A Robust TCPHD Filter for Multi-Sensor Multitarget Tracking Based on a Gaussian–Student’s t-Mixture Model

open access: yesRemote Sensing
To realize multitarget trajectory tracking under non-Gaussian heavy-tailed noise, we propose a Gaussian–Student t-mixture distribution-based trajectory cardinality probability hypothesis density filter (GSTM-TCPHD).

Ferritin‐Doped Nanoparticles Triggered Tumor‐Specific Darkening for Enhanced Photothermal Tumor Ablation and Immune Activation

open access: yesAdvanced Healthcare Materials, EarlyView.
Ferritin‐doped hybrid nanoparticles triggered accurate tumor‐specific hemorrhage for enhanced in situ photothermal therapy and evoked anti‐tumor immunity. Notably, HFn/GA‐Fe specifically induced tumor hemorrhage 12 h after intravenous injection, resulting in visible color darkening. Through photoacoustic imaging, tumor vessels could be clearly observed

Set Membership Adaptive Non Parametric Identification of Non-Linear Systems

open access: yesIEEE Access
Adaptation is a desirable feature when dealing with the identification of complex systems. However, this property can be difficult to achieve when non-convex model structures such as neural networks are employed to parametrize the unknown system.

Benchmarking Organic Photodiodes at the Noise Floor

open access: yesAdvanced Optical Materials, EarlyView.
A precise measurement framework based on a calibrated, ultra‐low‐noise automated setup with open‐source Python scripts enables accurate benchmarking of photodiodes. The unique combination of time‐dependent current measurement under dark conditions, followed by continuous‐wave faint illumination, facilitates reliable extraction of photocurrent near ...

Set-related restrictions for semantic groupings [PDF]

open access: yes, 1989
Semantic database models utilize several fundamental forms of groupings to increase their expressive power. In this paper we consider four of the most common of these constructs; basic set groupings, is-a related groupings, power set groupings, and ...

Transformation From Semantic Data Model to Rdf [PDF]

open access: yes, 2004
There have been several efforts to use relational model and database to store and manipulate Resource Description Framework (RDF). They have one general disadvantage, i.e.

Improving the Robustness of Visual Teach‐and‐Repeat Navigation Using Drift Error Correction and Event‐Based Vision for Low‐Light Environments

open access: yesAdvanced Robotics Research, EarlyView.
Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

Transforming N-ary relationships to database schemas: an old and forgotten problem [PDF]

open access: yes, 2002
The N-ary relationships, have been traditionally a source of confusion and still are. One important source of confusion is that the term cardinality in a relationship has several interpretations, two of them being very popular.
