The Literature Review of Technology Acceptance Model: A Study of the Bibliometric Distributions

Technology acceptance model plays a signified issue in the information systems field since this theory was introduced by Davis in 1989. This paper investigates the features of technology acceptance model literature based on bibliometric method. By searching the ISI Web of knowledge database under the keyword of “technology acceptance model,” 689 articles were retrieved and analyzed though growth of the literatures and citation, document type, publication countries, subject area, keyword analysis are addressed. The distribution of journal paper was also examined using Bradford’s law and Lotka’s law. As the result, this research found that technology acceptance model literature has a steady growth as well as the citations. Relevant articles were concentrating on computer science, information systems, management, information science, and library science. The author productivity distribution data in technology acceptance literature was consistent with Lotka’s law. Furthermore, eight core journals were identified utilizing the Bradford’s law.
Integrated Symbol, Engine Table and Heap Memory Management in Multi-Engine Prolog

We describe an integrated solution to symbol, heap and logic engine memory management in a context where exchanges of arbitrary Prolog terms occur between multiple dynamically created engines, implemented in a new Java-based experimental Prolog system. As our symbols represent not just Prolog atoms, but also handles to Java objects (including arbitrary size integers and decimals), everything is centered around a symbol garbage collection algorithm ensuring that external objects are shared and exchanged between logic engines efficiently. Taking advantage of a tag-on-data heap representation of Prolog terms, our algorithm performs in-place updates of live symbol references directly on heap cells. With appropriate fine tuning of collection policies our algorithm provides a simple integrated memory management solution for Prolog systems, with amortized cost dominated by normally occurring heap garbage collection costs.
Global alteration in perfusion response to increasing oxygen consumption in patients with single-vessel coronary artery disease.

BACKGROUND Recent evidence suggests that, in coronary artery disease (CAD), myocardial blood flow (MBF) regulation is abnormal in regions supplied by apparently normal coronary arteries. However, the relation between this alteration and MBF response to increasing metabolic demand has not been fully elucidated. METHODS AND RESULTS MBF was assessed at baseline, during atrial pacing tachycardia, and after dipyridamole (0.56 mg/kg IV over 4 minutes) in 9 normal subjects and in 24 patients with ischemia on effort, no myocardial infarction, and isolated left anterior descending (n = 19) or left circumflex (n = 5) coronary artery stenosis (> or = 50% diameter narrowing). Perfusion of both poststenotic (S) and normally supplied (N) areas was measured off therapy by positron emission tomography and [13N]ammonia. Normal subjects and CAD patients showed similar rate-pressure products at baseline, during pacing, and after dipyridamole. In CAD patients, MBF was lower in S than in N territories at rest (0.68 +/- 0.14 versus 0.74 +/- 0.18 mL.min-1.g-1, respectively, P < .05), during pacing (0.92 +/- 0.29 versus 1.16 +/- 0.40 mL.min-1.g-1, respectively, P < .01), and after dipyridamole (1.18 +/- 0.34 versus 1.77 +/- 0.71 mL.min-1.g-1, respectively, P < .01). However, normal subjects showed significantly higher values of MBF both at rest (0.92 +/- 0.13 mL.min-1.g-1, P < .05 versus both S and N areas), during pacing tachycardia (1.95 +/- 0.64 mL.min-1.g-1, P < .01 versus both S and N areas), and after dipyridamole (3.59 +/- 0.71 mL.min-1.g-1, P < .01 versus both S and N areas). The percent change in flow was strictly correlated with the corresponding change in rate-pressure product in normal subjects (r = .85, P < .01) but not in either S (r = .04, P = NS) or N regions (r = .08, P = NS) of CAD patients. CONCLUSIONS Besides epicardial stenosis, further factors may affect flow response to increasing metabolic demand and coronary reserve in patients with CAD.
Non-Enzymatic Glucose Sensing Using Carbon Quantum Dots Decorated with Copper Oxide Nanoparticles

Perturbations in glucose homeostasis is critical for human health, as hyperglycemia (defining diabetes) leads to premature death caused by macrovascular and microvascular complications. However, the simple and accurate detection of glucose in the blood at low cost remains a challenging task, although it is of great importance for the diagnosis and therapy of diabetic patients. In this work, carbon quantum dots decorated with copper oxide nanostructures (CQDs/Cu2O) are prepared by a simple hydrothermal approach, and their potential for electrochemical non-enzymatic glucose sensing is evaluated. The proposed sensor exhibits excellent electrocatalytic activity towards glucose oxidation in alkaline solutions. The glucose sensor is characterized by a wide concentration range from 6 µM to 6 mM, a sensitivity of 2.9 ± 0.2 µA·µM−1·cm−2, and a detection limit of 6 µM at a signal-to-noise ratio S/N = 3. The sensors are successfully applied for glucose determination in human serum samples, demonstrating that the CQDs/Cu2O-based glucose sensor satisfies the requirements of complex sample detection with adapted potential for therapeutic diagnostics.

Quantitative trait locus mapping in an F 2 Duroc × Pietrain resource population : II . Carcass and meat quality traits 1

Pigs from the F2 generation of a Duroc × Pietrain resource population were evaluated to discover QTL affecting carcass composition and meat quality traits. Carcass composition phenotypes included primal cut weights, skeletal characteristics, backfat thickness, and LM area. Meat quality data included LM pH, temperature, objective and subjective color information, marbling and firmness scores, and drip loss. Additionally, chops were analyzed for moisture, protein, and fat composition as well as cook yield and Warner-Bratzler shear force measurements. Palatability of chops was determined by a trained sensory panel. A total of 510 F2 animals were genotyped for 124 microsatellite markers evenly spaced across the genome. Data were analyzed with line cross, least squares regression interval, mapping methods using sex and litter as fixed effects and carcass weight or slaughter age as covariates. Significance thresholds of the F-statistic for single QTL with
Improved offline signature verification scheme using feature point extraction method

In this paper a novel offline signature verification scheme has been proposed. The scheme is based on selecting 60 feature points from the geometric centre of the signature and compares them with the already trained feature points. The classification of the feature points utilizes statistical parameters like mean and variance. The suggested scheme discriminates between two types of originals and forged signatures. The method takes care of skill, simple and random forgeries. The objective of the work is to reduce the two vital parameters False Acceptance Rate (FAR) and False Rejection Rate (FRR) normally used in any signature verification scheme. In the end comparative analysis has been made with standard existing schemes.
Bleeding and perforation after outpatient colonoscopy and their risk factors in usual clinical practice.

BACKGROUND & AIMS The most widely quoted complication rates for colonoscopy are from case series performed by expert endoscopists. Our objectives were to evaluate the rates of bleeding, perforation, and death associated with outpatient colonoscopy and their risk factors in a population-based study. METHODS We identified all individuals 50 to 75 years old who underwent an outpatient colonoscopy during April 1, 2002, to March 31, 2003, in British Columbia, Alberta, Ontario, and Nova Scotia, Canada. Using administrative data, we identified all individuals who were admitted to hospital with bleeding or perforation within 30 days following the colonoscopy in each province. We calculated the pooled rates of bleeding and perforation from the 4 provinces. In Ontario, we abstracted the hospital charts of all deaths that occurred within 30 days following the procedure. We used generalized estimating equations models to evaluate factors associated with bleeding and perforation. RESULTS We identified 97,091 persons who had an outpatient colonoscopy. The pooled rates of colonoscopy-related bleeding and perforation were 1.64/1000 and 0.85/1000, respectively. The death rate was 0.074/1000 or approximately 1/14,000. Older age, male sex, having a polypectomy, and having the colonoscopy performed by a low-volume endoscopist were associated with increased odds of bleeding or perforation. CONCLUSIONS Although colonoscopy has established benefits for the detection of colorectal cancer and adenomatous polyps, the procedure is associated with risks of serious complications, including death. Older age, male sex, having a polypectomy, and having the procedure done by a low-volume endoscopist were independently associated with colonoscopy-related bleeding and perforation.
Formation of Nonequilibrium Magnetic Nanoparticle Structures in a Large Alternating Magnetic Field and Their Influence on Magnetic Hyperthermia Treatment

We simultaneously simulated thermally activated magnetization reversal and magnetic torque-driven rotation of mono- and polydisperse magnetite nanoparticles exposed to a large alternating magnetic field. We found that if the nanoparticles are rotatable, their easy axes are stationarily oriented to the directions parallel, perpendicular, or oblique to the magnetic field, depending on the relative conditions between the size of the nanoparticles and the amplitude and frequency of the magnetic field. The formations of such nonequilibrium oriented structures lead to significant variations of dynamic hysteresis loops. This knowledge would help reconcile good efficacy with a low side-effect profile in targeted magnetic thermotherapy using magnetite nanoparticles.
Reflected Solar Radiances from Regional Scale Scenes

Abstract A set of bi-directional reflectance models is presented for various atmospheric scene types. The models were composited from data collected from an aircraft platform in May-July 1979 during Summer MONEX. The space scale of the composited models is generally from 250 to 1000 km, which corresponds to the scale of interest in climate monitoring and modeling. Composite models for the following scene types are presented: the desert sands of the Saudi Arabian Empty Quarters, the Himalayan mountains, the Arabian Sea with the ever-present fair weather cumulus cloudiness, the semi-arid agricultural land surface of the Indian subcontinent under pre-monsoon conditions, broken middle and low level clouds over ocean, an altostratus cloud deck, and the broken pack-ice fields of Hudson Bay. Nearly all the models display a degree of anisotropy such that serious errors (10–100%) would result in the reflected flux density isotropically inferred from some of the reflected radiances. The features of many of the mode.
Geometry of crustal faults: Identification from seismicity and implications for slip and stress transfer models

Geometric complexities of faults and fault systems are first‐order effects that complicate the mechanics of faulting and physics of earthquakes. We investigate the importance of this complexity using relocated seismicity from a catalog of events for the Joshua Tree–Landers earthquake sequence and present a new method to locate faults or fault systems in clouds of seismicity. The abundance and ever improved accuracy of earthquake and microseismic location of such events permits a better understanding of the geometric intricacies of fault systems. The proposed method assumes that seismicity is most abundant in the central fault zone and the spatial density of seismicity is used to locate finite width fault zones and construct fault surfaces from the seismicity. The method is different from statistical fits (e.g., L1‐ and L2‐norm fits) in that it does not suppose a decay of seismicity from the central fault zone and that it identifies the tiplines of faults from the fault zone seismicity directly. In the Joshua Tree–Landers earthquake catalog, the method identifies 10 separate fault segments ranging in average strike from north‐south to east‐west that compare well with surface trace fault maps. These faults exhibit significant nonplanarity with the Joshua Tree fault departing from a planar approximation by more than 2000 m. The mechanical effects of the geometrically complex fault surfaces are illustrated by inverting for coseismic slip using surface displacements and when compared to slip inversions on planar faults reveal a more complicated pattern of slip on the fault. The low RMS error in surface displacement, the good match to geodetic moment, and robust estimates of maximum slip compare well to the results for planar faults. The inverted slip distributions are used to solve the quasi‐static fault stress transfer problem and estimate the tractions changes by slip on the Joshua Tree fault on the fault segments involved in the Landers earthquake. We find that the propensity for slip on the Landers faults increased in regions of initiation and largest slip during the subsequent event. The geometrically complex models predict greater likelihood for slip along the northern faults involved in the Landers earthquake than the commonly used planar and vertical four‐fault models.
Hydrodynamics as a Major Factor Controlling the Occurrence of Green Macroalgal Blooms in a Eutrophic Estuary: A Case Study on the Influence of Precipitation and River Management

Abstract Data on the variation of physicochemical parameters, biomass and growth of green macroalgae (mostlyEnteromorpha ) collected between January 1993 and January 1997 in the Mondego Estuary (western coast of Portugal) was analysed with the aim to identify the factors that control opportunistic macroalgal abundance in the system. The annual biomass of Enteromorpha spp. is strongly dependent on the amount of fresh water that enters the system during winter and spring. In turn, the input of fresh water is regulated by precipitation and by river management practices. The optimization of the rice crops from the upstream valley depends on their water level, which determines the number of days and hours per day during which sluice gates remain open in winter and spring. River flow has significant impacts on salinity, N:P ratios, current velocities and light extinction coefficients within the system. The interaction of all these factors controls macroalgal growth and biomass loss processes. In winters and springs during which sluice gates are often closed due to water deficiency of the rice fields (dry winter and spring or dry winter followed by rainy spring), little fresh water enters the system and consequently, salinity remains high, N:P ratios around 20, light penetration increases, and current velocities fall. These conditions facilitate macroalgal fixation, enhance their growth and spring blooms occur. On the contrary, during winters and springs when fresh water is in excess of rice fields' needs (rainy winters and springs), sluice gates remain open for long periods of time. High input of fresh water to the system causes salinity and light penetration to decrease, while N:P ratios and current velocities increase. These conditions contribute both to reduced Enteromorpha growth and higher loss of macroalgal biomass from the system to the ocean. The present work shows that the inter-annual variation of macroalgal biomass in the Mondego Estuary is controlled by hydrodynamics, which in turn depends on precipitation and on river management, according with the water needs of the upstream rice crop.
CD4 T-Cell Responses to Herpes Simplex Virus Type 2 Major Capsid Protein VP5: Comparison with Responses to Tegument and Envelope Glycoproteins

ABSTRACT We used CD4 lymphocyte clones from herpes simplex virus type 2 (HSV-2) lesions or the cervix and molecular libraries of HSV-2 DNA to define HSV-2 major capsid protein VP5 and glycoprotein E (gE) as T-cell antigens. Responses to eight HSV-2 glycoprotein, tegument, nonstructural, or capsid antigens were compared in 19 donors. Recognition of VP5 and tegument VP22 were similar to that of gB2 and gD2, currently under study as vaccines. These prevalence data suggest that HSV capsid and tegument proteins may also be candidate vaccine antigens.
Mantle provinces under North America from multifrequency P wave tomography

This is a survey of mantle provinces (large‐scale seismic anomalies) under North America, from the surface down to 1500–1800 km depth. The underlying P velocity model was obtained by multifrequency tomography, a waveform‐based method that systematically measures and models the frequency‐dependence of teleseismic body waves. A novel kind of three‐dimensional rendering technique is used to make the considerable structural complexities under North America accessible. In the transition zone and below, the North American mantle is dominated by seismically fast provinces, which represent distinct subduction episodes of the Farallon plate. I attempt to date and interpret the various slab fragments by reconciling their present positions with paleotrench locations from plate tectonic reconstructions and with major geologic surface episodes. Differences in vertical sinking velocity have led to large vertical offsets across adjacent, coeval slabs. Some of the mantle provinces have not been discussed much previously, including (1) a seismically slow blanket overlying the oldest Farallon subduction along the eastern continental margin, (2) a transition zone slab coeval with the Laramide orogeny (ca. 80–60 Myr), which I discuss in analogy to the “stagnant slab” subduction style commonly found in the western Pacific today, (3) the lower mantle root of present‐day Cascadia subduction, which may have started out as intraoceanic subduction,(4) a lower mantle slab under Arizona and New Mexico, the last material to subduct before strike‐slip motion developed along the San Andreas boundary, and (5) two narrow plate tears thousands of kilometers long, one of which is the subducted conjugate of the Mendocino Fracture Zone.
Localized Maxillary Ridge Augmentation With a Block Allograft for Dental Implant Placement: Case Reports

Autogenous block bone grafts have been highly successful in treating human periodontal defects, restoring esthetics, and developing adequate bone volume for dental implant placement. Limitations in available donor bone, the need for an added surgical procedure, and other potential complications have made the use of allogenic bone graft materials an important alternative. One patient described in this report presented with fractured root syndrome of the right maxillary incisor with severe resorption of the buccal plate. After atraumatic tooth extraction, a staged treatment approach involving localized ridge augmentation with an allogenic iliac bone block material and dental implant placement was used. The host bone completely incorporated the graft with only minor resorption, which enabled the implant to be placed. The allogenic bone block material used in this study was an effective alternative to harvesting and grafting autogenous bone for implant site development. The cases presented in this article clinically demonstrate the efficacy of using a block allograft in generating effective new bone fill for dental implant placement.
Long Bone Shaft Robusticity and Body Proportions of the Saint-Césaire 1 Châtelperronian Neanderthal

The Châtelperronian Saint-Cesaire 1 Neanderthal partial skeleton exhibits an overall morphology similar to earlier Neanderthals, but it is associated with an early Upper Palaeolithic technological complex. To assess whether its habitual mechanical loading patterns from manipulative and locomotor behaviour were more similar to those of Middle Palaeolithic or earlier Upper Palaeolithic humans, we compared its long bone shaft geometric properties to those of European Neanderthals and early modern humans. As appropriate, body proportions of Neanderthals and European early modern humans were employed to scale diaphyseal strength. Saint-Cesaire 1 is similar to Neanderthals in its rounded proximal femoral shaft, lack of a femoral pilaster and rounded tibial crests, but it contrasts with Neanderthals in its pronounced humeral deltoid tuberosity and dorsally projecting medial femoral buttress. In other diaphyseal cross-sections it is similar to members of both samples. In the lower limb, Saint-Cesaire 1 resembles both samples in robusticity when given Neanderthal proportions, but it appears hyper-robust when earlier Upper Palaeolithic human proportions are used. Its femoral midshaft exhibits the greater medio-lateral rigidity of the Neanderthals but resembles early modern humans in its elevated antero-posterior strength. The femoral diaphyseal shapes fit best with a model of Neanderthal pelvic and hip proportions, combined with an early modern human emphasis on antero-posterior loading of the femoral midshaft. In the upper limb, its cortical area distribution is closer to those of the Neanderthals, but its proximal diaphyseal shapes provide a mixed pattern. This Châtelperronian hominid therefore provides a mosaic in terms of diaphyseal loading patterns, but the load levels and patterns are reasonable for a Late Pleistocene human only if it is provided with the hyper-arctic body proportions of a Neanderthal.
Trends in aerosol radiative effects over China and Japan inferred from observed cloud cover, solar “dimming,” and solar “brightening”

[1] This study examines multidecadal changes in surface downward shortwave (SW) radiation flux, total cloud cover, SW cloud effect, and related parameters over China and Japan during 1960–2004 using monthly gridded data from the Global Energy Balance Archive, synoptic cloud reports, and the International Satellite Cloud Climatology Project. We use the concept of cloud cover radiative effect, defined as the change in downward SW flux produced by a change in cloud cover, to quantify and remove the impact of cloud cover anomalies on surface solar flux. This will allow radiative effects of long-term changes in anthropogenic aerosol to be more clearly distinguished from natural weather and climate variability. As fit by a linear trend between 1971 and 1989, surface solar flux decreased by a statistically significant 11 W m−2 per decade over China and decreased by a nonsignificant 1 W m−2 per decade over Japan. The small decline over Japan can be entirely explained by an increase in cloud cover, but changes in cloud cover made negligible contribution to the 1971–1989 solar flux trend over China. Between 1990 and 2002, surface solar flux increased by a statistically significant 8 W m−2 per decade over Japan and increased by a nonsignificant 4 W m−2 per decade over China. Half of the 1990–2002 solar flux trend over China and one third of the trend over Japan can be attributed to a reduction in cloud cover. The 1971–1989 decrease in surface solar flux over China and the 1990–2002 increase in surface solar flux over Japan are both spatially widespread and exhibit consistent sign across seasons.
