Connectivity of Ample, Conic, and Random Simplicial Complexes
Authors: Barmak Jonathan Ariel 
Published: January 2022

AbstractA simplicial complex is $r$-conic if every subcomplex of at most $r$ vertices is contained in the star of a vertex. A $4$-conic complex is simply connected. We prove that an $8$-conic complex is $2$-connected. In general a $(2n+1)$-conic complex need not be $n$-connected but a $5^n$-conic complex is $n$-connected. This extends results by Even-Zohar, Farber, and Mead on ample complexes and answers two questions raised in their paper. Our results together with theirs imply that the probability of a complex being $n$-connected tends to $1$ as the number of vertices tends to $\infty $. Our model here is the medial regime.
Capital Mobility and Taxation: State–Business Collusion in China
Authors: Chen Ling , Hollenbach Florian M 
Published: January 2022

AbstractDo more mobile firms pay lower taxes? Conventional wisdom argues that capital mobility creates downward pressure on corporate taxes, as firms can threaten to exit. Nevertheless, empirical findings are highly mixed and hard to reconcile, partly due to a lack of data at the microlevel. Using two comprehensive panel data sets with more than 780,000 Chinese firms over two decades, we find that firms with higher shares of mobile capital pay higher effective tax rates. We contend that this counterintuitive finding results from the strategic interaction between firms and governments. Knowing their vulnerability and sunk cost, firms with more fixed assets were more active in protecting themselves by bribing and colluding with local officials. Meanwhile, officials were more willing to seek bribes from these firms in exchange for tax cuts. In contrast, mobile firms were disadvantaged. Although capital mobility may provide additional bargaining power, firms with fixed assets can overcome this advantage through state–business collusion. Our quantitative and qualitative evidence show that fixed firms paid lower taxes in cities with cozy government–business relations. However, such advantages decreased after the launch of anti-corruption campaigns and in cities with higher fiscal transparency.
The “Connected” Caregivers: Exploring the Interplay of Left-Behind Women’s Socio-Structural Immobilities and Communicative Mobilities in Transnational Power Geometries
Authors: Chen Hong 
Published: January 2022

Abstract
Drawing on an ethnographic study on different groups of left-behind women (mothers, aunts, and grandmothers) in Fuqing, a major transnational migrant-labor-sending area in China, this article examines how they collaborate with their overseas family members in childrearing through digital media use. Applying the “im/mobilities” framework, this study explains how different left-behind caregivers use mediated communication as communicative mobilities to negotiate family roles and relationships in situated transnational power geometry. Despite the common structural constraints (rural patriarchy and inadequate social resources), left-behind women’s socio-structural immobilities vary depending on their specific relationship with migrants (conjugal, kinship, and intergenerational dynamics), which embodies the asymmetrical nature of transnationalism. The findings highlight the dynamic negotiation between left-behind caregivers’ communicative mobilities and their contextualized socio-structural immobilities, which leads to diverse forms of agency and disempowerment. This article shows that communicative mobility is not only manifested as media use but also embodied as media (non)use.
Lay Summary
Transnational labor migration has allowed people in poor areas to improve their financial well-being, but has also caused separations among many families. Thanks to the prevalence of various digital media (e.g., instant messaging, webcam and voice calls, and social media platforms, etc.), fragmented family members are able to maintain and manage different family relationships despite geographic constraints. This study draws on three groups of female caregivers (mothers, aunts, and grandmothers) in Fuqing, a major transnational migrant-labor-sending area in China. I am particularly interested in how these left-behind women collaborate with migrant parents to fulfil their duties of raising left-behind children through digital media. The findings suggest that left-behind women’s life experiences are not only related to gender norms and inadequate social resources (e.g., a lack of job opportunities and robust social welfare system) in rural China, but also pertinent to their specific relationship with migrants (e.g., conjugal, kinship, and intergenerational dynamics). While female caregivers’ different situations influence their media practices during childrearing collaboration with migrant parents, such media engagement also contributes to the shaping of their transnational family relationships.
When Is HILO Low? Price Image Formation Based on Frequency versus Depth Pricing Strategies
Authors: Sheehan Daniel , Hamilton Ryan , Chellappa Ramnath K 
Published: January 2022

Abstract
One of the prominent pricing decisions a retailer can make is its choice of pricing strategy. Previous research investigating consumers’ responses to stores with frequent, shallow price advantages relative to competitors (a frequency strategy) versus stores with infrequent, deep price advantages (a depth strategy) was all conducted by allowing people to simultaneously view prices from multiple stores, a setting that emphasized across-store comparisons. The present research finds that when a store’s prices are evaluated separately, as opposed to simultaneously across stores, many of the prominent findings of previous research are reversed. The authors demonstrate that without simultaneous comparisons across stores, consumers shift from using across-store prices as reference points to using within-category reference prices. As a result of this shift, deep price advantages are easier to evaluate than frequent price advantages, and therefore more influential on consumers’ formation of price image. When stores are evaluated separately, the result is most often a depth advantage, where stores with a HILO pricing strategy are evaluated as having a lower price image than EDLP stores, even when the average prices are the same. These results cannot be explained by prior work related to frequency and depth pricing strategies that relied on across-store comparisons.
The Off by 100% Bias: The Effects of Percentage Changes Greater than 100% on Magnitude Judgments and Consumer Choice
Authors: Fisher Matthew , Mormann Milica 
Published: January 2022

Abstract
Percentage changes greater than 100% are frequently used in consumer contexts; for example, a cordless vacuum cleaner may boast “125% longer runtime” compared to competitors. Via six studies (n = 2,395) and 11 supplementary studies (n = 3,249), the current research shows that consumers systematically underestimate the magnitude of percentage changes greater than 100%. Specifically, many consumers apply the relative size usage (e.g., “125% of,” equivalent to 25% more) instead of the appropriate relative change (e.g., “125% more,” equivalent to 100% more + 25% more), which leads them to be off by exactly 100% in their magnitude estimates. The rate of bias decreases when the difference between these two usages is emphasized. The Off by 100% bias occurs across a variety of consumer contexts, influencing behavioral intentions and incentive-compatible choice. The findings make theoretical contributions to research on processing of percentages, probability versus frequency formats, and magnitude judgments. Finally, understanding how different presentation formats of the same information can lead to different magnitude judgments enables marketers and policymakers to ensure more effective communication.
Spatio-temporal Variation of Spinosad Susceptibility in Drosophila suzukii (Diptera: Drosophilidae), a Three-year Study in California’s Monterey Bay Region

Published: January 2022

Abstract
Spinosyn insecticides are widely used in conventional berry production, and spinosad is regarded as the most effective insecticide for managing Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), spotted-wing drosophila, in organic berry crops. Following the 2017 identification of spinosad resistance in caneberry fields in the Watsonville area, Santa Cruz Co., California, we conducted a study to examine the seasonal and annual susceptibility of D. suzukii over a three-year period. Adult flies were collected from two conventional and two organic caneberry fields in the Monterey Bay region, California, at ‘early’, ‘middle’, and ‘late’ time points during the 2018–2020 growing seasons, and their susceptibility to spinosad was assessed. Results demonstrated that spinosad susceptibility in the D. suzukii field populations generally decreased during the fruit production season (from June through November), and over consecutive seasons. LC50 values of adults from the conventional sites were determined to be as high as 228.7 mg l−1 in 2018, 665.6 mg l−1 in 2019, and 2700.8 mg l−1 in 2020. For the organically managed fields, LC50s of adults were as great as 300.0 mg l−1 in 2018, 1291.5 mg l−1 in 2019, and 2547.1 mg l−1 in 2020. Resistance ratios based on the LC50 values were as high as 10.7-, 13.2-, and 16.9-fold in 2018, 2019, and 2020, respectively. These results should serve as a caution for growers in other production areas, facilitate informed choice of insecticides used in D. suzukii management, and emphasize the need to develop effective insecticide resistance management strategies for this insect.
Velocity gradients choice affecting seismic site response in deep alluvial basins: Application to the Venetian Plain (Northern Italy)
Authors: Cascone Valeria , Barone Ilaria , Boaga Jacopo 
Published: January 2022

Abstract
The average shear-wave velocity of the first 30 metres of subsoil and the depth of the engineering bedrock are considered the key parameters for simplified seismic site response modelling. However, a reliable estimate of the site amplification should consider the entire shear-wave velocity profile from the ground surface down to the engineering bedrock. In deep alluvial basins, a typical geological context where the soil–bedrock interface may lie below the penetration depth of most common prospecting methods, only the shallow velocity profile can be defined in detail, while the deeper structures are commonly extrapolated with linear equations. The choice of a realistic interpolation between the shallow and deep soil still remains an open issue. We compute the 1D seismic site response of two sectors of the Venetian Plain (Northern Italy) characterised by gravelly and sandy deep formations. We model the 1D soil columns using theoretical non-linear gradients proposed in literature for deep alluvial basins. The numerical modelling results, in terms of strong motion parameters, show variations in the seismic site response up to 20%. The effect of the velocity gradients is also evaluated comparing the numerical simulations with real accelerometers recorded by a deep borehole seismometer and a seismic station located at the top of the borehole. These results demonstrate that the selection of the velocity gradient is crucial for seismic site characterisation of deep alluvial basins. In particular, the study suggests which is the most conservative gradient among the ones tested in terms of ground motion hazard estimation.
Randomness study of the concatenation of generalized sequences
Authors: Cardell Sara D , Orúe Amalia B , Requena Verónica , Fúster-Sabater Amparo 
Published: January 2022

Abstract
Keystream sequences should look as random as possible, i.e. should present no logical pattern to be exploited in cryptographic attacks. The generalized self-shrinking generator, a sequence generator based on irregular decimation, produces a family of sequences with good cryptographic properties. In this work, we display a detailed analysis on the randomness of the sequences resulting from the concatenation of elements of this family. We apply the most important batteries of statistical and graphical tests providing powerful results and a new method to construct sequences with good cryptographic properties.
Global and saturated probabilistic approximations based on generalized maximal consistent blocks

Published: January 2022

AbstractIn this paper incomplete data sets, or data sets with missing attribute values, have three interpretations, lost values, attribute-concept values and ‘do not care’ conditions. Additionally, the process of data mining is based on two types of probabilistic approximations, global and saturated. We present results of experiments on mining incomplete data sets using six approaches, combining three interpretations of missing attribute values with two types of probabilistic approximations. We compare our six approaches, using the error rate computed as a result of ten-fold cross validation as a criterion of quality. We show that for some data sets the error rate is significantly smaller (5% level of significance) for lost values, for some data sets the smaller error rate is associated with attribute-concept values, and sometimes with ‘do not care’ conditions. Again, for some approaches the error rate is significantly smaller for saturated probabilistic approximations than for global probabilistic approximations, while for some approaches it is the other way around. Thus, for an incomplete data set, the best approach to data mining should be chosen by trying all six approaches.

Abstract
The Colorado potato beetle (Leptinotarsa decemlineata (Say)) is an insect that can adapt to various challenges, including temperature fluctuations or select insecticide treatments. This pest is also an ongoing threat to the potato industry. Small noncoding RNAs such as miRNAs, which can control posttranscriptionally the expression of various genes, and piRNAs, which can notably impact mRNA turnover, are modulated in insects under different conditions. Unfortunately, information regarding the expression status of key players involved in their synthesis and function is for the most part lacking. The current study thus aims at assessing the levels of such targets in L. decemlineata exposed to hot and cold temperatures as well as treated to the insecticides chlorantraniliprole, clothianidin, imidacloprid, and spinosad. Transcript expression levels of Ago1, Ago2, Ago3, Dcr2a, Dcr2b, Expo-5, Siwi-1, and Siwi-2, components of pathways associated with small noncoding RNA production or function, were measured by qRT-PCR and revealed modulation of select transcripts in response to temperature challenges and to select insecticides. RNAi-mediated reduction of Ago2 transcript levels in L. decemlineata injected with Ago2-targeting dsRNA and exposed to cold and warm temperatures was also conducted. Changes in survival rates were observed for the latter condition in dsRNA- versus saline-injected insects. These results showcase the differential expression of select targets involved in small noncoding RNA homeostasis and provide leads for the subsequent assessment of their involvement during stress response in L. decemlineata using RNAi-based approaches.
A randomized clinical trial of guided self-help intervention based on mindfulness for patients with hepatocellular carcinoma: effects and mechanisms
Authors: Liu Zengxia , Li Min , Jia Yong , Wang Shuo , Zheng Lufang , Wang Cong , Chen Li 
Published: January 2022

Abstract

Background
Compared with face-to-face mindfulness-based interventions (MBIs), online mindfulness interventions may be more convenient for patients with limited resources and can provide self-help mindfulness methods to improve the quality of life of cancer patients. This study investigated the effects of guided self-help mindfulness-based interventions (GSH-MBIs) on psychological distress, quality of life and sleep quality in patients with hepatocellular carcinoma and explored the underlying mechanisms.

Methods
A total of 122 patients with hepatocellular carcinoma were randomly divided into the intervention group or the conventional treatment group. Psychological distress, quality of life, sleep quality, psychological flexibility and perceived stress were evaluated in the groups before the intervention at baseline, after the intervention, at 1-month follow-up and 3-month follow-up. The intervention’s effects over time and the potential mediating effects were analysed using generalized estimating equations (GEE).

Results
GEE results indicated significant time–group interaction effects on psychological distress (P &lt; 0.001) and sleep quality (P &lt; 0.001). The intervention significantly improved psychological flexibility (β, −2.066; 95% CI, −3.631, −0.500) and reduced perceived stress (β, −2.639; 95% CI, −4.110, −1.169). Psychological flexibility and perceived stress played a mediating role in the observed results.

Conclusion
GSH-MBIs can improve psychological distress and sleep quality via changing the psychological flexibility and perceived stress in hepatocellular carcinoma patients.
Admissibility of Counterclaims: The Practice of UNCLOS Tribunals
Authors: de Herdt Sandrine 
Published: January 2022

Abstract
This article considers the admissibility and procedural aspects relating to the filing of counterclaims in international law, with particular reference to bodies exercising jurisdiction under the United Nations Convention on the Law of the Sea —namely the International Court of Justice, International Tribunal for the Law of the Sea and Arbitral Tribunal instituted under Annex VII to this Convention. Counterclaims in the context of UNCLOS tribunals raise specific questions. For instance, the ambiguity concerning the rules applicable to counterclaims presented in Annex VII proceedings has recently been dealt with by an Annex VII Arbitral Tribunal in The ‘Enrica Lexie’ Incident case. The approach of the Tribunal needs careful consideration. In the M/V “Virginia G” Case, the approach taken by ITLOS questions the manner of interpretation of the ‘direct connection’ requirement in the context of UNCLOS cases. For this purpose, the present study of counterclaims provides a comparative analysis of the rules and practices of the three aforementioned bodies.
The INDEPTH (Impact of Nuclear Domains on Gene Expression and Plant Traits) Academy: a community resource for plant science
Authors: Tatout Christophe , Mougeot Guillaume , Parry Geraint , Baroux Célia , Pradillo Mónica , Evans David 
Published: January 2022

Abstract
This Community Resource paper introduces the range of materials developed by the INDEPTH (Impact of Nuclear Domains on Gene Expression and Plant Traits) COST Action made available through the INDEPTH Academy. Recent rapid growth in understanding of the significance of epigenetic controls in plant and crop science has led to a need for shared, high-quality resources, standardization of protocols, and repositories for open access data. The INDEPTH Academy provides a range of masterclass tutorials, standardized protocols, and teaching webinars, together with a rapidly developing repository to support imaging and spatial analysis of the nucleus and deep learning for automated analysis. These resources were developed partly as a response to the COVID-19 pandemic, but also driven by needs and opportunities identified by the INDEPTH community of ~200 researchers in 80 laboratories from 32 countries. This community report outlines the resources produced and how they will be extended beyond the INDEPTH project, but also aims to encourage the wider community to engage with epigenetics and nuclear structure by accessing these resources.
A stress-associated protein OsSAP8 modulates gibberellic acid biosynthesis by reducing the promotive effect of transcription factor OsbZIP58 on OsKO2

Published: January 2022

Abstract
Gibberellic acid (GA) is a vital phytohormone for plant growth and development. GA biosynthesis is a complex pathway regulated by various transcription factors. Here we report a stress-associated protein 8 (OsSAP8), negatively involved in GA biosynthesis. Overexpression of OsSAP8 in rice resulted in a semi-dwarfism phenotype and reduced endogenous GA3 content. In contrast, an OsSAP8 knockout mutant exhibited higher endogenous GA3 content and slightly increased plant height. Sub-cellular localization analysis of OsSAP8 showed that it could enter the nucleus. Based on electrophoretic mobility shift assay and yeast one hybrid experiments, OsSAP8 was found to bind to the cis-acting regulatory element GADOWNAT of ent-kaurene oxidases (KO2, KO3, KO5). The results from dual-luciferase reporter assays showed that OsSAP8 does not activate LUC reporter gene expression. However, it could interact with basic leucine zipper 58 (OsbZIP58), which has strong transcriptional activation potential on OsKO2. Moreover, the interaction between OsSAP8, rice lesion simulating disease 1-like 1 (OsLOL1), and OsbZIP58 could reduce the promotive effect of transcription factor OsbZIP58 on OsKO2. These results provide some new insights on the regulation of GA biosynthesis in rice.
Iterative reconstruction excursions for Baryon Acoustic Oscillations and beyond

Published: January 2022

ABSTRACT
The density field reconstruction technique has been widely used for recovering the baryon acoustic oscillation (BAO) feature in galaxy surveys that has been degraded due to non-linearities. Recent studies advocated adopting iterative steps to improve the recovery much beyond that of the standard technique. In this paper, we investigate the performance of a few selected iterative reconstruction techniques focusing on the BAO and the broad-band shape of the two-point clustering. We include redshift-space distortions, halo bias, and shot noise and inspect the components of the reconstructed field in Fourier space and in configuration space using both density field-based reconstruction and displacement field-based reconstruction. We find that the displacement field reconstruction becomes quickly challenging in the presence of non-negligible shot noise and therefore present surrogate methods that can be practically applied to a much more sparse field such as galaxies. For a galaxy field, implementing a debiasing step to remove the Lagrangian bias appears crucial for the displacement field reconstruction. We show that the iterative reconstruction does not substantially improve the BAO feature beyond an aggressively optimized standard reconstruction with a small smoothing kernel. However, we find taking iterative steps allows us to use a small smoothing kernel more ‘stably’, i.e. without causing a substantial deviation from the linear power spectrum on large scales. In one specific example we studied, we find that a deviation of 13 per cent in $P(k\sim 0.1\, h{\rm \,\,Mpc^{-1}})$ with an aggressive standard reconstruction can reduce to 3–4 per cent with iterative steps.
