description: "Half the money I spend on advertising is wasted; the trouble is I don't know which half."

 The words of John Wanamaker (1838-1922), a pioneer American marketer and advertiser, still hold true almost 100 years since they were spoken in the context of the ubiquitous banner advertising also termed as internet display advertising (IDA). Whilst IDA has become a major component of the internet advertising industry with an estimated size of US$ 56.5 billion (ZenithOptimedia, 2014) and a compounded annual growth rate of 21.5% (ZenithOptimedia, 2014), our understanding of how IDA works is fairly nascent. Despite thousands of advertisers utilising this platform to target billions of audiences worldwide, there is still a lack of clarity of how IDA really works. Specifically there is a gap in understanding the level of IDA impressions that are required to drive a specific goal. The blistering pace at which internet advertising has grown and evolved has contributed in a large part to a research gap that has stubbornly persisted. On one hand internet's constant evolution has spawned user journeys that are a complex tangle of advertising impressions, search clicks and website visits. On the other hand internet's exponential growth has led to constantly expanding data sets both in terms of volume and number of variables. This has led to an ongoing need to constantly update the findings and methods in order to understand how IDA works. Developments in clickstream technology that track complex user behaviour on the internet have provided an opportunity to further research in the area of determining optimal frequency level in IDA to drive marketing goals.

 This research seeks to assist researchers and practitioners in their quest to improve their understanding of IDA and internet advertising as a whole by uncovering a deeper understanding of the impact IDA impression frequency plays in driving marketing goals, especially online purchases. Further, the study analyses the moderating influence of consumers' characteristics and spacing of IDA impressions after controlling for a comprehensive set of factors related to media and seasonality. Lastly, the study uniquely utilises an easy to use but effective method that overcomes issues that plague clickstream data characterised by very large volume and low conversion rates. The clickstream data for this study was obtained from the ad-server log files from a large advertising agency based in Singapore. The use of such a data-set for this study is a significant step towards linking the world of information systems and marketing by making effective use of big data in developing optimal IDA impression frequency guidelines that will ultimately contribute towards improving the ROI of internet display advertising (IDA).

description: Anchor-bolt insertion is a peg-in-hole task performed in the construction field for holes in concrete. Efforts have been made to automate this task, but the variable lighting and hole surface conditions, as well as the requirements for short setup and task execution time make the automation challenging. In this study, we introduce a vision and proprioceptive data-driven robot control model for this task that is robust to challenging lighting and hole surface conditions. This model consists of a spatial attention point network (SAP) and a deep reinforcement learning (DRL) policy that are trained jointly end-to-end to control the robot. The model is trained in an offline manner, with a sample-efficient framework designed to reduce training time and minimize the reality gap when transferring the model to the physical world. Through evaluations with an industrial robot performing the task in 12 unknown holes, starting from 16 different initial positions, and under three different lighting conditions (two with misleading shadows), we demonstrate that SAP can generate relevant attention points of the image even in challenging lighting conditions. We also show that the proposed model enables task execution with higher success rate and shorter task completion time than various baselines. Due to the proposed model's high effectiveness even in severe lighting, initial positions, and hole conditions, and the offline training framework's high sample-efficiency and short training time, this approach can be easily applied to construction.

description: Cone holography is a codimension-$n$ doubly holographic model, which can be interpreted as the holographic dual of edge modes on defects. The initial model of cone holography is based on mixed boundary conditions. This paper formulates cone holography with Neumann boundary conditions, where the brane-localized gauge fields play an essential role. Firstly, we illustrate the main ideas in an AdS$_4$/CFT$_1$ toy model. We show that the $U(1)$ gauge field on the end-of-the-world brane can make the typical solution consistent with Neumann boundary conditions. Then, we generalize the discussions to general codimension-$n$ cone holography by employing brane-localized $p$-form gauge fields. We also investigate perturbative solutions and prove the mass spectrum of Kaluza-Klein gravitons is non-negative. Furthermore, we prove that cone holography obeys holographic $c$-theorem. Finally, inspired by the recently proposed chiral model in AdS/BCFT, we construct another type of cone holography with Neumann boundary conditions by applying massive vector (Proca) fields on the end-of-the-world brane.

description: Motivated by attempts to quantum simulate lattice models with continuous Abelian symmetries using discrete approximations, we study an extended-O(2) model in two dimensions that differs from the ordinary O(2) model by the addition of an explicit symmetry breaking term $-h_q\cos(qφ)$. Its coupling $h_q$ allows to smoothly interpolate between the O(2) model ($h_q=0$) and a $q$-state clock model ($h_q\rightarrow\infty$). In the latter case, a $q$-state clock model can also be defined for noninteger values of $q$. Thus, such a limit can also be considered as an analytic continuation of an ordinary $q$-state clock model to noninteger $q$. In previous work, we established the phase diagram for noninteger $q$ in the infinite coupling limit ($h_q\rightarrow\infty$). We showed that there is a second-order phase transition at low temperature and a crossover at high temperature. In this work, we seek to establish the phase diagram at finite values of the coupling using Monte Carlo and tensor methods. We show that for noninteger $q$, the second-order phase transition at low temperature and crossover at high temperature persist to finite coupling. For integer $q=2,3,4$, we know there is a second-order phase transition at infinite coupling (i.e. the well-known clock models). At finite coupling, we find that the critical exponents for $q=3,4$ vary with the coupling, and for $q=4$ the transition may turn into a BKT transition at small coupling. We comment on the similarities and differences of the phase diagrams with those of quantum simulators of the Abelian-Higgs model based on ladder-shaped arrays of Rydberg atoms.

description: The original slides including animations can be viewed here: https://osf.io/br8vx/ In The Netherlands, Open Science has been (and still is) a hot topic of conversation among academics, funding agencies, universities, and politicians. However, implementing open and transparent scholarly practices is easier said than done: not only it requires time to learn new skills and tools (e.g., for data management or code sharing), but the rewards associated with such practices are not immediately quantifiable. Consequently, adoption among scholars has been slow. The Open Science Communities (OSCs) aim to increase awareness and accelerate the adoption of open and transparent scholarly practices. Armed with entrepreneurial spirit and a healthy dose of stubbornness, coordinators and members of these communities organize lectures, infosessions, journal clubs, practical workshops, and informal gatherings discussing all aspects of open science, from preregistration of research proposals to open access publishing. Peer support is crucial not only for practical reasons (decentralization speeds up adoption), but also to show researchers that their colleagues value such efforts. Open Science Communities are now recognized and progressively institutionalized, as our experiences in Rotterdam and Utrecht can attest. Open Scholarship Community Galway opened a new exciting internationalization chapter. The ultimate goal is a global cultural shift in academia, from closeness and individualism towards transparency and collaboration. The presentation was part of the Open Scholarship Week 2020.

description: Maneuvering a spacecraft in the cislunar space is a complex problem, since it is highly perturbed by the gravitational influence of both the Earth and the Moon, and possibly also the Sun. Trajectories minimizing the needed fuel are generally preferred in order to decrease the mass of the payload. A classical method to constrain maneuvers is mathematically modelling them using the Two Point Boundary Value Problem (TPBVP), defining spacecraft positions at the start and end of the trajectory. Solutions to this problem can then be obtained with optimization techniques like the nonlinear least squares conjugated with the Theory of Functional Connections (TFC) to embed the constraints, which recently became an effective method for deducing orbit transfers. In this paper, we propose a tangential velocity (TV) type of constraints to design orbital maneuvers. We show that the technique presented in this paper can be used to transfer a spacecraft (e.g. from the Earth to the Moon) and perform rendezvous maneuvers (e.g. a swing-by with the Moon). In comparison with the TPBVP, solving the TV constraints via TFC offers several advantages, leading to a significant reduction in computational time. Hence, it proves to be an efficient technique to design these maneuvers.

description: Bound and unbound Frenkel-exciton pairs are essential transient precursors for a variety of photophysical and biochemical processes. In this work, we identify bound and unbound {Frenkel}-exciton complexes in an electron push-pull polymer semiconductor using coherent two-dimensional spectroscopy. We find that the dominant $A_{0-1}$ peak of the absorption vibronic progression is accompanied by a sub-peak, each dressed by distinct vibrational modes. By considering the Liouville pathways within a two-exciton model, the imbalanced cross peaks in one-quantum rephasing and non-rephasing spectra can be accounted for by the presence of pure biexcitons. The two-quantum non-rephasing spectra, on the other hand, provide direct evidence for unbound exciton pairs and biexcitons with dominantly attractive force. In addition, the spectral features of unbound exciton pairs show mixed absorptive and dispersive character, implying many-body interactions within the correlated {Frenkel}-exciton pairs. Our work offers novel perspectives on the rich photophysical processes in semiconductor polymers with the presence of Frenkel exciton complexes.

description: We present results from the ``Quasar hosts Unveiled by high Angular Resolution Techniques" (QUART) survey studying the Circumgalactic Medium (CGM) by observing rest-frame UV emission lines Ly$α$, C IV and He II around two radio-loud quasars, 3C 9 (z=2.02) and 4C 05.84 (z=2.32), using Keck Cosmic Web Imager (KCWI). We detect large-scale Ly$α$ nebulae around both quasars with projected diameters $\sim$ 100 kpc, with spatially resolved, embedded 15-30 kpc He II and C IV nebulae around both quasars as well as kinematically distinct He II and C IV nebulae at a physical separation of $\sim$ 15 kpc from both quasars. Observations of H$α$, H$β$, and [O III] emission using Keck MOSFIRE spectroscopically confirm that the Ly$α$ nebulae extend to companion galaxies and that these quasars are in a protogroup/protocluster environment. We confirm that the He II and C IV emission is kinematically and spatially coincident with the companion galaxies. We estimate the virial masses of the companion galaxies, their metallicities, and star formation rates, and investigate the sources of ionization. We measure the dynamical mass of the host dark matter halos and estimate that the dark matter halos of these systems will grow to a mass of 2 $\times 10^{14}$ M$_{\odot}$ (3C 9) and 2 $\times 10^{13}$ M$_{\odot}$ (4C 05.84) by z=0. The combined CGM and companion galaxies observations indicate Ly$α$ substructure can indicate the presence of companion galaxies in the CGM.

description: Optical microscopy is an indispensable tool in life sciences research, but conventional techniques require compromises between imaging parameters like speed, resolution, field-of-view, and phototoxicity. To overcome these limitations, data-driven microscopes incorporate feedback loops between data acquisition and analysis. This review overviews how machine learning enables automated image analysis to optimise microscopy in real-time. We first introduce key data-driven microscopy concepts and machine learning methods relevant to microscopy image analysis. Subsequently, we highlight pioneering works and recent advances in integrating machine learning into microscopy acquisition workflows, including optimising illumination, switching modalities and acquisition rates, and triggering targeted experiments. We then discuss the remaining challenges and future outlook. Overall, intelligent microscopes that can sense, analyse, and adapt promise to transform optical imaging by opening new experimental possibilities.

description: When trying to make sense of what is going on in the world and their personal lives, people often refer to scientific and religious explanations. Based on the pertinent literature, we introduce a novel self-report instrument that captures five types of how people subjectively conceptualize the science-religion relationship. In addition to examining the psychometric properties of the new instrument, we tested whether these five types of conceptualizations are ordered along a single continuum of conflict vs. compatibility. To test this, we ran and compared two unidimensional item response theory (IRT) models; a generalized partial credit model (GPCM) and a generalized graded unfolding model (GGUM), both in a German (total N = 2,920) and in a U.S. (N = 1,197) sample. We examined model fit statistics to determine the best-fitting model and examined measurement precision at the scale and the item levels. Finally, we tested measurement invariance across countries (i.e., Germany and the United States), as well as the discriminant, convergent, and criterion-related validity of our new instrument. Our results suggest that public perceptions of the relationship between science and religion are best captured by an unfolding response process (i.e. GGUM) and vary systematically across cultural contexts. In addition, U.S. participants perceived higher levels of conflict than their German counterparts. This research contributes to our theoretical understanding of science-religion perceptions and provides a validated measure for future cross-cultural research.
The interaction of flexible versus dedicated technology choice with financial risk management under financial constraints

description: This paper analyzes the impact of financial constraints in a capacity investment setting. We model a monopolist firm that decides on its technology choice (flexible versus dedicated) and capacity level under demand uncertainty. Differing from the majority of the stochastic capacity investment literature, we assume that the firm is budget-constrained both in the capacity investment and production stages, and that the production stage budget is stochastic. Our analysis contributes to the capacity investment literature by extending the theory of stochastic capacity investment to understand the impact of financial constraints, and by analyzing the impact of budget variability on the profitability of the firm. We demonstrate that budget variability is detrimental for the firm with either technology, thus the firm is better off by hedging the budget uncertainty through proper risk management. One of our main contributions is to analyze the impact of financial constraints on the flexible versus dedicated technology choice. We demonstrate that without production costs,a higher internal budget favors the flexible technology only when the fixed cost of the flexible technology is higher. With production costs in place, and in the absence of fixed cost difference, a higher internal budget favors the dedicated technology. This is because the total investment cost is higher with the dedicated technology.

Complete urban surface temperatures

description: An observation program using ground and airborne thermal infrared radiometers is used to estimate the surface temperature of urban areas, taking into account the total active surface area. The authors call this the complete urban surface temperature. This temperature is not restricted by the viewing biases inherent in remote sensors used to estimate surface temperature over rough surfaces such as cities. Two methods to estimate the complete surface temperature are presented. Results for three different land-use areas in the city of Vancouver, British Columbia, Canada, show significant differences exist between the complete, nadir, and off-nadir airborne estimates of urban surface temperature during daytime. For the sites and times studied, the complete surface temperature is shown to agree with airborne off-nadir estimates of the apparent surface temperature of the most shaded walls. Some implications of using the complete surface temperature to estimate screen level air temperature and to calculate surface sensible heat flux are given.

description: We consider the basic problem of a service firm that offers a product for rental to its customers for a fixed rental duration. Many firms prefer a predetermined rental duration to simplify the rental/return process and offer a fixed duration, such as two days, to appeal to most of its potential clients. As customer demand is normally stochastic and dependent on the rental rate, the firm has to determine not only its initial stock level but also the rental rate for its product to maximize its total profit. We present a two-stage discrete-time model to examine the rental problem. In stage one, the total time horizon is divided into N days and returned units are added to the stock at the beginning of each day. In stage two, the first day is divided into K time periods, each period is a small time interval Δt. At each time period, we dynamically adjust the rental rate according to the stock level inventory on hand and expected rental demand. We obtain the optimal pricing policy for this problem and show the existence and uniqueness of the optimal price policy. We demonstrate the expected optimal revenue is concave in the inventory level through numerical analysis. Meanwhile, we analyze the effects of the potential market size and price sensitive index by numerical studies. We find the optimal solution of the deterministic demand and show the optimal revenue is concave in the inventory on hand. Finally we show the deterministic case is the upper bound of stochastic problem and the periodical fixed price policy is asymptotical optimal as the inventory and the customer arrival go infinity.

description: Ferroelectric nematic liquid crystals are formed by achiral molecules with large dipole moments. Its three-dimensional orientational order is universally described as unidirectionally polar. We demonstrate that the ground state of ferroelectric nematic unconstrained by externally imposed alignment directions is chiral, with left- and right-hand twists of polarization. Although the helicoidal deformations and defect walls separating domains of opposite handedness increase the elastic energy, the twists reduce the electrostatic energy and become weaker when the material is doped with ions. The study shows that the polar orientational order of molecules could trigger chirality in the soft matter with no chemically induced chiral centers.

description: Understanding nanoscale mechanisms responsible for the recently discovered ferroelectric nematics can be helped by direct visualization of self-assembly of strongly polar molecules. Here we report on scanning tunneling microscopy (STM) studies of monomolecular layers of a ferroelectric nematic liquid crystal on a reconstructed Au(111) surface. The monolayers are obtained by deposition from a solution at ambient conditions. The adsorbed ferroelectric nematic molecules self-assemble into regular rows with tilted orientation, resembling a layered structure of a smectic C. Remarkably, each molecular dipole in this architecture is oriented along the same direction giving rise to polar ferroelectric ordering.
