The Evident Need for Banking Reform in the Legal Marijuana Industry
Authors: James Jonathan T. , Tippins Steven C.
Published: August 2021

Marijuana reform legislation has created a lucrative industry for legal marijuana on the local and state level in some jurisdictions. Federal laws have forced legal marijuana dispensaries to be cash-only businesses with limited banking options. The lack of normal banking services has also affected firms’ ability to manage profits earned from operations. Our hermeneutic phenomenological study was grounded by the conceptual framework of the motivations of humans and humans’ need to feel safe. The participants in this study were owners and operators in the legal marijuana industry in Colorado. Data were collected through interviews, although the Coronavirus (COVID-19) pandemic of 2020 made data collection more challenging because of the added pressure on potential participants. The data analysis plan for this study consisted of transcribing and reviewing the data, coding themes and supporting themes, and synthesizing and reporting findings from the data collected. The study’s findings included the participants’ concerns about safety in their cash-only operations, their methods for conducting business, and the banking options available to them. Common themes that emerged from the interviews were cash, banking, safety, and the limitations of business size. Findings from my study contribute to fostering positive social change on the organization and industry level by providing accounts of how owners and operators navigate the banking dilemma in the legal marijuana industry.
An Interdisciplinary Rendezvous Between Mathematics and Literature: Reflections on Beauty as a Perspective in Comparative Disciplinary Didactics and a Thematic Approach to Interdisciplinary Work in Upper Secondary School
Authors: Jankvist Uffe , Rørbech Helle , Bremholm Jesper
Published: August 2021

n this paper we propose a thematic focus on aesthetics in the context of an interdisciplinary collaboration between mathematics and literature (Language Arts) as a way to further students’ reflections on and deeper understanding of what characterizes the two subjects. Furthermore, we argue that approaching aesthetics through the perspective of literacy can potentially strengthen students’ understanding of ways of thinking particular to specific (academic) disciplines; ways of thinking that are otherwise often hidden when teaching focuses on more pragmatic aspects. G. H. Hardy’s A Mathematician’s Apology from 1940 serves as the recurring illustrative example in our discussions of the pedagogical potentials of an interdisciplinary rendezvous between mathematics and literature.
Markov Chains for Computer Music Generation
Authors: Shapiro Ilana , Huber Mark
Published: August 2021

Random generation of music goes back at least to the 1700s with the introduction of Musical Dice Games. More recently, Markov chain models have been used as a way of extracting information from a piece of music and generating new music. We explain this approach and give Python code for using it to first draw out a model of the music and then create new music with that model.
Leonardo da Vinci in Raphael's School of Athens
Authors: Larsen Frode
Published: August 2021

At the center of the School of Athens, Raphael painted Plato with a face similar to that of Leonardo da Vinci. In this article I argue that the likeness was intentional, and that Raphael’s fresco contains a set of references to the book De Divina Proportione, to which Leonardo contributed with drawings of polyhedrons. De Divina Proportione was written by Leonardo’s friend and teacher of mathematics, Luca Pacioli, and contains arguments for raising the status of the art of painting, similar to the arguments found in Leonardo’s Paragone. Pacioli and Leonardo thought painting should be regarded as a liberal art, due to the painters' use of mathematical principles. In the article, I show how Plato with the face of Leonardo is part of a set of allusions to these arguments found in The School of Athens.
Military Systems of Justice
Authors: Crosbie Thomas , Kleykamp Meredith
Published: August 2021

Sociologists have largely ignored the study of military tribunals and justice systems. We offer a descriptive overview of military systems of justice intended for use by political and military sociologists, focusing on the case of the United States armed services. We contextualize the principal military systems of justice and provide extended discussions of how the American case connects through formal and informal channels to international legal structures. American military law and justice link three key legal realms: international law on conflict and security at the global level; the so called National Security Constitution at the national level; and the Uniform Code of Military Justice at the institutional level.
Representations of British Armed Forces Veterans in the Press
Authors: Phillips Rita , Connelly Vince , Burgess Mark
Published: August 2021

Previous research has shown that British public perception of veterans can be negative and erroneous. Surveys, for example, indicate that veterans are characterized as skilled and valorous individuals but also as suffering from ill-health, unemployment, and homelessness. To investigate how these beliefs may form, the present study examines the public dimension of knowledge by analyzing depictions of veterans in the media. A total of 335 newspaper articles that represent British veterans were downloaded from Google News and UKPressonline. After the articles were classified with a content analysis, chi-square tests were conducted to understand how the representation of veteransmay be related to the political affiliations of news agencies and by newspaper format. The results suggest that British veterans are predominantly represented in both heroic and victimizing contexts. While political affiliation did not affect the representation of veterans significantly, newspaper format did, with broadsheet (quality) newspapers emphasizing victimized contexts and local and international newspapers focusing on heroic contexts, with tabloids occupying a middle ground. In conclusion, broadsheet newspapers may express sociocultural scrutiny toward the ways in which veterans are treated, while local and international newspapers may focus on stereotypical representations of heroic British military actions that veterans may symbolize. Implications and conclusions are discussed.
On Loss, Gain, Acceptance and Belonging: Spanish in the Midwest
Authors: Foulis Elena , Alex Stacey
Published: August 2021

In this article, the authors analyze the creation of a performance piece in both English and Spanish with undergraduate students to creatively combine Latina/o/x oral histories and performance artists’ personal experiences as Spanish speakers. Each performer selected an oral history collected by one of the authors in the digital and publicly available archive, Oral Narratives of Latin@s in Ohio. Through a Latino Critical Race Theory framework, and an analysis of the undergraduate student performers’ and audience’s reactions, the authors demonstrate how this kind of performance can be used as a pedagogical tool to strengthen Spanish as a heritage language learners’ sense of belonging in predominantly white educational spaces  by contesting epistemic violence and forging Latina/o/x networks of solidarity. Linguistic and cultural maintenance in the face of racialization is conceptualized as a tool for place-making and social justice, particularly in the Midwestern communities that have experienced backlash to growing Latino presence. The performance provides a model for future artistic work that harnesses the power of community cultural wealth as conceptualized by education and Latina/o studies scholar Tara Yosso (2005). Crucially, rather than insist on cultural and linguistic conformity for the sake of social and political unity, this work critically attends to the diversity among Latina/o/x experiences represented across the performance.
Unacceptable Agency
Authors: Bendik-Keymer Jeremy ,   International Association for Environmental Philosophy
Published: August 2021

The Earth System Governance Project is the largest scholarly body in the world devoted to articulating governance of the Earth’s systems. It recently published a “Harvesting Initiative” looking back on the first iteration of its Scientific Plan. This paper contributes to the decolonial and constructive critique of the theory of agency in that Initiative and argues that it displays “fragmentary coloniality” especially around problematic authority relations in governance. By turning to work on “worlding,” the paper argues for radicalizing questions of authority, leading us to focus not on agency but on moral relationships—work for a sequel to this paper.

Context.—

In the face of the coronavirus disease 2019 (COVID-19) pandemic response, it was worthwhile to test the safety and efficacy of COVID-19 convalescent plasma (CCP) transfusion.

Objective.—

To establish a CCP donation program based on the availability of recovered COVID-19 patients and the practical limitations in recruiting clinically valid donors in a multicultural setting.

Design.—

From March to June 2020, we developed a program for collection of COVID-19 CCP as part of the treatment options for patients affected with COVID-19. From an initial population of 3746 candidates, only those with positive polymerase chain reaction results in at least 2 separate tests were considered. This filter reduced the eligible donor pool to 488 patients. After other exclusions were applied, such as language barrier, age, accessibility to donation, and comorbidities, the final count was 267 potentially eligible donors, which represented only 54.7% (267 of 488) of preselected candidates.

Results.—

Eighty donors were called. Approximately a third of the calls provided additional challenges as outlined by the following 4 reasons: limited functional understanding of English; schedule availability due to rotating work timetables; transportation restrictions since public transport services were severely restricted during lockdown; and lost to follow-up. Finally, a total of 38 valid donors participated, upon whom 45 apheresis procedures were performed.

Conclusions.—

As a summary of our experience, we can conclude that despite the limitations we were able to establish an effective program. A total of 90 units of CCP were collected before the pandemic curve began to flatten toward the end of June 2020.
Participation Reports help Crossref members drive research further
Authors: Tolwinska Anna
Published: August 2021

This article aims to explain the key metadata elements listed in Participation Reports, why it’s important to check them regularly, and how Crossref members can improve their scores. Crossref members register a lot of metadata in Crossref. That metadata is machine-readable, standardized, and then shared across discovery services and author tools. This is important because richer metadata makes content more discoverable and useful to the scholarly community. It’s not always easy to know what metadata Crossref members register in Crossref. This is why Crossref created an easy-to-use tool called Participation Reports to show editors, and researchers the key metadata elements Crossref members register to make their content more useful. The key metadata elements include references and whether they are set to open, ORCID iDs, funding information, Crossmark metadata, licenses, full-text URLs for text-mining, and Similarity Check indexing, as well as abstracts. ROR IDs (Research Organization Registry Identifiers), that identify institutions will be added in the future. This data was always available through the Crossref ’s REST API (Representational State Transfer Application Programming Interface) but is now visualized in Participation Reports. To improve scores, editors should encourage authors to submit ORCIDs in their manuscripts and publishers should register as much metadata as possible to help drive research further.

Simulation Model for Cooling Panels with Integrated Latent Thermal Storage System
Authors:   , Millers Renārs
Published: August 2021

This Thesis focuses on the development of an experimentally validated equation based simulation model of a cooling panel with integrated latent thermal storage system for utilization in Nearly Zero-Energy Buildings (NZEB) buildings. Development of such model is necessary in order for this technology to achieve industry-readiness. The Thesis is composed of a literature review and an experimental study. The literature review focuses on NZEB requirements in the European Union (EU) member countries, previous research in the field of passive cooling technologies and latent thermal storage systems. The passive cooling technologies described in the literature review are considered potential cooling energy sources to be coupled with the researched cooling panel. A combination of these technologies may be used to address overheating issues in NZEB buildings. The experimental study is focused on the development and validation of the aforementioned cooling panel simulation model. The numerical model is developed by using dynamic simulation software IDA ICE and is composed of sub-models written in Neutral Model Format (NMF). The simulation model is validated against experimental measurements carried out in a test chamber that was developed specially for this study. Moreover, a comparative study is carried out where the results generated by the developed and validated simulation model are compared against a previous CFD simulation study results acquired by a different research team. The accuracy of the results generated by the simulation model when compared with experimental measurements is a maximum deviation of 2.2 °C and a root mean square error of 1.01 °C. The results indicate that the accuracy reached by the simulation model is equal or higher than reported in other similar studies, therefore the accuracy is considered suitable for energy, thermal comfort and cooling load simulation in whole building scale simulation studies. The experimental study also provides several limitations for the proposed simulation model that shall be respected in order to reach the accuracy claimed in this study.

Flexible electronics technology plays an important role in regulating the properties of semiconducting materials, leading to the breakthrough in traditional strain engineering that is limited by the rigid and brittle inorganic materials and the fixed strain values. Thereby, the relevant research not only provides a new clue for strain regulation of semiconductor materials or other functional materials, but also lays a theoretical foundation for the performance evaluation of stretchable and flexible electronic devices based on inorganic functional materials in large-deformation environments. In this paper, the research progress of flexible inorganic electronics and strain effects on band structures, especially the property regulation of semiconducting materials in flexible electronics, is reviewed. Firstly, the nano-diamond particles based thinning process and the transfer printing are emphatically expounded with their influence on the properties of semiconducting electronics explored. In addition, the development and application of strain effect on band structure in recent years are introduced. In particular, the strain control based on buckling GaAs nanoribbon and buckling quantum well structure are studied to demonstrate the superior advantage of flexible electronics technology in the property regulation of semiconducting materials. The application and developing trend of strain engineering in the future are prospected finally.
Multi-syndrome, multi-gene risk modeling for individuals with a family history of cancer with the novel R package PanelPRO
Authors: Lee Gavin , Liang Jane W , Zhang Qing , Huang Theodore , Choirat Christine , Parmigiani Giovanni , Braun Danielle
Published: August 2021

Identifying individuals who are at high risk of cancer due to inherited germline mutations is critical for effective implementation of personalized prevention strategies. Most existing models focus on a few specific syndromes; however, recent evidence from multi-gene panel testing shows that many syndromes are overlapping, motivating the development of models that incorporate family history on several cancers and predict mutations for a comprehensive panel of genes.

We present PanelPRO, a new, open-source R package providing a fast, flexible back-end for multi-gene, multi-cancer risk modeling with pedigree data. It includes a customizable database with default parameter values estimated from published studies and allows users to select any combinations of genes and cancers for their models, including well-established single syndrome BayesMendel models (BRCAPRO and MMRPRO). This leads to more accurate risk predictions and ultimately has a high impact on prevention strategies for cancer and clinical decision making. The package is available for download for research purposes at https://projects.iq.harvard.edu/bayesmendel/panelpro.

This study aims at classifying flat ground tricks, namely Ollie, Kickflip, Shove-it, Nollie and Frontside 180, through the identification of significant input image transformation on different transfer learning models with optimized Support Vector Machine (SVM) classifier. A total of six amateur skateboarders (20 ± 7 years of age with at least 5.0 years of experience) executed five tricks for each type of trick repeatedly on a customized ORY skateboard (IMU sensor fused) on a cemented ground. From the IMU data, a total of six raw signals extracted. A total of two input image type, namely raw data (RAW) and Continous Wavelet Transform (CWT), as well as six transfer learning models from three different families along with grid-searched optimized SVM, were investigated towards its efficacy in classifying the skateboarding tricks. It was shown from the study that RAW and CWT input images on MobileNet, MobileNetV2 and ResNet101 transfer learning models demonstrated the best test accuracy at 100% on the test dataset. Nonetheless, by evaluating the computational time amongst the best models, it was established that the CWT-MobileNet-Optimized SVM pipeline was found to be the best. It could be concluded that the proposed method is able to facilitate the judges as well as coaches in identifying skateboarding tricks execution.

Published: August 2021

Hydroelectric dams represent an emergent threat to lowland tropical forest biodiversity. Despite the large number of operational, under-construction, and planned hydroelectric dams, their long-term effects on biodiversity loss are still poorly documented. Here, we investigate avian extinctions resulting from the Tucuruí Hydroelectric Reservoir (THR), the oldest Amazonian mega dam, which impounded the Tocantins River in 1984. Our avian inventory—based on several sampling methods (mist-netting, point-counts, boat census and qualitative surveys) during 280 days of fieldwork from 2005 to 2007—was combined with an exhaustive search of museum vouchers and digital online databases of citizen science from the lower Tocantins River to identify long-term trends in species persistence and extinction in the THR influence area. The regional avifauna was comprised of 479 species, 404 of which were recorded during our fieldwork. Based on recent and historical records spanning 172 years, we found evidence for likely extinctions at THR influence area for 53 (11.06%) species that have remained entirely unreported since 1984. We were further able to estimate extinction probabilities for 20 species; 15 species were considered to be extinct, includingPsophia interjectaandPyrilia vulturinathat are red-listed by IUCN. Our study serves as a baseline for avifaunal monitoring in the THR influence area and shows that degree of habitat specialization is a key factor in determining species extinctions caused by nonrandom habitat loss from either inundation or deforestation. Avian species extinctions will most likely continue across the area affected by the reservoir as a direct impact of alluvial forest loss and ongoing habitat degradation of upland forests.

Industry 4.0
Authors: Demoly Frédéric , André Jean‐Claude
Published: August 2021

The Industry 4.0 concept corresponds to a new way of organizing the means of production. It refers to the generation of connected, robotized, and intelligent factories. With the digital revolution, the boundaries between the physical and digital worlds are shrinking to merge with new interactive modes between operators, machines, and products. Artificial intelligence, 3D printing, virtual reality, digital twin, blockchain, robotics, and digital technologies are transforming the means of production, organization, and business models of companies. If it is a more competitive technological revolution, bearer of numerous innovations, and creator of a new market dynamic, of possible reintegration of manufacturing in Western countries, Industry 4.0 disrupts the world of work as a whole. Indeed, it is the whole system of decision and political regulation of companies, communities, and states (and their natures) of the work relations on the part of the operators which is questioned with an obligation to get out of the processes of individualization and social misanthropy which are taking place at the moment. Transitions are therefore taking place with the search for a possible combination of classical aspects with the immense potential of digital technologies.
Multipronged Fabrication of Co3Se4 Wrapped into N‐Doped Multiwall Carbon Nanotubes Tangled Hollow Dodecahedron Framework for Overall Water Splitting under Benign Condition
Authors: Yang Xiao , Chen Tao , Liu Li , Fu Wensheng
Published: August 2021

In this work, a synergistic strategy is proposed to synthesize a high‐performance bifunctional electrocatalyst (marked as Co3Se4/N‐CNTs) for neutral water splitting, in which Co3Se4 nanoparticles are wrapped into N‐doped multiwall carbon nanotubes assembled hollow dodecahedron framework. The neutral‐oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) catalytic performances of Co3Se4/N‐CNTs are maximally optimized by regulating nanostructure engineering, element doping, and carbon coating. In 1 m phosphate buffer solution (PBS) electrolyte, Co3Se4/N‐CNTs catalyst exhibits superior stability and catalytic activity for OER and HER, yielding a geometrical catalytic current density of 10 and −10 mA cm−2 at rather low overpotentials of 385 and 102 mV, respectively, meanwhile operating continuously for 35 h without obvious polarization increase. It is worth mentioning here, when a neutral electrolyzer is assembled, Co3Se4/N‐CNTs‖ Co3Se4/N‐CNTs cell contributes a high performance for overall water splitting in 1 m PBS electrolyte, delivering a current density of 10 mA cm−2 at a low applied external potential of 1.75 V, and displaying satisfying operation stability without evident deactivation after 35 h. The catalytic performances rival those of catalysts operated under moderate conditions. Consequently, all the merits promise that Co3Se4/N‐CNTs is an attractive bifunctional catalyst for hydrogen fuel production and storage of intermittent renewable energy sources under environmentally friendly conditions.
How women saved agricultural economics
Authors: Offutt Susan , McCluskey Jill
Published: August 2021

Women entered agricultural economics in numbers starting in the 1980s, and their ranks are increasing over time. We make the case that women have increased the relevance in the field of agricultural economics through their diverse interests, perspectives, and experiences. We document how women have changed the profession of agricultural economics in both academia and government. In research, women have expanded the field's treatment of non‐traditional topics such as food safety and nutrition and environmental and natural resource economics. In this sense, women saved the profession from a future as a specialty narrowly focused on agricultural production and markets.
Crop yield response functions in nutrient application: A review
Authors: Dhakal Chandra , Lange Kelly
Published: August 2021

The question of the optimal nutrient application in agricultural production continues to gather attention because of its relevance in increasing the profitability of crop production and protecting the environment. Economically optimal nutrient application decision rules are commonly derived by fitting crop yield functions to nutrients. The choice of the appropriate yield functional form thus is critical for estimating unbiased and more precise nutrient recommendations. This review explores recent developments in yield response functions to the nutrient application. We first introduce the concept of the economic theory of production and yield response functions. We then explain, with mathematical equations, some commonly used functional forms: quadratic response, Mitscherlich–Baule, deterministic, and stochastic plateau functions. We also summarize the strengths and weaknesses of each functional form and its implications for nutrient management strategies from an economic perspective. In recent studies, researchers have suggested that stochastic plateau functional forms, both linear and quadratic, could explain yield response to the nutrient application in a better way. Finally, we recommend fitting stochastic plateau functions in conjunction with carryover information in a dynamic optimization setting may yield more accurate optimal nutrient levels. Future research should continue to investigate whether these functional forms perform better in different crop and soil environments.

Sotos syndrome is characterized by overgrowth starting before birth through childhood with intellectual disability and craniofacial anomalies. The majority of patients are large for gestational age with developmental delay or intellectual disability. The majority of cases are caused by pathogenic variants in NSD1. The most consistent physical features in this disorder are facial dysmorphisms including prominent forehead, downslanted palpebral fissures, prognathism with a pointed chin, and a long and narrow face. We present a follow‐up to a cohort of 11 individuals found to harbor heterozygous, pathogenic, or likely pathogenic variants in NSD1. We analyzed the facial dysmorphisms and the condition using retrospective over 20 years. Among these patients, followed in our medical genetics outpatient clinic for variable periods of time, all had a phenotype compatible with the characteristic Sotos syndrome facial features, which evolved with time and became superimposed with natural aging modifications. We present here a long‐term follow‐up of facial features of Brazilian patients with molecularly confirmed Sotos syndrome. In this largest Brazilian cohort of molecularly confirmed patients with Sotos syndrome to date, we provide a careful description of the facial phenotype, which becomes less pronounced with aging and possibly more difficult to recognize in adults. These results may have broad clinical implications for diagnosis and add to the global clinical delineation of this condition.
High‐performance thin‐layer chromatography based approach for bioassay and ATR–FTIR spectroscopy for the evaluation of antioxidant compounds from Asparagus racemosus Willd. aerial parts

Published: August 2021

Asparagus racemosus Willd. is widely used to combat various diseases owing to its medicinal properties. In this study, arial parts of A. racemosus were investigated for their total phenolic content, total flavonoid content and antioxidative potential. A high‐performance thin‐layer chromatography (HPTLC) method combined with effect‐directed‐analysis was also developed to screen the antioxidant effects of A. racemosus and quantify biologically active compounds on chromatograms from A. racemosus. Total phenolics (154 mg gallic acid equivalent/g), flavonoid contents (497 mg quercetin/g) and IC50 (15.25 μg/ml) were found to be higher in methanolic extract of A. racemosus than in n‐hexane, chloroform and ethyl acetate extracts. HPTLC hyphenated with chemical derivatizations (DPPH•, p‐anisaldehyde/sulfuric acid, and ferric chloride) was used to evaluate antioxidant activity and the presence of phytosterols, terpenoids and polyphenolic contents. The same compounds at 100*retention factor = 58, 68, 74 and 65 in extracts were responsible for antioxidant activity. Hyphenated HPTLC allowed a rapid characterization of the active compound with a combination of effect‐directed‐analysis and attenuated total reflectance–Fourier transform infrared spectroscopy. Spectral analysis of the band from attenuated total reflectance identified myricetin, quercetin, p‐coumaric acid and caffeic acid as responsible for the antioxidant activity.
Phase I study of dose‐escalated stereotactic body radiation therapy for locally advanced pancreatic head cancers: Initial clinical results
Authors: Qing Shuiwang , Gu Lei , Zhang Huojun
Published: August 2021

Purpose

To establish the maximum tolerated dose (MTD) of stereotactic body radiation therapy (SBRT) for locally advanced pancreatic head cancers.

Methods

A total of 16 patients were included in the single‐institution phase I dose‐escalation study. The initial dose level was 35 Gy in five fractions, doses were then sequentially escalated to 37.5 Gy, 40 Gy, 42.5 Gy, and 45 Gy. The dose‐limiting toxicity (DLT) was defined as III/IV GI (gastrointestinal) toxicity.

Results

A total of 16 patients with locally advanced pancreatic head cancers were analyzed, 14 patients had received gemcitabine or S1‐based chemotherapy. Median OS and LPFS were 14.5 months and 12.5 months, respectively; The OS rates at 1 and 2 years were 68.8% and 25%, respectively. No grade 3 or 4 acute or late GI toxicities were observed. Grade 3 toxicities were observed in four patients with three hematologic toxicities and one biliary obstruction for acute toxicities, G1–2 of GI late toxicity were in 31.25% of patients.

Conclusions

SBRT doses ranging from 35 to 45 Gy in five fractions could be given for patients with locally advanced pancreatic head cancers without severe GI toxicities, whereas the side effect of biliary obstruction should be paid more attention.

Equilibrium Analyses and Kinetics of Carbon Dioxide Methanation Using an Alumina‐Supported Ruthenium Catalyst
Authors: Uysal Duygu
Published: August 2021

With CO2 being accepted as the main cause of the climate change, considerable efforts currently focus on capturing CO2 from major point sources and to store it. Another, better way is to utilize the captured CO2 to produce useful fuels like methane. The Sabatier reaction was studied in this work, using 0.5 % ruthenium on alumina as catalyst. A quartz reactor packed with catalyst particles and placed in a vertical furnace was employed. A stoichiometric ratio of CO2/H2 was used and the temperature was changed between 150 and 400 °C, while the flow rate of the feed gas mixture was varied between 250 and 625 mL min−1, with different amounts of catalyst. The temperature was identified as the major parameter affecting the conversion. Carbon dioxide conversions greater than 85 % were obtained at temperatures higher than 350 °C.
Shortcut Method for Initialization of Dividing‐Wall Columns and Estimating Pareto‐Optimal NQ‐Curves
Authors: Ränger Lena-Marie , Grützner Thomas
Published: August 2021

In early project stages, often no simulation results are available for dividing‐wall columns. Hence, shortcut methods are used to estimate suitable vapor and liquid splits. In a previous paper, it was demonstrated that diagrams are a suited tool to satisfy this need. However, it has turned out that it shows weaknesses for columns with finite or non‐optimal stages. This contribution closes that gap and presents an extended approach to derive suited initial guesses. For this purpose, the original diagram is combined with a heuristic approach to calculate Pareto‐optimal column designs resulting in a stage‐adapted diagram. A comparative study illustrates that the new approach is a powerful tool to generate reliable guesses for multiple dividing‐wall column simulations with finite stage numbers.

Prussian blue analogue Na2Ni[Fe(CN)6] (Ni–PB) has been widely studied as a cathode material for sodium‐ion battery due to its excellent cycling performance. However, Ni–PB has a low theoretical capacity of 85 mAh g−1 because of the electrochemical inertness of Ni. Herein, ternary Ni–PB is successfully synthesized by double doping with Co and Fe at Ni‐site, and the effect of doping with Co and Fe on the electrochemical performance of Ni–PB is systematically investigated through theoretical calculations and electrochemical tests. The first principles calculations confirm that double doping with Co and Fe can significantly reduce the energy barrier and bandgap of Ni–PB. X‐ray diffraction and composition analysis results indicate that ternary NiCoFe–PB composite not only has good crystallinity and high Na content but also has low defects and crystal water. Electrochemical tests reveal that, besides the capacity contribution of high‐spin Co/Fe and low‐spin Fe, Co‐doping enhances the electrochemical activity of low‐spin Fe and Fe‐doping improves the activity of high‐spin Co; moreover, double doping can decrease the diffusion resistance of Na+ ions through solid electrolyte interface film, accelerate the kinetics for both ion diffusion process and Faradic reaction, and increase active sites. Under the synergistic effect of Co and Fe, this ternary NiCoFe–PB exhibits outstanding electrochemical performance with a high initial discharge capacity of 120.4 mAh g−1 at 20 mA g−1 and an extremely low capacity fading rate of 0.0044% per cycle at a high current density of 2 A g−1 even after 10,000 cycles, showing great application potential of ternary NiCoFe–PB in the field of large‐scale energy storage.

Conjugated molecules and polymers with intrinsic quinoidal structure are promising n‐type organic semiconductors, which have been reported for application in field‐effect transistors and thermoelectric devices. In principle, the molecular and electronic characteristics of quinoidal polymers can also enable their application in organic solar cells. Herein, two quinoidal polymers, named PzDP‐T and PzDP‐ffT, based on dipyrrolopyrazinedione were synthesized and used as electron acceptors in all‐polymer solar cells (all‐PSCs). Both PzDP‐T and PzDP‐ffT showed suitable energy levels and wide light absorption range that extended to the near‐infrared region. When combined with the polymer donor PBDB‐T, the resulting all‐PSCs based on PzDP‐T and PzDP‐ffT exhibited a power conversion efficiency (PCE) of 1.33 and 2.37 %, respectively. This is the first report on the application of intrinsic quinoidal conjugated polymers in all‐PSCs. The photovoltaic performance of the all‐PSCs was revealed to be mainly limited by the relatively poor and imbalanced charge transport, considerable charge recombination. Detailed investigations on the structure‐performance relationship suggested that synergistic optimization of light absorption, energy levels, and charge transport properties is needed to achieve more successful application of intrinsic quinoidal conjugated polymers in all‐PSCs.

The synthesis, characterization and photoluminescent properties of four cyclometalated (C N)‐type gold(III) complexes bearing a bidentate diacetylide ligand, tolan‐2,2’‐diacetylide (tda), are reported. The complexes exhibit highly tunable excited state properties and show photoluminescence (PL) across the entire visible spectrum from sky‐blue (λPL=493 nm) to red (λPL=675 nm) with absolute PL quantum yields (PLQY) of up to 75 % in solution, the highest PLQY found for any monocyclometalated Au(III) complex in solution. As a consequence of the use of the strongly rigidifying diacetylide bidentate ligand, a significant increase in the excited state lifetimes (τ0=16–258 μs) was found in solution and in thin films. The complexes showed remarkable singlet oxygen generation in aerated solution with absolute singlet oxygen quantum yield (ϕ1Δ) values reaching up to 7.5×10−5 and singlet oxygen lifetimes (τ01Δ) in the range of 66–95 μs. Furthermore, the radiative and non‐radiative rates of singlet oxygen were determined using the ϕ1Δ and τ01Δ values and correlations are drawn between the formation of singlet oxygen and its interaction with cyclometalated (C N) gold(III) complexes.

Background

Extant evidence links neighborhood walkability with obesity‐related health in the general population. This association likely exists in cancer survivors, but research is limited. Furthermore, a disproportionate obesity burden in African American cancer survivors warrants subgroup‐specific analyses.

Methods

This study analyzed data from 2089 African American cancer survivors participating in the Detroit Research on Cancer Survivors (ROCS) cohort. On the basis of built environment data summarized within 1‐km radial buffers around census block centroids, a multidimensional neighborhood walkability index (NWI) was constructed. Survivors' residential addresses at Detroit ROCS enrollment were geocoded, and addresses were linked to NWI scores via the census block of residence. At study enrollment, survivors reported height and weight; these data were used to calculate their body mass index (BMI). Associations between NWI quartiles and BMI overall and by cancer type, biological sex, and physical activity engagement were evaluated.

Results

BMI was found to be inversely associated with increasing NWI quartile (P for trend < .01). This inverse relationship was observed in men (P for trend < .01) and in survivors reporting any regular physical activity (P for trend < .01).

Conclusions

This study's findings suggest that among African American cancer survivors, higher neighborhood walkability is associated with lower BMI. As health care systems in the United States increasingly consider the role of the neighborhood environment in their patients' health, these findings provide additional evidence supporting health systems' incorporation of neighborhood walkability as an obesity‐related health indicator for this cancer survivor subgroup and potentially for cancer survivors from other vulnerable populations.
Construing colours using repertory grid technique: An idiographic approach in colour perception

Published: August 2021

This article offers an alternative methodological approach to the exploration of subjective experiences by studying individuals' personal views of perceived colours. The study aims to investigate the construals of individuals related to perceived colours using an idiographic approach. The subjective approach proposed is based on the theory of personal construct psychology and the methodology of the repertory grid technique. A repertory grid experiment was conducted to determine individuals' ways of construing colours and examine the collective understanding of the content and structure of individuals' construals concerning perceived colours. Sixty undergraduate students participated in the experiment, yielding 60 different repertory grids that included a number of personal constructs indicating the construal process of participants in differentiating between 11 basic colours. Participants produced their own semantic bipolar dimensions for comparing the perceived colours and creating differential ratings according to their personal constructs. The elicited data were evaluated using qualitative content analysis to understand the differences between individual systems of constructs and investigate the commonality of shared constructs relating to colours. The data were also analyzed quantitatively to investigate the common structure of and interrelationship between elicited constructs and perceived colours. The outcomes have the potential to contribute to academic and practical knowledge concerning colour perception, as well as encouraging further studies with an idiographic approach.
