Published: March 2022

Abstract
The convection–diffusion process of carbon dioxide (CO2) dissolution in a saline reservoir is investigated to shed light on the effects of the permeability heterogeneity. Using sequential Gaussian simulation method, random permeability fields in two and three-dimension (2D and 3D) structures are generated. Quantitative (average amount of the dissolved CO2 and dissolution flux) and qualitative (pattern of the dissolved CO2 and velocity streamlines) measurements are used to investigate the results. A 3D structure shows a slightly higher dissolution flux than a 2D structure in the homogeneous condition. Results in the random permeability fields in 2D indicates an increase in the standard deviation of the permeability nodes enhances the dissolution efficiency, fluctuations in CO2 dissolution flux, separation between the different realizations from the same input parameters, and tendency toward more jagged convective fingers’ shape. Furthermore, the distance between the permeability nodes increases the convective fingers’ dissolution efficiency and jagged structure. The degree of freedom in 3D structures results in a higher chance of escaping from the low permeability zones and reduces the interactions between convective fingers in 3D systems. With the same variance and correlation length between permeability nodes, connectivity between high permeable zones in 3D cases are less than that of 2D cases; therefore, 2D realizations overestimate the dissolution flux of real heterogeneous 3D structures, which should be considered carefully.

Article Highlights

3DWoodWind: robotic winding processes for material-efficient lightweight veneer components
Authors: Göbert Andreas , Deetman Arjen , Rossi Andrea , Weyhe Ole , Eversmann Philipp 
Published: March 2022

AbstractWinding processes are known from fiber composite technology for highly resistance lightweight components for aviation. These fiber-based processes work predominantly with synthetic composites made of carbon or glass fibers. For the construction industry, these additive processes are very promising and resource-efficient building processes, but they are still hardly used in timber construction despite the very high level of digitalization and technical development. The 3DWoodWind research project uses a continuous strip of thin veneer as a sustainable alternative as its application material. Its natural fibers are intact, continuous, and tensile. In the project, three-dimensional winding processes were developed for material-efficient hollow profile lightweight components made of wood. We describe the material system, composed of suitable combinations of veneers and adhesives, and develop computational design methods for filament layout and robotic fabrication methods. We also show an open-source prototype development method, necessary for efficient prototyping. Through several fabrication case studies, we demonstrate the capabilities of the production process, and investigate suitable architectural applications. These hollow lightweight components could save large amounts of material in timber construction and serve as a substitute for concrete or steel components in the future. We conclude by discussing possible applications in the construction industry and future research possibilities.

AbstractIndustrial equipment/machinery is an important element of manufacturing. They are used for producing objects that people need for everyday use. Therefore, there is a challenge to adopt effective maintenance strategies to keep them well-functioning and well-maintained in production lines. This will save energy and materials and contribute genuinely to the circular economy and creating value. Remanufacturing or refurbishment is one of the strategies to extend life of such industrial equipment. The paper presents an initial framework of cost estimation model based on combination of activity-based costing (ABC) and human expertise to assist the decision-making on best life extension strategy (e.g. remanufacturing, refurbishment, repair) for industrial equipment. Firstly, ABC cost model is developed to calculate cost of life extension strategy to be used as a benchmark strategy. Next, expert opinions are employed to modify data of benchmark strategy, which is then used to estimate costs of other life extension strategies. The developed cost model has been implemented in VBA-based Excel® platform. A case study with application examples has been used to demonstrate the results of the initial cost model developed and its applicability in estimating and analysing cost of applying life extension strategy for industrial equipment. Finally, conclusions on the developed cost model have been reported.
Lower limb muscle performance during a closed chain single leg squat and a squat jump in people with leg weakness after stroke: A comparative study
Authors: Tolé Genevieve , Williams Gavin , Holland Anne E. , Clark Ross A. 
Published: March 2022

Abstract

Objective:
To determine if the intention to perform an exercise at speed leads to beneficial alterations in kinematic and kinetic components of the movement in people with post-stroke hemiplegia.

Design:
Comparative study.

Setting:
Subacute metropolitan rehabilitation hospital.

Participants:
Convenience sample of patients admitted as an inpatient or outpatient with a diagnosis of stroke with lower limb weakness, functional ambulation category score ≥3, and ability to walk ≥14metres.

Methods:
Participants performed a single leg squat exercise on their paretic and nonparetic legs on a leg sled under three conditions: 1) self-selected speed (SS), 2) fast speed (FS), 3) jump squat (JS). Measures of displacement, flight time, peak concentric velocity, and muscle excitation (via electromyography) were compared between legs and conditions.

Results:
Eleven participants (age: 56 ± 17 years; median time since stroke onset: 3.3 [IQR 3,41] months) were tested. All participants achieved a jump during the JS, as measured by displacement and flight time respectively, on both their paretic (0.25 ± 0.16 m and 0.42 ± 0.18 s) and nonparetic (0.49 ± 0.36 m and 0.73 ± 0.28 s) legs; however it was significantly lower on the non-paretic leg (p < 0.05). Peak concentric velocity increased concordantly with intended movement speed (JS-FS paretic: 0.96 m/s, non-paretic: 0.54 m/s; FS-SS paretic 0.69 m/s, nonparetic 0.38 m/s; JS-SS paretic 1.66 m/s, non-paretic 0.92 m/s). Similarly, muscle excitation increased significantly (p < 0.05) with faster speed for the paretic and nonparetic vastus lateralis. For gastrocnemius, the only significant difference was an increase during nonparetic JS vs. SS and FS.

Conclusions:
Speed affects the kinematic and kinetic components of the movement. Performing exercises ballistically may improve training outcomes for people post-stroke.
Surviving But Not Thriving: VOX and Spain in Times of COVID-19
Authors: Zanotti Lisa , Turnbull-Dugarte Stuart James 
Published: March 2022

AbstractIn this article, we triangulate qualitative data regarding the framing of the pandemic and the strategic decisions taken by Spain's new populist radical right-wing party, VOX, with a quantitative analysis of aggregate polling data and individual-level survey responses to answer three questions: how has VOX framed the politics of the pandemic? What actions has VOX taken in response to COVID-19? Have the events of the COVID-19 crisis affected VOX's electoral chances? We argue that VOX's response to the pandemic has focused on augmenting the antagonistic relationship between itself and the political establishment, especially the left-wing government. Strategically, VOX has sought to leverage the health crisis to engage in legislative manoeuvres aiming, without success, to position itself as the primary party-in-waiting for right-wing voters. We also demonstrate that VOX has proven to be resilient against the potential for electoral decline that was widely prophesied at the beginning of the pandemic.

Published: March 2022

AbstractBackground:Spinal fusion surgery (SFS) is one of the most common operations in the United States, >450,000 SFSs are performed annually, incurring annual costs >$10 billion.Objectives:We used a nationwide longitudinal database to accurately assess incidence and payments associated with management of postoperative infection following SFS.Methods:We conducted a retrospective, observational cohort analysis of 210,019 patients undergoing SFS from 2014 to 2018 using IBM MarketScan commercial and Medicaid–Medicare databases. We assessed rates of superficial/deep incisional SSIs, from 3 to 180 days after surgery using Cox proportional hazard regression models. To evaluate adjusted payments for patients with/without SSIs, adjusted for inflation to 2019 Consumer Price Index, we used generalized linear regression models with log-link and γ distribution.Results:Overall, 6.6% of patients experienced an SSI, 1.7% superficial SSIs and 4.9% deep-incisional SSIs, with a median of 44 days to presentation for superficial SSIs and 28 days for deep-incisional SSIs. Selective risk factors included surgical approach, admission type, payer, and higher comorbidity score. Postoperative incremental commercial payments for patients with superficial SSI were $20,800 at 6 months, $26,937 at 12 months, and $32,821 at 24 months; incremental payments for patients with deep-incisional SSI were $59,766 at 6 months, $74,875 at 12 months, and $93,741 at 24 months. Corresponding incremental Medicare payments for patients with superficial incisional at 6, 12, 24-months were $11,044, $17,967, and $24,096; while payments for patients with deep-infection were: $48,662, $53,757, and $73,803 at 6, 12, 24-months.Conclusions:We identified a 4.9% rate of deep infection following SFS, with substantial payer burden. The findings suggest that the implementation of robust evidence-based surgical-care bundles to mitigate postoperative SFS infection is warranted.
A new marrellomorph arthropod from southern Ontario: a rare case of soft-tissue preservation on a Late Ordovician open marine shelf
Authors: Moysiuk Joseph , Izquierdo-López Alejandro , Kampouris George E. , Caron Jean-Bernard 
Published: March 2022

AbstractOrdovician open marine Lagerstätten are relatively rare and widely dispersed, producing a patchy picture of the diversity and biogeography of nonmineralized marine organisms and challenging our understanding of the fate of Cambrian groups. Here, for the first time, we report soft-bodied fossils, including a well-preserved marrellomorph arthropod, fragmentary carapaces, and macroalgae, from the Late Ordovician (Katian) Upper Member of the Kirkfield Formation near Brechin, Ontario. The unmineralized elements and associated exceptionally preserved shelly biota were entombed rapidly in storm deposits that smothered the shallow, carbonate-dominated shelf. The marrellomorph, Tomlinsonus dimitrii n. gen. n. sp., is remarkable for its ornate, curving cephalic spines and pair of hypertrophied appendages, suggesting a slow-moving, benthic lifestyle. Reevaluation of marrellomorph phylogeny using new data favors an arachnomorph affinity, although internal relationships are robust to differing outgroup selection. Clades Marrellida and Acercostraca are recovered, but the monophyly of Marrellomorpha is uncertain. The new taxon is recovered as sister to the Devonian Mimetaster and, as the second-youngest known marrellid, bridges an important gap in the evolution of this clade. More generally, the Brechin biota represents a rare window into Ordovician open marine shelf environments in Laurentia, representing an important point of comparison with contemporaneous Lagerstätten from other paleocontinents, with great potential for further discoveries.UUID: http://zoobank.org/884589d0-08f7-4398-ab42-1f5d459be9e9
On large-deviation probabilities for the empirical distribution of branching random walks with heavy tails
Authors: Zhang Shuxiong 
Published: March 2022

AbstractGiven a branching random walk
$(Z_n)_{n\geq0}$
on
$\mathbb{R}$
, let
$Z_n(A)$
be the number of particles located in interval A at generation n. It is well known that under some mild conditions,
$Z_n(\sqrt nA)/Z_n(\mathbb{R})$
converges almost surely to
$\nu(A)$
as
$n\rightarrow\infty$
, where
$\nu$
is the standard Gaussian measure. We investigate its large-deviation probabilities under the condition that the step size or offspring law has a heavy tail, i.e. a decay rate of
$\mathbb{P}(Z_n(\sqrt nA)/Z_n(\mathbb{R})>p)$
as
$n\rightarrow\infty$
, where
$p\in(\nu(A),1)$
. Our results complete those in Chen and He (2019) and Louidor and Perkins (2015).
Does accommodation work? Mainstream party strategies and the success of radical right parties
Authors: Krause Werner , Cohen Denis , Abou-Chadi Tarik 
Published: March 2022

AbstractThis research note investigates how mainstream party strategies affect the success of radical right parties (RRPs). It is a widespread view that mainstream party accommodation of radical right core issue positions would reduce the radical right's success. Empirical evidence for this claim, however, remains inconclusive. Using party level data as well as micro-level voter transitions between mainstream and RRPs, we re-evaluate the effectiveness of accommodative strategies and also test whether they work contingent on specific conditions, e.g., the newness of radical right challengers or the existence of a cordon sanitaire. We do not find any evidence that accommodative strategies reduce radical right support. If anything, our results suggest that they lead to more voters defecting to the radical right. Our findings have important implications for the study of multi-party competition as they challenge what has become a core assumption of this literature: that accommodative strategies reduce niche party success.
Signposts for an Eastern Orthodox inclusive anthropological ethics
Authors: Maican Petre 
Published: March 2022

AbstractDespite the strong interest of Eastern Orthodox theologians in the area of anthropology, their reflection has almost never included intellectual disability. The article aims to take the discussion further by providing the contours of an inclusive anthropological ethics. In this sense, it will develop constructively the three main principles of Dumitru Stăniloae's dialogical anthropology: (1) that each human being is a person because she is called to dialogue with God from the womb of her mother; (2) that this dialogue with God is mediated by one's neighbour; (3) that the materiality of creation is meant to be transformed into a gift of communion with other humans and God.
Democratization and the Practices of Voting in Habsburg Austria, 1896–1914: New Directions in Research
Authors: Bader-Zaar Birgitta 
Published: March 2022

AbstractFrom the mid-1890s, Habsburg Austria began to follow European trends and experienced a gradual democratization of voting rights, which involved not only an expansion of the electorate but also an innovation of procedures that attempted to modernize elections. In this context, the article calls for a more systematic study of voting practices and attempts to point at some issues that have thus far received insufficient analysis. These include not only the occasional massive violent conflicts at elections that could accompany democratization until World War I but also the presence of women as voters at local and diet elections and the gradual introduction of polling booths. Measures such as allowing single women to cast their vote personally in a few crownlands or attempting to guard the secrecy of the vote suggest the level of experimentation in this period. The state's objective of orderly, “modern” elections is particularly called into question when we consider the extent to which government agents, including policemen and the army, were involved in election conflicts that resulted in fraud and sometimes bloodshed.
Distribution and community structure of fish in relation with water physico-chemical parameters of floodplain rivers in the Alitash National Park, Ethiopia
Authors: Eyayu Alamrew , Getahun Abebe 
Published: March 2022

AbstractRiverine ecosystems are highly exposed to different forms of human activities and fish distribution in such habitats can be affected by different features of water. Tributaries of the Abbay and Tekeze Basins are supporting all life requesting activities in Ethiopia. Fisheries of these habitats are also the mainstay of livelihoods. However, brutal human activities are affecting these ecosystems and the fish therein. This study was thus undertaken to examine fish distribution and community structure in relation to water parameters in Ayima, Gelegu and Shinfa Rivers. 2719 fish specimens identified into 43 species were sampled using gillnets, cast nets and electro-fishing on a seasonal campaign. Based on frequency of occurrence (%FO), 5 species fell in the category of ‘euconstant occurrence’ or their FO was ≥75%, while many species were laid in the ‘constant occurrence’. Among others, site depth, total phosphorus, dissolved oxygen and river channel diameter were key environmental factors determining fish community structure. Similarity percentage produced an overall average Bray-Curtis dissimilarity of 60.8% between the fish communities of the three rivers. The final model accounted for 77.2% of the total variance in fish composition, and all canonical axes were significant (Monte Carlo test 499, p = 0.002). Generally, this study was conducted in areas where no ecological studies are undertaken and the results obtained from this study could be important for sustainable utilization of Ethiopian fisheries.

Published: March 2022

AbstractKONAR-MultifunctionalTM VSD Occluder (Lifetech, Shenzhen, China) is one of the most recent additions to the armamentarium of device closure interventions offering special features to tackle complex cardiac anatomies. Herein, we report the first use of the KONAR-MFO in an 8.5-year-old female patient (27 kg/129 cm) with stage III palliated univentricular heart to close an acquired post-operative tunnel-like communication (5 mm long × 2.6 mm large) between the right anterior non-coronary aortic sinus and the rudimentary right ventricular cavity. The shunt was diagnosed two and a half years after bulboventricular foramen surgical enlargement. The 5× 3 mm KONAR-MFO was retrogradely implanted under ultrasound and biplane fluoroscopic guidance. Immediate and 12-month follow-up confirmed successful outcomes with complete shunt closure and preserved aortic valve competence.
Harnessing the Power of Structural Oncology
Authors: Solares Maria J. , Kelly Deborah F. 
Published: March 2022

Abstract:Microscopy has evolved through centuries of desire to see the unseen world. Modern technologies have pushed the limits of what's possible, inspiring the field of structural biology. Coupled with advances in biochemistry, scientists can now study the fine details of tiny intruders in the body as well as the molecular culprits of disease. Despite these monumental achievements, human health still suffers from persistent dysfunctions in biological molecules. Through cryo-electron microscopy (cryo-EM) imaging technology we can create more translatable models to uncover the atomic details of macromolecules gone awry. For instance, the tumor suppressor p53 is one of the most popular proteins in cancer research, yet there is little structural information about its complete 3D organization. The Center for Structural Oncology (CSO) at Penn State University is working to address these impactful uncertainties. Using a wealth of cryo-EM resources in the CSO, we capture dynamic snapshots of p53 assemblies while preserving their disease-related context for drug discovery and therapeutic development. With these tools in hand, the CSO is working to engineer new molecular paradigms in creating a world without cancer.
Can Appeals for Peace Promote Tolerance and Mitigate Support for Extremism? Evidence from an Experiment with Adolescents in Burkina Faso
Authors: Grossman Allison N. , Nomikos William G. , Siddiqui Niloufer A. 
Published: March 2022

AbstractRecent efforts to improve attitudes toward outgroups and reduce support for extremists in violent settings report mixed results. Donors and aid organizations have spent millions of dollars to amplify the voices of moderate religious figures to counter violent extremism in West Africa, the Middle East, and South Asia. Despite this investment, we know little about whether such messaging persuades the primary recruits of violent extremist organizations: at-risk youth in fragile settings. In this paper, we consider whether pro-peace religious messaging can promote social cohesion among school-age respondents in Burkina Faso. Using a survey experiment, we find little evidence that such messages affect reported attitudes or behaviors toward religious extremism and find instead that it can have the unintended effect of increasing intolerance toward ethnic others. Our findings carry lessons about the inadvertent priming of ethnic identities that can result in a backlash effect among certain societal segments.
Atmospheric CO2 and Sea Surface Temperature Variability Cannot Explain Recent Decadal Variability of the Ocean CO2 Sink
Authors: DeVries Tim 
Published: March 2022

AbstractThe ocean is one of the most important sinks for anthropogenic CO2 emissions. Here, I use an ocean circulation inverse model (OCIM), ocean biogeochemical models, and pCO2 interpolation products to examine trends and variability in the oceanic CO2 sink. The OCIM quantifies the impacts of rising atmospheric CO2, changing sea surface temperatures, and gas transfer velocities on the oceanic CO2 sink. Together, these effects account for an oceanic CO2 uptake of 2.2 ± 0.1 PgC yr−1 from 1994 to 2007, and a net increase in the oceanic carbon inventory of 185 PgC from 1780 to 2020. However, these effects cannot account for the majority of the decadal variability shown in data‐based reconstructions of the ocean CO2 sink over the past 30 years. This implies that decadal variability of the ocean CO2 sink is predominantly driven by changes in ocean circulation or biology that act to redistribute both natural and anthropogenic carbon in the ocean.
