The quantron is a hybrid neuron model related to perceptrons and spiking neurons. The activation of the quantron is determined by the maximum of a sum of input signals, which is difficult to use in classical learning algorithms. Thus, training the quantron to solve classification problems requires heuristic methods such as direct search. In this paper, we present an approximation of the quantron trainable by gradient search. We show this approximation improves the classification performance of direct search solutions. We also compare the quantron and the perceptron's performance in solving the IRIS classification problem.

Data classification is an important research direction in machine learning. In order to effectively handle extensive datasets, researchers have introduced diverse classification algorithms. Notably, Kernel Extreme Learning Machine (KELM), as a fast and effective classification method, has received widespread attention.

Diabetes mellitus (DM) and neuroendocrine tumors (NET) can exert unfavorable effects on each other prognosis. In this narrative review, we evaluated the effects of NET therapies on glycemic control and DM management and the effects of anti-diabetic therapies on NET outcome and management. For this purpose, we searched the PubMed, Science Direct, and Google Scholar databases for studies reporting the effects of NET therapy on DM as well as the effect of DM therapy on NET.

Background: Recent studies suggest genome-wide-association-studies (GWAS) loci confer their effects on microglia in late-onset Alzheimer's disease (LOAD) brains. Relatively fewer studies have investigated the effects of other genome-wide significant loci (p<5e) using human neurons.
Method: GWAS itself cannot directly identify causal variant-(effector)gene-pairs as GWAS only reports the sentinel variant at a given locus.

Background: The accumulation of misfolded tau proteins, an Alzheimer's disease (AD) hallmark, starts decades before the emergence of cognitive decline and clinical diagnosis. Autopsy studies support a predictable progression of tau pathology through large-scale systems. However, less is known about the specific progression patterns.

Background: Various explanations have been proposed for how hearing impairment might be associated with increased risk of dementia. Several theories have proposed direct links with Alzheimer's disease (AD) neuropathology, either due to shared aetiology (i.e.
