Remark on multiplicative functions

In this note it is proved that if \(f\) is a multiplicative function and for some \(k\) we have \(f(k)\ne 0\), then \[ F_k(n) = f(kn)/f(k) \text{ is multiplicative}.\] For \(f = \varphi\) (Euler's totient) this result was obtained by \textit{D. H. Lehmer} and \textit{E. Lehmer} [Stud. Math. Anal. related Topics, Essays in Honor of G.

Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels

Advanced Healthcare Materials, EarlyView.
Thiol–norbornene click reactions are often used in the development of cell‐permissive 3D hydrogels. However, ene–ene crosslinks in other thiol–ene systems are known to limit permissivity. This study demonstrates the negative effects of norbornene homopolymerization on 3D cell spreading and circumvents the issue by modulating polymer degree of ...

Battery‐Free Dual‐Channel Wireless Neurostimulator Using Passive Circuitry for Neuropathic Pain Modulation

Advanced Healthcare Materials, EarlyView.
A compact, wireless neural stimulator featuring a novel tapping inductor enables selective and independent stimulation of the motor cortex in rats via a single receiver coil. This minimally invasive system effectively reduces neuropathic pain through targeted cortical activation, offering a new avenue for bioelectronic pain therapies and advancing ...

A Novel Microfluidic System for 3D Epidermis and Full‐Thickness Skin Growth for Nanoparticle Safety Assessment

Advanced Healthcare Materials, EarlyView.
This work presents a novel, dynamically perfused, configurable microfluidic system for epidermis‐only (E and full‐thickness skin (FT SoC) growth, emulating human skin structure and barrier function. Upon TiO2 nanoparticle exposure, the system reveals compromised barrier integrity, reduced metabolic activity, increased permeability, and chemokine‐driven

A Microphysiological Interface of Skeletal Myobundles and Inflamed Adipose Tissue for Recapitulating Muscle Dysfunction in an Obese Microenvironment

Advanced Healthcare Materials, EarlyView.
A human cell‐based microphysiological system integrates engineered muscle tissues with an inflamed adipose–macrophage niche to model obese microenvironment‐induced muscle dysfunction. Muscle contraction is quantified by pillar deflection coupled with computational stiffness estimation. Secretome and transcriptomic profiling reveal inflammation‐mediated
