  • The Golden Cross is commonly seen as a buy signal in financial markets, but its reliability for predicting stock price movements is limited due to market volatility. This paper introduces a time-invariant approach that considers the Golden Cross as a singular event. Utilizing LSTM neural networks, we forecast significant stock price changes following a Golden Cross occurrence. By comparing our approach with traditional time series analysis and using a confusion matrix for classification, we demonstrate its effectiveness in predicting post-event stock price trends. To conclude, this study proposes a model with a precision of 83%. By utilizing the model, investors can alleviate potential losses, rather than making buy decisions under all circumstances following a Golden Cross event.

  • These experiments were conducted to determine the change of sugar content during germination in corn, which were analyzed by using HPLC. Germination percentage and growth rate of Golden cross bantam 70 were higher than those of Suweon 19. The emergences of radicle and plumule of Golden cross bantam 70 were faster compared to those of Suweon 19. Three major components, sucrose, glucose and fructose, were detected during germination. Content of sucrose in two tested hybrids decreased rapidly as time passes. In embryo of Suweon 19, the content of sucrose was 38.92% on 12 hours after incubation but decreased to 4.52% on 72 hours. In that of Golden cross bantam 70, it decreased rapidly more than Suweon 19 from 53.03% on 12 hours to 8.18% on 72 hours. On the other hand, the contents of glucose and fructose increased.

  • Cephalopods, such as the Japanese flying squid Todarodes pacificus and golden cuttlefish Sepia esculenta, are an important food source for all toothed whales, particularly bottlenose dolphins in costal and offshore waters around the Korean Peninsula. A controlled laboratory experiment was conducted to investigate the broadband acoustic backscattering from live individuals of these two cephalopod species using linear chirp signals (100-200 kHz). The backscattered echo signal was measured at about 1° intervals from -45° (head down) to +45° (head up) in the dorsal plane. The species-specific, frequency-dependent scattering characteristics were investigated by comparing the relationship between the wavelength-normalized backscattering cross-section (σ/λ2) and the wavelength-normalized fish length L/λ for each species. The estimated σ/λ2 value for Japanese flying squid was 9.51 at an L/λ range of 12.79-30.27 (mean, 21.26). This was approximately 7% of the σ/λ2 value (136.1) for golden cuttlefish at an L/λ range of 9.07-25.49 (mean, 15.77).

  • Biographical film is a genre narrativizing the actual person and history, and reproducing the character and history in a biographical film is in a dimension different from a film focused on a fiction. Discussion between these methods of narrative composition and image reproduction in a biographical film is also, in line with artistic/aesthetic problems and ethical/philosophical theses of the film text. This study discusses the phase of the way of reproduction of the actual person, $Xi{\bar{a}}o$ $H{\acute{o}}ng$ in the biographical film, The Golden Era and the time she lived in a biographical film and how the audience's discussion of the film and socio-cultural discourse differ depending on their attitude towards the cinematic introspection of the text. The narrative structure, the method of image reproduction and cinematic devices of the film, The Golden Era are completely off the point of the general format of the traditional biographical film. In The Golden Era, $Xi{\bar{a}}o$ $H{\acute{o}}ng$ and the history which she lived in did not revive depending on an omniscient subject's selective statement and meta-film structure. Ann Hui removed general, mythic images of $Xi{\bar{a}}o$ $H{\acute{o}}ng$ formed in the field of traditional Chinese culture and reproduced her through multilateral visions of a real, fictional narrator. Each spectator's judgment and interpretation of the film intervene in the multi-layered and sparse descriptions of the actual person's images and the era of the characters. Through this, it is possible to approach the uniqueness and authenticity a historical character, $Xi{\bar{a}}o$ $H{\acute{o}}ng$ and to have an opportunity of multi-layered reflection on how to secure a critical distance and make a perception in historical judgment.

  • Golden-rule like formulas have been used without theoretical basis to calculate the resonance lifetimes and final state distributions in the predissociation of van der Waals molecules. Here we present their theoretical basis by extending Fano's configuration interaction theory. Such extensions were independently done by Farnonux [Phys. Rev. 1985, 25, 287] but his work, unfortunately, was not well known outside some small group of people in the field of Auger spectroscopy. Since my extension is easier to understand than his, it is presented here. Theoretical basis of Golden rule like formulas used in the predissociation of van der Waals molecules was obtained by using such extensions. Factors responsible for several aspects of predissociation dynamics, such as variations of dynamics as functions of resonance lifetimes, or variations in shapes of final quantum state distributions of photofragments around resonances, were identified. Parameters, or dynamical information that could be obtained from the measurement of partial cross section spectra were accordingly determined. The theory was applied to the vibrational predissociation of triatomic van der Waals molecules and its result was compared with those calculated by close-coupling method. An example where Golden-rule like expression fails and branching ratios vary greatly around a resonance was considered.

  • Changes in the contents of sugars and soluble solids and flavor rate of cooked kernels of three sweet com hybrids (Great Bell, Danok 1, and Golden Cross Bantam) and a super sweet corn hybrid (Crisp Super Sweet 720) were observed from 15 days after silking (DAS) to 27 or 33 DAS in 1985 and 1986 to determine the optimum harvest time. Sucrose content in all hybrids and fructose and glucose contents of Crisp Super Sweet 720 increased from 15 DAS to 21 or 24 DAS and then decreased. However, in the three sweet corn hybrids both fructose and glucose contents were highest at 15 DAS and then continuously decreased with maturity. At harvest time the major sugar component was sucrose and the highest total sugar content of Crisp Super Sweet 720 was 2-3 times higher than that of three sweet corn hybrids. Soluble solids were continuously increased with maturity in three sweet com varieties, but that of Crisp Super Sweet 720 increased up to 24 DAS, maintained the level through 30 DAS and then decreased. At harvest time soluble solids of three sweet com varieties were much higher than that of Crisp Super Sweet 720. The optimum harvest time seems to be about 27 DAS considering flavor rate and marketing conditions although the total sugar content was lower than those of earlier harvests. Soluble solids but not total sugars were positively correlated with the flavor of cooke6 com harvested at different growth stages in the same variety. Total sugars were not correlated with soluble solids or negatively correlated depending on hybrids.

This cultivar was yellow in color, single in flower type for the spray type cut flower. Its capitulum was 2.4cm in diameter, and had 23.2 head per stem in autumn. Its ray floret was green central zone. The days to flowering under the short day treatment is about 49 days in spring season, and "Golden Eye" showed the vase life of 25.7 days in autumn. This cultivar was registered for a commercialization in 2008.
