description: Liquid crystal elastomers (LCEs) are materials formed by cross-linking crystal mesogens into a flexible polymer network, and they display soft behavior and undergo large, reversible strains. The mesogenic order determines material properties, causing coupling between temperature, liquid crystalline order, and deformation, which leads to temperature-based actuation. LCEs have important applications in soft robotics and medical devices, so attempts have been made to theoretically model their behavior in order to develop new use cases. One such model, developed by Lee (2021), identifies regions of liquid crystal orientation and has agreed with initial experimental data (Lee et al., 2023). This thesis aims to characterize the behavior of isotropic-genesis polydomain LCEs across various temperatures, strain rates, and crosslinking densities and further test the model by comparing the experimental data against it.

Tensile tests were run across five strain rates (10⁻¹/s, 5×10⁻²/s, 10⁻²/s, 5×10⁻³/s, 10⁻³/s), three temperatures (26◦C, 55◦C, 90◦C), and two crosslinking densities (50 mol%, 25 mol%). A custom tensile rig with a heated chamber made by Lee (2021) was modified for the purpose of this thesis to allow for digital image correlation and trials across temperatures.

These tensile tests revealed that stiffness increased with faster strain rates, and, as temperature increased, soft behavior was reduced at 55◦C and vanished at above the nematic transition temperature. Additionally, residual strain decreased with increasing temperature, at ∼1.5 at 26◦C, ∼0.75 at 55◦C, and ∼0.1 at 90◦C. Reducing the crosslinking density more than doubled the strain at failure and drastically
increased the region of soft behavior.

Experimental data across three strain rates (10⁻²/s, 5×10⁻³/s, 10⁻³/s), three temperatures, and at 50 mol% crosslinking density were compared against the model developed by Lee (2021). The soft behavior of the LCE was generally well characterized by the model, however, the model deviated from experimental data above two strain, as the Neo Hookean-based model was unable to capture strain hardening. Since higher temperature trials were run to lower strains, the model was able to better capture the full behavior of the LCE at higher temperatures, even with the loss of soft behavior at 90◦C. This model is therefore a useful tool for modeling LCE soft behavior across various temperatures.

description: We propose a new mechanism of lepton (L) number asymmetry generation, hence offer an explanation of matter-antimatter imbalance when a significant amount of baryon number is later transformed from this L-number by known electroweak sphaleron mediated process. The basic theoretical framework is a recently proposed multiple scalar-tensor gravity that dynamically solves the cosmological constant problem. The L-asymmetry generation in one of two proposed scenarios is triggered by dynamical relaxation of scalar inflaton field towards the zero cosmological constant. CPT violation (C= charge conjugation, P = parity operation, T= time reversal) in the presence of a chemical potential gives the necessary time arrow, and lepton number violating scattering in cosmic thermal medium generates a net cosmological L-number via resonance formation. Another scenario is L-asymmetry generation from evaporating primordial black holes. These proposed mechanisms do not require CP violating phases in physics beyond the standard model: the new required physics is existence of heavy Majorana leptons of masses $ 10^{15} \sim 10^{17}$ GeV that realizes the seesaw mechanism. We identify the cosmological epoch of lepto-genesis in two scenarios, which may give the right amount of observed baryon to entropy ratio. It might even be possible to experimentally determine microscopic physics parameter, masses of three heavy Majorana leptons by observing astrophysical footprints of primordial black hole evaporation at specified hole masses.

description: Inspired by the recent determination of the $W$-boson mass by the CDF collaboration, we revisit an $SO(10)$ axion model in which a scalar $SU(2)_L$ triplet field with zero hypercharge is known to acquire a non-zero VEV through its mixing with the Standard Model Higgs doublet. The triplet VEV provides a sizable contribution to the $W$ mass, which helps in significantly lowering the $7σ$ discrepancy between the Standard Model prediction and the higher CDF value for $m_W$. We show that the relatively light triplet mass ($\sim (1-50)$ TeV) is compatible with gauge coupling unification and observable proton decay. An unbroken $Z_2$ gauge symmetry, coupled with the presence of two fermionic $10$-plets required to resolve the axion domain wall problem, means that both axions and a stable intermediate mass ($\sim 10^9-10^{10}$ GeV) fermion are plausible dark matter candidates. We also display the gravitational wave spectrum from the intermediate scale topologically stable cosmic strings predicted by the model.

Orthognathic Speech Pathology: Understanding How Class III Jaw Disharmonies Influence Speech Utilizing Spectral Moment Analysis

description: Patients with severe jaw disproportions seek orthodontic care and orthognathic surgery to address issues with mastication, esthetics and speech; speech concerns surpass impaired chewing function as a motivator for surgery. Pathologic speech impedes communication, profoundly impacting quality of life. We hypothesized that deviations from normal central frequencies of consonant sounds correlate with severity of anterior-posterior and jaw disproportions. To test our hypothesis, we evaluated 31 patients with dentofacial deformity and 10 reference individuals for status of occlusal relationships and qualitative characteristics of speech patterns. Qualitative assessment was completed by a speech pathologist through direct evaluation. Audio recordings were collected on each subject and quantitatively analyzed to measure sound frequency distortions. Overall, these experiments revealed that 77% of Class III subjects produced abnormal dentalized sounds compared to 10% of controls and that a shift existed in the /t/ and /tʃ/ central tendency relative to controls. Trends correlating severity of Class III with articulation distortion were found with 3 tested phonemes: /k/, /s/ and /ʃ/. These findings provide critical insight into the complex interplay between craniofacial and vocal structures, and may elucidate how the treatment of dentofacial deformities may impact speech-sound disorders.

description: Crystallographic twins are critical to the properties of numerous materials from magnesium alloys to piezoelectrics. Since the onset of the twin formation is highly sensitive to the triaxial mechanical boundary conditions, non-destructive bulk microscopy techniques are required. Elastic strains can be mapped via X-ray diffraction with a 100-200 nm resolution. However, the interplay of strains with nanotwins cannot be characterized. Here, a method based on dark-field X-ray microscopy to quantify the density of nanotwin variants with twin lamellae of sizes as small as several tens of nanometers in embedded subvolumes (70x200x600 nm³) in millimeter-sized samples is introduced. The methodology is corroborated by correlating the local density of twin variants to the long-ranging strain fields for a high-performance piezoelectric material. The method facilitates direct, in situ mapping and quantification of nanoscale structural changes together with their elastic driving fields, which is the key towards controlling and engineering material's performance at nanometric scales.

description: During the violent relaxation of a self-gravitating system a significant fraction of its mass may be ejected. If the time varying gravitational field also breaks spherical symmetry this mass can potentially carry angular momentum. Thus starting initial configurations with zero angular momentum can in principle lead to a bound virialized system with non-zero angular momentum. We explore here, using numerical simulations, how much angular momentum can be generated in a virialized structure in this way, starting from configurations of cold particles which are very close to spherically symmetric. For initial configurations in which spherical symmetry is broken only by the Poissonian fluctuations associated with the finite particle number $N$, with $N$ in range $10^3$ to $10^5$, we find that the relaxed structures have standard "spin" parameters $λ\sim 10^{-3}$, and decreasing slowly with $N$. For slightly ellipsoidal initial conditions, in which the finite-$N$ fluctuations break the residual reflection symmetries, we observe values $λ\sim 10^{-2}$, of the same order of magnitude as those reported for elliptical galaxies. The net angular momentum vector is typically aligned close to normal to the major semi-axis of the triaxial relaxed structure, and also with that of the ejected mass. This simple mechanism may provide an alternative, or complement, to "tidal torque theory" for understanding the origin of angular momentum in astrophysical structures.

description: Axions with masses of order keV can be produced in great abundance within the Solar core. The majority of Sun-produced axions escape to infinity, but a small fraction of the flux is produced with speeds below the escape velocity. Over time, this process populates a basin of slow-moving axions trapped on bound orbits. These axions can decay to two photons, yielding an observable signature. We place the first limits on this solar basin of axions using recent quiescent solar observations made by the NuSTAR X-ray telescope. We compare three different methodologies for setting constraints, and obtain world-leading limits for axions with masses between 5 and 30 keV, in some cases improving on stellar cooling bounds by more than an order of magnitude in coupling.

description: The death of Matthew Perry, best known for his role as Chandler Bing in the television series Friends, has seen an outpouring of grief from fans and the Hollywood community. In forming relationships with fictional characters, we form bonds with the performers who bring them to life. The lines between character and creator become blurry, both because of the knowledge about actors’ lives celebrity culture affords us, but also because their characters seem so real. When the actors pass away, we feel real grief.

description: Современные механизмы управления региональным развитием у властей разных структур разнообразны. Их можно разделить на две большие группы: непосредственные или административнораспорядительные и опосредованные, к которым относятся экономические, технико-технологические, социальные и т.п. Группу непосредственных представляют административно-распорядительные механизмы, основанные на непосредственной подчиненности различных структур власти. Это так называемый принцип иерархии, конституирующий подчинение нижестоящего вышестоящему, вертикали власти и т.п. Федеральная власть как высшая в государстве осуществляет управление региональной как за счет своих структур в регионе, так и путем подотчетности региональных органов государственной власти федеральной. Механизм подчинения прописан конституцией и законами и формируется в виде распоряжений, приказов и т.д., которые признаются обязательными к исполнению нижестоящими структурами, т.е. распоряжения федеральных органов власти обязательны к исполнению региональными органами власти. Важное значение в системе управления регионом имеет механизм реализации субъектом управления своих полномочий внутри федерации. В связи с переходом на рыночные отношения и сопровождающие их становление разгосударствление и приватизацию, а также дальнейшую демократизацию управления мало внимания уделяется исследованию особенностей механизма государственного управления территориями. Характер современной модели государственного управления заключается в образовании восьми федеральных округов, ( СевероЗападный федеральный округ, Центральный федеральный округ, Приволжский федеральный округ, Южный федеральный округ, Северо-Кавказский федеральный округ, Уральский федеральный округ, Сибирский федеральный округ, Дальневосточный федеральный округ), которые покрывают территорию страны с запада на восток и с юга на север. Федеральные округа не являются аналогами «экономических районов».

description: Higher-order topological insulators have been introduced in the precursory Benalcazar-Bernevig-Hughes quadrupole model, but no electronic compound has been proposed to be a quadrupole topological insulator (QTI) yet. In this work, we predict that Ta$_2M_3$Te$_5$ ($M=$ Pd, Ni) monolayers can be 2D QTIs with second-order topology due to the double-band inversion. A time-reversal-invariant system with two mirror reflections (M$_x$ and M$_y$) can be classified by Stiefel-Whitney numbers ($w_1, w_2$) due to the combined symmetry $TC_{2z}$. Using the Wilson loop method, we compute $w_1=0$ and $w_2=1$ for Ta$_2$Ni$_3$Te$_5$, indicating a QTI with $q^{xy}=e/2$. Thus, gapped edge states and localized corner states are obtained. By analyzing atomic band representations, we demonstrate that its unconventional nature with an essential band representation at an empty site, i.e., $A_g@4e$, is due to the remarkable double-band inversion on Y-$Γ$. Then, we construct an eight-band quadrupole model with $M_x$ and $M_y$ successfully for electronic materials. These transition-metal compounds of $A_2M_{1,3}X_5$ ($A$ = Ta, Nb; $M$ = Pd, Ni; $X$ = Se, Te) family provide a good platform for realizing the QTI and exploring the interplay between topology and interactions.

description: Anisotropic transport, Shubnikov-de Haas (SdH), and de Haas-van Alphen (dHvA) quantum oscillations studies are reported on a high-quality CoSi single crystal grown by the Czochralski method. Temperature-dependent resistivities indicate the dominating electron-electron scattering. Magnetoresistance (MR) at 2 K reaches 610% for I||[111] and B||[01-1], whereas it is 500% for I||[01-1] and B||[111]. A negative slope in field-dependent Hall resistivity suggests electrons are the majority carriers. The carrier concentration extracted from Hall conductivity indicates no electron-hole compensation. In 3D CoSi, the electron transport lifetime is found to be approximately in the same order as quantum lifetime, whereas in 2D electron gas the long-range scattering drives the transport life much larger than the quantum lifetime. From linear and Hall SdH oscillations the effective masses and Dingle temperatures have been calculated. The dHvA oscillation reveals three frequencies at 18 ($γ$), 558 ($α$) and 663 T ($β$)), whereas, SdH oscillation results in only two frequencies $α$ and $β$. The $γ$ frequency observed in dHvA oscillation is a tiny hole pocket at the $Γ$ point.

description: We study the particle trajectories in the recently proposed five dimensional warped (generalized) Ellis-Bronnikov spacetime (5D-WGEB) (which does not require exotic matter) as well as it's four dimensional counterpart (4D-GEB) in detail and conduct a comparative study. Analytical approach provides conditions which determines three types of trajectories (trapped, returning and crossing) for both 4D and 5D spacetimes. Notably in 5D geometry existence of trapped trajectories become highly sensitive to the initial conditions. We have solved the timelike geodesic equations numerically and presented the trajectories graphically along with corresponding geodesic potentials. We thus distinguished the roles of the so-called wormhole parameter and the warping factor regarding their effects on the trajectories and embedding as such. Interestingly, the 5D-WGEB model shows the localization of massive particles around the location of the brane for growing warp factor and runaway trajectories for decaying warp factor.

Identification of novel intracellular mechanisms in developmental spine pruning through Ankyrin B.
Creators: name: Wyatt, Elliott
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2019

description: Dendritic spines are the predominant site of glutamatergic inputs throughout the brain. Regulation of spines is therefore critical for refining cortical networks. This research sought to define mechanisms for determining spine fate during developmental synapse remodeling. The central hypothesis is that NrCAM requires intracellular interactions within the spine to promote Semaphorin3F receptor clustering and spine retraction, through binding to the actin adaptor AnkB and microtubule binding protein DCLK1. I have delineated intracellular binding partners of NrCAM in synapse-enriched cellular fractions. I made a mutation in NrCAM that disrupts binding to AnkB and DCLK1 and perturbs Sema3F holoreceptor functioning. I demonstrated that chemical disruption of microtubules affects spine morphology and response to Sema3F. Finally, I have shown in vivo mutations affecting AnkB result in altered spine densities. The findings provide insight toward understanding the molecular mechanisms of dendritic spine remodeling and the pathology of neurodevelopmental disorders involving dendritic spine anomalies.

description: В данной работе отражена роль центров профориентации и необходимость создания профильных центров, каждый из которых будет относиться к своему отраслевому направлению и знакомить школьников с множеством профессий, входящих в это направление. Основная цель такого центра: ознакомление и подбор специальности, которая подойдёт человеку больше всего. Формирование таких центров связано с необходимостью повысить осведомленность в специфических профессиях, таких как профессии аэрокосмической области, когда у школьников зачастую нет даже базового представления об отрасли, возникает задача: как ясно преподнести информацию о специальностях аудитории школьников. Формирование площадок и подготовка координаторов по популяризации профессии на базе ВУЗов может быть уникальным решением для профориентации.

description: We present a catalog of 948,216 stars with mass label and a catalog of 163,105 red clump (RC) stars with mass and age labels simultaneously. The training dataset is cross matched from the LAMOST (The Large Sky Area Multi-Object Fiber Spectroscopic Telescope) DR5 and high resolution asteroseismology data, mass and age are predicted by random forest method or convex hull algorithm. The stellar parameters with high correlation with mass and age are extracted and the test dataset shows that the median relative error of the prediction model for the mass of large sample is 3\% and meanwhile, the mass and age of red clump stars are 4\% and 7\%. We also compare the predicted age of red clump stars with the recent works and find that the final uncertainty of the RC sample could reach 18\% for age and 9\% for mass, in the meantime, final precision of the mass for large sample with different type of stars could reach 13\% without considering systematics, all these are implying that this method could be widely used in the future. Moreover, we explore the performance of different machine learning methods for our sample, including bayesian linear regression (BYS), gradient boosting decision Tree (GBDT), multilayer perceptron (MLP), multiple linear regression (MLR), random forest (RF) and support vector regression (SVR). Finally we find that the performance of nonlinear model is generally better than that of linear model, and the GBDT and RF methods are relatively better.

description: Положительные показатели финансовых результатов коммерческой организации выступают основой ее экономического развития, способствуют укреплению взаимоотношений с различными участниками экономических процессов. Однако даже при наличии положительного финансового результата необходим грамотный подход к его анализу. Качественный анализ финансовых результатов дает реальную картину эффективности деятельности этого субъекта по всем направлениям. Изучение специальной литературы по исследуемой проблематике показало, что проведение анализа финансовых результатов происходит по определенному алгоритму. Проведение анализа финансовых результатов исследуемой организации целесообразно начать с анализа динамики двух показателей прибыли, а именно прибыли до налогообложения и чистой прибыли за отчётный период. В условиях рыночных отношений роль показателей рентабельности деятельности коммерческой организации, характеризующей уровень прибыльности ее деятельности, достаточно велика.

Automatic detection and correction of disfluencies in English spontaneous speech

description: Spontaneous speech is optimized for human-human communication, but it presents major challenges to intelligent systems interacting with people. Lack of sequential turns, presence of non-verbal cues and disfluencies (i.e., disruptions to fluent speech) are some properties of spontaneous speech that intelligent systems need to handle in order to achieve a humanlike understanding of speech. Of the challenges associated with modeling spontaneous speech, this thesis will focus on detecting and correcting speech disfluencies. I first begin by considering the challenge of learning disfluency-related features in recurrent and convolutional neural networks. Although state-of-the-art disfluency detection results have been reported for deep neural networks, their performance still heavily depends on hand-crafted features. My first contribution is a novel neural layer that rectifies the architectural limitations that prevent pre-Transformer models from learning appropriate features from words alone. Extensive evaluations indicate that the proposed model is able to automatically learn these features and its performance is competitive to complex approaches in the literature. Disfluencies are problematic for conventional syntactic parsers, which typically fail to find any disfluency nodes at all. I address this problem by investigating a multi-task learning model for joint disfluency detection and constituency parsing. I show that modern deep neural syntactic parsers, unlike conventional parsers, not only can detect disfluencies as part of parsing task but their performance is also better than specialized disfluency detection systems. I also demonstrate that syntactic information helps the neural syntactic parser detect disfluencies more accurately. Lack of large-scale labeled data is a bottleneck for improving the performance of disfluency detection models. The existing data augmentation techniques usually generate artificial synthetic disfluencies which hardly resemble gold natural data. I address the scarcity of human-labeled data by exploring a self-training technique. I show conventional methods for improving system performance (self-training and ensembling) produce a competitive or better result than all of the specialized methods for exploiting unlabelled data mentioned in the prior work. Despite these advances, disfluency detection models do not generalize well to ASR outputs. This limitation severely hinders the use of these models in real applications. To address this problem, I propose the end-to-end task of speech recognition and disfluency removal. I show end-to-end ASR models do learn to directly generate fluent transcripts out of disfluent speech. I also introduce two new metrics for evaluating the performance of end-to-end models. The findings of this research serve as a starting point for future research into end-to-end ASR and disfluency removal systems.
Consistent truncations of M-theory for general SU(2) structures

description: In seven dimensions any spin manifold admits an SU(2) structure and therefore very general M-theory compactifications have the potential to allow for a reduction to N=4 gauged supergravity. We perform this general SU(2) reduction and give the relation of SU(2) torsion classes and fluxes to gaugings in the N=4 theory. We furthermore show explicitly that this reduction is a consistent truncation of the eleven-dimensional theory, in other words classical solutions of the reduced theory also solve the eleven-dimensional equations of motion. This reduction generalizes previous M-theory reductions on Tri-Sasakian manifolds and type IIA reductions on Calabi-Yau manifolds of vanishing Euler number. Moreover, it can also be applied to compactifications on certain G2 holonomy manifolds and to more general flux backgrounds.

Verifying Catamorphism-Based Contracts using Constrained Horn Clauses

description: We address the problem of verifying that the functions of a program meet their contracts, specified by pre/postconditions. We follow an approach based on constrained Horn clauses (CHCs) by which the verification problem is reduced to the problem of checking satisfiability of a set of clauses derived from the given program and contracts. We consider programs that manipulate algebraic data types (ADTs) and a class of contracts specified by catamorphisms, that is, functions defined by simple recursion schemata on the given ADTs. We show by several examples that state-of-the-art CHC satisfiability tools are not effective at solving the satisfiability problems obtained by direct translation of the contracts into CHCs. To overcome this difficulty, we propose a transformation technique that removes the ADT terms from CHCs and derives new sets of clauses that work on basic sorts only, such as integers and booleans. Thus, when using the derived CHCs there is no need for induction rules on ADTs. We prove that the transformation is sound, that is, if the derived set of CHCs is satisfiable, then so is the original set. We also prove that the transformation always terminates for the class of contracts specified by catamorphisms. Finally, we present the experimental results obtained by an implementation of our technique when verifying many non-trivial contracts for ADT manipulating programs.

Intertemporal Substitutability, Risk Aversion and Asset Prices

description: Is the elasticity of intertemporal substitution (EIS) more or less than one? This question can be answered by confronting theoretical results of asset pricing models with investor behaviour during episodes of stock market panic. If we consider these episodes as periods of high risk aversion, then lower asset prices are in fact associated with higher risk aversion. However, according to theoretical models, risky asset price is an increasing function of the coefficient of risk aversion only if the EIS exceeds unity. It may therefore be concluded that the EIS must be more than one to reconcile theory with the observed stock price decline during periods of panic.
