Printed Dipole Antenna With Band Rejection Characteristics for UWB Applications
Venue: IEEE Antennas and Wireless Propagation Letters
Year: 2010

This letter presents the design and performance measures of a printed dipole antenna with band rejection characteristics for ultrawideband (UWB) applications. The proposed antenna operates in the frequency range 3.65615.64 GHz with impedance bandwidth of 11.027 GHz and maximum gain of 6.046 dBi. It consists of five dipole strips of different resonant length combined orthogonally for effective signal reception. Inverted L shaped slots were introduced in the ground plane for WLAN band rejection. The band rejection is from 5.066.012 GHz. The radiation pattern is nearly omnidirectional in both the elevation and azimuthal plane due to the orthogonal configuration of the dipole strips. The consistency of the radiation pattern exists within the operating band. The performance of the proposed antenna is confirmed by simulation and experimental method.
Amputation in crush syndrome: A case report
Venue: International journal of surgery case reports
Year: 2020

Highlights Crush syndrome (CS) produces severe electrolyte disorders, circulatory and multiple organ failure due to severe rhabdomyolysis and reperfusion injuries. To date, the main stem of management is aggressive fluid resuscitation. Fasciotomy for the treatment of compartment syndromes due to crush injuries is still controversial, and it is still unknown if early amputation has patient centered benefits. This case suggests a potential benefit of amputation in patients with CS and progressive deterioration. It also invites to think if this is a decision to consider early in the course of the disease. The presence of risk factors for poor prognosis and the natural course of the disease can favor amputation despite the apparent viability of the limb and the morbidity of losing of an extremity.
Effects of Aspirin for Primary Prevention in Persons with Diabetes Mellitus
Venue: The New England journal of medicine
Year: 2018

Diabetes mellitus is associated with an increased risk of cardiovascular events. Aspirin use reduces the risk of occlusive vascular events but increases the risk of bleeding; the balance of benefits and hazards for the prevention of first cardiovascular events in patients with diabetes is unclear.  We randomly assigned adults who had diabetes but no evident cardiovascular disease to receive aspirin at a dose of 100 mg daily or matching placebo. The primary efficacy outcome was the first serious vascular event (i.e. myocardial infarction, stroke or transient ischemic attack, or death from any vascular cause, excluding any confirmed intracranial hemorrhage) The primary safety outcome was the first major bleeding event (i.e. intracranial hemorrhage, sight threatening bleeding event in the eye, gastrointestinal bleeding, or other serious bleeding) Secondary outcomes included gastrointestinal tract cancer.  A total of 15,480 participants underwent randomization. During a mean follow up of 7.4 years, serious vascular events occurred in a significantly lower percentage of participants in the aspirin group than in the placebo group (658 participants [8.5% vs. 743 [9.6% rate ratio, 0.88; 95% confidence interval [CI] 0.79 to 0.97; P=0.01) In contrast, major bleeding events occurred in 314 participants (4.1% in the aspirin group, as compared with 245 (3.2% in the placebo group (rate ratio, 1.29; 95% CI, 1.09 to 1.52; P=0.003) with most of the excess being gastrointestinal bleeding and other extracranial bleeding. There was no significant difference between the aspirin group and the placebo group in the incidence of gastrointestinal tract cancer (157 participants [2.0% and 158 [2.0% respectively) or all cancers (897 [11.6% and 887 [11.5% long term follow up for these outcomes is planned.  Aspirin use prevented serious vascular events in persons who had diabetes and no evident cardiovascular disease at trial entry, but it also caused major bleeding events. The absolute benefits were largely counterbalanced by the bleeding hazard.

Value, Capital and Nature. Rethinking the foundations of ecological economics
Year: 2018

Ecological economists aim to study the interrelations between ecological and economic systems, with a view to promoting changes towards sustainability. They agree that the nature of global environmental crises is systemic and rooted in economic dynamics. Yet, core economic categories, such as prices, profits, money and their interrelations with ecological destruction, are surprisingly undertheorized. The 'economic' becomes either tied to neoclassical economics or remains neglected. Marxian Political Economy has the potential to address this gap, but is mostly ignored in ecological economics, especially in what it is best at: explaining dynamics of the capitalist system as a whole. This PhD advocates a more systemic and theoretically grounded ecological economics. I find that neoclassical economic reasoning is rooted much deeper in ecological economics than often assumed. I present a critique of the neoclassical underpinnings of ecological economics, and a Marxian alternative. I identify the Marxian understanding of 'value' and 'capital' as the missing core of ecological economics: a realistic understanding of the capitalist system, spelled out from basics in simple and abstract terms. I explain these foundations and integrate them with a system dynamics understanding of global ecological destruction, social crises and barriers to social change. I conclude that ecological economics needs to be grounded in a realistic understanding of capitalism if it aspires to meet its own ambitions. Economic theory and methodology are powerful political tools towards this end: they expose or conceal root causes of social ecological problems and offer better or worse guidance on how to act. Pragmatism about the role of theory and methodology is dangerous, more often than not, because it promotes the reproduction of power relations that prevent, instead of encourage, sustainability transitions. I argue for the need to break with existing prejudices against the Marxian approach and take it seriously as realistic economic theory.

Camera calibration with lens distortion from low rank textures
Venue: CVPR 2011
Year: 2011

We present a simple, accurate, and flexible method to calibrate intrinsic parameters of a camera together with (possibly significant) lens distortion. This new method can work under a wide range of practical scenarios: using multiple images of a known pattern, multiple images of an unknown pattern, single or multiple image(s) of multiple patterns, etc. Moreover, this new method does not rely on extracting any low level features such as corners or edges. It can tolerate considerably large lens distortion, noise, error, illumination and viewpoint change, and still obtain accurate estimation of the camera parameters. The new method leverages on the recent breakthroughs in powerful high dimensional convex optimization tools, especially those for matrix rank minimization and sparse signal recovery. We will show how the camera calibration problem can be formulated as an important extension to principal component pursuit, and solved by similar techniques. We characterize to exactly what extent the parameters can be recovered in case of ambiguity. We verify the efficacy and accuracy of the proposed algorithm with extensive experiments on real images.
Increasing omission of radiation therapy and sentinel node biopsy in elderly patients with early stage, hormone positive breast cancer
Venue: The breast journal
Year: 2019

Prospective evidence demonstrates that there is limited benefit of axillary staging with sentinel lymph node biopsy (SLNB) or radiation therapy (RT) in patients over age 70 with clinical stage I, hormone positive breast cancer. The clinical impact of this literature is unknown. Our hypothesis is that omission of SLNB and RT has increased over time in these patients, and patient and tumor characteristics can predict when omission strategies are used. A single center tumor registry was queried for all patients over age 70 with ER+ Her2/neu negative, clinical T1N0 invasive breast cancer from 2009 to 2017, who underwent breast conservation (n 141) Date of treatment, age, tumor characteristics, use of SLNB, and use of RT were evaluated. The trend of treatment strategy over time was evaluated. Multivariable analysis was performed on the subgroup of patients after publication of the long term follow up CALGB 9343 data1. Patients undergoing treatment with omission of RT and SLNB increased over the study period (P .0006) Patients who did not receive RT were older (78.76 years 5.48 vs 73.37 3.63, P .01) There was no difference between tumor grade and size between uses of RT. Of patients who received SLNB (n 84) only 3 (3.5% had a positive LN. On multivariable analysis of patients who were treated after publication of the CALGB 9343 data (2014 2017) only age was predictive of being treated with RT (OR, 0.77; 95% CI, 0.67 0.88) Omission of both RT and SLNB are increasing in clinical practice in appropriately selected patients. The likelihood that patients are offered omission of these interventions increases with age. Low nodal positivity rates suggest that this strategy may be underutilized. Tumor grade and size were not predictive of omission of RT in this group of low risk patients. Long term data are needed as these approaches are increasingly adopted.
Synthesis of multipass heat exchanger networks using genetic algorithms
Venue: Comput. Chem. Eng.
Year: 2008

In this work, a methodology based on genetic algorithms (GAs) is developed for the optimal synthesis of multipass heat exchanger networks (HENs) The network model is based on a stagewise superstructure, and the problem of finding the optimum number of 1 2 shells in series of multipass heat exchangers is aided by an efficient optimization model that uses the standard F T design method. The proposed methodology allows for proper handling of the trade offs involving energy consumption, number of units, number of 1 2 shells and network area to provide a network with the minimum total annual cost. The results of the examples show that the new approach is able to find more economical networks than those generated by other methods.
Systematic review of universal and targeted workplace interventions for depression
Venue: Occupational and Environmental Medicine
Year: 2017

Depression is increasingly being recognised as a significant mental health problem in the workplace contributing to productivity loss and economic burden to organisations. This paper reviews recently published randomised controlled trials (RCTs) of universal and targeted interventions to reduce depression in the workplace. Studies were identified through searches of EMBASE, MEDLINE/PubMed, PsycINFO, PsycARTICLES Full Text, and Global Health and Social Policy and Practice databases. Studies were included if they included an RCT of a workplace intervention for employees targeting depression as the primary outcome. Twenty two published RCTs investigating interventions utilising various therapeutic approaches were identified. The cognitive behavioural therapy (CBT) approach is the most frequently used in the workplace, while interventions that combine different therapeutic approaches showed the most promising results. A universal intervention in the workplace that combines CBT and coping flexibility recorded the highest effect size (d=1.45 at 4 months' follow up) Most interventions were delivered in group format and showed low attrition rates compared with other delivery formats. Although all studies reviewed were RCTs, the quality of reporting is low. Interventions using different therapeutic approaches with different modes of delivery have been used. Most of these interventions were shown to reduce depression levels among employees in the workplace, particularly those that combine more than one therapeutic approaches.
Analysis of 19th and 20th Century Conservation Key Theories in Relation to Contemporary Adaptive Reuse of Heritage Buildings
Venue: Heritage
Year: 2019

Heritage buildings are important in demonstrating the cultural identities of cities and, consequently, communities throughout the world. In the contemporary era, adaptive reuse has been considered as a strategy for protecting these buildings for both present and future generations. At present, the 19th and 20th century conservation and restoration theories are the backbone of the contemporary adaptation movement by introducing different forms of adaptive reuse over time. These theories revealed how the prioritization system for protecting heritage buildings has changed from a value base to technological needs and user demands. These theories have become theoretical guidelines and policies under modern development. However, these theories are less considered in the contemporary practice of adaptive reuse, and thus remain as theoretical guidelines and policies that are still being developed periodically in the national and international levels. The main aim of this study is to review and critically analyze principal 19th and 20th century theories of conservation, restoration, and adaptive reuse of heritage buildings in order to provide a holistic view of their application, aspects of which may be incorporated in future research, practice, and discussion on the subject. For this paper, these key theories are critically reviewed, analyzed, and discussed, contributing to the study of contemporary practice of adaptive reuse. A summary of the analysis of all key theories is presented. The analysis of the theories presents the evolution of different approaches to adaptive reuse of heritage buildings over time and shows the role of theories in the establishment of international conservation policies. The analysis further reveals the existing gap between theory and practice in contemporary adaptive reuse practice.

Venue: 2015 International Conference on Information and Communication Technology Research (ICTRC)
Year: 2015

This paper proposes a modified hybrid method for WSN localization that combines Received Signal Strength (RSS) and Direction of Arrival (DOA) estimation based on MUSIC (Multiple Signal Classification) using circular antenna array with smoothing capability. Simulation results proves the enhanced performance obtained using the proposed hybrid method. This takes the form of successful detection of a mixture of correlated and uncorrelated signals at a higher accuracy and lower Root Mean Square Error (RMSE) in comparison with conventional method.
b Sitosterol 2 hydroxypropyl b cyclodextrin inclusion complex: Characterization and inhibitory effect on adipogenesis in 3T3 L1 pre adipocytes
Venue: Steroids
Year: 2018

HIGHLIGHTSSit HP &bgr; CD inclusion complex was prepared using the grinding method.The formation of Sit HP &bgr; CD complex was confirmed by DSC, TLC, NMR, and ROESY.Sit HP &bgr; CD complex reduced intracellular lipid accumulation in 3T3 L1 cells.Sit HP &bgr; CD complex had a higher inhibitory effect on adipogenesis than Sit.  Sitosterol (Sit) has been used as a functional food additive. Among its many beneficial effects, this phytosterol plays a role in controlling obesity by inhibiting the adipogenesis process of pre adipocytes. However, the highly lipophilic character of Sit limits its bioavailability. In the present study, 2 hydroxypropyl &bgr; cyclodextrin (HP &bgr; CD) was used to form a complex with Sit, namely the Sit HP &bgr; CD inclusion complex, and the inhibitory effect of this complex on adipogenesis in the 3T3 L1 pre adipocyte cell line was investigated. The results of DSC, TLC, 1H NMR spectroscopy, and 2D ROESY showed that the Sit HP &bgr; CD inclusion complex was successfully synthesized. In addition, the inhibitory effect of the Sit HP &bgr; CD inclusion complex on adipogenesis was evaluated using the Oil Red O staining method and western blot analysis after a 14 day adipogenesis induction in 3T3 L1 pre adipocytes. The results showed that the Sit HP &bgr; CD inclusion complex had a higher efficiency than Sit in reducing intracellular lipid accumulation and the expression levels of PPAR&ggr; and FAS in 3T3 L1 cells, suggesting that the inhibitory effect on adipogenesis was improved by the formation of the Sit and HP &bgr; CD complex.

Year: 2019

Harvest development of farming field assumes a significant job. According to customary framework, loss of nourishment is principally because of contaminated harvests, which moderately diminishes generation amount. In this manner, programmed framework identification of plant maladies is a basic research point as it might demonstrate benefits in observing enormous fields of harvest; framework identifies manifestations of infections as they show up on plant leaves. The framework is a product answer for recognition and grouping of plant leaf illnesses. The system is to reduce the utilization of pesticides in agricultural field and moreover increase the quality and measure of yield creation. This paper investigates leaf malady recognition and order utilizing picture handling systems and furthermore we propose ANN calculations to foresee the contaminated region of leaves.

Development of high efficiency VRF systems under partial heat load for commercial buildings
Year: 2016

VRF systems in commercial buildings are mostly operated under less than 50% heat load through a year, even if the capacity is optimally selected. Therefore it is important to improve its performance under low heat load condition. For this purpose, innovative energy saving A/C controller and compressor were developed in order to enable an optimum operation under low heat load conditions in buildings. These technologies were applied to new developed VRFs "VRV X" and these new VRF products have been launched since March, 2015 in Japan. The partial heat load performance tests of the conventional VRFs and new VRFs were conducted by air enthalpy method. This report shows the operation states and the EER/COP of the new VRFs in comparison with those of the conventional VRFs by the laboratory tests in the test facility. And the seasonal average EER/COP (not SEER/SCOP) of these VRFs was predicted by combining the EER/COP of the VRFs obtained by the laboratory tests and the annual variations of operating conditions in the model building.
Personal digital archiving for journalists: a "private" solution to a public problem
Venue: Libr. Hi Tech
Year: 2018

The purpose of this paper is to encourage librarians to teach digital archiving practices to journalists as a way of giving journalists the skills they need to save their work for future use and to facilitate the preservation of journalism for posterity.  The author has reviewed the personal digital archiving literature and analyzed how it might be specifically tailored to the unique needs of journalists.  Daily journalism has traditionally been preserved by libraries in the form of newspapers and magazines housed in library periodicals departments. Now that nearly all journalism is published online and libraries generally only have access via temporary subscriptions, libraries are prevented from doing any kind of traditional preservation work (e.g. storing copies locally) In the future, this lack of local preservation may lead to a shortage of early twenty first century primary source material for historians.  The needs of journalists do vary greatly based on the nature and format of their work and its publication venue, making it difficult to offer a single set of standards or recommendations.  While personal digital archiving advocates have generally interpreted the word "personal" to be synonymous with "private," this paper points to the need to expand the concept to include professional activities, particularly in light of the prevalence of telecommuting and freelance work arrangements, and the lack of support and training received by remote workers and independent contractors.
Six Lessons for a Cogent Science of Implicit Bias and Its Criticism
Venue: Perspectives on psychological science a journal of the Association for Psychological Science
Year: 2019

Skepticism about the explanatory value of implicit bias in understanding social discrimination has grown considerably. The current article argues that both the dominant narrative about implicit bias as well as extant criticism are based on a selective focus on particular findings that fails to consider the broader literature on attitudes and implicit measures. To provide a basis to move forward, the current article discusses six lessons for a cogent science of implicit bias: (a) There is no evidence that people are unaware of the mental contents underlying their implicit biases; (b) conceptual correspondence is essential for interpretations of dissociations between implicit and explicit bias; (c) there is no basis to expect strong unconditional relations between implicit bias and behavior; (d) implicit bias is less (not more) stable over time than explicit bias; (e) context matters fundamentally for the outcomes obtained with implicit bias measures; and (f) implicit measurement scores do not provide process pure reflections of bias. The six lessons provide guidance for research that aims to provide more compelling evidence for the properties of implicit bias. At the same time, they suggest that extant criticism does not justify the conclusion that implicit bias is irrelevant for the understanding of social discrimination.
