The exponential increase in the number of wireless devices as well as the limited wireless spectrum, pose significant challenges in the design of future wireless communication systems. Adaptive and re-configurable radios that can change their frequency and mode of operation based on the unused/available wireless spectrum have been proposed to address such challenges. Frequency Agile RF circuits play a key role in realization of such radios.  This webinar focuses on the applications of ferroelectric thin film barium strontium-titanite (BST) for the design of frequency agile radios. BST is a low loss, high dielectric constant field dependent multi-functional material. The electric field dependence of BST has been employed to design tunable RF and microwave devices and components. Another important property of BST is its DC electric field induced piezoelectric or electro-strictive effect. These properties are utilized to design intrinsically switchable film bulk acoustic wave resonators (FBARs) and filters. Switchable ferroelectric based filter banks can significantly reduce size and power consumption of conventional filter banks employed in frequency agile radios. Designs of several BST based adaptive and reconfigurable RF circuits are presented.

description: We aim to determine the fundamental parameters of a sample of B stars with apparent visual magnitudes below 8 in the field-of-view of the CoRoT space mission, from high-resolution spectroscopy. We developed an automatic procedure for the spectroscopic analysis of B-type stars with winds, based on an extensive grid of FASTWIND model atmospheres. We use the equivalent widths and/or the line profile shapes of continuum normalized hydrogen, helium and silicon line profiles to determine the fundamental properties of these stars in an automated way. After thorough tests, both on synthetic datasets and on very high-quality, high-resolution spectra of B stars for which we already had accurate values of their physical properties from alternative analyses, we applied our method to 66 B-type stars contained in the ground-based archive of the CoRoT space mission. We discuss the statistical properties of the sample and compare them with those predicted by evolutionary models of B stars. Our spectroscopic results provide a valuable starting point for any future seismic modelling of the stars, should they be observed by CoRoT.

description: We extend Mulliken's theory of ground state charge transfer in a donor-acceptor complex to excited state charge transfer between pairs of identical $π$-conjugated oligomers, one of which is in the optically excited state and the other in the ground state, leading to the formation of a charge-transfer exciton. Within our theory, optical absorptions from the charge-transfer exciton should include a low energy intermolecular charge-transfer excitation, as well as distinct intramolecular excitations from both the neutral delocalized exciton component and the Coulombically bound polaron-pair component of the charge-transfer exciton. We report high order configuration-interaction calculations for pairs of oligomers of poly-paraphenylenevinylene (PPV) that go beyond our previous single configuration-interaction calculation and find all five excited state absorptions predicted using heuristic arguments based on the Mulliken concept. Our calculated excited state absorption spectrum exhibits strong qualitative agreement with the complete wavelength-dependent ultrafast photoinduced absorption in films of PPV derivatives, suggesting that a significant fraction of the photoinduced absorption here is from the charge-transfer exciton. We make detailed comparisons to experiments, and a testable experimental prediction.

The method is based on PCAC and relates the reaction $\textbf{boson} + \textbf{nucleus} \to \textbf{pion} + \textbf{nucleus}$ to elastic pion-nucleus scattering. Estimates for the expected rates and distributions in neutrino reactions are presented with the help of hadronic data. The absolute rates are significantly smaller than the older estimates which brings theory in agreement with the neutral current measurements and the bounds in charged current reactions.

Such quantum-secure PRPs have found numerous applications in cryptography and complexity theory. Our construction combines a quantum-secure pseudorandom function together with constructions of classical format preserving encryption. By combining known results, we show how to construct quantum-secure PRP in this model whose security relies only on the existence of one-way functions.
Security Defender Advantages Via Economically Rational Adversary Modeling

description: Cyber attacks are an increasing threat to victims ranging from individuals to businesses and nation-states. Underpinning these attacks is an ecosystem of adversaries that compete with each other in profitable nefarious activities such as advertising illegal pharmacies, manipulatingbusiness and product reviews, or engaging in illegal financial activities. Preventing these attacks in general is intractable as it involves solving problems such as creating perfectly secure software, authenticating product reviews, and verifying the intentions of financial market participants. Inthis work we approach these problems through the lens of economic rationality and postulate that understanding the economics of the attacker unlocks empirically effective solutions that make attacks unattractive or impractical rather than impossible.

Motion Planning for Autonomous Vehicles in Urban Scenarios: A Sequential Optimization Approach
Creators: name: Xu, Wenda
Publisher: name: Carnegie Mellon University

Subjects: subject: 90602 Control Systems, Robotics and Automation
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Motion planning is essential for an autonomous vehicle to perform safe and humanlike driving behaviors, especially in highly dynamic scenarios such as dense urban and highway environments. The motion planning problem is challenging in that it needs to handle static and dynamic obstacles and obey kinematic and dynamic constraints as well as traffic rules. In this work, we propose an efficient hierarchicalmotion planning approach based on path-speed decomposition. We find plan a path to avoid static obstacles, then generate a speed profile along the path to interactwith dynamic obstacles. The first sub-problem is path planning with static obstacles. It can be viewed as non-convex constrained nonlinear optimization, which requires a good enough initial guess to start and is often sensitive to algorithm parameters. We formulate it as convex spline optimization. The convexity of the formulated problem makes it able to be solved fast and reliably, while guaranteeing a global optimum. We then reorganize the constrained spline optimization into a recurrent formulation, which further reduces the computational time to be linear in the optimization horizon size. The second sub-problem is the minimum-time speed planning problem over a fixed path with dynamic obstacle constraints and point-wise speed and acceleration constraints. The contributions of our speed planning method are three-fold. First, we formulate the speed planning as an iterative convex optimization problembased on space discretization. Our formulation allows imposing dynamic obstacle constraints and point-wise speed and acceleration constraints simultaneously. Second,we propose a modified vertical cell decomposition method to handle dynamic obstacles. It divides the freespace into channels, where each channel represents a homotopy of free paths and defines convex constraints for dynamic obstacles. Third, we demonstrate significant improvement over previous work on speed planning for typical driving scenarios such as following, merging, and crossing.

description: In this thesis we explore a multilinear duality principle of Carbery–Hänninen–Valdimarsson for multilinear geometric inequalities arising in Harmonic Analysis. In Chapter 2, we give a brief survey of how this theory manifests for a number of classical inequalities. The material in Chapter 2 is mostly expository except for two original results: Theorem 2.17, which gives an explicit factorisation of the classical Young convolution inequality on R, and Proposition 2.10, establishing the equivalence of two natural formulations of an affine-invariant Finner inequality. The material in Section 2.3 is also new. In Chapter 3, we discuss a certain structural duality between instances of the geometric Brascamp–Lieb inequality, and briefly explore how this manifests on the level of factorisations. Most of the material presented in this chapter is not original research. However, the connection between Lemma 3.2 and Proposition 3.7 in the setting of the geometric Brascamp–Lieb inequality is new. In particular, we give a new proof for a special case of Proposition 3.7, which only relies on the sharpness of the geometric Brascamp–Lieb inequality along with a generalised version of Lemma 3.2. In Chapter 4 we study factorisations due to Guth for the endpoint multilinear Kakeya inequality, and factorisations due to Zhang for a corresponding generalisation to kj -planes. In particular, we uncover interesting connections to classical notions of convex geometry. The main contributions of this chapter stem from the statements and proofs of Theorems 4.7 and 4.13. In particular, these two geometric observations allow us to translate Guth’s visibility theorem, stated below as Theorem 4.33, into statements about convex bodies, which lead us to the formulation of Theorems 4.8 and 4.14. In Chapter 5 we study a sequence of generalised versions of Guth’s directed volume - see Definition 4.3. The main contribution of this chapter is Theorem 5.1, giving a sharp chain of inequalities for such geometric quantities. Furthermore, we conjecture restricted inequalities of the same type, which are optimal for boundaries of parallelotopes and related to a vector-valued generalisation of the classical Maclaurin inequality. In Chapter 6, we prove various special cases of this vector-valued variant of the Maclaurin inequality, and highlight connections to open problems in convex geometry.
Hierarchical analytical approach to universal spectral correlations in Brownian Quantum Chaos

description: We develop an analytical approach to the spectral form factor and out-of-time ordered correlators in zero-dimensional Brownian models of quantum chaos. The approach expresses these spectral correlations as part of a closed hierarchy of differential equations that can be formulated for all system sizes and in each of the three standard symmetry classes (unitary, orthogonal, and symplectic, as determined by the presence and nature of time-reversal symmetry). The hierarchy applies exactly, and in the same form, to Dyson's Brownian motion and all systems with stochastically emerging basis invariance, where the model-dependent information is subsumed in a single dynamical time scale whose explicit form we also establish. We further verify this universality numerically for the Brownian Sachdev-Ye-Kitaev model, for which we find perfect agreement with the analytical predictions of the symmetry class determined by the number of fermions. This results in a complete analytical description of the spectral correlations and allows us to identify which correlations are universal in a large class of models.

Superconducting triplet pairings and anisotropic tunneling-magnetoresistance effects in ferromagnet/superconductor/ferromagnet double-barrier junctions

Publisher: name: Universität Regensburg
Year: 2021
Subjects: subject: 530 Physik

description: Ferromagnetic spin valves offer the key building blocks to integrate giant- and tunneling-magnetoresistance effects into spintronics devices. Starting from a generalized Blonder--Tinkham--Klapwijk approach, we theoretically investigate the impact of interfacial Rashba and Dresselhaus spin-orbit couplings on the tunneling conductance, and thereby the tunneling-magnetoresistance characteristics, of ferromagnet/superconductor/ferromagnet spin-valve junctions embedding thin superconducting spacers between the either parallel or antiparallel magnetized ferromagnets. We focus on the unique interplay between usual electron tunnelings -- that fully determine the tunneling magnetoresistance in the normal-conducting state -- and the peculiar Andreev reflections in the superconducting state. In the presence of interfacial spin-orbit couplings, special attention needs to be paid to the spin-flip ("unconventional") Andreev-reflection process that is expected to induce superconducting triplet correlations in proximitized regions. As a transport signature of these triplet pairings, we detect conductance double-peaks around the singlet-gap energy, reflecting the competition between the singlet and the newly emerging triplet gap. We thoroughly analyze the Andreev reflections' role in connection with superconducting tunneling-magnetoresistance phenomena, and eventually unravel huge conductance and tunneling-magnetoresistance magnetoanisotropies -- easily exceeding their normal-state counterparts by several orders of magnitude -- as another experimentally accessible fingerprint of unconventional Andreev reflections. Our results provide an important contribution to establish superconducting magnetic spin valves as an essential ingredient for future superconducting-spintronics concepts.
Monolithic Microwave Integrated Circuits: Design Strategies for First-Time Success Slides

MTT Webinar Slides
The ever expanding need for higher data rates is accelerating the development of fifth generation (5G) cellular systems, mm-wave backhaul microwave links, and ultra-wide band highly integrated circuits. Concurrently, commercial and military applications are seeking the replacement of discrete hybrid solutions with monolithic microwave integrated circuits (MMIC) to increase performance and reduce size, weight, power, and cost (so called SWaP-C). The development cycle of MMICs in III-V semiconductors (e.g. GaAs, GaN, and InP) is costly and time consuming. However, a successful design can dramatically reduce the cost/unit, increase performance, and extend the reliability of the entire system. In this webinar, we will review the cost drivers in the MMIC development cycle, the expected cost/unit, critical active/passive modeling techniques, estimation of MMIC lifetime, and instability suppression.
Sidelobe Control in Collaborative Beamforming via Node Selection

description: Collaborative beamforming (CB) is a power efficient method for data communications in wireless sensor networks (WSNs) which aims at increasing the transmission range in the network by radiating the power from a cluster of sensor nodes in the directions of the intended base station(s) or access point(s) (BSs/APs). The CB average beampattern expresses a deterministic behavior and can be used for characterizing/controling the transmission at intended direction(s), since the mainlobe of the CB beampattern is independent on the particular random node locations. However, the CB for a cluster formed by a limited number of collaborative nodes results in a sample beampattern with sidelobes that severely depend on the particular node locations. High level sidelobes can cause unacceptable interference when they occur at directions of unintended BSs/APs. Therefore, sidelobe control in CB has a potential to increase the network capacity and wireless channel availability by decreasing the interference. Traditional sidelobe control techniques are proposed for centralized antenna arrays and, therefore, are not suitable for WSNs. In this paper, we show that distributed, scalable, and low-complexity sidelobe control techniques suitable for CB in WSNs can be developed based on node selection technique which make use of the randomness of the node locations. A node selection algorithm with low-rate feedback is developed to search over different node combinations. The performance of the proposed algorithm is analyzed in terms of the average number of trials required to select the collaborative nodes and the resulting interference. Our simulation results approve the theoretical analysis and show that the interference is significantly reduced when node selection is used with CB.

description: Electrophysiological measurements of neurons recorded individually, collectively, and across brain regions simultaneously have been advancing the study of biophysical properties of individual neurons, information encoding and decoding, and interactions between neuronal ensembles. The recordings are composed of sequences of action potentials, usually referred to as spike trains, which carry signals of neural activity but they are contaminated with ubiquitous Poisson-type noise and the patterns vary from neuron to neuron, time to time, and trial to trial. The discreteness and randomness of the data make point process a suitable tool for understanding the neural signals represented by spike train data. This thesis provides four applications of point process modeling to spiking neurons. The first project addresses stability of fitted point process regression models. In the second project, we aim to bridge biophysical modeling and statistical modeling by describing how ion channel conductance can affect spike train patterns. The third project studies the covariation of time-dependent population firing rate features among interacting brain regions. The fourth project focuses on the inter-spike dependency between brain areas with weak coupling effects.

description: This paper examines relationship of unemployment rates with other macroeconomic aggregates in Bangladesh over 1991-2019 using robust econometric analyses. It sheds a
light on the fact that GDP growth rate, inflation, and foreign direct investment flows have statistically significant impacts on unemployment rate both in short-run and long-run.
More specifically, the paper documents that unemployment rate, GDP growth rate, inflation rate and foreign direct investment flows are co-integrated in long-run at 5%
significance level. Using Vector Error Correction analysis, the paper finds that co-integrated series converge it
their long-run equilibrium at a speed of 17.24% per annum at 1% significance level. In case short-run, the study finds that a unit increase in GDP growth rate decreases unemployment by approximately 0.0159 units in short-run at 1% statistically significance level. Likewise, a unit increase in inflation rate will lead approximately 0.004 units drop in unemployment rate at 10% significance level. Plus, it also observes that a unit in Foreign Direct Investment flows causes 0.005 units decrease in unemployment rate in short-run at 5% significance level.
Terahertz Systems in Silicon: Overcoming Device Level Limitations for System Level Functionalities Slides

MTT Webinar Video
The last decade has seen tremendous advances in terahertz (THz) science and technology across a wide range of substrates from solid-state and photonic devices to 2D and nano-materials. In spite of the progress, the field can greatly benefit from low-cost, integrated, room-temperature technology that can potentially bring transformative changes for a wide range of applications in sensing, imaging and communications, not currently accessible due to cost, size and power limitations. Silicon-based integrated circuit technology with its extremely high levels of integration provides a potential platform, but conventional design methodologies need to be re-explored for efficient THz chip-scale systems. This search is partially facilitated by two important factors that have opened up a new paradigm and design space.
Firstly, device scaling has pushed cut-off frequencies of silicon-based integrated devices to reach sub-THz and THz frequencies. This has allowed us to generate, process and receive THz signals in a substrate that supports integration of a billion active devices. Simultaneously, at these frequencies, the chip dimension has become several times larger than the wavelength, which theoretically allows efficient radiating properties of integrated electromagnetic (EM) interfaces. These together have created a unique opportunity for fundamentally different architectures, methodologies and a new class of active, reconfigurable multi-functional THz EM structures for signal generation and reception that can enable fully integrated, high-performance THz systems-on-chip.
In this webinar, I will highlight some of the seminal advances in THz chip-scale systems in silicon in the last decade, challenges ahead and comment on future opportunities and applications for integrated THz systems.

RFID technology provides a foundation, an enabling technology towards the realization of ‘zero-power’ wireless sensors and implementing the Internet-of-Things (IoT) and machine-to-machine (M2M) communication. Interest in RFID technology is further enhanced by its fundamental capability for wireless powering of devices, allowing for battery-less operation. The presentation begins with an overview of ambient energy availability and energy harvesting technology challenges for low power circuits and sensors. Design challenges and novel technologies and materials, such as paper, textiles, and inkjet/3D printing are highlighted. Special focus is placed on electromagnetic energy transfer and harvesting for range maximization of passive RFID systems. Rectenna design and optimization under different operating conditions and in different operating frequencies from HF to millimeter waves is addressed. Multiple technology harvesters leading to the development of energy harvesting assisted RFIDs are discussed. Low profile and conformal solar antennas and solar–electromagnetic harvesters including examples implemented on paper and textile substrates are presented. The integration of an antenna with a thermo-electric generator is demonstrated. Waveform optimization in wireless power transfer is addressed, and the ability to improve the RF-DC power conversion efficiency of electromagnetic energy harvesting devices by tailoring the characteristics of the transmitted signals is discussed. The last part of the talk presents application examples including wireless sensors powered from solar and electromagnetic energy harvesting, millimeter wave back-scattering, solar energy harvesting for RFID tags and sensors based on ambient backscattering.

description: We address the question of whether integrable models allow for PT-symmetric deformations which preserve their intgrability. For this purpose we carry out the Painleve test for PT-symmetric deformations of Burgers and the Korteweg-De Vries equation. We find that the former equation allows for infinitely many deformations which pass the Painleve test. For a specific deformation we prove the convergence of the Painleve expansion and thus establish the Painleve property for these models, which are therefore thought to be integrable. The Korteweg-De Vries equation does not allow for deformations which pass the Painleve test in complete generality, but we are able to construct a defective Painleve expansion.

Terahertz Imaging for Margin Assessment of Excised Breast Cancer Tumors Slides

MTT Webinar Slides
Breast cancer is a serious disease with almost one out of eight women in the U.S. expecting a diagnosis of breast cancer in her lifetime. The American Cancer Society (ACS) is the leader in the fight to end breast cancer with investing more in breast cancer research than any other cancer type to detect, prevent, treat, and cure the disease. This research is focused on investigating the capability of terahertz (THz) imaging and spectroscopy to differentiate between different types of tumor tissues in lumpectomy surgery. Breast Conserving Surgery (BCS), lumpectomy, reduces breast disfigurement compared with radical mastectomy. However, the margins of excised tumor tissue need to be analyzed by pathologists to judge if there remain any traces of cancerous tissue. This can take several days and in the case of positive margin detection a second surgery is needed to remove more tissue. Unfortunately, clinical studies indicated that in around 20-40% of cases excised malignant breast tumors contain positive margins. THz technology offers several favorable features, including high sub-millimeter resolution, minimal scattering, and sensitivity to water content. Experimental data in the literature demonstrated image contrast enhancement when using THz waves compared with near-infrared and optical radiation. The novelty of this research lies in imaging three dimensional (3D) tumors instead of processed two dimensional (2D) sections. By using the whole excised tumor tissues, we demonstrate that THz imaging has a potential to be incorporated directly in the operating room for real time margin assessment. This research demonstrates THz transmission and reflection imaging of freshly excised and formalin-fixed, paraffin-embedded breast cancer tumors. THz imaging is shown a capability in defining the three-dimensional boundaries of tumors embedded in paraffin blocks. This procedure produces cross-section images of the tumor borders at any depth and enables direct correlation with histopathology sections. Tumors obtained from mice models and human breast are investigated. Unsupervised classifier is implemented to evaluate the THz image correlation with pathology. This research is a collaboration between electrical engineering, biomedical engineering and pathology at the University of Arkansas and Oklahoma State University.

description: The X-Ray Telescope (XRT) on the Japanese/USA/UK {\it Hinode (Solar-B)} spacecraft has detected emission from a quiescent active region core that is consistent with nanoflare heating. The fluxes from 10 broadband X-ray filters and filter combinations were used to constructed Differential Emission Measure (DEM) curves. In addition to the expected active region peak at Log T = 6.3-6.5, we find a high-temperature component with significant emission measure at Log T $>$ 7.0. This emission measure is weak compared to the main peak -- the DEM is down by almost three orders of magnitude -- which accounts of the fact that it has not been observed with earlier instruments. It is also consistent with spectra of quiescent active regions: no Fe XIX lines are observed in a CHIANTI synthetic spectrum generated using the XRT DEM distribution. The DEM result is successfully reproduced with a simple two-component nanoflare model.

description: This paper reports the compatibility of heterostructure-based spin qubit devices with industrial CMOS technology. It features Si/Si-Ge quantum dot devices fabricated using Infineon's 200 mm production line within a restricted thermal budget. The devices exhibit state-of-the-art charge sensing, charge noise and valley splitting characteristics, showing that industrial fabrication is not harming the heterostructure quality. These measured parameters are all correlated to spin qubit coherence and qubit gate fidelity. We describe the single electron device layout, design and its fabrication process using electron beam lithography. The incorporated standard 90 nm back-end of line flow for gate-layer independent contacting and wiring can be scaled up to multiple wiring layers for scalable quantum computing architectures. In addition, we present millikelvin characterization results. Our work exemplifies the potential of industrial fabrication methods to harness the inherent CMOS-compatibility of the Si/Si-Ge material system, despite being restricted to a reduced thermal budget. It paves the way for advanced quantum processor architectures with high yield and device quality.

description: We present local biplots, an extension of the classic principal component biplot to multidimensional scaling. Noticing that principal component biplots have an interpretation as the Jacobian of a map from data space to the principal subspace, we define local biplots as the Jacobian of the analogous map for multidimensional scaling. In the process, we show a close relationship between our local biplot axes, generalized Euclidean distances, and generalized principal components. In simulations and real data we show how local biplots can shed light on what variables or combinations of variables are important for the low-dimensional embedding provided by multidimensional scaling. They give particular insight into a class of phylogenetically-informed distances commonly used in the analysis of microbiome data, showing that different variants of these distances can be interpreted as implicitly smoothing the data along the phylogenetic tree and that the extent of this smoothing is variable.

Gerbils fostered to rat mothers : effects on adult behavior

description: At 72 hrs after birth gerbil litters were divided and half the pups fostered to lactating mother rats whose own pups were removed. Remaining pups were returned to their natural mothers. Rat-reared gerbils had a higher mortality rate than control gerbils but weighed more at weaning. At 60 days control gerbils weighed more and at 100 days there was no difference in weight. When tested in the open-field from Day 128 to Day 135, rat-reared gerbils were found to locomote and rear less than control subjects. There was no difference in defecation or in the tendency to enter the central squares as a result of fostering. The paper shredding and territorial marking activity of the subjects were also measured but no clear cut effects of fostering emerged on these tests. The results were discussed in relation to those obtained with rat-reared mice and it was suggested that species differences in maternal behavior, especially handling and retrieving of pups, may be the crucial factor responsible for fostering effects.

description: We present a construction of an entropy-preserving equivariant surjective map from the $d$-dimensional critical sandpile model to a certain closed, shift-invariant subgroup of $\mathbb{T}^{\mathbb{Z}^d}$ (the `harmonic model'). A similar map is constructed for the dissipative abelian sandpile model and is used to prove uniqueness and the Bernoulli property of the measure of maximal entropy for that model.
