Tracking error estimation is of great importance in global navigation satellite system (GNSS) receivers. Any inaccurate estimation for tracking error will decrease the signal tracking ability of signal tracking loops and the accuracies of position fixing, velocity determination, and timing. Tracking error estimation can be done by traditional discriminator, or Kalman filter-based pre-filter. The pre-filter can be divided into two categories: coherent and non-coherent. This paper focuses on the performance improvements of non-coherent pre-filter...

Estrogen deficiency following menopausal provokes alveolar bone loss, remodeling and inflammation. Eugenol is a phenolic compound with wide dental applications and anti-inflammatory properties. In the present study, the potential protective role of eugenol against alveolar bone deformities was investigated in an ovariectomized (OVX) rodent model. Two doses of eugenol (2.5 and 5 mg/kg/d) were administered to OVX animals for 12 weeks. In Serum, markers of bone metabolism and pro-inflammatory cytokines were estimated using ELISA...

Drug dilution (MIC) and disk diffusion (DIA) are the 2 most common antimicrobial susceptibility assays used by hospitals and clinics to determine an unknown pathogen's susceptibility to various antibiotics. Since only one assay is commonly used, it is important that the 2 assays give similar results. Calibration of the DIA assay to the MIC assay is typically done using the error-rate bounded method, which selects DIA breakpoints that minimize the observed discrepancies between the 2 assays. In 2000, Craig proposed a model-based approach that specifically models the measurement error and rounding processes of each assay, the underlying pathogen distribution, and the true monotonic relationship between the 2 assays...

Background The gold standard therapy for full-thickness macular holes (FTMH) is vitrectomy (PPV) with peeling of the internal limiting membrane (ILM), gas tamponade of the vitreous cavity and postoperative face-down positioning. Nevertheless, eyes with large macular holes (> 400 µm) and surgical failures remain difficult to manage. Recently, ILM transplantation (ILM-TX) techniques were developed with acceptable results, advocating different mechanisms of hole closure: in such a setting, the ILM could serve as a scaffold for neuronal tissue in the pedicle ILM flap technique or the ILM could induce a contraction of the FTMH rims through shrinking of a folded ILM plug...

Implantation of artificial intraocular lenses (IOL) after cataract removal today represents the standard of care in the field of anterior segment surgery. In refractive lens exchange cases the natural lens is replaced by an IOL to correct different types of refractive situations. In the majority of the operations the refractive result is satisfying with only few deviations from target refraction.But daily practice reveals some outliers from the intended corrections with the need for further refractive enhancements, respectively...

This study examines young volleyball players' learning of increasingly complex attack gestures. The main purpose of the study was to examine the predictive role of a cognitive variable, working memory capacity (or "M capacity"), in the acquisition and development of motor skills in a structured sport. Pascual-Leone's theory of constructive operators (TCO) was used as a framework; it defines working memory capacity as the maximum number of schemes that can be simultaneously activated by attentional resources...

BACKGROUND: Bipolar Disorder (BD) cannot be reliably distinguished from Major Depressive Disorder (MDD) until the first manic or hypomanic episode. Consequently, many patients with BD are treated with antidepressants without mood stabilizers, a strategy that is often ineffective and carries a risk of inducing a manic episode. We previously reported reduced cortical thickness in right precuneus, right caudal middle-frontal cortex and left inferior parietal cortex in BD compared with MDD...

Estimation of the attenuation is important in medical ultrasound not only for correct time-gain compensation but also for tissue characterization. In this paper, the feasibility of a new method for attenuation estimation is tested. The proposed method estimates the attenuation by repeatedly solving the forward wave propagation problem and matching the simulated signals to the measured ones. This approach allows avoiding common assumptions made by other methodologies and potentially allows to account and correct for other acoustic effects that may bias the attenuation estimate...

Hydraulic fracturing (HF) has allowed for the utilization of previously unattainable shale oil and gas (O&G) resources. After HF is complete, the waters used to increase the facies' permeability return uphole as wastewaters. When these waters return to the surface, they are characterized by complex organic and inorganic chemistry, and can pose a health risk if not handled correctly. Therefore, these waters must be treated or disposed of properly. However, the variability of these waters' chemical composition over time is poorly understood and likely limits the applicability of their reuse...

Surgical correction of complex foot and ankle deformities secondary to Charcot neuroarthropathy remains a significant surgical challenge. New technological advancements in hardware have allowed for the use of augmented fixation techniques in midfoot deformity correction, including the use of indication-specific locking plates and beaming techniques that offer enhanced stability. Severe hindfoot deformity management can employ the use of internal fixation, including intramedullary hindfoot nails and circular external fixation frames for limb salvage...

Hallux-abducto-valgus or "bunion" surgery is one of the most common surgical procedures for the foot and ankle specialist. As our understanding of the hallux-abducto-valgus deformity has grown, it is becoming clear that the anatomic CORA of the deformity may lie at the tarsometatarsal joint. There is also the component of the 3-dimensional nature of the deformity that may be best addressed at this CORA. With these issues in mind, it was necessary to address the shortcomings of the traditional Lapidus procedure and progress toward more consistent, instrumented steps that could address the 3-dimensional nature of the deformity...

Limb deformity correction has been widely discussed in orthopedic literature with an increasing interest in technologically based surgical strategies. However, principles described by Ilizarov and Paley still form the basis of these newly developing surgical systems. The recent advances and increased use of computers and mobile devices in the medical arena, along with the application of dynamic hexapod external fixation, have allowed for easier and more convenient strategies, leading to a greater outreach and more confidence in the newer surgeon when faced with addressing a patient with a limb deformity...

Knowledge of dental anatomy is of great importance in the practice of dentistry, especially in oral rehabilitation, because without this knowledge, professional practice is not possible. Dental carving plays a major role in training dental students as it develops their manual dexterity. This randomized controlled trial aimed to evaluate the influence of didactic-theoretical reinforcement on the theoretical and practical knowledge of dental anatomy of preclinical students by examining the quality of the anatomical restorations performed by these students before and after a didactic-theoretical reinforcement...

Adverse intrauterine environment may induce adult disease in offspring, but the mechanisms are not well understood. It is reported that fresh embryo transfer (ET) in assisted reproductive technology presents extra-high maternal estradiol (E2) and prenatal high E2 exposure increases the risk of organ disorders in later life. We found male newborns and children of fresh ET showed increased fasting insulin and the homeostasis model of assessment for insulin resistance index (HOMA-IR). Prenatal high E2 exposed (HE) male mice grew heavier than control and developed insulin resistance, they also showed increased food intake with enhanced orexigenic hypothalamic neuropeptide Y (NPY) expression...
