A Galactic gaseous halo formed through the interstellar disk-halo connection is simulated by means of a two-dimensional axisymmetric hydrodynamic code based upon the chimney model of the interstellar medium, a new version of the galactic fountain. Galactic rotation, heating processes by diffuse UV flux, and radiative cooling processes are taken into account. The resulting gaseous halo can be divided into three categories, i.e., wind-type halo, bound-type halo, and cooled-type halo. In this way, we try to reproduce the column densities of C IV, N V, O VI, and Si IV in the observed absorption lines of halo stars. Assuming that the radiatively cooled halo gas condenses into clouds due to thermal instabilities, we can calculate their distribution and ballistic motions in the Galactic gravitational field. These correspond to the high- and intermediate-velocity clouds observed at high Galactic latitudes. We find that a cooled-type halo with a gas temperature between 5 X 105 and 106 K and a density between 10-3 and 10-2 cm-3 at the disk-halo interface can reproduce the observational facts about our Galaxy. Supposing that the metal-absorption-line systems of QSOs arise from the halos of intervening galaxies formed by similar processes, we calculate features of the Ca II, Mg II, C IV, and Si IV absorption lines in various stages of galactic evolution. We conclude that C IV systems which are greater than 50 kpc in size correspond to the wind-type halo. On the other hand, Mg II and Ca II systems can only be detected in a very restricted region ( Metaxa, SMALL FAINT CLUSTERS IN THE LMC This is a short review of the main results of my Ph.D. thesis concerning some important problems on the dynamical properties of the LMC star clusters. The topic of this thesis was to find and study the dynamical paramters (tidal radius rt core radius rc concentration parameters log (rt/rc), and total mass M) for a large sample of small LMC clusters and to define their location in the parent galaxy. In particular we studies 70 small clusters (M < 104 solar mass) (Metaxa et al. 1988) which are located throughout the whole periphery of this galaxy. In addition, 93 small clusters (Kontizas et al. 1988) were detectd and cataloged in the central LMC area in order to establish if all small LMC cluster form one system. The examined sample represents 4% of the total LMC star-cluster population with diameters greater than 6 pc (Kontizas et al. 1990). The dynamical parameters were obtained by means of star counts performed on high-quality plates (I, J, R) taken with the 1.2-m Schmidt telescope for the remote clusters, whereas the central crowded LMC regions were examined on plates (U,B,V) taken with the 3.6-m ESO telescope. The main results are as follows: (1) An important criterion for classifying clusters is their density profile. Eighty percent of the studied LMC star clusters were found to have profiles which fit King (1966) radial-density distributions. The remaining 20% of the star clusters give profiles which are divided into categories which characterize each group of the discrepant clusters. What must be noticed is that one group of these clusters does not reach a flat central density, and at radii larger than the core radius will show various deviations from the theoretical profiles. This has been attributed to warm initial conditions. Another star-cluster group exhibits a ''bump'' in their density profiles (Kontizas et al. 1987). This can be explained as either due to the weak-gravitational attraction of the parent galaxy during the clusters' dynamical evolution, or that these clusters are in the stage of core oscillation (Heggie 1989). (2) The majority of small LMC star clusters of our sample (80%) seem to be relaxed, most likely by ''two-body'' encounters, considering that the age of their stellar content is old enough to allow this mechanism to be effective. (3) We cataloged all small clusters in three LMC central regions where 93 new clusters have been detected. Coordinates, apparent sizes, and colors were given for the first time (Kontizas et al. 1988). These clusters were found to have small masses and sizes (103 solar mass < M < 104 solar mass, 14 pc < rt < 37 pc). (4) Small star clusters with similar dynamical parameters were also found situated at distances larger than 4.5 from the rotational center of the LMC. Their total dynamical masses are found to give a very good extrapolation to the LMC rotational curve. These lead us to the assumption of an extended disk in the LMC. Therefore the small intermediate-age (1.4 x 109 yr) clusters of the LMC occupy the extended disk of the LMC where the old stellar population is located. (5) The age of the stellar population for four star clusters was estimated from their HR diagrams and found to be 1.4 X 108-2 X 109 yr, confirming that the age range of the LMC small clusters is narrower than that of our own Galaxy since we did not find very young small clusters. (6)We have studied dynamically for the first time LMC clusters with masses smaller than 104 solar mass and found that the mass spectrum of the small LMC star clusters coincides partly with the mass spectrum of the galactic open clusters, but extends to larger values. (7) Finally we have compared the frequency distribution of the derived dynamical parameters of all studied clusters with those of the open clusters of our Galaxy. We found that faint and old globular LMC clusters form one disk system, which is similar to the open-cluster system of our Galaxy. The LMC clusters' disruptive mechanism must be weak and does not seem to affect the small- or intermediate-mass star clusters. Further progress in understanding the formation and early evolution of the LMC clusters requires a detailed study of the conditions prevailing in the inner regions of the molecular clouds from which they are probably formed.

The invention discloses a coordinated-deformation energy-absorption anchor rod suitable for mining a high-stress large-deformation rock mass. The rod body of the anchor rod mainly comprises an elongated anchoring section straight rod body (1) and an energy-absorption section bending rod body (2), wherein one end, close to the energy-absorption section bending rod body, of the rod body is provided with a threaded section (5); a fastening nut (4) is screwed on the threaded section (5); and a steel pallet (3) is sleeved between the fastening nut (4) on the threaded section (5) and the energy-absorption section bending rod body. The anchor rod is mainly characterized in that: a wavelike bending energy-absorption section in a specific length and a specific shape is mechanized on a long straight threaded steel rod body in a heat treatment mode; the energy-adsorption section restrictively allows a wall rock to deform properly and simultaneously absorb the deformation energy of the rock mass until reaching total allowable deformation quantity meeting a design requirement. In the process, the supporting force of the anchor rod is increased gradually; and finally, after the bending section is completely straightened and a yielding effect controlled by a high-stress roadway ground pressure is achieved, the anchor rod becomes a high-strength rigid resin anchor rod for providing greater supporting force for a supported wall rock mass.

Background/Objectives: This study aims to automate breast cancer detection to either benign or malignant. This process helps physicians for early detection of the tumor. Methods Analysis: We propose a novel method for breast cancer detection called CARA. The proposed method is based on Circular ROI (Region of interest) of the tumor. The circularity of the tumor determines the tumor type either benign or malignant. Findings: The proposed CARA method achieves high accuracy rates compared to other previous work. CARA exceeds other previous work by more than 20% in accuracy. Moreover, CARA outperforms other previous work in all performed trials. Additionally, the proposed CARA method outperforms other previous work with respect to execution time. Improvements/Applications: Automatic classification of breast cancer to either benign or malignant in order to help physicians for early detection of the tumor.


One of the basic criteria for making decisions on the exchange is stock returns. Stock returns has, in itself, information content. Most of actual and potential investors use stock returns in financial analysis and forecasts. Today, investment includes the bulk of economic activities. One of the requirements of development in any society is investment. Any investor to invest, pays attention to several factors, most notably of which is the return on investment, and prediction of the return obtained from that investment. In different cases of investment (assuming constant risk), the investor usually chooses the case, which has higher return.

Objective To explore the influence of styptic fiber on clotting time in rabbits so as to provide experiment data for its development.Methods Onto 0.1 mL aliquots of citrated anti-coagulant rabbit blood placed in a surfacial plate 25 ul of 0.2 mol·L-1 CaCl2 solution was dropped,and mixed well with glass stirrer;the resulting mixture was immediately capped with a piece of styptic fiber(test product group)or absorptive gelatin sponge(positive control group)of 2 cm diameter.Then,the surficial plate was rinsed with 30ml of purified water at 5,10,20,30,40 and 50 min after capping;the rinsings were allowed to stand for 1 h and were subjected to OD determination at a wavelength of 541 nm.The above procedure was repeated twice,the average value of the twice experiments was taken for evaluation of the hemostatic effect of test product.For negative control group,all procedures except for capping were same as the test product group.The haemostatic effect was judged by percent OD relative to OD at 0 min in negative control group(OD 0 min)(OD 0 min was considered as 100%);if OD value at a time was less than 80% of OD 0 min,it should be designated as primary clotting time(PCT),less than 20% as complete clotting time(CCT).Results The measured PCT was 20min for both negative and positive control groups;CCT was 50,30 and 5 min for negative control,positive control and test product groups,respectively,showing the test styptic fiber had a CCT 8 times shorter than untreated blood,10 times shorter than negative control and 6 times shorter than positive control.Conclusions The test styptic fiber has powerful hemostatic effect.


This was an interlocutory appeal under s. 35 of the Criminal Procedure and Investigations Act 1996, on a ruling of law made at a preparatory hearing. The two appellants had been charged with unlawful sexual intercourse with a girl. (the same girl in each case), who was under the age of 16 years. In each case the fact of sexual intercourse was admitted. It was conceded by the Crown that the girl could well have given the impression that she was over 16. There are two statutory offences of unlawful sexual intercourse with a girl. The first relates to girls under the age of 13 years; the second to girls under the age of 16 years. In both cases, as a matter of law, the fact of consent of the girl to sexual intercourse is immaterial. There is no statutory defence to an allegation of unlawful sexual intercourse with a girl aged under 13 years. However, a statutory defence is provided for unlawful sexual intercourse with a girl aged under 16 years. This is to be found in s. 6(3) of the Sexual Offences Act 1956, which reads:


Abstract The Surrealist artist Richard Oelze's postwar enterprise was one of inner reflection and personal questioning linked to the broader project of coming to terms with the past. The essay takes a critical view of his artworks and his automatist Wortskizzen to assess the manner and extent to which Oelze utilizes his artistic practice as a mode of working through his, and Germany's, complicity with the Nazi regime. Analysis of the Wortskizzen exposes how verbal probing informs Oelze's visual expression of inner turmoil, while implied gaps and voids in paintings and drawings puncture space as well as time, illuminating memory and blending the past with the present. Oelze's serious play with word and image in turn invites his viewers to release repressed memories through reflective contemplation.

In autonomous mapping surveys the autonomous underwater vehicle (AUV) cannot rely on receiving position aiding from a surface vehicle or any other external infrastructure. The AUV can however use any payload sensor to restrict the position error drift in the navigation system. In this paper we consider using the bathymetric sensor in line-to-line terrain navigation. Terrain navigation will limit position error growth, and also ensure enough overlap between the lines such that the survey area is covered. We show that sparse map coverage from a line of bathymetry leads to a bias when used in a straightforward implementation of the point mass filter terrain navigation algorithm, and we develop a modification to the algorithm that handles this robustly. The algorithm achieves good performance when tested off-line on real data from a HUGIN AUV equipped with the HISAS 1030 interferometric synthetic aperture sonar.


Much has been written in the past twenty-five years about the character of the training of the high-school teacher. One of the outstanding contributions along this line is the report of the Committee of Seventeen.' Many courses for the training of high-school teachers, which no doubt were inspired by this report, have been constructed and are being tried out in different states of the Union. The state teachers' colleges in Pennsylvania have established a four-year course for the preparation of high-school teachers leading to the degree of bachelor of science in education. They have also established four-year courses in specific fields-public-school art, commercial education, health education, and public-school musicwith corresponding suitable degrees. Even though good courses have been established in the various institutions of the state, some important problems still remain to be solved. One of the first problems encountered by the prospective teacher is: What shall I teach? The problem of the teacher-training institution is: What shall the prospective teacher be prepared to teach? As far as can be determined, little has been done in Pennsylvania that will give the information necessary for answering these questions in an intelligent manner. There has been no extended nor adequate study of the number and the distribution of specific subjects assigned to teachers in the high schools in Pennsylvania. When the prospective teacher undertakes to select the subjects which he should be prepared to teach, he is guided by the whims of his fellow-


Nanospaces are ubiquitous in the realm of biological systems and are of significant interest among supramolecular chemists. Understanding chemical behavior within nanospaces offers new perspectives on biological phenomena in Nature and opens the way to highly unusual and selective forms of catalysis. Supramolecular chemistry exploits weak, yet effective, intermolecular interactions such as hydrogen bonding, metal-ligand coordination, and the hydrophobic effect to assemble nano-sized molecular architectures, providing reactions with remarkable rate acceleration, substrate specificity, and product selectivity. In this minireview, we will focus on the strategies that supramolecular chemists use to emulate the efficiency of biological processes, and elucidate how chemical reactivity is efficiently controlled within well-defined nanospaces. Approaches such as orientation and proximity of substrate, transition state stabilization, and active site incorporation will be discussed.


In this paper I analyze reviews taken from a popular wine review website. I use linear regression to tune a model suited for predicting wine ratings. I compare a two models and select the best one with the best parameters using k fold cross validation. The results indicate that better predictions come from using more of the features, rather than less of them. This suggests that both the age of a wine as well as the varietal are important when predicting the rating of a particular wine.


A grounded theory research is of significant value when examining in depth the key factors impacting profitability in the food industry. Five Israeli food companies, which are different in age, size and their business models, were selected to optimally serve the purposes of the study. The selected methodology included a grounded theory approach, a purposeful sampling involving 15 executives from the five above-mentioned companies and two interview formats: An open-ended interview for the five CEOs and a structured interview adopted from Preziosi's (1980) Organizational Diagnosis Questionnaire for the remaining managers. This study revealed additional and well-grounded insights into the decreasing profitability of the food companies under investigation from 2010 to 2013. The findings are on the whole in agreement with the reviewed literature. However, a number of significant inconsistencies were also identified. On the theoretical level, the researcher recommends further investigation of additional Israeli and global food companies in order to increase the external validity of the results. On the practical level, the researcher recommends for government and industrial institutions to increase the viability of companies within the food industry by addressing the high level of concentration and diminishing its effect, especially concerning the SME. This research has enriched the current body of knowledge regarding the struggle for profitability of food companies by outlining nine key categories perceived to be the predominant causes of the decreasing profitability issue. This study is therefore of significant value to the current theoretical literature regarding both the Israeli and the global food industry.


Detailed cytological studies of serial sections have been performed on 85 golden hamster embryos ranging between 9 and 16 days (4–27 mm) of embryonic development.


We have fabricated dc superconducting quantum interference devices incorporating Josephson tunnel junctions with an inductance of about 2 pH and a capacitance per junction of about 0.3 pF. The lowest measured flux noise energy was 3.2 h/ at 1.4 K at a frequency of 202 kHz. When the 1/f noise was subtracted, the white noise energy decreased from around 3h/ at 4.2 K to below 2h/ at 1.4 K.


Across various domains, the ontologies are learned from relational models of databases for the purpose of integrating data to a semantic layer. Through mappings among ontologies, new semantic applications can visit these integrated data with semantic query language like SPARQL. However, the traditional systems are still running on databases with SQL. In this paper we analyze the translations from basic relational algebra operations to SPARQL queries under an ontology learning approach. The result shows that SPARQL is relational completeness in the scenario. So the database-based application could be migrated from relational database onto semantic layer by replacing SQLs with SPARQL queries.


This article discusses Student-centred Leaming (SCL) approach. It is argued that while SCL application is related to learning activities in classrooms; it is also strongly related to the efforts of motivating leamers, involving them in creating goals of learning, and encouraging them to find the relationship between their leaming and their liie experience. Furthermore, it is explained that the application of SCL is partly related to cultural issues, both from teacher and learner perspectives.

Gail Burrill Life has changed enormously since I grew up in Fisher, Minnesota. Over the years, we faced many challenges and made choices that helped us meet those challenges as we kept up with changes in agriculture, manufacturing, transportation, entertainment, and education. Today, we in mathematics education face a new set of challenges and choices as our changing society becomes information based, demanding more mathematical literacy from every member. Our mission as a Council and as teachers provides a framework for helping us meet challenges and make choices. In addition, I offer a guiding principle that we might each use in our own decision-making process. Which choices will better enable our students-all students-to learn mathematics? How will the consequences of a given choice help students learn algebra and geometry and internalize number, measurement, or data? Two major challenges go hand in hand with this guiding principle: (a) the need to change classroom practice and (b) the need to seriously rethink the definition of basic and what it means for all students. Frontiers, a publication of the National Science Foundation (NSF), in June 1995 contained an article titled "Mathspeak, the NSF Tie That Binds," which listed the four most significant contributions of mathematics to science and engineering: conceptualization, computation, visualization, and prediction. These are basic. My job as a teacher is to develop the ability in my students to do them because they are important for future citizens and workers, whatever their careers. Consider the problem in Figure 1, which was presented at the NCTM's 1997 New Orleans regional conference by Ruth Cossey.


THE PUERTO RICO Field Station of the National Communicable Disease Center, Public Health Service, conducts laboratory and field studies to evaluate pesticides for use as molluscicides against Australorbis glabratus. The tests described in this paper consisted of laboratory evaluations of 15 compounds and field appraisal of the two most promising. The compounds tested are listed by their trade and chemical names; the letters in parentheses are supply references. Bayluscide (2-aminoethanol salt of 2',5-dichloro-4'-nitrcraalicyanilide) and sodium pentachlorophenate (NaPCP) were used for comparison standards in the laboratory tests.


In this paper, the performance of the two beamforming methods, conventional and MVDR QR-based, are used for multiple signal extraction under conditions of jamming using three various array configurations. The quality of source localization under conditions of strong broadband interference is evaluated in terms of the following quality measures estimated at the beamformer output – the angular resolution of signals, the peak sidelobe level and the signal-to-interferenceplus-noise ratio (SINR) improvement. The simulation results demonstrate the better and more stable angular resolution of signals, provided by the MVDR method, compared to the conventional beamforming method.


The care and training of voice must be based on the understanding of the function of a normal person's speech organs and the causes that lead to the disease of the voice.A few scientific methods of enunciation can be employed to train the voice so that the function of its speech organs is strengthened and the voice is protected.


Embodiments are directed to an apparatus comprising: at least one processor, and memory having instructions stored thereon that, when executed by the at least one processor, cause the apparatus to: receive a request for elevator service, and cause at least one resource associated with a service unrelated to the use of the elevator itself to be assigned responsive to receiving the request for elevator service.


The dynamics of catenary moorings in the region surrounding the touchdown point are studied using experiments and numerical simulations. When the touchdown point speed exceeds the transverse wave speed of the mooring line, a shock forms in the tension. The analytical derivation of the shock criterion is reviewed, and the criterion is verified quantitatively using the experimental results. Shocks during upward motion of the mooring are manifested as snap loads in the tension record. Shocks during downward motion appear as slack tension at the touchdown point. Numerical simulations using an elastic foundation approach to modeling bottom interaction are accurate for cases with and without shocks. Simulations in which tension shocks are present are much more sensitive to the numerical parameterization of the bottom and the artificial bending stiffness of the mooring chain than cases in which no shocks are present. Analysis of a full-scale oceanographic mooring found unloading shocks under a wide range of forcing conditions, but loading shocks only during storms. * ISOPE Member.

A relativistic backward wave oscillator for directly generating circularly polarized TE11 mode is proposed. In the device, the electrodynamics structures are divided into two groups in azimuth, each group consisting of two opposite 90° sectors, to produce two orthogonal TE11 modes. The axial position of the two groups is shifted to each other with a quarter of slow wave structure period to achieve a 90° phase difference between the two orthogonal TE11 modes. In particle-in-cell simulation, a circularly polarized TE11 mode with 1.5 GW power has been demonstrated. The amplitude ratio between the two orthogonal TE11 modes is smaller than 0.5 dB, and the phase difference is close to 90°.


The objective of the present study was to evaluate the nematophagous capacity of two Duddingtonia flagrans strains: one native from France, and another one from Mexico. Three groups of 17 Petri dishes each containing corn fluor-agar media were organized. Each strain was cultured in the dishes of two of the groups; those of the third group served as the control one. Petri dishes of the three groups included 150 Panagrellus redivivus larvae/dish. Five days later they were quantified to evaluate larval reduction percentage. Both strains showed significant reductions (P <0.05) as compared with the control group. Mexican and French strains exhibited reductions of 98.9% and 97.7%, respectively.

Science and technology culture is a new and relative independent system of social subculture, having features of universality, foundation and active creativity,it has been infiltrating everywhere the productions and lives of human beings through three levels of materials,systems and views. This article analyses interaction between culture, science and technology education and development of science and technology and points out, in our times when we are devoting major efforts to developing productive forces of science and technology,we must also pay much attention to building the culture of science and technology.


BACKGROUND:The role of sessile serrated adenomas (SSAs) as precursors of proximal colon cancers has been well documented. However, their role as precursors of cancer in inflammatory bowel disease (IBD) patients is not as established. METHODS:We analyzed 2 patients with longstanding IBD found to have diffuse segmental serrated transformation of the right colon. The first case was a 53-year-old female with ileocolonic Crohn's disease. The second case was a 66-year-old male with a history of extensive ulcerative colitis. The patients were assessed at a tertiary hospital. RESULTS:The first case was identified following surgical resection for colonic stricture. Her pathology specimen revealed extensive, diffuse serrated epithelial changes and low grade adenocarcinoma. In the second case, confocal microscopy was used to identify a segment of right colon extending from cecum to mid ascending colon consistent with serrated adenomatous transformation. Pathology confirmed changes characteristic of serrated adenomas as well as foci of low and high grade dysplasia. CONCLUSIONS:We describe 2 cases of segmental serrated transformation involving the right colon in patients with IBD. In both cases, diagnosis could not be made with conventional endoscopy with random biopsies alone. We propose that IBD patients undergoing routine surveillance colonoscopies with multiple right-side biopsies revealing serrated epithelial changes should undergo further testing with chromoendoscopy and/or confocal endomicroscopy to identify the extent of serrated changes. This will allow prompt identification of this subset of patients with diffuse segmental serrated adenomatous transformation that carries significant pre-malignant risk.


Visual block programming environments can be defined as those programming environments that rely on objects rather than words to code the program. These types of environments are characterized by facilitating the task of the people who carry out the programs. This is mainly since they are more visually friendly. In addition, with this type of environment the person who makes the programs will not get the famous syntactic errors that characterize the programming tasks with textual programming languages. Along this paper, a set of tools commonly used in educational robotics are showed. Furthermore, a deep analysis in two of these tools are detailed. Additionally, some educational scenarios are detailed, as long as their relationship to students' competencies and how to drive the scenarios in order to accomplish with the competencies. Finally, a study of the results from experience is included.


Halogenated compounds, especially fluorine and chlorine, play a key role in drug development. They account for a large proportion of all approved drug molecules. The importance of these two halogens stems from their remarkable effects on biological activity and pharmacokinetic properties. The study presented here aims to give the results obtained by the DFT methods and in silico medicinal evaluations of a newly synthesized small molecule. The small molecule belongs to the Schiff base class of organic compounds and is substituted with halogen atoms. The tetrahalogenated compound (THSB) Schiff base, 2-(((2,4-dichlorophenyl)imino)methyl)-3,4-difluorophenol, was first synthesized via the classical condensation method and then characterized by spectroscopic techniques. The THSB optimized by the B3LYP method was evaluated in terms of geometrical parameters, surface area (MEP and Hirshfeld analysis) and secondary interaction analysis, NLO properties, and electronic properties (HOMO-LUMO and UV-Vis). Second, THSB was evaluated regarding medicinal chemistry, physicochemical and pharmacokinetic properties, and toxicity (ADMET). Then, we comprehensively investigated the potential biological targets of THSB. Using the results of the SwissSimilarity analysis, we investigated the antagonistic effects of THSB against serotonin 5-HT2A and dopamine D2 receptors. Docking results were compared with the known antipsychotics, clozapine and risperidone. THSB showed a higher antagonistic effect than clozapine for the D2 receptor. However, risperidone proved to be the most effective antagonist for both targets. The binding energies of THSB, risperidone, and clozapine were -8.30, -11.84, and -8.07 kcal/mol, respectively, for D2; those of THSB, risperidone, and clozapine were -6.94, -11.47, and -10.10 kcal/mol, respectively, for 5-HT2A.


In this paper, a new suggested system for speaker recognition by using hidden markov model (HHM) algorithm. Many researches have been written in this subject, especially by HMM. Arabic language is one of the difficult languages and the work with it is very little, also, the work has been done for text dependent system where HMM is very effective and the algorithm trained at the word level. One the problems in such systems is the noise, so we take it in consideration by adding additive white gaussian noise (AWGN) to the speech signals to see its effect. Here, we used HMM with new algorithm with one state, where two of these components, i.e. (π and A) are removed. This give extremely accelerates the training and testing stages of recognition speeds with lowest memory usage, as seen in the work. The results show an excellent outcome. 100% recognition rate for the tested data, about 91.6% recognition rate with AWGN noise.


To the Editor.—The excellent review entitled ''Atypical Spitz Tumors: A Diagnostic Challenge'' by Harms and colleagues, recently published in Archives of Pathology & Laboratory Medicine, outlines the clinical features and course, the histopathology, the special techniques used in the differential diagnosis, and the current treatment of atypical Spitz tumors (ASTs). As in other previously published articles, the review concludes that the diagnosis of ASTs is challenging because these tumors can be misdiagnosed as benign Spitz nevi or as spitzoid melanom a s , w i t h c o n s e q u e n t r i s k s , respectively, for undertreatment or overtreatment. Moreover, regarding the possible nature of ASTs, Harms et al state that it is ''controversial whether ASTs should be considered spitzoid neoplasms sui generis or a provisional category of diagnostically challenging lesions,'' adding that ''[b]oth may be true.'' 1 In summary, the authors consider ASTs a heterogeneous group of melanocytic tumors including (1) Spitz nevi and spitzoid melanomas with ambiguous features and, therefore, of difficult diagnosis; and (2) melanocytic neoplasms different from Spitz nevi and from spitzoid melanomas, with peculiar clinicohistologic and biological characteristics (sui generis). An analogous opinion has been recently expressed by Lallas et al. In a systematic review, in which the clinicopathologic characteristics of 541 ASTs were analyzed, these tumors appeared to have a considerable rate of positive sentinel nodes (119 of 303; 39%), a relatively high rate of nonsentinel node involvement (18 of 97; 19%), a very low incidence of local recurrences (5 of 541; ,1%), a small but significant rate of regional metastases (16 of 541; 3%), a very small rate of distant metastases (6 of 541; 1%), and a very low associated mortality (6 of 541; 1%). Discussing their results, the authors posed the question about the nature of ASTs, basically recalling 2 different hypotheses: (1) ASTs are a confused assemblage of morphologically ambiguous benign nevi with associated benign cells in lymph nodes and of morphologically ambiguous malignant melanomas; (2) ASTs are a group of biologically intermediate tumors, that is, melanomas with a relatively good prognosis. Unfortunately, neither article discussed the problem any further. Actually, the 2 invoked hypotheses on the nature of ASTs deserve to be accurately examined, because they open 2 very different scenarios. Hypothesis 1 implies that ASTs––belonging to the same cellular lineage, with the same clinicopathologic characteristics, not distinguishable on clinical and/or histologic grounds, or with the available special techniques––may be different tumors with totally different biology, some ASTs being benign and some malignant. This is to say that these tumors cannot be appropriately diagnosed on the basis of their morphology or structure, but only a posteriori on the basis of follow-up data and of the final outcome. If a principle like this were extensively applied, a lesion presently diagnosed as ''superficial spreading melanoma'' should be a posteriori classified as a ''melanoma'' only if the patient developed metastases or died, but regarded as ''nevus'' or as ''atypical nevus'' if the patient survived. This not only is illogical but also leads to an insurmountable diagnostic impasse because the same histologic appearance may not imply the same diagnosis. Differently, hypothesis 2 implies that ASTs––belonging to the same cellular lineage, with the same clinicopathologic characteristics, not distinguishable on clinical and/or histologic grounds, or with the available special techniques––cannot be biologically different tumors but are to be regarded as a unique group of neoplasms. In this case, the admitted existence of a reliable correspondence between a given histologic appearance and a given diagnosis permits these tumors to be diagnosed on the basis of their morphology, overcoming the diagnostic impasse. Therefore, at least pragmatically (but also theoretically), hypothesis 1 should be rejected, because it inhibits the diagnosis and makes ASTs ''unintelligible''; hypothesis 2 should be accepted, because it makes the diagnosis possible and could solve many connected problems. In fact, if ASTs are a unique group of tumors, diagnosable clinically and histopathologically, and if they represent a unique clinicopathologic entity, their nature ceases to be obscure. They are not nevi and are not benign, because they are capable of metastases and, albeit rarely, of causing death. However, the low rates of distant metastases and of deaths (in part because the tumors with the characteristics of AST and unfavorable outcome are currently separated a posteriori under the label of spitzoid melanomas) demonstrate that they properly are malignant tumors, albeit with a relatively favorable prognosis. In other words, they possess a low malignant potential. It has been highlighted that considering the malignant potential of tumors as an all-or-none phenomenon is an oversimplification. The paradigm ''benign versus malignant,'' based on the clinical course of the disease, seems to be a rather rough approach to a biologic property (the malignant potential) of tumors, which in reality could have a different expressivity. It is not possible to precisely estimate the malignant potential of a given lesion, but, certainly, it is not the same in all tumors and can be approximately defined, at least, as low, moderate, or high. Available data show that ASTs are malignant but seem to have a relatively low malignant potential. A tumor with low malignant potential is not necessarily a tumor having an invariably limited metastatic capability (eg, a tumor capable of regional but not distant metastases). It can be a tumor with a metastatic rate, statistically lower than expected. In effect, ASTs have metastatic and associated mortality rates that are statistically lower than ''conventional melanomas'' ; they could be properly considered as low-grade melanomas, as Sophie Spitz did in 1948. The notion that ASTs constitute a unique clinicopathologic entity and are melanomas, albeit of low-grade, may explain many if not all issues, including why they are so similar to spitzoid melanomas, why ASTs and spitzoid melanomas may be histologically indistinguishable, why they are not confidently separable by any special technique, why more than occasionally the attempts to differentiate them fail, and finally, why the diagnostic concordance among pathologists is so low.


The altar scene in Revelation 6:9–11 has been interpreted as a positive image of martyred saints being presence with God in heaven. This article, however, challenges this traditional assumption. Based on Roman imperial coinage, especially those coins with images of altars, it is likely that John portrayed the altar in his narrative as not representing the heavenly altar of God but the imperial altar of Rome. John takes well-known Roman images and challenges his readers to resist the temptation these altars represent as symbols of the false ideology espoused by Rome. He also illustrates how these altars, like the cross of Christ, may become the symbol for his readers' martyrdom. This article also suggests that architectural images of altars on Roman coins can provide a way to understand the strange position of the martyred ones who are "under the altar."


This study aims to modify the agricultural waste, that is, Sorghum bicolor L. by means of phthalic anhydride for the enhanced removal of reactive dyes. This modified Sorghum was characterized by means of using Fourier-transform infrared spectroscopy-spectra, scanning electron microscope, pHpzc, and by Boehm's titration for the determination of acidic and basic groups. Alizarin Red S (ARS) and Bromophenol blue (BPB) were used as a substrate for removal. The observed optimum values were 0.1 g/50 ppm for ARS and 0.1 g/30 ppm for BPB at neutral pH within 25–30 min at room temperature. The equilibrium statistics fitted well in the Langmuir equilibrium model with maximum adsorption capacities of 285.71 and 65.78 mg g–1 for ARS and BPB, respectively. The kinetic data was followed by the pseudo-second-order rate equation. The thermodynamics study revealed that the process was exothermic and spontaneous.


The main challenges for embedded real-time systems which use battery as their power supply are both to satisfy the requirements of real-time systems and minimize the energy consumption. This paper studies the energy saving problem for DAG (Directed Acyclic Graph) tasks in soft real-time systems with heterogeneous multicore processors. Since soft real-time systems can tolerate occasional time violations and tasks are completed before deadlines with a given probability, this paper proposes a novel processor and voltage assignment scheme - Adaptive Processor and Voltage Assignment with Probability (APVAP) to realize the minimum energy consumption which can satisfy the requirements of time constraints under the given probability. Most of previous work focuses on multicore processor task assignment for predecessor and successor (P-S) tasks. However, this paper introduced affinity to indicate successor tasks can be re-allocated to more appropriate cores according to task features and workload. Besides, this paper introduces the concept of data migration energy (DME) to compute the transmission energy when a task is migrated to a different core and adopts Ratio between Time and Energy (RTE) to determine the most suitable tasks for migration to reduce energy consumption at the cost of execution time. The experimental results demonstrate that our approach outperforms state-of-the-art algorithms in this field (maximum improvement of 30.7%).


The utility model discloses a safe abdominal muscle exercise device with a dumbbell function. The safe abdominal muscle exercise device comprises a pedal, guide rails, abdominal muscle wheels, bearings, rollers and a handle. The rollers and the handle are connected through the bearings to form the abdominal muscle wheels, the guide rails are two in number and are parallel, one ends of the guide rails are fixedly connected through the pedal, and the two rollers are embedded in grooves of the two guide rails. Compared with the prior art, the safe abdominal muscle exercise device has the function of the abdominal muscle wheels and also has the dumbbell function, can effectively guarantee safety of a body builder, is simple in structure and convenient to use, and has application and popularization value.


Even as deaf and hard of hearing filmmakers and activists repeatedly call for quality captions on all video content, many non-deaf filmmakers have managed to remain unaware of the need for and purpose of captions. Implicit biases drive many filmmakers to exclude access from their budgets and their films. These biases include a notion that caption users are not a viable audience, concerns that captions will threaten the beauty of video images by covering part of the screen, and an audist attitude that any level and quality of transcription of spoken dialogue must be adequate. The author is a hearing captioner and filmmaker. In this essay, she reflects on how she advocates for film accessibility through captions. She describes her strategy, how she frames "onscreen real estate," and responses from filmmakers for captions, including the hopeful way that some say thank you. Quality captions are contrasted against woefully inadequate captions—or "craptions"—provided automatically by YouTube and by companies with cut-rate services. The author considers a focus on inviting access rather than waiting for a compliance-based method of only captioning a film when the filmmaker learns it is required.


Species with highly restricted distributions are vulnerable to extinction, and modification of natural habitats within their small ranges is a primary threat to their persistence. Expansion of urban development significantly impacts natural habitats and, therefore, threatens local diversity. The Mexican axolotl, Ambystoma mexicanum, is a strictly aquatic species that persists currently in two highly threatened and isolated populations. The current habitat remaining for these species are remnants of a historically extensive lacustrine system that occupied the entire Valley of Mexico, but has been destroyed by the growth of Mexico City. Unexpectedly, a third viable population of axolotls has been found in Chapultepec Park, a public recreational area in the heart of Mexico City. Phylogenetic and haplotype network analyses of mitochondrial DNA sequences confirmed low genetic differentiation and a recurrent lack of monophyly in many of the taxa belonging to the Ambystoma tigrinum species group, including A. mexicanum, but clustered the Chapultepec samples with other A. mexicanum samples. Our data revealed higher haplotypic diversity in A. mexicanum populations than previously recorded, due to new haplotypes from Chapultepec Park. We found high incidence of parasites and deformities among individuals in this population, which could negatively impact their viability. Our results emphasize the important role that artificial or semi-natural urban habitats can play in the conservation of highly threatened species.


Future robots need transparent interface that regular people can interpret, such as an emotional human-like face. Moreover, such robots must exhibit behaviors that are perceived believable and life-like. In this work we propose the use of fuzzy logic for effectively constructing the whole behavior system of these robots. This not only simplifies the design tasks, but also enriches human-robot interaction. The latter claim is justified by effortlessly generating intermediate and blend of emotions from a few basic emotions. Additionally, fuzzy motor commands yield smooth life-like motions and therefore improve believability.


On the basis of results of the all-Russian polls executed with assistance of the Russian Science Foundation (project No. 17-78-30029 "Cognitive mechanisms and discourse strategies of overcoming socio-cultural threats in historical dynamics. A multidisciplinary research") in 2019 and in 2020, some aspects of transformation of social well-being of the population in the conditions of COVID-2019 pandemic were analyzed. Considering the spread of coronavirus infection as a social threat, revealing shifts in the assessment of the economic and political situation in Russia, in the self-assessment of their own well-being, confidence in the future and in the attitude to the population to power, it was concluded that the mood of citizens was shifting into a negative direction, which was determined by a number of circumstances of objective and subjective nature. The study found that the highest degree of anxiety among Russians is still caused by socio-economic issues. At the same time, the coronavirus pandemic has increased society's demand for an adequate state response to such extreme situations. When comparing the opinions of respondents about effectiveness of the activities of regional and federal executive authorities during a pandemic, the authors come to the conclusion that regional and local authorities are growing in trust and popularity, which is associated with the transfer of responsibility for resisting coronavirus to the level of subjects of the Russian Federation.

Abstract Background  The primary concerns with operating on patients in the office setting are insufficient sterility and lack of appropriate resources in case of excessive bleeding or other surgical complications. This study serves to investigate these concerns and determine whether in-office hand surgeries are safe and clinically effective. Methods  A retrospective review of patients who underwent minor hand operations in the office setting between December 2020 and December 2021 was performed. The surgical procedures included in this analysis are needle aponeurotomy, trigger finger release, foreign body removal, mass removal, and reduction in a finger fracture with or without percutaneous pinning. All fractures, which primarily included metacarpal and phalangeal fractures, were subsequently splinted. Sterility and hemostatic support were achieved via the Wide-Awake Local Anesthesia No Tourniquet (WALANT) method. Major complications were defined as infection, major bleeding, and neurological deficits. Minor complications were defined as prolonged pain, prolonged inflammation, residual symptoms, and recurrence of symptoms within 1 month. Results  Five patients (3.8%) returned to the office for pain, inflammation, or stiffness of the affected finger, with two of the five returning with symptoms associated with osteoarthritis or pseudogout flare-ups. Five additional patients returned due to residual symptoms or recurrence of the primary complaint within 1 month of surgery. No patients experienced exogenous infection. Conclusion  The absence of major complications and high success rate for minor hand procedures shows the high degree of safety and efficacy that can be achieved via the in-office setting for select procedures. While proper patient selection is key, our result shows the in-office procedure room setting can offer the necessary elements of sterility and hemostatic support for several common hand surgeries.

Among theoretical fields addressing the conceptualization of interrelationships between nature and society, patrimonial approaches remain relatively unexplored. Stressing the multiplication of local dynamics where elements of nature are redefined as "patrimonies" (ranging from local patrimonies to world heritage) by various social groups, this conceptual field tries to qualify these dynamics and their determiners to understand how they allow us to better address contemporary environmental challenges. Through a multidisciplinary approach in social sciences, centered on rural forests, we analyze the multiplication of patrimonial processes in forest development at various scales. First, we elaborate on the concept of patrimony and on patrimonial processes and present the current construction and dynamics of forest patrimonies. A crucial question concerns the links that form between the many spatial-temporal levels where these processes develop. Moreover, these patrimonial processes can be quite divergent, not only across scales from local to global, but also between "endogenous" (or bottom-up) and "exogenous" (or top-down) processes. We present two detailed examples in Morocco and Sumatra, where patrimonial constructions are developing simultaneously at various scales and through various actors who treat the forest in very different ways. Drawing from these examples, we discuss how and why the simultaneous development of different, often overlapping, patrimonial constructions along these scales allows collaboration or, conversely, can lead their holders into conflict. Lastly, we discuss the contribution of patrimonial concepts to resilience thinking and social-ecological systems theory. Patrimonial approaches have traditionally been developed by scholars working in the fields of private law, architectural monuments, and culture. For a few decades now, patrimony and patrimonial processes have been redefined and appropriated as meaningful analytical categories by other human and social sciences such as sociology, anthropology, geography, or economics in order to highlight new trends in the relationship between societies and their "natures." Stressing the multiplication of local dynamics, where elements of nature are redefined as "patrimonies" by various social groups (from local communities to international agencies), this conceptual field tries to qualify these dynamics and their determiners and to understand how they address contemporary environmental challenges. Our paper discusses the relevancy of these patrimonial concepts for analyzing the dynamics of forest-society relationships. We discuss both conceptual approaches and concrete patrimonial processes using the example of rural forests.


With the growth of the Internet users,people's purchasing online is also increasing.Accordingly,consumers' trust on online store is paid high attention.Through systematical review of various literatures discussing how consumers trust online store,the author proposes a consumer's trust model in B2C transactions and nine propositions.After an AMOS based empirical study on the 230 valid samples received through field study,it is found that store reputation,store size,website quality,situational normality,structural assurance,cooperative norm,interaction,with exception of legal bonds,positively influence online consumer's trust,and online trust can further impact trust intention.The findings state that online stores can improve consumer's trust through improving store competence,enhancing website quality,building system trust mechanism and pushing interaction.


Purpose: ([N-methyl-]2-(4'-methylaminophenyl)-6-hydroxybenzothiazole, 1), a -amyloid imaging agent for the diagnosis of Alzheimer's disease in PET, can be labeled with higher yield by a simple loop method. During the synthesis of , we found the formation of by-products in various solvents, e.g., methylethylketone (MEK), cyclohexanone (CHO), diethylketone (DEK), and dimethylformamide (DMF). Materials and Methods: In Automated radiosynthesis module, 1 mg of 4-aminophenyl-6-hydroxybenzothiazole (4) in 100 l of each solvent was reacted with triflate in HPLC loop at room temperature (RT). The reaction mixture was separated by semi-preparative HPLC. Aliquots eluted at 14.4, 16.3 and 17.6 min were collected and analyzed by analytical HPLC and LC/MS spectrometer.

The LC/MS spectra of three products eluted at 14.4, 16.3 and 17.6 mins showed m/z peaks at 257.3 (M+1), 257.3 (M+1) and 271.3 (M+1), respectively, indicating their structures as 1, 2-(4'-aminophenyl)-6-methoxybenzothiazole (2) and by-product (3), respectively. Ratios of labeling efficiencies for the three products were in MEK, in CHO, in DEK and in DMF, respectively. Conclusion: The labeling efficiency of was the highest when MEK was used as a reaction solvent. As results of mass spectrometry, 1 and 2 were conformed. 3 was presumed.


Inquiry, an approach that departs from traditional mathematics teaching, empowers students through active participation and increased accountability in exploration, argumentation, evaluation, and communication of mathematical ideas. There is broad research consensus on the benefits of inquiry-based approaches to teaching and learning mathematics, including their potential to support equitable mathematics classrooms. While research has separately explored teachers' conceptions of inquiry and their efforts to enact the practice, little is known about the interplay between mathematics teachers' conceptions and enactment, and how it could be harnessed in professional development. In this study, we follow Alex, an experienced upper secondary mathematics teacher unfamiliar with inquiry, as he participates in a one-semester professional development course that draws on inquiry in multiple ways. His trajectory towards learning to teach through inquiry is revealed through patterns and shifts in his reflections and classroom actions. Our findings reveal significant developments in Alex's conception of inquiry and in how he realizes it in his classroom, identifying three paths that illuminate his inquiry trajectory: the teacher's role in inquiry interactions, a growing idea of inquiry, and orchestrating whole-class situations. In the interplay between enacting and reflecting, he moves from distributing authority separately between himself and 'the students' (as one unit) to fostering shared authority, a key aspect of empowerment, between himself and his students (as multiple voices) in both groupwork and whole-class episodes.


Piezoelectric nanowires have attracted much scientific interest in the last few years because of their enhanced piezoelectric coefficients at nanometer scale, with promises of efficient mechanical energy harvesters for autonomous integrated systems. This paper presents the design and, for the first time, guideline rules, based on simple analytical expressions, to improve the performance of a mechanical energy harvester integrating vertical ZnO piezoelectric nanowires. Additional simulations were carried out to account more realistically for device ge- ometry. We discuss the prospects of such an approach, based on design and material improvement.

This paper aims to replicate the semiparametric Value-At-Risk model by Dias (2014) and to test its legitimacy. The study confirms the superiority of semiparametric estimation over classical methods such as mixture normal and Student-t approximations in estimating tail distribution of portfolios, which can be credited to the model's uniqueness in combining strengths of both extreme value theory (EVT) models and other multivariate models. The author however discovers, in one instance, the infeasibility of the Dias model, and suggests a modification.

The relevance of increasing the efficiency of logging road trains by reducing the transport costs spent on the process of hauling timber is substantiated. The analysis of scientific works of foreign authors has been carried out, which made it possible to identify the most important factors influencing the process of the efficiency of timber hauling by timber road trains. A promising design of a two-chamber coupling device for a timber road train is proposed, which provides an increase in the energy efficiency of the timber hauling process. Based on the developed mathematical model and computer program, a preliminary assessment of the efficiency indicators of the proposed road train coupling device was carried out. It has been established that equipping a logging road train with a recuperative two-chamber coupling de-vice will allow generating a recuperated power of about 7.8 kW when the road train moves along an insufficiently equipped logging road. It was revealed that the optimal value of the diameter of the two-chamber hydraulic cylinder of the coupling device is 90 mm, while achieving the maximum value of the recuperated power and the minimum value of the longitudinal acceleration of the trailer with timber relative to the timber vehicle.


Objective To analyze the causes and mechanism of pulmonary and cerebral lipiodol embolism during transcatheter arterial chemoembolization(TACE) in patients with hepatocellular carcinoma(HCC),and to discuss the corresponding preventive and therapeutic measures.Methods Pulmonary and cerebral lipiodol embolism occured in 3 patients with HCC during TACE,the causes and mechanism were analyzed with review of relative literatures,in order to find out corresponding preventive and therapeutic measures.Results Three patients were all involved in massive HCC.The first patient,a 71-year-old woman,died 1 year after cerebral lipiodol embolism resulted from the third time of TACE.Acute dyspnea and unconsciousness developed in the other 2 male patients,following the procedure due to pulmonary and cerebral lipiodol embolism when the second and third time of TACE was performed,respectively.The chest condition and conscious state of both patients were improved after positive emergency treatment.Literatures had reported that 6 patients of cerebral lipiodol embolism were involved in embolism via inferior phrenic artery.Conclusion Pulmonary and cerebral lipiodol embolism is rare and severe complication of TACE.The most probable mechanisms of pulmonary and cerebral lipiodol embolism are the tumor's feeding arteries coming from intercostal artery and/or inferior phrenic artery,excessive lipiodol usage and opening potential arteriovenous fistula.It is vitally important to prevent pulmonary and cerebral lipiodol embolism during TACE.Once pulmonary and cerebral lipiodol embolism occurred,the positive emergency treatment must be immediately performed.

Abstract Many epistemic attitudes including belief and knowledge have already been examined to determine the extent to which they can be attributed to collectives. The epistemological literature on explanatory understanding and objectual understanding, on the other hand, has focused almost exclusively on individual subjects. However, there are many situations that can be described by sentences of the form "We understand P", "We understand why p", "Group G understands P", or "G understands why p". As I shall show, these situations can be classified into five categories: distributive, common, joint, deferential, and cooperative understanding. Based on a definitional scheme, according to which the general concept of understanding has a cognitive component, a factivity component, and an epistemic-pro-attitude component, this paper aims to analyse these five types.


Background Longitudinal studies investigating impact of exogenous sex steroids on clinical outcomes of asthma in women are lacking. We investigated the association between use of hormonal contraceptives and risk of severe asthma exacerbation in reproductive-age women with asthma. Methods We used the Optimum Patient Care Research Database, a population-based, longitudinal, anonymised primary care database in the UK, to construct a 17-year (1 January 2000–31 December 2016) retrospective cohort of reproductive-age (16–45 years, n=83 084) women with asthma. Using Read codes, we defined use, subtypes and duration of use of hormonal contraceptives. Severe asthma exacerbation was defined according to recommendations of the European Respiratory Society/American Thoracic Society as asthma-related hospitalisation, accident and emergency department visits due to asthma and/or oral corticosteroid prescriptions. Analyses were done using multilevel mixed-effects Poisson regression with QR decomposition. Results The 17-year follow-up resulted in 456 803 person-years of follow-up time. At baseline, 34% of women were using any hormonal contraceptives, 25% combined (oestrogen/progestogen) and 9% progestogen-only contraceptives. Previous (incidence rate ratio (IRR) 0.94, 95% CI 0.92 to 0.97) and current (IRR 0.96, 95% CI 0.94 to 0.98) use of any, previous (IRR 0.92, 95% CI 0.87 to 0.97) and current use of combined (IRR 0.93, 95% CI 0.91 to 0.96) and longer duration of use (3–4 years: IRR 0.94, 95% CI 0.92 to 0.97; 5+ years: IRR 0.91, 95% CI 0.89 to 0.93) of hormonal contraceptives, but not progestogen-only contraceptives, were associated with reduced risk of severe asthma exacerbation compared with non-use. Conclusions Use of hormonal contraceptives may reduce the risk of severe asthma exacerbation in reproductive-age women. Mechanistic studies investigating the biological basis for the influence of hormonal contraceptives on clinical outcomes of asthma in women are required.

140 Background: Metaplastic breast carcinoma (MBC) is a rare subtype that accounts for <1% of all breast carcinomas. MBC is frequently triple-negative and neoadjuvant chemotherapy (NAC) is often used in triple-negative breast cancer (TNBC). The objective of this analysis is to ascertain response rates of MBC to NAC as compared to non-metaplastic TNBC.

METHODS
We searched the Magee Women's Cancer Center of UPMC IRB-approved neo-adjuvant treatment database which contains outcome data on 594 patients treated from 2004-2010. 116 patients with triple negative breast cancer (ER /PR negative or ER /PR weakly positive [H score of 10 or less] and HER2 negative or indeterminate [HER2 1+ or 2+ without amplification by FISH]), were identified. Nine of these TNBCs had metaplastic subtype and two groups were analyzed: metaplastic breast carcinoma (MBC) (N= 9) and non-metaplastic breast carcinoma (NMBC) (N = 107). Tumor volume reduction (TVR), pathologic complete response (pCR), recurrence and mortality were compared in both groups.

RESULTS
Average follow-up in MBC group was 43 months and no patients were lost to follow-up. Average tumor size on presentation in MBC group was 4.47 cm while in NMBC group it was 3.33 cm. pCR was noted in 0/9 MBC and 43/107 NMBC cases (p = 0.0253). 6/9 patients had mastectomy, 2/9 had breast conserving surgery (BCS) and 1/9 patients did not have a surgery yet. Average TVR was 28% in MBC cases compared to 74% in NMBCs when cases with pCR were included (p = 0.0001) and 56% when cases with pCR were excluded (p = 0.0202). Follow up on 9 MBC cases revealed 1 recurrence and subsequent death (11%). Follow-up on 64 NMBC patients who failed to achieve pCR revealed 22 recurrences (34%) and 18 of them subsequently died (28%). Follow-up on 43 NMBC cases that achieved pCR revealed 3 recurrences (7%) and 1 death (2%).

CONCLUSIONS
MBC was characterized by larger size at baseline as compared to NMBC. There were no pCR's seen in MBC, but some MBC did achieve response that allowed for breast conservation. Although the average tumor volume reduction was significantly less in MBC compared to NMBC, the NMBC that failed to achieve pCR fared much worse than MBC who did not achieve pCR. Therefore, the triple-negative paradox is likely not applicable to MBC.


Data collected from surf waters of Mangalore revealed the time scale variation of hydrographical parameters and phytoplankton community. Salinity and plant nutrients specially nitrate and silicate exhibited a conspicuous fluctuation in relation to intensity of precipitation. Surf water was characterized with much higher levels of limiting nutrients than the Redfield ratio. Diatoms dominated numerically among phytoplankton in the surf waters followed by dinoflagellates and blue green algae. Lower salinity associated with high load of nutrients favored the growth of bloom forming centric types of diatoms. While diverse forms of diatoms, dinoflagellates and blue green algae occurred with increasing salinity in surf waters. Shannon's species diversity varied from 0.049 to 2.125 and Shannon's evenness index varied from 0.020 to 0.735. Diversity indices indicated gradual increase in diversity and evenness values in relation to variation of salinity and nutrients.


The anti-corruption campaign should adhere to the principle of "looking into both its root cause and symptoms",merging education,prevention and prosecution into organic whole.But a number of departments and districts attach importance to punishment,while neglect prevention,thereby making it difficult to achieve a lot in the work of against-corruption and for-probity.So it is imperative to lay stress on the function of education,especially of psychological education in the anti-corruption campaign.


The (e,3-1e) four-fold differential cross sections (4DCS) are measured for the electron impact double ionization of rare gas atoms (He, Ne, Ar) in coplanar asymmetric geometry for a wide range of ejected electron energies (5 to 144 eV) and at an incident energy of about 600 – 700 eV. Though we only show here a sample of the results, all experimental angular distributions of the 4DCS are characterized by large angular shifts of the forward and backward lobes with respect to the momentum transfer direction or its opposite, respectively. This validates our previously published results [Lahmam-Bennani et al 2002 J. Phys. B: At. Mol. Opt. Phys. 35 L59] which were questioned by Götz et al [2003 J. Phys. B: At. Mol. Opt. Phys. 36 L77]. A qualitative, kinematical analysis is given which allows relating these shifts and the observed structures (or sub-lobes) in the cross section distributions to the second order, 'two-step 2' double ionization mechanism, which is shown to predominate over the first-order 'shake-off' and 'two-step 1' mechanisms under the present kinematics.

Air-conditioning system is an important component of the building equipment, but also a large energy consumption item of building. The accurate and timely air-conditioning fault diagnosis will guarantee the stable operation of the air-conditioning, which fulfils key functions in construction energy conservation, but now the bottleneck of fault diagnosis technology of air-conditioning is lack of fault samples, therefore, this paper puts forward an air-conditioning fault diagnosis method based on SVM , which can realize the SVM Multi-fault classifier through diagnosis of the typical faults in air conditioning system, it shows that the designed system has good classification accuracy and generalization ability.


The Rack Protection Monitor is a simple, fail-safe device to monitor smoke, temperature and ventilation sensors. It accepts inputs from redundant sensors and has a hardwired algorithm to prevent nuisance power trips due to random sensor failures. When a sensor is triggered the Rack Protection Monitor latches and annunicates the alarm. If another sensor is triggered, the Rack Protection Monitor locally shuts down the power to the relay rack and sends alarm to central control.


A novel work on several aspects of current conduction mechanism for resistive switching (RS) of a reactive electrode-based memristor (Al/ZnO/Al) against generally used inert electrode–based devices has been illustrated. Compliance current (Icc), i.e. maximum current through device and stop voltage (Vstop), i.e. maximum Vstop upon device, has been used as bias characteristics to evaluate the effect upon conduction behavior. Effect of change in Icc for constant Vstop and vice-versa upon high resistance state (HRS) and low resistance state (LRS) has been evaluated in terms of change in bulk defects, i.e. oxygen vacancy and interface inhomogenity, i.e. AlOx formation/dissolution. The device shows unipolar resistive switching (URS) at lower Icc (< = 0.1 mA) and transits irreversibly into bipolar resistive switching (BRS) at higher Icc (> = 1 mA). The dominant conduction behavior of the device is found to be homogenous resistive switching (HoRS). The conduction in HRS and LRS is found to be space-charge limited current conduction. Conductive atomic force microscopy results of the thin film switching layer support the HoRS mechanism and also illustrate the role of interfacial oxide in attributing BRS behavior in the Al/ZnO/Al resistive switch. Studies can be utilized in future to further understand the RS conduction mechanism in reactive electrode–based RS and can be applied for multi-state memory applications.


"This research was motivated from a need to understand the buckling behaviour of laminated composites in structures such as aircraft fuselages and body-skin of automobiles or ships with various inplane loads and supporting mechanisms"


Work readiness has been discussed in the literature since the 1980s as economic difficulties and increasing competitiveness of global markets led American manufacturers to reconsider roles, responsibilities, and skills needed of workers (O'Neil, Allred, & Baker, 1992;U. S. Department of Education, 1983). Assessing the work readiness of high school students is important because they tend to be employed in entry–level jobs after graduation and increasingly these jobs require higher skills and knowledge than students may possess (Alvarez, Gillies, & Bradsher, 2003;Lippman & Keith, 2009;National Governors Association, 2010). This skills differential is important to career technical education (CTE) because CTE has been at the forefront of providing workplace skills training in secondary and postsecondary schools throughout the past century (Scott & Sarkees–Wircenski, 2008).


The concept of historic range of variability (HRV) is briefly evaluated within the context of its application in ecosystem management over the past two decades. Despite caveats to the contrary, an implicit assumption continues to emerge of climatic stationarity, and, by corollary, that presettlement centuries provide an appropriate reference period. This is examined from the perspective of historic climate change and ecosystem response. As a means of developing reference prescriptions and management targets, HRV is generally inappropriate, although if historic periods are used for reconstruction that have coarse resemblance to present or projected future climates, such as the Medieval Climate Anomaly or middle Holocene rather than the presettlement centuries, these might be defensible. In cases of reclamation of severely degraded ecosystems, HRV prescriptions developed from analogous climate periods could provide coarse guides. In most situations, however, historic reconstructions are best used to improve understanding of ecological response to a wide range of forcing factors, and thereby to inform (rather than prescribe) management strategies. Such historically informed approaches are likely more effective than an HRV approach under future changing climate regimes for managing and restoring ecosystem function and for assisting transitions to new ecosystem states.

ABSTRACT The paper presents comparison between the punching shear calculations from six different codes and two equations from the literature. It utilizes 257 punching tests data collected from the literature. The concrete strengths, f'c, range between 12.3 MPa and 68 MPa, the reinforcement ratios range between 0.2% and 5.01%, and the slab depths range between 80 mm and 500 mm. It is found that the smallest error is for CEB-FIP-90 and EC2-2004 while the largest error is for JSCE-2002 and ACI318-19. Also, modifications to one of the equations of the Egyptian reinforced concrete code and two of the equations of ACI318-19 code for calculating the punching strength of flat plates without shear reinforcements are presented. The modified Egyptian and ACI318-19 codes equations for punching strength are compared to the experimental data and good correlations are noticed. The obtained errors are lesser than those of the original codes equations and the average errors are on the conservative side.


Aiming at the problem that the common algorithm often suffers high-complex computation problem, this paper presents an improved association rule algorithm based on vector method, which can map the database into a Boolean matrix by scanning the database only one time. Meanwhile, the frequent itemset can be generated by using simple vector operation. As a result, the number of the frequent items generated by using proposed approach decreases sharply. Experimental results on coronary heart disease data set, including comparisons with the common Apriori approach, illustrate the effectiveness of the proposed algorithm.


Vulvodynia, defined as chronic vulvar pain of uncertain etiology, affects as many as 4% of women. To learn more about this condition, investigators at one health care center conducted a survey of 77 women with vulvodynia and of 208 asymptomatic controls. The women were primarily white …


The aim of this exploratory study was to verify the adhesion of participants in combat sport in six years of project activity. Compare the adherence of combat sports practitioners with practitioners of other activities in PIS. In six years of the PIS were found 6,932 registration forms, relating to 5,462 students of both sexes, aged from 5 to 24 years. Data were quantified for subsequent triangulation and interpretation. In six years of existence of PIS, 79.4% of registered abandoned operations in the first year of practice - 16% remained up to 2 years; 3.2% up to 3 years; 1.1 to 4 years; 0.3% remained under 6 years. One hypothesis for the adherence of combat sports practitioners may be the targets and ratings established in the graduation criteria. As the tradition of fight, different band levels establish criteria that allow students to see their progress and request a systematization of the teaching process which involves developing skills and knowledge.


In this paper, we compare two potential 5G wireless technologies, ATTO-cell and massive MIMO, from a human EM-exposure point of view. A scenario, which allows one to make such comparison, was proposed. A set of finite-difference time-domain simulations was performed in order to estimate an average worst-case specific absorption rate in both cases. It was shown that starting at a certain distance from a massive MIMO base station, its exposure becomes lower than exposure by ATTO-cells.


The importance of assuming and facilitating the pain and death process, as well as the way of facing up to it, it is something that always exists in the individual. Therefore, it may be interesting going into the population attitudes before those processes in depth. The goal of this essay has been to get to know the preferences in individuals about how they want to be treated before a terminal illness with pain process and which factors affect those preferences.


Foot-and-mouth disease (FMD) is a highly contagious viral disease of economic importance affecting cloven footed animals as well as more than 70 wild species including elephant. A natural case of FMD in a captive Indian elephant (Elephas maximus) was recorded in the year 2013. The FMD virus (FMDV) was isolated from the clinical sample in BHK-21 cell culture and found to be serotype O. Genetic analysis revealed that the grouping of the isolate from the affected elephant was within Ind2001 lineage. Further the isolate was found to be in close genetic relationships with contemporary isolates sampled from domestic animals in nearby areas. Herewith we provide the direct evidence for virus transmission from the infected domestic animal to captive elephant during the height of FMD outbreak.


Congenital heart disease (CHD) is a congenital condition caused by a lack of heart development during the fetal stage. There is a notion that children with CHD have low nutritional status due to their condition. Nutritional input, energy requirements, dietary components, and prenatal circumstances impact a person's nutritional status.
An analytical observational design with a cross-sectional approach was used in this research. Data were obtained via medical records and questionnaires posed to the patients' guardians who had provided informed consent. The Chi-square test and multivariate logistic regression analysis were used to analyze the data.
The study was conducted on 62 subjects. There were 74.19% of subjects with acyanotic CHD and 25.81% with cyanotic CHD. 61.29 % of the subjects were exclusively breastfed for the first six months. The Chi-Square test revealed a relationship between breastfeeding and the nutritional status of children with CHD, with p = 0.0001 (p<0.05).
The multivariate logistic regression analysis showed the significance of the type of CHD suffered by the subjects was 0.003 (p<0.05).
There is a significant association between breastfeeding for the first six months and the type of CHD suffered by children with their nutritional status at Dr. Soetomo General Hospital.


Introduction: Somatostatin receptors expressed on a wide range of human tumors, are potential targets for the peptide receptor radionuclide therapy (PRRT). In this study, 177Lu-[DOTA-DPhe1, Tyr3]octreotide (177Lu-DOTATOC) as an agent for PRRT was prepared and its biodistribution was studied in rats.
Methods:The best condition for the preparation of the 177Lu-DOTATOC radiolabeled complex was determined by various experiments. Radiochemical purity of the radiolabeled complex was checked using ITLC method. The stability of the complex in room temperature and in human serum was studied up to 48 h. The biodistribution of 177Lu-DOTATOC solution was investigated in male rats at each selected interval time (2, 4, 24, 48, 72 and 168 h) after injection and compared with the biodistribution of 177LuCl3 solution in the same-type rats.
Results:177Lu-DOTATOC was prepared successfully with radiochemical purity of higher than 99% in 30 min at the optimized conditions. The stability of the radiolabeled complex at room temperature and in human serum at 37 °C showed no decrease in the radiochemical purity even after for 48 h. The biological behavior of the complex showed a major difference uptake with 177LuCl3 solution especially in the liver and spleen and also in somatostatin receptor-positive tissues such as pancreas and adrenal.

Conclusion: The results showed that 177Lu-DOTATOC has the comparable pharmacokinetic with the other DOTATOC complexes, while has completely different pattern compared with 177Lu cation.


Nowadays, programming courses are based on the Learning by Doing, where students interactively code, and programming judges automatically assess their codes against testcases. Although the use of students computers is common for both formative and long summative assessments, many short summative assessments (e.g., exams) still rely on institution computers to avoid plagiarism. The number of computers and access to internet necessary for massive courses makes this an inapplicable option for lots of institutions. This works presents OSTIA (Offline System for Testcase Interactive Assessments), a low cost alternative based on the students computers, without requiring internet, but guaranteeing that the assessment is done individually. The system involves a pendrive-based operating system, containing an offline programming judge and testcases. It allows the student to program interactively and assess their codes locally, restricting the access to other resources. The grades are collected using QR codes and an offline mobile app.


There has been increasing application of solar when combined with shared land use. Current examples are PV systems floating on water, and also dual-use land where agriculture is interwoven with PV panels. There are clearly challenges with these types of implementations in that either the geography makes the installation more difficult, or the activity requires a need to share both the land and the light "harvesting" of photons. Because of these challenges, it is necessary to optimize the implementation of the PV and other land-use to extract meaningful value beyond just a demonstration project. But the diversity and complexity of the configurations do not lend themselves to simple analysis. Given this complexity, it is necessary to develop flexible algorithms which can take multiple variables into account where the data may be from multiple complex sources. This is the very configuration where Advanced Neural Net applications can assist and guide the installation and management of the combined land-use activities.This paper will describe the following: (1) the key advantages of AI/ML, along with the current issues, (2) the need for transferrable algorithms development, and (3) the overall methodology for implementation and extension to the broader PV dual-land use segment. Specific data will be presented on the novel AI/ML proposed. A key attribute with this novel AI/ML is one can scale and transfer the template developed without re-customization. The key point of the paper is that – as with any niche application of PV and especially in a dual-use mode, there are substantial challenges which must be overcome, and the use of AI/ML will be a useful tool to exploit the advantages and elevate the application to a more broadly used mode of PV.


Abstract This article primarily focuses on how one social studies teacher education faculty member incorporated technology into a series of social studies education courses. The integration involved both a technology-related project for students to complete and the modeling of technology use to facilitate learning. The article describes the project and the three forms of modeling that occurred. It then reports on the impact of this integration. Most students reported that the instructor's modeling of methods and resources encouraged them to use technology in their teaching. Evidence in students' microteaching, discussions, coursework, and classroom teaching support their statements.


Chymotrypsin, like most other enzymes with esterase activity, is inactivated by combination with organophosphates (Balls & Jansen, 1952). The inactive phosphorylated enzyme is relatively stable in water but hydroxylamine and picolinohydroxamic acid will restore the activity by nucleophilic displacement of the enzyme from the phosphoryl residue (Cunningham, 1954; Jandorf, Crowell & Levin, 1955). The only reported kinetic study of this process is by Cunningham (1954) on reactivation with hydroxylamine, but his conclusions as to mechanism are open to criticism as, at best, only about 30% of the original enzymic activity could be recovered. The present paper describes the complete reactivation of phosphorylated chymotrypsin by oximes and hydroxamic acids. The results necessitate some modification of views on the mechanisms for chymotryptic hydrolysis which have been proposed recently (Cunningham, 1957; Dixon & Neurath, 1957a; Davies & Green, 1958).
