A New Narrow Band Frequency Selective Surface Geometry Design at the Unlicensed 2.4‐GHz ISM Band (2013)

ABSTRACT Wireless devices in the unlicensed instruments, scientific, and measurements (ISM) bands cause mutual interference in indoor environments. This interference degrades the system performance and compromises security. Transforming existing building walls to a band stop frequency selective surface (FSS) can be an efficient solution for such problems. This work is proposed to design FSS for interference mitigation and network security within the buildings in the unlicensed 2.4‐GHz ISM band and to provide maximum transparency at broadcast frequencies. A 2.4‐GHz ISM band is a relatively narrow band which cannot be met by a conventional FSS for a wide range of incidence angle. Whereas wireless signals in indoor environment have a wide range of incidence angle. To obtain the desired narrow band response, a new FSSs element geometry is introduced which has a stable frequency response for TE polarization when the angle of incident wave is varied from 0° to 70°. HFSS software is used for simulation and design purposes. The obtained simulation and measurement results show that desired frequency response is achieved for TE polarization successfully. © 2013 Wiley Periodicals, Inc.

A 5G-V2X Based Collaborative Motion Planning for Autonomous Industrial Vehicles at Road Intersections (2018)

Self-driving and connected vehicles, communicating with one another and with the road infrastructure are expected to revolutionize the automotive industry and our life in the future. We propose a distributed heuristic algorithm based on 5G-V2X technology to solve the motion planning problem of industrial vehicles, especially passing through intersections in industrial parks. Autonomous industrial vehicles must not only ensure that vehicles do not collide with each other through intersections, but also ensure the safety of pedestrians. So this case demands highly on the communication and mutual cooperation among vehicles. To solve this problem, we employ 5G-V2X technology to ensure low delay and highly reliable communications. Then, we propose a distributed heuristic algorithm to solve the mutual cooperation problem among vehicles. Specifically speaking, intersection safety information system will download LDM (Local Dynamic Map) information to vehicle closest to the intersection, and then our solution will give higher priority to paths that have more vehicles and no pedestrians. Starting with highest priority approach, our solution sets a time period for the vehicle to establish a timetable for it to cross the intersection. Preliminary experiments results showed that on the premise of ensuring the safety of pedestrians, the industrial vehicles can pass through the intersection smoothly and have the lowest delay at the same time.

The Electron Transfer System of Syntrophically Grown Desulfovibrio vulgaris (2009)

Interspecies hydrogen transfer between organisms producing and consuming hydrogen promotes the decomposition of organic matter in most anoxic environments. Although syntrophic coupling between hydrogen producers and consumers is a major feature of the carbon cycle, mechanisms for energy recovery at the extremely low free energies of reactions typical of these anaerobic communities have not been established. In this study, comparative transcriptional analysis of a model sulfate-reducing microbe, Desulfovibrio vulgaris Hildenborough, suggested the use of alternative electron transfer systems dependent on growth modality. During syntrophic growth on lactate with a hydrogenotrophic methanogen, numerous genes involved in electron transfer and energy generation were upregulated in D. vulgaris compared with their expression in sulfate-limited monocultures. In particular, genes coding for the putative membrane-bound Coo hydrogenase, two periplasmic hydrogenases (Hyd and Hyn), and the well-characterized high-molecular-weight cytochrome (Hmc) were among the most highly expressed and upregulated genes. Additionally, a predicted operon containing genes involved in lactate transport and oxidation exhibited upregulation, further suggesting an alternative pathway for electrons derived from lactate oxidation during syntrophic growth. Mutations in a subset of genes coding for Coo, Hmc, Hyd, and Hyn impaired or severely limited syntrophic growth but had little effect on growth via sulfate respiration. These results demonstrate that syntrophic growth and sulfate respiration use largely independent energy generation pathways and imply that to understand microbial processes that sustain nutrient cycling, lifestyles not captured in pure culture must be considered.
Expression of Reg IV and Hath1 in neuroendocrine neoplasms. (2010)

Reg IV (RELP), a Regenerating protein family member, is constitutively expressed in neuroendocrine cells of the intestinal mucosa. The helix-loop-helix transcription factor Hath1 is the human homologue of murine Math1, which regulates the embryonic differentiation of neural and intestinal secretory lineage cells. Hath1 is constitutively expressed in a subset of mature secretory gastrointestinal cells. We investigated by immunohistochemistry the expression of Reg IV and Hath1 in 63 neuroendocrine tumors. Intestinal neuroendocrine neoplasms showed co-expression of Reg IV and Hath1, as did parathyroidal and Merkel cell tumors. Lung small-cell carcinoma and gastric mucocellular carcinoma expressed only Reg IV. Pancreatic islet-derived tumors, pheochromocytomas, and paragangliomas expressed only Hath1. Lymph node and liver metastases retained the tissue-specific expression patterns. These distinct expression profiles may be useful for differential diagnostics of metastatic lesions of neuroendocrine tumors. The dissimilar expression patterns suggest that the proteins belong to different signaling pathways and are activated at different stages of neuroendocrine differentiation. Local Reg IV expression may be influenced by the growth factors bFGF and HGF and/or their receptors CD138 and c-met, which were found to co-localize with Reg IV in intestinal neuroendocrine tumors.
Bacteriocin Production with Lactobacillus amylovorus DCE 471 Is Improved and Stabilized by Fed-Batch Fermentation (2000)

Amylovorin L471 is a small, heat-stable, and hydrophobic bacteriocin produced by Lactobacillus amylovorus DCE 471. The nutritional requirements for amylovorin L471 production were studied with fed-batch fermentations. A twofold increase in bacteriocin titer was obtained when substrate addition was controlled by the acidification rate of the culture, compared with the titers reached with constant substrate addition or pH-controlled batch cultures carried out under the same conditions. An interesting feature of fed-batch cultures observed under certain culture conditions (constant feed rate) is the apparent stabilization of bacteriocin activity after obtaining maximum production. Finally, a mathematical model was set up to simulate cell growth, glucose and complex nitrogen source consumption, and lactic acid and bacteriocin production kinetics. The model showed that bacterial growth was dependent on both the energy and the complex nitrogen source. Bacteriocin production was growth associated, with a simultaneous bacteriocin adsorption on the producer cells dependent on the lactic acid accumulated and hence the viability of the cells. Both bacteriocin production and adsorption were inhibited by high concentrations of the complex nitrogen source.
A Genome-Wide Association Study of Myasthenia Gravis (2020)

Myasthenia gravis is a chronic, autoimmune, neuromuscular disease characterized by fluctuating weakness of voluntary muscle groups. Although genetic factors are known to play a role in this neuroimmunological condition, the genetic etiology underlying myasthenia gravis is not well understood.
Turbulent cascade in fully developed turbulent channel flow (2023)

We show that Kolmogorov scale-by-scale equilibrium in the intermediate layer of a fully developed turbulent channel flow is only achieved asymptotically around the Taylor length and, therefore, not in an inertial range. Furthermore, we analyse scale-by-scale turbulence production and interscale turbulence energy transfer in terms of alignments/anti-alignments of fluctuating velocities, straining/compressive relative motions, forward/inverse interscale transfer/cascade and homogeneous/non-homogeneous interscale transfer rate contributions. We also propose leading order scalings for second- and third-order two-point statistics, including the extremum interscale turbulence energy transfer rate and a second-order anisotropic structure function, which acts as a scale-by-scale Reynolds shear stress and determines the scale-by-scale (two-point) turbulence production rate.
HARDWARE COMMISSIONING OF THE RIKEN SUPERCONDUCTING RING CYCLOTRON (2007)

Since 1997, RIKEN Nishina Center has been constructing the Radioactive Isotope Beam Factory (RIBF) and succeeded in beam commissioning of its accelerator complex at the end of 2006 [1,2]. The world’s first superconducting ring cyclotron (SRC) is the final booster in the RIBF accelerator complex. Assembling of its superconducting sector magnets was completed in August 2005. The superconducting coils were successfully cooled down and excited for tests from the various points of view: magnetic force, coil protection and quality of magnetic field, showing that they work as designed. After a series of the test the other components than the sector magnets were installed and tested under stray fields from the sector magnets. After setups of beam vacuum and radio frequency, beam commissioning started. The first beam was extracted at the end of 2006 and the first uranium beam was extracted in March 2007.

Hsp90 Phosphorylation Is Linked to Its Chaperoning Function (2001)

Studies on Hsp90 have mainly focused on its involvement in the activation of several families of protein kinases and of steroid hormone receptors. Little is known regarding the role of Hsp90 in the folding of nascent proteins. We previously reported that Hsp90 plays an active role in the posttranslational assembly of the C-terminal globular head of the reovirus attachment protein final sigma1. We show here that Hsp90 becomes phosphorylated in this process. However, only the unphosphorylated form of Hsp90 is complexed with final sigma1, suggesting that Hsp90 phosphorylation is coupled to the release of the chaperone from the target protein. Geldanamycin, which blocks final sigma1 maturation by preventing the release of Hsp90 from final sigma1, also inhibits Hsp90 phosphorylation. Taken together, these results demonstrate that Hsp90 phosphorylation is linked to its chaperoning function.
Three-dimensional simulation of free-electron laser harmonics with Fred (2005)

FRED3D, a single-mode three-dimensional version of the free-electron laser (FEL) simulation code FRED, is being modified to follow the growth of signal components at the fundamental frequency and at even and odd harmonics. The wiggle-averaged particle and field equations for this multimode formulation are derived here, and their implementation in FRED3D is discussed.
[Food and cancer: state of the art about the protective effect of fruits and vegetables]. (2002)

Epidemiological studies performed during the last 20 years support an inverse relationship between the individual intake of fruits and vegetables and the risk of cancer. In taking into account some recent conflicting data, a working group of the Nacre network, the French Network for Food and Cancer Research, has conduced a critical analysis of epidemiological and experimental studies, including the preliminary data from the Epic cohort, the European Prospective Investigation into Cancer and Nutrition, to clarify the role of fruits and vegetables to prevent cancer. To date, a high intake of fruits and vegetables (at least, 400 g per day) is appropriate to lower the risk of cancer. Fruits and vegetables provide numerous phytochemicals which, in part, may explain their beneficial effect. Thus, studies in animal models and in cell-culture systems have furnished a lot of information about the potential mechanism by which a diet high in fruits and vegetables may reduce the risk of cancer in humans. However, more investigation in the identification of the biologically active constituents, in the knowledge of their availability and the mechanism by which they contribute to lower the risk of cancer, will increase the scientific support of a public health policy.
Building Blocks for the Preparation of Enantiomerically Pure Drugs Containing a Phenylalkylamine Moiety. Synthesebausteine zur Herstellung enantiomerenreiner Arzneistoffe mit Phenylalkylamin‐Partialstruktur (1994)

Abstract The enantiomers of chiral drugs may exhibit distinctly different pharmacokinetic and pharmacodynamic properties. Thus, the application of pure enantiomers is desirable in most cases. Therefore, it is necessary to know which enantiomer is the more advantageous one and to work out an economical large scale synthesis of this pure enantiomer. Biocatalytic transformations of prochiral compounds provide an easy and efficient access to chiral, non racemic compounds. Therefore, we fixed upon microbial reductions of carbonyl compounds as the key steps in the preparation of enantiomerically pure building blocks.
Staphylococcus aureus Infection of the Optic Nerve (2014)

A 71-year-old woman presented with painful vision loss in the right eye followed by ophthalmoplegia. Magnetic resonance imaging demonstrated optic nerve sheath enlargement and enhancement. Biopsy of the optic nerve sheath revealed purulent and necrotic material that was positive for methicillin-sensitive Staphylococcus aureus. The patient underwent enucleation of the right eye and was treated with systemic antibiotics with clinical stabilization. Imaging, pathological and treatment aspects of optic nerve sheath abscess are discussed.
[Quantitative evaluation of corneal epithelial barrier function in corneal epithelial edema]. (1995)

Corneal epithelial barrier function in patients with corneal epithelial edema was evaluated by fluorophotometry. Fluorescein uptake through the intact corneal epithelium was 28.1 +/- 2.7 ng/ml (n = 35, mean +/- SE (standard error), calculated from the standard line) at 30 minutes after instillation of 3 microliters of 0.5% sodium fluorescein (20 minutes after eye washing with 20 ml of BSS PLUS). Fluorescein uptake by the cornea in 7 patients with corneal epithelial edema and 6 patients with corneal stromal edema without epithelial edema were 2,489.7 +/- 1,045.6 ng/ml and 99.3 +/- 25.0 ng/ml, respectively, showing a significant increase when compared to normal corneal epithelium (p < 0.0005). Moreover, in patients with corneal epithelial edema, the corneal epithelial barrier function showed significant decrease in comparison with those having corneal stromal edema without epithelial edema (p < 0.05). These results demonstrate a significant decrease in the corneal epithelial barrier function in the epithelial edema.
Longitudinal Antigenic Sequences and Sites from Intra-Host Evolution (LASSIE) Identifies Immune-Selected HIV Variants (2015)

Within-host genetic sequencing from samples collected over time provides a dynamic view of how viruses evade host immunity. Immune-driven mutations might stimulate neutralization breadth by selecting antibodies adapted to cycles of immune escape that generate within-subject epitope diversity. Comprehensive identification of immune-escape mutations is experimentally and computationally challenging. With current technology, many more viral sequences can readily be obtained than can be tested for binding and neutralization, making down-selection necessary. Typically, this is done manually, by picking variants that represent different time-points and branches on a phylogenetic tree. Such strategies are likely to miss many relevant mutations and combinations of mutations, and to be redundant for other mutations. Longitudinal Antigenic Sequences and Sites from Intrahost Evolution (LASSIE) uses transmitted founder loss to identify virus "hot-spots" under putative immune selection and chooses sequences that represent recurrent mutations in selected sites. LASSIE favors earliest sequences in which mutations arise. With well-characterized longitudinal Env sequences, we confirmed selected sites were concentrated in antibody contacts and selected sequences represented diverse antigenic phenotypes. Practical applications include rapidly identifying immune targets under selective pressure within a subject, selecting minimal sets of reagents for immunological assays that characterize evolving antibody responses, and for immunogens in polyvalent "cocktail" vaccines.
Developmental Potential of Bovine Androgenetic and Parthenogenetic Embryos: A Comparative Study1 (2004)

In this study, we compared the developmental capacity of bovine haploid and diploid androgenetic and parthenogenetic embryos obtained by different methods. Androgenetic embryos were produced by piezo-intracytoplasmic sperm injection (ICSI) or in vitro fertilization (IVF) of enucleated oocytes with or without subsequent pronuclear transfer from one haploid zygote to another. Parthenogenetic embryos were obtained by activation of matured oocytes by ionomycin combined with cycloheximide or 6-dimethylaminopurine (DMAP) treatment. Only few cleaved androgenetic haploid embryos were able to compact (2.7%) and to form blastocysts (1.8%), while significantly more haploid parthenogenotes underwent compaction (24-37%) and a minority developed to blastocysts at different rates, depending on the activation procedure (cycloheximide 3%, 6-DMAP 14.5%). By contrast, development to blastocyst of diploid androgenotes, cloned androgenetic embryos, and parthenogenotes (31%, 39%, and 43%, respectively) was similar to IVF control embryos (35%). Cell number on Day 7 was higher for IVF blastocysts and decreased in consecutive order in diploid androgenotes, diploid parthenogenotes, and haploid uniparental embryos. Following transfer of diploid androgenetic embryos, a pregnancy was established and maintained up to Day 28.

The structure is a 2π/3-mode disk-loaded structure with group velocity of 22% of the speed of light and a total length of about 300mm. It is build with copper disks brazed together. This note presents the design and the fabrication of this structure, as well as the RF measurement results.
A statistical methodology for deriving reservoir properties from seismic data (1995)

Abstract The use of seismic data to better constrain the reservoir model between wells has become an important goal for seismic interpretation.We propose a methodology for deriving soft geologic information from seismic data and discuss its application through a case study in offshore Congo. The methodology combines seismic facies analysis and statistical calibration techniques applied to seismic attributes characterizing the traces at the reservoir level. We built statistical relationships between seismic attributes and reservoir properties from a calibration population consisting of wells and their adjacent traces. The correlation studies are based on the canonical correlation analysis technique, while the statistical model comes from a multivariate regression between the canonical seismic variables and the reservoir properties, whenever they are predictable.In the case study, we predicted estimates and associated uncertainties on the lithofacies thicknesses cumulated over the reservoir interval from the seismic information. We carried out a seismic facies identification and compared the geological prediction results in the cases of a calibration on the whole data set and a calibration done independently on the traces (and wells) related to each seismic facies. The later approach produces a significant improvement in the geological estimation from the seismic information, mainly because the large scale geological variations (and associated seismic ones) over the field can be accounted for.
The molecular aspect of the double absorption peak in the dielectric spectrum of the antiferroelectric liquid crystal phase (1995)

Abstract The dielectric spectrum of the antiferroelectric smectic C∗ phase exhibits a low and a high frequency absorption peak (Pl, Ph) which have been studied as a function of temperature and bias electric field. Measurements from 10 Hz to 10 MHz were carried out with smectic layers parallel and quasi-perpendicular to the cell plates for the multicomponent mixture CS-4000 (Chisso). In addition to the orthogonal smectic A∗ phase, this material has four tilted phases, three narrow phases with a dielectric behaviour permitting us to classify two of them as C∗α (82·80° to 81·91°C) and C∗γ (80·10° to 79.17°C), and one broad antiferroelectric phase (79.17° to −10°C). On applying an increasing bias field, Δ∊ for both processes first increases by about a factor of two, then exhibits a maximum at a threshold field E c corresponding to the antiferroelectric-ferroelectric transition at which it decreases by almost one order of magnitude. In fact, at E c the PH peak vanishes and the PL peak shows up at a frequency slightly lower than that corresponding to zero field. In contrast to the Δ∊ behaviour, the relaxation frequency of the two absorptions does not show any appreciable bias field dependence for E < E c. We attribute the PH process to the collective reorientation of the molecules around the cone in the opposite direction (anti-phase in the Ø variable). PL may be attributed to a similar collective reorientation in the same direction (in-phase) around the cone, where the coupling to the electric field is mediated by the helical superstructure, and a corresponding small shift in the local polarization directions. There is no antiferroelectric soft mode coupling to an electric field, but the anti-phase cone motion acts electro-optically in a way similar to the electroclinic effect.
Flexible Carbon Nanotubes Confined Yolk-Shelled Silicon-Based Anode with Superior Conductivity for Lithium Storage (2021)

The further deployment of silicon-based anode materials is hindered by their poor rate and cycling abilities due to the inferior electrical conductivity and large volumetric changes. Herein, we report a silicon/carbon nanotube (Si/CNT) composite made of an externally grown flexible carbon nanotube (CNT) network to confine inner multiple Silicon (Si) nanoparticles (Si NPs). The in situ generated outer CNTs networks, not only accommodate the large volume changes of inside Si NPs but also to provide fast electronic/ionic diffusion pathways, resulting in a significantly improved cycling stability and rate performance. This Si/CNT composite demonstrated outstanding cycling performance, with 912.8 mAh g<sup>-1</sup> maintained after 100 cycles at 100 mA g<sup>-1</sup>, and excellent rate ability of 650 mAh g<sup>-1</sup> at 1 A g<sup>-1</sup> after 1000 cycles. Furthermore, the facial and scalable preparation method created in this work will make this new Si-based anode material promising for practical application in the next generation Li-ion batteries.
