Silent heroes of the sediment: unearthing the bioremediation potential of microbes from contaminated sites
Creators: name: Dean, Rachel
Publisher: name: No Publisher Supplied
Year: 2021

description: This dissertation work aimed to assess the bioremediation potential for two contaminated sites in New Jersey, USA. The first site is the Passaic River, which is historically contaminated with the toxic chlorinated compound, 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TeCDD), among other contaminants, and the second site is a large industrial site contaminated with many toxic, recalcitrant compounds including benzene. We created anaerobic microcosms using sediments from the Passaic River and observed dechlorination, and hence detoxification, of 2,3,7,8-TeCDD to the di-chlorinated product 2,7-dichlorodibenzo-p-dioxin. In separate microcosms, we observed dechlorination of 2,7-dichlorodibenzo-p-dioxin to the non-chlorinated dibenzo-p-dioxin, which indicates that bacteria native to these sediments are capable of completely dechlorinating the toxic parent compound 2,3,7,8-TeCDD. 16S rRNA gene sequencing and qPCR revealed an increase in a phylotype, named PR_dA.O., in 2,3,7,8-TeCDD dechlorinating cultures, hinting at an active role in dechlorination. PR_dA.O. likely represents a new genus within the Dehalococcoidia class separate from Dehalogenimonas and Dehalococcoides, well-established dechlorinators. DNA from the most active 2,3,7,8-TeCDD dechlorinating bottle was shotgun sequenced to obtain reads for a metagenome. Many partial reductive dehalogenase homologous (rdh) genes were identified; however, few full length rdh could be identified. Of interest, seventeen high-coverage rdhA encoding the catalytically active portion of reductive dehalogenases were identified, most with accompanying rdhB predicted membrane anchor protein genes. These rdh genes can be candidates for heterologous expression in a more quickly growing host organism. We analyzed multidisciplinary datasets focused on a contaminated section of a large industrial site in Southern New Jersey. The data included groundwater geochemical species data, X-ray fluorescence (XRF), and 16S rRNA gene sequencing data obtained through interrogation of thin slices of an anaerobic sediment core. We hypothesized zones of biodegradation activity based on aligning data trends and potential microbial metabolisms. This study was unique in its fine-scale resolution of the data due to the separate analyses of over 300 slices of the core by collaborators. Our results suggest that an iron-reducing bacterium from a 4-inch region of the core was capable of benzene oxidation and produced the observed geochemical and contaminant profiles seen within the corresponding depth at the site.

description: Buscamos nesta apresentação, fruto dos primeiros passos de nosso estudo, considerar a doutrinação filosófica observável nas Cartas a Lucílio do autor romano Lúcio Aneu Sêneca (4 a.C.- 65 d.C.). Nessa obra, deparamo-nos com um mestre do Estoicismo que orienta seu discípulo, Lucílio, a viver de acordo com essa escola filosófica fundada no período helenístico. O processo de orientação senequeano apresenta diversos pontos notáveis, dos quais elegemos comentar brevemente três: possíveis vantagens decorrentes da escolha do gênero epistolar, no que concerne à relação mestre-discípulo; um uso constante de imagens, que ilustram as idéias apresentadas; e, finalmente, algumas questões acerca do confronto entre contemplação e ação na Filosofia, o qual incita interessantes reflexões sobre o Estoicismo em si desenvolvido em Roma daquela época.

description: Spinning neutron stars acquire a quadrupole moment due to their own rotation. This quadratic-in-spin, self-spin effect depends on the equation of state (EOS) and affects the orbital motion and rate of inspiral of neutron star binaries. We incorporate the EOS-dependent self-spin (or monopole-quadrupole) terms in the spin-aligned effective-one-body (EOB) waveform model TEOBResumS at next-to-next-to-leading (NNLO) order, together with other (bilinear, cubic and quartic) nonlinear-in-spin effects (at leading order, LO). The structure of the Hamiltonian of TEOBResumS is such that it already incorporates, in the binary black hole case, the recently computed quartic-in-spin LO term. Using the gauge-invariant characterization of the phasing provided by the function $Q_ω=ω^2/\dotω$ of $ω=2πf$ , where $f$ is the gravitational wave frequency, we study the EOS dependence of the self-spin effects and show that: (i) the next-to-leading order (NLO) and NNLO monopole-quadrupole corrections yield increasingly phase-accelerating effects compared to the corresponding LO contribution; (ii) the standard TaylorF2 post-Newtonian (PN) treatment of NLO (3PN) EOS-dependent self-spin effects makes their action stronger than the corresponding EOB description; (iii) the addition to the standard 3PN TaylorF2 post-Newtonian phasing description of self-spin tail effects at LO allows one to reconcile the self-spin part of the TaylorF2 PN phasing with the corresponding TEOBResumS one up to dimensionless frequencies $Mω\simeq 0.04-0.06$. By generating the inspiral dynamics using the post-adiabatic approximation, incorporated in a new implementation of TEOBResumS, one finds that the computational time needed to obtain a typical waveform (including all multipoles up to $\ell=8$) from 10 Hz is of the order of 0.4 sec.

description: Classification of high-dimensional low sample size (HDLSS) data poses a challenge in a variety of real-world situations, such as gene expression studies, cancer research, and medical imaging. This article presents the development and analysis of some classifiers that are specifically designed for HDLSS data. These classifiers are free of tuning parameters and are robust, in the sense that they are devoid of any moment conditions of the underlying data distributions. It is shown that they yield perfect classification in the HDLSS asymptotic regime, under some fairly general conditions. The comparative performance of the proposed classifiers is also investigated. Our theoretical results are supported by extensive simulation studies and real data analysis, which demonstrate promising advantages of the proposed classification techniques over several widely recognized methods.

description: In order to verify the existence of coherent orientations of quasars polarization vectors on very large scales, we have obtained new polarization measurements for a sample of quasars located in a given region of the three-dimensional Universe where the range of polarization position angles was predicted in advance. For this new sample, the hypothesis of uniform distribution of polarization position angles may be rejected at the 1.8% significance level on the basis of a simple binomial test. This result provides an independent confirmation of the existence of alignments of quasar polarization vectors on very large scales. In total, out of 29 polarized quasars located in this region of the sky, 25 have their polarization vectors coherently oriented. This alignment occurs at redshifts 1-2 suggesting the presence of correlations in objects or fields on Gpc scales. More global statistical tests applied to the whole sample of polarized quasars distributed all over the sky confirm that polarization vectors are coherently oriented in a few groups of 20-30 quasars. Some constraints on the phenomenon are also derived. Considering more particularly the quasars in the selected region of the sky, we found that their polarization vectors are roughly parallel to the plane of the Local Supercluster. But the polarization vectors of objects along the same line of sight at lower redshifts are not accordingly aligned. We also found that the known correlations between quasar intrinsic properties and polarization are not destroyed by the alignment effect. Several possible mechanisms are discussed, but the interpretation of this orientation effect remains puzzling.

description: In this article, we propose a new method to compute the effective properties of non-linear disordered media. We use the fact that the effective constants can be defined through the minimum of an energy functional. We express this minimum in terms of a path integral allowing us to use many-body techniques. We obtain the perturbation expansion of the effective constants to second order in disorder, for any kind of non-linearity. We apply our method to both cases of strong and weak non-linearities. Our results are in agreement with previous ones, and could be easily extended to other types of non-linear problems in disordered systems.

description: In a Quantum Walk (QW) the "walker" follows all possible paths at once through the principle of quantum superposition, differentiating itself from classical random walks where one random path is taken at a time. This facilitates the searching of problem solution spaces faster than with classical random walks, and holds promise for advances in dynamical quantum simulation, biological process modelling and quantum computation. Current efforts to implement QWs have been hindered by the complexity of handling single photons and the inscalability of cascading approaches. Here we employ a versatile and scalable resonator configuration to realise quantum walks with bright classical light. We experimentally demonstrate the versatility of our approach by implementing a variety of QWs, all with the same experimental platform, while the use of a resonator allows for an arbitrary number of steps without scaling the number of optics. Our approach paves the way for practical QWs with bright classical light and explicitly makes clear that quantum walks with a single walker do not require quantum states of light.

description: The description of general relativistic radiation hydrodynamics in spherical symmetry is presented in natural coordinate choices. For hydrodynamics, comoving coordinates are chosen, and the momentum phase space for the radiation particles is described in comoving frame four momenta. We also investigate a description of the momentum phase space in terms of particle impact parameter and energy at infinity and derive a simple approximation to the general relativistic Boltzmann equation. Further developed are, however, the exact equations in comoving coordinates, because the description of the interaction between matter and radiation particles is best described in the closely related orthonormal basis comoving with the fluid elements. We achieve a conservative and concise formulation of radiation hydrodynamics that is well suited for numerical implementation by a variety of methods. The contribution of radiation to the general relativistic jump conditions at shock fronts is discussed, and artificial viscosity is consistently included in the derivations in order to support approaches relying on this option.

description: The ultrafast formation of strongly bound excitons in two-dimensional semiconductors provide a rich platform for studying fundamental physics as well as developing novel optoelectronic technologies. While extensive research has explored the excitonic coherence, many-body interactions, and nonlinear optical properties, the potential to study these phenomena by directly controlling their coherent polarization dynamics has not been fully realized. In this work, we use a sub-10fs pulse shaper to study how temporal control of coherent exciton polarization affects the generation of four-wave mixing in monolayer WSe2 under ambient conditions. By tailoring multiphoton pathway interference, we tune the nonlinear response from destructive to constructive interference, resulting in a 2.6-fold enhancement over the four-wave mixing generated by a transform-limited pulse. This demonstrates a general method for nonlinear enhancement by shaping the pulse to counteract the temporal dispersion experienced during resonant light-matter interactions. Our method allows us to excite both 1s and 2s states, showcasing a selective control over the resonant state that produces nonlinearity. By comparing our results with theory, we find that exciton-exciton interactions dominate the nonlinear response, rather than Pauli blocking. This capability to manipulate exciton polarization dynamics in atomically thin crystals lays the groundwork for exploring a wide range of resonant phenomena in condensed matter systems and opens up new possibilities for precise optical control in advanced optoelectronic devices.

description: The propagation of an interacting particle pair in a disordered chain is characterized by a set of localization lengths which we define. The localization lengths are computed by a new decimation algorithm and provide a more comprehensive picture of the two-particle propagation. We find that the interaction delocalizes predominantly the center-of-mass motion of the pair and use our approach to propose a consistent interpretation of the discrepancies between previous numerical results.

description: We perform a combined analysis of inclusive electron scattering data from $A=3$ nuclei in the deep-inelastic and quasielastic scattering regions, using Monte Carlo analysis methods and the nuclear weak binding approximation to establish the range over which the data can be described within the same theoretical framework. Comparison with quasielastic $^3$He cross sections from SLAC and Jefferson Lab suggests that most features of the $x \gtrsim 1$ data can be reasonably well described in the impulse approximation with finite-$Q^2$ nuclear smearing functions for momentum transfers $Q^2 \gtrsim 1$ GeV$^2$. For the DIS region, we analyze the recent $^3$He to deuterium cross section ratio from the Jefferson Lab E03-103 experiment to explore the possible isospin dependence of the nuclear effects. We discuss the implications of this for the MARATHON experiment at Jefferson Lab, and outline how a Bayesian analysis of $^3$He, $^3$H and deuterium data can robustly determine the free neutron structure function.

description: This letter presents an extended analysis and a novel upper bound of the subclass of Linear Quadratic Near Potential Differential Games (LQ NPDG). LQ NPDGs are a subclass of potential differential games, for which a distance between an LQ exact potential differential game and the LQ NPDG. LQ NPDGs exhibit a unique characteristic: the smaller the distance from an LQ exact potential differential game, the closer their dynamic trajectories. This letter introduces a novel upper bound for this distance. Moreover, a linear relation between this distance and the resulting trajectory errors is established, opening the possibility for further application of LQ NPDGs.

description: In this work we study the unitary time-evolutions of quantum systems defined on infinite-dimensional separable time-dependent Hilbert spaces. Two possible cases are considered: a quantum system defined on a stochastic interval and another one defined on a Hilbert space with stochastic integration measure (stochastic time-dependent scalar product). The formulations of the two problems and a comparison with the general theory of open quantum systems are discussed. Possible physical applications of the situations considered are analyzed.

description: The interplay between disorder and quantum interference leads to a wide variety of physical phenomena including celebrated Anderson localization -- the complete absence of diffusive transport due to quantum interference between different particle trajectories. In two dimensions, any amount of disorder is thought to induce localization of all states at long enough length scales, though this may be prevented if bands are topological or have strong spin-orbit coupling. In this note, we present a simple argument providing another mechanism for disrupting localization: by tuning the underlying curvature of the manifold on which diffusion takes place. We show that negative curvature manifolds contain a natural infrared cut off for the probability of self returning paths. We provide explicit calculations of the Cooperon -- directly related to the weak-localization corrections to the conductivity -- in hyperbolic space. It is shown that constant negative curvature leads to a rapid growth in the number of available trajectories a particle can coherently traverse in a given time, reducing the importance of interference effects and restoring classical diffusive behavior even in the absence of inelastic collisions. We conclude by arguing that this result may be amenable to experimental verification through the use of quantum simulators.

description: We study interfacial instabilities between two spatially periodically sheared ideal fluids. Bloch wavefunction decompositions of the surface deformation and fluid velocities result in a nonhermitian secular matrix with an associated band structure that yields both linear oscillating and nonoscillating instabilities, enhanced near Bragg planes corresponding to the periodicity determined by converging or diverging surface flows. The instabilities persist even when the dynamical effects of the upper fluid are neglected, in contrast to the uniform shear Kelvin-Helmholtz (KH) instability. Periodic flows can also couple with uniform shear and suppress standard KH instabilities.

description: Deep Neural Networks (DNNs) have achieved unprecedented success in various applications like autonomous vehicles, speech recognition, etc. However, this success is at the cost of the huge model size, typically with hundreds of layers and millions or even billions of parameters. It is very difficult to deploy these deep neural networks on embedded devices with limited hardware resources and a tight power budget. Therefore, it is imperative to reduce the model size of deep neural networks to save both storage and computation without sacrificing their performance. To date, there are many model compression methods, however, most of them are hardware unfriendly. This thesis focuses on hardware-friendly algorithm and domain-specific hardware architecture to tackle these challenging issues. To overcome the irregularity of conventional model compression method or the complex computation incurred by the regular dense matrix, we introduce PermDNN and PermCNN. They compress the neural network with permuted diagonal matrices with highly energy-efficient hardware accelerator. Tensor-train decomposition (TTD) has a much higher compression ratio than traditional methods. However, the naive TTD computation incurs a lot of redundant computation. We propose the compact form TTD calculation which removes all the redundant computation, and a dedicated hardware-architecture accelerates this compact form TTD calculation. Considering the universal availability of the sparse neural network models, it is also important to improve the energy-efficiency of sparse DNN hardware accelerators. However, the state-of-the-art sparse CNN accelerators suffer from redundant computation, high-cost intersection, and little data reuse. GoSPA improves energy efficiency by utilizing of the property of static weight stream and the computation reordering. The evaluation shows that all of the PermDNN, PermCNN, TIE, and GoSPA achieve several times higher energy-efficient than the state-of-the-art.

description: We aim at providing the object detection community with an efficient and performant object detector, termed YOLO-MS. The core design is based on a series of investigations on how multi-branch features of the basic block and convolutions with different kernel sizes affect the detection performance of objects at different scales. The outcome is a new strategy that can significantly enhance multi-scale feature representations of real-time object detectors. To verify the effectiveness of our work, we train our YOLO-MS on the MS COCO dataset from scratch without relying on any other large-scale datasets, like ImageNet or pre-trained weights. Without bells and whistles, our YOLO-MS outperforms the recent state-of-the-art real-time object detectors, including YOLO-v7, RTMDet, and YOLO-v8. Taking the XS version of YOLO-MS as an example, it can achieve an AP score of 42+% on MS COCO, which is about 2% higher than RTMDet with the same model size. Furthermore, our work can also serve as a plug-and-play module for other YOLO models. Typically, our method significantly advances the APs, APl, and AP of YOLOv8-N from 18%+, 52%+, and 37%+ to 20%+, 55%+, and 40%+, respectively, with even fewer parameters and MACs. Code and trained models are publicly available at https://github.com/FishAndWasabi/YOLO-MS. We also provide the Jittor version at https://github.com/NK-JittorCV/nk-yolo.

description: The interface of two dissimilar materials is well known for surprises in condensed matter, and provides avenues for rich physics as well as seeds for future technological advancements. We present some exciting magnetization (M) and remnant magnetization ($μ$) results, which conclusively arise at the interface of two highly functional materials, namely the graphitic shells of a carbon nanotube (CNT) and $α$-Fe$_2$O$_3$, a Dzyaloshinskii-Moriya Interaction (DMI) driven weak ferromagnet (WFM) and piezomagnet (PzM). We show that the encapsulation inside CNT leads to a very significant enhancement in M and correspondingly in $μ$, a time- stable part of the remanence, exclusive to the WFM phase. Up to 70% of in-field magnetization is retained in the form of $μ$ at the room temperature. Lattice parameter of CNT around the Morin transition of the encapsulate exhibits a clear anomaly, confirming the novel interface effects. Control experiments on bare $α$-Fe$_2$O$_3$ nanowires bring into fore that the weak ferromagnets such as $α$-Fe$_2$O$_3$ as are not as weak, as far as their remanence and its stability with time is concerned, and encapsulation inside CNT leads to a substantial enhancement in these functionalities.
On the Coexistence in RuSr2GdCu2O8 of Superconductivity and Ferromagnetism

description: We review the reasons that make superconductivity unlikely to arise in a ferromagnet. Then, in light of the report by Tallon and collaborators that RuSr2GdCu2O8 becomes superconducting at approximately 35 K which is well below the Curie temperature of 132 K, we consider whether the objections really apply to this compound. Our considerations are supported by local spin density calculations for this compound, which indeed indicate a ferromagnetic RuO2 layer. The Ru moment resides in t_2g orbitals but is characteristic of itinerant magnetism (and is sensitive to choice of exchange-correlation potential and to the atomic positions). Based on the small exchange splitting that is induced in the Cu-O layers, the system seems capable of supporting singlet superconductivity an FFLO-type order parameter and possibly a pi-phase alternation between layers. If instead the pairing is triplet in the RuO2 layers, it can be distinguished by a spin-polarized supercurrent. Either type of superconductivity seems to imply a spontaneous vortex phase if the magnetization is rotated out of the plane.

A neighborhood level analysis of the relationship between youth engagement and gun violence
Creators: name: Thompson, Brielle Kristen
Publisher: name: No Publisher Supplied

description: Fatal gun violence poses as an unprecedented public health crisis as it ravages through communities across The United States. Several conditions serve as predictors for what this country deems the most heinous of offenses, murder. According to The Gun Violence Archive, at least, 19,223 people lost their lives to gun violence in 2020, predominantly young Black males. Homicide is the leading cause of death among black males ages 18-29. Despite this, the association of neighborhood age composition with violence has not been consistent in existing literature. This thesis will seek to explain and provide an analysis of the impact neighborhood age composition has on predicting Black versus White gun violence in four major cities in the United States, for two time periods of 2005 and 2018. While analyzing different theories related to explaining crime, I predict that the study will find that cities with large populations of minority youth with have higher levels of youth disengagement resulting in higher levels of fatal gun violence.

description: The mathematical concept of stochastic dominance was introduced to describe preference of one random gain over another. We show that for bounded gains apart from the mathematical definition there is a more natural interpretation: one gain dominates another if the expected values of a class of non-decreasing functions are larger. This class of functions includes all natural utility functions. Some special choices give the necessary conditions for stochastic dominance derived by W.H. Jean (1980, 1984). We also provide some easy to check sufficient conditions for stochastic dominance. It is argued that if the difference of the densities of two gains has n-1 sign changes and certain moment relations are satisfied, one dominates the other stochastically for order n .

description: Given a finite abelian group $G$ and cyclic subgroups $A$, $B$, $C$ of $G$ of the same order, we find necessary and sufficient conditions for $A$, $B$, $C$ to admit a common transversal for the cosets they afford. For an arbitrary number of cyclic subgroups we give a sufficient criterion when there exists a common complement. Moreover, in several cases where a common transversal exists, we provide concrete constructions.

description: Feed efficiency has become an increasingly important research topic in recent years. As feed costs rise and the environmental impacts of agriculture become more apparent, improving the efficiency with which dairy cows convert feed to milk is increasingly important. However, feed intake is expensive to measure accurately on large populations, making the inclusion of this trait in breeding programs difficult. Understanding how the genetic parameters of feed efficiency and traits related to feed efficiency vary throughout the lactation period is valuable to gain understanding into the genetic nature of feed efficiency. This study used 121,226 dry matter intake (DMI) records, 120,500 energy-corrected milk (ECM) records, and 98,975 metabolic body weight (MBW) records, collected on 7,440 first-lactation Holstein cows from 6 countries (Canada, Denmark, Germany, Spain, Switzerland, and the United States), from January 2003 to February 2022. Genetic parameters were estimated using a multiple-trait random regression model with a fourth-order Legendre polynomial for all traits. Weekly phenotypes for DMI were re-parameterized using linear regressions of DMI on ECM and MBW, creating a measure of feed efficiency that was genetically corrected for ECM and MBW, referred to as genomic residual feed intake (gRFI). Heritability (SE) estimates varied from 0.15 (0.03) to 0.29 (0.02) for DMI, 0.24 (0.01) to 0.29 (0.03) for ECM, 0.55 (0.03) to 0.83 (0.05) for MBW, and 0.12 (0.03) to 0.22 (0.06) for gRFI. In general, heritability estimates were lower in the first stage of lactation compared with the later stages of lactation. Additive genetic correlations between weeks of lactation varied, with stronger correlations between weeks of lactation that were close together. The results of this study contribute to a better understanding of the change in genetic parameters across the first lactation, providing insight into potential selection strategies to include feed efficiency in breeding programs.

description: I present an extension of the phase distance correlation periodogram to two-dimensional astrometric data. I show that this technique is more suitable than previously proposed approaches to detect eccentric Keplerian orbits, and that it overcomes the inherent bias of the joint periodogram to circular orbits. This new technique might prove to be essential in the context of future astrometric space missions such as Theia.

description: We consider the Hall effect in a system of weakly coupled one-dimensional chains with Luttinger interaction within each chain. We construct a perturbation theory in the inter-chain hopping term and find that there is a power law dependence of the Hall conductivity on the magnetic field with an exponent depending on the interaction constant. We show that this perturbation theory becomes valid if the magnetic field is sufficiently large.
