Reversed Nested Miller-Based Four Stage CMOS Amplifier Frequency Compensation Approach

Active and Passive Electronic Components
This work presents a novel frequency compensation method for four-stage CMOS amplifiers, addressing the complexity and instability challenges prevalent in modern low-voltage, low-power electronic systems. The proposed approach employs nested differential

Torque behavior of one-phase permanent magnet AC motor [PDF]

, 2006
This paper presents a detailed comparative study of two starting and running methods for a single-phase permanent magnet synchronous motor, equipped with a squirrel-cage rotor. The analysis of the motor performance is realized for a pulse width modulated

An ultra‐processed food‐based cafeteria diet induces obesity, metabolic dysfunction, and tissue‐specific gene dysregulation in C57BL/6 mice

Animal Models and Experimental Medicine, EarlyView.
This schematic figure illustrates the experimental design and key findings of the study. Forty male C57BL/6 mice were assigned to either a standard diet control group or a cafeteria diet (CAFD) group for 16 weeks. CAFD induces obesity, insulin resistance (HOMA‐IR), hepatic steatosis, and dysregulation of a number of genes in visceral and subcutaneous ...

Analysis and design of a two-speed single-phase induction motor with 2 and 18 pole special windings [PDF]

, 2005
The motor presented employs multiple independent windings for operation with two very different pole numbers. The 18-pole field is produced with a symmetrical three-phase winding connected in a Steinmetz arrangement to a single-phase supply.

Quantifying Optical Disorder in CsFaPb(Br,I)3 Perovskites via Urbach Energy Analysis Using OPAL2 Fresnel‐Based Simulations

Advanced Physics Research, EarlyView.
ABSTRACT This study examines light‐matter interactions in CsFAPb(Br, I)3 perovskite thin films by analyzing their absorption, reflection, and emission properties using Fresnel‐based OPAL2 simulations. The optical spectra show sharp absorption edges at 1.55 – 1.60 eV for CH3NH3PbI3 and triple‐cation perovskites, which blue‐shift to ∼1.8 eV with ...

Ontogenetic changes and sexual dimorphism in the cranium and mandible of the Atlantic walrus (Odobenus rosmarus rosmarus L.)

The Anatomical Record, EarlyView.
Abstract Walruses have been an important subsistence and cultural resource for humans and have been exploited for millennia across their distribution. This exploitation has contributed to severe declines in several populations and local extirpations.
