Intelligent Selection of Machining Parameters in Multipass Turnings Using Firefly Algorithm

Modelling and Simulation in Engineering, 2014
Determination of optimal cutting parameters is one of the most important elements in any process planning of metal parts. In this paper, a new optimization technique, firefly algorithm, is used for determining the machining parameters in a multipass ...

Multipass Faraday rotators and isolators

Optics Express
Faraday isolators are usually limited to Faraday materials with strong Verdet constants. We present a method to reach the 45° polarization rotation angle needed for optical isolators with materials exhibiting a weak Faraday effect. The Faraday effect is enhanced by passing the incident radiation multiple times through the Faraday medium while the ...

Geochemical Modeling of Black Smoker Fluid Formation at the TAG Hydrothermal Vent Field

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Seafloor hydrothermal systems facilitate energy transport and chemical exchange between oceanic crust and seawater. The chemistry of hydrothermal fluids is attained through reactions with basaltic rock during fluid recharge, but the spatio‐temporal scales of fluid‐rock‐interaction at depth are difficult to constrain.

A Genetically Encoded Marker for Imaging of Internal Plasmodium Membranes

Molecular Microbiology, Volume 126, Issue 4, Page 462-472, October 2026.
IMMP is a peptide‐based marker that labels internal membranes across multiple stages and species of the malaria‐causing parasite Plasmodium. It works in both live and fixed samples and supports long‐term live‐cell imaging. ABSTRACT Fluorescence microscopy is a powerful tool to analyze the subcellular architecture, and long‐term live‐cell imaging ...

Output feedback control of linear multipass processes [PDF]

, 2001
An error actuated output feedback controller for a sub-class of linear multipass processes designated as 'differential unit memory' is defined. Further, the design of this controller for closed-loop stability is considered.

Cryogen‐Aided Chromatographic Purification of Millimole Quantities of Methane for Spectroscopic Clumped Isotope Analysis

Rapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Quantum cascade laser absorption spectroscopy (QCLAS) is a fast and reliable method for analyzing the bulk (𝛿13C‐CH4, 𝛿D‐CH4) and clumped isotopic (∆13CH3D and ∆12CH2D2) composition of methane. However, precise measurements of ∆12CH2D2 require 0.5 to 1.8 mmol of purified methane (equivalent to 15 to 40 mL at STP).

Multipass Channel Estimation and Joint Multiuser Detection and Equalization for MIMO Long-Code DS/CDMA Systems

EURASIP Journal on Wireless Communications and Networking, 2006
The problem of joint channel estimation, equalization, and multiuser detection for a multiantenna DS/CDMA system operating over a frequency-selective fading channel and adopting long aperiodic spreading codes is considered in this paper.

Laser‐Induced Oxidation of Silicon Using a 355 nm UV Laser and Its Molecular Dynamics Simulation

physica status solidi (a), Volume 223, Issue 17, 9 September 2026.
Laser‐induced silicon oxidation under 355 nm UV irradiation is investigated through combined experiments and molecular dynamics simulations. Temperature‐dependent oxidation mechanisms reveal a transition from surface‐limited oxidation to lateral oxygen diffusion and depth‐wise oxygen penetration, governing oxygen transport and oxide growth.
