description: We reexamine interactions between the dark sectors of cosmology, with a focus on robust constraints that can be obtained using only mildly nonlinear scales. While it is well known that couplings between dark matter and dark energy can be constrained to the percent level when including the full range of scales probed by future optical surveys, calibrating matter power spectrum emulators to all possible choices of potentials and couplings requires many computationally expensive n-body simulations. Here we show that lensing and clustering of galaxies in combination with the Cosmic Microwave Background (CMB) is capable of probing the dark sector coupling to the few percent level for a given class of models, using only linear and quasi-linear Fourier modes. These scales can, in principle, be described by semi-analytical techniques such as the effective field theory of large-scale structure.

Cold-Water-Immersion and the Influence of Dynamic Balance Task and Postural Sway
Creators: name: Burke, Jonathan Michael
Publisher: name: University of Utah
Year: 2019
Subjects: Physical therapy

description: Ankle sprains in an athletic setting are considered one of the most common injuries sustained. Cryokinetics is commonly used in the treatment of these injuries. Recent literature suggests dynamic balance rehabilitation is influential for faster return to functional activity. Limited research has been published on the influence Cold-Water- Immersion (CWI) has on dynamic balance performance at the ankle. We evaluate CWI influence on a modified y-balance test and postural sway. We anticipated no significant differences between a treatment and control. Alpha was set at ≤ 0.05. A crossover design was utilized with a randomized treatment and control day along with randomized reach direction. Data collection was performed in a research laboratory setting with thirty subjects (female=15 male=15, age= 24±1.5 years, ht =172.75 cm±8.0, mass=70.8±12.8 kg). Study took place over two separate data collection days consisting of treatment and control. Treatment included subjects placing the nondominant lower leg into a container of cold water (maintained between 0 - 5 °C) for a minimum of 10 minutes and maximum of 15 minutes along with self reported numbness. Post treatment, subjects were asked to perform a modified y-balance test on a force plate. If numbness was lost during testing, the subject placed the lower leg back into the container for a minimum of 5 minutes and self-reported numbness. Normalized reach direction in the anterior (ANT), posteromedial (PM), and posterolateral (PL) were recorded with an intratester reliability of (0.67-0.96). Center of Pressure (COP) excursions of means velocity squared via forceplate was calculated with anterior/posterior (R=0.86) and medial/lateral (R=0.81) values. Normalized reach and COP measures were compared using RMANOVA. There was no significant within-subject interaction on all variables [Wilks' Λ=0.70, F (df) = 0.999, p = 0.471]. ANT reach presented closest to significance and largest effect size [F=2.51, p = 0.123, effect size = 0.33]. However, subjects self-reported an increased difficulty during testing. Measures indicate no significant difference in performance of the dynamic balance task. This may reinforce earlier dynamic balance rehabilitation of acute ankle sprains. With a faster introduction to rehabilitative exercises, athletes may minimize the long-lasting effects experienced from acute ankle sprains. Further research should evaluate the effect dynamic balance has on an injured population.

description: In this work, we study the problem of learning the volatility under market microstructure noise. Specifically, we consider noisy discrete time observations from a stochastic differential equation and develop a novel computational method to learn the diffusion coefficient of the equation. We take a nonparametric Bayesian approach, where we \emph{a priori} model the volatility function as piecewise constant. Its prior is specified via the inverse Gamma Markov chain. Sampling from the posterior is accomplished by incorporating the Forward Filtering Backward Simulation algorithm in the Gibbs sampler. Good performance of the method is demonstrated on two representative synthetic data examples. We also apply the method on a EUR/USD exchange rate dataset. Finally we present a limit result on the prior distribution.

description: We present the first experimental discrimination between the 2e/3 and 4e/3 top quark electric charge scenarios, using top quark pairs (ttbar) produced in ppbar collisions at sqrt{s}=1.96 TeV by the Fermilab Tevatron collider. We use 370 pb-1 of data collected by the D0 experiment and select events with at least one high transverse momentum electron or muon, high transverse energy imbalance, and four or more jets. We discriminate between b- and bbar-quark jets by using the charge and momenta of tracks within the jet cones. The data is consistent with the expected electric charge, |q|=2e/3. We exclude, at the 92% C.L., that the sample is solely due to the production of exotic quark pairs QQbar with |q|=4e/3. We place an upper limit on the fraction of QQbar pairs fq < 0.80 at the 90% C.L.

description: We present, in an explicit form, the metric for all spherically symmetric Schwarzschild-Bach black holes in Einstein-Weyl theory. In addition to the black hole mass, this complete family of spacetimes involves a parameter that encodes the value of the Bach tensor on the horizon. When this additional "non-Schwarzschild parameter" is set to zero the Bach tensor vanishes everywhere and the "Schwa-Bach" solution reduces to the standard Schwarzschild metric of general relativity. Compared with previous studies, which were mainly based on numerical integration of a complicated form of field equations, the new form of the metric enables us to easily investigate geometrical and physical properties of these black holes, such as specific tidal effects on test particles, caused by the presence of the Bach tensor, as well as fundamental thermodynamical quantities.

description: Global climate change and the implementation of energy technologies are among the most pressing issues facing society and the environment today. Related educational content spans the science disciplines. Through an analysis of introductory-level university textbooks from four major US publishers in Biology, Chemistry, and Physics, this study presents trends in terminology and content. As the defining terms, “global warming” and “climate change” are used nearly equally. However, the first location of a working definition for climate change appears earlier. Energy technologies, climate change, and related environmental issues are found, on average, on ≤4% of textbook pages, and variation is large among individual textbooks. Discipline-based trends exist, especially for the energy technologies presented. Addressed separately as a non-renewable, non-fossil fuel, nuclear energy is found on ≤1% of textbook pages and unfavorably represented. The discussion within these science disciplines has implications on introductory-level education, public perception of science, and informed citizenship.

description: The main goal of this dissertation is to identify major characteristics of French colonial education in Soudan Francais (present day Mali) before discussing ways in which, despite major education reforms, legacies that relate to those characteristics continue to, either consciously or unconsciously, be reproduced, altered, or challenged in two current higher education teacher-training programs in postcolonial Mali. The discussions offer insights with regard to how issues of reproduction, hybridity, and resistance play out in various data sources before examining ways in which they affect the subjectivities of preservice teachers graduating from the two teacher training programs investigated. Data were collected from a wide range of sources, which include colonial and postcolonial legislations and documents, textbooks, retired and preservice teachers' responses to questionnaires, and Skype interviews of a focus group of preservice teachers. Methods of content analysis and narrative analysis were used to make sense of data collected while simultaneously calling in major concepts from postcolonial theory for a broader analysis and discussion. The analysis and discussion of data collected revealed multiple instances of reproduction, resistance, and hybridity within the two departments, thereby positioning graduating preservice teachers to be likely to engage in similar practices potentially resulting in similar instances in their own future classrooms. Whether related to current, retired, or preservice teachers, it appeared that instances of reproduction, resistance, and hybridity sometimes occurred deliberately, though often times not deliberately. The concluding section of this dissertation offers some possible pathways for Malian stakeholders to examine in order to address major educational issues that were revealed throughout this study.

description: The characterization problem of the existence of an unknown obstacle behind a known obstacle is considered by using a singe observed wave at a place where the wave is generated. The unknown obstacle is invisible from the place by using visible ray. A mathematical formulation of the problem using the classical wave equation is given. The main result consists of two parts: (i) one can make a decision whether the unknown obstacle exists or not behind a known impenetrable obstacle by using a single wave over a finite time interval under some a-priori information on the position of the unknown obstacle; (ii) one can obtain a lower bound of the Euclidean distance of the unknown obstacle to the center point of the support of the initial data of the wave. The proof is based on the idea of the time domain enclosure method and employs some previous results on the Gaussian lower/upper estimates for the heat kernels and domination of semigroups.

description: The shuffle product has a connection with several useful permutation statistics such as descent and peak, and corresponds to the multiplication operation in the corresponding descent and peak algebras. In their recent work, Gessel and Zhuang formalized the notion of shuffle-compatibility and studied various permutation statistics from this viewpoint. They further conjectured that any shuffle compatible permutation statistic is a descent statistic. In this note we construct a counter-example to this conjecture.

description: We present a catalog of early-time (~10^2-10^4s) photometry and polarimetry of all Gamma-Ray Burst (GRB) optical afterglows observed with RINGO2 imaging polarimeter on the Liverpool Telescope. For the 19 optical afterglows observed, the following 9 were bright enough to perform photometry and attempt polarimetry: GRB 100805A, GRB 101112A, GRB 110205A, GRB 110726A, GRB 120119A, GRB 120308A, GRB 120311A, GRB 120326A and GRB 120327A. We present multi-wavelength light curves for these 9 GRBs, together with estimates of their optical polarization degrees and/or limits. We carry out a thorough investigation of detection probabilities, instrumental properties and systematics. Using two independent methods, we confirm previous reports of significant polarization in GRB 110205A and 120308A, and report new detection of $P=6^{+3}_{-2}\%$ in GRB101112A. We discuss the results for the sample in the context of the reverse and forward shock afterglow scenario, and show that GRBs with detectable optical polarization at early time have clearly identifiable signatures of reverse-shock emission in their optical light curves. This supports the idea that GRB ejecta contain large-scale magnetic fields and highlights the importance of rapid-response polarimetry.

Combination Nanomedicine Targeting Cancer Stem Cells and Bulk Tumor Cells for Treatment of Prostate Cancer
Creators: name: Zhou, Yan
Publisher: name: University of Utah
Year: 2019

description: Prostate cancer is the most common malignancy and second leading cause of cancer-related deaths in men in the United States. Despite improved management of patients with early stage prostate cancer, the mortality rate is still high due to frequent relapse, progression and metastasis following current antiprostate cancer therapies. Recently, research evidences support the presence of a subpopulation of cancer stem cells (CSCs) with infinite self-renewal and differentiation abilities. These drug-resistant CSCs, surviving following traditional anticancer therapies, contribute to cancer recurrence and metastasis. Therefore, to overcome the failure of current therapies and improve prostate cancer patient outcomes, it is necessary to not only shrink the tumor mass, but also inhibit CSC growth and maintenance. To this end, we designed the combination macromolecular therapeutics containing two types of HPMA copolymer-drug conjugates: one effectively killing non-CSC bulk tumor cells, the other preferentially killing prostate CSCs. Docetaxel, a first line chemotherapeutic agent for advanced prostate cancer, is employed in the bulk tumor cell-killing HPMA copolymer-drug conjugate. Cyclopamine (a hedgehog pathway inhibitor) or GDC-0980 (a PI3K/mTOR dual inhibitor), with antiprostate CSC activity, is incorporated in the CSC-killing conjugate. The two types of HPMA copolymer-drug conjugates were synthesized by RAFT (reverse addition-fragmentation chain-transfer) copolymerization, with well controlled molecular weight and narrow molecular weight distribution. The anti-CSC and antibulk tumor effects of individual and combination of the two HPMA copolymer-drug conjugates were evaluated in vitro and in vivo. The in vitro evaluations show that the CSC-killing conjugate decreased the relative amount of CD133+ prostate CSC enriched population and impaired prostasphere forming ability. On the other hand, HPMA copolymer-docetaxel conjugate failed to decrease the relative amount of CD133+ cancer cells. The combination treatment led to the strongest tumor growth inhibition in long-term. For the in vivo evaluations, single and combination treatment all inhibited tumor growth immediately in PC-3 prostate tumor bearing mice. However, only the combination therapy led to sustained tumor growth inhibition in long-term. The characterizations of residual tumor cells suggest a decreased proportion of CD133+ cells following combination therapy.

Microwave emission from a crystal of molecular magnets -- The role of a resonant cavity

description: We discuss the effects caused by a resonant cavity around a sample of a magnetic molecular crystal (such as Mn${}_{12}$-Ac), when a time dependent external magnetic field is applied parallel to the easy axis of the crystal. We show that the back action of the cavity field on the sample significantly increases the possibility of microwave emission. This radiation process can be supperradiance or a maser-like effect, depending on the strength of the dephasing. Our model provides further insight to the theoretical understanding of the bursts of electromagnetic radiation observed in recent experiments accompanying the resonant quantum tunneling of magnetization. The experimental findings up to now can all be explained as being a maser effect rather than superradiance. The results of our theory scale similarly to the experimental findings, i.e., with increasing sweep rate of the external magnetic field, the emission peaks are shifted towards higher field values.

Then we discuss the dimensional reduction of the GPE from 3D to 1D, deriving the 1D GPE and also the 1D nonpolynomial Schrödinger equation (1D NPSE). Finally, we analyze the bright solition solutions of both 1D GPE and 1D NPSE and compare these theoretical predictions with the available experimental data.

description: Shoes are ubiquitous, serving as protection, status, personal statement and health aid. For more than 10,000 years, people have worn shoes to insulate their feet from the surrounding environment, which includes extreme temperatures, ground surface conditions, or unwanted impact. Shoes have reflected fashion, station, age, power and status for centuries. They also serve the function of enhancing performance in various activities, be it walking for the physically disabled, running for the Olympian, or providing protection for the farmer. Overall, shoes serve the same functions today as they have for more than 10,000 years. While materials used in the shoe and the manufacturing processes have evolved and changed over the years, the foot has not, nor have the fundamental reasons for using footwear. In fact, shoes constructed centuries ago might still be worn, functioning as was intended originally. Could shoes have added features and function in new ways? Our team believes this is possible primarily due to the advent of powerful microprocessors and new technology which enhances development of new materials and manufacturing techniques. Emerging wearable technology is aiming to make people’s lives better and smart footwear must follow suit.

Berca International, an Indonesian shoe manufacturing and distribution concern, tasked the combined interdisciplinary design team composed of graduate students from Stanford and Aalto Universities to innovate novel approaches to smart footwear as part of ME310, a graduate course in design. The goal is to develop a new approach to smart footwear that will allow Berca International to penetrate the U.S. by differentiating it from the competition. With the wide range of disciplines, ranging from mechanical engineering, computer science and mechatronics to entrepreneurship and design research, the design team is ready to take on Berca’s challenge.

description: We address side-channel leakage in a trusted preparation station of continuous-variable quantum key distribution with coherent and squeezed states. We consider two different scenaria: multimode Gaussian modulation, directly accessible to an eavesdropper, or side-channel loss of the signal states prior to the modulation stage. We show the negative impact of excessive modulation on both the coherent- and squeezed-state protocols. The impact is more pronounced for squeezed-state protocols and may require optimization of squeezing in the case of noisy quantum channels. Further, we demonstrate that coherent-state protocol is immune to side-channel signal state leakage prior to modulation, while the squeezed-state protocol is vulnerable to such attacks, becoming more sensitive to the noise in the channel. In the general case of noisy quantum channels the signal squeezing can be optimized to provide best performance of the protocol in the presence of side-channel leakage prior to modulation. Our results demonstrate that leakage from the trusted source in continuous-variable quantum key distribution should not be underestimated and squeezing optimization is needed to overcome coherent state protocols.

Final-state QED Multipole Radiation in Antenna Parton Showers

description: We present a formalism for a fully coherent QED parton shower. The complete multipole structure of photonic radiation is incorporated in a single branching kernel. The regular on-shell 2 to 3 kinematic picture is kept intact by dividing the radiative phase space into sectors, allowing for a definition of the ordering variable that is similar to QCD antenna showers. A modified version of the Sudakov veto algorithm is discussed that increases performance at the cost of the introduction of weighted events. Due to the absence of a soft singularity, the formalism for photon splitting is very similar to the QCD analogon of gluon splitting. However, since no color structure is available to guide the selection of a spectator, a weighted selection procedure from all available spectators is introduced.

description: The equality in the uncertainty principle for linear momentum and position is obtained for states which also minimize the uncertainty product. However, in the uncertainty relation for angular momentum and angular position both sides of the inequality are state dependent and therefore the intelligent states, which satisfy the equality, do not necessarily give a minimum for the uncertainty product. In this paper, we highlight the difference between intelligent states and minimum uncertainty states by investigating a class of intelligent states which obey the equality in the angular uncertainty relation while having an arbitrarily large uncertainty product. To develop an understanding for the uncertainties of angle and angular momentum for the large-uncertainty intelligent states we compare exact solutions with analytical approximations in two limiting cases.

description: In this paper we prove the global convergence of the complex Jacobi method for Hermitian matrices for a large class of generalized serial pivot strategies. For a given Hermitian matrix $A$ of order $n$ we find a constant $γ<1$ depending on $n$, such that $S(A')\leqγ{S(A)}$, where $A'$ is obtained from $A$ by applying one or more cycles of the Jacobi method and $S(\cdot)$ stands for the off-norm. Using the theory of complex Jacobi operators, the result is generalized so it can be used for proving convergence of more general Jacobi-type processes. In particular, we use it to prove the global convergence of Cholesky-Jacobi method for solving the positive definite generalized eigenvalue problem.

description: We study the dust concentration and emission in protoplanetary disks vortices. We extend the Lyra-Lin solution for the dust concentration of a single grain size to a power-law distribution of grain sizes $n(a) \propto a^{-p}$. Assuming dust conservation in the disk, we find an analytic dust surface density as a function of the grain radius. We calculate the increase of the dust to gas mass ratio $ε$ and the slope $p$ of the dust size distribution due to grain segregation within the vortex. We apply this model to a numerical simulation of a disk containing a persistent vortex. Due to the accumulation of large grains towards the vortex center, $ε$ increases by a factor of 10 from the background disk value, and $p$ decreases from 3.5 to 3.0. We find the disk emission at millimeter wavelengths corresponding to synthetic observations with ALMA and VLA. The simulated maps at 7 mm and 1 cm show a strong azimuthal asymmetry. This happens because, at these wavelengths, the disk becomes optically thin while the vortex remains optically thick. The large vortex opacity is mainly due to an increase in the dust to gas mass ratio. In addition, the change in the slope of the dust size distribution increases the opacity by a factor of 2. We also show that the inclusion of the dust scattering opacity substantially changes the disks images.

description: We discuss some aspects of F-theory in four dimensions on elliptically fibered Calabi-Yau fourfolds which are Calabi-Yau threefold fibrations. A particularly simple class of such manifolds emerges for fourfolds in which the generic Calabi-Yau threefold fiber is itself an elliptic fibration and is K3 fibered. Duality between F-theory compactified on Calabi-Yau fourfolds and heterotic strings on Calabi-Yau threefolds puts constraints on the cohomology of the fourfold. By computing the Hodge diamond of Calabi-Yau fourfolds we provide first numerical evidence for F-theory dualities in four dimensions.

description: Biomedical image segmentation plays a central role in quantitative analysis, clinical diagnosis, and medical intervention. In the light of the fully convolutional networks (FCN) and U-Net, deep convolutional networks (DNNs) have made significant contributions to biomedical image segmentation applications. In this paper, we propose three different multi-scale dense connections (MDC) for the encoder, the decoder of U-shaped architectures, and across them. Based on three dense connections, we propose a multi-scale densely connected U-Net (MDU-Net) for biomedical image segmentation. MDU-Net directly fuses the neighboring feature maps with different scales from both higher layers and lower layers to strengthen feature propagation in the current layer. Multi-scale dense connections, which contain shorter connections between layers close to the input and output, also make a much deeper U-Net possible. Besides, we introduce quantization to alleviate the potential overfitting in dense connections, and further improve the segmentation performance. We evaluate our proposed model on the MICCAI 2015 Gland Segmentation (GlaS) dataset. The three MDC improve U-Net performance by up to 1.8% on test A and 3.5% on test B in the MICCAI Gland dataset. Meanwhile, the MDU-Net with quantization obviously improves the segmentation performance of original U-Net.

description: We study the two-dimensional Ising model on a network with a novel type of quenched topological (connectivity) disorder. We construct random lattices of constant coordination number and perform large scale Monte Carlo simulations in order to obtain critical exponents using finite-size scaling relations. We find disorder-dependent effective critical exponents, similar to diluted models, showing thus no clear universal behavior. Considering the very recent results for the two-dimensional Ising model on proximity graphs and the coordination number correlation analysis suggested by Barghathi and Vojta (2014), our results indicate that the planarity and connectedness of the lattice play an important role on deciding whether the phase transition is stable against quenched topological disorder.

description: Optical flow techniques are becoming increasingly performant and robust when estimating motion in a scene, but their performance has yet to be proven in the area of facial expression recognition. In this work, a variety of optical flow approaches are evaluated across multiple facial expression datasets, so as to provide a consistent performance evaluation. The aim of this work is not to propose a new expression recognition technique, but to understand better the adequacy of existing state-of-the art optical flow for encoding facial motion in the context of facial expression recognition. Our evaluations highlight the fact that motion approximation methods used to overcome motion discontinuities have a significant impact when optical flows are used to characterize facial expressions.
An HLLC Riemann Solver for Relativistic Flows: I. Hydrodynamics

description: We present an extension of the HLLC approximate Riemann solver by Toro, Spruce and Speares to the relativistic equations of fluid dynamics. The solver retains the simplicity of the original two-wave formulation proposed by Harten, Lax and van Leer (HLL) but it restores the missing contact wave in the solution of the Riemann problem. The resulting numerical scheme is computationally efficient, robust and positively conservative. The performance of the new solver is evaluated through numerical testing in one and two dimensions.

description: We study a reliable pole selection for the rational approximation of the resolvent of fractional powers of operators in both the finite and infinite dimensional setting. The analysis exploits the representation in terms of hypergeometric functions of the error of the Padé approximation of the fractional power. We provide quantitatively accurate error estimates that can be used fruitfully for practical computations. We present some numerical examples to corroborate the theoretical results. The behavior of the rational Krylov methods based on this theory is also presented.

description: Constraints on cosmological parameters from large-scale structure have traditionally been obtained from two-point statistics. However, non-linear structure formation renders these statistics insufficient in capturing the full information content available, necessitating the measurement of higher-order moments to recover information which would otherwise be lost. We construct quantities based on non-linear and non-local transformations of weakly non-Gaussian fields that Gaussianize the full multivariate distribution at a given order in perturbation theory. Our approach does not require a model of the fields themselves and takes as input only the first few polyspectra, which could be modelled or measured from simulations or data, making our method particularly suited to observables lacking a robust perturbative description such as the weak-lensing shear. We apply our method to simulated density fields, finding a significantly reduced bispectrum and an enhanced correlation with the initial field. We demonstrate that our method reconstructs a large proportion of the linear baryon acoustic oscillations, improving the information content over the raw field by 35%. We apply the transform to toy 21cm intensity maps, showing that our method still performs well in the presence of complications such as redshift-space distortions, beam smoothing, pixel noise, and foreground subtraction. We discuss how this method might provide a route to constructing a perturbative model of the fully non-Gaussian multivariate likelihood function.

description: One of the simplest non-Pisot substitution rules is investigated in its geometric version as a tiling with intervals of natural length as prototiles. Via a detailed renormalisation analysis of the pair correlation functions, we show that the diffraction measure cannot comprise any absolutely continuous component. This implies that the diffraction, apart from a trivial Bragg peak at the origin, is purely singular continuous. En route, we derive various geometric and algebraic properties of the underlying Delone dynamical system, which we expect to be relevant in other such systems as well.

Computation of Surround Modulation Across Layers of the Primate Primary Visual Cortex

description: Primate primary visual cortex (V1) consists of six anatomical layers. There are both heterogeneous and homogeneous functional properties found across layers. Surround modulation (SM) occurs when neuronal responses to stimulation of a neuron's receptive field (RF) is modulated by simultaneous simulation outside of the RF. There are three potential candidates for SM: feedforward (FF) and intra-V1 horizontal (HZ) connections underpin the region nearby RF (near surround), while the modulatory signal arising from distant regions (far surround) are conveyed by feedback (FB) connections from higher visual areas. Also, V1 layers show distinct patterns of FF, HZ, and FB terminations. The goal of my dissertation research was to study 1) the properties of SM across V1 layers, 2) how simple visual stimuli in the RF and surround of a V1 column activate V1 layers, and (3) what specific afferent circuits to and within the V1 column of these stimuli recruit. Using single electrode recordings sampling from all the layers of V1, I found that near SM is more sharply orientation-tuned in the superficial layers (L3B, 4B and 4C?), where there are prominent horizontal connections. However, far SM is more orientation-tuned in L4B, possibly reflecting the orientation organization of feedback connections to this layer. Using laminar recordings, I investigated the temporal dynamics of inputs (local field potentials, LFPs) to each layer when stimulating surround elements. Near surround stimulation simultaneously localized the first inputs in superficial and deep layers with a significant delay in L4C, suggesting both HZ and FB contribute to near SM. Feedback recipient layers (L1/2A and L5/6) received the earliest inputs with far surround stimulation. Measuring the latency of spiking activity while co-stimulating RF and surround, the untuned near SM first emerged in L4C, but, tuned near SM and far SM, emerged outside thalamic recipient layers, suggesting a cortical origin. Finally, I found that brain oscillations in response to stimuli in the surround, mirror the structure of the underlying horizontal and feedback connections. Grating patches positioned on the collinear axis to a cell's preferred orientation, evoke a greater power in different frequency bands of LFP, including alpha, beta, and gamma, compared to orthogonal position in both near and far surround. We propose that horizontal and feedback connections, substrates of near and far surround, are aligned collinearly in the visual field and help generate brain oscillations.
