Makna Ragi dalam Ajaran Tuhan Yesus Tentang Kewaspadaan
Ajaran Tuhan Yesus ada yang berbentuk kalimat lugas dan ada yang kiasan. Penggunaan kata “ragi” dalam beberapa kalimat yang disampaikan Tuhan Yesus tentang kewaspadaan adalah dalam makna kiasan. Itu sebabnya perlu dicari makna kata tersebut sesuai prinsip-prinsip eksegesis.Metode eksegesis yang digunakan meliputi penetapan teks Alkitab yang akan dieksegesis, yaitu Matius 16:6, analisis struktur kalimat dan menyusun terjemahan, analisis konteks penggunaan ragi pada masa itu, penggalian pokok-pokok teologis berdasarkan arti kata dan susunan kata dalam kalimat, dan penerapan eksegesis kepada konteks masa kini.Kesimpulan dari penelitian ini adalah, Yesus menggunakan istilah ragi karena ragi adalah sesuatu yang umum digunakan dalam masyarakat, sehingga arti simboliknya dengan mudah ditarik berdasarkan apa yang dipahami oleh masyarakat. Ragi menggambarkan ajaran, dan ada kesamaan karakteristik ragi dan karakteristik ajaran; pembusukan yang disebabkan oleh sejumlah kecil ragi tidak nampak prosesnya namun nyata Perubahannya, demikian pula cukup sedikit ajaran yang tidak sehat yang dibiarkan mengkontaminasi memiliki potensi untuk merusak seluruh karakter seseorang. Ajaran yang harus diwaspadai adalah pengutamaan terhadap hal-hal yang lahiriah lebih daripada yang rohani, termasuk di dalamnya keangkuhan, kemunafikan, dan pandangan duniawi
The dynamics of loop formation in a semiflexible polymer
The dynamics of loop formation by linear polymer chains has been a topic of
several theoretical/experimental studies. Formation of loops and their opening
are key processes in many important biological processes. Loop formation in
flexible chains has been extensively studied by many groups. However, in the
more realistic case of semiflexible polymers, not much results are available.
In a recent study (K. P. Santo and K. L. Sebastian, Phys. Rev. E, \textbf{73},
031293 (2006)), we investigated opening dynamics of semiflexible loops in the
short chain limit and presented results for opening rates as a function of the
length of the chain. We presented an approximate model for a semiflexible
polymer in the rod limit, based on a semiclassical expansion of the bending
energy of the chain. The model provided an easy way to describe the dynamics.
In this paper, using this model, we investigate the reverse process, i.e., the
loop formation dynamics of a semiflexible polymer chain by describing the
process as a diffusion-controlled reaction. We perform a detailed
multidimensional analysis of the problem and calculate closing times for a
semiflexible chain which leads to results that are physically expected. Such a
multidimensional analysis leading to these results does not seem to exist in
the literature so far.Comment: 37 pages 4 figure
Speckle noise reduction in medical ultrasound RF raw images
Ultrasonography is the commonly used imaging modality for the examination of several pathologies due to its non-invasiveness, affordability and easiness of use. However, ultrasound images are degraded by an intrinsic artifact called 'speckle', which is the result of the constructive and destructive coherent summation of ultrasound echoes. This paper aims to generate B-mode images out of radiofrequency (RF) data following standard procedures, a series of steps such as envelope detection, log-compression and scan conversion. The best set of parameters of this pipeline will be selected in order to achieve B-mode images with high quality.info:eu-repo/semantics/publishedVersio
Diffusion of scientific credits and the ranking of scientists
Recently, the abundance of digital data enabled the implementation of graph
based ranking algorithms that provide system level analysis for ranking
publications and authors. Here we take advantage of the entire Physical Review
publication archive (1893-2006) to construct authors' networks where weighted
edges, as measured from opportunely normalized citation counts, define a proxy
for the mechanism of scientific credit transfer. On this network we define a
ranking method based on a diffusion algorithm that mimics the spreading of
scientific credits on the network. We compare the results obtained with our
algorithm with those obtained by local measures such as the citation count and
provide a statistical analysis of the assignment of major career awards in the
area of Physics. A web site where the algorithm is made available to perform
customized rank analysis can be found at the address

the rankings of scientists is at http://www.physauthorsrank.or
How the mere desire for certainty can lead to a preference for men in authority (particularly among political liberals)
Women are harmed by stereotypes about their fit for positions of authority and changing these stereotypes is not a simple task. As stereotypes have strong epistemic properties, individuals with a high need for cognitive closure (NCC; i.e., the desire for epistemic certainty) can be more likely to accept these stereotypes and, consequently, to prefer men in positions of authority. Consistent with the reactive liberal hypothesis, this effect could be actually more visible among individuals with both a high NCC and left-wing political orientations. We supported these hypotheses in a series of three studies. In Study 1 (N = 217), we found that manipulated NCC predicted preference for men in authority through stereotypes of women as not being fit for authority in a measurement-of-mediation design. In Study 2 (N = 151), we supported this effect in a mediation-as-process design. In Study 3 (N = 391), we found the indirect NCC effect on preference for men in authority was more visible among political liberals. A major implication of this work is that ways of changing the effect of these stereotypes should take into account the NCC, but particularly among individuals with left-wing beliefs
Percolation Effects in Very High Energy Cosmic Rays
Most QCD models of high energy collisions predict that the inelasticity
is an increasing function of the energy. We argue that, due to percolation of
strings, this behaviour will change and, at GeV, the
inelasticity will start to decrease with the energy. This has straightforward
consequences in high energy cosmic ray physics: 1) the relative depth of the
shower maximum grows faster with energy above the knee; 2) the energy
measurements of ground array experiments at GZK energies could be
overestimated.Comment: Correction of equation (19) and figures 3 and 4. 4 pages, 4 figure
