What's Most Important to Customer Satisfaction: Service Recovery (1997)

Customer professionals generally agree that complaint or problem resolution is a key to maintaining client loyalty. Unresolved problems have a particularly negative impact on both continued product use and word-of-mouth recommendations to others. Dissatisfied customers tell far more people about their experience than do routinely satisfied customers. The bank's response to customer problems can be critical importance. Data from Technical Assistance Research Programs (TARP) finds that the majority (63%) customers who do take the time to complain are not completely satisfied with the bank's response to their problem. Various studies indicate that adequate problem/complaint resolution -- or service recovery -- leads to increased (not merely retained) customer loyalty. Newly satisfied customers are turned into active advocates for the business. The importance problem resolution to customer satisfaction was confirmed in a recent study one bank's retail banking clients. As part an ongoing improvement program, a $2 billion-assets locally owned Midwest bank joined with our firm to develop and test satisfaction surveys for both retail and commercial customers. Surveys were mailed to a randomly selected sample 1,620 customers who used the bank for at least three services (checking, savings, ATM). Many these customers also had loans from the bank. A three-wave mailing resulted in 973 usable responses. For the purposes this report, we are focusing on correlations between the questionnaire items and overall score, rather than on satisfaction scores themselves. Banks differ from one another in performance quality and scores will thus vary considerably from bank to bank. On the other hand, issues most to customers should be fairly consistent across institutions. Issues of most concern can be defined as those questionnaire items most highly correlated with overall satisfaction. In our work in the health-care field, we find that correlations between survey items and overall satisfaction score are remarkably similar across institutions. In other words, although hospital quality and individual patient experiences may vary significantly, what's important to patients does not vary much from provider to provider. Pending additional research, we assume the same holds for bank customers. We feel confident that results from this study a single bank can be generalized to other financial institutions. The accompanying table shows the correlations we found at the bank. The ordering items yields several surprises. Accuracy -- a characteristic stressed frequently in our bank customer focus groups -- is fairly high on the list, yet falls well below other elements in its relation to overall satisfaction with the bank. Customer experiences that typically yield the most vocal complaints -- waiting time, convenience banking hours, and even teller courtesy -- are least correlated with overall satisfaction. …
Impairing Factors in Remote-PPG Pulse Transit Time Measurements on the Face (2018)

The time it takes for a pulse wave to propagate between two arterial sites-i.e., the pulse transit time (PTT)- has received considerable attention as a marker of aortic stiffness and as a surrogate for blood pressure. However, obtrusiveness and manual intervention requirements render conventional PTT measurement methods inappropriate for ubiquitous monitoring. In this regard, high-speed camera systems are interesting alternatives. Recognizably, a technical breakthrough would be estimating PTT with a relatively inexpensive RGB camera pointed at the face only. A simple means to do this is determining the phase shift (PS) between photoplethysmographic (PPG) signals extracted at collocated skin pixels. In this paper, we show that the validity of this approach is threatened by skin variability. We analysed simultaneous video recordings of the neck and face in 21 subjects (ages, 33 ± 11 yrs). These were used to extract PPG signals at the face and skin motion (sMOT) signals at the vicinity of the carotid artery. Using sMOT as reference signal, we show that the pressure wave undergoes delay and frequency leakage as it propagates across the arterial tree; the extent of propagation distortion is subject-dependent and place PPG-based estimations at a disadvantage in comparison with PTTs measured at the arterial level. Awareness is further raised for the site-dependency of PS outcomes by the provision of facial PPG-phase maps and collocated PPG signals. Lastly, impairments due to waveform dissimilarity are demonstrated under exercise-induced PTT changes. In conclusion, PS is unsuitable for PTT measurements at the face.
Ruthenium-catalysed cross metathesis binding of functionalized olefins to polystyrene resin via a novel allylsilyl linker suitable for electrophilic cleavage (1997)

1% Divinylbenzene-crosslinked allyldimethylsilyl polystyrene 1 undergoes highly efficient ruthenium-catalysed cross-metathesis with functionalized terminal olefins and allows electrophilic cleavage of the resulting functionalized allylsilane.
The influence of disorder on the space charge field formation in photorefractive polymers (1996)

Recent holographic time-of-flight experiments in photorefractive polymers have shown the space charge field to depart from its expected behaviour. We show that this discrepancy arises due to the influence of disorder on the charge transport process.
Composition-dependent structural transition in epitaxial <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:msub><mml:mi>Bi</mml:mi><mml:mrow><mml:mn>1</mml:mn><mml:mo>−</mml:mo><mml:mi>x</mml:mi></mml:mrow></mml:msub><mml:msub><mml:mi>Sb</mml:mi><mml:mi>x</mml:mi></mml:msub></mml:mrow></mml:math> thin films on Si(111) (2019)

Bismuth-antimony alloys (${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}$) are topological insulators between 7 and 22% Sb in bulk crystals, with an unusually high conductivity suitable for spin-orbit torque applications. Reducing the thickness of epitaxial ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}$ films is expected to increase the maximum band gap through quantum confinement, which may improve isolation of topological surface-state transport. Like Bi(001) on Si(111), ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}$ has been predicted to form a black phosphoruslike allotrope with unique electronic properties in nanoscale films; however, the impact of Sb alloying on both the bulklike and nanoscale crystal structures on Si(111) is currently unknown. Here we demonstrate that the allotropic transition in ultrathin epitaxial ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}$ films on Si(111) is suppressed above 8--9% Sb, resulting in an unexpected (012) orientation within the topologically insulating regime. The metallic temperature-dependent conductivity associated with surface states in Bi(001) was not observed in the ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}(012)$ films, suggesting that the (012) orientation may significantly reduce surface-state transport. Growth on a Bi(001) buffer layer may prevent this orientation transition. Finally, we demonstrate that Sb alloying improves the continuity and quality of nanoscale ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}(012)$ films in the thickness regime expected for the black phosphorus allotrope, suggesting a promising route to large-area growth of puckered-layer two-dimensional ${\mathrm{Bi}}_{1\ensuremath{-}x}{\mathrm{Sb}}_{x}$, which will be necessary to harness its unique electronic properties in practical applications.
CONTROL OF MENSTRUAL DISTURBANCES AND HYPO-OVARIAN STERILITY; NINE YEARS OF EXPERIENCE WITH EQUINE GONADOTROPIN (1947)

(This is a large series of cases and the results reported certainly compare very favorabl with those of the many other plans which are constantly being recommended for the various menstrual disturbances. The sequence of estrogen-progesterone followed by the equii gonadotrophic hormone is as nearly rational as one can expect in the present state of our knowledge. One cannot help wondering, however, why the same treatment cures so man disorders in which the pathologic physiologic disturbance is so different.–Ed.)
Cancer Detection and Therapy. Affinity of Neoplastic, Embryonic, and Traumatized Tissues for Porphyrins and Metalloporphyrins. (1948)

Summary and ConclusionsThese experiments show that all porphyrins tested accumulate in neoplastic (induced and transplanted sarcomas, spontaneous and transplanted mammary carcinomas), embryonic and regenerating tissues. Introduction of a metal (zinc) into the porphyrin molecule did not destroy the tendency of the porphyrin to concentrate in tumors. The tendency of injected porphyrins and metalloporphyrins to accumulate in lymph nodes may limit the therapeutic usefulness of these compounds in all neoplastic diseases except lymphatic leukemias. The possibility of using small doses of radioactive metalloporphyrins for detecting deep cancer is being investigated.
Role of Hcp, a type 6 secretion system effector, of Aeromonas hydrophila in modulating activation of host immune cells (2010)

Recently, we reported that the type 6 secretion system (T6SS) of Aeromonas hydrophila SSU plays an important role in bacterial virulence in a mouse model, and immunization of animals with the T6SS effector haemolysin co-regulated protein (Hcp) protected them against lethal infections with wild-type bacteria. Additionally, we showed that the mutant bacteria deleted for the vasH gene within the T6SS gene cluster did not express the hcp gene, while the vasK mutant could express and translocate Hcp, but was unable to secrete it into the extracellular milieu. Both of these A. hydrophila SSU mutants were readily phagocytosed by murine macrophages, pointing to the possible role of the secreted form of Hcp in the evasion of the host innate immunity. By using the ΔvasH mutant of A. hydrophila, our in vitro data showed that the addition of exogenous recombinant Hcp (rHcp) reduced bacterial uptake by macrophages. These results were substantiated by increased bacterial virulence when rHcp was added along with the ΔvasH mutant in a septicaemic mouse model of infection. Analysis of the cytokine profiling in the intraperitoneal lavage as well as activation of host cells after 4 h of infection with the ΔvasH mutant supplemented with rHcp indicated that this T6SS effector inhibited production of pro-inflammatory cytokines and induced immunosuppressive cytokines, such as interleukin-10 and transforming growth factor-β, which could circumvent macrophage activation and maturation. This mechanism of innate immune evasion by Hcp possibly inhibited the recruitment of cellular immune components, which allowed bacterial multiplication and dissemination in animals, thereby leading to their mortality.
Investigation of antimicrobial peptide salts: Efficacy and solubility in surfactant solutions for latex systems (2006)

The study and application of antimicrobial peptides is a growing niche field in the areas of pharmaceutics and medicinal chemistry. As a result, the majority of testing and development is completed underin vitro conditions. The use of synthetically derived antimicrobial peptides in applications outside the medical realm is a relatively untapped field, with the significance of interactions between antimicrobial oligopeptides and the ingredients of polymer systems being largely unknown. Water-based polymer coatings systems are attractive targets for microbial invasion because of their inherent material properties. Water-based polymer latex coatings contain a number of components which aide in stabilization and coalescence of the polymer particles, such as surfactants and polymeric cellulose-derived molecules, with several types of molecular structures existing for each. Microbes are able to flourish within the water phase of the latexes while taking sustenance from these dispersion components, resulting in a loss of properties commonly known as ‘spoilage’. This work addresses the impact of formulation variables, specifically surfactant structure, on the solution and antimicrobial behavior of a model antimicrobial oligopeptides through the use of HT absorbance measurements.
Automation of tissue piercing using circular needles and vision guidance for computer aided laparoscopic surgery (2010)

Despite the fact that minimally invasive robotic surgery provides many advantages for patients, such as reduced tissue trauma and shorter hospitalization, complex tasks (e.g. tissue piercing or knot-tying) are still time-consuming, error-prone and lead to quicker fatigue of the surgeon. Automating these recurrent tasks could greatly reduce total surgery time for patients and disburden the surgeon while he can focus on higher level challenges. This work tackles the problem of autonomous tissue piercing in robot-assisted laparoscopic surgery with a circular needle and general purpose surgical instruments. To command the instruments to an incision point, the surgeon utilizes a laser pointer to indicate the stitching area. A precise positioning of the needle is obtained by means of a switching visual servoing approach and the subsequent stitch is performed in a circular motion.
Surface Studies on SiC as Related to Contacts (1997)

We review the current status of surface studies on SiC as related to development of metal–semiconductor contacts, focusing on ten selected aspects of work through 1996. The ten areas include high resolution microscopy, XPS core-level binding energies versus temperature, surface graphitization, plasmon-loss features, work function and electron affinity, sputtering, etching, surface preparation and cleaning, surface states, and the index of interface behavior for SiC. Special consideration is given to the Ni/SiC ohmic contact system, and we discuss possible future directions in SiC contact surface research.
PURIFICATION OF HYDROCHLORIC ACID BY ISOOCTANE EXTRACTION (1993)

ABSTRACT Removal of organic compounds from hydrocloric acid can be performed by a solvent extraction process followed by a solvent regeneration step by adsorption with sepiolite. The extraction study includes the analysis of the influence of the operating conditions, the determination of the solute distribution coefficient for isooctane and the effect of temperature on the extraction. The adsorption isotherms were calculated to check the technical viability of the method. The obtained efficiency of extraction is close to 90 wt%, whereas that of the solvent regeneration recovery is over 67 wt%
New features and insights for pedestrian detection (2010)

Despite impressive progress in people detection the performance on challenging datasets like Caltech Pedestrians or TUD-Brussels is still unsatisfactory. In this work we show that motion features derived from optic flow yield substantial improvements on image sequences, if implemented correctly - even in the case of low-quality video and consequently degraded flow fields. Furthermore, we introduce a new feature, self-similarity on color channels, which consistently improves detection performance both for static images and for video sequences, across different datasets. In combination with HOG, these two features outperform the state-of-the-art by up to 20%. Finally, we report two insights concerning detector evaluations, which apply to classifier-based object detection in general. First, we show that a commonly under-estimated detail of training, the number of bootstrapping rounds, has a drastic influence on the relative (and absolute) performance of different feature/classifier combinations. Second, we discuss important intricacies of detector evaluation and show that current benchmarking protocols lack crucial details, which can distort evaluations.

Minimum Protective Serum Concentrations of Pneumococcal Anti-Capsular Antibodies in Infant Rats (1998)

Infant rats were passively immunized to determine the protective capacity of pneumococcal anticapsular antibodies. Animal-passaged strains of Streptococcus pneumoniae serotypes 1, 4, 5, 6b, 7f, 9v, 14, 18c, 19f, and 23f were used as challenge inocula (1-1500 cfu) in a model of pulmonary infection that resulted in bacteremia, meningitis, and death. From untreated control animals, histologic sections of lung demonstrated infiltrative pneumonia and lung homogenate cultures grew S. pneumoniae at concentrations of 10(3)-10(8) cfu per gram of lung tissue. A type-specific anti-capsular antibody serum concentration of 0.1-1.15 microg/mL resulted in a statistically significant reduction in mortality compared with the reduction in untreated controls, except for serotype 14, which required 2.32 microg/mL for a significant reduction in mortality. The serum antibody level that provided 50% reduction in mortality ranged from 0.1-3.5 microg/mL for all serotypes.
Vasodilator action of docosahexaenoic acid (DHA) in human coronary arteries in vitro. (2007)

Coronary arterial tissues obtained from mammalian hearts are known to develop spontaneous phasic contractions. The aim of the present study was to investigate the vasodilatory effects of docosahexaenoic acid (DHA) on the rhythmic contractions of isolated human coronary arterial (HCA) preparations obtained from the recipient hearts of patients undergoing cardiac transplantation. Results from 8 hearts show that: (i) most HCA tissues displayed spontaneous rhythmic phasic contractions with a cycle length around 10 min in the absence or presence of PGF2alpha or elevated [K+]0 (20 mM); (ii) the rhythmic activity could be suppressed by a free fatty acid DHA (30 microM); (iii) high [K+]0 (20 and 80 mM) could induce sustained tonic contraction in addition to phasic contractions in HCA tissues, the tonic contraction could be antagonized by L-type Ca(2+) channel blockers or by DHA (depending on [K+]0); (iv) a digitalis substance ouabain also could induce tonic contraction and suppress phasic contraction; (v) in isolated HCA vascular smooth muscle cells, DHA increased the magnitude of outward voltage-gated K+ (IKV) currents and the inwardly rectifying IK1 currents. Enhancement of K+ currents could be related to vasorelaxation induced by DHA in HCA preparations. Further studies on the effects of DHA on various ionic currents and intracellular Ca(2+) transient are needed to clarify the Ca(2+)-dependent and the Ca(2+)-independent actions of DHA in HCA.
COP9 signalosome subunits 4 and 5 regulate multiple pleiotropic pathways in<i>Drosophila melanogaster</i> (2002)

The COP9 signalosome (CSN) is an essential eight-subunit repressor of light-regulated development in Arabidopsis. This complex has also been identified in animals, though its developmental role remains obscure. CSN subunits have been implicated in various cellular processes, suggesting a possible role for the CSN as an integrator of multiple signaling pathways. In order to elucidate the function of the CSN in animals, a Drosophila model system has previously been established. Gel-filtration analysis with antibodies against CSN subunits 4, 5 and 7 revealed that these proteins act as a complex in Drosophila that is similar in size to the plant and mammalian complexes. Null mutations in either one of two subunits, CSN4 or CSN5, are larval lethal. Successful embryogenesis appears to be a consequence of maternal contribution of the complex. Biochemical analysis indicates that the different subunits are found in both CSN-dependent and CSN-independent forms, and that these forms are differentially affected by the mutations. Phenotypic characterization of these two mutants indicates that they show both shared and unique phenotypes, which suggest specific roles for each subunit. Both mutants have defective oocyte and embryo patterning, and defects in response to DNA damage, while csn5 mutants develop melanotic tumors and csn4 mutants have phenotypes reminiscent of defects in ecdysone signaling.

Teacher’s Attitude towards Work Influence Job Satisfaction: An Imminent Stimulus Study for Approaching Pollster’s (2017)

The issue of job satisfaction has dependably pulled in incredible consideration among analysts in consisting of enterprise, different fields, enterprise and general society division. This examine is an strive to analyze or to find out the influence of Attitude Towards Work (ATW) on job satisfaction among high school teachers particularly in aided and unaided sectors of Bangalore. To gain the goal, a questionnaire became established and was administered to a sample of 1294 many of the excessive school instructors, teaching in aided and unaided sectors in Bangalore. After assembling the questionnaires the quantitative information was sorted, roundabout as well as broke down primarily supported upon the fundamental topics as well as individual study speculation. The consequences exposed that Attitudes toward work has a positive significant sway on Job Satisfaction (s =0.199; CR=3.208, p<0.05). The results offer us with a better expertise of the nature of the hypotheses designates that ATW has a important consequence on job satisfaction as well as performance in a better way of the teachers selected under the sample study. Perhaps, the attitude might not hold an influencing factor on job satisfaction in business sector.
