The Adoption and Impact of Improved Maize and Land Management Technologies in Uganda [PDF]

In spite of the fact that the Ugandan National Agricultural Research System has developed and released several production-enhancing technologies over a century, yields of most major crops at the farm level have been low.

Empiricism without Magic: Transformational Abstraction in Deep Convolutional Neural Networks [PDF]

, 2018
In artificial intelligence, recent research has demonstrated the remarkable potential of Deep Convolutional Neural Networks (DCNNs), which seem to exceed state-of-the-art performance in new domains weekly, especially on the sorts of very difficult ...

ReMoDe – Recursive modality detection in distributions of ordinal data

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract The detection of the number of modes in distributions of ordinal data is relevant for applied researchers across disciplines, from uncovering polarization to detecting incidence groups in clinical symptom scales. Yet, established modality detection methods are either purely descriptive or not developed for ordinal data.

Offspring Size Resolves a Population Growth Paradox in Rays and Skates

Fish and Fisheries, EarlyView.
ABSTRACT The maximum intrinsic population growth rate, rmax, is a key determinant of sustainable fishing limits and is increasingly used in risk assessments. We previously showed how the rmax of rays and skates (subclass Batoidea) scales with adult body size, temperature (and hence depth) such that smaller‐bodied species and those in warmer, shallower ...

Narcolepsy and rapid eye movement sleep

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Since the first description of narcolepsy at the end of the 19th Century, great progress has been made. The disease is nowadays distinguished as narcolepsy type 1 and type 2. In the 1960s, the discovery of rapid eye movement sleep at sleep onset led to improved understanding of core sleep‐related disease symptoms of the disease (excessive ...

Understanding marine biodiversity patterns and drivers: The fall of Icarus

Marine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Long‐term effects of clear‐cutting forestry on ectomycorrhizal fungi in boreal forest

New Phytologist, EarlyView.
Summary Clear‐cutting is detrimental to ectomycorrhizal fungi in a short time perspective, but long‐term effects on species richness and community composition are uncertain. To evaluate ecological sustainability of rotation forestry, we examined to what extent communities similar to those in old forests develop within the time frame of a rotation ...

Source‐to‐sink sediment transport reversals during glacial sea‐level lowstands sustain soil formation on pericoastal carbonate terrains

Sedimentology, EarlyView.
ABSTRACT Understanding the processes that drive soil formation is crucial for developing sustainable land‐use strategies, as changing land‐use practices and climate change exacerbate soil erosion. The formation of substantial arable soils on carbonate bedrock requires substantial dust accretion as the underlying bedrock lacks siliciclastic material. In

Eye Movements, Item Modality, and Multimodal Second Language Vocabulary Learning: Processing and Outcomes

Language Learning, Volume 76, Issue 2, Page 528-564, June 2026.
Abstract This study examined second language vocabulary processing and learning in reading only (RO) versus reading while listening (RWL). 119 English learners read or read‐while‐listening to a story embedded with 25 pseudowords, 10 times each, and had their eye movements tracked.

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

Ecography, Volume 2026, Issue 5, May 2026.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.
