subcaudals; a single anal; deeply forked hemipenes lacking spines; dorsal color blackish brown with nearly indistinct paravertebral stripes; no dorsal or supracaudal blotches or crossbars; background color of belly ivory, heavily speckled with subrectangular blackish blotches. We tentatively allocate both new species to the informal Oligodon-cyclurus-group. They are the 5th and 6th Oligodon species endemic to Thailand. We add Oligodon ocellatus, so far known only from Cambodia, southern Laos and southern Vietnam, to the Thai fauna, based on a specimen from Chong Mek, Ubon Ratchathani Province.

Annotation:

A new Corydoras is described from the rio Juruena system, upper rio Tapajós drainage, Amazon basin, Brazil. The new Corydoras is distinguished from all congeners by presenting a combination of a conspicuous broad vertical dark bar on head, at the level of the eye (mask), an overall light background color without large blotches or stripes on body or fins, the presence of two to four small dark blotches along the midline, and pectoral spine with antrorse serrations on its posterior margin. Males of the new species possess numerous, well-developed odontodes over the lateral portions of head, pectoral girdle, and pectoral spines, an uncommon feature for the genus. The new species is hypothesized to belong, within the genus Corydoras, either to Lineage 6 or Lineage 9.

Annotation:

Three species of geckos in the genus Goniurosaurus have been recorded from Hainan Island in China. We describe a new species, Goniurosaurus kwanghua sp. nov. Zhu & He, bringing the number of this genus in Hainan Island to four. We conducted phylogenetic analyses with two mitochondrial genes (16S & Cytb) and two nuclear genes (RAG1 & C-MOS) to validate this new species. The new species is similar to G. hainanensis, but differs in the following characters: (1) middle section of the nuchal loop wide and posteriorly protracted, (2) wider body bands with dark markings, (3) yellow stripes on posterior side of humerus and femur, linked to the first and third body bands, respectively. The type specimens are deposited in the Museum of Biology, East China Normal University (ECNU).
