description: We present a study of spectroscopy of SU(4) lattice gauge theory coupled to two flavors of Dirac fermions in the anti-symmetric two index representation. The fermion representation is real, and the pattern of chiral symmetry breaking is SU(2Nf) -> SO(2Nf) with Nf flavors of Dirac fermions. It is an interesting generalization of QCD, for several reasons: it allows direct exploration of an alternate large Nc expansion, it can be simulated at non-zero chemical potential with no sign problem, and several UV completions of composite Higgs systems are built on it. We present preliminary results on the baryon and meson spectra of the theory and compare them with SU(3) results and with expectations for large Nc scaling.

description: Immaculate Heart of Mary Church has sat nestled on a narrow street halfway up Pittsburgh's Polish Hill since 1904. This Polish ethnic church is difficult to miss for people driving just below the Hill or in any aerial photography of Pittsburgh. Immaculate Heart's size and ornate decorations overwhelm its surrounding working class environment. Modeled after the Basilica in Rome, her three prominent domes stand as beacons to all Pittsburgh, constantly reminding the Steel City of its Eastern European and Catholic heritage. As the church's physical appearance draws attention away from the rest of Polish Hill, Immaculate Heart of Mary Church acts as the focal point of Polish Hill's community. It represents the heart of the Polish Americans' lives. Who are the people that struggled to build this magnificent monument to God amid an urban working class environment and how has their community developed since then?
Stein neighborhood bases of embedded strongly pseudoconvex domains and approximation of mappings

description: In this paper we construct a Stein neighborhood basis for any compact subvariety $A$ with strongly pseudoconvex boundary $bA$ and Stein interior $A\backslash bA$ in a complex space $X$. This is an extension of a well known theorem of Siu. When $A$ is a complex curve, our result coincides with the result proved by Drinovec-Drnovšek and Forstnerič. We shall adapt their proof to the higher dimensional case, using also some ideas of Demailly's proof of Siu's theorem. For embedded strongly pseudoconvex domain in a complex manifold we also find a basis of tubular Stein neighborhoods. These results are applied to the approximation problem for holomorphic mappings.

description: Written in Python and utilising ParselTongue to interface with the Astronomical Image Processing System (AIPS), the e-MERLIN data reduction pipeline is intended to automate the procedures required in processing and calibrating radio astronomy data from the e-MERLIN correlator. Driven by a plain text file of input parameters, the pipeline is modular and can be run in stages by the user, depending on requirements. The software includes options to load raw data, average in time and/or frequency, flag known sources of interference, flag more comprehensively with SERPent, carry out some or all of the calibration procedures including self-calibration), and image in either normal or wide-field mode. It also optionally produces a number of useful diagnostic plots at various stages so that the quality of the data can be assessed. The software is available for download from the e-MERLIN website or via Github.

description: Anisotropic properties of single crystals of SrPt$_{3}$P were studied using London penetration depth and electrical resistivity measurements. The upper critical field, $H_{c2}(T)$, was determined from four-probe electrical resistivity measurements for three orthogonal directions of a magnetic field with respect to the crystal. The London penetration depth, $λ(T)$, was determined from the magnetic susceptibility of the Meissner-London state measured using a tunnel-diode resonator technique. Whereas $H_{c2}(T)$ and the normal-state $ρ(T)$ are practically identical for all three magnetic field orientations, the London penetration depth shows significant unidirectional anisotropy. The low-temperature $λ(T)$ is exponentially attenuated when a small excitation radiofrequency magnetic field, $H_{rf}$, is applied along the $c"-$direction, in which case screening currents flow in the $a"b"-$ plane, while for the other two orientations, $H_{rf}\parallel a"$ and $H_{rf}\parallel b"$, the London penetration depth shows a much weaker, $λ(T)\sim T^{2}$, variation. Such unusual and contrasting behavior of the two anisotropies, $γ_{H}\left(T\right)=H_{c2,ab}/H_{c2,c}=ξ_{ab}/ξ_{c}$ and $γ_λ\left(T\right)=λ_{c}/λ_{ab}$, imposes significant constraints on the possible order parameter. Although our measurements are insufficient to derive conclusively the superconducting gap anisotropy, qualitatively, order parameter with two point nodes and a modulation in the perpendicular direction is consistent with the experimental observations.

description: Catalytically active macromolecules are envisioned as key building blocks in development of artificial nanomotors. However, theory and experiments report conflicting findings regarding their dynamics. The lack of consensus is mostly caused by a limited understanding of specifics of self-propulsion mechanisms at the nanoscale. Here, we study a generic model of a self-propelled nanoparticle that does not rely on a particular mechanism. Instead, its main assumption is the fundamental symmetry of microscopic dynamics of chemical reactions: the principle of microscopic reversibility. Significant consequences of this assumption arise if we subject the particle to an action of an external time-periodic force. The particle diffusion coefficient is then enhanced compared to the unbiased dynamics. The enhancement can be controlled by the force amplitude and frequency. We also derive the power spectrum of particle trajectories. Among new effects stemming from the microscopic reversibility are the enhancement of the spectrum at all frequencies and sigmoid-shaped transitions and a peak at characteristic frequencies of rotational diffusion and external forcing. The microscopic reversibility is a generic property of a broad class of chemical reactions, therefore we expect that the presented results will motivate new experimental studies aimed at testing of our predictions. This could provide new insights into dynamics of catalytic macromolecules.

description: Youth victimization in schools remains a fervent public health issue, despite increased awareness of this issue, and this is especially true for marginalized populations like lesbian, gay, bisexual, transgender, and queer (LGBTQ) youth. Youth violence has been studied widely, but less research has sought to understand factors protective of violence victimization, particularly protective factors shared across multiple forms of violence. In the current study, we utilized latent class analysis to test patterns of three types of victimization: peer victimization (PV), homophobic name-calling victimization (HNCV), and sexual harassment victimization (SHV). In addition, we tested protective factors associated with experiencing these types of violence. Our sample included 4778 9–11th graders in the United States, of which about 15% identified as LGBTQ. Three unique classes of victimization emerged, suggesting that concurrent forms of violence occur among some groups of adolescents. LGBTQ youth were more likely to be members of classes which demonstrated higher levels of victimization. Consistent with previous literature, medical access, counseling access, family support, peer support, and spirituality emerged as significant protective factors associated with a lower risk of victimization. We discuss the implications of our findings with specific attention to protecting the wellbeing of SGM youth.

description: Reliable systems health management is an important research area of NASA. A health management system that can accurately and quickly diagnose faults in various on-board systems of a vehicle will play a key role in the success of current and future NASA missions. We introduce in this paper the ProDiagnose algorithm, a diagnostic algorithm that uses a probabilistic approach, accomplished with Bayesian Network models compiled to Arithmetic Circuits, to diagnose these systems. We describe the ProDiagnose algorithm, how it works, and the probabilistic models involved. We show by experimentation on two Electrical Power Systems based on the ADAPT testbed, used in the Diagnostic Challenge Competition (DX 09), that ProDiagnose can produce results with over 96% accuracy and < 1 second mean diagnostic time.

description: The nucleon-deuteron radiative capture process is investigated using the chiral nuclear potentials and the electromagnetic currents developed by the Bochum-Bonn group. While the strong interaction is taken up to the next-to-next-to-leading order, the electromagnetic current consists of a single nucleon current, the leading one-pion exchange one and is supplemented by contributions from the long-range two-pion exchange current at next-to-leading-order. The theoretical predictions for the cross sections as well as analyzing powers show strong dependence on the values of regularization parameters. Only small effects of the three-nucleon force and the long-range two-pion exchange current are observed. The dependence on the choice of regularization parameters results in a big theoretical uncertainty and clearly points to the necessity to include corrections from higher orders of the chiral expansion both for the nuclear forces and currents.

description: Teaching is an exercise in problem solving. Every moment, a teacher must consider questions of what to teach and how to teach it, based on the subject matter, the students' current understanding of the material, and new issues that students bring to the class. Teacher planning is a complex skill consisting of assembling schemas into sequences that meet specific goals, assembling these goals into sequences that will meet higher teaching objectives, and accomplishing the latter two within the constraints of the total system. Continually, teachers must balance student needs with the syllabus, while remaining "flexible, responsive, and consistent" (Leinhardt 1989).

description: Primary ciliary dyskinesia (PCD) is an incurable, rare, inherited, chronic condition. Treatment includes the regular clearing of airway mucus, aggressive treatment of infections and management of hearing loss. Caregiver burden has not been explored, hence we interviewed 18 mothers and 6 fathers of children under 6 years to understand the impact of diagnostic testing and implications of a positive diagnosis. Interviews were transcribed and thematically analysed and five key themes were identified. These included the parents’ experiences following child’s diagnosis, impact of child’s treatment regimen on parent, impact of child’s health status on parent, parent’s coping strategies, and parental concerns for the future. Parents described their diagnostic journey, with the findings revealing how a lack of awareness among clinicians of the PCD symptom pattern can lead to a delayed diagnosis. Parents discussed the emotional and practical impact of a PCD diagnosis and the coping strategies employed to deal with challenges arising following a diagnosis. Parents use a variety of different lifestyle changes to accommodate their child’s treatment regimen and to cope with disruptive life events such as the COVID-19 pandemic. This study provides valuable insights into parental adjustment and adaptation to a PCD diagnosis and management regimen. Going forward, this research highlights the need for integrated social care for PCD patients and their families.

Regulation of the Innate Immune Response during the Human Papillomavirus Life Cycle

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2022

description: High-risk human papillomaviruses (HR HPVs) are associated with multiple human cancers and comprise 5% of the human cancer burden. Although most infections are transient, persistent infections are a major risk factor for cancer development. The life cycle of HPV is intimately linked to epithelial differentiation. HPVs establish infection at a low copy number in the proliferating basal keratinocytes of the stratified epithelium. In contrast, the productive phase of the viral life cycle is activated upon epithelial differentiation, resulting in viral genome amplification, high levels of late gene expression, and the assembly of virions that are shed from the epithelial surface. Avoiding activation of an innate immune response during the course of infection plays a key role in promoting viral persistence as well as completion of the viral life cycle in differentiating epithelial cells. This review highlights the recent advances in our understanding of how HPVs manipulate the host cell environment, often in a type-specific manner, to suppress activation of an innate immune response to establish conditions supportive of viral replication.
Power-law decay of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state

description: The hydrodynamic part of the velocity autocorrelation function of a granular fluid in the homogeneous cooling state has been calculated by using mode-coupling theory for a finite system with periodic boundary conditions. The existence of the shearing instability, leading to a divergent behavior of the velocity flow fluctuations, is taken into account. A time region in which the velocity autocorrelation function exhibits a power law decay, when time is measured by the number of collisions per particle, has been been identified. Also the explicit form of the exponential asymptotic long time decay has been obtained. The theoretical prediction for the power law decay is compared with molecular dynamics simulation results, and a good agreement is found, after taking into account finite size corrections. The effects of approaching the shearing instability are also explored.
Runaway dynamics in disruptions with current relaxation

description: The safe operation of tokamak reactors requires a reliable modeling capability of disruptions, and in particular the spatio-temporal dynamics of associated runaway electron currents. In a disruption, instabilities can break up magnetic surfaces into chaotic field line regions, causing current profile relaxation, as well as a rapid radial transport of heat and particles. Using a mean-field helicity transport model implemented in the disruption runaway modeling framework DREAM, we calculate the dynamics of runaway electrons in the presence of current relaxation events. In scenarios where flux surfaces remain intact in parts of the plasma, a skin current is induced at the boundary of the intact magnetic field region. This skin current region becomes an important center concerning the subsequent dynamics: It may turn into a hot ohmic current channel, or a sizable radially localized runaway beam, depending on the heat transport. If the intact region is in the plasma edge, runaway generation in the counter-current direction can occur, which may develop into a sizable reverse runaway beam. Even when the current relaxation extends to the entire plasma, the final runaway current density profile can be significantly affected, as the induced electric field is reduced in the core and increased in the edge, thereby shifting the center of runaway generation towards the edge.

description: In this paper we examine link prediction for two types of data sets with mobility data, namely call data records (from the MIT Reality Mining project) and location-based social networking data (from the companies Gowalla and Brightkite). These data sets contain location information, which we incorporate in the features used for prediction. We also examine different strategies for data cleaning, in particular thresholding based on the amount of social interaction. We investigate the machine learning algorithms Decision Tree, Naïve Bayes, Support Vector Machine, and Logistic Regression.  Generally, we find that our feature selection and filtering of the data sets have a major impact on the accuracy of link prediction, both for Reality Mining and Gowalla. Experimentally, the Decision Tree and Logistic Regression classifiers performed best.

description: Cystic fibrosis transmembrane regulator (CFTR) is a dynamic membrane protein belonging to the ABC transporter family. It is unusual within this family as it is an ion channel, as opposed to a transporter. Activation of CFTR requires ATP and phosphorylation by PKA, and dysregulation of CFTR mediated salt and water homeostasis can lead to cystic fibrosis. Recent advancements in structural biological methods have led to more than 10 published CFTR structures, and, so far, all of these structures of CFTR, determined by cryo-EM, have been limited to detergent-purified protein preparations. To visualize CFTR in an environment that more closely represents its native membranous environment, we utilized two different lipoprotein particle encapsulation techniques: one in which the ion channel is first purified and then reconstituted using the membrane scaffolding protein Saposin A and another that uses the solubilizing polymer Sokalan CP9 (DIBMA) to extract CFTR directly from membranes. Structures derived from these types of preparations may better correlate to their function, for instance, the single-channel measurements from membrane vesicles.

description: We report on numerical experiment of the recurrent onset of helical "blowout" jets in an emerging flux region (EFR). We find that these jets are running with velocities of $\sim 100-250\,\mathrm{kms^{-1}}$ and they transfer a vast amount of heavy plasma into the outer solar atmosphere. During their emission, they undergo an untwisting motion as a result of reconnection between the twisted emerging and the non-twisted pre-existing magnetic field in the solar atmosphere. For the first time in the context of blowout jets, we provide a direct evidence that their untwisting motion is associated with the propagation of torsional Alfvén waves in the corona.

description: In the present paper we consider nonlinear dimers and trimers (more generally, oligomers) embedded within a linear Schr{ö}dinger lattice where the nonlinear sites are of saturable type. We examine the stationary states of such chains in the form of plane waves, and analytically compute their reflection and transmission coefficients through the nonlinear oligomer, as well as the corresponding rectification factors which clearly illustrate the asymmetry between left and right propagation in such systems. We examine not only the existence but also the dynamical stability of the plane wave states. Lastly, we generalize our numerical considerations to the more physically relevant case of Gaussian initial wavepackets and confirm that the asymmetry in the transmission properties also persists in the case of such wavepackets.

description: Corticotropin-releasing factor (CRF) regulates the stress response in the hypothalamus and modulates neurotransmission across the brain through CRF receptors. Acute stress increases hypothalamic CRF and the GABAergic neurosteroid (3α,5α)3-hydroxypregnan-20-one (3α,5α-THP). We previously showed that 3α,5α-THP regulation of CRF is sex and brain region dependent. In this study, we investigated 3α,5α-THP regulation of stress-induced hypothalamic CRF, CRF receptor type 1 (CRFR1), CRF binding protein (CRFBP), pro-opiomelanocortin (POMC), and glucocorticoid receptor (GR) by western blot and circulating corticosterone (CORT) by enzyme-linked immunosorbent assay (ELISA) in male and female Sprague Dawley rats. Tissue was collected after rats were injected with 3α,5α-THP (15 mg/kg, IP) or vehicle 15 min prior to 30 min of restraint stress (RS), or 10 min of forced swim stress (FSS) and 20 min recovery. The initial exposure to a stress stimulus increased circulating CORT levels in both males and females, but 3α,5α-THP attenuated the CORT response only in females after RS. 3α,5α-THP reduced GR levels in male and females, but differently between stressors. 3α,5α-THP decreased the CRF stress response after FSS in males and females, but after RS, only in female rats. 3α,5α-THP reduced the CRFR1, CRFBP, and POMC increases after RS and FSS in males, but in females only after FSS. Our results showed different stress responses following different types of stressors: 3α,5α-THP regulated the HPA axis at different levels, depending on sex.

description: Tobacco use is a major public health concern and is linked to myriad diseases, including cancer. The link between tobacco use and oral cancer, specifically, is very strong, making tobacco use one of the primary risk factors for oral cancer. While this association is well known, the underlying biochemical changes that result from tobacco use, and how this links to metabolic phenotypes of oral cancer, is not well understood. To address this knowledge gap, a combination of literature reviews and metabolomics studies were performed to identify commonalities in metabolic perturbations between tobacco use and oral cancers. Metabolomics analysis was performed on pooled reference urine from smokers and non-smokers, healthy and malignant oral tissues, and cultured oral cells with or without treatment of the well-known tobacco carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK). Alterations in amino acid metabolism, carbohydrates/oxidative phosphorylation, fatty acid oxidation, nucleotide metabolism, steroid metabolism, and vitamin metabolism were found to be shared between tobacco use and oral cancer. These results support the conclusion that tobacco use metabolically reprograms oral cells to support malignant transformation through these pathways. These metabolic reprogramming events may be potential targets to prevent or treat oral cancers that arise from tobacco use.

description: The advent of the second world war created a huge national demand for industrial products, munitions, and manpower. The draft removed men i from the workforce creating a gap that American women were called upon to fill. This situation was complex due to cultural ideology about women, the previous period of economic depression, and an immense need for workers. Government and industry leaders manipulated notions about gendered work in order to find a solution to the problem without creating social upheaval. In comparison to national tendencies, Pittsburgh's story is interesting because of the strict gender roles, division of labor, and industrial capabilities that characterized the city. I will explore Pittsburgh working women's experiences and media representation of them, focusing in part on how they were called into action, the ideology and propaganda forced on them, and the conditions they faced during the war effort.

description: In this paper we present a short overview on the dynamical holographic QCD method for hadron physics and QCD matter. The 5-dimensional dynamical holographic QCD model is constructed in the graviton-dilaton-scalar framework with the dilaton background field $Φ$ and the scalar field $X$ dual to the gluon condensate and the chiral condensate operator thus can represent the gluodynamics (linear confinement) and chiral dynamics (chiral symmetry breaking), respectively. The dilaton background field and the scalar field are a function of the 5th dimension, which plays the role of the energy scale, in this way, the DhQCD model can resemble the renormalization group from ultraviolet (UV) to infrared (IR). By solving the Einstein equation, the metric structure at IR is automatically deformed by the nonperturbative gluon condensation and chiral condensation in the vacuum. We review the results on the hadron spectra including the glueball spectra, the light/heavy meson spectra, as well as on QCD phase transitions, and thermodynamical as well as transport properties in the framework of the dynamical holographic QCD model.

description: We investigate a new scheme for astronomical spectrograph calibration using the laser frequency comb at the Solar Vacuum Tower Telescope on Tenerife. Our concept is based upon a single-mode fiber channel, that simultaneously feeds the spectrograph with comb light and sunlight. This yields nearly perfect spatial mode matching between the two sources. In combination with the absolute calibration provided by the frequency comb, this method enables extremely robust and accurate spectroscopic measurements. The performance of this scheme is compared to a sequence of alternating comb and sunlight, and to absorption lines from Earth's atmosphere. We also show how the method can be used for radial-velocity detection by measuring the well-explored 5-minute oscillations averaged over the full solar disk. Our method is currently restricted to solar spectroscopy, but with further evolving fiber-injection techniques it could become an option even for faint astronomical targets.

description: "If it could be said of any union that its past had shown its ability to survive even the most improbable odds, it could certainly be said of the U E ", Ronald Fiiippelli noted in his extensive study of the United Electrical, Radio and Machine Workers of America (UE), Cold War in the Working Class: The Rise and Decline of the United Electrical Workers. The United Electrical, Radio and Machine Workers of America (UE), formed in March of 1936, was to become the largest and most persistent rank-and-file union in US labor history.2 In a relatively short period of time, namely between 1936 and 1947, the UE became the third largest affiliate of the Congress of Industrial Organizations (CIO). By 1947, it had collective bargaining rights in 1,536 plants employing 600,000 workers.3 This rise of the UE did not last long, however, as the left-wing tendencies of the union leaders and the rank-and-file formation of the union made it a prime target of red-baiting occurring in the late 1940's and 1950's. Although the opposition against the UE, both from the outside and within the union, became intense in 1947, opposition to the left-wing bias of UE can be traced to as early as 1945.

description: The fact that quarks of the same electric charge possess a mass hierarchy is a big puzzle in particle physics, and it must be highly correlated with the hierarchy of quark flavor mixing. This review article is intended to provide a brief description of some important issues regarding quark masses, flavor mixing and CP violation. A comparison between the salient features of quark and lepton flavor mixing structures is also made.

description: Like most immigrants to the United States in the early part of this century, Jewish immigrants were in the majority members of the working class. They took jobs in the sweated industries of the cities where they lived, and they formed unions and other labor organizations. Many of these Jewish labor organizations had a socialist political agenda. The foremost socialist Jewish organization was the Workmen's Circle National Organization (Arbeiter Ring in Yiddish).

description: The energy budget for gravitational waves of a cosmological first order phase transitions depends on the speed of sound in the thermal plasma in both phases around the bubble wall. Working in the real-singlet augmented Standard Model, which admits a strong two-step electroweak phase transition, we compute higher order corrections to the pressure and sound speed. We compare our result to lower-order approximations to the sound speed and the energy budget and investigate the impact on the gravitational wave signal. We find that deviations in the speed of sound from $c_s^2 = 1/3$ are enhanced up to $\mathcal O(5\%)$ in our higher-order computation. This results in a suppression in the energy budget of up to $\mathcal O (50\%)$ compared to approximations assuming $c_s^2 = 1/3$. The effect is most significant for hybrid and detonation solutions. We generalise our discussion to the case of multiple inert scalars and the case of a reduced number of fermion families in order to mimic hypothetical dark sector phase transitions. In this sector with modified field content, the sound speed can receive significant suppression, with potential order-of-magnitude impact on the gravitational wave amplitude.

description: As a leading educational and research institution, Carnegie Mellon University benefits from the numerous rewards that such a position entails— an intelligent and motivated student body, a national reputation for excellence, and innovative ideas often leading to pioneering study. There is more to an institution of higher education than its academic program, though. A university campus as a community within a community is greatly affected by the trends and events of the larger community. As a university located in an urban setting, CMU suffers many problems that are directly related to the surrounding city. These include a high potential for crime, lack of adequate space for parking and facilities, and the difficult situations that arise when private institution is located on seemingly public ground. All three of these problems are encountered on a day-to-day basis by the CMU Campus Police force, whose job it is to provide the basic protective and law enforcement services required to make the campus a place of free inquiry and general security. The nature of security services at CMU and, naturally, all colleges and universities in the country, has changed drastically in the twentieth century. Law enforcement and preventive policing have taken the place of safety monitoring and reactive policing, in reaction to a number of factors that have changed the face of campus life and have forced students and administrators to reconsider the perceived safety of the campus. Among these are rising crime rates, increased student activism and unrest, and new definitions of a university's liability for the welfare of its students. To study the history of a campus security force, then, is to essentially study the campus community and the larger community in which the college or university is located.

description: The frontal lobes constitute approximately one-third of the total brain area. It is not surprising then to learn that the frontal lobes are important in a variety of functions. Research has shown us that the frontal lobes play a role in motor functions, divergent thinking, environmental control of behavior, temporal memory, spatial orientation, social behavior, olfaction, and face movements. Given this wide variety of functions, researchers have found it a difficult and puzzling task to tie them together into some sort of coherent framework that would describe an overall function of the frontal lobes. Is there any sort of 'family resemblance' among these different functions? Are these various functions related in some way? Throughout this paper I will first discuss the functions of the frontal lobes and second discuss the 'family resemblance' among these functions.

description: Dissipative coupling of resonators arising from their cooperative dampings to a common reservoir induces intriguingly new physics such as energy level attraction. In this study, we report the nonlinear properties in a dissipatively coupled cavity magnonic system. A magnetic material YIG (yttrium iron garnet) is placed at the magnetic field node of a Fabry-Perot-like microwave cavity such that the magnons and cavity photons are dissipatively coupled. Under high power excitation, a nonlinear effect is observed in the transmission spectra, showing bistable behaviors. The observed bistabilities are manifested as clockwise, counterclockwise, and butterfly-like hysteresis loops with different frequency detuning. The experimental results are well explained as a Duffing oscillator dissipatively coupled with a harmonic one and the required trigger condition for bistability could be determined quantitatively by the coupled oscillator model. Our results demonstrate that the magnon damping has been suppressed by the dissipative interaction, which thereby reduces the threshold for conventional magnon Kerr bistability. This work sheds light upon potential applications in developing low power nonlinearity devices, enhanced anharmonicity sensors and for exploring the non-Hermitian physics of cavity magnonics in the nonlinear regime.

description: This study investigated the effect of locally available bulking agents on the faecal sludge (FS) composting process and quality of the final FS compost. Dewatered FS was mixed with sawdust, coffee husk and brewery waste, and composted on a pilot scale. The evolution of physical and chemical characteristics of the composting materials was monitored weekly. Results indicate that bulking agents have a statistically significant effect (p < 0.0001) on the evolution of composting temperatures, pH, electrical conductivity, nitrogen forms, organic matter mineralisation, total organic carbon, maturity indices, quality of the final compost and composting periods during FS composting. Our results suggest reliable maturity indices for mature and stable FS compost. From the resource recovery perspective, this study suggests sawdust as a suitable bulking agent for co-composting with FS—as it significantly reduced the organic matter losses and nitrogen losses (to 2.2%), and improved the plant growth index, thus improving the agronomic values of the final compost as a soil conditioner. FS co-composting can be considered a sustainable and decentralised treatment option for FS and other organic wastes in the rural and peri-urban communities, especially, where there is a strong practice of reusing organic waste in agriculture.
