Published: July 2023

BackgroundTo determine the incidence and identify the predisposing factors for allogeneic blood transfusion (ABT) in patients with rheumatoid arthritis (RA) undergoing primary unilateral total knee arthroplasty (TKA).MethodsA total of 702 patients with RA who underwent primary unilateral TKA between 2003 and 2022 at a single center, were retrospectively enrolled. Patients were stratified into the ABT and non-ABT groups. Data on patient demographics, laboratory parameters, and disease- and surgery-related parameters were collected from chart reviews and compared between the ABT and non-ABT groups. Multivariate logistic regression analysis was conducted to identify the possible factors associated with postoperative ABT.ResultsA total of 173 (24.6%) patients underwent ABT after surgery. Significant risk factors for ABT included the degree of flexion contracture [odds ratio (OR) = 1.018, P = 0.005] and thickness of insertion (OR = 1.170, P = 0.014). Conversely, body mass index (OR = 0.937, P = 0.018), preoperative hemoglobin level (OR = 0.973, P &lt; 0.001), and intraoperative use of tranexamic acid (TXA) (OR = 0.119, P &lt; 0.001) were associated with a lower risk of ABT in TKA.ConclusionWe identified the significant risk and protective factors for ABT during TKA in patients with RA. This information could be helpful in optimizing perioperative blood management strategies during these surgeries.

IntroductionThis study investigated the effects of maggot antimicrobial peptides on growth performance, blood parameters, immune organ index, and cecum microbial diversity in yellow broilers.MethodsThe addition of 100–300 mg/kg maggots antimicrobial peptides to the corn-soybean meal basal diet was evaluated. Two hundred and forty one-day-old yellow-feathered broilers were randomly divided into four groups (60 chickens in each group): basal diet group (BC group), basal diet group + 100, 200, 300 mg/kg maggots antimicrobial peptides (MDAL group, MDAM group, and MDAH group).ResultsThe result showed that the average daily feed intake (ADFI) of the BC group, MDAM group, and MDAH group was higher than that of the MDAL group (P &gt; 0.05), the average daily gain of MDAM group and MDAH group was significantly higher than that of BC group and MDAL group (P &lt; 0.05), but the feed-weight ratio (F/G) was significantly lower than that of BC group (P &lt; 0.05). The total protein (TP) content in the MDAM group and MDAH group was significantly higher than that in the BC group (P &lt; 0.05), and the albumin (ALB) content in the MDAH group was higher than that in the BC group (P &gt; 0.05). The contents of IgA and IgG in the MDAH group were significantly higher than those in the BC group (P &lt; 0.05). In contrast, the content of alanine aminotransferase (ALT) in the MDAH group was significantly lower than that in the BC group (P &lt; 0.05). The thymus and spleen indexes of the MDAH group were significantly higher than those of the BC group (P &lt; 0.05). 16S rDNA sequencing results showed that Bacteroidota and Bacteroides were the dominant phylum and genus of cecal microorganisms at the phylum and genus levels, respectively. Cecum microorganisms are mainly involved in biological processes such as energy production and conversion, amino acid transport and metabolism, and carbohydrate transport and metabolism.DiscussionIt was concluded that adding different doses of maggot antimicrobial peptide to the basal diet could improve yellow-feathered broilers' growth and immune performance and change the cecum flora. The appropriate dose of antimicrobial peptide addition was 300 mg/kg.

Published: July 2023

Kısırlaştırma işlemi hayvanların üremesini kalıcı bir şekilde durdurmak için yapılan cerrahi bir müdahaledir. Ülkemizde sahipsiz sokak hayvan sayısı milyonlarla, buna karşılık kısırlaştırılan sokak hayvan sayısı binli sayılarla ifade edilmektedir (Tarım ve Orman Bakanlığı,2022). Sokakta yaşayan, başıboş kedi köpek gibi evcil hayvanların popülasyonundaki kontrolsüz büyümenin önüne geçmek için kısırlaştırma işlemleri yerel belediyelere ait geçici hayvan bakımevlerinde yapılır. Kısırlaştırma işlemi anestezi eşliğinde yapılan basit bir operasyon olarak görünse de alt süreçlerine bakıldığında olası hataların oluşturacağı tehlike ve risklerle göz ardı edilmemesi gereken bir süreçtir. Bu konuda potansiyel tehlikelerin belirlenmesi ve sonuçlarının analizini yapılması risk değerlendirmeleri ile mümkün olur. FMEA (Hata Tür ve Etkileri Analizi Risk Analizi), basitliği ve görünürlüğü göz önüne alındığında başta sağlık hizmetleri olmak üzere çoğu alanda kalite iyileştirme çalışmaları için sıklıkla kullanılan bir yöntemdir. Uygulaması kolay ve maliyeti düşüktür. Bu yöntemle yüksek riskli süreçlerde oluşabilecek hatalar önceden tespit edilerek, hastaya ulaşmadan önce önlem alınabilir ve böylece hataların oluşma sıklığı düşürülebilir.
İş sağlığı ve güvenliği kapsamında yapılan risk değerlendirme çalışmaları çalışanın ve çalışma ortamının risklerini değerlendirmek için yapılır. Çalışmamızda gerçekleştirilen risk analizi ile geçici hayvan barınakları ve burada kısırlaştırılan hayvanların sağlık ve güvenliği hedeflenmiştir.
FMEA yöntemi kullanılarak yapılan analizde; öncelikle bir risk analiz ekibi kurularak, iş akış şeması çıkarılmıştır. Ardından operasyon için adım diyagramları hazırlanmış ve tehlikeler tespit edilmiştir. Sonuçta oluşturulan risk analizi uzman ekip tarafından değerlendirilmiştir. Buna göre geçici hayvan barınaklarında gerçekleştirilen kısırlaştırma işleminin FMEA ile 6 tane alt süreç irdelemesi yapılmış, toplamda 17 olası hata türü belirlenmiştir. Hata türlerinin tayin edilen olasılık ve şiddetine bağlı olarak risk skorları bulunmuştur. Yapılan risk değerlendirmesinin kazaları meydana getirebilecek her türlü unsurun bertaraf edilmesinde önemli etkisinin olduğu açıktır.

Increased ranging accuracy of RFID tags in ETSI regions using 53MHz wide dual bands
Authors: Le Breton Mathieu 
Published: July 2023

<p>Passive RFID tag localization has numerous applications, which can benefit from improved accuracy. Ranging methods based on phase difference of arrival become more accurate with higher frequency bandwidth. European regions, following ETSI regulation, historically allowed a single ultra-high fre-quency band (865–868 MHz) with limited accuracy. Recently allowed, the second band (915–921 MHz) increases the fre-quency range from 1.8 MHz to 53 MHz, but with a significant gap between the bands. In a dual-band experiment, distance estimates were obtained between two reader antennas and 17 tags across 6 arrays. The results revealed a new 3.07 m ambi-guity cycle due to the frequency gap, that adds to the existing 0.17 m phase ambiguity. Solving the new ambiguity on 88% of tag-antenna combinations and 100% of the arrays resulted in a maximum error of 0.55 m (median 0.26 m), significantly im-proving accuracy (×6.5) compared to the former single-band ranging. Looking ahead, the adoption of dual-band ranging could enhance the accuracy of various tag localization methods in ETSI-regulated regions.</p>
OMSLD: Occlusion-Aware Multi-human Segmentation in Low-resolution Infrared Dynamic Scene
Authors: Yang Mengni , Yang Bo , Shi Haoxiang 
Published: July 2023

<p>Due to the advantages of preserving privacy, low-resolution thermopile infrared array sensor (TPAS), as an alternative to visible light sensor, has gained increasing attention for real-time perception and monitoring of indoor human targets. However, most recent research focus on single individual just because of its low resolution. Additionally, there are many dynamically changing heat sources besides human targets in indoor environments. The switching states, positional movements of interfering heat sources, as well as occlusions between interfering heat sources and humans and among humans themselves, pose a great challenge and bear significance to the task of removing dynamic background and distinguishing occluded human instances in low resolution. This paper proposes a new infrared occluded multi-human segmentation network based on Mask R-CNN and designs a new multi-scale fusion feature pyramid detection network. A hardware platform is constructed based on a TPAS with 24×32 pixels. The improved Mask R-CNN can effectively segment occluded multi-human instances even in low-resolution dynamically changing scenarios. However, there is still possible to segment dynamic indoor heat sources as human targets. To address this issue, this paper introduces an adaptive Gaussian background removal algorithm applying a priori map for multi-human (AGBR-PMM). A combination of these two methods in low-resolution scenes achieves good segmentation of occluded human instances while eliminating interferences from dynamic indoor scenes. This lays the foundation for subsequent human behavior recognition using low-resolution thermopile infrared array sensor. </p>
Developing an automated testing framework to support the validation of REDCap, an electronic data capture system
Authors: De Fouw Adam 
Published: July 2023

<p>REDCap, a widely used electronic data capture tool for clinical and translational research, receives crucial support from various committees and groups within the extensive network of institutional collaborators known as the REDCap Consortium. For example, the Regulatory and Software Validation Committee defines and releases manual validation test scripts intended to aid institutions in the testing and validation efforts of their institutional REDCap deployments. Although these resources are important and valuable, the manual testing process itself has certain limitations such as time-consuming test execution and potential for inconsistent database state. </p>
<p>To address some of the limitations of manual testing, a group of software developers within the Regulatory and Software Validation Committee wrote and released automated feature test scripts using an automated testing framework called the REDCap Cypress Test Framework. This report provides an overview of the REDCap Cypress Test Framework and its potential to improve the testing and validation of REDCap through automated testing.</p>

Published: July 2023

<p>The precise measurement of sleep stages is crucial for evaluating sleep quality. Deep learning has recently been utilized for automatic sleep stage classification, demonstrating exceptional performance. Previous studies on deep learning-based sleep stage classification assumed stationary data generation environments, where samples were drawn from fixed – albeit unknown – unknown distributions and annotated based on predefined criteria. However, this assumption of a stationary distribution is no longer valid in real-world applications due to shifts in data distribution between new and old datasets and changes in classification tasks. Moreover, the unavailability of historical data often poses challenges in training deep learning models. Sleep stage classification faces challenges associated with evolving data acquisition, changing patient demographics, and shifting annotation criteria over time. This paper addresses the classification of sleep stages with varying data distributions, missing historical datasets, and changing label granularity for the first time. We proposed learning strategies for addressing the challenges described above, as well as constructed benchmarks for evaluating the proposed learning strategies. The results demonstrate the effectiveness and performance of the proposed learning strategies. These findings provide compelling evidence for the significance and impact of this work. Furthermore, a comprehensive discussion is presented, highlighting the limitations of our approach, and proposing several avenues for future research. </p>

<p>We investigate an economic readout for depth-of-interaction (DOI) and time-of-flight capable PET detector that consists of an N×N array of crystals whose light outputs at the front- and back-end surfaces are detected by using silicon photomultipliers (SiPM). The N×N SiPMs at the front-end (back-end) of the detector are read by a stripline configured to support discrimination of the row (column) position of the signal-producing crystal, producing only four outputs for the detector. To evaluate this design, we built 4×4 and 8×8 detector modules (DM) by using 3.0×3.0×20 mm3 lutetium-yttrium oxyorthosilicates. The outputs were sampled at 2 GHz and processed offline. For both DMs, crystal discrimination was successful. For the 4×4 (8×8) DM, we obtained a crystal-level energy resolution ranging from 11.3% to 19.3% with an average of 14.1% (9.5% to 21.6% with an average of 13.9%), an average DOI resolution of 2.5 mm (3.1 mm), and a best coincidence resolving time (CRT), measured in coincidence with a single-pixel reference detector with a 302 ps CRT, of 391 ps (603 ps). The CRT deteriorated with the (8×8) DM possibly due to intercrystal scattering.</p>
Thomas Hardy's Tess of the d'Urbervilles:The epresentative of a Tragic Hero

Published: July 2023

Tess of the d'Urbervillesis Thomas Hardy's novel that tackles the story of Tess Durbeyfield, a working-woman in the farm of d'Urbervilles. She works so as to help her family in getting living. Jack Durbeyfield, Tess's father has no job. He spends his days in drinking wine. Tess looks like her mother, Joan Durbeyfield, in that both of them are uneducated and beautiful women. Alec d'Urbervilles forced Tess to be raped by him. She cannot oppose him because he is her master in work on one hand, and she is ignorant in the sexual relation-shipsbetween man and woman and the outcomes connecting from such arelationship.
Hardy condemns the passivity of Tees. Being a passive person means to loose; means to be aimless, dependent, and having conforming to the fate without any resistance. Tess is passive in not attacking, defending herself from Alec's seduction at the beginning. She is passive in accepting Angel Clare's decision to leave her―at the night of confession―at the end. She had better counteract the outsider attacks. She is partly responsible for her tragic flaw and the other responsibility lies upon her mother, Joan. Her mother did not advice, and did not tell her how to guard herself. By tragic flaw, it is the destructive factor generated from the defects in the character that lead to
destroy the charactertotally.
