Dielectrophoresis (DEP) is an effective method to manipulate cells. Printed circuit boards (PCB) can provide inexpensive, reusable and effective electrodes for contact-free cell manipulation within microfluidic devices. By combining PDMS-based microfluidic channels with coverslips on PCBs, we demonstrate bead and cell manipulation and separation within multichannel microfluidic devices.

We demonstrate the transmission of multiple independent signals through a multimode fiber using wavefront shaping employing a single spatial light modulator. By modulating the wavefront for each signal individually, spatially separated foci are transmitted. Potential applications are multiplexed data transfer in communications engineering and endoscopic light delivery in biophotonics.

Ion Channels

The movement of ions like sodium, potassium, and calcium into and out of the cell is essential to maintain the electrochemical gradient in living cells. The ion channels—a class of membrane transport proteins—help maintain this ionic gradient for the smooth functioning of physiological activities such as maintaining cell size and volume, conducting nerve impulses, and gas and nutrient exchange. Ion channels are specialized integral membrane proteins on the plasma membrane that allow specific...

We designed a dry-type 16 channel EEG sensor which is non-invasive, deformable, and re-usable. This paper describes the whole process from manufacturing the proposed EEG electrode to signal processing of visual evoked potential (VEP) signals measured on a mouse scalp using a dry non-invasive multi-channel EEG sensor.

Source: Laboratories of Gary Lewandowski, Dave Strohmetz, and Natalie Ciarocco—Monmouth University A multi-group design is an experimental design that has 3 or more conditions/groups of the same independent variable. This video demonstrates a multi-group experiment that examines how different interethnic ideologies (multiculturalism and color-blind) influence feelings about diversity and actions toward and out-group member. In providing an overview of how a researcher conducts a multi-group...
FAQs
These methods distinguish simultaneous signals using different organizing dimensions. Frequency-division assigns signals separate frequency ranges, while time-division separates them into different time intervals. Wavelength-division applies the same principle to optical wavelengths, and code-division uses distinct coding patterns. The choice determines how channels are allocated and recovered while supporting efficient use of a shared communication medium.
Channel allocation establishes where each independent signal belongs within the shared medium, allowing the receiver to identify the intended channel. Synchronization keeps the transmitter and receiver aligned, particularly when signals are separated by time or coding. If allocation or timing becomes inaccurate, signal recovery becomes less reliable and interference or crosstalk can increase.
The separation method, channel allocation, synchronization, and the quality of signal recovery all influence noise performance. Closely managed channels help limit crosstalk, which occurs when energy from one signal affects another. Engineers therefore evaluate how effectively the system separates signals and maintains reliable recovery, because these factors affect overall communication quality and infrastructure performance.
A typical workflow begins by assigning independent signals to distinct channels using frequency, time, wavelength, or code. The channels are then combined for transport through the shared medium. At the receiving end, the system separates the channels and recovers the signals, while engineers assess synchronization, crosstalk, interference, and noise performance throughout the process.
The approach supports several forms of communication infrastructure, including fiber-optic networks, wireless communication, satellite links, and data systems. In each setting, sharing a medium allows multiple signals to be carried without requiring a separate physical link for every one. This makes the technique relevant when engineers need greater capacity, improved bandwidth efficiency, reliability, or scalable network design.
By carrying multiple independent signals through shared resources, the technique increases capacity and improves bandwidth efficiency without multiplying physical links. Its value depends on effective channel separation, synchronization, and control of interference and crosstalk. These design considerations help engineers build communication systems that can support high throughput while preserving reliable signal recovery and allowing infrastructure to scale.
