description: Tetranychus lombardinii Baker & Pritchard, 1960
Aedeagus curves dorsad, forming a knob about one fourth to one fifth length of dorsal margin of shaft; knob and shaft axes almost parallel; posterior projection small and acute; anterior projection rounded (Figure 5 B) male empodium I with 2 proximoventral spurs and a minute mediodorsal spur; empodium II with 3 pairs of proximoventral hairs and a tiny mediodorsal spur; female striae between third (e1) and fourth (f1) pairs of dorsocentral setae longitudinal, a diamond-shaped figure formed between these setae; dorsal lobes narrow, triangular, mostly taller than broad and well separated at their bases; in some specimens ventral lobes weak or absent but usually low, semicircular, broad and extend from genital opening to near gnathosoma; lobes on prodorsum very broad and hardly more than an occasional incision of striae.
 Specimens examined: Five males and several females collected on Morus sp. (Moraceae) from ICIPE compound, Nairobi (S01°13.140'; E036°53.440').
 Remark: This species has been reported from the Tropics, Australia and Oriental Indian regions. It has a wide host range and occurs as a pest of several agricultural crops (Meyer, 1974). The first record of this species in Kenya was on Spinacia oleraceae (Amaranthaceae) from Ruiru, Thika district (Baker and Pritchard, 1960). It appears uniformly red in colour in the field.

description: We study spin-polarized states and their stability in anti-ferromagnetic states of spinor (F=1) quasi-one-dimensional Bose-Einstein condensates. Using analytical approximations and numerical methods, we find various types of polarized states, including: patterns of the Thomas-Fermi type; structures with a pulse-shape in one component inducing a hole in the other components; states with holes in all three components; and domain walls. A Bogoliubov-de Gennes analysis reveals that families of these states contain intervals of a weak oscillatory instability, except for the domain walls, which are always stable. The development of the instabilities is examined by means of direct numerical simulations.

description: Phishing is the number one threat in the world of internet. Phishing attacks are from decades and with each passing year it is becoming a major problem for internet users as attackers are coming with unique and creative ideas to breach the security. In this paper, different types of phishing and anti-phishing techniques are presented. For this purpose, the Systematic Literature Review(SLR) approach is followed to critically define the proposed research questions. At first 80 articles were extracted from different repositories. These articles were then filtered out using Tollgate Approach to find out different types of phishing and anti-phishing techniques. Research study evaluated that spear phishing, Email Spoofing, Email Manipulation and phone phishing are the most commonly used phishing techniques. On the other hand, according to the SLR, machine learning approaches have the highest accuracy of preventing and detecting phishing attacks among all other anti-phishing approaches.

description: We present a sequence of 12 monthly polarimetric 15, 22, and 43 GHz VLBA observations of the radio galaxy 3C 120 revealing a systematic presence of gradients in Faraday rotation and degree of polarization across and along the jet. The degree of polarization increases with distance from the core and toward the jet edges, and has an asymmetric profile in which the northern side of the jet is more highly polarized. The Faraday rotation measure is also stratified across the jet width, with larger values for the southern side. We find a localized region of high Faraday rotation measure superposed on this structure between approximately 3 and 4 mas from the core, with a peak of about 6000 rad/m^2. Interaction of the jet with the external medium or a cloud would explain the confined region of enhanced Faraday rotation, as well as the stratification in degree of polarization and the flaring of superluminal knots when crossing this region. The data are also consistent with a helical field in a two-fluid jet model, consisting of an inner, emitting jet and a sheath containing nonrelativistic electrons. However, this helical magnetic field model cannot by itself explain the localized region of enhanced Faraday rotation. The polarization electric vectors, predominantly perpendicular to the jet axis once corrected for Faraday rotation, require a dominant component parallel to the jet axis (in the frame of the emitting plasma) for the magnetic field in the emitting region.

description: This study combines block-recursive restrictions with non-Gaussian and mean independent shocks to derive identifying and overidentifying higher-order moment conditions for structural vector autoregressions. We show that overidentifying higher-order moments can contain additional information and increase the efficiency of the estimation. In particular, we prove that in the non-Gaussian recursive SVAR higher-order moment conditions are relevant and therefore, the frequently applied estimator based on the Cholesky decomposition is inefficient. Even though incorporating information in valid higher-order moments is asymptotically efficient, including many redundant and potentially even invalid moment conditions renders standard SVAR GMM estimators unreliable in finite samples. We apply a LASSO-type GMM estimator to select the relevant and valid higher-order moment conditions, increasing finite sample precision. A Monte Carlo experiment and an application to quarterly U.S. data illustrate the improved performance of the proposed estimator.

The suburban water balance : daily, monthly and annual results from Vancouver, B.C.
Creators: name: Grimmond, Christine Susan Betham
Publisher: name: University of British Columbia
Year: 2010

description: This study presents a method for the assessment of the daily water balance at a suburban site. It is applied to a suburb of south central Vancouver, B.C. for the year 1982. Precipitation and piped water supply were measured. Evaporation was calculated using a model developed by Oke and Steyn (pers. comm.) which utilises measured climatological data. Runoff was determined for pervious and impervious surface types using assumptions related to soil retention, infiltration and storage capacity. The net change in water storage was calculated by difference. Sensitivity analyses were conducted on the input values in order to determine their impact on the model output. The appropriate range for input values was determined from analyses of their variability. Results indicate that the objective of a water balance study is important in determining how carefully the catchment describing parameters should be defined. For instance, if the purpose of the study is to determine the daily water balance only, and not the daily moisture status of the suburban environment, then the definition of the parameters may be less rigorous. The results show that the summer water balance of the suburban environment is modified to a considerable extent by the amount of water piped in and applied to the external environment. In the Vancouver study area the piped supply is equal to the input of precipitation. Summer water use by the residents is found to be related to air temperature and the occurrence of precipitation. The daily water balances included days when the amount of water being added to the external environment is sufficient not only to support the calculated evaporation but also to add to storage. The primary means of water output from the system in the summer months was evaporation, which represented 81% of the water loss. The calculated results compared favourably with previous research within the Vancouver region. Daily water balance results for July and August were similar to those of an earlier pilot study in the area; evaporation rates were similar in magnitude to those reported for a nearby suburban area by Kalanda et al. (1980); and the monthly runoff ratios showed the same pattern as those for a nearby undeveloped catchment.

description: EE Cam is a previously little studied Delta Scuti pulsator with amplitudes between those of the HADS (High-Amplitude Delta Scuti stars) group and the average low-amplitude pulsators. Since the size of stellar rotation determines both which pulsation modes are selected by the star as well as their amplitudes, the star offers a great opportunity to examine the astrophysical connections. Extensive photometric measurements covering several months were carried out. 15 significant pulsation frequencies were extracted. The dominant mode at 4.934 cd$^{-1}$ was identified as a radial mode by examining the phase shifts at different wavelengths. Medium-dispersion spectra yielded a $v\sin i$ value of $40 \pm 3$ km s$^{-1}$. This shows that EE Cam belongs to the important transition region between the HADS and normal Delta Scuti stars.

description: Three-body calculations of $K\bar{K}N$ system with quantum numbers $I=1/2$, $J^π=(\frac{1}{2})^{+}$ were performed. Using separable potentials for two-body interactions, we calculated the $πΣ$ mass spectra for the $(\bar{K}N)_{I=0}+K^{+}\rightarrow(πΣ)^{0}K^{+}$ reaction on the basis of three-body Alt-Grassberger-Sandhas equations in the momentum representation. In this regard, different types of $\bar{K}N-πΣ$ potentials based on phenomenological and chiral SU(3) approach are used. The possibility to observe the trace of $Λ(1405)$ resonance in $(πΣ)^{0}$ mass spectra was studied. Using the $χ^{2}$ fitting, it was shown that the mass of $Λ$(1405) resonance is about 1417 $\mathrm{MeV}/c^{2}$.

description: Der Artikel basiert auf einer Studie des Instituts für Gender and Diversity der Fachhochschule Ostschweiz (FHO), die 2014 und 2015 im Raum Ostschweiz durchgeführt wurde. Die Studie hatte zum Ziel, die Selbstbeschreibung und -wahrnehmung von Mädchen und jungen Frauen sowie deren Interessen und Zukunftsvorstellungen zu untersuchen. Dafür wurden insgesamt 78 leitfadengestützte qualitative Interviews mit Mädchen und jungen Frauen aus drei verschiedenen Altersgruppen und Schulen aus unterschiedlichen sozialen und geografischen Milieus im Hinblick auf ihre (vergeschlechtlichten) Lebensund Selbstkonzepte analysiert. Die Auswertung der Interviews erfolgte inhaltsanalytisch. Die deskriptiv dargestellten Ergebnisse zeigen eine Veränderung von eher offenen Lebensund Selbstkonzepten bei den 6- und 9-Jährigen hin zu eher geschlechtstypischen Vorstellungen bei den 15- bis 16-Jährigen. Im Alter zwischen 10 und 15 Jahren scheinen sich also die ersten Weichen für (oder auch gegen) eine geschlechtstypische Berufswahl und Lebensplanung zu stellen. Viele Mädchen, die durchaus geschlechtsatypische Interessen und Fähigkeiten aufweisen, haben sich letztlich – zumindest in der ersten Ausbildung – für einen frauentypischen Beruf entschieden.

description: We present new high spatial resolution HST/ACS imaging of NGC 1140 and high spectral resolution VLT/UVES spectroscopy of its central star-forming region. The central region contains several clusters, the two brightest of which are clusters 1 and 6 from Hunter, O'Connell & Gallagher, located within star-forming knots A and B, respectively. Nebular analysis indicates that the knots have an LMC-like metallicity of 12 + log(O/H) = 8.29 +/- 0.09. According to continuum subtracted H alpha ACS imaging, cluster 1 dominates the nebular emission of the brighter knot A. Conversely, negligible nebular emission in knot B originates from cluster 6. Evolutionary synthesis modelling implies an age of 5 +/- 1 Myr for cluster 1, from which a photometric mass of (1.1 +/- 0.3) x 10^6 Msun is obtained. For this age and photometric mass, the modelling predicts the presence of ~5900 late O stars within cluster 1. Wolf-Rayet features are observed in knot A, suggesting 550 late-type WN and 200 early-type WC stars. Therefore, N(WR)/N(O) ~ 0.1, assuming that all the WR stars are located within cluster 1. The velocity dispersions of the clusters were measured from constituent red supergiants as sigma ~ 23 +/- 1 km/s for cluster 1 and sigma ~ 26 +/- 1 km/s for cluster 6. Combining sigma with half-light radii of 8 +/- 2 pc and 6.0 +/- 0.2 pc measured from the F625W ACS image implies virial masses of (10 +/- 3) x 10^6 Msun and (9.1 +/- 0.8) x 10^6 Msun for clusters 1 and 6, respectively. The most likely reason for the difference between the dynamical and photometric masses of cluster 1 is that the velocity dispersion of knot A is not due solely to cluster 1, as assumed, but has an additional component associated with cluster 2.

description: Nella società francese, a partire dallo sgretolamento del suo ruolo di potenza coloniale verso la fine degli anni Cinquanta del secolo scorso, si sono verificati significativi cambiamenti di paradigma. Una realtà, questa, che si è andata riflettendo gradualmente sullo schermo e nella narrativa di viaggio. A sua volta, tutto ciò ha portato verso un crescente interesse nei confronti del road movie, genere per definizione capace di sfidare binomi apparentemente duraturi come i confini, l’identità e lo spazio. Il viaggio stabilisce una distanza temporale e geografica, ma anche dei luoghi attraverso cui la società e il ruolo che ciascuno occupa al suo interno possono venire meglio rappresentati. Recenti produzioni come Lontano (Loin, 2001) di André Téchiné, Viaggio alla Mecca (Le grand voyage, 2004) di Ismaël Ferroukhi e Exils (2005) di Tony Gatlif, tutte incentrate su viaggi di partenza dalla Francia, esemplificano molto bene questo trend. Il presente contributo è dedicato all’analisi di Le voyage en Arménie (2006) di Robert Guédiguian, un’opera superficialmente affine nei temi e negli interessi agli esempi citati, ma che tuttavia si discosta notevolmente sotto diversi aspetti dai recenti road movie francesi.

description: This study provides an analysis of the effects of a potential transatlantic free trade agreement (TTIP) on the US state of South Carolina agricultural exports and trade. Trade benefits are evaluated within the framework of static and dynamic gravity models. The panel gravity models and probit equations that account for zero trades are estimated by methods that deal with various effects. The results show that dynamic system GMM is the preferred estimator. World country panel trade data from 1989 to 2018 were used. The findings reveal that the TTIP would increase South Carolina agricultural among member countries. The other major regional blocks including the EU, ASEAN, and MERCOSUR are shown to be significant destination markets for South Carolina agricultural and exports and trade

Linear response theory and damped modes of stellar clusters

Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Because all stars contribute to its gravitational potential, stellar clusters amplify perturbations collectively. In the limit of small fluctuations, this is described through linear response theory, via the so-called response matrix. While the evaluation of this matrix is somewhat straightforward for unstable modes (i.e. with a positive growth rate), it requires a careful analytic continuation for damped modes (i.e. with a negative growth rate). We present a generic method to perform such a calculation in spherically symmetric stellar clusters. When applied to an isotropic isochrone cluster, we recover the presence of a low-frequency weakly damped $\ell = 1$ mode. We finally use a set of direct $N$-body simulations to test explicitly this prediction through the statistics of the correlated random walk undergone by a cluster's density centre.

description: In the pursuit of a reduced energy demand of VVC decoders, it was found that the coding tool configuration has a substantial influence on the bit rate efficiency and the decoding energy demand. The Advanced Design Space Exploration algorithm as proposed in the literature, can derive coding tool configurations that provide optimal trade-offs between rate and energy efficiency. Yet, some trade-off points in the design space cannot be reached with the state-of-the-art methodology, which defines coding tools for an entire bitstream. This work proposes a novel, granular adjustment of the coding tool usage in VVC. Consequently, the optimization algorithm is adjusted to explore coding tool configurations that operate on frame-level. Moreover, new optimization criteria are introduced to focus the search on specific bit rates. As a result, coding tool configurations are obtained which yield so far inaccessible trade-offs between bit rate efficiency and decoding energy demand for VVC-coded sequences. The proposed methodology extends the design space and enhances the continuity of the Pareto front.

description: In this investigation, we attempt to identify and to examine the determinants of agricultural exports in Tunisia. To achieve this aim, we used annual data for the period 1972 – 2017 and seven ad hoc specifications. Empirical results of each specification show us that gross domestic product in the agricultural sector, agricultural imports, bank loans to the agricultural sector and imports of agricultural machinery have a positive effect on agricultural exports in the long run. Conversely, domestic investments in the agricultural sector and the exploitation of agricultural land have a negative effect on agricultural exports in the long term. In the short term, only domestic investments in the agricultural sector cause agricultural exports. Findings and interpretations provide evidence that is very substantial to inspire validity planning and reforms to ameliorate agricultural investment and agricultural trade, so it can uphold economic development in Tunisia

description: We present an unbiased orbit solution and mass determination of the components of the eclipsing binary NY Vir as a critical test for the formation scenarios of subdwarf B stars. We obtained high-resolution time series VLT/UVES spectra and high-speed multicolour VLT/ULTRACAM photometric observations of NY Vir, a rapidly pulsating subdwarf B star in a short period eclipsing binary. Combining the radial velocity curve obtained from the VLT/UVES spectra with the VLT/ULTRACAM multicolour lightcurves, we determined numerical orbital solutions for this eclipsing binary. Due to the large number of free parameters and their strong correlations, no unique solution could be found, only families of solutions. We present three solutions of equal statistical significance, two of which are compatible with the primary having gone through a core He-flash and a common-envelope phase described by the $α$-formalism. These two models have an sdB primary of 0.466 \msol and 0.389 \msol, respectively. Finally, we report the detection of the Rossiter-McLaughlin effect for NY Vir.

 Remark: Tetranychus urticae was first described on Glyine max and Urtica sp from Germany (Koch, 1836). It is one of the most cosmopolitan spider mite species with worldwide distribution and a wide host range. It is considered a pest of many crops and is the most studied spider mite species with a high rate of pesticide resistance reported on this species by many authors. In Kenya, it is a major menace in cut flower production especially in Rosa sp. Its first record in Kenya was on Allium ampeloprasum (Alliaceae) from Machakos district and on Lathyrus odorata (Fabaceae) from Nairobi (Baker and Pritchard, 1960).

description: The financial ratios are the key indicators to assess the strength and weaknesses of company performance. In the stock market, capital gain plays a pivotal role to attract investors in the value of a firm’s stock investment, while the stock of agribusiness firms becomes a potential outlook to be investigated. The study aims to describe the predictability of capital gain by using financial ratios, namely dividend yield (DY), earnings yield (EY), a book to market (BM), debt-equity ratio (DER), and return on asset (ROA). The panel data model, generalized least square, ordinary least square, is applied to estimate the predictive regression both in separated and combined models. The result discloses that the majority of individual financial ratios can predict future capital gain on agribusiness stock except for the debt-equity ratio (DER). While the book to market value (BM) has the highest predictive power among other variables. Moreover, the predictability of capital gain is considerably enhanced by applying the combination of financial ratios

description: As 5th Generation research reaches the twilight, the research community must go beyond 5G and look towards the 2030 connectivity landscape, namely 6G. In this context, this work takes a step towards the 6G vision by proposing a next generation communication platform, which aims to extend the rigid coverage area of fixed deployment networks by considering virtual mobile small cells (MSC) that are created on demand. Relying on emerging computing paradigms such as NFV (Network Function Virtualization) and SDN (Software Defined Networking), these cells can harness radio and networking capability locally reducing protocol signaling latency and overhead. These MSCs constitute an intelligent pool of networking resources that can collaborate to form a wireless network of MSCs providing a communication platform for localized, ubiquitous and reliable connectivity. The technology enablers for implementing the MSC concept are also addressed in terms of virtualization, lightweight wireless security, and energy efficient RF. The benefits of the MSC architecture towards reliable and efficient cell offloading are demonstrated as a use-case.

Effects of Rotation on Vorticity Dynamics on a Sphere with Discrete Exterior Calculus

description: We investigate incompressible, inviscid vorticity dynamics on a rotating unit sphere using a Discrete Exterior Calculus (DEC) scheme. For a prescribed initial vorticity distribution, we vary the rate of rotation of the sphere from zero (non-rotating case, which corresponds to infinite Rossby number (Ro)) to 320 (which corresponds to Ro = $1.30 \times 10^{-3}$), and investigate the evolution with time of the vorticity field. For the non-rotating case, the vortices evolve into thin filaments due to so-called forward/direct enstrophy cascade. At late times an oscillating quadrupolar vortical field emerges as a result of the inverse energy cascade. Rotation diminishes the forward cascade of enstrophy (and hence the inverse cascade of energy) and tend to align the vortical structures in the azimuthal/zonal direction. Our investigation reveals that, for the initial vorticity field comprising of intermediate-wavenumber spherical harmonics, the zonalization of the vortical structures is not monotonic with ever decreasing Rossby numbers and the structures revert back to a non-zonal state below a certain Rossby number. On the other hand, for the initial vorticity field comprising of intermediate to large-wavenumber spherical harmonics, the zonalization is monotonic with decreasing Rossby number. Although, rotation diminishes the forward cascade of enstrophy, it does not completely cease/arrest the cascade.
Deposition dynamics of Na monomers and dimers on an Ar(001) substrate

description: We study deposition dynamics of Na and Na$_2$ on an Ar substrate, both species neutral as well as charged. The system is modeled by a hierarchical approach describing the Na valence electrons by time-dependent density-functional theory while Na core, Ar atoms and their dynamical polarizability are treated by molecular dynamics. We explore effects of Na charge and initial kinetic energy of the impinging Na system. We find that neutral Na is captured into a loosely bound adsorbate state for sufficiently low impact energy. The charged monomers are more efficiently captured and the cation Na$^+$ even penetrates the surface layer. For charged dimers, we come to different final configurations depending on the process, direct deposit of Na$_2^+$ as a whole, or sequential deposit. In any case, charge dramatically amplifies the excitation of the matrix, in particular at the side of the Ar dipoles. The presence of a charge also enhances the binding to the surface and favours accumulation of larger compounds.

description: This study aimed to investigate the point of view of consumers in developing and emerging market about the genetically modified and non-genetically modified food based on the evidence from soymilk non- genetically modified product. The experimental auction method was employed to explicit the willingness-to-pay of Vietnamese consumers for a non-genetically modified soymilk products. Regression analysis was applied to determine factors influencing consumer's WTP for non-genetically modified product. The results indicated that consumers are willing to pay 84% premium for soy milk with non-genetically modified attribute information in comparison with the conventional one. The level of WTP derived from the auction is not much different from the market price of the product being auctioned. Notably, consumers with high level of risk aversion were likely to purchase non-genetically modified food. This was a predominant factor that determines who would accept or deny the consumption of non-genetically modified food.
Alpine melanism in the butterfly Parnassius phoebus F. (Lepidoptera : Papilionidae)
Creators: name: Guppy, Crispin Spencer
Publisher: name: University of British Columbia
Year: 2010

description: Alpine melanism, a tendency to become darker with increased elevation and latitude, occurs in many species of butterflies. In Parnassius phoebus (Papilionidae) it has been assumed that alpine melanism is the result of adaptation to colder environments at higher elevations and latitudes, owing to the ability of darker wings to transfer more solar energy to the body as heat. I examined five independently variable components of wing melanism for agreement with this hypothesis, as well as the subsidiary hypothesis that size is inversely correlated to melanism because it also affects thermoregulation. Basal patch blackness (proportion of scales which are black) in both sexes is well correlated with elevation, latitude, and air temperature during the flight season. In males, increased basal patch blackness is advantageous because it increases the proportion of total time spent in flight looking for mates, but is locally disadvantageous because it increases the probability of dispersal. Basal patch width is only poorly correlated with elevation, latitude, and air temperature during the flight season in males, and not correlated in females. Increased patch width also results in increased flight activity, but does not affect dispersal. Basal wing transparency has little correlation with elevation, and no effect on activity, although it does slightly affect body temperature. Within individual mountains, distal wing blackness and transparency are correlated with elevation, but show no correlation when many mountains are considered together. Distal wing characters have no effect on flight activity or dispersal. Size is well correlated with elevation and latitude, but is less well correlated with air temperature. Smaller males disappear from the population more rapidly than large males, apparently through increased mortality because small males do not disperse more rapidly. Females disperse more than males, with larger females dispersing more than smaller females. Variation in basal patch blackness may have a similar adaptive significance in both sexes, but all the other melanism characters appear to have a different significance for each sex. I develop a new hypothesis for the mechanism of the effect of wing color on thermoregulation in dorsal basking butterflies. I suggest that most transfer of solar radiation to the body by the wings occurs while in flight, rather than while dorsal basking on a substrate. This hypothesis is used to explain the observation that the minimum levels of air temperature and solar radiation at which flight can occur does not depend on wing color in Parnassius phoebus, in contrast to phenotype dependent flight thresholds in lateral basking Colias.

description: Formal verification methods for concurrent systems cannot always be scaled-down or tailored in order to be applied on specific subsystems. We address such an issue in a MultiParty Session Types setting by devising a partial type assignment system for multiparty sessions (i.e. sets of concurrent participants) with asynchronous communications. Sessions are possibly typed by "asynchronous global types" describing the overall behaviour of specific subsets of participants only (from which the word "partial"). Typability is proven to ensure that sessions enjoy the partial versions of the well-known properties of lock- and orphan-message-freedom.
