Companies Committed to Responsible AI: From Principles towards Implementation and Regulation?
Authors: de Laat Paul B. 
Published: October 2021

AbstractThe term ‘responsible AI’ has been coined to denote AI that is fair and non-biased, transparent and explainable, secure and safe, privacy-proof, accountable, and to the benefit of mankind. Since 2016, a great many organizations have pledged allegiance to such principles. Amongst them are 24 AI companies that did so by posting a commitment of the kind on their website and/or by joining the ‘Partnership on AI’. By means of a comprehensive web search, two questions are addressed by this study: (1) Did the signatory companies actually try to implement these principles in practice, and if so, how? (2) What are their views on the role of other societal actors in steering AI towards the stated principles (the issue of regulation)? It is concluded that some three of the largest amongst them have carried out valuable steps towards implementation, in particular by developing and open sourcing new software tools. To them, charges of mere ‘ethics washing’ do not apply. Moreover, some 10 companies from both the USA and Europe have publicly endorsed the position that apart from self-regulation, AI is in urgent need of governmental regulation. They mostly advocate focussing regulation on high-risk applications of AI, a policy which to them represents the sensible middle course between laissez-faire on the one hand and outright bans on technologies on the other. The future shaping of standards, ethical codes, and laws as a result of these regulatory efforts remains, of course, to be determined.
Free boundary methods and non-scattering phenomena
Authors: Salo Mikko , Shahgholian Henrik 
Published: October 2021

AbstractWe study a question arising in inverse scattering theory: given a penetrable obstacle, does there exist an incident wave that does not scatter? We show that every penetrable obstacle with real-analytic boundary admits such an incident wave. At zero frequency, we use quadrature domains to show that there are also obstacles with inward cusps having this property. In the converse direction, under a nonvanishing condition for the incident wave, we show that there is a dichotomy for boundary points of any penetrable obstacle having this property: either the boundary is regular, or the complement of the obstacle has to be very thin near the point. These facts are proved by invoking results from the theory of free boundary problems.
Assessing Proof Reading Comprehension Using Summaries
Authors: Davies Ben , Jones Ian 
Published: October 2021

AbstractIn this paper, we explore the role of mathematical proof summaries as a tool for capturing students’ reading comprehension of a given proof. We present an interview study based on mathematicians’ pairwise evaluations of student-produced summaries of a proof demonstrating the uncountability of the open unit interval. We present a thematic analysis, exploring features of mathematicians’ pairwise decision-making and their priorities in evaluating summaries. We argue that the students’ proof summaries shared several properties with traditional modes of proof-writing and were frequently evaluated against similar conventions. We consider the consequences for research and practice with proof comprehension and conclude that proof summaries have the potential to form the basis of a new approach to assessment in this area.
Biochar alleviates metal toxicity and improves microbial community functions in a soil co-contaminated with cadmium and lead
Authors: Azadi Nahid , Raiesi Fayez 
Published: October 2021

AbstractSoil amendment with biochar alleviates the toxic effects of heavy metals on microbial functions in single-metal contaminated soils. Yet, it is unclear how biochar application would improve microbial activity and enzymatic activity in soils co-polluted with toxic metals. The present research aimed at determining the response of microbial and biochemical attributes to addition of sugarcane bagasse biochar (SCB) in cadmium (Cd)-lead (Pb) co-contaminated soils. SCBs (400 and 600 °C) decreased the available concentrations of Cd and Pb, increased organic carbon (OC) and dissolved organic carbon (DOC) contents in soil. The decrease of metal availability was greater with 600 °C SCB than with 400 °C SCB, and metal immobilization was greater for Cd (16%) than for Pb (12%) in co-spiked soils amended with low-temperature SCB. Biochar application improved microbial activity and biomass, and enzymatic activity in the soils co-spiked with metals, but these positive impacts of SCB were less pronounced in the co-spiked soils than in the single-spiked soils. SCB decreased the adverse impacts of heavy metals on soil properties largely through the enhanced labile C for microbial assimilation and partly through the immobilization of metals. Redundancy analysis further confirmed that soil OC was overwhelmingly the dominant driver of changes in the properties and quality of contaminated soils amended with SCB. The promotion of soil microbial quality by the low-temperature SCB was greater than by high-temperature SCB, due to its higher labile C fraction. Our findings showed that SCB at lower temperatures could be applied to metal co-polluted soils to mitigate the combined effects of metal stresses on microbial and biochemical functions.
Improving deep learning performance by using Explainable Artificial Intelligence (XAI) approaches
Authors: Bento Vitor , Kohler Manoela , Diaz Pedro , Mendoza Leonardo , Pacheco Marco Aurelio 
Published: October 2021

AbstractIn this work we propose a workflow to deal with overlaid images—images with superimposed text and company logos—, which is very common in underwater monitoring videos and surveillance camera footage. It is demonstrated that it is possible to use Explaining Artificial Intelligence to improve deep learning models performance for image classification tasks in general. A deep learning model trained to classify metal surface defect, which previously had a low performance, is then evaluated with Layer-wise relevance propagation—an Explaining Artificial Intelligence technique—to identify problems in a dataset that hinder the training of deep learning models in a wide range of applications. Thereafter, it is possible to remove this unwanted information from the dataset—using different approaches: from cutting part of the images to training a Generative Inpainting neural network model—and retrain the model with the new preprocessed images. This proposed methodology improved F1 score in 20% when compared to the original trained dataset, validating the proposed workflow.

Published: October 2021

AbstractObjectivesInternal carotid artery (ICA), the main artery of the brain, passes through the cavernous sinus (CS) which forms one of these venous pools. During this transition, while there is arterial blood in the lumen of ICA, its outer surface is in contact with venous blood from the brain. Herein, we aimed to detect the receptor differences of ICA in this highly specialized anatomical region of the skull base.MethodsWe performed the study on 10 human cadavers and searched CGRPR, TRP12, ASIC3 and ACTHR receptors via immunostaining using laser scanning confocal microscopy.ResultsWe determined TRP12 receptor positive in the tunica media and tunica adventitia layers of the cavernous segment of ICA. We did not detect similar positivity in the cervical part of the ICA. In the receptor scan we made in terms of CGRPR, while we detected positivity in the tunica media layer of the cavernous segment, we found positivity in the tunica intima layer of the cervicalis segment of the ICA. We did not detect any positivity for ASIC3 and ACTHR receptors in both parts of the ICA.ConclusionsAs a result, we observed various differences in receptors between ICA segments. While the outer surface of the ICA in the cervical region did not show any receptor positivity, we detected TRP12 receptor positivity along the tissue contour of vessel in the CS. We assume that it may provide a new perspective on pathologies of the CS/ICA and preservation of brain hemodynamics for clinicians.
L’effacement de la laïcité libérale en France. De la séparation du politique et du religieux vers la promotion du « vivre‑ensemble »
Authors: Valentin Vincent 
Published: October 2021

RésuméDepuis plusieurs décennies, la laïcité subit en France une transformation profonde qui remet en cause sa dimension libérale. Le principe de séparation du politique et du religieux se dilue au profit de la promotion de la notion récente du « vivre‑ensemble », qui voudrait associer garantie de la liberté religieuse et défense des valeurs républicaines. Ce processus d’érosion s’appuie sur le développement d’une logique concordataire et sur l’émergence d’une conception « communautariste » de la laïcité.

Abstract
Optical parametric chirped-pulse amplification implemented using multikilojoule Nd:glass pump lasers is a promising approach for producing ultra-intense pulses (>1023 W/cm2). We report on the MTW-OPAL Laser System, an optical parametric amplifier line (OPAL) pumped by the Nd:doped portion of the multi-terawatt (MTW) laser. This midscale prototype was designed to produce 0.5-PW pulses with technologies scalable to tens of petawatts. Technology choices made for MTW-OPAL were guided by the longer-term goal of two full-scale OPALs pumped by the OMEGA EP to produce 2 × 25-PW beams that would be co-located with kilojoule−nanosecond ultraviolet beams. Several MTW-OPAL campaigns that have been completed since “first light” in March 2020 show that the laser design is fundamentally sound, and optimization continues as we prepare for “first-focus” campaigns later this year.

AbstractBackground:In 2015, an international outbreak of Mycobacterium chimaera infections among patients undergoing cardiothoracic surgeries was associated with exposure to contaminated LivaNova 3T heater-cooler devices (HCDs). From June 2017 to October 2020, the Centers for Disease Control and Prevention was notified of 18 patients with M. chimaera infections who had undergone cardiothoracic surgeries at 2 hospitals in Kansas (14 patients) and California (4 patients); 17 had exposure to 3T HCDs. Whole-genome sequencing of the clinical and environmental isolates matched the global outbreak strain identified in 2015.Methods:Investigations were conducted at each hospital to determine the cause of ongoing infections. Investigative methods included query of microbiologic records to identify additional cases, medical chart review, observations of operating room setup, HCD use and maintenance practices, and collection of HCD and environmental samples.Results:Onsite observations identified deviations in the positioning and maintenance of the 3T HCDs from the US Food and Drug Administration (FDA) recommendations and the manufacturer’s updated cleaning and disinfection protocols. Additionally, most 3T HCDs had not undergone the recommended vacuum and sealing upgrades by the manufacturer to decrease the dispersal of M. chimaera–containing aerosols into the operating room, despite hospital requests to the manufacturer.Conclusions:These findings highlight the need for continued awareness of the risk of M. chimaera infections associated with 3T HCDs, even if the devices are newly manufactured. Hospitals should maintain vigilance in adhering to FDA recommendations and the manufacturer’s protocols and in identifying patients with potential M. chimaera infections with exposure to these devices.
Disambiguating language attitudes held towards sociodemographic groups and geographic areas in South East England
Authors: Cole Amanda 
Published: October 2021

AbstractUsing a novel, digitized method, this paper investigates the language attitudes of 18- to 33-year-olds in South East England. More broadly, this paper demonstrates that disambiguating the language attitudes held towards sociodemographic groups and geographic areas is paramount to understanding the configuration of language attitudes in an area, particularly for areas with high cultural and linguistic heterogeneity. A total of 194 respondents evaluated the speech of 102 other south-eastern speakers. Results reveal an imperfect mapping between language attitudes held towards geographic areas and speakers from these areas. Although East London and Essex are the most negatively evaluated areas, speakers’ demographic and identity data is the primary factor conditioning language attitudes. Across South East England, working-class and/or ethnic minority speakers, as well as those who identify their accent in geographically marked terms, are evaluated most negatively, which is compounded if they are from East London or Essex.
BETWEEN CHAOS AND COSMOS: TONY WEIR IN THE CAMBRIDGE LAW JOURNAL
Authors: McBride Nicholas J. 
Published: October 2021

AbstractThis article surveys Tony Weir's case notes and book reviews for the Cambridge Law Journal between 1963 and 2002 in order to illuminate Tony's unique genius as a legal academic and thinker. Reading Tony's case notes and book reviews reveals that he cannot be characterised as either a “lumper” (someone who seeks to reduce the law down to a few elemental ideas and concepts) or as a “splitter” (someone who resists such a reduction). Instead, Tony's genius lay in his possessing the Keatsian quality of “negative capability”. This quality allowed Tony to be both a lumper and a splitter at the same time, refusing to identify himself definitively with either way of thinking about the law.
THE “ENGLISH SCHOOL” OF INTERNATIONAL LAW: SOUNDINGS VIA THE 1972 JUBILEE ESSAYS
Authors: Ranganathan Surabhi 
Published: October 2021

AbstractAs part of the Cambridge Law Journal's centenary celebrations, this article reads two essays from the journal's 50th anniversary issue. The essays, by Cambridge professors Robert Jennings and Derek Bowett offer resources for the history of international law and its historiography. They shine a light on key debates on the law of the sea at a crucial moment of its development. A close reading of these essays also reveals starting points for new scrutiny of an “English” tradition of international law, including the place of the academy within the tradition, its blueprints for the future of international law and international legal order, and its relation to empire and capitalism.

AbstractObjective:To evaluate the properties of the cognitive battery used in the MIND Diet Intervention to Prevent Alzheimer’s Disease. The MIND Diet Intervention is a randomized control trial to determine the relative effectiveness of the MIND diet in slowing cognitive decline and reducing brain atrophy in older adults at risk for Alzheimer’s dementia.Methods:The MIND cognitive function battery was administered at baseline to 604 participants of an average age of 70 years, who agreed to participate in the diet intervention study, and was designed to measure change over time. The battery included 12 cognitive tests, measuring the 4 cognitive domains of executive function, perceptual speed, episodic memory, and semantic memory. We conducted a principal component analysis to examine the consistency between our theoretical domains and the statistical performance of participants in each domain. To further establish the validity of each domain, we regressed the domain scores against a late-life cognitive activity score, controlling for age, race, sex, and years of education.Results:Four factors emerged in the principal component analyses that were similar to the theoretical domains. In regression equations, we found the expected associations with age, education, and late-life cognitive activity with each of the four cognitive domains.Conclusions:These results indicate that the MIND cognitive battery is a comprehensive and valid battery of four separate domains of cognitive function that can be used in diet intervention trials for older adults.

AbstractObjective:To investigate the association between ultra-processed food (UPF) consumption and internalising symptoms (IS) among adolescents.Design:It is a cross-sectional study. Paper-pencil survey was completed in classroom with information on UPF consumption, IS and selected covariates. IS were assessed with the Internalizing Symptoms sub-scale from the Social Behaviour Questionnaire (IS-SBQ). UPF was evaluated with a FFQ extracted from the Brazilian National School Health Survey. Crude and adjusted association between UPF and IS was investigated with structural equation models.Setting:São Paulo, SP, Brazil.Participants:A total of 2680 students, Mage = 14·85; (95 % CI 14·81, 14·88).Results:UPF consumption was associated with higher scores in IS in the crude (β = 0·14; P < 0·001) and adjusted (β = 0·12; P < 0·001) models. The higher the consumption of UPF, the higher is the IS score. The following variables were associated with a lower risk of UPF consumption: male sex, public school and having more meals with parents. The change in the magnitude of the standardised score was almost negligible, but the model was significantly improved with the inclusion of covariates.Conclusions:Our results provide evidence about the positive association between UPF consumption and IS among adolescents. The association, despite its low magnitude, remained significant after adjusting for potential confounders. These results are relevant considering the increase in UPF consumption worldwide and in low- and middle-income countries. Also, our study emphasises the importance of a healthy diet with a reduction in UPF consumption among adolescents.
Best Practices for Analysis of Carbon Fibers by Atom Probe Tomography
Authors: Johansen Marcus , Liu Fang 
Published: October 2021

AbstractCarbon fiber technology drives significant development in lightweight and multifunctional applications. However, the microstructure of carbon fibers is not completely understood. A big challenge is to obtain the distribution of heteroatoms, for instance nitrogen, with high spatial resolution in three dimensions. Atom probe tomography (APT) has the potential to meet this challenge, but APT of carbon fibers is still relatively unexplored. We performed APT on three types of carbon fibers, including one high modulus type and two intermediate modulus types. Here, we present the methods to interpret the complex mass spectra of carbon fibers, enhance the mass resolution, and increase the obtained analysis volume. Finally, the origin of multiple hit events and possible methods to mitigate multiple hit events are also discussed. This paper provides guidance for future APT studies on carbon fibers, and thus leads the way to a deeper understanding of the microstructure, and consequently advancements in wide applications of carbon fibers.
Indigenous Australian laws of war: Makarrata, milwerangel and junkarti
Authors: White Samuel , Kerkhove Ray 
Published: October 2021

AbstractStudies in Australian history have lamentably neglected the military traditions of First Australians prior to European contact. This is due largely to a combination of academic and social bigotry, and loss of Indigenous knowledge after settlement. Thankfully, the situation is beginning to change, in no small part due to the growing literature surrounding the Frontier Wars of Australia. All aspects of Indigenous customs and norms are now beginning to receive a balanced analysis. Yet, very little has ever been written on the laws, customs and norms that regulated Indigenous Australian collective armed conflicts. This paper, co-written by a military legal practitioner and an ethno-historian, uses early accounts to reconstruct ten laws of war evidently recognized across much of pre-settlement Australia. The study is a preliminary one, aiming to stimulate further research and debate in this neglected field, which has only recently been explored in international relations.
Fourteen‐Year Acceleration Along the Japan Trench

Published: October 2021

AbstractAn acceleration of the background seismicity and a shortening of the slow slip events recurrence intervals in the Boso peninsula (Japan) suggest a slow unlocking of the Philippine Sea‐North America (PHS‐NAM) subduction interface from 1990 to 2011. Motivated by these previous observations, we used GPS (Global Positioning System) time series to study the 1997–2011 evolution of interface locking offshore Honshu with a specific focus on the Kanto region. We newly processed the GPS data in double difference and analyzed them with a trajectory model that accounts for seismic and aseismic variations, and that includes an inter‐seismic acceleration term. We inverted the surface acceleration obtained, on both the Pacific‐North America (PAC‐NAM) and the PHS‐NAM interfaces. The inverted slip rate changes over time compare well with previous studies: we infer slip deceleration between –N and acceleration between –N (PAC‐NAM), with a maximum amplitude of 1.75 mm/ corresponding to an equivalent geodetic locking change of 0.3 over the 14 years. More notably, our analysis reveals a novel and robust slip acceleration South of N that we interpret as an unlocking of the PAC‐NAM interface. It is located noticeably far from the 2011 Tohoku earthquake rupture and is therefore unlikely connected to it. The slip acceleration inverted from the surface displacements is comparable to the changes observed in the seismicity rate. Our results further demonstrate that inter‐seismic slip rate can significantly evolve over years to decades, and suggest a simple relationship between the seismicity and the slip on the subduction interface.
