Identification of Everyday Proxies for Tangible Augmented Reality

Using everyday objects as proxies for interaction with virtual objects is a good way to take advantage of tangible interaction without having exact replicas on hand. Since it is not possible to have the exact physical replica in place for every application, everyday objects located in the environment must be identified that are suitable for interaction. The objects must be such that interaction with them feels as realistic as possible and the user experience is not significantly worse compared to interaction with an exact replica. While there are already several studies on this in VR and video see-through AR, very little research has been done in the area of optical see-through AR, although this area is becoming more and more prominent.
Presenting CS Concepts through Multiple Representations to Engage African-American Elementary School Children

— This experience report presents elements of an outreach program to elementary school children to broaden participation in computing. The program is based on a unique multi-faceted curriculum that facilitates the presentation of abstract computer science (CS) concepts within a summer camp setting. The curriculum exposes the same abstract content to children using different representations and helps them to learn and practice the concepts using a “hands-on” approach. Further, use of multiple representations supports the learning needs of diverse learners, considering the grades and ages of the participants. Speciﬁcally, we present CS concepts to students in three formats: 1) using motivated real-world and everyday examples, 2) elementary graphical programming, and 3) a custom video game designed to test and exercise concepts in a fun environment. Pretest/posttest analysis show promising trends, including positive changes in attitudes and learning of computational thinking and coding concepts.
EFFECT OF ENTITY MOBILITY MODELS ON REACTIVE PROTOCOL IN MOBILE AD HOC NETWORKS

— Mobile Ad hoc Networks (MANETs) belong to Wireless Networks where the nodes communicate with each other in a multi-hop fashion without any centralized control. In these networks, the dynamic topology of nodes, interference, path loss and multipath propagation. So, it does not require an infrastructure to resume the network connectivity. This infrastructure less, resource constrained, with limited memory and computing capacity along with the dynamic topology of MANET, demands different network strategies to be implemented to accomplish the communication. Considering all these issues, routing performs a crucial role while computing the path from source to the destination. Further, Mobility modeling and control makes the topology of MANET more challenging which requires considerable human focus. To handle this scenario, different solutions have been presented by many potential researchers. This paper attempts to focus on the performance of reactive routing protocol AODV by considering different entity mobility models by using OPNET Simulator viewing that applicability of the protocol can be enhanced. So, this paper measures some performances such as End to End delay, Throughput and Routing Overhead of MANET.
Audit risk calibration : Extending the Non-GAAP SEC-Filter

AS5[v.Dec:2017] issued by the Public Company Accounting Oversight Board [PCAOB] requires the use of Analytical Procedures [AP] at the Planning and Substantive Phases of Assurance Audits for firms traded on active exchanges. We argue that one aspect of AP, relative to risk-setting, should be vetting the information that is produced/published by the audit client pertaining to Regulation G [v.SEC:2003] called: Non-GAAP information. In our research, we intend to leverage the longstanding Reg[G] requirements to extend the Non-GAAP information to firm performance profiles reported for the Environment, Social, and Governance[ESG]Platform on BloombergTM. There are two research foci: (1) Offer an AP-Model that uses GAAP & ESG variables to contribute audit evidence useful in making the decision to launch an AP-Extended Procedures examination of the firm’s Enterprise Resource Planning & Control [ERP&C] protocols, and (2) Profile a random accrual-set of firms indexed on Bloomberg so as to offer population parameter estimates for refining the AP-Model. The AP-Model is based upon correlational associations for the ESG& GAAP-variables from the: Income, Balance Sheet & Cash Flow Statements. If there seems to be a disconnect between the nature of these associations for the ESG-variables and those of the GAAP-variables, the auditor may use this as audit evidence in making the decision to conduct an Extended Procedures Examination of the firm’s [ERP&C] protocols. As for the other focus, we found that for the accrual of firms tested there is no inferential evidence that the ERP&C-protocols are consistent drivers for both the ESGand the GAAP variable sets. © 2020 by the authors.

Are US Life Insurers the New Shadow Banks?

We show that the largest U.S. life insurers entered corporate loan markets as banks refocused on commercial banking from 2009, against a backdrop of unconventional monetary policies and tighter bank regulations. Through complex on- and off-balance sheet arrangements, these insurers, many of whom are controlled by private equity firms, are acquiring and deploying vast amounts of insurance liabilities to fill the void left by banks. Using the COVID-19 pandemic, we show that life insurers have become more vulnerable to an aggregate shock to the corporate sector and disproportionately benefited from the Fed response to the pandemic.
The Economics of Natural Gas Venting, Flaring and Leaking in U.S. Shale: An Agenda for Research and Policy

Natural gas venting, flaring and leaking (VF&L) are closely intertwined environmental policy issues for U.S. shale oil and gas operations. In this paper, we lay out an agenda for researchers and policymakers. We describe why VF&L are closely related, both physically and in terms of policy. We perform an interdisciplinary literature review on measurement of VF&L. We marshal granular industry data to identify constraints in the natural gas system correlated with upstream VF&L. Motivated by this descriptive analysis, we discuss the economic reasons for VF&L and the market distortions that could exacerbate VF&L. We then discuss the external cost of VF&L. We calculate that reported 2015 and 2019 flaring and venting imposed climate damages of $0.9 to $1.8 billion and $1.7 to $3.4 billion. We calculate that climate damages of 2015 upstream U.S. methane emissions estimated by Alvarez et al. (2018) were $16.8 billion. Finally, we discuss both existing policy and economic insights relevant to future policy.
Hypericum perforatum subsp. angustifolium: study of xanthone biosynthesis in planta and in in vitro systems

Das Ziel der vorliegenden Arbeit war die Untersuchung der Xanthonbiosynthese innerhalb der Pflanze, sowie in in vitro Systemen von Hypericum perforatum subsp. angustifolium (Hpa), eine seltene Subspezies, die reich an Sekundarmetaboliten ist. Xanthone sind bioaktive Polyketide, die durch die Benzophenonsynthase (BPS) synthetisiert werden. Phytochemische Analysen konnten zeigen, dass Xanthon hauptsachlich in den Wurzeln der Pflanze akkumuliert werden und ihre Gegenwart abhangig von Umweltfaktoren ist. Pflanzenwurzeln, welche unter kontrollierten Bedingungen angezogen wurden und in vitro regenerierte Wurzeln zeigten einen stabilen und signifikant hoheren Xanthonegehalt im Vergleich zu wild gewachsenen Pflanzen. Extrakten von in vitro-Wurzeln konnte antifungale Aktivitat gegen die pilzlichen Humanpathogenen Candida spp. , Cryptococcus neoformans und Dermatophyten nachgewiesen werden. Die Optimierung der Wurzelkultivierungsbedingungen konnte mit Hilfe des halbsynthetischen Carboxymethylchitosans (CMC) als Induktor der Xanthonbiosynthese erreicht werden. Durch bioassaygesteuerte Fraktionierung konnte Bioyouxanthon D isoliert und als die wichtigste aktive Komponente gegen Dermatophyten und C. neoformans identifiziert werden. Da Chitosan die Expression des Benzophenonsynthase-kodierenden Gens induzierte, wurde ein BPS-Transkript aus induzierten adventiven Wurzeln kloniert, in E. coli exprimiert und funktional charakterisiert. Genexpressionsanalysen durch in situ Hybridisierungsexperimente zeigten, dass die Expression von bps gewebespezifisch ist und im ersten kortikalen Parenchym lokalisiert ist, sowie auch schwacher in der Endodermis. Zusammenfassend deckte diese Studie auf, dass Xanthonbiosynthese und –anreicherung in Hpa in den Wurzeln stattfindet. Ausserdem wurde gezeigt, dass Xanthon aus Hpa aktiv gegen humanpathogene Pilze ist und dass in vitro-Wurzeln ein vielversprechendes System fur die Produktion von Extrakten fur Anwendungszwecke in der Formulierung therapeutischer Medikamente darstellt.
Surviving Sepsis Campaign: Research Opportunities for Infection and Blood Purification Therapies

OBJECTIVES: Patients with infection can develop sepsis, and their mortality can be high. An important aspect in the treatment of sepsis is adequate management of the infection. DATA SOURCES: Using a modified Delphi approach, the Surviving Sepsis Campaign research committee recently published a series of 26 priorities for sepsis and septic shock. STUDY SELECTION: Task force members with specific expertise were tasked with generating expanded reviews for all infection questions and a subset of adjunctive therapy questions from the larger list of sepsis priorities. Each question was addressed by one of the six task force members. DATA EXTRACTION: In-depth reviews were then edited by the group as a whole, with added input from the committee cochairs. DATA SYNTHESIS: Six questions were addressed: 1) should empiric antibiotic combination therapy be used in sepsis or septic shock? 2) does optimization of antimicrobial pharmacokinetics and pharmacodynamics impact patient outcomes in sepsis? 3) should viral reactivation resulting from sepsis-induced immunosuppression be treated with antiviral therapy in critically ill septic patients? 4) should rapid diagnostic tests be implemented in clinical practice? 5) what is the role of lung-protective ventilation in sepsis patients without acute respiratory distress syndrome? and 6) how do we determine the efficacy of “blood purification” therapies such as endotoxin absorbers, cytokine absorbers, and plasmapheresis. CONCLUSIONS: The research committee members for the Surviving Sepsis Campaign aimed to explore research questions in order to provide existing evidence and highlight areas of uncertainty and future directions.
Acetylcholine esterase inhibitory activity of green synthesized nanosilver by naphthopyrones isolated from marine-derived Aspergillus niger

Aspergillus niger metabolites exhibited a wide range of biological properties including antioxidant and neuro-protective effects and some physical properties as green synthesis of silver nanoparticles AgNP. The present study presents a novel evidence for the various biological activities of green synthesized AgNPs. For the first time, some isolated naphtho-γ-pyrones from marine-derived Aspergillus niger, flavasperone (1), rubrofusarin B (2), aurasperone A (3), fonsecinone A (4) in addition to one alkaloid aspernigrin A (7) were invistigated for their inhibitory activity of acetylcholine esterase AChE, a hallmark of Alzheimer’s disease (AD). The ability to synthesize AgNPs by compounds 3, 4 and 7 has been also tested for the first time. Green synthesized AgNPs were well-dispersed, and their size was ranging from 8–30 nm in diameter, their morphology was obviously spherical capped with the organic compounds. Further biological evaluation of their AChE inhibitory activity was compared to the parent compounds. AgNps dramatically increased the inhibitory activity of Compounds 4, 3 and 7 by 84, 16 and 13 fold, respectively to be more potent than galanthamine as a positive control with IC50 value of 1.43 compared to 0.089, 0.311 and 1.53 of AgNPs of Compounds 4, 3 and 7, respectively. Also compound 2 showed moderate inhibitory activity. This is could be probably explained by closer fitting to the active sites or the synergistic effect of the stabilized AgNPs by the organic compouds. These results, in addition to other intrinsic chemical and biological properties of naphtho-γ-pyrones, suggest that the latter could be further explored with a view towards other neuroprotective studies for alleviating AD.
No tillage and residue mulching method on bacterial community diversity regulation in a black soil region of Northeastern China

Soil microorganisms are important components of agricultural ecosystems; they are important in agricultural soil nutrient cycle and are easily affected by soil tillage. The response of soil microbial community to tillage is very complex, and the effect of the no tillage and residue mulching method on soil microbial diversity remains unclear. In 2019, the soil was collected from an experimental field after 10 years of continuous cultivation in the black soil area of the Sanjiang Plain in Northeastern China. In this study, the diversity and composition of the soil bacterial community and their relationship with soil properties were explored via high-throughput sequencing under no tillage with four residue mulching treatments. No tillage with 60% residue mulching (NTR3) significantly increased the alpha diversity of the rhizosphere soil bacteria and changed the composition of the bacterial community—consistent with changes in soil physicochemical properties. Proteobacteria, Acidobacteria, and Actinobacteria were the dominant phyla in the sample soil. Soil physicochemical properties explained 80.6% of the changes in soil diversity and composition, of which soil organic carbon, soil pH, and soil temperature were the principal contributors. Our results suggest that no tillage and residue mulching is conducive to increasing soil organic carbon and soil nutrient content, which is a beneficial conservation tillage measure for black soil protection in Sanjiang Plain of Northeast China. The no tillage with residue mulching, especially 60% residue mulching, alters soil bacterial community and highlights the importance of soil physicochemical properties in shaping the diversity and composition of the soil bacterial community. Our findings contribute to a broad understanding of the effects of no tillage and residue mulching on bacterial community differences and provide a scientific basis for the optimization of no tillage measures and sustainable utilization of the black soil of the Sanjiang Plain in Northeastern China.
Coupling coordination relationship between ecosystem services and water-land resources for the Daguhe River Basin, China

Water and land resource utilization is an important driving force of changes in ecosystem services; therefore, research on multi-parameter coupling systems that consider “ecosystem services, water resources, and land resources” together has key significance for river basins. This study aims to reveal the interaction and mutual influence of ecosystem services and water and land resources in the Daguhe River Basin, China, based on the coupling coordination degree model. The results showed that during the period from 2000 to 2010, the coupling coordination degree values for the years 2000, 2005, and 2010 were 0.6005, 0.7292, and 0.8037. The corresponding coupling coordination classifications were categorized as “primary coordinated development”, “intermediate coordinated development,” and “well-coordinated development”, respectively. These results reflected the fact that the relationship between water and land resource utilization and the environment tends to evolve in the direction of coordinated development (an improvement in one part corresponds to an improvement in another part) with variation in water and land utilization types, and eventually pushes the whole resource, as well as ecological and environmental systems, from low to high levels of coupling coordination degrees as observed in case of the Daguhe River Basin, China. Our research provides an overview of the interaction between ecosystem services and water and land resources in the Daguhe Basin and even in the Shandong Province. With our results, we offer new perspectives on river basin management and for planning future eco-environmental policies (the policy is specifically designed for the ecological environment) by combining water and land resource utilization.
Nature and Location of Carbonaceous Species in a Composite HZSM-5 Zeolite Catalyst during the Conversion of Dimethyl Ether into Light Olefins

The deactivation of a composite catalyst based on HZSM-5 zeolite (agglomerated in a matrix using boehmite as a binder) has been studied during the transformation of dimethyl ether into light olefins. The location of the trapped/retained species (on the zeolite or on the matrix) has been analyzed by comparing the properties of the fresh and deactivated catalyst after runs at different temperatures, while the nature of those species has been studied using different spectroscopic and thermogravimetric techniques. The reaction occurs on the strongest acid sites of the zeolite micropores through olefins and alkyl-benzenes as intermediates. These species also condensate into bulkier structures (polyaromatics named as coke), particularly at higher temperatures and within the meso- and macropores of the matrix. The critical roles of the matrix and water in the reaction medium have been proved: both attenuating the effect of coke deposition.
Plain Radiographs Can Safely Be Used to Measure and Follow Up on Tibial Component Alignment in Unicondylar Knee Replacement: A Correlation Study With CT Scans

Background and objective Unicondylar knee replacement (UKR) is one of the most frequently performed arthroplastic operations worldwide. Migration and subsidence regarding the tibial component of UKR is a well-known phenomenon. In this study, we aimed to analyze whether plain radiographs are a reliable means to measure the true coronal and sagittal alignment of the UKR’s tibial component. Methods Patients undergoing a UKR procedure at our center between December 2020 and March 2011 were eligible for this study. Inclusion criteria were as follows: the presence of well-aligned standard and reproducible anteroposterior and lateral X-rays taken one week before or after a low-radiation artifact-reduced CT scan. Sixty-six knees were included in the study. Coronal and sagittal alignment of the tibial component was measured in a standard manner by two observers on both X-rays and CT scans. A correlation analysis was performed, and the margin of error was established. Results Intra-observer reliability was high among the two observers whether for X-ray or CT scan measurements [intraclass correlation coefficient (ICC): >0.900]. On the other hand, coronal plane measurements had lower inter-observer ICC values on both X-rays and CT scans while reliability on the sagittal plane was higher. There was a high correlation between radiographic measurements on X-rays and CT scans on both planes. Conclusion Even though the measurements on plain radiographs were slightly different from the ones obtained from CT scans, the correlation between them was very strong. Caution should be exercised when measuring the coronal alignment of the tibial implant on X-rays since it is more frequently affected by rotational misalignment.
Gender Differences in the Effect of Workplace Loneliness on Organizational Citizenship Behaviors Mediated by Work Engagement

Purpose Drawing on the self-determination theory and the social role theory, the purpose of this study was to test the moderating role of gender and the mediating role of work engagement in the relationship between workplace loneliness and organizational citizenship behaviors (OCBs), and more importantly, the integrated moderated mediation model. Methods A total of 290 employees from various Chinese enterprises voluntarily participated in the two-wave surveys. Hierarchical regression and bootstrapping analyses based on Hayes’ Process Model were conducted to test the hypotheses. Results Results indicated that work engagement significantly mediates the association of workplace loneliness with OCBs. Gender serves as an important moderator in the relationship among workplace loneliness, work engagement, and OCBs that for female participants the indirect effect of work engagement linking workplace loneliness to OCBs was significant, but for male participants it was not. Conclusion This study advances the current understandings of the moderated mediation mechanism among workplace loneliness, gender, work engagement, and OCBs. It is suggested that work engagement serves as a mediator linking workplace loneliness to OCBs, especially for the female employees.
Transforming the German ICD-10 (ICD-10-GM) into Injury Severity Score (ISS)—Introducing a new method for automated re-coding

Background While potentially timesaving, there is no program to automatically transform diagnosis codes of the ICD-10 German modification (ICD-10-GM) into the injury severity score (ISS). Objective To develop a mapping method from ICD-10-GM into ICD-10 clinical modification (ICD-10-CM) to calculate the abbreviated injury scale (AIS) and ISS of each patient using the ICDPIC-R and to compare the manually and automatically calculated scores. Methods Between January 2019 and June 2021, the most severe AIS of each body region and the ISS were manually calculated using medical documentation and radiology reports of all major trauma patients of a German level I trauma centre. The ICD-10-GM codes of these patients were exported from the electronic medical data system SAP, and a Java program was written to transform these into ICD-10-CM codes. Afterwards, the ICDPIC-R was used to automatically generate the most severe AIS of each body region and the ISS. The automatically and manually determined ISS and AIS scores were then tested for equivalence. Results Statistical analysis revealed that the manually and automatically calculated ISS were significantly equivalent over the entire patient cohort. Further sub-group analysis, however, showed that equivalence could only be demonstrated for patients with an ISS between 16 and 24. Likewise, the highest AIS scores of each body region were not equal in the manually and automatically calculated group. Conclusion Though achieving mapping results highly comparable to previous mapping methods of ICD-10-CM diagnosis codes, it is not unrestrictedly possible to automatically calculate the AIS and ISS using ICD-10-GM codes.
