Pan‑C2(n+1): A Theoretical Prediction for 2D Carbon Allotropes
Xin-Qi Liu, Ang Ma, Ya-Nan Zhang, Zhi-Jun Yi, Roberts I. Eglitis, Issa Tapsoba, Ran Jia
In this work, the two-dimensional (2D) periodic armchair nanoribbon (pan-C2(n+1)) systems have been proposed and investigated by using the density functional theory (DFT). The pan-C2(n+1) systems can be easily obtained by in-plane rotating the carbon pairs C2 at certain positions in the monolayer graphene (G). The graphene nanoribbon patterns(...)

Local perceptions of ginger ( Zingiber officinale Roscoe) crop management in Burkina Faso
Korotimi Deme, Moumouni Konate, Mahamadi Hamed Ouedraogo, Lardia Ali Bougma, Mahamadou Sawadogo
Ginger (Zingiber officinale Rosc., Zingiberaceae) is a highly profitable crop of great interest to growers and processors. However, there is an insufficiency of knowledge about the production practices implemented in the main production areas. This study described farmers' knowledge of ginger diversity, production constraints, tuber conservati(...)

Epidemiological profile of HIV/AIDS at The Outpatient Treatment Centre, Nouakchott, Mauritania, 2010-2019
Mohamedou Hmeied Maham1,2, Pauline Kishwendsida Yanogo2,3, Djibrill Barry2, Yoda Hermann2, Abderrahman Baye6, Boushab Mohamed Boushab2,5, Ousmane Boua Togola2,4, Nicholas Meda2,3.
In response to the HIV/AIDS pandemic, many countries have established surveillance systems
to collect data to monitor disease progression and the impact of control measures. In Mauritania,
HIV/AIDS surveillance data are collected and stored at the Outpatient Treatment Centre in the AMNIR
CHIVA database. We analyzed the database to establish(...)

Revisiting the Non-Determinism of Code Generation by the GPT-3.5 Large Language Model
Salimata Sawadogo, Aminata Sabané, Rodrique Kafando, Tegawendé F. Bissyandé
Despite recent advancements in Large Language Models (LLMs) for code generation, their inherent non-determinism remains a significant obstacle for reliable and reproducible software engineering research. Prior work has highlighted the high degree of variability in LLM-generated code, even when prompted with identical inputs. This non-determini(...)

Physicochemical and Mineralogical Characterizations of Two Natural Laterites from Burkina Faso: Assessing Their Potential Usage as Adsorbent Materials
Corneille Bakouan, Louise Chenoy, Boubié Guel, and Anne-Lise Hantson
In the framework of lateritic material valorization, we demonstrated how the geological environment determines the mineralogical characterizations of two laterite samples,
KN and LA. KN and LA originate from the Birimian and Precambrian environments, respectively. We showed that the geological criterion alone does not determine the applicabil(...)

How Many Goats Does a Mannequin Cost? Community-engaged Design of Layperson First Responder Training Materials in Low-resource Settings
Hannah B Wild, Moumini Niaone, Aparna Cheran, Madeline Ross, Barclay T Stewart, Nicolas Meda
Objectives
Simulation materials for layperson first responder (LFR) trainings used in high-resource settings are prohibitively expensive for use in low- and low-middle income countries. To date, no structured approach to community-engaged design in identifying accessible and acceptable simulation materials for LFR trainings has been developed(...)

Analysis of gold mineralization in the Gnimi-Yabogane B zone, in the com-
mune of Dano in southwest Burkina Faso, within the Boromo greenstone belt,
reveals local geology comprising volcano-sedimentary rocks, meta-andesite,
amphibolitic gabbros, and granodiorites. The study highlighted three phases
of deformation (D1, D2, D3), with mine(...)
