Expansion Of The Retinal Fibers In The Medial Terminal Nucleus Of The Rat

In addition to optic pathways ending in the thalamic and colliculi regions, a well-defined accessory optic system has been established in a variety of mammalian species (Campbell and Hayhow, 1972; Cavalcante et a! ., 1975; Cummings and DeLahunta, 1969; Eicher and Moore, 1974; Garey and Powell, 1968; Giolli 1961; Giolli, 1963; Hayhow, 1959; Hayhow et al., 1960; Hayhow, 1966; Hendrickson et al., 1970; Hicks and D'Amato, 1970; Lin et al., 1976; Pentney and Cotter, 1976; Singleton and Peele, 1965; Thorpe and Herbert, 1976, Tigges and Tigges, 1969a,b; Cooper, 1986; Terubayshi and Fujisawa, 1984; Cooper and Magnin, 1987; Pak. et al., 1987). The components of this system are usually described be the schema proposed by Hayhow and his associates in the rat (16) and, in general, consist of two fasciculi of optic fibers and three terminal regions. The nuclear regions are a dorsal terminal nucleus (DTN) at the anterolateral edge of the superior colliculus, a lateral terminal nucleus (LTN) found ventral to the medical geniculate nucleus on the dorsolateral surface of the cerebral peduncle, and a medial terminal nucleus (MTN) found between the interpeduncular nucleus and medial aspect of the cerebral peduncle, in the rostral portion of the midbrain tegmentum. A superior fasciculus of retinal fibers leaves the optic tract at the brachium of the superior colliculus and sends projections into the DTN. In addition, this superior fasciculus courses over the medial geniculate nucleus to end in the LTN, and a few fibers in the anterior portion continue over the lateral aspect of the peduncle to terminate in the MTN. The inferior fasciculus contains retinal fibers which leave the optic tract just behind the optic chiasm and course over the superficial portion of the lateral hypothalamus to terminate in the MTN. This fasciculus does not contribute any known projections to other nuclear opponents of the accessory optic system.
Investigating the Dimensionality and Stability of Union Commitment Profiles over a 10-Year Period: A Latent Transition Analysis

The authors adopt a person-centered approach to the investigation of the dimensionality of the union commitment construct by capitalizing on a 10-year longitudinal study (from 1992 to 2002) of 637 union members in their first year of employment measured again 1 and 10 years later. Results reveal four distinct profiles of union commitment, presenting a stable structure over time. These profiles demonstrate consistency in commitment level across the three most common union commitment dimensions, thus questioning the necessity of adopting a multidimensional approach. Results show that union members became more similar to other members of their profiles over time, and that their union commitment became slightly less extreme as union tenure increased. Finally, results show that union commitment profiles predict union participation, in accordance with our expectations, and suggest that endorsing positive attitudes toward unions and their instrumentality was a stronger predictor of profile membership than was satisfaction with the actions of one’s own union.

Informed trading, flow toxicity and the impact on intraday trading factors

This study involves a detailed discussion on the estimation of intraday time-varying volume synchronised probability of informed trading (VPIN), a proxy for levels of informed trading and flow toxicity, followed by intraday analysis on its impact of the behaviour of intraday trading in a limit order book (LOB) market. The variation of VPIN used is closely based on the original from Easley, Lopez de Prado and O’Hara (2010), using trade volume imbalance information. This study shows that different capitalisation stocks exhibit different VPIN characteristics. Previous studies on other variations of PIN have looked at its determination on price movements, and whether a lead-lag relationship exists. This study examines if VPIN has an effect on several of intraday trading factors in the Australian market, being a LOB. In particular, it documents if Granger causality exists between (1) VPIN and quote imbalance, 20(2) VPIN and intraday price volatility and (3) VPIN and intraday trade frequency or similarly in an inverse manner, duration. For this analysis the Hsiao-Kang methodology for Granger testing has been followed and the posterior odds ratio test used to measure the strength of Granger causality in equity markets as suggested recently by Atukeren (2005). Feedback causality between VPIN and all three intraday factors is apparent.
Electronic and Lattice Dynamical Properties of the Iron-Based Superconductors LiFeAs and NaFeAs

The electronic structure and lattice vibrational frequencies of the newly discovered superconductors, LiFeAs and NaFeAs, are calculated within density functional theory. We show that, in the vicinity of the Fermi energy, the density of states is dominated by contributions from Fe 3d states. We also calculate the electron-phonon coupling strength and show that it is too weak to account for the observed values of the superconducting transition temperatures. This seems to indicate that the iron-based superconductors are not of the conventional type.
Extension of Risk-Based Measure of Time-Varying Prognostic Discrimination for Survival Models

The Cox proportional hazards (PH) model and time dependent PH model are the most popular survival models in survival analysis. The hazard discrimination summary HDS(t) proposed by Liang and Heagerty [2017] is used to evaluate the mean hazard difference between cases and controls at time t. Liang and Heagerty [2017] evaluated the discrimination performance under the PH model and time dependent PH model with right censoring. In this thesis, first, we further investigate their method via comprehensive simulations including 1) We extend the simulation in Liang and Heagerty [2017] under the PH model by adding more scenarios such as different distributions, censoring proportions under the PH model; and 2) similarly, more situations were added to time dependent PH model such as different time dependent functions. Second, we develop an estimation method of HDS(t) for the PH model with interval censored data. Third, we apply the proposed method to HIV data from Health Sciences South Carolina (HSSC).
What Is It About Relationships? A Behavioral Theory of Social Capital and Performance

Researchers have consistently found a positive relationship between bundles of high-performance human resource (HPHR) practices and organizational performance, but, to date, the mechanisms underlying this relationship have remained unclear. Recent work has suggested “social capital” mediates the HPHR practice–performance relationship. Building upon this work I develop and test a behavioral theory of how this occurs. Specifically, I argue that HPHR practices signal the importance of high-quality relationships, and I find, using a sample of seventy-five hospital nursing units, that HPHR practices foster higher-quality interactions and capabilities for rapid error detection and correction, which, in turn, substantially reduce the incidence of medication errors and patient falls.
SITE CHARACTERIZATION FOR EXPLOSIVES CONTAMINATION AT A MILITARY FIRING RANGE IMPACT AREA

A study was conducted at the inland firing ranges at Fort Ord to determine the current levels of explosives residues and to recommend appropriate future site characterization techniques. A set of 280 soil samples was collected from depths ranging from 0-15 cm to 105-120 cm (0-6 in to 42-48 in) from anti-tank ranges 44 and 48. Sampling locations were selected on the basis of the locations of current and former targets, and included an area away from specific targets and a background area, not affected by local detonations. HMX was the explosives residue present at the highest concentration. Much lower concentrations of RDX, TNT, and two isomers of aminodinitrotoluene were also detected. Explosives residues were largely confined to surface soils near tank targets. A major problem for site characterization was found to be the large spatial heterogeneity present. Composite samples very effectively provided representative samples for 5x5 m (200x200 in) size grids. A colorimetric on-site method gave reliable results for HMX, relative to SW846 Method 8330. No currently available on-site method for RDX was found to be adequate in the presence of much higher concentrations of HMX.
Title Modeling power in multi-functionality sensor network applications

With the migration of a Wireless Sensor Network (WSN) over various evolving applications, power estimation and profiling during the design cycle become critical issues and present hurdles in reducing the design time. Furthermore, with a growing size of the network, simulating the behavior of each sensor node is not feasible. It is important to devise an approach that provides a network-wide picture of power consumption and of variations in power usage under changes in the network and/or node application in the network. In this paper, we present a modular power estimation technique which simplifies the power modeling of any sensor network application. In particular, we are interested in analyzing the behavior of power consumption if one or more modules of the WSN platform in the application are changed during the design cycle or after the deployment. The proposed technique is susceptible to applications changes on the fly and is particularly beneficial in networks with large number of nodes. We perform experiments modifying parameters of a ZigBee based sensor network application such as packet size, sampling rate, functionality (encryption) and sensor types. We present the results, demonstrating an error less than 3% in all the experiments performed, and insights into the results.
Rapid detection of Salmonella in food and beverage samples by polymerase chain reaction

Polymerase chain reaction (PCR) assay had been used to detect Salmonella in food and beverage samples using suitable primers which are based on specific invA gene of Salmonella. Twenty nine samples were collected from street food counters and some canteens in Margonda Street, Depok, West Java, Indonesia. It was found that five of twenty nine samples were detected to contain Salmonella and showed the presence of the amplified product of the size 244 bp. The method of PCR demonstrated the specificity of invA primers for detection of Salmonella as confirmed by biochemical and serological assay. The results of this study revealed that PCR was a rapid and useful tool for detection of Salmonella in food and beverage samples.
Study Habit, Self-Concept and Science Achievement of Public and Private Junior Secondary School Students in Ogun State, Nigeria

This study compared study habit, self-concept and science achievement of students in public and private junior secondary schools in Ogun State, Nigeria. Twelve secondary schools were randomly selected from Egba and Ijebu divisions of the state. A sample of three hundred and sixty (360) students participated in the study. Three research instruments were used to collect data. There was no significant difference in study habit and selfconcept of students in public and private schools. However, private school students performed significantly better than their public school counterparts in integrated science (t = 3.400, p student study habit and self-concept combined together and singularly predicted science achievement. Counsellors should encourage students to study and also train them on how to improve their self-concept in order to improve science achievement. Key Words: Study habit, self-concept, science achievement, public and private schools, junior secondary schools.
A Time to Scatter Stones, and a Time to Gather Them: Annual Cycle in Managerial Risk Taking

Analyzing a sample of hedge funds reporting daily returns to Bloomberg, we document a strong seasonal pattern in managerial risk taking. During earlier months of a year, poorly performing funds reduce their risk. The reduction is stronger for funds with higher management fees, shorter redemption notice periods, and recently deteriorating performance, consistent with a managerial aversion to early fund liquidation. Towards the end of a year, poorly performing funds gamble for resurrection by increasing risk. The increase is strongly pronounced for funds with and without a high-water mark provision. The results are consistent with the importance of managerial outside options for optimal response to poor performance (Drechsler 2014), and can be attributed to time variation in the job-market opportunities of hedge fund managers.
Comparative Study of Commercially Available Infectious Bursal Disease Vaccine with Egg Attenuated Live Vaccine

Infectious bursal disease (IBD) is one of the most contagious viral and immunosuppressive diseases in young chickens. Vaccination at proper time is the only way to control the disease. In Pakistan, however, the development of an efficacious and economical vaccine is a major issue. The objective of the study was, therefore, to develop an effectual and inexpensive vaccine. In total, 300 birds were divided into six groups (A to F), each of 50 birds and inoculated subcutaneously on 10 th day of age. Three different passaged virus (8, 16 and 24), field isolate and commercial IBD vaccine were tested. The gross pathological and histopathological changes were recorded for bursa, thymus, muscles and kidney. The serum samples were collected for antibody titration against IBDV. Significant changes including swelling and hemorrhages started at 48 th h to 10 th day post inoculation (PI) in group receiving commercial vaccine, whereas group with inoculation schedule of 24 th passage showed very low bursal lesion with regards to the control group. Greater bursa body weight ratio was observed in the group receiving commercial vaccine compared with the one units field isolate and the one units 8 th passage, whereas it decreased in groups with 16 th and 24 th passage. The titre of virus was high in the groups with field isolates and that of 8 th passage, whereas group with commercial vaccine and 24 th passage had moderate titre with respect to other groups. Bursal changes were minimal in all groups except for group with 24 th passage, where no changes were found at 24 h PI relative control group. There were no histopathological changes in the muscles, kidney and thymus in the 24 th passage group E respect to all other groups. Greater antibody titer and highest (100%) protection against disease was observed in this group with regard to other groups. On the basis of our results, 24 th passage virus can be used to protect the birds from IBD.
Strategic Implications of Information Systems Resources and Capabilities: A Competence-Based Model

This paper examines the relationship between information systems capabilities and firm performance using resource-based theory as the theoretical lens. We identify and define three key constructs: IS resources, IS capabilities and IS competencies. We develop a research model that relates these constructs and firm performance. The basic premise of our model is that IS competencies have a direct impact on firm performance where as IS resources and capabilities are antecedents to IS competencies. Implications of this study for future research and practice are discussed.
Creating anoxic and microaerobic conditions in sequencing batch reactors treating volatile BTX compounds

An experimental strategy is introduced for studying the biodegradation of wastewaters containing volatile contaminants using an alternating anoxic/microaerobic sequencing batch reactor (SBR). Benzene, toluene, and the xylene isomers (BTX) served as model volatile contaminants for this study. The reactor was configured to overcome stripping the volatile BTX compounds into the atmosphere to provide opportunities for BTX biodegradation. Oxygen-free anoxic and microaerobic (< 0.2 mg/L dissolved oxygen) conditions were established using a novel laboratory reactor configuration. ORP was successfully used to monitor different electron acceptor conditions in the SBR. Toluene and m-xylene were amenable to anoxic (denitrifying) metabolism while benzene, o-, and p-xylene were biodegradable under microaerobic conditions. The results demonstrate that establishing microaerobic conditions in full-scale bioreactors may be an appropriate way to encourage the biodegradation of aerobically biodegradable volatile contaminants. Additionally, the laboratory reactor configuration introduced in this paper may be useful in subsequent studies involving microaerobic metabolism.

Julio C HernandezCamarena 1 Enrique O GraueHernandez Denise Loya-García Raul E Ruiz-Lozano Jorge E Valdez-García 1Tecnologico de Monterrey, Escuela de Medicina y Ciencias de la Salud, Monterrey, NL 64710, Mexico; 2Department of Cornea and Refractive Surgery, Institute of Ophthalmology Conde de Valenciana, Mexico City, Mexico Purpose: To report the visual and topographic outcomes of two pulsed-light-accelerated CXL (A-CXL) protocols at a 12-month follow-up and their correlation with the corneal stromal demarcation line (DL) depth. Patients and methods: Retrospective comparative cohort of patients with documented progressive keratoconus were included. Two epi-off pulsed-light [1s on–1s off] A-CXL protocols were compared: irradiance 30*8 and 45*5:20 (fluence 7.2 J/cm). UDVA, CDVA, spherical equivalent (SE), topographic astigmatism, Kmin, Kmax, Km, central corneal thickness (CCT), thinnest pachymetry (TCT) and endothelial cell density (ECD) were measured preoperatively and months 1, 3, 6 and 12 postoperative. Corneal DL was measured 1 month postoperatively using anterior segment optical coherence tomography. Results: Fifty eyes (27 patients): 22 eyes in group A-CXL (30*8), 28 eyes in group A-CXL (45*5:20). Mean age (years) was 19.04±4.71 and 20.32±4.57. DL depth (μm) at month 1 was 200.63±10.01 μm and 184.53±19.68 μm for group A-CXL (30*8) and group A-CXL (45*5:20), respectively (p<0.001). Significant improvement in CDVA, topographic astigmatism, Kmin, Kmax and Km was observed in both groups (no significant difference between groups) and no significant changes were observed in CCT, TCT and ECD with regard to baseline. Over 85% of the eyes in both protocols achieved stabilization or improvement in maximum K at the end of the follow-up. No significant correlations between DL and any visual or topographic outcomes were observed at 12 months. Conclusion: No correlation between DL depth and visual or topographic outcomes was observed on either protocol. Although significant improvement on CDVA, topographic astigmatism, Kmin, Kmax and Km was observed in both groups at 12 months, further research is needed to assure safety and effectiveness at stabilizing keratoconus progression.

*These authors contributed equally to this work Purpose: To develop and validate nomograms for predicting overall survival (OS) and cancer-specific survival (CSS) in patients with surgically resected intrahepatic cholangiocarcinoma (ICC). Patients and methods: The nomograms were developed using a development cohort of 947 ICC patients after surgery selected from Surveillance, Epidemiology, and End Results database, and externally validated using a training cohort of 159 patients admitted at our institution. Nomograms for OS and CSS were established based on the independent prognostic factors identified by COX regression models and Fine and Grey’s models, respectively. The performance of the nomograms was validated internally and externally by using the concordance index (c-index), and calibration plot, and compared with that of AJCC 8th edition TNM staging system by using c-index and decision curve analysis. Results: Age, T stage, M stage, lymph node ratio (LNR) level and tumor grade were independent prognostic predictors for OS in ICC patients, while T stage, M stage, LNR level and tumor grade were independent prognostic predictors for CSS. Nomogram predicting OS was with a c-index of 0.751 on internal validation and 0.725 up to external validation, while nomogram for CSS was with a c-index of 0.736 on internal validation and 0.718 up to external validation. Calibration plots exhibited that the nomograms-predicted and actual OS/ CSS probabilities were fitted well on both internal and external validation. Additionally, the nomograms exhibited superiority over AJCC 8th edition TNM staging system with higher c-indices and net benefit gains, in predicting OS and CSS in ICC patients after surgery. Conclusion: The constructed nomograms could predict OS and CSS with good performance, which could be served as an effective tool for prognostic evaluation and individual treatment strategies optimization in ICC patients after surgery in clinical practice.
Potassium spectra in the 700–7000 cm-1 domain: Transitions involving f-, g-, and h-states

Context. The infrared (IR) range is becoming increasingly important to astronomical studies of cool or dust-obscured objects, such as dwarfs, disks, or planets, and in the extended atmospheres of evolved stars. A general drawback of the IR spectral region is the much lower number of atomic lines available (relative to the visible and ultraviolet ranges). Aims. We attempt to obtain new laboratory spectra to help us identify spectral lines in the IR. This may result in the discovery of new excited atomic levels that are difficult to compute theoretically with high accuracy, hence can be determined solely from IR lines. Methods. The K vapor was formed through the ablation of the KI (potassium iodide) target by a high-repetition-rate (1.0 kHz) pulsed nanosecond ArF laser (λ = 193 nm, output energy of 15 mJ) in a vacuum (10 −2 Torr). The time-resolved emission spectrum of the neutral atomic potassium (K i) was recorded in the 700–7000 cm −1 region using the Fourier transform infrared spectroscopy technique with a resolution of 0.02 cm −1 . T hef -values calculated in the quantum-defect theory approximation are presented for the transitions involving the reported K i levels. Results. Precision laboratory measurements are presented for 38 K i lines in the infrared (including 25 lines not measured previously in the laboratory) range using time-resolved Fourier transform infrared spectroscopy. The 6g, 6h, and 7h levels of K i are observed for the first time, in addition to updated energy values of the other 23 K i levels and the f -values for the transitions involving these levels. Conclusions. The recorded wave numbers are in good agreement with the data from the available solar spectrum atlases. Nevertheless, we correct their identification for three lines (1343.699, 1548.559, and 1556.986 cm −1 ).
