Hardware Validation for Control of Three-Phase Grid-Connected Microgrids Using Artificial Neural Networks (2015)

This paper presents a strategy for controlling inverter-interfaced DERs within a microgrid using an artificial neural network. The neural network implements a dynamic programming algorithm and is trained with a new Levenberg-Marquardt backpropagation algorithm. Hardware experiments were conducted to evaluate the performance of the neural network vector control method. They showed that the neural network control technique performs well for DER converter control if the controller output voltage is below the converter?s PWM saturation limit. If the controller?s output voltage exceeds the PWM saturation limit, the neural network controller automatically turns into a state by maintaining a constant dc-link voltage as its first priority, while meeting the reactive power control demand as soon as possible. Under variable, unbalanced, and distorted system conditions, the neural network controller is stable and reliable.
Thermal analysis of laser additive manufacturing of aluminium alloys: Experiment and simulation (2018)

Laser additive manufacturing (LAM) has become increasingly popular in industry in recent decades because it enables exceptional degrees of freedom regarding the structural design of lightweight components compared to subtractive manufacturing techniques. Laser metal deposition (LMD) of wire-fed material shows in particular the advantages such as high process velocity and efficient use of material compared to other LAM processes. During wire-based LMD, the material is deposited onto a substrate and supplemented by successive layers allowing a layer-wise production of complex three-dimensional structures. Despite the increased productivity of LMD, regarding the ability to process aluminium alloys, there is still a lack in quality and reproducibility due to the inhomogeneous temperature distribution during the process, leading to undesired residual stresses, distortions and inconsistent layer geometries and poor microstructures. In this study, the aluminium alloy AA5087 as wire and AA5754 as substrate material were utilized for LMD. In order to obtain information about the temperature field during LMD, thermocouple and thermography measurements were performed during the process. The temperature measurements were used to validate a finite element model regarding the heat distribution, which will be further used to investigate the temperature field evolution over time. To consider the continuous addition of material within the FE-model, an inactive/active element approach was chosen, where initially deactivated elements are activated corresponding to the deposition of material. The first results of the simulation and the experiments show good agreement. Therefore, the model can be used in the future for LMD process optimization, e.g., in terms of minimizing local variations of the thermal load for each layer.
Conclusion (2023)

Summarizes the broad implications of fintech and digital transformation for financial sector policy, monetary policy, and international cooperation. The ongoing transformation of finance represents a paradigm shift, calling for new approaches to regulation and supervision as well as heightened collaboration and cooperation with other public authorities across issues affecting data protection, privacy, and competition. Financial sector and other public authorities will need to step up to this challenge to play a critical role in fostering sound fintech adoption and the development of responsible, open, and inclusive markets for digital finance. The specific needs of individual markets and economies will vary, but looking to underlying technology drivers and economic forces can help policy makers focus their efforts on responding to fundamental changes in financial services rather than to specific product innovations. Addressing these changes comprehensively within any regulatory framework will remain a continuous challenge as markets endlessly innovation and evolve.

The Metrics of Lithography (2010)

In microscopy, one is concerned about the closest distance between two objects that can be resolved in the image. The points of concern are quite different in lithography. A low-contrast image with a shallow-intensity slope can be turned into a sharp edge with the photoresist. As mentioned earlier in Sec. 1.3, the location of this edge is of prime interest and must be quantified against operating parameters of the exposure tool during manufacturing, because it determines the feature size that may be related to circuit-switching speed, leakage, resistance, etc. In addition, the edge position also determines whether the image in a given layer can be effectively overlaid with previous or subsequent layers. The five primary parameters that can be adjusted in the field are exposure dosage, focal position, pattern alignment between layers, magnification, and rotation. The last three parameters are mostly related to overlay. Even though magnification can affect feature size in principle, its effect on overlay is much greater than on feature size. The first two parameters&#x2014;exposure dosage and focal position&#x2014;determine the process window of the lithographic system in a mutually dependent way. This mutual dependence and the ability to superimpose simultaneous requirements on different features are captured in the exposuredefocus (E-D) tools that are the backbone of lithography metrics. 4.1 The Resolution and DOF Scaling Equations Section 2.2 introduced resolution and DOF scaling in projection printing using the proportional relationship to wavelength and inverse proportional relationship to the lens NA without introducing the proportional constant. Equations (3.9) and (3.13) used an arbitrary constant of 0.5 as we provided the physical meaning of these relationships. Here, we finally introduce the resolution and DOF scaling equation with the rigorous proportional constants <i>k</i><sub>1</sub> and <i>k</i><sub>3</sub>. We wait until now to do so, because the E-D tools discussed in this chapter can unambiguously determine these proportional constants.

Slowing the oxidation of Cu in Cu–Co nanocrystals by Co surface passivation (1995)

Heating chemically prepared nanocrystals of Cu80Co20 causes Co to precipitate preferentially on the surface of the Cu nanocrystals. X-ray diffraction and x-ray photoelectron spectroscopies show that the Co significantly retards the oxidation of the Cu nanocrystals.
In-vivo Z-spectra acquisition with decreased direct saturation using adiabatic spin-lock pulses at 9.4T (2018)

Off-resonant spin-lock imaging enables a lot of possibilities for T1ρ and chemical exchange (CE) sensitive applications. For this purpose, a matching amplitude of the tipping and the locking pulse is required, which can be difficult due to the high power requirements of adiabatic pulses. In this work, we present a newly shaped adiabatic half-passage pulse, usable at low power to match the amplitude of the pulses. Off- and on-resonant saturated images acquired at 9.4T are shown. The new pulse shape is able to generate robust images with comparatively low power at ultra-high-field strengths.
Co-delivery of rapamycin- and piperine-loaded polymeric nanoparticles for breast cancer treatment (2015)

P-glycoprotein (P-gp) efflux is the major cause of multidrug resistance (MDR) in tumors when using anticancer drugs, moreover, poor bioavailability of few drugs is also due to P-gp efflux in the gut. Rapamycin (RPM) is in the clinical trials for breast cancer treatment, but its P-gp substrate property leads to poor oral bioavailability and efficacy. The objective of this study is to formulate and evaluate nanoparticles of RPM, along with a chemosensitizer (piperine, PIP) for improved oral bioavailability and efficacy. Poly(d,l-lactide-co-glycolide) (PLGA) was selected as polymer as it has moderate MDR reversal activity, which may provide additional benefits. The nanoprecipitation method was used to prepare PLGA nanoparticles with particle size below 150 nm, loaded with both drugs (RPM and PIP). Prepared nanoparticles showed sustained in vitro drug release for weeks, with initial release kinetics of zero order with non-Fickian transport, subsequently followed by Higuchi kinetics with Fickian diffusion. An everted gut sac method was used to study the effect of P-gp efflux on drug transport. This reveals that the uptake of the RPM (P-gp substrate) has been increased in the presence of chemosensitizer. Pharmacokinetic studies showed better absorption profile of RPM from polymeric nanoparticles compared to its suspension counterpart and improved bioavailability of 4.8-folds in combination with a chemosensitizer. An in vitro cell line study indicates higher efficacy of nanoparticles compared to free drug solution. Results suggest that the use of a combination of PIP with RPM nanoparticles would be a promising approach in the treatment of breast cancer.
Wideband Endfire On-Glass Array for 5G Handset Applications (2019)

A wideband endfire array considering the glass influence at 28 GHz is proposed in this paper. The array element is a bow-tie slot antenna above a ground plane, which has the endfire radiation pattern. A glass layer, which has the same size as the ground plane, is attached on the front side of the array. A trapezoid slot is made on the edge of the ground plane to compensate the influence of the glass layer. The simulated -10dB bandwidth is 11.3% from 25 GHz to 28 GHz and -6-dB bandwidth is 30.3% from 21 GHz to 28.5 GHz. The horizontal polarized endfire gain of the 4 element array ranges from 7.08 dBi to 8.36 dBi over the operating band. The array covers from -100° to 100°, when the realized gain is above 0 dBi on the XOY plane.
Polymer-based passive and active guided-wave devices and their applications (1993)

Due to the material property restrictions of LiNb0<sub>3</sub> and III-V compound material systems a sizable portion of the research work on guided wave devices has been shifted to polymer-based materials. Low material dispersion, flexible material preparation process, unlimited device size and cost effectiveness are the major factors that can not be provided using conventional inorganic materials. By definition, polymer matrix is formed by linking an array of monomers. Therefore, there are infinite number of polymeric materials can be generated. The Polymeric materials suitable for guided wave device research are the ones with desired optical and electrooptic properties. In this paper, we report the research status of the photolime gel superpolymer. In contrast to any artificial polymer that are synthesized according to a predesigned formula, the polymer we employed is a class of biopolymer which consists of thousands of 1 to 2 nmlong amino acids. A myriad of passive and active guided wave devices has been successfully fabricated using the photolime gel polymer. These include high density linear and curved channel waveguide arrays, electrooptic modulator and modulator array, highly multiplexed waveguide holograms for wavelength division demultiplexing and optical interconnects, waveguide lens, and rare earth ion doped polymer waveguide amplifier. A single-mode linear channel waveguide array with device packaging density of 1250 channels/cm is achieved. The first 12-channel wavelength division demultiplexer working at 830, 840, 850, 860, 870, 880, 890, 900, 910, 920, 930, and 940nm on a GaAs substrate is also described in this paper. A polymer-based electrooptic traveling wave modulator with 40 GHz electrical bandwidth is further delineated. A rare earth ion doped polymer waveguide amplifier working at 1.06pm with 8.5dB optical gain is also achieved using this polymer matrix. The tunability of the waveguide refractive index allows the formation of a graded index (GRIN) layer. As a result, these active and passive guided wave devices can be realized on any substrate of interest. High quality waveguide (loss&lt;0.1dB/cm) has been made on Glass, LiNb0<sub>3</sub>, Fused Silica, Quartz, PC board, GaAs, Si, Al, Cu, Cr, Au, Kovar, BeO, AI<sub>2</sub>O<sub>3</sub> and AIN.
A New Compensation Method for Emission Degradation in an AMOLED Display Via an External Algorithm, New Pixel Circuit, and Models of Prior Measurements (2014)

A new external algorithm with sensing circuit are proposed to compensate AMOLED display degradation. The compensation is enabled by first evaluating degradation level of OLEDs based on the OLED anode voltages detected by a newly-designed sensing subcircuit. According to sensed voltages, the external algorithm selects appropriate built-in models to compensate OLED degradation with the aim to achieve expected OLED emitted luminance. The models are established based on prior measurements to prescribe the relations between luminance and current (L-I) and luminance and voltage (L-V) of each OLED. In this way of compensation, the proposed method is able to incorporate negative effects of OLED degradation aggravation while increasing driving current to compensate the original decay in OLED luminance. Moreover, another algorithm along with the 4T0.5C pixel circuit as presented in prior studies are adopted to compensate process variation in Vth among pixels for improving the emission uniformity of an AMOLED panel. Experiments are conducted by combining the external algorithm with sensing circuit and the pixel circuit to validate the performances of compensating and alleviating OLED degradation.

Pharmacologic efficacy of PU.1 inhibition by heterocyclic dications: a mechanistic analysis (2016)

Heterocyclic dications are receiving increasing attention as targeted inhibitors of transcription factors. While many dications act as purely competitive inhibitors, some fail to displace protein efficiently at drug concentrations expected to saturate their DNA target. To achieve a mechanistic understanding of these non-competitive effects, we used a combination of dications, which are intrinsically fluorescent and spectrally-separated fluorescently labeled DNA to dissect complex interactions in multi-component drug/DNA/protein systems. Specifically, we interrogated site-specific binding by the transcription factor PU.1 and its perturbation by DB270, a furan-bisbenzimidazole-diamidine that strongly targets PU.1 binding sites yet poorly inhibits PU.1/DNA complexes. By titrating DB270 and/or cyanine-labeled DNA with protein or unlabeled DNA, and following the changes in their fluorescence polarization, we found direct evidence that DB270 bound protein independently of their mutual affinities for sequence-specific DNA. Each of the three species competed for the other two, and this interplay of mutually dependent equilibria abrogated DB270's inhibitory activity, which was substantively restored under conditions that attenuated DB270/PU.1 binding. PU.1 binding was consistent with DB270's poor inhibitory efficacy of PU.1 in vivo, while its isosteric selenophene analog (DB1976), which did not bind PU.1 and strongly inhibited the PU.1/DNA complex in vitro, fully antagonized PU.1-dependent transactivation in vivo.
An optical feed for high resolution passive millimetre wave imaging systems (1992)

The authors discuss two methods to improve the spatial resolution of millimetre wave imagers. One employs a large primary aperture, a 1.4 m square primary reflector, and the other enhances the resulting images using superresolution techniques. These later techniques effectively boost the high spatial frequency content in the image, thereby sharpening the perceived antenna far field pattern. It is usual in radar applications to taper the primary aperture distribution in order to suppress sidelobes. Such a distribution if used in millimetre wave imaging would result in a loss of the high spatial frequencies required by the superresolution algorithms. In the first section they show why a rectangular aperture distribution is preferred and how this can be achieved by relaying a uniform feed distribution onto the primary reflector using millimetre wave optics. Such relaying techniques have been demonstrated on their 35 GHz imaging system and the resulting imagery is illustrated in the final section.

Differentiation between genetic mutations of breast cancer by breath volatolomics (2015)

Mapping molecular sub-types in breast cancer (BC) tumours is a rapidly evolving area due to growing interest in, for example, targeted therapy and screening high-risk populations for early diagnosis. We report a new concept for profiling BC molecular sub-types based on volatile organic compounds (VOCs). For this purpose, breath samples were collected from 276 female volunteers, including healthy, benign conditions, ductal carcinoma in situ (DCIS) and malignant lesions. Breath samples were analysed by gas chromatography mass spectrometry (GC-MS) and artificially intelligent nanoarray technology. Applying the non-parametric Wilcoxon/Kruskal-Wallis test, GC-MS analysis found 23 compounds that were significantly different (p < 0.05) in breath samples of BC patients with different molecular sub-types. Discriminant function analysis (DFA) of the nanoarray identified unique volatolomic signatures between cancer and non-cancer cases (83% accuracy in blind testing), and for the different molecular sub-types with accuracies ranging from 82 to 87%, sensitivities of 81 to 88% and specificities of 76 to 96% in leave-one-out cross-validation. These results demonstrate the presence of detectable breath VOC patterns for accurately profiling molecular sub-types in BC, either through specific compound identification by GC-MS or by volatolomic signatures obtained through statistical analysis of the artificially intelligent nanoarray responses.
