Improved quantum attack on several generalized unbalanced Feistel structures

By studying the attack technology based on Simon, Grover and other quantum algorithms for the security of block cipher structure, this paper proposes new quantum attack on 6 generalized unbalanced Feistel structures. We improve the attack results of n-cell structure, New Structure I/III/IV structure and FBC-like structure, and give a quantum attack on Skipjack structure for the first time. Based on Simon algorithm, this paper constructs a n2-round, a 12/12/6-round and a 4-round quantum distinguisher about n-cell structure, New structure I/III/IV and FBC-like structure, improving n2-n-1 rounds, 6 rounds/3 rounds/1 round and 1 round separately, comparing to the previous results. In addition, this paper also constructs a 9-round quantum distinguisher about Skipjack structure. Moreover, this paper proposes a quantum key recovery attack on the above six structures in combination with Grover algorithm, and the time complexities of attacks are analyzed.
Generating Tokenizers with Flat Automata

We introduce flat automata for automatic generation of tokenizers. Flat automata are a simple representation of standard finite automata. Using the flat representation, automata can be easily constructed, combined and printed. Due to the use of border functions, flat automata are more compact than standard automata in the case where intervals of characters are attached to transitions, and the standard algorithms on automata are simpler. We give the standard algorithms for tokenizer construction with automata, namely construction using regular operations, determinization, and minimization. We prove their correctness. The algorithms work with intervals of characters, but are not more complicated than their counterparts on single characters. It is easy to generate C++ code from the final deterministic automaton. All procedures have been implemented in C++ and are publicly available. The implementation has been used in applications and in teaching.
The Development of Early Warning System for College English Academic Performance Based by Big Data Computation

With the rise and development of big data technology, data mining has been applied to various education fields. Particularly, the use of data mining to predict students' academic performance has been explored by educators to optimize teaching decisions. By contrast, there still lacks a set of cohesive frameworks on how to use this big data technology in college English teaching, and how to incorporate data mining into a warning system needs to be further elucidated. In this context, we first analyzed the necessity of early warning for the college English academic performance, and then expatiated the development paths and implementation frameworks based on big data. We studied the technical framework of early warning for the college English academic performance to help teachers find problems and improve English teaching effects.
Unsupervised Feature Selection via Metric Fusion and Novel Low-Rank Approximation

Unsupervised feature selection aims to derive a compact set of features with desired generalization ability via removing the irrelevant and redundant features, yet challenging due to the unavailability of labels. Works about unsupervised feature selection always need to construct the similarity matrix, which makes the selected features highly depend on the accuracy of similarity measurement. However, existing works usually leverage a single fixed metric to build similarity matrix, which cannot fit various feature types very well and even damage the local manifold structure. To address this problem, we propose an adaptive multi-metric fusion by automatically integrating similarity across different metrics according to the specific data. Besides, to capture the global structure more precisely, a novel low-rank approximation method is proposed, which is relatively insensitive to the rank-norm parameter. Via the proposed novel low-rank approximation method, better tradeoff between the performance and robustness can be provided. Experimental results show that the accuracy performance of the proposed method can be boosted by $2\%-11\%$ , compared with previous methods.
Supersymmetric Partition Functions in the AdS/CFT Conjecture

We study supersymmetric partition functions in several versions of the AdS/CFT correspondence. We present an Index for superconformal field theories in d = 3, 4, 5, 6. This captures all information about the spectrum that is protected, under continuous deformations of the theory, purely by group theory. We compute our Index in N = 4 SYM at weak coupling using gauge theory and at strong coupling using supergravity and find perfect agreement at large N . We also compute this Index for supergravity on AdS4 × S and AdS7 × S and for the recently constructed Chern Simons matter theories. We count 1/16 BPS states in the free gauge theory and find qualitative agreement with the entropy of big black holes in AdS5. We note that the near horizon geometry of some small supersymmetric black holes is an extremal BTZ black holes fibered on a compact base and propose a possible explanation for this, based on giant gravitons. We also find the partition function of the chiral ring of the N = 4 SYM theory at finite coupling and finite N . Turning to AdS3, we study the low energy 1/4 and 1/2 BPS partition functions by finding all classical supersymmetric probe brane solutions of string theory on this
Approximation of convex bodies by axially symmetric bodies

We present an analog of the well-known theorem of F. John about the ellipsoid of maximal volume contained in a convex body. Let C be a convex body and let D be a centrally symmetric convex body in the Euclidean d-space. We prove that if D′ is an affine image of D of maximal possible volume contained in C, then C a subset of the homothetic copy of D′ with the ratio 2d-1 and the homothety center in the center of D′. The ratio 2d-1 cannot be lessened as a simple example shows.
Impact of Outborn/Inborn Birth Status of Infants Born at <29 Weeks of Gestation on Neurodevelopmental Impairment: A Nationwide Cohort Study in Korea

This study designed to evaluate the short- and long-term outcomes of outborn and inborn preterm infants enhancing the regional perinatal system in South Korea. It is a prospective cohort study of the Korean neonatal network database for infants born at <29 weeks of gestation between 2013 and 2015. Of 2995 eligible infants, 312 were outborn, and 976 completed the assessment of long-term outcome at 18–24 months of corrected age. The mean gestational age was significantly younger in outborn infants than in inborn infants (p = 0.004). The mean Apgar score at 5 min was higher in inborn infants (p = 0.046). More inborn preterm infants died before discharge (p < 0.001); however, most of the other short-term outcomes occurred significantly more often in outborn infants than in inborn infants. The outborn infants had higher odds of neurodevelopmental impairment (adjusted odds ratio (aOR) 2.412, 95% confidence interval (CI) 1.585–3.670), cerebral palsy (aOR 4.460, 95% CI 2.249–8.845) and developmental impairment (aOR 2.238, 95% CI 1.469–3.408). In preterm infants, the location of birth may be a key factor influencing short- and long-term outcomes. Thus, to provide adequate care and efficiently allocate medical resources to high-risk preterm infants, nationwide regional perinatal systems need to be improved and standardized.
Synthesis, characterization, and some pharmacological evaluation of 5-Thiocyanatouracil compound

5-Thiocyanotouracil (5-TCU) was prepared in convenient method involved direct reaction of Potassium thiocyanate with 5-Iodouracil in refluxing aqueous solvent to give white crystalline in very good yield and high purity. This compound is important because it is similar in structure to 5-Flourouracil, which is of great importance as anti-cancer drug that is still used today. FT-IR, 1H- NMR, 13C- NMR, and CHN elemental analyses were used to describe the product. Median lethal dose LD50, in vitro antiradical activity and antibacterial effects were done. The results indicated that 5-TCU has relatively high LD50, non-significate antioxidant effect compare with ascorbic acid, and some antibacterial activity.
Improved Ant Lion Algorithm for Solution of Optimal Power Flow

Improved Ant Lion Optimization (IALO) is a proposed swarm-based algorithm based on the antlion's distinctive hunting behavior, that mimics the swarming behavior of the antlion. The proposed IALO technique is developed by modifying the standard antlion optimization algorithm (ALO) by using levy fight distribution. The operating cost for thermal units is an important aspect in power flow system problems. In this study standard IEEE-30 bus test system has been taken into consideration to validate the effectiveness of proposed technique. IALO shown an improvement in operating cost, active power loss, voltage profile as well as in the execution time in comparison to conventional algorithms which is novelty of this paper. Therefore, the proposed IALO approach is a viable optimization tool for solving OPF power system optimization problems.
Determination of Apoptotic Mechanism of Action of Tetrabromobisphenol A and Tetrabromobisphenol S in Human Peripheral Blood Mononuclear Cells: A Comparative Study

Background: Tetrabromobisphenol A (TBBPA) is the most commonly used brominated flame retardant (BFR) in the industry. TBBPA has been determined in environmental samples, food, tap water, dust as well as outdoor and indoor air and in the human body. Studies have also shown the toxic potential of this substance. In search of a better and less toxic BFR, tetrabromobisphenol S (TBBPS) has been developed in order to replace TBBPA in the industry. There is a lack of data on the toxic effects of TBBPS, while no study has explored apoptotic mechanism of action of TBBPA and TBBPS in human leukocytes. Methods: The cells were separated from leucocyte-platelet buffy coat and were incubated with studied compounds in concentrations ranging from 0.01 to 50 µg/mL for 24 h. In order to explore the apoptotic mechanism of action of tested BFRs, phosphatidylserine externalization at cellular membrane (the number of apoptotic cells), cytosolic calcium ion and transmembrane mitochondrial potential levels, caspase-8, -9 and -3 activation, as well as PARP-1 cleavage, DNA fragmentation and chromatin condensation in PBMCs were determined. Results: TBBPA and TBBPS triggered apoptosis in human PBMCs as they changed all tested parameters in the incubated cells. It was also observed that the mitochondrial pathway was mainly involved in the apoptotic action of studied compounds. Conclusions: It was found that TBBPS, and more strongly TBBPA, triggered apoptosis in human PBMCs. Generally, the mitochondrial pathway was involved in the apoptotic action of tested compounds; nevertheless, TBBPS more strongly than TBBPA caused intrinsic pathway activation.

Gegenbauer-Chebyshev Integrals and Radon Transforms

We suggest new modifications of Helgason's support theorems and descriptions of the kernels for several projectively equivalent transforms of integral geometry. The paper deals with the hyperplane Radon transform and its dual, the totally geodesic transforms on the sphere and the hyperbolic space, the spherical slice transform, and the spherical mean transform for spheres through the origin. The assumptions for functions are formulated in integral terms. The proofs rely on the properties of the Gegenbauer-Chebyshev integrals which generalize Abel type fractional integrals on the positive half-line.

Analysis of Calcium Sulfate Scaling Phenomena on Reverse Osmosis Membranes by Scaling-Based Flux Model

In this study, the behavior of permeate flux decline due to scale precipitation of calcium sulfate on reverse osmosis membranes was investigated. The proposed scaling-based flux model is able to explain that permeate fluxes attributed to three mechanisms of scale precipitation—cake formation, surface blockage, and mixed crystallization—converge to the same newly defined scaling-based critical flux. In addition, a scaling index is defined, which determines whether scale precipitates on the membrane. The experimental results were analyzed based on this index. The mass-transfer coefficients of flat membrane cells used in the experiments were measured and, although the coefficients differed, they could be summarized in the same form as the Leveque equation. Considering the results of the scale precipitation experiments, where the operating conditions of pressure, solute concentration, temperature, and Reynolds number were varied, the convergent values of the permeate fluxes are explained by the scaling-based critical fluxes and the scale precipitation zones by the scaling indexes.

Thermal, Physical, and Optical Properties of the Solution and Melt Synthesized Single Crystal CsPbBr3 Halide Perovskite

Inorganic lead-halide perovskite, cesium lead bromide (CsPbBr3), shows outstanding optoelectronic properties. Both solution- and melt-based methods have been proposed for CsPbBr3 crystal growth. The solution-based growth was done at low-temperature, whereas the melt-based growth was done at high-temperature. However, the comparison of optical, physical, and defect states using these two different growth conditions has been scarcely studied. Here, we have compared the thermal and optical properties of solution-grown and melt-grown single crystals of CsPbBr3. Positron Annihilation Lifetime Spectroscopy (PALS) analysis showed that melt-grown crystal has a relatively smaller number of defects than the chemical synthesis method. In addition, crystals grown using the chemical method showed a higher fluorescence lifetime than melt-grown CsPbBr3.
EMIR, the near-infrared camera and multi-object spectrograph for the GTC. EMIR at GTC

We present EMIR, a powerful near-infrared (NIR) camera and multi-object spectrograph (MOS) installed at the Nasmyth focus of the 10.4 m GTC. EMIR was commissioned in mid-2016 and is offered as a common-user instrument. It provides spectral coverage of 0.9 to 2.5 $\mu m$ over a field of view (FOV) of 6.67x6. 67 squared arcmin in imaging mode, and 6.67x4 squared arcmin in spectroscopy. EMIR delivers up to 53 spectra of different objects thanks to a robotic configurable cold slit mask system that is located inside the cryogenic chamber, allowing rapid reconfiguration of the observing mask. The imaging mode is attained by moving all bars outside the FOV and then leaving an empty space in the GTC focal surface. The dispersing suite holds three large pseudo-grisms, formed by the combination of high-efficiency FuSi ion-etched ruled transmission grating sandwiched between two identical ZnSe prisms, plus one standard replicated grism. These dispersing units offer the spectral recording of an atmospheric window $J,H,K$ in a single shot with resolving powers of 5000, 4250, 4000, respectively for a nominal slit width of 0.6\arcsec, plus the combined bands $YJ$ or $HK$, also in a single shot, with resolution of $\sim$ 1000. The original Hawaii2 FPA detector, which is prone to instabilities that add noise to the signal, is being replaced by a new Hawaii2RG detector array, and is currently being tested at the IAC. This paper presents the most salient features of the instrument, with emphasis on its observing capabilities and the functionality of the configurable slit unit. Sample early science data is also shown.
High Prevalence of Anemia and Poor Compliance with Preventive Strategies among Pregnant Women in Mwanza City, Northwest Tanzania: A Hospital-Based Cross-Sectional Study

Anemia in pregnancy is prevalent in Tanzania despite the implementation of existing prevention strategies. This study aims to determine the level of compliance with anemia preventive strategies among pregnant women and the factors associated with poor compliance. A cross sectional study was conducted among 768 pregnant women who attended the Bugando Medical Center, Sekou-Toure Regional Hospital, Nyamagana District Hospital, and Buzuruga Health Center in Mwanza, Northwest Tanzania. The prevalence of anemia at term was 68.8% (95% CI, 65.5–72.0%). The average hemoglobin level at term was 10.0 g/dL (95% CI, 9.8–10.1). Only 10.9% of pregnant women complied fully with anemia-preventive strategies. A decrease in mean hemoglobin level was observed across levels of compliance, with women who were non-compliant displaying a significantly lower mean hemoglobin level (8.3 g/dL) compared to women who were fully compliant (11.0 g/dL). Poor compliance was associated with no formal or primary education and initiating antenatal care in the 2nd or 3rd trimester. Anemia in pregnancy was commonly associated with lack of compliance with preventive strategies among participants. There is a need for community-based health education on the importance of complying with anemia-preventive strategies in order to reduce the burden during pregnancy and the consequences of anemia to the unborn baby.
NPPT Bound Entanglement Exists

Every dXd bipartite system is shown to have a large family of undistillable states with nonpositive partial transpose (NPPT). This family subsumes the family of conjectured NPPT bound entangled Werner states. In particular, all one-copy undistillable NPPT Werner states are shown to be bound entangled.
Chloride Ions, Vascular Function and Hypertension

Blood pressure is determined by cardiac output and systemic vascular resistance, and mediators that induce vasoconstriction will increase systemic vascular resistance and thus elevate blood pressure. While peripheral vascular resistance reflects a complex interaction of multiple factors, vascular ion channels and transporters play important roles in the regulation of vascular tone by modulating the membrane potential of vascular cells. In vascular smooth muscle cells, chloride ions (Cl−) are a type of anions accumulated by anion exchangers and the anion–proton cotransporter system, and efflux of Cl− through Cl− channels depolarizes the membrane and thereby triggers vasoconstriction. Among these Cl− regulatory pathways, emerging evidence suggests that upregulation of the Ca2+-activated Cl− channel TMEM16A in the vasculature contributes to the increased vascular contractility and elevated blood pressure in hypertension. A robust accumulation of intracellular Cl− in vascular smooth muscle cells through the increased activity of Na+–K+–2Cl− cotransporter 1 (NKCC1) during hypertension has also been reported. Thus, the enhanced activity of both TMEM16A and NKCC1 could act additively and sequentially to increase vascular contractility and hence blood pressure in hypertension. In this review, we discuss recent findings regarding the role of Cl− in the regulation of vascular tone and arterial blood pressure and its association with hypertension, with a particular focus on TMEM16A and NKCC1.
Energy Harvesting For IoT Applications

Irrefutably, most of the IoT devices are energized through batteries. Owing to the restricted operating life of batteries, this is the need of hour to have IoT device which can get the power from device itself or there should be some alternative energy source which can continuously feed power to the IoT devices. As an alternative source, various energy harvesters are being used to power up the ample of IoT devices. Energy harvesters utilize some renewable resource of energy to produce the desired amount of DC output voltage to further feed to IoT devices. Therefore, the significance of energy harvesters for IoT applications is presented in this article. Starting with the demand of energy harvesters and their design, this article also presents the comparison and requirements of various energy harvesting systems for applications in IoT devices.
Design of Energy Efficient Magnitude Comparator Architecture using 8T XOR Gate

This paper proposes a CMOS comparator circuitry with a three-stage topology for a high-speed Analog-to-Digital Converter (ADC). The speed of ADC is limited by the used comparator. Hence, the optimization of the comparator is crucial for a fast ADC. In computationally intensive designs, the use of comparators is inevitable. The optimization of comparator design while maximizing speed, minimizing power dissipation, and minimizing area is needed. Though the dynamic logic-based comparators are successful in minimizing power consumption, they pose challenges such as low-speed and poor-noise margin. In this paper, a low power and area efficient magnitude comparator is designed by utilizing an 8T xor gate. In the proposed xor gate power gating is applied so that the power consumption can be optimized. This proposed low power xor –xnor module is the fundamental circuit in the comparator circuit. Hence, the power consumption of digital comparator is also reduced. The recommended comparator is composed of 2 modules namely, CEM (Comparison Evaluation Module) and the FM (Final Evaluation Module). All the designs are simulated in Tanner EDA tool using 180nm technology.
Effects of Rearing Management Applied throughout the Charolais Young Bulls’ Life on Carcass and Meat Quality

The aim of this work was to study, for the first time, the effects of the rearing management (from birth to slaughter) applied throughout the life of young bulls on carcass and meat quality. Five rearing managements were defined statistically, from a combination of 30 rearing factors, using a hierarchical clustering on principal components. This study considered the individual data of 179 Charolais young bulls from commercial farms. The carcass traits were more sensitive to rearing management than the meat traits. Rearing management had an effect mainly on fat and overall meat grain for the carcass, and on color and tenderness for the longissimus meat. However, it was possible to produce carcass and/or meat with similar properties from different rearing managements. Among the five rearing managements defined in this study, two were identified as allowing the best trade-off to produce simultaneously high carcass and meat quality. The first management was characterized by absence of growth period and a short fattening duration, with a wrapped haylage or corn silage-based diet. The second management was characterized by short pre-weaning and growth periods, and a long fattening period.
