”Touch” in D.H.Lawrence [PDF]

open access: yes, 2011
Lawrence thinks that touching is to live in the deepest of life as part of the universe; for us to live really or wholly as humans is to enjoy what we are given intrinsically. There are many ways of touching in human life.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

open access: yesAdvanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

B Cells are Activated via a Nanoporous Interface that Stabilizes Microvilli and Engages Mechanosensitive Ion Channels

open access: yesAdvanced Science, EarlyView.
B cells can be activated independently of antigen recognition via mechanical stimulation through nanoporous substrates. Exposure to such substrates induced B cell microvilli extension into the pores, intracellular Ca2+ signaling, phosphorylation of signaling proteins, and CD69 expression.

EndoTac: An Endoscopic Camera‐Based Tactile Sensor with High Sensitivity for Minimally Invasive Surgery

open access: yesAdvanced Science, EarlyView.
EndoTac presents a trocar‐compatible endoscopic vision‐based tactile sensor that uses a convex mirror to enlarge side‐facing tactile coverage during minimally invasive vessel palpation. Distorted tactile images are unwarped and processed by a learning model to estimate vascular deformation, enabling sensitive, spatially distributed tactile perception ...

The relation between longing for touch and the implicit evaluation of images of touch

open access: yesActa Psychologica
Longing for touch (LFT) refers to the discrepancy between the amount of touch that is desired and received. Previous studies have suggested that LFT might influence the perception of touch, but the results are conflicting.

An Innervated Human Skin Equivalent that Electrically Encodes Mechanical and Thermal Stimuli

open access: yesAdvanced Science, EarlyView.
An innervated human skin equivalent is integrated with high‐density microelectrode arrays to reveal how engineered free nerve ending–like structures translate touch and temperature into electrical codes. Mechanical indentation and thermal stimulation engage the engineered somatosensory circuitry and evoke distinct firing and waveform signatures ...

A Bioinspired, Multimodal Soft Tactile Skin with Task‐Adaptive Perception for Intelligent Robotic Manipulation

open access: yesAdvanced Science, EarlyView.
Perception in robotic manipulation improves through the cooperative and complementary operation of biologically inspired multimodal tactile sensors. Receptor‐specific contribution analysis identifies which sensing modalities are required for specific tactile tasks.

Cavity‐Enhanced Eye‐Readable Detection of 0.1% H2 via Active Modulation of Charge‐Transfer Plasmons

open access: yesAdvanced Science, EarlyView.
A cavity‐structured nanoparticle sensor is developed for highly sensitive, eye‐readable hydrogen detection. Its excellent colorimetric response arises from a hydrogen‐induced charge‐transfer mechanism: reduction of the dielectric oxide shell in H2 triggers a transition from the plasmonic gap mode to the charge‐transfer plasmon mode.
