UWB joint TOA and DOA estimation [PDF]

2009 IEEE International Conference on Ultra-Wideband, 2009
This paper deals with the simultaneous estimation of Time of Arrival (TOA) and Direction of Arrival (DOA) in UWB systems considering multipath propagation. The estimation is performed in the frequency domain by computing a two dimensional power delay-angle spectrum based on the periodogram because of its low computational complexity.

Probiotic strain Bacillus subtilis TO-A modulates the formation of neutrophil extracellular traps

Gut Microbes Reports
Neutrophil extracellular traps (NETs) have important innate immune functions that prevent pathogenic infections. In the intestinal tract, NET formation contributes to the prevention of the systemic spread of commensal bacteria associated with mucosal ...

EL DISEÑO Y EL LÍMITE DE SU VALIDEZ. ENTRE LA ÉTICA AMBIENTAL Y LA ÉTICA CULTURAL

Daya, 2017
El diseño como actividad y resultado de un proceso se relaciona con el contexto. Sin contexto no existe diseño, y es en esta íntima relación en que se marca la validez del producto. Se trata de un contexto complejo, definido por el ambiente y la cultura,

Improving the Performance of OTDOA based Positioning in NB-IoT Systems

, 2017
In this paper, we consider positioning with observed-time-difference-of-arrival (OTDOA) for a device deployed in long-term-evolution (LTE) based narrow-band Internet-of-things (NB-IoT) systems.

A transaction-oriented architecture for structuring unstructured information in enterprise applications [PDF]

, 2011
As 80-85% of all corporate information remains unstructured, outside of the processing scope of enterprise systems, many enterprises rely on Information Systems that cause them to risk transactions that are based on lack of information (errors of ...

Bacillus subtilis TO-A suppresses the age-related decline in locomotion in Caenorhabditis elegans

Communications Biology
Research on the role of probiotics in maintaining locomotor function in aged Caenorhabditis elegans is limited. Therefore, we investigated whether a probiotic strain, Bacillus subtilis TO-A (BSTOA), which extends the lifespan of worms can prevent age ...

Topological Orthoalgebras

, 1989
We define topological orthoalgebras (TOAs) and study their properties. While every topological orthomodular lattice is a TOA, the lattice of projections of a Hilbert space is an example of a lattice-ordered TOA that is not a toplogical lattice.

Dual Effect of Steric Hindrance in Non‐Aqueous Amine Absorbents: Navigating the Trade‐Off Between Kinetics and Thermodynamics for Efficient CO2 Capture

Advanced Science, EarlyView.
This study elucidates how steric hindrance in amines creates a dual effect in CO2 capture: it thermodynamically favors the reaction by shifting the pathway from carbamate to alkyl carbonate formation, increasing capacity and lowering regeneration heat, while simultaneously slightly slowing the kinetics.
