Testing and improving shear viscous phase space correction models
Year: 2017

Comparison of hydrodynamic calculations with experimental data inevitably requires a model for converting the fluid to particles. In this work, nonlinear $2\to 2$ kinetic theory is used to assess the overall accuracy of various shear viscous fluid to particle conversion models, such as the quadratic Grad corrections, the Strickland Romatschke (SR) ansatz, self consistent shear corrections from linearized kinetic theory, and the correction from the relaxation time approach. We test how well the conversion models can reconstruct, using solely the hydrodynamic fields computed from the transport, the phase space density for a massless one component gas undergoing a 0+1D longitudinal boost invariant expansion with approximately constant specific shear viscosity in the range \sim 0.03 \le \eta/s \le \sim 0.2$ In general we find that at early times the SR form is the most accurate, whereas at late times or for small \eta/s\sim 0.05$ the self consistent corrections from kinetic theory perform the best. In addition, we show that the reconstruction accuracy of additive shear viscous $f f_{\rm eq} \delta f$ models dramatically improves if one ensures, through "exponentiation" that $f$ is always positive. We also illustrate how even more accurate viscous \delta f$ models can be constructed if one includes information about the past evolution of the system via the first time derivative of hydrodynamic fields. Such time derivatives are readily available in hydrodynamic simulations, though usually not included in the output.
One to Many Single Entity Electrochemistry Biosensing for Ultrasensitive Detection of microRNA.
Venue: Analytical chemistry
Year: 2019

Single entity electrochemistry (SEEC) a promising method for biosensing, has an intrinsic limitation on sensitivity since at most one colliding entity can be successfully triggered by one target. Here, we take advantage of one to many (1:n) signal amplification to develop a new single entity electrochemistry biosensing (SEECBS) integrating satellite magnetic nanoparticle (MN) DNA Pt nanoparticle (NP) conjugates, duplex specific nuclease (DSN) assisted Pt NPs releasing with stabilization and effective collision of small sized and nearly naked Pt NPs. Compared with conventional SEECBS, the 1:n SEECBS can successfully enrich ~2 nM Pt NPs by adding 50 aM microRNA (miRNA) in other words, ~4x107 Pt NPs can be triggered by one target. The proposed SEECBS allows the detection of 47 aM miRNA 21, nearly 6 orders of magnitude lower than the previous work, and discrimination of non target miRNAs containing even single nucleotide mismatch. Besides, this method has also been successfully demonstrated for quantification of miRNA in different cell lines. Therefore, the proposed method holds great potential for the application of SEECBS in early diagnosis and prognosis monitoring of cancer.
Dissociative subtype of posttraumatic stress disorder or PTSD with comorbid dissociative disorders: Comparative evaluation of clinical profiles.
Venue: Psychological trauma theory, research, practice and policy
Year: 2019

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (American Psychiatric Association, 2013) introduced a dissociative subtype for patients with posttraumatic stress disorder (PTSD) and depersonalization and/or derealization symptoms. Despite high comorbidity rates between PTSD and dissociative disorders (DDs) research has not paid attention to the differentiation or overlap between the dissociative subtype of PTSD and DDs. This raises a question: To what extent do patients with dissociative PTSD differ from patients with PTSD and comorbid DDs? METHOD We compared three groups of complex patients with trauma related disorders and/or personality disorders (n 150) a dissociative PTSD, a nondissociative PTSD, and a non PTSD group of patients with mainly personality disorders. We used structured clinical interviews and self administered questionnaires on dissociative symptoms and disorders, personality disorders, trauma histories, depression, anxiety, and general psychopathology. The Dissociative Experiences Scale (DES; =20) and the depersonalization/derealization subscale of the DES were used for differentiating dissociative PTSD from nondissociative PTSD.  Of all patients, 33% met criteria for dissociative PTSD. More than half of the dissociative PTSD patients (54% met criteria for one or more DDs; using the depersonalization/derealization subscale of the DES, even 66% had a comorbid DD. But also of the non PTSD patients, 24% had a mean DES score of =20. There were no symptomatic differences (e.g. depression and anxiety) between dissociative PTSD with and without comorbid DDs.  Overlap between dissociative PTSD and DD is large and we recommend replication of previous studies, using structured clinical assessment of DDs.

UWB Assisted High Precision Positioning in a UTM Prototype
Venue: 2020 IEEE Topical Conference on Wireless Sensors and Sensor Networks (WiSNeT)
Year: 2020

A high precision positioning prototype suitable for the Unmanned Aircraft System Traffic Management (UTM) system is proposed. Comprised of Global Positioning System (GPS) Ultra wideband (UWB) and Long Range (LoRa) WAN capabilities, our prototype effectively improves GPS accuracy by utilizing high precision UWB distance measurement. A set of calibration procedures can reduce the error of UWB distance measurement within 10cm accuracy. Moreover, a novel cost function is proposed so that the longitude, latitude, and relative height errors of GPS can be effectively improved, with relative altitude error reduced from 4. 03m to 1. 74m in particular. Finally, our UWB assisted positioning prototype significantly enhances GPS localization accuracy. The outdoor relative position error between devices under test (DUTs) can be reduced from 6 m to within 10 cm.

The culture of scientific research
Venue: F1000Research
Year: 2015

In 2014, the UK based Nuffield Council on Bioethics carried out a series of engagement activities, including an online survey to which 970 people responded, and 15 discussion events at universities around the UK to explore the culture of research in the UK and its effect on ethical conduct in science and the quality of research. The findings of the project were published in December 2014 and the main points are summarised here. We found that scientists are motivated in their work to find out more about the world and to benefit society, and that they believe collaboration, multidisciplinarity, openness and creativity are important for the production of high quality science. However, in some cases, our findings suggest, the culture of research in higher education institutions does not support or encourage these goals or activities. For example, high levels of competition and perceptions about how scientists are assessed for jobs and funding are reportedly contributing to a loss of creativity in science, less collaboration and poor research practices. The project led to suggestions for action for funding bodies, research institutions, publishers and editors, professional bodies and individual researchers.
Stochastic Optimal Power Flow Applied in Day Ahead Planning of Isolated Microgrids
Venue: 2020 IEEE Power Energy Society General Meeting (PESGM)
Year: 2020

Due to the growing demand for energy in the last decades, the electric power system has been facing challenges to supply the power consumed by population. In this sense, isolated microgrids have emerged as a viable alternative based on the use of local energy resources to feed hard to reach areas. In this context, this paper develops a day ahead energy based on optimal power flow for an isolated microgrid in Brazil equipped with storage system, backup generation and renewable resources. The renewable resource available in the studied microgrid is the photovoltaic solar energy, which presents an intermittent behavior, and so it is modeled by a probability density function in the proposed OPF formulation. The storage system represents approximately 52% of the total microgrid investment. Considering that, the objective function of the OPF incorporates the costs associated to the life cycle of the storage system and the fuel consumption with the backup generation, as well as, a stochastic model to estimate the costs of the photovoltaic solar energy. The proposed formulation was solved using Differential Evolution algorithm to obtain a minimal generation cost considering the load profile of a typical day.
Mining Meaning from Wikipedia
Venue: Int. J. Hum. Comput. Stud.
Year: 2009

Wikipedia is a goldmine of information; not just for its many readers, but also for the growing community of researchers who recognize it as a resource of exceptional scale and utility. It represents a vast investment of manual effort and judgment: a huge, constantly evolving tapestry of concepts and relations that is being applied to a host of tasks. This article provides a comprehensive description of this work. It focuses on research that extracts and makes use of the concepts, relations, facts and descriptions found in Wikipedia, and organizes the work into four broad categories: applying Wikipedia to natural language processing; using it to facilitate information retrieval and information extraction; and as a resource for ontology building. The article addresses how Wikipedia is being used as is, how it is being improved and adapted, and how it is being combined with other structures to create entirely new resources. We identify the research groups and individuals involved, and how their work has developed in the last few years. We provide a comprehensive list of the open source software they have produced.
A Common Pesticide Decreases Foraging Success and Survival in Honey Bees
Venue: Science
Year: 2012

Bad News for Bees Neonicotinoid insecticides were introduced in the early 1990s and have become one of the most widely used crop pesticides in the world. These compounds act on the insect central nervous system, and they have been shown to be persistent in the environment and in plant tissues. Recently, there have been controversial connections made between neonicotinoids and pollinator deaths, but the mechanisms underlying these potential deaths have remained unknown. Whitehorn et al. (p. 351, published online 29 March) exposed developing colonies of bumble bees to low levels of the neonicotinoid imidacloprid and then released them to forage under natural conditions. Treated colonies displayed reduced colony growth and less reproductive success, and they produced significantly fewer queens to found subsequent generations. Henry et al. (p. 348, published online 29 March) documented the effects of low dose, nonlethal intoxication of another widely used neonicotinoid, thiamethoxam, on wild foraging honey bees. Radio frequency identification tags were used to determine navigation success of treated foragers, which suggested that their homing success was much reduced relative to untreated foragers. Honey bees cannot find their way home after exposure to sublethal doses of a widely used insecticide. Nonlethal exposure of honey bees to thiamethoxam (neonicotinoid systemic pesticide) causes high mortality due to homing failure at levels that could put a colony at risk of collapse. Simulated exposure events on free ranging foragers labeled with a radio frequency identification tag suggest that homing is impaired by thiamethoxam intoxication. These experiments offer new insights into the consequences of common neonicotinoid pesticides used worldwide.
How good are clinical severity and outcome measures for psoriasis? quantitative evaluation in a systematic review.
Venue: The Journal of investigative dermatology
Year: 2010

A large number of clinical measures of psoriasis are used in clinical trials and daily practice. These measures lack uniformity and validation. However, valid outcome and severity measures for psoriasis are a prerequisite for fully informative clinical research and evidence based medicine. The purpose of this study was to identify all clinical measures of psoriasis severity and outcome in use and to evaluate the quality of these measures using clinimetric criteria; we identified 53 separate clinical measures, which were regrouped into 11 measures for quality analysis. No measure could be scored on all items used in the clinimetric analysis. The Lattice System Physician's Global Assessment and Physician's Global Assessment were most highly noted. We conclude that none of the psoriasis measures is adequately validated. The Psoriasis Area and Severity Index is the most commonly used clinical measure in research, but it has substantial limitations such as low response distribution, no consensus on interpretability, and low responsiveness in mild disease. Nevertheless, because of its widespread use the Psoriasis Area and Severity Index permits some degree of comparison of results among clinical trials. Overall, no best instrument was identified, and different situations may call for different measures.
The readiness of cooperatives in West Java to join an inclusive business platform: KUKM Ecobiz
Year: 2019

Cooperatives are expected to contribute to society's welfare. However, in West Java, cooperatives have not been able to optimise their potential due to lack of collaborative cooperation with other stakeholders within the scope of inclusive business. To realise the cooperative's potential, KUKM Ecobiz was introduced as an inclusive business platform to increase multi stakeholder collaboration. This study explores the readiness of cooperatives in West Java to join an inclusive business platform, KUKM Ecobiz, by identifying the West Java cooperatives' infrastructures and measuring their willingness to collaborate with other parties through FGD, observation, LFA and survey. The result shows that readiness to join the inclusive business platform is still low, although, based on the survey results; the willingness of West Java cooperatives to collaborate is high. However, the West Java cooperatives' infrastructure is still significantly different and diverse among regions, and their interaction is still low because some factors like the mastery of technology, education, and facilities and the capability of human resources are still limited.
Acute change in anterior cingulate cortex GABA, but not glutamine/glutamate, mediates antidepressant response to citalopram
Venue: Psychiatry Research: Neuroimaging
Year: 2017

Little is known about the acute effects of antidepressant treatments on brain glutamate and gamma amino butyric acid (GABA) levels, and their association with clinical response. Using proton magnetic resonance spectroscopy (1H MRS) we examined longitudinally the effects of citalopram on glutamine/glutamate ratios and GABA levels in the pregenual anterior cingulate cortex (pgACC) of individuals with major depressive disorder (MDD) We acquired 1H MRS scans at baseline and at days 3, 7, and 42 of citalopram treatment in nineteen unmedicated individuals with MDD. Ten age and sex matched non depressed comparison individuals were scanned once. The association between 1) baseline metabolites and 2) change in metabolites from baseline to each time point and clinical response (change in Montgomery Asberg Depression Rating Scale (MADRS) score from baseline to day 42) was assessed by longitudinal regression analysis using generalized estimating equations. Contrary to our hypotheses, no significant associations emerged between glutamate metabolites and clinical response; however, greater increases (or smaller decreases) in pgACC GABA levels from baseline to days 3 and 7 of citalopram treatment were significantly associated with clinical response. These findings suggest that an acute change in GABA levels in pgACC predicts, and possibly mediates, later clinical response to citalopram treatment in individuals with MDD.

The role of boards in clinical governance: activities and attitudes among members of public health service boards in Victoria.
Venue: Australian health review a publication of the Australian Hospital Association
Year: 2013

To determine the nature and extent of governance activities by health service boards in relation to quality and safety of care and to gauge the expertise and perspectives of board members in this area.  This study used an online and postal survey of the Board Chair, Quality Committee Chair and two randomly selected members from the boards of all 85 health services in Victoria. Seventy percent (233/332) of members surveyed responded and 96% (82/85) of boards had at least one member respond.  Most boards had quality performance as a standing item on meeting agendas (79% and reviewed data on medication errors and hospital acquired infections at least quarterly (77% Fewer boards benchmarked their service's quality performance against external comparators (50% or offered board members formal training on quality (53% Eighty two percent of board members identified quality as a top priority for board oversight, yet members generally considered their boards to be a relatively minor force in shaping the quality of care. There was a positive correlation between the size of health services (total budget, inpatient separations) and their board's level of engagement in quality related activities. Ninety percent of board members indicated that additional training in quality and safety would be 'moderately useful' or 'very useful' Almost every respondent believed the overall quality of care their service delivered was as good as, or better than, the typical Victorian health service.  Collectively, health service boards are engaged in an impressive range of clinical governance activities. However, the extent of engagement is uneven across boards, certain knowledge deficits are evident and there was wide agreement among board members that further training in quality related issues would be useful.
Associations between Childhood Sexual Abuse and Sexual Well being in Adulthood: A Systematic Literature Review
Venue: Journal of child sexual abuse
Year: 2020

Child sexual abuse (CSA) tends to occur in close relationships and involves sexual acts and betrayal. Thus, it is thought to affect sexual well being in adulthood more so than any other form of childhood trauma. Research conducted over the last decade resulted in an impressive diversity of evidence reporting that CSA may be related to greater sexual dysfunction and lower sexual satisfaction as an adult, but also to higher levels of sexual compulsivity and sexual risk behaviors. Some studies also found no significant association between CSA and adult sexual well being. Faced with these mixed results, understanding how CSA may affect sexual well being in adulthood remains challenging for clinicians and researchers. The aim of this comprehensive literature review was to synthesize the empirical studies published in the last five years documenting the associations between CSA and several indicators of sexual well being in adults excluding risky sexual behaviors. The literature search yielded 18 eligible studies which mainly examined five domains of sexual outcomes of CSA: sexual function, sexual satisfaction, sex related cognitions, sexual behaviors and affective components of sexuality. Findings suggest that CSA is not unanimously related to all domains of sexual well being, but rather, that associations are largely a function of the presence of other comorbidities or nature of the sample. Moreover, men are still significantly underrepresented in reviewed studies. Implications of the findings will be discussed in light of their relevance for clinicians and for researchers about gaps in current literature need to be filled.
