description: The demagnetization factors for randomly packed spherical particle powders with different porosities, sample aspect ratios and monodisperse, normal and log-normal particle size distributions have been calculated using a numerical model. For a relative permeability of 2, comparable to room temperature Gd, the calculated demagnetization factor is close to the theoretical value. The normalized standard deviation of the magnetization in the powder was 6.0%-6.7%. The demagnetization factor decreased significantly, while the standard deviation of the magnetization increased, for increasing relative permeability.

description: Efforts to address the issue of carbon emissions of oil palm plantations have become a major topic of discussion. As a result, ideas to apply artificial compaction on peat with the aim of lowering CO2 have been introduced. However, information on the artificial compaction effect to carbon emission of tropical peat is limited. This study is the first to experimentally investigate the in-situ artificial compaction on two ecosystems: a secondary peat swamp forest (SF) and an oil palm plantation (OP). Treatment was based on peat depth vertical compression using a fabricated hybrid compaction apparatus, which also served as a static closed-chamber for gas entrapment purposes. The mixed gas was analysed using a portable automated gas analyser for gas sampling purposes. Peat samples were collected at the end of the experiment to determine their physicochemical properties. Water table level (WTL) was also monitored. The results reveal that the physicochemical properties of peat in both ecosystems were not affected by artificial compaction due to their interaction with WTL fluctuation. Nevertheless, CO2 and CH4 emission changes were observed in SF, and showed inverse patterns of reduction and enhancement at a percentage ratio of 1:2 (CO2:CH4) based on the different treatments, suggesting that peat depth decreases as a result of compression and thus becomes closer to the WTL. Although the significantly peat decomposition proxies influenced less than 28% of carbon emissions, WTL was also a key factor that caused CO2 and CH4 to exhibit inversely emissions by 61% and 70% from total variation, respectively. However, this was only observed for SF, owing to substrate availability in the former. Most importantly, this study suggests that artificial compaction should be carefully defined, as compaction effectiveness will decline due to WTL fluctuation. Consideration of the confounding factor between decomposition degree and WTL fluctuation is important to further understand the effect of artificial compaction on tropical peat.

description: The severe crowding towards the Galactic plane suggests that the census of nearby stars in that direction may be incomplete. Recently, Scholz reported a new M9 object at an estimated distance d~7 pc (WISE J072003.20-084651.2; hereafter WISE0720) at Galactic latitude b=2.3 degr. Our goals are to determine the physical characteristics of WISE0720, its kinematic properties, and to address the question if it is a binary object, as suggested in the discovery paper. Optical and infrared spectroscopy from the Southern African Large Telescope and Magellan, respectively, and spectral energy distribution fitting were used to determine the spectral type of WISE0720. The measured radial velocity, proper motion and parallax yielded its Galactic velocities. We also investigated if WISE0720 may show X-ray activity based on archival data. Our spectra are consistent with spectral type L0+/-1. We find no evidence for binarity, apart for a minor 2-sigma level difference in the radial velocities taken at two different epochs. The spatial velocity of WISE0720 does not connect it to any known moving group, instead it places the object with high probability in the old thin disk or in the thick disk. The spectral energy distribution fit hints at excess in the 12 and 22 micron WISE bands which may be due to a redder companion, but the same excess is visible in other late type objects, and it more likely implies a shortcoming of the models (e.g., issues with the effective wavelengths of the filters for these extremely cool objects, etc.) rather than a disk or redder companion. The optical spectrum shows some Halpha emission, indicative of stellar activity. Archival X-ray observations yield no detection.

description: This is number four of 42 preservation briefs prepared by the Technical Preservation Services of the National Park Service. This brief focuses on roofing for historic buildings. The essential ingredients for replacing and maintaining a historic roof are: understanding the historic character of the building and being sympathetic to it, careful examination and recording of the existing roof and any evidence of earlier roofs, consideration of the historic craftsmanship and detailing and implementing them in the renewal wherever visible, supervision of the roofers or maintenance personnel to assure preservation of historic fabric and proper understanding of the scope and detailing of the project, consideration of alternative materials where the original cannot be used, and cyclical maintenance program to assure that the staff understands how to take care of the roof and of the particular trouble spots to safeguard. With these points in mind, it will be possible to preserve the architectural character and maintain the physical integrity of the roofing on a historic building.

Kibble-Zurek Mechanism and Finite-Time Scaling

description: The Kibble-Zurek (KZ) mechanism has been applied to a variety of systems ranging from low temperature Bose-Einstein condensations to grand unification scales in particle physics and cosmology and from classical phase transitions to quantum phase transitions. Here we show that finite-time scaling (FTS) provides a detailed improved understanding of the mechanism. In particular, the finite time scale, which is introduced by the external driving (or quenching) and results in FTS, is the origin of the division of the adiabatic regimes from the impulse regime in the KZ mechanism. The origin of the KZ scaling for the defect density, generated during the driving through a critical point, is not that the correlation length ceases growing in the nonadiabatic impulse regime, but rather, is that it is taken over by the effective finite length scale corresponding to the finite time scale. We also show that FTS accounts well for and improves the scaling ansatz proposed recently by Liu, Polkovnikov, and Sandvik [Phys. Rev. B {\bf 89}, 054307 (2014)]. Further, we show that their universal power-law scaling form applies only to some observables in cooling but not to heating. Even in cooling, it is invalid either when an appropriate external field is present. However, this finite-time-finite-size scaling calls for caution in application of FTS. Detailed scaling behaviors of the FTS and finite-size scaling, along with their crossover, are explicitly demonstrated, with the dynamic critical exponent $z$ being estimated for two- and three-dimensional Ising models under the usual Metropolis dynamics. These values of $z$ are found to give rise to better data collapses than the extant values do in most cases but take on different values in heating and cooling in both two- and three-dimensional spaces.

description: Georg Philipp Telemanns Kantate 'Der Herr ist König' (nicht in TWV) dürfte für die Leipziger Ratswahl im August 1722 entstanden sein, als sich der Komponist anlässlich seiner Bewerbung um das Thomaskantorat in der Stadt aufhielt. Die Kantate liegt in einer von Johann Christian Köpping, Johann Andreas Kuhnau, Christian Gottlob Meißner und Johann Sebastian Bach vermutlich zum Reformationsfest 1724 angefertigten Partitur vor. Als Vorlage diente offenbar ein unvollständiger Stimmensatz, in dem nicht nur die 2. Violine, Trompeten und Pauken fehlten, sondern auch die Stimmen von Alt und Tenor unvollständig waren und deshalb mehr oder weniger frei ergänzt werden mussten.

description: HTTP-based Trojan is extremely threatening, and it is difficult to be effectively detected because of its concealment and confusion. Previous detection methods usually are with poor generalization ability due to outdated datasets and reliance on manual feature extraction, which makes these methods always perform well under their private dataset, but poorly or even fail to work in real network environment. In this paper, we propose an HTTP-based Trojan detection model via the Hierarchical Spatio-Temporal Features of traffics (HSTF-Model) based on the formalized description of traffic spatio-temporal behavior from both packet level and flow level. In this model, we employ Convolutional Neural Network (CNN) to extract spatial information and Long Short-Term Memory (LSTM) to extract temporal information. In addition, we present a dataset consisting of Benign and Trojan HTTP Traffic (BTHT-2018). Experimental results show that our model can guarantee high accuracy (the F1 of 98.62%-99.81% and the FPR of 0.34%-0.02% in BTHT-2018). More importantly, our model has a huge advantage over other related methods in generalization ability. HSTF-Model trained with BTHT-2018 can reach the F1 of 93.51% on the public dataset ISCX-2012, which is 20+% better than the best of related machine learning methods.

description: A 3D thermoelectric numerical model is used to investigate different internal heat loss mechanisms for a thermoelectric generator with bismuth telluride p- and n-legs. The model considers all thermoelectric effects, temperature dependent material parameters and simultaneous convective, conductive and radiative heat losses, including surface to surface radiation. For radiative heat losses it is shown that for the temperatures considered here, surface to ambient radiation is a good approximation of the heat loss. For conductive heat transfer the module efficiency is shown to be comparable to the case of radiative losses. Finally, heat losses due to internal natural convection in the module is shown to be negligible for the millimetre sized modules considered here. The combined case of radiative and conductive heat transfer resulted in the lowest efficiency. The optimized load resistance is found to decrease for increased heat loss. The leg dimensions are varied for all heat losses cases and it is shown that the ideal way to construct a TEG module with minimal heat losses and maximum efficiency is to either use a good insulating material between the legs or evacuate the module completely, and use small and wide legs closely spaced.

description: Malicious communication behavior is the network communication behavior generated by malware (bot-net, spyware, etc.) after victim devices are infected. Experienced adversaries often hide malicious information in HTTP traffic to evade detection. However, related detection methods have inadequate generalization ability because they are usually based on artificial feature engineering and outmoded datasets. In this paper, we propose an HTTP-based Malicious Communication traffic Detection Model (HMCD-Model) based on generated adversarial flows and hierarchical traffic features. HMCD-Model consists of two parts. The first is a generation algorithm based on WGAN-GP to generate HTTP-based malicious communication traffic for data enhancement. The second is a hybrid neural network based on CNN and LSTM to extract hierarchical spatial-temporal features of traffic. In addition, we collect and publish a dataset, HMCT-2020, which consists of large-scale malicious and benign traffic during three years (2018-2020). Taking the data in HMCT-2020(18) as the training set and the data in other datasets as the test set, the experimental results show that the HMCD-Model can effectively detect unknown HTTP-based malicious communication traffic. It can reach F1 = 98.66% in the dataset HMCT-2020(19-20), F1 = 90.69% in the public dataset CIC-IDS-2017, and F1 = 83.66% in the real traffic, which is 20+% higher than other representative methods on average. This validates that HMCD-Model has the ability to discover unknown HTTP-based malicious communication behavior.

description: Multiple input multiple output techniques are considered attractive for future wireless communication systems, due to the continuing demand for high data rates, spectral efficiency, suppress interference ability and robustness of transmission. MIMO-OFDM is very helpful to transmit high data rate in wireless transmission and provides good maximum system capacity by getting the advantages of both MIMO and OFDM. The main problem in this system is that increase in number of transmit and receive antennas lead to hardware complexity. To tackle this issue, an effective optimal transmit antenna subset selection method is proposed in paper with the aid of Adaptive Mutation Genetic Algorithm (AGA). Here, the selection of transmit antenna subsets are done by the adaptive mutation of Genetic Algorithm in MIMO-OFDM system. For all the mutation points, the fitness function are evaluated and from that value, best fitness based mutation points are chosen. After the selection of best mutation points, the mutation process is carried out, accordingly. The implementation of proposed work is done in the working platform MATLAB and the performance are evaluated with various selection of transmit antenna subsets. Moreover, the comparison results between the existing GA with mutation and the proposed GA with adaptive mutation are discussed. Hence, using the proposed work, the selection of transmit antenna with the maximum capacity is made and which leads to the reduced hardware complexity and undisturbed data rate in the MIMO-OFDM system

description: Adolescents ages 10–15 experience dramatic changes in their biological, cognitive, emotional, and social development as well as in their physical and social environments. These include the physiological and psychological changes associated with puberty; further development of the brain; changes in family, peer, and romantic relationships; and exposure to new societal and cultural influences. During this period, many adolescents also begin to use alcohol. Alcohol use during adolescence has adverse effects on the body and increases the risk of alcohol dependence later in life. To better understand why some children drink whereas others do not, researchers are examining nonspecific and alcohol-specific factors that put adolescents at risk for, or which protect them from, early alcohol use and its associated problems. Nonspecific risk factors include certain temperamental and personality traits, family factors, and nonnormative development. Examples of nonspecific protective factors include certain temperamental characteristics, religiosity, and parenting factors (e.g., parental nurturance and monitoring). Among the most influential alcohol-specific risk and protective factors are a family history of alcoholism and the influences of siblings and peers, all of which shape an adolescent’s expectancies about the effects of alcohol, which in turn help determine alcohol use behaviors.
Die Temperierung der Divi Blasii-Orgel in Mühlhausen

description: Die Frage, welche Temperatur Johann Sebastian Bach bevorzugte, ist zwar unlösbar. Darlegen lassen sich allerdings die Temperaturen von Orgeln, die Bach tatsächlich vorfand - so auch in Mühlhausen. Dort existierte eine Orgel in einer Temperatur nach Andreas Werckmeister, vermutlich Werckmeister III. Für diese Stimmung hatte Johann Georg Ahle die Bedingungen geschaffen. Wenn also ein Einfluss Ahles auf Bach auf dem Gebiet der Figurenlehre nicht nachzuweisen ist, so doch wenigstens indirekt auf dem der Temperatur.

description: Female offending has become one of the topical issues in the Nigerian mass media. It is not news that females are engaged in crimes even though they are often perceived as harmless, meek, weak and in need of protection. The way female offenders are portrayed in the mass media in Nigeria and elsewhere should be of concern to feminist criminologists, media sociologists and development scholars. This issue has hardly received scholarly attention. Both males and females share the propensity to commit crime regardless of the gender differences. Available literature and statistics indicate that they are both actively involved in crime and the frequency of committal by the males is more than the females. Deploying the feminist theory as its theoretical parameter, this longitudinal study examined the portrayal of female offenders in the mass media in Nigeria. The study heavily relied on secondary sources of data collection from the National Bureau of Statistics (NBS), Nigerian Correctional Service (NCoS), print and electronic media and academic journals. Data was analyzed based on content analysis. The results indicated that though females are in all the categories of offences but their numbers are almost insignificant compared to that of the males. It further established that the highest percentage differences in male and female offending is not more than 6.4% for the females and 93.7% for the males from all the categories of offences analyzed within a period of 6 years in Nigeria (2010-2016). The study, therefore, recommended, among others, that the mass media presentation of offences should be devoid of biased gender reporting.

Detecting gravity modes in the solar $^8B$ neutrino flux

description: The detection of gravity modes produced in the solar radiative zone has been a challenge in modern astrophysics for more than 30 yr and their amplitude in the core is not yet determined. In this Letter, we develop a new strategy to look for standing gravity modes through solar neutrino fluxes. We note that due to a resonance effect, the gravity modes of low degree and low order have the largest impact on the $^{8}B$ neutrino flux. The strongest effect is expected to occur for the dipole mode with radial order $2$, corresponding to periods of about 1.5 hr. These standing gravity waves produce temperature fluctuations that are amplified by a factor of 170 in the boron neutrino flux for the corresponding period, in consonance with the gravity modes. From current neutrino observations, we determine that the maximum temperature variation due to the gravity modes in the Sun's core is smaller than $5.8\times 10^{-4}$. This study clearly shows that due to their high sensitivity to the temperature, the $^8B$ neutrino flux time series is an excellent tool to determine the properties of gravity modes in the solar core. Moreover, if gravity mode footprints are discovered in the $^{8}B$ neutrino flux, this opens a new line of research to probe the physics of the solar core as non-standing gravity waves of higher periods cannot be directly detected by helioseismology but could leave their signature on boron neutrino or on other neutrino fluxes.

The effect of concurrent geometry and roughness in interacting surfaces

description: We study the interaction energy between two surfaces, one of them flat, the other describable as the composition of a small-amplitude corrugation and a slightly curved, smooth surface. The corrugation, represented by a spatially random variable, involves Fourier wavelengths shorter than the (local) curvature radii of the smooth component of the surface. After averaging the interaction energy over the corrugation distribution, we obtain an expression which only depends on the smooth component. We then approximate that functional by means of a derivative expansion, calculating explicitly the leading and next-to-leading order terms in that approximation scheme. We analyze the resulting interplay between shape and roughness corrections for some specific corrugation models in the cases of electrostatic and Casimir interactions.

description: This memorandum provides documentation for construction of a 2,800 square foot warehouse in the Randolph Field Historic Landmark District. A determination of "no adverse effect" is based on the principle that new construction in historic districts is often necessary. The proposed new structure will be differentiated from the old, and it shall be compatible with the massing size, scale, and architectural features to protect the historic integrity of its environment.

description: With increased public awareness of the early signs and recent American Academy of Pediatrics recommendations that all 18- and 24-month-olds be screened for autism spectrum disorders, there is an increasing need for diagnostic assessment of very young children. However, unique challenges exist in applying current diagnostic guidelines for autism spectrum disorders to children under the age of 2 years. In this article, we address challenges related to early detection, diagnosis, and treatment of autism spectrum disorders in this age group. We provide a comprehensive review of findings from recent studies on the early development of children with autism spectrum disorders, summarizing current knowledge on early signs of autism spectrum disorders, the screening properties of early detection tools, and current best practice for diagnostic assessment of autism spectrum disorders before 2 years of age. We also outline principles of effective intervention for children under the age of 2 with suspected/confirmed autism spectrum disorders. It is hoped that ongoing studies will provide an even stronger foundation for evidence-based diagnostic and intervention approaches for this critically important age group.
