Abstract Invariably, the situation arises where it is desirable to transfer data from one computer to another, especially from small laboratory systems, word processors, or home computers to large mainframe computers. In many of these cases, there are no common storage media; home computers do not have 9-track tape drives and large mainframes do not have 5¼ in. floppy disk drives. Transmission of data through the telephone network is a viable method for data transfer, which is paradoxically both easier than many believe and more difficult than some may claim. One of the keys to successful data transmission is an understanding of telecommunications protocols, i.e., the rules governing intersystem communication through the telephone network. Some of the most common protocols allow exchanging ASCII-coded data at either 300 or 1200 baud. A variety of computer systems can be used, including IBM and DEC mainframes, a Wang word processor, an IBM PC-compatible microcomputer, and the Atari 800 microcomputer. A specific example is the use of the Atari 800 as an APL terminal, complete with the custom character set, standard ASCII text, and data transfer.

The High Order Method Modeling Environment is a scalable, spectral-element-based prototype for the Community Atmospheric Model component of the Community Climate System Model. The 3D moist primitive equations are solved on the cubed sphere with a hybrid pressure η vertical coordinate using an Emanuel convective parametrization for moist processes. Semi-implicit time integration, based on a preconditioned conjugate gradient solver, circumvents the time step restrictions associated with gravity waves. Benchmarks for two standard tests problems at 10 km horizontal resolution have been run on Blue Gene/L. Results obtained on a 32-rack Blue Gene/L system (65,536 processors, 183.5-teraflop peak) show sustained performance of 8.0 teraflops on 32,768 processors for the moist Held–Suarez test problem in coprocessor mode and 11.3 teraflops on 32,768 processors for the aquaplanet test problem, running in virtual node mode.

A computer program (EEG Analysis) was developed for the preclinical laboratory course in physiology held for medical and dental students. It offers an off-line analysis of a set of typical and frequently occurring physiological and pathological electroencephalogram (EEG) and evoked potential (EP) recordings, which are stored in an IBM-compatible personal computer (PC) system. The users are requested to measure and analyze the data sets and to work through a base of questions relevant in the frame of the particular topic. The program is structured in several exercises: calibration, pickup of non-EEG signals (eye movements, chewing), waveforms in EEG recordings from awake subjects (alpha-waves, beta-waves), desynchronization of cerebral activity (visual activation, acoustic activation, mental activation), habituation of cerebral activity upon acoustic stimuli, EEG recordings from asleep subjects (different sleep stages, sleep-specific EEG signals), epileptic seizures, and EPs (principle of averaging, visually evoked potentials in different cortical areas). The program runs under MS-DOS and is network capable. The software structure ensures maximal flexibility for rapid changes and adaptations of the program to specific needs of a particular EEG course. The program has been used for three years, and the response from > 800 students has been consistently positive.

The implementation of step-scanning to a research-grade FT-IR spectrometer (Nicolet system 800) is described. This implementation relies on the complete computer control of the retardation, representing a substantial improvement over results from the previous generation of step-scan spectrometers (IBM IR44) available in our laboratory. Specifically, the instrument represents an improvement in speed, stability, and attainable limit of detection. The most distinctive capability of this instrument is that of high-amplitude phase modulation (tested up to 10 ΛHeNe peak to peak) at relatively high phase modulation frequency while maintaining high position certainty. Alternatively, the phase modulation can be turned off completely and the retardation can be maintained within ±1 nm for indefinite periods between steps. The step-scan option for this instrument, along with its continuous-scan “TRS” (stroboscopic) mode, gives it a unique combination of capabilities for dynamic vibrational spectroscopy. The performance of the instrument in the step-scan mode is demonstrated with photoacoustic spectroscopy (PAS).

BACKGROUND: Reverse transcriptase-polymerase chain reaction (RT-PCR) is the primary diagnostic tool to confirm coronavirus disease 2019 (COVID-2019) due to its high specificity. However, it has relatively low sensitivity and time consuming. In contrast, chest computed tomography (CT) has high sensitivity and achieves quick results. It may, therefore, play a critical role in screening and diagnosing COVID-19. A cross-sectional study was done in 212 patients with confirmed cases and patients under surveillance for COVID-19 tested for RT-PCR and chest CT scan. Statistical analysis was performed using SPSS Version 23 (Statistical Package for the Social Sciences, IBM Corp., Armonk, NY, USA). AIM: We aim to investigate the diagnostic value of chest CT in correlation to RT-PCR in Indonesia. METHODS: A cross-sectional study was done in 212 patients with confirmed cases and patients under surveillance for COVID-19 tested for RT-PCR and chest CT scan. Statistical analysis was performed using SPSS Version 23 (Statistical Package for the Social Sciences, IBM Corp., Armonk, NY, USA). RESULTS: From a total of 212 patients, 92% of them were diagnosed as confirmed cases of COVID-19. It was found that the sensitivity of CT scan for COVID-19 patients was 72.3% (65.5% and 78.5%) with positive predictive value (PPV) of 93.9% (90.9% and 96.0%) and the sensitivity and PPV improve in symptomatic patients. Typical chest CT scan lesions were 8.0 times which were more likely (3.9–16.4; p <0.001) to be detected in symptomatic patients while patients with severe CT scan findings were 4.4 times more likely (3.0–6.5; p <0.001) to be admitted to the intensive care unit. CONCLUSION: A high PPV suggests that a chest CT scan can detect COVID-19 lesions, but the absence of the lesions would not exclude the disease’s presence.

Objective To investigate the existence and suitability of mathematical proportions between the widths of maxillary anterior teeth in Bangladeshi population having an esthetic smile, with the aid of digital photographs and computer analysis. Place of Study The study was conducted at the Department of Orthodontics and Dentofacial Orthopedics of Dhaka Dental College and Hospital, Dhaka. Period of Study The study was conducted from April 2016 to September 2016. Sample Selection The study samples collected from Students of Dhaka Dental College, Mirpur-14, Dhaka, Bangladesh, with age limit 18–35 years. Materials and Methods Standardized frontal images of 100 dental students of Dhaka Dental College were captured. All the images were downloaded to a personal computer, and width of each tooth was measured by the scale tool of Photoshop CS version 8.0. All the data were analyzed (through standard statistical method) using Statistical Package for Social Science Software version 20 (IBM Corp., USA). Results The golden proportion existed in 17% of the perceived width ratios of lateral incisor to central incisor and 4% of the width ratios of canine to lateral incisor in natural dentition. Sixty-six percent lateral incisors are following the golden percentage, but only 7% central incisors and 21% canines are following the golden percentage. The recurring esthetic dental (RED) proportion existed in only 4% of participants. Conclusions The golden proportion, golden percentage, and the RED proportion cannot be used as constant proportions to create a harmonious proportion throughout the width of maxillary anterior teeth. The adjusted golden percentage might serve as a guideline to create harmonious proportions in maxillary anterior teeth for Bangladeshi population.

There is a highly significant relationship between semen quality and the percentage of fertilized ova and transferable embryos in superovulated donors (Stroud B and Hasler JF 2006 Theriogenology 65, 65-76). Computer-assisted sperm analysis (CASA) provides an objective and highly repeatable system for sperm analysis. It has been observed that linearity (LIN) measured by CASA has a high correlation with fertility (Foote RH et al. 1998 Theriogenology 49, 871-879). In the present report, retrospective analysis was done to determine the effect of sperm linearity as assessed by CASA on the number of ova and viable embryos recovered from superstimulated cows. This research was carried out using different breeds of donors (n = 150, 80% Angus) during the last 5 years in an embryo transfer center in Buenos Aires province, Argentina. Donors with a CL received an intravaginal progesterone device (DIB®, Syntex, Buenos Aires, Argentina), 2 mg of 17? estradiol, and 50 mg of progesterone (Rio de Janeiro, Brazil), i.m. on the same day. On Day 4 after DIB® insertion, superstimulatory treatment was initiated as a decreasing dose regimen of FSH i.m. (Pluset®, Callier, Spain, or Folltropin®, Bioniche Animal Health, Inc., Belleville, Ontario, Canada) every 12 h during 4 days. On Day 6, DIB® devices were removed and cows were administered cloprostenol (2 mL) twice at 12-h intervals. When estrus was detected, donors received GnRH (2 mL i.m. Dalmarelin®, Von Franken, Buenos Aires, Argentina) and were inseminated 12 and 24 h thereafter. Semen was thawed in a water bath at 37°C for 1 min. Before insemination, every semen dose was evaluated for motility characteristics using the IVOS Sperm Analyzer (Hamilton Thorne Biosciences, Beverly, MA, USA). Two chambers of 20-(im depth and 5 fields per chamber were analyzed (30 frames/0.5 s for each field). According to CASA results, 3 groups were defined based on LIN: Group 1 = <50%; Group 2 =≥50% and <60%; and Group 3 =≥60%. Seven days later, embryo collection was performed and ovarian response was evaluated by transrectal ultrasonography to assess number of CL + anovulatory follicles. Ova/embryos were evaluated and classified according to the IETS manual. Kruskal-Wallis test was used to compare variables among groups, and results are shown in Table 1. There was a significant difference between Groups 1 and 3 for total number and percentage of viable embryos. More embryos were recovered from donors inseminated with higher LIN semen. Also, there was a significant difference between Group 1 and both Groups 2 and 3 in the number of total fertilized ova, percentage of fertilized ova, and percentage of unfertilized ova. The present results suggest that insemination of donors with semen of high LIN results in higher fertilization rates and number of viable embryos.

The urgency of the problem is due to the need to find the ratio of traditional and distance learning during the organization of full-time and part-time education. The purpose of the article is to study the views of bachelor and master students, PhD students, high school teachers on the organization of full-time and part-time education in the context of traditional (classroom, face-to-face), blended and distance learning in a classical university. Research methods: theoretical - in order to review scientific papers, formulating the conclusions of the study, etc. (analysis and synthesis, comparison, generalization, etc.); empirical - developing questions and conducting online surveys, pedagogical observation; mathematical - to process the results using the computer program IBM SPSS Statistics 23. The results of the study: we conducted an online survey of 1373 respondents in 2020 and 443 - in 2021. Online survey shows that respondents (in %, respectively bachelor and master students, PhD students, high school teachers) choose the following models of learning organization: full-time education - traditional (classroom, face-to-face) 24,8-29,3%, 12,9%, 20,3%; distance 4,9-7,9%, 2,1%, 0,6%; blended – 62,8-70,3%, 85,0%, 79,1%; part-time education: traditional (classroom, face-to-face) – 8,0-9,0%, 1,4%, 5,6%; distance – 12,4-18,5%; 10,0%, 4,3%; blended – 72,5-79,6%, 88,6%, 90,1%. Bachelor and master students of the same year of the survey express similar views on the choice of learning model for both full-time and part-time education. At the same time, a comparison of most other groups of respondents shows a statistically significant difference (p≤0,05) in such views. Respondents suggest more use of blended and distance learning in all cases, for part-time compared to full-time education.

Abstract Introduction : Malignancies are the second most common cause of death after cardiovascular diseases in patients with inflammatory bowel disease (IBD). Indeed, patients with IBD have an increased risk for developing a variety of extraintestinal malignancies, in particular, lymphomas and mostly non-Hodgkin lymphomas. In the spectrum of lymphoproliferative disorders, Hodgkin lymphoma-type is rare, only a few cases with Hodgkin's lymphoma (HL) in IBD patients have so far been reported. We report two new cases. Case 1 : A 44 year old male presented in 2010 with a history of abdominal pain, intermittent diarrhea, and rectal bleeding. The clinical, endoscopic, and pathologic findings were consistent with ulcerative colitis. Initial medical treatment was Azathioprine (50 mg, three times a day), Prednisolone (50 mg, one time a day), and 5-aminosalicylic acid (800 mg, three times a day). He was also diagnosed as having type 2 diabetes, treated with insulin. The patient was continually treated with Azathioprine through 5 years, with reduced dose (100 mg/d) because of hematological toxicity. In 2016, the patient was readmitted with severe pneumonia. He reported having abdominal pain, weight loss, night sweat, and intermittent fever for three to four months before admission. A computed tomography was performed, showed retroperitoneal, peri-aortic and iliac bilateral lymphadenopathy. Needle biopsy was performed out and histology revealed large cells of Hodgkin's type, and intense staining for CD30 and CD15 all in favor of the diagnosis of HL. Case 2 : The second patient is a 30-year-old man with ileocecal Crohn disease diagnosed at age 23 years. Remission was induced with corticosteroids and maintained by Azathioprine (150 mg/d). Three month before his admission to our unit, he complains from intermittent fever, decline in general condition. Cervical and axillary lymphadenopathy were noted. The lymph node biopsy revealed mixed-cellularity Hodgkin lymphoma. Computed tomography scan revealed stade IIIB disease for both patients. They received 6 cycles of adriamycin, bleomycin, vincristine, and dacarbazine. A complete regression of lymphadenopathy was confirmed by CT and positron emission tomography scan. Presently, the patients remain in remission and without any signs of lymphoproliferative disorder or IBD (on sulfasalazine). Discussion : IBD patients show a trend toward higher risks of developing hematological malignancies. Compared with the general population, there is an increased risk for lymphoma, especially non-Hodgkin lymphoma, with a standardized incidence rate of 1.42 (95% CI, 1.16-1.73). HL is a known rare comorbidity that can emerge in IBD patients. Thiopurines were shown to increase the incidence of lymphoma after kidney transplantation and similar observations have been reported in patients with IBD. In observational cohort, the risk of acquiring lymphomas was significantly higher (4- to 5- fold) in patients with thiopurine exposure; this risk appears to rise with longer duration of therapy and to decrease after drug withdrawal. Most of the thiopurine promoted lymphomas are attributed to the cytotoxic effects of thiopurines on EBV-specific immune cells that prevent the proliferation of EBV-infected B lymphocytes. IBD itself may contribute to the development of lymphoproliferative disorders, particularly primary intestinal HL. Indeed, recent population-based study showed an association between lymphomas and IBD, regardless of the use of thiopurines. In fact, inflammation itself plays a role in lymphomagenesis. Local sites of inflammation may be particularly at risk of lymphoproliferation, due to chronic B-cell stimulation, may also explain the frequency of gastrointestinal lymphoproliferative disorders involving the gastrointestinal tract (26% of cases). The duration of the disease appears also as an independent risk factor for lymphoma. Conclusion : HL can emerge in IBD patients on immunosuppressive therapy and physicians must be aware of this possibility. EBV infection might have an intermediate role between immunosuppressive treatment and lymphoma. Those data should alert clinicians that, not only thiopurine use but also the disease itself could contribute to a higher occurrence of lymphoproliferative disorders. Disclosures No relevant conflicts of interest to declare.

Abstract Established in 1975, Microsoft became the largest company in the world specializing in computer software, and had nearly 40,000 employees and annual revenues of almost $23 billion by 2000 (Table 5.1). Microsoft grew by skilfully moving from one software mass market to another. The company started by selling programming languages for a new personal computer (PC) kit, and then built an operating system (MS-DOS) first for IBM and then other computer equipment manufacturers. It gradually entered a variety of applications markets and sold products directly to retail stores. Microsoft eventually dominated various PC software markets throughout the world, and had a market share of around 90 per cent in operating systems (Windows and Windows NT), which provided the company with an enormous revenue stream. Microsoft also learned how to develop applications programs, and by 2000 was building more than 200 software products. In addition, the company had an Internet portal business and was rapidly increasing its presence in the Internet software (browser and server) markets, which it entered late, but by 2000 had a market share of approximately 80 per cent in browsers.

The IBM System/390 :sup.*:esup. family of mainframe computers is among the first in the computer industry to use fiber optic I/ O channels for high speed data transfer. Known as ESCON (Enterprise Systems Connection) :sup.*:esup channels, these optical links provide significantly higher bandwidth, data rates, and distance than the parallel electrical cables which they replace. The ESCON :sup.*:esup. channels consist of 200 Megabit/s duplex fiber optic links (17 Megabytes/s). Multimode links using 1300 nm LED transmitters and PIN photodiode receivers allow a maximum unrepeated distance of 3 km using 62.5 micron core fiber and 2 km using 50 micron core fiber with a minimum modal bandtvidth of 800 Mhz-km. A single-mode version using InGaAsP laser diodes increases the unrepeated distance to 20 km while maintaining international class 1 laser safety. This paper describes the optical, electrical, and mechanical design innovations of the ESCON :sup.*:esup. channels. Optical link budget modeling will be discussed, as well as design of a duplex optical connector and cable strain relief system. Experimental data will be presented on link performance in harsh environments such as elevated levels of ionizing (gamma) radiation, or customized link designs which can extend the maximum unrepeated distance.

Integrated semiconductor ring lasers with an output waveguide have been produced.1 They have attracted considerable attention because high-quality mirrors are not needed, the output termination has little influence on oscillation conditions, and the small dimensions make the longitudinal mode spacing increase so that single-mode operation is possible. A rib waveguide configuration was used to maximize light confinement and to minimize bending loss in the small cavity (Fig. 1). However, the temperature increases within the ring-laser structure are expected to be excessive as the heat source is more concentrated and the heat generated is difficult to dissipate because of the extremely small dimensions. A thermal model of the ring-laser device has been developed. Laser-device substrate and lasing rib were considered separately in this cylindrical symmetry model. For simplicity, no convection or radiation has been taken into account, and all the heat was assumed to transfer to the heat sink, which is forced down to an adjustable temperature, e.g., 20°C. The temperature distribution within the ring-laser structure has been calculated by using a finite-difference technique2 and plotted by using a Ghost 80 computer plot package (Fig. 2). The thermal resistance for the whole laser device has also been calculated (Fig. 3). All modeling was done on an IBM 3090 computer with a vector facility. The resulting temperature profiles agree with IR imaging thermal measurement results fairly well.3 The temperature gradient is strongest just beneath the rib, and the distribution is the same for an increase in input power or in heat-sink temperature. Only the temperature corresponding to each isotherm increases.

In a prospective clinical trial, we have compared the effectiveness of the computerized electroacupuncture (CEAP) added to thestandard pharmacological therapy of the patients with painful form of irritable bowel syndrome (IBS)in the main group against its isolated pharmacological therapy in the control group. The study involved 80 volunteerswhich were previously randomly divided to the 2 equal groups due to the type of treatment. Patients in the main group received three courses of CEAP. Each CEAP course contained the five everyday sessions, the interruption period between courses was one month. The inclusion of CEAP to the complex therapy of the painful IBS was accompanied with decreasingof the pain severity to 42%, byVisual Pain Scale. The patients' subjective condition indicators were significantly improved: the levels of depression (according to the Zung test), actual and personal anxiety (according to the Spiberger-Khanin questionnaire) were decreased, the parameters assessed using the SAN questionnaire were increased.

Abstract Based on graph representation of planar linkages, a new algorithm was developed to identify the different dyads of a mechanism. A dyad or class II group, is composed of two binary links connected by either a revolute (1) or a slider (0) pair with provision for attachment to other links by lower pair connectors located at the end of each link. There are five types of dyads: the D111, D101, D011, D001, and D010. The dyad analysis of a mechanism is predicated on the ability to construct the system from one or more of the five binary structure groups or class II groups. If the mechanism is complicated and several dyads are involved, the task of identifying these dyads by inspection could be difficult and time consuming for the user. This algorithm allows a complete automation of this task. This algorithm is based on the Dijkstra’s algorithm, for finding the shortest path in a graph, and it is used to develop a computer program, called KAMEL: Kinematic Analysis of MEchanical Linkages, and implemented on an IBM-PC PS/2 model 80. When compared to algorithmic methods, like the Newton-Raphson, the dyad method proved to be a very efficient one and requires as little as one tenth of the time needed by the method using Newton-Raphson algorithm. Moreover, the dyad method yields the exact solution of the position analysis and no initial estimates are needed to start the analysis. This method is also insensitive to the value of the step-size crank rotation, therefore, allowing a very accurate and fast solution of the mechanism at any position of the input link.

This research study of the validity and reliability of the Duolingo English Test was independently conducted from February-April of 2014. The study lasted for approximately eight weeks. Participants were recruited from Duolingo users who studied English, international students in several United States universities, and people who took Test of English as Foreign Language (TOEFL) at several TOEFL centers in China. Participants were at least 18 years of age and had taken the TOEFL within the last 18 months. Participants filled out a survey in the beginning of the study to provide information of their demographics such as age, gender, native language, and education background, experience in learning English, and most importantly, the date and location of taking the TOEFL iBT as well al their TOEFL scores. The participants were directed to complete the Duolingo English Test at the end of the survey. Two weeks later, the participants were instructed via email to fill out a second survey and the Duolingo English Test for the second time. Main results: • Participants’ scores on the Duolingo English Test correlated substantially with their TOEFL total scores, and moderately with TOEFL section scores, with higher correlations for the TOEFL Speaking and Writing sections. This provides criterionrelated evidence of validity of the Duolingo test scores. • Participants’ scores on the first Duolingo English Test correlated highly with their scores on a second test two weeks later, indicating that Duolingo test scores are reliable with a good test-retest reliability coefficient. • Duolingo English Test scores were linked with TOEFL total scores to find the comparable scores from the two tests that have similar percentile rank. Duolingo English Test scores are on a scale of 0–100 and TOEFL scores are on a scale of 0–120. For international students to apply for studying in US universities, the minimum cut-off score of TOEFL iBT is 80 and a more selective cut-off score is 100, corresponding to scores 50 and 72 respectively on the Duolingo English Test.
