Bandwidth Limits in Hall Effect-based Current Sensors (2017)

&lt;p class="Abstract"&gt;&lt;span lang="EN-GB"&gt;Modern power applications are demanding for small and broadband current sensors. Hall sensors are a good solution, but practical implementations are limited to a few hundred kHz. The literature offers a theoretical knowledge about the dynamic effects acting on the Hall probe but does neither define nor experimentally assess the bandwidth fundamental upper limit, since many parasitic dynamic effects perturb the inherent time response of the Hall sensor. This paper experimentally investigates the bandwidth upper limits in CMOS Hall effect-based current sensors. Based on the physics-based description of the Hall probe, the paper defines a novel, special-purpose, measurement technique, which is able to experimentally evaluate the inherent response time of the Hall probe without triggering the main parasitic effects. The paper also propose an equivalent electrical model describing the dynamic response of the Hall probe so as to better explain and understood the measurement results. Specifically, the paper identifies two bandwidth upper limits: a fundamental limit set by the intrinsic capacitance, which models the transversal charge accumulation due to the Hall effect, and a more practical limit set by the capacitive input of the electronic readout interface. Some main parasitic effects are then assess and added in the proposed model.&lt;/span&gt;&lt;/p&gt;

Physically Disentangled Representations (2022)

State-of-the-art methods in generative representation learning yield semantic disentanglement, but typically do not consider physical scene parameters, such as geometry, albedo, lighting, or camera. We posit that inverse rendering, a way to reverse the rendering process to recover scene parameters from an image, can also be used to learn physically disentangled representations of scenes without supervision. In this paper, we show the utility of inverse rendering in learning representations that yield improved accuracy on downstream clustering, linear classification, and segmentation tasks with the help of our novel Leave-One-Out, Cycle Contrastive loss (LOOCC), which improves disentanglement of scene parameters and robustness to out-of-distribution lighting and viewpoints. We perform a comparison of our method with other generative representation learning methods across a variety of downstream tasks, including face attribute classification, emotion recognition, identification, face segmentation, and car classification. Our physically disentangled representations yield higher accuracy than semantically disentangled alternatives across all tasks and by as much as 18%. We hope that this work will motivate future research in applying advances in inverse rendering and 3D understanding to representation learning.
Dating Methods of Pleistocene Deposits and Their Problems: The Promise of Atom Counting (1979)

Recent developments in mass spectrometry, using some of the apparatus and techniques of nuclear physics, have made possible the detection of the cosmic ray created 14 C, 10 Be and 36 C1 nuclei at natural concentrations by atom counting. The small sample size, a few milligrams, promises to revolutionize 14 C dating and to introduce new dating methods for the Pleistocene.
The 68040 on-chip memory subsystem (2002)

The Motorola 68040 is a third-generation, high-performance, full 32-b microprocessor. The caches, memory-management units (MMUs), and autonomous controllers for the caches and external bus that comprise the memory subsystem are described. The 68040's memory subsystem supports the performance of the integer and floating-point units by using autonomous internal cache/MMU controllers in a Harvard architecture. Physical caches of 4 kB each for instruction and data are provided. The data cache operates in copyback or write-through mode on a per-page basis. Combined with each cache is a separate address translation cache of 64 entries and two transparent translation registers that operate in parallel with the cache to provide complete memory management in a virtual, demand-page environment. The memory subsystem is designed to provide the majority of the required memory bandwidth for the internal caches. The 68040 has two MMUs: one for instruction logical-to-physical address translation and one for data address translation. High performance is possible owing in part to the high level of concurrency available in the memory subsystem.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Problems related to blocked nailing in fractures of the proximal femur. (1989)

The modern treatment of fractures of the proximal femur in the adult usually involves surgery. Open plating has proved to be reliable, but often involves a high percentage of complications: axial deformity, delayed union, breakage of the plate and/or screws (the risk of which increases in relation to the degree of comminution). At this site, in fact, the plate is submitted to strong flexion stress. It therefore becomes essential to associate cancellous grafts (as proposed by the AO School) (Muller et al., 1981) or a homoplastic cortical craft (as in our experience) (Zinghi and Masetti, 1982). Furthermore, open osteosynthesis is time consuming and this means considerable blood loss and a risk of infection. There are thus many reasons for preferring closed surgery, but effective stabilisation can only be obtained with blocked nailing; in fact, only metadiaphyseal screwing is capable of neutralising the rotation or axial stresses which cause deviation, instability or telescoping of the fracture (Kempf et al., 1978; Tigani et al., 1986; Zinghi et al., 1984). Osteosynthesis with Grosse-Kempf nailing is thus an effective alternative to open nailing, particularly in those fractures which would require additional bone grafting with this method. The purpose of our study was to verify the effectiveness of intramedullary osteosynthesis with Grosse-Kempf blocked nailing, in particular analysing the problems encountered in the use of this method.
User Experience Research in the Work Context: Maps, Gaps and Agenda (2022)

User experience (UX) research has been criticized for focusing on leisure contexts and overlooking the work contexts. Moreover, researchers have been drawing attention to how UX at work differs from UX in leisure contexts, requiring development of domain specific knowledge. Inspired by these discussions, our motivation is to see the current state of UX at work research. Based on the systematic review of 52 papers, our results revealed that UX at work research is still immature. It is run by dichotomies; the conceptualizations such as the definition and the dimensions of UX at work are ambiguous; the variety of the studied work domains are limited and do not contribute to the understanding of UX at work; and the consideration of contextual factors are arbitrary and coincidental. To advance this important field of research, we indicate the research gaps and suggest a research agenda introducing areas for future research.
Dynamic anti-windup method for a class of time-delay control systems with input saturation (2000)

An anti-windup-based approach is newly attempted to deal with time-delay control systems with input saturation. Following the anti-windup paradigm, we assume that controllers have been designed beforehand for time-delay control systems based on existing design techniques which will show desirable performance. Then, an additional compensator is designed to provide graceful performance degradation under control input saturation. By taking the difference of controller states in the absence and presence of input saturation as a performance index, a dynamic compensator which minimizes it is derived. The resulting anti-windup compensator is expressed in plant and controller parameters. The proposed method not only provides graceful performance degradation, but also guarantees the stability of the overall systems. Illustrative examples are provided to show the effectiveness of the proposed method. Copyright © 2000 John Wiley & Sons, Ltd.
Cobalt(III) and gallium(III) complexes of meso-free corroles with distinct position-dependent substituent effects (2016)

Co(III) and Ga(III) complexes of 5,10-bis(pentafluorophenyl)corrole and 5,15-bis(pentafluorophenyl)corrole were synthesized by metalations with Co(OAc) 2 •4H 2 O and GaCl 3 , respectively. The structures of these complexes have been all unambiguously revealed by X-ray diffraction analysis. Their optical and electrochemical properties have been studied, which reveals small but distinctly different substituent effects depending upon the substitution positions.
Introduction (2015)

‘Keep close your friend's letters, for craft and malice never reigned more’. This is the warning that one friend gave to another in 1587, but it would have been good advice at any time in the sixteenth century. Those who sent letters on personal or political business under the Tudors had every reason to fear the ‘craft and malice’ of spies, and some resorted to ciphers and secret tokens. One such was Edward Courtenay, First Earl of Devon. In the winter of 1553–4, when he was widely believed to be the best match for Princess Elizabeth, Courtenay found himself ‘the rallying point for every major conspiracy’ against her half-sister, Queen Mary. To communicate with his allies, Courtenay hit upon a device that was unusually ingenious even by the standards of Elizabethan duplicity. He took a guiterre and marked it with a cipher known to his principal associate, Peter Carew. The deceit was soon discovered, however, and became common knowledge at court. The news reached two imperial ambassadors who reported it to their master, Charles V, a ruler with a deep political interest in the fortunes of the restored Catholic monarchy in England. The ambassadors assured the Emperor that Queen Mary and her Privy Council, having interrogated various suspects, now believed
A service oriented approach to continuous media synchronization (2002)

The development of ATM networking makes it attractive to use computer communication networks for the transport of digital audio and motion video. When coupled with advances in workstation technology, this creates the opportunity to integrate these continuous information media within a distributed computing system. Continuous media have an inherent temporal dimension, resulting in a set of synchronization requirements which have real-time properties. The paper identifies the role and position of synchronization, in terms of the support which is necessary in an integrated distributed system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Amino acid sequences of ferredoxins from Alocasia macrorrhiza Schott in Papua New Guinea. (1992)

The amino acid sequences of ferredoxin isoproteins (Fd A and Fd B) from Alocasia macrorrhiza Schott in Papua New Guinea were determined. They consisted of single polypeptide chains of 97 and 98 residues, respectively, and both Fds had a molecular mass of 10,800 Da. There was an 88% identity between the sequences of the isoproteins (Fd A and Fd B). These sequences were compared with those of the closely related plant Fds and their phylogenetic relationships are discussed.
Chronic Lithium Chloride Administration to Unanesthetized Rats Attenuates Brain Dopamine D2-Like Receptor-Initiated Signaling Via Arachidonic Acid (2005)

We studied the effect of lithium chloride on dopaminergic neurotransmission via D2-like receptors coupled to phospholipase A2 (PLA2). In unanesthetized rats injected i.v. with radiolabeled arachidonic acid (AA, 20:4 n-6), regional PLA2 activation was imaged by measuring regional incorporation coefficients k* of AA (brain radioactivity divided by integrated plasma radioactivity) using quantitative autoradiography, following administration of the D2-like receptor agonist, quinpirole. In rats fed a control diet, quinpirole at 1 mg/kg i.v. increased k* for AA significantly in 17 regions with high densities of D2-like receptors, of 61 regions examined. Increases in k* were found in the prefrontal cortex, frontal cortex, accumbens nucleus, caudate-putamen, substantia nigra, and ventral tegmental area. Quinpirole, 0.25 mg/kg i.v. enhanced k* significantly only in the caudate-putamen. In rats fed LiCl for 6 weeks to produce a therapeutically relevant brain lithium concentration, neither 0.25 mg/kg nor 1 mg/kg quinpirole increased k* significantly in any region. Orofacial movements following quinpirole were modified but not abolished by LiCl feeding. The results suggest that downregulation by lithium of D2-like receptor signaling involving PLA2 and AA may contribute to lithium's therapeutic efficacy in bipolar disorder.
Separating chemistry and transport effects in two‐dimensional models (2004)

Representation of transport in numerical models is known to be a major uncertainty in modeling of the atmosphere. Models also differ in their treatment of gas phase and heterogeneous chemistry. This paper will describe a quantitative approach to diagnosing the source of intermodel differences in ozone assessment calculations. Our approach is applied to diagnosing the differences between two‐dimensional (2‐D) models from Atmospheric and Environmental Research, the NASA Goddard Space Flight Center, and the Lawrence Livermore National Laboratory. Surprisingly, we find that differences due to chemical formulation are often as large as those due to transport, despite the fact that all models use the same set of reaction rate coefficients. These differences are particularly large when polar stratospheric cloud (PSC) processes are included in the models, though differences due to photolysis rates and details of the sulfate chemistry are also apparent. Perturbation calculations for a scenario including supersonic commercial aircraft operating in the 2015 stratosphere reveal that differences in the accumulation of H 2 O and NO y emitted by aircraft are due almost entirely to transport, while differences in ozone due to chemical formulation are evident in the lower stratosphere even without differences in H 2 O and NO y and without PSCs. By demonstrating a capability of separating transport and chemical differences, it is hoped that the results described in this paper will stimulate analogous studies with other models and will thus lead to a deeper understanding of intermodel similarities and differences, along with a means to quantify uncertainties in model predictions of atmospheric response to perturbations.
Design of steel-strapped, high-strength concrete columns subject to unequal end moments (2017)

A new equation is proposed for practical flexural design of high-strength concrete columns confined externally with tensioned steel straps. The proposed equation is based on the simplified approach of the equivalent moment factor adopted by existing design codes. It also accounts for non-linear behaviour of the materials, which is usually neglected in the codes. The equation was derived using results from rigorous theoretical analyses of 120 simulated strap-confined columns subjected to short-term ultimate loads and unequal flexural moments at the column ends. The theoretical simulations accounted for parameters shown to influence the design of strap-confined columns, such as load eccentricity, longitudinal reinforcement ratio, free concrete cover and volumetric confinement ratio. The proposed equation was found to predict the strength of strap-confined columns with sufficient accuracy, making it suitable for practical design and rapid assessment of such structures.
Vertical interaction in open software engineering communities (2009)

Software engineering is still a relatively young field, struggling to develop consistent standards and methods across the domain. For a given project, developers can choose from dozens of models, tools, platforms, and languages for specification, design, implementation, and testing. The globalization of software engineering and the rise of Open Source further complicate the issues as firms now must collaborate and coordinate with other firms and individuals possessing a myriad of goals, norms, values, expertise, and preferences. This thesis uses four empirical studies to take a vertical examination of Open Source ecosystems and identify the way that foundations, firms, and individuals come together to create large scale software ecosystems and produce world class software despite their differing goals and values. 
First, I examine Open Source as a collaborative phenomenon between firms and non-profit foundations that support many communities and identify the ways in which non-profit foundations enable member firms to create value in the ecosystem. Next, an empirical study of direct collaboration between firms within the Eclipse system reveals that most firms operate relatively independently, but there is still heavy reliance on a single dominant player for core portions of the ecosystem. I then evaluate how the presence of commercial firms affects the attraction and retention of volunteer developers in an Open Source community. The final study examines how individual developers manage their dependencies in Open Source and extends the socio-technical congruence metric to address changing requirements and facilitate the metric as a tool for continual use. Finally, based on the findings of these studies, I close with a set of recommendations for stakeholders investing in Open Source.

A Fast Algorithm for Adapted Time–Frequency Tilings (1996)

We first consider orthonormal bases of open face RNconsisting of discretized rescaled Walsh functions, whereNis a power of two. Given a vector, the best basis with respect to an additive cost function is found with an algorithm of orderO(NlogN). The algorithm operates in the time–frequency plane by constructing a tiling of minimal cost among all possible tilings with dyadic rectangles of area one. Then we discuss generalizations replacing the Walsh group, which controls the structure of the time–frequency plane, by other finite abelian groups. The main example here involves the Fast Fourier Transform.
Polarity driven formation of InAs/GaAs hierarchical nanowire heterostructures (2008)

The structural and morphological characteristics of InAs/GaAs radial nanowire heterostructures were investigated using transmission electron microscopy. It has been found that the radial growth of InAs was preferentially initiated on the {112}A sidewalls of GaAs nanowires. This preferential deposition leads to extraordinarily asymmetric InAs/GaAs radial nanowire heterostructures. Such formation of radial nanowire heterostructures provides an opportunity to engineer hierarchical nanostructures, which further widens the potential applications of semiconductor nanostructures.
The relationship between anemia, fecal stercobilinogen, erythrocyte survival, and globin synthesis in heterozygotes for beta-thalassemia (1975)

Erythrocyte survival, fecal stercobilinogen, and the alpha/beta-chain synthesis ratio in recticulocytes and bone marrow (six cases only) were determined and related to the hemoglobin levels in ten heterozygous carriers of beta-thalassemia with different degrees of anemia. Erythrocyte survival values were low, though not related to the degree of anemia, whereas stercobilinogen values and changes in the peripheral blood alpha/beta-chain ratios were so correlated. In the case of bone marrow, on the other hand, the ratio between alpha-chain and beta-chain synthesis was virtually 1, irrespective of the degree of anemia. It is suggested that the severity of anemia in heterozygous carriers is independent of peripheral hemolysis and entirely attributable to destruction of erythroblasts within the marrow.
CACSD benchmark problem no.3 (1989)

The Computer-Aided Control Systems Design (CACSD) Technical Committee of the IEEE Control Systems Society has proposed a third benchmark problem for the control community. This benchmark problem is described. It relates to two linear multirate sampled-data models that were first described by P.A. Hawley and T.R. Stevens (Proc. 3rd IEEE Symp. Comput.-Aided Control Syst. Design, Sept. 1986). The problem requires the evaluation of time responses, equivalent single-rate mathematical models, eigenvalues, open- and closed-loop frequency responses, and transfer-function poles and zeros.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Effect of Cinacalcet Hydrochloride, a New Calcimimetic Agent, on the Pharmacokinetics of Dextromethorphan: In Vitro and Clinical Studies (2007)

Cinacalcet hydrochloride (cinacalcet) is a positive allosteric modulator of the calcium-sensing receptor indicated for the treatment of secondary hyperparathyroidism in dialysis patients. In vitro study has demonstrated that cinacalcet is a potent inhibitor of cytochrome P450 (CYP) 2D6 with a K(i) value of 0.087 micromol/L, which is comparable to the well-known potent CYP2D6 inhibitor, quinidine (0.064 micromol/L). A clinical study was conducted to assess the inhibitory effect of cinacalcet on CYP2D6 substrates in healthy volunteers. Each subject received 50 mg of cinacalcet or a matched placebo orally once daily for 8 days with 30 mg of dextromethorphan coadministered on day 8. The mean AUC(0-infinity) and C(max) of dextromethorphan increased 11- and 7-fold, respectively, in extensive metabolizers when coadministered with cinacalcet versus placebo. Therefore, during concomitant treatment with cinacalcet, it may be necessary to consider making dose adjustments for drugs with a narrow therapeutic index that are mainly metabolized by CYP2D6.
