Institutional Diversity in Banking and Economic Complexity

International Journal of Finance &Economics, EarlyView.
ABSTRACT In this paper, we test whether institutional diversity in banking systems is beneficial to economic complexity, using data for Italian provinces in the period 1998–2017. We compute different indexes that consider diversity from an ownership, institutional, business model and competition point of view and find that higher diversity has a ...

The mental health impacts of climate change across diverse global settings

Journal of Traumatic Stress, EarlyView.
Abstract Climate change represents a growing threat to global mental health, generating traumatic stress exposures directly through climate‐related disasters and indirectly through social networks and pervasive media coverage. This paper provides an overview of the symposium “The Mental Health Effects of Climate Change Across Diverse Global Settings ...

Outage Analysis of Correlated Source Transmission in Block Rayleigh Fading Channels [PDF]

, 2012
A goal of this paper is to theoretically derive the outage probability of the correlated source transmission in block Rayleigh fading channels. The correlation between the two information sources is assumed to be expressed by the bit flipping model ...

Reverse Link Outage Probabilities of Multicarrier CDMA Systems with Beamforming in the Presence of Carrier Frequency Offset

EURASIP Journal on Wireless Communications and Networking, 2008
The outage probability of reverse link multicarrier (MC) code-division multiple access (CDMA) systems with beamforming in the presence of carrier frequency offset (CFO) is studied. A conventional uniform linear array (ULA) beamformer is utilized.

Hybrid Cache Placement for Physical-Layer Security in Cooperative Networks

IEEE Access, 2018
Due to the broadcast nature of wireless transmission, traditional wireless two-hop relaying is vulnerable for eavesdroppers to overhear messages. In order to enhance the physical-layer security, this paper studies one cooperative network with caching ...

Outage probability of a cooperative maximum ratio transmission

2014 22nd Signal Processing and Communications Applications Conference (SIU), 2014
In this paper, we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve full diversity when used at tranmitters having multiple antennas while requiring no complexity increase at the receiver, the ...

Stabilising Routines in Complex Emergencies: How Basic Service Continuity Shapes Perceived Security

Public Administration and Development, EarlyView.
ABSTRACT This study examines how locally embedded actors describe the relationship between basic service continuity and perceived security in complex emergencies, with particular attention to the stabilisation of everyday routines. Using Proximity‐Predictability‐Attributability (PPA) as an analytic lens, we trace how interviewees relate access to water,

Development and Evaluation of a Low‐Cost, Semi‐Automated Camera Trap for Surveying Bumble Bee Communities

Remote Sensing in Ecology and Conservation, EarlyView.
Camera traps are emerging as a useful tool for noninvasive insect monitoring; however, it remains unclear how to lure diurnal insects to traps, how to detect them upon arrival, and how camera‐based methods compare to conventional sampling. We developed a low‐cost, open‐source camera trap to monitor wild bumble bees in agricultural fields. We found that

Outage Minimization of Energy Harvesting-Based Relay-Assisted Random Underlay Cognitive Radio Networks With Interference Cancellation

IEEE Access, 2021
This paper incorporates interference cancellation in the outage analysis of a wireless energy harvesting cognitive relay network. Based on an interference threshold, primary receivers are assumed to be able to cancel a fraction of the strongest ...

Three‐Year Propagation Experiment at Ku‐, Ka‐, and Q‐Band in French West Indies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT From January 2021 to December 2023, the Office National d'Etudes et de Recherches Aérospatiales (ONERA) and the Centre National d'Etudes Spatiales (CNES) conducted a three‐year Earth‐space propagation measurement campaign in Guadeloupe. The experiment used beacon receivers deployed in Pointe‐à‐Pitre airport to record signals at 11.2, 19.7, and
