description: Multicellular organisms arise from a single fertilized zygote, which must contain all information necessary to develop. As the embryo divides, the cells adopt distinct functional characteristics, and as they do so, they become committed to these fates, unable in most cases to convert from one identity to another. Though it has been well known and described for over a century now this year, this latter process, in this work referred to as cell fate restriction, is not well understood. In this thesis, I aim to contribute to the understanding of this developmental phenomenon. The tool I use is the ectopic expression of a terminal fate specifying transcription factor, CHE-1. This transcription factor normally functions to specify the fate of a pair of gustatory neurons in the nematode Caenorhabditis elegans. If ectopically expressed early in development, it is able to induce expression of its target genes, but by adulthood, most cells are refractory to its transcriptional activation, evidence of developmental cell fate restriction in most tissues of the animal. I first describe the work of Tulsi Patel to which I contributed, in which an RNAi screen revealed that PRC2 complex is responsible for preventing CHE-1 activity in the germline cells of C. elegans. I then describe a semi-clonal genetic screen in which I found many more mutants with a similar phenotype affecting germline cells, and cloned another gene that is able to induce expression specifically in the epidermis of the animals: usp-48, a highly conserved ubiquitous nuclear deubiquitinating enzyme. Next, I describe another screen where I ectopically express CHE-1 specifically in the adult epidermis, in which I found and cloned an additional six mutants: ogt-1, dot-1.1, pmk-1, sek-1, nhr-48, and C08A9.6, here named epco-1. In this screen I also isolated but was unable to clone an additional four mutants that likely represent an additional four genes. I discuss the nature of these genes and their potential roles in restricting cell fate. Lastly, I describe the optimization of a tissue-specific transcriptional profiling protocol, INTACT, for use in the characterization of the mutants. With this optimized protocol, I was able to perform detailed RNAseq on two individual neuron types from the animal, as well as wild-type epidermis. This optimized protocol will be used to characterize the mutants in the future. Together, these results tie unexpected genes to the function of cell fate restriction in the C. elegans epidermis, which will aid in our understanding of this fundamental developmental phenomenon.

description: Assuming dislocations could be meaningfully described by torsion, we propose here a scenario based on the role of time in the low-energy regime of two-dimensional Dirac materials, for which coupling of the fully antisymmetric component of the torsion with the emergent spinor is not necessarily zero. Appropriate inclusion of time is our proposal to overcome well-known geometrical obstructions to such a program, that stopped further research of this kind. In particular, our approach is based on the realization of an exotic $time-loop$, that could be seen as oscillating particle-hole pairs. Although this is a theoretical paper, we moved the first steps toward testing the realization of these scenarios, by envisaging $Gedankenexperiments$ on the interplay between an external electromagnetic field (to excite the pair particle-hole and realize the time-loops), and a suitable distribution of dislocations described as torsion (responsible for the measurable holonomy in the time-loop, hence a current). Our general analysis here establishes that we need to move to a nonlinear response regime. We then conclude by pointing to recent results from the interaction laser-graphene that could be used to look for manifestations of the torsion-induced holonomy of the time-loop, e.g., as specific patterns of suppression/generation of higher harmonics.

description: This paper sets out the research agenda of the Kolleg-Forschergruppe “The Transformative Power of Europe. The European Union and the Diffusion of Ideas”. The diffusion of ideas has become a central research theme in political science, sociology, law, history, and economics. In this context, the Kolleg-Forschergruppe focuses on the theoretical and methodological challenges of identifying scope conditions for and interaction effects between the various causal mechanisms by which ideas are spread across time and space. We concentrate on the European Union (EU) as an almost ideal laboratory for investigating processes and outcomes of diffusion. First, European integration itself can be described as an effort to promote the diffusion of ideas across Europe and beyond. Second, European societies and polities emulate each other through mimetic processes. Third, Europe and the EU also serve as active promoters of diffusion processes toward the outside world. Last not least, European integration is embedded in and responds to larger global diffusion processes. The Kolleg-Forschergruppe will explore the diffusion of ideas in three thematic areas: “identity and the public sphere,” “compliance, conditionality, and beyond,” and “comparative regionalism and Europe’s external relations”.

Cell Size Control in Fission Yeast

description: Among all living organisms, there is almost much variety in cell size as there is for cell function and cell type. However, within each cell type, cells stay remarkably faithful to a defined size over generations. Many factors have been found to influence this ability to specify and maintain cell size, yet clear mechanisms have yet to be elucidated. The fission yeast Schizosaccharomyces pombe is an ideal model organism whose simple but conserved cell biology has led to the identification of many important cell size regulators common to all eukaryotes. In this thesis, I have quantitatively analyzed the dynamics and localization of several key players of cell size regulation, which lead to a new physical model on cell size regulation based on the localization and accumulation of a size sensing kinase cdr2p. In this model, cdr2p molecules accumulate in proportion to cell size into complexes called midsomes, which localize to the cortex at the central section of the cell. Upon reaching the desired cell size, cdr2p accumulation surpasses a concentration threshold and the cell will divide. This accumulation is partly facilitated by the key negative regulator pom1p, which prevents midsome formation at the cell tip. Evidence also suggests that the ER serves a role in confining midsome localization to the medial plasma membrane, perhaps by providing a physical link to the nucleus. Together, this work elucidates a mechanistic understanding of how cell size can be determined and controlled.
Cell fate restriction in Caenorhabditis elegans is orchestrated by precise chromatin organization and transcription factor activity

description: The plasticity of cells in a multicellular organism is progressively lost during differentiation. This loss is reflected in studies involving the ectopic misexpression of fate-specifying or terminal selector transcription factors (TFs). These TFs can efficiently activate target genes in undifferentiated cells, but lose this ability as cells differentiate. While this phenomenon of cell fate restriction is widely observed, the mechanisms orchestrating it are poorly understood. In this thesis, I have used the ubiquitous overexpression of Zn-finger-TF CHE-1 as a tool to understand the mechanisms that restrict cell fate in Caenorhabditis elegans. When CHE-1 is ubiquitously expressed at embryonic stages, it activates target gene expression in many cell types, while in adults it can only act in a few neurons. To uncover factors that inhibit plasticity of all other adult cells, I first performed an RNAi screen against chromatin-associated factors. Using this approach I found that the removal of either the PRC2 complex, which deposits the H3K27me3 mark, or loss of proteins that indirectly regulate domains of H3K27me3, allows CHE-1 and two other terminal selector TFs to activate target genes in the germline. These data show that the correct distribution of H3K27me3 is crucial for the restriction of germ cell fate. I next took a candidate approach to identify genes that regulate fate restriction in other cell types. We hypothesized that terminal selector TFs themselves, in addition to specifying cellular identity by controlling large gene sets, may also act to inhibit plasticity. To test this, I first assayed the activity of CHE-1 in mutants of COE-TF unc-3, the terminal selector for a subset of cholinergic motor neurons (MNs). I found that in contrast to wildtype MNs, unc-3 mutant MNs remain plastic as CHE-1 can induce expression of target genes in these cells even at the adult stage. This phenotype is also observed in four of six additional terminal selector mutants tested. I further found that the removal of met-2, a protein required for H3K9 methylation, or mes-2, a PRC2 component, also makes differentiated cholinergic MNs amenable to the activity of CHE-1. Preliminary evidence suggests that met-2 may act in the same pathway as unc-3. These results raise the exciting possibility that selector TFs play a role in restricting cell fate by organizing the heterochromatin domains in differentiated cells. Overall, in this work I provide functional evidence to show that specific chromatin-modifying enzymes restrict the fate of germ cells and that both fate-specifying TFs and chromatin-modifying enzymes are required for the fate restriction in neurons.

      In Chapter 1, I provide an overview of the field of mechanobiology, with an emphasis on the implications of cell-extracellular matrix and cell-cell attachment on cell function. In Chapter 2, I present the aims of the thesis, with a focus on the two cell systems used in the projects described: human mesenchymal stem cells, and T cells. Then, Chapters 3-5 represent the main body of my thesis, where I present detailed descriptions of the projects that I worked on and that successfully made it into scientific publications or that are in preparation for publication. In Chapter 3, I analyze how matrix chemistry and substrate rigidity affect human mesenchymal stem cell morphology in the context of lineage differentiation, and speculate on potential mechanisms that cells use to sense local rigidity. In Chapter 4, I present a new substrate design that facilitates live visualization of the interface formed between a T cell and an antigen presenting cell, i.e. the immunological synapse, and discuss the impact of intercellular forces on T cell activation. In Chapter 5, I explore the molecular mechanism of Cas-L mechanical activation at the immunological synapse of T cells, and demonstrate how Cas-L regulates T cell activation in the context of an immune response. Finally, in Chapter 6, I lay down the main conclusions of the thesis, and discuss ongoing projects that directly follow up on the results of this thesis.

description: The out-of-time-ordered correlation (OTOC) and entanglement are two physically motivated and widely used probes of the "scrambling" of quantum information, a phenomenon that has drawn great interest recently in quantum gravity and many-body physics. We argue that the corresponding notions of scrambling can be fundamentally different, by proving an asymptotic separation between the time scales of the saturation of OTOC and that of entanglement entropy in a random quantum circuit model defined on graphs with a tight bottleneck, such as tree graphs. Our result counters the intuition that a random quantum circuit mixes in time proportional to the diameter of the underlying graph of interactions. It also provides a more rigorous justification for an argument in our previous work arXiv:1807.04363, that black holes may be slow information scramblers, which in turn relates to the black hole information problem. The bounds we obtained for OTOC are interesting in their own right in that they generalize previous studies of OTOC on lattices to the geometries on graphs in a rigorous and general fashion.

Abstract

This essay dismantles the illusion of space and time as objective containers or probabilistic axes. Instead, it reframes them as emergent phenomena arising from structured resonance — lawful, prime-anchored, phase-locked oscillations that breathe reality into form. In the CODES framework, time is not a dimension — it is the recursive compression and expansion of coherence, a breath rhythm nested within harmonic fields. Likewise, space is not a vacuum — it is the visible surface of prime-indexed phase interference, an echo lattice formed when coherence crosses itself.

Where classical physics saw geometry and probabilistic motion, CODES sees waveform memory and directional chirality. What we once called “the arrow of time” is reinterpreted as directional entropy gradient within breathing fields, and “distance” becomes nothing more than the delay between nested phase-lock events.

Probability is not fundamental — it is an epistemic residue of observing systems out of phase. Stochastic behavior arises only when coherence is either occluded or wounded. Collapse is not inherent — it is a field injury.

CODES replaces all such illusions by returning the universe to its true nature: not a machine, not a set of coordinates, but a song — recursive, structured, resonant.

Time breathes.

Space hums.

Reality is not located. It is tuned.

description: The renormalization of quantum field theory twists the antipode of a noncocommutative Hopf algebra of rooted trees, decorated by an infinite set of primitive divergences. The Hopf algebra of undecorated rooted trees, ${\cal H}_R$, generated by a single primitive divergence, solves a universal problem in Hochschild cohomology. It has two nontrivial closed Hopf subalgebras: the cocommutative subalgebra ${\cal H}_{\rm ladder}$ of pure ladder diagrams and the Connes-Moscovici noncocommutative subalgebra ${\cal H}_{\rm CM}$ of noncommutative geometry. These three Hopf algebras admit a bigrading by $n$, the number of nodes, and an index $k$ that specifies the degree of primitivity. In each case, we use iterations of the relevant coproduct to compute the dimensions of subspaces with modest values of $n$ and $k$ and infer a simple generating procedure for the remainder. The results for ${\cal H}_{\rm ladder}$ are familiar from the theory of partitions, while those for ${\cal H}_{\rm CM}$ involve novel transforms of partitions. Most beautiful is the bigrading of ${\cal H}_R$, the largest of the three. Thanks to Sloane's {\tt superseeker}, we discovered that it saturates all possible inequalities. We prove this by using the universal Hochschild-closed one-cocycle $B_+$, which plugs one set of divergences into another, and by generalizing the concept of natural growth beyond that entailed by the Connes-Moscovici case. We emphasize the yet greater challenge of handling the infinite set of decorations of realistic quantum field theory.

description: The critical function of the kidney is to regulate the body’s extracellular fluid volume to maintain homeostasis. When insults to the kidney occur, as in the case of kidney ischemia, the function of the kidney to filter metabolic wastes and reabsorb essential solutes is compromised, leading to a variety of clinical manifestations. Current metrics of kidney function are measured by the rise of a single analyte, the serum creatinine, which implies injury of the kidney tubule and its epithelial cells and is encapsulated by the term Acute Kidney Injury (AKI). Yet, creatinine does not specify the etiology, the cell type, or the molecular pathways that are affected by the acute decreases in kidney excretory function. During my thesis work, I hypothesized that there is a pathogenetic heterogeneity of kidney injury and a specificity of location, timing, and molecular mechanisms, unique to each of these three injury models: kidney ischemia, volume depletion, and urinary tract infection. Using genetic mouse models, RNA-sequencing, and a range of molecular biology techniques, I have found (1) kidney ischemia activates inflammatory responses, signal transduction pathways, and epithelial repair and reprogramming, that are not activated in volume depletion, (2) which in contrast, is a transient metabolic condition, inducing genes regulating energy metabolism that were reversible upon rehydration. Lastly, (3) I have found that urinary tract infection, particularly one that invades the kidney, involves a novel heme transport system in the collecting duct of the kidney, that may contribute to nutritional defenses against bacterial pathogens. Each of these findings is explored in specific aims and experiments, which I detail here in my thesis.
Cellular Fatty Acid Toxicity: Extrapolating Yeast Screens into Mammalian Models

description: Fatty acid deposition in non-adipose tissue leads to a cellular dysfunction known as lipotoxicity. Neutral lipid synthesis is known to protect against lipotoxicity but many additional pathways are likely to be integral in this process. In order to identify pathways protective against lipid induced cell death, we performed a genome-wide unsaturated fatty acid (UFA) sensitivity screen in yeast. Of the ~5,500 gene mutants tested, we identified 156 which resulted in sensitivity to growth on media containing palmitoleate. These genes identified many cellular processes, including vesicular trafficking, lipid metabolism and vacuolar protein sorting. Deletion of three members of the GET complex, a complex essential for tail anchored protein insertion into the ER, caused vulnerability to fatty acids. We went on to assess the role of GET3 in cellular lipid metabolism and found that ablation of GET3 results in a defect in vacuolar hydrolysis and a reduction in lipid droplet number; pathways which we hypothesize to be integrally related. Furthermore, a major goal of this study was to find mammalian genes playing an integral role in pathways of lipoprotection. Of the 156 gene deletions found to confer fatty acid sensitivity in yeast, 68 have been conserved in mammals. We demonstrate that two of these mammalian orthologs, ARV1and ASNA1, are vulnerable to fatty acid treatment upon knockdown in the MIN6 pancreatic beta-cell line. These mammalian genes, which were identified through the fatty acid sensitivity screen in yeast, are involved in lipid induced cellular dysfunction in pancreatic beta-cells and, in the case of ARV1, hepatocytes. Therefore, these genes likely play a role in the progression of the lipotoxic diseases; type 2 diabetes and nonalcoholic fatty liver disease.

description: We present a pedagogical introduction to Bose-Einstein condensation in traps with spherical symmetry, namely the spherical box and the thick shell, sometimes called bubble trap. In order to obtain the critical temperature for Bose-Einstein condensation, we describe how to calculate the cumulative state number and density of states in these geometries, using numerical and analytical (semi-classical) approaches. The differences in the results of both methods are a manifestation of Weyl's theorem, i.e., they reveal how the geometry of the trap (boundary condition) affects the number of the eigenstates counted. Using the same calculation procedure, we analyzed the impact of going from three-dimensions to two-dimensions, as we move from a thick shell to a two-dimensional shell. The temperature range we obtained, for most commonly used atomic species and reasonable confinement volumes, is compatible with current cold atom experiments, which demonstrates that these trapping potentials may be employed in experiments.

subject: violence

description: Victims occupy an important, though conceptually complicated, place within criminology. Along with the offender, their presence, in many cases, defines whether a crime has occurred. Yet, pervasive stereotypes that inaccurately characterise true or 'ideal' victims as weak, helpless, and blameless during crime relegate the victim to a predominately passive role during crime and overlook their capacity for agency. These stereotypes persist, in part, due to a lack of insight into how victims think, feel, and respond during crime. This knowledge gap not only contributes to the maintenance of negative stereotypes, but also limits our understanding of a victim's role and how victims shape and influence the nature and progression of crime. This thesis sought to address this knowledge gap by exploring the extent to which victims act with agency during physically assaultive crime (comprising domestic violence, sexual assault, and physical assault). The thesis drew on a combination of Social Cognitive Theory (SCT), rational choice perspectives, and the interpersonal circumplex (IPC) model of social interaction to guide and frame its analysis and interpretation of victim behaviour. In line with SCT, victim agency was defined as the extent to which victim behaviour reflects a conscious, deliberate, and intentional attempt to influence the crime in reference to some underlying, self-motivated goal. However, agency is only possible if victims are conscious, motivated, and have, or believe they have, the capability to achieve their goals (self-efficacy). Thus, the characteristics of the situation and/or victim experience were also deemed important for victim agency during crime. As such, this thesis adopted an inductive approach - examining how victims behave before exploring the reasons for their actions. [...]

description: Abstract — In situations where maximum load demand exceeds power generation capacity, frequency would drop during cases of overload; and if appropriate underfrequency load curtailment scheme is not put in place, it could cause permanent turbine damage or affect the expected working operation of electric equipment. Various existing works on load curtailment in power systems have been done to great effect using meta-heuristic and classical control techniques. This paper seeks to comparatively analyze the Fuzzy Logic, Fuzzy-PID and Neuro-Fuzzy (ANFIS) controllers and their contribution to achieving load curtailment in a Single Area Power System via continuous load control. The transfer function model of the power system and the design of the controllers are done using Simulink, MATLAB software. The controllers are designed to output power imbalance based on frequency deviation during various system overload conditions. They also shed loads continuously until frequency is restored within the safe operating range. Different cases of system overload are used to analyze the performance of the controllers. It is found that the Neuro-Fuzzy controller gives the most optimized result.

description: In this paper we study the regularity properties of certain maximal operators of convolution type at the endpoint $p=1$, when acting on radial data. In particular, for the heat flow maximal operator and the Poisson maximal operator, when the initial datum $u_0 \in W^{1,1}( \mathbb{R}^d)$ is a radial function, we show that the associated maximal function $u^*$ is weakly differentiable and $$\|\nabla u^*\|_{L^1(\mathbb{R}^d)} \lesssim_d \|\nabla u_0\|_{L^1(\mathbb{R}^d)}.$$ This establishes the analogue of a recent result of H. Luiro for the uncentered Hardy-Littlewood maximal operator, now in a centered setting with smooth kernels. In a second part of the paper, we establish similar gradient bounds for maximal operators on the sphere $\mathbb{S}^d$, when acting on polar functions. Our study includes the uncentered Hardy-Littlewood maximal operator, the heat flow maximal operator and the Poisson maximal operator on $\mathbb{S}^d$.

description: Cognitive models of social anxiety disorder (SAD) emphasize repetitive negative thinking as a prominent maintaining factor that occurs both before (anticipatory processing) and after (post-event processing) social-evaluative events. While evidence suggests that repetitive negative thinking is a maladaptive process that has damaging cognitive, behavioural, and affective consequences for those with SAD, the cognitive mechanisms thought to underlie ineffective control of attention on these modes of thought was unclear. Cognitive interference theories, such as attentional control theory, propose that high levels of anxiety negatively impact the processing efficiency on tasks that require high cognitive resources. Accordingly, this thesis aimed to elucidate the role of executive functions on repetitive negative thinking in social anxiety by employing a combination of self-report and experimental methodologies with social anxiety analogue samples. Studies 1A and 1B explored the correlational relationships between social anxiety, anticipatory processing and post-event processing, and attentional control, as an initial step prior to conducting experimental studies. Poorer total attentional control was associated with social anxiety in both studies and diminished attentional shifting was associated with increased levels of PEP, but not AP. Mediation modelling suggested that trait anxiety mediated the relationship between attentional shifting and PEP, and positive affect mediated the relationship between total attentional control and PEP. Drawing from attentional control theory, studies 2 and 3, manipulated both anticipatory processing (study 2) and post-event processing (study 3), to examine the underlying executive functions responsible for ineffective control of attention in anxiety (i.e., inhibition and shifting) using the mixed emotional saccade task. Both studies 2 and 3 did not demonstrate an anxiety-related effect on attentional control and were comparable in showing that both AP and PEP appear to have an adaptive component on attentional control for low socially anxious individuals as indicated by improved task performance. Taken together, these findings highlight that other potential factors may underlie anticipatory and post-event processing in social anxiety, which appear to be complex and interacting. For example, other potential contributing factors that underlie AP and PEP may include the role of motivation, manipulating the cognitive load of the task, self-control strength, and valence of AP and PEP thoughts. However, an examination of these factors was beyond the aim and scope of the current PhD research program and needs to be investigated in future research.

description: Los sistemas inteligentes autónomos (SIA) aprenden de su entorno formando teorías sobre cómo el ambiente reacciona a sus acciones. Estas teorías se pueden compartir con otros
agentes. Cada SIA utiliza las teorías que ha adquirido para planificar. Esto significa construir planes (secuencias de acciones) que le permitan alcanzar sus objetivos autopropuestos.
Para mejorar el desempeño de los SIA alcanzando sus objetivos, es necesario contar con un método que permita estimar la confiabilidad de los planes generados antes de su ejecución.
Este proceso se llama ponderación de planes, y ha sido aplicado con éxito en trabajos anteriores.
En esta tesis se propone un nuevo algoritmo de ponderación de planes con el objetivo de mejorar el rendimiento (porcentaje de planes exitosos), aumentar la generalidad del conocimiento adquirido y acelerar el proceso de aprendizaje

description: Abstract — In situations where maximum load demand exceeds power generation capacity, frequency would drop during cases of overload; and if appropriate underfrequency load curtailment scheme is not put in place, it could cause permanent turbine damage or affect the expected working operation of electric equipment. Various existing works on load curtailment in power systems have been done to great effect using meta-heuristic and classical control techniques. This paper seeks to comparatively analyze the Fuzzy Logic, Fuzzy-PID and Neuro-Fuzzy (ANFIS) controllers and their contribution to achieving load curtailment in a Single Area Power System via continuous load control. The transfer function model of the power system and the design of the controllers are done using Simulink, MATLAB software. The controllers are designed to output power imbalance based on frequency deviation during various system overload conditions. They also shed loads continuously until frequency is restored within the safe operating range. Different cases of system overload are used to analyze the performance of the controllers. It is found that the Neuro-Fuzzy controller gives the most optimized result.

description: Recently, the notion of topological phases of matter has been extended to higher-order incarnations, supporting gapless modes on even lower dimensional boundaries, such as corners and hinges. We here identify a collection of cubic spin-3/2 fermions with biquadratic touching of Kramers degenerate valence and conduction bands as a platform to strain-engineer higher-order topological (HOT) phases: external uniaxial strain gives birth to a HOT Dirac semimetal or an insulator, depending on its sign, featuring topological \emph{hinge} modes in the strain direction. The insulator in fact exhibits \emph{mixed} topology, and in addition supports edge modes on orthogonal planes. These outcomes are germane when the external strain is applied along one of the $C_{4v}$ or coordinate axes, as well as $C_{3v}$ or body-diagonal, directions. Our findings place HgTe, gray-Sn, 227 pyrochlore iridates and half-Heusler compounds at the frontier of strain-engineered electronic HOT phases.

description: Evolution of the concept known in the theoretical physics as the Renormalization Group (RG) is presented. The corresponding symmetry, that has been first introduced in QFT in mid-fifties, is a continuous symmetry of a solution with respect to transformation involving parameters (e.g., of boundary condition) specifying some particular solution. After short detour into Wilson's discrete semi-group, we follow the expansion of QFT RG and argue that the underlying transformation, being considered as a reparameterisation one, is closely related to the self-similarity property. It can be treated as its generalization, the Functional Self-similarity (FS). Then, we review the essential progress during the last decade of the FS concept in application to boundary value problem formulated in terms of differential equations. A summary of a regular approach recently devised for discovering the RG = FS symmetries with the help of the modern Lie group analysis and some of its applications are given. As a main physical illustration, we give application of new approach to solution for a problem of self-focusing laser beam in a non-linear medium.

description: With the introduction of the PSD2 regulation in the EU which established the Open Banking framework, a new window of opportunities has opened for banks and fintechs to explore and enrich Bank transaction descriptions with the aim of building a better understanding of customer behavior, while using this understanding to prevent fraud, reduce risks and offer more competitive and tailored services.
 And although the usage of natural language processing models and techniques has seen an incredible progress in various applications and domains over the past few years, custom applications based on domain-specific text corpus remain unaddressed especially in the banking sector.
 In this paper, we introduce a language-based Open Banking transaction classification system with a focus on the french market and french language text. The system encompasses data collection, labeling, preprocessing, modeling, and evaluation stages. Unlike previous studies that focus on general classification approaches, this system is specifically tailored to address the challenges posed by training a language model with a specialized text corpus (Banking data in the French context). By incorporating language-specific techniques and domain knowledge, the proposed system demonstrates enhanced performance and efficiency compared to generic approaches.
