Game Penjelajah Ruang (The Space Exploration Game, Ganjaran) is a learning media in the form of an Android-based educational game to practice the mathematical reasoning skills of class VIII students on SPLDV questions. The purpose of this study was to describe students' mathematical reasoning abilities in solving SPLDV questions on Android-based of Ganjaran. The students' mathematical reasoning ability can be seen from the results of working on the SPLDV questions by students which are made based on mathematical reasoning indicators. The type of research used is descriptive qualitative research. The subjects of this study were students of class VIII SMP Negeri 2 Krian as many as 4 students who had played the Ganjaran. The test instrument used in this study was a 5-point SPLDV reasoning question with short answers. From the results of the study, the average value of students' mathematical reasoning abilities was 56.25 which was quite sufficient. Overall, the indicator of mathematical reasoning ability that is mostly mastered by students is indicator c (drawing conclusions, compiling evidence, providing reasons or evidence for the correctness of the solution), while the indicator of student mathematical reasoning that is less mastered by students is indicator a (proposing conjectures).
Prenatal Depressive Symptoms, Self-Rated Health, and Diabetes Self-Efficacy: A Moderated Mediation Analysis

Background: Diabetes leads to risk for pregnant persons and their fetuses and requires behavioral changes that can be compromised by poor mental health. Poor self-rated health (SRH), a reliable predictor of morbidity and mortality, has been associated with depressive symptoms and lower self-efficacy in patients with diabetes. However, it is unclear whether SRH mediates the association between depressive symptoms and self-efficacy in pregnant patients with diabetes and whether the healthcare site moderates the mediation. Thus, we sought to test these associations in a racially and ethnically diverse sample of pregnant individuals diagnosed with diabetes from two clinical settings. Materials and methods: This was an observational, cross-sectional study of 137 pregnant individuals diagnosed with diabetes at two clinical study sites. Participants self-administered a demographic questionnaire and measures designed to assess depressive symptoms, SRH in pregnancy, and diabetes self-efficacy. A moderated mediation model tested whether these indirect effects were moderated by the site. Results: The results show that SRH mediated the association between depressive symptoms and diabetes self-efficacy. The results also showed the site moderated the mediating effect of SRH on depressive symptoms and diabetes self-efficacy. Conclusions: Understanding the role of clinical care settings can help inform when and how SRH mediates that association between prenatal depressive symptoms and self-efficacy in diabetic patients.
Polysiloxane-Based Polyurethanes with High Strength and Recyclability

Polysiloxanes have attracted considerable attention in biomedical engineering, owing to their inherent properties, including good flexibility and biocompatibility. However, their low mechanical strength limits their application scope. In this study, we synthesized a polysiloxane-based polyurethane by chemical copolymerization. A series of thermoplastic polysiloxane-polyurethanes (Si-TPUs) was synthesized using hydroxyl-terminated polydimethylsiloxane containing two carbamate groups at the tail of the polymer chains 4,4′-dicyclohexylmethane diisocyanate (HMDI) and 1,4-butanediol as raw materials. The effects of the hard-segment content and soft-segment number average molecular weight on the properties of the resulting TPUs were investigated. The prepared HMDI-based Si-TPUs exhibited good microphase separation, excellent mechanical properties, and acceptable repeatable processability. The tensile strength of SiTPU-2K-39 reached 21.5 MPa, which is significantly higher than that of other flexible polysiloxane materials. Moreover, the tensile strength and breaking elongation of SiTPU-2K-39 were maintained at 80.9% and 94.6%, respectively, after three cycles of regeneration. The Si-TPUs prepared in this work may potentially be used in gas separation, medical materials, antifouling coatings, and other applications.
The impact of the Covid-19 pandemic on the uptake of routine maternal and infant vaccines globally: A systematic review

Maintaining routine vaccination coverage is essential to avoid outbreaks of vaccine-preventable diseases. We aimed to understand the international impact of the COVID-19 pandemic on routine vaccination in pregnant women and children aged 0-5-years-old. A systematic review of quantitative and mixed methods studies exploring changes in vaccination coverage, vaccination services, and vaccine confidence since the start of the Covid-19 pandemic was conducted. MEDLINE, EMBASE, CINHAL, PsychINFO, Web of Science, Google Scholar, World Health Organisation, UK Government Joint Committee on Vaccination and Immunisation (including EU and US equivalents), and SAGE Journals were searched between 15-17th June 2021. Selected studies included pregnant women, health professionals, and/or infants aged 0-5-years-old including their parents (population); reported on the Covid-19 pandemic (exposure); presented comparisons with pre-COVID-19 pandemic period (comparator) and reported changes in routine maternal and infant vaccination coverage, services, and confidence (outcomes). Sources published only in non-English language were excluded. The Newcastle Ottawa Scale was used to assess study quality and risk of bias (ROB), and a narrative synthesis was undertaken. This review has been registered with PROSPERO (CRD42021262449). 30 studies were included in the review; data from 20 high-income countries (HICs), seven low- and middle-income countries (LMICs), and three regional studies (groups of countries). 18 studies had a low ROB, 12 had a higher risk, however both low and high ROB studies showed similar results. Two studies meeting the inclusion criteria discussed changes in routine vaccinations for pregnant women while 29 studies discussed infants. Both groups experienced declines in vaccination coverage (up to -79%) with larger disruptions in the accessibility and delivery of vaccination services reported within LMICs compared to HICs. Changes in vaccine confidence remained unclear. The COVID-19 pandemic resulted in decreased vaccine coverage and reduced routine vaccination services for pregnant women and infants, impacts on vaccine confidence requires more research.
Measurement-induced nonclassical states from a coherent state heralded by Knill–Laflamme–Milburn-type interference

We theoretically generate nonclassical states from a coherent state heralded by Knill–Laflamme–Milburn (KLM)-type interference. Injecting a coherent state in signal mode and two single-photon sources in the other two auxiliary modes of KLM-type interferometry, a broad class of useful nonclassical states is obtained in the output signal port after making two single-photon-counting measurements in the two output auxiliary modes. The nonclassical properties, in terms of the antibunching effect and the squeezing effect as well as the negativity of the Wigner function, are studied in detail by adjusting the interaction parameters. The results show that the input coherent state can be transformed into non-Gaussian states with higher nonclassicality after measurement induction. The maximum squeezing of our generated states is about 1.97928 dB.
Rare is beautiful? Rareness, technology value, and the moderating role of search domain and knowledge maturity

What makes a technology valuable? Characterizing the value as the degree of impact on subsequent technology development and focusing on the rareness as a composite measure of novelty and conventionality representing the relative position of a technology in a technology space, we advance a theory on the relationship between the rareness and value of a technology as well as the moderating role of search basis in shaping the relationship. We build our theory exploiting the fundamental trade‐off between the benefits of adopting a rare technology in pursuing greater recombinant potential and the costs of understanding the rare technology to be adopted and finding complementary technologies for successfully integrating the rare technology in the subsequent technology development process. Using US firm patent data in nanotechnology, we find that the relationship between the rareness and value of a technology exhibits an inverted‐U shape, consistent with our theoretical expectation. Further, the search basis of the focal technology moderates this relationship such that the rareness–value relationship becomes steeper when the technology is built on more local knowledge but flatter if the technology embeds more mature knowledge. Our study contributes to the extant literature seeking to illuminate the process by which valuable technologies arise.
Gender differences in grades versus grade penalties: Are grade anomalies more detrimental for female physics majors?

Creating equitable learning environments has been an area of significant focus for physics education researchers in recent years. Here we introduce a framework that posits that grade penalty is a measure of academic self-concept and investigate if there are gender differences in grade penalties in physics courses for students majoring in physics. In order to quantify grade penalty, we define grade anomaly as the difference between a student ’ s grade in a course under consideration and their grade point average (GPA) in all other classes thus far. A grade anomaly lower than students expected grade based on their GPA is a grade penalty and higher than expected average grade is a grade bonus. Our framework posits that since women have traditionally been marginalized in physics, female physics majors are more likely to be negatively impacted by a grade penalty in their courses since their academic self-concept as a physics major hinges on them securing a certain grade. In the study presented here, we examine the average grade anomalies across a number of courses for female and male physics majors. We find that these students received grade penalties in almost all physics courses studied, though there were grade bonuses in a few laboratory courses. We also find that in physics courses, on average, women often had larger grade penalties than men, especially in introductory courses. We hypothesize that, because their grade penalties are often larger than men ’ s, women ’ s decisions to pursue a physics major and career may be particularly affected by grade penalties received in their various courses. Furthermore, the grade penalty measure can be easily computed by the physics programs concerned with equity.
Proteo-Molecular Investigation of Cultivated Rice, Wild Rice, and Barley Provides Clues of Defense Responses against Rhizoctonia solani Infection

Rhizoctonia solani is a soil-borne fungus causing sheath blight disease in cereal crops including rice. Genetic resistance to sheath blight disease in cereal crops is not well understood in most of the host(s). Aside from this, a comparative study on the different hosts at the biochemical and proteomic level upon R. solani infection was not reported earlier. Here, we performed proteomic based analysis and studied defense pathways among cultivated rice (cv. Pusa Basmati-1), wild rice accession (Oryza grandiglumis), and barley (cv. NDB-1445) after inoculation with R. solani. Increased levels of phenol, peroxidase, and β-1, 3-glucanase were observed in infected tissue as compared to the control in all of the hosts. Wild rice accession O. grandiglumis showed a higher level of biochemical signals than barley cv. NDB 1445 and cultivated rice cv. Pusa Basmati-1. Using two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and mass spectrometry (MS), differently expressed proteins were also studied in control and after inoculation with R. solani. Wild rice accession O. grandiglumis induced a cysteine protease inhibitor and zinc finger proteins, which have defense functions and resistance against fungal pathogens. On the other hand, barley cv. NDB-1445 and cultivated rice cv. Pusa Basmati-1 mainly induce energy metabolism-related proteins/signals after inoculation with R. solani in comparison to wild rice accession O. grandiglumis. The present comprehensive study of R. solani interaction using three hosts, namely, Pusa Basmati-1 (cultivated rice), O. grandiglumis (wild rice), and NDB-1445 (barley) would interpret wider possibilities in the dissection of the protein(s) induced during the infection process. These proteins may further be correlated to the gene(s) and other related molecular tools that will help for the marker-assisted breeding and/or gene editing for this distressing disease among the major cereal crops.
Effects of Cisnormative Beauty Standards on Transgender Women’s Perceptions and Expressions of Beauty

The authors conducted a qualitative study exploring the effects of cisnormative beauty standards on transgender women’s perceptions and expressions of beauty. Twelve self-identified Caucasian transgender women completed a semistructured interview that provided descriptive data related to the women’s perceptions of societal beauty standards. Analysis of the data revealed the following primary themes: Participants viewed the beauty of transgender and cisgender women as diverse or as encompassing a broad range of variability; societal beauty standards were influential on participants’ expressions of beauty; and participants’ viewed out-group transphobia as a factor contributing to discriminatory and prejudicial perceptions of transwomen’s beauty.
Investigating p62 Concentrations in Cerebrospinal Fluid of Patients with Dementia: A Potential Autophagy Biomarker In Vivo?

Several studies have revealed defects in autophagy in neurodegenerative disorders including Alzheimer’s disease (AD) and frontotemporal dementia (FTD). SQSTM1/p62 plays a key role in the autophagic machinery and may serve as a marker for autophagic flux in vivo. We investigated the role of p62 in neurodegeneration, analyzing its concentrations in the CSF of AD and FTD patients. We recruited 76 participants: 22 patients with AD, 28 patients with FTD, and 26 controls. CSF p62 concentrations were significantly increased in AD and FTD patients when compared to controls, which persisted after adjusting for age (p = 0.01 and p = 0.008, respectively). In female FTD patients, p62 positively correlated with the neurodegenerative biomarkers t-Tau and p-Tau. A significant correlation between CSF p62 concentrations and several clinical features of AD was found. Our data show that p62 is increased in CSF of AD and FTD patients, suggesting a key role of autophagy in these two disorders. The levels of p62 in CSF may reflect an altered autophagic flux, and p62 could represent a potential biomarker of neurodegeneration.
Co-Evolutionary Location-Routing Model of Medical Isolation Areas for Major Public Health Emergencies Considering the Uncertainty of Future Traffic Environment

With the continuous development of the COVID-19 pandemic, the selection of locations for medical isolation areas has not always been optimal for the timely transportation of infected people, or those suspected of being infected. This has resulted in failure to control the rate of spread of infection cases in time. To address this problem, this paper proposes a co-evolutionary location-routing optimization (CELRO) model of medical isolation areas for use in major public health emergencies to develop a rapid location-routing scheme for epidemic isolation, including the selection of locations of medical isolation facilities per area and the optimal route per vehicle to each infected person. Specifically, this paper solves the following two sub-problems: (i) calculate the shortest transportation times and corresponding routes from any medical isolation area to any person infected or suspected of being infected, and (ii) calculate the location scheme for distribution of isolation areas. Different from previous studies, the vehicle operating characteristics and the interference of uncertainty of the traffic environment are considered in the proposed model. To find an appropriate scheme for location of medical isolation areas with the shortest travel times, a co-evolutionary clustering algorithm (CECA), which is a combination of some separated evolutionary programming operations, is proposed to solve the model. Various network sizes and uncertainty combinations are used to design some comparative tests, which aim to verify the effectiveness of the proposed model. In the experiment section, CELRO reduced travel time by at least 14% compared with other methods. This finding can provide an effective theoretical basis for optimizing the spatial layout of medical isolation areas or the location planning of new medical facilities.
Stability of aluminium reduction cells with mean flow

We report results of the linear stability analysis undertaken to investigate the effect of the mean flow of liquid metal on the stability of aluminum reduction cells. A simplified model of the cell is considered that consists of thin layers of aluminum and cryolite superimposed in an infinite horizontal channel with electrically non-conducting walls. A vertical uniform magnetic field and an electric current are applied in the opposite directions. In the basic steady state, a uniform flow of aluminum is assumed, while cryolite is at rest. The onset of the instability is caused by the action of two different mechanisms. The first is the Kelvin-Helmholtz instability of the mean flow. The second, essentially the MHD mechanism, is a consequence of destabilizing electromagnetic (Lorentz) forces produced by nonuniformities of the electric current due to interface deflections. We use the shallow water approximation and solve the problem for the cases of pure Kelvin-Helmholtz (zero magnetic field) and pure MHD (zero mean flow) instabilities and for the general case. We compute the stability chart and derive the parameters that determine the stability threshold. It is found that, while both playing a destabilizing role, the instability mechanisms do not affect each other. In particular, a uniform mean flow changes the direction of propagation of interfacial waves but leaves the MHD stability threshold unaltered. Figs 4, Refs 12.
Heterotic on Half-flat

We study the eﬀective action of the heterotic string compactiﬁed on particular half-ﬂat manifolds which arise in the context of mirror symmetry with NS-NS ﬂux. We explicitly derive the superpotential and K¨ahler potential at lowest order in α ′ by a reduction of the bosonic action. The superpotential contains new terms depending on the K¨ahler moduli which originate from the intrinsic geometrical ﬂux of the half-ﬂat manifolds. A generalized Gukov formula, valid for all manifolds with SU(3) structure, is derived from the gravitino mass term. For the half-ﬂat manifolds it leads to a superpotential in agreement with our explicit bosonic calculation. We also discuss the inclusion of gauge ﬁelds.
ULTRAHIGH-ENERGY COSMIC RAYS AND BLACK HOLE MERGERS

The recent detection of the gravitational-wave source GW150914 by the LIGO collaboration motivates a speculative source for the origin of ultrahigh-energy cosmic rays as a possible byproduct of the immense energies achieved in black hole (BH) mergers, provided that the BHs have spin, as seems inevitable, and there are relic magnetic fields and disk debris remaining from the formation of the BHs or from their accretion history. We argue that given the modest efficiency < 0.01 required per event per unit of gravitational-wave energy release, merging BHs potentially provide an environment for accelerating cosmic rays to ultrahigh energies. The presence of tidally disrupted planetary or asteroidal debris could lead to associated fast radio bursts.
T RACE A LOT BUT KEEP A LITTLE : SAMPLING TECHNIQUES FOR DISTRIBUTED TRACING FRAMEWORKS

Distributed tracing is a core component of cloud and data-center systems, and provides visibility into their end-to-end runtime behavior. To reduce computational and storage over-heads, most tracing frameworks do not keep all traces, but sample them uniformly at random . While effective at reducing overheads, uniform random sampling inevitably captures redundant, common-case execution traces, which are less useful for analysis and troubleshooting tasks. In this work, we investigate biased trace sampling, whose goal is to capture qualitatively more diverse traces, by weighting sampling decisions towards edge-case code paths, infrequent request types, and anomalous events. We present two different sampling approaches, one of which is based on the trace comparison while the other relies on modeling the system’s
The Influence of Creator Information on Preference for Artificial Intelligence- and Human-generated Artworks

Purpose: Researchers have shown that aesthetic judgments of artworks depend on contexts, such as the authenticity of an artwork (Newman & Bloom, 2011) and an artwork’s location of display (Kirk et al., 2009; Silveira et al., 2015). The present study aims to examine whether contextual information related to the creator, such as whether an artwork was created by a human or artificial intelligence (AI), influences viewers’ preference judgments of an artwork. Methods: Images of Impressionist landscape paintings were selected as human-made artworks. AI-made artwork stimuli were created using Google’s Deep Dream Generator by mimicking the Impressionist style via deep learning algorithms. Participants performed a preference rating task on each of the 108 artwork stimuli accompanied by one of the two creator labels. After this task, an art experience questionnaire (AEQ) was given to participants to examine whether individual differences in art experience influence their preference judgments. Results: Setting AEQ scores as a covariate in a two-way ANCOVA analysis, the stimuli with the human-made context were preferred over the stimuli with the AI-made context. Regarding the types of stimuli, the viewers preferred AI-made stimuli to human-made stimuli. There was no interaction effect between the two factors. Conclusion: These results suggest that preferences for visual artworks are influenced by the contextual information of the creator when the individual differences in art experience are controlled.
Parenting Styles Predict Future-Oriented Cognition in Children: A Cross-Sectional Study

Parenting is a crucial environmental factor in children’s social and cognitive development. This study investigated the association between parenting styles and future-oriented cognition skills in elementary school-aged children. Cross-sectional data were collected from parents of 200 Iranian elementary school aged children (6–13 years), 139 boys and 61 girls. Baumrind’s Parenting Styles Questionnaire and Children’s Future Thinking Questionnaire (CFTQ) were administered to parents. There was a significant positive association between authoritative parenting and children’s abilities in prospective memory, episodic foresight, planning, delay of gratification, and future-oriented cognition total score. In contrast, authoritarian parenting was negatively correlated with children’s abilities in planning, delay of gratification, and future-oriented cognition. Increases in authoritative parenting scores predicted better future-oriented cognition abilities in children.
