Originality of the study - The originality of this study is the correlation between MVA, financial measures and use of strategic planning for value management.
Modulation of the Host Response to Tacaribe Arenavirus Infection in AG129 Mice by MY-24

MY-24 is an aristeromycin derivative previously shown to protect AG129 type I and II interferon receptor knockout mice from lethal challenge with Tacaribe virus (TCRV). TCRV is nonpathogenic to humans, but is closely related to the highly pathogenic New World arenaviruses that cause often-fatal viral hemorrhagic fever syndromes. Remarkably, MY-24 prevented mortality without reducing TCRV burden in the circulation or tissues. To investigate the mechanism by which MY-24 protects AG129 mice against TCRV infection, we first characterized the natural history of disease in the model with an emphasis on cytokine responses and vascular integrity to establish the best times to evaluate the effects of MY-24 treatment on host responses believed to contribute to pathogenesis and fatal outcome. We found that viral replication in the blood and in various tissues precedes a hyperproduction of proinflammatory mediators that may lead to the destabilization of the endothelial barrier and increased vascular leakage believed to contribute to terminal shock associated with severe cases of hemorrhagic fever. We also found slightly reduced virus titers in certain tissues from MY-24-treated mice, suggesting that there may be a weak antiviral effect; however, TCRV was not cleared from lung, spleen, brain or kidney in recovering animals out to 40 days post-infection, indicative of the establishment of chronic infection in mice that are able to survive the initial challenge. Neutralizing antibodies do not appear to play a major role in the antiviral effect of MY-24, whereas reductions in several key proinflammatory cytokines in mice treated with MY-24 may serve to reduce vascular leakage caused by TCRV infection.
Raising the Bar: Evaluating Origin-wide Security Manifests

Defending a web application from attackers requires the correct configuration of several web security mechanisms for each and every web page in that web application. This configuration process can be difficult and result in gaps in the defense against web attackers because some web pages may be overlooked. In this work we provide a first evaluation of the standard draft for an origin-wide security configuration mechanism called the "origin manifest". The mechanism raises the security level of an entire web origin at once while still allowing the specification of web security policies at the web page level. We create prototype implementations of the origin manifest mechanism for both the client-side and server-side, and provide security officers with an automated origin manifest learner and generator to aid them with the configuration of their web origins. To resolve potential collisions of policies defined by the web origin with policies defined by web pages we formalize the comparison and combination of web security policies and integrate it into our prototype implementation. We evaluate the feasibility of the origin manifest mechanism with a longitudinal study of popular websites to determine whether origin manifest files are stable enough to not require frequent reconfiguration, and perform performance measurements on the Alexa top 10,000 to determine the network traffic overhead. Our results show that the origin manifest mechanism can effectively raise the security level of a web origin while slightly improving network performance.
Using the location of maximum region 1 current determined by the Active Magnetosphere and Planetary Electrodynamics Response Experiment as a proxy

[1] Using the location of maximum region 1 current determined by the Active Magnetosphere and Planetary Electrodynamics Response Experiment as a proxy for the open/closed field line boundary, we monitor the evolution of the amount of open magnetic flux inside the magnetosphere during 772 substorms. We then divide all substorms into three classes, depending on the amount of open flux at expansion phase onset. Studying the temporal variations during the substorms of each class for a number of related geophysical parameters, we find that substorms occurring while the amount of open flux is large are generally more intense. By intense we mean that the auroral electrojet, region 1 current, auroral brightness, tail dipolarization and flow speed, ground magnetic signatures, Pi2 wave power, as well as the intensity and extent of the substorm current wedge (SCW) are all larger than during substorms that occur on a contracted polar cap. The SCW manifests itself as an intensification of the nightside R1 and R2 current system after onset. Our analysis shows that to dispose of large amounts of accumulated open magnetic flux, large substorms are triggered in the terrestrial magnetosphere.
Optimal measurements to access classical correlations of two-qubit states

We analyze the optimal measurements to access classical correlations in arbitrary two-qubit states. Two-qubit states can be transformed into the canonical forms via local unitary operations. For the canonical forms, we investigate the probability distribution of the optimal measurements. The probability distribution of the optimal measurements is found to be centralized in the vicinity of a specific von Neumann measurement, which we call the maximal-correlation-direction measurement (MCDM). We prove that, for the states with zero discord and maximally mixed marginals, the MCDM is the optimal measurement. Furthermore, we give an upper bound of quantum discord based on the MCDM, and investigate its performance for approximating the quantum discord.
The Use of History of Science as a Cultural Tool to Promote Students' Empathy with the Culture of Science*

It is difficult for students to understand historical settings, connect to today's world, interpret and appreciate scientists' efforts within current perspectives. Empathizing with historical characters and events can mediate understanding nature of physics for students. The purpose of this study was to investigate the effect of history of science on students' empathy with the historical characters and the events. With regards of socio-cultural theory, empathy was defined as a cultural tool, which mediates between students and the science society. The study was conducted in a private high school with participation of twenty-one 9th grade students in physics class for the unit of The Nature of Physics. A qualitative case-study method was employed. Data resources were video and audio recordings, field notes, students' tasks, interviews, and surveys. After transcribing and categorizing, the data were analyzed and patterns were organized. The findings supported eight aspects of empathy: Making Personal Connections, Imagination, Identification, Humanization, Understanding the Events, Understanding Dif- ferent Perspectives, Understanding the Tentativeness of the Conclusions and Taking Perspectives. The results supported that students could interact with the culture of science with the use of the aspects of historical empathy. The use of the aspects of empathy attracted students' interest in physics lesson. The results are also promising for students' understanding nature of science.
Differentially Private Robust Low-Rank Approximation

In this paper, we study the following robust low-rank matrix approximation problem: given a matrix $A \in \R^{n \times d}$, find a rank-$k$ matrix $B$, while satisfying differential privacy, such that $ \norm{ A - B }_p \leq \alpha \mathsf{OPT}_k(A) + \tau,$ where $\norm{ M }_p$ is the entry-wise $\ell_p$-norm and $\mathsf{OPT}_k(A):=\min_{\mathsf{rank}(X) \leq k} \norm{ A - X}_p$. It is well known that low-rank approximation w.r. t. entrywise $\ell_p$-norm, for $p \in [1,2)$, yields robustness to gross outliers in the data. We propose an algorithm that guarantees $\alpha=\widetilde{O}(k^2), \tau=\widetilde{O}(k^2(n+kd)/\varepsilon)$, runs in $\widetilde O((n+d)\poly~k)$ time and uses $O(k(n+d)\log k)$ space. We study extensions to the streaming setting where entries of the matrix arrive in an arbitrary order and output is produced at the very end or continually. We also study the related problem of differentially private robust principal component analysis (PCA), wherein we return a rank-$k$ projection matrix $\Pi$ such that $\norm{ A - A \Pi }_p \leq \alpha \mathsf{OPT}_k(A) + \tau. $
Stability of a noncanonical scalar field model during cosmological date

Using the noncanonical model of scalar field, the cosmological consequences of a pervasive, self-interacting, homogeneous, and rolling scalar field are studied. In this model, the scalar field potential is “nonlinear” and decreases in magnitude with increasing the value of the scalar field. A special solution of the nonlinear field equations of that has time dependency as fixed point is obtained. The fixed point relies on the noncanonical term of action and -parameter; this parameter appeared in energy density of scalar field redshift. By means of such fixed point the different eigenvalues of the equation of motion will be obtained. In different epochs in the evolution of the Universe for different values of and , the potentials as a function of scalar field are attained. The behavior of baryonic perturbations in linear perturbation scenario as a considerable amount of energy density of scalar field at low redshifts prevents the growth of perturbations in the ordinary matter fluid. The energy density in the scalar field is not appreciably perturbed by nonrelativistic gravitational fields, in either the radiation or matter dominant or scalar field dominated epoch.
Perceived changes to quality of life indicators following a physical activity intervention for recovering cancer patients: A qualitative study.

The aim of this study was to examine the perceived changes to the quality of life (QoL) for a group of recovering cancer patients, following 6 months of physical activity. Background Evidence suggests that physical activity can improve the QoL of recovering cancer patients, reducing many of the side-effects of cancer and its related treatments, including depression, anxiety, chronic fatigue and improve physical and psychological health. Method A qualitative study with 14 mixed site cancer patients aged 43-70 (12 women, 2 men). The intervention was in 2 parts the first part was an 8-week physical activity programme, the second part related to a period of non-supervised, physical activity for 4 months (6 months in total). The Programme took place at a university in the South West of England. Semi-structured interviews with patients took place 3 times over 6 months. A grounded theory approach was used to analyse the data. Results We found that prior to the 6-month physical activity intervention many of the patients were anxious about being able to complete the initial 8 week programme. Anxieties related to low self-esteem and the chronic fatigue resulting from their cancer treatment. Consequently several patients expressed concerns about their ability to help themselves self-manage their recovery through physical activity. On completion of the intervention the majority of patients reported improvements in their perceived QoL relating to their ability to self-manage, their self-efficacy, energy levels, along with decreases in chronic fatigue. Conclusion Our study has provided valuable insights into how the perceived QoL of a group of recovering cancer patients can be improved through a combined 6-month period of supervised and independent physical activity. These findings serve as further evidence of the effectiveness of a person centred healthcare approach for recovering cancer patients.
The Abundance of Carbon Dioxide Ice in the Quiescent Intracloud Medium

We present new observations with the Infrared Spectrograph on board the Spitzer Space Telescope of the solid-CO2 absorption feature near 15 μm in the spectra of eight field stars behind the Taurus complex of dark clouds. Solid CO2 is detected in six lines of sight. New results are combined with previous data to investigate the correlation of CO2 column density with those of other major ice constituents (H2O and CO) and with extinction. CO2 is shown to display a "threshold extinction" effect, i.e., a minimum extinction (A0 = 4.3 ± 1.0 mag) required for detection, behavior similar to that previously reported for H2O and CO. We find a particularly tight correlation through the origin between N(CO2) and N(H2O), confirming that these species form in tandem and coexist in the same (polar) ice layer on the grains. The observed composition of the mantles is broadly consistent with the predictions of photochemical models with diffusive surface chemistry proposed by Ruffle & Herbst. Comparison of our results for Taurus with published data for Serpens indicates significant differences in ice composition consistent with enhanced CO2 production in the latter cloud. Our results also place constraints on the distribution of elemental oxygen between ices and other potential reservoirs. Assuming a constant N(H) to extinction ratio, we show that ~65% of the solar O abundance is accounted for by summing the contributions of ices (~26%), refractory dust (~30%) and gas-phase CO (~9%). If the Sun is an appropriate standard for the interstellar medium, the "missing" oxygen may reside in atomic O I gas and/or (undetected) O2 within the ices.
Anti-ulcer Activity of Some Selected Medicinal Plants: A review

A peptic ulcer is an ulcer of one of those areas of the gastrointestinal tract that are usually acidic. Peptic ulcer formation occurred due to the acid of excess, peptic activity in gastric juice as well as a breakdown in mucosal defenses. Some of anti-ulcer medicines such as proton pump inhibitors and H2 receptor antagonists are used for peptic ulcer treatment. However, these drugs have shown disease relapse, side effects, and even drug interactions. Many medicinal plants exhibit anti-ulcer activity and found useful in the treatment of peptic ulcer. The purpose of this review is to know more about the anti-ulcer properties of the medicinal plants. Serjania marginata (HESM) leaves, thymol obtained from Thymus, Origanum and Cuphea aequipetala infusion (CAI) In this review there is information about some kinds of plants which are very useful in treating peptic ulcer disease such as hydroalcoholic extract obtained from S. marginata (HESM) leaves, thymol obtained from Thymus, Origanum and CAI. These plants were studied by their mechanisms underlying to the gastroprotective effect of thymol and HESM. Furthermore, the study reported the potential effect of involvement of some factors of the protective effect of medical extract, such as prostaglandins (PG), nitric oxide (NO), and a hydrogen sulfide (H2S). Side the effect of these factors in gastro protective, and finally the paper clarified some local mechanisms of actions of some compounds that were involved in mucosal defense or injury.
Age and Gender Distribution of Benign Breast Lesions of Women at Port City of Bangladesh

Background: Benign breast diseases are the most common cause of breast problems. The most common symptoms are breast pain, lumpiness or a lump and nipple discharge. Triple assessment that includes clinical examination, imaging like ultrasonography (USG) or mammography and a pathological examination – FNAC or core needle biopsy has a very high accuracy rate in diagnosing, discrete benign breast diseases and this can be used for reassurance.Objective: The purpose of the present study was to determine the frequency of different types of benign neoplasm of breast lump in different age and sex.Methodology: The present study was carried out at the Department of Pathology, Chittagong Medical College, Bangladesh one year period from May 2005 to June 2006.

Most of the patients were in 31 to 50 years (45.8%) age group and female predominance than male. Fibroadenoma accounted for 76.2%. Sclerosing adenosine the second most common benign breast disease in this study accounted for 9.5% of cases.Conclusion: This study showed that among the benign breast diseases in females there were preponderance of fibroadenoma followed by sclerosing adenosineJournal of Science Foundation 2018;16(1):27-31
The Concept of ADHD in Attachment Related Research

Objective: Parallels in findings of attachment and ADHD research suggest a connection between both constructs. However, the few articles dealing with that tie investigate children with all conceivable expressions of ADHD and have not found sufficient evidence regarding the connection between ADHD and attachment. This study sought to collect evidence of a possible connection between the two aspects among children with the predominantly inattentive ADHD type. Method: The sample consisted of 93 children aged 5 9 years, 48 of whom had an ADHD diagnosis of the predominantly inattentive type. Attachment was coded using the German adaptation of the Attachment Story Completion Task, externalizing behavior problems were rated using the Child Behavior Checklist 4 18. ADHD was assessed using both clinical diagnoses as well as the German ADHD Rating scale. Results: Results revealed a large difference in the distribution of attachment classification between children with ADHD and those without ADHD. Regression analysis, however, showed no independent effect on ADHD when externalizing behavior problems were controlled for. Conclusions: Both constructs seem to be connected, however, in the investigation of the influence of attachment on the disorder, ADHD as a global construct is too unspecific. As opposed to previous studies, considering only the inattentive type, the relation might completely be moderated by externalizing behavior problems. Subsequent studies should first focus on specific symptom patterns which at best should be analyzed within longitudinal studies.
Stability of Steel Structures at Elevated Temperatures: A Hybrid Fire Testing Approach | NIST

The response of structural systems to fire loads is typically assessed through performing ‘standard’ tests under constant mechanical boundary conditions. Such tests are usually performed on the individual elements. Full scale tests showed differences in their behavior compared to the behavior of the individual members tested in standard conditions. Full-scale tests of structural systems remain impractical due to physical, economical, and time constraints. The goal remains to have the capability to predict the behavior of a full-scale test though experimentally testing individual structural members. A promising approach to that problem is “Hybrid Fire Testing (HFT)” where a subset of the structural system (Physical Substructure PS), is physically tested, while the remaining structure (Numerical Substructure NS), is simultaneously numerically analyzed. PS represent the parts of the structure with higher behavioral uncertainty, while the NS represent the parts which can be numerically modelled with high confidence. During the test, the mechanical boundary conditions on the PS and NS are continuously updated. Certain challenges are unique to HFT due to the continuous fire exposure which induces continuous thermal expansions. This paper describes a recent virtual HFT study performed on a ten-story multi-span steel frame assembly, with the focus on the structural stability and interface equilibrium and compatibility between the substructures. In the early stage of this work, the HFT study is done in a virtual environment, where the PS is also modeled numerically as a proof of concept. As part of the study, a traveling fire analysis was performed on the building and results highlighted the importance of considering the performance of the structure as a whole assembly, and showed that individual member standard testing could be unsafe. The paper also describes some of the challenges that are unique to the HFT, and ways to overcome them.
Assessment of Food Consumption Pattern, Anthropometric Parameters and Physical Activity Pattern of Non-Insulin Dependent Diabetics

Abstract Fifty non-insulin dependent diabetic subjects, 25 males and 25 females, free from serious complications were selected from posh areas of Ludhiana city. Diabetic and dietary information was collected using a questionnaire. Diabetic information of the subjects related to etiology of disease, family history and prevalence of symptoms was collected. Dietary information of the subjects was collected to know about their food habits and frequency of consumption of different food groups. Activity pattern of the subjects was recorded from their daily routine, and their involvement in other activities like time spent in recreational activities. Type of job, working hours, duration of sleep and any kind of physical exercise was recorded. Various anthropometric parameters viz. height, weight, Body Mass Index (BMI) and Waist Hip Ratio (WHR), were recorded. The most common reason for diabetes among the selected subjects was obesity which lead 22% subjects to be diabetic. Family history of diabetes was found in 38% subjects. The most common symptoms were polyuria (56%), polydypsia (48%), nocturia (44%), delayed healing (44%), polyphagia (40%) and loss of weight (38%). Twenty-eight percent of the males had normal weight and 56% and 16% males were in 1st and 2nd grades of obesity respectively. Sixty-eight percent and 24% of the female subjects were in 1st and 2nd grades of obesity respectively. As reported by the subjects, majority of them (78%) were not doing any kind of physical exercise. In all 76% of the subjects had disturbed sleep of 5-6 hours. It was found that the majority of the subjects 54% were ova/non-vegetarians. Ninety-four percent subjects liked sweet and salty foods. All the subjects took wheat flour thrice a day. Pulses were consumed by 90% subjects once a day. Forty-eight percent subjects used GLV’s twice a week, 84% of the subjects consumed roots and tubers at least once a day. Fifty-two percent of the subjects consumed fruits once daily. All the subjects consumed milk. About 50% of the subjects consumed fried foods daily.
