description: We probe the evolution of globular clusters that could form in giant molecular clouds within high-redshift galaxies. Numerical simulations demonstrate that the large and dense enough gas clouds assemble naturally in current hierarchical models of galaxy formation. These clouds are enriched with heavy elements from earlier stars and could produce star clusters in a similar way to nearby molecular clouds. The masses and sizes of the model clusters are in excellent agreement with the observations of young massive clusters. Do these model clusters evolve into globular clusters that we see in our and external galaxies? In order to study their dynamical evolution, we calculate the orbits of model clusters using the outputs of the cosmological simulation of a Milky Way-sized galaxy. We find that at present the orbits are isotropic in the inner 50 kpc of the Galaxy and preferentially radial at larger distances. All clusters located outside 10 kpc from the center formed in the now-disrupted satellite galaxies. The spatial distribution of model clusters is spheroidal, with a power-law density profile consistent with observations. The combination of two-body scattering, tidal shocks, and stellar evolution results in the evolution of the cluster mass function from an initial power law to the observed log-normal distribution.

description: We extend the public CppTransport code to calculate the statistical properties of fluctuations in multiple-field inflationary models with curved field space. Our implementation accounts for all physical effects at tree-level in the 'in-in' diagrammatic expansion. This includes particle production due to time-varying masses, but excludes scenarios where the curvature perturbation is generated by averaging over the decay of more than one particle. We test our implementation by comparing results in Cartesian and polar field-space coordinates, showing excellent numerical agreement and only minor degradation in compute time. We compare our results with the PyTransport 2.0 code, which uses the same computational approach but a different numerical implementation, finding good agreement. Finally, we use our tools to study a class of gelaton-like models which could produce an enhanced non-Gaussian signal on equilateral configurations of the Fourier bispectrum. We show this is difficult to achieve using hyperbolic field-space manifolds and simple inflationary potentials.

description: Egypt is considered a higher wheat importer in the world, and given the reality that futures prices lead spot prices that makes the Egyptian prices vulnerable to future wheat markets. This study assesses the relationship between Egyptian flour prices and future wheat prices associated with Paris (MATIF) and USA (CBOT). Markov switching-vector error correction methods are used to estimate two regimes by splitting the sample by high and low volatility regimes. This study also examines the dynamic conditional correlation using Asymmetric-Dynamic Conditional Correlation with Multivariate Generalized Autoregressive Conditional Heteroscedasticity (DCC-GARCH). Results suggest a high volatility regime observes especially during the extreme market events; in the time of the food crisis 2007/2008 and 2010 as well as after two revaluations in Egypt in 2011 and 2013 and during the economic reforms in 2016, mainly in the range from 0 to 0.4 before crisis, while the fluctuations are higher in the time of food crisis, revolutions and economic reform that in the range from -0.2 to 0.8. This implies that the negative impact of the economic and political crisis on the consumer prices. The results provide evidence of symmetric volatility spillovers from future markets to Egyptian wheat market. Results from impulse response functions indicate that shock by 1% in the future markets will lead to positive shock in the flour spot market in Egypt.

description: The purpose of this study is to investigate consumer attitudes and behaviors towards table eggs in order to analyse the consumer profiles. It is aimed to create possible linkages between the obtained consumer groups and table eggs consumption frequencies. The data employed in this paper were taken from a face to face cross-sectional survey conducted with 547 individuals in the major cities (İstanbul, Ankara, İzmir, Trabzon, Adana, Van, and Gaziantep) of the seven regions of Turkey during the period February-May 2017. The answers of the survey questions were designed based on Likert-type scale in order to make the analysis. The data were analysed using descriptive statistics, Principal Component Analyse (PCA) with Varimax rotation and ordered probit regression methods by SPSS© 21 and STATA© 13 software’s. Results show that nutrition, taste, health and freshness are the main factors effecting consumers’ table egg consumption preferences. To detect the perceived differences among the consumers by creating clusters a Principal Component Analyse was performed and 5 consumer groups (suspicious and eco-sensitive, marketing consciousness, enthusiasts, food security sensitive and reluctant) with different characteristics were obtained on the preference for table eggs (KMO: .754; Bartlett's Test Sig: 0.000). Later these 5 egg consumer groups were associated with consumption frequencies by the ordered probit regression model. The analysis show that three of these consumer groups were found to have a significant relationship with the consumption frequencies. The marginal impacts were also calculated to show consumption position and structure of these consumer groups for each group of consumption frequency.
Unsteady Outflow Models for Cosmological Gamma-Ray Bursts

Year: 1994

description: The 'event' that triggers a gamma ray burst cannot last for more than a few seconds. This is, however, long compared with the dynamical timescale of a compact stellar-mass object ($\sim 10^{-3}$ seconds). Energy is assumed to be released as an outflow with high mean lorentz factor $Γ$. But a compact stellar-mass collapse or merger is, realistically, likely to generate a mass (or energy) flux that is unsteady on some timescales in the range $10^{-3}$ - 10 seconds. If $Γ$ fluctuates by a factor of $\sim 2$ around its mean value, relative motions within the outflowing material will themselves (in the comoving frame) be relativistic, and can give rise to internal shocks. For $Γ\sim 10^2$, the resultant dissipation occurs outside the 'photosphere' and can convert a substantial fraction of the overall outflow energy into non-thermal radiation. This suggests a mechanism for cosmological bursts that demands less extreme assumptions (in respect of $Γ$-values, freedom from baryonic contamination, etc) than earlier proposals.

description: We derive the macroscopic Fourier's Law of heat conduction from the exact gain-loss time convolutionless quantum master equation under three assumptions for the interaction kernel. To second order in the interaction, we show that the first two assumptions are natural results of the long time limit. The third assumption can be satisfied by a family of interactions consisting an exchange effect. The pure exchange model directly leads to energy diffusion in a weakly coupled spin-1/2 chain.

These planets will collide in $\sim 10^4$ years if their orbits are coplanar. Some fragments of debris lose their angular momentum in the collision and fall onto the neutron star, producing a SGR. The initial accretion of matter left by the collision with essentially no angular momentum may produce a superburst like that of March 5, 1979, while debris fragments which later lose their angular momentum produce an irregular pattern of smaller bursts.

The development of novel siRNA nanoparticles for delivery to pulmonary epithelial cells
Creators: name: Hibbitts, Alan J.
Publisher: name: Royal College of Surgeons in Ireland
Year: 2019
Subjects: Uncategorized

description: Local delivery of short-interfering RNA (siRNA) to the lungs represents a promising means of treating a range of pulmonary conditions such as acute lung injury (ALI) and chronic obstructive pulmonary disorder (COPD). However, effective pulmonary delivery of siRNA remains hampered by a range of host defence mechanisms. Furthermore, pharmaceutical issues that are currently impeding pulmonary siRNA therapy include cytotoxicity, inefficient rates of delivery and low levels of post-delivery siRNA stability. One strategy to overcome these issues involves encapsulation of siRNA in nanoparticles. These can potentially facilitate intracellular delivery to target cells, overcome the mucus barrier and ensure stable delivery. Successful siRNA mediated therapy for respiratory disease is also dependent, however, on integration with an effective means of delivery to the appropriate area of the lungs. Herein, we have developed a range of gene delivery vectors (GDVs) suitable for inhalation for enhanced siRNA delivery to lung epithelial cells. A range of novel Poly(ethyleneimine)-Poly(ethylene) glycol (PEI-PEG) co-polymers, aminemodified cyclodextrin (SC12CD) and PEGylated peptidomimetic constructs (AOC95/99) were combined with siRNA to form siRNA nanoparticles. These were then characterised by developing high throughput, multi-parameter screening methods. These performed a detailed examination of siRNA uptake efficiency and cytotoxicity in Calu-3 bronchial epithelial cells. In vitro siRNA knockdown following siRNA nanoparticle delivery was assessed in undifferentiated and fully differentiated, mucus-producing Calu-3 cell culture. The effect of nébulisation on siRNA nanoparticle transfection efficiency was determined using PEILPEG(IOkDa) in an integrated in vitro device-cell culture model. Following this, the ability of PEI-LPEG(IOkDa) IL-8- siRNA nanoparticles to modulate IL-8 in vitro and in vivo were assessed following the establishment of an LPS-stimulated rat model of pulmonary inflammation. Results of these experiments found that PEGylation of PEI, particularly 10kDa linear PEG, resulted in significant (pin vivostudies, reductions in IL-8 gene expression were observed in lung epithelial cells but were lost at a protein level. Early indications were of PEGylation being associated with pro-inflammatory effects, however there was no significant increase compared to unmodified PEI and positive controls.

This general effect, not specific to hydrogen-bonding solvents, is controlled by electroneutrality condition, dipolar interactions and dielectric+ionic screening. As expected, all numerical theories recover the well-known analytical expressions established 40 years ago.

description: The interaction of matter with gravity in two dimensional spacetimes can be supplemented with a geometrical force analogous to a Lorentz force produced on a surface by a constant perpendicular magnetic field. In the special case of constant curvature, the relevant symmetry does not lead to the de Sitter or the Poincaré algebra but to an extension of them by a central element. This richer structure suggests to construct a gauge theory of 2-D gravity that reproduces the Jackiw-Teitelboim model and the string inspired model. Moreover matter can be coupled in a gauge invariant fashion. Classical and quantized results are discussed. Based on a talk given at the XXIIIth International Conference on Differential Geometric Methods in Theoretical Physics. Ixtapa, Mexico. September 1993.

description: We discuss the two-particle irreducible (2PI) effective action for the SYK model and for tensor field theories. For the SYK model the 2PI effective action reproduces the bilocal reformulation of the model without using replicas. In general tensor field theories the 2PI formalism is the only way to obtain a bilocal reformulation of the theory, and as such is a precious instrument for the identification of soft modes and for possible holographic interpretations. We compute the 2PI action for several models, and push it up to fourth order in the $1/N$ expansion for the model proposed by Witten in arXiv:1610.09758, uncovering a one-loop structure in terms of an auxiliary bilocal action.

Medical Students Workload: Implication to the European Credit Transfer and Accumulation System in Integrated PBL Curriculum.

description: Student workload (SWL) is one of the main elements of curriculum design, and its measurement is problematic especially in an integrated problem-based-learning (PBL) environment. It is the foundation of determination of the European Credit Transfer and Accumulation System (ECTS) units which are awarded upon students’ achievement. As ECTS depends on the notional, and not on the contact SWL, it has been more flexible for meeting the needs of the modern innovative educational trends. The lack of suitable credit system in our medical PBL institution was the drive for the change project. The aim of the project was to identify the nature and amount of students’ independent learning activities in order to assign the ECTS units to our medical PBL program components. HSE OD change model was used, where focus group interviews and log diaries were employed. Based on that, calculations were then used for allocating ECTS to the studied units. The response evaluation model and thematic description approach were used for data collection and data analysis respectively. The broad variations of the independent studying activities have confirmed the extra work activities in an integrated PBL programs. The measured notional SWL was about 55 and 58 hrs./week, which equates 29 and 31 ECTS/semester for years two and three respectively. In conclusion, measuring SWL is an indispensable need in PBL programs for evading the associated overload, and improving quality of learning. Assigning ECTS improves program quality assurance, and has educational, curricular and organizational impacts which should be regularity monitored and evaluated.
The Impact of Surgery on Balance, Gait, Upper limb Dexterity and Dizziness in Patients with Posterior Fossa Tumours

description: Introduction: Tumours of the posterior fossa of the cranium are associated with significant impairments, morbidity and mortality. Limited evidence is available in the adult population, of the potential impact a surgical intervention can have on function, in this tumour type. The rehabilitation practices utilised to treat the associated impairments have also received limited investigation. Aims/Objectives: The primary aim of this research study was to characterise the impact of surgery on balance, gait, upper limb dexterity and dizziness in patients with posterior fossa tumours. Secondary aims of the study were to profile the demographic and tumour characteristics of the study participants. Methods: This was a prospective cohort study, which recruited thirteen participants over an eighteen month period. A comprehensive testing battery was completed over four time-points, of six months duration, to categorise the impact of surgery. A systematic review of rehabilitation practices in the management of impairments, associated with posterior fossa tumours, was also completed. Results: Thirteen participants, of mean age 48.8 ± 15.7, were recruited to the study. An improvement in the primary outcome, equilibrium and balance, was observed post-operatively, while surgical impact on gait speed, upper limb dexterity and dizziness resulted in negative consequences. Significant morbidity and mortality was associated with surgery in this population, impacting on data collection and analysis. Conclusions and Implications: Surgical intervention for the presence of a tumour in the posterior fossa, resulted in a decrease in gait speed and upper limb dexterity, an increase in dizziness and improvement in balance, post-operatively. The most frequently occurring tumour type was metastases, indicating the high risk of mortality associated with a tumour of this region of the brain. The testing battery used in this research project provides the foundation for comprehensive assessment and treatment of this population of patients, in future care.

Fractional Programming for Communication Systems--Part II: Uplink Scheduling via Matching

Year: 2018
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: This two-part paper develops novel methodologies for using fractional programming (FP) techniques to design and optimize communication systems. Part I of this paper proposes a new quadratic transform for FP and treats its application for continuous optimization problems. In this Part II of the paper, we study discrete problems, such as those involving user scheduling, which are considerably more difficult to solve. Unlike the continuous problems, discrete or mixed discrete-continuous problems normally cannot be recast as convex problems. In contrast to the common heuristic of relaxing the discrete variables, this work reformulates the original problem in an FP form amenable to distributed combinatorial optimization. The paper illustrates this methodology by tackling the important and challenging problem of uplink coordinated multi-cell user scheduling in wireless cellular systems. Uplink scheduling is more challenging than downlink scheduling, because uplink user scheduling decisions significantly affect the interference pattern in nearby cells. Further, the discrete scheduling variable needs to be optimized jointly with continuous variables such as transmit power levels and beamformers. The main idea of the proposed FP approach is to decouple the interaction among the interfering links, thereby permitting a distributed and joint optimization of the discrete and continuous variables with provable convergence. The paper shows that the well-known weighted minimum mean-square-error (WMMSE) algorithm can also be derived from a particular use of FP; but our proposed FP-based method significantly outperforms WMMSE when discrete user scheduling variables are involved, both in term of run-time efficiency and optimizing results.

description: We consider in this paper the quantum limits for measurements on macroscopic bodies which are obtained in a novel way employing the concept of decoherence coming from an analysis of the quantum mechanics of dissipative systems. Two cases are analysed, the free mass and the harmonic oscillator, and for both systems we compare our approach with previous treatments of such limits.

title: From Margins to Centre: The Experiences of Black Free School Proposers

description: This is a qualitative piece of research focused on the experiences of African Caribbean education practitioners/grassroots organisations in applying to open free schools in London during the period 2010-2014. Although free schools were launched under the auspices of engaging local communities in delivering educational services, the evidence suggests that the free school landscape is dominated by already established, powerful organisations. Using a Critical Race Theory framework, the research interrogates how race and racism operate in the free school application and approval process which is largely concealed from the public. This thesis argues that in spite of the colourblind discourse surrounding free schools, both overt and covert racism are factors in the how free school applications are being assessed by the government. The research challenges the exclusion of many black grassroots practitioners/organisations from opening free schools by identifying several assets they possess which make them well placed to deliver educational services.

description: A hybrid (hydrodynamics + hadronic transport) theoretical framework is assembled to model the bulk dynamics of relativistic heavy-ion collisions at energies accessible in the Beam Energy Scan (BES) program at the Relativistic Heavy-Ion Collider (RHIC) and the NA61/SHINE experiment at CERN. The system's energy-momentum tensor and net baryon current are evolved according to relativistic hydrodynamics with finite shear viscosity and non-zero net baryon diffusion. Our hydrodynamic description is matched to a hadronic transport model in the dilute region. With this fully integrated theoretical framework, we present a pilot study of the hadronic chemistry, particle spectra, and anisotropic flow. Phenomenological effects of a non-zero net-baryon current and its diffusion on hadronic observables are presented for the first time. The importance of the hadronic transport phase is also investigated.

description: Chemical investigation on the cultures of the fungus Cordyceps spp., a strain from cell fusion between Cordyceps militaris and Cordyceps cicadae, resulted in the isolation of 13 compounds including 2 new ones named 2-(5-(3-oxobutyl) furan-2-yl) acetic acid (1) and cordycepone (2). Their structures were elucidated from the analysis of 1D/2D NMR and CD data. Among them, compounds 1, 7–9, at a concentration of 50 μg/ml, showed weak inhibitory activity against AChE. Moreover, compounds 6, 9, and 11 showed moderate inhibitory activity against the nematode Panagrellus redivivus with mortality ratio of 79.0, 71.7, and 72.3% at 2.5 mg/ml, respectively.

description: In this talk we survey the SSC signals and backgrounds for the physics of electroweak symmetry breaking. We study the process $pp \rightarrow WWX$ and compute the rate for the ``gold-plated'' signals $W^\pm \rightarrow \ell^\pm ν$ and $Z \rightarrow \ell^+\ell^-$ $(\ell = e,μ)$ for a wide variety of models. We use a forward jet tag and central jet veto to suppress the standard-model backgrounds. In this way we estimate the SSC sensitivity to the physics of electroweak symmetry breaking.

Fractional Programming for Communication Systems--Part I: Power Control and Beamforming

description: This two-part paper explores the use of FP in the design and optimization of communication systems. Part I of this paper focuses on FP theory and on solving continuous problems. The main theoretical contribution is a novel quadratic transform technique for tackling the multiple-ratio concave-convex FP problem--in contrast to conventional FP techniques that mostly can only deal with the single-ratio or the max-min-ratio case. Multiple-ratio FP problems are important for the optimization of communication networks, because system-level design often involves multiple signal-to-interference-plus-noise ratio terms. This paper considers the applications of FP to solving continuous problems in communication system design, particularly for power control, beamforming, and energy efficiency maximization. These application cases illustrate that the proposed quadratic transform can greatly facilitate the optimization involving ratios by recasting the original nonconvex problem as a sequence of convex problems. This FP-based problem reformulation gives rise to an efficient iterative optimization algorithm with provable convergence to a stationary point. The paper further demonstrates close connections between the proposed FP approach and other well-known algorithms in the literature, such as the fixed-point iteration and the weighted minimum mean-square-error beamforming. The optimization of discrete problems is discussed in Part II of this paper.

LOCKDOWN

description: The national lockdown initiated in March 2020, with barely 600 cases in India, raised concerns over its
 political and economic costs. State Governments were, understandably, hesitant in imposing another
 lockdown in 2021 even amidst a surge. The draconian lockdown and the “junta curfew” last year was
 declared a failed policy instrument in curbing the virus. The State machinery had to move towards ideas
 of limited movements, micro containment zones and relaxed restrictions before nally resorting to a
 lockdown. The virulence and unpredictability of the disease have forced Governments to innovate
 pandemic management processes and protocols. A lockdown that stalls movement and inhibits human interaction is only a band-aid approach to a larger
 systemic failure. The lives lost for the lack of Oxygen, hospital beds, essential medicines and money are
 a constant reminder of the gross neglect of healthcare infrastructure and the failure of governance
 during a crisis. Governments can no longer continue with piecemeal enhancements in limiting the
 pandemic and improving healthcare. It is important to understand that locking down cities not only
 imposes huge burdens on the revenue side, but also subdues consumption and distorts incomes,
 especially for the poor.
Observational Constraints on Theories with a Blue Spectrum of Tensor Modes

description: Motivated by the string gas cosmological model, which predicts a blue tilt of the primordial gravitational wave spectrum, we examine the constraints imposed by current and planned observations on a blue tilted tensor spectrum. Starting from an expression for the primordial gravitational wave spectrum normalized using cosmic microwave background observations, pulsar timing, direct detection and nucleosynthesis bounds are examined. If we assume a tensor to scalar ratio on scales of the CMB which equals the current observational upper bound, we obtain from these current observations constraints on the tensor spectral index of $n_{T} \lesssim 0.79$, $n_{T} \lesssim 0.53$, and $n_{T} \lesssim 0.15$ respectively.

The time-scales of major mergers from simulations of isolated binary galaxy collisions

description: A six-dimensional parameter space based on high-resolution numerical simulations of isolated binary galaxy collisions has been constructed to investigate the dynamical friction timescales, $τ_{\rm mer}$, for major mergers. Our experiments follow the gravitational encounters between $\sim 600$ pairs of similarly massive late- and early-type galaxies with orbital parameters compliant to the predictions of the LambdaCDM cosmology. We analyze the performance of different schemes for tracking the secular evolution of mergers, finding that the product of the intergalactic distance and velocity is best suited to identify the time of coalescence. In contrast, a widely used merger time estimator such as the exhaustion of the orbital spin is shown to systematically underpredict $τ_ {\rm mer}$, resulting in relative errors that can reach 60% for nearly radial encounters. Regarding the internal spins of the progenitors, we find that they can lead to total variations in the merger times above 30% in highly circular encounters, whereas only that of the principal halo is capable of modulating the strength of the interaction prevailing throughout a merger. The comparison of our simulated merger times with predictions from different variants of a well-known fitting formula has revealed an only partially satisfactory agreement, which has led us to recalculate the values of the coefficients of these expressions to obtain relations that fit perfectly major mergers. The observed biases between data and predictions, that do not only apply to the present work, are inconsistent with expectations from differences in the degree of idealization of the collisions, their metric, spin-related biases, or the simulation set-up. This hints to a certain lack of accuracy of the dynamical friction modelling, arising perhaps from a still not quite complete identification of the parameters governing orbital decay.
