A capillary dielectrophoretic chip for real-time blood cell separation from a drop of whole blood (2013)

This study proposes a capillary dielectrophoretic chip to separate blood cells from a drop of whole blood (approximately 1 μl) sample using negative dielectrophoretic force. The separating efficiency was evaluated by analyzing the image before and after dielectrophoretic force manipulation. Blood samples with various hematocrits (10%-60%) were tested with varied separating voltages and chip designs. In this study, a chip with 50 μm gap design achieved a separation efficiency of approximately 90% within 30 s when the hematocrit was in the range of 10%-50%. Furthermore, glucose concentration was electrochemically measured by separating electrodes following manipulation. The current response increased significantly (8.8-fold) after blood cell separation, which was attributed not only to the blood cell separation but also to sample disturbance by the dielectrophoretic force.
A Coreflood Simulation Study of a Systematic Co2 Huff-N-Puff Injection for Storage and Enhanced Gas Condensate Recovery (2022)

Abstract Recently some core flood experimental data were reported following a new CO2 Huff-n-Puff (H-n-P) injection technique. This technique optimized CO2 injection pressure and volume to improve CO2/resident fluid interactions for enhanced gas and condensate recovery and CO2 storage purposes. This simulation study aims to complement and generalize the corresponding core flood experimental results. The simulation data confirm the dominant governing mechanism and the importance of using appropriate CO2/gas-condensate kr data while accounting for the effect of compositional changes on gas and condensate mobility during CO2 H-n-P injection. Laboratory PVT tests were performed to generate relevant data sets that describe the complex phase behavior changes when CO2 interacts with gas condensate systems. These data sets were applied for EOS tuning, phase behavior prediction, and quantifying the level of CO2/gas condensate interactions. A CO2 H-n-P injection core-flood simulation model was developed. H-n-P injection cycles with the incremental injection of CO2 volumes were simulated to replicate experimental procedures performed on a high-permeability Berea sandstone core. Experimental data showed that conventional CO2 H-n-P injection treatment significantly improves hydrocarbon gas and condensate recovery efficiency but at the cost of injecting and producing high volumes of CO2. While the proposed method applied at the maximum condensate saturation for the corresponding CO2/gas-condensate mixture can match the recovery efficiency achieved when applying the conventional injection technique, but with much lesser volumes of CO2 injected and produced. The relative permeability data measured for gas and condensate fluids (GC-kr) were significantly affected by the compositional changes resulting from CO2/resident fluid interactions below the saturation pressure. The numerical model predicted a close match for the pressure profile after adjusting the GC-kr data. However, it could only match the production profile for the pre-CO2 and first CO2 injection cycle, where the volume of CO2 injected was small and had a negligible effect on condensate recovered relative to the volume of condensate in place. Sensitivity analyses were performed on GC-kr data attempting to history match the experimental and simulated data. The generated data were analyzed to quantify the effects of CO2/resident fluid interactions on condensate revaporization and the model's predictability. These data will aid in bridging the gap in the level of CO2/gas-condensate interactions during CO2 flooding, which is vital for designing an efficient CO2 H-n-P injection process.

Optimization of the IV Measurement of Advanced Structures (2010)

The classification of solar cells and the comparison of cells from different origins is typically based on the cell efficiencies. As a consequence, the efficiency and the related parameters of short circuit current, open-circuit voltage and fill factor need to be measured precisely. This requires an IV setup with a small bias error and a good stability over time. In this study, an IV setup is gradually improved by the stepwise implementation of several adaptations. The effect of these improvements on the measured solar cell parameters is tracked and after completion of the improvement process, the measured parameters are compared to the values measured at a calibration lab to quantify the bias error of the final setup.
Testability strategy for registers and memories in a multi-processor architecture (2003)

A testability strategy is presented for registers and memories embedded in multiprocessor chips designed with the Cathedral-II silicon compilation environment. The implementation requires the design of a scan register that is able to maintain a value at its output while scanning a vector into the scan chain. A test algorithm for the register file, based on the concept of C-testability, is derived. The fault model covers both stuck-at and most of the transistor stuck-open and stuck-close cases. In addition, large embedded memories are important in processor systems. A test strategy with very high fault coverage is implemented with a self-test approach.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Orthogonalization Using Multicarrier Pre-Decorrelation in a Multipath Fading Channel (Special Section on Spread Spectrum Techniques and Applications) (1997)

<b>Background:</b> Appendicitis is a common condition affecting 7-8% of the general population. With the improvement of noninvasive imaging, the diagnostic approach and treatment algorithm for patients with clear signs and symptoms suggestive of acute appendicitis are well agreed-upon. However, patients without pathognomonic signs and symptoms, but with equivocal imaging pose a diagnostic dilemma. These patients may still have acute appendicitis and could potentially benefit from laparoscopic appendectomy. This may be especially true in the subset of patients with appendicoliths.<b>Methods:</b> Our case series exams a group of patients with atypical symptoms who eventually underwent appendectomy and were followed after surgery for at least a month. This case series consists of eight patients with abdominal pain accompanied by a variety of other signs and symptoms in addition to laboratory results and imagining characteristics which were nondiagnostic. These patients had initial Alvarado scores ranging from 0-6.<b>Results:</b> All of these patients were subsequently taken to the operating room for diagnostic laparoscopy and laparoscopic appendectomy. Of these patients, six were known to have appendicoliths based on computed tomography obtained during initial diagnostic workup.<b>Conclusions:</b> All patients underwent a diagnostic laparoscopy and appendectomy. Four had appendicitis and four also had resolution of their symptoms. There exist atypical presentations of appendiceal disease. Patients with abdominal pain/tenderness, even without diagnostic laboratory results or imaging characteristics, may benefit from laparoscopic appendectomy.
A hybrid data-driven solution to facilitate safe mud window prediction (2022)

Safe mud window (SMW) defines the allowable limits of the mud weights that can be used while drilling O&G wells. Controlling the mud weight within the SMW limits would help avoid many serious problems such as wellbore instability issues, loss of circulation, etc. SMW can be defined by the minimum mud weight below which shear failure (breakout) may occur (MW<sub>BO</sub>) and the maximum mud weight above which tensile failure (breakdown) may occur (MW<sub>BD</sub>). These limits can be determined from the geomechanical analysis of downhole formations. However, such analysis is not always accessible for most drilled wells. Therefore, in this study, a new approach is introduced to develop a new data-driven model to estimate the safe mud weight range in no time and without additional cost. New models were developed using an artificial neural network (ANN) to estimate both MW<sub>BO</sub> and MW<sub>BD</sub> directly from the logging data that are usually available for most wells. The ANN-based models were trained using actual data from a Middle Eastern field before being tested by an unseen dataset. The models achieved high accuracy exceeding 92% upon comparing the predicted and observed output values. Additionally, new equations were established based on the optimized ANN models' weights and biases whereby both MW<sub>BO</sub> and MW<sub>BD</sub> can be calculated without the need for any complicated codes. Finally, another dataset from the same field was then used to validate the new equations and the results demonstrated the high robustness of the new equations to estimate MW<sub>BO</sub> and MW<sub>BD</sub> with a low mean absolute percentage error of 0.60% at maximum. So, unlike the costly conventional approaches, the newly developed equations would facilitate determining the SMW limits in a timely and economically effective way, with high accuracy whenever the logging data are available.

Urea-Functionalized M4L6 Cage Receptors: Anion-Templated Self-Assembly and Selective Guest Exchange in Aqueous Solutions (2012)

We present an extensive study of a novel class of de novo designed tetrahedral M(4)L(6) (M = Ni, Zn) cage receptors, wherein internal decoration of the cage cavities with urea anion-binding groups, via functionalization of the organic components L, led to selective encapsulation of tetrahedral oxoanions EO(4)(n-) (E = S, Se, Cr, Mo, W, n = 2; E = P, n = 3) from aqueous solutions, based on shape, size, and charge recognition. External functionalization with tBu groups led to enhanced solubility of the cages in aqueous methanol solutions, thereby allowing for their thorough characterization by multinuclear ((1)H, (13)C, (77)Se) and diffusion NMR spectroscopies. Additional experimental characterization by electrospray ionization mass spectrometry, UV-vis spectroscopy, and single-crystal X-ray diffraction, as well as theoretical calculations, led to a detailed understanding of the cage structures, self-assembly, and anion encapsulation. We found that the cage self-assembly is templated by EO(4)(n-) oxoanions (n ≥ 2), and upon removal of the templating anion the tetrahedral M(4)L(6) cages rearrange into different coordination assemblies. The exchange selectivity among EO(4)(n-) oxoanions has been investigated with (77)Se NMR spectroscopy using (77)SeO(4)(2-) as an anionic probe, which found the following selectivity trend: PO(4)(3-) ≫ CrO(4)(2-) > SO(4)(2-) > SeO(4)(2-) > MoO(4)(2-) > WO(4)(2-). In addition to the complementarity and flexibility of the cage receptor, a combination of factors have been found to contribute to the observed anion selectivity, including the anions' charge, size, hydration, basicity, and hydrogen-bond acceptor abilities.
Indoor Wireless Channel Properties at Millimeter Wave and Sub-Terahertz Frequencies (2019)

This paper provides indoor reflection, scattering, transmission, and large-scale path loss measurements and models, which describe the main propagation mechanisms at millimeter wave and Terahertz frequencies. Channel properties for common building materials (drywall and clear glass) are carefully studied at 28, 73, and 140 GHz using a wideband sliding correlation based channel sounder system with rotatable narrow-beam horn antennas. Reflection coefficient is shown to linearly increase as the incident angle increases, and lower reflection loss (e.g., stronger reflections) are observed as frequencies increase for a given incident angle. Although backscatter from drywall is present at 28, 73, and 140 GHz, smooth surfaces (like drywall) are shown to be modeled as a simple reflected surface, since the scattered power is 20 dB or more below the reflected power over the measured range of frequency and angles. Partition loss tends to increase with frequency, but the amount of loss is material dependent. Both clear glass and drywall are shown to induce a depolarizing effect, which becomes more prominent as frequency increases. Indoor propagation measurements and large-scale indoor path loss models at 140 GHz are provided, revealing similar path loss exponent and shadow fading as observed at 28 and 73 GHz. The measurements and models in this paper can be used for future wireless system design and other applications within buildings for frequencies above 100 GHz.
Erythropoietin in cardioprotection: does it have a future or is it all in the past? (2008)

Over the past two decades, we have seen a gradual reduction in mortality from myocardial infarction due in a large part to the advent of revascularization and other cardioprotective strategies. However, myocardial infarction is still the most common cause of morbidity, related primarily to the loss of left ventricular function and mortality. A host of novel strategies are being examined to limit myocardial infarct size. Towards that goal, several investigators have suggested that erythropoietin (EPO) therapy may hold a new promise. The article by Kobayashi et al. in the current issue of Cardiovascular Research describes a new drug delivery protocol for the use of EPO in the post-myocardial infarction setting.1

### 2.1 Preclinical studies

It is well known that EPO stimulates the plasma haemoglobin concentration in patients with cancers or renal disease. Receptors for EPO have been shown to be present on vascular smooth muscle cells, endothelial cells, and cardiomyocytes,2 and EPO appears to exert its effect on myocardial function by stimulating EPO receptors on cardiomyocytes.

Previous studies have shown that EPO administration reduces the myocardial infarct size after ischaemia.3,4 Gao et al. 5 showed that treatment with a long-acting EPO preparation as late as 24 h after the onset of the ischaemic process provided a significant reduction in myocardial …

Fluorescence characteristics of dissolved organic matter from dumped waste leachate. (2010)

In order to reveal the characteristics of composition of leachates from dumped waste and their variations,three-dimensional excitation-emission matrix fluorescence spectroscopy(3DEEM) were applied for dissolved organic matter(DOM) of leachates extracted from four different dumped waste.Leachate sample S1 contained two different kinds of protein-like fluorescence peak,i.e.,tyrosine-like and tryptophan-like fluorescence peaks.The other three samples(S2,S3 and S4),however,in addition to tryptophan-like fluorescence,contained humus-like fluorescence peaks as well,and the number,type and location of the peaks were different in according to samples.Leachate samples S1 contained only protein-like matter,while the other three samples contained both humus-like matter and protein-like matter,and the degree of humification of humus-like matter varied in different samples.The complexation between the protein-like matter in sample S1 and Hg(II) indicated that,compared with tryptophan-like fluorescence peak,tyrosine-like fluorescence peak could be more easily impacted by the micro-environmental change;the results of culture experiments at room temperature demonstrated that,protein-like substance could be easily broken,while humus-like substance shown strong resistance to microbe.3DEEM could be effectively characterized the composition of DOM of leachates from dumped waste and their variations.
The Consequences of Stigma for Knowledge Production: Sheep Producers' Attitudes to Footrot Diagnostics and Control in Australia (2020)

In Australia, there is documented confusion from producers around the clinical disease of footrot, and anecdotally, knowledge of what tools are available for the diagnosis and management of footrot. When discussing footrot with producers, the authors noted a hesitation to discuss, with denial often expressed. The disease can be debilitating, both on the sheep's welfare and the producer's well-being, as it is a very difficult disease to manage and eradicate. Gaining an understanding of producer perceptions of the disease may help ensure any future actions for management and control are in-line with those identified by producers. A combination of a web-based, and manually distributed surveys of 45 sheep producers was conducted. This included closed- and open-ended questions, multi check box, and Likert scales. Responses were quantified by descriptive statistics and a thematic analysis conducted of short answers. The results of this survey indicate satisfaction with footrot diagnostics is low, while satisfaction with control methods is high. There was also a poor general understanding of footrot as a disease, and a general distrust in peers when it comes to correct management of footrot. This research addresses a gap in the literature about how sociological conditions affect diagnosis and control of footrot disease. It provides three main recommendations-simplifying the diagnostic message, encouraging a culture of trust among sheep producers and increasing governmental support-as a way to tackle this problem.

Hemoperfusion and Immunomodulation (2023)

Recent development in sorbent technology has spurred new interest in the potential of hemoperfusion (HP) in clinical conditions such as cytokine release syndromes and sepsis. Although the role of nonselective HP in such conditions requires solid evidence and more studies, the rationale for clinical application is clearly emerging. Greater biocompatibility and safety of the new sorbents may allow easy and safe application of HP in those conditions where the innate and the adaptive immune response of the individual appears to be dysregulated. Recent results in small studies seem to confirm the plausibility for this therapeutic approach. The concept suggested by the peak concentration hypothesis justifies new studies and the application of HP in selected patients to remove the peaks of circulating mediators responsible for conditions of hyperinflammation or immunodepression.
Skewing Adjacent Line Repeaters to Reduce the Delay and Energy Dissipation of On-Chip Buses (2005)

The paper proposes a bus architecture which improves the performance and/or power dissipation of online buses. The proposed architecture reduces the delay on alternate lines by lowering its repeaters' threshold voltages, V/sub t/. Furthermore, the shifting of the signal switching on adjacent lines reduces the worst-case coupling capacitance. Two implementations of this bus architecture are proposed, the alternate-V/sub t/ (AVT) and the alternate forward body bias (ABB) schemes, and are compared to a conventional bus (CB) scheme. For a flop distance of 1800 /spl mu/m, the proposed schemes use the gained delay slack to reduce the total device width, thus reducing the energy dissipation by 31.2%. For a 500 ps cycle time, the proposed bus schemes increase the maximum distance between flip-flops by 33%.
Abstract P025: Modulatory Effect of Angiotensin II on Endothelial Differentiation and Vasculogenic Capacity of Human MSCs (2011)

Human bone marrow-derived mesenchymal stem cell (MSC)-based therapy holds great promise as a new approach for cardiovascular regeneration. In heart failure, there is activation of the renin-angiotensin system and increased formation of angiotensin (Ang) II. We tested the hypothesis that Ang II impairs endothelial differentiation and vasculogenic capacity of human MSCs. MSCs were cultured in endothelial growth media (EGM) and treated with vehicle, 1µM Ang II, or 10µM Ang II for 7 days to assess by real time RT-PCR the expression of two markers of endothelial differentiation, platelet endothelial cell adhesion molecule (PECAM) and von Willebrand factor (vWF). Expression of PECAM and vWF increased similarly in each treatment group at day 7, suggesting endothelial differentiation of MSCs. To assess vasculogenesis, MSCs were cultured in EGM for 7 days and then plated on growth factor reduced Matrigel for 5 hours under the following conditions: vehicle, Ang II (1µM), Ang II + type 1 receptor (AT1R) inhibitor (10µM losartan), or Ang II + type 2 receptor (AT2R) inhibitor (0.1µM PD123177). The vascular index (VI) was determined by multiplying the average number of endothelial tubes formed by the average tube length. MSCs treated for 5 hours with 1µM Ang II exhibited a reduced VI (84.5 ± 2.6% of vehicle treated cells, P&lt;0.05). Treatment with Ang II+AT1R inhibitor increased VI (115 ± 4.9% of vehicle, P&lt;0.05) whereas Ang II+AT2R inhibitor decreased VI (77.1 ± 4.1% of vehicle, P&lt;0.05). Chronic treatment for 7 days in EGM with 1µM or 10µM Ang II also showed decreased VI compared to vehicle (75.4 ± 5.4% and 60.7 ± 2% of vehicle, respectively, P&lt;0.01). These results reveal that both acute and chronic treatment with Ang II produces a negative effect on the vasculogenic potential of endothelial-differentiated human MSCs and suggests opposing effects of AT1R and AT2R on vasculogenesis. In conclusion, we propose that selective modulation of AT1R and AT2R mediated pathways may serve as a promising means for enhancing the regenerative capacity of human MSCs in cardiovascular disease.
Energy-conserving go-back-N ARQ protocols for wireless data networks (2002)

Mobile computer communications fundamentally implies reliance on a self-contained, portable power source and communications over an error-prone fading radio channel. We propose two energy-conserving alternatives to the classical go-back-N ARQ protocol which allow a substantial energy saving over the traditional approach by reducing the number of uplink acknowledgments required, while preserving good delay/throughput performance.
