Compatibility (1981)

This “paper” is a summary of the points I will raise during the SIGDOC panel on Using the New Technology at ACM '81. Because we plan a panel discussion with audience participation, I am only outlining here the subject areas I propose to discuss. Also, the problem of compatibility is not one for which there is a single “answer”—rather, there is a variety of approaches which have different advantages and disadvantages.
Improved polyvinylpyrrolidone (PVP)/graphite nanocomposites by solution compounding and spray drying (2011)

Abstract In order to evaluate the roles of graphite dispersion on the functional properties of the composites, PVP/graphite nanocomposites were prepared by blending the aqueous suspension of expanded graphite sheets and polyvinylpyrrolidone (PVP) aqueous solution by ultrasonic treatment, followed by spray drying and direct drying as a comparison individually. The effects of graphite loading and drying method on the dispersion of graphite and the resultant properties of the composites such as electrical and thermal conductivity, friction, and dynamic mechanical properties were studied. The results from transmission electron microscopy (TEM), scanning electron microscopy (SEM), and X‐ray diffraction showed that the composites prepared by fast spray drying exhibited a higher degree of exfoliation and a better dispersion of graphite sheets in the PVP matrix than the corresponding composites prepared by direct drying, leading to a conclusion that fast spray drying can effectively prevent from re‐stacking of the exfoliated graphite sheets as illustrated. As a result, dynamic mechanical thermal analysis showed significant increases in the storage modulus and glass transition temperature for the composites prepared by spray drying. Besides, the spray drying as well greatly improved the electrical and thermal conductivity of the composites. It was also found that the electrical and thermal conductivity of the composites strongly depended on the graphite dispersion, while the friction coefficient unexpectedly does not. Increasing graphite loading level might enhance the probability of graphite sheets re‐stacking, resulting in poor graphite dispersion. Copyright © 2011 John Wiley & Sons, Ltd.
The formulation of aspirin. (1971)

Unresolving severe cholestasis after LT is a key parameter predicting patient/allograft outcome. Histologically, rejection seems to overlap with biliary strictures; hence, allograft biopsy with signs of rejection should not be a reason to overlook biliary problems, in particular when biliary features are present. Only extensive radiological investigation/intervention or retransplantation prevents patient/allograft loss.
Designed Assembly and Structures and Photoluminescence of a New Class of Discrete Zn<sup>II</sup> Complexes of 1<i>H</i>‐1,10‐Phenanthroline‐2‐one (2006)

Abstract The hydrothermal reaction of 1 H ‐1,10‐phenanthroline‐2‐one (Hophen), zinc acetate, benzoic acid (Hba), and triethylamine (3.0 mL) yields the tetranuclear complex [Zn 4 (μ 3 ‐OH) 2 (ophen) 4 (ba) 2 ] ( 2 ), which features a chair‐like Zn 4 (μ 3 ‐OH) 2 cluster with two ba ligands centrosymmetrically oriented. [(OAc){Zn 3 (μ 3 ‐OH)(ophen) 3 }(ox){Zn 3 (μ 3 ‐OH)(ophen) 3 }(OAc)] ( 3 ; ox = oxalate) was isolated when less triethylamine (1.0 mL) was used. Two Zn 3 (μ 3 ‐OH)(ophen) 3 clusters in 3 are linked together by an oxalate to form a dumbbell‐like structure in which the acetate and oxalate ligands point outward from the Zn 3 (μ 3 ‐OH)(ophen) 3 cluster with an acute bending angle. A geometric analysis reveals that Zn 3 (μ 3 ‐OH)(ophen) 3 and dicarboxylate with an obtuse bending angle cannot form an infinite zigzag chain, whereas the ring isomer can. With isophthalate (ipa), thiophene‐2,5‐dicarboxylate (tda), and 4,4′‐oxybis(benzoate) (oba) instead of the acetate of 3 three new complexes, namely [{Zn 3 (μ 3 ‐OH)(ophen) 3 }(ipa) 2 {Zn 3 (μ 3 ‐OH)(ophen) 3 }] · 0.5H 2 O ( 4 ), [{Zn 3 (μ 3 ‐OH)(ophen) 3 }(tda) 2 {Zn 3 (μ 3 ‐OH)(ophen) 3 }] ( 5 ), and [{Zn 3 (μ 3 ‐OH)(ophen) 3 }(oba) 2 {Zn 3 (μ 3 ‐OH)(ophen) 3 }] ( 6 ), were obtained in which two Zn 3 (μ 3 ‐OH)(ophen) 3 clusters are linked by a pair of ipa, tda, or oba ligands to form isostructural, cluster‐based 2:2 metallomacrocycles. Photoluminescence studies of 2 – 6 revealed that their luminescent properties are derived from ophen‐based π‐π* excited states. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Towards a Model of Labour Turnover and Job Choice (1974)

The main purpose of writing this paper is to try to suggest, in conceptual terms at least, a model for the labour turnover process. The model outlined in this paper is seen as a single part of the total supply and demand for labour in the macro‐economy.

An automated micro measurement system for integrated circuit masks (1970)

A computer controlled system for making positional measurements on a glass plate to an accuracy of 1 μm is described. Through the use of a computer, the short-comings of the Do-all coordinate measuring machine (CMM) are overcome allowing the effective use of the inherent accuracy of the CMM. The result is a measurement system having greatly enhanced capability. A plate having an array of 208 data points can be measured in about two hours, whereas without the computer control measurement of such a large array with the CMM is not feasible.
An efficient hybrid cache coherence protocol for shared memory multiprocessors (2002)

This paper presents a new tree-based cache coherence protocol which is a hybrid of the limited directory and the linked list schemes. By utilizing a limited number of pointers in the directory, the proposed protocol connects the nodes caching a shared block in a tree fashion. In addition to the low communication overhead, the proposed scheme also contains the advantages of the existing bit-map and tree-based linked list protocols, namely, scalable memory requirement and logarithmic invalidation latency. We evaluate the performance of our protocol by running four applications on an execution-driven simulator. Our simulation results show that the performance of the proposed protocol is very close to that of the full-map directory protocol.
NEST-SITE SELECTION AND NEST SURVIVAL OF TWO WOODPECKER SPECIES IN PONDEROSA-PINE DOMINATED FORESTS (2007)

Management of woodpecker populations requires knowledge of nesting habitat and vital rates in different forest conditions. We examined nest-site selection and nest survival for two woodpeckers, northern flicker (Colaptes auratus) and hairy woodpecker (Picoides villosus) at three locations in ponderosa-pine forests of the interior Columbia River Basin. Our goals were to: (1) characterize the range of habitat conditions available to nesting woodpeckers in our study area; (2) determine which habitat features best discriminated between nest and non-nest plots, and (3) establish which habitat features most influenced daily nest survival. Northern flickers and hairy woodpeckers were more likely to choose snags than live trees. Both species used larger diameter snags than those available at random. Nest snags tended to be in plots that had higher snag densities and lower live tree densities. For northern flickers, a model of constant daily survival received more support than any model containing habitat covariates.
Signalling pathways in cardiac myocyte hypertrophy. (2001)

In response to a requirement for increased contractile power in vivo, mammalian cardiac myocytes adapt through a hypertrophic response (cell enlargement in the absence of cell division). This response can be simulated by exposing isolated myocytes in primary culture to alpha-adrenergic agonists or the vasoactive peptide, endothelin-1. The signalling pathways responsible for hypertrophic growth have been actively studied, and it is likely that reversible protein phosphorylation and dephosphorylation are involved. Three signalling pathways show particular potential as regulators of the response, ie protein kinase C (PKC), mitogen-activated protein kinase (MAPK) cascades, and calcineurin. These species are thought to regulate the rate and specificity of gene transcription ultimately through modifying the transactivating activity of nuclear transcription factors. There are three pertinent MAPK cascades, the extracellular signal-regulated kinase (ERK) cascade, the c-Jun N-terminal kinase (JNK or SAPK1) cascade, and the p38-MAPK (SAPK2-5) cascade. PKC participates in the activation of the ERK cascade but does not contribute significantly to the activation of the two remaining cascades. Calcineurin (or protein phosphatase 2B) is activated by increases in [Ca2+i] through the [Ca2+]-sensing protein, calmodulin. In this review, I discuss the evidence for and against the involvement of these signalling proteins in the induction of myocyte hypertrophy and emphasize that the ERK cascade should perhaps feature more widely in the collective consciousness.
Multiple gene knock-down by a single lentiviral vector expressing an array of short hairpin RNAs (2006)

RNA interference (RNAi), mediated by short double-stranded RNAs, is a powerful mechanism for posttranscriptional gene silencing. Sustained expression of short hairpin RNA (shRNA) can be accomplished in mammalian cells by viral delivery systems. Using lentiviral constructs, stable gene silencing is established both in dividing and non-dividing cells. Targeting one single gene can lead to the development of escape mutants or may be insufficient to silence redundant pathways. Therefore, simultaneous targeting of multiple genes may be necessary. We have generated a lentiviral vector-based system for expression of multiple shRNAs from a single viral vector, which also encodes an EGFP reporter protein. We show that knock-down of each single gene from multiple target vectors is achieved at an efficiency comparable to that obtained after transduction using single target viral vectors. In this way, we were able to knock-down several members of the human Rho-family GTPases in T cells. Double and triple knock-down persisted after multiple passages of the cells. The ability to inhibit two or more genes simultaneously from one single expression vector further widens the application spectrum of RNAi, both in functional studies and therapeutic strategies.
Analysis of the allergenic proteins in black tiger prawn ( <i>Penaeus monodon</i> ) and characterization of the major allergen tropomyosin using mass spectrometry (2010)

Crustaceans are the third most prevalent cause of food-induced anaphylaxis after peanuts and tree nuts. The severity of the allergenic proteins depends mainly on the amino acid sequence that induces production of IgE antibodies. In black tiger prawn (Penaeus monodon), the crude protein extract was profiled and its allergenic potency was examined against patient's sera. Proteins having strong immunoreactivity with patient's IgE were characterized using peptide mass fingerprinting (PMF). Tropomyosin (TM) (33 kDa), myosin light chain (20 kDa), and arginine kinase (40 kDa) were identified as allergenic proteins. Tropomyosin, the most abundant and potent allergen, was purified using ion-exchange chromatography for de novo sequencing experiments. Using bottom up tandem mass spectrometry, the full amino acid sequence was achieved by a combination of matrix-assisted laser desorption/ionization (MALDI) and electrospray ionization (ESI) tandem mass spectrometry (QqToF). Myosin light chain and arginine kinase were also characterized, and their related peptides were de novo sequenced using the same approach. The immunological reactivity of the crude prawn extracts and purified TM samples were analyzed using a large number of patients' sera. A signature peptide was assigned for the TM protein for future quantification work of black tiger prawn TM levels in different matrices (i.e. water, air, food) in the seafood industry.
The Structure of Scientific Literatures I: Identifying and Graphing Specialties (1974)

In this paper we report a first experiment using a new computer-based technique to identify clusters of highly interactive documents in science. We contend that these clusters represent the scientific specialties which currently exhibit high levels of activity. This technique, we believe, opens the way to a systematic exploration of the entire specialty structure of science, including both the internal structure of specialties and their relationship to one another. That science is a mosaic of specialties, and not a unified whole, either socially or intellectually, is a frequently made assumption, but only recently has this infra-structure of science become the subject of systematic study. Most scientists have intuitive notions about the subdivisions of their fields, but no observer, however broadly trained, can gain an overall perspective on the scientific mosaic. A series of recent studies has called attention to the importance of specialties as 'building blocks' of science. Crawford's paper' described how one specialty, sleep research, is effectively organized as a communication system around certain key individuals and research centres. Griffith and Mullins2 have argued that major changes in a variety of disciplines have been generated within small, socially coherent groups. *325 Chestnut Street, Philadelphia, Pennsylvania, I 9I o6, USA.

Abstract In Parts I and 10.1007/978-3-030-85532-1_Part2 , the scientific breakthrough of ammonia synthesis was described in terms of a confluence of factors leading to an arena of research mature enough for advancement—it is a dynamic encapsulated in the concept of The Haze .
Program visualization: Graphical support for software development (1985)

This article describes a prototype program visualization (PV) enviromnent that we have developed. The prototype is an "umbrella" in the sense that it is not targeted to support any one software development methodology. Rather, it provides basic PV tools that can be used in the service of the programmer's chosen methodology. Our system was designed to support progmming in C, although large portions ofit are independent of the software development language. The prototype itself is implemented in C and runs on a VAX 11/780 under UCB Unix Version 4.2.

Multi-constellation GBAS: How to benefit from a second constellation (2016)

In this paper we analyze and discuss the impact of ionospheric scintillations and multipath on the availability of the current single-frequency single-constellation Ground Based Augmentation System (GBAS). Scintillation effects, which usually occur around plasma bubbles, cause the receiver to lose lock of one or more satellites, leading to potentially unfavorable satellite geometries for an airborne user. We simulate different bubble dimensions and distinct locations of the bubble in the sky in order to illustrate that the use of a second constellation improves the performance of the system in terms of availability for the situations where the single constellation system is unavailable. Furthermore, we investigate the impact of multipath in the availability of the system. During the touch-down and roll-out of the aircraft on the runway, multipath coming from ground reflections becomes important, especially for low elevation satellites producing large position errors. The results show that the use of a second constellation allows the removal of low elevation satellites from the position solution, which are typically strongly affected by multipath. Elevation masks of 10° or even 15° do not degrade the availability of the dual-constellation system in any of the scenarios considered.
Deformation of grain boundaries in polar ice (2004)

The ice microstructure (grain boundaries) is a key feature used to study ice evolution and to investigate past climatic changes. We studied a deep ice core, in Dome Concordia, Antarctica, which records past mechanical deformations. We measured a "texture tensor" which characterizes the pattern geometry and reveals local heterogeneities of deformation along the core. These results question key assumptions of the current models used for dating.

Firstly, several methods of computer drawing were compared in this paper. Then, a new method of how to implement dynamic displaying physiological information in real time in medical monitoring system with GDI functions was described.
Nucleotide sequence of the gene for the ferrienterochelin receptor FepA in Escherichia coli. Homology among outer membrane receptors that interact with TonB. (1986)

We have determined the nucleotide sequence of the Escherichia coli fepA gene, which codes for the outer membrane receptor for ferrienterochelin and colicins B and D. The predicted FepA polypeptide has a molecular weight of 79,908 and consists of 723 amino acids. A 22-amino acid leader or signal peptide preceded the mature protein. With respect to overall composition, hydropathy, net charge and distribution of nonpolar segments, the FepA polypeptide was typical of other E. coli outer membrane proteins, except that FepA contained 2 cysteine residues. Comparison of the deduced amino acid sequence of FepA with that of three other TonB-dependent receptors (BtuB, FhuA, and IutA) revealed only a few regions of sequence homology; one of these included the amino-termini. An amino acid substitution within the conserved amino-terminal region of BtuB resulted in production of a receptor that had normal binding functions but was incapable of energy-dependent transport of vitamin B12. This result suggests that the amino-terminal end of these four polypeptides is involved in interaction with the TonB protein or another step of energy transduction. Three other regions of homology were shared among the four proteins: one near residues 50 to 70, another at about residue 100 to 140, and the last between 20 and 40 amino acid residues from the carboxyl terminus. The function of these three regions remains speculative.
Genetic Algorithm for Finding Minimal Cost Light Forest of Multicast Routing on WDM Networks (2008)

Wavelength division multiplexing (WDM) is an important technique to make use of the large amount of bandwidth in optical fibers to meet the bandwidth requirements of applications. Multicast is the transmission of information from one source to multiple destinations simultaneously. Given a multicast request in a WDM network, the goal is to find a set of light trees, the assigned wavelengths of light trees, and construct a light forest . In this paper, the minimal cost multicast routing problem (MCMRP) on WDM networks with tap-and-continue (TaC) nodes is defined and studied. A new cost model which consists of the wavelength usage and communication cost is defined. The objective is to minimize the sum of the cost of used wavelengths and the communication cost of the light forest . Specifically, the formulation for the WDM multicast routing problem is given. Because the MCMRP is NP‐hard, two genetic algorithms (GAs) are proposed to solve this problem. In the proposed GAs, a path-oriented encoding chromosome is used to represent the routing paths. These routing paths are used to construct source‐based light forests to represent a feasible solution to the multicast request. Moreover, to speed up the convergence of GAs, a farthest-first greedy heuristic algorithm is proposed and used to generate one of the initial chromosomes. Simulation results demonstrate that the proposed GAs can run efficiently.
Quantification of Vessel Density in Retinal Optical Coherence Tomography Angiography Images Using Local Fractal Dimension (2016)

A novel implementation of local fractal dimension to calculate vessel density and FAZ area was demonstrated. Age did not impact vessel density but sectoral analyses showed greater vessel density in the inferior zone.
The Characteristics of UV Strength According to Corona Discharge From Polymer Insulators Using a UV Sensor and Optic Lens (2011)

Inspections and diagnoses of corona discharges are important in order to prevent electrical faults of external insulation in power systems. This paper studies the measurement of ultraviolet rays (UV) strength of corona discharges on polymer insulators using a UV sensor with an optic lens. The data have been compared with the images of a UV camera. The UV signal by corona discharge was detected from more than 60 kV, which was equivalent to around 37.5% of the breakdown voltage. The UV strength increased with increasing high voltage and the supplying dc voltage. Also, UV image was observed. However, the longer the distance was, the greater the reduction in UV signals would be. The robust, inexpensive sensor can detect corona discharge activity on polymer insulators when the applied voltage exceeds 37.5% of the breakdown voltage.
Prognostic value of immunocytochemical estimation of estrogen receptor (ER) and of pS2 estrogen-dependent protein in cells of mammary ductal carcinoma. Analysis of five-year course of the disease. (2001)

The pS2 protein belongs to the so called estrogen-dependent proteins, which appear in cells as a result of estrogen stimulation. The present study was aimed at determining prognostic value of estrogen receptor (ER) and pS2 protein expression in mammary cancer cells. The immunocytochemical reactions were performed in paraffin sections of tissue samples from 62 patients with ductal mammary carcinoma using monoclonal antibodies against ER and pS2. The analysis included also survival time of the patients, determined during the five-year observations. The studies documented a correlation between survival time and the level of ER expression (p=0.014) and absence of correlations between survival time and pS2 expression (p=0.55). The results indicate that evaluation of ER expression in mammary cancer cells may assist in defining prognosis of the patients while parallel estimation of pS2 expression in the cells is useless in this respect.
