description: One of the key features of the CAP 2014 reforms is the requirement for Member States currently distributing direct payments to farmers on the basis of historic support levels to switch an area-based payment scheme. This paper explores effects of this shift for both the farm sector and the wider rural economy in North-East Scotland. Analysis is carried out in two stages: First, the changes in payments for individual farm businesses are estimated based on the integration of several agricultural datasets. Second, the wider economy impacts are estimated using an agriculture-focussed static regional CGE model. The farm-level analysis shows that the North-East Scotland region is likely to suffer a significant net payment loss from the change in payment basis; however, there are gainers as well as losers both between and within farm types. The CGE analysis suggests that the wider economic impacts of the change in payments will be limited, in part due to the relatively small size of the sector in the overall economy. Within the agricultural sector itself, real agricultural GDP falls by 0.55%. Small cropping farm households suffer the largest overall income drop (-9.18%), with output from large “other” farm types falling most (-23.59%). Land rents fall across all farm types, and land switches into forestry. In terms of the wider agri-food chain, demand for agricultural intermediate inputs falls by 3% while the impacts on the downstream food sectors are more limited with meat processing predicted to fall most in percentage terms (-1.47%) due to increased raw imports from other regions. The paper concludes by suggesting areas for further research.

description: The possibility of nonlinear pulses generation in Yttrium Iron Garnet thin films for arbitrary direction between waveguide and applied static in-plane magnetic field is considered. Up to now only the cases of in-plane magnetic fields either perpendicular or parallel to waveguide direction have been studied both experimentally and theoretically. In the present paper it is shown that also for other angles (besides 0 or 90 degrees) between a waveguide and static in-plane magnetic field the stable bright or dark (depending on magnitude of magnetic field) solitons could be created.

description: Crop insurance markets are exposed to unpredictable weather conditions. Yield risks are systemic in nature, and public intervention is often a necessity for the functioning private crop insurance markets. Climate change is expected to increase catastrophic weather events and yield volatility. This paper addresses the question how government actions related to extreme weather events affect the demand and farmers willingness to pay for crop insurance products. The analysis is based on farmers’ stated preferences with split data approach. Our results reveal that farmers’ willingness to pay for crop insurance was different when government disaster relief was possible compared to the situation where disaster relief was not possible. Results show that possibility for disaster relief payments in catastrophic event will lead to extensive misuse of taxpayers’ money if crop insurance premiums are subsidized simultaneously.

description: We explore the physics of a new neutral gauge boson, ($Z^\prime$), coupling to only third-generation particles with a mass near the electroweak gauge boson mass poles. A $Z^\prime$ boson produced by top quarks and decaying to tau leptons is considered. With a simple search strategy inspired by existing analyses of the standard model gauge boson production in association with top quarks, we show that the Large Hadron Collider has good exclusionary power over the model parameter space of the $Z^\prime$ boson even at the advent of the high-luminosity era. It is shown that the $t\bar{t}Z^\prime$ process allows one to place limits on right-handed top couplings with a $Z^\prime$ boson that preferentially couples to third generation fermions, which are at present very weakly constrained.

description: This paper examines the impacts of non-farm work and land tenancy arrangements on the intensity of investment in soil-improving measures and farm productivity. A multivariate tobit model that accounts for potential endogeneity between the intensity of investment and the non-farm work and tenancy arrangement variables is estimated for 341 rural households in Punjab province of Pakistan. Instrumental variable approach is also used to analyze the impact of tenancy arrangement and non-farm work on farm productivity. The empirical results show that participation in non-farm work and tenure security tend to increase the intensity of investment in long-term soil-improving measures, but decrease chemical fertilizer use intensity. We also find that increases in non-farm work and tenure security exert significant and positive effects on agricultural productivity. Investment in soil conservation measures is also found to significantly increase agricultural productivity.

description: The effect of magnetron power on the room temperature 1.54 $μ$m infra-red photoluminescence intensity of erbium doped AlN films grown by r. f. magnetron sputtering, has been studied. The AlN:Er thin films were deposited on (001) Silicon substrates. The study presents relative photoluminescence intensities of nanocrystallized samples prepared with identical sputtering parameters for two erbium doping levels (0.5 and 1.5 atomic %). The structural evolution of the crystallites as a function of the power is followed by transmission electron microscopy. Copyright line will be provided by the publisher 1 Introduction For some time now, rare-earth (RE)-doped semiconductors represent significant potential applications in the field of opto-electronic technology. Part of this technological interest relies on the shielded 4f levels of the RE ions as they give rise to sharp and strong luminescence peaks [1-5]. Among the RE elements, Er is preferred to its counterparts since the Er ions can produce both visible light at 558 nm (green, one of the primary colours) and IR light at 1.54 $μ$m whose spectrum region coincides with the main low-loss region in the absorption spectrum of silica-based optical fibres, combining so potential applications towards photonic devices and towards optical communication devices operating in the infrared domain. These interesting emissions can however only be exploited when placed into host matrixes. On one side, the shielding of the intra 4f levels prevents the shifting of the RE 3+ energy levels and ensures the frequency emission stability. Moreover the intra 4f transitions are parity forbidden for the isolated ions. Matrixes can render the Er 3+ ions optically active, via a relaxation of selection rules due to crystal field effects. As silicon based materials were tested in the 1960s to the 90s with no clear industrial success it was found that the

description: This paper analyses an incentive payment-based approach to improving food safety in the supply chain. It develops a principal-agent model of the food supply chain in which the principal offers heterogeneous agents a payment to implement costly additional practices to improve food safety. It is shown that the presence or absence of the moral hazard problem affects the balance of benefits and costs from broadening the scope of the system from just lower cost larger agents to include higher cost smaller agents, thereby affecting the optimal design of the system. In particular, broadening the scope of the system to include smaller agents by increasing the size of the incentive payment can ameliorate the moral hazard problem among larger agents to the extent that this more costly approach is socially optimal.

description: This paper aims to make an evaluation of CAP contribution to landscape management in Bulgarian economy of rural areas. To sum up, landscape is a non-commodity output produced as direct or indirect outcome of the activities operating in a particular area and it is valued by society for its functions (use and non use values, ecological, recreational, cultural etc). Due to this complex nature, it produces second-order effects that are captured by the stakeholders in rural areas (farmers or others), and that generate potential markets for new activities. Therefore, through the generation of these effects, landscape contributes to boosting the economy of rural areas and is an important driver for the whole regional economy.....Cilj ovoga rada je ocjena doprinosa Zajedničke poljoprivredne politike u odnosu na upravljanje krajobrazom u bugarskoj ekonomiji u ruralnim područjima. Ukratko, krajobraz je nematerijalni proizvod nastao kao direktni ili indirektni rezultat aktivnosti koje se provode na određenom području, a društvo ga vrednuje na temelju njegovih funkcija (uporabnih i neuporabnih, ekoloških, rekreacijskih, kulturnih itd.). Zbog svoje kompleksnosti stvara efekte drugog reda, koje koriste pripadnici interesnih skupina u ruralnim područjima (poljoprivrednici i ostali), ali i potencijalno tržište za nove aktivnosti. Stoga nastankom ovih efekata, krajobraz doprinosi rastu ekonomije ruralnih područja i predstavlja značajan pokretač ukupne regionalne ekonomije.

description: This paper attempts to (1) shed some light on the EC- US controversy concerning the effect of the EC oilseeds market regime on EC imports of US soybean products, essentially soy meal, and (2) provide information on another EC- US controversy: Does corn-gluten feed behave as a substitute for (EC view) or a complement to (US view) feed grains, and do EC corn-gluten feed imports displace EC grain production or not? By using a constrained vectorial autoregressive model of Rotterdam prices for soy meal, sunflower meal, rape meal, corn-gluten feed and cassava, we show that (1) the decrease in EC imports of US soymeal are mot mainly caused by the EC milling subsidies, and (2) corngluten feed is both a substitute for soymeal due to its protein content and a substitute for cassava (and grains) due to its energy content: US and EC views are only partial views.

description: We present an analysis of the gas dynamics of star-forming galaxies at z~1.5 using data from the KMOS Galaxy Evolution Survey (KGES). We quantify the morphology of the galaxies using $HST$ CANDELS imaging parametrically and non-parametrically. We combine the H$α$ dynamics from KMOS with the high-resolution imaging to derive the relation between stellar mass (M$_{*}$) and stellar specific angular momentum (j$_{*}$). We show that high-redshift star-forming galaxies at z~1.5 follow a power-law trend in specific stellar angular momentum with stellar mass similar to that of local late-type galaxies of the form j$_*$$\propto$M$_*^{0.53 \pm 0.10}$. The highest specific angular momentum galaxies are mostly disc-like, although generally, both peculiar morphologies and disc-like systems are found across the sequence of specific angular momentum at a fixed stellar mass. We explore the scatter within the j$_{*}$-M$_{*}$ plane and its correlation with both the integrated dynamical properties of a galaxy (e.g. velocity dispersion, Toomre Q$_{\rm g}$, H$α$ star formation rate surface density $Σ_{\rm SFR}$) and its parameterised rest-frame UV/optical morphology (e.g. Sérsic index, bulge to total ratio, Clumpiness, Asymmetry and Concentration). We establish that the position in the j$_{*}$-M$_{*}$ plane is strongly correlated with the star-formation surface density and the Clumpiness of the stellar light distribution. Galaxies with peculiar rest-frame UV/optical morphologies have comparable specific angular momentum to disc-dominated galaxies of the same stellar mass, but are clumpier and have higher star-formation rate surface densities. We propose that the peculiar morphologies in high--redshift systems are driven by higher star formation rate surface densities and higher gas fractions leading to a more clumpy inter-stellar medium.

description: Tobacco production has a long tradition in R. Macedonia. It is an industrial crop with over 70% share in the total industrial crops area, and an average share of some 30%, in total agricultural export. As a labor intensive crop, it provides employment for the rural population and presents a social buffer for the economy and the current high unemployment rate in the country. The aggressive policies against smoking propose reduction of tobacco production, thus solution for its replacement ought to be considered for the tobacco producers in the country. The aim of this research is to investigate the competitiveness of the tobacco sector in the country based on the Porter Diamond competitiveness approach, complemented with the Ballasa index of comparative advantage. Based on the prevailing positive aspects in the competitiveness model, and the high values of the index ranging from seven to over nine for the period 2005-2010; much higher compared to selected countries in the region (Greece, Bulgaria, Turkey), our findings confirm that the country has favorable conditions and competitive advantage for producing tobacco.....Proizvodnja duhana ima dugu tradiciju u Republici Makedoniji. To je industrijska biljka s preko 70% udjela na ukupnom broju površina pod industrijskim i s prosječnim udjelom od oko 30% u ukupnom izvozu poljoprivrednih proizvoda. Kao zahtjevna biljka, osigurava posao ruralnoj populaciji i daje socijalnu zaštitu ekonomiji i trenutnoj visokoj stopi nezaposlenosti u zemlji. Agresivne kampanje protiv pušenja predlažu smanjenje proizvodnje duhana, stoga bi se trebalo pronaći rješenje čime bi ga proizvođači duhana u zemlji mogli zamijeniti. Cilj ovoga istraživanja bilo je istražiti konkurentnost duhanskog sektora u zemlji analizom konkurentnosti pomoću Porter Diamondovog modela, nadopunjenog Ballasa indeksom komparativnih prednosti. Na temelju prevladavajućih pozitivnih aspekata u modelu konkuretnosti visoke vrijednosti indeksa su u rasponu od sedam do preko devet za razdoblje od 2005.-2010.; puno više, ako se usporedi s nekim zemljana u regiji (Grčka, Bugarska, Turska). Naši rezultati potvrđuju da zemlja ima povoljne uvjete i kompetitivne prednosti za proizvodnju duhana.

description: In this work we present the ultra-relativistic $\mathcal{N}$-extended AdS Chern-Simons supergravity theories in three spacetime dimensions invariant under $\mathcal{N}$-extended AdS Carroll superalgebras. We first consider the $(2,0)$ and $(1,1)$ cases; subsequently, we generalize our analysis to $\mathcal{N}=(\mathcal{N},0)$, with $\mathcal{N}$ even, and to $\mathcal{N}=(p,q)$, with $p,q>0$. The $\mathcal{N}$-extended AdS Carroll superalgebras are obtained through the Carrollian (i.e., ultra-relativistic) contraction applied to an $so(2)$ extension of $\mathfrak{osp}(2|2)\otimes \mathfrak{sp}(2)$, to $\mathfrak{osp}(2|1)\otimes \mathfrak{osp}(2,1)$, to an $\mathfrak{so}(\mathcal{N})$ extension of $\mathfrak{osp}(2|\mathcal{N})\otimes \mathfrak{sp}(2)$, and to the direct sum of an $\mathfrak{so}(p) \oplus \mathfrak{so}(q)$ algebra and $\mathfrak{osp}(2|p)\otimes \mathfrak{osp}(2,q)$, respectively. We also analyze the flat limit ($\ell \rightarrow \infty$, being $\ell$ the length parameter) of the aforementioned $\mathcal{N}$-extended Chern-Simons AdS Carroll supergravities, in which we recover the ultra-relativistic $\mathcal{N}$-extended (flat) Chern-Simons supergravity theories invariant under $\mathcal{N}$-extended super-Carroll algebras. The flat limit is applied at the level of the superalgebras, Chern-Simons actions, supersymmetry transformation laws, and field equations.

description: Piezoelectric and ferroelectric ceramics with a high Curie temperature (Tc) have attracted a growing attention owning to their applications under severe environments. In this work, phase structure, dielectric, ferroelectric and piezoelectric properties of (0.975-x)BiScO3-xPbTiO3-0.025Pb(Cd1/3Nb2/3)O3 ceramics (x = 0.58-0.64) were studied. A composition-induced structural transformation occurs from rhombohedral phase to tetragonal phase through an intermediate monoclinic phase with the increasing PT concentration. The relationship between structure and electrical properties of the system were discussed. The BS-xPT-PCN system near the morphotropic phase boundary (x = 0.62) exhibits excellent piezoelectric and ferroelectric performances with d33 = 508 pC/N, kp = 56%, and Pr = 40 uC/cm2. The high-temperature piezoelectricity of the sample with MPB (x = 0.62) was characterized by an in situ XRD. The excellent thermal stability of the crystal structure and the piezoelectric property indicate that the BS-xPT-PCN system is a promising candidate for high temperature piezoelectric applications.

description: Optical spectroscopy of 93 galaxies, 60 projected in the direction of Abell 1367, 21 onto the Coma cluster and 12 on Virgo, is reported. The targets were selected either because they were detected in previous Hα, UV or r' surveys. The present observations bring to 100% the redshift completeness of Hαselected galaxies in the Coma region and to 75% in Abell 1367. All observed galaxies except one show Hαemission and belong to the clusters. This confirms previous determinations of the Hαluminosity function of the two clusters that were based on the assumption that all Hαdetected galaxies were cluster members. Using the newly obtained data we re-determine the UV luminosity function of Coma and we compute for the first time the UV luminosity function of A1367. Their faint end slopes remain uncertain (-2.00 < α< -1.35) due to insufficient knowledge of the background counts. If 90% of the UV selected galaxies without redshift will be found in the background (as our survey indicates), the slope of UV luminosity function will be α~ -1.35, in agreement with the UV luminosity function of the field (Sullivan et al. 2000) and with the H$α$ luminosity functions of the two clusters (Iglesias-Paramo et al. 2002). We discover a point like Hαsource in the Virgo cluster, associated with the giant galaxy VCC873, possibly an extragalactic HII region similar to the one recently observed in Virgo by Gerhard et al. (2002).

 Distribution
 Previously recorded (see Kott 2002): Western Australia (Barrow I., Rowley Shoals, Dampier Archipelago, Cape Preston, Montebello Is, North West Cape, Learmouth, Shark Bay, Cervantes). New records: Queensland (18.845 ° S, 146.795 ° E, 26 m; 17.655 ° S, 146.225 ° E, 26 m; 17.145 ° S, 146.205 ° E, 36 m).
 Remarks
Although only one to three small specimens were taken at the newly recorded locations, these do establish that the species known formerly only from the northwestern coast of the continent also occurs on the northeastern continental shelf. The species is readily distinguished by its short muscles that do not extend over the lower half of the body, the simple bilabiate anal border with each lip subdivided, the plain-edged oviducal membrane, and projecting distal end of the vas deferens.

description: The Large Binocular Telescope (LBT) Interferometer (LBTI) is a strategic instrument that combines the two 8.4m apertures of the LBT for sensitive, high-angular resolution imaging and interferometric observations at thermal infrared wavelengths. Through its observing modes making use of Adaptive Optics, Fizeau imaging interferometry, and nulling interferometry, the LBTI makes the LBT in many respects the first ELT-like telescope. It thus serves as a pioneer for future ELTs in terms of both science (angular resolution of a 23m telescope at thermal-infrared wavelengths) and instrumentation (large, sensitive mid-infrared instrumentation, adaptive secondary mirrors, co-phasing large apertures). In the northern hemisphere, the LBTI is also the only thermal-infrared interferometer and the only interferometer using 8m-class telescopes and LBT is as of yet the only ELT-like telescope in operation or under construction. The LBTI has successfully completed a large survey for habitable-zone dust around nearby main sequence stars exploiting its superior angular resolution to obtain a 100x better sensitivity than space-based, precision-photometric observations. More recently, we have emphasized Fizeau interferometry and executed our first extragalactic and N-band observations in this mode, together with high-contrast and precision-astrometric observations. We are now pushing a project attempting to image the first rocky planet in the habitable zone around one of the nearest Sun-like stars. In this article, we present an overview of the LBTI\'s design and capabilities, illustrated by recent science highlights, and outline future developments and observing projects.

description: We develop a recently-proposed mapping of the two-dimensional Ising model with random exchange (RBIM), via the transfer matrix, to a network model for a disordered system of non-interacting fermions. The RBIM transforms in this way to a localisation problem belonging to one of a set of non-standard symmetry classes, known as class D; the transition between paramagnet and ferromagnet is equivalent to a delocalisation transition between an insulator and a quantum Hall conductor. We establish the mapping as an exact and efficient tool for numerical analysis: using it, the computational effort required to study a system of width $M$ is proportional to $M^{3}$, and not exponential in $M$ as with conventional algorithms. We show how the approach may be used to calculate for the RBIM: the free energy; typical correlation lengths in quasi-one dimension for both the spin and the disorder operators; even powers of spin-spin correlation functions and their disorder-averages. We examine in detail the square-lattice, nearest-neighbour $\pm J$ RBIM, in which bonds are independently antiferromagnetic with probability $p$, and ferromagnetic with probability $1-p$. Studying temperatures $T\geq 0.4J$, we obtain precise coordinates in the $p-T$ plane for points on the phase boundary between ferromagnet and paramagnet, and for the multicritical (Nishimori) point. We demonstrate scaling flow towards the pure Ising fixed point at small $p$, and determine critical exponents at the multicritical point.

description: Electrons moving in a conductor can transfer momentum to the lattice via collisions with impurities and boundaries, giving rise to a fluctuating mechanical stress tensor. The root-mean-squared momentum transfer per scattering event in a disordered metal (of dimension L greater than the mean free path l and screening length xi) is found to be reduced below the Fermi momentum by a factor of order l/L for shear fluctuations and (xi/L)^2 for pressure fluctuations. The excitation of an elastic bending mode by the shear fluctuations is estimated to fall within current experimental sensitivity for a nanomechanical oscillator.

description: The multiferroic behavior of CoCr$_2$O$_4$ results from the appearance of conical spin-spiral magnetic ordering, which induces electric polarization. The magnetic ground state has a complex size dependent behavior, which collapses when reaching a critical particle size. Here, the magnetic phase stability of CoCr$_2$O$_4$ in the size range of 3.6 - 14.0 nm is presented in detail using the combination of neutron diffraction with XYZ polarization analysis and macroscopic magnetization measurements. We establish critical coherent domain sizes for the formation of the spin spiral and ferrimagnetic structure and reveal the evolution of the incommensurate spin spiral vector with particle size. We further confirm the presence of ferroelectric polarization in the spin spiral phase for nanocrystalline CoCr$_2$O$_4$.

description: We address the long standing problem of the dependence of the electrostatic persistence length $l_e$ of a flexible polyelectrolyte (PE) on the screening length $r_s$ of the solution within the linear Debye-Huckel theory. The standard Odijk, Skolnick and Fixman (OSF) theory suggests $l_e \propto r_s^2$, while some variational theories and computer simulations suggest $l_e \propto r_s$. In this paper, we use Monte-Carlo simulations to study the conformation of a simple polyelectrolyte. Using four times longer PEs than in previous simulations and refined methods for the treatment of the simulation data, we show that the results are consistent with the OSF dependence $l_e \propto r_s^2$. The linear charge density of the PE which enters in the coefficient of this dependence is properly renormalized to take into account local fluctuations.

description: Temeljni cilj rada je istražiti potrošnju domaćih sokova i soka od bazge na domaćem tržištu, te predložiti ispitanicima veću kupnju funkcionalne hrane. Anketom je obuhvaćeno 120 ispitanika, čiji su rezultati obrađeni SPSS programu za obradu podataka. Dobivenim rezultatima je utvrđeno da su najvažnije čimbenici kod kupnje domaćeg soka okus, cijena i kvaliteta. Dokazano je da trećina ispitanika (33,3%) kupuje domaći sok u supermarketima, što upućuje da bismo tamo usmjerimo razvoj prodajnih kanala. Vidljivo je da potrošači, kupci, proizvođači i trgovci domaćih sokova od bazge pokazuju sklonost kupnji domaćih sokova iako još uvijek u relativno malom postotku......The main goal of this paper is to explore the consumption of homemade juices and of the elderberry juice in the home market as well as to encourage participants to increase consumption of functional foods. 120 participants were included in the survey, the results of which were processed by the SPSS program for data processing. The results indicate that the most important factors in buying homemade juice are taste, price and quality. It is proved that one third of consumers (33.3%) buys homemade juice in supermarkets, which indicates that the development of sales chanel should be supermarket-oriented. It is evident that not only consumers and buyers, but also producers and retailers of elderberry homemade juices are inclined to purchase homemade juices, although in a relatively small percentage.

description: We investigate quantum computation with neutral atoms in optical microtraps where the qubit is implemented in the motional states of the atoms, i.e., in the two lowest vibrational states of each trap. The quantum gate operation is performed by adiabatically approaching two traps and allowing tunneling and cold collisions to take place. We demonstrate the capability of this scheme to realize a square-root of swap gate, and address the problem of double occupation and excitation to other unwanted states. We expand the two-particle wavefunction in an orthonormal basis and analyze quantum correlations throughout the whole gate process. Fidelity of the gate operation is evaluated as a function of the degree of adiabaticity in moving the traps. Simulations are based on rubidium atoms in state-of-the-art optical microtraps with quantum gate realizations in the few tens of milliseconds duration range.

description: With only a few exceptions, the numerical simulation of cosmic and laboratory hydromagnetic dynamos has been carried out in the framework of the differential equation method. However, the integral equation method is known to provide robust and accurate tools for the numerical solution of many problems in other fields of physics. The paper is intended to facilitate the use of integral equation solvers in dynamo theory. In concrete, the integral equation method is employed to solve the eigenvalue problem for a hydromagnetic dynamo model with a spherically symmetric, isotropic helical turbulence parameter alpha. Three examples of the function alpha(r) with steady and oscillatory solutions are considered. A convergence rate proportional to the inverse squared of the number of grid points is achieved. Based on this method, a convergence accelerating strategy is developed and the convergence rate is improved remarkably. Typically, quite accurate results can be obtained with a few tens of grid points. In order to demonstrate its suitability for the treatment of dynamos in other than spherical domains, the method is also applied to alpha^2 dynamos in rectangular boxes. The magnetic fields and the electric potentials for the first eigenvalues are visualized.

description: Tunneling is measured via the quantum levels of a metal nanoparticle. We analyze quantitatively the resonance energies, widths, and amplitudes, both in the regime where only one state is accessible for tunneling and in the non-equilibrium regime when additional states are made accessible one-by-one. For tunneling through one state, our results agree with expectations for sequential tunneling, but in the non-equilibrium regime the resonances are broadened and shifted in ways that require taking into account electron interactions and relaxation.

description: In this work we investigate the practicality of stochastic gradient descent and recently introduced variants with variance-reduction techniques in imaging inverse problems. Such algorithms have been shown in the machine learning literature to have optimal complexities in theory, and provide great improvement empirically over the deterministic gradient methods. Surprisingly, in some tasks such as image deblurring, many of such methods fail to converge faster than the accelerated deterministic gradient methods, even in terms of epoch counts. We investigate this phenomenon and propose a theory-inspired mechanism for the practitioners to efficiently characterize whether it is beneficial for an inverse problem to be solved by stochastic optimization techniques or not. Using standard tools in numerical linear algebra, we derive conditions on the spectral structure of the inverse problem for being a suitable application of stochastic gradient methods. Particularly, we show that, for an imaging inverse problem, if and only if its Hessain matrix has a fast-decaying eigenspectrum, then the stochastic gradient methods can be more advantageous than deterministic methods for solving such a problem. Our results also provide guidance on choosing appropriately the partition minibatch schemes, showing that a good minibatch scheme typically has relatively low correlation within each of the minibatches. Finally, we propose an accelerated primal-dual SGD algorithm in order to tackle another key bottleneck of stochastic optimization which is the heavy computation of proximal operators. The proposed method has fast convergence rate in practice, and is able to efficiently handle non-smooth regularization terms which are coupled with linear operators.
