A 0.96-mW dB-Linear Variable Gain Amplifier With 0.4-dB Linearity Error Over a 62.4-dB Gain Tuning Range

This letter presents a low-power dB-linear variable gain amplifier (VGA) with a small linear-in-dB error over a wide gain tuning range. An exponential current ratio is realized in the linear-in-dB control circuit based on the subthreshold I–V characteristic. The VGA is built with subthreshold common-gate transistors as current steering, accurately replicating the exponential current ratio and forming a tunable gain. Implemented in 55-nm CMOS technology, the proposed VGA occupies a compact active area of 0.011 mm2 excluding the buffer. It achieves a linear-in-dB error of 0.4 dB over a gain tuning range of 62.4 dB, corresponding to the state-of-the-art relative error of 0.6%. The proposed design shows constant 80-MHz bandwidth with a power consumption of 0.96 mW.
Qualitative Analysis of Multiple Phytochemical Compounds in Tojapride Based on UHPLC Q-Exactive Orbitrap Mass Spectrometry

Tojapride is composed of Caulis Perillae, Rhizoma Cyperi, Radix Glycyrrhizae, Citrus aurantium L. , Coptis chinensis Franch, Pericarpium Citri Reticulatae, Reynoutria japonica Houtt, Tetradium ruticarpum, and Cleistocactus sepium. It has the effects of inhibiting gastric acid and relieving pain. It is clinically used for treating gastroesophageal reflux disease. To further study the pharmacodynamic properties of Tojapride, the systematic characterization of the chemical constituents in Tojapride was investigated using ultra-performance liquid chromatography with Q-Exactive Orbitrap mass spectrometry combined with parallel reaction monitoring for the first time. Eventually, a total of 222 compounds, including flavonoids, alkaloids, and glycyrrhizic acid derivatives, were identified based on the chromatographic retention times, MS/MS2 information, and bibliography data; a total of 218 of these were reported for the first time as being present in Tojapride. This newly developed approach provides a powerful tool for extending our understanding of chemical constituents of Tojapride, which can be further extended to other TCMP composition research.
Polymorphisms of the melatonin receptor 1A (MTNR1A) gene affect sexual performance of Rasa Aragonesa rams without changing their social dominance

The aim of this study was to investigate whether a speci�c genotype of the MTNR1A gene in�uences social dominance and reproductive performance in rams. Thirty-one rams were genotyped for Rsal and Mnll polymorphism of the gene: CC (n = 19), CT (n = 5), and TT (n = 7), and GG (n = 20), GA (n = 6), or AA (n = 5), respectively. Social behavior was recorded by direct observations, and rams were tested in individual serving-capacity tests. The genotypes did not differ in the numbers of aggressions that they performed or received, and their active and passive behaviors were similar. For the Rsal and Mnll polymorphism, TT and GG rams were responsible for 54% and 56% of the total number of recorded sexual events (P < 0.05), respectively. Results of this study con�rm that the best sexual performance of rams was among those that carried certain genotypes of the MTNR1A gene, but it was not correlated with differences in social dominance.
Angular Correlation Functions for Models with Logarithmic Oscillations

There exist several theoretical motivations for primordial correlation functions (such as the power spectrum) to contain oscillations as a logarithmic function of comoving momentum k. While these features are commonly searched for in k-space, an alternative is to use angular space; that is, search for correlations between the directional vectors of observation. We develop tools to efficiently compute the angular correlations based on a stationary phase approximation and examine several example oscillations in the primordial power spectrum, bispectrum, and trispectrum. We find that logarithmically-periodic oscillations are essentially featureless and therefore difficult to detect using the standard correlator, though others might be feasible.
Projections of Future Air Quality Are Uncertain. But Which Source of Uncertainty Is Most Important?

Understanding how air pollution events may change in the future is of key importance to decision makers. Multi‐model intercomparison projects focusing on atmospheric chemistry and air quality have been performed to inform the latest IPCC assessments. Future anthropogenic emission changes have generally been the foci of such model experiments, envisaged as the dominant driver of future atmospheric composition. The latest model assessments such as AerChemMIP utilize multi‐model ensembles but also have limited individual model ensembles which permit different sources of uncertainty to be characterized. The recent study by Fiore et al. (2022, https://doi.org/10.1029/2021JD035985) specifically considers a multi‐model and multi‐member ensemble approach. It adds to the quantification of uncertainty in future projections through delineating uncertainty due to model diversity and due to internal or natural climate variability within the climate system, for mean and high PM2.5 air pollution events over the Eastern USA in the 21st century. Exploring the separate roles of internal climate variability and model diversity adds further value to the important research issue of quantifying how future anthropogenic climate change impacts air quality. Future multi‐model intercomparisons need to balance the additional knowledge gained from research into understanding multiple sources of uncertainty that can inform decision making vs. the resource costs of performing these experiments using Earth System Models with interactive chemistry.

The Enterotoxin Production and Antimicrobial Resistance of Campylobacter Strains Originating from Slaughter Animals

The pathogenicity of animal-origin Campylobacter strains, including antimicrobial resistance and enterotoxigenicity, was determined in this study. Overall, 149 Campylobacter isolates originating from cattle, swine and poultry were tested. The antimicrobial resistance profiles were examined by the diffusion disk method. The dominant resistance pattern was CIP_TET. The resistance rates for ciprofloxacin among swine, cattle and poultry isolates were 84%, 51% and 66%, respectively; for tetracycline, they were 82%, 57.1% and 76%, respectively. None of the obtained isolates was resistant to all four antimicrobials tested. The ability to produce enterotoxins was assessed by the use of a suckling mouse bioassay, with intestinal fluid accumulation as a positive result, and by CHO assay, with the elongation of cells as a positive result. The ability to produce enterotoxins was significantly higher among cattle isolates (61.2% and 71.4% positive isolates, respectively, in the bioassay and the CHO assay) than among swine (16% and 32% positive isolates, respectively) or poultry isolates (14% and 22% positive isolates, respectively). A strong positive correlation between in vitro and in vivo enterotoxicity tests was demonstrated.
WAVELETS FOR DENSITY-FUNCTIONAL THEORY AND POST-DENSITY-FUNCTIONAL-THEORY CALCULATIONS

We give a fairly comprehensive review of wavelets and of their application to density-functional theory (DFT) and to our recent application of a wavelet-based version of linear-response time-dependent DFT (LR-TD-DFT). Our intended audience is quantum chemists and theoretical solid-state and chemical physicists. Wavelets are a Fourier-transform-like approach which developed primarily in the latter half of the last century and which was rapidly adapted by engineers in the 1990s because of its advantages compared to standard Fourier transform techniques for multiresolution problems with complicated boundary conditions. High performance computing wavelet codes now also exist for DFT applications in quantum chemistry and solid-state physics, notably the BigDFT code described in this chapter. After briefly describing the basic equations of DFT and LR-TD-DFT, we discuss how they are solved in BigDFT and present new results on the small test molecule carbon monoxide to show how BigDFT results compare against those obtained with the quantum chemistry gaussian-type orbital (GTO) based code deMon2k. In general, the two programs give essentially the same orbital energies, but the wavelet basis of BigDFT converges to the basis set limit much more rapidly than does the GTO basis set of deMon2k. Wavelet-based LR-TD-DFT is still in its infancy, but our calculations confirm the feasibility of implementing LR-TD-DFT in a wavelet-based code.
Will It Cricket? Product Development and Evaluation of Cricket (Acheta domesticus) Powder Replacement in Sausage, Pasta, and Brownies

Insect powders used in food products may lower the overall quality when compared to conventional counterparts. This preliminary study was used to develop and evaluate insect-based food products and to utilize them in a future consumer test. Pork sausage, dried pasta, and chocolate brownie formulations were developed to either contain NO cricket powder (Control) or have cricket powder (CP). The products were evaluated for proximate composition and product-dependent parameters. The protein content increased in the CP pasta and brownies (p < 0.05) while no changes were found in the sausage (p > 0.05). Fat content increased in both the CP pasta and brownies while it decreased in the CP sausage (p < 0.05). The CP sausage had a higher carbohydrate content than the Control (p < 0.05). Overall, this may be attributed to cricket powder being high in protein and fat while also containing dietary fiber. Cricket powder replacement may lead to noticeable color differences by increasing green and blue coloring in sausage and pasta (p < 0.05). Changes in textural properties (p < 0.05) may be attributed to cricket powder affecting protein solubility and emulsion stability in sausage while gluten formation may be interfered with in the brownies. Overall, cricket powder replacement had improved nutritional content with minor changes in quality parameters.
Polyphenols as Potent Epigenetics Agents for Cancer

Human diseases such as cancer can be caused by aberrant epigenetic regulation. Polyphenols play a major role in mammalian epigenome regulation through mechanisms and proteins that remodel chromatin. In fruits, seeds, and vegetables, as well as food supplements, polyphenols are found. Compounds such as these ones are powerful anticancer agents and antioxidants. Gallic acid, kaempferol, curcumin, quercetin, and resveratrol, among others, have potent anti-tumor effects by helping reverse epigenetic changes associated with oncogene activation and tumor suppressor gene inactivation. The role dietary polyphenols plays in restoring epigenetic alterations in cancer cells with a particular focus on DNA methylation and histone modifications was summarized. We also discussed how these natural compounds modulate gene expression at the epigenetic level and described their molecular targets in cancer. It highlights the potential of polyphenols as an alternative therapeutic approach in cancer since they modulate epigenetic activity.
Satisfaction with Urinary Incontinence Treatments in Patients with Chronic Spinal Cord Injury

Purpose: To investigate the long-term satisfaction and complications in chronic spinal cord injury (SCI) patients after various bladder management strategies and surgical procedures for the treatment of urinary incontinence. Methods: Patients at a single institution with chronic SCI who received bladder management treatment or surgical procedure to improve urinary continence were retrospectively assessed. Thorough urological examinations and videourodynamic studies were performed. Patients were treated either through conservative approaches including medical treatment, clean intermittent catheterization (CIC), cystostomy, and indwelling urethral catheter, or through surgical procedures including detrusor botulinum toxin (Botox) injections, augmentation, ileal conduit, Kock pouch diversion, continent cystostomy, suburethral sling, and artificial urethral sphincter (AUS) implantation. The patients’ satisfaction with urinary continence improvement, causes of dissatisfaction, long-term complications, and overall satisfaction with bladder and voiding condition were assessed. Results: A total of 700 consecutive patients were enrolled in this study. High satisfaction rates were noted after detrusor Botox injection (81.1%), augmentation enterocystoplasty (91.4%), autoaugmentation (80%), Kock pouch diversion, and continent cystostomy (all 100%). Fair satisfaction rates were noted after ileal conduit diversion (66.7%), suburethral sling (64.3%), and AUS implantation (66.7%). Patients who received conservative treatment with medicines, CIC, cystostomy, or an indwelling urethral catheter all had less-satisfactory outcomes (all < 40%). Conclusion: Overall satisfaction with surgical procedures aimed to improve urinary continence in chronic SCI patients was higher than with conservative bladder management (35.4%). Appropriate surgical procedures for chronic SCI patients with neurogenic lower urinary tract dysfunction (NLUTD) and urological complications yielded satisfaction with both urinary continence improvement and with overall bladder and voiding condition.
A Physical Layer Security (PLS) approach through Address Fed Mapping Crest Factor Reduction applicable for 5G/6G signals

The privacy and security of 5G/6G infrastructures are receiving great attention together with power consumption and efficiency. Here, Physical Layer Security (PLS) is considered and a technique named Address Fed Mapping (AFM) is proposed which not only enhances the physical layer security, but also reduces the effect of high Peak to Average Power Ratio (PAPR), which results in efficiency improvement in OFDM based signals used in beyond 5G and 6G [1]. The AFM is designed based on the idea of randomly generated signals, modifying the original signal to reduce PAPR. Instead of a typical randomization algorithm, a unique key is generated based on Channel response that is known only transmitter-receiver pairs. This key is used to pick a signal and send it. It is shown that the proposed AFM technique reduces PAPR, which improves the energy efficiency of the system.
Some three-point correlation functions in the η-deformed AdS5 × S5

We compute some normalized structure constants in the η-deformed AdS5 × S5 in the framework of the semiclassical approach. This is done for the cases when the “heavy” string states are finite-size giant magnons carrying one angular momentum and for three different choices of the “light” state: primary scalar operators, dilaton operator with nonzero momentum, singlet scalar operators on higher string levels. Since the dual field theory is still unknown, the results obtained here must be considered as conjectures or as predictions from the string theory side.
Radial velocity and metallicity of the globular cluster IC4499 obtained with AAOmega

We present radial velocity and metallicity measurements for the far southern Galactic globular cluster IC 4499. We selected several hundred target red giant stars in and around the cluster from the 2MASS point source catalogue, and obtained spectra at the near-infrared calcium triplet using the AAOmega spectrograph. Observations of giants in globular clusters M4, M22 and M68 were taken to provide radial velocity and metallicity comparison objects. Based on velocity data we conclude that 43 of our targets are cluster members, by far the largest sample of IC 4499 giants spectroscopically studied.We determine the mean heliocentric radial velocity of the cluster to be 31.5 ± 0.4 km s−1, and find the most likely central velocity dispersion to be 2.5±0.5 kms−1. This leads to a dynamical mass estimate for the cluster of 93±37×103M. We are sensitive to cluster rotation down to an amplitude of ≈1 km s−1, but no evidence for cluster rotation is seen. The cluster metallicity is found to be [Fe/H] = −1.52 ± 0.12 on the Carretta–Gratton scale; this is in agreement with some earlier estimates but carries significantly higher precision. The radial velocity of the cluster, previously highly uncertain, is consistent with membership in the Monoceros tidal stream as proposed by Pe˜narrubia and co-workers, but also with a halo origin. The horizontal branch morphology of the cluster is slightly redder than average for its metallicity, but it is likely not unusually young compared to other clusters of the halo. The new constraints on the cluster kinematics and metallicity may give insight into its extremely high specific frequency of RR Lyrae stars.
Mechanical Properties of Fused Deposition Modeling of Polyetheretherketone (PEEK) and Interest for Dental Restorations: A Systematic Review

The aim of this systematic review was to determine the optimal printing parameters for the producing of fused deposition modeling (FDM) 3D-printed polyetheretherketone (PEEK) elements with mechanical properties suitable for dental restorations. Indeed, the mechanical properties are a critical prerequisite for the study of other parameters, such as physical, aesthetic and biological properties. An exhaustive electronic search was carried out in the PubMed, Embase and Web of knowledge databases to gather all the studies evaluating the influence of the printing parameters on the obtained mechanical properties of FDM 3D-printed PEEK elements were selected. Initially, the search resulted in 614 eligible papers. Independent screenings of the abstracts were performed by two authors to identify the articles related to the question. Twenty-nine studies were selected, of which eleven were further excluded after reading of the full text, and finally, eighteen articles were included in this review. The studies were difficult to compare due to the variability of the printing parameters and the types of PEEK. However, it seems interesting to use a high infill rate, a high chamber temperature close to that of the printing temperature and a heat post-treatment to obtain 3D PEEK elements presenting properties adapted to use as dental restorations. The analysis of the available literature suggested that the properties of PEEK could make it an interesting material in dental restorations to be performed with FDM additive manufacturing.
The Influence of Epidural Steroids on Postoperative Pain and Hospital Stay in Patients Having a Single-Level Lumbar Discectomy

Objective: In this study, we looked at how intra-operative epidural steroids affected postoperative pain and stay duration in patients with unilateral single-level lumbar discectomy. Material & Methods: A randomized control trial was conducted at Ayub Teaching Hospital Abbottabad. Group A (n = 30) was given intraoperative epidural methylprednisolone, while group B (n = 30) was given normal saline only. The outcome was measured between the two groups in terms of postoperative pain (visual analog scale), time of mobilization, length of hospital stay, and duration to return to work. Results: At discharge, the VAS score in group A was 0.40 compared to 2.4 in group B (p = 0.000). At 2 weeks follow-up, the mean VAS score was 1.10 in group A in contrast to 1.4 in group B (p = 0.001). Patients who received local epidural methylprednisolone were mobilized after an average of 1 day, stayed for an average of 1.16 days, and returned to work following 18.2 days, whereas patients in the control group were mobilized after an average of 1.2 days, stayed for an average of 1.86 days and returned to work following 25.9 days. An incidental Dural tear occurs in 2 cases. Conclusion: Intra-operative epidural steroid is beneficial in reducing post-operative pain, hospital stay, and time to return to work. It allows early mobilization with enhanced recovery and few complications.
Characterisation of the Galactic thick disk

Abstract Thick disks appear to be common in external large spiral galaxies and our own Milky Way also hosts one. The existence of a thick disk is possibly directly linked to the formation history of the host galaxy and if its properties is known it can constrain models of galaxy formation and help us to better understand galaxy formation and evolution. This brief review attempts to highlight some of the characteristics of the Galactic thick disk and how it relates to other stellar populations such as the thin disk and the Galactic bulge. Focus has been put on results from high-resolution spectroscopic data obtained during the last 10 to 15 years.
The Effect of Temperature on Goniastrea aspera Polyp Degradation and the Post-bleaching Resistance

Coral recovery from bleaching depends not only on the intensity and continuity of some influencing factorsbut also on the cellular condition of the coral itself. The relationship between coral recovery and bleachingcan be studied from the loss process of zooxanthellae from a polyp and the tissue profile changes. Thisresearch focused on the degradation of polyp tissue due to temperature stressors and the potential recoveryafter bleaching in artificial media. It was conducted at Coastal Eco-development Laboratory of FPIK-UNDIPJepara and natural waters of coral reef ecosystem in Southern of Panjang Island Jeparafrom April toSeptember 2021. Four levels of temperature: 40oC, 36oC, 32 oC 28 oC were used to expose the sample organisms.The objectives of this research are, therefore, to (a)investigate the effect of temperature on the zooxanthellaedensity in the polyp tissues, (b) investigate the effect of temperature on process change of polyp tissues and(c) analyze the survivability of coral after bleaching. The results show that: (a) the optimum temperatureand exposure that zooxanthellae can resist in the polyp histology of Goniastrea aspera is 36 oC for 6 hours, (b)Higher temperature and longer incubation time degrade the tissue of the Goniastrea asperapolyp, influencethe zooxanthellae release and cause coral death, (c) The recovery of the Goniastrea aspera still occurs afterpartial bleaching and (d) Coral recovery is characterized by the zooxanthellae regulation process in thepolyp tissues and reaches perfect condition and to achieve perfect arrangement after week 12.
