description: Radio-loud quasars (RLQs) are more X-ray luminous than predicted by the X-ray-optical/UV relation (i.e. $L_\mathrm{x}\propto L_\mathrm{uv}^γ$) for radio-quiet quasars (RQQs). The excess X-ray emission depends on the radio-loudness parameter ($R$) and radio spectral slope ($α_\mathrm{r}$). We construct a uniform sample of 729 optically selected RLQs with high fractions of X-ray detections and $α_\mathrm{r}$ measurements.We find that steep-spectrum radio quasars (SSRQs; $α_\mathrm{r}\le-0.5$) follow a quantitatively similar $L_\mathrm{x}\propto L_\mathrm{uv}^γ$ relation as that for RQQs, suggesting a common coronal origin for the X-ray emission of both SSRQs and RQQs. However, the corresponding intercept of SSRQs is larger than that for RQQs and increases with $R$, suggesting a connection between the radio jets and the configuration of the accretion flow. Flat-spectrum radio quasars (FSRQs; $α_\mathrm{r}>-0.5$) are generally more X-ray luminous than SSRQs at given $L_\mathrm{uv}$ and $R$, likely involving more physical processes. The emergent picture is different from that commonly assumed where the excess X-ray emission of RLQs is attributed to the jets. We thus perform model selection to comparecritically these different interpretations, which prefers the coronal scenario with a corona-jet connection. A distinct jet component is likely important for only a small portion of FSRQs.The corona-jet, disk-corona, and disk-jet connections of RLQs are likely driven by independent physical processes. Furthermore, the corona-jet connection implies that small-scale processesin the vicinity of SMBHs, probably associated with the magnetic flux/topology instead of black-hole spin, are controlling the radio-loudness of quasars.

description: Micronutrient malnutrition affects billions of people world-wide, causing serious health problems. Different micronutrient interventions are currently being used, but their overall coverage is relatively limited. Biofortification - that is, breeding staple food crops for higher micronutrient contents - has been proposed as a new agriculture-based approach. Yet, as biofortified crops are still under development, relatively little is known about their economic impacts and wider ramifications. In this article, the main factors that will influence their future success are discussed, and a methodology for economic impact assessment is presented, combining agricultural, nutrition, and health aspects. Ex ante studies from India and other developing countries suggest that biofortified crops can reduce the problem of micronutrient malnutrition in a cost-effective way, when they are targeted to specific situations. Projected social returns on research investments are high and competitive with productivity-enhancing agricultural technologies. These promising results notwithstanding, biofortification should be seen as a complement rather than a substitute for existing micronutrient interventions, since the magnitude and complexity of the problem necessitate a multiplicity of approaches. Further research is needed to corroborate these findings and to address certain issues still unresolved at this stage.

description: We present new contributions to the decay matrix element $Γ_{12}^q$ of the $B_q$-$\bar B_q$ mixing complex, where $q=d$ or $s$. Our new results constitute the order $α_s^2 N_f$ corrections to the penguin contributions to the Wilson coefficients entering $Γ_{12}^q$ with full dependence on the charm quark mass. This is the first step towards the prediction of the CP asymmetry $a_{\rm fs}^q$ quantifying CP violation in mixing at next-to-next-to-leading logarithmic order (NNLO) in quantum chromodynamics (QCD) and further improves the prediction of the width difference $ΔΓ_q$ between the two neutral-meson eigenstates. We find a sizable effect from the non-zero charm mass and our partial NNLO result decreases the NLO penguin corrections to $a_{\rm fs}^q$ by 37\% and those to $ΔΓ_q$ by 16\%. We further update the Standard-Model NLO predictions for $a_{\rm fs}^q$ and the ratio of the width and mass differences of the $B_q$ eigenstates: If we express the results in terms of the pole mass of the bottom quark we find $a_{\rm fs}^s=(2.07 \pm 0.10)\cdot 10^{-5}$, $a_{\rm fs}^d=(-4.71 \pm 0.24)\cdot 10^{-4}$, $ΔΓ_s/Δ{M}_s = (4.33 \pm 1.26)\cdot 10^{-3}$, and $ΔΓ_d/Δ{M}_d = (4.48 \pm 1.19)\cdot 10^{-3}$. In the $\overline{\rm MS}$ scheme these numbers read $a^s_{\rm fs} =(2.04 \pm 0.11)\cdot 10^{-5}$, $a^d_{\rm fs} = (-4.64 \pm 0.25)\cdot 10^{-4}$, $ΔΓ_s/Δ{M}_s = (4.97 \pm 1.02)\cdot 10^{-3}$, and $ΔΓ_d/Δ{M}_d = (5.07 \pm 0.96)\cdot 10^{-3}$.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Using explicit solutions of the QCD transport equations, we construct an effective potential for an anisotropic quark-gluon plasma which under plausible assumptions holds beyond the Hard Loop approximation. The configurations, which are unstable in the linear response approach, are characterized by a negative quadratic term of the effective potential. The signs of higher order terms can be either negative or positive, depending on the parton momentum distribution. In the case of a Gaussian momentum distribution, the potential is negative and unbound from below. Therefore, the modes, which are unstable for gauge fields of small amplitude, remain unstable for arbitrary large amplitudes. We also present an example of a momentum distribution which gives a negative quadratic term of the effective potential but the whole potential has a minimum and it grows for sufficiently large gauge fields. Then, the system is weakly unstable. The character of the instability is important for the dynamical evolution of the plasma system.

description: Rapid economic growth in China has resulted in substantially improved household incomes. Diets have also changed, with a movement away from traditional foods and towards animal products and processed foods. Yet micronutrient deficiencies, particularly for calcium and vitamin A, are still widespread in China. In this research we model the determinants of the intakes of these two micronutrients using household panel data, asking particularly whether continuing income increases are likely to cause the deficiencies to be overcome. Nonparametric kernel regressions and random effects panel regression models are employed. The results show a statistically significant but relatively small positive income effect on both nutrient intakes. The local availability of milk is seen to have a strong positive effect on intakes of both micronutrients. Thus, rather than relying on increasing incomes to overcome deficiencies, supplementary government policies, such as school milk programmes, may be warranted.

description: We calculate the B -> D and B -> D* form factors at zero recoil in Staggered Chiral Perturbation Theory. We consider heavy-light mesons in which only the light (u, d, or s) quark is staggered; current lattice simulations generally use a highly improved action such as the Fermilab or NRQCD action for the heavy (b or c) quark. We work to lowest nontrivial order in the heavy quark expansion and to one-loop in the chiral expansion. We present results for a partially quenched theory with three sea quarks in which there are no mass degeneracies (the "1+1+1" theory) and for a partially quenched theory in which the u and d sea quark masses are equal (the "2+1" theory). We also present results for full (2+1) QCD, along with a numerical estimate of the size of staggered discretization errors. Finally, we calculate the finite volume corrections to the form factors and estimate their numerical size in current lattice simulations.

description: Although health is an important factor in economic development, millions of China's rural residents have no medical coverage. Nearly 10 percent of those that were sick in rural China consciously did not seek medical care, mostly because of financial constraints. More than 25% of rural residents are dissatisfied with their village's health system. In response to this deteriorating situation, a new cooperative medical system (NCMS) was initialized in rural China in 2003 by the government. However, after two years of trials, there has been no household-based, economic analysis of the program. This paper provides one of the first. Although where introduced, most rural residents voluntarily participate, there are many problems with the program. First, at least in its initial years, targeting has been poor; the program has been adopted in richer villages, even though there is a case that there are higher medical needs in poorer villages. Also, while the government subsidy pays part of the premium, more than 40% criticize the design of the program, including complaints about coverage, reimbursement rates and procedures. Based on our survey, the major concern is the extremely low reimbursement rates. Instead of up to 30% as promised, only 3% of total medical expenses of program participants were paid (6% for inpatient expenses). The expected payout of a participating farmer is actually negative; the farmer receives back less than what he/she puts in. There also is a gap in understanding of farmers and clinicians between the actual implementation of reimbursements and policy.

description: M dwarf stars are high-priority targets for searches for Earth-size and potentially Earth-like planets, but their planetary systems may form and evolve in very different circumstellar environments than those of solar-type stars. To explore the evolution of these systems, we obtained transit spectroscopy and photometry of the Neptune-size planet orbiting the ~650 Myr-old Hyades M dwarf K2-25. An analysis of the variation in spectral line shape induced by the Doppler "shadow" of the planet indicate that the planet's orbit is closely aligned with the stellar equator (lambda = -1.7+5.8/-3.7 deg), and that an eccentric orbit found by previous work could arise from perturbations by another planet on a co-planar orbit. We detect no significant variation in the depth of the He I line at 1083 nm during transit. A model of atmospheric escape as a isothermal Parker wind with a solar composition show that this non-detection is not constraining compared to escape rate predictions of ~0.1 Mearth/Gyr; at such rates, at least several Gyr are required for a Neptune-like planet to evolve into a rocky super-Earth.

description: The energy spectrum of the $^{12}C$ nucleus with $(J^π, T)=(0^+,0)$ and $(2^+,0)$ is investigated in the framework of the multicluster dynamical model by using a deep $αα$-potential with forbidden states in the S and D waves. A very high sensitivity of the compact ground and first excited $2^+_1$ states energy levels to the description of the two-body forbidden states wave functions has been estabilished. It is shown also that the chosen method of orthogonalizing pseudopotentials yields convergent results for the energies of the excited $(0^+_2,0)$ and $(0^+_3,0)$ states of the $^{12}C$ nucleus with a well developed cluster like structure.

description: Although livestock forms a very important component of the livelihoods of rural populations of developing countries, productivity remains very low. Livestock keepers are beset by various constraints. In sub-Saharan Africa, cattle are exposed to a number of tropical diseases and other environmental stresses. Breed improvement programs provides key entry points for increasing productivity in cattle populations, especially those plagued by animal diseases. However, breed improvement programs have tended to focus on single, market-driven production traits in isolation of broader livestock system functions. This potentially leads to genotypes that are not well adapted to the environment and not suitable for performing the multiple roles of cattle in developing countries. In order to design a sustainable breed improvement program, farmer preferences for cattle traits need to be integrated into the breeding objective. To explore preferences for cattle traits by cattle keepers, data are used from a choice experiment household survey from a sample of 507 cattle keeping households in trypanosomosis challenge areas in Kenya and Ethiopia. A multinomial logit and mixed logit models are applied to estimate the economic values of preferred cattle traits. The results show existence of preference heterogeneity for cattle traits based on cattle production systems. Further, the results suggest that important traits in developing breed improvement programs should include trypanotolerance, fitness to traction, drought tolerance and fecundity, drawing implications on conservation of breeds which possess these traits.

description: The evolution of the full repertoire of proteins encoded in a given genome is mostly driven by gene duplications, deletions, and sequence modifications of existing proteins. Indirect information about relative rates and other intrinsic parameters of these three basic processes is contained in the proteome-wide distribution of sequence identities of pairs of paralogous proteins. We introduce a simple mathematical framework based on a stochastic birth-and-death model that allows one to extract some of this information and apply it to the set of all pairs of paralogous proteins in seven model organisms. It was found that the histogram of sequence identities p generated by an all-to-all alignment of all protein sequences encoded in a genome is well fitted with a power-law form ~p^(-gamma) with the value of the exponent gamma around 4 for the majority of organisms used in this study. This implies that the intra-protein variability of substitution rates is best described by the Gamma-distribution with the exponent alpha ~ 0.33. We separately measure the short-term (``raw'') duplication and deletion rates r*_dup, r*_del which include gene copies that will be removed soon after the duplication event and their dramatically reduced long-term counterparts r_dup, r_del. Systematic trends of each of the four duplication/deletion rates with the total number of genes in the genome were analyzed. All but the deletion rate of recent duplicates r*_del were shown to systematically increase with N_genes. Abnormally flat shapes of sequence identity histograms observed for yeast and human are consistent with lineages leading to these organisms undergoing one or more whole-genome duplications.

description: The rapidly growing beef cattle herd of the Peoples Republic of China is largely carried as small numbers of animals on smallholder farms. These enterprises have traditionally focussed on cereal and vegetable crops. Limited plantings of specialised forages combined with a poor knowledge of ruminant nutrition by sm allholder farmers represent a serious challenge to establishing genuinely sustainable beef enterprises for this sector. Government policy to promote beef cattle production on smallholder farms is now focussing on the use of new forages and improved feeding practices. The paper draws on some economic insights from an Australian Centre for International Agricultural Research (ACIAR) project that is exploring options for integrating the planting and feeding of improved forages within existing smallholder farming systems in the Red Soils Region of south-central China. An economic model and a synthetic case example of a smallholder farm enterprise are used to briefly explore the economic potential of such options. The impact of changing values for two critical profit drivers (selling price and liveweight gain) are considered along with some implications for cattle feeding systems on smallholder farms in the Red Soils Region.

description: About 20% of all B-type stars are classical Be stars. The Be phenomenon is strongly correlated with rapid rotation, the origin of which remains unclear. It may be rooted in single- or binary-star evolution. In the framework of the binary channel, the initially more massive star transfers mass and angular momentum to the original secondary, which becomes a Be star. The system then evolves into a Be binary with a post-main-sequence companion, which may later be disrupted in a supernova event. Hence, if the binary channel dominates the formation of Be stars, one may expect a strong lack of close Be binaries with main sequence (MS) companions. Through an extensive, star-by-star review of the literature of a magnitude-limited sample of Galactic early-type Be stars, we investigate whether Be binaries with MS companions are known to exist. Our sample is constructed from the BeSS database and cross-matched with all available literature on the individual stars. Out of an initial list of 505 Be stars, we compile a final sample of 287 Galactic Be stars earlier than B1.5 with V<=12 mag. Out of those, 13 objects were reported as Be binaries with known post-MS companions and 11 as binaries with unknown, uncertain or debated companions. We find no confirmed reports of Be binaries with MS companions. For the remaining 263 targets, no significant reports of multiplicity exist in the literature, implying that they are either Be binaries with faint companions, or truly single. The clear lack of reported MS companions to Be stars, which stands in contrast to the high number of detected B+B MS binaries, strongly supports the hypothesis that early-type Be stars are binary interaction products that spun up after mass and angular momentum transfer from a companion star. Taken at face value, our results may suggest that a large majority of the early-type Be stars have formed through binary mass-transfer.

description: As it has already done for Earth, the sun, and the stars, seismology has the potential to radically change the way the interiors of giant planets are studied. In a sequence of events foreseen by only a few, observations of Saturn's rings by the Cassini spacecraft have rapidly broken ground on giant planet seismology. Gravity directly couples the planet's normal mode oscillations to the orbits of ring particles, generating spiral waves whose frequencies encode Saturn's internal structure and rotation. These modes have revealed a stably stratified region near Saturn's center, and provided a new constraint on Saturn's rotation.

description: The measurement of total factor productivity in agriculture has been recently extended in order to include some 'bad' outputs that are jointly produced along with agricultural goods. In this paper, total factor productivity is decomposed into its determining factors and nitrate pollution is treated as an environmentally detrimental input. A restricted variable cost function is specified for Greek agriculture for the period 1969-1996. A constraint is assumed on nitrate pollution and the TFP estimates, which are obtained, are then decomposed into the rate of technical change effect, the scale effect and the market disequilibrium effect.

Assuming spherical geometry, the radius of the seed-photons emitting region is ~17 km. The source shows no hard X-ray emission; it was detected only at a 3 sigma level above 40 keV. We also analyzed public ISGRI data of Cyg X--2 to investigate the presence of a hard X-ray component. We report the possible presence of hard X-ray emission in one data set.

description: The World Wide Web is still a new technology. In higher internationalization sectors, firms are not only expected to adopt new technologies quickly, but also do so in a simultaneous manner across countries. Nonetheless, the food industry is a lower internationalization sector, meaning that adoption of new technologies (such as the web) may be taking place at a slower pace. We check the overall hypothesis that the Greek food firms are lagging behind their counterparts in other Western countries with respect to their web presence. We investigate this hypothesis by comparing and contrasting the functionality, usability, efficiency and reliability of the web sites of 119 food and 56 beverage Greek and 98 overseas food companies. Our hypothesis is confirmed.

description: The formation of circumstellar disks is investigated using three-dimensional resistive magnetohydrodynamic simulations, in which the initial prestellar cloud has a misaligned rotation axis with respect to the magnetic field. We examine the effects of (i) the initial angle difference between the global magnetic field and the cloud rotation axis ($θ_0$) and (ii) the ratio of the thermal to gravitational energy ($α_0$). We study $16$ models in total and calculate the cloud evolution until $\sim \! 5000$ yr after protostar formation. Our simulation results indicate that an initial non-zero $θ_0$ ($> 0$) promotes the disk formation but tends to suppress the outflow driving, for models that are moderately gravitationally unstable, $α_0 \lesssim 1$. In these models, a large-sized rotationally-supported disk forms and a weak outflow appears, in contrast to a smaller disk and strong outflow in the aligned case ($θ_0 = 0$). Furthermore, we find that when the initial cloud is highly unstable with small $α_0$, the initial angle difference $θ_0$ does not significantly affect the disk formation and outflow driving.

description: We obtain a first order post-Minkowskian two-body effective potential whose post-Newtonian expansion directly reproduces the Einstein-Infeld-Hoffmann potential. Post-Minkowskian potentials can be extracted from on-shell scattering amplitudes in a quantum field theory of scalar matter coupled to gravity. Previously, such potentials did not reproduce the Einstein-Infeld-Hoffmann potential without employing a suitable canonical transformation. In this work, we resolve this issue by obtaining a new expression for the first-order post-Minkowskian potential. This is accomplished by exploiting the reference frame dependence that arises in the scattering amplitude computation. Finally, as a check on our result, we demonstrate that our new potential gives the correct scattering angle.

description: Non-local boxes are hypothetical ``machines'' that give rise to superstrong non-local correlations, leading to a stronger violation of Bell/CHSH inequalities than is possible within the framework of quantum mechanics. We show how non-local boxes can be used to perform any two-party secure computation. We first construct a protocol for bit commitment and then show how to achieve oblivious transfer using non-local boxes. Both have been shown to be impossible using quantum mechanics alone.

description: The radioactive decay of aluminum-26 ($^{26}$Al) is an important heating source in early planet formation. Since its discovery, there have been several mechanisms proposed to introduce $^{26}$Al into protoplanetary disks, primarily through contamination by external sources. We propose a local mechanism to enrich protostellar disks with $^{26}$Al through irradiation of the protostellar disk surface by cosmic rays accelerated in the protostellar accretion shock. We calculate the $^{26}$Al enrichment, [$^{26}$Al/$^{27}$Al], at the surface of the protostellar disk in the inner AU throughout the evolution of low-mass stars, from M-dwarfs to proto-Suns. Assuming constant mass accretion rates, $\dot{m}$, we find that irradiation by MeV cosmic rays can provide significant enrichment on the disk surface if the cosmic rays are not completely coupled to the gas in the accretion flow. Importantly, we find that low accretion rates, $\dot{m} < 10^{-7}$ M$_{\odot}$ yr$^{-1}$, are able to produce canonical amounts of $^{26}$Al, $[^{26}{\rm Al}/^{27}{\rm Al}] \approx 5\times10^{-5}$. These accretion rates are experienced at the transition from Class I- to Class II-type protostars, when it is assumed that calcium-aluminum-rich inclusions condense in the inner disk. We conclude that irradiation of the inner disk surface by cosmic ray protons accelerated in accretion shocks at the protostellar surface may be an important mechanism to produce $^{26}$Al. Our models show protostellar cosmic rays may be a viable model to explain the enrichment of $^{26}$Al found in the Solar System.

description: Relic galaxies are thought to be the progenitors of high-redshift red nuggets that for some reason missed the channels of size growth and evolved passively and undisturbed since the first star formation burst (at $z>2$). These local ultracompact old galaxies are unique laboratories for studying the star formation processes at high redshift and thus the early stage of galaxy formation scenarios. Counterintuitively, theoretical and observational studies indicate that relics are more common in denser environments, where merging events predominate. To verify this scenario, we compared the number counts of a sample of ultracompact massive galaxies (UCMGs) selected within the third data release of the Kilo Degree Survey, that is, systems with sizes $R_{\rm e} < 1.5 \, \rm kpc$ and stellar masses $M_{\rm \star} > 8 \times 10^{10}\, \rm M_{\odot}$, with the number counts of galaxies with the same masses but normal sizes in field and cluster environments. Based on their optical and near-infrared colors, these UCMGs are likely to be mainly old, and hence representative of the relic population. We find that both UCMGs and normal-size galaxies are more abundant in clusters and their relative fraction depends only mildly on the global environment, with denser environments penalizing the survival of relics. Hence, UCMGs (and likely relics overall) are not special because of the environment effect on their nurture, but rather they are just a product of the stochasticity of the merging processes regardless of the global environment in which they live.

description: This paper investigates the relationship between the consumption of selected food nutrients and various socioeconomic factors in Greece. Linear multiple regression analysis was used to estimate the relationship between the consumption of each nutrient and the socioeconomic factors hypothesized to influence it. Data from the 1993/94 family budget survey were used in the analysis. Results show that nutrient consumption increases when moving to higher income levels, with a decreasing rate. Most socioeconomic factors other than income, also influence nutrient consumption significantly.

description: It is not well understood whether the growth of early-type cluster galaxies proceeds inside-out, outside-in, or at the same pace at all radii. In this work we measured the galaxy size, defined by the radius including 80\% of the galaxy light, non-parametrically. We also determined a non-parametric estimate of galaxy light concentration, which measures the curvature of the surface brightness profile in the galaxy outskirts. We used an almost random sampling of a mass-limited sample formed by 128 morphologically early-type galaxies in clusters with $\log M/M_{\odot} \ga 10.7$ spanning the wide range $0.17

A Chandra X-ray survey of nearby dwarf starburst galaxies: I. Data reduction and results

description: (abridged) We present an analysis of Chandra X-ray observations of a sample of eight dwarf starburst galaxies (I Zw 18, VII Zw 403, NGC 1569, NGC 3077, NGC 4214, NGC 4449, NGC 5253, and He 2-10). Extended, diffuse X-ray emission is detected in all but two of the objects. Unresolved sources were found within all dwarf galaxies (total: 55 sources). These point sources are well fit by power law, thermal plasma, or black body models. Ten of the point sources exceed an X-ray luminosity of 10^39 erg s^-1 (ultraluminous X-ray sources). In those galaxies where diffuse X-ray emission is detected, this emission (with X-ray luminosities ranging from 4x10^38 erg s^-1 to 2x10^40 erg s^-1) contains most (60-80 per cent) of the X-ray photons. This diffuse emission can be well fit by MeKaL one-temperature thermal plasma models once the contribution from the unresolved point sources is subtracted properly. The diffuse X-ray component is significantly extended, reaching as far as 0.5-5 kpc into the outskirts of their hosts. Temperatures of various regions within the galaxies range from 1.6-7.6x10^6 K. With few exceptions, temperatures of the hot gas are remarkably uniform, hovering around 2-3x10^6 K. Temperatures of the coronal gas in the outer regions are in general ~2-3 times lower than those found in the central regions. Fits to the diffuse emission do not allow strong constraints to be put on the metallicities of the emitting plasmas. However, the derived metallicities are compatible with those determined from their HII regions. An alpha/Fe ratio of ~2 is indicated for the hot gas within at least three objects (NGC 1569, NGC 4449, and He 2-10).

description: The standard model Higgs quartic coupling vanishes at $(10^{9}-10^{13})$ GeV. We study $SU(2)_L \times SU(2)_R \times U(1)_{B-L}$ theories that incorporate the Higgs Parity mechanism, where this becomes the scale of Left-Right symmetry breaking, $v_R$. Furthermore, these theories solve the strong CP problem and predict three right-handed neutrinos. We introduce cosmologies where $SU(2)_R \times U(1)_{B-L}$ gauge interactions produce right-handed neutrinos via the freeze-out or freeze-in mechanisms. In both cases, we find the parameter space where the lightest right-handed neutrino is dark matter and the decay of a heavier one creates the baryon asymmetry of the universe via leptogenesis. A theory of flavor is constructed that naturally accounts for the lightness and stability of the right-handed neutrino dark matter, while maintaining sufficient baryon asymmetry. The dark matter abundance and successful natural leptogenesis require $v_R$ to be in the range $(10^{10}-10^{13})$ GeV for freeze-out, in remarkable agreement with the scale where the Higgs quartic coupling vanishes, whereas freeze-in requires $v_R \gtrsim 10^9$ GeV. The allowed parameter space can be probed by the warmness of dark matter, precise determinations of the top quark mass and QCD coupling by future colliders and lattice computations, and measurement of the neutrino mass hierarchy.

description: This paper investigates the relationship between cigarette consumption per capita net disposable income, cigarette price index, and per capita expenditure for education. In this empirical analysis the Johansen cointegration test is applied in conjunction with the vector error correction model. Finally, the forecasting technique of cigarettes consumption in Greece using cointegration models is presented as well. This technique presupposes the formation of a structural equations system, which includes the short-run and the long-run relationships of the model variables.

description: We recently argued that a self-propelled particle is formally equivalent to a system consisting of two subsystems coupled by a non-reciprocal interaction [Phys. Rev. E 100, 050603(R) (2019)]. Here we show that this non-reciprocal coupling allows to extract useful work from a single self-propelled particle maintained at constant temperature, by using an aligning interaction to influence correlations between the particle's position and self-propulsion.
