Mitigating the Impact on Users’ Privacy Caused by over Specifications in the Design of IoT Applications

Privacy has long been an important issue for IT systems that handle personal information, and is further aggravated as technology for collecting and analyzing massive amounts of data is becoming increasingly effective. There are methods to help practitioners analyze the privacy implications of a system during the design time. However, this is still a difficult task, especially when dealing with Internet of Things scenarios. The problem of privacy can become even more unmanageable with the introduction of overspecifications during the system development life cycle. In this paper, we carried out a controlled experiment with students performing an analysis of privacy implications using two different methods. One method aims at reducing the impact of overspecifications through the application of a goal-oriented analysis. The other method does not involve a goal-oriented analysis and is used as a control. Our initial findings show that conducting a goal-oriented analysis early during design time can have a positive impact over the privacy friendliness of the resulting system.
Wireless Throughput and Energy Efficiency under QoS Constraints

Mobile data tra has experien ed unpre edented growth re ently and is predi ted to grow even further over the oming years. As one of the main driving for es behind this growth, wireless transmission of multimedia ontent has signi antly in reased in volume and is expe ted to be the dominant tra in data ommuni ations. Su h wireless multimedia tra requires ertain quality-of-servi e (QoS) guarantees. With these motivations, in the rst part of the thesis, throughput and energy e ien y in fading hannels are studied in the presen e of randomly arriving data and statisti al queueing onstraints. In parti ular, Markovian arrival models in luding dis rete-time Markov, Markov uid, and Markov-modulated Poisson sour es are onsidered, and maximum average arrival rates in the presen e of statisti al queueing onstraints are hara terized. Furthermore, energy e ien y is analyzed by determining the minimum energy per bit and wideband slope in the low signal-to-noise
The Impact of Time of Day on Energy Expenditure: Implications for Long-Term Energy Balance

There is evidence to indicate that the central biological clock (i.e., our endogenous circadian system) plays a role in physiological processes in the body that impact energy regulation and metabolism. Cross-sectional data suggest that energy consumption later in the day and during the night is associated with weight gain. These findings have led to speculation that when, as well as what, we eat may be important for maintaining energy balance. Emerging literature suggests that prioritising energy intake to earlier during the day may help with body weight maintenance. Evidence from tightly controlled acute experimental studies indicates a disparity in the body’s ability to utilise (expend) energy equally across the day and night. Energy expenditure both at rest (resting metabolic rate) and after eating (thermic effect of food) is typically more efficient earlier during the day. In this review, we discuss the key evidence for a circadian pattern in energy utilisation and balance, which depends on meal timing. Whilst there is limited evidence that simply prioritising energy intake to earlier in the day is an effective strategy for weight loss, we highlight the potential benefits of considering the role of meal timing for improving metabolic health and energy balance. This review demonstrates that to advance our understanding of the contribution of the endogenous circadian system toward energy balance, targeted studies that utilise appropriate methodologies are required that focus on meal timing and frequency.
Cytosolic GABA inhibits anion transport by wheat ALMT1.

Anion transport by Aluminium-activated malate transporter (ALMT) proteins is negatively regulated by gamma-aminobutyric acid (GABA), which increases in concentration during stress. Here, the interaction between GABA and wheat (Triticum aestivum, Ta) TaALMT1 heterologously-expressed in Xenopus laevis oocytes was investigated. GABA inhibited anion transport by TaALMT1 in membrane patches from the cytosolic, not extracellular membrane face, via a reduction in open probability (NPopen ), not an inhibition of channel current magnitude. TaALMT1 currents in patches frequently exhibited rundown with complete removal of cytosolic factors, but were partially sustained by protein kinase C dependent phosphorylation. When applied to whole oocytes a GABA-analogue-BODIPY conjugate inhibited TaALMT1 anion currents from the cytoplasmic face only, whereas free GABA inhibited from both the inside and outside consistent with GABA traversing the TaALMT1 pore then acting from the inside. We propose GABA does not competitively inhibit ALMT conductance through the same pore but rather leads to an allosteric effect, reducing anion channel opening frequency. Across plants GABA is a conserved regulator of anion transport via ALMTs - a family with numerous physiological roles beyond Al3+ tolerance. Our data suggests that a GABA-ALMT interaction from the cytosolic face has the potential to form part of a novel plant signalling pathway.
Automated Nonintrusive Analysis of Electronic System Level Designs

Due to the ever increasing complexity of hardware systems, designers strive for higher levels of abstractions in the early stages of the design process. Modeling hardware at the electronic system level (ESL) is one way to address this demand, with the C++-based system modeling framework SystemC and its abstract communication library transaction level modeling (TLM) having become de-facto standards for ESL system design. While the C++ compiler is sufficient to compile and simulate a given ESL design, for tasks of design understanding, debugging, or validation (where access to the details of design’s structure and behavior is necessarily required), design needs to be processed by an appropriate tool. This problem is often solved by adding instrumentation code to either the design or the library, usually resulting in incomplete logs, work overhead and/or incompatibilities. This paper introduces an approach that automatically extracts information about both, structure and behavior of SystemC designs and TLM transactions, nonintrusively. The information is retrieved from a given design by running it in debug mode while being connected to a preprogrammed debugger, thus leaving the existing sources and workflows untouched while collecting a vast amount of data without user intervention. Illustrating use cases, value change dump files of the SystemC models’ behavior and unified modeling language activity diagrams of transaction protocols are created automatically from simulation runs.
Mycotoxin Occurrence in Maize Silage—A Neglected Risk for Bovine Gut Health?

Forages are important components of dairy cattle rations but might harbor a plethora of mycotoxins. Ruminants are considered to be less susceptible to the adverse health effects of mycotoxins, mainly because the ruminal microflora degrades certain mycotoxins. Yet, impairment of the ruminal degradation capacity or high ruminal stability of toxins can entail that the intestinal epithelium is exposed to significant mycotoxin amounts. The aims of our study were to assess (i) the mycotoxin occurrence in maize silage and (ii) the cytotoxicity of relevant mycotoxins on bovine intestinal cells. In total, 158 maize silage samples were collected from European dairy cattle farms. LC-MS/MS-based analysis of 61 mycotoxins revealed the presence of emerging mycotoxins (e.g., emodin, culmorin, enniatin B1, enniatin B, and beauvericin) in more than 70% of samples. Among the regulated mycotoxins, deoxynivalenol and zearalenone were most frequently detected (67.7%). Overall, 87% of maize silages contained more than five mycotoxins. Using an in vitro model with calf small intestinal epithelial cells B, the cytotoxicity of deoxynivalenol, nivalenol, fumonisin B1 and enniatin B was evaluated (0–200 µM). Absolute IC50 values varied in dependence of employed assay and were 1.2–3.6 µM, 0.8–1.0 µM, 8.6–18.3 µM, and 4.0–6.7 µM for deoxynivalenol, nivalenol, fumonisin B1, and enniatin B, respectively. Results highlight the potential relevance of mycotoxins for bovine gut health, a previously neglected target in ruminants.
Upgrading and Visbreaking of Shengli Ultra-Heavy Oil by Aqua-Thermolysis with Catalyst

The preparation of an organic acid Mo salt was presented in brief and the Mo salt was used as catalyst in aquathermolysis of a Shengli's ultra-heavy crude oil(UHCO) from well Zheng-6-H-2 in purpose of viscosity reduction.Following optimal reaction conditions were established through orthogonally designed single factor experiments:reaction temperature 200℃;reaction time 24 hrs;oil to water ratio 7:3 with formation water from the same well used;catalyst dosage 0.2% of the mass of UHCO;pH=12.For the UHCO having undergone the catalytic aquathermolysis under the optimal reaction conditions,the viscosity at 50℃ was decreased from 524.5 Pa·s to 14.95 Pa·s,or a percent viscosity reduction of 97.15% was observed.The viscosity reduction changed very slightly at the salinity(NaCl concentration) of the water introduced varying in range 7—15 g/L or at the reaction temperature varying in range 200—320℃. In the catalytically aquathermolyzed UHCO the resin and asphaltene fractions were lessened and the saturated and aromatic hydrocarbon fractions were multipled;the elements N,C,and S were lessened and H and O were multipled with H to C ratio increased.The IR-spectrometric analysis showed some reactions occured in the catalytic aquathermolysis:hydrodesulfurization of resin;dealkylation of resin/asphaltene branches;formation and decomposition of mercaptols produced from S-containing compounds in asphaltene through hydrogenation;series reactions of alcoholic compounds in resin.
Structural Evolution of AlN Nanoclusters and the Elemental Chemisorption Characteristics: Atomistic Insight

A theoretical insight into the structural evolution of AlN atomic clusters and the chemisorption of several common alloying elements on a large cluster has been performed in the framework of state-of-the-art density functional theory calculations. We report the findings that the longitudinal growth takes precedence during the early stage of structural evolution of small AlN clusters, when the longitudinal dimension becomes stable, the AlN cluster proceeds with cross-growth and blossoms into the large-size Al60N60. Upon the growth of clusters, the structures tend to become well-knit gradually. As for the evolution of electronic structures of AlN clusters through the HSE06 calculations, the density of states curves become more and more nondiscrete with the atomic structures evolving from small to large size and tend to resemble that of the Wurtzite AlN. The chemisorption characteristics of the large Al60N60 cluster towards different elements such as Al, N, Fe and Cu are also theoretically unveiled, in which it is interestingly found that the N and Cu atoms are likely to be adsorbed similarly at the growth edge position of the Al60N60 cluster and the density of states curves of these two chemisorption systems near the Fermi level also show some interesting similarities.
Electrospun 5-chloro-8-hydroxyquinoline-Loaded Cellulose Acetate/Polyethylene Glycol Antifungal Membranes Against Esca

Esca is one of the earliest described diseases in grapevines and causes trunk damage and the sudden wilting of the entire plant; it is caused mainly by the species Phaeomoniella chlamydospora (P. chlamydospora) and Phaeoacremonium aleophilum (P. aleophilum). In practice, there are no known curative approaches for fighting esca directly, which is a huge problem for preserving vineyards. Micro- and nanofibrous membranes from cellulose acetate (CA) and cellulose acetate/polyethylene glycol (CA/PEG) containing 5-chloro-8-hydroxyquinolinol (5-Cl8Q) were successfully prepared by electrospinning. The surface morphologies and optical and mechanical properties of the membranes were characterized by using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ultraviolet-visible spectroscopy (UV-Vis), water contact angle measurements and mechanical tests. It was found that the bioactive compound release was facilitated by PEG. The antifungal activities of the obtained materials against P. chlamydospora and P. aleophilum were studied. We have demonstrated that 5-Cl8Q is an efficient and sustainable antifungal agent against P. chlamydospora and P. aleophilum. Moreover, for the first time, the present study reveals the possibility of using electrospun polymer membranes containing 5-Cl8Q which impede the penetration and growth of P. chlamydospora and P. aleophilum. Thus, the obtained fibrous materials can be suitable candidates for plant protection against diverse fungi.
Phylogenetic Analysis to Explore the Association Between Anti-NMDA Receptor Encephalitis and Tumors Based on microRNA Biomarkers

MicroRNA (miRNA) is a small non-coding RNA that functions in the epigenetics control of gene expression, which can be used as a useful biomarker for diseases. Anti-NMDA receptor (anti-NMDAR) encephalitis is an acute autoimmune disorder. Some patients have been found to have tumors, specifically teratomas. This disease occurs more often in females than in males. Most of them have a significant recovery after tumor resection, which shows that the tumor may induce anti-NMDAR encephalitis. In this study, I review microRNA (miRNA) biomarkers that are associated with anti-NMDAR encephalitis and related tumors, respectively. To the best of my knowledge, there has not been any research in the literature investigating the relationship between anti-NMDAR encephalitis and tumors through their miRNA biomarkers. I adopt a phylogenetic analysis to plot the phylogenetic trees of their miRNA biomarkers. From the analyzed results, it may be concluded that (i) there is a relationship between these tumors and anti-NMDAR encephalitis, and (ii) this disease occurs more often in females than in males. This sheds light on this issue through miRNA intervention.
Predictor Factors of Perceived Health in Family Caregivers of People Diagnosed with Mild or Moderate Alzheimer’s Disease

Caring for a person diagnosed with Alzheimer’s disease has a negative impact on family caregivers’ psychological health. This study examined the factors related to ‘perceived health’ and ‘presence of new-onset mental health problems’ in family caregivers of people diagnosed with mild and moderate Alzheimer’s disease. A cross-sectional observational study carried out in Almeria’s Healthcare District (Spain). A total of 255 family caregivers (42.4% cared for people with mild Alzheimer’s disease and 57.6% cared for people with moderate Alzheimer’s disease) participated in the study from January to December 2015. Mainly, caregivers were women (81.5% in the mild Alzheimer’s disease group and 88.4% in the moderate Alzheimer’s disease group), and their average age was 56.54 years (standard deviation (SD) = 13.13) and 54.47 years (SD = 11.71), respectively. Around 47% of the caregivers had been caring for the person with Alzheimer’s between two and five years. The Goldberg General Health Questionnaire was used to measure perceived health and the presence of new-onset mental health problems. An exploratory descriptive analysis and a multivariate logistic regression analysis were conducted. For caregivers of people with mild Alzheimer’s disease, ‘perceived health’ was related to ‘perceived social support’ (r = −0.21; p = 0.028), ‘person’s level of dependency’ (r = −0.24, p = 0.05), ‘severity of the person’s neuropsychiatric symptoms’ (r = 0.22; p = 0.05), and ‘caregiver’s emotional distress in response to the person’s neuropsychiatric symptoms’ (r = 0.22; p = 0.05). For caregivers of people with moderate Alzheimer’s disease, ‘perceived health’ was related to ‘perceived social support’ (r = −0.31; p ˂ 0.01), ‘presence of neuropsychiatric symptoms’ (r = 0.27, p = 0.01), ‘severity of the person’s neuropsychiatric symptoms’ (r = 0.32, p = 0.01) and ‘caregiver’s emotional distress in response to the person’s neuropsychiatric symptoms’ (r = 0.029; p = 0.01). The presence of new-onset mental health problems was detected in 46.3% (n = 50) of caregivers of people with mild Alzheimer’s and 61.9% (n = 91) of caregivers of people with moderate Alzheimer’s. When people are diagnosed with mild Alzheimer’s disease, intervention programs for caregivers should aim to regulate emotions and promote positive coping strategies. When people are diagnosed with moderate Alzheimer’s disease, intervention programs for caregivers must allow them to adapt to caregiving demands that arise with the progression of Alzheimer’s disease.
Effects of physical exercises on semen quality and reproductive outcomes in male infertility

Abstract Background: Infertility has troubled the world's 186 million people, and male infertility accounts for more than half. The literature of physical exercise related to semen quality has shown inconsistent results, and there is currently no systematic review to evaluate the effects of exercise on reproductive outcomes in male infertility patients. This study aims to assessing the effects of exercise interventions based on randomized controlled trials (RCTs) on semen quality and reproductive outcomes in male infertility. Methods: English and Chinese literature about physical exercise treatment for male infertility published before July 31, 2019 will be systematic searched in PubMed, Embase, Web of Science, Cochrane Library, Open Grey, Clinicaltrials.gov, Chinese Clinical Trial Registry, WANFANG, VIP Chinese Science and Technology Journal Database, CNKI, Chinese biomedical document service system (SinoMed). Only RCTs of patients with male infertility will be included. Literature screening, data extraction, and the assessment of risk of bias will be independently conducted by 2 reviewers, and the 3rd reviewer will be consulted if any different opinions existed. Live-birth rate, pregnancy rate, adverse events (including miscarriage), sperm concentration, progressive motility, sperm morphology, and sperm DNA fragmentation will be evaluated. Systematic review and meta-analysis will be produced by RevMan 5.3 and Stata 14.0. This protocol reported in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) statement, and we will report the systematic review by following the PRISMA statement. Conclusion and dissemination: We will assess the efficacy and safety of physical exercise on semen quality and reproductive outcomes in infertile men. The findings will be published in a peer-reviewed journal to provide evidence-based medical evidence for clinical decision making and the patient's lifestyle guidance.

Challenges to achieving appropriate and equitable access to Caesarean section: ethnographic insights from rural Pakistan

Abstract Access to Caesarean section (C-section) remains inadequate for some groups of women while others have worryingly high rates. Understanding differential receipt demands exploration of the socio-cultural, and political economic, characteristics of the health systems that produce them. This extensive institutional ethnography investigated under- and over-receipt of C-section in two rural districts in Pakistan – Jhelum and Layyah. Data were collected between November and July 2013 using semi-structured interviews from a randomly selected sample of 11 physicians, 38 community midwives, 18 Lady Health Visitors and nurses and 15 Traditional Birth Attendants. In addition, 78 mothers, 35 husbands and 23 older women were interviewed. The understandings of birth by C-section held by women and their family members were heavily shaped by gendered constructions of womanhood, patient–provider power differentials and financial constraints. They considered C-section an expensive and risky procedure, which often lacked medical justification, and was instead driven by profit motive. Physicians saw C-section as symbolizing obstetric skill and status and a source of legitimate income. Physician views and practices were also shaped by the wider health care system characterized by private practice, competition between providers and a lack of regulation and supervision. These multi-layered factors have resulted in both unnecessary intervention, and missed opportunities for appropriate C-sections. The data indicate a need for synergistic action at patient, provider and system levels. Recommendations include: improving physician communication with patients and family so that the need for C-section is better understood as a life-saving procedure, challenging negative attitudes and promoting informed decision-making by mothers and their families, holding physicians accountable for their practice and introducing price caps and regulations to limit financial incentives associated with C-sections. The current push for privatization of health care in low-income countries also needs scrutiny given its potential to encourage unnecessary intervention.
Prediabetes and Risk for Cardiovascular Disease by Hypertension Status in Black Adults: The Jackson Heart Study

OBJECTIVE Recent studies have suggested that prediabetes is associated with an increased risk for cardiovascular disease (CVD) only among individuals with concomitant hypertension. RESEARCH DESIGN AND METHODS We analyzed the association between prediabetes and CVD by hypertension status among 3,313 black adults in the Jackson Heart Study (JHS) without diabetes or a history of CVD at baseline (2000–2004). Prediabetes was defined as fasting plasma glucose between 100 and 125 mg/dL or hemoglobin A1c between 5.7 and 6.4% (39 and 46 mmol/mol). Hypertension was defined as systolic/diastolic blood pressure ≥140/90 mmHg and/or self-reported antihypertensive medication use. Participants were followed for incident CVD events and all-cause mortality through 31 December 2014. RESULTS Overall, 35% of JHS participants did not have prediabetes or hypertension, 18% had prediabetes alone, 22% had hypertension alone, and 25% had both prediabetes and hypertension. Compared with participants without either condition, the multivariable-adjusted hazard ratios for CVD events among participants with prediabetes alone, hypertension alone, and both prediabetes and hypertension were 0.86 (95% CI 0.51, 1.45), 2.09 (1.39, 3.14), and 1.93 (1.28, 2.90), respectively. Among participants with and without hypertension, there was no association between prediabetes and an increased risk for CVD (0.78 [0.46, 1.34] and 0.94 [0.70, 1.26], respectively). No association was present between prediabetes and all-cause mortality among participants with or without hypertension. CONCLUSIONS Regardless of hypertension status, prediabetes was not associated with an increased risk for CVD or all-cause mortality in this cohort of black adults.
