Abstract
Nth degree Truncated polynomial Ring Unit (NTRU) is one of the famous post-quantum cryptographic algorithms. Researchers consider NTRU as the most important parameterized family of lattice-based public key cryptosystems that has been established to the IEEE P1363 standards. Lattice-based protocols necessitate operations on large vectors that makes parallel computing one of the appropriate solutions to speedup it. NTRUEncrypt operations contain a large amount of data that requires many repetitive arithmetic operations. These operations make it a strong candidate to take advantage of the high degree of parallelism. The main costly operation which is repeated in all NTRU algorithm steps is the polynomial multiplication. In this work, a Parallel Post Quantum NTRUEncrypt algorithm called PPQNTRUEncrypt is proposed. This algorithm exploits the capabilities of parallel computing to accelerate the NTRUEncrypt algorithm. Both analytical and Apache Spark simulation models are used. The proposed algorithm enhanced the NTRUEncrypt algorithm by approximately 49.5%, 74.5%, 87.6%, 92.5%, 93.4%, and 94.5% assuming that the number of processing elements is 2,4,8,12,16, and 20 respectively.

Abstract
This paper discusses the charmonium and bottomonium correlators in the pseudoscalar channel and the corresponding spectral reconstruction on the lattice. The absence of a transport peak in the pseudoscalar channel spectral function allows for an easier study of the in-medium modification of bound states. However, extracting spectral information from Euclidean correlators is still a numerically ill-posed problem. To constrain the spectral reconstruction, we use an ansatz motivated from perturbation theory. The perturbative model spectral function has two main contributions: a thermal part around the threshold obtained from pNRQCD and the vacuum part well above the threshold. These two regions are matched continuously, and the model spectral function is obtained by introducing parameters that control the overall thermal shift of the peak and the overall amplitude. The lattice correlator data is computed using clover-improved Wilson valence fermions on large and fine gauge field configurations generated using $N_f=2+1$ flavors Highly Improved Staggered Quark (HISQ) action with physical strange quark mass $m_s$, and slightly heavy degenerate up and down quark masses $m_l=m_s/5$ that correspond to $m_\pi\simeq 320$ MeV. Our results obtained at $T=220$ MeV and $T=251$ MeV suggest that no resonance peaks are needed to describe the charmonium lattice data at these temperatures, while for bottomonium thermally broadened resonance peaks persists.

Abstract
Purpose;
To determine the causes of benign hepaticojejunostomy strictures (BHSs) after pancreaticoduodenectomy (PD) and the outcome of endoscopic retrograde cholangiography (ERC) treatment for BHSs.
Methods;
A total of 175 patients who underwent PD between January 2013 and December 2020 and who were able to be followed up for at least 1 year were included. The preoperative data, operative outcomes, and postoperative course were compared between the BHS group and the group of patients who did not develop stenosis during follow-up (non-BHS group). The course of treatment in the BHS group was also tabulated.
Results;
Of the patients who underwent anastomosis of the common hepatic duct and jejunum, 13 required invasive treatment due to BHS (7.4%). Multivariate analysis in the BHS and non-BHS groups identified male sex (OR; 3.753, 95% CI; 1.029–18.003, P = 0.0448) and a preoperative bile duct diameter less than 8.8 mm (OR; 7.51, 95% CI; 1.75–52.40, P = 0.0053) as independent risk factors for the development of BHS. In the BHS group, all patients underwent ERC using enteroscopy. The success rate of the ERC approach to the bile duct was 92.3%. Plastic stents were inserted in 6 cases, and metallic stents were inserted in 3 cases. The median observation period since the last ERC was 17.9 months, and there was no recurrence of stenosis in any of the 13 patients.
Conclusions;
Patients with narrow bile ducts are at higher risk of BHS after PD. Recently, BHS after PD has been treated with ERC-related procedures, which may reduce the burden on patients.

Abstract
Melatonin, synthesized in the pineal gland, affects the hypothalamus, leading to the release of gonadotropins during the transition period in sheep and goats. Melatonin regulates the production of prolactin in lactotrophic cells and of follicle-stimulating hormone and luteinizing hormone in gonadotropic cells. Melatonin may also provide better reproductive performance through its positive effects on reproduction, such as improving oocyte quality, favoring embryo implantation, reducing oxidative stress, and protecting the offspring by increasing progesterone levels. Melatonin applications in sheep are generally carried out during anoestrus and transition periods. In this study, the effect of exogenous melatonin used with different methods on estrus onset, fertility, plasma progesterone, and malondialdehyde (MDA) concentration will be examined during the breeding season in sheep. For this purpose, the ewes were assigned to three groups: Group I (MEL): Subcutaneous administration of 18 mg of melatonin (Regulin, Ceva-Türkiye) Group II (MELPRO): Subcutaneous administration of 18 mg melatonin (Regulin, Ceva-Türkiye) + Intravaginal sponge containing 20 mg of flugestone acetate for 9 days (Choronogest CR- France) + As soon as the sponge is removed, intramuscular PGF2α (250 µg cloprostenol, Senkrodin-Vetaş-Türkiye) Group III (CON): 1 ml of physiological saline was administered subcutaneously for the placebo effect. As a result, in ewes, only exogenous melatonin administration during the natural breeding season causes a short delay in the time to first estrus. Melatonin increases progesterone concentration on day 17 of gestation in the natural breeding season. The positive reproductive effects of melatonin may increase the multiple birth rate and litter size.

Published: May 2023

Abstract
Operational amplifiers (op amps) are fundamental blocks that find wide application both as stand-alone devices and as crucial building blocks embedded in various Systems on Chips (SoCs). Achieving high defect coverage as well as performing diagnosis and defect localization in these circuits has been proven to be a difficult/expensive task even with sophisticated analog and digital testing circuitry. ISO26262 Standard for functional safety (FuSa) places stringent requirement that an automotive IC must have a very high defect coverage (usually greater than 90%). This reinforce the need to improve the robustness in the design of analog and mixed signal (AMS) circuits to ensure their reliability especially if they are used in mission critical industries. This paper presents a simple defect detection, diagnosis, and localization method for op amps including Widlar current reference and biasing circuitry and can be used both for production and in-field tests for online health monitoring to ensure continued reliability during integrated circuits’ (IC) lifetime. We rigorously validate all our results using extensive transistor-level simulations of two op amps architectures (folded cascode and telescopic) designed in MUSE TSMC 180nm technology. For the folded cascode op amp, the proposed method achieves a worst-case defect coverage of 94.5% and a best-case coverage of 98%. Similarly for the telescopic op amp, the proposed method attains a worst- and best-case defect coverage of 97% and 99% respectively. Furthermore, in this work, we also propose a defect diagnosis and localization strategy using recorded bit streams from states of digital injectors and detectors.

Abstract
Fever is among the most common symptoms which lead parents and their children to the pediatrician. The most common cause of fever in children is acute infection (bacterial or viral). However, sometimes fever can be the manifestation of much more serious diseases. C-reactive protein is a marker widely used in clinical pediatric practice which helps to decide if any antibiotic treatment is needed or not. The authors present 3 case reports of children with fever from the pediatric emergency department, when the result unmeasurable capillary C-reactive protein was one of the clues in the diagnosis of severe hematology pathologies.

Published: May 2023

Abstract
The metadevice with multiple functions in a fixed nanostructure is highly required. In this paper, we numerically achieved the dual functions of switchable broadband absorption and sensitive refractive index (RI) sensing in a fixed fishnet shaped nanostructure by integrating with the phase change material vanadium dioxide (VO2). Exploiting the insulator-to-metal transition of VO2, the absorption strength could be dynamically switched from 0.07 to 0.97 in a broad terahertz (THz) band. Meanwhile, the same structure with metallic VO2 exhibits highly sensitive RI sensing performance. The sensitivity reaches 1.15 THz/RIU, which makes great progress. The proposed metasurface with dual functions will promote the development and applications of THz nanodevices.

Abstract
Background Disease perception and attitude seem to play critical roles in the cognitive impairment of individuals and may be significantly affected by healthcare professionals’ guidance in specific health behavioral changes.Objectives This study aimed to develop a questionnaire to investigate and explore the behavioral consciousness and attitudes of participants at risk of dementia during their early stage of cognitive impairment.Methods Based on the Health Belief Model and Theory, after extant literature analysis and specialist interviews, a scale of 42 question items were developed. About 283 cognitively complained MCI adults with no current or past history of dementia from our database were asked to enter this survey in our Geriatric Rehabilitation and Industry Promotion Center.Result 255 responses were obtained during this survey. The modified questionnaire includes four dimensions: susceptibility cognition (8 items), severity cognition (11 items), barrier cognition (7 items), and benefit cognition (9 items), 35 items in total. All of the internal consistency reliability, recalculation reliability, and content validity were higher than 0.89. Also, the correlation coefficient within each dimension shows a powerful relationship score from 0.874 to 0.935.Conclusion Our results supported that the MCIHB-Q has good reliability and validity, which may provide an adequate evaluation of clinical judgment in health care specialists.

Abstract
Background
To maintain and improve the quality of the cancer nursing workforce, it is crucial to understand the factors that influence retention and job satisfaction. We aimed to investigate the characteristics of cancer nurses in Australia and identify predictors of job satisfaction.
Methods
We analysed data from an anonymous cross-sectional survey distributed through the Cancer Nurses Society Australia membership and social media platforms from October 2021 to February 2022. The survey was compared to national nursing registration data. Data were analysed with non-parametric tests, and a stepwise, linear regression model was developed to best predict job satisfaction.
Results
Responses were received from 930 cancer nurses. Most respondents (85%) described themselves as experienced nurses, and more than half had post-graduate qualifications. There were 89 different titles for advanced practice nursing roles. Managing high workload was a reported challenge by 88%. Intention to leave within 10 years was reported by nearly 60%; this was significantly correlated with job satisfaction and age. Significantly higher scores for job satisfaction were associated with those who had career progression opportunities, career development opportunities, adequate peer support and a clearly defined scope of role. Conversely, job satisfaction scores decreased the more people agreed there was a lack of leadership and they had insufficient resources to provide quality care.
Conclusion
Cancer nurses are critical to the delivery of cancer care however, the workforce is challenged with shortages. This study provides an understanding of the Australian cancer nursing workforce characteristics, their roles and activities, and highlights important considerations for retaining nurses in the profession. We identified individual, organizational, and systemic factors that contribute to job satisfaction and outline strategies to address these. Findings can be used to address and prioritize workforce challenges.

Published: May 2023

Abstract
Neural crest-derived ecto-mesenchymal stem cells (EMSCs), as the progenitor cells of odontogenic stem cells, may be the suitable seed cell for regenerative dentistry. p75NTR, as the neural crest stem cell marker, plays a crucial role during the teeth development of EMSCs. Nevertheless, the interaction networks p75NTR connecting with odonto/osteogenic differentiation and mineralization are still poorly studied. Circular RNAs (circRNAs) regulate life processes mainly by performing as a competitive endogenous RNA (ceRNA) to prevent the process that microRNAs (miRNAs) bind with their target mRNAs. But the roles of p75NTR-related circRNAs in EMSCs are largely unknown. We used circRNA-seq to examine the differentially expressed circRNAs between WT and p75NTR (-/-) EMSCs and three of them were selected for qRT-PCR verification. GO, KEGG and Reactome enrichment analyses showed that differentially expressed circRNAs interact with cell proliferation, locomotory behavior, cell differentiation and are mainly involved in Wnt, JAK/STAT, Hippo and TGF-β signaling pathways. Then, CCK8, transwell assay and ALP staining assay were performed to verify the result of enrichment analyses. Then, the circRNA-miRNA interaction networks were constructed by using bioinformatics analysis. A new circRNA, mmu_circ_0001380 and mmu_circ_0013536 were selected to predict potential target miRNAs. Besides, with TargetScan, we noticed that these three circRNAs may influence the expression of DSPP and RUNX2 and qRT-PCR was performed for verification. Therefore, these three circRNAs are inclined to be vital in developing EMSCs and be novel core molecules for the further understanding of odontogenesis related to p75NTR.

Abstract

Background: To compare the diagnostic value of 120-kV with conventional 96-kV Cone-Beam CT (CBCT) of the temporal bone after cochlear implant (CI) surgery.Methods: This retrospective study included CBCT scans after CI surgery between 06/17 and 01/18. CBCT allowed examinations with 96-kV or 120-kV; other parameters were the same. Two radiologists independently evaluated following criteria on 5-point Likert scales: osseous spiral lamina, inner and outer cochlear wall, semi-circular canals, mastoid trabecular structure, overall image quality, metal and motion artefacts, depiction of intracochlear electrode position and visualisation of single electrode contacts. Effective radiation dose was assessed.Results: Seventy-five patients (females, n = 39 [52.0%], mean age, 55.8 ± 16.5 years) were scanned with 96-kV (n = 32, 42.7%) and 120-kV (n = 43, 57.3%) protocols including CI models from three vendors (vendor A n = 7; vendor B n = 43; vendor C n = 25). Overall image quality, depiction of anatomical structures, and electrode position were rated significantly better in 120-kV images compared to 96-kV (all p < = 0.018). Anatomical structures and electrode position were rated significantly better in 120-kV CBCT for CI models from vendor A and C, while 120-kV did not provide improved image quality in CI models from vendor B. Radiation doses were significantly higher for 120-kV scans compared to 96-kV (0.15 vs. 0.08 mSv, p < 0.001).Conclusions: 120-kV and 96-kV CBCT provide good diagnostic images for the postoperative CI evaluation. While 120-kV showed improved depiction of temporal bone and CI electrode position compared to 96-kV in most CI models, the 120-kV protocol should be chosen wisely due to a substantially higher radiation exposure.

Abstract
SBAS InSAR has long been used in the mining surface deformation monitoring, and its research has been widely concerned by researchers worldwide. For the problem of unsatisfactory accuracy of SBAS InSAR-monitored mining surface deformation results, It proposed a new corrected model by integrating SBAS InSAR and logistic function. First, the time series deformation results in mining areas were obtained by SBAS InSAR, and the variation law of differences between SBAS InSAR- and leveling-monitored deformation values were counted. Then, the corrected model was established by the logistic linear regression analysis function, and solved using the Levenberg-Marquardt algorithm. Finally, the corrected high-accuracy time series deformation results in the mining area were obtained. A mining area in Shandong Province of China was taken as the research object and the practical application effect of the proposed corrected model was verified. Results showed that logistic function could relatively accurately describe the variation law of the differences and the corrected results were significantly better than SBAS InSAR-monitored results, and the RMSEs of corrected results improved by 33%-58%. The accuracy of SBAS InSAR-monitored mining surface deformation was effectively improved.

Abstract
Purpose: To compare the efficacy and safety of micropercutaneous nephrolithotomy (MPCNL) and flexible ureteroscopy (FURS) in the treatment of single upper ureteral calculi larger than 10 mm.
Methods: This is a retrospective study that incorporates medical record review with an outcomes management database.163 patients who underwent MPCNL and 137 patients who underwent FURS were identiﬁed from January 2017 to December 2021. Demographic data,operation time,hospitalization time,stone free rate and complication rate were collected and analyzed.
Results: Preoperative general data of sex, age, BMI,serum creatinine, time of stone existence,stone hardness,stone diameter preoperative hydronephrosis and preoperative infection of the MPCNL group have no statistically significant difference with that of the FURS group.All of the MPCNL or FURS surgeries in two groups were successfully completed, with no one returned to opening or other surgery.Patients treated by MPCNL had significantly shorter operation time (49.6 vs 72.4 minutes;P＜0.001) but longer hospitalization time (9.1 vs 3.9days;P＜0.001) than those treated by FURS.Stone free rate in the MPCNL group was better than that of the FURS group(90.8% vs 71.5%;P＜0.001). There was no statistically significant difference in complication rate between two groups(13.5% vs 15.3%;P＝0.741).
Conclusion: Both MPCNL and FURS are effective and safe surgical options for patients with single upper ureteral calculi larger than 10 mm. FURS had shorter hospitalization time than MPCNL,but with a relatively lower stone free rate and longer operation time.There was no significant differences between two groups in complication rate.

Abstract
Background The causes of obsessive-compulsive disorder (OCD) remain unknown. Gene-searching efforts are well underway, but the identification of environmental risk factors is at least as important and should be a priority because some of them may be amenable to prevention or early intervention strategies. Genetically informative studies, particularly those employing the discordant monozygotic (MZ) twin design, are ideally suited to study environmental risk factors. This protocol paper describes the study rationale, aims, and methods of OCDTWIN, an open cohort of MZ twin pairs who are discordant for the diagnosis of OCD.Methods OCDTWIN has two broad aims. In Aim 1, we are recruiting MZ twin pairs from across Sweden, conducting thorough clinical assessments, and building a biobank of biological specimens, including blood, saliva, urine, stool, hair, nails, and multimodal brain imaging. A wealth of early life exposures (e.g., perinatal variables, health-related information, psychosocial stressors) are available through linkage with the nationwide registers and the Swedish Twin Registry. Blood spots stored in the Swedish phenylketonuria (PKU) biobank will be available to extract DNA, proteins, and metabolites, providing an invaluable source of biomaterial taken at birth. In Aim 2, we will perform within-pair comparisons of discordant MZ twins, which will allow us to isolate unique environmental risk factors that are in the causal pathway to OCD, while strictly controlling for genetic and early shared environmental influences. To date (May 2023), 43 pairs of twins (21 discordant for OCD) have been recruited.Discussion OCDTWIN hopes to generate unique insights into environmental risk factors that are in the causal pathway to OCD, some of which have the potential of being actionable targets.
