Asymptotic Diffusion Analysis of Multi-Server Retrial Queue with Hyper-Exponential Service

Field: Mathematics (Physical Sciences)

A multi-server retrial queue with a hyper-exponential service time is considered in this paper. The study is performed by the method of asymptotic diffusion analysis under the condition of long delay in orbit. On the basis of the constructed diffusion process, we obtain approximations of stationary probability distributions of the number of customers in orbit and the number of busy servers. Using simulations and numerical analysis, we estimate the accuracy and applicability area of the obtained approximations.

Cardiorespiratory Fitness in University Level Volleyball Players and its Correlation with Body Fat

Field: Health Professions (Health Sciences)

Abstract Introduction. The present study was aimed to compare the cardiorespiratory fitness levels (VO 2 max) between university level male and female volleyball players and to find its correlation with percentage body fat. Material and Methods. In the present cross-sectional study, male and female volleyball players (n = 15 each) aged 18-25 years were randomly selected from Teerthanker Mahaveer University, Moradabad, India. An equal number of sedentary individuals were also selected who did not indulge in any vigorous physical activity or training. Body height, body weight, body mass index (BMI), % lean body mass of players and sedentary individuals were recorded using standard methods. Percentage body fat was calculated using the sum of four skinfolds and VO 2 max was recorded using Queen’s college step test. Data were analysed using SPSS software version 20.0. Unpaired t-test was used for comparison between players and sedentary individuals and two-way ANOVA was used to examine interaction of status (active players and sedentary individuals) and gender on VO 2 max. Results. Players had higher mean values for % lean body mass and VO 2 max. Statistically, highly significant differences (p < 0.05) were observed between male and female players for all variables except BMI. Players had better cardiorespiratory fitness (VO2max) as compared to their sedentary counterparts. Conclusions. Significant differences exist between players and sedentary individuals for percentage body fat and percentage lean body mass. Cardiorespiratory fitness of players is negatively correlated with percentage body fat. Players have higher VO2max as compared to their sedentary counterparts.
Killing of <i>S</i>. Typhimurium by total IgG, IgM and IgA from HIV-uninfected and HIV-infected sera.

Field: Immunology and Microbiology (Life Sciences)

<p>Log growth phase <i>S</i>. Typhimurium D23580 was added to a mixture of the purified antibodies and 75% BRS. The log<sub>10</sub> proportion of the starting number of bacteria remaining after 180 minutes was determined on LB agar. To obtain total antibody of each isotype (IgG, IgM and IgA), serum was incubated sequentially with combinations of human IgA and IgM affinity matrices and protein G affinity matrix to remove IgA, IgM and IgG respectively. Sera used were HIV-uninfected (HIV-ve bactericidal, n = 3), HIV-infected bactericidal (HIV+ve bactericidal, n = 4) and HIV-infected inhibitory (HIV+ve inhibitory, n = 5) sera. Each line represents killing by purified total IgG, IgM or IgA antibodies from one serum. Data shown are from a single representative experiment, where each of the three independent experiments was performed in technical triplicates.</p>
Remote System for Monitoring Animal Models With Single-Metabolite Bio-Nano-Sensors

Field: Engineering (Physical Sciences)

A novel system for remote monitoring of metabolism in an animal model is proposed in this paper. The system is obtained by integrating bio-nano-sensors to detect single- metabolites, an electrochemical front-end made with off-the-shelf components, a radio frequency communication sub-system, and an antenna of new design. The system has been calibrated and tested for continuous monitoring of four different metabolites: glucose, lactate, glutamate, and adenosine triphosphate. Tests using animal models (mice) have been conducted to investigate tissue inflammation induced by the implanted bio-nano-sensors. These tests confirm that our system is suitable and reliable for remote monitoring of single-metabolites in experiments with animal models.
Forms of Inorganic Phosphorus in Medium Black Soils of Chambal Commanded Area

Field: Agricultural and Biological Sciences (Life Sciences)

The inorganic soil phosphorus was fractionated as Al, Fe and Ca-bound phosphorus and also their occluded forms. Ca-bound phosphorus was found to represent maximum amount, on an average 79.5 and 78.9 per cent of inorganic phosphorus in grey soils and brown soils respectively. Ah bound phosphorus and occluded Al-bound phosphorus represented 9.8 and 10.9 per cent of inorganic phosphorus in grey soils and brown soils respectively. Fe-bound phosphorus represented the least amount of inorganic phosphorus. Fe-bound phosphorus and occluded Fe-bound phosphorus were found to contain 0.94, 0.86 and 10.35, 9.87 per cent of inorganic phosphorus in the above two soils respectively. No significant correlation was obtained between Olsen phosphorus and Ca-bound phosphorus in both the soils.
Sp1 Deacetylation Induced by Phorbol Ester Recruits p300 To Activate 12(S)-Lipoxygenase Gene Transcription

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

We previous reported that Sp1 recruits c-Jun to the promoter of the 12(S)-lipoxygenase gene in 12-myristate 13-acetate-treated cells. We now show that Sp1 that recruited HDAC1 to the Sp1/cJun complex was constitutively acetylated when cells were exposed to phorbol 12-myristate 13-acetate (PMA) (3 h). Prolonged stimulation of the cells with PMA (9 h), however, caused the dissociation of histone deacetylase 1 (HDAC1) and the deacetylation of Sp1, with the latter being able to recruit p300 that in turn caused the acetylation and dissociation of histone 3, thus enhancing the expression of 12(S)-lipoxygenase. We also overexpressed an Sp1 mutant (K703/A, lacking acetylation sites) in the cell and found that cells recruited more p300 and expressed more 12(S)-lipoxygenase. Taken together, our results indicated that Sp1 recruits HDAC1 together with c-Jun to the gene promoter, followed by deacetylation of Sp1 upon PMA treatment. p300 is then recruited to the gene promoter through the interaction with deacetylated Sp1 to acetylate histone 3, leading to the enhancement of the expression of 12(S)-lipoxygenase.
Unidirectional plasmons propagation

Field: Physics and Astronomy (Physical Sciences)

To excite surface plasmons efficiently, the surface plasmons must receive energy from incident light, in which conservation of momentum must be satisfied between light propagating in free space and the surface plasmons. However, the momentum of light propagating through air never matches the momentum of surface plasmons. One solution is to use a grating as a plasmon coupler. This allows the momentum of the incident light to match the momentum of the surface plasmons for efficient surface plasmon excitation. However, in this method, the direction of propagation of surface plasmons cannot be controlled due to the diffraction.
Isolation and characterization of Saccharomyces cerevisiae mutants resistant to Calcofluor white

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Calcofluor is a fluorochrome that exhibits antifungal activity and a high affinity for yeast cell wall chitin. We isolated Saccharomyces cerevisiae mutants resistant to Calcofluor. The resistance segregated in a Mendelian fashion and behaved as a recessive character in all the mutants analyzed. Five loci were defined by complementation analysis. The abnormally thick septa between mother and daughter cells caused by Calcofluor in wild-type cells were absent in the mutants. The Calcofluor-binding capacity, observed by fluorescence microscopy, in a S. cerevisiae wild-type cells during alpha-factor treatment was also absent in some mutants and reduced in others. Staining of cell walls with wheat germ agglutinin-fluorescein complex indicated that the chitin uniformly distributed over the whole cell wall in vegetative or in alpha-factor-treated cells was almost absent in three of the mutants and reduced in the two others. Cell wall analysis evidenced a five- to ninefold reduction in the amount of chitin in mutants compared with that in the wild-type strain. The total amounts of cell wall mannan and beta-glucan in wild-type and mutant strains were similar; however, the percentage of beta-glucan that remained insoluble after alkali extraction was considerably reduced in mutant cells. The susceptibilities of the mutants and the wild-type strains to a cell wall enzymic lytic complex were rather similar. The in vitro levels of chitin synthase 2 detected in all mutants were similar to that in the wild type. The significance of these results is discussed in connection with the mechanism of chitin synthesis and cell wall morphogenesis in S. cerevisiae.
Obesity, Sleep Apnea, and the Cardiorespiratory Effects of Leptin

Field: Medicine (Health Sciences)

I. Introduction In the past, adipose tissue was thought of simply as a passive depot for the storage of excess calories. Now, studies have revealed that fat tissue is an active endocrine organ with high metabolic activity. Indeed, excess fat has been shown to synthesize and secrete biologically active molecules that mediate complex respiratory and cardiovascular processes. One such molecule is leptin. In this chapter, we review the link between leptin and cardiorespiratory effects in obstructive sleep apnea (OSA). We discuss the neuromodulators of appetite and metabolism, with particular emphasis on leptin, and review the concept of leptin resistance. We present data that support a stimulatory role for leptin in respiratory function and a protective role for leptin in the development of pathologic cardiac hypertrophy and congestive heart failure (CHF). Finally, we close this chapter with a discussion of how leptin is linked to OSA, obesity hypoventilation syndrome (OHS), and conditions of chronic hypoxia.

Web Services based on PROLOG and XML

Field: Computer Science (Physical Sciences)

Abstract. This paper describes how the deductive power of PROLOG can be made available across the Internet using standardized Web service technologies. This facilitates the use of PROLOG as a component of distributed information systems and in many new application scenarios. Since a lot of information available on the Internet is nowadays XML based and since Web service technologies use XML based encodings, it is both necessary and useful to be able to process XML documents in PROLOG itself. To make this possible, a new package for SWI– PROLOG called X2P is introduced, making available to PROLOG many of the XML processing facilities of the Libxml2 library, which is a very up–to–date and efficient implementation of most of the current XML related standards. 1
Supplementary Primary Frequency Control Through Deep Reinforcement Learning Algorithms

Field: Computer Science (Physical Sciences)

This work presents the implementation of deep reinforcement learning (DRL) agents as supplementary primary frequency controllers. To achieve this, the primary frequency regulation problem is formulated in a DRL framework, where an actor-critic algorithm, for continuous actions space, is used to change the frequency reference of traditional governors. By modifying this reference, the DRL agent effectively reduces the magnitude of the frequency nadir and rate of change of frequency, thereby enhancing the power grid frequency response. Two DRL algorithms including Deep Deterministic Policy Gradient (DDPG) and Twin Delayed DDPG (TD3) are employed for the frequency regulation. The supplementary control using these two algorithms is tested on a 14-bus, 5-machine test system. The results show that the frequency stability of the grid can be improved by using DRL algorithms as supplementary controllers in the primary frequency regulation.
[Frequent growth disorders in puberty and adolescence].

Field: Medicine (Health Sciences)

About 50% of our patients with concern about their actual or final height are adolescents (girls greater than 11 years, boys greater than 13 years). Growth data of 103 adolescent patients (70 boys, 33 girls) seen in 1988/89 are analysed. 85% of the patients (90% of the boys) complained of short stature (length less than 3rd centile) whereas tall stature (height greater than 97th centile) was more frequently concerning girls (9 out of 16 patients). Genetic short stature and constitutional delay of growth and adolescence (CDGA) were most often diagnosed in short stature patients. When retardation of physical maturation is a major concern in patients with CDGA, treatment with a low dose of sex steroids leads to an acceleration of growth and pubertal development. This advancement of maturation is important for reducing the psychosocial difficulties of the concerned adolescents. Constitutional tall stature was the most frequent diagnosis in our tall adolescent patients. If predicted final height is above 185 cm for girls or 200 cm for boys the administration of height dose sex steroids (ethinylo-estraidol or conjugated oestrogen for girls, testosteron for boys) for height reduction can be tried, since a reduction in height between 3.5 cm and 7.9 cm has been reported for girls and similar data exists for boys. Nevertheless a cautious approach must be advocated for the administration of oestrogens because possible long term hazards can not yet be excluded.
A modified Krylov subspace model reduction method based on the Chebyshev polynomials

Field: Mathematics (Physical Sciences)

In this paper, we present a modified Krylov subspace model reduction method for linear time invariable systems based on the Chebyshev polynomials. Noting the structure of the Chebyshev polynomial coefficient matrices, which are calculated approximately via the Chebyshev polynomial expansion of the state variable, we employ Krylov subspace to construct decent projection matrices. A reduced order system is produced in two-sided projection framework by combining the time and the frequency domain analysis. Two numerical examples are used to illustrate the efficiency of the method.
Atraumatic acute forearm compartment syndrome due to systemic heparin

Field: Medicine (Health Sciences)

A 65-year-old woman was admitted to the hospital for acute heart failure exacerbation. Her history was notable for insulin-dependent diabetes mellitus and mitral valve regurgitation requiring mechanical mitral valve replacement. Found to have mitral paravalvular leak, the patient’s home warfarin was held and heparin infusion was started in preparation for valvular surgery.

Eleven days after starting heparin infusion, the patient awoke with severe right forearm pain that worsened throughout the day and by the afternoon had developed decreased sensation at the small finger. Visually, the right forearm had mild swelling and ecchymoses, but was without evidence of traumatic injury, venipuncture, erythema, or fluctuance. On forearm examination, the patient was remarkably tender to palpation over both dorsal and volar compartments, endorsed pain with passive extension of the fingers, and both dorsal and volar compartments were rigid to palpation. The distal compartments of the hand remained soft and non-tender …

Technical Note—A Note on Relaxations of the Choice Network Revenue Management Dynamic Program

Field: Decision Sciences (Social Sciences)

In recent years, several approximation methods have been proposed for the choice network revenue management problem. These approximation methods are proposed because the dynamic programming formulation of the choice network revenue management problem is intractable even for moderately sized instances. In this paper, we consider three approximation methods that obtain upper bounds on the value function, namely, the choice deterministic linear program (CDLP), the affine approximation (AF), and the piecewise-linear approximation (PL). It is known that the piecewise-linear approximation bound is tighter than the affine bound, which in turn is tighter than CDLP. In this paper, we prove bounds on how much the affine and piecewise-linear approximations can tighten CDLP. We show (i) the gap between the AF and CDLP bounds is at most a factor of [Formula: see text], where [Formula: see text] are the resource capacities, and (ii) the gap between the piecewise-linear and CDLP bounds is within a factor of 2. Moreover, we show that these gaps are essentially tight. Our results hold for any discrete-choice model and do not involve any asymptotic scaling. Our results are surprising because calculating the AF bound is NP-hard and CDLP is tractable for a single-segment multinomial logit model; our result implies that if a firm has all resource capacities of 100, the gap between the two bounds, however, is at most 1.01.

566: DESCRIPTIVE ANALYSIS OF OBSTETRIC PATIENTS WITH PULMONARY EMBOLISM AT A SINGLE TERTIARY CENTER

Field: Medicine (Health Sciences)

Introduction: Obstetric patients with pulmonary embolism (PE) are at higher risk of severe maternal morbidity and mortality. There is limited data validating current PE scoring systems in the obstetric population. We performed a descriptive study comparing the clinical characteristics and maternal and neonatal outcomes of the PERT consults in all of our female patients in reproductive age, by their pregnancy status. Methods: We identified all female patients in reproductive age (18 to 55) between 1/2019 to 5/2022, and divided by pregnancy status. Electronic medical records were used to collect clinical characteristics and treatment modalities. The primary outcome was survival at 30 days. Secondary outcomes included echocardiogram and CTA findings, admission vital signs, BOVA score procedural and neonatal outcomes. Univariable analysis was performed to compare characteristics and primary outcomes. Results: A total of 106 PERT consults were reported. 6 patients were pregnant. At the time of PE diagnosis the mean gestational age was 23w3d (SD). Two patients were delivered with 1 maternal death. Obstetric patients were younger than non-pregnant patients (33.8 vs. 41.9, p= 0.06). There was no statistical difference in right ventricular (RV) strain by CT (46% vs, p= 0.85), initial heart rate (102 vs. 111, p= 0.28), systolic blood pressure (102 vs. 119, p= 0.08), elevated troponin (50% vs. 61%, p= 0.59), or presence of massive PE (16.7% vs. 16%, p= 0.97). Standard Bova score points were also similar (2.2 vs. 2.1, p= 0.78) corresponding to a grade of 1, low risk. There were more low risk consults in the pregnant group (33.3% vs. 5%, p= 0.007). On initial TTE, there was no difference in RV dilation, function, RVSP, or TAPSE between the groups. Each group also had similar of rates transfer to ICU and interventions on arrival. Survival at 30 days was lower in the pregnant group (83.3% vs. 98%, p= 0.04). Conclusions: Despite similar demographic, hemodynamic, and TTE characteristics between all patients in reproductive age, our study suggest that obstetric patients with PE are at a higher risk of death. Indicating that traditional triage and management guidelines for patients with PE lack reproducibility in the obstetric population. New risk factors need to be identified for outcome predictors in obstetric patients.
A historical and contemporary consideration of the diet of the reef manta ray (Manta alfredi) from the Great Barrier Reef, Australia

Field: Agricultural and Biological Sciences (Life Sciences)

The preserved stomach contents from the manta ray, collected in 1935, that provided the basis for the 2009 taxonomic resurrection of the species Manta alfredi, were examined. The majority of the material comprised calanoid copepods (61.7%) and trypanorhynch cestodes (34.6%), with minor contributions by arrow worms, a barnacle larva and a nematode. Comparison of the size-frequency distributions of stomach contents with that of zooplankton from the Great Barrier Reef region suggest that this manta ray preferentially ingested large copepods, or that the filter mechanism used to extract prey from the water was selective for prey items over 0.8 mm in length. This is the first description of the diet of M. alfredi from stomach contents, and is consistent with previous inferences about what this species consumes.
