A Bad Data Identification Method for Multiple Spatio-temporal Data in Power Distribution Network (2018)

Due to the excessive number of databases, unbalanced development and behindhand sensing infrastructures, distributed network data suffers from inconsistency, data missing, large measurement error and other data quality problems, which hinder the development of smart distribution network. In order to discover more complex deep-seated rules and provide more effective decision support for power system decision-making, it is necessary to study data mining and analysis methods that are suitable for massive data under current situation. This paper studies on the method of identifying bad data for multi-temporal and multi-spatial data in distribution networks and propose a method to identify bad data using likelihood-ratio test for 3D spatio-temporal data. In order to speed up the data processing rate, a 3D-LRT method based on multi-threading and Hadoop parallelization methods is proposed.
Anchoring of Drifting Spiral and Scroll Waves to Impermeable Inclusions in Excitable Media (2012)

Anchoring of spiral and scroll waves in excitable media has attracted considerable interest in the context of cardiac arrhythmias. Here, by bombarding inclusions with drifting spiral and scroll waves, we explore the forces exerted by inclusions onto an approaching spiral and derive the equations of motion governing spiral dynamics in the vicinity of inclusion. We demonstrate that these forces nonmonotonically depend on distance and can lead to complex behavior: (a) anchoring to small but circumnavigating larger inclusions; (b) chirality-dependent anchoring.
Flooding characteristics of packed columns with high efficiency. [SDC protruded distillation, Podbielniak bronze Helipak, Norton pall ring, Goodloe mesh] (1976)

Flooding characteristics of four high efficiency column packings, including Scientific Development Co. (SDC) protruded stainless distillation packing, Norton stainless pall rings, Podbielniak bronze Helipak, and Goodloe stainless wire mesh packing were determined experimentally. Two Plexiglas columns (6.35 cm ID and 15.2 cm ID) filled with these packings were operated with countercurrent air and water streams. Pressure drop data were recorded for different liquid and gas flow rates, packings, and column sizes to determine the flooding velocity. The protruded distillation, Helipak, and pall ring packing results, in dimensionless coordinates, were within 35 percent below and 25 percent above the values expected from the Eckert correlation on the smallest diameter column. The distillation packing fell short of the manufacturer's predicted flooding velocity by an order of magnitude, while the Goodloe mesh showed experimental capacity results less than 45 percent below those expected by the manufacturer. 12 fig.

GP73 promotes invasion and metastasis of bladder cancer by regulating the epithelial–mesenchymal transition through the TGF‐β1/Smad2 signalling pathway (2018)

This study investigated the effects of Golgi membrane protein 73 (GP73) on the epithelial-mesenchymal transition (EMT) and on bladder cancer cell invasion and metastasis through the TGF-β1/Smad2 signalling pathway. Paired bladder cancer and adjacent tissue samples (102) and normal bladder tissue samples (106) were obtained. Bladder cancer cell lines (T24, 5637, RT4, 253J and J82) were selected and assigned to blank, negative control (NC), TGF-β, thrombospondin-1 (TSP-1), TGF-β1+ TSP-1, GP73-siRNA-1, GP73-siRNA-2, GP73-siRNA-1+ TSP-1, GP73-siRNA-1+ pcDNA-GP73, WT1-siRNA and WT1-siRNA + GP73-siRNA-1 groups. Expressions of GP73, TGF-β1, Smad2, p-Smad2, E-cadherin and vimentin were detected using RT-qPCR and Western blotting. Cell proliferation, migration and invasion were determined using MTT assay, scratch testing and Transwell assay, respectively. Compared with the blank and NC groups, levels of GP73, TGF-β1, Smad2, p-Smad2, N-cadherin and vimentin decreased, and levels of WT1 and E-cadherin increased in the GP73-siRNA-1 and GP73-siRNA-2 groups, while the opposite results were observed in the WT1 siRNA, TGF-β, TSP-1 and TGF-β + TSP-1 groups. Cell proliferation, migration and invasion notably decreased in the GP73-siRNA-1 and GP73-siRNA-2 groups in comparison with the blank and NC groups, while in the WT1 siRNA, TGF-β, TSP-1 and TGF-β + TSP-1 groups, cell migration, invasion and proliferation showed the reduction after the EMT. These results suggest that GP73 promotes bladder cancer invasion and metastasis by inducing the EMT through down-regulating WT1 levels and activating the TGF-β1/Smad2 signalling pathway.
Characterisation and Corrosion-Erosion Behaviour of Carbide based Thermal Spray Coatings (2012)

Thermal spraying has emerged as a suitable and effective surface engineering technology and is widely used to apply wear, erosion and corrosion protective coatings for various kinds of industrial applications. Cr 3 C 2 -based coatings have been applied to a wide range of industrial components. Cr 3 C 2 -NiCr coatings offer greater corrosion and oxidation resistance, also having a high melting point and maintaining high hardness, strength and wear resistance up to a maximum operating temperature of 900 C. The corrosion resistance is provided by NiCr matrix while the wear resistance is mainly due to the carbide ceramic phase. This paper reviews the performance, developments and applications of Cr 3 C 2 -NiCr thermal spray coatings for corrosion/erosion-corrosion under different types of environments and outlines the characterization of Cr 3 C 2 -NiCr coatings with respect to their microstructure and mechanical properties, together with some brief characterisation work by the author for HVOF sprayed 75Cr 3 C 2 -25NiCr coating on T91 boiler steel.
Cryogenic sapphire oscillator with improved frequency stability (2002)

Extremely high short-term frequency stability has been realized in oscillators based on liquid helium cooled sapphire resonators with a modified mounting structure. These oscillators have exhibited an Allan deviation of about 5.4/spl times/10/sup -16/spl tau/1/2/ for integration time /spl tau/ of 1-4 s and a minimum Allan frequency deviation of 2.4/spl times/10/sup -16/ at 32 s.
A Theoretical Design of a Flattening Filter to Improve Field Uniformity of a Superficial Therapeutic X-Ray Beam (2001)

A Monte Carlo model has been developed using the EGS4 code to aid the design of a flattening filter, to improve field uni- formity of a superficial X-ray machine. The machine is operating at 90 kV and filtered with a 1.1 mm aluminium filter. In the theoretical simulation the original flat filter was replaced by a varying thickness filter to improve the uniformity across field sizes 20, 5 and 2 cm diameter as well as hardening the beam. Simulation results showed that flatness of the beam profile was improved for the 20 cm field size from ±7.3% to ±1.1% across the anode/cathode direction, and from ±7.7% to ±3.2% in the anode/cathode direction. For the 5 cm field size the improvement was from ±4.6% to ±3.1% and from ±5.5% to ±3.4%, and for the 2 cm field size from ±3.1% to ±2.4% and from ±10.2% to ±9.5%, in the same directions, respectively. Beam quality simulations were made and the original half-value layer was reduced from 2.21 ± 0.09 mm aluminium to 2.04 ± 0.09 mm aluminium. The study demonstrated that it was possible to build a filter capable of flat- tening the beam profile for different sized applicators without sig- nificantly changing the penetrating ability of the beam.
Compact Phase-Reconfigurable Couplers With Wide Tuning Range (2019)

To meet the stringent requirements of the emerging wireless communication system, the components should exhibit high flexibility in the control of operating frequency, amplitude characteristics, and also phase characteristics. Among them, the reconfigurability in phase is important but difficult to implement. The existing phase-reconfigurable coupler can only provide a tuning range between 45° and 135°, resulting in limited applications. To solve this problem, a tunable unit consisting of open and shorted stubs and tunable capacitors is introduced between two eighth wavelength coupled lines to construct a compact phase-tunable coupler. For the first time, the continuous tuning range of a phase-reconfigurable coupler is extended to 0°-180°. The corresponding theoretical analysis has been conducted. For the demonstration, two couplers operating at 2.4 GHz were fabricated and measured. Good agreement between simulation and measurement can be observed. Coupler I achieved a phase tuning range from 45° to 135°, maintaining equal power division characteristics. The amplitude bandwidth defined by 10-dB return loss and 1-dB amplitude imbalance was larger than 16.3% for all states. Coupler II provided a tunable phase from 0° to 180° over an amplitude bandwidth larger than 12.5%. These results validate the effectiveness of the proposed structures.
Investigation of an amoxicillin oxidative degradation product formed under controlled environmental conditions (2010)

Environmental context.Although amoxicillin is a widely used antibiotic, it is yet to be detected in the aquatic environment. This study traces the production of the amoxicillin-S-oxide degradation product, and shows that it is consistently obtained only under sunlight irradiation. This is the first study to demonstrate the formation, under controlled environmental conditions, of this chemically stable product of amoxicillin. Abstract.Amoxicillin (AMX) is a widely used penicillin-type antibiotic, and its presence in the environment has been widely investigated. The formation and structure of an oxidised degradation product (DP) of AMX are described in the present work. The experiments were carried out in buffer solution (pH 7.5) containing AMX at a concentration of 100 μg mL–1, with and without acid and in field secondary effluent. The DP, AMX-S-oxide (sulfoxide), was consistently obtained only under sunlight irradiation and was significantly augmented by the addition of humic acid (5 mg L–1) and mainly in field secondary effluent, which acts as a natural photo-sensitiser. The structure of the AMX-S-oxide DP was determined by an LC-MS technique using a mobile phase of deuterated and non-deuterated solvents. A 1H NMR spectrum was obtained for the pure compound isolated by preparative HPLC. Further confirmation of the AMX-S-oxide structure was achieved by comparison of its UV spectrum with those of the two oxidation products, AMX-S-oxide and hydroxylated AMX, obtained by the ozonolysis of AMX.
Altered Retinoid Uptake and Action Contributes to Cell Survival in Endometriosis (2010)

In endometrial stromal cells, progesterone receptor up-regulates expression of STRA6 and CRABP2, which control retinol uptake and growth-suppressor actions of RA. In endometriotic stromal cells, decreased expression of these genes leads to decreased retinol uptake and dominant FABP5-mediated prosurvival activity.
Complete amino acid sequence of the thioesterase domain of chicken liver fatty acid synthase (1988)

The complete amino acid sequence of thioesterase domain of chicken liver fatty acid synthase has been determined by sequencing peptides produced by trypsin, Staphylococcus aureus V8 protease, and cyanogen bromide cleavage. The thioesterase domain consists of 300 amino acid residues. All of the tryptic peptides of the thioesterase domain were isolated and sequenced, except the segment covered from position 109 to position 124. Peptides resulting from digestion by Staphylococcus aureus V8 protease and cyanogen bromide cleavage filled the missing part and overlapped the complete sequence of the entire thioesterase domain. The NH2 terminus of the thioesterase domain was determined to be lysine by sequencing the whole domain up to 20 residues while the COOH terminus was identified as serine through carboxyl peptidase Y cleavage. The active site of the thioesterase domain of chicken fatty acid synthase was suggested to be the serine on position 101 according to its homology with other serine-type esterases and proteases which have a common structure of -Gly-X-Ser-Y-Gly- with the variable amino acids X and Y disrupting the homology.

Ensemble data assimilation applied to an adaptive mesh ocean model (2016)

Summary In this study, a first attempt has been made to introduce mesh adaptivity into the ensemble Kalman fiter (EnKF) method. The EnKF data assimilation system was established for an unstructured adaptive mesh ocean model (Fluidity, Imperial College London). The mesh adaptivity involved using high resolution mesh at the regions of large flow gradients and around the observation points in order to reduce the representativeness errors of the observations. The use of adaptive meshes unavoidably introduces difficulties in the implementation of EnKF. The ensembles are defined at different meshes. To overcome the difficulties, a supermesh technique is employed for generating a reference mesh. The ensembles are then interpolated from their own mesh onto the reference mesh. The performance of the new EnKF data assimilation system has been tested in the Munk gyre flow test case. The discussion of this paper will focus on (a) the development of the EnKF data assimilation system within an adaptive mesh model and (b) the advantages of mesh adaptivity in the ocean data assimilation model.

Federated Semisupervised Learning for Attack Detection in Industrial Internet of Things (2022)

Security has become a critical issue for Industry4.0 due to different emerging cyber-security threats. Recently, many deep learning (DL) approaches have focused on intrusion detection. However, such approaches often require sending data to a central entity. This in turn raises concerns related to privacy, efficiency, and latency. Despite the huge amount of data generated by the Internet of Things (IoT) devices in Industry 4.0, it is difficult to get labeled data, because data labeling is costly and time-consuming. This poses many challenges for several DL approaches, which require labeled data. In order to deal with these issues, new approaches should be adopted. This article proposes a novel federated semisupervised learning scheme that takes advantage of both unlabeled and labeled data in a federated way. First, an autoencoder (AE) is trained on each device (using unlabeled local/private data) to learn the representative and low-dimensional features. Then, a cloud server aggregates these models into a global AE using federated learning (FL). Finally, the cloud server composes a supervised neural network, by adding fully connected layers (FCN) to the global encoder (the first part of the global AE) and trains the resulting model using publicly available labeled data. Extensive case studies on two real-world industrial datasets demonstrate that our model: (a) ensures that no local private data is exchanged; (b) detects attacks with high classification performance, (c) works even when only a few amounts of labeled data are available; and (d) haslow communication overhead.
A grid-connected hybrid cascaded H-bridge inverter (2011)

To satisfy the need of high performance, a grid-connected hybrid cascaded H-bridge single-phase inverter is proposed. The topology of the inverter has different DC voltages, and a modulation method minimizing the switching loss is applied. In order to improve the control performance, the phase lock loop (PLL) based on generalized second-order integrator is adopted. A current controller based on Proportional-Resonant (PR) regulator is also employed. The feasibility and effectiveness of the cascaded grid-connected inverter system are verified by simulations and experiments.
A local human Vδ1 T cell population is associated with survival in nonsmall-cell lung cancer (2022)

Murine tissues harbor signature γδ T cell compartments with profound yet differential impacts on carcinogenesis. Conversely, human tissue-resident γδ cells are less well defined. In the present study, we show that human lung tissues harbor a resident Vδ1 γδ T cell population. Moreover, we demonstrate that Vδ1 T cells with resident memory and effector memory phenotypes were enriched in lung tumors compared with nontumor lung tissues. Intratumoral Vδ1 T cells possessed stem-like features and were skewed toward cytolysis and helper T cell type 1 function, akin to intratumoral natural killer and CD8<sup>+</sup> T cells considered beneficial to the patient. Indeed, ongoing remission post-surgery was significantly associated with the numbers of CD45RA<sup>-</sup>CD27<sup>-</sup> effector memory Vδ1 T cells in tumors and, most strikingly, with the numbers of CD103<sup>+</sup> tissue-resident Vδ1 T cells in nonmalignant lung tissues. Our findings offer basic insights into human body surface immunology that collectively support integrating Vδ1 T cell biology into immunotherapeutic strategies for nonsmall cell lung cancer.
Natriuretic Response to Saline Load in One-Kidney/One-Clip Hypertensive Rats (1990)

Parameters of renal function were studied in conscious and anesthetized one-kidney (1K) and one-kidney/one-clip (1K-1C) rats. Effective renal blood flow (ERBF) was significantly lower in anesthetized 1K-1C rats than in conscious ones (12.1 +/- 1.6 vs. 16.4 +/- 1.2 ml/min). Renal function was evaluated in two-kidney (2K), 1K and 1K-1C unanesthetized rats. ERBF was lower in 1K and 1K-1C animals than in 2K rats. Glomerular filtration rate (GFR) and urinary sodium excretion (UNa.V) were not affected by uninephrectomy with or without clipping the renal artery. In 1K-1C rats, mean arterial pressure (MAP) increased from 100 +/- 2 to 140 +/- 1 mm Hg. Subsequently, the renal ability of unanesthetized rats to handle Na was studied by a sustained extracellular fluid volume expansion (EFVE) in all groups. During EFVE, MAP remained unchanged in the 2K and 1K groups and decreased significantly in the 1K-1C group, ERBF did not change and GFR increased to the same extent in all groups. The increase in UNa.V was 40% higher in 2K than in 1K or 1K-1C rats. These findings indicate that the relatively smaller natriuretic response to a saline load of 1K rats with or without a clip in the renal artery, as compared with 2K rats, could be ascribed to renal mass reduction. Finally, the study shows the advantage of performing studies of renal function in hypertension in conscious rather than anesthetized rats.
GSQR: A generic service quality reporting protocol for terminals (2011)

The most accurate way of evaluating the customer experience of a service is to monitor the service at the point where the service is delivered; that is at the terminal on which the service is running. There has been some research work and standardization efforts on QoS and QoE reporting on terminals and as yet no unified approach for terminal reporting has been described. This paper describes such a generic mechanism for ordering, collecting, and enhancing terminal reports.
