Predicting Smartphone Battery Life based on Comprehensive and Real-time Usage Data (2018)

Smartphones and smartphone apps have undergone an explosive growth in the past decade. However, smartphone battery technology hasn't been able to keep pace with the rapid growth of the capacity and the functionality of smartphones and apps. As a result, battery has always been a bottleneck of a user's daily experience of smartphones. An accurate estimation of the remaining battery life could tremendously help the user to schedule their activities and use their smartphones more efficiently. Existing studies on battery life prediction have been primitive due to the lack of real-world smartphone usage data at scale. This paper presents a novel method that uses the state-of-the-art machine learning models for battery life prediction, based on comprehensive and real-time usage traces collected from smartphones. The proposed method is the first that identifies and addresses the severe data missing problem in this context, using a principled statistical metric called the concordance index. The method is evaluated using a dataset collected from 51 users for 21 months, which covers comprehensive and fine-grained smartphone usage traces including system status, sensor indicators, system events, and app status. We find that the remaining battery life of a smartphone can be accurately predicted based on how the user uses the device at the real-time, in the current session, and in history. The machine learning models successfully identify predictive features for battery life and their applicable scenarios.
Characterization of Sr-Doped LaCoO[sub 3]-YSZ Composites Prepared by Impregnation Methods (2004)

Porous yttria-stabilized zirconia (YSZ) was impregnated with aqueous solutions of the nitrate salts of Sr, La, and Co to obtain composites of (LSCo) and YSZ. X-ray diffraction showed that the perovskite phase formed after heating to 973 K and conductivities as high as 7 S/cm were achieved at 973 K with only 30 wt % LSCo. Coefficient of thermal expansion (CTE) measurements of the composites with as much as 50 wt % LSCo indicated that the CTEs were much lower than the weighted average of the YSZ and LSCo. Electrochemical measurements using symmetric cells in air indicated that the area-specific resistance (ASR) of the composites could be as low as 0.03 Ω cm2 at 973 K and 0.01 Ω cm2 at 1073 K. These low ASR were verified in a cell with an LSCo-YSZ cathode and a Co-ceria-YSZ anode, which exhibited a total electrode polarization loss of 0.25 Ω cm2 at 973 K and 0.1 Ω cm2 at 1073 K for operation in humidified However, changes in electrochemical performance with time showed that some electrode degradation occurred over a period of 250 h, even at 973 K. © 2004 The Electrochemical Society.

Composite Materials for X-ray Protection (1991)

We have developed and tested a radiation protection material that provides similar attenuation for diagnostic x-ray spectra to that of conventional Pb apron materials with approximately 30% reduced weight. By combining a number of elements with different K absorption energies, such as Ba, W, and Pb, energy attenuation for given spectra can be optimized with respect to total cross-sectional mass loading. Alternatively, garments with much higher protective factors at equivalent weight to conventional garments could be produced. The reduction in the amount of Pb used also reduces problems associated with the toxicity of the material during manufacture and disposal. Back strain can be reduced for personnel performing special radiological procedures that require wearing protective garments for long periods of time.
Impact of Ionic Liquid Physical Properties on Lipase Activity and Stability (2003)

Lipase activity and stability was investigated in dialkylimidazolium and pyrrolidinium-based ionic liquids with a variety of anions including hexafluorophosphate, acetate, nitrate, methanesulfonate, trifluoroacetate, and trifluoromethylsulfonate. The initial rate of lipase-catalyzed transesterification of methyl methacrylate in these ionic liquids and several organic solvents was examined as well as the polytransesterification of divinyl adipate and 1,4-butanediol. Free lipase (Candida rugosa) catalyzed the transesterification of methyl methacrylate in 1-butyl-3-methylimidazolium hexafluorophosphate at a rate 1.5 times greater than in hexane. However, no detectable activity was observed in all the "hydrophilic" ionic liquids studied. Methods of enzyme stabilization including adsorption, PEG-modification, and immobilization in polyurethane foam were ineffective in improving enzymatic activity in the hydrophilic ionic liquids. Polytransesterifications performed in 1-butyl-3-methylimidazolium hexafluorophosphate using Novozym 435 produced polyesters with weight average molecular weights limited to 2900 Da due to precipitation of the polymer. Solvatochromic studies and partition coefficient measurements suggest that ionic liquids are more polar and hydrophilic than organic solvents such as hexane, acetonitrile, and tetrahydrofuran. Stability studies indicate that lipases exhibit greater stability in ionic liquids than in organic solvents including hexane.
Evaluation of ceftriaxone, vancomycin and rifampicin alone and combined in an experimental model of meningitis caused by highly cephalosporin-resistant Streptococcus pneumoniae ATCC 51916 (2005)

Ceftriaxone plus vancomycin, and vancomycin plus rifampicin appeared to be effective in the therapy of experimental pneumococcal meningitis caused by highly cephalosporin-resistant strains such as ATCC 51916. Our results provide an experimental basis for using these combinations as empirical therapy for pneumococcal meningitis, regardless of the degree of cephalosporin resistance of the causative strain.
A Reconfigurable Multi-function DMA Controller for High-Performance Computing Systems (2018)

Huge bandwidth demand along with the requirement to synchronize data structures between different processing structures in multiprocessor system-on-chip (MPSoC) lead to the need to design dedicated memory access controllers. This paper presents the design of a reconfigurable multi-function memory direct memory controller (ReDMAC) for high-performance MPSoCs. The ReDMAC supports the capability of dynamic reconfiguration by enabling the hardware fabrics to be synthesized into various functions even if the system is working. The ReDMAC can support four operating modes, including direct memory access, matrix transposing, data sorting, and matrix merging. The ReDMAC has been modeled at the Register Transfer Level (RTL) using VHDL language. The controller has been simulated and evaluated on reconfigurability to work with individual functions. The controller is also synthesized with the Synopsys Design Compiler tool to compare hardware costs with the independent implementation of each individual function. Simulation and synthesis results indicate that the proposed design meets the required functionality, while the area of the controller decreases about three times compared to total area of independent function cores.
Electromyographic evaluation of cervical dystonia for planning of botulinum toxin therapy (2000)

The success of botulinum toxin (BT) injections for treatment of cervical dystonia depends on precise identification of dystonic muscles and on quantification of their dystonic involvement. Conventionally, this is attempted by clinical examination analysing the dystonic head position. In this presentation, a more systematic approach is sought by using an electromyography (EMG)-based evaluation procedure. In 10 consecutive patients with cervical dystonia not previously exposed to BT clinical examination, analysing the dystonic head position was performed to classify patients into four groups with similar dystonic head positions. Additionally, a 2-channel concentric needle EMG was used to measure the amplitudes of dystonic and maximal voluntary activities in sternocleidomastoid (SCM), splenius capitis (SC) and trapezius/semispinalis capitis (T/SS) muscles bilaterally. The ratio between both amplitudes, the dystonia ratio, was used to quantify dystonic muscle involvement. In all patients dystonia ratios could be calculated. In patients with similar head positions, EMG evaluation revealed different qualitative and quantitative dystonic involvement patterns. In six patients, there were discrepancies in identification of dystonic muscles between clinical examination and EMG evaluation. EMG evaluation excluded dystonic involvement in five patients. All excluded muscles were SCM. In one of these patients, additional T/SS involvement was detected by EMG evaluation. In one patient, SC involvement was revealed by EMG evaluation. All dystonic muscle involvement detected by EMG evaluation represented genuine dystonic muscle coactivation rather than compensatory muscle activity. The EMG evaluation presented allows quantitative and qualitative identification of dystonic muscle involvement which cannot be achieved by clinical examination. Both pieces of information may be helpful for optimization of BT therapy.

Privacy-Preserving Techniques and System for Streaming Databases (2012)

Streaming databases and other distributed, event-based systems are very useful tools for business and security applications. When event sources and event processing are distributed across multiple distinct domains, confidentiality and privacy issues emerge. These can be addressed by a number of cryptographic techniques. In this paper we consider high-performance symmetric encryption techniques. We build a system for privacy-preserving event correlation and evaluate the performance of the its techniques. We demonstrate efficient privacy-preserving event correlation using equality tests, greater-than comparisons and range queries. The results indicate that in comparable settings, it is therefore recommended to employ these techniques to address pertinent security and privacy concerns.
Effects of Rapamycin Treatment on Neurogenesis and Synaptic Reorganization in the Dentate Gyrus after Controlled Cortical Impact Injury in Mice (2015)

Post-traumatic epilepsy (PTE) is one consequence of traumatic brain injury (TBI). A prominent cell signaling pathway activated in animal models of both TBI and epilepsy is the mammalian target of rapamycin (mTOR). Inhibition of mTOR with rapamycin has shown promise as a potential modulator of epileptogenesis in several animal models of epilepsy, but cellular mechanisms linking mTOR expression and epileptogenesis are unclear. In this study, the role of mTOR in modifying functional hippocampal circuit reorganization after focal TBI induced by controlled cortical impact (CCI) was investigated. Rapamycin (3 or 10 mg/kg), an inhibitor of mTOR signaling, was administered by intraperitoneal injection beginning on the day of injury and continued daily until tissue collection. Relative to controls, rapamycin treatment reduced dentate granule cell area in the hemisphere ipsilateral to the injury two weeks post-injury. Brain injury resulted in a significant increase in doublecortin immunolabeling in the dentate gyrus ipsilateral to the injury, indicating increased neurogenesis shortly after TBI. Rapamycin treatment prevented the increase in doublecortin labeling, with no overall effect on Fluoro-Jade B staining in the ipsilateral hemisphere, suggesting that rapamycin treatment reduced posttraumatic neurogenesis but did not prevent cell loss after injury. At later times post-injury (8-13 weeks), evidence of mossy fiber sprouting and increased recurrent excitation of dentate granule cells was detected, which were attenuated by rapamycin treatment. Rapamycin treatment also diminished seizure prevalence relative to vehicle-treated controls after TBI. Collectively, these results support a role for adult neurogenesis in PTE development and suggest that suppression of epileptogenesis by mTOR inhibition includes effects on post-injury neurogenesis.
A model for fd phage penetration and assembly (1991)

Below 15 degrees C, chloroform causes fd phage to contract to I-forms, which are compact structures about 1/3 as long as the original phage. Above 15 degrees C, chloroform causes I-forms to contract to even more compact spheroidal S-forms. Here we show that the coat protein structure in I-forms is the same as the protein structure in the phage and the protein structure in S-forms is the same as the protein structure in bilayers. The conversions from fd----I-forms----S-forms are therefore suggested to mimic steps in fd penetration. The same conversions, in reverse order, are suggested to mimic steps in fd assembly.
Nucleolar protein P120 and its targeting for cancer chemotherapy. (1991)

Identification of the G1-P120 antigen with the aid of the monoclonal antibody to its "human-specific epitope" has resulted in rapid development of information on its molecular biology. With the monoclonal antibody, it rapidly became possible to identify and subsequently sequence its cDNA and with cDNA clones to isolate and sequence its genomic DNA. It was demonstrated that the protein had 4 major domains: a basic domain, an acidic domain, a hydrophobic and methionine-rich domain and a domain rich in cysteine and proline residues. In addition to a nuclear recognition signal, the epitope region is juxtaposed to phosphorylation sites. The epitope region contains the sequence Gln-Ala-Ala-Ala-Gly-Ile-Asn-Trp which is unique to the human P120 molecule; this may be a site for drug attack either by analogs to the region or by novel constructs based on antisense oligonucleotides. When tumor cells were transfected with antisense constructs of the P120 gene, growth rates were markedly reduced. 3T3 cells transformed by transfection with the P120 gene reverted to a nontransformed state by subsequent transfection and activation of a P120 antisense construct. Opportunities for control of malignant cells with antisense oligonucleotides are currently under study.
Managing shared access to a spectrum commons (2005)

The open access, unlicensed or spectrum commons approach to managing shared access to RF spectrum offers many attractive benefits, especially when implemented in conjunction with and as a complement to a regime of market-based, flexible use, tradable licensed spectrum ([Benkler02], [Lehr04], [Werbach03]). However, as a number of critics have pointed out, implementing the unlicensed model poses difficult challenges that have not been well-addressed yet by commons advocates ([Benjam03], [Faulhab05], [Goodman04], [Hazlett01]). A successful spectrum commons will not be unregulated, but it also needs not be command & control by another name. This paper seeks to address some of the implementation challenges associated with managing a spectrum commons. We focus on the minimal set of features that we believe a suitable management protocol, etiquette, or framework for a spectrum commons will need to incorporate. This includes: (1) No transmit only devices; (2) Power restrictions; (3) Common channel signaling; (4) Mechanism for handling congestion and allocating resources among users/uses in times of congestion; (5) Mechanism to support enforcement (e.g., established procedures to verify protocol is in conformance); (6) Mechanism to support reversibility of policy; and (7) Protection for privacy and security. We explain why each is necessary, examine their implications for current policy, and suggest ways in which they might be implemented. We present a framework that suggests a set of design principles for the protocols that will govern a successful commons management regime. Our design rules lead us to conclude that the appropriate Protocols for a Commons will need to be more liquid ([Reed05]) than in the past: (1) Market-based instead of C&C; (2) Decentralized/distributed; and, (3) Adaptive and flexible (Anonymous, distributed, decentralized, and locally responsive)
A Novel Approach To Produce Biologically Relevant Chemical Patterns at the Nanometer Scale:  Selective Molecular Assembly Patterning Combined with Colloidal Lithography (2002)

A novel patterning technique that combines colloidal patterning with selective adsorption of organic molecules has been used to chemically pattern metal oxide surfaces at length scales down to 50 nm. Lithographic nanofabrication using surface-assembled colloids as etch masks (“colloidal lithography”) was used to create nanopillars of TiO2 (50−90 nm in diameter, ∼20 nm in height) on whole oxidized silicon or quartz wafer substrates. These nanopillars were then rendered hydrophobic by the selective self-assembly of an organophosphate, whereas a poly(ethylene glycol)-grafted copolymer was adsorbed onto the surrounding SiO2 rendering it protein resistant. This resulted in a two-component chemical pattern, displaying contrast with respect to protein adsorption (protein-adhesive pillars on nonadsorbing background). This property allows for efficient translation of the lithographic pattern into a surface protein pattern by two simple dip-and-rinse processes in aqueous solutions. The feasibility of the method and its quality were tested by adsorbing fluorescently labeled streptavidin and biotinylated phospholipid vesicles. The sequential adsorption steps were monitored by fluorescence microscopy, atomic force microscopy, and scanning near-field optical microscopy. These techniques conclusively demonstrated the utility of the described approach for chemical patterning surfaces on the nanometer scale over large areas.
The effect of structural changes on dye diffusion in poly(ethylene terephthalate) (1968)

Abstract The diffusion of a disperse dye, 1‐amino‐4‐hydroxyanthraquinone (C.I. Disperse Red 15) into poly(ethylene terephthalate) fibers has been studied as a function of heatsetting temperature and draw ratio. It was found that the dynamic loss modulus E ″, measured under the dyeing conditions, was related to the dye diffusivity D . This indicates that the diffusion is controlled by the mobility of the polymer chain segments. Both the diffusivity and dye saturation values do not vary monotonically with heatsetting temperature but exhibit a minimum at a heat‐setting temperature near 175°C. X‐ray diffraction measurements were used to show that this behavior is attributable to crystallinity and crystal size changes resulting from heat‐setting.
A Low Modulus, High Fatigue Life Elastomer Compound for Suspension Applications (1981)

Abstract Soft elastomeric suspension bushing compounds have been developed which are based on natural rubber/polybutadiene (NR/BR) blends which have been softened with polyisobutylene (IM). The new compounds have a Shore A hardness of 45 and a fatigue life of 97 kc and 80 kc for the urethane cured and semi-EV cured compounds respectively. This compares with a fatigue life of 62 kc for the current production compound (Shore A 65). It appears that the mechanical behavior, i.e. resistance to crack growth, of natural rubber based compounds is unaffected by the addition of IM. Fatigue life, compression set and retention of physical properties after heat aging of the new compounds are also superior to the production compound. The dynamic mechanical properties of the new compounds were evaluated and found to have a slightly greater temperature sensitivity than the production compounds.
Comprehensive Approach to Structural and Functional Glycomics Based on Chemoselective Glycoblotting and Sequential Tag Conversion (2008)

Changes in protein glycosylation profoundly affect protein function. To understand these effects of altered protein glycosylation, we urgently need high-throughput technologies to analyze glycan expression and glycan-protein interactions. Methods are not available for amplification of glycans; therefore, highly efficient sample preparation is a major issue. Here we present a novel strategy that allows flexible and sequential incorporation of various functional tags into oligosaccharides derived from biological samples in a practical manner. When combined with a chemoselective glycoblotting platform, our analysis enables us to complete sample preparation (from serum to released, purified, methyl-esterified, and labeled glycans) in 8 h from multiple serum samples (up to 96 samples) using a 96-well microplate format and a standard de-N-glycosylation protocol that requires reductive alkylation and tryptic digestion prior to PNGase F digestion to ensure maximal de-N-glycosylation efficiency. Using this technique, we quantitatively detected more than 120 glycans on human carcinoembryonic antigens for the first time. This approach was further developed to include a streamlined method of purification, chromatographic fractionation, and immobilization onto a solid support for interaction analysis. Since our approach enables rapid, flexible, and highly efficient tag conversion, it will contribute greatly to a variety of glycomic studies.
A study on corrugated diaphragms for high-sensitivity structures (1997)

In this paper, the corrugated diaphragm technique is studied for applications to micromachined highly sensitive devices. Both static and dynamic behaviours of square corrugated diaphragms with various structural parameters and material properties are analysed using the finite-element method (FEM). The simulations show that very high performance (e.g., high mechanical sensitivity, small static deflection and high resonance frequency) of the diaphragms can be achieved using this technique. For the proposed corrugated diaphragms with anisotropically etched corrugations, much better reproducibility of the device performance can be expected. Different types of square diaphragm with rectangular corrugations have been fabricated using the silicon anisotropic etching technique and the optimized processes are presented. The measurements have shown reasonable agreement with the analyses. A capacitive pressure sensor is realized by the corrugation technique, with which sensitivity as high as 0.33% has been achieved.
Effect of carbon dioxide on growth of Pseudomonas fluorescens (1979)

In minimal medium at 30 degrees C, growth of Pseudomonas fluorescens was stimulated when the pressure (p) of CO2 in solution was 100 mm of Hg, but at higher concentrations the growth rate declined linearly with increasing pCO2. All concentrations of CO2 were inhibitory for growth in complex medium, and at 30 degrees C the maximum degree of inhibition was attained when pCO2 was 250 mm of Hg. The degree of inhibition at a constant pCO2 in solution increased with decreasing temperature. The degree of inhibition was directly proportional to temperature for growth in complex medium, but not in minimal medium. The inhibition of cell respiration by CO2 was the same whether cells had been grown in air or in the presence of CO2, indicating that adaptive enzyme synthesis does not occur in response to CO2.
