Una discusión sobre la curva de Phillips de Friedman y la tasa natural de desempleo

open access: yesLecturas de Economía, 2007
En este escrito se evalúa la consistencia teórica de la Curva de Phillips de Milton Friedman. Para esto se retoma la exposición de Friedman, destacando sus aportes al análisis de corto plazo del desempleo, los salarios y los precios, frente a la teoría ...

The K1.8BR spectrometer system at J-PARC

open access: yes, 2012
A new spectrometer system was designed and constructed at the secondary beam line K1.8BR in the hadron hall of J-PARC to investigate $\bar K N$ interactions and $\bar K$-nuclear bound systems.

Prerequisites for a computational approach to Minoan chronology

open access: yesArchaeometry, Volume 67, Issue S1, Page 110-130, June 2025.
Abstract The paper examines the development, adoption, and limitations of the relative chronology system for Minoan pottery, initially established by Sir Arthur Evans and Duncan Mackenzie during the excavation of Knossos (1900–1906). Despite its weaknesses, this system remained largely unchanged due to its convenience rather than its accuracy.

Advancement in Color Image Processing using Geometric Algebra

open access: yes, 2008
This paper describes an advancement in color image processing, using geometric algebra. This is achieved using a compact representation of vectors within $n$ dimensional space. Geometric Algebra (GA) is a preferred framework for signal representation and

A Model of Secular Stagnation: Theory and Quantitative Evaluation

open access: yesAmerican Economic Journal: Macroeconomics, 2017
This paper formalizes and quantifies the secular stagnation hypothesis, defined as a persistently low or negative natural rate of interest leading to a chronically binding zero lower bound (ZLB).

Joint Wire Cutting with Non‐Maximally Entangled States

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 5, May 2025.
Wire cutting decomposes large quantum circuits into smaller subcircuits by severing connecting wires, enabling execution on multiple distributed devices. This study employs non‐maximally entangled (NME) states in joint wire cuts to reduce their overhead.

Fine group gradings of the real forms of $sl(4,\C)$, $sp(4,\C)$, and $o(4,\C)$

open access: yes, 2007
We present an explicit description of the 'fine group gradings' (i.e. group gradings which cannot be further refined) of the real forms of the semisimple Lie algebras $sl(4,\C)$, $sp(4,\C)$, and $o(4,\C)$. All together 12 real Lie algebras are considered,

The First Near‐Real‐Time Compatible Numerical Method for Co‐Seismic Ionospheric Disturbances Simulation

open access: yesGeophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Numerous studies demonstrated a huge potential for ionospheric total electron content (TEC) measurements to be included in earthquake and tsunami risk assessments. However, up to now, only a few methodologies or tools can be used in near‐real‐time (NRT) for these purposes.
