description: No abstracts are to be cited without prior reference to the author.There is a high certainty that global warming is a reality. Future climate change scenarios from Global Circulation Models indicate a rise in temperature and a decline in sea-ice coverage in the Barents Sea. Coupled biological-physical models project an increase in the plankton production as a response to climate change in the area. Model studies also show that a higher primary production tends to lead to an increase in cod recruitment in the Barents Sea. This together with the expected acceleration of growth and maturation rates will lead to an increase in cod stock productivity as response to the warming. On the other hand model analyses demonstrated that cod predation in the Barents Sea ecosystem, including cannibalism, would grow due to increment in rations, as water temperature will rise. In this regard, a question of how future management of cod may have to be adapted to account for climate change impacts is of interest. Simulation study on future management of cod in the Barents Sea under different warming scenarios has been carried out using STOCOBAR cod-ecosystem coupled model. This study suggested that due to changes in cod stock productivity the adjustment of the biological reference points that are used for management would be required

description: The non-linear interaction between two mechanical resonances of the same freely suspended carbon nanotube resonator is studied. We find that in the Coulomb blockade regime, the non-linear modal interaction is dominated by single-electron-tunneling processes, and that the mode-coupling parameter can be tuned with the gate voltage, allowing both mode softening and mode stiffening behavior. This is in striking contrast to tension-induced mode coupling in strings, where the coupling parameter is positive and gives rise to a stiffening of the mode. The strength of the mode coupling in carbon nanotubes in the Coulomb blockade regime is observed to be six orders of magnitude larger than the mechanical mode coupling in micromechanical resonators.

description: No abstracts are to be cited without prior reference to the author.In the Barents Sea, capelin is a key food item for the North-East Arctic cod stock. This capelin stock has had very unstable population dynamics since 1985, with recruitment failures leading to three major collapses of the stock (>90% reduction of the stock size), resulting in decreased growth and survival of cod. Here we analyze in detail how predation and harvest affects the recruitment of capelin, using data on three different stages (i.e., larvae, zero-group and 1-year-olds) through the first 1.5 years of the capelin's life. We demonstrate that both herring predation (on capelin larvae) and cod predation (both on spawners and on offspring) has had major negative effects on capelin recruitment. Mortality is furthermore demonstrated to be strongly density-dependent, and is lower when temperatures are high – probably due to higher food availability for capelin. Harvesting maturing capelin on the way to the spawning grounds did affect the production of larvae, at least during the first half of the 1980s. However, the reduced production of larvae appears to a large extent to have been compensated by decreased density-dependent mortality on later life-stages, resulting in only minor effects on the abundance as 1-year-olds. Altogether, our study points to the importance of trophic interactions in determining the dynamic structure in high-latitude marine ecosystems

description: We derive sum rules which constrain the spectral density corresponding to the retarded propagator of the T_{xy} component of the stress tensor for three gravitational duals. The shear sum rule is obtained for the gravitational dual of the N=4 Yang-Mills, theory of the M2-branes and M5-branes all at finite chemical potential. We show that at finite chemical potential there are additional terms in the sum rule which involve the chemical potential. These modifications are shown to be due to the presence of scalars in the operator product expansion of the stress tensor which have non-trivial vacuum expectation values at finite chemical potential.

description: Like their millennial counterparts, Gen Z students are digital natives, yet they prefer to learn independently with a more visual and hands-on learning style. The use of traditional power points is not an effective learning pedagogy for this tech-savvy population. Gen Z students typically have underdeveloped in-person social behaviors and poor communication skills. Nurse educators need to prepare these future nurses by utilizing effective teaching strategies and finding ways to improve necessary communication skills. Applying interactive technology such as Nearpod, Flip, Canva, TikTok, iMovie, and PowToon for classroom activities and discussions engages the students and facilitates a learning style that is effective to the student's needs. The presentation, which will be produced utilizing Nearpod, will demonstrate how applying these platforms can engage this generation of students while enhancing critical thinking and facilitating effective communication skills. Each platform will be reviewed with exemplars of activities that can be utilized in the classroom and online to facilitate the learning needs of Gen Z students.

description: Im Rahmen von TRANSENS wurden verschiedene transdisziplinäre Ansätze zur End-lagerung hochradioaktiver Abfälle in Deutschland erprobt, um wissenschaftliches und erfahrungsbasiertes Wissen unterschiedlicher Akteure zu integrieren. In diesem Beitrag wird die Rolle und der Mehrwert der für das Projekt als extended peer group rekrutierten Arbeitsgruppe Bevölkerung (AGBe) beschrieben, die sich aus interessierten Bürger:innen zusammensetzt. Auf das mehrstufige Rekrutierungsverfahren der AGBe wird ebenso eingegangen wie auf die inhaltliche Arbeit der Gruppe, auf methodische Überlegungen zur Beobachtung von Workshops und auf die Auswertung der Zusammenarbeit zwischen Wissenschaftler:innen und AGBe-Mitgliedern. Die Ergebnisse wurden anhand von Beobachtungen und Gesprächen zusammengetragen und im weiteren Projektverlauf durch qualitative Interviews validiert. Hierbei werden zwei Forschungsfragen beantwortet, nämlich (1) ob ein vertrauensvolles Verhältnis zwischen Forschenden und Nichtforschenden möglich ist und (2) ob ein Mehr an gemeinsam erarbeitetem Wissen einen Vertrauensaufbau forciert. Wir diskutieren die Herausforderungen und Erfolge dieses transdisziplinären Ansatzes und identifizieren verschiedene Faktoren, die zu einer vertrauensvollen Arbeitsbeziehung und zu einem vielfältigen Erkenntnisgewinn beigetragen haben. Abschließend wird ein gemischtes Fazit mit positivem Ausblick gezogen.
description: This article provides an insight into the practice and potential of transdisciplinary research in the field of nuclear waste management. In the context of TRANSENS, different transdisciplinary approaches to the final disposal of high-level radioactive waste in Germany were tested in order to integrate scientific and experience-based knowledge of different actors. This article describes the role and added value of the Citizens’ Working Group (German: Arbeitsgruppe Bevölkerung, short AGBe) recruited for the project as an extended peer group consisting of interested citizens. The multi-stage recruitment process of the AGBe is discussed, as well as the content of the group's work, methodological considerations regarding the observation of workshops, and the evaluation of the cooperation between scientists and AGBe members. Two research questions are answered, namely whether a trusting relationship between researchers and non-researchers is possible, and whether an increase in jointly developed knowledge promotes the development of trust. We discuss the challenges and successes of this transdisciplinary approach and identify several factors that have contributed to a trusting working relationship and a diverse knowledge gain. The limitations of the generalizability of the results are also highlighted. Finally, a mixed conclusion with a positive outlook is drawn.

Evolution and Hydrodynamics of the Very-Broad X-ray Line Emission in SN 1987A

description: Observations of SN 1987A by the Chandra High Energy Transmission Grating (HETG) in 1999 and the XMM-Newton Reflection Grating Spectrometer (RGS) in 2003 show very broad (v-b) lines with a full-width at half-maximum (FWHM) of order 10^4 kms; at these times the blast wave was primarily interacting with the HII region around the progenitor. Since then, the X-ray emission has been increasingly dominated by narrower components as the blast wave encounters dense equatorial ring (ER) material. Even so, continuing v-b emission is seen in the grating spectra suggesting that interaction with HII region material is on-going. Based on the deep HETG 2007 and 2011 data sets, and confirmed by RGS and other HETG observations, the v-b component has a width of 9300 +/-2000 kms FWHM and contributes of order 20% of the current 0.5--2 keV flux. Guided by this result, SN 1987A's X-ray spectra are modeled as the weighted sum of the non-equilibrium-ionization (NEI) emission from two simple 1D hydrodynamic simulations, this "2x1D" model reproduces the observed radii, light curves, and spectra with a minimum of free parameters. The interaction with the HII region (rho_init \sim 130 amu/cc, +/- 15 degrees opening angle) produces the very-broad emission lines and most of the 3-10 keV flux. Our ER hydrodynamics, admittedly a crude approximation to the multi-D reality, gives ER densities of order 10^4 amu/cc, requires dense clumps (x5.5 density enhancement in \sim 30% of the volume), and it predicts that the 0.5-2 keV flux will drop at a rate of \sim 17% per year once no new dense ER material is being shocked.

description: We study the effect of sigma meson on the $D_1(2430) \to Dππ$ decay by constructing an effective Lagrangian preserving the chiral symmetry and the heavy quark symmetry. The sigma meson is included through a linear sigma model, in which both the $q\bar{q}$ and $qq\bar{q}\bar{q}$ states are incorporated respecting their different $U(1)_{A}$ transformation properties. We first fit the sigma meson mass and $σ$-$π$-$π$ coupling constant to the I=0, $S$-wave $π$-$π$ scattering data. Then, we show how the differential decay width $dΓ(D_1 \to D(ππ)_{I = 0, L =0})/d m_{ππ}$ depends on the quark structure of the sigma meson. We find that our study, combing with the future data, can give a clue to understand the sigma meson structure.

Reproductive dynamics and fingerprinting effort in a Douglas-fir seed orchard
Creators: name: Kess, Joseph Anthony
Publisher: name: University of British Columbia
Year: 2012

description: Seed orchards are the tree improvement programs’ production populations used to predictably package genetic gain and diversity achieved during the breeding cycle. Genetic gain and diversity delivered by seed orchards is calculated under the assumption of reproductive randomness, equality, and synchrony. These ideal expectations are not fulfilled by any existent seed orchards and deviations in gametic contribution by orchard parents’ makes genetic gain and diversity unpredictable. In this study, five Douglas-fir (Pseudotsuga menziesii) microsatellite markers (Slavov et al 2004) were used to genotype 66 orchard parents, 14 of which were also supplemental mass pollination (SMP) pollen donors, and 396 bulk seeds from the 2009 seed crop of a wind-pollinated Douglas-fir seed orchard. Genotype data were analyzed using the likelihood based CERVUS parentage analysis program (Kalinowski et al 2007) for full pedigree reconstruction. In this orchard, 14% of paternal gametic contributions came from outside males. Parental balance curves showed that 80% of paternal, maternal, and gametic contributions were made by 38 (58%), 34 (52%) and 37 (56%) orchard parents, indicating that the greatest gametic contribution inequality was attributable to maternal gametic contribution. Differences in gametic contribution and common ancestry between orchard parents decreased the effective number of males, females, and population size to 42, 37, and 41, lower than the census number of 66 parents. Selfing was 24.24%, higher than that reported for many Douglas-fir seed orchards. High selfing may be attributed to reproductive asynchrony or differences in parental reproductive output. Supplemental mass pollination did not result in significantly higher paternal gametic contribution. Failure of SMP may be attributed to either incorrect timing of application or competition with ambient pollen. The minimum number of genotyped seeds required for accurate contamination estimate was 150, identified by jackknife sampling of the total genotyped seed sample.

description: No abstracts are to be cited without prior reference to the author.Recruitment ecology of cod has been an important focus within the framework of GLOBEC. A large part of this work focused on understanding the spatiotemporal component of cod populations. For the early pelagic life stages, studies based on an individual-based platform have provided highly valuable insights combining oceanographic, behavioural and modelling approaches. The spatial modelling of observational data often fails to include densitydependent covariates, which for early pelagic life stages, originate from the combination of circulation patterns and eggs coming from the spawning aggregations. We performed this task combining a hydrographical particle-tracking model with spatial statistical analyses to investigate the relative contribution of hydrographical variables on the spatial distribution of cod larvae in the Barents Sea under two short-term climatic regimes in the period 1986-1991. The cod larvae distribution is modelled using eggs drifting from the spawning aggregations in the Lofoten Islands. We found that inter-annual variability in the spatial aggregations of the spawners influenced the distribution of larvae drifted. We have also shown how the spatial distribution of passive-drifting larvae can change over the two regimes (1986-1988 and 1989- 1991), being more upstream in cold periods. Though the currents pattern is the main hydrographical factor shaping the spatial distribution of larvae, the temperature modifies such distribution by affecting larvae survival. However, our study highlights the geographic extension of the temperature effect changed between warm and cold periods, with clear ecological implications in terms of growth and survival. This approach can be useful for other fish populations to further understand the underlying processes shaping the seascape of early life stages

description: Local food systems (LFS) are often viewed as development pathways for local economies due to their ability to create a multiplier effect in an economy through a significant contribution to output and job creation. There is limited information on these impacts for Tennessee. Therefore, this study measures the gross economic contributions of Tennessee’s local food system using IMPLAN’s input-output model. Results show that LFS is a crucial component of Tennessee’s economy with an estimated total economic contribution of $37.5 billion. The region’s local food system directly employs more than 99,000 people and has an income multiplier of 2.56 and a value-added multiplier of 2.06.

description: Worldwide, the human immunodeficiency virus (HIV) continuum of care involves health promotion providers (e.g., social workers and health educators) linking patients to medical personnel who provide HIV testing, primary care, and antiretroviral treatments. Regrettably, these life-saving linkages are not always made consistently and many patients are not retained in care. To design, test and implement effective interventions, we need to first identify key factors that may improve linkage-making. To help close this gap, we used in-depth interviews with 20 providers selected from a sample of 250 participants in a mixed-method longitudinal study conducted in New York City (2012–2017) in order to examine the implementation of HIV services for at-risk populations. Following a sociomedical framework, we identified provider-, interpersonal- and environmental-level factors that influence how providers engage patients in the care continuum by linking them to HIV testing, HIV care, and other support services. These factors occurred in four domains of reference: Providers’ Professional Knowledge Base; Providers’ Interprofessional Collaboration; Providers’ Work-Related Changes; and Best Practices in a Competitive Environment. Of particular importance, our findings show that a competitive environment and a fear of losing patients to other agencies may inhibit providers from engaging in linkage-making. Our results suggest relationships between factors within and across all four domains; we recommend interventions to modify factors in all domains for maximum effect toward improving care continuum linkage-making. Our findings may be applicable in different areas of the globe with high HIV prevalence.

The strength of such a CP violation depends on the size of the CEDM, d'_c. We propose two effective ways of testing it from the large sample of psi'->J/psi+pi(+)+pi(-) at the Beijing Spectrometer, and the obtained result, |d'_c|<3X10^{-14} e cm (95% C.L.), gives the first experimentally determined upper bound on the CEDM of the c quark.

description: We propose a mechanism for binding of diatomic ligands to heme based on a dynamical orbital selection process. This scenario may be described as bonding determined by local valence fluctuations. We support this model using linear-scaling first-principles calculations, in combination with dynamical mean-field theory, applied to heme, the kernel of the hemoglobin metalloprotein central to human respiration. We find that variations in Hund's exchange coupling induce a reduction of the iron 3d density, with a concomitant increase of valence fluctuations. We discuss the comparison between our computed optical absorption spectra and experimental data, our picture accounting for the observation of optical transitions in the infrared regime, and how the Hund's coupling reduces, by a factor of five, the strong imbalance in the binding energies of heme with CO and O_2 ligands.

Using the notion of generalised connection and torsion, we introduce the analogue of the Levi-Civita connection, and derive the corresponding tensorial measures of generalised curvature. We show how, to leading order in the fermion fields, these structures allow one to rewrite the action, equations of motion and supersymmetry variations in a simple, manifestly $\mathit{Spin}(9,1)\times\mathit{Spin}(1,9)$-covariant form.

description: No abstracts are to be cited without prior reference to the author.The “recruitment problem” - trying to understand what regulates recruitment variability in marine fish populations - has been the number one issue in fisheries science since the early twentieth century. Intuitively, the size of the spawning stock should influence recruitment. In practice, however, the relationship is most often weak, complicating fisheries management and causing much controversy. Thus, the value of fitting stock-recruitment relationships for marine fish populations could be questioned. Nonetheless, the weak connections found may be due to insufficient data or models, and a general denial of meaningful stock-recruitment relationships would have rather alarming consequences on the science of fish population dynamics

description: As data are increasingly modeled as graphs for expressing complex relationships, the tree pattern query on graph-structured data becomes an important type of queries in real-world applications. Most practical query languages, such as XQuery and SPARQL, support logical expressions using logical-AND/OR/NOT operators to define structural constraints of tree patterns. In this paper, (1) we propose generalized tree pattern queries (GTPQs) over graph-structured data, which fully support propositional logic of structural constraints. (2) We make a thorough study of fundamental problems including satisfiability, containment and minimization, and analyze the computational complexity and the decision procedures of these problems. (3) We propose a compact graph representation of intermediate results and a pruning approach to reduce the size of intermediate results and the number of join operations -- two factors that often impair the efficiency of traditional algorithms for evaluating tree pattern queries. (4) We present an efficient algorithm for evaluating GTPQs using 3-hop as the underlying reachability index. (5) Experiments on both real-life and synthetic data sets demonstrate the effectiveness and efficiency of our algorithm, from several times to orders of magnitude faster than state-of-the-art algorithms in terms of evaluation time, even for traditional tree pattern queries with only conjunctive operations.

description: To supplement the already known classification of traces on classical pseudodifferential operators, we present a classification of traces on the algebras of odd-class pseudodifferential operators of non-positive order acting on smooth functions on a closed odd-dimensional manifold. By means of the one to one correspondence between continuous traces on Lie algebras and determinants on the associated regular Lie groups, we give a classification of determinants on the group associated to the algebra of odd-class pseudodifferential operators with fixed non-positive order. At the end we discuss two possible ways to extend the definition of a determinant outside a neighborhood of the identity on the Lie group associated to the algebra of odd-class pseudodifferential operators of order zero.

Parks--Cost effectiveness

description: Objectives. To examine health benefits and cost-effectiveness of implementing a freeway deck park to increase urban green space.

Methods. Using the Cross-Bronx Expressway in New York City as a case study, we explored the cost-effectiveness of implementing deck parks. We built a microsimulation model that included increased exercise, fewer accidents, and less pollution as well as the cost of implementation and maintenance of the park. We estimated both the quality-adjusted life years gained and the societal costs for 2017.

Results. Implementation of a deck park over sunken parts of Cross-Bronx Expressway appeared to save both lives and money. Savings were realized for 84% of Monte Carlo simulations.

Conclusions. In a rapidly urbanizing world, reclaiming green space through deck parks can bring health benefits alongside economic savings over the long term.

Public Health Implications. Policymakers are seeking ways to create cross-sectorial synergies that might improve both quality of urban life and health. However, such projects are very expensive, and there is little information on their return of investment. Our analysis showed that deck parks produce exceptional value when implemented over below-grade sections of road.

description: Many participants in Massive Open Online Courses are full-time employees seeking greater flexibility in their time commitment and the available learning paths. We recently addressed these requirements by splitting up our 6-week courses into three 2-week modules followed by a separate exam. Modularizing courses offers many advantages: Shorter modules are more sustainable and can be combined, reused, and incorporated into learning paths more easily. Time flexibility for learners is also improved as exams can now be offered multiple times per year, while the learning content is available independently. In this article, we answer the question of which impact this modularization has on key learning metrics, such as course completion rates, learning success, and no-show rates. Furthermore, we investigate the influence of longer breaks between modules on these metrics. According to our analysis, course modules facilitate more selective learning behaviors that encourage learners to focus on topics they are the most interested in. At the same time, participation in overarching exams across all modules seems to be less appealing compared to an integrated exam of a 6-week course. While breaks between the modules increase the distinctive appearance of individual modules, a break before the final exam further reduces initial interest in the exams. We further reveal that participation in self-paced courses as a preparation for the final exam is unlikely to attract new learners to the course offerings, even though learners' performance is comparable to instructor-paced courses. The results of our long-term study on course modularization provide a solid foundation for future research and enable educators to make informed decisions about the design of their courses.

description: The wine industry produces large amounts of liquid and solid organic wastes in the form of lees and pomace. The high concentration of organics, measured as chemical oxygen demand (COD) contained in these wastes complicates disposal or reuse, however, this same characteristic makes them ideal for anaerobic conversion to methane gas, a cleaner energy source than fossil fuels. The main objective of this research was to determine whether these wastes could be treated anaerobically to produce methane, and to isolate ideal conditions for conversion. Research activities included 1) a waste audit of a medium-sized winery to determine the type and quantities of organic waste produced, 2) characterization of the waste, 3) enrichment of anaerobic cultures, 4) a set of biochemical methane potential (BMP) tests to assess the impact of different waste combinations on methane yields, and 5) a second set of BMP tests to assess the impact on methane yields by different waste types at different food to microorganism ratios (F/M) and at different waste combinations. The research yielded the following general results. 1) Two anaerobic cultures were successfully enriched to degrade lees and tartaric acid. 2) BMP testing showed the enriched cultures could be overwhelmed by an excess of lees, and pomace could be degraded to some extent (~ 30% COD) but over long periods of time (> 100 days). Both wastes were successfully converted to methane but at different rates. Post-experiment analysis showed an F/M ratio of 5 might be ideal for methane conversion. 3) Another set of BMP tests revealed lees was converted to methane more efficiently at an F/M ratio of 4, yielding 0.25 ± 0.01 L CH4/g COD consumed. An ideal F/M ratio was not identified for pomace. Co-treatment of lees and pomace at different combinations did not reveal an ideal mix as all three combinations tested were statistically similar in yields, an average of 0.13 ± 0.02 L CH4/g COD consumed. It was found that pomace had inhibited methanogenesis in the co-treatment tests; however, further research is needed to determine the cause and extent of this inhibition.

description: We investigate the quantum anomalous Hall effect in a mixture of ultra-cold neutral bosons and fermions held on a hexagonal optical lattice. In the strong atom-atom interaction limit, composite fermions composed of one fermion with bosons or bosonic holes in the mixture are formed. Such composite fermions have already been generated successfully in experiment [Nat. Phys. {\bf 7}, 642 (2011)]. Here we predict that this kind of composite fermions may provide a realization of the quantum anomalous Hall effect by tuning the atom-atom interaction or the filling of the bosons in the mixture. We also discuss the corresponding experimental signatures of the quantum anomalous Hall effect in the Bose-Fermi mixture on hexagonal optical lattice.

description: A number of open questions in human evolutionary genetics would become tractable if we were able to directly measure evolutionary fitness. As a step towards this goal, we developed a method to examine whether individual genetic variants, or sets of genetic variants, currently influence viability. The approach consists in testing whether the frequency of an allele varies across ages, accounting for variation in ancestry. We applied it to the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort and to the parents of participants in the UK Biobank. Across the genome, we found only a few common variants with large effects on age-specific mortality: tagging the APOE ε4 allele and near CHRNA3. These results suggest that when large, even late-onset effects are kept at low frequency by purifying selection. Testing viability effects of sets of genetic variants that jointly influence 1 of 42 traits, we detected a number of strong signals. In participants of the UK Biobank of British ancestry, we found that variants that delay puberty timing are associated with a longer parental life span (P~6.2 × 10−6 for fathers and P~2.0 × 10−3 for mothers), consistent with epidemiological studies. Similarly, variants associated with later age at first birth are associated with a longer maternal life span (P~1.4 × 10−3). Signals are also observed for variants influencing cholesterol levels, risk of coronary artery disease (CAD), body mass index, as well as risk of asthma. These signals exhibit consistent effects in the GERA cohort and among participants of the UK Biobank of non-British ancestry. We also found marked differences between males and females, most notably at the CHRNA3 locus, and variants associated with risk of CAD and cholesterol levels. Beyond our findings, the analysis serves as a proof of principle for how upcoming biomedical data sets can be used to learn about selection effects in contemporary humans.

description: No abstracts are to be cited without prior reference to the author.The Baltic Sea experienced an ecosystem regime shift in the late 1980ies with great changes in food web dynamics and a decrease of the Eastern Baltic cod stock biomass to a historically low level in 1992. This decline was caused by high fishing pressure combined with a recruitment failure (Köster et al. 2003; Möllmann et al. 2008). In addition, the main spawning time of Eastern Baltic cod shifted from April-June to July-August in the early 1990ies. Effects of temperature and demographic changes in the cod stock do not fully explain this shift (Wieland et al. 2000). However, also the prey composition and condition of sprat and herring being the main prey of Baltic cod changed during this period influencing cod dietary lipid intake. As cod uses liver lipid stores for reproduction changed lipid intake or deficiency of essential fatty acids (EFA) could influence ovarian development and thereby the spawning time.

Meriones meridianus

description: Meriones meridianus (Pallas, 1773) Records. First specimen was captured by live trapping in May 14, 2017 (43°11.039′N, 105°45.276′ E – site LSH16 – time 8:00 am), and subsequently in SHC5, LSH6 (Table 4); Figure 6N. Identification. We based the identification on morphometric and qualitative characters. The tail is relatively longer than the head and body. It differs from Meriones unguiculatus in having a less-developed tuft of the tail; the tuft is sometimes absent. The dorsal part of the tail is yellowish brown and its ventral part is light yellow. The sole of the hind feet is covered with hairs. The claws are white with a reddish upper part. The underbelly is white (Darvish 2009, Smith et al. 2010).

description: We investigate the electron spin dephasing in the presence of spin phase recovering by a serried $π$-pulse sequence in $n$-type (001) GaAs quantum wells in a wide range of temperature and density regimes. Our numerical calculation is based on the kinetic spin Bloch equation approach with all the relevant scatterings explicitly included. We find that the rephasing pulse sequence with a long inter-pulse spacing only has a marginal influence on the spin lifetime in both the strong and weak scattering limits. We show that the spin lifetime can be significantly increased by reducing the inter-pulse spacing. More interestingly, we show that the temperature and density dependences of the spin lifetime in the case of short inter-pulse spacing coincide with those of the momentum scattering time in the low temperature regime, where nonmonotonic behaviors can appear. The origin of this feature is that the scattering under the quick rephasing manipulation mainly performs as the source of the dephasing channel instead of the key to suppress the inhomogeneous broadening. The contributions of the relevant scattering mechanisms are also discussed.

description: No abstracts are to be cited without prior reference to the author.Vertical distribution of fish eggs and larvae is a key factor for transport and retention of the offspring, and for problems linked to mixing/separation between populations, and hence for mechanism maintaining genetic differentiation among local populations, in combination with high site fidelity and natal homing of older cod. The vertical distribution is determined by the combined effects of local salinity structure of the ambient water and by the specific gravity of the eggs. The specific gravity of the eggs is determined their bio-physical characteristics. We have studied bio-physical properties of Norwegian Coastal cod (Gadus morhua) eggs from different areas (Porsangen, Tysfjord, and Helgeland).
