Smart Contract-Based Product Traceability System in the Supply Chain Scenario (2019)

With the improvement of living standard, people begin to pay more attention to food safety and product quality. Therefore, for consumers, it is necessary to establish a reliable system that can trace the source of products. However, most existing traceability systems tend to lack transparency, data is primarily stored within the enterprise, and the cost of tampering with data is very low. Besides, the supply chain nodes are easy to evade responsibility when product safety or quality issues arise under the traditional centralized management model, and it is difficult to trace the root of issues. The development of blockchain technology provides us with new ideas for realizing the traceability of products in supply chain scenarios. Due to its characteristics of decentralization, transparency, and immutability, blockchain can be effectively used to alleviate the above problems. In this paper, we propose a product traceability system based on blockchain technology, in which all product transferring histories are perpetually recorded in a distributed ledger by using smart contracts and a chain is formed that can trace back to the source of the products. In particular, we design an event response mechanism to verify the identities of both parties of the transaction, so that the validity of the transaction can be guaranteed. And all events are permanently stored in the form of logs as a basis for handling disputes and tracking responsible entities. Furthermore, a system prototype is constructed based on the testing framework of Truffle. The contract code is deployed on a test network TestRpc that runs in local memory, and a decentralized web page interface is implemented based on the prototype. Finally, the system security analysis and experimental results show that our solution is feasible.
Correlation of External and Internal Monitoring of Uterine Activity in a Cohort of Term Patients (2001)

External tocodynamometry (ET) and intrauterine pressure monitoring (IUPC) are commonly used to assess uterine contractile activity. It is believed that ET does not accurately document contraction amplitude. However, no direct comparison of ET and IUPC has been published in term patients. Our objective was to determine the correlation between frequency, duration, and amplitude as measured by ET and IUPC. Twenty patients between 36 and 41 weeks' gestation were enrolled during active spontaneous labor. Uterine contractions were recorded simultaneously by ET and IUPC for 2 hours. ET and IUPC data were compared using the Spearman correlation coefficient and the Wilcoxon signed-rank test. The median body mass index (BMI) of the patient population was 31.8 kg/m2 (range 22.2 to 42.3). There was good correlation of contraction frequency measured by ET and IUPC (r = 0.75, p = 0.001), but poor correlation of both contraction amplitude (r = 0.26) and duration (r = 0.27). ET and IUPC assessment of uterine contractile activity, specifically contraction amplitude and duration, do not appear to correlate in a population of moderately obese patients. This suggests that ET should not exclusively be relied upon in this population to assess uterine contractile activity during labor.
Serum protein pattern in normal pregnancy with special reference to acute‐phase reactants (1983)

The concentrations of acute-phase protein reactants, total protein, albumin and globulin fractions were measured throughout normal pregnancy in 27 women. alpha 1-Antitrypsin and caeruloplasmin concentrations increased gradually to reach their highest levels in the third trimester. Orosomucoid and haptoglobin showed similar patterns: higher levels in the first and third trimester with a decline around 24 weeks gestation. C-Reactive protein showed levels similar to those of non-pregnant healthy individuals (less than 5 mg/l) throughout pregnancy. alpha 1-, alpha 2- and beta-Globulin concentrations increased from the first trimester towards term. gamma-Globulin concentration changed little during gestation. The data obtained provide reference ranges for serum proteins in healthy pregnancy.
The function and regulation of <i>cut</i> expression on the wing margin of <i>Drosophila</i>: Notch, Wingless and a dominant negative role for Delta and Serrate (1997)

We have investigated the role of the Notch and Wingless signaling pathways in the maintenance of wing margin identity through the study of cut, a homeobox-containing transcription factor and a late-arising margin-specific marker. By late third instar, a tripartite domain of gene expression can be identified about the dorsoventral compartment boundary, which marks the presumptive wing margin. A central domain of cut- and wingless-expressing cells are flanked on the dorsal and ventral side by domains of cells expressing elevated levels of the Notch ligands Delta and Serrate. We show first that cut acts to maintain margin wingless expression, providing a potential explanation of the cut mutant phenotype. Next, we examined the regulation of cut expression. Our results indicate that Notch, but not Wingless signaling, is autonomously required for cut expression. Rather, Wingless is required indirectly for cut expression; our results suggest this requirement is due to the regulation by wingless of Delta and Serrate expression in cells flanking the cut and wingless expression domains. Finally, we show that Delta and Serrate play a dual role in the regulation of cut and wingless expression. Normal, high levels of Delta and Serrate can trigger cut and wingless expression in adjacent cells lacking Delta and Serrate. However, high levels of Delta and Serrate also act in a dominant negative fashion, since cells expressing such levels cannot themselves express cut or wingless. We propose that the boundary of Notch ligand along the normal margin plays a similar role as part of a dynamic feedback loop that maintains the tripartite pattern of margin gene expression.
Reduction in slow intercompartmental clearance of urea during dialysis. (1985)

The kinetics of urea and inulin were analyzed in five anesthetized dogs during sequential 2-hour periods before, during, and after hemodialysis. The distribution of both compounds after simultaneous intravenous injection was characterized by three-compartment models, and the total volumes of urea (0.66 +/- 0.05 L/kg) and inulin (0.19 +/- 0.01 L/kg) distribution were similar to expected values for total body water and extravascular space, respectively. Intercompartmental clearances calculated before dialysis were used to estimate blood flows to the fast and slow equilibrating compartments. In agreement with previous results, the sum of these flows was similar to cardiac output, averaging 101% of cardiac output measured before dialysis (range 72% to 135%). Dialysis was accompanied by reductions in the slow intercompartmental clearances of urea (81%) and inulin (47%), which reflected a 90% attenuation in blood flow supplying the slow equilibrating compartments. This was estimated to result in a 10% average reduction in the efficiency with which urea was removed by dialysis (range 2.0% to 16.4%). Mean arterial pressure fell by less than 5% during dialysis, but total peripheral resistance increased by 47% and cardiac output fell by 35%. In the postdialysis period, total peripheral resistance and cardiac output returned toward predialysis values, but blood flow to the slow equilibrating peripheral compartment was still reduced by 80%. These changes parallel activation of the renin-angiotensin system, but further studies are required to establish causality.
Likelihood Distributions for Estimating Functions when Both Variables are Subject to Error (1967)

When the data for estimating a function contains errors in the independent variable, the likelihood contains the unknown true values of the independent variable as nuisance parameters. These can be eliminated from the likelihood to give a new likelihood which resembles a normal distribution with variances which depend on the unknown function. The resulting least squares equations have variable weights, and must be solved by an iterative procedure.
Enhanced Hammerstein Behavioral Model for Broadband Wireless Transmitters (2011)

A novel enhanced Hammerstein behavior model consisting of a weighted memoryless polynomial followed by a Volterra filter is proposed. The weighted polynomial is used for predicting the strong static nonlinear behaviors of the power amplifiers (PAs). Since the Volterra filter is employed only for the mild dynamic nonlinearities, the filter can be implemented with low nonlinear order. Thus, this proposed model is capable of predicting both the static and dynamic nonlinearities of RF PAs with the acceptable complexity. The modeling performance of the proposed model is assessed in terms of in-band and out-of-band errors, such as normalized mean square error and adjacent channel error power ratio, and it is compared with a conventional Hammerstein, an augmented Hammerstein, and a Volterra series with respect to computation complexities such as the number of floating point operations and coefficients. The excellent estimation capability of the enhanced Hammerstein model is validated by two kinds of PAs: Si lateral diffusion metal-oxide-semiconductor and GaN high electron-mobility transistor amplifiers. Furthermore, the proposed scheme is applied to the digital predistortion (DPD) to cancel the nonlinearities of the PAs. The modeling performances and DPD experimental results clearly demonstrate the superiority of the enhanced Hammerstein scheme: the computational complexity is comparable with the augmented Hammerstein behavioral model, but the modeling performance is similar to the Volterra filter, which is the most accurate model.
La integración de estudios universitarios sin transmisión de elementos materiales, como supuesto de sucesión empresarial y sus efectos: A propósito de la sentencia del Tribunal Superior de Justicia de La Rioja de 5 de marzo de 2015 (2015)

En este trabajo, tomando como referencia la Sentencia del Tribunal Superior de Justicia de La Rioja de 5 de marzo de 2015, se analiza si la integracion de estudios universitarios hasta el momento impartidos por una Escuela Universitaria en la Universidad de la Rioja puede ser calificada como un supuesto de sucesion de empresa de los contemplados en el art. 44 ET, asi como los requisitos que deben cumplirse para que ello sea posible. Asimismo, se procede al analisis de los efectos que de esta circunstancia pueden derivarse, en especial, en relacion con la determinacion del convenio colectivo que resulte de aplicacion a los trabajadores afectados por estos procesos de sucesion empresarial.
Growth of the photosynthetic bacterium Rhodopseudomonas capsulata chemoautotrophically in darkness with H2 as the energy source (1979)

The phototrophic bacterium Rhodopseudomonas capsulata was found to be capable of growing chemoautotrophically under aerobic conditions in darkness. Growth was strictly dependent on the presence of H2 as the source of energy and reducing power, O2 as the terminal electron acceptor for energy transduction, and CO2 as the sole carbon source; under optimal conditions the generation time was about 6 h. Chemoautotrophically grown cells showed a relatively high content of bacteriochlorophyll a and intracytoplasmic membranes (chromatophores). Experiments with various mutants of R. capsulata, affected in electron transport, indicate that either of the two terminal oxidases of this bacterium can participate in the energy-yielding oxidation of H2. The ability of R. capsulata to multiply in at least five different physiological growth modes suggests that it is one of the most metabolically versatile procaryotes known.
Iterative retrieval of surface emissivity and temperature for a hyperspectral sensor (1997)

The central problem of temperature-emissivity separation is that we obtain N spectral measurements of radiance and need to find N + 1 unknowns (N emissivities and one temperature). To solve this problem in the presence of the atmosphere we need to find even more unknowns: N spectral transmissions {tau}{sub atmo}({lambda}) up-welling path radiances L{sub path}{up_arrow}({lambda}) and N down-welling path radiances L{sub path}{down_arrow}({lambda}). Fortunately there are radiative transfer codes such as MODTRAN 3 and FASCODE available to get good estimates of {tau}{sub atmo}({lambda}), L{sub path}{up_arrow}({lambda}) and L{sub path}{down_arrow}({lambda}) in the order of a few percent. With the growing use of hyperspectral imagers, e.g. AVIRIS in the visible and short-wave infrared there is hope of using such instruments in the mid-wave and thermal IR (TIR) some day. We believe that this will enable us to get around using the present temperature - emissivity separation (TES) algorithms using methods which take advantage of the many channels available in hyperspectral imagers. The first idea we had is to take advantage of the simple fact that a typical surface emissivity spectrum is rather smooth compared to spectral features introduced by the atmosphere. Thus iterative solution techniques can be devised which retrieve emissivity spectra {epsilon} based on spectral smoothness. To make the emissivities realistic, atmospheric parameters are varied using approximations, look-up tables derived from a radiative transfer code and spectral libraries. By varying the surface temperature over a small range a series of emissivity spectra are calculated. The one with the smoothest characteristic is chosen. The algorithm was tested on synthetic data using MODTRAN and the Salisbury emissivity database.
Automatic seismic wave arrival detection and picking with stationary analysis: Application of the KM2O-Langevin equations (2007)

Abstract An automatic detection and a precise picking of the arrival times of seismic waves using digital seismograms are important for earthquake early detection systems. Here we suggest a new method for detecting and picking P -and S -wave signals automatically. Compared to methods currently in use, our method requires fewer assumption with properties of the data time series. We divide a record into intervals of equal lengths and check the “local and weak stationarity” of each interval using the theory of the KM 2 O-Langevin equations. The intervals are stationary when these include only background noise, but the stationarity breaks abruptly when a seismic signal arrives and the intervals include both the background noise and the P -wave. This break of stationarity makes us possible to detect P -wave arrival. We expand the method for picking of S -waves. We applied our method to earthquake data from Hi-net Japan, and 90% of P -wave auto-picks were found to be within 0.1 s of the corresponding manual picks, and 70% of S -wave picks were within 0.1 s of the manual picks. This means that our method is accurate enough to use as a part of the seismic early detection system.
A Solution for Secure Certified Electronic Mail Using Blockchain as a Secure Message Board (2019)

The certified mail is a value-added service that is widely used in the paper world. However, the scientific community has not yet provided a solution for certified e-mail that has achieved widespread acceptance. This lack of a certified e-mail solution is not due to a lack of proposed approaches; because over the past 40 years, more than 100 protocols have been reported in journals and at conferences. The vast majority of these proposed protocols use a trusted third party (TTP) to achieve fairness. The few solutions without a TTP have not been successful due to their high computational and/or communication cost. Blockchain provides a new approach to develop the protocols without a TTP but without the prior drawbacks of the previous solutions without a TTP. Here, we present a new protocol for certified e-mail based on a blockchain without a conventional TTP that is integrated with the conventional e-mail infrastructure. The protocol is secure, efficient, and viable from a practical perspective.
Sintering Behavior of 0.8 mol%‐CuO‐Doped 3Y‐TZP Ceramics (2005)

In recent years, 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP) doped with copper oxide has obtained increasing interest due to its enhanced superplastisity and good potential in tribological applications. In this work, the effect of addition of small amounts (0.8 mol%) of copper oxide on the sintering behavior of 3Y‐TZP was studied using a dilatometer and high‐temperature X‐ray diffraction (XRD). A qualitative sintering model was established based on several reactions during sintering as indicated by thermal analysis and XRD. Some of these reactions remarkably retard densification and consequently result in low final density (86%) of the sample sintered at 1400°C in air. The reaction between molten Cu 2 O and yttria as segregated to the Y‐TZP grain boundaries at around 1180°C leads to the depletion of yttria from Y‐TZP grains, which results in the formation of monoclinic phase during cooling. A relatively higher oxygen partial pressure can inhibit the dissociation of CuO to Cu 2 O. This inhibition in dissociation is one of the reasons why a dense (>96%) 0.8 mol% CuO‐doped 3Y‐TZP ceramic can be obtained after sintering at 1400°C in flowing oxygen.
Experimental Animal Models in Pancreatic Carcinogenesis: Lessons for Human Pancreatic Cancer (2001)

The silent course of pancreatic cancer and its explosive fatal outcome have hindered studies of tumor histogenesis and the identification of early biochemical and genetic alterations that could help to diagnose the disease at a curable stage and develop therapeutic strategies. Experimental animal models provide important tools to assess risk factors, as well as preventive and therapeutic possibilities. Although several pancreatic cancer models presently exist, only models that closely resemble human tumors in morphological, clinical, and biological aspects present useful media for preclinical studies. Because an estimated 70% of human tumors are induced by carcinogens and because a significant association has been found between cigarette smoking and pancreatic cancer, chemically induced models are of particular value. Moreover, in such models the etiology, modifying factors, effects of diets, and naturally occurring products can be studied and early diagnostic, preventive, and therapeutic possibilities sought out. Many of the existing models are described in this review, and the advantages and shortcomings of each model and their clinical implications are discussed.

Renal Dysfunction after Myocardial Revascularization: Risk Factors, Adverse Outcomes, and Hospital Resource Utilization (1998)

Many patients having elective myocardial revascularization develop postoperative renal dysfunction and failure, which are associated with prolonged intensive care unit and hospital stays, significant increases in mortality, and greater need for specialized long-term care. Resources should be redirected to mitigate renal injury in high-risk patients.
Whiplash Injury Sustained in Motor Vehicle Accidents: Factors Influencing Time Off Work (2001)

1030 cases of whiplash injury of the cervical spine were studied over an 8 year period to determine which factors affected the length of time off work. Early onset of neck pain, radiation of the neck pain into the upper limbs and older age group were associated with a greater mean time off work.An association between occupation and mean time off work is identified. Work of a heavy manual nature did not militate against a relatively early return to work. Those who drove for a living took the longest mean time off work.
[Susceptibility of Bithynia inflata mollusks from different populations to Opisthorchis felineus infestation]. (1987)

The paper reports the results of experimental infection of a specific intermediate host, molluscs Bithynia inflata from differently susceptible populations, with Opisthorchis felineus in one opisthorchis nidus. Non-susceptibility of molluscs from resistant and hyperinfected populations to O. felineus infection is shown.
Translating nature: river restoration as nature – culture (2000)

In this paper we examine the process of river restoration at the river Cole in southern England. We argue that analysing such environmental transformations as actor-network translations or ‘nature-cultures’ can provide an integrative perspective on the process of restoration and its intertwining of natural and human actors and help to avoid the traps of defining ‘nature’ and separating it from society; traps which open up before environmental philosophy when examining restoration. However, a translation perspective is less helpful in evaluating or prescribing restoration as environmental management.
