摘要： Despite rapid advances in the study of brain–computer interfaces (BCIs) in recent decades, two fundamental challenges, namely, improvement of target detection performance and multidimensional control, continue to be major barriers for further development and applications. In this paper, we review the recent progress in multimodal BCIs (also called hybrid BCIs), which may provide potential solutions for addressing these challenges. In particular, improved target detection can be achieved by developing multimodal BCIs that utilize multiple brain patterns, multimodal signals, or multisensory stimuli. Furthermore, multidimensional object control can be accomplished by generating multiple control signals from different brain patterns or signal modalities. Here, we highlight several representative multimodal BCI systems by analyzing their paradigm designs, detection/control methods, and experimental results. To demonstrate their practicality, we report several initial clinical applications of these multimodal BCI systems, including awareness evaluation/detection in patients with disorder of consciousness (DOC). As an evolving research area, the study of multimodal BCIs is increasingly requiring more synergetic efforts from multiple disciplines for the exploration of the underlying brain mechanisms, the design of new effective paradigms and means of neurofeedback, and the expansion of the clinical applications of these systems.

摘要： This paper reports the outcomes of the 2014 Data Fusion Contest organized by the Image Analysis and Data Fusion Technical Committee (IADF TC) of the IEEE Geoscience and Remote Sensing Society (IEEE GRSS). As for previous years, the IADF TC organized a data fusion contest aiming at fostering new ideas and solutions for multisource remote sensing studies. In the 2014 edition, participants considered multiresolution and multi-sensor fusion between optical data acquired at 20-cm resolution and long-wave (thermal) infrared hyperspectral data at 1-m resolution. The Contest was proposed as a double-track competition: one aiming at accurate landcover classification and the other seeking innovation in the fusion of thermal hyperspectral and color data. In this paper, the results obtained by the winners of both tracks are presented and discussed.

A Nanosystem Loaded Perfluorohexane and Rose Bengal Coupled Upconversion Nanoparticles for Multimodal Imaging and Synergetic Chemo-Photodynamic Therapy in Cancer
摘要： Theranostics is a new trend integrating diagnostic and therapeutic functions in tumour research. Theranostic nanoparticles that enabling both tumour imaging and drug delivery are a promising platform for image-guided cancer therapy. Photodynamic therapy (PDT) has great potential in synergy with traditional chemotherapy while facing great challenges due to hypoxia, poor targeting ability and limited penetration depth of visible light. To solve these problems, we presented a novel nanosystem of FA/UCNPs-RB/HCPT/PFH@Lipid (denoted as FURH-PFH-NPs), with a perfluorohexane (PFH) carrying rich oxygen core and a folic acid-modified lipid shell. The shell contains 10-hydroxycamptothecin (HCPT) and self-fluorescing photosensitizer compounds, namely, of upconversion nanoparticles and Rose Bengal (UCNPs-RB). In this study, FURH-PFH-NPs aggregated at SKOV3 cells (in vitro) and the nude xenograft tumour region when combined with folic acid receptor. When triggered by low-intensity focused ultrasound (LIFU), FURH-PFH-NPs released PFH, UCNPs-RB and HCPT. The above procedure was monitored through multimodal imaging, which simultaneously guided the tumour therapy. UCNPs-RB and PFH promoted the PDT effect under LIFU. Through PDT and HCPT, we obtained better therapeutic effects and good biosafety in SKOV3 nude xenograft tumours. FURH-PFH-NPs combined with LIFU and laser irradiation might be a promising strategy for ovarian cancer.

Low-Power, Multimodal Laser Micromachining of Materials for Applications in sub-5 ?μm Shadow Masks and sub-10 ?μm Interdigitated Electrodes (IDEs) Fabrication
摘要： Laser micromachining is a direct write microfabrication technology that has several advantages over traditional micro/nanofabrication techniques. In this paper, we present a comprehensive characterization of a QuikLaze 50ST2 multimodal laser micromachining tool by determining the ablation characteristics of six (6) different materials and demonstrating two applications. Both the thermodynamic theoretical and experimental ablation characteristics of stainless steel (SS) and aluminum are examined at 1064 nm, silicon and polydimethylsiloxane (PDMS) at 532 nm, and Kapton? and polyethylene terephthalate at 355 nm. We found that the experimental data aligned well with the theoretical analysis. Additionally, two applications of this multimodal laser micromachining technology are demonstrated: shadow masking down to approximately 1.5 μm feature sizes and interdigitated electrode (IDE) fabrication down to 7 μm electrode gap width.

Analysis and design of a hybrid optical fiber refractometer for large dynamic range measurements
摘要： In this paper, we report the outcomes of the 2015 data fusion contest organized by the Image Analysis and Data Fusion Technical Committee (IADF TC) of the IEEE Geoscience and Remote Sensing Society. As for previous years, the IADF TC organized a data fusion contest aiming at fostering new ideas and solutions for multisource studies. The 2015 edition of the contest proposed a multiresolution and multisensorial challenge involving extremely high resolution RGB images (with a ground sample distance of 5 cm) and a 3-D light detection and ranging point cloud (with a point cloud density of approximatively 65 pts/m2 ). The competition was framed in two parallel tracks, considering 2-D and 3-D products, respectively. In this Part B, we report the results obtained by the winners of the 3-D contest, which explored challenging tasks of road extraction and ISO containers identi?cation, respectively. The 2-D part of the contest and a detailed presentation of the dataset are discussed in Part A.

Research of Multimodal Medical Image Fusion Based on Parameter-Adaptive Pulse-Coupled Neural Network and Convolutional Sparse Representation
摘要： Visual effects of medical image have a great impact on clinical assistant diagnosis. At present, medical image fusion has become a powerful means of clinical application. The traditional medical image fusion methods have the problem of poor fusion results due to the loss of detailed feature information during fusion. To deal with it, this paper proposes a new multimodal medical image fusion method based on the imaging characteristics of medical images. In the proposed method, the non-subsampled shearlet transform (NSST) decomposition is first performed on the source images to obtain high-frequency and low-frequency coefficients. The high-frequency coefficients are fused by a parameter-adaptive pulse-coupled neural network (PAPCNN) model. The method is based on parameter adaptive and optimized connection strength β adopted to promote the performance. The low-frequency coefficients are merged by the convolutional sparse representation (CSR) model. The experimental results show that the proposed method solves the problems of difficult parameter setting and poor detail preservation of sparse representation during image fusion in traditional PCNN algorithms, and it has significant advantages in visual effect and objective indices compared with the existing mainstream fusion algorithms.

Flexible and Degradable Multimodal Sensor Fabricated by Transferring Laser-Induced Porous Carbon on Starch Film
摘要： Flexible sensors (FSs) hold great potential in wearable and intelligent equipment, but the preparation of degradable and multimodal FSs is urgently demanded, which may simplify the sensor matrix and reduce electronic waste. Here in this work, a multimodal and degradable FS was fabricated by transferring laser-induced porous carbon onto starch film. The obtained sensor showed three modes that can detect strain (with gauge factor (GF) = 134.2, response time of 130 ms, and stability >1000 times), temperature (25?90 °C), and pressure (0?250 kPa). The sensor can be used for monitoring human motions, detection of spatial pressure, and multiple stimuli. More importantly, the sensor was demonstrated to be degradable in water, suggesting it is a "green" electronic device being free of electronic pollution. This kind of multimodal and degradable FS may find wide applications in health and sports monitoring, flexible electronics, artificial intelligence, and so on.

Evaluation of Retinal Pigment Epithelium and Choroidal Neovascularization in Rats Using Laser-Scanning Optical-Resolution Photoacoustic Microscopy
摘要： Purpose: To demonstrate the value of the laser-scanning optical-resolution (LSOR)-photoacoustic (PA) microscopy (PAM) system and the conventional multimodal imaging techniques in the evaluation of laser-induced retinal injury and choroidal neovascularization (CNV) in rats. Methods: Different degrees of retinal injury were induced using laser photocoagulation. We compared the LSOR-PAM system with conventional imaging techniques in evaluating retinal injury with or without CNV. Six additional rats, treated with an anti-VEGF antibody or immunoglobulin G immediately after photocoagulation, were imaged 7 and 14 days after injection, and CNV lesion areas were compared. Results: In the retinal injury model, fundus autofluorescence showed well-defined hyperreflection, while the lesion displayed abundant PA signals demonstrating nonuniform melanin distribution in retinal pigment epithelium (RPE). RPE was detected with higher contrast in the PAM B-scan image than optical coherence tomography (OCT). Additionally, the CNV lesion was present with multiple PA signal intensi- ties which distinctly characterized the location and area of CNV as found in fundus fluorescein angiography. Further- more, the decreased PA signals extending from the CNV le- sion were similar to those of the vascular bud in ex vivo im- aging, which was invisible in other in vivo images. When treated with anti-VEGF agents, statistically significant differ- ences can be demonstrated by PAM similar to other mo- dalities. Conclusions: LSOR-PAM can detect the melanin distribution of RPE in laser-induced retinal injury and CNV in rats. PAM imaging provides a potential new tool to evalu- ate the vitality and functionality of RPE in vivo as well as to monitor the development and treatment of CNV.

Janus shaped plasmonic-magnetic silver-magnetite nanostructures for multimodal applications
摘要： The multifunctional biocompatible Janus shaped plasmonic-magnetic silver-magnetite nanoparticles have been developed via a single phase microemulsion technique and investigated for different physical properties. The noble metal integration with magnetite nanoparticles introduces superior optical properties into the nanostructures. The dynamic light scattering technique has been used to measure the hydrodynamic size, monodispersity and zeta potential to check their suitability as multimodal agents. The synthesized silver-magnetite nanoparticles are monodispersed and possess colloidal stability. The UV–visible spectra for Janus silver-magnetite nanoparticles shows a surface plasmon resonance peak at 372 and 474 nm which lies in the visible region of electromagnetic spectrum. The photoluminescence spectrum confirms the obtained nanoparticles to be optically active. The measurements of response for bare magnetite as well as silver-magnetite nanoparticles in an alternating magnetic field reveal their suitability in hyperthermia applications. These synthesized integrated magnetite-silver nanostructures show its potential as an excellent candidate for multimodal applications.
