description: Incompatible, i.e. non-jointly measurable quantum measurements are a necessary resource for many information processing tasks. It is known that increasing the number of distinct measurements usually enhances the incompatibility of a measurement scheme. However, it is generally unclear how large this enhancement is and on what it depends. Here, we show that the incompatibility which is gained via additional measurements is upper and lower bounded by certain functions of the incompatibility of subsets of the available measurements. We prove the tightness of some of our bounds by providing explicit examples based on mutually unbiased bases. Finally, we discuss the consequences of our results for the nonlocality that can be gained by enlarging the number of measurements in a Bell experiment.

Grid and Energy System Integration

description: 32nd European Photovoltaic Solar Energy Conference and Exhibition; 2721-2725
description: In this work are reported the analysis as obtained from an advanced simulator implemented to model
the dynamic behavior of grid connected systems composed of photovoltaic plant, electric storage systems of different
technologies and electric loads. By means of a specially developed modeling, the behavior of the systems from the
electric and energy point of view has been analyzed in detail. The simulator allows the calculation for the entire
system life time and for fixed size of photovoltaic generator and storage system capacity, the energy flows among the
individual systems and all electrical quantities of interest sampling at one second.
The behavior of the energy management system (EMS) has been also modeled. Optimized management logic have
been developed in the simulator and then uploaded in the controller of the demonstration plant that has been installed
close to ENEA Centre at Lampedusa island.
The economic benefits introduced by electric storage systems in grid-connected photovoltaic plants has been
evaluated with the aid of the simulator for different types of users.

description: We study kaon-nucleon systems in the Skyrme model in a method based on the bound state approach of Callan-Klebanov but with the kaon around the physical nucleon of the rotating hedgehog. This corresponds to the variation after projection, reversing the order of semiclassical quantization of $1/N_c$ expansion. The method, however, is considered to be suited to the study of weakly interacting kaon-nucleon systems including loosely $\bar{K}N$ bound states such as $Λ(1405)$. We have found a bound state with binding energy of order ten MeV, consistent with the observed state. We also discuss the $\bar{K}N$ interaction and find that it consists of an attraction in the middle range and a repulsion in the short range.

description: The Iterative Born Approximation (IBA) is a well-known method for describing waves scattered by semi-transparent objects. In this paper, we present a novel nonlinear inverse scattering method that combines IBA with an edge-preserving total variation (TV) regularizer. The proposed method is obtained by relating iterations of IBA to layers of a feedforward neural network and developing a corresponding error backpropagation algorithm for efficiently estimating the permittivity of the object. Simulations illustrate that, by accounting for multiple scattering, the method successfully recovers the permittivity distribution where the traditional linear inverse scattering fails.
Macroeconomic Dynamics of Assets, Leverage and Trust

description: A macroeconomic model based on the economic variables (i) assets, (ii) leverage (defined as debt over asset) and (iii) trust (defined as the maximum sustainable leverage) is proposed to investigate the role of credit in the dynamics of economic growth, and how credit may be associated with both economic performance and confidence. Our first notable finding is the mechanism of reward/penalty associated with patience, as quantified by the return on assets. In regular economies where the EBITA/Assets ratio is larger than the cost of debt, starting with a trust higher than leverage results in the highest long-term return on assets (which can be seen as a proxy for economic growth). Our second main finding concerns a recommendation for the reaction of a central bank to an external shock that affects negatively the economic growth. We find that late policy intervention in the model economy results in the highest long-term return on assets and largest asset value. But this comes at the cost of suffering longer from the crisis until the intervention occurs. The phenomenon can be ascribed to the fact that postponing intervention allows trust to increase first, and it is most effective to intervene when trust is high. These results derive from two fundamental assumptions underlying our model: (a) trust tends to increase when it is above leverage; (b) economic agents learn optimally to adjust debt for a given level of trust and amount of assets. Using a Markov Switching Model for the EBITA/Assets ratio, we have successfully calibrated our model to the empirical data of the return on equity of the EURO STOXX 50 for the time period 2000-2013. We find that dynamics of leverage and trust can be highly non-monotonous with curved trajectories, as a result of the nonlinear coupling between the variables.

description: We present a catalog of 166 spectroscopically identified hot subdwarf stars from LAMOST DR1, 44 of which show the characteristics of cool companions in their optical spectra. Atmospheric parameters of 122 non-composite spectra subdwarf stars were measured by fitting the profiles of hydrogen (H) and helium (He) lines with synthetic spectra from non-LTE model atmospheres. Most of the sdB stars scatter near the Extreme Horizontal Branch in the $T_{\rm eff}-\log{g}$ diagram and two well defined groups can be outlined. A clustering of He-enriched sdO stars appears near $T_{\rm eff}=45\,000$ K and $\log(g) = 5.8$. The sdB population separates into several nearly parallel sequences in the $T_{\rm eff}-{\rm He}$ abundance diagram with clumps corresponding to those in the $T_{\rm eff}-\log{g}$ diagram. Over $38\,000$ K (sdO) stars show abundance extremes, they are either He-rich or He-deficient and we observe only a few stars in the $ -1 < \log(y) < 0$ abundance range. With increasing temperature these extremes become less prominent and the He abundance approaches to $\log(y)\sim-0.5$. A unique property of our sample is that it covers a large range in apparent magnitudes and galactic latitudes, therefore it contains a mix of stars from different populations and galactic environments. Our results are consistent with the findings of Hirsch (2009) and we conclude that He-rich and He-deficient sdB stars ($\log(y) < 1$) probably origin from different populations. We also find that most sdO and sdB stars lie in a narrow strip in the luminosity and helium abundance plane, which suggests that these atmospheric parameters are correlated.

description: We present well-sampled optical observations of the bright Type Ia supernova (SN~Ia) SN 2011fe in M101. Our data, starting from $\sim16$ days before maximum light and extending to $\sim463$ days after maximum, provide an unprecedented time series of spectra and photometry for a normal SN~Ia. Fitting the early-time rising light curve, we find that the luminosity evolution of SN 2011fe follows a $t^n$ law, with the index $n$ being close to 2.0 in the $VRI$ bands but slightly larger in the $U$ and $B$ bands. Combining the published ultraviolet (UV) and near-infrared (NIR) photometry, we derive the contribution of UV/NIR emission relative to the optical. SN 2011fe is found to have stronger UV emission and reaches its UV peak a few days earlier than other SNe~Ia with similar $Δm_{15}(B)$, suggestive of less trapping of high-energy photons in the ejecta. Moreover, the $U$-band light curve shows a notably faster decline at late phases ($t\approx 100$--300 days), which also suggests that the ejecta may be relatively transparent to UV photons. These results favor the notion that SN 2011fe might have a progenitor system with relatively lower metallicity. On the other hand, the early-phase spectra exhibit prominent high-velocity features (HVFs) of O~I $λ$7773 and the Ca~II~NIR triplet, but only barely detectable in Si~II~6355. This difference can be caused either by an ionization/temperature effect or an abundance enhancement scenario for the formation of HVFs; it suggests that the photospheric temperature of SN 2011fe is intrinsically low, perhaps owing to incomplete burning during the explosion of the white dwarf.

description: This paper summarizes 5 years of R&D efforts towards for the conception of PV module cooling
equipment that would be economically sound for retrofitting existing PV plants in temperate and tropical climates.
It is well established that cooling Si-based PV modules does increase their power output by ~0.45%/°K.
The initial objective of the research was to identify the most effective method to cool large arrays of modules:
the outcome was to maximize the evaporation of droplets of pure rainwater entering into contact with the solar glass
surface. The next objective was to devise a method that would optimize use of the water resources, (i.e. of rainwater
collected in the winter) and maximize the overall power output gains across the year. This resulted in connected
equipment driven by industrial algorithms, which continuously calculate 2 main factors: the “cooling opportunity”
and the “cooling cost”, thereby ensuring at any instant the financial viability of cooling the PV modules. The paper
shows the relationship between solar irradiation and power output and detailed comparative results obtained from the
all-year-long cooling of existing commercial-size PV plants in Europe.

description: The role of magnetic fields in galaxy evolution is still an unsolved question in astrophysics. We have previously shown that magnetic fields play a crucial role in major mergers between disc galaxies; in hydrodynamic simulations of such mergers, the Auriga model produces compact remnants with a distinctive bar and ring morphology. In contrast, in magnetohydrodynamic (MHD) simulations, remnants form radially-extended discs with prominent spiral arm structure. In this paper, we analyse a series of cosmological "zoom-in" simulations of major mergers and identify exactly \textit{how} magnetic fields are able to alter the outcome of the merger. We find that magnetic fields modify the transport of angular momentum, systematically hastening the merger progress. The impact of this altered transport depends on the orientation of the field, with a predominantly non-azimuthal (azimuthal) orientation increasing the central baryonic concentration (providing support against collapse). Both effects act to suppress an otherwise existent bar-instability, which in turn leads to a fundamentally different morphology and manifestation of feedback. We note, in particular, that stellar feedback is substantially less influential in MHD simulations, which allows for the later accretion of higher angular momentum gas and the subsequent rapid radial growth of the remnant disc. A corollary of the increased baryonic concentration in MHD simulations is that black holes are able to grow twice as large, although this turns out to have little impact on the remnant's development. Our results show that galaxy evolution cannot be modelled correctly without including magnetic fields.

description: The repowering of the exist ing PV plant Krempendorf I having an apparent power of 22.48 MVA (DC
peak power of 24.3 MWp), was carried out through the Krempendorf II extension with an apparent power of 7.84
MVA (DC peak power of 10.0 MWp). The following specific requirements had to be fulfilled: Since the grid
connect ion point was not updated, the apparent power of both plan ts had to be limited to 22.48 MVA. Due to
different feed-in tariffs, the old plant with a higher tariff had to be given priority while the plant extension had to
deliver power that whenever possible, did not exceed the apparent power limit . The implemented cont rol concept had
to avoid t ripping the overcurrent protect ion and, at the same t ime, maximize the product ion of the plant extension
(Krempendorf II). In order to fulfil these requirements a new cont rol feature had to be developed. In this paper the
methodology for developing this feature is presented, together with the results including real measurements.

description: In recent years the installed PV and wind capacity increased significantly. Due to the higher penetration of renewable
fluctuating energy sources in the local grid new challenges rose up and needed to be implemented by grid suppliers
and inverter manufacturers to maintain a stable grid. To avoid large over voltages and frequency fluctuations that
may cause total grid black-outs new advanced requirements were set for all inverter type system that feed power into
the grid. Those new requirements for the US are designed to regulate, operate and manage the local grid to keep it
stable and safe for all grid connected power consumers (e.g. avoid overvoltage that may damage electronic
appliances).
This will be important because of further increased penetration of renewable energies in certain areas in combination
with limited grid resources. Grid expansion is typically expensive and will take years and therefore is one of the last
options. With the help of smart and advanced features build into inverters more green energy can be feed-in while
allowing grid operators to more easily manage the grid.
Advanced inverter functions are defined (or are being developed) in international and national standards and will be
mandatory in the near future, if not already. The scope of those functions is to provide more flexibility for the grid to
enable more renewable energy sources to be connected to it while keeping the grid reliable. The new requirements
based on different local requirements and standards can be easily evaluated using the presented approach with an
automated test setup in combination of reduced time and cost.
The upcoming revision of UL 1741 includes new requirements, where new tests and functions are described to
stabilize and serve the public electrical grid and allow tailoring the function of the inverter depending on the need of
the public grid. A protocol like Sunspec allows the parameterization remotely and helps to speed the testing. The
possibility to manage and control inverters remotely will be of general importance. Most manufactures already
include some of those functions in their products. There reliability and interoperability has still to be proven and our
presented approach is designed to do so.

description: Biomedical optical imaging has a possibility of a comprehensive diagnosis of thyroid cancer in conjunction with ultrasound imaging. For improvement of the optical imaging, this study develops a higher order scheme for solving the time-dependent radiative transport equation (RTE) by use of the finite-difference and discrete-ordinate methods. The accuracy and efficiency of the developed scheme are examined by comparison with the analytical solutions of the RTE in homogeneous media. Then, the developed scheme is applied to describing photon migration in the human neck model. The numerical simulations show complex behaviors of photon migration in the human neck model due to multiple diffusive reflection near the trachea.

description: During late October 2014, active region NOAA 2192 caused an unusual high level of solar activity, within an otherwise weak solar cycle. While crossing the solar disk, during a period of 11 days, it was the source of 114 flares of GOES class C1.0 and larger, including 29 M- and 6 X-flares. Surprisingly, none of the major flares (GOES class M5.0 and larger) was accompanied by a coronal mass ejection, contrary to statistical tendencies found in the past. From modeling the coronal magnetic field of NOAA 2192 and its surrounding, we suspect that the cause of the confined character of the flares is the strong surrounding and overlying large-scale magnetic field. Furthermore, we find evidence for multiple magnetic reconnection processes within a single flare, during which electrons were accelerated to unusual high energies.

description: The use of solar energy especially for desalination of seawater and refrigeration is well adapted for the
Saharan region where the climate is extremely hot, the fresh water is scarce and solar energy potential is high. This
paper presents an innovative mechanism reflected in a combination of mechanical vapor compression (MVC)
desalination unit and absorption refrigeration machine (ARM) powered by solar Photovoltaic Thermal (PVT)
collectors. The idea consists to recover the heat generated by the condenser of cold production machine in order to
heat part of the intake seawater and improve the coefficient of performance (COP) of the (ARM). The PVT system
provides the electrical energy required by the compressor and thermal energy for cold production and/or to heat the
intake seawater. The proposed approach is illustrated using a case study for a typical summer day in the Dakhla city
sited at the south of Morocco by using the global model, which includes SOLAR-MVC-ARM models. The influence
of the combination on the power consumption and COP of MVC-ARM system powered by solar energy is studied.
The results demonstrate that the new system reduces the electric consumption of the compressor and improve the
COP of the ARM. Moreover, it is possible to operate the cycle at a low generator temperature. This study testifies that
the combining system is efficient compared to each separate systems.

description: Context. Comets are primitive objects, remnants of the volatile-rich planetesimals from which the solar system condensed. Knowing their structure and composition is thus crucial for the understanding of our origins. After the successful landing of Philae on the nucleus of 67P/Churyumov-Gerasimenko in November 2014, for the first time, the Rosetta mission provided the opportunity to measure the low frequency electrical properties of a cometary mantle with the permittivity probe SESAME-PP (Surface Electric Sounding and Acoustic Monitoring Experiment - Permittivity Probe). Aims. In this paper, we conduct an in-depth analysis of the data from active measurements collected by SESAME-PP at Abydos, which is the final landing site of Philae, to constrain the porosity and, to a lesser extent, the composition of the surface material down to a depth of about 1 meter. Methods. SESAME-PP observations on the surface are then analyzed by comparison with data acquired during the descent toward the nucleus and with numerical simulations that explore different possible attitudes and environments of Philae at Abydos using a method called the Capacity-Influence Matrix Method. Results. Reasonably assuming that the two receiving electrode channels have not drifted with respect to each other during the ten-year journey of the Rosetta probe to the comet, we constrain the dielectric constant of the first meter below the surface at Abydos to be > 2.45 p/m 0.20, which is consistent with a porosity < 50% if the dust phase is analogous to carbonaceous chondrites and < 75% in the case of less primitive ordinary chondrites. This indicates that the near surface of the nucleus of 67P/Churyumov-Gerasimenko nucleus is more compacted than its interior and suggests that it could consist of a sintered dust-ice layer.

description: The idea of integrating polygeneration system in hospitals came from the characteristic that healthcare
facilities require simultaneously different forms of energy (heat, steam, electricity and cooling) with the necessity of
permanently guaranteed availability of the energy throughout the year. Therefore, since Morocco expects to benefit
largely from solar energy, a solar polygeneration system applied for hospitals seems the adequate way to respond to
the National Energy Efficiency strategy launched by the Morocco’s Ministry of Health. The purpose of this paper is
to illustrate and examine energetic problematic faced by most hospitals in Morocco presented through a case study
of a 250-bed hospital, and to establish a configuration of a solar polygeneration system that will remedy energetic
concerns. The proposed system, consisting of both Concentrating Photovoltaic Thermal Systems (CPV/T) ,and
Combined Cooling, Heating and Power plant(CCHP), recovers the energy rejected by the overall CPV, incinerator
and boiler, in order to predict an optimal size of both CPV/T and CCHP plant which still require a considerable
investment. In addition, it will achieve greater energy efficiency, provide more comfort to patients and caregivers,
and reduce greenhouse gas emissions.

description: We review methods that allow one to detect and characterise quantum correlations in many-body systems, with a special focus on approaches which are scalable. Namely, those applicable to systems with many degrees of freedom, without requiring a number of measurements or computational resources to analyze the data that scale exponentially with the system size. We begin with introducing the concepts of quantum entanglement, Einstein-Podolsky-Rosen steering, and Bell nonlocality in the bipartite scenario, to then present their multipartite generalisation. We review recent progress on characterizing these quantum correlations from partial information on the system state, such as through data-driven methods or witnesses based on low-order moments of collective observables. We then review state-of-the-art experiments that demonstrated the preparation, manipulation and detection of highly-entangled many-body systems. For each platform (e.g. atoms, ions, photons, superconducting circuits) we illustrate the available toolbox for state preparation and measurement, emphasizing the challenges that each system poses. To conclude, we present a list of timely open problems in the field.

description: The integration of high shares of variable renewable energy sources is an aspect that is acquiring
importance as it can lead to integration problems. The three main options to achieve this task are the enlargement and
reinforcement of the grid, the use of storage devices, and demand side management. A modelling approach is applied
in this study to evaluate the maximum level of renewable energy integration for the Italian power system when adopting
electric storage. Firstly, the integration trend has been investigated starting from the production profile of variable
renewable energy sources. The results show that the optimal combination of wind and solar energy to maximize the
integration of renewables is 55% and 45%, respectively. Afterward, the impact of storage systems has been evaluated
in the case of high renewable energy penetration. An optimization approach is then applied to assess the best mix of
solar and wind energy while minimizing the costs. Results show that the best share of renewable energies stabilizes on

description: To identify the importance of and difficulty with valued activities in persons with systemic sclerosis (SSc) and to examine relationships between disease symptoms and difficulty with valued activities using the Valued Activities Scale (VLA). A secondary purpose was to examine the internal consistency of the Short-VLA Scale (S-VLA). A cross-sectional convenience sample of 99 people with SSc completed questionnaires regarding demographics, symptom severity, Health Assessment Questionnaire (HAQ), Center for Epidemiologic Studies Depression Scale (CES-D), and the VLA. Obligatory activities were rated as most important; committed activities were significantly more difficult than obligatory and discretionary. Less fatigue (p < 0.01) and lower HAQ (p < 0.001) and CES-D (p < 0.01) scores were associated with higher total VLA scores. Internal consistency of the S-VLA was excellent (Cronbach’s alpha = 0.92; p < 0.0001). The correlation between the S-VLA and the VLA was excellent (r = 0.96; p < 0.001). There were moderate correlations between the S-VLA and the HAQ (r = 0.73; p < 0.0001); the correlation with the CES-D was only fair (r = 0.35; p < 0.001). Committed and discretionary activities were more difficult for people with SSc to perform. Results are similar to findings with people with rheumatoid arthritis and systemic lupus erythematosus.IMPLICATIONS FOR REHABILITATIONHome management/caregiving (committed) and leisure and social participation (discretionary) activities are more difficult to perform by people with SSc compared to self-care (obligatory) activities.Our findings that difficulty scores on the VLA were associated with more fatigue and depression suggest the need for rehabilitation to reduce disability in people with SSc.The S-VLA may be a useful screening and monitoring tool for SSc and other chronic conditions.

description: The isoscalar monopole(ISM) and dipole(ISD) excitations in $^{12}$C are theoretically investigated with the shifted antisymmetrized molecular dynamics(AMD) plus $3α$-cluster generator coordinate method(GCM). The small amplitude vibration modes are described by coherent one-particle one-hole excitations expressed by small shift of single-nucleon Gaussian wave functions within the AMD framework, whereas the large amplitude cluster modes are incorporated by superposing $3α$-cluster wave functions in the GCM. The coupling of the excitations in the intrinsic frame with the rotation and parity transformation is taken into account microscopically by the angular-momentum and parity projections. The present calculation describes the ISM and ISD excitations in a wide energy region covering cluster modes in the low-energy region and the giant resonances in the high-energy region, though the quantitative description of the high-energy part is not satisfactory. The low-energy ISM and ISD strengths of the cluster modes are enhanced by the radial motion of $α$ clusters, and they split into a couple of states because of the angular motion of $α$ clusters. The low-energy ISM strengths exhaust 26% of the EWSR, which is consistent with the experimental data for the $^{12}$C($0^+_2$;7.65 MeV) and $^{12}$C($0^+_3$;10.3 MeV) measured by $(e,e')$, $(α,α')$, and ($^6$Li,$^6$Li$'$) scatterings. In the calculated low-energy ISD strengths, two $1^-$ states (the $1^-_1$ and $1^-_2$) with the significant strengths are obtained in $E=10-15$ MeV. It is indicated that the ISD excitations can be a good probe to experimentally search for new cluster states such as the $^{12}$C($1^-_2$) obtained in the present calculation.

description: The developing region of SAARC (South Asian Association for Regional Cooperation) is home to a large number of
people living below the poverty line. In future, providing affordable, access to all, reliable, low to zero carbon
electricity in this region will be the main aim of electricity generation. A cost optimal 100% renewable energy based
system is simulated for this region for the year 2030 on an hourly resolved basis for an entire year. The region was
divided into 16 sub-regions and three different scenarios were set up based on the level of high voltage direct current
(HVDC) grid connections. The results obtained for a total system levelised cost of electricity (LCOE) showed a
decrease from 71.6 €/MWh in a decentralized to 67.2 €/MWh for a centralized grid connected scenario. An additional
scenario was simulated to show the benefits of integrating industrial gas production and seawater reverse osmosis
desalination demand which was reflected as the system cost decreased by 5% and the total electricity generation
decreased by 1%. The results show that a 100% renewable energy based system could be a reality in the SAARC
region with the cost assumptions used in this research and it may be more cost competitive than the nuclear and fossil
carbon capture and storage (CCS) alternatives.

description: Accessing, controlling and understanding nanoscale friction and dissipation is a crucial issue in nanotechnology, where moving elements are central. Recently, ultra-sensitive noncontact pendulum Atomic Force Microscope (AFM) succeeded in detecting the electronic friction drop caused by the onset of superconductivity in Nb, raising hopes that a wider variety of mechanisms of mechanical dissipation arising from electron organization into different collective phenomena will become accessible through this unconventional surface probe. Among them, the driven phase dynamics of charge-density-waves (CDWs) represents an outstanding challenge as a source of dissipation. Here we report a striking multiplet of AFM dissipation peaks arising at nanometer distances above the surface of NbSe$_2$ - a layered compound exhibiting an incommensurate CDW. Each peak appears at a well defined tip-surface interaction force of the order of a nN, and persists until T=70K where CDW short-range order is known to disappear. A theoretical model is presented showing that the peaks are connected to tip-induced local 2$π$ CDW phase slips. Under the attractive potential of the approaching tip, the local CDW surface phase landscape deforms continuously until a series of 2$π$ jumps occur between different values of the local phase. As the tip oscillates to and fro, each slip gives rise to a hysteresis cycle, appearing at a selected distance, the dissipation corresponding to "pumping" in and out a local slip in the surface CDW phase of NbSe$_2$.

description: This exploratory case-controlled study examined whether the same amount of effort leads to similar feelings of fatigue and whether feelings of fatigue decline at the same rate in people with traumatic brain injury (pwTBI) compared to controls. Twenty pwTBI and 20 healthy controls (HC) completed an adaptive n-back task to induce fatigue and reported mental effort upon task completion and state-fatigue pre-task and several times during 30-minutes rest-period post-task. Task difficulty adapted to performance allowing both groups to invest substantial amounts of mental effort. Fatigue and effort levels were higher in pwTBI compared to controls. Multiple linear regression analyses showed that effort was positively related to post-task fatigue and this relationship did not differ between groups. Pre-task fatigue was the only predictor of post-task fatigue. Multilevel models showed no significant difference in decline of fatigue over the rest-period between groups. Excessive feelings of fatigue following TBI could not be explained by a higher vulnerability to the fatigue-inducing effects of mental effort needed to perform a specific task. In pwTBI pre-task fatigue levels might be more related to the complex demands of everyday life. Future studies should investigate recovery of fatigue and applications of this knowledge to rehabilitation interventions.Implications for rehabilitationPeople with TBI experience long-term fatigue as one of the most frequent and disabling symptoms and this long-term fatigue is a risk factor for development of secondary psychiatric symptoms such as depression or anxiety.Since people with TBI did not show a higher vulnerability to the fatigue-inducing effects of mental effort, fatigue following TBI might be better explained by the complex demands of everyday life such as external (environment) and internal (emotions) factors.Rehabilitation programs should be directed to this complex and highly individual interplay of fatigue in relation to other factors.

description: A major experimental program is presently underway to determine the Sivers, Boer-Mulders and transversity distributions, vital for understanding the internal structure of the nucleon. To this end we consider the Sivers, Boer-Mulders and transversity azimuthal asymmetries of the difference cross sections of hadrons with opposite charges in SIDIS reactions with unpolarized and transversely polarized target l+N\to l'+h+X, h=π^\pm, K^\pm, h^\pm. We show that on deuteron target these asymmetries are particularly simple and determine the sum of the valence-quark Q_V=u_V+d_V transverse momentum dependent distributions without any contributions from the strange or other sea-quark functions. At present, data on these asymmetries are presented for the integrated asymmetries i.e. the x_B- and z_h-dependent asymmetries. If data are available in small bins in Q^2, so that Q^2-dependence can be neglected, these expressions simplify dramatically leading to remarkably simple and powerful tests of the simplifying assumptions used in extracting these functions from the data.
