Perceptual Motivation for Action
Authors: McClelland Tom , Jorba Marta
Published: January 2022

In this paper we focus on a kind of perceptual states that we call perceptual motivations, that is, perceptual experiences that plausibly motivate us to act, such as itching, perceptual salience and pain. Itching seems to motivate you to scratch, perceiving a stimulus as salient seems to motivate you to attend to it and feeling a pain in your hand seems to motivate actions such as withdrawing from the painful stimulus. Five main accounts of perceptual motivation are available: Descriptive, Conative, Imperativist, Reflexive and Dual Content views. Some of these have been developed in detail and others are natural extensions of existing views. However, we argue that none provides a satisfactory account of the target perceptual states. Driven by the failings of each account, we identify three conditions that any satisfactory theory of perceptual motivation must meet: Direct Motivational Force, Non-Obligatory Force and Intention-Independent Influence. Then we offer an account that attempts to fulfil these conditions: the Affordance Model. This model of perceptual motivation is premised on the claim that each of the target states involves the perception of a specific affordance for action and the triggering of Automatic Motor Initiations (AMIs). We suggest that AMIs can explain the motivational force of these perceptual states.

Published: January 2022

The lignocellulosic materials are promising feedstock to produce biofuels and bioproducts in the biorefinery framework. However, a pretreatment step is required to disrupt lignin-carbohydrate complex. In this work, the fractionation of Pinus radiata wood into its main components, cellulose-rich delignified solid, recovered lignin after precipitation, and soluble-in-black liquor hemicellulose, was studied. For this purpose, an organosolv process employing ethanol/water mixture as solvent in absence of a catalyst was carried out. The effects of operating conditions on delignified solid were evaluated by using a 23 central composite experimental design, being the responses delignified solid yield, delignification degree, hemicellulose content, and glucan content. The variables studied were temperature (170–200 °C), time (50–100 min), and ethanol concentration (40–60%). The increase of organosolv severity (temperature and time) and reduction of ethanol concentration favor the glucan enrichment of delignified solid, due to lignin removal and hemicellulose solubilization. A glucan content of more than 66% is obtained by applying temperature higher than 195 °C and time longer than 90 min, when 40 wt% alcohol concentration is used. The liquid fraction obtained during the organosolv process (black liquors) was used to recover lignin and hemicellulosic fractions solubilized. Furthermore, hemicellulose and lignin content of delignified solid was correlated with the thermal stability measured as T10%.
Towards a More Orderly Application of Proportionality to Patent Injunctions in the European Union
Authors: Sikorski Rafał
Published: January 2022

The intensity of IP protection has traditionally been determined by assessing the criteria that need to be satisfied for the protection to be granted, as well as the scope of rights and limitations of those rights. The enforcement stage and the remedies available to right holders have for long been, if not neglected, then certainly treated with lesser attention. The rise of aggressive litigation strategies, especially in the field of patents, has brought the enforcement stage to the forefront of the discussion about the proper level of IP protection in general and patent law in particular. Injunctions provide particularly strong leverage at the enforcement stage, allowing patentees in some cases to obtain royalties that exceed the value of the protected inventions. The principle of proportionality can play an important role as a check on excessive litigation strategies by patentees. Flexibility, however, comes at the price of uncertainty and unpredictability as to the outcome of patent disputes. Therefore, it is crucial to apply proportionality in an orderly and structured manner. For that purpose, the article identifies a set of factors that may be helpful in applying proportionality in patent disputes. That set of factors is well grounded in the traditions of the laws of the EU Member States.
Magnetic Coupler Robust Optimization Design for Electric Vehicle Wireless Charger Based on Improved Simulated Annealing Algorithm
Authors: Wang Zhenpo , Li Lantian , Deng Junjun , Zhang Baokun , Wang Shuo
Published: January 2022

Fleets of autonomous vehicles including shuttle buses, freight trucks, and road sweepers will be deployed in the Olympic Village during Beijing 2022 Winter Olympics. This requires intelligent charging infrastructure based on wireless power transfer technology to be equipped. To increase the misalignment tolerance of a high-power wireless charger, the robustness of the magnetic coupler should be optimized. This paper presents a new type of unipolar coupler, which is composed of three connected coils in series. The dimensional configuration of the coils is analyzed by the finite element method. The characteristic parameters of the coil are identified with their influence on the self-inductance and coupling coefficient. An expert model is built, whose feasibility can be verified in the aimed design domain. Combined with the expert model, an improved simulated annealing algorithm with a backtracking mechanism is proposed. The primary coil can reach the expected characteristics from any starting parameter combination through the proposed optimization algorithm. Under the same conditions in terms of external circuit parameters, ferrite usage, and aluminum shielding, the offset sensitivity of the magnetic coupler can be reduced from 58.79% to 18.89%. A prototype is established, validating the feasibility of the proposed coil structure with the optimized parameter algorithm.
Cardiometabolic Diseases and Female Sexual Dysfunction: Animal Studies
Authors: Angulo Javier , Hannan Johanna L.
Published: January 2022

Background

The association between erectile dysfunction and cardiometabolic disease is well characterized; men are often diagnosed with cardiovascular disease 2–5 years following the incidence of erectile dysfunction. There is evidence that this relationship may also exist for cardiometabolic diseases and female sexual dysfunction (FSD) – particularly sexual arousal disorders.

Aim

To provide a summary of the preclinical literature related to the evidence of FSD in animal models of cardiometabolic diseases and indicate where further research is needed.

Methods

A detailed Medline search of peer-reviewed publications was performed on the associations between animal models of cardiometabolic diseases, FSD and underlying mechanisms.

Outcomes

A summary of the preclinical evidence of FSD in animal models of cardiometabolic diseases.

Results

Common methods for assessing female sexual arousal and physiology in animal models include: 1) behavioral assessments (apomorphine-induced genital vasocongestive arousal; hormone-dependent lordosis), 2) nerve-mediated vaginal and clitoral blood flow, 3) pudendal artery, vaginal and clitoral smooth muscle physiology (vasoreactivity and molecular biology), 4) morphology of genital tissues. Twenty-eight studies examined female animal models of atherosclerosis, hypertension, diabetes (type 1 and 2) and obesity. They showed functional alterations, including decreased lordosis, lubrication, or vaginal and clitoral blood flow, and structural impairments, such as increased clitoral and vaginal fibrosis. Several possible mechanisms have been described including increased TGF-β, renin angiotensin system and endothelin/rho-kinase signaling, increased reactive oxygen species, and decreased nitric oxide/cGMP signaling.

Clinical Translation

In line with existing clinical studies, preclinical evidence supports that cardiometabolic diseases alter female genital tissue’s function and structure leading to impaired sexual arousal.

Strengths and Limitations

This masterclass paper gives an overview of the preclinical research assessing FSD in cardiometabolic disease. Limitations include the small number of studies that have assessed sexual function and arousal in female cardiometabolic animal models.

Conclusion

Preclinical evidence exists showing cardiometabolic diseases alter the structure and function of female genital tissues. However, similar to clinical studies, there are few studies to draw from, particularly in models of type 2 diabetes, obesity and metabolic syndrome. More studies are required using optimized animal models and methodology to confirm the mechanisms underlying cardiometabolic disease-induced FSD.
On model selection for dense stochastic block models
Authors: Norros Ilkka , Reittu Hannu , Bazsó Fülöp
Published: January 2022

This paper studies estimation of stochastic block models with Rissanen’s minimum description length (MDL) principle in the dense graph asymptotics. We focus on the problem of model specification, i.e., identification of the number of blocks. Refinements of the true partition always decrease the code part corresponding to the edge placement, and thus a respective increase of the code part specifying the model should overweight that gain in order to yield a minimum at the true partition. The balance between these effects turns out to be delicate. We show that the MDL principle identifies the true partition among models whose relative block sizes are bounded away from zero. The results are extended to models with Poisson-distributed edge weights.
Climate Change Litigation: Indian Perspective
Authors: Chaturvedi Eeshan
Published: January 2022

This article covers the recent trends in climate change litigation in India, capturing the peculiarities of the Indian judicial system that lend it the will, ability, and credibility to accommodate emerging principles of climate change laws within the law of the land. While tracing the historical underpinnings of judicial activism, environmental considerations, and strength of democratic institutions, this Article discusses some of the current developments in climate change case law in the country. Finally, in showcasing an increasing and immersive trend towards the inculcation of international principles of environmental law, this article establishes the dichotomy between an active judicial system applying international environmental principles at the domestic level and the roadblocks in terms of climate litigation in the recent times.
What and whom are family policies for? Unpacking the meaning of citizens’ support for family policy across Europe
Authors: Rakar Tatjana , Chung Heejung , Zimmermann Katharina , Schoyen Mi Ah , Filipovič Hrast Maša
Published: January 2022

The paper provides a comparative investigation into public attitudes to family policies. It shows that citizens’ support for family policies is diverse across different welfare regimes with respect to four countries belonging to distinct regimes: the United Kingdom, Germany, Norway and Slovenia. Using qualitative data, we unpack the ways individuals view the need for family policies, the rationale they use to explain their support for family policies and for imposing restrictions on access to family policies – ie. why, for whom and under which conditions. We find that social rights narratives are common in Norway; a social investment logic is prevalent in Germany and Slovenia; while in the United Kingdom, the dominant view is closer to the work-central individualised responsibility narrative of neoliberalism. In addition, we find differences across regimes in which family policies should target. In the United Kingdom and Germany, the focus is much more on providing support to activate parents, while in Norway and partly Slovenia, the focus is on providing well-being for children. The findings show that despite some convergence in family policies across Europe in recent times, we still find clear diversity in what and for whom family policies are for, its rationale largely embedded in the larger institutional normative structures of the welfare state. The results not only contribute to the literature on the relationship between public attitudes and welfare institutions, but also point towards shifting ideas about the role of family policies in the context of societal change.
The “Kāmūsī Corpus”: A Case Study in Manuscript Production and Knowledge Transmission in Ilkhanid Iran
Authors: De Nicola Bruno
Published: January 2022

The arrival of the Mongols in Iran in the thirteenth century made a deep impact on the political, economic, and religious life of the region. With the establishment of the Ilkhanate (1250–1335), the cultural life of Iran was also transformed. The territories under Mongol control saw the appearance of new architectural styles, a renaissance of Persian literature, and a burst in the production of Islamic manuscripts. Regarding this literary production, scholars have concentrated their efforts on studying important works composed in Mongol Iran either for their scientific, literary, or artistic value. However, most of this research focuses on individual manuscripts or specific works belonging to a concrete literary genre; these do not provide a holistic picture of the production, distribution, and consumption of the huge number of manuscripts surviving from the period. In an attempt to contribute to a more comprehensive understanding of this phenomenon, this study looks at six different manuscripts, jointly referred to as the “Kāmūsī corpus,” that share the rare characteristic of having all been copied by the same hand in fourteenth-century Iran. This article investigates the individuals involved in the production of these manuscripts, identifies the different works included in this corpus, and connects the production of these texts and the dissemination of knowledge in Ilkhanid Iran.
Stability and tip streaming of a surfactant-loaded drop in an extensional flow. Influence of surface viscosity
Authors: Herrada M.A. , Ponce-Torres A. , Rubio M. , Eggers J. , Montanero J.M.
Published: January 2022

We study numerically the nonlinear stationary states of a droplet covered with an insoluble surfactant in a uniaxial extensional flow. We calculate both the eigenfunctions to reveal the instability mechanism and the time-dependent states resulting from it, which provides a coherent picture of the phenomenon. The transition is of the saddle-node type, both with and without surfactant. The flow becomes unstable under stationary linear perturbations. Surfactant considerably reduces the interval of stable capillary numbers. Inertia increases the droplet deformation and decreases the critical capillary number. In the presence of the surfactant monolayer, neither the droplet deformation nor the stability is significantly affected by the droplet viscosity. The transient state resulting from instability is fundamentally different for drops with and without surfactant. Tip streaming occurs only in the presence of surfactants. The critical eigenmode leading to tip streaming is qualitatively the same as that yielding the central pinching mode for a clean interface, which indicates that the small local scale characterizing tip streaming is set during the nonlinear droplet deformation. The viscous surface stress does not significantly affect the droplet deformation and the critical capillary number. However, the damping rate of the dominant mode considerably decreases for viscous surfactants. Interestingly, shear viscous surface stress considerably alters the tip streaming arising in the supercritical regime, even for very small surface viscosities. The viscous surface stresses alter the balance of normal interfacial stresses and affect the surfactant transport over the stretched interface.
Turbulent entrainment in viscoelastic fluids
Authors: Abreu Hugo , Pinho Fernando T. , da Silva Carlos B.
Published: January 2022

Direct numerical simulations (DNS) of turbulent fronts spreading into an irrotational flow region are used to analyse the turbulent entrainment mechanism for viscoelastic fluids. The simulations use the FENE-P fluid model and are initiated from DNS of isotropic turbulence with Weissenberg and turbulence Reynolds numbers varying in the ranges $1.30 \le Wi \le 3.46$ and $206 \le Re_{\lambda }^{0} \le 404$, respectively. The enstrophy dynamics near the turbulent/non-turbulent interface (TNTI) layer, that separates regions of turbulent and irrotational flow, includes a new mechanism – the viscoelastic production – caused by the interaction between the vorticity field and the polymer stresses. This term can be a sink or a source of enstrophy in the turbulent core region of the flow, depending on the Weissenberg number, and contributes to the initial growth of the enstrophy in the viscous superlayer, together with the viscous diffusion, which is the only mechanism present for Newtonian fluids. For low and moderate Weissenberg numbers the scaling of the TNTI layer is similar to the scaling of TNTI layers for Newtonian fluids, but this is no longer the case at high Weissenberg numbers where the enstrophy tends to be concentrated into thin vortex sheets instead of vortex tubes. Finally, it is shown that the substantial decrease of the entrainment rates observed in turbulent flows of viscoelastic fluids, compared with Newtonian fluids, is caused by a reduction of the surface area and fractal dimension of the irrotational boundary, originated by the depletion of ‘active’ scales of motion in the fluid solvent caused by the viscoelasticity.
Influence of dynamic changes of workplace on organisational culture
Authors: Nanayakkara Kusal , Wilkinson Sara , Halvitigala Dulani
Published: January 2022

Challenged by the effects of organisational flexibility and high corporate real estate costs, organisations are increasingly seeking flexibility and operational efficiency in their office spaces. To date, the literature relating to flexible office spaces has focused mainly on their physical characteristics. The full effects of such spaces on human reactions and the corporate culture of organisations are less understood. The objective of this paper is to examine the influence of introducing activity-based working (ABW) on existing organisational culture. It was addressed from the perspective of the management of large corporate organisations. A mixed-method research that included a qualitative approach followed by a quantitative approach was adopted. The first stage included semistructured interviews with 19 large organisations who had introduced flexible layouts. The second stage involved a questionnaire survey of 32 organisations which had experienced office layout changes. Findings identify that the nature of workplace designs has a considerable impact on the corporate culture of an organisation and can be used to leverage and change its culture. Workplace designs directly influence culture by supporting the systems, symbols, engagement/motivation and behaviours of the organisation and employees. However, some differences between the perceptions of public and private organisations were identified. In conclusion, office layouts are artefacts that can either support, or change, the existing organisational culture. Therefore, the critical achievement of workspace design is to integrate the cultures, values and behaviours of organisations to meet their ultimate goals.

Sex differences in vitamin D metabolism, serum levels and action
Authors: Wierzbicka Alicja , Oczkowicz Maria
Published: January 2022

The ubiquity of vitamin D metabolising enzymes and vitamin D receptors in mammalian organisms suggests that vitamin D has pleiotropic effects. There are quite a few studies indicating the anticancer, cardioprotective and antidiabetic effects of vitamin D; however, the best-documented actions of vitamin D are the regulation of Ca–phosphate balance and its effect on immune function.

Vitamin D levels in organisms are modulated by many environmental and non-environmental factors. One potential factor that may influence vitamin D levels and effects is the sex of the individuals studied. This review focuses on the scientific evidence indicating different synthesis and metabolism of vitamin D in females and males, mainly from PubMed database sources. The article verifies the sex differences in vitamin D levels reported around the world. Moreover, the different effects of vitamin D on the musculoskeletal, cardiovascular, nervous and immune systems, as well as cancer in males and females, were discussed.

Most studies addressing sex differences in vitamin D levels and effects are observational studies with conflicting results. Therefore, carefully designed clinical trials and experiments on animal models should be carried out to determine the role of non-environmental factors that may differentiate vitamin D levels in females and males.
Making Americans: Spectacular Nationalism, Americanization, and Silent Film
Authors: STANCIU CRISTINA
Published: January 2022

Examining archival footage and documents about the cultural work of silent film during the 1910s and 1920s, this essay reveals the complicity of film with the work of organized Americanization at both federal and industrial levels. Specifically, it argues that early American cinema is complicit with and critical of Americanization, as it negotiates multiple new immigrant concerns. Joining the recent work of film and immigration historians, it argues that just as Americanization did not produce compliant citizens overnight, silent film as a new and powerful medium of persuasion could influence the new American viewers’ transformation only in part. Of particular interest is the use of film in industrial and educational contexts – which sometimes overlapped – purporting to both “educate” and Americanize the new immigrants to the US. It asks, what cultural work did silent film do for Americanization, the active and sometimes coercive campaign aiming to make new immigrants into good Americans? The films I read as case studies later in this essay – industrial, educational, and nontheatrical films such as An American in the Making (1913), The Making of an American (1920), and others – illustrate the potential of silent film both as mimesis (or representation of ideology) and as ideology.
Interpretation of observational studies: the good, the bad and the sensational
Authors: Ruxton Carrie
Published: January 2022

A Nutrition Society member-led meeting was held online on 18th January 2021 to discuss the role of observational studies in developing public health policy and dietary guidelines. In addition, participants debated media reporting of observational studies and the implications for public perception and trust in science. Speakers outlined the benefits of observational studies and how they fit within the suite of research tools available for estimating dietary intakes and determining their impact on health and disease risk. However, there are clear limitations, such as conscious and unconscious bias, measurement error, confounding and representativeness of populations. Researchers can overcome some of these issues with careful design, awareness of inter-individual variation, open and transparent reporting of findings, and hypothesis-driven statistical analysis to avoid multiple testing errors. Although there is evidence that data provided by nutritional epidemiology can be misleading, strong and thoughtful methodology including pre-registration, risk of bias assessment, awareness of confounders, and evidence grading can minimise potential bias, particularly when conducting systematic reviews. Translation of relative risk into population health impact is important and feeds into the need for responsible lay communication of results via mass media, especially regarding assumptions about cause and effect. Although use of mass media can bring benefits to academia, responsible dissemination is essential and starts with the press release. In conclusion, nutritional epidemiology is an important tool for exploring the risk/benefits of dietary patterns and contributing to health improvement via dietary guidelines, evidence-based policy and responsible lay communication provided its limitations are fully understood.
Magisterial authority and competing theories of natural law in Calvin'sInstitutes
Authors: Kincaid Elisabeth Rain
Published: January 2022

In this paper, I argue that John Calvin's problematic grant of magisterial authority to enforce proper religious worship contradicts much of his own political theology and in fact depends upon an ambiguity in his natural law theory. I demonstrate this ambiguity by examining the differing claims in theInstitutesregarding which of the tables of the Decalogue are accessible through natural law reasoning. I also consider the significance of this ambiguity for Calvin's political theology. I then suggest a partial retrieval of Calvin's political theology which is both more compelling to many contemporary Christians and in a better alignment with much of Calvin's own political theory.
Ransom theory in a new economy: Recontextualising a metaphor
Authors: Sutherland Andrew W.
Published: January 2022

This article demonstrates that an economic context is essential to the metaphor that Anselm of Canterbury and Peter Abelard used in their arguments against a ransom theory of atonement. Contrary to typical analyses, which suggest their metaphor makes a point about obedience or honour that slaves or servants owe to a master or king, this metaphor in fact suggests relations between the lord of a manor and his servi – serfs bound to the land, perpetually indebted to the lord and effectively considered his property. Should servi attempt to desert their lord, he had the right simply to reclaim them wherever they went. Insofar as this right voided the servus’ choice to leave their lord, the metaphorical framework of manorial economy ruled out the ‘rights of the devil’ in a way previous debt-slavery and military frameworks for ransom theory (in themselves) did not.
Will we see God's essence? A defence of a Thomistic account of the beatific vision
Authors: Ortlund Gavin
Published: January 2022

Recent discussion regarding the beatific vision has concerned the object of the vision. Thomas Aquinas represents a robust account of the beatific vision according to which God will be seen in his essence by saints and angels in heaven. Others, however, have worried that such a view risks imperilling divine transcendence and incomprehensibility and favour instead an understanding of the beatific vision that is christologically oriented. This article offers a defence of the claim that we will see God's essence in heaven. First, it draws attention to various distinctions in Thomas Aquinas’ Summa Theologiae concerning how we see the divine essence in heaven. Then, it demonstrates points of continuity between Thomas’ account and that of later Protestants, particularly Calvin and Turretin. Third, following Simon Gaine, it argues that Thomas’ account of the beatific vision is not christologically deficient. Finally, it argues that Thomas’ account has biblical support.
Comparison of dietary share of ultra-processed foods assessed with a FFQ against a 24-h dietary recall in adults: results from KNHANES 2016
Authors: Jung Sukyoung , Park Sohyun , Kim Jee Young
Published: January 2022

Objective:

To evaluate the performance of an FFQ for estimating dietary contributions of NOVA groups to individuals’ diets with a specific focus on ultra-processed foods (UPF) compared with a single 24-h dietary recall (24HR).

Design:

All consumed foods and beverages assess with both a 109-item FFQ and a single 24HR were classified into one of four NOVA groups: natural or minimally processed foods (MPF), processed culinary ingredients (PCI), processed foods (PF) and UPF. The contributions of each NOVA group to daily intakes of energy, protein, fat, saturated fat, carbohydrate, fibre and Na were expressed as crude intake, energy-adjusted intake and percentage intake. Mean differences, correlation coefficients and joint classification were calculated for intakes of energy and nutrients from each NOVA group between the FFQ and the 24HR.

Setting:

The Korea National Health and Nutrition Examination Survey 2016.

Participants:

Adults aged 19–64 years (n 3189).

Results:

The smallest group-mean differences between the two methods were observed in UPF (2–40 %). The greatest average Pearson’s correlation coefficients between the FFQ and 24HR were shown in dietary contributions of UPF (r = 0·22–0·25 for MPF; r = 0·02–0·05 for PCI; r = 0·11–0·18 for PF; r = 0·26–0·30 for UPF). The greatest agreement in quartile classification between the FFQ and the 24HR was observed in dietary contributions of UPF (70·0–71·5 % for MPF; 64·2–68·8 % for PCI; 66·9–69·2 % for PF; 71·8–73·9 % for UPF).

Conclusions:

The use of the FFQ for estimating absolute intake of UPF may not be encouraged in its current form, but it still may be used for relative comparisons such as quantile categorisation.
What is Wrong with the Recent Semiological Interpretation of Kant’s Religion
Authors: Pasternack Lawrence
Published: January 2022

In this article, I challenge the semiological interpretation of Kant’s Religion, particularly as advanced in recent years by James DiCenso and Allen Wood. As I here argue, their interpretations are neither compatible with broader aspects of Kant’s positive philosophy of religion, nor with how Kant himself describes the project of the Religion. Kant wrote the Religion in order to explore the compatibility between his theologically affirmative pure rational system of religion and Christian doctrines, particularly as understood by the Lutherans and Lutheran Pietists of his era, rather than as a treatise on how to make Christian theology compatible with contemporary secularism.
Writing the World at the End of Empire
Authors: Byrd Brandon R.
Published: January 2022

The mythmaking began in 1808. Soon after the Parliament of the United Kingdom passed an Act for the Abolition of the Slave Trade, the English abolitionist Thomas Clarkson published the first history of the movement that had led to the ban on the trafficking of enslaved Africans within the British Empire. It was a testament to British benevolence. A tribute to Christian virtue. “The abolition of the Slave-trade took its rise, not from persons, who set up a cry for liberty when they were oppressors themselves, nor from persons who were led to it by ambition or a love of reputation among men, but where it was most desirable, namely, from the teachers of Christianity in those times,” Clarkson proclaimed. In his telling, the inspiration for abolitionism had risen naturally from the same people who had dominated the transatlantic slave trade during the preceding century and would maintain colonial slavery for another three decades.

Published: January 2022

Existence of genetic divergence, appropriate characterization of breeding lines for economically important traits and determining parents with favourable alleles is the crux of crop genetic improvement programmes. This study is the first report of unravelling genetics and potential of petaloid-type cytoplasmic male sterile (pt-CMS) lines in carrot. Ten pt-CMS lines were crossed with 10 inbreds in line × tester mating fashion to generate 100 testcross progenies. Nutritional profiling of the 100 testcrosses progenies along with 20 parental types was carried out for two consecutive years for eight important traits to identify superior combiners. The pooled analysis revealed that the carotenoid content in root is under the genetic control of major genes (oligogenic). The pooled analysis revealed less than unity value of σ2A/D and σgca2/σsca2 for majority of the traits depicting preponderance of non-additive gene effects. The pt-CMS lines KT-28A, Kt-62A, KT-80A and KT-95A were identified as good combiners for carotenoids. The cross combination, KT-98A × KS-50 identified as the best heterotic combiner for CUPRAC and FRAP content over the years. Similarly, the combinations, KT-62A × KS-21, KT-80A × New Kuroda and KT-62A × KS-59 were found promising across the years for developing nutritionally rich F1 hybrids. The interaction analysis among the different antioxidant traits and plant pigments unveiled the scope of simultaneous improvement.
Increasing Future Precipitation in the Southwestern US in the Summer and Its Contrasting Mechanism With Decreasing Precipitation in the Spring
Authors: Liang Wengui , Zhang Minghua
Published: January 2022

It has been known that the southwestern United States (US) has experienced a drying trend during spring as climate warms. Less is known about the projected increase of summer precipitation in the region and its physical mechanisms. By using climate model simulations and moisture budget analysis, we show that in contrast to the spring, the changes of moisture gradient and wind convergence both cause increasing precipitation during summer. The change of the moisture gradient is featured by larger increase of water vapor along the western coast than inland, thus causing enhanced moisture advection in the future climate. The change of the wind convergence is caused by the maximum jet weakening over the continental US near the latitudes of the region, which leads to enhanced moisture convergence.
Crustal Thickening of the Northern Central Andean Plateau Inferred From Trace Elements in Zircon
Authors: Sundell Kurt E. , George Sarah W.M. , Carrapa Barbara , Gehrels George E. , Ducea Mihai N. , Saylor Joel E. , Pepper Martin
Published: January 2022

The timing of crustal thickening in the northern Central Andean Plateau (CAP), at 13–20°S, and its relationship to surface uplift is debated. Zircon qualitatively records crustal thickness as its trace element chemistry is controlled by the growth of cogenetic minerals and relative uptake of light and heavy Rare Earth Elements. Jurassic to Neogene zircons from volcanic rocks, sandstones, and river sediments reveal shifts in trace element ratios suggesting major crustal thickening at 80–55 Ma and 35–0 Ma, coincident with high‐flux magmatism. An intervening magmatic lull due to shallow subduction obscures the magmatic record from 55 to 35 Ma during which thickening continued via crustal shortening. Protracted thickening since the Late Cretaceous correlates with early elevation gain of the CAP western margin, but contrasts with Miocene establishment of near modern elevation in the northern CAP and the onset of hyperaridity along the Pacific coast, highlighting their complex spatial and temporal relationship.
Attribution of Observed Recent Decrease in Low Clouds Over the Northeastern Pacific to Cloud‐Controlling Factors
Authors: Andersen Hendrik , Cermak Jan , Zipfel Lukas , Myers Timothy A.
Published: January 2022

Marine low clouds cool the Earth's climate, with their coverage (LCC) being controlled by their environment. Here, an observed significant decrease of LCC in the northeastern Pacific over the past two decades is linked quantitatively to changes in cloud‐controlling factors. In a comparison of different statistical and machine learning methods, a decrease in the inversion strength and near‐surface winds, and an increase in sea surface temperatures (SSTs) are unanimously shown to be the main causes of the LCC decrease. While the decreased inversion strength leads to more entrainment of dry free‐tropospheric air, the increasing SSTs are shown to lead to an increased vertical moisture gradient that enhances evaporation when entrainment takes place. While the LCC trend is likely driven by natural variability, the trend‐attribution framework developed here can be used with any method in future analyses. We find the choice of predictors is more important than the method.
A New Perspective on Drought Propagation: Causality
Authors: Shi Haiyun , Zhao Yiyang , Liu Suning , Cai Hejiang , Zhou Zhaoqiang
Published: January 2022

The essence of propagation from meteorological to hydrological drought is the cause‐effect relationship between precipitation and runoff. This study challenged the reliability of applying linear or non‐linear correlation (i.e., closeness/similarity, a non‐directional scalar) to study drought propagation (i.e., causality, a directional vector). Meanwhile, in the field of hydrometeorology, causality analysis is burgeoning in model simulations, but still rare in analyzing the observations. Therefore, this study aims to provide a new perspective on drought propagation (i.e., causality) using convergent cross mapping (CCM) based on pure observations. Compared with the results in previous studies, the effectiveness of applying causality analysis in drought propagation study was proven, indicating that causality analysis would be more powerful than correlation analysis, especially for detecting drought propagation direction.
Plume‐Lithosphere Interaction and Delamination at Yellowstone and Its Implications for the Boundary of Craton Stability
Authors: Shi Ya‐Nan , Morgan Jason P.
Published: January 2022

Delamination of the lower lithosphere has occurred under different tectonic settings, thereby inducing strong lateral lithospheric strength heterogeneities. Here, we examine a recent case of plume‐induced lithosphere delamination associated with the Yellowstone plume. We propose that interaction between the Yellowstone plume and western North American lithosphere is what led to delamination of the lower lithosphere beneath the Columbia River Basalt (CRB) roughly ∼17 Myr ago. The excess melting that occurred when this “hole” was being filled by Yellowstone plume material was the primary trigger for the CRB excess melting event. The delaminated lower lithosphere currently lies to the northeast of the CRB; it can be clearly identified in recent seismic tomographic models. We suggest that both weak zones, for example, lithosphere‐crossing faults or suture zones, or vertical weaknesses associated with hotspot tracks, and strong zones (regions not underlain by weak mid‐lithosphere discontinuity material) can become the lateral boundaries of lithosphere delamination.
TAO Data Support the Existence of Large High Frequency Variations in Cross‐Equatorial Overturning Circulation

Large amplitude oscillations in the meridional overturning circulation (MOC) have been found near the equator in all major ocean basins in the NEMO ocean general circulation model. With periods of 3–15 days and amplitudes of ∼±100 Sv in the Pacific, these oscillations have been shown to correspond to zonally integrated equatorially trapped waves forced by winds within 10°N/S of the equator. Observations of dynamic height from the Tropical Atmosphere Ocean (TAO) mooring array in the equatorial Pacific also exhibit spectral peaks consistent with the dispersion relation for equatorially trapped waves. Here, we revisit the TAO observations to confirm that the amplitude of the oscillations is consistent with the simulations, supporting the modeled large amplitude MOC oscillations. We also show that the zonal structure of the frequency spectrum in both observations and simulations is predicted by changes in the baroclinic wave speed with variation in stratification across the ocean basin.

The tectonic evolution of the Paleo‐Jinshajiang Ocean, and in particular the time of its closure, is debated. Here we present new constraints on the evolution of this region from an integrated paleomagnetic and geochronologic study of the Late Triassic Batang Group volcanic rocks in Qamdo, Eastern Qiangtang Terrane (EQT). Two zircon U‐Pb ages indicate that the volcanic rocks erupted at ∼227–222 Ma. New paleomagnetic results yield a robust Late Triassic paleopole of 57.6°N, 176.4°E (A95 = 7.8°), corresponding to a paleolatitude of 32.5 ± 7.8°N for the study area. Integrated with other lines of paleomagnetic and geological evidence, we show that the northward drift of the EQT placed it at the same paleolatitude as the Tarim Block by ∼227–222 Ma, which suggests that the Paleo‐Jinshajiang Ocean in the Qamdo region closed before that time, and likely around ∼230 Ma.

Energetic electron flux enhancements for 100s keV energies are often observed at low L shells (L < 4) in the inner magnetosphere during geomagnetic storms. However, protons with similar energies do not penetrate as deeply as electrons. Electric fields from subauroral polarization streams (SAPS) have been proposed as a mechanism to explain the difference between the 100s keV electron and proton behavior by altering the particles’ drift paths and allowing electrons to access lower L shells than protons. Although the primary signature of SAPS is a strong radial electric field, there are corresponding westward/eastward azimuthal electric fields on the eastern/western regions of the SAPS that cause inward/outward radial transport and a differential response between the oppositely drifting electrons and protons. We examine three events where SAPS were observed by the Van Allen Probes near the same time and L shell range as 100s keV electron enhancements deep within the inner magnetosphere. The observations demonstrate that 100s keV electrons were progressively transported radially inward and trapped at low L shells that were consistent with the spatial extent of the SAPS electric fields. Proton flux enhancements were limited to <100 keV energies and were only observed temporarily in the SAPS region, indicating that these particles were on open drift paths. The particle observations are consistent with the differential drift paths for electrons and protons predicted by a simple SAPS electric field model, suggesting that SAPS play an important role in 100s keV particle dynamics at low L shells in the inner magnetosphere.
Reconstructing Fine‐Scale Ocean Variability via Data Assimilation of the SWOT Pre‐Launch In Situ Observing System

After the surface water and ocean topography (SWOT) satellite launches in 2022, an in‐situ field campaign will be conducted to estimate the ocean state for calibration and validation (CalVal) purposes. It is demonstrably difficult to capture the sea surface height (SSH) features that are the focus of SWOT, with short time periods (<20 days) and fine‐scale spatial structures (15–150 km). Therefore, a critical component of the SWOT CalVal will be a data assimilation (DA) system coupled to a primitive equation numerical model that can estimate: (a) the 2D SSH over the SWOT swaths, and (b) the 3D dynamical (velocity) field. To explore the ability of DA to meet the challenges of SWOT fine‐scale observations, a multiscale DA system based on an extended 3D variational method has been developed. Here, we present a strategic evaluation of this DA system, with a focus to assimilate in‐situ data from an observing system to best represent the fine‐scale ocean variability at the CalVal site. The DA estimate is compared to independent observations taken during the 2019 pre‐launch field campaign 300‐km off Monterey Bay, California. The key result is this DA system can reconstruct the upper 500‐m steric height with O(1‐cm) error at hourly resolution, and subcentimeter error for periods longer than 2 days.

Aeolis Mons (informally, Mount Sharp) exhibits a number of canyons, including Gediz and Sakarya Valles. Poorly sorted debris deposits are evident on both canyon floors and connect with debris extending down the walls for canyon segments that cut through sulphate‐bearing strata. On the floor of Gediz Vallis, debris overfills a central channel and merges with a massive debris ridge located at the canyon terminus. One wall‐based debris ridge is evident. In comparison, the floor of Sakarya Vallis exhibits a complex array of debris deposits. Debris deposits on wall segments within Sakarya Vallis are mainly contained within chutes that extend downhill from scarps. Lateral debris ridges are also evident on chute margins. We interpret the debris deposits in the two canyons to be a consequence of one or more late‐stage hydrogeomorphic events that increased the probability of landslides, assembled and channelized debris on the canyon floors, and moved materials down‐canyon. The highly soluble nature of the sulphate‐bearing rocks likely contributed to enhanced debris generation by concurrent aqueous weathering to produce blocky regolith for transport downslope by fluvial activity and landslides, including some landslides that became debris flows. Subsequent wind erosion in Gediz Vallis removed most of the debris deposits within that canyon and partially eroded the deposits within Sakarya Vallis. The enhanced wind erosion within Gediz Vallis was a consequence of the canyon's alignment with prevailing slope winds.
