Description of a new species of Forcipomyia (Euprojoannisia) Brèthes, 1914 (Diptera: Ceratopogonidae) and a key to Chinese species of the subgenus

Forcipomyia (Euprojoannisia) coronacella Han et Hou sp. n. (Diptera: Ceratopogonidae) is described and illustrated based on male specimens from China. The new species is compared with the similar congeners, F. (Euprojoannisia) palustris (Meigen, 1804) and F. (Euprojoannisia) mucronis Liu et Yu, 2001. We provide separate keys for identification of the males and females of the species of the subgenus F. (Euprojoannisia) Brèthes in China

4-(4-Nitro­benzene­sulfonamido)pyridinium bromide

In the title compound, C11H10N3O4S+·Br−, the benzene ring makes an angle of 88.4 (2)° with the pyridinium ring. The dihedral angle between the nitro group and the benzene ring is 16.5 (2)°. The ions in the crystal structure are linked by a combination of inter­molecular N—H⋯Br and non-conventional C—H⋯Br and C—H⋯O hydrogen bonds, forming a three-dimensional network

Monocular catadioptric panoramic depth estimation via improved end-to-end neural network model

In this paper, we propose a monocular catadioptric panoramic depth estimation algorithm based on an improved end-to-end neural network model. First, we use an enhanced concentric circle approximation unfolding algorithm to unfold the panoramic images captured by the catadioptric panoramic camera and then extract the effective regions. In addition, the integration of the Non-local attention mechanism is exploited to improve image understanding. Finally, a depth smoothness loss strategy is implemented to further enhance the reliability and precision of the estimated depths. Experimental results confirm that this refined algorithm is capable of providing highly accurate estimates of object depth

Systematic Evaluation of Efficacy and Safety of Acupuncture Treatment for Patients with Atrial Fibrillation

BACKGROUND: Atrial fibrillation (AF) is one of the most common types of arrhythmia diagnosed in clinical practice. Due to its negative effects on people's physical and mental health, it is necessary to prevent and treat AF. Recently, scholars have found that acupuncture can be used to treat AF, but some scholars have questioned its therapeutic efficacy. AIM: Therefore, this study was performed to assess the efficacy and safety of acupuncture treatment for AF patients. METHODS: Previously published research articles were retrieved from six databases, and the data was analysed using RevMan5.3 software with a statistically significant difference defined as P < 0.05. RESULTS: A total of 8 relevant kinds of literature were retrieved containing 633 AF patients (323 in the treatment group and 310 in the control group). Acupuncture treatment increased the total efficacy and the rate of AF cardioversion to sinus rhythm (RR: 1.38; 95% CI: 1.25 to 1.53 vs RR: 1.40;95% CI: 1.16 to 1.69; each P < 0.05), and decreased the time of AF cardioversion to sinus rhythm, the heart rate and incidence of adverse effects (RR: -3.95; 95% CI: -4.98 to -2.91 vs RR: -14.54; 95% CI: -24.09 to -5.00 vs RR: 0.48; 95% CI: 0.21 to 1.11, each P < 0.05). There was difference between retention time more and less than 30 minutes (I2 = 74.9%, P = 0.05). The funnel plot displayed a symmetrical and funnel-form shape, indicating low bias. CONCLUSION: Acupuncture has a good therapeutic effect and safety profile on patients with AF, and its application in clinical practice should be considered

Secure Network Provenance

This paper introduces secure network provenance (SNP), a novel technique that enables networked systems to explain to their operators why they are in a certain state – e.g., why a suspicious routing table entry is present on a certain router, or where a given cache entry originated. SNP provides network forensics capabilities by permitting operators to track down faulty or misbehaving nodes, and to assess the damage such nodes may have caused to the rest of the system. SNP is designed for adversarial settings and is robust to manipulation; its tamper-evident properties ensure that operators can detect when compromised nodes lie or falsely implicate correct nodes. We also present the design of SNooPy, a general-purpose SNP system. To demonstrate that SNooPy is practical, we apply it to three example applications: the Quagga BGP daemon, a declarative implementation of Chord, and Hadoop MapReduce. Our results indicate that SNooPy can efficiently explain state in an adversarial setting, that it can be applied with minimal effort, and that its costs are low enough to be practical

Ranunculus jiguanshanicus (Ranunculaceae), a new species from Sichuan, China

Ranunculus jiguanshanicus (Ranunculaceae), a new species from Chongzhou in Sichuan province, China, is here described and illustrated. The new species is easily distinguishable from other Chinese members of the genus by an array of characters, including small stature, glabrous and prostrate stems, 3-foliolate leaves with obvious petiolules (3–5 mm long), unequally 3-sected leaflets, lanceolate to linear ultimate leaflet segments, small flowers (5.2–6 mm in diameter), and long styles in the carpels and achenes (ca. 0.8 mm long). A distribution map of this new species is also provided
