Year: 2005
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: New physics and detector concepts for a future pp and heavy ion program at the RHIC-II accelerator facility will be discussed. I will focus on hadronic observables which enable us to gain a better understanding on the hadronization from a sQGP and the chiral symmetry restoration in a sQGP. The ultimate question of how matter acquires mass can be addressed by this program in a complementary way to the Higgs search in high energy physics. The contributions of the RHIC program to the study of QCD will be discussed in detail.

description: Using data from fieldwork conducted in Nepal, the impact of a project designed to commercialize vegetables and fruits—the Vegetable and Fruit Cash Crop Program (VFC)—on male and female time allocation is examined. Using a rigorous time collection methodology, activity patterns in households that adopt and do not adopt the new technology are profiled. Very few studies examine changing activity patterns of both men and women in response to commercialization of agriculture. Though women’s time is valuable in agriculture, it is also valuable in the production of child nutrition. The recent evolution in thinking as to the causes of child malnutrition—the three pillars being food intake, health, and time to care—warrants further analyses of the time trade-offs that women and men face when adopting new agricultural technologies. The VFC program was successful at targeting both men and women farmers in the sense that household participation resulted in increased head male and head female time spent growing vegetables and fruits. The responses varied, however, by the number of preschool children in residence. In households with more than one preschooler, the time trade-offs associated with VFC participation were not sizeable for the care of children under 5 years. In households with just one preschooler, the trade-offs were more important. In these households, preschoolers received less care from the male and female heads, who spent more time in both the cash crop and in the food crop. In these same households, the nonwork (leisure) time of men increased as a result of VFC participation, but for women, leisure time was unaffected. Thus in the short run, there is perhaps scope for protecting childcare time by reducing time to leisure. In the medium run, benefits may well accrue to unborn preschoolers if VFC participation empowers women.

description: Schemes of gravitationally induced decoherence are being actively investigated as possible mechanisms for the quantum-to-classical transition. Here, we introduce a decoherence process due to quantum gravity effects. We assume a foamy quantum spacetime with a fluctuating minimal length coinciding on average with the Planck scale. Considering deformed canonical commutation relations with a fluctuating deformation parameter, we derive a Lindblad master equation that yields localization in energy space and decoherence times consistent with the currently available observational evidence. Compared to other schemes of gravitational decoherence, we find that the decoherence rate predicted by our model is extremal, being minimal in the deep quantum regime below the Planck scale and maximal in the mesoscopic regime beyond it. We discuss possible experimental tests of our model based on cavity optomechanics setups with ultracold massive molecular oscillators and we provide preliminary estimates on the values of the physical parameters needed for actual laboratory implementations.

description: This paper assesses how the Programa Nacional de Educacion, Salud, y Alimentacion (PROGRESA) program has affected the school enrollment of Mexican youth in the first 15 months of its operation. PROGRESA provides poor mothers in poor rural communities with education grants, if their children attend school regularly. Enrollment rates are compared between groups of poor children who reside in communities randomly selected to participate in the initial phase of the PROGRESA program and those who reside in other comparably poor (control) communities. Preprogram comparisons document how well the randomized design is implemented, and double-differenced estimators are reported over time within this panel of children. Probit models are then estimated for the probability that an individual child is enrolled, which statistically controls for additional characteristics of the child, their parents, local schools, and community, and for samples of different compositions, to evaluate the sensitivity of the estimated program effects to these variations. If the current relationship of the program outlays to enrollments, and that of schooling to increased adult earnings, both persist in the future, the internal rate of return to the PROGRESA educational grants as an investment is estimated to be about 8 percent, which accrues in addition to the programs efficacy as a poverty reduction program.

description: US expenditures on beef products have shown a slow but consistent increase during the last decade. Beef purchases are determined largely by product attributes and the importance that consumers attach to them. Preferences have changed and consumers have become more concern about beef quality, attributes, and safety in general. This study presumes that beef cuts exist at a national level and that consumers know about the different attributes among beef products. These circumstances have encouraged the beef industry to differentiate and add value to its production chain in order to satisfy the increasing demand for a large variety of cuts and product forms. The importance of developing new products has prompted research that identifies consumer trends. Hence, the objective of this paper is to study household purchase behavior and determine the impact of a series of variables expected to affect the frequency of purchasing among beef cut categories across time. Of major interest in this study is if consumers tend to buy just one type of beef during a buying occasion or more.

description: Many applications of machine learning on discrete domains, such as learning preference functions in recommender systems or auctions, can be reduced to estimating a set function that is sparse in the Fourier domain. In this work, we present a new family of algorithms for learning Fourier-sparse set functions. They require at most $nk - k \log_2 k + k$ queries (set function evaluations), under mild conditions on the Fourier coefficients, where $n$ is the size of the ground set and $k$ the number of non-zero Fourier coefficients. In contrast to other work that focused on the orthogonal Walsh-Hadamard transform, our novel algorithms operate with recently introduced non-orthogonal Fourier transforms that offer different notions of Fourier-sparsity. These naturally arise when modeling, e.g., sets of items forming substitutes and complements. We demonstrate effectiveness on several real-world applications.

description: We demonstrate the existence of equilibrium states in the limiting cases of the double-Kerr solution when one of the constituents is an extreme object. In the `extreme-subextreme' case the negative mass of one of the constituents is required for the balance, whereas in the `extreme-superextreme' equilibrium configurations both Kerr particles may have positive masses. We also show that the well-known relation |J|=M^2 between the mass and angular momentum in the extreme single Kerr solution ceases to be a characteristic property of the extreme Kerr particle in a binary system.

Diagnosis
Beloitoceras with compressed cross section; in longitudinal section, antisiphuncular conch margin nearly straight approaching mature peristome; angle of expansion of phragmocone typically more than 17°; mature conch with maximum height and width at peristome. (Adopted from Frye 1987.)
Material examined
ESTONIA • 1 spec.; Haapsalu holm; Adila Formation, Pirgu Regional Stage; TUG 939-56.
Type locality and horizon
Kallholn, Dalarna, Sweden; Boda Limestone, late Katian.
Description
The specimen is a fragment of a phragmocone with a conch height that increases from 20 mm to 29 mm and respective conch width increasing from 13 mm to 21 mm (angle of expansion = 18°). The conch cross section is oval compressed with narrower prosiphuncular side (CHI: 1.4–1.5). The conch surface is not preserved. The sutures form shallow lateral lobes and rounded saddles on the venter and dorsum. Mid-laterally, the sutures are 3.3 mm apart where the conch height is 24 mm (RCL = 0.14). The septal necks are cyrtochoanitic. The siphuncle is relatively narrow, and slightly expanded within the chambers (Fig. 29C)
Remarks
This specimen can be identified as B. siljanense because of the characteristic straightened dorsal conch margin as well as of the relatively large angle of expansion.

Cyclotron emission effect on CMB spectral distortions

description: We investigated the role of the cyclotron emission (CE) associated to cosmic magnetic fields (MF) on the evolution of cosmic microwave background (CMB) spectral distortions. We computed the photon and energy injection rates by including spontaneous and stimulated emission and absorption. These CE rates have been compared with those of bremsstrahlung (BR) and double Compton scattering (DC), for realistic CMB distorted spectra at various cosmic epochs. For reasonable MF strengths we found that the CE contribution to the evolution of the CMB spectrum is much smaller than the BR and DC contributions. The constraints on the energy exchanges at various redshifts can be then derived, under quite general assumptions, by considering only Compton scattering (CS), BR, and DC, other than the considered dissipation process. Upper limits to the CMB polarization degree induced by CE have been estimated.

description: We propose an operator product expansion for planar form factors of local operators in $\mathcal{N}=4$ SYM theory. This expansion is based on the dual conformal symmetry of these objects or, equivalently, the conformal symmetry of their dual description in terms of periodic Wilson loops. A form factor is decomposed into a sequence of known pentagon transitions and a new universal object that we call the "form factor transition". This transition is subject to a set of non-trivial bootstrap constraints, which we expect to be sufficient to fully determine it. We evaluate the form factor transition for MHV form factors of the chiral half of the stress tensor supermultiplet at leading order in perturbation theory and use it to produce OPE predictions at any loop order. We match the one-loop and two-loop predictions with data available in the literature.

description: We revisit the implications of Haag's theorem in the light of the renormalization group. There is still some lack of discussion in the literature about the possible impact of the theorem on the standard (as opposite of axiomatic) quantum field theory, and we try to shed light in this direction. Our discussion then deals with the interplay between Haag's theorem and renormalization. While we clarify how perturbative renormalization (for the sub-class of interactions that are renormalizable) marginalizes the its impact when the coupling is formally small, we argue that a non-perturbative and non-ambiguous renormalization cannot be built if there is any reference to the interaction picture with free fields. In other words, Haag's theorem should be regarded as a no-go theorem for the existence of a non-ambiguous analytic continuation from perturbative to non-perturbative QFT.

description: CIMMYT has invested a large and significant amount of public expenditures in wheat breeding research each year for several decades. Estimates of the impact of the wheat breeding program on wheat yield increases provides information to scientists, administrators, and policy makers regarding the efficacy and the rate of return to these investments, providing important information for future funding decisions. Using CIMMYT test plot data from the Yaqui Valley in Mexico from 1990-2002, regression results indicate that the release of modern CIMMYT varieties has contributed approximately 53.77 kg/ha to yield annually. The growing conditions of the experiment fields located in the Yaqui Valley approximate 40% of the developing world's wheat growing conditions. A rough estimate of the gains attributed to CIMMYT's wheat breeding program on a global scale is 304 million (2002) USD annually during the period 1990-2002. CIMMYT's total wheat breeding cost in 2002 was approximately 6 million dollars, making the benefit cost ratio approximately 50 to 1.

description: The distribution of lot sizes and associated improvements affect property values. Hence, zoning affects municipal property tax revenues. If optimal lot size is inconsistent with the targeted zoning density in a community, municipal revenue can be increased through zoning change. This paper theoretically derives the optimal lot size that maximizes tax revenues as a function of the elasticities of improvement value and lot size prices with respect to density, and the elasticities of land and improvement demand with respect to lot size. Empirical hedonic pricing model estimates for a Michigan Community suggest that the optimal lot size for recently sold property is lower than current zoning on existing properties. The possibility that municipal revenue can be enhanced through greater zoning density hints of a cost associated with exclusionary zoning. Local units of government should therefore more seriously consider the fiscal implications of their zoning decisions as they pursue growth control.

description: Location information offered by external positioning systems, e.g., satellite navigation, can be used as prior information in the process of beam alignment and channel parameter estimation for reconfigurable intelligent surface (RIS)-aided millimeter wave (mmWave) multiple-input multiple-output networks. Benefiting from the availability of such prior information, albeit imperfect, the beam alignment and channel parameter estimation processes can be significantly accelerated with less candidate beams explored at all the terminals. We propose a practical channel parameter estimation method via atomic norm minimization, which outperforms the standard beam alignment in terms of both the mean square error and the effective spectrum efficiency for the same training overhead.

description: Numerical simulations are reported on the Bonabeau model on a fully connected graph, where spatial degrees of freedom are absent. The control parameter is the memory factor f. The phase transition is observed at the dispersion of the agents power h_i. The critical value f_C shows a hysteretic behavior with respect to the initial distribution of h_i. f_C decreases with the system size; this decrease can be compensated by a greater number of fights between a global reduction of the distribution width of h_i. The latter step is equivalent to a partial forgetting.

description: This paper addresses the question how team production promotes efficiency of a firm when some inputs can be rewarded on the basis of outputs but some cannot because they are shared among outputs and non-separable. A multi-activity DEA model with variable returns to scale is proposed to provide information on the efficiency performance for organizations with inputs shared among several closely related activities. The model is applied to study the case of 279 farmers' associations in Taiwan. The result suggests that it is important to improve the efficiency of the non-profit oriented activities to improve their overall performances. Three out of four departments of TFAs can gain from economies of scale through expansion, while the remaining one gains through contraction. Thus, policies promoting structural adjustment and consolidations of TFAs would not be inconsistent with public interests.

description: Using the type-I SPDC process in BBO nonlinear crystal (NLC), we generate a polarization-entangled state near to the maximally-entangled Bell-state with high-visibility (high-brightness) $ 98.50 \pm 1.33 ~ \% $ ($ 87.71 \pm 4.45 ~ \% $) for HV (DA) basis. We calculate the CHSH version of the Bell inequality, as a nonlocal realism test, and find a strong violation from the classical physics or any hidden variable theory (HVT), $ S= 2.71 \pm 0.10 $. Via measuring the coincidence count (CC) rate in the SPDC process, we obtain the quantum efficiency of single-photon detectors (SPDs) around $ (25.5\pm 3.4) \% $, which is in good agreement to their manufacturer company. As expected, we verify the linear dependency of the CC rate vs. pump power of input CW-laser, which may yield to find the effective second-order susceptibility crystal. Using the theory of the measurement of qubits, includes a tomographic reconstruction of quantum states due to the linear set of 16 polarization-measurement, together with a maximum-likelihood-technique (MLT), which is based on the numerical optimization, we calculate the physical non-negative definite density matrices, which implies on the non-separability and entanglement of prepared state. By having the maximum likelihood density operator, we calculate precisely the entanglement measures such as Concurrence, entanglement of formation, tangle, logarithmic negativity, and different entanglement entropies such as linear entropy, Von-Neumann entropy, and Renyi 2-entropy. Finally, this high-brightness and low-rate entangled photons source can be used for short-range quantum measurements in the Lab.

description: Self-powered drug-delivery systems based on conductive polymers (CPs) that eliminate the need for external power sources are of significant interest for use in clinical applications. Osmium redox polymer-mediated glucose/O2 enzymatic biofuel cells (EBFCs) were prepared with an additional CP–drug layer on the cathode. On discharging the EBFCs in the presence of glucose and dioxygen, model drug compounds incorporated in the CP layer were rapidly released with negligible amounts released when the EBFCs were held at open circuit. Controlled and ex situ release of three model compounds, ibuprofen (IBU), fluorescein (FLU), and 4′,6-diamidino-2-phenylindole (DAPI), was achieved with this self-powered drug-release system. DAPI released in situ in cell culture media was incorporated into retinal pigment epithelium (RPE) cells. This work demonstrates a proof-of-concept responsive drug-release system that may be used in implantable devices.

description: For a system described by a multivariate probability density function obeying the fluctuation theorem, the average dissipation is lower-bounded by the degree of asymmetry of the marginal distributions (namely the relative entropy between the marginal and its mirror image). We formally prove that such lower bound is tighter than the recently reported bound expressed in terms of the precision of the marginal (i.e., the thermodynamic uncertainty relation) and is saturable. We illustrate the result with examples and we apply it to achieve the most accurate experimental estimation of dissipation associated to quantum annealing to date.

description: It was recently shown that the string theory duals of certain deformations of the N=4 gauge theory can be obtained by a combination of T-duality transformations and coordinate shifts. Here we work out the corresponding procedure of twisting the dual integrable spin chain and its Bethe ansatz. We derive the Bethe equations for the complete twisted N=4 gauge theory at one and higher loops. These have a natural generalization which we identify as twists involving the Cartan generators of the conformal algebra. The underlying model appears to be a form of noncommutative deformation of N=4 SYM.

description: Long memory, and more precisely fractionally integration, has been put forward as an explanation for the persistence of shocks in a number of economic time series data as well as to reconcile misleading findings of unit roots in data that should be stationary. Recent evidence suggests that long memory characterizes not commodity futures prices but rather price volatility (generally defined as $L_p$ norms of price logreturns). One implication of long memory in volatility is the mispricing of options written on commodity futures, the consequence of which is that fractional Brownian motion should replace geometric Brownian motion as the building block for option pricing solutions. This paper asks whether findings of long memory in volatility might be spurious and caused either by fragile and inaccurate estimation methods and standard errors, by correlated short memory dynamics, or by alternative data generating processes proven to generate the illusion of long memory. We find that for nine out of eleven agricultural commodities for which futures contracts are traded, long memory is spurious but is not caused by the effect of short memory. Alternative explanations are addressed and implications for option pricing are highlighted.

description: We have experimentally created a robust, ultrabright and phase-stable polarization-entangled state close to maximally entangled Bell-state with $ \% 98 $-fidelity using the type-II spontaneous parametric down-conversion (SPDC) process in periodically-poled KTiOPO$ _4 $ (PPKTP) collinear crystal inside a Sagnac interferometer (SI). Bell inequality measurement, Freedman's test, as the different versions of CHSH inequality, and also visibility test which all can be seen as the nonlocal realism tests, imply that our created entangled state shows a strong violation from the classical physics or any hidden-variable theory. We have obtained very reliable and very strong Bell violation as $ S=2.78 \pm 0.01 $ with high brightness $ \mathcal{V}_{\rm HV}= \% (99.969 \pm 0.003) $ and $\mathcal{V}_{\rm DA}= \% (96.751 \pm 0.002) $ and very strong violation due to Freedman test as $ δ_{\rm F} = 0.01715 \pm 0.00001 $. Furthermore, using the tomographic reconstruction of quantum states together a maximum-likelihood-technique (MLT) as the numerical optimization, we obtain the physical non-negative definite density operator which shows the nonseparability and entanglement of our prepared state. By having the maximum likelihood density operator, we calculate some important entanglement-measures and entanglement entropies. The Sagnac configuration provides bidirectional crystal pumping yields to high-rate entanglement source which is very applicable in quantum communication, sensing and metrology as well as quantum information protocols, and has potential to be used in quantum illumination-based LIDAR and free-space quantum key distribution (QKD).

description: We present the decomposition of the stellar velocity ellipsoid using stellar velocity dispersions within a 40 deg wedge about the major-axis (sigma_maj), the epicycle approximation, and the asymmetric drift equation. Thus, we employ no fitted forms for sigma_maj and escape interpolation errors resulting from comparisons of the major and minor axes. We apply the theoretical construction of the method to integral field data taken for NGC 3949 and NGC 3982. We derive the vertical-to-radial velocity dispersion ratio (sigma_z / sigma_R) and find (1) our decomposition method is accurate and reasonable, (2) NGC 3982 appears to be rather typical of an Sb type galaxy with sigma_z / sigma_R = 0.73 (+0.13/-0.11) despite its high surface brightness and small size, and (3) NGC 3949 has a hot disk with sigma_z / sigma_R = 1.18 (+0.36/-0.28).

description: While patients with angiogram-negative subarachnoid hemorrhages (ANSAH) have better prognoses than those with aneurysmal SAH, frailty’s impact on outcomes in ANSAH is unclear. We previously showed that the modified frailty index (mFI-11) is associated with poor outcomes following ANSAH. Here, we compared the mFI-5, mFI-11, Charlson Comorbidity Index (CCI), and temporalis thickness (TMT) to determine which index was the best predictor of ANSAH outcomes and mortality rates. In this retrospective cohort analysis between 2014 and 2018, patients with non-traumatic, angiogram negative SAH (ANSAH) were identified. The admission mFI-5, mFI-11, CCI, and TMT were calculated for each patient. Primary outcomes were mortality rate, discharge location, and prolonged length of stay (PLOS; LOS >85th percentile). Multivariate logistic regression and receiver operating characteristic (ROC) curves were used to evaluate frailty as predictors of primary endpoints. We included 75 patients with a mean age of 55.4 ± 1.5 years. There were 4 patient deaths (5.3%), 53 patients (70.7%) discharged home, and 11 patients (14.7%) with PLOS. On ROC analysis, the mFI-5 had the highest discriminatory value for mortality (AUC = 0.97) while the mFI-11 was most discriminatory for discharge home (AUC = 0.85) and PLOS (AUC = 0.78). On multivariate analysis, the only independent predictor of mortality was the mFI-11 (OR = 0.46; 95%CI: 1.45–14.23; p = 0.009) while the mFI-5 was the best predictor of discharge home (OR = 0.21; 95% CI: 0.08–0.61; p = 0.004). On multivariate analysis, the only independent predictor of PLOS was the Hunt and Hess score (OR = 2.63; 95%CI: 1.38–5.00; p = 0.003). The CCI and TMT were inferior to either mFI for predicting primary endpoints. Increasing frailty is associated with poorer outcomes and higher mortality following ANSAH. The mFI-5 and mFI-11 were found to be superior predictors of discharge home and mortality rate. While larger prospective study is needed, frailty, as measured by mFI-11 and -5, should be considered when evaluating ANSAH prognosis.

description: The assumption that the Standard Model is an Effective Field Theory (SM EFT) of a more fundamental theory at a higher, than electroweak, energy scale, implies a growth of cross-sections for electroweak Vector Boson Scattering (VBS) processes signalling the appearance of a resonance (or resonances) nearby that scale. In this article, we investigate in detail SM EFT effects from dimension-6 operators in VBS with like-sign-$W$ production in fully leptonic decay modes at the High Luminosity LHC (HL-LHC). We find that these effects are important for a handful of operators, most notably for the operator composed of three $SU(2)$ field strength tensors responsible for strong transversely polarized vector boson interactions. Current global fits on Wilson-coefficients allow for a signal immediately permissive at the HL-LHC if not accessible at the current LHC-dataset.

description: Based on an experimental study of two-body and three-body collisions in ultracold strontium samples, a novel optical-sympathetic cooling method in isotopic mixtures is demonstrated. Without evaporative cooling, a phase-space density of $6\times10^{-2}$ is obtained with a high spatial density that should allow to overcome the difficulties encountered so far to reach quantum degeneracy for Sr atoms.

description: Although the EU is still in a quasi moratorium stage concerning GM crops, doors for GM crops in the sugar industry seem to open. Herbicide tolerant sugar beet could mean a boost for the sugar beet sector. The ex ante impact assessment shows a created welfare of 15 billion during 1996-2014. The rule of thumb found in ex post impact studies of a sharing out between downstream and upstream sector of 2/3 versus 1/3 is seems to be applicable to this case as well. The sugar beet sector and consumers worldwide are the winners while cane growers lose due to technology eroded world prices. The reform of the EU Common market organization for sugar in 2006 seems to create an incentive for innovation to efficient European sugar producers. Crowding out of inefficient producers could take place as was one of the goals of the reform.
Ambipolar decay of magnetic field in magnetars and the observed magnetar activities

description: Magnetars are comparatively young neutron stars with ultra-strong surface magnetic field in the range $10^{14-16}$ G. The old neutron stars have surface magnetic field some what less $\sim 10^8$ G which clearly indicates the decay of field with time. One possible way of magnetic field decay is by ambipolar diffusion. We describe the general procedure to solve for the ambipolar velocity inside the star core without any approximation. With a realistic model of neutron star we determine the ambipolar velocity configuration inside the neutron star core and hence find the ambipolar decay rate and time scale which is consistent with the magnetar observations.

description: We present an alternative approach to unveil a different kind of entanglement in bipartite quantum states whose diagonal zero patterns in suitable matrix representations admit a nice description in terms of triangle-free graphs. Upon application of a local averaging operation, the separability of such states transforms into a simple matrix positivity condition, the violation of which implies the presence of entanglement. We completely characterize the class of triangle-free graphs which allows for nontrivial entanglement detection using the above test. Moreover, we develop a recipe to construct a plethora of unique classes of positive partial transpose (PPT) entangled triangle-free states in arbitrary dimensions. Finally, we link the task of entanglement detection in general states to the well-known graph-theoretic problem of finding triangle-free-induced subgraphs in a given graph.

description: The necessity to develop a priority system to guide the allocation of resources to the conservation of endangered species is widely recognized. The economic theory of biodiversity has established a framework to do so, and has identified priority criteria that should be considered when making conservation decisions. This paper uses a random effects ordered probit model of endangered species recovery to simulate the effects of reallocating conservation funds among species listed under the Endangered Species Act according to these criteria. Our results suggest that if the goal of conservation policy is to preserve a diverse set of species, reallocating conservation funds according to criteria identified by economic theory would yield an improvement over actual spending patterns without significant tradeoffs in terms of overall species recovery.

description: Σε όλο τον χριστιανικό κόσμο, κάθε χώρα, κάθε τόπος τιμά έναν άγιο που αφιέρωσε τη ζωή και την ψυχή του στη δόξα του Θεού, στους συνανθρώπους του, στο όνομα της αγάπης, της υψηλότερης από όλες τις εντολές που άφησε ο Ιησούς Χριστός στην ανθρωπότητα. Για τον λαό της Γερμανίας αυτός ο άγιος είναι ο Βονιφάτιος. Δίδαξε με αυτοθυσία και μέσα σε δυσκολίες και κακουχίες που προκλήθηκαν είτε από ανθρώπινους είτε από φυσικούς παράγοντες και μετέδωσε τα μηνύματα της αγάπης, της αλληλεγγύης και της προσφοράς ενώ ταυτόχρονα έβγαζε τη Γερμανία από το σκοτάδι του παγανισμού. Το έργο του Αγίου Βονιφάτιου ήταν σπουδαίο, καθώς άφησε μια σειρά από επιστολές, κηρύγματα και μερικά ποιήματα που επιτρέπουν στον σύγχρονο αναγνώστη να τον γνωρίσει και να τον μελετήσει. Μέσα από την κληρονομιά του, είναι εύκολο να γίνει αντιληπτή η βαθιά γνώση των Γραφών, η αναφορά του στη Ρωμαϊκή Έδρα, η μίμηση του αποστόλου των εθνών Παύλο, αλλά και η αναγνώριση του έργου του ήδη από τους συγχρόνους του, καθώς ο Βονιφάτιος τιμάται ως ένας άγιος από την Ορθόδοξη Εκκλησία και την Καθολική, αλλά και τη Λουθηρανική και την Αγγλικανική.
description: Throughout the Christian world, each country, each place honors a saint who dedicated his/her life and soul to the glory of God, to his/her fellow human beings, in the name of love, the highest of all commands that Jesus Christ left to humanity . For the people of Germany this saint is Boniface. He taught with self-sacrifice and in the midst of difficulties and hardships caused either by human or natural factors and he transmitted the messages of love, solidarity and giving while at the same time bringing Germany out of the darkness of paganism. Saint Boniface's work was great, as he left a series of letters, sermons and some poems that allow the modern reader to get to know him and study him. Through his legacy, it is easy to perceive the profound knowledge of the Scriptures, his reference to the Roman See, his imitation of the apostle of the nations Paul, but also the recognition of his work already by his contemporaries, as Boniface is honored as a saint by the Orthodox church and the Catholic, but also the Lutheran and the Anglican.
