Truly standard‐essential patents? A semantics‐based analysis
Authors: Brachtendorf Lorenz , Gaessler Fabian , Harhoff Dietmar 
Published: September 2022

AbstractStandard‐essential patents (SEPs) have become a key element of technical coordination via standard‐setting organizations. Yet, in many cases, it remains unclear whether a declared SEP is truly standard‐essential. To date, there is no automated procedure that allows for a scalable and objective assessment of SEP status. This paper introduces a semantics‐based method for approximating the standard essentiality of patents. We provide details on the procedure that generates the measure of standard essentiality and present the results of several validation and robustness exercises. We illustrate the measure's usefulness in estimating the share of true SEPs in firm patent portfolios for several telecommunication standards.

AbstractObjectiveTo evaluate the cleaning potential of 95% ethanol, acetone, and amyl acetate solutions used solely or in association, to remove epoxy resin‐based sealer residues from pulp chamber dentin and their microstructural effects.Materials and MethodsOne hundred and eighty bovine incisor specimens were divided into nine groups according to the cleaning protocol: ET (ethanol); AC (acetone); AA (amyl acetate); E1: AA+AC; E2: AA+ET; E3: AC+ET; E4: AA+AC+ET; PC (positive control), and NC (negative control). All groups were impregnated with epoxy resin‐sealer, except NC. Ninety specimens were divided into groups (n = 10) for evaluation of persistence of residues and amount of open dentinal tubules by SEM analysis and evaluation of chemical compounds on the dentin surface after cleaning with electron dispersive spectroscopy. The others 90 specimens were submitted to Knoop microhardness evaluation. Persistence of residues data were submitted to the Kruskal Wallis and Dunn tests (α = 0.05). Open dentinal tubules and microhardness data were submitted to one‐way ANOVA and Mann Whitney tests (α = 0.05).ResultsAA and E4 protocols showed the lowest persistence of residues. E4 group had the highest incidence of open dentinal tubules. E3 and E4 groups showed no changes in the atomic ratio Ca/P, which was similar to NC group. E4 group did not present W, an element presents in all the other groups. ET and E4 protocols showed the smallest reduction in dentin microhardness.ConclusionsThe combination of amyl acetate, acetone and ethanol is the most effective and safe protocol to remove epoxy sealer residues on pulp chamber dentin. Moreover, it has the lowest microhardness reduction.Clinical SignificanceThe combined use of amyl acetate, acetone, and ethanol enhanced the cleaning of pulp chamber dentin with minimal microstructural damage.
In vitro analysis of antioxidant peptides from an enzymatically hydrolysed Channa punctata protein isolate
Authors: Das Madhushrita , Ghosh Mahua 
Published: September 2022

AbstractChanna punctata, a freshwater fish consists of a good amount of protein (64.42 ± 0.51%) with essential amino acids. The degree of hydrolysis was maximum at 240 min with 82.72 ± 0.89% and 21.37 ± 1.21% of hydrolysis in the case of Alcalase 2.4 L (AlcHyd240) and pepsin (PepHyd240). Low molecular weight bands (<10 kDa) were more prominent in AlcHyd240. Hydrolysate shows improved functional properties in comparison with isolate. <3 kDa ultrafiltrate shows enhanced antioxidative efficacy than the hydrolysate and isolate. The fractions were analysed by MALDI‐TOF MS/MS and two peptides PLRVGN and PLPNSK with the highest score of 70.4 and 56.5, respectively and hydrophobicity of 50% were selected for in vitro study. Molecular docking studies revealed that peptides interacted with the radicals by H‐bond. The presence of proline, leucine, valine, glycine, arginine, serine, and lysine induces antioxidant activity. Thus, this study suggested the peptides identified from Channa punctata can be used as a nutraceutical with potent antioxidant activity.Novelty impact statement

A potent antioxidant Channa punctata protein hydrolysates were generated by enzymatic hydrolysis and were purified by ultrafiltration.

Amino acid sequences PLRVGN and PLPNSK were identified by using MALDI‐TOF MS/MS. Docking study revealed H‐bond interactions between the peptides and the free radical.

According to the structure–activity relationship study, the presence of hydrophobic amino acid residues, glycine, and serine influences the antioxidant potential.
The Effect of Monetary Policy on Consumption Inequality: An Analysis of Transmission Channels through TANK Models
Authors: KOMATSU MOMO 
Published: September 2022

AbstractWhat transmission channels drive the effect of monetary policy on consumption inequality? This paper investigates this question with tractable Two‐Agent New Keynesian models with search‐and‐matching frictions and wage rigidities. I make a distinction between credit‐constrained households and unconstrained households and find that an expansionary monetary policy shock decreases consumption inequality between those two households through three channels: (i) the income composition channel, through fluctuations in labor and profit income; (ii) the savings redistribution channel, through fluctuations in real interest rate; and (iii) the earnings heterogeneity channel, through fluctuations in unemployment. The results are in line with the empirical evidence.

Published: September 2022

AbstractBackgroundBased on the big data of 2010, 2011, and 2012, when H1N1 influenza was prevalent around the world in the past, this study investigated the obesity rate, weight change, and dietary methods of Korean dieters based on the historical situation of the past H1N1 influenza epidemic in Republic of Korea. This is intended to be the data for utilizing the prognostic evaluation of coronavirus disease‐19 (COVID‐19).ObjectiveAfter COVID‐19, research on obesity should be conducted systematically, and to prevent obesity, nutrition education, customized inner beauty & cosmetics, and the development of body slimming cream and leptin for proper diet should be done at the national level. This study was conducted to investigate the relationship between methods of weight control, generation, and gender, which have not yet been evaluated in the Korean adult population.MethodsThe cross‐sectional study was comprised of 25 534 Korean who participated in the Fifth Korean National Health and Nutrition Examination Survey (KNHNES) conducted in 2010, 2011, and 2012.ResultsA 17 876 of the 19 375 respondents 20 years of age or older in the KNHNES answered about diet method. Two thousand and fifty‐seven (15.63%) men and 4134 (25.77%) women thought of themselves as fat. However, 11 973 people (66.96%) did not change weight in the past year, 2536 people (14.19%) had increase in weight, and 3.164 (17.70%) reduced weight. A total of 7176 people (48.11%) indicated that they attempted to reduce weight through exercising, while 5553 people (37.23%) did so through reduced food intake.ConclusionsThis study was based on big data at the time of the H1N1 influenza epidemic in Korean population. The results of the present study will be helpful in the development of the body slimming cream and leptin via direct to consumer (DTC) gene test (GT) due to the rapid increase in obesity due to COVID‐19 pandemic.

Authors: Dow Dawn M. , Few‐Demo April L. , Williams Deadric T. 
Published: September 2022

AbstractThis introductory essay situates this special issue within the context of antiracism and social justice for family scholars. The editors underscore the political and social context that led the National Council on Family Relations' three flagship journals—Journal of Family Theory & Review (JFTR), Family Relations (FR), and Journal of Marriage and Family (JMF) to collectively invite submissions for separate special issues on Transformative Family Scholarship: Theory, Practice, and Research at the Intersection of Families, Race, and Social Justice. This special issue focuses on scholarship using cutting‐edge theory, research, and practices to investigate racial injustice and confront white supremacy within the context of the family. The guest editors synthesize the dominant themes cross‐cutting the 13 articles, including parenting, racial stratification, health and economic well‐being, and racial identity. The guest editors explain how these articles contribute to a more robust analysis of structural racism within families. The introduction closes with an invitation to scholars doing scholarship using critical theoretical approaches to continue their efforts and consider the Journal of Marriage and Family as a potential publication outlet for their research.

Published: September 2022

AbstractBackgroundTo evaluate the association between cumulative body mass index (BMI) and long‐term BMI change with non‐alcoholic fatty liver disease (NAFLD).MethodsWe included 19 477 adult participants (12 556 men and 6921 women) from the Kailuan study from January 2006 to December 2013. Cumulative BMI was assessed using a quadratic mixed‐effects method by sex before the index year; then, the NAFLD outcome was followed till December 2019. The long‐term BMI change was calculated as the percentage change in average cumulative BMI from the baseline BMI.ResultsDuring a median follow‐up of 5.63 years, 6229 individuals developed incident NAFLD. Independent of baseline BMI, the NAFLD risk escalated with the cumulative BMI with adjusted hazard ratios (HRs) (95% confidence interval [CI]) of 1.60 (1.48–1.73) and 2.28 (2.06–2.53) for the intermediate tertile and the highest tertile (Ptrend <0.001). The association is amplified in women and the young. Compared to a stable weight (BMI change: −3% to 3%), NAFLD risk increased in the baseline BMI < 24 kg/m2 group with weight gain (BMI change: >3%) and decreased in BMI ≥24 kg/m2 group with weight loss (BMI change: <−3%) for men and women. However, we only observed a decreased NAFLD risk in men (HR: 0.82, 95% CI: 0.69–0.97) with BMI < 24 kg/m2 and weight loss.ConclusionsMonitoring cumulative BMI may help to identify high‐risk NAFLD populations. The association between weight gain or loss varies by sex and baseline BMI, suggesting the importance of individualized weight management for NAFLD prevention.

AbstractAimTo describe adults with (non‐dialysis) chronic kidney disease (CKD) in nine public renal practice sites in the Australian state of Queensland.Methods7,060 persons were recruited to a CKD Registry in May 2011 and until start of kidney replacement therapy (KRT), death without KRT or June 2018, for a median period of 3.4 years.ResultsThe cohort comprised 7,060 persons, 52% males, with a median age of 68 yr; 85% had CKD stages 3A to 5, 45.4% were diabetic, 24.6% had diabetic nephropathy, and 51.7% were obese. Younger persons mostly had glomerulonephritis or genetic renal disease, while older persons mostly had diabetic nephropathy, renovascular disease and multiple diagnoses. Proportions of specific renal diagnoses varied >2‐fold across sites. Over the first year, eGFR fell in 24% but was stable or improved in 76%. Over follow up, 10% started KRT, at a median age of 62 yr, most with CKD stages 4 and 5 at consent, while 18.8% died without KRT, at a median age of 80 yr. Indigenous people were younger at consent and more often had diabetes and diabetic kidney disease and had higher incidence rates of KRT.ConclusionThe spectrum of characteristics in CKD patients in renal practices is much broader than represented by the minority who ultimately start KRT. Variation in CKD by causes, age, site and Indigenous status, the prevalence of obesity, relative stability of kidney function in many persons over the short term, and differences between those who KRT and die without KRT are all important to explore.
Singlet oxygen production by photosystem II is caused by misses of the oxygen evolving complex
Authors: Mattila Heta , Mishra Sujata , Tyystjärvi Taina , Tyystjärvi Esa 
Published: September 2022

Summary

Singlet oxygen (1O2) is a harmful species that functions also as a signaling molecule. In chloroplasts, 1O2 is produced via charge recombination reactions in photosystem II, but which recombination pathway(s) produce triplet Chl and 1O2 remains open. Furthermore, the role of 1O2 in photoinhibition is not clear.

We compared temperature dependences of 1O2 production, photoinhibition, and recombination pathways.

1O2 production by pumpkin thylakoids increased from −2 to +35°C, ruling out recombination of the primary charge pair as a main contributor. S2QA− or S2QB− recombination pathways, in turn, had too steep temperature dependences. Instead, the temperature dependence of 1O2 production matched that of misses (failures of the oxygen (O2) evolving complex to advance an S‐state). Photoinhibition in vitro and in vivo (also in Synechocystis), and in the presence or absence of O2, had the same temperature dependence, but ultraviolet (UV)‐radiation‐caused photoinhibition showed a weaker temperature response.

We suggest that the miss‐associated recombination of P680+QA− is the main producer of 1O2. Our results indicate three parallel photoinhibition mechanisms. The manganese mechanism dominates in UV radiation but also functions in white light. Mechanisms that depend on light absorption by Chls, having 1O2 or long‐lived P680+ as damaging agents, dominate in red light.
The Link between Internet Activity and Community Experience in Rural Utah☆
Authors: Muirbrook Kayci M. , Cope Michael R. , Sanders Scott R. 
Published: September 2022

AbstractThe growth of high‐speed Internet access in rural communities is a relatively recent event. In this exploratory study, we contribute to the literature regarding the Internet and local community by analyzing the influence of Internet activity on community experience, measured through community satisfaction and attachment, using the systemic model as controls. After surveying 24 rural communities in Utah, USA once in 2008 and again in 2017 with a cumulative analytic sample size of 2,236, we find a negative association between increased use of the Internet for amenity purposes and community experience. While our models show mixed findings that community experience has decreased over time in rural areas, we find evidence that Internet activities can affect community experience, strengthening arguments that researchers should control for more than merely Internet access. Due to the associations between Internet activities and community experience, we argue that rural policymakers should find place‐based ways to strengthen community experience.
Incorporating Contextual Factors Into Engineering Design Processes: An Analysis of Novice Practice
Authors: Burleson Grace , Herrera Sean V. S. , Toyama Kentaro , Sienko Kathleen H. 
Published: September 2022

Abstract
Incorporation of contextual factors into design processes is important for successful engineering design outcomes. Through document analysis and semi-structured interviews, we investigated the types of contextual factors incorporated by novice engineering designers and their approaches during design processes. Our findings demonstrated that participants primarily considered technical and institutional contextual factors across all design stages, informed largely by contextual observations and interviews with stakeholders. Socio-political contextual factors were less frequently considered. We also found that a broader set of contextual factors were incorporated when projects were set in unfamiliar contexts. And, contextual factors that could be easily quantified were more readily applied to design decisions. We suggest that there are opportunities for more intentional approaches to incorporating contextual factors throughout design processes.
The Numerical and Experimental Evaluation of a Coupled Blade Dynamic Limit Response With Friction Contacts
Authors: Grant Kelly , Gastaldi Chiara , Berruti Teresa M. , Kellerer Rudolf 
Published: September 2022

Abstract
Increasing demand for turbine power and efficiency requires larger and higher loaded turbine blades, which in turn requires the consideration of aeromechanical interactions. Whilst CFD tools can reliably predict stability using aerodynamic damping as an indicator, the component of mechanical damping also needs consideration. An understanding of the mechanical damping in the system becomes key to a robust blade design. Mechanical damping for such a part comes predominantly from friction occurring at the coupling contact faces. It is well established and published that such contact forces are nonlinear in relation to the relative movement at the contact interface. Moreover, contact area, the rigidity in the contact, friction coefficient, and normal contact force must also be considered and included as parameters that influence the result. Consequently, the level of system damping is not a constant and depends highly on the system response itself, as well as the other aforementioned parameters. In the case of self-excited vibrations such as flutter, the evaluation of the damped limit response is a part of the blade design process. A tool has been developed to numerically simulate contact friction forces with the intention of parametrically evaluating the limit response and relating this to the mechanical integrity of the part. This paper presents the modeling of a coupled blade system with friction contact forces, results coming from this evaluation, and a comparison with test data.
Bayesian Calibration of Kinetic Parameters in the CH Chemistry Toward Accurate Prompt-NO Modelling

Published: September 2022

Abstract
Significant efforts made by the gas turbine industry have helped reduce nitrogen oxides (NOx) emissions considerably. To meet and surpass the increasingly stringent regulations, accurate and robust thermochemical mechanisms are needed to help design future sub-10 ppm combustion systems. Uncertainty in kinetic modeling, however, can result in large prediction uncertainty and significant discrepancy between models that hinder the identification of promising combustors with confidence. Direct reaction rate measurements are seldom available for some reactions, especially when involving short-lived radicals such as methylidyne, CH. As the main precursor to the prompt-NO formation pathway, its large parametric uncertainty directly propagates through the nitrogen chemistry preventing accurate and precise emissions predictions. Recent independent CH concentration measurements obtained at various operating conditions are used as indirect rate measurements to perform statistical, or Bayesian, calibration. A subset of important reactions in the CH chemistry affecting peak-CH concentration is identified through uncertainty-weighted sensitivity analysis to first constrain the parametric space of this prompt-NO precursor. Spectral expansion provides the surrogate model used in the Markov-Chain Monte Carlo method to evaluate the posterior kinetic distribution. The resulting constrained CH-chemistry better captures experimental measurements while providing smaller prediction uncertainty of a similar order as the uncertainty of the measurements, which can increase the confidence in simulation results to identify promising future low-emissions configurations. For the quasi-steady-state species CH, fuel decomposition reactions leading to CH production are constrained while little impact is observed for intermediate reactions within the CH-chemistry. The reduction in prediction uncertainty results mainly from the constrained correlations between parameters which greatly limit the set of feasible reaction rate combinations. Additional independent direct and indirect measurements would be necessary to further constrain rate parameters in the CH chemistry, but this calibration demonstrates that predictions of radical species can be improved by assimilating enough data.
Computational Fluid Dynamics Investigation of a Novel Bi-Directional Axial Flow Turbine for Wave Energy Conversion

Published: September 2022

Abstract
Wave energy conversion devices incorporating the Oscillating Water Column (OWC) principle are the most extensively used wave energy converting technologies to date. In this paper, we explore the effect of a fixed blade Denniss-Auld turbine that is representative of the maximum pivot points which occur during OWC inhalation and exhalation. Whereas conventional Denniss-Auld turbines are mounted on an intricate hub system that allows for controlled blade rotation to optimize performance, we investigate the possibility of removing the mechanical complexity while maintaining good aerodynamic performance. The assessment of turbine performance is carried out using non-dimensional coefficients, i.e., torque, pressure drop, and efficiency. The simulations are completed by solving the incompressible, steady-state Reynolds Averaged Navier-Stokes (RANS) equations with the k-ω SST turbulence model using ANSYS™ CFX. Validation of our numerical approach was completed by comparing existing experimental and numerical data of a Wells turbine. Furthermore, a grid independence study was conducted to achieve accurate numerical results. Overall, the modified Denniss-Auld turbine does not stall at high flow coefficients and has an extended operating range similar to an impulse turbine; however, with a much lower maximum efficiency of 12%. Future work should explore a larger design space with blade optimization using parametric studies to improve device efficiency.
