Dual-wavelength aerosol vertical profile measurements by MAX-DOAS at Tsukuba, Japan [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
We present vertical profiles of the aerosol extinction coefficient retrieved from ground-based Multi-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements at Tsukuba, Japan (36.1° N, 140.1° E), from November 2006 to ...

Tensor DoA Estimation With Directional Elements [PDF]

open access: yesIEEE Signal Processing Letters, 2017
Directivity gain patterns are treated as a physical diversity for tensor array processing, replacing space diversity, in addition to time and space shift diversities. We show that the tensor formulation allows to estimate directions of arrival under the assumption of unknown gain patterns, improving the performance of the omnidirectional case.

Obstructive sleep apnea and major depressive disorder: Shared transcriptional signatures and candidate pathways identified via bioinformatics analysis

open access: yesSleep Research, EarlyView.
Abstract Background Obstructive sleep apnea (OSA) frequently co‐occurs with major depressive disorder (MDD). However, the underlying biological mechanisms remain unclear. This study aimed to identify OSA‐related transcriptional signatures associated with depressive status using integrated bioinformatics and machine learning.

Investigating SME‐Inclusive Public‐Private AI Innovation Network: Evidence From U.S. Small Business Administration (1991–2023)

open access: yesThunderbird International Business Review, EarlyView.
ABSTRACT Understanding innovation policy is pivotal to enhancing national competitiveness for global value chain. This research investigates an SME‐Inclusive public‐private AI innovation network over time in the U.S. context (1991–2023), revealing how a government's demand‐based innovation policy bolsters technological prowess through isomorphism and ...

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

open access: yesVeterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.

Atom-Constrained Gridless DOA Refinement With Wirtinger Gradients

open access: yesIEEE Open Journal of Signal Processing
This paper proposes gridless sparse direction-of-arrival (DOA) refinement using gradient-based optimization. The objective function minimizes the fit between the sample covariance matrix (SCM) and a reconstructed covariance matrix.

Evaluation of MAX-DOAS aerosol retrievals by coincident observations using CRDS, lidar, and sky radiometer inTsukuba, Japan [PDF]

open access: yesAtmospheric Measurement Techniques, 2015
Coincident aerosol observations of multi-axis differential optical absorption spectroscopy (MAX-DOAS), cavity ring-down spectroscopy (CRDS), lidar, and sky radiometer were conducted in Tsukuba, Japan, on 5–18 October 2010. MAX-DOAS aerosol retrieval (for

Emergency Care Needs in an Asymmetric Conflict: A Facility‐Based Cohort Study From Israel on October 7, 2023

open access: yesWorld Journal of Surgery, EarlyView.
In an armed conflict with loss of territorial control and reduced EMS access, healthcare planners may need to anticipate significant prehospital death and that many patients arrive at hospital informally. ABSTRACT Background Due to the deteriorating global security situation, many countries are preparing their health systems for armed conflict. Wartime

DOA Estimation in the Uplink of Multicarrier CDMA Systems

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
We consider the uplink of a multicarrier code-division multiple-access (MC-CDMA) network and assume that the base station is endowed with a uniform linear array.
