An ATM-based interworking architecture for wireless personal communications
Creators: name: Wong, Terrence Sui Wing
Publisher: name: University of British Columbia
Year: 2009

description: The growing demand for mobile communication services as well as technological advances drive the new generation of Personal Communication Networks (PCNs). New or modified networks and communication protocols are required to support associated Personal communication Services (PCS). An ATM-based architecture has been proposed to support future PCS. The network would provide improved PCS performance for applications such as hand-off and call set up. CDMA technology is assumed as the air interface, with a bandwidth in each cell site of 2.5 MHz and a sectorization antenna with 3 sectors/cell. The PCS radio cell coverage size varies depending on geographic location; radii of 275 m and 981 m are proposed for microcells in metropolitan and urban areas, respectively. The topology of the proposed network is a star configuration which connects the base stations (BS) to the mobile switching centre (MSC). The proposed network which interconnects 16 switching centers can support up to 3.0 million potential PCS users with a coverage of 600 Km2 in metropolitan area. Strategies such as fast hand-off routing and signalling schemes are presented based on the virtual connection tree concept. Radio cells with a 50 percent overlapping area for improving hand-off performance are considered. Radio cell radii are calculated in different environments with various market penetrations. Cell site overload probability for voice and data users within a connection tree region is studied. Network performance in terms of end-to-end delay, cell delay variation, and buffer occupancy are investigated in depth.

description: The aim of this paper is twofold. On one hand, it presents a multi-dimensional Markovian state transition model characterizing the behavior at the Medium Access Control (MAC) layer by including transmission states that account for packet transmission failures due to errors caused by propagation through the channel, along with a state characterizing the system when there are no packets to be transmitted in the queue of a station (to model non-saturated traffic conditions). On the other hand, it provides a throughput analysis of the IEEE 802.11 protocol at the data link layer in both saturated and non-saturated traffic conditions taking into account the impact of both transmission channel and multirate transmission in Rayleigh fading environment. Simulation results closely match the theoretical derivations confirming the effectiveness of the proposed model.

description: We investigate the prospects for neutrinoless double beta decay, texture zeros and equalities between neutrino mass matrix elements in scenarios with vanishing determinant mass matrices for vanishing and finite $θ_{13}$ mixing angle in normal and inverse mass hierarchies. For normal hierarchy and both zero and finite $θ_{13}$ it is found that neutrinoless double beta decay cannot be observed by any of the present or next generation experiments, while for inverse hierarchy it is, on the contrary, accessible to experiments. Regarding texture zeros and equalities between mass matrix elements, we find that in both normal and inverse hierarchies with $θ_{13}=0$ no texture zeros nor any such equalities can exist apart from the obvious ones. For $θ_{13}\ne 0$ some texture zeros become possible. In normal hierarchy two texture zeros occur if $8.1\times 10^{-2}\leq |sin θ_{13}|\leq 9.1\times 10^{-2}$ while in inverse hierarchy three are possible, one with $|sin θ_{13}|\geq 7\times 10^{-3}$ and two others with $|sin θ_{13}|\geq 0.18$. All equalities between mass matrix elements are impossible with $θ_{13}\ne 0$.

description: Radial imaging techniques, such as projection-reconstruction (PR), are used in magnetic resonance imaging (MRI) for dynamic imaging, angiography, and short-imaging. They are robust to flow and motion, have diffuse aliasing patterns, and support short readouts and echo times. One drawback is that standard implementations do not support anisotropic field-of-view (FOV) shapes, which are used to match the imaging parameters to the object or region-of-interest. A set of fast, simple algorithms for 2-D and 3-D PR, and 3-D cones acquisitions are introduced that match the sampling density in frequency space to the desired FOV shape. Tailoring the acquisitions allows for reduction of aliasing artifacts in undersampled applications or scan time reductions without introducing aliasing in fully-sampled applications. It also makes possible new radial imaging applications that were previously unsuitable, such as imaging elongated regions or thin slabs. 2-D PR longitudinal leg images and thin-slab, single breath-hold 3-D PR abdomen images, both with isotropic resolution, demonstrate these new possibilities. No scan time to volume efficiency is lost by using anisotropic FOVs. The acquisition trajectories can be computed on a scan by scan basis.

description: In recent years, privacy-preserving machine learning algorithms have attracted increasing attention because of their important applications in many scientific fields. However, in the literature, most privacy-preserving algorithms demand learning objectives to be strongly convex and Lipschitz smooth, which thus cannot cover a wide class of robust loss functions (e.g., quantile/least absolute loss). In this work, we aim to develop a fast privacy-preserving learning solution for a sparse robust regression problem. Our learning loss consists of a robust least absolute loss and an $\ell_1$ sparse penalty term. To fast solve the non-smooth loss under a given privacy budget, we develop a Fast Robust And Privacy-Preserving Estimation (FRAPPE) algorithm for least absolute deviation regression. Our algorithm achieves a fast estimation by reformulating the sparse LAD problem as a penalized least square estimation problem and adopts a three-stage noise injection to guarantee the $(ε,δ)$-differential privacy. We show that our algorithm can achieve better privacy and statistical accuracy trade-off compared with the state-of-the-art privacy-preserving regression algorithms. In the end, we conduct experiments to verify the efficiency of our proposed FRAPPE algorithm.

HD259431 now shows a double Halpha profile with the red component stronger than the blue component, while in the earlier observations the blue peak was higher than the red peak. Finally, the last Halpha profile of LkHalpha215 is very similar to that obtained by Finkenzeller et al.

description: Recent observational studies of rocky exoplanets with Kepler and TESS missions suggest that many rocky exoplanets are detected in the habitable zone around magnetically active solar-like stars. These stars are efficient generators of ionizing radiation in the form of X-ray and Extreme UV (EUV) flux (collectively known as XUV), wind mass loss and eruptive events. While these outputs are the critical factors affecting the planetary atmospheres via initiation of atmospheric erosion and their impact on atmospheric chemistry, they are poorly known. Here, we present the results of data driven three-dimensional magnetohydrodynamic modeling of the global corona of a young (650 Myr) solar-like star, k1 Ceti, using observational data inputs at two epochs separated by 11 months. Over the course of 11 months, the global corona had undergone drastic transition from a simple dipole to a tilted multipole global magnetic field, which provides favorable conditions for formation of Corotating Interaction Regions (CIRs) and associated strong shocks, the source of energetic protons and the impact of their dynamic pressure on exoplanetary magnetospheres. The modeled XUV and wind fluxes provide the framework for evaluating their impact on atmospheric loss from the early terrestrial exoplanets that will be tested in the upcoming multi-observatory multi-epoch observations of evolving young solar-like stars.

description: Aesthetic quality assessment (AQA) is a challenging task due to complex aesthetic factors. Currently, it is common to conduct AQA using deep neural networks that require fixed-size inputs. Existing methods mainly transform images by resizing, cropping, and padding or employ adaptive pooling to alternately capture the aesthetic features from fixed-size inputs. However, these transformations potentially damage aesthetic features. To address this issue, we propose a simple but effective method to accomplish full-resolution image AQA by combining image padding with region of image (RoM) pooling. Padding turns inputs into the same size. RoM pooling pools image features and discards extra padded features to eliminate the side effects of padding. In addition, the image aspect ratios are encoded and fused with visual features to remedy the shape information loss of RoM pooling. Furthermore, we observe that the same image may receive different aesthetic evaluations under different themes, which we call theme criterion bias. Hence, a theme-aware model that uses theme information to guide model predictions is proposed. Finally, we design an attention-based feature fusion module to effectively utilize both the shape and theme information. Extensive experiments prove the effectiveness of the proposed method over state-of-the-art methods.

description: Excited state electron and hole transfer underpin fundamental steps in processes such as exciton dissociation at photovoltaic heterojunctions, photoinduced charge transfer at electrodes, and electron transfer in photosynthetic reaction centers. Diabatic states corresponding to charge or excitation localized species, such as locally excited and charge transfer states, provide a physically intuitive framework to simulate and understand these processes. However, obtaining accurate diabatic states and their couplings from adiabatic electronic states generally leads to inaccurate results when combined with low-tier electronic structure methods, such as time dependent density functional theory (TDDFT), and exorbitant computational cost when combined with high-level wavefunction-based methods. Here we introduce a DFT-based diabatization scheme, Δ-ALMO(MSDFT2), which directly constructs the diabatic states using absolutely localized molecular orbitals (ALMOs). We demonstrate that our method, which combines ALMO calculations with the ΔSCF technique to construct electronically excited diabatic states and obtains their couplings with charge-transfer states using our MSDFT2 scheme, gives accurate results for excited state electron and hole transfer in both charged and uncharged systems that underlie DNA repair, charge separation in donor-acceptor dyads, chromophore-to-solvent electron transfer, and singlet fission. This framework for the accurate and efficient construction of excited state diabats and evaluation of their couplings directly from DFT thus offers a route to simulate and elucidate photoinduced electron and hole transfer in large disordered systems, such as those encountered in the condensed phase.

description: Strain engineering has quickly emerged as a viable option to modify the electronic, optical and magnetic properties of 2D materials. However, it remains challenging to arbitrarily control the strain. Here we show that by creating atomically-flat surface nanostructures in hexagonal boron nitride, we achieve an arbitrary on-chip control of both the strain distribution and magnitude on high-quality molybdenum disulfide. The phonon and exciton emissions are shown to vary in accordance with our strain field designs, enabling us to write and draw any photoluminescence color image in a single chip. Moreover, our strain engineering offers a powerful means to significantly and controllably alter the strengths and energies of interlayer excitons at room temperature. This method can be easily extended to other material systems and offers a promise for functional excitonic devices.

Exact $\mathcal{N}$-point function mapping between pairs of experiments with Markovian open quantum systems

Year: 2020
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We formulate an exact spacetime mapping between the $\mathcal{N}$-point correlation functions of two different experiments with open quantum gases. Our formalism extends a quantum-field mapping result for closed systems [Phys. Rev. A \textbf{94}, 043628 (2016)] to the general case of open quantum systems with Markovian property. For this, we consider an open many-body system consisting of a $D$-dimensional quantum gas of bosons or fermions that interacts with a bath under Born-Markov approximation and evolves according to a Lindblad master equation in a regime of loss or gain. Invoking the independence of expectation values on pictures of quantum mechanics and using the quantum fields that describe the gas dynamics, we derive the Heisenberg evolution of any arbitrary $\mathcal{N}$-point function of the system in the regime when the Lindblad generators feature a loss or a gain. Our quantum field mapping for closed quantum systems is rewritten in the Schrödinger picture and then extended to open quantum systems by relating onto each other two different evolutions of the $\mathcal{N}$-point functions of the open quantum system. As a concrete example of the mapping, we consider the mean-field dynamics of a simple dissipative quantum system that consists of a one-dimensional Bose-Einstein condensate being locally bombarded by a dissipating beam of electrons in both cases when the beam amplitude or the waist is steady and modulated.

Strong lensing time delay: a new way of measuring cosmic shear
Creators: name: Lieu, Richard
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The phenomenon of cosmic shear, or distortion of images of distant sources unaccompanied by magnification, is an effective way of probing the content and state of the foreground Universe, because light rays do not have to pass through mass structures in order to be sheared. It is shown that the delay in the arrival times between two simultaneously emitted photons that appear to be arriving from a pair of images of a strongly lensed cosmological source contains not only information about the Hubble constant, but also the long range gravitational effect of galactic scale mass clumps located away from the light paths in question. This is therefore also a method of detecting shear. Data on time delays among a sample of strongly lensed sources can provide crucial information about whether extra dynamics beyond gravity and dark energy are responsible for the global flatness of space. If the standard $ΛCDM$ model is correct, there should be a large dispersion in the value of $H_0$ as inferred from the delay data by (the usual procedure of) ignoring the effect of all other mass clumps except the strong lens itself. The fact that there has not been any report of a significant deviation from the $h =$ 0.7 mark during any of the $H_0$ determinations by this technique may already be pointing to the absence of the random effect discussed here.

description: We present a Machine Learning based approach to the cross section and asymmetries for deeply virtual Compton scattering from an unpolarized proton target using both an unpolarized and polarized electron beam. Machine learning methods are needed to study and eventually interpret the outcome of deeply virtual exclusive experiments since these reactions are characterized by a complex final state with a larger number of kinematic variables and observables, exponentially increasing the difficulty of quantitative analyses. Our deep neural network (FemtoNet) uncovers emergent features in the data and learns an accurate approximation of the cross section that outperforms standard baselines. FemtoNet reveals that the predictions in the unpolarized case systematically show a smaller relative median error than the polarized that can be ascribed to the presence of the Bethe Heitler process. It also suggests that the $t$ dependence can be more easily extrapolated than for the other variables, namely the skewness, $ξ$ and four-momentum transfer, $Q^2$. Our approach is fully scalable and will be capable of handling larger data sets as they are released from future experiments.

description: This technical memorandum provides a comprehensive summary of 37 killer whale entanglement reports in Alaska from 1991 to 2022. Trawl and longline gear were associated with most reported incidents (n=30). The severity of the entanglements varied, with some whales experiencing no known lasting injury, and others, a majority (n= 25), suffering mortality. There are several factors that correlate with entanglement risk, including gear type, age class, and seasonality. Additionally, we summarize techniques, strategies, and best practices for entanglement responders and review potential bycatch mitigation tactics. This technical memorandum is intended to be used as a resource for researchers, policy makers, and stakeholders working to better understand and lessen the impacts of entangling materials, including fishing gear, on killer whales in Alaska.

description: Typical weighted random simplices $Z_μ$, $μ\in(-2,\infty)$, in a Poisson-Delaunay tessellation in $\mathbb{R}^n$ are considered, where the weight is given by the $(μ+1)$st power of the volume. As special cases this includes the typical ($μ=-1$) and the usual volume-weighted ($μ=0$) Poisson-Delaunay simplex. By proving sharp bounds on cumulants it is shown that the logarithmic volume of $Z_μ$ satisfies a central limit theorem in high dimensions, that is, as $n\to\infty$. In addition, rates of convergence are provided. In parallel, concentration inequalities as well as moderate deviations are studied. The set-up allows the weight $μ=μ(n)$ to depend on the dimension $n$ as well. A number of special cases are discussed separately. For fixed $μ$ also mod-$ϕ$ convergence and the large deviations behaviour of the logarithmic volume of $Z_μ$ are investigated.

description: The baryon-antibaryon asymmetry (excess of matter over antimatter in our Universe), indicated by observational data from the Cosmic Microwave Background anisotropies, predictions of primordial Nucleosynthesis, and the absence of intense radiation from matter-antimatter annihilation, constitutes an unsolved puzzle in cosmology. Two mechanisms for baryon asymmetry have been proposed as extensions of the Standard Model of Particle Physics at high energies. They rely on new couplings involving the baryon number current, one with a scalar field, called Spontaneous Baryogenesis, and the other with space-time curvature, named Gravitational Baryogenesis. These two mechanisms are investigated in the context of many bouncing scenarios, either symmetric or asymmetric around the bounce. It is shown that the constraints on the free parameters of these scenarios, imposed to yield the observed baryon-to-entropy ratio, are mild, already containing the values compatible with other observational constraints coming from the features of the power spectra of cosmological perturbations. Hence, realistic bouncing models can yield the observed baryon-antibaryon asymmetry if one of the two mechanisms proposed takes place in nature.

description: We use elastomeric polydimethylsiloxane substrates to strain single-walled carbon nanotubes and modulate their electronic properties, with the aim of developing flexible materials that can sense local strain. We demonstrate micron-scale nanotube devices that can be cycled repeatedly through strains as high as 20% while providing reproducible local strain transduction by via the device resistance. We also compress individual nanotubes, and find they undergo an undulatory distortion with a characteristic spatial period of 100-200 nm. The observed period can be understood by the mechanical properties of nanotubes and the substrate in conjunction with continuum elasticity theory. These could potentially be used to create superlattices within individual nanotubes, enabling novel devices and applications.

Design, analysis, and implementation of a DSP-based modem for Code-Phase-Shift Keying
Creators: name: Link, Robert G.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents the design, analysis, and implementation of a radio-frequency modem which employs the Code-Phase-Shift Keying (CPSK) method of Direct-Sequence Spread-Spectrum (DS-SS) signaling. A correlation receiver is designed for a DSP based implementation. The received RF signal is brought to a digitally represented base-band signal by product demodulation at the nominal RF frequency, followed by low-pass filtering and dual-channel 8 bit sampling at 2 MSPS. Base-band signal processing is done on a quad TT TMS320C40 general purpose DSP. The SS spreading factor is user selectable from a range of 7 to 127; with corresponding data rates in the range 100 to 9.4 KBPS. The herein designed tracking and acquisition algorithms are adapted from those of conventional DS-SS systems; while the carrier-phase tracking problem is solved by a new method hereby called Phase-Invariant-Reception (PIR). Extensive bit-error-rate (BER) measurements have been made in Additive White Gaussian Noise (AWGN) and in the presence of single tone interference. All measured BER vs SNR or BER vs JSR curves are compared to those of an ideal optimal receiver. The implementation loss, with respect to the optimal receiver, for single-channel data flow in AWGN is approximately 1.8 dB in power efficiency when the stationary receiver and transmitter use local oscillators of the same nominal frequency. The additional BER power efficiency loss as a function of the difference in frequency of the latter two oscillators, is obtained exactly analytically and is confirmed experimentally. The main contributions to the suboptimal BER performance are due to approximating the optimal correlator with an analog filter plus digital correlator, to tracking the timing slippage, and to using PIR instead of optimal coherent reception. The performance of the analog filter/digital correlator combination is obtained approximately analytically, and found to be independent of the signal-to-noise ratio. The BER degradation incurred by the tracking is derived analytically and found to be negligible for the timing error induced by the typical present day TTL clock oscillators, unless the SNR is very high. The theoretical BER performance of PIR is obtained exactly analytically, and found to approach that of coherent reception as the SNR increases. In addition, measured data for the mean time-to-acquire and the mean time-to-loselock in AWGN is presented; along with an outline on how these curves could be obtained analytically, and their implications for packet transmission.

description: We present an Effective Field Theory based reconstruction of quintessence models of dark energy directly from cosmological data. We show that current cosmological data possess enough constraining power to test several quintessence model properties for redshifts $z\in [0,1.5]$ with no assumptions about the behavior of the scalar field potential. We use measurements of the cosmic microwave background, supernovae distances, and the clustering and lensing of galaxies to constrain the evolution of the dark energy equation of state, Swampland Conjectures, the shape of the scalar field reconstructed potential, and the structure of its phase space. The standard cosmological model still remains favored by data and, within quintessence models, deviations from its expansion history are bounded to be below the 10% level at 95% confidence at any redshift below $z=1.5$.

description: This United States Marine Debris Emergency Response Guide (Guide) serves as a national-level reference for marine debris response. The purpose of this Guide is to improve preparedness for response and recovery operations following a disaster that generates large amounts of marine debris in the United States. This tool serves as a reference for all U.S. states and territories and supports regional and national planning and response efforts. Because all incidents are different, some aspects of marine debris response are subjective and not solely dependent on prevailing roles and authorities. This is especially true following a major, catastrophic, or unprecedented incident. This document seeks to capture the most likely response structures and actions at the federal level, with the understanding that state and local agency involvement is a critical component of an effective response.

description: A growing body of experiments display indirect evidence of icosahedral structures in supercooled liquid metals. Computer simulations provide more direct evidence but generally rely on approximate interatomic potentials of unproven accuracy. We use first-principles molecular dynamics simulations to generate realistic atomic configurations, providing structural detail not directly available from experiment, based on interatomic forces that are more reliable than conventional simulations. We analyze liquid copper, for which recent experimental results are available for comparison, to quantify the degree of local icosahedral and polytetrahedral order.

description: Primordial Black Holes (PBHs) serve as a unique probe to the physics of the early Universe, particularly inflation. In light of this, we study the formation of PBHs by the collapse of overdense perturbations generated during a model of warm inflation. For our model, we find that the primordial curvature power spectrum is red-tilted (spectral index $n_s<1$) at the large scale (small $k$) and is consistent with the $n_s-r$ values allowed from the CMB observations. Along with that, it has a blue-tilt ($n_s>1$) for the small PBH scales (large $k$), with a sufficiently large amplitude of the primordial curvature power spectrum required to form PBHs. These features originate because of the inflaton's coupling with the other fields during warm inflation. We discuss the role of the inflaton dissipation to the enhancement in the primordial power spectrum at the PBH scales. We find that for some parameter range of our warm inflation model, PBHs with mass $\sim 10^3$ g can be formed with significant abundance. Such tiny mass PBHs have a short lifetime $\sim 10^{-19}$ s and would have evaporated into Hawking radiation in the early Universe. Further in this study, we discuss the evaporation constraints on the initial mass fraction of the generated PBHs and the possibility of Planck mass PBH relics to constitute the dark matter.

description: A novel local evolution equation for one-dimensional interfaces is derived in the context of erosion by ion beam sputtering. We present numerical simulations of this equation which show interrupted coarsening in which an ordered cell pattern develops with constant wavelength and amplitude at intermediate distances, while the profile is disordered and rough at larger distances. Moreover, for a wide range of parameters the lateral extent of ordered domains ranges up to tens of cells. This behavior is new in the context of dynamics of surfaces or interfaces with morphological instabilities. We also provide analytical estimates for the stationary pattern wavelength and mean growth velocity.
Mode Coupling and Cavity-Quantum-Dot Interactions in a Fiber-Coupled Microdisk Cavity

description: A quantum master equation model for the interaction between a two-level system and whispering-gallery modes (WGMs) of a microdisk cavity is presented, with specific attention paid to current experiments involving a semiconductor quantum dot (QD) embedded in a fiber-coupled, AlGaAs microdisk cavity. In standard single mode cavity QED, three important rates characterize the system: the QD-cavity coupling rate g, the cavity decay rate kappa, and the QD dephasing rate gamma_perpendicular. A more accurate model of the microdisk cavity includes two additional features. The first is a second cavity mode that can couple to the QD, which for an ideal microdisk corresponds to a traveling wave WGM propagating counter to the first WGM. The second feature is a coupling between these two traveling wave WGMs, at a rate beta, due to backscattering caused by surface roughness that is present in fabricated devices. We consider the transmitted and reflected signals from the cavity for different parameter regimes of {g,beta,kappa,gamma_perpendicular}. A result of this analysis is that even in the presence of negligible roughness induced backscattering, a strongly coupled QD mediates coupling between the traveling wave WGMs, resulting in an enhanced effective coherent coupling rate g = sqrt(2)*g0 corresponding to that of a standing wave WGM with an electric field maximum at the position of the QD. In addition, analysis of the second-order correlation function of the reflected signal from the cavity indicates that regions of strong photon antibunching or bunching may be present depending upon the strength of coupling of the QD to each of the cavity modes. Such intensity correlation information will likely be valuable in interpreting experimental measurements of a strongly-coupled QD to a bi-modal WGM cavity.

Pelvic pain dead end? The role of neurostimulation

description: Chronic Pelvic Pain is a prevalent non-malignant condition in structures related to the pelvis, of either men or women, lasting for at least 6 months without proven infection or other obvious pathology. It’s prevalence is 4.3 – 8.6%. It can present as a major challenge to health care providers due to its complex etiology and poor response to therapy. Due to it’s multifactorial pathophysiology it’s management requires the knowledge of the pelvic organ systems and an understanding of all possible underlying conditions including musculoskeletal, neurologic, urologic, gynecologic, gastroenterologic and psychologic, which mandates a multidisciplinary approach in synchrony with the chronic pain service.

We present the challenging case of a 56 year old woman: A 56-year-old woman with chronic pelvic pain, characterized as an intense and constant stabbing  sensation accompanied by burning and numbness, underwent an array of investigation and surgical procedures without any relief. The patient was refractory to a 6-months trial of conventional therapy. Unconventional treatment such as radio-frequency, epidural, transcutaneous electrical nerve stimulation and hypnosis, also revealed to be unsatisfactory. A subcutaneous neurostimulator with electrodes implanted on S3-S4 nerve roots was inserted and after 3 months of neuromodulation success was achieved with a decrease in pain and major improvement on quality of life.

description: This paper is concerned with synthesizing programs based on black-box oracles: we are interested in the case where there exists an executable implementation of a component or library, but its internal structure is unknown. We are provided with just an API or function signature, and aim to synthesize a program with equivalent behavior. To attack this problem, we detail Presyn: a program synthesizer designed for flexible interoperation with existing programs and compiler toolchains. Presyn uses high-level imperative control-flow structures and a pair of cooperating predictive models to efficiently narrow the space of potential programs. These models can be trained effectively on small corpora of synthesized examples. We evaluate Presyn against five leading program synthesizers on a collection of 112 synthesis benchmarks collated from previous studies and real-world software libraries. We show that Presyn is able to synthesize a wider range of programs than each of them with less human input. We demonstrate the application of our approach to real-world code and software engineering problems with two case studies: accelerator library porting and detection of duplicated library reimplementations.

description: Positivity constraints are derived on pion-nucleon scattering amplitudes and their even-order derivatives inside the Mandelstam Triangle with the help of dispersion relations. Fairly interesting constraints are obtained on some of the low energy constants, by a combination of the chiral perturbation theory for heavy baryons and existing fitting results from available pion-nucleon phase shifts at intermediate energies.
