The Solution of the “Cold Start Problem” in e-Learning
Procedia - Social and Behavioral Sciences, 2014 AbstractProblem Statement. Among the main problems of e-Learning one is t he “cold st art problem”. A learning environment cannot provide informat ion on a relevant difficulty of t he cont ent due t o t he lack of informat ion about a learner. The unsolved problem ent ails a reduct ion in t he effect iveness of t he learning process as overly difficult

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits
Advanced Science, EarlyView.This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Advanced Science, EarlyView.BNC2 exhibits context‐dependent opposing functions across multiple cancer types. This study reveals BNC2 as an oncogenic driver of melanoma proliferation and metastasis through transcriptional activation of PIK3CA. The natural compound TSN simultaneously degrades BNC2 and its oncogenic partner SMAD3 via CRBN‐dependent ubiquitination.
