Comparative analysis of gradient boosting and random forest regressors for nutrient prediction in smart agriculture

Accurate estimation of nutrient concentrations can support monitoring in hydroponic systems. This study compares Random Forest Regressor (RFR) and Gradient Boosting Regressor (GBR) for predicting nitrogen, phosphorus, and potassium from pH, electrical conductivity, temperature, a...

Effect of amaranth flatbread on maternal anthropometry during pregnancy: Evidence from a cluster-randomized controlled trial in Southern Ethiopia

Introduction Maternal undernutrition and iron deficiency anemia (IDA) remain major public health challenges in Ethiopia, contributing to adverse pregnancy outcomes and poor maternal health. Amaranth, a nutrient-dense pseudocereal, has demonstrated potential to improve maternal nu...

Effect of Water Stress and Cabbage Aphid Feeding on Ethiopian Mustard Brassica carinata Physiology

Water deficit represents a critical abiotic constraint that impairs fundamental physiological processes in plants.Water deficit as a single stressor influences aphid's performance indirectly through changes in plant physiology.The present study was conducted in a greenhouse to in...

Crop-fertilization interdependence in Ethiopian enset-based systems shapes soil fertility and constrains crop expansion

Most agricultural soils are degraded and limiting crop production. Improved management can increase crop yields and soil health, but trade-offs in the use of resources, such as organic amendments, need to be considered. We sampled 427 fields across agri-systems in the southwest o...

Transcranial Direct Stimulation, Mirror Therapy, and Virtual Reality Interventions for Upper Limb Motor Recovery After Stroke: A Systematic Review and Meta-Analysis with Implications for Low-Resource Settings

Abstract Background: Stroke rehabilitation remains a major global challenge, especially in low-resource settings where access to specialized rehabilitation centers is limited. Structured, feasible, and evidence-based neuroplasticity intervention service delivery is not widely use...

Predicting ecosystem services values using land use land cover and climate change scenarios in Maze National Park and its surroundings, Ethiopia

Land-use and land-cover and climate change are significant environmental factors affecting ecosystems and the services they provide. Their impacts are evident, and continued changes are expected to significantly affect future ecosystem services. Therefore, this study predicts the...

Rare case of Rasmussen’s encephalitis in Ethiopia: a case report

Rasmussen’s encephalitis (RE) is an uncommon chronic neurological condition that presents with gradual neurological and cognitive impairment caused by a unilateral inflammation of the cerebral cortex. The case highlights the occurrence of Rasmussen’s encephalitis in a setting wit...

Portable Low-Field MRI of the Brain in Clinic and Community Settings

This cohort study evaluates portable, low-field magnetic resonance imaging (MRI) against conventional MRI in memory clinic and community cohorts.

Maternal knowledge of risk factors and preventive measures of congenital birth defects in public health institution of Hawassa City, Southern Ethiopia

Congenital birth defects are structural or functional abnormalities present at birth that affect approximately one in thirty three infants globally, with over 90% of cases occurring in low- and middle-income countries. Maternal knowledge of risk factors and preventive measures is...

Molecular evidence of pfhrp2/pfhrp3 exon 2 deletions and potential HRP2-based RDT diagnostic failure in southern Ethiopia

Deletions of pfhrp2 and pfhrp3 in Plasmodium falciparum compromise the diagnostic performance of HRP2-based rapid diagnostic tests. These deletions can cause false-negative HRP2-based RDT results, leading to missed treatment and ongoing transmission. This study determined the pre...

Implementation and challenges of teacher development programs in secondary schools of Sidama national regional state

Effective teacher professional growth is essential for instructional quality in transitioning administrative contexts. This study assesses the implementation of Teacher Development Programs (TDP) in secondary schools of the Sidama National Regional State, Ethiopia. Adopting an ex...

Radiosensitivity and early-stage morpho-physiological profiling of M1V1 sweet potato (Ipomoea batatas L.) vine cuttings to different doses of gamma irradiation: breeding for mutants with virus resistance, nutritional quality, and high yield

Abstract Background Induced mutation using physical mutagens like gamma irradiation is an efficient strategy for broadening genetic diversity in vegetatively propagated polyploid crops like sweet potato ( Ipomoea batatas L. ) , where conventional breeding is constrained by high h...

Immunohistochemical profiling of the tumor microenvironment in Ethiopian breast cancer tissue: insights into pathology and subtypes

Breast cancer (BC) is the most common malignancy globally and poses a significant public health challenge in sub-Saharan Africa (SSA). To date, the clinical use of immunotherapies has improved patients’ outcomes in high-income countries, but is not feasible in most countries in S...

The effect of drought on physiological and agronomic traits of tef [Eragrostis tef (Zucc.) Trotter]

Increased intensity and duration of drought as a consequence of global warming is resulting in increased crop failure and food insecurity. This is particularly prevalent in regions where agriculture is rain fed, as the resultant water deficit in crop tissues as a consequence of i...

Trends, causes, and delays associated with maternal mortality in public hospitals of Hawassa City, Southern Ethiopia: a five-year retrospective study
