Underdetermined DOA Estimation Using Unfold Coprime Array From the Perspective of Sum-Difference Co-Array

IEEE Access, 2019
Direction-of-Arrival (DOA) estimation with sparse non-uniform linear arrays (SNLAs) has recently attracted a growing concern for the reason that more sources than the number of physical sensors can be resolved as compared with the conventional uniform ...

Super-Resolution DoA Estimation on a Co-Prime Array via Positive Atomic Norm Minimization

Energies, 2020
A super-resolution direction-of-arrival (DoA) estimation algorithm that employs a co-prime array and positive atomic norm minimization (ANM) is proposed.

An Unbiased CO Survey Toward the Northern Region of the Small Magellanic Cloud with the Atacama Compact Array. II. CO Cloud Catalog

The Astrophysical Journal, 2023
The nature of molecular clouds and their statistical behavior in subsolar metallicity environments are not fully explored yet. We analyzed data from an unbiased CO ( J = 2–1) survey at the spatial resolution of ∼2 pc in the northern region of the Small ...

Co-array Fortran Performance and Potential: An NPB Experimental Study [PDF]

, 2004
Co-array Fortran (CAF) is an emerging model for scalable, global address space parallel programming that consists of a small set of extensions to the Fortran 90 programming language. Compared to MPI, the widely-used message-passing programming model, CAF’s global address space programming model simplifies the development of single-program-multiple-data

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Underdetermined AOA Estimation Using Non-Uniform Sub-Connected Hybrid Beamforming Systems

IEEE Open Journal of the Communications Society
Hybrid beamforming (HBF) is emerging as a key technology for future wireless networks, particularly in millimeter wave (mmWave) bands. In this paper, we present a non-uniform sub-connected hybrid beamforming (NSC-HBF) system that enables the ...

Nested Array Sensor With Grating Lobe Suppression and Arbitrary Transmit–Receive Beampattern Synthesis

IEEE Access, 2018
Sparse arrays have potential advantages over their regularly spaced counterparts, but they will generate undesired grating lobes. This paper investigates a sparse linear phased-array for grating lobe suppression and arbitrary transmit-receive beampattern

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Co-array optimization of CMUT arrays for Forward-Looking IVUS

2009 IEEE International Ultrasonics Symposium, 2009
The ring annular array structure is a preferred configuration for implementing Forward-Looking IVUS (FL-IVUS) catheters as it allows for volumetric imaging as well as use of a guidewire at the center. CMUT technology is promising for these arrays especially with the flexibility of locating array elements on the circular donut area efficiently.
