description: We solve the sup-norm problem for spherical Hecke-Maass newforms of square-free level for the group GL(2) over a number field, with a power saving over the local geometric bound simultaneously in the eigenvalue and the level aspect. Our bounds feature a Weyl-type exponent in the level aspect, they reproduce or improve upon all known special cases, and over totally real fields they are as strong as the best known hybrid result over the rationals.

description: Let $ϕ$ be a spherical Hecke-Maass cusp form on the non-compact space $\mathrm{PGL}_3(\mathbb{Z})\backslash\mathrm{PGL}_3(\mathbb{R})$. We establish various pointwise upper bounds for $ϕ$ in terms of its Laplace eigenvalue $λ_ϕ$. These imply, for $ϕ$ arithmetically normalized and tempered at the archimedean place, the bound $\|ϕ\|_\infty\ll_ελ_ϕ^{39/40+ε}$ for the global sup-norm (without restriction to a compact subset). On the way, we derive a new uniform upper bound for the $\mathrm{GL}_3$ Jacquet-Whittaker function.

description: Today’s business landscape requires understanding the dynamic nature of the product life cycle (PLC) when making inventory decisions. This paper presented an integrated inventory-pricing model for a supply chain consisting of a single retailer, a pre-existing product manufacturer, and a new entrance product manufacturer. The model incorporated the PLC framework, encompassing the introduction-growth, maturity, and decline phases. In this competitive setting, the pre-existing product (PEP) has already progressed through part of its PLC when the new pro-environmental product (NPP) enters the market. To address the unique characteristics of each PLC phase, each manufacturer offers distinct incentive policies to the retailer in each phase. The demand for PEP is influenced by time and the progressively decreasing retail prices of both products, while the demand for NPP depends on time, retail prices, and the product’s greenness level. The results demonstrated that manufacturer incentive policies, including credit payments during the maturity phase, significantly increase profits for all three supply chain members. Moreover, extending the maturity phase of PEP and the introduction-growth and maturity phases of NPP enhances the retailer’s profitability.

description: Carbon materials have a range of properties such as high electrical conductivity, high specific surface area, and mechanical flexibility are relevant for electrochemical applications. Carbon materials are utilised in energy conversion-and-storage devices along with electrolytes of complementary properties. In this work, we study the interaction of highly concentrated electrolytes (ionic liquids) at a model carbon surface (circumcoronene) using density functional theory methods. Our results indicate the decisive role of the dispersion interactions that noticeably strengthen the circumcoronene-ion interaction. Also, we focus on the adsorption of halide anions as the electrolytes containing these ions are promising for practical use in supercapacitors and solar cells.

description: This study explores the ability of a large number of macroeconomic variables to forecast the mean, quantiles and density of key economic indicators. In the baseline case, we construct the forecasts using an autoregressive model. We then consider several general specifications that augment the time series model with macroeconomic information, either directly using the full set of predictors, through targeted-factors, targeted-predictors or forecast combinations. Our findings suggest that aggregating information across quantiles leads to improved estimates of the conditional mean. Overall, augmenting the autoregressive model with macroeconomic variables through methods that perform variable selection or account for non-linearities improves predictive performance. This increase in out-of-sample performance arises from the improved estimation of the lower and middle part of the distribution.
EXPLORING THE EFFECTS OF A CORTICOTROPIN RELEASING FACTOR (CRF) RECEPTOR ANTAGONIST ON HABIT EXPRESSION

description: Some individuals with alcohol use disorder (AUD) continue to drink because they have developed a habit in which they are not considering the consequences of their actions. Habitual actions persist despite changes in reward and are often studied using devaluation procedures. Stress hormones, such as corticotropin releasing factor (CRF), have been linked to AUD when examining binge-like drinking and withdrawal in rodents. Stress has been examined in the switch from goal-directed to habitual behavior, and CRF has often mimicked the effects of stress exposure. This study looked at the possible direct effects of CRF on habit expression in rats using an operant paradigm. Finding possible novel mechanisms of habit could create an avenue for future novel treatment options. Female and male Long Evans rats were trained on a variable interval schedule using sucrose as a reward. Rats then underwent devaluation procedures including both sensory-specific satiety and conditioned taste aversion (CTA) to test for habitual behaviors. Prior to an extinction session post-CTA, animals were treated with either 20 mg/kg R121919, a CRF1 receptor antagonist, or vehicle. A second extinction session was conducted where animals received the alternative treatment. Lever presses were recorded as a measure of goal-directed or habitual behavior. Sensory-specific satiety devaluation tests revealed that animals were not sensitive to devaluation. This was further supported by both post-CTA extinction sessions. R121919 had no effect on lever pressing in either devalued or valued groups. Further research is needed to explore how a CRF receptor antagonist may affect habit formation or the transition from goal-directed to habit behaviors. Future studies should also examine any possible interaction effects CRF may have with alcohol or stress on habitual behaviors.

We establish explicit estimates for various quantities related to $ϕ$ that are uniform in $λ_ϕ$. This includes uniforms bounds for spherical Whittaker functions on $\mathrm{GL}_n(\mathbb{R})$, uniform bounds for the global sup-norm of $ϕ$, and uniform bounds for the "essential support" of $ϕ$, i.e. the region outside which it decays exponentially. The proofs combine analytic and arithmetic tools.

description: This article analyzes the application of coaching technology in the educational process and its significance in the formation of professional competencies. The research results show that innovative pedagogical technologies, in particular, the coaching approach, are an effective tool for increasing the activity of the student learning process, strengthening their motivation, developing logical thinking and leadership skills. However, the lack of time and the complexity of individual assessment are noted as the main disadvantages of this technology. The author, justifying the need to introduce elements of coaching in the higher education system, recommends a review of the professional competencies of teachers and mentors. It also emphasizes the effective application of coaching approaches in the student achievement assessment system.

description: Higher derivative scalar field theory in curved space-time belongs to the GLPV theory coupled non-minimally to the Maxwell field is considered. We will show that the theory admits two independent exact de Sitter solutions in the FRW background, one driven by the cosmological constant and the other by the GLPV scalar field. The dynamical system analysis of the theory shows that these two exact solutions are stable fixed points. Also, cosmological perturbations over these solutions shows that the cosmological constant based solution is healthy at linear level but the GLPV based solution suffers from a gradient instability in the scalar sector. This proves that the cosmological constant is needed in the GLPV-Maxwell system in order to have a healthy de Sitter solution.

description: Consumers are inclined to make comparisons among brands. When brands with different popularity outsource to a common contract manufacturer (CM), it is highly prone to triggering consumer comparison behavior which can result in reference price effect. This article investigates how brands optimally choose sourcing strategy and competitive pricing strategy with consumers’ reference price effect. We focus on a supply chain consisting of one CM and two brands. Both brands can choose to insource or outsource to CM which has a cost advantage. Correspondingly, both brands are faced with a competitive pricing problem. We find that (i) if consumer’s acceptance of weak brand and the production cost is high, price competition is the fiercest in situation where both brands outsource to CM; otherwise, price competition is the fiercest in situation where weak brand exclusively outsources to CM. (ii) Either strong brand or weak brand prefers to exclusively outsource to CM while CM prefers the brands to simultaneously outsource. (iii) A strong reference price effect will always hurt strong brand but benefit weak brand no matter what reference price is considered. (iv) CM will be better (worse) off if strong (weak) brand’s retail price is regarded as the reference price.
title: The Liminal Text: Exploring the Perpetual Process of Becoming 
with particular reference to Samuel Selvon’s The Lonely Londoners and George Lamming’s The Emigrants
& Kitch: A Fictional Biography of The Calypsonian Lord Kitchener

Subjects: subject: Lord Kitchener, calypso, liminality, Lonely Londoners, George Lamming, Samuel Selvon, Emigrants, Windrush, Trinidad, Fictional Biography

description: This practice-as-research thesis is in two parts. The first, Kitch, is a fictional biography of Aldwyn
Roberts, popularly known as Lord Kitchener. Kitch represents the first biographical study of the
Trinidadian calypso icon, whose arrival in Britain onboard The Empire Windrush was famously
captured in Pathé footage. In the critical essay, contextualising Kitch, I argue that rite of passage
theory, in particular, liminality theory, as defined and developed by Victor W. Turner, offers a
valuable alternative to theories of hybridity and fragmentation hitherto applied to the postcolonial
Caribbean and its literature. To support this position I offer close readings of two iconic works of
postwar migratory fiction; George Lamming’s The Emigrants (1956) and Samuel Selvon’s The
Lonely Londoners (1956), showing how aspects of rite of passage and liminality theory illuminate
these novels.

My critical reflection on Kitch examines the marked absence of auto/biographical work on or
by calypso artists in ethnomusicology or mainstream publishing. This absence is disproportionate
both to the numerous studies of the calypso which approach the form homogeneously, at the
expense of its individual artists, and, to the socio-historical importance of the calypso to the
Caribbean and its disapora.

Since Kitch is a fictionalised biography, I provide a brief exploration of the genre by
drawing on the work of Michael Ondaatje and Earl Lovelace. My argument here is that the
multitudinous and liminal approach of Kitch offers a more plausible alternative to linear, single
narrator approaches since it mirrors both the process of research, and the manner in which a
community of non-hierarchical voices may contribute to the construction and memorialisation of a
calypsonian’s life.

description: We say that two graphs on the same vertex set are $G$-creating if their union (the union of their edges) contains $G$ as a subgraph. Let $H_n(G)$ be the maximum number of pairwise $G$-creating Hamiltonian paths of $K_n$. Cohen, Fachini and Körner proved \[n^{\frac{1}{2}n-o(n)}\leq H_n(C_4) \leq n^{\frac{3}{4}n+o(n)}.\] In this paper we close the superexponential gap between their lower and upper bounds by proving \[n^{\frac{1}{2}n-\frac{1}{2}\frac{n}{\log{n}}-O(1)}\leq H_n(C_4) \leq n^{\frac{1}{2}n+o\left(\frac{n}{\log{n}} \right)}.\] We also improve the previously established upper bounds on $H_n(C_{2k})$ for $k>3$, and we present a small improvement on the lower bound of Füredi, Kantor, Monti and Sinaimeri on the maximum number of so-called pairwise reversing permutations. One of our main tools is a theorem of Krivelevich, which roughly states that (certain kinds of) good expanders contain many Hamiltonian paths.

description: Mass spectrometry (MS) is a powerful and versatile analytical tool, especially for identification and analysis of complex mixtures. Coupling to high-performance liquid chromatography (HPLC) or gas chromatography (GC) provides additional dimension for mixture analysis. MS manipulates ionized analytes and separates them based on their mass-to-charge (m/z) ratios. MS is capable of providing molecular weight (MW) information by generating pseudo-molecular ions of the analytes. Detailed elemental compositions can be also obtained if high resolution MS is used. MS can also provide extensive structural information of the analyte ions. One of the most commonly used technique is tandem mass spectrometry (MSn). Ions of interest are isolated and subject to sequential reactions (reactions with other molecules or dissociation reactions) to generate product ions that can provide structural information. MS is also a powerful tool for generating and studying highly reactive reaction intermediates, such as organic polyradicals.
The research described in this dissertation mainly focuses on the generation and gas-phase reactivity studies of different organic biradicals. Their reactions with various organic reagents are studied, and the reactivity-controlling factors are discussed. For example, the reactivity of several substituted pyridine-based biradical cations with 2,6-topology are discussed (all with singlet ground states), and their special reactivity from their excited triplet states are illustrated. Besides, several quinoline-based biradicals and cyano-substituted pyridine-based para-benzyne cations are also discussed. Some of the radicals (or ions) described in this dissertation are generated for the first time, i.e. the quinoline-based oxenium cations. Their structural characterization and gas-phase reactivity toward some organic molecules are discussed in the dissertation. Further, an electrophilic anion, closo-[B12X11]- (X = Cl, Br) and its application in the activation of C-H and C-C bonds in hydrocarbon molecules are described in the dissertation.

Vers une utilisation durable des espèces

description: L’exploitation non durable des espèces est le premier facteur de diminution des populations pour plusieurs espèces.

L’exploitation des organismes n’est pas durable lorsque le prélèvement d’individus d’une population se fait au-delà du taux de renouvellement et de l’accroissement biologique de celle-ci, ou lorsque l’activité conduit à une dégradation de l’environnement qui perturbe cette espèce (par exemple, l’écotourisme intensif). Cette exploitation correspond à un service écosystémique d’approvisionnement – et aux contributions matérielles de la nature (dans la typologie de l’Ipbes) – lorsqu’elle vise à se nourrir, se vêtir, se chauffer ou se loger par exemple. Elle correspond à un service culturel – et aux contributions immatérielles de la nature – dans le cas d’activités récréatives ou spirituelles. Au niveau mondial, l’Ipbes estime qu’il s’agit de la 2e cause principale de perte de la biodiversité.

La pêche, la chasse, la cueillette et l’exploitation des forêts naturelles (par opposition aux plantations) sont les principales formes d’utilisation des espèces sauvages, entraînant un prélèvement dans la nature. Certaines activités sans prélèvement représentent également une forme d’utilisation.
4H-SiC Vertical Tri-gate Power MOSFETs Technology Development

Publisher: name: Purdue University Graduate School
Year: 2020
Subjects: Electrical engineering not elsewhere classified

description: Advances in power electronic systems, especially those in hybrid and electric automobiles and renewable power generation systems, demand high blocking voltage, fast switching performance and low thermal budget from power semiconductor devices. State-of-the--art, silicon based power semiconductor devices are limited by material properties in meeting these demands. Due to the relatively low critical electric field, the on-resistance of the devices is high, and increases significantly with blocking voltage. As a result, current silicon (Si) power MOSFETs rated at above 600 V suffer from unacceptably high conduction losses. Innovative designs, such as the insulated gate bipolar transistor (IGBT), have been developed which use conductivity modulation through the injection of minority carriers to reduce on-resistance. But the involvement of minority carriers gives rise to stored charge and a turn-off delay, dramatically increasing switching losses compared to unipolar devices. Silicon carbide (SiC), a wide band gap semiconductor provides an alternative to Si, and offers a 7x higher electric field strength, 2x higher saturation velocity, and 3x higher thermal conductivity. A thinner, more heavily doped drift region is required for a SiC power device for a particular voltage, which reduces on-resistance and power consumption. However, the channel resistance of SiC metal oxide semiconductor field effect transistors (MOSFETs) is high due to the poor quality of the dielectric-semiconductor interface. Thus the SiC MOSFET fails to live up to the full promise of the material. Minimization of the channel resistance is essential, especially for applications requiring blocking voltages under 1 kV, where this component dominates others. In this work, a novel tri-gate SiC MOSFET is proposed to address this issue. This new structure utilizes both the conventional horizontal surface as well as the sidewalls of a trench to increase the effective width of the channel without increasing the device area. With proper optimization, it should be possible to achieve 3x lower specific on-resistance compared to current SiC unipolar power devices.

description: The possible existence of naked singularities, hypothetical astrophysical objects, characterized by a gravitational singularity without an event horizon is still an open problem in present day astrophysics. From an observational point of view distinguishing between astrophysical black holes and naked singularities also represents a major challenge. One possible way of differentiating naked singularities from black holes is through the comparative study of thin accretion disks properties around these different types of compact objects. In the present paper we continue the comparative investigation of accretion disk properties around axially-symmetric rotating geometries in Brans-Dicke theory in the presence of a massless scalar field. The solution of the field equations contains the Kerr metric as a particular case, and, depending on the numerical values of the model parameter $γ$, has also solutions corresponding to non-trivial black holes and naked singularities, respectively. Due to the differences in the exterior geometries between black holes and Brans-Dicke-Kerr naked singularities, the thermodynamic and electromagnetic properties of the disks (energy flux, temperature distribution and equilibrium radiation spectrum) are different for these two classes of compact objects, consequently giving clear observational signatures that could discriminate between black holes and naked singularities.

description: We consider an $f(Q,T)$ type gravity model in which the scalar non-metricity $Q_{αμν}$ of the space-time is expressed in its standard Weyl form, and it is fully determined by a vector field $w_μ$. The field equations of the theory are obtained under the assumption of the vanishing of the total scalar curvature, a condition which is added into the gravitational action via a Lagrange multiplier. The gravitational field equations are obtained from a variational principle, and they explicitly depend on the scalar nonmetricity and on the Lagrange multiplier. The covariant divergence of the matter energy-momentum tensor is also determined, and it follows that the nonmetricity-matter coupling leads to the nonconservation of the energy and momentum. The energy and momentum balance equations are explicitly calculated, and the expressions of the energy source term and of the extra force are found. We investigate the cosmological implications of the theory, and we obtain the cosmological evolution equations for a flat, homogeneous and isotropic geometry, which generalize the Friedmann equations of standard general relativity. We consider several cosmological models by imposing some simple functional forms of the function $f(Q,T)$, and we compare the predictions of the theory with the standard $Λ$CDM model.

description: Stochastic gradient descent is one of the most common iterative algorithms used in machine learning and its convergence analysis is a rich area of research. Understanding its convergence properties can help inform what modifications of it to use in different settings. However, most theoretical results either assume convexity or only provide convergence results in mean. This paper, on the other hand, proves convergence bounds in high probability without assuming convexity. Assuming strong smoothness, we prove high probability convergence bounds in two settings: (1) assuming the Polyak-Łojasiewicz inequality and norm sub-Gaussian gradient noise and (2) assuming norm sub-Weibull gradient noise. In the second setting, as an intermediate step to proving convergence, we prove a sub-Weibull martingale difference sequence self-normalized concentration inequality of independent interest. It extends Freedman-type concentration beyond the sub-exponential threshold to heavier-tailed martingale difference sequences. We also provide a post-processing method that picks a single iterate with a provable convergence guarantee as opposed to the usual bound for the unknown best iterate. Our convergence result for sub-Weibull noise extends the regime where stochastic gradient descent has equal or better convergence guarantees than stochastic gradient descent with modifications such as clipping, momentum, and normalization.

Feudal Steering: Hierarchical Learning for Steering Angle Prediction

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: We consider the challenge of automated steering angle prediction for self driving cars using egocentric road images. In this work, we explore the use of feudal networks, used in hierarchical reinforcement learning (HRL), to devise a vehicle agent to predict steering angles from first person, dash-cam images of the Udacity driving dataset. Our method, Feudal Steering, is inspired by recent work in HRL consisting of a manager network and a worker network that operate on different temporal scales and have different goals. The manager works at a temporal scale that is relatively coarse compared to the worker and has a higher level, task-oriented goal space. Using feudal learning to divide the task into manager and worker sub-networks provides more accurate and robust prediction. Temporal abstraction in driving allows more complex primitives than the steering angle at a single time instance. Composite actions comprise a subroutine or skill that can be re-used throughout the driving sequence. The associated subroutine id is the manager network's goal, so that the manager seeks to succeed at the high level task (e.g. a sharp right turn, a slight right turn, moving straight in traffic, or moving straight unencumbered by traffic). The steering angle at a particular time instance is the worker network output which is regulated by the manager's high level task. We demonstrate state-of-the art steering angle prediction results on the Udacity dataset.

description: Side-channel analysis (SCA) is a prominent tool to break mathematically secure cryptographic engines, especially on resource-constrained devices. SCA attacks utilize physical leakage vectors like the power consumption, electromagnetic (EM) radiation, timing, cache hits/misses, that reduce the complexity of determining a secret key drastically, going from 2128 for brute force attacks to 212 for SCA in the case of AES-128. Additionally, EM SCA attacks can be performed non-invasively without any modifications to the target under attack, unlike power SCA. To develop defenses against EM SCA, designers must evaluate the cryptographic implementations against the most powerful side-channel attacks. In this work, systems and techniques that improve EM side-channel analysis have been explored, making it lower-cost and more accessible to the research community to develop better countermeasures against such attacks. The first chapter of this thesis presents SCNIFFER, a platform to perform efficient end-to-end EM SCA attacks. SCNIFFER introduces leakage localization – an often-overlooked step in EM attacks – into the loop of an attack. Following SCNIFFER, the second chapter presents a practical machine learning (ML) based EM SCA attack on AES-128. This attack addresses issues dealing with low signal-to-noise ratio (SNR) EM measurements, proposing training and pre-processing techniques to perform an efficient profiling attack. In the final chapter, methods for mapping from power to EM measurements, are analyzed, which can enable training a ML model with much lower number of encryption traces. Additionally, SCA evaluation of high-level synthesis (HLS) based cryptographic algorithms is performed, along with the study of futuristic neural encryption techniques.

description: The MSF Scientific Days is a series of one-day conferences that present research and innovations from MSF’s field projects. In 2017, MSF Scientific Days took place in London (UK; research and innovation days), New Delhi (India), and Blantyre (Malawi), with satellite events in Argentina and Australia. The events drew the participation of over 7000 people from 112 countries. Every year, we survey the corresponding authors of the previous year’s event to find out what happened next: did their work lead to changes in programmes or policies – ie, did the researchers perceive their studies had an impact? Here we present the findings of the survey for the research day in London.

description: We consider the geodesic deviation equation, describing the relative accelerations of nearby particles, and the Raychaudhuri equation, giving the evolution of the kinematical quantities associated with deformations (expansion, shear and rotation) in the Weyl type $f(Q,T)$ gravity, in which the nonmetricity $Q$ is represented in the standard Weyl form, fully determined by the Weyl vector, while $T$ represents the trace of the matter energy-momentum tensor. The effects of the Weyl geometry and of the extra force induced by the nonmetricity-matter coupling are explicitly taken into account. The Newtonian limit of the theory is investigated, and the generalized Poisson equation, containing correction terms coming from the Weyl geometry, and from the geometry matter coupling, is derived. As a physical application of the geodesic deviation equation the modifications of the tidal forces, due to the nonmetricity-matter coupling, are obtained in the weak field approximation. The tidal motion of test particles is directly influenced by the gradients of the extra force, and of the Weyl vector. As a concrete astrophysical example we obtain the expression of the Roche limit (the orbital distance at which a satellite begins to be tidally torn apart by the body it orbits) in the Weyl type $f(Q,T)$ gravity.

Privacy Preserving Systems With Crowd Blending

description: Over the years, the Internet has become a platform where individuals share their thoughts and personal information. In some cases, these content contain some damaging or sensitive information, which a malicious data collector can leverage to exploit the individual. Nevertheless, what people consider to be sensitive is a relative matter: it not only varies from one person to another but also changes through time. Therefore, it is hard to identify what content is considered sensitive or damaging, from the viewpoint of a malicious entity that does not target specific individuals, rather scavenges the data-sharing platforms to identify sensitive information as a whole. However, the actions that users take to change their privacy preferences or hide their information assists these malicious entities in discovering the sensitive content.
This thesis offers Crowd Blending techniques to create privacy-preserving systems while maintaining platform utility. In particular, we focus on two privacy tasks for two different data-sharing platforms— i) concealing content deletion on social media platforms and ii) concealing censored information in cryptocurrency blockchains. For the concealment of the content deletion problem, first, we survey the users of social platforms to understand their deletion privacy expectations. Second, based on the users’ needs, we propose two new privacy-preserving deletion mechanisms for the next generation of social platforms. Finally, we compare the effectiveness and usefulness of the proposed mechanisms with the current deployed ones through a user study survey. For the second problem of concealing censored information in cryptocurrencies, we present a provably secure stenography scheme using cryptocurrencies. We show the possibility of hiding censored information among transactions of cryptocurrencies.
