A Combined Antijamming and Antispoofing Algorithm for GPS Arrays

The Global Positioning System (GPS), with its accurate positioning and timing information, has become a commonly used navigation instrument for many applications. However, it is susceptible to intentional interference such as jamming and spoofing. The conventional antijamming GPS receiver fails to work in a combined jamming and spoofing attack scenario. To solve the problem, a...

SYNTHESIS, CRYSTAL STRUCTURES AND ANTIBACTERIAL ACTIVITIES OF BENZOHYDRAZONE DERIVATIVES FROM 4-DIETHYLAMINOSALICYLALDEHYDE

A series of three new benzohydrazone compounds, C18H21N3O3 (1), C19H23N3O3 (2), and C18H20ClN3O2 (3), derived from the condensation of 4-diethylaminosalicylaldehyde with 2-hydroxybenzohydrazide, 4-methoxybenzohydrazide, and 4-chlorobenzohydrazide, respectively, in methanol, were prepared. The compounds were characterized by elemental analysis, IR spectra, 1H NMR spectra, and...

Applications and potential of genome editing in crop improvement

Genome-editing tools provide advanced biotechnological techniques that enable the precise and efficient targeted modification of an organism’s genome. Genome-editing systems have been utilized in a wide variety of plant species to characterize gene functions and improve agricultural traits. We describe the current applications of genome editing in plants, focusing on its...

LC/MS/MS warfarin assay − An emerging tool for the early detection of cytochrome P450-associated drug−drug interactions in drug discovery

The LC/MS/MS warfarin assay, combining stereo- and regioselective cytochrome P450 (CYP) form-specific warfarin hydroxylation with sensitive and specific LC/MS/MS detection technique, is emerging to be a promising tool for the study of CYP-associated drug−drug interactions for new chemical entities (NCEs) during drug discovery process.

In vitro expansion affects the response of human bone marrow stromal cells to irradiation

BackgroundBone marrow stromal cells (BMSCs) are extensively used in regeneration therapy and cytology experiments simulate how BMSCs respond to radiation. Due to the small number and the heterogeneity of primary isolated BMSCs, extensive in vitro expansion is usually required before application, which affects the cellular characteristics and gene expression of BMSCs. However...

Development and validation of the PET-CT score for diagnosis of malignant pleural effusion

PurposeAlthough some parameters of positron emission tomography with 18F-fluorodeoxyglucose (18F-FDG) and computed tomography (PET-CT) are somehow helpful in differentiating malignant pleural effusion (MPE) from benign effusions, no individual parameter offers sufficient evidence for its implementation in the clinical practice. The aim of this study was to establish the...

Absolute stability of nonlinear systems with time delays and applications to neural networks

In this paper, absolute stability of nonlinear systems with time delays is investigated. Sufficient conditions on absolute stability are derived by using the comparison principle and differential inequalities. These conditions are simple and easy to check. In addition, exponential stability conditions for some special cases of nonlinear delay systems are discussed. Applications...

Osthole inhibits triple negative breast cancer cells by suppressing STAT3

Triple-negative breast cancer (TNBC) is an aggressive subgroup of human breast cancer. Patients with TNBC have poor clinical outcome as they are non-responsive to current targeted therapies. There is an urgent need to identify new therapeutic targets and develop more effective treatment options for TNBC patients. Osthole, a natural product from C. monnieri, has been shown to...
