On the study of cellular automata on modulo-recurrent words
Moussa Barro, K. Ernest Bognini and Boucaré Kientéga
In this paper, we study some class of cellular automata (CA) preserving modulo-recursive, stability by reflection and richness called stable cellular automata (SCA). After applying these automata on Sturmian words, we establish some combinatorial properties of these new words. Next, the classical and palindromic complexity functions of these w(...)

How do climate and land use affect structural attributes, diversity and carbon sequestration at both vegetation and species levels in West African savanna ecosystems?
Valaire Séraphin Ouehoudja Yaro, Loyapin Bondé, Pawend-taoré Christian Bougma, Reginald Tang Guuroh, Oumarou Ouédraogo & Anja Linstädter
Research on land use impacts on woody diversity and carbon stocks in West African savannas has primarily focused on the vegetation level. However, a combined analysis at both vegetation and species levels offers a more nuanced understanding of carbon loss patterns and provides stronger guidance for management and conservation of threatened spe(...)

Influence of seed size and pretreatments on Faidherbia albida (apple‑ring) seed germination in Burkina Faso
Innocent Charles Emmanuel Traoré, Bossila Séraphin Hien, Valaire Séraphin Ouehoudja Yaro, Alhassane Zaré, Marie Louise Kaboré, Blaise Kabré, Loyapin Bondé & Oumarou Ouédraogo
Faidherbia albida (Delile) A. Chev. is a key agroforestry species that provides multiple ecosystem services, including soil fertilization, carbon sequestration, and forage production. Despite its ecological importance in climate change mitigation and its vital role for rural communities, natural populations of F. albida are declining due to po(...)

Media campaigns, early diagnosis, isolation and treatment on bacterial meningitis outbreak prevention: A modeling study
Ousmane Koutou, Wendkouni Ouedraogo, Hamidou Ouedraogo, Komi Afassinou, Abou Bakari Diabate
Bacterial meningitis is a severe infection affecting the protective membranes of the brain and spinal cord, with rapidly worsening symptoms that can lead to life-threatening complications. This study presents an autonomous deterministic epidemic model, SIaIsMRS, to explore the dynamics of bacterial meningitis in a community implementing contro(...)

Copulas approach for modeling the stochastic dependence of three physico- chemical components of groundwater in the province of Sissili (Burkina Faso)
Fabrice Ouoba, Vini Yves Bernadin Loyara, Sibiri Narcisse Dolemweogo and Diakarya Barro
This study aims to model the stochastic dependence between potassium (K+), iron (F e2+), and ammonium (N H+4 ) concentrations in groundwater from the
Sissili province in Burkina Faso. To achieve this, we rely on the Student, Frank, and H ¨usler–Reiss copulas to capture the full range of hydro-geochemical dependence structures. This statistica(...)

Être archéologue aujourd’hui : fouilles, responsabilités administratives, gestion du patrimoine culturel
Simporé Lassina
L’exploration du passé par les fouilles n’est plus le seul objectif de l’archéologie contemporaine. Cette dernière s’inscrit de plus en plus dans un cadre élargi, où se croisent exigences scientifiques, contraintes administratives, enjeux patrimoniaux et responsabilités éthiques. Cet article propose une réflexion théorique sur la figure de l’a(...)

Privileged Complexity of the ternary Thue-Morse word
Boucaré Kientéga, K. Ernest Bognini and Moussa Barro
In this paper, we focus on a new type of complexity of infinite words called privileged complexity. We apply this concept to the ternary Thue-Morse word. First, we present properties of the return words in the ternary Thue-Morse word. Then, we study the privileged words of this infinite word. Finally, we derive a recursive formula that allows(...)

Anti-biofilm, anti-quorum sensing potential, cytotoxicity, and UPLC-UV/DAD-MS/MS/QTOF profiling of Prosopis Africana (Guill. & Perr.) Taub. leaves and stems extracts: benefits of a traditional medicine in dental care
Bance Alimata, Rouamba Ablassé, Compaoré Moussa, Compaoré Eli, Kabré W.M.E Leila, Ouedraogo Noufou, Hay A. Emmanuelle, Kiendrebeogo Martin & Dijoux-Franca Marie-Geneviève
Background
Prosopis africana is traditionally used in folk medicine in Burkina Faso for oral diseases. Leaves and stems are used in rural areas to treat dental caries, and the bark is used to treat green diarrhea in infants. In the context of a better understanding of Prosopis africana’s bioactivity and toxicity, the present study deals with(...)

Optimizing the 4G--5G Migration: A Simulation-Driven Roadmap for Emerging Markets
Desire Guel and Justin Pegd-Windé Kouraogo and Kouka Kouakou Nakoulma
Deploying fifth-generation (5G) networks in emerging markets demands a balance between performance targets and constraints in budget, spectrum, and infrastructure. We use MATLAB simulations to quantify how radio and architectural levers - MIMO (beamforming, diversity, spatial multiplexing), carrier aggregation (CA), targeted spectrum refarming(...)

Fusarium solani is a cosmopolitan fungus causing mortality of young cowpea plants and severe wilting at an advanced stage of plant development. As a result, it considerably affects cowpea production, undermining food and nutritional security. The use of resistant varieties combined with appropriate agricultural practices is a very effective an(...)

Raymond Nana, Hugues Roméo Bazié, Assan Gnoumou, Pale Mini Dah, Martin Sawadogo, and Gerard Zombré
Flemingia faginea is a woody species whose various parts are widely used in traditional medicine. However, this species, which typically grows along waterways, is becoming increasingly rare due to poor seed germination in the wild, possibly resulting from the effects of climate change and human activities. Given the increasing rarity of F. fag(...)

Aims: Pearl millet (Pennisetum glaucum (L.) R. Br.) is one of the cross-pollinated cereals in West Africa. It is cultivated for its grains. However, to date, strategies for selecting pearl millet populations and hybrids are low in West Africa. The objective of this study is to characterize the genetic bases of parental and F1 populations of pe(...)

A mathematical model study with crowley-Martin functional responses to describe fish and zooplankton dynamics
Wendkouni Ouedraogo, Hamidou Ouedraogo, Ousmane Koutou, Boureima Sangare
In this paper, we consider a reaction-diffusion model with homogeneous Neumann
boundary conditions to describe fish and zooplankton dynamics. This model incorporates
a complex Crowley-Martin functional responses. We also introduce two important
elements: fishing and cannibalism effect in the dynamics. In the mathematical
analysis, global a(...)
