The energy system is evolving from smart grid to energy Internet. Virtual power plant (VPP), as an important part of the energy Internet, plays an important role in the distributed energy generation and trading. In this article, a blockchain‐based VPP transaction model is established for the future energy Internet driven by real‐time electricity price. Then the smart contracts for distributed energy trading in VPPs using blockchain technology are proposed, and the key technological difficulties are analyzed and the solutions are given. Experiments show that the proposed model can reflect the supply and demand information in real time, so that two‐way selection can be carried out under the condition of information symmetry when distributed energy is connected to the grid. If our method is applied, we can help distributed energy suppliers set electricity prices, reduce the trust cost and improve the energy trading efficiency. Also, we can help the distributed energy voluntarily participate in VPPs and joint maintain the system, then solve the problem of VPP's coordinated control and scheduling of distributed energy resources.

Inactivation of the tumor‐suppressor gene p16 (MTS1/CDKN2/INK4a) has been described in various human malignancies. Although p16 deletion has been found in various ovarian tumor cell lines, p16 inactivation by homozygous deletion or mutation has been reported only sporadically in primary ovarian carcinomas. In a comprehensive study, we analyzed p16 protein expression by immuno‐histochemistry (IHC) on paraffin sections of 94 primary ovarian carcinomas of different histological subtype. Loss of expression was detected in 19 primary tumors (20%), mainly mucinous and endometrioid carcinomas. To reveal the cause of suppressed expression, we performed (i) analysis of homozygous deletions by comparative PCR after micro‐dissection, (ii) mutation analysis by single‐strand conformation polymorphism analysis and subsequent direct sequencing and (iii) methylation‐specific PCR to determine the methylation status of 5′‐CpG islands. Loss of or weak p16 expression was caused by hyper‐methylation (12/19 IHC‐negative cases), somatic mutation (10 tumors) or homozygous deletion (1 case). Aberrant p16 results by one of these methods were detected in 71–79% of endometrioid and mucinous, but in only 10% of serous‐papillary, carcinomas. Our data suggest that p16 inactivation is a typical feature of certain subtypes of ovarian carcinoma. Int. J. Cancer (Pred. Oncol.) 75:61–65, 1998. © 1998 Wiley‐Liss, Inc.


Linux Transparent Huge Pages (THP) are not able to minimize the virtual memory overhead because they are limited to 2MB pages. We introduce Memomania, a flexible memory allocator that is able to transparently back the application with a mixture of 2MB and 1GB pages. We use Memomania to characterize a subset of SPEC CPU2006 benchmarks and find that (1) using 1GB pages provides a notable runtime improvement compared to THP, and that (2) in some cases, allocating more 2MB pages to an application degrades its performance. We suggest that Memomania can be used in (1) placement algorithms, and (2) micro-architectural studies.


Intermodal transportation has known a great development during last decades as consequence to the development of container transportation services but also because of its sustainability advantages. The development of gateways infrastructures (ports, air ports) but also the extension of gateway concept to dry ports leads to the development of hinterland logistics networks that requires efforts and researches to optimize the design and the configuration of both their infrastructures and their services. The design, configuration and the service network design of a system(network) performing hinterland logistics, obeys to the same objectives as for a transportation and /or distribution network but could differ because of either its specific structure, cost function and/or specific constraints related to the actors points of view. To be cost effective and mitigate the negative environmental and human health effects of distribution operations of road mode, hinterland freight logistics systems should be intermodal by integrating more and more rail and land waterway traffic. The planning of these systems at tactical level, deserve more attention because a great deal of cost effectiveness could be reached at this level. The purpose of this paper is to address a modeling framework for service network design for a based dry ports hinterland logistics system. The models are based on a path fixed charged capacitated formulation and give as outcomes shipping frequencies by service class of each path and by the way the required capacity in gateways and the intermodal dry ports.


The continuing trend of miniaturization in electronic equipment includes demands for thinner and smaller semiconductor devices with higher performance. To ensure the reliability of electronic devices and to enable high-throughput packaging processes, the mechanical properties of ultra-thin chips need to be accurately understood. One important consideration is the residual stress generated during wafer thinning due to the shear force between the grinding wheel and polish pad; this stress can degrade the fracture strength of ultra-thin devices. To reduce this residual stress, we developed a flash light irradiation annealing technique, including optimization of the irradiation conditions of flash light energy, pulse number and pulse duration. The distributions of residual stresses within ultra-thin flash memory chips before and after the annealing were measured using Raman spectroscopy, and their fracture strength was measured using a ball-on-ring test. Also, transmission electron microscopy (TEM) analysis and beam transfer function tests were performed to investigate the changes in mechanical properties and changes to the silicon lattice effected by the annealing. The ultra-fast flash light annealing was found to reduce the residual stress of ultra-thin chips by 50%, thereby improving their fracture strength by 20% compared to unannealed chips.

The cardiac renin–angiotensin–aldosterone system (RAAS) is an endocrine cascade, which results in the conversion of the inactive pro-hormone angiotensin I (Ang I) to the active peptide hormone Ang II, and may also function as an autocrine/paracrine system to modulate cardiac function and growth. Renin, the initial enzyme of this cascade, cleaves the amino terminus of the pre-pro-hormone angiotensinogen, thereby releasing the decapeptide pro-hormone Ang I. Angiotensin-converting enzyme (ACE) removes two additional amino acids to yield the active octapeptide hormone Ang II. Ang II, acting through the AT1 receptor, is a potent vasoconstrictor and stimulates cardiac growth. This cardiac growth may be related to myocyte hypertrophy and/or fibroblast proliferation with a concomitant alteration in the extracellular matrix. Ang II, by interaction with the neuroadrenergic and endothelin systems may cause an increase in local noradrenaline and endothelin levels, which in turn may have direct trophic and toxic effects on the cardiac myocyte. In addition, Ang II stimulates aldosterone secretion from the adrenal glands, which may further stimulate cardiac remodelling. The cellular events triggered by increased Ang II formation, while initially compensatory, may lead to eventual loss of cellular function, contractility, and viability. ACE-inhibitors have been shown to improve survival and cardiac function in patients with left heart failure.

In response to RAAS activation there is an increase, at the level of both gene and protein expression, of components which decrease the local concentration of …

The present study was primarily focused to determine the common presentations and manual diagnostic procedures for sacral malalignments. Forty football players (n = 40), from National Football Club (NFC) were selected for the study. Subjects were constrained to males with no history of orthopedic or neurological issues, and also include the subjects only with normal muscle power and Range of movement (ROM) of the back and extremities. The mean age of the studied population was 22.2 ± 3.9 years, height 175.8 ± 6.6 cms, and weight 87.5 ± 7.1 kgs. The important bony landmarks like Sacral Sulci and Base, Infero-Lateral Angles (ILA) of sacrum, position of L5 vertebra and Sacrotuberous ligament were located manually. These landmarks were considered as an extremely basic and vital for the manual assessment of sacral malalignments. In this study, we observed, 50% i.e., majority of the soccer's were suffered with oblique axis malalignments, includes Right On Right - ROR and Left On Left - LOL of sacral dysfunctions. The players suffered with AP and Transverse axis of sacral malalignments were encountered up to 17.5% and soccer's who had the vertical axis malalignments was observed only in 7.5%. However, this method of assessing the sacral malalignments until then not documented. In this sense, the current study was mainly focused on the assessment and documentation of the different common presentations in sacral malalignments, which are most common in soccer players. This simple method of evaluation is the literature state of the art. The present study may provide the useful informations to analyze the common presentations of sacral malalignments in different sports.


The influence of host-emitter interactions on electroluminescent (EL) performances of thermally activated delayed fluorescence (TADF) emitter had not explored in detail. In this study, by doping DMTDAc into host materials with different polarity and energy levels as emitting layer, we demonstrated that the choice of host can be able to greatly impact on the EL performances. Finally, we found the variation of device performances was mainly dominated by energy transfer and charge trapping progresses in emitting layers, and stable blue TADF device with maximum efficiencies and brightness of 23.74 cd/A, 24.05 lm/W, 21.9% and 5695 cd/m2, was obtained.


Quantum error correction is an important ingredient for scalable quantum computing. Stabilizer codes are one of the most promising and straightforward ways to correct quantum errors, since they do not require excessive complexity of physical qubits, are convenient for logical operations, and improve performance with increasing the involved qubits number. Here, we propose a linear scalable code of the permutative stabilizers for small distances on the ring architecture, which takes into account the topological features of the superconducting platform. We present the way to construct the quantum circuit of the code and provide numerical simulation that demonstrate the exponential logical error rate suppression.


This paper presents the numerically simulated specific absorption rate (SAR) within the human head due to cellular telephones. The frequency considered was 825 MHz and the time averaged radiated power of 0.6 W was used. The influence of the geometrical change of nearby feed on SAR for the homogeneous head model was analyzed. The FDTD code was modified for a parallel processing machine and run on 8 CPU.


In this paper we conduct two experiments within an agent-based double auction market. These two experiments allow us to see the effect of learning and smartness on price dynamics and allocative efficiency. Our results are largely consistent with the stylized facts observed in experimental economics with human subjects. From the amelioration of price deviation and allocative efficiency, the effect of learning is vividly seen. However, smartness does not enhance market performance. In fact, the experiment with smarter agents (agents without a quote limit) results in a less stable price dynamics and lower allocative efficiency.


The precise pressure dependence of apparent diffusion and permeation coefficients was measured by using a microcomputer system for collecting and treating permeation data for CO2 in glassy poly(ethylene terephthalate) below 1 atm between 15 and 40°C. The partial immobilization model was used to determine the dual-mode sorption and mobility parameters. The curves calculated with these parameters were in excellent agreement with experimental data. These parameters were also compared with sorption parameters obtained from measurements at 30°C. There was a small difference between the values of the parameters obtained from these permeation data and those from sorption data which we had previously obtained. Relations between this difference and the method of determination of the parameters are discussed.


We used high-speed full-spectrum interrogation of a Fiber Bragg Grating (FBG) sensor to measure dynamic strain in different sensor packages in real-time. In this effort we performed solenoid impact tests on a variety of sensor mounting structures made with FR4, steel, and carbon fiber composite materials. Full spectrum FBG interrogation at 40 kHz repetition rate was the key that allowed us to measure and compare dynamic strain in the structures, with measurement resolution on the sub-millisecond scale. With this interrogation method we were able to measure the full character of the dynamic strain including the strain non-uniformity and distribution manifested in peak-splitting and spectrum broadening. Results showed that the FR4 board with soft epoxy responded with a maximum dynamic strain on the order of 3000 micro-strain. Adding hard materials such as steel and graphite fiber composite reduced the strain about 7 times. However, the FR4 board mounted in a free-floating configuration using hard epoxy reduced the maximum strain to a value below the noise threshold of the full spectrum interrogation configuration. Here we proposed using edge detection method of FBG interrogation due to its increased strain sensitivity which enabled us to further analyze the critical results obtained by full spectrum interrogation. We also proposed using edge detection to measure sensor strain in real time for the purpose of filtering out the strain noise from useful signal. We will use the results and data obtained with both methods to analyze and enhance the performance of our electric field sensors in environments of high static and dynamic strain.


An experiment to assess different levels of IBA (Indole Butyric Acid) and planting time on rooting and growth of Alstonia cuttings was conducted at Ornamental Horticulture Nursery, Department of Horticulture, The University of Agriculture Peshawar, Pakistan. The experiment was carried out using RCBD design with split plot arrangement. There were five levels of IBA 0, 5, 10, 15 and 20% that were prepared by mixing IBA with talc powder. Cuttings were obtained from healthy, vigorous growing trees which were 15-20 cm long and 2-3 nodes. Leaves were removed from the cuttings and were treated with IBA than planted in plastic bags filled with mixture of sand, clay and FYM with the ratio of 1:1:1 on three different planting times 15th March, 30th March and 14th April. IBA level of 10% showed best results regarding leaf area plant -1 (26.032 cm 2 ), sprout length(18.096 cm), stem diameter (14.44 mm), number of roots plant -1 (15.613), root diameter (3.412 mm) while number of  leaves plant -1 (17.27), root length (14.24 cm) and survival percentage (70%) was best recorded when treated with IBA at level of 5%. However, sprouting percentage and days to bud sprouting were not significantly affected by different levels of IBA. It is observed from the study that there was no significant effect of planting time over any parameter however good results were observed in cuttings planted at 14th April regarding leaf area plant -1 , sprout length, stem diameter, number of roots plant -1 , number of leaves plant -1 , root length, root diameter and survival percentage while sprouting percentage and days to bud sprouting were best when planted at 15th March. IBA at 10% level and 14th April as planting time resulted in overall best performance and hence recommended for treating and planting cuttings of Alstonia. Keywords: Alstonia, Growth attribute, Planting times, IBA.


Severe erection deficit may be caused by an organic vascular pathology or be secondary to chronic deforming pathologies of the penis, as occur in the late and irreversible stages of Peyronie's disease. Penile prosthesis implant is currently the ideal treatment in patients who do not respond to common vasoactive drug therapies. The short penis syndrome is one of the possible complications of the three-part penile prosthesis implant and is probably caused by the fibrocicatricial retraction of the tunica albuginea. The authors checked the functionality and aesthetic result of the complementary phalloplasty technique (circular grafting). At an average follow-up of about six months the authors have not found any infective, erosive or mechanical problems, while the aesthetic and functional result is excellent. This method may therefore be reasonably used in most penile grafts.


We recently reported that RAB GTPase 14 (RAB14) knockdown (KD) increased the frequency and total numbers of erythroid cells generated in vitro in response to erythropoietin (EPO) from either the TF1 human leukemia erythropoietic model cell line or from primary human CD34 + hematopoietic stem-progenitor cells (HSPCs). RAB14 overexpression (OE) had the opposite effect. Thus, RAB14 functions as an endogenous inhibitor of human erythropoiesis (Kim et al ., Br. J. Haematol. , 2015). In contrast to the greater cell numbers generated in the presence of EPO, RAB14 KD TF1 cells grown in standard culture media containing granulocyte-macrophage colony-stimulating factor (GM-CSF; as the only cytokine) generated fewer total cells, compared to empty vector-transduced control TF1 cells. Furthermore, RAB14 KD TF1 cells cultured in GM-CSF media generated greater numbers of erythroid (CD34 - /CD71 + /CD235a + ) cells, as compared to control TF1 cells, suggesting that RAB14 KD stimulated erythropoiesis even in the absence of EPO. Cells generated from RAB14 KD TF1 cells had higher GATA1 and lower GATA2 transcription factor expression, as compared to controls, demonstrating the cells had undergone the "GATA1/2 switch," a hallmark of erythropoiesis. Consistent with higher GATA1 levels, RAB14 KD TF1 cells generated cells with higher levels of b- and g-hemoglobins. Similarly, RAB14 KD in primary human CD34 + HSPCs generated greater numbers of erythroid cells, with or without exogenous EPO. RAB14 KD CD34 + HSPCs cultured in GM-CSF media generated fewer monocytic/granulocytic (CD13 + /CD33 + ) cells, as compared to control CD34 + HSPCs. Interestingly, RAB14 OE CD34 + HSPCs cultured in thrombopoietin (TPO)-containing media generated higher numbers of megakaryocytic (CD34 - /CD41a + /CD42b + ) cells, as compared to control CD34 + HSPCs. In summary, (1) RAB14 KD in TF1 cells or primary human CD34 + HSPCs increased erythropoiesis in the presence or absence of EPO, but reduced myeloid cell differentiation, probably via the GATA1/2 switch; and (2) RAB14 OE in CD34 + HSPCs increased megakaryopoiesis in the presence of TPO. Thus, RAB14 normally serves as an endogenous hematopoietic decision-maker, physiologically inhibiting erythropoiesis and stimulating megakaryopoiesis (and possibly, to a lesser extent, mono-granulopoiesis). Disclosures No relevant conflicts of interest to declare.


The immunological examinations of two cases of pemphigus vulgaris and four cases of bullous pemphigoid in the dog are reported. Deposits of immunoglobulin and complement were identified betweeen epithelial cells of the pemphigus cases and at the epithelial/connectivce tissue junction in the pemphigoid dogs. The bullous autoimmune diseases must be considered in the differential diagnosis of mucosal and skin ulceration in the dog.


Clinton, Chelsea. She Persisted Around the World. Illustrated by Alexandra Boiger, Philomel Books, 2018.
Chelsea Clinton and Alexandra Boiger give us a walk through historic and present day women showing us each woman's great submission to the world we live in. Whether it be through overcoming their own disability, overcoming others' views on placement of women, or overcoming another's thoughts on what women are allowed to do, the main focus is on the fact that they persisted. Using these circumstances that could have gobbled them up, they chose to take the road less travelled and fight for what they believed in—these are stories of women who did not give up but persisted through whatever was trying to hold them back. This book gives us short stories about strong women from the past, like Marie Curie, all the way to amazing women that we are lucky enough to have with us today, like Malala Yousafzai and J.K. Rowling. This shows us that we can look to the past for heroes, but sometimes there are heroes who can be found in our own generation. Chelsea Clinton and Alexandra Boiger did a beautiful job displaying beautiful, imagination igniting pictures and thought-inducing stories that describe the women, what they persisted through, and what they accomplished. Some women even received the Nobel Peace Prize for their contributions.
The beautiful drawings showcase each woman's struggle to persist through her personal issue. Some are simple drawings and others are intricate interpretations that bring their story to life. The illustrations show people from different areas of the world and it even includes a Canadian connection. As Canadians, we can see our faces in this book as a mirror and can see it does not matter what colour our skin is, what area of the world we come from, or what our family circumstances are, we just need to be true to our beliefs and true to our voice in our world. This book empowers young girls to become powerful women.
As the author, Chelsea Clinton, says eloquently at the end of the book for our girls to "speak up, rise up, dream big. These women did that and more. They persisted and so should you."

This article presents an experimental evaluation on using a rened approach to the Latent Semantic Analysis (LSA) for eciently searching very large image databases. It also describes IPL's participa- tion to the image CLEF ad-hoc textual and visual retrieval as well as modality classication for the Medical Task in 2013. We report on our approaches and methods and present the results of our extensive exper- iments applying early data fusion with LSA on several low-level visual and textual features.


We have investigated the possibility to instigate discharges in tissue and evaluated their potential for medical applications. With appropriate electrode configurations, we were able to generate either corona discharges or spark discharges in the tissue itself by applying nominal rectangular high voltage pulses of 30-ns and 380-ns duration, respectively. The shorter pulses were provided by a Blumlein line pulse generator, and the longer pulses were generated with a Blumlein pulse forming network. Sub-microsecond pulsed electric fields have demonstrated remarkable potential in the treatment of solid tumors1. We assumed that the efficacy of the method can be improved by reactive species that are generated in a corona. Changing the polarity of the voltage-bias applied to the center needle of a coaxial delivery system, we were able to compare treatments with and without discharge. However, our experiments did not show any significant advantage of a corona discharge for our configuration and treatment parameters. With the longer pulse it is possible to generate a spark discharge between the tips of two needle electrodes, which are inserted into the tissue. Depending on tissue type (muscle, liver, fat) and pulse amplitude, several tissue-conditioning pulses had to be applied before breakdown could be achieved. When a spark was initiated, the breakdown voltage was lower than expected for liquids but higher than expected for air (at atmospheric pressure). The visual inspection of the tissue damage showed a highly localized incision, which runs between the tips of the needle electrodes. The preliminary histological analysis suggests that the damage is mostly caused by the Shockwave associated with the spark.


A review is given on a study of the gain versus antenna temperature optimisation of small, low cost, prime focus parabolic antennas. Especially the choice of feed system plays an important role in this optimisation. From this study it is concluded that a log periodic dipole antenna is a favourable option. Details and numerical results from simulations for this option are presented. These details show that with a proper construction the antenna gain can be considerably higher then presented in previous reports. Furthermore it is shown that an optimal G/T ratio of the investigated antenna system for astronomy applications needs a different f/d ratio for the parabolic reflector compared to a system for terrestrial use. The results from this study are directly applicable to the One Hectare Telescope as is proposed by the SETI Institute.


The content of Tannin in Root tuber of the cultivated and wild grown Potentilla anserine L. harvested in spring and autumn were determined by the method of oxidation of K2MnO4. Little difference was shown with the content of Tannin between the cultivated and wild grown species but greater gap appears with the content of Tannin in the root tuber harvested at different seasons. Root tuber harvested in autumn contains higher content of Tannin than those harvested in spring, accordingly, a theoretical foundation for optimum harvest season of root tuber of Potentilla anserine L.


Summary form only given, as follows. A plasma-assisted slow wave oscillator (Pasotron) may be operated without external magnetic field allowing for radial motion of the electrons. This phenomenon has been exploited to achieve an increase in the interaction efficiency from /spl sim/20% to /spl sim/50% by injecting electrons into the weak RF field region near the axis and having them bunched as they move axially and radially toward the surface of the slow wave circuit where RF fields are strong and efficient energy extraction occurs. The absence of a guide field, which gives the electrons the freedom to move not only axially but also transversely under the action of the RF fields, explains the high efficiency. This high efficiency is unattainable in conventional backward wave oscillators driven by linear electron beams in the presence of an externally applied guiding magnetic field. In our paper, recent theoretical and experimental studies of this device with two-dimensional electron motion will be described. Both in-situ diagnostics and theoretical analysis confirmed that RF forces dominate the beam dynamics. The innovation of simultaneously controlling the beam cross-section and optimizing the quality factor enables stable, high efficiency operation. These results greatly improve the prospects for developing advanced, plasma assisted, megawatt-class microwave sources.

Motivated by the revitalized interest in the digital quantum simulation of coupled fermion-boson models from medium- and high-energy physics, we investigate the nonequilibrium dynamics following a Yukawa-interaction quench on IBM Q. Adopting -- due to current quantum-hardware limitations -- a single-site (zero-dimensional) version of the scalar Yukawa-coupling model as our point of departure, we design low-depth quantum circuits that emulate its dynamics with up to three bosons. In particular, using advanced circuit-optimization techniques, in the one-boson case we demonstrate circuit compression, i.e.~design a constant-depth circuit containing only two CNOT gates, regardless of the total simulation time. In the three-boson case -- where such a compression is not possible -- we design a circuit in which one Trotter step entails $8$ CNOTs, this number being far below the maximal CNOT-cost of a generic three-qubit gate. Using an analogy with the travelling salesman problem, we also provide a CNOT-cost estimate for quantum circuits emulating the system dynamics for higher boson-number truncations. Based on the designed circuits, we quantify the system dynamics for the initial vacuum state by evaluating the expected boson number at an arbitrary time after a Yukawa-interaction quench, as well as the survival probability of the initial state (the Loschmidt echo). Finally, we make use of the designed circuits to drive adiabatic transitions and compute the energies of the ground- and first excited state of the model under consideration. We validate our results by performing error mitigation in the form of zero-noise extrapolation, finding an excellent agreement of our obtained results with the exact ones obtained through classical benchmarking.

Demands of CW high-power LINAC require SRF cavities operating at the frontier of high accelerating gradient and low RF power dissipation, i.e. high quality factor (Q0). This requirement poses a challenge for standard surface treatment recipes of SRF cavities. In a recent breakthrough, elliptical SRF cavities doped with Nitrogen have been shown to improve Q0 by a factor of 3, close to the fundamental SRF limit. The fundamental mechanisms at microscopic level and optimum doping recipe, however, have still not fully been understood. Materials other than Nb have also been proposed for SRF cavities to overcome the fundamental limit already reached with Nitrogen doping, e.g. Nb3Sn, MgB2, and Nb-SIS multilayer. At TRIUMF, a unique experimental facility is currently being developed to address these issues. This facility will be able to probe local surface magnetic field in the order of the London Penetration Depth (several tens of nm) via β decay detection of a lowenergy radioactive ion-beam. This allows depth-resolution and layer-by-layer measurement of magnetic field shielding effectiveness of different SRF materials at high-parallel field (up to 200 mT). Design and current development of this facility will be presented here, as well as commissioning and future measurements strategies for new SRF materials. BACKGROUND AND MOTIVATION SRF (Superconducting RF) cavities are the backbone of modern LINACs (Linear Accelerators) due to the low power dissipation and high accelerating gradient. The base performance of SRF cavities can be characterized by theQ0 (Quality Factor) vs Eacc (accelerating gradient) curve. Higher Q0 reduces the cryogenic power consumption while larger Eacc (in the unit of MV/m) reduces the overall length of the LINACs. For CW (continuous wave) LINACs, Q0 plays a more important role while for pulsed high-gradient LINACs, Eacc is more crucial. Pushing the performance of SRF cavities has been made possible through decades of intensive research into the fabrication, assembly, surface processing, and metallurgy for over five decades [1]. Most of SRF cavities have been made with bulk Niobium (Nb). Recently the discoveries of Nitrogen-doping [2] and Nitrogen-infusion [3] of Nb SRF cavities have pushed its performance on both Q0 and Eacc close to its fundamental limit. Understanding the ∗ firstname.lastname@example.com 1 This is true in the case of N-infusion, while N-doped SRF cavities have higher Q0 at lower Eacc . mechanism of this doping effect require microscopic studies of the Niobium composition and superconducting properties (such as critical magnetic field of the Meissner state) at the nanometer scale. Active research in alternative materials such as Nb3Sn and MgB2 has also been pursused since the bulk Nb SRF cavities have almost reached the maximum performance. These alternative materials are based on thinfilms due to the fact that only several nm of the inner RF surface layer determine the performance of the SRF cavities. TRIUMF SRF group conducts both SRF cavities design & fabrication, and fundamental SRF studies. Currently there are two SRF LINACs, ISAC-II and ARIEL e-LINAC (electron LINAC), operating. TRIUMF SRF group also collaborates in the fabrication of both cavities and cryomodules for international projects such as RISP (South Korea) and VECC (India) rare-isotope projects. In the field of fundamental SRF, previous studies of N-doped Nb and novel thin film SRF materials have been done with μ-SR (muon spin resonance) technique [4] to measure the field of first magnetic flux entry. Nb, which is a type-II superconductor, is operated in the Meissner superconducting state in SRF cavities. Local magnetic probe techniques such as μ-SR can measure more accurately the fraction volume inside the superconductor which is not in the Meissner state. Therefore this technique is a powerful method to characterize the critical Meissner field that can be achieved. The higher the critical field of the Meissner state, the higher accelerating gradient that the SRF cavity can achieve. Recently, the TRIUMF SRF group has commissioned a RF induction furnace for doping and heat-treatment studies of both sample and test cavities. Two multi-mode coaxial test resonators (a quarter-wave and a half-wave resonator) have also been fabricated to study the doping and heat-treatment effects at lower frequency (low beta) cavities [5]. The purpose of this proceeding is to describe a new facility, β−SRF for the specific purpose of investigating thin-films and multi-layer SRF materials.


Thermodynamic and kinetic studies of MgO reduction by carbon have been carried out. Experimental results indicate that the reduction by carbon results in a porous layer on the surface of the refractory lining, which would allow easy penetration of the slag. In a study of the dissolution of MgO and carbon bearing MgO refractories in both synthetic and industrial slags, a two phase layer was observed on the refractory surface, which consisted of liquid slag and a large number of MgO globules. The implication of this two phase layer for the reactions between the slag and the refractory in industrial practice is discussed.


A novel PON scheme to adopt bidirectional subcarrier OFDM signals transceivers with continuous phase modulation (CPM) and demodulation is proposed and experimentally validated, and which is suitable to simultaneously offer higher receiver performance and simplify digital signal processing.


This thesis examines the nature and character of incompatibilities in current traffic modelling approaches and provides a list of requirements and criteria for dealing with these limitations. Candidate approaches are examined and critiqued in terms of these criteria, and an alternative approach is proposed. The proposed modelling approach considers the behavior of traffic flows in terms of individual vehicles which have self- assignment capabilities.


Sixty seven years to this month of November 2007, Aristides Sousa Mendes stood condemned to one year's suspension on half pay followed by compulsory retirement from the diplomatic service. I will bring before you the case of this Portuguese diplomat, a Righteous Gentile, whom in the War's darkest hour, faced with a political and social order contradictory to human dignity, submitted to moral obligation. Rather than seeking refuge in the magic of faith, he chose effective action, and used his power to help thousands of people escape the German westward advance, a decision for which he was himself to become an outcast – till his death and beyond, for it took almost 50 years for him to be reinstated. Keywords: Aristides Sousa Mendes. Nazism. War.


The paper narrates the implement principle of network monitoring system and analyzes the problems which network monitoring system is faced with in broadband network. Based the description of the scheme and the performance measurement of optimizing methods in broadband network monitoring, it is proposed that exploring relations between application and structure of data capturing software will improve performance notably in 100M Ethernet.

It is intended to call attention to the existing facilities for adequate health instruction, the need, if any, for more and better facilities and the need for teacher training in this field.


HaNDL syndrome (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) is a rare headache disorder previously known as Migraine with cerebrospinal fluid pleocytosis. The disease is characterized by one or more episodes of headache and transient neurological deficits associated with cerebrospinal fluid lymphocytosis. It is a benign disorder and a stroke mimicker. We describe a case of 50 years old lady presented with acute onset headache, right hemi sensory tingling and bilateral papilloedema. Her blood test, MRI of brain and MRV was normal. CSF study revealed lymphocytic pleocytosis. The patient was discharged with full recovery. HaNDL syndrome is a diagnosis of exclusion. High degree of suspicion and characteristic clinical and laboratory findings are important to recognize.

It was previously known as Migraine with cerebrospinal pleocytosis; pseudo migraine with lymphocytic pleocytosis. It was first described in early 19801. It is a rare disorder with Migraine-like headache episodes (typically one to twelve) accompanied by neurological deficits including Hemiparaesthesia, hemiparesis and/or dysphasia, but positive visual symptoms only uncommonly, lasting several hours. There is lymphocytic pleocytosis. The disorder resolves spontaneously within 3 months2. As an example of a rare disease. We described a case of 50 years old lady presented with acute onset headache, right hemi sensory tingling and bilateral papilloedema. Her blood test, MRI of brain and MRV was normal. CSF study revealed lymphocytic pleocytosis. Case Description: A 50 year old lady admitted in the inpatient of the Neurology Department of Dhaka Medical College on 15.02.20 with the history of severe throbbing head ache for 2 days associated with tingling sensation on the he right side of her body. The headache was global, throbbing in nature, severe in intensity and was unremitting. It was associated with several episodes of vomiting. There was associated hemiparaesthesia on her right side. There was no hemiparesis, confusion, visual disturbances, speech difficulty and gait disturbances. She did not have any fever, cough and respiratory distress. Neurologic examination revealed patient was fully conscious, there was no dysarthria or dysphasia. Cranial nerve examination revealed bilateral papilloedema, otherwise all cranial nerves were normal. Motor and sensory examinations revealed no focal deficit. There was no signs of meningeal irritation. Workup revealed unremarkable routine laboratory blood and urine examination. Initial CT scan of brain followed by MRI of brain with contrast and MRV were normal, except congenital absence of right transverse sinuses. CSF study revealed opening pressure 35 cm of water. Cell count revealed 170 cells per cubic millimeter with predominant lymphocyte (86%) and protein 175 mg/dl. CSF gram stain, AFB stain were normal, it was Negative for HSV serology. Blood for ANA and ENA profile were also normal. The patient was treated with Tab Topiramate 25 mg BD and Cap Nortriptyline 25 mg once daily and Tab Paracetamol as required. The head ache was subsided after 5 days of admission. She was discharged after 10 days. At her discharge CSF examination along with opening pressure was normal. Papilloedema was also subsided. Follow up after 2 month revealed no recurrence of headache with normal disc. Discussion: HaNDL (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) is a diagnosis of exclusion. The index case presented with migraine like headache with a transient neurological feature (hemiparaethesia) persisted for > 4 hours, associated with CSF pleocytosis. Other possible etiologic studies were negative and the CSF pleocytosis improved with the improvement of the headache. So the case meets the diagnostic criteria2 of HaNDL (transient headache and neurological deficits with cerebrospinal fluid lymphocytosis) given by international Headache society. At presentation our provisional diagnosis was intracerabral haemorrhage (ICH) with raised intracranial pressure (ICP) though there was no confusion. The ICSOL with raised ICP, Venous stroke, subarachnoid hemorrhage and Meningitis were also our consideration. CT scan revealed no haemorrhage. MRI with contrast revealed no focal lesion and leptomeningeal enhancement. So we went for CSF study keeping in mind of benign intracranial hypertension (BIH) and viral meningitis though the patient had a focal Hemiparaesthesia. CSF pressure was raised but lymphocytic pleocytosis exclude the diagnosis of BIH. As there was no leptomeningeal enhancement and HSV serology was normal, viral etiology was also excluded. So we made the diagnosis of transient headache and neurological deficits with cerebrospinal fluid lymphocytosis. Its important differential is Mollaret Meningitis where focal sign is absent, Mollaret cells might be found. The headache was subsided after 5 days. At 9th day we again performed the CSF study which was normal. This again goes in favor of our diagnosis, transient headache and neurological deficits with cerebrospinal fluid lymphocytosis. In 1981 first reported cases of Bartleson1 et al., patients of both sexes and 16-50 years of age was described where symptoms persisted for 1-12 weeks. Later Gomez ́ Aranda3 et al reported 50 cases with a wide variety of neurological deficits (such as sensory, motor, and language problems) and patient's experiencing 1-12 episodes. In their case series they found mean duration of headache was 19 hour and mean duration of neurologic deficit was 5 hour. In that cases CSF lymphocytes was found ranged from 10 to 760 per cubic millimeter and CSF protein was increased in 96% of patients. In this case reported in this article a lady of 50 years of age was diagnosed and the patient suffered for 1 episode lasting 5 days with no recurrence up to 2 months of follow-up. In 75% of cases it is found to be monophgic1. The etiology of this rare disorder is uncertain. Some researchers predict viral etiology4, some autoimmune etiology5 and some described it as a complicated migraine6.Kappler et al7. Found asymmetric velocities and pulsatilities in middle cerebral arteries using Transcranial Doppler sonography. Cerebral Angiograms that were performed subsequently were within normal limits. This findings provoked the authors to conclude that HaNDL syndrome could represent episodes of migraine due to the similarities of the vasomotor features. The studies conducted to find the association between HaNDL syndrome and acute ischemic stroke, found that despite the presence of neurologic deficits that were often prolonged, diffusion-weighted (DWI) MRI images were normal in all cases.


This paper is devoted to the characterizations of approximate weakly efficient solutions and opproximate properly efficient solutions of vector optimization problems via linear scalarization in a locally convex Hausdorff topological vector space.Firstly,we discuss some properties of free disposal sets.Then,we present necessary and sufficient conditions such that the approximate weakly efficient solution set and approximate properly efficient solution set of vector optimization problem can be expressed as the union of the approximate solution sets of the corresponding linear scalarization problem,respectively.Also,we give an example to illustrate that this equivalent characteriztion does not hold for approximate efficient solution set of vector optimization problem.Our results generalize and unify some previously corresponding linear scalarization works.

In the process the advantages and misunderstanding points have been analyzed. It also clarifies that the insufficiency of the information research and the weak ability of how to act in emergency are the essential reasons which affect the speed of information research. And the author proposes that the role conversion and altruism thinking are the principles that should be followed in the job of information consulting in university libraries.


Disabled elderly people have to rely on wheelchair life. And the wheelchairs are used in daily life with different illumination conditions. This paper proposes a hand gesture recognition method to control wheelchairs based on dynamic colour clustering. As dynamic clustering skin detection algorithm is used, the gesture recognition accuracy is improved. Using skin detection, arm removal and polygon fitting methods, the gesture images collected by a Kinect V2, are recognized as control commands to drive the wheelchair. Experiments show that the proposed method can be applied to different illumination conditions with better recognition accuracy.


Density fluctuations based on lSFW 3 plasma measurements in the range 10 minutes to 1 hour have been investigated in the following solar wind flows at 1 AU: coronal hole, interstream, plasma sheet, coronal mass ejection, and interaction region. The, ISEIl 3 results reinforce the interpretation of large-scale variations in density fluctuations observed by Doppler scintillation measurements inside 0.2 AU. The highest absolute and relative density fluctuations occur ahead of and in the plasma from coronal mass ejections, with the maximum values occurring between the associated interplanetary shocks and the driver gas, For the quasi-stationary solar wind, density and relative density fluctuations are highest in the plasma sheet in which the heliospheric current sheet is embedded, and lowest in the high-speed coronal hole flow. Superposed epoch analysis shows that the region of enhanced density fluctuations and its abrupt boundaries, observed in the vicinity of the heliospheric current sheet near the Sun persists to 1 AU, providing further support for the filamentary nature of the extensions of coronal streamers. The results of this study confirm the advantages of density fluctuations over density, both as tracers of solar wind flows with differing origins at the Sun and as detectors of propagating interplanetary disturbances.

FIELD: physics, communications. SUBSTANCE: invention relates to electric and radio engineering, and specifically to antenna engineering, and is intended for use as a transmitting antenna together with low-frequency medium- and high-power radio transmitters. The low-frequency antenna consists of an antenna curtain in the form of a horizontal dipole antenna with arm length L. Each arm is made of series-connected sections 1 of wire with length d. The dipole antenna is connected to a two-wire feeder 5. The antenna curtain is connected with equal intervals d to lighter-than-air aircraft 2, held by dielectric tethers 3, attached in holding containers 4, placed on the earth's surface. In the initial (non-operational) state of the low-frequency antenna, in the holding containers 4 there are covers of the lighter-than-air aircraft 2 and in folded form of the dielectric tethers 3. The cover of the lighter-than-air aircraft 2 in folded form and the two-wire feeder 5 with a dielectric tether 7 in folded state are also placed in the unfolding unit of the two-wire feeder 9. To bring into operating state, covers of the lighter-than-air aircraft 2 are filled with gas (for example, helium) and, by winding the dielectric tethers 3, 7 and the two-wire feeder 5, the antenna curtain is raised to the required height H. The process of folding the low-frequency antenna is carried out in reverse order. EFFECT: invention increases efficiency and provides a two-mode radiation mode (spatial and surface waves). 7 cl, 8 dwg

Abstract Medications that increase falls, fall-risk increasing drugs (FRIDs), are common in older adults. Two FRID definitions, the CDC Steadi-Rx and Swedish National Board of Health and Welfare, are widely accepted. We hypothesized that FRID use risk factors vary by definition in 1,352 community-dwelling older adults in the Health, Aging, and Body Composition Study (Health ABC; 2007–2008 clinic visit; 83.4±2.8 years; 54.1% women; 34.9% Black). FRID use by either definition was associated with chronic health conditions, medical care including non-FRID use, higher BMI and depression scores, and less walking exercise (all p < 0.05). Steadi-Rx FRID use was also associated with more falls, ADL difficulty, and better cognitive scores. Using stepwise multivariate Poisson regression adjusting for demographics, lifestyle/behavior factors, and comorbidity, a 1-unit increase in BMI and depression score was associated with an approximately 2% mean FRID count increase for both definitions and 7% mean FRID count increase per 1-unit increase in non-FRID count. Both definitions had a 40% and 15% lower mean FRID count, respectively, with hypertension and cardiovascular disease (CVD) history. Better cognitive scores were associated with 1% mean increase in Steadi-Rx FRID count and a mean decrease of 13% and 33% FRID count, respectively, with cancer history and having primary healthcare. In identically adjusted logistic regression, FRID use (yes/no) was associated in a consistent direction with BMI, depression score, non-FRID count, hypertension, CVD, having primary healthcare, and also less likely with low-vs-high income (OR=0.18[0.06–0.50]). Risk factors differ by FRID definition, with Steadi-Rx identifying more predictors than the Swedish definition.


Abstract:This essay approaches the theme of "impasse and democracy" through the motif of the American dream, a dream, as many have noted, unfulfilled both at home and abroad. This lack of fulfilment is here read as a structural impasse within democracy, as a sign that democracy dreams, or is a dream, because it cannot come into its own. Building toward a sustained reading of a typically neglected volume in the Freudian corpus, his collaborative study (with William C. Bullitt) of Woodrow Wilson, this essay teases out the theoretical and political implications of thinking the dream that America remains, ambivalently idling, from a psychoanalytical point of view.

Component-based product-line architectures (PLAs) must support two operations: application configuration - the construction of valid application specifications - and application generation - the compilation of specifications into executable applications. Whereas configuration is a combinatorial task involving advanced knowledge-based reasoning, generation is a deterministic compilation process. This suggests an application synthesis model where configuration and generation are carried out separately by interoperable tools. To this end, we introduce a PLA development toolkit which includes a constraint-based configuration language and an aspect-based generation language supporting the same architecture model. The toolkit imposes dual PLA implementations consisting of a configuration program and a generation program. The compilation of the configuration program yields an interactive configurator used to produce valid configurations at run-time. Valid configurations are then compiled by the generator with the generation program to produce Java applications. Overall, this model allows the use of powerful configuration and generation technologies - namely, constraint programming and aspect-oriented programming - while enforcing view consistency and tool interoperability.


This work discusses the electron transport mechanisms that we obtained as a function of the density of amorphous carbon (a-C) ultra-thin films. We calculated the density of states (total and projected), degree of electronic states' localization, and transmission function using the density functional theory and nonequilibrium Green's functions method. We generated 25 sample a-C structures using ab-initio molecular dynamics within the isothermal-isobaric ensemble. We identified three transport regimes as a function of the density, varying from semimetallic in low-density samples ( ≤2.4 g/cm3) to thermally activated in high-density ( ≥2.9 g/cm3) tetrahedral a-C. The middle-range densities (2.4 g/cm3 ≤ρ≤ 2.9 g/cm3) are characterized by resonant tunneling and hopping transport. Our findings offer a different perspective from the tight-binding model proposed by Katkov and Bhattacharyya [J. Appl. Phys. 113, 183712 (2013)], and agree with experimental observations in low-dimensional carbon systems [see S. Bhattac...

I became a living donor transplant patient for my son Shaun, ten and a half years ago. He suffered from Cystic Fibrosis and was twenty-four years old when his health began to deteriorate rapidly. We agreed as a family that if there was any way we could help Shaun we would do anything in our power to. Shaun's consultant at the Royal Brompton Hospital consented to our attempt to provide a living donor lung transplant in an effort to save his life. My eldest son Bobby and I donated lung to Shaun. The right lower lobe was taken from Bobby and the left lower lobe was taken from myself, in an effort to give two healthy lungs to Shaun. Sir Magdi Yacoub and his team at Harefield hospital performed the operation.

Retranslating Lin Yu-tang is to meet the need of studying Lin Yu-tang in a deep-going way and the implementation of the strategies of cultural development of China.The existing translated versions of Lin Yu-tang's English works have both imperfection and good expressions.With the discipline of translation ethics and the absorption of the rational core of the theory of retranslation based on filtered translational accumulation,which can be epitomized in the model of "filtering—integrating—recreating—surpassing",we can offer theoretical guidelines for the retranslation and promote the cultural accumulation and development.


We describe a mathematically based algorithm that can fill a spatial region with an infinite sequence of randomly placed and progressively smaller shapes, which may be transformed copies of one motif or several motifs. This flexible algorithm can be used to produce a variety of aesthetically pleasing fractal patterns, of which we show a number of examples.


There is no report up to date about treating disseminated brain metastases using whole brain radiotherapy followed by individual tumor boost. Technical difficulty, expected dismal prognosis, and lack of supporting evidences are possible reasons contributing to the lack of attention paid to this matter. This report may be a first on an aggressive brain radiation for symptomatic disseminated brain metastases, more than 40 tumor foci, using tomotherapy. The patient in question is a 44 year-old lady with advanced nonsmall cell lung cancer. Symptomatic disseminated brain metastases concurrent with progression of intrapulmonary disease developed after months of remission achieved by primary chemotherapy. Because of her relative young age and good performance status, an aggressive brain radiation was performed in a hope to deliver a better intracranial control during the period of ensuing salvage chemotherapy. A whole brain radiotherapy (WBRT) of 30 Gy in 15 fractions was delivered first and achieved a good palliative effect of ameliorating her brain edema and reducing the tumor sizes. A sequential tumor boost to all observable tumor foci was delivered three weeks after WBRT to a total dose of 56 Gy for two large masses or 50 Gy for other small masses, respectively, without incurring significant toxicity. The treatment to the patient is quite successful, taking into consideration of its good palliative effects as well as low toxicity. The physic profile showed that tomotherapy is good at delivering a highly conformal therapy to targets while avoiding critical structures, e.g. eyes.

Humans can incrementally learn to do new visual detection tasks, which is a huge challenge for today's computer vision systems. Incrementally trained deep learning models lack backwards transfer to previously seen classes and suffer from a phenomenon known as $"catastrophic forgetting."$ In this paper, we pioneer online streaming learning for object detection, where an agent must learn examples one at a time with severe memory and computational constraints. In object detection, a system must output all bounding boxes for an image with the correct label. Unlike earlier work, the system described in this paper can learn this task in an online manner with new classes being introduced over time. We achieve this capability by using a novel memory replay mechanism that efficiently replays entire scenes. We achieve state-of-the-art results on both the PASCAL VOC 2007 and MS COCO datasets.


The relation between multilayer thin film strain and film thickness variations is analyzed on the base of thin film stress formula and micro-bending principle of elasticity. Theoretic model for the relation between variations of substrate curvature and film thickness is established and the expression for the thickness non-uniformity variation of thin film-layer is obtained. If the variation of optical path length is identical, it will lead center wavelength shift only, but the variation of optical path length is non-identical and it will lead to not only center wavelength shift but also degradation of transmission curve. For a 100GHz filter, simulated result was that center wavelength and bandwidth decreased by 0.977nm and 0.19nm,respectively when the thickness of substrate is reduced from 10mm to 1.0mm. Then, random errors of thin film thickness are introduced to simulate spectrum. The results are that center wavelength, ripple and peak insertion loss increased by 1.066nm, 0.36dB, 0.32dB,respectively. The transmission curve is further degraded. The results show that the irregularity of thin film thickness variation caused by substrate curvature changes is one of the main reasons of spectrum degradation of the narrow band filter.

In a Majorana basis, the Dirac equation for a free spin one-half particle is a 4x4 real matrix differential equation. When including the effects of the electromagnetic interaction, the Dirac equation is a complex equation due to the presence of an imaginary connection in the covariant derivative, related with the phase of the spinor. In this paper we study the solutions of the Dirac equation with the null and Coulomb potentials and notice that there is a real matrix that squares to -1, relating the imaginary and real components of these solutions. We show that these solutions can be obtained from the solutions of two non-linear 4x4 real matrix differential equations with a real matrix as the connection of the covariant derivative.


Mammalian central nervous system( CNS) cannot regenerate after injury,which main due to the role of glial scar mechanical obstruction,the deficiency of promoting nerve growth factor and the presence of the inhibitors. The presence of inhibitors is considered to be the most important reason. Nogo,as the most important material to suppress the central nervous system regeneration,is getting more attention. In recent years,more and more studies show that Nogo not only inhibits the regeneration of injured CNS,but also plays an important role in the normal physiological process. Nogo on the inhibition of axonal growth and normal physiological processes have involved in a variety of signaling molecules and signaling pathways. It is important to make it clear how Nogo works through different signal transduction pathways caused by the biological effects, which has a crucial role for the early break of CNS regeneration problem. Therefore,Nogo and the downstream signaling pathway of its receoptor-NgR have been reviewed in this papper.


We present a detailed real-space spin-polarized scanning tunneling microscopy (SP-STM) study of the magnetic domain structure of Gd(0001) films epitaxially grown on W(110). To find optimal preparation conditions, the influence of the substrate temperature during deposition and of the post-growth annealing temperature was investigated. Our results show that the lowest density of surface defects, such as step edges as well as screw and edge dislocations, is obtained for room temperature deposition and subsequent annealing at 900 K. SP-STM data reveal small-sized magnetic domains at lower annealing temperatures, evidently caused by pinning at grain boundaries and other crystalline defects. The coverage-dependent magnetic domain structure of optimally prepared Gd films was systematically investigated. For low coverage up to about 80 atomic layers (AL) we observe µ m-sized domains separated by domain walls which are oriented approximately along the [1¯10] direction of the underlying W substrate. Above a critical film thicknesses Θ crit ≈ (100 ± 20) AL, we identify stripe domains, indicative for a spin reorientation transition from in-plane to out-of-plane. In agreement with existing models, the periodicity of the stripe domains increases the further the coverage exceeds Θ crit . While the orientation of the stripe domains is homogeneous over large distances just above Θ crit , we find a characteristic zig-zag pattern at Θ & 200 AL and irregular stripe domains beyond 500 AL. Intermediate minima and maxima of the magnetic signal indicate the nucleation of branching domains. The results are discussed in terms of various contributions to the total magnetic energy, such as the magneto-crystalline, the magneto-static, and the magneto-elastic energy density.

Background: Intestinal parasitic infections (IPIs) are still considered a public health problem of mankind, particularly in immunocompromised patients. We aimed to determine the prevalence of IPIs with an emphasis on immunocompromised patients in a referral hospital in Tehran Province, Iran. Methods: In this cross-sectional study, 442 fecal specimens were collected randomly from patients, referred to Baqiyatallah Hospital in Tehran Province, Iran from May to September 2020. The collected specimens were examined using wet-mount, trichrome and modified Ziehl-Neelsen staining, formalin-ether concentration, and agar plate culture. Results: The prevalence of IPIs was found 17.0% (95% CI: 13.6–20.8%). The prevalence of protozoan parasites (16.3%; 95% CI: 13.0–20.1%) was significantly higher than helminthic parasites (0.7%; 95% CI: 0.1–2.0%). Blastocystis spp., Giardia lamblia, and Entamoeba coli were the most common intestinal protozoan with a prevalence of 12.2%, 1.6%, and 1.4%, respectively. E. histolytica/E. dispar/E. moshkovskii, Iodamoeba bütschlii, Cryptosporidium spp., Chilomastix mesnili as protozoan species and Hymenolepis nana, Dicrocoelium dendriticum, and Ascaris lumbricoides as helminthic species were the other detected parasites. Multiple logistic regression revealed a significant association of IPIs infections with stool consistency and the status of immune system. Conclusion: The prevalence of IPIs among the patients who are immunocompromised was significantly higher than immunocompetent patients (P< 0.05). Periodic stool examinations for screening of IPIs should be included as a part of routine medical check-up in these patients.


Colombia has presented positive indicators in terms of generation of enterprise, and this is proved by the results published in recent years in the GEM report, however, this increase in entrepreneurship is not reflected in a direct economic growth, and to increased levels of innovation in the country.
In Latin America the level of innovation of entrepreneurs is considerably lower than the presenting entrepreneurs comparable regions of Asia and Eastern Europe, as a result the growth of the Latin American business sector is much slower and the ability to generate employment is much lower and therefore the boost to economic development in their countries too. This is mainly due to the deficiency in the formation of human capital, the low competitiveness of basic services-such as communication, transport and logistics, and an unfavorable economic and institutional environment.
In contrast to the above in Colombia entrepreneurship is taking place in the consumer area, Colombia has only 24% of companies in the processing sector and less than 6% for innovation. This reflects how the country needed to invest more in the research area, to make the enterprises generated innovative, and therefore may be able to compete with international products.
While efforts have been made from the part of entities involved in the development of policies that promote innovation, further efforts are needed to increase the innovative enterprises produced by the Colombians.


The impact parameter method is used to investigate the excitation of the (2p53s)1P of Ne in He+Ne collision. It is assumed that excitation occurs mainly by a transition from the B2 Sigma state to the excited C2 Sigma state in the vicinity of the pseudo crossing of their respective potential energy curves. The potential parameters of Sidis and Lefebvre-Brion (1971) are adopted. The calculations which have been made at impact energies 0.7 keV and 1.58 keV are in very good agreement for tau <3 keV deg with the experimental results of Baudon et al. (1970). Limitations of the methods used are discussed.


The main goal is presentation the broad experimental research associated with the transmission of acoustic energy generated by moving objects into the water. I present the methodology of evoluation of the transmission of low frequency vibration from the mechanisms of ship into the water environment. For that purpose the research of vibration distribution over ship's hull were conducted along with the hydroacoustic field. The underwater sound measurements were performed both for sailing condition and during anchorage. The hull is source of complex surface shape inducing waves of different frequencies depending on the working parameters of ship's machinery. As a result of mechanical incitement of the hull's surface a complex distribution of vibration is created depending on vibration spectra of the primary sources as for the main propulsion units, generators or other mechanisms. This research allowed to determine the transmission coefficient for the mechanical vibration energy going through the ship's hull ...


• Participants (N=17, 11 female) were seated on the MPI Motion simulator2 and used a steering wheel to control lateral motions on an arc (diameter = 5.4m). • The lateral velocity was proportional to the steering wheel angle. • A target was briefly flashed in total darkness and participants were asked to directly move in front of that target. • Target distances = 40°, 55° and 70° each to the left and to the right.

In clinical medicine, the contrast-enhanced ultrasound(CEUS) has been a commonly used imaging modality for diagnosis of breast tumor. However, most researchers in computer vision field only focus on B-mode ultrasound image which does not get good results. To improve the accuracy of classification, first, we propose a novel method, i.e., a Temporal Sequence Dual-Branch Network(TSDBN) which, for the first time, can use B-mode ultrasound data and CEUS data simultaneously. Second, we designed a new Gram matrix to model the temporal sequence, and then proposed a Temporal Sequence Regression Mechanism (TSRM), which is a novel method to extract the enhancement features from CEUS video based on the matrix. For B-mode ultrasound branch, we use the traditional ResNeXt network for feature extraction. While CEUS branch uses ResNeXt + R(2 + 1)D network as the backbone network. We propose a TSRM to learning temporal sequence relationship among frames, and design a Shuffle Temporal Sequence Mechanism(STSM) to shuffle temporal sequences, the purpose of which is to further enhance temporal information among frames. Experimental results show that the proposed TSRM could use temporal information effectively and the accuracy of TSDBN is higher than that of state-of-art approaches in breast cancer classification by nearly 4%.


The power supply system that will energize the superconducting magnets in the ISABELLE 400 × 400 GeV accelerator must supply various voltages and currents. The voltages for the correction winding range from ten to one hundred twenty-five volts unipolar and bipolar with current rating of 50 to 300 amperes. The main field winding requires voltages from 90V (at flattop) to 600V during maximum ramp rate or acceleration cycle. The power supplies are programmable over their full range of output current with a reproducibility error varying from +10 ppm to +400 ppm of full scale. Included within the reproducibility error are the long and short term stability requirements of the power supplies. The purpose of this paper is to define some of the design goals and outline the approach taken in reaching these goals.


that it is possible to form a general estimate of the absolute magnitudes of the components of a double star from the positions which the system occupies on the several charts accompanying the paper—to decide at least whether the pair is a giant or a dwarf ; conversely, if the spectral classes and the inequality in magnitude between the components, but not their parallax be known, from the position which the double star would normally assume on Fig. 4 {ibid., p. 189), a fair approximation to the absolute magnitudes of its components, and hence an hypothetical value of the parallax of the system, may be derived. This method has been applied to assign what is here termed the spectral groups and to determine the parallaxes and projected linear separations of 153 visual double stars for which complete information concerning the spectral classes of their components was contained in the aforementioned paper but for which no acceptable parallaxes were known. As a check on the method, it has been extended to the cases of 85 systems discussed in the preceding paper for which reliable knowledge regarding the parallaxes as well as the spectral types was avail able. The (hypothetical) spectral parallaxes derived for these systems, in a large majority of cases, are found to be in good agreement with the previously known parallaxes. Several other matters, chief among which are two possible orders of evolution pursued by double stars of different spectral characteristics, are also considered in the present paper. August 18, 1923.

Data obtained from UHF Radar observation of direct-lightning strikes to the NASA F-106B airplane have indicated that most of the 690 strikes acquired during direct-strike lightning tests were triggered by the aircraft. As an aid in understanding the triggered lightning process, a wide bandwidth electric field measuring system was designed for the F-106B by implementing a clamped-detection signal processing concept originated at the Air Force Cambridge Research Lab in 1953. The detection scheme combines the signals from complementary stator pairs clamped to zero volts at the exact moment when each stator pair is maximally shielded by the rotor, a process that restores the dc level lost by the charge amplifier. The new system was implemented with four shutter-type field mills located at strategic points on the airplane. The bandwidth of the new system was determined in the laboratory to be from dc to over 100 Hz, whereas past designs had upper limits of 10 Hz to 100 Hz. To obtain the undisturbed electric field vector and total aircraft charge, the airborne field mill system is calibrated by using techniques involving results from ground and flight calibrations of the F-106B, laboratory tests of a metallized model, and a finite-difference time-domain electromagnetic computer code.


"Carbon peaking" and "carbon neutralization" are major strategic decisions made by the CPC in coordinating the international and domestic situations. Electric energy substitution, as the main form of clean energy utilization, is one of the core paths to make the achievement the goal of carbon neutrality in China. This paper reviews the development process of electric energy substitution at home and abroad, and summarizes the challenges faced by China in promoting electric energy substitution. In view of the lack of theories and analysis tools in the current path planning of electric energy substitution, a macro micro coupling comprehensive evaluation model framework of electric energy substitution is proposed: first, a typical industry database is built to provide a basis for the analysis of electric energy substitution in various industries; second, the shared social economic paths (SSPs) scenario parameters will be localized in China as the output of social and economic development scenarios; third, the technical parameters will be localized to achieve the calibration of micro parameters; the fourth is to couple macro and micro markets and establish a dynamic feedback and two wheel drive mechanism The research will help to improve the theoretical system in the field of electric energy substitution and provide scientific methodology support for the stable and orderly implementation of electric energy substitution.


In the past decade, the functional, competency-based approach has come to dominate ESL curriculum development. Though the approach is widely praised, some ESL specialists have recently criticized competency-based "survival ESL." This article examines theoretical and practical deficiencies in how curricular objectives are selected for the functional approach, the central role of values in functional curricula, and limitations in validating tests of functional competence. It is argued that these problems seriously undermine efforts to evaluate the effectiveness of ESL programs using functional curricula. These issues are illustrated through an analysis of the functional curricula of the U.S. Refugee Processing Centers, the largest survival ESL program ever created to prepare immigrants for resettlement in America. In the past decade, functional, competency-based curricula have become the dominant approach to language curriculum development. The focus of wide praise (e.g., Chamot, 1983; Findley & Nathan, 1980; Munby, 1978; Widdowson, 1978; Wilkins, 1976), competency-based curricula have been called "the most important breakthrough in adult ESL" (Center for Applied Linguistics, 1983b, p. 1), and they are used in many language programs as well as in adult basic education (ABE). In Europe, functional competencies are the basis for the Council of Europe syllabus (van Ek, 1977). The most important ABE program in the United States, the heavily promoted Adult Performance Level (APL) project (see Northrup, 1977) of the U.S. Office of Education and the University of Texas, employs a functional approach. In ESL, refugee programs in Southeast Asia and in the United States also have adopted functional curricula.


forms of democratic activities, for example, adaptive strategies of the excluded, guerrilla gardening, or micro-forms of activism. While such activities often do not result in a broader political change, they may have consequences for connectivity within the political system. The book by Hendriks, Ercan, and Boswell excellently grasps the democratic potential that such activities may offer. However, the book also has some weaknesses. It does not mention the additional burden that democratic mending can put on citizens. Democratic repair requires effort, time, and the ability to act, all of which are structurally constrained and inaccessible to many. The experiences of the Covid-19 pandemic provide further insights into the costs that such everyday actors needed to bear. Ordinary citizens, street-level administrators, and critical workers have been at the first front of the pandemic response. They have lifted much of the emotional, physical, and logistical burden. Consequently, the book misses the opportunity to analyse what should happen when everyday actors are no longer able to engage in a democratic repair. Further, it is unfortunate that all the cases that the book analyses focus on the "Western" world, with two cases in Australia and one in the UK. As a result, the book does not analyse how democratic mending can look in a context different from an established democratic regime. To summarize, the book offers a stimulating argument that will be of interest to anyone working on modern democracy and democratic repair. It also will be highly interesting to anyone looking for examples of the impact of interpretative methodologies and grounded approaches in normative theorizing. However, thanks to the elegant stitching metaphor that connects the conceptual work and case studies, the book will be of relevance to any reader curious about the understudied aspects of democratic life.


court or field is empty. Coaches and teachers primarily focus instruction around on-the ball skills and tend to overlook the importance of how to engage players in fun game like practices, which emphasize the tactics of supporting the ball carrier or creating space. In this paper, we offer three modified games that provide students' opportunities to explore methods for creating space, moving to open space, and advancing towards the goal. Each game includes a diagram, and a brief description of goals, conditions, and factors for modifying game complexity.

Better sintering process for sintering particle reinforce iron matrix composite was investigated.The results show that the sintering process of continue current directly heating and cycle current preservation temperature not only shortens sintering time but also improves greatly materials properties.Properties of iron matrix composite increases and then decreases with the content of particle which is respectively 5%,10%,15%,20%.The properties of composites are the best when the content of particle is between 10% and 15%.In addition,the best effect of volume ratio relates to the particle size.


A computational fluid dynamics–simultaneous reaction model (CFD–SRM) coupled model has been proposed to investigate the effects of different contents of aluminum, manganese and silicon in slag and liquid steel, the arrangement of bottom blowing tuyeres and the height ratio of slag and metal on the slagmetal reactions and desulfurization efficiency in gas-stirred ladles. The results show that as the aluminum is added into liquid steel, both the desilication rate and demanganization rate decrease, and the desulfurization rate increases rapidly. Meanwhile as the initial aluminum content [%YAl]t=0 exceeds 0.01 mass%, the desulfurization efficiency increases slowly. With the increase of initial silicon content [%YSi]t=0, the demanganization rate decreases, while the desulfurization rate increases. When the [%YSi]t=0 exceeds 0.5 mass%, the effect of [%YSi]t=0 becomes weak. As well, the variations of manganese content in liquid steel has little effect on the desulfurization efficiency. For the initial content (%Yi)t=0 in slag, with the decreasing of , the desulfurization rate increases rapidly, but as the is less than 23.0 mass%, the desulfurization efficiency increases slightly. With the increasing of the (%YMnO)t=0, the desulfurization efficiency decreases rapidly. Furthermore, the dual blowing gives higher desulfurization efficiency in comparison with the center blowing or eccentric blowing with one tuyere. With the increasing of height ratio of slag and metal (h/H), the desulfurization efficiency increases, but when the h/H exceeds 0.4, the desulfurization efficiency changes weakly.

In reference to Eliot Marshall's News & Comment article of 9 August ([p. 731][2]), it is difficult to understand why drug-abuse neuroscientists are concerned about being fully integrated into the National Institutes of Health (NIH) peer review system. Those scientists have conducted cutting-edge research on and have made major contributions to our understanding of brain and behavior: They predicted (from behavioral studies) the existence of and then identified several classes of opiate receptors, thereby revolutionizing the concept of neurotransmitters and brain function; they specified and cloned the receptors for every major drug of abuse (and discovered several completely novel ligands); they advanced the conceptualization of drug dependence as a biologically mediated disease; and they made fundamental discoveries involving the mechanisms of analgesia, tolerance and dependence, pleasure and pain, and reward and punishment, and then used all of this information to develop new treatments for drug abuse, alcoholism, nicotine addiction, and pain. In light of these and other impressive accomplishments, they should be able to compete successfully against and take their place among the best in the world in the life sciences.

Marshall's article suggests that the distinction between psychobiology and biopsychology is fuzzy and hard to explain, even by NIH staffers. This portrayal of arbitrariness in naming these two neuroscience specialties is not justified. Psychobiology emphasizes biologically dependent variables (for example, brain states) as functions of psychological or behavioral independent variables. Biopsychology emphasizes psychologically or behaviorally dependent variables as functions of biological independent variables (for example, drug states). The two approaches to brain and behavior are complementary in that it is impossible to establish a causal link or isomorphism between a behavioral state and a brain state without both approaches. It is high time that the two were combined in NIH study sections.

The paper considers data security and privacy issues in intelligent transportation systems which involve data streams coming out from individual vehicles to road side units. In this environment, there are issues in regards to the scalability of key management and computation limitations at the edge of the network. To address these issues, we suggest the formation of groups in the vehicular layer, where a group leader is assigned to communicate with group members and the road side unit. We propose a lightweight permutation mechanism for preserving the confidentiality and privacy of sensory data.


The pollution evaluation on heavy metals of farmland soil in Linzi was conducted by applying the fuzzy comprehensive - weighted average model. 10 representative townships in Linzi were selected in this study, the contents of 7 kinds of heavy metals Cu, Zn, Pb, Cd, Cr, As, Hg) in soil were determined separately, and then fuzzy comprehensive assessment was used according to the determination results. The results show that soil quality of Zhutai town and Qiling town was the worst, soil quality were all the grade III and preferred to the grade IV, the others were the grade I or the grade II. Pollution of Zn in 7 kinds of heavy metals was the most common, followed by As and Cr.


Piezoelectric actuators are widely used in micro/nanoscale robotic manipulators. Due to its hysteresis and dynamic-related nonlinearity, accurate displacement tracking control of piezoelectric actuator is challenging. Besides, in some low-cost practical systems with low sampling rate, transmission delay causes mismatches between feedback and real displacement, further increasing the challenge in tracking control. In this article, a neural network-based model predictive controller (MPC) is proposed for precise tracking control of piezoelectric actuator's displacement in situation where feedback is slow and delayed. The prediction model is based on a nonlinear-autoregressive-moving-average-with-exogenous-inputs framework, which outputs entire prediction horizon of future displacement in a single time, and is fulfilled by a multilayer feedforward neural network. An extended Kalman filter-based estimation for displacement is introduced to relieve the influence of feedback delays so as to improve dynamic performance of the controller. Another neural network is trained to provide initial values for MPC to reduce computation costs and improve performance in dynamic tracking. In a series of tracking experiments, the effectiveness of proposed controller is verified.


Although cell surface charge has been thought to reflect changes in the structure and function of a cell membrane, conventional instruments'~ used for cell electrophoretic mobility are manually operated and take a long time for the measurement. By the manual instrument, it is difficult to obtain reproducible results even under the control of experts. Recently, a fully automatic instrument was developed and has been applied to colloidal particles such as pulp.2~ The present paper is the first report on the biological application of this instrument to blood corpuscles and experimental tumor cells. Materials and methods. Preparation o f cells. Blood was collected with a heparinized syringe from healthy human volunteers and Donryu rats (12-16 weeks old). Sheep erythrocytes were purchased from Tohyo-kessei Co., Ltd., Tokyo, Japan. Erythrocytes were washed three times with phosphate-buffered saline (PBS, pH 7.4) and suspended in 0.145 M NaCI solution (pH 7.0, adjusted with NaHC03). For the separation of lymphocytes, the heparinized blood was layered on Ficoll-Conray 400 (specific gravity, 1.081) and centrifuged at 400 g for 30 min at room temperature. Lymphocytes at the interface of the layer were collected and washed three times with PBS. Peritoneal exudate cells were collected from the abdominal cavity of rats, 4 days after the intraperitoneal injection with 10 ml of 0.1% glycogen solution. Macrophages were separated from the peritoneal exudate cells following the same procedure as lymphocytes. Sarcoma-180 and glioma (SR-RSV) were transplanted intraperitoneally in CD-1 and CDF1 mice, respectively. These tumor cells were collected from the abdominal cavity of the mice and washed four times with PBS. After being washed with the modified Zeiller and Hannig medium,3> > * * * * >


As outcomes following heart transplantation have improved significantly over the last years, chronic kidney disease has become an increasingly prevalent complication in this population. Polyomavirus-associated nephropathy (PVAN) of native kidneys has also been recognized increasingly as a cause of kidney failure. We report the first case of PVAN occurring in the native kidneys of a solid-organ transplant recipient in Croatia as the eighth case described in the literature worldwide. A 65-year-old female with dilatative cardiomyopathy and good kidney function had a heart transplanted in 2012. Initial immunosuppressive therapy consisted of antithymocyte immunoglobulin with cyclosporine, mycophenolate mofetil and corticosteroids. Soon after transplantation, her kidney function began to fail progressively. Biopsy of the native kidneys revealed PVAN, and everolimus was introduced in immunosuppressive therapy. Nevertheless, her renal dysfunction progressed and she is now being evaluated for cadaveric kidney transplantation. PVAN should be considered in the differential diagnosis of new-onset renal failure following non-kidney solid organ transplantation. Early diagnosis is essential for prevention of irreversible renal damage.
