description: Several results in the existing literature establish Euclidean density theorems of the following strong type. These results claim that every set of positive upper Banach density in the Euclidean space of an appropriate dimension contains isometric copies of all sufficiently large elements of a prescribed family of finite point configurations. So far, all results of this type discussed linear isotropic dilates of a fixed point configuration. In this paper we initiate the study of analogous density theorems for families of point configurations generated by anisotropic dilations, i.e., families with power-type dependence on a single parameter interpreted as their size. More specifically, here we prove nonisotropic power-type generalizations of a result by Bourgain on vertices of a simplex, a result by Lyall and Magyar on vertices of a rectangular box, and a result on distance trees, which is a particular case of the treatise of distance graphs by Lyall and Magyar. Another source of motivation for this paper is providing additional evidence for the versatility of the approach stemming from the work of Cook, Magyar, and Pramanik and its modification used recently by Durcik and the present author. Finally, yet another purpose of this paper is to single out anisotropic multilinear singular integral operators associated with the above combinatorial problems, as they are interesting on their own.

description: Let a 1-d system of hyperbolic conservation laws, with two unknowns, be endowed with a convex entropy. We consider the family of small $BV$ functions which are global solutions of this equation. For any small $BV$ initial data, such global solutions are known to exist. Moreover, they are known to be unique among $BV$ solutions verifying either the so-called Tame Oscillation Condition, or the Bounded Variation Condition on space-like curves. In this paper, we show that these solutions are stable in a larger class of weak (and possibly not even $BV$) solutions of the system. This result extends the classical weak-strong uniqueness results which allow comparison to a smooth solution. Indeed our result extends these results to a weak-$BV$ uniqueness result, where only one of the solutions is supposed to be small $BV$, and the other solution can come from a large class. As a consequence of our result, the Tame Oscillation Condition, and the Bounded Variation Condition on space-like curves are not necessary for the uniqueness of solutions in the $BV$ theory, in the case of systems with 2 unknowns. The method is $L^2$ based. It builds up from the theory of a-contraction with shifts, where suitable weight functions $a$ are generated via the front tracking method.

Adiabatic theory of the polaron spectral function

Year: 2020
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: An analytic theory for the spectral function for electrons coupled with phonons is formulated in the adiabatic limit. In the case when the chemical potential is large and negative $μ\to -\infty$ the ground state does not have the adiabatic deformation and the spectral function is defined by the standard perturbation theory. In this limit we present the spectral function calculated up to fourth order in the electron-phonon coupling constant which satisfies the sum rules up to the 5th moment. In the case when the chemical potential is pinned at the polaron binding energy the spectral function is defined by the ground state with a nonzero adiabatic deformation. We calculate the spectral function with the finite polaron density in the adiabatic limit. We also demonstrate how the sum rules for higher moments may be evaluated in the adiabatic limit. Contrary to the case of zero polaron density the spectral function with the finite polaron concentration has some contributions which are characteristic for polarons.
The Green Masterplan: Crisis, State Transition and Urban Transformation in Post‐Genocide Rwanda

Year: 2020

description: This article connects nested narratives of change in post‐genocide Rwanda to examine how ideas of multi‐scaled crisis and programs of urban transformation take on greater developmental and distributional significance in a context of a complex political economy. Rwandan elites position the country as the ‘Singapore of Africa’ in their state developmental ambitions and environmental regulations, yet urban areas are reeling from the distributional impacts on services, land and affordable housing that these world‐class ambitions carry with them—particularly in the space of the capital, Kigali, and its peripheries. In this article I examine a concatenation of global development expertise, national programs for state transformation, and local planning consequences as urban areas in the country are remapped. What role do programs for urban transformation play in not only remapping the city, but in reconfiguring the political economy of the post‐conflict Rwandan nation‐state? I examine three themes that interconnect on state transformation through urbanization in Rwanda—international planning expertise, state greening and urban peripheralization—and argue for greater contextual attention to the implications of planning in post‐crisis geographies.

description: This article proposes a Universal Activation Function (UAF) that achieves near optimal performance in quantification, classification, and reinforcement learning (RL) problems. For any given problem, the optimization algorithms are able to evolve the UAF to a suitable activation function by tuning the UAF's parameters. For the CIFAR-10 classification and VGG-8, the UAF converges to the Mish like activation function, which has near optimal performance $F_{1} = 0.9017\pm0.0040$ when compared to other activation functions. For the quantification of simulated 9-gas mixtures in 30 dB signal-to-noise ratio (SNR) environments, the UAF converges to the identity function, which has near optimal root mean square error of $0.4888 \pm 0.0032$ $μM$. In the BipedalWalker-v2 RL dataset, the UAF achieves the 250 reward in $961 \pm 193$ epochs, which proves that the UAF converges in the lowest number of epochs. Furthermore, the UAF converges to a new activation function in the BipedalWalker-v2 RL dataset.

description: Kanye's debut trilogy of music- The College Dropout (2004), Late Registration (2005), and Graduation (2007) - modeled his ascension to the pinnacle of Hip Hop on truancy, a turning away from America's expected path of formal education. Black folks enter professional machineries of all sorts to make it up and over mountains of struggle, but once enduring the fires of training, whether in College, or in other networks, what awaits us on the other side of financial and commercial success can resemble more of a nightmare than a dream - a dark twisted fantasy. The symphonic feel of "Gone," supplicated by powerful lines from Cam'ron and Consequence, concludes with Kanye, lifted by strings, admitting his consideration to leave the rap game behind: "I'm ahead of my time, sometimes years out / So the powers that be won't let me get my ideas out / And that make me wanna get my advance out / And move to Oklahoma and just live at my aunt's house / Yeah, I romance the thought of leaving it all behind / Kanye step away from the lime / Light." [...]he realizes that assuming the role of a sensei in the rap game would be contributing to the mechanistic production of replaceable Hip Hop artists, and also depriving the world of his irreplaceable talent.

description: Although the theory of density evolution in maps and ordinary differential equations is well developed, the situation is far from satisfactory in continuous time systems with delay. This paper reviews some of the work that has been done numerically and the interesting dynamics that have emerged, and the largely unsuccessful attempts that have been made to analytically treat the evolution of densities in differential delay equations. We also present a new approach to the problem and illustrate it with a simple example.

research data management

description: The University of Vienna, Austria, supports its researchers in managing their research data in various ways. In autumn 2021, the research data management (RDM) policy was adopted. It codifies RDM support and clarifies responsibilities and opportunities for the institution and the researchers. Summer 2022 saw the establishment of a data stewardship programme. It is based on the "data steward network" model developed in the FAIR Data Austria project: There is one coordinator at the University Library and embedded data steward:esse:s at faculties/centres – in addition to the central services that are offered by various departments and coordinated by a university-wide strategy board. Two faculties and one centre participate in the pilot phase set on three years. Data steward:esse:s – in contrast to the data managers in the central services – are the central go-to persons with discipline-specific know-how and have a bridging function between the people who use RDM services with those who design and develop them. The first faculty to employ a data steward:ess was the Faculty of Philological and Cultural studies. Being the largest faculty of the university, it has about 800 researchers in fourteen departments of philologies and area studies. As part of the humanities, the faculty addresses the world’s cultural heritage in its material and immaterial form – languages, literature, music, religious practices, as well as artefacts and media of every type – and has a strong focus on Digital Humanities. The poster reports on the experiences as a data stewardess in the humanities - the first of its kind in Austria – and addresses the following aspects: specific requirements of humanities scholars establishing the role within the faculty possible differences between being a data steward:ess in the humanities and having this role in other disciplines

description: This paper aims to share the use of Tracker a free open source video analysis and modeling tool that is increasingly used as a pedagogical tool for the effective learning and teaching of Physics for Grade 9 Secondary 3 students in Singapore schools to make physics relevant to the real world. We discuss the pedagogical use of Tracker, guided by the Framework for K-12 Science Education by National Research Council, USA to help students to be more like scientists. For a period of 6 to 10 weeks, students use a video analysis coupled with the 8 practices of sciences such as 1. Ask question, 2. Use models, 3. Plan and carry out investigation, 4. Analyse and interpret data, 5. Use mathematical and computational thinking, 6. Construct explanations, 7. Argue from evidence and 8. Communicate information. This papers focus in on discussing some of the performance task design ideas such as 3.1 flip video, 3.2 starting with simple classroom activities, 3.3 primer science activity, 3.4 integrative dynamics and kinematics lesson flow using Tracker progressing from video analysis to video modeling, 3.5 motivating performance task, 3.6 assessment rubrics and lastly 3.7 close mentorship. Initial research findings using pre and post perception survey, triangulated with student interviews suggest an increased level of students enjoyment. Most importantly, the artefacts of the students performance task in terms of the research report and Tracker .TRZ files, further suggest that the use of the Tracker for performance tasks, guided by the Framework for K-12 Science Education by National Research Council, USA, can be an innovative way to mentor authentic and meaningful learning that empowers students to be more like scientists as defined in the K-12 Science Education Framework in classrooms.

description: We consider the symmetric exclusion process on the $d$-dimensional lattice with translational invariant and ergodic initial data. It is then known that as $t$ diverges the distribution of the process at time $t$ converges to a Bernoulli product measure. Assuming a summable decay of correlations of the initial data, we prove a quantitative version of this convergence by obtaining an explicit bound on the Ornstein $\bar d$-distance. The proof is based on the analysis of a two species exclusion process with annihilation.

description: Excerpts from the report Summary: Manufacturers of sweetened dairy products used about 4.7 percent of the total quantity of sugar, corn sirup, and dextrose delivered to consumers in the United States in 1961. Smaller quantities of noncaloric sweeteners (principally saccharin and sucaryl) and sorbitol were used in producing various dietetic dairy products. The principal dairy products for which sweeteners are important are ice cream, other frozen desserts, and sweetened condensed milk. The production of frozen desserts, including ice cream, has been increasing in the United States since 1952, but the output of sweetened condensed milk has declined. The manufacture of ice cream tends to be concentrated near centers of population because of the expense of transporting it long distances. Plants producing sweetened condensed milk are mostly situated in areas of heavy milk production, since it is less expensive to transport the manufactured product than fresh milk. From 1952 to 1961, the use of sweeteners (sugar, dextrose, and corn sirup) in dairy products has increased at an average rate of about 18,000 tons, or 4.7 percent a year. The use of corn sirup in sweetened dairy products increased from 1952 through 1961 at an average rate of about 5,000 tons, 12.5 percent per year, as compared with 14,000 tons or 4.0 percent, for sugar. The use of dextrose declined at an average rate of about 6.7 percent a year.
An upper limit on the scale of new physics phenomena from rising cross sections in high multiplicity Higgs and vector boson events

description: In very high energy scattering events production of multiple Higgs and electroweak gauge bosons becomes possible. Indeed the perturbative cross section for these processes grows with increasing energy, eventually violating perturbative unitarity. In addition to perturbative unitarity we also examine constraints on high multiplicity processes arising from experimentally measured quantities. These include the shape of the Z-peak and upper limits on scattering cross sections of cosmic rays. We find that the rate of high multiplicity electroweak processes will exceed these upper limits at energies not significantly above what can be currently tested experimentally. This leaves two options: 1) The electroweak sector becomes truly non-perturbative in this regime or 2) Additional physics beyond the Standard Model is needed. In both cases novel physics phenomena must set in before these energies are reached. Based on the measured Higgs mass we estimate the critical energy to be in the range of $10^3$ TeV but we also point out that it can potentially be significantly less than that.

description: In this paper, we present LookOut, a novel autonomy system that perceives the environment, predicts a diverse set of futures of how the scene might unroll and estimates the trajectory of the SDV by optimizing a set of contingency plans over these future realizations. In particular, we learn a diverse joint distribution over multi-agent future trajectories in a traffic scene that covers a wide range of future modes with high sample efficiency while leveraging the expressive power of generative models. Unlike previous work in diverse motion forecasting, our diversity objective explicitly rewards sampling future scenarios that require distinct reactions from the self-driving vehicle for improved safety. Our contingency planner then finds comfortable and non-conservative trajectories that ensure safe reactions to a wide range of future scenarios. Through extensive evaluations, we show that our model demonstrates significantly more diverse and sample-efficient motion forecasting in a large-scale self-driving dataset as well as safer and less-conservative motion plans in long-term closed-loop simulations when compared to current state-of-the-art models.

description: We consider the general case of an accelerating, expanding and shearing model of a radiating relativistic star using Lie symmetries. We obtain the Lie symmetry generators that leave the equation for the junction condition invariant, and find the Lie algebra corresponding to the optimal system of the symmetries. The symmetries in the optimal system allow us to transform the boundary condition to ordinary differential equations. The various cases for which the resulting systems of equations can be solved are identified. For each of these cases the boundary condition is integrated and the gravitational potentials are found explicitly. A particular group invariant solution produces a class of models which contains Euclidean stars as a special case. Our generalized model satisfies a linear equation of state in general. We thus establish a group theoretic basis for our generalized model with an equation of state. By considering a particular example we show that the weak, dominant and strong energy conditions are satisfied.

description: The electric dipole strength in 120Sn has been extracted from proton inelastic scattering experiments at E_p = 295 MeV and at forward angles including 0 degree. Below neutron threshoild it differs from the results of a 120Sn(gamma,gamma') experiment and peaks at an excitation energy of 8.3 MeV. The total strength corresponds to 2.3(2)% of the energy-weighted sum rule and is more than three times larger than what is observed with the (gamma,gamma') reaction. This implies a strong fragmentation of the E1 strength and/or small ground state branching ratios of the excited 1- states.

Cultivating Creativity: A Seed Library in the Academic Library Makerspace

Year: 2022

description: The emergence of one unique type of library, the seed library, is a growing trend in the library world: these collections of freely-available, “lendable” seeds may serve a variety of purposes, from preserving biodiversity to supporting home gardening communities. In the context of an academic library, they may serve as educational resources and outreach tools. The first seed library at the University of North Carolina at Chapel Hill was launched in spring 2022, and is housed in the Kenan Science Library Makerspace. With a collection featuring native North Carolina plants and other popular varieties, it lives in a retired card catalog. This poster will outline how seed libraries work, the process of starting this one, and how the Seed Library may be used to build connections and complement other hands-on resources in a science library. The objective of this project was to create a new resource that would both fit alongside existing university tools and initiatives, and help the science library connect with the rest of UNC’s campus and surrounding community. Preparation for launching the Seed Library consisted of background research, budgeting, planning, and acquiring and organizing materials, and promotion. The launch event had a high turnout and the Seed Library has experienced steady use ever since. We conclude that the Seed Library is a beneficial addition to our science library and its makerspace, and recommend that other libraries seeking to start one research their local area’s native plant species, connect with related organizations, and develop a promotion plan.

description: Due to the dominant position of deep learning (mostly deep neural networks) in various artificial intelligence applications, recently, ensemble learning based on deep neural networks (ensemble deep learning) has shown significant performances in improving the generalization of learning system. However, since modern deep neural networks usually have millions to billions of parameters, the time and space overheads for training multiple base deep learners and testing with the ensemble deep learner are far greater than that of traditional ensemble learning. Though several algorithms of fast ensemble deep learning have been proposed to promote the deployment of ensemble deep learning in some applications, further advances still need to be made for many applications in specific fields, where the developing time and computing resources are usually restricted or the data to be processed is of large dimensionality. An urgent problem needs to be solved is how to take the significant advantages of ensemble deep learning while reduce the required expenses so that many more applications in specific fields can benefit from it. For the alleviation of this problem, it is essential to know about how ensemble learning has developed under the era of deep learning. Thus, in this article, we present fundamental discussions focusing on data analyses of published works, methodologies, recent advances and unattainability of traditional ensemble learning and ensemble deep learning. We hope this article will be helpful to realize the intrinsic problems and technical challenges faced by future developments of ensemble learning under the era of deep learning.

description: In this work we perform the symmetry classification of the Klein Gordon equation in Bianchi I spacetime. We apply a geometric method which relates the Lie symmetries of the Klein Gordon equation with the conformal algebra of the underlying geometry. Furthermore, we prove that the Lie symmetries which follow from the conformal algebra are also and Noether symmetries for the Klein Gordon equation. We use these resutls in order to determine all the potentials in which the Klein Gordon admits Lie and Noether symmetries. Due to the large number of cases and for easy reference the results are presented in the form of tables. For some of the potentials we use the Lie admitted symmetries to determine the corresponding invariant solution of the Klein Gordon equation. Finally, we show that the results also solve the problem of classification of Lie/Noether point symmetries of the wave equation in Bianchi I spacetime and can be used for the determination of invariant solutions of the wave equation.

description: Peatlands are excellent foci of study due to their ability to act as archives of palaeoecological and archaeological proxy data, as the organic materials which constitute such data do not readily decompose within these waterlogged and acidic environments. Proxy data can be analyzed to discern how peatlands came to form through internal and external processes. Both natural and cultural (i.e., anthropogenic) forces are important external influences upon peatland formation. This study seeks to discern how a peat bog area at the archaeological site of L’Anse aux Meadows, Newfoundland formed as a result of natural successional processes and anthropogenic disturbance. This is accomplished through the use of a high temporal resolution (sub-centimetre) plant macrofossil analysis and radiocarbon age-depth modelling undertaken on a monolith (4A800B3-6) retrieved from a peat bog close to the main settlement terrace at the site. Through the application of this method, it is found that human-mediated disturbance (fire and trampling) and biophysical drivers (climate) each played a role in forming the peat sequence. Several different possibilities are offered for which particular cultural groups might be behind the disturbances in the peatland—which include the Norse but also Indigenous groups.

description: With disks and networks providing gigabytes per second, parsing decimal numbers from strings becomes a bottleneck. We consider the problem of parsing decimal numbers to the nearest binary floating-point value. The general problem requires variable-precision arithmetic. However, we need at most 17 digits to represent 64-bit standard floating-point numbers (IEEE 754). Thus we can represent the decimal significand with a single 64-bit word. By combining the significand and precomputed tables, we can compute the nearest floating-point number using as few as one or two 64-bit multiplications. Our implementation can be several times faster than conventional functions present in standard C libraries on modern 64-bit systems (Intel, AMD, ARM and POWER9). Our work is available as open source software used by major systems such as Apache Arrow and Yandex ClickHouse. The Go standard library has adopted a version of our approach.

description: Spectrunculus Jordan and Thompson, 1914
Giant Cuskeel
 Spectrunculus Jordan and Thompson, 1914: 301 (type species by monotypy S. radcliffei Jordan and Thompson, 1914).
 Parabassogigas Nybelin, 1957: 298 (type species by original designation Sirembo grandis G unther €, 1877).
 Diagnosis.— The genus Spectrunculus differs from all other ophidiid genera in the combination of the following characters: dorsal-fin rays 121–148; anal-fin rays 91–112; total vertebrae 72–88; pectoral-fin rays 24–31; head short, 4.2 to 5.9 times in SL and 1.75 to 2.89 times in preanal distance; head robust with rounded snout and with several pores above and below eyes, mouth subterminal, upper jaw extending well behind eye. Teeth minute, blunt and robust, vomer roughly triangular or rhombic shaped. Anterior nostril with a thick, fleshy raised rim, posterior nostril larger, a mere hole or slit close to eye. Opercular spine strong. Head and body completely covered by small oval scales. Eyes shorter than snout, 5.5 or more times in HL; long rakers on anterior gill arch 7–10; two median basibranchial tooth patches; pelvic fins placed below preopercle; otolith ostium and sulcus well developed; color of head and body uniformly pale creamy or whitish, light or dark brown (rarely pale with dark speckles or rings); unpaired fins often dark when fresh or recently collected; dark pigmentation may not be retained with longer-term preservation.
 Remarks.— Four valid species with maximum sizes of 60 to 130 cm SL (¼ ca. 65 to 140 cm TL) distributed in various parts of the major oceans (for details see species accounts below). Larger juveniles, subadults, and adults occur at or close to deep bathyal and abyssal bottoms (depth range ca. 1000 to at least 4255 m), mostly caught by bottom longlining or trawling or photographed in baited landers; larvae and small juveniles are pelagic (Ambrose, 1996). Considering their large size and relatively common occurrence in distinct areas, species of Spectrunculus may play an important ecological role in deep-sea ecosystems (Uiblein et al., 2008). No reported commercial value.

description: When circuits are set up and dismantled dynamically in elastic optical networks, spectrum tends to become fragmented in the fiber links. The fragmentation limits the available path choices and may lead to significant blocking of connection requests. There are two types of fragmentation in the network spectrum in the links due to contiguity constraints and over the paths due to continuity. Study of fragmentation and its management is essential to operate the networks efficiently. This paper proposes a vectored fragmentation metric for characterizing the fragmentation, which covers both types of fragmentation. We discuss the characteristics of this metric in both transient and steady-state of the dynamic network. We also test the proposed metric for connection requests granularity range, arrival rates and holding times, to establish functionality of this metric. We also compare the link-based fragmentation metric with our Vectored Fragmentation Metric to understand the better representation.

description: We have developed an efficient numerical method to investigate light scattering from plasmonic nanospheres on a substrate covered by a shell, based on the half-space Greens function approach. We use this method to study optical scattering from DNA molecules attached to metallic nanoparticles on a substrate and compare with experiment. We obtain fairly good agreement between theoretical predictions and the measured ellipsometric spectra. The metallic nanoparticles were used to detect the binding with DNA molecules in a microfluidic setup via spectroscopic ellipsometry (SE), and a detectable change in ellipsometric spectra was found when DNA molecules are captured on Au nanoparticles surface. Our theoretical simulation indicates that the coverage of Au nanosphere by a submonolayer of DNA molecules, which is modeled by a thin layer of dielectric material, can indeed lead to a small but detectable change in ellipsometric spectra. Our studies demonstrated the ultra-sensitive capability of SE for sensing submonolayer coverage of DNA molecules on Au nanospheres.

description: The popularity of 3D printers in libraries is growing. The COVID-19 pandemic caused the temporary closure of many of UNC-CH’s library locations, and thus the temporary transition of many library services to remote formats. The Kenan Science Library Makerspace at UNC offers a 3D printing and consultation service. By reimagining the workflow, for example with contactless pickup, the KSL has continued to offer it. The poster examines the operation of the Kenan Science Library Makerspace’s 3D printing service in the remote environment by analyzing usage data over time. The poster highlights steps to access the service digitally and highlights trends, with comparison of data collected before and during the pandemic. It also includes ideas for future research exploring remote makerspace services at UNC-Chapel Hill.

description: One of the most efficient methods for model compression is hint distillation, where the student model is injected with information (hints) from several different layers of the teacher model. Although the selection of hint points can drastically alter the compression performance, conventional distillation approaches overlook this fact and use the same hint points as in the early studies. Therefore, we propose a clustering based hint selection methodology, where the layers of teacher model are clustered with respect to several metrics and the cluster centers are used as the hint points. Our method is applicable for any student network, once it is applied on a chosen teacher network. The proposed approach is validated in CIFAR-100 and ImageNet datasets, using various teacher-student pairs and numerous hint distillation methods. Our results show that hint points selected by our algorithm results in superior compression performance compared to state-of-the-art knowledge distillation algorithms on the same student models and datasets.

Montaigne's Passions and Lipsian Subjects

description: Especially as the violence of numerous wars intensified toward the end of the sixteenth century, in the form of Neostoicism European intellectual interest in the emotions and passions turned to means of controlling them, to applying the will to dominating the self. One of the inaugural and widely defining texts of Neostoicism, Justus Lipsius’s 1584 De constantia, focuses on the passions not so much by theorizing them as by taking their affective and effective force as a given: through persuasive argumentation and invocation of ancient authority, Lipsius demonstrates both the necessity of so exercising the will and the capacity to do so. He couldn’t make it clearer that his purpose is to educate people to bear the hardships of war when it ravages their country, threatens their family and property, and devastates their peace of mind. His intended audience is not simply a wise elite, as Jacqueline Lagrée signals, since from the title of his precursor Seneca’s treatment of the subject, De constantia sapientis, he doesn’t include the word sapientis. This expansion of the public whom Lipsius invites to cultivate the virtue of constancy is, as I will show, important to his book’s political purpose.

description: Excerpts from report Summary: The beverage industry (soft drinks, malt, malt liquors, distilled liquors, flavorings) used 13.5 percent of all the sugar consumed in the United States and one-fourth of that delivered to industrial users in the United States in 1961. This was more than was delivered to any other industry. Beverage producers also used relatively small amounts of dextrose and corn sirup and increasing amounts of noncaloric sweeteners. Manufacturers of soft drinks are the largest users of sugar, followed by the producers of flavorings. However, soft drink manufacturers are the largest customers of the flavoring industry so that much of the sugar delivered to the flavoring industry reaches consumers in the form of a soft drink. Most of the corn sirup and dextrose delivered to the beverage industry is used as part of the fermentation material in the production of beer. The consumption of sugar by the beverage industry has been increasing since 1952 at a rate of about 49,000 tons per year. Deliveries of corn, sirup have increased about 3,200 tons per year, while those for dextrose declined from 1952 to 1959 and then increased to about the 1952 level. The percentage rate of increase in the use of corn sirup was more than twice that for sugar, but, the total quantity delivered in 1961 was less than 4 percent of the quantity of sugar delivered.
