Future space surveillance requires dealing with uncertainties directly in the initial orbit determination phase. We propose an approach based on Taylor differential algebra to both solve the initial orbit determination (IOD) problem and to map uncertainties from the observables space into the orbital elements space. This is achieved by approximating in Taylor series the general formula for pdf ...

Abstract Recent studies suggest that tropical Indian Ocean sea surface temperature (SST) anomalies, especially those associated with the Dipole (IOD), may trigger Atlantic Niño through atmospheric teleconnection. However, it remains unclear whether former has an impact on prediction skill of latter. This work applies hindcasts from 21 operational seasonal forecast systems based dynamical climat...

The Indian Ocean has sustained robust surface warming in recent decades, but the role of multidecadal variability remains unclear. Using ocean model hindcasts, characteristics of low-frequency Indian Ocean temperature variations are explored. Simulated upper-ocean temperature changes across the IndianOcean in the hindcast are consistent with those recorded in observational products and ocean re...

The twentieth-century simulations using by 17 coupled ocean–atmosphere general circulation models (CGCMs) submitted to the Intergovernmental Panel on Climate Change’s Fourth Assessment Report (IPCC AR4) are evaluated for their skill in reproducing the observed modes of Indian Ocean (IO) climate variability. Most models successfully capture the IO’s delayed, basinwide warming response a few mont...

Drought patterns across monsoon and temperate Asia over the period 1877–2005 are linked to IndoPacific climate variability associated with the El NiñoSouthern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). Using the Monsoon Asia Drought Atlas (MADA) composed of a high-resolution network of hydroclimatically sensitive tree-ring records with a focus on the June– August months, spatial drou...

A basinwide warming (cooling) in the Indian Ocean is observed following the El Niño (La Niña) mature phase, with the amplitude of the warming being significantly larger than the cooling. A composite analysis reveals that the amplitude asymmetry (positive skewness) between the warm and cold Indian Ocean basinwide sea surface temperature anomaly pattern (IOB) appears only when ENSO is concurrent ...

The objective of the present study was to investigate whether tissue inhibitor of metalloproteinase-3 (TIMP-3), pituitary adenylate cyclase-activating polypeptide (PACAP), and vasoactive intestinal peptide (VIP) participate in the occurrence of female stress urinary incontinence (SUI) by measuring the expression levels of TIMP-3, PACAP, and VIP in the vaginal wall and analyzing their correlatio...

12 The impact of Indo-Pacific climate feedback on the dynamics of El Niño Southern Oscil13 lation (ENSO) is investigated using an ensemble set of Indian Ocean decoupling experiments 14 (DCPL), utilising a millennial integration of a coupled climate model. It is found that elim15 inating air-sea interactions over the Indian Ocean results in stronger ENSO variability with 16 various degrees of am...

Due to wide-spread use of the Information and Communications Technology (ICT) Internet Things (IoT) enabled smart devices, called unmanned aerial vehicles (UAVs) (popularly known as drones), a lot potential applications Drones (IoD) are available ranging from military civilian applications. Access control mechanism is an important security service that needed secure communication among drones i...
