Paediatric Obsessive–Compulsive Disorder and Comorbid Body Dysmorphic Disorder: Clinical Expression and Treatment Response
Authors: Racz Jason I. , Mathieu Sharna L. , McKenzie Matthew L. , Farrell Lara J. 
Published: January 2022

AbstractThis study explored the expression, occurrence, and treatment outcomes of comorbid body dysmorphic disorder (BDD) in 107 youth (7–17 years) seeking treatment for primary obsessive–compulsive disorder (OCD). In the overall sample, appearance anxiety (AA) was positively associated with OCD-related impairment, severity, symptom frequency, comorbid symptoms, and maladaptive emotion regulation. Comorbid BDD occurred in 9.35% of youth, equally affected males and females, and was associated with older age. AA negligibly reduced following treatment. Compared to those without (a) comorbid BDD and (b) without any comorbidity, youth with comorbid BDD reported greater social impairment and reduced global functioning but did not differ on the occurrence of comorbid anxiety and mood disorders. OCD response or remission rates did not differ. In youth with comorbid BDD, AA did not significantly reduce following treatment. Results suggest a more severe expression accompanies comorbid BDD in youth with OCD, with BDD persisting following OCD treatment.

Published: January 2022

AbstractIn this work, a regional-scale strategy to characterize the radon activity levels in the Canary Islands (Spain) is described. The main objectives of this strategy consisted of (1) studying the likely relationship between radon concentration and lithology of the rock matrix through the lithological data of 247 samples from volcanic rocks of the Canary Islands and (2) implementing a series of monitoring sites in the form of boreholes and wells to study the evolution of radon-in-air activity on a daily to yearly timescale.
Recrystallization in non-conventional microstructures of 316L stainless steel produced via laser powder-bed fusion: effect of particle coarsening kinetics

Abstract
Alloys processed by laser powder-bed fusion show distinct microstructures composed of dislocation cells, dispersed nanoparticles, and columnar grains. Upon post-build annealing, such alloys show sluggish recrystallization kinetics compared to the conventionally processed counterpart. To understand this behavior, AISI 316L stainless steel samples were constructed using the island scan strategy. Rhodonite-like (MnSiO3) nanoparticles and dislocation cells are found within weakly-textured grains in the as-built condition. Upon isothermal annealing at 1150 °C (up to 2880 min), the nucleation of recrystallization occurs along the center of the melt pool, where nuclei sites, high stored elastic energy, and local large misorientation are found in the as-built condition. The low value of the Avrami coefficient (n = 1.16) can be explained based on the non-random distribution of nucleation sites. The local interaction of the recrystallization front with nanoparticles speeds up their coarsening causing the decrease of the Zener-Smith pinning force. This allows the progression of recrystallization in LPBF alloys, although sluggish. These results allow us to understand the progress of recrystallization in LPBF 316L stainless steel, shedding light on the nucleation mechanisms and on the competition between driving and dragging pressures in non-conventional microstructures. They also help to understand the most relevant microstructural aspects applicable for tuning microstructures and designing new LPBF alloys.

Tailor the antibacterial efficiency of copper alloys by oxidation: when to and when not to
Authors: Luo Jiaqi , Ahmed Aisha , Pierson Jean-François , Mücklich Frank 
Published: January 2022

AbstractCopper and its relevant species, such as oxides and many alloys, have been recognised as potential antibacterial surfaces. Despite the relatively low antibacterial efficacy of cuprous oxide (Cu2O) compared to pure copper, it is still worth consideration in some scenarios. Taking copper-nickel co-sputtered thin films with two copper contents (55 and 92 at.%) as examples, this work investigated the potential of oxidation in altering the antibacterial behaviour of copper alloy surfaces. By heat treatment at 200–250 °C for 20–24 h, a layer mainly composed of Cu2O was successfully fabricated on the top of the Cu-Ni alloys. Antibacterial efficiency against Escherichia coli in 1 h was obtained by the droplet method and further compared. The coupons with 92 at.% copper became less effective after oxidation: the reduction rate declines from 97.0 to 74.3%; whereas the coupons with 55 at.% copper showed a large increase after oxidation, rising from 15.0 to 66.8%. The experiments described herein reveal a promising concept of oxidation in enhancing the less effective copper alloy surfaces for antibacterial applications.

Published: January 2022

AbstractImplementing complex algorithms for big data, artificial intelligence, and graph processing requires enormous effort. Succinct, declarative programs to solve complex problems that can be efficiently executed for batching and streaming data are in demand. This paper presents Nexus, a distributed Datalog evaluation system. It evaluates Datalog programs using thesemi-naivealgorithm for batch and streaming data using incremental and asynchronous iteration. Furthermore, we evaluate Datalog programs with aggregates to determine the advantages of implementing thesemi-naivealgorithm using incremental iteration on its performance. Our experimental results show that Nexus significantly outperforms acyclic dataflow-based systems.
Vibration-induced nanoscale friction modulation on piezoelectric materials
Authors: Cao Jiawei , Li Qunyang 
Published: January 2022

AbstractMechanical vibration, as an alternative of application of solid/liquid lubricants, has been an effective means to modulate friction at the macroscale. Recently, atomic force microscopy (AFM) experiments and model simulations also suggest a similar vibration-induced friction reduction effect for nanoscale contact interfaces, although an additional external vibration source is typically needed to excite the system. Here, by introducing a piezoelectric thin film along the contact interface, we demonstrate that friction measured by a conductive AFM probe can be significantly reduced (more than 70%) when an alternating current (AC) voltage is applied. Such real-time friction modulation is achieved owing to the localized nanoscale vibration originating from the intrinsic inverse piezoelectric effect, and is applicable for various material combinations. Assisted by analysis with the Prandtl—Tomlinson (P—T) friction model, our experimental results suggest that there exists an approximately linear correlation between the vibrational amplitude and the relative factor for perturbation of sliding energy corrugation. This work offers a viable strategy for realizing active friction modulation for small-scale interfaces without the need of additional vibration source or global excitation that may adversely impact device functionalities.

Published: January 2022

AbstractA very efficient one-pot procedure for the direct oxidation of aldehydes to esters mediated by visible-light is presented. Utilizing a combination of indium triflate and N-bromosuccinimide, NBS, with either ortho-esters or alcohols provided rapid access to a variety of esters. Certain substrates convert fully within a few seconds, other more challenging tert-butyl esters were formed in good yield after no more than 4 h.

Integrated market and nonmarket strategies: Empirical evidence from the S&P 500 firms’ climate strategies
Authors: Kim Younsung 
Published: January 2022

AbstractFirms with well-formulated competitive market strategies could still fail due to their lack of effective nonmarket strategy. Climate change poses significant threats to firms and presents firms’ need to develop nonmarket strategy integrated with market strategy. Relying on the unique dataset of US S&P 500 firms’ responses to climate change, this study seeks to ask why some firms attempt to engage in climate policy making, while others do not do so. The results found that firms with organizational resources and capabilities underlying their carbon market strategy are more likely to support mandatory climate policy. It sheds light on the significance of integrated market and nonmarket strategies, particularly when business opportunities are controlled more by governments than by markets.
On several notions of complexity of polynomial progressions
Authors: KUCA BORYS 
Published: January 2022

AbstractFor a polynomial progression
$$ \begin{align*}(x,\; x+P_1(y),\ldots,\; x+P_{t}(y)),\end{align*} $$
we define four notions of complexity: Host–Kra complexity, Weyl complexity, true complexity and algebraic complexity. The first two describe the smallest characteristic factor of the progression, the third refers to the smallest-degree Gowers norm controlling the progression, and the fourth concerns algebraic relations between terms of the progressions. We conjecture that these four notions are equivalent, which would give a purely algebraic criterion for determining the smallest Host–Kra factor or the smallest Gowers norm controlling a given progression. We prove this conjecture for all progressions whose terms only satisfy homogeneous algebraic relations and linear combinations thereof. This family of polynomial progressions includes, but is not limited to, arithmetic progressions, progressions with linearly independent polynomials
$P_1, \ldots ,\!P_t$
and progressions whose terms satisfy no quadratic relations. For progressions that satisfy only linear relations, such as
$$ \begin{align*}(x,\; x+y^2,\; x+2y^2,\; x+y^3,\; x+2y^3),\end{align*} $$
we derive several combinatorial and dynamical corollaries: first, an estimate for the count of such progressions in subsets of
$\mathbb {Z}/N\mathbb {Z}$
or totally ergodic dynamical systems; second, a lower bound for multiple recurrence; and third, a popular common difference result in
$\mathbb {Z}/N\mathbb {Z}$
. Lastly, we show that Weyl complexity and algebraic complexity always agree, which gives a straightforward algebraic description of Weyl complexity.
Increased potential for shell competition among hermit crabs (Pagurus beringanus and Pagurus granosimanus) in the rocky intertidal
Authors: Torjman Brooke Z. , Iyengar Erika V. 
Published: January 2022

AbstractWe examined the prevalence and shell use of two species of hermit crabs (Pagurus granosimanus and Pagurus beringanus) in exposed and protected microhabitats at five sites in the rocky temperate intertidal on San Juan Island, Washington, to compare present habitat partitioning and potential interspecific competition to that reported nearly 50 years ago. We found that, in contrast to previous findings, the two species of hermit crabs overlapped extensively at some sites, typically those with less wave action. While the hermit crabs typically inhabited certain types of shells significantly more than others, and that use was congruent across microhabitats and species of hermit crabs at the same site, the dominant domicile differed substantially across sites. We provide a more complete ranking of shell use than previous authors and note site-specific dominant shell use. We conclude that previous habitat partitioning by depth may have weakened at protected sites. We hypothesize that increasing temperatures have caused P. granosimanus to expand its range deeper into the intertidal, which may increase the degree of interspecific competition for shells at the edge of the species’ tidal height range, where they overlap. Whether the habitat shift by this hermit crab is due to recent alterations in climate (particularly elevated temperatures, ocean acidification and lower local open ocean salinity) is unknown, but warrants further study.
Overcoming the Other America: José Martí's Immanent Critique of the Unionist Paradigm
Authors: Simon Joshua 
Published: January 2022

AbstractThis article offers a new interpretation of the Cuban intellectual José Martí's international political thought. It argues that Martí's analysis of early US imperialism and call for Spanish American unity are best understood as an immanent critique of the “unionist paradigm,” a tradition of international political thought that originated in the American independence movements. Martí recognized the impediments that racism had placed in the way of both US and Spanish American efforts to stabilize the hemisphere's republics by uniting them under regional institutions. He argued that, in his own time, Anglo-Saxon supremacism had deprived US-led Pan-Americanism of all legitimacy, causing a crisis of international political order in the Americas. In the context of this crisis, he developed a revised, antiracist unionism that, he argued, would free Spanish America's republics from imperial aggression and interstate conflicts, making the region a global model of stable and inclusive self-rule.
Fregel: a functional domain-specific language for vertex-centric large-scale graph processing
Authors: IWASAKI HIDEYA , EMOTO KENTO , MORIHATA AKIMASA , MATSUZAKI KIMINORI , HU ZHENJIANG 
Published: January 2022

Abstract
The vertex-centric programming model is now widely used for processing large graphs. User-defined vertex programs are executed in parallel over every vertex of a graph, but the imperative and explicit message-passing style of existing systems makes defining a vertex program unintuitive and difficult. This article presents Fregel, a purely functional domain-specific language for processing large graphs and describes its model, design, and implementation. Fregel is a subset of Haskell, so Haskell tools can be used to test and debug Fregel programs. The vertex-centric computation is abstracted using compositional programming that uses second-order functions on graphs provided by Fregel. A Fregel program can be compiled into imperative programs for use in the Giraph and Pregel+ vertex-centric frameworks. Fregel’s functional nature without side effects enables various transformations and optimizations during the compilation process. Thus, the programmer is freed from the burden of program optimization, which is manually done for existing imperative systems. Experimental results for typical examples demonstrated that the compiled code can be executed with reasonable and promising performance.
The Ethics of Algorithms in Healthcare
Authors: Oxholm Christina , Christensen Anne-Marie S. , Nielsen Anette S. 
Published: January 2022

AbstractThe amount of data available to healthcare practitioners is growing, and the rapid increase in available patient data is becoming a problem for healthcare practitioners, as they are often unable to fully survey and process the data relevant for the treatment or care of a patient. Consequently, there are currently several efforts to develop systems that can aid healthcare practitioners with reading and processing patient data and, in this way, provide them with a better foundation for decision-making about the treatment and care of patients. There are also efforts to develop algorithms that provide suggestions for such decisions. However, the development of these systems and algorithms raises several concerns related to the privacy of patients, the patient–practitioner relationship, and the autonomy of healthcare practitioners. The aim of this article is to provide a foundation for understanding the ethical challenges related to the development of a specific form of data-processing systems, namely clinical algorithms.
Recommended Instruments for Analyzing Cyber Dating Violence: A Systematic Review
Authors: Martínez Soto Ainize , Ibabe Izaskun 
Published: January 2022

AbstractCyber dating violence is an emerging form of dating violence that may have serious health effects on adolescents and young people, and in recent years interest in its study has increased. In order to understand completely the nature and magnitude of the problem, a clear understanding of the concept, constructs and well-established measurement tools are needed. The goal of this study was to analyze the measurement instruments of cyber dating violence in adolescents and young adults, and to determine which are the best suitable to use. To accomplish these objectives a systematic review was carried out. After reviewing the literature, twenty-four measurement instruments were analyzed, with important differences found between them in terms, constructs, dimensions and measurement attributes, as well as differences in their assessed psychometric properties. Once the methodological quality evaluation of the instruments was carried out following COSMIN (COnsensus based Standards for the selection of health Measurement Instruments) guidelines, three scales were found to be recommendable depending on the age and cultural context of participants: Cyber Dating Abuse Questionnaire (Borrajo, Gámez-Guadix, Pereda, et al., 2015), Technology-facilitated Abuse in Relationships Scale (Brown & Hegarty, 2021), and Abuse in Teen Relationships (CARPA; Calvete et al., 2021).
Biologically effective dose of flumioxazin and pyroxasulfone for control of multiple herbicide–resistant waterhemp (Amaranthus tuberculatus) in soybean

Published: January 2022

AbstractTwo studies were conducted to ascertain the biologically effective dose (BED) of flumioxazin and pyroxasulfone for multiple herbicide–resistant (MHR) waterhemp [Amaranthus tuberculatus (Moq.) Sauer] control in soybean [Glycine max (L.) Merr.] in southwestern Ontario, Canada, during 2016 and 2017. In the flumioxazin study, the predicted flumioxazin doses for 50%, 80%, and 90% MHR A. tuberculatus control were 19, 37, and 59 g ai ha−1 at 2 wk after application (WAA) and 31, 83, and 151 g ai ha−1, respectively, at 12 WAA. The predicted flumioxazin doses to cause 5% and 10% soybean injury were 129 and 404 g ai ha−1, respectively, at 2 wk after emergence (WAE), and the predicted flumioxazin doses to obtain 50%, 80%, and 95% of the weed-free control plot’s yield were determined to be 3, 14, and 65 g ai ha−1, respectively. In the pyroxasulfone study, the predicted pyroxasulfone doses that provided 50%, 80%, and 90% MHR A. tuberculatus visible control were 25, 50, and 88 g ai ha−1 at 2 WAA and 41, 109, and 274 g ai ha−1 at 12 WAA, respectively. The dose of pyroxasulfone predicted for 80% reduction in MHR A. tuberculatus density was 117 g ai ha−1, and the doses of pyroxasulfone predicted for 80% and 90% reduction in A. tuberculatus biomass were 204 and 382 g ai ha−1, respectively. The predicted doses of pyroxasulfone that caused 5% and 10% injury in soybean at 2 WAE were 585 and 698 g ai ha−1, respectively. The predicted doses of pyroxasulfone required to obtain 50%, 80%, and 95% yield relative to the weed-free plots were 6, 24, and 112 g ai ha−1, respectively. Flumioxazin and pyroxasulfone applied preemergence at the appropriate doses provided early-season MHR A. tuberculatus control in soybean.
Extracting Hierarchical Dynamical Structure From a Multistable Geological System—The Himalayan Paleomonsoon
Authors: Gipp M. R. 
Published: January 2022

AbstractThe author presents an iterative approach to describing a data set, such as a paleoclimatic proxy or a model output, in terms of automata of successively higher order. The automata reflect dynamics acting on successively longer timescales and larger spatial scales. The method uses the computed probability density function from reconstructed state space portraits, over successive overlapping windows in time, of the record of magnetic susceptibility of loess and paleosols at Luochuan, central China. Areas of consistently high probability across several time windows represent areas of metastability, which are used as the predictive and successor states of a succession of Markov Chains that characterize the variability of the strength of the East Asian paleomonsoon at different time scales. Seven metastable states are thus identified, forming four Markov Chains, which show a marked increase in complexity of behavior of the paleomonsoon system throughout the Quaternary. A higher‐order automaton is suggested by the sequence of Markov Chains, suggesting differing cycles of dynamic behavior in the Early and Late Quaternary.
Increasing Heat‐Stress Inequality in a Warming Climate

Published: January 2022

AbstractAdaptation is key to minimizing heatwaves' societal burden; however, our understanding of adaptation capacity across the socioeconomic spectrum is incomplete. We demonstrate that observed heatwave trends in the past four decades were most pronounced in the lowest‐quartile income region of the world resulting in >40% higher exposure from 2010 to 2019 compared to the highest‐quartile income region. Lower‐income regions have reduced adaptative capacity to warming, which compounds the impacts of higher heatwave exposure. We also show that individual contiguous heatwaves engulfed up to 2.5‐fold larger areas in the recent decade (2010–2019) as compared to the 1980s. Widespread heatwaves can overwhelm the power grid and nullify the electricity dependent adaptation efforts, with significant implications even in regions with higher adaption capacity. Furthermore, we compare projected global heatwave exposure using per‐capita gross domestic product as an indicator of adaptation capacity. Hypothesized rapid adaptation in high‐income regions yields limited changes in heatwave exposure through the 21st century. By contrast, lagged adaptation in the lower‐income region translates to escalating heatwave exposure and increased heat‐stress inequality. The lowest‐quartile income region is expected to experience 1.8‐ to 5‐fold higher heatwave exposure than each higher income region from 2060 to 2069. This inequality escalates by the end of the century, with the lowest‐quartile income region experiencing almost as much heatwave exposure as the three higher income regions combined from 2090 to 2099. Our results highlight the need for global investments in adaptation capabilities of low‐income countries to avoid major climate‐driven human disasters in the 21st century.
