Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP) for Engineering Glioma Tissues With Controlled Cellular and Extracellular Matrix Architectures

open access: yesSmall, EarlyView.
This study introduces an acoustics‐assisted tissue engineering approach, termed “Acoustic Tweezers‐Assisted Biomaterial Molding in Petri Dishes (TAMP),” which enables the fabrication of tissues with customizable extracellular matrix (ECM) geometries and various acoustically constructed internal cellular architectures, including parallel elongated ...

Fatigue Strength in Additive Toolmaking: A Study of Metal Binder Jetting and Electron Beam Melting for Processing Carbide‐Rich Cold‐Work Tool Steels

open access: yessteel research international, EarlyView.
Focusing on the critical tap hole region of the blast furnace, this work examines binder characteristics, prepares tap hole clay with different formulations, and evaluates their physical properties. The findings confirm the advantages of composite binders and offer a new binder option for tap hole clay.

A Study of the Transfer Function of Chopper Amplifiers

open access: yesA Study of the Transfer Function of Chopper Amplifiers
The chopper amplifier is frequently used in several types of d.c and a.c amplifiers as well as in d.c servomechanisms employing a.c control elements. In this paper the transfer function of the chopper amplifier is derived for a sinusoidal input signal.

Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

On the Maxumum Loop Gain of Chopper Amplifiers with a Make-before-break chopper

open access: yesOn the Maxumum Loop Gain of Chopper Amplifiers with a Make-before-break chopper
論文(Article) 著者の一人(中津山)によって発表されたチョッパ増幅器の精密な解析法を用いて,中央短絡形チョッパを用いたチョッパ増幅器の負帰還量の限((安定をそこなわずに帰還できる最大ループ利得)を計算し実測値と比較検討した。その結果両者は良く一致し,今までほっきりしなかった時定数が小さい場合の帰還量の限界が計算で求められ,この形のチョッパを用いた増幅器の安定性が明らかになった。これは,増幅器を設計する時の一つの基準になるであろう。  また,回路の時定数がチョッパ断続周期より大きい場合,誤差が少なく簡単に負帰還量の限界を求めることができる近似式が得られたので,これについても報告した。

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

open access: yesVIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...
