Efficient Road Detection and Tracking for Unmanned Aerial Vehicle (2014)

An unmanned aerial vehicle (UAV) has many applications in a variety of fields. Detection and tracking of a specific road in UAV videos play an important role in automatic UAV navigation, traffic monitoring, and ground-vehicle tracking, and also is very helpful for constructing road networks for modeling and simulation. In this paper, an efficient road detection and tracking framework in UAV videos is proposed. In particular, a graph-cut-based detection approach is given to accurately extract a specified road region during the initialization stage and in the middle of tracking process, and a fast homography-based road-tracking scheme is developed to automatically track road areas. The high efficiency of our framework is attributed to two aspects: the road detection is performed only when it is necessary and most work in locating the road is rapidly done via very fast homography-based tracking. Experiments are conducted on UAV videos of real road scenes we captured and downloaded from the Internet. The promising results indicate the effectiveness of our proposed framework, with the precision of 98.4% and processing 34 frames per second for 1046 × 595 videos on average.
Mobile cloud computing for computation offloading: Issues and challenges (2016)

Despite the evolution and enhancements that mobile devices have experienced, they are still considered as limited computing devices. Today, users become more demanding and expect to execute computational intensive applications on their smartphone devices. Therefore, Mobile Cloud Computing (MCC) integrates mobile computing and Cloud Computing (CC) in order to extend capabilities of mobile devices using offloading techniques. Computation offloading tackles limitations of Smart Mobile Devices (SMDs) such as limited battery lifetime, limited processing capabilities, and limited storage capacity by offloading the execution and workload to other rich systems with better performance and resources. This paper presents the current offloading frameworks, computation offloading techniques, and analyzes them along with their main critical issues. In addition, it explores different important parameters based on which the frameworks are implemented such as offloading method and level of partitioning. Finally, it summarizes the issues in offloading frameworks in the MCC domain that requires further research.
Multi-Party Privacy-Preserving Record Linkage using Bloom Filters (2016)

Privacy-preserving record linkage (PPRL), the problem of identifying records that correspond to the same real-world entity across several data sources held by different parties without revealing any sensitive information about these records, is increasingly being required in many real-world application areas. Examples range from public health surveillance to crime and fraud detection, and national security. Various techniques have been developed to tackle the problem of PPRL, with the majority of them considering linking data from only two sources. However, in many real-world applications data from more than two sources need to be linked. In this paper we propose a viable solution for multi-party PPRL using two efficient privacy techniques: Bloom filter encoding and distributed secure summation. Our proposed protocol efficiently identifies matching sets of records held by all data sources that have a similarity above a certain minimum threshold. While being efficient, our protocol is also secure under the semi-honest adversary model in that no party can learn any sensitive information about any other parties' data, but all parties learn which of their records have a high similarity with records held by the other parties. We evaluate our protocol on a large real voter registration database showing the scalability, linkage quality, and privacy of our approach.
Filtering to Match Hearing Aid Insertion Gain to Individual Ear Acoustics (2009)

When hearing aid gain is prescribed by software, gain is calculated based on the average acoustics for the age of patient, gender, mold type, and so on. The acoustics of the individual's ear often vary from the average values, so there will be a mismatch between the prescribed gain and the real-ear gain. Real-ear measurement can be used to verify the gain and adjust it to meet targets, but the quality of the match will be limited by the number of channels and the flexibility of the hearing aid. A potential way to improve this process is to generate a filter that compensates for variations in real-ear insertion gain due to individual ear acoustics. Such a filter could be included in the processing path of a digital hearing aid. This article describes how such a filter can be generated using the windowing method, and the principle is demonstrated in a real ear. The approach requires communication between the real-ear measurement and hearing aid programming software. A finite impulse response filter with group delay just over 2 ms matched insertion gain to target values within the acceptable tolerance defined by British Society of Audiology guidelines.

Study on Environmental Sensitivity of Variety in Rice (2002)

According to sensitivity to environment, rice varieties can be classified into a strong environmentally sensitive variety, a weak environmentally sensitive variety and an environmentally insensitive variety.The general method that was used to evaluate the environmental sensitivity (ES) of rice variety was put forward in this paper. ESs of varieties were evaluated as follows: (1)ES of indica-japonica hybird rice was more sensitive than that of japonica rice. (2)The order of ESs of japonica type varieties was medium-maturing late japonica variety ＞ early-maturing late japonica variety ＞ late-maturing medium japonica variety ＞ medium-maturing medium japonica variety. (3)There was a significant difference in ESs among varieties of the same japonica type rice, too. Some problems, such as the principles of rather late-maturing rice planted northward,were also discussed at the end of this paper.
FoodSQRBlock: Digitizing Food Production and the Supply Chain with Blockchain and QR Code in the Cloud (2021)

Food safety is an important issue in today’s world. The traditional agri-food production system does not offer easy traceability of the produce at any point of the supply chain, and hence, during a food-borne outbreak, it is very difficult to sift through food production data to track produce and the origin of the outbreak. In recent years, the blockchain based food production system has resolved this challenge; however, none of the proposed methodologies makes the food production data easily accessible, traceable and verifiable by consumers or producers using mobile/edge devices. In this paper, we propose FoodSQRBlock (Food Safety Quick Response Block), a blockchain technology based framework that digitises the food production information and makes it easily accessible, traceable and verifiable by the consumers and producers by using QR codes. We also propose a large-scale integration of FoodSQRBlock in the cloud to show the feasibility and scalability of the framework, as well as give an experimental evaluation to prove this.
Magnetic and Microwave Properties of Calcium Vanadium-Substituted Garnets (1966)

Polycrystalline ferrimagnetic pentavalent vanadium garnet compositions conforming to the general formula {Y3−2xCa2x} [Fe2] (Fe3−xVx) O12 for x equal 0 to 1.5 were investigated and evaluated along with the ``yttrium-rare-earth-free'' garnets of the system {Bi3−2yCa2y} [Fe2] (Fe3−yVy) O12 for y equal 0.75 to 1.5. Single crystals of the latter system have been investigated for 1.0&lt;y≦1.4. Magnetic and microwave properties are reported. In the (Bi-Y)CaVIG compounds, 4πMs values from 1780 G to zero are covered. Linewidths increased approximately as M−1 for values of x=0 to 1; for x&gt;1.0 to 1.5, linewidth values are 100 to 200 Oe. In the BiCaVIG compounds, the linewidths are higher (500 Oe) for values of y&lt;1.0 and approximately 200 Oe for 1.0&lt;y≦1.5. Dielectric constants (X band) for these compounds varied from 29 to 13 for y=0.75 to y=1.5, respectively. Compositions in both systems were prepared possessing dielectric loss tangents (X band) as low as 0.0001. The temperature characteristics of these vanadium garnets are compared to the more widely used yttrium aluminum and yttrium gadolinium iron garnets. Single-crystal samples (y=1.33, 4πMs=500 G) were prepared possessing measured linewidths at C band of 1.0 Oe.
Compact Pulsed Generator of Fast Neutrons (1960)

A study of the factors influencing the design of pulsed neutron generators is made. By using the reaction between tritium and deuterium, peak rates of 1013/sec should be obtainable from quite small sources. A method of keeping the pressure of deuterium gas substantially constant at the working pressure was evolved. This enabled a ``sealed-off'' and hence portable source to be made. The development of a fast neutron generator or neutron tube based on these considerations is described. This was capable of producing neutrons at a rate of 5×1012/sec at a voltage of 100 kv. The tube was suitable for operation at pulse lengths of 20 μsec, and the neutron content of each pulse was 108. No difficulty was experienced in operating at 1 pulse/sec, and higher pulse repetition frequencies may be possible.

Gene therapy for malignant glioma (2006)

Glioblastoma multiforme represents the most common primary malignant tumor of the adult CNS. Unfortunately, the median survival after surgical intervention alone is less than 6 months and the addition of radiotherapy can extend this time to only 9 months. Consequently, efforts aimed at developing new therapies have focused on new treatment strategies that specifically target tumor cells and spare normal cells. One such modality, gene therapy, has shown promise in the spectrum of agents utilized against brain tumors. This review highlights the principles of gene therapy and discusses the results of recent clinical trials in which gene therapy has been employed against malignant brain tumors.

A new voice transformation method based on both linear and nonlinear prediction analysis (2002)

We describe a voice transformation method which changes the source speaker's acoustic features to those of a target speaker. In the method acoustic features are divided into two parts, linear and nonlinear parts. Linear parts are characterized by LPC cepstrum coefficients which are obtained from LP analysis. The nonlinear part, which represents the excitation signal, is modelled by the long-delay nonlinear predictor using a neural net. Conversion rules for the excitation signal are generated by the average pitch ratio and the mapping codebook, and those for LPC cepstrum coefficients are based on the orthogonal vector space conversion. In addition, the spectral envelope compensation is proposed to correct spectral distortion. In the transformed speech a listening test shows that the proposed method makes it possible to convert speaker's individuality while maintaining high quality.
Focal and segmental glomerulosclerosis induced in mice lacking decay-accelerating factor in T cells (2009)

Heritable and acquired diseases of podocytes can result in focal and segmental glomerulosclerosis (FSGS). We modeled FSGS by passively transferring mouse podocyte-specific sheep Abs into BALB/c mice. BALB/c mice deficient in the key complement regulator, decay-accelerating factor (DAF), but not WT or CD59-deficient BALB/c mice developed histological and ultrastructural features of FSGS, marked albuminuria, periglomerular monocytic and T cell inflammation, and enhanced T cell reactivity to sheep IgG. All of these findings, which are characteristic of FSGS, were substantially reduced by depleting CD4+ T cells from Daf(-/-) mice. Furthermore, WT kidneys transplanted into Daf(-/-) recipients and kidneys of DAF-sufficient but T cell-deficient Balb/(cnu/nu) mice reconstituted with Daf(-/-) T cells developed FSGS. In contrast, DAF-deficient kidneys in WT hosts and Balb/(cnu/nu) mice reconstituted with DAF-sufficient T cells did not develop FSGS. Thus, we have described what we believe to be a novel mouse model of FSGS attributable to DAF-deficient T cell immune responses. These findings add to growing evidence that complement-derived signals shape T cell responses, since T cells that recognize sheep Abs bound to podocytes can lead to cellular injury and development of FSGS.
Imaging mass spectrometry to discriminate breast from pancreatic cancer metastasis in formalin‐fixed paraffin‐embedded tissues (2014)

Diagnosis of the origin of metastasis is mandatory for adequate therapy. In the past, classification of tumors was based on histology (morphological expression of a complex protein pattern), while supportive immunohistochemical investigation relied only on few "tumor specific" proteins. At present, histopathological diagnosis is based on clinical information, morphology, immunohistochemistry, and may include molecular methods. This process is complex, expensive, requires an experienced pathologist and may be time consuming. Currently, proteomic methods have been introduced in various clinical disciplines. MALDI imaging MS combines detection of numerous proteins with morphological features, and seems to be the ideal tool for objective and fast histopathological tumor classification. To study a special tumor type and to identify predictive patterns that could discriminate metastatic breast from pancreatic carcinoma MALDI imaging MS was applied to multitissue paraffin blocks. A statistical classification model was created using a training set of primary carcinoma biopsies. This model was validated on two testing sets of different breast and pancreatic carcinoma specimens. We could discern breast from pancreatic primary tumors with an overall accuracy of 83.38%, a sensitivity of 85.95% and a specificity of 76.96%. Furthermore, breast and pancreatic liver metastases were tested and classified correctly.

Radiocontrast-induced acute renal failure: allocations and outcomes. (2001)

Radiocontrast-induced nephropathy causes significant morbidity and mortality with increase in hospital length of stay and costs. It can be largely prevented by identifying the patients at risk before the procedure. Once the at-risk patient is identified, ways to prevent the development of acute renal failure are: avoiding volume depletion, aggressive saline hydration with the aim of keeping the urine output over 150 mL/hour, and the use of low-osmolality contrast agents, with as little volume used as possible. There is theoretical potential for the dopamine DA1 agonist fenoldopam as a preventive agent, and this is currently being tested in randomized trials.
Ambipolar MoS<sub>2</sub> Thin Flake Transistors (2012)

Field effect transistors (FETs) made of thin flake single crystals isolated from layered materials have attracted growing interest since the success of graphene. Here, we report the fabrication of an electric double layer transistor (EDLT, a FET gated by ionic liquids) using a thin flake of MoS(2), a member of the transition metal dichalcogenides, an archetypal layered material. The EDLT of the thin flake MoS(2) unambiguously displayed ambipolar operation, in contrast to its commonly known bulk property as an n-type semiconductor. High-performance transistor operation characterized by a large "ON" state conductivity in the order of ~mS and a high on/off ratio >10(2) was realized for both hole and electron transport. Hall effect measurements revealed mobility of 44 and 86 cm(2) V(-1) s(-1) for electron and hole, respectively. The hole mobility is twice the value of the electron mobility, and the density of accumulated carrier reached 1 × 10(14) cm(-2), which is 1 order of magnitude larger than conventional FETs with solid dielectrics. The high-density carriers of both holes and electrons can create metallic transport in the MoS(2) channel. The present result is not only important for device applications with new functionalities, but the method itself would also act as a protocol to study this class of material for a broader scope of possibilities in accessing their unexplored properties.

Local Heating in Nanoscale Conductors (2003)

We report first-principles calculations of local heating in nanoscale junctions formed by a single molecule and a gold point contact. Due to the lower current density and larger heat dissipation, the single molecule heats less than the gold point contact. We also find that, at zero temperature, threshold biases, Vonset, of about 6 mV and 11 mV for the molecule and the point contact, respectively, are required to excite the smallest vibrational mode and generate heat. The latter estimate is in very good agreement with recent experimental results on the same system. At a given external bias V below Vonset, heating becomes noticeable when the background temperature is on the order of approximately e(Vonset − V)/kB. Above Vonset, local heating increases dramatically with increasing bias, mainly due to excitation of longitudinal modes, but is also considerably suppressed by thermal dissipation into the electrodes, provided good thermal contacts exist between the nanostructure and the bulk electrodes.
Characterizing Fractures with Multicomponent Induction Measurements (2005)

The capability of a multicomponent induction measurement to detect fractures around boreholes is studied using both numerical simulation and field data analysis. With examples given for hydraulically induced fractures, our numerical simulation shows that coplanar-coil induction measurements (σ xx and σ yy , where the x-axis is parallel to and the y-axis is perpendicular to the fracture plane) provide unique value for detecting the fractures that a coaxial-array measurement (σ zz ) does not have. For a resistive fracture, σ xx is much more sensitive to shallow fractures than σ zz . In contrast, if a fracture is filled with materials more conductive than the surrounding formation, only the σ yy measurement can provide information about the existence of the fracture. Field data from a Gulf of Mexico well drilled with oil base mud shows the capability of the multicomponent induction measurement, especially σ xx and σ yy , to detect hydraulic fractures. The existence of the fractures is confirmed independently by crossed-dipole acoustic and Stoneley wave measurements. The crossed-dipole acoustic and multicomponent induction measurements are further combined to jointly characterize the fractures. More specifically, the crossed-dipole acoustic measurement is used to determine the fracture azimuth, and the difference between the σ xx and σ yy induction measurements is applied to estimate the fracture length using the fracture azimuth as an input.
Salicylhydroxamic acid inhibits myeloperoxidase activity (1991)

Salicylhydroxamic and benzohydroxamic acids were found to bind to the resting state of myeloperoxidase and inhibit ligand binding to the heme iron. An ionizable group on the enzyme with pKa = 4 affects salicylhydroxamic acid binding; binding occurs when this group is not protonated. The binding of the heme iron ligands (e.g. cyanide, nitrite, and chloride) is probably controlled by the same ionizable group. The equilibrium dissociation constant of the salicylhydroxamic acid-myeloperoxidase complex is about 2 x 10(-6) M, and the association rate constant is 7.4 x 10(6) M-1.s-1. Salicylhydroxamic acid serves as a donor to the higher oxidation state of myeloperoxidase and thereby inhibits guaiacol oxidation. Salicylhydroxamic acid was also found to bind to intestinal peroxidase and lactoperoxidase. Salicylhydroxamic acid binding to all three mammalian peroxidases was about 3 orders of magnitude stronger than benzohydroxamic acid binding. We conclude that the salicylhydroxamic and benzohydroxamic acids bind in the distal heme cavity of these peroxidases and interact with the heme ligand binding site.
