description: Function-as-a-Service (FaaS) is one form of the serverless cloud computing paradigm and is defined through FaaS platforms (e.g., AWS Lambda) executing event-triggered code snippets (i.e., functions). Many studies that empirically evaluate the performance of such FaaS platforms have started to appear but we are currently lacking a comprehensive understanding of the overall domain. To address this gap, we conducted a multivocal literature review (MLR) covering 112 studies from academic (51) and grey (61) literature. We find that existing work mainly studies the AWS Lambda platform and focuses on micro-benchmarks using simple functions to measure CPU speed and FaaS platform overhead (i.e., container cold starts). Further, we discover a mismatch between academic and industrial sources on tested platform configurations, find that function triggers remain insufficiently studied, and identify HTTP API gateways and cloud storages as the most used external service integrations. Following existing guidelines on experimentation in cloud systems, we discover many flaws threatening the reproducibility of experiments presented in the surveyed studies. We conclude with a discussion of gaps in literature and highlight methodological suggestions that may serve to improve future FaaS performance evaluation studies.

description: We present the growth morphology, the long range ordering, and the evolution of the valence band electronic states of ultra-thin films of copper phthalocyanine (CuPc) deposited on the Au(110)-(1x2) reconstructed surface, as a function of the organic molecule coverage. The Low Energy Electron Diffraction (LEED) patterns present a (5x3) reconstruction from the early adsorption stages. High-Resolution UV photoelectron spectroscopy (HR-UPS) data show the disappearance of the Au surface states related to the (1x2) reconstruction, and the presence of new electronic features related to the molecule-substrate interaction and to the CuPc molecular states. The CuPc highest occupied molecular orbital (HOMO) gradually emerges in the valence band, while the interface electronic states are quenched, upon increasing the coverage.

title: The role of phosphatidic acid in astrocyte intracellular signalling
Creators: name: Jakobson, Katherine
Publisher: name: The Open University
Year: 1991

description: 1. Astrocyte-enriched cultures prepared from the neonatal rat cerebral cortex were used to assess the effects of putative mitogens on astroglial proliferation. Subconfluent cultures, 11 div, were deprived of serum, thus halting cell division, and then exposed to these agents. 10% v/v foetal 3 calf serum elicited increases in [ H]thymidine incorporation into astrocyte DNA ranging from 245% to 434% over control. Insulin elicited a dose-dependent increase in [3H]thymidine incorporation (EC50 = 16y(Uml-1 ). Platelet-derived growth factor and phosphatidic acid had a biphasic effect on 3 [ H]thymidine incorporation apparently due to the presence of high concentrations of their respective vehicles, ethanediol and CHCl3:MeOH (1:2 v/v), at the higher mitogen concentrations tested. 2. The effects of platelet-derived growth factor and 3 phosphatidic acid on [3H]thymidine incorporation were dependent upon the age of the cultures used. For example, at 5 div platelet-derived growth factor reduced incorporation whereas phosphatidic acid increased incorporation compared to control. 3. The phosphatidic acid mitogenic signal could be amplified from a 13% to 43% increase over control by increasing the time of serum depletion from 24h to 48h. The mitogenic effect of phosphatidic acid was dependent upon the presence of long chain fatty acids. 4. Prolonged phorbol ester pretreatment, abolished the mitogenic action of phosphatidic acid on astrocytes and also reduced that of 10% v/v foetal calf serum by 41%. 5. In order to determine whether the mitogenic effects of phosphatidic acid involved phosphoinositide turnover cultures prelabelled with [3H]inositol were exposed to phosphatidic acid and inositol phosphates accumulation and inositol phospholipid labelling monitored. Phosphatidic acid elicited a dose- and time-dependent increase in the accumulation of total and individual labelled inositol phosphates which was dependent upon a low extracellular calcium concentration and phosphatidic acid containing long chain fatty acids. 6. Phosphatidic acid stimulated changes in inositol phospholipid labelling and 45Ca++ efflux and both effects were dependent on phosphatidic acid containing long chain fatty acids. 7. Phosphatidic acid had no detectable effect on phosphoinositide turnover but did stimulate 45Ca++ efflux from fibroblasts. 8. The possible release of phosphatidic acid from agonist-stimulated astrocytes was studied by exposing [3H]arachidonic acid prelabelled cultures to carbachol, ATP and noradrenaline. All three agonists increased the formation of labelled phosphatidic acid but they did not evoke phosphatidic acid release from astrocytes. 9. R59 022, a diacylglycerol kinase inhibitor, inhibited carbachol-stimulated phosphatidic acid production and 45Ca++ efflux but had no effect on carbachol-induced phosphoinositide turnover.

description: We present our measurements of the H$α$, [OIII], and [OII] luminosity functions as part of the Lyman Alpha Galaxies at Epoch of Reionization (LAGER) survey using our samples of 1577 $z = 0.47$ H$α$-, 3933 $z = 0.93$ [OIII]-, and 5367 $z = 1.59$ [OII]-selected emission line galaxies in a single 3 deg$^2$ CTIO/Blanco DECam pointing of the COSMOS field. Our observations reach 5$σ$ depths of $8.2\times10^{-18}$ erg s$^{-1}$ cm$^{-2}$ and comoving volumes of $(1-7)\times10^{5}$ Mpc$^3$ making our survey one of the deepest narrowband surveys. We measure the observed luminosity functions and find best-fits of $ϕ^\star = 10^{-3.16\pm0.09}$ Mpc$^{-3}$ and $L^\star = 10^{41.72\pm0.09}$ erg s$^{-1}$ for H$α$, $ϕ^\star = 10^{-2.16^{+0.10}_{-0.12}}$ Mpc$^{-3}$ and $L^\star = 10^{41.38^{+0.07}_{-0.06}}$ erg s$^{-1}$ for [OIII], and $ϕ^\star = 10^{-1.97^{+0.07}_{-0.07}}$ Mpc$^{-3}$ and $L^\star = 10^{41.66\pm0.03}$ erg s$^{-1}$ for [OII], with $α$ fixed to $-1.75$, $-1.6$, and $-1.3$, respectively. An excess of bright $> 10^{42}$ erg s$^{-1}$ [OIII] emitters is observed and may be due to AGN contamination. Dust corrections are applied assuming $A_{\rm{H}α} = 1$ mag. We also design our own empirical rest-frame $g - r$ calibration using SDSS DR12 data, test it against our $z = 0.47$ H$α$ emitters with $z$COSMOS $1$D spectra, and calibrate it for $(g - r)$ between $-0.8$ and $1.3$ mag. Dust and AGN-corrected star formation rate densities (SFRDs) are measured as $\log_{10}ρ_{\rm{SFR}}/(\rm{M}_\odot\ \rm{yr}^{-1}\ \rm{Mpc}^{-3}) = -1.63\pm0.04$, $-1.07\pm0.06$, and $-0.90\pm0.10$ for H$α$, [OIII], and [OII], respectively. We find our [OIII] and [OII] samples fully trace cosmic star formation activity at their respective redshifts in comparison to multi-wavelength SFRDs, while the H$α$ sample traces $\sim 70$ percent of the total $z = 0.47$ SFRD.

description: This work is devoted to the definition of the concept of "collaboration" in the system of pedagogical sciences, as well as the study of collaboration as a form of pedagogical interaction. The relevance of the study is due, on the one hand, to the increasing frequency of references by pedagogical researchers to the concept of "collaboration", and on the other hand, to the high degree of inconsistency of scientists in defining this phenomenon in the system of educational sciences.

description: We report the observation of a parametric instability in the out-of-equilibrium steady state of two coupled Kerr microresonators coherently driven by a laser. Using a resonant excitation, we drive the system into an unstable regime, where we observe the appearance of intense and well resolved sideband modes in the emission spectrum. This feature is a characteristic signature of self-sustained oscillations of the intracavity field. We comprehensively model our findings using semiclassical Langevin equations for the cavity field dynamics combined with a linear stability analysis. The inherent scalability of our semiconductor platform, enriched with a strong Kerr nonlinearity, is promising for the realization of integrated optical parametric oscillator networks operating in a few-photon regime.

description: Nigerian economy is suffering from recession which may have resulted from the long overreliance on mono-product ( crude oil) exploitation. There is the general view that diversifying into non-oil sector will save Nigeria from the present economic downturn. Believing that diversification into agriculture will bring a solution to the present situation. This paper aimed at identifying the agricultural product(s) that has (have) more and short-run potential of delivering the country from the recession. The analysis is descriptive using secondary data from the Central bank of Nigeria and National Bureau of Statistics for the period 2010-20 ~ 6. Findings showed that fast and high yielding crops such as maize, sesame seeds, and soybean and fish production can go ·a long way in rescuing the situation. More investments into these commodities are therefore, recommended.

description: With a contribution of up to 71 % to world output of yam, Nigeria remains the largest producing country with rural farmers having yam as second most commonly harvested tuber crop. Given its nutritional superiority to most roots and tubers in terms of digestible proteins and minerals and its relevance as a source of income for the poor majority of rural-farmers, the impo"rtance of yam in Nigeria cannot be overemphasized. There has however been a persistent price increasein yam, as well as other food· commodities, in Nigeria. This study was therefore designed to investigate the determinants of rising yam price in Nigeria over the period 1970-2015. The study relied on timeseries data sourced from FAOSTAT, Federal Bureau of Statistics and CBN Bulletin. Inferential statistics including unit-root test, cointegration and error correction model were employed in analysis. Autocorrelation was present in the model hence necessitating Cochrane-Orcutt approach. Results indicated that variables were non-stationary but became ·stationary after first differencing.At 5% signific.ance level, on the long run, price of yam was determined by annual production (coef.=- 0.8095), GDP (coef.=-3.009) and annual money supply (coef.=:0.829). It is consequently recommended that programmes and strategies implemented to boost food production in Nigeria should be carried on viz-a-viz robust economic planning that keeps the significant macroeconomic variables at optimal levels in order to maintain the balance required for stabilization in food commodity prices. Likewise, efforts should be concerted in putting insurgency in Nigeria under checks considering the ill effect it has on farming and trading activities.
On the Evidence for Clustering in the Arrival Directions of AGASA's Ultrahigh Energy Cosmic Rays

description: Previous analyses of cosmic rays above 40 EeV observed by the AGASA experiment have suggested that their arrival directions may be clustered. However, estimates of the chance probability of this clustering signal vary from 10^{-2} to 10^{-6} and beyond. It is essential that the strength of this evidence be well understood in order to compare it with anisotropy studies in other cosmic ray experiments. We apply two methods for extracting a meaningful significance from this data set: one can scan for the cuts which optimize the clustering signal, using simulations to determine the appropriate statistical penalty for the scan. This analysis finds a chance probability of about 0.3%. Alternatively, one can optimize the cuts with a first set of data, and then apply them to the remaining data directly without statistical penalty. One can extend the statistical power of this test by considering cross-correlation between the initial data and the remaining data, as long as the initial clustering signal is not included. While the scan is more useful in general, in the present case only splitting the data set offers an unbiased test of the clustering hypothesis. Using this test we find that the AGASA data is consistent at the 8% level with the null hypothesis of isotropically distributed arrival directions.

title: Investigation into Melt Overflow of Alloys
Creators: name: Kalkanli, Ali
Publisher: name: The Open University
Year: 1992

description: The possibility of direct strip casting onto a single rotary chiller has been investigated. A number of alloys including Fe-Cr-Ni, Fe-Ni and Fe-Cr-Al were tested and strips were produced. Strip formation has been modelled theoretically studying two basic consideration: a) Liquid film formation prior to recalescence due to momentum transfer, b) Strip formation in a melt puddle by one dimensional heat transfer across the wheel/strip interface. Experimental modelling of the melt overflow process has been undertaken, to: a) investigate casting instabilities and associated limitations of direct strip casting and, b) reveal the effects of process parameters such as surface tension, viscosity and liquid metal depth on the final characteristics of the strip.

 The melt overflow process has been employed for the production of strips, ribbons and fibres with thicknesses ranging between 150-700 μm. A special crucible(2.5 kg capacity) and plunger mechanism was designed and developed for producing up to 30 mm wide directly cast strip from a mini induction furnace. The most efficient pouring channel geometry was determined to minimize the heat losses within the channel and maintain sufficient hot liquid metal flow steadily during the melt overflow. The test material was based on 304 stainless Steel. The critical casting speeds and alloy compositions necessary to produce uniform strips without serrations were determined. Surface tension was modified by the addition of deoxidizing agents and sulphur. Surface tension values were measured by a modified oscillation droplet technique. The lowest value of surface tension in stainless steel was found to be 1.43 N.m-1 at a casting temperature of 1600 °C for sulphur at per cent 0.073. This alloy yielded strip with edge serrations and poor strip quality in contrast to an alloy with a surface tension of 1.98 N.m-1 at a casting temperature of 1580 °C with sulphur content 0.023. Uniform strips were obtained for this case.

 The capillary number which is a ratio of viscous forces to surface tension forces in a liquid film were calculated for 304 stainless steel strips as 0.006-0.009 for corresponding thickness values 175-190 μm. High speed photography, video and specialised photographic techniques were utilised to examine Kelvin-Helmholtz instability and the temperature distribution during the residence time of the strip on the wheel.

 As cast strip microstructures wore found to consist of dendritic and cellular solidification structures consistent with a cooling rate of 104 K.s-1.

description: We present results from high speed photometry of a further thirteen faint cataclysmic variables. V356 Aql (Nova Aql 1936) shows flare-like outbursts with recurrence time scales ~ 3000 s, but no coherent periodicities. Aqr1 is an intermediate polar with a spin period of 6.7284 min and a probable orbital period P(orb) = 3.226 h derived from orbital sidebands. Its orbital sideband frequencies show very variable amplitudes. The published spectroscopic period of 2.0 h suggests that Aqr1 is similar to GW Lib and FS Aur in having an additional periodicity of unknown origin. FIRST J1023+0038 has P(orb) = 4.7548 h with an orbital modulation of range 0.45 mag, probably caused by reflection effect from a hot white dwarf primary; as such it may have been a nova sometime in the past few decades. Ha 0242 is a deeply eclipsing very low mass-transfer rate system, probably a dwarf nova of very long outburst interval, with P(orb) = 1.792 h. GI Mon, an old nova, has optical modulations at 4.325 h and possibly also at 48.6 min and is thus a candidate intermediate polar. AO Oct, an SU UMa type dwarf nova, shows orbital modulation at quiescence with P(orb) = 94.097 min. V972 Oph (Nova Ophiuchi 1957) showed no flickering activity during one set of observations, but did so at a later time, confirming the correctness of the identification of this object, but it shows no orbital modulation. SDSS 0155 is a deeply eclipsing polar with an orbital period of 87.13 min. SDSS 0233 shows flaring activity but no discernible periodicity. No periodicity was found in the new AM CVn candidate SDSS 1240. SDSS 1556 shows a periodic modulation at 1.778 h which is possibly due to orbital motion. SDSS 2050 is an eclipsing polar with P(orb) = 1.5702 h. FH Ser (Nova Serpentis 1970) has strong flickering activity but no detectable orbital modulation.

Publisher: name: The University of British Columbia

description: Responding to Article 13 of the United Nations Declaration on the Rights of Indigenous Peoples (United Nations 2008), this research centred on the mobilization of Indigenous knowledge and epistemologies through the creation of Indigenous curriculum resource materials for an intermediate classroom in a First Nations school. This research is crucial because there is a gap between talking about Indigenous Knowledges and the transmission of Indigenous Intellectualism. Indigenous scholarship is now focused on developing Indigenous theoretical models to support identity resurgence, epistemologies, and practices within First Nations communities. This research integrates three Indigenous philosophical stances: Red Pedagogy, Resurgence, Radical Indigenism and four Stó:lō principles: Sxwōxwiyám [Ancient Narratives], Shxwelí [Understanding of Life-force], Shxwélméxwelh [Life-ways], Xwelméxwqel [The Language] to establish the framework for a theoretical model of Indigenous curriculum design (S'iwesá:ylhem [Teachings for the Children]). Using Curriculum Action Research (McKernan, 1998), Stó:lō specific curriculum resource materials were created and implemented. This case-study found that the primary factor in successful curriculum design and positive student engagement with the curriculum resource materials was relationship, especially with Stó:lō historian Naxaxalhts'i who has collected many of the sxwōxwiyám used in the content. In conclusion, this research offers five recommendations for educational researchers: (1) There needs to be further research into unpacking the Stó:lō intelligences embedded in sxwōxwiyám, (2) There is a need for curriculum action research that would work toward a coherent progression of Stó:lō sxwōxwiyám in the curriculum, (3) There is a need to create a Halq’eméylem dictionary for elementary students, (4) There are research opportunities to explore how to best establish technology infrastructures and utilize technology in curriculum resource development, and (5) There is a need for longitudinal research projects on Indigenous curriculum development and Indigenous curriculum resource materials development.

description: We consider the possibility that, in the semiclassical Einstein equation for cosmological spacetimes, gravity is sourced by the amount of stress-energy that is above that of the instantaneous ground state. For this possibility to be consistent, the Bianchi identities must continue to hold. This is nontrivial because it means that the ground state expectation value of the stress-energy tensor must be covariantly conserved in spite of the fact that the ground state is generally a different state at different times. We prove that this consistency condition does hold. As a consequence, we find that the vacuum stress-energy which is above the instantaneous ground state does not renormalize the cosmological constant, as long as the instantaneous ground states and the instantaneous adiabatic vacua exist.

description: Contemporary markets that are distinguished by high degree of instability have prompted the necessity for correction of development models in all economies that are market-orientated and aspiring to be competitive on a global level. As a response to the challenge, many countries have ’turned’ to the sector of small and medium-size companies that have the necessary degree of business flexibility and adaptibility in response to external influences. The fundamental development resource of the „small business“ subject is the entrepreneurship. Understanding of this concept is a primary prerequisite of its implementation. Thus, the aim of thispaper is to highlight the main characteristics and implications of entrepreneurship, with a special emphasis on agro-business, cosidering the importance of this area not only in economical parameters.

description: Knowledge and innovation have had the biggest significance in development since the very beginnings of human civilization. However, globalisation and technological revolution in the last few decades have made knowledge a key factor of macro competitiveness and economic growth in certain countries. Both developed and developing countries tend to raise the level of their own readiness for development of knowledge economy to the greatest possible extent. Putting knowledge in the center of economic processes, economy is being transformed to knowledge economy. Assesing countries’ readiness to develop knowledge-based economy is significant due to the fact that results will be the basis for defining development policy and a necessary element of its implementation at different levels of economic structure of society.

description: Transiting planets orbiting bright stars are the most favorable targets for follow-up and characterization. We report the discovery of the transiting hot Jupiter XO-7 b and of a second, massive companion on a wide orbit around a circumpolar, bright, and metal rich G0 dwarf (V = 10.52, $T_{\rm eff} = 6250 \pm 100 \; \rm K$, $\rm[Fe/H] = 0.432 \pm 0.057 \; \rm dex$). We conducted photometric and radial velocity follow-up with a team of amateur and professional astronomers. XO-7 b has a period of $ 2.8641424 \pm 0.0000043$ days, a mass of $0.709 \pm 0.034 \; \rm M_{\rm J}$, a radius of $1.373 \pm 0.026 \; \rm R_{\rm J}$, a density of $0.340 \pm 0.027 \; \rm g \, {cm}^{-3}$, and an equilibrium temperature of $1743 \pm 23 \; \rm K$. Its large atmospheric scale height and the brightness of the host star make it well suited to atmospheric characterization. The wide orbit companion is detected as a linear trend in radial velocities with an amplitude of $\sim100 \; \rm m \, {s}^{-1}$ over two years, yielding a minimum mass of $4 \; \rm M_{\rm J}$; it could be a planet, a brown dwarf, or a low mass star. The hot Jupiter orbital parameters and the presence of the wide orbit companion point towards a high eccentricity migration for the hot Jupiter. Overall, this system will be valuable to understand the atmospheric properties and migration mechanisms of hot Jupiters and will help constrain the formation and evolution models of gas giant exoplanets.

Unusual Ground State Properties of the Kondo-Lattice Compound Yb2Ir3Ge5

description: We report sample preparation, structure, electrical resistivity, magnetic susceptibility and heat capacity studies of a new compound Yb$_2$Ir$_3$Ge$_5$. We find that this compound crystallizes in an orthorhombic structure with a space group PMMN unlike the compound Ce$_2$Ir$_3$Ge$_5$ which crystallizes in the tetragonal IBAM (U$_2$Co$_3$Si$_5$ type) structure. Our resistivity measurements indicate that the compound Yb$_2$Ir$_3$Ge$_5$ behaves like a typical Kondo lattice system with no ordering down to 0.4 K. However, a Curie-Weiss fit of the inverse magnetic susceptibility above 100 K gives an effective moment of only 3.66 $μ$$_B$ which is considerably less than the theoretical value of 4.54 $μ$$_B$ for magnetic Yb$^3+$ ions. The value of $θ_{P}$ = -15.19 K is also considerably higher indicating the presence of strong hybridization. An upturn in the low temperature heat capacity gives an indication that the system may order magnetically just below the lowest temperature of our heat capacity measurements (0.4 K). The structure contains two sites for Yb ions and the present investigation suggests that Yb may be trivalent in one site while it may be significantly lower (close to divalent) in the other.

description: We study the zero-temperature phase diagram of a dissipationless and disorder-free Josephson junction chain. Namely, we determine the critical Josephson energy below which the chain becomes insulating, as a function of the ratio of two capacitances: the capacitance of each Josephson junction and the capacitance between each superconducting island and the ground. We develop an imaginary-time path integral Quantum Monte-Carlo algorithm in the charge representation, which enables us to efficiently handle the electrostatic part of the chain Hamiltonian. We find that a large part of the phase diagram is determined by anharmonic corrections which are not captured by the standard Kosterlitz-Thouless renormalization group description of the transition.

description: In this paper we will deal with the research of economic growth and economic outlook in the countries of Eastern Europe, that is Russia and Ukraine in 2014. To ensure the inflow of foreign capital in the country’s transition had to create the appropriate economic environment for multinational corporations. Eastern European countries in transition were forced to quickly and effectively liberalize the market in order to attract foreign capital if they wanted to enhance their own growth and development as well as to increase the competitiveness of their own economy. Countries were required to solve problems in the judiciary, to strengthen the security and efficiency of the legal protection of property and contract, to resolutely fight corruption and abuse of office, to increase speed, reduce costs and simplify administrative procedures, to develop the domestic capital market.

description: We investigate simplified models involving an inert scalar triplet and vector-like leptons that can account for the muon $g-2$ anomaly. These simplified scenarios are embedded in a model that features W' and Z' bosons, which are subject to stringent collider bounds. The constraints coming from the muon $g-2$ anomaly are put into perspective with collider bounds, as well as bounds coming from lepton flavor violation searches. The region of parameter space that explains the $g-2$ anomaly is shown to be within reach of lepton flavor violation probes and future colliders such as HL-LHC and HE-LHC.

description: We present a microscopic theory for the recently observed reentrant integral quantum Hall effect in the n=1 and n=2 Landau levels. Our energy investigations indicate an alternating sequence of M-electron-bubble and quantum-liquid ground states in a certain range of the partial filling factor of the n-th level. Whereas the quantum-liquid states display the fractional quantum Hall effect, the bubble phases are insulating, and the Hall resistance is thus quantized at integral values of the total filling factor.
