Article Abstract
Cross-validating new methods for recording neural activity is necessary to accurately interpret and compare the signals they measure. Here we describe a procedure for precisely aligning two probes for in vivo "paired-recordings" such that the spiking activity of a single neuron is monitored with both a dense extracellular silicon polytrode and a juxtacellular micropipette. Our new method allows for efficient, reliable, and automated guidance of both probes to the same neural structure with micrometer resolution. We also describe a new dataset of paired-recordings, which is available online. We propose that our novel targeting system, and ever expanding cross-validation dataset, will be vital to the development of new algorithms for automatically detecting/sorting single-units, characterizing new electrode materials/designs, and resolving nagging questions regarding the origin and nature of extracellular neural signals.

To address the growing demand for temperature control precision and uniformity in wafer processing, a specialized electrostatic chuck temperature control system based on thermal control coatings is proposed, aiming to enhance thermal management robustness and homogeneity. This study employs a zoned control methodology using metal-oxide conductive coatings on silicon carbide wafer heating plates. A quadrant-based thermal control coating model was established, and finite element analysis was conducted to compare temperature distribution characteristics across three geometric configurations: sectorial, spiral, and zoned designs.

Enzymatic deoxyribonucleic acid (DNA) synthesis (EDS) is an environmentally friendly approach capable of generating longer and more complex sequences than chemical synthesis, making it a promising next-generation technology for high-throughput single-stranded DNA production. However, precise sequence control at high throughput remains a key challenge. Here, we present a novel electronically controlled deprotection chemistry (ECDC) integrated with a hydrogel-primer modification system on-chip for efficient multiplexed EDS.

Background: As advanced treatment plans increasingly include optimizing both dose and linear energy transfer (LET), there is a growing demand for tools to measure LET in clinical settings. Although various detection systems have been investigated in this pursuit, the scarcity of detectors capable of providing per-ion data for a fast and streamlined verification of LET distributions remains an issue. Silicon pixel detector technology bridges this gap by enabling rapid tracking of single-ion energy deposition.

Background: Photon-counting computed tomography (CT) bears promise to substantially improve spectral and spatial resolution. One reason for the relatively slow evolution of photon-counting detectors in CT-the technology has been used in nuclear medicine and planar radiology for decades-is pulse pileup, that is, the random staggering of pulses, resulting in count loss and spectral distortion, which in turn cause image bias and reduced contrast-to-noise ratio (CNR). The deterministic effects of pileup can be mitigated with a pileup-correction algorithm, but the loss of CNR cannot be recovered, and must be minimized by hardware design.

The precise and selective determination of ginsenosides, pharmacologically diverse saponins abundant in Panax species, is crucial for their therapeutic development and stringent quality control. However, inherent challenges, including their weak ultraviolet absorption and the high polarity imparted by sugar moieties, complicate their determination. Addressing these limitations, this study introduces the first-time construction and application of a boronate affinity dendritic mesoporous silica nanomaterial (BA-DMSN) as a highly efficient adsorbent for ginsenoside pretreatment.
