Publisher: name: arXiv

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

subject: FOS: Physical sciences

description: We study the proximity effect of a superconductor to a normal system with fractal spectrum. We find that there is no gap in the excitation spectrum, even in the case where the underlying classical dynamics of the normal system is chaotic. An analytical expression for the distribution of the smallest excitation eigenvalue $E_g$ of the hybrid structure is obtained.On small scales it decays algebraically as ${\cal P}(E_g)\sim E_g ^{-D_0}$, where $D_0$ is the fractal dimension of the spectrum of the normal system. Our theoretical predictions are verified by numerical calculations performed for various models.

description: One of the redeeming virtues of the study of economics is that it enables its practitioners to discuss subjects about which they know very little. This paper represents a case in point. The premise of the paper rests on the presumption that aquaculture provides an additional source of aquatic life; this presumption is, of course, true by definition. The purpose of this paper is to investigate the potential of aquaculture to regulate the harvest from natural production, but more importantly the purpose is to consider the difficulties that even relatively simple tools pose for the fishery manager.
On the filling factor of emitting material in the upper atmosphere of Epsilon Eri (K2 V)
Creators: name: Sim, S. A.
name: Jordan, C.
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The emission measure distribution in the upper transition region and corona of Epsilon Eri is derived from observed emission line fluxes. Theoretical emission measure distributions are calculated assuming that the radiation losses are balanced by the net conductive flux. We discuss how the area factor of the emitting regions as a function of temperature can be derived from a comparison between these emission measure distributions. It is found that the filling factor varies from ~0.2 in the mid transition region to ~1.0 in the inner corona. The sensitivity of these results to the adopted ion fractions, the iron abundance and other parameters is discussed. The area factors found are qualitatively similar to the observed structure of the solar atmosphere, and can be used to constrain two-component models of the chromosphere. Given further observations, the method could be applied to investigate the trends in filling factors with indicators of stellar activity.

The Fokker-Planck operator at a continuous phase transition

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: I consider a physical system described by a continuous field theory and enclosed in a large but finite cubical box with periodic boundary conditions. The system is assumed to undergo a continuous phase transition at some critical point. The ϕ^4 theory that is a continuous version of the Ising model is such a system but there are many other examples corresponding to higher spin, higher symmetry etc. The eigenfunctions of the corresponding Fokker-Planck operator can be chosen, of course, to be eigenfunctions of the momentum operator. It is shown that the eigenvalues of the FP operator, corresponding to each eigenvalue q of the momentum operator, evaluated at a transition point of the finite system, accumulate at zero, when the size of the system tends to infinity. There are many reasonable ways of defining a critical temperature of a finite system, that tends to the critical temperature of the infinite system as the size of the system tends to infinity. The accumulation of eigenvalues is neither affected by the specific choice of critical temperature of the finite system nor by whether the system is below or above its upper critical dimension.

description: We analyze transcendentality for certain terms that arise in multiloop amplitudes in the low momentum expansion of the four graviton amplitude in type IIB string theory in ten dimensions, based on the constraints of supersymmetry and S--duality. This leads to several contributions that violate transcendentality beyond one loop at all orders in the low momentum expansion. We also perform a similar analysis for the five graviton amplitude, obtaining contributions that involve single--valued multiple zeta values beyond tree level.

description: Rhoptromeris nigriventris Nordlander, 1978
(Figure 5g,h)
 Diagnosis
 This species shares with  R. ru fi ventris  and R. macaronesiensis sp. nov. the lack of the anteroventral cavity of the metapleura. It can be distinguished by the pronotal foveae separated by a medial bridge, larger eyes, broader wings and higher scutellum with relatively broad scutellar plate.
 Several studied specimens exhibited a mix of diagnostic characters of both R. nigriventris and  R. ru fi ventris , and more extensive molecular studies could be useful to better elucidate the relationship between these species.
 Redescription
Compound eyes relatively large. Antennae rather long in both sexes. Male F2 enlarged, strongly curved. Female antennae with an indistinct 7-segmented club. Pronotal foveae separated by a medial bridge. Dorsal scutellar surface usually smooth, sometimes more or less strongly sculptured in the posterior half. Scutellar plate large. Anteroventral cavity of metapleura absent, posterior incision of metapleura absent. Wings relatively broad.
 Distribution
Widespread throughout Europe. Records listed here follow Fauna Europaea and Nordlander (1978), with additions by the authors. EUROPE: Bosnia, England, Finland, Germany, Italy, Poland, Spain, Sweden.
 Biology
 Specimens of Rhoptromeris nigriventris have been collected in field and forest areas. The species is probably a parasitoid of grass-inhabiting Chloropidae (Nordlander 1978).

Publisher: name: Zenodo
Year: 2025

description: Metabolic syndrome (MetS) is a group of interconnected risk factors that significantly increase the likelihood of cardiovascular diseases, type 2 diabetes, and other metabolic disorders. Among the various components of MetS, morphological changes in the heart are becoming increasingly recognized for their role in cardiovascular dysfunction. This article explores the key morphological alterations in the heart associated with MetS, including left ventricular hypertrophy, myocardial fibrosis, and changes in heart chamber dimensions. The underlying mechanisms, such as insulin resistance, chronic inflammation, and oxidative stress, contribute to these structural changes, leading to impaired cardiac function and an elevated risk of heart failure, arrhythmias, and coronary artery disease. The article further discusses the implications of these changes for cardiovascular health, emphasizing the importance of early detection and intervention. Finally, it outlines potential treatment strategies aimed at preventing or reversing these cardiac alterations to improve long-term cardiovascular outcomes in individuals with MetS.

description: We study the time evolution of freely rolling moduli in the context of M-theory on a G_2 manifold. This free evolution approximates the correct dynamics of the system at sufficiently large values of the moduli when effects from non-perturbative potentials and flux are negligible. Moduli fall into two classes, namely bulk moduli and blow-up moduli. We obtain a number of non-trivial solutions for the time-evolution of these moduli. As a generic feature, we find the blow-up moduli always expand asymptotically at early and late time.

Rhoptromeris rufiventris

description: Rhoptromeris rufiventris (Giraud, 1860)
(Figure 5i)
 Diagnosis
 Body brown, anteroventral portion of metasoma with a reddish tinge, this colour more pronounced on females. The species is most similar to R. macaronesiensis sp. nov., from which it can be distinguished by the absence of the posterior incision of the metapleura.  R. ru fi ventris  can further be separated from R. nigriventris by the pronotal fovea fused medially into a continuous furrow (separated by a medial bridge in R nigriventris), narrow scutellar fovea and very short scutellum.
 Several studied specimens exhibited a mix of diagnostic characters of R. nigriventris and  R. ru fi ventris , and more extensive molecular studies could be useful to better elucidate the relationship between both species.
 Redescription
Female: Compound eyes small. Pronotal fovea fused medially forming a transverse furrow. Antennae approximately 0.7 times body length, club 7-segmented. Dorsal scutellar surface smooth, scutellar plate narrow. Scutellum short, sloping steeply posteriorly after the scutellar plate. Anteroventral cavity of metapleura absent, posterior incision of metapleura absent. Wings narrow.
Male unknown.
 Distribution
Widespread throughout Europe. Records listed here follow Fauna Europaea and Nordlander (1978), with additions by the present authors. EUROPE: Austria, Spain and Sweden.
 Biology
  Rhoptromeris ru fi ventris  has been collected by sweeping on lawns, and at least one specimen was captured in a pitfall trap placed in an oat field (Nordlander 1978). Probably a parasitoid of grass-inhabiting Chloropidae (Nordlander 1978).

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The CERN Axion Solar Telescope (CAST) searches for axions coming from photon to axion conversion in the sun's core, as stated by the Primakoff effect. Axions arise in particle physics as a consequence of the breaking of Peccei-Quinn symmetry which has been introduced as a solution to the strong CP problem. As cosmological axions they are candidates for at least some part of cold Dark Matter.They are also expected to be produced copiously in stellar interiors with energies as high as the thermal photons undergoing photon to axion conversion. In our sun the axion energy spectrum peaks at about 4.4 keV, extending up to 10 keV. CAST collected preliminary data in 2002 and data taking with its full capability will start in the beginning of 2003.

description: This study examined consumer’s willingness to pay for food safety attributes in bread in Lagos metropolis. It empirically analyzed the factors driving willingness to pay for improved bread and the effect of attributes on willingness to pay and mean willingness to pay for improved bread. The data for the study using a well-structured questionnaire containing Choice Experiment (CE) questions for eliciting willingness to pay was collected from 150 respondents using a two-stage random sampling technique. Data analysis was carried out using descriptive statistics and the Conditional logit regression model. Empirical results reveal that price and the non-monetary attributes namely, bromate label, certification, nutritional label, flavor and texture were all significant in explaining consumer’s choices. The study suggests that government and producers should promote strict adherence to bromate free and nutritional labels, since the result shows that consumers’ willingness to pay is higher than the status quo with respect to this attributes.
Efficient QP-ADMM Decoder for Binary LDPC Codes and Its Performance Analysis

description: This paper presents an efficient quadratic programming (QP) decoder via the alternating direction method of multipliers (ADMM) technique, called QP-ADMM, for binary low-density parity-check (LDPC) codes. Its main contents are as follows: first, we relax maximum likelihood (ML) decoding problem to a non-convex quadratic program. Then, we develop an ADMM solving algorithm for the formulated non-convex QP decoding model. In the proposed QP-ADMM decoder, complex Euclidean projections onto the check polytope are eliminated and variables in each updated step can be solved analytically in parallel. Moreover, it is proved that the proposed ADMM algorithm converges to a stationary point of the non-convex QP problem under the assumption of sequence convergence. We also verify that the proposed decoder satisfies the favorable property of the all-zeros assumption. Furthermore, by exploiting the inside structures of the QP model, the complexity of the proposed algorithm in each iteration is shown to be linear in terms of LDPC code length. Simulation results demonstrate the effectiveness of the proposed QP-ADMM decoder.

description: The paper is on Cost-Benefit Analysis of certified cocoa production in Ondo state.Data were collected by purposively choosing three local government areas noted for certified cocoa production, namely Idanre, Ile oluji and Owo local government areas of the state. Simple random sampling technique was used to select thirty certified cocoa farmers from Idanre, twenty certified cocoa farmers from Ile oluji/Oke-igbo and ten certified cocoa farmers from Owo local government areas of the state making a total of sixty respondents in all. The data collected were analyzed using descriptive statistics, profitability analysis, gross margin analysis and cost benefit analysis.The profitability analysis, gross margin analysis and cost benefit analysis showed that conventional cocoa production is profitable with profit, GM, NPV, BCR and IRR of N5,713,329 N11,062,329 N428,306.3, 1.04 and 31.31% respectively. It was also revealed that certified cocoa production was more profitable than conventional cocoa production having profit, GM, NPV, BCR and IRR of N14, 889,098, N20,238,090, N5,253,237,1.45 and 59.64% respectively.The major identified constraints in certified cocoa production were: inadequate resources to finance their farming operations and unavailability of inputs. Recommendations from the study include among others: provision of inputs at subsidized rate to the farmers at reasonable and affordable interest rates, need for effective monitoring and evaluation team for certified cocoa farmers in order to reduce the share of certified cocoa sold into conventional channel, more awareness and sensitization programmes on cocoa certification so that more farmers and non-governmental organizations will be involved.

description: A method for embedding graphs in Euclidean space is suggested. The method connects nodes to their geographically closest neighbors and economizes on the total physical length of links. The topological and geometrical properties of scale-free networks embedded by the suggested algorithm are studied both analytically and through simulations. Our findings indicate dramatic changes in the embedded networks, in comparison to their off-lattice counterparts, and call into question the applicability of off-lattice scale-free models to realistic, everyday-life networks.

 Redescription
Compound eyes relatively large. Male antennae elongate, F1 and F2 lighter than remaining flagellomeres. Female antennae short, pre club flagellomeres light brown to brown, club darker, distinct, 6-segmented. Pronotal fovea fused medially forming a transverse groove. Dorsal scutellar surface costulate, scutellar plate broad. Anteroventral cavity of metapleura present, posterior incision of metapleura absent. Wings relatively broad, marginal with vein Rs longer than 2r.

description: Cassava, has received much research on improved varietal development in Ghana. The National Agricultural Research Systems (NARS) have released about 24 improved cassava varieties since 1993, which are high yielding, disease and pest resistant and early maturing. However, adoption by smallholder farmers is very low leading to low outputs and low incomes. Adoption could be improved with greater understanding of farmers’ cassava variety attributes preferences. Using stated preference technique, specifically, choice experiment applied across 450 farm households, we evaluated farmers preferences for cassava variety attributes in Ghana and identified farm household-specific and institutional factors that governed the preferences. The empirical results showed that in-soil storage (longevity) and disease resistance are important attributes for farmers' choice of cassava varieties. Farmers have lower utility towards high productivity. Farmers are willing to forgo some extra incomes and yields in order to obtain a more disease and pest resistant varieties and increased longevity of matured roots in the soil. This implies that until market chains are expanded the introduction of new and improved varieties would not contribute significantly towards utilities. Among other things, age, gender, extension and years of farming experience, are the major factors causing household heterogeneity of cassava varieties preferences. Based on our experimental results, we derived important policy implications for breeding priority setting and cassava varieties adoption.

description: Although PELIS was established mainly to promote forest plantation development through enhancing forest establishment and the survival of plantation trees, it has also provided other significant benefits such as making available arable land for the landless and contributing to food production. This study investigated the contribution of PELIS towards alleviating food insecurity and landlessness. Selected forest zones, where PELIS is practiced were used. Communities residing near the forests were served with questionnaires to document arable lands given and food produced. Results showed that PELIS provided an annual average of upto 2,000 hectares of arable land to the landless, which contributed an annual total average of upto 3 million bags of potatoes from the forest zones investigated. This study recommends that management considers establishing PELIS in the other remaining forest zones in order to provide more arable land and consequently increase food production.
Coherent interaction of laser pulses in a resonant optically dense extended medium under the regime of strong field-matter coupling

description: Nonstationary pump-probe interaction between short laser pulses propagating in a resonant optically dense coherent medium is considered. A special attention is paid to the case, where the density of two-level particles is high enough that a considerable part of the energy of relatively weak external laser-fields can be coherently absorbed and reemitted by the medium. Thus, the field of medium reaction plays a key role in the interaction processes, which leads to the collective behavior of an atomic ensemble in the strongly coupled light-matter system. Such behavior results in the fast excitation interchanges between the field and a medium in the form of the optical ringing, which is analogous to polariton beating in the solid-state optics. This collective oscillating response, which can be treated as successive beats between light wave-packets of different group velocities, is shown to significantly affect propagation and amplification of the probe field under its nonlinear interaction with a nearly copropagating pump pulse. Depending on the probe-pump time delay, the probe transmission spectra show the appearance of either specific doublet or coherent dip. The widths of these features are determined by the density-dependent field-matter coupling coefficient and increase during the propagation. Besides that, the widths of the coherent features, which appear close to the resonance in the broadband probe-spectrum, exceed the absorption-line width, since, under the strong-coupling regime, the frequency of the optical ringing exceeds the rate of incoherent relaxation. Contrary to the stationary strong-field effects, the density- and coordinate-dependent transmission spectra of the probe manifest the importance of the collective oscillations and cannot be obtained in the framework of the single-atom model.

description: We investigate the dependence of stellar disc scale lengths on environment for a sample of Sloan Digital Sky Survey Data Release 7 galaxies with published photometric bulge-disc decompositions. We compare disc scale lengths at fixed bulge mass for galaxies in an isolated field environment to galaxies in X-ray rich and X-ray poor groups. At low bulge mass, stellar disc scale lengths in X-ray rich groups are smaller compared to discs in both X-ray poor groups and in isolated field environments. This decrease in disc scale length is largely independent of halo mass, though shows some dependence on group-centric distance. We also find that stellar disc scale lengths are smaller in X-ray rich environments for a subset of star-forming galaxies and for galaxies of different morphological types. We note that disc scale lengths of low mass galaxies are known to have large systematic uncertainties, however we focus on differences between samples with the same measurement biases. Our results show that stellar disc scale lengths depend on X-ray brightness, a tracer of IGM density, suggesting a role for hydrodynamic processes such as ram-pressure stripping and/or starvation.

Saphonecrus tianmushanus Wang & Chen in Wang et al. (2010). Biologia 65 (6): 1037. Type material: ZAFU according to Wang et al. (2010). Synonymized by Pujade-Villar et al. (2017): 62.
Material examined (6♂ & 2♀). Newly reared material deposited in UB with the following data: KOR: 36, Dong- baekdongsan, Jeju Island (South Korea), Ex. asexual galls of Neuroterus nr hakonensis, Q. glauca, (09.v.2019) Roca-Cusachs leg.
Distribution. Japan (Honshű and Kyűshű islands) (Wachi et al. 2011; Melika et al. 2012); Taiwan (Nantou, Taichung and Hsinchu counties) (Melika et al. 2012); and mainland China (Zhejiang and Fujian provinces) (Wang et al. 2010; Pujade-Villar et al. 2017). First record of this species for South Korea (this paper).
Biology. Reared from undescribed leaf galls on Quercus glauca Thunb. (= Q. globosa (Lin & Liu) Liao) (Wachi et al. 2011; Melika et al. 2012). The new material included in this paper was reared from leaf galls of Neuroterus nr hakonensis (asexual form) on Q. glauca.
Remarks. Neuroterus hakonensis is treated as a gall inducer of Q. acutissima (Pénzes et al. 2018). The galls of the species that are treated here as Neuroterus nr. hakonensis are morphologically identical to those of the asexual generation of N. hakonensis; however, no adults of the gall inducer were obtained from the collected galls. Even though the identity of these galls needs to be confirmed, the original material of S. shirakashii was obtained from presumably undescribed leaf galls on Q. glauca, which matches well with the galls from South Korea presented here.

description: We present the Hamburg/RASS Catalogue (HRC) of optical identifications of X-ray sources at high-galactic latitude. The HRC includes all X-ray sources from the ROSAT Bright Source Catalogue (RASS-BSC) with galactic latitude |b| >= 30 degr and declination delta >= 0 degr. In this part of the sky covering ~10 000 deg^2 the RASS-BSC contains 5341 X-ray sources. For the optical identification we used blue Schmidt prism and direct plates taken for the northern hemisphere Hamburg Quasar Survey (HQS) which are now available in digitized form. The limiting magnitudes are 18.5 and 20, respectively. For 82% of the selected RASS-BSC an identification could be given. For the rest either no counterpart was visible in the error circle or a plausible identification was not possible. With ~42% AGN represent the largest group of X-ray emitters, \~31% have a stellar counterpart, whereas galaxies and cluster of galaxies comprise only ~4% and ~5%, respectively. In ~3% of the RASS-BSC sources no object was visible on our blue direct plates within 40 arcsec around the X-ray source position. The catalogue is used as a source for the selection of (nearly) complete samples of the various classes of X-ray emitters.

description: A adoção de métodos alternativos ou adequados na solução de conflitos tem sido estimulada visando a redução do número de processos. Também pode obter maior qualidade nos julgamentos, possibilitando o acesso à justiça, em prazo razoável, àqueles casos em que as partes não possuem condições ou não podem resolver seus problemas mediante autocomposição. Conforme dados do CNJ, no final de 2017 o Poder Judiciário contava com um acervo de 80,1 milhões de processos em andamento, com uma taxa de ampliação média anual de 4%, o que demonstra a necessidade de abertura de novas portas (sistema multiportas) para a resolução das controvérsias além da sentença, que nem sempre trará melhora nas relações entre as partes, até porque a demora na tramitação processual, cuja média na justiça comum de primeiro grau é de três anos e sete meses, propicia um elevado custo econômico e emocional aos envolvidos.

description: An increasing number of choice experiment studies has shown that not all respondents consider all attributes when choosing their preferred alternative in the presented choice sets. Not accounting for this so-called ‘attribute non-attendance’ will lead to bias parameter estimates, and can hence increase or reduce estimates of willingness to pay. In this study, three aspects of attribute non-attendance are investigated. First, scale heterogeneity models are specified to test whether attribute attendance affects the variance of the error term. Second, the concordance between stated non-attendance and inferred non-attendance is assessed by comparing answers to supplementary questions with results from equality constrained latent class models. Finally the impacts of varying attribute descriptions or attribute levels on attendance is analysed. Results show that model fit is significantly improved when attribute non-attendance is taken into account, that but welfare estimates are not significantly different. The scale heterogeneity models reveal significant individual heterogeneity in scale, which decreases when incorporating ANA in the model specification. There is little overlap between stated and inferred non-attendance. Finally, describing a rare species attribute in terms of “number of species lost” attracts more attention to that attribute compared to “number of species present”, and that using a higher price vector may reduce attendance to the cost attribute.

description: This study used a parametric frontier approach to analyze technical, allocative and economic efficiency of smallholder rice farmers. It further explored the factors that influence the efficiency levels of the rice farmers. The study used a trans-log stochastic production function to analyze the technical efficiency. It used the trans-log cost frontier to analyze the economic efficiency. Results from these efficiencies led to the derivation of the allocative efficiency levels. It further used the inefficiency model to analyze the factors underlying efficiency differentials among the sampled farming households. Results revealed an average technical, allocative and economic efficiency levels of 65%, 59% and 53% respectively. This suggests that farmers have a rice yield potential of 35% to be exploited. The average economic efficiency level entails that farmers can raise their profitability or rice production by 47% by adjusting input use. Soil fertility status, access to credit, household size and farmers experience were the factors that influence the efficiency levels of smallholder rice farmers. It is thus recommended that for improved efficiency levels there is need for better policies and strategies that address input and output markets. Furthermore, farmer groups or associations can play a great role in ensuring that farmers get relevant technical advice, credit access as well as learn and share knowledge from each other.

description: Herein, a novel C=O–NOH-contained compound was synthesized and used in the extraction and recovery of copper from sulfate solution. Dodecyl phenyl ethyl hydroxamic acid (DPEHA) exhibited high selectivity to Cu(II) over the competing ions, and the separation factors (β) obtained were βCu/Zn = 227.370, βCu/Co = 199.094, βCu/Ni = 188.889, respectively. The separation effect was stronger than that of 2-hydroxy-5-nonyl acetophenone oxime. Meanwhile, extraction capacity of 0.10 g Cu(II) per gram DPEHA was reached, and the extracted Cu(II) can be stripped effectively. The investigation of extraction mechanism revealed that O atoms in C=O and O-H groups of DPEHA operate as active sites, which could powerfully chelate with Cu(II) by forming stable five-membered rings. The high copper extraction efficiency and selectivity associated with a simple synthesis of DPEHA make it to serve as the potential selective Cu(II) extractant, which also provide a novel insight for the research and development of economical Cu(II) extractants.

description: The East Usambaras, located in northeast Tanzania, are a tropical biodiversity hotspot where unsustainable agricultural management practices pose threats to landscape conservation and development objectives. Promoting Sustainable Agricultural Intensification (SAI) would improve long term productivity and reduce pressures on forest reserves. This study assesses adoption of soil fertility investments using farm and household data to evaluate profitability and feasibility of scaling up SAI. A cross sectional design and mixed methods approach were used to compare the profitability of common farming systems and the effects of various household characteristics on adoption of soil improvement practices. Focus groups were used to classify three common farming systems and a fourth model was developed to estimate the relative profitability of incorporating fallow, organic inputs and non-timber forest product activities. Next, household surveys (144) and a logit regression analysis were used to evaluate the effects of socioeconomic characteristics, physical and financial assets, tenure risk and plot specific attributes on the soil fertility investments specified in the model. Findings showed that the SAI model was financially competitive but would likely incur opportunity costs to labor. The logit results showed that marital status, household size, remittances, credit access, and tenure security significantly influenced adoption. Perceived fertility and distance to plots were also significant at plot level. The potential for developing synergies to promote and scale up SAI require stronger policy and institutional support.

description: We present Solythesis, a source to source Solidity compiler which takes a smart contract code and a user specified invariant as the input and produces an instrumented contract that rejects all transactions that violate the invariant. The design of Solythesis is driven by our observation that the consensus protocol and the storage layer are the primary and the secondary performance bottlenecks of Ethereum, respectively. Solythesis operates with our novel delta update and delta check techniques to minimize the overhead caused by the instrumented storage access statements. Our experimental results validate our hypothesis that the overhead of runtime validation, which is often too expensive for other domains, is in fact negligible for smart contracts. The CPU overhead of Solythesis is only 0.12% on average for our 23 benchmark contracts.
