The geometry of Banach spaces

An article containing carton, and method of assemblying it, for packaging a lamp and lamp shade in the same carton in a minimum of space and with little chance that the lamp and lamp shade will be damaged during transport. The lamp is attached to a first support panel with heat shrinkable material, and the lamp shade is attached between second and third support panels with heat shrinkable material surrounding the support panels and the shade. The first support panel is operatively fastened to the bottom of the carton, and the assembly of the lamp shade and second and third support panels, wrapped by heat shrinkable material, is positioned within the carton so that the lamp and shade are always maintained in spaced relationship in the carton horizontal dimensions, and so that the lamp does not abut the shade supporting spider. The third panel has a central opening through which a portion of the lamp extends into the interior volume defined by the shade. A detachable harp from the lamp may be disposed between the second support panel and the heat shrinkable material, and impact absorbing pads may be disposed between the supporting spider and the second support panel.
Aalborg Universitet Problem-based learning in a box lessons learned from an educational design experiment Davidsen,

In this study, we present an educational design experiment seeking to promote interaction and knowledge sharing in groups and to establish a sense of community among students during a semester at Aalborg University, Denmark. The experiment is materialised as a tangible artefact in the form of a colourful box with materials and texts. Some of the materials are oriented towards supporting the collaborative activities taking place in the group, while others are intended to support individual groups in displaying a visual identity and the public historical trajectory of their problem-based learning process to other groups or peers. The lessons learned from the experiment highlight that educational designs are difficult to implement in practice if it is not mandatory for the students, teachers and supervisors to take part. Furthermore, we imagined the box as a toolbox to support process-related aspects of problem-based learning, such as collaborative interaction, problem formulation and the collaborative learning process itself, whereas the students requested specific ‘how to’ materials for certain project activities – focusing more on the semester product and the outcome of problem-based learning.
DeepER - Deep Entity Resolution

Entity resolution (ER) is a key data integration problem. Despite the efforts in 70+ years in all aspects of ER, there is still a high demand for democratizing ER - humans are heavily involved in labeling data, performing feature engineering, tuning parameters, and defining blocking functions. With the recent advances in deep learning, in particular distributed representation of words (a.k.a. word embeddings), we present a novel ER system, called DeepER, that achieves good accuracy, high efficiency, as well as ease-of-use (i.e., much less human efforts). For accuracy, we use sophisticated composition methods, namely uni- and bi-directional recurrent neural networks (RNNs) with long short term memory (LSTM) hidden units, to convert each tuple to a distributed representation (i.e., a vector), which can in turn be used to effectively capture similarities between tuples. We consider both the case where pre-trained word embeddings are available as well the case where they are not; we present ways to learn and tune the distributed representations. For efficiency, we propose a locality sensitive hashing (LSH) based blocking approach that uses distributed representations of tuples; it takes all attributes of a tuple into consideration and produces much smaller blocks, compared with traditional methods that consider only a few attributes. For ease-of-use, DeepER requires much less human labeled data and does not need feature engineering, compared with traditional machine learning based approaches which require handcrafted features, and similarity functions along with their associated thresholds. We evaluate our algorithms on multiple datasets (including benchmarks, biomedical data, as well as multi-lingual data) and the extensive experimental results show that DeepER outperforms existing solutions.
Fluctuations in the collected charge in integrating photoconductive detectors under small and large signals: the variance problem

Charge collection efficiency (CE) η 0 under small signal conditions, corresponding to a uniform field in the detector medium, has been widely used in evaluating the performance of photoconductive detectors. The present paper answers the question, ‘What is the variance of the collected charge in an integrating detector as a function of photoinjection level and what are the errors if we continue to use the small signal equations? ’ The variance σ02 in η 0 under small signals has been theoretically derived in the literature and has been a key factor in the detective quantum efficiency modeling of integrating detectors based on various semiconductors. σ02 is a noise source and can degrade the detector performance under incomplete charge collection. The statistical variance σ02 in the CE η 0, under small signals and the variance σr2 in the CE ηr under an arbitrary injection level r (injected charge divided by charge on the electrodes) have been studied using the Monte Carlo simulation model developed in this work to evaluate the difference between σr2 and σ02 from small to large signals. Initial injection of electron and hole pairs and their subsequent transport and trapping in the presence of an electric field, which is calculated from the Poisson equation, is used to calculate the photocurrent. Each injected carrier is tracked as it moves in the semiconductor until it is either trapped or reaches the collection electrode. Trapped carriers do not contribute to the photocurrent but continue to contribute to the field through the Poisson equation. The instantaneous photocurrent i ph(t) is calculated from the drift of the free carriers through the Shockley–Ramo theorem. i ph(t) is integrated over the duration of the photocurrent to calculate the total collected charge and hence the CE ηr . The variance σr2 in ηr is found from multiple simulations of ηr . The ηr and σr2 have been generated over varying charge injection ratios r, the electron and hole ranges μτ, mean photoinjection depths δ and drift mobility ratios b. At full injection, the deviation Δσr2 of the CE variance σr2 from the uniform field case σ02 ( i.e.Δσr2 = σr2−σ02) may be as much as 40% larger or 20% lower than the small signal model prediction. This study provides the extent of errors involved in the variance of the CE in non-uniform fields and quantifies the increase in errors that can occur in high injection cases. In practice, typical injection ratios are less than 0.2, which means that the magnitude of percentage error Δσr2/σ02 is less than 5%.
Formation of accretion disk by hydrodynamic subcritical transition

This work employs input-output analysis that is computationally efficient to provide insight into the dominant length scale the transition mechanism in rotating plane Couette flow that is relevant to the accretion disk. We also incorporate componentwise analysis to isolate the effect of different input body forces and different output velocity responses. We compared results associated with three different Reynolds numbers and rotation numbers considering both the overall effect and the effect under isolated input and output directions. We observe different patterns in which the maximum energy amplification strength changes as Reynolds number and rotation number change. We also derive the scaling law of the largest input-output gain over Reynolds number and rotation number, which suggests a higher rotation rate is playing a stabilizing role. We observe that the maximum amplification at rotation number equal to one shows symmetry against the lift-up mechanism in non-rotating plane Couette flow. As the stabilizing effect of rotation is further increased, we observe the most amplified flow structures are more elongated in the spanwise direction reminiscent of the Taylor-Proudman effect.
Numerical simulation of sound scattering by a convected vortex

The sound scattering by a convected isentropic vortex is numerically studied by solving the linearized Euler equations (LEE) with high-fidelity finite-difference methods and non-reflecting boundary conditions. Our computations are in good agreement with previous studies. Simulations for the scattering from a Taylor vortex at a range of convected velocity reveal that the convection of the vortex leads to the spectral broadening of the incident waves. The power spectral density analyses of the scattered pressure in the frequency domain show that the range of the spectral broadening is strongly influenced by convected velocity. This fact can be explained by the relative motion between the vortex and observer associated with the Doppler factor. The sidebands originating from the scattered fields at a fixed point in the frequency domain can be associated with the scattered beams observed in the case of scattering by a steady vortex.
Low Cost Hand Held Device For Leakage Detection From Microwave Oven

Microwave heating systems for industrial uses, notably for food and farm goods have been extensively developed. Microwave energy is now being used in many ways, with greater focus on consumption. If utilized for a consumer product as a power source, microwaves are typically employed in a totally shielded enclosure that does not allow access while the microwave source is running. The radio frequency (RF) leakage above 5mW (+ 10 dBm) is dangerous to humans, according to the World Health Organization (WHO) guideline. This manuscript focuses on the low cost hand held device for detection of microwave energy radiation because it is very hazardous for human body. This kind of device will be very helpful for clean and green society.
Thyroid Hormone Receptor b Inhibits Self-Renewal Capacity of Breast Cancer Stem Cells

Background: A subpopulation of cancer stem cells (CSCs) with capacity for self-renewal is believed to drive initiation, progression, and relapse of breast tumors. Methods: Since the thyroid hormone receptor b (TRb) appears to suppress breast tumor growth and metastasis, we have analyzed the possibility that TRb could affect the CSC population using MCF-7 cells grown under adherent conditions or as mammospheres, as well as inoculation into immunodeficient mice. Results: Treatment of TRb-expressing MCF-7 cells (MCF7-TRb cells) with the thyroid hormone triiodothyronine (T3) decreased significantly CD44/CD24 and ALDH cell subpopulations, the efficiency of mammosphere formation, the self-renewal capacity of CSCs in limiting dilution assays, the expression of the pluripotency factors in the mammospheres, and tumor initiating capacity in immunodeficient mice, indicating that the hormone reduces the CSC population present within the bulk MCF7-TRb cultures. T3 also decreased migration and invasion, a hallmark of CSCs. Transcriptome analysis showed downregulation of the estrogen receptor alpha (ERa) and ER-responsive genes by T3. Furthermore, among the T3-repressed genes, there was an enrichment in genes containing binding sites for transcription factors that are key determinants of luminaltype breast cancers and are required for ER binding to chromatin. Conclusion: We demonstrate a novel role of TRb in the biology of CSCs that may be related to its action as a tumor suppressor in breast cancer.
Metal–organic frameworks for chemical conversion of carbon dioxide

Role of MOFs in CO2 chemical conversion; Photocatalytic and electrocatalytic CO2 reduction; Role of linkers and metals in CO2 chemical conversion; and MOF composites and films in CO2 conversion. In this review, we analyze the emerging field of metal–organic frameworks (MOFs) as catalysts for chemical conversion of CO2, with examples ranging from heterogeneous CO2 organic transformation to heterogeneous CO2 hydrogenation, from photocatalytic to electrocatalytic CO2 reduction. We also discuss the role of MOF composites and films in CO2 transformation. Our goal is to have an instrument useful to identify the best MOFs for CO2 conversion.
The relationship between levels of personal economic returns and education indicators 1

This research aimed to examine the relationship between the educational indicators and the level of personal economic returns for Niger, Turkey, and France. In this study, a systematic review design, in which we compared three countries' data and examined the relationship between education indicators and personal economic returns level. There was a very strong correlation between literacy population, mean years of schooling, and educational expenditure, and a modest relationship between population growth rate and the level of personal economic returns, according to the findings of the study. The first predictor was the mean years of schooling and the second predictor was the educational expenditure. The relationship between them and the level of personal economic returns was positive and significant.
Effects of Teachers’ Lecturing Style, Students’ Seating Position and Students’ Seating Preference on Recall

In response to the decline of students’ academic performance in non-western climes, this study investigated the effects of teachers’ lecturing style (interactive and non-interactive lecturing style), students’ seating position (front seat, middle seat and back seat) and students’ seating preference (front seat, middle seat and back seat) on recall, using Secondary School students of a College in Ibadan. The study adopted a 2 x 3 x 3 Factorial between subjects design. Data was collected from one hundred and eight participants (108) who were selected randomly for the study and randomly assigned to groups. The result shows a significant difference in recall for lecturing style at F (1, 90) = 14.127; P < . 01, (interactive lecturing style having a mean of 9.65 and the non-interactive lecturing style with a mean of 7.96). This shows that the interactive lecturing style has a more positive effect on recall. Students’ seating position and seating preference shows no significant difference in recall at F (2, 90) = 1.981; P >. 05 and F (2, 90) = 0.000; P > . 05 respectively. It was also found that there was no significant interaction effect of the three variables on recall at F (4, 90) = 1.138; P > . 05. This study therefore recommends that teachers and instructors should employ an interactive lecturing style to help students have better recall and therefore perform better academically. Also further research should be carried out with a more representative sample in non-western climes.
Studies on the Maternal Inheritance of Plastid Characters in Hosta japonica ASt 1 ERS . et GRAM . f . all omarginata MAK

CORRENS was the first to find a case of maternal inheritance in plants, in a strain of Mirabilis Jalapa, and explained it as a plasmatic and not a nuclear inheritance. BAUR (1911), who observed a similar phenomenon in Antirrhinum majus albomaculatum, proposed a working hypothesis that the character is localized in cytoplasm, and not in plastids. GREGORY (1915), describing the case of maternal inheritance in yellow and variegated plants of Primula sinensis, however, did not support BAUR's hypothesis, and in view of the fact of the presence of normal and yellow chloroplasts side by side in one and the same cell in very young leaves of the plant, assumed that the abnormality is local ized in the chloroplasts. But he could not find this simultaneous presence of different kinds of chloroplasts in mature plants. WINCE (1919), on his paper on non-Mendelian inheritance supported GREGORY'S view. RANDOLPH (1922) studied the development of plastids in the cell of striped maize, which inherited the characters maternally, and observed the cells which contain plastids varying greatly both in size and intensity of green pigment, in the border line between the green and yellow tissues. There are a few other observations on the presence of two kinds of plastids in one and the same cell, but no clear relation of plastids and maternal inheritance was determined. CHITTENDEN (1925), reviewing on 'vegetative segregations,' is inclined to the hypo thesis of plastids inheritance.
Metabolic dysfunction and adipose tissue macrophages : is theremore to glean from studying the lean ?

72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 M etabolic syndrome is a serious health condition that affects approximately 34% of adults. Hallmarks of this syndrome include abdominal obesity, elevated triglyceride levels, reduced HDL cholesterol, hypertension, hyperglycemia, and insulin resistance, and those affected are at heightened risk for the development of type II diabetes, cardiovascular disease, and stroke. Over the past 20 years, an increasing role for low grade, sterile inflammation in insulin resistance and metabolic syndrome has been appreciated. Studies have shown that obesity induces an inflammatory state, which is clinically manifested as increased or altered concentrations of acute-phase response proteins (eg, C-reactive protein), proinflammatory cytokines (eg, interleukin [IL]-6 and tumor ne-
Evaluation of postural instability and impact forces during ingress and egress of scissor lifts at elevations

Workers are at risk when entering or exiting elevated scissor lifts. In this study, we recorded ground shear forces and postural instability from 22 construction workers while they performed ingress and egress between a scissor lift and an adjacent work surface with varying lift gate opening designs, horizontal and vertical gaps, and sloped work surfaces. From the results of this study, we observed higher peak ground shear forces when using a bar-and-chain opening, with larger horizontal gap, with the lift surface more than 8 inches below the work surface, and having a sloped (26 degrees) work surface. Similar trends were observed for postural instability except the influence of vertical distance was not significant. To reduce slip/trip/fall risk and postural instability of workers while entering or exiting an elevated scissor lift, we suggest scissor lifts be equipped with a gate-type opening to replace the bar-and-chain design. We also suggest the lift surface be placed no more than 0.2 m lower than the work surface and the horizontal gap is as small as possible. Selecting a non-sloped surface to exit or enter a scissor lift is also desirable.
Inhibition and decay of motor and nonmotor priming

Motor responses can be facilitated by congruent visual stimuli and prolonged by incongruent visual stimuli that are made invisible by masking (direct motor priming). Recent studies on direct motor priming showed a reversal of these priming effects when a three-stimulus paradigm was used in which a prime was followed by a mask and a target stimulus was presented after a delay. A similar three-stimulus paradigm on nonmotor priming, however, showed no reversal of priming effects when the mask was used as a cue for processing of the following target stimulus (cue priming). Experiment 1 showed that the time interval between mask and target is crucial for the reversal of priming. Therefore, the time in- terval between mask and target was varied in three experiments to see whether cue priming is also subject to inhibition at a certain time interval. Cues indicated (1) the stimulus modality of the target stim- ulus, (2) the task to be performed on a multidimensional auditory stimulus, or (3) part of the motor response. Whereas direct motor priming showed the reversal of priming about 100 msec after mask pre- sentation, cue priming effects simply decayed during the 300 msec after mask presentation. These findings provide boundary conditions for accounts of inverse priming effects.

[3-Lactam Resistance Mechanisms of Methicillin-Resistant Staphylococcus aureus

In vitro and in vivo activity of amoxicillin and penicillin G alone or combined with a penicillinase inhibitor (clavulanate) were tested against five isogenic pairs of methicillin-resistant Staphylococcus aureus (MRSA) producing or not producing penicillinase. Loss of the penicillinase plasmid caused an eight times or greater reduction in the MICs of amoxicillin and penicillin G (from ~64 to 8 J-tg/ml), but not of the penicillinase-resistant drugs methicillin and cloxacillin (~64 J-tg/ml). This difference in antibacterial effectiveness correlated with a more than 10 times greater penicillin-binding protein 2a affinity of amoxicillin and penicillin G than of methicillin and a ~90% successful amoxicillin treatment of experimental endocarditis due to penicillinasenegative MRSA compared with cloxacillin, which was totally ineffective (P < .001). Amoxicillin was also effective against penicillinase-producing parent MRSA, provided it was combined with clavulanate. Penicillinase-sensitive [3-lactamantibiotics plus penicillinase inhibitors might offer a rational alternative treatment for MRSA infections.
Observation and interpretation of the 5p54f35d core-excited configuration in triply ionized neodymium Nd 3 + (Nd IV)

Ultraviolet laboratory observation of the emission spectrum of the triply ionized neodymium Nd IV excited in a vacuum spark source was extended to shorter wavelength region down to 350 ˚A . The present analysis, based on the identiﬁcation of 313 spectral lines, led to the determination of 125 previously unknown energy levels, all but two belonging to the core-excited conﬁguration 5p 5 4f 3 5d in the Nd 3+ ion. Theoretical calculations of even parity conﬁgurations were performed by using the parametric Slater-Racah method including conﬁguration interactions. Energy parameter values were ﬁtted by least-squares with a root-mean-square (rms) deviation of 184 cm − 1 for an average energy E av (5p 5 4f 3 5d) = 221 076 cm − 1 . In this work, we quantitatively conﬁrm the eﬀect of reduction of the 5p 6 4f 3 - 5p 6 4f 2 5d transition probabilities by the conﬁguration interaction between 5p 6 4f 2 5d and core-excited 5p 5 4f 3 5d conﬁgurations, which is similar to the one observed in Nd V for the 5p 6 4f 2 - 5p 6 4f5d transitions.
NUCLEI AND NUCLEAR REACTIONS

The coefficients of analytic forms for the deuteron wave function in the configuration representation for Nijmegen potentials have been calculated numerically. The obtained wave functions do not contain redundant nodes. The calculated parameters of a deuteron agree well with experimental and theoretical data. The polarization characteristics T20 and Ayy calculated with the use of the obtained wave functions are comparable with earlier results.
