ROBO - Autonomous Football Robot (2019)

The autonomous football robot (ROBO) was designed to enhance the knowledge in the field of robotics and computer vision through the robot development. The goal was to learn the use of robotic kits, the Raspberry Pi micro-controller to control the robot motion, the Raspbian operating system (Linux based OS), the python programming language and the computer vision library (OpenCV). The robot design consists of hardware and software designs. For the robot hardware design and implementation, the robotic kit were built, tested, and attached to a 3D custom printing gripper and kicker along with the 180 degrees rotational Raspberry Pi camera by servo motor. Lastly, a small breadboard was attached to set up the pulse, voltage, and the ground for the servo motors. For the robot software design, there are two algorithms or modes in the program, ball mode and goal mode. The ball mode start with ball detection and end with the ball grab. The goal mode start with the goal search and end with kick the ball into the goal. A 150 experiments done for three different configuration of the robot. Each configuration consists of 50 experiments. The results were 2% task error for the first configuration, 10% for the second, and 22% for the third. The task errors were because of the mechanical failure of the kicker. The kicker was unable to reach the ball into the goal from far distance. A future work can be a better kicker with more power.
Esthesioneuroblastoma: a Case Report and Review of the Literature (2012)

We report on a patient who presented to our clinic with a one-year history of diplopia in the left eye, epistaxis for one month and pain in the occipital area of the head. A biopsy of the area was performed and the lesion was diagnosed as Esthesioneuroblastoma also known olfactory neuroblastoma. Due to the size of the tumor and involvement of the vital intracranial structures it was decided to prescribe a palliative care program and palliative radiotherapy.
Computational evaluation of halogen-bonded cocrystals enables prediction of their mechanochemical interconversion reactions (2023)

Periodic density-functional theory (DFT) calculations were used to predict the thermodynamic stability and the likelihood of interconversion between a series of halogen-bonded cocrystals. The outcomes of mechanochemical transformations were in excellent agreement with the theoretical predictions, demonstrating the power of periodic DFT as a method for designing solid-state mechanochemical reactions prior to experimental work. Furthermore, the calculated DFT energies were compared with experimental dissolution calorimetry measurements, marking the first such benchmark for the accuracy of periodic DFT calculations in modelling transformations of halogen-bonded molecular crystals.
Final Report Real Time Monitoring of Rates of Subsurface Microbial Activity Associated with Natural Attenuation and Electron Donor Availability (2016)

The project was successful in developing new sensing technologies for monitoring rates of microbial activity in soils and sediments and also developed a novel proof-of-concept for monitoring the presence of bioavailable concentrations of a diversity of metabolites and toxic components in sedimentary environments. These studies led not only to publications in the peer-reviewed literature, but also two patent applications and a start-up company.
Localization of Interleukin 1 Type I Receptor mRNA in Rat Brain (1994)

During states of infection and inflammation, systemic interleukin 1 (IL-1) results in clear biological effects mediated through the central nervous system, such as fever, anorexia, and activation of the hypothalamic-pituitary-adreno-cortical axis. Given the multiple central effects of IL-1 in the rat, it would be expected that IL-1 receptors ought to be present in rat brain. However, no previous studies have localized IL-1 receptor or its mRNA in rat brain, possibly due to the fact that interspecies probes were used in previous studies. The recent cloning of the rat IL-1 type-I receptor (IL-1RI) has permitted us to conduct an in situ hybridization study using a species-specific, 35S-labeled anti-sense riboprobe to localize IL-1 receptor mRNA in rat brain. We localized IL-1RI mRNA in the hippocampus, choroid plexus, and cerebellum. At the cellular level we found IL-1RI mRNA in low to moderate levels in hippocampal neurons and in Purkinje cells of the cerebellar cortex, and in high levels in the endothelium of postcapillary venules and in glial cells surrounding arterioles throughout the brain. This pattern of localization provides support to the concept that IL-1 crosses the blood-brain barrier. Future studies are needed to clarify how the expression of the gene encoding IL-1RI is regulated in brain tissue.
User-Based Motion Sensing and Fuzzy Logic for Automated Fall Detection in Older Adults (2007)

More than one third of community-dwelling older adults and up to 60% of nursing home residents fall each year, with 10-15% of fallers sustaining a serious injury. Reliable automated fall detection can increase confidence in people with fear of falling, promote active safe living for older adults, and reduce complications from falls. The performance of a 2-stage fall detection algorithm using impact magnitudes and changes in trunk angles derived from user-based motion sensors was evaluated under laboratory conditions. Ten healthy participants were instrumented on the front and side of the trunk with 3D accelerometers. Participants simulated 9 fall conditions and 6 common activities of daily living. Fall conditions were simulated on a protective mattress. The experimental data set comprised 750 events (45 fall events and 30 nonfall events per participant) that were classified by the fall detection algorithm as either a fall or a nonfall using inputs from 3D accelerometers. Significant differences for impacts recorded, trunk angle changes (p<0.01), and detection performances (p<0.05) were found between fall and nonfall conditions. The proposed algorithm detected fall events during simulated fall conditions with a success rate of 93% and a false-positive rate of 29% during nonfall conditions. Despite a slightly superior identification performance for the accelerometer located on the front of the trunk, no significant differences were found between the two motion sensor locations. Automated detection of fall events based on user-based motion sensing and fuzzy logic shows promising results. Additional rules and optimization of the algorithm will be needed to decrease the false-positive rate.
Catalase function in plants: a focus on Arabidopsis mutants as stress-mimic models (2010)

Hydrogen peroxide (H(2)O(2)) is an important signal molecule involved in plant development and environmental responses. Changes in H(2)O(2) availability can result from increased production or decreased metabolism. While plants contain several types of H(2)O(2)-metabolizing proteins, catalases are highly active enzymes that do not require cellular reductants as they primarily catalyse a dismutase reaction. This review provides an update on plant catalase genes, function, and subcellular localization, with a focus on recent information generated from studies on Arabidopsis. Original data are presented on Arabidopsis catalase single and double mutants, and the use of some of these lines as model systems to investigate the outcome of increases in intracellular H(2)O(2) are discussed. Particular attention is paid to interactions with cell thiol-disulphide status; the use of catalase-deficient plants to probe the apparent redundancy of reductive H(2)O(2)-metabolizing pathways; the importance of irradiance and growth daylength in determining the outcomes of catalase deficiency; and the induction of pathogenesis-related responses in catalase-deficient lines. Within the context of strategies aimed at understanding and engineering plant stress responses, the review also considers whether changes in catalase activities in wild-type plants are likely to be a significant part of plant responses to changes in environmental conditions or biotic challenge.
Pectin: A new perspective from the biorefinery standpoint (2015)

Abstract Pectin is a natural product of central importance in the emerging biorefinery that uses fruit waste as a raw material. Generally obtained from lemon peel or from apple pomace, pectin is mainly used as a thickener and a stabilizer in the food industry. Due to its unique chemical properties and biochemical activity, however, its use is growing in many other sectors. Providing a unified view of the main research and utilization trends, this study identifies open opportunities toward larger scale production of a valued biopolymer that, we argue, will shortly emerge as a central product of the biorefinery, and of the citrus‐based biorefinery in particular. © 2015 Society of Chemical Industry and John Wiley &amp; Sons, Ltd
Syntheses, crystal structures, photophysics and cation-binding studies of luminescent functionalized ruthenium polypyridine complexes with orthometallated aminocarbene ligands (2003)

A series of luminescent functionalized ruthenium polypyridine complexes with orthometallated aminocarbene ligands has been synthesized and their photophysical properties studied. The cation-binding properties of one crown-ether functionalized complexes have also been studied. The X-ray crystal structures of [Ru(bpy)2C(CH2–B15C5)NHC6H3Br]OTf and [Ru(5,5′-Me2bpy)2C(CH2Ph)NHC6H3Br]OTf have been determined (bpy = 2,2′-bipyridine; 5,5′-Me2bpy = 5,5′-dimethyl-2,2′-bipyridine; B15C5 = benzo-15-crown-5).
Double-output induction generator operating at subsynchronous and supersynchronous speeds: steady-state performance optimisation and wind-energy recovery (1992)

The paper covers the steady-state analysis of a wound-rotor induction generator operated at varying shaft speeds in the subsynchronous and supersynchronous regions, by control of both the magnitude and direction of slip power. A modified equivalent circuit is used in the analyses in which core losses and harmonics are ignored. The resulting nonlinear algebraic equations are solved numerically. An optimum control strategy, which maximises the total electrical power output of the double output induction generator is determined, and theoretical results are verified experimentally with particular emphasis on the system including naturally commutated convertors. The limitations of naturally commutated convertor circuits and their effects on the output power characteristic of the system are also discussed. This system shows considerable advantage in the field of wind-energy conversion. Its performance is optimised on the basis of annual energy production by calculating optimum values of gear ratio and generator size for the given turbine characteristic and site wind regime. Also, a comparison is made among optimised versions of alternative induction generator schemes used in wind-energy conversion systems, on the bases of annual energy production and transfer characteristic for the same site and turbine.

IL-33 released by alum is responsible for early cytokine production and has adjuvant properties (2015)

Human vaccines have used aluminium-based adjuvants (alum) for >80 years despite incomplete understanding of how alum enhances the immune response. Alum can induce the release of endogenous danger signals via cellular necrosis which elicits inflammation-associated cytokines resulting in humoral immunity. IL-33 is proposed to be one such danger signal that is released from necrotic cells. Therefore, we investigated whether there is a role for IL-33 in the adjuvant activity of alum. We show that alum-induced cellular necrosis results in elevated levels of IL-33 following injection in vivo. Alum and IL-33 induce similar increases in IL-5, KC, MCP-1, MIP-1α and MIP-1β; many of which are dependent on IL-33 as shown in IL-33 knockout mice or by using an IL-33-neutralizing recombinant ST2 receptor. Furthermore, IL-33 itself functions as an adjuvant that, while only inducing a marginal primary response, facilitates a robust secondary response comparable to that observed with alum. However, IL-33 is not absolutely required for alum-induced antibody responses since alum mediates similar humoral responses in IL-33 knockout and wild-type mice. Our results provide novel insights into the mechanism of action behind alum-induced cytokine responses and show that IL-33 is sufficient to provide a robust secondary antibody response independently of alum.
Does Left Atrial Volume and Pulmonary Venous Anatomy Predict the Outcome of Catheter Ablation of Atrial Fibrillation? (2009)

LA volume is an independent predictor of AF recurrence after catheter ablation. Additionally, PV anatomy did not have any effect on the outcome. These findings suggest that an assessment of LA volume may be incorporated into the preprocedural evaluation of patients being considered for AF ablation.
Unknown Blocking Scheme for Low Control Data Volume and High Observability (2007)

This paper presents a new blocking logic to block unknowns for temporal compactors. The proposed blocking logic can reduce data volume required to control the blocking logic and also increase the number of scan cells that are observed by the temporal compactors. Control patterns, which describe values required at the control signals of the blocking logic, are compressed by LFSR reseeding. In this paper, the blocking logic gates for some groups of scan chains that do not capture unknowns are bypassed. Since all the scan cells in these scan chain groups are observed without specifying the corresponding bits in control patterns, fewer specified bits are required and more scan cells are observed. The seed size is further reduced by reducing numbers of specified bits in the densely specified control patterns. The proposed method can always achieve the same fault coverage that can be achieved by direct observation of scan chains. Experiments with large industrial designs clearly demonstrate that the proposed method is scalable to large circuits. Hardware overhead for the proposed blocking logic is very low
Design of an optoelectronic cellular processing system with a reconfigurable holographic interconnect (1994)

The design of an optoelectronic parallel processing system is presented. In this system a reconfigurable computer-generated hologram is used to perform a shift-invariant optical interconnection operation. Scalability issues are investigated, and simple cellular processing operations are experimentally demonstrated.
Peptide ligand-mediated trade-off between plant growth and stress response (2022)

Deciding whether to grow or to divert energy to stress responses is a major physiological trade-off for plants surviving in fluctuating environments. We show that three leucine-rich repeat receptor kinases (LRR-RKs) act as direct ligand-perceiving receptors for PLANT PEPTIDE CONTAINING SULFATED TYROSINE (PSY)-family peptides and mediate switching between two opposing pathways. By contrast to known LRR-RKs, which activate signaling upon ligand binding, PSY receptors (PSYRs) activate the expression of various genes encoding stress response transcription factors upon depletion of the ligands. Loss of PSYRs results in defects in plant tolerance to both biotic and abiotic stresses. This ligand-deprivation-dependent activation system potentially enables plants to exert tuned regulation of stress responses in the tissues proximal to metabolically dysfunctional damaged sites where ligand production is impaired.
Inhibited Light Propagation and Broadband Reflection in Photonic Air-Sphere Crystals (1999)

We have performed optical reflectivity experiments and band structure diffraction calculations on fcc photonic crystals, consisting of air spheres in titania ( $\mathrm{TiO}{}_{2}$). The spectra reveal Bragg peaks whose large widths agree well with the calculations. The peaks overlap in many directions, causing the propagation of light to be limited by Bragg reflection to $45%$ of the $4\ensuremath{\pi}$ solid angle. This illustrates that the air-sphere crystals interact so strongly with light that an unprecedented limitation in the directions of propagation of light in photonic crystals is achieved.
Induction of the SOS response in Escherichia coli by 4-quinolone antimicrobial agents (1987)

The induction of the RecA protein in strains of Escherichia coli was demonstrated for five 4-quinolone compounds. Using a recA::lac fusion, the expression of the recA gene was quantified for each agent. Induction was shown to be time and concentration-dependent. At a certain concentration (dependent on each 4-quinolone) maximum induction was observed. Above this concentration, reduced induction was observed with an increase in 4-quinolone concentration. The inducing concentration of each 4-quinolone correlated well with the antibacterial activity of each agent.
Endogenous PTH Deficiency Impairs Fracture Healing and Impedes the Fracture-Healing Efficacy of Exogenous PTH(1-34) (2011)

Absence of endogenous PTH1-84 impedes bone fracture healing. Exogenous PTH1-34 can act in the absence of endogenous PTH but callus formation, including accelerated endochondral bone formation and callus remodeling as well as mechanical strength of the bone are greater when endogenous PTH is present. Results of this study suggest a complementary role for endogenous PTH1-84 and exogenous PTH1-34 in accelerating fracture healing.
Spatiotemporal processing of gated cardiac SPECT images using deformable mesh modeling (2005)

In this paper we present a spatiotemporal processing approach, based on deformable mesh modeling, for noise reduction in gated cardiac single-photon emission computed tomography images. Because of the partial volume effect (PVE), clinical cardiac-gated perfusion images exhibit a phenomenon known as brightening-the myocardium appears to become brighter as the heart wall thickens. Although brightening is an artifact, it serves as an important diagnostic feature for assessment of wall thickening in clinical practice. Our proposed processing algorithm aims to preserve this important diagnostic feature while reducing the noise level in the images. The proposed algorithm is based on the use of a deformable mesh for modeling the cardiac motion in a gated cardiac sequence, based on which the images are processed by smoothing along space-time trajectories of object points while taking into account the PVE. Our experiments demonstrate that the proposed algorithm can yield significantly more-accurate results than several existing methods.

A 98 W 1178 nm Yb-doped solid-core photonic bandgap fiber oscillator (2013)

A high-power ytterbium-doped solid-core photonic bandgap fiber laser directly oscillating at 1178 nm is reported. The sharp-cut bandpass distributed filtering effect of photonic bandgap fiber can suppress amplified spontaneous emission (ASE) in the conventional high-gain spectral region. The oscillator is composed of a high reflection fiber Bragg grating spliced with a 39 m gain fiber and a Fresnel fiber end surface. A model based on rate equations is investigated numerically. A record output power of 98 W is achieved with a slope efficiency of 54%. The laser linewidth is 0.5 nm. The spectrum at 98 W indicates that ASE and parasitic lasing are suppressed effectively.
Preliminary phytochemical screening, acute toxicity and effect of Albuca amoena extracts on the central nervous system (2021)

Introduction: Albuca amoena is a Moroccan-Algerian endemic medicinal plant with various implications. The aim of this study is to identify phytochemical compounds of the plant, check its acute toxicity, and test its anti-depressive, anxiolytic, and analgesic effects on the central nervous system (CNS). Methods: The estimation of chemical compounds was carried out according to coloring and precipitation reactions. The Organization of Economic Cooperation and Development guidelines 423 and 402 made it possible to verify the acute toxicity of the plant orally and dermally. The sedative activity was performed according to 4 tests: rotarod, hole-board, traction, and chimney tests. The anti-depressive, anxiolytic, and analgesic effects were evaluated by forced swimming, light/dark, and writhing tests, respectively. Results: The phytochemical analysis showed that A. amoena contained a mixture of phytochemical compounds like terpenes, alkaloids, and polyphenols. According to the acute toxicity tests, the lethal dose of 50% (LD50) of A. amoena hydroalcoholic extract was between 300 and 2000 mg/kg orally and higher than 2000 mg/kg dermally. Moreover, the result of the behaviour tests of sedative and analgesic activities revealed that A. amoena hydroalcoholic extract exerted positive effects on the CNS. Conclusion: These results show the anti-depressive, anxiolytic, and analgesic effects of the bioactive substances present in A. amoena on the CNS and provide access to further investigations to highlight the main compounds of this plant and their mechanisms of actions.
Development of printed ITO coatings on PET and PEN foil for flexible organic photodiodes (2008)

ITO (tin doped indium oxide) coatings with a sheet resistance of 2 to 3 k&Omega;(square) were produced by gravure printing process on PET and PEN foil. The printing paste consisted of ITO nanoparticles which were dispersed in a solvent by using a surfactant. The dispersion was mixed with a binder and a photo initiator before printing. The printed films were hardened under UV-irradiation at low temperatures (< 130&deg;C). The sheet resistance could be decreased by heat treatment at 120&deg;C under forming gas atmosphere (N<sub>2</sub>/H<sub>2</sub>) to 1.5 k&Omega;(square). The transmission of the ITO coated PET and PEN foils is more than 80 % in the visible range. The ITO films were directly used as the bottom electrode in an organic photodiode (OPD). The setup of the OPD originates from the well known Tang photodiode, consisting of a stacked layer of copper phthalocyanine (p-type material) and perylene tetracarboxylic bisbenzimidazole (n-type material). The photodiodes are characterised via current-voltage (I-V) characteristics. The performance of the photodiodes with printed ITO on plastic substrates could be improved by the deposition of a PEDOT/PSS layer (Baytron<sup>(R)</sup> P) on the ITO coated foils and was then comparable to the performance of photodiodes with semi-transparent gold as anode on PET substrates. These results demonstrate the suitability of the printed ITO layers as anode for organic photodiodes.
