Seed Lipoxygenase Products Modulate Aspergillus Mycotoxin Biosynthesis (1997)

Oilseed crops are frequently subject to contamination by mycotoxins produced by Aspergillus spp., particularly aflatoxin (AF) and to a lesser extent sterigmatocystin (ST). Several studies have suggested that metabolites generated from the plant lipoxygenase (LOX) pathway may either decrease or increase mycotoxin production by Aspergillus spp. We tested the possibility that the occurrence of seed LOX isozymes that produce distinct hydroperoxy fatty acids may account for these different effects on AF biosynthesis. For example, soybean LOX1 catalyzes the addition of O 2 to the C13 position of linoleic and linolenic acids while maize embryo LOX catalyzes the addition of O 2 to the C9 position. In vitro experiments showed that 13S-hydroperoxy fatty acids at concentrations of 10 and 100 μM repressed AF and ST pathway gene expression and significantly (P = 0.05) reduced AF and ST production in both A. parasiticus (AF producer) and A. nidulans (ST producer). Treatment with 1 μM 13S-hydroperoxy linoleic acid also significantly decreased AF production when introduced into growth media at continuous 24-h intervals. In contrast, the same concentrations of 9S-hydroperoxy linoleic acid did not reduce AF or ST production but extended the length of time AF and ST transcripts were detectable. These results show that 13S-hydroperoxy fatty acids directly or indirectly repress AF and ST biosynthesis and provide in vitro evidence that specific seed lipoxygenase activity could provide resistance to mycotoxin contamination by Aspergillus spp.
Non-destructive 3D shape measurement of transparent and black objects with thermal fringes (2016)

Fringe projection is a well-established optical method for the non-destructive contactless three-dimensional (3D) measurement of object surfaces. Typically, fringe sequences in the visible wavelength range (VIS) are projected onto the surfaces of objects to be measured and are observed by two cameras in a stereo vision setup. The reconstruction is done by finding corresponding pixels in both cameras followed by triangulation. Problems can occur if the properties of some materials disturb the measurements. If the objects are transparent, translucent, reflective, or strongly absorbing in the VIS range, the projected patterns cannot be recorded properly. To overcome these challenges, we present a new alternative approach in the infrared (IR) region of the electromagnetic spectrum. For this purpose, two long-wavelength infrared (LWIR) cameras (7.5 - 13 &mu;m) are used to detect the emitted heat radiation from surfaces which is induced by a pattern projection unit driven by a CO<sub>2</sub> laser (10.6 &mu;m). Thus, materials like glass or black objects, e.g. carbon fiber materials, can be measured non-destructively without the need of any additional paintings. We will demonstrate the basic principles of this heat pattern approach and show two types of 3D systems based on a freeform mirror and a GOBO wheel (GOes Before Optics) projector unit.
Minor and trace element distribution in the heavy minerals of the rivers and streams of the Bathurst-Jacquet River district, New Brunswick (1968)

This report describes the elemental distribution in heavy minerals collected from stream sediments in the Bathurst-Jacquet River district of New Brunswick. In a general way the variations of the elemental content of the heavy minerals reflects underlying bedrock and it appears that heavy mineral sampling in detail would be a useful way to conduct a reconnaissance geochemical survey for mineral deposits in the area.
Atomic layer deposition of high-kdielectrics on single-walled carbon nanotubes: a Raman study (2013)

Single-wall carbon nanotubes (SWCNTs) have great potential to become the channel material for future high-speed transistor technology. However, to realize a carbon nanotube field effect transistor (CNTFET) with excellent gate control, the high-k dielectrics between the CNT and the metal gate must have superb electrical properties and extremely high uniformity. Thus it is essential to understand the interactions between high-k materials and the SWCNTs to effectively control the transistor characteristics. In this study, we investigate the effects of atomic layer deposited (ALD) high-k dielectrics (Al2O3 and HfO2) on SWCNTs using Raman spectroscopy. We subjected the SWCNTs to various ALD cycles and studied the nucleation and growth of ALD dielectrics at defect sites using scanning electron microscopy and transmission electron microscopy images. We analyzed these samples using Raman spectroscopy and x-ray photoelectron spectroscopy. The Raman peak shifts of the G-peak and the 2D (G') peaks suggest doping and stress induced effects on the CNTs by the surrounding high-k oxide environment. Trends in the G-peak FWHM and G/D-peak ratios were identified and compared between Al2O3 and HfO2. We confirmed the ALD-deposited HfO2 is polycrystalline using x-ray diffraction and analyzed dielectric-CNT bonding states using XPS measurements. This study provides insights on the effects of ALD high-k materials on SWCNTs for future high-speed transistor applications.

Increased circulating CD11b+CD11c+ dendritic cells (DC) in aged BWF1 mice which can be matured by TNF-α into BLC/CXCL13-producing DC (2002)

Dendritic cells (DC) play a pivotal role in regulating immune responses. We previously reported aberrant high production of B lymphocyte chemoattractant (BLC/CXCL13) by DC in aged BWF1 mice, amurine model for systemic lupus erythematosus (SLE). We describe here that CD11b+CD11c+ cells were markedly increased in the peripheral blood (PBL-DC) in aged BWF1, but not in similarly aged NZB or NZW mice. Part of PBL-DC showed a typical dendritic morphology and expressed MHC class II molecules, and had a weak, but significant antigen-presenting ability in mixed lymphocytereaction. PBL-DC were chemoattracted to several chemokines in vitro including secondary lymphoid tissue chemokine (SLC), liver and activation-regulated chemokine (LARC), RANTES, macrophage inflammatory protein-1alpha, whereas splenic mature DC from aged BWF1 mice were preferentially chemoattracted towards SLC. BLC production was induced when PBL-DC were cultured in the presence of TNF-alpha for 3 days. BLC expression was also induced in bone marrow-derived DC when they were differentiated into mature DC in the presence of TNF-alpha and IL-1beta, while both IFN-alpha and IFN-gamma failed to induce BLC expression in bone marrow-derived DC. Since TNF-alpha expression is increased in aged BWF1 mice, DC recruitment in the circulation and maturation into BLC-producing DC by TNF-alpha may play a pivotal role in the development of systemic autoimmune diseases.
Miniaturized THz source with free-electron beams (2011)

The paper presents a novel miniaturized tunable, portable THz source for this frequency range using the Dynatron oscillator to control two miniaturized field emitter electron beam sources of high brightness, which emit charge pulses in each half wave's time to fly across a resonator, however through opposite apertures with opposite directions. The emitted infra-red dipole radiation is guided by a resonator and focused by lenses to the object. The output power at 0.2 THz to 10 THz is estimated do reach 0.5 W.
A Case of Infectious Crystalline Keratopathy Occurring Long After Penetrating Keratoplasty (1998)

This case is possibly the first to develop ICK long after PKP. Histologically, ICK presumably occurred based on the immunologically incompetent condition, and, by verifying the previous reports, the neurotrophic background after PKP may partially be involved in the development of ICK.

Part one: Patterns of health and disease among the Waorani Indians of Eastern Ecuador (1979)

Abstract The Waorani Indians, who live south of the Rio Napo in eastern Ecuador, are beginning to experience the effects of contact with the outside world. Synthesis of biomedical information with an understanding of cultural practices related to health provides insight into changing patterns of health and disease during the process of acculturation. The perspective gained from these multidisciplinary studies will aid in providing health care in the future and will increase appreciation of the ecology of health of these Amerindians in the past.
Reliability evaluation of direct chip attached silicon carbide pressure transducers (2006)

An accelerated stress test (AST) protocol has been developed and used to evaluate the reliability of 6H-silicon carbide (SiC) pressure transducers for operation up to 400 /spl deg/C for 100 hours. After several cyclic excursions to 400 /spl deg/C, the maximum drift of the zero pressure offset voltage at 25 /spl deg/C was 1.9 mV, while the maximum drift at 400 /spl deg/C was 2.0 mV. The full-scale sensitivity to pressure before and after the AST was 36.6 /spl mu/V/V/psi at 25 /spl deg/C and 20.5 /spl mu/V/V/psi at 400 /spl deg/C, with a maximum drift of /spl plusmn/1 /spl mu/V/V/psi. No systematic degradation of the zero pressure offset was observed.
The Extended Risk Assessment Form for IT/OT Convergence in IACS Security (2021)

Recently, security incidents that caused the shutdown or obstruction of the industrial automation and control systems (IACS) which support social infrastructure have increased rapidly. Many governments and businesses are addressing this urgent issue. IACS consists of two technologies, one is an information equipment based on information technology (IT) such as the Internet and cloud servers, and a control equipment based on operation technology (OT) such as controllers and sensing devices. The assets to be protected in IACS are not only IT information assets, as well as the functions and performance of OT related to human health and social services. For this reason, it has been known that the counter measures based on IT security alone are insufficient and incomplete. As an approach to this problem, IT/OT convergence has attracted attention in the IACS security problem. In order to bridge gaps of technical, human, and system gaps between IT and OT, new methodologies from the view of IT/OT convergence are being studied. This paper would discuss a security risk assessment for analyzing, designing counter measures and evaluating IACS security issues from the perspective of IT/OT convergence. Since the scope of assessment and the items to be examined will expand, we propose the extended risk assessment form that can take them into consideration. By using this form, it is possible to carry out security risk assessment covering IT and OT, safety and security, cyber and physical, as a series of sequences.
Measurement of charged particle multiplicities and densities in $$pp$$ p p collisions at $$\sqrt{s}=7\;$$ s = 7 TeV in the forward region (2014)

Charged particle multiplicities are studied in proton-proton collisions in the forward region at a centre-of-mass energy of [Formula: see text]TeV with data collected by the LHCb detector. The forward spectrometer allows access to a kinematic range of [Formula: see text] in pseudorapidity, momenta greater than [Formula: see text] and transverse momenta greater than [Formula: see text]. The measurements are performed using events with at least one charged particle in the kinematic acceptance. The results are presented as functions of pseudorapidity and transverse momentum and are compared to predictions from several Monte Carlo event generators.
Centrality dependence of charged hadron and strange hadron elliptic flow fromsNN=200GeV Au+Au collisions (2008)

We present STAR results on the elliptic flow ${v}_{2}$ of charged hadrons, strange and multistrange particles from $\sqrt{{s}_{\mathit{NN}}}=200$ GeV Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The detailed study of the centrality dependence of ${v}_{2}$ over a broad transverse momentum range is presented. Comparisons of different analysis methods are made in order to estimate systematic uncertainties. To discuss the nonflow effect, we have performed the first analysis of ${v}_{2}$ with the Lee-Yang zero method for ${K}_{S}^{0}$ and \ensuremath{\Lambda}. In the relatively low ${p}_{T}$ region, ${p}_{T}\ensuremath{\leqslant}2 \mathrm{GeV}/c$, a scaling with ${m}_{T}\ensuremath{-}m$ is observed for identified hadrons in each centrality bin studied. However, we do not observe ${v}_{2}({p}_{T})$ scaled by the participant eccentricity to be independent of centrality. At higher ${p}_{T},2\ensuremath{\leqslant}{p}_{T}\ensuremath{\leqslant}6 \mathrm{GeV}/c,{v}_{2}$ scales with quark number for all hadrons studied. For the multistrange hadron \ensuremath{\Omega}, which does not suffer appreciable hadronic interactions, the values of ${v}_{2}$ are consistent with both ${m}_{T}\ensuremath{-}m$ scaling at low ${p}_{T}$ and number-of-quark scaling at intermediate ${p}_{T}$. As a function of collision centrality, an increase of ${p}_{T}$-integrated ${v}_{2}$ scaled by the participant eccentricity has been observed, indicating a stronger collective flow in more central Au+Au collisions.
Diabetic Microvascular Disease: An Endocrine Society Scientific Statement (2017)

Both type 1 and type 2 diabetes adversely affect the microvasculature in multiple organs. Our understanding of the genesis of this injury and of potential interventions to prevent, limit, or reverse injury/dysfunction is continuously evolving. This statement reviews biochemical/cellular pathways involved in facilitating and abrogating microvascular injury. The statement summarizes the types of injury/dysfunction that occur in the three classical diabetes microvascular target tissues, the eye, the kidney, and the peripheral nervous system; the statement also reviews information on the effects of diabetes and insulin resistance on the microvasculature of skin, brain, adipose tissue, and cardiac and skeletal muscle. Despite extensive and intensive research, it is disappointing that microvascular complications of diabetes continue to compromise the quantity and quality of life for patients with diabetes. Hopefully, by understanding and building on current research findings, we will discover new approaches for prevention and treatment that will be effective for future generations.
Diabatic Dynamic Initialization (1993)

A generalized dynamical adjustment procedure has been applied to a diabatic model to produce balanced initial conditions. Namely, backward adiabatic model integration is followed by forward diabatic model integration, with a high-frequency (low-pass) filter in the form of the Euler backward time-differencing scheme being applied throughout the whole integration. As a result of the application of such a diabatic dynamic initialization procedure within the Goddard Laboratory for Atmospheres (GLA) 4D data-assimilation system, the following properties of forecasts from initialized fields are achieved right from the beginning of the usual forecast integration: 1) the forecast tendencies (and fields) are free of any noise due to imbalance in initial conditions, and 2) the shocks related to an initial imbalance between model physics and dynamics (and especially the substantial initial imbalance of precipitation and evaporation fields), or the initial spinup effect, are practically removed. Diabatic dynamic initialization has been compared with implicit nonlinear normal-mode initialization and found to be superior in removing the initial spinup effect and in improving the tropical structure. The diabatic dynamic initialization procedure has been successfully tested for the GLA system with the use of all conventional data and the GLA satellite data retrievals. It allows a smooth data insertion without any shocks or imbalances, which is highly desirable for efficient functioning of 4D data-assimilation systems. The developed initialization procedure is computationally efficient and in principle easily applicable to different large-scale and mesoscale forecast models.
Analysis of Multicomponent LPCVD Processes: Deposition of Pure and In Situ Doped Poly‐Si (1985)

A general model has been developed for multicomponent‐multireaction systems in the hot‐wall multiple‐wafers‐in‐tube LPCVD reactor. The modeling equations describe the coupled convective and diffusive mass fluxes in the annular reactor flow region as well as those between each pair of wafers. Complex reaction mechanisms involving both gas‐phase and surface reactions can be included in the model formulation. Multicomponent transport effects in the deposition of pure and doped polycrystalline Si are analyzed. The model predicts experimentally observed growth rates for pure polycrystalline Si quite well. However, because of insufficient data, a comparison of model predictions and experimental growth rates has not been feasible for in situ doped Si. The model is also used to predict the performance of a new continuous moving boat LPCVD reactor offering excellent film uniformity and process automation.
Drug delivery carriers on the fringes: natural red blood cells versus synthetic multilayered capsules (2012)

Red blood cells (RBC) and synthetic multilayered nanocarriers may appear as distant 'extremes' of the continuum of diverse drug delivery systems. The former are natural, old and simple, whereas the latter are artificial, novel and sophisticated. However, juxtaposition of features of these types of carriers, offered in a review article published in this issue, is instructive. Such an analysis helps to define both their distinctions and similarities (structural, functional, technological, specific areas of utility), and illustrates perspectives of their translation into the practice. Thus, synthetic multilayered carriers (which, in some embodiments, use elements of design inspired by RBC) represent an attractive research object offering high degree of control of their features. These carriers may find utility for intracellular delivery, controlled release of multiple cargoes and imaging. On the other hand, RBC provide arguably the most attractive carriers for sustained intravascular delivery of variety of drugs including biotherapeutics, either encapsulated into the inner RBC volume or coupled to RBC surface. The discussion of specific medical utility of these carriers and comparative analysis of the factors that may affect their translation (including complexity, costs, market value and therapeutic benefit/risk ratio) is timely and likely to intensify in the near future.
Effect of Local Damping in Perpendicular Recording Head: a Micromagnetic Study (2006)

This article reports the effect of varying the damping in different individual sections of the perpendicular recording head (like the yoke, pole and soft underlayer (SUL) regions) affects the head switching speed. Two head designs were used: the shielded head and monopole head design. The head model used in this paper divided the head into five regions: a) soft underlayer, b) tip, c) confluence, d) yoke, and e) shield. Results show that higher damping generally results in higher field amplitudes because the head field rise time is improved.

Astrocyte-Like Cells Derived From Human Oral Mucosa Stem Cells Provide Neuroprotection In Vitro and In Vivo (2014)

Human oral mucosa stem cells (hOMSC) are a recently described neural crest-derived stem cell population. Therapeutic quantities of potent hOMSC can be generated from small biopsies obtained by minimally invasive procedures. Our objective was to evaluate the potential of hOMSC to differentiate into astrocyte-like cells and provide peripheral neuroprotection. We induced hOMSC differentiation into cells showing an astrocyte-like morphology that expressed characteristic astrocyte markers as glial fibrillary acidic protein, S100β, and the excitatory amino acid transporter 1 and secreted neurotrophic factors (NTF) such as brain-derived neurotrophic factor, vascular endothelial growth factor, glial cell line-derived neurotrophic factor, and insulin-like growth factor 1. Conditioned medium of the induced cells rescued motor neurons from hypoxia or oxidative stress in vitro, suggesting a neuroprotective effect mediated by soluble factors. Given the neuronal support (NS) ability of the cells, the differentiated cells were termed hOMSC-NS. Rats subjected to sciatic nerve injury and transplanted with hOMSC-NS showed improved motor function after transplantation. At the graft site we found the transplanted cells, increased levels of NTF, and a significant preservation of functional neuromuscular junctions, as evidenced by colocalization of α-bungarotoxin and synaptophysin. Our findings show for the first time that hOMSC-NS generated from oral mucosa exhibit neuroprotective effects in vitro and in vivo and point to their future therapeutic use in neural disorders.
Multi-contrast scar CINE: sparsely sampled real-time inversion-recovery bSSFP CINE combined with iterative reconstruction and motion propagation (2015)

Background A new fast and robust technique combing CINE imaging with a retrospectively adjustable delayed-enhancement (DE) contrast in a short breath-hold of 4 seconds was recently introduced [1]. As a benefit of this technique, DE images can be reconstructed as a CINE series for any TI contrast, which in turn could be beneficial in the evaluation of CMR images and allow for improved diagnostic accuracy. In this work, we performed an initial clinical evaluation of the technique.
On a relaxation of SPR condition in parallel MRAS-continuous-time case (1988)

It is shown that the strict positive realness (SPR) condition for asymptotic stability of the continuous-time parallel model reference adaptive system (MRAS) can be removed provided that the parameter adaption law includes a proportional term and the information matrix is made sufficiently large. The present result a continuous-time counterpart of an earlier result (M. Tomizuka, ibid., vol.27, no.4, p.505-6, 1982) on the discrete-time parallel MRAS.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Coding Artifact Reduction using Non-Reference Block Grid Visibility Measure (2006)

In this work a new method is proposed for coding artifact reduction of MPEG compressed video sequences. The method makes use of a simple cost-effective technique that allows the block grid position and its visibility to be determined without the need for access to the coding parameters. This information, combined with the results of local spatial analysis of luminance and chrominance components of a decoded image, is used to effectively suppress coding artifacts while preserving the sharpness of object edges. Results of our experiments confirm the high efficiency of the proposed approach
