A Fast and Accurate Tensor-based Optical Flow Algorithm Implemented in FPGA

Many computer vision applications require real-time processing of image data. This requirement is especially critical for autonomous vehicles performing obstacle avoidance, path planning, and target tracking tasks. A quickly calculated and relatively rough motion estimate is more useful for autonomous navigation than a more accurate, but slowly calculated estimate. Recent technology advancements in small unmanned air and ground vehicles make many low-cost surveillance and military applications possible. Most of these applications demand a low power, compact, light weight, and high speed computation platform for processing image data in real time. In most cases, the traditional general purpose processor and sequentially executed software approach does not meet these requirements. In this paper, a tensor-based optical flow algorithm is modified and implemented using field programmable gate array (FPGA) for small unmanned vehicle obstacle avoidance and navigation

Malformations of the inner auditory canal.

Malformations of the internal auditory meatus (I.A.M.) are often accompanied by other radiological abnormalities affecting the entire inner ear. In our series of cases we demonstrate solitary deformities of the IAM ranging from the stenosis of the canal (4 cases) to extreme narrowing (2 cases) or complete atresia. Another anomaly is the presence of a thick bony wall dividing the canal in two separate compartments, superior and inferior (3 cases). Most of the cases of solitary malformations were unilateral; they can be diagnosed at any age, considering that the patient has normal hearing in the opposite ear. When the malformation of the IAM occurs, associated with major deformities of the labyrinth (5 cases), we found an abnormal communication of CSF to the tympanic cavity, due to a severe anomaly of the fundus of the IAM. Meningitis is a frequent complication in patients with this abnormality.

Tunable structured illumination light sheet microscopy for background rejection and imaging depth in minimally processed tissues

We demonstrate improved optical sectioning in light sheet fluorescence microscopy using tunable structured illumination (SI) frequencies to optimize image quality in scattering specimens. The SI patterns are generated coherently using a one-dimensional spatial light modulator for maximum pattern contrast, and the pattern spatial frequency is adjustable up to half the incoherent cutoff frequency of our detection objective. At this frequency, we demonstrate background reductions of 2 orders of magnitude.

Optimization of Ferulic Acid Production From Oil Palm Frond Waste Via Enzymatic Hydrolysis Using Soil Culture

An enzymatic hydrolysis of fibre-pressed oil palm frond (FPOPF) was carried out using soil culture for ferulic&#13;\nacid production. The soil obtained from palm oil plantation was acclimatized with FPOPF substrate for 30 days&#13;\nbefore being used as soil culture. FPOPF substrate was prepared with a 1:10 ratio of FPOPF to water. By using&#13;\nDesign Expert 7, a central composite design with two factors was selected as the experimental design resulting a&#13;\ntotal of 13 runs. Two factors studied were temperature (24°C to 28°C) with 26°C as centre point, and agitation&#13;\nrate (130 rpm to 170 rpm) with centre points at 150 rpm. The ANOVA showed that the experimental design model&#13;\nwas significant. The coefficient of determination value was 0.8873, indicating that the probability this model was&#13;\nobtained through noise was 11.27%. The optimum condition obtained was temperature at 26°C and agitation rate&#13;\nat 150 rpm with a response of 205.724 mg FA/kg OPF. The optimization was repeatable with a small error of&#13;\n8.41% from validation test.

Emerging Genetic Engineering Technologies and Minnesota Agriculture

New agricultural production technologies are inherently double-edged swords. The power of the genetic engineering technologies to fundamentally redesign a plant or animal by tinkering with its genetic core is almost mind-boggling, and the opportunities and threats it carries for agriculture are enormous. In this article I ponder the nature of the structural change that is likely to result from the inevitable onset of some of these technologies. I focus especially on the implications for traditional midwestern farming.

A hemodynamic study of epidural versus intravenous anesthesia for aortofemoral bypass surgery.

The hemodynamic effects of two types of anesthesia on aortofemoral bypass surgery were studied in a randomised prospective trial. Epidural anesthesia supplemented with nitrous oxide (group I) and total intravenous anesthesia combining fentanyl and a continuous infusion of etomidate (group II) were compared. A high incidence of preoperative disease was found and all 18 patients were classified in ASA classes III-IV. It is concluded that epidural anesthesia provides excellent anesthetic and hemodynamic stability provided that an optimal filling pressure is maintained. Total intravenous anesthesia resulted in significant hypertensive reactions during surgery, which were not specifically related to crossclamping. Decreasing the high SVRI with vasodilatory treatment was necessary to treat hypertension in all those patients with preoperative hypertensive disease. No problems were seen in the intravenous group patients without preoperative hypertension. Cardiac work was higher in the intravenous group due to the high impedance of the cardiovascular system provoked by the absence of vasodilatory properties with this type of intravenous anesthesia. Monitoring of PWP and CI by Swan-Ganz catheter is shown to be very useful for optimalization of hemodynamics and fluid management especially during crossclamping, when normal Frank-Starling relationships might not be valid anymore. The effect of vasodilatory treatment, crossclamping and declamping could be carefully evaluated.

Neurotropic melanoma of the face invading the maxillary nerve

Neurotropic melanoma is a variant of desmoplastic melanoma which, in addition to a spindle‐cell vertical component and fibrosis, exhibits a lascicular growth pattern and invades cutaneous nerves. Here we describe a neurotropic melanoma which arose in a small Ientigo maligna melanoma and invaded the maxillary nerve for a distance of 5 cm. Ultrastructural features were similar to those of previously described neurotropic melanomas and tumor fascicles contained S‐100 protein and neuron‐specific enolase immunoreactivity.

Pendapatan dan Persepsi Anggota terhadap Penerapan Internal Control System pada Pertanian Padi Organik

Internal Control System (ICS) is a consolidated management concerning the effort to certify organic products. Due to its collective mechanism, farmers are able to manage its agribusiness more profitably financially. The purpose of this study was (1) to analyze the differences in income levels of farmer groups who are certified organic and non-certified organic, (2) to get an overview of the implementation of ICS in farmers group Gapoktan Simpatik, and (3) to analyze the perceptions of group members towards the implementation of ICS either certified or non-certified organic. This research was on a case study at upper stream of Cideres and Cigunungjaga watershed in the district of Sukahening, Tasikmalaya, which is a member of Gapoktan Simpatik. The analysis was performed using the R/C ratio, homogeneity analysis of data by income level using the Kolmogorov-Smirnov, analysis of income differences between the two groups of independent farmers using the Mann-Whitney test, and biplot analysis for the analysis of perceptions of group members toward ICS implementation variables. The results showed that the R/C ratio for the certified group was 1.77, and for non-certified group 1.53. The average income level of certified group was Rp19,394,800/ha/year, while the non-certified Rp12,728,940/ ha/year. The results also showed that perception toward ICS implementation of certified group was better than the non-certified. Most of the certified group respondent approached the vector of all variables, which means that they were satisfied and familiar with all the variables, while the group of respondents who were non-certified did not approach the vector. The parameters that were widely varied by respondent group responses were the certified variable of purchase, handling, processing, and export, while the most uniform response variables of the respondents were variable of organizational and ICS personnel. While the groups that were not certified provided a variety of assessment on the variables of risk management and uniform assessment on external inspection and certification.

Nocturnal Habitat Selection During Spring Migration by American Woodcock (Scolopax minor) in Central Kentucky

American woodcock (Scolopax minor) have experienced long-term population declines due to habitat loss. While significant research has occurred on breeding and wintering grounds, little is known about spring migratory ecology. This study assessed nocturnal roosting habitat of American woodcock through the use of night spotlighting techniques. The study was conducted on the Blue Grass Army Depot and the Central Kentucky Wildlife Management Area, both located in Madison County, Kentucky. A total of 84 field, 421 ha, of four habitat types, burned, grazed, hayed, old/fallow, were searched for woodcock. Roost sites were marked and the vegetation of each site was compared between age classes, sexes, and between occupied and random unoccupied locations. The following vegetation parameters were assessed: percent cover (bare soil, grass, forbs/gramanoids, shrub/sapling/vine, and litter), litter depth, dominant plant height, dominant plant species, distance to escape cover, and percent vertical cover. There was no significant difference (P > 0.05) between sexes or age classes for any of the habitat variables assessed. Logistic regression analysis indicated the best predicators of whether a woodcock would be present at a roost site were percent bare, grass, graminoids, and woody vegetation, litter depth, dominant height of vegetation, distance to escape cover, visual obstruction of escape cover from 0-20cm, and distance to field edge. To predict density of woodcocks in each field I used step-wise regression analysis, which indicated the best model for predicting woodcock density per field incorporated percent litter at roost site, litter depth, distance to escape cover, visual obstruction of escape cover from 0-20 cm, and visual obstruction of escape cover from 50-100cm. Woodcock selected fields and roost sites with varying heights of vegetation that satisfied ecological needs during spring migration, i.e. resting, loafing, breeding, foraging, predator and weather avoidance.

Simple formulation of structural similarity for halftoning and its application to Visual secret sharing

The secret sharing (SS) scheme is a cryptosystem which encrypts a secret into multiple pieces, called shares, so that only qualified combination of shares can be employed to recover the secret. The visual secret sharing (VSS) scheme is an example of SS schemes whose decryption can be performed by a human without any numerical computations. This paper is an attempt to modify the structural similarity (SSIM) index so that the modified one can measure both the structural and tonal similarities simultaneously and then to employ the modified index to give an optimization-based halftoning suitable for the encryption of VSS schemes.

TOWARD AN UNDERSTANDING OF NKT CELL BIOLOGY: Progress and Paradoxes

▪ Abstract Natural killer T (NKT) cells constitute a conserved T cell sublineage with unique properties, including reactivity for a synthetic glycolipid presented by CD1d, expression of an invariant T cell antigen receptor (TCR) α chain, and unusual requirements for thymic selection. They rapidly produce many cytokines after stimulation and thus influence diverse immune responses and pathogenic processes. Because of intensive research effort, we have learned much about factors promoting the development and survival of NKT cells, regulation of their cytokine production, and the means by which they influence dendritic cells and other cell types. Despite this progress, knowledge of the natural antigen(s) they recognize and their physiologic role remain incomplete. The activation of NKT cells paradoxically can lead either to suppression or stimulation of immune responses, and we cannot predict which will occur. Despite this uncertainty, many investigators are hopeful that immune therapies can be developed based on NKT cell stimulation.

Modification of the Velocity of Sound in Metals by an Applied Magnetic Field

An analysis is given of the change in the velocity of sound as a function of an applied magnetic field. It is found that at room temperature and for ultrasonic frequencies of a few Mc/sec, the velocity of sound increases by an amount proportional to the square of the magnetic field in agreement with the experimental results. A brief discussion is given of the change in the sound velocity as a function of a magnetic field at low temperatures.

Characterization of Slag, Fly Ash and Portland Cement for Saltstone

Batch-to-batch variability in the chemical and physical properties of the fly ash, slag and portland cement (binders) will be an ongoing concern over the many years that salt waste from Tank 50 will be processed into grout at the Saltstone Processing Facility. This batch-to-batch variability in the properties of the binder materials translates to variability in the fresh and cured properties of Saltstone. Therefore, it is important to quantify the batch-to-batch variability of the binder materials and the resultant variation in grout properties. This report is the starting point for that process by providing the baseline (reference point) binder properties to which future batches of binder materials can be compared. For this characterization effort, properties of fly ash, slag and portland cement were obtained and documented in this report. These properties included particle size distribution by laser light scattering and dry sieving, particle size and morphology by scanning electron microscopy, true, aerated and tapped densities, chemical composition, rheological properties of the water based slurries made from individual binder material, and volatility through thermogravimetric analysis and differential thermal analysis. The properties presented in this report also provide a baseline data set to assist in problem solving efforts when or if unanticipated and/or unwanted processing events occur at the Saltstone Processing Facility.

Review Preclinical trauma studies of recombinant factor VIIa

Preclinical studies in animals and ex vivo human blood have provided a solid rationale for conducting prospective randomized trials in trauma patients. Small animal models have been utilized to study the efficacy of recombinant activated factor VII (rFVIIa; NovoSeven ® ) in treating thrombocytopenic rabbits and for the reversal of anticoagulation. Safety models in the rabbit also exist to test for systemic activation of clotting and pathologic thrombosis. Animal models simulating traumatic injuries in humans have primarily been performed in pigs because of species similarities in terms of coagulation characteristics and the larger internal organs. The pig studies, utilizing human rFVIIa, have shown increased strength of clot formation, decreased bleeding, and improved survival. However, these findings are not uniform and are dependant on the model chosen. All of the animal models described have provided good safety data and suggest that the use of rFVIIa is not associated with systemic activation of coagulation or microthrombosis of end organs.

On approximation of orientation distributions by means of spherical ridgelets

Visualization and analysis of the micro-architecture of brain parenchyma by means of magnetic resonance imaging (MRI) is currently considered to be one of the most powerful methods for interrogating cerebral tissue. Unfortunately, the diffusion tensor imaging (DTI) which is standardly used for estimating the local orientations of brain fibers, is prone to substantial estimation errors whenever a voxel of interest contains more than one fiber. In such a case, a much more accurate analysis is possible using the high angular resolution diffusion imaging (HARDI) that represents local diffusion by its apparent coefficients measured as a function of orientations. In this note, a novel approach to enhancing and modeling the HARDI signals using multiresolution bases of spherical ridgelets is presented. In addition to its desirable properties of being adaptive, sparsifying, and efficiently computable, the proposed modeling leads to analytical computation of the orientation distribution functions associated with the measured diffusion, thereby providing a fast and robust analytical solution for q-ball imaging.
