The excessive high ethyl lactate content in Luzhou-flavor Daqu base liquor was a common problem. Ethyl lactate was mainly brought from starter and lactic acid bateria in pits. Then the rapid growth and proliferation of lactic acid bacteria under proper conditions could produce lactic acid through metabolism and further developed into large amount of ethyl lactate by enzyme actions, which finally caused the unbalance of caproic acid and lactic acid. The solutions to decreasing ethyl lactate content included the followings: improvement of Daqu quality, use of aged Daqu, strengthening pit mud culture, improvement of pit mud quality, use of bio-techs to reduce lactic acid content, and strict management of technical operations etc. (Tran. by YUE Yang)


Abstract A theoretical investigation into the mechanics of ultrasonic machining is presented in this paper on the following lines: the material removal in ultrasonic machining is due to the periodic hammering by the cutting tool on the workpiece material through rigid spherical abrasive particles. The dislodging of material from the workpiece during machining is due to brittle fracture. No consideration is given to the cavitation erosion and the removal of the material due to the impinging of the flying abrasive particles which are being projected onto the workpiece material by the vibrating tool. Simulating by the principle of elastic waves propagation, the strain energy density distribution in a brittle half space, when a single rigid abrasive grit gives a single 'half-wave displacement with a cutoff' to it, is ascertained. The fracture profile due to this is found and the material removal rate is calculated. Maintaining the same amplitude of vibration, the static loads at the abrasive workpiece contact...


This work consists of an experimental study to better understand the interference of air block valves in measurements performed by metrological class 'B' velocity water meters. According to ordinance 'Portaria nº 246' from the National Institute of Metrology, Quality and Technology (Inmetro), the analysis was based on three experiments required for the approval of such equipment: Errors measurement, Head loss measurement and Magnetic transmission efficiency test. In order to collect the results an automated bench was developed enabling experiments execution without human intervention. Data acquired showed non-compliance with regulation when the system operated with the device. The conclusion taken by the results indicates that the specific air block valve tested may be a harmful influence on the correct operation of water meters.


This project deals with Power Semiconductor Systems PSS for wireless transmission of electricity to the power of 50~W with regard to the distance and transmission efficiency. We decided to use electromagnetic resonance for electrical energy transmission. For experimental verification, we have wound two coils of identical dimensions. At a given power transmission solutions, we obtain the highest efficiency η = 70% at a distance of 5 cm, where the transmitted power was 48 W.


The dynamic model of N17AK flat vehicles loaded with out-of-gauge goods is founded using multi-rigid-body system dynamics simulation software SIMPACK, and the lateral offset caused by the side rolling vibration is simulated and calculated under different conditions.The meeting conditions between vehicles loaded with out-of-gauge goods with different height and general freight trains on adjacent lines are put forward based on simulation calculation results.Simulation indicates that the lateral offset caused by the side rolling vibration augments with the increase of the running speed of vehicles loaded with out-of-gauge goods under the same line condition.The lateral offset caused by the side rolling vibration augments along with the increase of the distance between the calculation point of the out-of-gauge goods and the rail surface under the same condition as well as the same running speed of out-of-gauge freight trains.The two unfavorable conditions are compared,namely,the vehicles loaded with out-of-gauge goods running on I-level line at the maximum speed of 120 km·h-1 is compared with those running on III-level line at the maximum speed of 70 km·h-1,the lateral offset caused by side rolling vibration of the latter is bigger.


We present GaAs/AlGaAs double quantum well devices that can operate as both electron-hole (e-h) and hole-hole (h-h) bilayers, with separating barriers as narrow as 5 nm or 7.5 nm. With such narrow barriers, in the h-h configuration, we observe signs of magnetic-field-induced exciton condensation in the quantum Hall bilayer regime. In the same devices, we can study the zero-magnetic-field e-h and h-h bilayer states using Coulomb drag. Very strong e-h Coulomb drag resistivity (up to 10% of the single layer resistivity) is observed at liquid helium temperatures, but no definite signs of exciton condensation are seen in this case. Self-consistent calculations of the electron and hole wavefunctions show this might be because the average interlayer separation is larger in the e-h case than the h-h case.


Abstract The complicated nature of the semiconductor manufacturing process requires high precision and thousands of spare parts. Due to the characteristics of high cost, as well as dynamic demand rate for spare parts of semiconductor equipment, spare parts inventory management is always an important issue for the equipment supplier. In this paper, we focus on the case of spare parts with high cost and low usage. Using varying lead times and machine life cycles, a simple model to evaluate the relationship between inventory level and service level is developed and a moving sum method is used to estimate the parameters of the model while only a small set of demand data is available. Then we take Applied Materials Taiwan (AMT), a major semiconductor equipment manufacturer in Taiwan, as an example to demonstrate the estimation of parameters of lead time distribution and parts demand rate and the implementation of the inventory model.

The Food and Drug Administration (FDA) approved nivolumab on May 20, 2021, for the adjuvant treatment of completely resected (negative margins) esophageal or gastroesophageal junction cancer in patients who had residual pathologic disease following chemoradiotherapy (CRT). The approval was based on data from the double-blind CheckMate 577 trial which randomly allocated patients to receive nivolumab or placebo. Disease-free survival (DFS) was the primary endpoint. At the time of the final DFS analysis and the pre-specified interim overall survival (OS) analysis, the estimated median DFS was 22.4 months (95% confidence interval [CI]: 16.6, 34.0) in the nivolumab arm vs. 11.0 months (95% CI: 8.3, 14.3) in the placebo arm, with a hazard ratio (HR) of 0.69 (95% CI: 0.56, 0.85; two-sided p-value= 0.0003). An unblinded review of OS did not indicate a detrimental effect on survival. Adverse reactions occurring in ≥20% of patients receiving nivolumab were fatigue/asthenia, diarrhea, nausea, rash, musculoskeletal pain, and cough. Approval of nivolumab is likely to change the treatment paradigm for the adjuvant treatment of patients with completely resected (negative margins) esophageal or gastroesophageal junction cancer who have residual pathologic disease following CRT based on the study results and favorable risk: benefit of nivolumab administration.

We examined the ˆsh toxicity of slaked lime, a strong alkaline agent that is used in invasive ˆsh eradication operations in drained farm ponds. Lime exposure tests showed no substantial diŠerence in 6-h lethal concentration among the four species used (two invasives and two natives). The addition of pond sediments to the lime water to simulate pond conditions signiˆcantly increased the lethal lime concentration but did not aŠect the lethal pH (~12.0). The sediment-added lethal-concentration lime water kept a high pH value even 2 weeks after preparation, while 50-fold or higher dilutions of the lime water showed a neutral pH value immediately after preparation. Based on these ˆndings, we discuss the piscicidal properties of lime and techniques of applying lime to eradicate invasive ˆsh in farm ponds.

From a"countryside folks" point of view ,Shen Cong wen investigated urban culture and observed urban life with an attitude of extreme discrimination. His urban world was absolutely different from the society in West Hunan Province. His norms of "countryside folk" human nature and value spurred him on a profound criticism and reflection on urban culture and led to his tendency of generalization ,formulization and one sidedness in his urban novels.


In this work the need for specific ATPG targeting Gate Oxide Short (GOS) defects is highlighted. Many works have been done to develop ATPG for resistive shorts considering both external bridges between gates, and intra-gate shorts. We show with some examples that in some cases the detection of all detectable intra-gate bridging faults does not imply covering all detectable GOS defects in the circuit. A commercially available standard gate library is analyzed to demonstrate that this problem may appear in real applications. An ATPG tool oriented to detect GOS defects with I/sub DDQ/ testing is presented. ATPG experiments on a set of benchmark circuits show the efficiency of the proposed tool.


We would like to express our concerns about the current publication system for basic biomedical research and to propose an improved system that takes better advantage of Web technology. In the present system, journal Web sites serve primarily as "mirrors" of paper journals and therefore can publish only a limited number of accepted manuscripts. However, as the output of research increases, existing journals no longer provide sufficient space for the volume of information. The problem is compounded by the culture of "publish in high-profile journals or perish," which makes it difficult for authors who publish in specialized journals to be credited favorably for grant competition, job applications, or promotion ([1][1]).

There are a number of serious consequences to this problem. The direction of research is dictated more and more by publishability in high-profile journals, instead of by strict scientific considerations, while fields not deemed fashionable are facing an increasing shortage of young researchers. Furthermore, because of the unpredictability of the publication process, scientists become increasingly apprehensive about sharing their preliminary findings and interacting with one another openly. The fierce competition for publication in high-profile journals may encourage aggressive behavior and discourage others from staying in academic research.

We believe that modifying the current system may alleviate the above problems. Because of the striking differences in volume and cost, paper journals should be used to complement, rather than duplicate, what is published on the Web. Thus, the new system we propose would consist of a high-capacity Web site for posting peer-reviewed papers. A paper version of the journal would be reserved for the fraction of the Web-published papers that have made the strongest impact.

Editors would continue to solicit reviews and enforce an objective scientific standard. However, in this system, a paper would not be rejected on the basis of judgments of "novelty," "priority," or "descriptiveness." Reports that confirm or challenge previous studies or describe significant negative findings would all be considered for publication. This approach should provide cross-examination of results and help fight against misconduct. The scientific editors would also select from the Web-published papers the outstanding papers for republication in the paper version ([2][2]). With more time and objective parameters ([3][3]), the decision will be influenced less by haggling and more by quality.

In addition, the reviewers' comments and the authors' responses to those comments would be published on the Web, thereby encouraging constructive reviews and providing additional insights for readers. Authors of thoughtful, named reviews may be credited accordingly, as part of their productivity and evidence of stature. The new system may also correct the bias against specialized journals: With a high acceptance rate for Web journals but no guarantee for selection in the paper version, scientists will likely choose journals more rationally during submission and develop a balanced view of the value of different journals.

The problems of publishing in basic biomedical research have already exerted serious negative impacts on scientific interactions and education. It would be highly irresponsible for scientific publishers to fail to correct these problems, and equally irresponsible for the scientific community to allow the situation to deteriorate.

High precision and passive alignment of opto devices is of great important in order to reduce assembling costs in hybrid micro systems. Silicon micromachining is suitable in this aspect since it enables the fabrication of high precision structures. This paper will present both generic results conserning high precision silicon micromachining as well as applications in form of fibre alignment structures and chip mounting with interconnects on a silicon substrate. Firstly, ways of producing 45 degree(s) slanted walls in silicon for light reflection are presented. Secondly, flexible clamping structures for holding opto fibres into v- grooves are discussed, both bulk and surface micromachined. These holding structures facilitate the mounting of optical fibres. Finally, a technique for chip mounting and interconnects on a silicon substrate is presented where chips are placed in etched pits and photo patterned BCB is used as dielectrica.


Goal is to understand the mechanisms of formation of alcohols and other oxygenates from syngas over supported catalysts. Work during this period: BET surface areas and XRD patterns of Cu/ZnO/Al{sub 2}O{sub 3} and Co(5%)/Cu/ZnO/Al{sub 2}O{sub 3} suggest that Co did not change the structure. CO was hydrogenated over 10% Co catalyst. C{sub 2}H{sub 4} additions increased the isopropanol and decreased the methanol production. Blank runs with H{sub 2}/He/CH{sub 3}OH/C{sub 2}H{sub 4} showed that C{sub 2}H{sub 4} does not react with CH{sub 3}OH.

The 'greening' of manufacturing firms has created new markets for environmental producer services. Environmental service providers from industrialised countries are more and more forced to internationalise, often due to the international activities of their client firms or to an insufficient offer of such services in the host countries. While knowledge-intensive services in general face problems entering foreign markets, environmental producer services are particularly confronted with specific non-tariff barriers. The latter are not only related to regulatory frameworks, accreditation problems ('neo-protectionism') or missing cultural skills, but also to specific aspects such as confidence between service provider and client firm.


This paper is a descriptive survey study that aims at investigating the learners' perception of problem-based learning experience in Seminar on ELT Class. Choosing of approach in learning English is very important because it can influence successful language learning. One of appropriate approaches which makes the students be active and productive learners is learner-centered approach (O'Banion (1997, p. 47) as cited in Bista (2000, p. 114), problem-based learning is one of methods from learner-centered approach that is very effective to make the students be active and productive learners because toward this method the students have to solve the problem based on real world so that it can train the students to think critically (Lepinski, 2005, p. 1). The writer gave the students a questionnaire. After distributing that questionnaire, the writer conducted interview. The findings showed that the students can explore their knowledge because toward problem-based learning the students have to search appropriate information to get solution of the problem. The students can increase their skill, such as critical thinking because the students have to think critically to solve the problem based on real world. The students can learn to work together and independently so that the students can share their knowledge. Problem-based learning is one of methods can increase students' critical thinking besides the students can learn collaboratively and independently. Lecturers should choose appropriate method to reach the purpose of learning, particularly in student-centered learning. Key words : learners, perception, problem-based learning


Among the various industry sectors, the financial industry in South Africa (SA) has been one of the early adopters of cloud computing (CC) but they have not fully implemented it because of barriers such as security and privacy, governance issues, inadequate cloud service level agreements (SLAs), vendor lock in, poor vendor transparency, inability to assess risks, confidentiality, integrity and availability. Few guidelines exist to help organizations improve their CC readiness level. This is particularly risky for financial institutions that deal with sensitive customer information as the safety of that information is not guaranteed if a desired readiness level is not attained before implementation. In order to assist financial institutions with this hurdle, this paper proposes a framework that will serve as a tool by which financial institutions can determine and improve their CC readiness. The framework is called "Becoming Cloud Computing Ready" (BCCR) and it would help financial institutions to determine which stage they are with their CC readiness. It will also provide guidelines that will assist financial institutions to improve their level of readiness in order to ensure successful CC adoption. The proposed framework is grounded in both the literature as well as empirical data obtained from interviews with the largest financial institutions in SA.

For reaching temporal resolution of about 1 fs in a time converting chronography of pulsed photon radiation in a range of visible light a new principle in the chronography consisting in simultaneous acceleration and longitudinal modulation of photoelectrons for the shortest time (about 1 ps) and at the moment of their escaping from a photocathode are proposed and considered. Photoelectron camera realizing the new principles and using the gold photocathode for soft-x-ray pulse registration with temporal resolution of 100 fs at the photoelectron bunch population of about 1000 electrons will be also discussed.


AbstractThe instability characteristics associated with different radar-derived mesoscale organization modes are examined using six cool seasons of operational scanning radar data near Portland, Oregon, and operational sounding data from Salem, Oregon. Additionally, several years of Microwave Rain Radar Ka-band vertically pointing radar data from Portland and Merwin, Washington, are used to characterize the nature and occurrence of generating cells and fall streaks. The combination of a new metric, convective-stratiform intermittency, with the classification of radar reflectivity maps into convective and stratiform precipitation types was applied to periods when the freezing level was >1.4-km altitude. This method distinguishes periods with embedded convective within stratiform mesoscale organization from those that were mostly convective or mostly stratiform. Mesoscale organization occurs in a continuum of states with predominantly stratiform structure occurring most frequently. Generating cells in the s...


This paper,by presenting a sample of 254 firms from seven industries,tests the relation between corporate cash reserves and governance mechanism based on the cross-section data of publicly traded corporations in China.Findings show that the factors which affect the corporate cash reserves in developed countries also work on the ones in China.Whereas,these factors have opposite effects on the Chinese corporate cash reserves.On the base of the analysis of this phenomenon,we suggest that the different effects of variables are attributed to the difference of the composing of the cost and lucre of corporate cash reserves.In the perfect market economy,the motives of the precaution and the entrenchment effect of corporate cash reserves are more important to the agents than that to the ones in un-perfect market economy.The corporate managers in China care more about the current on-the-job consumption and prettifying performances through spending the cash reserves as quickly as possible.To sum up,the difference in the use of cash reserves is the major reason for the diverse effects of the agency problem.Furthermore,we show that Dittmar et al(2003)'s conclusion is wrong.The reason for why the corporate cash reserves is higher in poor-shareholder-protection countries than that in better-shareholder-protection countries is that the optimal cash balance under the condition of maximum shareholder's wealth is much lower in better-investor-protection countries.Contrarily,the agency problem diminishes the difference of corporate cash reserves level between the perfect and un-perfect market economy.


Abstract Purpose The present study set out to examine whether low job decision latitude (JDL, i.e., limited work autonomy) and low social support at work are related to a poor subjective prognosis of gainful employment (SPE) among working rehabilitants with asthma. Methods JDL and support were assessed by the Copenhagen Psychosocial Questionnaire. The SPE was measured by a validated three-item scale. Separate logistic regression analyses were conducted for all variables to calculate odds ratios (ORs) with 95% confidence intervals (CIs). Results Among the 221 participants (response rate = 29.3%), those reporting low JDL or low support had more than doubled odds of being unsure that they would be working until retirement age (OR = 2.28; 95% CI = 1.19–4.37; OR = 2.78; 95% CI = 1.43–5.40, respectively) and of considering their work ability permanently at risk due to ill-health (OR = 3.89; 95% CI = 2.03–7.46; OR = 2.05; 95% CI = 1.08–3.90, respectively) compared to those with good working conditions. The associations of JDL or support were weaker with one's consideration to apply for premature pension (OR = 1.54; 95% CI = 0.60–3.98; OR = 2.18; 95% CI = 0.83–5.77, respectively). Additional analyses identified job satisfaction as a possible explanatory factor for the observed relationships. Conclusions Adverse psychosocial working conditions are related to a poor SPE, and low job satisfaction may explain those relationships. Future prospective research is needed to confirm our findings. Implications for rehabilitation Earlier research suggested that asthma increases the risk of disability retirement and thus causes high direct and indirect costs. Prior findings showed that adverse psychosocial working conditions are related to poorer asthma self-management and increased asthma morbidity among rehabilitants with asthma. Consistent with earlier work the present study found that job decision latitude and social support at work are associated with the subjective prognosis of gainful employment among working rehabilitants with asthma. If the reported findings are confirmed by prospective studies, interventions could be developed to improve the working conditions for rehabilitants with asthma and to thereby reduce their risk of disability retirement.


Abstract This paper reviews the existing literature on the combination of metaheuristics with machine learning methods and then introduces the concept of learnheuristics, a novel type of hybrid algorithms. Learnheuristics can be used to solve combinatorial optimization problems with dynamic inputs (COPDIs). In these COPDIs, the problem inputs (elements either located in the objective function or in the constraints set) are not fixed in advance as usual. On the contrary, they might vary in a predictable (non-random) way as the solution is partially built according to some heuristic-based iterative process. For instance, a consumer's willingness to spend on a specific product might change as the availability of this product decreases and its price rises. Thus, these inputs might take different values depending on the current solution configuration. These variations in the inputs might require from a coordination between the learning mechanism and the metaheuristic algorithm: at each iteration, the learning method updates the inputs model used by the metaheuristic.


The channel width dependence of hot carrier reliability on NMOSFETs from 0.4-/spl mu/m to 0.13-/spl mu/m technology has been studied at both I/sub b,peak/ and V/sub g/ = V/sub d/ conditions. Enhanced degradation on narrow width devices happens on most technologies. The I/sub b//I/sub d/ value and vertical electric field are proposed to be the reasons for enhanced degradation on narrow width NMOSFETs.


I developed a dynamic height growth model by using a simplified form of mixed effects modeling and subalpine fir (Abies lasiocarpa [Hook.] Nutt.) stem analysis data. The new dynamic equation uses directly heights at any age to predict consistent heights (e.g., y 2 = f(t 2 ,t 1 ,y 1 ) ⇔ y 1 = f(t 1 ,t 2 ,y 2 )) and f(t 3 ,t 1 ,y 1 ) = f(t 3 ,t 2 ,f(t 2 ,t 1 ,y 1 ))), and therefore constitutes compatible site indexand height models in one common equation. The parametersforthe model were estimated by analysis of fixed and random effects with corrections for first- and second-order serial autocorrelation. The correction for second-order autocorrelation was necessary to assure the model's proper representation of the data and to remove a seeming cross-sectional autocorrelation across different sites/series. Estimating the errors in site indices as random effects eliminated the effects of stochastic predictive variables. The proposed model has outperformed all other base-age specific and base-age invariant models in both the fit to the data and in its behavior during extrapolations. It also outperforms the model (developed on amabilis fir data) that is currently, operationally used for subalpine fir. The new model's advantages are parsimony, mathematical tractability, base-age invariance, and greater consistency in curvatures of the generated height-age trajectories. FOR. Sci. 49(4):539-554.

In order to clarify the insecticidal activities and active compounds of Allamanda cathartica Linn, three insecticidal ingredients were isolated from ethanol extract by bioassay-guided fractionation. The antifeeding activities and insecticidal activities of three compounds against Pieris rapae larvae were tested by leaf disk method. Their chemical structures were identified to be allamandin, allamandicin and allamdin repectively by MS,1H NMR. The AFC50 values of antifeedant of 3 insecticidal compounds against fifth instar larvae of P. rapae were 0.071, 0.045 and 0.103 mg/mL after 48 hours respectively. allamdin showed insecticidal activity against fifth instar larvae of P. rapae and its LC50 value was 0.026 mg/mL, which was superior to positive control toosendanin(0.033 mg/mL). Iridoids may be the main insecticidal ingredients of A. cathartica Linn.


AbstractElder abuse is a pervasive and significant public health issue. The relationship between personality of victims and elder abuse remains unclear in literature. This study aims to examine the association between neuroticism, conscientiousness, and elder abuse. Data were derived from the Population Study of Chinese Elderly (PINE), a community-engaged, population-based epidemiological study of 3,157 US Chinese older adults aged 60 and above in the greater Chicago area. Elder abuse was assessed by a ten-item instrument modified from the Hwalek-Sengstok Elder Abuse Screening Test (H-S/EAST) and the Vulnerability to Abuse Screening Scale (VASS). Subtypes of elder abuse include psychological, physical, financial and sexual abuse, and caregiver neglect. The assessments of neuroticism and conscientiousness were derived from the NEO Five-Factor Inventory. Logistic regression models were used. Higher neuroticism (OR: 1.18, 1.15–1.21) and lower conscientiousness (OR: 0.96, 0.95–0.98) were associated with higher risk of elder abuse. With respect to different forms of elder abuse, higher neuroticism was associated with increased risk of psychological abuse (OR: 1.17, 1.14–1.21), financial exploitation (OR: 1.04, 1.00–1.07), and caregiver neglect (OR: 1.08, 1.05–1.12). Higher conscientiousness was associated with higher risk of financial exploitation (OR: 1.02, 1.00–1.05) and lower risk of caregiver neglect (OR: 0.98, 0.96–1.00). This study added new insights to interventions on elder abuse by testing personality traits of victims. Intervention programs could modulate neuroticism and conscientiousness of elder abuse victims.


INTRODUCTION This article is historical in methodology, descriptive/analytic in focus. It was written to offer a primarily European readership an understanding of the origins, development, structure, and functions of the new Canadian Security Intelligence Service (CSIS). Canadians who are, naturally, more familiar with the history and building of the CSIS will find it somewhat basic. Persons knowledgeable in security intelligence affairs will find little new or exciting in it. Yet, it is important that this case study of how a democratic state faced a scandal in its security intelligence functions, and came out of the scandal with a new, legal and democratic security intelligence process, be examined and explained. There are few state systems on earth today which have had the ability and the political will to do what Canada did: to confront an intelligence/security scandal and turn it into a strengthening of democracy.


(Ti0.5, Mg0.5)N thin films were synthesized by reactive dc magnetron sputtering from elemental targets onto c-cut sapphire substrates. Characterization by θ–2θ X-ray diffraction and pole figure measurements shows a rock-salt cubic structure with (111)-oriented growth and a twin-domain structure. The films exhibit an electrical resistivity of 150 mΩ·cm, as measured by four-point-probe, and a Seebeck coefficient of −25 µV/K. It is shown that high temperature (~800 °C) annealing in a nitrogen atmosphere leads to the formation of a cubic LiTiO2-type superstructure as seen by high-resolution scanning transmission electron microscopy. The corresponding phase formation is possibly influenced by oxygen contamination present in the as-deposited films resulting in a cubic superstructure. Density functional theory calculations utilizing the generalized gradient approximation (GGA) functionals show that the LiTiO2-type TiMgN2 structure has a 0.07 eV direct bandgap.


On October 25--26, 1988, about 60 people took part in an Advanced Neutron Source (ANS) Safety Workshop, organized in cooperation with the Oak Ridge Operations (ORO) Office of the Department of Energy (DOE) and held in Knoxville, Tennessee. After a plenary session at which ANS Project staff presented status reports on the ANS design, research and development (R and D), and safety analysis efforts, the workshop broke into three working groups, each covering a different topic: Environmental and Waste Management, Applicable Regulatory Safety Criteria and Goals, and Reactor Concepts. Each group was asked to review the Project's approach to safety-related issues and to provide guidance on future reactor safety needs or directions for the Project. With the help of able chairmen, assisted by reporters and secretarial support, the working groups were extremely successful. Draft reports from each group were prepared before the workshop closed, and the major findings of each group were presented for review and discussion by the entire workshop attendance. This report contains the final version of the group reports, incorporating the results of the overall review by all the workshop participants.


Dalai Lama has been taking up the illegal activities of Tibet independence and splitting the country after he escaped to the foreign countries in 1959.In order to give his illegal activities so-called legal excuses,Dalai outspread his various ideas such as "Tibet was an ancient independent kingdom";"Mongolian and Man ethnics are not belonging to China";"on relationship between the giver and the provider" and "on independence of Tibet in the stage of the Democratic China",etc.at all possible chances.This essay is to repute his wrong ideas by analyzing the main developing history of Tibet before the establishment of the People's Republic of China.

In 2008, in the pages of this journal, Isabelle Macgregor laid out several factors for the somewhat surprising political "swing to the Right" of Australian Jews, including Zionism, the growth of Orthodox Judaism, and Jews' upward social mobility. Macgregor noted that unlike Australia and Britain, America's Jews "have experienced no such transition." Unlike other Americans who have achieved socioeconomic success, Jews remain solid supporters of the Democratic Party. Macgregor writes, "Jews are now the wealthiest ethno-religious American group and also the most consistently liberal" (2008:91). Or, as the American Jewish intellectual Milton Himmelfarb bluntly put it, Jews "earn like Episcopalians and vote like Puerto Ricans." Norman Podhoretz, one of the original "neo-conservatives" who served as the editor of Commentary magazine from 1960 to 1995, wholeheartedly agrees with Macgregor's statement that American Jews have experienced "no such transition" to the Right. In Why are Jews Liberal?--whose title might have included three or four question marks and some exclamation points--Podhoretz sets out to explain the attraction even obsession--of American Jews to liberalism, a phenomenon that Irving Kristol, the "godfather" of neo-conservatism, called the "political stupidity of the Jews": Why do American Jews, who are overwhelmingly middle-class, vote against their economic interests by supporting higher taxes and the welfare state? Why do American Jews time and again misplace their faith in the democratic Left and fail to see that the Religious Right is the staunchest supporter of Israel in the world? And why are Jews so afraid that the first thing Republicans will do in office is implement prayer in schools? The book is divided into two parts. In Part One, "How the Jews Became Liberals," Podhoretz offers a hurried overview of Jewish history since the time Saul became Paul. Part Two, "Why the Jews Are still Liberals," is part-history, part-memoir of Podhoretz's political journey in the second half of the twentieth century. Needless to say, the latter is far more interesting. Readers with any knowledge of Jewish history will be able to skip the historical section of the book, which covers nearly two thousand years in just over 100 pages. Podhoretz's main point in recapping Jewish history in this section is to argue that Jews were welcomed into society by those on the Left and that more often than not the reactionary voices against Jewish toleration were from the Right. Thus--and despite their ignorance or denial of the price exacted for their acceptance--Jews came to be liberals. Beginning with the last three chapters of Part One and in Part Two--the stuff of his own life--Podhoretz really reaches his stride. Having established the Jewish propensity to liberalism, he lays out why Jews vote Democratic: "Enter FDR." The inclusion of Jews into the New Deal coalition so solidified the connection between Jews and the four-time president that, as judge and New York politician Jonah J. Goldstein quipped, for Jews there were three velt'n (worlds): die velt (this world), yennervelt (the world to come), un Roosevelt (p. 13). Podhoretz closes the first section by explaining the need for his long historical overview: "The reason Jews had been attracted to the Democratic Party in the first place was that it represented the closest American counterpart to the forces on the Left that had favoured Jewish emancipation in Europe--just as the Republicans seemed to represent an American version of the conservative forces that had opposed equal rights for Jews in the past" (p. 142). If nothing else, the autobiographical trivia in Why Are Jews Liberal make for fascinating dinner party talk. We find out who Podhoretz cast his vote for: Adlai Stevenson in 1952 and 1956, Hubert Humphrey in 1968, nobody in 1992. But the text, which reads simply and briskly, is more than that. …


The emergence of COVID-19 pandemic poses an immense global health challenge. As dental care providers, we are faced with significant responsibilities both to the dental team and our patients to limit exposure to the virus. Due to the nature of our work, the team are at a high risk of contracting the virus and potentially transmitting the virus. One of the prime modes of containing this pandemic is in enforcing effective social distancing. However, as dental care providers, we face the twin challenge of protecting ourselves and our patients from community transmission and at the same time ensuring patients continue to have access to urgent/emergency dental care. This position statement is for the benefit of endodontists and dentists and provides an objective method of streamlining their dental practices based on need and evidence-based disease containment protocols.


Polylactic acid (PLA) is a biodegradable material widely used in biomedical field. In order to improve the performance of pure PLA, 316 L stainless steel content of 10 vol% to 60 vol % was added to the PLA matrix. Powder physical characteristics tester was used to explore the angle of repose, the angle of collapse, the angle of flat plate and compressibility, the integrated thermal analyzer was for detecting thermal properties of PLA/316 L stainless steel composite. The results showed that the angle of repose and angle of collapse of the composite decreases first and then increases with the increase of 316 L stainless steel powder. The angle of flat plate and compressibility was reduced by the addition of steel powders. When the 316 L stainless steel powder content is 50 vol %, the fluidity of the composite is the best. The high melting point of 316 L stainless steel powder increases the melting point temperature of composites. The prepared PLA/316 L composites can be applied to 3D printing technology represented by fused deposition modeling (FDM).


We consider a totally asymmetric simple exclusion on $\mathbb{Z}$ with the step initial condition, under the additional restriction that the first particle cannot cross a deterministally moving wall. We prove that such a wall may induce asymptotic fluctuation distributions of particle positions of the form $$ \mathbb{P}\Big(\sup_{\tau\in \mathbb{R}}\{\textrm{Airy}_2(\tau) -g(\tau)\}\leq S\Big)$$ with arbitrary barrier functions $g$. This is the same class of distributions that arises as one-point asymptotic fluctuations of TASEPs with arbitrary initial conditions. Examples include Tracy-Widom GOE and GUE distributions, as well as a crossover between them, all arising from various particles behind a linearly moving wall. We also prove that if the right-most particle is second class, and a linearly moving wall is shock-inducing, then the asymptotic distribution of the position of the second class particle is a mixture of the uniform distribution on a segment and the atomic measure at its right end.


This study examines a multi-faceted instructional model used in Applied Technologies programs at a medium size community college. The model accelerates students who have not met placement test benchmarks into college level math with the support of multiple strategies utilized in the model, specifically team teaching in the technical and math courses, a learning community structure, weekly tutoring, and a first year experience course. This study examined the impact of the instructional model on student success, specifically course grades and semester-to-semester persistence, and impact on students' personal qualities, specifically mindset, grit, and study skills self-efficacy. Mixed methods research design examined statistical significance in differences in means of course grades, expected and observed rates of persistence, and personal qualities scores at the beginning of the year, midterm, and at the end of the year. Focus groups were utilized to provide student perceptions to enrich the quantitative data. Findings from the study support acceleration of students scoring near placement test benchmarks with team teaching used to support student learning. Findings affirm the important role institutional representatives as well as peers play in academic integration for community college students.


Much of the global economy melted down in 2008. Three nuclear reactors at Japan's Fukushima Daiichi power plant melted down in 2011. This pair of catastrophes, though very different, sprang from the same fundamental cause: a proliferation of complexity and uncertainty in the world, produced largely because of humankind's increasing prowess in science and technology. Before the two disasters occurred, mathematical models that help manage the economic risk of highly leveraged investments, and nuclear reactors that help power the global energy system, were both seen as important contributors to the economic growth that in recent decades has raised standards of living for hundreds of millions around the world. After the meltdowns, the unavoidable question was: "How could we have been so stupid?" Because humanity depends on complex technological systems to survive and thrive, and because this dependence creates ever-expanding domains of uncertainty and unpredictability, an inescapable incoherence lies at the core of modern society. The incoherence ensures a tragic element in the modern world's quest for progress and control, and this tragedy is woven as intricately into the web of human affairs as were the mood swings of the gods into ancient Greek dramas. The key to the modern tragic dilemma is this: Modern market democracies depend on technological advance for the economic growth that undergirds their political stability. But technological advance is also the source of societal and economic disruption that can threaten such stability. This inherent tension plays itself out every several generations in paroxysms of economic decline and social unrest. The rationale for technological advance is clear. According to the functionalist logic of a consumerist, globalized, capitalist system, technological advance is understood to be a key catalyst for wealth creation, especially through boosting economic productivity and adding novelty and value to the economy via new types of processes and products. Thus, governments increasingly have gotten into the act of promoting technological advance. Since World War II, most market democracies have invested directly in research and development, and have sought to develop a portfolio of policy tools—such as intellectual property regimes, technical standard-setting, technology procurement programs, tax incentives, and rules for public-private collaborations—aimed at accelerating technological innovation in the private sector. The global economic downturn has only magnified the political and cultural obsession with innovation as the secret sauce for future growth. But to promote innovation through scientific and technological advance is also to promote social change—often radical social change. Since the Industrial Revolution, spectacular growth in market economies has been powered by wave after wave of technological transformation: textiles and water power; railways and steam power; steel and electrification; automobiles and mass production; and, most recently, information and communication technologies.

In order to investigate the effect of OsAAP1 gene mutation on chalkiness traits of rice endosperm and the microstructure of starch granules in endosperm, we used rice OsAAP1 mutants as experimental materials, with the help of ordinary optical microscopes and scanning electron microscopes, the morphological structure and arrangement of chalkiness traits and starch granules in the endosperm of Zhonghua 11 rice were observed in rice OsAAP1 mutants and controls. The results showed that the chalkiness rate, chalkiness area and chalkiness degree in rice endosperm of the OsAAP1 mutants were significantly increased, and the morphological structure, arrangement and development of chalkiness traits and starch granules were closely related. Compared with the control Zhonghua 11, there were also significant differences in the shape, structure and arrangement of starch granules between chalky rice and non-chalky rice. However, there was no significant difference between the starch granules in the transparent part of chalky rice and non-chalky rice, and the starch granules in the areas with low chalkiness degree developed well. Thus, the OsAAP1 mutation of rice could significantly increase the chalkiness traits of rice endosperm, and have an important impact on the morphology, structure and development of starch granules in its endosperm.

On results a biotesting the presence of toxic properties of water the tests of which were taken away from the superficial sources of water-supply of citiesKharkovand Chuguev, and also artesian mining holes, is set in Izum. It is set that reason of toxic properties of drinking-water can be a presence in it remaining total chlorine.  A coefficient of plural correlation between the expected risk for the health of people and maintenance in the drinking-water of remaining total chlorine is 0,86.


The CHSH no-signalling game studies Bell nonlocality by showcasing a gap between the win rates of classical strategies, quantum-entangled strategies, and no-signalling strategies. Similarly, the CHSH* single-system game explores the advantage of irreversible processes by showcasing a gap between the win rates of classical reversible strategies, quantum reversible strategies, and irreversible strategies. The irreversible process of erasure rules supreme for the CHSH* single-system game, but this erasure advantage does not necessarily extend to every single-system game: We introduce the 32-Game, in which reversibility is irrelevant and only the distinction between classical and quantum operations matters. We showcase our new insight by modifying the CHSH* game to make it erasure-immune, while conserving its quantum advantage. We conclude by the reverse procedure: We tune the 32-Game to make it erasure-vulnerable, and erase its quantum advantage in the process. The take-home message is that, when the size of the single-system is too small for Alice to encode her whole input, quantum advantage and erasure advantage can happen independently.


Bush yam has been underutilized and underrated for long due to its undesirable attributes or traits, hence the commercial and food security potentials of the crop have been downgraded and unexploited. This paper, therefore, explored the Ghanaian bush yam consumers' decisionmaking behaviour towards the crop's cultivar selection and the values they place on its diverse attributes. With the aim of examining consumers' preference and willingness to pay for bush yam, we designed a choice experiment which was implemented through a cross-sectional survey, involving 390 bush yam consumers in the Western-North, Eastern and Central Cocoa Regions of Ghana. We employed Conditional logit to model consumers' preference behaviour for bush yam attributes from the choice experiment and, subsequently, computed their willingness-to-pay for each attribute, following the Lancaster consumer theory, using the ratios of specific product attributes and cost parameter. Our estimates of consumers' preferences for bush yam attribute revealed a highly significant preference for bigger tuber size, no colour change and sweet taste attributes. Age, education, marital status, and years of consumption were found to have influenced consumers' preferences for bush yam attributes. Furthermore, we found that bush yam consumers are willing to pay extra price value for improvement in tuber size, colour change and taste to meet their indicated preferences. We, therefore, recommend that, for breeding programmes to be more effective and sustainable towards developing a commercial cultivar, breeding institutions and policy makers should focus on the preferred attributes as indicated by consumers for a successful future commercialization of bush yam in the country


In 2013, the Ecuadorian Tax Administration officially launched the electronic invoicing system as a strategy to reduce tax evasion in tax returns. These information systems allow for designing better monitoring and auditing tools; consequently, such systems increase the subjective risk perceived by taxpayers, thus increasing their compliance. The aim of this article is to determine the effect that this system had on value-added tax (VAT) returns in the period 2014-2016, using the difference-in-differences (DID) technique. The results show that the increased coverage of the electronic system over time had positive effects on the declaration of sales, purchases, and taxes.


Romania ranks third among the New European member countries in terms of home furniture consumption after Poland and the Czech Republic. Apparent domestic consumption of home furniture amount to about Euro 1 billion. The distribution structure in the home furniture sector in Romania is in continuous evolution. From the point of view of the supply process the main peculiarity is the significant presence of local furniture producers with their own retail networks in the form of chains. The majority of these are medium-sized stores. This Report, produced by CSIL, Centre for Industrial Studies, offers an analysis of home furniture distribution sector in Romania and provides an economic overview of the country; trend for home furniture consumption; breakdown of home furniture sales by distribution channel (specialized furniture distributors (furniture chains, franchising, buying groups, independent furniture retailers), non-specialist distributors (department stores, multistores, hypermarkets, DIY) and others. The analysis of furniture distribution by product/segment covers: upholstered furniture and kitchen furniture. Home furniture imports are broken down by country, geographical area and product (upholstered furniture, kitchen furniture, dining and living room furniture, bedroom furniture, non-upholstered seats and other furniture). Short profiles of major home furniture distributors with analysis of sales performance are also available.


Abstract: Most source coding standards (voice, audio, image and video) use Variable-Length Codes (VLCs) for compression. However, the VLC decoder is very sensitive to transmission errors in the compressed bit-stream. Previous contributions, using a trellis description of the VLC codeword's to perform soft decoding, have been proposed. But the complexity of the trellis technique becomes intractable. In this paper, we propose a soft-input VLC decoding method which is not trellis based. Performance in the case of transmission over an Additive White Gaussian Noise (AWGN) channel is evaluated. Simulation results show that the proposed decoding algorithm exhibit very low complexity and also bit error rate (BER) at output of channel decoder decreases with increase in SNR. We consider the serial concatenation of a VLC with the channel code and perform iterative decoding. Results show that, when concatenated with Low Density Parity Check (LDPC) codes, iterative decoding provides remarkable error correction performance. Experimental results indicate that the proposed method requires less iteration and improves overall system performance. Keywords: JPEG compression, Discrete Cosine Transform (DCT), Huffman encoding, LDPC codes.


This paper presents the design of a Linear Quadratic Regulator (LQR) with Integral action (LQRI) applied to a grid connected wind energy conversion system (WECS) based on squirrel cage induction generator (SCIG) with full-capacity power converter (WECS-SCIG). The controller is used to achieve speed regulation for maximum power extraction from the wind turbine, DC bus voltage regulation and to keep the power factor at unity for the grid-side converter. The model of this latter is set in the d-q rotating reference frame synchronized with phase a of grid voltages while rotor flux oriented vector control is used for the machine-side converter. Knowing that the standard LQR provide essentially proportional gains, the system dynamic is augmented with the integral of the q component of the grid currents, the rotor flux, the DC bus voltage and the generator speed in order to cancel steady-state errors. The WECS-SCIG is controlled as a whole i.e. a multi-input-multi-output (MIMO) system and a fixed PWM at 2.7 kHz is used to generate the gating signals of the two back to back converters. The system is tested for both steady-state and in transient for a sudden variation in wind speed. The simulation results obtained with SimPowerSystems (SPS) and Simulink of Matlab implementation of the controller proved the effectiveness of the control strategy.


The differential chaos shift keying with code index modulation (CIM-DCSK) using Walsh codes can increase the data rate, but error rate performance degrades over practical multipath channel with high delay spread. To tackle this drawback, this paper proposes a parallel CIM-DCSK (PT-CIM-DCSK), where the first time slot is used to transmit the chaotic reference sequence, and the second slot is used to transmit the multiple sequences carrying data bits. In particular, multiple <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula> chaotic sequences are added for data transmission in parallel, and each sequence is modulated by CIM-DCSK with <inline-formula> <tex-math notation="LaTeX">$m_{c}$ </tex-math></inline-formula> bits. By exploiting the quasi-orthogonal characteristics of permuted chaotic signals, the interference between <inline-formula> <tex-math notation="LaTeX">$q$ </tex-math></inline-formula> sequences can be remarkably suppressed. In this way, given the data rate, PT-CIM-DCSK can achieve a larger length of Walsh segment than the CIM-DCSK, since its parallel transmission compensates the rate. In addition, the error performance of the proposed scheme over the multipath Rayleigh fading channel is theoretically analyzed. The theoretical and consistent simulation results demonstrate that the PT-CIM-DCSK can obtain significant performance gains over the conventional CIM-DCSK, and the gain can be up to 5 dB in multipath fading channel with high delay. This is because the larger Walsh segment of PT-CIM-DCSK provides the enhanced robustness against multipath effect. The performance superiority of the proposed scheme is further verified in practical ultra-wideband (UWB) wireless industrial scenarios, which suggests promising for low-cost and low-complexity wireless communication applications.

Sam Shepard moved to England to get away from New York and America and to get into the rock music scene in London. Shepard is a good drummer but his fantasy of arriving in England and "somehow falling into a rock'n'roll band … didn't work." His plays had preceded him courtesy of the LaMama Touring Company and a few isolated productions. In 1969 the Royal Court Upstairs produced Operation Sidewinder; in 1971, the Traverse Theatre in Edinburgh produced Cowboy Mouth and in May of 1972 the Wakefield Tricycle Company produced Red Cross. That July the Open Space presented the first play he had written in England, The Tooth of Crime and at the same time Wakefield Tricycle Company presented Cowboys #2. These productions received a lot of critical attention and the fact that Shepard was in London encouraged other productions and some commissions.

Packaging for wireless integrated circuit (IC) and component designs is currently undergoing a metamorphosis. The need to move large quantities of data at high speeds continues to increase, so device and component manufacturers are continually under pressure to improve technology while simultaneously reducing costs. Communications and digital IC technologies are moving to progressively higher frequencies. A limiting factor in the speed of operation for many wireless components is often the package parasitic effects, and not the IC itself. Packaging parasitic factors (physical, distributed and electromagnetic effects) can limit the frequency response or signal integrity of an otherwise robust circuit design, thereby capping the potential speed of operation. The value of a packaging solution increases as the frequency of operation increases. It becomes an increasingly dominant factor for product success at frequencies above 2 GHz. The package also becomes an increasingly dominant cost component at higher frequencies. Failure to obtain a packaging solution that meets both performance and cost criteria can contribute to late product introduction or even total market failure. The value of packaging is particularly evident to commercial-volume microwave component manufacturers, who frequently find that packaging costs are prohibitively expensive for their applications. Often locked in competitive struggles, these companies see effective packaging that leverages standard manufacturing processes as a means of significantly reducing the cost of their radios and communications equipment. Wireless applications are not the only area where high-frequency packaging can play a key role in the success of products. High-speed logic, bus transmission and fiber communications can reach data rates that exceed 40 Gb/s, dictating a high-frequency, broadband packaging solution.


Adolescence is the transition phase between childhood and adulthood, characterized
by psychological and biological changes, extending from the onset of puberty to the
attainment of physical maturity and adulthood. In our country, it probably starts at 15
years when the preparations for entry into professional courses begin, and not at 11
years as mentioned in text books.
Parenting is a complex activity that includes many specific behaviours that work
individually or together to influence child outcomes. It prepares the child to enter into
the next phase of life. When we compare the conventional role of a to-day's child with
that of yesterday, i.e. two decades back, we find a sea difference. Two decades ago
children were reared in a relatively protected environment and taught to be subservient
to their elders. The male child was expected to acquire modest education and make a
career or else join the family profession. He was to be the bread winner, supposed to
help in family work; and, if need be, take up family responsibilities at an early stage.
The female child was taught to be submissive, tolerant and compliant; to acquire only
minimal education, but to be proficient in domestic work (cooking, tailoring, home
keeping etc.) so that she could adopt the primary role of a home maker. Most children
did not have exposure to co-education. Introversion was encouraged, and mixing with
the opposite sex considered a taboo


The article is devoted to the subsequent development of previously created end-to-end computer programs for simplified strength analysis of statically determinable double-support and cantilevered I-beams. The aim of this development is to give these programs the additional functions to determine linear and angular displacements in beams by using the Mohr method. To this end, analytical dependencies have been established to determine the values of bending moments in the beam sections from the action of single force factors - the force and moment applied at arbitrary points of these beams. Based on these dependencies, an additional computation for determining displacements were made that improved the capacity of the existing programs for calculating beam strengths. The modified programs calculate the Mohr integrals, thereby determining the desired displacements and plotting their changes along the length of the beams. These programs have been successfully tested in a series of calculations of beams of various types and demonstrated its efficiency and effectiveness. The introduction of the modified programs in the educational process will provide students with new opportunities in the formation of their professional skills. The indicated programs will be useful for professional practitioners as a fairly simple calculation tool for solving real technical problems.


Given a set of rectangular items, all of them associated with a profit, and a single bigger rectangular bin, we can ask to find a non-rotational, non-overlapping packing of a selection of these items into the bin to maximize the profit. A detailed description of the (2 + )-approximation algorithm of Jansen and Zhang [8] for the two- dimensional case is given. Furthermore we derive a (16 + )-approximation algorithm for the threedimensional case (which we call cuboid packing) and improve this algorithm in a second step to an approximation ratio of (9 + ). Finally we prove that cuboid packing does not admit an asymptotic PTAS.


The morbidity of adrenalectomy and high incidence of post-adrenalectomy Nelson's syndrome in children with Gushing's disease suggests that alternative methods of treatment would be especially useful in childhood. Two boys (patient 1, 6 9/12; patient 2, 15 yrs) with classic Cushing's disease and no evidence of pituitary adenoma on skull x-ray or pneumoencephalogram failed to respond to cyproheptadine (0.25-0.5 ng/kg). Transsphenoidal pituitary exploration and removal of a pituitary microadenoma induced complete clinical resolution in both patients. Fasting plasma cortisol levels were low (3.8, 6.2 ug/dl), and the response to insulin-induced hypoglycemia was poor (10.4, 7.1 μg/dl) 2-4 months post-operatively. GH response to insulin-induced hypoglycemia returned to normal (pre-1.3 vs. post-26.8 ng/ml), and ACTH levels rose appropriately during hypoglycemia in patient 1. Patient 2 displayed a nocturnal rise in growth hormone (pre-3.6 vs. post-6.7 ng/ml), normal prolactin (13.5 ng/ml) and increased gonadotropins (pre FSH 2.8 LH 2.3 vs. post FSH 12.8 LH 13.2 mIU/ml) associated with progressive sexual maturation. T-4 and T-3 were normal in both patients postoperatively, as were other tests of pituitary function. We suggest that transsphenoidal pituitary exploration should be the initial therapy of choice in childhood Cushing's disease.


Organizational change – be it moderate or radical – is a must for a better future. Situations such as increasing demands of government regulations, growth, competition, technological developments and changing workforce cause organizations to change. Perbadanan Kemajuan Pertanian Negeri Pahang is one of the biggest organizations in Pahang Darul Makmur. Operating for more than 49 years and has more than 116 staff in the organization, the main headquarters need to deliver the right business process not only to external but internal customers as well. Due to the political and economic change recently, it is important for the organization to stay competitive for the future. The present study aims to examine the Business Process Re-engineering (henceforth BPR) warning signs in the process, technology, and organizational structure as well as company performance. A total of 56 responses collected from the respondents were analyzed, and the findings indicated that all the warning signs do not affect the company's performance. The implications of the study are further discussed in the paper.


The greatest revolution that this 21 st century has been witnessing is the information revolution. This revolution has created the socalled "information society". An information society is a society which makes intensive use of information and communication technologies (Menou and Taylor, 2006). Every nation is a part of this information society or network as now the world has become a global village. The speed with which the flow of information takes place in this network with the emergence of ICT is just a mouse click away. Information and communication technologies collectively refer to the technologies, both hardware and software, that enable humans to communicate with one another.


Atractylodes japonica is a perennial herb in Compositae family, which is used for stomach disorders as a traditional Chinese medicine (Guo et al. 2006). In 2013, a leaf spot disease was first observed on plants of A. japonica in a production field of Fushun County, Liaoning Province, China. The disease had a speckled appearance initially. Lesions with grey–white centre and brown margin gradually developed and enlarged. Eventually, infections usually caused yellowing of the leaves and premature defoliation. The causal agent of infection on plants was identified as Paraphoma chrysanthemicola based on morphological and cultural characteristics, pathogenicity tests and phylogenetic analysis. To our knowledge, this is the first report of a leaf spot disease on A. japonica caused by P. chrysanthemicola in China.

We investigate R&D incentive under patent protection with cooperation option. Chowdhury [Economics Letters, 2005, 89(1), 120-126] claims that patent protection may decrease R&D incentive when the tournament effect (TE) is negative. However, We show that patent protection in the presence of R&D cooperation option always increases R&D incentive. In addition, to increase R&D incentive under patent protection, this cooperation option strictly dominates imitation and may also dominate royalty licensing depending on R&D cost, introduced by Mukherjee [Economics Letters, 2006, 93(2), 196-201]. JEL classification: O32, O34, O38


Treatment of guinea pig flanks with very soft X-rays (borderline rays) may stop the uptake of 3H-Tdr during the DNA synthesis phase of epidermal germinative cells. Evidence of increased proliferative activity at any time after the irradiation can only be seen as a symptom of secondary reactive repair processes.

The solidification behavior of bulk hyper-undercooled Fe_(83)B_(17) eutectic alloy has been investigated by employing molten glass slag purification incorporated with cyclical superheating techniques. It has been found that the microstructures vary with undercooling. When undercooling comes to theoretical critical hyper-undercooling 300 K, the solidification microstructure consists of α-Fe and Fe_2B, whereas hyper-undercooling exceeds critical value 386 K, grains are more coarse and the microstructure becomes complete anomalous eutectic, Fe_2B phase disappears, and the metastable phase Fe_3B occurs in the roomtemperature microstructure which is a production of crystal nucleation in alloy melt. A maximum hyper-undercooling of 460 K and the metastable structure are obtained. The reason of microstructure evolution is also discussed.

CASE I.-On June 10th, 1910, I was requested by Dr. Coffin to see a boy 4 years old, at the Manhattan Eye and Ear Hospital, who gav,e a history of having swallowed a pin a few days previously. He was coughing and vomiting frequently; his temperature was 101.6, pulse 150, respiration 36. A. radiogram showed the pin extending from the second rib to the fourth interspace on the right side, the point being up and directed toward the median line. A bronchoscope had been introduced and the pin was seen in the right bronchus, but it could not be grasped with the forceps. I introduced the Killian tube, and upon advancing it into the right bronchus the shank of the pin could be seen, but neither the head nor the point could be brought into view. c\ll -efforts to dislodge the point of the pin were unsuccessful. I then put a Lister hook around the pin, and by rotating it against the end of the tube I succeeded in bending the pin to nearly a right angle. r then grasped it with powerful forceps at the bend, and extracted it through the tube, completely doubled upon itself. The pin was brass, about IIi inches long, with a glass head 74 inch long. Within forty-eight hours after the operation all symptoms had subsided and the patient could be discharged cured. CASE 2.-0n December 16th, 1910, r was requested by Dr. Brewer to see a patient in his service at the Roosevelt Hospital, who gave the following history:


We study some of the unexplored issues in the parallel phone recognition (PPR) system for automatic language identification (LID). We consider three types of scores for LID, namely, the acoustic score, language model score, and the joint acoustic-languagescore. Using each of these scores we formulate three types of classifiers for performing LID: maximum likelihood classifier (MLC), Gaussian classifier (GC) and K - nearest - neighbor classifier (KNNC) and com-pare their performances. We examine the problem of bias in the PPR scores which affects LID performance and interpret the bias and bias-removal methods which improve the classification accuracy of MLC. Among all the different com-binations of scoring methods and classifiers, it is found that MLC with bias-removal performs best for either acoustic or language model score alone; this is closely followed by GC with the joint acoustic - language score.


Web spam is a big problem for search engine users in World Wide Web. They use deceptive techniques to achieve high rankings. Although many researchers have presented the different approach for classification and web spam detection still it is an open issue in computer science. Analyzing and evaluating these websites can be an effective step for discovering and categorizing the features of these websites. There are several methods and algorithms for detecting those websites, such as decision tree algorithm. In this paper, we present a systematic framework based on CHAID algorithm and a modified string matching algorithm (KMP) for extract features and analysis of these websites. We evaluated our model and other methods with a dataset of Alexa Top 500 Global Sites and Bing search engine results in 500 queries.


antedates pregnancy, is a cause of increased perinatal mortality1-3 while the role of gestational diabetes in perinatal mortality remains doubtful.4 Although the multidisciplinary approach to the management of these diabetic pregnant patients remains the key to successful outcome; the obstetrician who has had some exposure to the management of diabetes might occasionally be faced with managing both the pregnancy as well as the diabetes. The aim of this retrospective study was to determine the fetal outcome in diabetic pregnancies over a 2 year period by way of perinatal mortality, and birth weight and to compare these with the non diabetic group in the same hospital population. The average total number of deliveries in the hospital was 3800 per year. A diabetic team consisting of 2 obstetricians exclusively managed these diabetic patients.

Consumers can realize significant cost savings by procuring resources from computational spot markets such as Amazon Elastic Compute Cloud (EC2) Spot Instances. They can take advantage of the price differentials across time slots, regions, and instance types to minimize the total cost of running their applications on the cloud. However, Spot markets are inherently volatile and dynamic, as a consequence of which Spot prices change continuously. As such, prospective bidders can benefit from intelligent insights into the Spot market dynamics that can help them make more informed bidding decisions. To enable this, we propose a descriptive statistics approach for the analysis of Amazon EC2 Spot markets to detect typical pricing patterns including the presence of seasonal components, extremes and trends. We use three statistical measures - the Gini coefficient, the Theil index, and the exponential weighted moving average. We also devise a model for estimating minimum bids such that the Spot instances will run for specified durations with a probability greater than a set value based on different look back periods. Experimental results show that our estimation yields on average a bidding strategy that can reliably secure an instance at least 80% of the time at minimum target guarantee between 50% and 95%.


Each year, thousands of new cancer cases are reported all over the world. Among them, breast, colorectum, lung, nasopharynx and liver cancers are the top 5 cancer cases reported in 2018 in Malaysia (World Health Organization, 2020). In the same year, lung, colorectum, breast, liver and leukaemia cancer were the major death cancer cases in Malaysia. Radiotherapy, chemotherapy, and surgery are commonly used to treat cancer. However, they may cause some serious side effects apart from the common effects such as nausea and vomiting. Thus, more studies were done to search for alternative cancer treatments to reduce or eliminate these side effects. Vitamin E (tocopherol and tocotrienol) is one of the natural ingredients that were studied recently, and the compound was reported to show an anticancer properties. Tocopherol and tocotrienol were further divided into α-, β-, γ- and δ-tocopherol and tocotrienol but not all isomers were extensively studied. Most studies focusing on the examined isomers were in vitro investigations, with a few extending to in vivo studies. Only a few studies have progressed to clinical studies. This review aims to provide comprehensive information of previous studies on isoforms of vitamin E towards cancer studies.


How can we develop understandings about artist-based research that recognise what we do as valid forms of inquiry with relevant sets of criteria, standards, epistemologies and methodologies?

Research refers to finding out. It is inquiry in its most rigorous form. Practitioner research is concerned with either identifying or evaluating the theories underlying and shaping our practice. It involves searching systematically and serendipitously for new perspectives and insights into practice. However, the development of understandings about the experience and process of research cannot be situated exclusively as self-expression or instruction. Rather the existing 'discipline' of research is made up of a vast and informative tapestry of categories, terms, processes, protocols and arguments that have been developed, tried and tested by colleagues and antecedents in many disciplines and fields of knowledge.

The ideas in this paper are concerned with developing a community of aware and informed practitioners who work within fields of artistic praxis. 'Praxis' in this sense is presented as a self-creative activity through which we make and shape ourselves as well as the wider community of our field. I argue that as practitioners we can become researchers of our own practice and that our visual, performance and textual outcomes importantly serve to demonstrate the kind of knowledge about the field generated by such practice. Whether these are ultimately presented as 'exegesis', 'thesis' or 'dissertation' is a moot point. More critical is how the ingredients and protocols described illuminate the praxis and illustrate a living form of theory.

The paper is necessarily brief and will consider three issues contained within the argument. Firstly notions of practitioner research as a living form of theory will be introduced. The central and guiding roles of praxis and reflexivity will be used to add to the debate and the paper will conclude with suggestions about ways existing research protocols and processes can be artistically woven into the process.


This brief paper has two purposes. The first is to suggest some reasons why the study of time is important and should be of interest to political analysts. The second is to present some data which link one aspect of temporal analysis, political impatience, with a range of political orientations and behaviors. Although the magnitude of the correlations reported is not large, the patterns of association suggest a syndrome to which more attention may be profitably turned.

Objective To study the CT manifestations of Graves ophthalmopathy(GO) and the correlation of CT features with clinical signs.Methods The diameters of medial rectus and lateral rectus were measured in 100 normal control individuals.In 100 patients with GO,the orbital structures(including extraocular muscles,apex of the muscle cone,globe displacement and so on) were studied,and the relationship between the CT appearances and clinical signs was evaluated.Results The normal values of medial and lateral rectus ranged from 2.9~4.9 mm and 2.2~4.7 mm,respectively.In fifty-five patients with GO,no abnormalities of orbital structure were found in 18% cases,only had ocular proptosis in 35% cases,all abnormal orbital changes were identified in 18%,and the remaining 29% only showed thickening of rectus.The different CT features in GO were accompanied with the special clinical signs accordingly.Conclusion In the patients with GO,the CT appearances are various and the different CT features have the special clinical signs accordingly.


for The 28th International Workshop on Water Waves and Floating Bodies, L'Isle sur la Sorgue, France, 7-10 April, 2013 1Hypersingular integral-equation solution for a finite-draft surface-piercing cylindrical shell at highand low-frequency Ronald W. Yeung* and Mohamed Hariri Nokob Department of Mechanical Engineering University of California at Berkeley Berkeley, CA 94720-1740, USA * Correspondence author: email@example.com † Presenter: firstname.lastname@example.com 1. Background A monocolumn structure, with a circular moonpool and internal dock to act as a so-called HUB, is considered as an intermediate station for transporting people to offshore locations in the Santos Oilfield in Brazil [1]. Such designs are promising and considered to be built. A split opening in the design allows marine vehicles in and out, thus acting as a floating harbor. In this work, we present a simplified model of such a harbor and develop the numerics to analyze the problem eventually. The body S considered is a floating bottomless harbor of circular cylindrical shape of radius and draft floating in deep water (see Fig.1). Modeling of similar problems using eigenfunction expansion method (EEM) gained interest in the 80's (see, e.g. Yeung [2]). We consider a general point P=(x,y,z) in the fluid domain and another point Q=(ξ η ζ) on the surface of S. The coordinate system is taken to be on the still free surface with the axis pointing upwards. We can state the "standard" problem as follows: ∇φ = 0 (1) φy −νφ = 0, y = 0 ; ∇φ = 0, y →−∞ (2) φn = V • n(P), V = (U1, 0,U2), for P on S (3) Here, the velocity potential isΦ = Re{φe} and (U1, U2) are the surge and sway velocities of S. The frequency factor ν =ω 2 /gis either zero or infinite in this work. The thickness of the boundary wall is infinitely thin and accordingly, special treatment is required as compared to bodies of finite thickness. The BIM is known to have difficulties dealing with this kind of problems. Hence we will use a special formulation for such thin-body geometry. The general integral equation over a three dimensional environment is given by:


The human face plays a prodigious role for automatic recognition of emotion in the field of identification of human emotion and the interaction between human and computer for some real application like driver state surveillance, personalized learning, health monitoring etc. Most reported facial emotion recognition systems, however, are not fully considered subject-independent dynamic features, so they are not robust enough for real life recognition tasks with subject (human face) variation, head movement and illumination change. In this article we have tried to design an automated framework for emotion detection using facial expression. For human-computer interaction facial expression makes a platform for non-verbal communication. The emotions are effectively changeable happenings that are evoked as a result of impelling force. So in real life application, detection of emotion is very challenging task. Facial expression recognition system requires to overcome the human face having multiple variability such as color, orientation, expression, posture and texture so on. In our framework we have taken frame from live streaming and processed it using Grabor feature extraction and neural network. To detect the emotion facial attributes extraction by principal component analysis is used and a clusterization of different facial expression with respective emotions. Finally to determine facial expressions separately, the processed feature vector is channeled through the already learned pattern classifiers.


MAKIN AND JONES DIAZ (2002) suggest that young children's early literacy is most strongly supported when early childhood educators, children's families and the wider community develop shared understandings about literacy —what counts, what is valued and validated, and whose voices are heard and whose voices are silent. Researchers such as Haas Dyson (1993), Kress (1997), and Stein (2003) argue that young children's literacy experiences comprise much more than developing the conventional processes of written language, but also include their use of a range of multiple semiotic symbol systems. This article will explore young children's constructions of literacy, and reveal the important role family members (e.g. parents, aunts, uncles, grandparents) and school staff (e.g. teachers, Elders, speech and language pathologists) play in mediating young children's literacy learning and development.


In order to reduce the production cost of sintering process,further optimization of current ore blending proportion was carried out based on the raw material condition and production situation of a 360 m2 sintering machine in Beiying Steel.Ensuring nearly invariable grade,basicity,SiO2 content and other parameters of all the blends,six ore blending schemes of low cost were designed with the proportion increase of low cost ore,the proportion decrease of high cost ore and the proportion adjustment of other materials.And sintering pot tests were conducted for verification.The results indicate that the total proportion of two kinds of Australian ore should not exceed 45% and the proportion of two kinds of Brazilian ore should be the same as much as possible.The optimizing ore blending scheme would bring a cost reduction of 16.02 yuan for per ton of sintering mixture and improvement of sintering indexes and sinter quality.The cost of sintering process could be further reduced,simultaneously an improvement of economic and technical indexes,only by proportion adjustment of present ore fines.


Nacrtak In forestry practice, during forest harvesting there are many different situations while skidding timber assortments, which are dealt with individually depending on the circumstances. The main purpose of this scientific paper is to offer a model for the calculation of the optimal distance for skidding timber assortments uphill or downhill, in mountain conditions. The working area i.e. the harvesting volume is situated between two storey (horizontal) forest roads. This solution would enable the forest experts to make the right decisions when planning timber assortment skidding, i.e. to achieve the most favorable financial results of the work. The method is based on work efficiency i.e. the time required for skidding certain timber assortments (logs and firewood), when skidding is done by animals, adapted tractor equipped with winch, and mobile cable crane.
