description: Siamese network-based trackers have shown remarkable success in aerial tracking. Most previous works, however, usually perform template matching only between the initial template and the search region and thus fail to deal with rapidly changing targets that often appear in aerial tracking. As a remedy, this work presents Building Appearance Collection Tracking (BACTrack). This simple yet effective tracking framework builds a dynamic collection of target templates online and performs efficient multi-template matching to achieve robust tracking. Specifically, BACTrack mainly comprises a Mixed-Temporal Transformer (MTT) and an appearance discriminator. The former is responsible for efficiently building relationships between the search region and multiple target templates in parallel through a mixed-temporal attention mechanism. At the same time, the appearance discriminator employs an online adaptive template-update strategy to ensure that the collected multiple templates remain reliable and diverse, allowing them to closely follow rapid changes in the target's appearance and suppress background interference during tracking. Extensive experiments show that our BACTrack achieves top performance on four challenging aerial tracking benchmarks while maintaining an impressive speed of over 87 FPS on a single GPU. Speed tests on embedded platforms also validate our potential suitability for deployment on UAV platforms.

description: Tunable photovoltaic photodetectors are of significant relevance in the fields of programmable and neuromorphic optoelectronics. However, their widespread adoption is hindered by intricate architectural design and energy consumption challenges. This study employs a nonvolatile MoTe2/hBN/graphene semi-floating photodetector to address these issues. Programed with pulsed gate voltage, the MoTe2 channel can be reconfigured from an n+-n to a p-n homojunction, and the photocurrent transition changes from negative to positive values. Scanning photocurrent mapping reveals that the negative and positive photocurrents are attributed to Schottky junction and p-n homojunction, respectively. In the p-n configuration, the device demonstrates self-driven, linear, rapid response (~3 ms), and broadband sensitivity (from 405 to 1500 nm) for photodetection, with typical performances of responsivity at ~0.5 A/W and detectivity ~1.6*10^12 Jones under 635 nm illumination. These outstanding photodetection capabilities emphasize the potential of the semi-floating photodetector as a pioneering approach for advancing logical and nonvolatile optoelectronics.

description: Neural network approaches in recommender systems have shown remarkable success by representing a large set of items as a learnable vector embedding table. However, infrequent items may suffer from inadequate training opportunities, making it difficult to learn meaningful representations. We examine that in attribute and context-aware settings, the poorly learned embeddings of infrequent items impair the recommendation accuracy. To address such an issue, we propose a proxy-based item representation that allows each item to be expressed as a weighted sum of learnable proxy embeddings. Here, the proxy weight is determined by the attributes and context of each item and may incorporate bias terms in case of frequent items to further reflect collaborative signals. The proxy-based method calculates the item representations compositionally, ensuring each representation resides inside a well-trained simplex and, thus, acquires guaranteed quality. Additionally, that the proxy embeddings are shared across all items allows the infrequent items to borrow training signals of frequent items in a unified model structure and end-to-end manner. Our proposed method is a plug-and-play model that can replace the item encoding layer of any neural network-based recommendation model, while consistently improving the recommendation performance with much smaller parameter usage. Experiments conducted on real-world recommendation benchmark datasets demonstrate that our proposed model outperforms state-of-the-art models in terms of recommendation accuracy by up to 17% while using only 10% of the parameters.

description: Two-dimensional (2D) material photodetectors have gained great attention as potential elements for optoelectronic applications. However, the linearity of the photoresponse is often compromised by the carrier interaction, even in 2D photodiodes. In this study, we present a new device concept of dual-floating van der Waals heterostructures (vdWHs) photodiode by employing ambipolar MoTe2 and n-type MoS2 2D semiconductors. The presence of type II heterojunctions on both sides of channel layers effectively deplete carriers and restrict the photocarrier trapping within the channel layers. As a result, the device exhibits robust linear photoresponse under photovoltaic mode from the visible (405 nm) to near-infrared (1600 nm) band. With the built-in electric field of the vdWHs, we achieve a linear dynamic range of ~ 100 dB, responsivity of ~ 1.57 A/W, detectivity of ~ 4.28 * 10^11 Jones, and response speed of ~ 30 μs. Our results showcase a promising device concept with excellent linearity towards fast and low-loss detection, high-resolution imaging, and logic optoelectronics.

description: The concept of Schramm-Loewner evolution provides a unified description of domain boundaries of many lattice spin systems in two dimensions, possibly even including systems with quenched disorder. Here, we study domain walls in the random-field Ising model. Although, in two dimensions, this system does not show an ordering transition to a ferromagnetic state, in the presence of a uniform external field spin domains percolate beyond a critical field strength. Using exact ground state calculations for very large systems, we examine ground state domain walls near this percolation transition finding strong evidence that they are conformally invariant and satisfy the domain Markov property, implying compatibility with Schramm-Loewner evolution (SLE$_κ$) with parameter $κ= 6$. These results might pave the way for new field-theoretic treatments of systems with quenched disorder.

We present results from a mini-dictator game, in which the recipient can send a free-form text message to the dictator before the latter decides. We find that putting effort into the message, writing in a humorous way and mentioning reasons why the money is needed pays off. Additionally, we find differences in the behavior of male and female dictators. Only men react positively to efficiency arguments, while only women react to messages that emphasize the dictator’s power and responsibility.

Creators: name: Ayzel, Georgy

Publisher: name: Universität Potsdam
Year: 2019

description: The Aral Sea desiccation and related changes in hydroclimatic conditions on a regional level is a hot topic for past decades. The key problem of scientific research projects devoted to an investigation of modern Aral Sea basin hydrological regime is its discontinuous nature – the only limited amount of papers takes into account the complex runoff formation system entirely. Addressing this challenge we have developed a continuous prediction system for assessing freshwater inflow into the Small Aral Sea based on coupling stack of hydrological and data-driven models. Results show a good prediction skill and approve the possibility to develop a valuable water assessment tool which utilizes the power of classical physically based and modern machine learning models both for territories with complex water management system and strong water-related data scarcity. The source code and data of the proposed system is available on a Github page (https://github.com/SMASHIproject/IWRM2018).

description: We present a prescription for computing the gluon fusion production rate of a composite Higgs boson, which arises as a pseudo-Nambu-Goldstone boson, using effective lagrangians. The calculation incorporates three different effects due to the composite nature of the Higgs, some of which were neglected previously. We apply the prescription to models with and without the collective breaking mechanism. In sharp contrast with the case of a fundamental Higgs scalar, the rate only depends on the decay constant "f" and is not sensitive to masses of new particles. After including electroweak constraints, there is a substantial reduction in the rate, in the range of 10 -- 30 % or greater.

Free particle wavefunction in light of the minimum-length deformed quantum mechanics and some of its phenomenological implications

description: At a fundamental level the notion of particle (quantum) comes from quantum field theory. From this point of view we estimate corrections to the free particle wave function due to minimum-length deformed quantum mechanics to the first order in the deformation parameter. Namely, in the matrix element $<0 |\varPhi(t,\,\mathbf{x}) |\mathbf{p} >$ that in the standard case sets the free particle wave function $\propto \exp(i[\mathbf{p}\mathbf{x} - ε(\mathbf{p}) t])$ there appear three kinds of corrections when the field operator is calculated by using the minimum-length deformed quantum mechanics. Starting from the standard (not modified at the classical level) Lagrangian, after the field quantization we get a modified dispersion relation, and besides that we find that the particle's wave function contains a small fractions of an antiparticle wave function and the backscattered wave. The result leads to interesting implications for black hole physics.

A novel conception of consciousness as a complex-adaptive-system of Markov blankets

subject: Other education not elsewhere classified

description: The study of consciousness has faced two major problems: lack of consensus regarding what consciousness is, and incomplete understanding of conscious and unconscious mechanisms responsible for the emergence of mental states. This thesis is an effort to circumvent these problems by proposing a novel schema of consciousness based on principles from complex-adaptive-systems, predictive processing and emergentism. The central claim is that consciousness can be defined by the interactions of conditionally independent component sub-systems, referred to as agents, which organise themselves hierarchically. The proposed schema of consciousness comprises three primary sub-systems: 1) a reservoir of states that manifest in unconscious form, including potential knowledge, referred to as the unconscious Markov blanket; 2) a conscious Markov blanket that functions to convert some unconscious information into conscious form, generating a conscious lower-base (the state of the world), and; 3) a (first person) mental component that functions to capture the conscious lower-base, convert it into phenomenological experiences and implement mental action to add novelty to the state of the world.The schema shows that consciousness sub-systems are conditionally interdependent, separated by their statistical membranes. They communicate through a two-phased bi-directional cycle. During the top-down causality phase, the consciousness system’s higher-level information influences the sensory-state of the membrane of lower-level component parts, enslaving them. In the bottom-up emergent phase sub-systems process this information, adding novelty to it and, through the active-state of their membranes generate individuals’ conscious mental states. I conclude that individuals do not ‘have’ a consciousness but rather occupy a mental position within the consciousness system. Finally, I argue that the strength of the model lies in its well-researched principles; but it is weak in that is based, by and large, on ‘theory-to-fact’ abductive inferences that require validation.

“Without internet, we have no existence” : Rohingya refugee representation on social media
Creators: name: Sonia, Shorif
Publisher: name: University of British Columbia
Year: 2023

description: In the media, migrants, and refugee literature, representation of the refugees is one of the most recurring and contested issues. From the news media to digital or social media platforms to humanitarian communications, a dualism of refugee representation is evident: ‘threats’ vs. ‘victims.’ The humanitarian agencies have been widely criticized for the dehumanized representation of refugees as ‘weak,’ ‘victims,’, and ‘in need of charity for fundraising. According to the United Nations High Commissioner for Refugees, almost 65 million forcibly displaced populations rarely have access to connectivity to raise their opinions. This research investigates the problem of representation about access to connectivity and the internet for the Rohingya refugees in Bangladesh. I ask, how are Rohingya refugees represented on social media? This thesis argues that the humanitarian agencies and the refugees are creating a convergent portrayal of refugee ‘agency’ shifting from the traditional victim vs. threats representation. The thesis further strengthens the understanding of refugee self-representation, considering technological mediation. Analysis of 32 weeks of social media data of 4 humanitarian agencies and 10 Rohingya refugees and their interviews explore beyond the traditional ‘threats’ vs. ‘victims’ refugee representation. Through the qualitative data analysis, this research sheds light on how such a negative narrative has changed and leading humanitarian agencies working in Cox’s Bazar, Bangladesh, for the Rohingya refugee response are creating an assertive representation of the refugees by showing them as ‘resilient,’ ‘active,’ ‘self-reliant’ and ‘peaceful’; reflecting how the Rohingya refugees represent themselves. As a policy recommendation, I highlight the importance of connectivity and the internet for refugees to express themselves.

description: Hepcidin-25 was identified as themain iron regulator in the human body, and it by binds to the sole iron-exporter ferroportin. Studies showed that the N-terminus of hepcidin is responsible for this interaction, the same N-terminus that encompasses a small copper(II) binding site known as the ATCUN (amino-terminal Cu(II)- and Ni(II)-binding) motif. Interestingly, this copper-binding property is largely ignored in most papers dealing with hepcidin-25. In this context, detailed investigations of the complex formed between hepcidin-25 and copper could reveal insight into its biological role. The present work focuses on metal-bound hepcidin-25 that can be considered the biologically active form. The first part is devoted to the reversed-phase chromatographic separation of copper-bound and copper-free hepcidin-25 achieved by applying basic mobile phases containing 0.1% ammonia. Further, mass spectrometry (tandemmass spectrometry (MS/MS), high-resolutionmass spectrometry (HRMS)) and nuclear magnetic resonance (NMR) spectroscopy were employed to characterize the copper-peptide. Lastly, a three-dimensional (3D)model of hepcidin-25with bound copper(II) is presented. The identification of metal complexes and potential isoforms and isomers, from which the latter usually are left undetected by mass spectrometry, led to the conclusion that complementary analytical methods are needed to characterize a peptide calibrant or referencematerial comprehensively. Quantitative nuclear magnetic resonance (qNMR), inductively-coupled plasma mass spectrometry (ICP-MS), ion-mobility spectrometry (IMS) and chiral amino acid analysis (AAA) should be considered among others.

description: The conjecture that the ancient globular clusters (GCs) formed at the center of their own dark matter halos was first proposed by Peebles (1984), and has recently been revived to explain the puzzling abundance patterns observed within many GCs. In this paper we demonstrate that the outer stellar density profile of isolated GCs is very sensitive to the presence of an extended dark halo. The GCs NGC 2419, located at 90 kpc from the center of our Galaxy, and MGC1, located at ~200 kpc from the center of M31, are ideal laboratories for testing the scenario that GCs formed at the centers of massive dark halos. Comparing analytic models to observations of these GCs, we conclude that these GCs cannot be embedded within dark halos with a virial mass greater than 10^6 Msun, or, equivalently, the dark matter halo mass-to-stellar mass ratio must be Mdm/M_*<1. If these GCs have indeed orbited within weak tidal fields throughout their lifetimes, then these limits imply that these GCs did not form within their own dark halos. Recent observations of an extended stellar halo in the GC NGC 1851 are also interpreted in the context of our analytic models. Implications of these results for the formation of GCs are briefly discussed.

description: The semiarid northeast of Brazil is one of the most densely populated dryland regions in the world and recurrently affected by severe droughts. Thus, reliable seasonal forecasts of streamflow and reservoir storage are of high value for water managers. Such forecasts can be generated by applying either hydrological models representing underlying processes or statistical relationships exploiting correlations among meteorological and hydrological variables. This work evaluates and compares the performances of seasonal reservoir storage forecasts derived by a process-based hydrological model and a statistical approach.

Driven by observations, both models achieve similar simulation accuracies. In a hindcast experiment, however, the accuracy of estimating regional reservoir storages was considerably lower using the process-based hydrological model, whereas the resolution and reliability of drought event predictions were similar by both approaches. Further investigations regarding the deficiencies of the process-based model revealed a significant influence of antecedent wetness conditions and a higher sensitivity of model prediction performance to rainfall forecast quality.

Within the scope of this study, the statistical model proved to be the more straightforward approach for predictions of reservoir level and drought events at regionally and monthly aggregated scales. However, for forecasts at finer scales of space and time or for the investigation of underlying processes, the costly initialisation and application of a process-based model can be worthwhile. Furthermore, the application of innovative data products, such as remote sensing data, and operational model correction methods, like data assimilation, may allow for an enhanced exploitation of the advanced capabilities of process-based hydrological models.

description: Predicting the future trajectories of dynamic agents in complex environments is crucial for a variety of applications, including autonomous driving, robotics, and human-computer interaction. It is a challenging task as the behavior of the agent is unknown and intrinsically multimodal. Our key insight is that the agents behaviors are influenced not only by their past trajectories and their interaction with their immediate environment but also largely with their long term waypoint (LTW). In this paper, we study the impact of adding a long-term goal on the performance of a trajectory prediction framework. We present an interpretable long term waypoint-driven prediction framework (WayDCM). WayDCM first predict an agent's intermediate goal (IG) by encoding his interactions with the environment as well as his LTW using a combination of a Discrete choice Model (DCM) and a Neural Network model (NN). Then, our model predicts the corresponding trajectories. This is in contrast to previous work which does not consider the ultimate intent of the agent to predict his trajectory. We evaluate and show the effectiveness of our approach on the Waymo Open dataset.

title: Presupposition Accommodation of the German Additive Particle auch (= “too”)
Creators: name: Grubic, Mira

Publisher: name: Universität Potsdam
Year: 2019

description: Presupposition triggers differ with respect to whether their presupposition is easily accommodatable. The presupposition of focus-sensitive additive particles like also or too is often classified as hard to accommodate, i.e., these triggers are infelicitous if their presupposition is not entailed by the immediate linguistic or non-linguistic context. We tested two competing accounts for the German additive particle auch concerning this requirement: First, that it requires a focus alternative to the whole proposition to be salient, and second, that it merely requires an alternative to the focused constituent (e.g., an individual) to be salient. We conducted two experiments involving felicity judgments as well as questions asking for the truth of the presupposition to be accommodated. Our results suggest that the latter account is too weak: mere previous mention of a potential alternative to the focused constituent is not enough to license the use of auch. However, our results also suggest that the former account is too strong: when an alternative of the focused constituent is prementioned and certain other accommodation-enhancing factors are present, the context does not have to entail the presupposed proposition. We tested the following two potentially accommodation-enhancing factors: First, whether the discourse can be construed to be from the perspective of the individual that the presupposition is about, and second, whether the presupposition is needed to establish coherence between the host sentence of the additive particle and the preceding context. The factor coherence was found to play a significant role. Our results thus corroborate the results of other researchers showing that discourse participants go to great lengths in order to identify a potential presupposition to accommodate, and we contribute to these results by showing that coherence is one of the factors that enhance accommodation.

description: The aim of this essay is to give an overview about recent developments of the government innovation funds of Sweden and Finland. In order to discover recent developments basic knowledge regarding innovation funds, funding structures and information about the two big funding agencies Vinnova Sweden and Business Finland is presented. Building on this information, the developments of the two funding agencies are compared and examined for similarities and differences. Both countries have a very similar structure in terms of the R&D sector and are striving with the same issues. Just as sustainability is a leading issue, the collaboration between the different shareholders is another main challenge. Both topics were negatively affected by the COVID-19 pandemic. Both Sweden and Finland had to really push forward innovation with financial support and political, strategic goals. Even though there are strong recent developments, the countries are facing the same challenges, do have similar funding structures and therefore have no big comparative strengths or weaknesses to each other.

description: According to recent literature sodium bicarbonate (NaHCO3) has been proposed as a performance enhancing aid by reducing acidosis during exercise. The aim of the current review is to investigate if the duration of exercise is an essential factor for the effect
of NaHCO3. To collect the latest studies from electronic database
of PubMed, study publication time was restricted from December 2006 to December 2016. The search was updated in July 2018. The studies were divided into exercise durations of > 4 or ≤ 4 minutes for easier comparability of their effects in different exercises. Only randomized controlled trials were included in this review. Of the 775 studies, 35 met the inclusion criteria. Study design, subjects, effects as well as outcome criteria were inconsistent throughout the studies. Seventeen of these studies reported
performance enhancing effects after supplementing NaHCO3. Eleven of twenty studies with exercise duration of ≤ 4 minutes showed positive and four diverse results after supplementing NaHCO3. On the other hand six of fifteen studies with an exercise duration of >4 minutes showed performance enhancing and two studies showed diverse results. Consequently, the duration of exercise might be influential for inducing a performance enhancing effect when supplementing NaHCO3, but to which extent, remains unclear due to the inconsistencies in the study results.

Nonequilibrium phase transition in the kinetic Ising model driven by propagating magnetic field wave
Creators: name: Acharyya, Muktish
Publisher: name: arXiv
Year: 2010
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The two dimensional ferromagnetic Ising model in the presence of a propagating magnetic field wave (with well defined frequency and wavelength) is studied by Mone Carlo simulation. This study differs from all of the earlier studies done so far, where the oscillating magnetic field was considered to be uniform in space. The time average magnetisation over a full cycle (the time period) of the propagating magnetic field acts as the dynamic order parameter. The dynamical phase transition is observed. The temperature variation of the dynamic order parameter, the mean square deviation of the dynamic order parameter, the dynamic specific heat and the derivative of the dynamic order parameter are studied. The mean square deviation of the dynamic order parameter, dynamic specific heat show sharp maxima near the transition point. The derivative of dynamic order parameter shows sharp minimum near the transition point. The transition temperature is found to depend also on the speed of propagation of the magnetic field wave.

description: Unmanned aerial vehicles (UAVs) are expected to be an integral part of wireless networks, and determining collision-free trajectory in multi-UAV non-cooperative scenarios while collecting data from distributed Internet of Things (IoT) nodes is a challenging task. In this paper, we consider a path planning optimization problem to maximize the collected data from multiple IoT nodes under realistic constraints. The considered multi-UAV non-cooperative scenarios involve random number of other UAVs in addition to the typical UAV, and UAVs do not communicate or share information among each other. We translate the problem into a Markov decision process (MDP) with parameterized states, permissible actions, and detailed reward functions. Dueling double deep Q-network (D3QN) is proposed to learn the decision making policy for the typical UAV, without any prior knowledge of the environment (e.g., channel propagation model and locations of the obstacles) and other UAVs (e.g., their missions, movements, and policies). The proposed algorithm can adapt to various missions in various scenarios, e.g., different numbers and positions of IoT nodes, different amount of data to be collected, and different numbers and positions of other UAVs.
 Numerical results demonstrate that real-time navigation can be efficiently performed with high success rate, high data collection rate, and low collision rate.

description: In this paper we demonstrate how the recently reported exactly and quasi-exactly solvable models admitting quasinormal modes can be constructed and classified very simply and directly by the newly proposed prepotential approach. These new models were previously obtained within the Lie-algebraic approach. Unlike the Lie-algebraic approach, the prepotential approach does not require any knowledge of the underlying symmetry of the system. It treats both quasi-exact and exact solvabilities on the same footing, and gives the potential as well as the eigenfunctions and eigenvalues simultaneously. We also present three new models with quasinormal modes: a new exactly solvable Morse-like model, and two new quasi-exactly solvable models of the Scarf II and generalized Pöschl-Teller types.

Temporary foreign agricultural worker exploitation in Ontario and British Columbia : why differences in provincial labour policy matter
Creators: name: Henshaw, Beatrice Edith
Publisher: name: University of British Columbia
Year: 2023

description: Temporary Foreign Agricultural Workers (TFAW) in Canada have a heightened vulnerability to exploitation and workplace abuse under the Federal Temporary Foreign Worker Program (TFWP). Despite TFAWs admittance to Canada through one of four agricultural streams in the TFWP, TFAWs deal more closely with provincial labour law, statutes, and policy. This thesis explores why TFAWs are more vulnerable to exploitation and abuse and whether differences in provincial labour policy contribute to heightened rates of exploitation. By employing the Labour Law Approach, this thesis seeks to understand the scope and severity of TFAW exploitation in Canada. Ultimately, this thesis makes two arguments. First, the current employment rules afforded to TFAWs in both Ontario (ON) and British Columbia (BC) provide insufficient protections and safeguards for the rights of TFAWs. Second, the current Labour Law Approach is unable to capture the scope and severity of the exploitation that TFAWs face in Canada. A qualitative case study based approach is utilized throughout the thesis by drawing upon Statistics Canada vignettes, legislative review, document review, and tribunal and court decisions. Ultimately, the research demonstrates that differences in provincial labour policy do affect the levels and kinds of exploitation TFAWs endure within the province they work. Occupational and safety standards that outline the rights of TFAWs in both ON and BC largely prove inadequate and further entrench TFAW vulnerability and precarity. Although BC ensures greater workplace protections for TFAWs than ON, workplace exploitation and abuse remain a serious concern in the province. Reforms to policy are recommended. Researching this reality through the Labour Law Approach proved concerning as it is likely unable to capture the full scope and severity of TFAW exploitation. By measuring abuse and exploitation through legal avenues for recourse, the Labour Law Approach misses the many instances of TFAW abuse that go unreported. Reforms to this approach are suggested; namely, to incorporate aspects of other frameworks aimed to understand labour exploitation and to utilize qualitative methods to further comprehend these experiences. Future research should employ qualitative methods that centre TFAWs as active agents in their resistance to workplace abuse and recommended policy solutions.
Consistent Energy-Based Atomistic/Continuum Coupling for Two-Body Potentials in One and Two Dimensions

description: This paper addresses the problem of consistent energy-based coupling of atomistic and continuum models of materials, limited to zero-temperature statics of simple crystals. It has been widely recognized that the most practical coupled methods exhibit large errors on the atomistic/continuum interface (which are often attributed to spurious forces called "ghost forces"). There are only few existing works that propose a coupling which is sufficiently accurate near the interface under certain limitations. In this paper a novel coupling that is free from "ghost forces" is proposed for a two-body interaction potential under the assumptions of either (i) one spatial dimension, or (ii) two spatial dimensions and piecewise affine finite elements for describing the continuum deformation. The performance of the proposed coupling is demonstrated with numerical experiments. The coupling strategy is based on judiciously defining the contributions of the atomistic bonds to the discrete and the continuum potential energy. The same method in one dimension has been independently developed and analyzed in Li and Luskin (arXiv:1007.2336).
