Bovine anemia due to Theileria orientalis group (BATOG) is a tick-borne disease (TBD) affecting cattle, with Haemaphysalis spp. as the major tick involved in disease transmission [1]. Unlike the lymphoproliferative Theileria species, BATOG mainly affects the erythrocytes (RBC) and RBC-associated parameters [2]. Clinical signs include weakness, abortion, fever, pallor, and elevated respiratory and heart rates [2]. However, few clinical cases of T. orientalis infection in cattle have been reported. Consequently, T. orientalis was historically considered to cause benign infection only [2]. Despite the minimal pathogenic effects of BATOG to the cattle, significant losses have been associated due to increased treatment costs, and reduced body weight, production, and reproductive performance, and ultimately, poor welfare and death [2]. BATOG is also known as ‘oriental theileriosis’ because the main vector, Asian long-horned tick, was previously thought to be endemic in East-Asian countries only. But in the past decade, outbreaks of BATOG have been reported in many countries, including several Asian and Asia-Pacific countries [2], and recently the United States [3]. T. orientalis is categorized onto 11 genotypes, with Chitose and Ikeda as genotypes that could lead to reduced health status in cattle [4]. In South Korea, above 95% of cattle farm are operating under non-grazed management. It is favorable for the dairy farmers as it can control outdoor conditions, reduce tick exposure, and enhance the milk yield volume and composition. In South Korea, the most studied bovine TBD was BATOG, as previous reports revealed that it has the highest prevalence compared to anaplasmosis, rickettsiosis, This study reports the detection and genotyping of the first clinical case of bovine anemia due to Theileria orientalis group (BATOG) in non-grazed dairy cow in upper South Korea. Blood and serum tests revealed anemia and hyperbilirubinemia from animal showing clinical symptoms, and later confirmed as piroplasmosis-positive. Follow-up surveillance on the herd revealed 2 asymptomatic cows with anemia. The three animals were confirmed theileriosis-positive and genotyping revealed the clinical and one of the asymptomatic cases have Chitose, while the other has Ikeda genotype. Clinical BATOG cases were rarely reported worldwide, and asymptomatic animals left untreated could serve as parasite reservoir.
Generic military simulation of a complex workplace. A new tool for applied research in military settings

ABSTRACT In almost any military occupational specialty soldiers must monitor and react to stimuli, store and process information, make and communicate decisions, while using different in- and output modalities. When assessing influences on performance, e.g., by sleep-deprivation or heat-stress in intervention designs, researchers face a dilemma: They can either examine highly trained military experts in their jobs, thus risking limited generalizability of their results, or use standard measures of cognitive performance with little ecological relevance. To solve this dilemma, we developed a multidimensional job simulation by abstracting a wide range of military jobs into a generic military simulation of a complex workplace (GEMS COW). It had to meet the following requirements: 1) validly and reliably measure the relevant psychological constructs of the abstracted jobs, 2) require only minimal training, and 3) score high acceptance with military specialists. GEMS COW assesses attention, short-term memory (sm), and working memory (wm) in a lifelike setting. Three studies were conducted focusing on psychometric properties (Study 1, N = 74), overall task complexity in an intervention design (Study 2, N = 54), and acceptance (Study 3, N = 22) of GEMS COW. Psychometric properties proved satisfactory (construct validities: wm = .58, attention = .45, sm =.68; retest reliability: .61-.90). The simulation has a medium to high mental difficulty and soldiers accept it as a realistic military task. GEMS COW is easy to learn and reliably measures psychological constructs in a complex generic simulation. It can be used in intervention studies and may easily be implemented in other languages.
Development of a situational judgment test to supplement current US air force measures of officership

ABSTRACT Aptitude requirements for US Air Force officer commissioning include completion of a college degree and minimum scores on the Air Force Officer Qualifying Test (AFOQT) Verbal and Quantitative composites. Although the AFOQT has demonstrated predictive validity for officer training, the Air Force has striven to improve predictive validity and diversity. To this end, a Situational judgment Test (SJT) was added to the AFOQT in 2015. SJT development was consistent with recommendations to broaden the competencies assessed by the AFOQT with the goal of providing incremental validity, while reducing adverse impact for historically underrepresented groups. To ensure content validity and realism, SJT development was based on competencies identified in a large-scale analysis of officership and input from junior officers in scenario and response generation and scoring. Psychometric evaluations have affirmed its potential benefits for inclusion on the AFOQT. An initial study showed the SJT to be perceived as highly face valid regardless of whether it was presented as a paper-and-pencil test (with narrative or scripted scenarios) or in a video-based format. Preliminary studies demonstrated criterion-related validity within small USAF samples, and a larger Army cadet sample. Additionally, operational administration of the SJT since 2015 has demonstrated its potential for improving diversity (i.e., reduced adverse impact relative to the AFOQT Verbal and Quantitative composites). Predictive validation studies with larger Air Force officer accession samples are ongoing to assess the incremental validity of the SJT beyond current AFOQT composites for predicting important outcomes across accession sources.
Analysis of Airbreathing Hall-Effect Thrusters

The principle idea of using airbreathing electrical propulsion for a vehicle flying at orbital speed on the edge of Earth’s atmosphere is examined. In this paper, a simple model of a Hall-effect thruster in which the propellant is an ambient air is presented. A new mode of the airbreathing thruster operation is presented in which incoming air is fully ionizedwithout preliminary compression. The required lengths of the thruster chamber, themagneticfields, the thrust, and other parameters of an ideal airbreathing Hall-effect thruster are calculated as a function of the flying altitude of the vehicle. For instance, in the case of the 95-kmorbit, the lengths of thruster chamber of 47.8 cm, theHall thruster gap of 2.3 cm, and the applied voltage of 3 kV, themodel gives the thrust of about 9.1 N and the power range of about 700–800 kW depending of the strength of a magnetic field. The thruster might be powered using electromagnetic beams generated at ground power stations or crafts flying at higher orbital altitudes where the drag force is negligible. The estimates presented show that the beam receiver size will not exceed the size of the vehicle and should not generate a drag force larger than the calculated thrust.
HVDC transmission systems using voltage sourced converters design and applications

Rapid development in the field of power electronic devices with turn off capability like insulated gate bipolar transistors (IGBT) and gate turn-off thyristors (GTO), makes the voltage sourced converters (VSC) more and more attractive for high voltage direct current transmission (HVDC). This new innovative technology provides substantial technical and economical advantages for different applications compared to conventional HVDC transmission systems based on thyristor technology. This paper focuses on VSC application for HVDC systems of high power ratings (up to 200 MW), which are currently in discussion for several projects. After a brief description of the main circuit components an overview on basic design aspects of VSC based HVDC systems is given.
Design of a low-supply-voltage high-efficiency class-E voltage-controlled MMIC oscillator at C-band

In this paper, a monolithically integrated voltage-controlled class-E tuned oscillator for C-band has been designed and measured. Large-signal optimization was performed using analytically calculated starting values to reach high efficiencies at ultra-low supply voltages down to 0.9 V. The range of the tuning voltage is from 0 to the supply voltage. With a supply voltage of 1.8 V, an output power of 6.5 dBm, an efficiency of 43%, and a tuning range of 150 MHz is achieved at a center frequency of 4.4 GHz. With a supply voltage of only 0.9 V, the efficiency is 36%, with an output power of 1.1 dBm,and a tuning range of 80 MHz at a frequency of 3.6 GHz. Chip size is less than 1 mm/sup 2/.

Developing social skills and self-satisfaction of adults with intellectual disabilities through sports: a parental perspective

The purpose of the study was to investigate the effects of sports activities on social skills and self-satisfaction in adults with intellectual disabilities by obtaining the perspective of their parents. A questionnaire was used to collect the viewpoints of parents with adult children who have an intellectual disability in sports facilities. This questionnaire aimed to gather responses in relation to close-ended questions based on three dimensions: the reasons for participating in sports; general expectations of the sporting activities; and the effects of exercise in relation to adults with intellectual disabilities. The questionnaire was given to a sample set of 400 parents. 120 of these parents responded to and returned the questionnaire addressing the objectives of the study. The findings revealed that there are significant barriers that prevent people with intellectual disabilities from playing sports—including lack of training programs, the absence of their rights, and the difficulties of accessing sports facilities.

Microstrip antenna perturbed by a defected ground structure with a reconfigurable polarization capability

In this article, a novel square microstrip antenna with a reconfigurable polarization capability is proposed that utilizes a perturbing segment in a defected ground structure (DGS). To verify the perturbing method, DGSs were embedded into either the two diagonal or all four corners of an antenna. The reconfigurable characteristics are produced by independently controlling the states of the biased DGS PIN diodes. The simulated and measured results show good frequency agility and polarization diversity with remarkable radiation performances. © 2011 Wiley Periodicals, Inc.

Series-impedance of underground transmission systems

A general solution for the magnetic field in the soil is developed that satisfies arbitrary boundary conditions on an underground cylindrical surface at a finite depth below an earth/air plane surface. A quasi-steady state hypothesis is assumed. The series impedance of an underground cable with a perfectly conducting sheath is evaluated taking into account skin effect in the soil. The numerical results are compared with F. Pollaczek's (1926) classical solution. >
Two-dimensional mode size transformation by /spl Delta/n-controlled polymer waveguides

We report a new type of polymer waveguide for two-dimensional (2-D) mode size transformation in which /spl Delta/n (refractive index difference between core and cladding) is properly controlled along the waveguide axis while the core cross section is kept uniform. The beam diameter in the /spl Delta/n-controlled waveguide where the core diameter is 3.7 /spl mu/m and /spl Delta/n changes from 0.0027 to 0.0009 toward one end in the 5 mm-gradient /spl Delta/n, region, is about twice as large as that in a normal waveguide where /spl Delta/n is 0.0027. The optical loss accompanied by mode size transformation is calculated to be less than 2.5% based on beam propagation methods (BPM's).
An undergraduate instructional course on microelectromechanical systems fabrication

This paper describes a single quarter instructional course concerned with the design and fabrication of microelectromechanical systems (MEMS) devices. This course entitled "Design and Fabrication of Microelectromechanical Systems" has now been taught twice at the University of Minnesota. The course is offered for juniors, seniors, and first-year graduate students majoring in electrical engineering, mechanical engineering, chemical engineering, and material science. The participants are not required to have a background in microelectronics processing techniques. This course is taught starting with a perspective of basic silicon processing techniques, and it advances to demonstrate how such processing methods can lead to fabricated MEMS devices. Several key components are integrated in this course: (1) hands-on fabrication of micromechanical motor structures in a Class 100 cleanroom; (2) approximately 30 hours of entry-level classroom lecture on solid-state micromachining and related fabrication technologies; (3) testing and analysis of finished structures and devices; and (4) weekly discussions of fabrication results and MEMS work being carried out at other institutions.
Calculations of electromagnetic fields in longitudinal irregular TEM-cells

Abstract. TEM-cells can be used as a standardized field generator for field probe calibration purposes or electromagnetic compatibility measurements. Because of its practical use as a measurement environment, the electromagnetic behavior over a broad range of frequencies is essential. However, without the understanding of wave reflection, mode-conversion, and attenuation, using such a measurement environment is impractical. In this contribution, we calculate the electromagnetic fields in a longitudinal irregular coaxial TEM-cell. Using a semi-analytical approach, we can determine these wave characteristics. The method is based on the projection of Maxwell's equations onto eigenfunctions. This work's primary objective is to examine the effect of irregular deformed boundaries on the electromagnetic field and the resonance frequencies.
Optimal self-scheduling and bidding strategy of a thermal unit subject to ramp constraints and price uncertainty

This study proposes methods for solving the optimal self-scheduling and bidding strategy of a thermal generating unit subject to ramp constraints and price uncertainty. In the first-half of the study, the authors propose a polynomial algorithm for deterministic self-scheduling for the generating company (GenCo) to optimally respond to day-ahead markets assuming market prices can be precisely forecasted. The authors then consider the GenCo bidding to real-time market in the second-half of the study. A multi-stage stochastic program is set up, where in the first stage the GenCo makes a decision as whether it should submit a bid or change an existing bid to the real-time market. In case that the GenCo participates in the first stage, the unit is dispatched by the market in the next stage. Then the process repeats. The authors propose a regression-based method to approximate the recourse function and determine the optimal commitment and dispatch policy for the GenCo, which yields the optimal bidding strategy for the GenCo to participate the real-time spot market.
Development and evaluation of a new rear-impact crash dummy: the RID2

Whiplash injuries resulting from car collisions cause human suffering and high social costs because of the long-term impairment of victims. Low severity neck injuries are a serious problem in our society. In 1997, the European Whiplash project started with the aim to develop passive safety methodologies in order to reduce the frequency of neck injuries in rear-end impacts. This project has resulted, among others, in a rear impact crash dummy, the so-called RID2. The objective of this paper is to present the design of the dummy and to present its performance in comparison with human volunteer and post mortem human subject (PMHS) tests. A comparison is also made with the Hybrid III dummy in similar test conditions. In general, the responses of the head-neck system of the RID2 in low severity rear impact evaluations correlate better to the human subject tests than the Hybrid III responses, in both the car seat tests and the rigid tests. In the comparison with human volunteers in a real car seat, both the RID2 and the HYBRID III showed realistic kinematics. In this paper, the RID2 dummy has been compared with two sets of human subject data. It is strongly recommended to evaluate the dummy in other test conditions for which data has recently become available. The world-wide testing of the dummy is planned for 2001 and 2002 and includes several of such evaluations and also includes comparison testing with alternative test devices like the THOR dummy and the BioRID dummy.
Central Equatorial Pacific Warming and Freshening in the Twentieth Century: Insights From a Coral Ensemble Approach

The tropical Pacific influences climate patterns across the globe, yet robust constraints on decadal to centennial‐scale climate variations are difficult to extract from sparse instrumental observations in this region. Oxygen isotope (δ18O) records from long‐lived corals enable the quantitative reconstruction of tropical Pacific climate variability and trends over the twentieth century and beyond, but such corals are exceedingly rare. Here, we use multiple short coral δ18O records to create a coral ‘ensemble’ reconstruction of twentieth century climate in the central tropical Pacific. Ten U/Th‐dated fossil coral δ18O records from Kiritimati Island (2°N, 157°W) span 1891 CE to 2006 CE, with the younger samples enabling quantitative comparison to a large ensemble of modern coral records and instrumental sea surface temperature. A composite record constructed of modern and fossil Kiritimati coral δ18O records shows a shift toward warmer and fresher conditions from 1970 CE onward, consistent with previously published records in this region.
Real-time 3D Navigation-based Semi-Automatic Surgical Robotic System for Pelvic Fracture Reduction*

Pelvic fracture is a serious high-energy injury with highest disability and mortality rate among all fractures. At present, the reduction of pelvic fracture is still completely dependent on surgeons' experience, which may lead to poor effect of pelvic reduction, thus seriously affecting surgical treatment and postoperative rehabilitation of patients. Based on this, a new robotic system for pelvic fracture reduction was developed and tested. Withdrawing on the optical tracking system, the real-time 3D navigation of pelvic position during operation was realized through Nonrigid ICP method. The target position for fracture reduction was obtained through pelvic symmetry reduction method based on structural symmetry of the pelvis. The shortest reduction path was planned automatically, which could be adjusted by surgeons manually. Finally, the pelvic fracture reduction operation was completed through the robot. System accuracy and effectiveness were demonstrated through laboratory trials and preliminary cadaveric trials. The system resulted in high fracture reduction reliability with the registration accuracy of 1.3749 ± 0.6311mm, and the robot reduction accuracy of 2.8925 ± 0.8647mm. Preliminary cadaveric trials also provided a positive and favorable outcome pointing to the usability of the system in the operating theatre, potentially enhancing the capacity of pelvic fracture surgeries.
Laser-Based Side-by-Side Following for Human-Following Robots

A mobile robot that follows behind humans in structured environments has to face the challenge of full occlusion caused by the walls when the target person makes a turn at the corridor intersections. This may result in short-term, even a permanent loss of the target from the field of view of the Human-Following Robots (HFRs). Concerning this issue, a novel side-by-side following method for HFRs is addressed. In this paper, HFRs detect the legs of target person and different types of corridor intersections using the onboard laser scanner at first. Then, we provide a corridor detector method to cluster the geometric structure constraint between the target and corridor intersections. At last, a Side-by-side Following Leg Tracker (SFLT) is designed by integrating the laser information, in order to increase the visible time of the target person, while the target is turning at the corridor intersections. The corridor detector method and SFLT method have been simulated in MATLAB. Moreover, the approach of side-by-side following has been implemented in the Robot Operating System (ROS) of real-life robots in the corridor environment. The results from simulation and practical experiment show that, by using our method, HFRs were able to successfully follow the human92.0% while a mobile robot meeting potential occlusions at corridor intersections.
A protocol for systematic review and meta-analysis

Background: Prostate tumor overexpressed-1 (PTOV1) was firstly depicted as gene and protein overexpressed in prostate cancers and preneoplastic lesions of high-grad intraepithelial neoplasia. Recently, people have paid recent attention to the oncogenic PTOV1 protein as a regulator with various cellular functions and pathways that tend to enhance cell growth and self-renewal in numerous cancer cell types. Its prognostic role in cancers remains controversial. Methods: Eligible studies are identified by comprehensively searching literature in all available databases. The associations between PTOV1 expression and overall survival, disease-free survival, relapse-free survival, progression-free survival, and clinicopathological characteristics are estimated by employing hazard ratios and the confidence intervals of 95%. STATA 12.0 software was adopted to perform the meta-analysis. Results: This study will provide high-quality synthesis to evaluate the associations between PTOV1 expression and overall survival, disease-free survival /relapse-free survival , progression-free survival, and clinicopathological features. Conclusion: The study will provide updated evidence to assess whether the expression of PTOV1 is in association with poor prognosis in patients with cancers. PROSPERO registration number: CRD42020183853. Abbreviations: 95% CIs = 95% confidence intervals, HRs = hazard ratios, PTOV1 = prostate tumor overexpressed-1, RFS = relapse-free survival.
