Comprehensive Instrumental Odor Analysis Using SIFT-MS: A Case Study

, 2018
Instrumental analysis of odor is challenging due to the chemical diversity of many important odorants, the high sensitivity required to achieve human odor thresholds, and the dynamic nature of the odor itself.

Understanding Egg Price Volatility and Policy Implications in the U.S. With Machine Learning

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Eggs are an inexpensive and sustainable source of proteins, but volatility in the U.S. egg prices has intensified in recent years, raising concerns over food affordability and market stability. This study examines the drivers of U.S. egg price dynamics over 2004–2025 using a two‐stage framework that combines LASSO‐based variable selection with

Biomimetic 3D Tactile Sensor System With Neuromorphic Encoding for Fascicle‐Level Feedback

Advanced Intelligent Systems, EarlyView.
A 3D biomimetic tactile sensor system converts skin‐like mechanical interactions into neural stimulation‐ready spike patterns. Embedded slow‐ and fast‐adapting sensors distinguish sustained pressure from transient touch, while neuromorphic encoding preserves their temporal signatures.

Taxonomic reassessment of fossil Sequoia and Protosequoia from the Upper Miocene of Central Honshu, Japan, with implications for leaf morphological variation in extant S. sempervirens

American Journal of Botany, EarlyView.
Abstract Premise Since its emergence in the Mesozoic, Sequoia (Cupressaceae) has been considered to possess conserved leaf morphology. However, recent studies have shown that the leaves of extant S. sempervirens become smaller, with a scale form, with increasing tree height.

A Ruthenium‐(Ph‐BPE) Catalyst for Asymmetric Alkynylation of Fluoral: Enantioselection From 1 of 12 Fluxional Stereogenic‐at‐Ruthenium Complexes

Angewandte Chemie International Edition, EarlyView.
The first enantioselective alkynylations of aqueous fluoral are described. These processes are catalyzed by an iodide‐bound ruthenium‐(Ph‐BPE)‐catalyst; an octahedral metal complex that can exist as 12 diastereomeric‐at‐metal isomers. Calculations reveal that 2 of 12 stereoisomeric complexes account for 99.9% of the Boltzmann population and that ...
