Observations of Vortex Rossby Waves Associated with a Mesoscale Cyclone

Abstract Short-wavelength (L ∼ 100 km) Rossby waves with an eastward zonal phase velocity were observed by high-frequency radio Doppler current meters and moored ADCPs west of Oahu, Hawaii, during spring 2003. They had Rossby numbers Ro = |ζ/f| = O(1), periods of 12–15 days, and phase speeds of 8–9 cm s−1, and they were surface trapped with vertical e-folding scales of 30–170 m. They transferred horizontal kinetic energy to the background flow of a mesoscale cyclone lying 160–190 km west of Oahu, revealed by altimetry. The waves approximately satisfied the dispersion relation of vortex Rossby waves propagating through the radial gradient of potential vorticity associated with the cyclone. Vertical shear of the background currents may also affect wave propagation. Theoretical studies have shown that vortex Rossby waves provide a mechanism by which perturbed vortices axisymmetrize and strengthen and may be important to the dynamics of oceanic vortices.

Positive solutions of the system of operator equations $A_1X=C_1,XA_2=C_2, A_3XA^*_3=C_3, A_4XA^*_4=C_4$ in Hilbert $C^*$-modules

Necessary and sufficient conditions are given for the operator system $A_1X=C_1$, $XA_2=C_2$, $A_3XA^*_3=C_3$, and $A_4XA^*_4=C_4$ to have a common positive solution, where $A_i$'s and $C_i$'s are adjointable operators on Hilbert $C^*$-modules. This corrects a published result by removing some gaps in its proof. Finally, a technical example is given to show that the proposed investigation in the setting of Hilbert $C^*$-modules is different from that of Hilbert spaces.
High-pressure elasticity of calcium oxide : A comparison between Brillouin spectroscopy and radial X-ray diffraction

Single-crystal Brillouin scattering to 25.2 GPa and powder X-ray diffraction to 65.2 GPa in a radial geometry were carried out on CaO (lime) at ambient temperature in a diamond cell. From Brillouin scattering measurements the isentropic elastic constants of CaO at ambient conditions are C {sub 11} = 219.4 (7), C {sub 12} = 58.1 (7), C {sub 44} = 80.0 (2) GPa, where the numbers in parentheses are 1{sigma} uncertainties on the last digit. The pressure derivatives of the compressional and off-diagonal constants at ambient pressure are {partial_derivative}C {sub 11}/{partial_derivative}P = 9.9 (1), {partial_derivative}C{sub 12}/{partial_derivative}P = 2.2 (1), respectively. The pressure derivative of the shear constant is {partial_derivative}C {sub 44}/{partial_derivative}P = 0.25 (3), and it becomes negative at pressures above 5.9 GPa. Aggregate bulk and shear moduli are K{sub S0} = 112.0 (2) and G{sub 0} = 80.05 (9) GPa, and their pressure derivatives are 4.72 (6) and 1.69 (5), respectively. The radial X-ray diffraction data allow us to estimate the yield strength and the elastic constants of CaO using a phenomenological lattice strain model. The calculated strength of CaO increases from 0.3 to 1.9 GPa in the pressure range between 5.6 and 57.8 GPa. The estimated elastic constantsmore » are in good agreement with the extrapolation of the Brillouin data up to 36.6 GPa. At higher pressures, C {sub 11} appears softer and C{sub 12} appears stiffer than the extrapolation of Brillouin results. The value of C 44 from radial diffraction is in agreement with the Brillouin data through the entire experimental pressure range. The discrepancies between Brillouin and radial diffraction data for C{sub 11} and C{sub 12} can be reconciled if {alpha}, the parameter which describes degree of stress/strain continuity across the sample's grains boundary, is allowed to vary from 1 at 36.6 GPa to 0.82 at 65.2 GPa. The 'hydrostatic' cell volumes determined by applying lattice strain theory were fitted to the third-order Birch-Murnaghan equation. The fitted bulk modulus and its pressure derivative are K{sub T0} = 110 (5) GPa and ({partial_derivative}K{sub T} /{partial_derivative}P){sub T0} = 4.5 (4), consistent with the Brillouin results, although possible softening of the equation of state at high pressure has been identified. The general agreement between the results of the two methods indicates that radial diffraction with lattice strain theory is a valid probe of the mechanical properties of a moderately soft cubic solid as CaO at ultrahigh pressures. However, more tests are required to quantify the effect of plasticity and texturing on the results of this method. « less
STUDENTS ’ LEARNING STYLE AND THEIR ACADEMIC ACHIEVEMENT FOR TAXATION COURSE – A COMPARISON STUDY Too

This paper asserts to determine if there is any difference in the students’ learning style for subjects with different assessment orientation (theoretical versus computational) and if there is any association between students’ learning style and their academic performance in two final year subjects, with and without controlling for their previous academic achievement. Kolb’s (1976) Learning Style Inventory (LSI) was used to gauge the learning style of the final year accounting students of an institute of higher learning. The students were required to complete two sets of LSI questionnaires in relation to two final year subjects with different final assessment orientation, such as Malaysian Taxation which is mainly computational oriented and Financial Strategy which is mainly theoretical oriented. The students’ final examination results for both subjects were extracted for study of its association with their learning style. Students’ learning style is “Converger” dominant for Malaysian Taxation subject, but it’s “Accomodator” dominant for Financial Strategy subject. As such, there is a difference between learning style for subjects with different assessment orientation. However, there is no significant association between the students’ learning style and their academic performance, with or without controlling for their previous academic achievement. Future research could consider combining learning style with some other factors, such as study strategy, and test their association with the academic performance.
Research A New Method for Constructing Confidence Intervals for the Index C pm

In the statistical literature on the study of the capability of processes through the use of indices, Cpm appears to have been one of the most widely used capability indices and its estimation has attracted much interest. In this article, a new method for constructing approximate confidence intervals or lower confidence limits for this index is suggested. The method is based on an approximation of the non-central chisquare distribution, which was proposed by Pearson. Its coverage appears to be more satisfactory compared with that achieved by any of the two most widely used methods thatwere proposedby Boyles, insituations where one isinterested in assessing a lower confidence limit for Cpm. This is supported by the results of an extensive simulation study. Copyright c � 2004 John Wiley & Sons, Ltd.
Enabling self organisation for future cellular networks.

The rapid growth in mobile communications due to the exponential demand for wireless access is causing the distribution and maintenance of cellular networks to become more complex, expensive and time consuming. Lately, extensive research and standardisation work has been focused on the novel paradigm of self-organising network (SON). SON is an automated technology that allows the planning, deployment, operation, optimisation and healing of the network to become faster and easier by reducing the human involvement in network operational tasks, while optimising the network coverage, capacity and quality of service. However, these SON autonomous features cannot be achieved with the current drive test coverage assessment approach due to its lack of automaticity which results in huge delays and cost. Minimization of drive test (MDT) has recently been standardized by 3GPP as a key self- organising network (SON) feature. MDT allows coverage to be estimated at the base station using user equipment (UE) measurement reports with the objective to eliminate the need for drive tests. However, most MDT based coverage estimation methods recently proposed in literature assume that UE position is known at the base station with 100% accuracy, an assumption that does not hold in reality. In this work, we develop a novel and accurate analytical model that allows the quantification of error in MDT based autonomous coverage estimation (ACE) as a function of error in UE as well as base station (user deployed cell) positioning. We first consider a circular cell with an omnidirectional antenna and then we use a three-sectored cell and see how the system is going to be affected by the UE and the base station (user deployed cell) geographical location information errors. Our model also allows characterization of error in ACE as function of standard deviation of shadowing in addition to the path-loss.
Quality Assessment methods for Ginger (Zingiber officinale): A review

The rhizome of ginger (Zingiber officinale Roscoe) is a commonly used edible vegetable, condiment, and spice that are used worldwide for culinary, nutritional, medicinal and industrial purposes. Its great medicinal and economical value provide a great possibility for contamination and adulteration. Closely related species are usually used mistakenly as ginger and are hardly differentiated. A proper method of quality control is required for its authentication and analysis. This review discusses various techniques employed for the quality control of ginger including different chromatographic and spectroscopic methods, DNA profiling in addition to the application of multivariate analysis. The advantages and drawbacks of each method are presented as well as recommendations for improved quality assessment.
The Role of Topographically Induced Vortices in Tropical Cyclone Formation over the Indian Ocean

AbstractThe role of Sumatra and adjacent topographic features in tropical cyclone (TC) formation over the Indian Ocean (IO) is investigated. Sumatra, as well as the Malay Peninsula and Java, have mountainous terrain that partially blocks low-level flow under typical environmental stratification. For easterly low-level flow, these terrain features often produce lee vortices, some of which subsequently shed and move westward from the northern and southern tips of Sumatra and thence downstream over the IO. Since Sumatra straddles the equator, extending in a northwest–southeast direction from approximately 6°N to 6°S, the lee vortices, while counter-rotating, are both cyclonic. Hence, they can serve as initial disturbances that eventually contribute to TC formation over the IO. In addition, low-level, equatorial westerly flow impinging on Sumatra is also typically blocked and diverges, at times contributing to cyclonic circulations over the IO, primarily near the southern end of the island.Data from two recen.
FRB 121102 Is Coincident with a Star-forming Region in Its Host Galaxy

We present optical, near-infrared, and mid-infrared imaging of the host galaxy of FRB 121102 with the Gemini North telescope, the Hubble Space Telescope, and the Spitzer Space Telescope. The FRB 121102 host galaxy is resolved, revealing a bright star-forming region located in the outskirts of the irregular, low-metallicity dwarf galaxy. The star-forming region has a half-light radius of 0.68 kpc ( ), encompassing the projected location of the compact ( pc), persistent radio source that is associated with FRB 121102. The half-light diameter of the dwarf galaxy is 5–7 kpc, and broadband spectral energy distribution fitting indicates that it has a total stellar mass of . The properties of the host galaxy of FRB 121102 are comparable to those of extreme emission line galaxies, also known as hosts to some hydrogen-poor superluminous supernovae and long-duration γ-ray bursts. The projected location of FRB 121102 within the star-forming region supports the proposed connection of FRBs with newly born neutron stars or magnetars.
The Evolution of Income and Fertility Inequalities over the Course of Economic Development: A Human Capital Perspective

Using an endogenous‐growth, overlapping‐generations framework in which human capital is the engine of growth, we trace the dynamic evolution of income and fertility distributions and their interdependencies over three endogenous phases of economic development. In our model, heterogeneous families determine fertility and children’s human capital, and generations are linked via parental altruism and social interactions. We derive and test discriminating propositions concerning the dynamic behavior of inequalities in fertility, educational attainments, and three endogenous income inequality measures—family‐income inequality, income‐group inequality, and the Gini coefficient. In this context, we also reexamine the “Kuznets hypothesis” concerning the relation between income growth and inequality.
N / AlN / GaNon-SiC Microwave HEMTs CNF Project # 370-89 Principal Investigator ( s ) :

In order to maintain effective gate modulation and mitigate short channel effects, when reducing gate length, it is necessary to simultaneously reduce the barrier thickness [3]. To maintain a desirable current density, on the order of 1 A/mm, a thinned barrier dictates an increase in aluminum (Al) composition. Engineered high-Al composition AlxIn1-xN barriers provide higher polarization induced sheet charge with lower strain than achievable using traditional AlxGa1-xN barrier layers. In this work, the performance of AlxIn1-xN/AlN/GaN-on-SiC HEMTs is investigated.
Hysteresis and the NAIRU in the Euro Area

This paper analyses the Nairu in the Euro Area and the influence that hysteresis had on its development. Using the Kalman-filter technique we find that the Nairu has varied considerably since the early seventies. The Kalman-filter technique is applied here using explicit exogenous variables. In order to test for hysteresis, the dependence of the Nairu on actual unemployment and long-term unemployment is estimated and found to be significant for the Euro Area and Germany respectively. The existence of hysteresis effects implies the possibility of a long-run non-superneutrality of monetary policy.
The Expression of p53 and Survival of Extranodal NK/T-Cell Lymphoma, Nasal Type (ENKL) in Thai Patients

Objective: To determine the association between p53 expression and disease parameters, treatment responses, and survival of Thai patients with extranodal NK/T-cell lymphoma, nasal type (ENKL). Materials and Methods: Adult patients with ENKL at Songklanagarind Hospital from 2001 to 2012 were reviewed. Clinical parameters and outcome data were extracted. The available pathological specimens were immunochemically stained for p53. The results were analyzed for association with disease stage, prognostic scores, treatment responses, and overall survival. Results: Twenty-four patients (17 males and 7 females) were included for the study. The median age was 52 years. Most patients were under 60 years old (71%), had ECOG scores 0-1 (92%), stage I-II (92%), low to low-intermediate International Prognostic Index (IPI) (92%), and low Prognostic Index for PTCL, NOS (79%). All patients presented with extranodal lesions, most commonly nasal lesions (83%). Seventy percent of patients were treated with chemotherapy, predominantly (94%) CHOP regimen and 54% percent with radiotherapy, alone or as concurrent chemo-radiation. Of 18 evaluable patients, the overall response rate was 67%, with 56% complete response. The p53 expression is detected in 92% of tumors and significantly correlated with limited stage and low IPI. The median overall survival (OS) was 16.8 months. Advanced stage, high IPI, radiotherapy, and response to treatment, but not p53 expression, are associated with lower OS. With Cox regression analysis, radiotherapy and response to treatment were independent prognostic predictors for survival. Conclusion: p53 is commonly expressed in ENKL and significantly associated with limited stage and low IPI. Radiotherapy and response to treatment were predictors for survival.
Detecting features in the dark energy equation of state: a wavelet approach

We study the utility of wavelets for detecting the redshift evolution of the dark energy equation of state w(z) from the combination of supernovae (SNe), CMB and BAO data. We show that local features in w, such as bumps, can be detected efficiently using wavelets. To demonstrate, we first generate a mock supernovae data sample for a SNAP-like survey with a bump feature in w(z) hidden in, then successfully discover it by performing a blind wavelet analysis. We also apply our method to analyze the recently released ``Constitution'' SNe data, combined with WMAP and BAO from SDSS, and find weak hints of dark energy dynamics. Namely, we find that models with w(z) < −1 for 0.2 < z < 0.5, and w(z) > −1 for 0.5 < z < 1, are mildly favored at 95% confidence level. This is in good agreement with several recent studies using other methods, such as redshift binning with principal component analysis (PCA) (e.g. Zhao and Zhang, arXiv: 0908.1568).
Influence of Resin Content and Density on Thickness Swelling of Three-layered Hybrid Particleboard Composed of Sawdust and Acacia mangium

This study was carried out to determine the thickness swelling of three-layered hybrid particleboard composed of sawdust and Acacia mangium under two different testing conditions. The experimental particleboards, composed of mixed sawdust and Acacia mangium, were fabricated with different resin contents and densities within the face and back (both composed of sawdust) and the core (composed of Acacia mangium particles). Particleboards consisting of only Acacia mangium particles were used as the control. Three different resin ratios (8:10:8, 10:10:10, and 12:10:12) were tested in combination with three different board densities (500, 600, and 700 kg/m3). Urea formaldehyde (UF), with the addition of wax, was used as a binder. The thickness swelling was evaluated using two tests: water immersion, and change in relative humidity, specifically between 10 and 90%, in accordance with the ASTM D 3502-76 (ASTM 1999) standard. The results indicated that there were significant interactions between the resin contents and the densities, which had an impact on the percentage of thickness swelling of the mixed sawdust-Acacia mangium composites in both test conditions.
Sublethal effect of Abamectin in the functional response of the predator Phytoseiulus persimilis ( Athias-Henriot ) on Tetranychus urticae ( Koch ) ( Acari : Phytoseiidae , Tetranychidae )

The biological control used for the control of Tetranychus urticae (Koch) is the predator mite Phytoseiulus persimilis (Athias-Henriot). It is important to the know the effects of acaricides on the biological behavior the Abamectin on the functional response of P. persimilis. The functional response of the predator was of type II exposed to concentration of Abamectin, the functional response parameters: successful attack rate (a’), handling time (Th), search efficiency and the maximum predation theory (T/Th) were affected by the acaricide. The predator spends more time in persecute, dominate, consume and prepair it self to the next searching comparing with the proof subject an the predation ability was affected.
Are there indications of climate change induced increases in variability of major field crops in the northernmost European conditions

As the northern hemisphere will experience the greatest increases in temperature and indications of climatic change are already visible in the north (in the 2000s average temperatures exceeded the long-term mean), we sought to establish if there are already signs of increased variability in yield and quality of the major field crops grown under the northernmost European growing conditions: spring and winter cereals (barley Hordeum vulgare L., oat Avena sativa L., wheat Triticum aestivum L., rye Secale cereale L.), spring rapeseed (turnip rape Brassica rapa L., oilseed rape B. napus L.), pea (Pisum sativum L.) and potato (Solanum tuberosum L.). We used long-term yield datasets of FAO for Finland (1960s to date) and MTT Agrifood Research Finland (MTT) Official Variety Trial datasets on yield and quality of major field crops in Finland since the 1970s. Yield variability was exceptionally high in the 1980s and 1990s, but previously and subsequently national yields were clearly more stable. No progressive increase in yield variability was recorded. No marked and systematic changes in variability of quality traits were recorded, except for rapeseed, which exhibited reduced variability in seed chlorophyll content. This may at least partly attribute to the differences in intensity of input use and thereby responsiveness of the crops before and after 1980 and 1990 decades. We also noted that in the 2000s average temperatures were higher than in earlier decades and this was the case for all months of the growing season except June, which represents, however, the most critical phase for yield determination in most of the field crops in Finland. Also in the 2000s precipitation increased in the first three months of the growing season and thereafter decreased, but without signs of significantly increased numbers of heavy showers (extreme rain events). Hence, in general constant, increased average temperatures during the growing seasons of the 2000s were identified, but with reduced yield variability, which was partly attributable to the diminished use of inputs, especially fertilisers.
Extranodular growth of Frankia on Casuarina equisetifolia

17 genera of non-leguminous angiosperms bear NI-fixing root nodules initiated by an actinomycete known as Frankia [1,11]. The expanding volume of current literature attests to the significance vested in this symbiosis. However, to the best of our knowledge, no publications up to this point have dealt with the occurrence and behaviour of Frankia outside its specific niche, the nodule. Reported here are observations indicating that Frankia is able to grow outside the nodule of Casuarina equisetifolia and to proliferate in its vicinity. Our study is focused on Casuarina because these tropical and subtropical non-legumes play a major role by virtue of their ability to thrive on nitrogen-deficient soils.
