Spatial heterogeneity of soil salinity in the typical area of Yutian oasis was analyzed by using geostatistics.Results indicated that soil salinization in Yutian oasis was severe and soil salinity accumulated in surface soil layer.The variational amplitude of soil salinity in surface soil layer was the highest because of the disturbance of human activities.The spatial correlation of soil salinity in the 0—5 cm soil layer was strong;in the 5—30 cm soil layer,in the second place;and in the 30—70 cm soil layer,relatively low.In the horizontal direction from east to west,soil salinity in the 0—30 cm soil layer manifests an increase and decrease trend,while soil salinity in the 30—70 cm soil layer gradually declined.Soil salinity was high in the northern and southern parts of the study area and low in the interior part.In vertical direction,soil salinities in saline land,highly coved grassland and medially coved grassland were relatively high and gradually decreased from soil surface to lower soil layer.Soil salinity in saline land was the highest,the variational amplitude of soil salinity in highly coved grassland was greater than that in medially coved grassland,soil salinities in farmland and lowly coved grassland were relatively lower with low variational amplitudes.The main factor for the spatial heterogeneity of soil salinity in the oasis was the difference of soil and water movement in different landforms and land uses.


In this paper, a new low-IF architecture for an on-chip implementation of a cable modem receiver is presented. In this receiver, a low power, area efficient digital filter is used to achieve 60dB adjacent channel rejection. A new adaptive analog-digital image-reject technique is also used, which improves the image-rejection ratio to 57dB. Therefore, high-Q, off-chip, SAW filters are not required. Simulations show that a signal-to-interference ratio of 34dB is achieved for a 256QAM transmitted signal.


We study the distributionally robust linearized stable tail adjusted return ratio (DRLSTARR) portfolio optimization problem, in which the objective is to maximize the worst-case linearized stable tail adjusted return ratio (LSTARR) performance measure under data-driven Wasserstein ambiguity. We consider two types of imperfectly known uncertainties, named uncertain probabilities and continuum of realizations, associated with the losses of assets. We account for two typical combinatorial trading constraints, called buy-in threshold and diversification constraints, to reflect stock market restrictions. Leveraging conic duality theory to tackle the distributionally robust worst-case expectation, the proposed problems are reformulated into mixed-integer linear programming problems. We carry out a series of empirical tests to illustrate the scalability and effectiveness of the proposed solution framework, and to evaluate the performance of the DRLSTARR-constructed portfolios. The cross-validation results obtained using a rolling-horizon procedure show the superior out-of-sample performance of the DRLSTARR portfolios under an uncertain continuum of realizations.


ABSTRACT Water quality control is affected by several factors such as climate change or the creation of an ecological park for human convenience. The Four-River restoration project of Korea is a government enterprise to solve a variety of problems, such as preventing floods, securing water resources, water quality management, and encouraging re-creation of land. It is evidence that technical developments and the concern of the government have sharply increased for water quality management. In particular, the phenomenon of eutrophication can cause various difficulties in drinking water treatment and water use. Accurate and reliable algal bloom forecasting models will prove very useful in ensuring sustainable water supply and proper water management in the near future. In this paper, a new method based on wavelet transforms and artificial neural networks was adopted for chlorophyll-a concentration forecasting 1, 3 and 7 days ahead. First, 12 models for forecasting chlorophyll-a concentration by combining wa...


Foreign direct investment ( FDI ) or foreign investment refers to the net inflows of investment to acquire a lasting management interest (10 percent or more of voting stock) in an enterprise operating in an economy other than that of the investor. It is the sum of equity capital,other long-term capital, and short-term capital as shown in the balance of payments. It usually involves participation in management, joint-venture, transfer of technology and expertise. There are two types of FDI: inward foreign direct investment and outward foreign direct investment, resulting in a net FDI inflow (positive or negative) and "stock of foreign direct investment", which is the cumulative number for a given period. Direct investment excludes investment through purchase of shares.

We present a timing analysis of the eclipsing post-common envelope binary (PCEB) DE CVn. Based on new CCD photometric observations and published data, we found that the orbital period in DE CVn has a cyclic period oscillation with an amplitude of 28.08 s and a period of 11.22 years plus a rapid period decrease at a rate of . According to the evolutionary theory, secular period decreases in PCEBs arise from angular momentum losses (AMLs) driven by gravitational radiation (GR) and magnetic braking (MB). However, the observed orbital decay is too fast to be produced by AMLs via GR and MB, indicating that there could be another AML mechanism. We suggest that a circumbinary disk around DE CVn may be responsible for the additional AML. The disk mass was derived as a few ×10−4–10−3 M⊙ , which is in agreement with that inferred from previous studies in the order of magnitude. The cyclic change is most likely the result of the gravitational perturbation by a circumbinary object due to the Applegate's mechanism failing to explain such a large period oscillation. The mass of the potential third body is calculated as . Supposing the circumbinary companion and the eclipsing binary are coplanar, its mass would correspond to a giant planet. This hypothetical giant planet is moving in a circular orbit of a radius of ∼5.75(±2.02) au around its host star.

Technological advances are taking a major role in every field of our life. Today, younger generation is more attached to technology, immerging it mostly for social purposes. Therefore, the importance of its existence cannot be ignored. For that, it is the time for every mentor to apply technology to education. Instructors from different majors need to realize that integrating technology into education is a powerful tool that helps them moderate their course, but never a replacement to their existence. This paper's interest is to deliver a personal experience to other instructors on how to correctly use technology for educational purposes. One way of clarifying this point is to shed light on a very common social application that is WhatsApp. It is a social application available on every smartphone that is usually used as a social medium among users from different generation. This paper used WhatsApp as an application that can associate technology with learning and teachers' moderation and collaboration under one roof, and that is by applying Mobile learning. One main question to rise at this point is whether students are going to be collaborative or not with their teacher in applying technology into education. There will be an anticipated approach from this paper on both Mobile learning and WhatsApp, that is to reach an agreement that Mobile learning is essential and adds value to the educational material we have in hand. Great examples from my own data are going to be presented to encourage others to predict new ways that can be added to my effort and others as well. The result hoped for after this paper is to be able to answer any digital immigrants' questions and help them to be more confident with technology.


A 13-year-old boy who underwent left myringotomy and grommets insertion under sevoflurane anesthesia, with midazolam (1 mg), fentanyl (100 mcg) and propofol (150 mg) induction, suddenly became very agitated and combative in the postanesthesia care unit (PACU), kicking and thrashing around, and showing paranoid delusions and having hallucinations. EA/emergence delirium (ED) was diagnosed. He accidentally removed his i.v. catheter, which was immediately replaced after which a bolus of propofol 30 mg was administered. However, he became even more agitated, kicking and punching medical and nursing staff. He did recognize his mother who was by now extremely alarmed and agitated. He was given i.v. midazolam 4 mg total, morphine 3 mg and further 30 mg boluses of propofol to a total of 150 mg, but without any lasting effect. Subsequently, he was administered i.v. dexmedetomidine 0.4 mcg/kg over about 6 min with almost immediate resolution of the EA/ED. He subsequently emerged from a brief period of restful sleep, calm, alert and orientated without any signs of delirium. He was subsequently discharged after 30 min from the PACU to the ward.


Bluetooth Low Energy (BT LE) is a low power air interface technology recently released by the Bluetooth Special Interest Group (BT SIG). As a promising radio, BT LE realizes many designing features to fulfill foreseeable requirements of short range communication, such as fast device discovery, power-saving transmitting, encryption and authentication, etc. In this paper, we focus on the modeling and performance analyzing of the device discovery process in BT LE networks. A general model for device discovery on multi-channel is proposed primarily, which is then tailored and simplified for the BT LE case, where three broadcasting channels are used. Via theoretical analysis, our study reveals that some potential pitfalls are residing in the current version of BT LE specification, i.e. improper parameter settings can significantly deteriorate the device discovery latency and increase meaningless energy consumption. We accordingly propose several strategies seeking ways to tackle the problem. The results of extensive simulation show that our strategies can largely reduce undesirable latency and effectively improve the efficiency of device discovery in BT LE networks.

Let G be a connected complex reductive group, B ⊂ G a Borel subgroup, and T ⊂ B a maximal torus. A G-variety is called spherical if it is normal and contains a dense B-orbit. Examples include flag varieties, symmetric spaces, and group embeddings (Section 2). For an up-to-date discussion of spherical varieties, and a comprehensive bibliography, see [Ti] and [Pe]. If X is a spherical G-variety, then it has only a finite number of B-orbits and G-orbits. In particular, T acts on X with only finitely many fixed points. These features make spherical varieties particularly well suited for applying GKM theory, a set of tools developed by GoreskyKottwitz-MacPherson in the topological setting [GKM], and later generalized to equivariant Chow groups [Br2], equivariant algebraic K-theory [VV], and equivariant operational theories [G3], [G4]. Through this method, substantial information about the geometry and topology of a spherical variety can be obtained by restricting one's attention to the induced T -action.

Figure 1: Three marine systems I have worked with. Top Left: Autonomous kayak on Charles River, Massachusetts. Top Right: OceanServer Iver2 in the Bedford Basin, Nova Scotia. Bottom: WAM-V at the RobotX competition, Singapore. There is tremendous potential for autonomous marine systems. The underwater world represents one of the most unique opportunities for scientific discovery and is a natural application for robotics since it is so inhospitable to humans. In spite of this, underwater robotics has received orders of magnitude less research focus than terrestrial or even space applications. Certainly the challenges are significant. For example, sensing underwater is very limited. Cameras are only suitable at very short ranges and in clear water, sonars are low resolution and typically noisy, and GPS signals do not penetrate the water beyond a few centimeters depth. Additionally, communicating underwater is very difficult and usually restricted to the acoustic frequencies. Ideally, a network or marine robots could be deployed rapidly to perform a variety of tasks, such as offshore infrastructure maintenance, environmental disaster recovery, persistent monitoring, underwater minehunting and removal, and ocean sampling with variable degrees of human intervention. Progress towards this goal requires advances in:


Monte S. Nyman. The Most Correct Book: Why the Book 0/ Mormon Is the Keystone Scripture. Salt Lake City: Bookeraft, 1991. vii + 152 pp., subject index. $10.95. Reviewed by Brian M. Hauglid This small book takes an innovative approach to Joseph Smith's well-known slalOmen!: "I told the brethren that the Book of Monnon was the most correct of any book on eanh, and the keystone of our religion, and a man would get nearer to God by abiding by its precepts, than by any other book.'" The author divides the statement (and the volume) into three component parts: (1) "the most correct of any book on earth"; (2) "the keystone of our religion"; and (3) "precepts to bring one nearer to God" With the statement as the main premise, the author then extracts from D&C 20:8-16 a unique core of evidences in support of the three themes. Arbitrarily. these nine verses are separated into three distinct parts and classified under one of the aoove-mentioned headings. For example, verses 8-10 are placed under the section "the most correct of any txxHc"; the author then highlights from those verses the concepts of "translation," "record of a fallen people," "fulness of the gospel," "scripture," and "ministering of angels" to substantiate the "correctness" of the Book of Mormon. The same technique is used in applying verses 11-12 to the "keystone" concept and verses 13-16 as precepts to help one get nearer to God. Primarily, the aim of this work is to "show how the Book of Monnon verifies what the Lord said on that occasion [referring to the organization of the Church] and to support the Prophet Joseph's statement." It is also to "motivate both members of the Church and those who are not yet members to study the Book of Mormon and learn its inspired message" (p.2). The author demonstrates a skillful use of sources and research ability. Every point made is carefully considered and ananged to complement the author's primary objectives. Also, a flexibility exists in which newer ideas and concepts are explored. On the one hand, the author painstakingly and cautiously analyzes key words, verses of scripture. and important principles and concepts, using significant quotes from DHC 4:461; a1so TPJS. 194. 156 REVIEW OF BOOKS ON 1llE BOOK OF MORMON 4 (1992) the General Authorities of the Church. numerous scriptural citations, and statistical information; then, on the other hand, the author seems to throw caution to the wind and explores his own insights on various subjects. Most of the volume, however, is written with the beginner in mind. Those unfamiliar with the fundamental teachings about the Book of Mormon will find this book very helpful in clarifying subjects such as the process of ttanslation, how revelation works. what scripture is. what "fulness" of the gospel means, and the Book of Mormon as a "record" instead of a history. Readers well-versed in the basics will find a more definitive statement about these already familiar concepts and many useful quotations for funher research and study. Additionally. there arc a few areas where the author depans from these fundamentals and brings out some interesting, if debatable. points. For instance, the author devotes almost an entire chapter to paralleling the events that preceded the coming of Jesus Christ to the Nephites (from the book of Mosiah 10 3 Nephi II) with very similar events that occurred, or will yet occur, from the organization of the Church in 1830 to the Second Coming of Jesus Christ. On the whole, however, ] was disappointed with this volume. Though the author meticulously establishes his points and expends a great deal of effort to prove them, ] feel the basic premise of the book lacks credibility. The idea of building a work around Joseph's statement is appealing and shows promise; unfortunately, the volume ends up being more of an attempt at a definitive study on the statement instead of an elucidation on the inspired message of the Book of Mormon. To be sure, the volume does an adequate job of using the Book of Mormon as a tool to substantiate the statement of Joseph Smith. However, I found myself asking why there would be a need to write a book that shows how the Book of Mormon "verifies" and "supports" the Prophet's statement. Does the statement req~ a confumation from the Book of Mormon 10 be credible? ]s the author trying to prove the statement or is he using the statement to prove the Book of Mormon? I felt unsure about the need for writing the volume unless it was only to create a format in which to bring together various evidences to validate either the statement or the Book of Monnon. In any event, it seems superfluous to test either by checking each against the other, especially when the author defines the statement (or the Book of Monnon) using nine verses in the Doctrine and Covenants as his NYMAN, MOST CORRECT BOOK (HAUGUD) 157 only criteria. As a result of this confusing premise, the author's intention to motivate members and nonmembers has a tendency to get lost in a sea of evidences and proofs. The statement of the Prophet does not need to be verified or supponed by the Book of Monnon. On the contrary, the statement was meant as an announcement about the imponance of the doctrines and teachings of the Book of Monnon. When viewed in this context the question should be how the Book of Monnon is the "most correct of any book," the "keystone of our religion," in tenns of its own doctrines and teachings. What are the precepts in the Book of Monnon that assist one in getting "nearer to God"? Does one go to the Doctrine and Covenants to extrapolate these imponant teachings or is it better to go to the Book of Monnon and let it speak for itself? Though the Doctrine and Covenants can cenainly illuminate many doctrines in the Book of Monnon, it is not the basis of the message that the Book of Monnon contains. Significant doctrines on which the Book of Monnon elaborates. such as faith, repentance, and atonement, become relegated in Nyman's book to some obscure place. hardly receiving any attention, while those concepts and ideas (some very loosely connected) found in the nine verses of the Doctrine and Covenants are studied at great length. There are only a few brief references to the significant teachings in the Book of Monnon, which leaves one wondering again whether the main objective is flawed. Dr. Roben J. Matthews wrote an insightful and succinct article on the statement made by the Prophet. Matthews observes that the Prophet wrote his statement in reflection and that "we can have unshaken confidence that it conveys just what he wanted it to say" and that it "accurately reflects his feelings." Matthews also separates the statement into the same three divisions but then establishes a premise which departs from that set down by the author under review. Matthews places the Slatement in its historical context by saying that the Prophet was speaking of the then-current third edition (Le. , October 1840). He states that the Prophet "no doubt had reference to the contents-the doctrines and teachings---of the Book of Monnon rather than to its grammatical construction, punctuation, and spelling. ''2 Somehow this concept is never developed, nor even introduced, in Nyman ' s volume. The author is trying to make a 2 Robert J. Matthews , A Bible! A Bible! (Salt Lake City: Bookcraft, 1990), 70. 158 REVIEW OF BOOKs ON TIlE BOOK OF MORMON 4 (1992) neat little package using the verses from D&C 20. but in limiting his analysis to the points contained in those verses, he cannot discuss the many significant doctrines and teachings (the contents) of the Book of Monnon with the same emphasis given those teachings in the Book of Monoon itself. I suggest that the statement of Joseph Smith can only be understood and appreciated in light of the doctrines and teachings of the Book of Monnon. According to Elder Boyd K. Packer, "true doctrine, understood, changes attitudes and behavior. The study of the doctrines of the gospel will improve behavior quicker than a study of behavior will improve behavior."3 President Ezra Taft Benson has said .. the Book of Monnon is the keystone of our religion, ... the keystone of our testimony, the keystone of our doctrine, and the keystone in the witness of our Lord and Savior."4 To emphasize the Savior's power, President Benson has also stated that "the Lord works from the inside out. The world works from the outside in .... The world would mold men by changing their environment. Christ changes men, who then change their environment. The world would shape human behavior, but Christ can change human nature. "5 Joseph Smith's statement, therefore, is a concise declaration that the Book of Monnon is the "most correct of any book" because it has the power to change individuals into more correct (Christlike) people. This change can only come because of better understanding Christ as the "keystone" figure of the Book of Mormon, and by applying the atonement, which embraces all of the "precepts" that bring one nearer to God. Another difficulty with the volume is the author's writing style. Although the author excels in research and analysis. progress is often impeded by dry. stilted sentences and uninspiring language. In shon. I feel this book falls far shon of enhancing our appreciation of the Book of Monnon message. In the future, it would be refreshing to see more volwnes true to the 1988 challenge Presidem Benson gave to Church writers. Addressing the issue of writing on the Book of Monnon he said, "Let us know how it leads to Christ and answers our personal 3 Boyd K. Packer, "LillIe Children," Ensign 16 (November 1986):


Significance Leaf phenology of temperate ecosystems is shifting in response to global warming. This affects surface albedo, ecosystem carbon balance, and evapotranspiration, and the response of leaf phenology to climatic drivers has therefore received particular interest. However, despite considerable effort, models have failed to accurately reproduce phenology patterns, likely because mechanistic understanding is incomplete. Here, we show that earlier leaf flushing in response to a warm winter translated into earlier leaf senescence and even earlier leaf flushing in the following year. This legacy effect of winter warming on leaf phenology has important implications for understanding and modelling leaf phenology and its impact on ecosystem functioning, especially in relation to global warming, and is likely to open new research lines. Recent temperature increases have elicited strong phenological shifts in temperate tree species, with subsequent effects on photosynthesis. Here, we assess the impact of advanced leaf flushing in a winter warming experiment on the current year's senescence and next year's leaf flushing dates in two common tree species: Quercus robur L. and Fagus sylvatica L. Results suggest that earlier leaf flushing translated into earlier senescence, thereby partially offsetting the lengthening of the growing season. Moreover, saplings that were warmed in winter–spring 2009–2010 still exhibited earlier leaf flushing in 2011, even though the saplings had been exposed to similar ambient conditions for almost 1 y. Interestingly, for both species similar trends were found in mature trees using a long-term series of phenological records gathered from various locations in Europe. We hypothesize that this long-term legacy effect is related to an advancement of the endormancy phase (chilling phase) in response to the earlier autumnal senescence. Given the importance of phenology in plant and ecosystem functioning, and the prediction of more frequent extremely warm winters, our observations and postulated underlying mechanisms should be tested in other species.


The impact of cooperative and observational training on learning motor skills has been studied separately. Investigating the impact of dyad training is a new approach that combined observational and cooperative training that has not yet been fully studied. The purpose of this study was to investigate the effect of dyad training on basketball lay-up performance. Twenty-two female students volunteered in this study. After the initial instruction, participants completed six attempts for the pre-test and were divided into two groups (control and experimental) based on pre-test scores. Lay-up shot was training in six sessions. The post-test and retention were implemented, immediately and three days after session training. For intergroup compression independent sample t-test was used, and for intragroup analysis of variance was performed, using SPSS software with p 0.05). These results showed that dyad training with 50% physical effort is more effective than individual training with 100% physical effort. Also, due to less physical effort, the risk of injury and fatigue was lower and also causes cognitive training in beginners.


A programme of Malaise trapping at sites in Portugal has been carried out in recent years by one of us (ER) and material was collected into 70 per cent ethanol. At one of these sites both sexes of a dark coloured fungus gnat, which was evidently undescribed, were found. This species had the wing venation and most other characters typical of the genus Ectrepesthoneura Enderlein, 1911 but obviously differed in structure of its male genitalia from any previously known species. It did, however, have some significant characters, especially of the male genitalia, in common with E. chandleri Caspers and these two species are considered to differ sufficiently from the other species assigned to Ectrepesthoneura to propose a new genus to include them. It is probable that some other species placed in Ectrepesthoneura, such as E. gracilis Edwards, 1928 will be found to deserve such a change of status when the world fauna of this group is better known. 2.

A pulsating fluidized bed of zeolite and rice husk was studied; were experimentally determined the minimum fluidization velocities and the influence of pulsating conditions, in the gas dynamic characteristics of the fluidized bed. The experimental study included three different beds of zeolite and one of rice husk, varying the pulse frequency in a range from 0 to 140 pulses per minute, in each bed. Is proposes a factorial experiment of two factors, diameter and pulse rate, taking six levels for frequency and three for the diameter. It was determined the equation to predict the minimum fluidization velocity for pulsating fluidized bed. The empirical equation obtained for the zeolites beds, was applied to the rice husk bed, with good results for prediction of the minimum fluidization velocity.


We investigate the electrical properties of polycrystalline silicon thin films implanted with arsenic or boron ions. Two types of post-implantation annealing have been performed on the samples: a conventional thermal annealing (CTA) and a rapid thermal annealing (RTA). We find that RTA improves the electrical properties. Measurements of gauge factors have been carried out on both films. We conclude that RTA can be applied successfully in thin film silicon integrated sensor technology


Testing for emissions of dioxins from the stack of the Columbus, Ohio Waste to Energy (WTE) municipal solid waste combustion facility in 1992 implied that dioxin emissions could approach 1,000 grams of dioxin toxic equivalents (TEQs) per year. The incinerator has been in operation since the early 1980s. Several varying activities to further evaluate or curtail emissions were conducted by local, state and federal agencies in 1994. Also in that year, US EPA`s Region 5 issued an emergency order under Section 7003 of RCRA requiring the facility to install maximum Achievable Control Technology (MACT). As part of their justification for this emergency order, Region 5 used a screening level risk assessment of potential indirect impacts. This paper describes this assessment. The exposure setting is a hypothetical dairy farm where individuals on the farm obtain their beef, milk, and vegetables from home sources. A 70-year exposure scenario is considered, which includes 45 years of facility operation at the pre- and post-MACT emission rates, followed by 25 years of impact due to residual soil concentrations. Soil dermal contact, inhalation, and breast milk exposures were also considered for this assessment. The source term, or dioxin loadings to this setting, were derived from airmore » dispersion modeling of emissions from the Columbus WTE. A key finding of the assessment was that exposures to dioxin in beef and milk dominated the estimated risks, with excess cancer risk form these two pathways estimated at 2.8 {times} 10{sup {minus}4}. A second key finding was that over 90% of a lifetime of impact from these two pathways, and the inhalation and vegetable ingestion pathways, has already occurred due to pre-MACT emissions.« less

Data from the U.S. Census Bureau and the National Center for Education Statistics indicate that Latinos lag behind non-Latinos in education and in other socioeconomic characteristics. Although there are some positive indications such as the decrease of individuals and children living in poverty and an increase in the number of individuals working in the technical, sales, and administrative support sectors, the increases have been small. Current census population estimates indicate that the Latino population will continue its very rapid rate of growth for the foreseeable future. An overview of salient sociodemographic characteristics of the Latino population, including educational attainment, poverty, immigration, family income, family size, family type, and language status is provided. The steady increase of this very youthful population makes it imperative that it receive an education that will provide it with the skills to make it a productive citizenry.


The Box and Block Test (BBT) is a post-stroke assessment that measures unilateral gross manual dexterity. Commonly used by doctors, nurses and rehabilitation therapists to evaluate rehabilitation progress, the test administration however is time consuming and labor intensive. Appointments need to be scheduled for patients to visit hospital clinics or the therapists to perform at-home visits. We present the Digital Box and Block Test (DBBT) that enables deployment in residential spaces. The system automatically recognizes the two sides of the box, blocks inside of the boxes, and then scores the results that can be sent to the doctors' office remotely. The system also provides additional information such as the hand movement, speeds and locations for the clinicians to perform further outcome assessments of the patients. In this paper, we discuss the role of the technology, how it improves the current practice, and describe the system implementation and future directions.


Using "Shanghai No.4" and "Dongcun Jiaopei" as donor materials,variants with improved heat tolerance were obtained through treating haploid stem apexes with pingyangmycin and then culturing survived stem apexes with stress of higher temperature.After chromosome doubling and electric conductivity measuring,9 variants with higher stability of cell membrane to heat stress than the original varieties were selected.


Introduction The high activity of supported Au nanoparticles for the catalytic CO oxidation has been described extensively and discussed in terms of the role of the gold particle size and that of the atoms at the periphery of the interface between Au and supports [1-3]. The interaction of a metal particle supported on an oxide was considered by Frost who proposed that the oxygen vacancy concentration in the metal oxide increases at the metal/metal oxide interfacial sites due to the junction effect [4]. However, there is no direct evidence showing that the periphery of the interface between metal and support is the locus of active sites for the CO oxidation reaction in the Au/CeO2 system. This work focuses on investigating the role of the interface in CO oxidation, using a multilayered structure of Au/CeO2 (also called Au/CeO2 nanotowers). This structure allows one to control quantitatively the following three variables: the total surface area of Au/CeO2, the interfacial length, and the thickness of each Au layer. Zuburtikudis et al. have shown that such a nanotower structure with the edge dimension in nanometer scale reproduced the size effects observed with conventional nanoscale particles [5]. A strong dependence on interface length for CO oxidation on Ir/Al2O3 nanotowers was observed by Chaplin using this approach [6]. In this work, such a structure was adapted to Au/CeO2 catalyst, which allows the three variables to change independently and, thus, enables the evaluation of the role of each variable separately.


This paper deals with optimum design of convective longitudinal fins of a trapezoidal profile.

They are presented in graphical forms in order to aid thermal designers


Abstract In this communication, we report the superior role of 1,3-dimethyl-2-imidazolidinone (DMI) as a solvent for aromatic Finkelstein iodination (AFI), the conversion of aryl bromides to aryl iodides. DMI accelerates the reaction rate and affords product(s) that could not be prepared using previous methods. Our findings for AFI avoid the use of toxic solvents such as N,N-dimethylformamide and hexamethylphosphoramide. GRAPHICAL ABSTRACT


Based on the related theoretical models about the gatekeepers in network communication,this paper proposes a model of the gatekeepers'combined strength in network communication and makes a tentative ananysis of the principle of network gatekeeping and the gatekeepers'media literacy.


The synthesis and complete characterization of the family of tetra(amine)bisphosphine ligands (o-NMe2C6H4)2P-(X)-P(o-NMe2C6H4)2, where X = CH2 (dmapm), (CH2)2 (dmape), and (dmapcp), are described. Crystal structure data are compared with known, analogous bisphosphines containing o-pyridyl or phenyl substituents in place of the o-dimethylanilinyl groups. Several short, intramolecular C-H···N distances in the anilinyl derivatives may represent the presence of weak hydrogen bonds. Key words: phosphine, amine, polydentate, hydrogen-bonding to N atoms.


Winder and Carmondy (2002) provided an enlightening discussion on the dermatological problems related to cement. Although they mention that this substance is a carcinogen, due to its common use in construction and the building environment, I feel that its hazard as a potential cancer agent needs further discussion. As noted by the authors', it has become recognized that cement is a potential carcinogen (Smailyte et al ., 2004). I would suggest that cement is potentially an important cancer hazard due to its commonality of use. There are a large number of occupations (Rafnsson et al ., 1997) besides cement workers that have frequent contact with this agent. Likely chemicals that contribute to cement's carcinogenicity are chromium (VI) and chromium (III) (Smailyte et al ., 2004). Cancer sites that have been reported to be associated with cement include skin, bladder, stomach, lung (Smailyte et al ., 2004) and prostate (Knutsson et al ., 2000). There are likely other sites that have not been recognized or substantiated (e.g., colorectal) (Smailyte et al ., 2004). However, it is agreed that skin problems represent the highest number of health problems associated with the occupational environment, but are considered generally less life threatening than cancer.


Prostate cancer is the second most common malignancy in men, after skin cancer, and the second most common cause of cancer death in men over age 60 years, after lung cancer. This year, ∼198 100 new cases of prostate cancer will be diagnosed in the US, and an estimated 31 500 men will die of prostate cancer (1). Five-year survival is close to 100% when the disease is diagnosed and treated with definitive local therapy while it is still organ-confined, but in approximately one-third of men diagnosed with clinically localized disease, the disease has spread beyond the confines of the prostate at the time of surgery (2)(3).

The Food and Drug Administration approved a serum test for prostate-specific antigen (PSA) in the 1980s. With an upper reference limit in serum of 4 μg/L, 67–80% of prostate cancers can be detected, for a positive predictive value of 24% (4)(5). Combining the serum PSA test with a digital rectal examination can improve the positive predictive value (3)(6)(7). Despite the availability of the PSA test and the moderately high compliance with routine testing recommendations, ∼20–30% of prostate cancers are missed by the current early detection protocols. The identification of more accurate serum markers for prostate cancer could improve the current clinical capabilities for cancer detection and may reduce cancer mortality.

Proteomics, the large-scale comparison of protein expression patterns, can be used to identify proteins that are associated with disease states such as cancer. These studies have been enhanced by the development of powerful and sensitive new methods, such as matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF). In this technique, proteins are adsorbed to a solid matrix, desorbed with a pulsed laser beam to produce gas-phase …

This paper uses the general economic model to explain the theoretical base of preferential policies, then talks about the policy object-the measurment problem about the beneficial spillover effect of transnational corporation.The articl probes into the practice of preferential policy around the measurement problem and puts forward the sub optimal strategy of solving the measurement problem about spillover effect game theory.


Background Herpes zoster (HZ), a disease of the immunocompromised and the elderly, can also occur in healthy children. Case series and surveillance studies have consistently identified early childhood varicella (VZV) infection (age Case Description We present a case of HZ in a 16-year-old immunocompetent male whose primary VZV infection occurred when he was 8 years old. His course was complicated by an unusual rash involving > 1 dermatome, viral meningitis (confirmed by PCR), and renal insufficiency following a 3-day course of acyclovir. Implications HZ can occur in healthy children of all ages, including those whose primary VZV infection occurs at a later age. Even short courses of acyclovir therapy in children with normal renal function may lead to acute renal failure. Physicians should carefully assess the benefits and risks of acyclovir for HZ in healthy children. If it is initiated, renal function should be monitored closely.


Hyperkalemia is associated with an increased risk of mortality and is a common complication in patients with chronic kidney disease (CKD). Despite the prevalence of hyperkalemia, current real-world data suggest that serum potassium levels are not effectively managed in clinical practice. The potential benefit of potassium binders in reducing the risk of death has not been thoroughly investigated. Therefore, this retrospective cohort study aimed to investigate the potential impact of potassium binders on mortality risk in patients with CKD by analyzing electronic medical records. The study included 1689 patients with CKD and hyperkalemia (serum potassium level > 5.0 mEq/L), who visited Kawasaki Medical School Hospital between January 2014 and December 2018. The patients were divided into two groups: those without CPS (calcium polystyrene sulphonate) treatment (CPS_OFF) and those with CPS treatment (CPS_ON). The results showed that the incidence of death was significantly higher in the CPS_OFF group than in the CPS_ON group (22.3% vs. 19.6%, p < 0.001). After propensity score matching, the CPS_ON group had a higher survival rate than the CPS_OFF group (log-rank test, p = 0.020). These results suggest that potassium binders may reduce the risk of death in patients with CKD and hyperkalemia. We hope that the results of this cohort study will be confirmed in future RCTs.

The metabolic activity of the polyphosphoinositides in unstimulated human platelets was studied by 1) short-term labelling with 32P-Pi, 2) by replacement of PP. from pre-labelled platelets with unlabelled phosphate and 3) by depriving the cells of metabolic ATP. Under short-term labelling conditions, the 4- and 5-phosphates of phosphatidylinositol-4-phosphate (PIP2) and phosphatidylinositol 4,5-bisphosphate (PIP2) had the same specific radioactivity as the γ-phosphate of metabolic ATP. The specific radioactivity of the 1-phosphates of phosphatidylinositol, PIP and PIP2 was similar but only 4-13 % as compared to the γ phosphate of ATP. When 32P-Pi. pre-labelled platelets were incubated with up to 25 mA of unlabelled phosphate, the displacement of the P-label from PIP, PIP2 and metabolic ATP followed similar kinetics. Inhibition of ATP regeneration in 32P-Pi pre-labelled platelets resulted in a rapid fall in metabolic ATP with much slower fall in 32P-PIP. 32P-PIP increased initially and decreased thereafter in parallel with PIP2. However, ATP turnover was not abolished, as indicated by the marked (25 % of the control) incorporation of extracellular 32P-Pi. into PIP and PIP2 in metabolically inhibited platelets. This low phosphate turnover may explain the relative resistance of PIP and PIP2 to metabolic inhibition. We conclude that PIP and PIP2 are present as a single metabolic pool in human platelets. Turnover of the 4- and 5-phosphates of PIP and PIP2 in unstimulated platelets is as rapid as that of the γ- Phosphate of metabolic ATP, and accounts for about 7 % of basal ATP consumption.


The modern standards and algorithms of antimicrobial therapy, that ensure a high level of the treatment's quality and prevention of the most infectious-inflammatory diseases, provide wide using of chemotherapeutic agents. However, the modern medicines do not always have satisfactory chemotherapeutic and pharmacological properties; this fact is most often associated with the resistance of microorganisms to them. That is why the creation of the new chemotherapeutic drugs by natural antibiotics' chemical and microbiological modification, the chemical synthesis of the new substances among the various classes of organic compounds is a topical problem.

It is not known how much reduction in weight is caused by an increased frequency of breakfasts including more protein, or whether such a practice suppresses intake by subconscious post-ingestional effects or intentional reduction in frequency of consumption of other foods. Participants with low frequency of what they believed to be higher protein breakfasts (HPBs) were asked to increase HPB frequency for 4 weeks and then to decrease HPB frequency for the subsequent 4 weeks, while participants with high HPB frequency were asked to follow the opposite sequence. Participants recorded daily if they ate an HPB that morning and had eaten perceived energy-dense foods (EDFs) and/or taken exercise at any time. Greater amounts of fat and weight were lost with perceived HPBs increase than decrease. One more perceived HPB per week for 4 weeks lowered body fat by a mean of 0.05 % (95% CLs: 0.15, -0.04), and weight by 97 g (171, 24). One less perceived EDF occasion a week reduced fat 0.04 % (0.11, -0.03) and weight 81 g (134, 27). These findings show that a sustained change in the frequency of a culturally specified habit can influence weight by a measured amount. This effect could come from the delayed gluconeogenesis from dietary protein amino acids but beliefs about protein at breakfast and energy-dense foods may also play a part.


Since the beginning of the COVID-19 outbreak, the scientific community has been making efforts in several areas, either by seeking vaccines or improving the early diagnosis of the disease to contribute to the fight against the SARS-CoV-2 virus. The use of X-ray imaging exams becomes an ally in early diagnosis and has been the subject of research by the medical image processing and analysis community. Although the diagnosis of diseases by image is a consolidated research theme, the proposed approach aims to: a) apply state-of-the-art machine learning techniques in X-ray images for the COVID-19 diagnosis; b) identify COVID-19 features in imaging examination; c) to develop an Artificial Intelligence model to reduce the disease diagnosis time; in addition to demonstrating the potential of the Artificial Intelligence area as an incentive for the formation of critical mass and encouraging research in machine learning and processing and analysis of medical images in the State of Mato Grosso, in Brazil. Initial results were obtained from experiments carried out with the SVM (Support Vector Machine) classifier, induced on a publicly available image dataset from Kaggle repository. Six attributes suggested by Haralick, calculated on the gray level co-occurrence matrix, were used to represent the images. The prediction model was able to achieve 82.5% accuracy in recognizing the disease. The next stage of the studies includes the study of deep learning models.


LetT be a rooted and weighted tree, where the weight of any node is equal to the sum of the weights of its children. The popular Treemap algorithm visualizes such a tree as a hierarchical partition of a square into rectangles, where the area of the rectangle corresponding to any node inT is equal to the weight of that node. The aspect ratio of the rectangles in such a rectangular partition necessarily depends on the weights and can become arbitrarily high. We introduce a new hierarchical partition scheme, called a polygonal partition, which uses convex polygons rather than just rectangles. We present two methods for constructing polygonal partitions, both having guarantees on the worst-case aspect ratio of the con- structed polygons; in particular, both methods guarantee a bound on the aspect ratio that is independent of the weights of the nodes. We also consider rectangular partitions with slack, where the areas of the rectangles may dier slightly from the weights of the corresponding nodes. We show that this makes it possible to obtain partitions with constant aspect ratio. This result generalizes to hyper- rectangular partitions in R d . We use these partitions with slack for embedding ultrametrics into d-dimensional Euclidean space: we give a polylog()-approx


An expansion, or ballooning, of a section of the aorta within your chest (thorax) that slowly degenerates. The aorta, the body's main blood vessel, starts at your heart and extends all the way to your pelvis, where it branches toward your legs. The larger the aneurysm, the higher the risk it may rupture, leading to damage of the aortic wall and bleeding that could cause death.


US household transportation surveys typically have limited coverage of and responses from people of color (POC), which may lead to inaccurate estimation of POC transportation access and behavior. We recast this technocratic understanding of representativeness as a problem of "racial misrecognition" in which racial group difference is obscured yet foundational for distributive transportation inequities and unsustainability. We linked 2008–2012 population and housing data to an apparent stratified random sample of 6107 household responses to the 2011 Oregon Household Activity Survey (OHAS) in a "sustainability capital": the Portland, Oregon metropolitan area. We detailed how the 2011 OHAS consistently overrepresented White households and underrepresented Latinx/Nonwhite households in aggregate and at the tract-level. We conducted tract-level spatial pattern and bivariate correlation analyses of our key variables of interest. As expected, our subsequent tract-level spatial error regression analysis demonstrated that the percent of Latinx/Nonwhite householders had a significant negative association with 2011 OHAS household response rates, net of other statistical controls. Further analyses revealed that the majority of the ten "typical" tracts that best represented the spatial error regression results and racial misrecognition in the OHAS exhibited historical and contemporary patterns of racial exclusion and socially unsustainable development in our study area.


BACKGROUND
In order to study the influence of plant growth-promoting bacteria (PGPB) belonging to Streptomyces sp., Paenibacillus sp., and Hymenobacter sp. on fixed oil content of flaxseed and black cumin, 2-year field experiments were conducted. PGPB was applied during seedtime of plants. The extraction of oil from seeds was performed using supercritical CO2 .

RESULTS
The addition of PGPB significantly increases the content of C18:1 (from 16.06 ± 0.03% to 16.97 ± 0.03%) and C18:3 (from 42.97 ± 0.2% to 45.42 ± 0.5%) in flaxseed oil and C18:2 (from 52.68 ± 0.50% to 57.11 ± 0.40%) and C20:2 (from 4.34 ± 0.02% to 4.54 ± 0.03%) in black cumin seed oil. The contents of total polyphenols, flavonoids, and carotenoids, as well as antioxidant activity measured by ferric-reducing ability of plasma assay, were found to be greater in the oil from the seeds of plants treated with the PGPB, compared with the respective non-treated samples.

CONCLUSION
The use of PGPB enhances plant nutritive properties; these represent a great source for obtaining valuable functional food ingredients. © 2017 Society of Chemical Industry.

COMPARISON OF STIGMA TOWARDS DEPRESSIVE PERSONS AND SELF-STIGMA IN STUDENTS OF HELPING AND NONHELPING PROFESSIONS The aim of the research was to examine the differences in the attitudes towards depressive persons and the levels of self-stigma in the students of medical (nursing and medicine; N=101) and non-medical (social work and psychology; N=98) helping professions and the students of non-helping professions (education, speech pathology and social pedagogy; N=109). The covariance analysis determined that, in spite of rarer actual contact with depressive persons and a smaller number of courses teaching them about depression during the course of study, the students of social work and psychology had more positive attitudes towards depressive persons than the students of medicine and nursing. Apart from that, they were better in recognizing the symptoms of depression. Contrary to that, three groups did not differ with regard to perceived stigma, which was more expressed in comparison with the self-stigma. Additionally, the students of non-medical helping professions showed a more pronounced self-stigma than the students of medical helping professions. The students of psychology and social work, in comparison with the students of medicine and nursing, expressed a higher level of shame at the thought of suffering from depression, as well as the more expressed belief that they could not make a positive contribution to society if they suffered from depression.


The perfluorocarbon Fluosol DA has been reported to increase the subjective echogenicity of infarcted myocardium. To investigate this phenomenon, two‐dimensional echocardiograms were recorded in 20 closed‐chest dogs before and 24,48,72, and 96 h following permanent coronary artery occlusion. Low‐dose Fluosol, 10ml/kg (LDF) (four dogs), high‐dose Fluosol, 25 ml/kg (HDF) (eight dogs), or lactated Ringers 25 ml/kg (LR) (eight dogs) was administered 48 h after occlusion. Left ventricular sections corresponding to the short‐axis echocardiographic examination plane were stained with nitroblue tetrazolium 48 h after Fluosol administration. Short‐axis echocardiographic studies were evaluated by two blinded observers who found no consistent increase in the echogenicity of the infarcted area in any group. Videodensitometry of the infarcted area, normalized to the average value of two remote areas, confirmed mean post‐Fluosol increases of 66% in LR dogs, 65% in LDF dogs, and 107% in HDF animals (p < 0.001 for all dogs; all intergroup comparisons NS). The increase in videodensity observed in all groups may have occurred as a consequence of volume administration, although changes in infarct intensity occurring over time cannot be excluded.


In this paper, an analytical modelling of power loss distribution has been addressed for different traction current source inverters. After having described the topologies and modulation strategies, modelling of losses for each semiconductor device composing the inverters is provided. Then, the theoretical study has been validated through extensive simulations performed on a 35kW permanent magnet synchronous motor drive fed by the considered current source inverter topologies. Furthermore, the power loss and overall efficiency of current source inverter-based motor drives have been compared to a traditional two-level voltage source inverter fed motor drive including an output LC filter. Results underline pros and cons of using current source inverter topologies based on wide bandgap semiconductor devices.


Video-based photogrammetry combined with a laser sheet is used to measure the section profiles of a parafoil model of aspect ratio 2.5 during tethered testing in a low-speed tunnel. Surface contours of parafoils during operation in a wind tunnel are obtained. Leading-edge collapse, high angle of attack flight, and oscillatory yaw are studied. Force measurements, including CL and CD for the parafoil, are also obtained for the conditions studied.


ABSTRACT This study examined strategy-related factors (Business strategy, Information technology, Quality of management accounting skills, and Organisational culture) moderating the fit between management accounting practice (MAP) sophistication and organisational effectiveness from the perspective of the Global Management Accounting Principles (GMAP). The GMAP was jointly developed and endorsed by The American Institute of Certified Professional Accountants (AICPA) and The Chartered Institute of Management Accountants (CIMA) to support Chief Executives, Boards of Directors, Chief Finance Officers and Management Accounting Practitioners to benchmark and improve management accounting practices. The study focused on 131 firms across various industries in Nigeria. Analysis of data collected through questionnaire revealed that the two high-ranking factors responsible for the degree of MAP sophistication are business strategy and quality of information technology. It was observed that although business strategy and information technology significantly moderate the relationship between MAP sophistication and Organisational effectiveness, business strategy exerts greater influence. The finding that business strategy strongly moderates the relationship between MAP sophistication and organisational effectiveness connotes that forward-thinking business entities would leverage on the strategy-formulation and strategy-implementation capabilities of contemporary management accounting techniques to drive performance and achieve business imperatives.


matologic remission. Ten weeks after starting dasatinib treatment, the patient was admitted to our hospital with abdominal pain and rectal bleeding. Laboratory results were as follows: hemoglobin 10.3 g/dl, white blood cells 6 ! 10 9 /l, platelets 185 ! 10 9 /l, prothrombin time 14 s, active partial thromboplastin time 33.3 s, international normalized ratio 1.25. Stool examination was negative for parasites and other pathogenic bacteria. Sigmoidoscopic examination was performed with only rectal osmotic laxative without entire colon cleansing. There was no active bleeding, but multiple milimetric nodular hyperemic lesions on the mucosa were seen in the left side of colon and biopsies were taken during sigmoidoscopic examination ( fig. 1 ). Histopathological findings revealed nonspecific active colitis ( fig. 2 ). The patient was hospitalized and dasatinib treatment was stopped. No bleeding was observed during follow-up and colonoscopy was performed 2 weeks later. Endoscopic and histopathological findings were all normal, and dasatinib treatment was restarted. The patient was admitted to the hospital again with hematochezia 1 month after dasatinib administration. Colonoscopy repeated and findings were consistent with acute colitis. Again dasatinib treatment was stopped and patient was observed for 5 days in hospital without any bleeding. Repeated colonoscopy was normal after dasatinib treatment discontinuation. Nilotinib (400 mg/day) was started as an alternative to dasatinib for CML treatment. The patient remained in hematological remission during 6 months of follow-up without any further complication. Dasatinib is a second-line tyrosine kinase inhibitor used in imatinib resistant or intolerant chronic myeloid leukemia (CML) and Philadelphia chromosome-positive acute lymphoblastic leukemia. It inhibits several critical oncogenic proteins, including bcr-abl, Src familial kinase, Kit, platelet-derived growth factor receptor and ephrin A receptor kinase. Dasatinib, which binds both active and inactive conformation of bcr-abl oncoprotein, has greater potency than imatinib for both wild-type and mutant BCR-ABL, except the T315I mutation [1, 2] . Mild to moderate thrombocytopenia and neutropenia occurred in approximately 50% of patients, but it is generally well tolerated. Other side effects are diarrhea, headache, weakness, pleural effusion, nausea and peripheral edema. Gastrointestinal bleeding may occur in up to 7% of patients using dasatinib [3] . Current literature suggests severe rectal bleeding due to acute colitis during dasatinib treatment has been reported only in 1 pediatric Philadelphia chromosome-positive acute lymphoblastic leukemia patient [4] . Here, we report an adult case with acute colitis with severe rectal bleeding after dasatinib use. This complication has not been previously reported in an adult population. A 55-year-old patient had been diagnosed with blastic phase of CML 2 years ago. After remission induction treatment including cytosine arabinoside, idarubicin and imatinib (400 mg/day), maintenance treatment was continued with imatinib. During the follow-up, dasatinib (100 mg/day) was started because of disappearance of heReceived: December 14, 2009 Accepted after revision: January 28, 2010 Published online: April 8, 2010


This is an edited transcript of remarks presented at a Symposium on South Dakota v. Dole at the University of South Dakota School of Law in January 2007. Topics discussed include the proper demarcation of powers between the federal and state governments, the value of federalism, conditional federal spending, and the doctrine set out in the U.S. Supreme Court's 1987 decision in South Dakota v. Dole.


tionist one. What I find poignant in this honest monograph is the author's evident struggle to reconcile finding no facts to support the currently popular idea that human populations (whether initially profligate or later growing too dense for their resources to sustain without damage) in the Pacific islands inevitably decreased environmental diversity through inappropriate farming methods, over-hunting of birds, and unrestrained marine resource procurement: ''That resource depression and extinctions were not more visible archaeologically may signal that human populations, albeit quite low in number, lived in a sustainable manner—a unique situation amongst many Pacific islands studied thus far'' (p. 128). Weisler's solution to this self-inflicted dilemma, of having documented an actual case of Pacific islanders making a ''sustainable living'' for about two thousand years and counting, is the typical inductivist call for more data, using a ''comparative approach'' wherein ''we may come to understand the breadth of atoll adaptations— technological, economic and social'' (p. 128). With On the Margins as an example of the attention to detail in data collection and presentation required, a more economic approach would be for Pacific archaeologists to re-examine their alreadycollected ''data'' on allegedly humancaused environmental changes. The Marshallese case (and here I refer to this and other publications of Weisler's and others cited in the text) shows there are more realistic models of prehistoric human behavior than those imagined by Steadman (1995 and others), and certainly warrants a call for incorporating physical causal factors, such as habitat fragmentation (Burkey 1995) and climatic and sea-level oscillations during the late Holocene (Nunn 1998; Dickinson 2001; Hunter-Anderson 2002) into our explanatory models.


One of the important factors in supporting the sustainability of an architectural design is the ability to adapt to the environment. This adaptation can be observed, among others, from the accommodative level obtained from a building design to the needs of the community that uses the design. One form of design that is considered to accommodate the needs of the user community is the design of a floating system used by fishing communities. This paper wants to explore the adaptability of the floating system design which is judged by its ability to accommodate the dynamics of the wet environment and the needs of the fishing community. The research method is descriptive and logically explains the causal relationship between the design of the floating system building and the environmental and socio-cultural aspects of the community. Observations show 2 things: a) the legged building system (pit foundation and 2 meter stilt building) is highly adaptive to wetland conditions with tidal characteristics of water at the mouth of the river; b) architectural design of residential units which are about 4 meters apart, allowing the development of residential units into 4 sides, to accommodate the increase in daily activities of fishing communities so that community productivity increases. The conclusion of the study shows that the floating system is very flexible and adaptive to the dynamics of the environment and people's lives (socio-cultural and economic aspects).


CT-scan is used to analyze the structures of specific body parts, mainly to confirm the diagnosis of non-hemorrhagic stroke. Stroke is a neurological deficit that occurs suddenly and caused by the interruption of blood flow to the brain. The symptoms are corresponding to the location of the stroke. This study was aimed to obtain the CT-scan examination of non-haemorrhagic stroke patients. This was a retrospective descriptive study using secondary data such as request letter and data of head CT-scan performed from August 2015 to August 2016. The results showed that there were 89 cases of non-hemorrhagic stroke. The majority were males (60 patients; 67%), elderly ≥65 years old (27 patients; 30%), and location of lesion in the right hemisphere (38 patients; 43%). Conclusion: In this study most patients diagnosed as non-hemorrhagic stroke with CT-scan were males, over 65 years old, and location of lesion in right hemisphere.

This article provides a new analytical method based on a fixed point approach to estimate the impact of active queue management schemes on the quality of service of voice over IP applications. The results obtained by the proposed method were validated using discrete event simulation techniques. In all the studied cases it was observed a great deal of agreement between the analytical results and the results obtained through simulation. The theoretical predictions, as well as the presented empiric evidences demonstrate that the use of active queue management offers a better quality of service than the traditionally queue control mechanisms used in Internet.


made to our current understanding of the teaching and learning of jazz improvisation. The past two decades have seen a dramatic increase in the institutional acceptance of the jazz art form and an equally dramatic proliferation of instructional materials promising to nurture the development of the improvisational skills which are its essence. To what extent, then, has doctoral research in jazz pedagogy paralleled these noteworthy developments? How has scholarly research contributed to the refinement of pedagogical materials, to their effective use, or enhanced the preparedness of music educators to teach improvisation? How has our understanding of the distinct nature of this idiom evolved since Tanglewood Symposium endorsements of its unique value? With these questions in mind, an examination of recent research literature was undertaken.


Catch like property is a force enhancement produced in the muscle when a briefhigh frequency burst of pulses is added to a low frequency electrical stimulation train. In functional electrical stimulation(FES)low frequency stimulation of approxi‑ mately 20 Hz has primarily been used to reduce muscle fatigue. In the present studythe effects of catch like property on muscle fatigue were analyzed using intermittent electri‑ cal stimulation. The results showed that compared to conventional low frequency stimulation low frequency stimulation taking advantage of the catch like property significantly increased the maximum muscle force and workload and decreased muscle fatigue. The results of the present study suggest that catch like property is useful in clinical administration of FES.


In this paper a new initial value prediction of curve-fitting algorithm is presented for extracting the parameters of the single-diode model. Before extracting the parameters of the single-diode model of Photovoltaic (PV) modules, a reform of the equation of the single-diode model has been presented for improving the accuracy of the Single-diode model. And the biggest advantage of the algorithm is the prediction of initial value where Newton-Raphson method utilized to seek the root of initial value objective function. Also, Gauss-Newton iteration method have been applied to seek the optimal value of the algorithm—the least square nonlinear multiple regression. Test on two classic case studies and operational PV cells and modules, the proposed algorithm exhibits substantial improvement in terms of fitting accuracy, where the root-mean-square error is lower than other methods, and reliabilities for practical applications including different types and materials. With these, the proposed method is envisaged to be valuable for practical applications, in which accuracy of the single-diode model is of prime concern.


We compute the random coding error exponent for memoryless flat fading channels with ideal channel state information (CSI) and inputs drawn from a discrete alphabet. The signal sets we consider here are standard signal constellations commonly used in digital coded modulation. In addition, estimates of the code lengths required to achieve a certain error probability are determined and compared to those required for the AWGN channel. Finally, the effect of receiver diversity combining on improving communications reliability over the fading channel is considered. The results we obtain here shed light on the achievable performance over the fading channel with coded modulation.


When parents and children care about each other's utility, increases in parental income need not always lead to decreases in child labor. Adults raised in poor families make altruistic transfers to their elderly parents, which the parents take as repayment for income lost when their children were young and spent some time in school instead of work. There is some sufficiently high level of parental income at which children cease to believe that parents need a transfer, whereas parents still would like repayment, so both transfers and the hours of extra education that the transfers made possible cease. Child labor rises.


After the General Data Protection Regulation (GDPR) entered into force, the topic of overseas transfer of personal data for purposes of storage and processing has gained visibility and prominence in both the privacy impact assessments and the informed consent forms issued by EEA based organisations. Related compliance issues have been exacerbated by a 2020 ruling of the European Court of Justice, which upheld the adoption by US based providers of Standard Contract Clauses to safeguard the data subjects' rights of EEA citizens whose personal data is stored or processed on their platforms. A little explored set of privacy issues materializes when data flows take the opposite direction: i.e. gathered/stored outside and shared/processed inside the EEA space. This paper takes such perspective to examine, in a comparative fashion, the similarities and distinctions between the GDPR provisions and the privacy regimes of China, US and UK (after Brexit), each of them undertaking a process of transformation, and convergence towards GDPR, although with different approaches and pathways. The topic can be of interest for research or service teams engaged in multi-country data gathering, a trend one may expect to grow in the future.


If $\Lambda $ is a measure space, $u:\Lambda ^{m}\rightarrow \Bbb{R}$ is a given function and $N\geq m,$ the function $U(x_{1},...,x_{N})=\left( \begin{array}{l} N \\ m \end{array} \right) ^{-1}\sum_{1\leq i_{1}<\cdots <i_{m}\leq N}u(x_{i_{1}},...,x_{i_{m}}) $ is called the generalized $N$-mean with kernel $u,$ a terminology borrowed from $U$-statistics. Physical potentials for systems of particles are also defined by generalized means.
This paper investigates whether various measure-theoretic concepts for generalized $N$-means are equivalent to the analogous concepts for their kernels: a.e. convergence of sequences, measurability, essential boundedness and integrability with respect to absolutely continuous probability measures. The answer is often, but not always, positive. This information is crucial in some problems addressing the existence of generalized means satisfying given conditions, such as the classical Inverse Problem of statistical physics (in the canonical ensemble).


The aggregation structure, the molecule chain morphology and secondary structural parameters of SEB were investigated with modern structural analyzing techniques, such as X-ray diffraction, scan electron microscopy, atomic force microscopy and fourier transform infrared spectrum. Crystallization was found in SEB with the crystallinity of 37.8%. The conformation of the conglomerated SEB molecules was sheet and plate. In dilute solution, the length, width and height of the SEB molecular chain were 1500 nm, 20~40 nm and 0.6nm, respectively. It was also found that the secondary structure of SEB was mainly of β-sheets.


The effect of temperature on the sporogonic cycle of Plasmodium berghei was studied in two experimental mosquito vectors. Complete sporogonic development takes place in Anopheles quadrimaculatus at 16 to 21 C, and in A. stephensi at 16 to 24 C. The upper temperature limits for development appear to be the lowest reported for any plasmodia. The sporogonic development of P. berghei is apparently adapted to the narrow temperature range which is found in the microclimate of its natural vector. High temperatures have a more rapidly damaging effect on the early than on the late stages of sporogony. Mosquitoes exposed to 28 C for as short a time as 4 hr following their infective blood meal fail to develop sporozoites. If this high temperature treatment is withheld until the parasite completes the early stages of sporogonic development at a favorable temperature, exposure to at least 3 days of 28 C is necessary to induce visible damage. The mode of action of high temperature damage is unknown at present. Ever since the discovery of the rodent malarial parasite, Plasmodium berghei, by Vincke and Lips (1948), laboratory investigations involving the sporogonic stages of development of the parasite have been impeded by the inability to find a suitable experimental vector. Recent work (Yoeli, Most, and Bone, 1964; Vanderberg and Yoeli, 1965) has shown that the parasite can be readily transmitted by several species of anophelines if the infected mosquitoes are maintained at a temperature of about 21 C. This is the approximate daytime temperature that the natural vector, Anopheles dureni, is subjected to in its microclimate within the forest galleries of the Congo during the transmission season. Previous experiments conducted in our laboratory in which mosquitoes were kept at 28 C only rarely resulted in successful cyclical development. P. berghei, apparently, is unusual among the malarial parasites in that its sporogonic stages develop optimally at relatively low temperatures. After our initial success at cyclical transmission of P. berghei by experimentally infected mosquitoes, we thought it useful to examine in more critical detail the effects that Received for publication 1 December 1965. *This work, contribution number 36 from the Army Research Program on Malaria, was carried out under the sponsorship of the Commission on Malaria, Armed Forces Epidemiological Board, and supported in part by the U.

ETV6/TEL1 (hereinafter referred to as TEL1) is an ets family transcription factor that is frequently involved in chromosomal translocations associated with leukaemia, including t(12:21) which generates the TEL-AML1 fusion gene, the most common genetic abnormality in childhood cancer. The role of TEL1 in normal haemopoiesis has been extensively studied in the mouse where knock-out studies have indicated that TEL1 is not required for development of primitive (ie yolk sac-derived) haemopoiesis. TEL1-knockout mice die at day E10.5 due to a defect in angiogenesis precluding direct analysis of the definitive (ie intraembryonically-derived) haematopoietic system. Analysis of chimaeric mice generated using TEL1−/− ES cells suggest that TEL1 is not required for generation of the definitive haemopoietic system during ontogeny but is required for HSC survival perinatally at bone marrow stages. Conditional knockout studies have subsequently identified a role for TEL1 in the survival of adult bone marrow-derived HSC. We now report the analysis of TEL1 function in amphibian ( Xenopus ) embryos where haemopoietic development can be studied even in embryos with defective angiogenesis. We characterised the TEL1 expression pattern and knocked down its function using antisense morpholino oligonucleotide injection. Consistent with the mouse knockout, specification of the primitive haemopoietic system was unaffected, however a defect in maturation of primitive erythroid cells, not previously reported in the mouse, was also apparent. We next analysed the development of the definitive haemopoietic system, thought to arise as clusters of HSCs in the floor of the dorsal aorta. But, no clusters of HSCs were found. Formation of the dorsal aorta however, proceeded normally, indicating that TEL1 controls the decision between the arterial and HSC programmes. Given, the critical role for TEL1 in the development of HSC indicated by these studies, a temporal analysis of emergence of intraembryonic HSC in TEL-deficient mice may be warranted.


Multiple myeloma (MM) is an incurable plasma cell disorder representing 10% of all hematologic malignancies. Cancer is a known risk factor for venous thromboembolism (VTE). Patients with MM are at a particularly high risk of developing VTE owing to patient characteristics (e.g. previous history of VTE), disease characteristics, and treatment characteristics including use of the immunomodulatory agents (IMIDs). Unfortunately, standard criteria to identify the patients most at risk for developing VTE in MM while receiving IMIDs are unknown. We sought to assess the incidence of VTE and its associated risk factors in MM patients receiving IMID therapy. A retrospective cohort study including 1680 consecutive patients with multiple myeloma treated at our centre between January 01, 1995 and January 26, 2016 was conducted. The annual incidence of VTE on immunomodulatory agents including thalidomide, lenalidomide, and pomalidomide was derived. Univariate incidence ratio analyses of VTE for different risk factors was performed including: previous history of VTE, concomitant use of dexamethasone, and ≥/ A total of 309 MM patients treated with an immunomodulatory agent were identified. Nineteen patients were excluded (incomplete data, lost to follow). Of the remaining 290 patients, the mean age was 67.9 and 42.4% were female. Twenty-seven VTE events were recorded. The overall risk ratio was 6.1 for the development of VTE. Patients with a personal history of VTE had an increased risk of suffering a VTE while on IMID therapy (IRR 5.4; CI, 1.9-13.6). The time from the initiation of the IMID therapy (less than 6 months) also increased the risk of developing a VTE (IRR 51.7; CI,19.4-160.1). The concomitant use of dexamethasone was not associated with a statistically significant increased risk (IRR 1.7; CI, 0.3-69.5). Incidence risk ratios for these risk factors are depicted in Table 1. Our results suggest that a personal history of VTE and the time from the initiation of the IMID (less than 6 months) are associated with an increased risk of VTE in MM patients receiving IMID therapy. This may be helpful in determining which multiple myeloma patients treated with an IMID agent warrant more aggressive thromboprophylaxis. Further prospective studies are needed to determine the optimal agent, intensity, and duration of thromboprophylaxis in patients with MM on IMID therapy. Disclosures McCurdy:Celgene: Honoraria.


Introduction. The main disease that complicates HIV is Pneumocystis pneumonia. It often requires differential diagnosis with tuberculosis. Aim. The aim of the study was to conduct a comparative analysis of the clinical features and main indicators of iron metabolism in HIV infection with disseminated pulmonary tuberculosis and Pneumocystis pneumonia and to identify potential differential diagnostic markers of tuberculosis. Material and methods. The study included two groups of patients with HIV infection: 42 patients with disseminated pulmonary tuberculosis and 44 patients with Pneumocystis pneumonia. The clinical and laboratory data was carried out, the main indicators of iron metabolism were determined: iron concentration, hepcidin, ferritin. Statistical data processing was performed using the MedCalc 19.2.6 statistical software. Results and discussions. In the group of patients with Pneumocystis pneumonia, the proportion of patients with a severe condition is greater, the level of CD4-lymphocytes is significantly lower - 5 times less than in tuberculosis (p <0.001). Statistically significant differences between the groups were found for hepcidin and serum. The median for hepcidin is 1.4 times higher in group 1 than in group 2 (p <0.001), for serum - 1.5 times less in group 1 than in group 2 (р<0,001). In patients with HIV and pulmonary dissemination, a higher probability of tuberculosis was revealed with hepcidin more than 13810 pg/ml (sensitivity 80.95%, specificity 75%, ROC AUC 0.854) and with an iron concentration less than 10 μmol / L (sensitivity 85.7%, specificity 59.1%, ROC AUC 0.733). Conclusion. When examining patients with HIV infection and pulmonary dissemination syndrome who have a common anamnesis, clinical and radiological, laboratory data and a high degree of suspicion of tuberculosis, it was established by the analysis of ROC curves that the peptide hormone hepcidin has the greatest practical value for its further comprehensive study as a potential and a promising marker for the diagnosis of tuberculosis.


A method for computing (approximate) cost-of-living index numbers for arbitrary reference income levels is presented. It combines the use of fairly disaggregated data with a relatively modest use of econometric methods. The basis ingredients are (1) a series of chained Tornqvist price index numbers relating to per capital total expenditure, (2) price index numbers for the commodities distinguished, and (3) the income parameters of a differential demand system. This method attains second order precision and is equivalent to a full econometric method based on a translog utility function. The method is demonstrated on Netherlands data for 1952-81.

In this work we present a new approach to molecules on Goldberg's local Hardy spaces h(R), 0 < p ≤ 1, assuming an appropriate cancellation condition. As applications, we prove a version of Hardy's inequality and improved continuity results for inhomogeneous Calderón-Zygmund operators on these spaces.


Common carp (Cyprinus carpio) are a non-native fish in the United States. Due to their prolific nature, they may have detrimental effects on fish and waterfowl communities, including those of Nebraska Sandhill lakes. Information regarding population structure, age, and growth of common carp in Nebraska Sandhill lakes is lacking. We examined adult common carp populations from Marsh and Pelican lakes on the Valentine National Wildlife Refuge. We described size and age structure, growth, and recruitment patterns for these two populations. Age-frequency histograms revealed consistent recruitment of common carp through age 7 in Marsh Lake but inconsistent recruitment in Pelican Lake. Common carp growth was initially faster in Pelican Lake than in Marsh Lake, likely because of a less dense carp population in Pelican Lake. Pelican Lake contains northern pike (Esox lucius) and largemouth bass (Micropterus salmoides), top-level piscivores, while Marsh Lake contains no predatory fish species. The absence of top-level piscivores preying on age-O common carp may have led to the denser population in Marsh Lake. Further research is recommended to understand fully the role of common carp in Sandhill lake communities.


A variety of glaciotectonic structueres are associated with a distinctive Middle- Wisconsin organic formation that is exposed at thirteen places along Michigan's Pine River. The carbonaceous material, with a 14C age of about 46,000 years BP, accumulated in an extensive, weakly geogenous, oligotrophic fen that was buried by sand before being deformed. Numerous faults and folds, the latter with observed amplitudes that may exceed 5 m, have a consistent sense of easterly structural vergence indicating glacial movement from the west. Gelogic relationships here and generally accepted regional chronology indicate that deformation was produced by Late Wisconsin ice that flowed from the Lake Michigan basin. This unequivocal marker bed provides detailed information on the topography, environment, and climate associated with an ice-free Middle-wisconsin landscape. Equally important and unprecedented for the area, it is an especially precise measure of multiple glaciotectonic effects upon an incompetent Pleistocene organic formation of considerable extent.

Constellation-to-ground coverage analysis is an important problem in practical satellite applications. The classical net point method is one of the most commonly used algorithms in resolving this problem, indicating that the computation efficiency significantly depends on the high-precision requirement. On this basis, an improved cell area-based method is proposed in this paper, in which a cell is used as the basic analytical unit. By calculating the accuracy area of a cell that is partly contained by the ground region or partly covered by the constellation, the accurate coverage area can be obtained accordingly. Experiments simulating different types of coverage problems are conducted, and the results reveal the correctness and high efficiency of the proposed analytical method.

Since sulfanilamide has come into general use, a number of reports have appeared indicating that jaundice 1 and hemolytic anemia 2 are toxic effects that may be encountered. One gains the impression from the majority of these reports that such complications are rarely encountered and that they are probably due to drug idiosyncrasy. Long and his associates 1g observed but 2 patients with jaundice (without hemolytic anemia) among 408 treated with sulfanilamide. In the material from the same clinic, Wood 2b noted that acute anemia developed in 21 of 522 persons to whom the drug was administered. He found the incidence of anemia to be 8.3 per cent in children as compared with 2.4 per cent in adults. He ascribed the anemia in the 21 cases to hemolysis, because of the abrupt appearance of jaundice and urobilinuria. In 8 additional instances a "slow" type of anemia was encountered, which was similar to that previously
