Published: April 2022

This study aimed to determine whether higher intakes of Na, added sugars and saturated fat are prospectively associated with all-cause mortality and CVD incidence and mortality in a diverse population. The nationally representative Canadian Community Health Survey-Nutrition 2004 was linked with the Canadian Vital Statistics – Death Database and the Discharge Abstract Database (2004–2011). Outcomes were all-cause mortality and CVD incidence and mortality. There were 1722 mortality cases within 115 566 person-years of follow-up (median (interquartile range) of 7·48 (7·22–7·70) years). There was no statistically significant association between Na density or energy from saturated fat and all-cause mortality or CVD events for all models investigated. The association of usual percentage of energy from added sugars and all-cause mortality was significant in the base model with participants consuming 11·47 % of energy from added sugars having 1·34 (95 % CI 1·01, 1·77) times higher risk of all-cause mortality compared with those consuming 4·17 % of energy from added sugars. Overall, our results did not find statistically significant associations between the three nutrients and risk of all-cause mortality or CVD events at the population level in Canada. Large-scale linked national nutrition datasets may not have the discrimination to identify prospective impacts of nutrients on health measures.
Effect of cold storage on development and demographic parameters ofScolothrips longicornisfed on two-spotted spider mite
Authors: Pakyari Hajar
Published: April 2022

Cold storage effects on the female predatory thripsScolothrips longicornisPriesner (Thysanoptera: Thripidae) fed onTetranychus urticaeKoch eggs for different time periods (5, 10, 20 and, 30 days) at 5 or 25 °C (control) on development and life table parameters were examined. Female adult duration and female total longevity were not influenced by the period of cold storage. The minimum mean female total longevity (28.1 ± 0.32 day) was observed in the 30-day treatment. The oviposition period decreased with increasing cold storage duration. All life table parameters ofS. longicornisdemonstrated a significant difference across treatments. Our results demonstrated that the female adult ofS. longicorniscould be maintained at 5 °C for 5-days with minimal reduction in the life-history process. This would be beneficial in the storage and mass production ofS. longicornisin biocontrol programs involvingT. urticae.
Shareholder Litigation and Corporate Social Responsibility
Authors: Freund Steven , Nguyen Nam H. , Phan Hieu V.
Published: April 2022

This research examines the relation between shareholder litigation and corporate social responsibility (CSR). Exploiting exogenous changes in shareholder litigation rights following the staggered adoption of universal demand laws by U.S. states and the Ninth Circuit Court of Appeals’ ruling on securities class action lawsuits, we show that weaker shareholder litigation rights lead to lower CSR scores. Moreover, the relation is stronger for firms facing higher litigation risk, and a decreased CSR score enhances firm value. Our evidence suggests that firms engage in CSR activities partly to reduce shareholder litigation risk ex ante and mitigate its consequences ex post.
Effect of the nasal airflow inducing manoeuvre on olfaction and quality of life after laryngectomy
Authors: Subbaraj R , Mathews S S , Bedford S , Michael R C , Albert R R A , Rupa V
Published: April 2022

Objective

To assess the effectiveness of the nasal airflow inducing manoeuvre or ‘polite yawn’ technique in improving olfaction and quality of life in laryngectomised patients.

Methods

Using a prospective study design, 42 patients scheduled to undergo laryngectomy at a tertiary care centre were subjected to olfaction testing before surgery and two weeks following the surgery. The nasal airflow inducing manoeuvre was taught, and the olfaction test was repeated with the patient performing the nasal airflow inducing manoeuvre. Quality of life was assessed using the Appetite, Hunger and Sensory Perception questionnaire with calculation of scores after the patient had learnt the nasal airflow inducing manoeuvre.

Results

There was a significant reduction in the composite olfaction score, from a mean (standard deviation) baseline value of 4.01 (1.39) to 0.44 (0.51), two weeks after surgery (p < 0.001). After practising the nasal airflow inducing manoeuvre, the olfaction scores increased to 3.05 (1.32) (p < 0.001). Appetite, Hunger and Sensory Perception questionnaire scores ranged from 52 to 110 (normal range, 29–145), suggesting an improvement in the quality of life of patients.

Conclusion

The nasal airflow inducing manoeuvre, an inexpensive, simple, patient-friendly manoeuvre, can be used in the olfaction rehabilitation of patients undergoing laryngectomy.

This article introduces this special volume on the Mughal policy of sulh-i kull by situating the collection of articles in relation to broader developments across Eurasia.

The Catholic inquisitors of Europe who defended nonsense by cruelty,

might have been confounded by the example of a barbarian,

who anticipated the lessons of philosophy and established by his laws

a system of pure theism and perfect toleration…a singular conformity

may be found between the religious laws of Zingis Khan and Mr. Locke.

Published: April 2022

Background

Identification of treatment-specific predictors of drug therapies for bipolar disorder (BD) is important because only about half of individuals respond to any specific medication. However, medication response in pediatric BD is variable and not well predicted by clinical characteristics.

Methods

A total of 121 youth with early course BD (acute manic/mixed episode) were prospectively recruited and randomized to 6 weeks of double-blind treatment with quetiapine (n = 71) or lithium (n = 50). Participants completed structural magnetic resonance imaging (MRI) at baseline before treatment and 1 week after treatment initiation, and brain morphometric features were extracted for each individual based on MRI scans. Positive antimanic treatment response at week 6 was defined as an over 50% reduction of Young Mania Rating Scale scores from baseline. Two-stage deep learning prediction model was established to distinguish responders and non-responders based on different feature sets.

Results

Pre-treatment morphometry and morphometric changes occurring during the first week can both independently predict treatment outcome of quetiapine and lithium with balanced accuracy over 75% (all p < 0.05). Combining brain morphometry at baseline and week 1 allows prediction with the highest balanced accuracy (quetiapine: 83.2% and lithium: 83.5%). Predictions in the quetiapine and lithium group were found to be driven by different morphometric patterns.

Conclusions

These findings demonstrate that pre-treatment morphometric measures and acute brain morphometric changes can serve as medication response predictors in pediatric BD. Brain morphometric features may provide promising biomarkers for developing biologically-informed treatment outcome prediction and patient stratification tools for BD treatment development.
In the cradle of laws: resolving coalition controversies in the executive phase of law-making
Authors: Lysek Jakub , Zbíral Robert
Published: April 2022

Law-making in most parliamentary democracies is dominated by the executive. Yet so far, all research has focused on the parliamentary stage of law-making. Studies suggest that the changes to bills submitted by coalition governments are the result of coalition policies dealing with the agency loss caused by ministerial drift. This is puzzling because it is already easier and more effective for coalition parties to attempt to change the bills in the executive phase than in the parliamentary one. The article aims to close the knowledge gap, and it quantitatively explores the factors that facilitate changes during the understudied executive phase on case study of the Czech Republic. Analysis reveals that government bills are altered more during the executive phase than the parliamentary phase. While we find no significant impact caused by the distance to coalition compromise, the saliency of a bill for coalition partners has a negative influence on the ratio of changes.
Permission to bail out EU’s national flag carriers? Technocratic and political determinants of commission approval of state aid to national airlines in difficulties in the pre-COVID era
Authors: van Druenen Ruud
Published: April 2022

The enforcement of EU state aid rules is often portrayed as mainly driven by technocratic standards, but there are indications that political factors also play a role. However, their exact impact and relationship with technocratic factors remain unknown. This article studies under which technocratic and political conditions the Commission approves or does not approve state aid to national airlines. Based on a crisp-set Qualitative Comparative Analysis of all 14 cases of alleged state aid to national airlines between 2004 and 2019, the article shows that both the approval and non-approval of aid are predominantly dependent upon the Commission’s technocratic assessment: a low degree of market distortion turns out to be a sufficient condition for the approval of aid, whereas a high degree of market distortion is a necessary condition for the non-approval of aid. However, in some cases, political factors are decisive in determining enforcement outcomes.
Changes in the potential distribution of valuable tree species based on their regeneration in the Neotropical seasonal dry forest of north-western Argentina
Authors: Alabar Fabio , Politi Natalia , Názaro Paula , Amoroso Mariano , Rivera Luis
Published: April 2022

The distribution of regeneration makes it possible to assess whether populations of tree species will maintain or change their distributions. For Neotropical dry forests there is little information on the potential changes in the distribution of tree species. Here, we evaluate the potential distributions of adults and seedlings of eight timber tree species of the Piedmont Forest of north-western Argentina by recording the presence of seedlings and adults in plots and modelling with MaxEnt software using three bioclimatic variables. The potential distribution areas of seedlings and adults and the percentage of overlap of seedlings with respect to adults were calculated. The potential distribution for adults was 694 457 ± 62 535 ha, and this figure was 656 564 ± 194 769 ha for seedlings. The potential distribution of seedlings of Calycophyllum multiflorum covered the smallest area (184 496 ha) and had the least overlap with the adults (18%). The difference in the overlap of the potential distribution areas between adults and seedlings suggests that there could be changes in the future distribution of this tree species and C. multiflorum should therefore be the focus of conservation strategies so that the species can follow its bioclimatic niche as the climate changes.
Patterns of moss richness in Admiralty Bay, King George Island, cannot be explained by geological or ornithogenic drivers alone

Published: April 2022

We set out to document the diversity and distribution of bryophytes in Admiralty Bay and thereby enable the identification of patterns in local diversity and their possible drivers. Combining data extracted from different sources and recent collections, we documented the presence of 63 species. Similarity analyses of moss species diversity in relation to underlying geology and ornithogenic influence identified an identical cophenetic correlation coefficient of 0.744 for both factors. The Sørensen index was < 0.6, indicating that the groups share < 60% of the species recorded. The data showed that the selected filters (ornithogenic soils, non-ornithogenic soils and different geological extracts) did not underlie consistent species groupings, and we conclude that other environmental and topographical factors are likely to be responsible for shaping the moss community structure in Admiralty Bay. To enable effective management of Antarctic Specially Managed Area (ASMA) No. 1 and Antarctic Specially Protected Area (ASPA) No. 128, robust assessments of the local ecosystem and biodiversity are necessary to assist in the decision-making processes mandated under the Antarctic Treaty System, one of whose founding principles is the preservation of the Antarctic ecosystem.
Latent classes in preschoolers’ internal working models of attachment and emotional security: Roles of family risk
Authors: Speidel Ruth , Behrens Brigid , Lawson Monica , Mark Cummings E. , Valentino Kristin
Published: April 2022

Children’s relationships inform their internal working models (IWMs) of the world around them. Attachment and emotional security theory (EST) emphasize the importance of parent–child and interparental relationships, respectively, for IWM. The current study examined (a) data-driven classes in child attachment and emotional security IWM, (b) associations between IWM classes and demographic variables, maltreatment, intimate partner violence (IPV), and maternal depressive symptoms, and (c) consistency in attachment and emotional security IWM classes, including as a function of maltreatment, IPV, and maternal depressive symptoms. Participants were 234 preschool-aged children (n= 152 experienced maltreatment andn= 82 had not experienced maltreatment) and their mothers. Children participated in a narrative-based assessment of IWM. Mothers reported demographics, IPV, and maternal depressive symptoms. Latent class analyses revealed three attachment IWM classes and three emotional security IWM classes. Maltreatment was associated with lower likelihood of being in the secure attachment class and elevated likelihood of being in the insecure dysregulated attachment class. Inconsistencies in classification across attachment and emotional security IWM classes were related to maltreatment, IPV, and maternal depressive symptoms. The current study juxtaposes attachment and EST and provides insight into impacts of family adversity on children’s IWM across different family relationships.
Passing Stigma: Negotiations of Welfare Categories as Street Level Governmentality
Authors: Boland Tom , Doyle Kenny , Griffin Ray
Published: April 2022

Stigma is not the automatic outcome of power differentials, but a distinctive moral inscription generated through cultural evaluations and governmental processes. Research on welfare recipients records how the unemployed displace stigma onto other welfare recipients, positioning other(ed) claimants as the ‘real unemployed’ or ‘scroungers’. Theoretically we adapt Butler’s analysis of the psychic processes whereby subjects are formed by disavowal of discourses which abjectify them. Arguably, this is functional for the governmentalising processes of generating jobseeking, with a latent function of reinforcing activation policies. Drawing on qualitative interviews, we trace how Irish individuals negotiate the stigma attributed to or foisted upon Welfare claimants, in welfare offices and informal social interactions and in job interviews – how they attempt to ‘pass’ as good JobSeekers and pass stigma on to others. Curiously, many welfare claimants suggest governmental interventions for distinguishing and discriminating between the deserving and undeserving adopting the stigmatising perspective.
Framing and Shaming: The 2017 Welfare Cheats, Cheat Us All Campaign
Authors: Power Martin J. , Devereux Eoin , Ryan Majka
Published: April 2022

The repeated circulation of anti-welfare discourses has served to encourage limited and often incorrect public understandings of issues pertaining to welfare. Central to these processes is the social construction of notions of ‘deservedness’ and ‘undeservedness.’ In this article we examine the 2017 ‘Welfare Cheats, CheatUs All’ (original emphasis) campaign initiated by the Department of Social Protection in the Republic of Ireland. We present our analysis of the dominant discourses evident in the campaign itself and the in-house discussions in the lead up to the campaign. Our article shows that this Irish campaign rehearses a familiar international discourse which follows distinct patterns or rules, and we evidence, in keeping with other moral panics, the spurious nature of the data being used to exaggerate the scale and extent of welfare ‘fraud’.
A Multi-Dimensional View of Stigma Experienced by Lone Parents in Irish Homeless and Employment Services
Authors: Finn Philip , Murphy Mary P
Published: April 2022

This critical and empirical article explores contemporary reproduction, experience, and responses to stigma in welfare delivery in Ireland. Combining qualitative data about lone parents (n22) gathered through two different research projects in 2017 and 2018 allows us to interrogate stigma in a multi-dimensional way and as an overarching experience as an ongoing project of neo liberalism. We analyse our findings using Baumberg’s (2016) typology of stigma which differentiates claim making stigma from personal and societal stigma, applying the framework to empirical data concerning lone parents’ recent experiences of Irish labour activation and homeless support services. We find that while behavioural conditionality necessarily frames this experience and constrains claimants, it is not totalising. We conclude by using Tyler’s concept of stigmacraft to situate the context of stigma as part of the political economy of welfare.
Covid-19 and the Crisis in Social Care: Exploring the Experiences of Disabled People in the Pandemic
Authors: Pearson Charlotte , Watson Nick , Brunner Richard , Cullingworth Jane , Hameed Shaffa , Scherer Nathaniel , Shakespeare Tom
Published: April 2022

Governments across the world have been slow in reacting to meeting the needs of disabled people during the pandemic. This has exposed existing inequalities in social policies, as well as new support barriers. Debates over social care have focused on Covid-19's impact on those living in residential care. Little is known about the experiences of disabled people who rely on daily support in their homes.

This article reports on a year-long study examining the experiences of disabled people during the pandemic in England and Scotland. It focuses on the crisis in social care and offers evidence of how lives have been disrupted. For many, this resulted in a sudden loss of services, delayed assessments and break down of routines and communities. Findings underline the weakness of social care in its wider relationship with the NHS and show how the social care crisis has challenged the goal of independent living.
Support for Domestic Islamist Terrorism in Bangladesh: Insights from a Novel Survey
Authors: Fair C. Christine , Patel Parina
Published: April 2022

We employ regression analysis of 2017 survey data from 4,067 Bangladeshis to exposit the lineaments of individual support for domestic Islamist violence. Our dependent variables derive from measures of public support for the stated goals and violent means of three Bangladeshi Islamist terrorist groups. Our study variables include participation in communal Friday prayer; indexed measures of other pietic practices; preferences for Shari'a and secularism; and gender. We include several well-established control variables. We find that participation in communal Friday prayers significantly correlates with diminished support for militant groups while having no effect upon support for their violent means. In four (of 10) models, we find that respondents who view Shari'a as being coterminous with scriptural literalism and harsh physical punishments are significantly more likely to support the groups' goals. Finally, we find women to be consistently more likely to support the goals and means of the militant groups.
A Ka-band high-isolation waveguide power divider with planar output ports and out-of-phase
Authors: Tang Cong , Gao Xin , Zhu Hongquan , Zhang Jinrong
Published: April 2022

A waveguide power divider based on ridge waveguide to microstrip line transition is presented in this paper. To improve the isolation performance, a probe insulator is inserted into the contact face from the center of the waveguide side wall, also two chip resistors are mounted on a planar substrate and connected with the probe to absorb the coupled energy. The impedance transformation is accomplished by ridge waveguide to microstrip line transition, which is hidden in the waveguide. This proposed power divider shows merits of waveguide power dividers and substrate-integrated waveguide power dividers simultaneously, i.e. planar output ports, compact size, and high isolation. For verification, a power divider operating at the Ka-band is simulated, fabricated, and measured. The obtained results show the return loss and isolation are better than 10 and 20 dB, respectively. The measured insertion loss is <1.5 dB, including the insertion loss of waveguide to microstrip line transitions at the output port in the range of 34.6–39 GHz.
Social Adversity Reduces Polygenic Score Expressivity for General Cognitive Ability, but Not Height
Authors: Peñaherrera-Aguirre Mateo , Woodley Michael A. , Sarraf Matthew A. , Beaver Kevin M.
Published: April 2022

It has been hypothesized that even ‘perfect’ polygenic scores (PGSs) composed of only causal variants may not be fully portable between different social groups owing to gene-by-environment interactions modifying the expression of relevant variants. The impacts of such interactions involving two forms of social adversity (low socioeconomic status [SES] and discrimination) are examined in relation to the expressivity of a PGS for educational attainment composed of putatively causal variants in a large, representatively sampled and genotyped cohort of US children. A relatively small-magnitude Scarr–Rowe effect is present (SES × PGSEDU predicting General Cognitive Ability [GCA]; sR = .02, 95% CI [.00, .04]), as is a distinct discrimination × PGSEDU interaction predicting GCA (sR = −.02, 95% CI [−.05, 00]). Both are independent of the confounding main effects of 10 ancestral principal components, PGSEDU, SES, discrimination and interactions among these factors. No sex differences were found. These interactions were examined in relation to phenotypic and genotypic data on height, a prospectively more socially neutral trait. They were absent in both cases. The discrimination × PGSEDU interaction is a co-moderator of the differences posited in modern versions of Spearman’s hypothesis (along with shared environmentality), lending support to certain environmental explanations of those differences. Behavior-genetic analysis of self-reported discrimination indicates that it is nonsignificantly heritable (h2 = .027, 95% CI [−.05, .10]), meaning that it is not merely proxying some underlying source of heritable phenotypic variability. This suggests that experiences of discrimination might stem instead from the action of purely social forces.
The Role of Regional Connections in Planning for Future Power System Operations Under Climate Extremes

Published: April 2022

Identifying the sensitivity of future power systems to climate extremes must consider the concurrent effects of changing climate and evolving power systems. We investigated the sensitivity of a Western U.S. power system to isolated and combined heat and drought when it has low (5%) and moderate (31%) variable renewable energy shares, representing historic and future systems. We used an electricity operational model combined with a model of historically extreme drought (for hydropower and freshwater‐reliant thermoelectric generators) over the Western U.S. and a synthetic, regionally extreme heat event in Southern California (for thermoelectric generators and electricity load). We found that the drought has the highest impact on summertime production cost (+10% to +12%), while temperature‐based deratings have minimal effect (at most +1%). The Southern California heat wave scenario impacting load increases summertime regional net imports to Southern California by 10–14%, while the drought decreases them by 6–12%. Combined heat and drought conditions have a moderate effect on imports to Southern California (−2%) in the historic system and a stronger effect (+8%) in the future system. Southern California dependence on other regions decreases in the summertime with the moderate increase in variable renewable energy (−34% imports), but hourly peak regional imports are maintained under those infrastructure changes. By combining synthetic and historically driven conditions to test two infrastructures, we consolidate the importance of considering compounded heat wave and drought in planning studies and suggest that region‐to‐region energy transfers during peak periods are key to optimal operations under climate extremes.
Natural Variations in Dissolved Silicon Isotopes Across the Arctic Ocean From the Pacific to the Atlantic
Authors: Giesbrecht Karina E. , Varela Diana E. , de Souza Gregory F. , Maden Colin
Published: April 2022

We present measurements of the silicon isotopic composition of silicic acid (δ30Si‐Si(OH)4) from seawater collected along a transect following one of the main flow paths of Pacific‐origin waters through the Arctic Ocean during the Canadian Arctic GEOTRACES and Distributed Biological Observatory expeditions in the summer of 2015. The δ30Si‐Si(OH)4signals track the modification of Pacific‐origin waters as they transit from west to east, and reflect the distribution of water masses, the dissolution of biogenic silica (bSiO2), and the biological utilization of Si in surface waters. Pacific‐origin waters have lower δ30Si‐Si(OH)4values than the surrounding water masses and are closely linked with a tongue of nutrient‐rich cold water that can be traced back to the Bering Strait. The δ30Si‐Si(OH)4measurements indicate that the high [Si(OH)4] in the deep waters of Baffin Bay are driven entirely by dissolution of exported bSiO2. Using an open‐system model, we estimate the biogenic Si isotope effect (30ε) for the Bering and Chukchi Seas, and the Canadian Arctic Archipelago to be30ε = −1.18 ± 0.02‰ (1SE), which agrees very well with laboratory and field estimates. In contrast, the isotope systematics in the Canada Basin and Baffin Bay are better represented by a closed‐system model. We also present an approach to estimate production by sea‐ice algae using δ30Si‐Si(OH)4signals, though a better understanding of the sea‐ice/water column Si systematics in the Arctic is needed to confirm the viability of this approach.
Global Controls on DOC Reaction Versus Export in Watersheds: A Damköhler Number Analysis
Authors: Liu Shaoda , Maavara Taylor , Brinkerhoff Craig B. , Raymond Peter A.
Published: April 2022

The relative capacity for watersheds to eliminate or export reactive constituents has important implications on aquatic ecosystem ecology and biogeochemistry. Removal efficiency depends on factors that affect either the reactivity or advection of a constituent within river networks. Here, we characterized Damköhler number (Da) for dissolved organic carbon (DOC) uptake in global river networks. Da equals the advection to reaction timescale ratio and thus provides a unitless indicator for DOC reaction intensity during transport within river networks. We aim to demonstrate the spatial and temporal patterns and interplays among factors that determine DOC uptake across global river networks. We show that watershed size imposes a primary control on river network DOC uptake due to a three orders of magnitude difference in water residence time (WRT) between the smallest and largest river networks. DOC uptake capacity in tropical river networks is 2–6 times that in temperate and the Arctic river networks, coinciding with larger DOC removals in warm than in cold watersheds. River damming has a profound impact on DOC uptake due to significantly extended WRTs, particularly in temperate watersheds where most constructed dams are situated. Global warming is projected to increase river network DOC uptake by ca. 19% until year 2100 under the RCP4.5 scenario.
Diurnal Thermally Driven Cross‐Shore Exchange in Steady Alongshore Currents
Authors: Safaie Aryan , Pawlak Geno , Davis Kristen A.
Published: April 2022

Idealized numerical modeling of thermally driven baroclinic exchange is performed to understand how cross‐shore flow is modulated by steady alongshore currents and associated shear‐generated turbulence. In general, we find that shear‐driven vertical mixing reduces the temperature gradients responsible for establishing the baroclinic flow, such that cross‐shore thermal exchange diminishes with alongshore current speed. Circulation in a base‐case simulation of thermal exchange with no alongshore forcing contains a cooling response consisting of a midday flow in the form of a downslope current with a compensating onshore near‐surface flow driving cross‐shore exchange, followed by an afternoon warming response flow via an offshore‐directed surface warm front, with a compensating return flow at the bottom. Nighttime convective cooling enhances vertical mixing and decelerates the warming response, and the diurnal cycle is renewed. In this base‐case scenario, representative of tropical reef environments with optically clear water and weak alongshore flow, surface heating and cooling can drive cross‐shore circulation with O(1) cm s−1 velocities. Alongshore flow forcing is implemented to induce upwelling‐ and downwelling‐favorable cross‐shore circulation. For mild alongshore forcing, the baroclinic cross‐shore exchange flow is enhanced due to an increase in the horizontal temperature gradient. Stronger alongshore flow leads to diminished thermally driven exchange, ultimately reaching a regime where the cross‐shore exchange is due predominantly to Ekman dynamics. Though exchange velocities are relatively small (O(1) cm s−1), these persistent exchange flows are capable of flushing the nearshore region multiple times per day, with important implications for water properties of nearshore ecosystems.
Modeling the Hydrologic Influence of Subsurface Tile Drainage Using the National Water Model
Authors: Valayamkunnath Prasanth , Gochis David J. , Chen Fei , Barlage Michael , Franz Kristie J.
Published: April 2022

Subsurface tile drainage (TD) is a dominant agriculture water management practice in the United States (US) to enhance crop production in poorly drained soils. Assessments of field‐level or watershed‐level (<50 km2) hydrologic impacts of TD are becoming common; however, a major gap exists in our understanding of regional (>105 km2) impacts of TD on hydrology. The National Water Model (NWM) is a distributed 1‐km resolution hydrological model designed to provide accurate streamflow forecasts at 2.7 million reaches across the US. The current NWM lacks TD representation which adds considerable uncertainty to streamflow forecasts in heavily tile‐drained areas. In this study, we quantify the performance of the NWM with a newly incorporated tile‐drainage scheme over the heavily tile‐drained Midwestern US. Employing a TD scheme enhanced the uncalibrated NWM performance by about 20–50% of the fully calibrated NWM (Calib). The calibrated NWM with tile drainage (CalibTD) showed enhanced accuracy with higher event hit rates and lower false alarm rates than Calib. CalibTD showed better performance in high‐flow estimations as TD increased streamflow peaks (14%), volume (2.3%), and baseflow (11%). Regional water balance analysis indicated that TD significantly reduced surface runoff (−7% to −29%), groundwater recharge (−43% to −50%), evapotranspiration (−7% to −13%), and soil moisture content (−2% to −3%). However, TD significantly increased soil profile lateral flow (27.7%) along with infiltration and soil water storage potential. Overall, our findings highlight the importance of incorporating the TD process into the operational configuration of the NWM.
Crafting Spaces for Good Water Governance in Pakistan

Published: April 2022

The most significant investment in improved water governance for Pakistan in recent decades—irrigation management transfer under the PIDA Act of 1997—ended with repeal in 2019 in the province of Punjab. Before embarking on the next major experiment, we wish to examine what the opportunity space for improvement in Pakistan’s water governance is. We develop a conceptual model that maps the roles of hydrology, infrastructure, management, governance, and learning in shaping water supply. We are motivated by the overarching question of where the best opportunities to improve water governance in Pakistan lie, and suggest in our analysis that the hydraulic constraints of the Indus Basin Irrigation System (IBIS) that have previously been the basis for consideration of scale in water (irrigation) governance are inappropriate. Our key recommendation is instead to identify the key “problemsheds” for the IBIS as a vehicle for identifying scales of intervention and communities of common water interest (possibly at village, union, or tehsil administrative levels) that can allow irrigators to transcend the rigid hydraulic user groupings that irrigation channels impose, and contribute more meaningfully to good local water governance.
A batch microfabrication of a self-cleaning, ultradurable electrochemical sensor employing a BDD film for the online monitoring of free chlorine in tap water

Published: April 2022

Free chlorine is one of the key water quality parameters in tap water. However, a free chlorine sensor with the characteristics of batch processing, durability, antibiofouling/antiorganic passivation and in situ monitoring of free chlorine in tap water continues to be a challenging issue. In this paper, a novel silicon-based electrochemical sensor for free chlorine that can self-clean and be mass produced via microfabrication technique/MEMS (Micro-Electro-Mechanical System) is proposed. A liquid-conjugated Ag/AgCl reference electrode is fabricated, and electrochemically stable BDD/Pt is employed as the working/counter electrode to verify the effectiveness of the as-fabricated sensor for free chlorine detection. The sensor demonstrates an acceptable limit of detection (0.056 mg/L) and desirable linearity (R2 = 0.998). Particularly, at a potential of +2.5 V, hydroxyl radicals are generated on the BBD electrode by electrolyzing water, which then remove the organic matter attached to the surface of the sensor though an electrochemical digestion process. The performance of the fouled sensor recovers from 50.2 to 94.1% compared with the initial state after self-cleaning for 30 min. In addition, by employing the MEMS technique, favorable response consistency and high reproducibility (RSD < 4.05%) are observed, offering the opportunity to mass produce the proposed sensor in the future. A desirable linear dependency between the pH, temperature, and flow rate and the detection of free chlorine is observed, ensuring the accuracy of the sensor with any hydrologic parameter. The interesting sensing and self-cleaning behavior of the as-proposed sensor indicate that this study of the mass production of free chlorine sensors by MEMS is successful in developing a competitive device for the online monitoring of free chlorine in tap water.
A deep learning-based hybrid model of global terrestrial evaporation
Authors: Koppa Akash , Rains Dominik , Hulsman Petra , Poyatos Rafael , Miralles Diego G.
Published: April 2022

Terrestrial evaporation (E) is a key climatic variable that is controlled by a plethora of environmental factors. The constraints that modulate the evaporation from plant leaves (or transpiration, Et) are particularly complex, yet are often assumed to interact linearly in global models due to our limited knowledge based on local studies. Here, we train deep learning algorithms using eddy covariance and sap flow data together with satellite observations, aiming to model transpiration stress (St), i.e., the reduction of Et from its theoretical maximum. Then, we embed the new St formulation within a process-based model of E to yield a global hybrid E model. In this hybrid model, the St formulation is bidirectionally coupled to the host model at daily timescales. Comparisons against in situ data and satellite-based proxies demonstrate an enhanced ability to estimate St and E globally. The proposed framework may be extended to improve the estimation of E in Earth System Models and enhance our understanding of this crucial climatic variable.
The influence of light path length on the color of synthetic ruby
Authors: Yuan Bin , Guo Ying , Liu Ziyuan
Published: April 2022

The corrected ultraviolet–visible light spectrum was used to calculate the color of synthetic rubies with different light path lengths, and the influence of light path length and standard light source on the color of synthetic ruby was studied. The results show that the difference in colour between the o light direction and the e light direction of the synthetic ruby decreases as the length of the light path increases. At the same time, as the length of the light path increases, the lightness L* decreases, and the hue angle h° increases. The chroma C* first increases as the length of the light path increases, and then begins to decrease under the influence of the continuous decrease in lightness. The color difference ΔE*abreaches the maximum when the light path length is around 10 mm, and the standard light source has the greatest influence on the color difference ΔE*ab. As the length of the light path continues to increase, the influence of the standard light source on the color difference ΔE*abdecreases. In the ultraviolet–visible light spectrum, the strong absorption band of Cr3+at 545 nm is the main cause of the color of the ruby. The larger the area of the band at 545 nm, the lower the lightness and the higher the hue angle, which means the ruby colour is redder.

To explore the demographic profiling, causes, types, complications, management outcomes, and severity of fireworks-inflicted ocular injuries in children in KSA. This is a retrospective study of 115 cases with eye injuries managed at the Emergency Department, of our institution between 2003 and 2019. Demography, clinical features at presentation, mode of management and the Best-corrected visual acuity (BCVA) were evaluated at the last follow up. The study included 117 eyes of 115 children [median age: 9 years; 96 (83.5%) boys;19 (16.5%) girls]. Fifty-six (48.7%) participants were bystanders. The injuries were caused mainly due to bangers (n = 47; 40.9%), rockets in bottle (n = 28; 24.3%), firecrackers (n = 27; 23.5%), and nonspecific reasons (n = 13; 11.3%). The children had presented with various severity levels: corneal abrasion (n = 52; 44.4%); cataract (n = 47;40.2%); penetrating injury (n = 40; 34.2%); secondary glaucoma (n = 22;18.8%); subluxated lens (n = 19;16.2%); limbal stem cell deficiency (n = 14;12.0%); Iridodialysis (n = 12;10.3%), and vitreous hemorrhage (n = 11;9.4%). Management interventions of the eyes under study included: penetrating injury repair (n = 40; 34.2%), lens removal plus intraocular lens implantation (n = 26; 22.2%), removal of foreign body (n = 9; 7.7%). The BCVA after six months was 20/20 to 20/60 in 49 (41%) cases; 20/70 to 20/200 in 27 (23.1%) cases; < 20/200 to 20/400 in 7 (6%) cases, and < 20/400 in 34 (29.1%) of the cases. Out of 51.3% eyes with < 20/200 before management, only 35% recorded severe visual impairment. Fireworks-related eye injuries were mainly observed in boys primarily due to the use of bangers. Visual disability remained in one-third of the managed cases.

The compound extreme weather event that impacted northern Queensland in February 2019 featured record-breaking rainfall, persistent high wind gusts and relatively cold day-time temperatures. This caused livestock losses numbering around 500,000 in the northwest Queensland Gulf region. In this study, we examine the livestock chill conditions associated with this week-long compound weather event and its potential for prediction from eleven world-leading sub-seasonal to seasonal (S2S) forecast systems. The livestock chill index combines daily rainfall, wind and surface temperature data. Averaged over the event week, the potential heat loss of livestock was in the moderate to high category, with severe conditions on the day of peak rainfall (5 February). Using calibrated forecasts from the Bureau of Meteorology's S2S forecast system, ACCESS-S1, a 1-week lead prediction showed a 20–30% probability of extreme livestock chill conditions over the northwest Queensland Gulf region, however the highest probabilities were located to the west of where the greatest livestock impacts were observed. Of the remaining ten S2S systems, around half predicted a more than 20% chance of extreme conditions, more than twice the climatological probability. It appears that the prediction accuracy arose from the skilful forecasts of extreme rainfall, as opposed to cold day-time temperature and strong wind forecasts. Despite a clear association between the observed extreme weather conditions and an active Madden–Julian Oscillation (MJO) event stalling in the western Pacific, the majority of 1-week lead S2S forecasts showed little indication of a slow-down in the MJO. As the livestock chill index was developed for southern Australian sheep, it may not be the best metric to represent the effects of exposure on tropical cattle breeds. Hence, this study draws attention to the need for tailored diagnostics that better represent the cold effects of summer tropical cyclones and tropical depressions on northern Australian livestock.

The apicomplexan parasiteCystoisospora suisis an enteropathogen of suckling piglets with woldwide distribution. As with all coccidian parasites, its lifecycle is characterized by asexual multiplication followed by sexual development with two morphologically distinct cell types that presumably fuse to form a zygote from which the oocyst arises. However, knowledge of the sexual development ofC. suisis still limited. To complement previous in vitro studies, we analysed transcriptional profiles at three different time points of development (corresponding to asexual, immature and mature sexual stages) in vitro via RNASeq.Overall, transcription of genes encoding proteins with important roles in gametes biology, oocyst wall biosynthesis, DNA replication and axonema formation as well as proteins with important roles in merozoite biology was identified. A homologue of an oocyst wall tyrosine rich protein ofToxoplasma gondiiwas expressed in macrogametes and oocysts ofC. suis. We evaluated inhibition of sexual development in a host-free culture forC. suisby antiserum specific to this protein to evaluate whether it could be exploited as a candidate for control strategies againstC. suis. Based on these data, targets can be defined for future strategies to interrupt parasite transmission during sexual development.

Fine needle aspiration biopsy is a crucial method for preoperative diagnosis of thyroid nodules. However, thyroid nodules classified as Bethesda categories III–V cannot obtain definite cytological results. Our aim was to study the diagnostic value of thyroid imaging reporting and data system combined with BRAFV600E mutation analysis in Bethesda categories III–V thyroid nodules, so as to provide more precise direction for the follow-up treatments. A total of 174 Bethesda categories III–V thyroid nodules performed TIRADS and BRAFV600E mutation analysis were included in the study. We retrospectively analyzed the ultrasound features as well as the results of BRAFV600E mutation of the 174 thyroid nodules. In the multiple regression analysis models, ultrasound features including lobulated or irregular margin, punctate echogenic foci, and shape with taller-than-wide were statistically significant in malignant nodules (p < 0.05). The area under the curve of the combination of TIRADS and BRAFV600E increased to 0.925, which were much higher than TIRADS (0.861) and BRAFV600E (0.804) separately. Combined diagnosis was of the greatest value to identify Bethesda III–V thyroid nodules definitely, especially with higher sensitivity (93%) and accuracy (90%).

Published: April 2022

Optical metasurfaces are researched more and more intensively for the possible realization of lightweight and compact optical devices with novel functionalities. In this paper, a new beam-steering system based on double metasurface lenses (metalenses) is proposed and developed. The proposed system is lightweight, small volume, low cost, and easy to integrate. The exact close-form forward and numerical inverse solutions are derived respectively using the generalized Snell’s law of refraction. Given the orientations of the double metalenses, the pointing position can be accurately determined. If the desired pointing position is given, the required metalenses’ orientations can be obtained by applied global optimization algorithms to solve nonlinear equations related to the inverse problem. The relationships of the scan region and blind zone with the system parameters are derived. The method to eliminate the blind zone is given. Comparison with double Risley-prism systems is also conducted. This work provides a new approach to control light beams.
