Biophysical approaches for studying viral entry

FEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Energy harvesting from vibrations with a nonlinear oscillator [PDF]

, 2009
In this paper we present a nonlinear electromagnetic energy harvesting device that has a broadly resonant response. The nonlinearity is generated by a particular arrangement of magnets in conjunction with an iron-cored stator.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Frequency-Diverse Metasurface Antenna With Hybrid Bunching Methods for Coincidence Imaging

IEEE Access, 2020
A frequency-diverse metasurface antenna with hybrid bunching methods for coincidence imaging is proposed in this paper. The hybrid frequency-diverse bunching metasurface antenna contains an excitation system, a frequency-diverse metasurface and a double ...

An optical authentication system based on imaging of excitation-selected lanthanide luminescence

Science Advances, 2018
Random patterns of lanthanide(III) ion–doped zeolites were used to create a tamper-proof optical authentication system. Secure data encryption relies heavily on one-way functions, and copy protection relies on features that are difficult to reproduce. We

Cardiorespiratory system as system with limited excitation [PDF]

, 2019
A new modified cardiorespiratory model based on the famous DeBoer beat-to-beat model and Zaslavsky map (which describes dynamics of the respiratory system as a generator of central type) was studied in details.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Integrated charge excitation triboelectric nanogenerator

Nature Communications, 2019
Performance of triboelectric nanogenerators is limited by low and unstable charge density on tribo-layers. An external-charge pumping method was recently developed and presents a promising and efficient strategy towards high-output triboelectric ...

Multiple excitations in photosynthetic systems

Biophysical Journal, 1976
The yield of fluorescence in Chlorella from a 7 ns pulse of light is found to decrease gradually as a function of the number of hits in the photosynthetic units. The fivefold decrease in yield is spread over some three orders of magnitude of pulse energy and strongly suggests another random process in addition to that of photon absorption.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
