The definitive property of a spin-fluctuation d-wave-pairing superconductor is that cuprate-plane Cu-site Ni is a weaker Cooper-pair-breaker than Zn on the same site. None of the major high-temperature superconductors, except possibly YBa 2 Cu 3 O x, exhibits this property experimentally.

The superconducting pairing instability — as determined by a divergence of the two-particle susceptibility — is obtained in the mean field (BCS) approximation in the thermodynamic limit. The usual practice is to examine this property for a finite lattice. We illustrate that, while the conclusions remain unchanged, the technical features are very different in the thermodynamic limit and conform more closely with the usual treatment of phase transitions encountered in, for example, the mean-field paramagnetic–ferromagnetic transition. Furthermore, by going to the extreme dilute limit, one can distinguish three dimensions from one and two dimensions, in which a pairing instability occurs even for two particles.

A large defective troilite (Fe0.9V0.1)0.82S is prepared by a sealed silica-tube method at 800oC and characterized by a powder X-ray diffraction method and using a magnetic property measurement system. The crystal structures of a defective troilite and non defective troilite are analyzed by Rietveld method. The large defect enhances the Fe-Fe pairing and suppresses the waving of Fe-chain along c-direction. The antiferromagnetic property is observed on both troilites. The spin-flip transition temperature of the large defective troilite is 9K.

With introduction of smart things into our lives, cloud computing is used in many different areas and changes the communication method. However, cloud computing should guarantee the complete security assurance in terms of privacy protection, confidentiality, and integrity. In this paper, a Homomorphic Encryption Scheme based on Elliptic Curve Cryptography (HES-ECC) is proposed for secure data transfer and storage. The scheme stores the data in the cloud after encrypting them. While calculations, such as addition or multiplication, are applied to encrypted data on cloud, these calculations are transmitted to the original data without any decryption process. Thus, the cloud server has only ability of accessing the encrypted data for performing the required computations and for fulfilling requested actions by the user. Hence, storage and transmission security of data are ensured. The proposed public key HES-ECC is designed using modified Weil-pairing for encryption and additional homomorphic property. HES-ECC also uses bilinear pairing for multiplicative homomorphic property. Security of encryption scheme and its homomorphic aspects are based on the hardness of Elliptic Curve Discrete Logarithm Problem (ECDLP), Weil Diffie-Hellman Problem (WDHP), and Bilinear Diffie-Helman Problem (BDHP).

The aim here is to show an example for localization and relevant low-dimensional superfluids in nuclear system. Due to a particular property of tensor force originating from the One-Pion-Exchange (OPE) between two nucleons, dense nuclear medium undergoes a layer confinement of the nucleons on one hand and also pion condensation (PC) for pion field mediating two-nucleon interaction on the other hand. The localization is characterized by a layered structure with a specific spin-isospin ordering. In that situation, the pairing problem has a two-dimensional (2D) character, i.e., low-dimensional superfluid realized in the hadronic matter with strong interactions. The pairing description suitable to the 2D nature is presented and possible realization of superfluidity in neutron stars is discussed, togeter with its effect on the cooling scenarios.

Multiservice cellular in Radio Access Network (RAN) Slicing has recently attained huge interest in enhancing isolation and flexibility. However, RAN slicing in heterogeneous networks (HetNet) architecture is not adequately explored. This study proposes a pairing-network slicing (NS) approach for Multiservice RAN that cares about quality of service (QoS), baseband resources, capacities of wireless fronthaul and backhaul links, and isolation. This intriguing approach helps address the increased need for mobile network traffic produced by a range of devices with various QoS requirements, including improved dependability, ultra-reliability low-latency communications (uRLLC), and enhanced broadband Mobile Services (eMBB). Our study displays a unique RAN slicing framework for user equipment (UE) for joint user-association. Multicell non-orthogonal multiple access (NOMA)-based resource allocation across 5G HetNet under successive interference cancelation (SIC) is seen to achieve the best performance. Joint user-slice pairing and association are optimization problems to maximize eMBB UE data rates while fulfilling uRLLC latency and reliability criteria. This is accomplished by guaranteeing the inter- and intra-isolation property of slicing to eliminate interferences between eMBB and uRLLC slices. We presented the UE-slice association (U-S. A) algorithm as a one-to-many matching game to create a stable connection between UE and one of the base stations (BSs). Next, we use the UE-slice pairing (U-S. P) algorithm to find stable uRLLC-eMBB pairs that coexist on the same spectrum. Numerical findings and performance analyses of the submitted association and pairing technique show they can all be RAN slicing criteria. We prove that the proposed algorithm optimizes system throughput while decreasing uRLLC latency by associating and pairing every uRLLC user in mini slots.

Texto completoResumen
Le problème du médian est un des problèmes les plus étudiés en théorie des espaces métriques. Nous l'étudions dans les graphes médians d'un point de vue algorithmique. Nous présentons un algorithme linéaire basé sur un calcul rapide des classes de parallélisme des arêtes (les Thêta-classes) via un parcours en largeur particulier (LexBFS). Nous donnons également un algorithme linéaire pour le problème du médian dans les l1-complexes cubiques des graphes médians et dans les structures d'évènements.Ensuite, nous présentons une caractérisation des graphes aux médians connexes dans la p-ième puissance Gp du graphe et donnons une méthode polynomiale pour vérifier si un graphe est un graphe aux médians Gp-connexes, étendant un résultat de Bandelt et Chepoi (cas p=1). Nous utilisons cette caractérisation pour montrer que certaines classes de graphes sont G2-connexes, comme les graphes de Helly bipartis et les graphes pontés. Nous travaillons également sur l'aspect axiomatique en étudiant l'ABC-problème, qui consiste à déterminer les graphes (nommés ABC-graphes) dans lesquels la fonction médian est l'unique fonction consensus respectant trois axiomes simples (A) Anonymat, (B) Intervalle (Betweeness) et (C) Cohérence. Nous montrons que les graphes modulaires aux médians G2-connexes sont des ABC-graphes et définissons de nouveaux axiomes pour caractériser la fonction médian dans d'autres classes de graphes, comme les graphes aux médians connexes. Nous prouvons également que les graphes respectant la propriété d'appariement (qui sont des ABC-graphes) est une sous-classe propre des graphes de Helly bipartis et étudions la complexité de la reconnaissance de ces graphesThe median problem is one of the most investigated problem in metric graph theory. We will start by studying this problem in median graphs. We present a linear time algorithm based on the majority rule which characterize the median in median graphs and on a fast computation of the parallelism classes of the edges (the \Theta-classes) via LexBFS which is a particular breadth first search algorithm.We also provide linear time algorithms to compute the median set in the l_1-cube complexes of median graphs and in event structures. Then, we provide a characterization of the graphs with connected medians in the pth power of the graph and provide a polynomial method to check if a graph is a G^p-connected median graph, extending a result of Bandelt and Chepoi (case p=1). We use this characterization to prove that some important graph classes in metric graph theory have G2-connected medians, such as bipartite Helly graphs and bridged graphs. We will also studied the axiomatic aspect of the median function by investigating the ABC-problem, which determine the graphs (named ABC-graphs) in which the median function is the only consensus function verifying three simples axioms (A) Anonymat, (B) Betweeness and (C) Consistency. We show that modular graphs with G2-connected medians are ABC-graphs and define new axioms allowing us to characterize the median function on some graph classes. For example the graphs with connected medians (including Helly graphs). We also show that a known class of ABC-graphs (graphs satisfying the pairing property) is a proper subclass of bipartite Helly graphs and we investigate their recognition

Texto completoResumen
The Moral Project of Childhood argues and demonstrates that fundamental problems stemming from a growing acceptance of children’s moral, spiritual, intellectual, and behavioral pliability drive the assembly of a contemporary “moral architecture” of childhood from extensive maternal responsibility coupled with the increasingly hegemonic presence and existence of child subjecthood. Drawing on materials published in periodicals intended for women and mothers from the 1830s to the 1930s, the book examines how mothers—and, later, commercial actors—found themselves compelled to consider children’s interiorities: their perspectives, needs, wants, pleasures, and pains. In this process, the child’s subjectivity progressively, albeit unevenly, arises as a form of authority in a variety of contexts, including discourses about Christian motherhood, the elements of cultural taste, and the discipline and punishment of children, as well as in machinations about play and toys, questions of children’s property rights, and the uses of money by and for children. The book considers the Protestant origins of the child consumer—a somewhat unlikely pairing—and makes visible and relevant the prefigurative elements and rhetorics from which the child consumer emerges as a contemporary, dominant, and normative ideal.

The current landscape of virtue epistemology is ripe with possibilities for theological engagement and appropriation. Constructively speaking, Maximus the Confessor (580–662 ce) is a fitting example of this kind of intersection. In terms of mapping the cognitive economy of the spiritual life, he draws attention to virtuous and contemplative practices that enable the intellect to attain its proper end (divine likeness) and acquire the related epistemic goods. Accordingly, this chapter shows how the virtues, for Maximus, contribute to the formation of a deep and abiding desire for the relevant epistemic goods (e.g. contemplation of God in and through nature, illumination of divine truths, wisdom, and perceptual knowledge of God) as well as playing a supportive role in the pursuit of them. It also offers briefly some concluding reflections concerning Maximus’s pairing of virtue and knowledge, and identifies a few areas of enquiry that warrant further work and development.

Texto completoResumen
This paper contrasts the dative/accusative alternations in Romance languages with Romanian: In Romance, this alternation mediates the emergence of a DOM particle for direct objects, in addition to the preservation of the same particle with the indirect object (morphological extension). The case assigning property of this particle is paramount in both contexts. On the other hand, in Romanian, the dative/accusative alternation ends up with the complete substitution of one syntactic pattern by the other in the same position; e.g., dative inflected direct objects of Old Romanian (theme/patient theta-role) are substituted by accusatives with or without DOM in Modern Romanian. The change concerns the general option for analytical versus synthetic case in the grammar, irrespective of DOM. This contrast confirms the conclusions of previous studies that the development of DOM in Romanian involves different morpho-syntactic patterns than those proposed for Romance languages (e.g., Spanish), especially with respect to the origin and function of the DOM particle and the pairing of case marking on DP and the theta-roles they spell out.

This paper presents a new homomorphic public-key encryption scheme based on the elliptic curve cryptography (HPKE-ECC). This HPKE-ECC scheme allows public computation on encrypted data stored on a cloud in such a manner that the output of this computation gives a valid encryption of some operations (addition/multiplication) on original data. The cloud system (server) has only access to the encrypted files of an authenticated end-user stored in it and can only do computation on these stored files according to the request of an end-user (client). The implementation of proposed HPKE-ECC protocol uses the properties of elliptic curve operations as well as bilinear pairing property on groups and the implementation is done by Weil and Tate pairing. The security of proposed encryption technique depends on the hardness of ECDLP and BDHP.

This chapter analyzes how the Socialist Party of America invoked the “Second American Revolution” to advocate left nationalism, incremental reform, and Christian socialism, or to validate calls for revolution or international industrial emancipation. Pairing the class struggle with abolitionism tied socialism to domestic tradition and rendered the Civil War part of a revolutionary struggle. The Industrial Workers of the World, meanwhile, claimed one of the most contentious legacies of the abolitionists: the defiance of absolute property rights. However, the Red Scare helped undermine the socialist narrative of the war for the Union as a working-class war. Political repression reinforced the decline of revolutionary Civil War memories, which in turn yielded before rising strains of conservative industrial patriotism.

This chapter argues that private property in fact is necessary to realizing relational equality. It asserts that one requires property rights to satisfy the moral requirement that we relate to one another on terms of equality. The chapter shows that the obligations of property, and the concomitant wrongs made possible by those obligations, are what makes property good from an egalitarian perspective. Many of the valuable social roles that people occupy are structured and indeed constituted by the law of private property (e.g., roles of homeowner, host, and gift-giver). These roles, moreover, are accompanied by valuable counterpart roles (those of neighbor, guest, and gift-recipient). This chapter thus argues that the relations that obtain between these pairings are egalitarian insofar as the parties to them relate on equal terms, and it maintains that it is the law of private property that makes such relations possible.

Texto completoResumen
Even if we take a ‘replicators first’ view of the origin of life, we still have to explain how a chemical environment arose that was sufficiently diverse for such replicators to be formed. As a minimum, we must explain the abiotic formation of sugars and amino acids, and of nucleotides or of some simpler molecules capable of base pairing, and hence of template reproduction. Lipids would not be needed for the first appearance of replicating molecules, but were crucial if evolution was to proceed further. Their importance is apparent from the chemoton model: by forming membranes, they make possible the formation of protocells, and hence of a unit of selection more complex than a replicating molecule. In turn, this encourages the evolution of cooperation between replicators, as discussed in the next chapter. This chapter describes how such a diverse chemical environment could arise. In section 3.2, we introduce the familiar idea of a ‘primitive soup’, and review the experimental evidence concerning what compounds can, and cannot, be formed. Although a surprising array of organic compounds have been synthesized in such experiments, there are some awkward gaps. Section 3.3 describes the more recent, and more promising, idea that the crucial chemical events took place between compounds bonded to a charged surface. There are several reasons why the idea is attractive. Chemical reactions will be both more frequent and more specific if the reacting molecules are moving on a surface, rather than in three dimensions. Also, some reactions will be energetically favoured. In particular, the formation of biological polymers (proteins, nucleic acids) requires the removal of a molecule of water: this is difficult for molecules in solution in water, but easier on a surface. The chemoton model incorporates an autocatalytic cycle, producing two molecules of a compound where one existed before. Such cycles are discussed in section 3.4. They are an essential feature of metabolism. It is important, however, to remember that autocatalytic cycles are not replicators: this distinction is made clearer in Chapter 4. Section 3.5 discusses whether chemical ‘evolution’, in the primitive soup or on a surface, is really evolution. In our view, evolution requires heritable variation: this property is lacking from the reactions discussed in this chapter.

Texto completoResumen
Very popular research in the field of Modern control Engineering is design of controllers for nonlinear systems. It is obvious that all the real-world systems are multivariable and nonlinear in nature which is highly challenging to control these nonlinear systems as it exhibits complexity. In addition to these, all the real systems exhibit uncertainty due to slow or sudden changes in process parameters. Hence, the design of robust nonlinear controller should have an ability to handle these uncertainties. The design of controllers for nonlinear system needs proper selection of appropriate input–output pairing. This book chapter focus on the conventional and proposed method of control configuration selection for nonlinear systems.

This chapter examines the inversion of the gender order in the Henry VI plays. The plays show a good deal of this disorder stemming from women either aspiring to get or else successfully climbing ‘on top’. This process can be seen quite clearly—in the first half of part II—in the pairing of the duchess of Gloucester with Queen Margaret, and throughout both plays in the progression of Queen Margaret from ambitious and unfaithful wife and subject to faction leader, warrior and ruler, until finally she becomes the virtual personification of violent revenge pursued for its own sake. From the outset, the play portrays both duchess and queen as disobedient, proud, and ambitious women, aspiring to a degree of power and influence first over their husbands, and then over the wider political system, far greater than anything a properly obedient and ordered woman and wife ought to aspire to.

Texto completoResumen
This chapter traces the history of the Christological language of the miracles and sufferings of Christ from the fourth through sixth centuries. Armenian, Coptic, Latin, Greek, and Syriac texts pair the miracles of Christ with the sufferings of Christ to express the relationship between his divinity and humanity. This pairing first appeared in Cappadocia in the late fourth century, but it became a source of controversy especially through Cyril of Alexandria and Nestorios of Constantinople’s disagreement. The presence of this phrase in Pope Leo I’s Tome led to further disagreements at the Council of Chalcedon in 451. The Emperor Zeno used this phrase in an imperial decree issued in 482, known as the Henotikon, and it would later be codified in Roman law through the Emperor Justinian I. Miaphysite leaders, including Jacob of Serugh, debated the proper understanding of Christology in reference to this phrase in the early sixth century.

Key negotiation can establish a shared key between two or even multiple parties in a public networkenvironment, ensuring communication confidentiality and integrity. Certificateless public key cryptography(CL-PKC) aims to achieve succinct public key management without using certificates, while avoiding thekey escrow property in identity-based cryptography. As an important part of CL-PKC, certificateless authentication key agreement (CLAKA) has also received widespread attention. Most CLAKA protocols are constructed from bilinear mappings on elliptic curves which need costly operations. To improve theperformance, some pairing-free CLAKA protocols have been proposed. In this paper, we propose a multifactor authentication CLAKA protocol that can achieve local authentication factors joint unlocking. Theprotocol does not require bilinear pairing computation and has been proven to be secure under the mBRmodel.

Texto completoResumen
Digital Linguistics (DL) is an interdisciplinary study that identifies human language as a digital evolution of mammal analog vocal sign communications, founded on the vertebrate spinal sign reflex mechanism [Tokumaru 2017 a/b, 2018 a/b/c/d]. Analog signs are unique with their physical sound waveforms but limited in number, whilst human digital word signs are infinite by permutation of their logical property, phonemes. The first digital evolution took place 66,000 years ago with South African Neolithic industries, Howiesons Poort, when linguistic humans acquired a hypertrophied mandibular bone to house a descended larynx for vowel accented syllables containing logical properties of phonemes and morae. Morae made each syllable distinctive in the time axis and enabled grammatical modulation by alternately transmitting conceptual and grammatical syllables. The sign reflex mechanism is an unconscious self-protection and life-support mechanism, operated by immune cell networks inside the ventricle system. DL identified cellular and molecular structures for the sign (=concept) device as a B lymphocyte (or, in other words, Mobile Ad-Hoc Networking Neuron), connects to sensory, conceptual and networking memories, which consist of its meanings [Table 1]. Its antibodies can network with antigens of CSF-Contacting Neurons at the brainstem reticular formation and of Microglia cells at the neocortex [Figure 1]. It is plausible that the 3D structure of the antigen molecule takes the shape of word sound waveform multiplexing intensity and pitch, and that specifically pairing the antibody molecule consists of three CDRs (Complementality Defining Regions) in the Antibody Variable Region network with the logic of dichotomy and dualism. As sign reflex deals with survival issues such as food, safety and reproduction, it is stubborn, passive and inflexible: It does not spontaneously look for something new, and it is not designed to revise itself. These characteristics are not desirable for the development of human intelligence, and thus are to be overcome. All the word, sensory and network memories in the brain must be acquired postnatally through individual learning and thought. The reason and intelligence of humans depend on how correctly and efficiently humans learn new words and acquire appropriate meanings for them.

Texto completoResumen
El presente trabajo de investigación se centra en conformar el factor de localización, entendido como un parámetro integrador, en función de sus características particulares de ubicación, atributos constructivos y condiciones socioeconómicas de carácter local. Para ello se hace necesario medir los atributos endógenos-exógenos de mayor incidencia sobre el precio de los inmuebles, los cuales vienen a ser los elementos que dan forma a la distribución del mercado residencial de la ciudad.
El trabajo se baso en un estudio econométrico del mercado residencial en la ciudad de Mazatlán, Sinaloa, para lo cual se requirió el uso de las metodologías de los preciso hedónicos, regresión lineal múltiple y geográficamente ponderada.
Los resultados ratifican que la conformación del valor de la vivienda depende del binomio de elementos extrínsecos-intrínsecos de los inmuebles, cuya incidencia varia en el territorio, conformando zonas de valor, cuyo peso marginal puede ser interpretado con el factor de de localización encontrado, el cual representa una medida diferencial entre las distintas zonas de la ciudad. Este parámetro se puede utilizar en el cálculo del factor de homogenización por localización en el método de valoración por comparación de mercado. This research work focuses on shaping the location factor, seen as an integrative parameter, depending on their specific location, building attributes and local socioeconomic conditions. This is necessary to measure the endogenous-exogenous attributes most directly affect the price of the property, which come to be the elements that shape the distribution of city's residential market.
The work was based on an econometric study of the residential market in the city of Mazatlan, Sinaloa, which is required for the use of hedonic precise methodologies, linear regression and geographically weighted.
The results confirm that the conformation of the value of the home depends on the pairing of extrinsic-intrinsic elements of the buildings, whose incidence varies in the territory, forming areas of value, marginal weight of which can be used with the factor of location found, this represents a differentials measurement between diverse areas of the city. This parameter can be used in calculating the factor of homogenization of by location in the method of valuation by the market comparison.

Thermal striping is of particular significance in nuclear reactor applications, primarily in sodium cooled fast reactors. The mixing chamber of the upper plenum of a nuclear reactor can be subjected to thermal striping unless designed such that the coolant is sufficiently mixed prior to reaching the top wall of the upper plenum. In order to conduct a systematic analysis of this phenomenon a simplified experimental set-up was designed and built at Argonne National Laboratory. In a parallel effort a similar simulation was conducted using the spectral-element code Nek5000. The set-up consists of two turbulent jets entering a rectangular tank via two hexagonal inlets, the interesting phenomena being the mixing within the tank. Two different inlet geometries were studied previously, both experimentally and via high-fidelity large-eddy simulations reporting various turbulent statistical quantities. To further assess the flow behavior we hereby perform a Proper Orthogonal Decomposition (POD) to identify the most dominant energetic modes and quantify their impact on the top wall of the upper plenum. The POD analysis of the experimental data in both inlet geometrical configurations is compared with LES and presented to highlight the impact of geometry on the velocity and thermal fields. We find a qualitative coherence between both simulation and experiment, characterized by a strong backflow in the weakly stable geometry, as indicated by the first mode, and the presence of three stagnation points in the strongly stable geometry setup. Also we identify a pairing of modes 1 and 3 with higher frequency than the second mode. This pairing is opposite in the two flow configurations leading to a faster decay of one of the jets in one case and a stable flow in the other.

Abstract Production analytical approaches specially in presence of smart well completion equipped with several PDGs, if applied appropriately, can overcome many challenges in study of complex reservoirs with comingled production that numerical modelling alone is not capable of. The objective of this work was to firstly utilize automation and programming to compile the massive amount of PDG data in smart completion and offer a workflow to overcome the missing data and challenges for analysis. Secondly this work customs a blend of different analytical approaches such as PTA, RTA, Material Balance combined with Teager-Keiser Energy Method to understand the many unknowns and uncertainties of water injection effectiveness in one of the heavily faulted multi-stack reservoirs in East Malaysia. For a proper reservoir characterization, knowing of accurate rate is a must, yet an accurate allocation itself is a function of formation properties, mainly permeability and skin. With the help of scripting, data from PDG is compiled. Preprocessing has been done to identify the fluid type produced from each layer. A workflow has been introduced to tackle the back allocation issue with FCV variation while allowing the luxury of full dynamic characterization of multi-stack reservoirs producing from single string. While every analytical approach has its own limitations and strengths, this work showcased how to apply different methods depends on the situation to squeeze the maximum information whether is to understand the injector-benefiter pairing, fault sealing and compartmentalization, connected volume, or fine migration and loss of injectivity. Processing of PDG big data made it possible for a dynamic interpretation of whole production period rather than selective time span. This work made us able to answer some of the last longing question such as the cause for injectivity deterioration, proper reservoir characterization aligned with geological understanding, and proper allocation suggested by new workflow. PTA results have been validated along other analytical methods such as RTA and material balance to understand connected volume, fault transmissibility and infill well potential. Teager-Keiser showed extremely helpful when combined with previous methods to recognize benefiter-injector pairing before any lagging evidence such as GOR and pressure trend, water production and salinity test can confirm the connectivity. Apart from the workflow to interpret the PDG of smart well completion producing commingled from multi-stack reservoirs, the work has been benefited from digitalization using open-source programming. The idea of dynamic data interpretation, how to deal with missing production data to enhance the accuracy of PTA analysis, and cross-validation through different approaches to shed light on the unknown of reservoir complexities to revisit and optimize water injection scheme, are the other highlights of this study.

A nonlinear computational aeroelasticity model based on the Euler equations of compressible flows and the linear elastodynamic equations for structures is developed. The Euler equations are solved on dynamic meshes using the ALE kinematic description. Thus, the mesh constitutes another field governed by pseudo-elatodynamic equations. The three fields are discretized using proper finite element formulations which satisfy the geometric conservation law. A matcher module is incorporated for the purpose of pairing the grids on the fluid-structure interface and for transferring the loads and displacements between the fluid and structure solvers. Two solutions strategies (Gauss Seidel and Schur-Complement) for solving the nonlinear aeroelastic system are discussed. Using second order time discretization schemes allows us to use large time steps in the computations. The numerical results on the AGARD 445.6 aeroelastic wing compare well with the experimental ones and show that the Schur-complement coupling algorithm is more robust than the Gauss-Seidel algorithm for relatively large oscillation amplitudes.

Abstract Prediction of human movement, and especially of pathological gait, is nowadays an important and mostly unsolved research challenge. In this work, a recently developed computational framework based on optimal control was adopted and explored to assess its potential for predicting a pathological gait pattern, in particular the crouch gait typical of subjects affected by cerebral palsy. To this end, the generic musculoskeletal model on which this optimal control framework is based was made representative of such pathological case by modeling contracture of relevant muscle groups commonly associated with crouch gait, namely knee and hip flexors. All the conducted simulations succeeded in inducing the model into a crouch gait pattern, despite their diversity in cost functions. Moreover, the obtained joint angle trajectories correlated well with the experimental ones obtained from a CP child walking in crouch. These kinematic results suggest that optimal control techniques and proper tuning of musculotendon parameters are an important pairing for predictive simulations of human walking. On the other hand, the obtained results confirm that estimation of muscle activations is strongly dependent on the selected objective function and still requires deeper investigations.

Abstract As processors continually seek greater computational output, the traditional single die processor configuration is giving way to emerging multi-die processor assemblies. As a result, dies of varying powers are spatially distributed in processor packages, causing local areas of high heat density and non-uniform temperature patterns. If not properly addressed, local hot spots may limit the total device operating power, increase leakage current to lower processor efficiency, and accelerate thermal induced semiconductor deterioration to reduce device lifetime. In this article, a modular microconvective heat sink (M2HS) is developed as a high effectiveness, high flexibility cooling solution for multi-die assemblies. Microconvective cooling, featuring optimized single-phase impingement cooling and effluent fluid flow control, provides high power density heat removal from localized heat flux zones on semiconductor dies. An AMD Threadripper 3960X is chosen as a multi-die test vehicle for the M2HS to test thermal performance in a liquid cooled experimental flow loop. Experimental results in overclocked thermal stress tests are presented, achieving power draws of up to 75% higher than the nominal processor TDP. Further, compared to a recommended product pairing of the CPU serving as a baseline heat sink, the M2HS showed a 51% improvement in CPU power draw performance. When operating at nominal, non-overclocked conditions, reduced temperature operation of the CPU using M2HS solutions resulted in a CPU efficiency increase of up to 10% compared to the baseline heat sink, providing opportunities for reduced PUE in large scale data centers. The study concludes that the M2HS shows promise as a high effectiveness, implementation-friendly cooling solution for emerging multi-die processor assemblies.

Texto completoResumen
In human-machine cooperation, machines may assist operators in a variety of ways. This paper discusses the coordination of various assistances on cognitive basis through a PID-based control approach. Cognitive assistance can be viewed as a two-dimensional problem. The question of when to provide assistance can be viewed as a control problem, and the question of what assistance to provide can be viewed as an interface problem. This research proposes pairing cognitive engagement level and performance relevant situation criticality with a PID control approach to determine the appropriate moment to provide proper assistance. Based on the stage of human cognitive processing, the interfaces of cognitive assistance are grouped into three levels: soft aid, soft intervention, and hard intervention. This paper took driving assistance as an exemplary application to validate the approach of cognitive assistances coordination. In the experiment, an intelligent machine driver monitored drivers’ real-time performance by measuring the time headway to front obstacles and the lateral deviation to lane center. Simultaneously, it monitored drivers’ cognitive state by measuring the eye movement with an eye tracker. With five sessions of driving, coordinated cognitive assistance was compared with no aid, soft aid, soft intervention, and hard intervention, respectively. The experimental results confirmed that coordinated cognitive assistance is the most effective approach to assist both primary and secondary tasks. It also proves to be a more enjoyable and less obtrusive assistance system when compared to other individual types of assistance. In addition, coordinated cognitive assistance can be extended to other real-time control relevant tasks.
