Advisors or Enablers? Bringing Professional Service Providers into the Guiding Principles’ Fold
Authors: RAMASASTRY Anita 
Published: June 2021

AbstractAfter a decade, different businesses adhere to the UN Guiding Principles on Business and Human Rights (UNGPs). Some key commercial entities, however, remain largely outside of the UNGPs universe, including professional service providers (PSPs) who are retained by businesses to provide expert advice and services. These advisors include lawyers, management consultants, architects and others. Some may have specialized units that provide advice on the UNGPs when retained solely for that purpose. But when asked to provide general commercial legal advice, to design a building, or restructure a business, such advisors do not typically appear to apply the UNGPs, to identify negative human rights impacts and tailor their advice in a way that prevents or mitigates such impacts. This article explores the connection between the advice provided by PSPs and negative human rights impacts. It underscores the critical need for these advisors to align their business processes and advisory services with the UNGPs to avoid being enablers of human rights abuses.
Conceptions of Epistemic Value
Authors: Perrine Timothy 
Published: June 2021

AbstractThis paper defends a conception of epistemic value that I call the “Simpliciter Conception.” On it, epistemic value is a kind of valuesimpliciterand being of epistemic value implies being of valuesimpliciter. I defend this conception by criticizing two others, what I call the Formal Conception and the Hybrid Conception. While those conceptions may be popular among epistemologists, I argue that they fail to explain why anyone should care that things are of epistemic value and naturally undercuts disputes about what is of epistemic value. I end by sketching and locating my conception within some increasingly popular views in meta-normativity.
Bounded Justice and the Limits of Health Equity
Authors: Creary Melissa S. 
Published: June 2021

AbstractPrograms, policies, and technologies — particularly those concerned with health equity — are often designed with justice envisioned as the end goal. These policies or interventions, however, frequently fail to recognize how the beneficiaries have historically embodied the cumulative effects of marginalization, which undermines the effectiveness of the intended justice. These well-meaning attempts at justice are bounded by greater socio-historical constraints. Bounded justice suggests that it is impossible to attend to fairness, entitlement, and equity when the basic social and physical infrastructures underlying them have been eroded by racism and other historically entrenched isms. Using the case of Brazil’s National Health Policy for the Black Population, this paper proposes that bounded justice can contribute to justice discourses by serving as a concept, a proffering to a multi-disciplinary conceptual framework, and a potential analytic for those interested in the design of policy, technology, and programmatic interventions towards health equity.
LOCAL MARINE RESERVOIR AGE (ΔR) RECONSTRUCTED BASED ON THE TSUNAMI DEPOSIT FROM PANGANI BAY (TANZANIA)
Authors: Soulet Guillaume , Maselli Vittorio 
Published: June 2021

ABSTRACTQuantifying the local marine reservoir age (ΔR) and its change over time is critical for precise radiocarbon calibration of marine samples and for the study of the ocean carbon cycle. ΔR values are scarce for the African coast facing the Indian Ocean, and the few values available were obtained from pre-bomb shells collected during the 19th century. Here, the ΔR value for calibrated year 1110 ± 25 (1σ) CE was reconstructed from radiocarbon dating and Bayesian analysis of marine and terrestrial materials coexisting in a tsunami deposit discovered in Pangani Bay (Tanzania, western Indian Ocean coast). The reconstructed ΔR of –8 ± 40 (1σ, n = 3) is similar to pre-bomb regional estimates and provides new information to investigate regional ΔR change over time. The Bayesian analysis of the dated samples revises the age of the tsunami event found in Pangani Bay to 1064–1157 cal CE (95.4% confidence level) or 1110 ± 25 (1σ) cal CE, about one century younger compared to the previous estimate. Our results indicate that the new ΔR value and the proposed calibration approach can be used to refine existing chronologies in the region, with implications for paleo-environmental reconstructions and archaeological studies of Early Swahili societies.
A HIGHLY PORTABLE AND INEXPENSIVE FIELD SAMPLING KIT FOR RADIOCARBON ANALYSIS OF CARBON DIOXIDE
Authors: Garnett Mark H , Newton Josephine-Anne , Parker Thomas C 
Published: June 2021

AbstractRadiocarbon (14C) analysis of carbon dioxide (CO2) can be extremely useful in carbon cycle studies because it provides unique information that can infer the age and source of this greenhouse gas. Cartridges containing the CO2-adsorbing zeolite molecular sieve are small and highly portable, which makes them more suitable for field campaigns in remote locations compared to some other CO2 collection methods. However, sampling with molecular sieve cartridges usually requires additional equipment, such as an infrared gas analyser, which can reduce portability and pose limitations due to power demands. In addition, 14C analysis of CO2 is increasingly being used in field experiments which require high numbers of replicate CO2 collections, placing extra pressure on an expensive and cumbersome collection apparatus. We therefore designed and built a molecular sieve CO2 sampling kit that utilizes a small, low power CO2 sensor. We demonstrate the reliability of the new kit for the collection of CO2 samples for 14C analysis in a series of laboratory and field tests. This inexpensive sampling kit is small, light-weight, highly portable, and has low power demands, making it particularly useful for field campaigns in remote and inaccessible locations.
Navigating gender in elite bargains: Women's movements and the quest for inclusive peace in Colombia
Authors: Phelan Alexandra , True Jacqui 
Published: June 2021

AbstractA growing body of scholarship connects the participation of women and the inclusion of gender provisions to the sustainability of peace settlements. But how do women's groups navigate gender power structures and gendered forms of violence within complex and fragile political bargaining processes aimed at ending large-scale conflict? The 2016 Colombian peace agreement, internationally applauded for its inclusion of strong gender provisions and women's participation as negotiators and peace advocates, is a significant case for examining these questions. Drawing on original case material, including interviews of key actors on different sides of the conflict – this article analyses the political bargaining dynamics within and among women's movements, the Santos government and the Revolutionary Armed Forces of Colombia (Fuerzas Armadas Revolucionarias de Colombia, FARC). We argue that the inclusion of women was pivotal in transforming the elite bargaining process and power structures of Colombian society enabling a gender-based approach to the substantive peace agenda addressing transitional gender justice for sexual violence survivors and gender-equal redistribution through land and rural reform programmes. The study suggests that deeply situated political bargaining analysis is essential to navigating gender in elite bargains rather than a one-size-fits-all approach to inclusive peace.
Point cloud modeling and slicing algorithm for trajectory planning of spray painting robot
Authors: Yu Xinyi , Cheng Zhaoying , Zhang Yikai , Ou Linlin 
Published: June 2021

AbstractTo improve the uniformity of coating thickness and spraying efficiency, new point cloud modeling and slicing algorithm are proposed to deal with free-form surfaces for the spray painting robot in this paper. In the process of point cloud modeling, the edge preservation algorithm is firstly presented to avoid damaging the edge characteristic of the point cloud model. For the spraying gun, the coating deposition model on the free-form surface is determined on the basis of the elliptic doubleβdistribution model. Then, the grid projection algorithm is proposed to obtain grid points between adjacent slices on the free-form surface. Based on this, the analytical solution for calculating the coating thickness at each grid point is obtained. The cross-section contour points are obtained by intercepting the point cloud model with several parallel slices, which is important for the trajectory planning of the spray painting robot. Finally, the uniformity of coating thickness is optimized in terms of the moving speed of the spraying gun and the slice thickness. The simulation and numerical experiment results show that the uniformity of coating thickness and spraying efficiency are improved using the proposed point cloud modeling and slicing algorithm.
Recalling Victory, Recounting Greatness: Second World War Remembrance in Xi Jinping's China
Authors: Chang Vincent K. L. 
Published: June 2021

AbstractThe recent surge in public remembrance of the Second World War in China has been substantially undergirded by a centrally planned and systematically implemented discursive shift which has remained overlooked in the literature. This study examines the revised official narrative by drawing on three cases from China's school curriculum, museums and formal diplomacy. It finds that the once dominant trope of “national victimization” no longer represents the main thrust in the Chinese Communist Party's (CCP) rhetoric on the Second World War. Under Xi Jinping, this has been replaced by a self-assertive and aspirational narrative of “national victory” and “national greatness,” designed to enhance Beijing's legitimacy and advance its domestic and foreign policy objectives. By emphasizing national unity and CCP–KMT cooperation, the new narrative offers an inclusive and unifying interpretation of China's war effort in which the victory in 1945 has come to rival the 1949 revolution as the critical turning point towards “national rejuvenation.” The increasingly Sino-centric and centrally controlled narrative holds implicit warnings to those challenging Beijing's claim to greatness.

AbstractThe spatial scales of whistler‐mode waves, determined by their generation process, propagation, and damping, are important for assessing the scaling and efficiency of wave‐particle interactions affecting the dynamics of the radiation belts. We use multi‐point wave measurements by two Van Allen Probes in 2013–2019 covering all MLTs at L = 2–6 to investigate the spatial extent of active regions of chorus and hiss waves, their wave amplitude distribution in the source/generation region, and the scales of chorus wave packets, employing a time‐domain correlation technique to the spacecraft approaches closer than 1,000 km, which happened every 70 days in 2012–2018 and every 35 days in 2018–2019. The correlation of chorus wave power dynamics using is found to remain significant up to inter‐spacecraft separations of 400–750 km transverse to the background magnetic field direction, consistent with previous estimates of the chorus wave packet extent. Our results further suggest that the chorus source region can be slightly asymmetrical, more elongated in either the azimuthal or radial direction, which could also explain the aforementioned two different scales. An analysis of average chorus and hiss wave amplitudes at separate locations similarly shows the reveals different radial and azimuthal extents of the corresponding wave active regions, complementing previous results based on THEMIS spacecraft statistics mainly at larger L > 6. Both the chorus source region scale and the chorus active region size appear smaller inside the outer radiation belt (at L < 6) than at higher L‐shells.
Overcoming the Model‐Data‐Fit Problem in Porous Media: A Quantitative Method to Compare Invasion‐Percolation Models to High‐Resolution Data

Published: June 2021

AbstractInvasion percolation (IP) models offer a computationally inexpensive way to simulate multiphase flow in porous media, but only very few studies have compared their results to actual laboratory experimental image data. One reason might be the difficulty in quantitative assessment: IP models do not have a notion of experimental time but only have an integer counter for simulation steps that imply a time order. Previous experiments‐to‐model comparison studies have either used perceptual similarity or spatial moments as measures of comparison. In this work, we present an objective and quantitative comparison method that overcomes the limitations of the traditional approaches. First, we perform a volume‐based time matching between real‐time experiments and IP model results. Then, we evaluate the quality of fit using a diffused version of the so‐called Jaccard coefficient, which is known from image recognition. We demonstrate our method's applicability on a laboratory‐scale experimental video of gas injection in homogeneous, saturated sand, comparing it to a Macro‐IP model's simulation results. We consider random realizations of the initial entry pressure field to capture the sand's inherent pore‐scale heterogeneity. We find that our proposed method is reliable and intuitive in identifying realistic model realizations. The “strictness”of the method can be adjusted to relevant scales of interest via the blurring (diffusion) radius of the compared images. Beyond the application presented here, our comparison method can be used to compare any high‐resolution space‐time model output to experimental data given as raster images, thus providing valuable insights for model development in many research areas.

Published: June 2021

AbstractThe brain’s efficient information processing is enabled by the interplay between its neuro-synaptic elements and complex network structure. This work reports on the neuromorphic dynamics of nanowire networks (NWNs), a unique brain-inspired system with synapse-like memristive junctions embedded within a recurrent neural network-like structure. Simulation and experiment elucidate how collective memristive switching gives rise to long-range transport pathways, drastically altering the network’s global state via a discontinuous phase transition. The spatio-temporal properties of switching dynamics are found to be consistent with avalanches displaying power-law size and life-time distributions, with exponents obeying the crackling noise relationship, thus satisfying criteria for criticality, as observed in cortical neuronal cultures. Furthermore, NWNs adaptively respond to time varying stimuli, exhibiting diverse dynamics tunable from order to chaos. Dynamical states at the edge-of-chaos are found to optimise information processing for increasingly complex learning tasks. Overall, these results reveal a rich repertoire of emergent, collective neural-like dynamics in NWNs, thus demonstrating the potential for a neuromorphic advantage in information processing.
Impaired reach-to-grasp kinematics in parkinsonian patients relates to dopamine-dependent, subthalamic beta bursts

AbstractExcessive beta-band oscillations in the subthalamic nucleus are key neural features of Parkinson’s disease. Yet the distinctive contributions of beta low and high bands, their dependency on striatal dopamine, and their correlates with movement kinematics are unclear. Here, we show that the movement phases of the reach-to-grasp motor task are coded by the subthalamic bursting activity in a maximally-informative beta high range. A strong, three-fold correlation linked beta high range bursts, imbalanced inter-hemispheric striatal dopaminergic tone, and impaired inter-joint movement coordination. These results provide new insight into the neural correlates of motor control in parkinsonian patients, paving the way for more informative use of beta-band features for adaptive deep brain stimulation devices.

AbstractDifferent strategies are used to meet optimal reproductive performance or manage reproductive health. Although exogenous human chorionic gonadotropin (hCG) and gonadotropin-releasing hormone (GnRH) agonists (A) are commonly used to trigger ovulation in estrous cycle synchronization, little is known about their effect on the ovarian follicle. Here, we explored whether hCG- and GnRH-A-induced native luteinizing hormone (LH) can affect the endocrine and molecular milieus of ovarian preovulatory follicles in pigs at different stages of sexual development. We collected ovaries 30 h after hCG/GnRH-A administration from altrenogest and pregnant mare serum gonadotropin (eCG)-primed prepubertal and sexually mature gilts. Several endocrine and molecular alternations were indicated, including broad hormonal trigger-induced changes in follicular fluid steroid hormones and prostaglandin levels. However, sexual maturity affected only estradiol levels. Trigger- and/or maturity-dependent changes in the abundance of hormone receptors (FSHR and LHCGR) and proteins associated with lipid metabolism and steroidogenesis (e.g., STAR, HSD3B1, and CYP11A1), prostaglandin synthesis (PTGS2 and PTGFS), extracellular matrix remodeling (MMP1 and TIMP1), protein folding (HSPs), molecular transport (TF), and cell function and survival (e.g., VIM) were observed. These data revealed different endocrine properties of exogenous and endogenous gonadotropins, with a potent progestational/androgenic role of hCG and estrogenic/pro-developmental function of LH.
Haptic awareness changes when lying down

Published: June 2021

AbstractAccurate localization of touch requires the integration of two reference frames—an internal (e.g., anatomical) and an external (e.g., spatial). Using a tactile temporal order judgement task with the hands crossed over the midline, we investigated the integration of these two reference frames. We manipulated the reliability of the visual and vestibular information, both of which contribute to the external reference frame. Visual information was manipulated between experiments (Experiment 1 was done with full vision and Experiment 2 was done while wearing a blindfold). Vestibular information was manipulated in both experiments by having the two groups of participants complete the task in both an upright posture and one where they were lying down on their side. Using a Bayesian hierarchical model, we estimated the perceptual weight applied to these reference frames. Lying participants on their side reduced the weight applied to the external reference frame and produced a smaller deficit; blindfolding resulted in similar reductions. These findings reinforce the importance of the visual system when weighting tactile reference frames, and highlight the importance of the vestibular system in this integration.
Assessment of image generation by quantum annealer
Authors: Sato Takehito , Ohzeki Masayuki , Tanaka Kazuyuki 
Published: June 2021

AbstractQuantum annealing was originally proposed as an approach for solving combinatorial optimization problems using quantum effects. D-Wave Systems has released a production model of quantum annealing hardware. However, the inherent noise and various environmental factors in the hardware hamper the determination of optimal solutions. In addition, the freezing effect in regions with weak quantum fluctuations generates outputs approximately following a Gibbs–Boltzmann distribution at an extremely low temperature. Thus, a quantum annealer may also serve as a fast sampler for the Ising spin-glass problem, and several studies have investigated Boltzmann machine learning using a quantum annealer. Previous developments have focused on comparing the performance in the standard distance of the resulting distributions between conventional methods in classical computers and sampling by a quantum annealer. In this study, we focused on the performance of a quantum annealer as a generative model from a different aspect. To evaluate its performance, we prepared a discriminator given by a neural network trained on an a priori dataset. The evaluation results show a higher performance of quantum annealer compared with the classical approach for Boltzmann machine learning in training of the generative model. However the generation of the data suffers from the remanent quantum fluctuation in the quantum annealer. The quality of the generated images from the quantum annealer gets worse than the ideal case of the quantum annealing and the classical Monte-Carlo sampling.

AbstractThis study analyzed the association of functionally significant SNPs of matrix metalloproteinase (MMP) genes in the development of peptic ulcer disease (PUD) in Caucasians from Central Russia. Ten SNPs of theMMP-1, MMP-2, MMP-3, MMP-8, andMMP-9genes were analyzed for association with PUD in a cohort of 798 patients with PUD (including 404H. pylori-positive and 394H. pylori-negative) and 347H. pylori-negative controls using logistic regression and assuming the additive, recessive, and dominant genetic models. The variants ofMMP-1,MMP-2,MMP-3, andMMP-8did not manifest any significant associations with the diseases. Five SNPs of theMMP-9gene demonstrated such association. Allele G of the rs17576MMP-9locus conferred a higher risk for PUD (ORadj = 1.31, pperm = 0.016), haplotype AACG of loci rs17576-rs3787268-rs2250889-rs17577 of theMMP-9gene decreased risk for PUD (ORadj = 0.17, pperm = 0.003). Also, allele C of rs3918249, allele G of rs17576 and haplotype CG of rs3918249-rs17576 of theMMP-9gene increased risk forH. pylori-positive PUD (ORadj = 1.82, pperm = 0.002; ORadj = 1.53–1.95 pperm = 0.001–0.013 and ORadj = 1.49 pperm = 0.009 respectively). The above loci and 50 linked to them possess significant regulatory effects and may affect the alternative splicing of four genes and the expression of 17 genes in various organs and tissues related to the PUD pathogenesis.
