SITUS NEOLITIK MALLAWA MAROS, SULAWESI SELATAN (Suatu Hasil Analisis Keterkaitan antara Artefak dengan Sumber Daya Lingkungan) Neolithic Site at Mallawa Maros of South Sulawesi [A Result of Relevancy Analysis Between The Artefacts and The Environment Resources]

The Mallawa is an open site located in the eastern part of Maros, South Sulawesi. The topography of Mallawa site is wavy and took place in a hilly area. Dating of the site using C14 Analysis showed that the site is about 3550 ±130 BP and 2710 ±170 BP and 2281± 46 BP. The point of this site, besides of its plenty artifacts that signifying occupied-densely site of some hills, the site is also located nearby caves of Maros. From the perspective of periodization, Mallawa site relatively younger compared to occupancy period in Maros caves. It is likely to say that the occupancy of Mallawa cave is the further stage in development of past life that characterized by its material culture remains. Several pottery findings possesses various of interesting forms and ornaments. In this research has also found several interesting findings such as pottery fragments, beads and stone artifacts. The excavation brings out more findings then the surficial findings. Through XRD analysis, SEM and also, XRF of the pottery and soil sample shows that Mallawa pottery were made and produced by the Mallawa themselves and the people surrounding based on the fact that the pottery contains the same mineral with the soil that surrounding this site. ABSTRAKMallawa adalah situs terbuka yang terletak di bagian timur Maros, Sulawesi Selatan. Topografi situs Mallawa bergelombang dan terletak di daerah perbukitan. Pertanggalan situs dengan menggunakan Analisis C14 menunjukkan bahwa situs ini berumur sekitar 3550 ± 130 BP dan 2710 ± 170 BP dan 2281 ± 46 BP. Bagian penting dari situs ini, selain dari temuan artefak yang menandakan tempat berpenduduk padat di beberapa bukit, situs ini juga terletak di dekat gua-gua Maros. Dari segi periodisasi, situs Mallawa relatif lebih muda dibandingkan dengan masa hunian di gua Maros. Kemungkinan besar dikatakan bahwa hunian situs Mallawa merupakan tahap lanjutan dalam pengembangan kehidupan lampau yang ditandai oleh budaya materialnya. Beberapa temuan gerabah memiliki berbagai bentuk dan ornamen yang menarik. Dalam penelitian ini juga ditemukan beberapa temuan menarik seperti fragmen gerabah, manik-manik dan artefak batu. Penggalian tersebut menghasilkan lebih banyak temuan. Melalui analisis XRD, SEM dan juga, XRF dari gerabah dan sampel tanah menunjukkan bahwa gerabah Mallawa dibuat dan diproduksi di Mallawa sendiri berdasarkan fakta bahwa gerabah mengandung mineral yang sama dengan tanah di sekitar lokasi ini.
Genome Sequences of Two Pathogenic Streptococcus agalactiae Isolates from the One-Humped Camel Camelus dromedarius

ABSTRACT Streptococcus agalactiae causes a range of clinical syndromes in camels (Camelus dromedarius). We report the genome sequences of two S. agalactiae isolates that induce abscesses in Kenyan camels. These genomes provide novel data on the composition of the S. agalactiae “pan genome” and reveal the presence of multiple genomic islands.
Breast Cancer Molecular Subtypes Respond Differently to Preoperative Chemotherapy

Purpose: Molecular classification of breast cancer has been proposed based on gene expression profiles of human tumors. Luminal, basal-like, normal-like, and erbB2+ subgroups were identified and were shown to have different prognoses. The goal of this research was to determine if these different molecular subtypes of breast cancer also respond differently to preoperative chemotherapy. Experimental Design: Fine needle aspirations of 82 breast cancers were obtained before starting preoperative paclitaxel followed by 5-fluorouracil, doxorubicin, and cyclophosphamide chemotherapy. Gene expression profiling was done with Affymetrix U133A microarrays and the previously reported “breast intrinsic” gene set was used for hierarchical clustering and multidimensional scaling to assign molecular class. Results: The basal-like and erbB2+ subgroups were associated with the highest rates of pathologic complete response (CR), 45% [95% confidence interval (95% CI), 24-68] and 45% (95% CI, 23-68), respectively, whereas the luminal tumors had a pathologic CR rate of 6% (95% CI, 1-21). No pathologic CR was observed among the normal-like cancers (95% CI, 0-31). Molecular class was not independent of conventional cliniocopathologic predictors of response such as estrogen receptor status and nuclear grade. None of the 61 genes associated with pathologic CR in the basal-like group were associated with pathologic CR in the erbB2+ group, suggesting that the molecular mechanisms of chemotherapy sensitivity may vary between these two estrogen receptor–negative subtypes. Conclusions: The basal-like and erbB2+ subtypes of breast cancer are more sensitive to paclitaxel- and doxorubicin-containing preoperative chemotherapy than the luminal and normal-like cancers.
Computing Slow Manifolds of Saddle Type

Slow manifolds are important geometric structures in the state spaces of dynamical systems with multiple time scales. This paper introduces an algorithm for computing trajectories on slow manifolds that are normally hyperbolic with both stable and unstable fast manifolds. We present two examples of bifurcation problems where these manifolds play a key role and a third example in which saddle-type slow manifolds are part of a traveling wave profile of a partial differential equation. Initial value solvers are incapable of computing trajectories on saddle-type slow manifolds, so the slow manifold of saddle type (SMST) algorithm presented here is formulated as a boundary value method. We take an empirical approach here to assessing the accuracy and effectiveness of the algorithm.
Coupled Spin-Torque Nano-Oscillator-Based Computation

In this article, we present a comprehensive study of four frequency locking mechanisms in Spin Torque Nano Oscillators (STNOs) and explore their suitability for a class of specialized computing applications. We implemented a physical STNO model based on Landau-Lifshitz-Gilbert-Slonczewski equation and benchmarked the model to experimental data. Based on our simulations, we provide an in-depth analysis of how the “self-organizing” ability of coupled STNO array can be effectively used for computations that are unsuitable or inefficient in the von-Neumann computing domain. As a case study, we demonstrate the computing ability of coupled STNOs with two applications: edge detection of an image and associative computing for image recognition. We provide an analysis of the scaling trends of STNOs and the effectiveness of different frequency locking mechanisms with scaling in the presence of thermal noise. We also provide an in-depth analysis of the effect of variations on the four locking mechanisms to find the most robust one in the presence of variations.
Manuscript : CL 2002-1133 Generating Realistic ISP-Level Network Topologies

Simulations are an important tool in network research. As the selected topology often influences the outcome of the simulation, realistic topologies are needed to produce realistic simulation results. Using several similarity metrics to compare artificially generated topologies with real world topologies this letter gives hints how to use the wide-spread topology generators BRITE, TIERS and GT-ITM to create realistic topologies.
Applying Theory of Perceived Risk and Technology Acceptance Model in the Online Shopping Channel

As the advancement of technology, online shopping channel develops rapidly in recent years. According to the report of Taiwan Network Information Center, there are almost eighty percents of internet population shopping in online channel. Synthesizing insights from the previous research, this study develops the conceptual model to integrate Theory of Perceived Risk (TPR) and Technology Acceptance Model (TAM) to apply in online shopping. Using data collected from 637 respondents from online survey website, we use structural equation modeling to test measurement and structural models. The results suggest the need for consideration of perceived risk as an antecedent in the Technology Acceptance Model. The limitations and implications are discussed. Keywords—perceived risk, perceived usefulness, perceived ease of use, behavioral intention, actual purchase behavior
Sustainable Solid Waste Management in India

The present study represents that the waste generation rate in Indian cities ranges between 200 870 grams/day, depending upon the region’s lifestyle and the size of the city. The study also shows that the per capita waste generation is increasing by about 1.3% per year in India. Cities in Western India were found to be generating the least amount of waste per person, only 440 grams/day, followed by East India (500 g/day), North India (520 g/day), and South India. Southern Indian cities generate 560 grams/day, the maximum waste generation per person. States with minimum and maximum per capita waste generation rates are Manipur (220 grams/day) and Goa (620 grams/day).
Parental perceptions of fever in children.

BACKGROUND Fever is a common medical problem in children which often prompts parents to seek immediate medical care. The objective of this study was to survey parents about their knowledge and attitude concerning fever in their children. PATIENTS AND METHODS The study involved the random selection of Saudi parents who brought their febrile children to the emergency rooms or walk-in clinics of four hospitals in Riyadh. Parents of 560 febrile children were interviewed using a standard questionnaire to obtain sociodemographic information and current knowledge of fever. Approximately 70% of the respondents were female, and the ages of the most were in the range of 20-40 years. More than 80% of the parents had two or more children. RESULTS More than 70% of parents demonstrated a poor understanding of the definition of fever, high fever, maximum temperature of untreated fever, and threshold temperature warranting antipyresis. About 25% of parents considered temperatures less than 38.0 o C to be fever, another 25% did not know the definition of fever, 64% felt that temperatures of less than 40.0 o C could be dangerous to a child, and 25% could not define high fever. Another 23% believed that if left untreated, temperatures could rise to 42.0 o C or higher, but 37% could not provide an answer, and 62% did not know the minimum temperature for administering antipyretics. Approximately 95% of parents demonstrated undue fear of consequent body damage from fever, including convulsion, brain damage or stroke, coma, serious vague illness, blindness, and even death. CONCLUSION Parental misconceptions about fever reflect the lack of active health education in our community. Health professionals have apparently not done enough to educate parents on the condition of fever and its consequences, a common problem.
Endothelin B receptor antagonists attenuate subarachnoid hemorrhage-induced cerebral vasospasm.

BACKGROUND AND PURPOSE While it has been widely reported that the vasospasm following subarachnoid hemorrhage (SAH) is prevented/reversed by endothelin (ET) receptor antagonists selective for the ET(A) receptor and by nonselective ET receptor antagonists, ie, antagonists of both the ET(A) and ET(B) receptors, there are no reports on the possible attenuation of the spasm by selective ET(B) receptor antagonists. The purpose of this study was to investigate whether (1) ET(B) receptor antagonists prevent and reverse SAH-induced spasm and (2) attenuation of the spasm results from blockade of smooth muscle ET(B) (ET(B2)) receptor-mediated constriction and/or endothelial ET(B) (ET(B1)) receptor-mediated ET-1-induced ET-1 release. METHODS SAH-induced spasm of the rabbit basilar artery was induced with the use of a double hemorrhage model. In vivo effects of agents on the spasm were determined by angiography after their intracisternal infusion (10 microL/h) by mini osmotic pump. In situ effects of agents on the spasm were determined by direct measurement of vessel diameter after their suffusion in a cranial window. RESULTS SAH constricted the basilar artery by 30%. Intracisternal infusion with 10 micromol/L BQ788, an ET(B1/B2) receptor antagonist, reduced the spasm to 10%. To investigate whether BQ788 prevented the spasm by blockade of ET(B1) receptor-mediated ET-1-induced ET-1 release, as opposed to ET(B2) receptor-mediated constriction, we tested whether ET(B1) receptor blockade also prevented the spasm. Indeed, intracisternal infusion with 10 micromol/L RES-701-1, a selective ET(B1) receptor antagonist, reduced the spasm to 10%. Similarly, in situ superfusion with 1 micromol/L BQ788 reversed the spasm by 40%, and 1 micromol/L RES-701-1 reversed the spasm by 50%. However, both BQ788 and RES-701-1 enhanced by 40% to 50% the 3 nmol/L ET-1-induced constriction elicited in spastic vessels previously relaxed with 0.1 mmol/L phosphoramidon, an ET-converting enzyme inhibitor. CONCLUSIONS These results demonstrate that ET(B) receptor antagonists prevent and reverse SAH-induced cerebral vasospasm in an animal model. The likely mechanism underlying the attenuation of the spasm is blockade of ET(B1) receptor-mediated ET-1-induced ET-1 release of newly synthesized ET-1. These studies provide rationale for the therapeutic use of ET(B1) receptor antagonists to relieve the vasospasm following SAH, as well as other pathophysiological conditions involving possible ET-1-induced ET-1 release.
Parameterizing the Melting of Icebergs in Global Climate Models

Icebergs account for approximately half the freshwater flux into the ocean from the polar ice sheets, and play a major role in the distribution of melt water in the ocean, but their melting is currently parameterized in a rudimentary way in global climate models. In this thesis, a combination of observations, laboratory experiments, and numerical modeling is used to suggest improved iceberg melt rate parameterizations. This work is further introduced and motivated in Chapter 1. In Chapter 2, an observational record of icebergs in a Greenland fjord is used to show that icebergs subject to strongly sheared flows predominantly move with the vertical average of the ocean currents. If, as typical in iceberg parameterizations, only the surface ocean velocity is taken into account, iceberg speed and basal melt may have errors in excess of 60%. These results emphasize the need for parameterizations to consider ocean properties over the entire iceberg draft. A series of laboratory experiments conducted to determine the dependence of submarine iceberg side melting on a background flow is described in Chapter 3. It is shown that two distinct regimes of melting exist depending on the flow magnitude and consequent behavior of melt plumes (side-attached or side-detached), with correspondingly different meltwater spreading characteristics. These results are subsequently extended to ice blocks melting in a two-layer vertically sheared flow. Finally, an idealized numerical configuration is used in Chapter 4 to compare the three-equation parameterization of melt, developed for application under ice shelves, and the standardly used bulk parameterization of iceberg basal melt. The results suggest an updated velocity-independent version of this parameterization for use in calculating the basal melt rate of tabular icebergs, to account for the changes in ocean properties caused by the physical presence of a large iceberg in the ocean. The results of this thesis and their implications are discussed in Chapter 5.
Blind Equalization Techniques for xDSL using Channel Coding and Precoding

A new concept for digital communication over severe in- tersymbol interference producing channels, e.g., high-rate digital transmission over twisted pair lines (xDSL techniques) is proposed including channel coding, precoding, equalization, and synchroniza- tion. Channel coding improves data reliability or tolerable signal attenuation, e.g., field length, whereas a nonlinear predistortion method, a modification of the well-known T omlinson-Harashima precoding (THP) including signal shaping and dynamics limitation at the receiver side, is used in order to cope with intersymbol inter- ference. In contrast to prior approaches, a fixed compromise pre- coder together with a linear blind adaptive fine tuning equalizer at the receiver side is proposed in order to avoid any retransmission of channel measurement data to the receiver. By this, neither a block- ing of bidirectional communication can happen nor sophisticated start-up protocols are necessary. For this purpose new algorithms for blind adaptive equalization are introduced which are able to op- erate at very low signal-to-noise ratios due to channel coding and for highly correlated data sequences, typically for the application of precoding techniques. Additionally, methods for symbol timing syn- chronization are proposed.
The Contrast Effect in Temporal and Probabilistic Discounting

In this information age, messages related to time, and uncertainty surround us. At the same time, our daily lives are filled with decisions accompanied by temporal delay or uncertainty. Will such information influence our temporal and probabilistic discounting? The authors address this question from the perspectives of decision by sampling (DbS) theory and psychological distance theory. Studies 1 and 2 investigated the effect of contextual messages on temporal discounting and probabilistic discounting, respectively. The results indicated that participants who memorized messages about long-term and low-probability events rated delay or uncertainty as mentally closer and exhibited a less degree of value discounting than those who memorized messages regarding short-term and high-probability events. In addition, a sense of distance from present or reality mediated the effect of contextual messages on value discounting. The implications of the current findings for theory and applications are discussed.
Managing young upland forests in southeast Alaska for wood products, wildlife, aquatic resources, and fishes: problem analysis and study plan.

Wipfli, Mark S. ; Deal, Robert L. ; Hennon, Paul E. ; Johnson, Adelaide C. ; De Santo, Toni L. ; Hanley, Thomas A. ; Schultz, Mark E. ; Bryant, Mason D. ; Edwards, Richard T. ; Orlikowska, Ewa H. ; Gomi, Takashi. 2002. Managing young upland forests in southeast Alaska for wood products, wildlife, aquatic resources, and fishes: problem analysis and study plan. Gen. Tech. Rep. PNW-GTR-558. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 64 p. Red alder (Alnus rubra Bong.) appears to influence the productivity of young-growth conifer forests and affect the major resources (timber, wildlife, and fisheries) of forested ecosystems in southeast Alaska. We propose an integrated approach to understanding how alder influences trophic links and processes in young-growth ecosystems. The presence of red alder is expected to increase understory biomass, and aquatic, riparian, and terrestrial invertebrate abundance, providing more food for herbivores, fish, and birds. We predict that most red alder trees will die standing, and woody debris will be small and mobile in streams. Nitrogen fixation by red alder in mixed stands may result in larger, more commercially valuable conifers. Inclusion of red alder in the regenerating stand may therefore mitigate some negative impacts of clearcutting, and may increase total wood production from the landscape.
Predicting the performance of synchronous discrete event simulation

We develop a model to predict the performance of synchronous discrete event simulation. Our model considers the two most important factors for the performance of synchronous simulation: load balancing and communication. The effect of load balancing in a synchronous simulation is computed using probability distribution models. We derive a formula that computes the cost of synchronous simulation by combining a communication model called LogGP and computation granularity. Even though the formula is simple, it is effective in capturing the most important factors for the synchronous simulation. The formula helps us to predict the maximum speed up achievable by synchronous simulation. In order to examine the prediction model, we have simulated several large ISCAS logic circuits and a simple PCS network simulation on an SGI Origin 2000 and Terascale Computing System (TCS) at the Pittsburgh Supercomputing Center. The results of the experiment show that our performance model accurately predicts the performance of synchronous simulation. The performance model developed is used to analyze the effect of several factors that may improve the performance of synchronous simulation. The factors include problem size, load balancing, granularity, communication overhead, and partitioning.
Multiple Formaldehyde Oxidation/Detoxification Pathways in Burkholderia fungorum LB400

ABSTRACT Burkholderia species are free-living bacteria with a versatile metabolic lifestyle. The genome of B. fungorum LB400 is predicted to encode three different pathways for formaldehyde oxidation: an NAD-linked, glutathione (GSH)-independent formaldehyde dehydrogenase; an NAD-linked, GSH-dependent formaldehyde oxidation system; and a tetrahydromethanopterin-methanofuran-dependent formaldehyde oxidation system. The other Burkholderia species for which genome sequences are available, B. mallei, B. pseudomallei, and B. cepacia, are predicted to contain only the first two of these pathways. The roles of the three putative formaldehyde oxidation pathways in B. fungorum LB400 have been assessed via knockout mutations in each of these pathways, as well as in all combinations of knockouts. The resulting mutants have the expected loss of enzyme activities and exhibit defects of varying degrees of severity during growth on choline, a formaldehyde-producing substrate. Our data suggest that all three pathways are involved in formaldehyde detoxification and are functionally redundant under the tested conditions.
Probabilistic model for contextual retrieval

Contextual retrieval is a critical technique for facilitating many important applications such as mobile search, personalized search, PC troubleshooting, etc. Despite of its importance, there is no comprehensive retrieval model to describe the contextual retrieval process. We observed that incompatible context, noisy context and incomplete query are several important issues commonly existing in contextual retrieval applications. However, these issues have not been previously explored and discussed. In this paper, we propose probabilistic models to address these problems. Our study clearly shows that query log is the key to build effective contextual retrieval models. We also conduct a case study in the PC troubleshooting domain to testify the performance of the proposed models and experimental results show that the models can achieve very good retrieval precision.
