Performance analysis of M-QAM scheme combined with multiuser diversity over Nakagami-m fading channels
No full textIn this paper, we consider an M-ary quadrature amplitude modulation (M-QAM) scheme combined with multiuser diversity over Nakagami-m fading channels. Assuming that delayed but error-free signal-to-noise ratio (SNR) feedback is available, we derive closed-form formulas for the average transmission rate and the average bit error rate (BER), which are also shown to be generalizations of many previous results. Through numerical studies and simulations, we check the validity of our analysis. In addition, we investigate the impact of the Nakagami fading parameter m and feedback delay on system performance.This research was supported by the MIC (Ministry of Information and Communication), Korea, under the ITRC (Information Technology Research Center) support program supervised by the IITA (Institute of Information Technology Assessment).

Cone structures and parabolic geometries
No full text© 2021, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.A cone structure on a complex manifold M is a closed submanifold C⊂ PTM of the projectivized tangent bundle which is submersive over M. A conic connection on C specifies a distinguished family of curves on M in the directions specified by C. There are two common sources of cone structures and conic connections, one in differential geometry and another in algebraic geometry. In differential geometry, we have cone structures induced by the geometric structures underlying holomorphic parabolic geometries, a classical example of which is the null cone bundle of a holomorphic conformal structure. In algebraic geometry, we have the cone structures consisting of varieties of minimal rational tangents (VMRT) given by minimal rational curves on uniruled projective manifolds. The local invariants of the cone structures in parabolic geometries are given by the curvature of the parabolic geometries, the nature of which depend on the type of the parabolic geometry, i.e., the type of the fibers of C→ M. For the VMRT-structures, more intrinsic invariants of the conic connections which do not depend on the type of the fiber play important roles. We study the relation between these two different aspects for the cone structures induced by parabolic geometries associated with a long simple root of a complex simple Lie algebra. As an application, we obtain a local differential-geometric version of the global algebraic-geometric recognition theorem due to Mok and Hong–Hwang. In our local version, the role of rational curves is completely replaced by appropriate torsion conditions on the conic connection.11Nsciescopu
Reduction of lattice thermal conductivity in PbTe induced by artificially generated pores
No full textHighly dense pore structure was generated by simple sequential routes using NaCl and PVA as porogens in conventional PbTe thermoelectric materials, and the effect of pores on thermal transport properties was investigated. Compared with the pristine PbTe, the lattice thermal conductivity values of pore-generated PbTe polycrystalline bulks were significantly reduced due to the enhanced phonon scattering by mismatched phonon modes in the presence of pores (200 nm-2 m) in the PbTe matrix. We obtained extremely low lattice thermal conductivity (0.56 W m-1 K-1 at 773 K) in pore-embedded PbTe bulk after sonication for the elimination of NaCl residue. © 2015 Jae-Yeol Hwang et al211Nsciescopu

Hunyadi, A., Murányi, D. and Páll-Gergely, B., 08 August 2016. Remarks In the original description, Hwang (2014) mentioned three differences between Indian B. plicidens and the subspecies Bensonella plicidens lakainguta. The most important of them was the submarginal elevations of columellar, basal and palatal barriers, i.e. anterior to the hooks those barriers become more elevated. However, this trait can also be seen in Indian B. hooki sp. nov. (Figure 9 (c,d)); see differences between B. lakainguta and B. hooki sp. nov. outlined under the description of the latter. Boysidia (Bensonella) qingliangfengensis (Figure 7 (e,f)) was described from the border region of the Chinese Anhui and Zhejiang Provinces (very close to Pilsbry̾s (1917) record from Hangzhou), and is claimed to be larger than B . plicidens, yet looks identical for all other characters. Therefore, it is treated here as a junior synonym of B . lakainguta Hwang, 2014. Maassen (1999) mentioned that he compared Bensonella karoensis with Japanese shells of Bensonella plicidens (= Bensonella lakainguta). Furthermore, he erroneously stated that Bensonella plicidens inhabited Thailand.Published as part of Páll-Gergely, Barna & White, Tom S., 2023, Solving the mystery of the misunderstood Bensonella plicidens (Benson, 1849) (Gastropoda: Stylommatophora: Hypselostomatidae), pp. 2011-2029 in Journal of Natural History 56 (45 - 48) on pages 2025-2026, DOI: 10.1080/00222933.2022.2152750, http://zenodo.org/record/756093

Sexual dimorphism regards size, terminalia and different wing length: female wings terminate above tip of abdomen while male wings do not cover terminal segments; shortened male wing has less crossveins but branching Radial vein. Setation generally short and dense. General colour dark brown, contrasting pale pattern on wings and appendages. Head and pronotum entirely dark brown; tentorial callosities and M-line hardly visible, occiput with well developed but not contrasting rugosities (Fig. 11). Eyes and ocelli black and small, ocelli located far from each other, in a regular triangle.Antenna as long as the length of body, with more than 45 slightly clubbed antennomeres. Scape bicolored: base and inner edge dark brown, apex and outer edge light brown; pedicel and the next few antennomeres are light brown, gradually darkened towards dark brown two thirds of the antennae. Palpi brown, mouthparts mostly dark brown but glossa, paraglossa and apex of labrum contrastingly pale; vestigial submental gills present (Fig. 4). Pronotum rectangular, about as wide as long, edges rounded; rugosities numerous and small. Meso- and metanotum dark brown with whitish membranes around the wing base. Forewing with contrasting pattern: costal area and anal field shiny dark brown with metallic tint, the rest of the remigium off-white; venation brown, darker in the costal area. Hindwing is less contrasting, mostly brown with dark brown costal area (Figs. 2–3). Ventral surface of thorax contrasting: membranous areas white, while sclerotized plates brown to dark brown. Legs long and slender; tibiae distinctly longer than femora, and even more slender; claws symmetrical, arolium large. Femora dark brown with contrasting pale apical ring. Basal third of tibiae dark brown, then gradually lightened towards pale brown apical third. Tarsi light brown to brown but apical half of metatarsi dark brown. Ventral sclerites of thorax (Fig. 1): Prothorax: cervical sclerites large, with bud-like gill vestiges; rounded presternum fused with small basisternum,both with a longitudinal median ridge;precoxal bridge vestigial,eutrochantin well developed; furcasternum large and triangular, fused with basisternum, postcoxal bridge and medially ridged postfurcasternum; the furcasternal area similar to the mesothoracic furcasternum–furcasternal arm–furcasternal pit complex. Mesothorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and triangular, fused with basisternum; furcal pit (furcasternal arm) connecting anteriorly to arm of mesosternal ridge that continued in a long stem (furcasternal pit); areas between furcal pit and stem sclerotized but hardly delimited. Metathorax: anterior thoracal bud-like gill vestiges present; spinasternum vestigial, presternum large and triangular, fused with the small, stripe-like basisternum; trochantin stripe-like; furcasternum large and quadrangular, fused with basisternum; furcal pit connecting to lateral margin of furcasternum; sternum I fused with furcasternum. Wing venation (Figs. 2–3, 5–6): Forewing: Costal field enlarged, with many irregular, often forked or interrupted crossveins between Costa and irregular Subcosta, humeral crossvein not clearly distinguishable. Subcosta joins the unbranched Radial vein before single radiomedial crossvein in the female, well after the branching of Radial vien in the male; there are one or two crossveins between Subcosta and Radial vein, further two between Costa and Radial vein, stigma is lacking. Medial vein originates independently from Radial vein but its base is obscure, the two veins are distinctly separated well before arculus; Medial vein branches into an irregular network shortly after arculus in the female, with several crossveins, and four longitudinal veins reaching wing margin. There are 3–5 mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular, there are 8–9 cubital crossveins in the female, 3–4 in the male; Cu1 ends about the position of Radial vein ending, last 2–3 crossveins end directly in wing margin, Cu2 ends about the position of Subcosta ending. Cubital vein and A1 basally fused, branches at the anal crossvein, cubitoanal crossvein distinct in the female but lacking in the male; A1 strongly curved after the crossveins, ends about half of wing length. There are three further anal veins besides A1; A2 and A3 can be connected with a crossvein, A4 is very short. Hindwing: Enlarged costal field, Costa, Subcosta and Radial vein network is generally similar to forewing, but humeral crossvein can be identified more distinctly. Origin of Medial vein separated from Radial vein, similarly to forewing, but irregular network of its branching is with less crossveins. There are two mediocubital crossveins besides arculus. Cu1 and Cu2 branching before arculus, cubital cell quadrangular but short, there are 5–6 cubital crossveins. Cubitoanal crossvein short and connected to a basal anal cell, there is an additional crossvein between Cu2 and A1 well after half wing length. Anal field very large and as long as the remigium, the fold of the wing extending between the parallel Cu2 and A1. Additional A veins are 7–8, branching irregularly, the last Anal vein gives irregular crossveins towards wing margin. Male abdomen (Figs. 7–8, 19–20): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga I–III with wide, lightly sclerotized medial field, tergum IV with small medial field, terga V–IX entirely sclerotized and unmodified, dark brown; terga I–IX with entire antecosta, lack sensilla basiconica. Tergum X full divided into hemiterga; mostly dark brown, apical portions lighter, lack sensilla basiconica. Hemiterga triangular with rounded apex, the apical halves are converging in dorsal view, and elevated in lateral view; the wide basal anchor of epiproct divides hemiterga in the basal third by more than half of segment width, apices of hemiterga divided by a gap as wide as one fifth of the segment width. Sterna I–VIII brown, gradually darkening towards the apical segments, lacks vesicle. Sternum IX forms a well developed, rounded subgenital plate, covering sternum X and most of paraproct; sternum X widely divided medially. Paraproct dark brown, triangular with narrowed apical half, ending in a blunt apex; eversible portion is lacking. Cercus as long as the length of body, with 22–24 cylindrical segments, apical ones are rather elongated; basal 4–5 cercomeres yellowish, the rest is gradually darkened towards dark brown apical half of the cercus, but each cercomere with pale apical ring. Epiproct (Figs. 7–8, 12–14, 19–20): Basal anchor large and wide, connected to large, posteriorly directed lateral arms with raised tip, stretching basal membranes.The lever arm long and curved, rather wide in dorsal view, separated from the complex epiproct tip. The epiproct tip is shaped like an elongated 8 in dorsal, straight stripe-like in caudal, and half moon shaped in lateral view; most of the surface is lightly coloured but with a wide, lateral dark stripe and a dark dorsal ridge; the apex is arrow-shaped, tip slightly down curved in lateral view, and basally connected to rounded membranous portion. Paragenital plate large and bears ventral projection; stripe-like and slightly curved in dorsal view, dorsal portion darker in lateral view and with down curved apical portion, ventral projection has caudal edge perpendicular to the dorsal portion. Lateral stylet small, not fused and hidden in the cowl in resting condition of the epiproct; curved and stripe-like, apex with a curved, acute tooth. The cowl is densely covered by setae on most of its surface, with the exception of the dorsal surface basally to lateral stylets; bears a distinct, wide field of dense, tiny golden spikes between the stretched lateral stylets, seen only in fully everted position. In everted condition of the epiproct, the lateral arms of basal anchor raised dorsad, as well the rather enlarged cowl and epiproct tip that is fully exposed. Paragenital plates only slightly change posture, holding tight the base of the cowl. The lateral stylets are turning outwards by the base of the epiproct tip, stretching the apex of the cowl into two small, apicolateral lobes, and exposing the field of golden spines in front of the epiproct tip. The everted cowl has no other lobes, its shape is blunt conical in lateral, and rectangular in caudal view. Aedeagus (Figs. 15–16): Shape and lobes of the fully everted aedeagus remained unknown, but surface armatures and certain lobes around the armatures were clearly seen after dissection. On the ventral surface, golden brown scales are forming a large T-shaped loop; the scales are irregular small plaques with raised flanges. Adjacent to the upper part of the T, a pair of small lobules present, while the lower stem of the T is connected to a larger lobe forming an upside down C, bearing a small patch of scales beneath the stem of the T. Both the paired lobules and the lower lobe bear minute colourless spicules, scarce spinules distributed also on the surface beneath lower lobe; the surface lateral and above to the T is rarely wrinkled. The dorsal surface is armed with three small patches of golden scales similar to the ventral surface but no spicules; the upper two, elongated patches are positioned on inverting lobes, while the third, rounded patch is positioned medially on a rounded lower lobe. Female abdomen (Figs. 9–10): Segments I–II are fully divided into terga and sterna by pleura, segment III with shallow posterior notch of pleura, rest of the segments are entire. Terga unmodified, uniformly brown but apical two segments are darker, all with entire antecosta. Sterna I–VII brown, gradually darkening towards the apical segments. Subgenital plate reduced to a very slightly protruded, widely rounded posterior margin of sternum VIII, slightly bulging in lateral view; sternum VIII dark brown, with an inconspicuous longitudinal pale stripe medially. Sterna IX–X unmodified, dark brown but sternum IX with a mediobasal paler area. Paraproct dark brown with paler tip, elongated and narrow triangular, ending in a blunt apex. Cercus nearly as long as the length of body, with 24 cylindrical segments, apical ones are rather elongated; basal 3–4 cercomeres yellowish, the rest is gradually darkened towards dark brown apical two thirds of the cercus, but each cercomeres with narrow, pale apical ring. Egg: No fully matured eggs are available, but one of the females contains several dozens of nearly matured eggs. These are spherical, elongated oval with 0.3–0.4 mm length and 0.2–0.3 mm diameter. The chorion is golden light brown, apparently with dense punctuations of FCIs. No traces of collar or rims can be recognized. Larva: unknown. Affinities: As for the genus. Ecology and distribution: The species was caught by Malaise traps during May, June and July. The traps were set at elevations ranging from 700 to 1300 m, along medium sized forest streams with fast flow and mixed rocky and sandy substrate (Fig. 21). The known localities are located in the Thebaek ranges, in three counties of Gangwon province (Gangwon-do): Inje-gun, Pyeongchang-gun, Jeongseon-gun (Fig. 22). Etymology: The name koreanus refers to the Korean Peninsula where this remarkable stonefly was found.

Scape reaching apex of clypeus; eye hemispherical in dorsal view, less than 1/5 length of head, not attaining ventral margin of head in lateral view. THORAX. Antero-lateral paired projections acute, diverging; median pronotal depression contiguous with transverse sulcus; paramedian carina weakly defined; scutellar process short, apex subacute; mesosternite with setigerous tubercles but no protrusion. HEMELYTRON. Attaining tip of abdomen. LEGS. Same as genus description. ABDOMEN. Elongate ovoid, with rounded terminal margin; connexival margin slightly undulating, posterior margin not elevated. GENITALIA. Not dissected. Male Unknown. Ecology Little known, specimens collected from altitude of 82 m to 549 m (1800 ft). Coloration of specimens differs slightly, but it is unclear whether this is due to natural variation or preservation history. Distribution Found across Northern Borneo from east (Bettotan, Sandakan) to west (Mt. Poi), and also one specimen from Peninsular Malaysia (Perak, Jor Camp). Remarks Physoderes ostenta is synonymized with B. decora comb. nov. as it shares the same diagnostic features, including scape almost reaching or reaching clypeal apex, short scutellar process and straw brown apex, hemelytron attaining the abdominal apex, anterior half of the connexivum brown, and posterior half straw brown. No other specimen of P. ostenta exists besides the holotype. Breviphysoderes decora comb. nov. is removed from Physoderes and transferred to Breviphysoderes gen. nov. because it possesses the synapomorphies of the new genus (parascutellar lobes are semicircular and have prominent setigerous tubercles on the dorsal ridges of the anterior pronotal lobe).One specimen originally designated as a P.hobbyi paratype (UCR _ ENT 00018511)isconsideredtobemisidentifiedbyMillerandisheretreatedasbelongingto B. decora comb. nov. This species is known only from female specimens. Currently there are no males that can be associated with these females and hence the redescription is based on females only.Published as part of Hwang, Wei Song & Weirauch, Christiane, 2017, Uncovering hidden diversity: phylogeny and taxonomy of Physoderinae (Reduviidae, Heteroptera), with emphasis on Physoderes Westwood in the Oriental and Australasian regions, pp. 1-118 in European Journal of Taxonomy 341 on pages 17-20, DOI: 10.5852/ejt.2017.341, http://zenodo.org/record/383279
