1. A Journey into Matrix Analysis

Author

Bourin, Jean-Christophe

Subjects
Mathematics - Functional Analysis, Mathematics - Numerical Analysis, Mathematics - Operator Algebras
Abstract

This is the Habilitation Thesis manuscript presented at Besan\c{c}on on January 5, focusing on Matrix Analysis, Matrix Inequalities and Matrix Decompositions. There are also some topics in (Hilbert space) Operator Theory. The text should be of interest for a large audience of researchers and students in pure and applied mathematics. We may divide it into five parts: 1) Chapter 1 is an introductory chapter, some results from the period 1999-2010 are given, and a few conjectures are proposed. 2) Chapters 2-4 deal with matrix inequalities, Chapter 2 is concerned with norm inequalities and logmajorization and Chapters 3-4 with functional calculus and a unitary orbit technique that I started to develop in 2003. 3) Chapter 5 is a time-break in infinite dimensional Hilbert space operators, the essential numerical range plays a key role. 4) Chapters 6-8 establish several decompositions for partitioned matrices, especially for positive block matrices. Some norm inequalities involving the numerical range are derived. 5) Chapter 9 may be of special interest for students : a proof of the Spectral Theorem for bounded operators is derived from the matrix case., Comment: 144 pages. This is the Habilitation Thesis manuscript presented at Besan\c{c}on on January 5. Special thanks are due to my colleagues and friends kindly acting as rewievers, Frank Hansen, Hideki Kosaki, and Fedor Sukochev

Abstract

Une problématique majeure de la filière avicole est l’absence de valorisation des frères des poules pondeuses, du fait de leur faible rendement en viande. Ce constat, qui questionne l’éthique de la production, concerne 50 millions de poussins mâles en France et 7,5 milliards dans le monde, ces animaux étant jusqu’à récemment, éliminés après sexage et tri à l’éclosion. Cette prise de conscience, largement médiatisée ces dernières années, a conduit à la publication d’un décret, le 5 février 2022, interdisant la mise à mort des mâles des lignées de l’espèce Gallus gallus destinées à la production des œufs de consommation. Trois alternatives ont été proposées depuis les premières réflexions sur le sujet : 1) élever les frères de pondeuses et identifier des marchés de valorisation, 2) créer de nouveaux croisements génétiques entre souches « Chair » et souches « Ponte » où les descendantes femelles seraient valorisées pour les œufs et les descendants mâles pour leur viande (souches « mixtes »), et 3) développer des outils de sexage in ovo (ou ovosexage) pour détecter puis éliminer les œufs contenant un embryon mâle avant éclosion. Cette dernière approche est la seule viable techniquement et économiquement parlant, et utilisable par la filière actuellement. Elle réunit de nombreux atouts, en termes de faisabilité pour la mise en œuvre dans les couvoirs, et d’acceptabilité à la fois par le consommateur, le citoyen et les professionnels. Cette revue fait le point sur le contexte socio-économique et les techniques d’ovosexage actuellement disponibles, tout en introduisant quelques repères physiologiques d’embryologie aviaire qui permettent de mieux comprendre les contraintes associées au développement de techniques à des stades précoces de développement.

14. A Pythagorean theorem for partitioned matrices.

Author

Bourin, Jean-Christophe and Lee, Eun-Young

Subjects
*MATRIX inequalities, *ABSOLUTE value, *CALCULUS
Abstract

We establish a Pythagorean theorem for the absolute values of the blocks of a partitioned matrix. This leads to a series of remarkable operator inequalities. For instance, if the matrix \mathbb {A} is partitioned into three blocks A,B,C, then \begin{gather*} |\mathbb {A}|^3 \ge U|A|^3U^* + V|B|^3V^*+ W|C|^3W^*,\\ \sqrt {3} |\mathbb {A}| \ge U|A|U^* + V|B|V^*+ W|C|W^*, \end{gather*} for some isometries U,V,W, and \begin{equation*} \mu _4^2(\mathbb {A}) \le \mu _3^2(A) +\mu _2^2(B) + \mu _1^2(C) \end{equation*} where \mu _j stands for the j-th singular value. Our theorem may be used to extend a result by Bhatia and Kittaneh for the Schatten p-norms and to give a singular value version of Cauchy's Interlacing Theorem. [ABSTRACT FROM AUTHOR]

24. Attention Deficit Hyperactivity Disorder (ADHD) in Adults: A Mini Review

Author

Michel Bourin

Abstract

Attention Deficit Hyperactivity Disorder (ADHD) is not exclusively limited to childhood and adolescence, but it often persists in adults, where its prevalence in the general population is estimated at around 4% to 5%. It is accompanied by significant psychological, social and professionals. It is essential to ensure the detection of this disorder in adults. Indeed, psychostimulants have demonstrated therapeutic efficacy by numerous controlled studies. ADHD treatment should have the primary objective of improving attentional abilities and reducing impulsive behavior.

Abstract

Bipolar disorder is a chronic illness, defined by a succession of depressive and/or manic periods separated by free intervals. Its evolution with aging is marked by a high suicide mortality rate. Bipolar disorders raise the question of their evolution when the age of the subject, in particular with regard to their frequency, their clinical characteristics, their prognosis and their management. The evolution of bipolar disorder with aging poses several difficulties in clinical practice due to its underestimated frequency and its misleading presentation and in particular by the presence of sometimes significant cognitive alterations leading sometimes to dementia.

26. Vascular Dementia: Definitions, Origins, Symptoms, Diagnosis and Treatments

Author

Michel Bourin

Abstract

Vascular dementia corresponding to intellectual degradation significant enough to disrupt daily life, attributed to cerebral lesions of vascular origin. They are the second cause of dementia after Alzheimer's disease in the defeated countries. Their diagnosis is made difficult, on the one hand by the diversity of lesions potentially responsible for cognitive disorders and on the other hand by their frequent association with Alzheimer's disease. No treatment, other than preventive treatment, has been validated in vascular dementia. Several concepts have attempted or are attempting to characterize vascular dementias ("multiple infarct dementias", "vascular cognitive impairment", "vascular cognitive impairment").

Abstract

The INTAQT project aims to characterize the links between husbandry systems and the quality of poultry meat, beef and dairy products after consulting at national and Europea levels the actors of each sector on their expectations. The first step was to identify their perceptions and points of view in terms of product quality and this communication focuses on results obtained with producers, processors, retailers and some representatives of citizens’ associations. In addition to the intrinsic quality criteria already foreseen in the project (health, nutrition, organoleptic), stakeholders spontaneously expressed the importance of considering extrinsic criteria related to sustainability (animal welfare, environment, socio-economic aspects) as well as technological quality. The other criteria were mentioned in a variable way depending on the type of stakeholder, the country and the sector concerned. These results are consistent with consumers’ views and they have been taken into account to include other quality criteria in the project.

Abstract

Agri-food chain actors (AFAs) lack reliable information to meet consumer expectations in relation to multiple facets of intrinsic quality of chicken meat, beef, and dairy products from the various European livestock systems. One of the challenges of the INTAQT project is to build, with AFAs, multi-criteria scoring tools related to products global quality. This tool should combine safety, sensory, and nutritional results obtained during the project-based on collection of poultry/beef/dairy samples and possibly other quality criteria. Multi-actor participatory approach was applied to present and discuss the concept of a multicriteria scoring tool, collecting opinions, fears, and expectations on this tool. On a consumer side, it was felt that such a multi-criteria score placed on products could be a clear and simple representation of a complex reality. However, some disadvantages were expressed about its reliability or implementation. For their part, AFAs had varying opinions on the tool’s target, mainly about its possible use as an internal tool or for consumer information, with different pros and cons expressed on both aims. Fears dealt with the building of the tool, and its relevance, representativeness, practical use, and the potential dangers, especially if safety aspects were included. However, both consumers and AFAs agree on the need to include in this tool extrinsic criteria such as farming system sustainability and animal welfare.

Abstract

The INTAQT project aims to establish the relationship between intrinsic and extrinsic quality criteria of animal products and European husbandry systems. Another aim is to evaluate the impact of innovative husbandry practices on the quality of the products. In order to determine, which husbandry systems and practices the project should study, a European-wide stakeholder consultation of the chicken, beef and dairy value chains was conducted. Stakeholders were presented with a preselection of husbandry systems and were requested to modify or add systems according to their interest, and to name innovative practices to be tested. In total, 161 face-to-face interviews took place between October 2021 and March 2022, followed by 12 national and 3 European group meetings. Overall, stakeholders of all value chains were satisfied with the initially selected systems. Suggestions covered both mainstream systems as well as new, innovative ones, which are emerging due to the growing societal rejection of intensive farming practices. These included systems that improve the farms’ self-autonomy, use local resources or a circular economy, or improve animal welfare and environmental impact. Similarly, actors in all three value chains suggested innovative practices that centre on increased animal welfare and environmental sustainability, thus reflecting a willingness to respond to societal demands.

Abstract

Under the EU Air Quality Directive (AQD) 2008/50/EC member states are required to undertake routine monitoring of PM2.5 composition at background stations. The AQD states for PM2.5 speciation this should include at least: nitrate (NO3−), sulfate (SO42−), chloride (Cl−), ammonium (NH4+), sodium (Na+), potassium (K+), magnesium (Mg2+), calcium (Ca2+), elemental carbon (EC) and organic carbon (OC). Until 2017, it was the responsibility of each country to determine the methodology used to report the composition for the inorganic components of PM2.5. In August 2017 a European standard method of measurement of PM2.5 inorganic chemical components (NO3−, SO42−, Cl−, NH4+, Na+, K+, Mg2+, Ca2+) as deposited on filters (EN16913:2017) was published. From August 2019 this then became the European standard method. This filter method is labour-intensive and provides limited time resolution and is prone to losses of volatile compounds. There is therefore increasing interest in the use of alternative automated methods. For example, the UK reports hourly PM2.5 chemical composition using the Monitor for AeRosols and Gases in Ambient air (MARGA, Metrohm, NL). This study is a pre-assessment review of available data to demonstrate if or to what extent equivalence is possible using either the MARGA or other available automatic methods, including the Aerosol Chemical Speciation Monitor (ACSM, Aerodyne Research Inc. US) and the Ambient Ion Monitor (AIM, URG, US). To demonstrate equivalence three objectives were to be met. The first two objectives focused on data capture and were met by all three instruments. The third objective was to have less than a 50% expanded uncertainty compared to the reference method for each species. Analysis of this objective was carried out using existing paired datasets available from different regions around the world. It was found that the MARGA (2006–2019 model) had the potential to demonstrate equivalence for all species in the standard, though it was only t

Abstract

Atmospheric particulate matter with an aerodynamic diameter < 2.5 µm (PM2.5) is associated with adverse effects on the climate system, the human health, vegetation and the ecosystems. The World Health Organization (WHO) lowered the guideline limit for PM2.5 in autumn 2021 and this is exceeded in many regions including rural and remote areas in mainland Europe. Measurements of the chemical composition of PM2.5 is essential to assess the sources which contribute to PM2.5 mass concentrations and to further design meaningful policies to tackle sources at their origin.Here we report 6 years (2014- 2020) of PM2.5 mass and chemical speciation at five remote sites across France belonging to the EMEP network (European Monitoring and Evaluation Programme). The seasonal and spatial variability of aerosol composition and source contributions based on the proximity of sources and long-range transport are discussed. Trends in PM2.5 and the main components at the five locations were evaluated by means of random-forest modelling coupled with a de-weathering algorithm. This approach is advantageous as resulting trends are driven by changes in emission or atmospheric processes and not by changes in weather conditions and/or long-range transport patterns. Random-forest regression modelling was built using meteorological data, backtrajectory information and temporal variables at each site and quantified the most important factors that explain PM2.5 concentrations at remote rural areas in France.All sites observed statistically significant downward trends in PM2.5 at a rate of -4 to -9% year-1 for the period 2014 – 2020. The decrease in PM2.5 concentrations was mostly explained by changes in the secondary inorganic species (sulphate, nitrate and ammonium) and not by changes in primary PM2.5 emissions. The variability in trends in PM2.5 and components observed across the sites is discussed with their implications for policy makers.

Abstract

Ammonia (NH3) is the major alkaline gas in the atmosphere and the third most abundant N-containing species, after N2 and N2O. It plays an important role in N deposition processes, responsible of several damages on ecosystems, and it is also a precursor of fine particulate matter, known to cause numerous impacts on human health. Despite this, not many countries have implemented long-term monitoring of NH3 in their air quality programs due to the lack of consensus on limit values for ambient levels and a reference method of measuring this gas. In the climate change context, governments and health organizations are increasingly concerned about NH3 and its effects. As a proof, the revision of the EU air quality directives proposes the inclusion of NH3 as a mandatory pollutant for several urban and rural supersites for all member states.Currently, there are only 12 long term programs worldwide dedicated specifically to measure NH3 or including gas-phase measurements of NH3. The longest NH3 time series come from UK and Africa, where measurements start in mid-1990. The rest of locations have started after 2000 and they have lower temporal coverage, between 5 and 22 years. The objectives pursued by these networks are to follow long term spatio-temporal trends, assess the N deposition on sensitive ecosystems, validate emission and/or chemistry transport models and help to understand the effectiveness of air pollution control and mitigation policies. Most of these networks operate using a combination of low-cost samplers with a high spatial density with few collocated sites with high time resolution instrumentation to help calibrate passive samplers and to better monitor the fine temporal variability of NH3. This combined approach has proven to be successful for most of the proposed objectives.However, there are several differences that may difficult harmonizing the information at both the technical and scientific level. At the technical level these include type and number of passive samplers per site, calibration protocol, data control and quality analysis, exposure duration and type of high time resolution sampling method. On the scientific level, increased difficulty understanding the operative parameters and scientific results may come from language barriers (non-English reports), availability of the data (whether it is public or not), and gaps on the knowledge of NH3 levels on a spatial scale due to differences in the implementation of monitoring strategies within the same country.This work aims to review synthetically the world current long-term NH3 networks and provide some insight and recommendations for other countries and supranational programs aiming to establish long term monitoring networks of NH3, based on cost-effective, technical, and operational criteria.

Abstract

International audience; This paper looks at experiential feedback and the technical and scientific challenges tied to the MERITE-HIPPOCAMPE cruise that took place in the Mediterranean Sea in spring 2019. This cruise proposes an innovative approach to investigate the accumulation and transfer of inorganic and organic contaminants within the planktonic food webs. We present detailed information on how the cruise worked, including 1) the cruise track and sampling stations, 2) the overall strategy, based mainly on the collection of plankton, suspended particles and water at the deep chlorophyll maximum, and the separation of these particles and planktonic organisms into various size fractions, as well as the collection of atmospheric deposition, 3) the operations performed and material used at each station, and 4) the sequence of operations and main parameters analysed. The paper also provides the main environmental conditions that were prevailing during the campaign. Lastly, we present the types of articles produced based on work completed by the cruise that are part of this special issue.
