Searching for spatial variations of α 2 /μ in the Milky Way

Aims. We probe the dependence of α 2 /μ on the ambient matter density by means of spectral observations in submm- and mm-wave bands. Methods. A procedure is suggested for exploring the value of F = α 2 /μ , where μ = m e / m p is the electron-to-proton mass ratio, and α = e 2 / ( (cid:2) c ) is the ﬁne-structure constant. The fundamental physical constants, which are measured in di ﬀ erent physical environments of high (terrestrial) and low (interstellar) densities of baryonic matter are supposed to vary in chameleon-like scalar ﬁeld models, which predict that both masses and coupling constant may depend on the local matter density. The parameter Δ F / F = ( F obs − F lab ) / F lab can be estimated from the radial velocity o ﬀ set, Δ V = V rot − V fs , between the low-laying rotational transitions in carbon monoxide 13 CO and the ﬁne-structure transitions in atomic carbon [C i ]. A model-dependent constraint on Δ α/α can be obtained from Δ F / F using Δ μ/μ independently measured from the ammonia method. Results. Currently available radio astronomical datasets provide an upper limit on | Δ V | < 110 m s − 1 (1 σ ). When interpreted in terms of the spatial variation of F , this gives | Δ F / F | < 3 . 7 × 10 − 7 . An order of magnitude improvement in this limit will allow us to independently test a non-zero value of Δ μ/μ = (2 . 2 ± 0 . 4 stat ± 0 . 3 sys ) × 10 − 8 , recently found with the ammonia method. Considering that the ammonia method restricts the spatial variation of μ at the level of | Δ μ/μ | ≤ 3 × 10 − 8 and assuming that Δ F / F is the same in the entire interstellar medium, one obtains that the spatial variation of α does not exceed the value | Δ α/α | < 2 × 10 − 7 . Since extragalactic gas clouds have similar densities to those in the interstellar medium, the bound on Δ α/α is also expected to be less than 2 × 10 − 7 at high redshift if no signiﬁcant temporal dependence of α is present.
Direct Solar Viewing Calibration Concept for Future CERES-, GERB-, or Libera-Type Earth Orbital Climate Missions

: Better predictions of global warming can be enabled by tuning legacy and current computer simulations to Earth radiation budget (ERB) measurements. Since the 1970s, such orbital results exist, and the next-generation instruments such as one called “ Libera ” are in production. Climate communities have requested that new ERB observing system missions like these have calibration accuracy obtaining signi ﬁ cantly improved calibration SI traceability and stability. This is to prevent untracked instrument calibration drifts that could lead to false conclusions on climate change. Based on expe- rience from previous ERB missions, the alternative concept presented here utilizes directly viewing solar calibration, for cloud-size Earth measurement resolution at , 1% accuracy. However, it neglects complex already used calibration technol-ogy like solar diffusers and onboard lights, allowing new lower cost/risk unconsidered spectral characterizing concepts to be introduced for today ’ s technology. Also in contrast to near future ERB concepts already being produced, this enables in- ﬂ ight wavelength dependent calibration of Earth-observing telescopes using direct solar views, through narrowband ﬁ lters continuously characterized on-orbit.
Prognostic Significance of Progenitor Cell Markers CD34/CD38 Expression in Acute Myeloid Leukemia (AML) Egyptian Patients

Introduction: The relapse of Acute Myeloid Leukemia (AML) is thought to reflect the failure of current therapies to target leukemia stem cells, typically enriched in the CD34/CD38 cell population. The aim of this study was to determine the prognostic significance of progenitor cell markers CD34/CD38 in AML. Methods: Progenitor cell markers CD34/CD38 expression was determined on bone marrow mononuclear cells of 84 newly diagnosed adult AML patients with 18 age and sex matched controls, using CD38FITC/CD34PE panel of monoclonal antibodies and analyzed by Flowcytometry technique. Results: Expression of CD34 and CD38 cell markers was detected in 79.8% and 85.7% of AML patients respectively, and there was a highly significant difference of CD 34 expression among cases and controls (p≤0.001). No significant correlation was found between both markers and any of the hematological findings, cytogenetic and FLT3 mutation except with peripheral blood blasts (p=0.05 and 0.005, respectively) and FAB subtypes for CD34 (p=0.006). A significant correlation was found between various CD34/CD38 groups and total leucocytic count, hemoglobin, peripheral blood blasts, and FAB subtypes (p=0.05, 0.047, 0.035 and 0.002 respectively). Also, there was no significant association between both markers expressed separately or in combination with response rate, overall survival and progression free survival. Conclusion: Both progenitor cell markers CD34/CD38 expression might be used as susceptible markers providing important clues for future studies in the early detection of resistant AML cases.

Improved Phonotactic Language Recognition Using Collaborated Language Model

In this paper an approach to build a collaborated feature supervector is proposed and a collaborated language model (CLM) builded with binary decision tree feature surpervector and N-gram feature supervector is introduced and applied to deal with the problems of language identification tasks such as handling long term contexts and too many parameters. Experiments are carried out on the database of National Institute of Standards and Technology language recognition evaluation 2009 (NIST LRE 2009). The experimental results have confirmed that phonotactic language recognition system using the collaborated language model yields 1.07%, 2.68%, 13.48% in equal error rate (EER), which means 8.54%, 12.70% and 4.60% relative reduction for 30s, 10s, 3s compared to the baseline system, respectively.
Energy optimization for Cellular-Connected UAV Mobile Edge Computing Systems

Driven by the increasing demand of compute-intensive mobile applications and the battery-constrained of unmanned aerial vehicles (UAVs). This paper investigates the cellular-connected UAV mobile edge computing systems where the UAV is served by terrestrial base station (TBS) for computation offloading. For tackling the large number of bits of UAV, we propose a resource partitioning strategy where one portion of tasks is migrated to TBS for computing and the other portion of tasks is locally computed at UAV. Our goal is to minimize the UAV energy consumption by jointly optimizing resource partitioning, UAV trajectory and bit allocation under the constraints of UAV mobility and TBS energy budget. The formulated problem is shown to be a non-convex optimization problem, which is hard to tackle. To this end, we derive a sub-optimal solution by leveraging successive convex approximation (SCA) technique. The numerical results show that there exists a tradeoff between propulsion energy consumption of UAV and computation energy consumption of UAV. In addition, it also shows that our proposed scheme saves a large amount of energy compared with the benchmark scheme.
Running head: TEACHING READING THROUGH COMICS The Implementation of Comic Books in a Foreign Language Environment Focusing on the Reading Skill in Primary School Students

This classroom project evidences the results of the implementation of four main reading strategies: glossary, bilingual dictionary, transparent words, and key words to evidence the effect in the reading comprehension of 28 fifth-grade students in a public school in Pereira. The preservice teachers guided students in the acquisition and use of these reading strategies during 10 English lessons through different reading comprehension activities in order to collect and analyze students’ responses and students’ linguistic outcomes via instruments such as students’ artifacts, observations, and journals. The teachers designed the lessons and then they reflected on them. The results obtained from this implementation indicated that the strategies taught affected in a positive way students’ performance in the reading comprehension activities as they were able to summarize the story and create their own comic using a basic plot structure. This all together impacted the students’ reading comprehension strategies development and their rhetorical awareness. TEACHING READING THROUGH COMICS ii Resumen A través de este proyecto se evidencian los resultados de la implementación de cuatro estrategias de lectura: glosario, diccionario bilingüe, cognados, y palabras claves. Esto con el propósito de demostrar su efectividad en el desarrollo de la comprensión lectora de 28 estudiantes de grado quinto en un colegio público en Pereira. Las practicantes guiaron a los estudiantes en la desarrollo y uso de las estrategias de lectura mencionadas con anterioridad durante 10 clases de inglés, por medio de diferentes actividades que tenían como objetivo la comprensión lectora, y éstas a su vez fueron recolectadas para analizar a fondo la producción de los estudiantes. Partiendo del portafolio creado por cada estudiante, los practicantes fueron capaces de diseñar las clases acorde a la capacidad de los estudiantes, y reflexionar a partir de lo que funcionó o no dentro del salón de clases. Los resultados obtenidos en la implementación de este proyecto indicaron que las estrategias usadas por las practicantes tuvieron un impacto positivo en el desempeño de los estudiantes en las actividades de comprensión lectora, y en el momento de crear su propio cómic haciendo uso de una estructura narrativa. Finalmente, el resultado de ambas actividades tuvo un efecto positivo en el proceso de desarrollo de la habilidad lectora y conciencia retórica de los estudiantes. TEACHING READING THROUGH COMICS iii
Organizational Meeting Orientation: Setting the Stage for Team Success or Failure Over Time

Teams are an integral tool for collaboration and they are often embedded in a larger organization that has its own mission, values, and orientations. Specifically, organizations can be oriented toward a variety of values: learning, customer service, and even meetings. This paper explores a new and novel construct, organizational meeting orientation (the set of policies and procedures that promote or lead to meetings), and its relationship to perceived team meeting outcomes and work attitudes. An organization’s policies, procedures, and overall orientation toward the use of team meetings—along with the quality and perceived effectiveness of those meetings—set the stage for how teams develop and collaborate. Across two exploratory studies, we demonstrate that perceptions of an organization’s orientation toward meetings is associated with the perceived quality and satisfaction of team meetings, along with work engagement and intentions to quit. Employees who feel meetings lack purpose or are overused tend to be less engaged with their work and more likely to consider leaving the organization. Based on the findings, we conclude with a robust discussion of how meeting orientation may set the stage for team interactions, influencing how their team operates over time on a given project or series of projects. An organization’s orientation toward meetings is a new construct that may exert an influence on team dynamics at the organizational level, representing a factor of the organization that affects how and when teams meet and collaborate.
A Closed-Form Approximation of the Gaussian Noise Model in the Presence of Inter-Channel Stimulated Raman Scattering

An accurate, closed-form expression evaluating the nonlinear interference (NLI) power in coherent optical transmission systems in the presence of inter-channel stimulated Raman scattering (ISRS) is derived. The analytical result enables a rapid estimate of the signal-to-noise ratio and avoids the need for integral evaluations and split-step simulations. The formula also provides a new insight into the underlying parameter dependence of ISRS on the NLI. Additionally, it accounts for the dispersion slope and arbitrary launch power distributions including variably loaded fiber spans. The latter enables real-time modeling of optical mesh networks. The results is applicable for lumped amplified, dispersion unmanaged, and ultra-wideband transmission systems. The accuracy of the closed-form expression is compared to numerical integration of the ISRS Gaussian noise model and split-step simulations in a point-to-point transmission, as well as in a mesh optical network scenario.
Exploring Training Effect in 42 Human Subjects Using a Non-invasive Sensorimotor Rhythm Based Online BCI

Electroencephalography based brain-computer interfaces (BCIs) show promise of providing an alternative communication channel between the brain and an external device. It is well acknowledged that BCI control is a skill and could be improved through practice and training. In this study, we explore the change of BCI behavioral performance as well as the electrophysiological properties across three training sessions in a pool of 42 human subjects. Our results show that the group average of BCI accuracy and the information transfer rate improved significantly in the third session compared to the first session; especially the significance reached in a smaller subset of a low BCI performance group (average accuracy <70%) as well. There was a significant difference of event-related desynchronization (ERD) lateralization for BCI control between the left- and right-hand imagination task in the last two sessions, but this significant difference was not revealed in the first training sessions. No significant change of R2 value or event-related desynchronization and synchronization (ERD/ERS) for either channel C3 or channel C4, which were used for online control, was found across the training sessions. The change of ERD lateralization was also not significant across the training sessions. The present results indicate that BCI training could induce a change of behavioral performance and electrophysiological properties quickly, within just a few hours of training, distributed into three sessions. Multiple training sessions might especially be beneficial for the low BCI performers.
Efeito imediato de uma sessão de treinamento do método Pilates sobre o padrão de cocontração dos músculos estabilizadores do tronco em indivíduos com e sem dor lombar crônica inespecífica

RESUMO Este estudo teve por objetivo analisar o efeito imediato de uma sessão de exercícios do método Pilates sobre o padrão de cocontração (agonista/antagonista) dos músculos superficiais (iliocostal lombar e reto abdominal) e profundos (oblíquo interno e multífido) do tronco em indivíduos com e sem dor lombar durante teste de resistência muscular localizada. Participaram do estudo sujeitos adultos, de ambos os sexos, com idade entre 19 e 59 anos, separados em dois grupos: grupo com dor lombar (n=9) e grupo sem dor lombar (n=9). Foram coletados os sinais eletromiográficos dos músculos: oblíquo interno (OI), multífido lombar (MU), iliocostal lombar (IL) e reto abdominal (RA), durante as contrações isométricas voluntárias máximas e o teste de Biering-Sorensen antes e após a realização do protocolo de exercícios do método Pilates. Foi calculada a cocontração entre OI/MU direito e esquerdo (OI/MUd, OI/MUe) e RA/IL direito e esquerdo (RA/ILd e RA/ILe). A cocontração entre OI/MUd, OI/MUe, RA/ILd e RA/ILe foi, respectivamente, 41,4, 32,4, 56 e 31,2% maior no grupo com dor lombar (p<0,001 e p=0,003, p=0,004 e p=0,01). A condição inicial apresentou cocontração antagonista 26,3 e 43,4% maior entre OI/MUd (p=0,023, p=0,03). Uma sessão de treinamento com exercícios do método Pilates foi capaz de reduzir a cocontração entre os músculos do tronco (em indivíduos com e sem dor lombar inespecífica).
Sense-Based Topic Word Embedding Model for Item Recommendation

As a useful way to help users filter information and save time, item recommendation intends to recommend new items to users who tend to be interested. As the most common format related to items in online social networks, short texts have always been disregarded by previous research on item recommendation. The sparse features and insufficient information in short texts render the extraction of features from short texts difficult. To address the problems of short text feature extraction and item recommendation, we introduce a sense-based word embedding method to enrich word features and aid in item topic extraction. The sense is used to demonstrate the semantic meaning of a word since each word contains different senses, and each sense can be used to describe various words. Thus, the sense is befitting to enrich the information of short texts and address the problem of polysemy. By combining topic distribution, social relationships, and users’ interests and interactions, we propose a time-aware probabilistic model to profile a user’s preference score on items. By predicting the user preference score at a future time interval, the items with top scores can be regarded as the recommended items. Different experiments on real-world datasets are deployed to prove the feasibility and efficiency of sense-based short text topic assignment and item recommendation in multiple languages. The prediction results also demonstrate that the model substantially outperforms the compared methods.
Acute effect of salbutamol on the cardiovascular system during exercise in patients with moderate or severe asthma: a randomized, double-blind, and cross-over study

| Salbutamol is a β2-agonist of short duration commonly used in patients with asthma to prevent symptoms during or after exercise. Hemodynamic changes at rest are well described. However, there is little data on the effects on heart rate (HR) and blood pressure (BP) during exercise and recovery phase in patients with moderate or severe asthma A randomized, double-blind, cross-over study was conducted, including 15 individuals with moderate and severe asthma, mean age 46.4±9.3 years. Patients underwent a maximal 2-day exercise test with 400 mcg salbutamol or 4 placebo puffs. Throughout the protocol, HR, BP, perceived exertion and peak of expiratory flow (PEF) were monitored. After the use of salbutamol, the PEF value increased by a mean of 28.0±47.7L/m, remaining increased at 5, 10 and 15 minutes of passive recovery compared to placebo (p<0.05). The HR, BP and effort perception variables were similar across interventions at all stages of the protocol (p>0.05). These results suggest that the use of salbutamol is safe and that HR does not need to be adjusted to prescribe exercise intensity following salbutamol administration in subjects with moderate or severe asthma.
The topologies of separate continuity. I

A function f( , ) of two variables is said to be separately continuous if for each fixed y and each fixed x, the functions f(, y) and f(x,) are continuous functions of one variable. Separately continuous functions seem to be playing a larger rôle in analysis than formerly. In (1) there is an account of the theory of semigroups in which the multiplication is separately continuous, and in (9) various analytic theorems are obtained by the study of separately continuous functions f(s, t), where t ranges over a set T, and s ranges over a set of functions on T.
Symmetry sets

Synopsis For a smooth manifold M ⊆ ℝn, the symmetry set S(M) is defined to be the closure of the set of points u∈ℝn which are centres of spheres tangent to M at two or more distinct points. (The idea has its origin in the theory of shape recognition.) The connexion with singularities is that S(M) can be described alternatively as the levels bifurcation set of the family of distance-squared functions on M. In this paper a multi-germ version of the standard uniqueness result for versal unfoldings of potential functions is used to obtain a complete list of local normal forms (up to diffeomorphism) for the symmetry sets of generic plane curves, generic space curves, and generic surfaces in 3-space. For these cases the authors verify that M can be recovered as the envelope of a family of spheres centred at smooth points of S(M).

even more so. And second, simply finding autocorrelated disturbances for an indicator is not a sufficient basis for eliminating it. While this clearly does affect the stability of the item and scale over time, nothing in the reported analysis has shown that it will affect the relationships of political efficacy with other constructs. It is very possible that the source of autocorrelation in these items is unique or idiosyncratic. On the basis of the analysis presented in this article, therefore, there is no reason to believe that these sources of variation in the indicators that are independent of efficacy will correlate systematically with any other constructs of interest. For those working in this area, then, three alternative suggestions may be offered: (1) discare this scale entirely and look for better indicators of efficacy; (2) increase the reliability of the present scale by developing and testing additional items; or, for those who have no choice but to work with data already collected, (3) continue to use all four items in a summated scale and make the appropriate corrections for unreliability. The worst alternative would be to use only the two items as concluded by the authors.
Vehicular Networks Simulation With Realistic Physics

Evaluation of cooperative automated driving applications requires the capability of simulating the vehicle and traffic dynamics as well as the communications with a level of accuracy that most of the current tools still lack. In this paper, we explore the use of game engines in hybrid traffic-network simulators. We describe and validate a novel framework based on this approach: Veneris. Our framework is made of a traffic simulator, implemented on the top of the Unity game engine, which includes a realistic vehicle model and a set of driving and lane change behaviors adapted to a 3D environment that reproduces real-world traffic dynamics; a ray-launching propagation simulator on graphics-processing-unit (GPU), called Opal, and a set of modules, which enable bidirectional coupling with the OMNET++ network simulator. The more relevant and novel mechanisms of Veneris are introduced, but further implementation details can be checked on the source code provided in our repository. We discuss the validation tests we have performed and show how it provides accurate results in three key areas: 1) the fidelity of the vehicle dynamics; 2) the recreation of realistic traffic flows, and; 3) the accuracy of the propagation simulation. In addition, the general results of the expected performance are provided.
Learning-aided Proactive Block Provisioning in Block-stream as a Service for Lightweight devices

Nowadays, lightweight devices together with mobile devices are widely used in our daily life, especially performing some delay-sensitive and interactive services. Block-stream as a service (BaaS) is a new service delivery model in which services can be separated into independent code blocks. The server only delivers necessary blocks to improve the quality of service. The system needs to learn which blocks are necessary over time. We propose an learning-aided active service provisioning scheme for BaaS. In this scheme, lightweight devices learns to prefetch service blocks ahead of time to reduce delay of downloading. The algorithm optimizes the long-term delay with constraints on the time-average energy consumption. In such a system, there are many random variables which have no prior information. But our proactive block provisioning needs to predict the demand of the block by probabilities. So before the online schedule, a learning process is added to estimate the maximum likelihood estimation(MLE) of the state transition probabilities of the block requesting process. Extensive simulations verify the effectiveness of the proposed scheme.
