Extracting Terrain Features from Range Images for Autonomous Random Stepfield Traversal (2007)

One of the challenges of rescue robotics is to create robots that can autonomously traverse rough, unstructured terrain. Although mechanical engineering can produce very capable robots, mechanical engineering alone will not drive them. In this paper, we present a terrain feature extractor that can be taught to find significant features in range images of terrain around a robot from a human expert. This novel approach has the advantage that it potentially allows the human expert's knowledge to be captured rapidly. A terrain model is generated from the many points in the range sensor data. Techniques from the field of knowledge acquisition are then used to find patterns in the terrain model. A knowledge acquisition system can then be taught to drive a robot in unstructured terrain based on these features. We evaluate the performance of the initial stages of the feature extractor on a real robot, traversing NIST specification red stepfields.

Somatic SMAD3-activating mutations cause melorheostosis by up-regulating the TGF-β/SMAD pathway (2020)

Melorheostosis is a rare sclerosing dysostosis characterized by asymmetric exuberant bone formation. Recently, we reported that somatic mosaicism for MAP2K1-activating mutations causes radiographical "dripping candle wax" melorheostosis. We now report somatic SMAD3 mutations in bone lesions of four unrelated patients with endosteal pattern melorheostosis. In vitro, the SMAD3 mutations stimulated the TGF-β pathway in osteoblasts, enhanced nuclear translocation and target gene expression, and inhibited proliferation. Osteoblast differentiation and mineralization were stimulated by the SMAD3 mutation, consistent with higher mineralization in affected than in unaffected bone, but differing from MAP2K1 mutation-positive melorheostosis. Conversely, osteoblast differentiation and mineralization were inhibited when osteogenesis of affected osteoblasts was driven in the presence of BMP2. Transcriptome profiling displayed that TGF-β pathway activation and ossification-related processes were significantly influenced by the SMAD3 mutation. Co-expression clustering illuminated melorheostosis pathophysiology, including alterations in ECM organization, cell growth, and interferon signaling. These data reveal antagonism of TGF-β/SMAD3 activation by BMP signaling in SMAD3 mutation-positive endosteal melorheostosis, which may guide future therapies.
Policies for Migration of Real-Time tasks in Embedded Multicore Systems (2010)

The increasing computational and power demands of embedded systems today are being met by deploying multicore architectures. Several embedded systems have real-time requirements that necessitate offline temporal guarantees. The use of multicores in such systems poses a challenge in terms of timing predictability, specifically when real-time tasks are permitted to migrate among the different cores. The aim of this paper is to put forth novel policies to guide migration decisions on time-critical and safetycritical embedded systems that use multicore architectures. Migration decisions are based on the cache usage of tasks, the migration mechanisms available and the characteristics of the network-on-chip (NoC) that is used to provide communication among cores. 1
Development of Micro-Lens for High Density Small Form Factor Optical Pickup (2005)

The miniaturization of high recording density optical disc drives (ODDs) like BD enables them to be adopted to the portable devices like camcorder, digital camera, portable game player and mp3 player, and the related researches were reported [1,2], In these topics, the miniaturization of the optical pickup is the key issue because it is impossible to make a miniaturized ODD without the miniaturization of the optical pickup.
Reduced graphene oxides: the thinnest and most lightweight materials with highly efficient microwave attenuation performances of the carbon world (2014)

In this work, reduced graphene oxide (r-GO) and graphite nanosheet (GN) were obtained via the chemical approach. Furthermore, r-GO composites and GN composites were prepared with a paraffin wax host. r-GO composites show high dielectric properties and electromagnetic interference shielding efficiency (EMI SE). Compared with the GN composites, the loss tangent and EMI SE of the r-GO composites with the same mass ratio are enhanced ∼5 to 10 times and ∼3 to 10 times, respectively. The enhanced attenuation capacity arises from higher specific surface area, clustered defects and residual bonds of the r-GOs, which increase the polarization loss, scattering and conductivity of the composite. Moreover, the higher conductivity of r-GO composites leads to higher EMI SE compared with that of GN composites. These results suggest that r-GOs are highly promising fillers for microwave attenuation in the carbon family and that r-GO composites are high-performance EMI shielding materials with application anticipated to many fields.
Properties of pressure‐sensitive adhesive tapes with soft adhesives to human skin and their mechanism (2007)

As the softness of adhesives increased, the peeling force against a general stainless-steel panel with a flat surface decreased, although the peeling force against human skin did not significantly change. The amount of stripped corneocytes on the removed tapes and the level of pain when the tapes were removed decreased with the increase in softness of the adhesives. These results suggest that adhesive tapes with soft adhesives that contain isopropyl myristate as a softener are suitable for the skin. Furthermore, the degree of penetration of adhesive into the sulcus cutis increased as the softness of adhesives increased. Upon evaluation of the peeling force against the model panels, as the softness of adhesives increased, there was a slight decrease in the peeling force against the skin model panel, while there was a remarkable decrease in the peeling force against the crista cutis model panel. These results suggest that the lack of change in the dermal peeling force as the softness of adhesives increased was caused by penetration of soft adhesive into the sulcus cutis, and that the decrease in the amount of stripped corneocytes was caused by a decrease in the peeling force against the crista cutis, which consists of corneocytes mainly removed by the tapes.
Hydrostatic Pressure as a Structural and Mechanistic Probe of Tryptophan Synthase and Tryptophan Indole‐lyase (2006)

The effects of hydrostatic pressure on the conformation and activity of tryptophan (Trp) synthase α 2 β 2 complex from Salmonella typhimurium and tryptophan indole‐lyase (Trpase) from Escherichia coli have been examined. The data demonstrate that the open conformation of Trp synthase is favored by higher pressure. The ΔV o and K o for the equilibrium between the closed and open conformations of the Trp synthase‐L‐Ser complex are −126 mL/mol and 0.12 for the Na + form and −171 mL/mol and 2.3 x 10 −4 for the NH 4 + form. Pressure‐jump experiments of the H463F mutant Trpase L‐Trp and L‐Met complexes show relaxations at 500 nm after rapid pressure changes of 100–400 bar for the complexes with both L‐Trp and L‐Met. However, the apparent rate constants for relaxation of L‐Trp, but not L‐Met, show a significant increase with pressure. These results suggest that there may be a contribution to the deprotonation reaction of Trpase either from quantum mechanical tunneling or from a mechanical coupling of protein motion and proton transfer for the reaction of L‐Trp, but not with L‐Met.
An Improved LEACH Algorithm (2018)

In1 the wireless sensor network, the sensor network has the problem of energy constraints. One of its important objectives is the energy of sensor nodes can be used efficiently, and the lifetime of the whole network system can be extended on the premise of completing the requirement of application. In this paper, the wireless sensor backbone routing algorithm is proposed. The algorithm mainly projects the distance between the next node of the transmission information and the current node, and projects it onto the line connecting the current node and the Sink node, and the projection can be converted into the energy by formula, by adding the projection's energy and the remaining energy of next transmission information's node. the sum of energy which is the largest one can be find in those next node. Through experimental simulation analysis, we can conclude that the improved LEACH algorithm can make full use of the energy in the network and the life cycle of the network can be extended.

Controlled One‐pot Synthesis of PdAg Nanoparticles and Their Application in the Semi‐hydrogenation of Acetylene in Ethylene‐rich Mixtures (2022)

Abstract In the present paper, we report the synthesis of highly functionalized nanomaterials carefully nanoengineered to catalyze the semi‐hydrogenation of acetylene in ethylene‐rich mixtures. Surface functionalization and structure modification of a series of bimetallic PdAg nanoparticles was performed using HHDMA as stabilizer and alloying the active palladium phase with silver. Bimetallic PdAg NPs with adjustable Pd/Ag ratio were prepared in water through a novel one‐pot methodology using hydrogen gas as a benign reducing agent and cyanide as additive. UV‐Vis studies indicated the formation of the bimetallic nanostructures through a sequential displacement‐galvanic reduction process mediated by cyanide. The series of colloidal NPs were deposited onto alumina and successfully applied as catalysts in the selective hydrogenation of acetylene in ethylene rich mixtures. Geometric and electronic promotion of Ag over Pd based catalysts was evidenced by the increase of the ethylene selectivity with the Ag content. The reactivity of these materials demonstrated the applicability of HHDMA stabilized NPs in a gas phase reaction of industrial interest and the success of combining several strategies for the enhancement of the alkene selectivity.
Wolbachia endobacteria depletion by doxycycline as antifilarial therapy has macrofilaricidal activity in onchocerciasis: a randomized placebo-controlled study (2007)

In a randomized, placebo-controlled trial in Ghana, 67 onchocerciasis patients received 200-mg/day doxycycline for 4-6 weeks, followed by ivermectin (IVM) after 6 months. After 6-27 months, efficacy was evaluated by onchocercoma histology, PCR and microfilariae determination. Administration of doxycycline resulted in endobacteria depletion and female worm sterilization. The 6-week treatment was macrofilaricidal, with >60% of the female worms found dead, despite the presence of new, Wolbachia-containing worms acquired after the administration of doxycycline. Doxycycline may be developed as second-line drug for onchocerciasis, to be administered in areas without transmission, in foci with IVM resistance and in areas with Loa co-infections.
Sequence analysis, tissue distribution and regulation by cell depolarization, and second messengers of bovine secretogranin II (chromogranin C) mRNA. (1990)

Secretogranin II is a very acidic, tyrosine-sulfated protein found in secretory granules of cells belonging to the diffuse neuroendocrine system. It gained more general importance recently as a universal immunohistochemical marker for endocrine neoplasms. Sequence information was obtained from secretogranin II isolated from bovine anterior pituitaries, allowing the isolation of cDNA clones and deduction of its primary structure. Bovine secretogranin II is a 586-amino acid protein of 67,455 Da which is preceded by a signal peptide of 27 residues and contains 9 pairs of basic amino acids in its sequence which are used as potential cleavage sites for generation of physiologically active peptides. Moderately abundant mRNA levels were found in adrenal medulla, pituitary, hippocampus, and caudate. Secretogranin II message was absent from parathyroid gland, adrenal cortex, kidney, liver, and spleen. Depolarization of isolated chromaffin cells by various secretagogues significantly up-regulated secretogranin II mRNA levels by mechanisms distinct from those established for chromogranins and neuropeptides, components maintained along with secretogranin II in neuroendocrine storage vesicles.
Spectrum splitting through CuS–ZnO/water hybrid nanofluid for agricultural greenhouse cooling applications: An experimental study (2023)

Abstract In the present work, CuS–ZnO/water hybrid nanofluids (in concentrations of 0.0025 mass% and 0.005 mass%) are synthesized using a two-step method with nanoparticles composition of 95% CuS and 5% ZnO. The optically tuned nanofluid filter on the agricultural greenhouse roof can reduce the cooling load by transmitting the visible spectrum and absorbing the near-infrared radiation in the solar spectrum. The size distribution of nanoparticles, stability and optical transmission of both concentrations in the visible and near-infrared regions are examined. Two hollow containers (i.e., ducts) with thicknesses of 4 mm and 8 mm are prepared. Each of these ducts is attached to a greenhouse unit and placed in front of a solar simulator. The experimental results reveal that applying CuS–ZnO nanofluid reduces the inside temperature of the greenhouse unit under all irradiance and ambient temperature ranges. The cooling system gains an average of 27.4% less heat from the greenhouse unit when the CuS–ZnO nanofluid flows through an 8 mm duct compared to no-fluid case (empty duct). The photothermal conversion efficiency of nanofluid is found to be higher than the one for water. The crop growth factor of 82.2% is obtained for 8 mm duct case, and the photosynthetic photon flux density inside the greenhouse unit is reduced without affecting the growth of many plants. Furthermore, the payback period of the nanofluid system (with 8 mm duct) is calculated as 0.42 years, and the application of optically tuned nanofluid can help reduce the cooling system's size and energy requirement for cooling.
Reliability and validity of the SKAMP rating scale in a laboratory school setting. (1998)

In children with attention deficit hyperactivity disorder (ADHD), the effects of methylphenidate were investigated in a pharmacodynamic comparison of placebo and the standard b.i.d. administration of methylphenidate. In each of these conditions, teachers completed ratings in classroom settings at times chosen to coincide with expected "peaks" and "troughs" of serum concentrations in the b.i.d. condition. Analyses of variance (ANOVAs) revealed the expected differences between the two conditions in the laboratory classroom setting using standard rating scales (Conners and the IOWA Conners) and a new rating scale (the SKAMP), which specifically measures the classroom manifestation of ADHD. The psychometric properties of the SKAMP were evaluated by calculating test-retest reliability and by calculating correlations with the standard rating scales to establish concurrent validity.
The Influence of Flow Domain Modeling on the Accuracy of Direct and Hybrid Aeroacoustic Noise Calculations (2006)

With the steadily growing computational power, Computational Fluid Dynamics (CFD) techniques become available for Computational Aero-Acoustics (CAA) purposes. Direct numerical simulations of the compressible Navier{Stokes equations (DNS) as well as Large Eddy simulations (LES) can be used to solve directly the acoustic fleld or can be used to compute equivalent aeroacoustic sources or acoustic information on a surface surrounding the main source region. These sources or acoustic surface-information are then propagated into the acoustic near- and far-fleld using appropriate propagation equations such as the linear acoustic wave equation, Linearized Euler Equations,. . . This paper discusses the aerodynamically generated noise by a ∞ow over a square cylinder at low Reynolds number (Re=200). The noise generating mechanism is quite well understood and the dominant Strouhal numbers can easily be predicted. For this reason this application is chosen for the current paper. DNS results are compared with difierent LES calculations, difiering from each other in the subgrid scale model, boundary conditions, number of elements and domain size. Both direct and hybrid methodologies are compared. The hybrid methodologies use difierent coupling methods and propagation equations. In this way, the paper provides an overview of the in∞uence of difierent ∞ow modeling techniques on a number of CAA-methodologies.
Bootstrapped Biocatalysis: Biofilm‐Derived Materials as Reversibly Functionalizable Multienzyme Surfaces (2017)

Cell-free biocatalysis systems offer many benefits for chemical manufacturing, but their widespread applicability is hindered by high costs associated with enzyme purification, modification, and immobilization on solid substrates, in addition to the cost of the material substrates themselves. Herein, we report a "bootstrapped" biocatalysis substrate material that is produced directly in bacterial culture and is derived from biofilm matrix proteins, which self-assemble into a nanofibrous mesh. We demonstrate that this material can simultaneously purify and immobilize multiple enzymes site specifically and directly from crude cell lysates by using a panel of genetically programmed, mutually orthogonal conjugation domains. We further demonstrate the utility of the technique in a bienzymatic stereoselective reduction coupled with a cofactor recycling scheme. The domains allow for several cycles of selective removal and replacement of enzymes under mild conditions to regenerate the catalyst system.
Set-based Cascading Approaches for Magnetic Resonance (MR) Image Segmentation (SCAMIS). (2006)

This paper introduces Set-based Cascading Approach for Medical Image Segmentation (SCAMIS), a new methodology for segmentation of medical imaging by integrating a number of algorithms. Existing approaches typically adopt the pipeline methodology. Although these methods provide promising results, the results generated are still susceptible to over-segmentation and leaking. In our methodology, we describe how set operations can be utilized to better overcome these problems. To evaluate the effectiveness of this approach, Magnetic Resonance Images taken from a teaching hospital research programme have been utilised, to reflect the real world quality needed for testing in patient datasets. A comparison between the pipeline and set-based methodology is also presented.
A learning-based hybrid approach for anonymous recommendation (2006)

In this paper we present a novel approach for anonymous recommendation that combines the knowledge-based recommendation with a learning component. The novelty of the approach is specially expressed through a new approach for cascade combination of two systems, that enables better the usage of prior knowledge in the learning process. Secondly, the training data for learning is based on a complex description of a recommendation situation, that enables significant improvement in the quality of recommendations in unseen situations. The approach has been implemented in a real e-commerce environment and tested in large dataset based on the twenty months usage data. The results of the evaluation studies show that this kind of hybrid systems is very promising for ephemeral recommendation.
Leave-one-out procedures for nonparametric error estimates (1989)

The use of nonparametric error estimates may lead to biased results if the kernel covariances are estimated from the same data as are used to form the error estimate. If additional design samples are available, one may eliminate this bias by estimating the class covariances using an independent set of data. If, however, additional samples are not available, one may resort to leave-one-out type estimates of the kernel (for Parzen estimates) or metric (for nearest-neighbor estimates) for every sample being tested. The authors present an efficient algorithm for computation of these leave-one-out type estimates that requires little additional computational burden over procedures currently in use. The presentation is applicable to both Parzen and k-nearest neighbor (k-NN) type estimates. Experimental results demonstrating the efficiency of the algorithm are provided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
헤롤드 J. 버만의 베버 사회학 연구를 비평함 (2015)

헤롤드 J 버만(1918-2007)은 법사학, 소비에트 및 러시아 법, 법의 본질과 그것의 기능, 법과 종교의 상호관계 등에 관심을 가진 법학자였다. 버만은 비교 역사학적 시각에서 법률, 종교, 경제 현상 등을 검토한 베버의 사회학적 연구에 주목했지만, 베버와 다른 시각에서 베버의 연구를 이해했다. 그래서 버만은 불행하게도 베버의 사회학 일반은 물론, 특히 베버의 법사회학을 심각하게 왜곡한 견해를 제시했다. 필자가 이 논문에서 추구하는 주요 목표는 버만이 부정확하게 곡해한 베버의 자본주의, 봉건주의, 도시, 법 등의 연구를 비판하는 것이다. 아울러 베버가 위 주제에 관해서 가졌던 본래의 생각을 최대한 정확하게 복원해내고자 한다. 끝으로 필자는 버만의 실수와 혼돈이 베버의 사회과학방법론을 제대로 이해하지 못한 데서 연유했다는 결론을 도출하고자 한다.
