Demo (2015)

In this demo, we present interoperability between Bluetooth Low Energy (BLE) and IPv6 routing protocol for low power and lossy networks (RPL). To make the operation of RPL over BLE feasible, we design an adaptation layer between BLE and RPL, termed ALBER. Specifically, we develop three technical features in ALBER which enable BLE to be combined with RPL. First, it broadcasts RPL control messages through BLE using advertising channels with low energy consumption. Second, it updates RPL routing table considering connection management of BLE. Lastly, it estimates link quality based on round trip time of link layer ping packets to provide routing metric for RPL. We implement our ALBER on Linux kernel. This demo will present an operation example of RPL over BLE using ALBER in a small scale multi-hop topology, where each node comprises a Raspberry Pi platform and a BLE dongle.
Familial hereditary thrombocytopenia and HLA (1984)

Three generations of a Jewish family with hereditary thrombocytopenia (HT) are described. The disease was manifested clinically by mild bleeding tendency since infancy. Circumcision, however, did not result in excessive bleeding. HLA study in this family indicated that the HT locus is not linked to HLA.
[Usefulness of magnetic resonance imaging for the diagnosis of acute myocarditis. A case of acute myocarditis as myocardial infarction-like]. (2004)

According to the Dallas criteria, myocarditis is defined histologically as an inflammatory process involving the myocardium with an inflammatory infiltrate and myocyte necrosis or damage. Clinically, myocarditis is an insidious disease that is usually asymptomatic and commonly underdiagnosed. Infact, the symptoms are often non-specific and the majority of cases recover fully with no sequelae. At present, endomyocardial biopsy remains the gold standard for the diagnosis of myocarditis, despite its limited sensitivity and specificity. However, the lack of an association between biopsy evidence of myocarditis and the presence of autoantibodies in patients with clinical signs of myocarditis, the paucity of the positive biopsy findings in large cohorts of patients with suspected myocarditis, the potential discordance between clinical and histologic features and the inherent limitation of histologic diagnosis, suggest that the diagnosis shouldn't be based on histologic examination alone. The magnetic resonance imaging (MRI) with gadolinium can be useful to visualize the localization, activity and extent of inflammation and may be a powerful noninvasive diagnostic tool in acute myocarditis. Infact, MRI achieves a 100% sensitivity and a 90% specificity. We report the case of a 31-year-old male patient with an acute myocarditis with electrocardiographic manifestations like to acute myocardial infarction, whose diagnosis was based on the clinical signs and on the characteristic pattern of the MRI with paramagnetic contrast. The MRI with gadolinium is suggested as noninvasive study to support the diagnosis of acute myocarditis in the correct clinical setting.
Prognostic significance of treatment‐induced pathologic necrosis in extremity and truncal soft tissue sarcoma after neoadjuvant chemoradiotherapy (2014)

In a homogeneous population of patients with high-grade extremity and truncal STS who were treated with neoadjuvant chemoradiotherapy, the extent of pathologic tumor necrosis did not correlate with outcome.
Model‐based control of batch chromatography (2001)

Abstract In the chemical industry, life science products are considered the most promising markets for the near future. Since pharmaceutical products, food, and fine chemicals are subject to increasingly more complex standards and stricter legal restrictions, efficient methods for the separation of thermally unstable products are needed. Chromatographic separations, for example, usually create the main costs of the overall production process. To realize the full potential of the chromatographic separation, the desired product quality has to be maintained, while operating the process at the economic optimum by reliable and efficient process monitoring and control. For control of batch chromatography, model parameters were estimated and operating parameters were optimized online. The concept has been tested on a laboratory‐scale column with an industrial process control system. Experimental results for a sugar separation are given.
A Simple Attack on a Recently Introduced Hash-Based Strong-Password Authentication Scheme (2005)

The user authentication is an important part of network security. Several strong-password authentication protocols have been introduced, but a secure scheme, which probably withstands to several known attacks, is not yet available. Recently, a hash-based strong-password authentication scheme was described in [2], which withstands to the several attacks, including replay, passwordflle compromise, denial-of-service, and insider attacks. However, we show that this protocol is still vulnerable to stolen-verifler, denial-of-service, replay, and impersonation attacks.
Broadband visible reflective metasurfaces for the visualisation of 3D effects (Conference Presentation) (2019)

Dielectric and plasmonic metasurfaces provide excellent control over the shaping of optical wavefronts via the manipulation of polarisation, phase and amplitude of the light. Taking advantage of their subwavelength thicknesses, metasurfaces have shown to be a very promising technology in a variety of applications including beam steering and focusing, polarisation and angular momentum control, enhancement of nonlinear effects, as well as holographic information encoding for 3D displays. Recently, the emergence of virtual reality and augmented reality technologies have led to the constant demand of effective techniques for the 2D visualisation of 3D objects. Normal mapping, for example, is widely used in computer graphics to create shading effects and recreate 3D-like features of surface textures, such as regular patterns, bumps or ripples. Here, we report on the development of the concept of surface normal mapping for the representation of 3D objects and shading effects with optical metasurfaces. In this work, the metasurface is designed to implement diffuse reflection and uses the concept of normal mapping to control its scattering properties. As a proof of principle, a flat diffuse metasurface imitating lighting and shading effects of a 3D cube was fabricated and characterised under incoherent illumination. The “3D image” is displayed directly on the illuminated metasurface and its shading varies in response to the change in illumination angle. The metasurface performs in a broad range of the visible spectrum, including the three main RGB wavelengths. The 3D images created via normal mapping based on optical metasurfaces provide an effective technology for 3D security features and anti-counterfeiting. This type of metasurfaces can also be useful in the design of efficient optical diffusers for display technology and etalons for metrology.
The square-pyramidal PdIIcomplex of a cross-bridged tetraazamacrocycle (1999)

The preparation and crystal structure of chloro(4,11-dimethyl-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane-κ 4 N)-palladium(II) chloride dihydrate, [PdCl(C 14 H 30 N 4 )]Cl.2H 2 O, are described. The Pd II ion is coordinated to all four N atoms of the folded macrobicycle and to a single chloride ligand in a square-pyramidal geometry. The bond to the axial N atom is considerably longer than the others [Pd-N ax 2.461(3) and average Pd-N eq 2.097 (10) A]. The Pd-Cl distance is 2.3407 (10) A.
Nondirect transitions in variable-temperature angle-resolved photoemission from metals (1987)

Temperature-dependent angle-resolved photoemission spectra have been obtained from Cu(001) for normal-emission conditions corresponding to direct transitions originating from various points along the \ensuremath{\Gamma}--\ensuremath{\Delta}--X line. Photon energies were varied from 40 to 106 eV, and specimen temperatures were chosen between 77 and 977 K. Strong temperature dependence was observed at all photon energies, and this has been interpreted in terms of nondirect transitions localized about the expected direct transitions. Such phonon-assisted nondirect transitions are found to contribute significantly, even at low temperature. These nondirect transitions are also found to be semiquantitatively described by a simple modification of the direct-transition model incorporating cylindrical wave-vector broadening centered on the direct transition. Comparing experiment and theory permits estimating the degree of Brillouin-zone averaging involved at a given temperature. This modification of the direct-transition model is based on a more accurate theoretical treatment of such non-direct-transition effects. The consequences of such localized zone averaging due to nondirect transitions on earlier temperature-dependent data for Cu(110) and on studies of ferromagnetic metals near ${T}_{c}$ are also discussed.

The impact of PrsA over-expression on the Bacillus subtilis transcriptome during fed-batch fermentation of alpha-amylase production (2022)

Abstract The production of the alpha-amylase (AMY) enzyme in Bacillus subtilis at a high rate leads to the accumulation of unfolded AMY, which causes secretion stress. The over-expression of the PrsA chaperone aids the enzyme folding and reduces stress. To identify affected pathways and potential mechanisms involved in the reduced growth, we analyzed the transcriptomic differences during fed-batch fermentation between a PrsA over-expressing strain and a control in a time-series RNA-seq experiment. We observe transcription in 542 previously un-annotated regions, of which 234 had significant changes in expression levels between the samples. Moreover, 1,791 protein-coding sequences, 80 non-coding genes, and 20 riboswitches overlapping UTR regions of coding genes had significant changes in expression. Via gene-set over-representation analysis of the differentially expressed genes, we identified putatively regulated biological processes; overall the analysis suggests that the PrsA over-expression affects ATP biosynthesis activity, amino acid metabolism, and cell wall stability. The investigation of the protein interaction network points to a potential impact on cell motility signaling. We discuss the impact of these highlighted mechanisms for reducing secretion stress or detrimental aspects of PrsA over-expression during AMY production.

Resistance gene N -mediated de novo synthesis and activation of a tobacco mitogen-activated protein kinase by tobacco mosaic virus infection (1998)

Salicylic acid-induced protein kinase (SIPK) and wounding-induced protein kinase (WIPK), two distinct members of the mitogen-activated protein (MAP) kinase family, are activated in tobacco resisting infection by tobacco mosaic virus (TMV). WIPK activation by TMV depends on the disease-resistance gene N because infection of susceptible tobacco not carrying the N gene failed to activate WIPK. Activation of WIPK required not only posttranslational phosphorylation but also a preceding rise in its mRNA and de novo synthesis of WIPK protein. The induction by TMV of WIPK mRNA and protein also occurred systemically. Its activation at the mRNA, protein, and enzyme levels was independent of salicylic acid. The regulation of WIPK at multiple levels by an N gene-mediated signal(s) suggests that this MAP kinase may be an important component upstream of salicylic acid in the signal-transduction pathway(s) leading to local and systemic resistance to TMV.
Cognitive profile and mental health in adult phenylketonuria: A PKU-COBESO study. (2017)

Adult patients had lower IQ and poorer executive functions than controls, resembling problems observed in younger patients with phenylketonuria, as well as more internalizing problems. Group differences and phenylalanine-outcome associations were smaller than those observed in younger populations. A subset of nontetrahydrobiopterin users, matched for childhood phenylalanine level, had a poorer outcome on some tests than tetrahydrobiopterin users, which might indicate an impact of tetrahydrobiopterin treatment beyond lowering phenylalanine. However, clinical relevance needs further investigation. (PsycINFO Database Record
Cleavage specificity of chloroplast and nuclear tRNA 3'-processing nucleases. (1992)

tRNAs in eukaryotic nuclei and organelles are synthesized as precursors lacking the 3'-terminal CCA sequence and possessing 5' (leader) and 3' (trailer) extensions. Nucleolytic cleavage of the 3' trailer and addition of CCA are therefore required for formation of functional tRNA 3' termini. Many chloroplast tRNA genes encode a C at position 74 which is not removed during processing but which can be incorporated as the first base of the CCAOH terminus. Sequences downstream of nucleotide 74, however, are always removed. Synthetic yeast pre-tRNA(Phe) substrates containing the complete CCA74-76 sequence were processed with crude or partially purified chloroplast enzyme fractions. The 3'-extended substrates (tRNA-CCA-trailer) were cleaved exclusively between nucleotides 74 and 75 to give tRNA-COH, whereas a 3'-mature transcript (tRNA-CCAOH) was not cleaved at all. A 5'-, 3'-extended chloroplast tRNA-CAG-trailer was also processed entirely to tRNA-COH. Furthermore, a 5'-mature, 3'-extended yeast pre-tRNA(Phe) derivative, tRNA-ACA-trailer, in which C74 was replaced by A, was cleaved precisely after A74. In contrast, we found that a partially purified enzyme fraction (a nuclear/cytoplasmic activity) from wheat embryo cleaved the 3'-extended yeast tRNA(Phe) precursors between nucleotides 73 and 74 to give tRNA(OH). This specificity is consistent with that of all previously characterized nuclear enzyme preparations. We conclude that (i) chloroplast tRNA 3'-processing endonuclease cleaves after nucleotide 74 regardless of the nature of the surrounding sequences; (ii) this specificity differs from that of the plant nuclear/cytoplasmic processing nuclease, which cleaves after base 73; and (iii) since 3'-mature tRNA is not a substrate for either activity, these 3' nucleases must require substrates possessing a 3'-terminal extension that extends past nucleotide 76. This substrate specificity may prevent mature tRNA from counterproductive cleavage by the 3' processing system.
Seismology on Venus with infrasound observations from balloon and orbit (2020)

The study of Venus' evolution is inexorably linked with studying its interior properties, which can be investigated by performing seismic studies on the planet. However, seismology on Venus has long eluded planetary scientists due to technological challenges presented by high surface temperature and pressure, which limit lifetimes of surface-based instrumentation. In this white paper, we present two complementary techniques for performing seismology on Venus by measuring the low-frequency acoustic signature (infrasound) produced by seismic activity through coupling between the solid planet and the atmosphere. These techniques may be implemented with technology available today, without the use of high-temperature electronics.

Classification and Kinematic Equivalents of Contact Types for Fingertip-Based Robot Hand Manipulation (2016)

In the context of robot manipulation, Salisbury's taxonomy is the common standard used to define the types of contact interactions that can occur between the robot and a contacted object; the basic concept behind such classification is the modeling of contacts as kinematic pairs. In this paper, we extend this notion by modeling the effects of a robot contacting a body as kinematic chains. The introduced kinematic-chain-based contact model is based on an extension of the Bruyninckx–Hunt approach of surface–surface contact. A general classification of nonfrictional and frictional contact types suitable for both manipulation analyses and robot hand design is then proposed, showing that all standard contact categories used in robotic manipulation are special cases of the suggested generalization. New contact models, such as ball, tubular, planar translation, and frictional adaptive finger contacts, are defined and characterized. An example of manipulation analysis that lays out the relevance and practicality of the proposed classification is detailed.
SUSTAINABLE DEVELOPMENT - PROBLEMS OF MEASUREMENT AND POSSIBILITIES OF REALISATION . (CASE STUDY OF NORTH - EASTERN ESTONIA) (1997)

In the middle of the century the exponentially growing mankind lived according to the popular slogan of the Mitchurin - do not ask, take from the Nature everything you need. However, environmental problems we currently encounter indicate that the carrying capacity of the Earth might be soon exhausted. Our environmental consciousness has developed from the "silent spring" through the "Limits of the Growth" to the present concept of the sustainable development. If in 70-ies the main problem seemed ; to be the limitation of the resources, then now reasonable management of the Earth, the development of harpiomous existence of the manking in the Nature is in the focus. It means that much attention is paid to defining in quantitative terms what kind of management, resource Use, style 'o f life is sustainable. Long lists of quantitative parameters, Indicators of sustainability have been proposed (1, 2). Generally speaking the use of indicators should make complicated systems understandable and predictable, to show to the society, where we are, where we are going and how to intergrate different subsystems of noosphere into a sustainable wholeness. The development of adequate set of indicators is feasible only if the noosphere is described using well-founded and syncretic system of models. One of the main goals in the nearest future would probably be formulation and analysis of the hierarchical set of models of the sustainably developing Earth, models where the "climate engine" of the planet and global economy are considered as one integrated system.
Optimal Stochastic Coded Computation Offloading in Unmanned Aerial Vehicles Network (2021)

Today, modern unmanned aerial vehicles (UAVs) are equipped with increasingly advanced capabilities that can run applications enabled by machine learning techniques, which require computationally intensive operations such as matrix multiplications. Due to computation constraints, the UAVscan offload their computation tasks to edge servers. To mitigate stragglers, coded distributed computing (CDC) based offloading can be adopted. In this paper, we propose an Optimal Task Allocation Scheme (OTAS) based on Stochastic Integer Programming with the objective to minimize energy consumption during computation offloading. The simulation results show that amid uncertainty of task completion, the energy consumption in the UAV network is minimized.
Reliability of an electromagnetic tracking system in describing pitching mechanics (2015)

The availability of various motion capture systems provides researchers and clinicians options in collecting kinematic data. However, with electromagnetic tracking systems, it is imperative to determine the reliability of the system with regard to the specific movement of interest to ensure the collection of data that are reliable, interpretable and may be generalized to a broad spectrum of individuals. Thus, the purpose of this study was to establish the reliability of an electromagnetic tracking device (ETD) in analyzing young baseball pitchers. Two data collection sessions in which throwing kinematics were recorded were conducted across a five-day span. Joint kinematics were calculated using the standards and conventions recommended by the International Shoulder Group. Correlation analyses examining inter-day reliability of the ETD showed that the system was within acceptable limits (R > .73). Throughout the selected instances of the pitch cycle, the ETD used in the current study was shown to be reliable across multiple data collection session with ICCs ranging from R = .73 to R = .86. It appears so long as set-up, sensor attachment and digitization protocols remain consistent across data collection sessions, ETD’s are a reliable tool in analyzing throwing movements in younger participants.
The σ Receptor (1988)

The psychotropic actions of opiates and opioid peptides are mediated by interaction with µ, δ, and κ opioid receptors and the related σ receptor. The µ receptor is operationally defined as the high-affinity site at which morphine-like opioids produce analgesia and other classical opioid effects. The δ receptor is operationally defined as the receptor that is found in peripheral tissues such as the mouse vas deferens (Lord et al., 1977) as well as in the CNS (Chang et al., 1979), and that exhibits a higher affinity for the naturally occurring enkephalins (shorter opioid peptides) than for morphine. The κ receptor is the receptor at which ketocyclazocine-like opioids produce analgesia as well as their unique ataxic and sedative effects (Gilbert and Martin, 1976; Martin et al., 1976). More recently it has been defined as a receptor highly selective for dynorphin, a 17-amino acid opioid peptide (Chavkin et al., 1982). Actions at all three of these sites are reversible by the specific opioid antagonist naloxone, with decreasing sensitivity going from µ to δ to κ receptors.KeywordsOpioid ReceptorOpiate ReceptorDiscriminative Stimulus EffectExcitatory Amino Acid ReceptorNarcotic AntagonistThese keywords were added by machine and not by the authors.
