Axonal collateralization of basolateral amygdala neurons
Creators: name: Kim, Ian Taehwan
Publisher: name: No Publisher Supplied

description: It was proposed that basolateral amygdala (BLA) neurons projecting to differentareas encode distinct types of information, allowing them to generate contrasting behaviors. Opposite to this view, other findings indicate that BLA neurons simultaneously encode a heterogenous mixture of sensory and behavioral variables, which might not segregate as a function of their projection sites given that a substantial proportion of BLA neurons send branching axons to multiple sites. To determine which of these views is correct, I recorded BLA neurons projecting to nucleus accumbens (nAc) or the medial prefrontal cortex (mPFC) during a task that requires rats to emit different appetitive or aversive behaviors based on the location of light stimuli on each trial. I found that BLA neurons projecting to distinct sites encode similar types of information. Next, I characterized the axon collateralization patterns of BLA neurons, about which very little was known. Using a viral tracing strategy that allows visualization of the axon collaterals contributed by different projection-defined BLA subpopulations, I found that BLA neurons projecting to the mPFC, anterior insula, nAc, or dorsal striatum (but not the ventral hippocampus or ventromedial hypothalamus) send massive collateral projections to a common array of subcortical structures. Last, I corroborated the existence of this profuse axonal collateralization using multiple fluorescent retrograde tracers.

description: Novel phases of two dimensional electron systems resulting from new surface or interface modified electronic structures have generated significant interest in material science. We utilize photoemission spectroscopy to show that the near-surface electronic structure of a bulk insulating iridate Sr$_3$Ir$_2$O$_7$ lying near metal-Mott insulator transition exhibit weak metallicity signified by finite electronic spectral weight at the Fermi level. The surface electrons exhibit a unique spin structure resulting from an interplay of spin-orbit, Coulomb interaction and surface quantum magnetism, distinct from a topological insulator state. Our results suggest the experimental realization of a novel quasi two dimensional interacting electron surface ground state, opening the door for exotic quantum entanglement and transport phenomena in iridate-based oxide devices.

description: We discuss a simple and fast method for estimating masses of early-type galaxies from optical data and compare the results with X-ray derived masses. The optical method relies only on the most basic observables such as the surface brightness $I(R)$ and the line-of-sight velocity dispersion $σ_p(R)$ profiles and provides an anisotropy-independent estimate of the galaxy circular speed $V_c$. The mass-anisotropy degeneracy is effectively overcome by evaluating $V_c$ at a characteristic radius $R_{\rm sweet}$ defined from {\it local} properties of observed profiles. The sweet radius $R_{\rm sweet}$ is expected to lie close to $R_2$, where $I(R) \propto R^{-2}$, and not far from the effective radius $R_{\rm eff}$. We apply the method to a sample of five X-ray bright elliptical galaxies observed with the 6-m telescope BTA-6 in Russia. We then compare the optical $V_c$-estimate with the X-ray derived value, and discuss possible constraints on the non-thermal pressure in the hot gas and configuration of stellar orbits. We find that the average ratio of the optical $V_c$-estimate to the X-ray one is equal to $\approx 0.98$ with $11 \%$ scatter, i.e. there is no evidence for the large non-thermal pressure contribution in the gas at $\sim R_{\rm sweet}$. From analysis of the Lick indices H$β$, Mgb, Fe5270 and Fe5335, we calculate the mass of the stellar component within the sweet radius. We conclude that a typical dark matter fraction inside $R_{\rm sweet}$ in the sample galaxies is $\sim 60\%$ for the Salpeter IMF and $\sim 75 \%$ for the Kroupa IMF.

description: We present a source catalogue and first results from a deep, blind radio survey carried out at 20 GHz with the Australia Telescope Compact Array, with follow-up observations at 5.5, 9 and 18 GHz. The Australia Telescope 20 GHz (AT20G) deep pilot survey covers a total area of 5 deg^2 in the Chandra Deep Field South and in Stripe 82 of the Sloan Digital Sky Survey. We estimate the survey to be 90% complete above 2.5 mJy. Of the 85 sources detected, 55% have steep spectra (alpha_{1.4}^{20} < -0.5) and 45% have flat or inverted spectra (alpha_{1.4}^{20} >= -0.5). The steep-spectrum sources tend to have single power-law spectra between 1.4 and 18 GHz, while the spectral indices of the flat- or inverted-spectrum sources tend to steepen with frequency. Among the 18 inverted-spectrum (alpha_{1.4}^{20} >= 0.0) sources, 10 have clearly defined peaks in their spectra with alpha_{1.4}^{5.5} > 0.15 and alpha_{9}^{18} < -0.15. On a 3-yr timescale, at least 10 sources varied by more than 15% at 20 GHz, showing that variability is still common at the low flux densities probed by the AT20G-deep pilot survey. We find a strong and puzzling shift in the typical spectral index of the 15-20 GHz source population when combining data from the AT20G, Ninth Cambridge and Tenth Cambridge surveys: there is a shift towards a steeper-spectrum population when going from ~1 Jy to ~5 mJy, which is followed by a shift back towards a flatter-spectrum population below ~5 mJy. The 5-GHz source-count model by Jackson & Wall (1999), which only includes contributions from FRI and FRII sources, and star-forming galaxies, does not reproduce the observed flattening of the flat-spectrum counts below ~5 mJy. It is therefore possible that another population of sources is contributing to this effect.

The castaways: affect, alienation, and authorship in American sitcoms of the 1960s
Creators: name: Durst, Lawrence Bruce
Publisher: name: No Publisher Supplied
Year: 2024

description: This dissertation reassesses a novel style of American sitcom that emerged in the mid-1960s in which serene depictions of suburbia that had dominated the genre in the late 1950s and early 1960s suddenly were populated by witches, Martians, genies, and other powerful alien characters. These programs were not only new in concept, they would make situation comedy the most popular genre on American TV. The central question guiding this study is: why did that specific new mode of comedy emerge at that particular moment? Much of the preceding scholarship interprets these sitcoms as reflections of the broad cultural disruptions of the era, including civil rights, feminism, consumerism, and the Cold War. What those readings overlook is a socioeconomic transition as crucial but less in the news: the transformation in the structure and control of American broadcasting. By the early 1960s, the three national networks had consolidated authority over the industry’s other functional parties—local broadcasters, advertisers, and independent program producers—just as television became the most powerful mass medium in the nation.This dissertation argues that the conceptual genesis of the programs was not in response to those broad societal changes but as projections of the shared anxieties experienced by their creators within their changing industry. While the programs resonated with audiences due to their culturally relatable themes and characters, they were conceived as personal expressions of their creators' struggles to maintain a sense of self-respect as they lost their former places of authority in the medium they helped create. Through intertextual analysis of the sitcoms alongside their creators’ published memoirs through the lens of Affect Theory, this dissertation explicates how the producers’ immediate concerns were encoded in the emotional reactions of their programs’ protagonists to the powerful outsiders who suddenly appeared in those characters’ lives.By recontextualizing these sitcoms within their creators’ historical industrial conditions, this study adds to current scholarship on the interconnectedness of creativity and media industry dynamics. It also reveals how the industry structures and relationships of a handful of television executives in the mid-twentieth century established the model of media control still in place today.

description: For every functional functor $F:Comp\to Comp$ in the category $Comp$ of compact Hausdorff spaces we define the notions of $F$-Dugundji and $F$-Milutin spaces, generalizing the classical notions of a Dugundji and Milutin spaces. We prove that the class of $F$-Dugundji spaces coincides with the class of absolute $F$-valued retracts. Next, we show that for a monomorphic continuous functor $F:Comp\to Comp$ admitting tensor products each Dugundji compact is an absolute $F$-valued retract if and only if the doubleton $\{0,1\}$ is an absolute $F$-valued retract if and only if some points $a\in F(\{0\})\subset F(\{0,1\})$ and $b\in F(\{1\})\subset F(\{0,1\})$ can be linked by a continuous path in $F(\{0,1\})$. We prove that for the functor $Lip_k$ of $k$-Lipschitz functionals with $k<2$, each absolute $Lip_k$-valued retract is openly generated. On the other hand the one-point compactification of any uncountable discrete space is not openly generated but is an absolute $Lip_3$-valued retract. More generally, each hereditarily paracompact scattered compact space $X$ of finite scattered height $n$ is an absolute $Lip_k$-valued retract for $k=2^{n+2}-1$.

description: We have characterized spin-squeezed states produced at a temperature of $26^\circ{\mathrm C}$ on a Nuclear Magnetic Resonance (NMR) quadrupolar system. The implementation is carried out in an ensemble of $^{133}$Cs nuclei with spin $I=7/2$ of a lyotropic liquid crystal sample. We identify the source of spin squeezing due to the interaction between the quadrupole moment of the nuclei and the electric field gradients internally present in the molecules. We use the spin angular momentum representation to describe formally the nonlinear operators that produce the spin squeezing. The quantitative and qualitatively characterization of the spin squeezing phenomena is performed through a squeezing parameter and squeezing angle developed for the two-mode BEC system, and, as well, by the Wigner quasi-probability distribution function. The generality of the present experimental scheme indicates its potential applications on solid state physics.

description: This research aims to survey the use rate of Marshall criteria into public relations by the librarians of Arak and Isfahan University of Medical Sciences. It was used the survey-descriptive method respectively. In order to gathering the research data it was used a researcher-made questionnaire this measured the use rate of 7 Marshall criteria (Budgeting, financial resources and gifts, informing the faculties and students, the more use of the library by the university people, improving the general viewpoint of academic community to the library, informing the non-academic community, and the more use of the library by the non-academic community) into public relations. The population included the librarians in the above mentioned universities out of which 86 ones sampled. For the validity, the viewpoints of experts were applied into the questionnaire. For the reliability Cronbach's alpha coefficient was calculated .987. In order to data analysis the SPSS 16 was used. The findings showed that in opinion of the librarians, applying of the public relations into 7 Marshall criteria was relatively favorable. In order to improving the conditions, experts should hold the educational courses on Public Relations
The Influence of Interactivity Features of Databases on Scientific Behavior: A user perspective survey based on the Flow theory
Publisher: name: Iranian Research Institute for Information Science and Technology (IranDoc)
Year: 2013

description: We followed two aims: testing the effects of databases' user interface interactivity (UII) on Scientific Behavior (SB) and exploring the flow experience (FE) as mediator between interface interactivity and SB, as well as self-efficacy (SE) role as an interferer. We used mixed method in this research. We made a SB questionnaire via a comparative literature study, FE and user UII through literature review. Faculty members and PhD students participated as scholars. Structural Equation Modeling was used for quantitative data analysis and interpretative approach to analyze qualitative data. The role of typological variables, such as gender, area of study, academic degree and English language skill level on SE, UII, FE and SB means are investigated. Finally, we tested the effects of databases' UII on SB and mediator role of FE and interfering role of SE. We found that the more self-efficient participants, the more they experience user interface interactivity and scientific behavior changes/adaptations. In other words, self-efficacy is an important characteristic to establish interactive search session and to upgrade scientific behavior in scholars. Also, we found those participants who experience more flow, have more chance to experience SB changes and adaptation in UII environment. So UII may have effect on researchers' SB. Results may be used in: 1) distance education or researcher training, since these areas are interested in developing, changing and adapting SB 2) Human-Computer Interaction field, because SB seems to be a new aspect of computer interaction effect on human 3) The Flow theory will be supported by this new implementation. We proposed a new theoretical framework for research
Errors in Scale Values for Magnetic Elements for Helsinki

description: Using several lines of evidence we show that the scale values of the geomagnetic variometers operating in Helsinki in the 19th century were not constant throughout the years of operation 1844-1897. Specifically, the adopted scale value of the Horizontal Force variometer appears to be too low by ~30% during the years 1866-1874.5 and the adopted scale value of the Declination variometer appears to be too low by a factor of ~2 during the interval 1885.8-1887.5. Reconstructing the Heliospheric Magnetic Field strength from geomagnetic data has reached a stage where a reliable reconstruction is possible using even just a single geomagnetic data set of hourly or daily values. Before such reconstructions can be accepted as reliable, the underlying data must be calibrated correctly. It is thus mandatory that the Helsinki data be corrected. Such correction has been satisfactorily carried out and the HMF strength is now well constrained back to 1845.

description: This thesis presents two novel modifications to a gesture recognition systemfor virtual reality devices and applications. In doing this it evaluates usersmovements in VR when presented with gestures and uses this information todevelop a continuous tracking system that can detect the start and end of gestures.It also expands on previous work with gestures in games with an implementationof an adaptive database system that has been seen to improve accuracy rates.The database allows users to immediately start using the system with no priortraining and will improve accuracy rates as they spend more time in the game.Furthermore it evaluates both the explicit and continuous recognition systemsthrough user based studies. The results from these studies show promise for theusability of gesture based interaction systems for VR devices in the future. Theyalso provide findings that suggest that for the use case of games continuous systemcould be too cumbersome for users.

description: We investigate how the observed large-scale surface magnetic fields of low-mass stars (~0.1 -- 2 Msun), reconstructed through Zeeman-Doppler imaging (ZDI), vary with age t, rotation and X-ray emission. Our sample consists of 104 magnetic maps of 73 stars, from accreting pre-main sequence to main-sequence objects (1 Myr < t < 10 Gyr). For non-accreting dwarfs we empirically find that the unsigned average large-scale surface field is related to age as $t^{-0.655 \pm 0.045}$. This relation has a similar dependence to that identified by Skumanich (1972), used as the basis for gyrochronology. Likewise, our relation could be used as an age-dating method ("magnetochronology"). The trends with rotation we find for the large-scale stellar magnetism are consistent with the trends found from Zeeman broadening measurements (sensitive to large- and small-scale fields). These similarities indicate that the fields recovered from both techniques are coupled to each other, suggesting that small- and large-scale fields could share the same dynamo field generation processes. For the accreting objects, fewer statistically significant relations are found, with one being a correlation between the unsigned magnetic flux and rotation period. We attribute this to a signature of star-disc interaction, rather than being driven by the dynamo.

description:
Down syndrome (Ds) is a genetic disorder characterized by the autosomal abnormality of a third copy of chromosome 21. Due to the physical and intellectual disabilities that many people with Ds experience, they often need support with (instrumental) activities of daily living. Since adults with Ds are living longer, it is important to determine how exercise can affect mobility and quality of life in the Ds community. The impact on more functional outcomes, such as level of support and quality of life has not been systematically investigated. Therefore, the aim was to investigate whether twelve weeks of a remote, structured exercise program will decrease the need of support provided by caregivers and increase quality of life compared to those doing usual activities. The participants were randomly assigned to a 12-week exercise intervention or a control condition. The exercise intervention was based on the Mann Method PT and consisted of a one-hour exercise session 3 times per week, conducted via Zoom, while the participants in the control condition continued their usual activities. All participants were evaluated before and after the 12 weeks using the following assessments: Supports Intensity Scale for Adults (SIS-A) and Health-Related Quality of Life (HRQoL-IDD). The baseline level of support varied between participants, with no participant being fully dependent. This study did not confirm or reject our hypotheses on the effects of an exercise program when measuring level of support and quality of life in adults with Ds, and further research is necessary to further elucidate this question.

description: We consider a description of the stochastic oscillations of the general relativistic accretion disks around compact astrophysical objects interacting with their external medium based on a generalized Langevin equation with colored noise, which accounts for the general memory and retarded effects of the frictional force, and on the fluctuation-dissipation theorem. The presence of the memory effects influences the response of the disk to external random interactions, and modifies the dynamical behavior of the disk, as well as the energy dissipation processes. The generalized Langevin equation of the motion of the disk in the vertical direction is studied numerically, and the vertical displacements, velocities and luminosities of the stochastically perturbed disks are explicitly obtained for both the Schwarzschild and the Kerr cases. The Power Spectral Distribution (PSD) of the disk luminosity is also obtained. As a possible astrophysical application of the formalism we investigate the possibility that the Intra Day Variability (IDV) of the Active Galactic Nuclei (AGN) may be due to the stochastic disk instabilities. The perturbations due to colored/nontrivially correlated noise induce a complicated disk dynamics, which could explain some astrophysical observational features related to disk variability.

description: This poster explores the initiatives, stakeholders, and contributions shaping the research culture discourse in the UK, driven by the redesigned national research assessment exercise and its emphasis on rewarding positive research environments. While related articles and events emerged seven years ago, their depth and variety have increased substantially in recent years. The study reveals a diverse array of actors engaged in research culture discussions and examines trends in research culture topics alongside the higher education sector's response: job postings, teams’ size and profile. The analysis highlights which are the themes that universities are focusing on, what initiatives, policies, activities and events are at the core of the research culture and how open are these discussions. While the rise of the research culture in UK is parallel to and linked with the rise of the open research agenda, the emerging evaluating indicators are signalling a broader shift in research assessment practices.

description: Background and objectives:Multiple Sclerosis is a common relapsing demyelinating diseasecausing the significant degradation of cognitive and motor skills and contributes towards areduced life expectancy of 5 to 10 years. The identification of Multiple Sclerosis Lesionsat early stages of a patient’s life can play a significant role in the diagnosis, treatment andprognosis for that individual. In recent years the process of disease detection has been aidedthrough the implementation of radiomic pipelines for texture extraction and classificationutilising Computer Vision and Machine Learning techniques.Eight Multiple Sclerosis Patient datasets have been supplied, each containing one standardclinical T2 MRI sequence and four diffusion-weighted sequences (T2, FA, ADC, AD, RD).This work proposes a Multimodal Multiple Sclerosis Lesion segmentation methodology util-ising supervised texture analysis, feature selection and classification. Three Machine Learningmodels were applied to Multimodal MRI data and tested using unseen patient datasets to eval-uate the classification performance of various extracted features, feature selection algorithmsand classifiers to MRI volumes uncommonly applied to MS Lesion detection.Method: First Order Statistics, Haralick Texture Features, Gray-Level Run-Lengths, His-togram of Oriented Gradients and Local Binary Patterns were extracted from MRI volumeswhich were minimally pre-processed using a skull stripping and background removal algorithm.mRMR and LASSO feature selection algorithms were applied to identify a subset of rankingsfor use in Machine Learning using Support Vector Machine, Random Forests and ExtremeLearning Machine classification.Results: ELM achieved a top slice classification accuracy of 85% while SVM achieved 79%and RF 78%. It was found that combining information from all MRI sequences increased theclassification performance when analysing unseen T2 scans in almost all cases. LASSO andmRMR feature selection methods failed to increase accuracy, and the highest-scoring groupof features were Haralick Texture Features, derived from Grey-Level Co-occurrence matrices.

description: Analogues of the classical Banach-Stone theorem for spaces of continuous functions are studied in the context of the spaces of absolutely continuous functions introduced by Ashton and Doust. We show that if $AC(σ_1)$ is algebra isomorphic to $AC(σ_2)$ then $σ_1$ is homeomorphic to $σ_2$. The converse however is false. In a positive direction we show that the converse implication does hold if the sets $σ_1$ and $σ_2$ are confined to a restricted collection of compact sets, such as the set of all simple polygons.

Fractal Oncology: A Theory of Membrane Polarity Collapse and Interventional Applications
Creators: name: Dr. Mavrogeorgis, Dimitrios
Publisher: name: Zenodo
Year: 2025

description: This working paper introduces the Fractal Oncology model, a conceptual framework proposing that cancer may originate from a collapse in the fractal structure and functional polarity of the cell membrane. According to this hypothesis, the disintegration of spatial order within the membrane leads to biological disconnection, loss of environmental coherence, and autonomous cellular behavior characteristic of malignancy.

Two experimental membrane-centered therapeutic strategies are also presented as complementary to the model:

1. **Membrane Thermal Reprogramming** – The application of thermal or cryogenic influence on the cell membrane to restore or disrupt lipid raft dynamics and membrane polarity.     Zenodo Reference: https://zenodo.org/records/15213112

2. **Healthy Membrane Material Grafting** – The conceptual transfer of functional membrane components from healthy cells to malignant ones, aiming to reintroduce organizational signals and re-establish regulatory coherence.     Zenodo Reference: https://zenodo.org/records/15212728

These strategies are presented purely as theoretical contributions, meant to inspire future biomedical research.

Subjects: I100 - Computer science

description: In recent years the aviation industry has begun to embrace digital technology forAir Traffic Control (ATC) radio systems. This change has created challenges not onlyfor the industry but also for personnel. However, this implementation offers manyimprovements over older systems; more precise control, straightforward integrationwith other ATC systems and a more efficient way to provide software updates. Thechallenge for personnel is to develop a new skillset enabling a learning transitionfrom analogue to digital systems, with a specific emphasis on computer networkingskills.This project was undertaken in collaboration between the University of Lincoln(UoL) and Park Air Systems (PAS), an industry-leading provider of Air-Space com-munication solutions. A system has been developed to find a mechanism to monitorand visualise network traffic. The use of graphs provides a direct interface for theend-users, enabling a mechanism for identifying performance issues to meet thetransitional challenges from analogue to digital. An easy to use interface has beendesigned, which will enable non-technical users to interact effectively with the sys-tem.Considerable testing was undertaken to investigate the system usability concern-ing the practical application for users with limited networking experience. A surveyprovided a range of quantitative and qualitative data which was further analysed toscrutinize user perspectives on system usability. This involved engineers from PASand postgraduate students from UoL to compare results between direct industrypersonnel and unaffiliated participants.

description: Motivated by the increasing use of and rapid changes in array technologies, we consider the prediction problem of fitting a linear regression relating a continuous outcome $Y$ to a large number of covariates $\mathbf {X}$, for example, measurements from current, state-of-the-art technology. For most of the samples, only the outcome $Y$ and surrogate covariates, $\mathbf {W}$, are available. These surrogates may be data from prior studies using older technologies. Owing to the dimension of the problem and the large fraction of missing information, a critical issue is appropriate shrinkage of model parameters for an optimal bias-variance trade-off. We discuss a variety of fully Bayesian and Empirical Bayes algorithms which account for uncertainty in the missing data and adaptively shrink parameter estimates for superior prediction. These methods are evaluated via a comprehensive simulation study. In addition, we apply our methods to a lung cancer data set, predicting survival time ($Y$) using qRT-PCR ($\mathbf {X}$) and microarray ($\mathbf {W}$) measurements.

description: The focal-plane camera of $γ$-ray telescopes frequently uses light concentrators in front of light sensors. The purpose of these concentrators is to increase the effective area of the camera as well as to reduce the stray light coming at large incident angles. These light concentrators are usually based on the Winston cone design. In this contribution we present the design of an hexagonal hollow light concentrator with a lateral profile optimized using a cubic Bézier function to achieve a higher collection efficiency in the angular region of interest. The design presented here is optimized for a Davies-Cotton telescope with primary mirror of about 4 meters of diameter and focal length of 5.6 m. The described concentrators are part of an innovative camera made up of silicon-photomultipliers sensors, although a similar approach can be used for other sizes of single-mirror telescopes with different camera sensors, including photomultipliers. The challenge of our approach is to achieve a cost-effective design suitable for standard industrial productions of both the plastic concentrator substrate and the reflective coating. At the same time we maximize the optical performance. In this paper we also describe the optical set-up to measure the absolute collection efficiency of the light guides and demonstrate our good understanding of the measured data using a professional light tracing simulation.

description: Embedded system software is highly constrained from performance, memory footprint, energy consumption and implementing cost view point. It is always desirable to obtain better Instructions per Cycle. Instruction cache has major contribution in improving IPC. Cache memories are realized on the same chip where the processor is running. This considerably increases the system cost as well. Hence, it is required to maintain a trade off between cache sizes and performance improvement offered. Determining the number of cache lines and size of cache line are important parameters for cache designing. The design space for cache is quite large. It is time taking to execute the given application with different cache sizes on an instruction set simulator to figure out the optimal cache size. In this paper, a technique is proposed to identify a number of cache lines and cache line size for the L1 instruction cache that will offer best or nearly best IPC. Cache size is derived, at a higher abstraction level, from basic block analysis in the Low Level Virtual Machine environment. The cache size estimated is cross validated by simulating the set of benchmark applications with different cache sizes in simple scalar simulator. The proposed method seems to be superior in terms of estimation accuracy and estimation time as compared to the existing methods for estimation of optimal cache size parameters like cache line size, number of cache lines.

description: We show how a variety of stable spatio-temporal periodic patterns can be created in 2D-lattices of coupled oscillators with non-homogeneous coupling delays. A "hybrid dispersion relation" is introduced, which allows studying the stability of time-periodic patterns analytically in the limit of large delay. The results are illustrated using the FitzHugh-Nagumo coupled neurons as well as coupled limit cycle (Stuart-Landau) oscillators.
