description: There exists a lack of aerosol absorption measurement techniques with low uncertainties and without artefacts. We have developed the two-wavelength Photothermal Aerosol Absorption Monitor (PTAAM-2λ), which measures the aerosol absorption coefficient at 532 and 1064 nm. Here we describe its design, calibration and mode of operation and evaluate its applicability, limits and uncertainties. The 532 nm channel was calibrated with ∼ 1 µmol mol−1 NO2, whereas the 1064 nm channel was calibrated using measured size distribution spectra of nigrosin particles and a Mie calculation. Since the aerosolized nigrosin used for calibration was dry, we determined the imaginary part of the refractive index of nigrosin from the absorbance measurements on solid thin film samples. The obtained refractive index differed considerably from the one determined using aqueous nigrosin solution. PTAAM-2λ has no scattering artefact and features very low uncertainties: 4 % and 6 % for the absorption coefficient at 532 and 1064 nm, respectively, and 9 % for the absorption Ångström exponent. The artefact-free nature of the measurement method allowed us to investigate the artefacts of filter photometers. Both the Aethalometer AE33 and CLAP suffer from cross sensitivity to scattering – this scattering artefact is most pronounced for particles smaller than 70 nm. We observed a strong dependence of the filter multiple scattering parameter on the particle size in the 100–500 nm range. The results from the winter ambient campaign in Ljubljana showed similar multiple scattering parameter values for ambient aerosols and laboratory experiments. The spectral dependence of this parameter resulted in AE33 reporting the absorption Ångström exponent for different soot samples with values biased 0.23–0.35 higher than the PTAAM-2λ measurement. Photothermal interferometry is a promising method for reference aerosol absorption measurements.

description: Study of magnetotransport properties of ScPtBi revealed simultaneously: a negative contribution to the longitudinal magnetoresistance, the planar Hall effect, and distinct angular narrowing of the longitudinal magnetoresistance { three hallmarks of chiral magnetic anomaly (pumping of axial charge between Weyl nodes), a distinct property of topological semimetals. Electronic structure calculations show that structural defects, such as antisites and vacancies, bring substantial density of states at the Fermi level of ScPtBi, indicating that it is a semimetal, not a zero-gap semiconductor, as predicted earlier. This is in accord with electrical resistivity in ScPtBi, showing no characteristics of semiconductor. Moreover, below 0.7K we observed an onset of a superconducting transition, with the resistivity disappearing completely below 0.23 K.

description: We study the effect of a coupling between two motor domains in highly-processive motor protein complexes. A simple stochastic discrete model, in which the two parts of the protein molecule interact through some energy potential, is presented. The exact analytical solutions for the dynamic properties of the combined motor species, such as the velocity and dispersion, are derived in terms of the properties of free individual motor domains and the interaction potential. It is shown that the coupling between the motor domains can create a more efficient motor protein that can move faster than individual particles. The results are applied to analyze the motion of helicase RecBCD molecules.

description: The neutrino physics program at the LHC, which will soon be initiated by the FASER experiment, will provide unique opportunities for precision studies of neutrino interaction vertices at high energies. This will also open up the possibility to search for beyond the standard model (BSM) particles produced in such interactions in the specific high-energy neutrino beam-dump experiment. In this study, we illustrate the prospects for such searches in models with the dipole or $Z^\prime$ portal to GeV-scale heavy neutral leptons. To this end, we employ both the standard signature of new physics that consists of a pair of oppositely-charged tracks appearing in the decay vessel, and the additional types of searches. These include high-energy photons and single scattered electrons. We show that such a variety of experimental signatures could significantly extend the sensitivity reach of the future multi-purpose FASER 2 detector during the High-Luminosity phase of the LHC.

description: It was recently emphasised by Riley (2019); Schittenhelm & Wacker (2020) that that in the presence of plateaus in the likelihood function nested sampling (NS) produces faulty estimates of the evidence and posterior densities. After informally explaining the cause of the problem, we present a modified version of NS that handles plateaus and can be applied retrospectively to NS runs from popular NS software using anesthetic. In the modified NS, live points in a plateau are evicted one by one without replacement, with ordinary NS compression of the prior volume after each eviction but taking into account the dynamic number of live points. The live points are replenished once all points in the plateau are removed. We demonstrate it on a number of examples. Since the modification is simple, we propose that it becomes the canonical version of Skilling's NS algorithm.

Implementing a prototype computer integrated construction environment
Creators: name: Gorlick, Andrew L.
Publisher: name: University of British Columbia
Year: 2009

description: Construction projects rely on a large body of information produced by many sources at many levels of abstraction and detail. This is a major contributing factor to the fragmentation of construction data. One possible solution to this fragmentation is Computer Integrated Construction (CIC). CIC provides methods for handling the information generated throughout the lifecycle of a project. The Construction Management Group at the University of British Columbia has developed a model for computer integration called Total Project Systems (TOPS). TOPS is a conceptual model with the potential to provide the basis for the development of a new class of CIC environments that are comprehensive, integrated, and flexible. Therefore, the main goal of this research was to develop a prototype CIC system based on the TOPS model and then to test the system to determine if the TOPS model provides a suitable basis for the development of the next generation of CIC systems. The main approach was to develop a TOPS Implementation Prototype (TIP). This prototype was a multi-tiered architecture with repository technology at the core providing the persistence management functions. The TIP adopted an open, modular, and non-proprietary architecture so that any application could 'plug-in' to the system via standard TIP interfaces. The TIP also supported an architecture capable of being distributed via the Internet. Repository technology was used to create a robust, integrated data source for the TIP. Repository technology is an innovative database technology developed by the software industry. It further enhanced the TIP architecture by making it extensible and by supporting data evolution and the dynamic development of project schemas (i.e. schema evolution) without destroying information already stored in the database. The TIP was successfully implemented and both a generic data browser application and a specific project management tool (a short cycle scheduling application) were constructed to test the potential of the prototype. The system performed well (given its prototype nature) and provided useful results on the TOPS approach for developing future integrated construction environments.
Electron and photon reconstruction and identification with the CMS experiment at the CERN LHC

description: The performance is presented of the reconstruction and identification algorithms for electrons and photons with the CMS experiment at the LHC. The reported results are based on proton-proton collision data collected at a center-of-mass energy of 13 TeV and recorded in 2016-2018, corresponding to an integrated luminosity of 136 fb$^{-1}$. Results obtained from lead-lead collision data collected at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV are also presented. Innovative techniques are used to reconstruct the electron and photon signals in the detector and to optimize the energy resolution. Events with electrons and photons in the final state are used to measure the energy resolution and energy scale uncertainty in the recorded events. The measured energy resolution for electrons produced in Z boson decays in proton-proton collision data ranges from 2 to 5%, depending on electron pseudorapidity and energy loss through bremsstrahlung in the detector material. The energy scale in the same range of energies is measured with an uncertainty smaller than 0.1 (0.3)% in the barrel (endcap) region in proton-proton collisions and better than 1 (3)% in the barrel (endcap) region in heavy ion collisions. The timing resolution for electrons from Z boson decays with the full 2016-2018 proton-proton collision data set is measured to be 200 ps.

description: This basic qualitative study catalogued the collective insight of Black women student affairs professionals regarding the development and evolution of professional counterspaces in the future. Focus group discussions were facilitated with 50 women participating in a professional counterspace (PC) in the U.S., known as the African American Women’s Summit. Participants were asked to explore the following topics: 1) the purposes of PCs for Black women, 2) how PCs can be enhanced with regard to curriculum content and delivery, and 3) how PCs can be enhanced with regard to opportunities for leadership. Findings indicated that Black women in student affairs still need professional development opportunities that allow them to share their collective wisdom, and that are focused on helping them combat isolation and succeed in the profession. In addition, these types of PCs should include a high degree of interactivity among participants, feature a structured curriculum focused on concrete skill and professional competency development, and provide opportunities for prolonged engagement, perhaps even virtually. Finally, the leadership of PCs for Black women in student affairs can be enhanced by engaging in clear and regular communication with participants, maximizing opportunities for leadership among participants, and using technology to facilitate participants’ leadership development.

description: Although multiple studies acknowledge the significance of mentoring for African American women doctoral students, the literature lacks empirical support for the formation, sustainability and outcomes of mentoring relationships. In academia, African American women are an understudied subject which leads to a paucity of educational programming and policies that address their specific learning needs. Without targeted research, educators are limited in their ability to understand African American women doctoral students’ educational needs. The purpose of this collaborative autoethnography was to examine the reflections of four women participating in a doctoral sister circle called UUSC. This study explored their lived experiences and ways UUSC nurtured, supported, and empowered both the students and their mentor. Data analysis showcased themes of commitment, community and consciousness which can be instructive for other African American women doctoral students and mentors. Findings indicated that in safe spaces, such as this sister circle, where African American women are authentically concerned about each other’s well being and success, their level of commitment and consciousness increases. This work has implications for educators and students because it provides a roadmap for addressing the unique learning needs of African American women through mentoring.

description: We study KKLT type models with moduli-mixing superpotential. In several string models, gauge kinetic functions are written as linear combinations of two or more moduli fields. Their gluino condensation generates moduli-mixing superpotential. We assume one of moduli fields is frozen already around the string scale. It is found that Kähler modulus can be stabilized at a realistic value without tuning 3-form fluxes because of gluino condensation on (non-)magnetized D-brane. Furthermore, we do not need to highly tune parameters in order to realize a weak gauge coupling and a large hierarchy between the gravitino mass and the Planck scale, when there exists non-perturbative effects on D3-brane. SUSY breaking patterns in our models have a rich structure. Also, some of our models have cosmologically important implications, e.g., on the overshooting problem and the destabilization problem due to finite temperature effects as well as the gravitino problem and the moduli problem.

description: We present direct spectroscopic measurements of the broad 2175~Å absorption feature in 505 star-forming main-sequence galaxies at $1.3\le z\le 1.8$ using individual and stacked spectra from the zCOSMOS-deep survey. Significant 2175~Å excess absorption features of moderate strength are measured, especially in the composite spectra. The excess absorption is well described by a Drude profile. The bump amplitude expressed in units of $k(λ)=A(λ)/E(B-V)$, relative to the featureless Calzetti et al. law, has a range $B_k\approx0.2\textrm{--}0.8$. The bump amplitude decreases with the specific star formation rate (sSFR), while it increases moderately with the stellar mass. However, a comparison with local "starburst" galaxies shows that the high-redshift main-sequence galaxies have stronger bump features, despite having a higher sSFR than the local sample. Plotting the bump strength against the $Δ\log\mathrm{sSFR}\equiv \log \left( \mathrm{SFR}/\mathrm{SFR_{MS}}\right)$ relative to the main sequence, however, brings the two samples into much better concordance. This may indicate that it is the recent star formation history of the galaxies that determines the bump strength through the destruction of small carbonaceous grains by supernovae and intense radiation fields coupled with the time delay of $\sim1~\mathrm{Gyr}$ in the appearance of carbon-rich asymptotic giant branch stars.

description: The issue of partitioning a network into communities has attracted a great deal of attention recently. Most authors seem to equate this issue with the one of finding the maximum value of the modularity, as defined by Newman. Since the problem formulated this way is NP-hard, most effort has gone into the construction of search algorithms, and less to the question of other measures of community structures, similarities between various partitionings and the validation with respect to external information. Here we concentrate on a class of computer generated networks and on three well-studied real networks which constitute a bench-mark for network studies; the karate club, the US college football teams and a gene network of yeast. We utilize some standard ways of clustering data (originally not designed for finding community structures in networks) and show that these classical methods sometimes outperform the newer ones. We discuss various measures of the strength of the modular structure, and show by examples features and drawbacks. Further, we compare different partitions by applying some graph-theoretic concepts of distance, which indicate that one of the quality measures of the degree of modularity corresponds quite well with the distance from the true partition. Finally, we introduce a way to validate the partitionings with respect to external data when the nodes are classified but the network structure is unknown. This is here possible since we know everything of the computer generated networks, as well as the historical answer to how the karate club and the football teams are partitioned in reality. The partitioning of the gene network is validated by use of the Gene Ontology database, where we show that a community in general corresponds to a biological process.

description: The changing tide of faculty has brought with it increasing numbers of faculty members serving in non-tenure-track roles. Scholars have argued this increase in contingent faculty includes an increase in inequities and has created a stratified class system between tenure-track faculty (TTF) and non-tenure-track faculty (NTTF). The majority of NTTF numbers comprise women of Color, across race and ethnicity, serving in both full-time and adjunct capacities. The cultural, historical, and sociopolitical occupation of women of Color in higher education has been rife with inequity, marginalization, and oppression. In addition to their duties across rank and appointment, women of Color faculty are more likely to take up the labor of care. Labor concerns have been raised in the both the literature of contingent faculty and women of Color faculty. Yet, few scholars have systematically studied the experiences or overlapping systems of oppression women of Color who are NTTF faculty face in the academy. Fewer still have examined the specific experiences of Black women faculty serving in contingent roles. For our study, we used a conceptual framework comprising Black feminist thought, care work, and labor justice to analyze scholarly personal narratives and focus group interviews of four Black women serving in full-time NTTF roles. Our study aims to provide a window into the intersected realities Black women contingent faculty members within the academy and a pathway forward for academic leadership.

description: We introduce novel relations between the derivatives [$\partial^{n}ρ(λ, m_{l})/\partial m_{l}^n$] of the Dirac eigenvalue spectrum [$ρ(λ, m_{l})$] with respect to the light sea quark mass ($m_{l}$) and the $(n+1)$-point correlations among the eigenvalues ($λ$) of the massless Dirac operator. Using these relations we present lattice QCD results for $\partial^{n}ρ(λ, m_{l})/\partial m_{l}^n$ ($n=1, 2, 3$) for $m_{l}$ corresponding to pion masses $m_π=160-55$ MeV, and at a temperature of about 1.6 times the chiral phase transition temperature. Calculations were carried out using (2+1) flavors of highly improved staggered quarks with the physical value of strange quark mass, three lattice spacings $a=0.12, 0.08, 0.06$ fm, and lattices having aspect ratios $4-9$. We find that $ρ(λ\to0, m_{l})$ develops a peaked structure. This peaked structure arises due to non-Poisson correlations within the infrared part of the Dirac eigenvalue spectrum, becomes sharper as $a\to0$, and its amplitude is proportional to $m_{l}^2$. We demonstrate that this $ρ(λ\to0,m_l)$ is responsible for the manifestations of axial anomaly in two-point correlation functions of light scalar and pseudoscalar mesons. After continuum and chiral extrapolations we find that axial anomaly remains manifested in two-point correlation functions of scalar and pseudoscalar mesons in the chiral limit.

description: The nature of ultrahigh-energy cosmic rays (UHECRs) at energies >10^20 eV remains a mystery. They are likely to be of extragalactic origin, but should be absorbed within ~50 Mpc through interactions with the cosmic microwave background. As there are no sufficient powerful accelerators within this distance from the Galaxy, explanations for UHECRs range from unusual astrophysical sources to exotic string physics. Also unclear is whether UHECRs consist of protons, heavy nuclei, neutrinos or gamma-rays. To resolve these questions, larger detectors with higher duty cycles and which combine multiple detection techniques are needed. Radio emission from UHECRs, on the other hand, is unaffected by attenuation, has a high duty cycle, gives calorimetric measurements and provides high directional accuracy. Here we report the detection of radio flashes from cosmic-ray air showers using low-cost digital radio receivers. We show that the radiation can be understood in terms of the geosynchrotron effect. Our results show that it should be possible to determine the nature and composition of UHECRs with combined radio and particle detectors, and to detect the ultrahigh-energy neutrinos expected from flavour mixing.

description: Quantum state transfer (QST) provides a method to send arbitrary quantum states from one system to another. Such a concept is crucial for transmitting quantum information into the quantum memory, quantum processor, and quantum network. The standard benchmark of QST is the average fidelity between the prepared and received states. In this work, we provide a new benchmark which reveals the non-classicality of QST based on spatio-temporal steering (STS). More specifically, we show that the local-hidden-state (LHS) model in STS can be viewed as the classical strategy of state transfer. Therefore, we can quantify the non-classicality of QST process by measuring the spatio-temporal steerability. We then apply the spatio-temporal steerability measurement technique to benchmark quantum devices including the IBM quantum experience and QuTech quantum inspire under QST tasks. The experimental results show that the spatio-temporal steerability decreases as the circuit depth increases, and the reduction agrees with the noise model, which refers to the accumulation of errors during the QST process. Moreover, we provide a quantity to estimate the signaling effect which could result from gate errors or intrinsic non-Markovian effect of the devices.

description: The Healthcare Internet-of-Things (H-IoT), commonly known as Digital Healthcare, is a data?driven infrastructure that highly relies on smart sensing devices (i.e., blood pressure monitors, temperature sensors, etc.) for faster response time, treatments, and diagnosis. However, with the evolving cyber threat landscape, IoT devices have become more vulnerable to the broader risk surface (e.g., risks associated with generative AI, 5G-IoT, etc.), which, if exploited, may lead to data breaches, unauthorized access, and lack of command and control and potential harm. This paper reviews the fundamentals of healthcare IoT, its privacy, and data security challenges associated with machine learning and H-IoT devices. The paper further emphasizes the importance of monitoring healthcare IoT layers such as perception, network, cloud, and application. Detecting and responding to anomalies involves various cyber-attacks and protocols such as Wi-Fi 6, Narrowband Internet of Things (NB-IoT), Bluetooth, ZigBee, LoRa, and 5G New Radio (5G NR). A robust authentication mechanism based on machine learning and deep learning techniques is required to protect and mitigate H-IoT devices from increasing cybersecurity vulnerabilities. Hence, in this review paper, security and privacy challenges and risk mitigation strategies for building resilience in H-IoT are explored and reported.

description: We study the self-adjoint extensions of the Hamiltonian operator with symmetric potentials which go to $-\infty$ faster than $-|x|^{2p}$ with $p>1$ as $x\to\pm\infty$. In this extension procedure, one requires the Wronskian between any states in the spectrum to approach to the same limit as $x\to\pm\infty$. Then the boundary terms cancel and the Hamiltonian operator can be shown to be hermitian. Discrete bound states with even and odd parities are obtained. Since the Wronskian is not required to vanish asymptotically, the energy eigenstates could be degenerate. Some explicit examples are given and analyzed.

description: We study a model of correlated electrons coupled by tunnelling to a layer of itinerant metallic electrons, which allows to interpolate from a frustrated limit favorable to spin liquid states to a Kondo-lattice limit favorable to interlayer coherent heavy metallic states. We study the competition of the spinon fermi surface state and the interlayer coherent heavy Kondo metal that appears with increasing tunnelling. Employing a slave rotor mean-field approach, we obtain a phase diagram and describe two regimes where the spin liquid state is destroyed by weak interlayer tunnelling, (i) the Kondo limit in which the correlated electrons can be viewed as localized spin moments and (ii) near the Mott metal-insulator-transition where the spinon Fermi surface transitions continuously into a Fermi liquid. We study the shape of LDOS spectra of the putative spin liquid layer in the heavy Fermi liquid phase and describe the temperature dependence of its width arising from quasiparticle interactions and disorder effects throughout this phase diagram, in an effort to understand recent STM experiments of the candidate spin liquid 1T-TaSe$_2$ residing on metallic 1H-TaSe$_2$. Comparison of the shape and temperature dependence of the theoretical and experimental LDOS suggest that this system is either close to the localized Kondo limit, or in an intermediate coupling regime where the Kondo coupling and the Heisenberg exchange interaction are comparable.

description: The application of a matrix-based reconstruction protocol for obtaining Molecular Frame (MF) photoelectron angular distributions (MFPADs) from laboratory frame (LF) measurements (LFPADs) is explored. Similarly to other recent works on the topic of MF reconstruction, this protocol makes use of time-resolved LF measurements, in which a rotational wavepacket is prepared and probed via photoionization, followed by a numerical reconstruction routine; however, in contrast to other methodologies, the protocol developed herein does not require determination of photoionization matrix elements, and consequently takes a relatively simple numerical form (matrix transform making use of the Moore-Penrose inverse). Significantly, the simplicity allows application of the method to the successful reconstruction of MFPADs for polyatomic molecules. The scheme is demonstrated numerically for two realistic cases, $N_2$ and $C_2H_4$. The new technique is expected to be generally applicable for a range of MF reconstruction problems involving photoionization of polyatomic molecules.

description: A large proportion of the on-going reductions in global food prices are attributable to the efficiency gains associated with various green revolutions. Unfortunately the welfare gains associated with such productivity growth are unevenly distributed, with many African states reaping relatively few benefits. One possible reason for this is the failure of African agriculture to retain its relative competitiveness in global agricultural and food markets, and hence, the welfare gains associated with reductions in consumer prices are largely offset by the welfare losses associated with reductions in producer prices. The analyses reported in this paper explore how changes in domestic and international agricultural efficiency will impact upon the welfare of households and the profitability of agricultural and food industries in South Africa. The results are generated from a computable general equilibrium (CGE) model for South Africa with highly disaggregated food and agricultural sectors. The scenarios reported focus on three dimensions of domestic technology change; changes in the efficiencies with which intermediate inputs, primary inputs and land are used, and one international dimension; changes in the world prices of agricultural and food products. The results indicate that both domestic and international efficiency gains have positive net welfare effects for South Africa. In the case of domestic efficiency gains the net benefit is marginally greater, mainly because of the smaller negative welfare consequences for domestic producers. This can be explained by domestic producers increased penetration of export markets, which offsets the negative welfare effects associated with a reduction in producer prices. The paper concludes with an assessment of the differential impacts upon the agronomic regions of South Africa and the different household types. These results suggest that while the distribution of the consumer benefits is biased towards poorer households, the distribution of the producer benefits is biased towards relatively richer agricultural areas.
Multi-seeded multi-mode formation of embedded clusters in the RMC: Structured star formation toward the south-east boundary

description: The Rosette Molecular Complex contains embedded clusters with diverse properties and origins. We have previously explored the shell mode of formation in the north (Regions A & B) and the massive concentrations in the ridge (Region C). Here, we explore star formation towards the south of the complex, Region D, based on data from the spatially complete 2 Micron All Sky Survey. We find that stars are forming prolifically throughout this region in a highly structured mode with both clusters and loose aggregates detected. The most prominent cluster (Region D1) lies in the north-center. This cluster is over 20 pc to the south of the Monoceros ridge, the interface of the emerging young OB cluster NGC 2244 with its ambient molecular clouds. In addition, there are several branches stemming from AFGL 961 in Region C and extending to the south-east boundary of the cloud. We invoke a tree model to interpret this pattern, corresponding to probable tracks of abrupt turbulent excitation and subsequent decay. Alternatively, we discuss gravoturbulent collapse scenarios based on numerical simulations. Relative stellar ages and gas flow directions will differentiate between these mechanisms.

Socioeconomic Analysis of the Roles of Agriculture in Morocco

description: The study conducted in morocco, within FAO/ROA project, showed that agriculture, while being affected by exogenous natural conditions and macroeconomic factors, contributes significantly to environmental amenities, poverty alleviation, social viability and national culture. The analysis of environmental roles showed an asymmetry of information in favor of negative externalities. However, agriculture provides positive externalities as demonstrated through the economic evaluation of three cases concerning landscape beautification, agro tourism and animal biodiversity conservation. Poverty has been exacerbated in depth, volume and severity and remains a rural phenomenon with a visible concentration in areas characterized by limited land endowments, low productivity activities and weak levels of economic development. Tough referred to as a national sovereignty attribute, food security has clearly deteriorated, during the 1994-2000 period, as evidenced by staple food availability, access and stability. Despite this evolution, agriculture still contributes to social viability in terms of spatial distribution of the population, the regulation of migratory flows as well as in terms of the preservation of community solidarity and the formation of social capital. Focus group interviews showed, in particular, that agriculture and rurality are closely related and that both have been subject to transformations which have affected people perceptions of agriculture contributions to society. The analysis, also, revealed the existence of linkages among externalities associated with the different roles of agriculture. Existing synergies or conflicts are crucial to the level of agriculture performance. This complex implies adoption of a holistic approach in designing integrate policy alternative. The latter should combine agricultural and non-agricultural sector policies and macroeconomic policies. Therefore, implementation of new options, in the absence of adequate and functional institutions, requires government intervention in order to prevent increasing uncontrolled market liberalization that may be detrimental to the stability the whole national country.

description: It is investigated the cosmological dynamics of scalar-torsion $f(T,ϕ)$ gravity as a dark energy model, where $T$ is the torsion scalar of teleparallel gravity and $ϕ$ is a canonical scalar field. In this context, we are concerned with the phenomenology of the class of models with non-linear coupling to gravity and exponential potential. We obtain the critical points of the autonomous system, along with the stability conditions of each one of them and their cosmological properties. Particularly, we show the existence of new attractors with accelerated expansion, as well as, new scaling solutions in which the energy density of dark energy scales as the background fluid density, thus, defining the so-called scaling radiation and scaling matter epochs. The scaling solutions are saddle points, and therefore, the system exits these solutions to the current epoch of cosmic acceleration, towards an attractor point describing the dark energy-dominated era.

description: We investigate a possible explanation for the NuTeV anomaly in terms of a nuclear correction difference between u_v and d_v distributions. Analyzing deep elastic scattering and Drell-Yan data for nuclear targets, we try to determine the correction difference and its effect on the anomaly. We find that the difference cannot be precisely determined at this stage due to the lack of data which are sensitive to the difference. Therefore, it is difficult to draw a solid conclusion about its effect although the anomaly could be explained, at least partially, by this kind of nuclear correction.
