description: This paper introduces a unifying physical framework based on the Mass–Energy Gradient (MEG) model, demonstrating that all stable structures in the universe—from electrons and phase transitions to stars, neutron stars, and galaxy clusters—occupy discrete rungs on a single harmonic ladder anchored by hydrogen. Each rung corresponds to a quantized energy-density gradient (EDG), with spacing governed by a purely geometric constant. The theory reproduces key gravitational phenomena without dark matter, terminates the lepton family naturally, and predicts quantized mass thresholds for compact objects. Strikingly, phase anomalies such as helium’s missing solid and the 2.5–5 M☉ compact-object mass gap are shown to mirror each other across scales as skipped ladder rungs. All derivations are based on EDG steepness rather than spacetime curvature, making this framework a fully metric-free alternative to general relativity and quantum mechanics in the domains it addresses. The paper concludes with falsifiable predictions and an observational roadmap for validating or refuting the ladder structure using current and near-future data (DESI, LIGO, NICER, Gaia).

description: We present a novel approach for high-order accurate numerical differentiation on unstructured meshes of quadrilateral elements. To differentiate a given function, an auxiliary function with greater smoothness properties is defined which when differentiated provides the derivatives of the original function. The method generalises traditional finite difference methods to meshes of arbitrary topology in any number of dimensions for any order of derivative and accuracy. We demonstrate the accuracy of the numerical scheme using dual quadrilateral meshes and a refinement method based on subdivision surfaces. The scheme is applied to the solution of a range of partial differential equations, including both linear and nonlinear, second and fourth order equations, and a time-dependent first order equation.

description: Background Point-of-care ultrasound (POCUS) is a growing part of internal medicine training programs. Dedicated POCUS rotations are emerging as a particularly effective tool in POCUS training, allowing for longitudinal learning and emphasizing both psychomotor skills and the nuances of clinical integration. In this descriptive paper, we set out to review the state of POCUS rotations in Canadian Internal Medicine training programs. Results We identify five programs currently offering a POCUS rotation. These rotations are offered over two to thirteen blocks each year, run over one to four weeks and support one to four learners. Across all programs, these rotations are set up as a consultative service that offers POCUS consultation to general internal medicine inpatients, with some extension of scope to the hospitalist service or surgical subspecialties. The funding model for the preceptors of these rotations is predominantly fee-for-service using consultation codes, in addition to concomitant clinical work to supplement income. All but one program has access to hospital-based archiving of POCUS exams. Preceptors dedicate ten to fifty hours to the rotation each week and ensure that all trainee exams are reviewed and documented in the patient’s medical records in the form of a consultation note. Two of the five programs also support a POCUS fellowship. Only two out of five programs have established learner policies. All programs rely on In-Training Evaluation Reports to provide trainee feedback on their performance during the rotation. Conclusions We describe the different elements of the POCUS rotations currently offered in Canadian Internal Medicine training programs. We share some lessons learned around the elements necessary for a sustainable rotation that meets high educational standards. We also identify areas for future growth, which include the expansion of learner policies, as well as the evolution of trainee assessment in the era of competency-based medical education. Our results will help educators that are endeavoring setting up POCUS rotations achieve success.

description: Every creek gulley and raw interrupted by roadway fills and embankments must be provided with an adequate drainage conduit under the pavement. If the natural drainage is impeded or the conduit is not functioning properly, impounded water over-runs the pavement, seeps through the fill, and eventually disintegrates the section or reduces its stability. The topography in Kentucky, through varied sectionally, requires on the average, one cross-drain for every thousand feet of roadway. Obviously, these drainage structures are of considerable economic importance in the highway program, not only from the standpoint of initial construction costs, but also from consideration of the service-efficiency or the permanence of the installation itself. Of these two factors, service-efficiency is undoubtedly the more important factor in determining an integrated service economy. Since permanence of a culvert or cross-drain depends largely on the specific properties of the material with which it is made, considerable advantage may be derived by selecting material for use in areas where their properties are compatible with the conditions of service, and excluding them where condition are known to be unfavorable.

description: Quantised sound waves -- phonons -- govern the elastic response of crystalline materials, and also play an integral part in determining their thermodynamic properties and electrical response (e.g., by binding electrons into superconducting Cooper pairs). The physics of lattice phonons and elasticity is absent in simulators of quantum solids constructed of neutral atoms in periodic light potentials: unlike real solids, traditional optical lattices are silent because they are infinitely stiff. Optical-lattice realisations of crystals therefore lack some of the central dynamical degrees of freedom that determine the low-temperature properties of real materials. Here, we create an optical lattice with phonon modes using a Bose-Einstein condensate (BEC) coupled to a confocal optical resonator. Playing the role of an active quantum gas microscope, the multimode cavity QED system both images the phonons and induces the crystallisation that supports phonons via short-range, photon-mediated atom-atom interactions. Dynamical susceptibility measurements reveal the phonon dispersion relation, showing that these collective excitations exhibit a sound speed dependent on the BEC-photon coupling strength. Our results pave the way for exploring the rich physics of elasticity in quantum solids, ranging from quantum melting transitions to exotic ``fractonic'' topological defects in the quantum regime.

Subjects: subject: Transportation Engineering

description: On November 18, 1948, the assembly of joints with prefabricated neoprene sealers was demonstrated by representative of the Lastite Joint Company, 105 W. Madison Street, Chicago 2, Illinois, on the construction project on U.S. 27, about 5 miles south of Alexandria. Installation was not possible at that time due to the fact that the contract was temporarily without cement.  Installation was made on November 30, 1948, under the supervision of a representative of the company. This installation was not completely satisfactory due to the inexperience of the paving crew with this type of joint. The joint at Station 622÷22 was knocked askew by the finishing machine and makes an angle of about 20° with the vertical at one end (See Fig. 1). Another of the joints has an offset at the center of the joint, the cause of which is not known (See Fig. 2). The third joint resulted in a placement where the depth of the rubber with respect to the pavement surface varies, probably due to finishing difficulties and setting of the joint.

description: Locations for the Test Sections within the Control Sections and as close as possible to the Loadometer Stations established by the Division of Planning have been selected and are described in this report. With but one or two exceptions, there is reasonable certainty that these sections of pavement can be kept in service without major changes for a period of five years. However, there are repairs that should be made on the pavements in two of the sections in order to prevent rapid deterioration that is likely to occur if these are not corrected at the beginning of the study.

description: This paper presents the predictive accuracy using two-variate meteorological factors, average temperature and average humidity, in neural network algorithms. We analyze result in five learning architectures such as the traditional artificial neural network, deep neural network, and extreme learning machine, long short-term memory, and long-short-term memory with peephole connections, after manipulating the computer-simulation. Our neural network modes are trained on the daily time-series dataset during seven years (from 2014 to 2020). From the trained results for 2500, 5000, and 7500 epochs, we obtain the predicted accuracies of the meteorological factors produced from outputs in ten metropolitan cities (Seoul, Daejeon, Daegu, Busan, Incheon, Gwangju, Pohang, Mokpo, Tongyeong, and Jeonju). The error statistics is found from the result of outputs, and we compare these values to each other after the manipulation of five neural networks. As using the long-short-term memory model in testing 1 (the average temperature predicted from the input layer with six input nodes), Tonyeong has the lowest root mean squared error (RMSE) value of 0.866 $(%)$ in summer from the computer-simulation in order to predict the temperature. To predict the humidity, the RMSE is shown the lowest value of 5.732 $(%)$, when using the long short-term memory model in summer in Mokpo in testing 2 (the average humidity predicted from the input layer with six input nodes). Particularly, the long short-term memory model is is found to be more accurate in forecasting daily levels than other neural network models in temperature and humidity forecastings. Our result may provide a computer-simuation basis for the necessity of exploring and develping a novel neural network evaluation method in the future.

Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1949
Subjects: subject: Transportation Engineering

description: Four different methods of evaluating subgrade support under flexible pavements were studied: (1) Field CBR; (2) North Dakota Cone; (3) Bearing Plates; and (4) Laboratory CBR.  Approximately 435 miles of flexible pavements in Kentucky were represented. The roads were selected so as to give a wide range in conditions of traffic, soil areas, and design. A total of 185 locations were investigated, and 338 cone tests, 291 field CBR's, and 117 series of plate tests were conducted. There were 178 subgrade samples for which the laboratory CBR test was conducted. Undisturbed samples for future triaxial tests were obtained at 21 locations.  Subgrade moisture variation was considered. Traffic was determined by loadometer surveys and use of traffic flow maps.  For the traffic imposed, adequacy of the designs -- as indicated by the presence or absence of base failures was evaluated from the standpoint of subgrade support measured by the four methods of test. Comparisons among the various methods of test in determining the subgrade support were made. The ultimate objective is a design criteria for flexible pavements in Kentucky.

An Examination of Equipment for Preventing Segregation in Storage of Coarse Aggregates
Creators: name: Collier, S. T.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1949
Subjects: subject: Transportation Engineering

description: This is a report of an investigation of a device developed for the purpose of reducing to a minimum the segregation of coarse aggregates during delivery from chutes or conveyors to bins and other storage or transportation facilities.  Producers and consumers are always confronted, more or less, with segregation of materials, but methods toward its elimination have been moderately successful at best. As a matter of fact, the most successful of those methods have been those that required placement and distribution of loads in bins, stockpiles, barges, and the like, rather than the use of mechanical devices for prevention of segregation within the loads themselves.  It is the purpose of this report to present results of experimental work with a mechanical device for that purpose. The experiment was necessarily confined to miniature apparatus representing equipment that could reasonably be devised for actual application to aggregate production plants.
Cooperative Investigation of Joint Spacing in Concrete Pavements

Subjects: subject: Transportation Engineering

description: During the summer of 1940 the Kentucky Department of Highways, with the Public Roads Administration participating, constructed 6.27 miles of investigational pavement as a cooperative research project on joint spacing. This project was one of six planned by the Public Roads Administration and the Portland Cement Association in cooperation with six highway departments. The five other states participating were California, Michigan, Hinnesota, Missouri, and Oregon. The project selected for this jointing study in Kentucky is in Daviess County, approximately six miles southeast of Owensboro, on Kentucky Route No. 71 (Layout map in Figure 1).  The experimental program was outlined for the purpose of evaluating the relative merits of varying intervals in expansion joint spacing and of dummy contraction joints with and without dowel bars for load transfer. A complete discussion of the scope and purpose has been given in a paper by Mr. E. F. Kelly of the Public Roads Administration.
A Study of the Effect of Blended Coarse Aggregate on Air-Entrained Concrete Progress Report 3
Creators: name: Collier, S. T.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1949
Subjects: subject: Transportation Engineering

description: The purpose of this investigetion was to study the durability characteristics of a river gravel, used as coarse aggregate for concrete, with respect to four major fractions separated in accordance to their general mineralogical classification. This aggregate was from the same stock of Ohio River gravel that was used in earlier phases of this Project reported in 1947.  Since this gravel consisted of several rock types varying in mineralogic constituents, it was conceivable that poor performance could possibly be attributed to some undesirable fraction or fractions, rather than to the aggregate as a whole. The separation of this aggregate was rather general yet satisfactory for the purposes of this study and was confined to four fractions in each of which there was a preponderance of one general rock type. These four fractions were designated, for convenience, as limestone, chert, quartzite, and granite.  Evaluation of durability characteristics was made by means of freezing and thawing tests on like samples of concrete made with the different gravel components. All other features of the concrete were kept as constant as possible.

description: This work considers low-rank canonical polyadic decomposition (CPD) under a class of non-Euclidean loss functions that frequently arise in statistical machine learning and signal processing. These loss functions are often used for certain types of tensor data, e.g., count and binary tensors, where the least squares loss is considered unnatural.Compared to the least squares loss, the non-Euclidean losses are generally more challenging to handle. Non-Euclidean CPD has attracted considerable interests and a number of prior works exist. However, pressing computational and theoretical challenges, such as scalability and convergence issues, still remain. This work offers a unified stochastic algorithmic framework for large-scale CPD decomposition under a variety of non-Euclidean loss functions. Our key contribution lies in a tensor fiber sampling strategy-based flexible stochastic mirror descent framework. Leveraging the sampling scheme and the multilinear algebraic structure of low-rank tensors, the proposed lightweight algorithm ensures global convergence to a stationary point under reasonable conditions. Numerical results show that our framework attains promising non-Euclidean CPD performance. The proposed framework also exhibits substantial computational savings compared to state-of-the-art methods.

description: Background: Despite a publicly funded system, health care in Canada has been shown to be deeply inequitable, particularly toward Indigenous people. Based on research identifying key dimensions of equity-oriented health care as being cultural safety, harm reduction and trauma- and violence-informed care, an intervention to promote equity at the organizational level was tested in primary health care, refined and adapted, and tested in Emergency Departments (EDs). Methods In partnership with clinical, community and Indigenous leaders in three diverse EDs in one Canadian province, we supported direct care staff to tailor and implement the intervention. Intervention activities varied in type and intensity at each site. Survey data were collected pre- and post-intervention from every consecutive patient over age 18 presenting to the EDs (n = 4771) with 3315 completing post-visit questions in 4 waves at two sites and 3 waves (due to pandemic constraints) at the third. Administrative data were collected for 12 months pre- and 12 months post-intervention. Results Throughout the study period, the participating EDs were dealing with a worsening epidemic of overdoses and deaths related to a toxic drug supply, and the COVID 19 pandemic curtailed both intervention activities and data collection. Despite these constraints, staff at two of the EDs mounted equity-oriented intervention strategies; the other site was experiencing continued, significant staff shortages and leadership changeover. Longitudinal analysis using multiple regression showed non-significant but encouraging trends in patient perceptions of quality of care and patient experiences of discrimination in the ED. Subgroup analysis showed that specific groups of patients experienced care in significantly different ways at each site. An interrupted time series of administrative data showed no significant change in staff sick time, but showed a significant decrease in the percentage of patients who left without care being completed at the site with the most robust intervention activities. Conclusions The trends in patient perceptions and the significant decrease in the percentage of patients who left without care being completed suggest potential for impact. Realization of this potential will depend on readiness, commitment and resources at the organizational and systems levels.

description: There has been a growing interest in developing data-driven, and in particular deep neural network (DNN) based methods for modern communication tasks. For a few popular tasks such as power control, beamforming, and MIMO detection, these methods achieve state-of-the-art performance while requiring less computational efforts, less resources for acquiring channel state information (CSI), etc. However, it is often challenging for these approaches to learn in a dynamic environment. This work develops a new approach that enables data-driven methods to continuously learn and optimize resource allocation strategies in a dynamic environment. Specifically, we consider an ``episodically dynamic" setting where the environment statistics change in ``episodes", and in each episode the environment is stationary. We propose to build the notion of continual learning (CL) into wireless system design, so that the learning model can incrementally adapt to the new episodes, {\it without forgetting} knowledge learned from the previous episodes. Our design is based on a novel bilevel optimization formulation which ensures certain ``fairness" across different data samples. We demonstrate the effectiveness of the CL approach by integrating it with two popular DNN based models for power control and beamforming, respectively, and testing using both synthetic and ray-tracing based data sets. These numerical results show that the proposed CL approach is not only able to adapt to the new scenarios quickly and seamlessly, but importantly, it also maintains high performance over the previously encountered scenarios as well.

description: We present transport measurements of bilayer graphene with 1.38° interlayer twist and apparent additional alignment to its hexagonal boron nitride cladding. As with other devices with twist angles substantially larger than the magic angle of 1.1°, we do not observe correlated insulating states or band reorganization. However, we do observe several highly unusual behaviors in magnetotransport. For a large range of densities around half filling of the moiré bands, magnetoresistance is large and quadratic. Over these same densities, the magnetoresistance minima corresponding to gaps between Landau levels split and bend as a function of density and field. We reproduce the same splitting and bending behavior in a simple tight-binding model of Hofstadter's butterfly on a square lattice with anisotropic hopping terms. These features appear to be a generic class of experimental manifestations of Hofstadter's butterfly and may provide insight into the emergent states of twisted bilayer graphene.

Report No. 2 on a Concrete Pavement without Transverse Joints
Creators: name: Drake, William B.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1949
Subjects: subject: Transportation Engineering

description: This is a report of observations and operations pertaining to a concrete pavement without the usual transverse joints constructed during the summer of 1949.  The project which is on U.S. 31-W is designated as Simpson County, FI-239, and runs from Station 9+11 at the Tennessee State Line to Station 311+40 at the city limits of Franklin (See Fig. 1 for layout). It consists of a 22-foot concrete pavement underlain by 1-1/2-inches of compacted crushed limestone (Size No. 10) for insulation and leveling. The slabs are of air-entrained concrete made with the agent interground in the cement. There is a longitudinal joint at the center which is of metal with 1/2-inch deformed tie bars, but there are no transverse joints except for butt type joints at the end of each run. The paving was completed about the first of July 1949.  After this pavement was built it was suggested by the Bureau of Public Roads and the Division of Construction that the Reseprch Laboratory make observeation on the general performance of this pavement. Following the first detailed observations and general inspection of the road it was decided that the pattern of crack development and particularly the character of some of the cracks warranted attention from the standpoint of crack sealing compound included in conjuction with normal routine maintenance on the road was suggested.

description: In applications such as participatory sensing and crowd sensing, self-interested agents exert costly effort towards achieving an objective for the system operator. We study such a setup where a principal incentivizes multiple agents of different types who can collude with each other to derive rent. The principal cannot observe the efforts exerted directly, but only the outcome of the task, which is a noisy function of the effort. The type of each agent influences the effort cost and task output. For a duopoly in which agents are coupled in their payments, we show that if the principal and the agents interact finitely many times, the agents can derive rent by colluding even if the principal knows the types of the agents. However, if the principal and the agents interact infinitely often, the principal can disincentivize agent collusion through a suitable data-driven contract.

description: This is a report of observations and operations pertaining to a concrete pavement without the usual transverse joints constructed during the summer of 1949.  The project which is on U. S, 31-W is designated as Simpson County, FI-239 (4), and runs from Station 9+11 at the Tennessee State Line to Station 311+40 at the city limits of Franklin (See Fig. 1 for layout). It consists of a 22-foot concrete pavement underlain by 1-1/2-inches of compacted crushed limestone (Size No. 10) for insulation and leveling. The slabs are of air-entrained concrete made with the agent interground in the cement, There is a longitudinal joint at the center which is of metal with 1/2-inch deformed tie bars, but there are no transverse joints except for butt type joints at the end of each run. The paving was completed about the first of July 1949.  After this pavement was built it was suggested by the Bureau of Public Roads and the Division of Construction that the Research Laboratory make observation on the general performance of this pavement. Following the first detailed observations and general inspection of the road it was decided that the pattern of crack development and particularly the character of some of the cracks warranted attention from the standpoint of crack sealing methods, Accordingly some experimental installations of crack sealing compound included in conjunction with normal routine maintenance on the road was suggested.

Year: 1949
Subjects: subject: Transportation Engineering

description: This report covers work completed up to the present time on the measurement of irregularities affecting the riding qualities of high type bituminous Pavements. The largest portion of this study was devoted to new construction involving Class I, Plant Mix Bituminous Concrete pavements although other roads were studied on the same basis for comparison purposes.  The purpose of the project was to evaluate the roughness characteristics of high type bituminous pavements by measuring the surface irregularities and interpreting them in terms of existing specifications. In evaluating these pavement irregularities two methods were used; one with which the surface was actually measured for deviation from the tolerance limits; and the other which necessitated the use of a road-roughness device that provided a measure of the riding qualities in terms of inches of roughness per mile.
The Origins, Evolution, Current State, and Future of Green Products and Consumer Research: A Bibliometric Analysis

description: Green products are crucial for a sustainable future. Without a strong understanding of consumer intent toward green products and research gaps, translating the availability of green products into actual consumer and market acceptance is hampered. This article reviews the available literature on green products and their relationship to consumers through bibliometric analysis. We used VosViewer to globalize the topic mapping and Scimat for longitudinal analysis. The results show that the available literature can be divided into four clusters, and five periods representing four distinct eras can be defined. Published studies were found in only 15 of the 36 calendar years constituting the first era. The second era started a wave of increasing green product research. In the third era, the number of journals with publications related to green products peaked. After the diversification of the third era, the fourth era saw the consolidation of the main vectors of publication. Despite a slow start in 1974, the research on eco-friendly products has expanded significantly over the past decade. Nonetheless, one persistent weakness of the literature is that most studies use customer intent, not the purchase itself, as the dependent variable. Consequently, there is still enormous potential for further research.

description: This scientific opinion paper discusses the key topics of the European Commission's Proposal for a Recast Urban Wastewater Treatment Directive. It shows how the proposed changes could affect wastewater treatment in Germany and highlights further refinement needs. In general, the proposal of the revised UWWTD is endorsed. The clear shift from basic wastewater collection and treatment to efficient wastewater management will have a positive influence on various environmental targets. It will also reduce the impact of wastewater treatment on the receiving water bodies as well as the impact of climate change on both, our cities, and the environment. Quelle: www.umweltbundesamt.de

description: With several dozen binary black hole events detected by LIGO/Virgo to date and many more expected in the next few years, gravitational-wave astronomy is shifting from individual-event analyses to population studies. Using the GWTC-2 catalog, we perform a hierarchical Bayesian analysis that for the first time combines several state-of-the-art astrophysical formation models with a population of primordial black holes (PBHs) and constrains the fraction of a putative subpopulation of PBHs in the data. We find that this fraction depends significantly on the set of assumed astrophysical models. While a primordial population is statistically favored against certain competitive astrophysical channels, such as globular clusters and nuclear stellar clusters, a dominant contribution from the stable-mass-transfer isolated formation channel drastically reduces the need for PBHs, except for explaining the rate of mass-gap events like GW190521. The tantalizing possibility that black holes formed after inflation are contributing to LIGO/Virgo observations could only be verified by further reducing uncertainties in astrophysical and primordial formation models, and it may ultimately be confirmed by third-generation interferometers.
