From Box Algebra to Interval Temporal Logic
Authors: Klaudel Hanna , Koutny Maciej , Duan Zhenhua , Moszkowski Ben
Published: July 2019

In this paper, we further develop a recently introduced semantic link between temporal logics and Petri nets. We focus on two specific formalisms, Interval Temporal Logic (ITL) and Box Algebra (BA), which are closely related by their compositional approach to constructing system descriptions. The overall goal of our investigation is to translate Petri nets into behaviourally equivalent logical formulas. As a result, the analysis of system properties can be carried out using either of the two formalisms, exploiting their respective strengths and powerful tool support.

The contribution of this paper is twofold. First, we extend the existing translation from BA to ITL, by removing restrictions concerning the way control flow of concurrent system is modelled, and by allowing a fully general synchronisation operator. Second, we strengthen the notion of equivalence between a Petri net and the corresponding logical formula by proving such an equivalence at the level of transition-based executions of Petri nets rather than just by looking at their labels. We also show that the complexity of the proposed translation compares favourably with the complexity of the translation from BA expressions to Petri nets.
Dementia Risk Elevates Brain Activity During Memory Retrieval: A Functional MRI Analysis of Middle Aged and Older Adults
Authors: McDonough Ian M. , Letang Sarah K. , Stinson Elizabeth A.
Published: July 2019

Longitudinal research suggests that genetic, lifestyle, and environmental factors enhance one’s risk for developing Alzheimer’s disease and related dementias (ADRD). However, it is not known how an accumulation of such factors impact brain functioning. One barrier to this research is that increased risk for ADRD affects the cerebrovascular system and, therefore, alters the link between neural activity and the fMRI BOLD signal. To better interpret fMRI findings, several steps were taken to adjust fMRI activity thereby reducing such cerebrovascular effects. We hypothesized that as the number of ADRD risk factors increase, brain regions within the medial temporal lobes and the default mode network would exhibit altered brain activity during an episodic memory retrieval task. Middle-aged and older adults (aged 50–74) free of dementia were recruited with varying levels of risk and underwent a neuropsychological battery and fMRI. In the memory task, participants viewed a pair of pictures. In an alternative-forced-choice test, participants viewed a picture cue and had to determine which of four pictures was paired with the cue. Increased dementia risk was positively associated with brain activity in regions of interest within the default mode network, the hippocampus, and the entorhinal cortex during memory retrieval. Whole-brain analyses revealed additional positive associations in prefrontal and occipito-temporal cortices. Risk factors most contributing to these elevated levels of brain activity included hypertension, diabetes, obesity, and cholesterol. We also ruled out confounds due to in-scanner performance and premorbid ability. Cumulative risk might represent early signs of burnout in brain regions underlying episodic memory.
A Systematic Review of Meta-Analyses that Evaluate Risk Factors for Dementia to Evaluate the Quantity, Quality, and Global Representativeness of Evidence
Authors: Anstey Kaarin J. , Ee Nicole , Eramudugolla Ranmalee , Jagger Carol , Peters Ruth
Published: July 2019

Background:

The translation of evidence on dementia risk factors into clinical advice requires careful evaluation of the methodology and scope of data from which risk estimates are obtained.

Objective:

To evaluate the quantity, quality, and representativeness of evidence, we conducted a review of reviews of risk factors for Alzheimer’s disease (AD), Vascular dementia (VaD), and Any Dementia.

Methods:

PubMed, Cochrane library, and the Global Index Medicus were searched to identify meta-analyses of observational studies of risk factors for AD, VaD, and Any Dementia. PROSPERO CRD42017053920.

Results:

Meta-analysis data were available for 34 risk factors for AD, 26 risk factors for Any Dementia and eight for VaD. Quality of evidence varied greatly in terms of the number of contributing studies, whether data on midlife exposure was available, and consistency of measures. The most evidence was available for cardiovascular risk factors. The most geographically representative evidence (five of six global regions) was available for alcohol, physical activity, diabetes, high midlife BMI, antihypertensives, and motor function. Evidence from Australia/Oceana or Africa was limited. With the exception of diabetes, meta-analysis data were unavailable from Latin America/Caribbean. Midlife specific data were only available for cholesterol and arthritis.

Conclusion:

There is a lack of midlife specific data, limited data on VaD, and a lack of geographical representation for many risk factors for dementia. The quality, quantity, and representativeness of evidence needs to be considered before recommendations are made about the relevance of risk factors in mid- or late-life or for dementia subtypes.
Can Subjective Memory Complaints Identify Aβ Positive and Aβ Negative Amnestic Mild Cognitive Impairment Patients?
Authors: Mendes Tiago , Cardoso Sandra , Guerreiro Manuela , Maroco João , Silva Dina , Alves Luísa , Schmand Ben , Gerardo Bianca , Lima Marisa , Santana Isabel , de Mendonça Alexandre
Published: July 2019

Background:

The use of biomarkers, in particular amyloid-β (Aβ) changes, has allowed the possibility to identify patients with subjective memory complaints (SMCs) and amnestic mild cognitive impairment (aMCI) who suffer from Alzheimer’s disease (AD). Since it is unfeasible that all patients with aMCI could presently undergo biomarkers assessment, it would be important that SMCs might contribute to identify the aMCI patients who have AD amyloid pathology.

Objectives:

To know whether aMCI patients with amyloid biomarkers (Aβ+) present greater SMCs as compared to those without amyloid biomarkers (Aβ-).

Methods:

Participants were selected from a cohort of nondemented patients with cognitive complaints and a comprehensive neuropsychological evaluation, on the basis of 1) diagnosis of aMCI; 2) detailed assessment of memory difficulties with the SMC Scale; and 3) known amyloid status. The amyloid status was determined on the basis of either CSF Aβ1–42 concentration or amyloid PET imaging.

Results:

Of the 176 patients with aMCI studied, 90 were Aβ+ and 86 were Aβ-. The two groups did not differ in terms of age, gender, and education. The SMC total score was not significantly different in the Aβ+ aMCI patients (9.48±4.18) when compared to the Aβ- aMCI patients (10.52±4.57). The Aβ+ aMCI patients had lower scores on the MMSE and memory/learning tests, but not on the Geriatric Depression Scale, when comparing to the Aβ- aMCI patients.

Conclusions:

Evaluating SMCs does not seem helpful to identify, among patients with aMCI, those who have AD.
Highly Elevated Cerebrospinal Fluid Total Tau Level Reflects Higher Likelihood of Non-Amnestic Subtype of Alzheimer’s Disease
Authors: Pillai Jagan A. , Bonner-Jackson Aaron , Bekris Lynn M. , Safar Jiri , Bena Jim , Leverenz James B.
Published: July 2019

Background:

Cerebrospinal fluid (CSF) levels of total tau (t-tau) protein are thought to reflect the intensity of the neuronal damage in neurodegeneration, including Alzheimer’s disease (AD). The recent link of CSF t-tau to rapidly progressive AD raises the question among other AD clinical variants regarding CSF t-tau. We investigated the clinical phenotypes of AD patients with varying CSF t-tau levels.

Objective:

We tested the hypothesis that highly elevated CSF t-tau level would have a higher likelihood of presenting with atypical non-amnestic variants of AD.

Methods:

Retrospective comparative case study of 97 patients evaluated in a memory clinic with clinical presentation and CSF biomarkers consistent with AD. We compared the age, sex, education, APOE ɛ 4 status, Montreal Cognitive Assessment (MoCA) score, clinical phenotype, and MRI volumetric measures by CSF t-tau quartile at baseline. Multivariable logistic regression models were used to evaluate if CSF t-tau levels predict non-amnestic presentations controlling for covariates.

Results:

Non-amnestic AD had a higher median CSF t-tau level compared to amnestic-AD ( p = 0.014). Each 50 pg/ml increase in CSF t-tau was associated with an increase in the odds of having a non-amnestic presentation (7.4%) and aphasia (10.6 %) as the initial presenting symptom even after taking into account; age, sex, education, APOE ɛ 4, MoCA, and CSF Aβ42. Logopenic AD had higher t-tau and p-tau levels compared to other variants.

Conclusions:

Highly elevated CSF t-tau levels could indicate more cortical involvement presenting with early non-amnestic symptoms in atypical AD subtypes, particularly in the logopenic variant.
Effect of paired-pulse stimulus parameters on the two phases of short interval intracortical inhibition in the quadriceps muscle group
Authors: Krishnan Chandramouli
Published: July 2019

Background:

Short interval intracortical inhibition (SICI) is commonly used to assess inhibition in the motor cortex and is known to be affected by the paired-pulse stimulus parameters (i.e., interstimulus interval [ISI], conditioning stimulus intensity [CSI] and test stimulus intensity [TSI]) used during testing. While the effects of stimulus parameters are well-studied in the upper-extremity, evidence in the lower-extremity is lacking.

Objective:

To comprehensively examine the effects of alterations in paired-pulse stimulus parameters on the two phases of SICI in the quadriceps muscle group.

Methods:

Seventeen adults (8 males, 9 females) volunteered to participate in this study. SICI was examined over a range of CSIs (70–90% active motor threshold [AMT]), TSIs (100–140% AMT), and ISIs (1.0–3.0 ms) using both EMG and torque responses elicited by transcranial magnetic stimulation (TMS).

Results:

The results indicated that SICI at 1.0 ms ISI was best revealed with a CSI of 70% and TSI ≥110% AMT, whereas SICI at 2.5 ms ISI was best revealed with a CSI of 80–90% and a TSI of ≥130% AMT. Unlike upper-extremity muscles, evaluating SICI with a CSI of 70% AMT and an ISI of 1.0 ms produced the greatest inhibition for all TSIs. In general, inhibitory effects were contaminated by facilitatory effects when using a TSI of 100% AMT.

Conclusions:

The amount of inhibition was dependent on the stimulation parameters used during testing. A CSI of 70% AMT, ISI of 1.0 ms, and TSI of ≥110% AMT appear to be optimal for measuring SICI in the quadriceps muscle; however, other parameters can be used if careful consideration is given to the described interaction between the parameters.

Authors: Ben Ren-Jy , Jao Jo-Chi , Chang Chiung-Yun , Tzeng Jiun-Siang , Hwang Lain-Chyr , Chen Po-Chou
Published: July 2019

BACKGROUND:

Arterial embolism is a major cause of ischemic stroke. Currently, digital subtraction angiography (DSA) is the gold standard in clinical arterial embolization examinations. However, it is invasive and risky.

OBJECTIVE:

This study aims to longitudinally assess the progression of carotid artery embolism in middle cerebral artery occlusion animal model (MCAO) using magnetic resonance imaging (MRI) techniques.

METHODS:

Turbo spin echo (TSE), time of flight magnetic resonance angiography (TOF-MRA) and diffusion weighted magnetic resonance imaging (DWI) were used to evaluate the image characteristics of cerebral tissues at 1, 2, 3, 7, 14, 21 and 28 days after MCAO microsurgery on Sprague-Dawley (SD) rats. Quantitative analysis was performed and compared in MCAO hemisphere and contralateral normal hemisphere. Furthermore, pathologic section using triphenyl tetrazolium chloride (TTC) stain was performed as well.

RESULTS:

TOF-MRA showed carotid signal void in the embolism side, which is evidence of artery occlusion. The used MRI techniques showed that edema gradually dissipated within one week, but there was no significant change afterwards. The time-varying signal intensity of MRI techniques in MCAO hemisphere changed significantly, but there were no significant changes in contralateral normal hemisphere. Cerebral injury was also confirmed by analysis of pathology images.

CONCLUSIONS:

The MCAO animal model was successfully established on SD rats using the microsurgery to assess arterial embolization of intracranial tissue injury.

Authors: Tao Chao , Chen Ke , Han Lin , Peng Yulan , Li Cheng , Hua Zhan , Lin Jiangli
Published: July 2019

BACKGROUND:

Breast cancer has the highest cancer prevalence rate among the women worldwide. Early detection of breast cancer is crucial for successful treatment and reducing cancer mortality rate. However, tumor detection of breast ultrasound (US) image is still a challenging work in computer-aided diagnosis (CAD).

OBJECTIVE:

This study aims to develop a novel automated algorithm for breast tumor detection based on deep learning.

METHODS:

We proposed a new deep learning network named One-step model which have one input and two outputs, the first one was the segmentation result and the other one was used for false-positive reduction. The proposed One-step model includes three key components: Base-net, Seg-net, and Cls-net based on Anchor Box. The model chose DenseNet to construct Base-net, the decoder part of RefineNet as Seg-net, and connected several middle layers of Base-net and Seg-net to Cls-net. From the first output acquired by Base-net and Seg-net, the model detected a series of suspicious lesion regions. Then the second output from the Cls-net was used to recognize and reduce the false-positive regions.

RESULTS:

Experimental results showed that the new model achieved competitive detection result with 90.78% F1 score, which was 8.55% higher than Single Shot MultiBox Detector (SSD) method. In addition, running new model is also computational efficient and has comparative cost effect as SSD.

CONCLUSIONS:

We established a novel One-step model which improves location accuracy by generating more precise bounding box via Seg-net and removing false targets by another object detection network (Cls-net). On the other hand, a real-time detection of tumor is achieved by sharing the common Base-net. The experimental results showed that the new model performed well on various irregular and blurred ultrasound images. As a result, this study demonstrated feasibility of applying deep learning scheme to detect breast lesions depicting on US image.

Nonsense, Normative or Necessity: The Purpose of Repeating a Modified Internship for Qualified Paramedics to Move between Australian States: Perspective from One State Service
Authors: Caudle Aaron , Schuwirth Lambert , Sweet Linda
Published: July 2019

Introduction

If a paramedic moves interstate in Australia, they are often required to undertake a local state-specific internship in the state or territory they are moving to. The small differences in roles undertaken between the states and territories are not sufficient to explain this requirement. In order to better understand this expectation, the authors explored the national and organisational cultural factors that could explain its purpose.

Methods

Semi-structured interviews were conducted with six major stakeholders of an internship, and interpreted using organisational and national-cultural dimensions derived from the work of Hofstede, Waisfisz and Minkov.

Results

Seven core themes were identified, layered according to the stakeholders that have the greatest influence over the theme, and discussed using the study's interpretive framework (cultural dimensions). These core themes describe the concerns the respondents had about elements of the paramedic internship, including the culture of the internship, attitudes, education, communication, the profession, the organisation, and recruitment and selection.

Conclusion

The insights gained into the cultural characteristics of the ambulance organisation help us to better understand the need for the internship. From a cultural perspective, paramedics need to be able to balance risk aversion (policy/procedure) with risk taking (unpredictable work demands); structure (militaristic) with independence (autonomy); a hierarchy-based power relationship and a competency-based power relationship and, finally, indulgence (socialisation for organisational acceptance) with restraint (becoming a professional). This balancing of judgement and actions is extremely complex, delicate and organisation-specific, thus explaining the importance for the individual organisation of having a prolonged observation period during which ‘a feel’ for these ‘balances’ can be obtained to ensure that the paramedic ‘fits’ into the specific organisation to become ‘one of us’.
Capital Punishment: A Counter Narrative in Islamic Jurisprudence
Authors: Habash Dr. Muhammad
Published: July 2019

There has been a sharp rise in the award of capital punishment in the Muslim world. It has been observed that several of these cases do not result from fair trials and majority of them are based on either political victimization or reprisals for one or the other reason which are linked to the teaching of the Qur’an or Islamic Jurisprudence although Islam and the Qur’anic teachings have nothing to do with such atrocities or unfair legal proceedings. The question is whether the capital punishment has been awarded after a fair trial or it is based on political victimization. It has to be noted here that the God of Islam is very merciful. He has promised a greater reward for the aggrieved person if he chooses to forgive the offender.It means there is a choice in Islam which does not at all encourage capital punishment. In fact, Islamic jurisprudence is not followed and practiced in true letter and sprite. The laws are being misused for self-interest. No fair trials take place and no attempt is made to eradicate the causes of injustices. The teachings of Islam are mainly misunderstood and misinterpreted. We need to comprehend the spirit of Islamic law and find solutions for all such issues that arise because of our lack of true knowledge of Islamic teachings. This paper deals with the problem of executions from a different perspective contrary to what is happening in the Islamic world as far as implementation of Islamic law is concerned.

The creation of Tafsir (exegesis, commentary, interpretation) is indeed the outcome of contemplation of the Qur’anic verses by great scholars often known as MufassirÊn (exegetes). The initial instances of Tafsir can be traced back to the glorious era of Prophet (peace and mercy be upon him) and consequenty Aḥkam ul Qur’an or juristic exegesis (Tafsir al fiqhi) is becoming one of the most important field of the research in Islamic Studies. Muslim jurists especially from the sub-continent have produced remarkable juristic exegesis in the field of Quranic Studies. The purpose of this research is to cover briefly the contributions of Mufassirin in the sub-continent in the field of Juristic implementation of the Holy Qur’an.

INTRODUCCIÓN: Los hábitos bucales no fisiológicos y las maloclusiones constituyen uno de los problemas más relevantes de la Odontología. Los primeros se desarrollan en la infancia, siendo estos un factor etiológico que trae como consecuencia a las segundas, es decir, las maloclusiones. Muchas de las maloclusiones son diagnosticadas de forma errónea o tardía y simplemente quedan sin tratamiento. Las maloclusiones constituyen un verdadero problema para el paciente, ya que estas producen la instalación de algún tipo de malformación dentoesqueletal como mordida abierta, mordida cruzada, apiñamiento dental, gingivitis, problemas estéticos, masticación y baja autoestima. Es por ello que se plantea la necesidad de estudiar los malos hábitos bucales no fisiológicos y su relación con las maloclusiones dentales.

Published: July 2019

La presente investigación constituye una revisión bibliográfica sobre artículos publicados en relación al tratamiento dental del paciente oncológico, siendo quizás uno de los mayores desafíos a los que se puede enfrentar el odontólogo, ya que esta es una situación muy compleja, la cual requiere una atención meticulosa, integral, ordenada y coordinada con la participación de un equipo multidisciplinario. La meta es la curación completa del paciente y con la menor cantidad posible de secuelas que causa la terapia oncológica. Para llegar a esa meta se debe seguir un protocolo de atención odontológico que se divide en tres etapas: antes, durante y después de la terapia oncológica la cual abarca diversos tratamientos. En este trabajo se describirán las atenciones odontológicas de las patologías generadas por la terapia oncológica, también de cómo prevenirlas y tratarlas.

In our study, we dealt with the investigation of attitudes of elementary school pupils towards geography taught in schools which is at the lower education level represented by the school subject with the identical title. This research was carried out in years 2017 and 2018 in three elementary schools located in rural areas of Slovakia. The total average value for the examined components of the attitude among pupils attending grades 5 to 9 was 3.41 (SD = 1.43) which represents slightly positive attitudes of pupils towards Geography subject. Pupils reported that the most interesting geography contents were the topics taught in the 5th grade. As the most difficult they regarded the topics taught in the 6th grade (Regional Geography – Africa, Asia) and in the 7th grade (Regional Geography – Europe); by contrast, they think that the least difficult topics are taught in the 9 th grade (Slovakia). They have most problems remembering the names of mountains, lowlands, rivers and countries. In the investigation of differences in attitudes of pupils towards Geography in individual grades of the lower secondary education the highest average scores were observed among 5th graders (x = 3.58). By contrast, the lowest scores were achieved, surprisingly, by 6th graders (x = 3.27). The average scores of Geography assessment by pupils slightly increased in 6th to 9th grades. The statistical analysis confirmed that the differences between individual grades and between genders as to the average score values achieved by the pupils are not statistically significant.
PENINGKATAN KEMAMPUAN KEPALA SEKOLAH DALAM MENYUSUN PROGRAM SUPERVISI AKADEMIK MELALUI SUPERVISI MANAJERIAL
Authors: Marhendri Marhendri
Published: July 2019

The background of this research is that there are still principals in carrying out academic supervision without a well-structured and well-planned program, so that supervision is carried out if there will only be an assessment or accreditation. The purpose of this study was to improve the ability of principals to develop academic supervision programs through managerial supervision. This research was conducted in a primary school built by researchers in the District of Rakit Kulim, totaling 10 schools. The results of the study showed, in the first cycle, there were only 4 schools or 40% of principals who were able to arrange academic supervision programs properly and correctly, while 6 schools or 60% of principals had not been able to arrange the program properly. In the second cycle, the indicator of success in mentoring and managerial supervision in the second cycle was 80%. There are already 8 built primary schools that have completed the academic supervision program properly and correctly. While 2 elementary schools still have a number of programs that need to be improved, but have been able to show the results of the academic supervision program that was compiled. Can researchers conclude that by implementing managerial supervision can improve the ability of school principals in preparing academic supervision programs in primary schools built by Rakit Kulim District.

Based on the results of a survey conducted by the World Health Organization (WHO) in 2012, the number of active smokers in the world has reached more than 1 billion people. This number is expected to continue to increase given the high prevalence of world cigarette consumption rates, while in Indonesia it is found that almost every year the number of smokers is increasing. Cigarettes containing chemicals including carbon monoxide, nicotine, tar, ammonia, arsenic, cyanide and lead (Pb) The main effect is lead that is inhaled and enters the respiratory system will also circulate throughout the tissues and organs of the body. More than 90% of lead metal absorbed by blood binds to red blood cells and results in a disruption in the process of hemoglobin synthesis. The purpose of this study is to determine the level of lead metal toxicity with an overview of smear preparations in the blood of active smokers. The research method with simple random sampling, samples taken capillary blood and making blood smear preparations that were examined with a microscope while examining the metal in the urine using Atomic Absorption Spectrophotometer (AAS). The results of the study of lead content in urine of active smokers found that the high is 0.384 mg / dl and the low lead level is 0.002 mg / dl positive containing lead in the urine with the amount of lead content exceeding the threshold and from the results of the smear dosage found that normal or normociter cell size can be obtained normal or normochrome (1/3 of the center is pale) whereas abnormalities in the cell form are teardrop cells, ovalocytes, schistocyte, this is due to the effect of lead that disrupts health especially usually occurs in haemotopoetic systems (blood formation system)
A Curious Tale of Economics and Common Carriage (Net Neutrality) at the FCC: A Reply to Faulhaber, Singer, and Urschel
Authors: Winseck Dwayne , Pooley Jefferson
Published: July 2019

This reply to “The Curious Absence of Economic Analysis at the Federal Communications Commission” by Faulhaber, Singer, and Urschel makes three claims. First, we document the paper’s undisclosed origins as a white paper commissioned by an advocacy group with deep ties to the telecommunications industry. Second, we describe two of the authors’ active participation, on behalf of clients, in a range of contested issues before the FCC in recent years. Finally, our review of FCC workshops, roundtables, seminars, dockets, and rulings—including during its landmark 2015 Open Internet Order and several blockbuster mergers and acquisitions—provides detailed evidence to refute the paper’s core “curious absence” charge. The stakes could not be higher, we conclude, as the new FCC chair, Ajit Pai, has repeatedly referenced the paper to justify his rollback of FCC regulations—including, crucially, the common carriage/net neutrality rules so vigorously opposed by the paper’s funders.

Published: July 2019

Research in agricultural biotechnology can produce novel solutions to address the ever growing demand for food, feed, renewable materials and renewable energy using increasingly limited resources. Yet research is expensive with long timelines before implementation can disseminate the benefits to society, so there is a need to maximise co-operation and communication between scientists, stakeholders and their governments, to optimise research, its development and the implementation of research outcomes, into mainstream applications. Recognising the impacts of regulations on biosafety, biosecurity and intellectual property policy on strategies for research, senior and early career researchers from two research intensive universities in Malaysia and Australia, held a workshop to identify and to deliberate over two key areas of technology that offer much promise for agriculture, namely RNA silencing and genome editing. A major focus of the workshop was the regulation of new breeding technologies, and how the regulations need to take into account these new technologies. Themes discussed were the need for harmonisation of international legal frameworks and careful use of terminology, standards and guidelines; and the need for good communication and consensus within and between groups of stakeholders and law-makers. This mini-review highlights the deliberations and recommendations from the workshop.
