Non-linear phenomena in granular materials
Creators: name: Siu, Theodore Lordin
Publisher: name: No Publisher Supplied
Year: 2016

description: Granular materials are quite common in our everyday lives in both nature and industry. Yet much of the phenomena that they exhibit is not well understood and in fact quite complex and non-linear. For example, it has been known since Faradayâ€˜s time that swirling sandstorms are able to generate electric charge that manifest as multi-million volt lightning discharges. Poured glass beads have been demonstrated to also charge electrically, causing random ejections of grains and creating interesting raised clump structures known as razorbacks. Lastly, granular materials are known to exhibit self- segregation based on size. An example of this phenomenon is the landscape observed on the asteroid 25143/Itokawa, which has spatially separated boulder fields and sand seas.    In this work, we discuss three projects that examine non-linear behavior in granu- lar materials. In our first chapter, we discuss a computational electrostatic model of vibrated identical granular particles. We show in our model that granular materials are able to exponentially generate charge and polarization through 1/r2 electric field interactions. By adding neutralization between neighboring particles, we find complex phenomena such as charge and polarization waves that propagate through the particles. In closing, we reproduce a polarized state experimentally using vibrated glass beads which represents one of the phenomena that we observe in our model phase diagram; we also discuss our experimental efforts to image charge and polarization waves.    In the second chapter, we examine the dynamical behavior of charged granular par- ticles. We find that by experimentally exposing grains to simple electric fields, a number of novel behaviors appear including dust clouds, dust columns and tendrils. In addi- tion, in our experiments and simulations we find evidence for non-linear electrostatic interactions between particles including asymmetries and particle trajectories that do  not adhere to naive electric field lines.    In our final chapter, we deal with granular segregation found on the asteroid known  as 25143/Itokawa. On the asteroid there exists segregation between smaller sized dust and rocks on the centimeter size, from large boulders with diameters on the order of meters. While current explanations attribute the segregation to the phenomenon known as the Brazil Nut Effect, we show that "ballistic segregation"  or a difference of collision types on the asteroid surface can be responsible for the separation between different sized particles. We show that the surface area growth of particles can be modeled using the non-linear Hill Equation, which shows that increasing amounts of dust accumulation promotes further dust accumulation.

description: Even as an emerging technology, Unmanned Aerial Vehicles (UAVs) have had a tremendous impact on the world. From the way wars are fought, to the way we take selfies, drones are well on their way to revolutionizing our daily lives. One of the most innovative applications of these vehicles in the Naviator submersible-UAV. This unique multirotor is capable of aerial flight and underwater operations with seamless Air-Water transitions. In this thesis, the power system of a multirotor UAS is characterized using standard performance models with the goal of designing and optimizing the systems of a new Naviator V5 prototype. Test beds were created to collect data on BLDC motors and propellers and their performance was assessed in air and water. Theoretical models using BEM theory and the 3-constant motor model were validated for their accuracy. Experiments found that RC air propellers are similarly efficient in air and water and BLDC motor performance is partially diminished due to the higher viscosity of water. The effects of input voltage, throttle, Kv rating, and motor size were also evaluated using motor torque curves. Using this data, an optimal power system for the Naviator V5 prototype was designed, tested, and evaluated.

description: We obtain the reflected entropy for bipartite mixed state configurations involving two disjoint and adjacent subsystems in two dimensional boundary conformal field theories (BCFT$_2$s) in a black hole background. The bulk dual is described by an AdS$_3$ black string geometry truncated by a Karch-Randall brane. The entanglement wedge cross section computed for this geometry matches with the reflected entropy obtained for the BCFT$_2$ verifying the holographic duality. In this context, we also obtain the analogues of the Page curves for the reflected entropy and investigate the behaviour of the Markov gap.

GNRS assisted inter-domain services in MobilityFirst future internet architecture
Creators: name: Srinivasan, Suja
Publisher: name: No Publisher Supplied
Year: 2016

description: This thesis involves the design and evaluation of an extension to the Global Name  Resolution Service (GNRS) of the MobilityFirst Future Internet Architecture (MF-  FIA), to support inter-domain services. The GNRS is a scalable distributed system  that facilitates name-location separation in the MobilityFirst network. Currently the  GNRS stores mappings from a globally unique identi er (GUID) to network addresses  alone. The proposed extension makes the GNRS more generic by allowing it to store  GUID to mappings of di erent types. This enhanced framework enables the support  for di erent inter-domain functions.  The extension work was tested and evaluated through both simulations and ORBIT  testbed emulations. Two applications, namely multicast and late-binding in Mobility-  First, were explored as services enabled by the enhanced GNRS framework. The mul-  ticast implementation was integrated into the prototype MobilityFirst software which  is based on the open source Click routing platform and evaluated on ORBIT testbed.  Late-binding schemes were studied and evaluated through a series of real time trace  simulations. Both experiments proved the utility of the extended GNRS framework in  realizing advanced inter-domain services in the MobilityFirst network.

description: Lorentz invariance violation (LIV) is a phenomenon featuring in various quantum gravity models whereby Lorentz symmetry is broken at high energies, potentially impacting the behaviour of particles and their interactions. Here we investigate the phenomenology of LIV within the context of gamma-ray-induced electromagnetic cascades. We conduct detailed numerical simulations to explore the expected manifestations of LIV on gamma-ray fluxes, taking into account relevant effects such as pair production and inverse Compton scattering. Additionally, we consider processes forbidden in the Standard Model, namely vacuum Cherenkov emission and photon decay. Our analysis reveals that these modifications result in distinct characteristics within the measured particle fluxes at Earth, which have the potential to be observed in high-energy gamma-ray observations.

description: Phase-separated magnetic fluids provide a very strong magnetic response ($μ>25$) in a liquid state material. Even small fields can cause a notable material response, but this depends on its properties, which are often difficult to control. Here, we investigate how temperature affects the properties of the system, where phase separation is induced by an increase in ionic strength. Following the deformations of individual microscopic droplets, we can extract surface tension, magnetic permeability, and viscosity. We find that the temperature increase does not affect the surface tension, while the magnetic permeability and viscosity increase. Applying this knowledge to induce a shape instability for a drop only using temperature shows the potential of applicability of our findings.

description: Young transiting exoplanets offer a unique opportunity to characterize the atmospheres of fresh and evolving products of planet formation. We present the transmission spectrum of V1298 Tau b; a 23 Myr old warm Jovian sized planet orbiting a pre-main sequence star. We detect a primordial atmosphere with an exceptionally large atmospheric scale height and a water vapour absorption at 5$σ$ level of significance. We estimate a mass and density upper limit (24$\pm$5$M_{\oplus}$, 0.12gm/$cm^{3}$ respectively). V1298 Tau b is one of the lowest density planets discovered till date. We retrieve a low atmospheric metallicity (logZ=$-0.1^{+0.66}_{-0.72}$ solar), consistent with solar/sub-solar values. Our findings challenge the expected mass-metallicity from core-accretion theory. Our observations can be explained by in-situ formation via pebble accretion together with ongoing evolutionary mechanisms. We do not detect methane, which hints towards a hotter than expected interior from just the formation entropy of this planet. Our observations suggest that V1298 Tau b is likely to evolve into a Neptune/sub-Neptune type of planet.

description: Driophlox Scott, Chesser, Unitt, and Burns, genus nov.
Type species. Phoenicothraupis gutturalis Sclater, 1854.
Included species and subspecies. Driophlox gutturalis (Sclater, 1854) comb. nov., Driophlox atrimaxillaris (Dwight & Griscom, 1924) comb. nov., Driophlox cristatus (Lawrence, 1875) comb. nov., Driophlox fuscicauda (Cabanis, 1861) comb. nov., Driophlox fuscicauda discolor (Ridgway, 1901) comb. nov., Driophlox fuscicauda erythrolaema (Sclater, 1862) comb. nov., Driophlox fuscicauda fuscicauda (Cabanis, 1861) comb. nov., Driophlox fuscicauda insularis (Salvin, 1888) comb. nov., Driophlox fuscicauda salvini (Berlepsch, 1883) comb. nov., Driophlox fuscicauda willisi (Parkes, 1969) comb. nov.
Diagnosis. Compared to Habia rubica, species of Driophlox are typically characterized by more conspicuous red or orange throats that contrast more with the rest of the underparts, and by dark brown or dark gray upperparts, differing from the reddish-brown upperparts of Habia rubica. Molecular analyses of Barker et al. (2015) and Scott (2022) revealed differences in both mtDNA and nuclear loci. These differences showed that the species placed in this new genus are not sister to Habia rubica, which is the type species of Habia and sister to Chlorothraupis. Cladistically, we define this genus as the descendants of the common ancestor of Driophlox gutturalis and Driophlox fuscicauda.
Etymology. From the Greek δριος (drios, translated in Liddell’s Greek–English Lexicon as “copse” or “thicket,” alluding to the birds’ habitat of forest undergrowth) and φλοξ (phlox, fire or flame, alluding to the varying shades of red plumage in males, as well as to the red crown patch or crest). The name thus means “flame of the forest undergrowth.” Like other names compounded from the root - phlox, it is feminine in gender, as is Habia. Thus, adoption of Driophlox entails no need for change in any specific or subspecific epithet.

description: With the advent of JWST and spectroscopic characterization of exoplanet atmospheres with unprecedented detail, there is a demand for a more complete picture of chemical and photochemical reactions and their impact on atmospheric composition. Traditionally, building reaction networks for (exo)planetary atmospheres involves manually tracking relevant species and reactions, a time-consuming and error-prone process. This approach's applicability is also often limited to specific conditions, making it less versatile for different planetary types. (i.e., photochemical networks for Jupiters may not be directly applicable to water-rich exoplanets). We introduce an automated approach using a computer-aided chemical reaction network generator, combined with a one-dimensional photochemical kinetic-transport model, offering significant advantages. This approach automatically selects reaction rates through a rate-based iterative algorithm and refinement steps, enhancing model reliability. Also, this approach allows for the efficient simulation of diverse chemical environments, from hydrogen to water, carbon dioxide, and nitrogen-dominated atmospheres. Using WASP-39b and WASP-80b as examples, we demonstrate our approach's effectiveness. Our WASP-39b model aligns with prior studies and JWST observations, capturing photochemically produced sulfur dioxide. The WASP-80b model reveals an atmosphere influenced by deep interior thermochemistry and vertical mixing, consistent with JWST NIRCam observations. Furthermore, our model identifies a novel initial step for the N2-NH3-HCN pathway that enhances the conversion efficiency in high-temperature/pressure environments. This automated chemical network generation offers a novel, efficient, and precise framework for studying exoplanetary atmospheres, marking a significant advancement over traditional modeling techniques.

description: In this work, we establish a theoretical analysis of the emergence of layer-contrasted Nernst response perpendicular to the direction of the temperature gradient in twisted moiré layers, called layer Nernst effect (LNE). This phenomenon arises from the trigonal warping of the Fermi surface along with a layer-contrasted pseudomagnetic field. Interestingly, the Fermi surface's warping explicitly breaks intra-valley inversion symmetry, which leads to an imbalance between left- and right-moving carriers, thus resulting in a non-vanishing LNE. We then validate our theoretical scheme by applying it to twisted bilayer graphene (TBG). Importantly, we find that the LNE coefficient in TBG can reach values as high as $10^3$A/(m$\cdot$K), surpassing those of previously known materials by at least one order of magnitude. These results provide a theoretical foundation for utilizing TBG and other twisted moiré layers as promising platforms to explore layer caloritronics and develop thermoelectric devices.

Die glatten Mandibeln haben nur zerstreute ziemlich grobe Punkte. Der Clypeus, die Stirn und die Wangen sind sehr fein laengsgestreift. Die Bildung der einzelnen Koerpertheile ist so wie bei H. quadripunctata, mit welcher diese neue Art die naechste Verwandtschaft hat; der Thorax unterscheidet sich nur dadurch, dass der schneidige Rand, welcher die Basalflaeche des Metanotum von der abschuessigen Flaeche trennt, nicht, wie bei H. quadripunctata bogig ausgeschnitten, sondern gerade ist. Die Schuppe ist etwas groesser und besonders hoeher als bei der europaeischen Art, sonst aber ebenso geformt.

Comments
This species was recorded from Antalya, İstanbul, İzmir and Mersin by Önder (1976). Pagola-Carte & Rieger (2021) argued that the records of this species from Turkey most probably referred to other closely related species that occur in this region, e.g., Phytocoris carapezzai Çerçi, Koçak & Tezcan, 2019, or undescribed new species. Accordingly, our re-examination of the voucher specimens revealed that these records refer to other species. The record from İzmir refers to P. (E.) pinihalepensis Lindberg, 1948 and the records from İstanbul and Mersin refer to P. (E.) scitulus scitulus Reuter, 1908. Unfortunately, the voucher specimen belonging to the record from Antalya could not be located in LEMT. However, considering these erroneous identifications, combined with lack of genital examinations in species identification during that period, we strongly believe that the missing specimens also belonged to species other than P. scituloides. Therefore, this species is excluded from the Heteroptera checklist of Turkey.

Design and evaluation of a novel passive bioaerosol sampler
Creators: name: Therkorn, Jennifer Helen
Publisher: name: No Publisher Supplied

description: Bioaerosols are airborne particulate matter of biological origin, such as microorganisms and pollen, and any particulates shed or produced by living organisms, like pet dander and mycotoxins. A wide spectrum of adverse environmental health effects can result from exposure to these particles, such as infectious or allergic respiratory diseases. To understand and mitigate the effects of bioaerosol exposures, bioaerosol sampling must be representative of the spatiotemporal scales over which the exposures occur. However, bioaerosol sampling is typically conducted with air pumps (i.e., actively) â€“ this negatively affects the quality of the sample and limits when and where sampling can be performed.    Passive sampling, on the other hand, does not need air pumps or external power, which makes it portable, cost-effective, and practical for conducting long-term sampling in any location. My dissertation aims to design, develop and evaluate a new passive bioaerosol sampler utilizing polarized, ferroelectric polymer films to enhance electrostatic collection of biological particles while streamlining sampling to analysis procedures. Specifically, I aim to: 1) conceptually design the passive sampler using parallel layers of a polarized, ferroelectric polymer film to optimize collection of microorganism-sized particles. 2) Determine extraction efficiencies of spiked microorganisms from the surface of the polymer film. 3) Optimize a field-deployable prototype sampler design using a compact, calm air settling chamber. Finally, 4) perform outdoor field testing of the passive sampler to evaluate its performance.    Parallel layers of uniaxially oriented, polarized, poly(vinylidene fluoride), PVDF, with 2.25 mm wide air channels was found to significantly enhance electrostatic capture of particles in size ranges of interest for bioaerosol (~0.01 to 5 ï ­m) with varying particle surface charge. A spiral shaped prototype sampler with a 3D-printed film holder provided user-friendly sampler setup and 100% extraction efficiency of spiked microorganisms from the surface of the PVDF and the film holder material. Through outdoor field-testing, the new sampler passively collected microorganisms comparably to the active reference sampler with an equivalent sampling rate of ~2.6 L/min. and provided better preservation of microorganism culturability. Ultimately, this research presents a novel sampling tool for bioaerosol exposure assessment, a new methodological framework for bioaerosol sampler development, and new benchmarks of success for developing passive bioaerosol sampler technology.

Comments
This Sibero-European species has been recorded from numerous localities in Central Anatolian, Mediterranean and Black Sea regions of Turkey by Yiğit & Uygun (1982) and Lodos et al. (2003). However, after re-examination of voucher specimens, we discovered that all records of this species by Lodos et al. (2003) and Yiğit & Uygun (1982) refer to other species. Specimens from Kastamonu and Boyabat, Sinop, were females and could not be identified to species level but refer to P. (Phytocoris) sp. The female specimen from Zonguldak refers to an unidentified P. (Exophytocoris) sp. and the rest of the specimens refer to P. (Exophytocoris) scitulus scitulus.

Diese Art ist, ausser der reichlichen Behaarung im Allgemeinen, durch die dichte, sehr lange, steife und abstehende Behaarung an der Streckseite der Schienen und Tarsen, so wie durch die eigenthuemliche Punktirung des Kopfes und des Thorax ausgezeichnet. Diese Punkte sind aehnlich wie bei einem Fingerhute vertieft, aus ihrer Mitte erhebt sich ein sehr kleines schwarzes Knoetchen, in welches ein Borstenhaar eingepflanzt ist. Am Hinterleibe finden sich wohl keine solchen Punkte, aber die abstehenden Haare entspringen ebenfalls aus winzig kleinen schwarzen Knoetchen.

description: Preliminary larval diagnosis of the genus Misagria
The diagnosis is based on Misagria parana described in this paper, on F-0 Misagria divergens De Marmels, 1981, from Roraima State, Brazil (Neiss, in litt.; Neiss and Fleck, pers. obs.), and on F-0 Misagria cf. calverti from Amazonas State, Brazil (Fleck, pers. obs.). It may change after the discovery of new larvae belonging to the genus (ie M. bimacula Kimmins, 1943) or to closely related genera: (1) rather small (<20mm) and pilose larvae, covered by long and hair-like setae; (2) functional parts of eyes small and moderately projecting above dorsal part of epicranium; (3) occiput well developed, with short parallel lateral margins behind eyes; (4) incisors 1 and 2 almost completely fused on right mandible, with two and three molar teeth respectively on left and right mandible; (5) mask broad with prementum about as long as wide, and short, its posterior margin just reaching the anterior part of mesocoxae; (6) disposition of premental setae “S” shaped, and separated into three groups: (7) three long external setae well separated from each other by at least two times the diameter of setal basal insertion, one setae of medium size, and, close to the seta of medium size, several [6−10] shorter setae “U” or “V” disposed; (8) seven palpal setae, the distal one distinctly shorter than others; (9) crenulations on distal margin of palp smooth and squarish, numbering nine (rarely eight), each tooth with a small ventral indentation, and median teeth bearing generally three or four raptorial setae; (11) costal margins of wing pads parallel; (12) metatarsus and claws rather long and thin, with length of tarsus+claws slightly shorter than metatibia (ca 0.80 to 0.85 the length of tibia); (13) pro- and metatarsi with one row of trifid setae; (14) abdomen elongated, without dorsal hooks and with moderately developed lateral spines on S8 and S9 (length <middorsal length of their respective segment); (15) S3−S9 with middorsal rather diffuse but distinct clump of setae; (16) anal pyramid elongated with all elements acutely pointed, and with epiproct about 1.5 to 2 times as long as broad, paraprocts about as long as epiproct, and male cerci ca 0.4–0.6 of the epiproct (female cerci shorter). None of these characters is unique to the genus Misagria.

Design of analog front-end circuitry with drift removal and gain enhancement for a highly sensitive handheld impedance cytometer
Creators: name: Talukder, Niloy
Publisher: name: No Publisher Supplied
Year: 2016

description: We present a portable system for personalized blood cell counting consisting of a microfluidic impedance cytometer with portable analog readout feeding into an analog-to-digital converter (ADC). The novel design of the analog readout, which consists of a lock-in-amplifier followed by a high-pass filter stage for subtraction of drift and DC offset, and a post-subtraction high gain stage, enables detection of particles and cells as small as 1 m in diameter, despite using a low-end 8 bit ADC. Applications such as personalized health monitoring require robust device operation and resilience to clogging, thus it is desirable to avoid using channels comparable in size to the particles being detected, thus requiring high levels of sensitivity. Despite using low-end off-the-shelf hardware, our sensing platform was capable of detecting changes in impedance as small as 0.032%, allowing detection of 3 m diameter particles in 300 m wide channel. The consecutive upward and downward signature of recorded peaks further helps to differentiate the signal from the noise floor.  The performance of our system is comparable to that of a high-end bench-top impedance spectrometer under experimental condition. The novel analog design allowed for an instrument with a footprint of less than 80 cm2. The aim of this work was to demonstrate the potential of using microfluidic impedance spectroscopy for low-cost health monitoring. We demonstrated the utility of the platform technology towards cell counting, however our platform is broadly applicable to assaying wide panels of biomarkers including proteins, nucleic acids, and various cell types.
