Packet Format Design and Decision Directed Tracking Methods for Filter Bank Multicarrier Systems (2010)

Packetized data transmission is commonly used in wireless communication systems. Each packet starts with a preamble which is used to synchronize the receiver with carrier frequency of the incoming signal, to find a good timing phase, and to identify the channel impulse response or to adjust a set of channel equalizer parameters. In this paper, following the same philosophy, we develop a packet format for multicarrier systems that operate based on filter banks, filter bank multicarrier (FBMC) systems. The related algorithms for carrier frequency and timing recovery as well as channel identification/equalizer adjustment and methods for carrier and timing tracking loops are proposed. The proposed ideas are evaluated and their satisfactory performance are presented through computer simulations.
The Role Of Innovation For Sustainable Development In Eu Member States (2017)

Sustainable socio-economic development represents the central component of the European Union's â€˜Sustainable Development Strategyâ€™ document. The E.Uâ€™s economic capacity for innovation, competitiveness and eco-efficiency is here analyzed through indicators like: R D, labor productivity, eco-innovation and energy intensity The progress of these indicators, in its turn, is analyzed for individual EU Member States in the aim of a large picture drawn for how exactly the EU has performed in terms of objectives and targets written in the initial Strategy. Ultimately, this below paper bases on the Eurostat data on the 2000-2015 interval.
CLINICAL APPLICATIONS OF LHRH AND ITS ANALOGUES (1983)

The physiological requirement for activation of pituitary gonadotrophin secretion by pulsatile LHRH stimulation is discussed, and compared with the effect of pituitary stimulation by LHRH agonists. Initial stimulation is followed by a phase of progressive pituitary and gonadal inhibition. This inhibition is fully reversible at the end of agonist treatment. Clinical applications of high dose suppression are the treatment of precocious puberty and hormone-dependent tumours (mammary and prostatic carcinoma). In women, agonist administration by nasal spray is a reversible method of inhibiting ovulation, and may also be useful in the treatment of endometriosis. Clinical advantages of agonist therapy are favourable biological tolerance, lack of side effects and rapid reversibility.
Large area multicrystalline silicon buried contact solar cells with bulk passivation and an efficiency of 17.5% (2003)

The purpose of this study was the development of a processing sequence for buried contact solar cells on multicrystalline silicon (mc-Si). The applied process includes mechanical V-texturing for the reduction of reflection losses as well as bulk passivation by a remote hydrogen plasma source. Record high efficiencies of 17.5% (V/sub /spl prop//=628 mV, J/sub sc/=36.3 mA/cm/sup 2/, FF=76.8%, independently confirmed at FhG-ISE) have been obtained on Polix mc-Si on a solar cell area of 144 cm/sup 2/. The high J/sub sc/ results from low shadowing and reflection losses, high bulk diffusion lengths and from a selective emitter structure. Hydrogenation was investigated for Baysix mc-Si and led to an increase in V/sub /spl prop// of 5-11 mV and in J/sub sc/ of 0.3-0.6 mA/cm/sup 2/, which were caused by an increase in the effective diffusion length of 40-50 /spl mu/m. It has been demonstrated, that hydrogenation from a PECVD SiN/sub x/ layer applied to screen printed solar cells could be more effective than remote plasma hydrogenation in BCSCs.

Volcano plots in hydrogen electrocatalysis – uses and abuses (2014)

Sabatier's principle suggests, that for hydrogen evolution a plot of the rate constant versus the hydrogen adsorption energy should result in a volcano, and several such plots have been presented in the literature. A thorough examination of the data shows, that there is no volcano once the oxide-covered metals are left out. We examine the factors that govern the reaction rate in the light of our own theory and conclude, that Sabatier's principle is only one of several factors that determine the rate. With the exception of nickel and cobalt, the reaction rate does not decrease for highly exothermic hydrogen adsorption as predicted, because the reaction passes through more suitable intermediate states. The case of nickel is given special attention; since it is a 3d metal, its orbitals are compact and the overlap with hydrogen is too low to make it a good catalyst.
Fluoxetine suppresses human cataplexy (1994)

We evaluated fluoxetine in six patients with poorly controlled cataplexy by beginning patients on a single 20 mg dose without any change in their current medications. Once benefit occurred, we discontinued or reduced other anticataplectic medication. Reduction in the number of cataplectic episodes per week after 20 weeks of treatment constituted the basis for efficacy determination. Patients experienced a mean reduction of 92% (a mean drop in frequency of 21.7 to 1.7 episodes per week). Although fluoxetine-induced headache occurred in one patient, the other five reported no side effects at the doses used. The results of this pilot study demonstrate that fluoxetine safely and effectively suppresses cataplexy and reduces the need for other, less desirable, anticataplectic agents.
Summation and multiplication: two distinct operation domains of leaky integrate-and-fire neurons (1991)

The spiking frequency of a leaky integrate-and-fire (LIF) neuron can be proportional to the sum or the product of a number n≥2 of input frequencies. In the paper, the parameter domains (discharge time constants and synaptic weights) for these two operation modes are defined theoretically and studied by simulations. Summation is based on the frequency division principle and requires discharge time constant as long as possible. In this mode, the LIF neuron is subject to phase locking effects and is insensitive to the irregularity of the input spike trains. Multiplication is based on coincidence detection and requires shorter time constants. Simulations show that the quality of the mulutiplication function decreases for large irregularities of the input spike trains, that there is an optimum value of the synaptic weights and that there is a consequent input-output frequency level drop. In the brain, the frequency level decrease observed from retina to higher cortical areas might indicate the presence of multiplication-type layers. Physiologically, distant synapses are probably mainly involved in summation while proximal synapses are used for multiplicatton. It is proposed that learning involves synaptic relocation as well as weights modification.

Low R:FR Light Quality Delays Flowering of <i>E7E7</i> Soybean Lines (2001)

A new locus ( E7 ) controlling flowering and maturity time, and photoperiod response in soybean [ Glycine max (L.) Merr.] was identified by means of 20‐h days of low (0.7) red:far‐red (R:FR) light quality. The objective of this study was to characterize light quality and photoperiod responses of E7E7 and e7e7 soybean near‐isogenic lines. E7E7 and e7e7 lines, in two genetic backgrounds, were grown in 20‐h photoperiods with four R:FR light qualities (0.7, 1.2, 2.3, 2.7) and in 12‐h photoperiods with 0.7 and 2.7 R:FR light quality. Under high R:FR, all isolines flowered early and similarly in both 12‐ and 20‐h photoperiods. In 20‐h photoperiods, as R:FR light quality approached that of natural day light (1.2), E7E7 lines flowered 6 to 7 d later than e7e7 lines, while under low R:FR (0.7), E7E7 lines flowered about 15 d later than e7e7 lines. Under low R:FR, all isolines flowered later under 20‐h compared with 12‐h photoperiods. Six ‘Harosoy’ isolines ( e7e7 and 5 E7E7 lines) were grown in 1998 and 1999 in the field under natural daylength and daylength extended to 20 h with incandescent lamps (ILD). The e7e7 line matured 6 d earlier than the E7E7 line under natural and ILD photoperiod. An ILD treatment was simulated in growth cabinets with 4+12+4 h of incandescent light and was compared with 12‐, 20‐, and 24‐h photoperiods. All lines flowered early and similarly under 12‐h photoperiod. The 4+12+4‐h treatment delayed flowering less than the 20‐h photoperiod. Flowering was not delayed further when the photoperiod was extended from 20 to 24 h. The E7E7 lines were sensitive to light quality. They did not perceive long days of high R:FR light quality, but under natural daylight and under low R:FR light quality, E7 delayed flowering.
Short-duration therapy with terbinafine 1% cream in dermatophyte skin infections (1994)

In a multicentre, double-blind, parallel-group study, the efficacy and safety of a single application of terbinafine 1% cream was compared with 3, 5 and 7 days' once-daily therapy in the treatment of tinea pedis and tinea corporis/cruris. Seventy-eight patients with tinea pedis (58 male, 20 female; mean age 36, range 19-80) and 21 patients with tinea corporis or tinea cruris (16 male, 5 female; mean age 37, range 22-72), presenting in general practice, were entered into the study. Of these, 65 patients with tinea pedis and 14 with tinea corporis or cruris completed the study and were evaluable. Twenty-eight days after commencing therapy 78, 83, 82 and 83% of patients with tinea pedis in the 1-, 3-, 5-, and 7-day treatment groups, respectively, were mycologically cured, and 61, 78, 71 and 67%, respectively, were 'effectively treated'. There was no statistically significant difference between treatment groups. Similarly high cure rates were seen in patients with tinea corporis and tinea cruris. Three months after commencing therapy there was little evidence of relapse. The study shows that there is a significant potential for short-duration therapy with terbinafine 1% cream in tinea infections of the skin, emphasized here by the high cure rates obtained following a single application.
Built-in self-test generator design using nonuniform cellular automata model (1998)

The paper presents a new test vector generator construction technique for built-in self-test (BIST). The technique is based on the cellular automata model nonuniform cellular automata (NUCA). In NUCA, cell neighbourhoods are not predefined but decided for each cell dynamically by the test vector set. The problem of finding the minimum NUCA topology that can generate a given precomputed test vector sequence is worked on and reduced to independent set-covering problems. Also, a polynomial time algorithm that decides on a small, but not minimal, cellular topology is introduced. Simulations using benchmark circuits showed that the hardware component cost of a test vector generator based on the NUCA model is considerably less than the cost of a single programmable logic array (PLA) approach.
3-D imaging of complex source fields with a Compton Camera Imager (1997)

Many practical applications of Compton Camera Imager (CCI) systems require imaging of extended sources in diffuse backgrounds. This paper presents image reconstructions of simulated CCI system data from extended source distributions with and without a diffuse background. The simulations were performed using a biased photon transport Monte Carlo code which was validated with MCNP results. The reconstruction code used an iterative back-projection technique based upon the expectation maximization maximum likelihood method. Examples are shown of two clearly resolved cylindrical sources, an extended source both with and without background, and extended sources at multiple depths within the volume. The results demonstrate the ability to image extended sources in high backgrounds with a limited number of events.

Position/force control of an arm/gripper system for space manipulation (2002)

In advanced robotics applications, as those foreseen in space, some degree of dexterity and autonomy is necessary in order execute tasks in unstructured environments. For this purpose besides the kinematic configuration of the device other basic issues are the sensorial equipment and proper control strategies. The paper presents an experimental activity for the validation of a robotic gripper for space applications. In particular the project foresees the compatibility of the gripper with the EUROPA arm, developed by ASI and Tecnospazio. The key points of the gripper design are the wide working space compared with its physical dimensions and the capability to deal with free-flying objects in zero-gravity conditions. This capability is achieved by using proximity and force/torque sensors and by properly controlling and coordinating the gripper and the carrying arm. After a brief illustration of the main features of the gripper, the experimental activity is presented and the results achieved so far are discussed.
Visualizing Memory Utilization for the Purpose of Vulnerability Analysis (2008)

The expansion of the internet over recent years has resulted in an increase in digital attacks on computers. Most attacks, including the more dangerous ones, directly target program vulnerabilities. The increase in attacks has prompted a need to develop new ways to classify, detect, and avoid vulnerabilities. The effectiveness of these goals relies on the development of new methods and tools that facilitate the process of detecting vulnerabilities and exploits. This thesis presents the development of a tool that provides a visual representation of main memory for the purpose of security analysis. The tool provides new insight into memory utilization by software; users are able to see memory utilization as execution time progression, visually distinguish between memory behaviors (allocations, writes, etc), and visually observe special relationships between memory locations. The insight enables users to search for visual evidence that software is vulnerable, violated, or utilizing memory incorrectly. The development process for our visual tool has three stages: (1) identifying the memory utilization policies of the Windows 32-bit operating system; (2) identifying the data required for visual representations of memory and then implementing one possible method to capture the data; and (3) enumerating and implementing requirements for a memory tool that generates visual representations of memory for the purpose of vulnerability and exploit analysis.
Dopamine Transporter Ligands: Recent Developments and Therapeutic Potential (2006)

The dopamine transporter (DAT) is a target for the development of pharmacotherapies for a number of central disorders including Parkinson's disease, Alzheimer's disease, schizophrenia, Tourette's syndrome, Lesch-Nyhan disease, attention deficit hyperactivity disorder (ADHD), obesity, depression, and stimulant abuse as well as normal aging. Considerable effort continues to be devoted to the development of new ligands for the DAT. In this review, we present some of the more interesting ligands developed during the last few years from the 3-phenytropane, 1,4-dialkylpiperazine, phenylpiperidine, and benztropine classes of DAT uptake inhibitors as well as a few less studied miscellaneous DAT uptake inhibitors. Studies related to the therapeutic potential of some of the more studied compounds are presented. A few of the compounds have been studied as pharmacotherapies for Parkinson's disease, ADHD, and obesity. However, most of the drug discovery studies have been directed toward pharmacotherapies for stimulant abuse (mainly cocaine). A number of the compounds showed decreased cocaine maintained responding in rhesus monkeys trained to self-administer cocaine. One compound, GBR 12,909, was evaluated in a Phase 1 clinical trial.
A novel sparse auto-encoder for deep unsupervised learning (2013)

This paper proposes a novel sparse variant of auto-encoders as a building block to pre-train deep neural networks. Compared with sparse auto-encoders through KL-divergence, our method requires fewer hyper-parameters and the sparsity level of the hidden units can be learnt automatically. We have compared our method with several other unsupervised leaning algorithms on the benchmark databases. The satisfactory classification accuracy (97.92% on MNIST and 87.29% on NORB) can be achieved by a 2-hidden-layer neural network pre-trained using our algorithm, and the whole training procedure (including pre-training and fine-tuning) takes far less time than the state-of-art results.

REACTIONS OF ALUMINUM ALKOXIDES WITH ACETYLACETONE, BENZOYLACETONE, AND ETHYL ACETOACETATE (1961)

The observed stability of stable bridge structure, [Formula: see text] in aluminum alkoxides has been explained on the powerful tendency of aluminum to attain co-ordination number 4. This would predict the monomeric nature of the derivatives of the type, (OR) 2 Al(lig), where ligand (lig) is a diketone like acetylacetone (acac), benzoylacetone (bzac), or ketoester like ethyl acetoacetate (etac). This has been confirmed by actual synthesis of these compounds by reactions between aluminum alkoxides (ethoxide and isopropoxide) and acetylacetone, benzoylacetone, and ethyl acetoacetate in equimolecular ratios. These and also (OR)Al(lig) 2 as well as Al(lig) 3 have been shown to be monomeric in boiling benzene. The volatility of the derivatives was found in the order [(OPr i ) 3 Al] 2 > (OPr i ) 2 Al(acac) > (OPr i )Al(acac) 2 . This leads to the conclusion that chelation lowers the volatility and the direct relationship between volatility and molecular complexity, observed in the case of simple alkoxides, is not applicable in these derivatives. Further mixed derivatives of the type Al(acac)(etac) 2 and Al(etac)(acac) 2 have also been synthesized during the course of the above work.
Role of Intraventricular Dispersion of Early Diastolic Filling in Indicating Left Ventricular Diastolic Dysfunction: Assessment by Color M-Mode Inflow Propagation Velocity (2001)

The intraventricular to mitral E velocity ratio (IvE/MvE) and the color M-mode Doppler inflow propagation velocity (LVIPV) were evaluated in 36 healthy controls and 33 patients with hypertension and/or ischemic heart disease. The intraventricular E velocity was significantly lower than the mitral E velocity in the control group (52 vs. 68 cm/s, p < 0.001), but they are similar in the disease group (59 vs. 63 cm/s, p = nonsignificant). Compared with the control group, the disease group had a higher IvE/MvE (0.95 +/- 0.28 vs. 0.78 +/- 0.23, p < 0.01). Nevertheless, the LVIPV was not significantly different between the disease and control groups (53 +/- 14 vs. 56 +/- 13 cm/s, p = nonsignificant). The LVIPV did not correlate with the IvE/MvE (r = 0.202, p = nonsignificant). Therefore, an intraventricular dispersion of early diastolic filling does not seem to indicate impaired left ventricular relaxation.
<i>Lactobacillus rhamnosus</i>and its cell-free culture supernatant differentially modulate inflammatory biomarkers in<i>Escherichia coli</i>-challenged human dendritic cells (2014)

The intestinal immune system maintains a delicate balance between immunogenicity against invading pathogens and tolerance to the commensal microbiota and food antigens. Different strains of probiotics possess the ability to finely regulate the activation of dendritic cells (DC), polarising the subsequent activity of T-cells. Nevertheless, information about their underlying mechanisms of action is scarce. In the present study, we investigated the immunomodulatory effects of a potentially probiotic strain, Lactobacillus rhamnosus CNCM I-4036, and its cell-free culture supernatant (CFS) on human DC challenged with Escherichia coli. The results showed that the levels of pro-inflammatory cytokines such as IL-1β, IL-6, IL-8 and IL-12p70 were higher in the cells treated with live L. rhamnosus than in the cells treated with the CFS. In the presence of E. coli, the supernatant was more effective than the probiotic bacteria in reducing the secretion of pro-inflammatory cytokines. In addition, live L. rhamnosus potently induced the production of transforming growth factor (TGF)-β1 and TGF-β2, whereas the CFS increased the secretion of TGF-β1. However, in the presence of E. coli, both treatments restored the levels of TGF-β. The probiotic strain L. rhamnosus CNCM I-4036 and its CFS were able to activate the Toll-like receptor signalling pathway, enhancing innate immunity. The two treatments induced gene transcription of TLR-9. Live L. rhamnosus activated the expression of TLR-2 and TLR-4 genes, whereas the CFS increased the expression of TLR-1 and TLR-5 genes. In response to the stimulation with probiotic/CFS and E. coli, the expression of each gene tested was notably increased, with the exception of TNF-α and NFKBIA. In conclusion, the CFS exhibited an extraordinary ability to suppress the production of pro-inflammatory cytokines by DC, and may be used as an effective and safer alternative to live bacteria.
