Ship detection in complex environment is a challenging task due to strong background inferences, for which various deep-learning-based methods have been proposed. However, they poor performance on detecting nearshore ships medium-resolution synthetic aperture radar (SAR) images the loss of typical features and confusion with land scatterers. The availability multitemporal SAR gives opportunity ...

LPS stimulates monocytes/macrophages through TLR4, resulting in the activation of a series of signaling events that potentiate the production of inflammatory mediators. Recent reports indicated that the inflammatory response to LPS is diminished by PI3K, through the activation of the serine/threonine kinase Akt. SHIP is an inositol phosphatase that can reverse the activation events initiated by...

SHIP-2 is a phosphoinositidylinositol 3,4,5 trisphosphate (PtdIns[3,4,5]P3) 5-phosphatase that contains an NH2-terminal SH2 domain, a central 5-phosphatase domain, and a COOH-terminal proline-rich domain. SHIP-2 negatively regulates insulin signaling. In unstimulated cells, SHIP-2 localized in a perinuclear cytosolic distribution and at the leading edge of the cell. Endogenous and recombinant S...

The Src homology 2 domain-containing inositol 5'-phosphatase (SHIP) is recruited to immunoreceptor tyrosine-based inhibition motif (ITIM)-containing proteins, thereby suppressing phosphatidylinositol 3-kinase (PI 3-kinase)-dependent pathways. The role of SHIP in phagocytosis, a PI 3-kinase-dependent pathway, is unknown. Overexpression of SHIP in macrophages led to an inhibition of phagocytosis ...

SH2-containing Inositol Phosphatase (SHIP) is a 145 kD protein expressed in hematopoietic cells. SHIP is phosphorylated on tyrosine after receptor binding by several cytokines and has a negative role in hematopoiesis. We cloned a murine complementary DNA (cDNA) sequence for an isoform of SHIP with an internal 183 nucleotide deletion, encoding a protein 61 amino acids shorter than 145 kD SHIP. T...

Various port cities and authorities have established emission control areas (ECAs) to constrain ships’ fuel usage in a specified offshore geographical range. However, these ECA policies involve high costs low monitoring regulation enforcement efficiencies. In this study, meeting model was used investigate the drone-scheduling problem by considering simultaneous movements of drones ships. Set-co...

Synthetic aperture radar (SAR) image ship detection is currently a research hotspot in the field of national defense science and technology. However, SAR images contain large amount coherent speckle noise, which poses significant challenges task detection. To address this issue, we propose filter convolution, novel design that replaces traditional convolution layer suppresses noise while extrac...

SHIP and SHIP-2 are inositol phosphatases that regulate FcγR-mediated phagocytosis through catalytic as well as non-catalytic mechanisms. In this study we have used two-dimensional fluorescence difference gel electrophoresis (DIGE) analysis to identify downstream signaling proteins that uniquely associate with SHIP or SHIP-2 upon FcγR clustering in human monocytes. We identified LyGDI as a bind...
