Systems Design and Economic Analysis of Direct Air Capture of CO<sub>2</sub> through Temperature Vacuum Swing Adsorption Using MIL-101(Cr)-PEI-800 and mmen-Mg<sub>2</sub>(dobpdc) MOF Adsorbents (2016)

Direct air capture (DAC) removes CO2 from the atmosphere and can therefore address sizable nonpoint sources emissions of CO2 such as those from transportation. We propose a five-step temperature vacuum swing adsorption process for direct air capture using solid adsorbents coated as films on monolithic contactors using steam as the stripping agent during desorption. We perform a modeling study and economic assessment for DAC using two metal organic frameworks, MIL-101(Cr)-PEI-800 and mmen-Mg2(dobpdc), for which we have experimentally demonstrated film growth on monolith structures. The results indicate minimum energy requirements, and cost estimates are 0.145 MJ/mol-CO2 and $75–140/t-CO2 for MIL-101(Cr)-PEI-800, and 0.113 MJ/mol-CO2 and $60–190/t-CO2 for mmen-Mg2(dobpdc), respectively. The overall DAC cost is sensitive to adsorbent purchase cost and lifetime as well as cycle parameters such as adsorption and desorption times. We conclude that mmen-Mg2(dobpdc) has better performance compared to MIL-101(Cr)-PEI-800 in terms of energy requirements because of its higher capacity and nonlinear isotherm.
Sol–gel coatings for corrosion protection of metals (2005)

Sol–gel derived films exhibit a high potential as substitutes for the environmentally unfriendly chromate metal-surface pre-treatment methods. Inorganic sol–gel derived films offer good adhesion between metals and organic paint. However, they cannot provide adequate corrosion protection due to their high crack-forming potential. Introduction of an organic component to an inorganic sol–gel system leads to the formation of thicker, more flexible and functionalized films with enhanced compatibility to different organic top coatings. Incorporation of nanoparticles in the hybrid sol–gel systems increases the corrosion protection properties due to lower porosity and lower cracking potential along with enhancement of the mechanical properties. Furthermore, the incorporation of inorganic nanoparticles can be a way to insert corrosion inhibitors, preparing inhibitor nanoreservoirs for “self-repairing” pre-treatments with controlled release properties.

Disorders of the inhibitory glycine receptor: the <i>spastic</i> mouse (1990)

The mutant mouse spastic suffers from a motor disorder of autosomal recessive inheritance which is characterized by tremor, myoclonic episodes, and a disturbed righting response. The most prominent alteration in the mutant is a substantial deficit of postsynaptic glycine receptor channels resulting in a dramatic reduction of glycinergic synaptic inhibition. Function and structure of the glycine receptor protein appear unaffected, which argues for a regulatory rather than a structural effect of the spastic mutation. It appears that other alterations in the spastic mouse are secondary to this fundamental disturbance in the balance of excitatory and inhibitory impulses. In particular, a significant increase in GABAA receptors of the lower parts of the CNS may serve a compensatory function, counteracting in part losses of glycinergic inhibition. Pharmacological experiments indeed show that facilitation of GABAA receptor-mediated inhibition alleviates symptoms of the spastic motor disorder. The recent cDNA cloning of glycine receptor subunits should help define the molecular mechanism by which the spastic gene causes the glycine receptor deficit.
Isolation and sequencing of a genomic clone encoding aspartic proteinase of Rhizopus niveus (1988)

A gene encoding Rhizopus niveus aspartic proteinase was isolated from an R. niveus genomic library by using oligonucleotides probes corresponding to its partial amino acid sequence, and its nucleotide sequence was determined. By comparing its deduced amino acid sequence with the amino acid sequence of rhizopuspepsin (5, 26), we concluded that the R. niveus aspartic proteinase gene has an intron within its coding region and that it has a preproenzyme sequence of 66 amino acids upstream of the mature enzyme of 323 amino acids.

A Practical Review of C-Peptide Testing in Diabetes (2017)

C-peptide is a widely used measure of pancreatic beta cell function. It is produced in equimolar amounts to endogenous insulin but is excreted at a more constant rate over a longer time. Methods of estimation include urinary and unstimulated and stimulated serum sampling. Modern assays detect levels of c-peptide which can be used to guide diabetes diagnosis and management. We explore the evidence behind the various tests available. We recommend the glucagon stimulation c-peptide testing owing to its balance of sensitivity and practicality. C-peptide levels are associated with diabetes type and duration of disease. Specifically a c-peptide level of less than 0.2 nmol/l is associated with a diagnosis of type 1 diabetes mellitus (T1DM). C-peptide level may correlate with microvascular and macrovascular complications and future use of insulin therapy, as well as likely response to other individual therapies. We explore the potential uses of c-peptide measurement in clinical practice.
Charged Particles Modulate Local Ionic Concentrations and Cause Formation of Positive Peaks in Resistive-Pulse-Based Detection (2014)

We study the effect of electrolyte concentration on the shape of ion current pulses in resistive-pulse sensing. We show that electrokinetic passage of several hundred nanometers in diameter charged polystyrene particles through a micropore leads to formation of current increase when the particles exit the pore. The particle entrance, as reported before, causes formation of the current decrease, which is a measure of the particle size. Formation of the double peak, i.e., current decrease followed by a current increase, is especially pronounced if the resistive-pulse experiments are carried out in KCl concentrations below 200 mM. In order to explain the pulse shape, experiments were designed in which the particles passed through the pore only by either electroosmosis or electrophoresis. The presented experiments and modeling indicate that while both electroosmosis and electrophoresis affect the ion current pulse, formation of the positive peak is mainly determined by the latter effect and the charged state of the particle. The importance of the findings for resistive-pulse analysis is discussed.
Integrated Crash Avoidance and Mitigation Algorithm for Autonomous Vehicles (2021)

This article presents a novel integrated path-following, crash avoidance, and crash mitigation control algorithm for autonomous vehicles. To improve stability and tracking accuracy of the algorithm in extreme conditions, combined-slip tire forces are considered in the system model. A predictive control framework that monitors slip conditions at each tire is then developed to achieve good dynamics performance by controlling active front steer and brake modulation at each corner. A novel switching mechanism that does not rely on a separate path generation module is designed for avoidance and mitigation phases, which is verified in various harsh driving conditions. Another strong point is the objective function for the crash mitigation phase that is developed based on real-world crash statistics. Simulation results confirm that the proposed algorithm can not only track the desired path in normal driving phase, but also avoid crash and reduce crash severity with ensured vehicle stability.
On a class of optimal nonbinary linear unequal-error-protection codes for two sets of messages (1994)

Several authors have addressed the problem of designing good linear unequal error protection (LUEP) codes. However, very little is known about good nonbinary LUEP codes. The authors present a class of optimal nonbinary LUEP codes for two different sets of messages. By combining t-error-correcting Reed-Solomon (RS) codes and shortened nonbinary Hamming codes, they obtain nonbinary LUEP codes that protect one set of messages against any t or fewer symbol errors and the remaining set of messages against any single symbol error. For t/spl ges/2, they show that these codes are optimal in the sense of achieving the Hamming lower bound on the number of redundant symbols of a nonbinary LUEP code with the same parameters.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
An Accurate Lifetime Analysis Methodology Incorporating Governing NBTI Mechanisms in High-k/SiO2 Gate Stacks (2006)

Extraction of the intrinsic NBTI degradation rate in the high-k pMOSFETs was found to require correction of the measured threshold voltage shift (DeltaV <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TH</sub> ) for the fast transient charging contribution caused by the charge trapping in pre-existing defects in high-k films. The proposed analysis methodology leads to a significantly lower estimated lifetime than that obtained by the generally used approach. It was determined that the interface state generation process contains a fast component most likely associated with the defects in the SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> interfacial layer induced by the overlaying high-k film.

A shallow water inline multiplexed sensor system used for inwater tracking (1994)

The portable tracking system (PTS) will design, activate and validate a portable underwater/in-air instrumented range capability which can be deployed in most water depths and any ocean locations, This capability will be provided through two suites of inwater hardware. The deep PTS system is a transponder based system that provides up to 500 square nautical miles (915 square kilometers) for a test area with depths ranging from 1000 to 20000 feet (approximately 305 to 6096 meters). The shallow PTS system is an inline multiplexed system on a fiber optic cable supporting up to 100 square nautical miles (approximately 183 square kilometers) with depths ranging from 200 to 2000 feet (approximately 61 to 610 meters). The shallow water in-line multiplexed sensor system (SWIMSS) is a prototype PTS shallow water system. It consists of ten in-line hydrophone sensor nodes. Each sensor node is connected via one nautical mile (approximately 1.83 kilometers) of electrical mechanical optical cable(EMOC). The SWIMSS is deployed from the stem of a ship with the use of a linear cable engine. The hydrophone sensors are broadband and are used to telemeter inwater acoustic ping signals back to a signal processor and automatic data processing equipment suite where pings are detected and inwater vehicles are tracked and displayed.
Glioblastoma Cells Require Glutamate Dehydrogenase to Survive Impairments of Glucose Metabolism or Akt Signaling (2009)

Oncogenes influence nutrient metabolism and nutrient dependence. The oncogene c-Myc stimulates glutamine metabolism and renders cells dependent on glutamine to sustain viability ("glutamine addiction"), suggesting that treatments targeting glutamine metabolism might selectively kill c-Myc-transformed tumor cells. However, many current or proposed cancer therapies interfere with the metabolism of glucose, not glutamine. Here, we studied how c-Myc-transformed cells maintained viability when glucose metabolism was impaired. In SF188 glioblastoma cells, glucose deprivation did not affect net glutamine utilization but elicited a switch in the pathways used to deliver glutamine carbon to the tricarboxylic acid cycle, with a large increase in the activity of glutamate dehydrogenase (GDH). The effect on GDH resulted from the loss of glycolysis because it could be mimicked with the glycolytic inhibitor 2-deoxyglucose and reversed with a pyruvate analogue. Furthermore, inhibition of Akt signaling, which facilitates glycolysis, increased GDH activity whereas overexpression of Akt suppressed it, suggesting that Akt indirectly regulates GDH through its effects on glucose metabolism. Suppression of GDH activity with RNA interference or an inhibitor showed that the enzyme is dispensable in cells able to metabolize glucose but is required for cells to survive impairments of glycolysis brought about by glucose deprivation, 2-deoxyglucose, or Akt inhibition. Thus, inhibition of GDH converted these glutamine-addicted cells to glucose-addicted cells. The findings emphasize the integration of glucose metabolism, glutamine metabolism, and oncogenic signaling in glioblastoma cells and suggest that exploiting compensatory pathways of glutamine metabolism can improve the efficacy of cancer treatments that impair glucose utilization.
Muscular Factors are of Importance in Tension‐Type Headache (1998)

Recent studies have indicated that muscular disorders may be of importance for the development of increased pain sensitivity in patients with chronic tension-type headache. The objective of the present study was to investigate this hypothesis by examining the pain perception in tension-type headache with and without muscular disorders defined as increased tenderness. We examined 28 patients with episodic tension-type headache, 28 patients with chronic tension-type headache, and 30 healthy controls. Pericranial myofascial tenderness was recorded with manual palpation, and pressure pain detection and tolerances in cephalic and extracephalic locations with an electronic pressure algometer. In addition, thermal pain sensitivity and electromyographic activity were recorded. The main result was significantly lower pressure pain detection thresholds and tolerances in all the examined locations in patients with chronic tension-type headache with a muscular disorder compared to those without a muscular disorder. There were no such differences in any of the examined locations when the two subgroups of patients with episodic tension-type headache were compared. Thermal pain sensitivity did not differ between patients with and without a muscular disorder, while electromyographic activity levels were significantly higher in patients with chronic tension-type headache with than in those without a muscular disorder. Our results strongly indicate that prolonged nociceptive stimuli from the pericranial myofascial tissue sensitize the central nervous system and, thereby, lead to an increased general pain sensitivity. Muscular factors may, therefore, be of major importance for the conversion of episodic into chronic tension-type headache. The present study complements the understanding of the important interactions between peripheral and central factors in tension-type headache and may lead to a better prevention and treatment of the most prevalent type of headache.

Low‐voltage bulk‐driven input stage with improved transconductance (2010)

Abstract A low‐voltage input stage constructed from bulk‐driven PMOS transistors is proposed in this paper. It is based on a partial positive feedback and offers significant improvement of both input transconductance and noise performance compared with those achieved by the corresponding already published bulk‐driven structures. The proposed input stage offers also extended input common‐mode range under low supply voltage in relevant to a gate‐driven differential pair. A differential amplifier based on the proposed input stage is also designed, which includes an auxiliary amplifier for the output common‐mode voltage stabilization and a latch‐up protection circuitry. Both input stage and amplifier circuits were implemented with 1 V supply voltage using standard 0.35µm CMOS process, and their performance evaluation gave very promising results.

Faster elliptic curve point multiplication based on a novel greedy base-2,3 method (2006)

In this paper a novel pre-computation technique for scalar point multiplication on elliptic curves is proposed. Compared to standard affine coordinates without pre-computation this method achieves a performance increase of 23% while requiring an additional increase in control and logic for the pre-computation step. This method achieves a (2m bits times numpoints) reduction in storage overhead compared with other pre-computation techniques
Unsupervised Extraction of Flood-Induced Backscatter Changes in SAR Data Using Markov Image Modeling on Irregular Graphs (2010)

The near real-time provision of precise information about flood dynamics from synthetic aperture radar (SAR) data is an essential task in disaster management. A novel tile-based parametric thresholding approach under the generalized Gaussian assumption is applied on normalized change index data to automatically solve the three-class change detection problem in large-size images with small class a priori probabilities. The thresholding result is used for the initialization of a hybrid Markov model which integrates scale-dependent and spatiocontextual information into the labeling process by combining hierarchical with noncausal Markov image modeling. Hierarchical maximum a posteriori (HMAP) estimation using the Markov chains in scale, originally developed on quadtrees, is adapted to hierarchical irregular graphs. To reduce the computational effort of the iterative optimization process that is related to noncausal Markov models, a Markov random field (MRF) approach is defined, which is applied on a restricted region of the lowest level of the graph, selected according to the HMAP labeling result. The experiments that were performed on a bitemporal TerraSAR-X StripMap data set from South West England during and after a large-scale flooding in 2007 confirm the effectiveness of the proposed change detection method and show an increased classification accuracy of the hybrid MRF model in comparison to the sole application of the HMAP estimation. Additionally, the impact of the graph structure and the chosen model parameters on the labeling result as well as on the performance is discussed.

Perchlorate as a secondary substrate in a denitrifying, hollow-fiber membrane biofilm reactor (2002)

In recent years, several oxyanions have emerged as drinking water micropollutants, including arsenate, selenate, bromate, and, most recently, perchlorate (ClO4-). Conventional water treatment processes typically are ineffective in removing these compounds, and advanced treatment processes are expensive. Biological reduction may provide a suitable treatment alternative, since these compounds can serve as electron acceptors. Other acceptors, such as nitrate (NO3-), must act as a primary electron acceptor. We tested our denitrifying, autotrophic, hydrogen-oxidizing hollow-fiber membrane for ClO4- reduction. The reactor is highly suited to drinking water treatment, as hydrogen (H2) is inexpensive, non-toxic, and does not leave residuals that can cause regrowth. When 1 to 2 mg/L ClO4- was supplied to reactor, which was at steady-state with 5 mgN/L NO3- but unacclimated to ClO4-, ClO4- removals increased from 40 to 99% over three weeks. Removals to 4 μg/L were also achieved in a natural groundwater having 6 to 100 μg/L ClO4-. Tests with variable NO3- and H2 showed that ClO4- reduction requires less than 30 μgN/L NO3- and at least 300-μg/L effluent H2. Therefore, partial denitrification is probably not consistent with excellent ClO4- removal. Mineral medium produced a gradual loss of ClO4--reducing bacteria, but they were re-enriched when tap water replaced minimal medium.
