Quantum interference approach to two-photon correlation phenomena of chaotic light
No full textTwo-photon correlation phenomena of chaotic light, including the historical Hanbury Brown and Twiss effect, are essentially quantum effect of two-photon interference, instead of classical statistical correlation between intensity fluctuations. To support our view, we analyze a "ghost" imaging experiment with chaotic light for which the classical understanding does not give a satisfactory interpretation. We also provide a two-photon optical picture of ghost imaging with chaotic light in terms of two-photon phase-conjugate mirror which suggests lensless imaging applications for radiations for which no effective lens is available

Obstrucción esofágica por cuerpo extraño en Shih Tzu
No full textUn canino hembra, Shih Tzu de 7 años, ingresó a la clínica veterinaria UDCA, con reporte
de haber ingerido un hueso y episodios de vómito e inapetencia. Al examen clínico se
evidenció taquicardia, baja condición corporal, regurgitación, tos seca y reflejo tusígeno
positivo. Se realizaron exámenes de laboratorio y estudio radiológico de tórax, los cuales
evidenciaron presencia de cuerpo extraño radiopaco a nivel del esófago caudal. Se decidió
realizar manejo terapéutico y tratamiento quirúrgico con una esofagotomía por medio de una toracotomía lateral caudal para la extracción del cuerpo extraño. Se encontró estable en el posquirúrgico inmediato, pero posteriormente presentó neumotórax, pleuritis y se observó dehiscencia de la herida quirúrgica intercostal, por lo que, se decidió reintervenir
quirúrgicamente, sin embargo, la paciente falleció.A 7 years old female Shih Tzu, was admitted to the UDCA veterinary clinic, with a report of
having ingested a bone, vomit episodes and loss of appetite. The clinical examination
revealed tachycardia, low body condition, regurgitation, dry cough, and positive cough
reflex. She underwent laboratory tests and a chest radiological study, which revealed the
presence of a radiopaque foreign body at the level of the caudal esophagus. It was decided to
perform therapeutic management and surgical treatment with a caudal esophagotomy through a lateral thoracotomy to extract the foreign body. She was stable postoperatively, but later she presented pneumothorax, pleurisy, and dehiscence of the intercostal surgical wound was observed, so it was decided to perform a surgical revision, however, the patient died.Incluye bibliografíaPregradoMédico(a) Veterinario ZootecnistaMedicina Veterinaria y Zootecni

Comparative material. Geothelphusa monticola Shy, Ng & Yu, 1994: 1 holotype male (NTOU F10204), Siaoyako (= Sheauyeakow), Heping (= Hoping), Taichung City, Taiwan, coll. J.-Y. Shy & W.-L. Tsay, 6 Jun. 1992; Geothelphusa takuan Shy, Ng & Yu, 1994: 1 holotype male (NTOU F10205), Daguan (= Takuan), Fusing (= Fuhsing), Taoyuan County, Taiwan, coll. J.-Y. Shy & W.-L. Tsay, 1 Nov. 1992. Description. Carapace (Fig. 2A–B) swollen longitudinally, transversely; dorsal surface smooth, glabrous, with fine pits. Carapace length, width 1.7, 2.2 carapace height, respectively. Frontal margin slightly dived into 2 lobes, without tooth. Postorbital cristae distinct, supraorbital margin smooth, without granules; infraorbital margin smooth to almost smooth, lined with inconspicuous granules. External orbital angle stout, external orbital region concave. Anterolateral margin distinct, lined with inconspicuous granules, without epibranchial tooth. Postorbital crista faint, smooth. Gastric, cardiac, intestinal regions smooth. H-shaped groove distinct. Tip of medium lobe of epistome stout. Distance between tip of closed male abdomen, anterior margin of thoracic sternite 3 about 1.1 length of thoracic sternites 1, 2 (Fig. 2C). Chelipeds of adult males unequal, fingers of larger chela forming obliquely triangular gape when closed. Ambulatory legs smooth, dorsal, ventral margins of dactyli with 2 rows of small spines, respectively. Second leg about 1.8 carapace length. Telson of male abdomen bell-shaped, moderately short, width about 1.4 length (Fig. 2C). Subterminal segment of G1 (Fig. 1A–C) curving inwards, outer proximal margin with small tubercle, inner proximal margin clearly dilated; terminal segment slightly curving inwards to almost straight (length /width = 2.4); total length of G1 5.5 terminal segment; length of synovial membrane about 3.3 maximum width. Outer proximal margin of basal segment of G2 (Fig. 1D) dilated, showing a single lobe; distal segment short, about 0.12 total length. Etymology. The species is named for the type locality, the Cilan Forest, in northern Taiwan. The name is used as a noun in apposition. Coloration. Carapace and ambulatory legs grayish brown, mottled with dark brown spots; chelae orange-red, with dark brown spots; tip and inner edge of fingers white (Fig. 2D–G). Ecological notes. The specimens were collected from the headstream of Danshuei River (Fig. 2H) near the boundary of Hsinchu and Yilan counties, near Yuanyang Lake Nature Reserve, with an altitude about 2000 m. The mean monthly water temperatures were 10.3–14.6°C during April to December, 2012 (mean 12.6°C) for the adjacent Yuanyang Lake, with the same drainage. Remarks. Geothelphusa cilan sp. nov. is similar to G. monticola and G. takuan both of which are present in the adjacent regions. The subterminal segment of the G1 of G. monticola is slightly S-shaped, and those of G. takuan and G. cilan sp. nov. are slightly curved inwards, but G. monticola and G. takuan have a conspicuous tubercle and G. cilan sp. nov. a small tubercle at the outer proximal margin. The terminal segment of the G1 of G. monticola is slender (length/width = 3.3), and those of G. takuan and G. cilan sp. nov. are stouter (length/width = 1.8 and 2.4, respectively). Geothelphusa takuan and G. cilan sp. nov. have shorter distance between the tip of the closed male abdomen and anterior margin of thoracic sternite 3 (ratio = 1.0 and 1.1, respectively) than that in G. monticola (ratio = 1.6). DNA analyses and discussion. A 616-658 basepair (bp) segment of the COI was amplified from 9 specimens of G. cilan and 10 specimens of the closely related G. monticola, resulting in 5 different haplotypes (Table 1). The studied segment was AT rich (63.2%) (T, 35.4%; A, 27.8%; G, 16.5%; and C, 20.3%). In this gene, 18 positions were variable and 13 parsimoniously informative. The phylogenetic tree constructed by BI and ML methods (Fig. 3) supports the clade of G. cilan sp. nov., which is a sister species to another montane clade, G. monticola. The pairwise nucleotide divergences for COI with K2P distance is shown in Table 2. The mean interspecific K2P distance of G. cilan is 2.26% with G. monticola, which is 38 or 17 times greater than the mean intraspecific distance of G. cilan (0.06%) or G. monticola (0.13%), respectively (Table 2). The lowest interspecific K2P distance of G. cilan is 2.15% with G. monticola, which is 13 or 4.7 times greater than the largest intraspecific distance of G. cilan (0.16%) or G. monticola (0.46%). The interspecific K2P distance of 2.15% – 2.65% between G.cilan sp. nov. and G. monticola is not high, but still higher than the distance between G. marginata Naruse, Shokita & Shy, 2004 and G. fulva Naruse, Shokita & Shy, 2004 (1.48%–1.99%, Shih et al. 2011); and the distance among G. makatao Shih & Shy, 2009, G. shernshan Chen, Cheng & Shy, 2005, and G. pingtung Tan & Liu, 1998 (1.65%–1.98%, recalculated from Shih & Shy 2009). Although the nearest distance between the localities of G. cilan sp. nov. and G. monticola (see nos. 32 and 27 in fig. 1 of Shih et al. 2011) is only about 13 km, both areas belong to different drainages, the Danshuei and Daja rivers, respectively. Furthermore, several mountains more than 2000 m a.s.l. separated the two areas. Based on the substitution rates of 2.33% per 10 6 yr for COI of terrestrial crabs (see Schubart et al. 1998), the two sister species diverged at 1.0±0.2 million years ago (mya) (with uncorrected p-distance divergences of 2.35%±0.56%), which is quite young allopatric speciation, considering the geological history of Taiwan is about 5 mya (see Shih et al. 2006).Published as part of Shy, Jhy-Yun, Shih, Hsi-Te & Mao, Jean-Jay, 2014, Description of a new montane freshwater crab (Crustacea: Potamidae: Geothelphusa) from northern Taiwan, pp. 565-572 in Zootaxa 3869 (5) on pages 567-568, DOI: 10.11646/zootaxa.3869.5.6, http://zenodo.org/record/494740
