description: It is known that internal energy flow in a light beam can be divided into the orbital flow, associated with the macroscopic energy redistribution within the beam, and the spin flow originating from instantaneous rotation of the field vectors inherent in circular or elliptic polarization. In contrast to the orbital one, experimental observation of the spin flow constituent seemed problematic because (i) it does not manifest itself in the visible transformation of the beam profile and (ii) it converts into the orbital flow upon tight focusing of the beam, usually employed for the energy flow detection by the mechanical action on probe particles. We propose a two-beam interference technique that permits to obtain appreciable level of the spin flow in moderately focused beams and to detect the orbital motion of probe particles within a field where the transverse energy circulation is associated exclusively with the spin flow. This result can be treated as the first demonstration of mechanical action of the spin flow of a light field.

description: In this paper we consider the design of spectrally efficient time-limited pulses for ultrawideband (UWB) systems using an overlapping pulse position modulation scheme. For this we investigate an orthogonalization method, which was developed in 1950 by Per-Olov Löwdin. Our objective is to obtain a set of N orthogonal (Löwdin) pulses, which remain time-limited and spectrally efficient for UWB systems, from a set of N equidistant translates of a time-limited optimal spectral designed UWB pulse. We derive an approximate Löwdin orthogonalization (ALO) by using circulant approximations for the Gram matrix to obtain a practical filter implementation. We show that the centered ALO and Löwdin pulses converge pointwise to the same Nyquist pulse as N tends to infinity. The set of translates of the Nyquist pulse forms an orthonormal basis or the shift-invariant space generated by the initial spectral optimal pulse. The ALO transform provides a closed-form approximation of the Löwdin transform, which can be implemented in an analog fashion without the need of analog to digital conversions. Furthermore, we investigate the interplay between the optimization and the orthogonalization procedure by using methods from the theory of shift-invariant spaces. Finally we develop a connection between our results and wavelet and frame theory.

Subjects: subject: Housing - Resident satisfaction
subject: Aged - Dwellings

description: The purpose of this project was to conduct and evaluate an interactive design process enabling semi-independent senior citizens to participate effectively in the design of housing design for the elderly. The emphasis of the project was on the process rather than the product. The conceptual design demonstrates a potential solution and provides a starting point upon which further study and analysis could be done. This document includes a definition of "interactive design," and the characteristics of the older population. Then, using methods developed by Stanley King, Christopher Alexander, and Charles Moore, a three-stage interactive design process is described: 1. Image Workshop, 2. Design of Parts Workshop, and 3. Model-Building Workshop. The needs, preferences and priorities of the client-user group are identified "first hand," and summarized into a design program reflecting client-user response. On the basis of the client-user response, two preliminary design concepts are generated. Client-user evaluation of the first concept provides guidance and direction for the development of the second concept, each presented at interim reviews. Finally, the client­users evaluated the interactive process in terms of their perceptual experiences relating to ease of involvement, organization, personal fulfillment, and clarity of presentations, measuring the success of the interactive approach. The process was then evaluated in terms of adapting process methods to seniors as the user group, and finally, recommendations for improvement are given. The appendices highlight historical developments, review sources used in process development, provide the results of participant response collected throughout the process, the design program, design drawings suggesting further refinement, and a cost analysis.

description: In a recent study of the self-adjoint extensions of the Hamiltonian of a particle confined to a finite region of space, in which we generalized the Heisenberg uncertainty relation to a finite volume, we encountered bound states localized at the wall of the cavity. In this paper, we study this situation in detail both for a free particle and for a hydrogen atom centered in a spherical cavity. For appropriate values of the self-adjoint extension parameter, the bound states lo calized at the wall resonate with the standard hydrogen bound states. We also examine the accidental symmetry generated by the Runge-Lenz vector, which is explicitly broken in a spherical cavity with general Robin boundary conditions. However, for specific radii of the confining sphere, a remnant of the accidental symmetry persists. The same is true for an electron moving on the surface of a finite circular cone, bound to its tip by a 1/r potential.

Interactions between odorants in the activity of olfactory sensory neurons, periglomerular interneurons, and between odorants and neurotoxicants in the mouse olfactory bulb
Creators: name: Matia, Allison
Publisher: name: No Publisher Supplied

description: Sensory stimuli are never encountered in isolation. Our senses are barraged by many stimuli at once, and these stimuli can interact. The olfactory system may be particularly subject to these stimulus-stimulus interactions; however, these interactions are poorly understood. Simultaneously presented odorants can produce perceptions that differ radically from the odorants individually. These interactions are typically presumed to occur at the periphery, where odorants compete for olfactory receptor binding sites. However, these interactions could potentially also occur within the circuitry of the olfactory bulb. The established odor receptor specific mixture interaction between isoamyl acetate and whiskey lactone was investigated in olfactory sensory neurons. We found that WL does not exhibit the expected selective interaction with IAA in vivo, but it did induce a mild suppression of peripheral response to various odorants. Circuit-level mixture interactions between lemon-like odors were also explored. Sublinear summation and co-inhibition of these odors was observed in GABAergic periglomerular interneurons.In addition to odorants, the peripheral olfactory system is exposed to aerosolized materials in the environment, including toxicants. Prior studies have demonstrated that exposure to aerosolized toxicants, such as those found in e-cigarette aerosol, can induce lasting olfactory loss and toxicant transportation to the brain via the olfactory nerve. In vivo optical neurophysiology showed a decrease in odorant-evoked OSN output proportional to the amount of vape exposure. This reduction decreased the absolute inter-odor representational difference but not the relative inter-odor representational difference, suggesting an impairment in odor discrimination but not odor identification. Experimental variation of nicotine concentration and exposure duration revealed pathophysiological effects of both nicotine dose and total exposure to non-nicotine- containing vape aerosols. Mass spectroscopic analysis of unmanipulated vape fluid revealed high concentrations of neurotoxic heavy metals. When the fluid was heated via the vape device’s metal heating element, concentrations of some heavy metals increased. These results demonstrate that vaping disrupts human olfactory function through multiple mechanisms of toxicity.

Data-driven techniques for human activity sensing in smart environments
Creators: name: Chowdhury, Tahiya
Publisher: name: No Publisher Supplied
Year: 2022

description: The number of Internet-of-Things (IoT) and edge devices has exploded in the last decade, providing new opportunities to sense and enable many applications to transform everyday people’s lives. Wide-scale time series data collected through such devices, coupled with advances in learning technologies, can transform how people interact with their environment. However, as we enter the era of ubiquitous computing, there is a growing need for methods that are easy to use, computationally feasible, and require minimal human supervision to sense human activities by analyzing large-scale data. The goal of this research work is to propose data-driven techniques that focus on human activity sensing at different scales. The first part of the thesis focuses on human activity sensing at building scale for smart indoor environments. Towards that end, this work emphasizes general-purpose human activity sensing using ambient sensors for context-aware computing in smart environments. A deep neural network-based technique for sensing human-environment interaction is proposed and experiments explored interpretability for different ambient sensors and their contribution to model performance to avoid data redundancy. Identifying the challenge of distribution shift in long-term activity sensing, the thesis next focuses on time series partitioning for unlabeled IoT sensor streams, which is an important step toward continuous human activity sensing. This work proposes Cadence, a generalized change point detection technique that detects change points through hypothesis testing by learning a data representation specifically with the segmentation objective. Experiments show that it is sample-efficient, unsupervised, and can robustly detect time-series events across different applications while needing only 9–93 seconds for training. The second part of the thesis focuses on human activity sensing at city scale using large-scale spatio-temporal data. A framework is introduced for sensing urban activity and policy compliance during the COVID-19 crisis using vision and language-based sensing from street view images. Understanding the challenges of street view image usage in urban sensing due to its large scale and distribution variance, a data-driven framework is proposed to evaluate the quality of information in urban scale street view images based on quality attributes capturing spatial, temporal, and content information present in the data. Our experiments show that such framework can be useful for ranking, querying, and improving spatio-temporal data quality and usage in urban computing and activity sensing. We believe such techniques can be useful to model our living patterns by analyzing large-scale data and improve the quality of our life through applications such as home automation, energy optimization, and personalized healthcare.
A parametric study on impactor design for liquid particle collection

description: The onset of the COVID-19 pandemic has left an everlasting impact on our society. As a result of COVID-19 and the potential for future epidemics, there is a growing need and interest in developing alternative rapid testing methods. One of the most common rapid tests are nasal swabs, which are often uncomfortable and relatively invasive. If the same level of positive-result certainty can be achieved with a less invasive method, then further investigation is warranted. This thesis investigates particle impactor technology with applications to a viral "breathalyzer" that can detect viral particles such as SARS-CoV-2. A person blows into a device that captures their exhaled breath containing aerosols that serve as carriers for viral particles. The device accelerates the flow down a converging nozzle, causing a capture event onto a sensor for detection. Optimizing the design stems from theoretical and numerical results. Many researchers have contributed to improving the design of impactors; we aim to use these theoretical and experimental studies as a backbone for our initial designs. We will focus on the collection of experimental data to verify these theoretical results. A test matrix was developed and three variables were considered, including the outlet diameter W, nozzle to plate distance S, and collection orifice diameter Dₒ. Pressure was maintained as a constant, keeping consistent with human exhalation. The value of W assumed three values, S/W assumed two values, and Dₒ/W assumed four values. This led to a total of 24 unique assemblies on which to conduct tests. There was no significant trend for varying Dₒ, however there was a noticeable increase in a "clogging" effect taking place for higher orifice ratios. After conducting a series of tests, the optimal configuration was found to be W = 0.64mm, S/W = 0.5, and Dₒ/W = 1.16, resulting in a capture efficiency of approximately 60%.
Inkjet printing based method for manufacturing and dimensional control of liquid bridges for air purifier

Publisher: name: No Publisher Supplied

description: Airborne particles can be harmful to the human body if inhaled. The idea of a new type of filter that could use liquid to filter particles from the air was proposed. In order to test this idea, the filter consisting of multiple liquid bridges needs to be manufactured, and the size of the liquid bridges and the spacing between the bridges need to be accurately controlled to study the filtration efficiency of the filter. An inkjet printer was used to produce liquid drops to form such liquid bridges. The liquid used to form liquid bridges is PEG 600. To increase the contact angle between PEG 600 and the glass slides, silane surface modification was used to perform the surface treatment to the glass slides, making the contact angle between PEG 600 and the glass slides to around 70°. A model was prepared to calculate the diameter of the liquid. By using this model, a set of liquid drops were printed to test the printing performance. After testing, the model predicted the size of the liquid bridge well, and good performance of the printer allowed the printed liquid bridge to be used in the study of the purification efficiency of the purifier.

description: We construct an M-theory background dual to the metastable state recently discussed by Klebanov and Pufu, which corresponds to placing a stack of anti-M2 branes at the tip of a warped Stenzel space. With this purpose we analytically solve for the linearized non-supersymmetric deformations around the warped Stenzel space, preserving the SO(5) symmetries of the supersymmetric background, and which interpolate between the IR and UV region. We identify the supergravity solution which corresponds to a stack of $\bar{N}$ backreacting anti-M2 branes by fixing all the 12 integration constants in terms of $\bar{N}$. While in the UV this solution has the desired features to describe the conjectured metastable state of the dual (2+1)-dimensional theory, in the IR it suffers from a singularity in the four-form flux, which we describe in some details.

Structure design and device fabrication: novel copper iodide based organic-inorganic hybrids for optoelectronic applications
Creators: name: Zhu, Kun
Publisher: name: No Publisher Supplied
Year: 2022

description: Structure and properties of crystalline organic-inorganic hybrid semiconductors have been explored and studied over the past decades. As the global energy consumption has escalated dramatically, their potential applications in energy related optoelectronics are attracting more research interests. For both energy saving devices such as light emitting diodes (LEDs) and higher efficiency sustainable energy source such as solar cells (SCs), hybrid semiconductors have shown remarkable performance as the active materials. Among various types of crystalline organic-inorganic hybrids, copper(I) halide-based hybrid semiconductors have been intensively and continuously synthesized and studied, due to their abundance in structure and promising photophysical/photochemical properties. This class of materials has already demonstrated their superior performance as eco-friendly and cost-effective rare-earth elements free (REE) phosphors. Various other applications including sensing, photochromic as well as dopants for organic light emitting diodes (OLEDs) have also attracted significant research interests. My research has been focusing on designing new CuI(L) (L: organic ligands) hybrid semiconductors with desired optical and electrical properties, and fabricating them into optoelectronic devices, particularly LEDs.While CuI(L) hybrids constructed through Cu-N/P/S coordination bonds are well-known for their excellent optical properties and high photoluminescence efficiency, the low solution processibility, insufficient stability and poor charge transport properties of the 0D-cluster based CuI(L) hybrids are the main drawbacks. To satisfy the requirements as stable and highly efficient emitting layer (EML) materials for LEDs, I designed and synthesized several new classes of CuI(L) hybrids with both ionic and coordinate bonds using uniquely designed cationic ligands with free N-binding sites. Such CuI(L) hybrids not only maintain extraordinarily high internal quantum yields (IQYs) but also have high photo/thermal stability, high solubility in selected solvents and enhanced charge transport properties as a result of introducing higher dimensional structures and multiple bonding modes. For the first time, high quality solution processed thin films of crystalline CuI(L) hybrids are deposited as host material free EML. I have successfully fabricated prototype yellow and blue LED devices with these CuI(L) compounds as EML, which demonstrate decent performances and stabilities.I have also worked with a series of new copper iodide based hybrid compounds having tunable and narrow bandgaps. High quality single crystals of these materials were grown, fabricated into single crystal devices and used in charge transport property measurements. They exhibit improved conductivity, several orders of magnitude higher than lead-based perovskites. Coupled with their high stability, these materials might be a promising candidate for potential photovoltaic applications.
Unhappy pursuits: gender, duty, and independence in eighteenth-century Britain
Creators: name: Blakely, Kathryn
Publisher: name: No Publisher Supplied
Year: 2022

description: This dissertation argues that key eighteenth-century women writers privileged female-centered networks of obligation over dutiful submission to patriarchal figures. I locate these networks of obligation in eighteenth-century novels that have been otherwise ignored or cited as examples of women’s subordination. Duty is still at the heart of the eighteenth-century novel, I suggest, just not always in the ways that we have imagined. This redefinition of duty allowed authors to imagine their heroines as ethical subjects: by focusing on what women have always owed one another rather than what they owe men, duty is reestablished as an end-unto-itself rather than a stepping-stone to the “happy ending” of marriage or heavenly reward. I therefore suggest that women writers defer, redistribute, or ironize moments of narrative closure to establish new novelistic temporalities that see “the end” as largely beside the point. While the history of the novel traditionally underscores the emergence of the individualized, rights-bearing subject, I draw on affect and queer theory in addition to narratology to identify an alternative history that centers communities of obligation wherein women can access community-centered ethical subjectivity. The first half of my dissertation is devoted to texts that challenge the conventional relationship between duty and reward, both thematically, by embracing personal unhappiness as the cost of living an ethical life, and formally, by deferring narrative closure and withholding a conventional happy ending. In Chapter 1, I argue that Frances Sheridan’s The Memoirs of Miss Sidney Bidulph (1761), a sentimental novel in which the heroine renounces her unfaithful lover at her mother’s behest, models a cross-generational network of obligation that offers purpose (if not happiness) for women. My second chapter turns to Sarah Scott’s feminist utopia, Millenium Hall (1762). Like Sheridan’s Sidney Bidulph, the heroines of Scott’s novel develop a system of female obligation that sees duty as its own reward rather than a stepping-stone to future happiness. In the case of Millenium Hall, the call of feminine duty exceeds filial/maternal bonds to become a large-scale, shared charitable project that further widens the notion of who women owe and why. My third and fourth chapters turn to writers and heroines of the later eighteenth century. Chapter 3 argues that Mary Hays and Mary Wollstonecraft objectify and politicize their heroines’ unhappy feelings and histories to convert affect into a political tool. In Chapter 4, I argue that Jane Austen’s Sense and Sensibility challenges Adam Smith’s model of triangulated sympathy by introducing a new ethics wherein women can care for one another and themselves by both offering and rejecting sympathy freely.

description: We perform first principles calculations of the magnetocrystalline anisotropy energy in the five L10 FePt samples studied experimentally by Ding et al. [J. App. Phys. 97, 10H303 (2005)]. The effect of temperature-induced spin fluctuations is estimated by scaling the MAE down according to previous Langevin dynamics simulations. Including chemical disorder as given in experiment, the experimental correlation between MAE and lattice mismatch is qualitatively well reproduced. Moreover we determine the chemical order parameters that reproduce exactly the experimental MAE of each sample. We conclude that the MAE is determined by the chemical disorder rather than by lattice distortion.

Microglia and key pro-inflammatory cytokines mount weakened responses to immune challenge following abstinence from chronic fentanyl self-administration

description: Significant evidence indicates immunomodulatory effects of opioids, but there is an absence of research on how neuroinflammatory events involving microglial activation are affected by chronic fentanyl self-administration (SA) or persist after cessation of drug. To test this, a rat model of voluntary chronic, long-access fentanyl SA was used to examine the pro-inflammatory cytokine and microglial response to chronic fentanyl abuse after abstinence from drug. Male Sprague-Dawley rats self-administered fentanyl (Fent/SA) for 30 consecutive days before being randomly assigned an abstinence period of either 1 week (N=8) or 1 month (N=6). Control animals (Sal/SA) similarly received access to SA saline and subsequent abstinence periods (N=12). On the last day of abstinence, all animals received an injection of an inflammatory stimulus (lipopolysaccharide; 1.5 mg/kg, i.p.), followed by perfusion and collection of spleen and brain. Sandwich enzyme-linked immunosorbent assays (ELISAs) were conducted to analyze concentrations of IL-1β and IL-6, and all brains underwent immunohistochemistry for the microglial marker Iba1 to quantify microglial cell numbers and analyze morphological states. Soma area, soma circularity, and number of branches were measured and combined to generate an individual activation score of microglial cells. We observed suppression of LPS-induced IL-6 in Fent/SA animals at 1 week of abstinence compared to Sal/SA animals, that recovered after 1 month of abstinence; no change was observed in IL-1β concentrations. Additionally, at 1 week of abstinence Fent/SA animals exhibited greater microglial density, but decreased LPS-induced activation, compared to Sal/SA; after 1 month of abstinence, decreased activation persisted but microglial density had decreased to be less than Sal/SA animals. These data indicate that chronic fentanyl use generates lasting suppression of microglial activity, showing for the first time that the neuromodulatory effects of fentanyl persist after extended abstinence from drug.

description: Advanced glycation end products (AGEs) are the bio-marker of aging and promote the development or worsening of many degenerative diseases. AGEs are a natural consequence of our metabolism; however dietary AGEs have become of interest due to their high concentration in the heavily processed foods of the western diet. Methylglyoxal (MGO) is known to be a key intermediate to the formation of AGEs both in vitro and in vivo. In the study presented, four freeze dried berry powders (blackberry, cranberry, blueberry, and black currant) showed the ability to reduce the concentration of MGO under simulated physiological conditions. Head-Space Solid Phase Microextraction was used to retrieve modified MGO derivatives from solution to be quantified through Gas Chromatography-Mass Spectrometry (GC/MS). The blueberry powder showed the largest MGO reduction after 1 hour of incubation at 37°C with 61.66%. Black currant followed with 51.3% reduction while cranberry and blackberry were on the lower end at 43.7 and 31.4% respectively. The MGO reduction rate was also observed through a kinetic study under the same conditions. The blueberry powder exhibited the quickest reduction rate by trapping 50% of the MGO present within 5 minutes. The remaining powders showed a steady increase in MGO reduction as incubation time increased with black currant being the higher of the three, followed by cranberry and finally blackberry. In summation, the polyphenols present in commercial berry powders efficiently trap MGO and can reduce the production of AGEs, ultimately having a positive impact on human health.

description: We present the main features of the electronic structure of the heavy atoms that is best of all seen in photoionization. We acknowledge how important was and still is investigation of the interaction between low- and high frequency lasers with big intensity. We discuss the fullerenes and endohedrals as big atoms concentrating upon their most prominent features revealed in photoionization. Namely, we discuss reflection of photoelectron wave by the static potential that mimics the fullerenes electron shell and modification of the incoming photon beam under the action of the polarizable fullerenes shell. Both effects are clearly reflected in the photoionization cross-section. We discuss the possible features of interaction between laser field of both low and high frequency and high intensity upon fullerenes and endohedrals. We envisage prominent effects of multi-electron ionization and photon emission, including high energy photons. We emphasize the important role that can be played by electron exchange in these processes.

description: We report on the structural properties of epitaxial FeO layers grown by molecular beam epitaxy on MgO(111). The successful stabilization of polar FeO films as thick as 16 monolayers (ML), obtained by deposition and subsequent oxidation of single Fe layers, is presented. FeO/MgO(111) thin films were chemically and structurally characterized using low-energy electron diffraction, Auger electron spectroscopy and conversion electron Mossbauer spectroscopy (CEMS). Detailed in situ CEMS measurements as a function of the film thickness demonstrated a size-effect-induced evolution of the hyperfine parameters, with the thickest film exhibiting the bulk-wustite hyperfine pattern. Ex situ CEMS investigation confirmed the magnetic ordering of the wustite thin film phase at liquid nitrogen temperature.

antitumor activity

description: Endophytic fungi have been recognized as possible useful sources of bioactive metabolites. However, exopolysaccharide (EPS) production from endophytic fungi and its antitumor activity have been less explored. In the present study, endophtic fungus Bionectria ochroleuca M21 was exploited for the production of EPS in submerged culture. Among tested medium components, glucose, yeast extract, MgSO4 and Tween80 were found to be effective and significant on EPS production. Response surface methodology (RSM) was employed to optimize medium composition. The results showed that the significant factors were glucose, yeast extract and Tween80. The optimal medium was observed at the composition of glucose 55.7 g/L, yeast extract 6.04 g/L, MgSO4 0.25g/L and Tween80 0.1 % (v/v). Using the optimized medium, EPS production was achieve at 2.65 ± 0.16 g/L after 4 days fermentation in a 5L bioreactor. Examination of cytotoxicity showed that the EPS from B. ochroleuca M21 did not have cytotoxic activity on human liver HL-7702 cells at concentration 0.025-1.6 mg/mL. In contrast, the EPS exhibited antiproliferative activities against cell lines of liver cancer (HepG2), gastric cancer (SGC-7901) and colon cancer (HT29) in a dose- and time-dependent manner in the concentration ranges of 0.1-0.45 mg/mL.

description: We apply a range of density-functional-theory-based methods capable of describing van der Waals interactions to weakly bonded layered solids in order to investigate their accuracy for extended systems. The methods under investigation are the local density approximation, semi-empirical force fields, non-local van der Waals density functionals and the random-phase approximation. We investigate the equilibrium geometries, elastic constants and the binding energies of a large and diverse set of compounds and arrive at conclusions about the reliability of the different methods. The study also points to some directions of further development for the non-local van der Waals density functionals.

description: We investigate the effects of Na adsorption on the electronic structure of bare and Ir cluster superlattice covered epitaxial graphene on Ir(111) using angle-resolved photoemission spectroscopy and scanning tunneling microscopy. At Na saturation coverage a massive charge migration from sodium atoms to graphene raises the graphene Fermi level by about 1.4 eV relative to its neutrality point. We find that Na is adsorbed on top of the graphene layer and when coadsorbed onto an Ir cluster superlattice it results in the opening of a large bandgap of Δ = 740 meV comparable to the one of Ge and with preserved high group velocity of the charge carriers.

description: We discuss a novel concept of a polarized nuclear target for accelerator fixed-target scattering experiments, which is based on parahydrogen induced polarization (PHIP). One may be able to reach a 33% free-proton polarization in the ethane molecule. The potential advantages of such a target include operation at zero magnetic field, fast ($\sim$100 Hz) polarization reversal, and operation with large intensity of an electron beam.

description: The high price and poor quality of chicken feed these days is a problem for poultry farmers in developing countries. Insects are one possible source of protein for chicken feed. There is no direct competition between people and insects for poultry feed.in order to eat something. Examining current studies on Black Soldier Fly (BSF) larvae meal as a substitute protein source for poultry feed is the aim of this study. The harmless black soldier fly is employed as a substitute protein source for animal feed and in the extraction of organic wastes, byproducts, and side streams. The results of several studies showed that BSF larvae meal could be safely and practically used as a protein concentrate in chicken feed. BSF larvae have high concentrations of calcium and phosphorus, as well as 35–42% crude protein with biological value and an amino acid profile resembling soybean meal (SBM). BSF larvae have comparable levels of lysine and methionine to those seen in meat diet. According to recent statistics, the nutritional value of BSF larvae is comparable to that of fish meals. Several authors proposed the theory that BSF larvae meal might improve the nutritional content of SBM or replace fish meal in grill diets without impairing the production line's ability to operate. When BSF larvae were fed to layers, their laying productivity and egg quality increased. The existing body of research generally supports the feasibility of substituting BSF larvae meal for fish meal and SBM either fully or partially. Reports state that growing chicks fed BSF larvae feed had no negative effects. Based on the performance of growing and laying birds, most of the research we reviewed indicated that the nutritional value of the growth of chicks given BSF larvae diet was either superior to or equal to that of SBM. Thus, the economy and ecology benefit from the addition of BSF larvae meal to the chicken feeding system.
Streaming time: mediation as a way of life

description: Examining genres of video streaming, this dissertation asks how does streaming constitute a sensory-affective regime? In other words, how does streaming form a logic or way of making sense of the world through a specific arrangement of time, sensation, and affect? “Streaming Time: Mediation as a Way of Life” contends with streaming as a form of sensory training by considering the production and consumption of streamed video at the level of commercially produced series on streaming services, videos of police violence such as Diamond Reynolds livestream in the wake of the fatal police shooting of Philando Castile, and the use of livestreaming for political protest, such as livestreaming from protests following George Floyd’s killing by Derek Chauvin in 2020. In doing so, this dissertation frames how streaming facilitates mediation as a way of everyday life and the ideological and political implications of this. More specifically, this dissertation looks to the aesthetic and temporal formations of streaming video to define streaming as a sensory-affective regime.The key contribution of my research is a theory of streaming time. I develop this concept over the course of the dissertation by examining how different genres of streaming video form a sensory-affective regime. Streaming time encompasses a relationship between user and media that is shaped by the temporal, material, and sensorial conditions of digital life. This embodied and sensorial connection between user and media produces forms of subjecthood that have implications for understanding political action, the politics of engaging with media objects, and labor. Further, this project has significant implications for interdisciplinary scholarship thinking about the relationship between new media, users, and power. Developing a snapshot of digital life in the present, “streaming time” accounts for the significance of one of the most commonly used, yet incompletely theorized, internet technologies of the present day. I examine how the temporality of streaming constructs a connection to state politics that is ever-present and appears impossible to impede. In doing so, I offer a theory of streaming that accounts for the material and affective impact of digital culture on everyday life, and how the embodied experience of streaming informs relations to power and resistance, disappearing relations between labor and leisure, and as such is a critical part of life under neoliberalism today.

description: We report on the enhancement of antiferromagnetic coupling in epitaxial Fe/Si/Fe structures by voltage-driven spin-polarized tunneling currents. Using the ballistic electron magnetic microscopy we established that the hot-electron collector current reflects magnetization alignment and the magnetocurrent exceeds 200% at room temperature. The saturation magnetic field for collector current corresponding to parallel alignment of magnetizations rises up with the tunneling current, thus demonstrating stabilization of the antiparallel alignment and increasing antiferromagnetic coupling. We connect the enhancement of antiferromagnetic coupling with local dynamic spin torques mediated by tunneling electrons

description: The result listing from search engines includes a link and a snippet from the web page for each result item. The snippet in the result listing plays a vital role in assisting the user to click on it. This paper proposes a novel approach to construct the snippets based on a semantic evaluation of the segments in the page. The target segment(s) is/are identified by applying a model to evaluate segments present in the page and selecting the segments with top scores. The proposed model makes the user judgment to click on a result item easier since the snippet is constructed semantically after a critical evaluation based on multiple factors. A prototype implementation of the proposed model confirms the empirical validation.

description: The possibility of designing nanoelectromechanical systems (NEMS) based on relative motion or vibrations of graphene layers is analyzed. Ab initio and empirical calculations of the potential relief of interlayer interaction energy in bilayer graphene are performed. A new potential based on the density functional theory calculations with the dispersion correction is developed to reliably reproduce the potential relief of interlayer interaction energy in bilayer graphene. Telescopic oscillations and small relative vibrations of graphene layers are investigated using molecular dynamics simulations. It is shown that these vibrations are characterized with small Q-factor values. The perspectives of nanoelectromechanical systems based on relative motion or vibrations of graphene layers are discussed.
