description: Norovirus infection is a leading cause of non-bacterial acute gastroenteritis. This study aimed to analyze the antigenic properties of the VP1 protein of norovirus GII.4 Sydney [P16] circulating in Russia. The analysis was conducted using in silico methods. VP1 amino acid sequence data was used to identify T-helper and T-killer epitopes, linear and conformational B-cell epitopes to assess the conservation of epitopes, and allergenicity of VP1. T cell epitopes with the highest estimated immunogenicity were identified at positions 207-223 and 378-394 in the Sand Pdomains of the protein. The tertiary structure of VP1 was modeled, and 2 linear and 47 conformational B-cell epitopes were identified. In addition to the previously described epitopes, a new putative B-cell epitope was identified at position 307-316 of the P2 subdomain. In silico analysis of the primary and tertiary structure of the norovirus VP1 protein showed that it is not allergenic and has various immunogenic epitopes, potentially capable of inducing Tand B-cell immune responses.

description: Over the past 20 years, significant advances have been made in the understanding of cell and tissue culture in the fields of bioengineering, cell biology, and genetics; however, these achievements have largely focused on mammalian systems. In vitro studies on fish cells and tissues have been relatively limited, but the use of fish cell lines as in vitro models for environmental toxicology, particularly cytotoxicity analysis, has been significant. In addition, cultured cells have been used to study fish parasites and as in vitro models for screening immunostimulants. Skeletal muscle is the most important edible tissue in fish and rapid muscle growth determines the advantages of in vivo aquaculture. The generation of fish muscle cell lines can help to provide a reliable platform for deciphering the mechanism of fish skeletal muscle growth both in vivo and in vitro. In addition, cultured fish meat is a promising technology for animal proteinbased foods and the concept of cell biomass meat from fish needs to be further developed. Our data demonstrated the feasibility of obtaining and culturing sterlet muscle cells in vitro. This study highlights the potential advantages of cell aquaculture over traditional fishing and aquaculture, and the potential applications of fish muscle cell lines in the study of fish skeletal muscle growth and the production of edible cultured fish meat products.
“Forged in Crisis?” Assessing the EU’s Evolving Actorness in Energy Security in Light of Energy Supply Crises

description: This thesis’s purpose is two-fold. First, the primary purpose of this thesis is to explore the EU’s evolving actorness in energy security, seeking to answer how we can understand the main factors that have led to the EU acquiring actorness in energy security. In this context, the thesis builds on the theoretical framework of actorness, informed by the two criteria of decision-making power and capabilities. By applying the method of process-tracing and primarily looking at empirical material from the Commission, the analysis reveals that crises in energy supply are the main driving force behind EU actorness in energy security. Second, the study explores how strategic autonomy is manifested in the EU’s ambitions regarding energy security. The analysis finds that the concept is reflected in the EU’s plan to end its overreliance on Russian energy imports with the help of diversifying, investing in renewables, reducing demand, and developing storage capacity.

description: To assess the risks from viral contamination of drinking-water supplies, there is a clear need for methods to directly detect viral pathogens. In this study, we developed a broad-spectrum immunocapture method for concentration and purification of enteric viruses. The method involved indirect antibody capture (AbCap) of intact viruses followed by release of virion genomic RNA and reverse transcriptase PCR for amplification and oligoprobe hybridization for detection. The procedure involved concentrating enteric viruses from large volumes of water by standard filtration-elution techniques with IMDS filters and 1 liter of 1% beef extract-0.05 M glycine (BE/G) as an eluate. The BE/G eluate was concentrated and purified by polyethylene glycol (PEG) precipitation, Pro-Cipitate (a commercially available protein precipitating reagent) precipitation, and a second PEG precipitation to a volume of approximately 500 mu l. Aliquots of the second PEG precipitate were further processed by RNA extraction, AbCap, or cell culture analysis for infectious viruses. The AbCap method was applied to 11 field samples of fecally contaminated surface water. Of the 11 samples, 9 were positive for enteric viruses by AbCap method 4 of 11 samples were positive for enteric viruses by direct RNA extraction of a small aliquot of the second PEG concentrate; and 4 of 11 samples were positive for enteric viruses by measurement of cell culture infectivity. The results of enteric viruses were compared with those for standard bacterial and coliphage indicators of fecal contamination.
Quantifying the biodegradation of phenanthrene by Pseudomonas stutzeri P16 in the presence of a nonionic surfactant.

description: The low water solubility of polycyclic aromatic hydrocarbons is believed to limit their availability to microorganisms, which is a potential problem for bioremediation of polycyclic aromatic hydrocarbon-contaminated sites. Surfactants have been suggested to enhance the bioavailability of hydrophobic compounds, but both negative and positive effects of surfactants on biodegradation have been reported in the literature. Earlier, we presented mechanistic models of the effects of surfactants on phenanthrene dissolution and on the biodegradation kinetics of phenanthrene solubilized in surfactant micelles. In this study, we combined the biodegradation and dissolution models to quantify the influence of the surfactant Tergitol NP-10 on biodegradation of solid-phase phenanthrene by Pseudomonas stutzeri P16. Although micellized phenanthrene does not appear to be available directly to the bacterium, the ability of the surfactant to increase the phenanthrene dissolution rate resulted in an overall increase in bacterial growth rate in the presence of the surfactant. Experimental observations could be predicted well by the derived model with measured biokinetic and dissolution parameters. The proposed model therefore can serve as a base case for understanding the physical-chemical effects of surfactants on nonaqueous hydrocarbon bioavailability.

description: Schrödinger perturbations of transition densities by singular potentials may fail to be comparable with the original transition density. For instance this is so for the transition density of a subordinator perturbed by any time-independent unbounded potential. In order to estimate such perturbations it is convenient to use an auxilary transition density as a majorant and the 4G inequality for the original transition density and the majorant. We prove the 4G inequality for the $1/2$-stable and inverse Gaussian subordinators, discuss the corresponding class of admissible potentials and indicate estimates for the resulting transition densities of Schrödinger operators. The connection of the transition densities to their generators is made via the weak-type notion of fundamental solution.

description: Overtraining syndrome (OTS) is a condition associated with prolonged dysfunctional adaptation to physical exercise and a long-term imbalance between training and recovery that results in decreased sports performance lasting from several weeks to months with serious consequences for the health of athletes. The problem of diagnosis and prevention of OTS remains relevant, as the diagnosis is often made retrospectively. Currently, no clear reliable biochemical or functional markers for early detection of OTS are described, and the features of pathogenesis of this syndrome remain unclear. The present overview describes the basic theories of OTS development, the main biomarkers and their diagnostic significance, as well as some novel parameters and methods that may be possibly perspective for early detection of OTS.
Exploring The Authoritarian Personality

description: In recent years, not only in the United States has the stability of its democracy been questioned, but all around the world we are witnessing examples of politicians showing authoritarian tendencies who are yet gaining in vote and approval rates – or even assuming the highest-ranking offices. Authoritarian leadership, historically associated with the political right, is well established in literature, but little seems to focus on what personality traits may exist in an authoritarian leader. This paper brings forth the argument that an elite authoritarian personality type, irrespective of political ideology, exists which can get activated under situation-specific circumstances that have measurable effects on the leader’s behavior and rule. To explore this argument, this thesis created a coding scheme of three criteria to identify authoritarian characteristics in an elite, providing evidence for the existence of an elite authoritarian personality type irrespective of political “wing-ness”.

Anoxygenic Photosynthesis and Nitrogen Fixation by a Microbial Mat Community in a Bahamian Hypersaline Lagoon
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: Simultaneous measurements of photosynthesis (both oxygenic and anoxygenic) and N(inf2) fixation were conducted to discern the relationships between photosynthesis, N(inf2) fixation, and environmental factors potentially regulating these processes in microbial mats in a tropical hypersaline lagoon (Salt Pond, San Salvador Island, Bahamas). Major photoautotrophs included cyanobacteria, purple phototrophic bacteria, and diatoms. Chemosystematic photopigments were used as indicators of the relative abundance of mat phototrophs. Experimental manipulations consisted of light and dark incubations of intact mat samples exposed to the photosystem II inhibitor DCMU [3-(3,4-dichlorophenyl)-1,1-dimethylurea], a dissolved organic carbon source (D-glucose), and normal seawater (37(permil)). Photosynthetic rates were measured by both O(inf2) and (sup14)C methods, and nitrogenase activity (NA) was estimated by the acetylene reduction assay. Moderate reductions in salinity (from 74 to 37(permil)) had no measurable effect on photosynthesis, O(inf2) consumption, or NA. CO(inf2) fixation in DCMU-amended samples was (symbl)25% of that in the control (nonamended) samples and demonstrated photosynthetic activity by anoxygenic phototrophs. NA in DCMU-amended samples, which was consistently higher (by a factor of 2 to 3) than the other (light and dark) treatments, was also attributed to purple phototrophic bacteria. The ecological implication is that N(inf2) fixation by anoxygenic phototrophs (purple phototrophic bacteria and possibly cyanobacteria) may be regulated by the activity of oxygenic phototrophs (cyanobacteria and diatoms). Consortial interactions that enhance the physiological plasticity of the mat community may be a key for optimizing production, N(inf2) fixation, and persistence in these extreme environments.

description: The focus of this review is on evaluating the contribution of various regulatory mechanisms of calcium metabolism to the execution of key microglial functions such as patrolling, migration, proliferation, polarization, as well as mitochondrial plasticity and inflammasome assembly. We address current issues on the regulation of calcium homeostasis in microglial cells and microglia-like cells (MLCs). A concise historical overview of microglia and MLCs is provided, followed by an analysis of their functioning in both normal and pathological conditions. We refer to the functional classification of various calcium channels and transporters expressed in the plasma membrane and endoplasmic reticulum of microglia along with elucidation of the mechanisms leading to elevated cytosolic Ca2+ concentrations in microglial cell upon their activation. Then, we discuss the contribution of NAD+-glycohydrolase/CD38 to the regulation of calcium homeostasis in microglia. The review highlights contemporary approaches for manipulating microglial calcium metabolism with potential implications for the treatment of neurodegenerative diseases and neuroinflammation. Additionally, we briefly mention on modern imaging methods for studying calcium signaling in microglia. Thus, we summarize current data that shed the light on the intricate interplay between calcium regulation and microglial function in brain (patho)physiology. It also offers insights into potential therapeutic strategies and visualization techniques in the context of diagnostics and treatment of neurodegenerative disorders and neuroinflammation.

description: Manipulating logic functions via majority operators recently drew the attention of researchers in computer science. For example, circuit optimization based on majority operators enables superior results as compared to traditional logic systems. Also, the Boolean satisfiability problem finds new solving approaches when described in terms of majority decisions. To support computer logic applications based on majority a sound and complete set of axioms is required. Most of the recent advances in majority logic deal only with ternary majority (MAJ- 3) operators because the axiomatization with solely MAJ-3 and complementation operators is well understood. However, it is of interest extending such axiomatization to n-ary majority operators (MAJ-n) from both the theoretical and practical perspective. In this work, we address this issue by introducing a sound and complete axiomatization of MAJ-n logic. Our axiomatization naturally includes existing majority logic systems. Based on this general set of axioms, computer applications can now fully exploit the expressive power of majority logic.

description: Bayesian state and parameter estimation have been automated effectively in a variety of probabilistic programming languages. The process of model comparison on the other hand, which still requires error-prone and time-consuming manual derivations, is often overlooked despite its importance. This paper efficiently automates Bayesian model averaging, selection, and combination by message passing on a Forney-style factor graph with a custom mixture node. Parameter and state inference, and model comparison can then be executed simultaneously using message passing with scale factors. This approach shortens the model design cycle and allows for the straightforward extension to hierarchical and temporal model priors to accommodate for modeling complicated time-varying processes.

description: The Republic of Sakha (Yakutia), located in the northeastern part of Russia, is characterized by an extremely cold climate, to which the indigenous people is adapted. Over the past decades, there has been a significant increase of the incidence of type 2 diabetes mellitus (T2DM) among the indigenous population. It is known that polymorphisms of the mitochondrial genome, in particular, the 16189C variant of hypervariable segment I (HVS-I), may contribute to the development of T2DM. The aim of the study was to assess the association of mitochondrial DNA (mtDNA) HVS-I polymorphisms with the type 2 diabetes mellitus in the Sakha (Yakut) population. Sequencing of HVS-I mtDNA in 102 patients with T2DM and 101 non-diabetic controls revealed 67 haplotypes and 64 SNP variants. There was no statistically significant difference in the frequencies of detected HVS-I polymorphisms and haplotypes between the two groups, which indicates the absence of a close association between HVS-I polymorphisms and T2DM in the Sakha population.

description: To detect less prevalent viruses, such as wild-type polioviruses in sewage from a highly immunized community, a method was developed to efficiently recover viruses and remove PCR inhibitors. The method consisted of initial separation of solids from liquid, followed by solvent extractions, polyethylene glycol precipitations, Sephadex G-200 chromatography, and guanidinium isothiocyanate (GIT) extraction. To elute viruses from the separated solids, 0.5 M threonine (pH 7.5) was as efficient as 3% beef extract but conferred no PCR inhibition. In samples that were concentrated approximately 1,000-fold, 21% of the initially seeded viruses were recovered. When poliovirus type 3 (PV3) Sabin strain at low levels and PV1 LSc strain at high levels were seeded in raw sewage, PV3 was specifically detected in the final sample concentrates at sensitivities of 14 PFU by direct PCR and 0.7 PFU by GIT extraction-PCR. While applying the method to international airplane sewage, which contains high levels of solids as well as commercial sanitizers, 44% (7 of 16) of the samples were found to harbor enteroviruses by both cell culture infectivity and pan-enterovirus PCR analyses. Nucleotide sequencing of the PCR products revealed that multiple enterovirus genotypes were amplified from each final sewage concentrate, whereas the fewer virus genotypes detected by cell culture infectivity were probably the better growing strains. By this method, we demonstrated that air travel may contribute to the intercontinental dissemination of enteric pathogens.

description: The ability to track some structural changes in enhanced green fluorescent protein (EGFP) by observing its fluorescence makes EGFP a convenient object for studying the protein denaturation process and the influence of some factors on denaturation, in particular, the presence of nanoparticles. In this work, we studied the EGFP fluorescence during its deand renaturation processes, as well as the influence of the addition of iron oxide nanoparticles on EGFP fluorescence and these processes. Kinetic measurements of denaturation revealed some details of this process. During renaturation, we managed to achieve a 60% recovery of EGFP fluorescence compared to the native protein. We also demonstrated significant effects of the presence of iron oxide nanoparticles. Iron nanoparticles approximately doubled the denaturation rate and suppressed protein renaturation.
ACUTE MENTAL STRESS AND ARTERIAL STIFFNESS: A COMPARISON BETWEEN HISPANIC AND NONHISPANIC WHITE ADULTS

description: Hispanics face a disproportionate burden of cardiovascular disease (CVD) risk factors, includingmental stress, when compared to non-Hispanic white adults (NHWA). However, the mechanismsunderlying these disparities are not fully understood. This study aimed to investigate the cardiovascularresponse to acute mental stress in Hispanic and NHWA. The randomized crossover design included sixparticipants (all female; four Hispanics) and assessed arterial stiffness using pulse wave velocity as theprimary outcome measure. Hispanics exhibited the greatest increase in PWV during the controlcondition, while NHW individuals showed the greatest increase during the experimental condition. Statestress measures also demonstrated significant differences before and after both test conditions. Thesefindings suggest a counterintuitive cardiovascular response to acute stress in Hispanic adults whencompared to NHWA. This study highlights the need for further research to understand the complexrelationship between mental stress and cardiovascular risk in different populations, in particular,Hispanic adults.

description: Recently it has become clear that many technologies follow a generalized version of Moore's law, i.e. costs tend to drop exponentially, at different rates that depend on the technology. Here we formulate Moore's law as a correlated geometric random walk with drift, and apply it to historical data on 53 technologies. We derive a closed form expression approximating the distribution of forecast errors as a function of time. Based on hind-casting experiments we show that this works well, making it possible to collapse the forecast errors for many different technologies at different time horizons onto the same universal distribution. This is valuable because it allows us to make forecasts for any given technology with a clear understanding of the quality of the forecasts. As a practical demonstration we make distributional forecasts at different time horizons for solar photovoltaic modules, and show how our method can be used to estimate the probability that a given technology will outperform another technology at a given point in the future.
VAFB-1984-23: Archaeological Site Modification in Dunes (M.A. Thesis)
Creators: name: Brown, Roderick S.
Year: 1984

description: This is a preliminary study of the rates at which the wind alters archaeological deposits on the San Antonio Terrace. The study was undertaken as an adjunct to ongoing archaeological work on the terrace in advance of M-X Missile test facilities construction.

The San Antonio Terrace is partially overlain by dunes believed to be less than 2,000 years old (Johnson 1983, Cooper 1967). Johnson labeled the very active dunes near the beach "recent" and the more vegetated dunes farther inland "intermediate" admitting that dunes in these two categories are all relatively recent. These overlie old dunes which are believed to date to the early/mid-Holocene period.
More than 100 archaeological sites have been recorded on the Terrace and 95 of these are situated in the recent and intermediate dunes. Casual observation suggests that many artifacts and much sand have been transported by the almost constant and often forceful northwesterly winds. On windy days, for example, the surface of the dunes is blurred by a layer of saltating grains and the dunes seem to smoke as sand is blown from their crests. At such times, producent archaeological survey and excavation crews wear eye protection against blown sand. Also, during winds, cultural materials (debitage and shell) can be seen flipping along the surface. Given these conditions, archaeological studies in the active regions of the Terrace should be undertaken with the understanding that many Terrace sites have been altered extensively by the wind.

description: The purpose of the study was to study the fronto-occipital organization of cerebral circulation during shortterm mental stress, as well as to study the relationship between the spatial organization of cerebral circulation during mental stress and the effectiveness of behavior control. In this work, attention was paid to potential typological characteristic – fronto-occipital asymmetry of cerebral circulation. Known data suggest a relationship between changes in the spatial distribution of cerebral circulation and the productivity of mental activity and the effectiveness of behavior control. Using the method of rheoencephalography, 40 students (aged 19–23 years) studied the parameters of cerebral circulation during mental stress (GO/NOGO test). The stimulus material was presented on a monitor using the PsychoPy program. The number of errors was estimated. The rheoencephalogram was recorded using the «Reo-Spectrum» device. The spatial organization of pulse blood supply in the basin of the internal carotid and vertebral arteries in the initial state and during mental stress was assessed by the fronto-occipital gradient. With a short-term mental load, students showed an increase in both general and particular fronto-occipital gradients. A negative correlation was established between the increase in the right-diagonal fronto-occipital gradient (reactive control axis) in the first minute of the mental load and the number of errors in the GO/NOGO test. The prospects of using the fronto-occipital organization of cerebral circulation to predict the effectiveness of mental activity are discussed.
Isolation and characterization of an attenuated strain of Pseudomonas aeruginosa AC869, a 3,5-dichlorobenzoate degrader.

description: Pseudomonas aeruginosa AC869, a 3,5-dichlorobenzoate degrader, is a mouse pathogen and has a reported 50% lethal dose (LD50) of 1.05 x 10(7) CFU when given intranasally to C3H/HeJ mice (S.E. George, M.J. Kohan, M.I. Gilmour, M.S. Taylor, H.G. Brooks, J.P. Creason, and L.D. Claxton, Appl. Environ, Microbiol. 59:3585-3591, 1993). AC869 was serotyped as O6 when grown in CD-1 mouse cecal and lung mucus but could not be assigned an O serotype when grown in Luria broth (LB). After growth in mouse cecal mucus, a less virulent mutant, AC869-11, was isolated from AC869 by using bacteriophage E79, which adsorbs to the O side chain of lipopolysaccharide (LPS). AC869-11 produced significantly less O antigen on its LPS than AC869 when grown in mouse lung and cecal mucus. The mutant also produced half the amount of exoenzyme S and 16-fold less extracellular protease than AC869 and was more sensitive than its parent to a number of antibiotics when grown either in LB or in mouse lung mucus. AC869-11 had ninefold higher LD50 than AC869 in CD-1 mice when administered intranasally. AC869-11 was found in the lungs, small intestine, cecum, and large intestine in numbers at least 100-fold below AC869, 3 h after intranasal exposure of mice to a sublethal dose of the two strains. Moreover, AC869-11 induced a decreased pulmonary inflammatory response relative to AC869. In contrast to AC869, AC869-11 did not translocate to the mesenteric lymph nodes, liver, and spleen following a sublethal dose. Despite attenuation, AC869-11 grew as well as AC869 with 3,5-dichlorobenzoate as the sole carbon and energy source. However, although AC869-11 survived in 3,5-dichlorobenzoate-contaminated soil as well as AC869 for 1 week, it failed to survive as well thereafter. These results suggest the possibility that mutations that lead to pulmonary attenuation of P. aeruginosa in mice also lead to weakness in the environment, despite such mutants maintaining the ability to degrade toxic substances under laboratory conditions.

description: Armaments cooperation, theoretically, allows states to develop capabilities that they alone could not. Yet, armaments cooperation’s reality differs from theory: states haggle over conflicting requirements and parochial workshare demands. This thesis evaluates the EU’s Permanent Structured Cooperation (PESCO) and European Defense Fund (EDF) in terms of their organizational design and co-development projects. PESCO’s organizational design displays middling path dependency, and the EDF’s a lesser degree. From this, I devise three expectations for their projects, and test them by building an open-source database of PESCO projects’ progress towards their goals. This thesis corroborates my initial two expectations. First, PESCO and EDF-funded projects comprehensively reflect the EU’s capability development priorities, and more ambitious projects arose in response to EU recommendations. Second, EU-funded PESCO projects demonstrate more progress than those without funding, several of which demonstrate no progress. Contrary to my third expectation, cooperation, in terms of projects managed cooperatively, did not increase.

description: Reducing noises and enhancing signal-to-noise ratios (SNRs) have become critical for designing third-generation gravitational-wave (GW) detectors with a GW strain of less than $10^{-23}$/$\rm \sqrt{Hz}$. In this paper, we propose a potential third-generation GW detector based on autocorrelative weak-value amplification (AWVA) for GW detection with a strain of $h_g =$ $4 \times 10^{-25}$/$\rm \sqrt{Hz}$. In our scheme, a GW event induces a phase difference $Δϕ$ by passing through an 11-bounce delay line, 10-km arm-length, zero-area Sagnac interferometer illuminated with a 1064-nm laser. Subsequently, $Δϕ$ is amplified as the parameter of post-selection by choosing the appropriate pre-selected state and coupling strength in AWVA. In particular, we theoretically investigate the AWVA measurements for GW detection within the frequency band of 200 Hz $\leq$ $f_g$ $\leq$ 800 Hz, considering Gaussian noises with negative-decibel SNRs. The peak response of the AWVA sensitivity $κ(f_g)$ occurs at frequency $f_{g, max}$ = 500 Hz, which falls within the frequency band of interest of the current third-generation GW detectors. Our simulation results indicate that AWVA can demonstrate a measurable sensitivity of $Θ(f_g)$ within the frequency band of interest. Moreover, the robustness of WVA shows promising potential in mitigating the effects of Gaussian noises.

description: We consider the bound state problem for a field theory that contains a Dirac fermion $χ$ that Yukawa couples to a (light) scalar field $ϕ$. We are interested in bound states with a large number $N$ of $χ$ particles. A Fermi gas model is used to numerically determine the dependence of the radius $R$ of these bound states on $N$ and also the dependence of the binding energy on $N$. Since scalar interactions with relativistic $χ$'s are suppressed two regimes emerge. For modest values of $N$ the state is composed of non-relativistic $χ$ particles. In this regime as $N$ increases $R$ decreases. Eventually the core region becomes relativistic and the size of the state starts to increase as $N$ increases. As a result, for fixed Yukawa coupling and $χ$ mass, there is a minimum sized state that occurs roughly at the value of $N$ where the core region first becomes relativistic. We also compute an elastic scattering form factor that can be relevant for direct detection if the dark matter is composed of such $χ$ particles.

VAFB-1985-04: Peacekeeper Program, Cultural Resources Testing and Monitoring, Roads and Utilities, Phase I, Vandenberg AFB, California
Creators: name: URS-Berger
Year: 1985

description: This document is a report that describes cultural resources testing and monitoring as part of the Peacekeeper Rail Garrison program, a program to construct and operate Peacekeeper missile test facilities at VAFB. The project included the installation of utilities and modification of roads. A total of 12 overhead utility lines crossing El Rancho and Umbra roads were undergrounded or modified; one was located in a floodplain and three were within or adjacent to a significant archaeological site (CA-SBA-1060). Cultural resources monitoring activities were required at these four locations. Because prior inspection of the ground surface revealed the existence of cultural remains in the immediate or general vicinity of SBA-1060 and raised the possibility of the presence of subsurface cultural deposits that might require data recovery efforts. Shovel test pits and 1x1 meter test units were excavated in the localities to be disturbed by Component activities during the monitoring phase. A total of 20 STPs and three 1x1-meter Tus were dug at two of the proposed overhead utility line crossings. The Tus were placed in areas where STPs yielded evidence of significant subsurface remains. All units were completed prior to the excavation of boring pits and trenches for the placement of conduits to carry the utility lines under El Rancho Road. Testing demonstrated the existence of important stratified subsurface cultural deposits but did not indicate a need for specific data recovery activities. 

All trenching activities were monitored by a qualified archaeologist and geomorphologist. For the portions of El Rancho Road to be bypassed and for the utility line crossing located in the floodplain , however, advance testing was not feasible or was not considered necessary. Most of the cut-grading for the road bypasses had been completed prior to the beginning of testing, and monitoring activities for the Component and avoidance was no longer possible. Therefore, disturbed areas within the right-of-way only could be surveyed post hoc for signs of exposed cultural deposits that might require stabilization or mitigative activities.

description: Root colonization by Agrobacterium tumefaciens was measured by using tomato and Arabidopsis thaliana roots dipped in a bacterial suspension and planted in soil. Wild-type bacteria showed extensive growth on tomato roots; the number of bacteria increased from 103 bacteria/cm of root length at the time of inoculation to more than 107 bacteria/cm after 10 days. The numbers of cellulose-minus and nonattaching attB, attD, and attR mutant bacteria were less than 1/10,000th the number of wild-type bacteria recovered from tomato roots. On roots of A. thaliana ecotype Landsberg erecta, the numbers of wild-type bacteria increased from about 30 to 8,000 bacteria/cm of root length after 8 days. The numbers of cellulose-minus and nonattaching mutant bacteria were 1/100th to 1/10th the number of wild-type bacteria recovered after 8 days. The attachment of A. tumefaciens to cut A. thaliana roots incubated in 0.4% sucrose and observed with a light microscope was also reduced with cel and att mutants. These results suggest that cellulose synthesis and attachment genes play a role in the ability of the bacteria to colonize roots, as well as in bacterial pathogenesis.

description: In this work, we intend to explore wormhole geometries in the framework of $f(R,L_m)$ gravity. We derive the field equations for the generic $f(R,L_m)$ function by assuming the static and spherically symmetric Morris-Thorne wormhole metric. Then we consider two non-linear $f(R,L_m)$ model, specifically, $f(R,L_m)=\frac{R}{2}+L_m^α$ and $f(R,L_m)=\frac{R}{2}+(1+λR)L_m$, where $α$ and $λ$ are free model parameters. We obtain the wormhole solutions by assuming three cases, namely, a linear barotropic EoS, anisotropic EoS, and isotropic EoS corresponding to model I. We observe that for both barotropic and anisotropic cases, the corresponding wormhole solutions obey the flaring-out condition under asymptotic background, while for the isotropic case, the shape function does not follow the flatness condition. Also, we find that the null energy condition exhibits negative behavior in the vicinity of the throat. Further, we consider two different shape functions to investigate the behavior of model II. We find some constraints on the model parameter for which the violation of the null energy condition exhibits. Finally, we employ the volume integral quantifier to calculate the amount of exotic matter required near the wormhole throat for both models. We conclude that the modification of standard GR can efficiently minimize the use of exotic matter and provide stable traversable wormhole solutions.
