The Effective Field Theory of Large-Scale Structure in the presence of Massive Neutrinos

We develop a formalism to analytically describe the clustering of matter in the mildly non-linear regime in the presence of massive neutrinos. Neutrinos, whose free streaming wavenumber ($k_{\rm fs}$) is typically longer than the non-linear scale ($k_{\rm NL}$) are described by a Boltzmann equation coupled to the effective fluid-like equations that describe dark matter. We solve the equations expanding in the neutrino density fraction $(f_\nu)$ and in $k/ k_{\rm NL}$, and add suitable counterterms to renormalize the theory. This allows us to describe the contribution of short distances to long-distance observables. Equivalently, we construct an effective Boltzmann equation where we add additional terms whose coefficients renormalize the contribution from short-distance physics. We argue that neutrinos with $k_{\rm fs}\gtrsim k_{\rm NL}$ require an additional counterterm similar to the speed of sound ($c_s$) for dark matter. We compute the one-loop total-matter power spectrum, and find that it is roughly equal to $16f_\nu$ times the dark matter one for $k$'s larger that the typical $k_{\rm fs}$. It is about half of that for smaller $k$'s. The leading contribution results from the back-reaction of the neutrinos on the dynamics of the dark matter. The counterterms contribute in a hierarchical way: the leading ones can either be computed in terms of $c_s$, or can be accounted for by shifting $c_s$ by an amount proportional to $f_\nu$.
Study of E-Readiness: Integration of SDGS Indicators in Village Development Planning in Malo District, Bojonegoro Regency

The government has implemented various digital-based data applications for village development. Unfortunately, the use of this technology by village officials is still a challenge. Using the Strategy, Technology, Organization, People and Environment (STOPE) framework, this research is measuring the E-readiness of the village apparatus in using the Village SDGs data for development planning as well as to explore how the village apparatus is ready to synergize various digital-based applications in village development planning. The concept of E-readiness is the ability of the government and its citizens to take advantage of the potential of information and communication technology in governance process. This research uses the descriptive method. The research was conducted in seven villages in the Malo district, Bojonegoro regency. The results showed that the readiness of village government officials to manage data is promising. Some of the village government Readiness subdomains in the STOPE framework have achieved good results (ready and very ready). However, some sub-domains have not yet reached the ready category in integrating SDGs data in development planning and programs.
Meta-Analisis Risiko Hipertensi dengan Penyakit Stroke di Asia

Funnel Plot, Regresi Egger and Abstract One of the most deadly cardiovascular diseases is stroke. The 2017 Global Burden of Disease Study estimates that stroke is the second leading cause of death in 2016 and will remain in the same position in 2040. Hypertension as a risk factor for stroke is also estimated to increase, where it is estimated that the number of adults with hypertension will increase by 60% by 2025. This study uses a systematic review method and meta-analysis to look at the risk of hypertension with stroke in Asia. Further analysis by stroke subtype was also performed. Literature searches were performed on the PubMed, EBSCO and Google Scholar databases. The Q test was performed to determine the heterogeneity of the included studies. Funnel Plot, Egger Regression test and Trim and Fill methods were used to identify publication bias and by transforming the model between the Fixed Effect Model and the Random Effect Model for sensitivity analysis. The results of the meta-analysis of data showed that hypertension affected the incidence of stroke with Pooled OR 95% CI 5.9 (4.50-7.74). The funnel plot and also the results from Egger's test on the results of the meta-analysis of the risk of hypertension with stroke gave the results of a publication bias with the conclusion that 5 (five) articles were missing. This publication bias is assumed to occur due to lack of database, no manual search was conducted to find articles with insignificant results. In addition, relevant articles that are still in the form of 'grey literature' such as conference proceedings, dissertation, thesis and technical reports are not included in the analysis, some other relevant articles are inaccessible and often contain limited or incomplete data.
Spin excitations in La 2 CuO 4 : Consistent description by inclusion of ring exchange

We consider the square lattice Heisenberg antiferromagnet with plaquette ring exchange and a finite interlayer coupling leading to a consistent description of the spin-wave excitation spectrum in La 2 CuO 4 . The values of the in-plane exchange parameters, including ring exchange J@, are obtained consistently by an accurate fit to the experimentally observed in-plane spin-wave dispersion, while the out-of-plane exchange interaction is found from the temperature dependence of the sublattice magnetization at low temperatures. The fitted exchange interactions J= 151.9 meV and J@=0.24J give values for the spin stiffness and the Neel temperature in excellent agreement with the experimental data.
Investigation of the role of plasma channels as waveguides for laser-wakefield accelerators

The role of plasma channels as waveguides for laser-wakefield accelerators is discussed in terms of the results of experiments performed with the Astra-Gemini laser, numerical simulations using the code WAKE, and the theory of self-focusing and self-guiding of intense laser beams. It is found that at a given electron density, electron beams can be accelerated using lower laser powers in a waveguide structure than in a gas-jet or cell. The transition between relativistically self-guided and channel-assisted guiding is seen in the simulations and in the behaviour of the production of electron beams. We also show that by improving the quality of the driving laser beam the threshold laser energy required to produce electron beams can be reduced by a factor of almost 2. The use of an aperture allows the production of a quasi-monoenergetic electron beam of energy 520 MeV with an input laser power of only 30 TW.
Supersymmetric QCD: Renormalization and mixing of composite operators

We study $4$-dimensional SQCD with gauge group $SU(N_c)$ and $N_f$ flavors of chiral super-multiplets on the lattice. We perform extensive calculations of matrix elements and renormalization factors of composite operators in Perturbation Theory. In particular, we compute the renormalization factors of quark and squark bilinears, as well as their mixing at the quantum level with gluino and gluon bilinear operators. From these results we construct correctly renormalized composite operators, which are free of mixing effects and may be employed in non-perturbative studies of Supersymmetry. All our calculations have been performed with massive matter fields, in order to regulate the infrared singularities which are inherent in renormalizing squark bilinears. Furthermore, the quark and squark propagators are computed in momentum space with nonzero masses. This work is a feasibility study for lattice computations relevant to a number of observables, such as spectra and distribution functions of hadrons, but in the context of supersymmetric QCD, as a forerunner to lattice investigations of SUSY extensions of the Standard Model.
Graphene Thermal Interface Materials – State-of-the-Art and Application Prospects

We provide a summary of the fundamentals of thermal management, outline the state-of-the-art in the field of thermal interface materials, and describe recent developments in graphene-based non-curing and curing composites used for thermal management. The discovery of unique heat conduction properties of graphene and few-layer graphene motivated research activities worldwide focused on creating efficient graphene-based thermal interface materials. While the initial focus of these studies was on obtaining the maximum possible thermal conductivity of the composites, recently the attention has shifted to practical problems of minimizing the thermal contact resistance at interfaces, optimizing the size distribution of graphene as filler, and addressing the issues of scalability, stability, and production costs at commercial scales. We conclude the review with a general outlook for commercial applications of graphene in the thermal management of electronics.
High Accuracy and Low Complexity Lidar Place Recognition Using Unitary Invariant Frobenius Norm

Simultaneous localization and mapping (SLAM) is used in solving the problems of localization, navigation, and map construction for autonomous vehicles moving in unknown environments. Place recognition is an inevitable subject in SLAM, and the current lidar-based methods have been popularized for their rising environmental robustness. Currently, the place recognition method with lidar has attracted much attention due to its high environmental robustness. However, many 3-D laser point cloud methods for place recognition descriptors construction with the local or global point-cloud data omit some intrinsic properties of the point clouds. In this article, we propose a place recognition method based on the unitary invariance of the Frobenius norm for utilizing different attributes of ground points and non-ground points. Specifically, the interpretable filtering framework and a dynamic threshold adjustment strategy are raised according to different environments and sensors with intensity and geometric information. As commissioning, the comparative experiments are conducted with CHDloop datasets and public KITTI datasets of different scales and access types. Compared to the original scan context (SC) and intensity SC (ISC) methods, our proposed method achieves higher efficiency while maintaining an improved recall rate and precision. This novel method has been integrated into the existing lidar SLAM and formed a new framework FSC_ALOAM that reduces drifts in point-cloud mapping. The entire process improves the accordance of maps at the identical position in auto-driving.
Diversity of reef fish species in presence of mangrove habitat in Ternate, North Maluku, Indonesia

Abstract. Utama RS, Renyaan J, Nurdiansah D, Makatipu PC, Suyadi, Hapsari BW, Martha E, Rahayu EMD, Sugiharto A. Akbar N. 2022. Diversity of reef fish species in presence of mangrove habitat in Ternate, North Maluku, Indonesia. Biodiversitas 23: 5184-5193. Research on reef fish has been widely reported, where information about reef fish communities is an important factor for evaluating fisheries management and coral reef management. Mangroves as the nursery, foraging, and growing areas were also important to assure sustainable reef fish fisheries. This paper studies reef fish abundance and diversity in Ternate Waters in the presence of mangrove in coral reef habitats. To determines coral reef condition underwater photo transect was performed while an underwater visual census (UVC) was used to determine the abundance and diversity of reef fishes in Ternate waters between 2017 and 2018. A total of 14 stations were used, with eight stations near the mangroves and six stations that did not contain mangroves. Based on the observation, fish species richness in mangrove absence was higher than in the presence of mangroves, with 68 and 65 species in 2017 and 66 and 62 species in 2018. However, the abundance of reef fish was recorded high in the presence of mangroves than in the absence of mangroves, with 390 and 289 individual differences in 2017 and 2018. Mangroves' complexity affected part of reef fish communities in Ternate water, particularly Lutjanidae, Serranidae, and Scaridae, which might influence the abundance of reef fishes rather than the species richness. In addition, carnivore shows a negative effect in the presence of mangroves, in contrast with herbivores. It is related to mangrove functioning as a temporary shelter when high-pressure presence in their natural habitat (reef) and a place for foraging. Therefore, mangrove management must be a consideration in the coral reef or fisheries management program.
High-pressure compressibility and electronic properties of bismuth silicate 
Bi2SiO5
 from synchrotron experiments and first-principles calculations

The high pressure structural properties of bismuth oxide Bi2SiO5 have been investigated up to 28 GPa using in situ powder synchrotron X-ray diffraction and up to 50 GPa with DFT calculations. The monoclinic structure is found to persist up to about 20 GPa, where a notable change in the compressibility occurs. The DFT data imply that this is due to a second-order phase transition from the ambient condition monoclinic structure with space group Cc to an orthorhombic polymorph with space group Cmcm. This transition involves the straightening of the chains formed by corner-connected SiO4 tetrahedra, that suppresses the ferroelectricity in the high pressure, centrosymmetric phase of Bi2SiO5. The stereo-chemical activity of the Bi3+ lone electron pair is found to decrease with increasing pressure, but it can still be identifed in the calculated electron density difference maps at 50 GPa.
Universal approximations of discrete-time control systems over finite time

We present an algorithm for obtaining approximate internal descriptions for a discrete-time control system, given a finite number of external experiments (input-output data). The system is required only to be causal, with a continuous input-output map. The experiments should be done in a prescribed way, with bounded inputs acting over a finite period of time. The approximation will be valid over the ranges of inputs and time covered by the experiments. The algorithm can be considered as an exact partial realization procedure for state-affine systems. An e-stable computer program will be sketched.
Scalar geons in Born-Infeld gravity

The existence of static, spherically symmetric, self-gravitating scalar field solutions in the context of Born-Infeld gravity is explored. Upon a combination of analytical approximations and numerical methods, the equations for a free scalar field (without a potential term) are solved, verifying that the solutions recover the predictions of General Relativity far from the center but finding important new effects in the central regions. We find two classes of objects depending on the ratio between the Schwarzschild radius and a length scale associated to the Born-Infeld theory: massive solutions have a wormhole structure, with their throat at r≈ 2M, while for the lighter configurations the topology is Euclidean. The total energy density of these solutions exhibits a solitonic profile with a maximum peaked away from the center, and located at the throat whenever a wormhole exists. The geodesic structure and curvature invariants are analyzed for the various configurations considered.
Spin-based single-photon transistor, dynamic random access memory, diodes, and routers in semiconductors

The realization of quantum computers and quantum Internet requires not only quantum gates and quantum memories, but also transistors at single-photon levels to control the flow of information encoded on single photons. Single-photon transistor (SPT) is an optical transistor in the quantum limit, which uses a single photon to open or block a photonic channel. In sharp contrast to all previous SPT proposals which are based on single-photon nonlinearities, here I present a design for a high-gain and high-speed (up to THz) SPT based on a linear optical effect: giant circular birefringence induced by a single spin in a double-sided optical microcavity. A gate photon sets the spin state via projective measurement and controls the light propagation in the optical channel. This spin-cavity transistor can be directly configured as diodes, routers, DRAM units, switches, modulators, etc. Due to the duality as quantum gate and transistor, the spin-cavity unit provides a solid-state platform ideal for future Internet: a mixture of all-optical Internet with quantum Internet.

Abstract. Lukman, Dinarti D, Siregar UJ, Turjaman M, Sudarsono. 2022. Characterization and identification of agarwood-producing plants (Aquilaria spp.) from North Aceh, Indonesia, based on morphological and molecular markers. Biodiversitas 23: 4861-4871. Agarwood is one of the non-timber export commodities important as raw materials for bioindustry. There are 26 agarwood-producing plant species in Indonesia belonging to three families (Thymelaeaceae, Euphorbiaceae, and Fabaceae). This study aims to identify the agarwood-producing plant species in North Aceh District, Aceh Province, Indonesia, based on their morphological and molecular characters. The evaluated morphological characteristics include the bark and leaf structures of endemic plants. Molecular characterization was carried out by sequencing of matK, ITS, and trnL-trnF genes. The collected data were analyzed using the appropriate software, such as R software, BlastX, Geneious Prime and MEGA X. The evaluated 66 accessions were clustered into two major groups based on their morphology. Group 1 consisted of 10.61% of the evaluated accessions is identified as Aquilaria beccariana. Group 2 was further classified into two subclusters (Group 2a and 3b). Group 2a consisted of 10,61% of the accessions as A. malaccensis and Group 2b consisted of 78,79% of the accessions as A. microcarpa. All samples are identified as A. malaccensis based on the matK DNA sequences. Meanwhile, Groups 1 are identified as A. beccariana and Group 2a and 2b as A. microcarpa based on the ITS sequences. Based on the trnL-trnF sequences, Groups 1 and 2a was identified as A. malaccensis and Group 2b as A. microcarpa.
The Principle of Temporal Sequence in the Teaching of Chinese as a Second Language

This study investigates the capacity of elementary-level Chinese second language learners to memorize serial verb sentences based on the results of a questionnaire. Our findings show that adult second language learners employ the concept of temporal sequence in language learning, consciously or unconsciously, whether or not the chronological principle has been formally taught. Therefore, we propose that specific cognitive principles, such as the chronological principle, should be carefully applied or formally taught in language training to maximize teaching and learning effectiveness.
LOW-RESOLUTION NEAR-INFRARED STELLAR SPECTRA OBSERVED BY THE COSMIC INFRARED BACKGROUND EXPERIMENT (CIBER)

We present near-infrared (0.8–1.8 μm) spectra of 105 bright ( < 10) stars observed with the low-resolution spectrometer on the rocket-borne Cosmic Infrared Background Experiment. As our observations are performed above the Earth's atmosphere, our spectra are free from telluric contamination, which makes them a unique resource for near-infrared spectral calibration. Two-Micron All-Sky Survey photometry information is used to identify cross-matched stars after reduction and extraction of the spectra. We identify the spectral types of the observed stars by comparing them with spectral templates from the Infrared Telescope Facility library. All the observed spectra are consistent with late F to M stellar spectral types, and we identify various infrared absorption lines.
Calculation of the optical response of atomic clusters using time-dependent density functional theory and local orbitals

We report on a general method for the calculation of the frequency-dependent optical response of clusters based upon time-dependent density functional theory (TDDFT). The implementation is done using explicit propagation in the time domain and a self-consistent program that uses a linear combination of atomic orbitals (LCAO). Our actual calculations employ the SIESTA program, which is designed to be fast and accurate for large clusters. We use the adiabatic local density approximation to account for exchange and correlation effects. Results are presented for the imaginary part of the linear polarizability, $\mathrm{Im}\ensuremath{\alpha}(\ensuremath{\omega}),$ and the dipole strength function, $S(\ensuremath{\omega}),$ of ${\mathrm{C}}_{60}$ and ${\mathrm{Na}}_{8},$ and compared to previous calculations and to experiment. We also develop a method for the calculation of the integrated frequency-dependent second-order nonlinear polarizability for the case of a step function electric field, ${\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\gamma}}}_{\mathrm{step}}(\ensuremath{\omega}),$ and present results for ${\mathrm{C}}_{60}. $
Stress-controlled Pb(Zr0.52Ti0.48)O3 thick films by thermal expansion mismatch between substrate and Pb(Zr0.52Ti0.48)O3 film

Polycrystalline Pb(Zr0.52Ti0.48)O3 (PZT) thick films (thickness ∼10 μm) were successfully fabricated by using a novel aerosol deposition technique on Si wafer, sapphire, and single crystal yitria stabilized zirconia (YSZ) wafer substrates with Pt electrodes and their dielectric, ferroelectric, and piezoelectric properties, and in-plane stresses were investigated. The films with different stress conditions were simply controlled by the coefficient of thermal expansion (CTE) misfit of PZT films and substrates. The results showed that the films bearing in-plane compressive stress deposited on the YSZ and sapphire substrates have superior dielectric, ferroelectric (∼90%), and piezoelectric (>200%) properties over that of the Si wafer. Among these three substrates, YSZ shows superior properties of the PZT films. However, films on Si wafer with tensile stress present lower properties. We believed that in-plane compressive stresses within the films are benefited, the formation of c-domain parallel to the thickne.
The effect of capital adequacy ratio and loan to deposit ratio on return on asset with non-performing loan as moderating variable in banking companies listed in BEI

This study aims to know the impact of capital adequacy and loan to deposit ratio on financial performance with credit risk as a moderating variable in the banking companies listed on the Indonesia Stock Exchange period of 2015 to 2019.We have 43 banking companies in population, and we take 23 companies as our samples. The data analysis model is an interaction method, usually referred to as Moderated Regression Analysis (MRA). The results show that capital adequacy has an impact on financial performance in banking companies listed on the Indonesia Stock Exchange from 2015 to 2019. The loan to deposit ratio does not effect financial performance. The existence of credit risk, as the moderating variable, will strengthen the relationship between capital adequacy and financial performance and the relationship between the loan to deposit ratio and financial performance. Also, the existence of credit risk as the moderating variable will strengthen capital adequacy and loan to deposit ratio on financial performance.
