Em direção ao ruído: loop de desaparecimentos ao rés do corpo

Palíndromo
Este artigo se dedica a uma análise do disco Isto (2019), obra de Cildo Meireles realizada com a voz da locutora Íris Lettieri. Assim como em Isto o artista recorreu ao loop para reunir, sonoramente e sutilmente, ambos os lados do disco, a escrita deste

Differential equations for multi-loop integrals and two-dimensional kinematics

, 2012
In this paper we consider multi-loop integrals appearing in MHV scattering amplitudes of planar N=4 SYM. Through particular differential operators which reduce the loop order by one, we present explicit equations for the two-loop eight-point finite ...

Diversity and complexity in neural organoids

FEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Medical Diagnosis Based on Multi-threshold Fuzzy Petri Net with Loop

Journal of Harbin University of Science and Technology
To settle the loop judgement issue of the medical diagnosis process, a multi-threshold fuzzy Petri net with loop (MTFPNL) is proposed to simulate the evidence-based medical diagnosis process of“ initial diagnosis-confirmation”.

AAA+ protein unfoldases—the Moirai of the proteome

FEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Pseudonoise code tracking loop [PDF]

, 1980
A delay-locked loop is presented for tracking a pseudonoise (PN) reference code in an incoming communication signal. The loop is less sensitive to gain imbalances, which can otherwise introduce timing errors in the PN reference code formed by the ...

Two-Loop Diagrammatics in a Self-Dual Background

, 2003
Diagrammatic rules are developed for simplifying two-loop QED diagrams with propagators in a constant self-dual background field. This diagrammatic analysis, using dimensional regularization, is used to explain how the fully renormalized two-loop Euler ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

A technique to eliminate false lock in PCM demodulation [PDF]

, 1973
One loop provides error signal which adjusts voltage controlled oscillator. Second loop multiplies input signal with generated in-phase signal. Both signals are integrated over bit period.
