A new algorithm for the computation of the decimals of the inverse

Ancient mathematical formulae can be directly applied to the optimization of the algebraic computation. A new algorithm used to compute decimals of the inverse based on such ancient mathematics is reported in this paper. Sahayaks (auxiliary fraction) sutra has been used for the hardware implementation of the decimals of the inverse. On account of the ancient formulae, reciprocal approximation of numbers can generate on the y" either the rst exact n decimal of inverse, n being either arbitrary large or at least  6 in almost all cases. The reported algorithm has been implemented, and functionality has been checked in T-Spice. Performance parameters, like propagation delay and dynamic switching power consumptions, are calculated through spice-spectre of 90 nm CMOS technology. The propagation delay of the resulting 4-digit reciprocal approximation algorithm was only  1:8 uS and consumed  24:7 mW power. The implementation methodology off ered substantial reduction of propagation delay and dynamic switching power consumption from its counterpart (NR) based implementation.
Quantitative Trait Locus Mapping and Candidate Gene Analysis for Functional Stay-Green Trait in Rice

Functional stay-green (FSG) delays leaf yellowing, maintaining photosynthetic competence, whereas nonfunctional stay-green (NFSG) retains only leaf greenness without sustaining photosynthetic activity. Retention of chlorophylls and photosynthetic capacity is important for increasing crop yield. We determined the main-effect quantitative trait loci (QTLs) for FSG traits in the japonica rice SNU-SG1 and isolated candidate genes. To identify QTLs influencing FSG, we analyzed eight traits: (1) 1 day after heading-degree of chlorophyll content of flag leaf, (2) 1 day after heading-degree of chlorophyll content of second leaf, (3) 1 day after heading-degree of chlorophyll content of flag and second leaves, (4) 50 day after heading-degree of chlorophyll content of flag leaf, (5) 50 day after heading-degree of chlorophyll content of second leaf, (6) 50 day after heading-degree of chlorophyll content of flag and second leaves, (7) relative decline degree of chlorophyll content of flag and second leaves, and (8) flowering time. We carried out QTL analysis with F7 RIL from a cross of japonica rice ‘SNU-SG1’ and indica rice ‘Milyang23 (M23)’. Using 131 molecular markers, we identified 18 QTLs for the eight traits with a threshold LOD value > 2.8. Sequence analysis identified 16 candidate genes for 10 main-effect QTLs. Of these, we have chosen seven strong candidate genes for the 10 main-effect QTLs. These genetic resources will be useful for breeding high-yielding rice cultivars.
Reasoning on transition from manipulative strategies to general procedures in solving counting problems

We describe the procedures used by 11- to 12-year-old students for solving basic counting problems in order to analyse the transition from manipulative strategies involving direct counting to the use of the multiplication principle as a general procedure in combinatorial problems. In this transition, the students sometimes spontaneously use tree diagrams and sometimes use numerical thinking strategies. We relate the findings of our research to recent research on the representational formats on the learning of combinatorics, and reflect on the didactic implications of these investigations.
Embedding Science Facts in Leisure Skill Instruction Conducted by Peer Tutors

This investigation evaluated the effectiveness of using peer tutors to teach a chained leisure skill (i.e., UNO card game) to three middle school students with disabilities using a simultaneous prompting procedure within a multiple probe design. The investigation also assessed whether the students with disabilities would acquire four unrelated science core content facts presented as nontargeted information during instructive feedback. Results indicated that all students met or made progress toward criterion on the leisure skill. In addition, two of the three students acquired all four core content facts.
Frequency of hepatitis C in patients with rheumatoid arthritis

Background: Hepatitis C virus (HCV) infection has been explained as a disease that sometimes present with rheumatic manifestations indistinguishable from rheumatoid arthritis. This study has been performed to evaluate the frequency of hepatitis C virus infection in a group of patients with rheumatoid arthritis. Patients and methods: In this study, during one year, serum samples collected from two hundred consecutive patients with rheumatoid arthritis in all affiliated hospitals of Shaheed Beheshti University, M.C. , were examined for anti-HCV antibody and HCV-RNA by ELISA and RT-PCR method, respectively. Using a questionnaire, the frequency of HCV infection, age and sex distribution, duration of rheumatoid arthritis, associated immune mediated disorders and risk factors for hepatitis C virus infection were assessed. Results: A total of 200 patients (M/F=26/174) who were mainly aged 51-70 years were studied. The frequency of HCV was found to be 2% (95%CI: 0.6-7%). All of the infected persons have had a low risk occupation in terms of exposure to the virus and none of them had HCV risk factors. No associated immune mediated disorder was found in HCV infected patients. Conclusion: Our results did not support any contribution of HCV infection in the pathogenesis of rheumatoid arthritis.
Human Capital - Driving Forse of Intelectual Capital in Creating Future

In time characterized by complex and uncertain business environment and working conditions; where small, medium but even large (and up till yesterday) successful companies are failing on daily basis, it is important to have economy models which will ensure reestablishment of value system of industrial era, models which will give expected, positive, results. In general, this is not the case since there is no compatibility of models with requirements of information era. So, those negative results together with market positions taken by those who understand changes better, emphasises need for understanding and implementing change management in companies. When trying to overcome mentioned obstacles in coping with changes and demolished value system, key success variable was detected – human capital as the best source of creative energy. In this study, human capital, as in many studies before, is recognised as driving force of intellectual capital and as well as synergy effect of conatival, motivational, cognitional, social, moral and communicational dimension.
A new method for measuring deformation on volcanoes and other natural terrains using InSAR persistent scatterers

We present here a new InSAR persistent scatterer (PS) method for analyzing episodic crustal deformation in non‐urban environments, with application to volcanic settings. Our method for identifying PS pixels in a series of interferograms is based primarily on phase characteristics and finds low‐amplitude pixels with phase stability that are not identified by the existing amplitude‐based algorithm. Our method also uses the spatial correlation of the phases rather than a well‐defined phase history so that we can observe temporally‐variable processes, e.g., volcanic deformation. The algorithm involves removing the residual topographic component of flattened interferogram phase for each PS, then unwrapping the PS phases both spatially and temporally. Our method finds scatterers with stable phase characteristics independent of amplitudes associated with man‐made objects, and is applicable to areas where conventional InSAR fails due to complete decorrelation of the majority of scatterers, yet a few stable scatterers are present.
Field-based measurements of oxygen uptake and swimming performance with adult Pacific salmon using a mobile respirometer swim tunnel

Novel field measurements of critical swimming speed (Ucrit) and oxygen uptake (Mo2) in three species of adult Pacific salmon Oncorhynchus spp. up to 3� 5 kg in body mass were made using two newly designed, mobile Brett-type swim tunnel respirometers sited at a number of field locations in British Columbia, Canada. Measurements of Ucrit, which ranged from 1� 68 to 2� 17 body lengths s � 1 ,an d ma ximumMo2, which ranged from 8� 74 to 12� 63 mg O2 kg � 1 min � 1 depending on the species and field location, were judged to be of similar quality when compared with available data for laboratory-based studies. Therefore high quality respirometry studies were possible in the field using adult wild swimming salmonids. In addition, the recovery of wild adult Pacific salmon from the exhaustive Ucrit swim test was sufficiently rapid that swimming performance could be repeated with <1h of recovery time between the termination of the initial swim test and the start of the second test. Moreover, this repeat swimming performance was possible without routine Mo2 being reestablished. This result suggests that wild adult salmon are capable of carrying a moderate excess post-exercise oxygen consumption without adversely affecting Ucrit ,m a ximumMo2 or swimming economy. Such capabilities may be extremely important for timely migratory passages when salmonids face repetitive hydraulic challenges on their upstream migration.
A Rapid Colorimetric Method for Epicuticular Wax Contest of Sorghum Leaves 1

Epicuticular wax deposition on sorghum [(Sorghum bicolor)L. Moenchl leaf blades imparts drought resist . ante. Screening of a large number of sorghum genotypes for increased leaf epicuticular wax content, utilizing the available gravimetric method, is ! practical. A more rapid colorimetric method was developed and evaluated against the current gra metric method . The colorimetric method is based on the color change produced due to the reaction of wax with acidic K 0Cr,. O, reagent . Wax content determined by the colorimetric method was highly correlated (r = 0 .984) with that determined by the grain metric method. Leaf epicuticular wax content in 11 fieldgrown grain sorghum cultivars did not vat) between growth stage #4 (tip of flag leaf showing) and (soft dough), at which stages comparable wax readings were obtained among the four top leaf blades . A CK 60 'bloom less' (bmbm) genotype had only half of the epicuticular content of the CK 60 'normal' (BmBm) genotype. Ten cultivars, all of the BmBm genotype, significantly differed in epiculticular wax content, ranging from 1 . 14 to 1.99 (SE = 0.00(i)mg/dm of leaf.
Optimal Taxation of Risky Human Capital

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital. Education subsidies are not used for social insurance, but are only targeted at off-setting the distortions of the labor tax and internalizing a fiscal externality. Both optimal education subsidies and tax rates increase if labor and education are more complementary, since education subsidies indirectly lower labor tax distortions by stimulating labor supply. Optimal education subsidies (taxes) also correct non-tax distortions arising from missing insurance markets. Education subsidies internalize a positive (negative) fiscal externality if there is underinvestment (overinvestment) in education due to risk. Education policy unambiguously allows for more social insurance if education is a risky activity. However, if education hedges against labor market risk, optimal tax rates could be lower than without education subsidies.
Correlative analysis of the expression of IL-10 and Ki-67 in human cervical cancer and cervical intraepithelial neoplasias and human papillomavirus infection

This study investigated the expression of IL-10 and Ki-67 in human cervical cancer and cervical intraepithelial neoplasia (CIN) and the correlation with human papillomavirus infection. A total of 110 patients with cervical lesions undergoing surgical treatment in Shanghai First Maternity and Infant Hospital, Tongji University School of Medicine from 2016 to 2017 were selected. Those patients included 36 cases of cervical cancer and 74 cases of CIN. At the same time, 30 cases of chronic cervicitis were selected as the control group. RT-qPCR was used to detect the expression of IL-10 and Ki-67 in cervical tissue. PCR was used to detect HPV infection in cervical tissue. The expression levels of IL-10 and Ki-67 in the cervical cancer and CIN groups were higher than those in the control group. Moreover, the expression levels of IL-10 and Ki-67 in the cervical cancer and CIN II–III groups were higher than those in the CIN I group (P<0.05). In addition, the expression levels of IL-10 and Ki-67 in the cervical cancer group were significantly higher than those in the CIN II–III group. Furthermore, the expression levels of IL-10 and Ki-67 were positively correlated with HPV infection (r=0.783 or 0.712, P<0.05). Finally, the expression levels of IL-10 and Ki-67, and HPV infection in the cervical lesions studied were significantly different. Therefore, combined detection of IL-10, Ki-67 and HPV infection can improve the diagnosis of CIN and early cervical cancer.
Preventing Irrigation Furrow Erosion with Small Applications of Polymers

Soil erosion is a serious problem threatening sustainability of agriculture globally and contaminating surface waters. The objective of this study was to determine whether low concentrations of anionic polymers in irrigation water would appreciably reduce irrigation furrow erosion on Portneuf silt loam (coarse-silty, mixed, mesic Durixerollic Calciorthid), a highly erodible soil. Furrow slope was 1.6%, furrow length was 175 m, and irrigation rates ranged from 15 to 23 L min-'. Inflow during the first 1 to 2 h of the first 8-h irrigation was treated. Subsequent irrigations were untreated. Polyacrylamide (PAM) or starch copolymer solutions were injected into irrigation water entering furrows at concentrations of 0, 5, 10, and 20 g m- 3. Sediment loss from polymer-treated furrows was significantly less than that of control furrows in the first (treated) and second (untreated) irrigations, but not in the fourth (untreated). The PAM provided better erosion control than the starch copolymer. Efficacy of PAM treatments varied depending on its concentration, duration of furrow exposure, and water flow rate. In the initial (treated) irrigation and at low flow rates, 10 g III -3 PAM reduced mean sediment load by 97% compared with untreated furrows. Residual erosion abatement in a subsequent irrigation, without further addition of PAM, was approximately 50%. The PAM increased net infiltration and promoted greater lateral infiltration. Effective erosion control was achievable for a material cost below $3 ha-' irrigation-'.
Sudden Arrhythmic Death: Family Evaluation Identifies the Cause

A 23-year-old female professional dancer died suddenly following physical activity. Routine postmortem examination failed to establish the cause of death. No cardiac structural abnormalities were revealed. She had a history of presyncopal episodes during the last two months preceding her sudden cardiac death (SCD). Following the proband’s death, her family was referred to our department for clinical evaluation. Following informed consent, family members were evaluated with a standard protocol. All individuals underwent detailed non-invasive evaluation followed by genetic testing. The proband’s uncle was the first family member to undergo clinical investigation. He had been diagnosed with arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) almost 5 years before his niece’s SCD. The proband was positive for a plakophilin-2 (PKP2) mutation and both her father and uncle had a typical form of the ARVC/D disease. To strengthen our diagnostic assessment an immunohistochemical analysis was undertaken of a myocardial sample obtained at autopsy, which pointed towards ARVC. Thus, her death was attributed to ARVC. Probably, the mutation had been inherited from her paternal grandfather. Although he had never been clinically evaluated, and no tissue was available for genetic analysis, he had a history of SCD at the age of 72, thus, raising suspicions of cardiac disease
Chromospheric activity on the RS CVn-type binary UX Arietis

High resolution spectroscopic observations of UX Ari made during three observing seasons in 2000 have been analyzed by means of the spectral subtraction technique. The information about chromospheric activity of UX Ari has been obtained from several optical chromospheric activity indicators such as the Hei D-3, Nai D-1, D-2, H-alpha, and CaII IRT lines. The results suggest the chromospheric activity of the system is associated with the cooler secondary. An orbital phase modulation of chromospheric emissions is found, and consequently the activity longitude area of the system is obtained, that corresponds to the phase interval near the second quadrature of the binary system. A are-like event is detected during our new observations, characterized by the dramatic increase in the Halpha and CaII IRT emission lines, that is confirmed by the emission of the Hei D-3 line and the filled-in cores of the Nai D-1, D-2 lines. It is found that the values of the EW8542/EW8498 ratio decrease when the activity of the system increases, especially when the are occurs. The small values of the EW8542/EW8498 ratio indicate that the CaII IRT emissions come from plage-like regions. The high activity level of UX Ari around the quadrature may originate with the coupling between the chromospheric activity of the secondary and the mass transfer activity of the two components.
Forest soil carbon stock estimates in a nationwide inventory: evaluating performance of the ROMULv and Yasso07 models in Finland

Abstract. Dynamic soil models are needed for estimating impact of weather and climate change on soil carbon stocks and fluxes. Here, we evaluate performance of Yasso07 and ROMULv models against forest soil carbon stock measurements. More specifically, we ask if litter quantity, litter quality and weather data are sufficient drivers for soil carbon stock estimation. We also test whether inclusion of soil water holding capacity improves reliability of modelled soil carbon stock estimates. Litter input of trees was estimated from stem volume maps provided by the National Forest Inventory, while understorey vegetation was estimated using new biomass models. The litter production rates of trees were based on earlier research, while for understorey biomass they were estimated from measured data. We applied Yasso07 and ROMULv models across Finland and ran those models into steady state; thereafter, measured soil carbon stocks were compared with model estimates. We found that the role of understorey litter input was underestimated when the Yasso07 model was parameterised, especially in northern Finland. We also found that the inclusion of soil water holding capacity in the ROMULv model improved predictions, especially in southern Finland. Our simulations and measurements show that models using only litter quality, litter quantity and weather data underestimate soil carbon stock in southern Finland, and this underestimation is due to omission of the impact of droughts to the decomposition of organic layers. Our results also imply that the ecosystem modelling community and greenhouse gas inventories should improve understorey litter estimation in the northern latitudes.
Highly Variable Latest Pleistocene‐Holocene Incremental Slip Rates on the Awatere Fault at Saxton River, South Island, New Zealand, Revealed by Lidar Mapping and Luminescence Dating

Geomorphic mapping using high‐resolution lidar imagery and luminescence dating reveal highly variable incremental Holocene‐latest Pleistocene slip rates at the well‐known Saxton River site along the Awatere fault, a dextral strike‐slip fault in the Marlborough Fault System, South Island, New Zealand. Using lidar and field observations, we measured seven fault offsets recorded by fluvial terraces and bedrock markers. Improved dating of the offsets is provided by post‐IR‐IRSL225 luminescence ages. Incremental slip rates varied from <2 mm/yr to >15 mm/yr over intervals of thousands of years and tens of meters of slip, demonstrating order‐of‐magnitude temporal variations in rate at a single site. These observations have basic implications for earthquake fault behavior, lithospheric mechanics, discrepancies between geodetic and geologic slip rates, and probabilistic seismic hazard assessment.
