description: In this paper, joint resource allocation and power control for energy efficient device-to-device (D2D) communications underlaying cellular networks are investigated. The resource and power are optimized for maximization of the energy efficiency (EE) of D2D communications. Exploiting the properties of fractional programming, we transform the original nonconvex optimization problem in fractional form into an equivalent optimization problem in subtractive form. Then, an efficient iterative resource allocation and power control scheme is proposed. In each iteration, part of the constraints of the EE optimization problem is removed by exploiting the penalty function approach. We further propose a novel two-layer approach which allows to find the optimum at each iteration by decoupling the EE optimization problem of joint resource allocation and power control into two separate steps. In the first layer, the optimal power values are obtained by solving a series of maximization problems through root-finding with or without considering the loss of cellular users' rates. In the second layer, the formulated optimization problem belongs to a classical resource allocation problem with single allocation format which admits a network flow formulation so that it can be solved to optimality. Simulation results demonstrate the remarkable improvements in terms of EE by using the proposed iterative resource allocation and power control scheme.

description: Improper design and maintenance of stormwater ponds (SWPs) may lead to hypoxic conditions, poor water quality and the production of hydrogen sulfide (H2S). The objective of this study is to develop a comprehensive understanding of hypoxic conditions of SWPs, with a focus on the potential for H2S production and emission. This study was conducted at two retention SWPs in Ottawa, Canada; a problematic pond with the propensity for H2S emission and a reference pond that did not demonstrate H2S emission. The investigation illustrated a significant impact of low dissolved oxygen (DO) concentrations, hypoxic conditions, on the concentration of total sulfides in the water column. Both ponds were shown to periodically experience hypoxic conditions at depth, especially during summer periods with less precipitation and across longer periods of winter, ice-covered conditions. The problem pond, however, was shown to experience lower DO and longer hypoxic conditions than the reference pond in both non-ice-covered and ice-covered conditions due to greater depth and a longer hydraulic retention time. Hypoxic conditions were initiated at the deepest locations in the problem pond and subsequently were spread across the entirety of the pond under winter, ice-covered conditions. Algal biomass (Chlorophyll-a) and soluble biochemical oxygen demand concentrations were shown to not likely be significant factors in the development of hypoxia in the H2S-generating pond. Algal blooms of colonial Chrysophyceae, Synura, a known mixotroph, were observed during ice-covered conditions in the problem pond possibly due to stress-coping mechanisms of algae.

description: We present an analysis of photometric observations of the eclipsing novalike variable DW UMa made by the CBA consortium between 1999 and 2015. Analysis of 372 new and 260 previously published eclipse timings reveals a 13.6 year period or quasi-period in the times of minimum light. The seasonal light curves show a complex spectrum of periodic signals: both positive and negative superhumps, likely arising from a prograde apsidal precession and a retrograde nodal precession of the accretion disc. These signals appear most prominently and famously as sidebands of the orbital frequency but the precession frequencies themselves, at 0.40 and 0.22 cycles per day, are also seen directly in the power spectrum. The superhumps are sometimes seen together and sometimes separately. The depth, width and skew of eclipses are all modulated in phase with both nodal and apsidal precession of the tilted and eccentric accretion disc. The superhumps, or more correctly the precessional motions which produce them, may be essential to understanding the mysterious SW Sextantis syndrome. Disc wobble and eccentricity can both produce Doppler signatures inconsistent with the true dynamical motions in the binary, and disc wobble might boost the mass-transfer rate by enabling the hot white dwarf to directly irradiate the secondary star.

description: No abstracts are to be cited without prior reference to the author.The anchoveta, Engraulis ringen, occupies a wide latitudinal range (4 - 42 oS) throughout which the environmental conditions at the spawning areas change markedly. Some environmental characteristics known to vary with latitude are temperature, wind stress, upwelling intensity and turbulence (Bakun 1996, Castro et al. 2001). All these factors may affect either directly or indirectly the chances of survival of early life stages of fish. Temperature affects directly metabolic rates, development, growth rates and hence, duration of these vulnerable young stages (Houde 1987, 1989). Wind stress affects the water column by inducing changes in upwelling intensity, which in turn affect egg and larval transport, biological productivity of the water and food concentrations for young larvae (Cury & Roy 1989, Bakun 1996). Wind intensity also modulates the water column stability and encounter rates between fish larvae and their prey (Lasker 1975, Sundby 1996).

description: We follow the passage from complex amplitude bistability to phase bistability in the driven dissipative Jaynes-Cummings oscillator. Quasidistribution functions in the steady state are employed, for varying qubit-cavity detuning and drive parameters, in order to track a first-order dissipative quantum phase transition up to the critical point marking a second-order transition and spontaneous symmetry breaking. We demonstrate the photon blockade breakdown in the dispersive regime, and find that the coexistence of cavity states in the regime of quantum bistability is accompanied by pronounced qubit-cavity entanglement. Focusing on the role of quantum fluctuations in the response of both coupled quantum degrees of freedom (cavity and qubit), we move from a region of minimal entanglement in the dispersive regime, where we derive analytical perturbative results, to the threshold behaviour of spontaneous dressed-state polarization at resonance.

description: No abstracts are to be cited without prior reference to the author.Recruitment of striped bass is correlated with the magnitude of spring freshwater flow into upper Chesapeake Bay (R2 = 0.50). Processes driving the relationship are poorly known. Two approaches were followed to identify and explain the processes: 1) a multidisciplinary study in 2001-2003 focused on larval-stage ecology and bio-physical interactions within the estuarine turbidity maximum (BITMAX Project), and 2) analysis of juvenile-stage growth and survival based on BITMAX collections and on longer-term surveys. Ichthyoplankton surveys were conducted in a moderate recruitment year (2001), a poor recruitment year (2002), and a very strong recruitment year (2003).

description: A ocorrência de bolhas de plasma, a saber, irregularidades na distribuição de densidade eletrônica no meio ionosférico, implica no aparecimento de cintilações, que são mudanças acentuadas na amplitude e/ou fase de ondas eletromagnéticas. Ao atravessar tais irregularidades ionosféricas, sinais de GPS, por exemplo, sofrem essas mudanças, o que provoca erro de leitura de posicionamento. O período de cintilações em Natal inicia-se em setembro e termina em abril. Fora desse intervalo, entretanto, é possível se verificar, na mesma localidade, o surgimento extraordinário desse tipo de fenômeno. Na noite do dia 08 de junho de 2011, por exemplo, registrou-se na Estação de Natal uma cintilação, sendo esta, então, o foco deste estudo. Análise das condições magnéticas e elétricas da magnetosfera desta data, além das dos dias 07 e 09 do mesmo mês, podem explicar a origem das bolhas que provocaram estas cintilações. O estudo aborda as variações dos índices AE, analisando a possibilidade de dínamo perturbado como fator causal, bem como a taxa de variação do índice Dst, como variável que pode indicar a penetração de campo elétrico na faixa próxima ao equador geomagnético. Também são analisados dados fornecidos pelo satélite ACE, a saber: campo magnético interplanetário e velocidade do plasma solar em choque com a magnetosfera da Terra, parâmetros úteis para o cálculo do campo elétrico interplanetário, possível agente influenciador das bolhas do dia 08. O trabalho ainda apresenta uma análise do registro de um campo elétrico na região equatorial, durante esse período, com indício de influência de perturbação magnética, apontando para a ocorrência de uma atípica deriva vertical da camada F durante o crepúsculo.

description: Little research has focused on extended therapy for cows with clinical mastitis during lactation. Ceftiofur should be effective against a wide range of mastitis pathogens including gram-positive and gram-negative bacteria. It could be considered as a reasonable choice for treatment of clinical mastitis. The objective of the present study was to determine if extended therapy would increase cure rates of a ceftiofur treatment for non-acute clinical mastitis, for all bacteria and more specifically for Staphylococcus aureus and streptococci. The hypothesis was that extended therapy would enhance the cure rate of ceftiofur for non-acute clinical mastitis.

description: In this paper, energy efficient power control for the uplink two-tier networks where a macrocell tier with a massive multiple-input multiple-output (MIMO) base station is overlaid with a small cell tier is investigated. We propose a distributed energy efficient power control algorithm which allows each user in the two-tier network taking individual decisions to optimize its own energy efficiency (EE) for the multi-user and multi-cell scenario. The distributed power control algorithm is implemented by decoupling the EE optimization problem into two steps. In the first step, we propose to assign the users on the same resource into the same group and each group can optimize its own EE, respectively. In the second step, multiple power control games based on evolutionary game theory (EGT) are formulated for each group, which allows each user optimizing its own EE. In the EGT-based power control games, each player selects a strategy giving a higher payoff than the average payoff, which can improve the fairness among the users. The proposed algorithm has a linear complexity with respect to the number of subcarriers and the number of cells in comparison with the brute force approach which has an exponential complexity. Simulation results show the remarkable improvements in terms of fairness by using the proposed algorithm.

description: An instability of a liquid droplet traversed by an energetic ion is explored. This instability is brought about by the predicted shock wave induced by the ion. An observation of multifragmentation of small droplets traversed by ions with high linear energy transfer is suggested to demonstrate the existence of shock waves. A number of effects are analysed in effort to find the conditions for such an experiment to be signifying. The presence of shock waves crucially affects the scenario of radiation damage with ions since the shock waves significantly contribute to the thermomechanical damage of biomolecules as well as the transport of reactive species. While the scenario has been upheld by analyses of biological experiments, the shock waves have not yet been observed directly, regardless of a number of ideas of experiments to detect them were exchanged at conferences.

description: Bovine neonates have a naïve immune system and must initially rely on the absorption and passive transfer of maternally derived immunoglobulins (lg) ingested in colostrum. Acceptable passive transfer (APT) is defined as a serum IgG≥10 mg/mL between 24-48 hours of age. A serum total protein (STP) cutpoint of 5.0 or 5.2 g/dl is commonly used to predict APT for calves fed lacteal-derived whole colostrum (Calloway et al, 2002). However, many producers now feed powdered commercial colostrum replacers (CR). Some CR products contain lacteal-derived (LD) lg while others contain lg derived from spray-dried plasma (PD). Research is needed to determine the best STP cutpoint to predict APT for calves fed either LD or PD CR products. The objectives of this study were to 1) describe levels of passive transfer and 2) determine the relationship between STP and IgG for neonatal calves fed a commercially available LD CR or PD CR product, respectively.

description: Nanosized titanium dioxide (TiO2) has been investigated in numerous studies on genotoxicity, including comet assay endpoints and oxidatively damaged DNA in cell cultures and animal models. The results have been surprisingly mixed, which might be attributed to physico-chemical differences of the tested TiO2. In the present review, we assess the role of certain methodological issues and publication bias. The analysis shows that studies on DNA strand breaks without proper assay controls or very low intra-group variation tend to show statistically significant effects. Levels of oxidatively damaged DNA, measured by the enzyme-modified comet assay, tend to show no effect in studies that have not included proper assay controls or they have uncertainty about the measurement. In addition, there are indications of publication and reporting bias. Nevertheless, the analysis shows that Aeroxide P25 generates DNA strand breaks in a concentration-dependent manner, which is not dependent on the duration of exposure. The standard comet assay seems to be able to discriminate between the genotoxicity of different types of TiO2, where anatase TiO2 seems to be the form with strongest genotoxic potential. Cell culture studies also demonstrate increased levels of oxidatively damaged DNA after exposure to TiO2. There are relatively few studies on animal models where DNA strand breaks and oxidatively damaged DNA have been tested with reliable methods. Collectively, this review shows that exposure to nanosized TiO2 is associated with genotoxicity in cells, whereas there are still too few reliable studies to assess the genotoxic potential in animal models.

description: No abstracts are to be cited without prior reference to the author.Two consecutive multidisciplinary surveys covering the N/NW of the Iberian shelf and slope were carried out during spring 2000 (28 March to 15 April and 25 April to 15 May) in order to obtain T0 and T1 observations in mackerel larvae abundance and biological parameters related to age and birthdate (e.g. size and otoliths). In addition, other biological and hydrographic variables were also sampled to describe and relate the environmental conditions to larvae distribution and survival. Absolute abundances of mackerel larvae were similar in both surveys with a total of 916 and 988 larvae captured respectively. Only a few larvae were caught off the Galician coast and the remainder were spread along the Cantabrian coast. Larval size and age structure showed that larvae found during the second survey were younger than larvae captured during the first one. The later birthdate analysis from otoliths of mackerel juveniles caught between July and October 2000 and with a length range of 121-202 mm LS confirmed the nonexistence of survivors from the early spring spawns. The abundance of one-year-old mackerel estimated from the acoustic survey in 2001 was the lowest observed from 1999 to 2003. The causes of this failure or null survival from the early spawns in that year can be found in the special meteorological and oceanographic conditions in spring 2000, with two abnormal strongwind events in April after a relatively calm March. Mackerel larval survival may be strongly determined by environmental variables, strong wind conditions in this case. Strong turbulence generated by high wind speed has a negative effect on larval survival by desegregating food and larvae patches, and also on recruitment. This is consistent with the hypothesis that stability of the upper water column influences recruitment but the possible advection of larvae towards unfavourable areas must also be considered.

description: Failure of passive transfer (FPT), defined as serum IgG <10 mg/mL at 24-48 hours of age, is an important problem on dairy farms. If an adequate supply of high-quality colostrum is not available, producers may feed a colostrum replacer (CR) product. However, studies are lacking to compare the effects of different CR products on passive transfer and calf health during the preweaning period. The objectives of this study were to describe the effect of feeding two different commercially available CR products, one lacteal-derived (LD CR) and one plasma-derived (PD CR) on 1) serum IgG levels during the first nine weeks, 2) the risk for development of scours, and 3) the risk for fecal shedding of common enteric pathogens in the first 14 days of age.

description: Early studies have suggested that bacteria in colostrum may interfere with passive absorption of immunoglobulins (lg) in newborn calves (James et al, 1981), and recent studies reported that calves fed pasteurized colostrum had improved passive transfer of IgG versus calves fed fresh colostrum (Johnson et al, 2007; Heinrichs et al, 2009a). However, a recent study reported that colostrum bacteria counts were not associated with IgG absorption (Heinrichs et al, 2009b). Do pathogenic or non-pathogenic bacteria, living or dead, truly interfere with lg absorption? Bovamine® (Nutrition Physiology Company, LLC, Overland Park, KS) is a direct-fed microbial (DFM or probiotic) containing a patented combination of living Lactobacillus acidophilus ( 1 x 109 cfu/1 g dose) and Propionibacterium freudenreichii (2 x 109 cfu/1 g dose). The study objective was to describe the effect of supplementing colostrum with living or dead DFM on serum total protein (STP) and IgG levels, and apparent efficiency of absorption of IgG (AEA %).

description: Strontium doping transforms manganites of type La(1-x)Sr(x)MnO(3) from an insulating antiferromagnet (x=0) to a metallic ferromagnet (x>0.16) due to the induced charge carriers (holes). Neutron scattering experiments were employed to investigate the effect of Sr doping on a tailor-made compound of composition La(0.7)Sr(0.3)Mn(0.1)Ti(0.3)Ga(0.6)O(3). By the simultaneous doping with Sr2+ and Ti4+ ions the compound remains in the insulating state, so that the magnetic interactions for large Sr doping can be studied in the absence of charge carriers. At TC=215 K there is a first-order reconstructive phase transition from the trigonal R-3c structure to the orthorhombic Pnma structure via an intermediate virtual configuration described by the common monoclinic subgroup P21/c. The magnetic excitations associated with Mn3+ dimers give evidence for two different nearest-neighbor ferromagnetic exchange interactions, in contrast to the undoped compound LaMnyA(1-y)O(3) where both ferromagnetic and antiferromagnetic interactions are present. The doping induced changes of the exchange coupling originates from different Mn-O-Mn bond angles determined by neutron diffraction. The large fourth-nearest-neighbor interaction found for metallic manganites is absent in the insulating state. We argue that the Ruderman-Kittel-Kasuya-Yosida interaction reasonably accounts for all the exchange couplings derived from the spin-wave dispersion in metallic manganites.

description: Catosal® (Bayer, Shawnee Mission, Kansas, USA) is a sterile solution containing 10% butaphosphan and cyanocobalamin (vitamin B12), and is intended to prevent or treat deficiencies of these nutrients. Supplemental vitamin B12 may enhance gluconeogenesis through its role in methylmalonyl-CoAmutase. Phosphorus plays important roles in the hydrogen buffering system in the blood, is a critical component of nucleic acids, and is clinically important due to its role in postparturient paresis in dairy cattle. The objective of this study was to assess the effect of two 25 mL injections of Catosal® on the serum BHBA, calcium, and phosphorus concentrations of cows in the early postparturient period.

description: We analyzed the star HD 171219, one of the relatively bright Be stars observed in the seismo field of the CoRoT satellite, in order to determine its physical and pulsation characteristics. Classical Be stars are main-sequence objects of mainly B-type, whose spectra show, or had shown at some epoch, Balmer lines in emission and an infrared excess. Both characteristics are attributed to an equatorially concentrated circumstellar disk fed by non-periodic mass-loss episodes (outbursts). Be stars often show nonradial pulsation gravity modes and, as more recently discovered, stochastically excited oscillations. Applying the CLEANEST algorithm to the high-cadence and highly photometrically precise measurements of the HD 171219 light curve led us to perform an unprecedented detailed analysis of its nonradial pulsations. Tens of frequencies have been detected in the object compatible with nonradial g-modes. Additional high-resolution ground-based spectroscopic observations were obtained at La Silla (HARPS) and Haute Provence (SOPHIE) observatories during the month preceding CoRoT observations. Additional information was obtained from low-resolution spectra from the BeSS database. From spectral line fitting we determined physical parameters of the star, which is seen equator-on. We also found in the ground data the same frequencies as in CoRoT data. Additionally, we analyzed the circumstellar activity through the traditional method of V/R emission Hα line variation. A quintuplet was identified at approximately 1.113 c/d (12.88 μHz) with a separation of 0.017 c/d that can be attributed to a pulsation degree l~2. The light curve shows six small- to medium-scale outbursts during the CoRoT observations. The intensity of the main frequencies varies after each outburst, suggesting a possible correlation between the nonradial pulsations regime and the feeding of the envelope.

description: No abstracts are to be cited without prior reference to the author.The annual cycle of abundance and vertical distribution of the scyphozoan medusa Aurelia aurita was studied in the Bornholm Basin (central Baltic) in 2002. Seasonal changes in prey composition and predatory impact were investigated by analysing stomach contents. The dominant prey organisms of A. aurita were several cladoceran species (Bosmina coregoni maritima, Evadne nordmanni and Podon spp.). They represented up to 93% of the food organisms. Bivalve larvae and copepods (Centropages hamatus, Temora longicornis, Acartia spp., Pseudocalanus acuspes, Eurytemora hirundoides and Oithona similis) were less frequently found. Nauplii and copepodites I-III were not eaten by the medusae neither were fish eggs and larvae used as prey. Based on average medusae and zooplankton abundance, the predatory impact was very low. In August, when mean abundance of A. aurita was highest, only 0.1% of the copepod and 0.54% of the cladoceran standing stock were eaten per day. However in regions with higher medusae or lower zooplankton abundance up to 8% of the cladoceran standing stock were eaten per day.

description: The geodynamic drivers responsible for the extension mechanisms presently seen in the Aegean Sea and the Hellenic Arc have been promoting scientific debate for decades. Back- arc crustal extension driven by rollback of the underthrusting African slab controls the slow north-south extension active since several tens of million years in the Aegean Sea. Younger fast east-west extension along steep faults trending N-S in the Hellenic Arc seem unrelated to subduction processes; normal faults are not strictly perpendicular to the subduction interface along strike, but instead open radially away from its southernmost tip. We strive to unravel the geodynamic drivers behind the apparently disagreeing extension modes in post- Messinian times by producing tectonic integrations at the scale of the Aegean. We produce integrations at two “zoom levels” (regional, 103-104 km; and tectonic, >105 km) that respect the particularities and complexity of the information of studies at the local-scale (<103 km). First, we included available tectono-morphological, stratigraphic, and structural data onland. We revised and refined these data along the Hellenic Arc with fieldwork observations, as well as with the detailed analysis of satellite imagery and 0.5m-resolution DEMs at key sites. At these key locations, where active extensional tectonics is irrefutable, we mapped Plio- Pleistocene marine basins presently exposed onshore, active faults and marine terraces with unprecedented detail, and produced chi maps to characterize drainage geometry. On a second (still ongoing) step, we aim at integrating bathymetric data, wells and other offshore inputs, such as seismic reflection data, for onshore-offshore correlations and re-mapping of active faults as well as producing paleogeographic reconstructions. In a later step, we will attempt 4D reconstructions at tectonic scale to be used as input for numerical models, hopefully providing a better understanding of the dynamically changing state of stress and derived strain in the Aegean, northeast Mediterranean area and elsewhere.

description: Siderophore receptor proteins (SRP) are iron-regulated proteins shown to be highly conserved between members of the family Enterobacteriaceae, making them novel vaccine targets. Siderophore receptor proteins of Salmonella Newport have been successfully exploited to control Salmonella Newport in the dairy industry for over a decade. This same technology has now been developed to combat Klebsiella mastitis. The objective of this study was to evaluate efficacy of a Klebsiella vaccine based on SRP technology to reduce Klebsiella mastitis in a dairy herd with ongoing disease that was not controlled with JS vaccination. The study was conducted at the Iowa State University (ISU) Dairy in Ames, Iowa.

description: We study the pre-equilibrium dipole response in the charge-asymmetric reaction $^{132}$Sn+$^{58}$Ni at $E_{lab}=10$ MeV/A, within a semi-classical transport model employing effective interactions for the nuclear mean-field. In particular, we adopt the recently introduced SAMi-J Skyrme interactions, whose parameters are specifically tuned to improve the description of spin-isospin properties of nuclei. Within the same framework, we also discuss pre-equilibrium nucleon emission. Our results show that both mechanisms, i.e., pre-equilibrium dipole oscillations and nucleon emission, are sensitive to the symmetry energy below the saturation density $ρ_0$ (in the range $0.6ρ_0-ρ_0$), to the effective mass and to the nucleon-nucleon cross section. Finally, a covariant analysis is applied to study the correlations between the model parameters and observables of experimental interest.

description: Calf-raising operations provide a unique microbial niche where immature intestinal flora, dense animal populations, and frequent application of antimicrobials may facilitate the emergence of antimicrobial resistant pathogens. In the US, producers report that 18% of calves receive an antimicrobial for diarrhea prior to weaning, often with antimicrobials designated as "critically important" to human medicine. The overall objective for this research was to understand the decision criteria for antimicrobial use for calf diarrhea. We hypothesized that selective antimicrobial use is associated with herd-level predictors, including the presence of veterinarian-written treatment protocols and producer attitudes about the impact of antimicrobial use in livestock.

description: Surveys indicate that approximately 20% of US cow-calf operations recognize nursing calf BRD to be a problem, leading to the possibility that important risk factors could be identified by comparing affected herds to appropriately matched unaffected herds. The objective of this study was to determine herd-level risk factors for nursing calf BRD through a matched case-control study of cow-calf operations in 3 US states.

description: The tremendous losses suffered by American investors because of the recent depression have caused the public to pay more attention to investments in general. The "bank holiday" and the moratorium on the payments of cash and loan values held by life insurance companies in the Spring of 1933 have caused policyholders to wonder about the safety and liquidity of their insurance reserves. Texas policyholders have known little of the MODUS OPERANDI of the investment departments of the Texas life insurance companies, nor of the investment philosophy, except in a general way. Little has been known of the results of the investment programs of the Texas insurance companies. The public reports, until recently, have given scarcely any information that could be understood by the average layman. In fact, these reports have been extremely vague to the policyholder without special training in insurance and in accounting fields. This dissertation has for its purpose the presentation and explanation of the philosophy, MODUS OPERANDI, and results obtained during the period from 1927 to 1938 of the investment programs of the Texas life insurance companies together with certain criticism for the betterment of those programs and a clearer presentation of the results to the Board of Insurance Commissioners of Texas, the policyholders, and the public generally

description: Bovine respiratory disease (BRD) diagnosis in feedlots is based on clinical inspection (CI) done once or twice daily by pen-riders or pen-walkers. A diagnosis of BRD is typically established when an animal has visual signs of BRD and a rectal temperature above a threshold (ranging from 103.1 to 104 °F) (39.5 to 40 °C). This diagnostic approach is known to have less than ideal sensitivity (SeCI) and specificity (SpCI). However, accurate estimates of SeCI and SpCI are not available, in part due to the absence of a reference test for antemortem diagnosis of BRO. The objective was to determine the diagnostic accuracy of CI for BRO diagnosis in post-weaned beef calves. The presence of lung lesions at slaughter (LU) was used as an imperfect reference test to determine SeCI and SpCI.

description: The relationship between the universal conductance fluctuation and the weak localization effect in monolayer graphene is investigated. By comparing experimental results with the predictions of the weak localization theory for graphene, we find that the ratio of the elastic intervalley scattering time to the inelastic dephasing time varies in accordance with the conductance fluctuation; this is a clear evidence connecting the universal conductance fluctuation with the weak localization effect. We also find a series of scattering lengths that are related to the phase shifts caused by magnetic flux by Fourier analysis.
