Isolation and Characterization of Bipotent Liver Progenitor Cells from Adult Mouse (2005)

Liver progenitor cells have drawn a great deal of attention both for their therapeutic potential and for their usefulness in exploring the molecular events surrounding liver development and regeneration. Despite the intensive studies on liver progenitors from rats, equivalent progenitor cells derived from mice are relatively rare. We used retrosine treatment followed by partial hepatectomy to elicit liver progenitors in mice. From these animals showing prominent ductular reactions, mouse-derived liver progenitor cell lines (LEPCs) were isolated by single-cell cloning. Phenotypic and lineage profiling of the LEPC clones were performed using immunochemistry, reverse transcription-polymerase chain reaction, and a dual-color system comprising the reporter EGFP under the control of the cytokeratin 19 promoter and the DsRed reporter under the control of the albumin promoter. LEPCs expressed liver progenitor cell markers. LEPCs also expressed some markers shared by bone marrow-derived hematopoietic stem cells c-Kit and Thy-1 but not CD34 and CD45. When cultured as aggregates in Matrigel, LEPCs differentiated into hepatocyte upon treatment with 50 ng/ml epithelial growth factor or differentiated into biliary lineage cells upon treatment with 20 ng/ml hepatocyte growth factor. In the presence of 2% dimethyl sulfoxide and 2% Matrigel, LEPCs acquired predominantly bile lineage phenotypes, with occasional patches of cells exhibiting hepatocyte phenotypes. Upon transplantation into CCl4-injured-liver, LEPCs engrafted into liver parenchyma and differentiated into hepatocytes. Considering the amenability of the mouse to genetic manipulation, these mouse-derived LEPCs may be useful tools as in vitro models to study molecular events in liver development and regeneration and can shed light in studying the therapy potential of liver stem cells.

Theophylline Pharmacokinetics in Black Zimbabwean Males (1990)

Theophylline pharmacokinetics were studied in 16 black Zimbabwean volunteers aged 20–41 years. Following a single intravenous dose of 5 mg/kg, four serum levels were collected over 24 h. Data were analyzed using a one-compartment open model. The correlation coefficient was 0.995 ± 0.004. The mean extrapolated peak level was 8.5 ± 0.9 mg/L. The mean half-life and volume of distribution were 10.1 ± 3.1 h and 0.55 ± 0.7 L/kg, respectively. The mean clearance was 0.62 ± 0.17 ml/kg/min. The mean weight was 7 kg less than the calculated ideal body weight. These data suggest a larger volume of distribution and longer half-life than in other reported populations. The clearance is on the low end of previously reported values. We postulate that the primary cause of the large volume is the decreased body fat and consequent increase in body water per kilogram. The slightly decreased clearance may have been partially due to the high carbohydrate, low protein diet of our subjects. The long half-life is simply a reflection of a large volume and a moderately low clearance. We suggest that standard per kilogram maintenance doses can be employed in this population. A larger loading dose of 8 mg/kg aminophylline is recommended. Finally, the lack of sustained release theophylline in Zimbabwe may not be a problem, given the longer half lives observed in this study.
Rey complex figure test under four different administration procedures (1995)

Abstract This study was undertaken to identify the relationship between the raw scores obtained on the Rey Complex Figure Test (CFT) under four different administration procedures; additionally, the effects of the administration procedures on the Recognition Trial (Meyers & Meyers, 1994) were examined. The Recognition Trial is a new instrument, developed to assess recognition of various parts of the CFT. Many authors have presented a variety of administration procedures; however, there are no studies that examine the relationship of the various administration procedures. The administration procedures used were as follows: (1) Copy, Immediate recall, 30-min recall, and Recognition Trial; (2) Copy, 3-min recall, 30-min recall, Recognition Trial; (3) Copy, Immediate recall, 3-min recall, 30-min recall, Recognition Trial; (4) Copy, 30-min recall, Recognition Trial. The results of the study indicate no significant difference in the 30-min recall score or on the Recognition Trial if an immediate/short-term recall was given; however, if no immediate/short-term recall was given, there was a difference in the 30-min recall score and the Recognition Trial. There was no significant difference in a time period from immediate to 3 min on the 30-min recall score.

Multi-Source Ensemble Learning for the Remote Prediction of Parkinson's Disease in the Presence of Source-Wise Missing Data (2018)

As the collection of mobile health data becomes pervasive, missing data can make large portions of datasets inaccessible for analysis. Missing data has shown particularly problematic for remotely diagnosing and monitoring Parkinson's disease (PD) using smartphones. This contribution presents multi-source ensemble learning, a methodology which combines dataset deconstruction with ensemble learning and enables participants with incomplete data (i.e., where not all sensor data is available) to be included in the training of machine learning models and achieves a 100% participant retention rate. We demonstrate the proposed method on a cohort of 1513 participants, 91.2% of which contributed incomplete data in tapping, gait, voice, and/or memory tests. The use of multi-source ensemble learning, alongside convolutional neural networks (CNNs) capitalizing on the amount of available data, increases PD classification accuracy from 73.1% to 82.0% as compared to traditional techniques. The increase in accuracy is found to be partly caused by the use of multi-channel CNNs and partly caused by developing models using the large cohort of participants. Furthermore, through bootstrap sampling we reveal that feature selection is better performed on a large cohort of participants with incomplete data than on a small number of participants with complete data. The proposed method is applicable to a wide range of wearable/remote monitoring datasets that suffer from missing data and contributes to improving the ability to remotely monitor PD via revealing novel methods of accounting for symptom heterogeneity.
Load Balancing vs. Locality Management in Shared-Memory Multiprocessors (1991)

A parallel application executes most efficiently when its workload is evenly distributed among the available processors, and processes are located close to their data. There is often a conflict between the goals of load balancing and locality management policies however, which many existing systems resolve in favor of load balancing. In this paper we use both experimentation and simulation to investigate the relationship between load balancing and locality management in shared-memory multiprocessors. Our experiments with applications on the BBN Butterfly multiprocessor show that although both techniques can improve application performance, locality management should be done before load balancing in many cases. Our simulations show that even in cases where there is a significant variation in the completion time of processes, or where the remote-to-local access time ratio is small, maximizing locality first and balancing load second usually results in the best performance. We conclude that the scheduler should not be oblivious to the location of data, as is the case with the popular central work queue model; instead, the location of data should be the primary factor influencing the initial assignment of processes to processors.

Information technology: opportunities for maintenance management (1999)

The information revolution and its impact on businesses, academic life and everyday life is still receiving much attention at conferences, in business publications and academic journals. This paper addresses some important opportunities created by the information technology (r)evolution for maintenance management. It also indicates how IT is already actively used in a number of normal working situations and points to possible new uses.
Surface Color Changes of Tomato and Other Solanaceous Fruit during Chilling (1991)

Chilling of mature-green (MG) tomato fruit (Lycopersicon esculentum Mill. and related species) was investigated to determine the effect of chilling stress on surface color during low-temperature storage. Color measurements were made with a tristimulus calorimeter (L, a, b values), and data were analyzed by multivariate analysis of variance and canonical variates analysis. Changes in surface color of MG fruit during chilling were not correlated overall with relative chilling sensitivity of cultivars/lines; however, within standard and cherry types, chilling-tolerant fruit changed surface color more during chilling than chilling-sensitive fruit when fruit were picked early in the season. Early harvests were less chilling-sensitive than late harvests. The number of hours below 15.6C in the 200 hours before harvest was positively correlated with postharvest chilling sensitivity. A high vs. ambient relative humidity during storage did not affect chilling-induced percent change in color. Tobacco mosaic virus resistance led to less and Verticillium albo-strum Reinke & Berthier resistance led to more chilling-induced color change. There was no effect from resistances to Fusarium oxysporum Schlechtend f. sp. lycopersici (Sacc.) W.C. Snyder & H.N. Hans, alternaria stem canker (Alternaria solani Sorauer), anthracnose [Colletotrichun coccodes (Wallr.) S.J. Hughes], root-knot nematode (Meloidogyne hapla Chitwood), Phytophthora infestans (Mont.) deBary, or Stemphylium botryosum f. sp. lycopersici Rotem, Cohen, & Wahl. Our results show harvest date had an effect on chilling-induced changes in surface-color in MG fruit.
Evolution of dilatancy and permeability in rock salt during hydrostatic compaction and triaxial deformation (2001)

Combined gas permeability and P and S wave velocity measurements were carried out on rock salt samples from the Gorleben salt dome and the Morsleben salt mine under hydrostatic and triaxial loading condions, mostly at room temperature. Permeabilities in the as‐received samples vary between 10 −16 and 2×10 −20 m 2 . The initial permeability is primarily due to decompaction induced by drilling, core retrieval and sample preparation. Hydrostatic loading gives rise to a marked decrease of permeability and a coeval significant increase of P and S wave velocities due to progressive closure of grain boundary cracks, tending to approach the in situ matrix permeability (<10 −20 m 2 ). The pore space sensitivity of P and S wave velocities is used to monitor the in situ state of the microstructure. Their reversals define the boundary in the state of stresses between dilatant and compactive domains (dilatancy boundary). Dilatancy during triaxial deformation of the compacted rock salt samples is found to evolve stress dependent in various stages. The crack initiation stress increases from ∼18 MPa differential stress at 10 MPa confining pressure to ∼30 MPa at confining pressures above ∼70 MPa. Dilatancy is due to the opening of grain boundary and (100) cleavage cracks and depends on the applied confining pressure. The orientation of the open cracks is primarily controlled by the loading geometry system (compression, extension). As a consequence, permeability increases dramatically with progressive dilatancy, followed by a period of plus/minus constant permeability during strain hardening up to 10% axial strain or even more. This suggests that the evolution of permeability is not only a function of dilatancy but also of microcrack linkage. Importantly, the anisotropic crack array within the samples causes a strong directional dependence of permeability.
Characteristics of the Dense Plasma Focus Discharge (1968)

The dense plasma focus discharge is produced in a hydromagnetic coaxial plasma accelerator. The final heating and compression of the plasma is accomplished by a partial conversion of the stored magnetic energy residing in the region behind the current sheath to plasma energy. The electrical behavior of the discharge is examined to determine the fraction of the initial energy involved in mechanical sheath motion, inductive storage in the accelerator, and Ohmic losses associated with the external and plasma discharge. Many analysis of this kind of datum show no definite correlation between the energy converted and neutron production. Presumably this arises from a lack of information as to how the collapse uses this energy and to the amount of plasma ejected from the dense plasma region during the collapse. From soft x-ray pinhole and Schlieren photographs, the collapse and the development of the dense plasma is unquestionably a two-dimensional pinch compression.

The Development of Better Photocatalysts through Composition‐ and Structure‐Engineering (2012)

Semiconductor photocatalysts that can effectively utilize solar irradiation hold great potential for harnessing renewable-energy sources, as well as for environmental protection and -remediation. Exploring advanced photocatalysts that have improved performance has been a central theme in photocatalysis research. Herein, we review the recent developments in the design- and fabrication of photocatalysts with an emphasis on composition- and structural control over multiple length scales. This Focus Review will be of value for researchers in the area of photocatalysis, in particular, in the aspects of material design that lead to the synthesis of better photocatalysts.
Enhanced 5G V2X services using sidelink device-to-device communications (2018)

In this paper, we present advances of sidelink (SL) device-to-device (D2D) communications as a key-enabling technology for 5G enhanced vehicular-to-everything (eV2X) communications. We provide an overview about the resource allocation and scheduling of different SL D2D modes under in-coverage and out-of-coverage application scenarios. Moreover, we present the scheduling for SL D2D V2X communications, which relies on semi-persistent scheduling (SPS) as proposed within the 3GPP specification. Simulations were carried out to evaluate the performance in terms of collision probability assuming different values of the key parameters such as resource reselection interval (RRI) and resource selection window. We finally discuss about the open technical challenges for ultra-reliable and low-latency communications as distilled from the 5G V2X use cases introduced in 3GPP Rel.15. A cooperative resource allocation and scheduling solution is also given, where a more detailed version is considered our future work on this topic.
ENUMERATING KAUTZ SEQUENCES (2002)

A Kautz s-ary closed sequence is a circular sequence of l s-ary digits 0; 1 : : : ; si1 such that consecutive digits are distinct and all subsequences of length q are distinct, too [3]. Kautz sequences (of the maximal length s(s i 1)qi1) can also be represented by the series Hs = fHs;qg1q =1 (s ¸ 2) of Kautz digraphs [3]. Namely, Hs;1 = Ks, where Ks is a complete s-vertex digraph without self-loops, and Hs;q+1 = i(Hs;q) = iqKs, where i is the operator transforming an arbitrary (di-)graph G into its arc-graph i(G) [8]. Under s; q ¸ 2, the number of the Kautz sequences of the maximal length s(s i 1)qi1 is proven to equal ssi2[(s i 1)!]s(si1)qi2 =(s i 1)s+qi2. The demonstration is based on our recent results concerning the characteristic polynomial and permanent of the arc-graph [8], applied herein to the Kautz digraphs. Wherever possible, the main subject is discussed in the wider context of related combinatorial problems, which first includes counting the linear Kautz sequences, whose number under the maximal length s(s i 1)qi1 + q i 1 is equal to ssi1[(s i 1)!]s(si1)qi2 =(s i 1)si1. Obtained results can be used for calculating the number of monocyclic and linear compounds, formed from s sorts of atoms, obeying the specified combinatorial restrictions. The former is equivalent to finding the number of respective necklaces with s kinds of beads.
Treatment of obsessive compulsive disorder: psychotherapies, drugs, and other somatic treatment. (1990)

Ninety percent of obsessive compulsive patients can be helped by treatment with behavior therapy and drug treatment, used sequentially or concurrently. The effectiveness of these treatments has been demonstrated in controlled clinical trials and is superior to electroconvulsive therapy and dynamic or cognitive psychotherapies for this disorder. Potent serotonin uptake inhibiting drugs, from the class of heterocyclic antidepressants, are the most effective antiobsessional medications currently available. Although these drugs usually do not induce complete remission, they can reduce obsessive compulsive symptoms by 30% to 42%. Behavior therapy combines exposure and response prevention, which the patient first learns with the therapist and then practices independently. With behavior therapy, patients confront the triggers for their anxiety and then delay, diminish, or discontinue their rituals. Reduction in symptoms with behavior therapy averages 50% or greater. Behavior therapy is usually not effective in patients who are substantially depressed, are delusional, fail to comply, or undermine therapy with covert rituals or avoidance techniques. The rare patient with very severe obsessive compulsive disorder who does not respond to behavior or drug therapy may be a candidate for psychosurgery. Modern psychosurgical procedures are quite safe and can improve symptoms in the majority of otherwise unresponsive patients.

Time delay estimation for ocean acoustic transient signal extraction in a multipath environment (2002)

Consideration is given to the problem of estimating the arrival times of overlapping or nonoverlapping ocean acoustic signals from a received signal which consists of an unknown deterministic signal along with scaled and delayed versions due to multipath propagation plus additive noise. The objective is to simultaneously determine the transmitted waveform and the arrival times. The proposed algorithm obtains approximately maximum likelihood estimates of the arrival times and the parameters which characterize the unknown signal, with much fewer computations that the direct implementation of the MLE. It is assumed that the number of the different paths is known and that the signal must belong to a parametric class of signals. The algorithm is demonstrated on a class of signals consisting of gated sinusoids.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Solar System as it really is and Curating as/in Common/s (2013)

   In this proposition of curating in/as common/s I am interested in a particular relation between curating and commons. I claim that there is a link between curating and ‘commoning’, that is the activity and process that produces the commons, and that this link is based in practice. It lays in the fact that the two employ forms of organisation, a particular kind of arrangement of social and aesthetic relations, space, time, forms of behaviour, customs, and ways in which these are governed and controlled, in other words the way in which they are held in common. When we say that something is curated the understanding is that we are dealing with a collection assembled and displayed accord- ing to a curatorial vision and under curator’s direction. Regardless if we are dealing with an übercurator with total control over exhibition, or if the curator’s role is instrumental in delivering the museum’s mission, or if indeed collaborative forms of curating or co-curating are engaged in process of curatorial production, a curator can be considered an apparatus of power, a dispositif in a Foucauldian sense. A different form of organisation is in- voked, however, when we refer to commons which are understood as a self-organised community shaping, managing and utilising resources through ‘community control’.
Schwingungen und Wellen (2004)

ZusammenfassungMechanische Schwingungen treten beim mathematischen Pendel (s.S. 15), beim physischen Pendel (s.S.48), beim linearen Oszillator (s.S.78), beim Drehpendel, in Luftsäulen (s.S.89) usw. auf. Elektrische Schwingungen können in elektrischen Schwingkreisen (s.S.263), in elektrischen Leitungsstücken (s. z.B. [PFE70]), in Hohlraumresonatoren (s.S.285) und anderen elektrisch leitenden resonanzfähigen Systemen erzeugt werden. Die mathematische Behandlung und die auftretenden Effekte sind völlig analog. Im folgenden Abschnitt wird der lineare Oszillator (linear oscillator) behandelt, wobei das Adjektiv linear eine doppelte Bedeutung hat: Die Oszillation erfolgt in einer Richtung (z-Achse) und die zugrunde liegende Differentialgleichung enthält nur lineare Terme.
