description: We define and study the Plancherel-Hecke probability measure on Young diagrams; the Hecke algorithm of [Buch-Kresch-Shimozono-Tamvakis-Yong '06] is interpreted as a polynomial-time exact sampling algorithm for this measure. Using the results of [Thomas-Yong '07] on jeu de taquin for increasing tableaux, a symmetry property of the Hecke algorithm is proved, in terms of longest strictly increasing/decreasing subsequences of words. This parallels classical theorems of [Schensted '61] and of [Knuth '70], respectively, on the Schensted and Robinson-Schensted-Knuth algorithms. We investigate, and conjecture about, the limit typical shape of the measure, in analogy with work of [Vershik-Kerov '77], [Logan-Shepp '77] and others on the ``longest increasing subsequence problem'' for permutations. We also include a related extension of [Aldous-Diaconis '99] on patience sorting. Together, these results provide a new rationale for the study of increasing tableau combinatorics, distinct from the original algebraic-geometric ones concerning K-theoretic Schubert calculus.

Year: 2023

description: The multiple meanings of Indigenous territory and property are explored here by means of a multidisciplinary lens. An ethnological journey through different geographies and times is undertaken to explain some property formation processes and illuminate how they unfold in the Andean region and, particularly, in Peru. Based on four core notions of anthropology—time, space, culture and power—Indigenous territory and property are described showing how land commodification has imposed detrimental effects on indigenous peoples.

description: In the second half of the twentieth century, theories were developed which asserted that property rights and the markets that develop thanks to them are the best way to manage natural resources in a reasonable and sustainable way. This tradition is in particular opposed to the idea of the economist Pigou, who considered that the only way to deal with the environmental issue was to regulate property rights and government intervention through taxes. In this article, we begin by outlining the arguments of the main economic articles that have been used as a basis for this approach, and then go on to suggest a number of theoretical critical arguments to these theses.

Impurity in a Fermi gas under non-Hermitian spin-orbit coupling
Creators: name: Sun, Jia-Zheng
Publisher: name: arXiv
Year: 2020
Subjects: subject: Quantum Gases (cond-mat.quant-gas)
subject: FOS: Physical sciences

description: We study the fate of an impurity in a two-component, non-interacting Fermi gas under a non- Hermitian spin-orbit coupling (SOC) which is generated by dissipative Raman lasers. While SOC mixes the two spin species in the Fermi gas thus modifies the single-particle dispersions, we consider the case where the impurity only interacts with one of the spin species. As a result, spectral properties of the impurity constitute an ideal probe to the dissipative Fermi gas in the background. In particular, we show that dissipation destabilizes polarons in favor of molecular formation, consistent with previous few-body studies. The dissipative nature of the Fermi gas further leads to broadened peaks in the inverse radio-frequency spectra for both the attractive and repulsive polaron branches, which could serve as signals for experimental observation. Our results provides an exemplary scenario where the interplay of non-Hermiticity and interaction can be probed.

Modification of streaming potential by precipitation of calcite in a sand-water system: laboratory measurements pH range from 4 to 12

description: Spontaneous Potentials associated with volcanic activity are often interpreted by means of the electrokinetic potential, which is usually positive in the flow direction (i.e. Zeta potential of the rock is negative). The water-rock interactions in hydrothermal zones alter the primary minerals leading to the formation of secondary minerals. This work addresses the study of calcite precipitation in a sand composed of 98% quartz and 2% calcite using streaming potential measurements. The precipitation of calcite as a secondary mineral phase, inferred by high calcite saturation indices and by a fall in permeability, has a significant effect on the electrokinetic behaviour, leading to a significant reduction in the Zeta potential (in absolute value) and even a change in sign. The measured decrease in Zeta potential from -16 mV to -27±4 mV takes place as the pH rises from 4 to 7, while it remains constant at -25±1 mV as the pH increases from 8 to 10.5. For pH higher than 10.5, calcite precipitates and is expected to coat the quartz surface. The measured Zeta potential vary from -17 to +8 mV for pH ranging from 10.6 to 11.7 depending on the amount of precipitated calcite indicated by the decrease in permeability. The observed change in sign of the electrical surface potential rules out the usual qualitative interpretation of SP anomalies in order to determine fluid circulations, even at pH lower than 9 if calcite is widely present as a secondary mineral phase, since the electrical surface potential of calcite depends also on CO2 partial pressure and [Ca2+]. Therefore SP anomalies as measured in hydrothermal field, without mineralogical analyses of hydrothermal deposits, and without geochemical fluid survey, should be interpreted with caution.

description: Several floristic treatments for Alaska exist, in which authors list plant names. However the precise meaning (i.e., circumscription) of a name can vary among those authors, causing confusion among users. It is the goal of this project to document this variation in name usage among key floras (Hultén 1968, Welsh 1974, Cody 2000, Flora of North America, Panarctic Flora 2020), while developing a documented workflow for such taxonomic usage mapping. Because of the great need for this work, we are also testing the workflow with non-specialists. Taxon concept mapping (TCM) describes the relationships between two or more taxonomic concepts or circumscriptions (referenced by a name plus publication) (Franz. et al 2008, Weakley 2015).
Inappropriate Nature

description: This paper seeks to examine from a philosophical perspective the relationship between nature and property (whether public, private or communal). The way our fossil-based societies inhabit the world clashes with the biophysical limits of the planet, which has led to the current socioecological crisis. Against this background, it is essential to rethink some classic problems also in the field of humanities. First, we outline the notion of nature as biosphere. Second, we identify some milestones in the discussion on common goods in the Western tradition. Finally, we review different approaches to the ownership of natural resources or goods (understood as the basis for human life) and highlight the importance of treating them as commons—especially in the context of the Anthropocene.

Modeling elastic and photoassisted transport in organic molecular wires: length dependence and current-voltage characteristics

description: Using a pi-orbital tight-binding model, we study the elastic and photoassisted transport properties of metal-molecule-metal junctions based on oligophenylenes of varying lengths. The effect of monochromatic light is modeled with an ac voltage over the contact. We first show how the low-bias transmission function can be obtained analytically, using methods previously employed for simpler chain models. In particular, the decay coefficient of the off-resonant transmission is extracted by considering both a finite-length chain and infinitely extended polyphenylene. Based on these analytical results, we discuss the length-dependence of the linear-response conductance, the thermopower, and the light-induced enhancement of the conductance in the limit of weak intensity and low frequency. In general the conductance-enhancement is calculated numerically as a function of the light frequency. Finally, we compute the current-voltage characteristics at finite dc voltages, and show that in the low-voltage regime, the effect of low-frequency light is to induce current steps with a voltage separation determined by twice the frequency. These effects are more pronounced for longer molecules. We study two different profiles for the dc and ac voltages, and it is found that the results are robust with respect to such variations. Although we concentrate here on the specific model of oligophenylenes, the results should be qualitatively similar for many other organic molecules with a large enough electronic gap.

Theory and application of the momentary fourier transform
Creators: name: Albrecht, Sandor
Publisher: name: University of British Columbia
Year: 2009

description: The discrete Fourier transform (DFT) is a widely used tool in signal or image processing and its efficiency is important. There are applications where it is desirable to use relatively small, successive, overlapped DFTs to obtain the spectrum coefficients. The momentary Fourier transform (MFT) computes the DFT of a discrete-time sequence for every new sample in an efficient recursive form. In this thesis we give an alternate derivation of the MFT using the momentary matrix transform (MMT). Recursive and non-recursive forms of the inverse MFT are also given, which can provide efficient frequency domain manipulation (e.g. filtering). Discussion on the properties and examples of the usage of the MFT is given, followed by a survey on its efficiency. In this work we investigate the applicability of the MFT to synthetic aperture radar (SAR) signal processing, and in particular show what advantages the MFT algorithm offers to the SPECtral ANalysis (SPECAN) method and burst-mode data processing. In the SPECAN algorithm, the received signals are multiplied in the time domain by a reference function, and overlapped short length DFT’s are used to compress the data. The azimuth FM rate of the signal varies in each range cell, which leads to the issue of keeping the azimuth resolution and output sampling rate constant. After the introduction to SPECAN, we show what advantages and disadvantages the MFT has compared to the FFT algorithms. When a SAR system is operated in burst-mode, its azimuth received signal has a segmented frequency-time energy in its Doppler history. It requires that IDFTs be located at specific points in the spectral domain to perform the azimuth signal compression. After the introduction of the burst-mode data properties, we show why the short IFFT (SIFFT) algorithm has the requirement of arbitrary-length, highly-overlapped IDFTs to process burst-mode data, in which case the IMFT is shown to have computational advantages.

description: We report the results of several nonequilibrium experiments performed on superconducting/normal/superconducting (S/N/S) Josephson junctions containing either one or two extra terminals that connect to normal reservoirs. Currents injected into the junctions from the normal reservoirs induce changes in the electron energy distribution function, which can change the properties of the junction. A simple experiment performed on a 3-terminal sample demonstrates that quasiparticle current and supercurrent can coexist in the normal region of the S/N/S junction. When larger voltages are applied to the normal reservoir, the sign of the current-phase relation of the junction can be reversed, creating a "$π$-junction." We compare quantitatively the maximum critical currents obtained in 4-terminal $π$-junctions when the voltages on the normal reservoirs have the same or opposite sign with respect to the superconductors. We discuss the challenges involved in creating a "Zeeman" $π$-junction with a parallel applied magnetic field and show in detail how the orbital effect suppresses the critical current. Finally, when normal current and supercurrent are simultaneously present in the junction, the distribution function develops a spatially inhomogeneous component that can be interpreted as an effective temperature gradient across the junction, with a sign that is controllable by the supercurrent. Taken as a whole, these experiments illustrate the richness and complexity of S/N/S Josephson junctions in nonequilibrium situations.

description: The isothermal gas sphere is a particular type of Lane-Emden equation and is used widely to model many problems in astrophysics like stars, star clusters, and the formation of galaxies. In this paper, we present a computational scheme to simulate the conformable fractional isothermal gas sphere using an artificial neural network (ANN) technique and compare the obtained results with the analytical solution deduced using the Taylor series. We performed our calculations, trained the ANN, and tested it using a wide range of the fractional parameter. Besides the Emden functions, we calculated the mass-radius relations and the density profiles of the fractional isothermal gas spheres. The results obtained provided that ANN could perfectly simulate the conformable fractional isothermal gas spheres.

description: We show that spin-dependent electron-phonon interaction in the energy relaxation of a two-dimensional electron gas results in equal and oppositely directed currents in the spin-up and spin-down subbands yielding a pure spin current. In our experiments on SiGe heterostructures the pure spin current is converted into an electric current applying a magnetic field that lifts the cancellation of the two partial charge flows. A microscopic theory of this effect, taking account of the asymmetry of the relaxation process, is developed being in a good agreement with the experimental data.

On Universaling ‘Nature’ and ‘Property’: the Unravelling of a Master Narrative

description: In this paper I will show why the master narrative that leading thinkers in the West have forged to justify property as an engine of progress is unravelling, and why the future will never be the same, as far as the relationship between property and nature is concerned. Property and markets will remain important to our existence, but a healthy dose of realism and political wisdom by now defeats any narrative that extols the supposed superior virtues of property and markets in regulating human interactions with nature. It is time to look elsewhere to find solutions to have a more sustainable relationship with nature; it is necessary to recognise that there are other ways to think to these problems and to our future.

Nature, Bodies, and Land

description: Rooted in medieval juridical thinking, early modern legal culture saw community’s law as the expression of an underlying order of things, something defined not by the willing agreement of the parts that constituted the community, but rather by nature and nurture. For the Iberian world, this belief was expressed in the idea of the ‘señorío natural’, which according to legal doctrine was a bond that linked subjects to the land where they were born and subjected them to a common jurisdiction (Hespanha, Uncommon Laws). Communities and all kinds of corporate bodies thus also had a natural origin, which points to an intertwinement, and not a contradiction, between nature and different kinds of collective bodies. These bodies—corporations, guilds, communities, families, and so on—were the basis for the assignment of rights, obligations, privileges, and duties, but also for the distribution of access to land. This article seeks to reframe ownership and property within this framework as a way of rethinking the ways in which communities defined their relations to land.

description: We present a spectrum of experimental data on the fractional quantum Hall effect (FQHE) states in the first excited Landau level, obtained in an ultrahigh mobility two-dimensional electron system (2DES) and at very low temperatures and report the following results: For the even-denominator FQHE states, the sample dependence of the nu=5/2 state clearly shows that disorder plays an important role in determining the energy gap at nu=5/2. For the developing nu=19/8 FQHE state the temperature dependence of the Rxx minimum implies an energy gap of ~5mK.The energy gaps of the odd-denominator FQHE states at nu=7/3 and 8/3 also increase with decreasing disorder, similar to the gap at 5/2 state. Unexpectedly and contrary to earlier data on lower mobility samples, in this ultra-high quality specimen, the nu=13/5 state is missing, while its particle-hole conjugate state, the nu=12/5 state, is a fully developed FQHE state. We speculate that this disappearance might indicate a spin polarization of the nu=13/5 state. Finally, the temperature dependence is studied for the two-reentrant integer quantum Hall states around nu=5/2 and is found to show a very narrow temperature range for the transition from quantized to classical value.

description: Inspired by how the human brain employs more neural pathways when increasing the focus on a subject, we introduce a novel twin cascaded attention model that outperforms a state-of-the-art image captioning model that was originally implemented using one channel of attention for the visual grounding task. Visual grounding ensures the existence of words in the caption sentence that are grounded into a particular region in the input image. After a deep learning model is trained on visual grounding task, the model employs the learned patterns regarding the visual grounding and the order of objects in the caption sentences, when generating captions. We report the results of our experiments in three image captioning tasks on the COCO dataset. The results are reported using standard image captioning metrics to show the improvements achieved by our model over the previous image captioning model. The results gathered from our experiments suggest that employing more parallel attention pathways in a deep neural network leads to higher performance. Our implementation of NTT is publicly available at: https://github.com/zanyarz/NeuralTwinsTalk.
title: Synthese abbaubarer fluorierter Polymerarchitekturen zur Anwendung als funktionale Beschichtungen und responsive Materialien
Creators: name: Kredel, Julia

Year: 2021

description: Ziel der vorliegenden Arbeit war die Einführung verschiedener hochfluorierter Materialien in die Polymerisation zur Herstellung verschiedener Polymerarchitekturen und funktionalen Beschichtungen. Aufgrund der Vielzahl an außergewöhnlichen Eigenschaften gewann die Klasse der Fluorpolymere in den letzten Jahren immer mehr Aufmerksamkeit in der Forschung und sie sind als Hochleistungsmaterialien nicht mehr aus dem alltäglichen Leben wegzudenken. Mit dem Fokus auf den optischen Eigenschaften der Fluorpolymere können über eine starved-feed Emulsionspolymerisation Kern-Schale Partikel hergestellt werden und hieraus über das Schmelze Scheer Verfahren Opalfilme gepresst werden, bei denen das Fluorpolymer eine stabile Matrix mit hohem Brechungsindexkontrast zum Kernmaterial bildet. Darüber hinaus können durch die Entfernung der Kernmaterialien diese Opalfilme auch invertiert werden und ein vollständig poröses Material bilden. Durch die Synthese von Partikeln mit weichem Kern, einer harten aber stabilen Zwischenschicht und einer weichen Schale, sowie einer geeigneten Vernetzung des Matrixmaterials können zudem brillante Opalfilme hergestellt werden, die reversibel mit einem Farbwechsel auf Druck reagieren. Durch eine weitere Vernetzung können eingedrückte Farbbilder auf dem Opalfilm irreversibel fixiert werden. Darüber hinaus wird im zweiten Teil der Arbeit ein hochfluoriertes Coating-Material aus einem neuartigen nicht perfluorierten Monomer (PPVE-Mercaptoethanol-Acrylate), zur Anwendung auf Textilien für eine Wasser- und auch Ölabweisung hergestellt. Die Anwendung des neuartigen Monomers hat gegenüber den konventionellen perfluorierten Materialien den Vorteil, dass es atmosphärisch abbaubar ist. Diese Abbaubarkeit wird durch die Behandlung mit Ozon untersucht und eine Fragmentierung des Polymers bewiesen.

description: It is an open challenge to estimate systematically the physical parameters of neutron star interiors from pulsar timing data while separating spin wandering intrinsic to the pulsar (achromatic timing noise) from measurement noise and chromatic timing noise (due to propagation effects). In this paper we formulate the classic two-component, crust-superfluid model of neutron star interiors as a noise-driven, linear dynamical system and use a state-space-based expectation-maximization method to estimate the system parameters using gravitational-wave and electromagnetic timing data. Monte Carlo simulations show that we can accurately estimate all six parameters of the two-component model provided that electromagnetic measurements of the crust angular velocity, and gravitational-wave measurements of the core angular velocity, are both available. When only electromagnetic data are available we can recover the overall relaxation time-scale, the ensemble-averaged spin-down rate, and the strength of the white-noise torque on the crust. However, the estimates of the secular torques on the two components and white noise torque on the superfluid are biased significantly.

description: Dipolar coupled homonuclear spins present challenging, yet useful systems for quantum information processing. In such systems, eigenbasis of the system Hamiltonian is the appropriate computational basis and coherent control can be achieved by specially designed strongly modulating pulses. In this letter we describe the first experimental implementation of the quantum algorithm for numerical gradient estimation on the eigenbasis of a four spin system.

description: We exploit multiband Hubble Space Telescope photometry to investigate multiple populations (MPs) along the red
 horizontal branches (HBs) and red clumps of 14 metal-rich globular clusters (GCs), including 12 Milky Way GCs
 and the Magellanic Cloud GCs NGC 1978 and NGC 416. Based on appropriate two-color diagrams, we find that
 the fraction of first-generation (1G) stars in Galactic GCs correlates with cluster mass, confirming previous results
 based on red-giant branch (RGB) stars. Magellanic Cloud GCs show higher fractions of 1G stars than Galactic GCs
 with similar masses, thus suggesting that the environment affects the MP phenomenon. We compared and
 combined our population fractions based on the HB with previous estimates from the MS and RGB, and we used
 ground-based UBVI photometry (available for NGC 104, NGC 5927, NGC 6366, and NGC 6838) to extend the
 investigation over a wide field of view. All studied GCs are consistent with flat distributions of 1G and second-
 generation (2G) stars within ∼1′ from the cluster center except NGC 416, where the 2G is more centrally
 concentrated. 2G stars of NGC 104 and NGC 5927 are more centrally concentrated than the 1G stars, whereas the
 distribution is flat for NGC 6366 and NGC 6838. We discover that most of the analyzed GCs exhibit extended
 sequences of 1G stars along the red HB, not consistent with a simple population. The comparison between
 appropriate synthetic and observed CMDs reveals that these extended distributions are consistent with either star-
 to-star variation in helium or with an internal metallicity spread, recalling the inhomogeneity of 1G stars along the
 chromosome maps.

description: Single-filament tracing has been a valuable tool to directly determine geometrical and mechanical properties of entangled polymer networks. However, systematically verifying how the stiffness of the tracer filament or its molecular interactions with the surrounding network impacts the measurement of these parameters has not been possible with the established experimental systems. Here, we use mechanically programmable DNA nanotubes embedded in crosslinked and entangled F-actin networks, as well as in synthetic DNA networks, in order to measure fundamental, structural network properties like tube width and mesh size with respect to the stiffness of the tracers. While we confirm some predictions derived from models based purely on steric interactions, our results indicate that these models should be expanded to account for additional inter-filament interactions, thus describing the behavior of real polymer networks.

description: Two-dimensional (2D) transition metal dichalcogenides (TMDCs) with unique electrical properties are fascinating materials used for future electronics. However, the strong Fermi level pinning effect at the interface of TMDCs and metal electrodes always leads to high contact resistance, which seriously hinders their application in 2D electronics. One effective way to overcome this is to use metallic TMDCs or transferred metal electrodes as van der Waals (vdW) contacts. Alternatively, using highly conductive doped TMDCs will have a profound impact on the contact engineering of 2D electronics. Here, a novel chemical vapor deposition using mixed molten salts is established for vapor-liquid-solid growth of high-quality rhenium (Re) and vanadium (V)-doped TMDC monolayers with high controllability and reproducibility. A tunable semiconductor to metal transition is observed in the Re and V-doped TMDCs. Electrical conductivity increases up to a factor of 108 in the degenerate V-doped WS2 and WSe2. Using V-doped WSe2 as vdW contact, the on-state current and on/off ratio of WSe2-based field-effect transistors have been substantially improved (from ~10-8 to 10-5 A; ~104 to 108), compared to metal contacts. Future studies on lateral contacts and interconnects using doped TMDCs will pave the way for 2D integrated circuits and flexible electronics.

title: Variation in selection and its evolutionary consequences

description: It is widely appreciated that many aspects of selection change temporally when populations experience stochastic environments. However, the long term consequences for adaptive evolution has received less consideration. The availability of long term data, including phenotypic and life history information, along with high quality pedigrees, allows old approaches and theoretical ideas to be re-considered, and applied, empirically. To investigate viability selection in a wild population of Soay sheep (Ovis aries) I estimated the sensitivity of selection to changes in population size. Using environmentally structured ﬁtness functions I investigated pathways through which changes in population size drive changes in selection estimates. Much of the observed variation in selection was driven by changes in mean ﬁtness. If generally true in other populations this may have important consequences regarding the occurrence of ﬂuctuating selection. I then developed a method to estimate both individual, and cohort, success using theory based around Fisher’s reproductive value. This approach overcomes some complications associated with overlapping generations and age structure common in natural populations. Using pedigree information I tracked relative contributions to the future population through time and additionally used alternative theory from demographic literature to calculate stochastic total cohort reproductive values. The different estimates corresponded closely. Finally, I weighted selection differentials by measures of cohort reproductive success. When generations overlap, correctly considering the contribution a cohort makes to the future population can greatly reduce the expected response, as cohorts that experience stronger selection typically contribute less. This might provide one explanation for the paradox of stasis. By linking approaches from multiple different ﬁelds with high quality, long term, data, I demonstrate that ecological pathways that inﬂuence selection can be identiﬁed, providing greater understanding of longer term evolutionary dynamics. Further applications of the methods developed could generate opportunities to investigate generalities in temporal evolutionary patterns not previously considered.

description: We present the first simultaneous measurement of the ratio of branching fractions, R=B(t->Wb)/B(t->Wq), with q being a d, s, or b quark, and the top quark pair production cross section sigma_ttbar in the lepton plus jets channel using 0.9 fb-1 of ppbar collision data at sqrt(s)=1.96 TeV collected with the D0 detector. We extract R and sigma_ttbar by analyzing samples of events with 0, 1 and >= 2 identified b jets. We measure R = 0.97 +0.09-0.08 (stat+syst) and sigma_ttbar = 8.18 +0.90-0.84 (stat+syst)} +/-0.50 (lumi) pb, in agreement with the standard model prediction.

Transmission of JPEG compressed images over the wireless CDPD network

Publisher: name: University of British Columbia

description: Image transmission over bandwidth limited wireless networks is becoming increasingly popular [1]. To transmit an image over a low bit rate wireless network efficiently is not an easy task, because wireless networks normally have a high bit error rate. In this thesis, we propose a Progressive Image Transmission Protocol (PITP) which transmits a JPEG progressively compressed image effectively over wireless networks that support the Internet Protocol (LP), and more specifically the Cellular Digital Packet Data (CDPD) network. In the first part of the thesis, we will study the CDPD network, the LP network protocol, and the TCP and the UDP transport layer protocols. In the second part of the thesis, we will study the JPEG compression algorithm. In the last part of the thesis, we will discuss the Progressive Image Transmission Protocol (PITP) that is used to transmit an image over the CDPD wireless network. The PITP is a selective re-transmission application layer protocol which employs a JPEG progressive compression algorithm, the UDP transport protocol and a segment re-transmission algorithm. The segment retransmission algorithm is based on the priority levels of the JPEG scans and the current wireless network conditions. The segment re-transmission algorithm is so flexible that the performance of the PITP system can be adjusted by simply optimizing a few parameters in the algorithm. Simulations were performed to evaluate the efficiency and the effectiveness of the PITP. Our simulation results indicate that the PITP yields a substantially better image transmission rate than that achieved by conventional TCP/IP.
