title: Impact Analysis of System and Network Attacks
Creators: name: Biswas, Anupama
Publisher: name: Utah State University
Year: 2008

description: Systems and networks have been under attack from the time the Internet first came into existence. There is always some uncertainty associated with the impact of the new attacks. Compared to the problem of attack detection, analysis of attack impact has received very little attention. Generalize and forecasting the kind of attack that will hit systems in future is not possible. However, it is possible to predict the behavior of a new attack and, thereby, the impact of the attack. This thesis proposes a method for predicting the impact of a new attack on systems and networks as well as the severity of the impact of the new attack. The prediction is based on the assumption that a future attack will be similar to already existing attacks. The severity of the attack depends on a few specific system/network parameters identified in this thesis. The cumulative effect of an attack is a summation of the behavior of these identified parameters during the attack. The suggested method is based on simulating a selected number of existing attacks, collecting the results of the impact of these attacks, and using them along with attack graphs to automatically detect the impact of a new attack. A formula is proposed for calculating the impact severity percentage, which is calculated as a percentage value of the impact of the known attack. This value will help identify critical points that need special care to ensure the readiness of a network or system to withstand an attack.

description: This paper presents a realization for the reliable and fast startup of distributed systems written in Erlang. The traditional startup provided by the Erlang/OTP library is sequential, parallelization usually requires unsafe and ad-hoc solutions. The proposed method calls only for slight modifications in the Erlang/OTP stdlib by applying a system dependency graph. It makes the startup safe, quick, and it is equally easy to use in newly developed and legacy systems.

description: The oral bioavailability and anti-leukaemia activity of Tanshinone IIA (TanIIA) were enhanced by using biotinylated-lipid bilayer coated mesoporous silica nanoparticles (Bio-LB-MSNs) as a vehicle. The in vitro release of TanIIA from TanIIA@MSNs was significantly higher than that of the TanIIA powder (p < .05). The in vitro cellular uptake of TanIIA by Caco-2 was increased by loading drug into the Bio-LB-MSNs more than those of the compared nanovehicles without biotin modification. The apparent in situ permeability coefficient (Papp) of TanIIA@Bio-LB-MSNs showed nearly 2.5-, 1.6- and 1.3-fold improvement compared with the TanIIA powder, TanIIA@MSNs and TanIIA@LB-MSNs. Following oral administration of TanIIA@Bio-LB-MSNs in rats, the area under the plasma concentration–time curves (AUC) of TanIIA was 3.4-, 1.9- and 2.4-fold larger than those in the groups received a pure TanIIA powder, TanIIA@MSNs or TanIIA@LB-MSNs, indicating that drug bioavailability was enhanced by using MSNs as a vehicle, and further improved significantly through biotin modification. The in vitro anti-leukaemia activity of TanIIA was also enhanced after being loaded into nanoparticles and modification, with 50% inhibitive concentration (IC50) of NB4 cells at 6.5 μM for TanIIA@Bio-LB-MSN. In conclusion, Bio-LB-MSNs are a promising vehicle to improve the oral bioavailability and anti-leukaemia activity of the poorly water-soluble drug TanIIA.

description: AbstractThe ambition of the CA3ViAR project is to design an open test case fan that experiences instability mechanisms, which are representative for ultra-high bypass ratio (UHBR) fans of civil aircrafts, and to perform a comprehensive experimental investigation to measure aerodynamic, aeroelastic and aeroacoustic performance in a wide range of operational conditions. Experimental tests will be performed in the Propulsion-Test-Facility (PTF) of the Institute of Jet Propulsion and Turbomachinery (IFAS) of Technische Universität Braunschweig, Germany. The final objective of the project is to provide an open test case for the entire research community, with geometries, numerical and experimental results to establish a new reference for composite UHBR fan design. This will support the development of new methods and tools for the development of safer, lighter and more efficient composite fans for greener UHBR engines. In this work the preliminary design of the low transonic fan (LTF) to be used as test article, whose main requirement is to be operated in a safe and controlled way in conditions of aerodynamic and/or aeroelastic instability during wind tunnel operations, is presented. More in particular, consolidated aerodynamic design, strategy adopted to drive the structural design, flutter analysis taking into account acoustic reflection at the intake, dynamic and stress analyses, as well as aeroacoustic measurement optimization are presented and discussed. The preliminary mechanical design of composite blades and the rotor hub, together with the rotor instrumentation and related studies to embed sensors in the composite blades, are also part of this article, and complemented by manufacturing trials and demonstration tests give the full picture of all the project activities up to the preliminary design review.

description: Although many libraries have acknowledged the fact that digitization will not disappear, development staff remains a rare resource. In order to cope with this challenge, the Berlin State Library has evaluated different repositories with respect to aspects such as their integratability into the Java-based microservice core architecture of the library, their data model flexibility and - most important - their support of parameterizable front-ends to decrease development effort.

Consequently, the Berlin State Library has implemented Fedora 4 in various productive usage scenarios as a repository solution for common library use cases that has proven a perfect fit for existing microservices of the library such as the identity management domain or a SRU gateway.

The presentation will give an overview of the current usage areas of Fedora 4, its positioning in the existent microservice-based infrastructure and the current project business of the Berlin State Library, and outline limitations and caveats of Fedora 4 from a technical and management perspective. The presentation concludes with an outlook on future usage scenarios such as linked data applications.
title: A Novel Authentication And Validation Mechanism For Analyzing Syslogs Forensically
Creators: name: Monteiro, Steena D.S.
Publisher: name: Utah State University
Year: 2008

description: This research proposes a novel technique for authenticating and validating syslogs for forensic analysis. This technique uses a modification of the Needham Schroeder protocol, which uses nonces (numbers used only once) and public keys. Syslogs, which were developed from an event-logging perspective and not from an evidence-sustaining one, are system treasure maps that chart out and pinpoint attacks and attack attempts. Over the past few years, research on securing syslogs has yielded enhanced syslog protocols that focus on tamper prevention and detection. However, many of these protocols, though efficient from a security perspective, are inadequate when forensics comes into play. From a legal perspective, any kind of evidence found at a crime scene needs to be validated. In addition, any digital forensic evidence when presented in court needs to be admissible, authentic, believable, and reliable. Currently, a patchy log on the server side and client side cannot be considered as formal authentication of a wrongdoer. This work presents a method that ties together, authenticates, and validates all the entities involved in the crime scene--the user using the application, the system that is being used, and the application being used on the system by the user. This means that instead of merely transmitting the header and the message, which is the standard syslog protocol format, the syslog entry along with the user fingerprint, application fingerprint, and system fingerprint are transmitted to the logging server. The assignment of digital fingerprints and the addition of a challenge response mechanism to the underlying syslogging mechanism aim to validate generated syslogs forensically.
Dynamical Tides in Rotating Planets and Stars

Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Tidal dissipation may be important for the internal evolution as well as the orbits of short-period massive planets--hot Jupiters. We revisit a mechanism proposed by Ogilvie and Lin for tidal forcing of inertial waves, which are short-wavelength, low-frequency disturbances restored primarily by Coriolis rather than buoyancy forces. This mechanism is of particular interest for hot Jupiters because it relies upon a rocky core, and because these bodies are otherwise largely convective. Compared to waves excited at the base of the stratified, externally heated atmosphere, waves excited at the core are more likely to deposit heat in the convective region and thereby affect the planetary radius. However, Ogilvie and Lin's results were numerical, and the manner of the wave excitation was not clear. Using WKB methods, we demonstrate the production of short waves by scattering of the equilibrium tide off the core at critical latitudes. The tidal dissipation rate associated with these waves scales as the fifth power of the core radius, and the implied tidal $Q$ is of order ten million for nominal values of the planet's mass, radius, orbital period, and core size. We comment upon an alternative proposal by Wu for exciting inertial waves in an unstratified fluid body by means of compressibility rather than a core. We also find that even a core of rock is unlikely to be rigid. But Ogilvie and Lin's mechanism should still operate if the core is substantially denser than its immediate surroundings.

We represent $\operatorname{s}_λ(y_1^{[\varkappa_1]},\ldots,y_n^{[\varkappa_n]})$ as a quotient whose the denominator is the determinant of the confluent Vandermonde matrix, and the numerator is the determinant of some generalized confluent Vandermonde matrix. We give three algebraic proofs of this formula.

description: The work is focused on the design of drugs that prevent and treat diabetes and its complications. A novel class of stilbene derivatives were prepared by coupling NO donors of alkyl nitrate and were fully characterised by NMR and other techniques. These compounds were tested in vitro activity, including α-glucosidase inhibitory activity, aldose reductase (AR) inhibitory activity and advanced glycation end products (AGEs) formation inhibitory activity. A class of modified compounds could play a significant effect for treatment of diabetic complications. Target compounds 3e and 7c offered a potential drug design concept for the development of therapeutic or preventive agents for diabetes and its complications.

We find that if a strong IR field is applied, the attosecond pulses will appear to have lower-than-actual chirp rates. We also observe the onset of the streaking regime in the breakdown of the weak-field RABITT conditions. We perform a Fourier-analysis of harmonic and sideband continuum states and show that the mutual phase relation of the harmonics can be extracted from higher Fourier components.

Teachers' narratives of resisting deprofessionalization
Creators: name: Mendonça Dos Santos, Rodrigo
Publisher: name: University of British Columbia
Year: 2024

description: The development of neoliberal educational reforms has repeatedly shown its target to be teachers and teaching (Ball, 2000, 2003; Ball & Olmedo, 2013; Biesta, 2017; Buchanan, 2015). Educational accountability in neoliberal terms has turned into a managerial tool of surveillance (Biesta, 2017) that deprofessionalized and then reprofessionalized teachers into new ethics where performance substitutes professional judgment (Ball 2003, p. 218). Giroux (2018) argued that it is urgent for educators and researchers to develop a discourse of educated hope against the neoliberal imposition in education. A language of critique and possibility that exposes and challenges the unchallenged neoliberal narrative of our time (Giroux, 2019). In this study, I used narrative inquiry to address the following research questions: (i) how do teachers narrate the deprofessionalization of teaching imposed by accountability mandates / neoliberalization processes through their everyday practices? (ii) how does resistance manifest in teachers’ narratives of themselves as professionals? (iii) how can/do stories function as a language of resistance that fosters further acts of resistance? Findings show that teachers reclaim their authority using different types of tactics (de Certeau, 1984) and insurgent pedagogies. This study identified tactics of resistance such as: (i) the Madagascar Penguin tactic; (ii) the sabotage of public documents; (iii) a dog and pony show; and (iv) the reappropriation of neoliberal places. Teachers go through deprofessionalization processes that include: (i) a psychological war about how to behave; (ii) the commodification of teacher practices; (iii) the bureaucratization of teaching; and (iv) the precarization of teachers’ work. The findings also indicate that stories connected to grand narratives about teaching can serve as political resources for teachers to reimagine possibilities to engage in critical pedagogy practices under situations of oppression.

title: Reported Mental Health Issues and Marital Quality: A Statewide Survey
Creators: name: Smart, Joseph Ruben
Publisher: name: Utah State University
Year: 2008

description: This study included a representative random sample of 886 married individuals in Utah. This sample was surveyed to discover the relationship between demographic variables, reported mental health issues, and marital quality. In addition, this study sought to discover models, using demographic variables and reported mental health issues, to predict for separate dimensions of marital quality. This survey was a replication of a study completed primarily in Oklahoma, with the addition of questions about the participants' mental health. Spearman's rho, Pearson's R, and multiple regression were used to analyze the data. The results of the study show that: religious beliefs had a statistically significant relationship with commitment/satisfaction, with stability, and negative interactions. Religious activity had a statistically significant relationship with commitment/satisfaction, and negative interactions. The duration of marriage had a statistically significant relationship with stability, negative interactions, and age at time of current marriage. The models found for predicting the separate dimensions of marital quality including commitment and satisfaction, stability, and negative interactions were all robust. Implications and recommendations are discussed.
title: Sources and Source Processes of Organic Nitrogen Aerosols in the Atmosphere
Creators: name: Erupe, Mark E.
Publisher: name: Utah State University
Year: 2008

description: The research in this dissertation explored the sources and chemistry of organic nitrogen aerosols in the atmosphere. Two approaches were employed: field measurements and laboratory experiments. In order to characterize atmospheric aerosol, two ambient studies were conducted in Cache Valley in Northern Utah during strong winter inversions of 2004 and 2005. The economy of this region is heavily dependent on agriculture. There is also a fast growing urban population. Urban and agricultural emissions, aided by the valley geography and meteorology, led to high concentrations of fine particles that often exceeded the national ambient air quality standards. Aerosol composition was dominated by ammonium nitrate and organic species. Mass spectra from an aerosol mass spectrometer revealed that the organic ion peaks were consistent with reduced organic nitrogen compounds, typically associated with animal husbandry practices. Although no direct source characterization studies have been undertaken in Cache Valley with an aerosol mass spectrometer, spectra from a study at a swine facility in Ames, Iowa, did not show any evidence of reduced organic nitrogen species. This, combined with temporal and diurnal characteristics of organic aerosol peaks, was a pointer that the organic nitrogen species in Cache Valley likely formed from secondary chemistry. Application of multivariate statistical analyses to the organic aerosol spectra further supported this hypothesis. To quantify organic nitrogen signals observed in ambient studies as well as understand formation chemistry, three categories of laboratory experiments were performed. These were calibration experiments, smog chamber studies, and an analytical method development. Laboratory calibration experiments using standard calibrants indicated that quantifying the signals from organic nitrogen species was dependent on whether they formed through acid-base chemistry or via secondary organic aerosol pathway. Results from smog chamber reactions of amines with ozone, nitrogen oxides, nitrate radical, and nitric acid showed that the secondary organic aerosol pathway was more plausible than acid-base chemistry, thus making the contribution of the organic nitrogen species to the total aerosol mass in Cache Valley significant. Gas phase and aerosol products formed from the smog chamber reactions were identified and used to devise reaction mechanisms. Finally, an ion chromatographic method for detecting and quantifying some key organic nitrogen species in aerosol was developed and tested.

Creators: name: Johnson, Eric W
Publisher: name: Utah State University
Year: 2008

description: This qualitative study investigates how leadership is embodied within the role of seminary principals in released-time seminaries for The Church of Jesus Christ of Latter-day Saints. This study utilized a grounded theory approach and constant comparative analysis while triangulating the data obtained from personal interviews, participant observations, and analysis of documents. The primary sources of data came from the personal experiences and perspectives of four principals, eight teachers, and one area administrator that are analyzed through biographical interviews. Analyses of the data were completed to determine common themes of leadership that were embodied by principals in released-time seminaries for The Church of Jesus Christ of Latter-day Saints. Results included the importance of: (a) principals as trainers, (b) a lack of training for seminary principals, (c) principals as a reflection of higher administration, (d) principal's influence on faculty unity, (e) principal's focus on assisting the struggling student, (f) ensuring faculty professionalism, (g) personal satisfaction and growth, and (h) managerial organization. Recommendations from this study help provide a framework of leadership practices for current and future seminary principals, as well as those who oversee seminary principals within the Church Educational System.

description: Family participation in residential treatment for disturbed adolescents has increased over time. A general sense of this movement is that this is beneficial. However, there are no common discriptions of family involvement in residential treatment in the literature. In order to be able to better understand which components of famiy involvement are most beneficial, we need to first understand how residential treatment centers define and describe famiy involvement. This study compiled data from interviews with nine participants, one each from administration, therapy staff, and direct care staff level of three northern Utah RTCs that claimed family involvement in youth treatment at their centers.
title: Longitudinal and Reciprocal Effects of Ethnic Identity and Experiences of Discrimination on Psychosocial Adjustment of Navajo (Diné) Adolescents
Creators: name: Jones, Matthew D
Publisher: name: Utah State University
Year: 2008

description: This study examined the relationships among ethnic identity, cultural identity, experiences of discrimination, their interactions, and their effects on various psychosocial outcomes (self-esteem, depression, sense of school membership, social functioning, substance abuse, substance related problems, delinquent behaviors, and grade point average [GPA]). Data were collected twice over a 2-year period. Change across time was observed in male adolescents' experiences of discrimination. Affirmation and belonging to Navajo culture was the strongest protective predictor at Time 1, but at Time 2 less consistent patterns of association emerged. Also at Time 2, experiences of discrimination emerged as a powerful negative predictor of psychosocial functioning for boys only. Finally, there were very few longitudinal links between ethnic identity, discrimination experiences, and psychosocial functioning, suggesting that more complex and sophisticated analyses and designs may be necessary to more clearly delineate the longitudinal implications of ethnic identity development.

description: In the following paper we present an internal shocks model, iShocks, for simulating a variety of relativistic jet scenarios; these scenarios can range from a single ejection event to an almost continuous jet, and are highly user configurable. Although the primary focus in the following paper is black hole X-ray binary jets, the model is scale and source independent and could be used for supermassive black holes in active galactic nuclei or other flows such as jets from neutron stars. Discrete packets of plasma (or `shells') are used to simulate the jet volume. A two-shell collision gives rise to an internal shock, which acts as an electron re-energization mechanism. Using a pseudo-random distribution of the shell properties, the results show how for the first time it is possible to reproduce a flat/inverted spectrum (associated with compact radio jets) in a conical jet whilst taking the adiabatic energy losses into account. Previous models have shown that electron re-acceleration is essential in order to obtain a flat spectrum from an adiabatic conical jet: multiple internal shocks prove to be efficient in providing this re-energization. We also show how the high frequency turnover/break in the spectrum is correlated with the jet power, $ν_b \propto L_{\textrm W}^{\sim 0.6}$, and the flat-spectrum synchrotron flux is correlated with the total jet power, $F_ν\propto L_{\textrm W}^{\sim 1.4}$. Both the correlations are in agreement with previous analytical predictions.

description: We study the renormalization group flow of the Lagrangian for statistical and quantum systems by representing their path integral in terms of a tensor network. Using a tensor-entanglement-filtering renormalization (TEFR) approach that removes local entanglement and coarse grain the lattice, we show that the resulting renormalization flow of the tensors in the tensor network has a nice fixed-point structure. The isolated fixed-point tensors $T_{inv}$ plus the symmetry group $G_{sym}$ of the tensors (i.e. the symmetry group of the Lagrangian) characterize various phases of the system. Such a characterization can describe both the symmetry breaking phases and topological phases, as illustrated by 2D statistical Ising model, 2D statistical loop gas model, and 1+1D quantum spin-1/2 and spin-1 models. In particular, using such a $(G_{sym}, T_{inv}) $ characterization, we show that the Haldane phase for a spin-1 chain is a phase protected by the time-reversal, parity, and translation symmetries. Thus the Haldane phase is a symmetry protected topological phase. The $(G_{sym}, T_{inv})$ characterization is more general than the characterizations based on the boundary spins and string order parameters. The tensor renormalization approach also allows us to study continuous phase transitions between symmetry breaking phases and/or topological phases. The scaling dimensions and the central charges for the critical points that describe those continuous phase transitions can be calculated from the fixed-point tensors at those critical points.

description: This Standard Operating Procedure (SOP) outlines the methodology for computing the shortest distance from the centroid of various cell types (e.g., immune cells) to the nearest vasculature, commonly referred to as endothelial or blood vessel cells. This computation supports the creation of a VCCF (Vasculature Common Coordinate Framework) system. The SOP focuses primarily on the process to transform raw data into formats suitable for computation, running the VCCF code, and deploying resulting visualizations. To exemplify the process, the SOP uses skin Cell DIVE data from Ghose et al. 2023 but the process is organ and assay type agnostic.
The primary audience for this SOP includes research scientists, data analysts, and technicians involved in tissue imaging and analysis. Familiarity with Python programming and cell biology basics is assumed. The SOP does not cover advanced statistical analyses or organ-specific interpretations of the VCCF data and visualizations.

The "two-photon" approximation is formulated which is limited by the one-photon and two-photon transitions including cascades transitions with two-photon links. This may be helpful for the strict description of the recombination process in hydrogen atom and, in principle, for the history of the hydrogen recombination in the early Universe.

title: Weight and Body Composition Change During the First Year of College: A Study of Traditional Residence Hall Freshmen
Creators: name: Christensen, Stephanie V
Publisher: name: Utah State University
Year: 2008

description: Overweight and obesity trends are on the rise, and young people are no exception. The popular phrase "Freshman 15" suggests that freshmen in college tend to gain weight faster than other populations. There is a growing body of literature that supports evidence of increased weight gain during the transition from high school to college. This study sought to examine not only weight changes among freshmen, but body composition, body mass index (BMI), and waist circumference (WC) changes as well. Body composition was measured using air displacement plethysmography (Bod Pod®). This study examined changes in both males (n = 45) and females (n = 43), as well as a subsample of Division I collegiate athletes (n = 19). The present study evaluated changes that occurred among a final group of 107 participants. Measurements were taken at the beginning of the semester in September, again in December, and at the end of the school year in April. Self-report questionnaires based on nutritional and physical activity were also evaluated. Significant increases in weight (2.1 ± 2.6 kg), BMI (0.69 ± 0.87 kg/m2), and WC (1.7 ± 2.7 cm) did occur during the freshman year. However, the change in body composition was not significant (p > 0.05). There was no relationship between the nutrition responses and the body composition changes that occurred with the exception of a weak relationship between change in "total caloric consumption during your freshman year" and change in body mass (r = 0.25, p < 0.05), change in BMI (r = 0.24, p < 0.05), and change in %BF (r = 0.20, p < 0.05). Regarding exercise, "total time spent doing physical activity during your freshman year" was inversely correlated to change in %BF (r = 0.27, p < 0.01). Finally, differences between non-athletes and athletes were not statistically significant (p > 0.05). These findings indicate that there are significant physical changes that occur during the freshman year of college. These changes may be a result of changes in environment, caloric consumption, and decreased physical activity. However, results did not indicate that these changes include a significant increase in percent body fat.

description: The study examined how hedge accounting moderates the relationship between financial risk management and the performance of insurance companies. The structural equation modelling approach was adopted using SMART PLS 3.3.3. The results revealed that financial risk management has a significant effect on performance while hedge accounting has no significant effect. The results further revealed that hedge accounting does not moderate the nexus of financial risk management and performance. The study concludes that insurance businesses should effectively manage their risk because risk management has been shown to have a favourable impact on financial success. The study also suggests that insurance company executives evaluate their risk management techniques on a regular basis to see if they are still applicable in the face of a rapidly changing operating environment. The study further suggests that insurance company executives review their risks' exposure to edit risk, bankruptcy risk, and interest rate sensitivity on a regular basis. Insurance businesses must improve their capital adequacy and operational efficiency in proportion to their size. Finally, the report suggests that insurance company executive’s implement risk management frameworks such as enterprise risk management that follow international best practices. As a result, insurance businesses will be able to meet international requirements and so become more international rivalry.

description: Transferring information from observations of a dynamical system to estimate the fixed parameters and unobserved states of a system model can be formulated as the evaluation of a discrete time path integral in model state space. The observations serve as a guiding potential working with the dynamical rules of the model to direct system orbits in state space. The path integral representation permits direct numerical evaluation of the conditional mean path through the state space as well as conditional moments about this mean. Using a Monte Carlo method for selecting paths through state space we show how these moments can be evaluated and demonstrate in an interesting model system the explicit influence of the role of transfer of information from the observations. We address the question of how many observations are required to estimate the unobserved state variables, and we examine the assumptions of Gaussianity of the underlying conditional probability.

title: Hydrogen Production By Anaerobic Fermentation Using Agricultural and Food Processing Wastes Utilizing a Two-Stage Digestion System
Creators: name: Thompson, Reese S
Publisher: name: Utah State University
Year: 2008

description: Hydrogen production by means of anaerobic fermentation was researched utilizing three different substrates. Synthetic wastewater, dairy manure, and cheese whey were combined together at different concentrations under batch anaerobic conditions to determine the optimal hydrogen producing potential and waste treatment of each. Cheese whey at a concentration of 55% was combined with dairy manure at a concentration of 45% to produce 1.53 liters of hydrogen per liter of substrate. These results are significant because the control, synthetic wastewater, which was a glucose-based substrate, produced less hydrogen, 1.34 liters per liter of substrate, than the mixture of cheese whey and dairy manure. These findings indicate that cheese whey and dairy manure, which are of little value, have potential to produce clean combusting hydrogen fuel. The effluent from the anaerobic hydrogen fermentations was then placed into a second continuous-fed reactor as part of a two-phase anaerobic digestion system. This system was designed to produce hydrogen and methane for a mixture of approximately 10% hydrogen. The two-stage process also further treated the synthetic wastewater, dairy manure, and cheese whey. The two-phase anaerobic methanogenic reactor was shown to produce more methane in the second phase (56 L IBR anaerobic digester), 1.36 mL per minute per liter substrate, as compared to the single-phase anaerobic reactor (56 L IBR), which produced 1.22 mL per minute per liter substrate. In general, this research has suggested that agricultural and food processing wastes provide the needed nutrients for hydrogen production and that a two-phase anaerobic digestion system is ideally set up to produce hydrogen-methane mixtures while treating wastes for discharge into the environment.
Radiative corrections to the $R$ and $R^2$ invariants from torsion fluctuations on maximally symmetric spaces

description: We derive the runnings of the $R$ and $R^2$ operators that stem from integrating out quantum torsion fluctuations on a maximally symmetric Euclidean background, while treating the metric as a classical field. Our analysis is performed in a manifestly covariant way, exploiting both the recently-introduced spin-parity decomposition of torsion perturbations and the heat kernel technique. The Lagrangian we start with is the most general one for 1-loop computations on maximally symmetric backgrounds involving kinetic terms and couplings to the scalar curvature that is compatible with a gauge-like symmetry for the torsion. The latter removes the twice-longitudinal vector mode from the spectrum, and it yields operators of maximum rank four. We also examine the conditions required to avoid ghost instabilities and ensure the validity of our assumption to neglect metric quantum fluctuations, demonstrating the compatibility between these two assumptions. Then, we use our findings in the context of Starobinsky's inflation to calculate the contributions from the torsion tensor to the $β$-function of the $R^2$ term. While this result is quantitatively reliable only at the $0$-th order in the slow-roll parameters or during the very early stages of inflation -- due to the background choice -- it qualitatively illustrates how to incorporate quantum effects of torsion in the path integral formalism.

description: We participated in three of the protein-protein interaction subtasks of the Second BioCreative Challenge: classification of abstracts relevant for protein-protein interaction (IAS), discovery of protein pairs (IPS) and text passages characterizing protein interaction (ISS) in full text documents. We approached the abstract classification task with a novel, lightweight linear model inspired by spam-detection techniques, as well as an uncertainty-based integration scheme. We also used a Support Vector Machine and the Singular Value Decomposition on the same features for comparison purposes. Our approach to the full text subtasks (protein pair and passage identification) includes a feature expansion method based on word-proximity networks. Our approach to the abstract classification task (IAS) was among the top submissions for this task in terms of the measures of performance used in the challenge evaluation (accuracy, F-score and AUC). We also report on a web-tool we produced using our approach: the Protein Interaction Abstract Relevance Evaluator (PIARE). Our approach to the full text tasks resulted in one of the highest recall rates as well as mean reciprocal rank of correct passages. Our approach to abstract classification shows that a simple linear model, using relatively few features, is capable of generalizing and uncovering the conceptual nature of protein-protein interaction from the bibliome. Since the novel approach is based on a very lightweight linear model, it can be easily ported and applied to similar problems. In full text problems, the expansion of word features with word-proximity networks is shown to be useful, though the need for some improvements is discussed.
