SISTEM PERAMALAN KEBUTUHAN STOK BARANG MENGGUNAKAN METODE TREND MOMENT (2017)

Sebuah perusahaan tidak lepas dari yang namanya penjualan terutama perusahaan distribusi. Selain proses penjualan harus didukung oleh ketersediaan stok barang. Permintaan pasar yang berubah setiap harinya menuntut para distributor lebih detail dalam perencanaan strategi untuk meningkatkan penjualan setiap harinya. Salah satu yang dapat dilakukan pihak manajemen distributor adalah melakukan peramalan jualan (sales forecasting). Manfaat peramalan penjualan dapat menjadi dasar untuk menghitung budgeting pembelian di periode berikutnya, membuat perencanaan, dan alat untuk mengukur seberapa besar tingkat pencapaian target. Penelitian ini merancang system peramalan perhari dan perbulan menggunakan metode peramalan Trend Moment.Peramalan menggunakan metode Trend Moment masih harus dihaluskan lagi dengan perhitungan indeks musiman. Penelitian ini merancang system peramalan menggunakan data penjualan. Hasil yang diperoleh yaitu peramalan penjualan harian dan bulanan. Pada peramalan harian menggunakan tanggal, bulan dan tahun sebagai pilihan waktu yang akan diramalkan. Hasil peramalan bulanan terutama harian diharapkan mampu mendukung perusahaan dalam merencanakan strategi dimasa yang akan datang dengan lebih rinci berdasarkan perubahan setiap harinya.Masih terdapat selisih antara nilai aktual penjualan dengan hasil peramalan menggunakan metode Trend Moment. Menggunakan data dengan jumlah yang berbeda sebagai data peramalan, sangat berpengaruh terhadap hasil peramalan. Semakin banyak jumlah data yang dimasukkan akan semakin sedikit selisih antara nilai aktual dengan hasil peramalan.

Barresi and O. Hindsgaul to all carbohydrate chemists now has a novel reply, which can be described by the sequence in Equation (a).
Tea Triterpenoidal Saponins from the Roots ofCamellia sinensisHave Inhibitory Effects against Alcohol Dehydrogenase (2011)

Ten new polyhydroxyolean-12-ene pentacyclic triterpenoidal saponins, named rogchaponins 1-10, were isolated from the methanolic extract of the roots of Camellia sinensis by a series of chromatographic methods (silica gel flash column and C18 MPLC followed by C18 HPLC). Their structures were established by 1D and 2D-NMR techniques along with IR and HR-TOF-MS. Rogchaponins R4 ( 4) and R5 (5) showed inhibitory activities against yeast alcohol dehydrogenase (ADH) with IC (50) values of 16.1 ± 3.2 and 15.4 ± 3.3 µM, respectively. A 4-methylpyrazole positive control exhibited an IC (50) of 2750 ± 50 µM. However, the saponins showed no inhibitory activity against yeast aldehyde dehydrogenase (ALDH).
Comparative Study of Energy Efficiency of Glazing Systems for Residential and Commercial Buildings (2013)

The 2011 Building Energy Databook (DOE, 2011) reported that buildings use approximately 40% of the nation's total energy use. One method of reducing this value is to replace inefficient single glazed window units with their newer, energy efficient counterparts. This study involved the investigation of several different glazing solutions. A comparative energy investigation of numerous products on the market was performed using multiple different software packages for a model residential and commercial building in five different climates across the United States. The paper will introduce the advanced glazing technologies used in the study, present the details of the selected residential and commercial buildings modeled for energy analysis, discuss the results of the thermal property evaluation and energy analysis, and present the conclusions derived from the study.
Fic domain‐catalyzed adenylylation: Insight provided by the structural analysis of the type IV secretion system effector BepA (2011)

Numerous bacterial pathogens subvert cellular functions of eukaryotic host cells by the injection of effector proteins via dedicated secretion systems. The type IV secretion system (T4SS) effector protein BepA from Bartonella henselae is composed of an N-terminal Fic domain and a C-terminal Bartonella intracellular delivery domain, the latter being responsible for T4SS-mediated translocation into host cells. A proteolysis resistant fragment (residues 10-302) that includes the Fic domain shows autoadenylylation activity and adenylyl transfer onto Hela cell extract proteins as demonstrated by autoradiography on incubation with α-[(32)P]-ATP. Its crystal structure, determined to 2.9-Å resolution by the SeMet-SAD method, exhibits the canonical Fic fold including the HPFxxGNGRxxR signature motif with several elaborations in loop regions and an additional β-rich domain at the C-terminus. On crystal soaking with ATP/Mg(2+), additional electron density indicated the presence of a PP(i) /Mg(2+) moiety, the side product of the adenylylation reaction, in the anion binding nest of the signature motif. On the basis of this information and that of the recent structure of IbpA(Fic2) in complex with the eukaryotic target protein Cdc42, we present a detailed model for the ternary complex of Fic with the two substrates, ATP/Mg(2+) and target tyrosine. The model is consistent with an in-line nucleophilic attack of the deprotonated side-chain hydroxyl group onto the α-phosphorus of the nucleotide to accomplish AMP transfer. Furthermore, a general, sequence-independent mechanism of target positioning through antiparallel β-strand interactions between enzyme and target is suggested.
Generation of plasma torch by 2.45 GHz microwaves from a solid-state power amplifier (2019)

High efficiency electrodeless plasma at atmospheric pressure was generated using 2.45 GHz microwaves with a solid state power amplifier (SSPA) to achieve greater plasma efficiency in a type WR340 rectangular resonator, in comparison with magnetron. Plasma flames were sustained in a discharge tube with an inner diameter of 26 mm by swirl flow. With an applied power of 3.3 kW and the injection of 50 lpm swirl air, the plasma flame length of the SSPA was 630 mm, demonstrating an almost 30% increase compared with the magnetron flame length. Subsequently, the Q factors, indicating energy efficiencies of the magnetron and SSPA, were calculated using frequency analysis data. The obtained Q factors demonstrated an increase in plasma efficiency by almost one order of magnitude with the SSPA on the WR340 resonator as compared to the magnetron.
Staged repair of esophageal atresia: Pouch approximation and catheter-based magnetic anastomosis (2014)

Esophageal atresia (EA) without tracheoesophageal fistula is characterized typically by a long gap between the discontinuous upper and lower esophageal pouches. In these challenging patients, initial esophagoesophagostomy is often not possible due to excessive tension produced when approximating the two pouches. This tension poses significant risk for pouch retraction, anastomotic leak, mediastinitis, and subsequent esophageal stricture. Consequently, multiple strategies exist to induce pouch lengthening and to achieve full continuity of native esophageal tissue, which if not accomplished, requires interpositions of stomach, small bowel, or colon to establish deglutition. One strategy involves a two-staged approach: first, after a period of growth into early infancy, the two esophageal pouches are suture-approximated without anastomosis, and second, repeat surgery is performed to establish luminal continuity once tension between the pouches has resolved. Esophageal growth and continuity are thereby achieved. Here, we describe an innovative, staged treatment approach for long-gap EA in two premature babies who initially underwent suture-approximation of the esophageal pouches at 3 months of age, followed by catheter-based magnetic compression anastomosis 10 weeks later. In both babies, the magnetic procedure allowed preservation of the gained full esophageal length, established successful esophageal canalization, created a leak-free anastomosis, and prevented the need for additional thoracotomy to accomplish these goals.
Frequency of human immunodeficiency virus (HIV) infection among contemporary anti‐HIV‐1 and anti‐HIV‐½ supplemental test‐ indeterminate blood donors (1996)

Contemporary blood donors classified as indeterminate in supplemental HIV testing are infrequently infected with HIV. Donors whose follow-up samples test negative in anti-HIV-1/2 EIAs and negative or persistently indeterminate in Western blots should be considered eligible for reinstatement.
Cytotoxic 4-Phenylcoumarins from the Leaves of Marila pluricostata (2005)

Bioassay-guided fractionation of the CH(2)Cl(2) extract of the leaves of Marila pluricostata led to the isolation of 17 naturally occurring 4-phenylcoumarins, three of them, 5-hydroxy-8,8-dimethyl-4-phenyl-9,10-dihydro-8H-pyrano-[2,3-f]chromen-2-one (1), 5-hydroxy-8,8-dimethyl-4-phenyl-6-propionyl-9,10-dihydro-8H-pyrano-[2,3-f]chromen-2-one (2), and 5,7-dihydroxy-8-(3-methylbut-2-enyl)-4-phenylchromen-2-one (3), are new natural compounds; the remaining (4-17) are known mammea-type coumarins. Their structures were established by spectroscopic means. All compounds were tested in cytotoxicity assays against the MCF-7, H-460, and SF-268 human cancer cell lines.
Phenotypic characterization of lymphocytic cell infiltrates into the testes of rats undergoing autoimmune orchitis (1993)

Experimental autoimmune orchitis (EAO) was induced in adult Wistar rats by active immunization with a testicular homogenate (TH) and adjuvants. Fifty per cent of the immunized rats developed EAO. Testicular damage became evident at 50 days after the primary immunization and increased in severity at 80 days. Phenotypic characterization of T-cell subsets (CD4+ and CD8+) and Ia+ cells was performed on cryostat sections of testis obtained from normal rats, rats immunized with adjuvant (control group) and rats immunized with TH and adjuvants (experimental group) at 50 and 80 days. Labelled cells were only detected in the interstitial area; no labelled cells were observed inside the seminiferous tubules with any of the monoclonal antibodies used (W3/25, OX-8, OX-6). A significant increase in the numbers of CD4+ and CD8+, as well as of Ia+ cells, were observed in the testis of rats with severe EAO at 80 days after the first immunization. Rats of the same experimental group without testicular damage showed no major differences compared to rats from the control group, with the exception of a lower number of CD8+ cells. Variations in the lymphocyte subsets in lymph nodes draining the site of immunization showed the opposite pattern to that observed in the testis. In conclusion, these data suggest the traffic of specifically sensitized lymphocytes from lymph nodes to the testis and an active role of CD4+, CD8+ and Ia+ cells in the pathogenesis of EAO in the rat.
Non-Hermitian formulation of interference effect in scattering experiments (2000)

Non-Hermitian quantum mechanics allows one to calculate a physical observable, e.g., scattering cross section, as a sum over a finite number of discrete resonance states. The coefficients in the sum can get complex and negative values even in cases where conventional scattering theory predicts real positive coefficients only. Consequently, structure (or absence of structure) in scattering cross section can be obtained as a result of interference between a small number of discrete resonance states; whereas, conventional scattering theory would require integration over the continuum of scattering states and therefore it is a heavy numerical task. We show here that in electron scattering experiments the interference between overlapping broad resonances leads to oscillations in the phase of transition probability amplitude and to enhancement of the transition state lifetime due to nuclear motion.
SWIR-MWIR electron fluorescence measurements in N2/O2 and air. Environmental research papers (1978)

The infrared fluorescence of electron irradiated room air and mixtures of N2/O2 has been observed over the spectral range of 1600-6700/cm. Dominant spectral features include the NO fundamental and first overtone bands as well as the CO2(nu3) and N2O(nu3) fundamental bands. Comparisons between the spectra observed in room air and laboratory N2/O2 mixtures are provided. (Author)
Phenotypic and functional analysis of T-cell precursors in the human fetal liver and thymus: CD7 expression in the early stages of T- and myeloid-cell development (1993)

It has been proposed that the CD7 molecule is the first antigen expressed on the membrane of cells committed to the T-cell lineage during human fetal T-cell ontogeny. To further identify the pre-T cell subpopulation that migrates to the thymus early in ontogeny, we analyzed the phenotypic and functional characteristics of the fetal liver populations separated on the basis of CD7 expression. Three populations expressing different levels of CD7 were observed: CD7bright, CD7dull, and CD7-. A CD7bright population depleted of mature T, B, and myeloid cells (lineage negative, lin-) and mostly composed of CD56+ CD34- natural killer cells did not mature into T cells in a fetal thymic organ culture (FTOC) assay and was devoid of myeloid progenitors in a clonal colony-forming cell assay. In contrast, the CD7-/dull CD34+ lin- populations were capable of differentiating into phenotypically mature T cells after injection into FTOC and contained early myeloid progenitors. Here we phenotypically compared the fetal liver CD7 populations with the most immature fetal thymic subset that differentiated in the FTOC assay, namely the triple negative (TN, CD3-CD4-CD8-) thymocytes. Fetal TN lin- expressed high levels of CD34 marker and were further subdivided by their expression of CD1 antigen, because CD1- TN thymocytes express higher levels of CD34 antigen compared with CD1+ TN cells. CD1- lin -TN thymocytes are characterized by expressing high levels of CD2, CD7, and CD34 markers and dull levels of CD5, CD10, and CD28 molecules. We could not find fetal liver pre-T cells with a phenotype equivalent to that of TN thymocytes. Our data show that CD7 does not necessarily identify T-cell precursors during fetal T-cell development and strongly support the hypothesis that the acquisition of early T-cell markers as CD2, CD28, and CD5 molecules on the cell surface of T-cell progenitors takes place intrathymically.
Myocardial Energy Restoration of Ischemic Damage by Administration of Phosphoenolpyruvate during Reperfusion (1983)

The myocardial energy restoration of ischemic damage by administration of phosphoenolpyruvate during reperfusion was investigated in a paracorporeal heart model modified in the rat. Excised hearts were subjected to 15 min of complete global ischemia at ischemia at 37 degrees C before pulsatile blood reperfusion for 30 min. One group (n = 7) was supplemented with 67 mumol of phosphoenolpyruvate and 0.67 mumol of adenosine triphosphate dissolved in 10 ml of saline and another with plain saline (nonsupplemented) during reperfusion. All hearts were freeze-clamped after 30 min of reperfusion and subjected to energy content analysis. The adenylate charge potential was 0.91 +/- 0.01 (mean +/- SD) for the supplemented and 0.85 +/- 0.06 (mean +/- SD) for the nonsupplemented group. This difference was significant (p less than 0.02). Concomitantly the outflow of creatine kinase was less for the supplemented group. The translocation of phosphoenolpyruvate into the myocardial cells seems possible by blood supplementation of a lower dose of adenosine triphosphate.
Quantifying the Extent to Which Race and Gender Features Determine\n Identity in Commercial Face Recognition Algorithms (2020)

Human face features can be used to determine individual identity as well as\ndemographic information like gender and race. However, the extent to which\nblack-box commercial face recognition algorithms (CFRAs) use gender and race\nfeatures to determine identity is poorly understood despite increasing\ndeployments by government and industry. In this study, we quantified the degree\nto which gender and race features influenced face recognition similarity scores\nbetween different people, i.e. non-mated scores. We ran this study using five\ndifferent CFRAs and a sample of 333 diverse test subjects. As a control, we\ncompared the behavior of these non-mated distributions to a commercial iris\nrecognition algorithm (CIRA). Confirming prior work, all CFRAs produced higher\nsimilarity scores for people of the same gender and race, an effect known as\n"broad homogeneity". No such effect was observed for the CIRA. Next, we applied\nprincipal components analysis (PCA) to similarity score matrices. We show that\nsome principal components (PCs) of CFRAs cluster people by gender and race, but\nthe majority do not. Demographic clustering in the PCs accounted for only 10 %\nof the total CFRA score variance. No clustering was observed for the CIRA. This\ndemonstrates that, although CFRAs use some gender and race features to\nestablish identity, most features utilized by current CFRAs are unrelated to\ngender and race, similar to the iris texture patterns utilized by the CIRA.\nFinally, reconstruction of similarity score matrices using only PCs that showed\nno demographic clustering reduced broad homogeneity effects, but also decreased\nthe separation between mated and non-mated scores. This suggests it's possible\nfor CFRAs to operate on features unrelated to gender and race, albeit with\nsomewhat lower recognition accuracy, but that this is not the current\ncommercial practice.\n
Successful Integrated Engineering Service Contract in South China Sea (1996)

Abstract An Integrated Engineering Service (IES) Contract covering drilling and completion services was formed to develop two sixteen well platforms for Phillips Petroleum International Corporation Asia (PPICA) in the South China Sea. The purpose of the contract was to improve well quality and to reduce the cost and development time to PPICA by taking advantage of existing service company/lead contractor infrastructure in the area. Through a cooperative team environment, a cycle of continuous improvement has resulted in dramatically reduced drilling/ completion times, improved production, and a much lower development cost to the operator. This paper views the IES relationship from both the per-spective of the operator and the lead contractor and its sub-contractors. It reviews in detail: 1.) the project history and background (including why an IES Contract was the right fit in this case) 2.) the "Team Xijiang" structure, roles and responsibilities, and decision making process 3.) the pricing mecha-nisms and how interests are aligned through incentive pricing 4.) the continuous improvement cycle and 5.) the actual results of the project as compared to anticipated results from previous experience in the area. This new business relationship has laid important groundwork for future opportunities in the industry, for both the operator and lead contractor. An atmosphere of cooperation and trust has removed many of the. barriers that exist in a traditional buyer/supplier relationship (or even in an expanded alliance). By empowering team members to make decisions at the lowest possible level, personnel from all organizations involved are encouraged to contribute freely to the overall success of the project. The industry is continually faced with the need to improve efficiencies through unique solutions to problems. For any given circumstance, there are numerous alternatives to meet the need. In this case, employing an Integrated approach via one lead contractor, has been a great success.

Characteristics of Genomic Signatures Derived Using Univariate Methods and Mechanistically Anchored Functional Descriptors for Predicting Drug- and Xenobiotic-Induced Nephrotoxicity (2008)

ABSTRACT The ideal toxicity biomarker is composed of the properties of prediction (is detected prior to traditional pathological signs of injury), accuracy (high sensitivity and specificity), and mechanistic relationships to the endpoint measured (biological relevance). Gene expression-based toxicity biomarkers ("signatures") have shown good predictive power and accuracy, but are difficult to interpret biologically. We have compared different statistical methods of feature selection with knowledge-based approaches, using GeneGo's database of canonical pathway maps, to generate gene sets for the classification of renal tubule toxicity. The gene set selection algorithms include four univariate analyses: t-statistics, fold-change, B-statistics, and RankProd, and their combination and overlap for the identification of differentially expressed probes. Enrichment analysis following the results of the four univariate analyses, Hotelling T-square test, and, finally out-of-bag selection, a variant of cross-validation, were used to identify canonical pathway maps-sets of genes coordinately involved in key biological processes-with classification power. Differentially expressed genes identified by the different statistical univariate analyses all generated reasonably performing classifiers of tubule toxicity. Maps identified by enrichment analysis or Hotelling T-square had lower classification power, but highlighted perturbed lipid homeostasis as a common discriminator of nephrotoxic treatments. The out-of-bag method yielded the best functionally integrated classifier. The map "ephrins signaling" performed comparably to a classifier derived using sparse linear programming, a machine learning algorithm, and represents a signaling network specifically involved in renal tubule development and integrity. Such functional descriptors of toxicity promise to better integrate predictive toxicogenomics with mechanistic analysis, facilitating the interpretation and risk assessment of predictive genomic investigations.
FSPRM: A Feature Subsequence Based Probability Representation Model for Chinese Word Embedding (2021)

Chinese word embedding models capture Chinese semantics based on the character feature of Chinese words and the internal features of Chinese characters such as radical, component, stroke, structure and pinyin. However, some features are overlapping and most methods do not consider their relevance. Meanwhile, they express words as point vectors that cannot better capture different aspect semantics of Chinese words. In this paper, we propose a Feature Subsequence based Probability Representation Model (FSPRM) for learning Chinese word embeddings, in which we first integrate the morphological and phonetic features (stroke, structure and pinyin) of Chinese characters and learn their relevance by designing a feature subsequence to capture relatively comprehensive semantics of Chinese words, then feature probability distribution is proposed for capturing different aspect meanings of Chinese words based on the three internal features and probability representation by estimating its mean as the sum of feature subsequences. Chinese words with similar features may have similar semantics, then we map Chinese words to feature probability distributions and design a similarity-based objective for predicting the contextual words of the target word to learn their semantics. Extensive experiments on word analogy, word similarity, text classification and named entity recognition tasks demonstrate that the proposed method outperforms most state-of-the-art approaches.
