description: We study current-driven magnetization switching in nanofabricated magnetic trilayers, varying the magnetoresistance in three different ways. First, we insert a strongly spin-scattering layer between the magnetic trilayer and one of the electrodes, giving increased magnetoresistance. Second, we insert a spacer with a short spin-diffusion length between the magnetic layers, decreasing the magnetoresistance. Third, we vary the angle between layer magnetizations. In all cases, we find an approximately linear dependence between magnetoresistance and inverse switching current. We give a qualitative explanation for the observed behaviors, and suggest some ways in which the switching currents may be reduced.

description: estimate the causal effects of demand shocks, stemming from government procurement, on the growth of small firms in Ecuador. I assemble a unique dataset using several new administrative sources and, as identification strategy, exploit a governmental procurement process that allocates public contracts through a randomised contest. I find a positive and significant effect of demand shocks on firm growth. On average, an increase in demand of 10 per cent will increase wage expenses and fixed assets by approximately 5 per cent during the year of the shock. I also find no evidence of spillover effects from demand shocks on sales to the public or private sector. Finally, as in other studies, I show that demand positively impacts firm growth but, contrary to other findings, this effect is temporary and only observed during the year of the shock.

description: We address the effect of band filling on the effective electron mass $m^*$ and the superconducting critical temperature $T_c$ in a electron-phonon system. We compare the vertex corrected theory with the non-crossing approximation of the Holstein model within a local approximation. We identify two regions of the electron density where $m^*$ and $T_c$ are enhanced or decreased by the inclusion of the vertex diagrams. We show that the crossover between the enhancement at low density and the decrease towards half filling is almost independent of the microscopic electron-phonon parameters. These different behaviors are explained in terms of the net sign of the vertex diagrams which is positive at low densities and negative close to half filling. Predictions of the present theory for doped MgB$_2$, which is argued to be in the low density regime, are discussed.

description: We study the impact of a finite magnetic field on the deconfinement phase transition for heavy quarks by computing the fluctuations of the Polyakov loops. It is demonstrated that the explicit Z(3) breaking field increases with the magnetic field, leading to a decrease in the (pseudo) critical temperatures and a shrinking first-order region in the phase diagram. Phenomenological equations that capture the behaviors of the Z(3) breaking field at strong and weak magnetic fields for massive and massless quarks are given. Lastly, we explore the case of dynamical light quarks and demonstrate how an improved constituent quark mass function can enforce the correct magnetic field dependence of the deconfinement temperature in an effective model, as observed in Lattice QCD calculations.

description: Assuming the two diquark structure for the pentaquark state as advocated in the Jaffe-Wilczek model, there exist exotic parity-even anti-sextet and parity-odd triplet heavy pentaquark baryons. The theoretical estimate of charmed and bottom pentaquark masses is quite controversial and it is not clear whether the ground-state heavy pentaquark lies above or below the strong-decay threshold. We study the weak transitions of heavy pentaquark states using the light-front quark model. In the heavy quark limit, heavy-to-heavy pentaquark transition form factors can be expressed in terms of three Isgur-Wise functions: two of them are found to be normalized to unity at zero recoil, while the third one is equal to 1/2 at the maximum momentum transfer, in accordance with the prediction of the large-Nc approach or the quark model. Therefore, the light-front model calculations are consistent with the requirement of heavy quark symmetry. Numerical results for form factors and Isgur-Wise functions are presented. Decay rates of the weak decays Theta_b+ to Theta_c0 pi+ (rho+), Theta_c0 to Theta+ pi- (rho-), Sigma'_{5b}+ to Sigma'_{5c}0 pi+ (rho+) and Sigma'_{5c}0 to N_8+ pi- (rho-) with Theta_Q, Sigma'_{5Q} and N_8 being the heavy anti-sextet, heavy triplet and light octet pentaquarks, respectively, are obtained. For weakly decaying Theta_b+ and Theta_c0, the branching ratios of Theta_b+ to Theta_c0 pi+, Theta_c0 to Theta+ pi- are estimated to be at the level of 10^{-3} and a few percents, respectively.

description: The Indonesian Government launched a for-poor students cash transfer program (Bantuan Siswa Miskin, BSM) to aid poor students in attaining goods and services that would improve school attendance. Recipients should spend the cash to support school attendance, however, the government does not have any control on how households spend the transfer. Using the Indonesian Family Life Survey, we evaluate whether the BSM program affects education spending. To deal with the issues of endogeneity and unobserved heterogeneity, we use the BSM eligibility criteria set by the government as instrumental variables and the first-difference estimation strategy. We find that BSM has a significant and positive effect on education spending. This study provides evidence that households use the transfer according to the intended purpose even though there is no formal mechanism to ensure households’ compliance.

description: The Belarusian economy is in a state of balance since 2016: trade deficit and gross foreign debt were reduced, the local currency strengthened. The problem is in resumption of economic growth, while avoiding trade deficit. The role of structural policy is to control the rate of growth of specific industries. Those industries that provide trade surplus should grow faster. Government was stimulated both investment and consumer demand in the period from 2006 to 2014. As a result, GDP growth reached 5-12%, but subsequently the gross foreign debt exceeded 75% of GDP. We have found that economic growth stimulation through quantitative easing in a small open economy usually leads to imbalances. Furthermore, imbalances reach critical levels if exports declining. In 2016 the situation with exports was extremely unfavorable for Belarus. Therefore, if government could not abandon stimulation entirely, it should still apply it selectively, in order to avoid imbalances. For this purpose, we propose to differentiate the industries in their contribution to the trade balance. We offer a tool for assessing the contribution of each sector of economy (industry, or a product) to the trade balance. Baseline data are presented in the Input-Output tables, and the methodology is based on the Trade in Value Added (TiVA) indicators. Particularly, we line up the aggregate value chains for each final product, distinguishing foreign and domestic value added in gross exports and final demand for each industry. The estimates of the Belarusian economy made it possible to divide the industries into three groups, according to their contribution to the trade balance: Group 1: Products that contribute trade surplus. Domestic value added embodied in these products exceeds domestic final demand, taking into account the intermediate and final imports. This group includes: petroleum products, chemicals, transport services, business services (including software development). Group 2: Products creating trade deficit. Final demand for these products exceeds domestic value added – they are construction services, as well as manufacturing products: machinery and equipment, electronics and vehicles. Group 3: Relatively neutral to the trade balance products, which include garment, wood, retailing, and some others. For instance, it was found that the construction industry creates $3,5-4,5 billion of net imports, while total gross imports equals $44-48 billion in 2012 – 2014. In this period, petroleum products contributed approximately the same amount (if take into consideration export margins) to the domestic value added embodied in gross exports. In 2016 exports of petroleum products declined on a half. The volume of construction works was also halved, that allowed avoiding trade imbalance.

description: We compare the statistical thermodynamics of hadron resonance gas with recent LGT results at finite chemical potential. We argue that for $T\leq T_c$ the equation of state derived from Monte--Carlo simulations of two quark--flavor QCD at finite chemical potential is consistent with that of a hadron resonance gas when applying the same set of approximations as used in LGT calculations. We indicate the relation of chemical freezeout conditions obtained from a detailed analysis of particle production in heavy ion collisions with the critical conditions required for deconfinement. We argue that the position of a hadron--quark gluon boundary line in temperature chemical potential plane can be determined in terms of the resonance gas model by the condition of fixed energy density.

description: At present time there is no facility that normally exists without a marketing division. Relevance of the marketing even rises day by day. Marketing budgets tend to the substantial growth over the last 15 years. Issues related to the grounding of the cost escalation remain open. This situation creates tensions in relations between financial and marketing departments. To improve the marketing activity and to increase the marketability facilities need regularly measure the performance of the marketing.

description: In this paper, I present my approach to the Riemann Hypothesis, which potentially provides a proof of it.

I start by simplifying the equality Zeta(s)=0 by expressing |Zeta(s)|^2=0 as Re(Zeta(s))^2 + Im(Zeta(s))^2 = 0, expressed with cosine and sine functions, then I use trigonometric identities to further break down the sum into a sum of squares purely relying on Re(s) and a double sum relying on both Re(s) and Im(s).

Using the bounded nature of cosine, I reformulate the equality as problem of quadratic equations, to get rid of the dependence on Im(s),

I then consider Re(s) as a map a[n] (n being the number of terms in Zeta(s)), rather than a fixed value (since we deal with infinity),

It has already been proved that for all the nontrivial zeros, their real part is in ]0,1[,

So, I then use integrals and asymptotic analysis to observe three cases of asymptotic behaviours:

when a[n] converges to a real number in ]0,1/2[

when a[n] converges to a real number in ]1/2,1[

when a[n] converges to 1/2 (where we distinguish some more cases)

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.

description: Decision-making structures may be different across polygynous and monogamous households, leading to different economic outcomes and requiring different targeting of anti-poverty programmes. We study efficiency in semi-nomadic pastoralist households in Northern Senegal with lab-in-the-field games. We find that monogamous and polygynous families are equally productively inefficient overall. However, average contributions at the household level mask differences across dyads. Junior wives receive less but give more to their husbands than senior wives, leaving junior wives worse off than other household members.

description: The frequent emergence of diseases with the potential to become threats at local and global scales, such as influenza A(H1N1), SARS, MERS, and recently COVID-19 disease, makes it crucial to keep designing models of disease propagation and strategies to prevent or mitigate their effects in populations. Since isolated systems are exceptionally rare to find in any context, especially in human contact networks, here we examine the susceptible-infected-recovered model of disease spreading in a multiplex network formed by two distinct networks or layers, interconnected through a fraction $q$ of shared individuals (overlap). We model the interactions through weighted networks, because person-to-person interactions are diverse (or disordered); weights represent the contact times of the interactions. Using branching theory supported by simulations, we analyze a social distancing strategy that reduces the average contact time in both layers, where the intensity of the distancing is related to the topology of the layers. We find that the critical values of the distancing intensities, above which an epidemic can be prevented, increase with the overlap $q$. Also we study the effect of the social distancing on the mutual giant component of susceptible individuals, which is crucial to keep the functionality of the system. In addition, we find that for relatively small values of the overlap $q$, social distancing policies might not be needed at all to maintain the functionality of the system.

description: There is no economic growth and development where there is no clear economic policy and development strategy, that is where there are no defined priorities, nor mechanisms for a strong and systematic support to the domestic economy. The author of this study advises economic policy makers to forget the mantras of neoliberal policies that previous governments used as an excuse not to take anything and to resolutely turn their own economic development and building a strong industrial sector. That would be a shortcut to rapid economic development and bridging the decades of stalemate and stagnation. Serbia does not lack resourcefulness, but quality state apparatus, as well as guidance and assistance in the way that countries that have successfully developed did. The greatest sin of our economic policy in the last quarter of a century is a tragic neglect of industry, especially manufacturing, or as a result of all this, and the emergence of a deep ravine between production and consumption, and totally neglecting technological development. Therefore, we are firm in the belief that, in the case of seriously disturbed the economic structure of production at the expense of our future development must rely on priorities, among which would be the development of the manufacturing sector of the economy, and within it of agriculture and food industry, where our chances are objective and greatest.

That implies that an organization that tends to be successful encourages the need for changes, it motivates employees to initiate changes and be active members of the process development and organizational culture. The problem is observed through strategic surprises and possible discontinuities when considering strategic complexity as a reason for a management system to exist and function. To establish a successful management system that drives organization development towards success, the management needs to understand current business trends and set a motivating climate and culture in order to motivate all level personnel to contribute towards success. A quality system of progressive management covers more than the usual processes, initiatives for improvement and projects or documented procedures.

description: France is one of the largest economies of the world and one of the most influential countries of the EU, and its centuries-old friendship with Serbia and a strategic position in the Western Balkans and the complementarity of economies represent a good basis for the development of bilateral economic relations. However, despite the great potential for cooperation, mutual cooperation results to date are not at a high level. One of the reasons may well be just the language barrier and the lack of knowledge of French market culture. The aim of this paper is to present forms of economic cooperation between Serbia and France, to emphasize the importance of the knowledge of French language and intercultural competence as a prerequisite for cooperation, at least in the initial marketing terms. In this paper, we will give a brief historical overview of the French economic relations, and by employing a complementary analysis we will present the mutual trade between the two countries, and we will as well point out the importance of knowing the French language and French culture to the employees who have plans for successful cooperation with French partners.
title: Systematic Mid-IR And VUV Studies Of Electron Irradiated CO2:NH3 Interstellar Ice Analogues
Creators: name: James, Rachel Louise
Publisher: name: The Open University
Year: 2020

description: Over 200 molecules have been detected in the interstellar medium (ISM) but the formation pathways for most of these molecules remains elusive. It is now believed that a major route of molecular synthesis lies within the processing of interstellar ices formed on microscopic dust grains created in the cycle of star birth and death. However, despite decades of experimental research on molecular synthesis in ice films, the lack of a systematic approach to ISM analogue experiments means that there is still no comprehensive understanding of the influence of discrete experimental parameters on the synthesis of any molecular system under ISM conditions.

 To demonstrate the advantages of performing a systematic study, this thesis presents a comprehensive analysis of thermal and electron processing of CO2:NH3 binary mixtures as a function of mixing ratio. A combination of mid-IR and VUV spectroscopy is used to identify chemical products and explore the morphology within the ice mixture demonstrating the advantages of the complementarity of the two spectroscopic methods. Mid-IR spectroscopy of the thermal processing of CO2:NH3 mixtures revealed that the ice structure is ratio dependent and that products formed by electron processing of such ices is dependent on the initial ratio of the ice. VUV spectroscopy revealed a thermal reaction which is not observed from the mid-IR spectroscopic studies and allowed new products to be identified.

 This thesis therefore establishes the need to adopt a more systematic approach to ISM analogue experiments. Such comprehensive and coherent experimental data will improve the interpretation of the next generation of astrochemical observations whilst simultaneously allowing more accurate models of molecular synthesis in the ISM to be developed which in turn allows for a better understanding of processes involved in star and planet formation.

For small values of the Coulomb parameter clear signatures of a Slater insulator expected from a weak-coupling theory are found, while the strongly correlated system can be well described in terms of a Mott-Heisenberg picture. However, in contrast to the paramagnet, we do not find any evidence for a transition between these two limiting cases but rather a smooth crossover as a function of the Coulomb interaction.

description: Wireless sensor networks (WSNs) have been vastly employed in the collection and transmission of data via wireless networks. This type of network is nowadays used in many applications for surveillance activities in various environments due to its low cost and easy communications. In these networks, the sensors use a limited power source which after its depletion, since it is non-renewable, network lifetime ends. Due to the weaknesses in sensor nodes, they are vulnerable to many threats. One notable attack threating WSN is Denial of Sleep (DoS). DoS attacks denotes the loss of energy in these sensors by keeping the nodes from going into sleep and energy-saving mode. In this paper, the Abnormal Sensor Detection Accuracy (ASDA-RSA) method is utilised to counteract DoS attacks to reducing the amount of energy consumed. The ASDA-RSA schema in this paper consists of two phases to enhancement security in the WSNs. In the first phase, a clustering approach based on energy and distance is used to select the proper cluster head and in the second phase, the RSA cryptography algorithm and interlock protocol are used here along with an authentication method, to prevent DoS attacks. Moreover, ASDA-RSA method is evaluated here via extensive simulations carried out in NS-2. The simulation results indicate that the WSN network performance metrics are improved in terms of average throughput, Packet Delivery Ratio (PDR), network lifetime, detection ratio, and average residual energy.

description: This study deals with the corporate strategy of the commercial banks in Macedonia and their business models, particularly emphasizing on the bank’s structure and performance. For this purpose cluster analysis of 14 banks is conducted in order to identify the existing matrix of bank business models and to consider the existence and determination of strategic groups in the Macedonian banking system clusters. The results are leading to clear distinction between two bank clusters: high performance group and low performance group of commercial banks. In addition to the analysis the possible strategic adjustments are discussed in the context of the financial development of banking in Macedonia and the financial globalization. The paper may be useful for the corporate management of the banks and other financial institutions, particularly in the field of marketing and risk management.

A Possible Proof Of The Riemann Hypothesis

description: In this paper, I present my approach to the Riemann Hypothesis, which potentially provides a proof of it.

I start by simplifying the equality Eta(s)=0 (which is implied by the nullness of the continued Zeta(s)) by expressing |Eta(s)|^2=0 as Re(Eta(s))^2 + Im(Eta(s))^2 = 0, expressed with cosine and sine functions, then I use trigonometric identities to further break down the sum into a sum of squares purely relying on Re(s) and a double sum relying on both Re(s) and Im(s).

Using the bounded nature of the cosine function, I reformulate the equality as a problem of quadratic equations, to get rid of the dependence on Im(s) as well as the oscillations it induces,

I then consider Re(s) as a map a[n] = Re(s[n]) (n being the number of terms in Zeta(s)), rather than a fixed value (since we deal with infinity),

It has already been proved that for all the nontrivial zeros, their real part is in ]0,1[,

So, I then use integrals and asymptotic analysis to observe three cases of asymptotic behaviours:

when a[n] converges to a real number in ]0,1/2[

when a[n] converges to a real number in ]1/2,1[

when a[n] converges to 1/2 (where we distinguish some more cases)

Then I conclude that the only logically consistent case is when a[n] converges to 1/2.
Anisotropic dynamics in a shaken granular dimer gas experiment

description: The dynamics, velocity fluctuations, and particle-plate interactions for a 2D granular gas of shaken, non-spherical particles are studied experimentally. The experiment consists of a horizontal plate that is vertically oscillated to drive the dynamics of macroscopic dimers, spherical pairs that are loosely connected by a rod that couple the interaction each of the spheres has with the shaking plate. The extended nature of the particles results in more than one energy-momentum transfer between the plate and each dimer per shaking cycle. This complex interaction results in anisotropic behavior for the dimer that is a function of the shaking parameters.

Atmospheric dispersion correction: model requirements and impact on radial velocity measurements

description: Observations with ground-based telescopes are affected by differential atmospheric dispersion when seen at a zenith angle different from zero, a consequence of the wavelength-dependent index of refraction of the atmosphere. One of the pioneering technology in detecting exoplanets is the technique of radial velocity (RV), that can be affected by uncorrected atmospheric dispersion. The current highest precision spectrographs are expected to deliver a precision of 10 cm/s (e.g., ESPRESSO). To minimize the atmospheric dispersion effect, an Atmospheric Dispersion Corrector (ADC) can be employed. ADC designs are based on sky dispersion models that nonetheless give different results; these can reach a few tens of milli-arcseconds (mas) in the sky (a difference up to 40 mas); a value close to the current requirements (20 mas in the case of ESPRESSO). In this paper we describe tests done with ESPRESSO and HARPS to understand the influence of atmospheric dispersion and its correction on RV precision. We also present a comparison of different sky models, using EFOSC2 data (between 600nm and 700nm), that will be used to improve on the design of ADCs.

FUSE and STIS Observations of the Warm-Hot Intergalactic Medium towards PG1259+593

description: We use FUSE and STIS spectra to study intergalactic absorption towards the quasar PG1259+593 (z=0.478). We identify 135 intergalactic absorption lines with equivalent widths >10mA, tracing 78 absorption components in 72 Ly alpha/beta absorption-line systems. We concentrate on the distribution and physical properties of the WHIM as sampled by OVI and intrinsically broad Ly alpha lines. The number of intervening OVI absorbers for equivalent widths W>24 mA is 3-6 over an unobscured redshift path of dz=0.368. This implies a number density of OVI systems, dN/dz, of ~8-16 along this sight line. This range is consistent with estimates from other sight lines, supporting the idea that intervening intergalactic OVI absorbers contain an substantial fraction of the baryonic mass in the low-redshift Universe. We identify a number of broad Ly alpha absorbers with large Doppler parameters (b~40-200 km/s) and low column densities (N(HI)<10^14 cm^-2). For pure thermal broadening, these widths correspond to temperatures of ~1x10^5 to 3x10^6 K. While these broad absorbers could be caused by blends of multiple, unresolved lines, continuum undulations, or by kinematic flows and Hubble broadening, we consider the possibility that some of these features are single-component, thermally broadened Ly alpha lines. These systems could represent WHIM absorbers that are too weak, too metal-poor, and/or too hot to be detected in OVI. If so, their widths and their frequency in the PG1259+593 spectrum imply that these absorbers trace an even larger fraction of the baryons in the low-redshift Universe than the OVI absorbing systems (abridged version).

description: This article examines the relationship between ethnic diversity, redistributive policies and income inequality in the context of Mexican municipalities. Although we primarily focus on income inequality within municipalities, we are also interested in how ethnic diversity and redistribution affect income disparities between municipalities. This study uses multiple data sets to construct original measures of mean household income, income inequality, ethnolinguistic diversity and redistributive policies at the municipality level. Based on these variables, we carry out several econometric analyses accounting for endogeneity and spatial autocorrelation issues. First, while there is a clear negative impact of ethnic diversity on municipal mean income, the relevance of the redistribution channel in the mediation of this relationship seems to be partially relevant among Mexican municipalities. Second, our empirical investigations emphasise that the impact of ethnic diversity on intra-municipal income inequality depends on the extent of redistributive policies. More precisely, we show that ethnic diversity has a negative effect on inequality among municipalities with low levels of redistribution and that this inequality-reducing effect weakens along with increasing levels of redistribution until reaching a turning point. Our findings call for further research about the main channels through which ethnic diversity may affect redistribution and income inequality.
A Future Linear Collider with polarised beams: Searches for New Physics

description: There exists a world--wide consensus for a future $e^+e^-$ Linear Collider in the energy range between $\sqrt{s}=500--1000$ GeV as the next large facility in HEP. The Linear Collider has a large physics potential for the discovery of new physics beyond the Standard Model and for precision studies of the Standard Model itself. It is well suited to complement and extend the physics program of the LHC. The use of polarised beams at a Linear Collider will be one of the powerful tools. In this paper some highlights of searches for physics beyond the Standard Model at a future Linear Collider with polarised $e^-$ and $e^+$ beams are summarised.

description: In Landau gauge QCD the infrared behavior of the propagator of transverse gluons can be analytically determined to be a power law from Dyson-Schwinger equations. This propagator clearly shows positivity violation, indicating the absence of the transverse gluons from the physical spectrum, i.e. gluon confinement. A simple analytic structure for the gluon propagator is proposed capturing all important features. We provide arguments that the Landau gauge quark propagator possesses a singularity on the real timelike axis. For this propagator we find a positive definite Schwinger function.
