Not “doing the same thing over and over again”

Intracerebral hemorrhage (ICH) with intraventricular extension is a devastating disease occurring in 40% of patients with spontaneous ICH. Although the CLEAR III trial (NCT00784134) demonstrated mortality reduction with intraventricular alteplase (versus saline), lessons learned warrant a therapeutic trial focusing on disease severity and treatment endpoints that support a high likelihood of improvement. We must answer questions of maximizing therapy intensity in large intraventricular hemorrhage (IVH) to promote good neurologic outcomes if we are committed to treating ICH and the full spectrum of stroke severity.
Hyperspectral image classification based on multi-scale information compensation

ABSTRACT By virtue of their effective capabilities of deep feature extraction, deep learning methods, especially convolutional neural network (CNN) algorithms have exhibited significant potential for hyperspectral image (HSI) classification. However, in information propagation, the amount of semantic information constantly increases while detailed information that representing small-scale local features of object vanishes. In addition, the scale singularity of the extracted feature restricts improvement in the accuracy of classification. In this letter, a multiscale CNN-based module called information compensation is proposed that can maintain detailed information while preserving semantic information by integrating the original input with more abstract hierarchical learning feature maps. An end-to-end network based on this module that takes advantage of spatial information is proposed for HSI classification. Furthermore, in the foundation of this network, spectral information is considered to develop a spatial–spectral hybrid framework. Experimental results on two-public HSI datasets show that the proposed networks achieve competitive performance compared with other state-of-the-art CNN-based methods.
KNOWLEDGE OF ALZHEIMER’S DISEASE AND TRAINING NEEDS IN FINAL YEAR MEDICAL AND PHARMACY STUDENTS

Although a significant number of medical and pharmacy professionals come into contact with an increasing number of individuals with Alzheimer’s disease and other dementias, there is concern on the lack of knowledge and skills received during their undergraduate training programmes with the consequence of not providing the required hospital and community care for these individuals following programme completion. The aim of this report is to describe the results of a small scale study investigating the level of knowledge of Alzheimer’s disease and training needs in medical and pharmacy students at the end of their final year of undergraduate training. The findings indicated a lack of in-depth knowledge for both categories of students, in particular on risk factors and pharmacotherapeutic management highlighting an urgent need of refining existent training programmes that equip future medical and pharmacy professionals with the necessary skills in providing adequate care and management for individuals with the disease.
Profile of, and challenges experienced by, stroke patients admitted at Haydom Lutheran hospital, Tanzania

Background and aim: Despite the high number of strokes globally, and among people of African origin in particular, there are few available data on stroke in most countries of sub-Saharan African (SSA), including Tanzania. In addition, the profile and challenges affecting stroke patients in these countries has not been adequately explored. The aim of this study was to determine the profile and explore the challenges experienced by stroke patients admitted at Haydom Lutheran Hospital in Tanzania. The objectives of the study were to determine the documented risk factors among the patients admitted to Haydom Lutheran Hospital, to identify the stroke on-set admission interval and length of hospital stay, to identify the process of physiotherapy for the stroke patients, and to explore the challenges experienced by stroke patients discharged from Haydom Lutheran Hospital, Tanzania. Methods: Qualitative and quantitative research designs were used to collect the data. The quantitative design used a retrospective descriptive study, in which medical records of stroke patients were reviewed. The qualitative approach included in-depth interviews to collect information regarding the challenges experienced by stroke patients residing in Haydom, Tanzania. Existing medical records were perused to obtain information related to demographic profile, medical characteristics and rehabilitation data among stroke patients admitted at Haydom Lutheran Hospital. Relevant data was captured on a data information sheet. The SPSS (14.0 version) and Microsoft Excel (2007) were used to analyse quantitative data. Descriptive Statistics were used to determine ranges, percentages, frequencies, means and standard deviations calculate. The qualitative interviews were transcribed verbatim and also translated from Kiswahili to English. Stated concepts were coded, grouped into categories, and reduced into sub-themes and main themes. Prior to conducting this study, final permission was obtained from the Senate Research Grant and Study Leave Committee at the University of the Western Cape as well as the relevant authorities of the Tanzania Ministry of Health, Tanzanian National Institute of Medical Research, and the Administration of Haydom Lutheran Hospital. Written informed consent were obtained from the participants prior to interviews.

Multimodal Assessment of Structure and Function in Inherited Retinal Degenerations

Author(s): Foote, Katharina | Advisor(s): Roorda, Austin | Abstract: Inherited retinal degenerations (IRDs) affect approximately 1:4,000 people worldwide and are currently the leading cause of vision loss of people between the ages of 15-45. The mechanisms of degeneration in many IRDs remain unclear. It is vital to establish relationships between retinal structural and functional measures in order to better understand the relationship between the genetic mutations and the phenotypes they cause in these diseases. For example, retinitis pigmentosa (RP), the most prevalent IRD, and choroideremia (CHM), an X-linked degeneration that affects choroidal, RPE and photoreceptor cells, both progress over time due to rod, then cone, photoreceptor loss. Greater understanding of disease progression may clarify the underlying mechanisms of retinal degenerations. Furthermore, the development of novel outcome measures could accelerate clinical trials of treatments designed to treat these relentless, sight-threatening diseases. The experiments and research described in this document use multimodal state-of-the-art, novel, high-resolution techniques in addition to standard technologies used in the clinical setting to study the relationship between structure and function of the retina including rod and cone photoreceptors, retinal pigment epithelium, choriocapillaris and other retinal layers affected in the eyes of patients with retinal degeneration.

Fractal Asset Pricing Models for Financial Risk Management

The article presents the analysis findings of the problems and prospects of using the fractal markets theory to mathematically predict the price dynamics of assets as part of a financial risk management strategy. The aim of the article is to find out the features of value of bank assets and to develop recommendations for assessing financial risks based on mathematical methods for forecasting economic processes. Theoretical and empirical research methods were used to achieve the aim. The article reveals the features of mathematical modeling of economic processes related to asset pricing in a volatile market. It was proved that using financial mathematics in banking contributes to the stable development of the economy. Mathematical modeling of the price dynamics of financial assets is based on a substantive hypothesis and supported by an adequate apparatus of fractal pair pricing models in order to reveal specific market relations of business entities. According to the authors, the prospects of using forecast models to minimize the financial risks of derivative financial instruments are positive. The authors concluded that the considered methods contribute to managing financial risks and improving forecasts, including operations with derivatives. Besides, the studied fractal volatility parameters proved the predictive power regarding extreme events in financial markets, such as the bankruptcy of Lehman Brothers investment bank in 2008. The relevance of the article is due to the fact that the favorable investment climate and the use of modern financing methods largely depend on the effective financial risk management.
Diversity of arbuscular mycorrhizal fungi communities associated with cape gooseberry (Physalis peruviana L.) crops

The diversity of arbuscular mycorrhizal fungi (AMF) communities in agricultural systems depends on biotic and abiotic factors as well as on cultural practices. This research aimed to evaluate the diversity of AMF present in an altitudinal transect cultivated with cape gooseberry (Physalis peruviana L.). A set of 13 soil samples from cape gooseberry plantations located in the Colombian Andean mountains in the provinces of Cundinamarca and Boyaca were collected during dry (0-20 mm/month) and rainy (150-330 mm/month) seasons between 1500 and 3000 m a.s. l. , in order to establish the relationship between the altitudinal characteristics and AMF diversity. The evaluation of the abundance of spores and species and diversity indexes showed the presence of 46 AMF species in the dry season and 31 in the rainy season. This shows the high diversity of AMF in the tropical Andes with spore abundance between 20 and 120 spores 10 g-1 of soil in the rainy season and between 127 and 1531 spores 10 g-1 of soil in the dry season.
Multicriteria UAV Base Stations Placement for Disaster Management

In disaster situations, collapse of local communication infrastructure is a major issue due to destruction of buildings, antennas, power sources, and to name a few. Drones, as flying base stations, are a promising solution to restore essential communication services in emergency situations. The contribution of this article is twofold: First, an efficient computer vision technique is proposed to identify areas with high density of low mobility or stationary users. This is done using a multistep process, which includes image acquisition, classification, and crowd density estimation. Next, an accurate mathematical model is presented for joint optimization of drone base stations placement and user assignment. The goal here is to maximize the number of serviced users with minimum number of drones, while satisfying practical network constraints. An optimal solution to such a biobjective optimization problem has complexity exponential to the network size. Furthermore, a low complexity heuristic is proposed to solve the optimization problem. Complexity analysis of the proposed solution is then carried out. Simulation results for a number of practical network scenarios demonstrate that the proposed solution achieves a performance comparable to the optimal solution.
Evaluation of the efficacy of gingival crevicular blood in predicting the glycemic control

Background and Aim: Diabetes has emerged as a major healthcare problem in India. Diabetes and periodontitis interact in a bidirectional manner; therefore, there is a need to screen patients for diabetes in dental clinics. Development of an intraoral blood sampling technique would make screening easier for dental practitioners. Routine oral examination of patients with periodontal inflammation with or without diabetes produce ample bleeding which can be used in glucometers for screening diabetes mellitus. Therefore, the aim is to assess if gingival crevicular blood (GCB) is as efficient as capillary finger prick technique in estimating the glycemic status. Settings and Design: This was a cross-sectional study. Materials and Methods: Fifty-eight participants with gingivitis or periodontitis with bleeding on probing from at least one site were chosen. Periodontal parameters such as Probing pocket depth and gingival index were measured using William's graduated periodontal probe. GCB and capillary finger prick blood (CFB) were collected for the estimation of blood glucose with the help of glucometer. Statistical Analysis: Performed using Pearson's correlation coefficient. Results: The Pearson correlation coefficient of GCB and CFB was 0.982 with a P < 0.001. Conclusion: It can be concluded that GCB can be used for the estimation of glycemic status.
A Compact Single-Layer Four-Port Orthogonally Polarized Yagi-Like MIMO Antenna System

A wideband compact Yagi-like directional multiple-input–multiple-output (MIMO) antenna system is presented based on a slot loop excitation. Four orthogonally polarized beams are generated by orthogonally feeding the slot loop elements using microstrip lines. The proposed design is based on a single-layer geometry with an overall size of $35\times 90\times 0.76$ mm3, which is suitable for compact wireless handheld devices. The conventional vertically polarized omnidirectional beams from each slot loop element are made directional and horizontally polarized by using two passive complementary slot reflector (CSR) elements. The antenna system has a wide measured bandwidth of 620 MHz (3.26–3.88 GHz) targeting the 3.6 GHz WiMAX band. It has a maximum realized gain of 4 dBi and front to back ratio (FBR) of more than 7 dB within the band of operation. The proposed antenna system shows good MIMO performance with a minimum measured isolation of 10 dB between the adjacent ports and more than 20 dB between other ports. The orthogonal beams of the antenna system help in achieving low envelope correlation coefficient (ECC) values of less than 0.1. The measured total efficiency of the antenna system is more than 75% for all the ports of the antenna system.
Majority Party, Standing Committees, and Evidence for Indirect Control1

Abstract The majority party leadership has different goals for different committees. As such, they tailor a variety of control mechanisms to match different committees. When a committee is considered “highly important” to the majority party leadership, the leadership employs an intra-party assignment strategy: assigning members who are ideologically similar to the party caucus (per conventional wisdom). This direct control mechanism consequently produces an unconditionally low level of committee bias. For “medium importance” committees, however, the majority party leadership employs an inter-party assignment strategy to exert indirect control: utilizing the presence of minority party members to constrain their own party delegations in a way that serves the party in general. As such, the bias of these committees inevitably depends on the ideological distribution of the minority party committee delegations. This ultimately suggests that the majority party leadership adopts multiple and flexible strategies to deal with committee assignments and committee activities in general.
A grounded theory of local ownership as meta-conflict in Afghanistan

Internationally sponsored interventions in fragile and conflict-affected states are often resisted by domestic actors who have deep local knowledge, profoundly different expectations of political processes, and keen desires to shape their country’s future. Many forms of local resistance can damage or stall the progress of externally driven peacebuilding, but the critical peacebuilding literature has suffered from an inability to articulate coherent strategic alternatives to the dominant paradigm of liberal interventionism. This paradigm, we argue, is actually part of what fuels continued resistance: as external actors seek to implant liberal democratic norms into local bureaucratic and political cultures, countless sites of conflict emerge, with local and international actors jockeying between and amongst each other for position, resources, and control over the specificities of reform. These struggles – effectively a competition over local ownership – are at the centre of peacebuilding and will determine short- and long-term intervention outcomes. Focusing on the case of political reform in Afghanistan, this article develops a grounded theory of ownership as ‘meta-conflict’, in which participant voices from local and international peacebuilding leaders, working in-country, are given a primary role in determining the compatibility of the donor community’s prevailing liberal agenda with local requirements for building peace.
Double boost‐flyback converter

A high-gain step-up non-isolated dc–dc converter is proposed in this study, named the double boost-flyback converter. The topology combines two conventional boost-flyback converters with input-parallel and floating-output connections. The new topology increases the static gain and reduces the input current ripple in relation to the conventional boost-flyback topology. The proposed converter has the potential to be used in low input voltage applications that require a high gain, such as systems powered by photovoltaic panels, fuel cells, electric vehicles, and low voltage batteries. This study provides details on the principle of operation, static gain, control strategy, design guide and experimental verification. A 1 kW prototype was designed and built for an input voltage of 48 V and an output voltage of 800 V, reaching a static gain of 16.67. The maximum efficiencies obtained were 94.6% at 70% of load and 93.9% at rated load.
Valuing vulnerable options with two underlying assets

ABSTRACT In this paper, we consider vulnerable options with two underlying assets, including options on the maximum of two underlying prices, options paying the best and cash, and options on the maximum of two geometric average prices. We derive the explicit pricing formulae of these options and perform numerical examples to illustrate prices of these options.
The Relationship between Anxiety, Depression, and Quality of Life among Breast Cancer Patients in Seyedoshohada Hospital in Isfahan in 2016: The Mediating Role of Resilience

Background and Objective: While being diagnosed with breast cancer can cause psychological disturbances for patients and decrease their quality of life, resilience can evidently act as a protective factor. The purpose of the current study was to explore the relationship between anxiety, depression, and quality of life among women with breast cancer by considering the mediating role of resilience. Materials and Methods: In the present descriptive study, 92 female patients with breast cancer admitted in Seyedoshohada Hospital, Isfahan, were selected through convenience sampling. The participants filled out cancer patient Quality of life Questionnaire, Hospital Anxiety Depression Scale, and Block & Kremen Ego Resiliency Scale. Descriptive statistics and inferential statistics including Pearson product -moment correlation and hierarchical regression analysis were used in SPSS (version 22) to analyze the data. Results: The mean of anxiety was 10.81±3.46, the mean of depression was 8.56±4.04, the mean of resilience was 45.57±8.89, and the mean of quality of life was 62.95±18.46. The results indicated that there wasa statistically significant relationship between these patients quality of life and their depression (r=-0.74, p less-than .001), anxiety (r=-0.60, p less-than .001), and resilience (r=0.45, p less-than .001). The hierarchical regression analysis results showed that resilience had a mediating role in the relationship between anxiety and depression, in one hand, and the quality of life, in the other hand, among these patients. Conclusion: Anxiety and depression can decrease breast cancer patients quality of life. However, resilience can moderate this effect. Hence, it seems along with medical treatments, appropriate psychological interventions by psychologists, nurses, and social workers for enhancing resilience can have a significant role in improving breast cancer patients quality of life. Key words: Breast cancer, Anxiety, Depression, Quality of life, Resilience, Isfahan Funding: This study did not have any funds. Conflict of interest: None declared.

Research on Five-Level Control Scheme of Hybrid-Bridge Bidirectional DC–DC Converter

Aiming at the problem of excessive short-circuit current in the traditional bridge structure, an improved hybrid-bridge DC–DC converter topology is proposed in this article. The high voltage side of the converter is a hybrid-bridge structure and the low voltage (LV) side is an improved half-bridge double-winding structure which can suppress the rising trend of short-circuit current. Compared with the conventional four-level control for hybrid-bridge structure, a five-level control is proposed to improve the efficiency while the converter works with a wide voltage range. Minimum current stress, smaller reactive power, and wide zero-voltage-switching (ZVS) range can be achieved with the proposed control strategy. In addition, the power can be controlled only using one control variable and its implementation is very simple, only needing a proportional-integral (PI) regulator. Simulation and experimental results verify the above excellent performance of the proposed control.
