Exploiting Explicit and Implicit Feedback for Personalized Ranking (2016)

The problem of the previous researches on personalized ranking is that they focused on either explicit feedback data or implicit feedback data rather than making full use of the information in the dataset. Until now, nobody has studied personalized ranking algorithm by exploiting both explicit and implicit feedback. In order to overcome the defects of prior researches, a new personalized ranking algorithm (MERR_SVD++) based on the newest xCLiMF model and SVD++ algorithm was proposed, which exploited both explicit and implicit feedback simultaneously and optimized the well-known evaluation metric Expected Reciprocal Rank (ERR). Experimental results on practical datasets showed that our proposed algorithm outperformed existing personalized ranking algorithms over different evaluation metrics and that the running time of MERR_SVD++ showed a linear correlation with the number of rating. Because of its high precision and the good expansibility, MERR_SVD++ is suitable for processing big data and has wide application prospect in the field of internet information recommendation.
Group $K$-Means. (2015)

We study how to learn multiple dictionaries from a dataset, and approximate any data point by the sum of the codewords each chosen from the corresponding dictionary. Although theoretically low approximation errors can be achieved by the global solution, an effective solution has not been well studied in practice. To solve the problem, we propose a simple yet effective algorithm \textit{Group $K$-Means}. Specifically, we take each dictionary, or any two selected dictionaries, as a group of $K$-means cluster centers, and then deal with the approximation issue by minimizing the approximation errors. Besides, we propose a hierarchical initialization for such a non-convex problem. Experimental results well validate the effectiveness of the approach.
Endoscopic Treatment of Subglottic and Tracheal Stenosis by Radial Laser Incision and Dilation (1987)

Five patients with severe fibrous subglottic and tracheal stenosis were treated by endoscopic radial laser incision and dilation using both carbon dioxide and neodymium:yttrium aluminum garnet lasers. Good results were noted without complications in all patients in a follow-up period of at least 1 year. Careful selection of patients, excluding those with tracheal collapse or tracheomalacia, and preservation of tracheal epithelium with minimal heat and mechanical trauma are considered essential for good results.
Motivational Incentives for developing salesforce performance in emerging markets (2011)

Motivation is important because it determines and individual's effort toward performing a task and it leads to an optimistic and challenging attitude at work place. Incentive motivation is concerned with the way goals influence behavior. Incentive is the promise or stimulus for greater action. Incentives are something that is given in addition to wages. It means additional remuneration or benefit to an employee in recognition of achievement or better work. Organizations in emerging markets are more likely to give group rewards and generally do not encourage risk taking as much as developed economies. Money motivates employees to some extent but there are other powerful sources of motivation such as interesting and challenging tasks and assignments, praise, good interpersonal relations etc. This paper analyzes incentives plan structure of sales people in Croatia. Advantages and disadvantages of different compensation plans and benefits for salespeople are discussed.
Cinnamon water extracts increase glucose uptake but inhibit adiponectin secretion in 3T3-L1 adipose cells (2006)

The effects of three concentrations (0.2, 0.3, and 0.4 mg/mL) of a cinnamon extract (CE) (Cinnamomum zeylanicum) on glucose uptake and adiponectin secretion in 3T3-L1 adipocytes were examined in the presence and absence of 0.5 nM and 50 nM insulin. In the absence of insulin, adipocytes exposed to 0.2 mg/mL CE showed an approximate two-fold increase in glucose uptake relative to controls although glucose uptake was unaffected by the two higher concentrations of CE. No effect of CE on glucose uptake was noted in the presence of 0.5 nM insulin whereas the two highest concentrations (0.3 and 0.4 mg/mL) of CE showed a significant dose-dependent decrease in glucose uptake in the presence of 50 nM insulin. Treatment of the adipocytes with 50 nM wortmannin, an irreversible inhibitor of the p110 isoform of phosphoinositide 3'-kinase, was associated with complete inhibition of the stimulated glucose uptake induced by 0.2 mg/mL CE. Treatment of the adipocytes with 0.2 mg/mL CE was associated with an inhibition of adiponectin secretion to levels that were nondetectable. The present study indicates that although 0.2 mg/mL CE has insulin-mimetic action in 3T3-adipocytes in terms of glucose uptake, secretion of the antidiabetic hormone adiponectin is adversely affected.
Effect of Pullulanase and α‐Amylase on Hydrolysis of Waxy Corn Starch (1990)

Abstract Using commercial pullulanase, α‐amylase and their mixture, partial hydrolysis of waxy corn starch was characterised for optimising production of maltodextrins free of D‐glucose. Compared to pullulanase or α‐amylase alone, the mixture of these two (simultaneous or successive addition) on the substrate enhanced the efficiency of maltodextrin turnover with low or traces of D‐glucose production in a short time. D‐glucose was removed from dextrins by membrane filtration and the yield of dextrin above DP6 was 60–65%.
Defibrination after Brain-Tissue Destruction (1974)

Abstract A prospective study was conducted to evaluate defibrination after acute head trauma. Defibrination was not observed in 13 patients In whom trauma apparently did not destroy brain tissue. In contrast, evidence of defibrination — hypofibrinogenemia, elevated levels of serum fibrinogen-related or fibrin-related antigen and low levels of factors V, VIII or platelets — was found in nine of 13 patients in whom brain-tissue destruction was established by direct inspection. All nine patients had a strongly positive protamine test, suggesting that intravascular coagulation had occurred. Since test results returned toward normal within hours, the active phase of defibrination apparently was brief. Nevertheless, hemostatic abnormalities were severe enough to have affected the neurologic consequences of intracranial bleeding. Clinical findings attributable to fibrin in the microcirculation (e.g., microangiopathic hemolytic anemia or renal failure) were not encountered. The potentially salvageable patient wit...
Coherent homodyne detection using time-gated amplification and LiNbO3 optical 90° hybrid (2004)

We investigated coherent detection of BPSK signal using LiNbO3 optical 90o hybrid with pulsed and CW local-oscillator. Bit-error-rate improvement was observed using pulsed local-oscillator and it provides pulse shaping capability that reduces pulse broadening penalty.
Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction (2019)

Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of sensitivity, speed, operating temperature, and spectral range. Here, we use graphene as a photoactive material to overcome all of these limitations in one device. We introduce a novel detector for terahertz radiation that exploits the photothermoelectric (PTE) effect, based on a design that employs a dual-gated, dipolar antenna with a gap of ∼100 nm. This narrow-gap antenna simultaneously creates a pn junction in a graphene channel located above the antenna and strongly concentrates the incoming radiation at this pn junction, where the photoresponse is created. We demonstrate that this novel detector has an excellent sensitivity, with a noise-equivalent power of 80 pW/[Formula: see text] at room temperature, a response time below 30 ns (setup-limited), a high dynamic range (linear power dependence over more than 3 orders of magnitude) and broadband operation (measured range 1.8-4.2 THz, antenna-limited), which fulfills a combination that is currently missing in the state-of-the-art detectors. Importantly, on the basis of the agreement we obtained between experiment, analytical model, and numerical simulations, we have reached a solid understanding of how the PTE effect gives rise to a THz-induced photoresponse, which is very valuable for further detector optimization.

Electrodeposition modeling and optimization to improve thin film patterning with orchestrated structure evolution (2012)

Orchestrated structure evolution is an alternative nanomanufacturing approach that combines the advantages of top-down patterning and bottom-up self-organizing growth. It relies upon tool-directed patterning to create 'seed' locations on a surface from which a subsequent deposition process produces the final, merged film. Despite its demonstrated ability to reduce patterning time by orders of magnitude, our prior reliance on mass transfer limited deposition and square seed arrays resulted in extraneous film growth along pattern edges, thereby limiting the pattern quality of the final film. Here, quality improvements are demonstrated by modeling and tuning the growth mechanism of the deposition step to include charge transfer effects. In addition, a seed positioning optimization technique derived from simulated annealing is introduced as a method for relocating the seeds to minimize film overgrowth at the pattern edges. These improvements enable OSE to maintain geometric quality while substantially reducing the time and cost compared to traditional direct-write manufacturing methods.
Displacement response, detection limit, and dynamic range of fiber-optic lever sensors (1991)

The authors present the evaluation of the displacement response, detection limit, and dynamic range of fiber-optic lever sensors in a general format to establish their dependence on fiber sizes, optoelectronic detector specifications, input power, and other relevant parameters. The formations for the normalized reflected optical power change are derived for the evaluation of the optimal sensor response, the linearity range, and the minimum detectable displacement. The theoretical models are verified by an experiment which determines sensor response, modulation index, reflected optical power change, and linear response range through dynamic measurement. The application of this theoretical model to the study of a fiber-optic microphone for acoustic pressure detection is considered.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis and properties of defined DNA oligomers containing base mispairs involving 2-aminopurine (1986)

DNA heptamers containing the mutagenic base analogue 2-aminopurine (AP) have been chemically synthesized and physically characterized. We report on the relative stabilities of base pairs between AP and each of the common DNA bases, as determined from heptamer duplex melts at 275 and 330 nm. Base pairs are ranked in order of decreasing stability: AP.T greater than AP.A greater than AP.C greater than AP.G. It is of interest that AP.A is more stable than AP.C even though DNA polymerase strongly favors the formation of AP.C over AP.A base pairs. Comparisons of melting profiles at 330 nm and 275 nm indicate that AP.T, AP.A, and AP.C base pairs are annealed in heptamer duplexes and melt 2-3 degrees prior to surrounding base pairs, whereas AP.G appears not to be annealed.
Amphiphilic Cylindrical Core−Shell Brushes via a “Grafting From” Process Using ATRP (2001)

Atom transfer radical polymerization (ATRP) was applied to the synthesis of amphiphilic cylindrical polymer brushes by using the “grafting from” technique. The procedure included the following steps: (1) ATRP of 2-hydroxyethyl methacrylate (HEMA) gave well-defined poly(HEMA), (2) subsequent esterification of the pendant hydroxy groups of poly(HEMA) with 2-bromoisobutyryl bromide yielded a polyinitiator, poly(2-(2-bromoisobutyryloxy)ethyl methacrylate (PBIEM), (3) ATRP of various monomers (tert-butyl acrylate, or styrene) using PBIEM as polyinitiator yielded cylindrical brushes with homopolymer side chains, (4) addition of a second monomer (styrene or tert-butyl acrylate) formed the cylindrical brushes with diblock copolymer side chains (core−shell cylinders), and (5) hydrolysis of the poly(tert-butyl acrylate) (PtBA) block of the side chains to poly(acrylic acid) (PAA) formed amphiphilic core−shell polymer brushes. By using this technique, well-defined core−shell cylindrical polymer brushes with polystyrene (PS), PtBA, PS-b-PtBA, PtBA-b-PS, PS-b-PAA, or PAA-b-PS as side chains were successfully synthesized. The molecular weights and radii of gyration of the polymer brushes were obtained by static light scattering in THF. The absence of inter/intra-macromolecular coupling reactions during ATRP synthesis was confirmed by GPC, NMR, and MALDI−TOF analyses of the side chains and scanning force microscopy (SFM). Single wormlike unimolecular nanocylinders are clearly visualized on a mica surface while aggregates are usually observed on a SiOx surface. The brushes with PS-b-PtBA side chains were hydrolyzed to PS-b-PAA side chains forming unimolecular wormlike micelles. These unimolecular micelles showed a unique response to solvent quality, as indicated by 1H NMR and dynamic light scattering.
Topical Anti-Inflammatory Activity of Human Recombinant Epidermal Growth Factor (1999)

The topical anti-inflammatory activity of epidermal growth factor (EGF) was evaluated in inflammation models induced by 12-Otetradecanoylphorbol-13-acetate, croton oil and arachidonic acid. When EGF (1.5, 3 or 6 microg/ear) was coapplied with each inflammatory agent, there was a dose-related decrease in inflammation as assessed by ear punch weights, myeloperoxidase activity as well as by histopathological studies. The precise anti-inflammatory action of EGF is yet unclear, but we believe that interference with arachidonic acid metabolism may play an important role.
Enhancing light extraction in organic light-emitting devices via hemispherical microlens arrays fabricated by soft lithography (2011)

We demonstrate enhanced light extraction in organic light-emitting devices (OLEDs) by using microlens arrays fabricated by a soft lithography technique. A large-area and close-packed polystyrene (PS) monolayer was formed on the SiO2 substrate using a convective-capillary assembly method, and a polydimethylsiloxane polymer was used to obtain a concave template, from which microlens arrays were fabricated from a photopolymerizable transparent optical adhesive. The microlens contact angle and array fill factor both depend on the size of PS microspheres, and nearly close-packed, hemispherical microlens arrays with microlens contact angle of (85 ± 5 deg) and array fill factor of (85 ± 3)% were obtained with 100-μm PS microspheres. The enhancement in the light-extraction efficiency in OLEDs when such fabricated microlens arrays were attached to the light-emitting surface depends on the contact angle of microlens, device size, and detailed multilayer structure of the OLED. For a large-area (12 × 12 mm) fluorescent OLED with a near close-packed hemispherical microlens array, a maximum enhancement of (70 ± 7)% in the light-extraction efficiency was achieved.
Needle Trap Device (NTD)를 위한 열탈착 장치의 제작과 특성 평가 (2015)

주사기형 소형 흡착 장치 (needle trap device, NTD)를 위한 열탈착 장치를 제작하고 특성을 평가하였다. 소형 카트리지형 히터와 온도 센서 및 온도조절장치를 사용하여 제작된 NTD용 열탈착 장치는 비교적 짧은 warm-up 시간 (10분 이하)를 필요로 하며, 온도 fluctuation 없이 매우 안정적으로 사용될 수 있음을 확인하였다. 이 장치를 이용하여 Dimethyl methylphosphonate(DMMP)의 carry-over 시험을 통해 적정 흡착 온도 (250 ℃)를 확인할 수 있었다.
Mycoplasma genitalium, a New Species from the Human Urogenital Tract (1983)

Two mycoplasmas recovered from human urogenital tracts were similar in their biochemical and serological properties. These organisms possessed a unique terminal structure that appeared to be associated with attachment to tissue cells and erythrocytes. The organisms fermented glucose but did not hydrolyze urea or arginine. Growth occurred at 30 to 37°. Cholesterol was required for growth. Unlike most other mycoplasmas, both strains were susceptible to thallium acetate. These two organisms were serologically distinct from other Mycoplasma species and from a group of unclassified serotypes of mycoplasmas. On the basis of these findings and other morphological, biological, and serological properties of the microorganisms, we propose that mycoplasmas with these characteristics belong to a new species, Mycoplasma genitalium. Strain G-37 (= ATCC 33530) is the type strain.
Managed-Pressure Drilling (MPD) Field Trials Demonstrate Technology Value (2006)

Abstract Is this the beginning of the end of weighted mud systems? An advanced well control practice called Managed Pressure Drilling (MPD) is staged to challenge the conventional drilling practice of when in doubt "weight it up". Formation overpressures have traditionally forced operators to weight-up mud systems in order to advance drilling operations while preventing formation fluids invasion. A direct consequence of increased mud weight is a dramatic reduction in drilling Rate of Penetration (ROP), requirement for additional casing seats/strings and increased well control risks due to kicks from losses. This drilling hazard has represented a major source of invisible or intangible lost time and hence, cost. A drilling hazard mitigation multi-well trial was carried out to investigate and quantify the reduction in ROP as a result of mud weight increases to overcome troublesome formation overpressures and associated High Pressure Low Volume (HPLV) nuisance gas. Without increasing mud weight to control overpressures, MPD technology was applied to safely and cost effectively drill through overpressures and avoid an intermediate casing string normally used to isolate a loss zone. MPD trial results examined in this paper addresses many of the issues and provides forward-looking statements regarding large-scale introduction of the system to other fields. The multi-well trial results showed a close match to the predicted MPD ROP curve, achieving an economically rewarding ROP gain of at least 2.5 times and gross well cost reductions of over 20%, without recordable troublesome zone Non-Productive Time (NPT). Initial concerns of borehole instabilities using lightweight mud with borehole pressures less than the adjacent pore pressure were not observed (in both vertical and directional well cases).
Comprehensive Study and Modeling of Acetic Acid Effect on <i>Trichoderma reesei</i> Growth (2013)

Acetic acid is one of the major potential inhibitors of cellular growth resulting from acid pretreatment of lignocellulosic biomass. To use lignocellulose hydrolysate in biorefineries it is necessary to assess their effect on the microorganisms likely to be used. An attractive option is to use a part of these hydrolysates for on-site cellulase production. Based on an industrial process that included a fast initial growth phase, the effect on Trichoderma reesei grown on glucose was assessed and modeled at different concentrations and pH. Acetic acid had a strong effect on T. reesei growth rate and yield, which correlated only with the concentration of the undissociated form in solution. The specific growth rate was accurately modeled by two different classic inhibition models as a function of pH and total acetic acid concentration. Co-consumption of glucose and acetic acid was observed, so that the culture medium was gradually detoxified by the cells. With or without glucose, acetic acid was mineralized into carbon dioxide at a similar specific rate, but no growth was observed without glucose. A 2.5-fold increase in the maintenance coefficient was observed, due to the need for glucose consumption to preserve cell integrity, which corresponded to a one-third decrease in the overall biomass yield. The resulting models can be used to simulate T. reesei growth on acetic acid-containing media and to choose the optimum pH for efficient growth on lignocellulosic biomass hydrolysates.
The <i>Xenopus</i> protein kinase pEg2 associates with the centrosome in a cell cycle-dependent manner, binds to the spindle microtubules and is involved in bipolar mitotic spindle assembly (1998)

By differential screening of a Xenopus laevis egg cDNA library, we have isolated a 2,111 bp cDNA which corresponds to a maternal mRNA specifically deadenylated after fertilisation. This cDNA, called Eg2, encodes a 407 amino acid protein kinase. The pEg2 sequence shows significant identity with members of a new protein kinase sub-family which includes Aurora from Drosophila and Ipl1 (increase in ploidy-1) from budding yeast, enzymes involved in centrosome migration and chromosome segregation, respectively. A single 46 kDa polypeptide, which corresponds to the deduced molecular mass of pEg2, is immunodetected in Xenopus oocyte and egg extracts, as well as in lysates of Xenopus XL2 cultured cells. In XL2 cells, pEg2 is immunodetected only in S, G2 and M phases of the cell cycle, where it always localises to the centrosomal region of the cell. In addition, pEg2 'invades' the microtubules at the poles of the mitotic spindle in metaphase and anaphase. Immunoelectron microscopy experiments show that pEg2 is located precisely around the pericentriolar material in prophase and on the spindle microtubules in anaphase. We also demonstrate that pEg2 binds directly to taxol stabilised microtubules in vitro. In addition, we show that the presence of microtubules during mitosis is not necessary for an association between pEg2 and the centrosome. Finally we show that a catalytically inactive pEg2 kinase stops the assembly of bipolar mitotic spindles in Xenopus egg extracts.
Personal Identification Utilizing Finger Surface Features (2005)

In this paper we present a novel approach for personal identification, which utilizes finger surface features as a biometric identifier. Using dense range data images of the hand, we calculate the curvature-based surface representation, shape index, for the index, middle, and ring fingers. This representation is used for comparisons to determine subject similarity. Our experiments involve the use of a large data set of range images collected over time. We examine the performance of individual finger surfaces as a biometric identifier as well as the performance when using the three finger surfaces in conjunction. The results of our experiments are presented, which indicate that this approach performs well for a first-of-its-kind biometric technique.
