Low Temperature Tolerant Organohydrogel Electrolytes for Flexible Solid‐State Supercapacitors (2018)

Abstract Gel electrolytes are attracting growing interest in the field of flexible solid supercapacitors. So far, hydrogel electrolytes have been widely investigated, and high performance flexible supercapacitors based on these electrolytes have been realized. However, conventional hydrogel electrolytes contain massive solvent water, inevitably freeze and restrict ion transport at subzero temperatures, which fundamentally limits the utilization of supercapacitors in extreme low temperatures. A new organohydrogel electrolyte that successfully brings the advantages of outstanding flexibility and ionic conductivity at low temperatures by using H 2 O/ethylene glycol as a dispersion medium is reported here. When applying the antifreezing organohydrogel electrolyte, the flexible solid supercapacitor with carbon nanotube paper electrodes (≈0.5 × 2.2 cm 2 ) exhibits stable electrochemical performance (70.6% capacitance retained at −40 °C) and excellent cycling stability (only 11.7% capacitance decay over 5000 charge/discharge cycles at −20 °C.) at low temperatures, representing the excellent low temperature tolerance. Meanwhile, the supercapacitor devices offer remarkable flexible performance under consecutive bending conditions. It is anticipated that the low temperature tolerant organohydrogel electrolyte may be a promising gel electrolyte for the next generation of flexible solid supercapacitors for using at low temperature environments.
Intercomparison of Vertical Structure of Storms Revealed by Ground‐Based (NMQ) and Spaceborne Radars (CloudSat‐CPR and TRMM‐PR) (2013)

Spaceborne radars provide great opportunities to investigate the vertical structure of clouds and precipitation. Two typical spaceborne radars for such a study are the W-band Cloud Profiling Radar (CPR) and Ku-band Precipitation Radar (PR), which are onboard NASA's CloudSat and TRMM satellites, respectively. Compared to S-band ground-based radars, they have distinct scattering characteristics for different hydrometeors in clouds and precipitation. The combination of spaceborne and ground-based radar observations can help in the identification of hydrometeors and improve the radar-based quantitative precipitation estimation (QPE). This study analyzes the vertical structure of the 18 January, 2009 storm using data from the CloudSat CPR, TRMM PR, and a NEXRAD-based National Mosaic and Multisensor QPE (NMQ) system. Microphysics above, within, and below the melting layer are studied through an intercomparison of multifrequency measurements. Hydrometeors' type and their radar scattering characteristics are analyzed. Additionally, the study of the vertical profile of reflectivity (VPR) reveals the brightband properties in the cold-season precipitation and its effect on the radar-based QPE. In all, the joint analysis of spaceborne and ground-based radar data increases the understanding of the vertical structure of storm systems and provides a good insight into the microphysical modeling for weather forecasts.
Multifunctional Structural Supercapacitor Composites Based on Carbon Aerogel Modified High Performance Carbon Fiber Fabric (2013)

A novel multifunctional material has been designed to provide excellent mechanical properties while possessing a high electrochemical surface area suitable for electrochemical energy storage: structural carbon fiber fabrics are embedded in a continuous network of carbon aerogel (CAG) to form a coherent but porous monolith. The CAG-modification process was found to be scalable and to be compatible with a range of carbon fiber fabrics with different surface properties. The incorporation of CAG significantly increased the surface area of carbon fiber fabrics, and hence the electrochemical performance, by around 100-fold, resulting in a CAG-normalized specific electrode capacitance of around 62 F g–1, determined by cyclic voltammetry in an aqueous electrolyte. Using an ionic liquid (IL) electrolyte, the estimated energy density increased from 0.003 to 1 Wh kg–1, after introducing the CAG into the carbon fiber fabric. ‘Proof-of-concept’ multifunctional structural supercapacitor devices were fabricated using an IL-modified solid-state polymer electrolyte as a multifunctional matrix to provide both ionic transport and physical support for the primary fibers. Two CAG-impregnated carbon fabrics were sandwiched around an insulating separator to form a functioning structural electrochemical double layer capacitor composite. The CAG-modification not only improved the electrochemical surface area, but also reinforced the polymer matrix surrounding the primary fibers, leading to dramatic improvements in the matrix-dominated composite properties. Increases in in-plane shear strength and modulus, of up to 4.5-fold, were observed, demonstrating that CAG-modified structural carbon fiber fabrics have promise in both pure structural and multifunctional energy storage applications.
Fast and sound two-step algorithms for multiple alignment of nucleic sequences (2002)

The authors report on their work on multiple alignment of biological sequences. The observation of actual alignments has lead the authors to formulate heuristics from which they have derived new and efficient algorithms. These two algorithms are very fast and give reasonably good results. They work in two steps: blocks are found in the sequences, and then the sequences are aligned between the blocks. Strong and sound hypotheses made at every step, as well as a new representation of blocks, yield high efficiency of the resulting algorithms.
PLAID: a public dataset of high-resoultion electrical appliance measurements for load identification research (2014)

We introduce the Plug-Level Appliance Identification Dataset (PLAID), a public and crowd-sourced dataset for load identification research consisting of short voltage and current measurements (in the order of a few seconds) for different residential appliances. The goal of PLAID is to provide a public library for high-resolution appliance measurements that can be integrated into existing or novel appliance identification algorithms. PLAID currently contains measurements for more than 200 different appliance instances, representing 11 appliance classes, and totaling more than a thousand records. In this demo we summarize the existing dataset, demonstrate how new records can be added to the library using a web interface and, finally, walk through a live example of how the library can be integrated into an existing non-intrusive load monitoring (NILM) algorithm framework.
Versatile Occupant Analysis Model (V.O.A.M) for Frontal Impacts Using LS-DYNA and MADYMO (2005)

<div class="htmlview paragraph">Regulations implemented by safety commissions throughout the world have resulted in extensive physical testing to protect the occupants during frontal impact events. Significant prototype and test costs aimed at optimizing structure and restraint systems are associated with meeting these regulations. To help reduce development costs, Computer Aided Engineering (CAE) is often applied. LS-DYNA [<span class="xref">1</span>] coupled with MADYMO [<span class="xref">2</span>] is widely used in crash and occupant safety simulation. An analysis technique which utilized a single model to design and optimize interiors (instrument panel, seats, visor, steering wheel, steering column) and restraints (airbag, seatbelts, retractor, pre-tensioner) was developed. The single model concept captures the global structural kinematics through minimal vehicle representation. Global vehicle modes such as pitch and roll can be represented by applying prescribed motion boundary conditions extracted from full vehicle models.

EigenSkin (2002)

We present a technique which allows subtle nonlinear quasi-static deformations of articulated characters to be compactly approximated by data-dependent eigenbases which are optimized for real time rendering on commodity graphics hardware. The method extends the common Skeletal-Subspace Deformation (SSD) technique to provide efficient approximations of the complex deformation behaviours exhibited in simulated, measured, and artist-drawn characters. Instead of storing displacements for key poses (which may be numerous), we precompute principal components of the deformation influences for individual kinematic joints, and so construct error-optimal eigenbases describing each joint's deformation subspace. Pose-dependent deformations are then expressed in terms of these reduced eigenbases, allowing precomputed coefficients of the eigenbasis to be interpolated at run time. Vertex program hardware can then efficiently render nonlinear skin deformations using a small number of eigendisplacements stored in graphics hardware. We refer to the final resulting character skinning construct as the model's EigenSkin. Animation results are presented for a very large nonlinear finite element model of a human hand rendered in real time at minimal cost to the main CPU.
Effect of smoking on serum RANKL and OPG in sex, age and clinically matched supportive‐therapy periodontitis patients (2007)

Bone loss in smoker-related periodontitis patients may be partially explained by suppression of OPG production.
Viscosity of a dense suspension in Couette flow (2007)

We study the rheology of a granular paste, i.e. a dense suspension of non-Brownian particles, quantitatively at steady state, in a cylindrical Couette cell. Previous studies have shown a discrepancy between local and global measurements of the viscosity for these materials, making it impossible to predict their resistance to flow. Using both MRI investigation techniques and classical rheology studies, we show that agreement between local and global measurements can be obtained, provided the migration of particles inside the gap is taken into account. As found by Leighton & Acrivos ( J. Fluid Mech. vol. 181, 1987, p. 415), the migration leads to a particle density gradient in the flow, the highly sheared regions being less dense in particles. Here, by comparing the local viscosity and particle density measurements from MRI with the macroscopic relation between viscosity and the volume fraction, it is shown that global and local measurements agree with each other. This consequently allows us to define a viscosity for dense suspensions.
Photoresist thin-film effects on alignment process capability (1993)

Two photoresists were selected for alignment characterization based on their dissimilar coating properties and observed differences on alignment capability. The materials are Dynachem OFPR-800 and Shipley System 8. Both photoresists were examined on two challenging alignment levels in a submicron CMOS process, a nitride level and a planarized second level metal. An Ultratech Stepper model 1500 which features a darkfield alignment system with a broadband green light for alignment signal detection was used for this project. Initially, statistically designed linear screening experiments were performed to examine six process factors for each photoresist: viscosity, spin acceleration, spin speed, spin time, softbake time, and softbake temperature. Using the results derived from the screening experiments, a more thorough examination of the statistically significant process factors was performed. A full quadratic experimental design was conducted to examine viscosity, spin speed, and spin time coating properties on alignment. This included a characterization of both intra and inter wafer alignment control and alignment process capability. Insight to the different alignment behavior is analyzed in terms of photoresist material properties and the physical nature of the alignment detection system.
Customer purchase prediction through machine learning (2018)

Due to today’s transition from visiting physical stores to online shopping, predicting customer behavior in the context of e-commerce is gaining importance. It can in- crease customer satisfaction and sales, resulting in higher conversion rates and a competitive advantage, by facilitating a more personalized shopping process. By uti- lizing clickstream and supplementary customer data, models for predicting customer behavior can be built. This study analyzes machine learning models to predict a pur- chase, which is a relevant use case as applied by a large German clothing retailer. Next, to comparing models this study further gives insight into the performance dif- ferences of the models on sequential clickstream and the static customer data, by conducting a descriptive data analysis and separately training the models on the dif- ferent datasets. The results indicate that a Random Forest algorithm is best suited for the prediction task, showing the best performance results, reasonable latency, of- fering comprehensibility and a high robustness. Regarding the different data types, models trained on sequential session data outperformed models trained on the static customer data by far. The best results were obtained when combining both datasets.
Small astigmatism, high power and low noise 0.78 µm self-aligned lasers (1989)

0.78 µm self-aligned AlGaAs lasers have been developed for optical disc recording. The lasers have shown a small astigmatism (<3 µm), low-noise characteristics (RIN < −126 dB/Hz at 3 mW) and stable 30 mW operation (over 1800 hours at 50°C).
Gastric secretion (2004)

An improved understanding of the pathways and mechanisms regulating gastric acid secretion should lead to the development of novel therapies to prevent and treat acid-peptic disorders as well as circumvent the adverse effects of currently used antisecretory medications such as the acid rebound observed after discontinuation of proton pump inhibitors.
Application of fourier analysis to the visibility of gratings (1968)

1. The contrast thresholds of a variety of grating patterns have been measured over a wide range of spatial frequencies.2. Contrast thresholds for the detection of gratings whose luminance profiles are sine, square, rectangular or saw-tooth waves can be simply related using Fourier theory.3. Over a wide range of spatial frequencies the contrast threshold of a grating is determined only by the amplitude of the fundamental Fourier component of its wave form.4. Gratings of complex wave form cannot be distinguished from sine-wave gratings until their contrast has been raised to a level at which the higher harmonic components reach their independent threshold.5. These findings can be explained by the existence within the nervous system of linearly operating independent mechanisms selectively sensitive to limited ranges of spatial frequencies.
Facile Preparation of Conjugated Dienones from Conjugated Enones (1993)

Conjugated dienones were synthesized from the conjugated enones by the treatment with TIPSOTf in the presence of Et3N, followed by oxidation with Pd(OAc)2 in the presence of K2CO3.
Multiple spatially related pharmacophores define small molecule inhibitors of OLIG2 in glioblastoma (2015)

Transcription factors (TFs) are a major class of protein signaling molecules that play key cellular roles in cancers such as the highly lethal brain cancer-glioblastoma (GBM). However, the development of specific TF inhibitors has proved difficult owing to expansive protein-protein interfaces and the absence of hydrophobic pockets. We uniquely defined the dimerization surface as an expansive parental pharmacophore comprised of several regional daughter pharmacophores. We targeted the OLIG2 TF which is essential for GBM survival and growth, we hypothesized that small molecules able to fit each subpharmacophore would inhibit OLIG2 activation. The most active compound was OLIG2 selective, it entered the brain, and it exhibited potent anti-GBM activity in cell-based assays and in pre-clinical mouse orthotopic models. These data suggest that (1) our multiple pharmacophore approach warrants further investigation, and (2) our most potent compounds merit detailed pharmacodynamic, biophysical, and mechanistic characterization for potential preclinical development as GBM therapeutics.

Treatment of Sugar Waste Water by Electrocoagulation (2013)

Sugar industry plays an important role in the economy of India by way of farming and creation of employment. The by-products of sugar mills are also used as raw materials in different industry. However sugar mill have a great environmental impact upon the surrounding environment. The change of water chemistry is the main associated environmental impact of discharging sugar mill’s effluent on an open water body. The effluents are causing odor nuisance during decomposition and disturbed the plant, human and animal life. Due this an economical treatment has been introduced that is known to be electrochemical process. To treat the sugar industry wastewater aluminium plate was used as electrode material. It has been shown that the removal efficiency of COD increased with the increasing applied current density, increasing wastewater flow rate and polyelectrolyte addition. The results indicate that electrocoagulation is very efficient and able to achieve 84.2% COD removal and over 99% color removal in 90 min at 40 mA/cm2 and wastewater flow rate of 1000ml/min.
Infections Caused by<i>Scedosporium</i>spp (2008)

Scedosporium spp. are increasingly recognized as causes of resistant life-threatening infections in immunocompromised patients. Scedosporium spp. also cause a wide spectrum of conditions, including mycetoma, saprobic involvement and colonization of the airways, sinopulmonary infections, extrapulmonary localized infections, and disseminated infections. Invasive scedosporium infections are also associated with central nervous infection following near-drowning accidents. The most common sites of infection are the lungs, sinuses, bones, joints, eyes, and brain. Scedosporium apiospermum and Scedosporium prolificans are the two principal medically important species of this genus. Pseudallescheria boydii, the teleomorph of S. apiospermum, is recognized by the presence of cleistothecia. Recent advances in molecular taxonomy have advanced the understanding of the genus Scedosporium and have demonstrated a wider range of species than heretofore recognized. Studies of the pathogenesis of and immune response to Scedosporium spp. underscore the importance of innate host defenses in protection against these organisms. Microbiological diagnosis of Scedosporium spp. currently depends upon culture and morphological characterization. Molecular tools for clinical microbiological detection of Scedosporium spp. are currently investigational. Infections caused by S. apiospermum and P. boydii in patients and animals may respond to antifungal triazoles. By comparison, infections caused by S. prolificans seldom respond to medical therapy alone. Surgery and reversal of immunosuppression may be the only effective therapeutic options for infections caused by S. prolificans.

Use of an Enzyme Immunoassay to Detect Serum IgG Antibodies to Haemophilus ducreyi (1988)

An experimental enzyme immunoassay (EIA) for detecting serum IgG antibody to Haemophilus ducreyi was developed using an ultrasonicated whole-cell antigen. The mean optical densities (OD) for sera from men with proven chancroid from Nairobi (47 patients) and Bangkok (72 patients) were significantly higher than those obtained from Nairobi men with genital ulcers not due to H. ducreyi, from Nairobi men with urethritis, from pregnant women in Nairobi, and from European men with sexually transmitted disease. When an OD of 0.500 was taken as the cutoff value, 89% and 55% of men with proven chancroid in Nairobi and Bangkok, respectively, were positive for H. ducreyi antibody, as compared with 2%-17% in the control groups. A rise in OD was observed in five of 18 patients with clinical chancroid. These results confirm the development of circulating antibodies in chancroid and suggest that this EIA may be useful for the diagnosis and epidemiological study of H. ducreyi infection.
