Adrenergic Control of α-Melanocyte-Stimulating Hormone Release in Frog Pituitary Is Mediated by both β- and a Nonconventional α<sub>2</sub>-Subtype of Adrenoreceptors (1995)

Previous studies have shown that melanotrope cells of the pars intermedia of Rana ridibunda are inhibited by dopaminergic D2 agonists and stimulated by beta-adrenergic agonists. In the present study, we have examined the possible involvement of alpha-adrenoreceptors in the regulation of frog melanotrope cells. Reversed-phase HPLC analysis combined with electrochemical detection revealed the presence of both dopamine and noradrenaline in pars intermedia extracts (74.1 and 3.2 ng/mg protein, respectively), while adrenaline was undetectable. Administration of graded doses of noradrenaline and adrenaline (from 0.1 to 10 microM) to perifused frog neurointermediate lobes induced a dose-dependent inhibition of alpha-MSH release. The inhibitory effect of adrenaline was partially blocked by the D2-dopaminergic antagonist sulpiride and totally suppressed by concomitant administration of sulpiride and yohimbine (an alpha 2-adrenergic antagonist). Conversely, in the presence of sulpiride, noradrenaline provoked a strong stimulation of alpha-MSH secretion which was totally blocked by the beta-adrenergic antagonist propranolol. Taken together, our results indicate that endogenous catecholamines may exert a complex regulatory action on frog melanotrope cells through activation of dopaminergic D2, alpha 2- and beta-adrenergic receptors.
Improving Nanoprobes Using Surface-Enhanced Raman Scattering from 30-nm Hollow Gold Particles (2006)

We report the development of nanoprobes that exploit the surface-enhanced Raman scattering (SERS) from nonaggregated, hollow, gold nanospheres (HGNSs). The homogeneity of the HGNSs leads to a nearly 10-fold improvement in signal consistency over standard silver SERS substrates, which translates into a significant increase in sensitivity and dynamic range for the model application of pH sensing. Moreover, the small size (30-nm diameter) of these SERS-active nanoparticles represents a major step in advancing sensing technology based on SERS, making this technology more amenable to intracellular sensing.
Tight bounds for the partial-sums problem (2004)

We close the gaps between known lower and upper bounds for the online partial-sums problem in the RAM and group models of computation. If elements are chosen from an abstract group, we prove an Ω(lg n) lower bound on the number of algebraic operations that must be performed, matching a well-known upper bound. In the RAM model with b-bit memory registers, we consider the well-studied case when the elements of the array can be changed additively by δ-bit integers. We give a RAM algorithm that achieves a running time of Θ(1 + lg n / lg(b / δ)) and prove a matching lower bound in the cell-probe model. Our lower bound is for the amortized complexity, and makes minimal assumptions about the relations between n, b, and δ. The best previous lower bound was Ω(lg n = (lg lg n+lg b)), and the best previous upper bound matched only in the special case b = Θ(lg n) and δ = O(lg lg n).
THR (Lopremone): Psychobiological Responses of Normal Women (1973)

Ten normal women were injected intravenously with lopremone (thyrotropin releasing hormone) and saline given one to four weeks apart. Lopremone injection caused a sharp rise in thyrotropin (thyroid stimulating hormone, TSH) levels with a return to near-base line levels in three hours. These TSH responses were slightly greater than those previously elicited in depressed women but the difference was statistically insignificant. After lopremone injection, triiodothyronine (T<sub>3</sub>) levels rose more and sooner than thyroxine (T<sub>4</sub>) levels. Neither TSH elevation nor thyroid hormone elevation correlated with the euphoric response experienced by most subjects. This and other evidence suggests a central action of lopremone.
Immune Response of Gnotobiotic Piglets against Mycoplasma hyopneumoniae (2008)

In this study, several cytokine responses were investigated during Mycoplasma hyopneumoniae (Mhp) infection using a gnotobiotic infection model. We found that several inflammatory cytokines (IL-1beta, IL-8, IL-18, and TNF-alpha) and an anti-inflammatory cytokine IL-10 were induced from peripheral blood mononuclear cells (PBMC) of germ-free (GF) piglets stimulated with heat killed Mhp whole antigens, but no IFN-gamma and IL-4 were induced by Mhp. After the intranasal infection of Mhp, IL-1beta, IL-8, IL-18, and IFN-gamma were also detected in the broncho-alveolar lavage fluids (BALF). The antigen-specific IFN-gamma and IL-10 responses after infection of Mhp were gradually suppressed during Mhp infection as well as non-specific immune response to concanavalin A (ConA) and lipopolysacchalide (LPS) at early stage of infection. These results suggested that Mhp infection modulates the immune response of pigs by inducing several cytokines, and causes immuno-suppression of pigs in a gnotobiotic condition.
Impurity and doping effects on the pseudoenergy gap in CeNiSn: A Sn NMR study (1996)

Measurements of $^{119}\mathrm{Sn}$ nuclear spin-lattice relaxation rate, 1/${\mathit{T}}_{1}$, and Knight shift, K, in the off-stoichiometric compound ${\mathrm{CeNi}}_{1.01}$Sn and the substituted compounds ${\mathrm{CeNi}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathit{M}}_{\mathit{x}}$Sn (M=Cu,Co) and ${\mathrm{Ce}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$${\mathrm{La}}_{\mathit{x}}$NiSn have been made in order to unravel the impurity and/or carrier doping effects on the V-shaped gapped state in CeNiSn. From the detailed analysis of the T dependence of 1/${\mathit{T}}_{1}$, it is shown that the density of states (DOS) is induced just at the Fermi level for ${\mathrm{CeNi}}_{1.01}$Sn, whereas the DOS increases progressively with the dopant in a finite-energy range near the Fermi level for the substituted compounds. The respective substitution of Co and La into Ni and Ce sites changes the gapped state into the nonmagnetic Fermi-liquid state, whereas the replacement of Ni by Cu with x\ensuremath{\gtrsim} 0.06 gives rise to the antiferromagnetic (AF) ground state. It is suggested that the AF order is realized by the combined effect of the rapid collapse of the V-shaped gap and the increase of the DOS at the Fermi level. It has been found to lead to the magnetic ground state and the nonmagnetic Fermi-liquid state to dope electrons and holes into the renormalized conduction bands, respectively. \textcopyright{} 1996 The American Physical Society.
Updates on the use of non-invasive brain stimulation in physical and rehabilitation medicine (2009)

Brain stimulation for the treatment of neuropsychiatric diseases has been used for more than 50 years. Although its development has been slow, current advances in the techniques of brain stimulation have improved its clinical efficacy. The use of non-invasive brain stimulation has significant advantages, such as not involving surgical procedures and having relatively mild adverse effects. In this paper we briefly review the use of 2 non-invasive brain stimulation techniques, repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), as therapeutic approaches in physical and rehabilitation medicine. We also compare the effects of non-invasive central nervous system stimulation with techniques of non-invasive peripheral electrical stimulation, in order to provide new insights for future developments. Although the outcomes of these initial trials include some conflicting results, the evidence supports that rTMS and tDCS might have a therapeutic value in different neurological conditions. Studies published within the last year have examined new approaches of stimulation, such as longer intensities of stimulation, new electrode sizes for tDCS, novel coils for stimulation of deeper areas, and new frequencies of stimulation for rTMS. These new approaches need to be tested in larger clinical trials in order to determine whether they offer significant clinical effects.

Membrane Clustering and Bungarotoxin Binding by the Nicotinic Acetylcholine Receptor: Role of the β Subunit (1994)

Nicotinic acetylcholine receptors (nAChRs) are localised at morphologically distinct regions of the post-synaptic membrane by interactions between the receptor subunits and cytoskeletal proteins, such as the 43-kDa protein. We have used Xenopus oocytes to examine the localisation and pharmacological properties of muscle nAChRs associated with 43-kDa protein and to compare them with hybrid muscle nAChRs containing a beta subunit derived from a neuronal source. Receptors expressed on the oocyte outer membrane were visualised using confocal scanning laser microscopy. Coexpression of mouse muscle subunit alpha 1 beta 1 gamma delta and 43-kDa protein transcripts produced discrete receptor aggregates with a diameter of 1-5 microns whose function was partially blocked by application of neuronal bungarotoxin (NBT) at 100 nM. Substitution of the beta 1 subunit by the neuronal beta 2 protein produced a functioning receptor that did not aggregate in the presence of 43-kDa protein and was substantially blocked by the same concentration of NBT. Hybrid alpha 1 beta 4 gamma delta receptors exhibited a combination of characteristics in that they clustered like normal muscle subunits in the presence of 43-kDa protein, but showed a sensitivity to NBT intermediate between that of muscle receptors and that of hybrids containing beta 2. These results suggest that the beta subunit is an important determinant in receptor localisation and sensitivity to NBT.
Experimental test for geminate recombination applied to organic solar cells (2010)

We show that a clear experimental test can distinguish between geminate and nongeminate recombination in low mobility semiconductors. For the particular case of the organic solar cell, the relative contribution of geminate recombination can be determined by measuring transient photoconductivity versus applied voltage. Measurements carried out at room temperature and 200 K on bulk heterojunction organic solar cells fabricated with two different semiconducting polymers show that neither exhibits significant geminate recombination.
APPLICATION OF MAGNETIC REORIENTATION PHASE TRANSITION IN THE STUDY OF EXCHANGE ANISOTROPY (1991)

A Magnetic Reorientation Phase Transition (MRPT) was discovered in 1981 in Molecular-Beam-Epitaxially (MBE) grown thin iron (Fe) films on (110) GaAs substrates. The reorientation transition was characterized by the sudden switching of the in-plane magnetization in the Fe films. Subsequent to this work it was discovered that at low temperatures, the natural oxide on these films becomes antiferromagnetic and provides an exchange anisotropy field. In a ferromagnetic material such as Fe, because of the anisotropic magnetoresistance effect the resistance depends on the angle between the current and the magnetization which is in turn determined by the magnetic energy expression. This paper reviews the application of the MRPT in the study of exchange anisotropy in both the experimental and theoretical aspects.
A Reconfigurable Energy Storage Architecture for Energy-harvesting Devices (2018)

Battery-free, energy-harvesting devices operate using energy collected exclusively from their environment. Energy-harvesting devices allow maintenance-free deployment in extreme environments, but requires a power system to provide the right amount of energy when an application needs it. Existing systems must provision energy capacity statically based on an application's peak demand which compromises efficiency and responsiveness when not at peak demand. This work presents Capybara: a co-designed hardware/software power system with dynamically reconfigurable energy storage capacity that meets varied application energy demand. The Capybara software interface allows programmers to specify the energy mode of an application task. Capybara's runtime system reconfigures Capybara's hardware energy capacity to match application demand. Capybara also allows a programmer to write reactive application tasks that pre-allocate a burst of energy that it can spend in response to an asynchronous (e.g., external) event. We instantiated Capybara's hardware design in two EH devices and implemented three reactive sensing applications using its software interface. Capybara improves event detection accuracy by 2x-4x over statically-provisioned energy capacity, maintains response latency within 1.5x of a continuously-powered baseline, and enables reactive applications that are intractable with existing power systems.

Measurement of Body Weight Distributions on a Seat Pan for Various Sitting Postures (2012)

Objective: The aims of this study are to develop a body weight distribution measurement system on a seat pan and to find the weight ratios of left and right and posterior and anterior for the ergonomically good or bad postures. Background: During daily work hours, office workers’ sitting postures vary according to the work characteristics, their sitting habit, and chair specifications. To make office workers keep the good sitting postures, a bad posture alarm system can be considered. Results: We developed a body weight distribution measurement system by using four load cells mounted on a seat pan. We also measured the weight distributions for five typical postures. Conclusion: If the left/right weight ratio ranges from 0.8 to 1.2 and posterior/anterior weight ratio from 1.0 to 1.4, the posture can be defined as good balanced posture. Application: The result of this study can be applied to the development of a bad posture alarm system of chair.
Analysis of the instantaneous phase signal of a fMRI time series via the Hilbert transform (2001)

Typically, functional magnetic resonance imaging (fMRI) data is processed in the time domain with linear methods such as regression and correlation analysis. We propose that the theory of phase synchronization may be used to understand the dynamics of interacting systems more completely and can be applied to fMRI data as a novel method of detecting activation. We performed phase synchronization analysis on the data from five volunteers for an event-related finger-tapping task. Functional maps were created that provide information on the interrelations between the instantaneous phases of the reference function and the voxel time series in a whole-brain fMRI activation data set. We conclude that this method of analysis is useful for revealing additional information on the complex nature of the fMRI time series.
Synthesis of (+)-Cladospolide C (2006)

(+)-Cladospolide C was synthesized in eight steps with 5% total yield, using methyl acrylate, (3R,4R)-1,5-hexadiene-3,4-diol, and (6R)-6-hepten-2-ol as the starting materials. Two cross-metathesis reactions and Yamaguchi esterification were applied to assemble the three units into (+)-Cladospolide C. Unsuccessful routes using ring-closing metathesis are also discussed.
Functional and Histological Evaluation following Canine Vocal Fold Reconstruction Using Combined Thyroid Ala Perichondrium Flaps (2014)

Objectives: (1) Perform vocal fold reconstruction using composite thyroid ala perichondrium (CTAP) flaps in beagles following unilateral vocal fold stripping; (2) Evaluate aerodynamic, acoustic, vibratory, and histologic changes in canines undergoing CTAP‐based vocal fold reconstruction compared to a control group undergoing injury alone. Methods: Unilateral vocal fold stripping was performed on ten beagles. Dogs healed for 1 month and were divided into 2 groups. Dogs in the control group (n = 5) were sacrificed. Dogs in the experimental group (n = 5) underwent ipsilateral vocal fold augmentation with a CTAP flap and recovered for 1 month prior to euthanasia. After euthanasia, larynges were harvested for excised larynx evaluation of vocal fold vibration using aerodynamic, acoustic, and mucosal wave measurements. Histological analysis was then performed on anterior, middle, and posterior sections of the vocal fold. Changes in the injured fold were compared between the control and experimental groups. Comparisons with the contralateral normal fold were made within the control and experimental groups. Results: Phonation threshold pressure was significantly lower in the treatment group ( P =. 005). Percentage jitter ( P =. 010) and shimmer ( P =. 007) were also lower in the treatment group. Open quotient was significantly higher in the control group ( P =. 007). Histological staining results were inconsistent, and gross analysis revealed evidence of surgical implantation without restoration of normal vocal fold architecture. Conclusions: CTAP‐based vocal fold augmentation restored glottic closure and vibratory periodicity following vocal fold scarring. Additional investigation on biologic response is warranted. CTAP flaps offer an autologous, vascularized implant that can improve both vocal fold structure and function.
Mixed-Order Finite-Element Modeling of Magnetic Material Degradation Due to Cutting (2018)

As a part of manufacturing of electrical machines, electrical sheets are cut to the desired shape by various cutting techniques, such as punching and laser cutting. This cutting process degrades the magnetic material near the cut edge, which should be included in the finite-element modeling of electrical machines. However, due to the nature of the cutting effects, the existing finite-element modeling of the cutting effect results in computationally heavy simulations. This paper investigates the application of mixed-order elements to model the cutting effect. The second-order nodal triangular elements are used near the cut edge, whereas transition/first-order elements are applied in the remaining solution domain. Furthermore, the accuracy of the presented method is analyzed with the traditional method. According to the simulations, the mixed-order elements returned accurate results significantly faster than the traditional finite-element-based approaches. Furthermore, the effect of the cutting on the machine performance is also studied by comparing its results briefly.

Bäumchen wechsle Dich - Tücken beim automatischen Abgleich hierarchischer Objektstrukturen. (2006)

Die Objektorientierung ist ein in der Softwarebranche seit langem bewahrtes Werkzeug zur Beherrschung von Komplexitat. Dies gilt sowohl fur die interne Architektur der Software selbst als auch fur die dem Nutzer der Software zur Verfugung gestellte Bedienphilosophie und Datenreprasentation. Im Folgenden wird der Begriff der Objektorientierung aus der Sicht des Planers verwendet und fokussiert sich auf objektorientierte Planungstechniken wie Datenreprasentation und -manipulation. Microsoft Visio ist ein Beispiel fur ein bekanntes Zeichenwerkzeug mit objektorientierter Bedienphilosophie. Hier wird eine Zeichnung aus Objekten zusammengesetzt, die ihrerseits durch Eigenschaften und Relationen konfiguriert werden konnen. Planungswerkzeuge wie ComosPT bieten zudem eine komfortable objektorientierte Datenreprasentation in Form hierarchischer Objektbaume [Schul02]. Der Begriff des Objektes wird im Folgenden sowohl fur Objektinstanzen als auch fur Objekttypen verwendet, da sich Typen in einer Typbibliothek wie Objekte verhalten. Der Begriff der Vererbung ist in der Anlagenplanung sowohl auf Klassen (auch als Typen bezeichnet) als auch auf die Instanzbildung anwendbar und erweist sich dort als Schlussel fur effizientes Engineering. Klassenvariablen gelten demzufolge als Eigenschaften von Anlagenobjekten (z. B. „Symbol“) und konnen dort sowohl geandert als auch uberschrieben werden. Das Andern eines Symbols fur alle Instanzen wird so beispielsweise erheblich vereinfacht.
Characterisation of swept-charge devices for the Chandrayaan-1 x-ray spectrometer (C1XS) instrument (2007)

The Indian Space Research Organisation (ISRO) Chandrayaan-1 mission is India's first lunar spacecraft, containing a suite of instruments to carry out high-resolution remote sensing of the Moon at visible, near infrared and X-ray wavelengths. Due for launch in early 2008, the spacecraft will carry out its two year mission in a polar orbit around the Moon at an altitude of 100 km. One of the eleven instruments in the spacecraft payload is the Chandrayaan-1 X-ray Spectrometer (C1XS), a descendant of the successful D-CIXS instrument that flew on the European Space Agency SMART-1 lunar mission launched in 2003. C1XS consists of 24 swept-charge device (SCD) silicon X-ray detectors arranged in 6 modules that will carry out high quality X-ray spectroscopic mapping of the Moon using the technique of X-ray fluorescence. This paper presents an overview of the Chandrayaan-1 mission and specifically the C1XS instrument and describes the development of an SCD test facility, proton irradiation characterisation and screening of candidate SCD devices for the mission.
