AKTUALISASI SILA PERTAMA PANCASILA PADA PEMBELAJARAN DI SEKOLAH DASAR SEBAGAI PENINGKATAN KARAKTER RELIGIUS
Religious character is the most basic and main character that needs to be instilled in learners because religion becomes the basis in the life of the individual, society, and the State. The data collected by the author is a journal article with a range of 2018 to 2022. This data is determined by the systematic literature review method. The source of the literature review is obtained from search results on the Google Schoolar electronic database. In the first precept reads" Almighty Godhead" there are religious values including: a) Belief in the existence of an Almighty God with his all-perfect qualities, and b) Devotion to God Almighty, that is, to abide by all of his rules and obey all of his commands
Phase Transition in the Number Partitioning Problem
Number partitioning is an NP-complete problem of combinatorial optimization.
A statistical mechanics analysis reveals the existence of a phase transition
that separates the easy from the hard to solve instances and that reflects the
pseudo-polynomiality of number partitioning. The phase diagram and the value of
the typical ground state energy are calculated.Comment: minor changes (references, typos and discussion of results
Sequential Hybrid Beamforming Design for Multi-Link mmwave Communication
In this paper, we propose a sequential hybrid beamforming design for
multi-link transmission over mmwave frequency bands. As a starting point, a
baseline data communication link is established via traditional analog
beamforming at both the BS and UE. If an extra RF chain is available at the UE,
it can continue to probe the propagation environment at the same frequencies.
In case the environment is favorable and system resources allow, a secondary
data communication link is established to enable multi-stream transmission. In
principle, the secondary link could be served by the same BS and/or one or
several other BS(s). To initialize the secondary data communication link, a
parallel beam search scheme is proposed, which helps the UE/BS to find a
suitable beam pair with given optimization criteria without interrupting the
baseline data communication. By applying the proposed two-step approach, hybrid
beamforming becomes an add-on feature that can be easily switched on over an
analog beamforming enabled system without interrupting its operation whenever
system requires. Meanwhile, the information obtained by deploying the proposed
parallel beam search scheme can also be used for deciding a back-up beam pair
if signal blockage occurs to the baseline data communication link
On the ground states of the Bernasconi model
The ground states of the Bernasconi model are binary +1/-1 sequences of
length N with low autocorrelations. We introduce the notion of perfect
sequences, binary sequences with one-valued off-peak correlations of minimum
amount. If they exist, they are ground states. Using results from the
mathematical theory of cyclic difference sets, we specify all values of N for
which perfect sequences do exist and how to construct them. For other values of
N, we investigate almost perfect sequences, i.e. sequences with two-valued
off-peak correlations of minimum amount. Numerical and analytical results
support the conjecture that almost perfect sequences do exist for all values of
N, but that they are not always ground states. We present a construction for
low-energy configurations that works if N is the product of two odd primes.Comment: 12 pages, LaTeX2e; extended content, added references; submitted to

Common DNA sequence variation influences 3-dimensional conformation of the human genome.
BACKGROUND:The 3-dimensional (3D) conformation of chromatin inside the nucleus is integral to a variety of nuclear processes including transcriptional regulation, DNA replication, and DNA damage repair. Aberrations in 3D chromatin conformation have been implicated in developmental abnormalities and cancer. Despite the importance of 3D chromatin conformation to cellular function and human health, little is known about how 3D chromatin conformation varies in the human population, or whether DNA sequence variation between individuals influences 3D chromatin conformation. RESULTS:To address these questions, we perform Hi-C on lymphoblastoid cell lines from 20 individuals. We identify thousands of regions across the genome where 3D chromatin conformation varies between individuals and find that this variation is often accompanied by variation in gene expression, histone modifications, and transcription factor binding. Moreover, we find that DNA sequence variation influences several features of 3D chromatin conformation including loop strength, contact insulation, contact directionality, and density of local cis contacts. We map hundreds of quantitative trait loci associated with 3D chromatin features and find evidence that some of these same variants are associated at modest levels with other molecular phenotypes as well as complex disease risk. CONCLUSION:Our results demonstrate that common DNA sequence variants can influence 3D chromatin conformation, pointing to a more pervasive role for 3D chromatin conformation in human phenotypic variation than previously recognized
Jabba: hybrid error correction for long sequencing reads using maximal exact matches
Third generation sequencing platforms produce longer reads with higher error rates than second generation sequencing technologies. While the improved read length can provide useful information for downstream analysis, underlying algorithms are challenged by the high error rate. Error correction methods in which accurate short reads are used to correct noisy long reads appear to be attractive to generate high-quality long reads. Methods that align short reads to long reads do not optimally use the information contained in the second generation data, and suffer from large runtimes. Recently, a new hybrid error correcting method has been proposed, where the second generation data is first assembled into a de Bruijn graph, on which the long reads are then aligned. In this context we present Jabba, a hybrid method to correct long third generation reads by mapping them on a corrected de Bruijn graph that was constructed from second generation data. Unique to our method is that this mapping is constructed with a seed and extend methodology, using maximal exact matches as seeds. In addition to benchmark results, certain theoretical results concerning the possibilities and limitations of the use of maximal exact matches in the context of third generation reads are presented
