The paper proposes a series of novel routing algorithms to the issue of accessing the large-scale heterogeneous information over the Internet. Different from traditional ones, the perspectives of the routing are updated in terms of the quality of information accessing, the types of resources, the dominant driver and the expected consequences. The human capital is connected to form the social capital...
We advocate the inference of qualitative information about 3D human pose, called posebits, from images. Posebits represent boolean geometric relationships between body parts (e.g., left-leg in front of right-leg or hands close to each other). The advantages of posebits as a mid-level representation are 1) for many tasks of interest, such qualitative pose information may be sufficient (e.g., semantic...
We extract heart rate and beat lengths from videos by measuring subtle head motion caused by the Newtonian reaction to the influx of blood at each beat. Our method tracks features on the head and performs principal component analysis (PCA) to decompose their trajectories into a set of component motions. It then chooses the component that best corresponds to heartbeats based on its temporal frequency...
Automated chromosome classification is an essential task in cytogenetics. The genetic disorders and abnormalities that occur to the future generation can be predicted through analysing the various characteristics of the chromosomes. The chromosome classification is mainly based on geometric and morphological features. An effective algorithm for chromosome geometric feature extraction is presented...
This paper presents electrokinetically based microfluidic integration of isolation and amplification of target-binding nucleic acids. A microfluidic device is used that consists of two microchambers for nucleic acid isolation and amplification connected by a microchannel filled with agarose gel. In the device, target-binding DNA strands are isolated and amplified on surfaces while gel-based electrophoresis...
We report a flexible electrocorticogram (ECoG) electrode array device with one directionally self-curling and -sticking properties, to solve the difficulty of the handling of thin (< 10 μm) substrate devices (Fig. 1). As the substrate, we use sandwiched parylene-N/-C which films have different linear expansion coefficients. The thermal dependences of the deflection and curvature radius of the paylene-N/-C...
This report describes preliminary results of reconstitution of an in vivo-like multi-layered placental barrier without porous membrane support. We used thin collagen membrane (10 μm in thickness, commercially available) as permeable support of placental barrier structure and cultured BeWo trophoblastic cells and HUVECs on either side of the membrane. Co-cultured cells deposited abundant basement membrane...
In this paper, we present a novel pulseoximetric sensor which can be worn in the ear channel. In previous work, we could demonstrate that measurement of heart rate (HR), arterial oxygen saturation (SpO2) and respiratory related information can be performed with reliable accuracy. Since these results were obtained under laboratory conditions, we now studied the feasibility of a clinical appliance of...
The pollen grains of different plant taxa exhibit various shapes and sizes. This structural diversity has made the identification and classification of pollen grains an important tool in many fields. Despite the myriad of applications, the classification of pollen grains is still a tedious and time-consuming process that must be performed by highly skilled specialists. In this paper, we propose an...
This paper reports the fabrication, combinatorial differentiation and analysis of embryonic bodies (EBs) in one device called “PASCL (Pneumatically Actuated Spheroids Culture Lab-on-chip)”. We demonstrated EBs formation from human adipose derived stem cells (ADSC), differentiation into adipocytes and osteoblasts and staining for differentiation monitoring all in one PASCL.
The purpose of this paper is to describe a new emerging science: Internet science. This paper argues that current Internet is a direct by-product of Shannon's Information theory and its master thesis. After that I attempt a general and generic definition of a network and discuss the different alternatives. This discussion results in defining a network as a set of distributed actors cooperating for...
We demonstrate an implantable MEMS drug delivery device to conduct controlled and on-demand, ex vivo drug transport to human eye tissue. Remotely operated drug delivery to human post-mortem eyes was performed via a MEMS device. The developed curved packaging cover conforms to the eyeball thereby preventing the eye tissue from contacting the actuating membrane. By pulsed operation of the device, using...
The increasing popularity of video consumption from mobile devices requires an effective video coding strategy. To overcome diverse communication networks, video services often need to maintain sustainable quality when the available bandwidth is limited. One of the strategy for a visually-optimised video adaptation is by implementing a region-of-interest (ROI) based scalability, whereby important...
Over the years, a large number of methods have been proposed to analyze human pose and motion information from images, videos, and recently from depth data. Most methods, however, have been evaluated on datasets that were too specific to each application, limited to a particular modality, and more importantly, captured under unknown conditions. To address these issues, we introduce the Berkeley Multimodal...
Accuracy and efficiency in geoscientific data interpretation is critically important for the resource industry, as based on these interpretations, significant financial decisions are made for exploration and extraction of resources. This study aims to understand image characteristics that impact interpreters' ability to detect geological targets within magnetic geophysics images. We use the Brain...
Spatio-Temporal interest points are the most popular feature representation in the field of action recognition. A variety of methods have been proposed to detect and describe local patches in video with several techniques reporting state of the art performance for action recognition. However, the reported results are obtained under different experimental settings with different datasets, making it...
This paper is focused on comparing corpus-based methods for estimating word sentiment. Evaluated algorithms represent varying degrees of supervision and range from regression alike approaches to more heavily supervised classifications. The main idea is to explore the opportunities arising from mining medium sized, balanced corpora -- as opposed to web as a corpus paradigm. The comparisons have been...
Recent decade has witnessed major changes on the Earth, for example, deforestation, varying cropping and human settlement patterns, and crippling damages due to disasters. Accurate damage assessment caused by major natural and anthropogenic disasters is becoming critical due to increases in human and economic loss. This increase in loss of life and severe damages can be attributed to the growing population,...
Alzheimer's disease (AD) is the most common cause of age-related dementia, which prominently affects the human connectome. Diffusion weighted imaging (DWI) provides a promising way to explore the organization of white matter fiber tracts in the human brain in a non-invasive way. However, the immense amount of data from millions of voxels of a raw diffusion map prevent an easy way to utilizable knowledge...
This paper presents a robust and fully-automatic human motion tracking system without motion priors information using a camera in a fixed location. Bottom-up estimation approaches have recently been applied to such tasks with some success. However, the performance of these approaches is limited by the difficulty of building an effective appearance model. In particular, the appearance model must be...
