Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

Delivering courses modelled using IMS Learning Design [PDF]

open access: yes, 2003
E-learning promises efficiency of education. This promise is based on the economics of multiple delivery, whereby initial production costs for an e-learning course are recouped by delivering the course to different groups of learners at different times.

An Explainable and Lightweight CNN Framework for Robust Potato Leaf Disease Classification Using Grad‐CAM Visualization

open access: yesApplied AI Letters, Volume 7, Issue 1, February 2026.
Proposed model achieves 99.14% accuracy with near‐perfect precision, recall, and F1 across all classes; Grad‐CAM visualizations confirm focus on biologically relevant symptom‐associated regions. ABSTRACT For identifying foliar diseases in crops at an early stage, accurate detection is necessary in maintaining food security, minimizing economic losses ...

Shortcomings of learning design approaches and a possible way out [PDF]

open access: yes, 2008
Shifting away from traditional instructional design to younger research streams like personalized, workflow-based or collaborative e-learning, learning design (LD) has become an important issue in the field of technology-enhanced learning.

Using IMS Learning Design to Model Curricula [PDF]

open access: yes, 2006
The traditional notion of the curriculum as a fixed list of topics to be studied sequentially is under strain as pressure for flexibility in education increases. However, curriculum flexibility can lead to curriculum complexity, hindering learners in the development of their competences.

Proteomic Analysis of Regulated Dendritic Cell Endosomes Reveals Dynamic Adaptation to Antigen Uptake and Cross‐Presentation

open access: yesEuropean Journal of Immunology, Volume 56, Issue 2, February 2026.
Phagocytosis of yeast activates recruitment of proteases and trafficking factors from the secretory and endosomal pathways to the IRAP compartment and subsequently phagosomes, promoting cross‐presentation. In the absence of Sec22b, IRAP endosome and phagosome maturation to late endosomes is accelerated.

Seismic Structural Response and Loss Estimation for Dense Urban Districts Using Neural Network Parameterized Gaussian Process

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 2, Page 397-412, February 2026.
ABSTRACT Earthquakes pose a major threat to urban areas, causing fatalities, injuries, and significant economic losses. This study proposes a Gaussian process parametrized by deep neural networks (DNN–GP) as an efficient surrogate for assessing seismic losses of building structures at a regional scale.

An evaluation of pedagogically informed parameterised questions for self assessment

open access: yes, 2008
Self-assessment is a crucial component of learning. Learners can learn by asking themselves questions and attempting to answer them. However, creating effective questions is time-consuming because it may require considerable resources and the skill of ...
