Maksymilian Dryja and Krzysztof Moszyński (Warszawa) ON JEFFREYS MODEL OF HEAT CONDUCTION

The Jeffreys model of heat conduction is a system of two partial differential equations of mixed hyperbolic and parabolic character. The analysis of an initial-boundary value problem for this system is given. Existence and uniqueness of a weak solution of the problem under very weak regularity assumptions on the data is proved. A finite difference approximation of this problem is discussed as well. Stability and convergence of the discrete problem are proved. 0. Introduction. The Jeffreys model of heat conduction has recently been discussed by several authors [2], [5]–[7]. Its equations may be written in the following general form [5]: (0.1) Tt + div(Q) = 0, Qt +D∇T +Q− κ∆Q = 0. Here D and κ are positive (in general constant) coefficients, the scalar function T is the temperature, and the vector-valued function Q represents the so-called heat flux . We are interested in application of the one-dimensional Jeffreys model to describe heat waves in a thin metallic layer under a very short laser impulse [5]. Generalizations to more space dimensions are certainly possible and do not seem to be very difficult. Let us discuss the initial-boundary value problem for the one-dimensional Jeffreys model in the form appearing in [5]. We are looking for two scalar functions T = T (t, x) and Q = Q(t, x), subject to the following equations: (0.2) Tt +Qx = 0, Qt +DTx +Q− κQxx =

Classical statistical inference for coefficient alpha is well developed. This paper presents two methods for Bayesian statistical inference for a single sample alpha coefficient. An approximate analytic method based on conjugate distributions is derived. This method is easy to compute. A second method uses Markov Chain Monte Carlo (MCMC) methodology as implemented by the computer program WinBUGS. WinBUGS may be downloaded for free from the Internet, and this paper includes WinBUGS code for making Bayesian inferences about coefficient alpha. Pseudo-randomly generated data are used to compare the two Bayesian methods to each other and both of these methods to the classical method. The results indicate that the two Bayesian methods work well as long as the number of items and examinees are not too small. Appendixes discuss the derivation of the marginal likelihood, contain WinBUGS code, and present the figures. (Contains 1 table, 9 figures, and 11 references.)

Motivation in the Perspective of Self Determination Theory (SDT) between Work Environment and Job Satisfaction in Banking Sector

The expansion of business, fulfillments of demands and profits maximization have created stress and less motivation for job satisfaction. To fulfill the demand of organizations and maximize the satisfaction level of employees; the extrinsic and intrinsic motivation beyond psychological motivation has been used in this study to minimize stress level and maximize the satisfaction level among employees. This study explains work stress, job overload; performance pressure and job satisfaction while in motivation; the extrinsic/intrinsic factors of Self Determination Theory (SDT) have been used. Structured questionnaires were used to collect the data. The total distribution was 120 and response rate was 75 percent. The results found that work stress, job overload and performance pressure has negative impact on job satisfaction and employees do not like stress caused by work overload or job overload, while motivation factor has played an important psychological role in the study.
Characterization of the fertilization independent endosperm (FIE) gene from soybean

Reproduction of angiosperm plants initiates from two fertilization events: an egg fusing with a sperm to form an embryo and a second sperm fusing with the central cell to generate an endosperm. The tryptophan-aspartate (WD) domain polycomb protein encoded by fertilization independent endosperm (FIE) gene, has been known as a repressor of hemeotic genes by interacting with other polycomb proteins, and suppresses endosperm development until fertilization. In this study, one Glycine max FIE (GmFIE) gene was cloned and its expression in different tissues, under cold and drought treatments, was analyzed using both bioinformatics and experimental methods. GmFIE showed high expression in reproductive tissues and was responsive to stress treatments, especially induced by cold. GmFIE overexpression lines of transgenic Arabidopsis were generated and analyzed. Delayed flowering was observed from most transgenic lines compared to that of wild type. Overexpression of GmFIE in Arabidopsis also leads to semi-fertile of the plants.
Formation and Maintenance of Nocturnal Low-Level Stratus over the Southern West African Monsoon Region during AMMA 2006

AbstractThe southern parts of West Africa are frequently covered by an extensive deck of shallow, low (200–400 m AGL) stratus or stratocumulus clouds during the summer monsoon. These clouds usually form at night in association with a nocturnal low-level jet (NLLJ) and can persist into the early afternoon hours. Recent work suggests that the stratus deck is unsatisfactorily represented in standard satellite retrievals and state-of-the-art climate models. Here the authors use high-resolution regional simulations with the Weather Research and Forecasting Model (WRF) and observations from the African Monsoon Multidisciplinary Analysis (AMMA) 2006 campaign to investigate (i) the spatiotemporal distribution, (ii) the influence on the shortwave radiation balance, and (iii) the detailed formation and maintenance mechanisms of the stratiform clouds. At least some configurations of WRF satisfactorily reproduce the diurnal cycle of the low-cloud evolution, yielding the following main conclusions: (i) The simulated s.
Controlled Noise Seismology

We use controlled noise seismology (CNS) to generate surface waves, where we continuously record seismic data while generating artificial noise along the profile line. To generate the CNS data we drove a vehicle around the geophone line and continuously recorded the generated noise. The recorded data set is then correlated over different time windows and the correlograms are stacked together to generate the surface waves. The virtual shot gathers reveal surface waves with moveout velocities that closely approximate those from active source shot gathers.
A well-balanced reconstruction for wetting/drying fronts

A good numerical method for the Saint-Venant system of shallow water equations must be well-balanced in the sense that the method should exactly preserve \lake at rest" steady states. There are many numerical methods capable of achieving this goal, but only in the case of submerged bottom topography. When dry areas (island, shores) are contained in the computa- tional domain, most of well-balanced schemes fail to preserve \lake at rest" steady states unless the computational grid is adjusted to the wetting/drying fronts. This diculty can be overcome using a special reconstruction, which is presented in this paper. The proposed reconstruction is conservative, well-balanced and positivity preserving. We realize the new reconstruction in the framework of the second-order semi-discrete central-upwind scheme from (A. Kurganov and G. Petrova, Commun. Math. Sci., 2007). The positivity of the computed water height is ensured following (A. Bollermann, S. Noelle and M. Luk a cov a, Commun. Comput. Phys., 2010): The outgoing uxes are limited in case of draining cells.
Target ed radionuclide therapy for patients with neuroendocrine tumours

Targeted radionuclide therapy with Lu-DOTATATE for patients with neuroendocrine tumours utilises the frequent overexpressing of somatostatin receptors on the tumour cells. This treatment modality has demonstrated valuable patient benefits and is well tolerated. However, renal and bone marrow toxicity can become dose limiting and persisting. The aim of this thesis was to investigate normal tissue response during Lu-DOTATATE treatment, with focus on kidneys, bone marrow and also the spleen, the organ that receives the highest absorbed dose. To enable analysis of bone marrow response to absorbed dose, a novel image-based method for bone marrow dosimetry was developed. The first paper included, was a pre-clinical study of morphological and biochemical renal changes in nude mice injected with Lu-, or Y-DOTATATE. The remaining three studies evaluated 51 patients with neuroendocrine tumours, treated with LuDOTATATE at Sahlgrenska University Hospital. Patient renal and bone marrow function was evaluated and dosimetry was performed for kidneys, bone marrow and spleen utilising planar and SPECT images acquired after infusion, and the developed automated segmentation method for bone marrow dosimetry. Selective morphological changes were quantified in renal cortex of nude mice, and corresponding biochemical changes observed, after Lu-DOTATATE injection. These appeared in a dose-dependent manner. No morphological changes were observed for the animals receiving Y-DOTATATE. In the clinical studies, it was found that patients with inferior renal function were exposed to higher mean absorbed renal doses, and experienced enhanced haematological toxicity. It was also shown that a longer residence time for Lu and a higher tumour burden increased the haematological toxicity. A novel image-based method for bone marrow dosimetry was developed, and correlations were found between mean and total absorbed bone marrow doses, and haematological toxicity. The role of the spleen for haematological toxicity was also analysed, and it was observed that radiation exposure of the spleen had an impact on the haematological response. The results in this thesis emphasise that several parameters affects normal tissue response in LuDOTATATE treatment. Hopefully, a better understanding of what decides the individual response, may contribute to individualised treatment decisions in the
TAMAÑO DE LA POBLACIÓN MICROBIANA DEL SUELO Y DESARROLLO INICIAL DE Desmanthus virgatus (L.) Willd MICROBIAL SIZE POPULATION AND EARLY GROWTH OF Desmanthus virgatus (L.) Willd

Desmanthus virgatus (huizachillo) is a legume forage plant which shows excellent growth in Northeastern Mexico and has an important economical potential in this region, mainly in alkaline soils. Under greenhouse conditions the effect of microbial size population on the early growth of this legume, was studied in diluted up to 4 -9 and undiluted soil, particularly diazotrophic bacteria and mycorrhizal fungi. Infective propagules were quantified by the “Most Probable Number” technique and biomass was evaluated by its dry weight. The results showed a significant effect of the microbial population size on both aerial and root biomass. Aerial and root biomass of plants growing in intact soil was 11.1 and 5.5 times higher than that of plants growing in diluted soil (4 -6 to 4 -9 ), where no nodules nor mycorrhizae were found. The means comparison test (Tukey) generated three groups of plants: those growing with both symbionts (nitrogen fixing bacteria and mycorrhizal fungi), plants growing with only one symbiont (mycorrhizal fungi) and plants without endosymbionts. Our results indicate that growth of this plant is positively related to its ability for association to endosymbiotic microorganisms.
Vibrational and DFT Studies of Creatinine and Its Metal Complexes

Article history: Creatinine (2-amino-1-methyl-5H-imidazol-4-one) is an amino acid that occurs in vertebrate tissues and in urine. The mid and far infrared spectra of creatinine were recorded in the solid phase. The optimized structure of creatinine was obtained using DFT/B3LYP method with 6-311+G(d,p) and LANL2DZ basis sets. The harmonic frequencies of creatinine were calculated using DFT/B3LYP/6-311+G(d,p) method. The complete assignments were performed on the basis of the total energy distribution (TED) of the vibrational modes, calculated with scaled quantum mechanics (SQM) method. The creatinine-metal {cadmium (Cd(II)), zinc (Zn(II)) and mercury (Hg(II))} halogen (chloride (Cl - ) and bromide (Br - )) complexes were synthesized. DFT calculations, DFT-B3LYP/LANL2DZ were performed for the determination of geometrical structure and vibrational assignment for metal- complexes.
Kinematic and three-dimensional dynamic modeling of a biped robot

This article focuses on inverse kinematic formulation and dynamic modeling of the Nao biped robot's lower body, accompanied by verification with the joints' angles as experimental data. Dynamic modeling in two different planes is discussed and joint angles for the given positions, nominal conditions, and trajectory computations are simulated and graphically illustrated. A new approach for development of the inverse dynamics on the aforementioned robot's lower body is proposed in this paper, analytically studied, and compared with MSC Adams for two various scenarios of fixed supporting leg and ground contact implementation.
Functional outcome of single periarticular injection of steroid at shoulder for Periarthritis of shoulder – A prospective study

Introduction: Adhesive capsulitis (frozen shoulder) affects 2% to 5% of the adult population. The accuracy rate of intraarticular injections at shoulder was 52.4% in a study by Hegedus et al. Periarticular placement may allow sufficient steroid to diffuse into an adjacent joint and so achieve a partial response. Issues that remain to be clarified include whether the accuracy of needle placement and anatomical site influences efficacy. Due to these uncertainties we decided to do this study. Materials and Methods: A Prospective study analyzing the functional outcome of 34 cases of Single Periarticular injection of Steroid at Shoulder for Periarthritis of shoulder was conducted. The surgeon confirmed with C-arm image that the needle was periarticular and ‘not intraarticular’ and instilled the injection of 40 mg of Triamcinolone acetate. Findings were recorded and Outcomes were measured before the injection and during all the followups. Statistical Evaluation was made and Conclusions were arrived at. Results: There were 34 patients (36 shoulders) treated with periarticular injection of steroid. The improvement in abduction was 38.11 degrees with p value 0.001, which is statistically significant. Improvement in flexion was 39.19 degrees. The improvement in Constant score was 21.22 with p value 0.001 which is statistically significant. Conclusion: A single Periarticular injection of steroid for Periarthritis of shoulder provides good improvement in Abduction and Flexion. Its results are the same as with intraarticular injections. Blind injections without fluoroscopic guidance will give the same results as those with fluoroscopic guidance.
Genes associated with hypersensitive response (HR) in the citrus EST database (CitEST)

Plants are continuously exposed to pathogen attack, but successful infection is rare because they protect themselves against pathogens using a wide range of response mechanisms. One of them is the hypersensitive response (HR), which is a form of cell death often associated with plant resistance to pathogen infection to prevent the spreadsebpg@cnpq.br sebpg@cnpq.br of the potential pathogen from infected to uninfected tissues. Cell death is activated by recognition of pathogen-derived molecules by the resistance (R) gene products, and is associated with the massive accumulation of reactive oxygen species (ROS), salicylic acid (SA), and other pro-death signals such as nitric oxide (NO). The analysis of the citrus EST (CitEST) database revealed the presence of putative genes likely to be involved in HR through their products, like metacaspases, lipoxygenases, phospholipases, pathogenesis-related proteins, glutathione transferases/peroxidases, enzymes involved in the phenylpropanoid pathway and in the formation and detoxification of ROS, as well as those involved in the formation and regulation of ion channels, SA and NO. By analysis of the EST database of Citrus, it was possible to identify several putative genes that code for key enzymes involved in HR triggering and also in plant defense against biotic and abiotic stress.

Measuring Emotional Responses to TV Commercials: The Warmth Monitor Modernized

Recently there has been a lot of interest in measuring emotional responses to advertising. This study focuses on the measurement of a specific emotional response to television advertising; warmth. Nearly thirty years ago, (Aaker, Stayman and Hagerty, 1986) developed a procedure they called the Warmth Monitor; â€œpaper and pencilâ€ self-report process recording method. The Warmth Monitor has been used in a large number of empirical studies in marketing since, but the most recent versions of the procedure are computerized. The two methods of administering the Warmth Monitor are compared in this research.
Mixed-Initiative Decision Theoretic Planning for Cooperative Control

Mixed-initiative cooperative control can help overcome the limitations of autonomous robots by introducing a human operator into the control loop. Developing new computational models for cooperative control presents several key questions : how to account for the different perceptual and action abilities of the robot versus the human operator, the different costs of their actions, and the fact that human operators cannot switch their attention and take over control instantly. We present a decision-theoretic approach to solve these problems using Mixed-Initiative Markov Decision Processes (MI-MDPs). This framework allows us to compute optimal plans that not only tell the robot what actions to perform, but also when to request human attention or transfer control to the human operator. The result is a model with a varying degree of autonomy, particularly suitable for robots exploring a domain with regions that are too complex or risky for autonomous operation. Experimental results confirm the effectiveness of this approach in common scenarios in which fully-autonomous operation or continuous human control are both undesirable.
Effects of unsown patches in autumn-sown fields on Skylark territory densities

Intensified cultivation of farmland is widely recognized to act negatively on many organisms, including birds as the Skylark (Alauda arvensis). During the last decades, this species has been showing a population decline of about 50-75 percent in northwestern Europe, including Sweden. One important factor that is considered to be a key driver of this decline is the switch from spring- to autumn-sowing of cereals. This change in farming practice has been shown to reduce food availability for skylarks and other species that rely on crop fields for foraging and nesting. To improve this situation, skylark plots (SPs), i.e. small (16-20 m2) unsown patches within winter cereal crops, have been developed in Great Britain during the last decade. The idea with SPs is to make it easier for skylarks to forage, since the sparser vegetation in SPs makes it easier to find food (i.e. invertebrates). From Great Britain the method has been shown to work well, increasing the breeding success of skylarks. However, the extent by which SPs contribute to improve breeding opportunities in Swedish arable farmland is unknown. There are structural differences in the agricultural landscapes of Sweden and Great Britain, with a higher relative proportion of spring sown cereals in Sweden. This might indicate that SPs have a lower positive effect when applied in Sweden, since the high proportion of spring cereals (sparser vegetation) makes it possible for skylarks to find food anyway. Thus it is important to study if SPs have a positive effect on skylarks in Sweden, before applying the method in a huge scale.
APPLICATION OF SYNTHETIC BANDWIDTH APPROACH IN SAR POLAR FORMAT ALGORITHM USING THE DERAMP TECHNIQUE

The problem of wide bandwidth management in ultra-high resolution SAR systems can be solved by adopting stepped chirps and applying synthetic bandwidth approach. However, high resolution SAR image formation is a non-separable 2-D impulse compression processing, so the synthetic bandwidth procedure should be modified correspondingly with the image formation algorithm adopted. This paper demonstrates the application of synthetic bandwidth approach in SAR Polar Format Algorithm (PFA) using the deramp technique. The problem of motion compensation between the sub-pulses within a burst is discussed, and the signal processing flows are investigated in detail. The presented approach is validated by point target simulation.
Relationship between infill patterns in 3D printing and Hounsfield Unit

Introduction: One of the requirements for a phantom to correctly simulate the human body is that the radiation attenuation of the material used is compatible with the values ​​of its corresponding tissues. The aim of this study is to evaluate the values ​​of Hounsfield Unit (HU) in a 3D printed material in order to verify its compatibility, on tomography, with human tissues, so that it can be used as feedstock for simulators constructed in 3D printers. Methods : Cubes with 2cm of edge were printed using ABS filament with 8 different forms of internal filling. The samples were irradiated by a CT scanner, the measured HUs and their results compared to the literature. Results : Modification of the filling form as well as its percentage influenced the HU values ​​that ranged from -133 to -451. Conclusion : The specific variations of internal fill patterns directly influence the interaction of the material used with the radiation, thus altering the HU values. Despite the variation found, the HU values ​​were sufficient to simulate few tissues in the human body, which requires future studies with new materials that further attenuate the radiation and the range of tissues to be expanded.
ORIGINAL ARTICLE: Phylogeography of the giant wood spider (Nephila pilipes, Araneae) from Asian–Australian regions

Aim There are currently few population genetic studies on widely distributed SE Asian terrestrial organisms. We have studied the genetic diversification pattern of the giant wood spider, Nephila pilipes (Araneae: Tetragnathidae) to see whether fluctuations in rain forest extents generated by Quaternary climatic changes left signatures on populations of this agile terrestrial arthropod.
