description: For a perfect fluid, pressure $p$ and energy density $ρ$ are related via the equation of state (EOS) $ω= p/ρ$, where $ω$ is the EOS parameter, being its interpretation usually constrained to a numerical value for each universe era. Here, based on the Mie-Grüneisen EOS, we show that $ω$ is recognized as the effective Grüneisen parameter $Γ_{eff}$, whose singular contribution, the so-called Grüneisen ratio $Γ$, quantifies the barocaloric effect. Our analysis suggests that the negative $p$ associated with dark-energy implies a metastable state and that in the dark-energy-dominated era $ω$ is time-dependent, which reinforces recent proposals of a time-dependent cosmological constant. Furthermore, we demonstrate that $Γ_{eff}$ is embodied in the energy-momentum stress tensor in the Einstein field equations, enabling us to analyse, in the frame of an imperfect fluid picture, anisotropic effects of the universe expansion. We propose that upon going from decelerated- to accelerated-expansion, a phase transition-like behavior can be inferred. Yet, our analysis in terms of entropy, $Γ$, and a by us adapted version of Avramov/Casalini's model to Cosmology unveil hidden aspects related to the expansion of the universe. Our findings pave the way to interpret cosmological phenomena in connection with concepts of condensed matter Physics via $Γ_{eff}$.

PROFIT: a new alternative for emission-line PROfile FITting

description: I briefly describe a simple routine for emission-line profiles fitting by Gaussian curves or Gauss-Hermite series. The PROFIT (line-PROfile FITting) routine represent a new alternative for use in fits data cubes, as those from Integral Field Spectroscopy or Fabry-Perot Interferometry, and may be useful to better study the emission-line flux distributions and gas kinematics in distinct astrophysical objects, such as the central regions of galaxies and star forming regions. The PROFIT routine is written in IDL language and is available at http://www.ufsm.br/rogemar/software.html. The PROFIT routine was used to fit the [Fe II]1.257um emission-line profiles for about 1800 spectra of the inner 350 pc of the Seyfert galaxy Mrk1066 obtained with Gemini NIFS and shows that the line profiles are better reproduced by Gauss-Hermite series than by the commonly used Gaussian curves. The two-dimensional map of the h_3 Gauss-Hermite moment shows its highest absolute values in regions close to the edge of the radio structure. These high values may be originated in an biconical outflowing gas associated with the radio jet - previously observed in the optical [O III] emission. The analysis of this kinematic component indicates that the radio jet leaves the center of the galaxy with the north-west side slightly oriented towards us and the south-east side away from us, being partially hidden by the disc of the galaxy.

title: Multisite adaptive computation offloading for mobile cloud applications
Creators: name: Sulaiman, Dawand Jalil
Publisher: name: University of St Andrews
Year: 2020

description:
The sheer amount of mobile devices and their fast adaptability have contributed to the proliferation of modern advanced mobile applications. These applications have characteristics such as latency-critical and demand high availability. Also, these kinds of applications often require intensive computation resources and excessive energy consumption for processing, a mobile device has limited computation and energy capacity because of the physical size constraints. The heterogeneous mobile cloud environment consists of different computing resources such as remote cloud servers in faraway data centres, cloudlets whose goal is to bring the cloud closer to the users, and nearby mobile devices that can be utilised to offload mobile tasks. Heterogeneity in mobile devices and the different sites include software, hardware, and technology variations. Resource-constrained mobile devices can leverage the shared resource environment to offload their intensive tasks to conserve battery life and improve the overall application performance. However, with such a loosely coupled and mobile device dominating network, new challenges and problems such as how to seamlessly leverage mobile devices with all the offloading sites, how to simplify deploying runtime environment for serving offloading requests from mobile devices, how to identify which parts of the mobile application to offload and how to decide whether to offload them and how to select the most optimal candidate offloading site among others. To overcome the aforementioned challenges, this research work contributes the design and implementation of MAMoC, a loosely coupled end-to-end mobile computation offloading framework. Mobile applications can be adapted to the client library of the framework while the server components are deployed to the offloading sites for serving offloading requests. The evaluation of the offloading decision engine demonstrates the viability of the proposed solution for managing seamless and transparent offloading in distributed and dynamic mobile cloud environments.

Impurity bands in semiconductors
Creators: name: Tang, Tun-Hsu
Publisher: name: University of British Columbia
Year: 2011

description: The onset of concentration broadening of the impurity energy band, in silicon doped with an acceptor and the increase of bandwidth with increasing impurity concentration found experimentally (White 1967) are in disagreement with Baltensperger’s theory (1953). There are two reasons to account for this discrepancy. What was compared previously was actually two different quantities: the experimental half-width of the impurity band and the theoretical full-width of the band. Besides,, the assumptions on which Baltensperger's theory is based, that the impurities are hydrogen-like and arranged on a regular array is not justified in the present problem. The comparison of experimental and theoretical half-widths does not make the discrepancy vanish. We suggest a new way to tackle this problem theoretically by combining the impurity wave functions found by Schechter (1962) and the Green’s function technique and the graphical method presented by Matsubara and Toyozawa (1962).

subject: 510

description: The dynamics of the atmosphere and ocean involves a broad range of spatial and temporal scales, many of which emerge through complex nonlinear mechanisms from forcings at very different scales. This poses major challenges for the numerical prediction of the weather, ocean state and climate: many processes have scales that are too small to be resolved yet they play an essential role in determining large-scale features. This workshop examined how modern mathematical methods – ranging from multiscale asymptotics to adaptive numerical methods and stochastic modelling – can be applied to represent the large-scale impact of these small-scale processes and improve both deterministic and probabilistic predictions.

description: Within the last decade image and geometry processing have become increasingly rigorous with solid foundations in mathematics. Both areas are research fields at the intersection of different mathematical disciplines, ranging from geometry and calculus of variations to PDE analysis and numerical analysis. The workshop brought together scientists from all these areas and a fruitful interplay took place. There was a lively exchange of ideas between geometry and image processing applications areas, characterized in a number of ways in this workshop. For example, optimal transport, first applied in computer vision is now used to define a distance measure between 3d shapes, spectral analysis as a tool in image processing can be applied in surface classification and matching, and so on. We have also seen the use of Riemannian geometry as a powerful tool to improve the analysis of multivalued images. This volume collects the abstracts for all the presentations covering this wide spectrum of tools and application domains.

description: Excerpts from the report: Most of the world's supply of peppermint and spearmint oils comes from mint grown in Indiana, Michigan, Oregon, Washington, and Wisconsin. The oil is the principal product of the mint crop, although fresh and dried mint leaves are used in the preparation of foods and beverages. As mint oil is used in only a few products, the market for peppermint and spearmint oils will continue to be steady, although not in great demand. Peppermint oil is used to flavor chewing gum, candy, toothpaste, and medicine, in which the oil masks unpleasant flavors and odors. Spearmint oil has a smaller market and is used mostly to flavor chewing gum and toothpaste.

Subjects: subject: Konferenzschrift

description: Self-adaptive numerical methods provide a powerful and automatic approach in scientific computing. In particular, Adaptive Mesh Refinement (AMR) algorithms have been widely used in computational science and engineering and have become a necessary tool in computer simulations of complex natural and engineering problems. The key ingredient for success of self-adaptive numerical methods is a posteriori error estimates that are able to accurately locate sources of global and local error in the current approximation. The workshop creates a forum for junior and senior researchers in numerical analysis and computational science and engineering to discuss recent advances, initiates future research projects, and establishes new collaborations on convergence theory of adaptive numerical methods and on the construction and analysis of efficient, reliable, and robust a posteriori error estimators for computationally challenging problems.
Interpreting the Transmission Windows of Distant Quasars

subject: FOS: Physical sciences

description: We propose the Apparent Shrinking Criterion (ASC) to interpret the spatial extent, R_w, of transmitted flux windows in the absorption spectra of high-z quasars. The ASC can discriminate between the two regimes in which R_w corresponds either to the physical size, R_HII, of the quasar HII region, or to the distance, R^{max}_w, at which the transmitted flux drops to =0.1 and a Gunn-Peterson (GP) trough appears. In the first case (HR regime), one can determine the IGM mean HI fraction, x_HI; in the second (PR regime), the value of R_w allows to measure the local photoionization rate and the local enhancement of the photoionization rate, Gamma_G, due to nearby/intervening galaxies. The ASC has been tested against radiative transfer+SPH numerical simulations, and applied to 15 high-z (z>5.8) quasars sample from Fan et al. (2006). All sample quasars are found to be in the PR regime; hence, their observed spectral properties (inner flux profile, extent of transmission window) cannot reliably constrain the value of x_HI. Four sample quasars show evidence for a local enhancement (up to 50%) in the local photoionization rate possibly produced by a galaxy overdensity. We discuss the possible interpretations and uncertainties of this result.

description: A main goal of single-molecule experiments is to evaluate equilibrium free energy differences by applying fluctuation relations to repeated work measurements along irreversible processes. We quantify the error that is made in a free energy estimate by means of the Jarzynski equality when the accumulated work expended on the whole system (including the instrument) is erroneously replaced by the work transferred to the subsystem consisting of the sole molecular construct. We find that the error may be as large as 100%, depending on the number of experiments and on the bandwidth of the data acquisition apparatus. Our theoretical estimate is validated by numerical simulations and pulling experiments on DNA hairpins using optical tweezers.

description: Protein compartmentalization in the frame of a liquid-liquid phase separation is a key mechanism to optimize spatiotemporal control of biological systems. Such a compartmentalization process reduces the intrinsic noise in protein concentration due to stochasticity in gene expression. Employing Flory-Huggins solution theory, Avramov/Casalini's model, and the Grüneisen parameter, we unprecedentedly propose a cellular Griffiths-like phase (CGLP), which can impact its functionality and self-organization. The here-proposed CGLP is key ranging from the understanding of primary organisms' evolution to the treatment of diseases. Our findings pave the way for an alternative Biophysics approach to investigate coacervation processes.

description: (Abridged) From photometric observations of $\sim$ 47,000 stars and spectroscopy of $\sim$ 11,000 stars, we describe the first extensive study of the stellar population of the famous Double Cluster, h and $χ$ Persei, down to subsolar masses. Both clusters have E(B-V) $\sim$ 0.52--0.55 and dM = 11.8--11.85; the halo population, while more poorly constrained, likely has identical properties. As determined from the main sequence turnoff, the luminosity of M supergiants, and pre-main sequence isochrones, ages for h Persei, $χ$ Persei and the halo population all converge on $\approx$ 14 Myr. From these data, we establish the first spectroscopic and photometric membership lists of cluster stars down to early/mid M dwarfs. At minimum, there are $\sim$ 5,000 members within 10' of the cluster centers, while the entire h and $χ$ Persei region has at least $\sim$ 13,000 and as many as 20,000 members. The Double Cluster contains $\approx$ 8,400 M$_{\odot}$ of stars within 10' of the cluster centers. We estimate a total mass of at least 20,000 M$_{\odot}$. We conclude our study by outlining outstanding questions regarding the properties of h and $χ$ Persei. From comparing recent work, we compile a list of intrinsic colors and derive a new effective temperature scale for O--M dwarfs, giants, and supergiants.

description: Background: In very advanced tongue cancer, definite radiochemotherapy (RCHT)
is often preferred over total or near total glossectomy due to organ preservation
and functionality, particularly swallowing.
Methods: This retrospective study compares the functionality and survival of 10
patients with very advanced tongue cancer who received (sub)total glossectomy with
prior or adjuvant RCHT and reconstruction by a musculocutaneous anterolateral
thigh flap. All 10 patients had comparable tongue carcinomas treated by definite
RCHT. Airway protection and swallow efficiency were evaluated by fiberoptic endoscopic
evaluation of swallowing and graded using the Rosenbek Penetration and
Aspiration Scale (PAS) and the Yale Pharyngeal Residue Severity Rating Scale (YPRS).
Results: Of 10 surgical patients, 7 were completely oralized after a mean of 17 days.
For surgical patients, PAS scores swallowing saliva (mean 1.6 versus 2.9, P = 0.04) as
well as vallecula (mean 4.0 versus 2.9, P = 0.05) and piriform sinus (mean 3.5 versus
2.5, P = 0.05) YPRS scores for saliva were significantly lower compared with definite
RCHT. Irrespective of treatment, age older than 65 years (YPRS sinus piriformis
H2O 3.4 versus 2.5, P = 0.47), body mass index less than 20 kg/m2 (PAS Jelly 4.7 versus
2.2, P = 0.015, YPRS sinus piriformis 4.0 versus 2.7, P = 0.028), and Karnovsky
index less than 80 (PAS saliva 2.8 versus 1.6, P = 0.049) were associated with worse
swallowing. Speech was intelligible in 80% of patients of both groups. Overall survival
did not differ between the surgical group and definite RCHT.
Conclusions: Patients after (sub)total glossectomy with RCHT and adequate reconstruction
with a musculocutaneous anterolateral thigh flap show equal or even better
swallowing compared with patients after definite RCHT for advanced tongue cancer.

It is shown that the boundary surface between symmetric (hypermagnetic) phase and Maxwellian phase with a broken symmetry is a membrana for the separation of the magnetic helicity. Assuming the total linking number of knots of hypermagnetic field is negative, it is proved that the helicity rising in the Maxwellian phase is left-handed.

description: We study black hole solutions in the Einstein-Gauss-Bonnet gravity with the dilaton and a negative ``cosmological constant''. We derive the field equations for the static spherically symmetric ($k=1$) and hyperbolically symmetric ($k=-1$) spacetime in general $D$ dimensions. The system has some scaling symmetries which are used in our analysis of the solutions. We find exact solutions, i.e., regular AdS solution for $k=1$ and a massless black hole solution for $k=-1$. Nontrivial asymptotically AdS solutions are obtained numerically in D=4 -- 6 and 10 dimensional spacetimes. For spherically symmetric solutions, there is the minimum horizon radius below which no solution exists in D=4 -- 6. However in D=10, there is not such lower bound but the solution continues to exist to zero horizon size. For hyperbolically symmetric solution, there is the minimum horizon radius in all dimensions. Our solution can be used for investigations of the boundary theory through AdS/CFT correspondence.

Mathematical and Algorithmic Aspects of Data Assimilation in the Geosciences

Publisher: name: Zürich : EMS Publ. House
Year: 2016
Subjects: subject: Konferenzschrift
subject: 510

description: The field of “Data Assimilation” has been driven by applications from the geosciences where complex mathematical models are interfaced with observational data in order to improve model forecasts. Mathematically, data assimilation is closely related to filtering and smoothing on the one hand and inverse problems and statistical inference on the other. Key challenges of data assimilation arise from the high-dimensionality of the underlying models, combined with systematic spatio-temporal model errors, pure model uncertainty quantification and relatively sparse observation networks. Advances in the field of data assimilation will require combination of a broad range of mathematical techniques from differential equations, statistics, machine learning, probability, scientific computing and mathematical modeling, together with insights from practitioners in the field. The workshop brought together a collection of scientists representing this broad spectrum of research strands.

description: We theoretically studied the effect of the perpendicular electric field on the thermoelectric properties of the intrinsic, n-type and p-type bismuth telluride nanowires with the growth direction [110]. The electronic structure and the wave functions were calculated by solving self-consistently the system of the Schrodinger and Poisson equations using the spectral method. The Poisson equation was solved in terms of the Newton - Raphson method within the predictor-corrector approach. The electron - electron exchange - correlation interactions were taken into account in our analysis. In the temperature range from 77 to 500 K, the dependences of the Seebeck coefficient, thermal conductivity, electron (hole) concentration, and thermoelectric figure of merit on the nanowire thickness, gate voltage, and excess hole (electron) concentration were investigated in the constant relaxation-time approximation. The results of our calculations indicate that the external perpendicular electric field can increase the Seebeck coefficient of the bismuth telluride nanowires with thicknesses of 7 - 15 nm by nearly a factor of 2 and enhance ZT by an order of magnitude. At room temperature, ZT can reach a value as high as 3.4 under the action of the external perpendicular electric field for realistic widths of the nanowires. The obtain results may open up a completely new way for a drastic enhancement of the thermoelectric figure of merit in a wide temperature range.

description: Background: Breastmilk is considered to be the ideal food for infants because of its nutritional value and bioactive components. Breastfeeding has been associated with lower risk of childhood overweight and obesity and may provide benefits to cardiometabolic health in children; however, the longer-term effects of breastfeeding on child health outcomes are not well understood among populations at high risk of health disparities. Objective/Hypothesis: Our goal is to examine the relationship between breastfeeding with child body size and cardiometabolic health outcomes in mid-childhood in a cohort of low-income African American and Dominican mother-child dyads. We hypothesized greater breastfeeding duration will be associated with lower weight, decreased risk for childhood obesity and healthier metabolic indicators. Experimental Approach: Data were from the Columbia Children’s Center for Environmental Health (CCCEH) prospective birth cohort study (n=727). Linear regression models were used to relate breastfeeding to child body size and cardiometabolic measures, adjusting for covariates. Poisson regression with robust variance estimators was used to examine associations between breastfeeding risk of child overweight and obesity, adjusting for covariates. Results: Three-quarters of the women reported ever breastfeeding their infant with only 14% of the women meeting the WHO recommendations of breastfeeding for at least 6 months. The average breastfeeding duration was 11.8 weeks. Over half of the women in the analysis were Dominican with a smaller proportion self-identifying as African-American. No breastfeeding outcomes were associated with child body size at age 7 when adjusted for covariates. Ever breastfeeding was associated with lower glucose levels [=-2.14; 95% CI: (-4.19, -0.096); p=0.04]; but was not associated with lower HOMA-IR, triglycerides, HDL, or LDL cholesterol levels. Conclusion: Breastfeeding was not associated with long term child body size in 7-year-old African American and Dominican children. Ever breastfeeding was associated with lower child fasting glucose levels at ages 8-12.5; but not other cardiometabolic indicators. Further research on the effects of breastfeeding on racial minorities especially African Americans is warranted as breastfeeding could be an important modifier to bring long-lasting health benefits and reduce health disparities.

description: Recent work on synthetic rescues has shown that the targeted deletion of specific metabolic genes can often be used to rescue otherwise non-viable mutants. This raises a fundamental biophysical question: to what extent can the whole-cell behavior of a large metabolic network be controlled by constraining the flux of one or more reactions in the network? This touches upon the issue of the number of degrees of freedom contained by one such network. Using the metabolic network of Escherichia coli as a model system, here we address this question theoretically by exploring not only reaction deletions, but also a continuum of all possible reaction expression levels. We show that the behavior of the metabolic network can be largely manipulated by the pinned expression of a single reaction. In particular, a relevant fraction of the metabolic reactions exhibits canalizing interactions, in that the specification of one reaction flux determines cellular growth as well as the fluxes of most other reactions in optimal steady states. The activity of individual reactions can thus be used as surrogates to monitor and possibly control cellular growth and other whole-cell behaviors. In addition to its implications for the study of control processes, our methodology provides a new approach to study how the integrated dynamics of the entire metabolic network emerges from the coordinated behavior of its component parts.

description: A deep level transient spectroscopy (DLTS) study of defects created by low-fluence, low-energy ion implantation for development of ion-implanted silicon field-effect transistors for spin-dependent transport experiments is presented. Standard annealing strategies are considered to activate the implanted dopants and repair the implantation damage in test metal-oxide-semiconductor (MOS) capacitors. Fixed oxide charge, interface trapped charge and the role of minority carriers in DLTS are investigated. A furnace anneal at 950 $\rm ^{o}$C was found to activate the dopants but did not repair the implantation damage as efficiently as a 1000 $\rm ^{o}$C rapid thermal anneal. No evidence of bulk traps was observed after either of these anneals. The ion- implanted spin-dependent transport device is shown to have expected characteristics using the processing strategy determined in this study.

description: We address the issue of single top production in association with a W boson at the Large Hadron Collider, in particular how to obtain an accurate description in the face of the top pair production background given that the two processes interfere with each other. We stress the advantages of an MC@NLO description, and find that for cuts used to isolate the signal, it makes sense to consider Wt as a well-defined production process in that the interference with top pair production is small, and the cross-section of the former is above the scale variation uncertainty associated with the latter. We also consider the case where both Wt and top pair production are backgrounds to a third process (Higgs boson production followed by decay to a W boson pair), and find in this context that interference issues can also be neglected. We discuss the generalization of our results to other situations, aided by a comparison between the MC@NLO approach and a calculation of the WWbb final state matched to a parton shower.

description: Recently conjectures by Schmidt and by Davenport were solved in papers by Dzmitry Badziahin, Andrew Pollington and Sanju Velani, and by Victor Beresnevich. The methods which they used are the source for a growing number of works in Diophantine approximation, fractal geometry and flows on homogeneous spaces, and their full power is still far from being well understood. The goal of this workshop was to introduce those methods to a broader audience, and to allow for an opportunity to further their development.

description: Comet 133P/Elst-Pizarro is the first-known and currently best-characterised member of the main-belt comets, a recently-identified class of objects that exhibit cometary activity but which are dynamically indistinguishable from main-belt asteroids. We report here on the results of a multi-year monitoring campaign from 2003 to 2008, and present observations of the return of activity in 2007. We find a pattern of activity consistent with the seasonal activity modulation hypothesis proposed by Hsieh et al. (2004, AJ, 127, 2997). Additionally, recomputation of phase function parameters using data in which 133P was inactive yields new IAU parameters of H_R=15.49+/-0.05 mag and G_R=0.04+/-0.05, and linear parameters of m_R(1,1,0)=15.80+/-0.05 mag and Beta=0.041+/-0.005 mag/deg. Comparison between predicted magnitudes using these new parameters and the comet's actual brightnesses during its 2002 and 2007 active periods reveals the presence of unresolved coma during both episodes, on the order of ~0.20 of the nucleus cross-section in 2002 and ~0.25 in 2007. Multifilter observations during 133P's 2007 active outburst yield mean nucleus colours of B-V=0.65+/-0.03 mag, V-R=0.36+/-0.01 mag, and R-I=0.32+/-0.01 mag, with no indication of significant rotational variation, and similar colours for the trail. Finally, while 133P's trail appears shorter and weaker in 2007 than in 2002, other measures of activity strength such as dust velocity and coma contamination of nucleus photometry are found to remain approximately constant. We attribute changes in trail strength to the timing of observations and projection effects, thus finding no evidence of any substantial decrease in activity strength between 2002 and 2007.
