description: Application designers often face the question of whether to store large objects in a filesystem or in a database. Often this decision is made for application design simplicity. Sometimes, performance measurements are also used. This paper looks at the question of fragmentation - one of the operational issues that can affect the performance and/or manageability of the system as deployed long term. As expected from the common wisdom, objects smaller than 256KB are best stored in a database while objects larger than 1M are best stored in the filesystem. Between 256KB and 1MB, the read:write ratio and rate of object overwrite or replacement are important factors. We used the notion of "storage age" or number of object overwrites as way of normalizing wall clock time. Storage age allows our results or similar such results to be applied across a number of read:write ratios and object replacement rates.

description: Coherent control of collective spontaneous emission in an extended atomic ensemble resonantly interacting with single-photon wave packets is analyzed. A scheme for coherent manipulation of collective atomic states is developed such that superradiant states of the atomic system can be converted into subradiant ones and vice versa. Possible applications of such a scheme for optical quantum state storage and single-photon wave packet shaping are discussed. It is shown that also in the absence of inhomogeneous broadening of the resonant line, single-photon wave packets with arbitrary pulse shape may be recorded as a subradiant state and reconstructed even although the duration of the wave packets is larger than the superradiant life-time. Specifically the applicability for storing time-bin qubits, which are used in quantum cryptography is analyzed.

description: We discuss the spin-wave interaction in two-dimensional (2D) Heisenberg ferromagnet (FM) with dipolar forces at $T_C\gg T\ge0$ using 1/S expansion. A comprehensive analysis is carried out of the first 1/S corrections to the spin-wave spectrum. In particular, similar to 3D FM discussed in our previous paper A.V. Syromyatnikov, PRB {\bf 74}, 014435 (2006), we obtain that the spin-wave interaction leads to the {\it gap} in the spectrum $ε_{\bf k}$ renormalizing greatly the bare gapless spectrum at small momenta $k$. Expressions for the spin-wave damping $Γ_{\bf k}$ are derived self-consistently and it is concluded that magnons are well-defined quasi-particles in both quantum and classical 2D FMs at small $T$. We observe thermal enhancement of both $Γ_{\bf k}$ and $Γ_{\bf k}/ε_{\bf k}$ at small momenta. In particular, a peak appears in $Γ_{\bf k}$ and $Γ_{\bf k}/ε_{\bf k}$ at small $k$ and at any given direction of $\bf k$. If $S\sim1$ the height of the peak in $Γ_{\bf k}/ε_{\bf k}$ is not larger than a value proportional to $T/D\ll1$, where $D$ is the spin-wave stiffness. In the case of large spins $S\gg1$ the peak in $Γ_{\bf k}/ε_{\bf k}$ cannot be greater than that of the classical 2D FM found at $k=0$ which height is small only {\it numerically}: $Γ_{\bf 0}/ε_{\bf 0}\approx0.16$ for the simple square lattice. Frustrating next-nearest-neighbor exchange coupling increases $Γ_{\bf 0}/ε_{\bf 0}$ in classical 2D FM only slightly. We find expressions for spin Green's functions and the magnetization. The latter differs from the well-known result by S.V. Maleev, Sov. Phys. JETP {\bf 43}, 1240 (1976). The effect of the exchange anisotropy is also discussed briefly.

description: Backward elastic electron scattering from odd-A nuclear targets is characterized by magnetic form factors containing precise information on the nuclear structure. We study the sensitivity of the magnetic form factors to structural effects related to the evolution and shape transitions in both isotopic and isotonic chains. Calculations of magnetic form factors are performed in the plane-wave Born approximation. The nuclear structure is obtained from a deformed self-consistent mean-field calculation based on a Skyrme HF+BCS formalism. Collective effects are included in the cranking approximation, whereas nucleon-nucleon correlations are taken into account in the coherent density fluctuation model. The evolution of the magnetic form factors is found to exhibit signatures of shape transitions that show up in selected isotopic and isotonic chains involving both stable and unstable nuclei. Several cases are identified as suitable candidates for showing such fingerprints of shape transitions. A new generation of electron scattering experiments involving electron-radioactive beam colliders will be available in the near future, leading to a renewed interest in this field.

description: Aims: Polypharmacy is extensive in people with chronic non-cancer pain (CNCP) and many of these medications are associated with adverse effects, including sedation. The aims of this study were to: i) describe sedative load (SL) in a cohort of people with CNCP prescribed opioids, ii) assess whether SL is associated with self-reported drowsiness/fatigue iii) assess correlates of SL and; iv) assess the association of SL and ambulance use.

Methods: A total of 1,166 CNCP patients prescribed opioids were recruited from community pharmacies across Australia and completed a diary of their medication use in the past week. SL was calculated using a previously published index (number of sedative medications multiplied by the weighting for medications with sedative action). Associations with SL were examined using multivariate regression, controlling for demographic characteristics, physical and mental health, substance use and total oral morphine equivalent dose.

Results: The mean SL for the group was 3.76 (S.D.2.22) and ranged from 0-13. Fifty-five percent of the sample had used antidepressants, 28% had used benzodiazepines and 7% had used antipsychotics. SL was associated with drowsiness/fatigue but SL only explained 3% of the variance in drowsiness/fatigue. Being female, younger, unemployed, having more severe pain, anxiety/depression and a higher total oral morphine equivalent dose were associated with a higher SL. After controlling for demographics, physical and mental health comorbidities, SL was not associated with past month ambulance use.

Conclusion: Among people with CNCP, a high SL was associated with being younger, and having more severe pain and mental health comorbidities.

description: We show that two new intra-species P-wave superfluid phases appear in two-component asymmetric Fermi systems with short-range S-wave interactions. In the BEC limit, phonons of the molecular BEC induce P-wave superfluidity in the excess fermions. In the BCS limit, density fluctuations induce P-wave superfluidity in both the majority and the minority species. These phases may be realized in experiments with spin-polarized Fermi gases.

description: Relativity theory and its underlying Lorentz and CPT invariance represent key principles of physics and therefore require continued experimental scrutiny across the broadest possible range of energy scales and physical systems. Possibilities for tests of these symmetries in precision $β$-decay experiments with focus on KATRIN are investigated. It is found that countershaded departures from relativity, which represent a particular challenge to detection, are accessible in such experiments. In this context, it is argued that KATRIN would be in an excellent position to conduct the first-ever experimental search for countershaded Lorentz and CPT breaking in neutrinos.

description: We study the kinetics of the quasiparticle capture and emission process in a small superconducting island (Cooper-pair box) connected by a tunnel junction to a massive superconducting lead. At low temperatures, the charge on the box fluctuates between two states, even and odd in the number of electrons. Assuming that the odd-electron state has the lowest energy, we evaluate the distribution of lifetimes of the even- and odd-electron states of the Cooper-pair box. The lifetime in the even-electron state is an exponentially distributed random variable corresponding to a homogenous Poisson process of ``poisoning'' the island with a quasiparticle. The distribution of lifetimes of the odd-electron state may deviate from the exponential one. The deviations come from two sources - the peculiarity of the quasiparticle density of states in a superconductor and the possibility of quasiparticle energy relaxation via phonon emission. In addition to the lifetime distribution, we also find spectral density of charge fluctuations generated by capture and emission processes. The complex statistics of the quasiparticle dwell times in the Cooper-pair box may result in strong deviations of the noise spectrum from the Lorentzian form.

The effects of phonological and metaphonological intervention on the metaphonological skills of children with phonological disorders
Creators: name: Major, Eva M.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the relationships between the phonological and metaphonological skills of nineteen 3- to 5-year-old children with moderately severe to severe phonological disorders, and to observe the effects of two types of intervention on the children awareness skills. Seven metaphonological tasks were used which required children to recite nursery rhymes, to produce alliterations and rhymes, to segment disyllabic and monosyllabic words, and to change the names of objects. Children's metaphonological skills were tested (a) before intervention (b) following phonological intervention, and (c) following metaphonological plus phonological intervention. The results suggested that children's metaphonological abilities were related to their phonological and morphosyntactic production skills. Intervention outcomes indicated that both types of intervention may result in a significant increase in children's metaphonological task performance. It was further observed that children with more moderate phonological disorders and good morphosyntactic production skills tended to improve on the metaphonological tasks following phonological intervention alone. Children with more severe phonological and morphosyntactic disorders tended to increase their task performance only following phonological plus metaphonological intervention.

description: A wave pulse (be it a gravitational wave or a light wave) undergoes anomalous dispersion in a vacuum in flat spacetimes with an even number of spatial dimensions even if all the frequencies move at the same speed. Such an anomalous dispersion does not occur in spacetimes with an odd number of spatial dimensions. We study various gravity theories and show that dispersion-free propagation is possible in even number of spatial dimensions if the background is not the Minkowski but the de Sitter spacetime and the gravity theory is massive gravity with a tuned mass in terms of the cosmological constant. Mass and the cosmological constant conspire to get rid of the anomalous dispersion and restore Huygens' principle.

Molecular pneumococcal capsular typing using whole genome sequencing: moving the Streptococcus pneumoniae reference service into the genomic era
Creators: name: Kapatai, Georgia
Publisher: name: F1000Research
Year: 2015

description: Streptococcus pneumoniae isolates typically express one of 92 immunologically distinct polysaccharide capsules (serotypes). Some of these serotypes are difficult to distinguish from each other when using commercially available typing antisera and are defined as members of a serogroup.  Additional factor antisera are then required to definitively allocate serotypes within a serogroup, based on patterns of reactions. However, this method requires extensive experience and the reading of the results can be subjective.

We sequenced the genomes of 926 clinical S. pneumoniae isolates and, based on percentage sequence similarities within the polysaccharide capsule operon locus, we determined that, of the 92 serotypes, 32 could be unambiguously identified. The remaining 60 could only be allocated to one of 20 ‘genogroups’ that largely correspond to the immunologically defined serogroups. By comparing reference polysaccharide capsular locus sequences for the 92 serotypes (downloaded from NCBI), unique molecular differences were determined for serotypes within 18 of the 20 genogroups and verified using our set of 926 isolates. These differences were then used in a ‘capsular typing’ bioinformatics tool to predict serotype for 90/94 (92 + 2 molecular types/subtypes) from WGS data and up to serogroup level for types 24B, 24F and serogroup 32. Our ‘capsular typing’ tool has been validated to-date with a set of 426 isolates covering 63/94 capsular types. In 82.5% of the cases the predicted capsular type was concordant with the immunologically derived serotype. Only 2.5% of cases comprise the 4 serotypes the tool can only type to serogroup level. The remaining 15% of cases have given discordant results; in 48% of these our tools predicted to serotype level when the immunological method gave ambiguous results.

In summary, we have developed a WGS-based serotyping method that can predict capsular type to serotype level for 90/94 serotypes and to serogroup level for the remaining 4. This approach could be integrated into routine diagnostic workflows, phasing out phenotypic immunological testing. In PHE we plan on implementing this as part of the S. pneumoniae Reference Service by January 2016 following a side-by-side validation period where WGS and the standard phenotypic method are run in parallel.

description: For a successful integration of silicon in high-capacity anodes of Li-ion batteries, its intrinsic capacity decay on cycling due to severe volume swelling should be minimized. In this work, Ni-Sn intermetallics are studied as buffering matrix during reversible lithiation of Si-based anodes. Si/Ni-Sn composites have been synthetized by mechanical milling using C and Al as process control agents. Ni3Sn4, Ni3Sn2 intermetallics and their bi-phasic mixture were used as constituents of the buffering matrix. The structure, composition and morphology of the composites have been analyzed by X-ray diffraction (XRD), 119Sn Transmission Mössbauer Spectroscopy (TMS) and scanning electron microscopy (SEM). They consist of ~ 150 nm Si nanoparticles embedded in a multi-phase matrix, the nanostructuration of which improves on increasing the Ni3Sn4 amount. The electrochemical properties of the composites were analyzed by galvanostatic cycling in half-cells. Best results for practical applications are found for the bi-phasic matrix Ni3Sn4-Ni3Sn2 in which Ni3Sn4 is electrochemically active while Ni3Sn2 is inactive. Low capacity loss, 0.04 %/cycle, and high coulombic efficiency, 99.6%, were obtained over 200 cycles while maintaining a high reversible capacity above 500 mAh/g at moderate regime C/5

description: Background and aims:
There is evidence that chronic low back pain (cLBP) patients with avoidance-endurance behavior face a higher risk of treatment failure and pain maintenance. The aim of this study was to investigate the impact of avoidance-endurance model (AEM) subgroups on the treatment outcome of cLBP patients.

Methods:
137 cLBP patients were investigated before and after a 6 month training rehabilitation. Patients completed the Roland-Morris disability questionnaire, Pain Disability Index, 36-Item Short-Form Health Survey, Avoidance-Endurance Questionnaire, visual analog scale pain ratings, and performed maximum back extension tests. Outcome variables were pain intensity, disability, quality of life, back extensor torque, and avoidance-endurance behavior. The statistical methods we used include cluster analysis, chi-square tests, and mixed effect models.

Results:
24% of the patients were classified as fear-avoiders (FAR), 17% as eustress-endurers (EER), 34% as distress-endurers (DER) and 25% as adaptive responders (AR). After the intervention patients of all subgroups significantly improved in their pain and disability levels, quality of life and back extensor torque. However, FAR and DER still reported significantly lower quality of life and higher levels of fear-avoidance or endurance behavior than the other subgroups.

Conclusion:
Whereas 6 months of training led to improved bodily performance in all cLBP patients, 2 out of the 4 AEM subgroups still demonstrated inferior quality of life and negative psychological behavior patterns. Thus, rehabilitation outcome in FAR and DER could likely be optimized if interventions intended to improve quality of life and to reduce avoidance-endurance behavior were added to the treatment program.

description: Atom tunneling in the hydrogen atom transfer reaction of the 2,4,6-tri-tert-butylphenyl radical to 3,5-di-tert-butylneophyl, which has a short but strongly curved reaction path, was investigated using instanton theory. We found the tunneling path to deviate qualitatively from the classical intrinsic reaction coordinate, the steepest-descent path in mass-weighted Cartesian coordinates. To perform that comparison, we implemented a new variant of the predictor-corrector algorithm for the calculation of the intrinsic reaction coordinate. We used the reaction force analysis method as a means to decompose the reaction barrier into structural and electronic components. Due to the narrow energy barrier, atom tunneling is important in the abovementioned reaction, even above room temperature. Our calculated rate constants between 350 K and 100 K agree well with experimental values. We found a H/D kinetic isotope effect of almost 106 at 100 K. Tunneling dominates the protium transfer below 400 K and the deuterium transfer below 300 K. We compared the lengths of the tunneling path and the classical path for the hydrogen atom transfer in the reaction HCl + Cl and quantified the corner cutting in this reaction. At low temperature, the tunneling path is about 40% shorter than the classical path.

description: Recent experiments in a mixture of two hyperfine states of trapped Bose gases show behavior analogous to a spin-1/2 system, including transverse spin waves and other familiar Leggett-Rice-type effects. We have derived the kinetic equations applicable to these systems, including the spin dependence of interparticle interactions in the collision integral, and have solved for spin-wave frequencies and longitudinal and transverse diffusion constants in the Boltzmann limit. We find that, while the transverse and longitudinal collision times for trapped Fermi gases are identical, the Bose gas shows unusual diffusion anisotropy in both dipole and quadrupole modes. Moreover, the lack of spin isotropy in the interactions leads to the non-conservation of transverse spin, which in turn has novel effects on the hydrodynamic modes.

description: Triangulated meshes have become ubiquitous discrete-surface representations. In this paper we address the problem of how to maintain the manifold properties of a surface while it undergoes strong deformations that may cause topological changes. We introduce a new self-intersection removal algorithm, TransforMesh, and we propose a mesh evolution framework based on this algorithm. Numerous shape modelling applications use surface evolution in order to improve shape properties, such as appearance or accuracy. Both explicit and implicit representations can be considered for that purpose. However, explicit mesh representations, while allowing for accurate surface modelling, suffer from the inherent difficulty of reliably dealing with self-intersections and topological changes such as merges and splits. As a consequence, a majority of methods rely on implicit representations of surfaces, e.g. level-sets, that naturally overcome these issues. Nevertheless, these methods are based on volumetric discretizations, which introduce an unwanted precision-complexity trade-off. The method that we propose handles topological changes in a robust manner and removes self intersections, thus overcoming the traditional limitations of mesh-based approaches. To illustrate the effectiveness of TransforMesh, we describe two challenging applications, namely surface morphing and 3-D reconstruction.

description: Loneliness threatens public mental wellbeing during COVID-19. In response, YouTube creators participated in the #StayHome #WithMe movement (SHWM) and made myriad videos for people experiencing loneliness or boredom at home. User-shared videos generate parasocial attachment and virtual connectedness. However, there is limited knowledge of how creators contributed videos during disasters to provide social provisions as disaster-relief. Grounded on Weiss's loneliness theory, this work analyzed 1488 SHWM videos to examine video sharing as a pathway to social provisions. Findings suggested that skill and knowledge sharing, entertaining arts, homelife activities, live chatting, and gameplay were the most popular video styles. YouTubers utilized parasocial relationships to form a space for staying away from the disaster. SHWM YouTubers provided friend-like, mentor-like, and family-like provisions through videos in different styles. Family-like provisions led to the highest overall viewer engagement. Based on the findings, design implications for supporting viewers' mental wellbeing in disasters are discussed.

description: RX J1713.7-3946 is a unique core-collapse SNR that emits bright TeV gamma-rays and synchrotron X-rays caused by cosmic rays, in addition to interactions with interstellar gas clouds. We report here on results of ALMA $^{12}$CO($J$ = 1-0) observations toward the northwestern shell of the SNR. We newly found three molecular complexes consisting of dozens of shocked molecular cloudlets and filaments with typical radii of $\sim$0.03-0.05 pc and densities of $\sim$$10^4$ cm$^{-3}$. These cloudlets and filaments are located not only along synchrotron X-ray filaments, but also in the vicinity of X-ray hotspots with month or year-scale time variations. We argue that X-ray hotspots were generated by shock-cloudlet interactions through magnetic-field amplification up to mG. The ISM density contrast of $\sim$$10^5$, coexistence of molecular cloudlets and low-density diffuse medium of $\sim$0.1 cm$^{-3}$, is consistent with such a magnetic field amplification as well as a wind-bubble scenario. The small-scale cloud structures also affect hadronic gamma-ray spectra considering the magnetic field amplification on surface and inside clouds.

description: We investigate the interplay between spatial anisotropy and further exchange interactions in the spin-$\frac{1}{2}$ Heisenberg antiferromagnetic model on a triangular lattice. We use the Schwinger boson theory by including Gaussian fluctuations above the mean-field approach. The phase diagram exhibits a strong reduction of the long range collinear and incommensurate spirals regions with respect to the mean-field ones. This reduction is accompanied by the emergence of its short range order counterparts, leaving an ample room for $0$-flux and nematic spin liquid regions. Remarkably, within the neighborhood of the spatially isotropic line, there is a range where the spirals are so fragile that only the commensurate $120^{\circ}$ Néel ones survive. The good agreement with recent variational Monte Carlo predictions gives support to the rich phase diagram induced by spatial anisotropy.

description: Pierre Elliott Trudeau's ideas on liberal democracy and political philosophy are relevant to Canadian life. He is a modern liberal democrat with a vision of the 'Good' society - what he terms the Just Society. The values of a Just Society are numerous, but perhaps, the most important are freedom, equality, and tolerance. These values are core to his theory and are often revealed in his battle against nationalism. Trudeau is radically opposed to notions of ethnic nationalism, such as French Canadian and Aboriginal nationalism, but he supports a type of civic nationalism within a federal, pluralistic system. In his dislike for nationalism, Trudeau is similar to Lord Acton, who has had a major influence on his work. Trudeau also shows thought similar to John Locke, J.S. Mill, I. Berlin, de Tocqueville, Publius, and John Rawls.

description: One of the main drawbacks of deep Convolutional Neural Networks (DCNN) is that they lack generalization capability. In this work, we focus on the problem of heterogeneous domain generalization which aims to improve the generalization capability across different tasks, which is, how to learn a DCNN model with multiple domain data such that the trained feature extractor can be generalized to supporting recognition of novel categories in a novel target domain. To solve this problem, we propose a novel heterogeneous domain generalization method by mixing up samples across multiple source domains with two different sampling strategies. Our experimental results based on the Visual Decathlon benchmark demonstrates the effectiveness of our proposed method. The code is released in \url{https://github.com/wyf0912/MIXALL}

description: The origin of hard X-rays and gamma-rays emitted from the solar atmosphere during occulted solar flares is still debated. The hard X-ray emissions could come from flaring loop tops rising above the limb or Coronal Mass Ejections (CME) shock waves, two by-products of energetic solar storms. For the shock scenario to work, accelerated particles must be released on magnetic field lines rooted on the visible disk and precipitate. We present a new Monte Carlo code that computes particle acceleration at shocks propagating along large coronal magnetic loops. A first implementation of the model is carried out for the 2014 September 1 event and the modeled electron spectra are compared with those inferred from Fermi Gamma-ray Burst Monitor (GBM) measurements. When particle diffusion processes are invoked our model can reproduce the hard electron spectra measured by GBM nearly ten minutes after the estimated on-disk hard X-rays appear to have ceased from the flare site.

description: We study effects of Fermi surface fluctuations on a single-particle life time near the diagonal electronic nematic phase on a two-dimensional square lattice. It has been shown that there exists a quantum critical point (QCP) between the diagonal nematic and isotropic phases. We study the longitudinal fluctuations of the order parameter near the critical point, where the singular forward scattering leads to a non-Fermi liquid behavior over the whole Fermi surface except along the k_x- and k_y-directions. We will also discuss the temperature and chemical potential dependence of the single-particle decay rate.

Construction, expression and characterization of CD45-immunoglobulin fusion proteins
Creators: name: Awrey, Shannon June
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this work was to create, express, and characterize fusion proteins consisting of different alternatively spliced exons of murine CD45, a protein tyrosine phosphatase, linked to the heavy chain constant regions of murine immunoglobulin G. CD45-immunoglobulin fusion proteins were secreted as dimers in a relatively pure form using serum free media at an approximate yield of 1.5-4.5 ug / m l , depending on the isoform of CD45 and the cell line in which it was expressed. Fusion proteins secreted by Cos 7 cells had a higher apparent molecular weight by approximately 5-10 kDa than those expressed by X63-Ag8.653 or T28 cells. The interaction of CD45 with putative ligands may be mediated by specific carbohydrate residues on CD45, therefore, the carbohydrate residues expressed on CD45-immunoglobulin fusion proteins were characterized. O-glycosidase digestion and lectin analysis revealed that all fusion proteins were extensively O-glycosylated in a cell-specific manner. Neuraminidase digestion and analysis of subsequent Peanut agglutinin reactivity suggested that fusion proteins secreted by Cos 7 cells expressed more sialic acid when compared to that secreted by X63-Ag8.653 or T28 cells. Thrombin cleavage and PNGase F digestion revealed that the immunoglobulin portion was 34 kDa and the only site of N-linked carbohydrate addition. A l l fusion proteins reacted with anti-CD45 exon-specific antibodies as predicted with the exception of RA3 6B2, a B220-specific antibody that reacted with CD45RABCIg expressed by Cos 7 cells but not with that expressed by X63-Ag8.653 or T28 cells. RA3 6B2 reacted with fusion proteins containing exons A , B, and C inclusive in addition to fusion proteins containing only exon A. RA3 6B2 binding was not affected by neuraminidase treatment, but did correlate to the binding of wheat germ agglutinin. Once expressed and purified, CD45-immunoglobulin fusion proteins can be used as diagnostic tools in immunoadherence and adhesion assays in an attempt to further our understanding of T lymphocyte signalling via the identification an isoform-specific ligand(s) for murine CD45.

description: We performed 3-dimensional N-body/SPH simulations to study how mass resolution and other model parameters such as the star formation efficiency parameter, C* and the threshold density, nth affect structures of the galactic gaseous/stellar disk in a static galactic potential. We employ 10^6 - 10^7 particles to resolve a cold and dense (T < 100 K & n_H > 100 cm^{-3}) phase. We found that structures of the ISM and the distribution of young stars are sensitive to the assumed nth. High-nth models with nth = 100 cm^{-3} yield clumpy multi-phase features in the ISM. Young stars are distributed in a thin disk of which half-mass scale height is 10 - 30 pc. In low-nth models with nth = 0.1 cm^{-3}, the stellar disk is found to be several times thicker, and the gas disk appears smoother than the high-nth models. A high-resolution simulation with high-nth is necessary to reproduce the complex structure of the gas disk. The global properties of the model galaxies in low-nth models, such as star formation histories, are similar to those in the high-nth models when we tune the value of C* so that they reproduce the observed relation between surface gas density and surface star formation rate density. We however emphasize that high-nth models automatically reproduce the relation, regardless of the values of C*. The ISM structure, phase distribution, and distributions of young star forming region are quite similar between two runs with values of C* which differ by a factor of 15. We also found that the timescale of the flow from n_H ~1 cm^{-3} to n_H > 100 cm^{-3} is about 5 times as long as the local dynamical time and is independent of the value of C*. The use of a high-nth criterion for star formation in high-resolution simulations makes numerical models fairy insensitive to the modelling of star formation. (Abridged)

description: In the last decade, many researchers focused on improvement of environmental friendliness and on the principles of sustainable development, green logistics became a new field of transport research. The article presents an overview of the research in this area using as an example foreign and Russian projects. It is shown that the existing approaches, methods and instruments of «green» logistics are scattered, their use leads to making contradictory decisions that do not contribute to a systematic reduction of the harmful impact of transport on the environment. The authors proposed their approach to systematization of principles and methods of «green» logistics, which will allow creating more balanced programs to improve the environmental friendliness and efficiency of transport system.
В последнее десятилетие на транспорте утвердилось научное направление, ориентированное на повышение экологичности и основанное на принципах устойчивого развития, - «зелёная» логистика. В статье представлен обзор исследований в этой области на примере зарубежных и российских проектов. Показано, что существующие подходы, методы и инструменты «зелёной» логистики носят разрозненный характер, их использование приводит к принятию противоречивых решений, не способствующих планомерному снижению вредного воздействия транспорта на окружающую среду. Авторами предложен свой подход к систематизации принципов и методов «зелёной» логистики, который позволит формировать более сбалансированные программы повышения экологичности и эффективности функционирования транспортных систем.

description: We investigate the chemical reactivity of molecular populations confined inside a nanofluidic Fabry-P{é}rot cavity. Due to strong light-matter interactions developing between a resonant electromagnetic cavity-mode and the electric dipole moment of the confined molecules, a polariton is formed. The former gets dressed by environmental vibrational and rotational degrees of freedom of the solvent. We call the resulting polariton dressed by its cloud of environmental excitation a ''reacton'', since it further undergoes chemical reactions. We characterize how the reacton formation modifies the kinetics of a photoisomerization chemical reaction involving an elementary charge-transfer process. We show that the reaction driving-force and reorganization energy are both modulated optically by the reactant concentration, the vacuum Rabi splitting and the de-tuning between the Fabry-P{é}rot cavity frequency and targeted electronic transition. Finally, we compute the ultrafast picosecond dynamics of the whole photochemical reaction. We predict that despite optical cavity losses and solvent-mediated non-radiative relaxation, measurable signatures of the reacton formation can be found in state-of-the-art pump-probe experiments.
