The Unexpected Complexity of Filling Double-Wall Carbon Nanotubes With Nickel (and Iodine) 1-D Nanocrystals (2017)

A variety of iodine-based one-dimensional (1-D) nanocrystals were introduced into double-wall carbon nanotubes (DWCNTs) using the molten phase method, as an intermediate step for ultimately obtaining encapsulated metal nanowires. Based on high-resolution transmission electron microscopy (HRTEM) observations using different imaging modes (bright field, dark field, and scanning TEM) and associated analytical tools (electron energy loss spectroscopy), it is revealed that the reality of nanotube filling is much more complex than expected. For some iodides (typically NiI 2), earlier decomposition during the filling step was observed, which could not be anticipated from the known data on the bulk material. Other filling materials (e.g., iodine) show a variety of atomic structuration inside and outside the CNTs, which is driven by the available space being filled. Most of the encapsulated structures were confirmed by modeling.
RAN Slicing Performance Tradeoffs: Timing Versus Throughput Requirements (2022)

The coexistence of diverse services with heterogeneous requirements is a fundamental feature of 5G. This necessitates efficient <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">Radio Access Network (RAN) slicing</i> , defined as sharing of the wireless resources among diverse services while guaranteeing their throughput, timing, and/or reliability requirements. In this paper, we investigate RAN slicing for an uplink scenario in the form of multiple access schemes for two user types: (1) broadband users with throughput requirements and (2) intermittently active users with timing requirements, expressed as either Latency-Reliability (LR) or Peak Age of Information (PAoI). Broadband users transmit data continuously, hence, are allocated non-overlapping parts of the spectrum. We evaluate the trade-offs between the achievable throughput of a broadband user and the timing requirements of an intermittent user under Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA), considering capture. Our analysis shows that NOMA, in combination with packet-level coding, is a superior strategy in most cases for both LR and PAoI, achieving a similar LR with only a slight 2% decrease in throughput with respect to the case where an independent channel is allocated to each user. The latter solution leads to the upper bound in performance but requires double the amount of resources than the considered OMA and NOMA schemes. However, there are extreme cases where OMA achieves a slightly greater throughput than NOMA at the expense of an increased PAoI.
Inner and Outer Approximations of Probabilistic Sets (2014)

This paper proposes a set-membership method to characterize a probabilistic set, i.e., a set enclosing the true value for the parameter vector of a parametric system with a given probability. The approach assumes that all errors are independent and an interval for the error is known. To each error interval, a probability to be an outlier is provided. It is shown that characterizing the probabilistic set is a set inversion problem. The main contribution of the paper is to provide a method to characterize the inner part of the probabilistic set. As an illustration, an application to the static localization of a mobile robot is considered.
OntoGen extension for exploring image collections (2011)

OntoGen is a semi-automatic and data-driven ontology editor focusing on editing of topic ontologies. It utilizes text mining tools to make the ontology-related tasks simpler to the user. This focus on building ontologies from textual data is what we are trying to bridge. We have successfully extended OntoGen to work with image data and allow for ontology construction and editing on collections of labeled or unlabeled images. Browsing large heterogenous image collections efficiently is certainly a challenging task - and we feel that semiautomatic ontology construction, as described in this paper, makes this task easier.
Observation and analysis of core-penetrating Rydberg states of calcium monofluoride (1993)

Optical-optical double-resonance fluorescence excitation spectra of molecular Rydberg states of CaF are reported, and states up to 45 500 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$ above the X $^{2}\mathrm{\ensuremath{\Sigma}}^{+}$ ground state are rotationally analyzed. The new electronic states are arranged into six ``core-penetrating'' Rydberg series by fitting their energies to the Rydberg equation using effective principal quantum numbers. The ionization potential of CaF is thereby determined to be 46 998\ifmmode\pm\else\textpm\fi{}5 ${\mathrm{cm}}^{\mathrm{\ensuremath{-}}1}$. Spin-orbit, \ensuremath{\Lambda}-doubling, and spin-rotation constants are determined for a subset of the observed states. Scaling relationships for each of these fine-structure effects are developed and shown to yield characteristic scaling parameters for each series. Analysis, using ${\mathrm{Ca}}^{+}$ atomic orbitals as a basis set for the molecular Rydberg orbitals, shows that each of the six observed molecular Rydberg series correlates with a core-penetrating Rydberg series of the ${\mathrm{Ca}}^{+}$ ion, and that the p\ensuremath{\sim}d mixing suggested by the spin-orbit scaling parameters of the $^{2}\mathrm{\ensuremath{\Pi}}$ states is consistent with that previously determined for low-lying states using a ligand-field model. The spin-orbit scaling parameter for the lone $^{2}\mathrm{\ensuremath{\Delta}}$ series is consistent with pure l=2 character. In the lowest-lying state of each series, n\ensuremath{\sim}(n+1) mixing is shown to account for deviations of the molecular constants from scaling predictions based on the corresponding constants of the higher-lying states. The coefficients of scaling relations for the \ensuremath{\Lambda}-doubling and spin-rotation constants reveal interseries interactions which are consistent with substantial l mixing and which suggest that multistate perturbation and/or multichannel quantum-defect analyses should be pursued.
Input method against Trojan horse and replay attack (2010)

During a user's transactions over the Internet, there are risks of unauthorised third party transactions carried out on the user's account, using the man-in-the-middle (MITM) attack and Trojan horse. In this paper, we propose a new interactive input method of sensitive information such as credit-card numbers and account numbers against these attacks. The proposing method relatively decides the input value that a user inputs using GUI with two or more cursors which move to different directions simultaneously. The user inputs the information based on a shared secret between the user and a server beforehand, and moves one of the cursors from the shared secret to the input value, and the server changes the cursors' position and asks a question about the value which the users cursors points at. The server can decide the user's input value though the response for the question. This method is strong and does not give any hint about which cursor is used t to the attacker unless both the user and the server expose the shared value and the input value.

Syngas Production From the Reforming of Typical Biogas Compositions in an Inert Porous Media Reactor (2020)

Syngas production by inert porous media combustion of rich biogas-air mixtures was studied experimentally, focusing on carbon dioxide utilization and process efficiency. Different gas mixtures of natural gas and carbon dioxide, which simulated a typical biogas composition of 100:0, 70:30, 55:45, and 40:60 (CH<sub>4</sub>:CO<sub>2</sub>), were comparatively analyzed considering combustion waves temperatures and velocities, and chemical concentrations products, at high equivalence ratios of φ = 1.5 and φ = 2.0. Different CO<sub>2</sub> concentrations on biogas composition showed higher H<sub>2</sub> productions than on pure methane (100:0), mainly due to CO<sub>2</sub> reforming reactions. Also, syngas production, hydrogen yields, and process efficiency by means of biogas filtration combustion were higher than under methane filtration combustion. Results of the thermochemical conversion of biogas show an alternative and promising non-catalytic technique to CO<sub>2</sub> utilization.

Conception, réalisation et caractérisation de micro-miroirs à déflexion localisée appliqués aux télécommunications optiques (2002)

La demande d'acroissement des capacités des réseaux de transmission de données a fait naître un besoin en composants tout optique. Le principal objectif de cette thèse a été de mettre au point une nouvelle architecture de micro-miroir et d'en faire l'évaluation de ses performances. Celle-ci était destinée à être implantée dans des multiplexeurs-démultiplexeurs en longueurs d'ondes ou dans des routeurs optiques. Deux approches comparatives ont été menées, une analytique et une par simulation. Elles ont permis la réalisation puis la caractérisation de micro-miroirs qui sont aujourd'hui commercialisables. Pour des raisons de miniaturisation, nous nous sommes intéressé aux alimentations intégrées spécifiques nécessaires à ce type d'application. Après un état de l'art des solutions existantes pour en déduire des solutions compatibles en taille avec notre application, nous présentons notre contribution à l'avancement des travaux permettant l'obtention d'éléments passifs de stockage.
OUTSOURCING EM SERVIÇOS DE SAÚDE: um estudo de caso em hospital universitário de ensino ligado a instituição federal de ensino superior (IFES) (2016)

Nas ultimas decadas, a terceirizacao dos servicos tem se apresentado como uma tendencia economica em organizacoes de diversos setores e tamanhos. Os motivos para a adocao destas praticas sao os mais variados, indo desde aspectos financeiros, como a reducao de custos e ganho de produtividade, a aspectos administrativos e estrategicos, como a reducao do quadro de funcionarios e a reducao das atividades a serem realizadas pela organizacao. Outsourcing e uma expressao da lingua inglesa normalmente traduzida para portugues como terceirizacao. No mundo dos negocios, o outsourcing e um processo usado por uma empresa no qual outra organizacao e contratada para desenvolver uma certa area da empresa. O Estudo de caso foi realizado no HCU - Hospital de Clinicas da Universidade Federal de Uberlândia -UFU. Concluiu-se que o processo de outsourcing para o hospital foi vantajoso, entretanto um pouco dificultoso, mas que os gestores concordam que esse processo trouxe melhorias e uma significativa reducao de custos e despesas para este.

[Variations in nasal resistance in young children]. (1980)

In 22 children younger than 6 years the nasal resistance was measured at different moments of the day with the passive anterior rhinomanometer (PAR). A nasal cycle like it is found in adults was shown in 25% of the children; a partial cyclic activity was found in 31%, while in 44% a cyclic activity of the nasal resistance in both nasal cavities but in the same sense was demonstrated. Only in 2 children (out of 16) there was a total absence of cyclic phenomena. The period of the nasal cycle in young children is much shorter than in adults; the mean value we found is 1 hour 20 minutes. Physical exercises do not influence much the nasal resistance in young children. PAR in 208 nasal cavities presenting an infection showed that the nasal resistance is not much affected by nasal infections. Only a serous rhinitis with marked edema of the inferior turbinate and also a dry rhinitis with crust formation cause a distinct rise of the nasal resistance. Because of the multiple spontaneous fluctuations of the nasal resistance and because of the various influences on it, the rhinomanometric result is only a temporary result, and must therefore be interpreted with cautiousness.
Patient-Specific 3D-Printed Titanium Implant for Distal Tibial Critical Bone Defect (2022)

Aim: Post-traumatic large critical bone defects remain a challenge for today’s orthopedist. Despite multiple available options for treatment including autograft, massive allograft and various methods of bone transport, no strategy has shown itself to be free of significant complications or discouraging rates of nonunion and other mechanisms of failure. Case presentation: Here, we present a patient example of successful treatment of critical bone defect of the distal tibia utilizing the novel technology of a 3D-printed titanium cage coupled with a combination of autologous and allogenic bone graft in a 26-year-old male injured in motor vehicle collision. Conclusion: This case provides further evidence of a successful and promising new treatment to address these challenging injuries.
Progress Towards User Access Arrangements in Integrated Services Digital Networks (1982)

This paper deals with arrangements for local access to emerging Integrated Services Digital Networks (ISDN's). The ISDN concept is here introduced as the focal point for the ongoing international activity on multiservice digital networks. ISDN's are conceived as networks which have evolved from the basic digital telephone networks and they will provide end-to-end digital connectivity to support a wide range of services including voice, data, sound, and video applications. After giving a general outline of the evoving ISDN network scenarios for digital communications, the paper reviews the international trends on user access arrangements in terms of 1) user equipment and interface configurations, 2) access channel structures and information transfer capabilities, 3) local distribution plant configurations (with emphasis on the copper plant), and 4) access protocols.
High-performance magnetic active-valve micropump (2009)

We report on a high-efficiency and self-priming active-valve micropump that is magnetically actuated by arc-shaped NdFeB permanent magnets mounted on the rotation axis of a DC minimotor. For the realisation, we use affordable powder blasting microfabrication and polydimethyl-siloxane (PDMS) molding technologies. A flow rate of 1.5 mL/min and 60 mbar backpressure are obtained at the actuation resonance frequency of around 10 Hz. This performance is much better than reported so far for such type of micropump.
Drug Synergy – Mechanisms and Methods of Analysis (2012)

Toxicity and Drug Testing 144 how several drugs can reinforce each other (or why they do not). Synergy may also be observed in complex settings, such as patients receiving multiple medications. Usually, more than one biological target (protein, pathway, or even organ) are involved in such cases, and single mechanistic descriptions are not appropriate. Additional parameters to consider are drug absorption, tissue distribution, and clearance. It may be expected that many drugs interfere with metabolism of other drugs. Thus, a substance B that slows down clearance of an active drug A, say by blocking metabolizing enzymes or excretion, may lead to a higher effective concentration of A that remains in the body for a longer time. As a result, one would notice a greater effect of drug A when given together with B, although the two drugs have completely different modes of action. While certainly the combination of these two drugs would have a "combined effect is greater than the sum of their individual effects", their combination is synergistic in practical application, but not by the strict definition.
Adsorption of Pectin onto Stainless Steel Surfaces: Role of Electrostatic Interactions. (1995)

The adsorption of high methoxyl (HM) and low methoxyl (LM) pectins onto stainless steel surfaces was studied in an investigation of the fouling mechanism using nonporous stainless steel particles. The negative charge equivalents of the HM and LM pectins increased with increasing pH, and was accompanied by the charge-induced molecular expansion. HM and LM pectins could be spontaneously adsorbed on both positively and negatively charged stainless steel surfaces in a pH range of 3 to 6. The adsorption isotherms of the HM and LM pectins were similar to Langmuir-type ones. The saturation amounts of HM and LM adsorbed pectins increased with decreasing pH values and were correlated with the degree of dissociation of the carboxyl groups in the pectin molecules. While the undissociated HM and LM pectins adsorbed on stainless steel surfaces were easily released into the aqueous phase by alkali cleaning, anionic HM and LM pectins bound to positively charged stainless steel surfaces showed a high resistance to alkali cleaning. In a pH range where the HM and LM pectins and stainless steel surfaces were oppositely charged, shielding of the charges and intermolecular cross-linkage of the HM and LM pectins by monovalent or divalent cations also resulted in large amounts of pectins adsorbed and in the good release of the adsorbed pectin molecules during the alkali cleaning. It is concluded that the adsorption and desorption behavior of the pectins at the stainless steel-solution interfaces was largely determined by the electrical states of the pectin molecules and stainless steel surfaces.
Sinusoidal Input Current Discontinuous Conduction Mode Control of the VIENNA Rectifier (2016)

During light load conditions unidirectional power factor correction rectifiers, such as the VIENNA rectifier, enter discontinuous conduction mode, causing the relationship between average half-bridge voltage and duty cycle to become nonlinear and synchronously sampled current measurements not equaling the switching period average. Combined, these measurement and actuation errors result in distorted input currents at light load if no additional measures are taken. This work presents a control scheme that leads to low total harmonic distortion of the input currents in discontinuous conduction mode without relying on current measurements. The analytic expressions for the duty cycles and the threshold between discontinuous and continuous conduction mode are derived, the capability of supplying asymmetric loads is investigated and the effect on the noise spectrum relevant for the electromagnetic interference filter design is studied. Measurements of efficiency, total harmonic distortion, and conducted electromagnetic interference in discontinuous and continuous conduction mode are obtained on a 65 kW prototype operating at 290 to 530 V line-to-line RMS mains voltage range and supplying 800 V dc output voltage. The prototype, which is optimized for pulse load applications, achieves a power density of 9.56 kW/dm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> (157 W/in <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> ) and 97.2 % efficiency at full load using 650 V Si insulated gate bipolar transistor (IGBTs) with 28 kHz switching frequency.
Pathway engineering of Escherichia coli for one-step fermentative production of L-theanine from sugars and ethylamine (2020)

L-theanine is the most abundant free amino acid in tea that offers various favorable physiological and pharmacological effects. Bacterial enzyme of γ-glutamylmethylamide synthetase (GMAS) can catalyze the synthesis of theanine from glutamate, ethylamine and ATP, but the manufacturing cost is uncompetitive due to the expensive substrates and complex processes. In this study, we described pathway engineering of wild-type <i>Escherichia coli</i> for one-step fermentative production of theanine from sugars and ethylamine. First, the synthetic pathway of theanine was conducted by heterologous introduction of a novel GMAS from <i>Paracoccus aminovorans</i>. A xylose-induced T7 RNA polymerase-P <sub><i>T7</i></sub> promoter system was used to enhance and control <i>gmas</i> gene expression. Next, the precursor glutamate pool was increased by overexpression of native citrate synthase and introduction of glutamate dehydrogenase from <i>Corynebacterium glutamicum</i>. Then, in order to push more carbon flux towards theanine synthesis, the tricarboxylic acid cycle was interrupted and pyruvate carboxylase from <i>C. glutamicum</i> was introduced as a bypath supplying oxaloacetate from pyruvate. Finally, an energy-conserving phosphoenolpyruvate carboxykinase from <i>Mannheimia succiniciproducens</i> was introduced to increase ATP yield for theanine synthesis. After optimizing the addition time and concentration of ethylamine hydrochloride in the fed-batch fermentation, the recombinant strain TH11 produced 70.6 ​g/L theanine in a 5-L bioreactor with a yield and productivity of 0.42 ​g/g glucose and 2.72 ​g/L/h, respectively. To our knowledge, this is the first report regarding the pathway engineering of <i>E. coli</i> for fermentative production of theanine. The high production capacity of recombinant strain, combined with the easy processes, will hold attractive industrial application potential for the future.

Theoretical Resolution of Computed Tomography Systems (1979)

A simple analytic model is presented which is used to calculate the impulse response of a computed tomography system for parametric variations of the geometry. The model is useful for fan beam as well as parallel beam geometries. Results show that wide-aperture detector systems have intrinsic resolution limitations that are not mitigated by oversampling. Furthermore, the optimum focal spot size of the X-ray source is found to be dependent on the detector geometry.
