Simultaneous dynamic scheduling and collision-free path planning for multiple autonomous vehicles (2009)

When autonomous vehicles are deployed to perform transportation tasks within a confined space and strict time constraint, the problem of optimizing the assignment of tasks to vehicles is complicated by the need to ensure safety (they do not collide with or impede each other) and maximize the efficiency and productivity. With the increasing number of autonomous vehicles in practical settings, the ability to schedule tasks in a manner that inherently considers the effects of task allocations on space contention (which in turn compromises efficiency) is important to performance improvement. The main contribution of this paper is an approach to simultaneously conduct dynamic task allocation and collision-free path planning in an environment where multiple autonomous vehicles operate on a network of paths and where each path segment can only be occupied by one vehicle at a given instant. In particular, a generic algorithm for effective task allocation is investigated and applied in conjunction with an application-specific objective function. The proposed approach is able to solve the dynamic scheduling, planning and collision avoidance problem in an integrated way such that the overall productivity of the transportation system is improved. Simulation results based on a real-world industrial material handling environment demonstrate the feasibility and effectiveness of the proposed method.

Sequential Changes in Lipid Fluidity and Phase Properties of Microsomal Membranes from Senescing Rose Petals (1982)

Cytoplasmic membrane deterioration during petal senescence of cut rose flowers entails a sequence of interrelated physical changes in the lipid bilayer. Wide angle X-ray diffraction revealed that microsomal membranes from flowers at the tight bud stage (day 1) contained liquid-crystalline lipid and only traces of gel phase lipid. However, with advancing senescence, the proportion of gel phase lipid increased, particularly between days 6 and 9. The lipid phase transition temperature also increased during senescence from 38 �C at day 1 to 48 �C at day 9. An order parameter (S), reflecting molecular order close to the membrane surface and determined by electron spin resonance (ESR) of microsomal membranes labelled with 5-doxyl stearate, increased during the early stages of senescence between days 1 and 3. The rotational correlation time (τ<inf>c</inf>), a motion parameter obtained from microsomal membranes labelled with 16-doxyl stearate, increased throughout senescence, reflecting a rise in lipid microviscosity deep in the hydrophobic core of the membrane bilayer. Activation energies, calculated from continuously linear Arrhenius plots of rc and reflecting the degree of molecular order in the hydrophobic core of the membrane, increased during the later stages of senescence between days 6 and 9. The physiological implications of these physical changes in the lipid bilayer are discussed.
HEAVY METAL–INDUCED OXIDATIVE STRESS IN ALGAE<sup>1</sup> (2003)

Heavy metals, depending on their oxidation states, can be highly reactive and, as a consequence, toxic to most organisms. They are produced by an expanding variety of anthropogenic sources suggesting an increasingly important role for this form of pollution. The toxic effect of heavy metals appears to be related to production of reactive oxygen species (ROS) and the resulting unbalanced cellular redox status. Algae respond to heavy metals by induction of several antioxidants, including diverse enzymes such as superoxide dismutase, catalase, glutathione peroxidase and ascorbate peroxidase, and the synthesis of low molecular weight compounds such as carotenoids and glutathione. At high, or acute, levels of metal pollutants, damage to algal cells occurs because ROS levels exceed the capacity of the cell to cope. At lower, or chronic, levels algae accumulate heavy metals and can pass them on to organisms of other trophic levels such as mollusks, crustaceans, and fishes. We review here the evidence linking metal accumulation, cellular toxicity, and the generation of ROS in aquatic environments.
Tragedy of Spirit-Empowered Heroes: A Close Look at Samson and Saul (2017)

This study is motivated by the ongoing dilemma of the ethical failures among well-known leaders of the modern Pentecostal/Charismatic movements. Through a close look at Saul and Samson, the two charismatic leaders of the Old Testament who have the most frequent references to the Spirit of God, the study probes the internal and private layers of their experience with the Spirit of God. The intention of the Spirit’s presence includes both an internal transformation as well as external tasks. The scriptural evidence demonstrates that there is no less work of the Spirit for the internal working of the recipients than the tasks of deliverance. It is their failure to receive the private and internal transformative work of the Spirit that resulted in the total failure of the heroes.
Enhancing the Efficiency of the Solid Phase Peptide Synthesis (SPPS) Process by High Shear Mixing (2018)

The brittle nature of the polymer beads used in SPPS dictates mild mixing techniques with low mass transfer. We demonstrate that vigorous overhead mechanical stirring with superior mass transfer properties kept the beads intact and significantly accelerates reaction kinetics and efficiency.
An outbreak of VHSV (viral hemorrhagic septicemia virus) infection in farmed Japanese flounder Paralichthys olivaceus in Japan (2001)

A rhabdoviral disease occurred in farmed populations of market sized Japanese flounder (hirame) Paralichthys olivaceus in the Seto Inland Sea of Japan in 1996. The causative agent was identified as viral hemorrhagic septicemia virus (VHSV) based on morphological, immunological, and genetic analyses. Diseased fish that were artificially injected with a representative virus isolate showed the same pathological signs and high mortality as observed in the natural outbreak. This is the first report of an outbreak of VHSV infection in cultured fish in Japan. Clinical signs of diseased fish included dark body coloration, an expanded abdomen due to ascites, congested liver, splenomegaly, and a swollen kidney. Myocardial necrosis was most prominent and accompanied by inflammatory reactions. Necrotic lesions also occurred in the liver, spleen and hematopoietic tissue, and were accompanied by circulatory disturbances due to cardiac failure. Hemorrhagic lesions did not always appear in the lateral musculature. Transmission electron microscopy revealed many rhabdovirus particles and associated inclusion bodies containing nucleocapsids in the necrotized myocardium. The histopathological findings indicated that the necrotizing myocarditis could be considered a pathognomonic sign of VHSV infection in Japanese flounder.
Yeast RNA Polymerase II Subunit RPB9 (2000)

The RPB9 subunit of RNA polymerase II regulates transcription elongation activity and is required for the action of the transcription elongation factor, TFIIS. RPB9 comprises two zinc ribbon domains joined by a conserved linker region. The C-terminal zinc ribbon is similar in sequence to that found in TFIIS. To elucidate the relationship between the structure and transcription elongation function of RPB9, we initiated a mutagenesis study on the Saccharomyces cerevisiae homologue. The individual zinc ribbon domains, in isolation or in combination, could not stimulate transcription by a polymerase lacking RPB9, pol IIDelta9. Mutations in the N-terminal zinc ribbon had little effect on transcription activity. By contrast, mutations in the acidic loop that connects the second and third beta-strands of the C-terminal zinc ribbon were completely inactive for transcription. Interestingly, the analogous residues in TFIIS are also critical for elongation activity. A conserved charged stretch in the linker region (residues 89-95, DPTLPR) mediated the interaction with RNA polymerase II.
Online Algorithm for Robots to Learn Object Concepts and Language Model (2016)

Humans form concept of objects by classifying them into categories, and acquire language by simultaneously interacting with others. Thus, the meaning of a word can be learned by connecting a recognized word to its corresponding concept. We consider this ability important for robots to flexibly develop knowledge of language and concepts. In this paper, we propose an online algorithm for robots to acquire knowledge of natural language and learn object concepts. A robot learns the language model from word sequences, which are obtained by the segmentation of phoneme sequences provided by a user, by using unsupervised word segmentation each time it is provided with a new object. Moreover, the robot acquires object concepts using these word sequences as well as multimodal information obtained by observing objects. The crucial aspect of our model is the interdependence of words and concepts: there is a high probability that the same words will be uttered to describe objects in the same category. By taking this relationship into account, our proposed method enables robots to acquire a more accurate language model and object concepts online. Experimental results verify this.
Multiple choice examinations (1999)

I read with interest the special communication by Hammond et al. on the issue of multiple choice examinations (MCQs) and the rationale of having negative marking for incorrect answers (Anaesthesia 1998; 53: 1105–8). Having sat many MCQs in the past, including the FRCA, I have always been convinced that guessing, even apparent ‘wild guessing’, tended to increase rather than decrease the final mark. As stated in the article, anaesthetic trainees are continually discouraged from guessing by their educators as the negative marking will result in the loss of marks. This misconception is held very strongly by a lot of MCQ candidates. I presume that the role of negative marking is to discourage guessing as guessing in clinical practice could be dangerous. In fact, negative marking simply prejudices against those candidates who fail to answer enough questions as a result of their fear of losing marks. The Royal College of General Practitioners discontinued negative marking a number of years ago when they demonstrated that it discriminated against female candidates, who tended to be more cautious with regards to guessing. In my opinion, negative marking is of no benefit whatsoever and does not improve the efficacy of the MCQ as a test of a candidate's knowledge. I feel that it is time for The Royal College of Anaesthetists to follow the lead of the MRCGP examination and drop negative marking from the Fellowship MCQ examinations.
Ex Vivo Culture of CD34+/Lin−/DR− Cells in Stroma-Derived Soluble Factors, Interleukin-3, and Macrophage Inflammatory Protein-1α Maintains Not Only Myeloid But Also Lymphoid Progenitors in a Novel Switch Culture Assay (1998)

We have demonstrated that long-term culture initiating cells (LTC-IC) are maintained in a stroma noncontact (SNC) culture where progenitors are separated from stroma by a microporous membrane and LTC-IC can proliferate if the culture is supplemented with interleukin-3 (IL-3) and macrophage inflammatory protein-1alpha (MIP-1alpha). We hypothesize that the same conditions, which result in LTC-IC proliferation, may also maintain lymphoid progenitors. Natural killer (NK) cells are of lymphoid lineage and a stromal-based culture can induce CD34+/Lin-/DR- cells to differentiate along the NK cell lineage. We developed a three-step switch culture assay that was required to demonstrate the persistence of NK progenitors in CD34+/Lin-/DR- cells assayed in SNC cultures supplemented with IL-3 and MIP-1alpha. When CD34+/Lin-/DR- progeny from the SNC culture were plated sequentially into "NK cell progenitor switch" conditions (contact with stromal ligands, hydrocortisone-containing long-term culture medium, IL-2, IL-7, and stem cell factor [SCF]) followed by "NK cell differentiation" conditions (contact with stromal ligands, human serum, no hydrocortisone, and IL-2), significant numbers of CD56+/CD3- NK resulted, which exhibited cytotoxic activity against K562 targets. All steps are required because a switch from SNC cultures with IL-3 and MIP-1alpha directly to "NK cell differentiation" conditions failed to yield NK cells suggesting that critical step(s) in lymphoid commitment were missing. Additional experiments showed that CD34+/CD33- cells present after SNC cultures with IL-3 and MIP-1alpha, which contained up to 30% LTC-IC, are capable of NK outgrowth using the three-step switch culture. Limiting dilution analysis from these experiments showed a cloning frequency within the cultured CD34+/CD33- population similar to fresh sorted CD34+/Lin-/DR- cells. However, after addition of FLT-3 ligand, the frequency of primitive progenitors able to develop along the NK lineage increased 10-fold. In conclusion, culture of primitive adult marrow progenitors ex vivo in stroma-derived soluble factors, MIP-1alpha, and IL-3 maintains both very primitive myeloid (LTC-IC) and lymphoid (NK) progenitors and suggests that these conditions may support expansion of human hematopoietic stem cells. Addition of FLT-3 ligand to IL-2, IL-7 SCF, and stromal factors are important in early stages of NK development.

Stencil technique for the preparation of thin-film Josephson devices (1978)

We describe a photoresist stencil technique that has proven to be quite reliable in the preparation of thin-film Josephson logic and memory devices. The method employs multiple layers of resist with the top layer providing patterning and the bottom layer spacing the top layer from the substrate and providing an undercut under the top layer. This method has consistently produced uniform undercuts over ∠1 in. (∠2.54 cm) sample dimensions and has been used to produce micron-sized patterns.
Improved algorithms for topic distillation in a hyperlinked environment (1998)

This paper addresses the problem of topic distillation on the World Wide Web, namely, given a typical user query to find quality documents related to the query topic. Connectivity analysis has been shown to be useful in identifying high quality pages within a topic specific graph of hyperlinked documents. The essence of our approach is to augment a previous connectivity analysis based algorithm with content analysis. We identify three problems with the existing approach and devise algorithms to tackle them. The results of a user evaluation are reported that show an improvement of precision at 10 documents by at least 45% over pure connectivity analysis.
An incremental method for computing dominant singular spaces (2001)

Introduction In many problems one needs to compute a projector on the dominant subspace of a given data matrix A of dimension m n. One can interpret the columns of the matrix A as data vectors with some energy equal to their 2-norm. Finding the dominant space of dimension k &lt; min(m; n) amounts to nding the k rst columns of the matrix U in the singular value decomposition of A: A = UV T ; U T U = I n ; V V T = V T V = I n ; = diagf 1 ; : : : n g; (1) and where the diagonal elements i of are non negative and non increa

Ink Jet Printing for Direct Mask Deposition in Printed Circuit Board Fabrication (2009)

Drop deposition has been studied over a wide range of time scales under conditions relevant to direct printing of etch resist patterns on printed circuit boards. Early-stage impact-driven spreading of 80 pl drops of UV ink and phase change resist was imaged by 20 ns duration flash-based photography, while a 27,000 fps high-speed camera was used to study the later stages of spreading up to 130 ms postimpact. The presence of an attached ligament at impact was shown to reduce the effect of impact inertia and the tendency for recoil, although this was less significant in the later, capillary phase. The effects of surface wetting appeared to be insignificant during the impact and relaxation spreading phases but dominated the behavior during capillary spreading. Cooling by conduction from the substrate was shown to be effective in arresting drop spreading for the phase-change ink on a submillisecond time scale.
Mutation of the Stargardt Disease Gene ( <i>ABCR</i> ) in Age-Related Macular Degeneration (1997)

Age-related macular degeneration (AMD) is the leading cause of severe central visual impairment among the elderly and is associated both with environmental factors such as smoking and with genetic factors. Here, 167 unrelated AMD patients were screened for alterations in ABCR, a gene that encodes a retinal rod photoreceptor protein and is defective in Stargardt disease, a common hereditary form of macular dystrophy. Thirteen different AMD-associated alterations, both deletions and amino acid substitutions, were found in one allele of ABCR in 26 patients (16%). Identification of ABCR alterations will permit presymptomatic testing of high-risk individuals and may lead to earlier diagnosis of AMD and to new strategies for prevention and therapy.
From logo-centrism to corporate branding?: the (r)evolution in organisational identity (2024)

When the archaeologists of the next millennium dig down into the landfills of the past 100 years, in between the mountains of perfectly preserved disposable diapers and other detritus of our instant civilisation, they will find mounds of unused business cards, envelopes, and letterheads. These costly rejects of corporate revamps litter the last decade of the millennium as the fall-out of countless restructuring exercises. It is not surprising that cynicism about the point of all this frenetic activity is widespread. Consultants grow fatter as corporations get leaner and meaner (but with mare up-market typefaces). In this paper, I explore the various historical phases of organisational identity work and consider what direction it might take in the future.
Optical Biosensors. Monitoring Studies of Glycopeptide Antibiotic Fermentation Using White Light Interference (2001)

This paper describes the design, characterization, and use of an optical biosensor suited for the process control of biotechnological processes. The detector principle is based on reflectometric interference spectroscopy (RIfS). RIfS enables a label-free, product-specific monitoring, with a future outline for on-line process control. The potential of the RIfS biosensor is exemplified by the qualitative and quantitative monitoring of the microbial production of vancomycin-type glycopeptide antibiotics.
A hybrid score measurement for HMM-based speaker verification (1999)

In speaker verification the world model based approach and the cohort model based approach have been used for better HMM score measurements for verification comparison. From theoretical analysis these two approaches represent two different paradigms for verification decision-making strategy. The two techniques could be combined for a better solution. In the paper we present a hybrid score measurement which combines the world model based technique and the cohort model based technique together. The method is evaluated with the YOHO database. The results show that the combination can lead a better score measurement which improves speaker verification performance. An experimental comparison between the world model based approach and the cohort model based approach with the YOHO database can also be found in the paper.
Improving the reconstruction quality with extension and apodization of the digital hologram (2009)

To suppress the aperture diffraction and spectral leakage effects in the reconstruction process of the digital hologram and to maintain the original information recorded in the hologram, a novel reconstruction method based on extension and apodization of the digital hologram is presented, by which the original hologram can be extended by filling the average intensity values of the boundary, and the extended hologram is apodized by use of the constructed window function. As a sample, the digital hologram of the static particle field is recorded and numerically extended and then apodized with the appointed window. Finally, an unabridged and clear digital holographic image is reconstructed from the extended and apodized hologram. The experimental results confirm that this method cannot only eliminate the black-and-white diffraction fringes in the reconstructed image, but also attain the unabridged image with high quality.
