description: The migration of planetary cores embedded in a protoplanetary disk is an important mechanism within planet-formation theory, relevant for the architecture of planetary systems. Consequently, planet migration is actively discussed, yet often results of independent theoretical or numerical studies are unconstrained due to the lack of observational diagnostics designed in light of planet migration. In this work we follow the idea of inferring the migration behavior of embedded planets by means of the characteristic radial structures that they imprint in the disk's dust density distribution. We run hydrodynamical multifluid simulations of gas and several dust species in a locally isothermal $α$-disk in the low-viscosity regime ($α=10^{-5}$) and investigate the obtained dust structures. In this framework, a planet of roughly Neptune mass can create three (or more) rings in which dust accumulates. We find that the relative spacing of these rings depends on the planet's migration speed and direction. By performing subsequent radiative transfer calculations and image synthesis we show that - always under the condition of a near-inviscid disk - different migration scenarios are, in principle, distinguishable by long-baseline, state-of-the-art ALMA observations.

description: In January 2020, the Government of Belize enacted an Implementation Strategy and Action Plan to phase-out single-use plastics and to transition to products like bioplastics. This work investigated the environmental effects of using alternative waste management techniques to manage polylactic acid biopolymer (PLA) waste by using life cycle assessment (LCA). The following treatment options were compared: landfill, landfill expansion, cogeneration, and anaerobic digestion. The landfill and landfill expansion processes both had a global warming potential of 0.01 kg of CO2 eq. per kg of PLA waste managed compared to the cogeneration and anaerobic digestion processes -0.03 and -0.06 kg of CO2 eq. per kg of PLA respectively. This difference was due to offsets produced by the cogeneration and anaerobic digestion systems. Additionally, it was shown that construction material requirements of the waste management systems often attribute less than 15% of total burdens to environmental impacts. Through uncertainty and sensitivity analysis it was shown that higher gas capture efficiencies in landfills and higher electrical efficiencies in cogeneration and anaerobic digestion, should be targeted to minimize GWP. Effective use of developed LCA models can assist Belize with strategies for eliminating petroleum single-use plastic and provide waste management strategies to help inform decision makers.

description: On the 13th of May 2002, supernova 2002cv was discovered using a near-infrared camera working at the AZT-24 1.1m telescope at Campo Imperatore (AQ-Italy). After the infrared detection a simultaneous photometric follow-up was started at optical wavelengths. The preliminary results confirm a heavily obscured object with a V-K color not lower than 6 magnitudes, making SN 2002cv the most reddened supernova ever observed. This finding, along with the recent discovery of another obscured supernova, suggests a critical revision of the rates known to date. The estimate of the visual extinction and the light curves are provided here. These latter indicate that our SN 2002cv observations are the earliest available for a type-Ia supernova at IR wavelengths.

description: Experimental support is found for the multiband model of the superconductivity in the recently discovered system MgB2 with the transition temperature Tc = 39 K. By means of Andreev reflection evidence is obtained for two distinct superconducting energy gaps. The sizes of the two gaps (Delta_S = 2.8 meV and Delta_L = 7 meV) are respectively smaller and larger than the expected weak coupling value. Due to the temperature smearing of the spectra the two gaps are hardly distinguishable at elevated temperatures but when a magnetic field is applied the presence of two gaps can be demonstrated close to the bulk T_c in the raw data.

description: In this Letter, we study black hole area quantization in the context of gravitational wave physics. It was recently argued that black hole area quantization could be a mechanism to produce so-called echoes as well as characteristic absorption lines in gravitational wave observations of merging black holes. One can match the spontaneous decay of these quantum black holes to Hawking radiation calculations. Using some assumptions, one can then estimate the natural widths of these states. As can be seen from a classical paper by Bekenstein and Mukhanov, the ratio between width and spacing of nonspinning black hole states approaches a small constant, which seems to confirm the claim. However, we find that, including the effect of black hole spin, the natural widths increase. To properly address any claim about astrophysical black holes, one should examine the spinning case, as real black holes spin. Thus, the word spinning is key to the question of whether or not black holes should have an observable spectrum in nature. Our results suggest that it should be possible to distinguish between any scenarios for which the answer to this question is yes. However, for all of the commonly discussed scenarios, our answer is almost certainly no.

description: Within the context of loop quantum gravity there are several operators which measure geometry quantities. This work examines two of these operators, volume and angle, to study quantum geometry at a single spin network vertex - ``an atom of geometry.'' Several aspects of the angle operator are examined in detail including minimum angles, level spacing, and the distribution of angles. The high spin limit of the volume operator is also studied for monochromatic vertices. The results show that demands of the correct scaling relations between area and volume and requirements of the expected behavior of angles in three dimensional flat space require high-valence vertices with total spins of approximately 10^20.

description: It is generally accepted that the four major (Galilean) satellites formed out of the gas disk that accompanied Jupiter's formation. However, understanding the specifics of the formation process is challenging as both small particles (pebbles) as well as the satellites are subject to fast migration processes. Here, we hypothesize a new scenario for the origin of the Galilean system, based on the capture of several planetesimal seeds and subsequent slow accretion of pebbles. To halt migration, we invoke an inner disk truncation radius, and other parameters are tuned for the model to match physical, dynamical, compositional, and structural constraints. In our scenario it is natural that Ganymede's mass is determined by pebble isolation. Our slow-pebble-accretion scenario then reproduces the following characteristics: (1) the mass of all the Galilean satellites; (2) the orbits of Io, Europa, and Ganymede captured in mutual 2:1 mean motion resonances; (3) the ice mass fractions of all the Galilean satellites; (4) the unique ice-rock partially differentiated Callisto and the complete differentiation of the other satellites. Our scenario is unique to simultaneously reproduce these disparate properties.

F-Term Hybrid Inflation, the η-problem and Extra Dimensions

description: F-term hybrid inflation models in the context of supergravity generically have corrections to the inflaton mass squared of the order of H^{2} (the η-problem). In addition they have a problem with large deviations of the spectrum of density perturbations from scale-invariance due to non-renormalizable corrections to the superpotential. Here we show that an increase of the expansion rate at large energy densities relative to that in conventional d=4 cosmology, as suggested by the single brane Randall-Sundrum scenario with an uncompactified extra dimension, can naturally solve the ηproblem. This requires that the d=5 Planck mass satisfies M_{5} < 10^{16} GeV. In addition, the scale-invariance of the density perturbation spectrum can be generally protected from Planck-suppressed superpotential corrections if M_{5} < 10^{10} \GeV

description: This study documents how participants in an all-female youth sport organization negotiate oppositional discourses of identity. Employing Fairhurst and Putnam’s (2019) integrative method of organizational discourse analysis, the findings revealed hegemonic and alternative discourses related to gender (i.e., boys and girls are different; boys and girls are the same), which influenced how participants negotiated a nested feminine-athletic identity and nested identity discourses. Finally, this study offers a typology for how members negotiated oppositional nested and higher-order identities through (a) fleeing, (b) challenging, (c) constricting, and (d) expanding. Practical implications for how these oppositional discourses affect participation in life enrichment groups are discussed.

description: In this work, we discuss the way in which electric and magnetic dipole resonances arising in the optical scattering spectrum of non-absorbing dielectric nanospheres can be accurately approximated by means of simple explicit expressions that depend on sphere's radius, incident wavelength and relative refractive index. We find such expressions to hold not only for high but also for moderate refractive-index values, thus complementing the results reported in previous studies.

Separating cosmic shear from intrinsic galaxy alignments: correlation function tomography

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: During the past few years, secure detections of cosmic shear have been obtained, manifest in the correlation of the observed ellipticities of galaxies. Constraints have already been placed on cosmological parameters, such as the normalisation of the matter power spectrum sigma_8. One possible systematic contaminant of the lensing correlation signal arises from intrinsic galaxy alignment, which is still poorly constrained. Unlike lensing, intrinsic correlations only pertain to galaxies with small physical separations, the correlation length being a few Mpc. We present a new method that harnesses this property, and isolates the lensing and intrinsic components of the galaxy ellipticity correlation function using measurements between different redshift slices. The observed signal is approximated by a set of template functions, making no strong assumptions about the amplitude or correlation length of any intrinsic alignment. We also show that the near-degeneracy between the matter density parameter Omega_m and sigma_8 can be lifted using correlation function tomography, even in the presence of an intrinsic alignment signal.

description: The use of inoculants is a critical strategy in legume production. In Zambia, inoculants are particularly used for the production of non-promiscuous genotypes of soya beans, but rarely for cowpeas and groundnuts. This study evaluated the response of soya beans, cowpeas and groundnuts to Biofix legume inoculants. Seeds were inoculated at the recommended or double the recommended rate at planting. Plants were grown under greenhouse conditions in a Completely Randomized Design for 7 weeks. Control, non-inoculated seeds were also planted and plants grown under the same conditions. At 7 weeks, nodule number and fresh weight per plant, nodule effectiveness (pinkness/redness), and above ground biomass were determined. Biologically fixed nitrogen was determined using the Nitrogen Difference Method. Nodule number and fresh weight per plant were higher at the recommended rate of Biofix application for soya beans and at both rates for groundnuts, while there was no effect on nodule fresh weight at either rate in cowpeas. All representative nodules assessed were effective. There was no significant benefit in inoculating seeds of the three legumes with Biofix on above ground biomass and biological nitrogen fixation. These results could suggest that possibly, the introduced strains though with a stronger nodulation competitiveness, were not as effective at fixing nitrogen as the indigenous strains in the soils in which soya beans, cowpeas and groundnuts have been repeatedly grown before. This could be an indication that sufficient and appropriate effective strains are already present in this soil. In general, the results suggest that to obtain the full benefits of biological nitrogen fixation, legume growers need to be provided with the correct inoculant, where required. Further work under field conditions is recommended to confirm these findings.

description: Recent advances in chemical analytics techniques such as Liquid Chromatography-Mass Spectrometry (LC-MS), Gas Chromatography (GC)-MS and others allow measurements of low concentrations of thousands of metabolites in blood and other tissues. However, such high-throughput measurements are prone to batch effects and drifts, resulting in high coefficients of variation (CVs) for a significant fraction of measured metabolites. As much as 40% of metabolites may be discarded because of high CVs. We assume that in a well-designed metabolomics experiment relative intensity versus “run order” (i.e. the order in which samples are processed) should be independent and identically distributed, i.e. follow properties of white noise. We developed a method called batch and drift correction method by White Noise Normalization (WiNNbeta) to correct individual metabolites for batch effects and drifts. This method tests for white noise properties to identify metabolites in need of correction and corrects them by using fine-tuned splines. To test the method’s performance we applied WiNNbeta to LC-MS data from our metabolomic studies and computed CVs before and after WiNNbeta correction in quality control samples (human pooled plasma). In our tests, WiNNbeta increased the percent of metabolites with CVs less than .2 from 33% to 40%. Three metabolites were also measured by CLIA-lab using traditional assays. Correlations between CLIA-lab and LC-MS measurements corrected by WiNNbeta improved for all three metabolites. WiNNbeta can be applied to a wide range of omic measurements, it does not rely on quality control samples and filters out flat batch effects and drifts conservatively when appropriate.

description: Building on the symbiotic sustainability model, this study investigated how offline collaboration networks are related to organizations’ representational networks on social media. We analyzed survey data from disaster risk reduction organizations in North America, Europe, and Asia-Pacific regions, along with these organizations’ representational networks on Facebook (N = 108) and Twitter (N = 96). Results showed that diverse offline collaboration networks are positively related to diverse representational tie building on Facebook via organizations’ sense of mutuality. By contrast, homogeneous offline collaboration networks are positively related to diverse representational tie building on Twitter via mutuality and openness to collaboration. This study contributes to research on interorganizational networks and social media, particularly concerning the offline–online connection in the field of interorganizational communication.

Non-communicable diseases

description: Background Europe’s healthcare systems face a triple burden: the rise of non-communicable diseases (NCDs), an aging population, and a shortage of healthcare professionals. NCDs, the leading causes of death, disproportionately affect older adults, placing significant pressure on healthcare services. By 2050, nearly 30% of Europe’s population will be aged 65 or older, up from 20% in 2023. These challenges demand urgent solutions to sustain healthcare systems. Patient-facing digital health technologies (DHTs), such as Digital Diagnostics and Digital Therapeutics, offer promising tools to address this burden by empowering patient self-management, reducing strain on healthcare professionals, and enhancing system efficiency. Despite their potential, the scaling and adoption of DHTs remain limited. This study investigates: (RQ1) What key factors drive success across different patient-facing DHT categories? and (RQ2) How can companies implement these factors? Methods Following COREQ guidelines, we conducted semi-structured interviews with 29 executives and founders of European DHT companies targeting NCDs. Participants were identified using PitchBook, focusing on revenue-generating companies with over 20 employees. Virtual interviews were conducted in English between May and September 2024, lasting an average of 28 minutes (range: 21–40). Data saturation determined the sample size. Thematic analysis was performed, with two researchers independently coding the data to ensure reliability. Success factors were categorized as internal (e.g., employees) or external (e.g., partnerships). Ethical approval was obtained, and data was anonymized. Results We identified 19 success factors for scaling patient-facing DHTs. Health & Wellness companies prioritized business model flexibility (80%), while Digital Therapeutics relied on regulatory compliance (100%). Validation of health impact was critical across categories, emphasized by all respondents in Digital Diagnostics and Digital Therapeutics. Other key factors included customer awareness, strategic partnerships, and investor alignment, highlighting the importance of tailored growth strategies.
Conclusion This study provides a structured framework for scaling patient-facing DHTs, emphasizing category-specific strategies aligned with operational, regulatory, and consumer demands. It offers actionable guidance for founders and executives to allocate resources effectively and adapt to diverse market contexts. By addressing the unique challenges of scaling DHTs, this work contributes to advancing digital health research and improving healthcare system resilience.

description: Fodder is continuously cultivated in coastal area of Salalah and Batinah region of Sultanate of Oman. However, this created a negative impact on the overall agriculture system and producti­on. The government authority stopped the cultivation of Rhodes grass in coastal area and support farmers with incentive systems in order to increase fodder production investment at Najed area. Due to irrigation water policy regulations, new technical solutions required, underground water availability, fodder investors have little data to help in making investment decisions. In addition, fodder production investments are characterized by much uncertainty due to the nature of the desert farming which is relying on many factors that cannot be controlled. In this paper a dynamic evaluation model was formed and developed as a method of analyzing the economic feasibility of fodder cultivation investment project with regard to project profitability under risk environment. Economic feasibility of the investment is evaluated through calculation of the Net Present Value and IRR by using Monte Carlo Simulation models. Our objective is to formulate a dynamic programming simulation model for the investment decision with incorporating this uncertainty in a probabilistic manner. Our simulation model result shows that the dynamic models are able to help investors and policy makers in taking optimum investment decision. Taking the risk into account leads to a significant decrease of the economic attractiveness of stakeholders and more Government support is needed to achieve water policy objectives and project sustainability at new developed area at Najed.

description: We derive a relativistically covariant (although not manifestly so) equation for the distribution function of particles accelerated at shocks, which applies also to extremely relativistic shocks, and arbitrarily anisotropic particle distributions. The theory is formulated for arbitrary pitch angle scattering, and reduces to the well--known case for small angle scatterings via a Fokker--Planck approximation. The boundary conditions for the problem are completely reformulated introducing a physically motivated Green's function; the new formulation allows derivation of the particle spectrum both close and far away from the injection energy in an exact way, while it can be shown to reduce to a power--law at large particle energies. The particle spectral index is also recovered in a novel way. Contact is made with the Newtonian treatment.

description: Motivated by the recent hints of lepton flavor universality violation observed in semileptonic $B$ decays, we analyze how to test flavor and helicity structures of the corresponding amplitudes in view of future data. We show that the general assumption that such non-standard effects are controlled by a $U(2)_q \times U(2)_\ell$ flavor symmetry, minimally broken as in the Standard Model Yukawa sector, leads to stringent predictions on leptonic and semileptonic $B$ decays. Future measurements of $R_{D^{(*)}}$, $R_{K^{(*)}}$, ${\mathcal B}(\bar B_{c,u}\to \ell \bar ν)$, ${\mathcal B}(\bar B \to π\ell \barν)$, ${\mathcal B}(B \to π\ell \bar\ell)$, ${\mathcal B}(B_{s,d}\to\ell\bar\ell^{(\prime)})$, as well as various polarization asymmetries in $\bar B\to D^{(*)} τ\bar ν$ decays, will allow to prove or falsify this general hypothesis independently of its dynamical origin.

description: The literature has advocated the use of a clear and unambiguous label to inform adolescents of advertisements on social media. In this study, we introduce a norm-based label and determine its effects. In a series of three studies, we test a label that triggers the bandwagon heuristic (i.e., “your friends know this is sponsored”) and compare its effectiveness to a traditional label (i.e., “sponsored”) in a social network. The results reveal the normative label as more effective in activating adolescents' persuasion knowledge (Studies 1 and 2) and in triggering adolescents to select stricter ad settings (Study 3). In all studies, descriptive norms operate as the mediator. Based on these results, we discuss existing theories in light of social media.

description: Microbiome research is a growing, data-driven field within the life sciences. While policies exist for sharing microbiome sequence data and using standardized metadata schemes, compliance among researchers varies. To promote open research data best practices in the microbiome research community, we (1) propose two tiered badge systems to evaluate data/metadata sharing compliance, and (2) showcase an automated evaluation tool to determine adherence to data reporting standards in publications with amplicon and metagenome sequence data. In a systematic evaluation of publications (n ~ 3000) spanning human gut microbiome research, we found that nearly half of publications do not meet minimum standards for sequence data availability. Moreover, poor standardization of metadata creates a high barrier to harmonization and cross-study comparison. Using this badge system and evaluation tool, our proof-of-concept work exposes (i) the ineffectiveness of sequence data availability statements, and (ii) the lack of consistent metadata standards for annotating microbial data. In this Perspective, we highlight the need for improved practices and infrastructure that reduce barriers to data submission and maximize reproducibility in microbiome research. We anticipate our tiered badge framework will promote dialogue regarding data sharing practices and facilitate microbiome data reuse, supporting best practices that make microbiome data FAIR.

description: arcass and organs characteristics of two breeds and sexes of poultry which include Duck and Guinea fowl (GF) were investigated. A total of twenty four matured birds with twelve from each breed were used for this study in a 2 × 2 (Breed × Sex) factorial arrangement in a completely randomized design. The birds were slaughtered in batches of four properly bled, defeathered and dressed, the carcasses and organs weighed. The birds carcasses were chilled at 4 ºC for 24hrs prior to fabrication into primal cuts. The results showed that duck had higher (P<0.05) carcass and organs weight and percentages than GF, also males irrespective of the breed gave higher (P<0.05) carcass and organs weight and percentages than their female counterparts. At interaction level male ducks still gave higher (P<0.05) cut-up parts weight and percentages than female, while female GF elicited higher (P<0.05) primal cuts weight and percentages. It was observed from this study that Duck and GF carcass and organs cut-up parts were heavy enough to supply needed protein like chicken. These birds can therefore, be integrated into commercial poultry production to make animal protein more available to consumers.

description: We study the finite-size scaling of the roughness of signals in systems displaying Gaussian 1/f power spectra. It is found that one of the extreme value distributions (Gumbel distribution) emerges as the scaling function when the boundary conditions are periodic. We provide a realistic example of periodic 1/f noise, and demonstrate by simulations that the Gumbel distribution is a good approximation for the case of nonperiodic boundary conditions as well. Experiments on voltage fluctuations in GaAs films are analyzed and excellent agreement is found with the theory.

description: This study was conducted to determine the effect of giving water contaminated with used engine oil on performance, carcass and meat characteristics of West African Dwarf (WAD) rams. 15 WAD rams about 10 months old were used. They were grouped into 5 balanced for weight. Used engine oil was collected from an Auto mechanic workshop in Ayetoro Yewa Ogun state and mixed to 0, 5, 10, 15 and 20ml with one litre of clean water at 0, 0.5, 1.0, 1.5 and 2.0% designated T0, T1, T2, T3 and T4 respectively. The rams were assigned to these treatment groups in a completely randomized design experiment and were given the contaminated water for 13 weeks. Data collected were subjected to analysis of variance (ANOVA) at p=0.05. The results showed that nutrient intake was higher, while water intake decreased (p<0.05) as the level of used engine oil in water increased, nitrogen intakes and urinary nitrogen decreased (p<0.05) as well as nitrogen retention. Although weight gain increased (p<0.05) feed efficiency decreased (p<0.05). Carcass primal cuts and meat characteristics decreased except cooking yield and water holding capacity as used engine oil increased in the given water. It was therefore, recommended that used engine oil should not be allowed to flow freely into the surrounding water bodies where grazing animals may consume it as this may lead to reduction in their water intake which can affect the health of the animals and increased feed intake can affect profit margin of the farmers.

description: We study the emergency of mutual cooperation in evolutionary prisoner's dilemma games when the players are located on a square lattice. The players can choose one of the three strategies: cooperation (C), defection (D) or "tit for tat" (T), and their total payoffs come from games with the nearest neighbors. During the random sequential updates the players adopt one of their neighboring strategies if the chosen neighbor has higher payoff. We compare the effect of two types of external constraints added to the Darwinian evolutionary processes. In both cases the strategy of a randomly chosen player is replaced with probability P by another strategy. In the first case, the strategy is replaced by a randomly chosen one among the two others, while in the second case the new strategy is always C. Using generalized mean-field approximations and Monte Carlo simulations the strategy concentrations are evaluated in the stationary state for different strength of external constraints characterized by the probability P.

description: We consider the third order differential equation derived from the deformed Seiberg-Witten differential for pure ${\cal N}=2$ SYM with gauge group $SU(3)$ in Nekrasov-Shatashvili limit of $Ω$-background. We show that this is the same differential equation that emerges in the context of Ordinary Differential Equation/Integrable Models (ODI/IM) correspondence for $2d$ $A_2$ Toda CFT with central charge $c=98$. We derive the corresponding $QQ$ and related $TQ$ functional relations and establish the asymptotic behaviour of $Q$ and $T$ functions at small instanton parameter $q \rightarrow 0$. Moreover, numerical integration of the Floquet monodromy matrix of the differential equation leads to evaluation of the $A$-cycles $a_{1,2,3}$ at any point of the moduli space of vacua parametrised by the vector multiplet scalar VEVs $\langle \textbf{tr}\,ϕ^2\rangle$ and $\langle \textbf{tr}\,ϕ^3\rangle$ even for large values of $q$ which are well beyond the reach of instanton calculus. The numerical results at small $q$ are in excellent agreement with instanton calculation. We conjecture a very simple relation between Baxter's $T$-function and $A$-cycle periods $a_{1,2,3}$, which is an extension of Alexei Zamolodchikov's conjecture about Mathieu equation.

description: Pistia stratiotes and Lyngbya wollei are the two most common aquatic weeds that flourish in farm canals within the Everglades Agricultural Area of Florida. Identifying a useful application of these weeds would not only address important environmental concerns, but would also be an incentive for farmers to harvest it. The objective of this study was to determine use of P. stratiotes and L. wollei as soil amendments for stimulation of seed germination and root growth in different plant species. The effects of different rates of dried and grounded P. stratiotes and L. wollei on germination and root length of snap bean, corn, sorghum, common lambsquarters, and rice were evaluated using a controlled petri-dish incubation bioassay study. Overall, both amendments had a negative allelopathic effect on germination of all species. The highest reduction in germination of 80 and 43% by P. stratiotes and L. wollei respectively was observed on corn. Rice was the most tolerant to allelopathic effects that emanated from both amendments. There was a significant positive increase in rice root length in response to P. stratiotes rate over the two-week period. This study shows that P. stratiotes can be used as a potential bio-fertilizer to stimulate early growth of rice.

description: The full quantum mechanical collapse of a small relativistic dust shell is studied analytically, asymptotically and numerically starting from the exact finite dimensional classical reduced Hamiltonian recently derived by Háj{\'ı}ček and Kuchař. The formulation of the quantum mechanics encounters two problems. The first is the multivalued nature of the Hamiltonian and the second is the construction of an appropriate self adjoint momentum operator in the space of the shell motion which is confined to a half line. The first problem is solved by identifying and neglecting orbits of small action in order to obtain a single valued Hamiltonian. The second problem is solved by introducing an appropriate lapse function. The resulting quantum mechanics is then studied by means of analytical and numerical techniques. We find that the region of total collapse has very small probability. We also find that the solution concentrates around the classical Schwarzschild radius. The present work obtains from first principles a quantum mechanics for the shell and provides numerical solutions, whose behavior is explained by a detailed WKB analysis for a wide class of collapsing shells.

description: In this note we construct a solution of six-dimensional $F(4)$ gauged supergravity using $AdS_2\times S^3$ warped over an interval as an ansatz. The solution is completely regular, preserves eight of the sixteen supersymmetries of the $AdS_6$ vacuum and is a holographic realization of a line defect in a dual five-dimensional theory. We calculate the expectation value of the defect and the one-point function of the stress tensor in the presence of the defect using holographic renormalization.

description: Light-front Hamiltonian dynamics is used to relate low-energy constituent quark models to deep inelastic unpolarized structure functions of the nucleon. The approach incorporates the correct Pauli principle prescription consistently and it allows a transparent investigation of the effects due to the spin-dependent SU(6)-breaking terms in the quark model Hamiltonian. Both Goldstone-boson-exchange interaction and hyperfine-potential models are discussed in a unified scheme and a detailed comparison, between the two(apparently) different potential prescriptions, is presented.
