Low Power Consumption Nanofilamentary ECM and VCM Cells in a Single Sidewall of High‐Density VRRAM Arrays (2019)

The technologies of 3D vertical architecture have made a major breakthrough in establishing high-density memory structures. Combined with an array structure, a 3D high-density vertical resistive random access memory (VRRAM) cross-point array is demonstrated to efficiently increase the device density. Though electrochemical migration (ECM) resistive random access (RRAM) has the advantage of low power consumption, the stability of the operating voltage requires further improvements due to filament expansions and deterioration. In this work, 3D-VRRAM arrays are designed. Two-layered RRAM cells, with one inert and one active sidewall electrode stacked at a cross-point, are constructed, where the thin film sidewall electrode in the VRRAM structure is beneficial for confining the expansions of the conducting filaments. Thus, the top cell (Pt/ZnO/Pt) and the bottom cell (Ag/ZnO/Pt) in the VRRAM structure, which are switched by different mechanisms, can be analyzed at the same time. The oxygen vacancy filaments in the Pt/ZnO/Pt cell and Ag filaments in the Ag/ZnO/Pt cell are verified. The 40 nm thickness sidewall electrode restricts the filament size to nanoscale, which demonstrates the stability of the operating voltages. Additionally, the 0.3 V operating voltage of Ag/ZnO/Pt ECM VRRAM demonstrates the potential of low power consumption of VRRAM arrays in future applications.
Merging infrared and color visible images with an contrast enhanced fusion method (2007)

We propose a contrast enhanced fusion (CEF) method for merging infrared and color visible images. The CEF method
can be carried out in two ways: the standard CEF method and the fast CEF method. The standard method transforms the
original RGB color visible image into a linear luminance-chrominance color space in order to treat the achromatic and
chromatic components separately. The achromatic component and infrared image are combined by a grayscale fusion
scheme, and the original achromatic component is replaced by the grayscale fused image. Before the data are
retransformed back into the RGB color space, the means and variances between the original achromatic component and
the grayscale fused image are matched by a linear luminance remapping. The remapping procedure can fairly enhance
the contrast of the final color fused image. The standard CEF method can be implemented efficiently by the fast CEF
method that has the same fusion performance as the standard approach but manipulates images directly in RGB color
space. We used the proposed method to merge long wave infrared and color TV images. The experimental results show
that the CEF method can effectively produce a high-contrast color fused image with similar natural color characteristics
as the original color visible image. In addition, we have also illustrated that the hybrid simple and complex CEF methods
can be applied as a region of interest (ROI) image fusion solution, which allows ROIs to be fused with better quality
than the rest of the original images.
XAFS Spectroscopy Analysis of Selected Elements in Fine Particulate Matter Derived from Coal Combustion (2002)

X-ray absorption fine structure (XAFS) spectroscopy has been used to investigate the valence states and molecular structures of sulfur (S), chromium (Cr), arsenic (As), and zinc (Zn) in fine particulate matter (PM) separated from coal fly ash produced in a laboratory combustion system. A cyclone separator was used to separate the PM into fractions <2.5 μm in mean diameter (PM2.5) and >2.5 μm in diameter (PM2.5+). Sulfate was the dominant form of S present. However, thiophene was present in many samples, and sulfite was significant in two of the PM2.5+ samples. For Cr and As, the valence states were of primary concern. Analysis of the X-ray absorption near-edge structure (XANES) regions of the spectra revealed that the toxic Cr6+ valence state accounted for approximately 10 to 30% of the Cr in PM derived from the fly ash of several coals from the western United States. However, only Cr3+ was observed in a number of PM samples from eastern U.S. bituminous coal fly ash. For As, only As5+ as arsenate was detected in all samples examined. However, subtle spectral differences were observed between the arsenate forms observed in western and eastern coal fly ash PM. Zn exhibited a rich chemistry, with significant variation in the major phases observed for eastern coal fly ash PM (principally ZnFe2O4) and western coal fly ash PM (mixed phases). These phase differences undoubtedly reflect the differences in the suites of inorganic constituents contained in the parent coals.
Dynamic management for business processes modeling & execution in workflows (2001)

Contemporary workflow-management systems cannot represent change or evolution of business processes. When a change is needed due to external reason, an offline procedure is invoked in order to create a new workflow engine template for the future instances in the workflow enactment module. The standard interfaces do not deal with the business process metadata in a way that can actually change it as a reaction to inbound knowledge. There are many relevant cases, especially in the virtual enterprise arena, where the business process is not deterministic and is influenced by external parameters (such as the selection of virtual partners), so the knowledge of what should be done is available, however it is external to the system. There is a need to develop a modeling mechanism that enables to transfer process definitions in an automatic way, without the need for human interference. One way of confronting with these issues is the use of a rule-based engine to monitor business process execution. This engine will contain internal meta-rules that refer to metadata entities, i.e. rules that describe how to act on other rules (business process routing) when a change is detected, while executing all needed consistency checks.
Structural Health Monitoring in Civil Aviation: Applications and Integration (2013)

&lt;div class="section abstract"&gt;&lt;div class="htmlview paragraph"&gt;In civil aviation the main driver for Structural Health Monitoring (SHM) is to provide maintenance and ownership benefits. The maintenance benefits are defined in terms of improving maintenance planning, increasing inspection intervals and reducing inspection cost. The ownership benefits can be measured in residual value and life extension.&lt;/div&gt;&lt;div class="htmlview paragraph"&gt;In this paper different aspects of SHM implementation are discussed for fatigue monitoring and fatigue damage sensing with a consideration of minimizing challenges for SHM implementation. First, the current Fatigue Monitoring implementation scenarios for the most representative agile military aircraft are reviewed. In the following some aircraft utilization results obtained from analyzing different airlines are presented. The obtained results show a better possibility of categorizing fleet of an airline in comparison with agile military aircraft. Based on these results a concept for fatigue monitoring of a civil aircraft is proposed that can be implemented with a minimum certification challenges. Cumulative damage calculated based on the proposed concept shows potential opportunity for more granulated life evaluation, which can result in up to 25% fatigue maintenance interval extension by adding take-off weight part of the fatigue parameters. Second, a typical recognized application for fatigue damage sensing using Acousto-Ultrasonics technology is presented and a typical inspection result that can be expected from the SHM system is discussed. In addition, some specific experimental observations for sensors' performance are presented that need to be taken into account at low Technology Readiness Levels (TRLs) where the SHM solution performance is evaluated.&lt;/div&gt;&lt;/div&gt;

Robust 17 W single-pass second-harmonic-generation at 532 nm and relative-intensity-noise investigation (2020)

We demonstrate a 17 W single-frequency, low-intensity-noise green source at 532 nm, by single-pass second-harmonic generation of a 50 W continuous-wave fiber laser in a 30 mm MgO-doped periodically-poled stoichiometric lithium tantalate crystal. The maximum conversion efficiency is about 37%. A nearly Gaussian beam (<i>M</i><sup>2</sup><1.15 at 15 W) and low wavefront distortion are obtained. The system shows stable behavior over 100 h of uninterrupted operation. The evolution of the relative-intensity-noise transfer from the fundamental to the second harmonic is theoretically and experimentally investigated with high resolution.
Emergence of carbapenem-non-susceptible extended-spectrum β-lactamase-producing Klebsiella pneumoniae isolates at the university hospital of Tübingen, Germany (2009)

The spread of Gram-negative bacteria with plasmid-borne extended-spectrum beta-lactamases (ESBLs) has become a worldwide problem. This study analysed a total of 366 ESBL-producing Enterobacteriaceae strains isolated from non-selected patient specimens at the university hospital of Tübingen in the period January 2003 to December 2007. Although the overall ESBL rate was comparatively low (1.6 %), the percentages of ESBL-producing Enterobacter spp. and Escherichia coli increased from 0.8 and 0.5 %, respectively, in 2003 to 4.6 and 3.8 % in 2007. In particular, the emergence was observed of one carbapenem-resistant ESBL-producing E. coli isolate and five carbapenem-non-susceptible ESBL-positive Klebsiella pneumoniae isolates, in two of which carbapenem resistance development was documented in vivo under a meropenem-containing antibiotic regime. The possible underlying mechanism for this carbapenem resistance in three of the K. pneumoniae isolates was loss of the Klebsiella porin channel protein OmpK36 as shown by PCR analysis. The remaining two K. pneumoniae isolates exhibited increased expression of a tripartite AcrAB-TolC efflux pump as demonstrated by SDS-PAGE and mass spectrometry analysis of bacterial outer-membrane extracts, which, in addition to other unknown mechanisms, may contribute towards increasing the carbapenem MIC values further. Carbapenem-non-susceptible ESBL isolates may pose a new problem in the future due to possible outbreak situations and limited antibiotic treatment options. Therefore, a systematic exploration of intestinal colonization with ESBL isolates should be reconsidered, at least for haemato-oncological departments from where four of the five carbapenem-non-susceptible ESBL isolates originated.

Identification of Defense-Related Rice Genes by Suppression Subtractive Hybridization and Differential Screening (2001)

Identification of host genes involved in defense responses is one of most critical steps leading to the elucidation of disease resistance mechanisms in plants. In this study, two different cloning strategies were employed to identify defense-related genes from a tropical japonica rice cultivar (Oryza sativa cv. Drew). With the use of bacterial colony arrays, differential screening of a blast fungus (Pyricularia grisea)-induced rice cDNA library led to the isolation of 22 distinct rice genes that are expressed differentially in response to blast infection. Sequence analysis indicates that most of them are full-length cDNAs encoding pathogenesis-related proteins or other relatively abundant proteins. In combination with treatments of cycloheximide plus jasmonic acid (JA) or benzothiadiazole (BTH) in rice seedlings, the polymerase chain reaction-based suppression subtractive hybridization also was conducted to search for immediate early (IE) defense-related genes whose transcription is independent of de novo protein synthesis. The initial screening of only 768 subtracted clones resulted in the identification of 34 distinct IE genes that are induced by JA, BTH, and/or blast infection. Database searches revealed that these IE genes encode putative mitogen-activated protein kinase, diacylglycerol kinase, zinc finger protein, RelA-SpoT protein, ankyrin-containing protein, ABC transporter, beta-ketoacyl-CoA synthase, and other potential defense-signaling components. Further characterization of these novel IE genes will likely facilitate the elucidation of defense signal transduction in rice plants.
Extended spectrum β-lactamase-producing Escherichia coli forms filaments as an initial response to cefotaxime treatment (2015)

We showed that E. coli resistant to β-lactams by an extended-spectrum β-lactamase, bla CTX-M-1, produced filaments when exposed to cefotaxime. The filament formation was restricted to early growth phases and the time the cells grew as filaments was antibiotic concentration dependent. This indicates that antibiotic resistant E. coli undergo the same morphological changes as sensitive bacteria in the presence of β-lactam antibiotic. It was showed that the filament formation was an initial response to the antibiotics.
Protein kinase C‐β, fibronectin, α5β1‐integrin, and tumor necrosis factor‐α are required for phorbol diester–induced apoptosis in human myeloid leukemia cells (2001)

The human myeloid HL-60 cell line and its cell variant HL-525 were used to study signaling events leading to apoptosis induction by phorbol 12-myristate 13-acetate (PMA), an activator of protein kinase C (PKC) enzymes. Unlike parental cells, HL-525 cells are PKC-beta deficient and resistant to PMA-induced apoptosis. These cells regain susceptibility to apoptosis induction after transfection with a PKC-beta expression vector. By using this vector and specific neutralizing monoclonal antibodies (mAbs), it was established that PMA-induced apoptosis also called for an interaction between cell-surface alpha(5)beta(1)-integrin and its deposited ligand fibronectin (FN), which is downstream of PKC-beta activation. Experiments with mAbs, the PKC-beta vector, and exogenous FN revealed that the next step entailed an interaction between secreted tumor necrosis factor-alpha and its type I receptor. By using a sphingomyelinase inhibitor, it was concluded that the subsequent step involved ceramide production. Moreover, a permeable ceramide was effective in inducing apoptosis in both HL-60 and HL-525 cells, and this induction was caspase-1 and/or -4 dependent because an inhibitor of these caspases abrogated the induced apoptosis. Based on these and related differentiation studies, we conclude that the above signaling events, the early ones in particular, are shared with PMA-induced macrophage differentiation in the HL-60 cells. It is likely that once these cells acquire their macrophage phenotype and perform their tasks, they become superfluous and are eliminated from the body by a self-triggered apoptotic process that involves our proposed signaling scheme.

Prompting people with dementia to carry out tasks: What works and why? (2012)

This two-year project aims to investigate in detail how prompting can help to guide people with dementia through tasks independently in a domestic setting. Four formats of prompt (text, audio, video and picture) are being compared with each other during domestic user-testing visits, to establish the relative strengths and weaknesses of each format. The importance of providing overall task context at each step, and ways of manual or automatic forwarding to the next instruction, will also be explored. Early findings from user testing have shown that comparable text or audio prompts are more effective means of prompting than picture or video prompts, and that there is strong potential for people with dementia to be able to control the timing of the prompts to work through the task at their own pace. These findings will be combined and the prompts will be developed iteratively so that prototype pieces of prompting technology can be created to enable a person with dementia to successfully carry out a task independently.
Defect Creation in HKUST‐1 via Molecular Imprinting: Attaining Anionic Framework Property and Mesoporosity for Cation Exchange Applications (2017)

Abstract Discovering new methods to tailor the physical and chemical properties of metal–organic frameworks (MOFs) for their numerous potential applications is highly desired. In this work, engineering defects in MOF via a molecular imprinting approach is developed to endow HKUST‐1, a well‐studied classical MOF, with hierarchical structure, mesoporosity, and anionic framework property. Ringlike anionic HKUST‐1 (HKUST‐1‐R) and a wide variety of metal‐doped isostructural analogues ( M /HKUST‐1‐R, M = Ca, Cd, Ce, Co, Li, Mn, Na, Ni, or Zn) are obtained. The benefits of transforming imprinted HKUST‐1‐R to M /HKUST‐1‐R are further demonstrated for various applications. This synthetic strategy is therefore suitable for rational design and functionalization of MOFs in addition to their morphological control in nanoscale.
Radiographic Hip Joint Phenotype of the Pembroke Welsh Corgi (2012)

Corgis had a low frequency of conventional OA despite having hip laxity that has been shown to correlate with hip OA and hip dysplasia in large-breed dogs. The relationship between CCO and OA was similar to published findings in nonchondrodystrophic large-breed dogs and the CFHO was significantly associated with subluxation. Both CCO and CFHO are associated with hip dysplasia in this small chondrodystrophic breed.
Efficient Organic Semiconductors Containing Fluorine-Substituted Benzothiadiazole for Solution-Processed Small Molecule Organic Solar Cells (2012)

The synthesis and photovoltaic characteristics of new organic semiconductors, [bisDMFA-Th]-BT-HxTh3 (1), [bisDMFA-Th]-MonoF-BT-HxTh3 (2), and [bisDMFA-Th]-DiF-BT-HxTh3 (3), are reported. These semiconductors have an unsymmetrical donor A–acceptor–donor B (DA-A-DB) framework composed of a benzothiadiazole (BT; fluorinated or unfluorinated) acceptor between two different donors, bisDMFA and terthiophene. We have demonstrated that these compounds are suitable for use in p-type organic semiconductors for high efficiency solution-processed small molecule organic solar cells (SMOSCs), for which we achieved a remarkable power conversion efficiency of 4.24% with a maximum Voc of 0.89 V. The fluorine substitution on BT decreased its HOMO level and increased hole mobilities of [bisDMFA-Th]-BT-HxTh3 derivatives, leading to an increased Voc in the SMOSCs and improved hole carrier transport properties of the material. In addition, we determined that the insertion of a TiOx functional layer into a bulk heterojunction (BHJ) solar cell significantly reduced the interfacial resistance between the photoactive film and metal electrode, resulting in an increased photocurrent with facile electron transfer between these two layers.
Towards Sustainable Digital Twins for Vertical Farming (2018)

We present a model to implement digital twins in sustainable agriculture. Our two-year research project follows the design science research paradigm, aiming at the joint creation of physical and digital layers of IoT-enabled structures for vertical farming. The proposed model deploys IoT to (1) improve productivity, (2) allow self-configuration to environmental changes, (3) promote energy saving, (4) ensure self-protection with continuous structural monitoring, and (5) reach self-optimization learning from multiple data sources. Our model shows how digital twins can contribute to the agrofood lifecycle of planning, operation, monitoring, and optimization. Moreover, it clarifies the interconnections between goals, tasks, and resources of IoT-enabled structures for sustainable agriculture, which is one of the biggest human challenges of this century.

Alkali therapy for prevention of acute kidney injury in rhabdomyolysis (2022)

Rhabdomyolysis is a syndrome characterized by breakdown of skeletal muscle and leakage of cellular constituents, including electrolytes, myoglobin, and other cytoplasmic proteins, into circulation In the United States, the National Hospital Discharge Survey has reported 26,000 cases of rhabdomyolysis annually The etiology of rhabdomyolysis is diverse and includes trauma, therapeutic agents, substance abuse, infection, hyperthermia, toxins, genetic defects, and metabolic diseases Acute kidney injury (AKI) reportedly occurs in 14% to 46% of patients with rhabdomyolysis, and about 28% to 37% of adults with AKI require temporary hemodialysis Therefore, AKI is a serious complication of rhabdomyolysis, regardless of the cause. Early recognition and prevention of AKI are the most important steps in treatment of rhabdomyolysis. Myoglobin is known to be the main cause of AKI in rhabdomyolysis cases. The myoglobin leaked from damaged skeletal muscle accumulates in serum and is observed in urine as a reddish-brown substance when the serum myoglobin concentration exceeds 100 mg/dL Acidic urine and increased uric acid in the urine can precipitate inter-
