Using Early Exits for Fast Inference in Automatic Modulation Classification

Automatic modulation classification (AMC) plays a critical role in wireless communications by autonomously classifying signals transmitted over the radio spectrum. Deep learning (DL) techniques are increasingly being used for AMC due to their ability to extract complex wireless signal features. However, DL models are computationally intensive and incur high inference latencies. This paper proposes the application of early exiting (EE) techniques for DL models used for AMC to accelerate inference. We present and analyze four early exiting architectures and a customized multi-branch training algorithm for this problem. Through extensive experimentation, we show that signals with moderate to high signal-to-noise ratios (SNRs) are easier to classify, do not require deep architectures, and can therefore leverage the proposed EE architectures. Our experimental results demonstrate that EE techniques can significantly reduce the inference speed of deep neural networks without sacrificing classification accuracy. We also thoroughly study the trade-off between classification accuracy and inference time when using these architectures. To the best of our knowledge, this work represents the first attempt to apply early exiting methods to AMC, providing a foundation for future research in this area

catena-Poly[diquinolinium [[diaqua­cobaltate(II)]-μ-cyclo­tetra­phosphato] hexa­hydrate]

The cyclo­tetra­phosphate anion, [P4O12]4−, forms the title complex with cobalt(II) and quinolinium, {(C9H8N)2[Co(P4O12)(H2O)2]·6H2O}n. In the complex anion, the CoII ion, lying on an inversion center, is surrounded by four phosphate O atoms and two water mol­ecules in a slightly distorted octa­hedral geometry. The crystal structure consists of anionic ribbons of formula {[Co(P4O12)(H2O)2]2−}n extending along [100]. A network of O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds consolidates the crystal packing

MRSA induced pulmonary-renal syndrome

We present a rare case of pulmonary-renal syndrome secondary to recurrent MRSA spondylodiscitis. The mechanism of involvement of each organ system is unique. The organs, lung and kidneys, have been affected by different pathologic processes that were induced, we think, by the chronic MRSA infection

Fetal lung volume and pulmonary artery resistance index for prediction of neonatal respiratory distress syndrome

Background: As gestational age grows, the risk of newborn respiratory distress syndrome (RDS) diminishes because the lungs are the last foetal organs to properly mature. While neonatal RDS does not just occur following preterm births, it is often thought of as a disorder of premature babies. This study sought to determine how prenatal lung capacity and foetal Pulmonary artery resistance index (PARI) affected the probability that newborn RDS would occur. Methods: This prospective observational study was carried out on 200 pregnant women aged 20-35 years, with gestational age between 36-40 weeks and singleton pregnancy. According to neonatal outcome the patients were classified into two groups: group A: 26 cases with noenatal RDS and group B: 174 cases without neonatal RDS. All patients were subjected to 2D ultrasonography and 3D ultrasonography. Results: Fetal lung volume (FLV) is a significant predictor of neonatal RDS (AUC: 0.820, p <0.001), at a cut off value of ≤35, with 88.5% sensitivity and 68.4% specificity. PARI is not a significant predictor of neonatal RDS. 1 and 5 min Apgar score were significantly lower in neonates who developed RDS and those who didn’t (p<0.001). Conclusions: 3D FLV and estimated fetal weight measurement using ultrasonography may be a reliable non-invasive indicator of the incidence of newborn RDS in preterm pregnancies when the risk of RDS progression is present. FLV is a significant predictor for neonatal RDS at a cutoff for ≤35 cm3 with sensitivity 88.5% and specificity 68.4%

Design, synthesis, molecular modeling and biological evaluation of novel diaryl heterocyclic analogs as potential selective cyclooxygenase-2 (COX-2) inhibitors

AbstractNew series of 3,4-diaryl-2-thioxoimidazolidin-4-ones and 3-alkylthio-4,5-diaryl-4H-1,2,4-triazoles were designed, synthesized and evaluated for their activity as anti-inflammatory agents. Compounds 20, 21, 23 and 34 are highly selective inhibitors of COX-2 enzyme at a concentration of 100mM relative to celecoxib, the standard reference. (±)-3-(4-Phenoxy-phenyl)-5-phenyl-2-thioxoimidazolidin-4-ones 23 exhibited the most active anti-inflammatory agent

Ammonia vs. Lactic Acid in Predicting Positivity of Microbial Culture in Sepsis: The ALPS Pilot Study

Objective: The use of serum ammonia as a novel marker for sepsis compared to lactic acid levels in intensive care unit (ICU) patients. Design and Interventions: Single arm, prospective clinical trial to collect arterial blood samples from patients with sepsis. Serial ammonia and lactic acid levels were sent every six hours for a total of three days. Measurements and results: Compare mean levels of ammonia and lactic acid in terms of diagnosing sepsis and patient outcome, including length of stay and mortality. A total of 30 patients were enrolled in the pilot study. On admission, mean ammonia level was 35.7 μmol/L and lactic acid was 3.06 mmole/L. Ammonia levels checked at the end of day 2 (ammonia 2-4) and the beginning of day 3 (ammonia 3-1) were higher in patients who had a microbial culture-proven sepsis (p-values 0.029 and 0.002, respectively) compared to those without culture-positive sepsis. Ammonia levels did predict a longer hospital stay; ammonia level of more than 40 μmol/L had a mean hospital stay of 17.6 days vs. patients with normal levels who had a mean hospital stay of 9.62 days (p-value 0.0082). Conclusion: Elevated ammonia level can be a novel biomarker for sepsis, comparable to conventional markers. Ammonia levels have a prognostic utility as elevated levels were associated with longer hospital stay

Imaging immunoassay in negative: Surface-­‐catalysed chemiluminescence for the detection of pregnancy hormones in artificial saliva

A novel and rapid (45min), quantitative chemiluminescence-based, surface immunoassay is reported for the quantitative detection of progesterone and œstriol in artificial saliva. The detection limits for these pregnancy hormones are 2.3 and 2.5 pg mL-1, respectively. The assay is based on the use of ferrocene- tagged, monoclonal antibodies immobilised on a surface, so that the oxidised ferricenium catalyses the reaction between luminol and hydrogen peroxide. The immunoassay is performed in negative, such that increasing the antigen concentration gives rise to decreasing light intensity that is observed, and is unaffected by antibody orientation on the surface. This affords a method of calibration that is readily translated to pregnancy hormone detection in a primary point-of-care environment. Biomolecules with similar structures to these pregnancy hormones found in saliva are demonstrated not to interfere with the immunoassay

Actividad antiinflamatoria de dos variedades de aceite de semillas de calabaza en un modelo de artritis adyuvante en ratas

The aim of the present research was to evaluate the anti-inflammatory activity of pumpkin seed oils (PSOs) of an Egyptian and European variety, in a rat model of adjuvant arthritis. Edema thickness, plasma tumor necrosis factor-α (TNF-α) and erythrocyte sedimentation rate (ESR) were determined as inflammatory biomarkers while malondialdehyde (MDA) and total antioxidant capacity (TAC) were assessed as indicative of oxidative stress. Chromosomal aberration, sperm shape abnormalities, and DNA fragmentations are cytogenetic parameters which aid in tracing inflammatory and oxidative activity. Phenolic contents and β-carotene were determined in PSOs. The results showed elevated ESR, plasma TNF-α, plasma MDA, liver cellular DNA fragmentation, bone marrow chromosomal aberration, sperm shape abnormalities with a reduction in plasma TAC and body weight gain in an adjuvant arthritis control compared to a healthy control. Administration of low and high doses of either Egyptian or European PSO improved all the aforementioned parameters with variable degrees.El objetivo de la presente investigación fue evaluar la actividad antiinflamatoria de aceites de calabaza (PSOs) de variedades egipcia y europea, en un modelo de rata con artritis adyuvante.
