title: Impact of Fish Oil on Intestinal Permeability, Inflammation, and Performance in Swine
Creators: name: Alberto, Anthony Fernando
Publisher: name: Utah State University
Year: 2021

description: Our research examined the effects of fish oil supplementation on intestinal permeability, systemic inflammation and performance in piglets. An lipopolysaccharide (LPS) challenge was done to stimulate the synthesis and release of the cytokines, in an effort to mimic the immune response that piglets would have when facing stress or pathogen challenge. Fish oil increased feed intake but did not affect growth when compared to control. Total fatty acid digestibility increased by 6% when fish oil was included in the diet. Also, we observed a 16% increase on 16-carbon fatty acids digestibility. Fish oil did not affect the plasma D-xylose concentration used to analyze in-vivo intestinal permeability.The plasma concentration of the pro-inflammatory cytokine TNF-α was not affected by fish oil before the LPS challenge. Immune stimulation by the LPS challenge results in the production of pro-inflammatory cytokines, which can suppress growth. After the LPS challenge, fish oil decreased PGE2 and tended to decrease IL-6 concentration in blood samples, while TNF-α increased. A Ussing chamber was used to monitor intestinal permeability ex-vivo. Fish oil tended to enhance the intestinal barrier function by decreasing the FITC flux reflecting a fortified intestinal barrier function. Our results suggest that supplementing an omega-3 PUFA source may modulate the immune response and promote intestinal integrity when the animals are facing an immune challenge. The protective effects of fish oil on the intestine may be closely related to preventing systemic inflammation by decreasing intestinal permeability.

description: We present the results of the high-resolution spectroscopic observations of the neglected binary system HD\,194495 (B3\,IV-V+B4\,V). A combined analysis of three different photometric data set ($Tycho$ B$_T$ and V$_T$ photometry, H$_p$-band data of $Hipparcos$ and $V-$band data of ASAS3 photometry) and radial velocities indicates that the system has an orbital period of 4.90494 $\pm$ 0.00005 days and an inclination of 69$\pm$1 degrees. This solution yields masses and radii of $M_{\rm 1}$ = 7.57$\pm$0.08 $M_{\odot}$ and $R_{\rm 1}$ = 5.82$\pm$0.03 $R_{\odot}$ for the primary and $M_{\rm 2}$ = 5.46$\pm$0.09 $M_{\odot}$ and $R_{\rm 2}$ = 3.14$\pm$0.08 $R_{\odot}$ for the secondary. Based on the position of the two stars plotted on a theoretical H-R diagram, we find that the age of the system is $\gtrsim$ 28 Myr, according to stellar evolutionary models. The spectroscopic and photometric results are in agreement with those obtained using theoretical predictions.

Evidence is found that the star is in a multiple stellar system with two other companions. The dynamical complexity of the system indicates that it may have experienced secular interactions such as the Kozai mechanism or a formation that differs from the ``classical" disc-migration theory.

description: The channeling of the ion recoiling after a collision with a WIMP changes the ionization signal in direct detection experiments, producing a larger signal than otherwise expected. We give estimates of the fraction of channeled recoiling ions in NaI (Tl), Si and Ge crystals using analytic models produced since the 1960's and 70's to describe channeling and blocking effects. We find that the channeling fraction of recoiling lattice nuclei is smaller than that of ions that are injected into the crystal and that it is strongly temperature dependent.

"Without tearing the web apart": Pierre, The Marble Faun, and aesthetics of network
Creators: name: Lee, Catherine Ji Won
Publisher: name: University of British Columbia
Year: 2016

description: In this thesis, I suggest Actor-Network-Theory as a methodology for aesthetic analysis that is faithful to the phenomenology of the aesthetic. With ANT, I examine the aesthetic landscapes of Herman Melville's Pierre; or the Ambiguities and Nathaniel Hawthorne's The Marble Faun: or, the Romance of Monte Beni, two works of American literature with notoriously peculiar aesthetic, and discover in the process that new conclusions about the texts can be drawn when we focus less on aesthetic judgments and pay more attention to the particulars of each text. What I find in the two texts are networks, emerging from connections between and among human and nonhuman actors, in which subjects are thoroughly enmeshed. In Pierre, the implication of the involvement in networks is the loss of subjective autonomy; in The Marble Faun, the consequence is the evaporation of the illusion that we can know the world.

We focus on the coarsening dynamics subsequent to a quench from the massless quark phase to the massive quark phase. The morphology of the ordering system is characterized by the scaling of the order-parameter correlation function. The domain growth process obeys the Allen-Cahn growth law, $L(t)\sim t^{1/2}$. We also study the growth of bubbles of the stable massive phase from the metastable massless phase.

PAC learnability of a concept class under non-atomic measures: a problem by Vidyasagar

description: In response to a 1997 problem of M. Vidyasagar, we state a necessary and sufficient condition for distribution-free PAC learnability of a concept class $\mathscr C$ under the family of all non-atomic (diffuse) measures on the domain $Ω$. Clearly, finiteness of the classical Vapnik-Chervonenkis dimension of $\mathscr C$ is a sufficient, but no longer necessary, condition. Besides, learnability of $\mathscr C$ under non-atomic measures does not imply the uniform Glivenko-Cantelli property with regard to non-atomic measures. Our learnability criterion is stated in terms of a combinatorial parameter $\VC({\mathscr C}\,{\mathrm{mod}}\,ω_1)$ which we call the VC dimension of $\mathscr C$ modulo countable sets. The new parameter is obtained by ``thickening up'' single points in the definition of VC dimension to uncountable ``clusters''. Equivalently, $\VC(\mathscr C\moddω_1)\leq d$ if and only if every countable subclass of $\mathscr C$ has VC dimension $\leq d$ outside a countable subset of $Ω$. The new parameter can be also expressed as the classical VC dimension of $\mathscr C$ calculated on a suitable subset of a compactification of $Ω$. We do not make any measurability assumptions on $\mathscr C$, assuming instead the validity of Martin's Axiom (MA).

Hybrid optical pumping of optically dense alkali-metal vapor without quenching gas
Creators: name: Romalis, M. V.
Publisher: name: arXiv
Year: 2010
Subjects: subject: Atomic Physics (physics.atom-ph)
subject: FOS: Physical sciences

description: Optical pumping of an optically thick atomic vapor typically requires a quenching buffer gas, such as N$_{2}$, to prevent radiation trapping of unpolarized photons which would depolarize the atoms. We show that optical pumping of a trace contamination of Rb present in K metal results in a 4.5 times higher polarization of K than direct optical pumping of K in the absence of N$_{2}$. Such spin-exchange polarization transfer from optically-thin species is useful in a variety of areas, including spin-polarized nuclear scattering targets and electron beams, quantum-non-demolition spin measurements, and ultra-sensitive magnetometry.

Characterizing ADAM28 function in trophoblast differentiation
Creators: name: De Luca, Lauren Celeste
Publisher: name: University of British Columbia
Year: 2016

description: Human placental development is a complex process dependent on continuous cross talk between fetal and maternal uterine compartments. Trophoblasts, placental cells of fetal epithelial lineage, invade the maternal uterine lining, forming the maternal-fetal interface. This interface is vital for controlling nutrient, gas, and waste exchange between maternal and fetal circulatory systems. The differentiation of progenitor trophoblasts into highly-specific cell subsets important for placental function is a highly-regulated developmental process. Trophoblast differentiation into invasive subtypes is essential for enhancing optimal uterine artery physiology, maternal-fetal nutrient exchange, and immunotolerance in pregnancy. Trophoblast invasion is controlled by cell-cell and cell-matrix interactions, as well as through production of various growth factors, cytokines, and hormones. Insufficient trophoblast invasion results in insufficient arterial remodeling that underlies cellular events responsible for the development of pregnancy disorders such as preeclampsia and fetal growth restriction. A Disintegrin and Metalloproteinase 28 (ADAM28) is a multi-functional protein belonging to the metzincin superfamily of metalloproteinases. ADAM28 exists as two alternative splice variants: a full-length transmembrane form (ADAM28-L) and a truncated secreted variant (ADAM28-S). Recently, ADAM28 has been shown to be differentially expressed in two distinct trophoblast subtypes ex vivo; however despite this knowledge, little is known about the role of ADAM28 in placental development or trophoblast biology. My research has demonstrated that both ADAM28 isoforms are highly expressed in invasive trophoblasts of distal regions in placental columns. Utilizing a loss-of-function strategy, I demonstrate that ADAM28 promotes trophoblast column outgrowth, and directs trophoblast cell migration and survival. Collectively, these findings describe a novel role for ADAM28 in regulating the differentiation of progenitor trophoblasts into extravillous trophoblast subsets and highlight ADAM28 as a key protease in human placental development.
title: Diet and Nutritional Concerns of Hispanic Americans
Creators: name: Rawlinson, Valerie
Publisher: name: Utah State University

description: Hispanic Americans are the second largest ethnic minority group in the United States today, at 12.5% of the total U.S. population. They face considerable nutrition-related challenges, of which dietitians and other nutrition professionals who serve this population need to be aware. Their diet goes through drastic, rapid changes soon after immigration to the United States, many of which have a strong negative impact on their health, putting them at greater risk for obesity and chronic diseases than the general population. In addition to diet and disease, Hispanic Americans face other issues that hinder their ability to benefit from nutritional counseling, such as lack of food safety knowledge, language barriers, and attachment to traditional alternative remedies. Community based, culturally tailored interventions are producing impressive results in helping Hispanics achieve improved nutritional status. The goal of this paper is to present a general overview of the basic issues that are presented in the last five years of research on Hispanics and nutrition.
title: The Association Between Sleep and Body Mass Index (BMI) in College Freshmen at Utah State University
Creators: name: Sullivan, Mary-Marie Austin
Publisher: name: Utah State University
Year: 2007

description: Background: Obesity has become a major health problem with increasing prevalence in the United States. Cases of obesity have increased at alarming rates and have almost doubled over the past 40 years. During this same period of time, sleep duration for all age groups has significantly declined. Because sleep duration is a potential mediator of energy metabolism and body weight, it is an important aspect of health. An association between short habitual sleep time and increased body mass index (BMI) has been reported in large population studies for US young adults. Freshmen college students may encounter many environmental and emotional changes that may lead to sleep deprivation. Perhaps, it is sleep deficit within college freshmen that contributes to the phenomena of “The Freshmen 15”, which suggests that college freshmen often gain weight during their first year of college.
Objectives: The purpose of this study was to determine the relationship between sleep duration and body mass index (BMI) in a subset of college freshmen at Utah State University during their first academic year.
Methods: The “USU Freshmen Health Study” (PI: Heidi Wengreen, PhD, RD) provided all the data needed to study the relationship between sleep duration and BMI. As such, three data collections during the academic year of 2005-2006 were conducted for 186 college freshmen students, ages 18-19, at Utah State University. The data collections occurred during the beginning of fall semester, the end of fall semester, and the end of spring semester. Participants were asked to report an estimate of their average sleep duration for weekdays and weekends during each data collection period. BMI (kg/m2) was calculated based on measured weight and heights, which were measured during each of the three data collection periods.
Results: No significant changes in average sleep or average BMI were seen between each data collection for this population. Therefore, the overall mean duration of sleep was 7.33 hours per night while the mean BMI was 23.48.At baseline, shorter sleep duration was correlated with higher BMI among men but not women (p=.021 vs. p=.738). Average sleep duration was lowest in the first data collection compared to the second and third data collections (7.05 hours (SD=1.10), 7.42 hours (SD=1.12), 7.51 hours (SD=1.10), respectively), although these differences were not statistically significant.
Conclusion: This population of college freshmen students are not getting the recommended 8.5-9.25 hours of sleep, as outlined by the National Sleep Foundation for adolescents and teens (12-19 years of age). Sleep deprivation may be a potential risk factor for higher BMI at least among college freshmen males.Observed differences between men and women for sleep duration and its affect on BMI, may be the result of gender differences in physiology and hormonal regulation.

description: The rate of the carbon-nitrogen-oxygen (CNO) cycle of hydrogen burning is controlled by the 14N(p,gamma)15O reaction. The reaction proceeds by capture to the ground states and several excited states in O-15. In order to obtain a reliable extrapolation of the excitation curve to astrophysical energy, fits in the R-matrix framework are needed. In an energy range that sensitively tests such fits, new cross section data are reported here for the four major transitions in the 14N(p,gamma)15O reaction. The experiment has been performed at the Laboratory for Underground Nuclear Astrophysics (LUNA) 400 kV accelerator placed deep underground in the Gran Sasso facility in Italy. Using a composite germanium detector, summing corrections have been considerably reduced with respect to previous studies. The cross sections for capture to the ground state and to the 5181, 6172, and 6792 keV excited states in O-15 have been determined at 359, 380, and 399 keV beam energy. In addition, the branching ratios for the decay of the 278 keV resonance have been remeasured.

title: Exploring Gifted Education Programs, Services, and Practices in Islamic Schools in the United States
Creators: name: Al-Lawati, Fatma Anwer Khamis
Publisher: name: Utah State University
Year: 2003

description: This study explored the state of gifted education in Islamic schools in the United States, focusing on school organization and elementary school teachers' practices in planning and implementing instructional and curricular experiences for gifted students and average students. The study utilized mixed methods, combining quantitative and qualitative data. Surveys addressed teacher practices and obtained information about resources available for gifted students in Islamic schools. A focus group method was employed to understand better teachers' practices with gifted students.
The study involved 32 principals and 157 teachers. Five schools participated in the focus group discussions. Descriptive statistics were used to report the presence of identification and program services for gifted students and of classroom instructional and curricular practices. Mean differences, standard deviations, effect sizes, and p values of t tests comparing teachers' practices with gifted and average students were calculated. Data from focus groups and principal interviews were analyzed using the qualitative methods of memoranda writing and matrix analyses across and within schools and categories.
Findings suggest that Islamic schools in the United States have limited programs for gifted students. A majority of teachers in Islamic schools differentiate little between gifted and average students in instructional strategies. When differentiation occurs, it is very basic. Further, several factors contribute to the general lack of gifted education in the Islamic schools, including conceptual, resource, and organizational issues. Teachers at Islamic schools present Islamic values to all students without differentiation between gifted and average students. Although all the Islamic schools were found to value the teachings of Islamic principles to their students, most Islamic school curricula are not found to integrate these values within content areas.
This study suggests that Islamic schools should articulate a clear philosophical, theoretical, and practical concept in regard to gifted education, which should be supported by professional development. Further, Islamic schools' philosophies should articulate a clear method for curriculum integration that merges secular and religious education.
The Eddington factor as the key to understand the winds of the most massive stars. Evidence for a Gamma-dependence of Wolf-Rayet type mass loss

description: The most massive stars are thought to be hydrogen-rich Wolf-Rayet stars of late spectral subtype (WNh stars). In previous theoretical studies the enhanced mass loss of these stars has been attributed to their proximity to the Eddington limit. Here we investigate observed trends in the mass-loss properties of such young, very massive stars. We derive theoretical mass-luminosity relations for very massive stars, based on a large grid of stellar structure models. Using these relations, we estimate Eddington factors for a sample of stars, under different assumptions of their evolutionary status. We evaluate the resulting mass-loss relations, and compare them with theoretical predictions. We find observational evidence that the mass loss in the WR regime is dominated by the Eddington parameter Gamma_e, which has important consequences for the way we understand Wolf-Rayet stars and their mass loss. In addition, we derive wind masses that support the picture that the WNh stars in young stellar clusters are very massive, hydrogen-burning stars. Our findings suggest that the proximity to the Eddington limit is the physical reason for the onset of Wolf-Rayet type mass loss. This means that, e.g. in stellar evolution models, the Wolf-Rayet stage should be identified by large Eddington parameters, instead of a helium-enriched surface composition. The latter is most likely only a consequence of strong mass loss, in combination with internal mixing. For very massive stars, the enhanced Gamma-dependent mass loss is responsible for the formation of late WNh subtypes with high hydrogen surface abundances, partly close to solar. Because mass loss dominates the evolution of very massive stars, we expect a strong impact of this effect on their end products, in particular on the potential formation of black holes, and Gamma-Ray Bursts, as well as the observed upper mass limit of stars.
title: A Study of Preservice Teachers' Attitudes Toward Human Rights and Unfair Labor Conditions: A Comparison of the Influence of Two Teaching Methods
Creators: name: D'sa, Benicia
Publisher: name: Utah State University
Year: 2004

description: The purpose of this study was to examine the attitudes of preservice teachers towards human rights, particularly about human rights related to labor. To assess their attitudes of human rights and unfair labor conditions, two types of presentations, (a) docudrama and discussion, and (b) lecture and discussion, were conducted. The researcher evaluated these teaching methods on their efficacy in creating an awareness of human-rights violations and labor conditions. Additionally, the participants were exposed to two types of invitations to engage in human-rights advocacy.
The study involved elementary preservice teachers and secondary preservice teachers typically at the junior undergraduate level. There were 118 participants who attended the treatment and control group and completed the surveys. The study utilized mixed methods, combining quantitative and qualitative data. Surveys addressed general human-rights attitude and advocacy along with attitudes towards labor conditions in the United States and all over the world. Posttest interviews were conducted with six participants to gain additional insights on their attitudes towards human rights and labor conditions. Descriptive statistics were used to report the means and standard deviations of the pretest and posttest scores of participants. Inferential statistics were conducted in order to determine the effectiveness of the methods used for the treatment groups compared to the control group.
Findings suggest that participants had small gains in knowledge and general attitudes towards human rights after being exposed to the treatments. However, the treatments were not effective in creating a positive significant impact on attitudes towards human rights and labor conditions or actions towards unfair labor conditions. Interviewees acknowledged poor activism on human-rights issues in the United States and felt that educating their students about these issues when they became teachers might create a change. They emphasized the relationship of knowledge about human-rights abuses to taking action on human-rights issues.
This study suggests that if schools and colleges have a role in preparing students for compassionate citizenship in a global economy, then there is a clear need for teacher educators to help develop better informed teachers regarding human rights.

description: This study attempted to identify the reading conceptions of a sample of kindergarten teachers in the state of Utah in terms of five basic approaches to beginning reading. The subjects responded to a survey instrument that included 45 statements about various beginning reading methodologies.
The descriptive data generated from the study indicates that no significant differences exist among the teachers' preferences for any of the five conceptions of reading. The data also indicates that no significant differences exist between teacher preferences for "content-centered" conceptions of reading and "pupil-centered" conceptions of reading.
This apparent lack of a preference for the "pupil-centered" instruction raises some concerns in light of recommendations presented by seven professional organizations concerning kindergarten reading instruction.
Impartial resolution of disputes in China : an intellectual property perspective
Creators: name: Zhang, Yulin
Publisher: name: University of British Columbia
Year: 2016

description: Impartial resolution of disputes puts an end to disputes, minding members of society to respect the rule of law and good social order. Civil disputes occur quite naturally between two or more persons. Such disputes can be resolved through third persons, be they judges, arbitrators or mediators. Independence and impartiality of such third persons are the corner stones for the dispute resolution system in modern society. The concept of independence and impartiality may, however, vary in different countries. The dissertation examines whether judicial impartiality is different in the current “independent trial” mode in China. Given differences in culture, legal theory and philosophy, judicial impartiality has different dimensions in countries with different systems of law, whether common law or civil law. The study is conducted through the lens of civil cases involving intellectual property rights (IPRs). Criminal cases are not part of the study. Through comparative case study and media review, the dissertation concludes that differences lie in the standards for impartiality in the corrective justice system in China. Drawing on Canadian case law, traditional philosophy and IPR case studies in China, the dissertation explores the building blocks of judicial impartiality and identifies four standards for judicial impartiality: avoiding conflict of interests, procedural due process, substantive justice and consensus-based impartiality, in addition to the “time” element of impartiality. Despite the differences, observable similarities in the dimensions of judicial impartiality exist in the dispute resolution processes. Based on the findings, I argue that impartiality as well as IPR protection should be raised to the Constitutional level in China. International high standards for impartiality ought to be adopted, while Confucian teachings can be gradually upgraded to fit with equality-based justice administration in the on-going judicial reform in China. With the study of the legal reasoning of judgments in IPR cases, I offer perspectives to illustrate the need to uphold judicial impartiality as a system requirement. I contribute to the contextualized interpretation of judicial independence for the rule of law in China and contribute to the standard building for judicial impartiality in connection with administration of justice in China.

description: There exist a relation between the Klein-Gordon and the Dirac equations with scalar and vector potentials of equal magnitude (SVPEM) and the Schrodinger equation. We obtain the relativistic energy spectrum for the four Smorodinsky-Winternitz systems from the quasi-Hamiltonian and the quadratic algebras obtained by Daskaloyannis in the non-relativistic context. We point out how results obtained in context of quantum superintegrable systems and their polynomial algebras may be applied to the quantum relativistic case. We also present the symmetry algebra of the Dirac equation for these four systems and show that the quadratic algebra obtained is equivalent to the one obtained from the quasi-Hamiltonian.

description: Bangla alphabet has a large number of letters, for this it is complicated to type faster using Bangla keyboard. The proposed keyboard will maximize the speed of operator as they can type with both hands parallel. Association rule of data mining to distribute the Bangla characters in the keyboard is used here. The frequencies of data consisting of monograph, digraph and trigraph are analyzed, which are derived from data wire-house, and then used association rule of data mining to distribute the Bangla characters in the layout. Experimental results on several data show the effectiveness of the proposed approach with better performance. This paper presents an optimal Bangla Keyboard Layout, which distributes the load equally on both hands so that maximizing the ease and minimizing the effort.

description: Detection thresholds in polarized intensity and polarization bias correction are investigated for surveys where the polarization information is obtained from RM synthesis. Considering unresolved sources with a single rotation measure, a detection threshold of $8 σ_{QU}$ applied to the Faraday spectrum will retrieve the RM with a false detection rate less than $10^{-4}$, but polarized intensity is more strongly biased than Ricean statistics suggest. For a detection threshold of $5 σ_{QU}$, the false detection rate increases to ~4%, depending also on $λ^2$ coverage and the extent of the Faraday spectrum. Non-Gaussian noise in Stokes Q and U due to imperfect imaging and calibration can be represented by a distribution that is the sum of a Gaussian and an exponential. The non-Gaussian wings of the noise distribution increase the false detection rate in polarized intensity by orders of magnitude. Monte-Carlo simulations assuming non-Gaussian noise in Q and U, give false detection rates at $8 σ_{QU}$ similar to Ricean false detection rates at $4.9 σ_{QU}$.

Investigating limited view problem in photoacoustic tomography

description: Photoacoustic (PA) imaging is a new biomedical imaging modality that is based on the PA effect. In the PA effect, nanosecond short pulsed laser light illuminates on tissue and is absorbed by optical absorbers, which undergo a temporary temperature rise. The illuminated region experiences thermo-elastic expansion and engenders an abrupt and localized pressure variation. This transient variation causes a PA wave to propagate from the absorber outward through the tissue to the surface for detection by an ultrasound transducer. The detected PA signal can then be used to estimate the initial pressure distribution. PA imaging is an absorption-based modality which is capable of providing the optical property of the illuminated tissue while achieving deep imaging penetration compared with conventional optical imaging. Meanwhile, the PA image can also provide a similar spatial resolution as ultrasound imaging. Photoacoustic tomography (PAT) is the most widely used imaging mode in PA imaging due to its simplicity and versatility. One major drawback in PAT is that the reconstruction algorithm required to estimate the initial pressure demands a large detection view angle for exact reconstruction, which is typically impractical in clinical applications. Our goal of this thesis is to develop a novel methodology to increase the detection view angle by using two linear array transducers at different orientations. The relative position between the two transducers needs to be calibrated in order to combine the received signal from the two transducers. A new calibration approach is developed by using the ultrasound modality. The efficacy of the calibration method is demonstrated by both simulation and experiment. With increased detection view angle, the reconstructed image indicates more complete tissue structures compared with the one acquired by a single transducer. By combining the PAT images from the two transducers, an improvement on the image quality through complementing the structural information is achieved. Our approach does not require a calibration phantom, which can largely simplify the calibration process and shorten the acquisition time. The use of linear array transducers and the flexibility of positioning the transducers to fit tissue geometry make this approach promising for clinical applications.
On the possibility to measure nuclear matrix elements of neutrinoless double beta decay in charge-exchange reactions

description: As shown in Ref.\cite{Rod09}, the Fermi nuclear matrix element $M^{0ν}_F$ of neutrinoless double beta ($0νββ$) decay can be reconstructed if one is able to measure the isospin-forbidden single Fermi transition matrix element from the ground state of the final nucleus to the isobaric analog state (IAS) of the initial nucleus, for instance by means of charge-exchange reactions of the $(n,p)$-type. Here, simple estimates for $^{82}$Se are made which show that indeed the tiny cross section $σ_{np}(0_f^+\to IAS)$ is dominated by the admixture of the double IAS in the ground state of the final nucleus provided that the isospin mixing is weak and can be treated perturbatively. A measurement of such a cross section would definitely be a very difficult task, but it can advance a lot our knowledge of the $0νββ$ nuclear matrix element.

description: Synopsis: This work is devoted to morphosyntactic processing in the earliest stages of L2 Polish. The target structure taken into consideration is the morphosyntactic opposition between the nominative and accusative case, respectively corresponding to the subject and object function. This is the first book-length work devoted to the VILLA project, a large multi-national initiative within which 90 adult learners took part in a first-exposure, 14-hour Polish course under controlled input conditions. As participants had never been exposed to Polish or other Slavic languages, the experiment portrays the very first contact with a completely new target language; moreover, since the learners were evenly distributed among five L1 groups, L1 interference can also be investigated in depth. In addition to an in-depth analysis of the effect of input properties on morpho-syntactic processing, the book discusses sensitive methodological points such as the role of semantics in semi-spontaneous production as well as the impact of elicitation techniques.

description: Infalling motions were detected and modeled toward this source. A mean infall velocity of 0.5 km/s with an infall mass rate of 5x10^-3 Solar masses per year was obtained. Also, a previously estimated value for the magnetic field strength in the plane of the sky was refined to be 855 micro Gauss which we used to calculate a mass-to-magnetic flux ratio of 1.9, or super-critical. The virial mass from turbulent motions was also calculated finding Mvir=563 solar masses, which gives a ratio of Msubmm/Mvir=5.9. Both values strongly suggest that this clump must be in a state of gravitational collapse.

description: We investigate numerically with Hylleraas coordinates the frequency dependence of the carrier-envelope phase (CEP) effect on bound-bound transitions of helium induced by an ultrashort laser pulse of few cycles. We find that the CEP effect is very sensitive to the carrier frequency of the laser pulse, occurring regularly even at far-off resonance frequencies. By analyzing a two-level model, we find that the CEP effect can be attributed to the quantum interference between neighboring multi-photon transition pathways, which is made possible by the broadened spectrum of the ultrashort laser pulse. A general picture is developed along this line to understand the sensitivity of the CEP effect to laser's carrier frequency. Multi-level influence on the CEP effect is also discussed.

description: We formulate the Babinet Principle (BP) as a relation between the scattering amplitudes for electromagnetic waves, and combine it with multiple scattering techniques to derive new properties of Casimir forces. We show that the Casimir force exerted by a planar conductor or dielectric on a self- complementary perforated planar mirror is approximately half that on a uniform mirror independent of the distance between them. The BP suggests that Casimir edge effects are anomalously small, supporting results obtained earlier in special cases. Finally, we illustrate how the BP can be used to estimate Casimir forces between perforated planar mirrors.
