Chalcopyrite solar cells —state-of-the-art and options for improvement
Authors: Siebentritt S. , Weiss T. P. 
Published: December 2022

AbstractChalcopyrite solar cells will have to play an important role to mitigate the climate crisis, because of their particularly low carbon emissions. Doping in these semiconductors is due to native defects and intentional alkali impurities. The recent progress in efficiency has been made possible by post-deposition treatments with heavy alkalis. Tail states and band gap distribution are the main limitations for the open circuit voltage in state-of-the-art chalcopyrite solar cells. Further efficiency limitations are due to the increased diode factor because of metastable defect transitions. Alloying with Ag opens new possibilities of band-edge engineering, as well as seems to improve the diode factor. In state-of-the-art cells the back contact is passivated by a Ga gradient; considerable research has been done to passivate the back contact by structured or continuous dielectric layers. A leap forward in efficiency can be expected from tandem cells. Chalcopyrite solar cells show promising potential as bottom cells as well as top cells.

Abstract

Background

Sleeve dilatation after laparoscopic sleeve gastrectomy (LSG) causes weight regain (WR). Banded sleeve gastrectomy (BSG) was proposed to prevent dilatation and reduce WR.

Methods
A retrospective cohort study on patients who underwent BSG and LSG and completed 4 years of follow-up from 2016 to 2021 was included. Body mass index (BMI), percentage of excess weight loss (%EWL), percentage of total weight loss (%TWL), and FT scores were calculated at 1, 2, 3, and 4 years. The sleeve volume was estimated at 6 months, 1 year, and 4 years. Multi-variate analysis was conducted to assess correlations between covariates. WR was calculated as weight gain > 10%, > 10 kg above the nadir, or BMI increase of ≥ 5 kg/m 2 above the nadir.

Results
This study included LSG 1279 patients and BSG 132 patients. Mean %EWL at 1 year was 83.87 ± 17.25% in LSG vs. 85.71 ± 7.92% in BSG and was 83.47 ± 18.87% in LSG and 85.54 ± 7.48% in BSG at 4 years. Both had significant weight loss over time (p. < 0.001) with no significant main effect of surgery (p.0.438). Mean sleeve volume at 6 months was 102.32 ± 9.88 ± 10.28 ml in LSG vs. 101.89 ± 10.019 ml in BSG and at 4 years was 580.25 ± 112.25 ml in LSG vs. 157.94 ± 12.54 ml in BSG (p. < 0.001).
WR occurred in 136 (10.6%) and 4 (3.1%) (p.0.002) in LSG and BSG patients, 90 (7%) vs. zero (0%) (p.0.002) and 31 (2.4%) vs. zero (0%) (p.0.07) using the > 10%, > 10 kg increase above the nadir and the ≥ 5 kg/m 2 BMI increases above the nadir formulas, respectively.

Conclusion
BSG had significantly lower sleeve volume, significantly lower WR, and significantly lower FT scores than LSG after 4 years from surgery; however, volume changes were not correlated with weight loss.

AbstractBackgroundIn January 2021, the Diamondback 360 orbital atherectomy (OA) system received CE mark approval and became available in Europe. The first procedure in Europe was performed at the Thoraxcenter, Erasmus Medical Center, Rotterdam, the Netherlands.AimsTo report the procedural safety and efficacy of the initial experience with OA in a tertiary care institution in the Netherlands.MethodsPatients with de novo severely calcified coronary artery disease who were treated with intended invasive imaging-guided OA were included in a prospective single-centre registry. Device success, defined as less than 50% stenosis after OA, and procedural success, defined as successful stent implantation with less than 50% residual stenosis, were evaluated. Calcium debulking effects were assessed by invasive imaging. Safety was assessed up to 30 days after the index procedure.ResultsBetween February 2021 and June 2021, 29 patients with a total of 39 coronary arteries underwent OA. Target lesions were heavily calcified with a mean length of 32 mm and a calcium arc of 320 degrees. Invasive imaging was applied in all but one patient and 36 vessels. Superficial sanding was observed in almost all vessels (90%) and fracturing of deeper medial calcium in more than half of the vessels (63%), with a device success of 66% and procedural success of 94%. The mean stent symmetry index was 0.84, indicating good circular stent expansion. No primary safety events occurred during 30 days of follow-up.ConclusionOur initial experience with OA for heavily calcified coronary lesions demonstrated favourable debulking effects and plaque modification, with high procedural success and clinical safety.
Designing a feature selection method based on explainable artificial intelligence
Authors: Zacharias Jan , von Zahn Moritz , Chen Johannes , Hinz Oliver 
Published: December 2022

AbstractNowadays, artificial intelligence (AI) systems make predictions in numerous high stakes domains, including credit-risk assessment and medical diagnostics. Consequently, AI systems increasingly affect humans, yet many state-of-the-art systems lack transparency and thus, deny the individual’s “right to explanation”. As a remedy, researchers and practitioners have developed explainable AI, which provides reasoning on how AI systems infer individual predictions. However, with recent legal initiatives demanding comprehensive explainability throughout the (development of an) AI system, we argue that the pre-processing stage has been unjustifiably neglected and should receive greater attention in current efforts to establish explainability. In this paper, we focus on introducing explainability to an integral part of the pre-processing stage: feature selection. Specifically, we build upon design science research to develop a design framework for explainable feature selection. We instantiate the design framework in a running software artifact and evaluate it in two focus group sessions. Our artifact helps organizations to persuasively justify feature selection to stakeholders and, thus, comply with upcoming AI legislation. We further provide researchers and practitioners with a design framework consisting of meta-requirements and design principles for explainable feature selection.

AbstractPopulation aging resulting from demographic changes requires some challenging decisions and necessary steps to be taken by different stakeholders to manage current and future demand for assistance and support. The consequences of population aging can be mitigated to some extent by assisting technologies that can support the autonomous living of older individuals and persons in need of care in their private environments as long as possible. A variety of technical solutions are already available on the market, but privacy protection is a serious, often neglected, issue when using such (assisting) technology. Thus, privacy needs to be thoroughly taken under consideration in this context. In a three-year project PAAL (‘Privacy-Aware and Acceptable Lifelogging Services for Older and Frail People’), researchers from different disciplines, such as law, rehabilitation, human-computer interaction, and computer science, investigated the phenomenon of privacy when using assistive lifelogging technologies. In concrete terms, the concept of Privacy by Design was realized using two exemplary lifelogging applications in private and professional environments. A user-centered empirical approach was applied to the lifelogging technologies, investigating the perceptions and attitudes of (older) users with different health-related and biographical profiles. The knowledge gained through the interdisciplinary collaboration can improve the implementation and optimization of assistive applications. In this paper, partners of the PAAL project present insights gained from their cross-national, interdisciplinary work regarding privacy-aware and acceptable lifelogging technologies.
Recombinant Human Perlecan DV and Its LG3 Subdomain Are Neuroprotective and Acutely Functionally Restorative in Severe Experimental Ischemic Stroke

Published: December 2022

AbstractDespite recent therapeutic advancements, ischemic stroke remains a major cause of death and disability. It has been previously demonstrated that  ~ 85-kDa recombinant human perlecan domain V (rhPDV) binds to upregulated integrin receptors (α2β1 and α5β1) associated with neuroprotective and functional improvements in various animal models of acute ischemic stroke. Recombinant human perlecan laminin-like globular domain 3 (rhPDVLG3), a 21-kDa C-terminal subdomain of rhPDV, has been demonstrated to more avidly bind to the α2β1 integrin receptor than its parent molecule and consequently was postulated to evoke significant neuroprotective and functional effects. To test this hypothesis, fifty male C57Bl/6 J mice studied in a t-MCAO model were randomly allocated to either rhPDV treatment, rhPDVLG3, or equivalent volume of PBS at the time of reperfusion in a study where all procedures and analyses were conducted blind to treatment. On post-MCAO day 7, 2,3,5-triphenyltetrazolium chloride staining of brain slices was used to quantify infarct volume. We observed that treatment with rhPDVLG3 reduced infarct volume by 65.6% (p = 0.0001), improved weight loss (p < 0.05), and improved functional outcome measures (p < 0.05) when compared to PBS controls, improvements which were generally greater in magnitude than those observed for 2 mg/kg of rhPDV. In addition, treatment with 6 mg/kg of rhPDVLG3 was observed to significantly reduce mortality due to stroke in one model, an outcome not previously observed for rhPDV. Our initial findings suggest that treatment with rhPDVLG3 provides significant improvement in neuroprotective and functional outcomes in experimental stroke models and that further investigation of rhPDVLG3 as a novel neuroprotective therapy for patients with stroke is warranted.
Biases in COVID-19 Case and Death Definitions: Potential Causes and Consequences
Authors: Brown Ronald B. 
Published: December 2022

Abstract
This paper investigates three controversies involving potential causes and consequences of information bias in case and death definitions during the coronavirus disease (COVID-19) pandemic. First, evidence suggests China’s surveillance data were biased and misinterpreted by the World Health Organization (WHO), prompting the WHO to advise nations to copy China’s lockdowns. China appeared to use narrow diagnostic definitions that undercounted cases and deaths. Second, novel genomic data disseminated during the pandemic without adequate guidance from rigorous epidemiologic studies biased infection control policies in many countries. A novel genomic sequence of a virus is insufficient to declare new cases of a novel disease. Third, media reports of COVID-19 surveillance data in many nations appeared to be biased. Broadened surveillance definitions captured additional information, but unadjusted surveillance data disseminated to the public are not true cases and deaths. Recommendations include clarification of the proper use of diagnostic and surveillance case and death definitions to avoid information bias.

Published: December 2022

Abstract
After the Fukushima accident in 2011, approximately 160000 residents were forced to evacuate the site. The evacuation order has since been lifted and the Japanese government is now advancing a return strategy. As the return proceeds, deterioration of health indicators and measures in the municipalities around the nuclear power plant remains unchanged. This affected the local governments’ coronavirus disease (COVID-19) vaccination drive during the COVID-19 pandemic. In Japan, municipalities keep track of residents’ information and implement health-related measures. However, many residents evacuated the town, thus leaving their registered residence. With long-term evacuation and few returnees, it was difficult for government officials to constantly monitor the residents’ health. Therefore, there is an urgent need to maintain residents’ records and ensure that they receive health services without any gap. This report aimed to provide implications for post-disaster community health services and support as observed during the COVID-19 vaccination program at a disaster site.
Contested Caryatids: Architecture, Modernity, and Race around 1900
Authors: Jütte Daniel 
Published: December 2022

AbstractIn the nineteenth century, caryatids saw an unprecedented renaissance in European architecture. This article explores the cultural history of these female column-statues in nineteenth- and early-twentieth-century Europe. The focus is on central Europe, and three cities—Berlin, Frankfurt am Main, and Vienna—play a particularly important role in this exploration. Through a reading of historical, visual, and literary sources, the article probes how these statues came to embody, on both a material and a metaphorical level, the social aspirations and societal rifts that marked the bourgeois age. The nexus, real and imagined, between caryatids and Jews is particularly illustrative here. In tracing antagonistic and largely forgotten discourses, the article seeks to shed light on a larger subject that is still underexplored: the complex entanglement of architecture, religion, and race in the long nineteenth century.

Published: December 2022

AbstractIndustrial robots are widely used in the painting industry, such as automobile manufacturing and solid wood furniture industry. An important problem is how to improve the efficiency of robot programming, especially in the current furniture industry with multiple products, small batches and increasingly high demand for customization. In this work, we propose an outer loop adaptive control scheme, which allow users to realize the practical application of the zero-moment lead-through teaching method based on dynamic model without opening the inner torque control interface of robots. In order to accurately estimate the influence of joint friction, a friction model is established based on static, Coulomb and viscous friction characteristics, and the Sigmoid function is used to represent the transition between motion states. An identification method is used to quickly identify the dynamic parameters of the robot. The joint position/speed command of the robot’s inner joint servo loop is dynamically generated based on the user-designed adaptive control law. In addition, the zero-moment lead-through teaching scheme based on the dynamic model is applied to a spray-painting robot with closed control system. In order to verify our method, CMA GR630ST is used to conduct experiments. We identified the parameters of the dynamic model and carried out the zero-moment lead-through teaching experiment to track the target trajectory. The results show that the proposed method can realize the application of modern control methods in industrial robot with closed control systems, and achieve a preliminary exploration to improve the application scenarios of spray-painting robots.

Published: December 2022

AbstractChildren differ in their environmental sensitivity (ES), which can be measured observationally or by self-report questionnaire. A parent-report scale represents an important tool for investigating ES in younger children but has to be psychometrically robust and valid. In the current multistudy, we validated the parent-report version of the Highly Sensitive Child (HSC-PR) scale in Italian children, evaluating its factorial structure (Study 1, N = 1,857, 6.2 years, age range: 2.6–14 years) through a multigroup Confirmatory Factory Analysis in preschoolers (n = 1,066, 4.2 years) and school-age children (n = 791, 8.8 years). We then investigated the HSC-PR relationship with established temperament traits (Study 2, N = 327, 4.3 years), before exploring whether the scale moderates the effects of parenting stress on children’s emotion regulation (Study 3, N = 112, 6.5 years). We found support for a bi-factor structure in both groups, though in preschoolers minor adaptations were suggested for one item. Importantly, the HSC-PR did not fully overlap with common temperament traits and moderated the effects of parenting stress on children emotion regulation. To conclude, the HSC-PR performs well and appears to capture ES in children.

AbstractLet H be an ultraspherical hypergroup and let

be the Fourier algebra associated with
$H.$
In this paper, we study the dual and the double dual of
$A(H).$
We prove among other things that the subspace of all uniformly continuous functionals on
$A(H)$
forms a

-algebra. We also prove that the double dual
$A(H)^{\ast \ast }$
is neither commutative nor semisimple with respect to the Arens product, unless the underlying hypergroup H is finite. Finally, we study the unit elements of
$A(H)^{\ast \ast }.$
A Modeling Perspective on the Lingering Glacial Sea Surface Temperature Conundrum
Authors: Krätschmer S. , Cauquoin A. , Lohmann G. , Werner M. 
Published: December 2022

AbstractThe strong cooling during the Last Glacial Maximum (LGM, 21 ka BP) provides a rigorous test of climate models' ability to simulate past and future climate changes. We force an atmospheric general circulation model with two recent global LGM sea surface temperature (SST) reconstructions, one suggesting a weak and the other a more pronounced cooling, and compare the simulated land surface temperatures (LSTs) to reconstructed data. Our results do not confirm either SST reconstruction. The cold SST data set leads to good agreement between simulated and observed LSTs at low latitudes, but is systematically too cold at mid‐latitudes. The opposite is true for the warm SST data set. Differences between the simulated LSTs are caused by varying land surface albedos, which is lower for the warmer SST reconstruction. The inconsistency between reconstructed and simulated climate points to a potentially significant bias in the proxy reconstructions and/or the climate sensitivity of current climate models.
Satellite‐Borne Observations of Ozone Impact by the November 2001 Solar Proton Event

Published: December 2022

AbstractThe November 2001 Solar Proton Event (SPE) is one of the strongest events in the era of satellite observations. However, no observational case study of this exceptional event's impact on atmospheric chemistry has been reported. In this paper, we use satellite‐based observations from Optical Spectrograph and Infrared Imaging Systems (OSIRIS) to quantify the SPE impact on middle atmospheric O3 in the southern hemisphere during summertime conditions. The results show a relatively modest, yet detectable, O3 depletion in the upper stratosphere and lower mesosphere. Compared to the observations, the Whole Atmosphere Community Climate Model (WACCM‐D) simulates somewhat lower O3 levels before the event but captures well the relative ozone depletion. The largest depletion is seen on November 6th, after the Geostationary Operational Environment Satellite observed the peak proton fluxes. On this day, the O3 depletion was observed and simulated from the pole to 55°S geographic latitude. The daily polar cap (poleward of 60°S geographic latitude) averaged O3 profiles show a maximum depletion of 16.6 ± 2.2% at 1 hPa and 18.8 ± 3.3% at 1.5 hPa altitude, by OSIRIS and WACCM‐D, respectively. After the SPE, an enhancement in NOx is simulated by the results of the model within altitudes of the observation, which is well correlated with the observed and modeled O3 depletion. Challenges related to the detection of SPE impact on O3 in the summer hemisphere are discussed. We find that a careful analysis of simulation results can be essential when isolating the SPE impact from background variation.
Expectations, concerns, and attitudes regarding whole-genome sequencing studies: a survey of cancer patients, families, and the public in Japan

Published: December 2022

AbstractWhole-genome sequencing (WGS) is being used in research and clinical settings in cancer genomics. Studies show that cancer patients generally have positive attitudes toward tumor profiling tests; however, few works revealed their attitudes toward WGS. This study clarifies the expectations, concerns, and result preferences of cancer patients (CPs), family members (FMs) and general adults (GAs) regarding WGS study in Japan. We conducted an anonymous survey with 1204 CPs, 5958 FMs, and 2915 GAs in 2021. Despite low awareness of the WGS studies, CPs had the highest expectations for it. FMs had a higher level of concern than CPs and GAs; feeling anxious by knowing the results, being treated unfavorably if germline findings were detected. Both the FMs and CPs were highly concerned about the protection of genetic information. CPs preferred results with actionability, however, only half preferred to know germline findings. Given the possibility of detecting variants across multidisciplinary diseases and the long-term continuity of WGS research, a system is needed in which study participants can consult and receive decision-making support at any time according to their needs.

AbstractUltrahigh-resolution patterning with high-throughput and high-fidelity is highly in demand for expanding the potential of organic light-emitting diodes (OLEDs) from mobile and TV displays into near-to-eye microdisplays. However, current patterning techniques so far suffer from low resolution, consecutive pattern for RGB pixelation, low pattern fidelity, and throughput issue. Here, we present a silicone engineered anisotropic lithography of the organic light-emitting semiconductor (OLES) that in-situ forms a non-volatile etch-blocking layer during reactive ion etching. This unique feature not only slows the etch rate but also enhances the anisotropy of etch direction, leading to gain delicate control in forming ultrahigh-density multicolor OLES patterns (up to 4500 pixels per inch) through photolithography. This patterning strategy inspired by silicon etching chemistry is expected to provide new insights into ultrahigh-density OLED microdisplays.
