Business-Cycle Anatomy [PDF]

open access: yesAmerican Economic Review, 2020
We propose a new strategy for dissecting the macroeconomic time series, provide a template for the business-cycle propagation mechanism that best describes the data, and use its properties to appraise models of both the parsimonious and the medium-scale variety.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Is There a European Business Cycle? [PDF]

open access: yesSSRN Electronic Journal, 2003
The paper uses quarterly GDP data for some 30 years up to and including 2001, to examine the identity and development of the European business cycle. Cycles are identified by using a band-pass filter version of the Hodrick-Prescott filter and affiliations are examined using clustering techniques and classical multidimensional scaling applied to cross ...

Business Cycle Narratives [PDF]

open access: yesSSRN Electronic Journal, 2018
Research about narratives’ role in economics is scarce, while real word experience and research in other sciences suggest they matter a lot. This article proposes a view and methodology for quantifying the epidemiology of media narratives relevant to business cycles in the US, Japan, and Europe.

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Electrically Readable Lateral Flow Assay Using Organic Transistors for Diagnostic Applications

open access: yesAdvanced Materials, EarlyView.
Electrolyte‐gated organic field‐effect transistors (EGOFETs) are integrated with lateral flow (LF) paper fluidics to create a reusable, portable, and low‐cost point‐of‐care (PoC) diagnostic test. The devices are validated for Human Immunoglobulin G detection, achieving high sensitivity (0.1 fm), selectivity, and reproducibility with rapid results in 20–

Co1/Ru Single‐Atom Alloy Catalyst for Sustainable Polypropylene Hydrogenolysis to Long‐Chain Liquid Products

open access: yesAdvanced Materials, EarlyView.
A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

EMPLOYMENT AND THE BUSINESS CYCLE [PDF]

open access: yesThe Manchester School, 2013
This paper investigates the differences in the cyclical dynamics in employment on non‐agricultural payroll (ENAP) and total civilian employment (TCE), and the implications for monitoring US business cycles in real time. We find that employment measures have diverged considerably around the last three recessions and subsequent recoveries.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Borders and business cycles [PDF]

open access: yesJournal of International Economics, 1999
We document that business cycles of U.S. Census regions are substantially more synchronized than those of European Union countries, both over the past four decades and the past two decades. Data from regions within the four largest European countries confirm the presence of a European border effect—within-country correlations are substantially larger ...
