An HTTP/2 push-based framework for low-latency adaptive streaming through user profiling (2018)

Web portals, such as the one hosted by news providers, have recently started to provide significant amounts of multimedia content. To deliver this content over the best-effort Internet, HTTP Adaptive Streaming (HAS) is generally used, allowing smoother playback and a better Quality of Experience (QoE). To stimulate user engagement with the provided content, reducing the video's startup time has become more and more important: while the current median video load time is in the order of seconds, research has shown that user waiting times must remain below two seconds to achieve an acceptable QoE. In this work, we present a framework for low-latency delivery of news-related video content, integrating four optimizations either at server-side, client-side, or at the application layer. Most importantly, we propose to identify relevant content through user profiling, using proactive delivery and client-side caching to reduce the video startup time. By means of a large data set from a Belgian news provider, we show that the proposed framework can reduce the startup time from 4.6 s to 1.5 s (-74.6%) in a 3G scenario, at the cost of limited network overhead and additional complexity at server- and client-side.
Investigation of Ductile Fracture Mechanism in Multipass Drawing of Hollow Specimen (2020)

To apply hollow forming technology for car parts, it is necessary to understand the ductile fracture mechanism of hollow forming. In this study, the cold drawing test and the finite element method analysis (FEM) of hollow specimens were carried out. It was clarified that the ductile fracture of hollow specimens in cold drawing was affected by both stress triaxiality and Lode angle parameter. As a result of fracture observation of a hollow specimen, an equiaxed dimple and an elongated dimple were observed. A mixed-mode ductile fracture mechanism (shear deformation of voids and typical void growth and coalescence) for hollow specimens in cold drawing is assumed.

1H electron-nuclear double resonance of cobalt hemoglobin. (1982)

Proton 1H electron-nuclear double resonance spectra were obtained from cobalt-substituted hemoglobin A. For oxy cobalt-substituted hemoglobin (CoHb), two major couplings were found. One is exchangeable by deuterium and has a coupling of approximately 5.6 MHz which is assigned to the N epsilon 2-proton of the distal histidine (E7), interacting with the ligand. The other splitting (approximately 2.4-3.2 MHz) is attributed to a methyl-proton on Val (E11). No coupling of protons on the proximal side is resolved. Deoxy CoHb exhibits only one prominent interaction (approximately 1.3 MHz) which is assigned to one of the protons on the proximal histidine (F8). The influence of the distal amino acids His (E7) and Val (E11) on the ligand affinity in oxy CoHb is discussed.
Trends on the application of emerging nonvolatile memory to processors and programmable devices (2013)

A number of non-volatile memory technologies (NVMs) emerged in the past years. They promise to cope with limitations of standard memory technologies, such as scalability and idle power consumption. Numerous logic circuits based on these emerging technology have been proposed and prototyped in the last years. In this paper, we present an overview and current status of these logic circuits and discuss their potential applications in this field. In the first part, this article provides a survey on the application of those memories to programmable devices. The second section is dedicated to the use of NVMs in the processor's memory hierarchy, where we discuss potential applications based on a preliminary study we performed. Results were obtained using TAS-MRAM NVM technology.
Radical cation formation in characterization of novel C3‐symmetric disks and their precursors by matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (2006)

Four C3-symmetrical tris(dipeptide) disks and their precursors were characterized using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI TOF MS). The C3-symmetrical disks were based on a benzene-1,3,5-triscarboxamide core extended by oligopeptides with trialkoxyanilide tails. The results indicate that MALDI TOF MS is a powerful and straightforward analytical technique for characterizing C3-symmetrical disks and their precursors. Clear (pseudo)-molecular ion peaks could readily be identified. It is remarkable that strong radical ion signals were observed for all the compounds, including the anilines that were expected to be protonated prior to laser irradiation using acidic MALDI matrixes. Possible mechanisms for radical ion formation were investigated with the employment of radical scavengers, with various matrixes and with direct laser desorption/ionization (LDI). Most likely the radicals are formed by losing one electron from the aniline nitrogen and stabilized by conjugation through the phenyl ring. It appears that direct photo/thermal ionization of analytes is an important route for the radical ion formation of the compounds with trialkoxy aniline/anilide groups.
Toward affective dialogue management using partially observable Markov decision processes (2008)

Designing and developing affective dialogue systems have recently received much interest from the dialogue research community. A distinctive feature of these systems is affect modeling. Previous work was mainly focused on showing system's emotions to the user in order to achieve the designer's goal such as helping the student to practice nursing tasks or persuading the user to change their dietary behavior. A challenging problem is to infer the user's affective state and to adapt the system's behavior accordingly. This thesis addresses this problem from an engineering perspective using Partially Observable Markov Decision Process (POMDP) techniques and a Rapid Dialogue Prototyping Methodology (RDPM). We argue that the POMDPs are suitable for use in designing affective dialogue management models for three main reasons. First, the POMDP model allows for realistic modeling of the user's affective state, the user's intention, and other (user's) hidden state components by incorporating them into the state space. Second, recent dialogue management research has shown that the POMDP-based dialogue manager is able to cope well with uncertainty that can occur at many levels inside a dialogue system from speech recognition, natural language understanding to dialogue management. Third, the POMDP environment can be used to create a simulated user which is useful for learning and evaluation of competing dialogue strategies. In the first part of this thesis, we first present the RDPM for a quick production of frame-based dialogue models for traditional (i.e., non-affect sensitive) singleapplication dialogue systems. The usability of the RDPM has been validated through the implementation of several prototype dialogue systems. We then present a novel approach to developing interfaces for multi-application systems which are dialogue systems that allow the user to navigate between a large set of applications smoothly and transparently. The work in this part provides an essential infrastructure for implementing our prototype POMDP-based dialogue manager. In the second part, we first describe a factored POMDP approach to affective dialogue management. This approach illustrates that POMDPs are an elegant model for building affective dialogue systems. Further, the POMDP-based dialogue strategy outperforms all other known strategies from the literature when tested with smallscale dialogue problems. However, a well-known drawback of POMDP-based dialogue managers is that computing a near-optimal dialogue policy is extremely computationally expensive. We then propose a tractable hybrid DDN-POMDP method to tackle many of these scalability problems. The central contribution of our method (com- pared with other POMDP-based dialogue management methods from the literature) is the ability to handle frame-based dialogue problems with hundreds of slots and hundreds of slot values. Keywords: dialogue modeling, dialogue management, dialogue systems, rapid prototyping, partially observable Markov decision processes, multimodal, multi-application, multi-domain, affective computing.
Thiamine responsive pyruvate dehydrogenase deficiency in an adult with peripheral neuropathy and optic neuropathy (2008)

Pyruvate dehydrogenase complex (PDHc) is a thiamine dependent key enzyme for energy production which catalyses decarboxylation of pyruvate into acetyl CoA for the Krebs cycle.1 PDHc deficiency is generally (80%) caused by mutations in the E1α subunit gene, PDHA1 , located on chromosome Xp22.1, but other genes have been reported to be mutated (eg, PDHX , encoding the E3 binding protein, DLAT , encoding the E2 subunit PDHX, and PDHB , encoding the E1 beta subunit). The disease usually presents with lactic acidosis, psychomotor retardation and Leigh syndrome leading to death or severe handicap in infancy or childhood.1 Mild forms, compatible with surviving into adulthood, have rarely been reported.

A 26-year-old man was born at 8 months’ gestation, following maternal eclampsia. His psychomotor development was normal. From the age of 2 years he suffered from paroxysmal walking difficulties that appeared exclusively during fever episodes. These “crises” lasted from several hours to days during which he experienced limb weakness and ataxia. One episode was remarkable for blurring of consciousness and another for external ophthalmoplegia. Episodes persisted until adulthood at a frequency of approximately 1 per year. In between crises, the patient had kyphoscoliosis, absent tendon reflexes, pes cavus and mild …
Synthesis and aromatisation of cyclic enediyne-containing amino acids (2008)

A series of cyclic enediyne-containing amino acids with ring sizes varying from 10 to 12 atoms have been prepared starting from propargylglycine and homopropargylglycine. Their reactivity towards Bergman cyclisation under elevated temperatures has been explored. The enediynes displayed marked differences in cyclisation half-lives depending on the olefinic substituent and the ring size. A potential candidate for incorporation into peptides has been identified.

Instrumentation for the recording and digital processing of multichannel ECG data (1992)

A 64 channel isolated front-end with small dimensions is described. A nearly perfect isolation is obtained by using an optical fiber link and battery power which makes a high quality recording possible with very little susceptibility to interference. The signals are A/D converted in the front-end and easy interfacing has been developed to standard microcomputers using commercially available DMA-boards.
Development of the Scope of a Co-Mediated O→C Rearrangement Reaction (2005)

[reaction: see text] In this paper we describe an Al-promoted, Co-mediated O-->C rearrangement reaction of cyclic enol ethers. This process delivers functionalized cyclohexanones with good to excellent levels of diastereocontrol, whereby the product stereochemistry is dependent on the E/Z-stereochemistry of the starting enol ether. The rearrangement process also permits access to highly substituted alpha-spirocyclic cyclohexanones as well as cyclopentanones. The latter rearrangement appears to proceed via an unusual 5-(enolendo)-exo-trig cyclization process.
DESIGN METHODOLOGY FOR PORTAL FRAMES OF BUILDING STRUCTURES UNDER HORIZONTAL FORCES. PARTICULAR CASE ANALYSED (2020)

In this paper an analysis of building frames under horizontal actions is presented. Firstly the theoretical behavior is studied, and then a strut and ties model is proposed based on results obtained in an auxiliary finit element model. Thus, it has been first described the particular features of the structural problem, on the one hand the seismic action and on the other structural mechanism that it involves. Then a particular analysis of a node has been carried out, in the case of a frame with a specific configuration. This fem model allows to check the hypothesis adopted for the strut and ties calculations that are proposed as the solution of the problem. In this way, the main intention of this article is not to show a general approach to the issue of portal frames under seismic forces. Instead of this, the main goal of this paper is to propose a methodology based on simple calculation models that let solve the structural problem.
L'Année de la régulation n° 8 (2004-2005) (2004)

Ce texte vise à montrer que des modes de gouvernance locale de l’économie émergent sur le territoire français de manière dynamique et désordonnée. La France ne devient pas l’Italie mais des cas intéressants de modes de gouvernance territorialisées émergent. Ensuite, l’article tente d’expliquer ces évolutions, y compris l’absence de districts industriels de type italien, en partant des biens et des services dont ont besoin les PMI pour se développer, soit la notion de biens collectifs locaux de concurrence. Le problème des PMI est souvent celui de l’isolement et l’accès à des biens et des services qui les rendent compétitives face aux grandes firmes. Le succès des PMI ou des réseaux de PMI dépend de l’accès à ces différents biens et services qui ont souvent une dimension collective d’où la notion de « biens collectifs locaux de concurrence » (BCLC) qui sera définie et utilisée dans ce texte. Enfin, ces BCLC n’apparaissent pas au hasard, leur production dépend de l’existence de modes de gouvernance locale qui prennent des formes diverses. L’analyse de la production des BCLC pour les PMI sur une base territoriale explique en partie le dynamisme et le type de systèmes productifs locaux dans différents environnements.

Decompositions of general quantum gates (2005)

Quantum algorithms may be described by sequences of unitary transformations called quantum gates and measurements applied to the quantum register of n quantum bits, qubits. A collection of quantum gates is called universal if it can be used to construct any n-qubit gate. In 1995, the universality of the set of one-qubit gates and controlled NOT gate was shown by Barenco et al. using QR decomposition of unitary matrices. Almost ten years later the decomposition was improved to include essentially fewer elementary gates. In addition, the cosine-sine matrix decomposition was applied to efficiently implement decompositions of general quantum gates. In this chapter, we review the different types of general gate decompositions and slightly improve the best known gate count for the controlled NOT gates to (23/48)4^n in the leading order. In physical realizations, the interaction strength between the qubits can decrease strongly as a function of their distance. Therefore, we also discuss decompositions with the restriction to nearest-neighbor interactions in a linear chain of qubits.
Joint Scheduling and Resource Allocation in the OFDMA Downlink: Utility Maximization Under Imperfect Channel-State Information (2011)

We consider the problem of simultaneous user-scheduling, power-allocation, and rate-selection in an orthogonal frequency division multiple access (OFDMA) downlink, with the goal of maximizing expected sum-utility under a sum-power constraint. In doing so, we consider a family of generic goodput-based utilities that facilitate, e.g., throughput-based pricing, quality-of-service enforcement, and/or the treatment of practical modulation-and-coding schemes (MCS). Since perfect knowledge of channel state information (CSI) may be difficult to maintain at the base-station, especially when the number of users and/or subchannels is large, we consider scheduling and resource allocation under imperfect CSI, where the channel state is described by a generic probability distribution. First, we consider the “continuous” case where multiple users and/or code rates can time-share a single OFDMA subchannel and time slot. This yields a nonconvex optimization problem that we convert into a convex optimization problem and solve exactly using a dual optimization approach. Second, we consider the “discrete” case where only a single user and code rate is allowed per OFDMA subchannel per time slot. For the mixed-integer optimization problem that arises, we discuss the connections it has with the continuous case and show that it can solved exactly in some situations. For the other situations, we present a bound on the optimality gap. For both cases, we provide algorithmic implementations of the obtained solution. Finally, we study, numerically, the performance of the proposed algorithms under various degrees of CSI uncertainty, utilities, and OFDMA system configurations. In addition, we demonstrate advantages relative to existing state-of-the-art algorithms.
Two-photon microscopy with dynamic focusing objective using a liquid lens (2010)

A variable focus microscope without moving parts for axial focusing within the sample in two-photon microscopy can provide a faster, more robust, and cost-effective solution to 3D imaging at high resolution. A custom dynamic focusing objective was recently developed that incorporates a liquid lens within the optical design of a custom microscope. In this paper, we investigate the use of a liquid lens embedded in an aberration-corrected custom microscope for z-dimension scanning in 3D resolved two-photon microscopy. Results show that we can achieve imaging speed of 50 frames per sec for an arbitrary plane in 3D space, a leap forward in scan speed for two-photon microscopy.

Synthesis and properties of boron complexes of [14]triphyrins(2.1.1) (2013)

Boron complexes of [14]triphyrins(2.1.1) were prepared from free-base [14]triphyrins(2.1.1) with phenylboron dichloride. The absorption spectrum of the meso-free β-alkyl-triphyrin boron complex in CH2Cl2 showed a broad weak band at around 640 nm assigned to transition from B-phenyl to the triphyrin, while that of the meso-aryl benzotriphyrin boron complex showed only Soret and Q bands.
Xanthomonas sinensis Cell Wall Lipopolysaccharide (1972)

Abstract Mild acid hydrolysis of the cell wall lipopolysaccharide from Xanthomonas sinensis yielded a disaccharide composed of mannose phosphate glycosidically linked to a keto-deoxy acid. Treatment of the disaccharide with alkaline phosphatase followed by α-mannosidase liberated an acid component which migrated electrophoretically with authentic 3-deoxy-d-manno-octulosonic acid (KDO), but differed chromatographically from known KDO. Molecular weight determination by mass spectrometry of the persilylated derivative of the borohydride-reduced acid yielded a value equal to that calculated for the lactone of authentic reduced KDO. Periodate oxidation followed by borohydride reduction of the Xanthomonas acid yielded two electrophoretically separable compounds. Molecular weight determinations by high resolution mass spectrometry indicated that one of these compounds had gained 2 atomic mass units, while the other had lost 100 atomic mass units from the starting material. Treatment of authentic KDO with 2% acetic acid for 90 min at 100° followed by borohydride reduction resulted in the conversion of most of the KDO into compounds identical with the reduced acids isolated from the Xanthomonas lipopolysaccharide. The results presented are consistent with the conclusion that the lipopolysaccharide occurring in the cell wall of Xanthomonas sinensis contains a single molecule of 3-deoxy-d-manno-octulosonic acid per molecule of lipopolysaccharide, and that mild acid hydrolysis of either the Xanthomonas lipopolysaccharide or of authentic KDO results in the formation of 4,7-anhydro- and 4,8-anhydro-3-deoxy-octulosonic acid.
Microwave-Assisted Pyrolysis of Pine Wood Sawdust Mixed with Activated Carbon for Bio-Oil and Bio-Char Production (2020)

Pyrolysis of pine wood sawdust was carried out using microwave-heating technology in the presence of activated carbon (AC). Experimental conditions were of 20 min processing time, 10 wt.% of AC, and a microwave power varying from 100 to 800 W. The results obtained showed that the microwave absorber allowed increasing the bio-oil yield up to 2 folds by reducing the charcoal fraction. The maximum temperature reached was 505 °C at 800 W. The higher heating values (HHV) of the solid residues ranged from 17.6 to 30.3 MJ/kg. The highest HHV was obtained for the sample heated at 800 W with 10 wt.% of AC, which was 33% higher than the non-charged sample heated at the same power. Furthermore, the addition of AC allowed showing the probable catalytic effect of the AC in the charged sample pyrolysis bio-oils.
