Published: January 2020

In this work, the conductivity of anatase titanium dioxide (TiO2) nanowires was enhanced by lanthanum (La) and cobalt (Co) co‐doping method. The nanowires were synthesised via a facile solvothermal process. The diameter of as‐synthesised nanowires is about 300 nm and length more than 20 μm. The electrical properties were studied based on single nanowire field‐effect transistor; the anatase TiO2 nanowires exhibit n‐type conductivity with mobility of 2.18 cm2 V−1 S−1 and carrier concentration of 1.95 × 1018 cm−3. Doping of rare earth element La and transition element Co can not only reduce bandgap, but also reduce electron–hole recombination and improve carrier concentration. The distinct electrical properties of doped nanowires will open new opportunities for the application of anatase TiO2 semiconductor materials in nanoelectronics devices.

Context. Polarimetry is a very powerful tool for uncovering various properties of astronomical objects that otherwise remain hidden in standard imaging or spectroscopic observations. While common observations only measure the intensity of light, polarimetric measurements allow us to distinguish and measure the two perpendicular components of the electric field associated with the incoming light. By using polarimetry it is possible to unveil asymmetries in supernova explosions, properties of intervening dust, characteristics of atmosphere of planets, among others. However, the reliable measurement of the low polarization signal from astronomical sources requires a good control of spurious instrumental polarization induced by the various components of the optical system and the detector.
Aims. We perform a detailed multi-wavelength calibration study of the FORS2 instrument at the VLT operating in imaging polarimetric mode to characterize the spatial instrumental polarization that may affect the study of extended sources.
Methods. We used imaging polarimetry of high signal-to-noise ratio blank field BVRI observations during the full moon, when the polarization is expected to be constant across the field of view and deviations originate from the instrument, and a crowded star cluster in broad-band RI and narrow-band Hα filters, where the individual polarization values of each star across the field can be measured.
Results. We find an instrumental polarization pattern that increases radially outwards from the optical axis of the instrument reaching up to 1.4% at the edges, depending on the filter. Our results are closely approximated by an elliptical paraboloid down to less than ∼0.05% accuracy, and ∼0.02% when using non-analytic fits. We present 2D maps to correct for this spurious instrumental polarization. We also give several tips and tricks for analyzing polarimetric measurements of extended sources.
Conclusions. FORS2 is a powerful instrument that allows the linear polarimetry of extended sources to be mapped. We present and discuss a methodology that can be used to measure the polarization of such sources, and to correct for the spatial polarization induced in the optical system. This methodology could be applied to polarimetric measurements using other dual-beam polarimeters.

Abstract
Background and study aims The completeness of a polyp resection is an important determinant of quality in colonoscopy, and may reduce incidence of interval cancers. Incomplete resection rates (IRR) vary widely and range from 6.5 % to 22.7 %. Residual disease is more likely with larger polyps, for sessile serrated adenomas, and with more proximal lesions. Chromoendoscopy is increasingly employed in lesion detection. The aims of this study were to assess local IRR, and to determine whether chromoendoscopy could correctly identify residual disease post polypectomy.
Patients and methods This was a prospective study examining post polypectomy sites. Chromoendoscopy (0.13 % indigo carmine) was applied to resection bases to identify residual disease. Targeted base biopsies were taken from identified residual disease (positive group) or random base biopsies were taken when a clear base was visualised (negative group). Overall rates of incomplete resection were documented. Reported rates post chromoendoscopy and actual histological rates were documented and compared.
Results A total of 102 polyps were identified for inclusion, of which 15 % (n = 16) were excluded. Resection quality was evaluated in 86 polyps of 61 patients (female n = 33 54 %; mean Age 62.3 years). Polyps were mainly removed by cold snare (n = 71, 82.5 %). Most polyps (n = 58, 67 %) measured between 5 to 10 mm. Polyps were largely located in the right colon (n = 57, 66 %). Overall histological residual disease occurred in 17 /86 (19.6 %). Chromoendoscopy correctly identified residual disease in 13 of 17 bases (76.5 %). Only four of /86 (4.6 %) of polyp bases were missclassified post-chromoendoscopy (odds ratio 0.284 (95 % CI 0.0857–0.9409), P = 0.03).
Conclusion Indigo carmine chromoendoscopy improves early detection of residual disease post polypectomy, reducing incomplete resection rates.
Anti-B-Zell-Antikörpertherapie zur Remissionserhaltung bei Granulomatose mit Polyangiitis und mikroskopischer Polyangiitis

Published: January 2020

ZusammenfassungDie Granulomatose mit Polyangiitis (GPA) und die mikroskopische Polyangiitis (MPA) stellen als primäre nekrotisierende Kleingefäßvaskulitiden die häufigsten ANCA-assoziierten Vaskulitiden dar. Bei diesen, früher oft tödlich verlaufenden Erkrankungen kann heute durch eine Stadien-adaptierte Immunsuppression in den meisten Fällen eine Remission erzielt werden. Diese mündet jedoch nicht in eine Heilung oder medikamentenfreie Langzeitremission. Es bedarf deshalb einer remissionserhaltenden Therapie. Aktuelle randomisierte kontrollierte Studien zeigen, dass unter einer remissionserhaltenden Behandlung mit halbjährlich verabreichtem anti-B-Zell-Antikörper Rituximab weniger Rezidive auftreten als unter der bisherigen Standardmedikation mit Azathioprin bei vergleichbarem Nebenwirkungsprofil. Diese Daten führten 2018 zur Zulassung von Rituximab als remissionserhaltende Therapie der GPA und MPA. Unter einer solchen Rituximab-Therapie muss mit einer Immunglobulindepletion sowie späten Zytopenien mit begleitenden Infekten gerechnet werden. Leitlinien und Expertenempfehlungen zu Infektprophylaxen, Impfungen und Immunglobulinsubstitution werden in diesem Beitrag vorgestellt.
Measuring Subjective Ideological Disagreement with the US Supreme Court
Authors: Nelson Michael J. , Gibson James L. 
Published: January 2020

AbstractConventional wisdom suggests that judicial legitimacy should be relatively unaffected by satisfaction with the ideological direction of judicial policy making. Recent studies challenge this assertion. The key to resolving this conundrum is estimating individual-level satisfaction with the ideological direction of judicial policy making reliably and validly. We examine the accuracy of several common measures of the concept. We find that 40% of the respondents repudiate their own scores on these measures. With this much systematic measurement error in such an important independent variable, the question of whether the Supreme Court’s institutional legitimacy is conditional on ideological agreement with its decisions must be reexamined.
Triangular color codes on trivalent graphs with flag qubits
Authors: Chamberland Christopher , Kubica Aleksander , Yoder Theodore J , Zhu Guanyu 
Published: January 2020

Abstract
The color code is a topological quantum error-correcting code supporting a variety of valuable fault-tolerant logical gates. Its two-dimensional version, the triangular color code, may soon be realized with currently available superconducting hardware despite constrained qubit connectivity. To guide this experimental effort, we study the storage threshold of the triangular color code against circuit-level depolarizing noise. First, we adapt the Restriction Decoder to the setting of the triangular color code and to phenomenological noise. Then, we propose a fault-tolerant implementation of the stabilizer measurement circuits, which incorporates flag qubits. We show how information from flag qubits can be used in an efficient and scalable way with the Restriction Decoder to maintain the effective distance of the code. We numerically estimate the threshold of the triangular color code to be 0.2%, which is competitive with the thresholds of other topological quantum codes. We also prove that 1-flag stabilizer measurement circuits are sufficient to preserve the full code distance, which may be used to find simpler syndrome extraction circuits of the color code.
About the Danger of Vibration Combustion in Gas Explosions in the Room
Authors: Polandov Iu H , Korolchenko A D 
Published: January 2020

Abstract
In recent years, in experimental gas explosions in open volumes, such a phenomenon as vibration combustion has been recorded or, as they sometimes say, flame-acoustic combustion, or simply combustion, but accompanied by acoustic gas oscillations. Generally speaking, this type of combustion was known for a long time in the 19th century, from the time of Higgins and Rijke, and acquired the poetic name “singing flame”. However, at the onset of gas turbine and rocket engines, this phenomenon manifested itself in their combustion chambers and was designated as a whip, as it resulted in structural damage. But the vibration combustion is known not only for the destructive force, but also for the intensification of fuel combustion process in high-duty furnaces.

Space-based quantification of per capita CO2 emissions from cities
Authors: Wu Dien , Lin John C , Oda Tomohiro , Kort Eric A 
Published: January 2020

Abstract
Urban areas are currently responsible for ∼70% of the global energy-related carbon dioxide (CO2) emissions, and rapid ongoing global urbanization is increasing the number and size of cities. Thus, understanding city-scale CO2 emissions and how they vary between cities with different urban densities is a critical task. While the relationship between CO2 emissions and population density has been explored widely in prior studies, their conclusions were sensitive to inconsistent definitions of urban boundaries and the reliance upon CO2 emission inventories that implicitly assumed population relationships. Here we provide the first independent estimates of direct per capita CO2 emissions (E
pc) from spaceborne atmospheric CO2 measurements from the Orbiting Carbon Observatory-2 (OCO-2) for a total 20 cities across multiple continents. The analysis accounts for the influence of meteorology on the satellite observations with an atmospheric model. The resultant upwind source region sampled by the satellite serves as an objective urban extent for aggregating emissions and population densities. Thus, we are able to detect emission ‘hotspots’ on a per capita basis from a few cities, subject to sampling restrictions from OCO-2. Our results suggest that E
pc declines as population densities increase, albeit the decrease in E
pc is partially limited by the positive correlation between E
pc and per capita gross domestic product. As additional CO2-observing satellites are launched in the coming years, our space-based approach to understanding CO2 emissions from cities has significant potential in tracking and evaluating the future trajectory of urban growth and informing the effects of carbon reduction plans.

Abstract
Aceh’s patchouli is one of the superior local commodities, and its growth and yield could be improved in various means. One way to increase the patchouli production can be done by using bio-fertilizer mycorrhizal local strain. The purpose of this research was to study effect of bio-fertilizer mycorrhizal local specific strain on the growth and yield of patchouli in Entisols. We conducted two experiment. The first experiment was the propagation technique of mycorrhizae on Entisols soil and the second experiment the test of the fertilizer on a greenhouse pot scale for the growth of patchouli seedlings. The research was arranged by a non-factorial randomized block design with three replications. The investigated factor was the bio-fertilizer mycorrhizal from local specific strain with four levels, i.e. M0 (without mycorrhizae), M1 (Glomus mosseae) M2 (Gigaspora sp) and M3 (Mixing between Glomus mosseae and Gigaspora sp). The variety of patchouli used in this study was the Tapak Tuan variety. The observed parameters were seedling height and seedling diameter of patchouli at 45, 60 days after planting; additionally the parameter of patchouli yields consist of number of leaves, number of branches and weight of leaves were observed at 90 days after planting, and root colonization by mycorrhizae. The results showed that mixed mycorrhizal strains between Glomus mosseae + Gigaspora sp contributed to the best marks for increasing growth and yield of seedling patchouli in Entisolss. The similar trend result was also found in the root colonization by mycorrhizae. The strain of mycorrhizal of Gigaspora sp application was not effective for increasing the growth and yield of Aceh’s patchouli in Entisols.
