The Application of ARIMA Model to VN-INDEX Forecast
No full textThe stock market always attracts organisations and individuals because of its high capability of profit generation. Factors affecting the Vietnam market are diverse and unpredictable. Besides, the behaviour factor controls most of the market fluctuation. Therefore, the forecast of Vn Index has met with difficulties. ARIMA is a efficient and popular tool to forecast the data in time chain like Vn Index. Forecasting the ups and downs of Vn Index helps investors acquire the fluctuating trend of stocks to plan their strategies appropriately. In this paper, the author focuses on forecasting the Vn Index in the short term using ARIMA model with Box-Jenkins methods in 4 steps: identifying, estimating, testing as well as forecasting,and gives advice to investors in applying ARIMA
THE PURE ROTATIONAL SPECTRA OF VN (X ) and VO (X )
No full textAuthor Institution: Department of Chemistry, Department of Astronomy, Steward Observatory, University of Arizona, Tucson, AZ 85721The pure rotational spectra of VN (X ) and VO (X ) in their ground electronic states have been recorded in the frequency range 295-525 GHz. In each case, seven rotational transitions were measured. Fine structure and vanadium hyperfine splittings were resolved in these data. These radicals were produced by reacting gas-phase VCl with N (VN) or residual O (VO) in an AC discharge. Rotational, fine, and hyperfine constants were determined. In particular, the hyperfine constants \textit{a}, \textit{b}, and \textit{c} for VN have been established from a global fit to the spectra. The parameters obtained are in good agreement with previous studies
FOURIER TRANSFORM EMISSION SPECTROSCOPY OF NEW ELECTRONIC TRANSITIONS OF VN AND VO
No full textAuthor Institution: University of Arizona; Department of Chemistry, University of Waterloo; Department of Chemistry, University of CaliforniaThe emission spectra of VN and VO have been investigated in the region using a Fourier transform spectrometer. The spectra of both these species were observed in the same experiment from the microwave excitation of vapor in active nitrogen. Several new bands were observed and assigned to new electronic transitions of VN and VO. For VN, two new electronic transitions were observed with their 0-0 bands near and . These transitions have been assigned as the and transitions, respectively. The state of VN is the only known singlet state to date which was seen previously from the , transition near by Simard et al. [J. Mol. Spectrosc. 136,44 (1989)]. For VO, the transition near has been observed for the first time, although the and states have previously been seen by Merer et al. [J. Mol. Spectrosc. 125, 465, (1987)] from other transitions. A rotational analysis of the new bands provides valuable information on the low-lying electronic states of VN and VO

The purpose of this study was to evaluate the prospects for the use of gene expression analysis for early diagnosis on the prenatal stage. There was shown that gene expression analysis is a sensitive and highly specific method characterizing physiological adaptive processes. There was discussed the expedience of the further researches could be focused on the assessment of gene expression in the biological tissues samples obtained during invasive prenatal screening tests.

Identifying and validating recurrent structural variants affecting tumor genomes using GROM and VN
No full textStructural variants (SVs), large genomic alterations, are often responsible for tumor development. Most studies focus on single-nucleotide mutations and leave SVs aside due to the difficulties in their analysis. Here, we have utilized the result of a recent effort to sequence a cohort of patients with multiple myeloma. We used two main computational tools to locate and visualize SVs after comparing two different genomes (normal and tumor). The first one was the Genome Rearrangement OmniMapper (GROM), a variant caller with superior speed, sensitivity, and precision used to identify the variants. The second tool was the Variant Navigator (VN) to visually examine the reads and compare SVs in tumor samples with corresponding normal samples; this tool is more convenient than other popular ones as it collects multiple SVs from a single sample in a data table and allows us to efficiently go through the data. Visualization of the variants enables us to validate the type and location of mutation, and genes overlapping or near the variant. We found many common SVs present in tumor (but not normal) samples affecting a range of genes that are related to various functions, for example, increased tumor incidence, tumor growth, innate immunity and inflammation, etc. Finding these genes helps us identify the proteins involved in tumorigenesis and this analysis may further allow us to find potential drug targets.Winner: Second Place, 2023 Paul Robeson Library Undergraduate Research Award
A novel Veress needle mechanism that reduces overshooting after puncturing the abdominal wall
No full textBackground: Complications that occur in laparoscopic surgery are often associated with the initial entry into the peritoneal cavity. The literature reported incidences of Veress needle (VN) injuries of e.g. 0.31% and 0.23%. In a 2010 national survey of laparoscopic entry techniques in the Canadian General Surgical practice, 57.3% of respondents had either experienced or witnessed a serious laparoscopic entry complication like bowel perforation and vascular injury. As those complications are potentially life threatening and should be avoided at all costs, improving safety of this initial action is paramount. Methods: Based on a bare minimum design approach with focus on function expansion of existing components, a new Safety mechanism was developed for the VN that decreases the risks of VN overshooting. The mechanism works by preventing the puncturing acceleration of the tip of the VN by decoupling the surgeon’s hand from the VN immediately after entering the abdomen. Results: Based on a set of requirements, a first prototype of the VN+ with force decoupling safety mechanism is presented and evaluated on an ex vivo porcine abdominal wall tissue model in a custom setup. The experiments conducted by two novices and one experienced surgeon indicated a significant difference between the attempts with a standard, conventional working VN (41.4 mm [37.5–45 mm]) and VN+ with decoupling mechanism (20.8 mm [17.5–22.5 mm]) of p < 0.001. Conclusion: A new decoupling safety mechanism was integrated successfully in a standard VN resulting in a VN+. The results from the pilot study indicate that this new VN+ reduces overshooting with a minimum of 50% in a standardised ex vivo setting on fresh porcine abdominal wall specimens.</p
Pre-clinical evaluation of the new veress needle+ mechanism on thiel-embalmed bodies: a controlled crossover study – Experimental
No full textBackground: Veress needles (VN) are commonly used in establishing pneumoperitoneum in laparoscopic surgery. Previously, a VN with a new safety mechanism ‘VeressPLUS’ needle (VN+) was developed to reduce the amount of overshoot.Methods: Eighteen participants (novices, intermediates, and experts) performed in total of 248 insertions in a systematic way on Thiel-embalmed bodies with wide and small bore versions of the conventional VN (VNc) and the VN+. Insertion depth was measured by recording the graduations on the needle under direct laparoscopic vision.Results: Participants graded the bodies and the procedures as lifelike. Overall, a significant reduction (P<0.001) in average insertion depth was found for the VN+ compared to the VNc of 26.0 SD16 mm versus 46.2 SD15 mm. The insertion depth difference in the novice group was higher compared to the intermediates and experts (P<0.001). The average insertion depth for both needle types was less (P<0.001) for female participants compared to male.Conclusion: This study indicated that the VN+ significantly reduced the insertion depth in all tested conditions. Whether the difference between female and male performance can be linked to differences in muscle control or arm mass should be further investigated. Useful technical information was gathered from this study to further improve the VN+.<br/
