Head: Face dense gray pollinose; narrowed to width of 1 ommatidium or less just above midpoint, wider above and below. Vertex blue-green, to brownish-green, with some magenta reflections; with moderately dense gray pollen. Ocellar setae long, subequal in length to dc setae. Outer vertical setae twothirds length of ocellars. Palpus yellow-brown, somewhat elongate, rounded apically; with long, slender, yellow-brown setae. Scape cylindrical, slightly longer than first flagellomere; mostly yellow, often partly brownish. Pedicel mostly yellow, often slightly brown. First flagellomere (Fig. 2) short triangular, a little longer than wide; somewhat rounded apically. Thorax: Mesonotum dark brown, with green/blue reflections; with moderately dense gray to brownish-gray pollen. Pleura blue-green with sparse gray pollen. Metepisternum and metepimeron largely yellow.

Left hypandrial arm large, hooked; right hypandrial arm short (Figs. 6–8).</p> <p> <b>Description. Males:</b> <i>Head:</i> without lower postcranial hairs (beard) or gena. Face short, not reaching ventral margin of eyes; very narrow to obliterated near middle by encroaching eyes. Postocular setae white, with dorsal 5–7 usually yellow-brown to brown, becoming slightly longer and more slender ventrally. Ocellar and outer vertical setae long. Scape and pedicel mostly yellow; first flagellomere triangular, brown. Arista basal, hispid; with somewhat thickened basal aristomere. <i>Thorax</i>: 6 long dc; ac in a single row. Postpronotal hairs present (Fig. 2; see Diagnosis of genus). Scutellum with one pair of long setae, without hairs. Proepimeron bare. Notopleuron with 2 long setae. Halter yellow. Calypter yellow, black at apex; with fan of long yellow setae. <i>Legs:</i> including coxa, long and slender, yellow, with distal tarsomeres often brownish. Anterior surface of coxa I with white hairs and yellow-brown to brown setae at apex. Coxa II and III with long, slender, dorsal seta near 1/2. Tibia I without distinct setae. Femur II and III with preapical anterior seta; with <i>av</i> seta near apex. <i>Wing:</i> male wings variously modified, but all with slender, very short to long marginal hairs near apex (Figs. 1, 3–5). <i>Abdomen:</i> cylindrical; dark brown, with some yellow near base. T1 with very long, slender setae along posterior edge, lateral setae longest and often yellowish, medial setae shorter and darker. Hypopygium (Figs. 6–8) small, mostly embedded; epandrium longer than wide, without distinct lobes. Surstylus with ventral lobe larger than dorsal lobe; dorsal lobe narrow, digitiform, with one lateral seta before apex; ventral lobe much broader, with 3–4 apical setae and subapical digitiform lobe bearing one seta at apex. Postgonites present as a pair of tubular sclerites, extending around base of phallus and looping ventrally then dorsally to weakly fuse with ventral surface of a small sclerite ventroapical of sperm pump, and branching laterally to fuse with base of bacilliform sclerites. Cerci short, narrow, pale brown with yellow setae and hairs, with 2–3 very long pale yellow setae at apex. Hypandrium (Fig. 6) asymmetrical, arrowhead-shaped ventrally, extending dorsally near base on each side, then arising as hooked arms extending apically which fuse basally with bacilliform sclerites; right apical hypandrial arm short; left hypandrial arm very large, hooked to the left, with microtrichia covering apex.</p> <p> <b>Females:</b> Similar in appearance to <i>Sympycnus</i> and <i>Calyxochaetus</i>; can be recognized by postpronotal hairs. Similar to males but: face broader, only slightly narrowed below (width subequal to width of first flagellomere); palpus broader; first flagellomere short triangular, a little wider than long; scape and pedicel often with some brown dorsally; wings unmodified.</p> <p> <b>Remarks:</b> <i>Erebomyia</i> belongs to the subfamily Sympycninae, a diverse cosmopolitan taxon containing many genera and species. Although its position within the subfamily is unclear, <i>Erebomyia</i> appears to be monophyletic based on the presence of postpronotal hairs (Fig. 2), development of the left hypandrial arm into a large hook, modified wings in males, and perhaps habitat specialization - occurring only on deeply shaded vertical or overhanging, bare rock. The paucity of specimens in collections (we have searched most of the major collections in North America) is surprising given their occurrence, often in large numbers, in wellcollected areas, e.g., Madera Canyon and Cave Creek Canyon in Arizona. Increased attention to the microhabitats in which <i>Erebomyia</i> occur (dark rock cavities near streams) particularly in southwestern U.S.A. and Sonora Mexico, should provide additional species.</p> <p> Postpronotal hairs, though sometimes difficult to see, appear to be a synapomorphy separating <i>Erebomyia</i> from other Nearctic Sympycninae and perhaps other Dolichopodidae in general. They are a cluster of very short, pale hairs found on the extreme anterior slope of the scutum in line with the dc setae (Fig 2).</p> <p> Males are easily identified to species using wing characters. Determination of females is difficult since, unfortunately, the distinct wing modifications of males are not reflected in females. Females of <i>E. ramseyensis</i> can be distinguished by the relatively short anterior preapical seta on femur III. Subtle differences appear to exist among the other species as noted in descriptions, but we cannot find reliable diagnostic features to allow confident identification of isolated females.</p>Published as part of <i>Hurley, Richard L. & Runyon, Justin B., 2009, A review of Erebomyia (Diptera: Dolichopodidae), with descriptions of three new species, pp. 38-48 in Zootaxa 2054</i> on pages 39-41, DOI: <a href="http://zenodo.org/record/274772">10.5281/zenodo.274772</a>

Screening for diabetes mellitus in patients with hidradenitis suppurativa
No full textHidradenitis suppurativa (HS) is a chronic skin disease that is often associated with metabolic disorders. Diabetes mellitus (DM) is a frequent comorbidity in HS. There is currently no established screening for DM in HS patients. The aim of our study was to identify high-risk groups of HS patients that develop DM and to assess the frequency of different types of DM present in HS patients. To do so, we conducted a monocentric study in 99 patients with HS. All patients underwent detailed clinical and laboratory assessments, including the determination of glycated hemoglobin. Among the 20.2% of patients that presented with DM, type 2 was by far the most prevalent (19 out of 20 patients). Moreover, male gender, age, BMI, Hurley stage, modified Hidradenitis Suppurativa Score (mHSS), DLQI and hypertension all correlated with the glycated hemoglobin levels in the HS patients. In the multivariable analysis, Hurley stage III, older age, and higher BMI were significantly associated with DM. Specifically, patients at Hurley stage III were at a 5.3-fold increased risk of having DM type II compared to patients at earlier Hurley stages. Since many of the HS patients had not been diagnosed, our study reveals shortcomings in the screening for DM and suggest that this should be routinely performed in HS patients at high risk to avoid secondary complications

Entanglement and quantity in quantum space - About quantum measurement (II)
No full textAs a continuation and extension of "quantity in phase space" "quantity in quantum space" is introduced. With that, the disappearing of quantum interference discussed in a previous paper [S. Durr, et al., Nature 395 (1998) 33] is explained in the same spirit as our recent papers [Ren De-Ming, Commun.

Sneutrino DM in the NMSSM with inverse seesaw mechanism
No full textIn supersymmetric theories like the Next-to-Minimal Supersymmetric Standard Model (NMSSM), the lightest neutralino with bino or singlino as its dominant component is customarily taken as dark matter (DM) candidate. Since light Higgsinos favored by naturalness can strength the couplings of the DM and thus enhance the DM-nucleon scattering rate, the tension between naturalness and DM direct detection results becomes more and more acute with the improved experimental sensitivity. In this work, we extend the NMSSM by inverse seesaw mechanism to generate neutrino mass, and show that in certain parameter space the lightest sneutrino may act as a viable DM candidate, i.e. it can annihilate by multi-channels to get correct relic density and meanwhile satisfy all experimental constraints. The most striking feature of the extension is that the DM-nucleon scattering rate can be naturally below its current experimental bounds regardless of the higgsino mass, and hence it alleviates the tension between naturalness and DM experiments. Other interesting features include that the Higgs phenomenology becomes much richer than that of the original NMSSM due to the relaxed constraints from DM physics and also due to the presence of extra neutrinos, and that the signatures of sparticles at colliders are quite different from those with neutralino as DM candidate.National Natural Science Foundation of China (NNSFC) [11575053]SCI(E)ARTICLE1

Policy-driven Data Sharing over Attribute-Based Encryption supporting Dual Membership
No full textAttribute-Based Encryption (ABE) plays an important role in current secure data sharing through fine-grained customizable policies. However, the existing ABE schemes only support simple predicates, = and ≠, but cannot express a more general membership predicates, ∈ and ∉, in policies. The low expressivity of ABE will enlarge the ciphertext storage and reduce the communication efficiency. To overcome this problem, we propose an ABE supporting Dual Membership (DM-ABE). The core problem for implementing this scheme is how to use cryptographic methods to decide the membership between the verified element and the given set. In order to solve this problem, we design a cryptographic algorithm, called Secure Decision of Membership (SDM), based on aggregation functions. In this algorithm, any set can be aggregated into one cryptographic element, and the verified element and the given set can be converted into another cryptographic element in decision process. The membership between them can be decided by the above two cryptographic elements. Furthermore, we construct the DM-ABE by using SDM. Because of the good expressivity of our DM-ABE, we further propose a novel cryptographic data sharing framework by integrating DM-ABE and attribute-based access control to provide fine-grained access control and security protection for private data. In the security proof of DM-ABE, we prove that the DM-ABE satisfies the semantic security against chosen-plaintext attacks under the DBDHE assumption in the standard model through a unified way, considering both two encryption methods for ∈ and ∉ at the same time. Finally, we analyze our scheme in terms of time and space complexity, and compare it with some existing schemes. The results show that our DM-ABE has a better expressive ability on the boolean logic of general membership predicates, ∈ and ∉.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Cyber Securit
