Kernel Function-Based Ambiguity Function and Its Application on DOA Estimation in Impulsive Noise

Sensors, 2022
To solve the problem that the traditional ambiguity function cannot well reflect the time-frequency distribution characteristics of linear frequency modulated (LFM) signals due to the presence of impulsive noise, two robust ambiguity functions ...

Standardized Elemental Composition Analysis of Graphene‐Related 2D Materials (GR2M) With SEM/EDS and XPS Works Reliably

Small, EarlyView.
The elemental composition of a series of laboratory graphene oxide and reduced graphene oxide materials and a commercial graphene oxide material of high quality is analyzed with the standardless SEM/EDS quantification. XPS is used as a reference method.

Se remémorer la guerre dans trois pièces de Wajdi Mouawad [PDF]

Revue Roumaine d’Etudes Francophones
This article examines the representation of war and memory in Wajdi Mouawad’s theatre through Seuls (2008), Sœurs (2015), and Mère (2022). War is not portrayed merely as a historical event but as a psychic and social experience that deeply shapes

Long‐Term Outcomes After Slowly Resorbable P4HB Mesh Implantation: A Multicenter Analysis From European Registry

World Journal of Surgery, EarlyView.
Fully resorbable biosynthetic mesh composed of poly‐4‐hydroxybutyrate (P4HB), have been designed for incisional hernia (IH) repair, including in contaminated surgical fields. While existing studies have demonstrated its safety and efficacy in the short term, comprehensive long‐term data, particularly after complete mesh resorption, remain scarce ...

Beamspace Unitary ESPRIT Algorithm for Angle Estimation in Bistatic MIMO Radar

International Journal of Antennas and Propagation, 2015
The beamspace unitary ESPRIT (B-UESPRIT) algorithm for estimating the joint direction of arrival (DOA) and the direction of departure (DOD) in bistatic multiple-input multiple-output (MIMO) radar is proposed. The conjugate centrosymmetrized DFT matrix is

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, EarlyView.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

Boredom, despondency, and the scourge that lays waste at noon: an anthropology of acedia Ennui, abattement et le fléau qui frappe à midi : une anthropologie de l'acédie

Journal of the Royal Anthropological Institute, EarlyView.
Attentive to the ways that inertia can take hold of life, Catholic monks recognize despondency as a potential not only within the monastery, but in contemporary society more widely. Such experiences are regularly mapped onto an understanding of what early Christian monks termed ‘acedia’ (a Greek term that can be translated as ‘lack of care’). Taking as
