Abstract:
Purpose This paper aims to present the spherical entropy image (SEI), a novel global descriptor for the scan registration of three-dimensional (3D) point clouds. This paper also introduces a global feature-less scan registration strategy based on SEI. It is advantageous for 3D data processing in the scenarios such as mobile robotics and reverse engineering. Design/methodology/approach The descriptor works through representing the scan by a spherical function named SEI, whose properties allow to decompose the six-dimensional transformation into 3D rotation and 3D translation. The 3D rotation is estimated by the generalized convolution theorem based on the spherical Fourier transform of SEI. Then, the translation recovery is determined by phase only matched filtering. Findings No explicit features and planar segments should be contained in the input data of the method. The experimental results illustrate the parameter independence, high reliability and efficiency of the novel algorithm in registration of feature-less scans. Originality/value A novel global descriptor (SEI) for the scan registration of 3D point clouds is presented. It inherits both descriptive power of signature-based methods and robustness of histogram-based methods. A high reliability and efficiency registration method of scans based on SEI is also demonstrated.

Abstract:
Abstract. Four degrees of freedom (4DoF) registration is a class of point cloud registration problems for finding a rigid transformation to align two point clouds under the constraint that the rigid transformation is composed of a three-dimensional (3D) translation and 1D rotation. This constraint is suitable to align scan pairs acquired using modern terrestrial Light Detection and Ranging (LiDAR) scanners, the scans of which can share the direction of gravity as the Z-axis due to such scanners using tripods or internal inclinometers. We propose a fast convergence method for global optimal 4DoF registration. The proposed method consists of (i) our newly developed 4DoF registration model formulated as an optimization problem involving the cylindrical norm to measure the distance between two points, and (ii) a fast convergence algorithm to find a global optimal solution of the model. We experimentally demonstrated that the proposed method reduced the number of iterations to convergence and computation time compared with a current 4DoF registration method, especially when the given scan pairs are similar but cannot be aligned, which often appears in registration of multiple point clouds.

Abstract:
Density functional theory (DFT) is used extensively for the first-principles calculation of hyperfine coupling constants in both main-group and transition metal systems. As with many other properties, the performance of DFT for hyperfine coupling constants is of variable quality, particularly for transition metal complexes, because it strongly depends on the nature of the chemical system and the type of approximation to the exchange-correlation functional. Recently, a meta-generalized-gradient approximation (mGGA) functional was proposed that obeys all known exact constraints for such a method, known as the Strongly Constrained and Appropriately Normed (SCAN) functional. In view of its theoretically superior formulation a benchmark set of complexes is used to assess the performance of SCAN for the challenging case of transition metal hyperfine coupling constants. In addition, two global hybrid versions of the functional, SCANh and SCAN0, are described and tested. The values computed with the new functionals are compared with experiment and with those of other DFT approximations. Although the original SCAN and the SCAN-based hybrids may offer improved hyperfine coupling constants for specific systems, no uniform improvement is observed. On the contrary, there are specific cases where the new functionals fail badly due to a flawed description of the underlying electronic structure. Therefore, despite these methodological advances, systematically accurate and system-independent prediction of transition metal hyperfine coupling constants with DFT remains an unmet challenge.

Abstract:
Cette thèse traite de la question de l’authenticité des photographies d’identité, partie intégrante des documents nécessaires lors d’un contrôle d’accès. Alors que les moyens de reproduction sophistiqués sont accessibles au grand public, de nouvelles méthodes / techniques doivent empêcher toute falsification / reproduction non autorisée de la photographie d’identité. Cette thèse propose une méthode de hachage pour l’authentification de photographies d’identité, robuste à l’impression-lecture. Ce travail met ainsi l’accent sur les effets de la numérisation au niveau de hachage. L’algorithme mis au point procède à une réduction de dimension, basée sur l’analyse en composantes indépendantes (ICA). Dans la phase d’apprentissage, le sous-espace de projection est obtenu en appliquant l’ICA puis réduit selon une stratégie de sélection entropique originale. Dans l’étape d’extraction, les coefficients obtenus après projection de l’image d’identité sur le sous-espace sont quantifiés et binarisés pour obtenir la valeur de hachage. L’étude révèle les effets du bruit de balayage intervenant lors de la numérisation des photographies d’identité sur les valeurs de hachage et montre que la méthode proposée est robuste à l’attaque d’impression-lecture. L’approche suivie en se focalisant sur le hachage robuste d’une classe restreinte d’images (d’identité) se distingue des approches classiques qui adressent une image quelconque
This thesis addresses the question of the authenticity of identity photographs, part of the documents required in controlled access. Since sophisticated means of reproduction are publicly available, new methods / techniques should prevent tampering and unauthorized reproduction of the photograph. This thesis proposes a hashing method for the authentication of the identity photographs, robust to print-and-scan. This study focuses also on the effects of digitization at hash level. The developed algorithm performs a dimension reduction, based on independent component analysis (ICA). In the learning stage, the subspace projection is obtained by applying ICA and then reduced according to an original entropic selection strategy. In the extraction stage, the coefficients obtained after projecting the identity image on the subspace are quantified and binarized to obtain the hash value. The study reveals the effects of the scanning noise on the hash values of the identity photographs and shows that the proposed method is robust to the print-and-scan attack. The approach focusing on robust hashing of a restricted class of images (identity) differs from classical approaches that address any image

Abstract:
A voz é a principal ferramenta de comunicação da espécie humana e quase 70% da população economicamente ativa dos países desenvolvidos dependem direta ou indiretamente dela em sua profissão. Sua produção deve-se ao funcionamento harmônico de sistemas fisiológicos distintos, nos quais a laringe desempenha um importante papel. É nela que as funções de deglutição, respiração e fonação se encontram e também onde o pulso glotal é formado durante a passagem do ar pelas pregas vocais. Se os nervos e músculos da região por alguma razão são lesionados, o funcionamento dessas funções é prejudicado, causando sérios danos à qualidade de vida do indivíduo. Em virtude disso, diversas pesquisas tem sido realizadas visando adquirir informações que auxiliem as tomadas de decisões clínicas e cirúrgicas. Embora diversos avanços tenham sido realizados no campo de modelagens das pregas vocais e nos estudos da laringe, modelos baseados em geometrias de pacientes específicos que possam colaborar mais ativamente no planejamento cirúrgico, permanecem um desafio. Nesse sentido, este trabalho apresenta o desenvolvimento de um modelo computacional tridimensional, com base em imagens de tomografia computacional. Tendo por objetivo impulsionar a modelagem das características fisiológicas de pacientes reais e assim proporcionar maiores informações para tomadas de decisões. Esse modelo foi utilizado em simulações de escoamento de fluido solucionadas por elementos finitos, apresentando possibilidades satisfatórias de contribuir para avanços na modelagem de pacientes com patologias e em abordagens interativas, tal como interferências nos modelos virtuais por interfaces hápticas e simulações virtuais de cirurgia da laringe.
The voice is the main instrument for communication of human beings and almost 70% of the economically active population in the developed countries depends, directly or indirectly, on it for their profession. Its production is due to the harmonious interaction of different physiological systems, in which the larynx plays an important role. The larynx is involved in the deglutition, breathing and phonation functions and it is where the glottal pulse is formed during airflow through the vocal folds. If the nerves and muscles in this region for some reason are injured, this functions are adversely affected, causing serious damages to the individuals quality of life. As a result, several researches have been carried out, aiming at acquiring information that help in the clinical and surgical decision making. Although many progresses had been reached in the field of vocal folds modeling and in larynx studies, patientspecific geometry modeling that may take an active part in the surgical planning are still a challenge. In this regard, this work presents the development of a threedimensional computational model, based on images from computed tomography (CT) scans. This model was used in fluid flow simulations, solved by finite element analysis, showing satisfactory possibilities for contributions to progresses in the modeling of patients with lesions and in interactive approaches, such as interferences in the models with haptic interface and virtual surgery of the larynx.

Abstract:
Les chutes de pierres sont l'un des processus géomorphologiques les plus courants dans les milieux à forte pente. Malgré leur volume limité, les chutes de pierres constituent un danger important, en raison de leur évolution rapide, de leur vitesse élevée et de l'énergie d'impact. Leur caractère imprévisible peut être problématique lorsque l'on souhaite étudier en détail leur dynamique et leurs facteurs de déclenchement dans des conditions naturelles. L'influence relative des précipitations, de la fonte des neiges, de la température ou des cycles de gel-dégel est depuis longtemps reconnue, notamment grâce à des méthodes de surveillance des parois à moyen terme. A très haute altitude, des relations sans équivoque ont été établies entre l'augmentation de l'activité des chutes de pierres, le dégel du pergélisol et le réchauffement climatique. En revanche, en dessous de la limite du pergélisol, la rareté persistante de bases de données exhaustives et précises rend nos connaissances encore lacunaires. Au cours des deux dernières décennies, la dendrogéomorphologie - une approche basée sur l'analyse des dommages infligés aux arbres après des impacts d'éboulement - a été utilisée pour combler certaines limites inhérentes aux archives historiques. Paradoxalement, ces reconstitutions n'ont que rarement été comparées aux données climatiques afin de déterminer précisément les facteurs météorologiques déclencheurs ou pour détecter les influences du réchauffement climatique sur l'activité des chutes de pierres.Dans ce contexte, cette thèse vise à proposer des recommandations méthodologiques pour optimiser les stratégies d'échantillonnage afin de quantifier précisément les incertitudes des reconstructions dendrogéomorphologiques dans le temps. Nos résultats montrent que la cartographie à haute résolution des tiges sur les sites étudiés combinée à une sélection rigoureuse des espèces d'arbres situées à proximité des falaises améliore la robustesse des reconstitutions sur les parcelles étudiées à Saint-Guillaume (peuplement forestier mixte, massif du Vercors, Alpes françaises) et à Valdrôme (peuplements forestiers monospécifiques plantés, massif du Diois, Alpes françaises).Dans un second temps, nous nous servons des reconstructions obtenues et des réanalyses SAFRAN pour identifier les déclencheurs météorologiques des événements de chutes de pierres. A l'échelle interannuelle, nos résultats montrent que les précipitations estivales et les événements pluvieux intenses sont les principaux facteurs de l'activité des chutes de pierres sur les deux sites, alors qu'aucun impact clair des températures ou des cycles de gel-dégel n'a pu être détecté.Enfin, nous comparons les fluctuations décennales existantes dans les deux reconstructions dendrogéomorphologiques avec les séries climatiques disponibles pour la période 1959-2017, dans le but de détecter les impacts potentiels du réchauffement climatique sur l'activité des chutes de pierres. Dans le massif du Vercors, nous expliquons l'augmentation de l'activité des chutes de pierres observée depuis 1959 par une recolonisation forestière rapide et par la sur-représentation des jeunes arbres, plus sensibles, plutôt que par le changement climatique. Dans le massif du Diois, l'absence de tendance significative suggère qu'une légère augmentation de l'activité n'est pas soutenu par les données existantes. Cependant, la faible robustesse des modèles de régression multiple utilisés ici, l'augmentation limitée de la température sur les sites d'étude et le caractère incomplet de nos reconstructions dendrogémorphologiques suggèrent que ces résultats doivent être traités avec prudence.Au total, cette thèse démontre clairement la valeur ajoutée de la dendrogéomorphologique pour reconstruire l'activité passée des chutes de pierres, évaluer les conditions météorologiques propices aux déclenchement de cet aléa et détecter les impacts potentiels des changements environnementaux sur la dynamique des processus
Rockfalls are one of the most common geomorphological processes in the steeply sloping environments. Despite their limited volumes, rockfalls pose a significant hazard, due to their rapid evolution, high velocity and impact energy, but their unpredictable occurrence hinders detailed investigation of their dynamics and drivers under natural conditions. As the relative influence of rainfall, snowmelt, temperature, or freeze–thaw cycles have long been identified, based on medium-term monitoring methods, as the main drivers of rockfall activity, increasing rockfall hazards triggered by climate change are a major concern expressed both in scientific and non-scientific media.At high altitude sites, unequivocal relationships have been established between heightened rockfall activity, permafrost thawing and global warming. By contrast, below the permafrost limit, in the absence of longer-term assessments of rockfall triggers and possible changes thereof, our knowledge of rockfall dynamics remains still lacunary as a result of the persisting scarcity of exhaustive and precise rockfall databases.Over the last two decades, dendrogeomorphology – based on the analysis of damage inflicted to trees after rockfall impacts – has been used to overcome certain limitations inherent to historical archives and reconstructions of rockfall activity have been developed. Paradoxically, tree-ring reconstructions have only rarely been compared with climatic data to precisely constrain the potential meteorological triggers of process activity or to detect potential influences of global warming mostly due to the absence of clear recommendations to derive reconstructions that optimally capture the climatic signal in rockfall-prone environments.In this context, this PhD thesis first aims at proposing clear methodological guidelines to optimize sampling strategies of trees so as to precisely quantify uncertainties in dendrogeomorphic reconstructions back in time. Our results clearly evidence that the high-resolution mapping of stems on the studied combined with a careful selection of tree-species located at the vicinity of the cliffs improve the robustness of our reconstructions at the Saint-Guillaume (mixed forest stand, Vercors massif, French Alps) and Valdrôme (monospecific planted forest stands, Diois massif, French Alps) studied plots.In the second part, we capitalize on rockfall activity derived from optimized reconstructions and on the high-spatio-temporal resolution of the SAFRAN reanalyses, to precisely identify the meteorological triggers of rockfall events. At the interannual scale, our results evidence that summer precipitations and intense rainfall-events are the main drivers at both sites while no clear impact of temperature or freeze-thaw cycles could be detected.Finally, we compare decadal fluctuations existing in both tree-ring records with climatic series available for the period 1959-2017 with the purpose to detect the potential impacts of global warming on rockfall activity. In the Vercors massif, we explain increasing rockfall activity observed in the reconstruction since 1959 by a rapid forest recolonization and the overrepresentation of young sensitive trees rather than by climate change. In the Diois massif, the absence of significant trend suggests that a premature warning of increasing rockfall hazard, is not supported by the existing data. Yet, the weak robustness of the multiple regression models used here, the limited increase of temperature at the study sites and the incompleteness of our tree-ring reconstructions suggest that these results have to be treated with cautiously. All in all, this PhD thesis clearly demonstrates the added-value of the dendrogeomorphic approach to reconstruct rockfall activity, assess the meteorological driver of past events as well as to detect the potential impacts of environmental changes on the process dynamics

Abstract:
We look at global scans of the parameter space of Two-Higgs-Doublet Models (2HDMs). Our first study is a Bayesian analysis of the Yukawa Z₂-aligned 2HDMs: the type-I, type-II, type-X (lepton-specific) and type-Y (flipped) models. Incorporated into these analyses are the theoretical constraints: perturbativity checks, the stability of the potential and the unitarity of the scattering matrix (up to NLO). The generic potential couplings are run up to 1 TeV, stability and perturbativity are then rechecked at this upper bound. We also calculate loop corrections to the scalar masses and check that they do not grow too large. Next, we apply experimental constraints. These include Higgs signals and searches matched to the latest data from LEP, the Tevatron and the LHC. As well as fits onto the electroweak precision parameters and an array of flavour processes, notably the radiative B decays and the R(k) and R(*)(k) anomalies. Our second study is a frequentist analysis of the most general 2HDM (or type-III model), searching for limits on flavour changing quark decays. The most general 2HDM introduces flavour-changing currents (FCC). We apply a subset of the theoretical and the experimental bounds described above (at tree-level) and work with a restricted Yukawa sector. The restricted Yukawa sector allows FCC only between fermions and then only between the second and third generation. The flavour analysis focuses on the discrepancy in the B(0)(s)-meson mass splitting with the Standard Model (SM) and leads us to explore how this process may be better fit by a 2HDM.

Abstract:
The Pictorial Art of El Greco: Transmaterialities, Temporalities, and Media investigates El Greco’s pictorial art as foundational to the globalising trends manifested in the visual culture of early modernity. It also exposes the figurative, semantic, and allegorical senses that El Greco created to challenge an Italian Renaissance-centered discourse. Even though he was guided by the unprecedented burgeoning of devotional art in the post-Tridentine decades and by the expressive possibilities of earlier religious artifacts, especially those inherited from the apostolic past, the author demonstrates that El Greco forged his own independent trajectory. While his paintings have been studied in relation to the Italian and Spanish school traditions, his pictorial art in a global Mediterranean context continues to receive scant attention. Taking a global perspective as its focus, the book sheds new light on El Greco’s highly original contribution to early Mediterranean and multi-institutional configurations of the Christian faith in Byzantium, Venice, Rome, Toledo, and Madrid.

Full text
Abstract:
In sickle cell anaemia (SCA) a single mutation in the haemoglobin beta-globin gene is responsible for a pleomorphic phenotype leading to acute and chronic life-threatening complications. Healthcare management programmes, patient and family education, infection prophylaxis (especially in childhood), and long-term treatment for some patients (such as hydroxyurea) have significantly improved survival, giving rise to some new long-term issues.Sickle cell-associated nephropathy (SCAN) leads in some cases to chronic renal failure with a significant impact on survival. SCAN is characterized by an increased effective plasma renal flow and glomerular filtration rate, glomerular hypertrophy, and damaged vasa recta system leading to albuminuria and impaired urinary concentration.Early onset of hyperfiltration occurs in 60% of SCA patients often associated with microalbuminuria. SCAN risk factors are still under investigation, but may be related to chronic haemolysis at an early time point. Other lesions in patients with sickle cell anaemia include papillary necrosis, and recurrent acute kidney injury in association with crises or infections.ACEI are recommended if there is proteinuria. There is no current agreement on whether angiotensin-converting enzyme inhibitors (ACEI) should be introduced earlier, but systematic screening for microalbuminuria and hypertension, and avoidance of nephrotoxic agents are strongly advised.Patients with sickle cell trait (carriers for sickle cell anaemia) are prone to microscopic haematuria and abnormalities of the vasa recta have been described. A very rare tumour, renal medullary carcinoma, is largely restricted to this group (in whom it is still extremely rare). Increased risk of other renal problems is still largely hypothetical rather than proven.The prevalence of nephropathies in other sickle cell diseases (in particular haemoglobin SC disease) is much lower.

Abstract:
This chapter addresses the troubling legacies left by the global financial crisis: rising government debt burdens and slower economic growth prospects. In October 2009, debt burdens were surging at about an equal pace in the United States and in the euro area. However, growth prospects looked better in the U.S. than in the euro area because the U.S. Federal Reserve had proactively stimulated its economy while the European Central Bank (ECB) had kept monetary policy tight. Policymakers faced a dilemma. Solving the debt problem required governments to undertake austerity measures—raise taxes and reduce spending; but austerity would lower the demand for goods and services, which would cause incomes to fall and further set back growth prospects. Hence, some, including the International Monetary Fund's Research Department, believed it was important to jump-start economic growth.

Since its earliest assessments of NHRIs in 1998, the Global Alliance of NHRIs’ (GANHRI) Sub-Committee on Accreditation (SCA) has developed a substantive body of work that has examined the operation and practice of over 128 institutions in countries and territories from every part of the globe. Analysed and catalogued in their entirety into an accessible format for the first time, and covering all aspects of NHRIs’ structure and functioning, as well as providing a comprehensive overview of how the SCA works in practice, this book is an indispensable resource for scholars and practitioners who wish to understand and learn how NHRIs operate at the national level, as well as what problems they face and ultimately, how they can be strengthened. Benefitting from the unique insight of David Langtry, a member of the SCA for eleven years, this book is an essential source for all those interested in the role of NHRIs, and more broadly, of all state-established institutions intended to function independently.

Abstract:
AbstractIn the space of a few weeks in 2020, the rapid spread of the COVID-19 virus into a global pandemic has changed the way we work, live, interact and communicate with one another. One highly unexpected result of the massive rise in homeworking has been an extraordinary exposure of domestic bookshelves, which in the famous words of Amanda Hess, have become the “quarantine’s hottest accessory” (New York Times, May 1, 2020). Personal bookshelves had hitherto been jealously guarded, a marker for personal taste and shared only with the select few invited into their owners’ households and allowed to scan the titles on display. This physically delimited space has now been unleashed upon the world: where once few people could look at the books on our shelves, now theoretically, almost everyone can. The pandemic bookshelf has accidently been fashioned into the most ubiquitous liminal zone anywhere: it is the ostensibly private and personal backdrop for the staging of our public, digitally mediated, professional existence. Drawing upon theoretical perspectives from anthropology, psychology and literary theory, this chapter explores the many ways in which the private-public bookshelf has become the cultural liminal space par excellence during the COVID-19 pandemic.

Abstract:
AbstractThis chapter is the introduction to the volume on social protection in Brazil, India, China, and South Africa. The Introduction outlines an ideational and historical approach to social protection in the Global South to contribute to a theory of “social policy in development contexts”, which is a desideratum. The Introduction also provides basic data on the four countries (Brazil, India, China, and South Africa) and summaries of all the chapters in the book. Three research gaps are identified: scarcity of historical research; scant attention to ideas and instead a dominant focus on interests; and insufficient use of historical sources. This volume contributes to filling these gaps through a historical, idea-centred, and source-based approach. A multi-layered model of social ideas—the “onion skin model”—is developed that has the “social question” as its pivot.

Abstract:
This paper presents a grid-based scan-to-map matching technique for accurate simultaneous localization and mapping (SLAM). At every acquisition of a new scan, the proposed technique estimates the relative position from which the previous scan was taken, and further corrects its estimation error by matching the new scan to the globally defined map. In order to achieve best scan-to-map matching at each acquisition, the map to match is represented as a grid map with multiple normal distributions (NDs) in each cell. Additionally, the new scan is also represented by NDs, developing a novel ND-to-ND matching technique. The ND-to-ND matching technique has significant potential in the enhancement of the global matching as well as the computational efficiency. Experimental results first show that the proposed technique successfully matches new scans to the map generating very small position and orientation errors, and then demonstrates the effectiveness of the multi-ND representation in comparison to the single-ND representation.

Taking into Account the Potential Effects of Counterterrorism Measures on Humanitarian and Medical Activities: Elements of an Analytical Framework for States Grounded in Respect for International Law.

Abstract:
For at least a decade, States, humanitarian bodies, and civil-society actors have raised concerns about how certain counterterrorism measures can prevent or impede humanitarian and medical activities in armed conflicts. In 2019, the issue drew the attention of the world’s preeminent body charged with maintaining or restoring international peace and security: the United Nations Security Council. In two resolutions — Resolution 2462 (2019) and Resolution 2482 (2019) — adopted that year, the Security Council urged States to take into account the potential effects of certain counterterrorism measures on exclusively humanitarian activities, including medical activities, that are carried out by impartial humanitarian actors in a manner consistent with international humanitarian law (IHL). By implicitly recognizing that measures adopted to achieve one policy objective (countering terrorism) can impair or prevent another policy objective (safeguarding humanitarian and medical activities), the Security Council elevated taking into account the potential effects of certain counterterrorism measures on exclusively humanitarian activities to an issue implicating international peace and security. In this legal briefing, we aim to support the development of an analytical framework through which a State may seek to devise and administer a system to take into account the potential effects of counterterrorism measures on humanitarian and medical activities. Our primary intended audience includes the people involved in creating or administering a “take into account” system and in developing relevant laws and policies. Our analysis zooms in on Resolution 2462 (2019) and Resolution 2482 (2019) and focuses on grounding the framework in respect for international law, notably the U.N. Charter and IHL. In section 1, we introduce the impetus, objectives, and structure of the briefing. In our view, a thorough legal analysis of the relevant resolutions in their wider context is a crucial element to laying the conditions conducive to the development and administration of an effective “take into account” system. Further, the stakes and timeliness of the issue, the Security Council’s implicit recognition of a potential tension between measures adopted to achieve different policy objectives, and the relatively scant salient direct practice and scholarship on elements pertinent to “take into account” systems also compelled us to engage in original legal analysis, with a focus on public international law and IHL. In section 2, as a primer for readers unfamiliar with the core issues, we briefly outline humanitarian and medical activities and counterterrorism measures. Then we highlight a range of possible effects of the latter on the former. Concerning armed conflict, humanitarian activities aim primarily to provide relief to and protection for people affected by the conflict whose needs are unmet, whereas medical activities aim primarily to provide care for wounded and sick persons, including the enemy. Meanwhile, for at least several decades, States have sought to prevent and suppress acts of terrorism and punish those who commit, attempt to commit, or otherwise support acts of terrorism. Under the rubric of countering terrorism, States have taken an increasingly broad and diverse array of actions at the global, regional, and national levels. A growing body of qualitative and quantitative evidence documents how certain measures designed and applied to counter terrorism can impede or prevent humanitarian and medical activities in armed conflicts. In a nutshell, counterterrorism measures may lead to diminished or complete lack of access by humanitarian and medical actors to the persons affected by an armed conflict that is also characterized as a counterterrorism context, or those measures may adversely affect the scope, amount, or quality of humanitarian and medical services provided to such persons. The diverse array of detrimental effects of certain counterterrorism measures on humanitarian and medical activities may be grouped into several cross-cutting categories, including operational, financial, security, legal, and reputational effects. In section 3, we explain some of the key legal aspects of humanitarian and medical activities and counterterrorism measures. States have developed IHL as the primary body of international law applicable to acts and omissions connected with an armed conflict. IHL lays down several rights and obligations relating to a broad spectrum of humanitarian and medical activities pertaining to armed conflicts. A violation of an applicable IHL provision related to humanitarian or medical activities may engage the international legal responsibility of a State or an individual. Meanwhile, at the international level, there is no single, comprehensive body of counterterrorism laws. However, States have developed a collection of treaties to pursue specific anti-terrorism objectives. Further, for its part, the Security Council has assumed an increasingly prominent role in countering terrorism, including by adopting decisions that U.N. Member States must accept and carry out under the U.N. Charter. Some counterterrorism measures are designed and applied in a manner that implicitly or expressly “carves out” particular safeguards — typically in the form of limited exceptions or exemptions — for certain humanitarian or medical activities or actors. Yet most counterterrorism measures do not include such safeguards. In section 4, which constitutes the bulk of our original legal analysis, we closely evaluate the two resolutions in which the Security Council urged States to take into account the effects of (certain) counterterrorism measures on humanitarian and medical activities. We set the stage by summarizing some aspects of the legal relations between Security Council acts and IHL provisions pertaining to humanitarian and medical activities. We then analyze the status, consequences, and content of several substantive elements of the resolutions and what they may entail for States seeking to counter terrorism and safeguard humanitarian and medical activities. Among the elements that we evaluate are: the Security Council’s new notion of a prohibited financial “benefit” for terrorists as it may relate to humanitarian and medical activities; the Council’s demand that States comply with IHL obligations while countering terrorism; and the constituent parts of the Council’s notion of a “take into account” system. In section 5, we set out some potential elements of an analytical framework through which a State may seek to develop and administer its “take into account” system in line with Resolution 2462 (2019) and Resolution 2482 (2019). In terms of its object and purpose, a “take into account” system may aim to secure respect for international law, notably the U.N. Charter and IHL pertaining to humanitarian and medical activities. In addition, the system may seek to safeguard humanitarian and medical activities in armed conflicts that also qualify as counterterrorism contexts. We also identify two sets of preconditions arguably necessary for a State to anticipate and address relevant potential effects through the development and execution of its “take into account” system. Finally, we suggest three sets of attributes that a “take into account” system may need to embody to achieve its aims: utilizing a State-wide approach, focusing on potential effects, and including default principles and rules to help guide implementation. In section 6, we briefly conclude. In our view, jointly pursuing the policy objectives of countering terrorism and safeguarding humanitarian and medical activities presents several opportunities, challenges, and complexities. International law does not necessarily provide ready-made answers to all of the difficult questions in this area. Yet devising and executing a “take into account” system provides a State significant opportunities to safeguard humanitarian and medical activities and counter terrorism while securing greater respect for international law.
