Surface temperature estimation of li-ion battery via thermal impulse response technique (2015)

This paper focuses on the prediction of temperature profiles on the surface of Lithium-ion cells. In particular, the paper proposes the adoption of the impulse response technique to predict cell surface temperatures consequent to generic discharge conditions applied to the targeted cell. The method is fed by data obtained by dedicated experiments to be performed on the targeted cell. In order to feed the proposed method, these experiments aim at obtaining cell surface temperature profiles consequent to short-time current discharge impulses. A set of dedicated validations is finally included in the paper in order to verify the validity of the proposed method.
A Noninvasive Method for Monitoring Renal Status at Bedside (1997)

T1 of an appendage remote from the kidneys reflects the concentration of gadolinium in the blood, which is in rapid equilibrium with tissue interstitial space gadolinium. The decay in T1 of the appendage reflects glomerular filtration. Thus, it is feasible to detect changes in renal status at a patient's bedside by monitoring T1 of a finger or wrist using a small, inexpensive magnet.
Intelligent Omni-Surface: Ubiquitous Wireless Transmission by Reflective-Transmissive Metasurface (2020)

Intelligent reflecting surface (IRS), which is capable to adjust propagation conditions by controlling phase shifts of the reflected waves that impinge on the surface, has been widely analyzed for enhancing the performance of wireless systems. However, the reflective properties of widely studied IRSs restrict the service coverage to only one side of the surface. In this paper, to extend the wireless coverage of communication systems, we introduce the concept of intelligent omni-surface (IOS)-assisted communication. More precisely, IOS is an important instance of reconfigurable intelligent surface (RIS) that is capable to provide service coverage to the mobile users (MUs) in a reflective and a transmissive manner. We consider a downlink IOS-assisted communication system, where a multi-antenna small base station (SBS) and an IOS perform beamforming jointly, to improve the received power of multiple MUs on both sides of the IOS, through different reflective/transmissive channels. To maximize the sum-rate, we formulate a joint IOS phase shift design and SBS beamforming optimization problem, and propose an iterative algorithm to solve the resulting non-convex program efficiently. Both theoretical analysis and simulation results show that an IOS significantly extends the service coverage of the SBS when compared to an IRS.
Fractals in the nervous system: conceptual implications for theoretical neuroscience (2010)

This essay is presented with two principal objectives in mind: first, to document the prevalence of fractals at all levels of the nervous system, giving credence to the notion of their functional relevance; and second, to draw attention to the as yet still unresolved issues of the detailed relationships among power-law scaling, self-similarity, and self-organized criticality. As regards criticality, I will document that it has become a pivotal reference point in Neurodynamics. Furthermore, I will emphasize the not yet fully appreciated significance of allometric control processes. For dynamic fractals, I will assemble reasons for attributing to them the capacity to adapt task execution to contextual changes across a range of scales. The final Section consists of general reflections on the implications of the reviewed data, and identifies what appear to be issues of fundamental importance for future research in the rapidly evolving topic of this review.

In demo case, it proves this method can mitigate the unknown PIM signal at most of 20dB at LTE band of 2600MHz.
Abstract 5615: Dual Role of the Small G Protein Rac-1 in the Regulation of Hypoxia-Induced STAT3 Activation in Endothelial Cells (2009)

The Signal Transducer and Activator of Transcription 3 (STAT3) is a critical regulator of Vascular Endothelial Growth factor (VEGF) expression and activity in cardiac muscle and vascular endothelial cells. We have previously shown that hypoxia-induced activation of STAT3 is a redox-dependent event and can be blocked by inhibitors of NAD(P)H oxidase activity. Here we investigated the specific role of the small G protein Rac-1 in the regulation of hypoxia-induced STAT3 activation in endothelial cells. Human umbilical vein endothelial cells (HUVEC) and human coronary endothelial cells in culture were subjected to 2% oxygen levels for different times (10min, 30min). Rac-1 inhibition was achieved by transfection of ECs with specific siRNA or by treatments of the cells with 75 μ M of the Rac-1 inhibitor NSC23766 (EMD Biosciences). Chromatin immunoprecipitation (ChIP) was conducted to assess STAT3 transcriptional activity. STAT3 phosphorylation and protein-protein association was measured by Western blotting and immunoprecipitation analysis (respectively). We found that inhibition of Rac-1 activity by siRNA or by treatment with NSC23766 blocks STAT3 binding to VEGF promoter in hypoxic conditions compared to treatment of the cells with scramble siRNA or vehicle only. This effect correlated with blockade of hypoxia-induced STAT3 tyrosine phosphorylation at tyrosine 705 and at serine 727. In addition, hypoxia-stimulated Rac-1 binding to STAT3 at 30 minutes and inhibition of Rac-1 activity stimulated STAT3 binding to Protein Inhibitor of STAT3 (PIAS3) responsible for its sumoylation/inactivation. Taken together our results suggest that Rac-1 activity is associated with hypoxia-stimulated STAT3 activation and STAT3-dependent VEGF by regulating its phosphorylation/activation as well its sumoylation via blockade of STAT3 binding to PIAS3. These data disclose a previously uncovered activity of Rac-1 in the regulation of STAT3 inactivation by sumoylation.

Regulation of angiotensin II actions by enhancers and super-enhancers in vascular smooth muscle cells (2017)

Angiotensin II (AngII) promotes hypertension and atherosclerosis by activating growth-promoting and pro-inflammatory gene expression in vascular smooth muscle cells (VSMCs). Enhancers and super-enhancers (SEs) play critical roles in driving disease-associated gene expression. However, enhancers/SEs mediating VSMC dysfunction remain uncharacterized. Here, we show that AngII alters vascular enhancer and SE repertoires in cultured VSMCs in vitro, ex vivo, and in AngII-infused mice aortas in vivo. AngII-induced enhancers/SEs are enriched in binding sites for signal-dependent transcription factors and dependent on key signaling kinases. Moreover, CRISPR-Cas9-mediated deletion of candidate enhancers/SEs, targeting SEs with the bromodomain and extra-terminal domain inhibitor JQ1, or knockdown of overlapping long noncoding RNAs (lncRNAs) blocks AngII-induced genes associated with growth-factor signaling and atherosclerosis. Furthermore, JQ1 ameliorates AngII-induced hypertension, medial hypertrophy and inflammation in vivo in mice. These results demonstrate AngII-induced signals integrate enhancers/SEs and lncRNAs to increase expression of genes involved in VSMC dysfunction, and could uncover novel therapies.
Space Environmental Testing of Thermal Control Foils at Extreme Temperatures (2004)

Our current understanding regarding the evaluation of the thermal endurance and UV radiation stability of two different types of commercially available aromatic polyimides at elevated temperatures is presented. Such materials are typically used as thermal control foils. To characterize the thermal endurance a high vacuum thermal ageing campaign was performed at 350 'C up to 4452 h. During that test the mass loss was found to be higher for the Kapton HN (DuPont, USA)-film than for the Upilex S (UBE Industries, Japan)-film material. Further UV/VIS/NIR transmission and thermo-optical measurements revealed the degradation behaviour of both films versus time at 350 'C. It was found that in general the Upilex S-film degrades at a slower rate. To screen the radiation stability an environmental UV test was performed with samples being simultaneously at 100, 230 and 350 'C. After the test it was noted that the Kapton HN-film shows for all three temperatures a higher mass loss than the Upilex S-film. A non-linear correlation of the activation energies for the mass loss of the Kapton-HN film as a function of temperature was also found. Furthermore, a higher loss of transmittance (UVIVIS) was found for the Kapton HN-film and a higher degradation of the a/E ratio when compared with the Upilex-S-film. For the latter material it seems that this degradation is temperature activated.
The Parallel FDFM Processor Core Approach for Neural Networks (2011)

This paper presents a parallel FDFM (Few DSP blocks and Few block RAMs) processor core approach for implementing a perceptron. In our new approach, a perceptron is implemented a processor core using few DSPs and few block RAMs in the FPGA. This approach is promising because we can obtain high throughput using multiple FDFM cores that work in parallel. Also, even if the FPGA does not have enough remaining space for a perceptron, we can implement it using only few DSP slices and few block RAMs. We have implemented 150 processor cores for perceptrons in a Xilinx Virtex-4 family FPGA XC4SX35-10FF668. The implementation results show that 150 processor cores can be implemented in the FPGA using 150 DPS48 slices, 190 block RAMs, and 11679 slices. It runs in 161.546MHz clock frequency and a single evaluation of 96 nodes perceptron can be performed $10.959\times 10^6$ times per second. We have also implemented in the FPGA board of the Virtex-4 Xtreme DSP development kit and confirmed that our 150 processor cores work correctly.
Impact of Biodiesel Blends on Emissions from a Switching Locomotive (2011)

Biodiesel, a renewable fuel manufactured from vegetable oils and animal fats, has the potential to both reduce fossil fuel use in the nation’s transportation network and improve emissions of regulated pollutants, especially particulate matter. Currently, however, there is minimal data available on the performance of biodiesel and biodiesel blends in most non-road applications, including locomotive diesel engines. In this study, 10% (B10) and 20% (B20) biodiesel blends, created by mixing a soybean oil based biodiesel fuel with ultra-low sulfur diesel, were tested in a switching locomotive owned by the Iowa Interstate Railroad. Each blend was used in the locomotive during standard operations over a 90-day period. Emission testing was performed during static load tests conducted at the beginning and end of these periods. Gaseous emissions were collected using an in-line flow sampler and analyzed for nitrogen oxides, total hydrocarbons, carbon monoxide, carbon dioxide, and oxygen. Fuel consumption and power output were also monitored during the load tests. Increased biodiesel content in the fuel was associated with a reduction in partial combustion products, particularly total hydrocarbons, but increased NOx emissions. A single test comparing B20 and ultra-low sulfur diesel also showed a 35% reduction in soot emissions with the biodiesel blend. No performance or maintenance issues were observed during the 90-day trials, and neither the engine nor its operation was modified in any way, suggesting that these biodiesel blends are viable “drop in” substitutes for petroleum diesel in railroad switching yards from both a performance and air quality standpoint.
Micromechanical Testing of Individual Collagen Fibrils (2006)

A novel method based on AFM was used to attach individual collagen fibrils between a glass surface and the AFM tip, to allow force spectroscopy studies of these. The fibrils were deposited on glass substrates that are partly coated with Teflon AF. A modified AFM tip was used to accurately deposit epoxy glue droplets on either end of the collagen fibril that cross the glass-Teflon AF interface, as to such attach it with one end to the glass and the other end to the AFM tip. Single collagen fibrils have been mechanically tested in ambient conditions and were found to behave reversibly up to stresses of 90 MPa. Within this regime a Young's modulus of 2-7 GPa was obtained. In aqueous media, the collagen fibrils could be tested reversibly up to about 15 MPa, revealing Young's moduli ranging from 0.2 to at most 0.8 GPa.
Genes from mycoparasitic fungi as a source for improving plant resistance to fungal pathogens (1998)

Disease resistance in transgenic plants has been improved, for the first time, by the insertion of a gene from a biocontrol fungus. The gene encoding a strongly antifungal endochitinase from the mycoparasitic fungus Trichoderma harzianum was transferred to tobacco and potato. High expression levels of the fungal gene were obtained in different plant tissues, which had no visible effect on plant growth and development. Substantial differences in endochitinase activity were detected among transformants. Selected transgenic lines were highly tolerant or completely resistant to the foliar pathogens Alternaria alternata, A. solani, Botrytis cinerea, and the soilborne pathogen Rhizoctonia solani. The high level and the broad spectrum of resistance obtained with a single chitinase gene from Trichoderma overcome the limited efficacy of transgenic expression in plants of chitinase genes from plants and bacteria. These results demonstrate a rich source of genes from biocontrol fungi that can be used to control diseases in plants.
Heat release kinetics (2000)

The role of solid-state thermal degradation kinetics in steady-flaming combustion is examined. Expressions for the burning surface temperature, pyrolysis zone depth and fractional mass loss rate are derived from heat transport limited, nonisothermal pyrolysis kinetics. The predicted magnitude of these fire response parameters and their variation with incident heat flux are in qualitative agreement with experimental data from the literature. A material flammability parameter emerges from the analysis that has the units (J/g-K) and significance of a heat release capacity. Published in 2000 by John Wiley & Sons Ltd.
Depression of glutamatergic transmission by nociceptin in the neonatal rat hemisected spinal cord preparation in vitro (1996)

The present study explored the action of nociceptin, the putative endogenous ligand for the orphan opioid receptor (ORL1), on the rat hemisected spinal cord preparation. Electrical stimulation of a dorsal root evokes a glutamatergic population ventral root potential (DR-VRP) in the corresponding ventral root. Low intensity stimulation evokes two A fibre-mediated components; a compound action potential of motoneurones superimposed on a population e.p.s.p. (excitatory postsynaptic potential); at higher stimulus intensities sufficient to activate C fibres a more prolonged population e.p.s.p. is evoked. All three components were depressed by nociceptin in a concentration-dependent manner with IC50 values (s.e.mean) of 119 +/- 2 nM (n = 4), 241 +/- 3 nM (n = 4) and 32 +/- 2 nM (n = 4), respectively. The depressant actions of nociceptin (30 nM and 300 nM) were not reversed by the opioid antagonist naloxone (1 microM). Nociceptin (100 nM and 300 nM) had no effect on the afferent volleys in the dorsal root. Nociceptin therefore appears to be acting as an inhibitory peptide at the spinal level through a naloxone-insensitive opioid receptor.

Solvothermal in Situ Metal/Ligand Reactions:  A New Bridge between Coordination Chemistry and Organic Synthetic Chemistry (2006)

Several important solvothermal (including hydrothermal) in situ metal/ligand reactions and their mechanisms, including dehydrogenative carbon-carbon coupling, hydroxylation of aromatic rings, cycloaddition of organic nitriles with azide and ammonia, transformation of inorganic and organic sulfur, as well as the CuII to CuI reduction, are outlined in this Account. The current progress clearly demonstrates the important potential of such reactions in the crystal engineering of functional coordination compounds and one-pot synthesis of some unusual organic ligands that are inaccessible or not easily obtainable via conventional methods, thereby substantiating our expectation that a new bridge has been created between coordination chemistry and synthetic organic chemistry.
Influence of Rete Testis Fluid on the Metabolism of Testosterone by Cultured Principal Cells Isolated from the Proximal or Distal Caput of the Rat Epididymis (1983)

Principle cells from 120 elutriations were used to improve procedures for culturing cells from the proximal or distal caput epididymidis. The criteria evaluated were metabolism of testosterone (T) to 5 alpha-reduced metabolites and cellular morphology after 6 days of culture. Isolated principal cells (greater than 90% viability) were cultured at 34 degrees C within a floating collagen matrix. Inclusion of transferrin or retinol in the culture medium increased the production of 5 alpha-reduced metabolites. Aggregation of principal cells before entrapment in the collagen matrix resulted in higher production of 5 alpha-reduced metabolites and more cells with a normal find structure than entrapment of dispersed cells in the matrix. Aggregated cells tended to form sheets or clusters, frequently arranged around a central lumen, with junctional complexes between adjacent cells. Cell polarity and morphologic features distinguishing principal cells from the proximal caput and distal caput epididymidis were retained. An average of 91% of the cells in aggregates were morphologically normal on Day 6 of culture in contrast to 5% for the single cells. Utilizing the improved culture procedure, we tested the hypothesis that ovine rete testis fluid (RTF) contains macromolecules which would aid in maintenance of a high rate of T metabolism. Principal cells were cultured in medium supplemented with 0 or 10% RTF, 10% ultrafiltrate of RTF (less than 10,000 daltons), or 10% newborn calf serum (NCS). Conversion of [3H]T to 5 alpha-reduced metabolites by cells from the proximal caput was twice that in cells from the distal caput on Day 6 of culture. Inclusion in the culture medium of 10% RTF or 10% NCS, but not 10% ultrafiltrate of RTF, increased (P less than 0.05) the production of 5 alpha-reduced metabolites by cells from both regions. We conclude that macromolecules in RTF or NCS are beneficial to maintenance of the ability to metabolize T by cultured principal cells, especially those from the proximal caput.
Automating accessibility: the dynamic keyboard (2003)

People with motor disabilities may need to adjust the configuration of their input devices, but often find this an obscure and difficult process. The Dynamic Keyboard exemplifies a potential solution. It continuously adjusts fundamental keyboard accessibility features to suit the requirements of the current user, based on a keyboard use model. Early field results indicate that users have not chosen to take control of these accessibility features from the Dynamic Keyboard, and that a variety of settings are being used. A more detailed ongoing study suggests that automatic adjustment of the key repeat delay feature is acceptable to users, while the debounce feature may not be appropriate for dynamic adjustment.
Substance P responsiveness of smooth muscle cells is regulated by the integrin ligand, thrombospondin. (1996)

The extracellular factors that determine a cell's responsiveness to neurotransmitters are of particular relevance for pharmacologically diverse cell types such as neurons and smooth muscle. We previously demonstrated that matrix-associated factors are capable of dramatically and specifically suppressing the responsiveness of smooth muscle to the neuropeptide, substance P. We now demonstrate that this influence of extracellular matrix on the pharmacological phenotype of smooth muscle cells can be blocked specifically by an Arg-Gly-Asp (RGD)-containing antagonist of integrins. Of a battery of integrin ligands tested, only thrombospondin mimicked the effect of the extracellular matrix on substance P responsiveness. This effect of thrombospondin was dose dependent, RGD sensitive, and blocked by an antibody directed against the RGD-containing region of thrombospondin. Because the mRNA for thrombospondin is present in the cells of the chicken amnion, this extracellular factor may normally suppress substance P responsiveness in amniotic smooth muscle. The results suggest a role for matrix-associated integrin ligands in the regulation of cellular responses to specific neurotransmitters and hormones and in the development and maintenance of tissue-specific pharmacological properties.
