description: Operation status of rural boarding school construction in Guizhou Province in China is introduced and its implementation status is comprehensively evaluated. Problems in the implementation of relevant policies of boarding project are put forward, including incomplete overall planning, impetuous implementation of polices in some regions and unfair allocation of accommodation subsidies. Difficulties in the development of rural boarding school are discussed, such as liability management of school, poor teaching force, lack of professional manager and special funds, prominent difficulties in board and lodging, problems of safety management and health care, heavy financial burden on the family, lack of mental health education, infrastructure failing to meet the development needs of school, and backward education consciousness of parents in poverty areas. Based on this, advantages and disadvantages of rural boarding project are analyzed from three aspects of government, school, and the student and parent. Then, relevant countermeasures are put forward to construct and develop rural boarding school according to the actual situation of Guizhou Province, such as strengthening policy support, improving education consciousness of parents, developing human resources in new school, and paying attention to the effects of local culture on school.

description: Registered nurses are faced with the task of providing quality nursing care in environments where the workload has increased and resources have diminished. In order to maintain their role in caring for patients and families, it is important that nurses describe the essential services they provide in our health care system because those services are not well understood and often go unrecognized. Narrative inquiry methods were used in this study to gain information and understanding about how nursing practice makes a difference to patients and families. A sample of 12 registered nurses working in critical care areas of a large urban hospital in British Columbia volunteered to participate. Data was obtained through interviews that were audiotaped and transcribed verbatim. Nurses were asked to share stories about how their nursing practice made a difference to patients and families. Four narratives and one sub-narrative made up the findings. The narratives were as follows: 1) Making a difference every day; 2) Going the extra mile; 3) Putting myself in their shoes; and 4) Staying composed in hopeless situations. The sub-narrative was It's not me, I'm part of a team. In the first narrative, nurses' stories were about providing competent routine nursing care ranging from life-saving events to the little things that nurses did that resulted in clear demonstrations of appreciation by patients and families. In the second narrative, nurses' stories reflected how nurses made a difference to patients and families by doing everything in their power to make the hospital experience as positive as possible. In these stories nurses emphasized how they challenged norms, went against hospital policies, and sometimes confronted colleagues and other health care members to ensure patients and families received the care they needed. In the third narrative, nurses' stories of making a difference involved imagining what it was like for their patients and families to be in the hospital. Nurses described how they used this strategy to anticipate what patients and families needed in planning their care. In the fourth narrative, nurses' stories described situations where they provided support to patients and families throughout the dying process by remaining realistic yet positive and always kind. Because nurses stayed composed they were able to focus on ensuring patient and family dignity throughout the grieving process. The sub-narrative revealed stories about how nurses were able to make a difference to patients and families by working as members of nursing teams and health care teams. Findings from this research suggest that autonomous decision-making, along with increased levels of clinical expertise, and knowledge and commitment to work as a member of a team contributed to nurses' abilities to make a difference. The findings suggest important implications to nursing practice, nursing education, and future nursing research.

description: Present research discusses experimental results of simultaneous action of heavy metals’ different concentrations and radiation on the intensity of post-radiation recovery in Lemna minor L. The effect caused by the heavy metals was modeling via adding cadmium and zinc ions into the plant’s medium during its cultivation. It was shown that at specific concentrations zinc ions have capability to increase intenstiy of plant’s post-radiation recovery under irradiation with relatively low doses. It should be noted that similar phenomenon was not detected while using cadmium ions. At all cadmium ion concentrations, used in the experiment, increase in the negative effects of gamma radiation was observed. Moreover, increasing the zinc ion concentrations resulted in nullifying of all the positive effects, as well as with the use of cadmium the negative effect caused by radiation exposure was increased.

description: Embedded atoms or molecules in a photoexcited He nanodroplet are well-known to be ionized through inter-atomic relaxation in a Penning process. In this work, we investigate the Penning ionization of acetylene oligomers occurring from the photoexcitation bands of He nanodroplets. In close analogy to conventional Penning electron spectroscopy by thermal atomic collisions, the n = 2 photoexcitation band plays the role of the metastable atomic $1s2s$ $^{3,1}S$ He$^\ast$. This facilitates electron spectroscopy of acetylene aggregates in the sub-kelvin He environment, providing the following insight into their structure: The molecules in the dopant cluster are loosely bound van der Waals complexes rather than forming covalent compounds. In addition, this work reveals a Penning process stemming from the n = 4 band where charge-transfer from autoionized He in the droplets is known to be the dominant relaxation channel. This allows for excited states of the remnant dopant oligomer Penning-ions to be studied. Hence, we demonstrate Penning ionization electron spectroscopy of doped droplets as an effective technique for investigating dopant oligomers which are easily formed by attachment to the host cluster.

description: Guiding ideology and objective of new agricultural science and technology service system in Beijing City are introduced based on the development status of agricultural science and technology service system in Beijing. Then, the six components of new agricultural science and technology service system in Beijing City are analyzed, which are government department system, public welfare extension agency system for agricultural technology, agrotechnical extension agent system at village level, scientific research institution system, peasants economic cooperative organization system, and agriculture-related enterprise system. And the three transmission routes of agricultural science and technology service are also put forward, such as public welfare service route of agricultural science and technology, operating service route of agricultural science and technology, and supporting route of agricultural science and technology. Among them, operating service route can be divided into government-guided industrialization transmission route and market-oriented technology transmission route. Finally, concrete ideas for establishing the new agricultural science and technology service system in Beijing City are discussed from four aspects, including mechanism construction, talent team construction, institution and organization construction, and support and guarantee.
Using Machine Learning to Find Ghostly Damped Ly$α$ Systems in SDSS DR14

description: We report the discovery of 59 new ghostly absorbers from the Sloan Digital Sky Survey (SDSS) Data Release 14 (DR14). These absorbers, with $z_{\rm abs}$$\sim$$z_{\rm QSO}$, reveal no Ly$α$ absorption, and they are mainly identified through the detection of strong metal absorption lines in the spectra. The number of previously known such systems is 30. The new systems are found with the aid of machine learning algorithms. The spectra of 41 (out of total of 89) absorbers also cover the Ly$β$ spectral region. By fitting the damping wings of the Ly$β$ absorption in the stacked spectrum of 21 (out of 41) absorbers with relatively stronger Ly$β$ absorption, we measured an HI column density of log$N$(HI)=21.50. This column density is 0.5dex higher than that of the previous work. We also found that the metal absorption lines in the stacked spectrum of the 21 ghostly absorbers with stronger Ly$β$ absorption have similar properties as those in the stacked spectrum of the remaining systems. These circumstantial evidence strongly suggest that the majority of our ghostly absorbers are indeed DLAs.

description: Necessity of establishing the early-warning mechanism of food security is introduced, which is mainly shown in five aspects. First is the particularity of China's national and food condition: China has large population and immense consumption base. Once food insecurity occurs in an all-round way, China could not buy all the food needed from the international market. The second aspect is the importance of food as a commodity: food is the most basic means of subsistence for human being, playing a role of social "stabilizer". It is also the basis of the national economy. The third aspect is the fluctuation of food supply: inter-annual variation of grain production is significant in China; and early-warning information of food security is needed in order to stabilize the fluctuation of food supply. The fourth one is the potential crisis in food marketization: both supply and demand of food are relatively small, which is unable to make great response to market price. Thus, risk of food security is exacerbated. The fifth aspect is the political nature of food as a commodity: food, an important strategic resource, has important impact on the political and military actions of a state. Measures to improve the early-warning mechanism of food security are discussed. Firstly, set up an independent early-warning mechanism, which is the premise to improve the early-warning mechanism of food security. Secondly, establish the operating principle of early-warning mechanism, mainly including systematic principle, qualitative and quantitative principle, principle of high efficiency, and principle of integrating legal, administrative and economic means. Thirdly, ascertain the operation mode of early-warning mechanism. Government leading mode should be selected based on the actual situation of China. Fourthly, increase the input in early warning and improve the quality of early-warning information of food security. Fifthly, confirm the legal responsibilities of related subjects, in order to ensure the normal operation of early-warning mechanism and to exert its due social function.

description: The economic viability of agriculture-based enterprises for farm women has been studied along with the constraints and prospects for these enterprises in the Punjab state by selecting the districts of Amritsar and Gurdaspur. Amongst the different enterprises adopted by the women, the four have been identified as most popular, viz. dairy, bee-keeping, papar/ badi and pickles making. The study has been conducted with a total sample of 100 women entrepreneurs for the year 2004-05. The study has revealed the age group of most of the women entrepreneurs as 36 to 65 years. The average annual household income of the women entrepreneurs has been found to vary between Rs 1.66 lakh for the dairy enterprise to Rs 2.16 lakh for the bee-keeping enterprise. The share of enterprise income in household income has been found 18.89% (the lowest) for the dairy enterprise and 72.84 per cent for the papar/badi enterprise. Amongst the different enterprises selected for study, papar/badi enterprise has been observed as the most successful/viable enterprise, followed by beekeeping, pickles making and the dairy enterprise. Marketing, lack of capital, problems of being the women and technical deficiency have been identified as the major problems faced by the women entrepreneurs. To make these enterprises viable, there is a need of subsidy on the purchase of inputs, reduction in formalities for getting credit from the institutional sources, and financing of input costs by the formal banking institutions. To increase the profit from bee-keeping and pickles enterprises, the entrepreneurs should try to sell their products directly to the consumers.

General localization of the radioisotope in the organs of the experimental plant was shown by radioautography method. Radioactivity characteristics of both soil and study plant organs has been determined by spectrometric analysis. It is concluded that the presented Chenopodium album L. can be used as a marker test system to study the penetration and distribution of radionuclides from the soil in the bodies of wild-growing weeds, which in turn creates a precondition for implementation of effective cleaning of contaminated areas by radionuclide and phytoremediation measures.

Publisher: name: Radiobiology and Radiation Safety
Year: 2021

description: Prediction, prevention and treatment of early and especially late adverse effects of radiation therapy is an urgent task in modern biology and medicine. The aim of the present study was to evaluate the informativeness and clinical efficacy of cyto and molecular-genetic characteristics of genome instability in terms of diagnosis and prognosis of radiogenic complications. 30 oncologic patients with larynx cancer (stage 2 end 3) undergoing the radiotherapy were investigated. The irradiation was carried out on a linear accelerator: 2Gy/fraction, total dose 70 Gy, Leucocytes, dicentric chromosomes, level of micronuclei in buccal (MnB) and erythrocytes and level of DNA-Cometbefore irradiation, after receiving half and total dose were investigated. Exploratory and confirmatory data analyses methods (K-mean Clustering, ANOVA, Xi2) were used. To identify the optimal predictors of the risk of complications, a Binary Logistic Regression analysis and Receiver operating characteristic (ROC) curve analysis was performed. After receiving a half-dose of irradiation a statistically significant changes of all characteristics is observed in patients (F≥9.21; p<0.001). Clustering patients by the amplitude of radio-induced deviations from the background level (level before irradiation) of characteristics revealed groups of low and high risk of complications.It was confirmed that there is a causal relationship between the stage of the disease and the risk of complications, although its statistical significance is close to the threshold value (χ2 = 8.22, p = 0.051), which indicates that the stage of the disease is not the only factor that determines the risk of complications.Analysis of the cyto and molecular-genetic profile of the complication risk revealed a statistically significant relationship between it and the frequency of dicentric chromosomes, level of micronuclei in erythrocytes and buccal cells (F ≥ 5; p ≤ 0.05). The levels of leukocytes and DNA comets depend on both the stage and the level of risk (F ≥ 5; p ≤ 0.05). To determine the optimal predictors of the risk of complications, a binary logistic regression analysis was performed. It was found that the strongest predictors are the background level of DNA comets (regression coefficient = 0.89 ± 0.41; p = 0.029) and the micronuclei level in buccal cells (regression coefficient = 21.92 ± 8.86; p = 0.013). Using the Receiver Operating Characteristic analysis, revealed the high clinical efficacy of the criterion (AUC = 0.93), and the optimal Cutoff_level (0,5), providing Sensitivity = 0.866 and Specifity = 0.875. Our results suggest that levelofthe of DNA comets together with level of MnBbefore treatment can be used to predict the risk of developing complication afterradiotherapy.

description: Self-complementary metasurfaces have gained significant attention due to their unique frequency-independent transmission and reflection properties and the possibility of the polarization transformation of plane waves. In this paper, we focus on the near-field spectrum to investigate both theoretically and experimentally the properties of surface waves supported by anisotropic self-complementary metasurfaces. We show that as a consequence of the electromagnetic Babinet's duality, such structure is hyperbolic for any frequency. We reveal the polarization degree of freedom inherent to plane waves by demonstrating the broadband TE-TM polarization degeneracy of the surface waves along two principal directions. We demonstrate the possibility of switching the canalization direction of 90 degrees by a very small frequency shift paving a way to the extreme tunability and surface wave routing. The results obtained open a plethora of opportunities for practical applications, including flat polarization devices, optical data processing systems and antennas.

description: The sustainability issue of the crop productivity is fast emerging. The post-Green Revolution phase is characterized by high input-use and decelerating total factor productivity growth (TFPG). The agricultural productivity attained during the 1980s has not been sustained during the 1990s and has posed a challenge for the researchers to shift the production function upward by improving the technology index. It calls for an examination of issues related to the trends in the agricultural productivity, particularly with reference to individual crops grown in the major states of India. Temporal and spatial variations of TFPG for major crops of India have also been examined.

description: The pattern of development and trends in productivity and profitability have been analysed to find whether Indian agriculture meets the requirements of sustainable development. The study is based on the secondary data culled from the publications of the Department of Agriculture and Department of Statistics, Govt. of India. A tremendous development and spectacular growth have been observed in agriculture during the past five decades, 1949-50 to 1999-2000. However, there has not been any spectacular modification in the technology since 1980s, leading to a continuous deceleration in the rates of growth of both production and productivity of most crops in recent years. Because of decline in yield, the economic condition of farmers has deteriorated. On the other side, nonagricultural sector has shown a growth of 6 per cent. This increasing disparity between per capita income of agricultural and non-agricultural sectors is likely to raise social disorder in the farming class.
Evidence for Intrinsic Redshifts in Normal Spiral Galaxies

Subjects: subject: Astrophysics (astro-ph)

description: The Tully-Fisher Relationship (TFR) is utilized to identify anomalous redshifts in normal spiral galaxies. Three redshift anomalies are identified in this analysis: (1) Several clusters of galaxies are examined in which late type spirals have significant excess redshifts relative to early type spirals in the same clusters, (2) Galaxies of morphology similar to ScI galaxies are found to have a systematic excess redshift relative to the redshifts expected if the Hubble Constant is 72 km s-1 Mpc-1, (3) individual galaxies, pairs, and groups are identified which strongly deviate from the predictions of a smooth Hubble flow. These redshift deviations are significantly larger than can be explained by peculiar motions and TFR errors. It is concluded that the redshift anomalies identified in this analysis are consistent with previous claims for large non-cosmological (intrinsic) redshifts.

description: This paper has examined the emerging issues, extent of transitions and their implications for the sustainable and balanced development of agriculture in the mountain areas of the country. The study undertaken in low and mid-hill regions of Himachal Pradesh is based upon the data collected during the period 2002-03 from 200 sample households selected from 10 villages, representing five major mountain farming systems (MFS), viz. maize-based, paddy-based, vegetable-based, fruit-based and livestock-based. It has been found that over a period of time lot of changes have taken place in the socio-economic milieu and agricultural practices in mountains. The cropping pattern, extent of diversification and commercialization have been found to vary considerably across different MFS. A high degree of externalities has developed particularly under vegetable- and fruit-based farming systems. The proportion of purchased inputs has increased while the share of farm-produced inputs (own seeds, FYM, family labour, bullock labour, feed and fodder, etc.) has decreased. Thus, the system interlinkages and in-built complementary relations among sub-systems are getting distorted with commercialization through vegetables and fruits. The shortage of fodder, decrease in the number of farm animals and thus FYM-scarcity, are the burgeoning signs of unsustainability, particularly on vegetable- and fruit-based systems. Therefore, the sustainable plans developed for different systems have revealed the possibility of increasing profitability by optimum combination of sub-components like cereals, pulses, vegetable crops, fruits, fodder resources and livestock and thus maintaining the crucial balance to harness in-built complementary relations of the sub-systems. The increasing externalities in the MFS clearly show the crucial role of markets and marketing in the agricultural development that needs greater policy support in future.

description: We present the main results derived from a chemical analysis carried out on a large sample of galactic O-rich AGB stars using high resolution optical spectroscopy (R~40,000-50,000) with the intention of studying their lithium abundances and/or possible s-process element enrichment. Our chemical analysis shows that some stars are lithium overabundant while others are not. The observed lithium overabundances are interpreted as a clear signature of the activation of the so-called ``Hot Bottom Burning'' (HBB) process in massive galactic O-rich AGB stars, as predicted by the models. However, these stars do not show the zirconium enhancement (taken as a representative for the s-process element enrichment) associated to the third dredge-up phase following thermal pulses. Our results suggest that the more massive O-rich AGB stars in our Galaxy behave differently from those in the Magellanic Clouds, which are both Li- and s-process-rich (S-type stars). Reasons for this unexpected result are discussed. We conclude that metallicity is probably the main responsible for the differences observed and suggest that it may play a more important role than generally assumed in the chemical evolution of AGB stars.

description: We investigate the basic constraint on amplifying the asymmetry in quantum states with correlated catalysts. Here a correlated catalyst is a finite-dimensional auxiliary, which exactly preserves its reduced state while allowed to become correlated to the quantum system. Interestingly, we prove that under translationally invariant operations, catalysts in pure states are useless in any state transformation, while with a correlated catalyst in a mixed state, one can enlarge the set of accessible states from an initially asymmetric state. Moreover, we show that the power of a catalyst increases with its dimension, and further, with a large enough catalyst, a qubit state with arbitrarily small amount of asymmetry can be converted to any mixed qubit state. In doing so, we build a bridge between two important results concerning the restrictions on coherence conversion, the no-broadcasting theorem and the catalytic coherence. Our results may also apply to the constraints on coherence evolution in quantum thermodynamics, and to the distribution of timing information between quantum clocks.

description: Thomas Cooper was a prolific inventor and brilliant engineer, at one time holding more patents than any other single person in England. He founded an engineering business in King's Lynn. In 1915 he invented and produced the first aerial bombs of their time. He recorded that the bombs were weighed 22lbs, 22 inches long overall, and the shell is 5 inches in diameter at the largest point.

The bombs did not have directional control so were just thrown out of the plane.

description: Voci dall'Inferno is a research project directed by Professor Marina Riccucci (University of Pisa) since 2016, with support from Professor Angelo Mario Del Grosso (CNR-ILC, Pisa) and contributions from numerous Digital Humanities students.The project has two integrated objectives: a) digitizing and encoding in XML-TEI format the first digital corpus of concentration camp survivors' non-literary testimonies, including written and oral sources; b) identifying, quantifying, and evaluating the presence of Dante's lexicon and allusions within these testimonies. The research is based on the observation that many survivors, regardless of their educational background, found in Dante's lexicon, particularly from the Divine Comedy's Inferno, a vocabulary to express the inexpressible experiences of the Lager. A web application, developed in the eXist-db environment using XQuery, enables publishing, querying, and analysis of the encoded data. By adhering to Text Encoding Initiative (TEI) guidelines, the project ensures a structured digital archive aligned with FAIR principles. Currently, the archive contains 18 individuals with 23 testimonies in XML-TEI format, including 13 oral and 10 written accounts. In total, 18 hours and 35 minutes of recordings and 390 pages of written testimonies have been transcribed and encoded. Initial investigation reveals that 11 of the 18 witnesses use quotations, allusions, or vocabulary from the Divine Comedy, totaling 68 references to Dante's work. Future development of the project will closely align with the CLARIN-IT collaboration and EHRI infrastructure, through the support of DiPText-KC and the Voices from Ravensbrück’ Project.

description: Numerical arguments are presented for the existence of regular and black hole solutions of the Einstein-Skyrme equations with a positive cosmological constant. These classical configurations approach asymptotically the de Sitter spacetime. The main properties of the solutions and the differences with respect to the asymptotically flat ones are discussed. It particular our results suggest that, for a positive cosmological constant, the mass evaluated as timelike infinity in infinite. Special emphasis is set to De Sitter black holes Skyrmions which display two horizons.

It’s not quite like home : a study of institutionalized seniors’ experiences
Creators: name: Grammer, Caroline E.
Publisher: name: University of British Columbia
Year: 2009

description: The focus of this research is to understand the experiences of institutionalized seniors existing within contemporary models of care and the impact of their institutional policies. This research examined how 8 institutionalized seniors, ranging in age from 65 years to 90 years, experienced daily living in a facility setting where a client-centred model of care is established. These personal experiences were then linked to a governing set of institutional policies. This study looks at the impact these policies have on these seniors' experiences. Qualitative data was gathered through in-depth interviews. These seniors recognized the irony of their marginalized experiences despite clientcentred models of care. This evolved as the major or overarching theme of this research. This theme was built on four paradoxical dimensions referred to as "incongruencies"; 1) home, but not home, 2) hurry up and wait, 3) very busy being bored, and 4) safe, but silenced. The informants worked in a variety of ways to cope with the incongruencies and contradictions in their environment including, lowering expectations, adopting dominant social language, values and beliefs, developing a survival support network, and manipulating the system to meet their needs. A discussion regarding the omission of key issues in policies, residual ageist policies contradicting current goals and philosophies of care facilities, and the failure to achieve genuine holistic client-centred care provide insight for social workers and health care professionals into the needs of frail institutionalized seniors.

description: This paper provides an illustration of evaluating productivity convergence using spatial econometric modelling framework for the aquaculture sector in India. Productivity has been measured using Total Factor Productivity (TFP). The b- and s-convergence concepts that are used to test the convergence hypothesis have been extended to examine the possible presence of spatial autocorrelation and spatial heterogeneity. The results have confirmed the productivity convergence hypothesis, the presence of spillover effects on TFP growth and the presence of spatial regimes in the TFP convergence process which have policy implications. The paper concludes by providing recommendations for further research.
A hadronic synchrotron mirror model for the "orphan" TeV flare in 1ES 1959+650

description: Very-high-energy gamma-ray flares of TeV blazars are generally accompanied by simultaneous flaring activity in X-rays. The recent observations by the Whipple collaboration of an ``orphan'' TeV flare of 1ES 1959+650 (without simultaneous X-ray flare) is very hard to reconcile with the standard leptonic SSC model which is routinely very successfully employed to explain the SED and spectral variability of TeV blazars. In this paper, an alternative scenario is suggested in which the ``orphan'' TeV flare may originate from relativistic protons, interacting with an external photon field supplied by electron-synchrotron radiation reflected off a dilute reflector. While the external photons will be virtually ``invisible'' to the co-moving ultrarelativistic electrons in the jet due to Klein-Nishina effects, their Doppler boosted energy is high enough to excite the $Δ$ resonance from relativistic protons with Lorentz factors of ~ 10^3 - 10^4. This model is capable of explaining the ``orphan'' TeV flare of 1ES 1959+650 with plausible parameters, thus constraining the number and characteristic energy of relativistic protons in the jet of this blazar.

description: We solved the three-nucleon Faddeev equation including relativistic features such as relativistic kinematics, boost effects and Wigner spin rotations. As dynamical input a relativistic nucleon-nucleon interaction exactly on-shell equivalent to the AV18 potential has been used. The effects of Wigner rotations for elastic scattering observables were found to be small. The boost effects are significant at higher energies.They diminish the transition matrix elements at higher energies and lead in spite of the increased relativistic phase-space factor as compared to the nonrelativistic one to rather small effects in the cross section, which are mostly restricted to the backward angles.

description: Living tissues undergo wetting transitions: On a surface, they can either form a droplet-like cell aggregate or spread as a monolayer of migrating cells. Tissue wetting depends not only on the chemical but also on the mechanical properties of the substrate. Here, we study the role of substrate stiffness in tissue spreading, which we describe by means of an active polar fluid model. Taking into account that cells exert larger active traction forces on stiffer substrates, we predict a tissue wetting transition at a critical substrate stiffness that decreases with tissue size. On substrates with a stiffness gradient, we find that the tissue spreads faster on the stiffer side. Further, we show that the tissue can wet the substrate on the stiffer side while dewetting from the softer side. We also show that, by means of viscous forces transmitted across the tissue, the stiffer-side interface can transiently drag the softer-side interface towards increasing stiffness, against its spreading tendency. These two effects result in directed tissue migration up the stiffness gradient. This phenomenon -- tissue durotaxis -- can thus emerge both from dewetting at the soft side and from hydrodynamic interactions between the tissue interfaces. Overall, our work unveils mechanisms whereby substrate stiffness impacts the collective migration and the active wetting properties of living tissues, which are relevant in development, regeneration, and cancer.
Lower Limit on Dark Matter Production at the Large Hadron Collider

description: We evaluate the prospects for finding evidence of dark matter production at the Large Hadron Collider. We consider WIMPs and superWIMPs, weakly- and superweakly-interacting massive particles, and characterize their properties through model-independent parameterizations. The observed relic density then implies lower bounds on dark matter production rates as functions of a few parameters. For WIMPs, the resulting signal is indistinguishable from background. For superWIMPs, however, this analysis implies significant production of metastable charged particles. For natural parameters, these rates may far exceed Drell-Yan cross sections and yield spectacular signals.
