Analysis of existing effectiveness and method to enhance the lightning, shielding and earthing protection schemes applied on the Parit Raja’s Telecommunication Tower System [PDF]

open access: yes, 2013
Lightning, one of nature’s most destructive forces, continues to wreck havoc on lives and property especially in today’s electronic environment. It has been shown by field experiences that telecommunication towers are one of the preferential points

Reduced Maintenance DNA Methylation Thresholds Enable Sensitive Reporter Assays for UHRF1 and DNMT1 Inhibition

open access: yesAdvanced Science, EarlyView.
The authors engineer colorectal cancer cells with reduced redundancy of UHRF1 and DNMT1, key DNA methylation maintenance factors, lowering the maintenance threshold and sensitizing cells to inhibition. They develop reporter assays driven by endogenous tumor‐suppressor gene promoters with enhanced sensitivity and dynamic range to demethylating drugs ...

Lightning characteristics based on data from the Austrian lightning locating system [PDF]

open access: yesIEEE Transactions on Electromagnetic Compatibility, 1998
We compare various lightning characteristics measured by the Austrian lightning locating system [Austrian Lightning Detection and Information System (ALDIS)] with those found in the literature. The latter are typically based on measurements of lightning electric fields.

Selective Targeting of Immune Checkpoints HLA‐G and CD47 Using Novel Dual Signaling Protein DSP216 Promotes Innate Anticancer Immunity

open access: yesAdvanced Science, EarlyView.
The inhibitory immune checkpoints HLA‐G and CD47 are expressed on certain tumor types and inhibit immune cells in the tumor microenvironment. DSP216 binds specifically to cancer cells expressing both HLA‐G and CD47, and blocks their inhibitory signaling.

Extreme Polaritonic Interactions in a Room‐Temperature Designable Sub‐Nanocavity Quantum Electrodynamic Platform

open access: yesAdvanced Science, EarlyView.
 A nanoparticle‐cluster‐on‐mirror (NPcoM) serves as a functionally deterministic sub‐nanocavity that emulates picocavities, enabling extreme light–matter interactions and polaritonic phenomena. ABSTRACT Pushing nanoscale optical confinement to its ultimate limits defines the regime of nano‐cavity quantum electrodynamics (nano‐cQED), where light‐matter ...

Lightning Occurrence between 2016 and 2020 in Fusagasugá, Cundinamarca, Colombia

open access: yesIngeniería
Context: Lightning is a powerful natural phenomenon that poses a risk to life and infrastructure, given the enormous amounts of energy it can transfer in short periods of time, especially in cloud-to-ground strikes.

Temporal Interference Stimulation Enhances Neural Regeneration

open access: yesAdvanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

Analysis of lightning localization errors based on different station layouts

open access: yes暴雨灾害
To explore the influence of the lightning detection station layout on lightning location accuracy, the magnetic field waveform observation data from the natural lightning observation test base at Jiuxian Mountain in Fujian Province were used and ten ...

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

open access: yesAdvanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.
