description: Lepton flavor violating Higgs boson decays are studied within the context of seesaw models with Majorana massive neutrinos. Two models are considered: The SM-seesaw, with the Standard Model Particle content plus three right handed neutrinos, and the MSSM-seesaw, with the Minimal Supersymmetric Standard Model particle content plus three right handed neutrinos and their supersymmetric partners. The widths for these decays are derived from a full one-loop diagrammatic computation in both models, and they are analyzed numerically in terms of the seesaw parameters, namely, the Dirac and Majorana mass matrices. Several possible scenarios for these mass matrices that are compatible with neutrino data are considered. In the SM-seesaw case, very small branching ratios are found for all studied scenarios. These ratios are explained as a consequence of the decoupling behaviour of the heavy right handed neutrinos. In contrast, in the MSSM-seesaw case, sizeable branching ratios are found for some of the leptonic flavor violating decays of the MSSM neutral Higgs bosons and for some choices of the seesaw matrices and MSSM parameters. The relevance of the two competing sources of lepton flavor changing interactions in the MSSM-seesaw case is also discussed. The non-decoupling behaviour of the supersymmetric particles contributing in the loop-diagrams is finally shown.

description: Large structural shifts in the global economy are causing a dramatic rise in the price of food. Since 1994, food prices in Trinidad and Tobago have risen above 350%, faster than the price of other items. From March 2006 to 2007, the food component of the retail price index increased by 19% whilst the overall price index increased by 8%. Sizable and fluctuating price differences have been recorded between wholesale and retail prices. Non-linear hedonic models are estimated using auction price and quality data for specific commodities and markets to examine whether buyers have systematic preferences for specific attributes (weight, sales lot size, market location and timing of sale) and whether they pay significantly different prices for these attributes consistent with their preferences. The results show that buyers have systematic preferences for specific product attributes and that these preferences are implicitly reflected in prices offered in traditional auction markets. The results underscore the need for increased producer supply response to capitalize on the opportunity offered by higher commodity prices by targeting specific attributes and by better timing production and marketing undertakings.

description: To augment the magnetoresistance (MR) ratio of n-type non-degenerate Si-based lateral spin valves (Si-LSVs), we modify the doping profile in the Si layer and introduce a larger local strain into the Si channel by changing a capping insulator. The highest MR ratio of 1.4% is achieved in the Si-LSVs through these improvements, with significant roles played by a reduction in the resistance-area product of the ferromagnetic contacts and an enhancement of the momentum relaxation time in the Si channel.

A dynamical evolution model on the black hole horizon

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: This paper demonstrates a dynamical evolution model of the black hole (BH) horizon. The result indicates that a kinetic area-cells model of the BH's horizon can model the evolution of BH due to the Hawking radiation, and this area-cell system can be considered as an interacting geometrical particle system. Thus the evolution turns into a problem of statistical physics. In the present work, this problem is treated in the framework of non-equilibrium statistics. It is proposed that each area-cell possesses the energy like a microscopic black hole, and has the gravitational interaction with the other area-cells. We consider both a non-interaction ideal system, and a system with small nearest-neighbor interactions, and obtain an analytic expression of the expected value of the horizon area of a dynamical BH. We find that, after a long enough evolution, a dynamical BH with the Hawking radiation can be in equilibrium with a finite temperature radiation field. However, we also find that, the system has a critical point, and when the temperature of the radiation field surrounding the BH approaches the critical temperature of the BH, a critical slowing down phenomenon occurs.

description: Tourism is traveling for recreational, leisure, or business purposes. The World Tourism Organization describes tourists as people who "visit places outside their usual environment for more than twenty-four hours and not more than one consecutive year for leisure, business and other purposes”. Tourism is vital for many countries and many island nations due to the large revenues for businesses with the opportunity for employment in the industries associated with tourism. Over time, an ever increasing number of destinations have opened up and invested in tourism development, turning modern tourism into a key driver for socio-economic progress through the creation of jobs and enterprises, infrastructure development and the export revenues earned. United Nations World Tourism Organization (UNWTO) (2010) reports that tourism has experienced continued expansion and diversification over the past six decades, to become one of the largest and fastest growing economic sectors in the world. Over this period, several new destinations and variants of tourism have emerged. Some of these variants include agrotourism, food or culinary tourism, educational tourism, sports tourism and several others. Despite the world economic meltdown in the past few years, the UNWTO 2020 tourism forecast projects continuous growth in world tourism. UNWTO projects 282 million arrivals to the Americas and this suggest great opportunity for economic growth that would be provided by the expected demand from tourism. Telfer and Wall (1996) showed the competition between tourism and food production to include land, labor and capital symbiosis where both sectors mutually benefit from each other. United States Department of Agriculture’s Foreign Agricultural Service (2011) reports that the tourist industry in the Caribbean is growing. The growth has created an increased demand for food which the region has not been able to meet and subsequently increased US food export to the Caribbean to capture tourists’ revenues. This paper suggests that an increase in food production will capture more tourism revenue in the region. The paper uses a two-stage linear model to estimate the relationship between value-added food production and tourism in the Caribbean. The results show a backward linkage between local food production and tourism in the region. The paper suggests policies that will encourage food production, value added food production and create agricultural tourism and culinary tourism, which are unique niches in the tourism industry.

description: The objectives of this work are to describe and carry out the mechanical recycling process with the medicine blisters. Blister is the medicine carton used by the pharmaceutical industry, which is formed by a Polyvinyl Chloride (PVC) and metal aluminum casing. Its main function is to prolong the shelf life of the medicine, store it and allow it to be transported safely until the moment of consumption. As a consequence of the wide demand for medicines used by the population, a considerable quantity of blisters is also discarded, but they do not have a correct designation for their disposal and, therefore, end up in the common waste, where they are destined for landfills and incinerated, generating new compounds that are toxic and harmful, since they re-enter the environment and, consequently, the daily life of society. The methodology for the elaboration of the project consists of an experimental technical procedure, having as its initial stage the bibliographic survey and, following the steps of extrusion, injection of the test bodies composed of 10, 20 and 30% of blister next to the flexible PVC, for comparison purposes and performance of tests including water absorption test, hardness, density, flammability, conductivity and tensile tests. As a result, the material obtained showed high flame resistance, impermeability and excellent elasticity, allowing wide applicability, such as: soles, replacement of thermoset rubbers, coatings and parts of the construction industry.

description: Food security remains a big challenge in this world but mostly for the undeveloped countries. However, while these countries have to face the system of globalization with more and more rigorous rules, their population has to get enough food to assure the livelihood. Haiti is one of the poorest countries in the world and it has the challenge to feed approximately 10 million people according to World Bank and, between 2.5 and 3.3 million Haitians are estimated to be food insecure according to World Food Program (WFP). This study therefore used a number of models to assess the Food Security situation in Haiti. The main objective of this study was to assess the Food Security situation in Haiti and determine the opportunities for agribusiness development through an import substitution initiative. The following models were used for estimation: 1. The food and nutritional gap 2. The “safety-net” criterion 3. The “nutrition based target” 4. The relation between the international trade and food security using a. the Cereal Supply Indicator (SI) b. the Food Import Capacity Indicator (ICI) Based on the Food Security situation, the study also found investment possibilities which can be used to remedy to the problem.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The composition of Van-der-Waals heterostructures is conclusively determined using a hybrid evaluation scheme of data acquired by optical microspectroscopy. This scheme deploys a parameter set comprising both change in reflectance and wavelength shift of distinct extreme values in reflectance spectra. Furthermore, the method is supported by an accurate analytical model describing reflectance of multilayer systems acquired by optical microspectroscopy. This approach allows uniquely for discrimination of 2D materials like graphene and hBN and, thus, quantitative analysis of Van-der-Waals heterostructures containing structurally very similar materials. The physical model features a transfer matrix method which allows for flexible, modular description of complex optical systems and may easily be extended to individual setups. It accounts for numerical apertures of applied objective lenses and a glass fiber which guides the light into the spectrometer by two individual weighting functions. The scheme is proven by highly accurate quantification of the number of layers of graphene and hBN in Van-der-Waals heterostructures. In this exemplary case, the fingerprint of graphene involves distinct deviations of reflectance accompanied by additional wavelength shifts of extreme values. In contrast to graphene the fingerprint of hBN reveals a negligible deviation in absolute reflectance causing this material being only detectable by spectral shifts of extreme values.

description: Globular clusters offer ideal laboratories to test the predictions of stellar evolution. When doing so with spectroscopic analyses during the 1990s, however, the parameters we derived for hot horizontal branch stars deviated systematically from theoretical predictions. The parameters of cooler, A-type horizontal branch stars, on the other hand, were consistent with evolutionary theories. In 1999, two groups independently suggested that diffusion effects might cause these deviations, which we verified subsequently. I will discuss these observations and analyses and their consequences for interpreting observations of hot horizontal branch stars.

description: We study the renormalized energy-momentum tensor of gravitons in a de Sitter space-time. After canonically quantizing only the physical degrees of freedom, we adopt the standard adiabatic subtraction used for massless minimally coupled scalar fields as a regularization procedure and find that the energy density of gravitons in the E(3) invariant vacuum is proportional to H^4, where H is the Hubble parameter, but with a positive sign. According to this result the scalar expansion rate, which is gauge invariant in de Sitter space-time, is increased by the fluctuations. This implies that gravitons may then add to conformally coupled matter in driving the Starobinsky model of inflation.

description: Cassava as a root crop has a short storage life is a good source of energy but is low in protein. In the midst of high wheat grain prices, the use of cassava flour for bakery products is being promoted, though the very low protein content of cassava is of some concern. As a means of increasing the protein content of cassava flour, the addition of soy flour to form the composite flour was employed. This study evaluated the quality characteristics of muffins baked from high quality wheat/cassava/soy composite flours. The M Mex 59 cassava tubers were processed into flour. Three composite flour blends were prepared with 40%, 50% and 60% cassava flour with 10% soy flour. Physico-chemical analysis and sensory evaluation by focus group and hedonic scoring were conducted on muffins from each of the composite flour blends and 100% wheat flour as the control muffin. The protein content, moisture content, ash content, texture, muffin height and colour of the muffins were measured. A focus group evaluated the sensory difference of the muffins and sensory acceptability was determined using untrained participants (n=51). Results showed that the protein content of the composite flour was significantly affected by the addition of cassava flour and soy flour. Muffin colour progressively darkened as cassava flour level increased. Changes in the muffin height were not significantly different (P>0.05). Increasing cassava flour levels resulted in a reduction of the hardness (mm/3 sec) of the muffins from 9.00 to 14.57 with substitution of 50% of cassava flour. From the focus group evaluation, the muffins from composite blend 50% wheat/40% cassava/ 10% soy were most preferred and were significantly different for taste (P<0.01) and after-taste(P<0.05). Appearance, texture, volume and overall appearance scores of the 50%wheat/40%cassava/10%soy muffins did not differ significantly on comparison to 100% wheat flour. The addition of cassava flour and soy flour positively affected the quality characteristics of the composite flour muffins.

To evaluate the needed diagrams the large mass expansion procedure is used. The obtained contributions are negative in most of the regions of the parameter space and partly compensate the positive O(alpha_s^2) contribution calculated earlier.

description: Ground based optical telescopes are seriously affected by atmospheric turbulence induced aberrations. Understanding properties of these aberrations is important both for instruments design and image restoration methods development. Because the point spread function can reflect performance of the whole optic system, it is appropriate to use the point spread function to describe atmospheric turbulence induced aberrations. Assuming point spread functions induced by the atmospheric turbulence with the same profile belong to the same manifold space, we propose a non-parametric point spread function -- PSF-NET. The PSF-NET has a cycle convolutional neural network structure and is a statistical representation of the manifold space of PSFs induced by the atmospheric turbulence with the same profile. Testing the PSF-NET with simulated and real observation data, we find that a well trained PSF--NET can restore any short exposure images blurred by atmospheric turbulence with the same profile. Besides, we further use the impulse response of the PSF-NET, which can be viewed as the statistical mean PSF, to analyze interpretation properties of the PSF-NET. We find that variations of statistical mean PSFs are caused by variations of the atmospheric turbulence profile: as the difference of the atmospheric turbulence profile increases, the difference between statistical mean PSFs also increases. The PSF-NET proposed in this paper provides a new way to analyze atmospheric turbulence induced aberrations, which would be benefit to develop new observation methods for ground based optical telescopes.

description: Biological control measures to prevent or reduce Agrobacterium vitis-caused losses in grapevine cultures are a worldwide increasing challenge. In the present study, tumour development in grapevine (Vitis vinifera L.) was induced in the sensitive cv. Kerner by infection with Agrobacterium vitis strain K306, carrying the p35Sgus-int plasmid with the gus gene as marker for transformation by the wild-type T-DNA. Pre-inoculation with the non-tumorigenic A. vitis strain F2/5 prevented tumour induction by K306(p35gus-int). Strain M1154, a Tn5 mutant of F2/5 in the luxR-like aviR gene, partially reduced the biocontrol efficiency compared to the wild-type F2/5. GUS-labelling by K306gus was poor in grapevine in contrast to A. tumefaciens 281(p35gus-int)-induced tumours in Arabidopsis, indicating plant species-dependent variable gus expression. To use the more reliable direct mRNA expression assay by RTPCR, a new experimental plant/A. vitis system was established with Ricinus communis as model plant. Ricinus/A. vitis galls were available within one week after K306gus inoculation, reached diameters up to 5 cm, and contained more abundant GUS staining. An additional transformation marker, mRNA expression of the T-DNA-located iaaM oncogene, coding auxin synthesis, was apparent only in tumours induced by the wild-type A. vitis strain K306 in the absence of the gus construct, which is under the control of the strong 35S CaMV promoter. F2/5 pre-inoculation suppressed GUS staining and gus mRNA expression. DAPI staining revealed the loss of vital fluorescent cell nuclei in F2/5-inoculated grapevine tissue and thus inhibition of any successful T-DNA transfer into host cell nuclei. Differentiation of typical circular vessels in globular vascular bundles in M1154-pretreated galls suggests interference with plant auxin metabolism. In conclusion, together with successfully establishing a new experimental model system, Ricinus/A. vitis, pre-treatment of host tissue with the non-pathogenic strain F2/5 resulted in preventing the integration and expression of the oncogenic T-DNA of A. vitis strains by locally necrotizing host cell nuclei.

description: The recent economic turmoil has caused several countries to abandon the tenets of free trade and erect barriers in perceived self-interest. China tightened imports on food and banned Irish pork imports. India banned Chinese toys and Argentina tightened licensing requirements on textiles, auto parts and leather goods. The United States is subsidizing automakers and creating roadblocks to Mexican trucks using American roads. The countries that have taken those steps argue that free and unfettered trade that characterizes many free trade agreements leads to increase job losses. Proponents of free trade argue that such agreements promote strategic relationships and enhance social welfare and economic growth. Against this back drop whether the US should continue to pursue trade agreements is surely not trivial. The paper examines this question from the perspective of New Jersey agricultural producers. The study uses data from the 2005 National Agricultural Food and Public Policy Preference Survey. Twenty seven states participated in the survey and each state was given data relevant to that state. The New Jersey component of survey was mailed to 700 randomly selected farm operators. This number represented approximately 7% of all the farm operators in the state. A total of 162 farm operators responded to the survey, giving a response rate of 23%. However, only 141 responses were usable, resulting in a usable responsive rate of about 20%. That rate compares to the national useable rate of 24%. The paper hypothesizes that farm and ranch operator preferences regarding trade agreements are influenced by such factors as age, farm sales, income, education, and tenure or duration of farm ownership. In particular the paper hypothesizes that there exists a positive relationship between those variables and the dependent variable, i.e. whether the US should continue to pursue trade agreements. To test that hypothesis the paper uses logistic regression. The results show a positive relationship between the dependent variable and age, tenure, income and education but a negative relationship between the dependent variable and sales. The negative relationship with sales is surprising. One would expect agricultural producers to look favorably on the prospects of free trade opening foreign markets for agricultural goods.

description: The low temperature electron-phonon (e-ph) relaxation near the surface of noble metals, Cu and Ag, is studied by using the density-functional theory approach. The appearance of the surface phonon mode can give rise to a strong enhancement of the Eliashberg function at low frequency $ω$. Assuming the Eliashberg function proportional to the square of $ω$ in the low frequency limit, the e-ph relaxation time obtained from the surface calculations is shorter than that from the bulk calculation. The calculated e-ph relaxation time for the former is in agreement with a recent experiment for thin films.

description: Significant health improvements have been noted in Central American and Caribbean countries in the past three decades. The changes have been attributed to improved nutrition and a decline of infectious diseases. However, few studies have attempted to quantify the factors influencing health status in these countries. In this paper, we developed a health production function for 18 Central American and Caribbean countries using panel data. We developed Ordinary Least Squares (OLS), random and fixed effects models to determine the factors affecting health status. Health status represented by life expectancy was expressed as a function of socioeconomic and environmental factors such as income, carbon dioxide (CO2) emission, healthcare expenditure, access to sanitary facilities and clean water, education, recorded AIDS cases, mortality rate due to heart diseases, protein supply, food imports and number of television sets. The random effects model was selected because of its high R2 of 0.83 which means that 83 percent of the variation of the dependent variables is explained by the variation of the independent variables, and the number of significant variables with anticipated signs. The random effects model showed that GDP per capita, GDP per capita2, education, the recorded number of AIDS cases, the interaction between portable water and access to improved sanitation, protein supply and food imports influenced health status. GDP per capita squared negatively influenced health status which means that the region will attain a point where increases in income will reduce the health status of its people. Health policymakers must critically examine the results to determine optimal points of socioeconomic and environmental variable contributions in promoting health care status in these countries.

description: The objectives of this work are to describe and carry out the mechanical recycling process with the medicine blisters. Blister is the medicine carton used by the pharmaceutical industry, which is formed by a Polyvinyl Chloride (PVC) and metal aluminum casing. Its main function is to prolong the shelf life of the medicine, store it and allow it to be transported safely until the moment of consumption. As a consequence of the wide demand for medicines used by the population, a considerable quantity of blisters is also discarded, but they do not have a correct designation for their disposal and, therefore, end up in the common waste, where they are destined for landfills and incinerated, generating new compounds that are toxic and harmful, since they re-enter the environment and, consequently, the daily life of society. The methodology for the elaboration of the project consists of an experimental technical procedure, having as its initial stage the bibliographic survey and, following the steps of extrusion, injection of the test bodies composed of 10, 20 and 30% of blister next to the flexible PVC, for comparison purposes and performance of tests including water absorption test, hardness, density, flammability, conductivity and tensile tests. As a result, the material obtained showed high flame resistance, impermeability and excellent elasticity, allowing wide applicability, such as: soles, replacement of thermoset rubbers, coatings and parts of the construction industry.

description: A key for person re-identification is achieving consistent local details for discriminative representation across variable environments. Current stripe-based feature learning approaches have delivered impressive accuracy, but do not make a proper trade-off between diversity, locality, and robustness, which easily suffers from part semantic inconsistency for the conflict between rigid partition and misalignment. This paper proposes a receptive multi-granularity learning approach to facilitate stripe-based feature learning. This approach performs local partition on the intermediate representations to operate receptive region ranges, rather than current approaches on input images or output features, thus can enhance the representation of locality while remaining proper local association. Toward this end, the local partitions are adaptively pooled by using significance-balanced activations for uniform stripes. Random shifting augmentation is further introduced for a higher variance of person appearing regions within bounding boxes to ease misalignment. By two-branch network architecture, different scales of discriminative identity representation can be learned. In this way, our model can provide a more comprehensive and efficient feature representation without larger model storage costs. Extensive experiments on intra-dataset and cross-dataset evaluations demonstrate the effectiveness of the proposed approach. Especially, our approach achieves a state-of-the-art accuracy of 96.2%@Rank-1 or 90.0%@mAP on the challenging Market-1501 benchmark.

Perfect State Transfer, Effective Gates and Entanglement Generation in Engineered Bosonic and Fermionic Networks

description: We show how to achieve perfect quantum state transfer and construct effective two-qubit gates between distant sites in engineered bosonic and fermionic networks. The Hamiltonian for the system can be determined by choosing an eigenvalue spectrum satisfying a certain condition, which is shown to be both sufficient and necessary in mirror-symmetrical networks. The natures of the effective two-qubit gates depend on the exchange symmetry for fermions and bosons. For fermionic networks, the gates are entangling (and thus universal for quantum computation). For bosonic networks, though the gates are not entangling, they allow two-way simultaneous communications. Protocols of entanglement generation in both bosonic and fermionic engineered networks are discussed.

description: This paper examines the problem of fluctuations in the prices of main agricultural products such as cereals, potatoes, sugar beet and oilseed in the period 1989-2012. The paper presents the changes in prices of major agricultural products in constant price term from 2012. Results show, that after 1989 was a sharp decline in the prices of almost all basic agricultural products. In the least he concerned the rape and the slaughter livestock veal, in the reference to which a rise in prices was recorded in 1990. In the period of examinations were recorded a few price bottoms and hills, including the biggest hole taking place in 1991, in which the government took multifaceted action stabilizing prices of outputs among others by the central import and enabling the individual transport of ready food. The essential slump of prices of outputs took place also in years of the strong economic recession in 2009 and 2010, which the return to upturns was taken note after.

description: The paper revisits recently revealed regimes of the "nonconventional synchronization" in systems of coupled bi-stable Van der Pol oscillators. These regimes are characterized by periodic (or quasiperiodic) almost complete energy exchanges between the coupled oscillators. In the paper it is demonstrated that such responses correspond to synchronization of the modulation amplitudes between symmetric and antisymmetric modes of the system, with persistent phase drift. This observation substantially simplifies the treatment, reduces the dynamics to simple phase cylinder and allows to reveal a rich set of global and local bifurcations of limit cycles and tori in the system. Among other findings, one encounters an unexpected regime of nonstationary asymmetric synchronization.

description: The showers of cosmic rays entering the Earth's atmosphere are main sources of information on cosmic rays and are also believed to provide information on elementary interactions at energies not accessible to accelerators. In this context we would like first to remind the role of inelasticity K and elementary cross section $σ$ and then argue that similar in importance are fluctuations of different observables. The later will be illustrated by multiplicity fluctuations in hadronic and nuclear collisions.

description: The paper presents an analysis of the demographic characteristics of potential changes in mountainous communes in Poland between 2002 and 2012. Using Hellwig’s taxonomic measure, 94 communes were divided into three classes regarding a level of demographic potential development. Communes in the class of a relatively high level of demographic development were concentrated in the southern part of Małopolskie Voivodship. On the other hand, mountainous communes of Podkarpackie Voivodship and of the north-eastern Dolnośląskie Voivodship can be described as problematic in terms of the demographic situation.

description: Magnetic field dependence of low temperature specific heat of spinel oxide superconductor LiTi_2O_4 has been elaborately investigated. In the normal state, the obtained electronic coefficient of specific heat gamma_n = 19.15 mJ/mol K2, the Debye temperature is 657 K and some other parameters are compared with those reported earlier. The superconducting transition at Tc ~ 11.4 K is very sharp (DeltaTc ~ 0.3 K) and the estimated delataC/gamma_nTc is ~ 1.78. In the superconducting state, the best fit of data leads to the electronic specific heat C_es/Gamma_nTc = 9.87 exp (-1.58 Tc/T) without field and gamma(H) ~ H^0.95 with fields. In addition, Hc2(0) ~ 11.7 T, Hc(0) ~ 0.32 T, xi_GL(0) ~ 5.5 nm, lambda_GL(0) ~ 160 nm, and Hc1(0) ~ 26 mT are estimated from Werthamer-Helfand-Hohenberg (WHH) theory or other relevant relations. All results from the present study indicate that LiTi2O4 can be well described by a typical type-II, BCS-like, moderate coupling, and fully gapped superconductor in the dirty limit. It is further suggested that LiTi2O4 is a moderately electron-electron correlated system.
