Electrical oscillations induced by the metal-insulator transition in VO2

We systematically investigate the characteristics of an electrical oscillation observed in two-terminal vanadium dioxide (VO2) devices. These oscillations are observed at room temperature in a simple electrical circuit without inductive components. The circuit is composed only of a dc voltage source, the VO2 device, and a standard resistor connected in series with the device. We explain why the observed oscillations are a result of the percolative metal-to-insulator transition (MIT) of VO2 and the coexistence of the metal and insulating phases. Specifically, oscillations are attributed to the construction and destruction of capacitive regions composed of regions of the semiconducting phase, (as dielectric material) and metallic phase electron carriers, induced by the MIT (as capacitor electrodes). Since the coexistence of these phases—and thus the capacitive regions—is destroyed by elevated temperature, the MIT oscillation is not explained in terms of significant heat input but rather in terms of a voltag.
Tacit knowledge and organisational performance: construction industry perspective

Purpose - The purpose of this paper is to highlight the importance of tacit knowledge in construction and to underline the significant contribution of tacit knowledge towards the organisational performance. Design/methodology/approach - Includes a review of literature on principal insights of dominant views on knowledge and organisational resources to highlight the strategic nature of tacit knowledge. Further, intrinsic characteristics of the construction industry are discussed to underline the people factor and the role of the tacit knowledge. Findings - Valuable human and knowledge resources will be wasted unless organisations make better use of these prime resources. Tacit knowledge in particular is still considered to be relatively unexplored and proper understanding and management of this resource are of immense importance for better organisational performance. In this context, this paper reveals the labour and knowledge intensive nature of the construction industry and highlights the importance and the significant role of people factor and tacit knowledge in construction. Originality/value - Owing to paucity of literature and inadequate empirical research done, this paper provides the basis for more empirical research on finding importance of tacit knowledge towards organisational performance in the construction industry.
THE CLOSEST M-DWARF QUADRUPLE SYSTEM TO THE SUN

We report new infrared radial velocity measurements obtained with CSHELL at NASA's Infrared Telescope Facility that reveal the M3.5 dwarf GJ 867B to be a single-lined spectroscopic binary with a period of 1.795 ± 0.017 days. Its velocity semi-amplitude of 21.4 ± 0.5 km s−1 corresponds to a minimum mass of 61 ± 7 MJUP; the new companion, which we call GJ 867D, could be a brown dwarf. Stable astrometric measurements of GJ 867BD obtained with CTIO's 0.9 m telescope over the last decade exclude the presence of any massive planetary companions (7–18 MJUP) with longer orbital periods (2–10 yr) for the majority of orientations. These complementary observations are also used to determine the trigonometric distance and proper motion of GJ 867BD; the measurements are consistent with the HIPPARCOS measured values of the M2 dwarf GJ 867AC, which is itself a 4.1 day double-lined spectroscopic binary at a projected separation of 24. ″5 (216 AU) from GJ 867BD. These new measurements strengthen the case that GJ 867AC and GJ 867BD are physically associated, making the GJ 867 system one of only four quadruple systems within 10 pc of the Sun (d = 8.82 ± 0.08 pc) and the only among these with all M-dwarf (or cooler) components.
DNA Sequence Similarity between California Isolates of Cryptosporidium parvum

ABSTRACT We evaluated whether nucleic acid amplification with primers specific for Cryptosporidium parvum followed by automated DNA sequence analysis of the PCR amplicons could differentiate between California isolates of C. parvum obtained from livestock, humans, and feral pigs. Almost complete sequence identity existed among the livestock isolates and between the livestock and human isolates. DNA sequences from feral pig isolates differed from those from livestock and humans by 1.0 to 1.2%. The reference sequence obtained by Laxer et al. (M. A. Laxer, B. K. Timblin, and R. J. Patel, Am. J. Trop. Med. Hyg. 45:688–694, 1991.) differed from California isolates of C. parvum by 1.8 to 3.2%. These data suggest that DNA sequence analysis of the amplicon of Laxer et al. does not allow for differentiation between various strains of C. parvum or that our collection of isolates obtained from various hosts from across California was limited to one strain ofC. parvum.
The Validity of Self-Reported Criminal Arrest History Among Clients of a Psychiatric Probation and Parole Service

Abstract Self-report data have consistently demonstrated acceptable reliability and validity in prior studies by exhibiting high correlations with other criterion related measures of criminal frequency and arrest history. Mental health factors and substance abuse factors are suspected to affect the quality and accuracy of self-reported data. This analysis sought to examine the impact of major mental illness and substance abuse factors on the validity of self-reported criminal history data as given by clients of a psychiatric probation and parole service. After controlling for socio-de-mographic variables, the number of officially recorded arrests, high number of lifetime hospitalizations and overall years spent in jail significantly explained the number of self-reported arrests. The predominance of the official record in explaining self-reported arrest history suggests that self-reported arrest history data given by a psychiatric offender population is as valid as that given by general offender populations. Substance abuse factors and mental illness factors did not affect the quality and accuracy of self-reported arrest history.
Detection of BCL‐6 rearrangements and p53 mutations in malt‐lymphomas

Twenty‐seven lymphomas of mucosa‐associated lymphoid tissue (MALT) derived from distinct anatomical sites were tested for the presence of genetic lesions commonly involved in B‐cell lymphomagenesis, including activation of proto‐oncogenes (BCL‐1, BCL‐2, BCL‐6, and c‐MYC), disruption of tumor suppressor loci (p53, 6q), and infection by viruses [Epstein‐Barr virus (EBV), and Kaposi's sarcoma‐herpesvirus/human herpesvirus‐8 (KSHV/HHV‐8)]. Sixteen low‐grade and 11 high‐grade MALT‐lymphomas were included in the study. The presence of genetic lesions was tested by a combination of molecular approaches, including Southern blot hybridization, polymerase chain reaction (PCR), and PCR‐single strand conformation polymorphism followed by DNA direct sequencing. Alterations of BCL‐1, BCL‐2, or c‐MYC, as well as infection by KSHV/HHV‐8, scored negative in all MALT‐lymphomas analysed. Conversely, rearrangements of BCL‐6 and mutations of p53 clustered with a fraction of high‐grade MALT‐lymphomas. Deletions of 6q occurred in selected cases of both low‐ and high‐grade MALT‐lymphomas, whereas a monoclonal infection by EBV was restricted to one single patient. These data corroborate the notion that the molecular pathogenesis of MALT‐lymphomas differs substantially from that of nodal B‐cell lymphomas. Occasionally, however, a proportion of high‐grade MALT‐lymphomas may harbor selected genetic lesions among the ones commonly involved in nodal B‐cell lymphomagenesis. Am. J.

Irritability and Repellency of Synthetic Pyrethroids on an Aedes aegypti Population from Thailand

ABSTRACT: The main objective of this study was to find the optimal dosage of deltamethrin, cyphenothrin, d-tetramethrin, and tetramethrin that would elicit repellency and irritability responses of Aedes aegypti. The F1-F3 generations of field mosquitoes collected from Pu Teuy Village, Sai-Yok District, Kanchanaburi Province, Thailand, were tested with four pyrethroids to determine the LC25, LC50, and LC99. These concentrations were 0.010%, 0.020%, and 0.055%, respectively, for deltamethrin; 0.113%, 0.167%, and 0.353%, respectively, for cyphenothrin; 2.091%, 2.770%, and 5.114%, respectively, for d-tetramethrin; and 2.377%, 4.251%, and 10.715%, respectively, for tetramethrin. All dosages were tested in the excitorepellency system. Survival analysis was used to compare each chamber of the test. It was found that cyphenothrin had a stronger repellent effect than the other pyrethroids, while the contact irritant effect was similar among compounds tested. The LC50 of each pyrethroid was found to be the optimal dose for repelling Ae. aegypti. There was no significant difference in LC99 values for either non-contact or contact trials for each pyrethroid.
Carbamazepine, a possible adjunct or alternative to lithium in bipolar disorder

ABSTRACT – The effect of carbamazepine in bipolar disorder has been studied by several groups. According to these studies carbamazepine appears to exert a “lithium‐like” effect. Twelve patients with lithium‐resistant bipolar disorder and without epilepsy were prophylactically treated for 3 years with carbamazepine in an open study. In most patients carbamazepine was added to lithium, neuroleptics and/or antidepressants. Four patients did not complete the minimum treatment period of 6 months required for evaluation. In the remaining eight patients carbamazepine seemed to be effective in four patients, had a possible or slight effect in two, and no effect in the remaining two. It is concluded that carbamazepine can be safely combined with lithium, and that carbamazepine, eventually combined with lithium, can be effective in lithium(‐alone)‐resistant bipolar disorder.
Evaluating Enterprise Resource Planning Analysis Patterns using Normalized Systems Theory

— A dramatically increasing competition in business environment has brought a new characteristic of enterprise information systems called “evolvability”. Its on-going changes significantly impact the way information systems are being analysed and designed in practice. Based on Normalized Systems theory, information systems should be designed in 1-1 modular structure to be free from so-called combinatorial effects. Combinatorial effects are one of the biggest obstacles to implementing evolvability of information systems. Combinatorial effects actually occur when a change has a ripple effect on the information system size. Hence, information systems should be designed to minimize combinatorial effects in order to enhance the evolvability of software. Moreover, Normalized Systems theory provides an important practical way of developing evolvable information systems, even huge application systems for organizations. The purpose of the paper is to present an analysis of the analysis patterns of the well-known Microsoft Dynamics CRM 2016 adhering to the design patterns of Normalized Systems theory. Additionally, the paper shows the evaluation of the Enterprise Resource Planning (ERP) analysis patterns from an evolvability point of view and demonstrate both conformance with Normalized Systems theory and violations against it.
How effective are research spin-off firms in Italy?

Dans les dernieres annees une attention de plus en plus croissante s’est concentree autour du phenomene des spin-off de la recherche au niveau europeen et americain. Malgre cela, il n’y a pas d’etudes nombreuses sur le cas des spin-off de la recherche italiennes. Ce papier se propose d’examiner le contexte des entreprises spin-off de la recherche en Italie. Une particuliere attention est focalisee sur la comparaison entre un exemplaire de spin-off et un exemplaire de start-up avec le but de mettre en evidence les differences dans la performance. L’Italie est un pays interessant pour cette analyse. Les recentes initiatives autour des orientations entrepreneuriales des universites, l’attention pour ce phenomene et le nombre des entreprises spin-off italiennes en forte croissance depuis les dernieres annees, sont les premieres motivations pour le choix de ce pays : l’Italie est un des pays europeens ou une investigation generale etait vraiment necessaire et desirable.
Cytological alterations in isolated hepatocytes from common carp (Cyprinus carpio L.) exposed to microcystin‐LR

Microcystin‐LR (MC‐LR) is the most commonly encountered of the toxic cyclic peptide hepatotoxins occurring in China. It is a model compound for toxicological studies. In this study, the toxicity of MC‐LR (50 and 500 μg/L) on isolated carp hepatocytes was determined and the ultrastructural alterations of cells induced by MC‐LR were observed. The alterations noted when hepatocytes were exposed to 50 μg/L MC‐LR were blebbing of cell membrane, shrinking and deformation of nuclei, vesiculation and transformation into concentric membrane whorls of RER, and swelling and rearrangement of the cytoskeleton. However, when the cells were exposed to 500 μg/L MC‐LR, broken cell membranes, nuclei and cytoskeleton could be observed. These ultrastructural changes paralleled the pathological events, which lead to apoptosis or necrosis of hepatocytes. These results suggest that disruption of the cytoskeletal structures could account for the blebbing of cell membrane and apoptosis induced by MC‐LR. © 2001 John Wiley & Sons, Inc.

The effect of tyramine on phenolic acid and alcohol excretion in man.

Against a background of extensive animal experimentation (Kopin, 1966), the ability of tyramine to liberate noradrenaline from its binding sites has recently been investigated in man (Engelman & Sjoerdsma, 1964; Sandler & Youdim, 1968). The metabolism of tyramine itself has been well documented in the rabbit (Lemberger, Klutch & Kuntzman, 1966), but has not been studied systematically in the human. It would appear that tyramine administration gives rise to two series of metabolites, those deriving from its own degradation and those from the metabolism of other amines liberated by it. The possible implication of tyramine in the pathogenesis of a migraine variant has aroused considerable interest in this area of investigation (Sandler, Youdim, Southgate & Hanington, 1970). The availability of quantitative gas chromatographic procedures (Karoum, Ruthven & Sandler, 1968; Karoum, Anah, Ruthven & Sandler, 1969) has now enabled us to obtain further information about both series of metabolites. Urine samples were collected at intervals of 1, 3, 6, 9, 12 and 24 h after administration on different days of 5 mg tyramine intravenously and 125 mg tyramine orally, with appropriate placebo experiments, to six healthy adult male volunteers.
Effect of duodenal cannulation on abomasal emptying and secretion in the preruminant calf.

1. The effect of re‐entrant cannulation of the duodenum on digesta flow from, and secretion into, the abomasum of the preruminant calf was studied. 2. Calves fitted with abomasal cannulas and, at the same time or later, with re‐entrant duodenal cannulas were given, by abomasal infusion, test feeds containing glucose and minerals. Net volumes of secretory fluids entering the abomasum and amounts of digesta flowing to the duodenum were estimated from changes in concentrations of water soluble markers (phenol red and polyethylene glycol) in digesta samples collected from an abomasal cannula. 3. Amounts of abomasal contents, net volumes of secretory fluids and digesta flow to the duodenum for calves fitted with only an abomasal cannula did not differ significantly from those obtained for animals with abomasal and re‐entrant duodenal cannulas. 4. Collecting digesta from a re‐entrant cannula and returning it promptly to the animal did not affect net volumes of secretory fluids. Under these conditions with cannulas open to the atmosphere, rather than being connected together, the amounts of digesta entering the duodenum increased slightly but differences were not significant. 5. Weight gains of calves fitted with abomasal and duodenal cannulas were similar to those of intact animals. 6. It is concluded that in calves receiving liquid feeds duodenal re‐entrant cannulation is a suitable preparation for investigating digestive processes of the abomasum.
GeneChip® analysis after acute spinal cord injury in rat

Spinal cord injury (SCI) leads to induction and/or suppression of several genes, the interplay of which governs the neuronal death and subsequent loss of motor function. Using GeneChip®, the present study analyzed changes in the mRNA abundance at 3 and 24 h after SCI in adult rats. SCI was induced at T9 level by the New York University impactor by dropping a 10‐g weight from a height of 25 mm. Several transcription factors, immediate early genes, heat‐shock proteins, pro‐inflammatory genes were up‐regulated by 3 h, and persisted at 24 h, after SCI. On the other hand, some neurotransmitter receptors and transporters, ion channels, kinases and structural proteins were down‐regulated by 3 h, and persisted at 24 h, after SCI. Several genes that play a role in growth/differentiation, survival and neuroprotection were up‐regulated at 24 h after SCI. Using real‐time quantitative PCR, the changes observed by GeneChip® were confirmed for seven up‐regulated (interleukin‐6, heat‐shock protein‐70, heme oxygenase‐1, suppressor of cytokine signaling 2, suppressor of cytokine signaling 3, interferon regulatory factor‐1, neuropeptide Y), two down‐regulated (vesicular GABA transporter and cholecystokinin precursor) and two unchanged (Cu/Zn‐superoxide dismutase and phosphatidyl inositol‐3‐kinase) genes. The present study shows that inflammation, neurotransmitter dysfunction, increased transcription, ionic imbalance and cytoskeletal damage starts as early as 3 h after SCI. In addition to these effects, 24 h after SCI the repair and regeneration process begins in an attempt to stabilize the injured spinal cord.
Adenocarcinoma of the uterine cervix: prognostic significance of clinicopathologic parameters, flow cytometry analysis and HPV infection

Background. This study was designed to determine the possible impact of status of human papillomavirus (HPV) infection (no infection, single, multiple infections) on the survival of patients with cervical adenocarcinoma, to correlate the HPV status with other clinicopathologic parameters, and to examine clinical, histological and flow cytometric parameters as predictors of survival in cervical adenocarcinoma. Methods. The clinical data of 51 patients with adenocarcinoma of the cervix who were treated at the Department of Gynecology and Obstetrics, Zagreb University School of Medicine, from 1978 to 2004 were analysed: age at presentation, menstrual status, clinical stage, relapse, survival. Exact histologic subtype, architectural grade and nuclear grade were determined. DNA flow cytometry was performed to determine DNA ploidy and proliferative index. Polymerase chain reaction (SPF primers), followed by reverse hybridisation for genotyping, was used to determine the HPV status. Results. The status of HPV infection had no impact on patient survival, and could not be correlated with any of the analysed clinicopathologic parameters. Univariate analysis showed significant association between patient survival and clinical stage (p = 0.002) and architectural grade (p = 0.033). Multivariate analysis confirmed both parameters as significantly associated with survival. Menstrual status, nuclear grade, DNA ploidy and proliferative activity had no impact on patient survival. Conclusion. Clinical stage and architectural grade are significant predictors for survival of patients with cervical adenocarcinoma. Status of HPV infection, flow cytometric parameters, nuclear grade and menstrual status do not predict patient survival.
Intrathecal humoral immune response in HAM/TSP in relation to HLA haplotype analysis

Introduction – In HTLV‐1 associated myelopathy/tropical spastic paraparesis (HAM/TSP), we correlated human leukocyte antigen (HLA) haplotypes to the fine specificities of intrathecally synthesized IgG antibodies against HTLV‐1. Patients and methods – HLA haplotypes of HAM/TSP patients were determined by the standard NIH microcytotoxicity test and family HLA studies. IgG antibodies against HTLV‐1 synthetic peptides in paired CSF and serum were measured by enzyme immunoassay, and intrathecal synthesis of antibodies was evaluated. Results – HAM/TSP patients with particular HLA haplotypes (A24Cw7B7DR1DQ5, A2Cw7B7DR1DQ5, A24Cw‐B52DR15DQ6, A11Cw1B54DR4DQ4, and A24CwlB54DR4DQ4) showed more frequently intrathecal synthesis of antibodies against HTLV‐1 synthetic peptides, especially against HTLV‐1 env gp21 synthetic peptides. Conclusion – In HAM/TSP, a retrovirus‐induced human chronic inflammatory disease of the CNS, this is the first report to provide evidence that the intrathecal antiviral immune response is influenced by immunogenetic factors of the HLA complex.
Who's computing? Gender and race differences in young adults' decisions to pursue an information technology career.

Over the past ten years, information technology (IT) has emerged as a vitalpart of the global economy. Although IT job growth will not be as rapid asthe booming growth of the computer industry during the previous decade,as the IT sector matures and routine work is increasingly outsourced over-seas, the computer industry still offers favorable job prospects and faces ademand for qualiﬁed professionals (U.S. Department of Labor, 2004). Astechnology becomes more sophisticated and complex, these computer-basedjob prospects are especially promising for individuals with more advancedlevels of training and expertise (U.S. Department of Labor, 2004). Despite these fruitful career opportunities available in the computerﬁeld, women and minorities in the United States are vastly underrepresented
INCORPORATION OF TRITIATED NUCLEOSIDES AND AMINO ACIDS INTO LYMPHOID AND PLASMOCYTOID CELLS DURING SECONDARY RESPONSE TO TETANUS TOXOID IN MICE *

It has become evident in recent years that almost all antibody-containing cells formed within four days after secondary stimulation with soluble antigen arise from precursor cells that synthesize DNA during this period. ’ The kinetics and exact localization of this proliferative activity are not clearly ascertained.2 Renewed interest has focused on germinal-center cells as possible precursors of plasma c e k 3 There is lack of agreement as to the life cycle of germinal centers, their possible dependence on antigenic stimulation, their role in antibody synthesis, and their function in plasmocytopoiesis and/or lymphopoiesis. ‘ The present report is concerned with the incorporation of tritiated nucleosides and amino acids into lymphoid and plasmocytoid cells of a regional lymph node during the secondary response to tetanus toxoid. The findings will be correlated with changes in cellular composition and histological appearance of the node. Emphasis is placed on growth and behavior of germinal centers in relation to the secondary tetanus antitoxin response. The following basic experimental conditions were established in order to evaluate cellular and histological changes during the secondary response to the specific antigen given at a time remote from primary stimulation: Fluid tetanus toxoid (without adjuvant) was used as the test antigen since nonimmunized mice do not have detectable specific antitoxin. Antitoxin titers may be determined very precisely based on the capacity of the serum to neutralize active tetanus toxin.5 A six-month time-interval between primary and secondary antigenic stimulation was sufficient to allow the primary response to subside. The site of the second injection of antigen differed from the site of primary immunization so as to avert local remnants from the primary response usually detectable in the regional lymph node. Secondary stimulation was given via injection into the footpad because, in nonstimulated mice, the popliteal lymph nodes as the first regional lymphatic “stations” contain very few germinal centers and plasma cells.
