description: U.S. housing advocates have called for a fundamental rethinking of the nation’s federal housing policies. In this study, I examined the geographic and household-level consequences of a plan that redistributes federal income tax expenditures from homeowners to very-low-income households. I propose, defend, and illustrate the effects of the SHELTER plan, a redistributive policy that a) is revenue neutral, b) is tenure neutral, c) is progressive, d) prioritizes local redistribution, and e) targets excess revenues to affordable housing production subsidies in communities where an increase in cash-based housing assistance is most likely to inflate housing rents. I demonstrate that the savings from the elimination of four homeownership tax expenditures would provide more than enough revenue to fund a universal housing allowance for all very-low-income households. Ignoring housing market adjustments, the plan would reduce housing cost burdens for the nation’s very-low-income renters by 36% and reduce very-low-income homeowners’ cost burdens by 28%. The SHELTER plan would provide a new foundation for local affordable housing and community development practice. Very-low-income households would receive a guaranteed housing allowance with no strings attached and local planners would have new roles in the design and implementation of localized solutions to the affordable housing crisis.
Identified charged hadron production in Pb-Pb collisions at the LHC with the ALICE Experiment

description: Identified particle spectra represent a crucial tool to understand the behavior of the matter created in high-energy heavy-ion collisions. The transverse momentum p_T distributions of identified hadrons contain informations about the transverse expansion of the system and constrain the freezeout properties of the matter created. The ALICE experiment has good particle identification performance over a broad p_T range. In this contribution the results for identified pions, kaons and protons in heavy-ion collisions at 2.76 TeV center-of-mass energy are presented. These results are compared with other identified particle measurements obtained by previous experiments, and discussed in terms of the thermal and hydrodynamic pictures. The status of extensions of this analysis, with the study of identified particles as a function of event-by-event flow in Pb-Pb collisions, is also discussed.

description: Literature reviews can play a pivotal role in designing urban policies. Here we introduce two tools used by public health specialists to assess the quality of studies and quantify the evidence derived from them: the Risk of Bias Assessment (RoB) and Evaluation of Certainty of Evidence (ECE). The RoB scores articles on several domains (e.g., selection bias, study design, etc.) to provide an appraisal of how rigorous the study is, whereas the ECE tool provides a framework to clearly state how much certainty there is in the outcomes under study. Both tools can be used to enhance literature review articles in urban planning to better inform practitioners on how to best develop policies using a rigorous approach.
Swept centerband decoupling as a technique in nuclear magnetic double resonance spectroscopy
Creators: name: Pietsch, Anton Emil
Publisher: name: California Institute of Technology
Year: 1976
Subjects: Chemistry

description: A technique of doubly modulated radiofrequency irradiation to achieve nuclear magnetic spin-spin decoupling was developed. The effectiveness of this technique, called Swept Centerband Modulation, was investigated by comparison study with other well known techniques. It was found that swept centerband modulation produced an averaging of single coherent frequency decoupling over an adjustable bandwidth. The conclusion drawn from the study was that this technique is not effective for wide band decoupling but very effective for medium to narrow band selective decoupling experiments.

description: We calculate the two-loop pressure of a plasma of quarks and gluons at finite temperature and chemical potential using the hard thermal loop perturbation theory (HTLpt) reorganization of finite temperature/density quantum chromodynamics. The computation utilizes a high temperature expansion through fourth order in the ratio of the chemical potential to temperature. This allows us to reliably access the region of high temperature and small chemical potential. We compare our final result for the two-loop HTLpt pressure at finite temperature and chemical potential with perturbative quantum chromodynamics (QCD) calculations and available lattice QCD results.

description: Despite recent interest in the experiences of planners working in the private sector, much research does not distinguish between different organizational contexts. A key change in the consultancy market is the rise of global, publicly traded firms that provide planning services. This research draws on interviews with planners working in publicly traded firms to understand the opportunities and constraints from this model of practice. Though some planners noted opportunities in publicly traded firms, participants identified more constraints or limitations related to this model of practice. Scaling up of firm size offered benefits, such as opportunities for collaboration, but these were limited by organizational structures that promoted competition and cost-cutting strategies. Financial pressures and market demands can affect professional practice, such as through increased time spent on financial reporting and capacity issues from frequent turnover in staff. As a small, low-value component of traded firms, planners experienced issues with reduced resources, difficulties with staffing, and a lack of understanding the role of planning. A limitation of the research is that relying on self-reported data may not fully reflect ethical or professional breaches. Increased collaboration across disciplines and geographies may improve project outcomes, though planners’ concerns about lack of capacity and oversight point to concerns for the clients of consultants, as well as professional associations. There is a need for commissioning agencies, particularly in the public sector, to pay close attention to issues of procurement and develop strategies to evaluate project work. In firms where planning is a small business line and subordinate to more profitable services, there may be emerging ethical and practice issues that have not received sufficient attention in professional codes.

description: Here we describe a critical link between drought risk management and planning at the local level, the traditional lack of overlap between these fields, and current and future opportunities for addressing drought within local drought planning. We used a national survey of American Planning Association members (n = 537) to examine local planners’ perceptions of drought planning strategies and barriers, as well as their jurisdictions’ current and future drought-addressing plans. Explanatory factors included planner experience, communication with water managers and hazard planners, and factors characterizing the drought threat and capacity of their jurisdictions. We found planners most amenable to collaboration with water conservation and hazard mitigation planning processes, somewhat amenable toward integrating drought into local land use plans and day-to-day policies, and less interested in undertaking standalone drought plans. Current and future drought planning endeavors were largely driven by the threat of drought and less so by the resources found within planners’ jurisdictions. State plans and mandates played a role by requiring plans and/or providing capacity for the process. Future planning efforts may be limited by the barriers planners perceive. Funding, in terms of local tax resources, does not appear to restrict where drought planning has taken place to date. Planners’ perceptions of leadership, political will, data, and coordination across jurisdictions as barriers are lessened through experience, communication with water managers and/or hazard planners, and state mitigation plans. Preparing for future drought impacts may require communities to adopt mitigation actions through local planning processes. Local planners may prefer to address drought through water and hazard plans, but land use plans and standalone plans may also be important tools for effective mitigation where drought poses a threat. Some of the barriers that planners face may be reduced through experience and communication with water and hazard planners, as well as their states’ engagement in statewide drought mitigation plans.

description: Although there is strong evidence that living in high-opportunity neighborhoods can improve the long-run educational and economic outcomes of children, translating this into practical advice for planners is difficult. There is little consensus about how to operationalize neighborhood opportunity, and planning discussions rarely consider how much that opportunity costs, even though planners around the country must grapple with the typically higher cost of providing housing in opportunity areas. We offer concrete guidance to planners about how to best overcome these barriers. We argue for a streamlined measure called the school–violence–poverty (SVP) index based on three contemporary metrics that research shows enhance economic mobility for children: school quality, violent crime, and poverty. Combining the SVP index with data on rental prices in New York City (NY) and Greater Boston (MA), we identified a collection of high-opportunity bargain neighborhoods with lower rents than expected given their opportunity metrics and housing characteristics. We found that high-opportunity bargain areas tended to be more affordable because they lacked amenities such as restaurants and proximity to the city center that are associated with higher rents but are unlikely to be very related to children’s economic mobility. Here we provide a streamlined, easy-to-use index for planners to identify high-opportunity bargain areas in their communities. It has direct implications for planners attempting to stretch limited budgets by helping planners decide where to get the most opportunity for their taxpayer dollars when building affordable housing and how to empower low-income families to weigh tradeoffs about where to live and achieve better neighborhood matches. The simplicity of the index can empower families to access areas that are more affordable and offer robust public services for their children.
The rotational motion of an ideal fluid and application to the three-dimensional flow through axial turbomachinery
Creators: name: Marble, Frank Earl

Subjects: Aeronautics
Aeronautical Engineering

description: The present paper discusses the principles and applications of an iteration method for solving certain problems involving rotational motion of an ideal fluid, such as occur in the presence of heat transfer, combustion, mechanical work processes, and non-uniform shock waves. The iteration process linearizes the essentially non-linear equations for rotational fluid motion by assuming a process for the vorticity transport, namely: the nth approximation is linearized by assuming the vorticity to be transported by the n-1th velocity field.  In some important cases, the first order solutions seem to offer considerable accuracy.

Two applications of the procedure are discussed in some detail, namely: 1) The process of straightening a non-uniform flow in a two-dimensional parallel-wall channel by means of a screen and 2) The three-dimensional flow in a multistage axial turbomachine having an infinite number of blades in each blade row.  The second of these, the three-dimensional flow through a turbomachine, is given detailed analysis bearing some analogy to the Prandtl theory of finite wings.  The results for the first order solution of velocity and enthalpy distributions are given explicitly and are shown to be defined by four relatively simple integrals.  The cases of rotating and stationary single blade rows are evaluated completely.  The general iteration process for obtaining higher approximations, utilizing the method of Green's functions, is given in some detail.

The calculations of the flow field generated by a blade row of given geometry is illustrated by the problem of a "vortex" turbomachine operating off the design condition.  The problem is found to be essentially non-linear in some respects, especially as to the approach to periodic solutions for a succession of similar stages.

description: Indoor residential environments will be an increasing source of dangerous heat exposure as summer temperatures rise. Although air conditioning is a recognized preventative measure, many vulnerable residents either lack air conditioning or cannot always afford the electricity. Understanding the relative influence of different building characteristics and percentages of tree canopy coverage on indoor air temperatures during extreme heat events can help prioritize intervention strategies. We measured indoor and outdoor temperatures at 140 homes in Detroit (MI), Atlanta (GA), and Phoenix (AZ) and surveyed residents to determine the presence of a working central air-conditioning system and their ability to afford utilities. For each home, we collected information on construction year, interior size, single versus multifamily structure, façade type, and percentage of tree canopy. After air conditioning, the importance of building characteristics versus tree canopy measures varied by city. In Detroit, masonry façades worsened the influence of outdoor temperatures, whereas increased tree canopy coverage moderated the influence. In Atlanta, building characteristics were not significant, but tree canopy moderated indoor temperatures in late afternoon. In Phoenix, some building characteristics moderated the influence of outdoor temperatures in late afternoon. In Detroit, only 35% of respondents had and used central air conditioning as needed compared with 57% in Atlanta and 95% in Phoenix. The influence of tree canopy and building characteristics on indoor temperatures varied by city depending on its background climate. We recommend adding questions about air conditioning and utility poverty to the U.S. Census. For rental properties, municipalities should establish and enforce maximum indoor temperature thresholds. States should include cooling in their Low Income Home Energy Assistance (LIHEAP) programs. Public cooling centers need to anticipate electricity outages. Urban planners must ensure efforts to increase mechanical cooling are powered by renewable energy sources.

description: The coronavirus (COVID-19) pandemic has had an unprecedented impact on small businesses in the United States. However, small business resilience scholarship has seldom investigated the experiences of minority-owned businesses. In this study I used an evolutionary resilience perspective to examine the experiences of Latina-owned businesses (LaOBs) in inland Southern California in coping with the pandemic. I conducted in-depth interviews and focus group discussions, both before and following the start of COVID-19, with a broad array of stakeholders from multiple sectors of the community. By triangulating their different perspectives, I found that the short-term crisis attributed to COVID-19 stems from long-term underinvestment in entrepreneurship and business development in underserved communities. Socioeconomic vulnerability at both the individual and community levels affects LaOBs’ resilience, a resilience conditioned by pre-pandemic networking and the institutional structures existing in underserved communities. This study is limited because it focused on only one study area, and it did not have access to large-scale quantitative data for comparative studies across ethnic groups and places. Building preparedness and resilience among racial and ethnic minority-owned businesses requires continuous investment in technology, education, and social network building in underserved communities, as well as the fostering of an inclusive entrepreneurship ecosystem. Planners should acknowledge and embrace a growing, critical mass of LaOBs as an opportunity to support economic and community development. Economic development policies, workforce development, and social policies targeting poverty alleviation and immigrant integration should be considered together. Engaging with the needs and aspirations of LaOBs and their communities will help generate more meaningful policies for underserved communities like these. The findings call for a forward-looking attitude toward developing a more transformational agenda that opens opportunities for underrepresented voices and challenges the problematic power structures existing in today’s society.

description: A new Quantum Monte-Carlo (QMC) approach is proposed to investigate low-lying states of nuclei within the shell model. The formalism relies on a variational symmetry-restored wave-function to guide the underlying Brownian motion. Sign/phase problems that usually plague QMC fermionic simulations are controlled by constraining stochastic paths through a fixed-node like approximation. Exploratory results in the sd and pf valence spaces with realistic effective interactions are presented. They prove the ability of the scheme to yield nearly exact yrast spectroscopies for both even- and odd-mass nuclei.

description: The spin-1/2 ferromagnetic-antiferromagnetic alternating Heisenberg chain with ferromagnetic next-nearest-neighbour (NNN) interaction is investigated. The ground state is the Haldane phase for weak NNN interaction, and is the ferromagnetic phase for weak antiferromagnetic interaction. We find a series of topologically distinct spin-gap phases with various magnitudes of edge spins for strong NNN interaction. The phase boundaries between these phases are determined on the basis of the DMRG calculation with additional spins that compensate the edge spins. It is found that each of the exact solutions with short-range antiferromagnetic correlation on the ferromagnetic-nonmagnetic phase boundary is representative of each spin gap phase.

description: According to a popular scenario supported by numerical models, the mass assembly and growth of massive galaxies, in particular the Early-Type Galaxies (ETGs), is, below a redshift of 1, mainly due to the accretion of multiple gas--poor satellites. In order to get observational evidence of the role played by minor dry mergers, we are obtaining extremely deep optical images of a complete volume limited sample of nearby ETGs. These observations, done with the CFHT as part of the \AD, NGVS and MATLAS projects, reach a stunning 28.5)29 mag.arcsec-2 surface brightness limit in the g' band. They allow us to detect the relics of past collisions such as faint stellar tidal tails as well as the very extended stellar halos which keep the memory of the last episodes of galactic accretion. Images and preliminary results from this on-going survey are presented, in particular a possible correlation between the fine structure index (which parametrizes the amount of tidal perturbation) of the ETGs, their stellar mass, effective radius and gas content.

description: The west end of the San Gabriel Mountains is a relatively small block of pre-Cretaceous metamorphic complex faulted from the main mass of the San Gabriel Mountains by the San Gabriel fault. Their core of metamorphic rocks is flanked on three sides by Tertiary sediments represented by Eocene, Pliocene, and Pleistocene formations.  The Eocene and Pliocene are characteristic off-shore and littoral marine deposits.  The Pleistocene is principally of terrestrial origin.

The area is one of structural complexity.  This can be accounted for, in part, by assuming that this end of the mountain block acted as a centre of rotation for north-south compressional forces that were active to the west.

The San Gabriel Range is believed to be a fault block, raised to its present elevation principally by movements along faults which parallel the north and south margins.  The faulting is not restricted to the extreme margins, but often is located within the range itself.

The west slope of the range is characterized by depositional relations between the sediments and the underlying mountain mass. If any faulting has occurred, it is thought to be farther west than the contact between the sediments and the basement complex and to be concealed beneath the younger sediments.

This is a direct consequence of the quantum nature of electricity in a normal conductor.

description: The termination shock of a pulsar wind is located roughly where the ram pressure matches that of the surrounding medium. Downstream of the shock, MHD models of the diffuse nebular emission suggest the plasma is weakly magnetized. However, the transition from a Poynting-dominated MHD wind to a particle-dominated flow is not well understood. We discuss a solution of this "sigma problem" in which a striped wind converts into a strong, superluminal electromagnetic wave. This mode slows down as it propagates radially, and its ram pressure tends to a constant value at large radius, a property we use to match the solution to the surrounding nebula. The wave thus forms a pre-cursor to the termination shock, which occurs at the point where the wave dissipates. Possible damping and dissipation mechanisms are discussed qualitatively.

description: We study the correspondence between four-dimensional supersymmetric gauge theories and two-dimensional conformal field theories in the case of N=2* gauge theory. We emphasize the genus expansion on the gauge theory side, as obtained via geometric engineering from the topological string. This point of view uncovers modular properties of the one-point conformal block on a torus with complexified intermediate momenta: in the large intermediate weight limit, it is a power series whose coefficients are quasi-modular forms. The all-genus viewpoint that the conformal field theory approach lends to the topological string yields insight into the analytic structure of the topological string partition function in the field theory limit.

description: Lateral superlattices have attracted major interest as this may allow one to modify spectra of two dimensional electron systems and, ultimately, create materials with tailored electronic properties. Previously, it proved difficult to realize superlattices with sufficiently short periodicity and weak disorder, and most of the observed features could be explained in terms of commensurate cyclotron orbits. Evidence for the formation of superlattice minibands (so called Hofstadter's butterfly) has been limited to the observation of new low-field oscillations and an internal structure within Landau levels. Here we report transport properties of graphene placed on a boron nitride substrate and accurately aligned along its crystallographic directions. The substrate's moire potential leads to profound changes in graphene's electronic spectrum. Second-generation Dirac points appear as pronounced peaks in resistivity accompanied by reversal of the Hall effect. The latter indicates that the sign of the effective mass changes within graphene's conduction and valence bands. Quantizing magnetic fields lead to Zak-type cloning of the third generation of Dirac points that are observed as numerous neutrality points in fields where a unit fraction of the flux quantum pierces the superlattice unit cell. Graphene superlattices open a venue to study the rich physics expected for incommensurable quantum systems and illustrate the possibility to controllably modify electronic spectra of 2D atomic crystals by using their crystallographic alignment within van der Waals heterostuctures.

In face of this growth, security threats also rise, compromising the Confidentiality, Integrity and Availability of the services provided. Our work is a Systematic Mapping where we hope to present metrics about publications available in literature that deal with some of the seven security threats in Cloud Computing, based in the guide entitled "Top Threats to Cloud Computing" from the Cloud Security Alliance (CSA). In our research we identified the more explored threats, distributed the results between fifteen Security Domains and identified the types of solutions proposed for the threats. In face of those results, we highlight the publications that are concerned to fulfill some standard of compliance.

description: We collect together results for bond percolation on various lattices from two to fourteen dimensions which, in the limit of large dimension $d$ or number of neighbors $z$, smoothly approach a randomly diluted Erdős-Rényi graph. We include new results on bond diluted hyper-sphere packs in up to nine dimensions, which show the mean coordination, excess kurtosis and skewness evolving smoothly with dimension towards the Erdős-Rényi limit.

description: M101 is an ideal target in which to test predictions of massive star birth and evolution. The large abundance gradient across M101 (a factor of 20) suggests that many more WR stars must be found in the inner parts of this galaxy than in the outer regions. Many HII regions and massive star-forming complexes have been identified in M101; they should be rich in WR stars, and surrounded by RSG stars. Finally, the Wolf-Rayet stars in M101 may be abundant enough for one to explode as a Type Ib or Ic supernova and/or GRB within a generation. The clear identification of the progenitor of a Type Ib or Ic supernova as a WR star would be a major confirmation of current stellar evolution theory. Motivated by these considerations, we have used the Hubble Space Telescope to carry out a deep, HeII optical narrowband imaging survey of the massive star populations in the ScI spiral galaxy M101. Combined with archival broadband images, we were able to image almost the entire galaxy with the unprecedented depth and resolution that only HST affords. We describe the extent of the survey and our images, as well as our data reduction procedures. A detailed study of a field east of the center of M101, containing the giant star-forming region NGC 5462, demonstrates how we find candidates, their properties and spatial distribution, and how we rule out most contaminants. The spatial distributions of the WR and RSG stars near a giant star-forming complex are strikingly different. WR stars dominate the complex core, while RSG dominate the complex halo. Future papers in this series will describe and catalog more than a thousand WR and RSG candidates that are detectable in our images, as well as spectra of many of those candidates.

description: We revisit the dynamical system based approach of spherically symmetric vacuum braneworlds, pointing out and studying the existence of a transcritical bifurcation as the dark pressure parameter changes its sign, we analyze some consequences of not discard the brane cosmological constant. For instance, it is noteworthy that the existence of an isothermal state equation between the dark fluid parameters cannot be obtained via the requirement of a quasi-homologous symmetry of the vacuum.

description: In this paper we study the interaction between the general form of viscous varying modified cosmic Chaplygin gas and the Tachyon fluid in the framework of Einstein gravity. We want to reconstruct the Tachyon potential and total equation of state parameter graphically by using numerical methods. In the presence of deceleration parameter, the interaction between components becomes sign changeable to explain different evolutionary eras in the universe. We review the potential and total equation of state parameter in Emergent, Intermediate and Logamediate scenarios of scale factor numerically. Analysis of total equation of state parameter show that, $ω_{tot}-1$ imply the phantom-like and quintessence-like behaviors respectively. we have checked the effects of cosmic and viscosity elements on the interaction process. Stability is checked in all the models by the squared velocity of sound.

description: This paper describes the results of a field and laboratory
study of the geology and ore deposits (dominantly the chromite properties) of the northeast quarter of the Seiad quadrangle, California.

The Seiad quadrangle is located in the central Klamath
Mountains in a region of rugged ridges and deep canyons. The oldest rocks are schists overlain by arenites, argillites, marble and meta-volcanic rocks. They are intruded and metamorphosed by quartz-diorite, chromium-bearing peridotite, and granodiorite probably
representing at least two phases of intrusion. Recent alluvium and remnants of old terrace gravels are found along the Klamath and Scott Rivers.

No definite ages have been assigned to the rocks because
of the lack of fossil evidence. The older rocks are probably pre-Mesozoic, while some of the terrace gravels may be of Pleistocene age.

The laboratory study of tie chromite ores indicates that
they are late magmatic (pneumotectic) ores whose structure is controlled by flowage, fracture-filling and replacement of the peridotite intrusions.

The chromite deposits described in this report are in
the Klamath Mountains of northern California. The oldest rocks in the area are mica, chlorite, and hornblende schists of pre Cambrian (?) age, which are overlain by a complex series of metamorphosed volcanic and sedimentary rocks of Paleozoic (?) age. Into all these rocks quartz diorite, peridotite, and granodiorite were successively intruded. Auriferous terrace gravels, possibly of Pleistocene age, Recent gravels, and alluvium partly fill some of the larger canyons.

The chromite deposits, which occur in peridotite, range in
size from a few tons to more than 100,000 tons. The ore of
minable grade has an average chromite content of 35 percent. Reserves in the district, as estimated from known outcrops, are believed to be approximately 125,000 tons. At current prices of $20 to $25 a ton it is unlikely that any of the deposits can be profitably worked. Though the major part of the tonnage is of low grade (20 percent of chromite), the material could be concentrated to a 45- or 50-percent product. Hand sorting would yield small tonnages of shipping ore.

description: In order to find alternative low-cost adsorbents for volatile organic liquids, the effectiveness of nickel oxide nanoparticles-modified diatomite (NONMD) in removing benzene was assessed. The impact of different operation parameters such as pH, contact time, initial benzene concentration, and adsorption dosage on the adsorption process was evaluated and optimum experimental conditions were identified. Surface area and morphology of the nanoparticles were characterized by scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) isotherms, X-ray diffraction (XRD), Fourier transform infrared (FTIR), and energy dispersive X-ray (EDX) analysis. The isotherm and kinetics effect of the adsorbent were evaluated.
