Suppression of Octahedral Tilts and Associated Changes in Electronic Properties at Epitaxial Oxide Heterostructure Interfaces (2010)

Epitaxial oxide interfaces with broken translational symmetry have emerged as a central paradigm behind the novel behaviors of oxide superlattices. Here, we use scanning transmission electron microscopy to demonstrate a direct, quantitative unit-cell-by-unit-cell mapping of lattice parameters and oxygen octahedral rotations across the BiFeO3-La0.7 Sr0.3 MnO3 interface to elucidate how the change of crystal symmetry is accommodated. Combined with low-loss electron energy loss spectroscopy imaging, we demonstrate a mesoscopic antiferrodistortive phase transition near the interface in BiFeO3 and elucidate associated changes in electronic properties in a thin layer directly adjacent to the interface.
Integrated Horn Antenna for Microstrip Waveguide THz Quantum Cascade Lasers (2007)

A horn-antenna is integrated on a microstrip waveguide QCL emitting at 2.0 THz. This allows a better impedance match to free space, which improves substantially the directivity of the beam and the radiation outcoupling.
Effects of group size on school structure and behaviour in yellow‐eyed mulletAldrichetta forsteri (2018)

Schooling behaviour in yellow-eyed mullet Aldrichetta forsteri, a common fish species in New Zealand estuarine habitats, was investigated to identify interaction rules associated with group formation. Tank-based three-dimensional studies of three group sizes (15, 75 and 150 individuals) were carried out to measure the effects of these different group sizes on school structure during control, predation risk and foraging behavioural states. Increased group size positively correlated with nearest-neighbour distance in control and foraging states. Swimming speed was the lowest in all three behavioural states in groups of 15 fish compared with 75 or 150. Immediate behavioural response following visual exposure to a simulated avian predator differed between groups resulting in loss of structure in larger groups. School shape was an oblong-oblate spheroid with a length, breadth and height ratio of 5:2:1 and the area of free space surrounding individual fish was spherical in shape with a high degree of spatial isotropy present in all size groups. These findings challenge traditional theories based on either local or global properties as key drivers of group structure. Instead, our results suggest that a more collaborative approach involving both group size and rules pertaining to nearest-neighbour interactions affects collective behaviours in this species.
Lipid hydroperoxide‐induced apoptosis in human colonic CaCo‐2 cells is associated with an early loss of cellular redox balance (2000)

Apoptosis plays a critical role in maintaining homeostasis of the intestinal epithelium. Dietary oxidants like peroxidized lipids could perturb cellular redox status and disrupt mucosal turnover. The objective of this study was to delineate the role of lipid hydroperoxide (LOOH) -induced redox shifts in intestinal apoptosis using the human colonic CaCo-2 cell. We found that subtoxic concentrations of LOOH increased CaCo-2 cell apoptosis. This LOOH-induced apoptosis was associated with a significant decrease in the ratio of reduced glutathione-to-oxidized glutathione (GSH/GSSG), which preceded DNA fragmentation by 12 to 14 h, suggesting a temporal relationship between the two events. Oxidation of GSH with the thiol oxidant diamide caused significant decreases in cellular GSH and GSH/GSSG at 15 min that correlated with the activation of caspase 3 (60 min) and cleavage of PARP (120 min), confirming a temporal link between induction of cellular redox imbalance and initiation of apoptotic cell death. These kinetic studies further reveal that oxidant-mediated early redox change (within 1 h) was a primary inciting event of the apoptotic cascade. Once initiated, the recovery of redox balance did not prevent the progression of CaCo-2 cell apoptosis to its biological end point at 24 h. Collectively, the study shows that subtoxic levels of LOOH disrupt intestinal redox homeostasis, which contributes to apoptosis. These results provide insights into the mechanism of hydroperoxide-induced mucosal turnover that have important implications for understanding oxidant-mediated genesis of gut pathology.
Value of Power Doppler Imaging and the Hypoechoic Halo in the Sonographic Detection of Foreign Bodies (2003)

Sonography is an effective and sensitive tool for the detection of soft tissue foreign bodies. The use of power Doppler imaging may aid in detection of possible foreign bodies by increasing the conspicuity of both the hypoechoic halo and the foreign body itself.
Human spinal cord neurons in dissociated monolayer cultures: morphological, biochemical, and electrophysiological properties (1985)

The preparation of dissociated monolayer cultures from embryonic human spinal cord is described. Optimal survival was achieved with embryonic tissue between the eighth and ninth week. The neurons survive for as long as 7 weeks in culture and they grow in a standard tissue culture medium which contains 13% decomplemented human serum. The neurons have been identified by indirect immunofluorescence techniques using antibodies to tetanus toxin and neurofilament protein. Our biochemical studies demonstrate the presence of cholinergic and GABAergic neurons. Cholinergic neurons develop in culture and are more numerous in the cultures prepared from the anterior part of the spinal cord as compared to those from the posterior part. Therefore, it is possible that a large part of the cholinergic neurons derive from the motoneuron pool. Electrical membrane properties were studied with patch electrodes using the whole cell recording technique. Neurons had short duration action potentials that could be blocked by tetrodotoxin (TTX). Voltage clamp experiments combined with the use of pharmacological blocking agents revealed the presence of several voltage- and time-dependent currents: a sodium current sensitive to TTX, a potassium current made up of two components, sensitive to tetraethylammonium and 4-aminopyridine, and a calcium current sensitive to cobalt. From a biochemical and electrophysiological point of view the properties of human spinal cord neurons in culture closely resemble the properties of spinal cord neurons from other species.
Primary localised amyloidosis of the orbit. (1996)

There is a characteristic clinical and radiological pattern for primary localised amyloidosis of the orbit. The disease process is truly local and not part of a systemic process. A majority respond to simple debulking with subsequent observation.
Semiempirical potentials for alkali-noble gas interactions (1974)

A semiempirical calculation of alkali-noble gas interatomic potentials applicable to excited states of the alkali at internuclear separations and energies important for the interpretation of optical line broadening experiments is presented. The assignment of a single adjustable parameter is based on a comparison with scattering cross-section measurements of ground state potentials. Evidence that the repulsive interaction scales as the collision cross section of the noble gas atoms for low energy electrons is presented, and simple formulas are developed to predict potentials for all alkali-noble gas combinations as a function of noble gas dipole and quadrupole polarizabilities and alkali unperturbed energy. Additional comparisons are made with data from satellite bands in Cs–Xe and Cs–Kr spectra, and the impact broadening and shift of alkali spectral lines at low foreign gas pressure is calculated from the predicted potentials and compared with available experimental data.
Network coding meets information-centric networking (2012)

User behavior in the Internet has changed over the recent years towards being driven by exchanging and accessing information. Many advances in networking technologies have utilized this change by focusing on the content of an exchange rather than on the endpoints exchanging the content, in particular to better support mobility. Network coding and information-centric networking are two examples of these trends, each being developed largely independently thus far. This paper brings these areas together at the internetworking layer. We outline opportunities for applying network coding in a novel and performance-enhancing way that could push forward the case for information-centric networking itself.
ACCURATE SILICON SPACER CHIPS FOR AN OPTICAL FIBER CABLE CONNECTOR (1977)

A multi-fiber splicing technigue developed by Bell Laboratories, Atlanta is presently being used in the Atlanta fiberguide experiment. This optical fiber connector consists of two properly prepared cable terminations butted end to end. The cable termination is a laminate sandwich of alignment chips with grooves on both top and bottom surfaces interleaved with optical fibers epoxied to form a stacked array.
Ink Dependence of Poly(dimethylsiloxane) Contamination in Microcontact Printing (2006)

Poly(dimethylsiloxane) (PDMS) is the most widely used stamp material in microcontact printing. It has excellent properties with respect to versatility, chemical inertness, and mechanical stability. However, it has an inclination to contaminate printed substrates with low molecular weight siloxane fragments. In this study, it is shown, by a combination of lateral force microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy, that the extent of the PDMS-induced contamination is dependent on the nature of the ink used. The highest degree of contamination was found for relatively polar inks, whereas apolar alkanethiol inks were found to shield the substrate from contamination. This is interpreted in terms of the contaminating species being polar in nature.
Manufacture and Properties of Bifidogenic Saccharides Derived from Wood Mannan (2012)

Pinus pinaster wood samples were subjected to double hydrothermal processing. The liquors coming from the second stage, containing soluble saccharides of polymeric or oligomeric nature from hemicelluloses (POHs), were subjected to membrane processing (operating in discontinuous diafiltration) for refining and fractionation. Refined POH fractions were characterized by matrix-assisted laser desorption/ionization time of flight mass spectrometry and chromatographic techniques. The most complex POH component was made up of 14 hexoses and contained 4 acetyl groups. The fermentability of purified POHs by human fecal inocula was assessed by measuring both carbon source consumption and formation of short-chain fatty acids. The bifidogenic ability of POHs was confirmed by fluorescence in situ hybridization. The stimulatory effects on the bifidobacterial population reached by POHs were of the same order as those obtained with commercial fructooligosaccharides.

The derivation of the analytical structure of a class of Interval type-2 fuzzy PD and PI controllers (2011)

Analytical structure of a fuzzy logic system (FLS) is to establish its mathematical input-output relationship. In this paper, the analytical structure of a class of Interval type 2 (IT2) fuzzy PD and PI controllers are derived by dividing the input space and identifying the input-output relationship for each region. Unlike the symmetric fuzzy PD and PI controller [12] which have three different consequent sets H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> <; H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> = H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> <; H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> , the IT2 fuzzy PD and PI controllers considered in this paper have four different consequent sets H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">4</sub> <; H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> <; H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> <; H <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sub> . Compared with the symmetric IT2 fuzzy controllers investigated in [12], the relatively large number of divisions of the input space indicates the potential of this class of IT2 fuzzy controllers in achieving better performance. The equations describing the input output relationship for each region provide mathematical tools for further investigations of these IT2 fuzzy PD controllers.
Effectiveness of several polyunsaturated seed oils as boll weevil feeding deterrents (1981)

Abstract Prompted by the previous discovery that (9Z,11E,13E)‐9,11,13‐octadecatrienoic acid (α‐eleostearic acid) was one of the compo‐nents responsible for the boll weevil feeding deterrency of tung oil, the seeds of 11 other plant species were extracted with pentane and the oils were evaluated for their feeding deterrency in the laboratory. The oils of Calendula suffruticosa, Centrantbus macro‐siphon, Jacaranda mimosifolia and Momordica cochincbinenis were effective feeding deterrents for the boll weevil.

FRET Microscopy in 2010: The Legacy of Theodor Förster on the 100th Anniversary of his Birth (2010)

Theodor Förster would have been 100 years old this year, and he would have been astounded to see the impact of his scientific achievement, which is still evolving. Combining his quantitative approach of (Förster) resonance energy transfer (FRET) with state-of-the-art digital imaging techniques allows scientists to breach the resolution limits of light (ca. 200 nm) in light microscopy. The ability to deduce molecular or particle distances within a range of 1-10 nm in real time and to prove or disprove interactions between two or more components is of vital interest to researchers in many branches of science. While Förster's groundbreaking theory was published in the 1940s, the availability of suitable fluorophores, instruments, and analytical tools spawned numerous experiments in the last 20 years, as demonstrated by the exponential increase in publications. These cover basic investigation of cellular processes and the ability to investigate them when they go awry in pathological states, the dynamics involved in genetics, and following events in environmental sciences and methods in drug screening. This review covers the essentials of Theodor Förster's theory, describes the elements for successful implementation of FRET microscopy, the challenges and how to overcome them, and a leading-edge example of how Förster's scientific impact is still evolving in many directions. While this review cannot possibly do justice to the burgeoning field of FRET microscopy, a few interesting applications such as threecolor FRET, which greatly expands the opportunities for investigating interactions of cellular components compared with the traditional two-color method, are described, and an extensive list of references is provided for the interested reader to access.
Analysis of the tubular motor with Halbach and radial magnet array (2003)

In the machine tool industry, direct drive linear motor technology is of increasing interest as a means to achieve high acceleration, and to increase reliability. This paper analyzes and compares the characteristics of tubular motor with Halbach and radial magnet array respectively. The governing equations established analytically in terms of vector potential, two dimensional cylindrical coordinate system and Maxwell's equations. We derive magnetic field solutions due to the PMs and to the currents. Motor thrust, flux linkage, back emf are then derived. The results are shown in good conformity with those obtained from the commonly used finite element method.
Physical Implementation of an Asynchronous 3D-NoC Router Using Serial Vertical Links (2011)

This paper details the design and implementation of an asynchronous 3D-NoC router using a novel serialization scheme in the vertical directions which targets 3D production oriented processes. A study of the router cost has been conducted for medium and high density TSVs on 65nm and 32nm nodes. A router integrating the serial link has been implemented in 65nm using medium density TSVs. The serial link provides a throughput of 16 Gb/s for an area gain of 57%, and an additional cost of one NoC routing hop in latency and in energy.
Power-law shot noise and its application on modeling of ultrasound echoes (2002)

1/f/sup /spl beta//-type spectral behavior has received considerable attention in the past few years because it arises from a wide range of nature phenomena. Several methods have been proposed for modeling a 1/f/sup /spl beta// process. In this paper we consider a power-law shot noise model, and show that, asymptotically, it gives rise to a power-law /spl alpha/-stable process if /spl beta/<1, or to a process with power-law /spl alpha/-stable increments if 1</spl beta/<3. We show that this model applies to ultrasound rf echoes, with the power-law behavior attributed to tissue attenuation.
Helium ion microscopy: a new tool for imaging novel mesoporous silica and organosilica materials (2013)

Helium ion microscopy (HIM) has been used to image mesoporous silica and organosilica for the first time. Images of chiral nematic silica, ethylenesilica, and new benzenesilica reveal the structural organization, pore dimensions and connectivity of these materials on the nanometer length scale.
Electric and magnetic emission in near field region and thermal behaviour of power module for photovoltaic application (2015)

The new power module, characterized by high power density, miniaturization of packages and layout and high frequency switching, are increasingly used in the field of in automotive, aircraft industry and for Distributed Generation (DG) connected to smart grid. To guarantee the reliability and safety of these systems, the electromagnetic compatibility (EMC) and thermal behavior, have to be carefully considered for these appliances. This paper describes a measurement methodology to characterize the electromagnetic emissions in near field zone produced by a PM prototype and its thermal behavior. In particular, the electric and magnetic fields, in the near field region in the frequency range 9kHz-3GHz is evaluated and an analysis of the temperature values achieved by the module during its operation in different load conditions is presented. The proposed methodology involve the evaluation of the PM electromagnetic and thermal emissions in standalone configuration, i.e. without its control and supply boards, because the aim is to characterize behavior of only the PM and to identify the EMI source and thermal hot-spots inside the power section.

Branching and Cross-Linking in Radiation-Modified Poly(tetrafluoroethylene):  A Solid-State NMR Investigation (1999)

Fluoropolymers exhibit a number of favorable properties such as high-temperature stability, chemical resistivity, and a low surface energy. However, the possibility to incorporate fluoropolymers into other materials is limited because of the low surface energy. Modification procedures such as radiation modification can be applied to overcome these difficulties. High-resolution fluorine-19 solid-state NMR using high-speed magic-angle sample spinning has been applied to investigate the structural changes resulting from irradiation of poly(tetrafluoroethylene) (PTFE) with high-energy electrons under vacuum. PTFE irradiated at room temperature mainly shows chain scission. PTFE irradiated at high temperatures, above the melting point, under vacuum, however, contains branches as well as cross-links. Evidence for cross-links in this material is derived from structural information. A quantitative analysis of the data is used to establish the density of side groups and branches. The excess of branches to end groups is interpreted as cross-links.
Analysis of door seal structure of microwave oven with consideration of higher modes by the FDTD method (2002)

Abstract This paper focuses on the choke structure, which is generally used in suppressing the leakage wave from the door gap of microwave ovens. A choke structure which simulates the interdigital periodic choke structure for mass‐produced microwave ovens is considered, and the shielding effect is examined by the FDTD method for leaky waves (hybrid waves) including the higher modes, as a situation very close to practice. As an application of such an analysis to the optimal design of the choke groove, the shielding effect is examined as a function of the angle of the metal plates composing the choke groove. It is shown that the proposed method of analysis is effective for such a complex structure. © 2002 Scripta Technica, Electron Comm Jpn Pt 2, 85(3): 50–57, 2002
