description: The phase diagram for the bond-interacting self-avoiding walk is calculated using transfer matrices on finite strips. The model is shown to have a richer phase diagram than the related $Θ$-point model. In addition to the standard collapse transition, we conjecture the existence of a line of transitions in the Berezinskii--Kosterlitz--Thouless (BKT) universality class, terminating in a critical end point. Our results are in contradiction with a previous transfer matrix calculation by Machado K D, de Oliveira M J and Stilck J F 2001 {\em Phys Rev E} {\bf 64} 051810.

description: As an extension of the weak perturbation theory obtained in recent analysis on infinite-derivative non-local non-Abelian gauge theories motivated from p-adic string field theory, and postulated as direction of UV-completion in 4-D Quantum Field Theory (QFT), here we investigate the confinement conditions and $β-$function in the strong coupling regime. We extend the confinement criterion, previously obtained by Kugo and Ojima for the local theory based on the Becchi-Rouet-Stora-Tyutin (BRST) invariance, to the non-local theory, by using a set of exact solutions of the corresponding local theory. We show that the infinite-derivatives which are active in the UV provides finite contributions also in the infrared (IR) limit and provide a proof of confinement, granted by the absence of the Landau pole. The main difference with the local case is that the IR fixed point is moved to infinity. We also show that in the limit of the energy scale of non-locality $M \rightarrow \infty$ we reproduce the local theory results and see how asymptotic freedom is properly recovered.

Year: 2017

description: Background: Drawing Archimedes spirals is a popular and valid method of assessing action tremor in the upper limbs. We performed the first blinded comparison of Fahn–Tolosa–Marín (FTM) ratings and tablet measures of essential tremor to determine if a digitizing tablet is better than 0–4 ratings in detecting changes in essential tremor that exceed random variability in tremor amplitude. Methods: The large and small spirals of FTM were drawn with each hand on two consecutive days by 14 men and four women (age 60±8.7 years [mean±SD]) with mild to severe essential tremor. The drawings were simultaneously digitized with a digitizing tablet. Tremor in each digitized drawing was computed with spectral analysis in an independent laboratory, blinded to the clinical ratings. The mean peak-to-peak tremor displacement (cm) in the four spirals and mean FTM ratings were compared statistically. Results: Test–retest intraclass correlations (ICCs) (two-way random single measures, absolute agreement) were excellent for the FTM ratings (ICC 0.90, 95% CI 0.76–0.96) and tablet (ICC 0.97, 95% CI 0.91–0.99). Log10 tremor amplitude (T) and FTM were strongly correlated (logT = αFTM + β, α≈0.6, β≈–1.27, r = 0.94). The minimum detectable change for the tablet and FTM were 51% and 67% of the initial assessment. Discussion: Digitizing tablets are much more precise than clinical ratings, but this advantage is mitigated by the natural variability in tremor. Nevertheless, the digitizing tablet is a robust method of quantifying tremor that can be used in lieu of or in combination with clinical ratings. Corrigendum published on May 3, 2018

Μελετήθηκαν 35 ασθενείς [13/35 οξεία βρουκέλλωση-ΟΒ, 22/35 χρόνια βρουκέλλωση-ΧΒ(12/22 υποτροπιάζουσα μορφή-ΧΒ1, 10/22 άτυπη μορφή-ΧΒ2)], 11 αποθεραπευθέντες και 15 μάρτυρες. Μετρήθηκαν με κυτταρομετρία ροής : οι CD3+, CD4+ και CD8+ T-λεμφοκυτταρικοί υποπληθυσμοί, η CD4/CD25(IL-2Ra) και CD4/CD28 συνέκφραση στα Τ-λεμφοκύτταρα, και η CD14/CD80(B7-1) συνέκφραση στα μονοκύτταρα/μακροφάγα. Οι μετρήσεις πραγματοποιήθηκαν (Α) ex vivo, (B) μετά από PHA-καλλιέργειες(in vitro διέγερση), απουσία αντιγόνου, και με την προσθήκη μη εδικού(Ε. coli LPS) και ειδικού (Β. abortus) της νόσου αντιγόνου. Συμπεράσματα. Στη ΧΒ, σε αντίθεση με την ΟΒ, διαπιστώθηκε σημαντικά ελαττωμένη, ex vivo και in vitro, έκφραση IL-2Ra στα CD4+ T-λεμφοκύτταρα και σημαντική in vitro αύξηση in vitro B7-1 έκφραση των CD8+ T-λεμφοκυττάρων. Στην ΟΒ και ΧΒ παρατηρήθηκε αυξημένη Β7-1 έκφραση μεταξύ των ΧΒ1 και ΧΒ2 υποομάδων της ΧΒ, που ενδεχομένως σχετίζεται με τη διαφορετική κλινική συμπεριφορά των ασθενών αυτών. Για την ανεργία στη ΧΒ, φαίνεται ότι ευθύνεται το παθογόνο, διότι η προσθήκη βρουκελλικού αντιγόνου, οδήγησε δε σημαντικά ελαττωμένη in vitro IL-2Ra και B7-1 έκφραση. Τέλος, οι αποθεραπευθέντες εμφάνιζαν παρόμοια με τους μάρτυρες αποτελέσματα
description: AIM. To investigate the role of B7/CD28 costimulation in the immune response against brucella and the outcome of brucellosis. Methods. 35 brucellosis patient[13/35 acute-AB, 22/35 chronic-CB(12/22 relapsing type-CB1, 10/22 atypical type-CB2)], 11 cured subjects and 15 healthy volunteers(controls) were studied. In all groups the following parameters were analyzed by flow cytometry both ex vivo (A), and after PHA-cultures(in vitro stimulation) without antigen, and with disease non specific(E. coli LPS) and disease specific(B. abortus) antigen (B) : a)CD3+, CD+ and CD8+ T-lymphocyte subsets, b)CD4/CD25 and CD4/CD28 co-expression on T-lymphocytes c)CD14/CD80 (B7-1) c0-expression on monocytes/macrophages. Conclusions. CB patients, in contrast to AB, characterized by significantly low ex vivo proportion of CD8+ T-lymphocytes. The macrophage B7-1 expression was significantly increased in both groups of patients. However, CB1 presented significantly higher B7-1 expression is possibly one qualitative parameter, which is related to the different clinical picture of CB1/CB2 subgroups. Brucella itself seems to be responsible for the anergy observed in CB patients, because the addition of brucella in all brucellosis leads to a significant blocking of IL-2Ra and B7-1 expression, in all brucellosis patients. Cures subjects shared similar results to controls in both ex vivo and in vitro analysis

description: The principal objective of this project is to investigate the gravitational lensing by asymptotically flat black holes in the framework of Horndeski theory in weak field limits. To achieve this objective, we utilize the Gauss-Bonnet theorem to the optical geometry of asymptotically flat black holes and apply the Gibbons-Werner technique to achieve the deflection angle of photons in weak field limits. Subsequently, we manifest the influence of plasma medium on deflection of photons by asymptotically flat black holes in the context of Horndeski theory. We also examine the graphical impact of deflection angle on asymptotically flat black holes in the background of Horndeski theory in plasma medium as well as non-plasma medium.

Rev. Lett. {\bf 97}, 167204 (2006)] suggesting the existence of a finite Dzyaloshinskii-Moriya interaction. We show that including such a spin anisotropy greatly improves the fit of the magnetization curve and gives the correct trend of the insofar unexplained anomalous behavior of the specific heat in magnetic field at low temperature.

description: Existing remote sensing change detection methods are heavily affected by seasonal variation. Since vegetation colors are different between winter and summer, such variations are inclined to be falsely detected as changes. In this letter, we proposed an image translation method to solve the problem. A style-based recalibration module is introduced to capture seasonal features effectively. Then, a new style discriminator is designed to improve the translation performance. The discriminator can not only produce a decision for the fake or real sample, but also return a style vector according to the channel-wise correlations. Extensive experiments are conducted on season-varying dataset. The experimental results show that the proposed method can effectively perform image translation, thereby consistently improving the season-varying image change detection performance.

description: Background: Blepharospasm can be present as an isolated dystonia or in conjunction with other forms of cranial dystonia, causing significant disability. Case Report: We report a case of a 69-year-old male with craniocervical dystonia, manifesting primarily as incapacitating blepharospasm refractory to medical treatments. He underwent bilateral globus pallidus (GP) deep brain stimulation (DBS) with complete resolution of his blepharospasm and sustained benefit at 12 months postoperatively. Discussion: This case illustrates successful treatment of blepharospasm with pallidal stimulation. GP-DBS should be considered a reasonable therapeutic option for intractable blepharospasm.

description: We theoretically investigate the threshold for the director reorientation from the homeotropic state to the hybrid homeotropic-planar state and vice versa in a cell filled with a flexoelectric nematic liquid crystal (NLC) subjected to an electric field. The liquid crystal is doped by a CTAB-like substance, a part of molecules of which dissociates into positive and negative ions. The anchoring on one of the cell surfaces is assumed to be strong and homeotropic, while the other surface can adsorb positive ions which play the role of an orienting surfactant for NLC molecules on this surface. At certain voltages, the orientational transitions in the bulk of the NLC are possible due to the changing conditions for the director on the adsorbing surface. We calculate respective threshold voltages as functions of anchoring parameters. The existence of the critical values of these parameters, beyond which the orientational transitions do not take place, is established.

description: Forest reserves play an important role in the provision of ecosystem goods and services; however, these reserves are facing increasing anthropogenic impacts primarily because of agricultural activities. In sub-Saharan Africa, studies on understanding the extent and impacts of agricultural expansion into forest reserves are generally lacking. Thus, this study aimed to assess the extent of agricultural expansion into forest reserves in Zambia on a national scale between 2000 and 2018 and explores the drivers. We used a remote sensing approach by employing Google Earth Engine (GEE) and Random Forests classifier to map land cover changes at five-time steps: 2000, 2005, 2010, 2015 and 2018. Landsat images were used to map six land cover classes (forest, cropland, wetland, grassland, settlement, and water body) determined by the Intergovernmental Panel on Climate Change (IPCC). A social survey was also undertaken to understand the drivers of agricultural expansion into forest reserves at two study sited located in eastern and north-western part of Zambia. Based on the land cover maps which were produced with high accuracies ranging from 82% to 94%, the results indicated a general decline of 10% in forest area and an increase of 25% in cropland. Almost 50% of the forest reserves in Zambia are experiencing some form of encroachment, and 10% of these are heavily encroached (>90% loss). Local communities indicated that population growth, loss of soil fertility, high market demand for crops, land tenure system, and lack of law enforcement are the major drivers of agricultural expansion into forest reserves. This study highlights the need for policy marker to consider trade-offs in agricultural expansion and conservation of forest reserves relation to population growth. Enhancing sustainable agricultural practices and strengthening the implementation of different legislative frameworks is key in addressing the challenges of conservation, while enhancing food security.

Phenomenology Shown: A 41-year-old male with ChAc (confirmed by VPS13A mutations) reported that his involuntary axial movements were significantly ameliorated by either folding his arms over his chest or putting his hands behind his head. Educational Value: These apparent “sensory tricks” suggest a dystonic pathophysiology, and also merit further study to analyze their potential for symptom control in ChAc.

description: Coastal wetlands are predicted to undergo extensive transformation due to climate and land use change. Baseline maps of coastal wetlands can be used to help assess changes. Found in the upper portion of the estuarine zone, high marsh and salt pannes/flats provide ecosystem goods and services and are particularly important to fish and wildlife. We developed the first map of high marsh and salt pannes/flats along the northern Gulf of Mexico using regional models that included spectral indices related to greenness and wetness from optical satellite imagery, elevation data, irregularly flooded wetland probability information, and synthetic aperture radar backscatter. We found the greatest relative coverage of high marsh along the Texas coast (30% to 65%) and the Florida Panhandle (40%), whereas the greatest relative coverage of salt pannes/flats was along the lower Texas coast (74%) and the middle Texas coast (15%). As part of this effort, we also developed a map that highlighted irregularly flooded wetlands dominated by Juncus roemerianus (black needlerush) for part of the study area. Both maps had an overall accuracy of around 80%. Our results advance the understanding of estuarine marsh zonation and provide a baseline for assessing future transformations. This is the first map of high marsh and salt pannes/flats along the northern Gulf of Mexico and provides a baseline for understanding transformations predicted to occur with climate change. Due to high elevation uncertainty in wetlands, we used a map of irregularly flooded wetland probability that was created using elevation error assumptions. Irregularly flooded wetland probability, synthetic aperture radar backscatter, and spectral indices related to greenness and wetness were important predictor variables. Differences in wetland zonation and species composition along the study area led to variation in models by region. The framework presented here could be adapted to other areas.

description: In this paper we consider cosmological scaling solutions in general relativity coupled to scalar fields with a non-trivial moduli space metric. We discover that the scaling property of the cosmology is synonymous with the scalar fields tracing out a particular class of geodesics in moduli space - those which are constructed as integral curves of the gradient of the log of the potential. Given a generic scalar potential we explicitly construct a moduli metric that allows scaling solutions, and we show the converse - how one can construct a potential that allows scaling once the moduli metric is known.

description: A thermodynamic and transport study of Sr4Ru3O10 as a function of temperature and magnetic field is presented. The central results include a growing specific heat C with increasing field B, a magnetic contribution to C/T at low temperatures proportional to -log(T), an abrupt jump and a peak in C/T at 2.90 T and 7 T for B||ab-plane and B||c-axis, respectively, and corresponding changes in the low T power laws of the resistivity. The novelty of this work lies in the fact that this system is strongly anisotropic displaying spontaneous ferromagnetism along the c-axis and an intralayer metamagnetic transition with a possibility of a nearby quantum critical point. The exotic behavior reflects new physics that is yet to be understood.

description: Background: The aim of this study was to determine whether tremor and bradykinesia impacted a dexterous activity performed by patients with essential tremor (ET). Methods: Core bradykinesia was assessed in 27 controls and 15 patients with ET using a rapid alternating movement (RAM) task. Then, participants performed a “counting money” counting tasks while equipped with inertial measurement units to detect and quantify tremor during movement. The time required to perform subsections of the tasks and the rate of failure (errors) were compared between groups using Mann–Whitney U tests and a chi-square test, respectively. Results: Patients with ET presented with significant bradykinesia during the RAM task and had more tremor during the counting money task. However, the time required to perform the task and rate of failure were similar between groups. Discussion: Results show that even though bradykinesia was detected during fast movements, and that tremor was present during a task requiring dexterity, both symptoms did not interfere with the performance of patients with ET. This pilot study suggests that there may be a threshold at which tremor will become problematic. Determining this threshold for a wide range of daily activities may help determine when it is appropriate to initiate treatment for patients with ET.

description: We present the study of dynamical status of the globular cluster NGC 1851. A combination of multiwavelength space and ground-based data sets are used for the present analysis. In order to select the genuine cluster members, we used the astro-photometric data available from HST and GAIA-DR2 catalogs. The BSS radial distribution of the cluster is plotted from the center of the cluster to the outskirts. The radial distribution of BSS shows a central peak, followed by a dip at the intermediate radii (rmin ~ 90'') and a rising trend in the outskirts. We also estimated A+rh parameter as 0.391 +/- 0.006 to validate the findings of the radial distribution study. On the basis of the minima in the BSS radial distribution and the value of A+rh parameter, we conclude that NGC 1851 belongs to Family II classification and is an intermediate dynamical state cluster.

description: Background: The aim was to assess incidence, prevalence and risk factors of medication-induced tremor in African-Caribbean patients with severe mental illness (SMI). Method: A prospective study of SMI patients receiving care from the only mental health service of the previous Dutch Antilles. Eight clinical assessments, over 18 years, focused on movement disorders, medication use, and resting tremor (RT) and (postural) action tremor (AT). Risk factors were modeled with logistic regression for both current (having) tremor and for tremor at the next time point (developing). The latter used a time-lagged design to assess medication changes prior to a change in tremor state. Results: Yearly tremor incidence rate was 2.9% and mean tremor point prevalence was 18.4%. Over a third of patients displayed tremor during the study. Of the patients, 5.2% had AT with 25% of cases persisting to the next time point, while 17.1% of patients had RT of which 65.3% persisted. When tremor data were examined in individual patients, they often had periods of tremor interspersed with periods of no tremor. Having RT was associated with age (OR = 1.07 per year; 95% confidence interval 1.03–1.11), sex (OR = 0.17 for males; 0.05–0.78), cocaine use (OR = 10.53; 2.22–49.94), dyskinesia (OR = 0.90; 0.83–0.97), and bradykinesia (OR = 1.16; 1.09–1.22). Developing RT was strongly associated with previous measurement RT (OR = 9.86; 3.80–25.63), with previous RT severity (OR = 1.22; 1.05–1.41), and higher anticholinergic load (OR = 1.24; 1.08–1.43). Having AT was associated with tremor-inducing medication (OR = 4.54; 1.90–10.86), cocaine use (OR = 14.04; 2.38–82.96), and bradykinesia (OR = 1.07; 1.01–1.15). Developing AT was associated with, previous AT severity (OR = 2.62 per unit; 1.64–4.18) and tremor reducing medication (OR = 0.08; 0.01–0.55). Conclusions: Long-stay SMI patients are prone to developing tremors, which show a relapsing–remitting course. Differentiation between RT and AT is important as risk factors differ and they require different prevention and treatment strategies.

description: We present the discovery of CWISE J203546.35-493611.0, a peculiar M8 companion to the M4.5 star APMPM J2036-4936 discovered through the citizen science project Backyard Worlds: Planet 9. Given CWISE J203546.35-493611.0's proper motion ($μ_α$, $μ_δ$) = ($-$126$\pm$22, $-$478$\pm$23) and angular separation of 34.2$''$ from APMPM 2036-4936, we calculate a chance alignment probability of $1.15 \times 10^{-6}$. Both stars in this system appear to be underluminous, and the spectrum obtained for CWISE J203546.35-493611.0 shows a triangular H band. Further study of this system is warranted to understand these peculiarities.

description: Many online platforms are providing valuable real-time contents (e.g., traffic) by continuously acquiring the status of different Points of Interest (PoIs). In status acquisition, it is challenging to determine how frequently a PoI should upload its status to a platform, since they are self-interested with private and possibly time-varying preferences. This paper considers a general multi-period status acquisition system, aiming to maximize the aggregate social welfare and ensure the platform freshness. The freshness is measured by a metric termed age of information. For this goal, we devise a long-term decomposition (LtD) mechanism to resolve the time-varying information asymmetry. The key idea is to construct a virtual social welfare that only depends on the current private information, and then decompose the per-period operation into multiple distributed bidding problems for the PoIs and platforms. The LtD mechanism enables the platforms to achieve a tunable trade-off between payoff maximization and freshness conditions. Moreover, the LtD mechanism retains the same social performance compared to the benchmark with symmetric information and asymptotically ensures the platform freshness conditions. Numerical results based on real-world data show that when the platforms pay more attention to payoff maximization, each PoI still obtains a non-negative payoff in the long-term.

description: In this thesis we study the deformation regime of thin plates, made by by functionally graded materials with viscoplastic or thermoviscoplastic properties, under biaxial loading. We are interested in examining the possible instability modes that can appear, characterized by strain localization. More specifically, we study the emergence of multiple necking under special conditions, and we also examine problems of shear banding appearance. Moreover, we introduce a type homogenization of functionally graded viscoplastic materials. The determination of the instability and numerically with the usage of finite element method. The conclusions of this thesis are : a0the appearance of multiple instability(necking, wrinkle, thinning and thickening), due to the combination of the graded material properties and the type of loading, and b)the sensitivity of hormogenization with respect to the initial boundary conditions

description: We consider transport properties of the hypernuclear matter in neutron star cores. In particular, we calculate the thermal conductivity, the shear viscosity, and the momentum transfer rates for np$Σ^{-}Λeμ$ composition of dense matter in $β$--equilibrium for baryon number densities in the range $0.1-1$~fm$^{-3}$. The calculations are based on baryon interactions treated within the framework of the non-relativistic Brueckner-Hartree-Fock theory. Bare nucleon-nucleon (NN) interactions are described by the Argonne v18 phenomenological potential supplemented with the Urbana IX three-nucleon force. Nucleon-hyperon (NY) and hyperon-hyperon (YY) interactions are based on the \new{NSC97e and NSC97a models} of the Nijmegen group. We find that the baryon contribution to transport coefficients is dominated by the neutron one as in the case of neutron star cores containing only nucleons. In particular, we find that neutrons dominate the total thermal conductivity over the whole range of densities explored and that, due to the onset of $Σ^-$ which leads to the deleptonization of the neutron star core, they dominate also the shear viscosity in the high density region, in contrast with the pure nucleonic case where the lepton contribution is always the dominant one.

description: Identifying some criteria to generalize the results of a research project on the Circular Economy on a European scale requires a
 broader competence on products end of life products combined with an ability to predict which will be the most relevant trend lines
 that will influence the technologies and economic dynamics of products end of life in the coming years.
 This deliverable highlights that there various types of criteria: some are of a general nature, cross-cutting and allow the project to be
 strengthened in terms of its European value, while others are more specific and expendable on the three specific value chains1 that,
 by integrating them, have surely more chances to be recognized and appreciated in European terms.
 The work is not limited to a mere statement of general criteria, but also provides some examples and operating suggestions for the
 transformation of these European criteria for valid operational suggestions for future activities of CarE-Service project.

description: The accurate characterization of carbonate rocks is crucial for determining the potential for exploring outcrops in the oil industry. Modern remote sensing instruments have played an important role in estimating mineral characteristics in the most varied scales. However, mathematical expressions suggested for converting radiance values to mineral information are often designed to work in only one particular territory. At the same time, the few general solutions existing tend to achieve overall poor results. In this paper, we propose an adaptive approach to estimate subpixel amounts of carbonate rocks using OLI-Landsat 8 image data. The main formulation is derived from exhaustive analysis of the spectral behavior of several carbonate materials. The formulation is subsequently adapted through the use of a genetic algorithm to work on diverse situations. Experiments have demonstrated the adaptability of the method for different environments, as well as its higher performance when compared with existing carbonate indices.
Spherical accretion in giant elliptical galaxies: multi-transonicity, shocks, and implications on AGN feedback

description: Isolated massive elliptical galaxies, or that are present at the center of cool-core clusters, are believed to be powered by hot gas accretion directly from their surrounding hot X-ray emitting gaseous medium. This leads to a giant Bondi-type spherical/quasi-spherical accretion flow onto their host SMBHs, with the accretion flow region extending well beyond the Bondi radius. In this work, we present a detailed study of Bondi-type spherical flow in the context of these massive ellipticals by incorporating the effect of entire gravitational potential of the host galaxy in the presence of cosmological constant $Λ$, considering a five-component galactic system (SMBH + stellar + dark matter + hot gas + $Λ$). The current work is an extension of Ghosh \& Banik (2015), who studied only the cosmological aspect of the problem. The galactic contribution to the potential renders the (adiabatic) spherical flow to become {\it multi-transonic} in nature, with the flow topology and flow structure significantly deviating from that of classical Bondi solution. More notably, corresponding to moderate to higher values of galactic mass-to-light ratios, we obtain Rankine-Hugoniot shocks in spherical wind flows. Galactic potential enhances the Bondi accretion rate. Our study reveals that there is a strict lower limit of ambient temperature below which no Bondi accretion can be triggered; which is as high as $\sim 9 \times 10^6 \, K$ for flows from hot ISM-phase, indicating that the hot phase tightly regulates the fueling of host nucleus. Our findings may have wider implications, particularly in the context of outflow/jet dynamics, and radio-AGN feedback, associated with these massive galaxies in the contemporary Universe.

description: Background: Post-hypoxic myoclonus (PHM) is a syndrome that occurs when a patient has suffered hypoxic brain injury. The myoclonus is usually multifocal and generalized, often stemming from both cortical and subcortical origins. In severe cases, pharmacological treatments with antiepileptic medications may not satisfactorily control the myoclonus. Methods: We present a case of a 23-year-old male with chronic medication refractory PHM following a cardiopulmonary arrest related to an asthmatic attack who improved with bilateral globus pallidus internus (GPi) deep brain stimulation (DBS). We review the clinical features of PHM, as well as the preoperative and postoperative Unified Myoclonus Rating Scale scores and DBS programming parameters in this patient and compare them with the three other published PHM-DBS cases in the literature. Results: This patient experienced an alleviation of myoclonic jerks at rest and a 39% reduction in action myoclonus with improvement in both positive and negative myoclonus with bilateral GPi-DBS. High frequency stimulation (130 Hz) with amplitudes >2.5 V were needed for the therapeutic response. Discussion: We demonstrate a robust improvement in a medication refractory PHM patient with bilateral GPi-DBS, and suggest that it is a viable therapeutic option for debilitating post-hypoxic myoclonus.

description: The purpose of this experiment was to study renal dusfunction during abdominal compartment syndrome with the method of tissue oximetry. Eight non-breed dog's were used. All animals were anesthetized and mechanically ventilated. Respiratory and hemodynamic parameters were measured throughout the procedure. To increase intra-abdominal pressure a special cannula was placed in the cortex of the kidney. All parameters were recorded at the starting point, with intra-abdominal pressure 15 and 30 nnHg and after pressure had returned to its normal values. We make the conclusion that renal tissue oxygenation is significantly reduced when intra-abdominal pressure is increased and return to normal after abdominal decompression

description: The equations of motion for matter fields are invariant under the shift of the matter lagrangian by a constant. Such a shift changes the energy momentum tensor of matter by T^a_b --> T^a_b +ρδ^a_b. In the conventional approach, gravity breaks this symmetry and the gravitational field equations are not invariant under such a shift of the energy momentum tensor. I argue that until this symmetry is restored, one cannot obtain a satisfactory solution to the cosmological constant problem. I describe an alternative perspective to gravity in which the gravitational field equations are [G_{ab} -κT_{ab}] n^an^b =0 for all null vectors n^a. This is obviously invariant under the change T^a_b --> T^a_b +ρδ^a_b and restores the symmetry under shifting the matter lagrangian by a constant. These equations are equivalent to G_{ab} = κT_{ab} + Cg_{ab} where C is now an integration constant so that the role of the cosmological constant is very different in this approach. The cosmological constant now arises as an integration constant, somewhat like the mass M in the Schwarzschild metric, the value of which can be chosen depending on the physical context. These equations can be obtained from a variational principle which uses the null surfaces of spacetime as local Rindler horizons and can be given a thermodynamic interpretation. This approach turns out to be quite general and can encompass even the higher order corrections to Einstein's gravity and suggests a principle to determine the form of these corrections in a systematic manner.
