Designing Energy Display Formats for Civil Aircraft: Reply to Amelink, Mulder, van Paassen, and Flach (2007)

Abstract In their recent article on total energy-based flight-path displays, Amelink, Mulder, van Paassen, and Flach (2005) Amelink, M. H. J., Mulder, M., van Paassen, M. M. and Flach, J. 2005. Theoretical foundations for ato-tal energy-based perspective flight-path display. International Journal of Aviation Psychology, 15: 205–231. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar] quite rightly pointed out that energy issues are covered in descriptions of the piloting task, which tend to be based on the machine's behavior, rather than the system's functions and their relation to the goals to be achieved. Taking a more holistic approach, referred to by Amelink et al. as ecological interface design, will lead to greater pilot situation awareness, flight safety, and efficiency. We have addressed this in our work on designing energy display formats for civil aircraft, and would like to add to the work of Amelink et al. in a reply to their article.

Paths to selection on life history loci in different natural environments across the native range of Arabidopsis thaliana (2013)

Selection on quantitative trait loci (QTL) may vary among natural environments due to differences in the genetic architecture of traits, environment-specific allelic effects or changes in the direction and magnitude of selection on specific traits. To dissect the environmental differences in selection on life history QTL across climatic regions, we grew a panel of interconnected recombinant inbred lines (RILs) of Arabidopsis thaliana in four field sites across its native European range. For each environment, we mapped QTL for growth, reproductive timing and development. Several QTL were pleiotropic across environments, three colocalizing with known functional polymorphisms in flowering time genes (CRY2, FRI and MAF2-5), but major QTL differed across field sites, showing conditional neutrality. We used structural equation models to trace selection paths from QTL to lifetime fitness in each environment. Only three QTL directly affected fruit number, measuring fitness. Most QTL had an indirect effect on fitness through their effect on bolting time or leaf length. Influence of life history traits on fitness differed dramatically across sites, resulting in different patterns of selection on reproductive timing and underlying QTL. In two oceanic field sites with high prereproductive mortality, QTL alleles contributing to early reproduction resulted in greater fruit production, conferring selective advantage, whereas alleles contributing to later reproduction resulted in larger size and higher fitness in a continental site. This demonstrates how environmental variation leads to change in both QTL effect sizes and direction of selection on traits, justifying the persistence of allelic polymorphism at life history QTL across the species range.
Protein structural alphabets: beyond the secondary structure description (2001)

The considerable increase of the protein structural database allows to cross the line from the classical secondary structure description of proteins. While still confronted with numerous problems, defining structural alphabets is an emerging concept in the field of protein structure analysis. It is an attempt to objectively classify the whole set of conformations occurring in protein structures described by small overlapping fragments. It is expected to lead to a better understanding of protein architecture and to open new opportunities for protein structure prediction.

Fast two-frame multiscale dense optical flow estimation using discrete wavelet filters (2003)

A multiscale algorithm with complexity O(N) (where N is the number of pixels in one image) using wavelet filters is proposed to estimate dense optical flow from two frames. Hierarchical image representation by wavelet decomposition is integrated with differential techniques in a new multiscale framework. It is shown that if a compactly supported wavelet basis with one vanishing moment is carefully selected, hierarchical image, first-order derivative, and corner representations can be obtained from the wavelet decomposition. On the basis of this result, three of the four components of the wave let decomposition are employed to estimate dense optical flow with use of only two frames. This overcomes the "flattening-out" problem in traditional pyramid methods, which produce large errors when low-texture regions become flat at coarse levels as a result of blurring. A two-dimensional affine motion model is used to formulate the optical flow problem as a linear system, with all resolutions simultaneously (i.e., coarse-and-fine) rather than the traditional coarse-to-fine approach, which unavoidably propagates errors from the coarse level. This not only helps to improve the accuracy but also makes the hardware implementation of our algorithm simple. Experiments on different types of image sequences, together with quantitative and qualitative comparisons with several other optical flow methods, are given to demonstrate the effectiveness and the robustness of our algorithm.
Hypoglycemic Compounds as Appetite Stimulants for Baby Pigs (1959)

A series of eight experiments involving 162 early weaned baby pigs was conducted in an attempt to determine if feed consumption could be stimulated by experimental hypoglycemia. Tolbutamide failed to produce hypoglycemia; therefore, no conclusive results were obtained regarding the relationship between blood glucose concentration and feed consumption. Tolbutamide demonstrated active hypoglycemic properties when administered orally by capsule to fasted pigs (500 or 1000 mg./pig). When mixed in the ration at the rate of 800 mg. per lb. it reduced rate of growth significantly. It did not appear to be toxic at the levels studied. Insulin injected in one experiment at the rate of 0.5 and 1.0 unit per kg. body weight every 12 hours produced hypoglycemia and also reduced feed consumption and rate of gain. Feed consumption and average daily gains were not stimulated by any of the treatments studied.
The Lagrangian Parcel Dynamics of Moist Symmetric Instability (1983)

A simple model describing the slantwise ascent of a two-dimensional horizontal air tube Subject to moist symmetric instability is developed under the assumptions that the Froude number is small and that mixing is absent. It is shown that, in general, the horizontal velocities attained by the tube are comparable to those of the mean flow and that vertical velocities of up to a few meters per second are possible. The tube ascends slantwise in such a way that its buoyancy remains nearly zero, unless the environment is my very nearly moist adiabatic, in which case ascent at an angle of 45° to the vertical is preferred. Results of the analysis support the contentions of Bennetts and Hoskins and Emanual that moist symmetric instability is the cause of some mesoscale rainbands. In a companion paper, it is demonstrated that the stability of the moist baroclinic atmosphere to two-dimensional slantwise displacements of arbitrary magnitude can be approximately assessed by reversibly lifting parcel along surfaces of constant angular momentum and comparing their density with that of their environment.
Vybrané modely zásob a ich riešenie v MS Excel (2011)

Supplies are in the economy seen as wastage. Economic subject are therefore trying to create conditions in which inventory level is as low as possible. The area of inventory control includes many models for calculation of the optimal values of the ordered quantity, minimum costs etc. For example price discount model or model with the possibility of temporary lack of inventory in store. The computational complexity of these models is not difficult, because there are many simple formulas. The theoretical part describes selected inventory model in more details. The practical part, which is prepared in MS Excel using macros and VBA for Excel, follows up it and shows the application of models in practice.
Case study: Biofiltration of styrene and butylacetate at a dashboard manufacturer (1999)

Abstract Holzindustie Bruchsal (HIB) was required to treat moderate levels of styrene emissions from their plastic dashboard manufacturing process. After evaluating many types of control technologies, HIB decided to install a Bioton biofiltration system from Monsanto Enviro‐Chem Systems Inc. (MEC). After the installation of the Bioton biofilter, HIB and MEC learned that large amounts of butylacetate were also present in the off‐gas stream. The presence of butylacetate was found to have inhibitory effects on the removal of styrene. Therefore, MEC performed a series of pilot and laboratory studies to determine if a bacteria strain could be identified that would be capable of removing styrene in the presence of butylacetate. It was found that a specific bacteria strain was capable of achieving high levels of styrene removal without inhibition from butylacetate in laboratory and pilot testing. This strain was inoculated into the full scale system. After acclimation, the full scale inoculation produced a consortium of bacteria that biologically removed the styrene from the dashboard manufacturing process in the presence of butylacetate.
Utility of Organotypic Slices in Parkinson's Disease Research (2011)

Parkinson's disease (PD) is a chronic and progressive neurodegenerative disease of unknown etiology. The pathology involves a degeneration of dopaminergic neurons of the substantia nigra with consequent dopamine (DA) deficiency and neurodegeneration of striatal neurons. The most effective treatments target compensation for the DA deficit. Among the different strategies applied, the most used is pharmacological substitutive treatment with levodopa (L-DOPA). Nevertheless, all current treatments may be considered palliative and not curative.

Blockchain and Semi-Distributed Learning-Based Secure and Low-Latency Computation Offloading in Space-Air-Ground-Integrated Power IoT (2021)

Power systems impose stringent security and delay requirements on computation offloading, which cannot be satisfied by existing power Internet of Things (PIoT) networks. In this paper, we tackle this challenge by combining blockchain, space-air-ground integrated PIoT (SAG-PIoT) and machine learning. Low earth orbit (LEO) satellites assist in broadcasting a consensus message to reduce the block creation delay, and unmanned aerial vehicles (UAVs) provide flexible coverage enhancement. Specifically, we propose a Blockchain and semi-distributed leaRning-based secure and low-latency electromAgnetic interferenCe-awarE computation offloading algorithm (BRACE) to minimize the total queuing delay under the long-term security constraint. First, the task offloading is decoupled from the computational resource allocation by Lyapunov optimization. Second, the task offloading problem is solved by the proposed federated deep actor-critic-based electromagnetic interference-aware task offloading algorithm (FDAC-EMI). Finally, the resource allocation problem is solved by smooth approximation and Lagrange optimization. Simulation results verify that BRACE achieves superior delay and security performance.
Enhanced corrosion resistance of additively manufactured stainless steel by modification of feedstock (2022)

Abstract Additive manufacturing (AM) is an emerging technology to produce engineering components. However, the major challenge in the practical application of AM is the inconsistent properties of additively manufactured components. This research presents a strategy of feedstock modification to improve the corrosion performance of selective laser melted (SLM) 316L stainless steel (SS). Modified feedstock powders were produced by ball-milling of commercial-316LSS powder with 1wt.% chromium nitride (CrN). The SLM coupons produced from modified feedstock powders (SLM-316L/CrN) exhibited significantly improved corrosion performance, as evident from the high pitting and repassivation potentials and absence of metastable pitting. The microstructural characterization revealed fine oxide-inclusions comprising Si, Mn, and S in SLM-316L and only Si and Mn in SLM-316L/CrN. The absence of sulfur-containing oxide-inclusions in SLM-316L/CrN and refined cellular structure, and the change in chemical composition were attributed to corrosion resistance enhancement due to the CrN addition.
Phylogenetic Analysis of the Spider Mite Sub-Family Tetranychinae (Acari: Tetranychidae) Based on the Mitochondrial COI Gene and the 18S and the 5′ End of the 28S rRNA Genes Indicates That Several Genera Are Polyphyletic (2014)

The spider mite sub-family Tetranychinae includes many agricultural pests. The internal transcribed spacer (ITS) region of nuclear ribosomal RNA genes and the cytochrome c oxidase subunit I (COI) gene of mitochondrial DNA have been used for species identification and phylogenetic reconstruction within the sub-family Tetranychinae, although they have not always been successful. The 18S and 28S rRNA genes should be more suitable for resolving higher levels of phylogeny, such as tribes or genera of Tetranychinae because these genes evolve more slowly and are made up of conserved regions and divergent domains. Therefore, we used both the 18S (1,825-1,901 bp) and 28S (the 5' end of 646-743 bp) rRNA genes to infer phylogenetic relationships within the sub-family Tetranychinae with a focus on the tribe Tetranychini. Then, we compared the phylogenetic tree of the 18S and 28S genes with that of the mitochondrial COI gene (618 bp). As observed in previous studies, our phylogeny based on the COI gene was not resolved because of the low bootstrap values for most nodes of the tree. On the other hand, our phylogenetic tree of the 18S and 28S genes revealed several well-supported clades within the sub-family Tetranychinae. The 18S and 28S phylogenetic trees suggest that the tribes Bryobiini, Petrobiini and Eurytetranychini are monophyletic and that the tribe Tetranychini is polyphyletic. At the genus level, six genera for which more than two species were sampled appear to be monophyletic, while four genera (Oligonychus, Tetranychus, Schizotetranychus and Eotetranychus) appear to be polyphyletic. The topology presented here does not fully agree with the current morphology-based taxonomy, so that the diagnostic morphological characters of Tetranychinae need to be reconsidered.

SQUID amplifiers (2014)

Abstract This chapter treats the concrete example of the microwave SQUID, a practical quantum-limited amplifier. The appeal of the SQUID is that it is sufficiently sophisticated to be used in a variety of applications, yet sufficiently simple to allow a detailed analysis of the origin of noise and its processing through the active elements of the device. In particular, the noise of the SQUID can be understood as the mixed-down counterpart of the Johnson noise of the SQUID resistors in the vicinity of the Josephson frequency and its harmonics. The ultimate performances of the microwave SQUID amplifier are discussed.
Infrared Spectroscopy using a Photoacoustic Cell (1979)

Photoacoustic spectroscopy is a technique useful for the study of solid and liquid samples when the samples are difficult to analyze by conventional infrared techniques, such as compressed KBr pellets, diffuse reflectance and attenuated total reflectance. A photoacoustic cell designed by Blank and Wakefield [1] and shown in Figure 1 is described. The magnitude of the signal in the photoacoustic cell is proportional to the amount of photon flux emanating from the sample. Therefore, a close correspondence exists between the strength of the acoustic signal and the amount of light absorbed by the sample. The photoacoustic cell has been used as an accessory with both a constant and variable mirror scan Michelson interferometer.
A triple-level wired 24K-gate CMOS gate array (1985)

A 24K-gate CMOS gate array has been developed using triple-level wiring and a hierarchical layout method. A typical delay time is 1.6 ns with a fanout of 3 and a 3-mm metal interconnect length. The master chip was designed to be freely divided into blocks. A previously developed digital signal processor has been realized on the array. The design time was reduced to 25% of the normal design cycle although the chip size is 3.3 times larger than was realized by a handcrafted design.
Sex and Age Differences in the Distribution of 14C-Sterigmatocystin in Immature and Mature Rats (1985)

Sterigmatocystin, a mycotoxin produced by several fungi, is carcinogenic when injected subcutaneously in rats. The potential of sterigmatocystin as a contaminant to human foodstuffs makes understanding its absorption, distribution, metabolism, and excretion characteristics desirable. Single doses (8 mg/kg) of 14 C-sterigmatocystin were dissolved in wheat germ oil and administered orally to immature (50–150 g) and mature (200–300 g) rats of both sexes. Five rats of each sex and age group were sacrificed at 3, 6, 12, 48, and 96 hours after dosing. Biological specimens were collected and analyzed for total radioactivity. The differences in tissue levels of 14 C-sterigmatocystin due to age and sex were examined using Tukey's paired comparison procedure for the mean area under the tissue level vs. time curves. Statistically significant differences in the gastrointestinal tract tissue levels were observed in 70% or more of these tissues when comparing mature males vs. mature females and immature females vs. mature females. Age and sex differences were also observed in 30% or less of the organ tissues in the other comparisons made. The sterigmatocystin plasma levels vs. time curves for each group have at least two distinct peaks that may be indicative of enterohepatic recirculation. The plasma levels obtained in the male rats are consistently higher than those in the females.
Kinetic Proofreading of Cytoskeletal Structures (2010)

This cross-sectional bio-behavioral survey conducted with 853 female sex workers (FSW) aimed to examine differences in use of HIV health services, testing and prevalence among migrant and national FSW. A quarter of undocumented FSW had never used National Health Service (NHS) and 15 % never tested for HIV, significantly more than nationals (p < 0.001 and p = 0.024, respectively). HIV infection was self-reported by 11.9 % of nationals, 1.8 % of documented and 0.8 % of undocumented migrants (p < 0.001). The HIV rapid test was reactive in 13.6 % of undocumented, 8.0 % of nationals and 2.3 % of documented. A higher proportion of migrants were unaware of their positive serostatus compared to nationals. Ever had HIV testing was less likely among undocumented, who never used the NHS and who didn't know where to go if suspected being HIV-infected. Promoting early diagnosis with linkage to care among migrant FSW should be supported, while developing health services better tailored to their needs.
