Explorations for real-time point cloud rendering of natural scenes in virtual reality (2016)

This work is a proof of concept, where we explore the possibility of rendering natural scenes in a head mounted display device without meshing. Real-time, stereoscopic full-HD rendering is obtained for a 14 million points scene, using a low end graphics card for virtual reality (Nvidia GeForce GTX 970), within an Oculus Rift DK2. High quality is achieved by using splatting, while real-time rendering is made possible by the means of a good data structure and a complexity reduction of the scene with techniques such as Optimized Sub-Sampling, Level of Detail and Frustum Culling. Altogether, those techniques lead to a good virtual reality immersion. Choices and limitations of the proposed techniques are discussed.
Purification and characterization of a 1,2,4-trihydroxybenzene 1,2-dioxygenase from the basidiomycete Phanerochaete chrysosporium (1994)

1,2,4-Trihydroxybenzene (THB) is an intermediate in the Phanerochaete chrysosporium degradation of vanillate and aromatic pollutants. A P. chrysosporium intracellular enzyme able to oxidatively cleave the aromatic ring of THB was purified by ammonium sulfate precipitation, hydrophobic and ion-exchange chromatographies, and native gel electrophoresis. The native protein has a molecular mass of 90 kDa and a subunit mass of 45 kDa. The enzyme catalyzes an intradiol cleavage of the substrate aromatic ring to produce maleylacetate. 18O2 incorporation studies demonstrate that molecular oxygen is a cosubstrate in the reaction. The enzyme exhibits high substrate specificity for THB; however, catechol cleavage occurs at approximately 20% of the optimal rate. THB dioxygenase catalyzes a key step in the degradation pathway of vanillate, an intermediate in lignin degradation. Maleylacetate, the product of THB cleavage, is reduced to beta-ketoadipate by an NADPH-requiring enzyme present in partially purified extracts.

Si nanocrystal MOSFET with silicon nitride tunnel insulator for high-rate random number generation (2006)

It is shown that sub-0.1 μm Si nanocrystal bulk MOSFET with thin SiN tunnel insulator is a very strong random noise source used in high-rate small-size random number generation circuit, which is required for cryptograph application in mobile network security. A fast random number generation rate of 0.12 MHz is demonstrated using Si nanocrystal MOSFET and a simple small circuit. It is suggested that a small-size random number generator with MHz generation rate, which is applicable for almost all security uses in our computer society, is possible by Si nanocrystal MOSFET device design.
Electricity basics - Technical Issues of Production and Utilization (2003)

This article is the third in A series based on the IEEE PES Power System Basics for Business Professionals tutorial. Perhaps the most difficult part of presenting power system basics is the need to introduce fundamental laws, complex phenomena, and the associated terminology and jargon. It requires a delicate balance between being true to the physical world and being understandable by business professionals. This article summarizes that delicate balance and gives the essence of the tutorial presentations made on the subject of "Introduction to Electricity and the Technical Issues of Its Production and Use".
Identification of the Floral Origin of Honey by Amino Acids Composition (2010)

A study was performed to find a correlation criterion between the amino acid composition and the botanical origin, in order to classify honey. The amino acids analyzer was used to determine the amino acids of honey samples from five different single botanical origins. Aspartic acid, phenylalanine, glutamic acid and proline were predominant ones, but not unique for honey types. Cystine was not detected in Acacias and Azadirachta honey. For all honey types the reset of amino acids determined, differed among them. Principle component analysis (PCA) was applied to data for pattern recognition. Discriminant function analysis was applied to four selected amino acids (Asp, Glu, His, and Phe) based on the result of PCA. Five groups of honey are shown in Dendrogram using cluster analysis. Discriminant function analysis showed high correct classification rate (93.33%). Ziziphus, Helianthus, Acacia seyal and Azadirachta honeys were 100% correctly classified and Acacia nilotica honey was 66.67% correctly classified.
Visible Surface Algorithms for Quadric Patches (1972)

This paper describes two algorithms which find the visible portions of surfaces in a picture of a cluster of three-dimensional quadric patches. A quadric patch is a portion of quadric surface defined by a quadratic equation and by zero, one, or several quadratic inequalities. The picture is cut by parallel planes called scan planes. The visibility problem is solved in one scan plane at a time by making a "good guess" as to what is visible according to the visible portions found in the previous scan plane.
Application of AZARASHI (seal) positioning mechanism to micromanipulation by vacuum suction (2009)

This paper deals with an application of a small mobile device, ldquoAZARASHI (seal) Mechanismrdquo with three degrees of freedom (DOFs) to a micromanipulation device. AZARASHI mechanism has a smaller number of controlled devices than the inchworm-like device. The small device with multiple DOFs can be built by combining such mechanism. A micromanipulation device consists of an L-shaped device for the x-, y- and thetas-motions, and one-DOF device in the z-motion. By the visual feedback, a glass bead is placed automatically. In order to trap a glass bead with a diameter of 60-70 mum, the air was gently sucked through the glass capillary. Then the bead is trapped and placed after moving the stage. Finally, the bead is placed. The performance of the manipulation device was measured. Positioning accuracy of the stage was within 1 pixel. However, a process of the bead release often disturbed the total accuracy.
Intraoperative Heat Conservation Using a Reflective Blanket (1984)

brated with ambient temperature. Test patients were wrapped in the aluminized blanket as completely as po­ sitioning would allow; test and control patients were draped in standard manner. For test patients in Groups 1 and 2, a copper cable connected the aluminized blanket to the operating table to prevent patient isolation. Patient temperature, mon­ itored with an esophageal temperature probe,20 operating room temperature, and relative humidity were recorded at half-hour intervals. Other aspects of anesthetic man­ agement were left to the discretion of the responsible anesthesiologist. Patients were observed for shivering in the recovery room by a nurse blinded to the treatment. Observations were subjected to chi-square analysis. Tem­ perature and humidity data were examined by analysis of variance. All results are reported as significant if P < 0.05.
Diagnosis Methods for Electronic Controlled Vehicles (2001)

Abstract The development of automotive systems shows an increasing number of sensors, actuators and microelectronic controllers, partially for active driver assistance. However, electronic and electrical components have quite different failure behavior and in general lower reliability than mechanical components. On the other side microcomputers can also be used for fault detection and diagnosis. The contribution therefore shows how model-based fault detection and diagnosis methods together with few available measurements can be applied for automobiles. After an introduction, a short summary is given for fault detection and diagnosis methods, especially for model-based methods. Then some research results are shown, like the fault detection and diagnosis of an electromechanical throttle actuator, a suspension system and the lateral behavior of a passenger car. Finally, methods for fault-tolerant sensors and actuators are discussed which are required for drive-by-wire systems.
An 11-mer Amyloid Beta Peptide Fragment Provokes Chemical Mutations and Parkinsonian Biomarker Aggregation in Dopaminergic Cells: A Novel Road Map for “Transfected” Parkinson’s (2016)

Amyloid beta (Aβ) aggregation is generally associated with Alzheimer's onset. Here, we demonstrate that incubation of dopaminergic SH-SY5Y cells with an Aβ peptide fragment (an 11-mer composed of residues 25-35; Aβ (25-35)) results in elevated intracellular nitrosative stress and induces chemical mutation of protein disulfide isomerase (PDI), an endoplasmic reticulum-resident oxidoreductase chaperone. Furthermore, Aβ (25-35) provokes aggregation of both the minor and major biomarkers of Parkinson's disease, namely, synphilin-1 and α-synuclein, respectively. Importantly, fluorescence studies demonstrate that Aβ (25-35) triggers colocalization of these Parkinsonian biomarkers to form Lewy-body-like aggregates, a key and irreversible milestone in the neurometabolic cascade leading to Parkinson's disease. In addition, fluorescence assays also reveal direct, aggregation-seeding interactions between Aβ (25-35), PDI and α-synuclein, suggesting neuronal pathogenesis occurs via prion-type cross-transfectivity. These data indicate that the introduction of an Alzheimer's-associated biomarker in dopaminergic cells is proliferative, with the percolative effect exercised via dual, independent, Parkinson-pathogenic pathways, one stress-derived and the other prion-like. The results define a novel molecular roadmap for Parkinsonian transfectivity via an Alzheimeric burden and reveal the involvement of PDI in amyloid beta induced Parkinson's.
Oral Rehydration Therapy in the Second Decade of the Twenty-first Century (2014)

Oral rehydration solution (ORS) was established as the cornerstone of therapy for dehydration secondary to acute infectious diarrhea approximately 40 years ago. The efficacy of ORS is based on the ability of glucose to stimulate Na and fluid absorption in the small intestine via a cyclic AMP-independent process. Despite the establishment that ORS is the primary reason for the substantial reduction in morbidity and mortality from diarrhea in children in developing countries, the use of ORS has lagged for many reasons. This review highlights efforts to establish a major reformulation of ORS following the demonstration that short-chain fatty acids (SCFA) stimulate colonic Na and fluid absorption by a cyclic AMP-independent mechanism. The addition of high-amylose maize starch (HAMS), a microbially-fermentable (or 'resistant') starch, to ORS results in delivery of non-absorbed carbohydrate to the colon where it is fermented to SCFA. To date, three randomized controlled trials with a HAMS-ORS in south India have demonstrated a substantial decrease in diarrhea duration in both adults and children hospitalized for acute diarrhea. Significant efforts are now underway to establish this dual-action, modified HAMS-hypoosmolar ORS solution as the standard ORS for the treatment of dehydration from acute diarrhea.

A Technique for the Effective Removal of Air from a Hollow Fiber Membrane Oxygenator Circuit (1986)

This paper describes some of the ways unwanted air can be introduced into a cardiopulmonary bypass circuit and a technique which has been shown to significantly decrease the resultant bubble counts. In this study air was introduced into a circuit (Hct. 20%) containing a Hollow Fiber Membrane Oxygenator (HFMO). Conventional techniques of recirculation (3 L/min.) and vigorous agitation/percussion were compared to recirculation with vacuum (gas phase of HFMO) for efficiency in reducing bubble counts measured after three minutes by a microbubble counter. Conventional methods were ineffective after three minutes while vacuum for 3 minutes significantly (p = .001) reduced bubble counts (bubbles > 100 microns). The microporous membrane allows efficient air removal with vacuum while recirculation/percussion did little to remove air which, in a blood perfusate, was not visible to the naked eye. The application of vacuum not only increases safety but convenience when used in the priming and de bubbling of a circuit in routine and emergency case.
Emergence of plasmid stability under non-selective conditions maintains antibiotic resistance (2019)

Plasmid acquisition is an important mechanism of rapid adaptation and niche expansion in prokaryotes. Positive selection for plasmid-coded functions is a major driver of plasmid evolution, while plasmids that do not confer a selective advantage are considered costly and expected to go extinct. Yet, plasmids are ubiquitous in nature, and their persistence remains an evolutionary paradox. Here, we demonstrate that non-mobile plasmids persist over evolutionary timescales without selection for the plasmid function. Evolving a minimal plasmid encoding for antibiotics resistance in Escherichia coli, we discover that plasmid stability emerges in the absence of antibiotics and that plasmid loss is determined by transcription-replication conflicts. We further find that environmental conditions modulate these conflicts and plasmid persistence. Silencing the transcription of the resistance gene results in stable plasmids that become fixed in the population. Evolution of plasmid stability under non-selective conditions provides an evolutionary explanation for the ubiquity of plasmids in nature.
Detection ofS-Nitrosothiols and Other Nitric Oxide Derivatives by Photolysis–Chemiluminescence Spectrometry (1997)

We have developed a method for the detection of biologically relevant derivatives of NO. that couples photolysis to chemiluminescence. S-Nitrosothiols, N-nitroso-L-tryptophan, and iron-nitrosyl derivatives can all be detected by this methodology, and these derivatives can be distinguished from free NO. by making measurements with and without photolysis. The limits of detection of this system are in the 10 nM range, with an intraassay variability of less than 2% and an interassay variability of less than 1.5%. The use of cutoff filters and alterations in pH and flow rate through the photolysis cell provide additional useful parameters with which to characterize specific NO. derivatives based on their intrinsic stability. This methodology is a useful addition to the growing armamentarium of techniques used to characterize the biochemistry and metabolism of NO..
骨格筋再生過程におけるミオシン重鎖 アイソフォームとmyogenin・MyoD発現について (2002)

骨格筋再生過程におけるミオシン重鎖(MHC)アイソフォーム発現とmyogenin，MyoDタンパクの発現様式との関連性を検討するために，塩酸ブピバカインを用いてマウスヒラメ筋損傷モデルを作成し，損傷筋の再生過程を組織形態学的に確認すると同時に，再生各段階におけるMHCアイソフォームと，myogeninおよびMyoDタンパク発現を経時的に検索した．本研究における筋損傷は塩酸ブピバカインをマウス(C57BL/10SnSlc)のヒラメ筋に注入することで作成した．組織学的には，塩酸ブピバカイン投与後3日目で筋線維はほとんど消失し，処置後6日目で中心核を有する再生筋線維がかなり出現し，処置後28日目では対照群のものと同程度まで回復した．生化学的分析では，対照群ヒラメ筋はMHCⅠ(34．3±1．7%)とMHCⅡa(65．7±1．7%)で構成されていた．実験群ヒラメ筋ではMHCⅠは処置後14日目まで減少し，その後増加傾向を示し，処置後90日目では36．3±2．9%となった．また，正常ヒラメ筋では検出されない速筋型MHC(MHC Ⅱd，MHC Ⅱb)が処置後3日目から28日目まで検出された．Western blotを用いた分析では，myogeninタンパク正常ヒラメ筋（遅筋）で検出された一方，前脛骨筋（速筋）においては検出できなかった．実験群ヒラメ筋では，myogeninは対照群と比較して処置後３日目より増加し（3．1±0．5），処置後６日目でピークに達した（5．8±0．8）．それからmyogeninタンパクは徐々に減少していったが，処置後90日目においてもなお対照群ヒラメ筋の1．8倍の発現を維持し続けた．一方，MyoDタンパクは正常前脛骨筋において正常ヒラメ筋の3．3倍の発現が認められた．MyoDは処置後３日目で対照群ヒラメ筋と比較して5．4倍になりピークに達した．その後は徐々に減少し始めた．しかし処置後90日目においても2．2倍の発現があった．これらのことから筋の再生過程においては速筋タイプの筋細胞が出現するmyogeninとMyoDは衛星細胞の分化と筋の再生に密接に関係していることが示唆された．

The Origins of the Urartians in the light of the Van/Karagündüz excavations (1999)

The Urartian Kingdom, as is well known, played a major power role on the stage of history in eastern Anatolia in the second half of the ninth century BC and remained powerful until the second half of the seventh century BC. With their highly advanced architectural traditions and organised state structure, the Urartians take their place among the most exciting civilisations of the first half of the first millennium BC in the Near East. Extensive detailed research and publication has been carried out on Urartian civilisation for over a hundred years, but the origin and dynamics of the development of this civilisation are still obscure. The Assyrian annals, which start from the 13th century BC, are at present the only source for understanding the early periods. These records were intended as propaganda and their accuracy is in many instances thus questionable.
Radiation effects on microelectronics in space (1988)

The basic mechanisms of space radiation effects on microelectronics are reviewed. Topics discussed include the effects of displacement damage and ionizing radiation on devices and circuits, single-event phenomena, dose enhancement, radiation effects on optoelectronic devices and passive components, hardening approaches, and simulation of the space radiation environment. A summary of damage mechanisms that can cause temporary or permanent failure of devices and circuits operating in space is presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Emodin suppresses lipopolysaccharide‐induced pro‐inflammatory responses and NF‐κB activation by disrupting lipid rafts in CD14‐negative endothelial cells (2010)

Lipid rafts were crucial in facilitating inflammatory responses of mCD14-negative HUVECs to LPS. Emodin disrupted lipid rafts through depleting cholesterol and, consequently, inhibited inflammatory responses in endothelial cells.
Normal phosphorylation of duck hepatitis B virus L protein is dispensable for infectivity. (1998)

A fraction of the large surface protein (L) of duck hepatitis B virus (DHBV) is phosphorylated at serine or threonine residues (E. Grgacic & D. Anderson, Journal of Virology 68, 7344-7350, 1994). We now report the identification of phosphorylation sites in DHBV L protein. Using site-directed mutagenesis, we have identified serine-118 (S118) as the major phosphorylation site, accepting approximately 64% of the total phosphate groups incorporated in L, and resulting in retarded migration of phosphorylated L in SDS-PAGE. Proline-119 is indispensable for S118 phosphorylation. Mutation of other serine/threonine residues which are followed by prolines (T79, T89, S117 and T155) together with S118 further reduced phosphorylation to around 19% of wild-type. Non-equilibrium pH gel electrophoresis (NEPHGE) and SDS-PAGE of 33P-labelled L protein revealed two phosphorylated L species, while protein with the S118 to alanine mutation was detected as only one labelled species, consistent with multiple phosphorylations in wild-type L. Together, these results demonstrate that serine 118 is the major phosphorylation site for a proline-directed kinase, and that a proportion of L molecules are additionally phosphorylated at one of a number of secondary sites. DHBV mutants encoding L proteins with minimal phosphorylation (alanine mutants) or mimicking constitutive phosphorylation (aspartic acid mutants) remained infectious both in cell culture and in ducks, demonstrating that L phosphorylation may play only a minor role in DHBV replication.
Lossless Compression Algorithms for Post-OPC IC Layout (2007)

An important step in today's integrated circuit (IC) manufacturing is optical proximity correction (OPC). While OPC increases the fidelity of pattern transfer to the wafer, it also results in significant increase in IC layout file size. In this paper, we develop two techniques for compressing post-OPC layout data while remaining compliant with existing industry standard data formats such as OASIS and GDSII. The motivation for doing so is for the resulting compressed files to be viewed and edited by any industry standard CAD tools without a decoder. Our approach is to eliminate redundancies in the representation of the geometric data by finding repeating groups of polygons between multiple cells as well as within a cell. We refer to the former as "inter-cell sub-cell detection" and the later as "intra-cell sub-cell detection". Both problems are NP hard, and as such, we propose two sets of greedy algorithms to solve them. We show the results of our proposed inter-cell and intra-cell algorithms on actual 90nm, 130nm, and 180nm IC layouts.
A Cloud Monitoring System for Remote Sites (1998)

Abstract A cloud monitor has been developed for use with cosmic ray air shower fluorescence detectors, the High Resolution Fly's Eye and the Pierre Auger Observatory. This is based on an infrared thermopile device which, unlike previous such monitors, requires no moving chopper and is suitable for unattended operation over long periods of time.
Bacteriology, Drug Stability and Exchange of Percutaneous Delivery Systems and Antibacterial Filters in Long-Term Intrathecal Infusion of Opioid Drugs and Bupivacaine in “Refractory” Pain (1992)

In our population, exchange of the infusion systems when they are empty (within 1 month) and of the antibacterial filters once a month does not appear to affect the concentrations of, or increase the infection risk from, the opioid-bupivacaine mixtures. The risk of bacterial contamination/colonization of the syringes from syringe drivers does not seem to be higher than that of cassettes from external portable pumps.
