Pricing asian power under jump-fraction process (2012)

A framework for pricing Asian power options is developed when the underlying asset follows a jump-fraction process. The partial differential equation (PDE) in the fractional environment with jump is constructed for such option using general Itô's lemma and self-financing dynamic strategy. With the boundary condition, an analytic formula for the option with geometric average starting at any time before maturity is derived by solving the PDE, and the option with arithmetic average is evaluated in Monte Carlo simulation using control variate technique with the help of the above analytic solution. Overwhelming numerical evidence indicates that the technique proposed is computationally efficient and dramatically improves the accuracy of the simulated price. Moreover, this study will pave a novel way to copy with the option contracts based on thinly-traded assets like oil, or currencies or interest rates.Se desarrolla un marco para tasar las opciones energéticas asiáticas sometiendo el valor del activo subyacente a un método de fracciones discontinuas. La ecuación en derivadas parciales (EDP) en el entorno fraccional con salto se construye para una opción dada utilizando la fórmula general de Itô y una estrategia dinámica de autofinanciación. Con la condición límite, resolviendo la EDP se deriva una fórmula analítica para la opción con una media geométrica que empieza en cualquier momento antes de la madurez, y la opción con media aritmética se evalúa con simulación de Monte Carlo utilizando variables de control apoyadas en la citada solución analítica. Hay abrumadora evidencia numérica de que la técnica propuesta es eficiente en tiempo de cálculo y mejora espectacularmente la precisión del precio simulado. Es más, este estudio abrirá un nuevo camino que seguir en los contratos de opción de compra basados en bienes tan poco negociables como el petróleo, las divisas o los tipos de interés.
A new tetracycline resistance determinant, Tet H, from Pasteurella multocida specifying active efflux of tetracycline (1993)

The tetracycline resistance determinant on plasmid pVM111 from an avian strain of Pasteurella multocida mediates tetracycline resistance by a regulated active efflux mechanism. DNA coding for the determinant did not hybridize at high stringency with DNA representing a group of common tetracycline resistance determinants. The DNA sequence, however; revealed a structural gene and a repressor gene which had significant (37 to 64%) sequence similarities with previously described classes of efflux-type tetracycline resistance genes from members of the family Enterobacteriaceae. The new determinant has been assigned to class H.
Proliferative Response of Corneal Endothelial Cells from Young and Older Donors (2004)

HCEC from both young and older donors can proliferate in vitro in response to growth-promoting agents. Proliferation in the presence of multiple mitogens ceased when confluence was reached, indicating the formation of a contact-inhibited monolayer. In general, cells cultured from young donors were more responsive to the agents tested, but the relative response of HCEC to these agents was similar, regardless of donor age. The relative difference in the extent of the response of the same cell population to different mitogens suggests that these mitogens induce different downstream signals. The relatively robust proliferative response of HCEC to FBS may involve stimulation of multiple downstream signaling pathways may involve stimulation of multiple downstream signaling pathways and/or induce more sustained downstream signaling than the other growth-promoting agents tested.

Report by The Latin-American Committee on Pediatric Residencies (1979)

Since 1970, the Committee on International Child Health of the American Academy of Pediatrics has supported COPREP, The Latin American Committee for Promotion of Residency Programs in Pediatrics. During the coming year, 1978-1979, the Academy will phase out its present level of economic support and the Latin American group will continue more independently. A report, educational in nature, is in order at this time. BACKGROUND During the 12th International Pediatric Congress in Mexico City in 1968, the American Academy of Pediatrics proposed discussions concerning the quality and content of pediatric residencies in Latin America. Two years later this was brought to fruition in Paipa, Colombia as the First Seminar on Education for Pediatric Residents under the sponsorship of the Committee on International Child Health (COICH) of the American Academy of Pediatrics with the support of the Johnson and Johnson Institute for Pediatric Service. This Seminar was organized by a Committee of District X of the Academy, under the leadership of Dr. Jorge Camacho Gamba, Chairman of that District, and with consultation by Dr. Nelson Ordway, Chairman of the COICH. From this first seminar emerged COPREP, the Comité Latinoamericano para la Promocion de Programas de Residencia en Pediatria. This Committee has held a seminar on the training of pediatric residents every three years at the time of the Pan-American Congress of Pediatrics and elected committee membership at each seminar, one faculty member and one resident from each Latin-American district of the Academy plus a consultant from the previous committee for purposes of continuity.
Pretherapy quantitative measurement of circulating Epstein–Barr virus DNA is predictive of posttherapy distant failure in patients with early‐stage nasopharyngeal carcinoma of undifferentiated type (2003)

Within a group of patients with UICC Stage I-II NPC, the pretherapy plasma EBV DNA level was found to identify a poor-risk group with a probability of distant failure similar to that of patients with advanced stage disease. This group of patients may warrant management considerations currently applicable only to cases of Stage III-IV disease. The prognostic significance of designating Stage IIB disease as per the 1997 UICC staging was confirmed, although the pretherapy EBV DNA level appears to be a more powerful prognostic discriminator in patients with early-stage NPC.
A hybrid NFC–Bluetooth secure protocol for Credit Transfer among mobile phones (2013)

ABSTRACT The next‐generation networks improve people's quality of life with new services and applications. The evolution of Internet technologies also promoted the development of electronic commerce and the evolution of mobile payments. Near field communication (NFC) was proposed as a new short‐range wireless technology and can play an important role in such issues. Money transactions among mobile devices could play an important role in a near future in order to simplify and perform such operations safely. Furthermore, it is important that tasks are easy to perform. Then, this paper presents a mobile solution based on a peer‐to‐peer communication system for money transfer, based on NFC and Bluetooth communications. A hybrid communication protocol combining the security characteristics of NFC and better Bluetooth data transfer rates is proposed. The proposal was deployed in real environments, and it was evaluated, demonstrated, and validated with different NFC tags and the Bluetooth traffic was also analyzed. It was shown that system presents good response times. The solution offers a friendly user's interface and very easy to use, guaranteeing the security of money transfer, and it is ready for use.

NAD<sup>+</sup>metabolism and oxidative stress: the golden nucleotide on a crown of thorns (2012)

In the twentieth century, NAD+ research generated multiple discoveries. Identification of the important role of NAD+ as a cofactor in cellular respiration and energy production was followed by discoveries of numerous NAD+ biosynthesis pathways. In recent years, NAD+ has been shown to play a unique role in DNA repair and protein deacetylation. As discussed in this review, there are close interactions between oxidative stress and immune activation, energy metabolism, and cell viability in neurodegenerative disorders and ageing. Profound interactions with regard to oxidative stress and NAD+ have been highlighted in the present work. This review emphasizes the pivotal role of NAD+ in the regulation of DNA repair, stress resistance, and cell death, suggesting that NAD+ synthesis through the kynurenine pathway and/or salvage pathway is an attractive target for therapeutic intervention in age-associated degenerative disorders. NAD+ precursors have been shown to slow down ageing and extend lifespan in yeasts, and protect severed axons from degeneration in animal models neurodegenerative diseases.
The Efficacy of an Air-Cooling Vest to Reduce Thermal Strain for Light Armour Vehicle Personnel (2007)

Light armour vehicle (LAV) personnel are being subjected to high ambient temperatures and radiant heat loads for hours during recent deployments to Afghanistan. One option to reduce the heat strain of crew members is to use the existing air-conditioning discharge outlets as a source of cool air to provide microclimate cooling through an individual air-vest. In this study, seven males were exposed to either hot, dry (HD, 49 C, 10% relative humidity) or warm, humid (WH, 35 C, 70% relative humidity) conditions while either receiving (C) or not receiving (NC) cooling through an air-vest. Inlet temperatures during C were 20 C and 12 C for the HD and WH conditions, respectively, based on findings reported by Hanna (1). The air-vest was worn over a T-shirt and underneath the armour crew coveralls. Subjects also wore a fragmentation vest, helmet and gloves and sat for 3 hours during the heat-stress exposures. All subjects completed the 3 hours of heat-stress exposure during all conditions but the rise in rectal temperature approached 2 C during HD with NC. When C was provided the rise in rectal temperature was minimal throughout the heat stress. It was concluded that micro-climate conditioning was an effective way to reduce the thermal strain of LAV crew.
User authentication and identification on smartphones by incorporating capacitive touchscreen (2016)

Smartphones, while providing users ease of access to sensitive information on the go, also present severe security risks if an attacker is able to gain access to them. To strengthen the user authentication and identification in a smartphone, we develop a biometric authentication and identification system which uses the capacitive touchscreen that is featured in all current smartphones. Our methodology focuses on using the touchscreen as a sensor to capture the image of a user's ear, thumb or four fingers. We extract the capacitive raw data from the touched body part to obtain a capacitive image, and then use it to capture geometric features (e.g., length and width of a finger) and principal components. After that, we experiment with Support Vector Machine (SVM) and Random Forest (RF) classifiers to verify and also identify each user. We achieved the maximum authentication accuracy of 98.84% by four fingers with SVM, and maxinum identification accuracy of 97.61% by four fingers with RF.
Generation of mink cell focus-forming viruses by Friend murine leukemia virus: recombination with specific endogenous proviral sequences (1984)

A family of recombinant mink cell focus-forming viruses (MCF) was derived by inoculation of NFS mice with a Friend murine leukemia virus, and their genomes were analyzed by RNase T1-resistant oligonucleotide fingerprinting. The viruses were obtained from the thymuses and spleens of preleukemic and leukemic animals and were evaluated for dualtropism and oncogenicity. All these isolates induced cytopathic foci on mink cells but could be classified into two groups based on their relative infectivities for SC-1 (mouse) or mink (ATCC CCL64) cells. One group of Friend MCFs (F-MCFs) (group I) exhibited approximately equal infectivities for SC-1 and mink cells, whereas a second group (group II) infected mink cells 1,000- to 10,000-fold more efficiently than SC-1 cells. Structural analyses of the F-MCFs revealed that group I and group II viruses correlated with recombination of Friend murine leukemia virus with two distinct, but closely related, endogenous NFS proviral sequences. No correlation was found between the type of F-MCF and the tissue of origin or the disease state of the animal. Furthermore, none of the F-MCF isolates were found to be oncogenic in NFS/N or AKR/J mice. F-MCFs of both groups underwent extensive substitution of ecotropic sequences, involving much of the gag and env genes of group I F-MCFs and most of the gag, pol, and env genes of group II F-MCFs. All F-MCF isolates retained the 3' terminal U3 region of Friend murine leukemia virus. Comparison of the RNAs of the F-MCFs with RNAs of MCFs derived from NFS.Akv-1 or NFS.Akv-2 mice indicated that the F-MCFs were derived from NFS proviral sequences which are distinct from the sequences contained in NFS.Akv MCF isolates. This result suggested that recombination with particular endogenous proviral sequences to generate MCFs may be highly specific for a given murine leukemia virus.

Efectividad de la vacuna monovalente contra rotavirus en sitios de alta morbilidad y mortalidad por diarrea en las ciudades de Cartagena, Leticia, Neiva, Pitalito y Valledupar 2011 - 2012 (2012)

La diarrea sigue siendo una causa importante de morbilidad y mortalidad a nivel mundial. Se estima que cada ano entre 1,6 y 2,5% de los ninos menores de cinco anos mueren por causas relacionadas con la diarrea [1]. El rotavirus es uno de los agentes infecciosos mas importantes asociados a la diarrea y se ha estimado que causa entre el 30 y el 50% de casos de diarrea en busca de atencion de salud en todo el mundo. Fue identificado desde 1973 como uno de los agentes causantes de diarrea mas importantes de gastroenteritis en lactantes y ninos pequenos [2]. Es asociado con la aparicion anual de mas de 100 millones de casos de diarrea, 2 millones de hospitalizaciones y 400.000 muertes en todo el mundo [3-5].En America Latina, la media de episodios de diarrea en ninos menores de un ano oscilo entre 2,3 en Mexico y 1,5 en Chile [6]. Kane et al han llevado a cabo una revision sistematica de la frecuencia de rotavirus en ninos con diarrea que asisten a centros de salud u hospitales de la region. Ellos encontraron que la frecuencia de rotavirus en los estudios latinoamericanos varia de 33% en ninos con diarrea con tratamiento ambulatorio a 38% entre los ninos hospitalizados por dicho sindrome [5].
Bifurcation in parallel-connected buck converters under a democratic current sharing scheme (2002)

This paper describes the bifurcation phenomena of a system of parallel-connected DC/DC converters. The results provide useful information for the design of stable current sharing in a democratic (central-limit control) configuration. Computer simulations are performed to capture the effects of variation of some chosen parameters on the qualitative behaviour of the system. It is found that variation of the voltage feedback gains lead to standard period-doubling bifurcation. A discrete-time map is derived and analysis is presented to establish the possibility of the bifurcation phenomena.
Novel Capsular Polysaccharide Loci and New Diagnostic Tools for High-Throughput Capsular Gene Typing in Streptococcus suis (2016)

Nonserotypeable Streptococcus suis isolates have been reported in many studies, and 9 novel cps loci (NCLs) have already been identified in nonserotypeable isolates. Moreover, novel cps loci are continually being found. The main purpose of this study was to investigate the prevalence and characteristics of NCLs in S. suis isolates recovered between 2013 and 2015 in China. This study provides valuable genetic information for monitoring the variations within NCLs. Meanwhile, a fast and cost-effective 18-plex detection system that can simultaneously identify the currently recognized 17 NCLs was developed in this study. This system will serve as a valuable tool for detecting known and identifying additional novel cps loci among nonserotypeable S. suis isolates.
Volatile Constituents of the Aerial and Underground Parts of<i>Curcuma aromatica</i>Salisb. from India (1996)

ABSTRACT The leaves, petioles and rhizomes of Curcuma aromatica Salisb. (Zingiberaceae) from Assam, India, were subjected to steam distillation. The resulting essential oils were analyzed by high-resolution GC and GC/MS. The leaf, petiole and rhizome oils contained more than 51, 50 and 61 components respectively, of which 43, 41 and 53 constituents have been identified, accounting for about 96.8%, 86.3% and 86.3% of the bulk of the respective oils. The major components in the leaf, petiole and rhizome oils were found to be 1,8-cineole (20.0%, 8.8% and 9.3%, respectively), camphor (18.0%, 16.8% and 25.6%), germacrone (11.8%, 0.2% and 10.6%), isoborneol (6.4%, 6.8% and 8.2%) and camphene (9.4%, 1.2% and 7.4%). Additional notable constituents included limonene (8.6%) in the leaf oil, caryophyllene oxide (8.7%), patchouli alcohol (8.4%) and elsholtzia ketone (6.0%) in the petiole oil, and curzerenone (10.9%) in the rhizome oil.
Tax Policy and Economic Development: A Roundtable Assessment (1996)

Economic development continues to be a top policy issue for the state of Maine. Within the broad topic of economic development is the issue of tax policy, and the state continues to experiment with changes in traditional taxes, such as sales and income, as well as with newer approaches, such as Employment Tax Increment Financing. What works and what does not work? Can the state afford the potential loss of revenues associated with tax incentives? Who wins and who loses from these policies? To answer these questions, Maine Policy Review convened a panel of experts to review Maine’s record. Two represent state government and have been involved directly in the administration of tax incentives, Brian Mahany and Alan P. Brigham. They are joined by two policy analysts with expertise in economic development, Christopher "Kit" St. John and Charles Colgan. There is a surprising degree of consensus about the inevitability of tax incentives and the value of their judicious application. Yet, it also is clear that they are not the centerpiece of economic development policy, and their impacts on the equitable distribution of public funds must be monitored.
Developing an Expert System for Nursing Practice. (1984)

The American Nurses' Association has set eight Standards of Nursing Practice related to the nursing process. Computer-aided information systems intended to facilitate the nursing process must be designed to promote adherence to these professional standards. For each of the eight standards, the paper tells how a hypothetical expert system could help nurses to meet the standard. A prototype of such an expert system is being developed. The paper describes issues in conceptualizing clinical decision-making and developing decision strategies for the prototype system. The process of developing the prototype system is described.
DGS Dual Composite Right/LeftHanded Transmission Line (2008)

The planar dual composite right/left-handed transmission line (D-CRLH TL) using a defected ground structure (DGS) and stub with rectangular patch is presented. The required series parallel resonance tank and shunt series resonance tank for the D-CRLH TL are provided by DGS and stub with rectangular patch, respectively. Its equivalent circuit is provided to analyze D-CRLH TL. The characteristics such as dispersion relation and frequency response of D-CRLH TL are analyzed by circuit analysis, Bloch-Floquet theory, and full wave simulation. The measured results of dispersion curves and frequency behaviors have good agreements with theory. Finally, it is shown that compact multiband resonator using proposed D-CRLH TL can be realized.
Inactivation of enteroviruses, rotaviruses and bacteriophages by peracetic acid in a municipal sewage effluent (1984)

The virucidal efficacy of peracetic acid (PAA) was evaluated against poliovirus 1, echovirus 1, coxsackievirus B5, human rotavirus, simian rotavirus SA11 and bacteriophage f2 in a municipal sewage effluent. The results indicated relatively high concentrations of acid were required to achieve significant inactivation. Human rotavirus, which was the most resistant, required 140 ppm to achieve 99.99% inactivation. On the other hand, simian rotavirus SA11, which was the most sensitive, required only 20 ppm to achieve the same degree of inactivation. The three enteroviruses reacted similarly and the bacteriophage was slightly less resistant than the enteroviruses, especially at high concentrations of peracetic acid. The effluent did not exert a demand for peracetic acid. Temperature, organic matter and suspended solids had negligible effects on the virucidal efficacy of peracetic acid.
