Doppler ultrasonography screening of poor-grade subarachnoid hemorrhage patients increases the diagnosis of deep venous thrombosis

Abstract Background: Prophylactic anticoagulation greatly decreases the prevalence of deep venous thrombosis (DVT) in neurosurgical patients. Using Doppler ultrasonography (USG), recent studies demonstrate a 1% DVT detection rate following microsurgery or endovascular treatment for aneurysmal subarachnoid hemorrhage (aSAH). We hypothesize that reported statistics underestimate the DVT detection rate in this high risk cohort by accounting for only symptomatic thromboses. This study utilizes Doppler USG to examine the prevalence of DVT in a large population of aSAH patients and attempts to identify a high-risk subgroup within this cohort. Methods: We retrospectively examined 178 aSAH patients who underwent screening lower extremity Dopplers (LEDs) and 57 who did not undergo screening LEDs. All received pharmacologic and mechanical DVT prophylaxis. We analysed DVT prevalence within these two groups and compared rates to the literature. We then segregated patients according to Hunt–Hess grade and determined DVT prevalence within subgroups. Results: Patients who underwent LED screening demonstrated a 3.4% (6/178) DVT rate, compared to 0% (0/57) in the unscreened cohort. Our screening protocol yielded a thrombosis rate almost triple that reported in the literature (3.4% versus 1.2%). A significantly greater (p<0.05) percentage of screened Hunt–Hess III–V patients (6.5%, 6/93) had positive LEDs compared to Hunt–Hess I–II patients (0%, 0/85). Conclusion: These data suggest that while pharmacologic prophylaxis lowers the prevalence of symptomatic DVTs in aSAH patients, the number of asymptomatic DVTs remains significant, particularly in patients with formidable neurological deficits. While a formal cost-effective analysis is warranted, our data suggest that screening high-risk patients may increase the diagnosis of asymptomatic DVTs and potentially prevent serious medical complications.

Therefore, the application could provide vital information to aid in patient breathing exercises and lung health.
Financial Structure and Bank Profitability

Countries differ in the extent to which their financial systems are bank-based or market-based. The financial systems of Germany and Japan, for example, are considered bank-based because banks play a leading role in mobilizing savings, allocating capital, overseeing investment decisions of corporate managers, and providing risk management vehicles. The systems of the United States, and the United Kingdom are considered more market-based. Using bank-level data for a large number of industrial and developing countries, the authors present evidence about the impact of financial development, and structure on bank performance. They measure the relative importance of bank or market finance by the relative size of stock aggregates, by relative trading or transaction volumes, and by indicators of relative efficiency. They show that in developing countries, both banks and stock markets are less developed, but financial systems tend to be more bank-based. The richer the country, the more active are all financial intermediaries. The greater the development of a country's banks, the tougher is the competition, the greater is the efficiency, and the lower are the bank margins, and profits. The more under-developed the stock market, the greater are the bank profits. But financial structure per se does not have a significant, independent influence on bank margins, and profits.

Urban Memory: Remembering Communities in Urban Redevelopment

How to preserve urban memory under rapid redevelopment is an unresolved issue around the world, especially in China. Going beyond traditional concepts and practices of historic preservation, this paper proposes a solution to local communities through technological intervention. By combining offline storytelling with online collaboration, the Urban Memory project aims to remember communities that would be otherwise forgotten during urbanization.
Strategy Choices of Firms and Market Structure.

This paper suggests a new approach to the empirical analysis of market structure. Market concentration is an aspect of distribution of market shares of firms, and market shares are best modelled at the firm level, bringing into play strategy choices made by firms. It follows that a useful approach to explaining concentration would be a two stage one: to estimate firm size or market shares as a function of firm level determinants, and to use the information in these estimates to assess the relative contributions of firm characteristics to concentration. The method is illustrated by application to selected Polish manufacturing industries in the early transition period.
Internet Addiction on Campus: The Vulnerability of College Students

Use of the Internet on college campuses has increased dramatically in recent years, leading to pathological use, or Internet addiction, for some students. Internet addiction is defined as a psychological dependence on the Internet and is characterized by (a) an increasing investment of resources on Internet-related activities, (b) unpleasant feelings (e.g., anxiety, depression, emptiness) when offline, (c) an increasing tolerance to the effects of being online, and (d) denial of the problematic behaviors. Individuals exhibiting such symptoms often are dealing with underlying psychological issues. College students are particularly vulnerable to pathological Internet use due to several factors. These factors include (a) the psychological and developmental characteristics of late adolescence/young adulthood, (b) ready access to the Internet, and (c) an expectation of computer/Internet use. The nature of the computer medium and the sense of control experienced when engaged in computer activities can also cont.
Etiology of Chronic Fatigue Syndrome: Testing Popular Hypotheses Using a National Birth Cohort Study

Objective: To review the etiology of chronic fatigue syndrome (CFS) and test hypotheses relating to immune system dysfunction, physical deconditioning, exercise avoidance, and childhood illness experiences, using a large prospective birth cohort. Methods: A total of 4779 participants from the Medical Research Council’s National Survey of Health and Development were prospectively followed for the first 53 years of their life with >20 separate data collections. Information was collected on childhood and parental health, atopic illness, levels of physical activity, fatigue, and participant’s weight and height at multiple time points. CFS was identified through self-report during a semistructured interview at age 53 years with additional case notes review. Results: Of 2983 participants assessed at age 53 years, 34 (1.1%, 95% Confidence Interval 0.8–1.5) reported a diagnosis of CFS. Those who reported CFS were no more likely to have suffered from childhood illness or atopy. Increased levels of exercise throughout childhood and early adult life and a lower body mass index were associated with an increased risk of later CFS. Participants who later reported CFS continued to exercise more frequently even after they began to experience early symptoms of fatigue. Conclusions: Individuals who exercise frequently are more likely to report a diagnosis of CFS in later life. This may be due to the direct effects of this behavior or associated personality factors. Continuing to be active despite increasing fatigue may be a crucial step in the development of CFS. CFS = chronic fatigue syndrome; BMI = body mass index.
SparseNN: An energy-efficient neural network accelerator exploiting input and output sparsity

Contemporary Deep Neural Network (DNN) contains millions of synaptic connections with tens to hundreds of layers. The large computational complexity poses a challenge to the hardware design. In this work, we leverage the intrinsic activation sparsity of DNN to substantially reduce the execution cycles and the energy consumption. An end-to-end training algorithm is proposed to develop a lightweight (less than 5% overhead) run-time predictor for the output activation sparsity on the fly. Furthermore, an energy-efficient hardware architecture, SparseNN, is proposed to exploit both the input and output sparsity. SparseNN is a scalable architecture with distributed memories and processing elements connected through a dedicated on-chip network. Compared with the state-of-the-art accelerators which only exploit the input sparsity, SparseNN can achieve a 10%–70% improvement in throughput and a power reduction of around 50%.
Dynamic Characteristics of Amorphous Photovoltaic Module by Light-induced Degradation

This paper is a study on the impacts of dynamic characteristics on the light-induced degradation phenomena, the modules under test were amorphous tandem (a-Si:H/a-Si:H). There dynamic characteristics of amorphous thin film silicon Photovoltaic module (PV module) by dynamic impedance technique. The I-V characteristics of Photovoltaic (PV) modules are generally measured at Standard Test Condition (STC) or in the dark. It's unable to explain the phenomena in the light-induced degradation in terms of material properties. Dynamic characteristics cannot be revealed by I-V curves measurements. Dynamic impedance were measured and analyzed by using the basic instrument. From the experimental results, it is found that dangling bonds and localized states phenomena resulting from light-induced degradation can obviously be reflected on dynamic parameter with forward biasing. In this paper show the PV module is stable stage about 148 kWh/m or a month, The series resistance (RS) is increased, shunt resistance (Rsh) and internal diode dynamic resistance (Rd(V)) are decreased continuously, Similarly, the diffusion capacitance (CD(V,ω)) were slightly decreased after light-induced by outdoor exposure. The decays observed can be proposed that there states localized of band tails are due to minority carrier lifetime an outside the transition region. It is proportional to the current of electricity, It is according to the Maximum current (Im) and Maximum power (Pm) is decreasing by light-induced degradation.

Structure and function of aquaporin water channels.

The aquaporins (AQPs) are a family of small membrane-spanning proteins (monomer size approximately 30 kDa) that are expressed at plasma membranes in many cells types involved in fluid transport. This review is focused on the molecular structure and function of mammalian aquaporins. Basic features of aquaporin structure have been defined using mutagenesis, epitope tagging, and spectroscopic and freeze-fracture electron microscopy methods. Aquaporins appear to assemble in membranes as homotetramers in which each monomer, consisting of six membrane-spanning alpha-helical domains with cytoplasmically oriented amino and carboxy termini, contains a distinct water pore. Medium-resolution structural analysis by electron cryocrystallography indicated that the six tilted helical segments form a barrel surrounding a central pore-like region that contains additional protein density. Several of the mammalian aquaporins (e.g., AQP1, AQP2, AQP4, and AQP5) appear to be highly selective for the passage of water, whereas others (recently termed aquaglyceroporins) also transport glycerol (e.g., AQP3 and AQP8) and even larger solutes (AQP9). Evidence for possible movement of ions and carbon dioxide through the aquaporins is reviewed here, as well as evidence for direct regulation of aquaporin function by posttranslational modification such as phosphorylation. Important unresolved issues include definition of the molecular pathway through which water and solutes move, the nature of monomer-monomer interactions, and the physiological significance of aquaporin-mediated solute movement. Recent results from knockout mice implicating multiple physiological roles of aquaporins suggest that the aquaporins may be suitable targets for drug discovery by structure-based and/or high-throughput screening strategies.
The Use of Technical Simulation Training in Surgical Education in the United Kingdom

Simulation training, where a scenario or setting is replicated, is now firmly associated with surgical training. Involving both technical and non-technical competencies, it provides a valuable tool in training new skills to both new and current surgeons. As patient safety becomes more of a focus, alongside advances in technology and surgical techniques, there is a continued concern regarding operative exposure for futures surgeons. This void in which simulated training fits, a claim supported by an expanding literature base. The recent integration of simulation into training curricula aims to promote consistency in access to simulation facilities across deaneries and invite the experience of dedicated instructors to optimise educational use.
Instability of Variable Thermal Conductivity Magnetohydrodynamic Nanofluid Flow in a Vertical Porous Channel of Varying Width

A numerical investigation is performed into the heat transfer and entropy generation of a variable thermal conductivity magnetohydrodynamic flow of Al2O3-water nanofluid in a vertical channel of varying width with right porous wall, which enable the fluid to enter. The effects of the Lorentz force, buoyancy force, viscous dissipation and Joule heating are considered and modeled using the transverse momentum and energy balance equations respectively. The governing nonlinear partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations using appropriate similarity transformations and then solved numerically using power series with Hermite-Padé approximation method. A stability analysis has been performed for the local rate of shear stress and Nusselt number that indicates the existence of dual solution branches. Numerical results are achieved for the fluid velocity, temperature as well as the rate of heat transfer at the wall and the entropy generation of the system. The present results are original and new for the flow and heat transfer past a channel of varying width in a nanofluid which shows that the physical parameters have significant effects on the flow field.
Current Trends in Vehicular Ad Hoc Networks

Vehicular Networks are receiving a lot of attention due to the wide variety of services they can provide. Their applications range from safety and crash avoidance to Internet access and multimedia. A lot of work and research around the globe is being conducted to define the standards for vehicular Communications. These include frequency allocation, standards for physical and link layers, routing algorithms, as well as security issues and new applications. In this paper we review the standardization work and researches related to vehicular networks and discuss the challenges facing future vehicular networks. millions of people around the world die every year in car accidents and many more are injured. Implementations of safety information such as speed limits and road conditions are used in many parts of the world but still more work is required. Vehicular Ad Hoc Networks (VANET) should upon implementation, collect and distribute safety information to massively reduce the number of accidents by warning drivers about the danger before they actually face it. Such networks comprise of sensors and On Board Units (OBU) installed in the car as well as Road Side Units (RSU). The data collected from the sensors on the vehicles can be displayed to the driver, sent to the RSU or even broadcasted to other vehicles depending on its nature and importance. The RSU distributes this data, along with data from road sensors, weather centers, traffic control centers, etc to the vehicles.
Bleeding and thrombosis in acute promyelocytic leukemia

Acute promyelocytic leukemia (APL) has evolved from being a deadly to a highly curable disease, due totargeted molecular therapy with all‐trans retinoic acid (ATRA). As a result, the incidence of early hemorrhagic deaths for which APL is notorious has reduced to 5–10% as reported in clinical trials. These results are not replicated outside of clinical trials as is evident from recent population‐based registries. High incidence of early hemorrhagic deaths remains the greatest contributor to treatment failure in this otherwise curable leukemia. Additionally, thrombosis is now being increasingly recognized in APL patients and may be associated with ATRA usage. Am. J. Hematol. 87:596–603, 2012. © 2012 Wiley Periodicals, Inc.
Implementation of stereo vision algorithm on signal processing hardware for depth estimation

Depth estimation has vital importance in various applications like Advance driver assistance systems, Robot navigation, 3D movies, etc. Depth information is represented using disparity maps which are generated from various stereo correspondence algorithms. This paper proposes an implementation of Semi global block matching algorithm on raspberry pi using python. The proposed algorithm generates a disparity map by block wise matching and smoothness constraint. The novel algorithm is compared with other algorithms on the standard dataset. It provides an efficient accuracy over local methods. The real time implementation of SGM algorithm on the system uses a block size of 21 × 21 for images having resolution 1280×720P. The system provides faster processing time for the proposed algorithm.
Pruning representations in a distributed model of working memory: a mechanism for refreshing and removal?

Substantial behavioral evidence suggests that attention plays an important role in working memory. Frequently, attention is characterized as enhancing representations by increasing their strength or activation level. Despite the intuitive appeal of this idea, using attention to strengthen representations in computational models can lead to unexpected outcomes. Representational strengthening frequently leads to worse, rather than better, performance, contradicting behavioral results. Here, we propose an alternative to a pure strengthening account, in which attention is used to selectively strengthen useful and weaken less useful components of distributed memory representations, thereby pruning the representations. We use a simple sampling algorithm to implement this pruning mechanism in a computational model of working memory. Our simulations show that pruning representations in this manner leads to improvements in performance compared with a lossless (i.e., decay‐free) baseline condition, for both discrete recall (e.g., of a list of words) and continuous reproduction (e.g., of an array of colors). Pruning also offers a potential explanation of why a retro‐cue drawing attention to one memory item during the retention interval improves performance. These results indicate that a pruning mechanism could provide a viable alternative to pure strengthening accounts of attention to representations in working memory.
Harmonic-Spectrum Spreading Effects of Two-Phase Random Centered Distribution PWM (DZRCD) Scheme With Dual Zero Vectors

In this paper, a two-phase dual-zero-vector random centered distribution (DZRCD) scheme is proposed to solve the problems of a two-phase RCD pulsewidth modulation with V(000) as the zero vector in which the discrete spectra in the case of a high modulation index (M) are not considerably reduced. In the proposed DZRCD scheme, the zero vector is selected as V(111) when M ges 0.8 and as V(000) when M < 0.8. A 16-b microcontroller SAB-C167 was used for the implementation of the proposed method. The experiments were performed on a 1.5-kW induction motor under a 2-A load condition, and for a load test, an induction motor was used as an eddy current brake. Simulation and experimental results show that the voltage and current harmonics are spread over a wideband area and that the audible switching noise is reduced by the proposed method.
