The piano, as the king of playing instruments, is the most popular instrument for people to learn to play. Learning to play the piano, on the other hand, necessitates professional instruction and a lot of practice. People do not have enough time for systematic training because of the fast pace of life. At the same time, a lack of professional piano teachers and high tuition fees discourage piano students. If the computer can recognize and evaluate the learner's piano music in real time, the learner will be able to identify and correct errors in real time. There are currently some music recognition technologies, but the majority of them have the following flaws: first and foremost, the recognition accuracy is poor. Second, the identification process is slow and not real-time. Based on the existing problems, this paper proposes a mobile-based music recognition method. The main work of this paper is as follows: (1) a deep neural network (DNN) is applied to the recognition of piano playing music. The use of deep learning models improves the accuracy of music recognition. (2) In order to make the identification of music easier to use, a mobile application is developed in this paper. The app can be installed on mobile phones and tablets. It can input songs in real-time or offline, outputting misplayed notes and scoring the entire composition. In order to evaluate the effect of this study on music recognition, the experimental part uses multiple models for comparison. The experimental results show that the research in this paper is feasible and effective.

The article discusses the problem of mythologism of the threshold of a new epoch in A. Blok's and A. Bely's early lyrics. The younger symbolists' rapprochement of world outlook with a mythological vision of the world is stated, which is most clearly manifested in Blok's and Bely's lyrics at the beginning of the 20th century. Particular attention is paid to the images of dawn and sunset. Consideration of these images in the context of the theme of the end and beginning of the centuries allows us to draw clear parallels in the poetics of "Verses about the Beautiful Lady" and "Gold in Azure". Using the comparative analysis, individual features of mythologizing the arrival of the new century in A. Blok's and A. Bely's poetry are also illustrated. In particular, the eschatological motifs inherent in the verses of Bely's "Gold in Azure" and, in general, absent in Blok's "Verses about the Beautiful Lady" are emphasized. This explains the different connotations of the image of sunset in the early lyrics of the two poets.


In order to improve the accuracy of classification problem in intrusion detection, a hybrid classifier which was composed by KPCA, RBFNN and PSO, has been proposed in this paper. In the hybrid classifier, KPCA was used to reduce the dimensions, RBF was the core classification, and then PSO was used to optimize the parameters for EBFNN. The hybrid classifier used KPCA to extract the core nonlinear characteristics of raw data, introducing PSO to seek parameters overcame the weakness of RBFNN such as easily limit to local minimum points, low recognition rate and poor generalization. Finally the paper has done simulation using the KDDCUP99 data set in the matlab environment. Finally, the effectiveness of hybrid classifier was proved by experiments. Compared with traditional methods, the hybrid classifier has significantly improved the accuracy of classification in intrusion detection.


Disseminating Records of the Historian and studying it are two interdependent issues.In the Han Dynasty,it had failed to disseminate widely,mainly due to fetters in politics.And at that time,it was explained only from the perspective of politics.While in the Jin and Tang Dynasties,people overcame the difficulties of economy and technology,longing for knowledge,and made copies of the Records by writing,which contributed to its wider circulation than in the previous dynasty.So with further studying the masterpiece,it gradually made its way of expounding the academic meaning of the book.

To determine the phenolic content and anti-oxidation properties of ginger at different harvesting time and to test its effects on lipid droplet and triglyceride formation, and expression of genes for adipogenesis and lipogenesis in 3T3L1 adipocytes.

 The biweekly ginger samples for 16 weeks were freeze dried and then extracted in 80% Methanol. The total phenolic content was determined using the Folin- Ciocalteu method and analysis of antioxidation activity was determined using 2, 2- Diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azinobis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS•+) chemical assays and 2', 7'-Dichlorodihydrofluorescin diacetate (DCFH-DA cellular method. The ginger samples were analyzed to determine major phytochemicals including gingerol, paradol, and shogaol, using a HPLC system. The effect of baby ginger on lipid droplet formation in 3T3 adipocytes was determined using Oil Red'O staining and concentration of Triglycerides was assayed using a commercial kit. Expression of CREPB1, C/EBPβ, and PPARγ genes for adipogenesis and ACC and PEPCK genes for lipogenesis was determined by qRT-PCR.

 Ginger has the highest content of phenolic compounds and superior anti-oxidation activity when harvested early (baby ginger); however, the concentration of phenolic compounds and its anti-oxidation activity were progressively reduced up to 50% as ginger matures. Furthermore, ginger reduced oil droplet accumulation by 25%-40% in a dose dependent manner, which consequently resulted in 50% inhibition of triglycerides accumulation in the adipocytes. Ginger treatment of 3T3 cells inhibited expression of adipogenesis genes CEBPβ and PPARγ and lipogenesis genes ACC and PEPCK.

 Our results suggest harvesting of ginger at appropriate (early) time to optimize or maintain the qualitative and quantitative levels of biological active compounds. The data also suggest that a regular use of ginger can potentially lower incidences of obesity and obesity-related complications, a growing concern in the USA.

This paper argues that the educational system in the United States has shown little interest in educating African Americans. This lack of interest is most evident in public responses to Black language, which has shown repeatedly that this language and those that use it are subjects of derision. Derision of any culture, particularly of one so integral to the nation's foundation, teaches disrespect for racial and ethnic differences and fosters inequities in a nation and an educational system considered to uphold ideals of equality and equal opportunity. This issue of disrespect and its potential impact on students has too often been eclipsed in debates about definition. What is the linguistic form associated largely but not exclusively with Black people? Can this form be considered a language, a dialect, or is it something else altogether? Can or should it be used in educational settings, and how? Important though these questions may be, they typically overshadow the questions posed here, which I draw from the writer, James Baldwin (1979). Can and should a nation seek to teach a people for whom they have shown consistent disrespect? Can and should a people seek to learn from a nation that has consistently disrespected them?


The characteristics of the Alnico 5 and Alnico 8 magnets prepared by hot pressing have been investigated. The raw materials were in the form of powders of the constituent metals. The mixtures of powders were hot compacted in a vacuum using a hot press with inductive heating. The results indicate that the compressibility of Alnico 5 specimens is better than that of Alnico 8 specimens. The theoretical densities for both of Alnico 5 and Alnico 8 were obtained after hot pressing at 800°C for 15 minutes. The optimum magnetic properties of hot pressed magnets are similar to that of commercial sintered Alnico magnets. It is found that the operating point of hot pressed Alnico magnet can affect their temperature coefficient of open circuit magnetic flux. The absolute value of the temperature coefficient of open circuit magnetic flux for hot pressed Alnico 8 magnet increases with increasing the ratio of length/diameter of the magnet. The temperature coefficient of open circuit magnetic flux becomes positive when the B/H is smaller than 2.5. The Alnico 5 is more stable than Alnico 8 and no irreversible losses are greater than 2.7% for Alnico 5 and 3.9% for Alnico 8 after exposure to 550°C. The irreversible losses of Alnico 8 are greater than that of Alnico 5 for short exposure time, however, are smaller than that of Alnico 5 for long term exposure. The SEM fracture surface micrograph of hot deformed Alnico 5 samples does not demonstrate sign of textured characteristics.


The utility model mainly relates to a pasture grass harvester, particularly a drive connecting and compacting device mechanism of a front-positioned mowing and compacting machine with a toothed chain. The front-positioned mowing and compacting machine with a toothed chain comprises a mowing device (20) which is provided with a toothed chain cutter, a suspension mechanism (10) and a driving system (30).

In this study, we derive an analytical model of an electric potential of a double-gated (DG) fully depleted (FD) junctionless (J-less) transistor by solving the two-dimensional Poisson's equation. On the basis of this two-dimensional electric potential model, subthreshold current and swing can be calculated. Threshold voltage roll-off can also be estimated with analytical forms derived using the above model. The calculated results of electric potential, subthreshold current and threshold voltage roll-off are all in good agreement with the results of technology computer aided design (TCAD) simulation. The model proposed in this paper may help in the development of a compact model for simulation program with integrated circuit emphasis (SPICE) simulation and in providing deeper insights into the characteristics of short-channel J-less transistors.


X-linked hypophosphatemic rickets (XLH) is an X-linked dominant disease caused by mutations in the Phosphate-Regulating Endopeptidase X-Linked (PHEX) gene. Due to its rarity and the wide range of clinical manifestations, management of the disease can be challenging due to several associated clinical implications that may arise during follow-up. The neurological complications associated with XLH are the most severe and often less known, which lead to important comorbidities. With the aim of summarizing the available knowledge on neurosurgical intervention in patients with XLH, we present four emblematic cases with disorders requiring neurosurgical evaluation. Relevant diagnostic delay was seen in two of these cases, with another case demonstrating that complications requiring neurosurgery may be present even in patients with few symptoms. The last case stresses the need for care of adult patients who can present with undiagnosed comorbidities. We also carried out a narrative review on neurosurgical interventions in patients with XLH. Through case reports and a review of the literature, focus is placed on the role of the neurosurgeon in the management of patients with XLH. In fact, neurosurgical intervention can often provide stable outcomes for craniosynostosis and clinical improvement for symptoms related to spinal stenosis. Thus, the neurosurgeon can aid in optimizing management of patients with XLH and should be a member of both adult and pediatric multidisciplinary teams. Lastly, additional studies are needed to determine if the early use of burosumab in infants can help to avoid complications in the long term.


The invention provides a resistor-capacitor reinforcement based memory cell of a static random access memory. The memory cell comprises a latch circuit and a bit selection circuit. The latch circuit is composed of two PMOS transistors P1 and P2, two NMOS transistors N1 and N2, a first resistor-capacitor network and a second resistor-capacitor network; the bit selection circuit is composed of NMOS transistors N5 and N6; the latch circuit forms four storage points X1, X1B, X2 and X2B, and a coupling capacitor C is arranged between one complementary pair of the data storage points. Compared with a traditional 6T structure memory cell, the memory cell is additionally provided with the resistor-capacitor networks and the coupling capacitor. Under the conditions that the original read operation path is not changed and the complexity is not obviously increased, the memory cell is prevented from single event upsets at the cost of a little increment in area, thereby ensuring the correctness of data.


this stage;butthe question of universal applicability is of great interest and gains support from many nurses because of the galloping obsolescence of much of medicine and nursing. It boils down to the nurse's role in this new world of health cure and care-to what extent should she have a primary role, what decisions is she obliged to make and therefore be trained for, how does her deployment in changing clinical situations require increasing delegation? And, of course, is there not a need for nurses trained and educated to different levels of expertise, as occurs in medicine? There are pressures from the Federation for a full tertiary education at least to the diploma level for all professional nurses. That means either that they must all meet the entrance standards of tertiary instutions or that these in-turn must lower standards and make exceptions. It is difficult to believe that the latter can happen. It would result in a very considerable number of highly motivated, dedicated young people without any special academic ability either not being admitted or, if given a place, likely to swell the ranks of academic "drop-outs". In South Australia a careful study quoted by the Partridge Committee Heport" suggests that only 25% of those entering nursing in that State could possibly attain tertiary entrance standards, and one suspects that a similar situation exists in Victoria. Is there a danger of being obsessed with academic standards and academic goals in the health areamaybe in other professions as well-and forgetting that a whole spectrum of skills and aptitudes is required? The latest Tertiary Education Commission Report (February, 1978) 7 shows no enthusiasm for credentialism (the new jargon word for the "upward drift of academic qualifications and of requirements of professional bodies"). Perhaps here is the classical situation which requires further study and research, more pilot studies, good evaluation and, one hopes, an evolution towards a goal which will best be achieved by following a number of pathways. It is probable that there is a proportion-10% or soof nurses who require full tertiary education. Is it not equally necessary that provision should be made for a small minority-as in medicine, science and so on-for a few to proceed to master's degrees or even doctorates of philosophy? The W. K. Kellogg Foundation has already indicated that it will give substantial funds for a Nursing Fellowship Program in North America to provide for a significant number of selected nurses to study at a postgraduate level in nursing and interdisciplinary health science programmes. This could make a major contribution, particularly in increasing the number of nurse educators; these are greatly needed-and it is stated with great emphasis by the Ramsay Report, the Syme-Townsend Report and now the Partridge Committee Report, that many more are required at an appropriate academic level. But one can hope that they are not trained to become teachers of theory only, becoming more and more remote from the patient as they advance steadily up the clinical ladder away from reality and practice. No clinician would dare teach medicine unless actively in practice or his credibility with students would be zero or, worse still, a joke. Finally, there are some basic questions which must be considered before fundamental changes are planned.


The objective of the present study was to investigate activity time of the molossid bats Nyctinomops laticaudatus and Molossus molossus at the same locality, and to test whether activity of one species affects activity of the other. During January 2007-May 2009, we sampled for 15 nights over a stream in southeastern Brazil. Total sampling effort was 166 h and 693 m of nets. Time of capture was transformed into minutes in relation to sunset. First captures of M. molossus occurred just after sunset except for one individual that was captured before sunset. Total activity time of M. molossus ranged from 27 min before sunset to 743 min after sunset. Total activity time of N. laticaudatus ranged from 42 to 675 min after sunset and activity differed significantly between species. Activity of M. molossus was related to time of sunset, as expected based on behavior of other insectivorous species, whereas activity of N. laticaudatus seemed independent of sunset.


We construct a quantitative equilibrium model that accounts for the salient features of the US housing market, namely, the homeownership rate, the average foreclosure rate prior to the crisis and the distribution of home-equity ratios across homeowners. Given this steady state, we examine the consequences of a 3 percent unexpected increase in the supply of housing on house prices and foreclosures. We analyze the impact of the tax code, namely the the fact that the implicit rental income from housing is not taxed and that the mortgage interest payment is tax deductible, for the steady state of the model as well as for the impact of the unanticipated supply shock. We show that the model is able to account for the observed decline in house prices with a modest increase in the cost of new mortgages following the shock (crisis) and predicts a large increase in foreclosures.


Chile made several legal, practical and educational changes to the organ donation and transplant system in recent years, to improve its results. However, studies evaluating these reforms and suggesting further corrections are still pending. Our aim is to assess the new regulations and their reception by both the population and health care providers. Proposals are made to promote the development of a model of Chilean transplantation able to respond to the needs of the population.

 The pathophysiology of hypertrophic cardiomyopathy (HCM) consists of dynamic left ventricular outflow tract obstruction, myocardial ischemia, diastolic dysfunction and mitral regurgitation. Mitral regurgitation may be secondary to left ventricular outflow tract obstruction (LVOTO) or related to primary mitral valve pathologies. Three-dimensional (3D) echocardiography has revolutionized imaging of the mitral valve by allowing real-time direct visualization of the mitral valve leaflets in HCM. 3D echocardiography has been using increasingly to evaluate mitral valve clefts and indentations. The aim of this study is to define the frequency of clefts and indentations, and to determine their contribution to mitral regurgitation in patients who are diagnosed HCM and moderate or severe mitral regurgitation by imaging with 3D echocardiography.

 A total of 74 patients who were diagnosed with HCM in accordance with current guidelines and moderate or severe mitral regurgitation who underwent 3D transesophageal echocardiography (TEE) between Aug 2018 and May 2022 were retrospectively enrolled. In the control group, 200 patients with moderate or severe mitral regurgitation without diagnosis of HCM were selected. Two groups were compared with each other by demographical, echocardiographical features and cardiac magnetic resonance images.

 Our final patient population was a total of 50 patients after exclusion criteria. The number of 24 (48%) was female and the number of 26 (52%) was male. There was 89 female patient (44,5%) and 111 male patient (55,5%) in the control group. Patients who are diagnosed HCM were younger compared with the control group (mean age 54,5 ±14 year for HCM patients versus 61±14 year for control patients). Cleft/indentation was present in 14 (28%) HCM patients versus 31 (15,6%) in control patients. It was determined that cleft/indentation was more prevelant in HCM patients (p = 0,041). When we evaluate the direction of mitral regurgitation jet with the presence of celft/indentation, there was a significant association between anteriorly directed mitral regürgitation jet and the presence of cleft (p = 0,003).

 In this study, the frequency of cleft/indentations in HCM patients was 28%, it means that cleft/indentation is more often in HCM patients according to the patients who have moderate or severe mitral regurgitation without HCM. When the cleft exists, it affects on the direction of mitral regurgitation and leads to anteriorly directed jet. On the other hand, the indentations have no effect on the direction of mitral regurgitation jet. As a result, 3D mitral valve modeling can be helpful to make a differential diagnosis in HCM patients with anteriorly directed mitral regurgitation jet. Morover, there is no significant efficacy in management of mitral regurgitation by using 3D mitral valve modeling to describe indentations solely.


Objective The aim of this study was to observe the association between the development of diabetic retinopathy (DR) in type 2 diabetes mellitus (T2DM) and the levels of glucose and lipid metabolism and serum uric acid (SUA) levels. Methods A retrospective analysis was performed on 97 patients with T2DM who were admitted to our endocrinology department from June 2019 to April 2021 with complete data; the patients were divided into DR and no DR groups (NDR) according to the presence or absence of DR. Their clinical history and biochemical test indexes were collected, and the fundus was examined by fundus photography and the fundoscopic examination method, and the vascular diameter was measured by using a computer software. All clinical data, medical history, and biochemical test indexes were compared between the two groups, and logistic regression was used to analyze the risk factors of DR. Results The duration of DM disease, fasting blood glucose (FBG), glycosylated hemoglobin, type A1C (HbA1c) levels, cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), and SUA levels were higher in the DR group than those in the NDR group, and the differences were significant (P < 0.05). The difference between the NDR group and the DR group in terms of gender, age, BMI, DBP, SBP, family history of DM, FINS, and HDL-C levels was not significant (P > 0.05). The results of multifactorial analysis showed that the four variables of DM duration, HbA1c, TG, and SUA were still risk factors for the development of DR (P < 0.05). Further receiver operating characteristic (ROC) analysis showed that the areas under the curves (AUCs) for the duration of DM disease, HbA1c, TG, and SUA to predict the occurrence of DR were 0.740 (95% CI 0.639–0.841), 0.767 (95% 0.672–0.862), 0.721 (95% CI 0.617–0.826), and 0.693 (95% CI 0.588∼0.797), respectively. Conclusion The lesions of DR in T2DM patients have a close relationship with the course of DM, HbA1c, TG, and SUA, and the course of DM, HbA1c, TG, and SUA has a good predictive value for the occurrence of DR.

Successful product innovation has increasingly been recognized as an outcome of integrating customers into the new product development (NPD) process. In this paper, we explore customer integration by investigating the continual consideration of customer contributions throughout the product innovation process. Through a comparison of the customer integration practices by development contractors with those of in-house developers, we find that the iterative and adaptive innovation process structures of the development contractors facilitate the realization of the full customer contribution potential throughout the product innovation process. We also find additional support for the incorporation of open innovation into an organization's NPD activities. Our findings are based on in-depth case studies of the NPD activities of in-house developers and product development contractors.


The phosphate transport protein from beef heart mitochondria has been purified on a large scale by hydroxylapatite chromatography in the presence of sodium dodecyl sulfate and urea. As shown by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (silver stain), the pure phosphate transport protein preparation consists of two protein bands (a and B, ratio 1:l) with similar mobilities (34 kDa) which display identical peptide maps if fragmented with either CNBr or HCl/dimethyl sulfoxide/HBr. The complete amino acid composition of phosphate transport protein is presented, Quantitative determination of N-terminal amino acids underlines the purity of the preparation and shows for a and B the identical amino-terminals H2N-Ala-Val-Glu-Glu-Glx-Tyr-. Qualitative digestion shows that carboxypeptidase A is able to release at least three amino acids from the C termini of the cy as well as the B band of phosphate transport protein. The nature of these two protein bands is discussed.


This paper provides empirical evidence on the relat ionship between cross-border mergers and acquisitions (M&As) and innovation. For the empiric al analysis a unique firm-level data set is constructed that combines balance sheet data and a merger and acquisitions database with information on patent applications. Within three ye ars after a cross-border M&A, patent applications filed by the merged entity increase by more than 30%. Splitting patent applications by the inventor's country it is found that the positive association with postmerger patenting is mainly driven by patents invent ed in the countries of the acquirers' headquarter and its previous subsidiaries while the re is on average a decrease of patenting applications invented in the targets' country of mo re than 60%. Accounting for endogeneity of international acquisitions by estimating dynamic count data models and applying instrumental variable techniques, the results indic ate that part of this correlation stems from a causal effect. The effects are especially pronounce d in industries with high innovation intensity. 1 RWI. Financial support by the Fritz Thyssen Founda tion is gratefully acknowledged.

Threshold signature is designed to distribute the power of signature,therefore it is more secure than normal single signature.Most of the existing threshold signatrue schemes are provable secure in the random oracle model.An identity-based signature(IBS) is proposed from the bilinear parings based on Paterson's signature scheme In the proposed threshold signatue scheme,a trusted private key generator(PKG) is required to generate and manage the private secret key.The security of the signature scheme is proven in this paper.We show that it is strong and resisted against adapt chosen message attack.


Motor impairment in Parkinson's disease (PD) reflects changes in the basal ganglia‐thalamocortical circuit converging on the primary motor cortex (M1) and supplementary motor area (SMA). Previous studies assessed M1 excitability in PD using transcranial magnetic stimulation (TMS)‐evoked electromyographic activity. TMS‐evoked electroencephalographic activity may unveil broader motor cortical network changes in PD.


The friction-wearing performances of casting ZA27 alloy and tin bronze QSn6.5-0.1 were studied.The results show that ZA27 alloys has a superior wear resistance to that of QSn6.5-0.1 under the same condition,but the wear resistance of spindle base of ZA27 alloy is inferior to that of QSn6.5-0.1.Since the shrinkage porosity formed during solidifying of ZA27 alloy will be filled with oil and powder produced in wearing test,the accuracy of experimental results are influenced.


Photoluminescence (PL) properties of compensated as-grown and air-annealed CuGaSe2 single crystals, grown by the vertical Bridgman technique, in the edge emission spectral region were studied. The intensity maximum of the broad asymmetrical PL band at T= 8 K was found to be at hν max = 1.586 eV. After air annealing at 673 K for 15 min the PL band shifts towards higher energies, and its intensity slightly decreases but the shape remains the same. It is shown that this typical asymmetric PL band is not associated with a certain acceptor level but originates from the bandtail recombination. The valence band tail is formed by the potential fluctuations of charged defects. The average depth of these fluctuations is determined by the Debye-Huckel correlation in the distribution of donors and acceptors. The low-temperature air-annealing reduces the concentration of charged defects, but the sample remains highly compensated.


We extend our recent results concerning norm inequalities on cones to include the case when 0 < p < 1. In this note, we let V be a homogeneous cone in R . V defines a partial ordering in Rn in such a way that x <v y if and only if y x E V. The cone interval (a, b) is thus given by (a, b) = {x E V: a <v x <v b}. For x E V we define Av(x) = f(o,x) dy. Let G(V) denote the automorphism group of V and f: V -+ R+ be a V-homogeneous function of order /.. It is known (see [2, 5]) that if f(x) is not identically 0 then f(x) = c(Av(x))f for all x E V. A *-function on V is a mapping x -+ x* such that x* = -gradlogqv(x), where Xv(x) is the characteristic function of V. We have (see [1, 4]) that (x*)* = x and the Jacobian determinant 1axx*I = cA-2(x), where c is a constant depending on V. Let V* be the dual of V and G( V -+ V*) be the group of linear transforms mapping V onto V*. A homogeneous cone V is called a domain of positivity if there is an S E G(V -+ V*) so that S is symmetric and positive definite. It can be shown (see [4, 5]) that if V is a domain of positivity then x <v Y X Y3* <v* X*.

As Africa was entering the first decade of the new millenniuminto what was euphorically called Africa's century there was a profound sense of hope being frustrated, of stereotypes being reaffirmed, once again, of a country (this time Zimbabwe) embarrassing the African continent. The most common perception about Africa remains that of democratic government under siege, of constitutional governance being undermined, and of the rule oflaw being flagrantly disregarded. This situation presents itself not because of biased media coverage, racial prejudice, the arrogance of Western powers, or an un-African response to a particular problem, but because there is no binding commitment by African leaders to democratic governance and the consequences that flow from such a commitment. Clearly, in Zimbabwe the fundamental principles of democratic governance have been consistently, deliberately, and openly violated (Siabbert, 2000).


. A century has passed since the beginning of the tragic events of the deadly Civil War in Russia in the early twentieth century, which not only dramatically changed the country, but also affected (albeit to a lesser degree) nearly all regions of the world. It is obvious that the debates among historians and scholars of neighboring disciplines on various aspects of the Civil War will not be resolved any time soon, and that many lacunas within this study remain to be filled in. We still lack a consensus on the answers to fundamental questions in the history of the Russian Civil War and its meaning. This work presents the views of Elena Iur ' evna Prokofieva — Candidate of Science (History), Professor in the Russian History and Public Records Department at Belgorod National Research University — regarding several key aspects of the Civil War, including the transformation of the term "civil war" in the context of the traumatic developments of 1917– 1922 (there are also other variants to this chronology), the reasons why the "third force" became insolvent over the course of this acute civil conflict, and the conflict's periodization.

Abstract A convenient method for the preparation of N-Benzyl allylamines is described. Selenophenol generated in catalytic quantities from diphenyldiselenide and sodium borohydride leads to the reductive amination of allylamine by substituted benzaldehydes.


Equine semen used for intracytoplasmic sperm injection (ICSI) is typically frozen-thawed and may be of poor quality. To prepare sperm for ICSI, semen is typically centrifuged to remove freezing extender. However, centrifugation can cause damage to sperm, which is especially meaningful if sperm quality is already poor. We evaluated a method for selection of sperm without centrifugation, using a "swim-over" technique, and assessed the effect of pentoxifylline, a phosphodiesterase inhibitor that increases sperm motility in other species. To mimic poor-quality semen, we thawed frozen semen (1×) and re-froze it three additional times (4×). Aliquots (0.25 µL; 50,000 sperm) of 1× or 4× semen were placed at the bottom of the right leg of an "H," made using 15 µL of medium by tracing a template placed below a Petri dish. The medium used (Hanks' balanced salt solution with 40 mg mL BSA and added lactate and pyruvate) contained different concentrations of pentoxifylline (0, 0.5, 1, 2 or 4 mg mL−1). One µL of medium was removed from the tip of the left arm of the H after 15 and 30 min incubation, and the number of sperm were counted. In a second study, we evaluated the effect of pentoxifylline on sperm motility parameters using computer-assisted sperm motility analysis. After thawing, 1× and 4× semen was washed to remove freezing extender and resuspended in the same medium but with 7 mg mL−1 bovine serum albumin (BSA), containing the different pentoxifylline concentrations. In Study 1, the number of collected sperm did not differ significantly for 1× sperm exposed to 0 to 4 mg mL−1 pentoxifylline (means of 15 to 23 sperm at 15 min, and 18 to 25 sperm at 30 min). Similarly, in 4× frozen semen, there was no significant difference in number of collected sperm between 0 mg mL−1 and 2 or 4 mg mL−1 pentoxifylline concentrations (<1 to 6 at 15 min; 5 to 6 at 30 min). In Study 2, at 0 min, % total motility was significantly higher in 1 and 2 mg mL−1 pentoxifylline than in 0 mg mL−1 for 1× sperm (47.8 ± 1.7 and 49.3 ± 1.9, vs. 32.1 ± 3.9, respectively; P = 0.018) and significantly higher for 1, 2, and 4 mg mL−1 pentoxifylline than for 0 mg mL−1 for 4× sperm (3.9 ± 0.9, 5.7 ± 0.4, and 8.2 ± 0.5, vs. 1.2 ± 0.4; P = 0.0001). Similar results were found at 15 and 30 min for 1×, and at 15 min for 4×. Pentoxifylline at 1 to 4 mg mL−1 significantly increased the percentage of progressive motility in 1× sperm at 30 min (17.8 ± 1.3, 21.8 ± 2.7, and 20.3 ± 1.2, vs. 10.0 ± 0.4; P = 0.002) and, at 4 mg mL−1, increased the percentage of progressive motility in 4× sperm at 0 min (1.43 ± 0.1 vs. 0.2 ± 0.1; P = 0.005) and 15 min (1.4 ± 0.2 vs. 0.1 ± 0.0; P = 0.0001). Exposure of poor-quality semen to pentoxifylline at 4 mg mL−1 improved total and progressive motility but did not increase the recovery of motile sperm in a swim-over collection preparation.

In this paper, we present the wavelength engineering of surface emitting lasers for use in high speed short reach systems, which may include the wavelength expansion, the wavelength integration and the wavelength stabilization based on fully monolithic VCSEL technologies. We have developed highly strained GaInAs/GaAs QW VCSELs emitting at 1.1-1.2 μm band and GaInNAs/GaAs VCSELs at 1.3 μm wavelength. Excellent temperature characteristics have been realized. We extended the emission wavelength of highly strained GaInAs QWs up to 1.2 μm and demonstrated low threshold operations of 1.3 μm GaInNAs lasers grown by MOCVD. We carried out the growth of highly strained GaInAs/GaAs quantum wells on a patterned substrate for realizing multiple wavelength VCSEL arrays in a wide wavelength span. We demonstrated a single-mode multiple-wavelength VCSEL array on a patterned GaAs substrate covering a new wavelength window of 1.1- 1.2 μm. By optimizing a pattern shape, we achieved multiple-wavelength operation with widely and precisely controlled lasing wavelengths. The maximum lasing span is over 190 nm. We proposed and demonstrated a micromachined tunable vertical cavity with a stress control layer, which gives us novel functions including temperature insensitive operation, thermal wavelength tuning, and so on. Either temperature insensitive operation or wide wavelength tuning induced by temperature change can be realized. The temperature insensitive VCSEL based on this technology may be helpful for decreasing the channel spacing in coarse WDM systems. We demonstrated long wavelength GaInAs and GaInNAs VCSELs on GaAs substrates, enabling uncooled operation for high speed data transmission in single-mode fibers. The multiple-wavelength array and wavelength engineering of VCSELs may open up ultra-high capacity short reach systems.


In recent years, it has become commonplace for organizations to deploy their services in a cloud environment. However, as this new computation ecosystem matured, the unique challenges of it also started to emerge. Due to the inherent multiparty, multilayer environment of public clouds, both cloud providers and cloud tenants have limited visibility into the whole system. This limited visibility complicates problems involving multiple parties in a cloud, such as accounting resource usage, resource demand estimation, and security monitoring for cloud providers as well as troubleshooting, virtual resource performance estimation/optimization, and automating service deployment for cloud tenants. In existing cloud platforms, solutions for these problems often require time-consuming and expensive interaction between different parties. Given that resource optimization and cost saving are becoming top priorities not only for cloud providers but also for tenants, resolving this lack of visibility problem is becoming a critical challenge of cloud computing platforms. However, extending visibility is not a simple task since, for security and privacy, cloud platforms were originally designed to reduce interparty visibility. In addition, for cloud providers, it could be prohibitively expensive to support such extended visibility for every single tenant. In this dissertation, we study different aspects related to enhancing visibility in a multitenant cloud environment. In the first part of the dissertation, we present a framework to offer cloud tenants better visibility into the cloud infrastructure for better understanding and troubleshooting, where both cloud providers and tenants may save cloud management costs. In the second part, we focus on the cloud provider's visibility into the tenants' network traffic, and enhance it by adopting a widely used traffic matrix estimation model for ISP networks and addressing two key challenges to apply the model to datacenter networks: the sparse traffic matrix problem and the interior traffic sink/source problem. In the last part, we study unintended ways to enhance visibility of tenants in the cloud infrastructure. We focus on cloud tenants' visibility into the states of the virtual firewalls, which are typically supposed to be unknown to cloud tenants, devise a novel method to monitor the states of firewalls, and exploit them as a side channel into the host machine's infrastructure level activities.

On globalization, capitalism and free trade influence each other's outcome and the hegemonic cultural goods of international cultural trade circulate around the world in an aggressive manner. The present research's point of departure is that cultural identity crisis could arise from the cultural products we consume in our lives. By observing the cultural hegemony of international trade that facilitates the circulation of cultural goods in the market in the context of the expansion of capitalism we can start to understand the plight of relatively weak countries in it. According to some economic theories of cultural trade, for these underpowered countries confronting large-scale capital operations (like Disney or the Hollywood film industry), cultural trade does indeed affect the culture (for example, the way of life and values) and cultural industry development. As a result, there are often controversies related to protectionism or liberalism in international cultural trade strategy. For instance, the United States supports free trade but France and Canada are protectionists and they enter conflict with the former. In recent years, UNESCO released the Convention on Protection and Promotion of Diversity of Cultural Expressions, which favored protectionists in the international trade negotiations and through example made more countries think and consider guard tactics in international trade agreement. This research points out that if we insist on the safe guard of cultural trade in a suitable way, it would help us in the conservation of cultural identity. So the present document, apart from using economic and sociological theory to analyze market competition, also tries to discuss the protectionist stance in cultural safe guard and reviews Taiwan's cultural environment. Preceding this path, the document will be separated into four sections to discuss the following: the concept of globalization and cultural trade, an analysis of the monopoly of cultural trade, the mechanism of international defense and a review of Taiwan's current situation.


Two new species of Phidippus are described, P. xeros from Florida and P. toro from the Chiricahua Mts. of Arizona.


Two different crystalline forms were caused by drawing an unoriented isotactic poly(vinylcyclohexane) film, Form I and Form II, depending on the drawing temperature. Form II was changed into Form I thermally and Form I was converted into Form II by drawing. This reversible phase transformation was followed by dynamical X-ray observation. The X-ray measurements were carried out with an X-ray diffraction system with imaging plates, which was designed to record X-ray diffraction patterns over a series of short time spans while the samples were being heated or drawn. When samples were drawn at temperatures below about 110 °C, Form I was produced, and Form II was formed at higher temperatures. Through dynamical observations with the X-ray diffraction system, it was found that Form I occurred at an early stage of drawing independently of the drawing temperature and that the crystalline form was changed into Form II by further drawing at high temperatures, e.g., 130 °C. Form II was transformed into Form I by heat treatment at temperatures above 248 °C. When the heat-treated sample of Form I was drawn at, e.g., 133 °C, the crystalline form was transformed into Form II. Thus, the transformation of Form II into Form I occurred thermally at temperatures above 248 °C and the inverse transformation was induced by applying the stress at temperatures above about 110 °C.


The invention discloses a method, a device and a system for stopping repeated paging. The method comprises that: when at least two user mobile management controlling entities initiate paging to user equipment at the same time, the UE transmits a service request message to the first user mobile management controlling entity of the two entities; after the first user mobile management controlling entity receives the service request message, a stop paging message is transmitted to other user mobile management controlling entities; and other user mobile management controlling entities which receive the stop paging message stop paging the UE. After the UE transmits the service request message to the first user mobile management controlling entity, the first user mobile management controlling entity transmits the stop paging message to other user mobile management controlling entities, and other user mobile management controlling entities stop repeatedly paging the UE at once after receivingthe message, so the paging quantity of the system is reduced, and the system performance is improved.


Dynamic manipulation of quantum states is essential for realizing compact quantum information systems. Metasurfaces have shown excellent advances in quantum state generations, manipulations, and detections at the nanoscale. However, quantum metasurfaces are mostly static currently.


The purpose of this study was to determine the effects of two proficiency rates on the retention of materials using the Precision Teaching Method. Data were obtained during 3 days of treatment and over four monthly posttests using 120 fourth-grade subjects who were categorized by prior achievement as above average, average, and below average. Both treatments were conducted by teachers in classroom settings. Analyses included ANCOVA, t-test of retention ratio means, and t-test of percentage of correct response means. While the results were mixed, a significant interaction effect indicated that subjects in the average and below-average categories performed significantly better after 3 months when the higher proficiency rate was required. Subjects in the below-average category were found to perform with significantly greater accuracy in the higher proficiency rate treatment.


We report on results of comparative studies of catalytic application of new green catalyst, i. e. cerium(III) supported on weekly acidic cation exchanger resin of polyacrylate typein view of the known catalysts based on cerium(III) chloride (free salt in the heptahydrate form eventually doped by sodium iodide or supported on silica gel) in domino syntheses of 2,3-dihydro-1H-1,5-benzodiazepines and 3,4-dihydropyrimidin-2(1H)-ones. Catalyzed domino synthesis of four model 2,3-dihydro-1H-1,5-benzodiazepines were carried out by the solvent free reaction of o-phenylenediamine with corresponding acyclic or cyclic ketone in molar ratio 1:2:2 at room temperature. Three selected 5-ethoxycarbonyl-4-aryl-3,4-dihydropyrimidin-2(1H)-ones were prepared in catalyzed domino three-component synthesis by reaction of ethyl acetoacetate, corresponding benzaldehyde and urea in molar ratio 1:1:3 under boiling in ethanol. The title products were obtained under studied catalytic conditions in very good yields and their identity was confirmed. It was found that the efficiency of the catalytic systems in the syntheses of title benzodiazepines depend on the electron effect of substituents present in the starting benzaldehydes. To confirm the capability of new catalytic system, the above mentioned domino syntheses were realized also without the catalyst but this setup led usually to worse results. Further, it was found that the cerium(III) cation supported on the resin proved to be at least as effective as other used catalytic systems and it is inexpensive, stable, can be easily recycled and reused. Finally, application of cerium(III) supported on low-cost industrial resin further increases green impact of studied domino syntheses for the both title compound class.

Poor visibility in underwater images is commonly attributed to the presence of impurities and the absorbed light being scattered while travelling through impure water. In this paper, image enhancement and restoration techniques are applied to TURBID image datasets. The TURBID dataset consists of three different types of underwater image conditions where blue solution, milk solution, or chlorophyll solution is added to water. The images undergo Histogram equalization (HE) and are filtered with a Wiener filter for image enhancement and image restoration, respectively. HE as the chosen enhancement method proved that it could enhance the image quality as the water surface can be seen clearer after enhancement by visual inspection. Three Wiener filter classes are chosen as the restoration method to reduce the Mean Square Error (MSE) value and to get high Peak Signal-to-Noise-Ratio (PSNR) with desired SNR value. Finally, these two image processing techniques, enhancement, and restoration are combined and the image quantitative values are compared to show that the image performance can be improved with combined enhancement and restoration techniques. It is found that Class 1 Wiener Filter with Enhance then Restore (ER) method has a value of 0 for MSE which is the lowest compared to other studied methods and has infinity values for PSNR and SNR.

The papers in this session focus on the relationship between insitutional constraints and economic change—in my-view the most important policy issue of the 1980s—and they indicate that the field has moved to questions that have policy as well as historical relevance. The decision to conjoin the three papers—one on the "theory" of institutional change, one on problems during a period of growth, and one on problems during a period of stagnation—indicate how far the discipline has progressed since the "stages" paradigm rooted in the work of the historical school reached fruition with the sweeping canvases of Walt Rostow. Bernard Elbaum and William Lazonick suggest that the nineteenth-century institutions served Britain well during her period of growth but acted as a brake when the economy attempted to adjust to rapidly changing world conditions. David Mitch assesses the productivity of social investment in education during that period of growth, and concludes that it was a wise social decision, but perhaps not so profitable as some might have thought. Finally, Carol Heim examines a case of "poor" market response to changes in economic structure during a period when the British economy was growing slowly, if at all. All three papers represent substantial commitments of intellectual capital, and all show that the investment was not wasted—thus they deserve careful discussion. The work of Elbaum and Lazonick is the most general and, perhaps for that reason, the most provocative. It is based on substantial unreported research, it covers a bevy of important and interesting questions, and it comes to some thought-provoking conclusions. The discussion of Britain during the period of nineteenth-century growth is intelligent and incisive. The conclusions about alleged bias in the British capital market and the timing of the "climactric" are bound to be controversial, but are, I think, correct. What doubts I have arise in the later parts of the paper. It is considered unprofessional for any discussant not to raise a few quibbles, and most of my comments should be viewed in that way. For example, I do not know why oligopoly necessarily leads to stable prices and market shares—I can produce such a model, but it is not the one most frequently adduced to explain business behavior in the British institutional environment. It does appear that British firms were slower to adopt the techniques of modern management, but there were exceptions. In the nineteenth century, Vickers had a corporate structure at least as sophisticated as anything existing in the United States; and the authors themselves cite Unilever and Imperial Chemical Industries at a later date. It would be interesting to discover why these innovations did not spread farther—the authors speak of family ties and the lack of technical education, but both "explanations" seem more symptomatic than causal. Again, they blame British institutions for the effects of foreign tariffs, and in this case I think the authors have chosen the wrong counterfactual. Finally, their most powerful and insightful conclusion concerns the life of the institutional stock. Institutional arrangements, productive at one time, can become inhibiting constraints on growth at another. Still one is left to wonder why, like the stock of physical capital, institutions do not also erode. Perhaps the answer is only the length of the erosion process (by the time they disappear the battle is lost), but the question is important.


Formation of a safety insert, comprises expanding a partly reticulated insert to form a closed cellular structure. Includes placing it in a fluid bath at 110-210 degrees C in a pressurized container at an initial absolute pressure of ≥ 5 bar. The pressure drops to 1 bar during the expansion. The expansion is not limited by the size of the container. Independent claims are included for the following: (a) a cooking apparatus for performing the process, comprises a container with an inlet chamber, a cooking compartment including the fluid bath and an outlet chamber. A device transfers the pressurized fluid alternately between the inlet and outlet chambers; (b) the safety insert for mounting on a wheel rim within a tire is of closed cell foam rubber. At its smallest radial cross section the insert has an intermediate layer forming 5-30% of its thickness. This layer has a lower density than the innermost part of the insert.


We establish that the block-encryption algorithm proposed recently by Jakimoski and Kocarev (see ibid., vol.48, no.2, p.163-169, 2001) is secure against differential and linear attacks.


Heart disease is one of the major causes of death with a rate of 17.9 million per year of which 85% of them are due to heart attack and stroke, with more than 75% of deaths occurring in Third world countries. Lifestyle, lack of exercise, and unhealthy diet are the main reasons why people get heart diseases resulting in them going to the hospital or medical centres for treatment. Risk factors, including hypertension, diabetes, smoking, and excessive consumption of alcohol, are a threat to heart-related disease. This paper describes a diagnostic model constructed using a series of sensitivity analyses over two deep learning algorithms, namely, Recurrent Neural Network (RNN) and Convolutional Neural Network (CNN). The sensitivity analysis is performed on the Number Of Input Layers (NOIL), perturbation over Training Vs Testing ratio, and the number of epochs. Features selected are based on the risk factors of coronary heart disease on the dataset from the database Kaggle. The result of the sensitivity analysis indicates that the RNN model yields an accuracy value of 89.4% when the dataset is split into 80:20, whereas the CNN model yields an accuracy value of 87.9% when the dataset is split into 75:25 to predict whether or not a person would have the disease in ten years. The analysis would help detect and facilitate the diagnosis of coronary heart diseases at an early stage.

A field experiment was conducted to investigate the seasonal abundance of major sucking pests viz., citrus blackfly, Aleurocanthus woglumi Ashby and citrus psyllids, Diaphorina citri Kuwayama on acid lime during September 2017 to August 2018. The influence of weather factors on population fluctuation of sucking pests in acid lime ecosystem was recorded that the occurrence of A. woglumi and D. citri were noticed throughout the study period 35 (1 week of September) to 34 (4 week of August) standard weeks. The population of D. citri attained first peak during 40 standard week (1 week of October) with 17.20 nymphs/ twig and its second peak during 19 standard week (2 week of May) recording 17.40 nymphs/twig. The maximum population of D. citri could be observed during 34 standard week (4 week of August) with 24.50 nymphs /twig. Then the population of A. woglumi gradually increased and reached its first peak during 25 standard week (4 week of June) recording 67.70 nymphs/leaf. The sharp decline in A. woglumi population was noticed from 36 standard week (2 week of September) and again started declining from 26 standard week (5 week of June) to 34 standard week (4 week of August). The correlation studies on the weather parameters with D. citri and A. woglumi population revealed that the maximum and minimum temperatures, relative humidity showed significant positive relationship with D. citri, where as rainfall exhibited non significant relationship with D. citri and A. woglumi. From the multiple linear regression analysis it is evident that among the weather factors, maximum and minimum temperatures, relative humidity had significant positive correlation with D. citri and A. woglumi, while rainfall exhibited non significant association with D. citri in acid lime ecosystem.


PURPOSE: To regulate the position in a lateral direction of a molding part adjacent in a lateral direction in a mutually unrelated state by dividing a material sheet into longitudinal sections between mutual molding parts adjacent in a lateral direction by a cutting device. CONSTITUTION: A blade 44 is inserted corresponding to that preparatory punching is ready to perform to act on the surface corresponding to a lower punching part 43. The molded container part connected to a material tape at a breaking scheduled place after preparatory punching reaches a peripheral punching region being a next work stage and a foil is cooled on the way thereof and, therefore, dimensional contraction is generated according to circumstances. In order to perform accurate peripheral punching, the container part is cut off from the material tape 7 at first by using a breaking punch 51 and pressed to the inside of a lower positioning device 52 at the same time. Peripheral punching is performed by the blade 54 provided in an upper punching tool 53 immediately after positioning. This blade 54 corresponds to the periphery of the container part 53 accurately. Next, the container part is raised by a convensional method to be accumulated on an accumulation region 8 and the remaining tape material is taken up on an outlet side. COPYRIGHT: (C)1991,JPO


Many forms of problems arise in the operation of bulk solids storage and feeding systems. Almost invariably these arise due to the nature of the bulk material, rather than from mechanical consideration. The first step of design is to register the relevant properties of the particular solid, in all the forms it has to be handled. An understanding of the bulk stress systems, balanced with modern technology and equipment practice, then enables reliable plant to be constructed. Storage and feeding installations must however be considered as an integrated system, as variations in the condition of the product through the history of the total flow route may well influence performance. Many forms of hopper and feeder problems are described, including interfacing and discharging characteristics. The advantages and limitations of screw feeders are discussed, including their construction and performance features.


This article presents a review of the current literature on the molecular mechanisms of treatment resistance in glioblastoma. As mounting research continues to explore novel methods of treating glioblastoma, from using organoid models for drug screening to developing novel cellular therapies, it is critical to understand the fundamental molecular landscape that makes glioblastoma difficult to treat. This review explores the means of chemoresistance to the conventional chemotherapy temozolomide. Consideration of DNA repair pathways, p53-mediated apoptosis and autophagy, convergent proliferation pathways, and epigenetic mechanisms demonstrate avenues for the development of sophisticated drug targets and combination treatments. Ultimately, this article highlights each of these mechanisms and presents referential material for future endeavors in organoid-based drug screening.


The research was conducted with the aim of examining the influence of financial literacy, financial knowledge, financial attitudes and personality on financial management behavior. The subjects in this examine were Micro, Small and Medium Enterprises (MSMEs) in Banyumas Regency with a population of 8,542 MSMEs and the sample in this observe was 159 MSMEs. Information were dissected the utilizing validity test, reliability test, descriptive analysis, classical assumption test, and multiple regression test. The study demonstrates that financial literacy, financial knowledge, financial attitudes, and personality traits have a significant and positive impact on financial management behavior. Based on this research, financial management behavior for MSME is very important, MSME must understand how important it is to understand financial literacy, financial knowledge, financial attitudes and personality. Thus, some Banyumas MSMEs have implemented good financial management behaviors and can be an example for other MSMEs.

The relationship between the interannual wintertime variability of the North Atlantic Oscillation (NAO) and tropical heating anomalies is examined using the NCEP–NCAR reanalysis and observation-based sea surface temperature (SST) and precipitation data for the period from 1980 to 2011. The NAO is found to be significantly correlated with the precipitation anomalies in the tropical Indian Ocean and tropical American– Atlantic region, but not with the underlying SST anomalies. The tropical heating impact on the NAO is examined and the evolution process of the influence is explored by numerical experiments using a primitive equation atmospheric model forced by atmospheric heating perturbations. Results from the reanalysis data and numerical experiments suggest that the atmospheric heating in the tropical Indian Ocean appears to be a drivingforcefortheNAOvariability.Theatmosphericresponsetothetropicalheatinginvolvesthecombined effects of Rossby wave dispersion, normal mode instability, and transient eddy feedback. The remote forcing influence on the NAO tends to be organized and achieved by the circumglobal teleconnection pattern. By contrast, the influence of the tropical American–Atlantic heating on the NAO is weak. The linkage between the NAO and the tropical American–Atlantic heating is likely through the anomalously meridional atmo- spheric circulation over the Atlantic Ocean.

The objective of this study was to determine the nuclear dihydrotestosterone (DHT) nuclear receptors content in tissues of normal prostate, benign prostatic hypertrophy (BPH), and prostatic cancer. We also attempted to correlate this with the histological pattern of these tissues. Specimens were obtained from five normal subjects, 24 BPH, and 19 prostatic cancer patients. Nuclear receptors content was determined. All histological sections were reviewed by three independent pathologists. The criteria for the quantitative analysis were the degree of cellularity and the stromal content. The mean receptor content was not significantly different between neoplastic tissue (52.6 fmol/mg protein) and hyperplastic tissue (38.9 fmol/mg protein). The number of binding sites in normal prostatic tissue was 8.5 fmol/mg protein. The correlation between the degree of cellularity and DHT receptors showed no significant difference for both BPH, as well as prostatic cancer.

In this work, we have studied an"exponential form"of spacetime metric: \begin{equation*} ds^2 = -e^{-\frac{2m}{r}}dt^2 +e^{\frac{2m}{r}}dr^2 + e^{\frac{2m}{r}}[r^2 d\theta^2 + r^2 \sin^2\theta d\phi^2] \end{equation*} in some of the viable $f(R)$ gravity models, viz. exponential gravity model, Starobinsky gravity model, Tsujikawa model and Gogoi-Goswami f(R) gravity model. Here we have calculated the parameters including energy density, tangential and radial pressure for these corresponding models of $f(R)$ gravity. Subsequently we have investigated the energy conditions viz. null energy condition(NEC), weak energy condition(WEC) and strong energy condition(SEC) for the considered models. We have also explained the suitable conditions of energy for these models by related plots.


Steep sub-threshold transistors are promising candidates to replace the traditional MOSFETs for sub-threshold leakage reduction. In this paper, we explore the use of Inter-Band Tunnel Field Effect Transistors (TFETs) in SRAMs at ultra low supply voltages. The uni-directional current conducting TFETs limit the viability of 6T SRAM cells. To overcome this limitation, 7T SRAM designs were proposed earlier at the cost of extra silicon area. In this paper, we propose a novel 6T SRAM design using Si-TFETs for reliable operation with low leakage at ultra low voltages. We also demonstrate that a functional 6T TFET SRAM design with comparable stability margins and faster performances at low voltages can be realized using proposed design when compared with the 7T TFET SRAM cell. We achieve a leakage reduction improvement of 700X and 1600X over traditional CMOS SRAM designs at VDD of 0.3V and 0.5V respectively which makes it suitable for use at ultra-low power applications.


The RNA-guided endonuclease Cas9 is a versatile genome editing tool with a broad range of applications from therapeutics to functional annotation of genes. Cas9 creates double-strand breaks (DSBs) at targeted genomic loci complementary to a short RNA guide. However, Cas9 can cleave off-target sites that are not fully complementary to the guide, which poses a major challenge for genome editing. Here, we use structure-guided protein engineering to improve the specificity of Streptococcus pyogenes Cas9 (SpCas9). Using targeted deep sequencing and unbiased whole-genome off-target analysis to assess Cas9-mediated DNA cleavage in human cells, we demonstrate that "enhanced specificity" SpCas9 (eSpCas9) variants reduce off-target effects and maintain robust on-target cleavage. Thus, eSpCas9 could be broadly useful for genome editing applications requiring a high level of specificity. The RNA-guided endonuclease Cas9 from microbial CRISPR-Cas adaptive immune systems is a powerful tool for genome editing in eukaryotic cells (1, 2). However, the nuclease activity of Cas9 can be triggered even when there is imperfect complementarity between the RNA guide sequence and an off-target genomic site, particularly if mismatches Corresponding author: email@example.com. *These authors contributed equally to this work.

A Ku-band 14×14 center-fed linear polarized wideband reflectarray antenna is presented in this paper. A new element, which can reach up to a bandwidth of 33.3%, from 13 GHz-18 GHz, is proposed to extend the bandwidth of the reflectarray. The proposed element consists of a square loop and four folded stubs inside, which is modified from the conventional single-loop element. The sub-wavelength technology is applied to enhance the aperture efficiency. The simulation results show that the 1-dB gain bandwidth is 36.7%, and the bandwidth for aperture efficiency larger than 50% can reach up to 36%. The maximum efficiency is 67.6% occurring at the center frequency of 15 GHz.


The purpose of this study was to examine the cause of taste disorders of denture wearers. In this study, the following experiments were performed using fifty subjects of intact dentition and without taste disorders.After producing the experimental palatal plate, the gustatory responses of primary taste shown by the threshold of judgment were examined with the gustatory test using filter-paper disc. The gustatory test was performed in the following three steps: without the plate, just after insertion of the plate and two weeks after insertion of the plate. The change of the threshold of judgment on the tongue and the soft palate was examined. A questionnaire on the sense of incongruity for the plate was taken. The results were as follows:1. All fifty subjects felt incongruity to the plate just after insertion, but two weeks later, only nine subjects (18%) felt incongruity.2. Just after the plate was inserted, the threshold of judgment became higher than that without the plate.3. In two weeks after insertion of the plate, the threshold of judgment recovered almost to the condition before the inserting the plate.The results suggested that the change of somaesthetic information by wearing the hard palatal plate would give rise to a psychological contrast of taste.


An analytical expression for the condition of existence of limit-cycle behaviour for a class of third-order non-linear control systems with memory-type non-linearity is derived. The criteria for the stability of the limit cycle are also included. A typical example is taken for the purpose of illustrating the method of finding the limit-cycle parameters. The divergent, convergent and semistable equilibrium points on the F(a,b,α,β)/E plane are clearly defined.

It describes how SVM can be used for classification and regression calculation. In addition, it includes the description of the fuzzy logic and the three main defuzzification methods. Examples will be given to show simultaneous use of the two main Support Vector Machine-methods. It ends with the authors' description of the new possibilites for the use of the SVM and fuzzy logic in evaluation of the parameter deviation in the batteries of electric vehicles as well as those of robots.


If in plant secondary metabolites, the presence of pesticides and nutritional balances are the most important determinants of nutritional value of food plants, then organically produced plant foods could be expected to bemore health-promoting than conventional foods. Differences arise in management practices between organic and conventional farming where the former support (a) an activation of the plant defence mechanisms by excluding synthetic plant protection agents, (b) an active soil life where plants and microbes interact, exchanging certain metabolic compounds and (c) a balanced mineral nutrient uptake where excesses of easily available nutrients are avoided.


A number of computational models simulate the grounded learning of units of language in the early learner. But can this initial lexical knowledge be used to acquire complex grammatical notions such as anaphora? We build on earlier work, where we simulate a language learner with perceptual attention and learn, in an unsupervised manner, a set of action models along with the participating agents, and then the corresponding linguistic units (verbs). We consider how this knowledge may be used to bootstrap the learning of anaphora. Given an input video with moving shapes, the system considers human narratives that refer to this scene. The acquired perceptual schemas and their arguments are mapped to the appropriate verbs and nouns in the discourse. We first detect the synonyms of the arguments as the repeated labels used in the constructions referring to a known action scene. After ruling out the synonyms, we find that the anaphora remain as units that are referring to more than one grounded object. We show that both third-person singular and plural anaphors and even a common reciprocal anaphor ("each other") can be discovered. Finally, we show that in situations where the referent is missing altogether (zero anaphora), certain correlations may also be inferred from the regularities in the mapping between perceptual schemas and language.


In this study, the thermal characterisation of dielectric barrier discharge plasma actuation driven by radio frequency (RF) voltage waveform at low pressure is studied. The RF discharge images and voltage–current waveforms are quite different under 3 and 40 kPa. The thermographic method has been proposed for the spatial–temporal temperature field on the actuator surface

. At 3 kPa, the high-temperature region is mainly concentrated on the surface of the high-voltage electrode. Along the spanwise direction, the surface temperature gradually increases until it reaches the maximum at the edge of the electrode and then decreases. Similarly, in the chordwise direction, there also exists the maximum value on the surface of the electrode. After discharge starts, the surface temperature rises rapidly, and subsequently, the increasing slope of temperature curves gradually decreases until thermal equilibrium has been reached at about 100 s. The effects of the pressure, duty cycle, and operating power on the thermal characterisation are also investigated experimentally. At low pressure, the discharge mode is diffuse glow discharge, and the high-temperature region covers the whole electrode. As the pressure increases the surface temperature ascends non-linearly, while the surface temperature is linearly dependent on the duty cycle and operating power.


OBJECTIVE
Thyroid cancer survivors have a high risk of second primary malignancies (SPMs). We aimed to evaluate the site-specific incidence, prognosis, and risk factors for metachronous SPMs following thyroid cancer.

DESIGN
A nationwide cohort study Methods: This study included data from the Korea National Health Insurance Service (between 2002 and 2018). Exposure to diagnostic radiation was defined by the number of computed tomography (CT) and positron emission tomography-CT scans after the index date. A cumulative radioactive iodine (RAI) dose >100 mCi was considered high-dose RAI.

RESULTS
During the median six years of follow-up, among 291,640 patients, 13,083 (4·5%) developed SPMs. Thyroid cancer survivors had a 26% increased risk of SPMs compared with the general population (SIR, 1·26; 95% CI, 1·22-1·29). Furthermore, those with SPMs had a significantly poorer survival rate than those without SPMs (HR, 11·85; 95% CI, 11·21-12·54; p<0·001). Significantly elevated risks were observed in myeloid leukemia and 13 solid cancer sites: lip, salivary gland, small intestine, larynx, lung, mediastinum and pleura, mesothelium, breast, corpus uteri, ovary, prostate, kidney, and bladder. Frequent diagnostic medical radiation exposure and high-dose RAI therapy were independent risk factors for several SPMs, including the cancer of salivary gland, lung, mediastinum and pleura, breast, kidney, and bladder, as well as myeloid leukemia.

CONCLUSIONS
Frequent diagnostic radiation exposure and high-dose RAI therapy are independent risk factors for SPM following thyroid cancer. Clinicians need to consider for minimizing unnecessary diagnostic radiation exposure and administering a high dose RAI only when justified in patients with thyroid cancer.

Design/methodology/approach

Literature review and commentary on this topic that has been addressed by professionals, researchers and practitioners.

Findings

Libraries have learned from business the importance of using not only the business practice of using a vigorous level of data-driven decision-making, but data-driven reporting as well to a public that expects a higher level of scrutiny, clarity and precision. Paired with evidence from those who have benefitted from the library's programs and services most visibly, this combination of data and human-driven anecdotes can serve as the optimum marriage of business and service-based confirmation of library success.

Originality/value

The value in exploring this topic is to make the distinction between libraries whose supporters expect it to be formally managed like a business as opposed to those who suggest that business practices be used in library operations to ensure its mission as a service-based entity is maintained.


The effects of temperature on the growth rate of a twostream free electron laser with planar wiggler magnetic pump have been investigated. The dispersion equation has been derived through the use of continuity, momentum transfer, and Maxwell's equations. In the analysis, only the longitudinal component of the pressure tensor is considered in the electron equation of motion. The characteristics of the dispersion relation along with the growth rate are analyzed numerically. The results show that the growth rate in this system is relatively higher than the conventional FEL; finally we compare our results with other cases, like without beam temperature, and conventional FEL. INTRODUCTION The free electron laser (FEL) is a device that generates coherent electromagnetic radiation using relativistic electron beams as an energy source. This is a tunable, high power radiation source. Since, the radiation wavelength varies with electron energy and wiggler wavelength, it can be continuously tuned in frequency [1]. The two principle type of scattering process which occur in FEL experiments are wave-particle (Compton) and wave-wave (Raman) scattering [2]. In the last type the beam-plasma frequency is sufficiently high so that the coupling between the electromagnetic wave and the two beam wave, i.e. negative and positive energy modes can be considered independently. Two stream FEL amplifiers and multiple-beam FEL have been proposed and investigated during the last decades [3-10], Kulish, Jacob and Bekefi, Mehdian et.al, and also Mc Niel, have been presented an investigation of TSFEL. Two parallel electron beams with different relativistic velocities support unstable, exponentially growing space-charge waves over a wide frequency range. Organizing the manuscript is as follow: a leaner theory of the two-stream FEL with planer wiggler magnetic pump is presented and investigated. In section II, fundamental equations presented and employ the fluid theory we obtain the dispersion relation. In section III, numerical study and discussion is presented, and conclusion is given in last section. LINEAR THEORY AND STABILITYANALYSIS In this system, consider a transversely homogeneous, nonneutralized relativistic two electron beams with different relativistic velocity in the z direction, moving through a spatially uniform, externally imposed static magnetic field is taken to be Where w w k λ π 2 = is the wave number and w λ is the wiggler wave length, w B is constant which measure the strength of the wiggler field, the choice of the linearly polarized wiggler induced longitudinal electron oscillations. To make the longitudinal excursions small compared to the radiation wavelength, and thus minimize the possibility of particle untrapping the wiggler amplitude w B must be chosen so that ( √2) [6]. The orbit equation for an electron is given by 2 Subscript α=1, 2, refer to the different quantity for two streams, c, is the speed of the light, is the longitudinal part of the stress tensor. For simplicity, we have only retained the longitudinal component of the stress tensor in the equation of motion to provide the approximate thermal contribution.

BACKGROUND
Nutritional management for patients with diabetes in China is a significant challenge due to the low supply of registered clinical dietitians. To address this, an artificial intelligence (AI)-based nutritionist program that uses advanced language and image recognition models was created. This program can identify ingredients from images of a patient's meal and offer nutritional guidance and dietary recommendations.

OBJECTIVE
The primary objective of this study is to evaluate the competence of the models that support this program.

METHODS
The potential of an AI nutritionist program for patients with type 2 diabetes mellitus (T2DM) was evaluated through a multistep process. First, a survey was conducted among patients with T2DM and endocrinologists to identify knowledge gaps in dietary practices. ChatGPT and GPT 4.0 were then tested through the Chinese Registered Dietitian Examination to assess their proficiency in providing evidence-based dietary advice. ChatGPT's responses to common questions about medical nutrition therapy were compared with expert responses by professional dietitians to evaluate its proficiency. The model's food recommendations were scrutinized for consistency with expert advice. A deep learning-based image recognition model was developed for food identification at the ingredient level, and its performance was compared with existing models. Finally, a user-friendly app was developed, integrating the capabilities of language and image recognition models to potentially improve care for patients with T2DM.

RESULTS
Most patients (182/206, 88.4%) demanded more immediate and comprehensive nutritional management and education. Both ChatGPT and GPT 4.0 passed the Chinese Registered Dietitian examination. ChatGPT's food recommendations were mainly in line with best practices, except for certain foods like root vegetables and dry beans. Professional dietitians' reviews of ChatGPT's responses to common questions were largely positive, with 162 out of 168 providing favorable reviews. The multilabel image recognition model evaluation showed that the Dino V2 model achieved an average F1 score of 0.825, indicating high accuracy in recognizing ingredients.

CONCLUSIONS
The model evaluations were promising. The AI-based nutritionist program is now ready for a supervised pilot study.


The problem of performing a multiparty computation when more than half of the processors are cooperating Byzantine faults is addressed. It is shown how to compute any Boolean function of n inputs distributively, preserving the privacy of inputs held by nonfaulty processors and ensuring that faulty processors obtain the function value if and only if the nonfaulty processors do. If the nonfaulty processors do not obtain the correct function value, they detect cheating with high probability. The solution is based on a new type of verifiable secret sharing in which the secret is revealed not all at once but in small increments. This process ensures that all processors discover the secret at roughly the same time. The solution assumes the existence of an oblivious transfer protocol and uses broadcast channels. The processors are not required to have equal computing power.<<ETX>>


Katz observes that research "should be part of the creative and policy process, and that the competitive system of broadcasting requires that it be part of that process."


This study builds upon my previous treatment of Melville's Moby-Dick first published as 'Moby-Dick: Encountering the Leviathan of God' in my The Old Testament in Fiction and Film: On Reversing the Hermeneutical Flow (1994). The study continues the three-way dialogue set up within that book, with the biblical text, Melville's novel and cinematic treatments of Moby-Dick being compared and contrasted. In particular, it offers a careful discussion of the most recent full-bodied cinematic adaptation of Melville's classic tale, namely the film by the British director Franc Roddam. This film was released in 1998 and starred Patrick Stewart in the role of Captain Ahab. The article discusses some of the theological emphases within the film, particularly in the fields of biblical hermeneutics and inter textuality. Comparisons are also made between Roddam's film and John Huston's 1956 effort which starred Gregory Peck as Captain Ahab.


The performance of organic light emitting devices is strongly dominated by the cathode materials, because the injection barrier for electrons is largely affected by the electronic properties of the used metal. We report internal photoemission measurements of the barrier height existing between aluminum tris(8-hydroxyquinoline) and different cathode materials. It is shown, that a linear relationship exists between the measured barrier height and the work function of the cathode material. However, the gradient in this phenomenological equation indicates, that the barriers cannot be calculated as usual merely as the difference of the lowest unoccupied molecular orbital of the organic material, and the work function of the cathode, but that surface states play an important role. The barrier height remains unchanged after storage, even though the contact exhibits clearly visible degradation effects and numerous "dark spots."


During January, 1998 an unusual and devastating series of ice storms occurred in eastern Ontario and western Quebec. Many forested areas in both these provinces were seriously damaged and sustained severe structural changes which ranged from loss of limbs to being bent horizontally to the ground. The impact on the forests varied from moderate to severe and was usually a function of tree type, and the local severity of the ice storms. In this paper, an investigation is made into the possibility of using the polarization information for classification of damaged forest areas. Polarimetric synthetic aperture radar (SAR) data were collected over a scene in the Ottawa region with the Department of the Environment Convair-580. Reference point targets were deployed during the flight, and used to calibrate the four measured linear polarizations (HH, VV, HV, and VH) in magnitude and phase. Ground truth data were collected in the field and from a helicopter flight.

N-Allylsulphonamides (4) are readily isomerized in the presence of pentacarbonyliron upon irradiation by u.v. light. N-Prop-2-enyl derivatives (5) are obtained, and further isomerization under suitable conditions leads to N-propylidenesulphonamides (6). The last reaction proceeds by a specific 1,3-proton migration involving an N–H group as shown by isotopic labelling experiments.
