No full textLuzonacera chang Li & Li, sp. nov. (Figs 1–2, 15) Material examined. Holotype male, Philippines, Rizal Province, Antipolo City, San Jose Village, Mystical Cave (large cave with a bird colony, 14º36.353’N, 121º12.521’E; elev. 212 m), 04 June 2015, leg. F. Ballarin & Y. Li. Paratypes. 1 male, 2 females, same data as holotype (IZCAS). Etymology. The species name is a noun in apposition derived from the Chinese pinyin "cháng" ("long") and refers to the long embolus. Diagnosis. Specimens of the two species of Luzonacera are very similar but can be distinguished as follows. The carapace in both sexes of L. chang Li & Li, sp. nov. has a medial rounded brown area (versus three longitudinal bands in both sexes of L. duan Li & Li, sp. nov.). The male of this species is easily recognized by the long spiral embolus (versus shorter in L. duan Li & Li, sp. nov.) and the relatively light constriction of the central part of the bulb (versus constriction more pronounced in L. duan Li & Li, sp. nov.). The female is diagnosed by the two pairs of curved, elongate, distally swollen spermathecae (versus curves of spermathecae relatively more twisted in L. duan Li & Li, sp. nov.). Description. Male (holotype). Total length 2.72; carapace 0.85 long, 0.92 wide; abdomen 1.70 long, 0.66 wide. Carapace round, pale yellow, with rounded brown patch medially and triangular brown patch posterior to ocular area (Fig. 2C). Fovea shallow, dark brown. Anterior margin of thoracic region distinctly elevated. Chelicerae brown with lamina, promargin with one tooth, retromargin with two small teeth, posterior surface of fang with 25 small denticles. Clypeus slanting, brown with two pale rounded areas laterally. Labium slanting, yellow. Sternum yellow, with large brown spots medially. Abdomen elongate, with complex patterns dorsally and ventrally. Legs brown; measurements: I 15.75 (4.00, 0.30, 4.10, 4.75, 2.60), II 10.97 (3.03, 0.33, 3.13, 3.40, 1.08), III 7.27 (2.13, 0.35, 2.04, 1.92, 0.83), IV 11.69 (3.44, 0.32, 3.36, 3.52, 1.05).

Luzonacera Liu & Li & Li & Zheng 2017, gen. nov.
No full text3.1 Genus Luzonacera Li & Li, gen. nov. Type species: Luzonacera chang Li & Li, sp. nov. Etymology. The genus name is a combination of “ Luzon ” (refers to Luzon, the Philippine Island) with the typical ending among genus names within this family. Gender is feminine. Diagnosis. The new genus is distinguished (together with Leclercera and Althepus) from all other genera of Ochyroceratidae by the large size, the presence of a denticle on the cheliceral promargin and the rounded maxillae. It is distinguished from Leclercera and Althepus by the absence of a retrolateral protrusion on the tibia or cymbium of the male palp and by the absence of a conductor. Description. Cheliceral promargin with lamina and one denticle, retromargin with two denticles; male with swollen palpal tibia, cymbium with distal protrusion, palp lacking retrolateral tibial or cymbial apophysis, bulb pyriform, central part remarkably constricted, spiral whip-like embolus extending subapically, conductor lacking; female with two pairs of elongate, distally swollen spermathecae. Distribution. Philippines (Rizal Province). Species composition.

Design and analysis of high performance low noise oscillators and phase lock loops
No full textThe design and implementation of high purity, high speed and power efficient clock generation Integrated Circuits continue to be one the greatest challenges facing IC designers today. In order to address this challenge, this thesis considers the modeling and design of two fundamental clock generation circuits – the VCO and PLL.An improved ring oscillator topology is proposed which has the advantage of an ultra wide tuning range. A novel noise aware ring oscillator model is also proposed which links the noise performance of the oscillator to its transistor dimensions giving insight to the design procedure. The use of this VCO model in a noise-aware PLL model allows the trade-off between noise performance and the loop bandwidth to be quantified accurately. From further analysis of the proposed PLL model, a novel PLL structure has been designed which is extremely successful at reference spur suppression.Simulation results based on the proposed model and foundry BSIM3v3 models are provided for all the VCO and PLL designs. To validate the proposed VCO topology and VCO model, two prototype chips have been fabricated and measured results show close agreement with theoretical analysis and simulatio

Body slightly convex, TBL 7.01 mm, FBL 4.21 mm; head, pronotal disc and abdomen black, elytra and most parts of legs reddish-brown. Head (Figs 9A, 9B) sub-triangular, HL 0.92 mm, HW 1.05 mm, with fine punctures, posterolateral and posterior margins with microsculpture consisting of transverse waves; eyes prominent, EyL 0.31 mm; antennae broken. Pronotum (Fig. 9C) strongly transverse, PL 1.37 mm, PW 2.59 mm, PL/PW 0.53, with fine punctures, lacking microsculpture. Elytra (Figs 9D, 9E) transverse, EL 1.74 mm, EW 2.59 mm, EL/EW 0.67, each elytron with seven complete rows of punctures. Abdominal (Fig. 9F) surface with coarse punctures, and microsculpture consisting of transverse waves; tergite VIII (Fig. 10A) with six relatively short lobes, narrowly and shallowly incised between inner lobes and outer ones; tergite IX (Fig. 10B) divided laterally to four lobes; sternite VI (Figs 10 C–E) with posterior margin narrowly and shallowly emarginate, dense and elongate pubescence arranged along emargination; sternite VII (Figs 10 F–G) with posterior margin deeply and broadly emarginate, peg setae evenly arranged along posterior margin; sternite VIII (Fig. 10H) with four lobes, shallowly incised between inner and outer lobes, mid-length 1.52 times as long as depth of incision; sternite IX elongate and asymmetric (Fig. 10I). Length of aedeagus (Figs 10 J–K) 2.04 mm, parameres short, slightly asymmetric, right paramere longer than left one in ventral view, median lobe broad at base and narrowing toward apex. Female. Unknown. Comparative notes. Olophrinus setiventris is similar to O. lantschangensis in sharing the head with fine punctures, the posterolateral and posterior margins of the head with microsculpture consisting of transverse waves, and each elytron with seven complete rows of punctures. The new species can be readily separated by the densely setose emargination of the posterior margin of male sternite VI. Distribution. China: Yunnan (Fig. 18). Etymology. The specific epithet is a noun combined from Latin ‘ seti- ’ (seta, bristle) and ‘ ventris ’ (venter), referring to the setose posterior margin of male sternite VI.Published as part of Chang, Yuan, Yin, Zi-Wei, Li, Li-Zhen & Schülke, Michael, 2019, A review of the genus Olophrinus from China (Coleoptera: Staphylinidae: Tachyporinae), pp. 307-324 in Acta Entomologica Musei Nationalis Pragae 59 (1) on page 314, DOI: 10.2478/aemnp-2019-0024, http://zenodo.org/record/448900
