Tautonia sociabilis gen. nov., sp. nov., a novel thermotolerant planctomycete, isolated from a 4000 m deep subterranean habitat (2019)

A novel aerobic bacterium, designated as strain GM2012<sup>T</sup>, was isolated from a microbial mat proliferating under the flow of thermal water dissipating from the wall of a 4000 m deep mine in South Africa. The cells were non-motile cocci, capable of budding, occurred in single or gathered in aggregates. The organism is a strictly aerobic chemoorganoheterotroph, preferring simple sugars and polysaccharides as growth substrates. The optimal growth occurred at 42 °C and pH 7.5-7.7. The predominant fatty acids were palmitate, stearate and oleate. The G+C content of the DNA was 70.1 mol%. The 16S rRNA gene sequence analysis placed strain GM2012<sup>T</sup> within the family Isosphaeraceae of the order Planctomycetales with 88-89 % sequence identity to Isosphaera pallida, Aquisphaeragiovannonii, Singulisphaera acidiphila, Paludisphaera borealis and Tundrisphaera lichenicola type strains. Based on the genotypic and phenotypic distinctive features of the new strain, we propose a novel genus and species Tautonia sociabilis gen. nov., sp. nov. with the type strain GM2012<sup>T</sup> (=VKM B-2860,=KCTC 72013).

Membrane topologies of the PGLa antimicrobial peptide and a transmembrane anchor sequence by Dynamic Nuclear Polarization/solid-state NMR spectroscopy (2016)

Dynamic Nuclear Polarization (DNP) has been introduced to overcome the sensitivity limitations of nuclear magnetic resonance (NMR) spectroscopy also of supported lipid bilayers. When investigated by solid-state NMR techniques the approach typically involves doping the samples with biradicals and their investigation at cryo-temperatures. Here we investigated the effects of temperature and membrane hydration on the topology of amphipathic and hydrophobic membrane polypeptides. Although the antimicrobial PGLa peptide in dimyristoyl phospholipids is particularly sensitive to topological alterations, the DNP conditions represent well its membrane alignment also found in bacterial lipids at ambient temperature. With a novel membrane-anchored biradical and purpose-built hardware a 17-fold enhancement in NMR signal intensity is obtained by DNP which is one of the best obtained for a truly static matrix-free system. Furthermore, a membrane anchor sequence encompassing 19 hydrophobic amino acid residues was investigated. Although at cryotemperatures the transmembrane domain adjusts it membrane tilt angle by about 10 degrees, the temperature dependence of two-dimensional separated field spectra show that freezing the motions can have beneficial effects for the structural analysis of this sequence.
[Distribution of phosphine and microorganisms in partial sediments of Lake Taihu]. (2006)

Phosphine in Lake Taihu sediment cores were monitored by a GC/NPD method, coupled with cryo-trapping enrichment technology. Results show that phosphine is universally detected in sediment cores, its concentration ranges from 0.15 ng/kg to 36.1 ng/kg. The concentration of phosphine varies with different sampling sites and depths. Representative microorganisms (aerobic bacteria, anaerobic bacteria, actinomycete, inorganic phosphobacteria and organic phosphobacteria) in surface sediments were also identified. The amount and distribution of microorganisms positively correlate with different contamination and salty levels of the samples. A markedly positive linear correlation between the concentration of phosphine and the numbers of inorganic phosphobacteria could be observed (R2 = 0.817, n = 6). There is not a correlation between phosphine level and organic phosphobacteria quantities.
Molecular detection of fungal communities in soil (2005)

Fungi are an important group of microorganisms inhabiting a diverse range of ecosystems (1). The majority of fungi are multicellular organisms. They can have a sexual and/
or asexual lifecycle with numerous species forming fruiting bodies and producing large 
numbers of spores. Due to their ﬁlamentous growth, fungi are highly efﬁcient in mineralizing virtually any organic substrate. Saprotrophic fungi colonize dead substrates, while 
necrotrophic and mutualistic fungal species colonize living tissues by means of highly 
specialized infection structures. Several fungal species have antagonistic properties that 
prevent the development of other potentially pathogenic fungi and bacteria.
Schichtartig aufgebaute dendritische Block-Copolymere (1998)

Eine strahlenförmige Molekülgestalt und eine Schichtstruktur zeichnen die Titelverbindungen aus, wobei die Schichten aus Polymeren hoher Molekülmasse bestehen. Ein mit sechs Hydroxygruppen funktionalisierter Kern diente als Initiator für die Ringöffnungspolymerisation von ε-Caprolacton, die zu einem sechsarmigen Sternpolymer führte. Durch Verknüpfung der Kettenenden mit funktionalisierten Dendronen erhielt man die zweite Schicht des dendritischen Block-Copolymers mit 12, 24 oder 48 peripheren Hydroxygruppen (je nach Generation des verwendeten Dendrons). Diese Makromoleküle fungierten als „Makroinitiatoren”︁ beim Anbau einer weiteren Schicht von Poly(ε-caprolacton), der dritten Generation des dendritischen Blockpolymers.

Evidence of active oviposition avoidance to systemically applied imidacloprid in the Colorado Potato Beetle ( Leptinotarsa decemlineata ) (2022)

Abstract Agricultural pests can develop behavioral resistance to insecticides via choosing to feed or oviposit on non-toxic hosts. As young larvae have relatively low mobility, oviposition preferences from female adults may play a critical role in shaping the evolutionary trajectory of pest populations. While oviposition avoidance of toxic hosts was found in different agriculture pests, it remains unclear whether such preferences can be learned from female adults. To address this question, we investigated feeding and oviposition preferences to imidacloprid in the Colorado Potato Beetle (CPB, Leptinotarsa decemlineata ), a major potato pest. We first identified two CPB strains that have different levels of resistance to imidacloprid. Then, we performed choice assays in the two strains and found that both strains did not have an innate feeding avoidance to systemically applied imidacloprid at both larval and adult stages. Further oviposition choice assays showed that the susceptible strain preferred to lay eggs on insecticide-free plants while the resistant strain did not. Analysing moving patterns of the two strains suggested that the oviposition preference is likely due to active learning by the female adults. Together, these results indicate that CPB can have active oviposition avoidance, which might have contributed to the rapid global invasion of this agricultural pest.
ρ0photoproduction in ultraperipheral relativistic heavy ion collisions atsNN=200GeV (2008)

Photoproduction reactions occur when the electromagnetic field of a relativistic heavy ion interacts with another heavy ion. The STAR Collaboration presents a measurement of 0 and direct + -photoproduction in ultraperipheral relativistic heavy ion collisions at s NN = 200 GeV. We observe both exclusive photoproduction and photoproduction accompanied by mutual Coulomb excitation. We find a coherent cross section of (AuAu Au * Au * 0 ) = 530 19(stat.) 57(syst.) mb, in accord with theoretical calculations based on a Glauber approach, but considerably below the predictions of a color dipole model. The 0 transverse momentum spectrum (p 2 T ) is fit by a double exponential curve including both coherent and incoherent coupling to the target nucleus; we find inc / coh = 0.29
Lung lamellar body amphiphilic topography: A morphological evaluation using the continuum theory of liquid crystals: II. Disclinations, edge dislocations, and irregular defects (1988)

The bilayers in normal mammalian and human lung multilamellar bodies (LMB) are parallel, equally spaced, and continuous--a configuration that minimizes the large elastic strain energy associated with changing the equilibrium bilayer separation and the hydrophobic-hydrophilic repulsion energy between the hydrocarbon tails of phospholipid and the aqueous phase. This ideal behavior is disrupted at a limited population of large Burgers vector edge dislocations dissociated into +/- 1/2 disclination pairs. The configuration and interaction of the defects are explained by the continuum theory of liquid crystals and are shown to be identical to defects observed in in vitro surfactant liposomes and bilayers. We report the first observations with molecular resolution of the core structure of a liquid crystal dislocation. Defect cores are shown to be located between both headgroups and tailgroups in human LMB, suggesting that both types of core are similar in energy. This may be the result of partitioning of proteins or other nonlipid impurities in the LMB to the defect cores, which might also change the stability of the dislocations to favor their preservation. The edge dislocation defects interact in ways that minimize their overall strain energy. A population of edge dislocations may play an important role in the transport or localization of certain molecules through the lamellar body. Certain defects were observed in lung multilamellar bodies that have not been observed in in vitro systems; these are probably due to the complex, multicomponent nature of the LMB surfactant and the dynamic, in vivo environment of the LMB.
Spaces-A Replication Scheme for Sharing Tagged Files in Hybrid Wireless Networks (2007)

Spaces is a replication scheme for sharing files enriched with meta-information in hybrid wireless networks. It relies on existing standards and prevalent technologies. Realized as a URI scheme, spaces allow a seamless integration with current systems in a platform-independent manner. Feeds are used as a basis to exchange data among subscribers to the Space, both within local groups in a self-organizing fashion as well as from the Internet, depending on connectivity. Tagging is employed, enabling to label and quickly identify relevant content. Additional meta-information is used in order to allow resolving files residing in the Space locally, independently of their physical location.
GNSS-R altimeter performance: Analysis of Cramer-Rao lower bounds (2012)

Earth-reflected Global Navigation Satellite System-signals have become an attractive tool for remote sensing, being proposed as a means to perform ocean altimetry, among many other applications. The technique exploiting navigation signals is widely known as GNSS-R. In this paper the well-known Cramer-Rao lower bound is used to predict the sea surface height estimation precision of a GNSS-R based spaceborne altimeter, exploiting the open-access GPS L1 C/A code signal. Real spaceborne data acquired by the GPS-R receiver on-board UK-DMC satellite is used to extract statistical properties of spaceborne GPS reflected signals.
On the measurement of a weak classical force coupled to a harmonic oscillator: experimental progress (1996)

Several high-precision physics experiments are approaching a level of sensitivity at which the intrinsic quantum nature of the experimental apparatus is the dominant source of fluctuations limiting the sensitivity of the measurements. This quantum limit is embodied by the Heisenberg uncertainty principle, which prohibits arbitrarily precise simultaneous measurements of two conjugate observables of a system but allows one-time measurements of a single observable with any precision. The dynamical evolution of a system immediately following a measurement limits the class of observables that may be measured repeatedly with arbitrary precision, with the influence of the measurement apparatus on the system being confined strictly to the conjugate observables. Observables having this feature, and the corresponding measurements performed on them have been named quantum nondemolition or back-action evasion observables. In a previous review (Caves et al., 1980, Rev. Mod. Phys. 52, 341) a quantum-mechanical analysis of quantum nondemolition measurements of a harmonic oscillator was presented. The present review summarizes the experimental progress on quantum nondemolition measurements and the classical models developed to describe and guide the development of practical implementations of quantum nondemolition measurements. The relationship between the classical and quantum theoretical models is also reviewed. The concept of quantum nondemolition and back-action evasion measurements originated in the context of measurements on a macroscopic mechanical harmonic oscillator, though these techniques may be useful in other experimental contexts as well, as is discussed in the last part of this review.

Dipeptide metalloendoprotease substrates are glucose transport inhibitors and membrane structure perturbants (1986)

Dipeptide substrates for metalloendoproteases have previously been shown to block biological processes requiring membrane fusion. Thus, we employed such compounds as potential inhibitors of the insulin-dependent activation of glucose transport in fat cells. This event is thought to involve vesicle movement from an intracellular site to the cell surface and would therefore require membrane fusion during the activation step. We find that synthetic dipeptides which are metalloendoprotease substrates rapidly and reversibly inhibit insulin-activated glucose oxidation in a dose-dependent manner but exhibit essentially no effect on basal levels. A similar result is obtained when glucose transport is measured directly in intact fat cells, in metabolically poisoned cells, and in isolated membrane vesicles derived from insulin-activated or untreated fat cells. That is, the dipeptide substrates inhibit insulin-activated glucose uptake to a greater extent than basal transport, and they do so even when vesicle translocation and fusion have already taken place as in ATP-depleted cells and isolated vesicles. Onset of transport inhibition after dipeptide addition is rapid, but not instantaneous, with a t 1/2 of 15-30 s. The metalloendoprotease substrates also inhibit glucose uptake and cytochalasin B binding in human erythrocytes but not in human placental microsomes. Finally, light microscopic examination of substrate-treated red cells reveals marked cupping and/or echinolation of the cell membrane. We conclude the following from these observations: Metalloendoprotease substrates are inhibitors of adipocyte glucose transport.(ABSTRACT TRUNCATED AT 250 WORDS)
Vehicle–space traffic-state estimation of a motorway corridor with slip roads (2018)

Traffic-state estimation is a key component of an advanced traffic management system. The Eulerian traffic-state estimation based on an X-T traffic-flow model has proved successful in processing traditional X-T data sources such as inductive loop data. However, over the past decade, the emergence of probe vehicle data from paired sensors has created challenges for X-T traffic-state estimation. The vehicle–space (N-X) model has shown potential benefits in modelling paired-probe data. In this paper, an original N-X traffic-state estimation framework is proposed and validated by numerical experiments. In addition, an original first-order conservation formulation is derived to address the entry and exit slip road issue for motorway corridors. An evaluation is conducted by comparing the proposed N-X estimation with the X-T estimation. The results show that the proposed model is superior to the X-T estimation in terms of accuracy and efficiency. It performs well, particularly during congestion, and can track traffic breakdowns and recoveries effectively.
Phase separation of two-dimensional Coulombic crystals of mesoscale dipolar particles from mesoscale polarizable “solvent” (2009)

This letter describes the formation of two-dimensional (2D) crystals of dipolar particles (TN) made of electrostatically charged, joined, millimeter-scale Teflon (T) and nylon-6,6 (N) spheres, and the separation of these crystals, as a distinct phase, from a mixture of TN and similar, capacitively charged particles that were coated with gold (Au2). The extent of separation increased with increasing amplitude of agitation, and with decreasing density of particles. Above a threshold in the amplitude of agitation, the crystals broke apart and the particles remixed. This system is a 2D model of the nucleation of crystals of polar molecules in a polarizable liquid.

A Hybrid Solenoid Coupler for Wireless Charging Applications (2018)

This paper introduces a primary pad for wireless charging applications, which is able to transfer high power over large air gaps and is tolerant to lateral displacements suitable for electric vehicle charging applications. The developed pad is an improved solenoid designed specifically to address issues such as flux leakage and loss while retaining good coupling. It is a hybrid structure that consists of a combination of rectangular- or square-shaped coils and a central solenoid, all connected in series. When energized, it produces a single-sided, polarized flux similar to the flux pattern of the solenoid and double D (DDP) pads. The power transfer capability of this pad is investigated through finite-element analysis simulations. The results are compared first to a similar sized solenoid from which it was derived, and also a DDP primary pad and are verified through measurements on prototype systems in the laboratory. The aim of this paper is to provide an improved hybrid solenoid pad showing higher coupling factors and lower stray field emissions with a performance (coupling and stray field emissions) similar to that of DDPs.

Neural Algorithms for Low Power Implementation of Partial Differential Equations (2018)

The rise of low-power neuromorphic hardware has the potential to change high-performance computing; however much of the focus on brain-inspired hardware has been on machine learning applications. A low-power solution for solving partial differential equations could radically change how we approach large-scale computing in the future. The random walk is a fundamental stochastic process that underlies many numerical tasks in scientific computing applications. We consider here two neural algorithms that can be used to efficiently implement random walks on spiking neuromorphic hardware. The first method tracks the positions of individual walkers independently by using a modular code inspired by grid cells in the brain. The second method tracks the densities of random walkers at each spatial location directly. We present the scaling complexity of each of these methods and illustrate their ability to model random walkers under different probabilistic conditions. Finally, we present implementations of these algorithms on neuromorphic hardware.
