description: Quantum liquids, in which an effective Lorentzian metric and thus some kind of gravity gradually arise in the low-energy corner, are the objects where the problems related to the quantum vacuum can be investigated in detail. In particular, they provide the possible solution of the cosmological constant problem: why the vacuum energy is by 120 orders of magnitude smaller than the estimation from the relativistic quantum field theory. The almost complete cancellation of the cosmological constant does not require any fine tuning and comes from the fundamental ``trans-Planckian'' physics of quantum liquids. The remaining vacuum energy is generated by the perturbations of quantum vacuum caused by matter (quasiparticles), curvature, and other possible sources, such as smooth component -- the quintessence. This provides the possible solution of another cosmological constant problem: why the present cosmological constant is on the order of the present matter density of the Universe. We discuss here some properties of the quantum vacuum in quantum liquids: the vacuum energy under different conditions; excitations above the vacuum state and the effective acoustic metric for them provided by the motion of the vacuum; Casimir effect, etc.

description: We show how within the Dijkgraaf-Vafa prescription one can derive superpotentials for matter fields. The ingredients forming the non-perturbative Affleck-Dine-Seiberg superpotentials arise from constrained matrix integrals, which are equivalent to classical complex Wishart random matrices. The mechanism is similar to the way the Veneziano-Yankielowicz superpotential arises from the matrix model measure.

description: It is widely accepted that the usage of the personal computer and the Internet can improve efficiency in the agricultural sector. Despite the fact that Information and Communication Technologies (ICTs) have evolved rapidly, the farmers are lagging behind in the use of ICTs. This study examines the factors that affect the usage of personal computers and the Internet by Cypriot farmers, by analyzing data from 526 farmers, selected by using the stratified random sampling method. Logit models are used to examine the socioeconomic characteristics of Cypriot farmers that may affect the usage or not, of the personal computer and the Internet. The results showed that 60.6% of them use the personal computer and 54.2% use the Internet. From the analysis of the logit models it was found that the age, the educational level, the income, the type of agricultural activities and the location of the farm, are significant determinants for the personal computer and the Internet usage. Future research is needed to examine the personal computer and Internet applications, their usefulness and the possible benefits for the Cypriot farmers from their usage.

description: This article examines the impact of parallel supply shifts that cause supply to transition from elastic to inelastic on consumer, producer, and total surplus. We show that parallel rightward shifts of the supply curve cause consumer surplus and total surplus to increase unambiguously. On the other hand, producer surplus increases, reaches a maximum in the inelastic portion of both the demand and supply curves and then declines. This implies that innovations of this sort eventually result in consumers appropriating a higher share of total surplus. Finally, the maximum points for various producer surplus curves fall on a line which begins at the highest point of the total revenue curve and ends at the lower right corner of the total revenue curve.

description: The pursuit of development remains a paramount concern for nations worldwide, with Nigeria grappling to address pressing developmental challenges amidst its vast material, cultural, and human resources. Despite its potential, Nigeria's development indicators paint a sobering picture, with poverty levels exceeding 70%, a stark contrast to its abundance of resources. Various initiatives, both domestic and international, have been implemented in a bid to spur development within the country. Domestically, efforts such as the Seven Point Agenda under the Umar Yar Adua administration, the National Economic Empowerment and Development Strategy (NEEDS), and the National Poverty Eradication Programme (NAPEP) have been initiated to tackle developmental issues. Additionally, Nigeria has committed to continental and global frameworks, including the New Partnership for African Development (NEPAD) and the Millennium Development Goals (MDGs), to further its development agenda.

This abstract highlights Nigeria's multifaceted approach to development, encapsulating both domestic policy initiatives and international commitments. It underscores the imperative of addressing entrenched challenges such as poverty within the context of abundant resources and diverse policy frameworks. By examining Nigeria's developmental trajectory and policy interventions, this paper contributes to a deeper understanding of the complexities inherent in pursuing development within a diverse socio-political landscape.

We show that beyond the mean field approximation the dissociation of a molecular condensate due to the chemical potential curve crossing leads to the formation of two modes condensate. We also show that these two modes are correlated in a two mode squeezed state.

description: The interiors of mature neutron stars are expected to be superfluid. Superfluidity of matter on the microscopic scale can have a number of large scale, potentially observable consequences, as the superfluid component of the star can now flow relative to the `normal' component that is tracked by electromagnetic emission. The most spectacular of such phenomena are pulsar glitches, sudden spin-ups observed in many pulsars. A background flow of a normal-fluid component with respect to the superfluid is also known to lead to a number of instabilities in laboratory superfluids, possibly leading to turbulence and modifying the nature of the mutual friction coupling between the two fluids. In this paper we consider modes of oscillation in the crust and core of a superfluid neutron star, by conducting a plane-wave analysis. We explicitly account for a background flow between the two components (as would be expected in the presence of pinning) and the entrainment, and we consider both standard (Hall-Vinen) and isotropic (Gorter-Mellink) forms of the mutual friction. We find that for standard mutual friction there are families of unstable inertial and sound waves both in the case of a counter-flow along the superfluid vortex axis and for counterflow perpendicular to the vortex axis and find that entrainment leads to a quantitative difference between instabilities in the crust and core of the star. For isotropic mutual friction we find no unstable modes, and speculate that instabilities in a straight vortex array may be linked to glitching behaviour, which then ceases until the turbulence has decayed.

description: In the current study determinants of cherry production and marketing in Pakistan are estimated. For the study cross sectional data set of 60 cherry producers was collected from Kalat and Ziarat districts of the Balochistan province. The analysis was carried out by employing a number of different econometric models and techniques like poison regression model was employed for estimating number of hectares under cherry orchard while logit model was employed for farmers’ decision making like selling at farm gate or taking the commodity to the market. Propensity score matching technique was employed for estimating the cherry net returns and cherry yield. The empirical results indicate that farmers selling cherry at market are obtaining higher net returns.

description: This study examines the impact of some main determinants of environmental behaviour, a priori identified in the scientific literature, on the Greek and British citizens’ perceptions about environmental protection and their actions to fight climate change. The study used Eurobarometer data and logistic regression and identified factors significantly influencing environmental perceptions and behaviour common in both countries. Perceptions of EU climate change policy and education significantly influence environmental perceptions of both Greek and British citizens. Access to information is the strongest determinant of environmental behaviour in both countries, followed by age, gender and occupation/purchasing power, and environmental attitudes and perceptions.

description: Allowing for the comparison of agricultural policies among countries and supporting the European integration process, a methodological tool was developed called the APM (Agri-Policy Measures tool). The tool enables the cross country qualitative and quantitative analysis of budgetary support to agriculture using uniform classification and systemization template primarily based on the current EU concept of the policy pillars. All agricultural policy measures are grounded on three main pillars: market and direct producer support measures, structural and rural development measures and general measures related to agriculture. Total budgetary support to agriculture should represent the sum of all transfers related to agriculture from all sources, but without administrative costs and transfers to non-agricultural sectors. The tool was applied for the analysis and comparison of agricultural policies in the Western Balkan countries and it proved to be useful for policy analysis in relation to the EU accession process.

description: Many multimedia applications require precise understanding of the rate-distortion characteristics measured by the function relating visual quality to media attributes, for which we term it the generalized rate-distortion (GRD) function. In this study, we explore the GRD behavior of compressed digital videos in a three-dimensional space of bitrate, resolution, and viewing device/condition. Our analysis on a large-scale video dataset reveals that empirical parametric models are systematically biased while exhaustive search methods require excessive computation time to depict the GRD surfaces. By exploiting the properties that all GRD functions share, we develop an Robust Axial-Monotonic Clough-Tocher (RAMCT) interpolation method to model the GRD function. This model allows us to accurately reconstruct the complete GRD function of a source video content from a moderate number of measurements. To further reduce the computational cost, we present a novel sampling scheme based on a probabilistic model and an information measure. The proposed sampling method constructs a sequence of quality queries by minimizing the overall informativeness in the remaining samples. Experimental results show that the proposed algorithm significantly outperforms state-of-the-art approaches in accuracy and efficiency. Finally, we demonstrate the usage of the proposed model in three applications: rate-distortion curve prediction, per-title encoding profile generation, and video encoder comparison.

description: The objective of this paper is to analyze consumer purchasing behaviour and preference for olive oil, in the Albanian context of a weakly enforced public and private quality assurance system. A consumer survey was administered at retail outlets in Tirana. Data analysis was performed using descriptive statistics and a two-step cluster analysis to identify homogeneous groups within the sample. The results indicate that most consumers perceive the quality of olive oil they consume to be very high and tend to rely on and trust in the producers/suppliers of the product, rather than public institutions as a guarantee of the quality and safety of olive oil purchased.

description: A project is said to be successful when it is completed within time frame and with standard quality (Frimpong et al, 2003). In project management a successful project can be defined as project is completed within approved time, cost and with standard quality (Trost & Oberlender, 2003). According to ( Aziz et al.,2016) highway project which is completed within the time frame or approved time is known as successful project.In Pakistan, transportation sector is knows as fourth largest sector which contributes more than 10% to (GDP) gross domestic production and over 17% to the (GCF) gross capital foundation (Javied and Hyder,2009). The government of Pakistan is trying to improve quality standards of highway network (ESP 2014-2015). Construction industry has always problem from fragmentation owing to the project execution and different financial, managerial and technical specialists that are in a project. So all projects should be completed on time and budget (Sullivan & Harris,1986). A number of researches have been found to find factors which cause delay in construction industry. However few researches have been carried out to find factors which cause delay in highway/road projects. In Pakistan, number of researches has been found to identify factors which causes delay in construction projects, only few studies have been found to identify critical factors which causes delay in highway projects.

description: The Internet of Things (IoT) envisions the creation of an environment where everyday objects (e.g. microwaves, fridges, cars, coffee machines, etc.) are connected to the internet and make users' lives more productive, efficient, and convenient. During this process, everyday objects capture a vast amount of data that can be used to understand individuals and their behaviours. In the current IoT ecosystems, such data is collected and used only by the respective IoT solutions. There is no formal way to share data with external entities. We believe this is very efficient and unfair for users. We believe that users, as data owners, should be able to control, manage, and share data about them in any way that they choose and make or gain value out of them. To achieve this, we proposed the Sensing as a Service (S2aaS) model. In this paper, we discuss the Sensing as a Service ecosystem in terms of its architecture, components and related user interaction designs. This paper aims to highlight the weaknesses of the current IoT ecosystem and to explain how S2aaS would eliminate those weaknesses. We also discuss how an everyday user may engage with the S2aaS ecosystem and design challenges.

 Remarks: Pterodroma phaeopygia is endemic to the Galápagos Islands. Although Dickinson (2003: 74) listed it as the subspecies Pterodroma phaeopygia phaeopygia, we regard it as a full species as well as Pterodroma sandwichensis (Ridgway, 1884), following Browne et al. (1997: 814). The material examined from Pterodroma phaeopygia differs in some features from typical Trabeculus fuscoclypeatus. However, we do not consider that such differences justify naming a new taxon; hence we qualify the samples from Pt. phaeopygia as “ sensu lato ”.
 This is the first record of Trabeculus fuscoclypeatus from the Galápagos Islands, and a new host-louse association for Pterodroma phaeopygia. Four other species of Pterodroma are listed in Price et al. (2003: 244) as hosts of this louse species.

description: Movement enables mobile organisms to respond to local environmental conditions and is driven by a combination of external and internal factors operating at multiple scales. Here, we explored how resource distribution interacted with the internal state of organisms to drive patterns of movement. Specifically, we tracked snail movements on experimental landscapes where resource (algal biofilm) distribution varied from 0 to 100% coverage and quantified how that movement changed over a 24 h period. Resource distribution strongly affected snail movement. Trajectories were tortuous (i.e. Brownian-like) within resource patches but straighter (i.e. Lévy) in resource-free (bare) patches. The average snail speed was slower in resource patches, where snails spent most of their time. Different patterns of movement between resource and bare patches explained movement at larger spatial scales; movement was ballistic-like Lévy in resource-free landscapes, Lévy in landscapes with intermediate resource coverage and approximated Brownian in landscapes covered in resources. Our temporal analysis revealed that movement patterns changed predictably for snails that satiated their hunger and then performed other behaviours. These changes in movement patterns through time were similar across all treatments that contained resources. Thus, external and internal factors interacted to shape the inherently flexible movement of these snails.

description: The aim of this paper is to determine whether training level affects the safe use of pesticides amongst pesticide applicators of Galician greenhouse farms (Spain). The relationship between pesticide applicator training and safe use of pesticides was statistically analyzed using non-parametric tests. Results did not reveal any relationship between the training level of pesticide applicators and the implementation of good practices in pesticide use. This paper questions current training systems for pesticide application and points to the need for the implementation of methods that assess and monitor the results and added value of training to pesticide applicators’ practices.

description: Dynamo action in the Earth's outer core is expected to be controlled by a balance between pressure, Coriolis, buoyancy and Lorentz forces, with marginal contributions from inertia and viscous forces. Current numerical simulations of the geodynamo, however, operate at much larger inertia and viscosity because of computational limitations. This casts some doubt on the physical relevance of these models. Our work aims at finding dynamo models in a moderate computational regime which reproduce the leading-order force balance of the Earth. By performing a systematic parameter space survey with Ekman numbers in the range $10^{-6} \leq E \leq 10^{-4}$, we study the variations of the force balance when changing the forcing (Rayleigh number, $Ra$) and the ratio between viscous and magnetic diffusivities (magnetic Prandtl number, $Pm$). For dipole-dominated dynamos, we observe that the force balance is structurally robust throughout the investigated parameter space, exhibiting a quasi-geostrophic (QG) balance (balance between Coriolis and pressure forces) at zeroth order, followed by a first-order MAC balance between the ageostrophic Coriolis, buoyancy and Lorentz forces. At second order this balance is disturbed by contributions from inertia and viscous forces. Dynamos with a different sequence of the forces, where inertia and/or viscosity replace the Lorentz force in the first-order force balance, can only be found close to the onset of dynamo action and in the multipolar regime. Our study illustrates that most classical numerical dynamos are controlled by a QG-MAC balance, while cases where viscosity and inertia play a dominant role are the exception rather than the norm.

description: It has recently been pointed out that generic models of quantum gravity must contend with severe phenomenological constraints imposed by gravitational Cerenkov radiation, neutrino oscillations and the cosmic microwave background radiation. We show how the non-critical Liouville-string model of quantum gravity we have proposed escapes these constraints. It gives energetic particles subluminal velocities, obviating the danger of gravitational Cerenkov radiation. The effect on neutrino propagation is naturally flavour-independent, obviating any impact on oscillation phenomenology. Deviations from the expected black-body spectrum and the effects of time delays and stochastic fluctuations in the propagation of cosmic microwave background photons are negligible, as are their effects on observable spectral lines from high-redshift astrophysical objects.

description: The magnetization-density distribution in the metallic ferromagnet SrRuO$_3$ was studied by means of polarized neutron diffraction. The analyzes by multipole refinements and by the maximum entropy method consistently reveal a strong polarization of all oxygen sites carrying 30\% of the total magnetization. The spin-density distribution on the Ru site exhibits a nearly cubic shape in agreement with an almost equal occupation of $t_{2g}$ orbitals and $pd$ hybridization. The experimental analysis is well reproduced by density functional calculations. There is no qualitative change in the magnetization distribution between 2 and 200 K.

description: Urophonius granulatus group   Figure 1; table 1
 DIAGNOSIS: The four species in the granulatus group of Urophonius can be separated from other species in the genus by means of the following combination of characters. Metasomal segment I, VSM carinae distinct, usually subparallel throughout length (diverging slightly at anterior margin of segment in some species) (figs. 3A, C, D, 4A, C, D), except for U. somuncura, in which it is absent or reduced to a few granules (figs. 3B, 4B). Metasomal segment I with two or three pairs of ventral macrosetae; II and III each with three pairs of ventral macrosetae (figs. 3, 4). Telotarsal spination, leg III: 5–5/5–6; IV: 5–6/6–7. Hemispermatophore, lobe region small to medium sized; capsular concavity very well developed; area between basal lobe and external lobe concave (fig. 8A, C, E, G); internal lobe with small, bilobed apophysis disconnected from distal lamina (fig. 8B, D, F, H). Trichobothrial pattern, neobothriotaxic major Type C, with one accessory trichobothrium in V series of chela; femur with 3 trichobothria (d, i, e); patella with 19 (3 V, 2 d, i, 3 et, est, 2 em, 2 esb, and 5 eb); chela with 27 (Est, 5 Et, 5 V, Esb, 3 Eb, Dt, Db, et, est, esb, eb, dt, dst, dsb, db, ib, and it); femoral trichobothrium e situated close to a single dorsal macroseta (M1), variable with respect to macrosetae in different species (figs. 10A, 13A, 16A, 19A). Chelicera, movable finger with two well-developed subdistal teeth. Metasomal segments, ventral surfaces each with paired VL and single VM pigmentation stripes, without paired VSM stripes.

description: We investigate spherically symmetric and static gravitational fields representing black hole configurations in the framework of metric-affine gauge theories of gravity (MAG) in the presence of different matter fields. It is shown that in the triplet ansatz sector of MAG, black hole configurations in the presence of non-Abelian matter fields allow the existence of black hole hair. We analyze several cases of matter fields characterized by the presence of hair and for all of them we show the validity of the no short hair conjecture.

description: This paper provides an empirical analysis of the determinants of energy efficiency in fossil fuel electricity generation across 28 OECD countries over the period 1981-2006, with particular attention to the role played by technological development and the availability of energy efficient technologies in the market. This contribution is novel in three respects: first, empirically assess the effects of different determinants of energy efficiency, which include the input mix in electricity generation, the capacity ratio at which power plants are run, as well as the characteristics of the production technology. Second, we focus on the role of technological availability: using patent data for carefully selected innovations in fossil-fuel technologies, we build an indicator which proxies for technological developments in fuel-efficient electricity generation. Third, by formalizing the relationship between fuel efficiency and carbon intensity, we assess the impact of changes in the input mix and in technological availability on CO2 emissions in the electricity sector. Results show that input mix, capacity utilization and new investment in capacity play a significant role in increasing energy efficiency. Increasing the stock of available technologies (or stock of knowledge) is also associated with higher efficiency levels. Given the link between increased efficiency and lower CO2 emissions, we conclude that technological change has a negative and significant effect on carbon intensity, while the changing input mix affects CO2 intensity both through an increase in efficiency as well as by lowering the input-weighted emission factor.

description: This transformative agreement toolkit was developed as part of the Society Publishers Accelerating Open access and Plan S (SPA-OPS) project. Transformative agreements repurpose existing institutional spend with publishers to open content. They are promising transition models because libraries and library consortia provide the lion’s share of funding in the current publishing landscape. Publishers, consortia and institutions can use the resources in this tool kit to collect data to inform commercial offers; to draft their own transformative agreement offers, licences and contracts; and for reporting. The toolkit contains templates that stakeholders can amend and adapt to reflect aspects of their particular agreements and to suit local conditions. Please refer to the document “Model Transformative Agreement Toolkit – start here” for an overview of the toolkit and its contents. This work was conducted by Alicia Wise and Lorraine Estelle of Information Power. The SPA-OPS project was commissioned by Wellcome, UKRI, and the Association of Learned and Professional Society Publishers (ALPSP).

description: Carbon-based border tax adjustments (BTAs) have recently been proposed by some OECD countries to level the carbon playing field and target major emerging economies. This paper applies a multi-sector dynamic computable general equilibrium (CGE) model to estimate the impacts of the BTAs implemented by US and EU on China’s sectoral carbon emissions. The results indicate that BTAs will cut down export prices and transmit the effects to the whole economy, reducing sectoral output-demands from both supply side and demand side. On the supply side, sectors might substitute away from exporting toward domestic market, increasing sectoral supply; while on the demand side, the domestic income may be strikingly cut down due to the decrease in export price, decreasing sectoral demand. Furthermore, such shrinkage of demand may similarly reduce energy prices, which leads to energy substitution effect and somewhat stimulates carbon emissions. Depending on the relative strength of the output-demand effect and energy substitution effect, sectoral carbon emissions and energy demands will vary across sectors, with increasing, decreasing or moving in a different direction. These results suggest that an incentive mechanism to encourage the widespread use of environment-friendly fuels and technologies will be more effective.

 Type host: Puffinus opisthomelas Coues, 1864.
 Galápagos host: Puffinus subalaris Ridgway, 1897.
Galápagos localities: Isla Wolf; Isla Isabela.
Galápagos references: Kellogg & Kuwana (1902); Kellogg (1906); Kellogg (1908: 34); Thompson (1939: 213); Linsley & Usinger (1966).

Material examined: 3 females (2 samples, EMEC).
 Remarks: Puffinus subalaris is endemic to the Galápagos Islands. Although Dickinson (2003: 76) listed the host of this louse as Puffinus lherminieri subalaris, we regard it as a full species following Austin et al. (2004: 859). No specimen of Trabeculus was collected from five specimens of Puffinus subalaris searched for lice during the 1992 Galápagos Expedition. From the Kellogg Collection, we examined the two females reported by Kellogg & Kuwana (1902: 482), and one female of the material reported by Kellogg (1906: 320), all from Puffinus subalaris, and identified them as Trabeculus mirabilis. Price et al. (2003: 245) listed four species of Puffinus as hosts of T. mirabilis including Puffinus subalaris, but cited as “ P. lherminieri ”.
 For the original description of Giebelia mirabilis, Kellogg (1896: 138) examined “Four males and five females …”. As no lectotype has been selected yet, we herewith designate the male on Kellogg Collection slide 139 “fig’d” as the lectotype of Giebelia mirabilis, with the remaining seven specimens from Puffinus opisthomelas (2 males and 5 females on slides 139, 140a, 498a, 502a, 507a, 512a) as paralectotypes, all deposited in EMEC.
