- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

- The ozone profile records of a large number of limb and occultation satellite instruments are widely used to address several key questions in ozone research. Further progress in some domains depends on a more detailed understanding of these data sets, especially of their long-term stability and their mutual consistency. To this end, we made a systematic assessment of 14 limb and occultation sounders that, together, provide more than three decades of global ozone profile measurements. In particular, we considered the latest operational Level-2 records by SAGE II, SAGE III, HALOE, UARS MLS, Aura MLS, POAM II, POAM III, OSIRIS, SMR, GOMOS, MIPAS, SCIAMACHY, ACE-FTS and MAESTRO. Central to our work is a consistent and robust analysis of the comparisons against the ground-based ozonesonde and stratospheric ozone lidar networks. It allowed us to investigate, from the troposphere up to the stratopause, the following main aspects of satellite data quality: long-term stability, overall bias and short-term variability, together with their dependence on geophysical parameters and profile representation. In addition, it permitted us to quantify the overall consistency between the ozone profilers. Generally, we found that between 20 and 40km the satellite ozone measurement biases are smaller than ±5%, the short-term variabilities are less than 5-12% and the drifts are at most ±5%decade-1 (or even ±3%decade-1 for a few records). The agreement with ground-based data degrades somewhat towards the stratopause and especially towards the tropopause where natural variability and low ozone abundances impede a more precise analysis. In part of the stratosphere a few records deviate from the preceding general conclusions; we identified biases of 10% and more (POAM II and SCIAMACHY), markedly higher single-profile variability (SMR and SCIAMACHY) and significant long-term drifts (SCIAMACHY, OSIRIS, HALOE and possibly GOMOS and SMR as well). Furthermore, we reflected on the repercussions of our findings for the construction, analysis and interpretation of merged data records. Most notably, the discrepancies between several recent ozone profile trend assessments can be mostly explained by instrumental drift. This clearly demonstrates the need for systematic comprehensive multi-instrument comparison analyses.

- Background: The effect on type 2 diabetes mellitus (T2DM) when adipose tissue is removed is controversial. This study aimed to evaluate and compare the effect of the abdominoplasty and bariatric surgery on glycemic control in patients with T2DM. Methods: Patients with T2DM undergoing abdominoplasty for cosmesis were studied (n=25). Subjects were 36.91.3 years with a preoperative body mass index (BMI) of 40.60.5kg/m(2) and mean glycated hemoglobin (HbA1c) of 7.4%+/- 0.2%. Fifteen matched patients undergoing bariatric surgery were selected as a comparator group. Weight, BMI, waist circumference (WC), random blood glucose (RBG), and HbA1c were evaluated at baseline and 3, 6, and 12 months postsurgery. Results: By 12 months, abdominoplasty reduced weight by 5.6 +/- 0.3kg p<0.01), and HbA1c was reduced to 6.8%+/- 0.3% (p<0.01). After 12 months, bariatric surgery reduced BMI from 42.2 +/- 1kg/m(2) to 26.6 +/- 0.4kg/m(2) (p<0.01). HbA1c reduced from 7.9%+/- 0.4% to 5.5%+/- 0.2% (p<0.01). WC was similar between both groups at 3 months, although HbA1c reductions were superior after bariatric surgery. Conclusions: Reducing subcutaneous adipose tissue with abdominoplasty results in a small improvement in glycemic control in patients with T2DM. Despite equivalent WC at 3 months, bariatric surgery outperformed abdominoplasty on all metabolic parameters then and thereafter.

- Functional*Reactive Programming (FRP) is a declarative approach to modeling and building reactive systems. Priority-based FRP (P-FRP) is a formalism of FRP that guarantees real-time response. Unlike the classical preemptive model1 of real-time systems, preempted tasks in PFRP are aborted and have to restart when higher priority tasks have completed. Due to this abort-restart of nature of preemption, there is no single critical instant of release that leads to Worst-Case Response Time (WCRT) of lower priority P-FRP tasks. At this time, the only method for determining the WCRT is through an exhaustive enumeration of all release offsets of higher priority tasks between the release and deadline of the lower priority task. This makes the computational cost of WCRT dependent on the deadline of a task, and when such deadlines are large the computational costs of this technique make it infeasible even for small task sets. In this paper, we show that the release offsets of higher priority tasks have a lower and upper bound and present techniques to derive these bounds. By enumerating only those release offsets while lie within our derived bounds the number of release scenarios that have to be enumerated is significantly reduced. This leads to lower computational costs and makes determination of the WCRT in P-FRP a practically feasible proposition. © 2011 IEEE.

- Kaiabachev, Taha, Zhu [1] have presented a declarative programming paradigm called Functional Reactive Programming, which is based on behaviors and events. An improved system called P-FRP uses fixed priority scheduling for tasks. The system allows for the currently executing lower priority tasks to be rolled back to restoring the original state and allowing a higher priority task to run. These aborted tasks will restart again when no tasks of higher priority are in the queue. Since P-FRP has many applications in the real time domain it is critical to understand the time bound in which the tasks which have been aborted are guaranteed to run, and if the task set is schedulable. In this paper we provide an analysis of the unique execution paradigm of the P-FRP system and study the timing bounds using different constraint variables.1. R. Kaiabachev, W. Taha, A.

- Smart buildings promise to revolutionize the way we live. Applications ranging from climate control to fire management can have significant impact on the quality and cost of these services. However, a smart building and any technology with direct effect on the safety of its occupants must undergo extensive testing. Virtual testing by means of computer simulation can significantly reduce the cost of testing and, as a result, accelerate the development of novel applications. Unfortunately, building physically-accurate simulation codes can be labor intensive. To address this problem, we propose a framework for rapid, physically-accurate virtual testing of smart building systems. The proposed framework supports analytical modeling and simulation of both a discrete distributed system as well as the physical environment that hosts it. © 2012 Springer-Verlag Berlin Heidelberg.

- Background: In the pharmaceutical sector, tissue culture techniques for large-scale production of natural chemicals can be a less expensive alternative to large-scale synthesis. Although recent biotransformation research have used plant cell cultures to target a wide range of bioactive compounds, more compiled information and synopses are needed to better understand metabolic pathways and improve biotransformation efficiencies.Purpose: This report reviews the biochemical transformation of phenolic natural products by plant cell cultures in order to identify potential novel biotechnological approaches for ensuring more homogeneous and stable phenolic production year-round under controlled environmental conditions.Methods: Articles on the use of plant cell culture for polyphenolic and flavonoid transformations (1988 - 2021) were retrieved from SciFinder, PubMed, Scopus, and Web of Science through electronic and manual search in English. Following that, the authors chose the required papers based on the criteria they defined. The following keywords were used for the online search: biotransformation, Plant cell cultures, flavonoids, phenolics, and pharmaceutical products.Results: The initial search found a total of 96 articles. However, only 70 of them were selected as they met the inclusion criteria defined by the authors. The analysis of these studies revealed that plant tissue culture is applicable for the large-scale production of plant secondary metabolites including the phenolics, which have high therapeutic value.Conclusion: Plant tissue cultures could be employed as an efficient technique for producing secondary metabolites including phenolics. Phenolics possess a wide range of therapeutic benefits, as anti-oxidant, anti-cancer, and antiinflammatory properties. Callus culture, suspension cultures, transformation, and other procedures have been used to improve the synthesis of phenolics. Their production on a large scale is now achievable. More breakthroughs will lead to newer insights and, without a doubt, to a new era of phenolics-based pharmacological agents for the treatment of a variety of infectious and degenerative disorders.

Towards a Primitive Higher Order Calculus of Broadcasting Systems
- 2002

- Ethernet-style broadcast is a pervasive style of computer communication. In this style, the medium is a single nameless channel. Previous work on modelling such systems proposed a first order process calculus called CBS. In this paper, we propose a fundamentally different calculus called HOBS. Compared to CBS, HOBS 1) is higher order rather than first order, 2) supports dynamic subsystem encapsulation rather than static, and 3) does not require an "underlying language" to be Turing-complete. Moving to a higher order calculus is key to increasing the expressivity of the primitive calculus and alleviating the need for an underlying language. The move, however, raises the need for significantly more machinery to establish the basic properties of the new calculus. This paper develops the basic theory for HOBS and presents two example programs that illustrate programming in this language. The key technical underpinning is an adaptation of Howe's method to HOBS to prove that bisimulation is a congruence. From this result, HOBS is shown to embed the lazy λ-calculus.

- A NEW ligand of geminal cyclodiphosph(V)azane derivatives, 1,3-di-[N/-2,6-dimethoxyLl-pyrimidnylsulfanilamide12,4-di-IN/-2-quinoxalinylsulfanilamidel-2,4dichloroc- yelodiphosph(V)azane (H4L') was prepared. The ligand and its related complexes were characterized by different physicochemical techniques, namely; IR, UV vis, mass, 'H NMR, molar conductance, magnetic, solid reflectance, and thermal analysis The spectral data revealed that the ligand behaves as ionic in nature and coordinated to the metal ions via enolic-OH of sulphonamide group and pyrimidine N. The molar conductance data reveal that the complexes were electrolytes, while UV vis, solid reflectance and magnetic moment data have been shown that the complexes have octahedral geometry. The thermal behavior of the complexes was also studied. The ligand and its metal complexes showed a high to moderate antimicrobial activities against deferent strains of bacteria and fungi, also showed anticancer activity against colon carcinoma HCT116.
