Statistical multiplexing in data-aware transport networks

Data traffic now represents the majority of traffic carried in transport networks. Due to the very bursty nature of users' data traffic, the aggregated traffic will be also bursty in metro networks as well as in the core. If mean data rates alone are considered in network design, the bursty nature of the traffic leads to underdimensioning the networks and could result in congestion. However, ignoring statistical multiplexing, which reduces the impact of bursts by only considering peak data rates, leads to overdimensioning and excessive costs. Guerin's equivalent bandwidth model takes into account the statistical multiplexing of aggregated variable traffic flows in an accurate and very simple way, enabling the realistic dimensioning and simulation of data-aware transport networks.
Comparison of Different Grating Structure DFB Lasers for High-speed Electro-absorption Modulated Lasers

High-speed electro-absorption modulated lasers (EMLs) with three DFB laser structures (uniform grating (UG), asymmetric quarter-wave-shifted (QWS), and partially corrugated grating (PCG)) are investigated here under 56-Gb/s NRZ signal modulation. It is known that the former UG-EML suffers from performance degradation due to the residual facet reflection (RFR) and facet phase fluctuation. PCG-EML with 300-μm long laser section, 175-μm long grating section, 100-μm long modulator section, and 10-3 front-facet reflectivity can produce about ~83.8% dynamic single-mode yield (SMY), improved average Q-value, and reduced low-frequency drop (LFD) in the modulation response. By choosing the optimal grating length for the PCG-DFB and applying an asymmetric QWS-DFB, the EMLs can maintain good staticand dynamic performances over a wide range of the linear gain coefficients.
Liens entre le sentiment d’auto-efficacité, la détresse psychologique et la parentalité chez des adultes ayant une consommation problématique

Parental self-efficacy (PSE) and the presence of psychological distress in parents with problematic substance use may help explain the relationship between substance abuse and parenting. This study, using a sample of 81 parents in treatment for substance abuse, investigates whether (1) the level of PSE correlates with the severity of substance use, the severity of psychological distress, the quality of child-rearing practices, and the parent-child relationship, and whether (2) the severity of psychological distress helps explain the relationship between PSE and child-rearing practices, as well as the relationship between PSE and the parent-child relationship. While the results did not yield any significant correlations between PSE and severity of use, results did demonstrate that PSE was significantly and positively correlated with positive parenting behaviors and warm/affectionate attitudes, but significantly and negatively correlated with feelings of depression, inconsistent discipline, and hostile/aggressive and neglectful/indifferent parenting attitudes. Psychological distress (anxiety and depression) was significantly and positively correlated with the severity of substance use (alcohol and drugs) and the presence of inconsistent discipline, but significantly and negatively correlated with insufficient supervision. Anxiety symptoms were also significantly and positively correlated with hostile/aggressive parental attitudes and neglectful/ indifferent attitudes and negatively correlated with warm/affectionate attitudes. PSE alone explains positive parenting behaviors, as well as hostile/aggressive parenting attitudes of the parent toward the child. By adding anxious feelings, the variables jointly explain the lack of supervision and the three parental attitudes variables (warm/affectionate, neglectful/indifferent, and hostile/aggressive). Finally, parent gender combined with PSE explained some of the variance in inconsistent discipline. Results suggest that other factors may explain the quality of parenting among parents with problematic alcohol and drug use. Further research in this area is needed to explore these factors.

Android-based ECG Monitoring System for Atrial Fibrillation Detection using a BITalino® ECG Sensor

Cardiac arrhythmias are disorders that affect the rate and/or rhythm of the heartbeats. The diagnosis of most arrhythmias is made through the analysis of the electrocardiogram (ECG), which consists of a graphical representation of the electrical activity of the heart. Atrial fibrillation (AF) is the most present type of arrhythmia in the world population. In this context, this work deals with the implementation of a system for automatic analysis of ECG signals aiming to identify AF episodes. The system consists of a signal acquisition step performed by an ECG sensor connected to an acquisition platform. The acquired signal is transmitted via bluetooth to a smartphone with AndroidTM operating system. The signal processing is carried out through an application developed using the IDE AndroidTM Studio. When assessed over signals from the MIT-BIH Atrial Fibrillation database, the R-wave peak detection algorithm showed mean values of sensitivity and positive predictivity of 98.99% and 95.95%, respectively. The classification model used is based on a long short-term memory (LSTM) neural network and had an average accuracy of 94.94% for identifying AF episodes.
Hybrid Sinusoidal-Pulse Charging Method for the Li-Ion Batteries in Electric Vehicle Applications Based on AC Impedance Analysis

A hybrid sinusoidal-pulse current (HSPC) charging method for the Li-ion batteries in electric vehicle applications is proposed in this paper. The HSPC charging method is based on the Li-ion battery ac-impedance spectrum analysis, while taking into account the high power requirement and system integration. The proposed HSPC method overcomes the power limitation in the sinusoidal ripple current (SRC) charging method. The charger shares the power devices in the motor inverter for hardware cost saving. Phase shifting in multiple pulse currents is employed to generate a high frequency multilevel charging current. Simulation and experimental results show that the proposed HSPC method improves the charger efficiency related to the hardware and the battery energy transfer efficiency.
SOIL LOSS ESTIMATION USING THE INTERO MODEL IN THE S1-2 WATERSHED OF THE SHIRINDAREH RIVER BASIN, IRAN

UDK 631.459(55 Shirin-Dareh Basin) Soil erosion is one of the main problems of land degradation of agricultural land, especially in the mountainous areas. This negative process is one of the key problems to the environment and water resources in Iran. Using the computer-graphic modelling, we calculated sediment yield and peak discharge of the S1-2 catchment, of the Shirin-Dareh Basin of the Caspian Sea watershed. The area characterized cold winters (the minimum of 24.4°C) and warm, dry summers (the absolute maximum air temperature of 34.6°C; the average annual precipitation of 328 mm). The coefficient of the region's permeability, S1, is calculated on 0.84. The structure of the river basin, according to water permeability, is the following: f0, poor water permeability rocks, 53%; fpp, medium permeable rocks, 41%; fp, very permeable products from rocks: 6%. The most common soil type in the studied area is Inceptisols with Calcic horizon. The river basin is under the mountain pastures (51%) and the rest (49%) is the ground without grass vegetation and plough-lands. The coefficient of the river basin planning is calculated on 0.75. The coefficient of the vegetation cover is calculated on 0.9. We calculated the soil losses from the S1-2 catchment on 20404 m3 yr-1 and the peak discharge on 209 m3s-1 (for the incidence of 100 years). The value of the Z coefficient of 0.917 indicates that the river basin belongs to the second destruction category, where the strength of the erosion process is high. With this study we provided new information about the recent state of the sediment yield of the S1-2 catchment, of the Shirin- Dareh Basin in the North Khorasan province of Iran in formats that can simplify the management in the watersheds, demonstrating the possibility of Soil Loss Estimation using the IntErO Model.
3D SURVEYING AND FORMAL ANALYSIS OF A STRUCTURAL BAY OF A GOTHIC APSE

Abstract. In recent years, the development of massive data capture techniques such as Terrestrial Laser Scanner (TLS) have made it possible to develop new procedures to evaluate architectural heritage with a high level of accuracy. The study proposes a workflow to identify formal anomalies in the main elements that form a structural bay of the apse of the Cathedral of Girona, studying arches, vaults, buttresses and pillars. The methodology is based on different two-dimensional and three-dimensional procedures, and the database obtained that could help in future research to relate the results with the different construction phases and being applicable to other constructions of similar typology.
Immunohistochemical Analysis of Postburn Scars following Treatment Using Dermal Substitutes

Background Post-burn hypertrophic scars commonly occur after burns. Studies that compare dermal substitutes with other treatment methods are insufficient. The purpose was to analyze the histopathological differences in hypertrophic burn scars after Matriderm®+split-thickness skin graft (STSG) and compare with AlloDerm®+STSG, STSG, full-thickness skin graft (FTSG), and normal skin. Methods Samples of unburned, normal skin and deep 2nd or 3rd degree burns were obtained from patients who experienced a burn injury in the past to at least 6 months before biopsy, which was performed between 2011 and 2012. All subjects received >6 months of treatment before the biopsy. Intervention groups were normal (63), STSG (28), FTSG (6), Matriderm® (11), and AlloDerm® (18). Immunohistochemical analyses of elastin, collagen I, collagen III, cluster of differentiation 31 (CD31), smooth muscle actin (α-SMA), and laminin from scar and control tissues were performed and compared. Results α-SMA vascular quantity and vessel width, stromal CD31, and basement membrane laminin expression were not significantly different between normal and intervention groups. Matriderm® group showed no significant difference in elastin, collagen III, stromal CD31 and α-SMA, CD31 vessel width, stromal α-SMA, vessel quantity and width, and laminin length compared to the normal group, meaning they were not significantly different from the normal skin traits. Conclusion Dermal substitutes may be an optimal alternative to address the cosmetic and functional limitations posed by other treatment methods.
Pendeteksian Data Pencilan dan Pengamatan Berpengaruh pada Beberapa Kasus Data Menggunakan Metode Diagnostik

Abstract –– Outlier is an observation which can disturb the process of data analysis. It also could be seen as unusual observation. It causes the violation of normality error assumption in regression analysis, so that it should be detected using diagnostic method. Generally, there are several cases of outlier such as upper outlier, lower outlier, outlier occur near the center of data and upper-lower outlier. Each of those cases gives different effect to linear regression model parameter estimates. Because the unusual observation may be detected as outlier, high leverage point or influential observation. Based on the result, outlier and influential observation give significant effect toward intercept, slope, R 2 and s 2 . Keywords –– Regression, Outliers, Influential Observation, Diagnostic Abstrak –– Pencilan merupakan suatu pengamatan yang keberadaannya dapat menggangu proses analisis data. Pencilan menyebabkan asumsi kenormalan galat dalam analisis regresi tidak terpenuhi, sehingga perlu dilakukan pendeteksian keberadaan pencilan ini menggunakan metode diagnostik. Secara umum, terdapat beberapa kasus pencilan, di antaranya pencilan atas, pencilan bawah, pencilan yang mendekati pusat data serta pencilan atas-bawah. Masing-masing dari kasus pencilan tersebut memberikan pengaruh yang berbeda-beda terhadap pendugaan parameter dalam model regresi linier. Karena bisa jadi pencilan tersebut terdeteksi sebagai outlier , high leverage point maupun pengamatan berpengaruh. Berdasarkan hasil yang diperoleh, pencilan dan pengamatan berpengaruh memberikan pengaruh yang signifikan terhadap perubahan nilai intercept , slope , R 2 maupun s 2 . Kata Kunci –– Regresi, Pencilan, Pengamatan berpengaruh, Diagnostik
Is the World Running Out of Oil

As Mark Twain said, prophecies are always difficult to make, that's why nobody can say precisely how much oil there is in the world and which is yet to be discovered, for how long will last the oil we already know about and where it is, how much will we be able to exploit what we have and what is there to discover, for how long will the oil last, for how long we will need it, if we already went beyond the maximum peak of production and discoveries etc. We can only analyze the data we have, make calculations, predictions and assumptions on the basis of what has been in the past, and what it is in the present, to hope or, on the contrary, to prepare ourselves for the worst. But we can't know for certain. So we try in the following to do it, without claiming that we know the sure answer to the question that is on the lips of all humanity. Further can be found: an analysis on the oil reserves in the world, starting from the reserves discovered and put into service (as they were declared), reserves discovered and unexploited yet, reserves proven, but still undiscovered and forecasts, by the experts in the field with regard to future discoveries.
Reproductive Isolating Mechanisms and Speciation

179 DOI: 10.37398/JSR.2022. 660119 Abstract: Isolating mechanisms are those mechanisms or factors which alone or in combination prevent interbreeding between different species/populations and thus prevent gene flow between species which is essential for maintaining their integrity. These are genetically conditioned barriers for exchange of genes between Mendelian populations which are intrinsic to the organisms themselves. There are different types of isolating mechanisms: Geographical (spatial) isolation operating between allopatric populations/species and reproductive isolation operating between sympatric species/populations. There are different kinds of reproductive isolating mechanism operating in animal and plant species. Speciation (cladogenesis) is defined as origin of new species by splitting of pre-existing ones. During the process of speciation, the diverging populations accumulate genetic changes through the action of mutations, recombinations, natural selection, random genetic drift, migration and other evolutionary forces which lead to the origin and development of reproductive isolating mechanisms which are important and considered prerequisite for the process of speciation or cladogenesis. Thus due to the origin and development of reproductive isolating mechanisms, the new species are created and maintained as independent units. The well developed reproductive isolation prevents interbreeding and consequently gene flow between different species. In this article, different types of isolating mechanisms are defined and a few examples from Drosophila are given which show that origin and development of reproductive isolating mechanisms are considered prerequisite for the process of speciation. Further, the modes of speciation are also briefly summarized.
Perspective on the Use of Innovative Surveillance Strategies Implemented for COVID-19 to Prevent Mosquito-Borne Disease Emergence in French Polynesia

In French Polynesia, following the emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in March 2020, several control measures were implemented to prevent virus spread, including a population lockdown and the interruption of international air traffic. SARS-CoV-2 local transmission rapidly stopped, and circulation of dengue virus serotypes 1 and 2, the only arboviruses being detected at that time, decreased. After the borders re-opened, a surveillance strategy consisting of the testing by SARS-CoV-2 RT-PCR of travelers entering French Polynesia, and isolating those with ongoing infection, was implemented. This strategy proved efficient to limit the introduction of SARS-CoV-2, and should be considered to prevent the importation of other pathogens, including mosquito-borne viruses, in geographically isolated areas such as French Polynesia.
Complication Avoidance in Surgical Management of Vertebral Column Tumors

The surgical management of spinal tumors has grown increasingly complex as treatment algorithms for both primary bone tumors of the spine and metastatic spinal disease have evolved in response to novel surgical techniques, rising complication rates, and additional data concerning adjunct therapies. In this review, we discuss actionable interventions for improved patient safety in the operative care for spinal tumors. Strategies for complication avoidance in the preoperative, intraoperative, and postoperative settings are discussed for approach-related morbidities, intraoperative hemorrhage, wound healing complications, cerebrospinal fluid (CSF) leak, thromboembolism, and failure of instrumentation and fusion. These strategies center on themes such as pre-operative imaging review and medical optimization, surgical dissection informed by meticulous attention to anatomic boundaries, and fastidious wound closure followed by thorough post-operative care.

Effects of face velocity, cross-draft velocity and interventions on the performance of a benchtop enclosing hood

“Effects of Face Velocity, Cross-Draft Velocity and Interventions on the Performance of A Benchtop Enclosing Hood” Xinjian He In industry, benchtop enclosing hoods are critical n protecting workers from airborne contaminants, but there is little research published about industrial enclosing hoods. Almost all hood research has been done on la b ratory fume hoods. A tracer gas method was used to study the performa nce of a single benchtop enclosing hood tested inside a 9 ft high, 12 ft wide and 40 ft long wind tunnel. Freon134a concentrations were measured on an anthropomet rically scaled, heated, breathing manikin holding a source between its hand s while standing at the enclosing hood’s face. Samples were taken at the nose ( Cnose), mouth (Cmouth), inlet of the wind tunnel (Cambient ), downstream of the wind tunnel ( Cdownstream) and the exhaust duct (Cduct). Each location was sampled at 0.15 LPM for 20 minutes. The work was divided into two studies, each having a complete factorial design and two replicates of each treatment combina tion. Study-I tested the effects of hood face velocity at five levels (111, 140, 170, 2 0 and 229 fpm) and wind tunnel cross-draft velocity at five levels (14, 26, 36, 46 and 57 fpm) on the plain enclosing hood performance. Study-II determined the effects o f different interventions added to the face of the same enclosing hood. The results showed that hood face velocity, wind t unnel cross-draft velocity and different interventions had significant effects on the concentrations at Cnose and Cmouth. Flanges, cowls, and most other interventions fail ed to consistently reduce exposures and often exacerbated them. However, the customized sash reduced exposures to nearly zero. It is also found that hig her face velocity and cross-draft velocity were associated with lower Cnose and Cmouth .
A Hardware-Software Processor Architecture using Pipeline Stalls for Leakage Power Management

In recent years, power consumption has become a critical design concern for many VLSI systems. Nowhere is this truer than for portable, battery-operated applications, where power consumption has perhaps superseded speed and area as the overriding implementation constraint. But since last few years as the greater emphasis is put on miniaturization, in future technologies, the problem of subthreshold leakage power in CMOS circuits will grow in significance. The leakage current is exponentially dependent on the value of the threshold voltage such that if the threshold voltage is reduced (as it will be in the future technologies), the leakage current registers an exponential increase. Responding to this challenge, several low power techniques at levels ranging from technology to architecture have been proposed to reduce both dynamic and static power for processors and make them more energy-efficient. Some of these techniques can be applied to hardware whereas others are software based techniques. In this thesis, we propose a combined hardware-software technique which will potentially show considerable leakage energy reduction when power-performance trade-offs are made in higher-leakage technologies. A simple method to reduce the power consumption in a processor is to slow down the clock frequency. The dynamic power reduces in proportion to the frequeny reduction. However, the leakage power remains the same. Because a computing task will require the same number of clock cycles it will now take more time. The leakage energy will therefore increase, although the dynamic energy will remain the same. It is the reduction of leakage power and energy that is targeted in the present work. The main idea introduced and investigated is that the power-performance trade-off is accomplished by inserting empty(no-op) cycles while the clock rate is kept unchanged. The hardware units are especially designed to save leakage power while processing a no-op instruction. As an illustration, the hardware of a five-stage pipeline RISC processor is redesigned to reduce power consumption of the no-op cycles using sleep modes. This largely eliminates the leakage in those cycles. The expected result is that as more empty cycles are inserted, the performance would drop similar to the conventional clock frequency reduction. However, the computing task that now takes more cycles has only a marginal increase in the leakage energy. In addition, the empty cycles may eliminate many of the pipeline hazards and thus reduce the performance penalty. In this work, power supply for the active(i.e., non-empty)cycles is not changed and that aspect is left for the future investigation. The control unit of the processor has been designed to interpret an external power management signal. Based on the power and performance requirements, this signal specifies a performance slow down factor. The power block has been added in the processor architecture that inserts no-ops in proportion to the slow down factor in the instruction stream. The normal clock rate is…
