The difference between the sample pressure and apparent pressure was calibrated by (1) studying the friction decay in the hysteresis loop defined by the relationship between apparent ("nominal") pressure and piston position in the compression and decompression cycles, and (2) determining the melting temperature of LiCl by DTA in pressure cells similar to those used in the reversal experiments and comparing the results with those determined in the gas apparatus. The equilibrium transition boundary can be expressed as P (kbar) = 21.945 (±0.1855) + 0.006901 (±0.0003)T (K). It is subparallel to, but ∼1.5 kbar higher than, the transition boundary determined by Bohlen and Boettcher (1982). We have also retrieved the entropy [39.56 ± 0.2 J/(mol·K)] and enthalpy of formation (−907.25 ± 0.007 kj/mol) from elements of coesite at 1 bar, 298 K, from our phase-equilibrium data and selected thermochemical data from the literature. From the characteristics of the hysteresis loop we conclude that the often-used practice of maintaining a constant nominal pressure by repeated pressure adjustment during an experiment leads to variation of pressure on the sample.

The effects of two inositol (1,4,5)-trisphosphate 5-phosphatase inhibitors on thyrotropin releasing hormone stimulated inositol (1,4,5)-trisphosphate production in GH3 cells. (1995)

The effects of FLA99 and EWP840, two disulfiram analogs which potently inhibit Ins(1,4,5)P3 5-phosphatase, upon basal and thyrotropin-releasing hormone (TRH)-stimulated inositol (1,4,5)-trisphosphate (Ins(1,4,5)P3) levels were investigated. Neither test compound affected the characteristics of the [3H]Ins(1,4,5)P3 binding site used in the competitive protein binding assay of Ins(1,4,5)P3 levels. In rat GH3 pituitary cell suspensions, TRH (100 nM) produced a large and time-dependent increase in Ins(1,4,5)P3 concentration, the maximum response being obtained within 5 seconds of stimulation in these cells. Neither FLA99 (100, 300 and 1000 microM) nor EWP840 (100 microM) produced obvious effects on the Ins(1,4,5)P3 response to TRH stimulation. Higher concentrations of EWP840 (300 and 1000 microM) abolished the Ins(1,4,5)P3 response to TRH stimulation. The lack of effect of the 5-phosphatase inhibition in the cells may indicate that 5-phosphatase is not the major metabolic pathway of this second messenger in this cell line under the assay conditions used.
An asynchronous digital demodulator for TDMA (2002)

BNR Europe Limited has developed a digitally realised demodulator for use in Time Division Multiple Access mobile communication systems. This is aimed particularly at low power, low cost in-building wireless, specifically the DECT system, and is compatible with other common angle modulation standards. The demodulator includes sampling at IF, digital down conversion and phase discrimination followed by digital timing recovery and burst correlation. The demodulator deals with the problem of variable burst to burst timing requiring fast capture of the optimum bit timing position with a minimum overhead. This is achieved by novel symbol timing estimation using an asynchronous system clock avoiding the need for storage of the entire burst. The paper describes the principles of the design together with aspects of its practical implementation as relevant. The paper concludes with a discussion of the measured performance.
Hawkes Processes with Stochastic Excitations (2016)

We propose an extension to Hawkes processes by treating the levels of self-excitation as a stochastic differential equation. Our new point process allows better approximation in application domains where events and intensities accelerate each other with correlated levels of contagion. We generalize a recent algorithm for simulating draws from Hawkes processes whose levels of excitation are stochastic processes, and propose a hybrid Markov chain Monte Carlo approach for model fitting. Our sampling procedure scales linearly with the number of required events and does not require stationarity of the point process. A modular inference procedure consisting of a combination between Gibbs and Metropolis Hastings steps is put forward. We recover expectation maximization as a special case. Our general approach is illustrated for contagion following geometric Brownian motion and exponential Langevin dynamics.
Evaluation of a Paper Mulch Made from Recycled Materials as an Alternative to Plastic Film Mulch for Vegetables (1996)

The objective of this study was to explore the feasibility of a paper film mulch fabricated from recycled waste products as an alternative to plastic film mulch for vegetable crops. Experiments were conducted to determine whether treatment with vegetable oil and/or elemental sulfur would retard the breakdown of mulch paper in contact with soil. Both unused and waste cooking oil significantly delayed paper decomposition and loss of tensile strength in laboratory and greenhouse tests, and sulfur further retarded breakdown. Oil treatment increased light transmission of kraft paper. In field experiments, soil temperatures were significantly higher under oiled paper than in bare soil or unoiled paper, whereas this was not true for black polyethylene (PE) mulch. However, increased light penetration also allowed weed growth beneath the oiled paper, which exerted pressure against the film, causing it to tear at about the same time that unoiled paper failed due to decay at the soil line. Sulfur also did not increase mulch longevity under field conditions. Tomatoes [Lycopersicon esculenrum (L.) Mill.] grown in a commercially available black paper mulch showed similar yields and earliness to tomatoes grown in black PE mulch, even though Ule latter resulted in slightly higher soil temperatures. The black paper mulch is considerably more expensive than black PE, but recycled kraft paper can be obtained in large rolls at lower per-hectare cost than plastic film mulches.
The design of Sampa [high level support of distributed applications] (2002)

We present some of the design goals and the architecture of Sampa. Sampa stands for System for Availability Management of Process-based Applications. The goal of Sampa is to provide a high-level support for the management of distributed applications and services implemented on the top of the OSF Distributed Computing Environment (DCE). Sampa is fully decentralized and gives support for monitoring, controlling and reconfiguring fault-tolerant applications and services. It is composed of base services, a set of cooperating management agents executing on every node of the system, and a management supervisor, which implements the high-level management functions and the interface with the user. In this paper, we focus our attention on the protocol used for the mutual control of the management agents within Sampa.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Molecular mechanisms of oridonin-induced apoptosis and autophagy in murine fibrosarcoma L929 cells (2009)

Apoptosis and autophagy are genetically regulated, evolutionarily conserved processes that can jointly seal the fate of cancer cells. However, substantial gaps remain in our understanding of the molecular mechanisms that mediate the two cellular processes. In the present study, the exposure of murine fibrosarcoma L929 cells to oridonin led to the generation of intracellular reactive oxygen species (ROS) and, subsequently, the ROS triggered apoptosis by Bax translocation, cytochrome c release and ERK activations. In addition, oridonin induced autophagy in L929 cells, and the inhibition of autophagy by 3-MA or siRNA against LC3 and beclin 1 promoted oridonin-induced apoptosis. Furthermore, p38 and NFkappaB were confirmed to have roles in inhibiting apoptosis but promoting autophagy. Moreover, the inhibition of autophagy could reduce oridonin-induced activation of p38. Finally, NFkappaB activation was inhibited by blocking the p38 pathway. In conclusion, these findings indicate that oridonin-induced apoptosis can be regulated by ROS-mediated signaling pathways, and oridonin-induced autophagy may block apoptosis by upregulating p38 and NFkappaB activation.
Retention grooves for optical-fibre connectors (1977)

Optical-fibre aligning grooves with lands of fungiform cross-section cramp inserted fibres and hold them accurately in place. Such grooves have been realised by a combination of photolithographic, etching and electrodeposition techniques. Experiments have shown that linear arrays of optical fibres can be positioned to close tolerances, while the mounting operation of the fibres is facilitated. The technique requires no adhesive. Measuring results are presented, showing that the lateral misalignment of fibres between to separately fabricated connector halves is within 5% of the outside fibre diameter. That entails a geometric coupling loss within 0.4 dB with a mean loss at 0.26 dB.
The cell adhesion molecule M-cadherin is specifically expressed in developing and regenerating, but not denervated skeletal muscle (1993)

The spatiotemporal distribution of M-cadherin mRNA has been determined by in situ hybridization in the mouse embryo and in adult skeletal muscle following experimental regeneration and denervation. M-cadherin mRNA is highly tissue specific and is found only in developing skeletal muscle. In contrast, N-cadherin mRNA has a broader tissue distribution in the embryo, being found on both neural elements and skeletal and cardiac muscle. M-cadherin is expressed in the myotomes shortly after they form, along with the myogenic regulatory factor myogenin. M-cadherin is expressed in muscles derived from the myotomes and is detected in forelimb bud precursor cells at embryonic day 11.5. In the latter case M-cadherin expression appears co-ordinately with that of myogenin and cardiac alpha-actin. Shortly before birth, M-cadherin expression is down regulated. M-cadherin can, however, be re-expressed following experimental regeneration of skeletal muscle. Here M-cadherin is transiently expressed on regenerating myoblasts but not myotubes. Following muscle denervation no evidence was found for re-expression of M-cadherin under conditions where there was strong expression of the nicotinic acetylcholine receptor on myofibres. The highly specific tissue distribution and unique developmental profile distinguishes M-cadherin from other cadherins and suggests a role in cell surface events during early myogenesis.

Isolation and structural characterization of the murine tryptophan hydroxylase gene (1991)

The mouse tryptophan hydroxylase gene was isolated and its intron/exon boundaries and putative regulatory sequences identified. To isolate the gene a mouse mastocytoma cDNA clone encoding tryptophan hydroxylase was used to identify and isolate ten overlapping DNA fragments from a mouse genomic library. Restriction mapping and sequence analysis of the clones revealed that the gene contains 11 exons and covers a region of DNA of approximately 21 kb. The transcription initiation site was mapped and the major site of initiation yields an untranslated leader sequence of 124 nucleotides. A minor initiation site is located 9 nucleotides 3' of the major site. The 5' untranslated sequence is interrupted by the first intron. Analysis of the sequence upstream of the initiation site showed the presence of several putative promoter and regulatory sequences. Nine of the ten intron/exon boundaries of tryptophan hydroxylase are conserved with tyrosine hydroxylase and phenylalanine hydroxylase, further delineating the evolutionary relationship of these three genes.
Design and comparison of different Switched Reluctance Machine topologies for electric vehicle propulsion (2010)

The present paper deals with the comparative design and analysis of 3 Switched Reluctance Machine (SRM) topologies for electric vehicle propulsion. A preliminary design of the machine will be carried out, giving the initial geometric and electric (winding) data. Different numbers of phases and different combinations of stator and rotor pole numbers will be considered, keeping the same main dimensions (outer and inner stator diameter, airgap length, stack length, stator pole height, stator yoke width, rotor pole height) and the same winding per phase (number of turns and wire diameter).
Towards robot cultures? (2004)

The study of imitation and other mechanisms of social learning is an exciting area of research for all those interested in understanding the origin and the nature of animal learning in a social context . Moreover, imitation is an increasingly important research topic in Artificial Intelligence and social robotics which opens up the possibility of individualized social intelligence in robots that are part of a community, and allows us to harness not only individual learning by the single robot, but also the acquisition of new skills by observing other members of the community (robots, humans, or virtual agents). After an introduction to the main research issues in research on imitation in various fields (including psychology, biology and robotics), we motivate the particular focus of this work, namely the correspondence problem . We describe Action Learning for Imitation via Correspondences between Embodiments (Alice), an implemented generic framework for solving the correspondence problem between differently embodied robots. Alice enables a robotic agent to learn a behavioral repertoire suitable to performing a task by observing a model agent. Importantly, the model agent could possibly possess a different type of body, e.g. a different number of limbs or joints (implying different degrees of freedom), a different height, different sensors, a different basic action repertoire, etc. Previously, in a test-bed where the agents differed according to their possible movement patterns, we demonstrated that the character of imitation achieved will depend on the granularity of subgoal matching, and on the metrics used to evaluate success. In our current work, we implemented Alice in a new test-bed called Rabit where simple simulated robotic arm agents use various metrics for evaluating success according to actions, states, effects, or weighted combinations. We examine the roles of synchronization , looseness of perceptual matching , and of proprioceptive matching by a series of experiments. Also, we study how Alice copes with changes in the embodiment of the imitator during learning. Our simulation results suggest that synchronization and loose perceptual matching allow for faster acquisition of behavioral compentencies at low error rates. Social learning (broadly construed) plays a role as a replication mechanism for behaviors and results in variability when the transmitted behavior differs from the model’s behavior, thus providing the evolutionary substrate for culture and its pre-cursors. Social learning in robotics could therefore serve as the basis for culture in societies whose members include artificial agents. We address the use of imitative social learning mechanisms like Alice for transmission of skills between robots, and give first examples of transmission of a skill despite differences in embodiment of agents involved. In the particular setup, transmission occurs through a chain, as well as emerging in cyclic arrangements of robots. These simple examples demonstrate that by using social learning and imitation, (proto-)cultural transmission is possible among robots, even in heterogeneous groups of robots.
MobiGUITAR: Automated Model-Based Testing of Mobile Apps (2014)

As mobile devices become increasingly smarter and more powerful, so too must the engineering of their software. User-interface-driven system testing of these devices is gaining popularity, with each vendor releasing some automation tool. However, these tools are inappropriate for amateur programmers, an increasing portion of app developers. MobiGUITAR (Mobile GUI Testing Framework) provides automated GUI-driven testing of Android apps. It's based on observation, extraction, and abstraction of GUI widgets' run-time state. The abstraction is a scalable state machine model that, together with test coverage criteria, provides a way to automatically generate test cases. When applied to four open-source Android apps, MobiGUITAR automatically generated and executed 7,711 test cases and reported 10 new bugs. Some bugs were Android-specific, stemming from the event- and activity-driven nature of Android.
Milk fat and gastrointestinal illness. (1984)

The population of a pediatric practice was followed prospectively and determinants of acute gastrointestinal illness were evaluated in a nested age-matched case-control study. Children over age one taking low fat milk as their only milk source in the three weeks prior to illness had five times the risk of a doctor's visit for acute gastrointestinal illness as did children taking only whole milk during the same time period. This increased risk could not be explained by numerous potentially confounding variables or potential biases. There was no indication that the increased risk differed for rotavirus positive or rotavirus negative illness, or that it varied by children's age.
100 Years of Suramin (2019)

Suramin is 100 years old and is still being used to treat the first stage of acute human sleeping sickness, caused by <i>Trypanosoma brucei</i><i>rhodesiense</i> Suramin is a multifunctional molecule with a wide array of potential applications, from parasitic and viral diseases to cancer, snakebite, and autism. Suramin is also an enigmatic molecule: What are its targets? How does it get into cells in the first place? Here, we provide an overview of the many different candidate targets of suramin and discuss its modes of action and routes of cellular uptake. We reason that, once the polypharmacology of suramin is understood at the molecular level, new, more specific, and less toxic molecules can be identified for the numerous potential applications of suramin.
