description: Aim of this research paper was to investigate the potential of fish scales as an adsorbent for crystal violet dye exclusion from wastewater and to optimize various adsorption parameters for maximum adsorption of dye. Parameters studied were solution pH, adsorbent dose, contact time, dye concentration, and temperature. Results showed maximum percentage degradation, i.e., 90% under optimized conditions such as pH 12 solution, 0.4 g adsorbent dose, with 40 min of exposure time and 40 ppm of dye concentration at 10 °C solution temperature. Adsorbent was characterized using FTIR, and SEM techniques to explore the functionality and to study morphology of adsorbent, respectively. Results confirmed that carboxyl, amino, phosphate, and sulfonate groups and heterogeneous adsorbent surface was accountable for crystal violet dye adsorption on fish scales. pHpzc of the fish scale was 8. Adsorption isotherms such as Langmuir, Freundlich, and D-R isotherm models were also investigated. Contact time data was applied to various kinetic models, i.e., pseudo-first order, and pseudo-second order kinetic models. Thermodynamic study was also investigated. Results confirmed that experimental data fitted well to Freundlich isotherm model (R2 = 0.9983) and pseudo second order kinetic model (R2 = 0.9970) as ARE error analysis values of these models were 1.191692 E + 06 and −160.66, respectively (lower than that of other models. Computed ΔG and ΔH values confirmed adsorption process to be spontaneous and of endothermic kind. Applicability of established procedure with tap water was 78% and regeneration percentage was 72% which showed the effectiveness of fish scales powder for removal of crystal violet dye from wastewater.

description: Abstract: "Pipelining is a widely used technique that query execution engines employ to improve individual query execution times. In recently proposed settings, pipelining is used as an alternative to materialization to evaluate query plan graphs, where nodes in a query plan can have multiple parents. Such scenarios include shared table scans, runtime operator sharing, parallel sorting, and pipelined Multi-Query Optimization (MQO) plans. While pipelining in query graphs can increase performance, it can also lead to runtime deadlocks. The existing deadlock solutions focus on total deadlock prevention by statically deciding between pipelining and materialization, and apply only to MQO. The lack of runtime information leads to highly conservative decisions. Formally, this conservatism makes it NP-hard to find an optimal pipelining strategy that materializes a minimum cost set of nodes in a query graph. We propose a novel dynamic scheme for detecting and resolving deadlocks in pipelined query graphs. Instead of statically determining what nodes to materialize, we pipeline every pipelinable operator in the query plan, resolving deadlock when it arises by materialization. At runtime, more information about producer-consumer behavior is available and as a result, the problem of detecting and resolving deadlock becomes polynomial time solvable, where each particular deadlock resolution is of minimum cost. Our techniques are applicable to any system that uses pipelined query graphs. An evaluation on TPC-H and Wisconsin benchmarks demonstrates cases where our approach eliminates all unnecessary materializations, and minimizes the overall query execution cost."

description: Because of the timing, complexity, and asynchronicity
challenges common in modular robot software we
have recently begun to explore new programming models for
modular robot ensembles. In this paper we apply two of those
models to a metamodule-based shape planning algorithm and
comment on the differences between the two approaches. Our
results suggest that declarative programming can provide several
advantages over more traditional imperative approaches,
and that the differences between declarative programming
styles can themselves contribute leverage to different parts of
the problem domain.

description: At the low Landau filling factor $(ν)$ termination of the fractional quantum Hall effect (FQHE) series, two-dimensional electron systems (2DESs) exhibit an insulating phase that is understood as a form of pinned Wigner solid. Here we use microwave spectroscopy to probe the transition to the insulator for a wide quantum well (WQW) sample that can support single-layer or bilayer states depending on its overall carrier density, $n$. We find the insulator exhibits a resonance, which is characteristic of a bilayer solid. The resonance also reveals a pair of transitions within the solid, which are not accessible to dc transport measurements. As $n$ is biased deeper into the bilayer solid regime, the resonance grows in specific intensity, and the transitions within the insulator disappear. These behaviors are suggestive of a picture of the insulating phase as an emulsion of liquid and solid components.

description: In this study, the phosphazene chitosan derivative was manufactured and characterized. adsorption of molybdenum (Mo) from solutions using prepared working material as sorbent was examined. Nuclear magnetic resonance spectroscopy (1HNMR), Carbon-13 (13CNMR) nuclear magnetic resonance, Gas Chromatography–Mass Spectrometry (GC–MS), Phosphorus-31 nuclear magnetic resonance (31P-NMR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller analysis (BET surface area) and Fourier-transform infrared spectroscopy (FTIR) were used to characterize and confirm the prepared adsorbent. Many variables, including pH of the aqueous solution, the amount of adsorbent dosed, initial concentration of Mo(VI), contact time, and temperature were examined using the batch adsorption technique. When Mo(VI) is exposed to foreign ions, its desorption behavior changes. (Cr6+, Cl−, Co2+, Fe3+, and sulfate) were investigated. Cr6+ had a greater impact on the adsorption process in compared with other foreign ions. The maximum capability for Mo(VI) adsorption on the created adsorbent was 305.07 ± 2.36 mg/g, which was obtained at room temperature. The adsorption isotherms were best fitted with the Freundlich isotherm model. The kinetic data fitted well with the pseudo-second-order equation. The thermodynamic studies found that the adsorption was an exothermic and spontaneous process in nature.

description: The Johnson-Lindenstrauss lemma provides a way to map a number of points in high-dimensional space into a low-dimensional space, with only a small distortion of the distances between the points. The proofs of the lemma are non-constructive: they show that a random mapping induces small distortions with high probability, but they do not construct the actual mapping. In this paper, we provide a procedure that constructs such a mapping deterministically in time almost linear in the number of distances to preserve times the dimension of the original space. We then use that result (together with Nisan's pseudorandom generator) to obtain an efficient derandomization of several approximation algorithms based on semidefinite programming.

description: We derive scalar effective field theories - Lagrangians, symmetries, and all - from on-shell scattering amplitudes constructed purely from Lorentz invariance, factorization, a fixed power counting order in derivatives, and a fixed order at which amplitudes vanish in the soft limit. These constraints leave free parameters in the amplitude which are the coupling constants of well-known theories: Nambu-Goldstone bosons, Dirac-Born-Infeld scalars, and Galileons. Moreover, soft limits imply conditions on the Noether current which can then be inverted to derive Lagrangians for each theory. We propose a natural classification of all scalar effective field theories according to two numbers which encode the derivative power counting and soft behavior of the corresponding amplitudes. In those cases where there is no consistent amplitude, the corresponding theory does not exist.

description: Among the widely studied superconducting iron-pnictide compounds belonging to the Ln1111 family (with Ln a lanthanide), a systematic investigation of the crossover region between the superconducting and the antiferromagnetic phase for the Ln = Nd case has been missing. We fill this gap by focusing on the intermediate doping regime of NdFeAsO(1-x)F(x) by means of dc-magnetometry and muon-spin spectroscopy measurements. The long-range order we detect at low fluorine doping is replaced by short-range magnetic interactions at x = 0.08, where also superconductivity appears. In this case, longitudinal-field muon-spin spectroscopy experiments show clear evidence of slow magnetic fluctuations that disappear at low temperatures. This fluctuating component is ascribed to the glassy-like character of the magnetically ordered phase of NdFeAsO at intermediate fluorine doping.

description: There has been a resurgence of interest in dataflow architectures, because of their potential for exploiting parallelism with low overhead. In this paper we analyze the performance  of a class of  static dataflow machines on integer media and  control-intensive programs and we explain why a dataflow machine, even with unlimited resources, does not always outperform a superscalar processor on general-purpose codes, under the assumption that both machines take the same time to execute basic operations. We compare a program-specific dataflow machine with unlimited parallelism to a superscalar processor running the same program. While the dataflow machines provide very good performance on most data-parallel programs, we show that the dataflow machine cannot always take advantage of the available parallelism. Using the dynamic critical path we investigate the mechanisms used by superscalar processors to provide a performance advantage and their impact on a dataflow model

New Statistical Learning Methods for Multiple High Dimensional Datasets
Creators: name: Lee, Wonyul
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: In this dissertation, we design several statistical learning methods for analyzing multiple high-dimensional datasets. Our focus is on multiple response regression and inverse covariance matrix estimation. Multivariate regression is a common statistical tool for practical problems. Many multivariate regression techniques are designed for univariate response cases. For problems with multiple response variables available, one common approach is to apply the univariate response regression technique separately on each response variable. Although it is simple and popular, the univariate response approach ignores the joint information among response variables. We propose several methods for utilizing joint information among response variables in a penalized likelihood framework. The proposed methods provide sparse estimators for the conditional inverse covariance matrix of response vector given explanatory variables as well as sparse estimators of regression coefficient matrix. Estimation of inverse covariance matrices is important in various areas of statistical analysis. The task of estimating multiple inverse covariance matrices sharing some common structure is considered. In this case, estimating each matrix separately can be suboptimal as it ignores potential common structure. We propose a new approach to parameterize each inverse covariance matrix as a sum of common and unique components and jointly estimate multiple inverse covariance matrices in a constrained L1 minimization framework. Theoretical properties of the new methods are explored. Simulated examples and applications to a glioblastoma multiforme cancer data demonstrate competitive performance of the proposed methods.

description: Abstract: "Given a formula [Phi] in quantifier-free Presburger arithmetic, it is well known that, if there is a satisfying solution to [Phi], there is one whose size, measured in bits, is polynomially bounded in the size of [Phi]. In this paper, we consider a special class of quantifier-free Presburger formulas in which most linear constraints are separation (difference-bound) constraints, and the non-separation constraints are sparse. This class has been observed to commonly occur in software verification problems. We derive a new solution bound in terms of parameters characterizing the sparseness of linear constraints and the number of non-separation constraints, in addition to traditional measures of formula size. In particular, the number of bits needed per integer variable is linear in the number of non-separation constraints and logarithmic in the number and size of non-zero coefficients in them, but is otherwise independent of the total number of linear constraints in the formula. The derived bound can be used in a decision procedure based on instantiating integer variables over a finite domain and translating the input quantifier-free Presburger formula to an equi-satisfiable Boolean formula, which is then checked using a Boolean satisfiability solver. We present empirical evidence indicating that this method can greatly outperform other decision procedures."
Enhanced thermionic-dominated photoresponse in graphene Schottky junctions

description: Vertical heterostructures of van der Waals materials enable new pathways to tune charge and energy transport characteristics in nanoscale systems. We propose that graphene Schottky junctions can host a special kind of photoresponse which is characterized by strongly coupled heat and charge flows that run vertically out of the graphene plane. This regime can be accessed when vertical energy transport mediated by thermionic emission of hot carriers overwhelms electron-lattice cooling as well as lateral diffusive energy transport. As such, the power pumped into the system is efficiently extracted across the entire graphene active area via thermionic emission of hot carriers into a semiconductor material. Experimental signatures of this regime include a large and tunable internal responsivity ${\cal R}$ with a non-monotonic temperature dependence. In particular, ${\cal R}$ peaks at electronic temperatures on the order of the Schottky potential $ϕ$ and has a large upper limit ${\cal R} \le e/ϕ$ ($e/ϕ=10\,{\rm A/W}$ when $ϕ= 100\,{\rm meV}$). Our proposal opens up new approaches for engineering the photoresponse in optically-active graphene heterostructures.

Domestic Activities and Household Variation at Catawba New Town ca. 1790-1820
Creators: name: Shebalin, Theresa McReynolds

description: The Catawba Nation's endurance to the present day can be attributed in large part to its members' creative adaptations to the dynamic sociopolitical, economic, and demographic circumstances of the eighteenth and early nineteenth centuries. Archaeological data from the New Town community indicate that during the post-Revolutionary War Federal Period (ca. 1781-1820), Catawba families employed a variety of different social and economic strategies to survive in a homeland that had become dominated by Anglo-American yeoman farmers. My research explores this evidence for intracommunity variability at New Town and its implications. It integrates archaeological and ethnohistorical evidence to reconstruct the organization and use of domestic space by individual Catawba households. The results reveal that families living in the southern hamlet at New Town embraced western social and economic ideas and practices to a greater extent than their northern neighbors, who may have intentionally emphasized or even exaggerated differences between their lifestyles and those of their Anglo-American neighbors.

description: Checkpointing is the predominant storage driver in today's petascale supercomputers and is expected to remain as such in tomorrow's exascale supercomputers. Users typically prefer to checkpoint into a shared file yet parallel file systems often perform poorly for shared file writing. A powerful technique to address this problem is to transparently transform shared file writing into many exclusively written as is done in ADIOS and PLFS. Unfortunately, the metadata to reconstruct the fragments into the original file grows with the number of writers. As such, the current approach cannot scale to exaflop supercomputers due to the large overhead of creating and reassembling the metadata. In this paper, we develop and evaluate algorithms by which patterns in the PLFS metadata can be discovered and then used to replace the current metadata. Our evaluation shows that these patterns reduce the size of the metadata by several orders of magnitude, increase the performance of writes by up to 40 percent, and the performance of reads by up to 480 percent. This contribution therefore can allow current checkpointing models to survive the transition from petato exascale.
Investigating transcranial alternating current stimulation for apathy in Huntington's disease

description: Huntington’s disease (HD) is an inherited neurodegenerative disease. Severely reduced motivation, referred to as “apathy”, is a prevalent symptom in HD, with no effective treatments currently available. It presents challenges for people early in their disease course who are otherwise physically and cognitively able to participate in most home, work, and social activities. This thesis demonstrated the safety and acceptability of transcranial alternating current stimulation (tACS) (a type of mild, non-invasive brain stimulation) for people with HD, and generated preliminary evidence of tACS as a means of targeting the underlying brain changes associated with apathy in HD.

description: Magnetite (Fe3O4) nanoparticles were synthesized by the ultrasound assisted co-precipitation method. The synthesized nanoparticles were thoroughly characterized by various analytical tools including XRD, FESEM & TEM, VSM, BET, and FTIR. It was indicated that Fe3O4 nanoparticles have cubic structure. The size of spherical-shape Fe3O4 particles ranges from 10 to 15 nm. The Fe3O4 magnetic nanoparticles were applied as a magnetic adsorbent to remove Congo red from aqueous solution. It is assumed that the adsorption process follows the pseudo-second-order kinetics equation. Equilibrium data fits well with Langmuir model. The maximum adsorption capacity is of 169.8 mg/g. This suggests that the synthesized magnetic nanoparticles could be a promising adsorbent for organic dyes removal in aqueous solutions.

description: Very faint X-ray binaries (VFXBs), defined as having peak luminosities Lx of 10^34-10^36 erg/s, have been uncovered in significant numbers, but remain poorly understood. We analyse three published outburst light curves of two transient VFXBs using the exponential and linear decay formalism of King and Ritter (1998). The decay timescales and brink luminosities suggest orbital periods of order 1 hour. We review various estimates of VFXB properties, and compare these with suggested explanations of the nature of VFXBs. We suggest that: 1) VFXB outbursts showing linear decays might be explained as partial drainings of the disc of "normal" X-ray transients, and many VFXB outbursts may belong to this category; 2) VFXB outbursts showing exponential decays are best explained by old, short-period systems involving mass transfer from a low-mass white dwarf or brown dwarf; 3) persistent (or quasi-persistent) VFXBs, which maintain an Lx of 10^34-10^35 erg/s for years, may be explained by magnetospheric choking of the accretion flow in a propeller effect, permitting a small portion of the flow to accrete onto the neutron star's surface. We thus predict that (quasi-)persistent VFXBs may also be transitional millisecond pulsars, turning on as millisecond radio pulsars when their Lx drops below 10^32 erg/s.

description: Cancer-associated fibroblasts (CAFs) and the associated extracellular matrix (ECM) constitute a significant part of the tumour microenvironment (TME), playing an important role in the invasive potential of the tumour. The alignment of CAFs and the corresponding ECM which they produce and organise is linked with increased cancer invasion. Additionally, massive variation in the physical architecture of the ECM is observed in both normal and pathological tissues for example swirling, diffuse or porous patterns. How these mesoscale patterns arise remains largely unexplored. An agent-based flocking model was developed to investigate CAF properties and their involvement in emergent alignment. The model established that aligning cells had a requirement of highly persistent migration coupled with an active cell-cell collision guidance mechanism. The model predicted that alignment was a fragile state which could be easily destroyed in a heterogeneous population. These findings were confirmed experimentally. The model was then extended to include a second underlying layer of ECM fibres that the CAFs could produce, degrade and rearrange but were also instructed to follow, constituting a CAF-ECM feedback loop. This mechanism was capable of generating diverse matrix patterns, reminiscent of those seen in vivo. The model was challenged to unpick the process of interconversion between matrix patterns as seen in cancer, wound healing and ageing, which it elucidated with considerable success. Finally, clinical samples of ECM were quantified to establish if certain metrics of ECM architecture could be useful clinical prognostic factors. Early results suggest this to be true. Matrix patterns were quantified by a carefully constructed software pipeline suitable for use by other researchers on versatile data samples.

Adapting Mixture Models to Take into Account Measurement Non-Invariance

description: Researchers in the social sciences often use finite mixture models to find clusters of individuals on the basis of patterns of indicators. Though covariates are often incorporated in mixture models, it is most often assumed that these covariates exclusively affect class membership, rather than directly impacting the indicators themselves. Violation of this assumption indicates that the measurement of the latent classes by a given indicator is not constant across all individuals. Such violations, known as differential item functioning (DIF), have been well-studied in models for continuous latent variables, but virtually unexamined in models for categorical latent variables. The current study extends the analytic and testing framework developed in continuous latent variable models to the case of latent class analysis. First, a Monte Carlo simulation systematically examined the effects of omitted DIF on mixture model results, as well as the performance of tests to detect DIF. In the presence of DIF in the data-generating model, the omission of these effects in the fitted model was associated with overestimation of the number of classes, as well as biased estimates of covariate effects on class membership and model-implied endorsement probabilities, particularly when classes were poorly separated and DIF was large. Including DIF in the model, even if the nature of this DIF was misspecified, mitigated this bias considerably. Standard model-based procedures drawn from the continuous latent variable modeling literature were shown to detect DIF with high sensitivity and specificity. Finally, DIF was examined in an application of latent class analysis to alcohol use disorder (AUD) diagnostic criteria in an undergraduate sample. Researchers are advised to test comprehensively for DIF in applications of mixture models, in order to ensure that the results obtained are truly applicable to all individuals under study.

description: The nature of ultra-luminous X-ray sources (ULXs) has long been plagued by an ambiguity about whether the central compact objects are intermediate-mass (IMBH, >~ 10^3 M_sun) or stellar-mass (a few tens M_sun) black holes (BHs). The high luminosity (~ 10^39 erg/s) and super-soft spectrum (T ~ 0.1 keV) during the high state of the ULX source X-1 in the galaxy M101 suggest a large emission radius (>~ 10^9 cm), consistent with being an IMBH accreting at a sub-Eddington rate. However, recent kinematic measurement of the binary orbit of this source and identification of the secondary as a Wolf-Rayet star suggest a stellar-mass BH primary with a super-Eddington accretion. If that is the case, a hot, optically thick outflow from the BH can account for the large emission radius and the soft spectrum. By considering the interplay of photons' absorption and scattering opacities, we determine the radius and mass density of the emission region of the outflow and constrain the outflow mass loss rate. The analysis presented here can be potentially applied to other ULXs with thermally dominated spectra, and to other super-Eddington accreting sources.

description: A deterministic finite automaton (DFA) of $n$ states over a $k$-letter alphabet can be seen as a digraph with $n$ vertices which all have exactly $k$ labeled out-arcs ($k$-out digraph). In 1973 Grusho first proved that with high probability (whp) in a random $k$-out digraph there is a strongly connected component (SCC) of linear size that is reachable from all vertices, i.e., a giant. He also proved that the size of the giant follows a central limit law. We show that whp the part outside the giant contains at most a few short cycles and mostly consists of overlapping tree-like structures. Thus the directed acyclic graph (DAG) of a random $k$-out digraph is almost the same as the digraph with the giant contracted into one vertex. These findings lead to a new, concise and self-contained proof of Grusho's theorem. This work also contains some other results including the structure outside the giant, the phase transition phenomenon in strong connectivity, the typical distance, and an extension to simple digraphs.

description: The g-C3N4 (GCN) adsorbent with two different morphologies, coral (CGCN) and nano fiber (GCNNF), was synthesized and recruited for extraction and preconcentration of lead and copper metal ions by effervescent salt-assisted dispersive micro solid phase extraction procedure. The structures of the two adsorbents were affirmed by Fourier-transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy and Brunauer–Emmett–Teller analyses. The factors affecting the extraction efficiency were carefully studied and the optimum values of the parameters for both adsorbents were pH 6.5, adsorbent dosage 8 mg, desorption time 3 min, and the elution solvent 300 μL of 2 mol L−1 of HNO3. The detection limits of Pb(II (and Cu(II) ions for CGCN were 0.9 and 0.3 μgL−1 and for GCNNF were 1.56 and 0.7 μgL−1, respectively. The percent relative standard deviations were obtained to be 1.32% and 2.23% for CGCN (n = 3) and 1.24% and 2.29% for GCNNF (n = 3), respectively for the lead and copper metal ions. In addition, the adsorbents could be used up to 7 times without an imperative reduction in the percentages of analytes recovery. Finally, the performance of CGCN and GCNNF were used for preconcentrate of lead and copper ions in honey, canned fish, and human hair samples.

description: Recent experiments have demonstrated sub decoherence time control of individual single-electron orbital qubits. Here we propose a quantum dot based scheme for generation and detection of pairs of orbitally entangled electrons on a timescale much shorter than the decoherence time. The electrons are entangled, via two-particle interference, and transferred to the detectors during a single cotunneling event, making the scheme insensitive to charge noise. For sufficiently long detector dot lifetimes, cross-correlation detection of the dot charges can be performed with real-time counting techniques, opening up for an unambiguous short-time Bell inequality test of orbital entanglement.

description: Neutral red (NR) and safranin-O (SO) dyes are used in industrial processes, which their inappropriate disposal in surface waters causes negative impacts. Alternative techniques have been investigated for the complete removal of dyes, in which the adsorption presents itself as a feasible option, especially when low-cost adsorbents obtained from industrial waste are used, such as soybean hulls (SBH). This study proposed the use of SBH for the adsorption of NR and SO dyes. The characterization showed heterogeneous and porous morphology with predominantly negative surface charges, which favored the fixation of the cationic dyes. The comparative study of SO and NR adsorption onto SBH and commercial granular activated carbon confirmed the good performance of the biosorbent material. The maximum adsorption capacities were 287.30 and 221.74 mg g−1 for NR and SO onto SBH, respectively. The equilibrium time was reached in 90 minutes for both dyes. The experimental data was adjusted to the Langmuir and pseudo-second-order models. Thermodynamics inferred endothermic, spontaneous and reversible characteristics to adsorptive processes. The main proposed adsorption mechanisms were hydrogen bonds, π-interactions and electrostatic interactions. The regeneration study showed the possibility of reusing SBH for 6 cycles, and the effect of ionic strength found that the adsorption efficiency was not reduced. Therefore, SBH demonstrated versatility and efficiency in the removal of cationic dyes from wastewater, evidencing its industrial applicability.
