Quantum Biology: Can we explain olfaction using quantum phenomenon? [PDF]
arXiv, 2019 The sense of smell is an important part of living organisms. It assists with the interaction of the living organism with its environment. The mechanism by which smell is detected and identified is not fully known. Earlier, shape theory was proposed as an explanation for odor perception mechanism.

Propriety of various examinations for subjective symptoms of olfactory disorders. [PDF]
Eur Arch OtorhinolaryngolPurpose In Japan, two types of tests for diagnosing olfactory disorders, T and T (T&T) olfactometry and intravenous olfactory tests, are covered by insurance and performed on patients with olfactory disorders.

The mysterious sense of smell: evolution, historical perspectives, and neurological disorders
Frontiers in Human NeurosciencePhylogenetically, the chemical sense of smell is the oldest of all sensory modalities in terrestrial and aquatic organisms. For most non-human species in the wild, it is essential like other senses for survival because it aids nutrition, detection of ...

Deficiency of Aging‐Related Gene Chitinase‐Like 4 Impairs Olfactory Epithelium Homeostasis
Cell Proliferation, EarlyView.Deficiency of Chil4 impairs OE homeostasis through loss of sustentacular cells and a specific type of immature sensory neuron, cell cycle arrest in globose basal cells, and inflammatory activation in microglia‐like cells. ABSTRACT Mammalian olfactory epithelium (OE) undergoes consistent self‐renewal throughout life.

Machine olfaction using time scattering of sensor multiresolution graphs [PDF]
arXiv, 2016 In this paper we construct a learning architecture for high dimensional time series sampled by sensor arrangements. Using a redundant wavelet decomposition on a graph constructed over the sensor locations, our algorithm is able to construct discriminative features that exploit the mutual information between the sensors.

A Differential Topological Model for Olfactory Learning and Representation [PDF]
arXiv, 2020 This thesis is designed to be a self-contained exposition of the neurobiological and mathematical aspects of sensory perception, memory, and learning with a bias towards olfaction. The final chapters introduce a new approach to modeling focusing more on the geometry of the system as opposed to element wise dynamics.

The FEBS Journal, EarlyView.Heterotrimeric (αβγ) G proteins are usually inactivated by regulators of G protein signaling (RGS) proteins, but Gαs is an exception. Comparative structural analysis identified unique Gαs structural elements that may interfere with RGS binding. Mutagenesis and biochemical assays showed that three residues in the Gαs GTPase domain are both necessary and

Procrustean Orthogonal Sparse Hashing [PDF]
arXiv, 2020 Hashing is one of the most popular methods for similarity search because of its speed and efficiency. Dense binary hashing is prevalent in the literature. Recently, insect olfaction was shown to be structurally and functionally analogous to sparse hashing [6].
