Jointly optimized transmit beamforming and temporal user scheduling in multiuser multicell scenarios based on correlation knowledge (2010)

This paper presents a new approach for a joint optimization of beamforming and temporal user scheduling for intercell interference mitigation in a multiuser multicell scenario using statistical channel knowledge. In general, the resource allocation problem considers two optimization criterions: fairness among the users in the network and a maximized sum rate of all users. The first one is achieved by a network-wide conventional multiuser transmit beamforming and the second one is achieved by an optimal assignment of users to scheduling slots. The resulting optimization problem is proven to be NP-hard, because of its equivalence to the well-known multidimensional assignment problem. A new low complexity algorithm is proposed to find good solutions with respect to the problem complexity. Regarding the performance and complexity, the new algorithm outperforms the simulated annealing technique, which is a well-known technique to overcome local optima.
On the quasi-analytic treatment of hysteretic nonlinear response in elastic wave propagation (1997)

Microscopic features and their hysteretic behavior can be used to predict the macroscopic response of materials in dynamic experiments. Preisach modeling of hysteresis provides a refined procedure to obtain the stress–strain relation under arbitrary conditions, depending on the pressure history of the material. For hysteretic materials, the modulus is discontinuous at each stress–strain reversal which leads to difficulties in obtaining an analytic solution to the wave equation. Numerical implementation of the integral Preisach formulation is complicated as well. Under certain conditions an analytic expression of the modulus can be deduced from the Preisach model and an elementary description of elastic wave propagation in the presence of hysteresis can be obtained. This approach results in a second-order partial differential equation with discontinuous coefficients. Classical nonlinear representations used in acoustics can be found as limiting cases. The differential equation is solved in the frequency domain by application of Green’s function theory and perturbation methods. Limitations of this quasi-analytic approach are discussed in detail. Model examples are provided illustrating the influence of hysteresis on wave propagation and are compared to simulations derived from classical nonlinear theory. Special attention is given to the role of hysteresis in nonlinear attenuation. In addition guidance is provided for inverting a set of experimental data that fall within the validity region of this theory. This work will lead to a new type of NDT characterization of materials using their nonlinear response.
A COMPARATIVE STUDY FOR RHODOPSIN PROTEIN FOLDING PROBLEM (2014)

Proteins are very important components in any living cells. A number of diseases such as Retinitis pigmentosa, Stargadt-like macular degeneration and Doyne Honeycomb Retinal Dystrophy (DHRD) diseases are shown to result from misfunctioning of proteins. Protein folding problem is a way to predict the best and optimal 3D molecular structure (tertiary structure) of a protein which is then considered to be a sign for the protein's proper functionality. This comparative study's purpose is to calculate the protein's energy using the Empirical Conformational Energy Program for Peptides (ECEPP) package and experiments were performed on the Rhodopsin proteinusing three different evolutionary algorithms in order to find the best energy in parallel with the best structure for the protein and a comparison for the results obtained from the three algorithms was performed. It was found that the best result was -11.8 obtained from the Extended Compact Genetic Algorithm (ECGA). ECGA has proved from the obtained results to be the best algorithm from the chosen algorithms in the comparative study in obtaining the Rhodpsin protein's energy and its equivalent structure.
Implication of gut microbiota metabolites in cardiovascular and metabolic diseases (2018)

Evidence from the literature keeps highlighting the impact of mutualistic bacterial communities of the gut microbiota on human health. The gut microbita is a complex ecosystem of symbiotic bacteria which contributes to mammalian host biology by processing, otherwise, indigestible nutrients, supplying essential metabolites, and contributing to modulate its immune system. Advances in sequencing technologies have enabled structural analysis of the human gut microbiota and allowed detection of changes in gut bacterial composition in several common diseases, including cardiometabolic disorders. Biological signals sent by the gut microbiota to the host, including microbial metabolites and pro-inflammatory molecules, mediate microbiome-host genome cross-talk. This rapidly expanding line of research can identify disease-causing and disease-predictive microbial metabolite biomarkers, which can be translated into novel biodiagnostic tests, dietary supplements, and nutritional interventions for personalized therapeutic developments in common diseases. Here, we review results from the most significant studies dealing with the association of products from the gut microbial metabolism with cardiometabolic disorders. We underline the importance of these postbiotic biomarkers in the diagnosis and treatment of human disorders.

A considerable proportion of patients with cerebral palsy due to perinatal asphyxia have spasticity and extrapyramidal signs. Physical therapy and many drugs are being used to relieve symptoms but usually have no noticeable effect. A 44-year-old woman with congenital cerebral palsy who used a wheelchair because of marked spasticity of the legs and choreoathetosis of the face, trunk, and upper extremities had been given haloperidol, tiapride, clonazepam, biperiden, trihexyphenidyl, diazepam, tizanidine, and baclofen. These drugs had minor efficacy that did not outweigh the side effects. ...References1. Elia J. Drug treatment for hyperactive children. Therapeutic guidelines. Drugs. 1993;46:863-71.

A distributed control for interconnected systems (2012)

In this paper we investigate a multi-agent approach for interconnecting systems using the problem of Load Frequency Control. The connections between subsystems are treated by each controller agent as a set of disturbance signals, each area maintaining the tie-lines power flow to specified values; in simulation the communication between neighboring agents was realized in JADE framework and optimization based on the Model Predictive Control concept in Matlab.
Effects of cavitation in the high intensity therapeutic ultrasound (2002)

Tissue destruction with high intensity ultrasound can be explained by the action of two effects: the first is a hyperthermic effect; the second involves physical damage to the cell from cavitation. In the study described, effects of cavitation were investigated as a function of intensity using either shock waves with large negative pulse or a 1-MHz focused field. In the first set of experiments the cavitation was strong enough to achieve focused and deep tissue destruction in the rabbit's liver. In the second set of experiments, it was shown that when cavitation was moderate no significant effect on tumor growth was achieved. It was thought that in these last experiments, the bubbles that appeared in the field strongly reduced the desired thermal effects of the radiation. It appears, then, that there is a set of optimal parameters that allows the best in vivo tumor treatment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Process Mining Tools: A Comparative Analysis (2011)

Process mining is an emerging topic that has attracted the attention of both researchers and vendors. As a result, several process mining solutions have become available on the market. Even though the development of the process mining field and the number of systems available is a positive thing, problems also arise. The most significant one is, perhaps, the lack of standardization and the fact that these tools use their own standards and naming. This can become rather confusing for a process mining user when deciding what is the most suitable system for a task at hand. In this thesis, we propose an evaluation framework that is used to assess the strengths and the weak-nesses of process mining tools. We apply the framework in practice for evaluating four process mining systems: ARIS PPM, Flow, Futura Reflect, and ProcessAnalyzer. The framework is based on a collection of use cases. A use case consists of a typical application of process mining functionality in a practical situation. The set of use cases was collected based on the functionality available in ProM and was vali-dated by conducting a series of ten semi-structured interviews with process mining users and by handing out a survey. The validated collection of use cases formed the base of our tool evaluation. For the actual evaluation, we created for each use case four dimensions: a brief description, a practical
Hyaluronic Acid and Periodontitis (2007)

Hyaluronic acid (HA; synonyms--Hyaluronan, Hyaluronate) is a glycosaminoglycan found in the connective tissue of vertebrates. It is the most abundant glycosaminoglycan of higher molecular weight in the extracellular matrix of soft periodontal tissues. The use of HA in the treatment of inflammatory process is established in medical areas such as orthopedics, dermatology and ophthalmology. In the field of dentistry, it has shown anti-inflammatory and anti-bacterial effects in gingivitis and periodontitis therapy. Due to its tissue healing properties, it could be used as an adjunct to mechanical therapy in the treatment of periodontitis.
Development of a Canopy Volume Reduction Technique for Easy Assessment and Harvesting of Valencia Citrus Fruits (2006)

The design and evaluation of a basic end-effector prototype for automated citrus harvesting was studied. The concept can be easily incorporated into the design of an automated or a robotic citrus harvester. The concept is based on a unique canopy volume reduction approach that takes advantage of the significant flexibility associated with citrus trees. The method provides a temporary reduction in the tree canopy volume, creating space for the action of simple and potentially fast three-axis Cartesian manipulators. The action of the device also creates fruit alignment that can simplify fruit quality assessment and picking. The prototype included a remotely controlled electro-pneumatic powered clipper to cut fruit stems, two remotely controlled pneumatic cylinders, and two hydraulic powered forks to reduce the canopy volume and to guide the cutting device to a specific location inside the tree canopy. The prototype performance was assessed by the quantification of its fruit removal success rate and damage to fruit and tree canopy. The fruit location of three Valencia orange trees was entirely mapped, and the device was operated on a forklift to evaluate its performance. Field trials were conducted in citrus groves located in Davis and Dinuba, California. This simple prototype end-effector successfully harvested an average of 84% of the fruit and caused no significant damage to harvested fruits during the harvest operations. The simple prototype end-effector, developed based on the canopy volume reduction technique, showed potential to reach significant citrus fruit removal. Based on these results, a future redesign of the system may improve the canopy penetration, increase successful removal rates, and maintain negligible fruit damage.
Social Structure in a Commercial City: Saint-John, 1871 (1974)

The manuscript of the Dominion Census of 1871 remains a largely ignored source in Canadian historiography. Perhaps because Canadian historians have been slow to adapt quantitative methodology to the analysis of social and urban phenomena, our historiography has yet to show the influence of documents like the census and the assessment rolls which have been so much in evidence in recent work in the United States and in western Europe. The study described here represents an attempt to explore the usefulness of the census in examining historical societies.
Solvothermal Synthesis and Photoreactivity of Anatase TiO<sub>2</sub> Nanosheets with Dominant {001} Facets (2009)

Owing to wide-ranging industrial applications and fundamental importance, tailored synthesis of well-faceted single crystals of anatase TiO(2) with high percentage of reactive facets has attracted much research interest. In this work, high-quality anatase TiO(2) single-crystal nanosheets mainly dominated by {001} facets have been prepared by using a water-2-propanol solvothermal synthetic route. The synergistic functions of 2-propanol and HF on the growth of anatase TiO(2) single-crystal nanosheets were studied by first-principle theoretical calculations, revealing that the addition of 2-propanol can strengthen the stabilization effect associated with fluorine adsorption over (001) surface and thus stimulate its preferred growth. By measuring the (*)OH species with terephthalic acid scavenger, the as-prepared anatase TiO(2) single-crystal nanosheets having 64% {001} facets show superior photoreactivity (more than 5 times), compared to P25 as a benchmarking material.
The partitioning of petrophysical data: a review (1997)

Abstract Petrophysical analyses are undertaken within a framework of ordered geological systems. The recognition of the natural geological ordering through the grouping and partitioning of petrophysical data is known to be a fundamental requirement of successful petrophysical interpretations. The mathematical basis and examples of the use of a variety of techniques of value in partitioning data are reviewed. Beginning with the simple use of curve discrimination on conventional crossplots, the discussion proceeds by covering increasingly complex but relatively well-known methods including discriminant function analysis, cluster analysis and principal component analysis, and goes on to include multi-dimensional scaling, ‘pigeon-holing’, fuzzy clustering, characteristic analysis, projection pursuit and neural networks. The discussion highlights some of the benefits, and some of the pitfalls, of each technique through the included examples. The discussion encourages the use of exploratory data analysis techniques in the processing and interpretation of petrophysical data and provides a reference framework from which can follow further evaluation of the value of the techniques in circumstances particular to the interested reader

Laser Induced Marking of Polymer Chains with Radical Spin Traps (2008)

Abstract A pathway for marking of polymer chains with radical spin traps during pulsed laser polymerization in free radical polymerization is presented. By introducing a so‐called marker that forms a non‐propagating radical at (or shortly after) the incidence of a laser pulse, a polymer subdistribution is generated by specifically terminating propagating radicals via combination with such a marker radical. The generated polymer subdistribution can subsequently be imaged by modern soft‐ionization mass spectrometry. Herein, the general methodology of the method in which such marker is generated via reaction of an initiating radical with a nitrone is demonstrated on the examples of BA and VAc. magnified image
Synthesis of Functionalized Oxazolones by a Sequence of Cu(II)- and Au(I)-Catalyzed Transformations (2008)

A study concerning a two-step sequence leading to the formation of diversely 1,5-disubstituted oxazolones is described. The mild conditions employed allow the efficient and rapid synthesis of a variety of such compounds via an initial Cu(II)-catalyzed coupling of a bromoalkyne with a secondary tert-butyloxycarbamate followed by a Au(I)-catalyzed cycloisomerization of the N-alkynyl tert-butyloxycarbamates thus obtained.
Synthesising radiance maps from legacy outdoor photographs for real-time IBL on HMDs (2015)

This paper presents a novel method to synthesise a high dynamic range (HDR) spherical radiance map (RM) from a single low dynamic range (LDR) legacy photograph of an outdoor scene. The synthesised HDR RM is then used for real-time image based lighting (IBL) to render 3D virtual objects with plausible illumination matching with the background outdoor scene. Seam Carving (SC) is utilised to extend the legacy photograph to a panoramic image having a wider field of view for both backdrop and RM. Since SC is a content-aware image resizing technique, it effectively preserves important details such as shape and location of the sun in the outdoor scene and minimises distortion while expanding. The boundary of the 360-degree panoramic image used as RM is refined to minimise the seam. The extended LDR RM is then converted into a HDR RM using our novel inverse tone mapping (ITM) that provides fine tuning to simulate sunlight fall-off for sunny outdoor scenes. The synthesised HDR RM provides believable real-world lighting for IBL. With the combination of extended backdrop and real-time IBL, our pipeline can provide a potential solution for augmented reality (AR) rendering via head mounted displays (HMDs), only from a single legacy photograph.
Nanochannel Fabrication and characterization using bond micromachining (2006)

This thesis deals with the fabrication and characterization of nanochannels (channels with at least one dimension in the sub-100 nm range). These channels are important for various areas of research, including DNA analysis systems and chemical sensors. In addition, the behavior of liquids in nano-confinement is of interest for many of the applications. The technologies currently used to fabricate nanochannels are often expensive and/or time consuming or simply not accurate enough. This creates a need for controlled, yet simple fabrication technologies.
A Game Theory based Contention Window Adjustment for IEEE 802.11 under Heavy Load (2022)

The 802.11 families are considered as the most applicable set of standards for Wireless Local Area Networks (WLANs) where nodes make access to the wireless media using random access techniques. In such networks, each node adjusts its contention window to the minimum size irrespective of the number of competing nodes, so in saturated mode and excessive number of nodes available, the network performance is reduced due to severe collision probability. A cooperative game is being proposed to adjust the users’ contention windows in improving the network throughput, delay and packet drop ratio under heavy traffic load circumstances. The system’s performance evaluated by simulations indicate some superiorities of the proposed method over 802.11-DCF (Distribute Coordinate Function).
Understanding cardiac output (2008)

Cardiac output is the amount of blood the heart pumps in 1 minute, and it is dependent on the heart rate, contractility, preload, and afterload. Understanding of the applicability and practical relevance of each of these four components is important when interpreting cardiac output values. In the present article, we use a simple analogy comparing cardiac output with the speed of a bicycle to help appreciate better the effects of various disease processes and interventions on cardiac output and its four components.
EVALUATION OF COST EFFECTIVE ORGANIC FERTILIZERS (2010)

Organic farming/products are becoming very necessary in today’s world to control ecosystem health and to impart related human health benefits, world over there is growing demand for organic produce. A field experiment was conducted at the research farm of Kilpest India Ltd., Bhopal, during 2009 on rice using BGA Chlorella pyrenoidosa and Nostoc muscorum and biological hydrolysate of Soybean .These treatments were compared with recommended dose of Fytozyme. Currently, fytozyme (40% chemically hydrolysed protein solution) is being used as organic fertilizer world over which was taken as positive control. Cost of all the organic amendments were considered and kept at par with the Fytozyme. Results revealed a significant increase in growth parameters and straw yield in plot treated with Chlorella pyrenoidosa. Grain yield was also higher in C. pyrenoidosa (3.35 t/ha) followed by Fytozyme (3.05 t/ha) and Nostoc as well as biological Soy hydrolysate (both 2.81 t/ha). Thus concluding a better viable organic product.\n\n
