This paper discusses the role of zakat organizations as the emerging Third Sector in Indonesia. It presents the profiles of three currently leading zakat organizations: Rumah Zakat Indonesia (RZI), Dompet Dhuafa (DD), and Pos Keadilan Peduli Ummat (PKPU). This paper highlights that the zakat organizations play an important role in serving public needs in Indonesia. They offer many services in such areas as health, economy, education, agriculture, and disaster reliefs. Competition does exist among zakat organizations, particularly if they operate in the same areas and target the same segment of donors (e.g., wealthy Muslims in urban areas). This paper argues that some more efforts are still needed to strengthen the roles of zakat organizations as part of the Indonesian third sector. This could be achieved through strengthening the accountability and the transparency of zakat management as well as by encouraging zakat organizations to allocate more funds for economic development programs. Allocating more funds for economic development programs would make zakat organizations more powerful in promoting social welfare in the society.


All ships make good use of the satellite transportation system to communicate external as well as internal data understanding on the sea. At that time, there is diverse kinds of information to communicate one another such as voice, letter, picture and video on the sea to sea, sea to ground. In addition, there are other means to share information like a sign, voice, message, picture and video shared between vessels and ground units. Although the ships utilized FDMA in the initial stage of the satellite procurement, MF/TDMA method is recently applied as means to transmit information. Both FDMA and MF/TDMA, however, are not the best means of data transmission as the number of bandwidth is limited for both methods. Thus, in order to provide a solution for this problem and to see how the amount of transmission increases, a research on applying MF-TDMA + SCPC has been conducted for the Navy's satellite communication system for the efficiency of the satellite network within the original frequency bandwidth will be maximized through the application of digital transformation methods and Roll OFF Factor as a means of data transmission.


Cropley, Kaufman, and Cropley (this issue) make an important contribution in arguing for the value of creativity for terrorism prevention. Their message will be, though, somewhat more novel for scientific researchers and theorists than for the intelligence and security communities. It also leaves out many concepts and techniques, from the Psychology of Creativity literature, which are relevant to the theme of preventing terrorism. In this article, we give some attention to examining the constructs and analyses presented by Cropley et al. Most of our effort is, however, devoted to using Cropley et al.'s ideas as the starting point for a more detailed discussion of applying cognitive psychology, social psychology, organizational psychology, and security-profession ideas to creatively anticipating potential creative terrorism attacks, and devising creative counter-measures against such attacks. To illustrate the potential application of the Psychology of Creativity to terrorism, results are presented of a pilot study on using the Red-Team/Green-Team, Attack-Defense Tree, and Nominal Group techniques to generate possible creative approaches to anticipating and countering terrorism.


In this insightful and provocative book, Sergeev creatively takes the reader through the world religions, with a remarkable and easytounderstand table of comparisons at the end. It shows not only his deep interest in religions but also a fair and accurate understanding of the Bahá'i Faith, which takes up a major part of this book. He takes the reader through the movement of modernity and enlightenment and comprehensively compares religions to each other and all of them to the Bahá'i Faith, the newest world religion. His explanation of modernity and its nonsectarian origin in chap. 3 is precisely accurate and easy to understand. His theory of religious cycles and the interfacing of elements of enlightenment with all past religions and the newer Bahá'i Faith take the reader through a journey of humanity through all ages, seeking truth and understanding with a reliance on faith and a mission. His theory of religious cycles is original and insightful, and it encompasses the commonality of humanity. He begins by saying: "It is not my intention to discover the origin of religion or reduce it to other forms of social activity. As a unique human enterprise, religion meets certain needs that no other social institution can adequately satisfy. It provides a sense of morality, duty, community, and meaning to life. Religion will always exist because it speaks to the peculiarity of human condition— the awareness on one's own mortality without any certain knowledge of what awaits us after death" (p. 4). He puts the reader's mind at ease about having to decide which religion is a better choice; instead, one can read with excitement and an appetite of discovery. Sergeev calls the "Theory of Religious Cycles" the recognition of all religions of the past and the Bahá'i Faith through their scriptures. He creatively lays out six phases that religions have gone through: formative, orthodox, classical, reformist, critical, and postcritical. When a sacred tradition is challenged by structural crisis, it shakes the foundation of the system that allows its evolution into a new movement or faith. Sergeev has explained well the development and reason for humankind to gravitate from an old to a new faith.


The application of Transfer matrix method (TMM) ranges from linear/nonlinear vibration, composite structure, and multibody system to calculating static deformation, natural vibration, dynamical response, and damage identification. Generally TMM has two characteristics: (1) the TMM formulae share similarity to the chain mechanics model in terms of topology structure; then TMM often is selected as a powerful tool to analyze the chain system. (2) TMM is adopted to deal with the problems of the discrete system, continuous system, and especial discrete/continuous coupling system with the uniform matrix form. In this investigation, a novel TMM is proposed to analyze the natural vibration of the tree system. In order to make the TMM of the tree system have the two above advantages of the TMM of the chain system, the suitable state vectors and transfer matrices of the typical components of the tree system are constructed. Then the topology comparability between the mechanics model and its corresponding formulae of TMM can be adopted to assembling the transfer matrices and transfer equations of the global tree system. Two examples of natural vibration problems validating the method are given. The formulation of the proposed TMM is mathematically intuitive and can be held and applied by the engineers easily.


This article presents an automatic video editing method for video stream selection in a multi-camera environment. The specific context of this study is council meetings recording and broadcasting. In order to offer the best view to spectator our method is based on a speaker detection, to select the right camera. Since no sound information is available, the proposed method is based on the detection of the change in the visual state of the microphones LED in image sequences, in order to automatically and efficiently select the camera where the speaker is. Studies about the suitable size of the used sliding window and about the relevant features' selection for the verification of microphones' activation are also presented. We have selected seven features to effectively train one classifier, which can be used on different cameras. The feasibility of this approach is shown by the experimentation on councils' videos where the proposed method allows a very efficient detection of the speaker in real-time.


The DC solenoid electromagnet can change its own displacement through the change of the magnetic field and then perform the corresponding action, and is widely used in underwater equipment. The electromagnetic force of the electromagnet in the working range is its important performance, but due to the nonlinear characteristics of the magnetic field, there is no unified and effective optimization design method. Aiming at this problem, this paper proposes an electromagnet optimization algorithm based on ant colony optimization algorithm (ACO) and simulates it based on ANSOFT software. The simulation results show that, compared with the conventional design method, this method can effectively improve the suction force of the electromagnet.


As the global energy needs grow, there is increasing interest in the generation of electricity by photovoltaics (PVs) devices or solar cells - devices that convert sunlight to electricity. Solar industry has seen an enormous growth during the last decade. The sale of PV modules has exceeded 27 GW in 2011, with significant contributions to the market share from all technologies. While the silicon technology continues to have the dominant share, the other thin film technologies (CdTe, CIGS, a-Si, and organic PV) are experiencing fast growth. Increased production of silicon modules has led to a very rapid reduction in their price and remains as benchmark for other technologies. The PV industry is in full gear to commercialize new automated equipment for solar cell and module production, instrumentation for process monitoring technologies, and for implementation of other cost-reduction approaches, and extensive research continues to be carried out in many laboratories to improve the efficiency of solar cells and modules without increasing the production costs. A large variety of solar cells, which differ in the material systems used, design, PV structure, and even the principle of PV conversion, are designed to date. This special issue contains peer-reviewed papers in the recent developmentsmore » in research related to broad spectrum of photovoltaic materials and devices. It contains papers on many aspects of solar cells-the growth and deposition, characterization, and new material development.« less

The current study was carried out during the two consecutive winter seasons of 2019/2020 and 2020/2021 at the Experimental Farm of Ash-Shoubak University College, Jordan, as a pot experiment. This experiment was planned to evaluate the impact of various soil salinity levels (1.17, 3.34, 6.51, and 9.68 ds/m) and amino acid types (control, L-tryptophan acid at 100 ppm, glutamine acid at 200 ppm, and L-tryptophan acid + glutamine acid) as well as their combinations on growth, salt resistance index, and some of the chemical constituents of rosemary plants. The obtained results indicated that plant height and the total herb dry weight of rosemary, the salt resistance index (SRI), and the total chlorophyll in leaves were discernably reduced with increasing soil salinity levels compared with the control. However, salinity enhanced leaf proline content. Each amino acid or its mixture improved plant growth, chlorophyll content, and SRI parameters. The SRI percentage of R. officinalis enhanced to more than 100% under a soil salinity level of 1.17 ds/m, combined with amino acids at any type, when compared with the other combination treatments. Furthermore, GC/MS showed that the identified compounds ranged from 98.39% to 99.18% and the unidentified compounds from 0.82% to 1.61% from the volatile oil of rosemary plants. The major constituents of volatile oil samples were camphor (34.95% to 40.21%), D-verbenone (13.74% to 15.23%), and α-pinene (13.21% to 16.73%).


It is an open problem whether weak bisimilarity is decidable for Basic Process Algebra (BPA) and Basic Parallel Processes (BPP). A PSPACE lower bound for BPA and NP lower bound for BPP were demonstrated by Stribrna. Mayr recently achieved a result, saying that weak bisimilarity for BPP is $\Pi_2^P$-hard. We improve this lower bound to PSPACE, and, moreover, prove this result for the restricted class of normed BPP. It is also not known whether weak regularity (finiteness) of BPA and BPP is decidable. In the case of BPP there is a $\Pi_2^P$-hardness result by Mayr, which we improve to PSPACE. No lower bound has previously been established for BPA. We demonstrate DP-hardness, which, in particular, implies both NP and co-NP-hardness. In each of the bisimulation/regularity problems we also consider the classes of normed processes. Finally, we show how the technique for proving co-NP lower bound for weak bisimilarity of BPA can be applied to strong bisimilarity of BPP.

The paper concentrates on the study of reflection and transmission characteristics of waves at the interface of a thermoelastic-diffusive solid half-space underlying an inviscid liquid. The analytic expressions for amplitude ratios, reflection and transmission coefficients, in terms of incident angles and material parameters have been obtained for quasi-longitudinal (qP) and quasi-transverse (qSV) wave incidence. The normal and grazing incidence cases have also been derived and discussed. The total reflection phenomenon has also been discussed. The energy law has been shown to be obeyed by the incidence, reflected and transmitted waves by deriving energy equation and its simulation. The numerical computations of reflection and transmission coefficients have been carried out for copper material half-space in contact with water at the interface by using MATLAB software. The computer simulated results have been presented graphically in order to bring out clear comparison of various situations.


Levothyroxine is one of the most commonly prescribed drugs. A common reason for levothyroxine treatment on patients with subclinical hypothyroidism are depressive symptoms. A meta-analysis of four RCTs (n = 278) found no benefit of levothyroxine therapy on depressive symptoms. However, the confidence interval does not exclude a small clinical benefit. We aim to assess the effect of levothyroxine therapy for depressive symptoms in patients with subclinical hypothyroidism using data from a RCT with more than 400 adults.

 The TRUST trial was a double-blind, randomized, placebo-controlled trial involving adults aged ≥65y with subclinical hypothyroidism (elevated TSH levels (4.6-19.9 mU/L) and free thyroxine within the reference range). The outcome was depressive symptoms after 12 months based on the Geriatric Depression Scale (GDS-15), a 15-item questionnaire (range: 0 to 15, higher scores indicate more depressive symptoms, minimal clinical important difference: 2). The multivariable linear regression model was adjusted for levothyroxine starting dose, sex, site, and GDS-15 baseline score.

 425 Swiss and Dutch adults with subclinical hypothyroidism were randomised (mean age 75y, 56% female). The mean (SD) TSH was 6.6 (2.1) mU/L at baseline and after 12 months decreased to 3.8 (2.3) mU/L in the levothyroxine group vs 5.9 (2.7) mU/L in the placebo group. At baseline, the mean GDS-15 score was 1.3 (1.9) in the levothyroxine group and 1.0 (1.6) in the placebo group. The mean GDS-15 score at 12 months was 1.4 (2.1) in the levothyroxine and 1.1 (1.7) in the placebo group with an adjusted between-group difference of 0.2 for levothyroxine vs. placebo (95% CI:-0.1 to 0.5; p = 0.29).

 In this by far largest RCT on the topic, levothyroxine therapy did not confer a benefit for depressive symptoms. Consequently, our results do not support the practice of prescribing levothyroxine for depressive symptoms when they co-occur with subclinical hypothyroidism.

 Levothyroxine has no benefit on depressive symptoms in patients with subclinical hypothyroidism. Levothyroxine prescription to patients with subclinical hypothyroidism and depressive symptoms should be reconsidered.


This paper describes the fast image display of the Sheffield Real-Time Electrical Impedance Tomograph. The display uses standard Transputer-based graphics hardware driving a CRT video monitor. It produces a large, interpolated, movie display on the CRT screen at 25 images per second, and is capable of operating several times faster than this.


: This study describes that light flicker of LED lamp is improved by placing an AC-powered LED block in each phase of three-phase AC power. Rectified current is considered as an instantaneous luminous flux because the current flowing through the LED block is proportional to the amount of light emitted by the LED block. Percent flicker is calculated simply by modeling the rectified current flowing through the LED block to a triangular wave current. Percent flicker is 100% in single-phase AC powered LED lamp. Percent flicker of the same level as that in an incandescent lamp (6% ∼ 14%) is however, achieved if light emission starts before 40° in each voltage phase of three-phase AC power.

A system model of EPS is established for the steering feel of EPS,and the current dominance part is regarded as a black-box.Firstly steering feel function is put forward and on the basis of the function the characters of the system is analyzed.The function expression of the black-box is sought in reverse aiming at system characters and frequency domain and the time domain are also analyzed.The analysis shows that the transferring function of the steering feel of EPS is bi-rank function.The black box can be designed as a PD block.The simulation results show that comparing with the proportional controller,the PD controller can greatly improve the stability,resonance peak and overshoot and speediness of the system,and the steering feel can also be enhanced.Meanwhile ground information can be copied into the turning wheel very well so that the driver can have good steering feel.


A laboratory experiment was designed to test the effect on a budget officer's allocation decisions of the characteristics of unit managers responsible for screening and proposing investment projects. A manager's total allocation was found to increase with his average actual profitability, his level of attempted influence, and his capacity to estimate costs and profits accurately. Deviations from economic efficiency (a larger allocation to the high profit manager) were greatest when attempted influence was high and when estimates of profitability were biased upwards. Implications for the design of organizational budgeting systems are discussed.


Summary

The convective flow pattern beneath the oceanic lithosphere is strongly influenced by the movement of the lithospheric plate on top. Assuming upper mantle convection, the wavelengths, geometric structure and time of onset for ridge-perpendicular rolls as functions of the Rayleigh number and the plate velocity have been investigated by numerical modelling. The related gravity anomalies have been estimated and compared to observations from the SE Pacific, which show ridge-perpendicular anomalies with wavelengths of 150–220 km and amplitudes of about 10 mGal. For constant viscosity, the type of secondary circulation perpendicular to the diverging ridge depends on the relation between imposed plate velocity, vs, and maximum velocity in the free-convection case, vHfree. If vs is less than vHfree the flow is dominated by off-ridge up- and downwellings; if vs is about 10 times larger than vHfree the flow remains 2-D. If vs is between these extrema, a chain of ridge plumes develops from the lower thermal boundary layer with adjacent ridge-perpendicular walls that lead to roll-like circulation ('Richter rolls') throughout the model box. The wavelength of these rolls is a function of the Rayleigh number and the plate velocity. For parameters realistic for the Earth, rolls with considerable amplitude first develop after more than 50 Myr with wavelengths of at least 250 km. For temperature- and pressure- (depth-) dependent viscosity, the wavelengths of the evolving rolls are determined by the Rayleigh number related to the maximum viscosity in the interior of the convecting system (and not to the average viscosity). For models with a strong decrease in viscosity to values of about 1019 Pa s in a 100-km-wide asthenospheric channel below the lithosphere, ridge-perpendicular rolls, which only fill the low-viscosity layer, appear after a few million years. After a transitional stage of some tens of millions of years rolls in the whole upper mantle also evolve. The asthenospheric rolls develop from instabilities of the upper thermal boundary layer and have wavelengths of about 220–280 km. The time needed for alignment of these rolls to the direction of plate movement is a few million years and the distance from the ridge to the point of onset of the rolls is about 200–500 km; both are functions of the plate velocity.

While the formation time for rolls in the whole upper mantle is quite large and their existence is related largely to two-layered convection, this type of flow might not be very relevant for the Earth, although it has been used to account for 3-D structures at oceanic ridges. To explain the observed gravity anomalies in the SE Pacific, roll-like circulation in a low-viscosity asthenospheric layer is the preferred candidate, where the modelled amplitudes and wavelengths of gravity anomalies fit the observations.


The profound poetic renditions, of Emily Dickinson, one of America"s most prolific and original poets, are replete with manifest commendations of the paradoxical ecstasies of an agonizing renunciation. Hence, a number of readers, like Richard Wilbur and others, have considered "Sumptuous Destitution" as the most significant leitmotif of her art. Simultaneously, Dickinson happens to be an inebriate of air, and perhaps since she writes in a trance caused by such inebriation, she is often rapacious, splenetic and covertly or overtly intransigent. The expression "Sumptuous Destitution" sounds daunting, and almost presumptuous, since it implies a certain amount of voluptuousness (the term having unequivocal implications though) that she is willing to indulge in, even in her penury. A divergent array of predicaments in describing female selfhood in and through language is demonstrated in her oeuvre. Her poems thematizing love are distinguished for their exceptional ingenuity. But, both love and poetry bring for Dickinson a calamitous end. Her love poems are seldom considered as objective demonstrations in relation to the form of traditional lyric poetry. It is these artistic nuances of her female subjectivity and her amorous sensibility that the paper seeks to uncover by a close examination of selections from her verse.


Multi-award winning record producer Mark Optiz, who has worked with The Divinyls, The Angels, AC/DC and many other legendary Australian artists was quoted by The Canberra Times, "This recording facility rates with any international recording facility I have ever worked in." "It is not just design and this fabulous Neve console, but this university has one of the best microphone collections I have ever seen."


To asses the requirement of interleukin (IL)‐10 for peripheral CD4 T cell tolerance, the IL‐10 knockout (KO) was introduced into a T cell receptor‐transgenic mouse model (TCR1) specific for SV40 T antigen (Tag). IL‐10‐deficient TCR1‐transgenic mice failed to establish antigen‐specific T cell tolerance following sequential injections with Tag peptide. Nevertheless, IL‐10 was not required for the establishment of CD4 T cell tolerance in double transgenic RT2/TCR1 mice in which Tag is expressed endogenously under control of the insulin promoter. However, in contrast to stable anergy in wild‐type RT2/TCR1 mice, tolerant T cells in RT2/TCR1/Il‐10KO mice could be driven into vigorous proliferation by exogenous antigenic stimulation in vivo. The observed reactivation of anergic T cell populations in IL‐10‐deficient mice was only seen after in vivo but not in vitro peptide priming, reflecting an important regulatory function of IL‐10 in the context of the living organism. Taken together, these results demonstrate that IL‐10 is required to maintain T cell tolerance following exposure to enhanced antigenic stimuli but is not essential for the induction of self‐tolerance.


Generating 3D garment model via 2D patterns has been investigated for years. Many outstanding algorithms have been proposed and adopted by commercialized CAD systems. However, there is no feasible way to generate the 3D garment without providing the 2D patterns for sewing. In this paper, we propose a novel approach in making 3D counterpart of the real garment via the photos taken from the front view and the back view respectively. The original photos are transferred into the so-called `meta-patterns', and then these meta-patterns are sewn and draped along the shape of the avatar to generate the 3D garment. Various techniques including two-stage numerical integration, dressing-onto-template-layer, cylindrical mapping and sewing-with-transparent-pattern are required for different types of 3D garment prototyping. It is believed that this system is an effective approach in making 3D garment with satisfied visual effects and speed.


A considerable problem exists in Queensland with prematurely distressed cement treated base pavements. This paper gives a detailed overview of the management (or problem solving) process followed by the Department of Transport, Queensland when confronted with this technical problem of how to effectively rehabilitate these pavements. Of the alternatives considered, bitumen impregnated geotextile treatments have been found to provide appropriate and effective solutions and their use is now widespread throughout Queensland. The bitumen impregnated geotextile delays and/or inhibits the occurrence and propagation of cracking and provides a continuous membrane to prevent moisture ingress and the pumping of fines from the pavement structure, thereby minimising further deterioration.


INTRODUCTION
This study investigated the protective effects of antcin C against cerebral haemorrhage injury.

MATERIAL AND METHODS
Cerebral haemorrhage was treated with antcin C 100 mg/kg i.p. at 60 min after the induction of cerebral injury. Neurological scores and volumes of cerebral injury were assessed to determine the effects of antcin C, based on oxidative stress and serum mediators of inflammation by ELISA. qRT-PCR was used to estimate the mRNA expression of Toll-like receptor 4 (TLR-4) and interleukin-1 receptor-associated kinase 4 (IRAK4) proteins in the cerebral tissue of rats with cerebral haemorrhage. Western blot assay and histopathology were also performed.

RESULTS
The findings suggest that treatment with antcin C reduced the neurological scores and volumes of cerebral injury in cerebral injured rats. Parameters of oxidative stress and cytokine levels were reduced in the serum of the antcin C-treated group compared with the negative control group. Treatment with antcin C ameliorated the expression of TLR-4, IRAK4, and zonula occludens-1 (ZO-1) proteins in the cerebral tissue of cerebral injured rats.

CONCLUSIONS
The results revealed that treatment with antcin C protected against cerebral haemorrhage damage by controlling microglia inflammation through the TLR-4 pathway.


The challenge of addressing illicit substance use and substance use disorders is not unique to one country. All scholars must consider the unique environments and cultural contexts of substance use in the approximately 196 recognized countries in the world. Often, an intervention to address substance use in one country may not work in another; national policies may also impede or facilitate identification, prevention, and/or treatment of substance use disorders. Even within countries, different ethnic cultures appear to have divergent patterns of substance use and associated problems. Interventions on substance use may need to be unique to the nationality or culture to which they are applied. For example, tailored approaches may be needed to prevent and address unhealthy alcohol use in US Hispanic and American Indian populations. 1–6 It is incumbent on scholars in the addiction field to disseminate the often disparate evidence base regarding interventions for substance use based within the context of the political and socioeconomic environments of different countries and the cultural norms of the population.


Objective: To investigate the role of ribosomal protein S15a (RPS15a) in colorectal cancer.  Methods: The expressions of RPS15a in 120 specimens of colorectal cancer tissues and the para-cancerous tissues as well as 120 specimens of colorectal adenoma tissues were detected by immunohistochemistry. The proliferation, cell cycle and apoptosis of colon cancer RKO cells after infection with recombinant lentivirus RPS15a-siRNA were detected by Cellomics cell counting assay, colony formation assay and FCM, respectively. Results: The positive rate of RPS15a expression in colorectal cancer tissues was significantly higher than those in the colorectal adenoma tissues (86.7% vs 25.8%, P < 0.001) and the para-cancerous tissues (86.7% vs 11.7%, P < 0.001). The expression of RPS15a was significantly correlated with the TNM stage (P = 0.033) and the tumor differentiation (P < 0.001) of colorectal cancer. RPS15a silencing significantly suppressed the proliferation (P < 0.01) and colony formation (P < 0.01) of the RKO cells, induced apoptosis (P < 0.01), and arrested the cell cycle at G2/M phase (P < 0.01). Conclusion: The expression of RPS15a in colorectal cancer tissues is higher than those in the colorectal adenoma tissues and the para-cancerous tissues. Down-regulation of RPS15a expression can repress the proliferation and induce the apoptosis of RKO cells. DOI:10.3781/j.issn.1000-7431.2017.33.092


Donning sturdy shoes and a backpack and supported by a quirky fish-headed walking stick, the Anglican Bishop of Bathurst is taking a more than 200 kilometre hike from Bathurst to Dubbo in his very long stride.

It's part of Bishop Ian Palmer's attempt to take a step in the right direction and lead by example amid a financial crisis facing the Bathurst diocese.


LUNG TRANSPLANT IMPROVES HEALTH RELATED QUALITYOF LIFE AT ONE YEAR AFTER TRANSPLANT Richardson C, Blanc P, Hays S, Leard L, Golden J, Kukreja J, Singer J. UCSF, San Francisco, CA and UCSF, San Francisco, CA. Purpose of Study: Health Related Quality of Life (HRQL) is a key measure of lung transplant (LT) efficacy. Since the 2005 overhaul of organ allocation (Lung Allocation System [LAS]), however, no US study has evaluated the impact of LT on HRQL. The medical acuity of patients undergoing LT has increased dramatically under the LAS, potentially limiting the generalizability of pre-LAS estimates of HRQL to patients considering LT today. Thus, we aimed to study the impact of LTon HRQL in the LAS era. Methods Used: We performed an interim analysis of a prospective cohort study of subjects undergoing LT between 2010-12 at UCSF. Subjects completed structured surveys preand 1-year post-LT. Generic-HRQL was quantified with the Short Form-12 Physical Component Summary scale (SF12 PCS)(range 0-100; normative population mean 50±10; high scores denote better HRQL). Respiratory-specific HRQL was quantified with the revised Airways Questionnaire-20 (AQ20R)(range 0-20; low scores denote better HRQL). Changes from before to after LT were tested with paired ttests; effect sizes were also calculated. An 8-point change in SF12 PCS and 1⁄2 standard deviation (SD) change in AQ20R were defined as clinically meaningful based on standard criteria. For all analyses, subjects who died prior to one-year were assigned the worst possible scores (e.g. 0 and 20, respectively). Summary of Results: The 73 subjects included in this analysis were 52±13 years; 58% female. HRQL was markedly impaired before LT (SF12 19.0 ±8.2; AQ20R 13.2±4.7). Even after accounting for the five subjects who died, subjects reported a greater than two SD improvement in HRQL 1-year after LT (SF12 40.8±16.4; AQ20R 5.2±5.6; both p<.001).Effect sizes for change were large for both generic-(d=2.7) and respiratory-specific HRQL (d=1.7). At 1-year, 58 (79%) reported improvements in generic-HRQL and 62 (85%) reported improvements in respiratory-specific HRQL that exceeded the clinically meaningful threshold. Conclusions: Lung transplant provides substantial and significant improvements in generic and respiratory-specific HRQL. This study provides contemporary data-based estimates of the impact of LT on HRQL in the LAS era, which may be important for patients and clinicians considering LT today.


In this paper we adapt ϵ-lexicase selection, a parent selection strategy designed for genetic programming, to solve many-objective optimization problems, ϵ-lexicase selection has been shown to perform well in regression due to its use of full program semantics for conducting selection. A recent theoretical analysis showed that this selection strategy preserves individuals located near the boundaries of the Pareto front in semantic space. We hypothesize that this strategy of biasing search to extreme positions in objective space may be beneficial for many-objective optimization as the number of objectives increases. Here, we replace program semantics with objective fitness to define ϵ-lexicase selection for many-objective optimization. We then compare this method to multi-objective optimization methods from literature on problems ranging from 3 to 100 objectives. We find that ϵ-lexicase selection outperforms state-of-the-art optimization algorithms in terms of convergence to the Pareto front, spread of solutions, and CPU time for problems with more than 3 objectives.


Clock gating is a common approach for minimizing dynamic power dissipation in synchronous circuits, and it can also assist in reducing the amount of power wasted by digital circuits. The system clock signal consumes the most power in an electronics product since it is responsible for component transition states, which often results in switching power consumption. Different ways of reducing leakage power in digital CMOS circuitry are described in this paper. ONOFIC and LECTOR techniques are used in D Flip-Flops (Transmission gate and C2MOS) to reduce leakage power. Digital circuits with optimized transistor sizing based on Logical Effort Theory (LE theory) have been implemented for high performance. The above-mentioned circuits are compared in terms of average power, delay, leakage power, and power- delay product (PDP). Circuit simulations are carried out in LTSpice with 65nm PTM technology with a 0.9V power supply.


A reversible switch between superhydrophobicity at low temperature and superhydrophilicity at high temperature was fabricated by coating poly(epsilon-caprolactone) on a rough substrate, which resulted from the combination of the different adaptability of the polymer chain upon crystalline/amorphous phase transition and the optimized roughness.


Abstract We performed numerical simulations of mergers between gas-rich disc galaxies, which result in the formation of late-type galaxies. Stars formed during the merger end up in a thick disc that is partially supported by velocity dispersion and has high [α/Fe] ratios at all metallicities. Stars formed later end up in a thin, rotationally supported disc which has lower [α/Fe] ratios. While the structural and kinematical properties of the merger remnants depend strongly upon the orbital parameters of the mergers, we find a clear chemical signature of gas-rich mergers.

Neural or cortical fields are continuous assemblies of mesoscopic models, also called neural masses, of neural populations that are fundamental in the modeling of macroscopic parts of the brain. Neural fields are described by nonlinear integro-differential equations. The solutions of these equations represent the state of activity of these populations when submitted to inputs from neighboring brain areas. Understanding the properties of these solutions is essential to advancing our understanding of the brain. In this paper we study the dependency of the stationary solutions of the neural fields equations with respect to the stiffness of the nonlinearity and the contrast of the external inputs. This is done by using degree theory and bifurcation theory in the context of functional, in particular, infinite dimensional, spaces. The joint use of these two theories allows us to make new detailed predictions about the global and local behaviors of the solutions. We also provide a generic finite dimensional appr...

This study aims to disclose the interpersonal meaning in movie posters. This is a semiotic study, applying Royce's (2001) intersemiotic complementarity framework. It is to analyze visual and verbal codes in the posters. The poster is taken from the official website of Marvel Studio. They are  used as a medium for advertising the products. Based on the analysis, it can be identified that the visual contact is straighforward creating a demanding pose, a close-up mode presenting an emotional expression instead of the covered face, the frontal view emphasizing the bond of the character to the viewers, its eye-level presentation creating his equality to the on-lookers. All of this demanding pose was made clear by the situation informed by the verbal elements, that Spiderman had no way home. It is also a preview of the plot of the movie in this sequel. Thus, both semiotic elements in the poster have produced a unity of meaning, which puts the superhero as a part of the society in general, especially where he lives; he is not a different human being in spite of the super power he holds.


Three dimensional profiles of the different surface locations of ZnO thin films grown by sol-gel spin process have been generated to observe growth pattern showing the growth mechanism of the films. The results not only help in controlling the parameters in growing high quality film for application in sensing devices using ZnO but also provide some understanding in the basic growth mechanisms.


This paper discusses the meaning of qiradah contained in QS. Al-Baqarah [2]:65. The meaning of qiradah has been interpreted by the community as monkeys. Even though the word qiradah is not only interpreted in an essential way. This study aims to find various meanings of qiradah with several verses using a semiotic approach. In this study, the author uses Roland Barthes' semiotic approach, namely denotation and connotation to reveal the meaning of qiradah. To achieve this goal, this research uses qualitative methods. The results of this study conclude that: First, in the linguistic system or the denotative meaning of the word qiradah, it does not only mean monkeys, but monkeys that have no shame. Second, the system of mythology or connotative meaning. The word qiradah in this system shows not the physical meaning, but the disgraceful nature that positions a person in humiliation. the interpretation of the verses of the Qur'an related to animals needs to be developed in order to expand the study of the science of interpretation of the Qur'an in order to prove the dynamic elements of the Qur'an.

Set-asso iativity in these a hes helps programs avoid performan e problems due to a he mapping on i ts. Many programs, however, need high asso iativity for only some of their frequently-referen ed addresses and tolerate mu h lower asso iativity for the remainder of the referen es. With this variability in mind, this paper proposes an asymmetri a he stru ture in whi h the size of ea h way an be di erent. The ways of the a he are di erent powers of two, and allow for a \tree-stru tured" a he in whi h extra asso iativity an be shared. We a omplish this by having two a he blo ks from the large ways align with individual a he blo ks in the smaller ways. This stru ture a hieves miss rates omparable (on average 3% better for SPEC2000) to a onventional a he of the same size and asso iativity. Most notably, the asymmetri a he has the ni e property that a esses hit in the smaller ways an immediately terminate a esses to larger ways so that power an be saved. For the SPEC2000 ben hmarks, we found a he energy per a ess was redu ed by 17% on average. 1 Introdu tion To atta k the speed gap between pro essor and main memory, aggressive a he ar hite tures are widely employed in urrent general purpose mi ropro essors. For example, Alpha 21264 [5℄ pro essor has a 64KB, 2-way set asso iative L1 data a he and an L1 instru tion a he of the same size. Ca he design is a trade-o of many fa tors in luding hit laten y, miss rate, hip area and power onsumption. Balan ing all these fa tors results in omplex designs. In this paper we propose set asso iative a hes with asymmetri al ways. This simple te hnique is based on observed a ess behavior in set asso iative a hes and an potentially provide bene ts in three areas: hit laten y, miss rate, and power onsumption. Figure 1 shows a typi al a he organization. In this organization, ea h way is symmetri . That is, ea h set is designed to have the same number of ways. However, during a tual program exe ution, depending on the memory address mapping and memory a ess behavior, ea h set may have di erent asso iative requirements. For example, in an extreme ase, a lot of addresses may map to a single set while no address map to another. This wastes a he spa e and leads to on i t misses whi h an be eliminated if a more eÆ ient mapping me hanism were used. Figure 2 depi ts the number of misses to ea h set in a 32K dire t-mapped L1 data a he for a SPEC2000 program, gzip. This gure learly demonstrates that some sets experien e manymore misses than others. Intuitively, we ould optimize the a he behavior by assigning more ways to these sets than others.

Isobenzofuran has since its discovery proven an important intermediate in the synthesis of novel organic compounds, due to its high reactivity in Diels-Alder reactions. This thesis details the synthesis, purification and characterization of cyclophane compounds derived from a novel analogue of isobenzofuran, 5,5'-bi(isobenzofuran). Because of the relative rarity of molecules containing multiple isobenzofuran units, 5 ,5 ' bi(isobenzofuran) is an excellent candidate for study. Preliminary analysis of an additional novel analogue of isobenzofuran, 5,5'-bis(isobenzofuranyl)acetylene, is also presented.


Although counter-terrorism review often works well in the United Kingdom, challenges to realising the accountability potential of counter-terrorism review persist. In large part, those challenges reflect the persistence of exceptionalist thinking within the counter-terrorist state. This chapter zooms out from the detailed accounts given in Chapters 2 and 3 to problematise counter-terrorism review from the perspective of accountability. In doing so it dwells on four persistent challenges that emerge from the analysis of counter-terrorism review: the secret state, the abundance of executive control, the limitations of Parliament, and the absence of trust. These challenges have a serious impact on counter-terrorism review but, to a large extent, this chapter argues that their resolution may be beyond the reach of the assemblage itself.


Managing stormwater on urban surfaces with blue-green infrastructure (BGI) is being increasingly adopted as an alternative to conventional pipe-based stormwater management in cities. BGI combats water problems and provides multiple benefits for cities, including improved livability and enhanced biodiversity. The paper examines six municipality-led pilot projects from Beijing and Copenhagen, through a review of documents, site observations and interviews with project managers. Beijing's projects attempt to divert from a pipe-based approach but are dominated by less BGI-based solutions; they could benefit from more integration of multiple benefits with stormwater management. Copenhagen's projects combine stormwater management with amenity improvement, but lack focus on stormwater utilization. Reviewed municipality-led pilot projects are shown to play an important role in both testing new solutions and upscaling them in the process of developing more sustainable cities. Key lessons are extracted and a simple guideline synthesized. This guideline suggests necessary considerations for a holistic solution that combines stormwater management and urban space improvements. Key lessons for sustainable solutions include defining a clear water technique priority, targeting both small and big rain events, strengthening 'vertical design' and providing multiple benefits. An integrated stormwater management and landscape design process is a prerequisite to the meaningful implementation of these solutions. Research and documentation integrated with pilot projects will help upscale the practice at city scale.


Santoso et al, 2019. Characteristics of Edible Film with Addition of the Gambir Filtrate (Uncaria gambir Roxb) and Papaya Leaf Filtrate (Carica papaya L.). pp. 176-183. Edible film is a thin layer of biodegradable packaging made from hydrocolloid, lipid and a mixture of both and can serve as a carrier packaging for antibacterial compounds with adding gambir filtrate and papaya leaf filtrate. The objective of the research was to analyze the effect of the gambir filtrate (Uncaria gambier Roxb) and papaya leaf filtrate (Carica papaya L.) on the characteristics of edible film. The research used a Completely Randomized Factorial Design with two factors and each treatment was repeated three times. The frist factor was concentration of the filtrate Gambir (0%, 2.5% and 5%) and the second factor was the concentration of the papaya leaf filtrate (0%, 2.5% and 5%). The research showed that the concentration of the filtrate gambir significant effect on percent of elongation, antibacterial, thickness and water vapour transmission rate. The concentration of the papaya leaf filtrate significantly affected the antibacterial, thickness, percent of elongation and a pressure strength. The best treatment based on some physical and microbiological characteristics is that A 3 B 3 has a thickness 0.174 mm, percent of elongation 20%, pressure strength 90.80 (N / m 2 ), water vapour transmission rate 21.16 (gm -2 .day -1 ) and a inhibition zone for microbe 7.97 mm.


In a four month study, a design for a Proton Driver was developed as a possible replacement for Fermilab's Booster. Its optical properties are summarized briefly.


Educational efforts that are centered on understanding the development of a holistic style engineering professional, via the transformation of engineering programs at the doctoral level, are vital for the successful generation of future engineers able to meet increasingly complex societal needs. Using a primarily theoretical approach, we analyzed how nine engineering education doctoral programs addressed characteristics of a transformative learning environment using the Four Attributes of Learning Environments from the How People Learn model as the basis of comparison (Bransford et al., 1999). The nine, American university programs analyzed are unique in that they are the only doctoral programs for engineering education supported within a college of engineering identified in a national search. This analysis provides a comparative understanding of how these engineering education doctoral programs have transitioned from the traditional lecture-based culture into an environment that exists to cultivate the four interrelated attributes of successful, active learning.


The chemical consequences of neutron capture into silicon in liquid tetramethyl silane have been studied by gas chromatographic separation of products produced on neutron irradiation. The radioactivity of the Chromatograph effluent, detected with a G-M counter, was counted with a multichannel analyzer operating in the multiscaler mode, giving a histogram that could be correlated with the Chromatograph detector. From data on variation of product yield caused by scavenger, radiolysis, and change of phase, the eifects of caging anf the importance of tertiary radical formation are deduced. Uniquely high yields of dimeric products are observed in this case.


Electroless plating is a chemical reduction process which depends upon the catalytic reduction of a metallic ion in an aqueous solution containing a reducing agent without the use of electricity (1). Cahill (2) showed that the cupric ion could be reduced autocatalytically with formaldehyde in an alkaline solution. Okinaka (3 ) established that the overall reaction of the catalytic copper plating process could be represented by:


Among the existing plant families in Uzbekistan, the families with the only rarespecies do not make up the majority. Physochlaina alaica is not only a rare species,but also a plant with some medicinal properties. It is necessary to develop thenecessary and appropriate measures to maintain the sustainability of any rarespecies, and before that it is necessary to have detailed information about thespecies. The population is well aware of the medicinal properties of Physochlainaalaica but does not have sufficient information on the level of rarity. In our study,we applied its eco-biology and morphology.


In the present paper, one new generalized 'useful' information generating function and two new relative 'useful' information generating functions have been defined with their particular and limiting cases. It is interesting to note that differentiations of these information generating functions at t=0 or t=1 give some known and unknown generalized measures of useful information and 'useful' relative information. The information generating functions facilitates to compute various measures and that has been illustrated by applying these information generating functions for Uniform, Geometric and Exponential probability distributions.


Purpose: This article introduces and compares the latest TO-51 clinical dosimetry protocol to the earlier protocol, TG-21. Based on the methodology of TG-21 and TG-51, the differences in clinical dosimetry measurements for both protocols are described and performed. Finally, precautions in performing the latest protocol were listed to avoid errors in clinic. Materials and Methods: The electrometer (Keithley 35617EBS) with 0.6 c.c. Farmer type cylindricalion chamber (NE2571) and 0.04 C.c. plane parallel ion chamber were employed for the measurements. The electrometer and ion chambers were authenticated by the Accredited Dosimetry Calibration Laboratory (ADCL) in University of Texas. Varian linear accelerators Clinic6/100s/n: 358 (Photon beam energy with 6 MV) and Clinic1800 s/n:180 (Photon beam energies with 6 and 18 MV, electron beam with energies 6, 9, 12, 16 and 20 MeV) were used for output measurements. The measurement protocols were based on TG-21 and TG-51 respectively, with output doses obtained to observe the variations in the monitor unit of the absorbed dose (cGy/MU). Results: The variations of monitor unit in 6 MV photon were within 0.7% and 1.4%, 18 MV photon was 2.2%, and the average for photon energies was 1.43%. The higher the photon energy, the larger the variation, suggesting that higher photon energies produce more scatter radiation due to wider distributed energy spectrum. For the electron beam, the variations in monitor units were within 1.5 - 2.2% with the average of 1.84%, showing no dependency with the electron beam energies. The variations in electron beam output were slightly higher than the photon beam, possible reasons are the measurement points in TO-51 protocol for electron beam is different from earlier protocl, a more precise method to prescribe the relationship between the clinical beam quality and stopping power ratio of the electron beam and the plane parallel ion chamber is considered for the electron beam measurements. Conclusion: The TG-51 protocol is simple campared to TG-21 protocol as large tables of stopping power ratios and mass-energy absorption coefficients are omitted and the user does not need to calculate any theoretical dosimetry factors, hence reduces calculation errors. For convenience, worksheets encompass the measurement steps and required equipment is provided. In Taiwan, it is strongly recommended that national primary standards laboratory should be established to provide the absorbed-dose-to-water calibration factor (N)for ion chambers to avoid clinical errors and to meet the accuracy in advanced radiation therapy and dosimetry.


To the Editor:

In the February issue of Stroke , Jorgensen and coworkers1 report that treatment of stroke patients in a stroke unit (SU) compared with a general ward (GW) offers benefits on the order of odds ratios of 0.17 to 0.66. Consistently, their conclusion is that all patients with acute stroke should be treated in a dedicated SU. Moreover, their findings raise serious considerations of whether further treatment of stroke patients in GWs is ethically justifiable.

In an earlier publication of the same investigation,2 Jorgensen and coworkers described an inhospital mortality of 23% in patients treated in the SU, which was 21% lower than that in patients treated in a GW. That is in fair agreement with the findings of the meta-analysis presented by the SU Trialists,3 which depended on studies predominantly performed in the 1980s.

Logistic multiple regression analysis blew up this benefit to an odds ratio for poor outcome of 0.50 for the total stroke population and 0.17 for patients with severe stroke treated in the SU. …

The effects of diffusing elements on sound field diffuseness were investigated by subjective evaluations using binaural impulse responses (BIRs) in seating areas in a surround hall. The room acoustical parameters as well as the number of peaks (Np) and local maxima within -20 dB of the amplitude of direct sound were investigated to evaluate the diffuseness in the halls. For the listening test, stimuli were selected to explore the combination of acoustic parameters and degree of diffusion. The music signals were convolved with the measured BIRs in different listening positions. Based on the listening test, it was found that positions close to the diffusers with a high scattering coefficient were preferred by the listeners.


One way to maintain the security and confidentiality of the data and information is by using encryption and decryption. Digital image used in various fields, to store important information. Digital image stored in a computer and transmitted through a computer network and the Internet are at risk to be known, altered or destroyed by certain parties. Cryptographic techniques can be applied to protect digital images of these problems, one of them by using the Caesar cipher. Caesar cipher is a cryptographic algorithm classic works by shifting the character of a specific numerical value. To improve the security of Caesar cipher, the figures used for the shift is varied. In this study generated the application of digital image encryption and decryption using the Caesar cipher modified. The results showed that the security of digital image can be performed by a Caesar cipher algorithm, by increasing security by using a semi-random shift.

The first billion years of the Earth history is poorly understood because of scarcity of terrestrial rock records. Especially, the first 500 million years, named Hadean, is literally dark because no terrestrial rocks are preserved on the earth. To unravel the early history of the earth, it is important to study the oldest rocks rarely present in the Eoarchean terranes. Acasta Gneiss Complex (AGC), located in the western part of the Slave Province, Canada, is one of the Eoarchean terranes, and mainly consists of 3.6-4.0 Ga felsic and layered gneiss suites with minor mafic rocks (e.g. Bowring et al., 1990; Iizuka et al., 2007). The mafic rocks are distributed all over the AGC and occur as rounded to elliptical enclaves and inclusions within the felsic and layered gneisses. Although field occurrence of the mafic rocks suggests that they were formed before the formation of the precursors of the orthogneisses, their formation ages have not been determined exactly because of no magmatic zircons preserved in the mafic rocks (e.g. Mojzsis small scattering. The line with high 187Os/188Os ratios yields an age of 4273+200 Ma (MSWD=15, initial 187Os/188Os=1.83+0.74), whereas the other yields an age of 4081+320 Ma (MSWD=11, initial 187Os/188Os =0.19+0.70). Those ages are consistent with geological occurrence that the mafic rocks occur as enclaves within the 3.6-4.0 Ga felsic gneisses, suggesting that the Acasta mafic rocks were formed in the Hadean. In addition, their high initial 187Os/188Os ratios relative to those of chondrite, 0.097 at 4273 Ma and 0.099 at 4081 Ma, suggest that the Acasta mafic rocks were formed from an enriched source.


We consider several generalizations of the exponential ansatz in a rather formal way, giving several new wave functions which we call exponentially generated (EG) wave functions. There are three distinct ways of the exponential‐type generations of the wave functions, two of which are new. They are named ESAC (extended symmetry‐adapted‐cluster) wave function and exponentially generated CI (EGCI) wave function. The ESAC wave function is a simple extension of the SAC wave function and is applicable even when the Hartree–Fock reference configuration is not dominant. The EGCI wave function is a CI wave function constructed in the spirit of the cluster expansion theory. Formally, it has the merits of both the CI theory and the cluster expansion theory; for example, the upper bound nature, size consistency, and the applicability to quasidegenerate states and excited states. We then introduce several new wave functions by a multiple and mixed use of the exponential‐type operators. We call such a class of wave functions multiexponentially generated (MEG) wave functions. There are many possibilities for the MEG wave functions, and the MR‐SAC wave function proposed previously is one of them. When the system involves several classes of electron correlations, the MEG wave function permits an optimal (physically and practically) use of the exponential‐type operators for the distinct classes of electron correlations. We described the method of solution of the EG and MEG wave functions and examined size consistency and some other properties.We consider several generalizations of the exponential ansatz in a rather formal way, giving several new wave functions which we call exponentially generated (EG) wave functions.

The Event Horizon Telescope Consortium is on the verge to provide the first telescopic image of massive black holes SgrA* and M87* surrounded by accretion disks, at a resolution scale comparable to the size of their event horizons. Well before this remarkable achievement made possible by VLBI radio astronomy, many researchers used the computer to reconstruct how a black hole surrounded by luminous material would look from close-up views. The images must experience extraordinary optical deformations due to the deflection of light rays produced by the strong curvature of the space-time in the vicinity. General relativity allows the calculation of such effects, both on a surrounding accretion disk and on the background star field. This article is an exhaustive and illustrated review of the numerical work on black hole imaging done during the first thirty years of its history.


A detailed analysis of the dynamics of unstable modes present in the linearized Navier–Stokes-Fourier system in the presence of a gravitational field is carried out. The transition between the non-dissipative and dissipative regimes is explored from the mathematical point of view by considering the same equation of state in both cases, a procedure which sheds light on the discontinuity present in the critical parameter. It is also shown that two distinct behaviours for the propagation of unstable modes can be identified below the critical value for a gravitational instability to occur, depending on a parameter R that quantifies the relevance of dissipation relative to gravitational effects.


We regard the technique for correction of rotational malalignment by using a special rotational plate as safe and reliable. It facilitates difficult surgery significantly. Precise surgery with premounting the plate, correct position of the osteotomy, and early rehabilitation are key points for good clinical outcome.

Doing theology for secularised man One of the problems of theology today is how to tell the stoiy of Jesus to modern man in such a way that he still can belief in God. Paul van Buren tried to make the gospel comprehensible to modern man by making use of the verification principle of linguistic analysis, and he consequently reduced the whole of the gospel to a single content, that of freedom, around which he them thematised a theology that according to him, should be relevant. By bringing about this reduction he argued that the gospel should be stripped of all metaphysical content so that it could pass the test of verification and lay claim to truth and reality. Because he argued in terms of the logic postivism we can not accept his method. But the issue is still on the table namely: How to translate the gospel and the simbols of the church in such a way that it still can communicate with modern man. On this issue the Dogmatics is still working and by using various methods tries to find answers on this important issue.


Acquired melanocytic nevi in aesthetically significant areas, especially palpebral nevi (PN), are becoming a frequent reason for patients to seek dermatologists. Surgical methods for removal of PN are reported to be associated with the risk of such side effects as scars and loss of eyelashes.
Aim of the study. To evaluate the efficacy of the removal of PN on the eyelid area with dual-wavelength radiation of a copper vapor laser (CVL).
Patients and methods. Laser removal of medium and large-sized PN (up to 10 mm) was performed in three fair-skin female patients. The procedures were carried out at an average CVL radiation power of 0.60.8 W, at a 3:2 ratio of radiation powers at wavelengths of 511 nm and 578 nm, exposure duration 0.3 s, light spot diameter 1 mm. The treatment was carried out during one session.
Results. Removal of PN with dual-wavelength CVL radiation allowed achieving a significant lightening and reduction of the involved area, without scars. The skin healing after the procedure lasted 2 weeks.
Conclusion. The high efficacy of the PN removing in the eyelid area using the dual-wavelength CVL radiation allows the introduction of this approach into dermatologists and cosmetologists clinical practice.


How people choose among a set of options is affected both by how they evaluate each option, and how they perceive the competition among those options. For instance, separate lines of work have shown that people weigh their options differently depending on (a) how confident they are in their valuation of each, and (b) whether or not selecting one option from a set excludes the possibility of selecting others. It remains unclear whether and how these two factors interact in shaping not only choices but also how difficult it feels to make a choice. To examine this interaction, we compared typical exclusive choices to non-exclusive choices, in which participants can choose additional items from the set after their initial choice. We tested how the value a person assigned to each option interacted with their confidence in those values to shape initial choices, subsequent choices, and experiences of choice conflict. When participants were required to choose one option from a set, we found that they were more likely to choose a low-value option that they had low confidence in than one they had high confidence in, and vice versa for high-value options. However, when participants had the flexibility to continue choosing additional items or not, we found that this effect was either absent or even reversed. We also replicated previous findings that participants experience the most conflict when choosing among the most and the least valuable options, but showed that this U-shaped effect was attenuated with lower levels of confidence in one's value estimates. Our work sheds new light on mechanisms of decision-making by highlighting that the impact of value confidence on choices critically depends on whether an option needs to be chosen at all. By adding nuance to previous findings our results provide a starting point for better understanding the mechanisms underlying value-based decisions, and what makes some choices harder than others.


We report the remote growth of carbon nanowalls in a plasma beam sustained by an expanding argon radiofrequency discharge and injected with a small amount of acetylene in the presence of hydrogen as active gas. The growth process was investigated by varying the mass flow rates, ratio and nature of gases (argon, ammonia/hydrogen, and acetylene), the substrate temperature, and the radiofrequency power. Scanning and transmission electron microscopy, Raman spectroscopy, and electron diffraction methods were used for the investigation of the deposited material. We found that although materials with various morphologies can be generally obtained, nanostructured carbon material with a 2D morphology is obtained within a specific range of parameter values.

Community detection is an important information mining task in many fields including computer science, social sciences, biology and physics. For increasingly common large network data sets, global community detection is prohibitively expensive, and attention has shifted to methods that mine local communities, i.e. methods that identify all latent members of a particular community from a few labeled seed members. To address this semi-supervised mining task, we propose a local spectral subspace-based community detection method, called LOSP. A sampling technique is first applied around the seeds to significantly reduce the scale of the search. Then we define a family of local spectral subspaces based on Krylov subspaces, and seek a sparse indicator for the target community via an one norm minimization over the Krylov subspace. Variants of LOSP depend on types of random walks with different diffusion speeds, regular random walk or inverse random walk, dimension of the local spectral subspace and steps of diffusions. The effectiveness of the proposed LOSP approach is theoretically analyzed based on Rayleigh quotients, and is experimentally verified on a wide variety of real-world networks across social, production and biological domains, as well as on an extensive set of synthetic LFR benchmark datasets.


OBJECTIVE: To estimate whether administration of 17&agr;-hydroxyprogesterone caproate can prevent neonatal morbidity in multiple pregnancies by reducing the preterm birth rate. METHODS: We conducted a multicenter, double-blind, placebo-controlled randomized trial in 55 obstetric clinics in the Netherlands. Women with a multiple pregnancy were randomized to weekly injections of either 250 mg 17&agr;-hydroxyprogesterone caproate or placebo, starting between 16 and 20 weeks of gestation and continuing until 36 weeks of gestation. The main outcome measure was adverse neonatal outcome. Secondary outcome measures were gestational age at delivery and delivery before 28, 32, and 37 weeks of gestation. RESULTS: We randomized 671 women. A composite measure of adverse neonatal outcome was present in 110 children (16%) born to mothers in the 17&agr;-hydroxyprogesterone caproate group, and in 80 children (12%) of mothers in the placebo group (relative risk [RR] 1.34; 95% confidence interval [CI] 0.95–1.89). The mean gestational age at delivery was 35.4 weeks for the 17&agr;-hydroxyprogesterone caproate group and 35.7 weeks for the placebo group (P=.32). Treatment with 17&agr;-hydroxyprogesterone caproate did not reduce the delivery rate before 28 weeks (6% in the 17&agr;-hydroxyprogesterone caproate group compared with 5% in the placebo group, RR 1.04; 95% CI 0.56–1.94), 32 weeks (14% compared with 10%, RR 1.37; 95% CI 0.91–2.05), or 37 weeks of gestation (55% compared with 50%, RR 1.11; 95% CI 0.97–1.28). CONCLUSION: 17&agr;-hydroxyprogesterone caproate does not prevent neonatal morbidity or preterm birth in multiple pregnancies.

This paper re-visits the problem of how we re-conceptualize human subjects within poststructuralist research. The turn to poststructuralist theory to inform research in the social sciences is complicated by the difficulty in thinking through what it means to put the subject under erasure. Drawing on a study in a Reggio Emilia inspired preschool in Sweden, and a study of neoliberalism's impact on academic work, this paper opens up thought about poststructuralism's subject . It argues that agency is the province of that subject .


This study aims to analyze the implementation of nationality education model  for youth across cultures through the SCORE-A model. The SCORE-A (Spatial Cultural Organization Religion and Economic Awareness) model relies on five aspects of consciousness as parameters of nationality education; spatial awareness ( S A); cultural awareness ( C A); organization awareness ( O A); religion awareness ( R A); economic awareness ( E A). The research employed a qualitative approach using document analysis, a literature review, interviews, and a questionnaire. The study was conducted in Jakarta over a six month period. The SCORE-A model was implemented  with twenty two respondents. Ninety one percent (91%) of the respondents rated the Score-A model or treatment during observation are very appropriate for improving the nationalism in loving their own country even though the youths come from different backgrounds of religion, ethic, and language. During applying the SCORE-A model, the respondents were developed critical and creative thinking skills. Although there are some limitations in applying the SCORE-A model such as participants differences, the results show participants' engagement in developing their nationality awareness. Therefore, it is suggested that the model can be implemented in other areas.


The advent of nanoelectronics originates (1) challenges in how to configure or "teach" self-assembled systems and (2) opportunities to integrate memory, digital and analog processing into extremely small systems for sensing and/or embedded computing. This paper describes initial ideas towards nanoelectronic adaptive systems that rely on ultra dense array-like structures to implement fault-tolerant intelligent sensor systems that integrate computing, sensing and memory.


This paper presents novel depth sensing and augmented reality technologies based on mobile 3D platforms. The mobile stereoscopic cameras are utilized to provide a "soft depth sensor" generating instant depth estimation of the physical world. The depth sensing algorithms are proposed to recover the 3D geometric structure captured in single or multiple stereoscopic images. Then, two augmented reality applications are developed to showcase the advantages of the depth sensing capability, namely visual measurement and a 3D AR shooter game. In particular, the AR technology allows occlusion between physical and virtual objects. Both visual and quantitative results are shown to illustrate the novelty and effectiveness of the proposed algorithms.


If you've been avoiding terms like OAI and metadata, fear no more Well-known tech guru Marshall Breeding demystifies the Open Archives Initiative and explains how its harvesting protocol lets users reap the information they need more easily.


Scandinavian and European states alike are faced with a growing elderly population. Health factors leading to sensory loss, dementia and increasing physical frailty can pose barriers to independent living for this population. Research initiatives and implementation projects have cropped up at many levels of government with similar goals of seeking ways of addressing the diverse needs of the elderly citizen segment. Often projects find it difficult to gain a holistic understanding and may not succeed in obtaining the benefits of the larger European research agenda. This paper develops a "roadmap" or clarification of the larger European research agenda. It is our aim that local initiatives may be better able to apply the lessons learned from other research and be made aware of the knowledge resources available through the international European research community at large.


Ultrasound (US) and microbubble (MB) gene delivery has attracted growing interest as a clinically applicable gene therapy (GT). Though preclinical studies have investigated the system in various tissues, there is limited research in targeting the placenta. This is a potential therapeutic strategy for preeclampsia (PE), which has an underlying genetic basis and ineffective management strategies. Differentially expressed placental microRNAs (miRNAs) in PE may represent suitable targets for GT. Microbubbles (SonoVue) and plasmid (pGL3 or pGL4.13) were administered systemically to CD1 mice, followed by exposure of the heart to US (H14, 1.8 M.I., 1cm focal depth, 2 minutes), using Siemens Acuson Sequoia-512 system and 15L8 probe. Luciferase assays were performed to evaluate gene transfection. Significantly differentially expressed placental miRNAs in PE patients were identified as candidates based on detection by three or more screening studies. Expression of candidate miRNAs was measured by qRT-PCR in PE rat model placentas. In trial 1, low levels of luciferase activity were detected in the heart of treatment mouse 1, 2 and 3. In trial 2, luciferase activity was evident in the atria of treatment mouse 2. In trial 3, higher luciferase activity was detected in the ventricles of the treatment mouse and activity was also detected in the atria. The literature review identified eight candidate miRNAs. MiR-223 (1.46-fold increase) and miR-181a (0.81-fold decrease) were significantly differentially expressed in PE rat model placentas. MiR-223 and -181a may represent targets for US and MB gene delivery. Future studies will apply the US and MB gene delivery protocol for translation to targeting the placenta in our PE rodent model.


A descriptor-based approach to study the methanol-to-DME reaction in zeotypes from first-principles is herein used to investigate the different reaction mechanism by means of a mean-field microkinetic model. In this theoretical study we focus on Bronsted acidic zeotype catalysts. We demonstrate that the difference of OH stretch frequency for the bare site and when CO is adsorbed on the site is a good descriptor for the acidic strength of the site. Different types of zeotypes are herein studied; CHA, BEA and MFI zeolite frameworks, where besides the conventional Al exchange we also consider B, Ga and Fe exchanged structures, along with SAPO-34, Mg-AlPO-34, Zn-AlPO-34, and Ti-AlPO-34. These span a wide range of strength of the acidic sites. The top panel in the figure to the right shows the free energy landscape for the two main reaction mechanisms for BEA and B-BEA (which have quite different acidity). The concerted mechanism, where two methanol molecules adsorb simultaneously to form DME and water, is shown in lighter colours, and the stepwise mechanism, where one methanol dissociates to a methyl group, producing water, after which a second methanol molecule is adsorbed to form hydrogenated DME, which then easily dehydrogenates, is shown in the darker shades. The bottom panel in the figure shows the calculated turn-over frequency (TOF) for the two mechanisms as a function of temperature. This shows that the concerted mechanism is dominating at lower temperatures while the stepwise dominates at higher temperatures for both systems.

The meaning of experimentally determined characteristic temperatures is
 analyzed in terms of Hruby glass forming criterion. Despite various analyzed
 modifications it reveals that the sensitivity of original criterion is
 unsurpassable. The applicability of Sestak-Berggren empirical equation for
 the description of crystallisation kinetics is comparable with the classical
 modelling based on Johnson-Mehl-Avrami equation. Their employment is
 certainly dependent to the purpose of evaluation showing their substitution
 ability and limits.


This article developed and evaluated the effects of an orientation program for parents regarding the frequency of comments during their children's futsal competitions. The ones participating were parents of three children from the sub-eleven category. The study was divided into phases. In the baseline, the comments were recorded during the games. In the intervention, parents were individually instructed using the Cheering Parent's Guide. The evaluation after the intervention was similar to the one got after the baseline. The comments were categorized and quantified into positive, negative and neutral. The results demonstrated that parents emitted more positive than negative comments during the matches. The most significant changes were the reinforcing and instructive comments. It was noticed that the score of the game interfered in the comment rate, in more competitive games, the rate of motivating comments and criticisms raised. Despite the parents agreed on the importance of the intervention, the results suggested that it was only effective to change some categories.


The best treatment therapy for gastrointestinal cancer patients is assessed by the improvement of health status and quality of life (QoL) after treatments. Malnutrition is related to loss of muscle strengths which leads to lower physical performance and emotional status. Thus, this study aimed to estimate the effects of nutritional interventions on the improvement of QoL among gastrointestinal patients undergoing chemotherapy in Vietnam.


As described elsewhere in this issue of BJHS, preliminary steps towards founding a society for the history of science in Britain were taken in 1946. A meeting was held at the Science Museum, London, on 22 November 1946, chaired by Herbert Dingle, at which Gavin de Beer formally proposed the foundation of a history of science society, seconded by Michael Roberts. A provisional committee was appointed to draw up rules and a constitution.


[Objective]To discuss the effects of DHS and compression screw application on femoral intertrochanteric fracture.[Method]Internal fixation was performed with DHS,DHS and compression screw,Ender nail and proximal femoral anatomical plate in 185 patients with femoral intertrochanteric fracture.The main outcome measures were operation duration,coxa adducta rates and postoperative Sanders scoring.[Result]All patients were followed up for 9-48 months.Operation duration was similar in the four groups.There were significant differences in coxa adducta rates and postoperative Sander's scores.According to the Sander's scores,the excellent to good rates in DHS and compression screw,DHS,Ender nail and proximal femoral anatomical plate groups were 94.6%,85.3%,75.4% and 80.6%,respectively.The coax adducta rates were 2.4%,9.5%,22.2% and 19.2%,respectively.[Conclusion]All the four kinds of internal fixation can be used for femoral intertrochanteric fracture,but DHS and compression screw is the best one for its good restoration of joint function and has no or little complication.


Preliminary communication Traditional and vernacular housing was developed in close relation between the functional needs of the occupants, the culture, climate, and other aspects of the living and built environment. Over the course of the last decades, most developing countries, including Libya, have experienced a rapid economic growth and increase in population, leading to the increase in construction of contemporary single family houses influenced by western models. The paper analyses aspects of thermal comfort in traditional single family houses in mountain (city of Gharyan) and desert regions (old city of Ghadames) in Libya with an aim to investigate advantages of the vernacular concepts in contemporary design. The study will establish valorisation criteria by researching structures, materials, internal arrangement, roof, openings and other aspects that influence sustainability. The results will be used in the fields of architecture, urban design and building industry in Libya, since the knowledge of traditional concepts and elements sustained through a long period of time will be valuable in building healthy homes and saving non-renewable energy in contemporary structures.


The basic objectives of this work included: making additional test samples of 1000 A (at 12 T) conductor, scaling up the production of 3500 A conductor to larger billets, and improving the performance of 1000 A size conductor by utilizing 13.5 wt% tin-bronze rather than 10% bronze. Additional samples of 1000 A conductor were made successfully from a 51 mm diameter third-stage billet.

This paper reviews options for creating an enabling environment for the construction industry, thus leading to more involvement of private contractors and consultants in improved management of road assets. The process, which is of particular importance for economies in transition, begins with separating the functions of planning and management from implementation of road works. Forms of contract reviewed include price based and cost based, procedural to functional specifications (or method based and performance based), and short and long term. These different forms have several implications on the risk allocation between client and contractor; the risks to the highway agency tend to decrease as the agency shifts from force account (or direct labor) to short and long-term forms of contract with the private sector, including concessions. Highway agencies have increased private sector involvement in an attempt to: reduce the amount of highway agency resources required on a highway project; reallocate performance risk; increase contractor innovation; increase the quality of constructed products; and reduce life cycle costs of highway projects. A summary of recent experience in the increased involvement of the private sector in highway asset management is summarized for countries such as Australia, New Zealand, the United State, the United Kingdom, and Argentina.


In the running state of equipment, the accurate discovery and diagnosis of existing problems is an effective means to ensure the quality and benefit of system operation. Therefore, by using deep learning and knowledge mapping in practical exploration, researchers of various countries have put forward an intelligent fault diagnosis method based on multi-modal information of equipment, which can not only discover the hidden problems within the system in time, but also put forward effective prevention countermeasures based on the diagnosis of problems. In this paper, after understanding the knowledge graph technology and deep learning concept, a corresponding system model was constructed by extracting and integrating the collected multi-modal data information and referring to doctors' diagnosis and treatment process of patients. The final experimental results show that the system can diagnose the equipment autonomously and effectively improve the efficiency of daily management of the system.


Our commentators come from many fields and disciplines and express highly divergent views, illustrating broad interest in the question. From the breadth of comments, we have identified two recurring themes, which we focus on here. The first is a preponderance of cautionary remarks about evaluating the differences between humans and nonhuman animals. The second concerns whether considering animals as worthy of moral consideration is one of many useful tools for conservationists trying to prevent extinction, habitat destruction, and climate change. Colin A. Chapman's research focuses on how the environment influences animal abundance and social organization. Given their plight, he has applied his research to conservation. He has conducted research in Kibale National Park in Uganda for 30 years, contributed to the park's development and protection, and has devoted great effort to promoting conservation by helping the rural communities.


Isomerization reaction of slash pine rosin in alcohol catalyzed by strong acid type cation exchange resin under different heat-conditions was studied.The results showed that the isomerization reaction of slash pine rosin catalyzed by strong acid type cation exchange resin with heat reflux method had mainly characteristic of acid catalysis and was greatly improved by the cooperation with microwave irradiation;when the isomerization equilibrium of abietic-type resin acids was reached after reacting for 2 h,abietic acid and isopimaric acid were the main resin acid and could be separated and purified by amine salt method after the catalyst was simply separated from reactants by filtration.
