Implementation and Analysis of Key Reinstallation Attack

-The objective of the paper is to implement and analyzed the impact of Key Reinstallation Attack (popularly dubbed as KRACK) on debian based machines. The paper elucidates on the capture of packets through the attack without being a part of the network and affecting the target machines with the help of an attack machine placed inside the network. It basically exploits the nonce of the network which ultimately paves way to the execution of the attack. The issue tends to gather more eyeballs as it affects all devices using Wi-Fi through WPA2 protocol. Hence, the catastrophe complimented along the attack is severe. The analysis of the impact is carried on by analyzing the type of packets visible as well as captured during the course of the implementation. Here, we have created a python script which identifies whether the targeted machine is vulnerable to KRACK or not and corresponding to that the packet capture starts and ultimately, the impact is measured.
Interpersonal Chemistry: What Is It, How Does It Emerge, and How Does It Operate?

Although chemistry is a well-known, sought-after interpersonal phenomenon, it has remained relatively unexplored in the psychological literature. The purpose of this article is to begin articulating a theoretically grounded and precise definition of interpersonal chemistry. To that end, we propose a conceptual model of interpersonal chemistry centered around the notion that when two or more individuals experience chemistry with one another, they experience their interaction as something more than the sum of their separate contributions. Our model stipulates that chemistry encompasses both behavior (i.e., what chemistry “looks like”) and its perception (i.e., what it “feels like”). The behavior involves interaction sequences in which synchronicity is high and in which people’s goals are expressed and responded to in supportive and encouraging ways. The perception of chemistry includes cognitive (i.e., perception of shared identity), affective (i.e., positive affect and attraction), and behavioral (i.e., perceived goal-relevant coordination) components. We review existing research on chemistry as well as supporting evidence from relevant topics (e.g., attraction, similarity, perceived partner responsiveness, synchrony) that inform and support this model. We hope that this conceptual model stimulates research to identify the circumstances in which chemistry arises and the processes by which it affects individuals, their interactions, and their relationships.
Financial Literacy of SME Managers in Developing Economy: A Case of Tanzania

Developing economies particularly in Africa suffer from many financial system impediments. The general issue has a permeable impact on the way SMEs managers act on the role of firm financial management, therefore having well placed financial literacy level becomes an issue at stake. In this study of financial literacy for SMEs managers based in Tanzania, we use descriptive statistics, ANOVA and logistic regression to analyze the level of financial knowledge and behavior in different constructs. We discover the medium level of financial literacy and the differences between the levels of financial literacy of various groups shows the importance of financial education provision and enablement of access to financial education and financial products for firm managers. The study calls for integrated efforts by the government, regional and multilateral organizations, funders and individuals to curb the situation.
Persistent Streptococcus pyogenes infection of the forearm following blunt trauma

Abstract Necrotizing soft tissue infections are aggressive manifestations of Streptococcus pyogenes, often described after minor skin trauma. However, a subset of infections may present without cutaneous findings. We report a case of toxic shock syndrome and recalcitrant streptococcal infection of the forearm in a healthy teenager following blunt trauma.
Alteration in Gene Pair Correlations in Tryptophan Metabolism as a Hallmark in Cancer Diagnosis

Tryptophan metabolism plays essential roles in both immunomodulation and cancer development. Indoleamine 2,3-dioxygenase, a rate-limiting enzyme in the metabolic pathway, is overexpressed in different types of cancer. To get a better understanding of the involvement of tryptophan metabolism in cancer development, we evaluated the expression and pairwise correlation of 62 genes in the metabolic pathway across 12 types of cancer. Only gene AOX1, encoding aldehyde oxidase 1, was ubiquitously downregulated, Furthermore, we observed that the 62 genes were widely and strongly correlated in normal controls, however, the gene pair correlations were significantly lost in tumor patients for all 12 types of cancer. This implicated that gene pair correlation coefficients of the tryptophan metabolic pathway could be applied as a prognostic and/or diagnostic biomarker for cancer.
Effect of Alkaline and Acidic Wash Treatments on Functional Properties and Color of Monterey Sardine (Sardinops sagax caerulea)Minced Flesh

Abstract Modification of pH during washing showed a beneficial effect on the composition, color and gel-forming ability of Monterey sardine minced flesh. Further improvements in colorand gel-forming ability were achieved by washing under acidic conditions. The proposed washing procedures reduced water usage from 10 to 55% as compared to those used for the washing of dark fleshed fish. Final recoveries after washing were 52% and 49.5% for solids, and 57.4% and 55.8% for protein for acidic and alkaline processes, respectively. Gel-forming ability of mince was compromised as a result of pH modifications. Further studies are required to improve the gel-forming ability of mince by adjusting pH above 6.7 during sol/gel preparation.
Characteristics of the human endometrial regeneration cells as a potential source for future stem cell-based therapies: A lab resources study

Abstract Background Human endometrium with consecutive regeneration capability undergoes monthly hormonal changes for probable implantation, which confirms the presence of the cells in the basalis layer known as stem cell. Objective Previously, we reported the isolation and culture of the mesenchymal-like cells from human endometrium. In this study, we evaluated the biological and stemness characteristics of these cells. Materials and Methods The characterization of Yazd human endometrial-derived mesenchymal stem/stromal cells (YhEnMSCs) was assessed using immunofluorescence (IF) staining for CD105, VIMENTIN, and FIBRONECTIN as markers and RT-PCR for CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, MHCI, CD14, and MHCII genes. Flow cytometry (FACS) was performed for CD44, CD73, CD90, and CD105 markers. Moreover, the differentiation capacity of the YhEnMSCs to the osteoblast and adipocytes was confirmed by Alizarin Red and Oil Red staining. Results YhEnMSCs expressed CD105, VIMENTIN, FIBRONECTIN, CD44, CD73, and CD90 markers and CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, and MHCI, but, did not express CD14, MHCII. Conclusion Our data confirm previous reports by other groups indicating the application of endometrial cells as an available source of MSCs with self-renewal and differentiation capacity. Accordingly, YhEnMSCs can be used as a suitable source for cell-based therapies.
Use of Locally Enhanced Sampling in Free Energy Calculations: Testing and Application to the α → β Anomerization of Glucose

We present a new approach to calculating conformational equilibria in complex molecules, multiple-copy locally enhanced sampling (LES), and apply this approach to the well-known α → β anomeric equilibrium in glucose. Although a variant of this method has been previously applied to protein stability mutations, it is particularly suited to analyze conformational equilibria in molecules such as glucose, with its many OH groups. This methodology allows us to more rapidly calculate complex equilibria both in vacuo and in solution. We have employed a “generic” force field using 1,1-dimethoxymethane and 1,1-dihydroxymethane as models to derive the torsional parameters associated with O−C−O−C and O−C−O−H fragments. Within this model, we can definitively establish the magnitude of intramolecular and solvation contributions to the α → β equilibrium. Specifically, we find that in vacuo glucose prefers to be in the α configuration by ∼0.5−1.0 kcal/mol (predominantly because of the gauche tendency of the O−C−O−C linka.
Antidepressant adherence and its predictors in immigrants with depression

Abstract Immigrants in Korea are relatively vulnerable in terms of medication self-management and have low levels of medication adherence. We aimed to evaluate antidepressant adherence and its patterns in immigrants and to identify predictors of nonadherence. In this matched cohort study using the National Health Insurance claims database, immigrants who were newly prescribed antidepressants were identified (n = 2,398). The immigrants were matched with native-born Koreans in a 1:1 ratio. Antidepressant adherence was measured by the medication possession ratio at monthly intervals. Logistic regression was performed to compare antidepressant nonadherence between immigrants and native-born Koreans, and to identify factors affecting immigrants’ nonadherence. The average medication possession ratio of immigrants was 27.1%, which was lower than that of native-born Koreans (30.9%) (P = .038). Immigrants had a lower likelihood of adherence than native-born Koreans (odds ratio [OR] 0.76, 95% confidence interval [CI] 0.3–0.92). Older age, visiting a psychiatrist for the first diagnosis of depression (OR 2.24, 95% CI 1.60–3.13), achieving appropriateness of care (OR 3.54, 95% CI 2.51–4.98), and having a usual source of care (OR 1.69, 95% CI 1.25–2.27) were associated with a higher likelihood of adherence in immigrants. This study showed that antidepressant adherence of immigrants was lower than that of native-born Koreans. However, it appears that visiting a psychiatrist, achieving appropriateness of care, and having a usual source of care might increase antidepressant adherence among immigrants. Further research that focuses on cultural and/or linguistic factors affecting immigrants’ adherence and healthcare utilization is suggested as a way to increase adherence.
Chemical-extraction methods to estimate bioavailability of DDT, DDE, and DDD in soil

A study was conducted to find a method to determine the bioavailability to earthworms of DDT, DDE, and DDD in soils. Measurements were made of the uptake by Eisenia foetida of the three compounds in seven soils in which they were freshly added or had persisted in the field for up to 49 yr. The worms assimilated 3.15−66.2% of the compounds in the test samples. Different amounts of the three compounds were sorbed by C18 membrane disks placed in suspensions of these soils, and different amounts also were extracted by solutions of tetrahydrofuran in water. The amounts of the compounds taken up by the C18 membrane disks and extracted by the tetrahydrofuran−water mixture correlated well with uptake by E. foetida from 10 samples of these soils. The correlation coefficients (r) were 0.921 or higher for the C18 membrane disk assay and 0.831−0.948 for the tetrahydrofuran-extraction assay in correlations of the chemical and biological assays. These methods thus offer promise as chemical assays to predict bioavailabi.
Three-dimensional structure of human β-defensin 28 via homology modelling and molecular dynamics

The 3D structure of the human β-defensin 28 (HBD-28) has been investigated via homology modelling and molecular dynamics (MD) approach. With known high-resolution structures of HBD-2 and -3, single- and multiple-template sequence alignments are applied to find highly probable candidates for HBD-28, which are in turn refined through MD simulations in pure water and 50% trifluoroethanol/water mixture. The models obtained from homology modelling were assessed by protein structure validation software suite, which includes Procheck, MolProbity, Verify-3D and various structure validation tools. We found that modelling quality is proportionally related to the sequence alignment accuracy. In comparison with circular dichroism experimental data as well as stabilities of β-sheets and α-helix, HBD-28 with a reliable 3D structure was found.
Mitochondria-Targeted Antioxidants: A Step towards Disease Treatment

Mitochondria are the main organelles that produce adenosine 5′-triphosphate (ATP) and reactive oxygen species (ROS) in eukaryotic cells and meanwhile susceptible to oxidative damage. The irreversible oxidative damage in mitochondria has been implicated in various human diseases. Increasing evidence indicates the therapeutic potential of mitochondria-targeted antioxidants (MTAs) for oxidative damage-associated diseases. In this article, we introduce the advantageous properties of MTAs compared with the conventional (nontargeted) ones, review different mitochondria-targeted delivery systems and antioxidants, and summarize their experimental results for various disease treatments in different animal models and clinical trials. The combined evidence demonstrates that mitochondrial redox homeostasis is a potential target for disease treatment. Meanwhile, the limitations and prospects for exploiting MTAs are discussed, which might pave ways for further trial design and drug development.
Geographical distribution and antibiotics susceptibility patterns of toxigenic Vibrio cholerae isolates from Kisumu County, Kenya

Background Multiple drug resistance has become a major threat to the treatment of cholera. Recent studies in Kenya have described the epidemiology, especially the risk factors, of cholera; however, there is little information on the phenotypic and drug susceptibility patterns of Vibrio cholerae (V. cholerae) in outbreaks that in the recent past have occurred in western Kenya. Aim To characterise and determine the antibiotics’ susceptibility profiling of toxigenic V. cholerae isolates from Kisumu County. Setting The project was conducted in Kisumu County, Kenya. Methods A total of 119 V. cholerae O1, biotype El Tor, isolates collected during 2017 cholera outbreak in Kisumu County were used for this study. The samples were cultured on thiosulphate-citrate-bile salts sucrose (TCBS) agar and biochemical tests were carried out using standard procedures. Susceptibility tests were conducted by using various conventional antibiotics against standard procedures. Results Of the 119 isolates, 101 were confirmed to be V. cholerae belonging to serotypes Inaba and Ogawa, with Inaba being the predominant serotype (73.95%). The isolates were susceptible to ciprofloxacin (100%), ofloxacin (100%), gentamycin (100%), doxycycline (99%), ceftriaxone (99%) and streptomycin (96.04%) antimicrobials, and resistant to erythromycin (53.47%), amoxicillin (64.4%), nalidixic acid (83.2%) and ampicillin (89.11%), with high resistance to cotrimoxazole (99%) and tetracycline (97%). Conclusion Vibrio cholerae was resistant to multiple antibiotics, including those commonly used in the management of cholera. Taken together, there is a need to carry out regular surveillance on antimicrobial drug resistance during outbreaks.
Effect of acupuncture treatment on post-stroke cognitive impairment

Abstract Introduction: Post-stroke cognitive impairment (PSCI), which has a high morbidity, is closely associated with the recurrence and rehabilitation of ischemic stroke. There are 2 different stages of PSCI, including post-stroke cognitive impairment with no dementia (PSCIND) and post-stroke dementia (PSD). The latter has a significantly higher mortality rate than the previous one. Therefore, preventing the onset of PSD is of vital importance. However, there is no unequivocally effective prevention or treatment for PSCI, except intensive secondary prevention of stroke. The primary aim of this protocol is to explore whether acupuncture can improve cognitive function of patients with PSCIND and reduce the chances of developing PSD. On this bias, we also want to explore its possible mechanisms. Methods and analysis: A prospective, multicenter, large sample, randomized controlled trial will be conducted. A total of 360 eligible patients will be recruited from 5 different hospitals and randomly allocated into the acupuncture group (AG), sham acupuncture group (NAG), and waiting-list group (WLG) in a 1:1:1 ratio. The intervention period of NAG and AG will last 3 months (30 minutes per day, 3 times per week). Primary and secondary outcomes will be measured at baseline, 12 weeks (at the end of the intervention), 24 weeks (after the 12-week follow-up period), and 36 weeks (after the 24-week follow-up period). Resting-state and task-state functional MRI will be conducted at baseline and 12 weeks. Ethics and dissemination: The ethic committee of First Teaching Hospital of University of Traditional Chinese Medicine approved the study. Study results will be first informed to each participant and later disseminated to researchers, and the general public through courses, presentations and the internet, regardless of the magnitude or direction of effect. The results will also be documented in a published peer-reviewed academic journal. Registration: We have registered at ClinicalTrials.gov(ChiCTR2000033801).
Thermal explosion in a droplet-gas cloud

The effect of the presence of a spray of liquid fuel on thermal explosion in a combustible droplet-gas cloud is investigated. By ‘thermal explosion’ we refer exclusively to the initial stages of the behaviour of the combustible medium as its temperature begins to rise and various competing physical and chemical processes are called into play. A qualitative analysis of the system of governing equations is carried out using an advanced geometrical asymptotic technique (the integral manifold method). Possible types of dynamical behaviour of the system are classified and parametric regions of their existence are determined analytically. It is demonstrated that the original problem can be decomposed into two subproblems, due to the underlying hierarchical time scale structure. The first subproblem relates to the droplet heat up period, for which a relatively rapid time scale is applicable. The second subproblem begins at the saturation point. For the latter, more significant second stage, it is found that there are five main dynamical regimes: slow regimes, conventional fast explosive regimes, thermal explosion with freeze delay and two different types of thermal explosion with delay (the concentration of the combustible gas decreases or increases). Upper and lower bounds for the delay time are derived analytically and compared with results of numerical simulations, with rather satisfactory agreement.
EEVA (Electronic Eigenvalue): A New QSAR/QSPR Descriptor for Electronic Substituent Effects Based on Molecular Orbital Energies

Abstract A new descriptor of molecular structure for use in the derivation of predictive QSAR and QSPR models. EEVA, is described. EEVA (Electronic Eigen Value) is a modification of the recently proposed EVA approach, but it is based on computationally derived molecular orbital energies instead of vibrational frequencies. Like EVA, it is also invariant to alignment of the structures concerned. EEVAs performance has been tested in different applications and its predictive ability was clearly demonstrated. In particular, it seems to be suitable for ‘pure’ electronic substituent effects i.e., for cases in which both hydrophobic and steric factors are of minor importance.
X-ray diffraction studies of expanded fluid mercury using synchrotron radiation

Energy-dispersive x-ray diffraction measurements using synchrotron radiation at SPring-8 for expanded fluid Hg were carried out over the wide density range from the liquid to the dense-vapour region including the metal-non-metal (M-NM) transition region. The density ranges from 13.6 to . We developed a high-pressure vessel and a sapphire cell for the x-ray diffraction measurements under high temperature and pressure up to and 1765 bar. We obtained the structure factor S(k) and the pair distribution functions g(r). The density variations of the interatomic distance and coordination number obtained were discussed in relation to the M-NM transition in fluid Hg. It was found that the volume expansion of liquid Hg in the metallic region is not accompanied by a uniform increase of , but is mainly caused by a decrease of . When the transition region is crossed, the rate of decrease of becomes small and starts to elongate. We discussed some previous band calculations for expanded fluid Hg and concluded that it is essential for explaining the M-NM transition in liquid Hg to take the fluctuation of into account. When the density decreases down to the dense-vapour region, the first maxima of g(r) are located at around 3.3-3.4 A, which is close to the interatomic distance of Hg dimers.
BOND RESONANCE ENERGY AND VERIFICATION OF THE ISOLATED PENTAGON RULE

The isolated pentagon rule (IPR) states that fullerenes with isolated pentagons are kinetically much more stable than their fused pentagon counterparts. This rule can be verified in terms of a graph-theoretically defined bond resonance energy. In general, a {pi} bond shared by two pentagons has a large negative bond resonance energy, thus contributing significantly to the increase in kinetic instability or chemical reactivity of the molecule. The existence of such highly antiaromatic local structures sharply distinguishes IPR-violating fullerenes from isolated-pentagon isomers. {pi}bonds shared by two pentagons are shared by many antiaromatic conjugated circuits but not by relatively small aromatic conjugated circuits. 39 refs., 3 figs., 5 tabs.
A Tale of Two Emotions: The Diverging Salience and Health Consequences of Calmness and Excitement in Old Age

Abstract Using two studies, we examined the late life prevalence and health consequences of discrete positive emotions posited to motivate rest and recovery (calmness) or pursuit of novelty and stimulation (excitement). Study 1 assessed the salience of these discrete emotions in older adults (n=73, Mage=73) relative to younger adults (n=73, Mage=23) over a one-week period. Multilevel models showed that older (vs. younger) adults reported higher calmness and lower excitement. Study 2 examined the longitudinal health consequences of calmness and excitement in old age (n=336, Mage=75), as moderated by perceived control. Multilevel growth models showed that calmness, but not excitement, buffered against 10-year declines in psychological well-being (perceived stress, depressive symptoms) and physical health (physical symptoms, chronic conditions) for older adults with low perceived control. Results suggest that positive emotions with disparate motivational functions become more (calmness) or less (excitement) salient and have diverging implications for health in old age.
