P‐16: A Novel Driving Scheme to Achieve Low Frame Rate and Low Power Consumption with Narrow Border

To improve the display effect at low illumination of low frame rate display, two sets of scan driving circuits must be adopted. Therefore, the border must be widened to place two sets of scan driving circuits and one set of emit circuits, which conflicts with the need of narrow border for AMOLED display. In this paper, a novel driving architecture that placed two set of circuits alternatively by one side is proposed to meet the low frame rate and narrow border at the same time.

Interior Bowers

I know a rural bedroom with a paper representing a trellis and Noisette roses climbing over it; the carpet is shades of green without any pattern, and has only a narrow border of Noisette roses; the bouquets, powdered on the chintzs, match, and outside the window a spreading bush of the same dear old-fashioned rose blooms three parts of the year. That is a bower indeed, as well as a bedroom (Barker, 1878, p. 11). In Bedroom and Boudoir (1878) Lady Barker describes a number of bedrooms and boudoirs furnished with ornamental linings derived from the natural landscape. As the most private, internal and intimate interior spaces in the Victorian home, such spaces are likened to bowers - clearings in the forest, retreats or nests. Surrounded by surfaces composed of vegetal patterns and colours, the boudoir shows signs of reclaiming vestiges of the outside, not as the manicured garden or the cultivated landscape, but as foreign wilderness. Barker’s remarks critique the notion of the interior as tectonically distinct from the exterior. In contrast, the room is shown to be derivative of the exterior through its use of ornament, furnishings and linings. This paper examines the relationship between boudoir and bower as established by Lady Barker. It then traces the physical description through theoretical positions of the time on the relation of ornament and nature, in order to position the boudoir as an interior space of decorative and tactile envelopment.

Planning of UAV Flight Routes in the Problems of Group Patrolling of the Extended Territories

Currently one of the promising areas of joint use of unmanned aerial vehicles (UAVs) is group air patrolling of large territories. Here the organization of patrolling assumes the solving the planning problem of routes flight of UAV group. The paper considers the problem of optimal planning of flight routes of the same type of UAVs during group patrolling of large territories. The territorial waters or narrow border areas of any State may serve as an example of such territories. It is suggested that the patrolled area has an elongated shape and is divided into a chain of adjacent patrol zones prescribed by a separate UAV. The drone’s flight route passes through adjacent zones. The flight task performed periodically by each drone consists in moving it to a given flight zone, collecting operational data and transmitting this data to a control point (center, station). The optimization aspect of UAV flight route planning is to minimize the maximum time required to complete flight tasks. The considered problem of group patrolling reduced to the multiple traveling salesman problem — one of the classic intractable combinatorial optimization problems. A brief analysis of modern methods for solving the multiple traveling salesman problem is given. Due to the lack of effective exact methods for solving this problem, it is natural to use approximate heuristic and metaheuristic methods focused on solving NP-hard optimization problems, reducing the full search and giving a solution close to the exact one. The multiple traveling salesman problem considered in this paper is reduced to the problem of integer linear programming, for the solution of which a genetic algorithm implemented in MATLAB based on the mathematical package Global Optimization Toolbox is proposed. An illustrative example of patrolling by three UAVs of an extended territory with 11 adjacent zones is considered. Computational experiments confirm the effectiveness of the algorithmic solutions proposed in the work.

Amorphous IGZO Thin-Film Transistor Gate Driver in Array for Ultra-Narrow Border Displays

A gate driver in array (GIA) design based on the amorphous indium gallium zinc oxide (a-IGZO) thin-film transistor (TFT) is developed for narrow border displays. In the design, each TFT in the gate driver circuits is divided into a certain number of smaller size devices, which can be placed in different subpixels. Therefore, the pixel aperture ratio loss is minimized, and uniform placement of the gate driver circuits over the pixel array area is able to be achieved. The proposed step-like repeating block structure further reduces the occupied area of the signal interconnects. A 12.4-inch fringe field switching (FFS) liquid crystal display (LCD) panel of ultra-narrow border (0.5 mm) is demonstrated with reliable operation based on this GIA design, proving its potential for practical applications.

Developed electrochemical sensors for the determination of beta-blockers: A comprehensive review

Beta-blockers (β-blockers) are a special type of medicine that are prescribed for a wide range of health problems including cardiovascular diseases. There is a narrow border between the therapeutic and toxic levels of β-blockers and at high dosages. β-blockers can cause serious side effects. Besides, β-blockers are used as a doping agent at some sports and their usages is banned by world anti-doping agency (WADA). Therefore, developing a simple, precise and sensitive methodology to determine β-blockers is greatly important. Among the different reported analytical approaches for β-blockers quantification, electroanalytical techniques offer high sensitivity, wide dynamic range, straightforward instrumentation, low price and short analysis time. The applicability in opaque and colored samples, high selectivity and the capability at determining several components simultaneously are other upsides of electrochemical sensors. In this regard, this review copes with critically comparing electrochemical sensors as well as measurement protocols for electroanalytical measurement of β-blockers. It is also highly concentrated on the employed working electrodes and their modification that are vital for effective determination. Moreover, important conclusions are made from the surveyed studies and some propositions are presented for future works.

Aqueous vaginal contrast and scheduled hematocolpos with magnetic resonance imaging to delineate complex müllerian anomalies

To demonstrate the advantage of using aqueous vaginal contrast and scheduled hematocolpos with magnetic resonance imaging (MRI) to improve the delineation of gynecologic anatomy and to recommend that this modality be considered in patients with complex müllerian anomalies. Video demonstration of MRI adjuncts to improve visualization of gynecologic anatomy. Academic Hospital. A patient with obstructed hemivagina and ipsilateral renal agenesis (OHVIRA) who presented for definitive surgical management. OHVIRA is a unilateral obstructed müllerian anomaly that presents typically after menarche with progressively worsening dysmenorrhea caused by progressive distension of the obstructed hemivagina and uterine horn. The definitive treatment for this anomaly is resection of the unilateral obstruction. When the obstructed hemivagina is within close proximity to the patent hemivagina, vaginal septum resection should be performed to relieve the obstruction successfully. However, when the obstructed hemivagina and uterine horn are not adjacent to the patent hemivagina, a simple septum resection is not feasible and there is a high rate of restenosis if anastomosis is attempted. In this case, laparoscopic removal of the obstructed uterine horn, fallopian tube, cervix, and vagina should be considered as an alternative approach to resolving the obstruction. A surgical approach can be recommended only once the surgeon has a clear understanding of the patient's pelvic anatomy and the magnitude of the obstruction. In the presented case, a 17-year-old patient with OHVIRA presented for definitive surgical management. While on hormonal suppression, a pelvic MRI was performed that identified a uterus didelphys with a left hemiuterus and cervix communicating with a patent vagina. The right hemiuterus and cervix were measured 2.5 cm from the patent vagina. However, because of hormonal suppression, the vaginal cavity was decompressed, making it very difficult to discern the relationship between the two uteri and vaginas. To better determine whether vaginal septum resection to relieve the obstruction was feasible, norethindrone was discontinued to allow menstrual blood to fill the obstructed hemivagina followed by a subsequent pelvic MRI with aqueous vaginal contrast to fill the patent vagina with contrast gel to improve the visualization of the decompressed vaginal cavities. Advantage of aqueous vaginal contrast and scheduled hematocolpos with MRI to image pelvic anatomy in a patient with a complex müllerian anomaly to guide surgical decision-making. The addition of vaginal aqueous contrast clearly delineated the course and caliber of the patent vagina and its relationship to the obstructed hemivagina, now filled with blood. The inferior margin was in closer proximity to the patent vagina, but with only a very narrow segment (<1 cm) adjacent to the patent vagina and the obstructed cervix was displaced superiorly, now measuring 3.5 cm above the patent vagina. Surgical management options were discussed with the patient, and given the superior location of the obstructed uterus and cervix with only a narrow border of the vagina in continuity with the patent vagina, the risk of postoperative stenosis after vaginal septum resection was determined to be too high. The decision was made to proceed with a laparoscopic resection of the obstructed right side, and the patient underwent laparoscopic resection of the right hemiuterus, fallopian tube, cervix, and vagina. Intraoperatively, a survey of the pelvis again confirmed that the two vaginas were too far to reconnect safely without a high risk of stenosis. The patient recovered without complications postoperatively and her menses resumed without any pain. We highlight the use of two techniques to optimize MRI imaging of pelvic anatomy in a patient with a complex müllerian anomaly. First, the use of aqueous vaginal contrast with MRI is advantageous to clearly delineate the course and caliber of the patent vagina in patients with complex gynecologic anatomy. Second, cessation of hormonal suppression to allow menstruation to cause hematocolpos helped delineate the relationship between the obstructed vagina and patent vagina. In the presented case, these MRI adjuncts provided necessary detail that could not be appreciated with standard MRI to confirm that vaginal septum resection to preserve the right uterus would be too high a risk for postoperative stenosis in this patient. Aqueous vaginal contrast and scheduled hematocolpos should be considered as adjuncts to MRI when standard imaging modalities are unable to clearly describe the relationship between pelvic structures in cases of complex müllerian anomalies to help guide treatment recommendations.

Small Antenna Design of Triple Band for WIFI 6E and WLAN Applications in the Narrow Border Laptop Computer

This paper presents the design of a small antenna for use in a wireless local area network (WLAN) and Wi-fi 6E on a narrow-border laptop. The dimensions of the antenna are 43 × 3 × 0.4 mm3, and it features a grounding system simulated by a 200 × 260 mm2 copper plate. At low-frequency bands, a couple-fed right arm can excite the fundamental at 2.45 GHz in the λ/4 resonant mode to cover the range of 2.4–2.848 GHz. At higher bands, the couple-fed left arm and direct-fed right arm can control the higher 3λ/4 mode at 5.825 GHz and 5λ/4 mode at 6.85 GHz. The direct-fed left arm excites the fundamental at 5.16 GHz in the λ/4 resonant mode and, with integration of 5.16, 5.825, and 6.85 GHz, can fully cover the range of 5.15–7.125 GHz. In far-field measurements, the peak gain and efficiency in a WLAN with Wi-Fi 6E were 0.82 and 2.58 dBi and 53% and 68% in the low and high bands, respectively. Overall, the experiments revealed that the antenna exhibits a sufficient level of performance for a narrow-border laptop.
