Disilicate-Assisted Iron Electrolysis for Sequential Fenton-Oxidation and Coagulation of Aqueous Contaminants (2017)

Sodium disilicate (SD), an inorganic and environmentally friendly ligand, is introduced into the conventional iron electrolysis system to achieve an oxidizing Fenton process to degrade organic pollutants. Electrolytic ferrous ions, which are complexed by the disilicate ions, can chemically reduce dioxygen molecules via consecutive reduction steps, producing H<sub>2</sub>O<sub>2</sub> for the Fenton-oxidation of organics. At the near-neutral pH (from 6 to 8), the disilicate-Fe(II) complexes possess strong reducing capabilities; therefore, a near-neutral pH rather than an acid condition is preferable for the disilicate-assisted iron electrolysis (DAIE) process. Following the DAIE process, the different complexing capacities of disilicate for ferrous/ferric ions and calcium ions can be used to break the disilicate-iron complexes. The addition of CaO or CaCl<sub>2</sub> can precipitate ferrous/ferric ions, disilicates and possibly heavy metals in the wastewater. Compared to previously reported organic and phosphorus ligands, SD is a low-cost inorganic agent that does not lead to secondary pollution, and would not compete with the target organic pollutants for •OH; therefore, it would greatly expand the application fields of the O<sub>2</sub> activation process. The combination of DAIE and CaO treatments is envisioned to be a versatile and affordable method for treating wastewater with complicated pollutants (e.g., mixtures of biorefractory organics and heavy metals).

In vivo delivery of siRNA to key transcipts of fibrogenesis in lipid-like carriers inhibits development liver fibrosis (2012)

Introduction: Antifibrotic therapies have to be specific (on target), efficient and free of major side effects. C12–200 lipid-like particles (LPs) consisting of epoxide terminated alkyl chains and secondary amine monomers permit efficient delivery of siRNA, minimizing interference with blood cells and plasma and being devoid of side effects. Intravenous C12–200 LPs allow efficient and safe delivery of small interfering RNAs (siRNAs) to the liver (Akinc et al, Nat Biotechnol 2008).
Low‐Cost Volumetric 3D Printing of High‐Precision Miniature Lenses in Seconds (Advanced Optical Materials 17/2022) (2022)

Targeting the fast prototyping and massive production of complicated lenses, Zhiwei Zhu and co-workers report a low-cost volumetric 3D printing method for the ultra-fast and high-precision fabrication of miniature lenses with sub-nanometric roughness (see article number 2200488). The complex-shaped lenses are generated by the volumetric projection stereolithography and corrected by introducing an iterative learning scheme. Super-smooth surfaces are guaranteed by the meniscus equilibrium effect.

Sequentially designed compressed sensing (2012)

A sequential adaptive compressed sensing procedure for signal support recovery is proposed and analyzed. The procedure is based on the principle of distilled sensing, and makes used of sparse sensing matrices to perform sketching observations able to quickly identify irrelevant signal components. It is shown that adaptive compressed sensing enables recovery of weaker sparse signals than those that can be recovered using traditional non-adaptive compressed sensing approaches.
Compact MIMO Microstrip Antennas for USB Dongle Operating in 2.5–2.7 GHz Frequency Band (2012)

This paper considers design of microstrip MIMO antennas for an LTE/WiMAX USB dongle operating in the 2.5–2.7 GHz frequency band. The MIMO system includes two antenna elements with an additional requirement of high isolation between them that is especially difficult to realize due to size limitations of a USB dongle. Three approaches to achieve the needed system characteristics using microstrip PCB antennas are proposed. For the first design, high port-to-port isolation is achieved by using a decoupling techniques based on a direct connection of the antenna elements. For the second approach, high port-to-port isolation of the MIMO antenna system is realized by a lumped decorrelation capacitance between antenna elements feeding points. The third proposed antenna system does not use any special techniques, and high port-to-port isolation is achieved by using only the properties of a developed printed inverted-F antenna element. The designed MIMO antenna systems have the return loss S 11 and the insertion loss S 21 bandwidths of more than 200 MHz at the −8 dB level with the correlation coefficient lower than 0.1 and exhibit pattern diversity when different antenna elements are excited. Experimental measurements of the fabricated antenna systems proved the characteristics obtained from electromagnetic simulation.
MiR-34a/c-Dependent PDGFR-α/β Downregulation Inhibits Tumorigenesis and Enhances TRAIL-Induced Apoptosis in Lung Cancer (2013)

Lung cancer is the leading cause of cancer mortality in the world today. Although some advances in lung cancer therapy have been made, patient survival is still poor. MicroRNAs (miRNAs) can act as oncogenes or tumor-suppressor genes in human malignancy. The miR-34 family consists of tumor-suppressive miRNAs, and its reduced expression has been reported in various cancers, including non-small cell lung cancer (NSCLC). In this study, we found that miR-34a and miR-34c target platelet-derived growth factor receptor alpha and beta (PDGFR-α and PDGFR-β), cell surface tyrosine kinase receptors that induce proliferation, migration and invasion in cancer. MiR-34a and miR-34c were downregulated in lung tumors compared to normal tissues. Moreover, we identified an inverse correlation between PDGFR-α/β and miR-34a/c expression in lung tumor samples. Finally, miR-34a/c overexpression or downregulation of PDGFR-α/β by siRNAs, strongly augmented the response to TNF-related apoptosis inducing ligand (TRAIL) while reducing migratory and invasive capacity of NSCLC cells.
Identified-particle production in Xe + Xe collisions at sNN=5.44 TeV using a multiphase transport model (2019)

Xe+Xe collisions at relativistic energies provide us with an opportunity to study a possible system with deconfined quarks and gluons, whose size is in between those produced by $p+p$ and Pb+Pb collisions. In the present work, we have used a multiphase transport (AMPT) model with nuclear deformation to study the identified particle production, such as (${\ensuremath{\pi}}^{+}+{\ensuremath{\pi}}^{\ensuremath{-}}$), (${K}^{+}+{K}^{\ensuremath{-}}$), ${K}_{s}^{0}$, ($p+\overline{p}$), $\ensuremath{\phi}$, and ($\mathrm{\ensuremath{\Lambda}}+\overline{\mathrm{\ensuremath{\Lambda}}}$) in Xe+Xe collisions at $\sqrt{{s}_{NN}}=5.44\phantom{\rule{0.28em}{0ex}}\mathrm{TeV}$. We study the $p{}_{\mathrm{T}}$ spectra, integrated yield, and $p{}_{\mathrm{T}}$-differential and $p{}_{\mathrm{T}}$-integrated particle ratios to (${\ensuremath{\pi}}^{+}+{\ensuremath{\pi}}^{\ensuremath{-}}$) and (${K}^{+}+{K}^{\ensuremath{-}}$) as a function of collision centrality. The particle ratios are focused on strange to nonstrange ratios and baryon to meson ratios. The effect of deformations has also been highlighted by comparing our results to the nondeformation case. We have also compared the results from AMPT string melting and the AMPT default version to explore possible effects of the coalescence mechanism. We observe that the differential particle ratios show strong dependence on centrality while the integrated particle ratios show no centrality dependence. We give a thermal model estimation of chemical freeze-out temperature and the Boltzmann-Gibbs Blast Wave analysis of kinetic freeze-out temperature and collective radial flow in Xe+Xe collisions at $\sqrt{{s}_{NN}}=5.44\phantom{\rule{0.28em}{0ex}}\mathrm{TeV}$.
Adaptive FIR filtering based on bounded error constraints (2003)

The performance of adaptive FIR algorithms in the presence of bounded disturbances, in particular, algorithms based on gradient mean squared error (MSE) estimators, gradient estimators with dead-zone thresholds, and set membership estimators, is examined. A simple example of the bursting phenomenon is given, and the algorithms and their properties are described. Analytical results on the performance of these estimators are also given. An algorithm that provides both MSE and instantaneous maximum amplitude error (in the limsup sense) performance guarantees is proposed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
A Comprehensive Wind Power Forecasting System Integrating Artificial Intelligence and Numerical Weather Prediction (2020)

The National Center for Atmospheric Research (NCAR) recently updated the comprehensive wind power forecasting system in collaboration with Xcel Energy addressing users’ needs and requirements by enhancing and expanding integration between numerical weather prediction and machine-learning methods. While the original system was designed with the primary focus on day-ahead power prediction in support of power trading, the enhanced system provides short-term forecasting for unit commitment and economic dispatch, uncertainty quantification in wind speed prediction with probabilistic forecasting, and prediction of extreme events such as icing. Furthermore, the empirical power conversion machine-learning algorithms now use a quantile approach to data quality control that has improved the accuracy of the methods. Forecast uncertainty is quantified using an analog ensemble approach. Two methods of providing short-range ramp forecasts are blended: the variational doppler radar analysis system and an observation-based expert system. Extreme events, specifically changes in wind power due to high winds and icing, are now forecasted by combining numerical weather prediction and a fuzzy logic artificial intelligence system. These systems and their recent advances are described and assessed.
Role of Coagulation Factors in Cerebral Venous Sinus and Cerebral Microvascular Thrombosis (2010)

Thrombin promotes while the APC pathway blunts thrombus formation in an experimental model of cerebral venous sinus thrombosis. TF involvement is more evident in cerebral microvascular thrombogenesis, with endothelial cell-associated TF mediating this response in venules, but not arterioles.
Maternal vaccinations coverage and reasons for non-compliance - A cross-sectional observational study (2020)

Abstract Background: Maternal influenza and pertussis vaccinations have been proven safe and effective in reducing maternal and infant morbidity and mortality. Though recommended, not all pregnant women receive these important vaccines. We aimed to evaluate the vaccine coverage of maternal immunization in pregnancy for seasonal influenza and acellular pertussis and elucidate the reasons for non-vaccination among pregnant women. The secondary objective was to describe factors that affect vaccine uptake. Methods: A cross sectional observational study using anonymous questionnaires distributed to women in the maternity ward or pregnant women hospitalized in the high-risk ward, between Nov 2017 and June 2018, In an Israeli tertiary hospital. Results: Of 321 women approached, 313 were eligible, with a total of 290 women completing the questionnaire (92.6%). We found a 75.9% (95% CI 71-81) and 34.5% (95% CI 29-40) vaccination rate for pertussis and influenza vaccines, respectively. The most prominent reason for not receiving the pertussis vaccine was being under-informed (24%). Influenza vaccine was not received mainly due to concerns about vaccine efficacy (28%). Other factors influencing vaccine uptake included education, prior childbirth and vaccine recommendations made by the provider. Conclusion: Although maternal vaccination of pertussis and influenza is officially recommended, vaccine uptake is suboptimal. Our study suggests a central role for medical providers in diminishing the concerns about safety and efficacy, and presents novel factors influencing compliance rates, like seasonality and number of prior births.
Characterization and Inhibitor Studies of Chitinases from a Parasitic Blowfly (Lucilia cuprina), a Tick (Boophilus microplus), an Intestinal Nematode (Haemonchus contortus) and a Bean (Phaseolus vulgaris) (1996)

The molecular weight pattern and the stage-specific activities of chitinases from the blowfly Lucilia cuprina, the tick Boophilus microplus and the intestinal nematode Haemonchus contortus were examined. Chitinolytic enzymes could be detected in all parasite species tested, but the activity was different between the stages. Highest chitinolytic titers were found in blowfly pupae (83 kDa, 118 kDa), hatching larvae of ticks (58 kDa, 94 kDa) and nematode eggs (43 kDa). Leaves from ethylene-treated bean plants Phaseolus vulgaris expressed two basic Class I chitinases (Ia, Ib) of 34 kDa, differing in their amino acid sequences at residue 33 and 34 (Ia: glycine, proline; Ib: lysine, aspartic acid). Inhibitor studies with blowfly pupae revealed that allosamidin (IC50=0·32 (±0·02) μM) was by far the best inhibitor when compared with various amino sugar derivatives. This compound also inhibited chitinases from tick larvae (IC50=0·69(±0·10) μM) and nematode eggs (IC50=0·048(±0·0045) μM) specifically. Whereas Class Ia chitinase from bean leaves was inhibited only up to 18% by 10 μM allosamidin, it had an IC50 of 1(±0·14) μM for the Ib type, which is the first plant chitinase described to be highly sensitive to allosamidin.
Make TCP Great (again?!) in Cellular Networks: A Deep Reinforcement Learning Approach. (2019)

Can we instead of designing just another new TCP, design a TCP \textit{plug-in} which can boost the performance of the existing/future TCP designs in cellular networks? To answer this question, we introduce DeepCC plug-in. DeepCC leverages deep reinforcement learning (DRL), a modern decision-making tool, to steer TCP toward achieving applications' desired delay and high throughput in a highly dynamic network such as the cellular network. The fact that DeepCC does not try to reinvent/replace TCP but aims to boost the performance of it differentiates it from the most (if not all) of the existing reinforcement learning (RL) systems where RL systems are considered clean-slate alternative designs replacing the traditional ones. 
We used DeepCC plug-in to boost the performance of various old and new TCP schemes including TCP Cubic, Google's BBR, TCP Westwood, and TCP Illinois in cellular networks. Through both extensive trace-based evaluations and in-field tests, we show that not only DeepCC can significantly improve the performance of TCP, but also after accompanied by DeepCC, these schemes can outperform state-of-the-art TCP protocols including Aurora, Sprout, Verus, C2TCP, Copa, Indigo, Remy, PCC-Vivace, and LEDBAT in cellular networks.
Evaluation of the damage suppression effect of Ti-Ni shape memory alloy foils embedded in carbon fiber reinforced plastic laminates (2005)

In this research, shape memory alloy (SMA) foils were embedded into carbon fiber reinforced plastic (CFRP) cross-ply laminates. When the tensile pre-strained SMA foil is heated, the SMA produces appropriate compressive stress (recovery stress) to suppress the transverse cracks in the laminates. In order to investigate the damage suppression effect, tensile loading–unloading tests were conducted for the CFRP cross-ply laminates. The test results implied that the recovery stress of embedded SMA foil suppressed the occurrence and the progress of the transverse crack. Then, to confirm that the damage suppression effect was caused by the embedded SMA foil, the one-dimensional (1D) shear-lag model considering the behavior of SMA was newly derived. Using this model, the progress of transverse crack density was predicted probabilistically. The simulation results showed the same tendency as the experimental results. As a result, it was proved that the embedment of SMA foils into CFRP laminates is effective to suppress the occurrence and growth of the transverse cracks.
A study on a robot arm driven by three-dimensional trajectories predicted from non-invasive neural signals (2015)

A robot arm driven by 3D trajectories predicted from non-invasive neural signals was implemented, and reaching and grasping motions were performed. In most cases, the robot closely approached the target, but the success rate was not very high because the non-invasive neural signal is less accurate. However the success rate could be sufficiently improved for practical applications by using additional sensors. Robot arm control based on hand trajectories predicted from EEG would allow for portability, and the performance with EEG was comparable to that with MEG.
Binary Diffusion Coefficients of the Liquid Organic Hydrogen Carrier System Dibenzyltoluene/Perhydrodibenzyltoluene (2015)

Liquid organic hydrogen carrier (LOHC) systems constitute a very promising concept for future hydrogen storage and logistics. The concept builds on the conversion of excess renewable energy to hydrogen via electrolysis followed by reversible catalytic hydrogenation/dehydrogenation of a diesel-like organic carrier molecule. For an ideal design of the catalytic process, insight into reaction mechanisms and kinetics but also precise knowledge on mass transport properties are necessary. In the present study, binary diffusion coefficients in selected binary LOHC mixtures with five different compositions of perhydrodibenzyltoluene (H18-LOHC) and dibenzyltoluene (LOHC) were measured by dynamic light scattering (DLS). The compositions were defined by mixing appropriate amounts of LOHC and H18-LOHC to realize different hydrogenation degrees of the LOHC. Binary diffusion coefficients were investigated over a temperature range from (264 to 571) K with an absolute uncertainty of (3 to 25) %. Moreover, an empirical equation describing the binary diffusion coefficients of all five mixture compositions over the complete temperature range with a root-mean-square deviation of less than 3 % was established. It was observed that the binary diffusion coefficient is independent of the hydrogenation degree of LOHC at temperatures above 430 K. For lower temperatures, the binary diffusion coefficient increases with decreasing degree of hydrogenation.

Su2076 Bile Acid Diarrhoea Masquerades As Diarrhoea-Predominant Irritable Bowel Syndrome: Results From a Dual Centre Prospective Study (2014)

Introduction: A major theme in functional bowel disorders (FBD) such as irritable bowel syndrome (IBS) is that psychological/psychiatric problems have a pathogenic role, based both on the observation that patients with FBD are more anxious and depressed than healthy control, as well as research linking stress and depression to altered gastrointestinal sensory and motor function. However, recent experimental and epidemiological studies suggest that primary visceral disturbances can lead secondarily to persistent behavioral and emotional abnormalities. The aims of the present study were to test the hypothesis that mild chemical irritation of the colon of neonatal mice can produce changes in visceral hypersensitivity and psychological behaviors that persist into adulthood. Methods: Ten-day old C57BL/6 mouse pups received an intracolonic infusion of 20 μl of 0.5% acetic acid (IBS) or saline (control) to mimic a previously validated model of IBS in rats based on neonatal visceral irritation. Psychological behaviors and pain sensitivity of the colon were assessed when these mice were 8-14 weeks of age. Anxiety-like behaviors were tested using elevated plus maze and open field tests. Depression-like behavior was tested by the forced swim test. Colonic hypersensitivity to graded colorectal balloon distension (15, 30, 50 and 70mmHg) was determined by visceromotor responses (VMR) measured by electromyography of external oblique muscle. Resutls: Neonatal colorectal infusion of acetic acid but not saline significantly increased electromyographic activity in response to all of pressure colorectal distension in adults, suggesting the persistence of colonic hypersensitivity. In the elevated plus maze and open field tests, IBS mice showed a significant reduction in time spent in the open arms of elevated plus maze (control: 73.04±5.26s vs IBS: 53.54±6.53s, p<0.05) and in the center of the open field (control: 73.99±6.42s vs IBS: 37.32±4.62s, p<0.05), suggesting an anxietylike phenotype. IBS mice also showed a significant increase in immobility in the forced swim test (control: 90.05±12.08s vs IBS: 140.43±20.06s, p<0.05), suggesting an increase in depression-like behavior. Conclusion: The present results demonstrate that transient colonic irritation in the neonatal period can induce long-lasting depression-like and anxietylike behaviors. These findings provide a new paradigm for the psychological co-morbidity in functional bowel disorders.
Edge-emitting quantum well laser with integrated intracavity electrostatic gate (1997)

Ridge waveguide, edge-emitting single quantum well GaAs lasers with an integrated gating electrode have been fabricated. These devices integrate a MESFET structure with the laser PN junction so that the SBD (Schottky barrier diode) depletion layer can be used for transverse current confinement in the laser. Device fabrication was very simple requiring only an anisotropic etch for waveguide definition followed by a single self-aligned contact deposition step. The Schottky barrier depletion layers on either side of the ridge waveguide act to confine free carriers. This structure allows for separation of the optical and electrical confinement in the transverse direction without requiring complex fabrication. The device demonstrated modulation of the pulsed lasing threshold with gate control voltage on a 30 micron wide ridge. Above threshold, increasing power output with increasing gate voltage was demonstrated with negligible gate current. The multimode lasing spectrum showed that the increased power output occurred for all modes with no shift in the mode wavelengths to within the resolution of the measurement system.
