description: Many musical instruments, as for example woodwind instruments, flute or violins, are self-sustained oscillating systems, i.e. musician enacts as a continuous energy source to drive an oscillation in the passive resonator, the body of the instrument, by means of a nonlinear coupling. For single reed instruments like clarinet, there exists a minimal value of mouth pressure beyond which sound can appear. This paper deals with the analysis of this oscillation threshold, calculated using a modal decomposition of the resonator, in order to have a better comprehension of how reed characteristics, such as its strength and its damping, may influence the attack transient of notes.

description: The present paper is concerned with properties of multiple Schramm--Loewner evolutions (SLEs) labelled by a parameter $κ\in (0,8]$. Specifically, we consider the solution of the multiple Loewner equation driven by a time change of Dyson's Brownian motions in the non-colliding regime. Although it is often considered that several properties of the solution can be studied by means of commutation relations of SLEs and the absolute continuity, this method is available only in the case that the curves generated by commuting SLEs are separated. Beyond this restriction, it is not even obvious that the solution of the multiple Loewner equation generates multiple curves. To overcome this difficulty, we employ the coupling of Gaussian free fields and multiple SLEs. Consequently, we prove the longstanding conjecture that the solution indeed generates multiple continuous curves. Furthermore, these multiple curves are (i) simple disjoint curves when $κ\in (0,4]$, (ii) intersecting curves when $κ\in (4,8)$, and (iii) space-filling curves when $κ=8$.

description: The socioeconomic movement is an effort to better explain human behavior by combining insights of economists and sociologists. This paper contributes to the socioeconomic literature by including the influence of relationships, values, and social bonds in the neoclassical economic model by introducing social capital coefficients. The usefulness of the resulting social capital model is demonstrated theoretically in a two-firm cooperative model and tested empirically using data from a survey of students who allocate their time between individual and joint projects.

description: Vacuum expectation value of the energy-momentum tensor and the vacuum interaction forces are evaluated for a massive scalar field with general curvature coupling parameter satisfying Robin boundary conditions on two codimension one parallel branes embedded in background spacetime $AdS_{D_1+1}\times Σ$ with a warped internal space $Σ$. The vacuum energy-momentum tensor is presented as a sum of boundary-free, single brane induced, and interference parts. The latter is finite everywhere including the points on the branes and is exponentially small for large interbrane distances. Unlike to the purely AdS bulk, the part induced by a single brane, in addition to the distance from the brane, depends also on the position of the brane in the bulk. The asymptotic behavior of this part is investigated for the points near the brane and for the position of the brane close to the AdS horizon and AdS boundary. The vacuum forces acting on the branes are presented as a sum of the self-action and interaction terms. The interaction forces between the branes are finite for all nonzero interbrane distances and are investigated as functions of the brane positions and the length scale of the internal space. As an example the case $Σ=S^{D_2}$ is considered. An application to the higher dimensional generalization of the Randall-Sundrum brane model with arbitrary mass terms on the branes is discussed.

description: Quantum light-matter systems at strong coupling are notoriously challenging to analyze due to the need to include states with many excitations in every coupled mode. We propose a nonperturbative approach to analyze light-matter correlations at all interaction strengths. The key element of our approach is a unitary transformation that achieves asymptotic decoupling of light and matter degrees of freedom in the limit where light-matter interaction becomes the dominant energy scale. In the transformed frame, truncation of the matter/photon Hilbert space is increasingly well-justified at larger coupling, enabling one to systematically derive low-energy effective models, such as tight-binding Hamiltonians. We demonstrate the versatility of our approach by applying it to concrete models relevant to electrons in crystal potential and electric dipoles interacting with a cavity mode. A generalization to the case of spatially varying electromagnetic modes is also discussed.

description: In an era of rapid consolidation in banking, the effect of mergers on the availability of credit to agricultural businesses is unclear. Commercial bank mergers have profoundly altered the urban credit marketplace and are positioned to do the same for the agricultural credit marketplace. Adjustment models are estimated with data on independent bank consolidations from 1988 through 1995. The regression results bode well for agricultural lending if acquiring banks have larger concentrations of assets in agriculture than acquired banks. Conversely, if acquiring banks have smaller concentrations than acquired banks, acquisitions have a negative impact on agricultural lending. Since most acquiring banks have smaller agricultural loan concentrations than acquired banks, there is concern for agricultural lending. However, other lenders are likely to fill credit gaps that develop.
Construction of Quantum Field Theories with Factorizing S-Matrices
Creators: name: Lechner, Gandalf
Publisher: name: arXiv
Year: 2006
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: A new approach to the construction of interacting quantum field theories on two-dimensional Minkowski space is discussed. In this program, models are obtained from a prescribed factorizing S-matrix in two steps. At first, quantum fields which are localized in infinitely extended, wedge-shaped regions of Minkowski space are constructed explicitly. In the second step, local observables are analyzed with operator-algebraic techniques, in particular by using the modular nuclearity condition of Buchholz, d'Antoni and Longo. Besides a model-independent result regarding the Reeh-Schlieder property of the vacuum in this framework, an infinite class of quantum field theoretic models with non-trivial interaction is constructed. This construction completes a program initiated by Schroer in a large family of theories, a particular example being the Sinh-Gordon model. The crucial problem of establishing the existence of local observables in these models is solved by verifying the modular nuclearity condition, which here amounts to a condition on analytic properties of form factors of observables localized in wedge regions. It is shown that the constructed models solve the inverse scattering problem for the considered class of S-matrices. Moreover, a proof of asymptotic completeness is obtained by explicitly computing total sets of scattering states. The structure of these collision states is found to be in agreement with the heuristic formulae underlying the Zamolodchikov-Faddeev algebra.

The possible exchange of bath bosons between qubits gives rise to spatial and temporal correlations in the noise.

description: We carried out simulative investigations on a non-toxic, lead-free perovskite solar cell (PSC), where Cs2AgBiBr6, P3HT, ZnO nanorod, and C were utilized as the absorber layer, hole transport layer, electron transport layer, and back contact, respectively. At 600 nm optimum absorber thickness, the device achieved a maximum power conversion efficiency of 4.48%. The PSC operated optimally when the electron affinities were set at 3.3 eV and 4.6 eV for P3HT and ZnO nanorod, respectively. Moreover, the hole mobility and acceptor concentration of P3HT should be weighed during the choosing of appropriate doping additives and doping levels. Besides, the optimum back contact work function and absorber defect density were found to be 5.2 eV and 1E15 cm-3, respectively. We also observed the effect of radiative recombination rates and different charge transport layers on the device's performance. Overall, this study's simulation results will provide insightful guidance towards fabricating an environmentally benign PSC.

Subjects: Academic Journal of Science, Engineering and Technology

description: Analytical studies were carried out to isolate and identify common bacteria that affect beer produced from mass rice and white sorghum malts during fermentation. Rice and sorghum malts were used in the course of this research to produce beer using a commercial yeast (Saccharomyces cerevisiae). Worts were obtained by infusion mashing and analysed for their physicochemical properties before wort boiling and subsequent pitching of the yeast (Saccharomyces cerevisiae) to commence fermentation that lasted seven days. Isolation of bacteria was done by culturing the beer samples on Nutrient, MacConkey and De Man Rogosa and Sharpe (MRS) agar plates and incubated for 48 hours. Morphological and microscopic analysis were used to identify the bacterial isolates. Results of wort analysis gave original gravity (1.030 and 1.0320ρ), sugar (78.0 and 7.55)0Brix, pH (5.6 and 5.4) and viscosity (1.21 and 1.13) cP for the wort samples from sorghum and rice malts, respectively. The beer after analysis gave specific gravity (1.005 and 1.004)0r, sugar (1.03 and 1.29)0Brix, pH (4.0 and 4.1) and %alcohol (3.66 and 3.27) v/v. the total bacterial counts was 1.2x104 and 1.1x1047cfu/ml and the lactic acid bacterial count ranged from 1.3x104–1.2.x104cfu/ml for beer produced from rice and sorghum malts, respectively with no coliform count. The bacterial isolates identified included Streptococcus, Lactobacillus and Micrococcus species. This study confirmed the prevalence of contaminating bacteria on beer samples produced from rice and sorghum malts when fermentation is carelessly handled.

It is demonstrated that analyticity and the $N_c$ counting rule exclude the existence of $S$ matrix poles with ${\cal M}, Γ\sim O(1)$. Especially the properties of $σ$ and $f_0(980)$ with respect to the $1/N_c$ expansion are discussed. We point out that in general tetra-quark resonances do not exist.

Possible observational signatures in Large Hadron Collider (LHC) events are considered in the framework of the Arkani-Hamed-Dimopoulos-Dvali (ADD) braneworld model. Lower bounds on the value of the bulk cosmological constant required to produce visible effects are derived thanks to a dynamical Monte-Carlo simulation. This preliminary study has to be refined by the accurate computation of the greybody factors. It opens a new way to investigate the structure of non-asymptotically flat higher-dimensional spacetimes.

Electric Vehicle Routing and Charging/Discharging under Time-Variant Electricity Prices

Publisher: name: arXiv
Year: 2020
Subjects: subject: Optimization and Control (math.OC)

description: The integration of electric vehicles (EVs) with the energy grid has become an important area of research due to the increasing EV penetration in today's transportation systems. Under appropriate management of EV charging and discharging, the grid can currently satisfy the energy requirements of a considerable number of EVs. Furthermore, EVs can help enhance the reliability and stability of the energy grid through ancillary services such as energy storage. This paper proposes the EV routing problem with time windows under time-variant electricity prices (EVRPTW-TP) which optimizes the routing of an EV fleet that are delivering products to customers, jointly with the scheduling of the charging and discharging of the EVs from/to the grid. The proposed model is a multiperiod vehicle routing problem where EVs can stop at charging stations to either recharge their batteries or inject stored energy to the grid. Given the energy costs that vary based on time-of-use, the charging and discharging schedules of the EVs are optimized to benefit from the capability of storing energy by shifting energy demands from peak hours to off-peak hours when the energy price is lower. The vehicles can recover the energy costs and potentially realize profits by injecting energy back to the grid at high price periods. EVRPTW-TP is formulated as an optimization problem. A Lagrangian relaxation approach and a hybrid variable neighborhood search/tabu search heuristic are proposed to obtain high quality lower bounds and feasible solutions, respectively. Numerical experiments on instances from the literature are provided. The proposed heuristic is also evaluated on a case study of an EV fleet providing grocery delivery at the region of Kitchener-Waterloo in Ontario, Canada. Insights on the impacts of energy pricing, service time slots, range reduction in winter as well as fleet size are presented.
Novel G2 cell cycle checkpoint inhibitors and antimitotic agents isolated through two new HTS bioassays
Creators: name: Xu, Lin
Publisher: name: University of British Columbia
Year: 2009

description: The search for new pharmacologically active agents by screening natural sources such as microbial fermentations and plant extracts has led to the discovery of many clinically useful drugs that play a major role in the treatment of human diseases. Analogous to the investigation of terrestrial products, some recent studies of marine natural products have focused on their potential applications, particularly the treatment of human diseases, such as cancer. The goal of my thesis research was to discover structurally novel G2 cell cycle checkpoint inhibitors and antimitotic agents in natural product extracts. Active crude extracts were identified via high throughput bioassays for G2 checkpoint inhibitors and antimitotic agents. The assays were developed by our collaborator Michel Roberge and the details of the assays are introduced in the thesis. Several G2 checkpoint inhibitors were isolated and identified from extracts of marine organisms and plants. A new inhibitor pachyclavularolide F (18) was isolated from the soft coral Pachyclavularia violacea. Several inactive analogs including pachyclavulariolides A (43), B (44), C (45), D (46), E (47), and G (48) were also isolated from P. violacea. The previous known inhibitor staurosporine (10) and its new semisynthetic oxazolidone derivative (17) were discovered from a marine microorganism. The known metabolites aaptamine (12), isolated from the sponge Aaptos auberitoides and the diterpene lactones (19, 54, 55) from the tropical bush Parinari curatellifolia were found to show the G2 checkpoint inhibition. Using Dr. Roberge's high throughput antimitotic assay, the paclitaxel derivatives 10-deacetyltaxuyunnanine A (71) and 7-(β-xylosyl)-10-deacetyltaxol C (72) were isolated from the Southern American plant Ilex macrophylla. This work resulted in the discover of a new natural source for paclitaxel derivatives, and it also validated the accuracy and efficiency of the new antimitotic assay. My research on new metabolites from a marine sponge Xestospongia ingens guided by a traditional cytotoxicity bioassay led to several new ingenamine alkaloid derivatives, including ingenamines H (56), I (57), J (58), K (59), and L (60).

Analysis of our measurements within this framework indicates a simple model for the noise sources acting on the qubit. We discuss various methods to fight decoherence.

description: We investigate the visibility of the current and shot-noise correlations of electrical analogs of the optical Mach-Zehnder interferometer and the Hanbury Brown Twiss interferometer. The electrical analogs are discussed in conductors subject to high magnetic fields where electron motion is along edge states. The transport quantities are modulated with the help of an Aharonov-Bohm flux. We discuss the conductance (current) visibility and shot noise visibility as a function of temperature and applied voltage. Dephasing is introduced with the help of fictitious voltage probes. Comparison of these two interferometers is of interest since the Mach-Zehnder interferometer is an amplitude (single-particle) interferometer whereas the Hanbury Brown Twiss interferometer is an intensity (two-particle) interferometer. A direct comparison is only possible for the shot noise of the two interferometers. We find that the visibility of shot noise correlations of the Hanbury Brown Twiss interferometer as function of temperature, voltage or dephasing, is qualitatively similar to the visibility of the first harmonic of the shot noise correlation of the Mach-Zehnder interferometer. In contrast, the second harmonic of the shot noise visibility of the Mach-Zehnder interferometer decreases much more rapidly with increasing temperature, voltage or dephasing rate.

In particular an announced proof of the Theorem 1 (by Dziemiańczuk) from [1] announced in India -Kolkata- December 2007 is delivered here. Namely here and there we claim that any cobweb admissible sequence F is at the point product of primary cobweb admissible sequences taking values one and/or certain power of an appropriate primary number p. Here also an algorithm to produce the family of all cobweb-admissible sequences i.e. the Problem 1 from [1] i.e. one of several problems posed in source papers [2,3] is solved using the idea and methods implicitly present already in [4]

Proposed Specification for Bridge Paints
Creators: name: Havens, James H.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1960
Subjects: subject: Transportation Engineering

description: On July 30, 1958, two proposed bridge paint system specifications were submitted by this Division for Department consideration. Since that time, there have been several discussion sessions between various paint industry, representatives, members of the Department Specifications Committee, and J. H. Havens, Assistant Director of Research. Mr. Havens has been requested by the Specifications Committee to re-write one of the specifications, BASIC LEAD SILICO-CHROMATE, OIL-ALKYD PAINT SYSTEMS FOR IRON AND STEEL STRUCTURES (BRIDGES), and to prepare an additional specification covering, PHENOLIC RESIN PENETRATING LIQUID PAINT SYSTEM FOR IRON AND STEEL STRUCTURES (BRIDGES).

A Discussion on the Durability of Expanded Shale Aggregate for Exposed Concrete Structures (Bridges)
Creators: name: Havens, James H.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1960
Subjects: subject: Transportation Engineering

description: During the period between 1924 and 1934, in particular, numerous reinforced concrete bridges were built in Kentucky and elsewhere. Although many of them are still in service, they are some 30 years old and are showing the effects of time and weather. While it is true, of course, that they were constructed without the benefit of air-entrainment and without many present-day control practices, the influences of aggregate quality and freeze-thaw are usually apparent. The advent of the de-icing salt era, about 1940 and following World War II, introduced an additional deteriorating influence gnawing at old and new structures alike. The problem of maintaining and repairing older bridges is seriously compounded by the fact that newer bridges seem to have a relatively shorter maintenance-free life-expectancy because of the de-icing salt treatment.
QCD-supression by Black Hole Production at the LHC

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Possible consequences of the production of small black holes at the LHC for different scenarios with large extra dimensions are investigated. The effects from black hole production on some standard jet observables are examined, concentrating on the reduction of the QCD cross section. It is found that black hole production of partons interacting on a short enough distance indeed seem to generate a drastic drop in the QCD cross section. However from an experimental point of view this will in most cases be camouflaged by energetic radiation from the black holes.

description: This study estimates the price determinants of show quality quarter horses sold at auction. Several characteristics including genetic and physical traits, quality of pedigree, and performance record of the horse, as well as the horse's offspring, were found to significantly impact selling price. Sale order positively affected price and appears to be driven by buyers rather than intentional ordering of the horses. A common practice at horse auctions is for the seller to reject the final bid offered and buy back the horse. Model-predicted prices for these buy-back horses indicate they are not undervalued by the final bids, based on their characteristics.

subject: sustainability

description: An economic model of ground water salinization is developed. Starting from a full, high-quality aquifer, there is an initial extraction period, an intermediate waste disposal period, and a final drainage period. Drainage management is initially source control and reuse, but eventually culminates in evaporation basins and a system steady-state. This process occurs over long time scales but is consistent with historical observation. Efficiency is qualitatively similar to common property though quantitative magnitudes differ substantially. Regulatory pricing instruments are developed to support the efficient allocation. The system is not sustainable in that net returns generally decline through time until the steady-state.

description: The value, relevance, and efficacy of conducting and publishing research has been widely debated throughout the agricultural economics profession. On the one hand, some argue that the research process creates little value and directly competes with teaching/outreach output. On the other hand, others argue that research provides answers to important questions, improves human capital, and complements teaching/outreach activities. I argue that the research and publishing process develops human capital, improves the quality of teaching/outreach, reduces bias, generates new ideas, improves societal welfare, creates innovation, and is essential for public policy debate.

description: This study presents a method to determine efficient environmental targets at a watershed level. Efficient targets are devised by estimating abatement cost and cost of environmental damages and minimizing their sum. The method was applied to a case study of phosphorus pollution in a watershed in Oklahoma. Several cumulative scenarios with alternative abatement options were simulated and efficient targets were determined. As the number of abatement options at disposal to agricultural sources increased, their optimal abatement expanded relative to the abatement at the point source. Efficient targets were found to be dependent on the choice of policy that stimulates abatement.
A Fuchsian viewpoint on the weak null condition

Subjects: subject: Analysis of PDEs (math.AP)

description: We analyze systems of semilinear wave equations in $3+1$ dimensions whose associated asymptotic equation admit bounded solutions for suitably small choices of initial data. Under this special case of the weak null condition, which we refer to as the \textit{bounded weak null condition}, we prove the existence of solutions to these systems of wave equations on neighborhoods of spatial infinity under a small initial data assumption. Existence is established using the Fuchsian method. This method involves transforming the wave equations into a Fuchsian equation defined on a bounded spacetime region. The existence of solutions to the Fuchsian equation then follows from an application of the existence theory developed in \cite{BOOS:2020}. This, in turn, yields, by construction, solutions to the original system of wave equations on a neighborhood of spatial infinity.

description: Some consumers derive utility from using products produced with specific processes, such as environmentally friendly practices. Means of verifying these credence attributes, such as certification, are necessary for the market to function effectively. A substitute or complementary solution may exist when consumers perceive a relationship between a process attribute and other verifiable product attributes. We present a model where the level of search and experience attributes influences the likelihood of production of eco-friendly products. Our results suggest that the market success of eco-friendly food products requires a mix of environmental and other verifiable attributes that together signal credibility.

Material examined
ESTONIA • 1 spec.; Vormsi Island, Saxby shore; Kõrgessaare Formation, Vormsi Regional Stage; GIT 878-49.
Description
This specimen is a fragment of a body chamber and four chambers of the phragmocone with a nearly tubular circular conch with a diameter of 9.2–9.5 mm and an angle of expansion of ca 1°. The preserved part of the body chamber is 16 mm long, the septa are ca 1.8 mm apart, respectively (RCL = 0.19), and the septal foramen is eccentric with an RSP of 0.28. The septa are directly transverse. The conch surface is not preserved.
Remarks
This specimen can be compared with Isorthoceras sp. B, but its lower angle of expansion at smaller conch diameters indicates an even smaller adult size (ca 10 mm) of this species. The lack of external shell prohibits any species level determination. However, based on the small adult size, conch shape and siphuncular position the species can be related to I. junceum. Another small species known from Late Ordovician strata of Sweden, I. curvilineatum Kröger, 2013, differs in having a central siphuncle.
