description: We propose a potential scheme to generate entangled photons by manipulating trapped ions embedded in two-mode microcavities, respectively, assisted by a magnetic field gradient. By means of the spin-spin coupling due to the magnetic field gradient and the Coulomb repulsion between the ions, we show how to efficiently generate entangled photons by detecting the internal states of the trapped ions. We emphasize that our scheme is advantageous to create complete sets of entangled multi-photon states. The requirement and the experimental feasibility of our proposal are discussed in detail.

Polytopes, graphs and fitness landscapes
Creators: name: Crona, Kristina
Publisher: name: American University
Year: 2023

description: Darwinian evolution can be illustrated as an uphill walk in a landscape, where the surface consists of genotypes, the height coordinates represent fitness, and each step corresponds to a point mutation. Epistasis, roughly defined as the dependence between the fitness effects of mutations, is a key concept in the theory of adaptation. Important recent approaches depend on graphs and polytopes. Fitness graphs are useful for describing coarse properties of a landscape, such as mutational trajectories and the number of peaks. The graphs have been used for relating global and local properties of fitness landscapes. The geometric theory of gene interaction, or the shape theory, is the most fine-scaled approach to epistasis. Shapes, defined as triangulations of polytopes for any number of loci, replace the well established concepts of positive and negative epistasis for two mutations. From the shape one can identify the fittest populations, i.e., populations where allele shuffling (recombination) will not increase the mean fit- ness. Shapes and graphs provide complementary information. The approaches make no structural assumptions about the underlying fitness landscapes, which make them well suited for empirical work.

description: The Centers for Disease Control and Prevention (CDC) states that "foodborne disease remains one of the most common and important causes of illness and deaths"-this despite progress in improving the quality of food and food handling in the United States, such as canning, refrigerating, freezing, and pasteurizing foods. According to researchers at the CDC and the U.S. Food and Drug Administration (FDA), from 6.5 million to 33 million illnesses and up to 9,000 deaths may occur each year from foodborne microbes (namely, bacteria, parasites, viruses, and fungi). For just the few foodborne bacterial and parasitic diseases for which we have made cost estimates, medical charges and lost productivity cost society $5-6 billion annually (see box and table 1). In contrast to foodborne pathogens- which generally cause illness within hours or months-any toxicological effects from pesticide residues in food, in general, may take decades to manifest their chronic health effects. Such health risks are less easily tied to a particular cause. Most experts agree that pesticide residues in food pose minimal health risks. Nonetheless, questions continue to be raised about whether such risks are adequately understood and measured. For example, a recent National Academy of Sciences study questioned whether the current assessment of dietary risks from pesticide residues adequately accounts for their effects in children. This uncertainty has contributed to continued consumer concerns about pesticide risks (also see "Food Safety: Meal Planners Express Their Concerns," elsewhere in this issue).
Recombination and peak jumping

Publisher: name: American University
Year: 2023

description: We find an advantage of recombination for a category of complex fitness landscapes. Recent studies of empirical fitness landscapes reveal complex gene interactions and multiple peaks, and recombination can be a powerful mechanism for escaping suboptimal peaks. However classical work on recombination largely ignores the effect of complex gene interactions. The advantage we find has no correspondence for 2-locus systems or for smooth landscapes. The effect is sometimes extreme, in the sense that shutting off recombination could result in that the organism fails to adapt. A standard question about recombination is if the mechanism tends to accelerate or decelerate adaptation. However, we argue that extreme effects may be more important than how the majority falls.

description: Dust particles observed in extrasolar planetary discs originate from undetectable km-sized bodies but this valuable information remains uninteresting if the theoretical link between grains and planetesimals is not properly known. We outline in this paper a numerical approach we developed in order to address this issue for the case of dust producing collisional cascades. The model is based on a particle-in-a-box method. We follow the size distribution of particles over eight orders of magnitude in radius taking into account fragmentation and cratering according to different prescriptions. A very particular attention is paid to the smallest particles, close to the radiation pressure induced cut-off size $R_{pr}$, which are placed on highly eccentric orbits by the stellar radiation pressure....(abstract continued in the uploaded paper)

description: Person re-identification aims to identify a person from an image collection, given one image of that person as the query. There is, however, a plethora of real-life scenarios where we may not have a priori library of query images and therefore must rely on information from other modalities. In this paper, an attribute-based approach is proposed where the person of interest (POI) is described by a set of visual attributes, which are used to perform the search. We compare multiple algorithms and analyze how the quality of attributes impacts the performance. While prior work mostly relies on high precision attributes annotated by experts, we conduct a human-subject study and reveal that certain visual attributes could not be consistently described by human observers, making them less reliable in real applications. A key conclusion is that the performance achieved by non-expert attributes, instead of expert-annotated ones, is a more faithful indicator of the status quo of attribute-based approaches for person re-identification.

description: Discriminative stimulus functions of drugs of abuse play an important role in the acquisition, maintenance and reinstatement of drug-taking behavior. The present study tested whether two different schedules of stressor presentation, i.e., repeated and variable, for 10 days, can modify the discriminative stimulus effects of cocaine in male rats trained to discriminate cocaine (10 mg/kg, i.p.) from saline. Dopamine (DAT), serotonin (SERT) and norepinephrine (NET) transporter levels in mesocorticolimbic areas were also measured using western blotting after stress exposure to determine if the relative ratio of these proteins may explain differences in behavior. Rats exposed to both repeated and variable stress displayed shifts in the cocaine doseeresponse curve but with different patterns of responding. In handled controls, ED50 values for cocaine-like responding were stable after 10 days of handling compared to baseline. Repeated stress produced a transient left-ward shift in cocaine-like responding, indicating increased sensitivity to the cocaine cue. ED50 values after variable stress did not differ from baseline, although maximal cocaine-like responding was lower at the two highest doses of cocaine tested at which variably stressed rats exhibited more saline-like responding. Alterations in DAT and NET were found in the Repeated Stress group and DAT and SERT in the Variable Stress group in select brain regions which may be responsible for differences in behavior.

description: The United States is often said to have the safest food supply in the world, yet some consumers and policymakers counter that it is still not safe enough. The U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA) of the U.S. Department of Health and Human Services are continually examining ways to reduce the risk of foodborne illnesses. But regulatory actions come at a cost to the Government, industry, and consumers. These costs can in turn raise prices for consumers. On the other hand, greater safety may not cost significantly more if it can be achieved through stricter control of existing practices. With budgets stretching ever tighter, tradeoffs are involved. Those concerned with food safety are asking: How much risk does each individual actually face from foodborne illnesses? And, how much should society pay to reduce that risk? Although it is difficult to determine the total amount spent on food safety by the Federal Government, local and State authorities, the food processing and distribut-ing industry, and consumers, the total is high. Many Federal agencies are involved in ensuring the safety of the U.S. food supply. Expenditures on food safety by FDA alone totaled $206.3 million in fiscal 1992, up from $93.8 million in fiscal 1980. USDA's Food Safety and Inspection Service (FSIS) spent about $473.5 million in fiscal 1992, down from $530.7 million in fiscal 1980. Furthermore, Government expenditures are a small part of the total, because most of the cost of regulation is paid by private partiesprocessors, retailers, and foodservice operators-complying with health regulations.

description: X-ray emission from the cluster of galaxies A3667 was measured by the PCA and HEXTE experiments aboard the RXTE satellite during the period December 2001 - July 2002. Analysis of the ~141 ks RXTE observation and lower energy ASCA/GIS data, yields only marginalevidence for a secondary power-law emission component in the spectrum. The 90% confidence upper limit on nonthermal emission in the 15-35 keV band is determined to be 2.6x10^{-12} erg/(cm^{2}s). When combined with the measured radio flux and spectral index of the dominant region of extended radio emission, this upper limit implies a lower limit of ~0.4 microgauss on the mean, volume-averaged intracluster magnetic field in A3667.

description: Metal-poor components of dwarf galaxies around the Milky Way could be remnants of the building blocks of the Galactic halo structure. Low-mass stars that are currently observed as metal-poor stars are expected to have formed in chemically homogeneous clusters in the early phases of galaxy formation. They should have already disintegrated and should exhibit large scatter in abundance ratios of some sets of elements (e.g., Sr/Ba) in the Milky Way field stars. However, chemical abundance ratios are expected to cluster in very metal-poor stars in dwarf galaxies because the number of clusters formed in individual galaxies in the very early phase is expected to be quite limited. We examine the possible clustering of abundance ratios of Sr and Ba in the Sextans dwarf galaxy to test for the clustering star formation scenario. We investigate a total of 11 elements (C, Mg, Ca, Sc, Ti, Cr, Mn, Ni, Zn, Sr, Ba) in five stars in the Sextans dwarf galaxy. Previous studies suggest that these have similar abundance ratios. In this study, we focus on the abundance ratio of Sr to Ba. The observations are based on high-resolution spectroscopy (R = 40 000) using the Subaru Telescope High Dispersion Spectrograph. The distribution of $α$/Fe abundance ratios of the Sextans dwarf galaxy stars is slightly lower than the average of the values of stars in the Galactic halo. The Sr/Ba abundance ratios for the five metal-poor stars are in good agreement, and this clumping is distinctive compared to the [Sr/Ba] spread seen in the metal-poor halo stars. We find that the probability of such clumping is very small if the Sextans stars have distributions of Sr and Ba abundances similar to halo stars.

Importantly, recent work shows that adolescents are also protected from the aversive effects of many abusable drugs as measured by conditioned taste avoidance (CTA). However, such effects of methylphenidate (MPH, widely prescribed to adolescents with ADHD) have not been characterized. Objectives The effect of age on MPH-induced CTA was assessed.

description: It is common to hear that the U.S. food supply is among the safest in the world. Yet, it is equally common to hear concerns expressed about it-particularly over microbial contamination, such as the much-publicized cases of E. coli-tainted hamburgers in the West, and pesticide residues, such as the scare over Alar pesticide on apples. In a recent national survey by the University of Kentucky, primary household food shoppers revealed their opinions on food safety (fig. 1). Their top three concerns were fats and cholesterol (33.7 percent of respondents), bacterial food poisoning such as salmonellosis and botulism (30.0 percent), and pesticide residues on food (18.4 percent). While previous consumer surveys have ranked pesticides as the top food-safety concern, the rankings in this survey reflect current scientific evidence which indicates that pesticides pose a lower risk to consumers than does microbial contamination.

description: Combining symmetry based considerations with inputs from available experimental results, we make the case that a novel spin-triplet superconductivity triggered by antiferromagnetic fluctuations may be realized in the newly discovered layered cobaltide Na$_x$CoO$_{2}\cdot y$H$_2$O. In the proposed picture, unaccessable via resonating-valence-bond physics extrapolated from half-filling, the pairing process is similar to that advanced for Sr$_{2}$RuO$_4$, but enjoys a further advantage coming from the hexagonal structure of the Fermi-surface which gives a stronger pairing tendency.

description: The Anderson model of a twofold spin degenerate impurity level in the limit of infinite Coulomb repulsion, $U \to \infty$, coupled to one and two degenerate conduction bands or channels, is considered in pseudo-particle representation. We extend the Conserving T-Matrix Approximation (CTMA), a general diagrammatic approximation scheme based on a fully renormalized computation of two-particle vertex functions in the spin and in the charge channel, to the calculation of thermodynamic and spectral properties. In the single-channel case, the CTMA yields in the Kondo regime a temperature independent Pauli spin susceptibility for temperatures below the Kondo temperature $T_K$ and down to the lowest temperatures considered, reproducing the exact spin screening in the Fermi liquid state. The impurity spectral density appears to remain non-singular down to the lowest temperatures, in agreement with Fermi liquid behavior. However, the unitarity sum rule, which is crucial for an impurity solver like the CTMA to be applicable within Dynamical Mean Field Theories for strongly correlated lattice models, is overestimated at the lowest temperatures. We argue that this shortcoming may be due to numerical imprecision and discuss an appropriate scheme for its correction. In the two-channel case, the spectral density calculated within CTMA exhibit qualitatively the correct non-Fermi liquid behavior at low temperatures, i.e. a powerlaw singularity.

description: Why is only a small proportion of all produce organically grown? One important factor may be that farmers would grow it only if enough consumers are willing to pay a higher price to compensate for the higher production costs. However, as organic farming methods become more advanced and experienced organic farmers become more adept at increasing yields, the additional costs would likely come down. But since surveys show that consumers state they are willing to pay significantly more for organic produce when it has the same cosmetic quality as conventionally grown produce, there could be other explanations for the small showing of organics in the food market. (See "Consumers Want Reduced Exposure to Pesticides on Food," in this issue for more on consumers' willingness to pay to reduce risks from pesticide residues.) Some suspect that an important constraint on the growth of or-ganics is a reluctance on the part of food companies to carry it. A recent survey of tomato handlers in the Mid-Atlantic region supports this belief.

description: Angiogenesis is a vital process for normal tissue development and wound healing, but is also associated with a variety of pathological conditions. Using this protocol, angiogenesis may be measured in vitro in a fast, quantifiable manner. Primary or immortalized endothelial cells are mixed with conditioned media and plated on basement membrane matrix. The endothelial cells form capillary like structures in response to angiogenic signals found in conditioned media. The tube formation occurs quickly with endothelial cells beginning to align themselves within 1 hr and lumen- containing tubules beginning to appear within 2 hr. Tubes can be visualized using a phase contrast inverted microscope, or the cells can be treated with calcein AM prior to the assay and tubes visualized through fluorescence or confocal microscopy. The number of branch sites/nodes, loops/meshes, or number or length of tubes formed can be easily quantified as a measure of in vitro angiogenesis. In summary, this assay can be used to identify genes and pathways that are involved in the promotion or inhibition of angiogenesis in a rapid, reproducible, and quantitative manner.

A Minimal Spontaneously Broken Hidden Sector and its Impact on Higgs Boson Physics at the Large Hadron Collider
Creators: name: Schabinger, Robert
name: Wells, James D.
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Little experimental data bears on the question of whether there is a spontaneously broken hidden sector that has no Standard Model quantum numbers. Here we discuss the prospects of finding evidence for such a hidden sector through renormalizable interactions of the Standard Model Higgs boson with a Higgs boson of the hidden sector. We find that the lightest Higgs boson in this scenario has smaller rates in standard detection channels, and it can have a sizeable invisible final state branching fraction. Details of the hidden sector determine whether the overall width of the lightest state is smaller or larger than the Standard Model width. We compute observable rates, total widths and invisible decay branching fractions within the general framework. We also introduce the ``A-Higgs Model'', which corresponds to the limit of a hidden sector Higgs boson weakly mixing with the Standard Model Higgs boson. This model has only one free parameter in addition to the mass of the light Higgs state and it illustrates most of the generic phenomenology issues, thereby enabling it to be a good benchmark theory for collider searches. We end by presenting an analogous supersymmetry model with similar phenomenology, which involves hidden sector Higgs bosons interacting with MSSM Higgs bosons through D-terms.

description: Amid unparalleled coverage of the introduction of a new technology for milk production, the U.S. Food and Drug Administration (FDA) approved in late 1993 a synthetically produced hormone for cowscalled recombinant bovine somatotropin, or rbST-for commercial sale in the United States. Consumer-watch groups questioned the safety of milk and dairy products for human consumption from dairy cows receiving rbST, and some dairy suppliers and grocery stores indicated that they would not sell the products. Many want products made with milk from cows receiving rbST to carry labels. FDA, the Federal agency primarily responsible for determining the safety of new animal drugs and for labels on milk and dairy products, says these fears are unfounded. After considerable testing (the first study reporting results of rbST-supplementation of dairy cows was in 1982), they found rbST use to be safe to dairy cows and they found dairy products made with milkfrom treated cows to be safe for human consumption. The FDA Commissioner, David A. Kessler, has stated, "This has been one of the most extensively studied animal drug products to be reviewed by the agency. The public can be confident that milk and meat from bST-treated cows is safe to consume."

Nonextensive Pesin identity. Exact renormalization group analytical results for the dynamics at the edge of chaos of the logistic map

Publisher: name: arXiv
Year: 2003
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We show that the dynamical and entropic properties at the chaos threshold of the logistic map are naturally linked through the nonextensive expressions for the sensitivity to initial conditions and for the entropy. We corroborate analytically, with the use of the Feigenbaum renormalization group(RG) transformation, the equality between the generalized Lyapunov coefficient $λ_{q}$ and the rate of entropy production $K_{q}$ given by the nonextensive statistical mechanics. Our results advocate the validity of the $q$-generalized Pesin identity at critical points of one-dimensional nonlinear dissipative maps.

description: Earlier this year, the U.S. Food and Drug Administration (FDA) announced a groundbreaking initiative to further ensure the safety of the Nation's seafood. Known as Hazard Analysis Critical Control Points (HACCP), the plan requires seafood processors to adopt a program that identifies potential food-safety hazards and adopt controls specifically targeted to those hazards to prevent them from occurring or at least to minimize the likelihood of their occurrence. HACCP focuses on prevention of product contamination rather than on detection of contaminated products. Verification that HACCP is in place and is working would be an added feature of FDA's current system of periodic mandatory inspections of processing plants to produce a more effective system of ensuring the safety of seafood. FDA expects to finalize the rule in early 1995. The proposed rule, published for public comment on January 28, 1994, proposed an effective date of 1 year from the issuance of the final rule.

description: We have developed a thermodynamic model of the catalytic growth of multiwall carbon nanotubes from hydrocarbon precursors at elevated temperature. Using this model we have computed the heat distribution, and carbon concentration in the catalyst. Calculations delivered a analytical formula for the growth time and growth rate. We find that the growth is mainly driven by a concentration gradient within the catalyst, rather than a temperature gradient.
