A Propagation-model Empowered Solution for Blind-Calibration of Sensors
Creators: name: Mishra, Amit Kumar
Publisher: name: arXiv

Subjects: subject: Signal Processing (eess.SP)
subject: FOS: Electrical engineering, electronic engineering, information engineering

description: Calibration of sensors is a major challenge especially in inexpensive sensors and sensors installed in inaccessible locations. The feasibility of calibrating sensors without the need for a standard sensor is called blind calibration. There is very little work in the open literature on totally blind calibration. In this work we model the sensing process as a combination of two processes, viz. propagation of the event through the environment to the sensor and measurement process in the sensor. Based on this, we propose a unique method for calibration in two flavours, viz semi-blind and completely-blind calibration. We show limited results based on simulation showing encouraging results.
Inventions on GUI Aesthetics

description: Aesthetics or "look and feel" is one of the most important features of any graphical user interface. Better aesthetics makes the interface user-friendlier and more popular. Better aesthetics helps the user to understand the meaning of various components and memorize the navigation paths. A better look and feel ultimately makes a GUI more efficient and effective. Various methods are adopted to improve the aesthetics of a GUI, such as, by using colors, using 3D graphics, using pictorial icons, using sound etc. It is important to provide links to all the important features on a desktop or on a quick access panel. But too many icons or buttons sometimes creates confusion. Hence it is important to restrict the temptation of putting everything on the first screen or load the rarely used buttons on the toolbar. One should ensure that the aesthetics of a GUI is not compromising with its accessibility and other important features. This article illustrates some inventions made on GUI aesthetics.

Targeting lung cancer by identifying genes associated with resistance and developing lipid based nanodispersions for the inhalation delivery of therapeutic payloads
Creators: name: Kuzmov, Andriy
Publisher: name: No Publisher Supplied
Year: 2018

description: The efficacy of cancer chemotherapy is limited by the development of resistance and intolerable side effects to conventional chemotherapeutic agents. To help overcome these barriers and improve the treatment of lung cancer, we propose the use of local inhalation delivery of chemotherapeutic drugs in combination of siRNA targeting pump and non-pump cellular resistance mechanism. To deliver the poorly soluble small molecule drug paclitaxel in combination with siRNA, we propose the use of a cationic lipid nanodispersion that can deliver the both therapeutic entities at the same time. To increase the targeting of the drug to cancer cells, LHRH peptide is attached to the delivery system.  To reduce the particle size, improve the stability of the formulation, and improve its biocompatibility, we evaluate the effect of formulation buffer, solid lipids, and surfactant blends on the characteristics of the lipid dispersions. We report the formulation of gefitinib in the optimized lipid nanodispersions. To investigate the role of the PI3K/AKT pathway in the pathogenesis of cancer and development of resistance, we describe the evaluation of the gene expression of three cell lines with varying sensitivities to the EGFR inhibitor gefitinib.

description: A urea-based tripodal receptor L substituted with p-cyanophenyl groups has been studied for halide anions by $^1$H NMR spectroscopy, density functional theory (DFT) calculations and X-ray crystallography. The $^1$H NMR titration studies suggest that the receptor forms a 1:1 complex with an anion, showing the binding trend in the order of fluoride > chloride > bromide > iodide. The interaction of fluoride anion with the receptor was further confirmed by 2D NOESY and $^{19}$F NMR spectroscopy in DMSO-d$_6$. DFT calculations indicate that the internal halide anion is held by six NH...X interactions with L, showing the highest binding energy for the fluoride complex. Structural characterization of the chloride, bromide, and silicon hexafluoride complexes of $[LH^+]$ reveals that the anion is externally located via hydrogen bonding interactions. For the bromide or chloride complex, two anions are bridged with two receptors to form a centrosymmetric dimer, while for the silicon hexafluoride complex, the anion is located within a cage formed by six ligands and two water molecules.

Year: 2022
Subjects: subject: Optimization and Control (math.OC)
subject: FOS: Mathematics

description: In this paper we propose a data-driven distributionally robust Model Predictive Control framework for constrained stochastic systems with unbounded additive disturbances. Recursive feasibility is ensured by optimizing over an linearly interpolated initial state constraint in combination with a simplified affine disturbance feedback policy. We consider a moment-based ambiguity set with data-driven radius for the second moment of the disturbance, where we derive a minimum number of samples in order to ensure user-given confidence bounds on the chance constraints and closed-loop performance. The paper closes with a numerical example, highlighting the performance gain and chance constraint satisfaction based on different sample sizes.

description: Despite the conceptual importance of contextuality in quantum mechanics, there is a hitherto limited number of applications requiring contextuality but not entanglement. Here, we show that for any quantum state and observables of sufficiently small dimensions producing contextuality, there exists a communication task with quantum advantage. Conversely, any quantum advantage in this task admits a proof of contextuality whenever an additional condition holds. We further show that given any set of observables allowing for quantum state-independent contextuality, there exists a class of communication tasks wherein the difference between classical and quantum communication complexities increases as the number of inputs grows. Finally, we show how to convert each of these communication tasks into a semi-device-independent protocol for quantum key distribution.

Bringing it All Together: Integrating Services to Address Homelessness
Creators: name: Turner, Alina
name: Krecsy, Diana
Publisher: name: The School of Public Policy Publications
Year: 2019

description: Homeless-serving systems are striving for greater impact and efficiency amidst austerity. Those with lived experience, governments, funders, and service providers have consistently and increasingly called for enhanced integration across services, organizations, systems, processes and policies as a means of maximizing existing resources. Here, the discourse of integration refers to ways of working better together across diverse internal and external organizational boundaries. At the heart of these efforts lies the assumption that integration is the desired state, an ideal that will result in improved outcomes at individual and population levels.

As actors actively engaged in homeless-serving system planning work, we draw from on-the-ground experiences in Calgary, Alberta to consider how a nuanced understanding of integration can shape the evolution of a systems planning response to homelessness. Our practical experience working in the homeless-serving system on diverse integration initiatives has prompted us to reconsider the evidence and critically probe the implicit link between systems integration efforts and improved individual and population outcomes. In some instances, we have experienced how integration efforts can result in the addition of new layers of complexity to the issue they were created to resolve in the first place. In other cases, integration efforts delivered marginal benefits given the amount of resources used as inputs into planning and implementation. Of course, there are also examples where integration spurs positive impacts at the system and target population levels.

Rather than declaring a course of action, this paper is intended to spur discussion. We are posing questions we continue to grapple with at a praxis level, which may resonate with fellow policy makers, system planner organizations, service providers and researchers. We want to go beyond conventional wisdom to probe the merits of integration as a de facto answer to complex social issues by asking:
• What exactly is integration?
• When and how is integration appropriate?
• What are the pitfalls of integration and how do we manage risks?

Findings suggest that while ventures to enhance integration remain important, they are not and cannot be the panacea to social challenges, including homelessness.  If integration is an appropriate response, we must understand what makes it work, what environment it thrives in, and what success looks like. We maintain that no matter how system integration is implemented or delivered, a central focus on the person served must be maintained, rather than systems themselves.

description: For Lorentzian 2-manifolds $(Σ_1,g_1)$ and $(Σ_2,g_2)$ we consider the two product para-Kähler structures $(G^ε,J,Ω^ε)$ defined on the product four manifold $Σ_1\timesΣ_2$, with $ε=\pm 1$. We show that the metric $G^ε$ is locally conformally flat (resp. Einstein) if and only if the Gauss curvatures $κ_1,κ_2$ of $g_1,g_2$, respectively, are both constants satisfying $κ_1=-εκ_2$ (resp. $κ_1=εκ_2$). We give the conditions on the Gauss curvatures for which every Lagrangian surface with parallel mean curvature vector is the product $γ_1\timesγ_2\subsetΣ_1\timesΣ_2$, where $γ_1$ and $γ_2$ are curves of constant curvature. We study Lagrangian surfaces in the product $d{\mathbb S}^2\times d{\mathbb S}^2$ with non null parallel mean curvature vector and finally, we explore the stability and Hamiltonian stability of certain minimal Lagrangian surfaces and $H$-minimal surfaces.

description: Selecting an object or element is a fundamental operation in any graphic user interface. It is necessary to select an object before doing any operation (such as, dragging, copying, opening, deleting etc.) on that object. The GUI may provide features to select any single object or even multiple objects. The feature of selecting multiple objects can provides tremendous power to the GUI as the user can do complex operations on multiple objects in one go. However, the process of selection is not as simple as it appears to the user of a GUI. The internal logic of a selection mechanism can be very complex in some situations. The article describes some fundamental difficulties associated with the selection mechanism, and illustrates the solutions provided by different inventions selected from US patent database.

description: We carried out an extensive observational study of the Slowly Pulsating B (SPB) star, HD 25558. The ~2000 spectra obtained at different observatories, the ground-based and MOST satellite light curves revealed that this object is a double-lined spectroscopic binary with an orbital period of about 9 years. The observations do not allow the inference of an orbital solution. We determined the physical parameters of the components, and found that both lie within the SPB instability strip. Accordingly, both show line-profile variations due to stellar pulsations. Eleven independent frequencies were identified in the data. All the frequencies were attributed to one of the two components based on Pixel-by-pixel variability analysis of the line profiles. Spectroscopic and photometric mode identification was also performed for the frequencies of both stars. These results suggest that the inclination and rotation of the two components are rather different. The primary is a slow rotator with ~6 d period, seen at ~60 deg inclination, while the secondary rotates fast with ~1.2 d period, and is seen at ~20 inclination. Spectropolarimetric measurements revealed that the secondary component has a magnetic field with at least a few hundred Gauss strength, while no magnetic field can be detected in the primary.

description: Abstract:
General feed forward controllers, conforming to standard control modes, have been derived for an activated sludge process. The analysis indicated that the appropriate controllers are proportional control with measurement of substrate flow rate, and derivative control with measurement of inlet substrate concentration, and manipulation of the rate of return sludge by both controllers.
The performance of these controllers was tested by computer simulation of five dynamic aerator models with and without sludge storage, and with two settling basin models. In all cases significant reduction of the maximum exit substrate concentration was achieved. Additional improvement resulted from the use of sludge storage. As the aerator model became more linear the control results also improved. The first dynamic results were obtained using a perfect steady state settler model, the remainder assumed that the settler dynamics could be represented by a variable time delay. The addition of the settler dynamics caused the control to degrade somewhat.
Finally the generality of the two controllers was proved mathematically for the five biological kinetic models for substrate utilization and bacterial growth.

description: There are considerable interests in automatic stroke lesion segmentation on magnetic resonance (MR) images in the medical imaging field, as stroke is an important cerebrovascular disease. Although deep learning-based models have been proposed for this task, generalizing these models to unseen sites is difficult due to not only the large inter-site discrepancy among different scanners, imaging protocols, and populations, but also the variations in stroke lesion shape, size, and location. To tackle this issue, we introduce a self-adaptive normalization network, termed SAN-Net, to achieve adaptive generalization on unseen sites for stroke lesion segmentation. Motivated by traditional z-score normalization and dynamic network, we devise a masked adaptive instance normalization (MAIN) to minimize inter-site discrepancies, which standardizes input MR images from different sites into a site-unrelated style by dynamically learning affine parameters from the input; \ie, MAIN can affinely transform the intensity values. Then, we leverage a gradient reversal layer to force the U-net encoder to learn site-invariant representation with a site classifier, which further improves the model generalization in conjunction with MAIN. Finally, inspired by the ``pseudosymmetry'' of the human brain, we introduce a simple yet effective data augmentation technique, termed symmetry-inspired data augmentation (SIDA), that can be embedded within SAN-Net to double the sample size while halving memory consumption. Experimental results on the benchmark Anatomical Tracings of Lesions After Stroke (ATLAS) v1.2 dataset, which includes MR images from 9 different sites, demonstrate that under the ``leave-one-site-out'' setting, the proposed SAN-Net outperforms recently published methods in terms of quantitative metrics and qualitative comparisons.

description: Fully integrated supercontinuum sources on-chip are critical to enabling applications such as portable and mechanically-stable medical imaging devices, chemical sensing and LiDAR. However, the low-efficiency of current supercontinuum generation schemes prevent full on-chip integration. In this letter, we present a scheme where the input energy requirements for integrated supercontinuum generation is drastically lowered by orders of magnitude, for bandwidth generation of the order of 500 to 1000 nm. Through sign-alternating the dispersion in a CMOS compatible silicon nitride waveguide, we achieve an efficiency enhancement by factors reaching 3800. We show that the pulse energy requirement for large bandwidth supercontinuum generation at high spectral energy (e.g., 1/e level) is lowered from nanojoules to 6 picojoules. The lowered pulse energy requirements enables that chip-integrated laser sources, such as mode-locked heterogeneously or hybrid integrated diode lasers, can be used as a pump source, enabling fully integrated on-chip high-bandwidth supercontinuum sources.

description: Facial Action Unit (AU) detection is a crucial task for emotion analysis from facial movements. The apparent differences of different subjects sometimes mislead changes brought by AUs, resulting in inaccurate results. However, most of the existing AU detection methods based on deep learning didn't consider the identity information of different subjects. The paper proposes a meta-learning-based cross-subject AU detection model to eliminate the identity-caused differences. Besides, a transformer-based relation learning module is introduced to learn the latent relations of multiple AUs. To be specific, our proposed work is composed of two sub-tasks. The first sub-task is meta-learning-based AU local region representation learning, called MARL, which learns discriminative representation of local AU regions that incorporates the shared information of multiple subjects and eliminates identity-caused differences. The second sub-task uses the local region representation of AU of the first sub-task as input, then adds relationship learning based on the transformer encoder architecture to capture AU relationships. The entire training process is cascaded. Ablation study and visualization show that our MARL can eliminate identity-caused differences, thus obtaining a robust and generalized AU discriminative embedding representation. Our results prove that on the two public datasets BP4D and DISFA, our method is superior to the state-of-the-art technology, and the F1 score is improved by 1.3% and 1.4%, respectively.

description: It is shown here that a subset of the implicit analytical shock solutions discovered by Becker and by Johnson can be inverted, yielding several exact closed-form solutions of the one-dimensional compressible Navier-Stokes equations for an ideal gas. For a constant dynamic viscosity and thermal conductivity, and at particular values of the shock Mach number, the velocity can be expressed in terms of a polynomial root. For a constant kinematic viscosity, independent of Mach number, the velocity can be expressed in terms of a hyperbolic tangent function. The remaining fluid variables are related to the velocity through simple algebraic expressions. The solutions derived here make excellent verification tests for numerical algorithms, since no source terms in the evolution equations are approximated, and the closed-form expressions are straightforward to implement. The solutions are also of some academic interest as they may provide insight into the non-linear character of the Navier-Stokes equations and may stimulate further analytical developments.

description: The 2017 detection of a kilonova coincident with gravitational-wave emission has identified neutron star mergers as the major source of the heaviest elements, and dramatically constrained alternative theories of gravity. Observing a population of such sources has the potential to transform cosmology, nuclear physics, and astrophysics. However, with only one confident multi-messenger detection currently available, modelling the diversity of signals expected from such a population requires improved theoretical understanding. In particular, models which are quick to evaluate, and are calibrated with more detailed multi-physics simulations, are needed to design observational strategies for kilonovae detection, and to obtain rapid-response interpretations of new observations. We use grey-opacity models to construct populations of kilonovae, spanning ejecta parameters predicted by numerical simulations. Our modelling focuses on wavelengths relevant for upcoming optical surveys, such as the Rubin Observatory Legacy Survey of Space and Time (LSST). In these simulations, we implement heating rates that are based on nuclear reaction network calculations. We create a Gaussian-process emulator for kilonova grey opacities, calibrated with detailed radiative transfer simulations. Using recent fits to numerical relativity simulations, we predict how the ejecta parameters from BNS mergers shape the population of kilonovae, accounting for the viewing-angle dependence. Our simulated population of binary neutron star (BNS) mergers produce peak i-band absolute magnitudes $-20 \leq M_i \leq -11$. A comparison with detailed radiative transfer calculations indicates that further improvements are needed to accurately reproduce spectral shapes over the full light curve evolution.

description: I briefly review the Gribov ambiguity of Yang-Mills theory, some of its features and attempts to control it, in particular the Gribov-Zwanziger proposal to restrict the functional integration in the Landau gauge to the Gribov region. This proposal is extended to an arbitrary gauge in such a way as to guarantee BRST invariance. The key insight is that any gauge change in the generating functional can be effected by a suitable field-dependent BRST transformation. I derive a simple analytic formula for the Jacobian of such a transformation, which yields an explicit recipe for the required transformation-parameter functional and allows for the computation of the Gribov horizon functional in any gauge, as I illustrate for the class of R_xi gauges.

description: Continuous-variable optical quantum information processing (CVOQIP), where quantum information is encoded in a traveling wave of light called a flying qubit, is a candidate for a practical quantum computer with high clock frequencies. Homodyne detectors for quadrature-phase amplitude measurements have been the major factor limiting the clock frequency. Here, we developed a real-time amplitude measurement method using a modular optical parametric amplifier (OPA) and a broadband balanced photodiode that is commercially used for coherent wavelength-division multiplexing telecommunication of the fifth-generation mobile communication systems (5G). The OPA amplifies one quadrature-phase component of the quantum-level signal to a loss-tolerant macroscopic level, and acts as a "magic wand," which suppresses the loss after the OPA from 92.4\% to only 0.4\%. When the method was applied to a broadband squeezed vacuum with a center wavelength of 1545.32 nm, we observed 5.2 $\pm$ 0.5 dB of squeezing from DC to 43 GHz without any loss correction. The marriage of CVOQIP and 5G technology arranged by the modular OPA will lead to a paradigm shift from the conventional method of using stationary qubits, where the information is encoded in a standing wave system, to a method using flying qubits for ultra-fast practical quantum computation. This means that quantum computer research will move from the stage of developing machines that execute only specific quantum algorithms to a stage of developing machines that can outperform classical computers in running any algorithm.

description: Windows are used quite frequently in a GUI environment. The greatest advantage of using windows is that each window creates a virtual screen space. Hence, although the physical screen space is limited to a few inches, use of windows can create unlimited screen space to display innumerable items. The use of windows facilitates the user to open and interact with multiple programs or documents simultaneously in different windows. Sometimes a single program may also open multiple windows to display various items. The user can resize the windows and move their location time to time as desired. However, there are several concerns of a window relating to its size, appearance, positioning, color, visibility, resizability etc. For example, the window should have a minimum and a maximum size, dragging and resizing the window should be easy, one window should not be obscured by another window, windows should adjust their size and location in order to match with the changes in the resolution and display environment etc. This article illustrates six patents from US Patent database solving problems relating to displaying and resizing of windows. The inventions include automatic resizing and relocating of windows, alternative modes of displaying windows to accommodate within the limited display area, combining both spatial and temporal methods to resize the window, locking and minimizing windows and making the windows invisible on specific situations.

description: The way that peculiar velocities are often inferred from measurements of distances and redshifts makes an approximation, v_p = cz-H_0 D, that gives significant errors even at relatively low redshifts (overestimates peculiar velocity by ~ 100 km/s at z~0.04). Here we demonstrate where the approximation breaks down, the systematic offset it introduces, and how the exact calculation should be implemented.

description: We solve the problem of equivariant mirror symmetry for O(-3)->P^2 for the (three) cases of one independent equivariant parameter. This gives a decomposition of mirror symmetry for local P^2 into that of three subspaces, each of which may be considered independently. Finally, we give a new interpretation of mirror symmetry for O(k)+O(-2-k)->P^1.

description: We extend the concept of dual unitary quantum gates to quantum lattice models in $2 + 1$ dimensions, by introducing and studying ternary unitary four-particle gates, which are unitary in time and both spatial dimensions. When used as building blocks of lattice models with periodic boundary conditions in time and space (corresponding to infinite temperature states), dynamical correlation functions exhibit a light-ray structure. We also generalize solvable MPS to two spatial dimensions with cylindrical boundary conditions, by showing that the analogous solvable PEPS can be identified with matrix product unitaries. In the resulting tensor network for evaluating equal-time correlation functions, the bulk ternary unitary gates cancel out. We delineate and implement a numerical algorithm for computing such correlations by contracting the remaining tensors.

description: We generalize some properties related to Hilbert series and Lefschetz properties of Milnor algebras of projective hypersurfaces with isolated singularities to the more general case of an almost complete intersection ideal $J$ of dimension one. When the saturation $I$ of $J$ is a complete intersection, we get explicit formulas for a number of related invariants. New examples of hypersurfaces $V:f=0$ in $P^n$ whose Jacobian ideal $J_f$ satisfies this property and with explicit nontrivial Alexander polynomials are given in any dimension. A Lefschetz type property for the graded quotient $I/J$ is proved for $n=2$ and a counterexample due to A. Conca is given for such a property when $n=3$. Two conjectures are also stated in the paper.

description: Federated learning (FL) is a type of collaborative machine learning where participating peers/clients process their data locally, sharing only updates to the collaborative model. This enables to build privacy-aware distributed machine learning models, among others. The goal is the optimization of a statistical model's parameters by minimizing a cost function of a collection of datasets which are stored locally by a set of clients. This process exposes the clients to two issues: leakage of private information and lack of personalization of the model. On the other hand, with the recent advancements in various techniques to analyze data, there is a surge of concern for the privacy violation of the participating clients. To mitigate this, differential privacy and its variants serve as a standard for providing formal privacy guarantees. Often the clients represent very heterogeneous communities and hold data which are very diverse. Therefore, aligned with the recent focus of the FL community to build a framework of personalized models for the users representing their diversity, it is also of utmost importance to protect the clients' sensitive and personal information against potential threats. To address this goal we consider $d$-privacy, also known as metric privacy, which is a variant of local differential privacy, using a a metric-based obfuscation technique that preserves the topological distribution of the original data. To cope with the issue of protecting the privacy of the clients and allowing for personalized model training to enhance the fairness and utility of the system, we propose a method to provide group privacy guarantees exploiting some key properties of $d$-privacy which enables personalized models under the framework of FL. We provide theoretical justifications to the applicability and experimental validation on real datasets to illustrate the working of our method.

description: Let $\mathfrak{p}=(\mathfrak{p}_1,...,\mathfrak{p}_r)$ be a system of $r$ polynomials with integer coefficients of degree $d$ in $n$ variables $\mathbf{x}=(x_1,...,x_n)$. For a given $r$-tuple of integers, say $\mathbf{s}$, a general local to global type statement is shown via classical Hardy-Littlewood type methods which provides sufficient conditions for the solubility of $\mathfrak{p}(\mathbf{x})=\mathbf{s}$ under the condition that each of the $x_i$'s is prime.
PQ-symmetry for a small Dirac neutrino mass, dark radiation and cosmic neutrinos

description: We propose a supersymmetric scenario in which the small Yukawa couplings for the Dirac neutrino mass term are generated by the spontaneous-breaking of Pecci-Quinn symmetry. In this scenario, a right amount of dark matter relic density can be obtained by either right-handed sneutrino or axino LSP, and a sizable amount of axion dark radiation can be obtained. Interestingly, the decay of right-handed sneutrino NLSP to axino LSP is delayed to around the present epoch, and can leave an observable cosmological background of neutrinos at the energy scale of $\mathcal{O}(10-100) {\rm GeV}$.

description: Dieses Lehrvideo zeigt aus der Perspektive einer Übertischkamera den fiktiven informatischen Hochleister Tom bei der Bearbeitung eines schwierigen Färbeproblems. Dabei kann man die fortlaufend von ihm angefertigten Skizzen beobachten und seine Gedankengänge genau verfolgen. Denn dieser Problemlöser arbeitet unter lautem Denken, d. h. er spricht alle seine Gedankengänge laut aus. Man kann zuschauen, wie Tom zunächst die Aufgabe analysiert und die dadurch gewonnenen Erkenntnisse in der anschließenden Problembearbeitung gewinnbringend einsetzt. Der Zuschauer wird dabei aber nicht allein gelassen. An markanten Stellen wird das Video unterbrochen und Toms zurückliegende Aktivitäten mit animierten Bildsequenzen vertiefend erläutert. Schwache Problemlöser können so die in Unterricht oder Vorlesung vermittelten Kenntnisse über informatische Problemlösemethoden vertiefen und deren Anwendung durch einen starken Problemlöser beispielhaft miterleben. Entstanden ist dieses Video aus einer Vergleichsstudie mit starken und schwachen Problemlösern. Die effizienten Methoden der Hochleister wurden didaktisch aufgearbeitet und zu einem modellhaften Problemlöseprozess zusammengesetzt. Der wissenschaftliche Hintergrund des Lehrvideos wird durch eine als Bildergeschichte erzählte Rahmenhandlung verdeutlicht. Bei Erstsemesterstudenten der Informatik, denen dieses Video zur Bewertung vorgespielt wurde, fand dieses Konzept große Zustimmung. Tenor: Unterhaltsam und lehrreich zugleich.
