Cancer stem-like cells (CSCs) contribute to tumor recurrence and chemoresistance. Hence, strategies eradicating CSCs are crucial for effective anticancer therapies. Here, we demonstrate transcriptional upregulation of the heat shock proteins (Hsp90 and Hsp70) and their co-chaperones and enhanced activities of the Hsp system in both non-CSCs and CSCs in non-small cell lung cancer (NSCLC) cells. Genetic and pharmacologic strategies targeting Hsps eliminated both CSCs and non-CSCs of NSCLC, suggesting the functional role of the Hsp system in the two populations in NSCLC. We further identified Compound A, a natural product-derived compound, as a novel Hsp70 inhibitor eliminating both the CSC and non-CSC populations in NSCLC. Compound A inhibited the sphere-forming ability of NSCLC CSCs by inducing apoptosis. Compound A also suppressed the viability and colony-forming abilities of NSCLC cells (non-CSCs) and their sublines carrying acquired chemoresistance by inducing apoptosis with minimal toxicity in normal cells derived from various organs. Mechanistically, Compound A disrupted Hsp70 function by binding to the ATP-binding pockets of Hsp70. These data suggest the rationale to target the Hsp system for controlling both CSCs and non-CSCs in NSCLC and the potential of Compound A as a natural Hsp70 inhibitor to eliminate the two populations with limited toxicities.

Translocation programs have largely been focused on birds and mammals, however reptiles have been gaining public appeal thus allowing the creation of spaces for their conservation over the last few decades. With more than 80 % of turtle and tortoise species at risk of becoming extinct in the world, translocation may be the only option for recovering populations. In Mexico, 33 chelonian species, out of the 48 described, have a protection status but no translocation programs have been conducted. Therefore, we reviewed open literature on worldwide tortoise translocation projects to attempt the development of a guideline to improve success rate. We identified the main influencing factors for a successful outcome in a translocation: habitat suitability, acclimatization (soft release), selection of translocation candidates, monitoring post translocation and public acceptance of the translocation program. The information provided by this review will be useful to develop strategies for future tortoise translocations in Mexico and around the world.


Based on the theory of moelcular structure and the data derived from testing, the article analyzed the mechanism of the modified KHm, the drilling liquid agent, on the viscosity of the drilling liquid, namely, the polymerization(or multi -polymerization) of KHm and certain kinds of polymers produced the modified KHm, whose molecular structure and average distirdution of molecular weight are different so that viscosity of the drilling liquid can be improved.


Objective To analyse the characteristics of symptoms in patients with paroxysmal atrial fibrillation(PAF) and the effects of Betaloc on them.Methods One hundred patients with PAF confirmed by 24 h Holter monitoring were enrolled in our hospital.The ratio of the occurrence of asymptomatic AF was calculatd.All of those patients were treated with Betaloc for three months,their changes of AF were analyzed by Holter monitoring again.Multivariate logistic regression was applied for analyzing the correlation between symptoms and clinical features.Results Fifty-five patients(55%) were asymptomatic,and 45 patients were symptomatic.After treatment,clinical symptoms were absent in 28 patients,of whom 16 were sinus rhythm,12 were asymptomatic PAF.In the 55 cases of asymptomatic PAF,however,attacks of PAF were still present in 31 patients.The symptoms of AF were related with age and gender;The incidence of symptoms was higher in young female(P0.05).Symptoms were positively correlated with ventricular rate and AF-sinus(P0.01),but were negatively correlated with left atrial diameter(P0.01).Conclusion The incidence of asymptomatic PAF is in a high percentage.Betaloc could not only relieve the symptoms of AF patients,but also relieve the episodes of asymptomatic PAF.Young female patients,or patients with fast heart rate,or big difference of ventricular rate are subject to present symptoms,but the symptom is not found in patients with large left atrial diameters.


A low energy ion scattering technique for investigation of the first monolayer of a surface has been realized in an ion cyclotron resonance mass spectrometer. The secondary-ion mass spectrometry mode is also available in the same configuration. Preliminary results are shown for the analysis of the metal surface of a magneto-optical recording film.


Abstract End‐stage liver disease caused by the hepatitis C virus is a major indication for liver transplantation. However, recurrence of hepatitis in the graft is a major issue. HCV re‐infection after transplantation is almost constant, and recent data confirm that it significantly impairs patient and graft survival. Factors that may influence disease severity and consequent progression of HCV graft injury remain unclear. Chronic HCV infection develops in 60%–80% of patients, and 6%–28% ultimately progress to cirrhosis within 5 years. Pre‐transplantation antiviral treatment is not easily related to poor tolerance. Attempts to administer prophylactic post‐transplantation antiviral treatment are under evaluation but are limited by antiviral drug side effects. Treatment of established graft lesions with interferon or ribavirin as single agents has been disappointing. Combination therapy gave promising results, with sustained virological response in 25% of patients, but indications, modality and duration of treatment should be assessed.

High resolution digital elevation models (DEM) are becoming increasingly available for use as source data during the process of creating synthetic environments to support simulation systems. Several data sets that provide elevation points corresponding to 1 meter intervals on the earth surface are now available. However, multiple transformations must often be applied to the raw source data before it is suitable for use by any simulation system. These transformations have an impact on the fidelity of the final (simulation) synthetic environment that is difficult to quantify. Further, intuition alone now supports any claim that higher resolution source data necessarily results in generation of higher fidelity simulation data as a product of the transformation process. This paper documents an attempt to measure fidelity differences in final simulation synthetic environments that can be directly attributed to the resolution of the source data. Specifically, several lower resolution DEM are generated from a single high resolution (1 meter horizontal spacing) source DEM and all are used as source data for TIN construction. Automated planning software is applied to each and used as a metric to measure TIN quality.


We propose an authentication and key agreement protocol while preserving the anonymity of a mobile user in wireless mobile environments. When a mobile user and his visited network mu-tually authenticate each other, the anonymity of the user should be preserved. In order to provide user anonymity, we introduce new method of computing the temporary identity (TID) during the authentication process. TID is initially computed by a user at the beginning and updated by both user and network side during the execution of the protocol. In addition to guarantee-ing user anonymity, we also consider the secure key agreement at the same time.


Obesity, accompanied by insulin resistance, is a profound risk factor for Type 2 diabetes. Evidence is accumulating that lipids are implicated in the pathogenesis of Type 2 diabetes. We previously demonstrated that C75, a compound designed as a fatty acid synthase inhibitor, caused anorexia and significant weight loss accompanied by reduced fat mass. To investigate the role of fatty acid metabolism in obesity‐related diabetes, we utilized a DIO mouse model and a dose of C75 that reduced food intake until bodyweight was sustained during daily intraperitoneal administration. C75 exhibits multiple alterations in expression of hepatic genes to suppress fatty acid synthesis and to favor fatty acid oxidation. C75 reduces serum leptin level, implying the consequence of reduced body fat mass seen with C75 treatment in DIO mice. Compared to the hyperinsulinmic level of serum insulin in vehicle‐treated DIO mice, C75‐treated mice display the normal insulin level. C75 is involved in the regulation of hepatic glucose production by modulating CREB and AMPK phosphorylation. Our data also represent that C75 activates muscle AMPK, inactivating ACC, thus contributing to an increase in fatty acid oxidation. Our studies will provide a platform for the initial evaluation of our hypothesis that alteration of fatty acid metabolism is a novel strategy for improving the insulin impairment associated with obesity.


Background: Mental disorders of adulthood can be traced to childhood and adolescent disorders so attention to the mental health of young people is important. Objectives: We aimed to determine the mental health status of high-school students in Khorramabad and the factors that may affect it. Methods: This cross-sectional study included 1 202 high-school students in Khorramabad in the 2015–2016 academic year. Students were selected using stratified and multistage cluster random sampling. Data were collected on sociodemographic characteristics of the students, and the General Health Questionnaire (GHQ-28) was used to assess symptoms of mental disorders. Logistic regression analysis was used to evaluate the relationship between the


Owing to their single atom-layer structure, actual bending stiffness of single-walled carbon nanotubes is much lower than that given by the elastic shell model if the commonly defined representative thickness is used. In this paper, it is proposed that the effective bending stiffness of single-walled nanotubes should be regarded as an independent material parameter not related to the representative thickness by the classic bending stiffness formula. Based on this concept, the modified formulas for the critical axial strain and the wavelength of axially compressed buckling are found to agree well with known data of molecular-dynamic simulations. On the other hand, in contrast to single-walled nanotubes, bending stiffness of multiwalled nanotubes is found to be well estimated by the classic bending stiffness formula when adjacent nanotubes are squeezed severely so that the induced high friction barrier prevents interlayer slips. In particular, these results offer a plausible interpretation for the wavelength of large-strain local buckling of multiwalled carbon nanotubes under bending observed by Falvo et al. @Nature~London! 389, 582 ~1997!#.

The present investigation entitled effect of integrated nutrient management on growth and yield of bitter gourd (Momordica charantia L.) was carried out during Kharif 2018 at College farm, College of Horticulture, S. D. Agricultural University, Jagudan, Dist. Mehsana, Gujarat. The experiment was laid out in Randomized Block Design with three replications with fourteen treatments under study. Treatments were evaluated with respect to growth and quality parameters of bitter gourd. Treatment 75% RDN through vermicompost + 25% N through urea + Azotobacter @ 2.5 lit/ha + PSB @ 2.5 lit/ha (T11) was found significantly higher as compare other treatments. The growth parameters viz., maximum vine length (186.70 cm) at 45 DAS and (511.33 cm) at 90 DAS and number of branches per plant (12.87) at 90 DAS were recorded with treatment given by 75% RDN through vermicompost + 25% N through urea + Azotobacter @ 2.5 lit/ha + PSB @ 2.5 lit/ha (T11).


The invention relates to a turbine with blades that allow a bending elastic mediated buckling change. Characteristic is a passive adjustment of the operating point of the turbine by the fluid dynamic moment by means of a combined pitch, camber and Schrankungsanpassung. The passive characteristic is achieved in a constructive way by a two-point bearing of the blades (3, 4) on the turbine shaft (1) and along a travel freely movable blade bearing ring (2). The force results from the dynamic balance between centrifugal force, spring moment, torque and fluid dynamic moment. One of the bearings (3a, 4a) forms the spring base point and the other the pivot point of the adjustment process. The invention can be carried out as a horizontal and as a vertical axis turbine for all conventional fluids as well as for a repeller and a propeller operation and achieved over unregulated or only pitch-controlled embodiments, a significant performance improvement. Start behavior, power dynamics and average power are also improved. Particularly preferred embodiments of the passive control for the Wells turbine, each for use in OWC ocean wave and in tidal current power plants and for the Darrieus turbine for wind energy. There is further potential in the area of variable-speed fans as well as in variable drive systems with special optimization requirements.


Abstract Meistera caudata is a new endemic Vietnamese species that belong to the Zingiberaceae family. In the present work, the chemical compositions of essential oils (EOs) from M. caudata leaves and rhizomes and their antimicrobial activities were reported for the first time. The gas chromatography-mass spectrometry (GC/MS) analytical results revealed that α-pinene, β-pinene, and camphene were the most abundant components in both EO samples. Specifically, the leaves EO contained 27.61% of α-pinene, 21.29% of β-pinene, and 8.62% of camphene while the figures for the rhizomes EO were 10.37%, 9.69%, and 12.1%, respectively. The EOs were also shown to exhibit strong antimicrobial activities against several pathogenic bacterial and fungal strains with MIC values ranging from 8-128 μg/mL, with the most potent activity against Enterococcus faecalis (8 μg/mL). GRAPHICAL ABSTRACT


A phytochemical investigation of an aqueous ethyl alcohol (EtOH) extract of the flowers of Nicotiana tabacum L. led to the identification of one new eudesmane-type sesquiterpenoid (1) and 14 known compounds, including 7 flavones (2-8), 6 phenolic acids (9-14), and 1 coumarin (15). The chemical structure of 1 was established on the basis of high-resolution electrospray ionization (HRESIMS) and 1D and 2D NMR analyses, while the other structures were elucidated by 1D NMR and LC–MS data. The antiphytopathogenic activities of all the isolated compounds were tested to determine their antifungal activity against Valsa mali var. mali, Alternaria porri, and Botrytis cinerea at a concentration of 10 µg/mL. Compound 4 exhibited more potent antifungal effects against Valsa mali var. mali with a % growth inhibition of 47.9 ± 1.2%, while the others only showed insignificant activities.


An analytical first order solution to the one-dimensional advection-dispersion equation with spatially variable retardation factor is derived using a generalized integral transform method to investigate the transport of sorbing but otherwise non-reacting solutes in hydraulic homogenous but geochemically heterogeneous porous formations. The solution is derived under conditions of steady-state flow and arbitrary initial and inlet boundary conditions. The results obtained by this solution agree well with the results obtained by numerically inverting Laplace transform-generated solutions previously published in the literature. The solution is developed for a third or flux type inlet boundary condition, which is applicable when considering resident solute concentrations and a semi-infinite porous medium. For mathematical simplicity it is hypothesized that the sorption processes are based on linear equilibrium isotherms and that the local chemical equilibrium assumption is valid. The result from several simulations, compared with predictions based on the classical advection-dispersion equation with constant coefficients, indicate that at early times, spatially variable retardation affects the transport behavior of sorbing solutes. The zeroth moments corresponding to constant and variable retardation are not necessarily equal. The center of mass appears to move more slowly, and solute spreading is enhanced in the variable retardation case. At late time, when the travel distance is much larger than the correlation scale of the retardation factor, the zeroth moment for the variable retardation case is identical to the case of invariant retardation. The analytical solution presented in this paper provides more flexibility with regard to the inlet conditions.

Stability of infrastructure during earthquakes demands ground response analysis to be carried out for a particular region as the ground surface may suffer from amplified Peak Ground Acceleration (PGA) as compared to bedrock PGA causing instability. Many studies have been carried out the world over using different techniques but very few studies have been carried out for the northern part of India, Punjab situated at latitude of 31.326° N and longitude of 75.576° E, which is highly seismic and lies in seismic zone IV as per IS:1893-2016. In this paper 1-D equivalent non-linear ground response analysis has been conducted for sixteen sites of Jalandhar region, Punjab (India) by using five earthquake motions. Input ground motions are selected from the worldwide-recorded database based on the seismicity of the region. Based on the average SPT-N values, all the sites have been classified as per the guidelines of National Earthquake Hazard Reduction program (NEHRP). Shear modulus (G) was calculated using correlation between G and SPT–N Value. The ground surface PGA varies from 0.128 to 0.292 g for the sites of Jalandhar region with Amplification Factor values varying from 1.08 to 2.01. Hence the present study will be useful to the structural designers as an input towards suitable earthquake resistant design of structures for similar sites.

With the circuit complexity increasing.More and more system designers begin to use IP to accelerate the design process.So some techniques are needed to protect the IP from being copied or tampered or stolen.An IP protection method combining EDA software and FPGA chips is purposed in this paper,which can prevent effectively the IP from being stolen as well as the ultimate implement from being illegally copied.


A D-shaped plastic optical fiber (POF) assisted by a long period grating (LPG) is proposed as a refractive index (RI) sensor. The LPG is fabricated on the D-shaped region by a simple mechanical die press print method. The RI sensing performances of the D-shaped POFs with LPGs imprinted on POFs with different diameters (of 0.25, 0.50, and 1.00mm) are studied, and the results show that the D-shaped POF with an LPG achieve higher RI sensitivity than that of the one without an LPG. When the D-shaped POF with an LPG fabricated on POF with a thin diameter of 0.25mm, the extremely high sensitivities of 2676%/RIU and 9786%/RIU are obtained in the RI ranges of 1.33-1.40 and 1.40-1.45, respectively. Additionally, the temperature dependence of the sensor is also investigated. The experimentally confirmed high sensitivity of our proposed sensor, combined with its simple structure, easy fabrication and low cost, makes it a promising candidate for RI sensing applications.

Several petrographic types of inclusions [objects which show no textural evidence of having crystallized from a melt, as opposed to chondrules] are present in C3 carbonaceous chondrites. Ca,Al-rich inclusions (CAI) occur in both fineand coarse-grained varieties, and consist primarily of melilite, spinel, perovskite, and clinopyroxene (Fig. 1). Amoeboid olivine inclusions are composed of fine-grained forsterite aggregates, sometimes containing refractory material (Fig. 1). Mineralogical and textural features have been cited to support the hypothesis that these inclusions represent high-temperature nebula condensates (1,2,3). Further support for the primitive nature of these inclusions accrues from their hi h concentrations of refractory trace elements ( 4 ) , very primitive initial 8$Sr/86Sr ( 5 ) , and oxygen isotopic anomalies (6).


Background: Many different techniques have been attempted for cleft repair. The most significant of these is Millard's "rotational advancement" technique devised in 1958. However, some of the few disadvantages of this technique are the nostril size discrepancy and a prominent scar on the cleft side. We describe a slight variation of this technique for treatment of several cases of unilateral cleft lip. Methods: The preoperative design of the surgical method was drawn on the skin, the vermilion, and the oral mucosa. After completion of the preoperative marking, the wide dissection was performed to separate the orbicularis oris muscle completely from the abnormally inserted bony structure and the enveloped skin-mucosal flap. The freed orbicularis oris muscle was then reconstructed with full width. On the cleft side alar crease incision is avoided and the incision is taken on the nasal mucosa only to construct nasal floor and avoid scar Results: Unilateral cleft lip repair using this technique was conducted in 42 patients between 2015 and 2017. A total of 05 patients (12%) required a secondary operation on the lip after the first unilateral cheiloplasty. In all patients, satisfactory surgical outcomes were obtained with an indistinct scar and a well-aligned lip contour. Conclusions: the slight variation on the cleft side by avoiding skin incision is a good technique to acquire a natural and balanced shape in unilateral cleft lip repair.


This paper concerns the design method and implementation of main modules, dedicated to miniaturized digital ultrasonic devices, using advanced System-on-Chip technique. It is intended to diagnostic imaging applications such as echography. The proposed implementation allows the integration of all acquisition front end as well as signal and video processing on only one single chip. It will make possible to visualize the ultrasound images in real time. It requires high resolution and real-time image processing. The proposed design, which integrates the B-mode processing modules, includes digital beamforming, quadrature demodulation of RF signals, digital filtering, envelope detection, and video processing of the received signals. This system handles 128 scan lines and 6400 samples per scan line with a 90° angle of view span. The design uses a minimum size look-up memory to store the initial scan information. Rapid prototyping based on ARM/FPGA platform combination is used to validate the operation of the described system. This system offers significant advantages of portability and a rapid time to market.

In this paper we describe ACHILLES, a system for ondemand delivery of software from stationary servers to mobile clients over wireless network links. ACHILLES supports disconnected operations and employs mechanisms for hiding latency of slow networks. It's main features are a cache replacement policy that uses a simple cost model to determine which software components should be removed from the cache, and a mechanism called resource qualification for checking if resources of a mobile computer are sufficient for the successful execution of applications that are to be loaded. An initial implementation has been evaluated and results showing trade-offs for cache replacement policies are presented.

This paper presents unified force and position control based on sliding mode control (SMC) for a series elastic actuator (SEA). Compliant motion of robotic systems is crucial when dealing with unstructured environments as in the case of physical human-robot interaction. Therefore, not only traditional mechanical systems with stiff joints but also mechanically compliant systems such as SEAs have been actively studied. In order to accomplish versatile tasks, the strategy enabling both position control and force control is favorable. In this paper, the controller synthesizing position and force controllers on the basis of SMC for the control problem of SEAs is proposed by extending our previous work. Simulation results demonstrate the feasibility of the proposed method.


The Congenital Anomaly Appraisal, a tool used to screen for hidden congenital anomalies, has been in existence since 1960 but is not yet widely used. Consequently, many infants with hidden congenital anomalies are not diagnosed until their condition becomes serious. The purpose of this article is to describe the six basic steps of the appraisal and explain why each step is done. It is hoped that, as more nurses become aware of this simple and inexpensive appraisal, they will urge their hospitals to make it a routine procedure with every newborn immediately after birth.


In South Africa, as in every other country, interest in modern advances in statistical theory and technology grew rapidly after World War II. The earliest attempt to found a Statistical Association was made by Professor B. de Loor, Dr. (then Mr.) H.S. Sichel and myself in October, 1950. The records show that we consulted about twenty people in various parts of the country and decided that the time was not quite ripe.


Let R be an algebra over a field k, and P, Q be two nonzero finitely generated projective R-modules. By adjoining further generators and relations to R, one can obtain an extension S of R having a universal isomorphism of modules, i: P(R S -Q (R S. We here study this and several similar constuctions, including (given a single finitely generated projective R-module P) the extension S of R having a universal idempotent module-endomorphism e: P 0 S P 0 S, and (given a positive integer n) the k-algebra S with a universal k-algebra homomorphism of R into its n X n matrix ring, f: R mn(S). A trick involving matrix rings allows us to reduce the study of each of these constructions to that of a coproduct of rings over a semisimple ring Ro (= k X k X k, k X k, and k respectively in the above cases), and hence to apply the theory of such coproducts. As in that theory, we find that the homological properties of the construction are extremely good: The global dimension of S is the same as that of R unless this is 0, in which case it can increase to 1, and the semigroup of isomorphism classes of finitely generated projective modules is changed only in the obvious fashion; e.g., in the first case mentioned, by the adjunction of the relation [PI = [QJ. These results allow one to construct a large number of unusual examples. We discuss the problem of obtaining similar results for some related constructions: the adjunction to R of a universal inverse to a given homomorphism of finitely generated projective modules, f: P Q, and the formation of the factor-ring R/Tp by the trace ideal of a given finitely generated projective R-module P (in other words, setting P = 0). The idea for a category-theoretic generalization of the ideas of the paper


We define a non-parametric form of threshold decision and show that the new form naturally leads to a covering theorem and its converse. This covering theorem gives us a key to find interrelationships between several erasure criteria.


The purpose of this research is to investigate the effect of transformational and transactional leadership styles on firms' financial performance in a context of knowledge-intensive firms and the mediating role of exploitative and exploratory innovations in this relationship. To achieve this purpose, a quantitative research was conducted on 201 top executives working in knowledge-intensive firms in the context of an emerging country, namely Tunisia. The data analysis was performed via the structural equation modelling method. As a result, the empirical study revealed that the transformational leadership style is a key determinant of exploitative and exploratory innovations and firms' financial performance. In this perspective, the two types of innovation partially mediate the link between transformational leadership and financial performance. However, transactional leadership affects only exploitative innovation. This original study offers a better understanding of the contribution of the transformational and transactional leadership styles on exploitative and exploratory innovations and the firms' financial performance in a context of firms' intensive knowledge. It offers a reading grid for managers of knowledge-intensive firms to better lead and identify key elements that may boost the firms' innovation ambidexterity and performance.

The expansion of actors and instruments in sovereign debt markets through bond financing generated a coordination problem among bondholders during the debt restructuring process. There is a risk that an individual bondholder will be passive or act against the restructuring slowing down or even precluding the process of restructuring even though it is in the general interest of bondholders as a group, not to mention the population of the country experiencing the shortage of funds for public welfare. In particular, the disruptions to sovereign debt restructuring by frivolous litigation is considered as one of the main threats. This dissertation is the first major study devoted to sovereign bonds structured through a trust arrangement and the promising features that such a legal structure possesses for an effective and efficient sovereign debt restructuring. It provides a comprehensive inquiry into the evolution of the mechanisms to coordinate creditors, with a focus on bondholders and institutional frameworks which facilitated this coordination. It examines intriguing primary sources from League of Nations archives and provides in-depth case studies on the functionality of the trustees in sovereign bond restructurings performed by Argentina in 2016 and Ecuador in 2008. Assessing the utility of trust arrangements to address coordination problems, this thesis is driven by the puzzle: How to better balance (i) the need for smooth sovereign debt restructurings, which by definition entails some losses for creditors, with (ii) bondholders' legitimate interests? What approach can be used in constructing a legal and institutional framework for trustees to promote the best interest of the bondholders in sovereign debt restructuring? As a solution, it seems that incentives for bond trustees to pursue debt sustainability will achieve both goals. In this regard, recognition of the concept of debt sustainability, being in substance the IMF and WB debt sustainability assessment, as the best interest of bondholders in sovereign debt restructuring is beneficial from multiple aspects. It enables a bond trustee to excel in its role as a guardian of bondholders by following the best interest of bondholders in exercising its discretion. Moreover, it fosters an equilibrium between the interests of private creditors and a state taking into account its socio-political aspects.


The human oral cavity is a complex ecosystem harboring hundreds species of microbes that are largely living on the tooth surfaces as dental biofilms. Most microbes in dental biofilms promote oral health by stimulating the immune system or by preventing invasion of pathogens. Species diversity, high cell density and close proximity of cells are typical of life in dental biofilms, where microbes interact with each other and develop complex interactions that can be either competitive or cooperative. Competition between species is a well-recognized ecological force to drive microbial metabolism, species diversity and evolution. However, it was not until recently that microbial cooperative activities are also recognized to play important roles in microbial physiology and ecology. Importantly, these interactions profoundly affect the overall biomass, function, diversity and the pathogenesis in dental biofilms. It is now recognized that every human body contains a personalized oral microbiome that is essential to maintaining the oral health. Remarkably, the indigenous species in dental biofilms often maintain a relatively stable and harmless relationship with the host, despite regular exposure to environmental perturbations and the host defense factors. Such stability or homeostasis results from a dynamic balance of microbial-microbial and microbial-host interactions. Under certain circumstances, however, the homeostasis may breakdown, predisposing a site to diseases. In this review, we describe several examples of microbial interactions and their impacts on the homeostasis and pathogenesis of dental biofilms. We hope to encourage research on microbial interactions in the regulation of the homeostasis in biofilms.


Non-motorized transport modes,which normally include cycling and walking,are considered to be ecological and sustainable for the advantages of environmental friendly,healthy,good for releasing traffic congestion and cheap.The governments in the Netherlands have proposed a series of effective policies to promote the development of non-motorized transport modes in the whole country and have wined an international reputation for their advanced and successful non-motorized transport infrastructure.It is concluded that non-motorized transport modes could not replace all kinds of transport modes because they could only play an important role in short-distance journey.It is extremely important to integrate non-motorized transport modes with other modes especially public transport to establish an appropriate practice strategy and finally develop a sustainable transport system.


To study the laws of the crater formed by explosion and stress wave propagation at different burial depths in soils,the effects on the crater produced through explosion were studied through free-field experiments and numerical simulation,demonstrating the macroscopic characteristics of explosion.The radius of the crater and the recorded waveforms of pressure were acquired in the site of soil.The empirical formulas of the crater formed by explosion and propagation laws of shock wave in soils were concluded.The laws of stress wave propagation at different burial depths in soil were obtained,the semi-rational formulas of crater formed by explosion were inferred,and the empirical formulas of the crater were obtained at the phase of the semi-closed explosion.

Now-a-days voice assistants are making people's day-to-day routine simpler and it saves time as well. But, even after voice assistants are easy to operate, there are many people who cannot use voice assistant even if they wanted to. The main reason behind this issue is language barrier. People living in urban India are using voice assistants on daily basis. But, people living in rural areas are not fluent in English even to start a conversation with any voice assistant. Hence, paper proposes of the unique system based on the initiative to improve connectivity between the people living in rural India and the world. The core idea behind this initiative is to create an intelligent voice assistant system that can interact with people in their local language so that the system can help them to make their day to day life simpler. The system is designed while taking the rural life in consideration as well as their basic needs. This paper also tends to explore some new possibilities.


Based on the characteristics of network culture and its effects on college students,this paper anaˉlyzes the opportunities and challenges faced with the ideological and political education of college students unˉder network conditions,and puts forward some thoughts and suggestions as to how to carry out ideological and political education of college students in CIT with network conditions.


In the network era, contemporary college students have more convenient accesses to information. With the rapid
development of internet technology, students have a broader latitude to develop. However, the diversity of information resources
in the network environment may also have a negative impact on their mental health and even affect their normal learning and
educational activities. Therefore, in view of the factors influencing college students' mental health under the network environment,
this thesis puts forward some measures to construct a new mode of college students' mental health education.


The prescription of Methotrexate is well-recognized for various neoplastic diseases. For Rheumatoid arthritis, it is prescribed once a week, low-dose regimen for the treatment of psoriasis and rheumatoid arthritis. Apart from providing therapeutic benefit, it is not devoid of side effects like oral ulceration which may be due to over dosage regarding its once-weekly regime. This case report describes a patient with inherent Methotrexate toxicity that developed oral mucositis due to Methotrexate being given for rheumatoid arthritis.


Micro-features such as grooves and lenses, which perform optical functions in flat displays, should be manufactured with a good form accuracy because this is directly related to their optical performance. As the size of the display increases, it is very difficult to maintain a high relative accuracy because of the inherent geometric errors such as the waviness of a large-area plate. In this paper, the optical effect of these geometric errors is investigated, and surface-referenced micro-grooving to measure and compensate for such geometric errors on line is proposed to improve the form accuracy of the micro-grooves. A PZT-based fast depth adjustment servo system is implemented in the tool holder to maintain a uniform groove depth in reference to the wavy surface. Through experiments, the proposed method is shown to be an efficient way to produce high-quality micro- grooves on a wavy die surface.

Amelogenesis imperfecta is a group of hereditary defects of enamel, unassociated with any other generalized defects. It is classified into 14 subtypes according to different clinical and genetic features. According to its clinical features, it is classified into hypoplastic type, hypocalcified type and hypomaturation type. However, these features tend to co-exist often. Dental features associated with amelogenesis imperfecta include quantitative and qualitative enamel deficiencies, pulpal calcification, root malformations, abnormal eruption, impaction of permanent teeth, progressive resorption of root and crown, congenital missing teeth and anterior and posterior open bite occlusions. The first case patient is a 16 month-old child with discoloration of deciduous teeth. All of her deciduous and permanent dentition has shown amelogenesis imperfecta. The restorational, orthodontic and recent prosthodontic treatments have been completed. Another patient is a 9 year and 3 month-old child with amelogenesis imperfecta in both deciduous and permanent dentition. The restoration has been done and the prosthodontic treatment is planned after the completion of growth. Above cases indicate that amelogenesis imperfecta occurs both in deciduous and permanent dentition, and it requires the long term treatment and care.


Although in recent years the interest for daylighting in buildings has experienced a notable growth in developed countries, the same is not true in some emerging countries. There is a lack of studies and recommendations for some typology of buildings, such as industrial buildings in Brazil, especially regarded to the employee's health. Even these buildings having windows and other daylighting devices, its daylighting is poor due to undersizing or even lack of maintenance. Thus, the most common way to obtaining an adequate amount of lighting in such buildings is through artificial lighting systems with uniform general illumination, despite the great availability of daylight. The demand for lighting is still influenced by the amount to be provided for spaces and specifics tasks according consecrated standards that do not consider light quality and visual claims of the employees. However, light quality is extremely important because it is closely related to productivity, health and security of employees. This paper discusses the inclusion of daylighting in industrial design process as well in standards concerning that building typology that consider the wellbeing and health of the employees.


New classical modalities of atomic force microscopy continue to emerge to achieve higher spatial, spectral, and temporal resolution for nanometrology of materials. Here, we introduce the concept of a quantum mechanical modality that capitalizes on squeezed states of probe displacement. We show that such squeezing is enabled nanomechanically when the probe enters the van der Waals regime of interaction with a sample. The effect is studied in the non-contact mode, where we consider the parameter domains characterizing the attractive regime of the probe-sample interaction force.


The scattering of phonons from a substitutional impurity in a simple cubic lattice is studied in detail. The scattering amplitude is expressed in terms of partial waves characterized by the irreducible representations of the point group of the lattice, and the total scattering cross section is found by using the optical theorem. The condition for occurrence of resonances in each partial wave amplitude is investigated. In an appendix, a table of the Green's function integrals for a simple cubic lattice is given.


Dynamic simulation of power system transient stability is important for planning, monitoring, operation, and control of electric power systems. However, modeling the system dynamics and network involves the computationally intensive time-domain solution of numerous differential and algebraic equations. This results in a transient stability simulation implementation that does not satisfy the real-time constraints of online dynamic security assessment. This paper presents a parallel implementation of the dynamic simulation on a high-performance computing platform using parallel simulation algorithms and architectures. It enables the simulation to run even faster than real time, enabling the "look-ahead" capability to study pending stability problems in the power grid.


The C18H24 diamondoid hydrocarbon triamantane reacts with bromine largely at the 2-position and with lead tetrabenzoate largely at the 3-position; 2-bromotriamantane can be isomerised to 9-bromotriamantane and the 9-methyl derivative can be obtained directly from a C19H26 precursor by aluminium chloride-catalysed rearrangement.


Mass spectrometric sampling of quasimolecular ions with charge as high as 4+ has been achieved by Electrohydrodynamic Ionization Mass Spectrometry (EHMS). Triply and quadruply charged sodium ion adducts of poly(ethylene glycol) 4000 oligomers with mass exceeding 3500 u were sampled from glycerol solution without fragmentation. Although the mass of these ions exceeded the nomical mass range of the spectrometer, they were detected because of multiple charge which lowered their mass-to-charge ratio. From the mass spectral intensities of these oligomer ions, the number average molecular weight of the polymer was caculated, and found to be in good agreement with results of an ASTM standard method.


Insects are the most abundant and diverse animal class on Earth, and they are associated with an amazing variety of symbiotic microorganisms, which participate in many relationships with the hosts (Douglas, 2015). For example, the fungal symbiont (Leucoagaricus gongylophorus) of leaf-cutting ants produces diverse enzymes for the degradation of plant material (Kooij et al., 2016). Similarly, Bacillus pumilus isolated from the gut of wood boring Mesomorphus sp. (Coleoptera: Tenebrionidae) exhibits significant cellulolytic and xylose isomerase activities (Balsingh et al., 2016).

The Lepidoptera, including moths and butterflies, is one of the most widespread and widely recognizable insect orders in the world. Although butterflies and moths play an important role in the natural ecosystem as pollinators and as food in the food chain, their leaf-chewing larvae are often problematic in agriculture, as their main source of food is live plants (Mithofer and Boland, 2012). The leafworm Spodoptera littoralis (Lepidoptera: Noctuidae) is a highly polyphagous lepidopteran pest found worldwide and also an important model system used in a variety of biological research. Recent extensive surveys of its microbiome reveal that Enterococcus mundtii is one of the predominant gut microorganisms of S. littoralis and present at high frequency (Tang et al., 2012; Chen et al., 2016; Teh et al., 2016). Particularly, a stable isotope labeling-based approach suggested that this phylotype was also highly metabolically active inside the host across life history of S. littoralis, indicating the significant role played by E. mundtii in host biology (Shao et al., 2014). Therefore, the symbiotic E. mundtii probably constitutes a key factor for the success of this generalist herbivore in adapting to different environments and food sources. The aim of this study was to produce a genome sequence of the strain SL 16, which would assist in understanding of the coevolution of the microbe and the insect host. The dataset has been submitted to NCBI Whole Genome Shotgun (WGS) projects and is reported here, providing an overview of the genome sequence and relevant features of gut symbiotic E. mundtii.

"People's theatre" as a kind of programme to unite the nation, and various attempts to realise the programme, in the 18 th-20 th centuries' France, are considered. "People's theatre" manifestations are being analysed in the context of society's state. It is shown that a truly successful "People's theatre" is not confined by only-national repertory, neither does it express any official ideology; but does contribute to the development of a uniting culture space.


This paper studied on the legislation process for national mobilization of the company and laborers, especially focused on Munitions Companies Act(Gunjukaishaho), and its legal operations both in japan and Korea, which led to intensive mobilization of colonial Koreans. The results of studies are as follows.
1. Legislative process - The concept of national mobilization originated from the Munitions Industry Mobilization Law in 1918, which was made after the model of German wartime mobilization system, and was actualized by legislation of National Mobilization Law in 1938 just after the Sino-Japanese War, finally reinforced by the legislation of the Munitions Companies Act in October of 1943, which was made for the reverse the tide in the Pacific war by producing munitions including air fighters in a high speed, which led to more intensive mobilization of women and adolescents as well as japanese men.
2. Logistics mobilization in colonial Korea - The Japanese Government General in korea initiated a logistic mobilization policy in October of 1944, which was similar to Munitions Companies Act in Japan, which was the result of the enormous pressure from the japanese government, munitions corporate group(Zaibatsu), and military powers. This was the very crucial trigger to intensify the nation-wide forced mobilization(Choyo)
3. Influence on korean mobilization - After the introduction of Munitions Companies Act in korea, koreans mobilized into munitions company in north area of korean peninsula and japanese islands increased in a high speed, which brought about under population in south korea. Nevertheless, The Japanese Government General in korea mobilized more koreans including women and adolescents in the name of Jyosei Kinro Teishintai or Kinrohokokutai to fill up the labor shortage in japan. The mobilized koreans were put mainly into japanese munitions companies, which were granted a number of favors for their pains and cooperations. That is the reason why the japanese munitions companies as well as japanese government won't be free from the responsibility and compensation for mobilized koreans.


The purpose of this paper is to compare thermophysical properties of refrigerant-lubricant mixtures containing traditional POE lubricants to those containing advance (or optimized) POEs. The general methods for data acquisition and processing, along with creation of Daniel charts were in accord with those developed by Seeton (2009). The results of measurements involving mixtures of traditional POEs with R-32 or R-410A show that lubricant viscosities in the compressor at various conditions within the normal operating envelope decrease by as much as 25-54%. This illustrates the excessive lubricant viscosity dilution of R-32 relative to R-410A with traditional POEs used today with HFCs refrigerants. The solution property measurement technique was also used to develop a class of advanced ester POE lubricants optimized for R-32 to eliminate the viscosity dilution problem. Significant energy savings can be achieved through proper optimization of lubricant/refrigerant solution properties to provide the best balance of lubrication in the compressor while maintaining excellent heat transfer in the refrigeration cycle. Miscibility between new low Global Warming Potential (GWP) refrigerants and POE lubricants is a property that has to be considered, since a miscibility gap at concentrations between 10% to 20% (or higher to 30%) in volume may become an issue in oil return in refrigeration systems and its performance evaluated as Coefficient of Performance (COP). The advanced ester POE lubricants show improvement in the miscibility and viscosity issues. The miscibility gap was eliminated such that the new products are fully miscible from -20°C to 40°C. Viscosity dilution was limited to closely match the typical viscosity dilution shown in the baseline pair of R410A and an ISO 32 traditional POE. Finally, a comparison of concentrations and solution viscosities of traditional and advanced ester POE lubricants with R410A and R32 refrigerants, using actual conditions measured in a three ton air conditioning system, show a solution viscosity improvement when as ISO grade increases, with lower concentrations of refrigerant in oil than in the baseline of R410A and an ISO 32 traditional POE.


Consider a set P of n points in R. In the discrete median line segment problem, the objective is to find a line segment bounded by a pair of points in P such that the sum of the Euclidean distances from P to the line segment is minimized. In the continuous median line segment problem, a real number l > 0 is given, and the goal is to locate a line segment of length l in R such that the sum of the Euclidean distances between P and the line segment is minimized. To begin with, we show how to compute (1 + ε∆)and (1 + ε)-approximations to a discrete median line segment in time O(nε−2d log n) and O(n2ε−d), respectively, where ∆ is the spread of line segments spanned by pairs of points. While developing our algorithms, by using the principle of pair decomposition, we derive new data structures that allow us to quickly approximate the sum of the distances from a set of points to a given line segment or point. To our knowledge, our utilization of pair decompositions for solving minsum facility location problems is the first of its kind – it is versatile and easily implementable. Furthermore, we prove that it is impossible to construct a continuous median line segment for n ≥ 3 non-collinear points in the plane by using only ruler and compass. In view of this, we present an O(ndε−d)-time algorithm for approximating a continuous median line segment in R within a factor of 1 + ε. The algorithm is based upon generalizing the point-segment pair decomposition from the discrete to the continuous domain. Last but not least, we give an (1 + ε)-approximation algorithm for solving the constrained median line segment problem in R2 where an endpoint or the slope of the median line segment is given at input. These algorithms are space-subdivision and prune-and-search approaches, and their time complexities are sub-quadratic in n. 2012 ACM Subject Classification Theory of computation → Computational geometry; Theory of computation → Facility location and clustering


We propose a framework that provides a programming interface to perform complex dynamic system-level analyses of deployed production systems. By leveraging hardware support for virtualization available nowadays on all commodity machines, our framework is completely transparent to the system under analysis and it guarantees isolation of the analysis tools running on top of it. Thus, the internals of the kernel of the running system needs not to be modified and the whole platform runs unaware of the framework. Moreover, errors in the analysis tools do not affect the running system and the framework. This is accomplished by installing a minimalistic virtual machine monitor and migrating the system, as it runs, into a virtual machine. In order to demonstrate the potentials of our framework we developed an interactive kernel debugger, named HyperDbg. HyperDbg can be used to debug any critical kernel component, and even to single step the execution of exception and interrupt handlers.

S-LSR is a compact ion cooler ring built in ICR, Kyoto University, aiming at creating ultra-low temperature ion beam by laser cooling. In order to approach lowest possible temperature at S-LSR in an experiment, parameters of laser cooling should be carefully chosen by simulation. This paper mainly concerns optimization of laser cooling parameters and prediction of possible low limit of beam temperature at S-LSR. Firstly, the adiabatic capture process of ion beam is introduced and studied. Then, different laser profile parameters are compared and an optimized value is chosen. After that, optimized solenoid field strength for 3-D coupling is proposed. At last, by choosing the parameters proposed, the lowest beam temperature achievable for S-LSR is predicted to be 10 K in transverse direction and 0.05 K in longitudinal direction.


The Final Agreement peace process called Peace stable and durable, was established in Havana Cuba with delegates of the National Government and representatives of the Revolutionary Armed Forces of Colombia-army of the FARC-EP Pueblo, with the support of international organizations and facilitating countries where the commitments and obligations of both parties was established, setting six points which are identified and the main needs, problems, project development, implementation of a work plan together and verification of compliance.

 This agreement an objective analysis, in order to get a point of view of the document itself and the commitments of the parties acquired in this is done; because from October 2, 2016 to be legalized, through the plebiscite, all of Colombian society can make the judgment of what there recorded. The impacts will be in the three aspects of the country, as it is economically, socially and politically.


When commencing a study of British jade axes some years ago I became interested in a macehead from Dorchester, Oxfordshire, which had been identified as a diopside-schist. This had been presented to the Ashmolean Museum in 1921 by the late Mr Strickland Gibson. Mr H. J. Case of the Department of Antiquities at the Ashmolean Museum kindly arranged for me to examine this mace-head and I am indebted to him also for all details of its history and its dimensions. The mace-head (reg. No. 1921, 1) is broken across transversely at the shaft-hole. The unbroken end is convex, smoothly rounded and its end is 4-5 centimetres from the centre of the shaft-hole which itself is 2 centimetres in diameter. The cross-section is that of a slightly flattened cylinder varying from 4-3 to 4-4 centimetres in diameter. The material is a rather light coloured banded compact schist and the bands, some dark, others lighter in colour, are sharply folded (pi. LXVIa). Examination of the thin section of this mace-head shows that the rock is a hornblende-schist with some bands rich in epidote and some in pyroxene. The darker bands consist mainly of hornblende, with occasional sphene and rare grains of feldspar. Buff-coloured bands consist of pyroxene (pale bluish green) with turbid grains of altered colourless feldspar (probably andesine) and greenish bands consist mainly of epidote with a few scattered grains of pyroxene. The pyroxene is probably diopside as indicated by the earlier identification (loc. cit.). One can describe this rock as an epidotoic pyroxene-hornblende-schist. There is one area in England, and as far as I know only one, from which rocks of this character have been described. They occur in the Landewednack schists in the Lizard district of Cornwall. The dominant rock in these schists is a dark green, almost black, hornblende-schist but there are, in the hornblende-schists, many lenticles and bands of yellow epidote and in places these epidotic streaks are very thin and give the rock a banded and variegated appearance. It is with these epidotic hornblende-schists that I find the material of the Dorchester mace-head closely comparable. The Geological Survey Memoir (1946, pp. 45-46) mentions several localities round the coast at which they outcrop, namely: Bass Point and Landewednack, Church Cove and Cadgwith, the Porthoustock district, and along the cliffs at Porthallow. There are very few good exposures of them inland, but they have been recorded at 'occasional exposures in the roadsides and in the banks of streams . . .' (G. S. Mem., p. 48) in a belt running round the northern edge of Goonhilly Downs from Porthallow in the east to Mullion on the west coast. I have examined thin sections of specimens of these epidotic hornblende-schists in the Geological Survey Collection and of specimens from Church Cove and Cadgwith collected for me several years ago by Captain A. K. Totton. There is no doubt that their mineral components are the same as those of the Dorchester mace-head, viz. hornblende and pyroxene, sometimes with feldspar and epidote, and accessory sphene. Even the turbid grains, which I have tentatively suggested are feldspar, are present in the Cadgwith specimens and are exactly like those in the section of the mace-head. The amount of epidote varies and some of my sections show less of this mineral than the Dorchester mace-head does, but mineralogically the mace-head and the epidotic hornblende-schists are a good match. The only doubt I had about the match was that all the specimens I saw in 1957 in the Geological Survey Collection and in our own showed very flat parallel bands. None showed the contorted folds as seen in the mace-head. However, the Geological Survey memoir recorded 'streaky, undulating or contorted epidotic banding on the beach at the north side of the cove' [Cadgwith] and sharply folded epidotic hornblende-schists are figured from Church Cove quarry (G. S. Mem., p. 46, and


This paper proposes a simple, fairly general, test for global identification of unconditional moment restrictions implied from point-identified conditional moment restrictions. The test is based on the Hausdorff distance between an estimator that is consistent even under global identification failure of the unconditional moment restrictions, and an estimator of the identified set of the unconditional moment restrictions. The proposed test has a chi-squared limiting distribution and is also able to detect weak identification alternatives. Some Monte Carlo experiments show that the proposed test has competitive finite sample properties already for moderate sample sizes.

ABSTRACT Squeeze-out transactions are controversial as the controlling shareholders may expropriate the minorities' shareholdings at unattractive prices. Existing scholarship has focused on the optimal approach towards regulating such transactions in the United States (US) and the United Kingdom (UK), which have widely dispersed public shareholdings, but little attention has been placed on jurisdictions with concentrated shareholdings, which may necessitate a different approach given that the prospects of expropriation are very high. This article fills the gap by examining Hong Kong and Singapore, which have concentrated shareholdings. Notwithstanding the fact that they have adapted their corporate and securities laws from the UK, Hong Kong ultimately provides greater minority shareholder protection than Singapore. We present empirical evidence that the differences in regulation have led to a smaller number of squeeze-outs but higher premiums payable to minority shareholders in Hong Kong, as compared to Singapore. However, Hong Kong firms experience higher levels of related party transactions prior to the squeeze-outs, which represent another form of tunnelling. We explain the differences in regulation and discuss the normative implications of our findings. Our study contributes to the broader literature that 'law matters' and provides case studies of how interest group politics shape the evolution of laws and regulation.


More than 30% of adults and 15% of children in the United States are subject to increased disease burden and shortened life span as a result of obesity. 1,2 Wide-spread fast-food consumption, 3-6 increasingly sedentary lifestyles, 7,8 and ubiquitous television viewing 9-11 have created a complex cultural fabric whose unraveling is vital to our understanding of the epidemic of obesity. For children, these cultural changes have been mirrored in the school environment where vending machines and soda sales are becoming commonplace, and physical education classes are increasingly becoming a thing of the past. 12-14 Since adolescent overweight and obesity are highly correlated with adult obesity, there are growing public health efforts aimed at improving the nutritional content of children's diets, establishing healthy eating habits at a young age, and decreasing sedentary behavior.


AbstractThe equipment described consists of a micro-camera, and a flash tube unit. The micro-camera embodies a single leaf electromagnetic shutter. The leaf is inclined, and the lower side is silvered to reflect the microscope eyepiece light cone Into a viewing eyepiece. The shutter is actuated by a separate foot-operated timer, giving exposures from I sec.-I 300 sec. The flash-tube is used in conjunction with the camera, to give an exposure of 5 micro-seconds. It has mercury electrodes and forms a light source 3 millimetres in diameter, of great intrinsic brilliance. Using an I ford 109 filter, 94°, of the light output, as recorded on Panatomic X film, lies within the wavelength range 5000°-6400 A. This is the corrected range for achromatic objectives. The tube operates at 950 volts D.C., and dissipates 4 joules. The light output is sufficient for 2 mm. oil immersion phase contrast and dark ground photographs.The photographic technique used by the author is described.


The utility model discloses a frictional welding manipulator which comprises an adjustable supporting seat and a rotary fictional welding mechanism sliding seat which is in positioning connection with the adjustable supporting seat. A guiding rail with an H-shaped section is arranged at the center of the rotary fictional welding mechanism sliding seat, and a rotary fictional welding mechanism is arranged on a guiding rail. The main shaft of the rotary fictional welding mechanism is provided with a column-shaped inner cavity. A sliding rod which shares the same axis with the main shaft is arranged in the inner cavity. The head part of the sliding rod is provided with cutting cools. The tail end of the sliding shaft and the tail end of the main shaft are respectively connected with a driving gas cylinder. The main shaft is driven by a motor which is arranged at the lower side of the main shaft and on the guiding rail. The utility model has the advantages that two working procedures of opening cutting and welding can be finished once. The bother of repeated assembly can be avoided. Because the direction and the height of the manipulator can be randomly adjusted, the utility model can adapt different working conditions.


It feels particularly appropriate, if not sentimental, that the much anticipated Protection from Harassment Act became effective on April 27 2013, Freedom Day. Freedom is one of the foundational pillars of the Bill of Rights and is an essential concept to our democracy.


Cognitive architectures (CA) have been historically introduced i) "to capture, at the computational level, the invariant mechanisms of human cognition, including those underlying the functions of control, learning, memory, adaptivity, perception and action" (Oltramari and Lebiere, 2012) and ii) to reach human level intelligence, also called AGI (Artificial General Intelligence), by means of the realization of artificial artifacts built upon them. During the last decades, many cognitive architectures have been realized such as ACT-R (Andersson et al. 2004), SOAR (Laird 2008) etc. and have been widely tested in several cognitive tasks involving learning, reasoning, selective attention, recognition etc. One of the open problems of such computational artefacts regards, however, the fact that they are general structures without a corresponding "general" content, able to cover the different types of knowledge available to humans and used by them in decision making processes. In other terms: the type of knowledge represented and manipulated by such CAs is homogeneous in nature. It mainly covers, in fact, only the so called "classical" part of conceptual information (that one representing concepts in terms of necessary and sufficient information, see Frixione and Lieto, 2012 on these aspects). On the other hand, the so called "common-sense" conceptual components of our knowledge (i.e. those that, based on the notions developed in the experimental and theoretical cognitive sciences, allow to characterize concepts in terms of "prototypes", "exemplars" or "theories") is largely absent in such computational frameworks. Common sense conceptual representation and reasoning, in fact, is only partially allowed by the symbolic-based formalisms and structures of the "chunks" adopted by the most common general CAs (e.g. ACT-R and SOAR), or by alternative hybrid solutions adopted by CAs such as CLARION (Sun, 2006). This aspect represents both a technological and an epistemological problem: the lack of the common-sense representational and reasoning level, in fact, affects not only the performance of artificial agents (embodied or not) based on such CAs, but also the explanatory power of the heuristics adopted within the CAs compared to the human decision making strategies (Lieto 2015). Conceptual Spaces (Gärdenfors, 2014) have been proposed as a general framework for representing knowledge and have been widely adopted in many applications and cognitive


Department of Urology, Sapporo Medical College (Director: Prof. S. Takai) A 7 years and 8 months old boy with precocious development of secondary sex characteristics and well developed external genitalia was presented. The urinary excretion of gonadotropin, 17-IBS, 17-OHCS and estrogen were under 6 muu/day, 3. 1-2. 18 mg/day, 3. 28 mg/day and 9. 0 gig/day, respectively.

Hysterectomy is the most commonly performed major gynecological surgery worldwide .The cause for hysterectomy being done varies from country to country and region to region. Hysterectomy may be total /complete, partial /subtotal /supracervical hysterectomy. The study is a retrospective analysis of 454 cases of hysterectomy specimens received in Department of Pathology ,Govt.Stanley Medical College,Chennai, Tamilnadu during a one year period from January to December 2016. The objective of this study is assess the age distribution of females undergoing hysterectomy and analyze the varioushistopathological features of uterine lesions in these specimens. In our study , the most common age group who underwent hysterectomy was 41-50 years followed by 31-40 years group and least hysterectomies were done in 71-79 years age group.Total abdominal hysterectomywith bilateralsalphingoophorectomy was the most common type of hysterectomy performed in this study. Most of lesions were myometrial 263 cases (57.9 %), cervix 89cases (19.6%), endometrium 61 cases (13.4%) and ovary 42 cases (9.2%). Hysterectomy still remains the widely used treatment modality in developed and developing countries. All hysterectomy specimens should be sent for histopathological examination regardless of the pre-operative microscopic assessment, especially in malignant disease.


Second-order corrections to the optical potential for kaonic atoms are evaluated in the form of an approximate, local potential which takes into account an isovector correlation function but omits Pauli and hard-core correlations. The corrections are found to be very small, a result not appreciably modified when rough estimates of the consequences of Pauli correlations are considered.


The natural dialectic that is generally comprehended as the dialectic of the nature has its great denotation during reversing the Hegel's idealism dialectic.However,as a conception of the theoretical philosophy framework it also exists one-sidedness of the thinking style of empirical science and traditional phisolophy's schem of the opposition between the subject and object.In fact,there exists the second way of reversing the Hegel's idealism dialectic discoveryed by Karl Marx that is the dialectic of the humanized nature.The dialectic of the humanized nature is the natural dialectic as a pratical wisdom which is the real meaning of Markism natural dialectic.

Ax interesting congenital anomaly of the middle ear was seen in a 33-year-old gardener, who was referred to our clinic on account of deafness. The disability was first noticed at the age of 7 years and had gradually worsened with age. There was no paracusis. No other members of his family have been deaf. He had been using a hearing aid for 17 years. He is a cheerful man in spite of several congenital deformities. He has deep clefts in his hands (Fig. 1). Two fingers are missing on each side. The left thumb is stunted. He is myopic with macular degeneration in both eyes. Eye operations have been performed at various times for congenital cataracts and detached retina of the right eye. There have been no congenital defects obvious in any of his relations of the past and the present generations. His birth had been normal; preand post-natal periods were uneventful. No visible abnormality was detected in his ears, nose or throat on physical examination. His tonsils had been removed during childhood. Tuning fork tests revealed bone conduction to be better than air conduction on both sides. The pure tone audiogram showed a wide air-bone gap and perceptive deafness for higher tones. The left ear seemed to be the worse of the two for hearing (Fig. 2). His speech is normal. There is no history of educational difficulties in his childhood. These two factors indicate that his deafness could not have been very bad in his childhood. Gradual worsening of his hearing could not be explained on the basis of a congenital defect of the ossicles. Otosclerosis was considered to be a more likely condition. Exploratory tympanotomy was performed on March 8th, 1965, on the left side using endomeatal incision. A tympanomeatal flap was reflected to expose the middle ear. Deliberate movement of the malleus resulted in movement of the incus and the stapes. No movement of the footplate was seen. Further exploration revealed a gap between the superstructure of the stapes and the footplate. On removal, the stapes was found to consist of a head, a neck and a small, atrophic anterior crus. There was no posterior crus. The footplate covering the oval window was very thick and fixed resembling stage IV in otosclerosis (Portmann, Portmann and Claverie, 1964). The facial nerve was following an abnormal course. It ran along the lower border of the oval window being embedded in the promontory and clearly visible through its thin bony cover. No other abnormality was seen in the middle ear. Photographic record of these findings could not be made owing to the lack of the necessary equipment. A hole was drilled through the thickened footplate and a teflon piston was inserted. The tympanomeatal flap was replaced to close the middle ear.

At present, selenium is known to be a normal component of several enzymes, proteins, and some aminoacryl transfer nucleic acids. Certain selenium compounds have been reported to possess anticarcinogenic properties, slow the aging process, strengthen the immune system, enhance the sexual functions, etc. In order to understand the role of selenium in human and animal metabolism, analytical methods of high precision and accuracy and of excellent sensitivity are being sought. Neutron activation analysis (NAA) has many advantages that can be exploited for determining selenium. In general, instrumental NAA (INAA) is sensitive enough for the determination of selenium in most biological materials. The determination of very low levels of selenium, e.g., less than 30 ppb, in the presence of large amounts of interfering elements such as sodium, bromine, chlorine, etc., can be facilitated by preconcentration NAA. The technique can also provide superior precision.


Echoes obtained with a monostatic acoustic sounder have to date been attributed largely to random thermal structure in the atmosphere. A dependence of echo strength on the sound beam zenith angle has now been verified for certain highly stable conditions in the planetary boundary layer. Maximum returns are obtained with a vertically pointed beam. The regions of strong return correlate spatially with temperature striations which are essentially horizontal. Measured microthermal structure of such inversion layers can account for the excess or Fresnel acoustic reflection observed. This excess echo may be several times stronger than scattering from random thermal structure. Examples of simultaneous returns at zenith angles of 0° and 45° are presented, and the theory of normal acoustic reflection from realistic temperature inversions discussed.


This paper presents an efficient mobile POS (point of sale) system-one that will not cripple an entire company that happens to the business. Another goal is to make an easy-to-understand user's interface (UI) and allow for improvements to be made easily based on the needs of the business owner. The former will be accomplished by creating a web-based POS, which means that the only thing limiting the system is the access of the internet. Outages and "down time" are virtually non-existent with proper management. The latter will be assessed in the actual formation, using a minimalistic format which can easily be tailored to the needs of the user. The benefits of using this sort of POS go far beyond simply improving the user experience and minimizing technical errors; businessmen that have to interact with clients on-the-go will be able to easily access the system all the same, allowing for some much needed flexibility in small businesses.


Abstract Non-steroidal anti-inflammatory drugs are the conventional treatment for pericarditis. However, some patients will still suffer from persistence pericardial effusion despite exhausting all conventional management options. A 4-year-old girl with idiopathic pericardial effusion who did not respond to 2 months of conventional therapy had complete resolution of effusion within 5 days, with no recurrence after administration of intrapericardial steroids. As far as we know, this is the first published paediatric case who has shown a similar outcome to that seen in adult studies.


With the globalization process,more and more cities have entered the competitive global market.Cultural diversity also has turned out to be an effective tool to position the city in the world city system.Over the past decade or so,disadvantaged,multicultural districts of cities in Europe have been selected,developed and marketed as new destinations for leisure and tourism.Similar changes have also observed in China in which cities are often dominated by Han culture.Since the opening policy,the ethnic communities increased at a very rapid time and the urban tourism further provides them opportunities for them to promote their cultures in cities.This study attempts to understand the role of tourism in shaping the presentation of cultural diversity in Chinese cities.It is expected the study will raise attentions for further researches on this area.

How the U.S. Can Help the Algerians Fight the Battle against Violent Islamic Extremists? Algeria is a country generally misunderstood by many Americans both in the policies of its Government and in the writings of her scholars. Algeria's geographical location along the north coast of Africa can be seen as a metaphor for its dilemma; it is considered as part of the Mid-East when convenient, as part of Africa when necessary, and yet it is physically closer to Europe than to the Levant. Fighting terrorism intermittently since its birth 60 years ago, Algeria has served as a test case both for those who use terrorism as a tactic and also for those who must respond to this tactic. It is this unique situation, coupled with the globalization of terrorism, that puts Algeria at a precarious crossroads from which it can progress into the modern world or regress into the chaos of uncontrolled terrorism. While the people of Algeria anxiously await a glimpse of the path that their country will take at this crucial juncture, we in the West, particularly in the United States, must ask ourselves two questions: How can we help, and what can we learn? To understand how the U.S. can help Algeria combat violent Islamic extremists, the U.S. must first understand Algeria's history. Algeria's fight against modern terrorism began in 1957 when the National Liberation Front (FLN) rose up against French colonialism. The FLN drove the French from Algeria and the nation achieved independence in 1962. During the next three decades Algerians endured coups d'etat, corruption, and violence until reaching a watershed event in 1991 when the Islamic Salvation Front (FIS), a loose coalition of Islamic political groups, was poised to win the parliamentary elections. Instead the Algerian military cancelled the elections, sending the nation into a bloody civil war in which thousands of people lost their lives. The (now banned) FIS party's first order of business was to re-write the Algerian constitution, abolishing democracy and replacing it with a theocracy based on Sharia law. The success of the FIS had less to do with the Algerians desire for a theocracy and more to do with their disenchantment with the corrupt, ruling FLN. While cancelling the elections was surely not in keeping within the ideals of a democracy, in the long term this action probably saved Algeria from a worse fate of decades of violent extremist oppression similar to the Taliban rule in Afghanistan. The aftermath of the cancelled elections was a decade of full scale terrorism, which began to subside early into the 21st century. Unfortunately this peace did not last long. Within the last few years, terrorism in Algeria has re-emerged as part of a globalized movement tied to the international jihadi movement. The recent rise of terrorism in Algeria, dating from 2006, can be directly attributed to the global escalation of violent Islamic extremism and the rise of Al Qaida (1). While conducting war is a necessary component of the comprehensive fight against violent Islamic extremism, there are more parts to the fight than military action alone; this article concentrates on those other components. The following are twelve suggestions for the U.S. Government regarding how to aid Algeria in its fight against violent Islamic extremism. They range, in order, from a broad globalized scope to a narrow scope tailored specifically to Algeria's circumstances. Some of the suggested points are aimed at decreasing global terrorism trends in general, (which, in turn, will decrease terrorism in Algeria) while others are directed towards Algeria's unique situation. Many of the changes suggested in this article are changes to the way the U.S. approaches foreign policy. These changes are not simply to improve relations with Algeria or Arab nations but to facilitate favorable relations with all nations. Certain themes prevail throughout these suggested changes: respect for other nations, observance of international law, and adherence to American values are suggestions that will not only aid Algeria but also the U. …

Drach, B. Olijnyk, M Vingranovskiy, L Kostenko. The types of referential semantization of these pronominal units are defi ned and pecularities of their content fullness through the prysm of each poet's psychological type are revealed.


Landscape maintenance plays an important role in ensuring the landscape sustainability of recreational forest. Proper landscape maintenance can enhance park's quality as well as increase user experience in the park. As new recreational forests are developed, the need for good landscape maintenance and management geared towards sustainability is crucial. The goal of this study is to understand users' perception towards recreational forest landscape maintenance and management. The objective of this study is to analyze users' perception towards landscape maintenance of recreational forests in relation to their existing management programs, and to discuss implications of maintenance and management of recreational forest towards sustainability. The study is conducted at three selected recreational forests in Selangor, namely Sungai Tekala Recreational Forest, Sungai Chongkak Recreational Forest and Templer Recreational Forest. A total of 533 respondents participated in this study. Results indicate that the present landscape maintenance standards of these sites are low reflecting weaknesses in the management system. Therefore, the management team of these recreational forests must improve their landscape maintenance and management approaches for sustainability including improving users' convenience, safety and experience.


Magnetic Flux leakage(MFL) testing technology is widely used to detect the corrosion defects of the oil and gas pipelines on-line.The traditional 1-D MFL testing technology is usually employed to measure the leaked field in the direction of radius and can only characterize the depth of the defect.For arbitrary-shaped defects,it is ineffective.To characterize the irregular defects and enhance the capability of inspection,the 3-D MFL testing technology is required.There is substantive signal to be sampled and processed in the 3-D MFL measurement system,and hence the system is relatively complicated.In this paper,we present a 3-D MFL measurement platform,in whicha significantly simplified scheme of data acquisition is proposed.In the platform,the 3-axis MFL signal is sampled,transmitted and stored via the RS-485 bus at high speed,and the baud rate of the bus is up to 6.125Mbps.The experimental results show that the proposed platform is efficient in the 3-D MFL data acquisition,and enhance the capability of inspection.
