description: Гидролокатор бокового обзора является важнейшим инструментом в арсенале исследователя подводных объектов исторического наследия. Высокая детализация гидроакустических снимков позволяют выявлять объекты и производить их первичных осмотр; однако недостаток многих систем, представленных на сегодняшнем рынке, является отсутствие программного обеспечения, позволяющего производить картирование объектов и изучаемых акваторий. В настоящей работе представлена методика получения изображений в формате GeoTiff по данным табличного формата файла CSV на примере сонограммы популярного гидролокатора бокового обзора «Starfish»
description: Sidescan sonar (SSS) has firmly established itself in the arsenal of the underwater archaeologist. Capable of obtaining high-resolution imagery, this technology allows both the recognition of submarine anthropogenic objects and their primary investigation. One of the major drawbacks of many inexpensive models available on the market is the absence of sophisticated software capable of automatic mapping and object recognition. In this paper, we discuss a proposed technique for converting comma-separated values (CSV) files into GeoTiff for Tritech Starfish SSS sonograms.
Hauntings, Palimpsests, and Aesthetics: Portraits of Remembering Schools that were Closed
Creators: name: Ulrich Papczun, Kristy Lynn
Publisher: name: University of Illinois at Chicago
Year: 2024

description: Hans Christian Andersen Public School and Friedrich Von Schiller Public School were neighborhood public elementary schools in Chicago that served low-income families of color and were closed. Both buildings are in contested neighborhoods that have been gentrifying and had non-neighborhood schools take over the spaces. This study is a deep dive into the histories, contexts, and memories of Andersen and Schiller using portraiture as methodology. I employed archival methods and visual arts-based methods to collect and analyze data about the schools, creating palimpsest portraits. Through conversations with people connected to the schools and collective remembering, I created portraits of remembering— written narrative portraits to work toward an aim of historicizing the school sites.

I draw from urban planning, sociology, philosophy, psychology, the literary world and the large amount of research already conducted on urban school closures and the connections between neighborhoods and schools. The concepts of hauntings and palimpsests weave throughout this project. I discuss the theoretical and analytical work that is done by participants through remembering the schools and argue that the stories of school closure are also stories of gentrification, public housing, and urban planning. I call on my readers to get haunted through an aesthetic awareness.

Through reflecting and remembering, the portraits resist urban school closure and point to the lasting human-level impact of school closure. With this work, I aim to disrupt the dominant narrative of school closure that is district-driven, historically and geospatially disconnected, and justified through commonsenseness. These acts of remembering invite us to reimagine solutions to the persistent inequities manifested in urban schools.

description: Motivated by the study of ribbon knots we explore symmetric unions, a beautiful construction introduced by Kinoshita and Terasaka 50 years ago. It is easy to see that every symmetric union represents a ribbon knot, but the converse is still an open problem. Besides existence it is natural to consider the question of uniqueness. In order to attack this question we extend the usual Reidemeister moves to a family of moves respecting the symmetry, and consider the symmetric equivalence thus generated. This notion being in place, we discuss several situations in which a knot can have essentially distinct symmetric union representations. We exhibit an infinite family of ribbon two-bridge knots each of which allows two different symmetric union representations.

Основной археологический материал с мелководного участка в центральной части бухты представлен крупными фрагментами амфор VIII–IX вв., кровельной черепицей римского (I–III вв.) и средневекового времени (IX–X вв.), фрагментом импортной клейменой амфоры вт. пол.VI – нач. VII вв., многочисленными фрагментами оконного стекла и стеклянных рюмок вт. пол. V-VII вв. Находки стекла позволяют предполагать существование на «островке» сооружения общественного или религиозного назначения. На южной стороне отмели с помощью БПЛА выявлена каменная насыпь протяженностью около 60 м и шириной 20 м. Этот объект, возможно функционально связанный с использованием акватории бухты в качестве гавани, требует дальнейшего изучения
description: Underwater exploration in The Kruglaya Bay, in the area of the rocky shoal, was carried out by the expedition of The Department of Underwater Archeology of The State Museum-Preserve «Tauric Chersonese» during two seasons. The main archaeological material from the shallow-water area in the central part of the bay is represented by plenty of amphorae’s fragments (8th – 9th centuries), roof tiles from the Roman (1st – 3rd centuries) and medieval times (9th – 10th centuries), a fragment of an imported stamped amphora from the second half of the 6th – early 7th centuries, numerous fragments of window glass and glasses of the 5th – 7th centuries. Glass findings suggest the existence of a public or religious building on the «island». On the southern side of the shallow, a UAV revealed a stone embankment about 60 m long and 20 m wide. This object, possibly functionally connected with the use of the bay water area as a harbor, requires further study
Hamiltonian and Brownian systems with long-range interactions: IV. General kinetic equations from the quasilinear theory

Publisher: name: arXiv
Year: 2007
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We develop the kinetic theory of Hamiltonian systems with weak long-range interactions. Starting from the Klimontovich equation and using a quasilinear theory, we obtain a general kinetic equation that can be applied to spatially inhomogeneous systems and that takes into account memory effects. This equation is valid at order 1/N in a proper thermodynamic limit and it coincides with the kinetic equation obtained from the BBGKY hierarchy. For N tending to infinity, it reduces to the Vlasov equation describing collisionless systems. We describe the process of phase mixing and violent relaxation leading to the formation of a quasi stationary state (QSS) on the coarse-grained scale. We interprete the physical nature of the QSS in relation to Lynden-Bell's statistical theory and discuss the problem of incomplete relaxation. In the second part of the paper, we consider the relaxation of a test particle in a thermal bath. We derive a Fokker-Planck equation by directly calculating the diffusion tensor and the friction force from the Klimontovich equation. We give general expressions of these quantities that are valid for possibly spatially inhomogeneous systems with long correlation time. We show that the diffusion and friction terms have a very similar structure given by a sort of generalized Kubo formula. We also obtain non-markovian kinetic equations that can be relevant when the auto-correlation function of the force decreases slowly with time. An interest of our approach is to develop a formalism that remains in physical space (instead of Fourier space) and that can deal with spatially inhomogeneous systems.

description: Abstract: The Philippines has consistently ranked low in science in the Program for International Student Assessment (PISA). In the PISA 2022 results, only 23% of Filipino students achieved basic proficiency in science, highlighting significant challenges in the science education system. Moreover, the results of the Regional Diagnostic Assessment for Grades 7 and 8 learners at John J. Russell Memorial High School identified the least learned competencies in physics topics. This prompted researchers to develop a strategy called Image-Based Mnemonics (IBM), aimed at enhancing learners' vocabulary in physics to help them comprehend difficult terms and complex concepts more easily. The study employed a multiphase mixed-method design. Two heterogeneous sections from Grade 7 were selected as respondents through purposive sampling techniques. A validated, researcher-made image-based mnemonic was used as a strategy for teaching physics. Before each lesson, the corresponding Image-Based Mnemonics (IBM) were displayed on the board to engage students. During discussions, the images were analyzed and interpreted to aid comprehension. The experimental group used IBM four times a week, covering three major physics topics in the third quarter. The mean score in the post-test of the experimental group was higher (M = 21.522, SD = 2.83) than that of the control group (M = 14.560, SD = 2.28). The computed absolute t-values in the results of the comparative-based questions (t = -32.000, t = -13.525), which were both significantly higher than the t-critical, and the p-values, both at p = 0.000, indicate that the experimental group demonstrated significant improvement upon exposure to IBM. These suggest that the use of image-based mnemonics has a highly promising impact on enhancing learners’ vocabulary skills in physics. Additionally, the learners' responses to the interview guide revealed high satisfaction and enjoyment in the learning process upon exposure to IBM. These findings were further supported by their perceptions, concluding that the integration of image-based mnemonics in science classes was beneficial, enjoyable, and motivating for learners.

Сенот находится в Мексике, на восточном побережье полуострова Юкатан – примерно в 4 км севернее Тулума. Внутри сенота вырезано большое количество петроглифов – они образуют так называемую «лестницу с петроглифами», кроме того, в противоположной от входа части сенота установлена стела, на которую также нанесены петроглифы. Наличие большого количества петроглифов, стелы, алтаря и подношений свидетельствует об исключительной значимости сенота Танках в качестве сакрального пространства в культуре древних майя. Сенот является частью системы подводных пещер, которые соединяют сенот Танках с морем и пещерной системой Сак-Актун.
description: The article contains some results of the expedition, during which the Tancah Cenote was explored. This cenote is located in Mexico, on the east coast of the Yucatan Peninsula on the territory of the archaeological site Tancah, about 4 km north from Tulum. Inside the cenote there is a large number of petroglyphs which form the so-called “petroglyphic stairway”, moreover, in another part of the cenote there is a stela with petroglyphs. The presence of a large number of petroglyphs, stela, altar and offerings reveals the significance of the Tancah Cenote as a sacred space in the culture of the ancient Maya. The cenote is a part of a huge underwater cave system which connects the Tancah Cenote with the Carribean Sea and Sistema Sac Actun. Preliminary underwater research revealed fragments of pottery and bones at the bottom of the cenote.

description: The quest for nonmagnetic Weyl semimetals with high tunability of phase has remained a demanding challenge. As the symmetry breaking control parameter, the ferroelectric order can be steered to turn on/off the Weyl semimetals phase, adjust the band structures around the Fermi level, and enlarge/shrink the momentum separation of Weyl nodes which generate the Berry curvature as the emergent magnetic field. Here, we report the realization of a ferroelectric nonmagnetic Weyl semimetal based on indium doped Pb1 xSnxTe alloy where the underlying inversion symmetry as well as mirror symmetry is broken with the strength of ferroelectricity adjustable via tuning indium doping level and Sn/Pb ratio. The transverse thermoelectric effect, i.e., Nernst effect both for out of plane and in plane magnetic field geometry, is exploited as a Berry curvature sensitive experimental probe to manifest the generation of Berry curvature via the redistribution of Weyl nodes under magnetic fields. The results demonstrate a clean non-magnetic Weyl semimetal coupled with highly tunable ferroelectric order, providing an ideal platform for manipulating the Weyl fermions in nonmagnetic system.

description: Following our recent work on the cosmological constant problem, in this letter we make a specific proposal regarding the fine structure (i.e., the spectrum) of dark energy. The proposal is motivated by a deep analogy between the blackbody radiation problem, which led to the development of quantum theory, and the cosmological constant problem, which we have recently argued calls for a conceptual extension of the quantum theory. We argue that the fine structure of dark energy is governed by a Wien distribution, indicating its dual quantum and classical nature. We discuss a few observational consequences of such a picture of dark energy.

description: Globally, the prevalence of prehypertension and hypertension among adults in low- and middle-income countries is on the rise. However, the data on young people remains scarce. In this context, we analyzed data from two national-level cross-sectional surveys— NFHS–4, which included 272,966 individuals, and NFHS–5, which included 250,213 individuals—to assess changes in the prevalence of prehypertension and hypertension among young Indians aged 15–24 years. Between 2015–2016 and 2019–2021, the prevalence of prehypertension increased significantly (p < 0.001), rising from 38.9% to 44.5% among men and from 21.1% to 26.9% among women. While hypertension prevalence among men increased from 5.2% to 6.2%, it remained stable at approximately 4.0% among women over the same period. Most states, with a few exceptions, exhibited an increase in prehypertension prevalence across both genders, and more than two-thirds of states also showed an increase in hypertension prevalence among men. High BMI was found to be strongly associated with both prehypertension and hypertension. The rising prevalence of prehypertension and hypertension among young Indians aged 15–24 years is concerning and underscores the urgent need to develop targeted preventive strategies for this age group.

description: For most of the important processes in DNA metabolism, a protein has to reach a specific binding site on the DNA. The specific binding site may consist of just a few base pairs while the DNA is usually several millions of base pairs long. How does the protein search for the target site? What is the most efficient mechanism for a successful search? Motivated by these fundamental questions on intracellular biological processes, we have developed a model for searching a specific site on a model DNA by a single protein. We have made a comparative quantitative study of the efficiencies of sliding, inter-segmental hoppings and detachment/re-attachments of the particle during its search for the specific site on the DNA. We also introduce some new quantitative measures of {\it efficiency} of a search process by defining a relevant quantity, which can be measured in {\it in-vitro} experiments.

Describing and Analyzing the Gestures of Inorganic Chemistry Students Learning Symmetry and Group Theory
Creators: name: Markut, Jacob Jan
Publisher: name: University of Illinois at Chicago
Year: 2024

description: This dissertation discusses the gestures produced by students as they learn about the
inorganic chemistry topic of symmetry and group theory. Also included is an overview of the development and implementation of a symmetry and group theory laboratory activity, as well as an investigation seeking to promote gestural mimicry and uncover design suggestions for the inclusion of gesture in pedagogical spaces.
The conceptual framing of gesture here is in line with work by gesture studies
researchers such as David McNeil, Susan Goldin-Meadow, Elizabeth Wakefield, and
Geneviève Calbris. Specifically, there is a focus here on representational gestures, and
the analytical methodologies used are based on philosophical arguments that position
gesture as metaphor.
Data was collected to affirm that the developed symmetry and group theory laboratory
activity was successfully supporting relevant course-related pedagogical goals. During
this data collection, unanticipated student gestures were observed. A follow-on
investigation was conducted with the dual purpose of systematically describing the
gestural form of these gestures and uncovering correlations between gestural forms and
the underlying notion, or meaning, of the gestures. A novel gestural form coding
scheme was developed, influenced by Geneviève Calbris’ work. While the coding
scheme successfully characterized gestures in this context and trends were uncovered
for several symmetry elements and operations, gestures rarely embodied improper
rotation and inversion notions. This conclusion, along with literature supporting
gesture’s pedagogical potential and the phenomenon of gestural mimicry, prompted the
question: Could we support students learning about improper rotations and inversions
by having them mimic gestures used by their instructors? While we were unsuccessful
in promoting the occurrence of gestural mimicry, several design suggestions for the
inclusion of gesture in pedagogical spaces were uncovered.

description: The nature of changes in the interference pattern caused by the presence of polarization-changing elements in one or both beams of an interferometer, in particular those caused by an effective optical activity due to passage of a polarized beam through a coiled optical fiber are clarified. It is pointed out that for an incident state that is not circularly polarized so that the two interfering beams go to different polarization states, there is an observable nonzero Pancharatnam phase shift between them which depends on the incident polarization state and on the solid angle subtended by the track of the $\vec{k}$-vector at the centre of the sphere of k-vectors. The behaviour of this phase shift is singular when the two interfering states are nearly orthogonal. It is shown that for zero path difference between the two beams, the amplitude of intensity modulation as a function of optical activity is independent of the incident polarization state.

A new formulation of asset trading games in continuous time with essential forcing of variation exponent

description: We introduce a new formulation of asset trading games in continuous time in the framework of the game-theoretic probability established by Shafer and Vovk (Probability and Finance: It's Only a Game! (2001) Wiley). In our formulation, the market moves continuously, but an investor trades in discrete times, which can depend on the past path of the market. We prove that an investor can essentially force that the asset price path behaves with the variation exponent exactly equal to two. Our proof is based on embedding high-frequency discrete-time games into the continuous-time game and the use of the Bayesian strategy of Kumon, Takemura and Takeuchi (Stoch. Anal. Appl. 26 (2008) 1161--1180) for discrete-time coin-tossing games. We also show that the main growth part of the investor's capital processes is clearly described by the information quantities, which are derived from the Kullback--Leibler information with respect to the empirical fluctuation of the asset price.

description: Using the effective potential approach for composite operators, we have formulated a general method of calculation of the truly non-perturbative Yang-Mills vacuum energy density (this is, by definition, the Bag constant apart from the sign). It is the main dynamical characteristic of the QCD ground state. Our method allows one to make it free of the perturbative contributions ('contaminations'), by construction. We also perform an actual numerical calculation of the Bag constant for the confining effective charge. Its choice uniquely defines the Bag constant, which becomes free of all the types of the perturbative contributions now, as well as possessing many other desirable properties as colorless, gauge independence, etc. Using further the trace anomaly relation, we develop a general formalism which makes it possible to relate the Bag constant to the gluon condensate not using the weak coupling solution for the corresponding $β$ function. Our numerical result for the Bag constant shows a good agreement with other phenomenological estimates of the gluon condensate.

Distribution of periodic torus orbits and Duke's theorem for cubic fields

description: We study periodic torus orbits on spaces of lattices. Using the action of the group of adelic points of the underlying tori, we define a natural equivalence relation on these orbits, and show that the equivalence classes become uniformly distributed. This is a cubic analogue of Duke's theorem about the distribution of closed geodesics on the modular surface: suitably interpreted, the ideal classes of a cubic totally real field are equidistributed in the modular 5-fold SL_3(Z)\SL_3(R)/SO_3(R). In particular, this proves (a stronger form of) the folklore conjecture that the collection of maximal compact flats in SL_3(Z)\SL_3(R)/SO_3(R) of volume less than V becomes equidistributed as V goes to infinity. The proof combines subconvexity estimates, measure classification, and local harmonic analysis.

description: The drought of 1977 in much of the Midwest and Western United States again called attention to the need for improved management of our limited water resources in all segments of society. Water conservation concepts and practices for use on dry cropland with some interpretation on irrigated cropland are given for the west-central Great Plains. Strategies are discussed for improved water intake efficiency, including systems to upgrade the quality of summer fallow, snow control, reducing runoff water, irrigation, and deep plowing. Additional strategies are presented for improving water use by crops through soil fertility, better plant stock, matching plant populations with water supply, various cultural manipulations, and improved timing of irrigation. Wind and water erosion—brought about by prolonged drought—and their control are briefly outlined. Results show significant progress of many facets of water management at the research level, some of which have been transferred into commercial farming channels. The transfer of established and new water conservation concepts and practices for cropland will likely be faster and with greater diversity than in the past because of energy and economic pressures.
A characteristic approach to the quasi-normal mode problem

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we discuss a new approach to the quasinormal-mode problem in general relativity. By combining a characteristic formulation of the perturbation equations with the integration of a suitable phase-function for a complex valued radial coordinate, we reformulate the standard outgoing-wave boundary condition as a zero Dirichlet condition. This has a number of important advantages over previous strategies. The characteristic formulation permits coordinate compactification, which means that we can impose the boundary condition at future null infinity. The phase function avoids oscillatory behaviour in the solution, and the use of a complex radial variable allows a clean distinction between out- and ingoing waves. We demonstrate that the method is easy to implement, and that it leads to high precision numerical results. Finally, we argue that the method should generalise to the important problem of rapidly rotating neutron star spacetimes.

On the enumeration of complex plane curves with two singular points

description: We study equi-singular strata of plane curves with two singular points of prescribed types. The method of the previous work [Kerner06] is generalized to this case. In particular we consider the enumerative problem for plane curves with two singular points of linear singularity types. First the problem for two ordinary multiple points of fixed multiplicities is solved. Then the enumeration for arbitrary linear types is reduced to the case of ordinary multiple points and to the understanding of "merging" of singular points. Many examples and numerical answers are given.

description: We extend dynamic logic of propositional assignments by adding an operator of parallel composition that is inspired by separation logics. We provide an axiomatisation via reduction axioms, thereby establishing decidability. We also prove that the complexity of both the model checking and the satisfiability problem stay in PSPACE.
The magnetic fields of large Virgo Cluster spirals

description: Because of its proximity the Virgo Cluster is an excellent target for studying interactions of galaxies with the cluster environment. Both the high-velocity tidal interactions and effects of ram pressure stripping by the intracluster gas can be investigated. Optical and/or \ion{H}{i} observations do not always show effects of weak interactions between galaxies and their encounters with the cluster medium. For this reason we searched for possible anomalies in the magnetic field structure in Virgo Cluster spirals which could be attributed to perturbations in their gas distribution and kinematics. Five angularly large Virgo Cluster spiral galaxies (NGC 4501, NGC 4438, NGC 4535, NGC 4548 and NGC 4654) were the targets for a sensitive total power and polarization study using the 100-m radio telescope in Effelsberg at 4.85 GHz. For two objects polarization data at higher frequencies have been obtained allowing Faraday rotation analysis. Distorted magnetic field structures were identified in all galaxies. Interaction-induced magnetized outflows were found in NGC 4438 (due to nuclear activity) and NGC 4654 (a combination of tidal tails and ram pressure effects). Almost all objects (except the anaemic NGC 4548) exhibit distortions in polarized radio continuum attributable to influence of the ambient gas. For some galaxies they agree with observations of other species, but sometimes (NGC 4535) the magnetic field is the only tracer of the interaction with the cluster environment. The cluster environment clearly affects the evolution of the galaxies due to ram pressure and tidal effects. Magnetic fields provide a very long-lasting memory of past interactions. Therefore, they are a good tracer of weak interactions which are difficult to detect by other observations.

On the Distribution in Arithmetic Progressions of Primes of Various Properties Related to Elliptic Curves
Creators: name: Lee, Sung Min
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The primary focus of this thesis is the examination of the distribution in arithmetic progressions of primes of various properties related to elliptic curves. Following the introduction, the thesis comprises three distinct papers contributing to this central theme. In Section 2, we investigate the necessary and sufficient conditions for the absence of primes of cyclic reduction for an elliptic curve within an arithmetic progression, under GRH. This chapter represents collaborative research conducted with my advisor, Nathan Jones. Section 3 explores the statistical distribution of primes of cyclic reduction and m-divisibility for elliptic curves over congruence classes modulo n. This work stands as an independent contribution. Finally, Section 4 delves into the constants related to the cyclicity conjecture and Koblitz’s conjecture within arithmetic progressions. We provide explicit computations of these constants for Serre curves and propose upper bounds for non-Serre curves. This chapter represents collaborative research with Jacob Mayle and Tian Wang.
