Refinement of the Hardening Soil model within the small strain range
Authors: Cudny Marcin , Truty Andrzej 
Published: March 2020

AbstractThe popularity of the elasto-plastic Hardening Soil (HS) model is based on simple parameter identification from standard testing and empirical formulas. The HS model is implemented in many commercial FE codes designed to analyse geotechnical problems. In its basic version, the stress–strain behaviour within the elastic range is subject to the hypoelastic power law, which assures the barotropy of the elastic stiffness. However, a proper modelling within the small strain range, i.e. strain-induced stiffness degradation and correct reproduction of the hysteretic behaviour, was one of the most important drawbacks in the HS formulation. The first small strain stiffness extension to the HS model was proposed by Benz (Small strain stiffness of soils and its numerical consequences, 2007), and the new model was called Hardening Soil Small (HSS). Despite the simple isotropic formulation, its applicability was proved in various numerical simulations in geotechnics. However, the HSS formulation exhibits a serious fault known in the literature as overshooting, i.e. uncontrolled reset of the loading memory after tiny unloading–reloading cycles. The authors' main aim was to retain the set of material parameters for the HSS formulation and to propose a new small strain extension to the HS model without overshooting. The new proposal is based on theBrickmodel which represents the concept of nested yield surfaces in strain space. The implementation aspects of the new HS-Brick model are described, and its performance is presented in some element tests and selected boundary value problems by comparisons with the HSS formulation.
Protests in Hong Kong (2019–2020): a Perspective Based on Quality of Life and Well-Being
Authors: Shek Daniel T. L. 
Published: March 2020

AbstractTriggered by the Fugitive Offenders and Mutual Legal Assistance in Criminal Matters Legislation (Amendment) Bill 2019 in Hong Kong (Extradition Bill), many protests have taken place in Hong Kong in 2019–2020. Using a perspective based on quality of life and well-being in different ecological systems, it is argued that the process of introducing the Bill is the “heat” which has ignited the “fuels” represented by 12 pre-existing and new issues in quality of life and well-being. These issues included distrust in the Central Government, lack of national identity, political dissatisfaction, economic strains, mental health threats, drop in family quality of life, lack of life skills education, lack of evidence-based national education in the formal curriculum, slow response of the Government, and alleged excessive use of force by the police. The fire has been intensified by “four strong winds”, including disinformation and misinformation, anonymity of the protesters, public support for the students, and support given by parties outside Hong Kong. Possible solutions in terms of promotion of quality of life and well-being with reference to the fire triangle are discussed.
David Martin’s The Religious and the Secular (1969): an Underestimated Masterwork in the Study of Western Secularization
Authors: Brewitt-Taylor Sam 
Published: March 2020

AbstractThis article considers the content and reception of David Martin’s The Religious and the Secular (1969), a brilliant text whose revolutionary implications were overlooked by most of the next two generations of secularization scholarship because it was so far ahead of its time. The young Martin was able to unmask the ideological nature of the secular project partly due to his knowledge of theology, partly due to his eclectic reading, and partly because he was writing at a time when secularity was only just achieving cultural hegemony in Anglophone cultures. Fifty years later, now that postsecular scholarship is beginning to deconstruct the secular project, Martin’s anthology re-emerges as a vital early text in the new paradigm in secularization studies.
Alternative Strategies Toward Sustainable Ammonia Synthesis

Published: March 2020

AbstractAs one of the world’s most produced chemicals, ammonia (NH3) is synthesized by Haber–Bosch process. This century-old industry nourishes billions of people and promotes social and economic development. In the meantime, 3%–5% of the world’s natural gas and 1%–2% of the world’s energy reserves are consumed, releasing millions of tons of carbon dioxide annually to the atmosphere. The urgency of replacing fossil fuels and mitigating climate change motivates us to progress toward more sustainable methods for N2 reduction reaction based on clean energy. Herein, we overview the emerging advancement for sustainable N2 fixation under mild conditions, which include electrochemical, photo- , plasma-enabled and homogeneous molecular NH3 productions. We focus on NH3 generation by electrocatalysts and photocatalysts. We clarify the features and progress of each kind of NH3 synthesis process and provide promising strategies to further promote sustainable ammonia production and construct state-of-the-art catalytic systems.

AbstractThe Mobile Asteroid Surface Scout (MASCOT), an Asteroid Lander carried by the Hayabusa2 spacecraft, successfully landed on the Near-Earth Asteroid (162173) Ryugu on October 03, 2018. Thereby accomplishing the first-ever landing of a European spacecraft on the surface of this type of celestial body. MASCOT was a prototype design of a new class of nano-size surface science packages for the exploration of small solar system bodies. The very low gravity (thus, very low escape velocity) of the target body required the design of a miniaturized deployment mechanism with a relatively small, well-reproducible separation velocity. In addition, the mechanism also had to safely restrain the lander to the mother spacecraft during the launch and its 3.5-year cruise phase. In this paper, we describe in detail the design, numerical analysis and test of this newly developed separation mechanism. Furthermore, we compare the mechanism to other existing deployment systems and verify its performance with two independent analysis methods using actual flight data taken during the ultimate flight activation event, which initiated the successful delivery and surface operation of the MASCOT asteroid lander.
Local Gender Norms: Persistence or Change? Reply to “A Gendered Resource Curse? Mineral Ownership, Female Unemployment and Domestic Violence in Sub-Saharan Africa” by Mario Krauser, Tim Wegenast, Gerald Schneider, and Ingeborg Elgersmar
Authors: Neupert-Wentz Clara 
Published: March 2020

AbstractIn their recent article “A Gendered Resource Curse? Mineral Ownership, Female Unemployment and Domestic Violence in Sub-Saharan Africa,” Mario Krauser, Tim Wegenast, Gerald Schneider, and Ingeborg Elgersmar argue that international mine ownership alters employment possibilities for women in comparison to domestically-owned mines. They make the case that this also alters gender norms and find that foreign ownership decreases domestic violence reporting from women. In this reply, I take a closer look at the proposed mechanisms that local gender norms change around international mines and will review literature that finds persisting effects of gender norms on gender equality. Finally, I will assess the circumstance under which norms may change in response to outside interventions and suggest avenues for future research.

Abstract

Background
Climacturia is an under-reported complication of definitive therapy for prostate cancer (PCa) - that is, radical prostatectomy (RP) and/or radiation therapy (RT).

Aim
We sought to identify the prevalence and predictors of climacturia and associated patient/partner bother in patients with and without prior PCa treatment.

Methods
We analyzed a database of patients who presented to our Men's Health clinic and filled out a questionnaire related to sexual function and pertinent medical histories. The prevalence of climacturia and associated patient/partner bother in patients with/without prior RP/RT was calculated. Univariable and multivariable logistic regressions were performed to identify predictors associated with climacturia and patient/partner bother.

Outcomes
The primary outcomes were the prevalence and predictors of climacturia and associated patient/partner bother in patients with/without history of definitive PCa treatment.

Results
Among 1,117 patients able to achieve orgasm, 192 patients (17%) had prior history of definitive therapy for PCa (RP alone = 139 [72%]; RT alone = 22 [11%]; RP + RT = 31 [16%]). Climacturia was reported by 39%, 14%, 52%, and 2.4% of patients with history of RP alone, RT alone, RP + RT, and neither RP nor RT, respectively (P &lt; .05 between all groups). 33 to 45 percent of patients with climacturia noted significant patient/partner bother. Factors significantly associated with climacturia were prior RP, prior RT, history of other prostate surgery, and erectile dysfunction, although erectile dysfunction was not significant on multivariable analysis. Significant reduction in climacturia prevalence was noted for patients who were ≥1 year out from RP, compared with patients who were &lt;1 year out.
Among patients with prior RP/RT, stress urinary incontinence was associated with increased risk of climacturia, whereas diabetes was associated with decreased risk. No factors were associated with patient/partner bother. Among patients with prior RP, nerve-sparing technique did not predict presence of climacturia but was associated with reduced patient/partner bother.

Clinical translation
Given significant prevalence of climacturia and associated patient/partner bother, patients should be counseled on the risk of climacturia before undergoing RP/RT.

Strengths and limitations
Strengths include the large study population and the focus on both RP and RT. Limitations include the facts that this is a single-institution study that primarily relies on patients’ subjective reporting and that the study population may not represent the general population.

Conclusions
Climacturia affects a significant proportion of patients with history of RP/RT for PCa, and many patients and their partners find this bothersome.
Democratising food: The case for a deliberative approach
Authors: Thompson Merisa S. , Cochrane Alasdair , Hopma Justa 
Published: March 2020

AbstractPrevailing political and ethical approaches that have been used to both critique and propose alternatives to the existing food system are lacking. Although food security, food sovereignty, food justice, and food democracy all offer something important to our reflection on the global food system, none is adequate as an alternative to the status quo. This article analyses each in order to identify the prerequisites for such an alternative approach to food governance. These include a focus on goods like nutrition and health, equitable distribution, supporting livelihoods, environmental sustainability, and social justice. However, other goods, like the interests of non-human animals, are not presently represented. Moreover, incorporating all of these goods is incredibly demanding, and some are in tension. This raises the question of how each can be appropriately accommodated and balanced. The article proposes that this ought to be done through deliberative democratic processes that incorporate the interests of all relevant parties at the local, national, regional, and global levels. In other words, the article calls for adeliberativeapproach to thedemocratisationof food. It also proposes that one promising potential for incorporating the interests of all affected parties and addressing power imbalances lies in organising the scope and remit of deliberation aroundfood type.
Measuring Burnout in Social Work

Published: March 2020

Abstract. Several studies challenge the three-dimensional structure of the Maslach Burnout Inventory – Human Services Survey (MBI-HSS), citing alternative measurement models including bifactor models. While bifactor models have merit, if data sampling violates assumptions of Stochastic Measurement Theory (SMT) the bifactor model requires modification prior to application. The present study compared five alternative MBI-HSS factor models using both Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM). Data from a cross-sectional survey of United Kingdom (UK) social workers were examined ( N = 1257), with validation analyses conducted in an independent sample ( N = 162). Bifactor models, re-specified to account for SMT, provided good fit. However, improved fit was observed for a bifactor-ESEM specification, in both test (χ2 = 1,112.93, df = 149, p < .001, CFI = .969, RMSEA = .072, 90% CI [.068, .076]) and validation (χ2 = 227.89, df = 149, p < .001, CFI = .978, RMSEA = .057, 90% CI [.042, .072]) samples. The results confirm the MBI-HSS possesses a bifactor structure in UK social workers when SMT is considered, and that bifactor-ESEM may provide a better framework to examine MBI-HSS.

Published: March 2020

AbstractThe SMART‐s (Spectral Measurements for Atmospheric Radiative Transfer—spectroradiometer) acquires Sun/sky observations for retrieving optimal information on trace gases and aerosols with minimal assumptions. Overall, the algorithm of SMART‐s incorporates a series of retrievals, from fundamental quantities (i.e., column abundance of trace gases and aerosol loading) to higher‐order geophysical parameters (e.g., aerosol physicochemical properties and vertical profiles), utilizing Sun/sky spectral radiance measurements. This paper describes the theoretical basis for column retrievals of trace gases and aerosols. Associated profile retrievals will be presented in follow‐up papers. The current algorithm retrieves the fine/coarse mode of the particle size distribution and spectral complex index of refraction and, thereby, the spectral aerosol single‐scattering albedo ω0. SMART‐s retrieval is unique particularly in its high spectral resolution of the complex index of refraction and ω0 from near‐ultraviolet to near‐infrared wavelengths, which is pivotal information for atmospheric chemistry, climate and other inversions. We theoretically assessed information content and retrieval accuracy of the algorithm and compared different type of measurements including the Aerosol Robotic Network (AERONET) and standard Pandora. For the same levels of radiometric accuracy, SMART‐s measurements provide the most informative aerosol retrievals based on theoretical error analyses. Higher spectral resolution measurements are particularly beneficial for particle size distribution and fine‐mode refractive index retrievals. We applied this algorithm to the AERONET Sun/sky measurements at Kanpur, India, in 2016 to assess algorithm consistency. Even with different assumptions and numerical methods for the inversion, SMART‐s retrieved aerosol parameters agreed well with the AERONET operational products (e.g., absolute mean bias errors less than 0.01 for ω0).
Hydraulic Potential Energy Model for Hydropower Operation in Mixed Reservoir Systems
Authors: Wan Wenhua , Wang Hao , Zhao Jianshi 
Published: March 2020

AbstractThe forecast‐informed hydropower operation for mixed reservoir systems, which consist of parallel and cascade reservoirs, is of considerable importance in practice; however, this operation still lacks an analytical basis in theory. From the perspective of energy, this paper introduces the concept of “hydraulic potential energy” and mathematically derives the energy transformation formula for multi‐reservoir hydropower operation. Based on this formula and the rolling single‐period forecast, a maximum hydraulic potential energy model (E1 model) is proposed. The presented rigorous proofs demonstrate the deficiencies of the commonly considered objectives or principles of minimizing the outflow‐induced energy‐cost, while the objective function of the E1 model is demonstrated to be superior. If the constraints of power output and reservoir storage are nonbinding, the derived optimal spatial principle for hydropower operation is (1) to equalize the Relative Marginal Energy (RME) among reservoirs or (2) if this status is not feasible, to release water and generate hydropower first from the reservoirs that have the largest RME values. Considering the uncertainty of future inflow, the E1 model is extended to the two‐stage hydraulic potential energy model (E2 model). A case study of a hypothetical mixed three‐reservoir system demonstrates the superior performance of the E2 model compared with the conventional K‐value principle and the minimum energy‐cost model. This paper provides an innovative spatial principle and a practical model for the realization of forecast‐informed hydropower operation, which contributes to the optimization of the large‐scale energy market.

Abstract
Sediment-hosted CO2-rich aquifers deep below the Colorado Plateau (USA) contain a remarkable diversity of uncultivated microorganisms, including Candidate Phyla Radiation (CPR) bacteria that are putative symbionts unable to synthesize membrane lipids. The origin of organic carbon in these ecosystems is unknown and the source of CPR membrane lipids remains elusive. We collected cells from deep groundwater brought to the surface by eruptions of Crystal Geyser, sequenced the community, and analyzed the whole community lipidome over time. Characteristic stable carbon isotopic compositions of microbial lipids suggest that bacterial and archaeal CO2 fixation ongoing in the deep subsurface provides organic carbon for the complex communities that reside there. Coupled lipidomic-metagenomic analysis indicates that CPR bacteria lack complete lipid biosynthesis pathways but still possess regular lipid membranes. These lipids may therefore originate from other community members, which also adapt to high in situ pressure by increasing fatty acid unsaturation. An unusually high abundance of lysolipids attributed to CPR bacteria may represent an adaptation to membrane curvature stress induced by their small cell sizes. Our findings provide new insights into the carbon cycle in the deep subsurface and suggest the redistribution of lipids into putative symbionts within this community.
Organoid cultures of MELAS neural cells reveal hyperactive Notch signaling that impacts neurodevelopment

Published: March 2020

AbstractMutations in mitochondrial DNA (mtDNA), typically maternally inherited, can result in severe neurological conditions. There is currently no cure for mitochondrial DNA diseases and treatments focus on management of the symptoms rather than correcting the defects downstream of the mtDNA mutation. Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) is one such mitochondrial disease that affects many bodily systems, particularly the central nervous system and skeletal muscles. Given the motor deficits seen in MELAS patients, we investigate the contribution of motor neuron pathology to MELAS. Using a spinal cord organoid system derived from induced pluripotent stem cells of a MELAS patient, as well as its isogenically corrected control, we found that high levels of Notch signaling underlie neurogenesis delays and neurite outgrowth defects that are associated with MELAS neural cultures. Furthermore, we demonstrate that the gamma-secretase inhibitor DAPT can reverse these neurodevelopmental defects.
“Iron free” zinc oxide nanoparticles with ion-leaking properties disrupt intracellular ROS and iron homeostasis to induce ferroptosis

Published: March 2020

AbstractExposure to nanomaterials (NMs) is an emerging threat to human health, and the understanding of their intracellular behavior and related toxic effects is urgently needed. Ferroptosis is a newly discovered, iron-mediated cell death that is distinctive from apoptosis or other cell-death pathways. No evidence currently exists for the effect of “iron free” engineered NMs on ferroptosis. We showed by several approaches that (1) zinc oxide nanoparticles (ZnO NPs)-induced cell death involves ferroptosis; (2) ZnO NPs-triggered ferroptosis is associated with elevation of reactive oxygen species (ROS) and lipid peroxidation, along with depletion of glutathione (GSH) and downregulation of glutathione peroxidase 4 (GPx4); (3) ZnO NPs disrupt intracellular iron homeostasis by orchestrating iron uptake, storage and export; (4) p53 largely participates in ZnO NPs-induced ferroptosis; and (5) ZnO particle remnants and dissolved zinc ion both contribute to ferroptosis. In conclusion, our data provide a new mechanistic rationale for ferroptosis as a novel cell-death phenotype induced by engineered NMs.
Interaction of 2D materials with liquids: wettability, electrochemical properties, friction, and emerging directions

Published: March 2020

AbstractThe emergence of two-dimensional (2D) materials as functional surfaces for sensing, electronics, mechanics, and other myriad applications underscores the importance of understanding 2D material–liquid interactions. The thinness and environmental sensitivity of 2D materials induce novel surface forces that drive liquid interactions. This complexity makes fundamental 2D material–liquid interactions variable. In this review, we discuss the (1) wettability, (2) electrical double layer (EDL) structure, and (3) frictional interactions originating from 2D material–liquid interactions. While many 2D materials are inherently hydrophilic, their wettability is perturbed by their substrate and contaminants, which can shift the contact angle. This modulation of the wetting behavior enables templating, filtration, and actuation. Similarly, the inherent EDL at 2D material–liquid interfaces is easily perturbed. This EDL modulation partially explains the wettability modulation and enables distinctive electrofluidic systems, including supercapacitors, energy harvesters, microfluidic sensors, and nanojunction gating devices. Furthermore, nanoconfinement of liquid molecules at 2D material surfaces arising from a perturbed liquid structure results in distinctive hydrofrictional behavior, influencing the use of 2D materials in microchannels. We expect 2D material–liquid interactions to inform future fields of study, including modulation of the chemical reactivity of 2D materials via tuning 2D material–liquid interactions. Overall, 2D material–liquid interactions are a rich area for research that enables the unique tuning of surface properties, electrical and mechanical interactions, and chemistry.
