Crosstalk analysis for high-speed pulse propagation in lossy electrical interconnections

The effects of interconnection loss (both DC loss and skin effect loss) on crosstalk noise for a coupled lossy interconnection system, with various termination conditions, coupled lengths, spacings, and interconnection structures (microstrip lines versus strip lines) are investigated. Fourier transform techniques and numerical methods are applied to solve the coupled transmission line equations for the strong coupling case (mutual coupling between the active line and the quiet line). The interconnection is either terminated by its approximated matched load impedance, R/sub o/, or by the equivalent loading capacitance of the receiver, C/sub L/. General design guidelines for controlling the crosstalk noise and reflection noise in lossy interconnections are discussed. >
An Evaluation of Three Representative Multimedia Models Used to Support Cleanup Decision‐Making at Hazardous, Mixed, and Radioactive Waste Sites

The decision process involved in cleaning sites contaminated with hazardous, mixed, and radioactive materials is supported often by results obtained from computer models. These results provide limits within which a decision-maker can judge the importance of individual transport and fate processes, and the likely outcome of alternative cleanup strategies. The transport of hazardous materials may occur predominately through one particular pathway but, more often, actual or potential transport must be evaluated across several pathways and media. Multimedia models are designed to simulate the transport of contaminants from a source to a receptor through more than one environmental pathway. Three such multimedia models are reviewed here: MEPAS, MMSOILS, and PRESTO-EPA-CPG. The reviews are based on documentation provided with the software, on published reviews, on personal interviews with the model developers, and on model summaries extracted from computer databases and expert systems. The three models are reviewed within the context of specific media components: air, surface water, ground water, and food chain. Additional sections evaluate the way that these three models calculate human exposure and dose and how they report uncertainty. Special emphasis is placed on how each model handles radionuclide transport within specific media. For the purpose of simulating the transport,more » fate and effects of radioactive contaminants through more than one pathway, both MEPAS and PRESTO-EPA-CPG are adequate for screening studies; MMSOILS only handles nonradioactive substances and must be modified before it can be used in these same applications. Of the three models, MEPAS is the most versatile, especially if the user needs to model the transport, fate, and effects of hazardous and radioactive contaminants. 44 refs., 2 tabs. « less

Aim: To see if there was a link between menstruation issues and psychological stress among young medical students. Methods: A non-probability convenient sampling method was used to conduct an observational (cross-sectional) study on a sample of 180 university-bound students. Students were assessed for menstrual regularity associating with psychological stress by using Perceived Stress Scale in different universities of Lahore. Results: The study included approximately 92% of females with a regular menstrual cycle and 8% of females with an irregular menstrual cycle.While among irregular menstrual cycles, 5 had high levels of stress, 7 had moderate levels of stress, and 3 had mild levels of stress. The normal menstrual cycle group had 40 females with high levels of stress, 121 females with moderate levels of stress, and four females with low levels of stress. Conclusion: Although fewer students suffered from menstruation difficulties, the majority of them, including those who did not, experienced psychological stress. Keywords: Menstrual disorders, dysmenorrheal, abnormal menstrual cycle, stress
Recent Insights and Multifactorial Applications of Carbon Nanotubes

Nanotechnology has undergone significant development in recent years, particularly in the fabrication of sensors with a wide range of applications. The backbone of nanotechnology is nanostructures, which are determined on a nanoscale. Nanoparticles are abundant throughout the universe and are thought to be essential building components in the process of planet creation. Nanotechnology is generally concerned with structures that are between 1 and 100 nm in at least one dimension and involves the production of materials or electronics that are that small. Carbon nanotubes (CNTs) are carbon-based nanomaterials that have the structure of tubes. Carbon nanotubes are often referred to as the kings of nanomaterials. The diameter of carbon is determined in nanometers. They are formed from graphite sheets and are available in a variety of colors. Carbon nanotubes have a number of characteristics, including high flexibility, good thermal conductivity, low density, and chemical stability. Carbon nanotubes have played an important part in nanotechnology, semiconductors, optical and other branches of materials engineering owing to their remarkable features. Several of the applications addressed in this review have already been developed and used to benefit people worldwide. CNTs have been discussed in several domains, including industry, construction, adsorption, sensors, silicon chips, water purifiers, and biomedical uses, to show many treatments such as injecting CNTs into kidney cancers in rats, drug delivery, and directing a near-infrared laser at the cancers. With the orderly development of research in this field, additional therapeutic modalities will be identified, mainly for dispersion and densification techniques and targeted drug delivery systems for managing and curing posterior cortical atrophy. This review discusses the characteristics of carbon nanotubes as well as therapeutic applications such as medical diagnostics and drug delivery.
A Novel Technique for Fingerprint Based Secure User Authentication

Fingerprint biometrics are extremely popular among digital identity systems for authentication. Most fingerprint based authentication systems store unique minutiae points information of a user directly in the database as their template. An adversary can potentially attack the user template that could compromise information of minutiae points. It has been proven that a fingerprint can be reconstructed from minutiae points and hence there is an important requirement in fingerprint based biometric systems to provide protection and privacy. This article introduces a novel technique to provide enhanced protection for fingerprint based biometrics, taking into account the attributes of minutiae point, the ridge count between the neighbouring minutiae points and the local minutiae point structure. The proposed technique has been implemented and tested on a total of nine fingerprint databases of varying quality. In comparison to the other existing techniques under different scenarios, the proposed technique exhibits superior recognition performance. The proposed technique is a singular point independent and has shown high stability, robustness, and security.
Rate of Postoperative Urinary Retention after Anterior Compartment Prolapse Surgery: A Randomized Controlled Trial Comparing Early versus Conventional Transurethral Catheter Removal

Background: Pelvic organ prolapse is a common condition of pelvic floor dysfunction in women, especially in adult vaginally parous and elderly women. Because of its anatomy, the anterior compartment has a significant effect on urinary symptoms. Anterior colporrhaphy and colpocleisis are major anterior compartment prolapse-related surgeries. As we know, postoperative urinary retention (POUR) is one of the most common complications following pelvic floor surgery. To prevent this complication, indwelling bladder catheterization is routinely applied. In contrast, to minimize risk of infection and the patient’s discomfort, the catheter should be removed as soon as possible. However, there is a lack of clarity regarding the optimal timing for catheter removal. Therefore, the aim of this trial is to compare the rate of POUR after anterior prolapse surgery between early transurethral catheter removal (24 h postoperatively) and our standard practice (on postoperative day 3). Methods: We conducted a randomized controlled trial among patients undergoing anterior compartment prolapse surgery between 2020 and 2021 at a university hospital. Women were randomized into two groups. After removal, if the second void residual urine volume exceeded 150 mL, POUR was diagnosed, and intermittent catheterization was performed. The primary outcome was the POUR rate. The secondary outcomes included urinary tract infection, asymptomatic bacteriuria, time to ambulation, time to spontaneous voiding, length of hospitalization, and patient satisfaction. Analysis was performed according to the intention to treat principle. The calculated sample size was 68 patients (34 patients in each group) for a 95% confidence interval, 80% power, 5% probability of type I error, and 10% data loss. Discussion: This study demonstrated that early catheter removal was comparable in POUR rate to conventional treatment with shorter hospitalization among patients undergoing anterior compartment prolapse surgery. Additionally, we observed no re-hospitalization owing to POUR. Therefore, early transurethral catheter removal is preferable following anterior compartment prolapse-related surgery.
Verification of cracked section shrinkage curvature models

An attempt is made to theoretically and experimentally verify the shrinkage curvature models presented in Eurocode 2 and BS 8110. These codes claim that the models originally derived and proven for uncracked sections are suitable, with modification, for predicting the behaviour of cracked sections, although this claim has never been proven experimentally. To achieve verification, an alternative theoretical approach is initially proposed in this paper. In this theoretical model, the effect of shrinkage, creep and the variation in the neutral axis position of the section are taken into account. The stresses developed in the steel and concrete at a cracked section according to this theoretical model are then applied to a finite-element (FE) model representing a portion of the beam from the crack to mid-way between the crack and an adjacent crack. Ultimately, the mean curvature is determined. Experimentally, pairs of beams were cast and subjected to a level of flexural loading to produce a stabilised crack pa.
Missing data completion method based on KNN and random forest

Data missing is one of the relatively difficult problems in the process of data mining,because the lack of part of the property value will seriously affect the results of data analysis. Most of the absence of missing value interpolation does not take into account the relationship between missing properties and other attributes in the sample. Aiming at this problem, this paper proposes a missing data based on KNN and random forest completion algorithm (RF-KNN) . Algorithm firstly chosen by KNN model of K value, makes it as building one of the parameters of the random forest. Then according to the characteristics of the random forest attribute, attribute classification prediction model was constructed, the missing attribute value for effective completion. Through model test and evaluation on the public data sets, the results show that compared with the traditional KNN algorithm and random forest, RF-KNN in more than one, this method is applicable to a variety of data missing value in the field of completion,which can effectively improve the efficiency of data mining analysis.
Validation of Cluster Bomb Mathematical Model

*† ‡ This work consists of the concepts and some results of solutions for aircraft – external store configuration aerodynamic interference. The main emphasis is placed on practical, cost-effective engineering solution of the complex problem with reasonable computational efficiency allowing the code to run on PC computers. Prediction of external stores separation trajectories is an important task in the aerodynamic design area having the objective to define the operational, release envelopes. To attain this purpose, a technique based on the Non-linear Panel Method with unsteady free wake formulation has been developed. The comparison with the flight test as well as wind tunnel investigations has proved the reliability of this methodology.
Lymphoma recognition based on CNN models

Being part of hematopoietic lymphoid tissue tumors, lymphoma has aroused wide concerns in the field of cancer research. Therefore, a lymphatic cancer diagnosis has become a popular question in medical image processing, with numerous works are proposed. Recent works focus on how to get the appropriate image for a better cancer diagnosis. However, the question of how to get a higher accuracy just by learning from the dataset of the images of lymphatic node sections has not been paid attention to. This paper aims to solve this problem by applying a convolutional neural network (CNN), which has nine convolution layers, four dropout layers, three maxpooling layers, two dense layers, and one flatten layer in total. Experiments on the PatchCamelyon dataset show that our method can handle the Lymphoma cancer diagnosis problem with an accuracy of 93.15%, much higher than that of the LeNet and AlexNet, which are 83.17% and 84.49%, respectively. With such high accuracy, our model has the potential of acting as a reliable assistant for doctors when diagnosing lymphoma cancers.
Multi-armed bandit algorithms over DASH for multihomed client

—There is an expanding request from the mobile clients of video trafﬁc which has come to over the most recent two years the greater part of all the mobile data trafﬁc. The challenge of providing the clients excellent video streaming is expected principally to the constrained transfer speed which makes it important to misuse the rising decent variety of mobile video spilling and get to systems. For enhancing the video quality received by ”multi-homed client” (i.e., clients with multiple network interfaces), a network selection algorithm based on the Multi-Armed Bandit heuristic is proposed on top of the most broadly utilized standard for video streaming Dynamic Adaptive Streaming over HTTP (DASH). For choosing the best network at each progression powerfully, DASH gives mobile video quality dependent on the apparent exhibition from the pre-owned system association through the Adaptive Bitrate Rules (ABR) without investigating the system conditions through the other network(s) which could give better quality. Subsequently, a few alterations for DASH ABR is required to enhance the video quality. Two of the MAB algorithms (UCB and Epsilon Greedy) were embraced for improving MPEG-Dash. The investigations are performed through a proving ground execution to show that UCB surpasses Epsilon Greedy, in stable system conditions, regarding goodput received by the Dash customer. Additionally, UCB can discover the harmony between investigating new choices, and abusing the triumphant variation.
Antenna study and design for ultra wideband communication applications

Since the release by the Federal Communications Commission (FCC) of a bandwidth of 7.5GHz (from 3.1GHz to 10.6GHz) for ultra wideband (UWB) wireless communications, UWB is rapidly advancing as a high data rate wireless communication technology. As is the case in conventional wireless communication systems, an antenna also plays a very crucial role in UWB systems. However, there are more challenges in designing a UWB antenna than a narrow band one. A suitable UWB antenna should be capable of operating over an ultra wide bandwidth as allocated by the FCC. At the same time, satisfactory radiation properties over the entire frequency range are also necessary. Another primary requirement of the UWB antenna is a good time domain performance, i.e. a good impulse response with minimal distortion. This thesis focuses on UWB antenna design and analysis. Studies have been undertaken covering the areas of UWB fundamentals and antenna theory. Extensive investigations were also carried out on two different types of UWB antennas. The first type of antenna studied in this thesis is circular disc monopole antenna. The vertical disc monopole originates from conventional straight wire monopole by replacing the wire element with a disc plate to enhance the operating bandwidth substantially. Based on the understanding of vertical disc monopole, two more compact versions featuring low-profile and compatibility to printed circuit board are proposed and studied. Both of them are printed circular disc monopoles, one fed by a micro-strip line, while the other fed by a co-planar waveguide (CPW). The second type of UWB antenna is elliptical/circular slot antenna, which can also be fed by either micro-strip line or CPW. The performances and characteristics of UWB disc monopole and elliptical/circular slot i antenna are investigated in both frequency domain and time domain. The design parameters for achieving optimal operation of the antennas are also analyzed extensively in order to understand the antenna operations. It has been demonstrated numerically and experimentally that both types of antennas are suitable for UWB applications.
Emerging Topics in Cancer Evolution

Cancer results from an evolutionary process where somatic mutations accumulate in distinct populations of cells.1 This theory has been corroborated by high-throughput sequencing studies of tumors in the last decade,2 demonstrating that a tumor is not homogeneous but rather composed of clones with varying sets of somatic mutations. This phenomenon of intra-tumor heterogeneity is a major cause of relapse and resistance to treatment.3 Metastasis, i.e. the migration of tumor cells to anatomical locations distinct from the primary tumor, is the primary cause of death in cancer.4 Thus, the life history of a tumor is the end product of an evolutionary process characterized by cell division, cell mutation and cell migration. The emerging field of cancer phylogenetics views cancer through the lens of evolution and employs phylogenetic techniques to reconstruct, analyze and compare life histories of tumors.5 This perspective will discuss recent advances in (i) computational methods for reconstructing cancer phylogenies from sequencing data, (ii) the identification of common evolutionary patterns and trajecto-
Sexual Dysfunction and Atopic Dermatitis: A Systematic Review

Atopic dermatitis (AD) is a chronic inflammatory disease of the skin whose main symptom is pruritus and may affect all age ranges. Regarding the prevalence, it has been estimated at around 10% of the world population. Many concomitant diseases have been associated with AD, but the causal relationship between AD and psychological impairment has not been clearly established. Scientific literature studying the probable association between male or female sexual dysfunction and dermatological pathology is limited, even more so in AD. This systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines and the Cochrane Collaboration methodology for systematic reviews. All relevant articles in English were identified through a search from inception to 10 December 2020, including the following databases: Medline (via PubMed), Scopus, Web of Science Core Collection, and SciELO. The results of the search were compiled using the COVIDENCE software for systematic reviews. The methodological quality of the included studies was done using the “Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies” and the “Quality Assessment of Case-Control Studies” developed by the National Heart, Lung, and Blood Institute, National Institutes of Health (NIH). Our search yielded potentially relevant studies. Five studies that evaluated the prevalence of sexual dysfunction in atopic dermatitis were retrieved after applying the selection criteria. The present systematic review achieved data from 8088 patients with atopic dermatitis from four articles. Sample sizes for atopic dermatitis patients ranged from 266 to 3997. We identified one cohort study with four years of follow-up, three studies with a cross-sectional design, and one case-control study. Three studies reported data disaggregated by the severity of atopic dermatitis. Two studies included healthy controls with a total sample size of 1,747,755 subjects. Two studies compared data with other dermatological conditions such as psoriasis. In conclusion, we can establish that unlike other psychological comorbidities such as anxiety and depression, sexual dysfunction is a field scarcely explored in the literature. This sexual dysfunction focuses on the male sex in large population studies and in clinical diagnoses without exploring it through specific and validated questionnaires in this regard. Further studies focused on both genders are needed. It is important to correlate this sexual dysfunction with the severity of the disease, previous treatments, and cardiovascular comorbidities.
Effectiveness of Global Optimisation and Direct Kinematics in Predicting Surgical Outcome in Children with Cerebral Palsy

Multibody optimisation approaches have not seen much use in routine clinical applications despite evidence of improvements in modelling through a reduction in soft tissue artifacts compared to the standard gait analysis technique of direct kinematics. To inform clinical use, this study investigated the consistency with which both approaches predicted post-surgical outcomes, using changes in Gait Profile Score (GPS) when compared to a clinical assessment of outcome that did not include the 3D gait data. Retrospective three-dimensional motion capture data were utilised from 34 typically developing children and 26 children with cerebral palsy who underwent femoral derotation osteotomies as part of Single Event Multi-Level Surgeries. Results indicated that while, as expected, the GPS estimated from the two methods were numerically different, they were strongly correlated (Spearman’s ρ = 0.93), and no significant differences were observed between their estimations of change in GPS after surgery. The two scores equivalently classified a worsening or improvement in the gait quality in 93% of the cases. When compared with the clinical classification of responders versus non-responders to the intervention, an equivalent performance was found for the two approaches, with 27/41 and 28/41 cases in agreement with the clinical judgement for multibody optimisation and direct kinematics, respectively. With this equivalent performance to the direct kinematics approach and the benefit of being less sensitive to skin artefact and allowing additional analysis such as estimation of musculotendon lengths and joint contact forces, multibody optimisation has the potential to improve the clinical decision-making process in children with cerebral palsy.
Attosecond pulse generation using the multistage nonlinear microring resonators

We propose a new system of an attosecond pulse generation by using the integrated nonlinear microring devices. A soliton light pulse with wavelength of 1550 nm is entered into the multistage microring resonators, where the ring radii of the recent integrated device product are within the range from 5 to 10 microns. Results obtained have shown that the ultrashort pulse width in the attoscale regime and beyond can be easily generated. When the input peak power of 12 W is applied into the system, the generated pulse with pulse width of 50 is achieved. © 2008 Wiley Periodicals, Inc.
