Localization effect on Rényi complexity of Kratzer potential in the presence of Aharonov‐Bohm field
Authors: Ghosh Piu , Nath Debraj 
Published: September 2020

AbstractExact wave functions are obtained for noncentral Kratzer potential in the presence of Aharonov‐Bohm flux field in terms of associate Laguerre and Jacobi polynomials. The exact form of Rényi entropy and generalized Rényi complexity are determined for positive integral order and , respectively. The narrowest confined and widest spread radial wave functions dominate the localization property of rotational wave functions for the optimum measure of Rényi entropy. The minimum and the maximum values of the Rényi entropy are found for the narrowest confined and widest spread radial wave functions, respectively. Conversely, the narrowest confined and widest spread rotational wave functions dominate the localization property of radial wave functions for the optimum measure of the generalized Rényi and shape Rényi complexities. If the generalized Rényi and shape Rényi complexities are minimum for the narrowest confined rotational wave function, then they will be maximum for the widest spread rotational wave function and vice versa.
Power sector analysis of the BBIN sub‐region with a spatially disaggregated dynamic power generation mix model

Published: September 2020

This study evaluates the optimal expansion of the electricity sector of the BBIN (Bangladesh, Bhutan, India, and Nepal) sub‐region with a detailed analysis of unevenly distributed resources and electricity demand, by developing a multi‐regional dynamic power sector optimization model, characterized by 27 nodes, 45 fuel transport lines, and 63 transmission lines in hourly temporal resolution. Scenarios developed in this paper assess the impact of 2 °C Paris agreement on production, transportation, and consumption of indigenous resources like coal and gas, the share of renewables and nuclear in the power generation mix, the utilization of huge untapped hydro resources through an expansion of cross‐border transmission lines. The simulation results show that hydro, wind, nuclear, and PV will be the dominant power sources, thus reducing the current share of coal, under carbon regulation scenario. The requirements of PV exceed its estimated commercially exploitable potential in most of the nodes in the nuclear‐restricted scenario. Expanding cross‐border transmission capacity will be an effective way to exploit untapped hydro resources so that Bangladesh and India can import power from Bhutan and Nepal. Although there is a slight increase in coal demand in the future, capacity expansion of fuel networks is not economical under adopted emission levels. © 2020 Institute of Electrical Engineers of Japan.

Constraining the gauge and scalar sectors of the doublet left-right symmetric model
Authors: Bernard Véronique , Descotes-Genon Sébastien , Silva Luiz Vale 
Published: September 2020

Abstract
We consider a left-right symmetric extension of the Standard Model where the spontaneous breakdown of the left-right symmetry is triggered by doublets. The electroweak ρ parameter is protected from large corrections in this Doublet Left-Right Model (DLRM), contrary to the triplet case. This allows in principle for more diverse patterns of symmetry breaking. We consider several constraints on the gauge and scalar sectors of DLRM: the unitarity of scattering processes involving gauge bosons with longitudinal polarisations, the radiative corrections to the muon ∆r parameter and the electroweak precision observables measured at the Z pole and at low energies. Combining these constraints within the frequentist CKMfitter approach, we see that the fit pushes the scale of left-right symmetry breaking up to a few TeV, while favouring an electroweak symmetry breaking triggered not only by the SU(2)L×SU(2)R bi-doublet, which is the case most commonly considered in the literature, but also by the SU(2)L doublet.
Classification of topological phases with finite internal symmetries in all dimensions

Published: September 2020

Abstract
We develop a mathematical theory of symmetry protected trivial (SPT) orders and anomaly-free symmetry enriched topological (SET) orders in all dimensions via two different approaches with an emphasis on the second approach. The first approach is to gauge the symmetry in the same dimension by adding topological excitations as it was done in the 2d case, in which the gauging process is mathematically described by the minimal modular extensions of unitary braided fusion 1-categories. This 2d result immediately generalizes to all dimensions except in 1d, which is treated with special care. The second approach is to use the 1-dimensional higher bulk of the SPT/SET order and the boundary-bulk relation. This approach also leads us to a precise mathematical description and a classification of SPT/SET orders in all dimensions. The equivalence of these two approaches, together with known physical results, provides us with many precise mathematical predictions.

Stellenwert der operativen Behandlung thorakolumbaler Wirbelkörperfrakturen für die Überlebenswahrscheinlichkeit alterstraumatologischer Patienten
Authors: Wiedl Andreas , Förch Stefan , Fenwick Annabel , Mayr Edgar 
Published: September 2020

Zusammenfassung
Hintergrund
Osteoporotische Wirbelkörperfrakturen sind eine häufige Verletzung alter Menschen, deren optimale Behandlung (konservativ oder operativ) diskutiert wird.
Die Literatur beschreibt nach Wirbelkörperaugmentationen geringere Mortalitäten als nach konservativer Therapie. Ob eine positive Korrelation des operativen Vorgehens mit dem Überleben nach oben genannten Verletzungen besteht, soll im eigenen alterstraumatologischen Patientenkollektiv überprüft werden.

Methodik
Es erfolgte die Erfassung aller Patienten, die mit einer osteoporotischen Wirbelkörperfraktur vom 01.02.2014 bis 31.01.2015 auf einer alterstraumatologischen Station behandelt wurden. Im Rahmen eines 2‑Jahres-Follow-up wurden diese auf die assoziierte Sterblichkeit untersucht, wobei insbesondere der Einfluss der Therapie untersucht wurde.

Ergebnisse
Insgesamt konnten 74 Patienten (Rücklauf 74 %) mit einem durchschnittlichen Alter von 83,2 Jahren eingeschlossen werden, davon wurden 40 konservativ und 34 operativ versorgt. Die gesamte Ein- und Zweijahresmortalität betrugen 29,7 % bzw. 35,1 %, nach operativer Versorgung 20,6 % bzw. 23,5 % und nach konservativer Therapie 37,5 % bzw. 45 % (p = 0,113 bzw. 0,086, Chi-Quadrat-Test). Die um Störfaktoren bereinigte „hazard ratio“ betrug 2,0 (95 %-KI: 0,686–6,100)

Diskussion
Auch wenn möglicherweise wegen der eher geringen Fallzahl kein signifikantes Ergebnis nachgewiesen werden konnte, zeigen die Analysen eine Tendenz des verbesserten Überlebens nach operativem Vorgehen. Dies steht im Einklang mit internationalen Studien. Bestehende Untersuchungen lassen vermuten, dass die Reduktion der Kyphosierung durch die Operation einen wichtigen kausalen Zusammenhang darstellen könnte.

Published: September 2020

Abstract
Purpose
New guidelines recommend thrombectomy up to 24 h in selected patients; however, the workload and benefit of extending time window are not known. We conducted a prospective single-centre study to determine the caseload, imaging and interventional need of extended time window.

Methods
All consecutive ischemic stroke patients within 24 h from onset in an 11-month period were included. Thrombectomy eligibility in the 0–6 h time window was based on current guidelines; in the 6–24 h time window, it was based on a combination of DEFUSE 3 and DAWN study criteria using MRI to identify target mismatch. Clinical outcome in treated patients was assessed at 3 months.

Results
Within 24 h of onset, 437 patients were admitted. In the 0–6 h time window, 238 patients (54.5%) arrived of whom 221 (92.9%) underwent CTA or MRA, 82 (34.5%) had large vessel occlusion (LVO), 30 (12.6%) had thrombectomy and 11 (36.6%) became independent (mRS ≤ 2). In the extended 6–24 h time window, 199 patients (45.5%) arrived of whom 127 (63.8%) underwent CTA or MRA, 44 (22.1%) had LVO, 8 (4%) had thrombectomy and 4 (50%) became independent.

Conclusion
Extending the time window from 6 to 24 h results in a 26.7% increase in patients receiving thrombectomy and a 36.4% increase of independent clinical outcome in treated patients at the price of a significantly increased burden of clinical and imaging screening due to the similar caseload but a smaller proportion of treatment eligible patients in the extended as compared with the standard time window.
Zinc distribution within breast cancer tissue of different intrinsic subtypes
Authors: Rusch Peter , Hirner Alfred V. , Schmitz Oliver , Kimmig Rainer , Hoffmann Oliver , Diel Maxim 
Published: September 2020

Abstract
Purpose
To show feasibility of laser ablation inductively coupled mass spectrometry (LA-ICPMS) for analysis of zinc content and concentration in breast cancer tissue and to correlate this with validated prognostic and predictive markers, i.e. histological grading and expression of steroid receptors (estrogen receptor, ER; progesterone receptor, PR) and human epidermal growth-factor receptor 2 (Her2).

Methods
28 samples of human invasive ductal breast cancer tissue were subclassified into groups of four different intrinsic subtypes according to the expression of ER, PR and Her2 by immunohistological staining and then analyzed for zinc content and distribution by LA-ICPMS applying a calibration technique based on spiked polyacrylamide gels. A correlation of zinc concentration with histological grading and molecular subtypes was analyzed.

Results
Consistent with results of a pilot-study LA-ICPMS was feasible to show zinc accumulation in cancerous tissue, even more adjacent healthy stroma was with proportional increase of zinc. Zinc levels were most elevated in triple-positive (TPBC) and in triple-negative (TNB) breast cancers.

Conclusion
LA-ICPMS was feasible to confirm a connection between zinc and grade of malignancy; furthermore, focusing on a correlation of zinc and intrinsic breast cancer subtypes, LA-ICPMS depicted an upwards trend of zinc for “high-risk-cancers” with highest levels in Her2-positive and in triple-negative (TNBC) disease. The currently uncommon alliance of clinicians and analytical chemists in basic research is most promising to exploit the full potential of diagnostic accuracy in the efforts to solve the enigma of breast cancer initiation and course of disease.
Virtual reality experiences promote autobiographical retrieval mechanisms: Electrophysiological correlates of laboratory and virtual experiences
Authors: Kisker Joanna , Gruber Thomas , Schöne Benjamin 
Published: September 2020

AbstractRecent advancements in memory research indicate that virtual reality (VR) experiences are more vividly memorized as compared to conventional laboratory events. In contrast to the latter, VR experiences are highly immersive, simulating the multimodality, vividness and inclusiveness of real-life experiences. Therefore, VR might enable researchers to identify memory processes underlying events which participants have actually experienced, in contrast to conventional on-screen experiences. To differentiate the electrophysiological correlates of memory processes underlying VR experiences as compared to conventional laboratory experiences, participants watched videos either in a PC condition or in a VR condition, followed by an unannounced recognition memory test. As hypothesized, we replicated the well-established theta old/new effect for the PC condition, but remarkably, this effect was absent in the VR condition. Additionally, the latter was accompanied by significantly lower alpha activity as compared to the PC condition. As increases in theta-band responses are related to top-down control on, and memory load during retrieval, the observed theta responses might rather relate to retrieval effort than to retrieval success per se. Congruently, higher alpha activity measured over occipital sensor areas in the PC condition reflect visually guided search processes within episodic memory. The VR condition comes in with lower alpha activity, reflecting immediate and effortless memory access. Hence, our findings indicate that the retrieval of VR experiences promotes autobiographical retrieval mechanisms, whereas recalling conventional laboratory events comes in with higher effort, which might not reflect the mechanisms of everyday memory.

Abstract
Background and objective
The main challenge of bypass surgery of complex MCA aneurysms is not the selection of the bypass type but the initial decision-making of how to exclude the affected vessel segment from circulation. To this end, we have previously proposed a classification for complex MCA aneurysms based on the preoperative angiography. The current study aimed to validate this new classification and assess its diagnostic reliability using the giant aneurysm registry as an independent data set.

Methods
We reviewed the pretreatment neuroimaging of 51 patients with giant (> 2.5 cm) MCA aneurysms from 18 centers, prospectively entered into the international giant aneurysm registry. We classified the aneurysms according to our previously proposed Berlin classification for complex MCA aneurysms. To test for interrater diagnostic reliability, the data set was reviewed by four independent observers.

Results
We were able to classify all 51 aneurysms according to the Berlin classification for complex MCA aneurysms. Eight percent of the aneurysm were classified as type 1a, 14% as type 1b, 14% as type 2a, 24% as type 2b, 33% as type 2c, and 8% as type 3. The interrater reliability was moderate with Fleiss’s Kappa of 0.419.

Conclusion
The recently published Berlin classification for complex MCA aneurysms showed diagnostic reliability, independent of the observer when applied to the MCA aneurysms of the international giant aneurysm registry.

Published: September 2020

AbstractThe production of soybean continues to increase worldwide. People are showing more interest in the beneficial health effects of soybeans than before. However, the origin and history of soybeans are still being discussed among many researchers. Chromatographic methods enable the desirable separation of a variety of isoflavones from soybeans. The structures of isolated soy isoflavones have been successfully identified in tandem with spectroscopic analytical instruments and technologies such as liquid chromatography, mass spectrometry, and nuclear magnetic resonance spectroscopy. The theoretical background behind spectroscopy may help improve the understanding for the analysis of isoflavones in soybeans and soy-derived foods. This review covers the origin of the English name of soybean and its scientific name, Glycine max (L.) Merrill, based on the evidence reported to date. Moreover, the reports of soy isoflavones discovered over a period of about 100 years have been briefly reviewed.
What Role Can Trained Volunteers Add to Chronic Disease Care of Immigrants?
Authors: Rosenberg Ellen , Carver Tamara , Mamishi Nina , Bartlett Gillian 
Published: September 2020

AbstractTo help primary care teams improve patient-centered care, we elicited health and life goals of immigrants with a chronic disease. We conducted an exploratory study of the (1) acceptability of home visits by volunteers to collect health information and (2) content of health and life goals within a primary care program for immigrants with chronic disease. Pairs of trained community volunteers visited 23 patients in their homes and asked them to identify three life goals and three health goals. We conducted content analyses of written notes. Health goals were related to disease prevention and symptom control, family well-being, own quality of life, own or family members’ work and/or financial situation. Life goals concerned family well-being, their own quality of life, work/financial situation and health. Given the limited time health professionals have with their patients, trained community volunteers could be important members of primary care teams caring for immigrants.
Vision models fine-tuned by cinema professionals for High Dynamic Range imaging in movies
Authors: Cyriac Praveen , Canham Trevor , Kane David , Bertalmío Marcelo 
Published: September 2020

AbstractMany challenges that deal with processing of HDR material remain very much open for the film industry, whose extremely demanding quality standards are not met by existing automatic methods. Therefore, when dealing with HDR content, substantial work by very skilled technicians has to be carried out at every step of the movie production chain. Based on recent findings and models from vision science, we propose in this work effective tone mapping and inverse tone mapping algorithms for production, post-production and exhibition. These methods are automatic and real-time, and they have been both fine-tuned and validated by cinema professionals, with psychophysical tests demonstrating that the proposed algorithms outperform both the academic and industrial state-of-the-art. We believe these methods bring the field closer to having fully automated solutions for important challenges for the cinema industry that are currently solved manually or sub-optimally. Another contribution of our research is to highlight the limitations of existing image quality metrics when applied to the tone mapping problem, as none of them, including two state-of-the-art deep learning metrics for image perception, are able to predict the preferences of the observers.
An Optimal Approach for Land-Use / Land-Cover Mapping by Integration and Fusion of Multispectral Landsat OLI Images: Case Study in Baghdad, Iraq

Published: September 2020

AbstractUsing solely an optical remotely sensed dataset to obtain an accurate thematic map of land use and land cover (LU/LC) is a serious challenge. The dataset fusion of multispectral and panchromatic images play a big role and provide an accurate estimation of LU/LC map simply because using a dataset from different spectrum portions with different spatial and spectral characteristics will improve image classification. For this study, the Landsat operational land imager multispectral and panchromatic images were adopted. This study aimed to investigate the effectiveness of using a panchromatic highly spatial resolution to refine the methodology for LU/LC mapping in Baghdad city, Iraq, by performing a comparison of classifications using different algorithms on multispectral and fused images. Different classification algorithms were employed to classify the data set; minimum distance (MD) and the maximum likelihood classifier (MLC). A suitable classification method was proposed to map LU/LC based on the outcome results. The result evaluation was conducted by applying a confusion matrix. An overall accuracy of a fused image using a principal component-based spectral sharpening algorithm and classified by the MLC classifier reveals the highest accurate results with an overall accuracy and kappa coefficient of 98.90% and 0.98, respectively. Results showed that the best methodology for LU/LC mapping of the study area is found from fusion of multispectral with panchromatic images via principal component-based spectral algorithm with MLC approach for classification.
Do earthworms (D. veneta) influence plant-available water in technogenic soil-like substrate from bricks and compost?

Abstract
Purpose
Topsoil and peat are often taken from intact rural ecosystems to supply the urban demand for fertile soils and soil-like substrates. One way of reducing this exploitation is to recycle suitable urban wastes to produce Technosols and technogenic soil-like substrates. In this study, we investigate the role earthworms can play in impacting the hydraulic properties of such a soil-like substrate.

Materials and methods
In a 4-month microcosm experiment, the influence of the earthworm species D. veneta on the hydraulic properties of brick-compost mixture was examined. Of the ten boxes filled with ca. 11 dm3 of ground bricks (0.7 cm3 cm−3) and green waste compost (0.3 cm3 cm−3), five contained earthworms (W-boxes) and the remaining five were used as controls (C-boxes). The substrate was periodically irrigated and the weight of the boxes and of the drained water was monitored. At the same time, images were taken from the front of the boxes to quantify the activity of the earthworms by image analysis and soil aggregation was studied with micrographs. Before and after the experiment, water retention curves were determined from disturbed samples of the substrate using the simplified evaporation method.

Results and discussion
After 6 weeks, differences between the C- and the W-boxes were evident. Micrographs showed brick-compost aggregates only for the substrates processed by earthworms. The earthworm activity leads to reduced evaporation and an increased water content in the respective microcosms. The effect persists even after disturbing the substrate. The proportion of plant-available soil water is about 0.02 cm3 cm−3 higher for the substrate processed by earthworms (0.250 ± 0.009 cm3 cm−3) compared with the control (0.230 ± 0.008 cm3 cm−3).

Conclusions
This study shows that earthworms are capable of ingesting and processing crushed bricks together with compost. The earthworms produced aggregates which persisted after disturbance and had a positive influence on the water retention capacity of such a soil-like substrate constructed from waste.
