description: Past research has studied social determinants of attitudes toward foreign countries. Confounded by potential endogeneity biases due to unobserved factors or reverse causality, the causal impact of these factors on public opinion is usually difficult to establish. Using social media data, we leverage the suddenness of the COVID-19 pandemic to examine whether a major global event has causally changed American views of another country. We collate a database of more than 297 million posts on the social media platform Twitter about China or COVID-19 up to June 2020, and we treat tweeting about COVID-19 as a proxy for individual awareness of COVID-19. Using regression discontinuity and difference-in-difference estimation, we find that awareness of COVID-19 causes a sharp rise in anti-China attitudes. Our work has implications for understanding how self-interest affects policy preference and how Americans view migrant communities.

description: The recent breakthroughs of deep neural networks (DNNs) and the advent of billions of Internet of Things (IoT) devices have excited an explosive demand for intelligent IoT devices equipped with domain-specific DNN accelerators. However, the deployment of DNN accelerator enabled intelligent functionality into real-world IoT devices still remains particularly challenging. First, powerful DNNs often come at prohibitive complexities, whereas IoT devices often suffer from stringent resource constraints. Second, while DNNs are vulnerable to adversarial attacks especially on IoT devices exposed to complex real-world environments, many IoT applications require strict security. Existing DNN accelerators mostly tackle only one of the two aforementioned challenges (i.e., efficiency or adversarial robustness) while neglecting or even sacrificing the other. To this end, we propose a 2-in-1 Accelerator, an integrated algorithm-accelerator co-design framework aiming at winning both the adversarial robustness and efficiency of DNN accelerators. Specifically, we first propose a Random Precision Switch (RPS) algorithm that can effectively defend DNNs against adversarial attacks by enabling random DNN quantization as an in-situ model switch. Furthermore, we propose a new precision-scalable accelerator featuring (1) a new precision-scalable MAC unit architecture which spatially tiles the temporal MAC units to boost both the achievable efficiency and flexibility and (2) a systematically optimized dataflow that is searched by our generic accelerator optimizer. Extensive experiments and ablation studies validate that our 2-in-1 Accelerator can not only aggressively boost both the adversarial robustness and efficiency of DNN accelerators under various attacks, but also naturally support instantaneous robustness-efficiency trade-offs adapting to varied resources without the necessity of DNN retraining.

South African distribution: Port Alfred (EC) to the KZN border with Mozambique.
Remarks: The sawfish family Pristidae was problematic in the number of species and distribution until Faria et al. (2013) reviewed the family and concluded that two genera (Anoxypristis, Pristis) and five species (A. cuspidata, P. clavata, P. pectinata, P. pristis, and P. zijsron) were valid. The nomenclature of South Africa sawfishes is no different and is lengthy and convoluted with various names including P. microdon, P. pectinata, P. perrotteti, and P. pristis appearing in the literature. However, a review by Everett et al. (2015) found that two species, P. pristis and P. zijsron appear to be the only two that historically occurred in South African waters.

description: The increasing popularity of marital enrichment programs suggests a need for a systematic analysis of their effectiveness. Earlier evaluative studies contained numerous methodological shortcomings, making it difficult to draw inferences about enrichment-induced change. Twenty married couples participated in the Couples Communication Program (CCP) or a placebo control group. Measures of marital communication and perceived marital adjustment were obtained prior to the program, at the conclusion of the program and at a one month follow-up. The simulation measure of communication indicated that the experimental couples learned the skill taught in the CCP. However, there was no significant change in marital satisfaction. Empirical issues which should be addressed in future research were discussed.

description: We study the weight 2 graded piece of the compactly supported rational cohomology of the moduli spaces of curves $M_{g,n}$ and show that this can be computed as the cohomology of a graph complex that is closely related to graph complexes arising in the study of embedding spaces. For $n = 0$, we express this cohomology in terms of the weight zero compactly supported cohomology of $M_{g',n'}$ for $g' \leq g$ and $n' \leq 2$, and thereby produce several new infinite families of nonvanishing unstable cohomology groups on $M_g$, including the first such families in odd degrees. In particular, we show that the dimension of $H^{4g-k}(M_g)$ grows at least exponentially with $g$, for $k \in \{ 8, 9, 11, 12, 14, 15, 16, 18, 19 \}$.

Concretely, we present an Android app that deploys RTLola runtime monitors for the purpose of diagnosing automotive exhaust emissions. For this, it harvests the availability of cheap bluetooth adapters to the On-Board-Diagnostics (OBD) ports, which are ubiquitous in cars nowadays. We detail its use in the context of Real Driving Emissions (RDE) tests and report on sample runs that helped identify violations of the regulatory framework currently valid in the European Union.

description: Allelopathy is a biological phenomenon in which an organism produces biochemicals, known as allelochemicals that influence the growth, survival, and reproduction of other organisms. In plants, allelopathy often refers to the release of chemicals by one plant that inhibit or promote the growth of neighboring plants. These allelochemicals can be released through various plant parts, including leaves, roots, bark, and seeds, and may affect nutrient uptake, germination, and overall plant health. Allelopathy plays an important role in natural ecosystems, agriculture, and forestry. It can help plants compete for resources; deter herbivores, and control pests and diseases. Some common examples include black walnut (Juglans nigra), which releases juglone to inhibit the growth of nearby plants, and allelopathic weeds like garlic mustard (Alliaria petiolata), which release chemicals that hinder native plant species.

Remarks: Early reports of this species commented on it being a regular visitor to KZN during the summer months and it being one of the gamest fishes along the coast (Barnard, 1925). This appears to be the only confirmed Rhynchobatus species in South African waters and it appears to mostly be replaced by R. australiae in southern Mozambique. Although there are no confirmed records of R. australiae in South African waters it would not be unexpected as it is common in southern Mozambique.

description: We investigate the aerodynamic efficiency and flight dynamics of mono-wing and box-wing configurations across various parameters, including aspect ratio, velocity, and lift requirements. We find that although mono-wing configurations exhibit superior aerodynamic efficiency in certain regimes, box-wing designs perform better in circumstances like high velocities and increased lift demands. Box-wing configurations also prove advantageous when induced drag is higher than friction drag due to their ability to suppress the tip vortices. Furthermore, while analyzing the flight dynamics, low aspect ratio box-wing configurations show improved gust tolerance and stability in longitudinal and lateral dynamics. However, no substantial difference in flight dynamics is observed between box-wing and mono-wing designs for high aspect ratio configurations. The findings underscore the importance of selecting the appropriate wing configuration based on specific performance requirements and operational conditions.

Aim: The aim of this study was to measure the effect of training program regarding managing bullying behavior among staff nurses work engagement. Design: Quasi-experimental one group pre- posttest design was used in this study. Setting: The study was conducted at medical hospital which affiliated to El Fayuom University Hospitals. Sample: The subjects of the study included 132 out of 200 staff nurses working in El Fayuom University hospitals. Tools: Three tools were used for data collection, bullying behavior knowledge questionnaire, negative act questionnaire-revised, and Utrecht work engagement scale. Results: The results indicated that there was a highly statistical significant difference between pre /post, pre / follow up results regarding bullying behavior knowledge level, work engagement level , staff nurses negative acts level were decreased after implementation of bullying behavior management training program, Total work engagement scores among staff nurses had improved after applying bullying behavior management training program. Conclusion: There was a negative correlation between total bullying and total work engagement among staff nurses after applying bullying behavior management training program. Recommendations: Conducting regularly training programs to increase staff nurses' awareness about harmful effect of workplace bullying, and developing policies to prevent workplace bullying, and how to report bullying.

description: COVID-19 is not a universal killer. We study the spread of COVID-19 at the county level for the United States up until the 15th of August, 2020. We show that the prevalence of the disease and the death rate are correlated with the local socio-economic conditions often going beyond local population density distributions, especially in rural areas. We correlate the COVID-19 prevalence and death rate with data from the US Census Bureau and point out how the spreading patterns of the disease show asymmetries in urban and rural areas separately and are preferentially affecting the counties where a large fraction of the population is non-white. Our findings can be used for more targeted policy building and deployment of resources for future occurrence of a pandemic due to SARS-CoV-2. Our methodology, based on interpretable machine learning and game theory, can be extended to study the spread of other diseases.

South African distribution:?Endemic. Confirmed along the west coast from at least Langebaan (WC) to off the Transkei coast (EC) and possibly to central KZN, but records from outside this region should be carefully checked.
Remarks: The range for A. annulatus is poorly defined since it has frequently been misidentified with other South African guitarfish species, including A. blochii, A. leucospilus, A. ocellatus, and R. austini. In addition, records of this species outside South Africa also require confirmation. The species may eventually prove to be a South African endemic.

description: A general class of heat operators over non-archimedean local fields acting on $L_2$-function spaces on affinoid domains in the local field are developed. $L_2$-spaces and integral operators invariant under the action of a non-archimedean Schottky group are constructed in order to have nice function spaces and operators on Mumford curves. General wavelets are constructed which, together with functions coming from certain graph Laplacian eigenvectors, diagonalise these operators. The corresponding Cauchy problems for the heat equations with these operators are solved in the affirmative, and properties of wavelet eigenvalues and the spectral gaps of the operators on Mumford curves are studied.

description: We introduce a method to learn unsupervised semantic visual information based on the premise that complex events can be decomposed into simpler events and that these simple events are shared across several complex events. We first employ a clustering method to group representations producing a visual codebook. Then, we learn a dense representation by encoding the co-occurrence probability matrix for the codebook entries. This representation leverages the performance of the dense video captioning task in a scenario with only visual features. For example, we replace the audio signal in the BMT method and produce temporal proposals with comparable performance. Furthermore, we concatenate the visual representation with our descriptor in a vanilla transformer method to achieve state-of-the-art performance in the captioning subtask compared to the methods that explore only visual features, as well as a competitive performance with multi-modal methods. Our code is available at https://github.com/valterlej/dvcusi.

South Africa voucher material: See above for details on syntypes.
South African distribution: West coast from the Orange River (NC) to Langebaan Lagoon (WC). Its distribution eastwards may extend to Cape Point, but if so, it is rare south of Langebaan.
Remarks: Acroteriobatus blochii was once considered to be very rare and known from only a few specimens, but it was frequently misidentified as A. annulatus along the west coast of South Africa and Namibia. A coastal survey conducted along the west coast of South Africa and Namibia (D.A. Ebert & P.D. Cowley, unpubl. data) revealed this to be the most common guitarfish along the west coast, mostly replacing A. annulatus north of Langebaan Lagoon (WC) and extending into at least central Namibia (Compagno et al., 1989).

description: Chirality-induced spin selectivity (CISS) generates giant spin polarization in transport through chiral molecules, paving the way for novel spintronic devices and enantiomer separation. Unlike conventional transport, CISS magnetoresistance (MR) violates Onsager's reciprocal relation, exhibiting significant resistance changes when reversing electrode magnetization at zero bias. However, its underlying mechanism remains unresolved. In this work, we propose that CISS MR originates from charge trapping that modifies the electron tunneling barrier and circumvents Onsager's relation, distinct from previous spin polarization-based models. Charge trapping is governed by the non-Hermitian skin effect, where dissipation leads to exponential wavefunction localization at the ferromagnet-chiral molecule interface. Reversing magnetization or chirality alters the localization direction, changing the occupation of impurity/defect states in the molecule (i.e., charge trapping) -- a phenomenon we term magnetochiral charge pumping. Our theory explains why CISS MR can far exceed the ferromagnet spin polarization and why chiral molecules violate the reciprocal relation but chiral metals do not. Furthermore, it predicts exotic phenomena beyond the conventional CISS framework, including asymmetric MR induced by magnetic fields alone (without ferromagnetic electrodes), as confirmed by recent experiments. This work offers a deeper understanding of CISS and opens avenues for controlling electrostatic interactions in chemical and biological systems through the magnetochiral charge pumping.

Remarks: Accounts by Wallace (1967b, see fig. 15) and Compagno et al. (1989, see illustration on p. 79) described a Rhinobatos annulatus “Natal ” form that was distinguished by large brown spots from the “Cape” form. However, the “Natal” form is actually Rhinobatos austini, while the “Cape” form, which is now assigned to the genus Acroteriobatus, has numerous small eyespots on its dorsal surface. Furthermore, the recently described R. austini was also misidentified with R. holcorhynchus due to both species having a black teardrop-shaped blotch on the ventral surface of its snout. Recent re-examination of specimens from Mozambique and Madagascar has expanded the known range of R. austini. This species appears to inhabit a mostly coastal habitat from inshore to 107 m, but mostly less than 75 m depth, while R. holcorhynchus appears to occur in deeper water at depths from 75 m to at least 350 m (Séret et al., 2016a; Ebert & Gon, 2017). The illustration in the species account of R. holcorhynchus in Séret et al. (2016a, see fig. 10.20) is actually R. austini.

South African distribution: East coast from Port Shepstone to KZN border with Mozambique.
Remarks: The geographic range of R. holcorhynchus in East Africa, Madagascar, and the Mascarene Archipelago should be revisited given the misidentification with other regional Rhinobatos species, including R. austini and R. nudidorsalis. The scientific name Rhinobatos schlegelii appears in some earlier South African literature accounts since Smith (1949a, 1961 a, 1965) considered R. holcorhychus to be a junior synonym of it. However, most recent accounts do not recognize it as occurring in southern Africa, and consider its distribution to be restricted to the western North Pacific (Last et al., 2016b: 470; Séret et al., 2016a: 98, fig. 10.20).

description: Any subanalytic germ $(X,0) \subset (\mathbb R^n,0)$ is equipped with two natural metrics: its outer metric, induced by the standard Euclidean metric of the ambient space, and its inner metric, which is defined by measuring the shortest length of paths on the germ $(X,0)$. The germs for which these two metrics are equivalent up to a bilipschitz homeomorphism, which are called Lipschitz Normally Embedded, have attracted a lot of interest in the last decade. In this survey we discuss many general facts about Lipschitz Normally Embedded singularities, before moving our focus to some recent developments on criteria, examples, and properties of Lipschitz Normally Embedded complex surfaces. We conclude the manuscript with a list of open questions which we believe to be worth of interest.
