Achieving the quantum field theory limit in far-from-equilibrium quantum link models (2022)

Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along with potential applications in quantum information and science technologies. In light of the impressive ongoing efforts to achieve such realizations, a fundamental question regarding quantum link model regularizations of lattice gauge theories is how faithfully they capture the quantum field theory limit of gauge theories. Recent work \cite{zache2021achieving} has shown through analytic derivations, exact diagonalization, and infinite matrix product state calculations that the low-energy physics of <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mn>1</mml:mn><mml:mo>+</mml:mo><mml:mn>1</mml:mn></mml:math>D <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow class="MJX-TeXAtom-ORD"><mml:mi mathvariant="normal">U</mml:mi></mml:mrow><mml:mo stretchy="false">(</mml:mo><mml:mn>1</mml:mn><mml:mo stretchy="false">)</mml:mo></mml:math> quantum link models approaches the quantum field theory limit already at small link spin length <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi>S</mml:mi></mml:math>. Here, we show that the approach to this limit also lends itself to the far-from-equilibrium quench dynamics of lattice gauge theories, as demonstrated by our numerical simulations of the Loschmidt return rate and the chiral condensate in infinite matrix product states, which work directly in the thermodynamic limit. Similar to our findings in equilibrium that show a distinct behavior between half-integer and integer link spin lengths, we find that criticality emerging in the Loschmidt return rate is fundamentally different between half-integer and integer spin quantum link models in the regime of strong electric-field coupling. Our results further affirm that state-of-the-art finite-size ultracold-atom and NISQ-device implementations of quantum link lattice gauge theories have the real potential to simulate their quantum field theory limit even in the far-from-equilibrium regime.
Cyanamide-Induced Granulocytopenia. (1997)

We report a 64-year-old male with granulocytopenia and dermatitis due to cyanamide treatment. We administered cyanamide for alcoholism. After about one month he suffered from scaly erythema over his whole body and granulocytopenia (granulocyte; 140/microliter) with maturation arrest in bone marrow. After cessation of cyanamide and the start of granulocyte colony-stimulating factor administration, the skin eruption ameliorated gradually, and the peripheral blood granulocyte counts increased. Cyanamide showed positive results in the drug lymphocyte stimulation test (198%) and the patch test led to the diagnosis of granulocytopenia and dermatitis induced by cyanamide. After restarting glibenclamide and diazepam administration, his granulocytopenia did not reoccur. To our knowledge, this is the first report of a case with granulocytopenia induced by cyanamide.
Additional Notes on Finite Element Models of Deformable Featureless Headform (1997)

&lt;div class="htmlview paragraph"&gt;Model characteristics of a finite element deformable featureless headform with one to four layers of solid elements for the headform skin are studied using both the LS-DYNA3D and FCRASH codes. The models use a viscoelastic material law whose constitutive parameters are established through comparisons of drop test simulations at various impact velocities with the test data. Results indicate that the one-layer model has a significant distinct characteristic from the other (2-to-4-layer) models, thus requiring different parametric values. Similar observation is also noticed in simulating drop tests with one and two layers of solid elements for the headform skin using PAM-CRASH. When using the same parametric values for the viscoelastic material, both the LS-DYNA3D and FCRASH simulations yield the same results under identical impact conditions and, thereby, exhibit a “functional equivalency” between these two codes.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;In addition, the effects of viscoelastic parameters on the headform responses are studied. Further utilization of these models in upper vehicle interior structural simulations yields comparable results regardless of which deformable featureless headform (i.e. 1- to 4-layer models) is used as an impactor.&lt;/div&gt;

Novel Multirate Modulator for High-Bandwidth Multicell Converters (2020)

The series and parallel multicell converters have been introduced because they provide benefits in terms of efficiency and power density. However, they also allow reducing the amount of energy stored in the filters, which potentially allows for faster dynamic responses. Interleaving the control patterns of different cells is another distinctive feature of these converters and is also the root of another potential improvement of the dynamic response: with one pulsewidth modulation (PWM) update at each subcycle of the switching period, the n-cell converter may change its average output voltage over each of these intervals, while standard converters can only control the voltage over half the switching period. In this article, a general multirate modulation strategy taking advantage of this property, while avoiding an overswitching, and compatible with any n-cell converter is proposed and validated by simulation and experimental results.

Insulin and polycystic ovary syndrome: A new look at an old subject (1998)

In recent years the metabolic implications of polycystic ovary syndrome (PCOS) have received a great deal of attention; in fact 50% of women with PCOS are obese and a similar percentage of subjects was found to show exaggerated insulin secretion and reduced insulin-stimulated glucose uptake. The presence of these features in women with PCOS has profound clinical implications in terms of morbidity due to diabetes mellitus, dsylipidemia, hypertension and cardiovascular disease. Moreover, hyperinsulinemia has recently been proposed as a possible independent risk factor for endometrial and breast cancer. In the light of these considerations, the importance of metabolic screening in patients with PCOS in order to improve their quality of life cannot be underestimated. In this review we analyze all the clinical pathologies in which hyperinsulinemia of PCOS could be involved. Furthermore, in order to clarify the possible mechanisms leading to the insulin disorders of the syndrome, we review the available data about the insulin receptor abnormalities, as well as those concerning the insulin resistance and the exaggerated insulin secretion. Finally, we examine the main therapeutic strategies to ameliorate the insulinemic status of PCOS patients in order to potentially be able to prevent the long-term consequences of this syndrome.
Robust and Scalable Differentiable Neural Computer for Question Answering (2018)

Deep learning models are often not easily adaptable to new tasks and require task-specific adjustments. The differentiable neural computer (DNC), a memoryaugmented neural network, is designed as a general problem solver which can be used in a wide range of tasks. But in reality, it is hard to apply this model to new tasks. We analyze the DNC and identify possible improvements within the application of question answering. This motivates a more robust and scalable DNC (rsDNC). The objective precondition is to keep the general character of this model intact while making its application more reliable and speeding up its required training time. The rsDNC is distinguished by a more robust training, a slim memory unit and a bidirectional architecture. We not only achieve new state-of-the-art performance on the bAbI task, but also minimize the performance variance between different initializations. Furthermore, we demonstrate the simplified applicability of the rsDNC to new tasks with passable results on the CNN RC task without adaptions.

Studies on analgesic oligopeptides. II. Structure-activity relationship among thirty analogs of a cyclic dipeptide, cyclo(-Tyr-Arg-) (1982)

Thirty diketopiperazines were synthesized as analogs of cyclo (-Tyr-Arg-). The analgesic activities of these analogs were evaluated after intracerebral administration in mice. In the cyclo (-X-Arg-) series of analogs, cyclo [-Tyr (Et)-Arg-] showed the most potent activity. In the cyclo (-Tyr-Y-) series of analogs, the activity decreased in the order Y=homoarginine, p-guanidinophenylalanine, 2-amino-4-guanidinobutyric acid, Lys, Orn, His, α, γ-diaminobutyric acid and Pro. Among the analogs synthesized, cyclo-[-Tyr (Et)-Har-], which was designed on the basis of the above results, exhibited remarkably potent analgesic activity, being 17 times more potent than cyclo (-Tyr-Arg-) and nearly as potent as morphine on a molar basis. The structure-activity relation of cyclo(-Tyr-Arg-) is discussed in the light of these results.
Influence of ZnO Co-Doping On the Structural, Optical, and Antibacterial Properties of (Zn1-2xcexfex) O Nanoparticles (2015)

Pure and co-doped ZnO nanoparticles were synthesized by microwave combustion method using urea as a fuel. Structural, optical, morphological and magnetic property was studied using X-ray diffraction (XRD), scanning electron microscopy (SEM), diffuse reflectance spectroscopy (DRS), and photoluminescence (PL) spectra. X-ray diffraction measurements of the nanoparticles showed the same wurtzite hexagonal structure and preferential orientation along the c-axis. The scanning electron microscope image of the nanoparticles revealed an average particle size of 47-23 nm. The calculated results from DRS spectroscopy indicated that the band gap of the synthesized samples decreased with the increment of the concentration of co-dopant, which resulted in the red-shift. The photoluminescence (PL) studies revealed that violet, blue and green emissions. The well diffusion method was used for antibacterial activities of two Gram negative and three Gram positive bacterial pathogens. The doping with Ce and Fe by microwave method improves the antibacterial property.
Role of Auxin-Induced Reactive Oxygen Species in Root Gravitropism (2001)

We report our studies on root gravitropism indicating that reactive oxygen species (ROS) may function as a downstream component in auxin-mediated signal transduction. A transient increase in the intracellular concentration of ROS in the convex endodermis resulted from either gravistimulation or unilateral application of auxin to vertical roots. Root bending was also brought about by unilateral application of ROS to vertical roots pretreated with the auxin transport inhibitor N-1-naphthylphthalamic acid. Furthermore, the scavenging of ROS by antioxidants (N-acetylcysteine, ascorbic acid, and Trolox) inhibited root gravitropism. These results indicate that the generation of ROS plays a role in root gravitropism.
A Radiative Transfer Model for Climate Calculations (2000)

This paper describes a radiative transfer model developed to accurately predict the atmospheric radiant flux in both the infrared and the solar spectrum with a minimum of computational effort. We use a newly developed k-distribution model for both the thermal and solar parts of the spectrum. We employ a generalized two-stream approximation for the scattering by aerosol and clouds. To assess the accuracy of the model, the results are compared to other more detailed models for several standard cases in the solar and thermal spectrum. We perform several calculations focussing primarily on the question of absorption of solar radiation by gases and aerosols. We estimate the accuracy of the k-distribution to be approx. 1 W/sq m for the gaseous absorption in the solar spectrum. We estimate the accuracy of the two-stream method to be 3-12 W/sq m for the downward solar flux and 1-5 W/sq m for the upward solar flux at the top of atmosphere depending on the optical depth of the aerosol layer. We also show that the effect of ignoring aerosol absorption on the downward solar flux at the surface is 50 W/sq m for the TARFOX aerosol for an optical depth of 0.5 and 150 W/sq m for a highly absorbing mineral aerosol. Thus, we conclude that the uncertainty introduced by the aerosol solar radiative properties (and merely assuming some representative model) can be considerably larger than the error introduced by the use of a two-stream method.

Application of Static Var Compensator (SVC) with fuzzy controller for grid integration of wind farm (2010)

Large-scale integration of wind turbine generators (WTGs) may have significant impacts on power system operation with respect to bus voltages, system frequency, etc. Voltage control and reactive power compensation in a weak distribution network for integration of wind power represents the main concern of this paper. Without reactive power compensation, the integration of wind power in a network may potentially cause voltage collapse in the system and under-voltage tripping of wind power generators. This paper shows that while static compensation (Fixed Capacitor Bank) is unable to prevent voltage collapse, dynamic reactive power compensation using Static Var Compensator (SVC) at the a point of interconnection of wind farm is successful in maintaining acceptable voltage level. Moreover, this paper shows that by using a fuzzy controller instead of a PI controller, the performance of SVC is improved. MATLAB/Simulink based simulation is utilized to demonstrate the application of SVC in wind farm integration and the enhancement in performance achieved with a fuzzy controller as compared to a Proportional Integral controller for voltage regulation during fault scenarios.
Speech mining in noisy audio message corpus (2007)

Within the framework of automatic analysis of spoken telephone surveys we propose a robust Speech Mining strategy that selects, from a large database of spoken messages, the ones likely to be correctly processed by the Automatic Speech Recognition and Classification processes. The problem considered in this paper is the analysis of messages uttered by the users of a telephone service in response to a recorded message that asks if a problem they had was satisfactorily solved. Very often in these cases, subjective information is combined with factual information. The purpose of this type of analysis is the extraction of the distribution of users opinions. Therefore it is very important to check the representativeness of the subset of messages kept by the rejection strategies. Several measures, based on the Kullback-Leibler divergence, are proposed in order to evaluate the correctness of the information extracted as well as its representativeness .
Data tiering in heterogeneous memory systems (2016)

Memory-based data center applications require increasingly large memory capacities, but face the challenges posed by the inherent difficulties in scaling DRAM and also the cost of DRAM. Future systems are attempting to address these demands with heterogeneous memory architectures coupling DRAM with high capacity, low cost, but also lower performance, non-volatile memories (NVM) such as PCM and RRAM. A key usage model intended for NVM is as cheaper high capacity volatile memory. Data center operators are bound to ask whether this model for the usage of NVM to replace the majority of DRAM memory leads to a large slowdown in their applications? It is crucial to answer this question because a large performance impact will be an impediment to the adoption of such systems.
Characterization of Glass Surface. I. Mechanisms of Various Surface-Related Phenomena on Glass. (2001)

This paper is concerned with the mechanisms of various surface-related phenomena on glass and the analytical techniques suitable for the study. As a phenomenon with respect to optical properties of glass surface, the mechanisms of optically dimming phenomenon caused by interaction with the environment, namely weathering resistance of the glass, are explained on the basis of changes in the surface layer composition. Furthermore, as a phenomenon with respect to chemical reactivity of glass surface, factors governing the adsorption property of float glass as the majority of flat glass have been discussed extensively in terms of the surface OH group as an adsorptive site, including the SnOH group originated from tin penetration into the glass during a float process. Additionally, a typical contamination substance on glass surface and a newly developed technique for the removal of them are introduced. In these practical examples, the applications of advanced surface analytical techniques such as SIMS have been mentioned to characterize successfully the glass surface, and it may contribute to the development of highly efficient glass applications.
Ion Mobility-Mass Spectrometry with a Radial Opposed Migration Ion and Aerosol Classifier (ROMIAC) (2013)

The first application of a novel differential mobility analyzer, the radial opposed migration ion and aerosol classifier (ROMIAC), is demonstrated. The ROMIAC uses antiparallel forces from an electric field and a cross-flow gas to both scan ion mobilities and continuously transmit target mobility ions with 100% duty cycle. In the ROMIAC, diffusive losses are minimized, and resolution of ions, with collisional cross-sections of 200-2000 Å(2), is achieved near the nondispersive resolution of ~20. Higher resolution is theoretically possible with greater cross-flow rates. The ROMIAC was coupled to a linear trap quadrupole mass spectrometer and used to classify electrosprayed C2-C12 tetra-alkyl ammonium ions, bradykinin, angiotensin I, angiotensin II, bovine ubiquitin, and two pairs of model peptide isomers. Instrument and mobility calibrations of the ROMIAC show that it exhibits linear responses to changes in electrode potential, making the ROMIAC suitable for mobility and cross-section measurements. The high resolution of the ROMIAC facilitates separation of isobaric isomeric peptides. Monitoring distinct dissociation pathways associated with peptide isomers fully resolves overlapping peaks in the ion mobility data. The ability of the ROMIAC to operate at atmospheric pressure and serve as a front-end analyzer to continuously transmit ions with a particular mobility facilitates extensive studies of target molecules using a variety of mass spectrometric methods.
Crossover of high-energy spin fluctuations from collective triplons to localized magnetic excitations in Sr14−xCaxCu24O41 ladders (2022)

Abstract We studied the magnetic excitations in the quasi-one-dimensional (q-1D) ladder subsystem of Sr 14−x Ca x Cu 24 O 41 (SCCO) using Cu L 3 -edge resonant inelastic X-ray scattering (RIXS). By comparing momentum-resolved RIXS spectra with high ( x = 12.2) and without ( x = 0) Ca content, we track the evolution of the magnetic excitations from collective two-triplon (2 T) excitations ( x = 0) to weakly-dispersive gapped modes at an energy of 280 meV ( x = 12.2). Density matrix renormalization group (DMRG) calculations of the RIXS response in the doped ladders suggest that the flat magnetic dispersion and damped excitation profile observed at x = 12.2 originates from enhanced hole localization. This interpretation is supported by polarization-dependent RIXS measurements, where we disentangle the spin-conserving Δ S = 0 scattering from the predominant Δ S = 1 spin-flip signal in the RIXS spectra. The results show that the low-energy weight in the Δ S = 0 channel is depleted when Sr is replaced by Ca, consistent with a reduced carrier mobility. Our results demonstrate that off-ladder impurities can affect both the low-energy magnetic excitations and superconducting correlations in the CuO 4 plaquettes. Finally, our study characterizes the magnetic and charge fluctuations in the phase from which superconductivity emerges in SCCO at elevated pressures.
Electron inelastic plasmon scattering and its resonance propagation at crystal surfaces in RHEED (1989)

The modified multislice theory [Wang (1989). Acta Cryst. A45, 193-199] has been employed to calculate the electron reflection intensity with and without considering the plasmon diffuse scattering in the geometry of reflection high-energy electron diffraction (RHEED). It has been shown that the inelastic scattering can greatly enhance the reflectance of a surface, depending critically on the incident conditions of the electrons. At some incidences, the inelastic resonance reflection is enhanced, which is considered as the 'true' surface resonance state. This happens within a very narrow angular range (<1 mrad). For 'true' resonance states, the inelastic intensity is much stronger than for other conditions as shown both theoretically and experimentally. The enhancement of the reflection intensity may not be the proper criterion for identifying the 'true' surface resonance. Besides the surface plasmon peaks, an 'extra' peak, located at 4.5 eV, is observed in the reflection electron energy-loss spectroscopy (REELS) study of the 'true' resonance of GaAs (110) surface. This is considered as a characteristic of the resonance propagations of the electrons along the surface and may result from the generation of resonance radiation.
