Efficiency of dynamical decoupling sequences in the presence of pulse errors

For a generic dynamical decoupling sequence employing a single-axis control, we study its efficiency in the presence of small errors in the direction of the controlling pulses. In the case that the corresponding ideal dynamical decoupling sequence produces sufficiently good results, the impact of the errors is found to scale as {xi}{sup 2}, with negligible first-order effect, where {xi} is the dispersion of the random errors. This analytical prediction is numerically tested in a model in which the environment is modeled by one qubit coupled to a quantum kicked rotator in chaotic motion. In this model, with periodic pulses applied to the qubit in the environment, it is found numerically that periodic bang-bang control may outperform Uhrig dynamical decoupling.
Search on a Hypercubic Lattice using a Quantum Random Walk: I. d>2

Random walks describe diffusion processes, where movement at every time step is restricted to only the neighbouring locations. We construct a quantum random walk algorithm, based on discretisation of the Dirac evolution operator inspired by staggered lattice fermions. We use it to investigate the spatial search problem, i.e. finding a marked vertex on a $d$-dimensional hypercubic lattice. The restriction on movement hardly matters for $d>2$, and scaling behaviour close to Grover's optimal algorithm (which has no restriction on movement) can be achieved. Using numerical simulations, we optimise the proportionality constants of the scaling behaviour, and demonstrate the approach to that for Grover's algorithm (equivalent to the mean field theory or the $d\to\infty$ limit). In particular, the scaling behaviour for $d=3$ is only about 25% higher than the optimal $d\to\infty$ value.
Relaxation of high-current electron beams and the modulational instability

The modulational instability of the plasma noise in resonance with high-current high-energy beams in a plasma becomes important when these beams relax. The short-wavelength transfer of the oscillations caused by such an instability appreciably protracts the process of the collective relaxation of the beam. We derive and solve in this paper equations describing the dynamics of the relaxation under such conditions. We study the cases of relativistic and non-relativistic beam energies.
On the realizability of relativistic acoustic geometry under a generalized perturbation scheme for axisymmetric matter flow onto black holes

We propose a novel linear perturbation scheme to study the stability properties of the stationary transonic integral solutions for axisymmetric matter flow around astrophysical black holes for the Schwarzschild as well as for rotating Rindler space time. We discuss the emergence of the relativistic acoustic geometry as a consequence of such stability analysis. Our work thus makes a crucial connection between two apparently non-overlapping fields of research - the accretion astrophysics and the analogue gravity phenomena.
Limits on second‐order non‐Gaussianity from Minkowski functionals of WMAP 7‐year data

We analyse non-Gaussianity (NG) due to the primordial bispectrum and trispectrum using cosmic microwave background temperature maps of WMAP 7-year data. We first apply the perturbative formulae of Minkowski functionals (MFs) up to second-order NG derived by Matsubara, which enable us to give limits on cubic NG parametrized with τNL and gNL as well as various types of quadratic NG parametrized with fNL. We find no signature of primordial NG in WMAP 7-year data, but give constraints on the local-type, equilateral-type and orthogonal-type fNL, , and , respectively, and τNL/104 = −7.6 ± 8.7 and gNL/105 = −1.9 ± 6.4. We also find that these constraints are consistent with the limits from skewness and kurtosis parameters which characterize the perturbative corrections of MFs.
Impact of Different KDIGO Criteria on Clinical Outcomes for Early Identification of Acute Kidney Injury after Non-Cardiac Surgery

The Kidney Disease Improving Global Outcomes (KDIGO) guidelines are currently used in acute kidney injury (AKI) diagnosis and include both serum creatinine (SCR) and urine output (UO) criteria. Currently, many AKI-related studies have inconsistently defined AKI, which possibly affects the comparison of their results. Therefore, we hypothesized that the different criteria in the KDIGO guidelines vary in measuring the incidence of AKI and its association with clinical outcomes. We retrospectively analyzed that data of patients admitted to the intensive care unit after non-cardiac surgery in 2019. Three different criteria used to define AKI were included: UOmean, mean UO < 0.5 mL/kg/h over time; UOcont, hourly UO < 0.5 mL/kg/h over time; or SCR, KDIGO guidelines SCR criteria. A total of 777 patients were included, and the incidence of UOmean-AKI was 33.1%, the incidence of UOcont-AKI was 7.9%, and the incidence of SCR-AKI was 2.0%. There were differences in the length of ICU stay and hospital stay between AKI and non-AKI patients under different criteria. We found differences in the incidence and clinical outcomes of AKI after non-cardiac surgery when using different KDIGO criteria.
Observation of Third Harmonic Generation in Two-Dimensional MoS2 Semiconductor Using Terahertz Free-Electron Laser

This study presents the third harmonic generation (THG) in two-dimensional MoS2 deposited on Si/SiO2 substrate. Intense terahertz pulses from a free-electron laser were used as pump. The pump central frequency is 3.5 THz, and the THG peak is observed around 10 THz. The THG intensity dependence on excitation density follows the $I_{3 \omega} \propto I_{\omega}^{3}$ relation which further confirms the THG.
Effects of Intraoperative Opioid Administration on Postoperative Pain and Pain Threshold: A Randomized Controlled Study

Fentanyl and short-acting remifentanil are often used in combination. We evaluated the effect of intraoperative opioid administration on postoperative pain and pain thresholds when the two drugs were used. Patients who underwent gynecological laparoscopic surgery were randomly assigned into two groups (15 patients each) to receive either sufficient (group A) or minimum (group B) fentanyl (maximum estimated effect site concentration: A: 7.86 ng/mL, B: 1.5 ng/mL). The estimated effect site concentration at the end of surgery was adjusted to the same level (1 ng/mL). Patients in both groups also received continuous intravenous remifentanil during surgery. The primary outcome was the pressure pain threshold, as evaluated by a pressure algometer 3 h postoperatively. The pressure pain threshold at 3 h postoperatively was 51.1% (95% CI: [44.4–57.8]) in group A and 56.6% [49.5–63.6] in group B, assuming a preoperative value of 100% (p = 0.298). There were no significant differences in pressure pain threshold and numeric rating scale scores between the groups after surgery. The pain threshold decreased significantly in both groups at 3 h postoperatively compared to preoperative values, and recovered at 24 h. Co-administration of both opioids caused hyperalgesia regardless of fentanyl dose.
Application Of The Co-Creation Concept Of Written Batik Design For Fashion Design In The Teenage And Current Market Segment

Entering the era of globalization, business development in any field has challenges, with so many varied Batik market segments, it is necessary to develop a more appropriate design by involving consumers to provide ideas or, more precisely, holding a co-creation of batik motifs by involving consumers from several market segments. Through the use of the co-creation concept, the purpose of this research is to transform a written batik product design based on local knowledge into a fashion design for the youth and contemporary market segment. This concept is a concept that gives consumers the freedom of ideas to create designs or revise existing designs according to the wishes of consumers. However, within limits provided by the Kudubanjar Batik Center as a producer, so with innovation and creation, new values will emerge in the design. Fashion for the teen and contemporary market segments because currently consumers tend to be able to play a role in the desired fashion design process. The method used for this design is to conduct FGD research to explore alternative fashion design creations. From the results of the FGD, a design sketch is prepared, which is then used as a guide for co-creation. Besides that, consumers are also free to design according to their wishes and current design trends. Based on the results of the research that has been done, there are eight fashion designs with the creation and innovation of batik motif designs designed based on local wisdom.
Spatial Filtering and Model Interpretation for Spatial Durbin Models

Spatial Filter for spatial autoregressive models like the spatial Durbin Model have seen a great interest in the recent literature. Pace et al. (2011) show that the spatial filtering methods developed by Griffith (2000) have desireable estimation properties for some parameters associated with spatial autoregessive models. However, spatial filtering faces two conceptual weaknesses: First the estimated parameters lack in general, and especially for the Spatial Durbin Model a proper interpretation. Second, there exists an inherent tradeoff between the estimator bias and its efficiency, depending on the spectrum of the used spatial weight matrix. This paper tackles both problems by introducing a new four step estimation procedure based on the eigenvectors of the spatial weight matrix. This new estimation procedure estimates all parameters of interest in a Spatial Durbin model and thus allows for a proper model interpretation. Additionally the estimation procedure's efficiency is only marginally influenced by the number of added eigenvectors, which allows us to use approximatly 95% of the available eigenvectors. By using Monte Carlo Simulations we observe that the estimaton procedure has a lower (or equal) bias and smaller (or equal) sample variance as the corresponding Maximum Likelihood estimator based on normality.
THz emission spectroscopy of interlayer phonons in MoSe2

Terahertz (THz) time-domain emission spectroscopy was performed on layered 2H-MoSe2. The THz emission shows coherent phonon signals in addition to the usual single cycle THz pulse. Fourier analysis of the highly damped oscillatory response shows low frequency peaks below 1 THz (33 cm−1 which we attribute to infrared active interlayer shear and breathing modes.
WIRELESS SENSING AND COMMUNICATION
DESIGN FOR THE INTERNET OF THINGS: AN
ANALYSIS

The Internet is evolving from a network that is centred on people to one that is centred on objects. By 2020, it is predicted that 50 billion things will be connected to the Internet. However, maintaining compatibility across diverse Internet things, such as handheld mobile devices, wireless connectivity, and Radio Frequency Authentication, becomes incredibly challenging as a result of this shift. Numerous little devices are now being used in various facets of daily life thanks to advancements in wireless information and electronic equipment. These devices are capable of sensing, computing, and communicating. Common parts include integrated CPUs, several intelligent systems, and low-power antennas. A WSN, which is necessary for sensing and monitoring environmental factors, is built using these sensors. In addition to WSNs, the idea of the Internet of Things (IoT) is gaining popularity. According to this definition, the IoT is the connection of identifiable objects to the internet for the purpose of detection and monitoring.
Gravitational waves from p-form inflation

Recently it was shown that an inflationary background can be realized by any p-form field non-minimally coupled to gravity. In this paper, we study gravitational waves generated during p-form inflation. Even though the background evolution is identical to that in conventional scalar field inflation, the behavior of gravitational waves is different in p-form inflation. In particular, we find that the propagation speed of gravitational waves differs from unity in 2- and 3-form inflationary models. We point out that the squared speed becomes negative in the large field models. The small field models are free from pathologies and the correction to the spectrum of gravitational waves turns out to be very small.
Evaluation of the 8th Edition AJCC Staging System for the Clinical Staging of Pancreatic Cancer

Simple Summary The 8th edition of the AJCC staging system for pancreatic cancer has been validated for pathological staging; however, its suitability for clinical staging is still uncertain. Clinical staging is important for pancreatic cancer because surgical resection is not suitable for most patients. We validated the prognostic performance and suitability of the current staging system for clinical staging. In our analysis using a prospectively collected pancreatic cancer cohort database, survival difference was not shown between stage IB and IIA, which were divided by the new size-based T3 criterion. Among the patients who received surgery, the pathological stage was more advanced than the clinical stage in 57.3%, mostly due to a false-negative lymph node in clinical staging. These findings suggest that the 8th edition AJCC staging system is not validated for clinical staging and separate criteria more suitable for clinical staging should be established. Abstract The 8th edition of the American Joint Committee on Cancer (AJCC) staging system for pancreatic cancer (PC) has been validated for pathological staging; however, its significance for clinical staging remains uncertain. We validated the prognostic performance and suitability of the current staging system for the clinical staging of PC. We identified 1043 patients from our PC registry who were staged by imaging according to the 8th edition staging system and conducted analysis, including overall survival (OS) comparison. Gradual prognostic stratification according to stage hierarchy yielded significant OS differences between stage groups, except between stage I and II (p = 0.193). A substage comparison revealed no survival differences between IB (T2N0) and IIA (T3N0), which were divided by the T3 criterion only (p = 0.278). A higher N stage had significantly shorter OS than a lower N stage (all pairwise p < 0.05). However, among the 150 patients who received upfront surgery, the pathological stage was more advanced than the clinical stage in 86 (57.3%), mostly due to a false-negative cN0 (70.9%). Our results suggest that the new definition of T3 and the number-based N criteria in the 8th edition AJCC staging system may be not adequate for clinical staging. Establishing separate criteria more suitable for clinical staging should be considered.
Core-Shell Leaky-Wave Lens Antenna for 150GHz Fly’s Eye Communication Systems

This work presents a novel lens antenna architecture based on a core-shell lens design with a leaky-wave in-packaged antenna at 150GHz. An electrically small core lens made of dense dielectric material is used to enhance the radiation of the in-packaged antenna. A low-loss dielectric shell lens with electrically large dimensions is then added to provide high directivity. A microstrip feeding network for connection to a 150GHz chipset is then also discussed. The proposed lens antenna provides good quality patterns with aperture efficiencies above 80% over a bandwidth of 20%.
Matrix effects on the magnetic properties of γ-Fe2O3 nanoparticles dispersed in a multiblock copolymer

The magnetic properties of γ-Fe2O3 ferrimagnetic nanoparticles embedded in a multiblock poly(ether-ester) copolymer have been investigated by static magnetization and ferromagnetic resonance (FMR) measurements at two different dispersion states. Significant variation of the magnetic response is identified below T≈120K, most pronounced in the marked resonance field shift of the FMR spectra, independently of the dispersion state of the nanocomposites. This behavior correlates favorably with the dynamic relaxation of the copolymer, indicating a matrix freezing effect that is attributed to the magnetoelastic coupling of the oxide nanoparticles with the surrounding polymer. At low temperatures, the dc magnetization and FMR measurements vary considerably for the two nanocomposites, indicating essential differences in their ground state, related to the different morphology of the samples and the concomitant variation of interparticle interactions.
Improving Higgs plus Jets analyses through Fox{Wolfram Moments

improvement with respect to the standard analysis based on an analysis of the tagging jet correlations. In addition, we show that replacing a jet veto by a Fox-Wolfram moment analysis of the extra jet radiation almost doubles the signal-to-background ratio. Finally, we show that this improvement can also be achieved based on a modied denition of the Fox{Wolfram moments which avoids introducing a new physical scale below the factorization scale. This modication can reduce the impact of theory uncertainties on the Higgs rate and couplings measurements.
The role of FAST in pulsar timing arrays

The Five-hundred-meter Aperture Spherical radio Telescope (FAST) will become one of the world-leading telescopes for pulsar timing array (PTA) research. The primary goals for PTAs are to detect (and subsequently study) ultra-low-frequency gravitational waves, to develop a pulsar-based time standard and to improve solar system planetary ephemerides. FAST will have the sensitivity to observe known pulsars with significantly improved signal-to-noise ratios and will discover a large number of currently unknown pulsars. We describe how FAST will contribute to PTA research and show that jitter- and timing-noise will be the limiting noise processes for FAST data sets. Jitter noise will limit the timing precision achievable over data spans of a few years while timing noise will limit the precision achievable over many years.
Chemotherapy, transarterial chemoembolization, and nephrectomy combined treated one giant renal cell carcinoma (T3aN1M1) associated with Xp11.2/TFE3: A case report

BACKGROUND Renal cell carcinoma (RCC) with Xp11.2 translocation/TFE3 gene fusion is a rare and distinct subtype of RCC that is classified under tumors with translocation of the microphthalmia-associated transcriptional factor. CASE SUMMARY We report an adult case of Xp11.2 translocation advanced RCC with metastasis (T3aN1M1), after targeted treatment, alcohol ablation, and transarterial chemoembolization, who eventually underwent successful surgical excision. No recurrence or transfer was seen within one year, and the survival period was more than 3 years. A review of the relevant literature was conducted to improve our understanding of the pathogenesis, epidemiology, clinical manifestations, diagnosis, differential diagnosis, treatment, and other aspects of the disease. CONCLUSION Transarterial chemoembolization and ablation did not achieve the desired tumor reduction in this patient, but had a significant effect on reducing intraoperative bleeding and inhibiting tumor activity.
Reproducibility and Validity of a Semi-Quantitative Food Frequency Questionnaire for Assessing Dietary Intake of Vegetarians and Omnivores in Harbin, China

This study aims to evaluate the reproducibility and validity of a semi-quantitative food frequency questionnaire (SQFFQ) developed for vegetarians and omnivores in Harbin, China. Participants (36 vegetarians and 64 omnivores) administered SQFFQ at baseline (SQFFQ1) and six months later (SQFFQ2) to assess the reproducibility. The 24 h recalls (24 HRs) for three consecutive days were completed between the administrations of two SQFFQs to determine the validity. For reproducibility, Pearson correlation coefficients between SQFFQ1 and SQFFQ2 for vegetarians and omnivores were 0.45~0.88 and 0.44~0.84, respectively. For validity, unadjusted Pearson correlation coefficients were 0.46~0.83 with an average of 0.63 and 0.43~0.86 with an average of 0.61, respectively; energy-adjusted Pearson correlation coefficients were 0.43~0.82 with an average of 0.61 and 0.40~0.85 with an average of 0.59, respectively. Majority of the correlation coefficients for food groups and macronutrients decreased or remained unchanged after energy adjustment. Furthermore, all correlations were statistically significant (p < 0.05). Bland–Altman plots also showed reasonably acceptable agreement between the two methods. In conclusion, the SQFFQ developed in this study has reasonably acceptable reproducibility and validity.
Sexual violence and adverse reproductive health outcomes among youth females in North Shoa zone, Oromia, Ethiopia: A community-based cross-sectional study

Objective: The aim of this study is to assess the magnitude of sexual violence, its adverse reproductive health outcomes, and associated factors among female youth in the Northern Shoa zone, Oromia region, Ethiopia. Methods: A community-based cross-sectional study design was employed among 590 female youth from 1 December to 30 January 2021. A multi-stage sampling technique and a pretested structured interviewer-administered questionnaire were used. The data were entered into EpiData version 3.1 and then transferred to SPSS 23 for analysis. Descriptive statistical analysis was done, and an association between an outcome variable and independent variables was examined in logistic regression models. Results: According to the study, the respective rates of sexual violence and harmful sexual reproductive consequences were 20.7% and 11.9%. Sexual violence was significantly associated with alcohol consumption (adjusted odds ratio = 2.549, 95% confidence interval = (1.548, 4.195)) and childhood exposure to inter-parental violence (adjusted odds ratio = 1.66, 95% confidence interval = (1.002, 2.888)). Rural childhood residence (adjusted odds ratio = 0.037, 95% confidence interval = (0.007, 0.192)), fathers with college degrees (adjusted odds ratio = 0.037, 95% confidence interval = (0.013, 0.106)), and readiness for first sex (adjusted odds ratio = 0.073, 95% confidence interval = (0.028, 0.189)) were all independent predictors of adverse reproductive health outcomes. Conclusion: In this study, young females frequently experience sexual violence and poor reproductive health outcomes. Alcohol consumption and having experienced parental conflict as a child were found to be risk factors for sexual violence, while residing contracts during childhood, the father’s level of education, and willingness to engage in the first sexual encounter were linked to adverse reproductive health outcomes.
