24·5% Efficiency silicon PERT cells on MCZ substrates and 24·7% efficiency PERL cells on FZ substrates

This paper reports the recent improvements in the energy conversion efficiencies of solar cells on magnetically-confined Czochralski grown (MCZ) and float zone (FZ) silicon substrates at the University of New South Wales. A PERT (passivated emitter, rear totally-diffused) cell structure has been used to reduce the cell series resistance from higher resistivity substrates. The total rear boron diffusion in this PERT structure appears to improve the surface passivation quality of MCZ and some FZ substrates. Hence, higher open-circuit voltages were observed for some PERT cells. One of these cells on MCZ substrates demonstrated 24·5% energy conversion efficiency at Sandia National Laboratories under the standard global spectrum (100 mW/cm2) at 25°C. This is the highest efficiency ever reported for a MCZ silicon solar cell. The cells made on MCZ substrates also showed stable cell performance rather than the usually reported unstable performance for boron-doped CZ substrates. Also reported is a PERL (passivated emitter, rear locally-diffused) cell on a FZ substrate of 24·7% efficiency, which is the highest efficiency ever reported for any silicon solar cell.

CHANGES IN THE INTERNATIONAL NETWORK OF JAPANESE ELECTRONICS MANUFACTURERS

The purpose of this research is to compare and analyse the actual selection of the area where a Japanese company expands overseas in the electrical industry and the influence on the business results of each individual company. The first purpose of this research is macro analysis, where the aim is to understand and consider the decision-making of Japanese electronics manufacturers as ‘collective intelligence’ about the trend of locations where the bases are deployed as a whole. The second purpose of this research is a microscopic analysis of the influence of the choice of overseas base development on the business performance of individual companies. The influence of the degree of fitness between strategy and organization on companies’ competitive advantage and profitability was focused. As a research methodology, a database was constructed and analysed regarding actual overseas expansion trends of companies. As a result of macro analysis, compared with the rapid changes in the global economic environment, the actual situation of overseas expansion of Japanese electronics manufacturers has not changed much from the past, and it will be a challenge for Japanese companies. As a result of a micro analysis, a model was verified that showed the optimal choices for overseas expansion through indicators related to the strategy, such as the degree of vertical integration and diversification of companies.
Values of fibrinogen in relation to segmental involvement of the venous system in patients with recurrent deep vein thrombosis

Introduction: The occurrence of recurrent venous thrombosis, despite adequate therapy, is still a topic of research in the scientific world. The site of thrombosis and the involvement of anatomical segments represent a significant factor in its occurrence. Aim: To correlate fibrinogen values with anatomical location and extent of verified thrombus in patients with recurrent deep vein thrombosis. Materials and methods: In the period January 2007-January 2020, 223 patients with recurrent deep vein thrombosis were analyzed. At admission fibrinogen values were taken. Results: There was no significant difference in fibrinogen values in relation to gender (p = 0.842). The difference in mean fibronogen values between proximal (n = 171) and distal (n = 27 = veins) were not statistically significant (p = 0.326). There was no difference between the average values of fibrinogen in relation to the number of segments (1 to 3) (p = 0.298). The largest number of patients (n = 132) had 2 segments affected, and fibrinogen values was 4.7 g/L (3.6-7.1 g/L). Male gender had slightly higher fibrinogen values than females, but without significance (p = 0.091). The age of the subjects did not correlate with fibrinogen values ( p = 0.569). Fibrinogen values according to vein anatomical localization were statistically non-significant (p = 0.201). Conclusion: Fibrinogen values were not proved to be an indicator of anatomical localization and segmental involvement in patients with recurrent DVT. Keywords: fibrinogen, venous thrombosis, prognosis.

Determinizing Crash Behavior with a Verified Snapshot-Consistent Flash Translation Layer

This paper introduces the design of a snapshot-consistent flash translation layer (SCFTL) for flash disks, which has a stronger guarantee about the possible behavior after a crash than conventional designs. More specifically, the flush operation of SCFTL also has the functionality of making a “disk snapshot. ” When a crash occurs, the flash disk is guaranteed to recover to the state right before the last flush. The major benefit of SCFTL is that it allows a more efficient design of upper layers in the storage stack. For example, the file system built on SCFTL does not require the use of a journal for crash recovery. Instead, it only needs to perform a flush operation of SCFTL at the end of each atomic transaction. We use a combination of a proof assistant, a symbolic executor, and an SMT solver, to formally verify the correctness of our SCFTL implementation. We modify the xv6 file system to support group commit and utilize SCFTL’s stronger crash guarantee. Our evaluation using file system benchmarks shows that the modified xv6 on SCFTL is 3 to 30 times faster than xv6 with logging on conventional FTLs, and is in the worst case only two times slower than the state-of-the-art setting: the ext4 file system on the Physical Block Device (pblk) FTL.
Variants of the Sliding Mode Control in Presence of External Disturbance for Quadrotor

In this paper, an Improved Integral Power Rate Exponential Reaching Law (IIPRERL) Sliding Mode Control strategy has been presented to cater to the chattering problem and stability issue with the focusing on to achieve minimum steady-state errors in the presence of matched disturbances for a quadrotor. Control strategies have been implemented on quadrotor which is 6 Degree of Freedom (DOF) underactuated model and it is derived via Newton-Euler(NE) equations. The main focus of this article is to design two flight control strategies for a quadrotor. Firstly, a novel IIPRERL-SMC is designed through Improved Integral Sliding Mode Control (II-SMC) via proper gain scheduling by system Eigenvalues. The control objective is to construct a controller such that would force the state trajectories to approach the sliding surface with an exponential policy. Meanwhile, a strong condition for reaching the law of sliding surface via Hurwitz stability has been introduced to the hovering of the quadrotor. Secondly, kinodynamic Rapidly Exploring Random Tree with Fixed Node (RRT*FN) which is an incremental sampling-based optimal algorithm has been implemented for online navigation and flight control of the quadrotor system. Online planning which is based on the offline one, is given on-board radar readings which gradually produces a smooth 3-D trajectory aiming at reaching a predetermined target in an unknown environment. The performance and stability of the quadrotor are completely examined by utilizing Lyapunov stability analysis. Simulations are presented to verify that the proposed scheme is effective with Hurwitz stability for both translational and rotational parts of the quadrotor.
Swelling Degree of Cellulose Materials and Hydrolysis Rate with Cellulase

We investigated some relationships between the hydrolysis rate with cellulase and the swelling degree of the cellulose fibers of different samples. The water retention value (WRV) determined by the centrifugal method was used as a measure of the swelling degree. A linear relationship was observed between the hydrolysis rate and the WRV of the untreated pulps of different chemical composition and crystallinity. A similar linearity was observed also for pulps treated mechanically or chemically, but the slope of the regression line differed with the treating methods, and it decreased in proportion with the degree of degradation of the fiber structure.
An Incentive Mechanism for Building a Secure Blockchain-Based Internet of Things

The world-changing blockchain technique provides a novel method to establish a secure, trusted, and decentralized system for solving the security and personal privacy problems in the Internet of Things (IoT) applications. As the mining process in blockchain requires high computational power, the lightweight IoT devices need to purchase computational resources from edge servers and thus can offload their computational tasks. The amount of computational resource purchased by IoT devices depends on how many profits they can get in the mining process, and will directly affect the security of the blockchain network. The security of the blockchain is closely related to the profits of the blockchain platform. Actually, there is a trade-off between blockchain security and the profits of the blockchain platform. In this paper, we investigate the incentive mechanism for the blockchain platform to attract IoT devices to purchase more computational power from edge servers to participate in the mining process, thereby building a secure blockchain network while guaranteeing the profits of the blockchain platform. We model the interaction between the blockchain platform and IoT devices as a two-stage Stackelberg game, where the blockchain platform act as the leader, and IoT devices act as followers. We analyze the existence and uniqueness of the Stackelberg equilibrium, and propose an efficient algorithm to compute the Stackelberg equilibrium point. Furthermore, we evaluate the performance of our algorithm through extensive simulations, and analyze the strategies of the blockchain platform and IoT devices under different situations.
A Sensorless Model-Based Digital Driving Scheme for Synchronous Rectification in 1-kV Input 1-MHz GaN LLC Converters

For 1-MHz GaN LLC converters with 1-kV input, the switching speed of eGaN high-electron mobility transistors (HEMTs) is as fast as 6 ns, which results in dv/dt up to 200 kV/μs. It poses serious challenge for synchronous rectification (SR). A sensorless model-based SR driving scheme for high voltage applications is proposed to optimize the efficiency at steady state and the complementary control as an interlock mechanism is applied during the transients to ensure safety. A mathematic model is built to determine the turn-on instant and conduction time related to the switching frequency and load condition so that the driving signals are adjusted adaptively. The proposed method provides reliable gate driving signals without any detection circuits and is immune to high frequency noise. The transient response is analyzed and the tolerance effects of the resonant components are analyzed quantitatively. This control is fully transparent to design engineers compared to SR drive ICs, and is convenient to implement in high voltage and high frequency applications. A 1-MHz prototype with 1-kV input and 32 V/3 kW output is built, which achieves the power density of 103 W/in3 and peak efficiency of 95.92% with an improvement of 2.0% at full load compared to the conventional SR driving scheme.
A Proton Magnetic Resonance Study of the Ultraviolet Photoproduct of d(TpT) in Aqueous Solution

The p.m. r. data of d(TpT) and its predominant u.v. photoproduct d(T[p]T) in aqueous solution are compared. The data are consistent with the presence of a cis-syn cyclobutane ring in d(T[p]T). Consideration of the H1′ chemical shifts leads to the conclusion that changes in the sugar–base torsion angle of both nucleotide fragments of the parent molecule are required to bring the thymine bases into alignment for photodimerization. The coupling constants indicate that the conformation of the 5′-terminal fragment is only slightly affected by the cyclobutane ring formation. Photodimerization brings about a distortion of the sugar pucker in the 3′-terminal fragment. In this fragment both the gauche-gauche and gauche-trans conformers are significantly populated whereas the trans-gauche form is excluded.
Submicron Particles of Reversed Lipid Phases in Water Stabilized by a Nonionic Amphiphilic Polymer

The present study concerns the formation and structure of aqueous dispersions of lipid-based lyotropic liquid crystalline phases, namely reversed types of hexagonal and bicontinious cubic phases. As stabilizer a nonionic triblock polymer proves to be efficient for dispersions of both phases. We demonstrate that these dispersions contain submicron particles with a preserved inner periodicity. The morphology and inner structure of the dispersed particles are characterized by means of SAXS (small-angle X-ray scattering) and cryo-TEM (cryo-transmission electron microscopy). The particle shape is shown to reflect the crystallinity of the lipid structure. Thus the morphology of particles from cubic phases differs from that of the ones obtained from the hexagonal phase. Furthermore, an interesting difference is found in the partitioning of the polymer in the two types of dispersions. The polymer is localized within the core as well as at the surface of the dispersed particles of the cubic phase, whereas the core.
A Direct Synthesis of Mesoporous Carbons with Bicontinuous Pore Morphology from Crude Plant Material by Hydrothermal Carbonization

Hydrothermal carbonization is a convenient way to convert biomass at rather moderate conditions into carbonaceous nanostructures, here, mesoporous network structures. A structural view on the micro- and nanoscale reveals interesting features defining the usefulness and application possibilities of the resulting carbonaceous materials as supports and for sorption purposes. Whereas weakly connected plant tissues result in good yields of carbon nanoparticles with very small sizes where the porosity is mainly interstitial, “hard” plant tissue is structurally transformed into a carbon replica with a rather well-defined, bicontinuous mesopore structure.
Improved k-Anonymize and l-Diverse Approach for Privacy Preserving Big Data Publishing Using MPSEC Dataset

Data exposure and privacy violations may happen when data is exchanged between organizations. Data anonymization gives promising results for limiting such dangers. In order to maintain privacy, diﬀerent methods of k -ano- nymization and l -diversity have been widely used. But for larger datasets, the results are not very promising. The main problem with existing anonymization algorithms is high information loss and high running time. To overcome this problem, this paper proposes new models, namely Improved k -Anonymization (IKA) and Improved l -Diversity (ILD). IKA model takes large k -value using a symmetric as well as an asymmetric anonymizing algorithm. Then IKA is further categorized into Improved Symmetric k -Anonymization (ISKA) and Improved Asymmetric k - Anonymization (IAKA). After anonymizing data using IKA, ILD model is used to increase privacy. ILD will make the data more diverse and thereby increasing privacy. This paper presents the implementation of the proposed IKA and ILD model using real-time big candidate election dataset, which is acquired from the Madhya Pradesh State Election Commission, India (MPSEC) along with Apache Storm. This paper also compares the proposed model with existing algorithms, i.e. Fast clustering-based Anonymization for Data Streams (FADS), Fast Anonymiza-tion for Data Stream (FAST), Map Reduce Anonymization (MRA) and Scalable k -Anonymization (SKA). The experimental results show that the proposed models IKA and ILD have remarkable improvement of information loss and signiﬁcantly enhanced the performance in terms of running time over the existing approaches along with maintaining the privacy-utility trade-oﬀ
Thin film properties and surface morphology of metal free phthalocyanine films grown by organic molecular beam deposition

The structure, optical properties and surface morphology of thin films of metal free phthalocyanine (H2Pc) deposited in an ultra-high vacuum environment by organic molecular beam deposition have been studied using a variety of ex-situ techniques. The growth conditions have a strong influence on the properties of the films. H2Pc undergoes a phase transition (α→β) at a deposition temperature of ∽330°C, or upon post annealing a film grown at room temperature. Both the structure and optical properties of the films change and powder X-ray diffraction, electronic absorption spectroscopy, Raman and photoluminescence spectroscopies are used to characterise the differences between the two phases. Atomic force microscopy and Nomarski interference microscopy show that the lower temperature α-phase is characterised by a smooth morphology with spherical islands that show no apparent long-range order. By contrast, the β-phase has a much greater root mean square roughness and long thin needle-like crystals are observed on the surface of the films. The morphology of the β-phase depends on the method of preparation and there are two distinct types, β1 and β2. The crystallites show a preferential orientation and alignment with respect to each other for growth at room temperature followed by annealing (β1), but are randomly oriented for films grown at elevated substrate temperatures (β2).
Antioxidant, Antiproliferative Activities and Chemical Profile of Clinacanthus nutans Leaf Extracts Processed Using Two Different Pre-Extraction Drying Methods

Introduction: Clinacanthus nutans (CN) is a medicinal herb that is traditionally used in Southeast Asia as a treatment for disease and prevention of cancer. Objective: The goal of this study was to investigate the effects of different drying processes on properties of CN. Methods: Air dried (ADDCM) and oven dried (ODDCM) leaves were extracted using the dichloromethane (DCM) Soxhlet extraction method. Antioxidant activity of the extracts was measured using the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) scavenging assay. The chemical profile of the extracts was determined using gas chromatography-mass spectrometry (GC-MS) analysis, and the antiproliferative activity was tested using MCF-7 (breast cancer) and MCF- 10A (normal breast) cell lines and the Sulphoromide B assay. Results: The percentage of scavenging ability was 12.354 ± 0.003% and 13.151 ± 0.009% for ADDCM and ODDCM, respectively, with r2 values of 0.969 and 0.968. The total content of DPPH scavenging radicals in the ADDCM and ODDCM extracts significantly correlated with their trolox relaxation effects (r2 >0.9, p<0.05). GC-MS identified 89 major phytochemical compounds present in both extracts. The antiproliferative effects of both extracts on MCF-7 cells were dose dependent. No antiproliferative effect was detected for MCF-10A cells. Conclusion: Both extracts exhibited free radical scavenging activity, but the ADDCM extract contained a greater amount of chemical compounds. Additionally, the DCM extracts showed selective antiproliferative activity against MCF-7 but not MCF-10A.
Adversarial Unsupervised Domain Adaptation for Harmonic-Percussive Source Separation

This letter addresses the problem of domain adaptation for the task of music source separation. Using datasets from two different domains, we compare the performance of a deep learning-based harmonic-percussive source separation model under different training scenarios, including supervised joint training using data from both domains and pre-training in one domain with fine-tuning in another. We propose an adversarial unsupervised domain adaptation approach suitable for the case where no labelled data (ground-truth source signals) from a target domain is available. By leveraging unlabelled data (only mixtures) from this domain, experiments show that our framework can improve separation performance on the new domain without losing any considerable performance on the original domain. The letter also introduces the Tap & Fiddle dataset, a dataset containing recordings of Scandinavian fiddle tunes along with isolated tracks for “foot-tapping” and “violin”.
A New Class of Wideband MS-to-MS Vialess Vertical Transition With Function of Filtering Performance

A new class of wideband microstrip (MS)-to-microstrip (MS) vialess vertical transition with function of filtering performance is proposed and demonstrated on coplanar waveguide (CPW) resonator in this brief. Initially, a higher unloaded quality factor (<inline-formula> <tex-math notation="LaTeX">${Q} _{u}$ </tex-math></inline-formula>) in the proposed CPW resonator than a conventional slotline resonator shows that the CPW resonator is a better choice for design of the proposed transition than its counterpart on slotline resonator. Meanwhile, to give an insight into the <inline-formula> <tex-math notation="LaTeX">${Q} _{u}$ </tex-math></inline-formula> of the CPW resonator, the underlying working mechanism how the proposed CPW resonator is provided with higher <inline-formula> <tex-math notation="LaTeX">${Q} _{u}$ </tex-math></inline-formula> than the slotline resonator is elaborated. Then, resonant mode in the proposed CPW resonator will be properly investigated. After that, to facilitate design process, a synthesis design method is introduced for design of the proposed transition. Finally, one design example, i.e., a three-pole vertical transition, is designed, constructed, and experimentally verified. The three sets of results, i.e., expected, simulated and measured results of the proposed transition match well with each other.
Theoretical Study of the Postgel Regime in Thermoreversible Gelation

Phase diagrams of thermoreversible gels are derived by the use of two different conventional postgel treatments, i.e., Flory's treatment and Stockmayer's treatment. Phase diagrams by Flory's treatment, which allows cycle formation in the gel network, often show two critical points for intermediate association constants, one in the sol region and the other in the gel region. In such a case three-phase equilibrium temperature appears. Existence of a critical solution point in the gel region suggests the possibility of phase separation into a dilute gel and a concentrated gel. One of these two critical points is a conventional type that lies on the stable coexistence curve (binodal), but the other one may lie on the metastable binodal. In contrast, phase diagrams by Stockmayer's treatment, which strictly excludes cycle formation in the gel network, often lead to the appearance of a tricritical point (TCP) where sol/gel transition curve intersects with the binodal line. This treatment gives no critical soluti.
