Abstract:
A communication is energy efficient when the communicating peers are near to each other or where the separating distances are short and the LOS component is a dominant one. The channel conditions in wireless communication vary with respect to time and distance. Let us consider a scenario where a terminal X is communicating to another terminal Y in a shadowed fading environment through an access point (AP) or a base station (BS). Supposing that the terminal X is at the border of the transmission range of BS, any slight movement of the terminal X may result in either degradation of the wireless channel between terminal X and BS or totally getting out of transmission radius of BS. The MAC layer of BS fails to receive the error-free packet as a result. The BS does not send back the ACK packet to the source terminal X. After waiting for a time specified, the source starts retransmitting the packet. If the source terminal does not receive the ACK packet even after a threshold number of retransmissions (RetryLimit), the source discards the packet. An efficient and reliable scheme of retransmission is proposed in this paper by using STBC based relay transmission system. MATLAB is used for simulation purpose and the results generated for direct and cooperative transmissions are compared in terms of the link layer parameter PER.

Abstract:
In digital communication systems, ARQ and HARQ schemes are employed in order to ensure efficient transmission of information and utilisation of the channel by retransmitting information that has not being received correctly at the receiver. In some applications, however, such as real-time services, the quality of information is degraded if too many retransmission trials are employed for each unit of erroneously received information. The retransmissions are therefore limited leading to truncated ARQ and HARQ schemes. In this study we develop a new method for deriving the expressions for the throughput efficiencies of truncated ARQ and HARQ schemes and investigate how the efficiencies vary with the number of allowed retransmissions. Keywords: ARQ, HARQ, Throughput Efficiency, Truncated ARQ.

Abstract:
When designing architectures and protocols for data traffic requiring real-time services, one of the major design goals is to guarantee that traffic deadlines can be met. However, many real-time applications also have additional requirements such as high throughput, high reliability, or energy efficiency. High-performance embedded systems communicating heterogeneous traffic with high bandwidth and strict timing requirements are in need of more efficient communication solutions, while wireless industrial applications, communicating control data, require support of reliability and guarantees of real-time predictability at the same time. To meet the requirements of high-performance embedded systems, this thesis work proposes two multi-wavelength high-speed passive optical networks. To enable reliable wireless industrial communications, a framework in­corporating carefully scheduled retransmissions is developed. All solutions are based on a single-hop star topology, predictable Medium Access Control algorithms and Earliest Deadline First scheduling, centrally controlled by a master node. Further, real-time schedulability analysis is used as admission control policy to provide delay guarantees for hard real-time traffic. For high-performance embedded systems an optical star network with an Arrayed Waveguide Grating placed in the centre is suggested. The design combines spatial wavelength re­use with fixed-tuned and tuneable transceivers in the end nodes, enabling simultaneous transmis­sion of both control and data traffic. This, in turn, permits efficient support of heterogeneous traf­fic with both hard and soft real-time constraints. By analyzing traffic dependencies in this mul­tichannel network, and adapting the real-time schedulability analysis to incorporate these traffic dependencies, a considerable increase of the possible guaranteed throughput for hard real-time traffic can be obtained. Most industrial applications require using existing standards such as IEEE 802.11 or IEEE 802.15.4 for interoperability and cost efficiency. However, these standards do not provide predict­able channel access, and thus real-time guarantees cannot be given. A framework is therefore de­veloped, combining transport layer retransmissions with real-time analysis admission control, which has been adapted to consider retransmissions. It can be placed on top of many underlying communication technologies, exemplified in our work by the two aforementioned wireless stan­dards. To enable a higher data rate than pure IEEE 802.15.4, but still maintaining its energy saving properties, two multichannel network architectures based on IEEE 802.15.4 and encompassing the framework are designed. The proposed architectures are evaluated in terms of reliability, utiliza­tion, delay, complexity, scalability and energy efficiency and it is concluded that performance is enhanced through redundancy in the time and frequency domains.

Wen, Lan. "Methods for handling missing data in cohort studies where outcomes are truncated by death." Thesis, University of Cambridge, 2018. https://www.repository.cam.ac.uk/handle/1810/278788.

Full text
Abstract:
This dissertation addresses problems found in observational cohort studies where the repeated outcomes of interest are truncated by both death and by dropout. In particular, we consider methods that make inference for the population of survivors at each time point, otherwise known as 'partly conditional inference'. Partly conditional inference distinguishes between the reasons for missingness; failure to make this distinction will cause inference to be based not only on pre-death outcomes which exist but also on post-death outcomes which fundamentally do not exist. Such inference is called 'immortal cohort inference'. Investigations of health and cognitive outcomes in two studies - the 'Origins of Variance in the Old Old' and the 'Health and Retirement Study' - are conducted. Analysis of these studies is complicated by outcomes of interest being missing because of death and dropout. We show, first, that linear mixed models and joint models (that model both the outcome and survival processes) produce immortal cohort inference. This makes the parameters in the longitudinal (sub-)model difficult to interpret. Second, a thorough comparison of well-known methods used to handle missing outcomes - inverse probability weighting, multiple imputation and linear increments - is made, focusing particularly on the setting where outcomes are missing due to both dropout and death. We show that when the dropout models are correctly specified for inverse probability weighting, and the imputation models are correctly specified for multiple imputation or linear increments, then the assumptions of multiple imputation and linear increments are the same as those of inverse probability weighting only if the time of death is included in the dropout and imputation models. Otherwise they may not be. Simulation studies show that each of these methods gives negligibly biased estimates of the partly conditional mean when its assumptions are met, but potentially biased estimates if its assumptions are not met. In addition, we develop new augmented inverse probability weighted estimating equations for making partly conditional inference, which offer double protection against model misspecification. That is, as long as one of the dropout and imputation models is correctly specified, the partly conditional inference is valid. Third, we describe methods that can be used to make partly conditional inference for non-ignorable missing data. Both monotone and non-monotone missing data are considered. We propose three methods that use a tilt function to relate the distribution of an outcome at visit j among those who were last observed at some time before j to those who were observed at visit j. Sensitivity analyses to departures from ignorable missingness assumptions are conducted on simulations and on real datasets. The three methods are: i) an inverse probability weighted method that up-weights observed subjects to represent subjects who are still alive but are not observed; ii) an imputation method that replaces missing outcomes of subjects who are alive with their conditional mean outcomes given past observed data; and iii) a new augmented inverse probability method that combines the previous two methods and is doubly-robust against model misspecification.

Abstract:
Le processus de recombinaison V(D)J des gènes d’immunoglobulines (Ig) est caractérisé par une grande imprécision des jonctions entre les segments variables (V), de diversité (D) et de jonction (J). Deux fois sur trois, un décalage du cadre de lecture apparaît, aboutissant à une jonction non productive dite « hors phase ». Plusieurs études ont démontré que les deux allèles productifs et non-productifs sont activement transcrits. Les transcrits matures issus des allèles non-productifs sont pris en charge par un mécanisme de surveillance des ARNm appelé NMD « Nonsense-Mediated mRNA Decay ». En dégradant efficacement les ARNm d’Ig contenant des codons non-sens, ce mécanisme prévient l’apparition des Ig tronquées au cours de l’ontogénie B. Néanmoins, aucune étude n’a jusqu’ici analysé l’impact de l’épissage alternatif des transcrits d’Ig non-productifs. Ce phénomène appelé NAS « Nonsense-associated Altered Splicing » peut conduire à une production d’Ig tronquées présentant des délétions internes du domaine variable (V).Les projets développés lors de cette thèse ont montré que la présence d’un codon non-sens, au niveau de l’exon variable (VJ) des transcrits Igκ, favorise le saut d’exon et la production de chaînes légères dépourvues de domaine variable (ΔV-κLCs). De façon intéressante, ces Ig tronquées provoquent un stress cellulaire et conduisent à l’apoptose des plasmocytes (Article 1). Ces observations ont permis d’identifier un nouveau point de contrôle agissant tardivement lors de la différenciation plasmocytaire : le TIE « Truncated-Ig Exclusion » checkpoint. Ce processus de contrôle provoque l’élimination des plasmocytes qui produisent des chaînes d’Ig tronquées. Nous avons également étudié l’épissage alternatif des transcrits d’Ig non-productifs en l’absence de TIE-checkpoint (Article 2). Cette étude a révélé que l’hypertranscription des gènes d’Ig dans les plasmocytes favorise l’épissage alternatif des transcrits d’Ig non-productifs. En utilisant un modèle d’expression forcée d’Ig tronquées, nous avons mis en évidence une coopération entre les mécanismes assurant la surveillance des ARNm (NMD) et la surveillance au niveau protéique (UPR : « Unfolded Protein Response », autophagie) (Article 3). Sur la base de ces résultats, nous avons mis au point une nouvelle approche thérapeutique qui consiste à forcer la production d’Ig tronquées en utilisant des oligonucléotides anti-sens (AON) capables de provoquer l’élimination de l’exon variable lors de l’épissage. Cette invention pourrait ouvrir des perspectives thérapeutiques pertinentes dans le traitement du Myélome Multiple et d’autres pathologies touchant les plasmocytes
The recombination process V(D)J of immunoglobulin (Ig) genes is characterized by random junctions between the variable (V), diversity (D) and joining (J) segments. A frameshift mutation appears in two-third of cases, generating a non-productive or « out of frame » junction. Several studies have shown that both productive and non-productive alleles are actively transcribed. The mature transcripts from nonproductive alleles are usually considered sterile and innocuous as a result of an mRNA surveillance mechanism called NMD « Nonsense-Mediated mRNA Decay ». By degrading aberrant mRNA, this mechanism prevents the appearance of truncated Ig during B cell ontogeny. However, less is known about the impact of alternative splicing on non-productive Ig transcripts. This mechanism, called NAS « Nonsense-associated Altered Splicing » can lead to the production of truncated Ig with internal deletions of variable domain (V). During my thesis, we have shown that the presence of a stop codon, within the variable exon (VJ) of Igκ transcripts, promotes exon skipping and synthesis of V domain-less κ light chains (ΔV-κLCs). Interestingly, such truncated Ig causes cellular stress and leads to plasma cells apoptosis (Article 1). These findings have identified a new checkpoint acting late during plasma cell differentiation: TIE « Truncated-Ig Exclusion » checkpoint. This process ensures counter-selection of plasma cells producing truncated-Ig. We also studied the alternative splicing of non-productive Ig transcripts in the absence of TIE-checkpoint (Article 2). We found that hypertranscription of Ig genes in plasma cells promote alternative splicing of non-productive Ig transcripts. Using a model forcing the expression of truncated Ig, we identified a cooperative action between mRNA surveillance mechanisms (NMD) and those of protein surveillance (UPR « Unfolded Protein Response », autophagy) (Article 3). Based on these results, we have developed a new therapeutic approach by increasing the production of truncated Ig using antisense oligonucleotides (AON) that leads to the elimination of the variable exon during splicing. This invention could open new avenues for the treatment of Multiple Myeloma patients and other pathologies affecting plasma cells

In this paper, we add transmit power control within each AMC mode for the cross-layer combining AMC and ARQ for OFDM system. Our scheme that subjects to power constraint in each AMC mode is different from the scheme of the other paper that subject to power constraint averaged over all AMC modes. Also the other paper is a single-carrier system. Numerical results reveal that in the system, the average SE of our proposed scheme is better than the non-adaptive case.

This chapter concentrates on practical tips and tricks for improving the efficiency of computer simulation programs. This includes the effect of using truncated and shifted potentials, and the use of table look-up and neural networks for calculating potentials. Approaches for speeding up simulations, such as the Verlet neighbour list, linked-lists and multiple timestep methods are described. The chapter then proceeds to discuss the general structure of common simulation programs; in particular the choice of the starting configuration and the initial velocities of the particles. The chapter also contains details of the overall approach to organising runs, storing the data, and checking that the program is working correctly.

What is the lived experience of the black male body within the context of white America in the twenty-first century? How can we describe the deep existential and psychic dimensions of black male bodies as they negotiate their lives within the context of white hegemony? How do their bodies continue to be truncated according to a distorted and racist imago in the white imaginary? The black male body, within the context of this white imaginary, constitutes a site of “contamination.” As such, then, within the white body politic, black male bodies are thereby always already targets of the state, deemed “criminals,” “monsters,” and “thugs.” Textual testimony, coupled with social, political, and existential phenomenological analyses, demonstrates the sheer gravity of being black and male in a mythical postrace America.

Abstract:
This book is an introduction to statistical field theory, which is an important subject within theoretical physics and a field that has seen substantial progress in recent years. The book covers fundamental topics in great detail and includes areas like conformal field theory, quantum integrability, S-matrices, braiding groups, Bethe ansatz, renormalization groups, Majorana fermions, form factors, the truncated conformal space approach and boundary field theory. It also provides an introduction to lattice statistical models. Many topics are discussed at a fairly advanced level but via a pedagogical approach. In particular, the book presents in a clear way non-perturbative methods of quantum field theories that have become decisive tools in many different areas of statistical and condensed matter physics, and which are currently an essential foundation of the working knowledge of a modern theoretical physicist.

Stölzel, Gottfried Heinrich. Die leidende und am Creutz sterbende Liebe Jesu. Edited by Warwick Cole. A-R Editions, 2020. http://dx.doi.org/10.31022/b214.

Full text
Abstract:
Gottfried Heinrich Stölzel (1690–1749) was a highly respected musician and composer who contributed works in all major eighteenth-century musical genres. His first Passion, Die leidende und am Creutz sterbende Liebe Jesu, was performed widely during his lifetime, including by Bach in the same year he composed his Christmas Oratorio, which imitates various aspects of Stölzel's style. There are several characteristics of Stölzel's Passion that demonstrate the composer's unusual approach to the genre, including a lack of named protagonists, texts couched in the present tense to heighten the immediacy of the drama, a balance between recitatives and arias, and the employment of primarily seventeenth-century chorales with plain harmonizations that may have encouraged the participation of the listening congregation. Evidence of the Passion's popularity is evident from the existence of a truncated and adapted mid-eighteenth century score, several excerpts of which are included in the edition's appendix.

Abstract:
Decades ago, ethnomethodologists discovered that under routine conditions, individuals cling to what sociologists have called “markers of certainty.” This sense of certainty is challenged once individuals are displaced from their home societies and find themselves detached from their routine social, political, and cultural environment. This chapter starts by addressing the question of the transformational impact of the exilic experience on the minds and networks of exiles. It examines some of the major impacts that those exiles, expatriates, sojourners, and migrants had and continue to have on their home societies. The chapter addresses the impact of exile on people’s lives and on their fractured experiences, the debates and prospects of return, and the challenges of dis-exile and postexilic trends. It also examines the long-term impact on children and the challenges of truncated returns and cosmopolitan outlooks.

Abstract:
The pulmonary oxygen uptake (pV̇O2) kinetic response to exercise provides valuable non-invasive insight into the control of oxidative phosphorylation and determinants of exercise tolerance in children and adolescents. Few methodologically robust studies have investigated pV̇O2 kinetics in children and adolescents, but age- and sex-related differences have been identified. There is a clear age-related slowing of phase II pV̇O2 kinetics during heavy and very heavy exercise, with a trend showing during moderate intensity exercise. During heavy and very heavy exercise the oxygen cost is higher for phase II and the pV̇O2 component is truncated in children. Sex-related differences occur during heavy, but not moderate, intensity exercise, with boys having faster phase II pV̇O2 kinetics and a smaller pV̇O2 slow component compared to girls. The mechanisms underlying these differences are likely related to changes in phosphate feedback controllers of oxidative phosphorylation, muscle oxygen delivery, and/or muscle fibre recruitment strategies.

Full text
Abstract:
Attenuation correction minimizes the impact of body habitus on the acquired myocardial count distribution. The superior diagnostic performance of corrected over uncorrected SPECT images is due to improved specificity and normalcy rate. The transmission image used for attenuation correction is obtained using CT or Gd-153 line sources. Artifactual defects may develop with attenuation correction if the transmission image is truncated, of poor count density, significantly contaminated by downscatter or misregistered with the emission image. Attenuation correction can help decrease the radiation exposure to the patient and improve the workflow in the nuclear laboratory by obviating the need for rest imaging on stress-first myocardial perfusion SPECT protocols. Coronary calcium on the CT attenuation image can add diagnostic and prognostic value to normal myocardial perfusion SPECT in patients without known coronary artery disease. Incidental noncardiac findings of potential clinical relevance are frequently found on the CT attenuation image and should be described on the clinical report.

Abstract This work investigates the interaction of the afterbody flow with the propulsive jet flow on a generic space launcher equipped with two alternative nozzle concepts and different afterbody geometries. The flow phenomena are characterized by experimental measurements and numerical URANS and LES simulations. Investigations concern a configuration with a conventional truncated ideal contour nozzle and a configuration with an unconventional dual-bell nozzle. In order to attenuate the dynamic loads on the nozzle fairing, passive flow control devices at the base of the launcher main body are investigated on the configuration with TIC nozzle. The nozzle Reynolds number and the afterbody geometry are varied for the configuration with dual-bell nozzle. The results for integrated nozzles show a shift of the nozzle pressure ratio for transition from sea-level to altitude mode to significant lower levels. The afterbody geometry is varied including a reattaching and non-reattaching outer flow on the nozzle fairing. Investigations are performed at supersonic outer flow conditions with a Mach number of $$Ma_\infty =3$$. It turns out, that a reattachment of the outer flow on the nozzle fairing leads to an unstable nozzle operation.

Abstract:
In this chapter, we are interested in the numerical resolution of the mixed BBM-KdV equation defined in unbounded domain. Boundary Element Method (BEM) are introduced to truncate the equation into a considered bounded domain. BEM uses domain decomposition techniques to construct Boundary Condition (BC) as transmission between the bounded domain and its complementary. We then present a suitable approximation of these BC using Discrete Galerkin Method. Numerical simulations are made to show the efficiency of these BC. We also compare with another method that truncates the equation from unbounded to bounded domain, called Non Standard Boundary Conditions (NSBC) which introduces new variables to catch information at the boundary and compose a system to connect all these variables in the bounded domain. Further discussions are made to highlight the advantages of each method as well as the difficulties encountered in the numerical resolution.

This chapter focuses on noise processes in discrete communication systems. The problem with white Gaussian noise process discretization is that a strict definition implies that the noise has theoretically infinite power. Thus, it would be impossible to generate discrete noise, because the sampling theorem requires that the sampled signal must be physically realizable, that is, the sampled noise needs to have a finite power. To overcome this problem, noise entropy is defined as an additional measure of noise properties, and a truncated Gaussian probability density function is used. Adding entropy and truncated density to the definition of the noise autocorrelation and power spectral density functions allows mathematical modelling of the discrete noise source for both baseband and bandpass noise generators and regenerators. Noise theory and noise generators are essential for a theoretical explanation of the operation of digital and discrete communications systems and their design, simulation, emulation, and testing.

Abstract:
In this article, a performance evaluation of the Chinese Professional Baseball League (CPBL) was conducted from a human resources (HR) perspective. Two important aspects were included: (1) a comprehensive evaluation of the competition performance of the professional baseball teams in international games and regular season games; and (2) the data envelopment analysis (DEA) and “two-stage” methodologies, which were employed to process truncated data to resolve the factors that affect the efficiency of the decision-making unit (DMU). By applying DEA and truncated regression analysis with bootstrapping, the performances of CPBL teams in games of different intensities were investigated. The number of foreign coaches and native players both were the key factors to affect the competitive efficiency of CPBL teams, and the Uni President 7-ELEVEN Lions had the best performance efficiency team. This interdisciplinary investigation provided the most appropriate references and recommendations for professional baseball teams on HR management so that baseball fans' expectations are met.
