Pengaruh Efektifitas Media Iklan Kartu Seluler Xl pada PT Xl Axianta di Jakarta Barat
Berdasarkan hasil analisis CRI yang telah diuji, iklan kartu selular XL melalui media televisi termasuk dalam kategori cukup efektif. Hal tersebut disebabkan banyaknya responden yang melihat iklan di media televisi, namun jumlah responden yang tertarik sampai proses pembelian tidak terlalu tinggi. Ini menunjukan bahwa iklan di media televisi sudah maksimal dalam menarik perhatian konsumen namun pesan yang disampaikan tidak membuat konsumen membeli produknya.Sedangkan untuk membeli produk, mereka tidak tertarik pada promosinya karena sudah memiliki pilihan kartu selular yang lain. Berdasarkan hasil analisis CRI yang telah diuji, iklan kartu selular XL melalui media surat kabar termasuk dalam kategori efektif karena didukung dari informasi yang didapatkan responden pada saat membaca, lebih jelas dan terperinci promosi yang sedang berlangsung serta syarat dan ketentuan yang ada. Iklan di surat kabar tidak setiap hari diterbitkan, namun sekali diterbitkan banyak konsumen yang tertarik dan melakukan pembelian
The effect of environmental factors on the physiology, yield and oil composition of safflower (Carthamus tinctorius L.)
This study investigated the effects of drought, nitrogen fertilizer and elevated CO2 and its interaction with nitrogen fertilizer on the physiology, growth, and production of the oil crop safflower (Carthamus tinctorius L.) in a semi-controlled glasshouse environment.
Three levels of water stress were imposed: rosette (mid-season drought), stem elongation (terminal drought) and rosette to maturity (mid-season + terminal drought). Results indicated that all drought treatments imposed reduced stomatal conductance, but after the relief of mid-season drought plants recovered and as a result there were no significant differences from control in terms of yield components (branch and capital number) and seed number. Terminal drought and mid–season + terminal drought induced significant reductions in branch number (48% and 50%), in capitula number (33% and 67%), in seed number (89% and 92%), in above ground dry weight (30% and 54%) and in individual fresh seed weight (90% and 94%) respectively. However, water stress treatments had no significant effect on the maximum quantum efficiency of PSII (Fv/Fm) in dark adapted leaves compared with the control.
Levels nitrogen fertilizer was studied equivalent to 0, 25, 50, 75, 100, 125, 150, 175 kg N ha-1 were evaluated. Safflower responded incrementally to increasing nitrogen applied in a curvilinear asymptotic fashion. Assimilation rate (42%), transpiration rate (32%), stomatal conductance (52%) and LAI (42%) increased

up to 100 kg N ha-1 compared with the control. The above ground dry weight and seed yield associated with WUE continued to increase with each increment in nitrogen rate and above ground dry weight (42%), individual seed fresh weight (76%) and WUE (41%) increased up to 175 kg N ha-1 compared with the control.
The effect of elevated CO2, (1000 μmol mol-1) significantly increased assimilation rate (27%) reduced stomatal conductance (29%) and transpiration rate (18%), increased LAI (28%) and above ground dry weight (51%) when measured at anthesis compared with ambient (400 μmol mol-1). At the same time plant organ N content was reduced. At harvest, elevated CO2 increased above ground dry weight (42%) and individual fresh seed weight (49%).
The interaction effect of elevated CO2 with nitrogen input was investigated using four nitrogen levels equivalent to 25, 75,125 and 175 kg ha-1. The nitrogen response rate was raised by elevated CO2 equally at each nitrogen application rate so that there was no significant interaction effect between the two for most parameters measured. In this way both CO2 and nitrogen were acting as “fertilizers”.
Overall the results showed that despite being put forward as a drought resistant crop for low input agricultural systems safflower is capable of responding positively to well irrigate and well fertilized conditions. Furthermore under conditions of elevated CO2 it can be expected to increase its yield potential but to achieve this will require a higher degree of nitrogen fertilization. CO2 is capable of substituting for up to 100 kg N ha-1 without a decline in yield and this shows that CO2 is the primary limiting factor in safflower assimilation.

Seed oil content and its fatty acid profile appeared to be relatively stable and were not affected drastically by either nitrogen fertilization or elevated CO2.This demonstrated the integrity of the oil filling process during seed fill and emphasized that this is primarily under genetic control with relatively little influence from environmental parameters.Iraqi Ministry of Higher Educatio
Identifying Alzheimer Disease Dementia Levels Using Machine Learning Methods
Dementia, a prevalent neurodegenerative condition, is a major manifestation
of Alzheimer's disease (AD). As the condition progresses from mild to severe,
it significantly impairs the individual's ability to perform daily tasks
independently, necessitating the need for timely and accurate AD
classification. Machine learning or deep learning models have emerged as
effective tools for this purpose. In this study, we suggested an approach for
classifying the four stages of dementia using RF, SVM, and CNN algorithms,
augmented with watershed segmentation for feature extraction from MRI images.
Our results reveal that SVM with watershed features achieves an impressive
accuracy of 96.25%, surpassing other classification methods. The ADNI dataset
is utilized to evaluate the effectiveness of our method, and we observed that
the inclusion of watershed segmentation contributes to the enhanced performance
of the models
Effectiveness of neuromuscular conditioning to prevent anterior cruciate ligament injuries in female athletes: a critical synthesis of literature
Background and Purpose: Anterior cruciate ligament (ACL) injuries are common among female athletes. The purpose of this literature review was to assess the effectiveness of neuromuscular conditioning to modify biomechanical risk factors for ACL injury.
METHOD: A structured literature search was conducted to identify primary research articles. Articles were graded according to their strength of evidence and a qualitative literature review was completed.
RESULTS: Seven primary research studies were available for analysis that documented the effects of neuromuscular conditioning (range of evidence grades: 1B to 3B). Lower limb kinematics, lower limb kinetics, and incidence of tears were the primary outcomes measures.
DISCUSSION: The effectiveness of neuromuscular training to modify the theoretical and actual risks for ACL injury is promising but not yet adequately confirmed in the literature.
CLINICAL RELEVANCE: Preliminary evidence indicates the effectiveness of neuromuscular training to reduce ACL injury risk, although mechanisms and optimal dosage of exercise remain unclear
Sim-T: Simplify the Transformer Network by Multiplexing Technique for Speech Recognition
In recent years, a great deal of attention has been paid to the Transformer
network for speech recognition tasks due to its excellent model performance.
However, the Transformer network always involves heavy computation and large
number of parameters, causing serious deployment problems in devices with
limited computation sources or storage memory. In this paper, a new lightweight
model called Sim-T has been proposed to expand the generality of the
Transformer model. Under the help of the newly developed multiplexing
technique, the Sim-T can efficiently compress the model with negligible
sacrifice on its performance. To be more precise, the proposed technique
includes two parts, that are, module weight multiplexing and attention score
multiplexing. Moreover, a novel decoder structure has been proposed to
facilitate the attention score multiplexing. Extensive experiments have been
conducted to validate the effectiveness of Sim-T. In Aishell-1 dataset, when
the proposed Sim-T is 48% parameter less than the baseline Transformer, 0.4%
CER improvement can be obtained. Alternatively, 69% parameter reduction can be
achieved if the Sim-T gives the same performance as the baseline Transformer.
With regard to the HKUST and WSJ eval92 datasets, CER and WER will be improved
by 0.3% and 0.2%, respectively, when parameters in Sim-T are 40% less than the
baseline Transformer
