description: Big Data is used by data miner for analysis purpose which may contain sensitive information. During the procedures it raises certain privacy challenges for researchers. The existing privacy preserving methods use different algorithms that results into limitation of data reconstruction while securing the sensitive data. This paper presents a clustering based privacy preservation probabilistic model of big data to secure sensitive information..model to attain minimum perturbation and maximum privacy. In our model, sensitive information is secured after identifying the sensitive data from data clusters to modify or generalize it.The resulting dataset is analysed to calculate the accuracy level of our model in terms of hidden data, lossed data as result of reconstruction. Extensive experiements are carried out in order to demonstrate the results of our proposed model. Clustering based Privacy preservation of individual data in big data with minimum perturbation and successful reconstruction highlights the significance of our model in addition to the use of standard performance evaluation measures.

description: Large galaxies grow through the accumulation of dwarf galaxies. In principle it is possible to trace this growth history using the properties of a galaxy's stellar halo. Previous investigations of the galaxy M31 (Andromeda) have shown that outside a radius of 25 kpc the population of halo globular clusters is rotating in alignment with the stellar disk, as are more centrally located clusters. The M31 halo also contains coherent stellar substructures, along with a smoothly distributed stellar component. Many of the globular clusters outside 25 kpc are associated with the most prominent substructures, while others are part of the smooth halo. Here we report a new analysis of the kinematics of these globular clusters. We find that the two distinct populations are rotating with perpendicular orientations. The rotation axis for the population associated with the smooth halo is aligned with the rotation axis for the plane of dwarf galaxies that encircles M31. We interpret these separate cluster populations as arising from two major accretion epochs, likely separated by billions of years. Stellar substructures from the first epoch are gone, but those from the more recent second epoch still remain.

description: With eight-year-old pear-jujube trees with uniform and good growth as the research object, different concentrations of iron and zinc fertilizers were sprayed to the leaves, and the changes in the contents of vitamin C, total flavonoids, enzyme, as well as the removal rates of hydroxyl radicals, 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH) and hydrogen peroxide by polyphenols in pear-jujube were studied, so as to explore the effects of iron and zinc fertilizers on antioxidant activity of pear-jujube in loess hilly region. The results showed that different treatments affected the content of vitamin C and significantly increased the content of total flavonoids in pear-jujube. In the treatment of 0.6% FeSO4+0.3% ZnSO4 (L3), the contents of vitamin C and total flavonoids were both highest, 2.86 mg/g and 3.02 mg/g, 21.8% and 105.4% higher than CK (P<0.05). Different fertilization treatments effectively reduced the activities of ascorbate oxidase and polyphenol oxidase in pear-jujube. The activity of ascorbate oxidase was lowest in the treatment of 0.6% FeSO4+0.3% ZnSO4 (oxidized ascorbic acid 0.069 mg/(g·min) FW), 75.1% lower than CK); and the activity of polyphenol oxidase was lowest in the L3 treatment (oxidized ascorbic acid 0.146 mg/(g·min) FW, 42.0% lower than CK). Polyphenols of pear-jujube could effectively remove hydroxyl radicals, DPPH· and hydrogen peroxide. This was more significant in L3 treatment, of which the antioxidant activity was the best.

description: The effects of calcium application rate on dry matter accumulation and yield of peanut were studied under high-yielding field condition. The variety used for the study was Tang A8252 (Spanish peanut). The results showed that number of full fruit, dry weight per plant, kernel yield, and pod yield all increased with calcium application increased, and they decreased when calcium application rate was more than 150 kg/ha. Both the height of main stem and the length of side shoot decreased with calcium application increased. Therefore, to obtain the optimal agronomic character index and the highest yield benefit, the suggested calcium application rate would be 150 kg/ha for peanut.

description: Hexagonal polyominoes are polyominoes on the honeycomb lattice. We enumerate the symmetry classes of convex hexagonal polyominoes. Here convexity is to be understood as convexity along the three main column directions. We deduce the generating series of free (i.e. up to reflection and rotation) and of asymmetric convex hexagonal polyominoes, according to area and half-perimeter. We give explicit formulas or implicit functional equations for the generating series, which are convenient for computer algebra.

description: The government of Lao PDR and local civil society groups are implementing several agricultural initiatives and recognize the importance that home gardens (HG) contribute to household (HH) food security. Despite its importance, studies on HG rural farming vulnerable HHs are limited. Thus, this study assesses the HG characteristics and how it contributes to food security among three types of rural upland vulnerable farmer HHs of 16 villages in Phoukoud District, Lao PDR: People with Disability Households (PWDHH), Female-Headed Households (FHHH), and Other Vulnerable Households (OVHH). It has two specific objectives, first, to assess HG characteristics and second, to evaluate HG relationships to HH food security amongst the 3 types of upland vulnerable HHs. The research used mixed methods of qualitative and quantitative data collection and analysis. The study found home gardens near and far from homes, with sizes varying from smaller to larger plots with FHHHs HG being the largest, furthest from home, and more time was spent, whereas PWDHH's HG were the closest, smallest, less time was spent, but they harvested the most compared to other HHs. Women felt empowered as managers and owners of their HG, whereas men mainly thought it was women’s job and only helped with tasks such as fencing, clearing and digging the land. The majority of households used HG crops for HH consumption, with fewer HHs selling surplus crops. The study also found various levels of food insecurity but as the number of HG increased, crop production improved, and food insecurity decreased. The study also revealed significant disparities among the three types of vulnerable HHs, with FHHHs experiencing the most severe food insecurity, and showed the least progress in addressing food insecurity over time. Households primarily used traditional methods to select and store seeds, study found loss of seed amongst HHs due to poor seed storage practices. The study found 83 different types of HG crops, with FHHHs producing the least diverse crop. The study findings support HG as a reliable, year-round food source which has the potential to alleviate food insecurity by increasing food availability, access, utilisation and stability. This study discusses the constraints and opportunities and highlights the positive impact of HG in reducing food insecurity but acknowledges that HG alone cannot eliminate all food security issues. The study offers recommendations for targeted interventions and policies to improve HG practices, address current challenges of food security in rural upland areas of Laos, and contributes to attaining global Sustainable Development Goals (SDGs) #2, #3, #12, and #13.

description: We consider an active run-and-tumble particle (RTP) in $d$ dimensions and compute exactly the probability $S(t)$ that the $x$-component of the position of the RTP does not change sign up to time $t$. When the tumblings occur at a constant rate, we show that $S(t)$ is independent of $d$ for any finite time $t$ (and not just for large $t$), as a consequence of the celebrated Sparre Andersen theorem for discrete-time random walks in one dimension. Moreover, we show that this universal result holds for a much wider class of RTP models in which the speed $v$ of the particle after each tumbling is random, drawn from an arbitrary probability distribution. We further demonstrate, as a consequence, the universality of the record statistics in the RTP problem.

description: We present spectroscopic and photometric observations of the afterglow of GRB 021211 and the discovery of its associated supernova, SN 2002lt. The spectrum shows a broad feature (FWHM = 150 A), around 3770 A (in the rest-frame of the GRB), which we interpret as Ca H+K blueshifted by 14400 km/s. Potential sources of contamination due to the host galaxy and/or residuals of telluric absorption have been analyzed and ruled out. Overall, the spectrum shows a suggestive resemblance with the one of the prototypical type-Ic SN 1994I. This might indicate that GRBs are produced also by standard type-Ic supernovae.

description: Let $Γ$ be a split extension of a finite-dimensional algebra $Λ$ by a nilpotent bimodule $_ΛE_Λ$, and let $(T,P)$ be a pair in $\modΛ$ with $P$ projective. We prove that $(T\otimes_ΛΓ_Γ, P\otimes_ΛΓ_Γ)$ is a support $τ$-tilting pair in $\mod Γ$ if and only if $(T,P)$ is a support $τ$-tilting pair in $\mod Λ$ and $\Hom_Λ(T\otimes_ΛE,τT_Λ)=0=\Hom_Λ(P,T\otimes_ΛE)$. As applications, we obtain a necessary and sufficient condition such that $(T\otimes_ΛΓ_Γ, P\otimes_ΛΓ_Γ)$ is support $τ$-tilting pair for a cluster-tilted algebra $Γ$ corresponding to a tilted algebra $Λ$; and we also get that if $T_1,T_2\in\modΛ$ such that $T_1\otimes_ΛΓ$ and $T_2\otimes_ΛΓ$ are support $τ$-tilting $Γ$-modules, then $T_1\otimes_ΛΓ$ is a left mutation of $T_2\otimes_ΛΓ$ if and only if $T_1$ is a left mutation of $T_2$.
Direct SUSY dark matter detection-Theoretical rates due to the spin

Year: 2004
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The recent WMAP data have confirmed that exotic dark matter together with the vacuum energy (cosmological constant) dominate in the flat Universe. Thus the direct dark matter detection, consisting of detecting the recoiling nucleus, is central to particle physics and cosmology. Supersymmetry provides a natural dark matter candidate, the lightest supersymmetric particle (LSP). The relevant cross sections arise out of two mechanisms: i) The coherent mode, due to the scalar interaction and ii) The spin contribution arising from the axial current. In this paper we will focus on the spin contribution, which is expected to dominate for light targets. For both modes it is possible to obtain detectable rates, but in most models the expected rates are much lower than the present experimental goals. So one should exploit two characteristic signatures of the reaction, namely the modulation effect and, in directional experiments, the correlation of the event rates with the sun's motion. In standard non directional experiments the modulation is small, less than two per cent. In the case of the directional event rates we like to suggest that the experiments exploit two features, of the process, which are essentially independent of the SUSY model employed, namely: 1) The forward-backward asymmetry, with respect to the sun's direction of motion, is very large and 2) The modulation is much larger, especially if the observation is made in a plane perpendicular to the sun's velocity. In this case the difference between maximum and minimum can be larger than 40 per cent and the phase of the Earth at the maximum is direction dependent.

description: Striking differences exist between urban and rural trends in revenues, expenditures, and debts of local governments for 1977-82. The biggest difference was the way urban and rural areas reacted to cuts in aid. As real Federal aid declined, big city governments cut real spending and reduced their local revenue raising efforts. Most rural governments increased real spending by increasing their local revenue efforts, resulting in higher fiscal burdens on rural residents.

Interestingly, we find that the quantization of the Hall conductivity is severely dependent on the value of the chemical potential and the magnetic field. The origin of this unusual quantization, attributed to the Landau level spectrum of AAA-stacked TLG, is explained in detail. We show that is a characteristic of the multilayer graphene structures with AA stacking order.

description: Developing biomimetic 3D constructs to study neuronal networks and screen therapeutic agents in vitro is critical to address the limitations of conventional 2D cultures used in pre-clinical studies. Since substrate stiffness and culture dimensionality influence behaviour of neurons in vitro, using rigid 2D substrates limits translational potential and physiological accuracy. To improve physiological relevance of in vitro neuronal cultures, 3D constructs are engineered to recapitulate the material properties of the cerebral matrix which neuronal networks depend upon in vivo. Of particular importance is mimicking the low Young’s modulus of the extracellular matrix in the brain, while providing regions for neuronal adhesion to promote viability and growth. To this end, a 3D microsphere-based strategy was investigated, where multiple microspheres collectively acting as a scaffold with high interconnected porosity were used to provide adhesive, 3D growth area. Specifically, agarose—a natural polysaccharide—was used to fabricate soft microspheres which are subsequently functionalized with the bio-inspired and adhesive polymer, polydopamine. Microfluidic technology yielded an agarose microsphere population of highly monodisperse diameters. Successful functionalization of the microspheres with polydopamine was verified through identification of the characteristic Raman spectra of polydopamine. Measured through atomic force nanoindentations in water, the Young’s modulus of the agarose microsphere measured 4.9 ± 0.6 kPa –10⁶ times lower than conventional culture-ware. The Young’s modulus was found to increase to 26.8 ± 17.9 kPa after functionalization with polydopamine, where the large standard deviation was attributed to the nano- mechanical and -topographical non- homogeneity of the resulting surface due to polydopamine aggregation Microsphere stiffness followed the same trend while also increasing as a function of indentation depth. Functionalization of microspheres with polydopamine was also shown to significantly increase material surface adhesion compared to poly-D-lysine and laminin functionalized glass microspheres (a recently reported microsphere-based model). Finally, the microspheres were shown to provide embryonic cerebral neurons with 3D growth area while facilitating neural adhesion and neurite development. This work provides a 3D, soft and adhesive in vitro model for neuronal culture with improved biomimetics over current microsphere-based protocols, and ultimately rigid 2D culture-ware.

description: In the literature different concepts of compatibility between a projective structure and a conformal structure on a differentiable manifold are used. In particular compatibility in the sense of Weyl geometry is slightly more general than compatibility in the Riemannian sense. An often cited paper [Ehlers-Pirani-Schild:1972] introduces still another criterion which is natural from the physical point of view: every light like geodesics of of the conformal structure is a geodesics of the projective structure. Their claim that this type of compatibility is sufficient for introducing a Weylian metric has recently been questioned in [Trautman:2012] and [Scholz:2019]. Here it is proved that the conjecture of EPS is correct.

description: BACKGROUND AND AIMS: Coronary artery calcium (CAC) is validated for risk prediction among middle-aged adults, but there is limited research exploring implications of CAC among older adults. We used data from the Atherosclerosis Risk in Communities (ARIC) study to evaluate the association of CAC with domains of healthy and unhealthy aging in adults aged ≥75 years. METHODS: We included 2,290 participants aged ≥75 years free of known coronary heart disease who underwent CAC scoring at study visit 7. We examined the cross-sectional association of CAC = 0, 1-999 (reference), and ≥1000 with seven domains of aging: cognitive function, hearing, ankle-brachial index (ABI), pulse-wave velocity (PWV), forced vital capacity (FVC), physical functioning, and grip strength. RESULTS: The mean age was 80.5 ± 4.3 years, 38.6% male, and 77.7% White. 10.3% had CAC = 0 and 19.2% had CAC≥1000. Individuals with CAC = 0 had the lowest while those with CAC≥1000 had the highest proportion with dementia (2% vs 8%), hearing impairment (46% vs 67%), low ABI (3% vs 18%), high PWV (27% vs 41%), reduced FVC (34% vs 42%), impaired grip strength (66% vs 74%), and mean composite abnormal aging score (2.6 vs 3.7). Participants with CAC = 0 were less likely to have abnormal ABI (aOR:0.15, 95%CI:0.07-0.34), high PWV (aOR:0.57, 95%CI:0.41-0.80), and reduced FVC (aOR:0.69, 95%CI:0.50-0.96). Conversely, participants with CAC≥1000 were more likely to have low ABI (aOR:1.74, 95%CI:1.27-2.39), high PWV (aOR:1.52, 95%CI:1.15-2.00), impaired physical functioning (aOR:1.35, 95%CI:1.05-1.73), and impaired grip strength (aOR:1.46, 95%CI:1.08-1.99). CONCLUSIONS: Our findings highlight CAC as a simple measure broadly associated with biological aging, with clinical and research implications for estimating the physical and physiological aging trajectory of older individuals.

description:
Group concept mapping (GCM) has been successfully employed in program planning and evaluation for over 25 years. The broader set of systems thinking methodologies (of which GCM is one), have only recently found their way into the field. We present an overview of systems thinking emerging from a system dynamics (SD) perspective, and illustrate the potential synergy between GCM and SD. As with GCM, participatory processes are frequently employed when building SD models; however, it can be challenging to engage a large and diverse group of stakeholders in the iterative cycles of divergent thinking and consensus building required, while maintaining a broad perspective on the issue being studied. GCM provides a compelling resource for overcoming this challenge, by richly engaging a diverse set of stakeholders in broad exploration, structuring, and prioritization. SD provides an opportunity to extend GCM findings by embedding constructs in a testable hypothesis (SD model) describing how system structure and changes in constructs affect outcomes over time. SD can be used to simulate the hypothesized dynamics inherent in GCM concept maps. We illustrate the potential of the marriage of these methodologies in a case study of BECOMING, a federally-funded program aimed at strengthening the cross-sector system of care for youth with severe emotional disturbances.

description: We present the results of the spectral analysis of a sample of short bright $γ$--ray bursts (GRB) detected by BATSE and compare them with the average and time resolved spectral properties of long bright bursts. While the spectral parameters of short GRBs confirm, as expected from previous works based on the hardness ratio, that they are harder than long events, we find that this difference is mainly due to a harder low energy spectral component present in short bursts, rather than to a (marginally) different peak energy. Intriguingly our analysis also reveals that the emission properties of short GRBs are similar to the first 2 s of long events. This might suggest that the central engine of long and short GRBs is the same, just working for a longer time for long GRBs. We find that short bursts do not obey the correlation between peak frequency and isotropic emitted energy for any assumed redshift, while they can obey the similar correlation between the peak frequency and isotropic emitted luminosity. This is consistent with (although not a proof of) the idea that short GRBs emit a $γ$--ray luminosity similar to long GRBs. If they indeed obey the peak frequency -- isotropic luminosity relation, we can estimate the redshift distribution of short bursts, which turns out to be consistent with that of long bursts just with a slightly smaller average redshift.

The purpose of the article is to describe the progress of the Clinical and Translational Science Award (CTSA) Program to address the evaluation-related recommendations made by the 2013 Institute of Medicine's review of the CTSA Program and guidelines published in CTS Journal the same year (Trochim et al., Clinical and Translational Science 2013; 6(4): 303-309). We utilize data from a 2018 national survey of evaluators administered to all 64 CTSA hubs and a content analysis of the role of evaluation in the CTSA Program Funding Opportunity Announcements to document progress. We present four new opportunities for further strengthening CTSA evaluation efforts: (1) continue to build the collaborative evaluation infrastructure at local and national levels; (2) make better use of existing data; (3) strengthen and augment the common metrics initiative; and (4) pursue internal and external opportunities to evaluate the CTSA program at the national level. This article will be of significant interest to the funders of the CTSA Program and the multiple stakeholders in the larger consortium and will promote dialog from the broad range of CTSA stakeholders about further strengthening the CTSA Program's evaluation.

description: With the purpose of assessing classic spectroscopic methods on high-resolution and high signal-to-noise ratio spectra in the near-infrared wavelength region, we selected a sample of 65 F-, G-, and K-type stars observed with CARMENES, the new, ultra-stable, double-channel spectrograph at the 3.5 m Calar Alto telescope. We computed their stellar atmospheric parameters ($T_{\rm eff}$, $\log{g}$, $ξ$, and [Fe/H]) by means of the StePar code, a Python implementation of the equivalent width method that employs the 2017 version of the MOOG code and a grid of MARCS model atmospheres. We compiled four Fe I and Fe II line lists suited to metal-rich dwarfs, metal-poor dwarfs, metal-rich giants, and metal-poor giants that cover the wavelength range from 5300 to 17100 angstroms, thus substantially increasing the number of identified Fe I and Fe II lines up to 653 and 23, respectively. We examined the impact of the near-infrared Fe I and Fe II lines upon our parameter determinations after an exhaustive literature search, placing special emphasis on the 14 $Gaia$ benchmark stars contained in our sample. Even though our parameter determinations remain in good agreement with the literature values, the increase in the number of Fe I and Fe II lines when the near-infrared region is taken into account reveals a deeper $T_{\rm eff}$ scale that might stem from a higher sensitivity of the near-infrared lines to $T_{\rm eff}$.
The Experiences of Nurses Engaging in Therapeutic Relationships with Mothers of Newborns Diagnosed with Neonatal Abstinence Syndrome

description: The therapeutic nurse-client relationship is at the core of nursing practice and is meant to benefit the health and wellbeing of clients (CNA, 2017; CNO, 2006; RNAO 2002). Mothers of newborns diagnosed with neonatal abstinence syndrome (NAS), however, have reported negative relationships with their newborns’ nurses (Cleveland & Gill, 2013; Cleveland & Bonugli, 2014). Likewise, neonatal nurses have also discussed their challenges working with this population of mothers (Demirci et al., 2015; Murphy-Oikonen et al., 2010; Raeside, 2003; Romisher et al., 2018). The purpose of this study was to explore neonatal nurses’ experiences of engaging in therapeutic relationships with mothers of newborns diagnosed with NAS. This qualitative study follows the methods of interpretive description (Thorne, 2016). Eligible participants were recruited using purposeful and convenience sampling. Data was collected by semi-structured telephone interviews. Interviews were audio-recorded and transcribed verbatim, and a thematic analysis was conducted following Thorne’s (2016) alternative sorting technique. Two major themes were identified by researchers. The first theme, building the relationship, is broken down into subthemes assessing the mother and choosing an approach, caring for and involving the mother, making a connection, and getting to know mom and her needs. The second theme, the competing pressures of working with NAS, is further categorized into the subthemes working with baby and mother, collaborating with the Children’s Aid Society, and struggling with stigma. The findings from this study have implications for nursing practice, education, policy, and research that promotes the success of establishing therapeutic relationships with mothers of newborns diagnosed with NAS.

INTRODUCTION: Although the science of team science is no longer a new field, the measurement of team science and its standardization remain in relatively early stages of development. To describe the current state of team science assessment, we conducted an integrative review of measures of research collaboration quality and outcomes. METHODS: Collaboration measures were identified using both a literature review based on specific keywords and an environmental scan. Raters abstracted details about the measures using a standard tool. Measures related to collaborations with clinical care, education, and program delivery were excluded from this review. RESULTS: We identified 44 measures of research collaboration quality, which included 35 measures with reliability and some form of statistical validity reported. Most scales focused on group dynamics. We identified 89 measures of research collaboration outcomes; 16 had reliability and 15 had a validity statistic. Outcome measures often only included simple counts of products; publications rarely defined how counts were delimited, obtained, or assessed for reliability. Most measures were tested in only one venue. CONCLUSIONS: Although models of collaboration have been developed, in general, strong, reliable, and valid measurements of such collaborations have not been conducted or accepted into practice. This limitation makes it difficult to compare the characteristics and impacts of research teams across studies or to identify the most important areas for intervention. To advance the science of team science, we provide recommendations regarding the development and psychometric testing of measures of collaboration quality and outcomes that can be replicated and broadly applied across studies.
Homogeneous nucleation of colloidal melts under the influence of shearing fields

description: We study the effect of shear flow on homogeneous crystal nucleation, using Brownian Dynamics simulations in combination with an umbrella sampling like technique. The symmetry breaking due to shear results in anisotropic radial distribution functions. The homogeneous shear rate suppresses crystal nucleation and leads to an increase of the size of the critical nucleus. These observations can be described by a simple, phenomenological extension of classical nucleation theory. In addition, we find that nuclei have a preferential orientation with respect to the direction of shear. On average the longest dimension of a nucleus is along the vorticity direction, while the shortest dimension is preferably perpendicular to that and slightly tilted with respect to the gradient direction.

description: Previous studies favorably compare organic with conventional production techniques, but do not consider climatic impacts on organic crop response. Organic vegetable production is analyzed under rigorous climatic conditions in Florida. Unit production cost was reduced by organic methods in only one of seven crops. Labor-intensive organic production is commercially infeasible in the study area.
Constraining Global Changes in Temperature and Precipitation From Observable Changes in Surface Radiative Heating

description: Changes in the atmospheric composition alter the magnitude and partitioning between the downward propagating solar and atmospheric longwave radiative fluxes heating the Earth's surface. These changes are computed by radiative transfer codes in Global Climate Models, and measured with high precision at surface observation networks. Changes in radiative heating signify changes in the global surface temperature and hydrologic cycle. Here, we develop a conceptual framework using an Energy Balance Model to show that first order changes in the hydrologic cycle are mainly associated with changes in solar radiation, while that in surface temperature are mainly associated with changes in atmospheric longwave radiation. These insights are used to explain a range of phenomena including observed historical trends, biases in climate model output, and the inter-model spread in climate change projections. These results may help identify biases in future generations of climate models.

description: A one dimensional lattice model is formulated to study tapping dynamics and the long time steady distribution in granular media. The dynamics conserves the number of particles in the system, and density changes are associated to the creation and destruction of empty sites. The model is shown to be consistent with Edwards thermodynamics theory of powders. The relationship with lattice models in which the number of particles is not conserved is discussed.
